    Filipino Americans form the second-largest Asian American and Pacific Islanders subgroup. Growing evidence suggests that Filipino Americans have higher rates of diabetes than non-Hispanic whites. The key objectives of this study are 1) to determine the prevalence of diabetes in non-obese Filipino Americans compared to non-obese non-Hispanic whites, and 2) to identify risk factors for diabetes in non-obese Filipino men and women. Secondary analysis of population-based data from combined waves (2007, 2009 and 2011) of the adult California Health Interview Survey (CHIS). The study sample was restricted to non-obese Filipino Americans (n = 1629) and non-Hispanic whites (n = 72 072). Non-obese Filipino Americans had more than twice the odds of diabetes compared to non-Hispanic whites, even after correcting for several known risk factors (OR = 2.80, p < 0.001). For non-obese Filipino men, older age, poverty, cigarette smoking, and being overweight are associated with increased odds for diabetes, while older age was the only factor associated with diabetes among Filipina women. Diabetes prevention approaches need to be targeted towards non-obese Filipino Americans, due to their high risk of diabetes.

    Several cross-sectional studies in Pima Indians and Caucasians have indicated that obese individuals with type 2 diabetes have a higher basal metabolic rate (BMR) than healthy, obese individuals. However, no study has investigated this comparison in Japanese subjects, who are known to be susceptible to type 2 diabetes due to genetic characteristics. Thirty obese Japanese adults with pre-type 2 diabetes (n=7) or type 2 diabetes (n=13) or without diabetes (n=10) participated in this study. BMR was measured using indirect calorimetry. The relationships between residual BMR (calculated as measured BMR minus BMR adjusted for fat-free mass, fat mass, age, and sex) and biomarkers including fasting glucose, glycosylated hemoglobin (HbA(1c)), fasting insulin, homeostasis model assessment of insulin resistance (HOMA-R), triglycerides, and free fatty acids were examined using Pearson's correlation. BMR in diabetic subjects adjusted for fat-free mass, fat mass, age, and sex was 7.1% higher than in non-diabetic subjects. BMR in diabetic subjects was also significantly (pBMR and fasting glucose (r=0.391, p=0.032). These results indicate that in the Japanese population, obese subjects with type 2 diabetes have higher BMR compared with obese non-diabetic subjects. The fasting glucose level may contribute to these differences.

    Background: Globally, obesity is now recognised as an epidemic. The degree of obesity is proportional to the rate of development of cardiovascular diseases, hence, resulting in a dramatic increase in morbidity and mortality. Apart from obesity, diabetes mellitus is another well recognised risk factor contributing to coronary artery disease. The precise prevalence of obesity-related diabetes varies with age, race and gender; and is yet unknown in our population. We therefore, carried out study with the aim to determine the prevalence of diabetes mellitus in obese and non-obese patients with diagnosed coronary artery disease. Methods: This hospital based cross-sectional comparative study was conducted in Cardiology Department of Postgraduate Medical Institute, Lady Reading Hospital, Peshawar, from March 15, 2005 to May 30, 2006. A total of 200 patients with diagnosed coronary artery disease were enrolled, 100 were classified as obese and 100 as non-obese. Results: Among these, 139 patients were male and 61 female. A total of 88 were found to be diabetic, 54 of these were obese and 34 non-obese (p =0.004). Conclusion: Diabetes mellitus was significantly more frequent among obese patients with coronary artery disease as compared to non obese patients with coronary artery disease. (author)

    Introduction. Type 2 diabetes mellitus (T2DM) is one of the most important obesity-related comorbidities. This study was undertaken to characterise the effect of the biliopancreatic diversion with duodenal switch (BPD-DS) in morbidly obese and nonmorbidly obese diabetic patients. Methods. Outcome of 74 obese diabetic patients after BPD-DS and 16 non-obese diabetic patients after BPD or gastric bypass surgery was evaluated. Insulin usage, HbA(1c)-levels, and index of HOMA-IR (homeostasis model assessment of insulin resistence) were measured. Results. A substantial fraction of patients is free of insulin and shows an improved insulin sensitivity early after the operation, another fraction gets free of insulin in a 12-month period after the operation and a small fraction of long-term insulin users will not get free of insulin but nevertheless shows an improved metabolic status (less insulin needed, normal HbA(1c)-levels). Conclusion. BPD-DS leads to an improvement of T2DM in obese and non-obese patients. Nevertheless, more data is needed to clarify indications and mechanisms of action and to adjust our operation techniques to the needs of non-obese diabetic patients.

    Full Text Available In recent years, non-communicable diseases (NCD like obesity, hypertension (HTN and Type2 diabetes (T2DM are on the increase, specially in the developing nations. Body mass index (BMI, waist-to-hip ratio (WHR and Waist-to-height ratio (WHtR are used as indices of obesity to relate T2DM, HTN and coronary artery disease (CAD. This study addresses whether the risk of obesity for HTN differs between T2DM and non-DM subjects. We investigated 693 diabetic patients from BIRDEM and 2384 from communities. We measured height, weight, waist-girth, hip-girth and blood pressure. All subjects underwent oral glucose tolerance test (OGTT. BMI, WHR and WHtR were calculated. Systolic and diastolic hypertension (sHTN and dHTN were defined as SBP >=140 and DBP >= 90 mmHg, respectively. The prevalence of both sHTN and dHTN in T2DM was higher than the non-DM subjects (sHTN: 49.1 vs 14.3%, dHTN 19.6 vs. 9.5%. The comparison of characteristics between subjects with and without hypertension showed that the differences were significant for age, weight, waist-girth, BMI, WHR and WHtR for both T2DM and non-DM subjects (for all p<0.001. The increasing trend of hypertension with increasing obesity was observed more in the non-DM than in the T2DM subjects. The risk (OR of obesity for hypertension increased with increasing WHR and WHtR in the non-DM than the T2DM subjects. Compared with the non-DM the T2DM participants had two to three folds higher prevalence of HTN. In either group, BMI, WHR and WHtR were significantly higher in the hypertensive than the non-hypertensive subjects. The prevalence of hypertension increased with the increasing BMI, WHR and WHtR but significant only in the non-DM. Further studies may confirm these findings and determine whether there was any altered association between blood pressure and obesity in diabetes possibily, with or without autonomic neuropathy.

    Although obesity is known as a risk factor for several human cancers, the association of obesity with cancer recurrence and metastasis remains to be characterized. Here, B16-BL6 melanoma and Lewis lung carcinoma cells were intravenously injected into diabetic (db/db) and obese (ob/ob) mice. The number of experimental lung colonies was markedly promoted in these mice when compared with C57BL/6 mice. In contrast, tumor growth at the implanted site was comparable when cells were inoculated orthotopically. The use of B16-BL6 cells stably transfected with the luciferase gene revealed that the increased metastasis reflected a difference mainly within 6 hr after the intravenous inoculation of tumor cells. Administration of recombinant leptin in ob/ob mice abolished the increase in metastasis early on as well as the decrease in the splenic NK cell number. In addition, depletion of NK cells by an anti-asialo-GM1 antibody abrogated the enhanced metastasis in db/db mice. These results demonstrate that metastasis is markedly promoted in diabetic and obese mice mainly because of decreased NK cell function during the early phase of metastasis.

    OBJECTIVE: Epigenetic modifications contribute to the etiology of type 2 diabetes. METHOD: We performed genome-wide methylome and transcriptome analysis in liver from severely obese men with or without type 2 diabetes and non-obese men to discover aberrant pathways underlying the development...... in four of these genes in liver of severely obese non-diabetic and type 2 diabetic patients, suggesting epigenetic regulation of transcription by altered ATF-DNA binding. CONCLUSION: Severely obese non-diabetic and type 2 diabetic patients have distinct alterations in the hepatic methylome...... and transcriptome, with hypomethylation of several genes controlling glucose metabolism within the ATF-motif regulatory site. Obesity appears to shift the epigenetic program of the liver towards increased glycolysis and lipogenesis, which may exacerbate the development of insulin resistance....

    The risk of early-onset type 2 diabetes associated with the severity of obesity in youth is not well understood. This study aims to determine metabolic alterations and type 2 diabetes risk among American Indian children who are obese or severely obese. Incidence rates of diabetes before 20 years (youth-onset) and 45 years were computed in 2728 children who were from 5 to Obesity was defined as age-sex-adjusted body mass index (BMI) ≥95th percentile, and its severity was quantified as the percentage of the 95th percentile (%BMI p95 ). In the younger cohort, 0.9% of those non-obese and 2.9% of those with 100% to obese and 9.8% of those with 100% to youth-onset diabetes was 3.8 and 4.9/1000 person-years in the child and adolescent cohorts, respectively, and before the age of 45 was 12.3 and 16.8/1000 person-years, respectively. Incidence rates of youth-onset diabetes in those with the most severe obesity (≥140%BMI p95 ) were 2.3 to 5.1 times as high as in those with the least severe obesity (100 to obesity in an American Indian population is a major driver of type 2 diabetes developing in adolescents and young adults.

    Most individuals who have non-insulin-dependent diabetes mellitus are obese. The obese population has proved a frustrating entity regarding weight loss and diabetes control. Results of medical weight loss programs, medications, and behavior therapy have proved disappointing. Bariatric surgery is the most effective method of diabetes management and cure in the morbidly obese population. Surgical procedures to cause malabsorption provide a more dramatic effect on diabetes owing to the imparted bypass of the hormonally active foregut. Pertinent journal articles spanning the last 40 years, as well as textbooks. Bariatric surgical procedures have proven a much more successful method of weight loss and diabetes control in the obese population than conservative methods. These surgical procedures have proven safe with reported mortality rates of 0% to 1.5%. Bariatric operations may be divided based on the method of weight loss and effect on diabetes. The first category is restrictive and includes vertical banded gastroplasty and adjustable silicone gastric banding. These operations improve diabetes by decreasing food intake and body weight with a slowing of gastric emptying. The second category not only contains restrictive components but also elements of malabsorption. This category includes the Roux-en-Y gastric bypass and biliary-pancreatic diversion, which bypass the foregut. Although all of the surgical procedures for obesity offer improved weight loss and diabetes control compared with conservative methods, the Roux-en-Y gastric bypass and biliary-pancreatic diversion offer superior weight loss and resolution of diabetes. The more dramatic effect seen in the surgical procedures to cause malabsorption is likely secondary to the bypass of the foregut resulting in increased weight loss and elevation of the enteroglucagon level.

    Certain human subpopulations are metabolically healthy but obese, or metabolically obese but normal weight; such mutations uncouple obesity from glucose intolerance, revealing pathways implicated in Type 2 diabetes. Current searches for relevant genes consume significant effort. We have reported previously a novel double bromodomain protein called Brd2, which is a transcriptional co-activator/co-repressor with SWI/SNF (switch mating type/sucrose non-fermenting)-like functions that regulates chromatin. In the present study, we show that wholebody disruption of Brd2, an unusual MHC gene, causes lifelong severe obesity in mice with pancreatic islet expansion, hyperinsulinaemia, hepatosteatosis and elevated pro-inflammatory cytokines, but, surprisingly, enhanced glucose tolerance, elevated adiponectin, increased weight of brown adipose tissue, heat production and expression of mitochondrial uncoupling proteins in brown adipose tissue, reduced macrophage infiltration in white adipose tissue, and lowered blood glucose, leading to an improved metabolic profile and avoiding eventual Type 2 diabetes. Brd2 is highly expressed in pancreatic beta-cells, where it normally inhibits beta-cell mitosis and insulin transcription. In 3T3-L1 pre-adipocytes, Brd2 normally co-represses PPAR-gamma (peroxisome-proliferator-activated receptor-gamma) and inhibits adipogenesis. Brd2 knockdown protects 3T3-L1 adipocytes from TNF-alpha (tumour necrosis factor-alpha)-induced insulin resistance, thereby decoupling inflammation from insulin resistance. Thus hypomorphic Brd2 shifts energy balance toward storage without causing glucose intolerance and may provide a novel model for obese metabolically healthy humans.

    Patients with diabetes retinopathy appear to show increased susceptibility to periodontal disease. This study was performed to assess the relationship between periodontitis and the prevalence of diabetic retinopathy in a large probability sample of the Korean population. A subgroup analysis was performed using body mass index diabetic retinopathy in relation to demographic variables and anthropometric characteristics of the participants is presented as means with their standard errors. The presence of periodontitis and presence of retinopathy categorized by body mass index (diabetic retinopathy after adjustment with variables, including age, sex, smoking, drinking, exercise, hypertension, metabolic syndrome, HbA1c, and duration of diabetes mellitus. There was a statistically significant increase in the prevalence of periodontitis in individuals who had proliferative diabetic retinopathy. The odds ratios [95% confidence intervals] of prevalence of diabetic retinopathy were 1.193 [0.757-1.881] for the whole population after adjustments with confounding factors. Subgroup analysis after adjustments with confounding factors showed that the odds ratios [95% confidence intervals] of prevalence were 2.206 [1.114-4.366] and 0.588 [0.326-1.061] among participants with body mass index diabetic retinopathy was positively associated with the presence of periodontitis in non-obese diabetic Korean adults after adjustment with confounding variables. Our findings suggest that when a periodontist finds the presence of periodontitis in non-obese diabetic patients, timely evaluation of the patient's ophthalmic evaluation should be 44 recommended.

    Previous studies have implicated B lymphocytes in the pathogenesis of diabetes in the non-obese diabetic (NOD) mouse. While it is clear that B lymphocytes are necessary, it has not been clear at which stage of disease they play a role; early, late or both. To clarify when B lymphocytes are needed, T lymphocytes were transferred from 5-week-old NOD female mice to age-matched NOD/severe combined immunodeficiency (SCID) recipient mice. NOD/SCID mice, which lack functionally mature T and B lymphocytes, do not normally develop insulitis or insulin-dependent diabetes melitus (IDDM). The NOD/SCID mice that received purified T lymphocytes from 5-week-old NOD mice subsequently developed insulitis and diabetes even though they did not have detectable B lymphocytes. This suggests that while B lymphocytes may be essential for an initial priming event they are not requisite for disease progression in the NOD mouse.

    Non-fasting triglyceridemia is much closer associated to cardiovascular risk compared to fasting triglyceridemia. We hypothesized that there would be acute differential effects of four common dietary proteins (cod protein, whey isolate, gluten, and casein) on postprandial lipemia in obese non......-diabetic subjects. To test the hypothesis we conducted a randomized, acute clinical intervention study with crossover design. We supplemented a fat rich mixed meal with one of four dietary proteins i.e. cod protein, whey protein, gluten or casein.

    Objective To create a decision analytic model to estimate the balance between treatment risks and benefits for severely obese patients with diabetes. Summary Background Data Bariatric surgery leads to many desirable metabolic changes, but long-term impact of bariatric surgery on life expectancy in patients with diabetes has not yet been quantified. Methods We developed a Markov state transition model with multiple Cox proportional hazards models and logistic regression models as inputs to compare bariatric surgery versus no surgical treatment for severely obese diabetic patients. The model is informed by data from three large cohorts: 1) 159,000 severely obese diabetic patients (4,185 had bariatric surgery) from 3 HMO Research Network sites, 2) 23,000 subjects from the Nationwide Inpatient Sample (NIS), and 3) 18,000 subjects from the National Health Interview Survey linked to the National Death Index. Results In our main analyses, we found that a 45 year-old female with diabetes and a BMI of 45 kg/m2 gained an additional 6.7 years of life expectancy with bariatric surgery (38.4 years with surgery vs. 31.7 without). Sensitivity analyses revealed that the gain in life expectancy decreased with increasing BMI, until a BMI of 62 kg/m2 is reached, at which point nonsurgical treatment was associated with greater life expectancy. Similar results were seen for both men and women in all age groups. Conclusions For most severely obese patients with diabetes, bariatric surgery appears to improve life expectancy; however, surgery may reduce life expectancy for the super obese with BMIs over 62 kg/m2.

    Higher fetuin-A expression is linked to both obesity and type 2 diabetes mellitus (T2DM), However, studies in non-obese patients with T2DM are scarce. 345 newly diagnosed T2DM patients and 300 subjects with normal glucose tolerance (NGT) were divided into obese and non-obese subgroups, respectively. Serum fetuin-A and adiponectin levels and related parameters were measured. T2DM patients with obesity had higher fetuin-A levels compared with non-obese patients and obese NGT subjects (p<0.001). Significant correlations were observed between fetuin-A and most metabolic parameters in obese NGT and T2DM subjects, but which was not in non-obese patients with T2DM. The independent associations were found between fetuin-A and free fatty acids, HOMA-IR, C-reactive protein and adiponectin only in obese NGT and T2DM subjects (all p<0.05). The adjusted odds ratios for obesity were increased with increasing quartile of fetuin-A in both T2DM and NGT subjects in logistic regression models (p for trend<0.001), but which was more significant in T2DM patients. Higher serum fetuin-A levels in obese T2DM patients compared with non-obese patients and obese NGT subjects supports the hypothesis that fetuin-A may be as a bridge connecting obesity and obesity-related T2DM.

    Objective: To find out the rate of respiratory tract infections in diabetic and non-diabetic individuals and their relation with surfactant protein D. Methods: The cross-sectional study was conducted at Dow University of Health Sciences, Karachi, from September 2011 to April 2012, and comprised subjects of both genders between ages of 30 and 60 years. The subjects were divided into four groups: diabetic obese, non-diabetic obese, diabetic non-obese, and non-diabetic-non-obese. A structured questionnaire was used to collect information about respiratory tract infections. Serum surfactant protein D levels were analysed using human surfactant protein D enzyme-linked immunosorbent assay kit. Statistical analysis was performed using SPSS 16. Results: Of the 90 subjects, there were 20(22.2 percent) diabetic obese, 30(33.3 percent) non-diabetic obese, 10(11.1 percent) diabetic non-obese, and 30(33.3 percent) non-diabetic-non-obese. The overall mean age was 36.6±103 years. Among the diabetic obese, 15(75 percent) had respiratory tract infections which was higher than the other study groups, and patients having respiratory tract infections had lower surfactant protein D levels than those who did not have infections (p=0.01). Conclusion: Diabetic obese subjects had greater rate of recurrent respiratory tract infections and had lower concentration of serum surfactant protein D compared to subjects without respiratory tract infections.

    Periodontal disease is closely related to type 2 diabetes and is an important complication of diabetes. There are few studies about the relationship the glycohemoglobin levels with severity of periodontitis in non-diabetic population. We therefore planned this study to evaluate the glycohemoglobin levels with severity of periodontitis in non-diabetic population. This study was conducted on 50 age and gender matched subjects in each of the three groups (according to the grades of mobility in periodontitis), a total of 150 non-diabetic periodontitis patients (Grade 1, Grade 2, and Grade 3 mobility) and 50 non-diabetic periodontitis patients with Grade 0 mobility (controls), in collaboration with the Department of Periodontics of Dental College and Department of Biochemistry, PGIMS, Rohtak, Haryana. After obtaining informed consent, fasting venous blood samples of all the non-diabetic periodontitis patients of all grades were collected aseptically for HbA1c, plasma glucose, and serum C-reactive protein (CRP) estimation. A total of 150 non-diabetic periodontitis patients (Grade 1, Grade 2, and Grade 3 mobility) and 50 age and gender matched controls participated in the study. There was no significant difference in fasting plasma glucose and postprandial plasma glucose in non-diabetic periodontitis patients with Grade 1, Grade 2, and Grade 3 mobility as compared to controls, non-diabetic periodontitis patients with Grade 1 mobility as compared to Grade 2, non-diabetic periodontitis patients with Grade 1 mobility as compared to Grade 3 and non-diabetic periodontitis patients with Grade 2 mobility as compared to Grade 3. Glycohemoglobin and serum C-reactive protein levels were significantly increased in non-diabetic periodontitis patients with Grade 1, Grade 2, and Grade 3 mobility as compared to controls, non-diabetic periodontitis patients with Grade 1 mobility as compared to Grade 3 and non-diabetic periodontitis patients with Grade 2 mobility as compared to Grade 3

    Conclusion: Severely obese non-diabetic and type 2 diabetic patients have distinct alterations in the hepatic methylome and transcriptome, with hypomethylation of several genes controlling glucose metabolism within the ATF-motif regulatory site. Obesity appears to shift the epigenetic program of the liver towards increased glycolysis and lipogenesis, which may exacerbate the development of insulin resistance.

    To examine whether the reduced incidence of preeclampsia in non-diabetic obese pregnant women treated with metformin is mediated by changes in insulin resistance. This was a secondary analysis of obese pregnant women in a randomised trial (MOP trial). Fasting plasma glucose and insulin were measured in 384 of the 400 women who participated in the MOP trial. Homeostasis model assessment of insulin resistance (HOMA-IR) was compared in the metformin and placebo groups and in those that developed preeclampsia versus those that did not develop preeclampsia. At 28 weeks, median HOMA-IR was significantly lower in the metformin group. Logistic regression analysis demonstrated that there was a significant contribution in the prediction of preeclampsia from maternal history of chronic hypertension and gestational weight gain, but not HOMA-IR either at randomisation ( p  = 0.514) or at 28 weeks ( p  = 0.643). Reduced incidence of preeclampsia in non-diabetic obese pregnant women treated with metformin is unlikely to be due to changes in insulin resistance.

    Full Text Available Background: Metformin reduces maternal and neonatal weight gain in gestational diabetes mellitus; however, this effect is poorly investigated in non-diabetic women. Objective: We performed this meta-analysis to investigate the effect of metformin intake during pregnancy on maternal and neonatal outcomes in obese non-diabetic women. Materials and Methods: We searched Medline, EMBASE, and Cochrane CENTRAL for eligible randomized controlled trials addressing the efficacy of metformin in pregnant obese non-diabetic women. Data were extracted and analyzed using RevMan software (Version 5.3. Neonatal birth weight was the key outcome. Secondary outcomes included maternal weight gain, the incidence of preeclampsia, and neonatal adverse effects (miscarriage, stillbirth and congenital anomalies. Results: Pooled data from two RCTs (n=843 showed that metformin caused a significant reduction in maternal gestational weight gain (MD-1.35, 95% CI: [2.08, -0.630], compared to placebo. The summary effect-estimate did not favor either of the two groups in terms of reduction of neonatal birth weight Z score (MD-0.09, 95% CI: [0.23, 0.06]. Metformin was associated with 41% reduction in the risk of preeclampsia; however, this reduction was not statistically significant [RR 0.59, 95% CI: [0.03, 11.46]. None of the neonatal adverse events including stillbirth [RR 1.14, 95% CI: 0.42, 3.10] and congenital anomalies (RR= 1.36, 95% CI: [0.58, 3.21] differed significantly between the two groups. Conclusion: For obese pregnant women, metformin could decrease gestational weight gain with no significant reduction in neonatal birth weight. In light of the current evidence, metformin should not be used to prevent poor pregnancy outcomes in obese non-diabetic women.

    Full Text Available Lipotoxicity of the heart has been implicated as a leading cause of morbidity in Type 2 Diabetes Mellitus (T2DM. While numerous reports have demonstrated increased myocardial fatty acid (FA utilization in obese T2DM animal models, this diabetic phenotype has yet to be demonstrated in non-obese animal models of T2DM. Therefore, the present study investigates functional, metabolic, and genomic differences in myocardial FA metabolism in non-obese type 2 diabetic rats. The study utilized Goto-Kakizaki (GK rats at the age of 24 weeks. Each rat was imaged with small animal positron emission tomography (PET to estimate myocardial blood flow (MBF and myocardial FA metabolism. Echocardiograms (ECHOs were performed to assess cardiac function. Levels of triglycerides (TG and non-esterified fatty acids (NEFA were measured in both plasma and cardiac tissues. Finally, expression profiles for 168 genes that have been implicated in diabetes and FA metabolism were measured using quantitative PCR (qPCR arrays. GK rats exhibited increased NEFA and TG in both plasma and cardiac tissue. Quantitative PET imaging suggests that GK rats have increased FA metabolism. ECHO data indicates that GK rats have a significant increase in left ventricle mass index (LVMI and decrease in peak early diastolic mitral annular velocity (E' compared to Wistar rats, suggesting structural remodeling and impaired diastolic function. Of the 84 genes in each the diabetes and FA metabolism arrays, 17 genes in the diabetes array and 41 genes in the FA metabolism array were significantly up-regulated in GK rats. Our data suggest that GK rats' exhibit increased genomic disposition to FA and TG metabolism independent of obesity.

    Full Text Available Background. Obesity, diabetes and different lipid metabolic disorders are the most frequent risk factors for nonalcoholic fatty liver disease, presented with a high variability in clinical and histological findings. Case report. We presented a case of 37-year-old male, suffering from type 2 diabetes mellitus, grade III obesity (BMI 45 kg/m2 and multiple metabolic disorders. Abdominal ultrasound revealed hepatomegaly during the last six months. Laboratory diagnostics showed increased serum transaminase levels. Serologic markers for viral hepatitis B and C were negative. The patient denied significant alcohol consumption. Liver biopsy and pathohistologic finding revealed macro- (III grade and microvesicular (I grade fatty degeneration, as well as mixed-cell portal infiltration with moderate liver fibrosis, corresponding to the typical presentation of NASH (Non Alcoholic Steatohepatitis. Conclusion. NASH treatment options include the reduction of body mass and an adequate antidiabetic and dislipidemia treatment. The aim of all therapeutic measures was to stop the progression of the disease, to prevent the progression of fibrosis and the development of of cirrhosis. .

    Mortality according to body mass index (weight/height2) was studied in 2197 Pima Indians aged 15-74 years, as part of the longitudinal study of diabetes begun in 1965 in the Gila River Indian Community of Arizona. The Pima Indians are a population with a high prevalence of obesity, and they have the highest known incidence of type II (non-insulin dependent) diabetes mellitus. Among males, mortality was greatest in those with a body mass index of at least 40 kg/m2, but obesity had little effect on mortality at body mass indices below 40 kg/m2. Age-specific death rates in women were not consistently related to obesity, although mortality in subjects with diabetes was higher than in those without. In men, diabetes had little effect on mortality. In this study, as in several other mortality studies, the lowest mortality rates were experienced by people with body weights well above those recommended as "desirable" by the Society of Actuaries in 1959. Thus, the applicability of the "desirable" weight standards in common use is questioned.

    To estimate the proportion of diabetes, obesity and non-optimum blood pressure levels in a group of employees of the University of Puerto Rico Medical Sciences Campus that participated in a diabetes health fair at the "Centro de Diabetes para Puerto Rico". A total of 113 participants of the diabetes health fair completed a questionnaire to obtain demographic characteristics and the frequency of self-reported diabetes. The nursing staff examined the participants in order to obtain the following clinical characteristics: body mass index, blood pressure and blood glucose levels. The proportion of self-reported diabetes, obesity (> or = 30 kg/m2) and non-optimum blood pressure levels (systolic > or = 20 mm/Hg or diastolic > or = 80 mm/Hg) were 15.4% (95% CI: 8.5% - 25.7%), 80.0% (95% CI: 70.8%-86.9%) and 70.5% (95% CI: 61.1%-78.6%), respectively. Although it was not statistically significant, diabetes was higher among females (15.4%) compared to males (12.0%). All participants with self-reported diabetes were overweight or obese, and 91.7% showed non-optimum blood pressure levels. A significant positive correlation (p diabetes, obesity, and non-optimum blood pressure levels in this sample of Medical Sciences Campus employees underscores the need for confirming these results in a larger study and developing strategies focused on reducing health risks in this population.

    2014-09-01

    Severe obesity is increasing in adolescents and is associated with cardiovascular disease, type 2 diabetes mellitus, obstructive sleep apnoea, polycystic ovarian syndrome and a range of musculoskeletal problems. Premature death is the inevitable outcome of persistent severe obesity in adolescents. In adults with severe obesity, medical and lifestyle interventions have been shown to be expensive and less effective in terms of weight loss than has bariatric surgery. The single completed randomised controlled trial in adolescents shows the same outcome. This is supported by meta analyses of bariatric surgery in adolescent subjects. A more aggressive approach to severe obesity, utilising bariatric surgery in selected cases, within the context of a multi-disciplinary team, is required. Copyright © 2014.

    INTRODUCTION: The dramatic rise in the prevalence of obesity and type 2 diabetes mellitus (T2DM) is associated with increased mortality, morbidity as well as public health care expenses worldwide. The need for effective and long-lasting pharmaceutical treatment is obvious. The record of anti-obesity...... drugs has been poor so far and the only efficient treatment today is bariatric surgery. Research has indicated that appetite inhibiting hormones from the gut may have a therapeutic potential in obesity. The gut incretin hormone, glucagon-like peptide-1 (GLP-1), appears to be involved in both peripheral...... and central pathways mediating satiety. Clinical trials have shown that two GLP-1 receptor agonists exenatide and liraglutide have a weight-lowering potential in non-diabetic obese individuals. Furthermore, they may also hold a potential in preventing diabetes as compared to other weight loss agents. AREAS...

    Full Text Available Background: Degenerative lumbar spinal stenosis (LSS is a common condition affecting mainly old age group with high incidence and prevalence, and is associated with many factors. Aim: Our study aimed to evaluate smoking, diabetes mellitus and obesity associations with degenerative LSS. Patients and methods: A comparative crosssectional study with participants aged 60 years or older. Participants suffering from degenerative LSS were enrolled as the diseased group after diagnosis with MRI, healthy persons (age and gender matched were considered as control group. Smoking, diabetes mellitus and obesity variables were collected and analyzed using chi-square and odds ratio. Results: Around 162 participants enrolled the study, 62 were considered as degenerative LSS group, whereas 100 were considered as the control group. In LSS group, a picture obtained was of 20:42 smokers to non-smoker, 22:20 diabetic to non-diabetic, 37:25 obese to non-obese. While in the controlled group a picture was obtained with 18:82 smokers to non-smoker, 18-82 diabetic to non-diabetic, 34:66 obese to non-obese. Chi-square p-value was of 0.037, 0.012 and 0.001 for smoking, diabetes mellitus, and obesity, respectively. The odd ratio was 2.17, 2.5 and 2.87 for smoking, diabetes mellitus, and obesity, respectively. All above results were significant. Conclusion: Each of smoking, diabetes mellitus, and obesity has a great association with the development of degenerative LSS in elderly age group. Obesity shows the highest association among them

In this article, we will discuss the epidemiology and impact of diabetes and obesity and will also outline the comp...

  1. Plasma metabolomic profiles reflective of glucose homeostasis in non-diabetic and type 2 diabetic obese African-American women.

    Oliver Fiehn

    2010-12-01

    Full Text Available Insulin resistance progressing to type 2 diabetes mellitus (T2DM is marked by a broad perturbation of macronutrient intermediary metabolism. Understanding the biochemical networks that underlie metabolic homeostasis and how they associate with insulin action will help unravel diabetes etiology and should foster discovery of new biomarkers of disease risk and severity. We examined differences in plasma concentrations of >350 metabolites in fasted obese T2DM vs. obese non-diabetic African-American women, and utilized principal components analysis to identify 158 metabolite components that strongly correlated with fasting HbA1c over a broad range of the latter (r = -0.631; p<0.0001. In addition to many unidentified small molecules, specific metabolites that were increased significantly in T2DM subjects included certain amino acids and their derivatives (i.e., leucine, 2-ketoisocaproate, valine, cystine, histidine, 2-hydroxybutanoate, long-chain fatty acids, and carbohydrate derivatives. Leucine and valine concentrations rose with increasing HbA1c, and significantly correlated with plasma acetylcarnitine concentrations. It is hypothesized that this reflects a close link between abnormalities in glucose homeostasis, amino acid catabolism, and efficiency of fuel combustion in the tricarboxylic acid (TCA cycle. It is speculated that a mechanism for potential TCA cycle inefficiency concurrent with insulin resistance is "anaplerotic stress" emanating from reduced amino acid-derived carbon flux to TCA cycle intermediates, which if coupled to perturbation in cataplerosis would lead to net reduction in TCA cycle capacity relative to fuel delivery.

    Objective: To assess the body mass index and waist circumferences of high risk non diabetic young individuals and compare them with low risk non diabetic young individuals. Method: A cross sectional, case control comparative study was conducted in the department of medicine, LUMHS from January 2008 to March 2009. Five hundred individuals 20-40 years of age were selected and divided into two groups i.e. Group A: high risk (250 individuals) and Group B: low risk (250 individuals) on the basis of same age and gender. Group A included those who had positive family history of type 2 DM in first degree relatives while group B had no family history of type 2 DM in first degree relatives. The blood pressure, BMI and Waist Circumference was measured and Fasting Blood Sugar was estimated in each individual. In each group 125 (50%) were males and 125 (50%) were females. Results: In group A 58% and in group B 28.8% individuals represented raised BMI whereas 42% in group A and 36% in group B individuals showed an increased waist circumference. Mean fasting blood glucose was significantly higher in Group A than in Group B (P=0.001). Conclusion: Impaired Fasting Glucose is strongly associated with family history of type 2 diabetes mellitus. Presence of obesity specially in high risk non-diabetic young individuals emphasize the need for routine health screening for early institution of preventive measures. (author)

    This study examined a graduated severity level approach to food addiction classification against associations with World Health Organization obesity classifications (body mass index, kg/m 2 ) among 408 people with type 2 diabetes. A survey including the Yale Food Addiction Scale and several demographic questions demonstrated four distinct Yale Food Addiction Scale symptom severity groups (in line with Diagnostic and Statistical Manual of Mental Disorders (5th ed.) severity indicators): non-food addiction, mild food addiction, moderate food addiction and severe food addiction. Analysis of variance with post hoc tests demonstrated each severity classification group was significantly different in body mass index, with each grouping being associated with increased World Health Organization obesity classifications. These findings have implications for diagnosing food addiction and implementing treatment and prevention methodologies of obesity among people with type 2 diabetes.

    Roux-en-Y gastric bypass surgery is widely applied to ameliorate morbid obesity, including diabetes in people with type 2 diabetes. The latter vanish a few days after surgery for many, but not in all patients before any weight reduction has occurred. The explanation for this change in metabolic status is poorly understood, but the observation may suggest that the fate obesity and diabetes is only partly linked after surgery. The trajectories of weight reduction measured as reduced body mass index (BMI) in 741obese subjects with and without diabetes were evaluated. Evaluation was performed on three groups: 1) subjects that were non-diabetic before and after surgery; 2) subjects that were diabetics before surgery but non-diabetics after surgery; and 3) subjects that were diabetics before surgery and remained diabetics after surgery. The diabetic state was established at HbA1c above 48 mmol/mol. The trajectories differ significantly between groups and any sub-populations of groups, the latter identified by the distance between individual trajectories using a k-means procedure. The results suggest that different domains in the enormous genetic network governing basic metabolism are perturbed in obesity and diabetes, and in fact some of the patients are affected by two distinct diseases: obesity and diabetes mellitus type 2. Although RYGB "normalized" many glycaemic parameters in some of the diabetic subjects apparently converting to a non-diabetics state, other diabetic subjects stay diabetic in the context of the new gut anatomy after surgery. Thus, the obesity part of the glycaemic derangement may have been ameliorated, but some defects of the diabetic state had not.

    Obesity is being recognized as a major public health problem of global significance. The prevalence of obesity is increasing worldwide and also in China. Studies indicated that obesity is the major risk factor for several chronic degenerative diseases including cardiovascular disease, diabetes mellitus, and hypertension. However, the underlying mechanism of obesity development and its relation to non-insulin dependent diabetes mellitus (NIDDM) is not well understood. The major aim of the proposed research study is to investigate the effect of energy intake and expenditure on body composition and obesity development, and to identify obesity and NIDDM risk factors. This study will be conducted in 100 men and women aged 65 living in urban Beijing, China. 2-H and 18-O will be used for body composition and energy expenditure measurements, energy intake by a 3-day food weighted method, physical activity level by questionnaire, insulin determinations by radioimmunoassay (RIA). Demographic data of the subjects will also be collected. We anticipate that the results of this study would help us understand the underlying mechanism of obesity and the relation of obesity to NIDDM in Chinese aging population, so that effective strategies can be identified for prevention and management of obesity and NIDDM.

    Hypertriglyceridemia (HTG) is a risk factor for atherosclerotic cardiovascular disease (CVD). We investigated alterations in plasma metabolites associated with borderline-to-moderate HTG (triglycerides (TG) 150-500 mg/dL). Using UPLC-LTQ-Orbitrap mass spectrometry analysis, the metabolomics profiles of 111 non-diabetic and non-obese individuals with borderline-to-moderate HTG were compared with those of 111 age- and sex-matched controls with normotriglyceridemia (NTG, TG amides, including N-ethyldodecanamide (q = 2.9E-05), N-propyldodecanamide (q = 3.5E-05), palmitoleamide (q = 2.9E-06), and palmitic amide (q = 0.019). The metabolomic profiles of the HTG group also exhibited lower plasma levels of cis-4-octenedioic acid (qamides, and cis-4-octenedioic acid among non-diabetic and non-obese individuals with borderline-to-moderate HTG. These results provide novel insights into the metabolic alterations that occur in the early metabolic stages of HTG. This information may facilitate the design of early interventions to prevent disease progression. PMID:25856314

    Full Text Available Obstructive sleep apnea (OSA is common in obese patients with type 2 diabetes mellitus (DM and may contribute to diabetic microvascular complications.To investigate the association between OSA, hypoxemia during sleep, and diabetic retinal complications in severe obesity. This was a prospective observational study of 93 obese patients mean (SD age: 52(10 years; mean (SD body mass index (BMI: 47.3(8.3 kg/m(2 with DM undergoing retinal screening and respiratory monitoring during sleep. OSA was defined as apnea-hypopnea index (AHI of ≥15 events/hour, resulting in two groups (OSA+ vs. OSA-.Forty-six patients were OSA+: median (95% CI AHI = 37(23-74/hour and 47 were OSA-ve (AHI = 7(4-11/hour. Both groups were similar for ethnicity, BMI, cardiovascular co-morbidities, diabetes duration, HbA1c, and insulin treatment (p>0.05. The OSA+ group was significantly more hypoxemic. There was no significant difference between OSA+ and OSA- groups for the presence of retinopathy (39% vs. 38%. More OSA+ subjects had maculopathy (22% vs. 13%, but this did not reach statistical significance. Logistic regression analyses showed that AHI was not significantly associated with the presence of retinopathy or maculopathy (p>0.05. Whilst minimum oxygen saturation was not significantly associated with retinopathy, it was an independent predictor for the presence of maculopathy OR = 0.79 (95% CI: 0.65-0.95; p<0.05, after adjustment.The presence of OSA, as determined by AHI, was not associated with diabetic retinal complications. In contrast, severity of hypoxemia during sleep (minimum oxygen saturations may be an important factor. The importance of hypoxia in the development of retinal complications in patients with OSA remains unclear and further studies assessing the pathogenesis of hypoxemia in patients with OSA and diabetic retinal disease are warranted.

    For many physicians, the concept of surgery as the best treatment for a medical disease such as diabetes, cardiovascular problems, hyperlipidemia, sleep apnea, hepatosteatosis, GERD, osteoarthritis, psoriasis, rheumatoid arthritis, or infertility, still sounds wrong and just a ploy by surgeons to increase their business. Since 2011, however, several non-surgical societies have recommended Weight Loss Surgery - The International Diabetes Federation, The American Diabetes Association, American Heart Association, and Obesity Society in 2015 for patients with body mass index (BMI) greater than 35 and diabetes, and to decrease cardiovascular risk factors.1 The concept is to treat the common underlying problem, which is obesity, with the most effective method for immediate and long-term weight loss, which is surgery. The term "metabolic" surgery was therefore coined to accurately describe the effects of weight loss (bariatric) surgery. Our specialty society named itself the American Society for Metabolic and Bariatric Surgery (ASMBS). [Full article available at http://rimed.org/rimedicaljournal-2017-03.asp].

    BACKGROUND: Roux-en-Y gastric bypass surgery is widely applied to ameliorate morbid obesity, including diabetes in people with type 2 diabetes. The latter vanish a few days after surgery for many, but not in all patients before any weight reduction has occurred. The explanation for this change...... in metabolic status is poorly understood, but the observation may suggest that the fate obesity and diabetes is only partly linked after surgery. METHODS: The trajectories of weight reduction measured as reduced body mass index (BMI) in 741obese subjects with and without diabetes were evaluated. Evaluation...... was performed on three groups: 1) subjects that were non-diabetic before and after surgery; 2) subjects that were diabetics before surgery but non-diabetics after surgery; and 3) subjects that were diabetics before surgery and remained diabetics after surgery. The diabetic state was established at HbA1c above...

  10. Prioritizing Environmental Chemicals for Obesity and Diabetes ...

    Science.gov (United States)

    Background: Diabetes and obesity are major threats to public health in the US and abroad. Understanding the role chemicals in our environment play in the development of these conditions is an emerging issue in environmental health, although identifying and prioritizing chemicals for testing beyond those already implicated in the literature is a challenge. This review is intended to help researchers generate hypotheses about chemicals potentially contributing to diabetes and obesity-related health outcomes by summarizing relevant findings from the US Environmental Protection Agency (EPA) ToxCast high-throughput screening (HTS) program. Objectives: To develop new hypotheses around environmental chemicals of potential interest for diabetes- or obesity-related outcomes using high throughput screening data. Methods: Identify ToxCast assay targets relevant to several biological processes related to diabetes and obesity (insulin sensitivity in peripheral tissue, pancreatic islet and beta cell function, adipocyte dierentiation, and feeding behavior) and present chemical screening data against those assay targets to identify chemicals of potential interest. Discussion: Results of this screening-level analysis suggest that the spectrum of environmental chemicals to consider in research related to diabetes and obesity is much broader than indicated from research papers and reviews published in the peer-reviewed literature. Testing of hypotheses based on ToxCast data will a

    The rise in prevalence of diabetes is alarming and research ascribes most of the increase to lifestyle. However, little knowledge exists about the influence of occupational factors on the risk for developing diabetes. This study estimates the importance of work and lifestyle as risk factors for developing diabetes mellitus among healthcare workers and explores the association of work factors and obesity, which is a risk factor for diabetes. Questionnaire-based prospective cohort study among 7,305 health care workers followed for seven years in the Danish National Diabetes Register. We used bivariate comparisons to give an unadjusted estimate of associations, followed by adjusted survival analysis and logistic regression models to estimate the influences of potential risk factors related to job, health and lifestyle on diabetes and obesity. During seven years of follow up, 3.5% of participants developed diabetes, associated with obesity (HR  =  6.53; 95% CI 4.68-9.10), overweight (HR  =  2.89; CI 2.11-3.96) age 50-69 y (HR  =  2.27; 95% CI 1.57-3.43) and high quality of leadership (HR  =  1.60; CI 1.19-2.16). Obesity at baseline was most common among the youngest employees, and was mainly associated with developing diabetes (OR  =  3.84; CI 2.85-5.17), impaired physical capacity and physical inactivity. In the occupational setting, obesity was associated with shift work, severe musculoskeletal pain, low influence, but also by good management, fewer role conflicts and a positive work-life balance. Looking only at non-smokers, removed the influence of age and pain. However, non-smokers also had higher depression scores and more role conflicts. Confirming obesity as the strongest risk factor for developing diabetes, the present study identified few occupational risk factors. However, obesity, the key risk factor for diabetes, had a more variable relation with work than did diabetes.

    The global epidemics of type 2 diabetes and obesity have been attributed to the interaction between lifestyle changes and genetic predisposition to these diseases. We compared the prevalences of type 2 diabetes and obesity in Mexican Pima Indians, presumed to have a high genetic predisposition to these diseases, to those in their non-Pima neighbors, both of whom over a 15-year period experienced a transition from a traditional to a more modern lifestyle. Prevalence of diabetes, impaired fasting glucose, impaired glucose tolerance, and obesity in Mexican Pimas (n = 359) and non-Pima Mexicans (n = 251) were determined in 2010 using methods identical to those used in 1995. During this 15-year period, age-adjusted diabetes prevalence was unchanged in Pima men (5.8% in 1995 vs. 6.1% in 2010) yet increased in non-Pima men from 0.0 to 8.6% (P obesity increased significantly in all groups (6.6 vs. 15.7% in Pima men; 8.5 vs. 20.5% in non-Pima men; 18.9. vs 36.3% in Pima women; 29.5 vs. 42.9% in non-Pima women). Type 2 diabetes prevalence increased between 1995 and 2010 in non-Pima men, and to a lesser degree in women of both groups, but it did not increase in Pima men. Prevalence of obesity increased among Pimas and non-Pimas of both sexes. These changes occurred concomitantly with an environmental transition from a traditional to a more modernized lifestyle. © 2015 by the American Diabetes Association.

    Previous studies have shown that circulating adipokines may play an important role in the pathogenesis of some obesity related chronic disease such as dyslipidemia and type2 diabetes mellitus. The aim of the present study was to investigate the association between vaspin, omentin-1 and retinol binding protein-4 levels with metabolic dyslipidemia (MD) criteria in obese and non-obese individuals. The study was conducted on 170 obese and 81 non-obese individuals. After collecting the blood samples, serum levels metabolic parameters as well as three circulating adipokines and body composition were measured. No significant difference was noted regarding the mean serum levels of omentin-1 and vaspin between the obese and non-obese groups, while, serum level of RBP4 was significantly higher in the non-obese group. We found the 0.22 increased risk of MD in obese individuals with higher RBP4 concentration. After the adjustment for confounding factors, this association was still significant. No significant association was noted between MD and its components relative risks with omentin-1 and vaspin levels. Our study demonstrated that circulating RBP4 was significantly higher in the obese individuals which may increase the risk of MD in them. Further researches are needed to address this association.

    Toll-like receptor 4 (TLR4) activation has been proposed to be important for islet cell inflammation and eventually β cell loss in the course of type 1 diabetes (T1D) development. However, according to the “hygiene hypothesis”, bacterial endotoxin lipopolysaccharide (LPS), an agonist on TLR4, inhibits T1D progression. Here we investigated possible mechanisms for the protective effect of LPS on T1D development in non-obese diabetic (NOD) mice. We found that LPS administration to NOD mice during the prediabetic state neither prevented nor reversed insulitis, but delayed the onset and decreased the incidence of diabetes, and that a multiple-injection protocol is more effective than a single LPS intervention. Further, LPS administration suppressed spleen T lymphocyte proliferation, increased the generation of CD4{sup +}CD25{sup +}Foxp3{sup +} regulatory T cells (Tregs), reduced the synthesis of strong Th1 proinflammatory cytokines, and downregulated TLR4 and its downstream MyD88-dependent signaling pathway. Most importantly, multiple injections of LPS induced a potential tolerogenic dendritic cell (DC) subset with low TLR4 expression without influencing the DC phenotype. Explanting DCs from repeated LPS-treated NOD mice into NOD/SCID diabetic mice conferred sustained protective effects against the progression of diabetes in the recipients. Overall, these results suggest that multiple mechanisms are involved in the protective effects of LPS against the development of diabetes in NOD diabetic mice. These include Treg induction, down-regulation of TLR4 and its downstream MyD88-dependent signaling pathway, and the emergence of a potential tolerogenic DC subset. - Highlights: • Administration of lipopolysaccharide (LPS) prevented type 1 diabetes in NOD mice. • Downregulating TLR4 level and MyD88-dependent pathway contributed to protection of LPS. • LPS administration also hampered DC maturation and promoted Treg differentiation.

    Arterial hypertension (AH) and diabetes mellitus (DM) are established cardiovascular risk factors. Impaired glucose homeostasis (IGH; impaired fasting glucose or/and impaired glucose tolerance) or pre-diabetes, obesity, and DM family history identify individuals at risk for type 2 DM in whom preventive interventions are necessary. The aim of this study was to determine the glycemic profile in non-diabetic Greek adult hypertensive men and women according to DM family history and the obesity status. Diabetes family history, obesity markers (waist-to-hip ratio, WHR; body mass index, BMI), glycemic parameters (fasting and 2-hour post-load plasma glucose, if necessary; glycated hemoglobin, HbA1c; fasting insulin), insulin resistance indices (homeostasis model assessment, HOMA; quantitative insulin sensitivity check index, QUICKI; Bennett; McAuley), and IGH prevalence were determined in a large cohort of 11,540 Greek hypertensives referred to our institutions. Positive DM family history was associated with elevated fasting glucose (98.6 ± 13.1 vs 96.5 ± 12.3 mg/dL), HbA1c (5.58% ± 0.49% vs 5.50% ± 0.46%), fasting insulin (9.74 ± 4.20 vs 9.21 ± 3.63 μU/mL) and HOMA (2.43 ± 1.19 vs 2.24 ± 1.01) values, lower QUICKI (0.342 ± 0.025 vs 0.345 ± 0.023), Bennett (0.285 ± 0.081 vs 0.292 ± 0.078) and McAuley (6.73 ± 3.43 vs 6.95 ± 3.44) values, and higher IGH prevalence (45.3% vs 38.7%); P history was significant (P history present with higher IGH prevalence and worse glycemic indices levels compared with those with negative family history, especially in the higher WHR/BMI subgroups.

    Full Text Available Hypertriglyceridemia (HTG is a risk factor for atherosclerotic cardiovascular disease (CVD. We investigated alterations in plasma metabolites associated with borderline-to-moderate HTG (triglycerides (TG 150-500 mg/dL. Using UPLC-LTQ-Orbitrap mass spectrometry analysis, the metabolomics profiles of 111 non-diabetic and non-obese individuals with borderline-to-moderate HTG were compared with those of 111 age- and sex-matched controls with normotriglyceridemia (NTG, TG <150 mg/dL. When compared to the NTG control group, the HTG group exhibited higher plasma levels of lysophosphatidylcholines (lysoPCs, including C14:0 (q = 0.001 and C16:0 (q = 1.8E-05, and several amides, including N-ethyldodecanamide (q = 2.9E-05, N-propyldodecanamide (q = 3.5E-05, palmitoleamide (q = 2.9E-06, and palmitic amide (q = 0.019. The metabolomic profiles of the HTG group also exhibited lower plasma levels of cis-4-octenedioic acid (q<1.0E-9 and docosanamide (q = 0.002 compared with those of the NTG controls. LysoPC 16:0 and palmitoleamide emerged as the primary metabolites able to discriminate the HTG group from the NTG group in a partial least-squares discriminant analysis and were positively associated with the fasting triglyceride levels. We identified alterations in lysoPCs, amides, and cis-4-octenedioic acid among non-diabetic and non-obese individuals with borderline-to-moderate HTG. These results provide novel insights into the metabolic alterations that occur in the early metabolic stages of HTG. This information may facilitate the design of early interventions to prevent disease progression.

    To study the dietary intake and level of physical activity (PA) of patients with diabetes mellitus and the association with non-alcoholic fatty liver disease (NAFLD). Consecutive adult patients with type 2 diabetes mellitus seen in our hospital diabetes clinic were enrolled. The Global Physical Activity Questionnaire and a semi-quantitative food-frequency questionnaire were used to assess PA and dietary intake, respectively. Diagnosis of NAFLD was ultrasound-based and following exclusion of significant alcohol intake and other causes of chronic liver disease. Data for 299 patients were analyzed (mean age 63.3±10.5 years old, 41.1% male). Prevalence of NAFLD was 49.2%. Patients with low PA were more likely to have NAFLD (OR=1.75, 95% CI=1.03-2.99, p=0.029). There was no significant difference in energy intake, intake of macronutrients and percentage energy intake from each macronutrient, high sugar food, high cholesterol food and high SFA food between patients with and without NAFLD. Among centrally obese patients, patients with low PA and in the highest quartile of percentage energy intake from fat (OR=4.03, 95% CI=1.12-15.0, p=0.015), high cholesterol food (OR=3.61, 95% CI=1.37-9.72, p=0.004) and high SFA food (OR=2.67, 95% CI=1.08-6.67, p=0.019) were most likely to have NAFLD. Among those who were not centrally obese, PA and percentage energy intake from fat, high cholesterol food and high SFA food was not associated with NAFLD. Low PA and high percentage energy intake from fat, high cholesterol food and high SFA food is associated with NAFLD in centrally obese but not in non-centrally obese patients with diabetes mellitus.

    To investigate the inter-relationships between adipocytokines, oxidative stress, insulin, Zn and Cu and obesity among Egyptian obese non-diabetic children and adolescents. 72 obese children and adolescents of both sexes (5-17 years) were recruited for the study. 40 healthy normal non-obese persons of matched ages and sexes were used as control group. Lipid profile, tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) and leptin levels were measured. Malondialdehyde (MDA) and reduced glutathione (GSH) concentrations and superoxide dismutase (SOD) activity were estimated. Micronutrients (Zn and Cu) concentrations in addition to insulin and fasting blood sugar (FBS) levels were also evaluated. Estimation of insulin resistance (homeostatic model assessment (HOMA-IR)) was derived from FBS measurements. Significant elevations (Pobese individuals as compared with control group. Insulin and triglyceride levels were significantly increased in obese male children and HDL-cholesterol level was increased significantly in obese adolescent females compared to controls. However, total cholesterol and LDL-cholesterol levels were significantly high in all obese cases as compared with controls. Insulin resistance was detected in 100% of the patients. We concluded that obesity with pro-inflammatory adipocytokines and hypozincemia together by many mechanisms participate in excessive oxidative stress and are highly associated with inflammation and the development of obesity-related complications.

    Bariatric surgery has been effective in treating type 2 diabetes mellitus (T2DM); it has not been used frequently in obese patients with type 1 diabetes mellitus (T1DM). This is the first case series reporting on the effect of bariatric surgery on diabetes control in adolescents with T1DM. Patient A is a 19-year-old obese man with T1DM who underwent vertical sleeve gastrectomy. At 12 months after surgery he demonstrated 28% reduction in BMI. His daily total insulin requirement had decreased; however, hemoglobin A1c remained primarily unchanged at 8.8%. Patient B is a 13-year-old obese girl with an initial clinical diagnosis of T2DM controlled on only metformin. She underwent Roux-en-Y gastric bypass; at 1 month after surgery she presented in diabetic ketoacidosis and was found to have positive islet cell antibodies, which were also present before surgery. Her diagnosis was revised to T1DM, and she was started on insulin. By 28 months after surgery her BMI had decreased by 42%. Since initiation of insulin, her daily total insulin requirement had decreased, but hemoglobin A1c had significantly worsened from 6.3% to 10%. We found that despite significant weight loss, improvements in cardiovascular risk factors (dyslipidemia and obstructive sleep apnea), and quality of life in our patients, bariatric surgery does not necessarily lead to improved glycemic control of T1DM. Patients with T1DM have ongoing dependency on exogenous insulin, and optimal glycemic control still depends on patient compliance with diabetes care.

  2. Detection of molecular paths associated with insulitis and type 1 diabetes in non-obese diabetic mouse.

    Erno Lindfors

    Full Text Available Recent clinical evidence suggests important role of lipid and amino acid metabolism in early pre-autoimmune stages of type 1 diabetes pathogenesis. We study the molecular paths associated with the incidence of insulitis and type 1 diabetes in the Non-Obese Diabetic (NOD mouse model using available gene expression data from the pancreatic tissue from young pre-diabetic mice. We apply a graph-theoretic approach by using a modified color coding algorithm to detect optimal molecular paths associated with specific phenotypes in an integrated biological network encompassing heterogeneous interaction data types. In agreement with our recent clinical findings, we identified a path downregulated in early insulitis involving dihydroxyacetone phosphate acyltransferase (DHAPAT, a key regulator of ether phospholipid synthesis. The pathway involving serine/threonine-protein phosphatase (PP2A, an upstream regulator of lipid metabolism and insulin secretion, was found upregulated in early insulitis. Our findings provide further evidence for an important role of lipid metabolism in early stages of type 1 diabetes pathogenesis, as well as suggest that such dysregulation of lipids and related increased oxidative stress can be tracked to beta cells.

    Full Text Available BACKGROUND: Obesity is highly related to insulin resistance, therefore, the increased number of obesity is followed by the increased prevalence of type 2 Diabetes Melitus. Obesity is associated with increased of reactive oxygen species (ROS in muscle, liver and endothelial cells. The increase of ROS would lead to insulin resistance (IR and increased pro-inflammatory protein. FFA plays an important role in IR by inhibiting muscle glucose transport and oxidation via effects on serine/threonine phosphorylation of IRS-1. The aim of this study was discover the existence of SOD, hs-CRP and and adiponectin levels towards the occurrence of insulin resistance which was caused by elevated level of FFA and to discover the interaction between SOD, hs-CRP and adiponectin in non diabetic obese adult male. METHODS: This was observational study with cross sectional design. There were 65 obese male non diabetic subjects and 45 non obese male non diabetic subjects who met the criteria. In this study, measurements were done on body mass index (BMI, fasting glucose, insulin, adiponectin, hs-CRP and SOD. Obese was defined as BMI >25 kg/m2, normal weight was defined as BMI 18.5-23 kh/m2 and Insulin Resistance was defined as HOMA-IR >1. RESULTS: This study showed that Hypoadiponectinemia condition, decreased SOD level and high level of hs-CRP is associated with insulin resistance in obese non diabetic subject. Adiponectin and SOD were correlated negatively with insulin resistance in obese non diabetic (Adiponectin, r=-0.455, p<0.001; SOD, r=-0.262, p=0.003, hs-CRP was positively correlated with insulin resistance in obese non diabetic (r=0.592, p<0.001. FFA levels was increased in obese insulin resistance compared with non obese non insulin resistance. The Odds Ratio of Adiponectin, hs-CRP and SOD in this study was analyzed by logistic binary. The OR for SOD 3.6 (p=0.001, hs-CRP 9.1 (p<0.001 and Adiponectin 7.2 (p<0.001. CONCLUSIONS: This study suggested that FFA

    Metabolic disorders, such as diabetes and obesity, have been indicated to disturb the function of the central nervous system (CNS) as well as several peripheral organs. Clinically, it is well recognized that the prevalence of anxiety and depression is higher in diabetic and obesity patients than in the general population. We have recently indicated that streptozotocin-induced diabetic and diet-induced obesity mice have enhanced fear memory and higher anxiety-like behavior in several tests such as the conditioned fear, tail-suspension, hole-board and elevated open-platform tests. The changes in fear memory and anxiety-like behavior of diabetic and obese mice are due to the dysfunction of central glutamatergic and monoaminergic systems, which is mediated by the changes of intracellular signaling. These results suggest that metabolic disorders strongly affect the function of the CNS and disturb the higher brain functions. These dysfunctions of the CNS in diabetes and obesity are involved in the increased prevalence of anxiety disorders and depression. Normalization of these dysfunctions in the CNS will be a new attractive target to treat the metabolic disorders and their complications.

    Abnormal glucose handling has emerged as a major clinical problem in millions of diabetic patients worldwide. Insulin resistance affects especially one of the main target organs of this hormone, the skeletal musculature, making impaired glucose metabolism in contractile fibres a major feature of type 2 diabetes. High levels of circulating free fatty acids, an increased intramyocellular lipid content, impaired insulin-mediated glucose uptake, diminished mitochondrial functioning and an overall weakened metabolic flexibility are pathobiochemical hallmarks of diabetic skeletal muscles. In order to increase our cellular understanding of the molecular mechanisms that underlie this complex diabetes-associated skeletal muscle pathology, we initiated herein a mass spectrometry-based proteomic analysis of skeletal muscle preparations from the non-obese Goto-Kakizaki rat model of type 2 diabetes. Following staining of high-resolution two-dimensional gels with colloidal Coomassie Blue, 929 protein spots were detected, whereby 21 proteins showed a moderate differential expression pattern. Decreased proteins included carbonic anhydrase, 3-hydroxyisobutyrate dehydrogenase and enolase. Increased proteins were identified as monoglyceride lipase, adenylate kinase, Cu/Zn superoxide dismutase, phosphoglucomutase, aldolase, isocitrate dehydrogenase, cytochrome c oxidase, small heat shock Hsp27/B1, actin and 3-mercaptopyruvate sulfurtransferase. These proteomic findings suggest that the diabetic phenotype is associated with a generally perturbed protein expression pattern, affecting especially glucose, fatty acid, nucleotide and amino acid metabolism, as well as the contractile apparatus, the cellular stress response, the anti-oxidant defense system and detoxification mechanisms. The altered expression levels of distinct skeletal muscle proteins, as documented in this study, might be helpful for the future establishment of a comprehensive biomarker signature of type 2 diabetes

    Full Text Available OBJECTIVE: Type 2 diabetes (T2DM and obesity are associated with magnesium deficiency. We aimed to determine whether the presence of type 2 diabetes and the degree of metabolic control are related to low serum magnesium levels in obese individuals. METHODS: A Case-control study: 200 obese subjects [50 with T2DM (cases and 150 without diabetes (controls] prospectively recruited. B Interventional study: the effect of bariatric surgery on serum magnesium levels was examined in a subset of 120 obese subjects (40 with type 2 diabetes and 80 without diabetes. RESULTS: Type 2 diabetic patients showed lower serum magnesium levels [0.75±0.07 vs. 0.81±0.06 mmol/L; mean difference -0.06 (95% CI -0.09 to -0.04; p<0.001] than non-diabetic patients. Forty-eight percent of diabetic subjects, but only 15% of non-diabetic subjects showed a serum magnesium concentration lower than 0.75 mmol/L. Significant negative correlations between magnesium and fasting plasma glucose, HbA1c, HOMA-IR, and BMI were detected. Multiple linear regression analysis showed that fasting plasma glucose and HbA1c independently predicted serum magnesium. After bariatric surgery serum magnesium increased only in those patients in whom diabetes was resolved, but remain unchanged in those who not, without difference in loss weight between groups. Changes in serum magnesium negatively correlated with changes in fasting plasma glucose and HbA1c. Absolute changes in HbA1c independently predicted magnesium changes in the multiple linear regression analysis. CONCLUSIONS: Our results provide evidence that the presence of diabetes and the degree of metabolic control are essential in accounting for the lower levels of magnesium that exist in obese subjects.

    Obesity's association with type 2 diabetes (T2DM) is well established, but is less clear with type 1 diabetes (T1DM). We calculated the prevalence of overweight and obesity among diabetic youth in the USA from a six-center, population-based study of racially and ethnically diverse youth with diabetes, and we compared these rates with estimates among nondiabetic youth. Diabetic participants were examined in 2001-2004 for the SEARCH for Diabetes in Youth study (SEARCH) and nondiabetic participants were examined during the same years of the National Health and Nutrition Examination Survey (NHANES). 3953 diabetic youth and 7666 nondiabetic youth aged 3-19 yr. Overweight was defined as body mass index (BMI) from the 85th to obesity defined as > or = 95th percentile. Diabetes type was categorized as T1DM or T2DM based on physician diagnosis. Among youth with T2DM, the prevalence of overweight was 10.4% and obesity was 79.4%. Among youth with T1DM, 22.1% were overweight. The prevalence of overweight among youth with T1DM was higher than among those without diabetes overall (22.1% vs. 16.1%) (P obesity rate for T1DM was 12.6% overall (range Non-Hispanic White 10.7%-African-American 20.1%). As expected, most of the youth with T2DM were obese. Youth with T1DM had a higher prevalence of overweight, but not of obesity, than nondiabetic youth. Future studies of obesity among youth with diabetes of all types will further our understanding of the impact of obesity on diabetes both as a risk factor and a comorbidity.

    Levels of tissue iron contribute to determining diabetes risk, but little is known about the effects of higher iron levels on weight, and on the interaction of weight and iron overload on diabetes risk. Therefore, the effect of iron on body mass index and diabetes in individuals with iron overload from hereditary hemochromatosis (HH), compared to non-HH siblings and historical controls was examined. Chart reviews were performed on a cohort of adults (age ≥40, N = 101) with the common C282Y/C282Y HFE genotype, compared to wild type siblings (N = 32) and comparable NHANES cohorts, with respect to body mass index and diabetes status. Males with HH have lower body mass index (BMI) than control siblings. Females had a trend toward decreased BMI that was not significant, possibly related to decreased degrees of iron overload. In both males and females, increased rates of diabetes were seen, especially in the overweight or obese. High tissue iron levels may be both pro- and anti-diabetic. The prevalence of obesity and diabetes in HH is likely dependent upon the degree of iron overload, caloric intake, and other genetic and environmental factors, contributing to the observed heterogeneity in the frequency of disease-related morbidities in HH.

    Severe obesity is the fastest growing subgroup of obesity in youth. We sought to explore the association between severe obesity and subclinical measures of cardiac and vascular structure and function in adolescents and young adults. This was a cross-sectional comparison of 265 adolescents and young adults with severe obesity (defined as body mass index [BMI] ≥120% of the 95th percentile) to 182 adolescents and young adults with obesity (defined as BMI ≥100-119th of the 95th percentile) at tertiary medical center. Noninvasive measures of cardiac and vascular structure and function were assessed. Participants were a mean age of 17.9 years, 62% were non-Caucasian, and 68% were female. Systolic blood pressure, fasting insulin, C-reactive protein, IL-6, and frequency of type 2 diabetes were higher in participants with severe obesity (all P obesity as measured by higher left ventricular mass index, worse diastolic function, higher carotid intima media thickness, and pulse wave velocity and lower brachial distensibility (all P obesity (compared with obesity) was independently associated with each of the above outcomes after adjustment for age, race, sex, blood pressure, lipids, and inflammatory markers (P young adults with severe obesity have a more adverse cardiovascular risk profile and worse cardiac and vascular structure and function. More importantly, severe obesity is independently associated with these subclinical cardiac and vascular changes.

    Activation of the cholinergic anti-inflammatory pathway (CAP) has been shown to reduce inflammation in animal models, while abrogation of the pathway increases inflammation. We investigated whether modulation of CAP influences inflammation in the non-obese diabetic (NOD) mouse model for Sjögren's syndrome and type 1 diabetes. The alpha-7 nicotinic acetylcholine receptor (α7nAChR) was stimulated with AR-R17779 or nicotine in NOD mice. In a second study, unilateral cervical vagotomy was performed. α7nAChR expression, focus scores, and salivary flow were evaluated in salivary glands (SG) and insulitis score in the pancreas. Cytokines were measured in serum and SG. α7nAChR was expressed on myoepithelial cells in SG. Monocyte chemotactic protein-1 levels were reduced in SG after AR-R17779 treatment and tumor necrosis factor production was increased in the SG of the vagotomy group compared to controls. Focus score and salivary flow were unaffected. NOD mice developed diabetes more rapidly after vagotomy, but at completion of the study there were no statistically significant differences in number of mice that developed diabetes or in insulitis scores. Intervention of the CAP in NOD mice leads to minimal changes in inflammatory cytokines, but did not affect overall inflammation and function of SG or development of diabetes. © 2015 John Wiley & Sons A/S.

    individuals. The objective was to examine the effect of male overweight/obesity and type 2 diabetes mellitus (T2DM) on associations between adiposity parameters and sCD163. A total of 23 overweight/obese non-diabetic men, 16 overweight/obese men with T2DM, and a control group of 20 normal-weight healthy men...... multiple linear regression analysis. In the normal-weight healthy men, there was no significant association between adiposity parameters and sCD163, whereas in the overweight/obese non-diabetic men, measures of general and regional adiposity were positively associated with sCD163. In the overweight/obese......-body fat, adjusted for BMI and age, VAT remained a significant predictor of sCD163 in the overweight/obese T2DM men, but not in the overweight/obese non-diabetic men. Our results indicate that VAT inflammation is exaggerated in men with T2DM, and that propensity to store excess body fat viscerally...

    Insulin resistance is a major component of metabolic syndrome, type 2 Diabetes Mellitus (T2DM) and coronary artery disease (CAD). Although important in T2DM, its role as a predictor of CAD in non-diabetic patients is less studied. In the present study, we aimed to evaluate the association of HOMA-IR with significant CAD, determined by coronary angiography in non-obese, non-T2DM patients. We also evaluate the association between 3 oral glucose tolerance test (OGTT) based insulin sensitivity indexes (Matsuda, STUMVOLL-ISI and OGIS) and CAD. We conducted a cross-sectional study with 54 non-obese, non-diabetic individuals referred for coronary angiography due to suspected CAD. CAD was classified as the "anatomic burden score" corresponding to any stenosis equal or larger than 50 % in diameter on the coronary distribution. Patients without lesions were included in No-CAD group. Patients with at least 1 lesion were included in the CAD group. A 75 g oral glucose tolerance test (OGTT) with measurements of plasma glucose and serum insulin at 0, 30, 60, 90 and 120 min was obtained to calculate insulin sensitivity parameters. HOMA-IR results were ranked and patients were also categorized into insulin resistant (IR) or non-insulin resistant (NIR) if they were respectively above or below the 75th percentile (HOMA-IR > 4.21). The insulin sensitivity tests results were also divided into IR and NIR, respectively below and above each 25th percentile. Chi square was used to study association. Poisson Regression Model was used to compare prevalence ratios between categorized CAD and IR groups. Fifty-four patients were included in the study. There were 26 patients (48 %) with significant CAD. The presence of clinically significant CAD was significant associated with HOMA-IR above p75 (Chi square 4.103, p = 0.0428) and 71 % of patients with HOMA-IR above p75 had significant CAD. Subjects with CAD had increased prevalence ratio of HOMA-IR above p75 compared to subjects without

    We have previously reported that a high-fat, carbohydrate-free diet prevents diabetes and beta-cell destruction in the New Zealand Obese (NZO) mouse strain. Here we investigated the effect of diets with and without carbohydrates on obesity and development of beta-cell failure in a second mouse model of type 2 diabetes, the db/db mouse. When kept on a carbohydrate-containing standard (SD; with (w/w) 5.1, 58.3, and 17.6% fat, carbohydrates and protein, respectively) or high-fat diet (HFD; 14.6, 46.7 and 17.1%), db/db mice developed severe diabetes (blood glucose >20 mmol/l, weight loss, polydipsia and polyurea) associated with a selective loss of pancreatic beta-cells, reduced GLUT2 expression in the remaining beta-cells, and reduced plasma insulin levels. In contrast, db/db mice kept on a high-fat, carbohydrate-free diet (CFD; with 30.2 and 26.4% (w/w) fat or protein) did not develop diabetes and exhibited near-normal, hyperplastic islets in spite of a morbid obesity (fat content >60%) associated with hyperinsulinaemia. These data indicate that in genetically different mouse models of obesity-associated diabetes, obesity and dietary fat are not sufficient, and dietary carbohydrates are required, for beta-cell destruction.

    Fenbendazole (FBZ) is a common, highly efficacious broad-spectrum anthelmintic drug used to treat and limit rodent pinworm infections. However, the effect of its prophylactic use on the immune response of rodents is largely undefined. The non-obese diabetic (NOD) mouse is a model commonly used to study type 1 diabetes (T1D). Parasitic infections will inhibit diabetes development in NOD mice; thus, in the presence of contamination, prophylactic treatment with anthelmintics must be considered to maintain experimental research. Herein, we investigated the prophylactic use of FBZ in NOD mice to determine its effect on the incidence and onset of diabetes, lymphocyte sub-populations and T cell proliferative responses. NOD mice were separated into control and treatment groups. The treatment group received a diet containing FBZ. Animals were monitored for the incidence and onset of T1D. At matched time points, diabetic and non-diabetic mice were killed and splenic lymphocytes analyzed for various cell sub-populations and mitogen-induced proliferative responses using flow cytometry. Treated and control mice were monitored >23 weeks with no detectable effects on the incidence or onset of diabetes. Moreover, no significant differences were detected in lymphocyte sub-populations and mitogen-induced CD4(+) and CD8(+) proliferative responses between control and treatment groups. These results suggest that prophylactic FBZ treatment does not significantly alter the incidence or onset of diabetes in NOD mice. The prophylactic use of FBZ, therefore, presents a viable approach for the prevention of pinworm infection in precious experimental animals with substantial scientific and economic benefits.

    There are insufficient data regarding the changes in adipokine levels after laparoscopic adjustable gastric banding (LAGB) in diabetic and non-diabetic patients and their effects on insulin resistance and type 2 diabetes remission. To assess leptin, adiponectin, and insulin resistance changes after LAGB in diabetic and non-diabetic morbidly obese patients. One hundred and three patients (37 with and 66 without type 2 diabetes) underwent LAGB from January 2009 to January 2010. Glycated hemoglobin, insulin, adipokine levels and insulin resistance were evaluated preoperatively, and 1 and 4 years after LAGB. The mean patient age was 45.9 ±11.7 years and mean preoperative body mass index was 47.5 ±7.3 kg/m 2 . A total of 80 of 103 patients (77.6%) completed the 4-year follow-up. After 4 years the mean excess weight loss was 38.8% and 39.5% in diabetic and non-diabetic patients respectively. Leptin levels decreased significantly in both groups at 1 year, but after 4 years this was noted only in non-diabetic patients. After 1 year adiponectin levels increased significantly only in non-diabetic patients (p = 0.003) and remained almost the same at 4 years. A significant decrease in insulin resistance was noted in both groups 1 year after LAGB and diabetes remission was observed in 23 (62.1%) patients. There was a negative correlation between preoperative insulin resistance and adiponectin levels throughout the follow-up period. Leptin levels positively correlated with BMI throughout the study period (baseline r = 0.45; p < 0.001; after 1 year r = 0.71; p < 0.001; after 4 years r = 0.68; p < 0.001). There was no significant correlation between leptin and adiponectin concentrations preoperatively or after 1 year; however, at 4 years it was significant (r = 0.27; p < 0.02). The most significant metabolic changes occurred within 1 year after LAGB. The 4-year follow-up revealed stabilization in metabolic indices rather than significant improvement.

Here, we show that antigen-specific Tregs can also be induced in an antigen-specific setting in vitro. Treatment of non-obese diabetic (NOD female mice between 9-12 weeks of age with a short course of BsB elicited a transient increase of Tregs in the blood and moderately delayed the onset of autoimmune type 1 diabetes (T1D. However, a longer course of treatment (10 weeks of 4-13 weeks-old female NOD animals with BsB significantly delayed the onset of disease or protected animals from developing diabetes, with only 13% of treated animals developing diabetes by 35 weeks of age compared to 80% of the animals in the control group. Histopathological analysis of the pancreata of the BsB-treated mice that remained non-diabetic revealed the preservation of insulin-producing β-cells despite the presence of different degrees of insulitis. Thus, a bifunctional protein capable of engaging CTLA-4 and MHCII and indirectly co-ligating CTLA-4 to the TCR protected NOD mice from developing T1D.

    Obesity and type 2 diabetes mellitus (T2DM) result from sedentary lifestyle, high-carbohydrate diets and genetic predisposition. Epigenetics is a form of genetic regulation in specialized cells that does not involve changes in the deoxyribonucleic acid (DNA) sequence, but it can be inherited to one or more generations through mitosis or meiosis. Children whose mothers develop gestational diabetes are more likely to become obese and diabetic in adult life. DNA methylation is a major mechanism in the regulation of transcription and gene expression of several genes. High levels of glucose and insulin during pregnancy modify the risk of developing T2DM, suggesting that the expression pattern is modified due to cell memory in a specific tissue. If T2DM is linked to adaptation in utero, the obvious primary prevention is to protect the fetal development. Future epidemiological studies need to employ more accurate indicators or markers of development to show the relationship between a specific disease and the exposure to environmental factors. The mechanisms by which malnutrition, and intrauterine growth retardation produce changes in the metabolism of glucose and insuline are worth to explore in order to control obesity and T2DM.

    Oxidative stress occurs due to delicate imbalance between pro-oxidant and anti oxidant forces in our system. It has been found to be associated with many morbidities but its association with obesity and insulin resistance is still controversial. Here in our study we examined 167 patients of recent onset type 2 diabetes mellitus and 60 age sex matched non-diabetic control. Body Mass Index (BMI), abdominal circumference, fasting blood glucose, serum insulin and plasma Malondealdehyde (MDA, marker for oxidative stress) were measured in them. On the basis of BMI, subjects were divided into obese (BMI≥25) and non obese (BMIobese and non-obese sub groups. Insulin resistance score showed positive correlation with BMI, abdominal circumference, and plasma MDA, strength of association being highest with abdominal circumference. Plasma MDA was found to have positive correlation with physical parameters. Study concludes that, obesity mainly central type may predispose to insulin resistance and oxidative stress may be a crucial factor in its pathogenesis. Thus, oxidative stress may be the connecting link between obesity and type 2 diabetes mellitus, two on going global epidemics.

    To determine whether fat free mass (FFM) is independently associated with the metabolically healthy obesity (MHO) phenotype, the metabolic syndrome (MS), and type 2 diabetes (T2D) in obese Asian adults. Obese patients (body mass index [BMI] ≥25 kg/m 2 ) seeking weight management at an academic medical center from 2007 to 2016 were included. FFM was measured by bioelectrical impedance. Of the 552 patients (67.0% female, median age 40.5 years, median BMI 38.3 kg/m 2 ), MHO was present in 19%, MS in 55.4%, and T2D in 32.6%. In multivariate models, higher fat-free mass index (FFMI) was independently associated with the metabolically abnormal obesity (MAO) phenotype, (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.09-1.37), and increased risk of MS (OR 1.12, 95% CI 1.03-1.22) in women but not in men. Older age was independently associated with the MAO phenotype (OR 1.06, 95% CI 1.04-1.09 in women; OR 1.06, 95% CI 1.02-1.09 in men), MS (OR 1.05, 95% CI 1.03-1.06 in women; OR 1.05, 95% CI 1.02-1.07 in men), and T2D (OR 1.07, 95% CI 1.05-1.09 in women; OR 1.06, 95% CI 1.04-1.09 in men). Waist-hip ratio was independently associated with the MAO phenotype in men (OR 1.08, 95% CI 1.01-1.15), while waist circumference was associated with T2D in women (OR 1.03, 95% CI 1.01-1.05). Older age, central fat distribution, and-in contrast to previous findings-an increase in FFMI among women were independent predictors of adverse metabolic health in this cohort of middle-aged obese Asian adults. Further studies are required to elucidate underlying mechanisms and therapeutic implications of these findings.

    Full Text Available Abstract Background Obesity is a state of chronic low-grade inflammation. Chronic low-grade inflammation is associated with the pathophysiology of both type-2 diabetes and atherosclerosis. Prevention or reduction of chronic low-grade inflammation may be advantageous in relation to obesity related co-morbidity. In this study we investigated the acute effect of dietary protein sources on postprandial low-grade inflammatory markers after a high-fat meal in obese non-diabetic subjects. Methods We conducted a randomized, acute clinical intervention study in a crossover design. We supplemented a fat rich mixed meal with one of four dietary proteins - cod protein, whey isolate, gluten or casein. 11 obese non-diabetic subjects (age: 40-68, BMI: 30.3-42.0 kg/m2 participated and blood samples were drawn in the 4 h postprandial period. Adiponectin was estimated by ELISA methods and cytokines were analyzed by multiplex assay. Results MCP-1 and CCL5/RANTES displayed significant postprandial dynamics. CCL5/RANTES initially increased after all meals, but overall CCL5/RANTES incremental area under the curve (iAUC was significantly lower after the whey meal compared with the cod and casein meals (P = 0.0053. MCP-1 was initially suppressed after all protein meals. However, the iAUC was significantly higher after whey meal compared to the cod and gluten meals (P = 0.04. Conclusion We have demonstrated acute differential effects on postprandial low grade inflammation of four dietary proteins in obese non-diabetic subjects. CCL5/RANTES initially increased after all meals but the smallest overall postprandial increase was observed after the whey meal. MCP-1 was initially suppressed after all 4 protein meals and the whey meal caused the smallest overall postprandial suppression. Trial Registration ClinicalTrials.gov ID: NCT00863564

    To compare the metabolic characteristics of obese and non-obese young women with polycystic ovary syndrome (POS) from the Brazilian Southeast. This was a cross-sectional study conducted on 218 women of reproductive age with a diagnosis of POS--90 non-obese women (BMI between 18.5 and 29.9 kg/m²), and 128 obese patients (BMI > 30 kg/m²) selected at the time of diagnosis. The frequency of insulin resistance (IR), glucose intolerance (GI), metabolic syndrome (MetS) and type 2 diabetes mellitus (DM2) and mean values of total cholesterol (TC), triglycerides (TG), high-density (HDL) and low-density lipoproteins (LDL), were compared between obese and non-obese patients with POS. The two groups were also compared in terms of clinical and hormonal characteristics (follicle stimulating hormone, prolactin, thyroid stimulating hormone, total testosterone, dihydroepiandrostenedione sulfate, and 17-hydroxyprogesterone). Statistical analysis was performed using the SAS 9.0 software. Quantitative variables were compared by the Student's t-test (data with normal distribution) or by the Mann-Whitney test (non-parametric distribution). Qualitative variables were compared by the Fisher test. The level of significance was set at 5% (p women with POS have a higher frequency of IR, GI and MS than non-obese. However, the occurrence of metabolic disorders is elevated also in the non-obese patients, suggesting that the presence of the syndrome may favor the development of metabolic comorbidities with potential medium- and long-term repercussions.

    Andrographis paniculata is an annual herb and widely cultivated in Southeast Asian countries for its medicinal use. In recent investigations, A. paniculata was found to be effective against Type 1 diabetes mellitus (Type 1 DM). Here, we used a non-genetic out-bred Sprague-Dawley rat model to test the antidiabetic activity of A. paniculata against Type 2 diabetes mellitus (Type 2 DM). Proton Nuclear Magnetic Resonance (¹H-NMR) spectroscopy in combination with multivariate data analyses was used to evaluate the A. paniculata and metformin induced metabolic effects on the obese and obese-diabetic (obdb) rat models. Compared to the normal rats, high levels of creatinine, lactate, and allantoin were found in the urine of obese rats, whereas, obese-diabetic rats were marked by high glucose, choline and taurine levels, and low lactate, formate, creatinine, citrate, 2-oxoglutarate, succinate, dimethylamine, acetoacetate, acetate, allantoin and hippurate levels. Treatment of A. paniculata leaf water extract was found to be quite effective in restoring the disturbed metabolic profile of obdb rats back towards normal conditions. Thisstudy shows the anti-diabetic potential of A. paniculata plant extract and strengthens the idea of using this plant against the diabetes. Further classical genetic methods and state of the art molecular techniques could provide insights into the molecular mechanisms involved in the pathogenesis of diabetes mellitus and anti-diabetic effects of A. paniculata water extract.

    Full Text Available Tolerogenic DCs (tolDCs are being researched as a promising intervention strategy also in autoimmune diseases including type 1 diabetes (T1D. T1D is a T-cell-mediated, organ-specific disease with several well-defined and rather specific autoantigens, i.e., proinsulin, insulin, glutamic acid decarboxylase 65 (GAD65, that have been used in animal as well as human intervention trials in attempts to achieve a more efficient, specific immunotherapy. In this study, we have tested tolerogenic DCs for their effectiveness to prevent adoptive transfer of diabetes by diabetogenic splenocytes into non-obese diabetes (NOD-severe combined immunodeficiency (NOD-SCID recipients. While i.p. application of tolDCs prepared from bone marrow of prediabetic NOD mice by vitamin D2 and dexamethasone significantly reduced diabetes transfer into the NOD-SCID females, this effect was completely abolished when tolDCs were loaded with the mouse recombinant GAD65, but also with a control protein—ovalbumin (OVA. The effect was not dependent on the presence of serum in the tolDC culture. Similar results were observed in NOD mice. Removal of possible bystander antigen-presenting cells within the diabetogenic splenocytes by negative magnetic sorting of T cells did not alter this surprising effect. Tolerogenic DCs loaded with an immunodominant mouse GAD65 peptide also displayed diminished diabetes-preventive effect. Tolerogenic DCs were characterized by surface maturation markers (CD40, CD80, CD86, MHC II and the lipopolysaccharide stability test. Data from alloreactive T cell proliferation and cytokine induction assays (IFN-γ did not reveal the differences observed in the diabetes incidence. Migration of tolDCs, tolDCs-GAD65 and tolDCs-OVA to spleen, mesenteric- and pancreatic lymph nodes displayed similar, mucosal pattern with highest accumulation in pancreatic lymph nodes present up to 9 days after the i.p. application. These data document that mechanisms by which tol

    Type 2 diabetes (T2D) and obesity are the major public health problems. Substantial efforts have been made to define loci and variants contributing to the individual risk of these disorders. However, the overall risk explained by genetic variation is very modest. Epigenetics is one of the fastest growing research areas in biomedicine as changes in the epigenome are involved in many biological processes, impact on the risk for several complex diseases including diabetes and may explain susceptibility. In this review, we focus on the role of DNA methylation in contributing to the risk of T2D and obesity.

    Non-obese diabetic (NOD) mice provide a model for type 1 diabetes mellitus. We previously showed that allogeneic bone marrow transplantation (ABMT) can prevent and treat insulitis and overt diabetes in NOD mice. However, ABMT alone could not be used to treat overt diabetes in NOD mice whose islets had been completely destroyed. To provide insulin-producing cells, pancreatic tissue from newborn mice was grafted under the renal capsules in combination with ABMT. The aims of concomitant ABMT are as follows. (i) It induces immunological tolerance to the donor-type major histocompatibility complex determinants and permits the host to accept subsequent pancreatic allografts from the bone marrow donor. (ii) ABMT replaces abnormal stem cells with normal stem cells. After transplantation of bone marrow plus newborn pancreas, NOD mice showed reduction of the glycosuria and a normal response in the glucose-tolerance test. Immunohistological study revealed the presence of clustered insulin-containing beta cells in the grafted pancreatic transplants. ABMT may become a viable treatment of established type 1 diabetes mellitus in humans

    Full Text Available The aim of this study was to evaluate the association between the family history (FH of type 2 diabetes and metabolic syndrome (MetS in a group of non-diabetic obese female subjects. A cross-sectional study was conducted in 239 female patients with obesity, regularly attending the Internal Medicine Division’s outpatient clinic (Hospital de Clínicas de Porto Alegre, Brazil. The inclusion criteria were patients with body mass index ?30 kg/m2 and absence of type 2 diabetes. The FH was considered positive if a first degree relative had a diagnosis of diabetes. Seventy-four of 239 patients evaluated (30% had a positive FH for type 2 diabetes. Patients with positive FH had higher waist/hip ratio and MetS more often than patients with negative FH. FH of type 2 diabetes was associated with MetS in this sample of non-diabetic obese female patients. Waist/hip ratio and fasting plasma glucose, markers of insulin resistance, were also associated with FH of type 2 diabetes. The simple question: “Do you have a FH of type 2 diabetes?” may help to identify the obese patients that should be better evaluated and intensively treated with the objective of preventing type 2 diabetes.

    Obesity and insulin resistance are associated with classic and new cardiovascular risk factors, such as inflammatory markers and adipocytokines. The aim of this study was to examine whether weight reduction could change visfatin serum concentrations in obese patients. This was an interventional longitudinal study analyzing a population of 80 obese non-diabetic outpatients. Weight, blood pressure, fasting serum glucose, C-reactive protein, plasma insulin, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triacylglycerols, and insulin resistance (homeostatic model assessment) were measured before and after 3 mo on a hypocaloric diet. Eighty patients were enrolled. The mean age was 46.7 +/- 16.7 y, the mean body mass index was 34.1 +/- 4.8 kg/m(2), with 20 men (25%) and 60 women (75%). After 3 mo on a hypocaloric diet, body mass index, fat mass, waist circumference, systolic blood pressure, fasting serum glucose, total cholesterol, and low-density lipoprotein cholesterol decreased. The serum concentration of visfatin decreased with weight loss (112.14 +/- 70.2 versus 99.4 +/- 58.1 ng/mL, P hypocaloric diet is associated with a significant decrease in circulating serum concentrations of the novel adipokine visfatin in obese subjects. Visfatin is inversely correlated with age.

    This article focuses on (a) identifying obesity and other risk factors for developing type 2 diabetes, (b) differentiating between pediatric type 1 diabetes and type 2 diabetes, and (c) treating pediatric type 2 diabetes. Obesity has significant implications on a child's health, including an increased risk for insulin resistance and progression to type 2 diabetes. Type 2 diabetes in children, characterized by insulin resistance and relative pancreatic b-cell failure due to the increased demand for insulin production, has now reached epidemic proportions. Longitudinal research on pediatric type 2 diabetes, however, is lacking because this epidemic is relatively new. Treatment of type 2 diabetes in children is focused on lifestyle modification with weight management/increased physical activity, and pharmacological management through oral medication or insulin therapy. Because children with type 2 diabetes are at risk for developing diabetes-related complications earlier in life, they need to be closely monitored for comorbidities.

    Metabolic syndrome and osteoporosis share similar risk factors. Also, patients with diabetes have a higher risk of osteoporosis and fracture. Liver manifestations, such as non-alcoholic steatohepatitis (NASH), of metabolic syndrome are further aggravated in diabetics and often lead to liver failure. Our objective was to create a rat model of human metabolic syndrome and determine the long-term impact of early-onset T1D on bone structure and strength in obese growing rats. Male rats were given either standard chow and RO water (Controls) or a high-fat, high-cholesterol diet and sugar water containing 55% fructose and 45% glucose (HFD). A third group of rats received the HFD diet and a single dose of streptozotocin to induce type 1 diabetes (HFD/Sz). Body weight and glucose tolerance tests were conducted several times during the course of the study. Serum chemistry, liver enzymes, and biomarkers of bone metabolism were evaluated at 10 and 28 weeks. Shear wave elastography and histology were used to assess liver fibrosis. Cancellous bone structure and cortical bone geometry were evaluated by mCT and strength by the 3-point bending method. Body mass and fat accumulation was significantly higher in HFD and HFD/Sz rats compared to Controls. Rats in both the HFD and HFD/Sz groups developed NASH, although the change was more severe in diabetic rats. Although both groups of obese rats had larger bones, their cancellous structure and cortical thickness were reduced, resulting in diminished strength that was further aggravated by diabetes. The HFD and HFD/Sz rats recapitulate MeSy in humans with liver pathology consistent with NASH. Our data provide strong indication that obesity accompanied by type 1 diabetes significantly aggravates comorbidities of MeSy, including the development of osteopenia and weaker bones. The juvenile rat skeleton seems to be more vulnerable to damage imposed by obesity and diabetes and may offer a model to inform the underlying pathology associated

In obese individuals, the amount of nonesterified fatty acids, glycerol, hormones, cytokines, proinflammatory markers, and other substances that are involved in the development of insulin resistance, is increased. The pathogenesis in the development of diabetes is based on the fact that the β-islet cells of the pancreas are impaired, causing a lack of control of blood glucose. The development of diabetes becomes more inevitable if the failure of β-islet cells of the pancreas is accompanied by insulin resistance. Weight gain and body mass are central to the formation and rising incidence of type 1 and type 2 diabetes. This literature review will demonstrate the facts that link obesity with insulin resistance and pancreatic β-cell dysfunction. In conclusion, new approaches in managing and preventing diabetes in obese individuals must be studied and investigated based on the facts. Keywords: diabetes mellitus, obesity, insulin resistance

    We seek to observe the association between childhood obesity by different measures and adult obesity, metabolic syndrome (MetS), and diabetes. Thousand two hundred and nine subjects from "Beijing Blood Pressure Cohort Study" were followed 22.9 ± 0.5 years in average from childhood to adulthood. We defined childhood obesity using body mass index (BMI) or left subscapular skinfold (LSSF), and adult obesity as BMI ≥ 28 kg/m(2). MetS was defined according to the joint statement of International Diabetes Federation and American Heart Association with modified waist circumference (≥ 90/85 cm for men/women). Diabetes was defined as fasting plasma glucose ≥ 7.0 mmol/L or blood glucose 2 h after oral glucose tolerance test ≥ 11.1 mmol/L or currently using blood glucose-lowering agents. Multiple linear and logistic regression models were used to assess the association. The incidence of adult obesity was 13.4, 60.0, 48.3, and 65.1 % for children without obesity, having obesity by BMI only, by LSSF only, and by both, respectively. Compared to children without obesity, children obese by LSSF only or by both had higher risk of diabetes. After controlling for adult obesity, childhood obesity predicted independently long-term risks of diabetes (odds ratio 2.8, 95 % confidence interval 1.2-6.3) or abdominal obesity (2.7, 1.6-4.7) other than MetS as a whole (1.2, 0.6-2.4). Childhood obesity predicts long-term risk of adult diabetes, and the effect is independent of adult obesity. LSSF is better than BMI in predicting adult diabetes.

    A young obese man with ketoacidosis-onset type 2 diabetes mellitus, associated with severe hypertriglyceridemia, was admitted to a local hospital complaining of abdominal pain. Although the abdominal pain worsened, his serum amylase level remained normal with persistent severe hypertriglyceridemia until the second day of hospitalization. The next day, computed tomography showed severe acute pancreatitis (AP) with serum amylase elevation, while the patient's triglyceride level decreased to 558 mg/dL. He was transferred to our hospital and recovered after intensive care. AP accompanied by diabetic ketoacidosis is not rare but an early diagnosis can be difficult to make due to normal amylase levels in the presence of severe hypertriglyceridemia.

    To evaluate the effect of bariatric surgery on sleep apnea symptoms and obesity-associated morbidity in patients with severe obesity. Prospective study. University hospitals and community centers in Sweden. We investigated the influence of weight loss surgery (n=1729) on sleep apnea symptoms and obesity-related morbidity using a conservatively treated group (n=1748) as a control. Baseline BMI in surgical group (42.2+/-4.4 kg/m(2)) and control group (40.1+/-4.6 kg/m(2)) changed -9.7+/-5 kg/m(2) and 0+/-3 kg/m(2), respectively, at 2-year follow-up. In the surgery group, there was a marked improvement in all obstructive sleep apnea (OSA) symptoms compared with the control group (P sleep apnea symptoms at 2 years. Despite adjustment for weight change and baseline central obesity, subjects reporting loss of OSA symptoms had a lower 2-year incidence of diabetes and hypertriglyceridemia. Improvement in OSA in patients losing weight may provide health benefits in addition to weight loss alone.

    Lipasin (also known as C19ORF80, RIFL, ANGPTL8 and betatrophin) is a newly discovered circulating factor that regulates lipid metabolism and promotes pancreatic β-cell proliferation. Whether circulating levels of lipasin in humans are altered in a) type 2 diabetes; b) obesity and c) the postprandial state, however, is unknown. The current study aimed to compare serum lipasin levels in those who were a) non-diabetic (N=15) or diabetic (BMI- and age-matched; N=14); b) lean or obese (N=53 totally) and c) fasting and 2 hours following a defined meal (N=12). Serum lipasin levels were determined by the enzyme-linked immunosorbent assay. Lipasin levels [mean±SEM] were increased by more than two fold (Plipasin levels were positively correlated with BMI (rho=0.49, Plipasin/betatrophin is nutritionally-regulated hepatokine that is increased in human type 2 diabetes and obesity.

    Salivary gland dysfunction in several systemic diseases has been shown to decrease the quality of life in patients. In non-insulin dependent diabetes mellitus (NIDDM), inadequate salivary gland function has been evidenced to closely associate with this abnormal glycemic control condition. Although several studies demonstrated that NIDDM has a positive correlation with impaired salivary gland function, including decreased salivary flow rate, some studies demonstrated contradictory findings. Moreover, the changes of the salivary gland function in pre-diabetic stage known as insulin resistance are still unclear. The aim of this review is to comprehensively summarize the current evidence from in vitro, in vivo and clinical studies regarding the relationship between NIDDM and salivary gland function, as well as the correlation between obesity and salivary gland function. Consistent findings as well as controversial reports and the mechanistic insights regarding the effect of NIDDM and obesity-insulin resistance on salivary gland function are also presented and discussed.

    2014-08-01

    Full Text Available Obesity and diabetes mellitus are common diseases in humans, dogs and cats and their prevalence is increasing. Obesity has been clearly identified as a risk factor for type 2 diabetes in humans and cats but recent data are missing in dogs, although there is evidence that the unprecedented rise in canine obesity in the last decade has led to a rise in canine diabetes of similar magnitude. The insulin resistance of obesity has often been portrayed as major culprit in the loss of glucose control; however, insulin resistance alone is not a good indicator of progression to diabetes in people or pets. A loss of beta cell function is necessary to provide the link to impaired fasting and post-prandial plasma glucose. Increased endogenous glucose output by the liver is also a prerequisite for the increase in fasting blood glucose when non-diabetic obese humans and pets develop diabetes. This may be due to decreased hepatic insulin sensitivity, decreased insulin concentrations, or a combination of both. While inflammation is a major link between obesity and diabetes in humans, there is little evidence that a similar phenomenon exists in cats. In dogs, more studies are needed to examine this important issue.

    Full Text Available Abstract Background Severe obesity is associated with important morbidity and increased mortality. The successes of lifestyle modifications and drug therapy have been partial and mostly unsustained in reducing obesity and its comorbidities. Bariatric surgery, particularly biliopancreatic diversion with duodenal switch reduces efficiently excess body weight and improves metabolic and cardiovascular functions. Case presentation A 56-year-old man with severe clinical obesity underwent a biliopancreatic diversion with a duodenal switch after unsuccessful treatment with weight loss pharmacotherapy. He had diabetes, hypertension and sleep apnea syndrome and was on three medications for hypertension and two hypoglycemic agents in addition to > 200 insulin units daily. Eleven months after the surgery, he had lost 40% of his body weight. The lipid profile showed great improvement and the hypertension and diabetes were more easily controlled with no more insulin needed. The pseudonormalized pattern of left ventricular diastolic function improved and ventricular walls showed decreased thickness. Conclusion Biliopancreatic diversion may bring metabolic and cardiovascular benefits in severely obese patients from a cardiovascular perspective.

    The International Diabetes Federation Taskforce on Epidemiology and Prevention of Diabetes convened a consensus working group of diabetologists, endocrinologists, surgeons and public health experts to review the appropriate role of surgery and other gastrointestinal interventions in the treatment and prevention of Type 2 diabetes. The specific goals were: to develop practical recommendations for clinicians on patient selection; to identify barriers to surgical access and suggest interventions for health policy changes that ensure equitable access to surgery when indicated; and to identify priorities for research. Bariatric surgery can significantly improve glycaemic control in severely obese patients with Type 2 diabetes. It is an effective, safe and cost-effective therapy for obese Type 2 diabetes. Surgery can be considered an appropriate treatment for people with Type 2 diabetes and obesity not achieving recommended treatment targets with medical therapies, especially in the presence of other major co-morbidities. The procedures must be performed within accepted guidelines and require appropriate multidisciplinary assessment for the procedure, comprehensive patient education and ongoing care, as well as safe and standardized surgical procedures. National guidelines for bariatric surgery need to be developed for people with Type 2 diabetes and a BMI of 35 kg/m2 or more. PMID:21480973

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is the commonest liver condition in the world, accounting for 20-30% of the adult population, and encompasses a spectrum of liver disorders characterized by fat accumulation within the liver, associated or not with varying degrees of hepatic inflammation and liver fibrosis through to cirrhosis. The prevalence of NAFLD increases significantly in the presence of obesity (60-80% and type 2 diabetes (60%. NAFLD is associated with metabolic disorders (type 2 diabetes, obesity and hyperlipidemia grouped together as the metabolic syndrome (MetS. It is now regarded as the hepatic manifestation of this syndrome and is closely linked to insulin resistance (IR.The presence of NAFLD predicts the development of type 2 diabetes independent of established risk factors. NAFLD patients should therefore be screened for diabetes, including by the Oral Glucose Tolerance Test (OGTT if there any abnormalities of fasting blood glucose (FBG and given appropriate lifestyle advice. Early diagnosis with the institution of lifestyle measures could help prevent or retard the onset of these metabolic disorders. Type 2 diabetes causes more severe non-alcoholic steatohepatitis (NASH, and patients with diabetes have an increased risk for cirrhosis and the development of hepatocellular carcinoma (HCC

    Objectives To examine the relationships between prepregnancy diabetes mellitus (DM), gestational diabetes mellitus (GDM), and prepregnancy body mass index, with several adverse birth outcomes: preterm delivery (PTB), low birthweight (LBW), and macrosomia, comparing American Indians and Alaska Natives (AI/AN) with other race/ethnic groups. Methods The sample includes 5,193,386 singleton US first births from 2009-2013. Logistic regression is used to calculate adjusted odds ratios controlling for calendar year, maternal age, education, marital status, Kotelchuck prenatal care index, and child's sex. Results AI/AN have higher rates of diabetes than all other groups, and higher rates of overweight and obesity than whites or Hispanics. Neither overweight nor obesity predict PTB for AI/AN, in contrast to other groups, while diabetes predicts increased odds of PTB for all groups. Being overweight predicts reduced odds of LBW for all groups, but obesity is not predictive of LBW for AI/AN. Diabetes status also does not predict LBW for AI/AN; for other groups, LBW is more likely for women with DM or GDM. Overweight, obesity, DM, and GDM all predict higher odds of macrosomia for all race/ethnic groups. Conclusions for Practice Controlling diabetes in pregnancy, as well as prepregnancy weight gain, may help decrease preterm birth and macrosomia among AI/AN.

    Full Text Available Inflammatory biomarkers provide a minimally invasive means for early detection and specific treatment of metabolic syndrome and related disorders. The objective of this work was to search for inflammatory biomarkers of cardiometabolic risk in obese type 2 diabetics. The study was performed on 165 persons attending the medical outpatient clinic of Ismailia General Hospital. Their mean age was (50.69 ± 10.15 years. They were divided into three groups. The control group was composed of 55 non-obese, non-diabetic healthy volunteers, 32 males and 23 females. Two study groups were included in this study: group 2 was composed of 55 obese, non-diabetic subjects, 25 males and 30 females matched for age and gender. All patients including the control were subjected to clinical history taking, a clinical examination for the measurement of body mass index (BMI. Investigations were carried out for fasting blood glucose, fasting serum insulin, insulin resistance (IR, the lipid profile, lipoprotein band lipoprotein phospholipase A2, and non-high-density lipoprotein cholesterol (non-HDL-C. Urea, albumin and creatinine analysis and liver function tests were performed, and a complete blood count (CBC was taken. Hemoglobin A1C (HbA1C, serum high-sensitivity C-reactive protein (hs-CRP, interleukin-6 (IL-6 and tumor necrosis factor-α (TNF-α were tested. There were statistically significant differences among the studied groups in terms of total cholesterol, non-HDL-C, high-density lipoprotein cholesterol (HDL-C, triglycerides (TG, low-density lipoprotein cholesterol (LDL-C, lipoprotein-associated phospholipase A2 and apolipoprotein B.

    Full Text Available In contrast to the adverse outcomes of obesity in general population, increased body mass index (BMI is associated with improved survival in hemodialysis (CHD patients. The aim of this retrospective study was to evaluate the association between obesity and mortality by diabetic status among 98 maintenance CHD patients. The median follow up was 33 (19, 56 months. Mean age was 49±13 years, 66% were male and 48 % had obesity. 45% of obese subjects were diabetic. Among the subgroups of study population, survival of diabetic obese patients was significantly lower compared to non-diabetic obese subjects (p=0.007 (Figure 1. The subgroup comparisons showed that diabetic obese patients tend to have higher truncal fat percentage (p<0.001 and lower lean body mass standardized by body surface area compared to nondiabetic counterparts although difference was not statistically significance. Diabetic obese patients had higher leptin (p=0.001 and high sensitivity C-reactive protein levels (0.005. Additionally, protein thiols (P-SH were significantly decreased in diabetic obese participants (p=0.03. Although, elevated body fatness appears to be protective for CHD population, presence of overt diabetes alters this advantage by increasing inflammation and oxidative stress.fx1

    Intrahepatic expression of dipeptidyl peptidase-4 (DPP4), and circulating DPP4 (cDPP4) levels and its enzymatic activity, are increased in non-alcoholic fatty liver disease (NAFLD) and in type 2 diabetes mellitus and/or obesity. DPP4 has been implicated as a causative factor in NAFLD progression but few studies have examined associations between cDPP4 activity and NAFLD severity in humans. This study aimed to examine the relationship of cDPP4 activity with measures of liver disease severity in NAFLD in subjects with diabetes and/or obesity. cDPP4 was measured in 106 individuals with type 2 diabetes who had transient elastography (Cohort 1) and 145 individuals with morbid obesity who had liver biopsy (Cohort 2). Both cohorts had caspase-cleaved keratin-18 (ccK18) measured as a marker of apoptosis. Natural log increases in cDPP4 activity were associated with increasing quartiles of ccK18 (Cohorts 1 and 2) and with median liver stiffness ≥10.3 kPa (Cohort 1) and significant fibrosis (F ≥ 2) on liver biopsy (Cohort 2). In diabetes and/or obesity, cDPP4 activity is associated with current apoptosis and liver fibrosis. Given the pathogenic mechanisms by which DPP4 may progress NAFLD, measurement of cDPP4 activity may have utility to predict disease progression and DPP4 inhibition may improve liver histology over time. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    Although metabolic syndrome is associated with increased sympathetic activity that chronically stimulates β-adrenoceptors, the β-adrenoceptor signaling pathway has been poorly studied in this situation. We studied the β-adrenoceptor signaling pathway in Zucker lean, obese, and obese diabetic rats. Experimental, prospective study. University medical research laboratory. Adult male Zucker lean (control), obese, and obese diabetic rats. The effects of β-adrenoceptor stimulation were investigated in vitro in isolated left ventricular papillary muscles in control, obese, and obese diabetic rats. β1-, β2-, and β3-adrenoceptors and multidrug resistance-associated protein 4 were quantified by Western Blotting. Triglyceride, cholesterol, leptin, adiponectin, and C-peptide plasma concentrations were measured. Data are mean ± SD. Hyperlipidemia, high leptin, and C-peptide concentrations were observed in obese and obese diabetic strains, whereas hyperglycemia occurred only in the diabetic strain. The positive inotropic effect of isoproterenol was slightly reduced in obese rats (183% ± 11% of baseline; p = 0.003; n = 7) and markedly reduced in obese diabetic rats (137% ± 18% of baseline; p < 0.001; n = 10) when compared with control rats (210% ± 17% of baseline; n = 9). β1-adrenoceptors were down-regulated in obese (-41%; p = 0.02) and diabetic (-54%; p = 0.003) when compared with control rats, whereas β3-adrenoceptors and multidrug resistance-associated protein expression remained unchanged. Direct stimulation of adenylate cyclase with forskolin or administration of 3',5'-cyclic adenosine monophosphate suggests that subtle impairments also occurred beside the down-regulation of β1-adrenoceptor. The positive inotropic effect of β-adrenoceptor stimulation is slightly decreased in Zucker obese rats and was more markedly decreased in Zucker diabetic rats. These decreases are mainly related to β1-adrenoceptor down-regulation.

    Full Text Available The digestive tract of mammals and other animals is colonized by trillions of metabolically-active microorganisms. Changes in the gut microbiota have been associated with obesity in both humans and laboratory animals. Dietary modifications can often modulate the obese gut microbial ecosystem towards a more healthy state. This phenomenon should preferably be studied using dietary ingredients that are relevant to human nutrition. This study was designed to evaluate the influence of whole-wheat, a food ingredient with several beneficial properties, on gut microorganisms of obese diabetic mice. Diabetic (db/db mice were fed standard (obese-control or whole-wheat isocaloric diets (WW group for eight weeks; non-obese mice were used as control (lean-control. High-throughput sequencing using the MiSeq platform coupled with freely-available computational tools and quantitative real-time PCR were used to analyze fecal bacterial 16S rRNA gene sequences. Short-chain fatty acids were measured in caecal contents using quantitative high-performance liquid chromatography photo-diode array analysis. Results showed no statistical difference in final body weights between the obese-control and the WW group. The bacterial richness (number of Operational Taxonomic Units did not differ among the treatment groups. The abundance of Ruminococcaceae, a family containing several butyrate-producing bacteria, was found to be higher in obese (median: 6.9% and WW-supplemented mice (5.6% compared to lean (2.7%, p = 0.02, Kruskal-Wallis test. Caecal concentrations of butyrate were higher in obese (average: 2.91 mmol/mg of feces but especially in WW-supplemented mice (4.27 mmol/mg compared to lean controls (0.97 mmol/mg, while caecal succinic acid was lower in the WW group compared to obese but especially to the lean group. WW consumption was associated with ∼3 times higher abundances of Lactobacillus spp. compared to both obese and lean control mice. Analysis of weighted Uni

    We examined the clinical characteristics of non-obese Japanese children with type 2 diabetes mellitus (T2DM) not associated with β-cell autoimmunity. Of 218 children who were diagnosed as having T2DM by a school urine glucose screening program in Tokyo, 24 were identified as being non-obese and were enrolled in this study. None of the children had any evidence of β-cell autoimmunity or genetic disorders. The mean ages at diagnosis and at the study were 12.5 ± 1.7 and 22.4 ± 5.7 years, respectively. Females were predominant (M/F ratio: 4/20). Family history of T2DM, mostly of the non-obese type, was present in 62.5% of the cases. In regard to the birth weight, 20.8% had a history of low birth weight, and 8.3% were large for gestational age. The mean fasting insulin level, HOMA-R, HOMA-β, and an insulinogenic index on the OGTT at the time of diagnosis were 11.8 ± 7.8 μU/ml, 5.4 ± 3.8, 96.1 ± 55.0 and 0.16 ± 0.14, respectively. Most patients were treated by either oral hypoglycemic drug (45.8%) or insulin (50.0%) therapy at the study, with the mean interval to the start of pharmacological treatment of 3.1 ± 2.3 years. Non-obese children with T2DM seemed to show lower insulin secretory capacities with mild, but evident, insulin resistance even from the time of diagnosis, and also earlier requirement of pharmacological therapies during the clinical course. Some genetic factors not associated with autoimmunity may play a role in the etiology of T2DM in non-obese children. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    The prevalence of obesity in Thai children is increasing. These individuals are at increased risks of metabolic syndrome that includes insulin resistance, type 2 diabetes mellitus (T2DM), polycystic ovary syndrome (PCOS), dyslipidemia and hypertension. PCOS has been known to be associated with insulin resistance. To compare the insulin sensitivity between obese adolescent girls with PCOS and those without PCOS. We reviewed demographic and hormonal data of 6 obese adolescent girls with PCOS and compared with 6 age, weight and BMI-matched non-PCOS controls. Each subject underwent an oral glucose tolerance test. Homeostasis model assessment of insulin resistance score (HOMA-IR score) in obese adolescent girls with PCOS was significantly higher than in girls without PCOS with median and range as follows (16.5 [3.8, 21.8] vs. 4.1 [3.3, 6.9], p = 0.04). Our study demonstrates that obese adolescent girls with PCOS have more severe insulin resistance measured by HOMA-IR score than girls without PCOS independent of the degree of obesity. Since insulin resistance is a metabolic precursor of future cardiovascular diseases, obese adolescent girls with PCOS might be at greater risk of developing cardiovascular disease in later adulthood than their non-PCOS counterparts.

  14. Do diabetes and obesity affect the metabolic response to exercise?

    Exercise is recommended as therapeutic intervention for people at risk to develop type 2 diabetes to prevent or treat the disease. Recent studies on the influence of obesity and type 2 diabetes on the outcome of exercise programs are discussed. Poor glycemic control before an intervention can be a risk factor of reduced therapeutic benefit from exercise. But the acute metabolic response to exercise and the transcriptional profile of the working muscle is similar in healthy controls and type 2 diabetic patients, including but not limited to intact activation of skeletal muscle AMP-activated kinase signaling, glucose uptake and expression of peroxisome proliferator-activated receptor gamma coactivator 1α. The increase in plasma acylcarnitines during exercise is not influenced by type 2 diabetes or obesity. The hepatic response to exercise is dependent on the glucagon/insulin ratio and the exercise-induced increase in hepatokines such as fibroblast growth factor 21 and follistatin is impaired in type 2 diabetes and obesity, but consequences for the benefit from exercise are unknown yet. Severe metabolic dysregulation can reduce the benefit from exercise, but the intact response of key metabolic regulators in exercising skeletal muscle of diabetic patients demonstrates the effectiveness of exercise programs to treat the disease.

    Full Text Available Andrographis paniculata is an annual herb and widely cultivated in Southeast Asian countries for its medicinal use. In recent investigations, A. paniculata was found to be effective against Type 1 diabetes mellitus (Type 1 DM. Here, we used a non-genetic out-bred Sprague-Dawley rat model to test the antidiabetic activity of A. paniculata against Type 2 diabetes mellitus (Type 2 DM. Proton Nuclear Magnetic Resonance (1H-NMR spectroscopy in combination with multivariate data analyses was used to evaluate the A. paniculata and metformin induced metabolic effects on the obese and obese–diabetic (obdb rat models. Compared to the normal rats, high levels of creatinine, lactate, and allantoin were found in the urine of obese rats, whereas, obese-diabetic rats were marked by high glucose, choline and taurine levels, and low lactate, formate, creatinine, citrate, 2-oxoglutarate, succinate, dimethylamine, acetoacetate, acetate, allantoin and hippurate levels. Treatment of A. paniculata leaf water extract was found to be quite effective in restoring the disturbed metabolic profile of obdb rats back towards normal conditions. Thisstudy shows the anti-diabetic potential of A. paniculata plant extract and strengthens the idea of using this plant against the diabetes. Further classical genetic methods and state of the art molecular techniques could provide insights into the molecular mechanisms involved in the pathogenesis of diabetes mellitus and anti-diabetic effects of A. paniculata water extract.

    It is unclear whether the frequent non-severe episodes of hypoglycaemia observed during intensive glucose control in individuals with type 1 diabetes (T1D) are associated with subsequent weight gain. We analysed the association between non-severe hypoglycaemia and weight gain in 1441 Diabetes Control and Complication Trial (DCCT) participants. Non-severe hypoglycaemia was assessed by hypo-score (ie, number of blood glucose values gain. The annual weight gain by hypo-score tertiles was 0.8 ± 1.2 (T1), 1.3 ± 1.5 (T2) and 1.4 ± 1.3 kg/y (T3), P gain of 1.8 kg/y was 2.14 (95% CI, 1.56-2.93) for T2, and 2.53 (95%CI, 1.85-3.45) for T3 vs T1. These differences in weight gain and in risk of weight gain remained significant after adjustment for sex, age, duration of diabetes, HbA1c at baseline and treatment arms. In conclusion, our analysis shows a significant association between non-severe hypoglycaemia and weight gain in individuals with T1D from the DCCT. © 2017 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Acylation Stimulating Protein (ASP has been shown to influence adipose tissue triglyceride (TG storage. The aim was to examine ethnic differences in ASP and leptin levels in relation to lipid profiles and postprandial changes amongst African American (AA and Caucasian American (CA women matched for BMI. Methods 129 women were recruited in total (age 21 – 73 y: 24 non-obese (BMI 2 CA, 27 obese (BMI ≥ 30 kg/m2 CA, 13 obese diabetic CA, 25 non-obese AA, 25 obese AA, and 15 obese diabetic AA. Cholesterol, HDL-C, LDL-C, apoB, glucose and insulin were measured at baseline. TG, non-esterified fatty acids, leptin, and ASP were measured at baseline and postprandially following a fat meal. Results ASP, leptin, insulin and TG were significantly increased in obese subjects within each race. However, AA women had significantly lower ASP and TG than CA women at all BMI. Obese and diabetic AA women had significantly lower apoB levels than CA women when compared to their respective counterparts. For AA women, fasting ASP was positively correlated with BMI, cholesterol, apoB, LDL-C and glucose. For CA women, fasting ASP was positively correlated with BMI, leptin, glucose and insulin. However, for any given BMI, ASP was significantly reduced in AA vs CA (p = 0.0004. Similarly, for any given leptin level or TG levels, ASP was significantly lower in AA women (p = 0.041 and p = 0.003, respectively. Conclusion CA women have higher baseline TG levels and an earlier TG peak that is accompanied with higher ASP levels suggesting increased ASP resistance, while AA women have lower baseline TG levels and a later TG peak at lower ASP levels suggesting increased ASP sensitivity. This may explain why AA women may have fewer metabolic complications, such as diabetes and CVD, when compared to their Caucasian counterparts at the same level of obesity.

    BACKGROUND: Skeletal muscle is one of the primary tissues involved in the development of type 2 diabetes (T2D). The close association between obesity and T2D makes it difficult to isolate specific effects attributed to the disease alone. Therefore, here we set out to identify and characterize...... in sphingolipid metabolism was transcriptionally regulated. CONCLUSIONS: Our findings identify inherent characteristics in myocytes, as a memory of the in vivo phenotype, without the influence from a diabetic or obese extracellular environment, highlighting their importance in the development of T2D....... intrinsic properties of myocytes, associated independently with T2D or obesity. METHODS: We generated and analyzed RNA-seq data from primary differentiated myotubes from 24 human subjects, using a factorial design (healthy/T2D and non-obese/obese), to determine the influence of each specific factor...

  19. Serotonin as a New Therapeutic Target for Diabetes Mellitus and Obesity

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Serotonin (5-hydroxytryptamine [5-HT] is a monoamine that has various functions in both neuronal and non-neuronal systems. In the central nervous system, 5-HT regulates mood and feeding behaviors as a neurotransmitter. Thus, there have been many trials aimed at increasing the activity of 5-HT in the central nervous system, and some of the developed methods are already used in the clinical setting as anti-obesity drugs. Unfortunately, some drugs were withdrawn due to the development of unwanted peripheral side effects, such as valvular heart disease and pulmonary hypertension. Recent studies revealed that peripheral 5-HT plays an important role in metabolic regulation in peripheral tissues, where it suppresses adaptive thermogenesis in brown adipose tissue. Inhibition of 5-HT synthesis reduced the weight gain and improved the metabolic dysfunction in a diet-induced obesity mouse model. Genome-wide association studies also revealed genetic associations between the serotonergic system and obesity. Several genetic polymorphisms in tryptophan hydroxylase and 5-HT receptors were shown to have strong associations with obesity. These results support the clinical significance of the peripheral serotonergic system as a therapeutic target for obesity and diabetes.

    Severely obese parturients have increased 'cannot intubate, cannot oxygenate' risk during Caesarean section under general anaesthesia. Front-of-neck access (FONA) at the cricothyroid membrane (CTM) is definitive management; however, attempted FONA can fail. Point-of-care ultrasonography may provide useful information about CTM depth to aid FONA in obesity. This study determined the difference in CTM depth between severely obese and non-obese parturients, utilising ultrasonography. In this prospective observational study, two anaesthetists performed airway ultrasonography on 15 severely obese (BMI >45 kg m -2 ) and 15 normal-weight (BMI ≤25 kg m -2 ) parturients in the third trimester, using the transverse and longitudinal planes, sniffing and extended head positions, and nil and firm transducer pressures. The primary outcome was CTM depth (millimetres) measured in the transverse plane with the head extended and nil transducer pressure. Secondary outcomes included CTM depth measurements using other factor configurations. Intra-class correlation coefficients assessed the inter-observer reliability. CTM depth measured in the transverse plane with head extended and nil transducer pressure was significantly greater in severely obese parturients, mean 18.0 mm (95% confidence interval 16.3-19.8), vs 10.6 mm (8.81-12.4) in non-obese (P<0.001); mean difference 7.4 mm (4.9-9.9; P<0.001). CTM depths were increased in the severely obese group regardless of scanning plane, head and neck position, or transducer pressure (all P<0.001). There was excellent inter-observer reliability. Cricothyroid membrane depth is significantly increased in severely obese vs normal-weight parturients independently of scanning plane, head and neck position, or transducer pressure.

    The incidence of type 1 diabetes in children is increasing in Sweden, as is the prevalence of maternal overweight/obesity. Therefore, the aim of this study was to investigate if maternal overweight/obesity increases the risk of type 1 diabetes in offspring of parents with and without diabetes, and of different ethnicities. The study cohort comprised 1,263,358 children, born in Sweden between 1992 and 2004. Children were followed from birth until diagnosis of type 1 diabetes, emigration, death or end of follow-up in 2009, whichever occurred first. First trimester maternal BMI was calculated (kg/m(2)). Poisson regression was used to calculate incidence rate ratios (IRRs) with 95% CI for type 1 diabetes in the offspring. The risk of type 1 diabetes was increased in offspring of parents with any type of diabetes regardless of parental ethnicity. High first trimester maternal BMI was associated with increased risk of type 1 diabetes only in offspring of parents without diabetes (IRR 1.33 [95% CI 1.20, 1.48]). Increasing incidence of type 1 diabetes in children with non-diabetic parents may partly be explained by increasing prevalence of maternal overweight/obesity.

    The purpose of this study is to determine an appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis among Korean adults.This study involved a cross-sectional analysis using data from the Korean National Health and Nutrition Examination Survey from 2012 to 2014. Incidence rates of periodontitis with the 95% confidence interval (CI) were evaluated. The predictive accuracy of age for periodontitis was determined by calculating the area under curve (AUC) on the basis of the receiver operating characteristic (ROC) curve.The cutoff value of age was 43 years in men having periodontitis with an AUC of 0.70 with 95% CI of 0.69 to 0.72. The AUC was 0.72 (95% CI: 0.70-0.73), and the cutoff value of age (49 years) was identified for the moderate periodontitis in women. The cutoff values for age with AUCs and 95% CI for individuals with periodontitis were 46 years (0.72 [0.71-0.73]), 43 years (0.73 [0.72, 0.74]), 45 years (0.71 [0.70,0.72]), 43 years (0.73 [0.72, 0.74]), and 45 years (0.74 [0.72, 0.75]) for no obesity, no abdominal obesity, no diabetes mellitus, no hypertension, and no metabolic syndrome groups, respectively.This study proposed the guideline for the appropriate age threshold at which to recommend the evaluation of moderate and severe periodontitis for the general population and additionally added the guideline for the individuals without systemic disease including diabetes mellitus, hypertension, metabolic syndrome, and obesity. This study suggests that the participants with certain age may be recommended for the regular periodontal evaluation.

    Full Text Available BACKGROUND: Central obesity is the accumulation of visceral (intra-abdominal fat and is strongly known to be associated with insulin resistance and type 2 diabetes mellitus (T2DM. Obesity can cause adipocyte hypertrophy that results in dysregulation of adipokine expression. The abnormal function of adipocytes may play an important role in the development of a chronic low-grade proinflammatory state associated with obesity. Adiponectin, retinol binding protein (RBP-4 and fetuin-A play a role in the pathophysiology of insulin resistance. Expression of fetuin-A is increased due to fat accumulation in the liver. Elevated concentration of fetuin-A in the circulation can impair insulin signaling in muscle and liver as well as suppress adiponectin secretion, although its molecular mechanism is still unclear. The aim of this study was to identify the relationship of fetuin-A, adiponectin, RBP-4 and hsCRP with insulin resistance in obese non diabetic men. METHODS: This was an observational study with a cross-sectional design. The study subjects were 64 men with non diabetic abdominal obesity, characterized by waist circumference of 98.47±5.88 cm and fasting blood glucose of 85.75±8.36 mg/dL. RESULTS: This study showed that fetuin-A was positively correlated with HOMA-IR in obese non diabetic men with insulin resistance (r=0.128; p=0.570, although not significant. Fetuin-A was found to be correlated with adiponectin, RBP-4 and hsCRP (r=0.150; p=0.233; r=0.050; p=0.711; r=-0.04; p=0.445, although not significant. CONCLUSIONS: The concentration of fetuin-A showed a tendency to be positively correlated with HOMA-IR and with RBP-4 in obese non diabetic men, although statistically not significant. The concentration of fetuin-A showed a tendency to be negatively correlated with adiponectin and hsCRP although statistically not significant. There was no interrelationship between fetuin-A, adiponectin, RBP-4, hsCRP and HOMA-IR. Elevated concentrations of fetuin

    Full Text Available Obesity is a worldwide epidemic, and severe obesity is a risk factor for many diseases, including diabetes, heart disease, stroke, and some cancers. Endocannabinoid system (ECS signaling in the brain and peripheral tissues is activated in obesity and plays a role in the regulation of body weight. The main research question here was whether quantitative measurement of plasma endocannabinoids, anandamide, and related N-acylethanolamines (NAEs, combined with genotyping for mutations in fatty acid amide hydrolase (FAAH would identify circulating biomarkers of ECS activation in severe obesity.Plasma samples were obtained from 96 severely obese subjects with body mass index (BMI of > or = 40 kg/m(2, and 48 normal weight subjects with BMI of A (P129T mutation by comparing plasma ECS metabolite levels in the FAAH 385 minor A allele carriers versus wild-type C/C carriers in both groups. The main finding was significantly elevated mean plasma levels of anandamide (15.1+/-1.4 pmol/ml and related NAEs in study subjects that carried the FAAH 385 A mutant alleles versus normal subjects (13.3+/-1.0 pmol/ml with wild-type FAAH genotype (p = 0.04, and significance was maintained after controlling for BMI.Significantly increased levels of the endocannabinoid anandamide and related NAEs were found in carriers of the FAAH 385 A mutant alleles compared with wild-type FAAH controls. This evidence supports endocannabinoid system activation due to the effect of FAAH 385 mutant A genotype on plasma AEA and related NAE analogs. This is the first study to document that FAAH 385 A mutant alleles have a direct effect on elevated plasma levels of anandamide and related NAEs in humans. These biomarkers may indicate risk for severe obesity and may suggest novel ECS obesity treatment strategies.

    Full Text Available ObjectivesThe objectives were to evaluate (1 the metabolic profile and cardiometabolic risk in overweight/obese children at first assessment, stratifying patients according to severity of overweight and age; and (2 to investigate the relationship between family history (FH for obesity and cardiometabolic diseases and severity of childhood obesity.MethodsIn this cross-sectional, retrospective, observational study, 260 children (139 female, aged between 2.4 and 17.2 years, with overweight and obesity were recruited. Data regarding FH for obesity and cardiometabolic diseases were collected. Each patient underwent clinical and auxological examination and fasting blood sampling for metabolic profile. Homeostasis model assessment of insulin resistance (HOMA-IR, triglyceride-to-high-density lipoprotein cholesterol ratio, and atherogenic index of plasma were calculated. To evaluate the severity of obesity, children were divided into two groups for BMI standard deviation (SD ≤2.5 and BMI SD >2.5. Moreover, study population was analyzed, dividing it into three groups based on the chronological age of patient (<8, 8–11, >11 years.ResultsBMI SD was negatively correlated with chronological age (p < 0.005 and significantly higher in the group of children <8 years. BMI SD was positively associated with FH for obesity. Patients with more severe obesity (BMI SD >2.5 were younger (p < 0.005, mostly prepubertal, presented a significantly higher HOMA-IR (p = 0.04, and had a significantly higher prevalence of FH for arterial hypertension, type 2 diabetes mellitus, and coronary heart disease than the other group.Conclusion(1 Family history of obesity and cardiometabolic diseases are important risk factors for precocious obesity onset in childhood and are related to the severity of obesity.

    Fructans contribute significantly to dietary fiber with beneficial effects on gastrointestinal physiology in healthy individuals and offer a promising approach to treating some diseases. Two experiments (Experiment 1 = rats with normal weight; Experiment 2 = obese rats) were developed to compare the effects of three fructan sources (Cichorium intybus L. Asteraceae, Helianthus tuberosus L. Asteraceae and Agave angustifolia ssp. tequilana Haw, Agavaceae) on body weight change, blood metabolites and fecal bacteria in non-diabetic (ND) and diabetic (D) rats. In Experiment 1 total body weight gain and daily feed intake in D and ND rats decreased (P tequilana decreased blood cholesterol and LDL and liver steatosis. For both ND and D rats, fecal Lactobacillus spp. and Bifidobacterium spp. counts were higher (P < 0.05) with fructan supplements.

    Full Text Available During the last three to four decades the prevalence of obesity and diabetes mellitus has greatly increased worldwide, including in the United States. Both the short- and long-term forecasts predict serious consequences for the near future, and encourage the development of solutions for the prevention and management of obesity and diabetes mellitus. Transient receptor potential (TRP channels were identified in tissues and organs important for the control of whole body metabolism. A variety of TRP channels has been shown to play a role in the regulation of hormone release, energy expenditure, pancreatic function, and neurotransmitter release in control, obese and/or diabetic conditions. Moreover, dietary supplementation of natural ligands of TRP channels has been shown to have potential beneficial effects in obese and diabetic conditions. These findings raised the interest and likelihood for potential drug development. In this mini-review, we discuss possibilities for better management of obesity and diabetes mellitus based on TRP-dependent mechanisms.

    Full Text Available Abstract Background Body fat mass distribution and deposition are determined by multiple environmental and genetic factors. Obesity is associated with insulin resistance, hyperinsulinemia, and type 2 diabetes. We previously identified evidence for genotype-by-diabetes interaction on obesity traits in Strong Heart Family Study (SHFS participants. To localize these genetic effects, we conducted genome-wide linkage scans of obesity traits in individuals with and without type 2 diabetes, and in the combined sample while modeling interaction with diabetes using maximum likelihood methods (SOLAR 2.1.4. Methods SHFS recruited American Indians from Arizona, North and South Dakota, and Oklahoma. Anthropometric measures and diabetes status were obtained during a clinic visit. Marker allele frequencies were derived using maximum likelihood methods estimated from all individuals and multipoint identity by descent sharing was estimated using Loki. We used variance component linkage analysis to localize quantitative trait loci (QTLs influencing obesity traits. We tested for evidence of additive and QTL-specific genotype-by-diabetes interactions using the regions identified in the diabetes-stratified analyses. Results Among 245 diabetic and 704 non-diabetic American Indian individuals, we detected significant additive gene-by-diabetes interaction for weight and BMI (P P Conclusion These results suggest distinct genetic effects on body mass in individuals with diabetes compared to those without diabetes, and a possible role for one or more genes on chromosome 1 in the pathogenesis of obesity.

    2017-11-02

    The rising prevalence of obesity and diabetes cannot be fully explained by known risk factors, such as unhealthy diet, a sedentary lifestyle, and family history. This review summarizes the available studies linking persistent organic pollutants (POPs) to obesity and diabetes and discusses plausible underlying mechanisms. Increasing evidence suggest that POPs may act as obesogens and diabetogens to promote the development of obesity and diabetes and induce metabolic dysfunction. POPs are synthesized chemicals and are used widely in our daily life. These chemicals are resistant to degradation in chemical or biological processes, which enable them to exist in the environment persistently and to be bio-accumulated in animal and human tissue through the food chain. Increasingly, epidemiologic studies suggest a positive association between POPs and risk of developing diabetes. Understanding the relationship of POPs with obesity and diabetes may shed light on preventive strategies for obesity and diabetes.

  14. Exercise improves cardiac autonomic function in obesity and diabetes.

    Physical activity is a key element in the prevention and management of obesity and diabetes. Regular physical activity efficiently supports diet-induced weight loss, improves glycemic control, and can prevent or delay type 2 diabetes diagnosis. Furthermore, physical activity positively affects lipid profile, blood pressure, reduces the rate of cardiovascular events and associated mortality, and restores the quality of life in type 2 diabetes. However, recent studies have documented that a high percentage of the cardiovascular benefits of exercise cannot be attributed solely to enhanced cardiovascular risk factor modulation. Obesity in concert with diabetes is characterized by sympathetic overactivity and the progressive loss of cardiac parasympathetic influx. These are manifested via different pathogenetic mechanisms, including hyperinsulinemia, visceral obesity, subclinical inflammation and increased thrombosis. Cardiac autonomic neuropathy is an underestimated risk factor for the increased cardiovascular morbidity and mortality associated with obesity and diabetes. The same is true for the role of physical exercise in the restoration of the heart cardioprotective autonomic modulation in these individuals. This review addresses the interplay of cardiac autonomic function in obesity and diabetes, and focuses on the importance of exercise in improving cardiac autonomic dysfunction.

    The number of patients with morbid obesity is increasing worldwide. However, the prevalence of morbid obesity is still low in Japan, and therefore few systematic investigations of liver dysfunction in this population have so far been carried out. This study aimed to investigate the clinical characteristics in severe obese Japanese patients undergoing laparoscopic Roux-en-Y gastric bypass surgery (LRYGB). Eighty-four patients with severe obesity, including 61 Japanese and 23 non-Japanese patients, were analyzed. The mean body mass index (BMI) was 43.7±7.8 kg/m 2 , and there was no difference between Japanese and non-Japanese patients. Nonalcoholic fatty liver disease (NAFLD) was observed in 45/59 (76.2%) of the Japanese patients. Although there were no differences in the BMI and body weight, serum alanine aminotransferase (ALT) was higher in Japanese patients in comparison to non-Japanese patients (P<0.05). The indices for insulin resistance were significantly higher in the Japanese patients in comparison to non-Japanese patients (P<0.01). The liver/spleen computed tomography (CT) ratios were lower in Japanese patients (P<0.05). The laboratory data and BMI significantly improved at 1 year after LRYGB in both groups. Racial difference may exist difference may exist in NAFLD in patients with severe obesity. When the BMI is similar, liver dysfunction among Japanese patients with severe obesity tends to be higher than in non-Japanese patients. Japanese patients with severe obesity must therefore reduce their body weight to a greater degree in comparison to non-Japanese patients with the same BMI. LRYGB can achieve effective weight control and lower ALT levels in Japanese patients with severe obesity. (author)

    Full Text Available Introduction. One of the characteristic signs of uremic syndrome is anemia. One of major factors that affects on severity of anemia in ESRD is underlying diseas. The porpuse of this study is to compaire anemia between diabetic and non diabetic ESRD patients. Methods. In a case control study we compared the mean valuse of Hb, Het, MCV, MCH, MCHC, BUN, Cr and duration of dialysis between diabetic and nondiabetic patients on chronic hemodialyis. some variables (such as age, sex, use of erythropoietin, nonderolone decaonats, folic acid, ferrous sulfate, transfusion and blood loss in recent three months and acquired kidney cysts were matched between cases and controls. Results. Means of Hb were 9±1.3 and 8 ± 1.7 in diabetic and non diabetic patients (P<0.05. Mean corposcular volume in diabetic patients (91±3.1 fl was more higher than non diabetic ones (87.1 ± 8.9 (P < 0.05. Other indices had no differences between two groups (P > 0.05. Discussion. Severity of anemia in patients with diabetic nephropathy is milder that other patients with ESRD. So, Anemia as an indicator of chronocity of renal disease in diabetics is missleading.

    The role of brain-derived neurotrophic factor (BDNF) variants on diabetes prevalence, basal adipokine levels, body weight, and cardiovascular risk factors remains unclear in obese patients. This study is aimed at analyzing the effects of rs10767664 BDNF gene polymorphism on diabetes mellitus prevalence, body weight, cardiovascular risk factors, and serum adipokine levels in obese female patients. A total of 507 obese women were enrolled in a prospective way. Biochemical evaluation and anthropometric measures were recorded. The frequency of diabetes mellitus in the group of patients with non-T allele was 20.1 and 28.3% in T-allele carriers. Logistic regression showed a risk of diabetes mellitus of 1.33 (95% CI 1.17-2.08) in subjects with T allele adjusted by age and body mass index (BMI). T-allele carriers with diabetes mellitus have a higher weight, BMI, waist circumference, blood pressure, glucose, homeostasis model assessment insulin resistance (HOMA-IR), insulin, and C-reactive protein (CRP) levels than non-T-allele carriers. rs10767664 polymorphism of BDNF gene is associated with prevalence of diabetes mellitus in obese female patients.

    Several studies have reported that insulin resistance was a major risk factor for the onset of type 2 diabetes mellitus in individuals without diabetes or obesity. We aimed to clarify the association between insulin resistance and glycemic control in Japanese subjects without diabetes or obesity. We conducted a community-based cross-sectional study including 1083 healthy subjects (323 men and 760 women) in an urban area. We performed multivariate regression analyses to estimate the association between the homeostasis model assessment of insulin resistance (HOMA-IR) values and markers of glycemic control, including glycated haemoglobin (HbA1c), 1,5-anhydroglucitol (1,5-AG), and fasting plasma glucose (FPG) levels, after adjustment for potential confounders. Compared with the lowest tertile of HOMA-IR values, the highest tertile was significantly associated with HbA1c and FPG levels after adjustment for potential confounders, both in men (HbA1c: β = 1.83, P = 0.001; FPG: β = 0.49, P HOMA-IR values was inversely associated with 1,5-AG levels compared with the lowest tertile (β = -18.42, P = 0.009) only in men. HOMA-IR values were associated with markers of glycemic control in Japanese subjects without diabetes or obesity. Insulin resistance may influence glycemic control even in a lean, non-diabetic Asian population.

    2015-12-01

    Full Text Available Galectin-3 is an important regulator of inflammation and acts as a receptor for advanced-glycation (AGE and lipoxidation end-products (ALE. Evidence indicates a significant upregulation in circulating levels and visceral adipose tissue production of Galectin-3 in obesity and type 2 diabetes. Recent studies demonstrate development of obesity and dysregulation of glucose metabolism in Galectin-3 “knockout” (KO mice, which also develop accelerated and more severe pathology in models of atherosclerosis and metabolically-induced kidney damage. Thus, evidence that Galectin-3 is an important player in metabolic disease is accumulating. This review discusses current evidence on the connection between Galectin-3 and metabolic disease, focusing on mechanisms by which this galectin modulates adiposity, glucose metabolism and obesity-associated inflammatory responses.

    Non-alcoholic fatty liver disease (NAFLD) is frequent among obese individuals with metabolic syndrome. Variants PNPLA3 p.I148M, TM6SF2 p.E167K and MBOAT7 rs641738 are associated with higher liver fat contents. Here we analyzed 63 biopsied non-obese, non-diabetic patients with NAFLD (39 men, age: 20-72 years) recruited within the German NAFLD CSG program. The frequencies of the PNPLA3, TM6SF2 and MBOAT7 polymorphisms were compared with the remaining patients in the NAFLD CSG cohort and with a control population (n = 174). Serum CK18-M30 was measured by ELISA. In non-obese NAFLD patients, the frequency of the PNPLA3 p.I148M allele (74.6%), but not of the TM6SF2 or MBOAT7 polymorphisms, was significantly (P < 0.05) higher as compared to the other patients in the NAFLD CSG cohort (54.9%) or controls (40.2%). The presence of the minor PNPLA3 p.I148M risk allele increased the risk of developing NAFLD (OR = 3.29, P < 0.001) and was associated with higher steatosis, fibrosis, and serum CK18-M30 levels (all P < 0.05). According to the population attributable fraction (PAF), 49.8% of NAFLD cases could be eliminated if the PNPLA3 mutation was absent. The MBOAT7 polymorphism was more frequent (P = 0.019) in patients with severe hepatic steatosis. In conclusion, PNPLA3, and to a lesser extent, MBOAT7 variants are associated with NAFLD risk and modulate liver injury in non-obese patients without diabetes.

    Exercise training has potential benefits for patients with hyperlipidemia and/or non-insulin dependent diabetes mellitus. In nondiabetic, nonobese subjects with hypertriglyceridemia, exercise training alone increased insulin sensitivity, improved glucose tolerance, and lowered serum triglyceride and cholesterol levels. These improvements did not occur when exercise training alone was given to similar patients with impaired glucose tolerance. In severely obese (X = 125 kg) subjects without diabetes melitus, a 600 calorie diet alone decreased glucose and insulin concentrations and improved glucose tolerance but did not increase insulin sensitivity. The addition of exercise training improved insulin sensitivity. Obese, non-insulin dependent diabetes mellitus subjects on sulfonylurea therapy alone increased insulin levels but failed to improve insulin sensitivity or glucose levels. In contrast, the addition of exercise training to this medication resulted in improved insulin sensitivity and lowered glucose levels. We conclude that exercise training has major effects on lowering triglyceride levels in hyperlipidemic subjects and can potentiate the effect of diet or drug therapy on glucose metabolism in patients with non-insulin dependent diabetes mellitus.

    Obesity is currently an exceptionally common problem in humans. The last several years have produced a significant number of breakthroughs in obesity related areas of investigation. Triglycerides are considered the main form of storage of excess calories in fat. A key enzyme in the synthesis of triglycerides is acylCoA: diacylglycerol acyltransferase (DGAT). Recent studies have shown that mice deficient in this enzyme are resistant to diet induced obesity and have increased insulin and leptin sensitivity. These effects suggest that inhibition of DGAT in vivo may be a novel therapeutic target not only for obesity but also for diabetes.

    The ob/ob mouse is genetically deficient in leptin and exhibits a phenotype that includes obesity and non-insulin-dependent diabetes melitus. This phenotype closely resembles the morbid obesity seen in humans. In this study, we demonstrate that a single intramuscular injection of a recombinant adeno-associated virus (AAV) vector encoding mouse leptin (rAAV-leptin) in ob/ob mice leads to prevention of obesity and diabetes. The treated animals show normalization of metabolic abnormalities including hyperglycemia, insulin resistance, impaired glucose tolerance, and lethargy. The effects of a single injection have lasted through the 6-month course of the study. At all time points measured the circulating levels of leptin in the serum were similar to age-matched control C57 mice. These results demonstrate that maintenance of normal levels of leptin (2–5 ng/ml) in the circulation can prevent both the onset of obesity and associated non-insulin-dependent diabetes. Thus a single injection of a rAAV vector expressing a therapeutic gene can lead to complete and long-term correction of a genetic disorder. Our study demonstrates the long-term correction of a disease caused by a genetic defect and proves the feasibility of using rAAV-based vectors for the treatment of chronic disorders like obesity.

  7. Microstructural abnormalities in white and gray matter in obese adolescents with and without type 2 diabetes

    Directory of Open Access Journals (Sweden)

    Arie Nouwen

    Full Text Available Aims/hypotheses: In adults, type 2 diabetes and obesity have been associated with structural brain changes, even in the absence of dementia. Some evidence suggested similar changes in adolescents with type 2 diabetes but comparisons with a non-obese control group have been lacking. The aim of the current study was to examine differences in microstructure of gray and white matter between adolescents with type 2 diabetes, obese adolescents and healthy weight adolescents. Methods: Magnetic resonance imaging data were collected from 15 adolescents with type 2 diabetes, 21 obese adolescents and 22 healthy weight controls. Volumetric differences in the gray matter between the three groups were examined using voxel based morphology, while tract based spatial statistics was used to examine differences in the microstructure of the white matter. Results: Adolescents with type 2 diabetes and obese adolescents had reduced gray matter volume in the right hippocampus, left putamen and caudate, bilateral amygdala and left thalamus compared to healthy weight controls. Type 2 diabetes was also associated with significant regional changes in fractional anisotropy within the corpus callosum, fornix, left inferior fronto-occipital fasciculus, left uncinate, left internal and external capsule. Fractional anisotropy reductions within these tracts were explained by increased radial diffusivity, which may suggest demyelination of white matter tracts. Mean diffusivity and axial diffusivity did not differ between the groups. Conclusion/interpretation: Our data shows that adolescent obesity alone results in reduced gray matter volume and that adolescent type 2 diabetes is associated with both white and gray matter abnormalities.

    American Indian young adults have higher rates of obesity and type 2 diabetes than the general US population. They are also more likely than the general population to have higher rates of structural risk factors for obesity and diabetes, such as poverty, frequent changes of residence, and stress. The objective of this study was to investigate possible links between these 2 sets of problems. Data from the American Indian subsample of the National Longitudinal Study of Adolescent to Adult Health (Add Health) were used to examine potential links between obesity and type 2 diabetes and structural risk factors such as neighborhood poverty, housing mobility, and stress. We used logistic regression to explore explanatory factors. American Indians in the subsample had higher rates of poor health, such as elevated hemoglobin A1c levels, self-reported high blood glucose, self-reported diabetes, and overweight or obesity. They also had higher rates of structural risk factors than non-Hispanic whites, such as residing in poorer and more transient neighborhoods and having greater levels of stress. Self-reported stress partially mediated the increased likelihood of high blood glucose or diabetes among American Indians, whereas neighborhood poverty partially mediated their increased likelihood of obesity. Neighborhood poverty and stress may partially explain the higher rates of overweight, obesity, and type 2 diabetes among American Indian young adults than among non-Hispanic white young adults. Future research should explore additional neighborhood factors such as access to grocery stores selling healthy foods, proximity and safety of playgrounds or other recreational space, and adequate housing.

    To determine the prevalence of fibromyalgia in diabetes mellitus and obesity, 121 consecutive patients have been observed: 27 with obesity (6 males and 21 females; mean age 57 years, range 20-57; mean body mass index [BMI] 34); 88 with type 2 diabetes mellitus (T2DM; 40 males and 48 females; mean age 63 years, range 44-78; mean BMI 28.8; mean glycated haemoglobin [HbA1c] in the last year 8.3%); 6 with type 1 diabetes mellitus (T1DM; 2 males and 4 females; mean age 52 years, range 26-76; mean BMI 24.5; mean HbA1c BMI less that 26 the diagnosis of fibromyalgia was negative. Our data seem to reveal the presence of a significant clinical association between obesity, diabetes mellitus and fibromyalgia.

    Full Text Available Self-reported disability in performing daily life activities was assessed in adults with severe obesity (BMI ≥ 35 kg/m2 using the Health Assessment Questionnaire (HAQ. 262 participants were recruited into three BMI groups: Group I: 35–39.99 kg/m2; Group II: 40–44.99 kg/m2; Group III: ≥45.0 kg/m2. Progressively increasing HAQ scores were documented with higher BMI; Group I HAQ score: 0.125 (median (range: 0–1.75; Group II HAQ score: 0.375 (0–2.5; Group III HAQ score: 0.75 (0–2.65 (Group III versus II P 0. The prevalence of this degree of disability increased with increasing BMI and age. It also correlated to type 2 diabetes, metabolic syndrome, and clinical depression, but not to gender. Our data suggest that severe obesity is associated with self-reported disability in performing common daily life activities, with increasing degree of disability as BMI increases over 35 kg/m2. Functional assessment is crucial in obesity management, and establishing the disability profiles of obese patients is integral to both meet the specific healthcare needs of individuals and develop evidence-based public health programs, interventions, and priorities.

    The rate of obesity worldwide is currently at epidemic proportions. As part of obesity, the metabolic syndrome describes a clustering of metabolic abnormalities that increase the cardiovascular and diabetes risk. In particular, women from developing countries have diabetes in the reproductive age...... diabetes, hormonal contraception should therefore be part of the highly needed preconception care and metabolic control...

    Fasting and post-prandial abnormalities of adipose tissue (AT) lipoprotein lipase (LPL) and hormone- sensitive lipase (HSL) activities may have pathophysiological relevance in insulin-resistant conditions. The aim of this study was to evaluate activity and gene expression of AT LPL and HSL at fasting and 6 h after meal in two insulin-resistant groups - obese with Type 2 diabetes and obese without diabetes - and in non-diabetic normal-weight controls. Nine obese subjects with diabetes, 10 with obesity alone, and 9 controls underwent measurements of plasma levels of glucose, insulin, and triglycerides before and after a standard fat-rich meal. Fasting and post-prandial (6 h) LPL and HSL activities and gene expressions were determined in abdominal subcutaneous AT needle biopsies. The diabetic obese subjects had significantly lower fasting and post-prandial AT heparin-releasable LPL activity than only obese and control subjects (pobese subjects compared to controls in both fasting condition and 6 h after the meal (pfasting and 6 h after meal measurements in either LPL or HSL activities and gene expressions. Lipolytic activities in AT are differently altered in obesity and Type 2 diabetes being HSL alteration associated with both insulin-resistant conditions and LPL with diabetes per se. These abnormalities are similarly observed in the fasting condition and after a fat-rich meal.

    A population-based sample of Seventh-Day Adventists was studied to determine the relationship between vegetarian status, body mass index (BMI), obesity, diabetes mellitus (DM), and hypertension, in order to gain a better understanding of factors influencing chronic diseases in Barbados. A systematic sampling from a random start technique was used to select participants for the study. A standard questionnaire was used to collect data on demographic and lifestyle characteristics, to record anthropometrics and blood pressure measurements, and to ascertain the hypertension and diabetes status of participants. The sample population consisted of 407 Barbadian Seventh-Day Adventists (SDAs), who ranged in age from 25 to 74 years. One hundred fifty-three (37.6%) participants were male, and 254 (62.4%) were female, and 43.5% were vegetarians. The prevalence rates of diabetes and hypertension were lower among long-term vegetarians, compared to non-vegetarians, and long-term vegetarians were, on average, leaner than non-vegetarians within the same cohort. A significant association was observed between a vegetarian diet and obesity (vegetarian by definition P=.04, self-reported vegetarian P=.009) in this population. Other components of the study population lifestyle should be further analyzed to determine the roles they may plan in lessening the prevalence rates of obesity, diabetes, and hypertension.

    The assessment of the health consequences associated with obesity in young children is challenging. The aims of this study were: (1) to compare insulin resistance indices derived from OGTT in obese patients and healthy control (2) to analyze central obesity and Type 2 Diabetes genes expression in obese children, with special attention to the youngest group (10 years old). The study included 49 children with obesity (median age 13.5 years old), and 25 healthy peers. Biochemical blood tests and expression of 11 central obesity and 33 Type 2 Diabetes genes was assessed. A significant difference in insulin resistance between obese and non-obese adolescents was observed in all studied indices (mean values of the insulin levels: 24.9 vs. 9.71 mIU/L in T0, 128 vs. 54.7 mIU/L in T60 and 98.7 vs. 41.1 mIU/L in T120 respectively; AUC: 217 vs. 77.2 ng/ml*h, mean values of B% (state beta cell function), S% (insulin sensitivity), and IR were 255 (±97) vs. 135 (±37.8), 46.6 (±37.3) vs. 84.2 (±29.6) and 3 (±1.55) vs. 1.36 (±0,56); HIS, WBIS and ISIBel median 3.89, 44.7, 0.73 vs. 8.57, 110, 2.25. All comparisons differed significantly p1). Moreover, insulin sensitivity was significantly better in the older obese group (>10 years old): median AUC 239 vs. 104 ng/ml*h, and HIS, WBIS and ISIBel 3.57, 38, 0.67 vs. 6.23, 75.6, 1.87 respectively in the obese older compared to the obese younger subgroup, pobesity genes and 70% of Type 2 Diabetes genes was higher in the obese compared to control groups. The differences were more pronounced in the younger obese group. Insulin resistance may develop in early stage of childhood obesity and in very young children may be associated with higher expression of the central obesity and Type 2 Diabetes genes. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Diabetes mellitus type 2 is one of the leading chronic diseases in the world and in our country, which is an important risk factor for development of cardiovascular morbidity and mortality. Objective. The aim of this research was making the estimation of risk factors in the etiology of coronary heart disease in obese patients with diabetes mellitus type 2. The study included 82 obese patients, of which 52 with diabetes mellitus and 30 without diabetes mellitus, in all of them coronary artery disease proven by coronary angiography. All were examined by clinical examination, laboratory tests and echocardiography. Based on the test results we found that the distribution of risk factors such as hypertension, family burden coronary artery disease, smoking, alcohol intake was the same in the obese patients with diabetes mellitus, and of those without diabetes mellitus. Echocardiography showed significantly larger left ventricle, lower ejection fraction, larger left atrium and significant mitral regurgitation. Also, in a group of patients with diabetes mellitus, there was significantly higher number of patients with multiple vessel coronary disease. Despite the small sample, we can conclude that the present of diabetes mellitus in obese patients is crucial for severe forms of coronary artery disease. Severity is expressed through significant structural and functional changes in the left ventricle and the number of diseased coronary arteries.

    Childhood obesity has been linked to cardiovascular disease (CVD) risk in adulthood. Of great concern is the expected increase in the population's CVD burden in relation to childhood obesity. This is compounded by the risk related to chronic hyperglycemia exposure in youth with type 2 diabetes. We herein provide an overview of the spectrum of early cardiovascular disease manifestation in youth with obesity and type 2 diabetes, in particular abnormalities in cardiac structure and function. Cardiac remodeling and adverse target organ damage is already evident in the pediatric age group in children with obesity and type 2 diabetes. This supports the importance of intensifying obesity prevention efforts and early intervention to treat comorbidities of obesity in the pediatric age group to prevent cardiac events in early adulthood.

    Full Text Available Aim To verify the correlation between Retinol/RBP4 Ratio, and resistin with inflammation (represented by hsCRP in non-diabetic obese Indonesian menMethods This was a cross sectional study using 125 subjects. Measured parameters were retinol, RBP4, resistin, and hsCRP. Correlation between retinol, RBP4, resistin, hsCRP and Retinol/RBP4 Ratio was calculated. Cut off point of hsCRP were classiied as follows: <1 mg/l for low risk of inflammation, 1-3 mg/l for moderate risk, and 3-10 mg/l for high risk (according to CVD risk. The Retinol/RBP4 ratio was dichotomized into high (>0.9 and low ratio (≤0.9. The cross tabulation test was performed to predict the inflammation trends described by Retinol/RBP4 Ratio and resistin.Results Retinol was found strongly correlated with RBP4 and resistin (r=0.53; p<0.01. A positive but not significant correlation was found between resistin and Retinol/RBP4 Ratio with hsCRP. In high ratio group, 17.6% subjects were found with low risk inflammation, 26.4% with moderate risk, and 20.8% with high risk, in low ratio group, 8% subjects were low risk inflammation, 20% moderate risk, and 7.2% high risk. Combination between ratio and resistin showed that in “high ratio and low resistin” group, 12% subjects have low risk of inflammation and 8% have high risk. Meanwhile in “low ratio and high resistin” group, 3.2% subjects were found having low risk and 13.6% high risk of inflammation.Conclusions Combination between Retinol/RBP4 Ratio and resistin showed better description about the inflammation risk in non-diabetic obese subjects compare to the ratio itself.

    Obesity increases the risk of cardiovascular disease and diabetic complications in type 1 diabetes. Adipokines, which regulate obesity-induced inflammation, may contribute to this association. We compared serum adipokines and inflammatory cytokines in obese and lean children with new-onset autoimmune type 1 diabetes. We prospectively studied 32 lean and 18 obese children (age range: 2-18 yr) with new-onset autoimmune type 1 diabetes and followed them for up to 2 yr. Serum adipokines [leptin, total and high molecular weight (HMW) adiponectin, omentin, resistin, chemerin, visfatin], cytokines [interferon (IFN)-gamma, interleukin (IL)-10, IL-12, IL-6, IL-8, and tumor necrosis factor (TNF)-alpha] and C-reactive protein (CRP) were measured at a median of 7 wk after diagnosis (range: 3-16 wk). Lean children were 71.9% non-Hispanic White, 21.9% Hispanic, and 6.3% African-American, compared with 27.8, 55.6, and 16.7%, respectively, for obese children (p = 0.01). Compared with lean children, obese children had significantly higher serum leptin, visfatin, chemerin, TNF-alpha and CRP, and lower total adiponectin and omentin after adjustment for race/ethnicity and Tanner stage. African-American race was independently associated with higher leptin among youth ≥10 yr (p = 0.007). Leptin levels at onset positively correlated with hemoglobin A1c after 1-2 yr (p = 0.0001) independently of body mass index, race/ethnicity, and diabetes duration. Higher TNF-alpha was associated with obesity and female gender, after adjustment for race/ethnicity (p = 0.0003). Obese children with new-onset autoimmune type 1 diabetes have a proinflammatory profile of circulating adipokines and cytokines that may contribute to the development of cardiovascular disease and diabetic complications. © 2014 John Wiley & Sons A/S.

    Objective: To evaluate and compare the serum levels of visfatin, interleukin-6 and lipid profile in non-obese and obese male patients with coronary artery disease. Study Design: Observational, comparative study. Place and Duration of Study: Punjab Institute of Cardiology and Lahore General Hospital, Lahore, from July to December 2013. Methodology: The participants included 20 non-obese group I with coronary artery disease (CAD) and 20 obese males group II with coronary artery disease (angiographically confirmed). All the participants were in the age group of 35 - 55 years being non-smokers and non-diabetic. Serum visfatin and interleukin-6 levels were analysed by Enzyme Linked Immunosorbent Assay (ELISA). Lipid profile was also evaluated. Results were compared with T-test and Mann Whitney U test. The values were considered significant at 0.05 level of significance. Results: Serum visfatin 9.05 versus 3.9 ng/ml and interleukin-6 12.80 versus 0.60 pg/ml levels were significantly (p-value < 0.001 of both) raised in the obese CAD group as compared to non-obese with CAD. Lipid profile also showed raised levels of total serum cholesterol, low density lipoproteins, triglycerides, very low density lipoproteins and low levels of high density lipoproteins in obese group. Conclusion: Significantly raised levels of serum visfatin and interleukin-6 indicate adipose tissue as an imperative source of these adipocytokines involved in inflammation in CAD. Altered lipid profile also seen in obese patients with CAD. (author)

    Obesity, sleep apnea, diabetes and cardiovascular diseases are some of the most common diseases encountered by the worldwide population, with high social and economic burdens. Significant emphasis has been placed on obtaining blood pressure, body mass index, and placing importance on screening for signs and symptoms pointing towards cardiovascular disease. Symptoms related to sleep, or screening for sleep apnea has been overlooked by cardiac, diabetic, pulmonary and general medicine clinics despite recommendations for screening by several societies. In recent years, there is mounting data where obesity and obstructive sleep apnea sit at the epicenter and its control can lead to improvement and prevention of diabetes and cardiovascular complications. This editorial raises questions as to why obstructive sleep apnea screening should be included as yet another vital sign during patient initial inpatient or outpatient visit.

    Many obese children with unprovoked diabetic ketoacidosis (DKA) display clinical features of type 2 diabetes during follow up. We describe the clinical presentation, autoimmune markers and the long-term course of obese and lean children with DKA. We reviewed the medical records on the initial acute hospitalization and outpatient follow-up care of 21 newly diagnosed obese and 20 lean children with unprovoked DKA at Emory University affiliated children's hospitals between 1/2003 and 12/2006. Obese children with DKA were older and predominantly male, had acanthosis nigricans, and had lower prevalence of autoantibodies to islet cells and glutamic acid decarboxylase than lean children. Half of the obese, but none of the lean children with DKA achieve near-normoglycemia remission and discontinued insulin therapy during follow-up. Time to achieve remission was 2.2±2.3 months. There were no differences on clinical presentation between obese children who achieved near-normoglycemia remission versus those who did not. The addition of metformin to insulin therapy shortly after resolution of DKA resulted in lower hemoglobin A1c (HbA1c) levels, higher rates of near-normoglycemia remission, and lower frequency of DKA recurrence. Near-normoglycemia remission, however, was of short duration and the majority of obese patients required reinstitution of insulin treatment within 15 months of follow-up. In contrast to lean children with DKA, many obese children with unprovoked DKA display clinical and immunologic features of type 2 diabetes during follow-up. The addition of metformin to insulin therapy shortly after resolution of DKA improves glycemic control, facilitates achieving near-normoglycemia remission and prevents DKA recurrence in obese children with DKA.

    People with bipolar disorder or schizophrenia are at greater risk for obesity and other cardio-metabolic risk factors, and several prior studies have linked these risk factors to poorer cognitive ability. In a large ethnically homogenous outpatient sample, we examined associations among variables related to obesity, treated hypertension and/or diabetes and cognitive abilities in these two patient populations. In a study cohort of outpatients with either bipolar disorder (n = 341) or schizophrenia (n = 417), we investigated the association of self-reported body mass index and current use of medications for hypertension or diabetes with performance on a comprehensive neurocognitive battery. We examined sociodemographic and clinical factors as potential covariates. Patients with bipolar disorder were less likely to be overweight or obese than patients with schizophrenia, and also less likely to be prescribed medication for hypertension or diabetes. However, obesity and treated hypertension were associated with worse global cognitive ability in bipolar disorder (as well as with poorer performance on individual tests of processing speed, reasoning/problem-solving, and sustained attention), with no such relationships observed in schizophrenia. Obesity was not associated with symptom severity in either group. Although less prevalent in bipolar disorder compared to schizophrenia, obesity was associated with substantially worse cognitive performance in bipolar disorder. This association was independent of symptom severity and not present in schizophrenia. Better understanding of the mechanisms and management of obesity may aid in efforts to preserve cognitive health in bipolar disorder. © 2014 John Wiley & Sons A/S.

    Full Text Available Background: the incidence and prevalence of type 2 diabetes mellitus have increased in recent decades and this trend is expected to continue. Objective: to determine the risk perception for developing type 2 diabetes among non-diabetic individuals. Methods: a cross-sectional study involving non-diabetic individuals in the catchment area of the doctor-and-nurse office No.15 of the Manuel Fajardo Polyclinic in Cienfuegos was conducted between May 2013 and June 2014. The universe consisted of 1145 people, and the sample included 323 individuals of different age groups selected by sex. The variables studied were: age, sex, body mass index, nutritional assessment, and having a perceived risk when they answered 70 % of questions correctly. The arithmetic mean, standard deviation, Chi-square test, and risk estimation were calculated with a 95 % confidence interval. Results: individuals aged 25 to 34 years and females predominated. Fifty nine point two percent of the study participants knew of their risk. Eighty one point one percent understood that diabetes is preventable and 93.5 % stated that it is their responsibility to prevent its development. Thirty five point two percent of women considered normal-weight/thin fully agreed on the importance of physical activity and diabetes prevention. Eighty point five percent of women and 78.5 % of men answered positively to the question about obesity and diabetes. Conclusions: study participants knew of their risk of developing type 2 diabetes, although a large number of them attributed all responsibility for prevention to the health personnel.

    The literature about possible cardiovascular consequences of diagnostic inertia in diabetes is scarce. We examined the influence of undetected high fasting blood glucose (FBG) levels on the cardiovascular risk and poor control of cardiovascular risk factors in hypertensive or obese patients, with no previous diagnosis of diabetes mellitus (i.e., diagnostic inertia). A cross-sectional study during a preventive program in a Spanish region was performed in 2003-2004. The participants were aged ≥40 years and did not have diabetes but were hypertensive (n = 5, 347) or obese (n = 7, 833). The outcomes were high cardiovascular risk (SCORE ≥5%), poor control of the blood pressure (≥140/90 mmHg) and class II obesity. The relationship was examined between FBG and the main parameters, calculating the adjusted odd ratios with multivariate models. Higher values of FBG were associated with all the outcomes. A more proactive attitude towards the diagnosis of diabetes mellitus in the hypertensive and obese population should be adopted.

    To date, it is unknown whether reduced lipid oxidation of skeletal muscle of obese and obese type 2 diabetic (T2D) subjects partly is based on reduced oxidation of endogenous lipids. Palmitate (PA) accumulation, total oxidation and lipolysis were not different between myotubes established from lean...... both for endogenous and exogenous lipids. Thus myotubes established from obese and obese T2D subjects express a reduced complete oxidation of endogenous lipids. Two cardinal principles govern the reduced lipid oxidation in obese and diabetic myotubes; firstly, an impaired coupling between endogenous...... lipid and mitochondria in obese and obese diabetic myotubes and secondly, a mismatch between beta-oxidation and citric acid cycle in obese diabetic myotubes....

    Intra-abdominal liver biopsies were obtained during surgery from fasted obese patients with non-insulin-dependent diabetes mellitus (NIDDM), obese normoglycemic controls, and lean controls. Lipid synthesis was studied in freshly isolated hepatocytes and liver homogenates from the three groups of subjects. Incorporation of 3H2O into the lipids of hepatocytes was determined in the absence and presence of insulin (0.1 mumol/L). The activities of five enzymes involved in fatty acid synthesis, and the incorporation of 14C-glycerol-3-phosphate into lipids were determined in liver homogenates. Basal lipid synthesis by hepatocytes was not different in the three groups of patients. Insulin stimulated lipogenesis by 8% +/- 30% in the lean controls, 33% +/- 8% in the obese controls and 17% +/- 6% in the NIDDM patients. No significant differences in the activities of the five enzymes that are involved in de novo fatty acid synthesis among the three groups of patients were observed. Similarly, incorporation of 14C-glycerol-3-phosphate by liver homogenates, in the presence of saturating or submaximal concentrations of fatty acids, did not differ among the three groups. These results show that under the experimental conditions of this study, including the fasted state of the patients, the basal capacity of liver of NIDDM patients to synthesize fatty acids or glycerides is the same as that of liver from obese and lean controls. Thus, it is likely that an increase in fatty acid flux into a liver with normal lipogenic potential may contribute to the increased synthesis of triglycerides by the liver of these patients in vivo

    Obesity and diabetes family history are the two strongest risk factors for type 2 diabetes (T2D). Prior work shows that an individual's obesity risk is associated with obesity in social contacts, but whether T2D risk follows similar patterns is unknown. We aimed to estimate the relationship between obesity or diabetes in an individual's social contacts and his/her T2D risk. We hypothesized that obesity and diabetes in social contacts would increase an individual's T2D risk. This was a retrospective analysis of the community-based Framingham Offspring Study (FOS). FOS participants with T2D status, height and weight, and at least one social contact were eligible for this study (n = 4797 at Exam 1). Participants' interpersonal ties, cardiometabolic and demographic variables were available at eight exams from 1971 to 2008, and a T2D additive polygenic risk score was measured at the fifth exam. Primary exposures were T2D (fasting glucose ≥ 7 mmol/L or taking diabetes medications) and obesity status (BMI ≥ 30 kg/m(2)) of social contacts at a prior exam. Primary outcome was incident T2D in participants. Incident T2D was associated with having a social contact with diabetes (OR 1.32, p = 0.004) or with obesity (OR 1.21, p = 0.004). In stratified analyses, incident T2D was associated with diabetes in siblings (OR 1.64, p = 0.001) and obesity in spouses (OR 1.54, p = 0.0004). The associations between diabetes and obesity in social contacts and an individual's incident diabetes risk were stronger in individuals with a high diabetes genetic risk score. T2D and obesity in social contacts, particularly siblings and spouses, were associated with an individual's risk of incident diabetes even after accounting for parental T2D history. Assessing risk factors in an individual's siblings and spouses can inform T2D risk; furthermore, social network based lifestyle interventions involving spouses and siblings might be a novel T2D prevention approach.

    Over the past several decades, the United States has been experiencing a twin epidemic of obesity and type 2 diabetes. Recently, advocacy efforts to tax sugary drinks, place warning labels on soda, improve nutritional labeling, and reduce sugar overconsumption have swept across the nation to address public health concerns from sugary drinks that strain our nation's health-care resources. In this article, the historical and scientific framework of this public health policy and valuable lessons learned from implementation efforts thus far will be examined to shape the next steps forward for the movement. Additional goals of this article are to share a surgeon's perspective about trends in bariatric surgery and the link between obesity and type 2 diabetes as a result of peripheral insulin resistance.

    Obesity has been associated with greater severity of influenza virus infection and impaired host defense. Exercise may confer health benefits even when weight loss is not achieved, but it has not been determined if regular exercise improves immune defense against influenza A virus (IAV) in the obese condition. In this study, diet-induced obese mice and lean control mice exercised for eight weeks followed by influenza viral infection. Exercise reduced disease severity in both obese and non-obese mice, but the mechanisms differed. Exercise reversed the obesity-associated delay in bronchoalveolar-lavage (BAL) cell infiltration, restored BAL cytokine and chemokine production, and increased ciliary beat frequency and IFNα-related gene expression. In non-obese mice, exercise treatment reduced lung viral load, increased Type-I-IFN-related gene expression early during infection, but reduced BAL inflammatory cytokines and chemokines. In both obese and non-obese mice, exercise increased serum anti-influenza virus specific IgG2c antibody, increased CD8+ T cell percentage in BAL, and reduced TNFα by influenza viral NP-peptide-responding CD8+ T cells. Overall, the results suggest that exercise “restores” the immune response of obese mice to a phenotype similar to non-obese mice by improving the delay in immune activation. In contrast, in non-obese mice exercise treatment results in an early reduction in lung viral load and limited inflammatory response. PMID:26110868

    Full Text Available Abstract Background The endocannabinoids, anandamide and 2-AG, are produced by adipocytes, where they stimulate lipogenesis via cannabinoid CB1 receptors and are under the negative control of leptin and insulin. Endocannabinoid levels are elevated in the blood of obese individuals and nonobese type 2 diabetes patients. To date, no study has evaluated endocannabinoid levels in subcutaneous adipose tissue (SAT of subjects with both obesity and type 2 diabetes (OBT2D, characterised by similar adiposity and whole body insulin resistance and lower plasma leptin levels as compared to non-diabetic obese subjects (OB. Design and Methods The levels of anandamide and 2-AG, and of the anandamide-related PPARα ligands, oleoylethanolamide (OEA and palmitoylethanolamide (PEA, in the SAT obtained by abdominal needle biopsy in 10 OBT2D, 11 OB, and 8 non-diabetic normal-weight (NW subjects, were measured by liquid chromatography-mass spectrometry. All subjects underwent a hyperinsulinaemic euglycaemic clamp. Results As compared to NW, anandamide, OEA and PEA levels in the SAT were 2-4.4-fold elevated (p Conclusions The observed alterations emphasize, for the first time in humans, the potential different role and regulation of adipose tissue anandamide (and its congeners and 2-AG in obesity and type 2 diabetes.

    NTproBNP and BNP levels are reduced in obese subjects, but population-based data comparing the pattern of this relationship in the full spectrum of insulin-resistance mediated conditions, overweight/obesity, metabolic syndrome and diabetes, are limited. The study-base were 3244 individuals aged 45-74 years, none of whom had heart failure, 1880 without diabetes and 1364 with diabetes, identified as part of two surveys of the population-based Casale Monferrato Study. All measurements were centralized. We examined with multiple linear regression and cubic regression splines the relationship between NTproBNP and BMI, independently of known risk factors and confounders. A logistic regression analysis was also performed to assess the effect of overweight/obesity (BMI ≥ 25 kg/m 2 ), diabetes and metabolic syndrome on NTproBNP values. Out of the overall cohort of 3244 people, overweight/obesity was observed in 1118 (59.4%) non-diabetic and 917 (67.2%) diabetic subjects, respectively. In logistic regression, compared to normal weight individuals, those with a BMI ≥ 25 kg/m 2 had a OR of 0.70 (95% CI 0.56-0.87) of having high NTproBNP values, independently of diabetes. As interaction between diabetes and NTproBNP was evident (p obesity or metabolic syndrome enhanced fourfold and over the OR of having high NTproBNP levels, while the presence of metabolic syndrome alone had a more modest effect (OR 1.54, 1.18-2.01) even after having excluded individuals with CVD. In the non-diabetic cohort, obesity/overweight and HOMA-IR ≥ 2.0 decreased to a similar extent the ORs of high NTproBNP [0.76 (0.60-0.95) and 0.74 (0.59-0.93)], but the association between overweight/obesity and NTproBNP was no longer significant after the inclusion into the model of HOMA-IR, whereas CRP > 3 mg/dl conferred a fully adjusted OR of 0.65 (0.49-0.86). NT-proBNP levels are lower in overweight/obesity, even in those with diabetes. Both insulin-resistance and chronic low-grade inflammation

    Insulin resistance is positively correlated with body iron. It is unclear whether iron is a cause or an outcome of insulin resistance. Insulin resistance precedes type 2 diabetes mellitus. Offspring of type 2 diabetics are insulin resistant as compared to those of the non-diabetics. The present study was designed to compare and correlate insulin resistance with iron parameters (including serum ferritin, transferrin saturation and blood haemoglobin) in non-diabetic offspring of type 2 diabetics and non-diabetic offspring of non-diabetics. Methods: It was a cross-sectional study, conducted on one hundred and twenty male subjects 20-40 years of age. They were divided into two groups, each group having 60 subjects. Group A included non-diabetic offspring of type 2 diabetics, while Group B included non-diabetic offspring of non-diabetics. Fasting blood sample was taken and examined for glucose, haemoglobin, insulin, iron, TIBC and ferritin. Data was analysed by SPSS-17. Results: Insulin resistance and iron parameters were significantly higher (p<0.05) in non-diabetic offspring of type 2 diabetics as compared to those of the non-diabetics. There was significant positive correlation (p=0.027) between insulin resistance and serum iron in non-diabetic offspring of type 2 diabetics. There was also significant positive correlation between insulin resistance and serum iron, transferrin saturation and haemoglobin in non-diabetic offspring of non-diabetics. Conclusion: Non-diabetic offspring of type 2 diabetics have iron load and insulin resistance, that predispose them to the development of type 2 diabetes. (author)

    Objective: To assess the relationship of severity of coronary artery disease with obesity in patients undergoing coronary angiography. Design: Cross sectional study. Place and Duration of Study: Armed Forces Institute of Cardiology - National Institute of Heart Diseases (AFIC-NIHD), 1st February 2010 to 31st August 2010 Patients and Methods: The study population included 468 patients undergoing coronary angiography. Obesity was classified according to the BMI using the National Institutes of Health (NIH) criteria as normal (BMI 21-24 kg/m2), overweight (BMI 25-29 kg/m2), obesity class I (BMI 30-34 kg/m2), obesity class II (BMI 35 to 39 kg/m2 and obesity class III (BMI 40 or above kg/m2). Coronary angiography data were obtained from the Siemens Queries software system, which maintains the database including detailed angiographic findings of all patients at this institution. Significant lesions were defined as those with >70% diameter narrowing of coronary arteries (>50% for the left main coronary artery). We attempted to quantify the 'severity of CAD' by ascertaining the prevalence of High-Risk Coronary Anatomy (HRCA). Results: Insignificant difference was observed in traditional risk factors i.e. age, diabetes mellitus and smoking except hypertension and gender. Statistically significantly low prevalence of HRCA was encountered in the obese group (57.7%) as compared to normal/overweight group (75.8%) (p < 0.05). Conclusion: We conclude that obesity is associated with less severe coronary artery disease. (author)

    Overweight children are growing problem as in the pediatric, as well in the diabetic population. The aim of the study was to research the percentage of overweight and obesity in a group of adolescents with type 1 diabetes, and to analyzethe lipid parameters, as well risk factors of these abnormalities. The study group consist of 60 type 1 diabetic adolescents (including 32 girls, 53.3%), aged above 12 years (mean age for girls 14.6+/-0,3years, boys 15.6+/-0.4 years) with diabetes duration (girls 5.7+-0.6 years, boys 4.4+/-0.8 years). Statistical analysis was performed using Statistica v 9.0 and SPSS v20. The study revealed that boys with type 1 diabetes are significantly higher than healthy population, with weight, waist circumference and BMI comparable to the healthy counterparts. However, diabetic girls are more likely to be overweight and have bigger waist circumference, and higher BMI than the healthy population. Overweight were 12 adolescents (20%) using BMI ≥1SD criterion, and 10 (16%) using waist circumference as obesity parameter. Logistic regression revealed that the most important factors for obesity and abdominal obesity are female gender (OR=2.43 and OR=4.56for obesity and abdominal, respectively), diabetes duration above 5 years (respectively OR=1.96 and OR=3.27) and poor metabolic control (respectively OR=1.74 and OR=2.89). The most important risk factor for obesity in adolescents with type 1 diabetes is female gender. Lipids profile is closely dependent on metabolic control and mass excess. Diabetes duration, metabolic control and lipids profile are significant risk factors for overweight and abdominal obesity. © Polish Society for Pediatric Endocrinology and Diabetology.

    Obesity and diabetes are major public health problems throughout the World. Obese individuals body mass index (BMI) is >30 kg/m2. Obesity is characterized by increased waist circumference, total body fat and hyperglycemia. The increased triglyceride and cholesterol level is also shown in obese individuals. The development of obesity is largely due to the consumption of high energy food and sedentary lifestyle. This study was held with the participation of patients applied to Siirt State Hospital endocrine policlinic for treatment. Our aim is to try to determine the biochemical relation and border line of obese and obese+diabetes mellitus patients. Patients and control group lipid profiles were studied in the hospital biochemisty laboratory. Laboratory results of diabetes+obese, obese and control groups were evaluated. Patients and control samples blood serum levels were compared according to their lipid profiles. In 2015, 735 diabetes mellitus type 2 patients applied to Endocrine polyclinic. Some of these patient's serum levels were evaluated. Difference between diabetes+obese and diabetes groups were near critical level for LDL and trigliserid. There were not observed statistically significant difference between groups in terms of HDL and cholesterol. There were found significant difference between groups for blood glucose p<0.003, age p<0.001. According to gender between women and men serum levels, ALT and AST levels; p<0.006 and cholesterol; p<0.04 were detected. According to participants education level blood biochemistry levels were observed statisticaly different p<0.001 with non-literacy group. In conclusion, obese and obese+diabetes patients blood serum values nearly close to each other. Obese subjects were been diabetic obese with age. In women obesity and diabetes mellitus prevalence were seen too much.

    Full Text Available BACKGROUND: MicroRNAs (miRNAs are small regulatory RNAs that play important roles in development of diseases. Several studies have provided evidences showing that miRNAs affect pathways that are fundamental for metabolic control in adipocyte and skeletal muscle differentiations. Some miRNAs have been implicated in lipid, amino acid, and glucose homeostasis. This leads to the possibility that miRNAs may contribute to common metabolic diseases and point to novel therapeutic opportunities based on targeting of miRNAs. CONTENT: miRNAs have been recognized as a class of epigenetic regulators of metabolism and energy homeostasis, primarily because the simultaneous regulation of a large number of target genes can be accomplished by a single miRNA. Emerging evidences suggest that miRNAs play a key role in the pathological development of obesity by affecting adipocyte differentiation. miRNAs have been implicated as novel protagonists in the pathogenesis of Diabetes Mellitus (DM, regulation of insulin production, secretion and action. They also appear to play a role in the development of diabetic complications such as nephropathy and cardiac hypertrophy. SUMMARY: Involvement of miRNAs in glucose and lipid metabolism has provided strong evidences to confirm their roles as key players in regulation of complex metabolic pathways. Additionally, it indicates potential outlook for novel therapeutic strategies in the management of obesity, metabolic syndrome and DM. Further research in this field is needed to ascertain the full potential of miRNAs as novel metabolic biomarkers and potent therapeutic agents against obesity and its metabolic disorders. KEYWORDS: obesity, metabolic syndrome, diabetes, miRNAs, adipogenesis, insulin, pancreatic cells.

    Full Text Available Vitamin B12 and folate are critical micronutrients needed to support the increased metabolic demands of pregnancy. Recent studies from India have suggested that low vitamin B12 and folate concentrations in pregnancy are associated with increased obesity; however differences in diet, antenatal vitamin supplementation, and socioeconomic status may limit the generalisability of these findings. We aimed to explore the cross-sectional relationship of circulating serum vitamin B12 and folate at 28 weeks' gestation with maternal adiposity and related biochemical markers in a white non diabetic UK obstetric cohort.Anthropometry and biochemistry data was available on 995 women recruited at 28 weeks gestation to the Exeter Family Study of Childhood Health. Associations between B12 and folate with maternal BMI and other obesity-related biochemical factors (HOMA-R, fasting glucose, triglycerides, HDL and AST were explored using regression analysis, adjusting for potential confounders (socioeconomic status, vegetarian diet, vitamin supplementation, parity, haemodilution (haematocrit.Higher 28 week BMI was associated with lower circulating vitamin B12 (r = -0.25; P<0.001 and folate (r = -0.15; P<0.001. In multiple regression analysis higher 28 week BMI remained an independent predictor of lower circulating B12 (β (95% CI = -0.59 (-0.74, -0.44 i.e. for every 1% increase in BMI there was a 0.6% decrease in circulating B12. Other markers of adiposity/body fat metabolism (HOMA-R, triglycerides and AST were also independently associated with circulating B12. In a similar multiple regression AST was the only independent obesity-related marker associated with serum folate (β (95% CI = 0.16 (0.21, 0.51.In conclusion, our study has replicated the previous Indian findings of associations between lower serum B12 and higher obesity and insulin resistance during pregnancy in a non-diabetic White British population. These findings may have important implications for

    Diabetes remission is not observed in all obese patients with type 2 diabetes submitted to bariatric surgery. Relapses occur in patients in whom remission is achieved. We investigated the factors associated with long-term (≥3 years) remission and relapse of type 2 diabetes after Roux-en-Y gastric bypass (RYGB) in these patients. By a retrospective review, we analyzed data from 254 patients with type 2 diabetes who had undergone RYGB from May 2000 to November 2011 and had at least 3 years of follow-up. The criteria for remission and relapse of type 2 diabetes followed the current American Diabetes Association recommendations. Remission was achieved in almost 82% of participants (69.7% complete, and 12.2% partial remission). Of these, 12% relapsed within a mean follow-up of 5.1 ± 2.0 years after surgery. Predictors of complete remission were younger age, better preoperative glycemic control, and shorter diabetes duration. Preoperative insulin use was associated with a ninefold increase in the relapse hazard (HR = 9.1 (95% CI: 3.3-25.4)). Use of two or more oral anti-diabetic agents increased the relapse hazard sixfold (HR = 6.1 (95% CI: 1.8-20.6)). Eighteen point one percent of patients did not achieve any remission during follow-up. However, they exhibited significant improvements in glycemic control. These data indicate that RYGB should not be delayed when remission of type 2 diabetes is a therapeutic goal, and also suggest that the best possible metabolic control should be sought in obese patients who may eventually be candidates for RYGB.

    To investigate the relationship between anthropometric parameters and diabetic retinopathy (DR) in adults with diabetes. Five hundred participants with diabetes were recruited prospectively from ophthalmology clinics in Melbourne, Australia. Each underwent an eye examination, anthropometric measurements, and standardized interview-administered questionnaires, and fasting blood glucose and serum lipids were analyzed. Two-field fundus photographs were taken and graded for DR. Height; weight; body mass index (BMI); waist, hip, neck, and head circumferences; and skinfold measurements were recorded. A total of 492 patients (325 men, 66.1%) aged between 26 and 90 years (median, 65) were included in the analysis: 171 (34.8%), 187 (38.0%), and 134 (27.2%) with no DR, nonproliferative DR (NPDR), and proliferative DR (PDR), respectively. After multiple adjustments, higher BMI (odds ratio [OR], 1.06; 95% confidence interval [CI],1.01-1.11; P = 0.02) was significantly associated with any DR. Obese people were 6.5 times more likely to have PDR than were those with normal weight (OR, 6.52; 95% CI, 1.49-28.6; P = 0.013). Neck circumference (OR, 1.05; 95% CI, 1.00-1.10; P = 0.03) and waist circumference (OR, 1.12; 95% CI, 1.03-1.22; P = 0.01) were significantly associated with any DR. BMI (OR, 1.04; 95% CI, 1.00-1.08; P = 0.04) and neck circumference (OR, 1.04 95% CI, 1.01-1.08; P = 0.04) were also positively associated with increasing severity levels of DR. Persons with diabetes with higher BMI and larger neck circumference are more likely to have DR and more severe stages of DR. These data suggest that obesity is an independent risk factor for DR.

    Interventions for prevention of type 2 diabetes ought to be acceptable to target communities. We assessed perceptions about type 2 diabetes and lifestyle change among people afflicted or at high risk of this disease in a low income setting in Iganga Uganda. Twelve focus group discussions (FGDs) of eight participants each were conducted, balancing rural and peri-urban (near the Municipality) residence and gender. The FGDs involved people with suspected type 2 diabetes (based on fasting plasma glucose (FPG), people with suspected pre-diabetes and obese people with normal FPG. Content analysis was conducted. Diabetes was perceived to be a very severe disease. Its severity was attributed to its incurability and its numerous health effects. Men were also concerned about reduced sexual performance. However, participants' strong concerns about the severity of diabetes were not reflected in their perceptions about the risk factors and lifestyles associated with it. While people with diabetes perceive obesity as 'sickness', those without diabetes perceive it as a sign of 'success'. Although participants are willing to change their diet, they mention numerous barriers including poverty, family size, and access to some foods. Because of their good taste, reduction of high risk foods like sugar and fried food is perceived as 'sacrificing a good life'. Increments in physical activity were said to be feasible, but only in familiar forms like domestic work. An over-arching theme emerged that 'lifestyle changes are viewed as sacrificing a good life'. Health promotion should target both community norms and individual awareness regarding obesity, physical activity and diet, and should address the notion that obesity and unhealthy foods represent a good life. Health educators should plan with clients on how to overcome barriers and misconceptions to lifestyle change, leveraging the pervasive perception of type 2 diabetes as a severe disease to motivate change.

    Arterial baroreceptors play an important role in the short-term regulation of arterial pressure, by reflex chronotropic effect on the heart and by reflex regulation of sympathetic outflow. Baroreflex sensitivity (BRS) represents an index of arterial baroreceptors function. Several methods of measuring BRS are available nowadays. Different factors influence BRS in the healthy population, including sex, age, blood pressure, heart rate, body fatness, arterial stiffness, blood glucose and insulin levels, as well as physical activity. Baroreceptors dysfunction is evident in diseases such as coronary artery disease, heart failure, arterial hypertension, diabetes mellitus and obesity. The underlying mechanism of BRS attenuation in diabetes or obesity is not yet well known; however, there is increasing evidence that it is at least partly related to autonomic nervous system dysfunction and particularly to sympathetic overactivity that accompanies these diseases. Blunted BRS provides prognostic information for cardiovascular diseases and possibly for diabetes, while its' prognostic information for obesity is not yet established. This review deals with the mechanisms affecting baroreflex function, the newer techniques of BRS estimation and the most recent insights of baroreflex function in the healthy population and in various diseases with emphasis on diabetes and obesity. In addition, the clinical implication of a reduced BRS in these disorders is discussed.

    In recent years, obesity and diabetes have become the epidemic mainly due to fast food and lifestyle changes. Several herbs have been claimed to control diabetes and obesity. However, there are a few which control both. Our aim was to evaluate the anti-diabetic and anti-obesity activity of methanolic extract of Memecylon umbellatum (MU) in alleviation of insulin resistance (IR). Diet induced obese (DIO) mice model was developed by feeding the mice on high fat diet (HFD) for 10 weeks resulting in hyperglycemia, obesity and IR. 250mg/kg body weight of extract was administered orally daily for 8 weeks. Fasting glucose and body weight were monitored throughout the experiment. At the end of the study, serum parameters, histological examinations and gene expression pattern were analyzed. There was a significant reduction in fasting glucose levels, body weight and triglycerides. Improvement in the glucose tolerance and amelioration of insulin resistance was observed as revealed by reduction in serum IL6, serum oxidised LDL, histological sections of liver and subcutaneous adipose. Gene expression studies demonstrated the anti-inflammatory activity of the extract by down regulating IL6, PAI1 and ApoB gene expression as compared to the untreated HFD control. Our results demonstrate for the first time that oral administration of methanolic extract of MU in DIO mice leads to reduction in hyperglycemia, body weight, triglycerides and ameliorates insulin resistance. Further, mechanism of action of the extract needs to be investigated by purifying the extract and analyzing the active ingredient playing the major role. Copyright © 2017 Elsevier Masson SAS.

    Full Text Available Background. Age-related loss of muscle mass (sarcopenia increases the incidence of obesity in the elderly by reducing physical activity. This sarcopenic obesity may become self-perpetuating, increasing the risks for metabolic syndrome, disability, and mortality. We investigated the associations of two sarcopenic indices, the ratio of lower extremity muscle mass to body weight (L/W ratio and the ratio of lower extremity muscle mass to upper extremity muscle mass (L/U ratio, with metabolic parameters related to obesity in patients with type 2 diabetes and obesity.Methods. Of 148 inpatients with type 2 diabetes treated between October 2013 and April 2014, we recruited 26 with obesity but no physical disability. Daily physical activity was measured by a triaxial accelerometer during a period of hospitalization, and which was also evaluated by our previously reported non-exercise activity thermogenesis questionnaire. We measured body composition by bioelectrical impedance and investigated the correlations of L/W and L/U ratios with body weight, body mass index (BMI, waist circumference (WC, waist-to-hip ratio (WHR, visceral fat area, subcutaneous fat area, serum lipid profile, and daily physical activity.Results. The L/W ratio was significantly and negatively correlated with BMI, WC, WHR, body fat mass, body fat percentage, subcutaneous fat area, and serum free fatty acid concentration, was positively correlated with daily physical activity: the locomotive non-exercise activity thermogenesis score, but was not correlated with visceral fat area. The L/U ratio was significantly and positively correlated with serum high-density lipoprotein cholesterol.Conclusions. High L/W and L/U ratios, indicative of relatively preserved lower extremity muscle mass, were predictive of improved metabolic parameters related to obesity. Preserved muscle fitness in obesity, especially of the lower extremities, may prevent sarcopenic obesity and lower associated risks for

    Type 2 diabetes (T2DM) is associated with significant morbidity and mortality. Obesity is one of the main risk factors for T2DM and its management requires a multidisciplinary approach, which may include pharmacotherapy. Areas covered: In this paper, data on efficacy, tolerability and safety of FDA-approved pharmacotherapies for obesity (orlistat, phentermine/topiramate extended-release, lorcaserin, bupropion sustained release/naltrexone sustained release and liraglutide) are reviewed, focusing on individuals with type 2 diabetes. Expert opinion: Obesity is the major pathophysiologic driver of T2DM; conversely 5-10% weight loss leads to significant improvement in glycemic control, lipids and blood pressure. Weight loss maintenance is difficult with lifestyle interventions alone and may require adjunctive therapies. There is good evidence for the efficacy and tolerability of approved anti-obesity pharmacotherapies in individuals with T2DM, with current cardiovascular safety data being most favorable for liraglutide, orlistat and lorcaserin. Given the link between obesity and T2DM, a weight-centric therapeutic approach including use of weight reducing anti-diabetic therapies, and anti-obesity pharmacotherapies is both intuitive and rational to improve glycemic and other metabolic outcomes in patients with T2DM.

    The lack of physical activity, along with obesity, smoking, hypertension and hyperglycaemia are considered as risk factors for the occurrence of diseases such as diabetes. Primary objective of the study was to investigate potential correlation between physical activity and diabetic retinopathy. Three hundred and twenty patients were included in the study: 240 patients with diabetes type 2 (80 patients with mild to moderate non-proliferative diabetic retinopathy, 80 patients with severe to very severe non-proliferative diabetic retinopathy and 80 ones with proliferative diabetic retinopathy) were compared with 80 non-diabetic patients (control group). Physical activity of patients was assessed by the international physical activity questionnaire (IPAQ, 2002). HbA1c and BMI were also measured in diabetic patients. Group comparisons were attempted for levels of physical activity and sedentary behavior. Total physical activity was decreased in patients with severe to very severe non-proliferative diabetic retinopathy and proliferative diabetic retinopathy as compared to patients with mild to moderate non-proliferative diabetic retinopathy and to the control group (pdiabetic retinopathy and physical activity has been demonstrated (pdiabetic retinopathy, independent of the effects of HbA1c and BMI.

    2016-04-01

    India is witnessing an increase in the burden of childhood obesity, especially among the upper socioeconomic strata and in urban areas. Emerging literature suggests a link between childhood obesity and the diabetes epidemic in India. Asian-Indian children and adolescents are increasingly susceptible to a high percentage of body fat and abdominal adiposity. Further, they are exposed to an obesogenic environment, created by rapid urbanization and nutrition transition in India. Obese children have a higher risk of developing abnormalities that are recognized as precursors to diabetes, such as subclinical inflammation, insulin resistance and metabolic syndrome, which often track to adulthood. A review of the literature suggests the need for more longitudinal studies to improve understanding of the long-term consequences of childhood obesity in India. A life-course approach with a combination of population- and risk-based strategies is warranted, to prevent childhood obesity and curtail its consequences in adulthood.

    The prevalence of obesity has risen dramatically and the World Health Organization estimates that 700 million people will be obese worldwide by 2015. Approximately, 50% of the Brazilian population above 20 years of age is overweight, and 16% is obese. This study aimed to evaluate the differences in the expression of PPARα target genes in human peripheral blood mononuclear cells (PBMCs) and free fatty acids (FFA) in obese and non-obese individuals after 24 h of fasting. We first presented evidence that Brazilian people exhibit expression changes in PPARα target genes in PBMCs under fasting conditions. Q-PCR was utilized to assess the mRNA expression levels of target genes. In both groups, the FFA concentrations increased significantly after 24 h of fasting. The basal FFA mean concentration was two-fold higher in the obese group compared with the non-obese group. After fasting, all genes evaluated in this study showed increased expression levels compared with basal expression in both groups. However, our results reveal no differences in gene expression between the obese and non-obese, more studies are necessary to precisely delineate the associated mechanisms, particularly those that include groups with different degrees of obesity and patients with diabetes mellitus type 2 because the expression of the main genes that are involved in β-oxidation and glucose level maintenance are affected by these factors. © 2014 S.

    Adiponectin (ADN), an insulin-sensitizing adipokine, stimulates glucose uptake, inhibits gluconeogenesis, and plays an important role in improving insulin sensitivity. Since blood levels of ADN are low in type 2 diabetes mellitus (DM), this study was designed to investigate the therapeutic effectiveness of increasing the ADN level through injection of plasmid DNA encoding ADN in type 2 DM. A non-obese type 2 DM mouse model was established via combined administration of streptozotocin with nicotinamide and exhibited significantly higher plasma glucose concentration and insulin resistance compared with normal controls according to oral glucose tolerance and insulin challenge tests. Plasmid DNA encoding mouse ADN from differentiated NIH3T3 adipocytes was constructed in pVAX1 (pVAX/ADN). Transfection of pVAX/ADN into various cell lines including HeLa, HT22, HEK293, HepG2, and SK-Hep1 cells, increased ADN mRNA expression levels in a dose-dependent manner. The administration of pVAX/ADN into non-obese type 2 DM mice via tail vein significantly increased the blood level of ADN and decreased the plasma glucose concentration. Moreover, the parameters related to insulin resistance (HOMA-IR) and insulin sensitivity (QUICKI) were significantly improved. These results suggest that ADN gene therapy could be a clinically effective tool for the treatment of type 2 DM.

    Background: Increased body weight is a major risk factor for the metabolic syndrome which is a cluster of coronary heart disease risk factors, like: hypertension, diabetes mellitus and dyslipidaemia. This study was conducted to determine the frequency of abdominal obesity and diabetes mellitus in the population of Peshawar and association between them. Method: This was a cross sectional study, performed by the Cardiology Department, Lady Reading Hospital Peshawar, in the population of Peshawar. All participants were interviewed in detail regarding known risk factors for coronary artery disease. Waist circumference (=102 cm in male and =88 cm in females) was used as the surrogate marker for abdominal obesity in already diagnosed patients of type-2 diabetes mellitus. Results: A total of 2548 individuals were included, 71.1 percentage were male. Mean age was 37.94±12.59 years. Mean waist circumference was 90.25±13.4 5cm in males and 90.52±12.52 cm in females. Diabetes was present in 4.4 percentage of the participants and abdominal obesity in 56.6 percentage Among the male, abdominal obesity was present in 39.4 percentage and diabetes in 2.9 percentage. Out of 39.4 percentage males with abdominal obesity, 2 percentage were diabetic. Out of 38.6 percentage males with no abdominal obesity, 0.9 percentage was diabetic. Amongst the total 559 (21.1 percentage) female subjects, 17.2 percentage were having abdominal obesity and 1.4 percentage was diabetics. Among 123 (4.8 percentage) females with no abdominal obesity, 0.1 percentage was diabetic. A positive association was established between abdominal obesity and diabetes mellitus with a significant p-valve (<0.05). Conclusion: Abdominal obesity is more common in the local population of Peshawar and associated with type-2 diabetes mellitus. (author)

    In this large registry-based study, women with diabetes had marginally greater bone mineral density (BMD) loss at the femoral neck but not at other measurement sites, whereas obesity was not associated with greater BMD loss. Our data do not support the hypothesis that rapid BMD loss explains the increased fracture risk associated with type 2 diabetes and obesity observed in prior studies. Type 2 diabetes and obesity are associated with higher bone mineral density (BMD) which may be less protective against fracture than previously assumed. Inconsistent data suggest that rapid BMD loss may be a contributing factor. We examined the rate of BMD loss in women with diabetes and/or obesity in a population-based BMD registry for Manitoba, Canada. We identified 4960 women aged ≥ 40 years undergoing baseline and follow-up BMD assessments (mean interval 4.3 years) without confounding medication use or large weight fluctuation. We calculated annualized rate of BMD change for the lumbar spine, total hip, and femoral neck in relation to diagnosed diabetes and body mass index (BMI) category. Baseline age-adjusted BMD was greater in women with diabetes and for increasing BMI category (all P obese women but BMI did not significantly affect hip BMD loss.

    Previously, we found that bis(allixinato)oxovanadium(IV) (VO(alx) 2 ) exhibits a potent hypoglycemic activity in type 1-like diabetic mice. Since the enhancement of insulin sensitivity is involved in one of the mechanisms by which vanadium exerts its anti-diabetic effects, VO(alx) 2 was further tested in type 2 diabetes with low insulin sensitivity. The effect of oral administration of VO(alx) 2 was examined in obesity-linked type 2 diabetic KKA y mice. Treatment of VO(alx) 2 for 4 weeks normalized hyperglycemia, glucose intolerance, hyperinsulinemia, hypercholesterolemia and hypertension in KKA y mice; however, it had no effect on hypoadiponectinemia. VO(alx) 2 also improved hyperleptinemia, following attenuation of obesity in KKA y mice. This is the first example in which a vanadium compound improved leptin resistance in type 2 diabetes by oral administration. On the basis of these results, VO(alx) 2 is proposed to enhance not only insulin sensitivity but also leptin sensitivity, which in turn improves diabetes, obesity and hypertension in an obesity-linked type 2 diabetic animal

    Nutrition, especially wheat consumption, is a major factor involved in the onset of type 1 diabetes (T1D) and other autoimmune diseases such as celiac. While modern wheat cultivars possess similar gliadin proteins associated with the onset of celiac disease and T1D, alternative dietary wheat sources from Israeli landraces and native ancestral species may be lacking the epitopes linked with T1D, potentially reducing the incidence of T1D. The Non-Obese Diabetic (NOD) mouse model was used to monitor the effects of dietary wheat sources on the onset and development of T1D. The effects of modern wheat flour were compared with those from either T. aestivum , T. turgidum spp. dicoccoides , or T. turgidum spp. dicoccum landraces or a non-wheat diet. Animals which received wheat from local landraces or ancestral species such as emmer displayed a lower incidence of T1D and related complications compared to animals fed a modern wheat variety. This study is the first report of the diabetogenic properties of various dietary wheat sources and suggests that alternative dietary wheat sources may lack T1D linked epitopes, thus reducing the incidence of T1D.

    Obesity and motor vehicle crash (MVC) injuries are two parallel epidemics in the United States. An important unanswered question is whether there are sex differences in the associations between the presence of obesity and non-fatal MVC injuries. To further understand the association between obesity and non-fatal MVC injuries, particularly the sex differences in these relations. We examined this question by analyzing data from the 2003 to 2007 National Automotive Sampling System Crashworthiness Data System (NASS CDS). A total of 10,962 drivers who were aged 18 years or older and who survived frontal collision crashes were eligible for the study. Male drivers experienced a lower rate of overall non-fatal MVC injuries than did female drivers (38.1 versus 52.2%), but experienced a higher rate of severe injuries (0.7 versus 0.2%). After adjusting for change in velocity (ΔV) during the crashes, obese male drivers showed a much higher risk (logistic coefficients of body mass index (BMI) for moderate, serious and severe injury are 0.0766, 0.1470 and 0.1792, respectively; all Pobese male drivers and these risks increased with injury severity. Non-fatal injury risks were not found to be increased in obese female drivers. The association between obesity and risk of non-fatal injury was much stronger for male drivers than for female drivers. The higher risk of non-fatal MVC injuries in obese male drivers might result from their different body shape and fat distribution compared with obese female drivers. Our findings should be considered for obesity reduction, traffic safety evaluation and vehicle design for obese male drivers and provide testable hypotheses for future studies.

    The prevalence of obesity is rising globally and in India. Overweight, obesity and related diseases need to be delineated in Asian Indian women. A literature search was done using key words like 'obesity', 'Asian Indian women', 'body fat distribution', 'type 2 diabetes', 'fertility', 'polycystic ovarian disease', metabolic syndrome', 'cardiovascular disease', 'non-alcoholic fatty liver disease', 'gender', 'sex' and 'prevalence' up to September 2012 in Pubmed and Google Scholar search engines. This review highlights the Asian Indian body composition with regards to obesity and provides a collated perspective of gender-specific prevalence of the co-morbidities. Recent data show that women (range of prevalence of overweight and obesity from different studies 15-61%) have higher prevalence of overweight and obesity as compared with men (range of prevalence of overweight and obesity from different studies 12-54%) in India and that obesity is increasing in the youth. The prevalence of overweight and obesity in both men and women steeply rose in a Punjabi community from Jaipur. Importantly, prevalence of abdominal obesity has been consistently higher in women than in men. The lowest prevalence (6.0%) of type 2 diabetes mellitus in women is reported from South India (rural Andhra Pradesh; 2006) and the highest (14.0%) by the National Urban Diabetes Survey (2001). Although the clustering of cardiovascular disease risk factors was generally high, it increased further in post-menopausal women. There are a number of factors that predispose Indian women to obesity; sedentary behaviour, imbalanced diets, sequential and additive postpartum weight gain and further decrease in physical activity during this period and cultural issues. In view of these data, preventive measures should be specifically targeted to Indian women.

    AIMS: Schizophrenia is associated with cardiovascular co-morbidity and a reduced life-expectancy of up to 20 years. Antipsychotics are dopamine D2 receptor antagonists and the standard of medical care in schizophrenia, but the drugs are associated with severe metabolic side effects like obesity...... and diabetes. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are registered for treatment of both obesity and type 2 diabetes. We investigated metabolic effects of the GLP-1RA, exenatide once-weekly, in non-diabetic, antipsychotic-treated, obese patients with schizophrenia. MATERIAL AND METHODS......: Antipsychotic-treated, obese, non-diabetic, schizophrenia spectrum patients were randomized to double-blinded adjunctive treatment with once-weekly subcutaneous exenatide (n = 23) or placebo (n = 22) injections for three months. The primary outcome was body weight loss after treatment and repeated measures...

    Objective: To determine the effect of visfatin on blood lipid levels in balb/c strain of albino mice. Design: Quasi experimental study. Place and duration of study: The study was carried out at the department of Physiology, Army Medical College, Rawalpindi and National Institute of Health Sciences, Islamabad from April to December 2007. Material and Methods: One hundred and twenty balb/c strain albino mice were procured from NIH, Islamabad. After taking base line blood samples, mice were divided randomly into four groups. Animals in groups I and II were made obese by feeding high fat / high carbohydrate diet whereas mice in Groups III and IV were induced diabetes mellitus by injecting streptozotocin. Groups I (obese) and III (diabetic) served as controls whereas groups II (obese treated) and IV (diabetic treated) were administered visfatin injection. Terminal intracardiac blood sample was used to measure the serum lipid and visfatin levels. Results: Serum lipid levels were found increased in obese and diabetic groups as compared to healthy mice. The administration of recombinant-histidine soluble (mice) visfatin significantly (p< 0.01) decreased the serum lipid levels with concomitant increase in HDL levels (p< 0.01) in obese and diabetic groups of mice and were comparable with baseline normal values of healthy controls. Conclusion: Visfatin is a potential antilipidemic adipocytokine that probably modulates insulin sensitivity and decreases atherogenic lipids (triglycerides, cholesterol, LDL and VLDL) with concomitant increase in HDL in obesity and diabetes mellitus.

    Pediatric obesity is a major public health threat. Obese children and adolescents are at increased risk for many medical and surgical conditions. These conditions may affect their quality of life and life expectancy. The rapidly progressive nature of type 2 diabetes mellitus within the first 5 years of obesity diagnosis is particularly concerning. Because health risk increases with degree of obesity, adolescents who may be eligible for more aggressive obesity treatment should be identified and counseled. Published by Elsevier Inc.

    Full Text Available BACKGROUND: Fibroblast growth factor-21 (FGF21 is known as an important endocrine and paracrine regulator of metabolic homeostasis. Recent studies have shown that FGF21 attenuates lipolysis in human adipocytes, which is suggested as a FGF21's mechanism as anti-hyperlipidemia, anti-hyperglycemia and anti-obesity. The aim of this study was to measure the correlation between FGF21, FFA, hsCRP and HOMA-IR among Indonesian obese non diabetic males. METHODS: The study was observational with cross sectional design. The analysis was done in 137 subjects aged 30-60 years with non diabetic abdominal obesity. We measured the biochemical markers FGF21, FFA, hsCRP, fasting insulin and fasting glucose. We also measured weight, height, waist circumrefence (WC, creatinine, serum glutamin oxaloacetic transaminase (SGOT, and serum glutamic pyruvic transaminase (SGPT, systolic blood pressure (SBP and diastolic blood pressure (DBP. Correlation between markers was measured using Pearson and Spearman's analysis. RESULTS: There were significant positive correlations between FGF21-HOMA-IR (r=0.314, p=0.000; FGF21-WC (r=0.173, p=0.043; FFA=hsCRP r=0.270, p=0.001; and WC-HOMA-IR (r=0.279, p=0.001. There was significant negative correlation between FGF21-FFA (r=-0.038, p=0.657 and FGF21-hsCRP (r=-0.061, p=0.482. CONCLUSIONS: In this study we found that although there was no significant correlation, FGF21 might act as an anti-lipolytic and anti-inflammation agent among Indonesian obese non-diabetic males. Our findings agree with results of previous studies that the positive correlation between FGF21-WC and FGF21-HOMA-IR might occur as a compensatory mechanism or resistance to FGF21 in obesity. KEYWORDS: obesity, FGF21, FFA, hsCRP, HOMA-IR.

    Full Text Available Consumption of non- or low-fat dairy products is recommended as a strategy to lower the risk of childhood obesity. However, recent evidence suggests that consumption of whole fat dairy products may, in fact, be protective against obesity. Our objective was to determine the association between milk fat consumption and severe obesity among three-year-old Latino children, a population with a disproportionate burden of obesity and severe obesity. 24-hour-dietary recalls were conducted to determine child intake in San Francisco based cohort recruited in 2006–7. Mother-child dyads were weighed and measured. The 24-hour recall data was analyzed to determine participants' consumption of whole milk, 2% milk, and 1% milk. The milk consumption data was used to calculate grams of milk fat consumed. The cross-sectional association between milk fat intake and severe obesity (BMI ≥ 99th percentile was determined using multivariable logistic regression. Data were available for 145 children, of whom 17% were severely obese. Severely obese children had a lower mean intake of milk fat (5.3 g vs. 8.9 g and fewer drank any milk (79% versus 95% for not severely obese children (p < 0.01. Among the potential confounders assessed, maternal BMI and maternal marital status were associated with severe obesity and were included in a multivariate model. In the multivariate model, higher milk fat consumption was associated with lower odds of severe obesity (OR 0.88 CI 0.80–0.97. Higher milk fat consumption is associated with lower odds of severe obesity among Latino preschoolers. These results call into question recommendations that promote consumption of lower fat milk.

AIMS: To determine the prevalence of risk for OSAS with or without daytime sleepiness in non-morbidly obese patients with NAFLD and evaluate the association with the severity of liver damage. METHODS: We considered 159 consecutive patients with histological NAFLD and body mass index (BMI 1; 9/13, 69% vs. 39/146, 27%; p = 0.003. At multivariate logistic regression analysis, OSAS with sleepiness was strongly associated with NASH and fibrosis>1 independently of known clinical risk factors such as age, gender, BMI, diabetes, and ALT levels (OR 7.1, 95% c.i. 1.7-51, p = 0.005 and OR 14.0, 95% c.i. 3.5-70, p = 0.0002, respectively. CONCLUSIONS: A proportion of NAFLD patients without severe obesity is at risk for OSAS with daytime sleepiness, which is associated with the severity of liver damage independently of body mass and other cofactors.

    The association between diabetes and cancer was hypothesized almost one century ago. Today, a vast number of epidemiological studies support that obese and diabetic populations are more likely to experience tissue-specific cancers, but the underlying molecular mechanisms remain unknown. Obesity, diabetes, and cancer share many hormonal, immune, and metabolic changes that may account for the relationship between diabetes and cancer. In addition, antidiabetic treatments may have an impact on the occurrence and course of some cancers. Moreover, some anticancer treatments may induce diabetes. These observations aroused a great controversy because of the ethical implications and the associated commercial interests. We report an epidemiological update from a mechanistic perspective that suggests the existence of many common and differential individual mechanisms linking obesity and type 1 and 2 diabetes mellitus to certain cancers. The challenge today is to identify the molecular links responsible for this association. Classification of cancers by their molecular signatures may facilitate future mechanistic and epidemiological studies. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U.

    2014-01-01

    Aims: The present study was designed to assess some pharmacological effects of cinnamon (CAE) and ginger (GAE) aqueous extracts in obese diabetic rats, and to elucidate the potential mechanisms. Materials and Methods: Forty-two Sprague-Dawley rats were randomized into 6 equal groups. Group 1 was a negative control and the other groups were rendered obese by feeding rats on high-fat diet for 4 weeks. The obese rats were subcutaneously injected with alloxan for 5*days to induce diabetes. Group 2 was a positive control, and Groups 3, 4, 5 and 6 were orally given CAE in doses 200 and 400 mg/kg and GAE in the same doses, respectively for 6 weeks. Blood samples were collected for serum biochemical analyses. Kidneys were dissected out to assay activity of tissue antioxidant enzymes: Superoxide dismutase, glutathione peroxidase and catalase. Results: CAE and GAE significantly reduced body weight and body fat mass; normalized serum levels of liver enzymes; improved lipid profile; decreased blood glucose and leptin and increased insulin serum levels in obese diabetic rats. Both extracts also increased activity of kidney antioxidant enzymes. Conclusion: CAE and GAE exhibit anti-obesity, hepatoprotective, hypolipidemic, antidiabetic and anti-oxidant effects in obese diabetic rats. These results confirm the previous reports on both extracts. The potential mechanisms underlying these effects are fully discussed and clarified. Our results affirm the traditional use of cinnamon and ginger for treating patients suffering from obesity and diabetes. The obese diabetic rat model used in this study is a novel animal model used in pharmacology researches. PMID:26401364

    Our aim was to examine the secular trends in obesity prevalence among Spanish adults with diabetes. Data were collected from 8 waves (from 1987 to 2012) of the National Health Surveys (NHS). NHS are cross-sectional studies conducted in representative samples of the Spanish adult population. Data of 7378 adults (≥16 years) who reported having been diagnosed of diabetes were analyzed. Previously validated self-reported weight and height were used to estimate body mass index (BMI). Obesity was defined as a BMI of 30kg/m 2 or greater. Age-adjusted obesity prevalence for each wave was calculated by the direct standardization method. From 1987 to 2012 age-adjusted prevalence of obesity among persons with diabetes increased from 18.2% (95% confidence interval [CI]: 14.2-22.2%) to 39.8% (95% CI: 36.8-42.8%). Age-adjusted prevalence of obesity in males with diabetes increased from 13.2% (95% CI: 7.3-19.1%) to 38.0% (95% CI: 33.8-42.1%) and in females from 23.0% (95% CI: 17.6-28.4%) to 42.3% (95% CI: 38.0-46.6%). Between 1987 and 2012 the prevalence of obesity markedly increased in Spain among adults with diabetes. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

    : Obesity is a key factor for cardiovascular diseases and complications. Obesity is associated with hypertension, dyslipidemia and type II diabetes, which are the major predictors of cardiovascular disease in the future. It predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke that are the main causes of cardiovascular hospitalization and mortality. As obesity and the cardiovascular effects on the vessels and the heart start early in life, even from childhood, it is important for health policies to prevent obesity very early before the disease manifestation emerge. Key roles in the prevention are strategies to increase physical exercise, reduce body weight and to prevent or treat hypertension, lipids disorders and diabetes earlier and efficiently to prevent cardiovascular complications.Epidemiology and mechanisms of obesity-induced hypertension, diabetes and dyslipidemia will be reviewed and the role of lifestyle modification and treatment strategies in obesity will be updated and analyzed. The best treatment options for people with obesity, hypertension, diabetes and dyslipidemia will discussed.

    Full Text Available Despite extensive genetic and immunological research, the complex etiology and pathogenesis of type I diabetes remains unresolved. During the last few years, our attention has been focused on factors such as abnormalities of islet function and/or microenvironment, that could interact with immune partners in the spontaneous model of the disease, the non-obese diabetic (NOD mouse. Intriguingly, the first anomalies that we noted in NOD mice, compared to control strains, are already present at birth and consist of 1 higher numbers of paradoxically hyperactive ß cells, assessed by in situ preproinsulin II expression; 2 high percentages of immature islets, representing islet neogenesis related to neonatal ß-cell hyperactivity and suggestive of in utero ß-cell stimulation; 3 elevated levels of some types of antigen-presenting cells and FasL+ cells, and 4 abnormalities of extracellular matrix (ECM protein expression. However, the colocalization in all control mouse strains studied of fibroblast-like cells (anti-TR-7 labeling, some ECM proteins (particularly, fibronectin and collagen I, antigen-presenting cells and a few FasL+ cells at the periphery of islets undergoing neogenesis suggests that remodeling phenomena that normally take place during postnatal pancreas development could be disturbed in NOD mice. These data show that from birth onwards there is an intricate relationship between endocrine and immune events in the NOD mouse. They also suggest that tissue-specific autoimmune reactions could arise from developmental phenomena taking place during fetal life in which ECM-immune cell interaction(s may play a key role.

    To determine diabetes incidence over time among obese young adults without metabolic risk factors. Incident diabetes during a median follow-up of 6.1 years was assessed among 33,939 young men (mean age 30.9 ± 5.2 years) of the Metabolic, Lifestyle and Nutrition Assessment in Young Adults cohort who were stratified for BMI and the number of metabolic abnormalities (based on the Adult Treatment Panel-III). Metabolically healthy (MH) obesity was defined as BMI ≥30 kg/m2 in the presence of normoglycemia, normal blood pressure, and normal levels of fasting triglyceride and HDL-cholesterol levels (n = 631). A total of 734 new cases of diabetes were diagnosed during 210,282 person-years of follow-up. The incidence rate of diabetes among participants with no metabolic risk factors was 1.15, 2.10, and 4.34 cases per 1,000 person-years among lean, overweight, and obese participants, respectively. In a multivariable model adjusted for age, region of origin, family history of diabetes, physical activity, fasting plasma glucose, triglyceride level, HDL-cholesterol, systolic blood pressure, and white blood cell count, a higher diabetes risk was observed among MH-overweight (hazard ratio [HR] 1.89 [95% CI 1.25-2.86]; P young adults from incident diabetes associated with overweight and obesity. © 2014 by the American Diabetes Association.

    2015-01-01

    Obesity and type 2 diabetes are metabolic diseases that have reached epidemic proportions worldwide. Although their etiology is complex, both result from interplay between behaviour, environment and genetic factors. Within ambient determinants, human overall gut bacteria have been identified as a crucial mediator of obesity and its consequences. Gut microbiota plays a crucial role in gastro-intestinal mucosa permeability and regulates the fermentation and absorption of dietary polyssacharides, which may explain its importance in the regulation of fat accumulation and the resultant development of obesity-related diseases. The main objective of this review is to address the pathogenic association between gut microbiota and obesity and to explore related innovative therapeutic targets. New insights into the role of the small bowel and gut microbiota in diabetes and obesity may make possible the development of integrated strategies to prevent and treat these metabolic disorders.

    As the available therapies for diabetes and obesity are not effective enough, diabetologists and educators search for new methods to collaborate with patients in order to support their health behaviors. The aim of this review is to discuss perspectives for the development of new empowerment-type therapies in the treatment of diabetes/obesity. Empowerment is a process whereby patients gain the necessary knowledge to influence their own behavior to improve the quality of their lives. It is carried out in five stages: (1) identify the problem, (2) explain the feelings and meanings, (3) build a plan, (4) act, and (5) experience and assess the execution. Although many years have passed since the advent and popularization of the concept of empowerment, the area remains controversial, mainly with regard to the methodology of therapy. Some previous studies have confirmed the positive effect of empowerment on body weight, metabolic control, and quality of life of patients with type 2 diabetes; however, few studies have been conducted in patients with type 1 diabetes. There is still a need to confirm the effectiveness of empowerment in accordance with Evidence Based Medicine by performing long-term observational studies in a large group of patients. In future, empowerment may become part of the standard of care for patients with diabetes and/or obesity.

    To investigate the association between overweight and obesity (in terms of BMI) and diabetes, HBP and diabetes-HBP comorbidity among adult women non-pregnant in Bangladesh. Information about demographics, socioeconomic, blood pressure and blood glucose levels were collected for 2022 women ageing above 35 years were collected from Bangladesh Demographic and Health Survey (BDHS 2011). The primary outcome variables were diabetes and high blood pressure. Diabetes was defined as fasting plasma glucose value ≥7.0mmol/L and HBP as systolic blood pressure ≥140mmHg or diastolic blood pressure ≥90mmHg. Blood pressure and plasma glucose measurement were performed by standard clinical procedures. Data were analysed using cross-tabulation, chi-square tests and logistic regression methods. Mean age of the participants was 41.42 (SD=4.37). 38.7% of the women had BMI values ≥25. The prevalence of HBP, diabetes, and diabetes-HBP comorbidity was respectively 18% and 5.1%, and 2%. The adjusted odds of having diabetes, HBP and Diabetes-HBP comorbidity were respectively 2.14 (p=0.002; 95%CI=1.31-3.48), 2.3 (p=<0.0001; 95%CI=1.70-2.98), and 3.4 (p=0.004; 95%CI=1.47-7.81) times higher among overweight/obese women compared to those with normal weight. Overweight and obesity account for a major proportion of diabetes, HBP and the comorbidity of these two among non-pregnant women. There remains a considerable risk for future expansion of diabetes and HBP as the prevalence of overweight/obesity is rising constantly. Maintaining a healthy BMI needs to be regarded as among the most important diabetes and HBP preventive strategies among Bangladeshi women. Copyright © 2016 Diabetes India. Published by Elsevier Ltd.

    Full Text Available Background Children with severe obesity are more likely to develop diabetes and cardiovascular diseases at a younger age. Inflammation and oxidative stress associated with childhood obesity may be important in the development of insulin resistance and atherosclerosis. Objective To compare levels of high-sensitivity C-reactive protein (hsCRP and malondialdehyde (MDA by the severity of obesity in prepubertal children aged 6 to 10 years. Methods We conducted a cross-sectional study at the Pediatric Nutrition and Metabolic Syndrome Clinic, Sanglah Hospital, Bali, from August to December 2015. Subjects were categorized into three body mass index (BMI groups, according to the 2000 Centers for Disease Control and Prevention growth chart: overweight (85th-94.9th percentile, obese (95th-98.9th percentile, or severely obese (≥ 99th percentile. Plasma MDA and serum hsCRP were analyzed in blood specimens obtained at enrollment. Data were analyzed by Kruskal-Wallis test, followed by Mann-Whitney U test for post-hoc comparison between groups. Results Subjects were 20 overweight children, 29 obese children, and 28 severely obese children. Levels of MDA were significantly higher in the severely obese [median 0.25 (IQR 0.1 μmol/L] than in obese subjects [median 0.19 (IQR 0.1 μmol/L; P=0.001], and than in overweight subjects [median 0.16 (IQR 0.1 μmol/L; P<0.0001]. Also, the severely obese children had significantly higher hsCRP levels compared to obese [median 3.2 (IQR 2.0 mg/L vs. 1.3 (1.6 mg/L, respectively; P<0.0001] and compared to overweight children [median 0.7 (IQR 0.6 mg/L; P<0.0001].     Conclusion Prepubertal children at the ≥ 99th percentile for BMI (severely obese are more likely to have significantly higher hsCRP and MDA compared to those in the obese and overweight groups.

    Obesity and diabetes are the most prevailing health concerns worldwide and their incidence is increasing at a high rate, resulting in enormous social costs. Obesity is a complex disease commonly accompanied by insulin resistance and increases in oxidative stress and inflammatory marker expression, leading to augmented fat mass in the body. Diabetes mellitus (DM) is a metabolic disorder characterized by the destruction of pancreatic β cells or diminished insulin secretion and action insulin. Obesity causes the development of metabolic disorders such as DM, hypertension, cardiovascular diseases, and inflammation-based pathologies. Flavonoids are the secondary metabolites of plants and have 15-carbon skeleton structures containing two phenyl rings and a heterocyclic ring. More than 5000 naturally occurring flavonoids have been reported from various plants and have been found to possess many beneficial effects with advantages over chemical treatments. A number of studies have demonstrated the potential health benefits of natural flavonoids in treating obesity and DM, and show increased bioavailability and action on multiple molecular targets. This review summarizes the current progress in our understanding of the anti-obesity and anti-diabetic potential of natural flavonoids and their molecular mechanisms for preventing and/or treating obesity and diabetes.

    Full Text Available Abstract Background Fucoxanthin is a xanthophyll present in brown seaweeds and has several beneficial effects, including anti-obesity and anti-diabetic effects. However, we and another group previously observed that fucoxanthin increases serum cholesterol levels in rodents. Cholesterol is an important component of cell membranes and biosynthesis of bile acids. Serum cholesterol levels are also closely associated with atherosclerosis. Therefore, we sought to identify the mechanism underlying the increase in serum cholesterol levels by fucoxanthin. Methods Diabetic/obese KK-Ay mice were fed a diet containing 0.2% fucoxanthin for 4 weeks. The mice were sacrificed, and total blood samples were collected for the measurement of serum total cholesterol, HDL-cholesterol and non-HDL-cholesterol levels. Cholesterol content in tissues was also analyzed. Real-time PCR and Western blotting were performed to determine hepatic mRNA and protein expression of genes involved in cholesterol metabolism, respectively. Results Dietary fucoxanthin significantly increased serum HDL and non-HDL cholesterol levels, and reduced hepatic cholesterol content. In liver, the expression of SREBP1, SREBP2 and their target genes involved in cholesterol biosynthesis significantly increased and tended to increase in the fucoxanthin-fed mice, respectively. In contrast, hepatic levels of LDLR and SR-B1 proteins which is important factors for LDL-cholesterol and HDL-cholesterol uptake in the liver from serum, decreased to 60% and 80% in the fucoxanthin-fed mice, respectively, compared with the control mice. Further, we found that dietary fucoxanthin significantly increased the mRNA expression of proprotein convertase subtilisin/kexin type 9 (PCSK9, which enhances intracellular degradation of LDLR in lysosomes. Conclusions Fucoxanthin increased HDL-cholesterol and non-HDL-cholesterol levels in KK-Ay mice by inducing SREBP expression and reduced cholesterol uptake in the liver via

    OBJECTIVE It is unknown whether any association between neighborhood food environment and obesity varies according to individual income and/or race/ethnicity. The objectives of this study were to test whether there was an association between food environments and obesity among adults with diabetes and whether this relationship differed according to individual income or race/ethnicity. RESEARCH DESIGN AND METHODS Subjects (n = 16,057) were participants in the Diabetes Study of Northern California survey. Kernel density estimation was used to create a food environment score for each individual’s residence address that reflected the mix of healthful and unhealthful food vendors nearby. Logistic regression models estimated the association between the modeled food environment and obesity, controlling for confounders, and testing for interactions between food environment and race/ethnicity and income. RESULTS The authors found that more healthful food environments were associated with lower obesity in the highest income groups (incomes 301–600% and >600% of U.S. poverty line) among whites, Latinos, and Asians. The association was negative, but smaller and not statistically significant, among high-income blacks. On the contrary, a more healthful food environment was associated with higher obesity among participants in the lowest-income group (food environments may have different health implications when financial resources are severely constrained.

    In murine models of obesity/diabetes, there is an increase in plasma serum amyloid A (SAA) levels along with redistribution of SAA from high-density lipoprotein (HDL) to apolipoprotein B (apoB)-containing lipoprotein particles, namely, low-density lipoprotein and very low-density lipoprotein. The goal of this study was to determine if obesity is associated with similar SAA lipoprotein redistribution in humans. Three groups of obese individuals were recruited from a weight loss clinic: healthy obese (n = 14), metabolic syndrome (MetS) obese (n = 8), and obese with type 2 diabetes (n = 6). Plasma was separated into lipoprotein fractions by fast protein liquid chromatography, and SAA was measured in lipid fractions using enzyme-linked immunosorbent assay and Western blotting. Only the obese diabetic group had SAA detectable in apoB-containing lipoproteins, and SAA reverted back to HDL with active weight loss. In human subjects, SAA is found in apoB-containing lipoprotein particles only in obese subjects with type 2 diabetes, but not in healthy obese or obese subjects with MetS.

    Background: Diabetes mellitus (DM) is a metabolic disorder characterised by chronic hyperglycaemia with disturbances in carbohydrate, fat and protein metabolism arising from defect in insulin secretion or action or both. The clinical guidelines recommend measurement of BMI as vital signs for evaluating the obese and diabetic patients. Methods: This study was carried out on 160 diabetics, which were divided on the basis of BMI into obese (120) and non-obese (40) diabetics from Peshawar district. All patients had their triglycerides and glucose checked after over night fast. Results: The serum triglyceride in diabetics having BMI >30 (obese) was increased as compared to patients having BMI <30 (non-obese). The comparison of serum glucose level in obese diabetics was found to be significantly raised as compared to non-obese diabetics. Conclusions and Recommendations: It was concluded that dyslipidemia is common in all diabetics. The abnormal triglyceride level can improve with good glycemic control, but do not reach the normal state. Good glycaemic control, Reducing BMI, periodic checkups of lipids and blood glucose are recommended for all diabetics in order to avoid complications. (author)

Causes for exclusion will be publications that studied patients diagnosed with diabetes mellitus type 1; articles that focused on the treatment and complications of diabetes mellitus type 2; publications that have studied other clinical or psychiatric conditions (for instance, seizure disorder or history of schizophrenia, bipolar disorder, psychotic symptoms or dementia. Conclusion: The results of this study will form the basis for a better understanding of the association between obesity and depression in patients with diabetes mellitus type 2, and will allow development of prediction tools and better interventions. It is evident that several modifiable and non-modifiable risk factors play an important role in the pathogenesis of diabetes among population

    Objective: To study the changes of serum leptin in patients with simple obesity and patients with type 2 diabetes mellitus complicated with obesity in order to explore the relationship of leptin and insulin resistance and the role of leptin in the occurrence of type 2 diabetes mellitus. Methods: 60 cases of simple obesity, 60 cases of type 2 diabetes mellitus and 30 cases of normal control were included according to the diagnostic criteria of obesity and type 2 diabetes mellitus. the levels of fasting serum leptin, fasting serum insulin, fasting glucose, fasting blood lipid were measured in all cases. The body mass index (BMI) and insulin action index were calculated. Results: The level of BMI, serum leptin, serum insulin, blood lipid were significantly higher in patients with simple obesity and with type 2 diabetes mellitus complicated with obesity than in normal control cases, while (IAI) was significantly lower. The levels of free serum leptin, serum insulin, free glucose, and blood lipid were significantly higher in patients with type 2 diabetes mellitus complicated with obesity than in patients with simple obesity, while IAI was significantly lower. The level of serum leptin was positively correlated with BMI (r=0.48, P<0.55) and fasting serum leptin (r=0.55, P<0.05) and negatively correlated with IAI (r=-0.47, P<0.05) in patients with type 2 diabetes complicated with obesity. Conclusion: The overexpression of serum leptin may play an important role in the occurrence of the insulin resistance and type 2 diabetes mellitus in obesity patients. (authors)

    This study examined adherence to a personalized, community-based exercise intervention by sedentary adolescents with type 1 or type 2 diabetes or those with obesity. We conducted a pretest-posttest investigation to explore the application of an individualized exercise prescription based upon current fitness level for 39 adolescents (20 with type 1 diabetes, 9 with type 2 diabetes, and 10 obese) over 16 weeks in community settings. Subjects were recruited from a university-based pediatric endocrinology clinic in the southwestern United States. Adherence to the exercise prescription was monitored using accelerometers over the entire intervention period. Moderate-to-vigorous physical activity (MVPA) levels significantly increased over sedentary baseline values (p exercise is challenging. Personalized approaches that include adolescent choices with family support and ongoing motivation can improve individual exercise adherence and a sense of personal health.

    Obesity, metabolic syndrome, and diabetes mellitus are increasing in epidemic proportions globally. Prameha is a syndrome described in the ancient Ayurvedic texts that includes clinical conditions involved in obesity, prediabetes, diabetes mellitus, and metabolic syndrome. Integrating the theory and modalities of Ayurveda in the management of these disorders may prove to be beneficial. Even though Prameha is a Tridoshaja Vyadhi (a disease involving all three of the psychophysiologic principles known as Doshas [i.e., Vata, Pitta, and Kapha]), it is basically a disease with Kapha predominance. There are 20 subtypes of Prameha due to the interaction of the three Doshas and 10 Dushyas (disturbed functioning of the principles that support the various bodily tissues); several of these subtypes have sweet urine, whereas some of them have different coloration of the urine, highlighting the inflammatory conditions involved in the metabolic syndrome. This disease has close ties to Sthaulya (i.e., obesity). With regard to diabetes mellitus, Sahaja Prameha and Jatah Pramehi correlate with type 1 diabetes; Apathyanimittaja Prameha correlates with type 2 diabetes. Madhumeha is a subtype of Vataja Prameha (Prameha with Vata predominance) that can occur as the terminal stage of type 2 diabetes (in which insulin is required), or as type 1 diabetes beginning in early childhood. The latter is defined as Jatah Pramehi Madhumehino in Charaka Samhita, one of the classical Ayurvedic texts. Various dietary, lifestyle, and psychologic factors are involved in the etiology of Prameha, particularly in relation to disturbances in fat and carbohydrate metabolism. The ancient Ayurvedic knowledge regarding Prameha can be utilized to expand the current understanding of obesity, metabolic syndrome, and diabetes.

    To identify factors underpinning the gap in diabetes rates between Aboriginal and non-Aboriginal people in non-remote NSW. This will indicate appropriate target areas for policy and for monitoring progress towards reducing the gap. Data from the 2004-05 National Health Survey and National Aboriginal and Torres Strait Islander Health Survey were used to estimate differences in self-reported diabetes rates and risk/prevention factors between Aboriginal and non-Aboriginal people in non-remote NSW. Logistic regression models were used to investigate the contribution of each factor to predicting the probability of diabetes. Risk factors for diabetes are more prevalent and diabetes rates 2.5 to 4 times higher in Aboriginal compared to non-Aboriginal adults in non-remote NSW. The odds of (known) diabetes for both groups are significantly higher for older people, those with low levels of education and those who are overweight or obese. In the Aboriginal sample, the odds of diabetes are significantly higher for people reporting forced removal of their relatives. Differences in BMI and education appear to be driving the diabetes gap, together with onset at younger ages in the Aboriginal population. Psychological distress, indicated by removal of relatives, may contribute to increased risk of diabetes in the Aboriginal population. The results imply that improved nutrition and exercise, capacity to access and act upon health care information and early intervention are required to reduce the diabetes gap. Current strategies appear to be appropriately aligned with the evidence; however, further research is required to determine whether implementation methods are effective. © 2014 Public Health Association of Australia.

    Full Text Available Amy Fleischman, Erinn T RhodesDivision of Endocrinology, Children’s Hospital Boston, Boston, MA, United StatesAbstract: Childhood obesity has become a national and international epidemic. The prevalence and incidence of type 2 diabetes in youth have been increasing, and type 2 diabetes is one of the most challenging complications of obesity in childhood. Comprehensive lifestyle interventions that include attention to dietary change, increased physical activity and behavior change appear to be required for the successful treatment of pediatric obesity. In particular, aspects of behavioral interventions that have been identified as contributing to effectiveness have included intensity, parent/family participation, addressing healthy dietary change, promoting physical activity, and involving behavioral management principles such as goal setting. A multidisciplinary team approach is required for successful management of type 2 diabetes in youth as well. As with many therapies in pediatrics, clinical trials and support for treatments of obesity and type 2 diabetes in youth lag behind adult data. Pediatric recommendations may be extrapolated from adult data and are often based on consensus guidelines. Type 2 diabetes in children is most commonly managed with lifestyle modification and medications, metformin and/or insulin, the only medications currently approved for use in children. However, many opportunities exist for ongoing research to clarify optimal management for obesity and type 2 diabetes in youth.Keywords: children, obesity, type 2 diabetes, metformin, insulin, bariatric surgery

  7. Molecular Mechanisms of the Anti-Obesity and Anti-Diabetic Properties of Flavonoids

    Full Text Available Obesity and diabetes are the most prevailing health concerns worldwide and their incidence is increasing at a high rate, resulting in enormous social costs. Obesity is a complex disease commonly accompanied by insulin resistance and increases in oxidative stress and inflammatory marker expression, leading to augmented fat mass in the body. Diabetes mellitus (DM is a metabolic disorder characterized by the destruction of pancreatic β cells or diminished insulin secretion and action insulin. Obesity causes the development of metabolic disorders such as DM, hypertension, cardiovascular diseases, and inflammation-based pathologies. Flavonoids are the secondary metabolites of plants and have 15-carbon skeleton structures containing two phenyl rings and a heterocyclic ring. More than 5000 naturally occurring flavonoids have been reported from various plants and have been found to possess many beneficial effects with advantages over chemical treatments. A number of studies have demonstrated the potential health benefits of natural flavonoids in treating obesity and DM, and show increased bioavailability and action on multiple molecular targets. This review summarizes the current progress in our understanding of the anti-obesity and anti-diabetic potential of natural flavonoids and their molecular mechanisms for preventing and/or treating obesity and diabetes.

    Oxidative stress occurs whenever the release of reactive oxygen species (ROS) exceeds endogenous antioxidant capacity. In this paper, we review the specific role of several cardiovascular risk factors in promoting oxidative stress: diabetes, obesity, smoking, and excessive pollution. Specifically, the risk of developing heart failure is higher in patients with diabetes or obesity, even with optimal medical treatment, and the increased release of ROS from cardiac mitochondria and other sources likely contributes to the development of cardiac dysfunction in this setting. Here, we explore the role of different ROS sources arising in obesity and diabetes, and the effect of excessive ROS production on the development of cardiac lipotoxicity. In parallel, contaminants in the air that we breathe pose a significant threat to human health. This paper provides an overview of cigarette smoke and urban air pollution, considering how their composition and biological effects have detrimental effects on cardiovascular health.

    Gestational diabetes mellitus is believed to be a risk factor for childhood overweight/obesity. We aimed to assess whether this association is either a reflection or independent of confounding by maternal BMI. Data from 7355 mother-child dyads of the German Perinatal Prevention of Obesity cohort with full anthropometric information on mothers and children, gestational diabetes and confounding factors were obtained at school entry health examination. We calculated crude and adjusted logistic regression models for the association of gestational diabetes and childhood overweight/obesity and abdominal adiposity defined by age- and sex-specific percentiles for BMI and waist circumference. Among all children (mean age 5.8 years), 8.1% were overweight, 2.6% were obese and 15.5% had abdominal adiposity. The prevalence of overweight (obesity) was 21% (8.2%) in children of mothers with gestational diabetes and 10.4% (2.4%) in children of healthy mothers. Analyses with adjustment for maternal BMI and other potential confounders yielded an odds ratio of 1.81 (95% CI 1.23-2.65) and 2.80 (95% CI 1.58-4.99) for the impact of gestational diabetes on childhood overweight and obesity, respectively. Similar results were obtained for the risk of childhood abdominal adiposity (odds ratio 1.64, 95% CI 1.16-2.33) by maternal gestational diabetes. The postulated increased risk of overweight and abdominal adiposity in offspring of mothers with gestational diabetes cannot be explained by maternal BMI alone and may be stronger for childhood obesity than for overweight. © 2013 The Authors.

    Full Text Available The occurrence of liver disease and raised liver enzymes is common in diabetic patients and the increasing level of enzymes indicates the severity of hepatic injury. Very few studies have addressed this issue in Bangladesh though Bangladeshi population is very much susceptible to diabetes. This study investigated a total of 1400 diabetic patients and 100 non diabetic individuals to compare the level of liver enzymes between diabetic and non-diabetic subjects. The comparisons were made among subjects who were referred to the department of Gastro-hepato-pancreatic diseases (GHPD of BIRDEM with the clinical diagnosis of chronic hepatitis and other gastro-intestinal disorders. The investigations included alanine aminotransferase (ALT, aspartate aminotransferase (AST, alkaline phosphatase (ALP and bilirubin levels. The subjects were categorized with and without hepatitis based on these investigations. The biochemical markers (ALT, AST, ALP, bilirubin did not differ significantly between non-diabetic male and female subjects. Neither the differences were significant between diabetic males and females though the diabetic patients had higher level of markers. In contrast, when compared between diabetic and non-diabetic subjects there were striking differences in either sex. Compared with the non-diabetic the diabetic subjects had significantly higher level of ALT (48.3 vs. 277.0, AST (42.0 vs. 213.0 and ALP (148 vs. 302 in males (p<0.005 for all. Similarly, these values were found significantly higher in diabetic females than their non-diabetic counterparts (p<0.01. For bilirubin, it was also found significant in males (p<0.001. The study revealed that the liver enzymes were found elevated in both diabetic and non-diabetic subjects who were referred with clinically diagnosed hepatitis. The enzymes were found markedly elevated among the diabetic than non diabetic patients, which indicate hepatic injury was more marked among the diabetic patients. Further

    Bariatric procedures provide an effective means of short term weight loss and sustained weight control for the morbidly obese. The effect of bariatric procedures on smoking habit in obese subjects is not well known. Therefore, we examined the short term effect of bariatric surgery on smoking habit of severe obese patients up to 12 months from the intervention. Smoking habit was assessed in a cohort of 78 morbid smoking obese patients followed at our clinic for bariatric procedures. They underwent non surgical intra-gastric balloon (IB) or surgical procedures such as lap-band laparoscopic surgery (LAGB) or sleeve gastrectomy/gastric by-pass (SPG). Subjects were administered a written questionnaire about their smoking habit before and 3, 6 and 12 months after the procedures. No differences were found among the three groups at 6 and 12 months after the procedures (IB 21 %, LAGB 6 %, SPG 5 %; and IB 14 %, LAGB 3 %, SPG 5 %). Only after 3 months, the rate of quitting of the IB group was higher than LAGB and SPG groups (36 %, 6 % and 5 %, respectively; p = 0.02). Bariatric procedures have no effects on smoking habit of moderate-to-heavy smoker severe obese patients. The use of other traditional smoking cessation methods in patients undergone to bariatric procedures should be implemented.

    Rates of extreme forms of obesity are rapidly rising, as is the use of bariatric surgery for its treatment. The aim of the present study was to examine selected behavioral factors associated with severity of obesity among preoperative bariatric surgery patients in the San Antonio area, focusing specifically on the effects of fast food consumption. We used ordered logistic regression to model behavioral and attitudinal effects on obesity outcomes among 270 patients. These outcomes were based on the severity of obesity and were measured on the basis of body mass index. Our results indicated that, among the behavioral factors, fast food consumption exerted the largest influence on higher levels of obesity. These remained after controlling for several social and demographic characteristics. Our findings suggest that higher rates of fast food consumption are connected to the increasing rates of severe obesity. Given that morbid and super morbid obesity rates are growing at a more advanced pace than moderate obesity, it is necessary to explore the behavioral characteristics associated with these trends.

    Full Text Available Objective: This study aimed to compare serum adiponectin, visfatin, and omentin between non-pregnant and pregnant women in overall, non-obese, and obese subjects. Methods: There were 40 pregnant and 33 non-pregnant women classified by body mass index (BMI into non-obese or obese subjects. Fasting blood samples were collected in the morning for the non-pregnant group and before delivery for the pregnant group. Results: Plasma glucose levels were significantly lower, but plasma insulin levels were significantly higher in pregnant when compared to non-pregnant women in overall, non-obese, and obese women (p<0.05 all. The homeostasis model assessment of insulin resistance (HOMA-IR was significantly higher, but the quantitative insulin sensitivity check index (QUICKI was significantly lower only in obese pregnant when compared to obese non-pregnant women (p<0.01 all. However, in non-obese women, HOMA-IR and QUICKI were comparable between pregnant and non-pregnant women. Serum adiponectin, visfatin, and omentin were significantly lower in pregnant compared to non-pregnant women in overall, non-obese, and obese groups (p<0.05 all. In pregnant women, serum adiponectin and omentin levels were significantly lower in obese compared to non-obese pregnant women while serum visfatin levels were comparable in both groups. Serum adiponectin levels were highest followed by omentin and visfatin, respectively in both non-obese and obese pregnant groups. These results indicated that lower serum adiponectin, visfatin, and omentin in pregnant women might contribute to higher insulin resistance in pregnancy. Furthermore, serum adiponectin and omentin were reduced in increasing adiposity similarly to non-pregnant women. Conclusion: Lower serum adiponectin, visfatin, and omentin in pregnant women might lead to decreased insulin sensitivity in these women.

    Obesity and being overweight is the most powerful risk factor accounting for 80-90% of patients with type 2 diabetes mellitus (T2DM). The epidemic of obesity is driving the diabetes epidemic to alarming levels and primary care is becoming an important setting for obesity management in T2DM in India. Yet many primary care providers feel ill-equipped or inadequately supported to address obesity in patients with diabetes. This article reviews the most recent and strongest evidence-based strategies that may aid physicians in management of obesity in patients with T2DM in primary care. A systematic literature search of MEDLINE using the search terms Obesity, Obesity in T2DM, weight loss and Primary Care was conducted. The American Diabetes Association, National Institute for Health, National Institute of Health and Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN) and World Health Organization websites were also searched. Most studies in this area are observational in design with few randomized controlled trials (RCTs). Articles and studies involving meta-analysis or RCTs were preferred over other types. Effective weight management treatment in T2DM patient can be implemented in the primary care setting. Evidence based individualized lifestyle and pharmacologic measures supported by behavioral intervention and counseling with appropriate and informed surgical referrals has the potential to improve the success of weight management within primary care.

    Full Text Available Anti-obesity effects of onion extract were determined in obesity and diabetes-prone Zucker diabetic fatty rats by measuring the efficacy of markers concerned with diabetes and obesity. Body and adipose tissue weights in 5% of onion extract-fed group were found to be significantly lower than the control group without onion extract. Fasting blood glucose and HOMA-IR levels were also improved, although the serum insulin and leptin levels did not show any remarkable difference. Serum triglyceride and free fatty acid levels in both the 3% and 5%-fed group were found to be reduced compared to the control group. Additionally the feeding of the onion extract increased the glucose tolerance. These results suggest that dietary onion extract is beneficial for improving diabetes by decreasing lipid levels. We also examined differentiation ability of rat white preadipocyte cells using the onion extract and its sulfur-containing components. Cycloalliin, S-methyl-l-cysteine, S-propyl-l-cysteine sulfoxide, dimethyl trisulfide, especially S-methyl-l-cysteine sulfoxide were reported to be effective in inhibiting formation of oil drop in the cells, suggesting that these compounds may be involved in the anti-obesity effect of the onion extract.

    Diabetes mellitus is a risk factor for severe dengue in adults, but few studies have examined the association between metformin use and disease severity in dengue. In addition to its effect on glucose control, metformin has been associated with pleiotropic properties in preclinical studies. Using a cohort of laboratory-confirmed adult (≥21 years) dengue patients with diabetes mellitus admitted to Tan Tock Seng Hospital, we conducted a retrospective cohort study involving 131 (58.7%) metformin users and 92 (41.3%) non-users. Dengue severity was categorized as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS) in World Health Organization (WHO) 1997 criteria and severe dengue (SD) in WHO 2009 criteria. Multivariable Poisson regression with robust error variance was used to estimate risk ratio (RR). Compared with non-use, metformin use was associated with a decreased risk of developing severe dengue (adjusted risk ratio [aRR] = 0.60, 95% confidence interval [CI]: 0.37-0.98, P = 0.04). Additionally, there was an inverse dose-response relationship (aRR = 0.69, 95% CI: 0.49-0.98, P = 0.04) with dengue severity as classified by WHO 2009 criteria. Use of metformin, however, was not associated with dengue severity based on WHO 1997 criteria; and no dose-response relationship was noted. Our results suggest metformin use could attenuate disease severity in dengue-infected diabetes mellitus individuals.

    The aim of this study is to determine the relationships of vitamin D with diabetes, insulin resistance obesity, and metabolic syndrome. Intra cellular vitamin D receptors and the 1-α hydroxylase enzyme are distributed ubiquitously in all tissues suggesting a multitude of functions of vitamin D. It plays an indirect but an important role in carbohydrate and lipid metabolism as reflected by its association with type 2 diabetes (T2D), metabolic syndrome, insulin secretion, insulin resistance, polycystic ovarian syndrome, and obesity. Peer-reviewed papers, related to the topic were extracted using key words, from PubMed, Medline, and other research databases. Correlations of vitamin D with diabetes, insulin resistance and metabolic syndrome were examined for this evidence-based review. In addition to the well-studied musculoskeletal effects, vitamin D decreases the insulin resistance, severity of T2D, prediabetes, metabolic syndrome, inflammation, and autoimmunity. Vitamin D exerts autocrine and paracrine effects such as direct intra-cellular effects via its receptors and the local production of 1,25(OH) 2 D 3 , especially in muscle and pancreatic β-cells. It also regulates calcium homeostasis and calcium flux through cell membranes, and activation of a cascade of key enzymes and cofactors associated with metabolic pathways. Cross-sectional, observational, and ecological studies reported inverse correlations between vitamin D status with hyperglycemia and glycemic control in patients with T2D, decrease the rate of conversion of prediabetes to diabetes, and obesity. However, no firm conclusions can be drawn from current studies, because (A) studies were underpowered; (B) few were designed for glycemic outcomes, (C) the minimum (or median) serum 25(OH) D levels achieved are not measured or reported; (D) most did not report the use of diabetes medications; (E) some trials used too little (F) others used too large, unphysiological and infrequent doses of vitamin D; and

    Full Text Available Obesity is a chronic metabolic disease affecting adults and children worldwide. It has become one of the leading causes of death, as obesity is known to be the main risk factor for a number of non-communicable diseases, in particular type 2 diabetes. This close relationship led to the connotation ‘diabesity', highlighting the fact that the majority of individuals with diabetes are overweight or obese. Until today the BMI is still used to classify overweight and obesity. Since reduced muscle mass is highly prevalent throughout the BMI range, the measurement of body composition is strongly recommended. Moreover, it is essential for monitoring the course of weight reduction, which is part of every effective anti-obesity treatment. Weight reduction can be achieved via different weight loss strategies, including lifestyle intervention (diet and exercise, pharmacotherapy, or bariatric surgery. However, not all of these strategies are suitable for all patients, and any further needs should be considered. Besides, attention should also be drawn to concomitant therapies. These therapies may promote additional weight gain and further trigger the deterioration of blood glucose control. Thus, therapeutic strategies are warranted, which can be easily used for the management of obese patients with type 2 diabetes to achieve their glycemic and weight loss goals.

    2013-01-01

    Full Text Available Spontaneously Diabetic Torii Leprfa (SDT fatty rat, established by introducing the fa allele of the Zucker fatty rat into SDT rat genome, is a new model of obese type 2 diabetes. Both male and female SDT fatty rats show overt obesity, and hyperglycemia and hyperlipidemia are observed at a young age as compared with SDT rats. With early incidence of diabetes mellitus, diabetic complications, such as nephropathy, retinopathy, and neuropathy, in SDT fatty rats were seen at younger ages compared to those in the SDT rats. In this paper, we overview pathophysiological features in SDT fatty rats and also describe new insights regarding the hematology, blood pressure, renal complications, and sexual dysfunction. The SDT fatty rats showed an increase of leukocytes, especially the monocyte count, prominent hypertension associated with salt drinking, end-stage renal disease with aging, and hypogonadism. Unlike other diabetic models, the characteristic of SDT fatty rat is to present an incidence of diabetes in females, hypertension, and retinopathy. SDT fatty rat is a useful model for analysis of various metabolic disorders and the evaluation of drugs related to metabolic disease.

    Full Text Available Background: The independent and combined associations of muscle strength and obesity on the prevalence of type 2 diabetes in Japanese men remain unclear. Methods: Hand grip strength was cross-sectionally evaluated between 2011 and 2013 to assess muscle strength in 5039 male workers aged 40 to 64 years. Weight and height were measured, and overweight/obesity was defined as a body mass index ≥25 kg/m2. The prevalence of type 2 diabetes, defined as fasting plasma glucose ≥126 mg/dL and/or hemoglobin A1c ≥6.5% and/or self-reported physician-diagnosed diabetes, was evaluated. Odds ratios (OR and 95% confidence intervals (95% CI for the prevalence of type 2 diabetes were obtained using a logistic regression model. Results: In total, 611 participants had type 2 diabetes, and 1763 participants were overweight/obese. After adjustment for covariates, we found an inverse association between muscle strength and the prevalence of type 2 diabetes (P for trend <0.01. In addition, when the analyses were stratified by obesity status, the multivariable-adjusted OR per 2-standard-deviation increase in muscle strength was 0.64 (95% CI, 0.49–0.83 in the overweight/obese group, compared to a weaker relationship in the normal-weight group (OR 0.79 per 2-standard-deviation increase; 95% CI, 0.60–1.06. Conclusions: Dynapenia, an age-related decrease in muscle strength, is associated with increased prevalence of type 2 diabetes, and this relationship is stronger in overweight/obese middle-aged Japanese men than in normal-weight men.

    Gastric emptying of technetium labeled liquid meal were studied in 46 non-insulin-dependent diabetics, 7 obese patients, 8 anorexia nervosa patients, and 21 normal subjects. All subjects underwent endoscopy and barium study, and none showed any lesion in upper gastrointestinal tract. T1/2, time at which 50% of meal remained, was used as an indicator of gastric emptying. Eight normal subjects have some epigastric discomforts, and have slightly slower gastric emptying than the remaining 13 subjects. But there was no significant difference in T1/2 between the both groups (53.2±12.8 min vs 45.1±10.9 min). Fourteen diabetics have some epigastric discomforts, and have significantly more slower gastric emptying than the remaining 32 diabetics (T1/2; 67.7±24.6 vs 50.5±17.4, p<0.02). The gastric emptying of 13 diabetics who have three major diabetic complications (retinopathy, nephropathy, and peripheral neuropathy), was significantly more slower than that of 15 diabetics without any complication (T1/2; 68.1±24.6 vs 43.5±14.8, p<0.005). The gastric emptying of simple obesity did not show a fixed pattern, but the emptying of anorexia nervosa was remarkably delayed. These findings indicate that diabetic gastroparesis is common in the presence of the three major complications, and the delayed gastric emptying is associated with post-prandial discomfort in diabetics and anorexia nervosa patients. The measurement of gastric emptying can be useful to evaluate the management and the treatment for diabetes and anorexia nervosa. (author)

    Ethnic differences in lipid profiles exist in children and adolescents. This study assessed whether variations in lipid profiles present in overweight and obese youth were also observed in severely obese youth. Variations could explain the lower prevalence of the metabolic syndrome in certain ethnic groups at even severe levels of obesity. Data were obtained from the National Health and Nutrition Examination Survey for the years of 2001 through 2012. Subjects were divided into groups according to BMI classification. Normal weight was defined as a BMI less than the 85th percentile. Overweight was defined as a BMI between the 85th and 95th percentile. Class 1 obesity was defined as a BMI greater than the 95th percentile up to 120% of the 95th percentile. A BMI between 120% and 140% of the 95th percentile was defined as Class 2 obesity. Class 3 was defined as a BMI above 140% of the 95th percentile. Primary outcomes were mean total cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein levels (HDL). The sample included 14,481 non-Hispanic black (NHB) (N = 4710), non-Hispanic white (N = 4910), and Mexican American (N = 4861) subjects. Across all BMI categories, the NHB group had significantly lower mean TG and higher mean HDL levels (p Ethnic variations in lipid profiles were found in severely obese youth. These findings could explain the lower prevalence of the metabolic syndrome in NHB youth. Ethnic-specific guidelines are necessary for improved identification of those at risk at all levels of obesity.

    Obesity is a key risk for the development of hyperglycemia, hypertension, hyperlipidemia, insulin resistance and is totally referred to as the metabolic disorders. Diabetes mellitus, a metabolic disorder, is related with hyperglycemia, altered metabolism of lipids, carbohydrates and proteins. The minimum defining characteristic feature to identify diabetes mellitus is chronic and substantiated elevation of circulating glucose concentration. In this study, it is aimed to determine the body composition analyze of obese and (obese+diabetes) patients.We studied the datas taken from three independent groups with the body composition analyzer instrument. The body composition analyzer calculates body parameters, such as body fat ratio, body fat mass, fat free mass, estimated muscle mass, and base metabolic rate on the basis of data obtained by Dual Energy X-ray Absorptiometry using Bioelectrical Impedance Analysis. All patients and healthy subjects applied to Siirt University Medico and their datas were taken. The Statistical Package for Social Sciences version 21 was used for descriptive data analysis. When we compared and analyzed three groups datas, we found statistically significant difference between obese, (obese+diabetes) and control groups values. Anova test and tukey test are used to analyze the difference between groups and to do multiple comparisons. T test is also used to analyze the difference between genders. We observed the statistically significant difference in age and mineral amount p<0.00 between (diabetes+obese) and obese groups. Besides, when these patient groups and control group were analyzed, there were significant difference between most parameters. In terms of education level among the illiterate and university graduates; fat mass kg, fat percentage, internal lubrication, body mass index, water percentage, protein mass percentage, mineral percentage p<0.05, significant statistically difference were observed.

    To evaluate the association between blood sugar level and obesity, and the interplay of socioeconomic change, and to investigate the efficacy of different obesity indices and age in predicting diabetes. Cross-sectional study was carried out among 603 adult Tangkhul Nagas of NE India. Anthropometric measurements, random blood sugar level, general and regional obesity indices were evaluated along with their information on socioeconomic and lifestyle factors. Socioeconomic change observed among the Tangkhuls influence the rise of overweight/obesity and blood sugar level. Obesity and elevated blood sugar level were highly prevalent and interrelated. Diabetes and obesity were also found to be associated with age. Central obesity indices were highly associated with blood sugar level. Odds ratio showed the likelihood of developing prediabetes/diabetes among centrally obese participants. Correlation between blood sugar level, age and obesity indices showed that waist hip ratio had the highest correlation with blood sugar. It implies the higher reliability of central obesity than general obesity or age in determining blood sugar level. The transition of the Tangkhul Naga tribe in terms of socioeconomic and lifestyle factors contributes to the escalating prevalence of overweight/obesity and diabetes. The rising epidemic is not restricted to highly urbanized societies but now has penetrated even to traditional and transitional tribes owing to their changing lifestyle. Different facets of the complex associations between obesity, age, diabetes and socioeconomic change were observed. Central obesity indicator, waist hip ratio emerge as the paramount predictors of prediabetes/diabetes.

    Full Text Available It is known that the metabolic syndrome has a multi-factorial basis involving both genetic and environmental risk factors. In this study, Tsumura Suzuki Obese Diabetes (TSOD mice, a mouse model of multi-factorial, hereditary, obese type II diabetes, were given a Western diet (WTD as an environmental factor to prepare a disease model (TSOD-WTD and to investigate the preventive effects of Pine bark extract (Flavangenol against obesity and various features of metabolic disease appearing in this animal model. In contrast to control Tsumura Suzuki Non-obesity (TSNO mice, TSOD mice were obese and suffered from other metabolic complications. WTD-fed TSOD mice developed additional features such as hyperinsulinemia, abnormal glucose/lipid metabolism and fatty liver. The treatment with Flavangenol had a suppressive effect on increase in body weight and accumulation of visceral and subcutaneous fat, and also showed preventive effects on symptoms related to insulin resistance, abnormal glucose/lipid metabolism and hypertension. Flavangenol also increased the plasma concentration of adiponectin and decreased the plasma concentration of TNF-α. We next investigated the effect of Flavangenol on absorption of meal-derived lipids. Flavangenol suppressed absorption of neutral fat in an olive-oil-loading test (in vivo and showed an inhibitory effect on pancreatic lipase (in vitro. The above results suggest that Flavangenol has a preventive effect on severe metabolic disease due to multiple causes that involve both genetic and environmental risk factors. The mechanism of action might involve a partial suppressive effect of meal-derived lipids on absorption.

    To investigate factors that may be associated with urinary incontinence (UI) in abdominal obese and non-obese adult males. Data were analyzed for 2671 men (≥40 years of age) who participated in the National Health and Nutrition Examination Survey (2005-2008). We define abdominal obesity as a waist circumference >102 cm. Men with Incontinence Severity Index ≥3 were defined as having UI. Logistic regression analyses were used to identify factors associated with stress and urge UI. Multivariate analysis found that in abdominal obese men, stress UI was associated with enlarged prostate (odds ratio [OR] = 2.20, 95% confidence interval [CI]: 1.16-4.16), chronic respiratory tract disease (OR = 2.78, 95% CI: 1.55-4.97), and major depression (OR = 4.79, 95% CI: 1.79-12.84). In non-obese men, arthritis was associated with stress UI (odds ratio = 3.37, 95% CI: 1.06-10.73). Urge UI in abdominally obese men was associated with age ≥65 years (OR = 1.67, 95% CI: 1.05-2.67), being non-Hispanic black (OR = 1.63, 95% CI: 1.06-2.52), and with enlarged prostate (OR = 2.30, 95% CI: 1.54-3.40), arthritis (OR = 1.39, 95% CI: 1.03-1.88), and major depression (OR = 2.96, 95% CI: 1.89-4.64). Urge UI in non-obese men was associated with current smoking (OR = 1.79, 95% CI: 1.01-3.17), major depression (OR = 2.60, 95% CI: 1.33-5.09) and vitamin D deficiency (OR = 1.61, 95% CI: 1.01-2.59). Factors associated with urinary incontinence varied with abdominal obesity status and type of UI. The findings identify important contributors to urinary incontinence that clinicians should consider to help manage and effectively treat the condition.

    A large number of diabetes patients suffer from major depression and are at high risk of mortality. In view of a role of leptin in diabetes, depression and energy homeostasis, the present study concerns circulating levels of leptin in different BMI groups of un-depressed and depressed diabetes patients. Six hundred thirty male and female patients with a primary diagnosis of diabetes were grouped according to BMI and with or without clinical symptoms of depression. Age matched healthy, normal weight male and female volunteers without clinical symptoms of depression or diabetes were taken as controls. Blood samples were obtained after an overnight fast of 12 h. Serum was stored for the determination of leptin and glucose. We found that there were more female than male diabetes patients with comorbid depression. Fasting leptin was higher in normal weight non-diabetes women than men; but comparable in normal weight men and women diabetes patients. Fasting glucose levels were higher in diabetes than non diabetes groups; values were comparable in men and women. Depression was associated with a decrease and increase in leptin respectively in normal-overweight and obese men and women diabetes patients. Glucose levels were also higher in obese depressed than un-depressed diabetes patients. The results suggested that the female gender is at greater risk to comorbid diabetes with depression. Adipo-insular axis plays an important role in diabetes, associated depression and in the greater risk of the female gender to comorbid diabetes with depression.

    Full Text Available Abstract Background Obesity is a major risk factor for development and progression of hypertension and diabetes, which often coexist in obese patients. Losing weight by means of energy restriction and physical activity has been effective in preventing and managing these diseases. However, weight control behaviors among overweight/obese adults with these conditions are poorly understood. Methods Using self-reported data from 143,386 overweight/obese participants (aged ≥ 18 years in the 2003 Behavioral Risk Factor Surveillance System, we examined the proportion of overweight/obese adults who tried to lose weight and their weight control strategies by hypertension and/or diabetes status. Results Among all participants, 58% of those with hypertension, 60% of those with diabetes, and 72% of those with both diseases tried to lose weight, significantly higher than the 50% of those with neither condition (Bonferroni corrected P Conclusion The proportion of overweight/obese patients with diagnosed hypertension and/or diabetes who attempted to lose weight remains suboptimal and the weight control strategies varied significantly among these patients.

    Obesity has reached epidemic proportions world-wide and constitutes a substantial risk factor for hypertension, type 2 diabetes, cardiovascular diseases and certain cancers. So far, regulation of energy intake by dietary and pharmacological treatments has met limited success. The main interest of current research is focused on understanding the role of different pathways involved in adipose tissue function and modulation of its mass. Whole-genome sequencing studies revealed that the majority of the human genome is transcribed, with thousands of non-protein-coding RNAs (ncRNA), which comprise small and long ncRNAs. ncRNAs regulate gene expression at the transcriptional and post-transcriptional level. Numerous studies described the involvement of ncRNAs in the pathogenesis of many diseases including obesity and associated metabolic disorders. ncRNAs represent potential diagnostic biomarkers and promising therapeutic targets. In this review, we focused on small ncRNAs involved in the formation and function of adipocytes and obesity. Copyright © 2017 Elsevier B.V. All rights reserved.

    Among non-communicable chronic diseases (NCCD), diabetes and hypertension are the main cause of adult mortality worldwide. Among the members of the Organization for Economic Cooperation and Development, Mexico is first in prevalence of diabetes and second in obesity. To face this problematic situation of NCCDs the Ministry of Health declared a national epidemiological alert against the overweight, obesity and diabetes. The target of this study is to characterize the status of obesity, diabetes and hypertension in the adult population in the area of influence of primary health facilities located in high social marginality areas. We conducted a cross-sectional observational study and used a convenience sample. A survey was conducted on a population of 18 years old and above in four primary health facilities in four Mexican States. The survey explored sociodemographic characteristics, the presence of chronic diseases, the access to healthcare services, risk factors and life styles. We also applied a complementary questionnaire to 20% of the participants, in order to explore food consumption during the last week and physical activity (International Physical Activity Questionnaire). We based our analysis on descriptive statistics and logistic multivariate regression to analyze factors associated with diabetes and hypertension. 73% (n = 7531, CI 0.72-0.74) percent of the population reported being diabetic, hypertensive and/or overweight. The majority of them receive healthcare in public health services. People over 40 years old, are 11 times more probable of living with diabetes and 8.7 times more probable of living with hypertension. Both conditions affect mostly women, whose main activity is to be a housewife. People who have lunch and dinner out of home are more likely to develop diabetes. People who perform intense physical activity are less likely to live with hypertension. According to the self-report, more than 70% of adult population living in areas with high

    Plasma glucose, immunoreactive insulin (IRI) and C-peptide responses during oral glucose tolerance testing (OGTT) were evaluated in 10 non obese women with polycystic ovarian disease (NOB-PCOD) and 10 obese women with polycystic ovarian disease (OB-PCOD). Mean plasma glucose response at 120 minutes in OB-PCOD showed impaired glucose tolerance. Also in this group, 1 patient had frank diabetes mellitus, whilst 3 other patients had impaired glucose tolerance 1 NOB-PCOD patient had impaired glucose tolerance. Mean plasma glucose levels and mean incremental glucose areas were higher in the OB-PCOD at all time intervals and reached statistical significance at 60 and 90 minutes. Mean plasma IRI levels were also higher in OB-PCOD at all time intervals, and reached statistically significant higher levels at 0, 60 and 90 minutes. Mean serum C-peptide valves were also higher at all time intervals in OB-PCOD. The relationship between acanthosis nigricans, obesity and PCOD was also analysed. It is evident from this study that obesity has a significant negative impact on the overall carbohydrate status in women with PCOD.

    Full Text Available Aim: This study aimed to investigate the effects of red ginseng extract (RGE on adiposity index, some serum biochemical parameters and tissue antioxidant activity in obese diabetic rats. Materials and Methods: Five groups of male Sprague-Dawley rats were used. Group (1 was negative control and the other 4 groups were fed on high fat-diet for 6 weeks to induce obesity. The obese rats were then rendered diabetic by intraperitoneal injection of alloxan for 5 days. Group (2 was kept obese diabetic (positive control and the other 3 groups were orally given RGE at 100, 200 and 400 mg /kg /day, respectively, for 4 weeks. Blood samples were collected for biochemical analyses and kidneys were taken to assay of activities of antioxidant enzymes. Results: oral dosage of RGE to obese diabetic rats significantly (P < 0.05 reduced adiposity index; decreased serum levels of aspartate aminotransferase (AST, alanine aminotransferase (ALT, gamma- glutamyl transpeptidase (GGT enzymes, total cholesterol (TC, triglycerides (TG, and low density lipoproteins (LDL-c and improved atherogenic index. Blood glucose and leptin hormone decreased, but insulin increased by administration of RGE. it increased activities of superoxide dismutase (SOD, glutathione peroxidase (GPx and catalase (CAT antioxidant enzymes in kidneys tissues. Conclusion: Red ginseng extract produces antiobesity, antioxidant, and antidiabetic activities in obese diabetic rats. The study suggests that red ginseng plant may be beneficial for the treatment of patients who suffer from obesity associated with diabetes. [J Intercult Ethnopharmacol 2013; 2(3.000: 165-172

Our results suggest that one group affects the general capacity of the ED to provide care as they persistently present with severe episodes requiring urgent staff attention and greater resource allocation. Another group persistently presents with non-severe episodes and creates a considerable share of the excess demand for ED care. Future research should determine how chronic disease management programs and varied co-payment obligations might impact the use of the ED by these two large and distinct groups of older adults with consistent ED use patterns.

    Full Text Available Abstract Background Leucine may function as a signaling molecule to regulate metabolism. We have previously shown that dietary leucine supplementation significantly improves glucose and energy metabolism in diet-induced obese mice, suggesting that leucine supplementation could potentially be a useful adjuvant therapy for obesity and type 2 diabetes. Since the underlying cause for obesity and type 2 diabetes is multifold, we further investigated metabolic effects of leucine supplementation in obese/diabetes mouse models with different etiologies, and explored the underlying molecular mechanisms. Methods Leucine supplementation was carried out in NONcNZO10/LtJ (RCS10 - a polygenic model predisposed to beta cell failure and type 2 diabetes, and in B6.Cg-Ay/J (Ay - a monogenic model for impaired central melanocortin receptor signaling, obesity, and severe insulin resistance. Mice in the treatment group received the drinking water containing 1.5% leucine for up to 8 months; control mice received the tap water. Body weight, body composition, blood HbA1c levels, and plasma glucose and insulin levels were monitored throughout and/or at the end of the study period. Indirect calorimetry, skeletal muscle gene expression, and adipose tissue inflammation were also assessed in Ay mice. Results Leucine supplementation significantly reduced HbA1c levels throughout the study period in both RCS10 and Ay mice. However, the treatment had no long term effect on body weight or adiposity. The improvement in glycemic control was associated with an increased insulin response to food challenge in RCS10 mice and decreased plasma insulin levels in Ay mice. In leucine-treated Ay mice, energy expenditure was increased by ~10% (p y mice whereas the expression levels of MCP-1 and TNF-alpha and macrophage infiltration in adipose tissue were significantly reduced.

    Obesity is becoming an epidemic health problem. During the last years not only genetic but also, and primarily, environmental factors have been supposed to contribute to the susceptibility to weight gain or to develop complications such as type 2 diabetes. In spite of the intense efforts to identify genetic predisposing variants, progress has been slow and success limited, and the common obesity susceptibility variants identified only explains a small part of the individual variation in risk. Moreover, there is evidence that the current epidemic of obesity and diabetes is environment-driven. Recent studies indicate that normal metabolic regulation during adulthood besides requiring a good balance between energy intake and energy expenditure, can be also affected by pre- and post-natal environments. In fact, maternal nutritional constraint during pregnancy can alter the metabolic phenotype of the offspring by means of epigenetic regulation of specific genes, and this can be passed to the next generations. Studies focused on epigenetic marks in obesity found altered methylation and/or histone acetylation levels in genes involved in specific but also in more general metabolic processes. Recent researches point out the continuous increase of "obesogens", in the environment and food chains, above all endocrine disruptors, chemicals that interfere with many homeostatic mechanisms. Taken into account the already existing data on the effects of obesogens, and the multiple potential targets with which they might interfere daily, it seems likely that the exposure to obesogens can have an important role in the obesity and diabesity pandemic.

    VEGF is one the pro-inflammatory adipokines synthesized by the "adipose secretoma" of obese subjects as a response to hypoxic conditions; but the main function of VEGF is angiogenesis, being recognized as the most important factor increasing blood capillaries in the adipose tissue by stimulating endothelial cell growth. In this paper, we propose a comparative study of the vascular response to VEGF synthesis in the subcutaneous and central-peritoneal adipose depots in lean, obese and obese diabetic patients. We used CD31 to label the endothelial cells in order to evaluate the response of the vascular network to VEGF synthesis. Our results showed an increase of VEGF protein synthesis in obese and obese-diabetic patients compared to lean subjects where the protein was absent. The positivity for VEGF in obese diabetic samples was observed in numerous structures from the adipose depots, both in the stromal vascular fraction--blood vessels and stromal cells--as well as in the cytoplasm of adipocytes. Positivity in the vascular wall was observed more frequently in areas of perivascular and intralobular fibrosis. Obese and diabetic patients showed similar incidence of CD31 immunoreactivity with lean subjects in both subcutaneous and peritoneal depots. In conclusion, human adipose depots show a different incidence of VEGF positive cells in relation with their disposal and the metabolic status. VEGF synthesis in visceral adipose tissue is inefficient being not followed by angiogenesis to counterbalance tissue hypoxia. We suggest that may be a pathogenic link between the degrees of intralobular fibrosis in adipose depots and VEGF expression.

    Prenatal maternal obesity has been linked to adverse childhood neuropsychiatric outcomes, including increased symptoms of attention deficit hyperactivity disorder (ADHD), internalizing and externalizing problems, affective disorders and neurodevelopmental problems but few studies have studied neuropsychiatric outcomes among offspring born to very severely obese women or assessed potential familial confounding by maternal psychological distress. We evaluated neuropsychiatric symptoms in 112 children aged 3-5 years whose mothers had participated in a longitudinal study of obesity in pregnancy (50 very severe obesity, BMI ⩾40 kg/m2, obese class III and 62 lean, BMI 18.5-25 kg/m2). The mothers completed the Conners' Hyperactivity Scale, Early Symptomatic Syndrome Eliciting Neurodevelopmental Clinical Examination Questionnaire (ESSENCE-Q), Child's Sleep Habits Questionnaire (CSHQ), Strengths and Difficulties Questionnaire (SDQ), and Child Behavior Checklist (CBCL) to assess child neuropsychiatric symptoms. Covariates included child's sex, age, birthweight, gestational age, socioeconomic deprivation levels, maternal age, parity, smoking status during pregnancy, gestational diabetes and maternal concurrent symptoms of anxiety and depression assessed using State Anxiety of Spielberger State-Trait Anxiety Index (STAI) and General Health Questionnaire (GHQ), respectively. Children exposed to prenatal maternal very severe obesity had significantly higher scores in the Conners' Hyperactivity Scale; ESSENCE-Q; total sleep problems in CSHQ; hyperactivity, conduct problems and total difficulties scales of the SDQ; higher externalizing and total problems, anxious/depressed, aggressive behaviour and other problem syndrome scores and higher DSM-oriented affective, anxiety and ADHD problems in CBCL. Prenatal maternal very severe obesity remained a significant predictor of child neuropsychiatric problems across multiple scales independent of demographic factors, prenatal factors and

    Maternal obesity and diabetes dramatically increase the long-term risk for obesity in the next generation, and pregnancy and lactation may be critical periods at which to aim primary prevention to break the obesity cycle. It is becoming increasingly clear that the gut microbiome in newborns and infants plays a significant role in gut health and therefore child development. Alteration of the early infant gut microbiome has been correlated with the development of childhood obesity and autoimmune conditions, including asthma, allergies and, more recently, type 1 diabetes. This is likely to be due to complex interactions between mode of delivery, antibiotic use, maternal diet, components of breastfeeding and a network of regulatory events involving both the innate and adaptive immune systems within the infant host. Each of these factors are critical for informing microbiome development and can affect immune signalling, toxin release and metabolic signals, including short-chain fatty acids and bile acids, that regulate appetite, metabolism and inflammation. In several randomised controlled trials, probiotics have been administered with the aim of targeting the microbiome during pregnancy to improve maternal and infant health but the findings have often been confounded by mode of delivery, antibiotic use, ethnicity, infant sex, maternal health and length of exposure. Understanding how nutritional exposure, including breast milk, affects the assembly and development of both maternal and infant microbial communities may help to identify targeted interventions during pregnancy and in infants born to mothers with obesity or diabetes to slow the transmission of obesity risk to the next generation. The aim of this review is to discuss influences on infant microbiota colonisation and the mechanism(s) underlying how alterations due to maternal obesity and diabetes may lead to increased risk of childhood obesity.

    To describe the clinical characteristics of non-English speaking patients from the Diabetes Management Project (NEDMP), and compare their diabetes management and severity of diabetic retinopathy (DR) with the English-speaking DMP sample (EDMP). A prospective study was conducted on non-English speaking adults with diabetes who attended the Royal Victorian Eye and Ear Hospital. 136 (90.1%) non-English speaking adults were assessed, with a mean age of 72.2 years (range: 50-88 years); 74 (54.4%) were male. Participants completed interviewer-administered questionnaires and underwent visual acuity, fundus photography, optical coherence tomography, biochemistry and anthropometric measurements. The EDMP assessed 609 patients in 2009 using a similar protocol. Type and duration of diabetes, diabetes control and diabetic retinopathy. A total of 127 (93.4%) and 8 (5.9%) participants reported having type 2 and type 1 diabetes, respectively, with a median (IQR) duration of 17 (14) years. The proportion of patients with poor diabetes control (HbA1c ≥ 7%) in the NEDMP was similar to the EDMP (64.0% and 68.2%, respectively; P = 0.411). A significantly higher proportion of patients with DR in the NEDMP were found to have poor diabetes control (HbA1c ≥ 7%) compared to those without DR (80.9% vs. 50.0%, P = 0.003). Almost two-thirds of NEDMP patients (74/118) had DR and 23% (27/115) had diabetic macular edema. The prevalence of DR was similar between the NEDMP and EDMP studies, ranging from 25-30% and 28-29%. The clinical characteristics, diabetes control, and DR severity of English and non-English-speaking patients were similar. The high proportion of poor diabetes management in non-English speaking patients with DR suggests educational and behavioural interventions to improve glycaemic control are warranted. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

    Nonalcoholic fatty liver disease (NAFLD) has become a public health concern. It encompasses a wide spectrum of histological abnormalities and has close relationships with insulin resistance and type 2 diabetes mellitus (T2DM). This study sought to compare the histological alterations observed in morbidly obese individuals with and without T2DM who underwent Roux-en-Y gastric bypass. Cross-sectional study in a tertiary-level public hospital. This was a cross-sectional study on 197 individuals who underwent gastric bypass surgery between 2011 and 2013. NAFLD was assessed through liver biopsies. T2DM was diagnosed through the International Diabetes Federation criteria. Non-diabetics presented significantly more biopsies without any histological abnormalities, regarding steatosis (42.6% versus 25.5%; P = 0.0400), fibrosis (60.6% versus 36.2%; P = 0.0042) and steatohepatitis (27.3% versus 12.8%; P = 0.0495), while diabetics presented significantly higher frequency of moderate forms of steatosis (36.2% versus 20%; P = 0.0307) and fibrosis (23.4% versus 4%; P = 0.0002). T2DM was associated with more advanced forms of NAFLD within the population studied. NAFLD has previously been correlated with severe forms of heart disease. Screening for and early detecting of NAFLD in high-risk populations are important for avoiding further development of severe forms and the need for liver transplantation.

    Recent studies suggest that prevalence of diagnosed diabetes in the United States reached a plateau or slowed around 2008, and that this change coincided with obesity plateaus and increases in physical activity. However, national estimates can obscure important variations in geographic subgroups. We examine whether a slowing or leveling off in diagnosed diabetes, obesity, and leisure time physical inactivity prevalence is also evident across the 3143 counties of the United States. We used publicly available county estimates of the age-adjusted prevalence of diagnosed diabetes, obesity, and leisure-time physical inactivity, which were generated by the Centers for Disease Control and Prevention (CDC). Using a Bayesian multilevel regression that included random effects by county and year and applied cubic splines to smooth these estimates over time, we estimated the average annual percentage point change (APPC) from 2004 to 2008 and from 2008 to 2012 for diabetes, obesity, and physical inactivity prevalence in each county. Compared to 2004-2008, the median APPCs for diabetes, obesity, and physical inactivity were lower in 2008-2012 (diabetes APPC difference = 0.16, 95%CI 0.14, 0.18; obesity APPC difference = 0.65, 95%CI 0.59, 0.70; physical inactivity APPC difference = 0.43, 95%CI 0.37, 0.48). APPCs and APPC differences between time periods varied among counties and U.S. regions. Despite improvements, levels of these risk factors remained high with most counties merely slowing rather than reversing, which suggests that all counties would likely benefit from reductions in these risk factors. The diversity of trajectories in the prevalence of these risk factors across counties underscores the continued need to identify high risk areas and populations for preventive interventions. Awareness of how these factors are changing might assist local policy makers in targeting and tracking the impact of efforts to reduce diabetes, obesity and physical inactivity.

    Full Text Available Objective: The primary objective of this study was to compare serum NPY and leptin levels between non-pregnant and pregnant women in overall, non-obese, and obese subjects. The secondary objective was to compare these peptides between non-obese and obese pregnant women. Methods: Fasting venous blood was collected from non-pregnant women before open abdominal surgery and from pregnant women when admitted to the delivery room during the latent phase of labor. Results: There were 12 non-obese and 14 obese subjects in the non-pregnant group and 9 non-obese and 30 obese subjects in the pregnant group. Systolic blood pressure (SBP was comparable, but heart rate (HR was higher in pregnant compared to non-pregnant women. Mean±S.E.M serum NPY levels were lower in the pregnant than in the non-pregnant group in overall (0.54±0.02 and 1.34±0.08, respectively, non-obese (0.53±0.05 and 1.23±0.14, respectively, and obese (0.54±0.03 and 1.43±0.09, respectively subjects (p<0.01 for all, but these were comparable between obese and non- obese pregnant subjects. Serum NPY was positively correlated with SBP (R=0.281, p<0.05, but negatively correlated with HR (R=-0.324, p<0.01. Serum leptin levels were not different between pregnant and non-pregnant groups, but were significantly higher in obese than non-obese pregnant subjects (p<0.001. Serum leptin levels were positively correlated with body weight, BMI, waist and hip circumferences in overall and pregnant subjects (p<0.001 all. Conclusion: In pregnancy, decreased NPY levels might be associated with inhibition of SBP rising as well as increased HR. Leptin levels might not be associated with pregnancy, but associated mainly with obesity.

    Oral health status must be considered in the care of children with obesity (OB) and diabetes mellitus (DM). The health of these patients' mouths may have significant effects on their overall health and evolution of their disease. Here we address periodontal disease (PD) and dental caries (DC), since these are two of the most common chronic diseases affecting OB and DM patients. OB plays a plausible role in the development of PD. Both overall OB and central adiposity are associated with increased hazards of gingivitis and its progression to PD. The inflammatory changes of PD might not be limited to the oral cavity, these may also trigger systemic consequences. Patients with type 1 and type 2 diabetes mellitus (T1DM, T2DM) present an increased prevalence of gingivitis and PD. In diabetics PD develops at a younger age than in the healthy population, it also worsens with the prolongation of DM. The progression to PD has been correlated with the metabolic control of the disease as it is more prevalent and more severe in patients with elevated hemoglobin A1c (A1c) levels. PD negatively affects glycemic control and other diabetes related complications and there is a general consensus that treatment of PD can positively influence these negative effects. Additionally, DC is a multifactorial oral disease that is frequently detected in those with OB and DM, although its prevalence in systematic reviews is inconclusive. The associations between gingivitis, PD and DC share similar behaviors, i.e. inadequate oral hygiene habits and unhealthy dietary intake. Insufficient tooth brushing and intake of sugary foods may result in greater detrimental oral effects. Maintaining oral health will prevent oral chronic diseases and ameliorate the consequences of chronic inflammatory processes. Thus, the care of obese and diabetic patients requires a multidisciplinary team with medical and dental health professionals. Copyright© of YS Medical Media ltd.

    To summarize recent studies about obesity, insulin resistance, and type 1 diabetes mellitus (T1DM). Overweight and obesity continue to be prevalent among individuals with T1DM. Obesity rates appear to have reached a plateau among children with T1DM in some parts of the world. The risk for development of T1DM is increased by obesity and may occur at an earlier age among obese individuals with a predisposition. Obesity increases the risk for comorbidities among individuals with T1DM, especially metabolic syndrome, and microvascular and macrovascular diseases. Metformin, glucagon-like peptide-1 agonist therapy, sodium glucose cotransporter-2 inhibitor therapy, and bariatric surgery may be beneficial therapies for glucose control, comorbidity management, and obesity among adults with T1DM. Insulin resistance may be improved among obese individuals with T1DM by biguanides (metformin) and glucagon-like peptide-1 agonists (exenatide). We review the last 18 months of literature on obesity, insulin resistance, and T1DM to highlight new epidemiologic results and treatments.

    Introduction: Chronically altered glucose metabolism interferes with 18 F-FDG uptake in malignant tissue and healthy organs and may therefore lower tumor detection in 18 F-FDG PET/CT. The present study assesses the impact of elevated blood glucose levels (BGL), diabetes, insulin treatment, and obesity on 18 F-FDG uptake in tumors and biodistribution in normal organ tissues. Methods: 18 F-FDG PET/CT was analyzed in 90 patients with BGL ranging from 50 to 372 mg/dl. Of those, 29 patients were diabetic and 21 patients had received insulin prior to PET/CT; 28 patients were obese with a body mass index > 25. The maximum standardized uptake value (SUV max ) of normal organs and the main tumor site was measured. Differences in SUV max in patients with and without elevated BGLs, diabetes, insulin treatment, and obesity were compared and analyzed for statistical significance. Results: Increased BGLs were associated with decreased cerebral FDG uptake and increased uptake in skeletal muscle. Diabetes and insulin diminished this effect, whereas obesity slightly enhanced the outcome. Diabetes and insulin also increased the average SUV max in muscle cells and fat, whereas the mean cerebral SUV max was reduced. Obesity decreased tracer uptake in several healthy organs by up to 30%. Tumoral uptake was not significantly influenced by BGL, diabetes, insulin, or obesity. Conclusions: Changes in BGLs, diabetes, insulin, and obesity affect the FDG biodistribution in muscular tissue and the brain. Although tumoral uptake is not significantly impaired, these findings may influence the tumor detection rate and are therefore essential for diagnosis and follow-up of malignant diseases

    Synchrony of biological processes with environmental cues developed over millennia to match growth, reproduction and senescence. This entails a complex interplay of genetic, metabolic, chemical, light, hormonal and hedonistic factors across life forms. Sleep is one of the most prominent rhythms where such a match is established. Over the past 100 years or so, it has been possible to disturb the synchrony between sleep-wake cycle and environmental cues. Development of electric lights, shift work and continual accessibility of the internet has disrupted this match. As a result, many non-communicable diseases such as obesity, insulin resistance, type 2 diabetes, coronary artery disease and malignancies have been attributed in part to such disruption. In this presentation a review is made of the origin and evolution of sleep studies, the pathogenic mediators for such asynchrony, clinical evidence and relevance and suggested management options to deal with the disturbances.

    Higher mortality rates among morbidly obese (BMI of > or =40 or > or =35 kg/m2 with weight-related comorbidities) subjects are mainly explained by comorbidities such as type 2 diabetes. As bariatric surgery ameliorates diabetes, obese diabetic subjects will receive great benefits from bariatric surgery. Screening for diabetes prior to surgical referral is therefore crucial. We studied 1,253 consecutively recruited (2005-2008) morbidly obese subjects (67% women). Among subjects without known diabetes, 70% (670/961) performed an oral glucose tolerance test (OGTT). Screen-detected diabetes was defined as fasting plasma glucose (fPG) > or =7.0 mmol/l and/or 2-h glucose concentration (2hPG) > or = 11.1 mmol/l. Within the study population, 31% had diabetes, of which 8% were screen-detected. Eighty percent of those with screen-detected diabetes were diagnosed by fPG. In subjects with nondiabetic fPG concentrations, elevating the fPG cutoff value from 5.2 mmol/l to the World Health Organization's (WHO's) recommended value of 6.1 mmol/l reduced the percentage of the population needing an OGTT considerably (78-23%), but only slightly reduced the sensitivity of fPG in detecting a diabetic 2hPG concentration (100-77%). Only 7% of the patients with fPG between 6.1 and 6.9 mmol/l had a diabetic 2hPG concentration. Following the WHO's recommendations, we found that 95% of all subjects with unknown diabetes were identified. Fasting glucose identified four out of five morbidly obese subjects with unknown diabetes. A supplemental OGTT in selected persons identified the majority of the remaining diabetic cases.

    Data on the potential effect of obesity and diabetes mellitus on survival after liver resection due to colorectal cancer (CRC) metastases are very limited. Patients undergoing liver resection for CRC metastases in a European institution in 2004-2011 were retrospectively enrolled. Relevant data, such as body mass index, extent of resection, chemotherapy, and perioperative outcome, were collected from medical records. The relation of obesity and diabetes mellitus with overall and disease-free survival was assessed using adjusted Cox models. Thirty of 207 patients (14.4%) included in the study were obese (BMI ≥30 kg/m(2)) and 25 (12%) had diabetes mellitus. Major hepatectomy was performed in 46%. Although both obese patients and those with diabetes had higher American Society of Anesthesiologist scores (P diabetes was significantly related to primary tumor characteristics, liver metastasis features, extent or radicality of resection, extrahepatic disease at hepatectomy, preoperative or postoperative oncologic therapy, or perioperative outcome (P > 0.05 for all). Patients were followed up for a median of 39 mo posthepatectomy (interquartile range, 13-56 mo). After adjustment for confounders, obesity was an independent predictor of improved (hazard ratio, 0.305, 95% confidence interval, 0.103-0.902) and diabetes of worse overall survival (hazard ratio, 3.298, 95% confidence interval, 1.306-8.330).

    Diabetes mellitus (DM) in dogs is a common endocrinopathy with a complex genetic architecture. Disease susceptibility in several breeds is associated with polymorphisms in immune response genes, but in the Labrador retriever breed, no genetic associations with DM have been identified. A deletion in the pro-opiomelanocortin (POMC) gene in Labrador retrievers is associated with increased appetite and risk of obesity. To characterize the POMC deletion in Labrador retrievers, to develop a simple genetic test for this mutation, and to test the hypothesis that the POMC gene deletion is associated with an increased risk of DM in this breed. Sixty-one non-diabetic Labrador retrievers aged >6 years and 57 Labrador retrievers with DM. Case-control genotyping study to compare the frequency of the POMC deletion in dogs with and without DM. After polymerase chain reaction (PCR) and sequencing to characterize the mutation, a PCR-based test was developed and validated using 2 different restriction fragment length polymorphism assays. A 14-base-pair deletion was confirmed and localized to exon 3 of the canine POMC gene. A PCR-based test for the deletion was successfully developed. There was no association between the presence of the POMC deletion mutation and DM in this population of Labrador retriever dogs (P = .31).

    Obese insulin resistance and type 2 diabetes mellitus profoundly impair bone mechanical properties and bone quality. However, because several antidiabetes drugs, especially thiazolidinediones, further aggravate bone loss in individuals with diabetes, diabetic osteopathy should not be treated by using simply any glucose-lowering agents. Recently, incretins have been reported to affect osteoblast function positively. The present study aimed to investigate the effects of vildagliptin, an inhibitor of dipeptidyl peptidase-4, on bone of rats with high-fat-diet-induced prediabetes. Male rats were fed a high-fat diet for 12 weeks to induce obese insulin resistance and then treated with vildagliptin for 4 weeks. The effects of the drug on bone were determined by microcomputed tomography and bone histomorphometry. Vildagliptin markedly improved insulin resistance in these obese insulin-resistant rats. It also significantly increased volumetric bone mineral density. Specifically, vildagliptin-treated obese insulin-resistant rats exhibited higher trabecular volumetric bone mineral density than vehicle-treated obese insulin-resistant rats, whereas cortical volumetric bone mineral density, cortical thickness and area were not changed. Bone histomorphometric analysis in a trabecular-rich area (i.e. tibial metaphysis) revealed greater trabecular bone volume and number and less trabecular separation without change in trabecular thickness, osteocyte lacunar area or cortical thickness in the vildagliptin-treated group. Vildagliptin had a beneficial effect on the bone of obese insulin-resistant rats with prediabetes, particularly at the trabecular site. Such benefit probably results from enhanced bone formation rather than from suppressed bone resorption. Copyright © 2018 Diabetes Canada. Published by Elsevier Inc. All rights reserved.

    Full Text Available Obesity represents a major risk factor for a plethora of severe diseases, including diabetes, cardiovascular disease, non-alcoholic fatty liver disease, and cancer. It is often accompanied by an increased risk of mortality and, in the case of non-fatal health problems, the quality of life is impaired because of associated conditions, including sleep apnea, respiratory problems, osteoarthritis, and infertility. Recent evidence suggests that oxidative stress may be the mechanistic link between obesity and related complications. In obese patients, antioxidant defenses are lower than normal weight counterparts and their levels inversely correlate with central adiposity; obesity is also characterized by enhanced levels of reactive oxygen or nitrogen species. Inadequacy of antioxidant defenses probably relies on different factors: obese individuals may have a lower intake of antioxidant- and phytochemical-rich foods, such as fruits, vegetables, and legumes; otherwise, consumption of antioxidant nutrients is normal, but obese individuals may have an increased utilization of these molecules, likewise to that reported in diabetic patients and smokers. Also inadequate physical activity may account for a decreased antioxidant state. In this review, we describe current concepts in the meaning of obesity as a state of chronic oxidative stress and the potential interventions to improve redox balance.

  8. Depression Amplifies the Influence of Central Obesity on 10-Year Incidence of Diabetes: Findings from MIDUS.

    Vera K Tsenkova

    Full Text Available Central obesity is a major risk factor for diabetes but many obese individuals never develop diabetes, suggesting the presence of important effect modifiers. Depression has emerged as a key risk factor for poor glycemic control, but to our knowledge, no previous work has investigated whether depression amplifies the effect of central obesity on glucoregulation.We used a national sample of adults without prevalent diabetes (MIDUS; N = 919 to test for synergy between central obesity and depression in the development of diabetes 10 years later. We found that depression amplified the association of waist-to-hip ratio (WHR with incident diabetes adjusted for age, race, gender, education, physical activity, and sleep problems (p = 0.01 for test of interaction. The relative risk for incident diabetes per every 0.1 increment in WHR was 1.75 (95% CI: 1.31; 2.33 in those without depression and 3.78 in those with depression (95% CI: 2.14; 6.66.These results confirm the role of depression as a robust risk factor for the development of diabetes and for the first time, demonstrate a synergy between depression and central obesity. Identifying and addressing depression could prove to be an effective approach to preventing diabetes in at risk individuals. Ultimately, elucidating the interplay among risk factors from different domains will be key to understanding multifactorial diseases such as diabetes and informing theory-based, patient-centered interventions aimed at reducing diabetes risk.

    Background: Adipokines have been implicated in the modulation of insulin sensitivity and glucose tolerance and have thus gained importance in the study of Type 2 diabetes mellitus (T2DM). Resistin, a unique signalling molecule, is being proposed as a significant factor in the pathogenesis of obesity-related insulin resistance. However, its relevance to human diabetes mellitus remains uncertain and controversial. This study was therefore planned to compare and correlate the potential role of resistin in obese patients with T2DM and obese non-diabetic controls and also to evaluate the correlation between resistin and marker of obesity and glycaemic parameters. Method: Fasting serum resistin, glucose and insulin were measured in forty obese diabetics (mean±SD BMI 35±5 kg/m2) and forty obese non-diabetics (mean±SD BMI 33±3 kg/m2). Insulin resistance was assessed using the HOMA-IR formula derived from fasting insulin and glucose levels. Results: Serum resistin levels (38±8 ng/ml) were significantly higher in type 2 diabetic patients as compared with the controls. Fasting blood glucose (164±46 mg/dl), serum insulin (37±7 μU/ml) and insulin resistance (19±8), were considerably higher among the studied diabetics than in the controls. Pearson's correlation analysis revealed positive correlation between serum resistin and BMI (p=0.001) and HOMA-IR (p=0.561) in diabetic subjects. Similarly, a correlation also existed between serum resistin and BMI (p=0.016) and HOMA-IR (p=0.307) in control obese subjects. However, it was highly significant in diabetics as compared to non-diabetic controls. Conclusion: A significant BMI-dependent association exists between resistin and insulin resistance in patients with T2DM. It appears that resistin may play a role in the pathogenesis of obesity and insulin resistance and that both of these may contribute to the development of T2DM. (author)

    Resting ischemic electrocardiographic abnormalities have been associated with cardiovascular mortality. Simple markers of abnormal autonomic tone have also been associated with diabetes, obesity, and the metabolic syndrome in some populations. Data on these electrocardiographic abnormalities and correlations with coronary risk factors are lacking among Mexican Americans wherein these conditions are prevalent. This study aimed to evaluate the prevalent resting electrocardiographic abnormalities among community-dwelling Mexican Americans, and correlate these findings with coronary risk factors, particularly diabetes, obesity, and the metabolic syndrome. Study subjects (n=1280) were drawn from the Cameron County Hispanic Cohort comprised of community-dwelling Mexican Americans living in Brownsville, Texas at the United States-Mexico border. Ischemic electrocardiographic abnormalities were defined as presence of ST/T wave abnormalities suggestive of ischemia, abnormal Q waves, and left bundle branch block. Parameters that reflect autonomic tone, such as heart rate-corrected QT interval and resting heart rate, were also measured. Ischemic electrocardiographic abnormalities were more prevalent among older persons and those with hypertension, diabetes, obesity, and the metabolic syndrome. Subjects in the highest quartiles of QTc interval and resting heart rate were also more likely to be diabetic, hypertensive, obese, or have the metabolic syndrome. Among Mexican Americans, persons with diabetes, obesity, and the metabolic syndrome were more likely to have ischemic electrocardiographic abnormalities, longer QTc intervals, and higher resting heart rates. A resting electrocardiogram can play a complementary role in the comprehensive evaluation of cardiovascular risk in this minority population.

    The effects of a carbohydrate-restricted diet on weight loss and risk factors for atherosclerosis have been incompletely assessed. We randomly assigned 132 severely obese subjects (including 77 blacks and 23 women) with a mean body-mass index of 43 and a high prevalence of diabetes (39 percent) or the metabolic syndrome (43 percent) to a carbohydrate-restricted (low-carbohydrate) diet or a calorie- and fat-restricted (low-fat) diet. Seventy-nine subjects completed the six-month study. An analysis including all subjects, with the last observation carried forward for those who dropped out, showed that subjects on the low-carbohydrate diet lost more weight than those on the low-fat diet (mean [+/-SD], -5.8+/-8.6 kg vs. -1.9+/-4.2 kg; P=0.002) and had greater decreases in triglyceride levels (mean, -20+/-43 percent vs. -4+/-31 percent; P=0.001), irrespective of the use or nonuse of hypoglycemic or lipid-lowering medications. Insulin sensitivity, measured only in subjects without diabetes, also improved more among subjects on the low-carbohydrate diet (6+/-9 percent vs. -3+/-8 percent, P=0.01). The amount of weight lost (Plow-carbohydrate diet (P=0.01) were independent predictors of improvement in triglyceride levels and insulin sensitivity. Severely obese subjects with a high prevalence of diabetes or the metabolic syndrome lost more weight during six months on a carbohydrate-restricted diet than on a calorie- and fat-restricted diet, with a relative improvement in insulin sensitivity and triglyceride levels, even after adjustment for the amount of weight lost. This finding should be interpreted with caution, given the small magnitude of overall and between-group differences in weight loss in these markedly obese subjects and the short duration of the study. Future studies evaluating long-term cardiovascular outcomes are needed before a carbohydrate-restricted diet can be endorsed. Copyright 2003 Massachusetts Medical Society

    To investigate the immunosuppressive effect of total glucosides of peony (TGP) on sialoadenitis in non-obese diabetic mice (NOD mice) and explore its possible mechanism. 27 female five-week-old NOD mice were randomly divided into three groups: TGP, hydroxychloroquine (HCQ) and normal saline (NS) group. One week later, they were administered intragastrically in TGP, HCQ and NS respectively. Three mice from each group were sacrificed at the age of 10, 15 and 20 weeks. The saliva flow, serum and submandibular glands were collected at these time points. Histological changes of submandibular glands were examined by HE staining. The expression of autoantibodies (SSA, SSB and anti-alpha-fodrin) and associated cytokines in serum were detected by enzyme-linked immunosorbent assay (ELISA). Compared with the NS group, salivary flow was significantly increased, the extent of the histological changes were ameliorated, the autoantibodies in serum were significantly decreased and the imbalance of Th1/Th2 cytokines was remedied in the mice treated with TGP and HCQ. There were no significant differences between the two groups treated with TGP and HCQ (P > 0.05). TGP can effectively ameliorate sialoadenitis on NOD mice. The mechanism was thought to be associated with the protection of submandibular gland from intense inflammation and the correction of Th1/Th2 cytokines imbalance.

    Diabetes Mellitus is now a prevalent disease in both developed and developing countries. Overweight/obesity and hypertension are potential modifiable risk factors for diabetes mellitus and persist during the course of the disease. This study was aimed at reporting the prevalence of overweight/obesity and systemic hypertension and their association to blood glucose levels in persons with diabetes mellitus attending a diabetic clinic in Ghanaian Teaching Hospital. This cross-sectional study was conducted among 100 previously diagnosed diabetes mellitus patients attending a diabetic clinic at the Tamale Teaching Hospital, Ghana. Anthropometric variables of age, weight and height were measured with appropriate instruments, computed into BMI and classified according to WHO classifications. Systolic and diastolic blood pressures were measured by an appropriate instrument and classified by WHO standards. Fasting plasma glucose levels of the study participants were recorded from their personal health folder. All data was analysed by GraphPad prism version 5. In general, 7.0% of the participants were underweight and 32.0% were overweight or obese. The mean±SD weight, height and BMI of the participants were 67.53±13.32, 1.68±0.12 and 24.18±5.32. Twenty-one percent of the studied participants were hypertensive. Mean±SD fasting plasma glucose of 7.94±2.82 was observed among the diabetic patients. As the prevalence of hyperglycaemia was higher among patients aged ≤40 years (88.9% vs. 75.8%), normoglycaemia (11.1% vs. 24.2%) was higher among those over 40 years. The differences were not significant. The prevalence of hyperglycaemia was significantly higher in participants with overweight/obese (0.0% vs. 41.6%, phypertension was found. Hyperglycaemia was more prevalent among overweight/obese participants. Copyright © 2014 Diabetes India. Published by Elsevier Ltd. All rights reserved.

    Obesity is not only a health problem but also a source of increased monetary expenditures. The objectives of this study were to analyse the use of healthcare resources in the Spanish adult population with class II obesity and above (BMI ≥35 kg/m 2 ) and to compare it with other BMI groups. We used the Spanish National Health Survey, a longitudinal population-based survey (n = 18,682), to analyse healthcare resource utilisation by BMI groups. Adjusted and unadjusted logistic regression models were used to calculate odds ratios (OR) for healthcare use among class II and over obese subjects versus normal BMI. Persons with BMI ≥35 are more likely to attend general practitioner (GP)'s consultations (17%), to visit the emergency department (26%), to consume medications (36%), to be hospitalised (49%), to require nursing consultations (61%) and to require psychology consultations (83%). The proportion of obese people receiving home visits is 2.6 times higher than among normal BMI. After controlling for sex and age groups, people with severe obesity (BMI ≥35 kg/m 2 ) were more prone to requiring home care visits (OR 2.3; CI [1.3; 4.2]), GP visits (OR 2.1; CI [1.5; 3.0]), psychologist visits (OR 1.96; CI [1.3; 2.99]), emergency service visits (OR 1.5; CI [1.2; 1.8]), nurse visits (OR 1.46; CI [1.2; 1.9]) and hospitalisations (OR 1.43; CI [1.1; 1.9]) and after also adjusting for relevant comorbidities like hypertension, diabetes and cardiovascular diseases: GP visits (OR 1.85; CI [1.3; 2.7]), psychologist visits (OR 1.8; CI [1.2; 2.7]), specialised care visits (OR 0.92; CI [0.7; 1.2]) and physiotherapist visits (OR 0.7; CI [0.5; 1.0]). Severe obesity significantly increases healthcare resource utilisation in Spain. The results shed light on the real magnitude of the burden of obesity in Spain.

    Patients with cardiovascular disease who underwent coronary angiography at the National Institute of Cardiac Surgery and Cardiological Intervention (INCCI) in Luxembourg were surveyed for cardiovascular risk factors (CVRF) (hypertension, hypercholesterolemia, diabetes, obesity, physical inactivity, tobacco consumption). In 2013/14, their life satisfaction (LS) was also assessed. Our aim was to analyse the relationships between LS on one hand and longitudinal changes in CVRF between 2008/09 and 2013/14 and socioeconomic factors on the other. 1289 patients completed a self-administered questionnaire. Life Satisfaction, originally recorded on a 1 to 10 scale of complete satisfaction was dichotomized into two groups: ≤ 7 and. >7. We then performed logistic multiple regressions. The event on which the probability was modelled, was LS > 7. Data were adjusted on age, sex and income. Longitudinal changes in CVRF were assessed by their presence or absence in 2008/09 and 2013/14 (categories: 'no-no'; 'no-yes'; 'yes-no'; 'yes-yes'). Physical activity in 2008/09 and 2013/14 was associated with a lower LS (OR = 0.469). The same pattern was observed for obesity and physical inactivity: lower LS was related to the presence of these risks (yes-yes; no-yes) in 2013/14 (mean OR for obesity and physical inactivity in 2013/14: 0.587 and 0.485 respectively), whereas their presence or absence in 2008/09 was not related to LS. Finally, patients who suffered from diabetes in 2008 were more likely to experience a decline in LS, particularly if their diabetes was less severe in 2013/14 (OR = 0.462). The lowest LS was observed when obesity or physical inactivity was present in 2013/14, newly or otherwise. The same trend was seen in diabetes among patients who had it in 2008/9, but were less severely affected in 2013/14. In secondary prevention, CVD-related upheavals could be minimised if professionals and patients became 'Partners in Healthcare' to better adhere to healthy

  18. Reversal of obesity and insulin resistance by a non-peptidic glucagon-like peptide-1 receptor agonist in diet-induced obese mice.

    Min He

    Full Text Available BACKGROUND: Glucagon-like peptide-1 (GLP-1 is recognized as an important regulator of glucose homeostasis. Efforts to utilize GLP-1 mimetics in the treatment of diabetes have yielded clinical benefits. A major hurdle for an effective oral therapy has been the difficulty of finding a non-peptidic GLP-1 receptor (GLP-1R agonist. While its oral bioavailability still poses significant challenges, Boc5, one of the first such compounds, has demonstrated the attainment of GLP-1R agonism in diabetic mice. The present work was to investigate whether subchronic Boc5 treatment can restore glycemic control and induce sustainable weight loss in diet-induced obese (DIO mice, an animal model of human obesity and insulin resistance. METHODOLOGY/PRINCIPAL FINDINGS: DIO mice were treated three times a week with Boc5 (0.3, 1 and 3 mg for 12 weeks. Body weight, body mass index (BMI, food intake, fasting glucose, intraperitoneal glucose tolerance and insulin induced glucose clearance were monitored regularly throughout the treatment. Glucose-stimulated insulin secretion, β-cell mass, islet size, body composition, serum metabolic profiles, lipogenesis, lipolysis, adipose hypertrophy and lipid deposition in the liver and muscle were also measured after 12 weeks of dosing. Boc5 dose-dependently reduced body weight, BMI and food intake in DIO mice. These changes were associated with significant decreases in fat mass, adipocyte hypertrophy and peripheral tissue lipid accumulation. Boc5 treatment also restored glycemic control through marked improvement of insulin sensitivity and normalization of β-cell mass. Administration of Boc5 (3 mg reduced basal but enhanced insulin-mediated glucose incorporation and noradrenaline-stimulated lipolysis in isolated adipocytes from obese mice. Furthermore, circulating leptin, adiponectin, triglyceride, total cholesterol, nonesterified fatty acid and high-density lipoprotein/low-density lipoprotein ratio were normalized to various

    2017-01-01

    Full Text Available Adipokines are bioactive molecules that regulate several physiological functions such as energy balance, insulin sensitization, appetite regulation, inflammatory response, and vascular homeostasis. They include proinflammatory cytokines such as adipocyte fatty acid binding protein (A-FABP and anti-inflammatory cytokines such as adiponectin, as well as vasodilator and vasoconstrictor molecules. In obesity and type II diabetes mellitus (DM, insulin resistance causes impairment of the endocrine function of the perivascular adipose tissue, an imbalance in the secretion of vasoconstrictor and vasodilator molecules, and an increased production of reactive oxygen species. Recent studies have shown that targeting plasma levels of adipokines or the expression of their receptors can increase insulin sensitivity, improve vascular function, and reduce the risk of cardiovascular morbidity and mortality. Several reviews have discussed the potential of adipokines as therapeutic targets for type II DM and obesity; however, this review is the first to focus on their therapeutic potential for vascular dysfunction in type II DM and obesity.

    Full Text Available Childhood obesity is associated with adult cardiometabolic disease. We postulate that the underlying microvascular dysfunction begins in childhood. We thus aimed to compare retinal vascular parameters between obese and non-obese children.This was a cross-sectional study involving 166 children aged 6 to 12 years old in Malaysia. Ocular examination, biometry, retinal photography, blood pressure and body mass index measurement were performed. Participants were divided into two groups; obese and non-obese. Retinal vascular parameters were measured using validated software.Mean age was 9.58 years. Approximately 51.2% were obese. Obese children had significantly narrower retinal arteriolar caliber (F(1,159 = 6.862, p = 0.010, lower arteriovenous ratio (F(1,159 = 17.412, p < 0.001, higher venular fractal dimension (F(1,159 = 4.313, p = 0.039 and higher venular curvature tortuosity (F(1,158 = 5.166, p = 0.024 than non-obese children, after adjustment for age, gender, blood pressure and axial length.Obese children have abnormal retinal vascular geometry. These findings suggest that childhood obesity is characterized by early microvascular abnormalities that precede development of overt disease. Further research is warranted to determine if these parameters represent viable biomarkers for risk stratification in obesity.

    Despite decades of research, obesity and diabetes remain major health problems in the USA and worldwide. Among the many complications associated with diabetes is an increased risk of cardiovascular diseases, including myocardial infarction and heart failure. Recently, microRNAs have emerged as important players in heart disease and energy regulation. However, little work has investigated the role of microRNAs in cardiac energy regulation. Both human and animal studies have reported a significant increase in circulating free fatty acids and triacylglycerol, increased cardiac reliance on fatty acid oxidation, and subsequent decrease in glucose oxidation which all contributes to insulin resistance and lipotoxicity seen in obesity and diabetes. Importantly, MED13 was initially identified as a negative regulator of lipid accumulation in Drosophilia. Various metabolic genes were downregulated in MED13 transgenic heart, including sterol regulatory element-binding protein. Moreover, miR-33 and miR-122 have recently revealed as key regulators of lipid metabolism. In this review, we will focus on the role of microRNAs in regulation of cardiac and total body energy metabolism. We will also discuss the pharmacological and non-pharmacological interventions that target microRNAs for the treatment of obesity and diabetes.

    The prevalences of obesity and type 2 diabetes mellitus are dramatically increasing, and there is a strong need for more effective and safer therapies. However, some of drugs show limited efficacy and considerable adverse effects. Furthermore, artificial energy-dense foods and non-caloric foods may promote overeating and weight gain. In this context, a natural food-based approach may represent a valuable means of tackling the obesity-diabetes syndrome. Although recent studies have shown that brown rice improves glucose intolerance and prevents obesity and type 2 diabetes in humans, the underlying molecular mechanisms remain unclear. We found that one of the major components of brown rice, γ-oryzanol (Orz), plays an important role in the metabolically beneficial effects of brown rice. Orz acts as a chemical chaperone and decreases high fat diet (HFD)-induced endoplasmic reticulum (ER) stress in the hypothalamus, thereby leading to a significant shift in preference from fatty to healthy foods. Orz also decreases HFD-induced ER stress in pancreatic β-cells and improves β-cell function. Notably, Orz directly acts on pancreatic islets and enhances glucose-stimulated insulin secretion (GSIS). This evidence highlights food preference as a promising therapeutic target in obesity-diabetes syndrome and suggests that brown rice and Orz may have potential for the treatment of obesity and type 2 diabetes in humans. © 2013 Asian Oceanian Association for the Study of Obesity.

    To measure macrophage migration inhibitory factor (MIF) concentrations in obese and non-obese women diagnosed with polycystic ovary syndrome (PCOS). Women diagnosed with PCOS and age-matched healthy controls with regular menses and normal ovaries on ultrasound examination were selected and divided into 4 groups (group A, PCOS and obese; group B, PCOS and non-obese; group C, obese controls; and group D, non-obese controls) based on body mass index (obese >30 kg/m2 and non-obese <25 kg/m2). Luteinizing hormone, follicle-stimulating hormone, androstenedione, testosterone, sex hormone-binding globulin, serum glucose, insulin and MIF levels were measured. Obese and non-obese women with PCOS had higher luteinizing hormone, follicle-stimulating hormone, androstenedione, testosterone, and insulin levels as compared to the obese and non-obese control groups, respectively (P < .0001). Women with PCOS had significantly higher MIF levels (group A, 48.6 ± 9.9 mg/ml; group B, 35.2 ± 6.0 ng/ml) as compared to controls (group C, 13.5 ± 6.0 ng/ml; group D, 12.0 ± 4.3 ng/dl; P < .0001). A weak, positive and significant correlation was seen between fasting blood glucose and insulin levels in women with PCOS (P < .05). Significant differences exist in plasma MIF levels between obese and non-obese women with and without PCOS. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

    BACKGROUND: High dairy/milk intake has been associated with a low risk of type 2 diabetes observationally, but whether this represents a causal association is unknown. OBJECTIVE: We tested the hypothesis that high milk intake is associated with a low risk of type 2 diabetes and of overweight-obesity......, observationally and genetically. DESIGN: In 97,811 individuals from the Danish general population, we examined the risk of incident type 2 diabetes and of overweight-obesity by milk intake observationally and by LCT-13910 C/T genotype [polymorphism (rs4988235) upstream from the lactase (LCT) gene], where TT...... and TC genotypes are associated with lactase persistence and CC with nonpersistence. RESULTS: Observationally for any compared with no milk intake, the HR for type 2 diabetes was 1.10 (95% CI: 0.98, 1.24; P = 0.11), whereas the OR for overweight-obesity was 1.06 (1.02, 1.09; P = 0.002).

    Psoriasis patients have high risk of atherosclerosis, characterized by endothelial dysfunction. We aimed to study the association of the endothelial activation biomarkers monocyte chemoattractant protein 1 (MCP-1), soluble (s) E-selectin and P-selectin with disease activity and severity in psoriasis patients treated with anti-TNF-α therapy. Also, to evaluate the relationship of metabolic syndrome features with these biomarkers and the effect of anti-TNF-α therapy on these molecules. Twenty-nine consecutive non-diabetic patients with moderate-to-severe psoriasis who underwent 6 months of anti-TNF-α-adalimumab therapy were studied. Metabolic and clinical evaluation was performed prior to anti-TNF-α treatment (time 0) and 6 months later. MCP-1, sE-selectin and sP-selectin serum levels were determined by ELISA. Dyslipidemic and obese patients showed higher MCP-1 levels at month 6 from the onset of anti-TNF-α therapy (p = .05 and .01, respectively). sE-selectin positively correlated with pro-inflammatory molecules such as asymmetric dimethylarginine, sP-selectin and resistin at baseline and month 6 (p psoriasis. Adalimumab therapy led to a reduction in sE-selectin levels, supporting the beneficial effect of anti-TNF-α therapy on mechanisms associated with the development of atherosclerosis in psoriasis.

    2017-12-01

    Full Text Available Introduction: Insulin resistance is one of the main cause in the pathogenesis of the development of type- 2 diabetes mellitus. Elevated insulin levels and insulin resistance may be present several years prior to the development of hyperglycaemia. Hence the diagnosis of insulin resistance at the initial stages in risk group people could be used as an effective measure to prevent type 2 diabetes mellitus and its outcome, including reduction in morbidity and mortality. Though type 2 diabetes mellitus has multifactorial aetiology, genetic factor plays an important role in the development of diabetes mellitus. So we have tried to establish relation between genetic factor and insulin resistance by studying the insulin resistance in off springs of diabetics and non diabetics patients. Aims and objectives: Estimation of insulin levels in the off springs (non diabetics of diabetics and non diabetics patients. Comparision of insulin resistance in the off springs (non diabetics of diabetics and non diabetics. To find the relation between insulin resistance and genetic factor. Material and method: This study was carried out in the department of Biochemistry Grant Government Medical College Mumbai. Total 100 non diabetic people were included in the study of age above 30 years. These are divided into two groups as- Group-I includes 50 off springs (Ist degree relatives of non diabetic people. Group-II includes 50 off springs (Ist degree relatives of diabetic people. The fasting plasma glucose and serum insulin levels are estimated in the above two groups. The insulin resistance was calculated by using HOMA-IR model. Result: Fasting plasma glucose, serum insulin level and insulin resistance is significantly increased in group-II people as compared to group-I people. Conclusion: There is a strong relation between genetic factor and insulin resistance which exist prior to the development of diabetes mellitus. The people of group-II are susceptible for the

    Full Text Available Abstract Background The global increased prevalence of obesity and diabetes occurred after the worldwide spread of B-vitamins fortification, in which whether long-term exposure to high level of B vitamins plays a role is unknown. Our aim was to examine the relationships between B-vitamins consumption and the obesity and diabetes prevalence. Methods This population based ecological study was conducted to examine possible associations between the consumption of the B vitamins and macronutrients and the obesity and diabetes prevalence in the US population using the per capita consumption data from the US Economic Research Service and the prevalence data from the US Centers for Disease Control and Prevention. Results The prevalences of diabetes and adult obesity were highly correlated with per capita consumption of niacin, thiamin and riboflavin with a 26-and 10-year lag, respectively (R2 = 0.952, 0.917 and 0.83 for diabetes, respectively, and R2 = 0.964, 0.975 and 0.935 for obesity, respectively. The diabetes prevalence increased with the obesity prevalence with a 16-year lag (R2 = 0.975. The relationships between the diabetes or obesity prevalence and per capita niacin consumption were similar both in different age groups and in male and female populations. The prevalence of adult obesity and diabetes was highly correlated with the grain contribution to niacin (R2 = 0.925 and 0.901, respectively, with a 10-and 26-year lag, respectively. The prevalence of obesity in US adults during 1971-2004 increased in parallel with the increase in carbohydrate consumption with a 10-year lag. The per capita energy and protein consumptions positively correlated with the obesity prevalence with a one-year lag. Moreover, there was an 11-year lag relationship between per capita energy and protein consumption and the consumption of niacin, thiamin and riboflavin (R2 = 0.932, 0.923 and 0.849 for energy, respectively, and R2 = 0.922, 0.878 and 0.787 for protein

    Insulin therapy (IT) is initiated for patients with type 2 diabetes mellitus when glycaemic targets are not met with diet and other hypoglycaemic agents. The initiation of IT improves glycaemic control and reduces the risk of microvascular complications. There is, however, an associated weight gain following IT, which may adversely affect diabetic and cardiovascular morbidity and mortality. A 3 to 9 kg insulin-associated weight gain (IAWG) is reported to occur in the first year of initiating IT, predominantly caused by adipose tissue. The potential causes for this weight gain include an increase in energy intake linked to a fear of hypoglycaemia, a reduction in glycosuria, catch-up weight, and central effects on weight and appetite regulation. Patients with type 2 diabetes who are receiving IT often have multiple co-morbidities, including obesity, that are exacerbated by weight gain, making the management of their diabetes and obesity challenging. There are several treatment strategies for patients with type 2 diabetes, who require IT, that attenuate weight gain, help improve glycaemic control, and help promote body weight homeostasis. This review addresses the effects of insulin initiation and intensification on IAWG, and explores its potential underlying mechanisms, the predictors for this weight gain, and the available treatment options for managing and limiting weight gain. © 2017 John Wiley & Sons Ltd.

    The prevalence of type 2 diabetes is on the increase. Among the other factors, obesity is considered to be a major contributor in the occurrence of type 2 diabetes by disturbing the metabolic regulators of the body. These regulators are certain hormones and peptides produced in the adipocytes and control the intermediary metabolism of the body. These regulators regulate the lipid load up to a certain level and beyond that complication arises. Diabetes mellitus is one of the complications among others. This article reviews the roles and mechanisms of action of these regulators under the influence of lipid load and discusses the factors affecting the rehabilitation of the regulators.

    To determine the geographic distribution of childhood diabetes and obesity relative to the supply of US pediatric endocrinologists. Estimation of observed and "index" ratios of children with diabetes (by region and division) and obesity (body mass index >/=95th % for age and sex) (by region and state) to board-certified pediatric endocrinologists. At the national level, the ratio of children with diabetes to pediatric endocrinologists is 290:1, and the ratio of obese children to pediatric endocrinologists is 17,741:1. Ratios of children with diabetes to pediatric endocrinologists in the Midwest (370:1), South (335:1), and West (367:1) are twice as high as in the Northeast (144:1). Across states, there is up to a 19-fold difference in the observed ratios of obese children to pediatric endocrinologists. Under conditions of equitably distributed endocrinologist supply, variation across states would be mitigated considerably. The distribution of children with diabetes and obesity does not parallel the distribution of pediatric endocrinologists in the United States, due largely to geographic disparities in endocrinologist supply. Given the large burden of obese children to endocrinologists, multidisciplinary models of care delivery are essential for the US health care system to address the needs of children with diabetes and obesity.

    The number of obese women in the childbearing age is drastically increasing globally. As a consequence, more children are born by obese mothers. Unfortunately, maternal obesity and/ or high fat intake during pregnancy increase the risk of developing obesity, type-2 diabetes, cardiovascular disease...... and non-alcoholic fatty liver disease in the children, which passes obesity and metabolic dysfunction on from generation to generation. Several studies try to elucidate causative effects of maternal metabolic markers on the metabolic imprinting in the children; however diet induced obesity is also...... associated with chronic low grade inflammation. Nobody have yet investigated the role of this inflammatory phenotype, but here we demonst rate that obesity induced inflammation is reversed during pregnancy in mice, and is therefore less likely to affect the fetal programming of metabolic dysfunction.

    Metabolic abnormalities have a cumulative effect on development of diabetes, but only central obesity has been defined as the essential criterion of metabolic syndrome (MetS) by the International Diabetes Federation. We hypothesized that central obesity contributes to a higher risk of new-onset diabetes than other metabolic abnormalities in the hypertensive families. Non-diabetic Chinese were enrolled and MetS components were assessed to establish baseline data in a hypertensive family-based cohort study. Based on medical records and glucose tolerance test (OGTT), the cumulative incidence of diabetes was analyzed in this five-year study by Cox regression models. Contribution of central obesity to development of new-onset diabetes was assessed in subjects with the same number of positive MetS components. Among the total of 595 subjects who completed the assessment, 125 (21.0%) developed diabetes. Incidence of diabetes increased in direct proportion to the number of positive MetS components (P ≪ 0.001). Although subjects with central obesity had a higher incidence of diabetes than those without (55.7 vs. 30.0 events/1000 person-years, P ≪ 0.001), the difference became non-significant after adjusting of the number of positive MetS components (hazard ratio = 0.72, 95%CI: 0.45-1.13). Furthermore, in all participants with three positive MetS components, there was no difference in the incidence of diabetes between subjects with and without central obesity (hazard ratio = 1.04, 95%CI: 0.50-2.16). In Chinese hypertensive families, the incidence of diabetes in subjects without central obesity was similar to that in subjects with central obesity when they also had the same number of positive MetS components. We suggest that central obesity is very important, but not the essential component of the metabolic syndrome for predicting of new-onset diabetes. ( NCT00260910, ClinicalTrials.gov).

    Disrupted intermediary metabolism may contribute to the adverse pregnancy outcomes in women with very severe obesity. Our aim was to study metabolism in such pregnancies. We recruited a longitudinal cohort of very severely obese (n = 190) and lean (n = 118) glucose-tolerant women for anthropometric and metabolic measurements at early, mid and late gestation and postpartum. In case-control studies of very severely obese and lean women we measured glucose and glycerol turnover during low- and high-dose hyperinsulinaemic-euglycaemic clamps (HEC) at early and late pregnancy and in non-pregnant women (each n = 6-9) and body fat distribution by MRI in late pregnancy (n = 10/group). Although greater glucose, insulin, NEFA and insulin resistance (HOMA-IR), and greater weight and % fat mass (FM) was observed in very severely obese vs lean participants, the degree of worsening was attenuated in the very severely obese individuals with advancing gestation, with no difference in triacylglycerol (TG) concentrations between very severely obese and lean women at term. Enhanced glycerol production was observed in early pregnancy only in very severely obese individuals, with similar intrahepatic FM in very severely obese vs lean women by late gestation. Offspring from obese mothers were heavier (p = 0.04). Pregnancies complicated by obesity demonstrate attenuation in weight gain and insulin resistance compared with pregnancies in lean women. Increased glycerol production is confined to obese women in early pregnancy and obese and lean individuals have similar intrahepatic FM by term. When targeting maternal metabolism to treat adverse pregnancy outcomes, therapeutic intervention may be most effective applied early in pregnancy.

    This study examined the state of obesity, diabetes, and associated health disparities among understudied multiracial, Native Hawaiian and Other Pacific Islander (NHOPI), and American Indian and Alaskan Native (AIAN) adults. Aggregated data for 184,617 adults from the California Health Interview Survey (2005 to 2011) were analyzed to determine obesity, diabetes, poor/fair health, and physical disability prevalence by racial group. Logistic regressions controlling for age, gender, and key social determinants (education, marital status, poverty, health insurance) generated multiracial, NHOPI, and AIAN adults' odds ratios (ORs) for our targeted health conditions versus non-Hispanic white adults. Obesity, diabetes, and other targeted health conditions were highly prevalent among multiracial, NHOPI, and AIAN adults, who displayed significantly greater adjusted odds than non-Hispanic white adults for obesity (ORs = 1.2-1.9), diabetes (ORs = 1.6-2.4), poor/fair health (ORs = 1.4-1.7), and, with the exception of NHOPI adults, physical disability (ORs = 1.5-1.6). Multiracial and AIAN adults with obesity also had significantly higher adjusted odds of diabetes (OR = 1.5-2.6) than non-Hispanic white adults with obesity. Multiracial, NHOPI, and AIAN adults experience striking obesity-related disparities versus non-Hispanic white adults, urging further disparities research with these vulnerable minority populations. © 2017 The Obesity Society.

    Obesity and its associated complications like type 2 diabetes (T2D) are reaching epidemic stages. Increased food intake and lack of exercise are two main contributing factors. Recent work has been highlighting an increasingly more important role of gut microbiota in metabolic disorders. It's well known that gut microbiota plays a major role in the development of food absorption and low grade inflammation, two key processes in obesity and diabetes. This review summarizes key discoveries during the past decade that established the role of gut microbiota in the development of obesity and diabetes. It will look at the role of key metabolites mainly the short chain fatty acids (SCFA) that are produced by gut microbiota and how they impact key metabolic pathways such as insulin signalling, incretin production as well as inflammation. It will further look at the possible ways to harness the beneficial aspects of the gut microbiota to combat these metabolic disorders and reduce their impact.

    2013-01-01

    Full Text Available Macrophage migration inhibitory factor (MIF is implicated in the pathogenesis of several inflammationrelated diseases, including obesity and type 2 diabetes (T2D. However, MIF deficiency itself promotes obesity and glucose intolerance in mice. Here we show that the introduction of a high-fat diet (HFD further aggravates the parameters of obesity-associated T2D: weight gain and glucose intolerance. Furthermore, in contrast to MIF-KO mice on standard chow, HFD-fed MIF-KO mice develop insulin resistance. Although the clinical signs of obesity-associated T2D are upgraded, inflammation in MIF-deficient mice on HFD is significantly lower. These results imply that MIF possesses a complex role in glucose metabolism and the development of obesity-related T2D. However, the downregulation of inflammation upon MIF inhibition could be a useful tool in short-term T2D therapy for preventing pancreatic islet deterioration.

    Evidence has been accumulating on the importance of the rising burden of diabetes mellitus on the African continent at an increasingly higher pace. In the first paper of this series of two companion papers, recent evidence on the prevalence, pathogenesis and comorbidities of obesity and diabetes mellitus in Africa were summarised. In this second paper, we focus on recent developments pertaining to the prevention, screening and the economic burden of diabetes and obesity on the continent. There are indications that awareness on diabetes and chronic diseases at large has increased in Africa in recent times. However, the care for diabetes largely remains suboptimal in most countries, which are not adequately prepared to face the prevention and control of diabetes, as the costs of caring for the condition pose a tremendous challenge to most local economies. Moreover, translation strategies to prevent and control diabetes and obesity, on the continent, are still to be evaluated.

    Shoulder dystocia remains an obstetric emergency. Maternal diabetes is considered to be one of the major risk factors for shoulder dystocia. The aim of this study was to analyze antepartum and peripartum risk factors and complications of shoulder dystocia in diabetic and non-diabetic women. We performed a retrospective analysis of 48 shoulder dystocia cases out of 28,485 vaginal deliveries of singleton, live-born infants over a 13 year period: 13 cases were diagnosed in diabetic women and 35 cases in non-diabetic women. The study was conducted in the 2nd Department of Obstetrics and Gynecology, Medical University of Warsaw, Poland, from January 2000 to December 2012. Compared to non-diabetic women, diabetic patients had significantly higher pre-pregnancy body weight (83.4±23.8 kg vs. 62.5±10.9 kg, p=0.002), higher pre-pregnancy BMI (30.2±6.8 kg/m2 vs. 22.9±4.3 kg/m2, p=0.0003), and lower gestational weight gain (11.4±6.2 kg vs. 16.0±4.7 kg, p=0.01). Diabetic women with shoulder dystocia were more likely to deliver before completion of the 38th week of gestation (30.8% vs. 5.7%, p=0.02) and had a higher incidence of 1st and 2nd stage perineal tears compared with the non-diabetic group (23.1% vs. 0%, p=0.02). There were two cases of symphysis pubis dehiscence in non-diabetic women. Children of diabetic mothers had a significantly higher birth weight (4,425.4±561.6 g vs. 4,006.9±452.8 g, p=0.03). Children of diabetic mothers with dystocia were at significantly higher risk of peripartum injuries (92.3% vs. 45.7%). A significant difference was observed in the percentage of brachial plexus palsy (61.5% vs. 17.1%). Children of diabetic women experiencing shoulder dystocia were more frequently affected by Erb's brachial plexus palsy and respiratory disturbances. These children had an increased likelihood of birth weights above the 90th percentile (not necessarily reaching 4,000 g) compared to children born to non-diabetic mothers.

    To assess whether partial-mouth protocols (PRPs) result in biased estimates of the associations between smoking, alcohol, obesity and diabetes with periodontitis. Using a sample (n = 6129) of the 1996-1998 Atherosclerosis Risk in Communities study, we used measures of probing pocket depth and clinical attachment level to identify moderate-severe periodontitis. Adjusting for confounders, unconditional binary logistic regression estimated prevalence odds ratios (POR) and 95% confidence limits. Specifically, we compared POR for smoking, alcohol, obesity and diabetes with periodontitis derived from full-mouth to those derived from 4-PRPs (Ramfjörd, National Health and Nutrition Examination survey-III, modified-NHANES-IV and 42-site-Random-site selection-method). Finally, we conducted a simple sensitivity analysis of periodontitis misclassification by changing the case definition threshold for each PRP. In comparison to full-mouth PORs, PRP PORs were biased in terms of magnitude and direction. Holding the full-mouth case definition at moderate-severe periodontitis and setting it at mild-moderate-severe for the PRPs did not consistently produce POR estimates that were either biased towards or away from the null in comparison to full-mouth estimates. Partial-mouth protocols result in misclassification of periodontitis and may bias epidemiologic measures of association. The magnitude and direction of this bias depends on choice of PRP and case definition threshold used. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The role of incretins in type 2 diabetes is controversial. This study investigated the association between incretin levels in obese Korean children and adolescents newly diagnosed with type 2 diabetes. We performed a 2-hr oral glucose tolerance test (OGTT) in obese children and adolescents with type 2 diabetes and with normal glucose tolerance. Twelve obese children and adolescents with newly diagnosed type 2 diabetes (DM group) and 12 obese age-matched subjects without type 2 diabetes (NDM group) were included. An OGTT was conducted and insulin, C-peptide, glucagon, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) were measured during the OGTT. The mean age of the patients was 13·8 ± 2·0 years, and the mean body mass index (BMI) Z-score was 2·1 ± 0·5. The groups were comparable in age, sex, BMI Z-score and waist:hip ratio. The DM group had significantly lower homeostasis model assessment of β and insulinogenic index values (P 1). The homeostasis model assessment of insulin resistance index was not different between the two groups. Insulin and C-peptide secretions were significantly lower in the DM group than in the NDM group (P 1). Total GLP-1 secretion was significantly higher in the DM group while intact GLP-1 and GIP secretion values were not significantly different between the two groups. Impaired insulin secretion might be important in the pathogenesis of type 2 diabetes in obese Korean children and adolescents, however, which may not be attributed to incretin secretion. © 2015 John Wiley & Sons Ltd.

    Non alcoholic fatty liver disease (NAFLD, the hepatic fat accumulation) and non alcoholic steatohepatitis (NASH, the aggressive form of liver steatosis plus inflammation and hepatocyte necrosis) are reaching epidemic dimensions in subjects with diabetes mellitus (DM). Taking into account that the incidence of DM increases worldwide, these entities represent major health problems. There is accumulating evidence that diabetic subjects with NASH are at increased risk not only for cardiovascular disease compications but also for cirrhosis and hepatocellular cancer. On the other hand, the presence of NAFLD correlates with an increased risk for the development of DM. The most-widely accepted pathophysiological mechanisms relating DM and NAFLD include central obesity and insulin resistanc, but new insights are under scrutiny. Therapeutic modalities used for the management of diabetes have been studied for their impact on NAFLD/NASH and both neutral and beneficial effects have been reported. In this review, we discuss issues regarding the epidemiology, the pathophysiological pathways relating NAFLD with DM and consider strategies that may be useful in the management of NAFLD in the diabetic population.

    Since low basal metabolic rate (BMR) is a risk factor for weight regain, it is important to measure BMR before bariatric surgery. We aimed to evaluate the BMR among clinically severe obese patients preoperatively. We compared it with that of the control group, with predictive formulas and correlated it with body composition. We used indirect calorimetry (IC) to collect BMR data and multifrequency bioelectrical impedance to collect body composition data. Our sample population consisted of 193 patients of whom 130 were clinically severe obese and 63 were normal/overweight individuals. BMR results were compared with the following predictive formulas: Harris-Benedict (HBE), Bobbioni-Harsch (BH), Cunningham (CUN), Mifflin-St. Jeor (MSJE), and Horie-Waitzberg & Gonzalez (HW & G). This study was approved by the Ethics Committee for Research of the University of Brasilia. Statistical analysis was used to compare and correlate variables. Clinically severe obese patients had higher absolute BMR values and lower adjusted BMR values (p BMR were found in both groups. Among the clinically severe obese patients, the formulas of HW & G and HBE overestimated BMR values (p = 0.0002 and p = 0.0193, respectively), while the BH and CUN underestimated this value; only the MSJE formulas showed similar results to those of IC. The clinically severe obese patients showed low BMR levels when adjusted per kilogram per body weight. Body composition may influence BMR. The use of the MSJE formula may be helpful in those cases where it is impossible to use IC.

    Full Text Available Background. This study was carried out to establish the prevalence of cardiovascular risks such as hypertension, obesity, and diabetes in Eastern Nepal. This study also establishes the prevalence of metabolic syndrome (MS and its relationships to these cardiovascular risk factors and lifestyle. Methods. 14,425 subjects aged 20–100 (mean 41.4 ± 15.1 were screened with a physical examination and blood tests. Both the International Diabetic Federation (IDF and National Cholesterol Education Programme’s (NCEP definitions for MS were used and compared. Results. 34% of the participants had hypertension, and 6.3% were diabetic. 28% were overweight, and 32% were obese. 22.5% of the participants had metabolic syndrome based on IDF criteria and 20.7% according to the NCEP definition. Prevalence was higher in the less educated, people working at home, and females. There was no significant correlation between the participants’ lifestyle factors and the prevalence of MS. Conclusion. The high incidence of dyslipidemia and abdominal obesity could be the major contributors to MS in Nepal. Education also appears to be related to the prevalence of MS. This study confirms the need to initiate appropriate treatment options for a condition which is highly prevalent in Eastern Nepal.

Objectives To investigate the association of maternal hyperglycemia exposure during pregnancy with obesity and abnormal glucose tolerance in offspring, and the age at occurrence. Methods We searched MEDLINE and EMBASE for observational studies on obesity and diabetes in offspring of diabetic mothers (gestational diabetes mellitus (GDM), type 1 diabetes mellitus (T1DM) and T2DM), and those on non-diabetic mothers. We performed fixed effect meta-analysis for all studies except when heterogeneity was detected. The quality of studies was evaluated using the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS) Results Twenty observational studies were included involving a total of 26,509 children.

    Understanding the determinants of human health and disease is overwhelmingly complex, particularly for common, late-onset, chronic disorders, such as obesity and diabetes. Elucidating the genetic and environmental factors that influence susceptibility to disruptions in energy homeostasis and metabolic regulation remain a challenge, and progress will entail the integration of multiple assessments of temporally dynamic environmental exposures in the context of each individual's genotype. To meet this challenge, researchers are increasingly exploring the epigenome, which is the malleable interface of gene-environment interactions. Epigenetic variation, whether innate or induced, contributes to variation in gene expression, the range of potential individual responses to internal and external cues, and risk for metabolic disease. Ultimately, advancement in our understanding of chronic disease susceptibility in humans will depend on refinement of exposure assessment tools and systems biology approaches to interpretation. In this review, we present recent progress in epigenetics of human obesity and diabetes, existing challenges, and the potential for new approaches to unravel the complex biology of metabolic dysregulation.

    Type 2 diabetes is associated with many comorbid medical conditions including obesity, neuropathy, microvascular pathology and atherosclerotic arterial disease. Due to its complications and chronicity, reducing risk factors such as obesity and sedentary lifestyle through lifestyle modification is crucial to the long-term health of patients with type 2 diabetes. Patients must learn how to adopt lifelong, low-fat eating habits and regular activity patterns, with formal treatments focusing on weight loss, increased physical activity and low-fat, low-saturated fat diets. In this article we review the efficacy of lifestyle modification programmes for obese diabetic patients. In addition, we discuss barriers to lifestyle changes and methods for improving long-term adherence. Finally, we present information on how this approach has been adapted to a group of Mexican Americans in the USA, a population at high risk for type 2 diabetes, obesity and sedentary lifestyle.

    Clinical parameters, androgen status and lipoprotein lipid profiles were assessed in 10 non-obese and 10 obese patients with polycystic ovarian disease (PCOD) and reference subjects matched for age, height and weight. Both obese and non-obese women with PCOD had significantly higher androgen levels when compared to the reference groups. When comparison of lipoprotein lipid profiles were made between groups, non-obese women with PCOD had significantly higher total cholesterol, triglycerides and LDL-cholesterol levels than non-obese reference subjects. Obese PCOD women manifested significantly higher total cholesterol, LDL-cholesterol, cholesterol/HDL, and LDL/HDL values than did obese reference subjects. Correlations between serum androgens and lipoprotein lipid concentrations in PCOD and normal women were unhelpful. Both non-obese and obese patients with PCOD had significantly higher systolic and diastolic blood pressures (BPs) than the reference groups. Thus, both non-obese and obese women with PCOD manifest hyperandrogenaemia which may result in a male pattern of lipoprotein lipid concentrations.

    Obstructive sleep apnoea (OSA) may independently increase cardiovascular risk in obesity. Although there is evidence that arterial stiffness is altered in OSA, knowledge of these effects with continuous positive airway pressure (CPAP) in severe obesity (body mass index (BMI) ≥ 35 kg/m(2)) is limited. This study aimed to explore how arterial stiffness, as measured by the augmentation index (Aix), changed in severely obese patients with OSA who were treated with CPAP and in patients without OSA. Forty-two patients with severe obesity-22 with OSA, 20 without OSA-were recruited at baseline and followed-up after a median of 13.5 months. Pulse wave analysis (PWA) was performed using applanation tonometry at the radial artery to measure augmentation index (Aix), augmentation pressure (AP) and subendocardial viability ratio (SEVR). Cardiovascular parameters and body composition were also measured. There were significant improvements in Aix, AP (both P CPAP compared with subjects without OSA. Epworth scores (P CPAP. Regression showed that CPAP was significantly associated with change in arterial stiffness from baseline. However, patients with OSA on CPAP continued to have increased arterial stiffness (Aix) (P CPAP in severe obesity, CPAP alone is not sufficient to modify PWA measures to levels comparable with non-OSA patients. This supports a need for a multifaceted approach when managing cardiovascular risk in patients with severe obesity and obstructive sleep apnoea receiving CPAP therapy.

    Background: Globally, obesity is now recognised as an epidemic. The degree of obesity is proportional to the rate of development of cardiovascular diseases, hence, resulting in a dramatic increase in morbidity and mortality. Apart from obesity, hypertension is another well recognised risk factor contributing to coronary artery disease (CAD). The precise prevalence of obesity-related hypertension varies with age, race and gender; and is yet unknown in our population. The objective of this study was to determine the prevalence of hypertension in obese and non-obese patients with diagnosed CAD. Methods: This hospital based descriptive study was conducted in Cardiology Department of Postgraduate Medical Institute, Lady Reading Hospital, Peshawar from March 15, 2007 to May 30, 2008. A total of 200 patients with diagnosed CAD were enrolled, 100 were found obese and 100 non-obese. Results: Among these, a total of 111 (55.5%) were found to be hypertensive, 66 (59.46%) of these were obese and 45 (40.54%) non-obese (p=0.003). Conclusion: Obese patients with CAD had significantly more frequent hypertension. (author)

    We aimed to compare the risks of severe asphyxia-related neonatal complications in the offspring of mothers with type 1 or type 2 diabetes, and to assess the impact of maternal overweight/obesity on these risks. This was a population-based study of 1,343,751 live-born singleton infants in Sweden between 1997 and 2011, including 5941 and 711 infants of mothers with type 1 and type 2 diabetes, respectively. ORs with 95% CIs were calculated for low Apgar score (0-6) at 5 min after birth, hypoxic ischaemic encephalopathy and neonatal seizures. The rates of a low Apgar score were 0.9%, 2.6% and 2.1% in the offspring of mothers without diabetes or with type 1 or type 2 diabetes, respectively. After controlling for maternal confounders (including BMI), the risk of a low Apgar score increased in the offspring of mothers with type 1 diabetes (OR 2.67, 95% CI 2.23, 3.20) but not in the offspring of mothers with type 2 diabetes (OR 1.25, 95% CI 0.66, 2.35). The ORs of hypoxic ischaemic encephalopathy or neonatal seizures were increased in the offspring of mothers with type 1 diabetes (OR 3.41, 95% CI 2.58, 4.49) and type 2 diabetes (OR 2.54, 95% CI 1.13, 5.69). Maternal overweight/obesity was a risk factor for asphyxia-related neonatal complications and low Apgar scores in the offspring of mothers with type 1 diabetes and mothers without diabetes. The risks of a low Apgar score and severe asphyxia-related neonatal complications are increased in the offspring of mothers with type 1 or type 2 diabetes. Maternal overweight/obesity is an important contributing factor.

    weight status and suPAR were tested. During a 3-year follow-up (599 incident diabetes cases), there was a 48% overall increase in the odds of developing type 2 diabetes per twofold increase in suPAR (p = 0.006). This association was modified by body weight status in overweight, but not in obese...... among overweight participants. suPAR may be a good novel biomarker for systemic sub-clinical inflammation and immune activation linked to incident type 2 diabetes risk in overweight individuals and non-smokers. The observed interactions with adiposity and smoking should be investigated further.......Recent evidence links the soluble urokinase plasminogen activator receptor (suPAR), a stable biomarker of systemic immune activation, to several chronic diseases, including type 2 diabetes. suPAR is also associated with adiposity and smoking. We hypothesised that this biomarker would be linked...

  10. Morbidity of severe obesity.

    Although obesity is an easy diagnosis to make, its etiologies, pathophysiology, and symptomatology are extraordinarily complex. Progress in surgical technique and anesthesiological management has substantially improved the safety of performing operations on the severely obese in the last 20 years. These improvements have occurred more or less empirically, without a full understanding of etiology or pathophysiology, although this has advanced concomitantly with improvements in practice. This review has attempted to provide a framework to facilitate progress in the neglected areas of patient selection and choice of operation, in an effort to improve long-term outcome. Despite the disparate etiologies of obesity and its diverse comorbidities and complications, there are unifying interdependent pathogenetic mechanisms of great relevance to the practice of antiobesity surgery. The rate of eating, whether driven by HPA dysfunction, ambient stress, or related hereditary susceptibility factors including the increased energy demands of an expanded body fat mass, participates in a cycle that results in disordered satiety (see Fig. 3). This leads to substrate overload, causing extensive metabolic abnormalities such as atherogenesis, insulin resistance, thrombogenesis, and carcinogenesis. This interpretation of the pathophysiology of obesity ironically accords with the original meaning of the word obesity: "to overeat." The ultimate solution to the problem of obesity--preventing it--will not be forthcoming until the food industry is forced to lower production and change its marketing strategies, as the liquor and tobacco industries in the United States were compelled to do. This cannot occur until the large and fast-growing populations of industrialized nations become educated in the personal implications of the energy principle. Regardless of whether school curricula are modified to prioritize health education, the larger problems of cultural and economic change remain for

    To explore the relationship between severity of obesity at age 7 and age 15, age at onset of obesity, and parental body mass index (BMI) in obese children and adolescents. Longitudinal cohort study. Obese children (n = 231) and their parents (n = 462) from the Swedish National Childhood Obesity Centre. Multivariate regression analyses were applied with severity of obesity (BMI standard deviation score (BMI SDS)) and onset of obesity as dependent variables. The effect of parental BMI was evaluated and in the final models adjusted for gender, parental education, age at onset of obesity, severity of obesity at age 7 and obesity treatment. For severity of obesity at age 7, a positive correlation with maternal BMI was indicated (P = 0.05). Severity of obesity at this age also showed a strong negative correlation with the age at onset of obesity. Severity of obesity at age 15 was significantly correlated with both maternal and paternal BMI (P obesity at age 7 and negatively correlated with treatment. Also, a negative correlation was indicated at this age for parental education. No correlation with age at onset was found at age 15. For age at onset of obesity there was no relevant correlation with parental BMI. Children within the highest tertile of the BMI SDS range were more likely to have two obese parents. The impact of parental BMI on the severity of obesity in children is strengthened as the child grows into adolescence, whereas the age at onset is probably of less importance than previously thought. The influence of parental relative weight primarily affects the severity of childhood obesity and not the timing.

    Objective: To determine insulin resistance and beta cell function in healthy obese and nonobese individuals of the local population. Study Design: Case control study. Place and Duration of Study: AFIP Rawalpindi in collaboration with department of medicine military hospital(MH) Rawalpindi, from Aug 2008 to Mar 2009. Methods: Eighty obese(n=40) and non-obese(n=40) subjects were selected by non-probability convenience sampling. Plasma insulin, glucose, and serum total cholestrol were estimated in fasting state. Insulin resistance was calculated by HOMA-IR and beta cell function by HOMA- equation. Results: Significant differences were observed between obese and non-obese individuals regarding insulin resistance, beta cell function, and BMI and serum total cholesterol. Mean insulin resistance in obese group was found to be 11.1 +- 5.1(range 7.0-16.2) and in non-obese group it was 0.9+-0.4 (range 0.5-1.3). This difference was highly significant (p=0.001). There was a highly significant difference between the two groups in term of beta cell function with mean rank 60.1 for obese group and 20.9 non obese groups (Asym sig. 2 tailed 0.000). Also the correlation (r = 0.064) between insulin resistance and beta cell function in obese group is highly significant (p = 0.000). Mean serum leptin levels were lower (6.3 ng/ml) in non-obese, and high (57.2 ng/ml) in the obese group. Conclusions: Insulin resistance is found higher in obese individuals. Beta cell function is significantly different between obese and non-obese groups. (author)

    This study primarily aimed to investigate the short- and long-term remission rates of type 2 diabetes (T2D) in patients who underwent surgical treatment for gastric cancer, especially patients who were non-obese, and secondarily to determine the potential factors associated with remission. We retrospectively reviewed the clinical records of patients with T2D who underwent radical gastrectomy for gastric cancer, from January 2008 to December 2012. T2D improved in 39 out of 70 (55.7%) patients at the postoperative 2-year follow-up and 21 of 42 (50.0%) at the 5-year follow-up. In the 2-year data analysis, preoperative body mass index (BMI) (P=0.043), glycated hemoglobin (A1C) level (P=0.039), number of anti-diabetic medications at baseline (P=0.040), reconstruction method (statistical difference was noted between Roux-en-Y reconstruction and Billroth I; P=0.035) were significantly related to the improvement in glycemic control. Unlike the results at 2 years, the 5-year data analysis revealed that only preoperative BMI (P=0.043) and A1C level (P=0.039) were statistically significant for the improvement in glycemic control; however, the reconstruction method was not. All types of gastric cancer surgery can be effective in short- and long-term T2D control in non-obese patients. In addition, unless long-limb bypass is considered in gastric cancer surgery, the long-term glycemic control is not expected to be different between the reconstruction methods.

    To determine risk for type 2 diabetes in subjects with fasting glucose levels in the ranges of normoglycemia, mild hyperglycemia, and intermediate hyperglycemia and to assess the effect of obesity and metabolic syndrome on this risk. Incidence of type 2 diabetes mellitus was evaluated in 28,209 relatively healthy subjects participating in the Cooper Center Longitudinal Study. They were included in the study if they had more than 1 fasting plasma glucose measurement, anthropometry, and other parameters of interest. Three subgroups were identified: normoglycemic (obesity, and metabolic syndrome status. Incident diabetes was assessed at the earliest clinic visit at which the individual exhibited a blood glucose level of more than 7.0 mmol/L or reported a diagnosis of diabetes. Thirty-one percent of men and 15.9% of women had mild hyperglycemia and 11.9% of men and 3.6% of women had intermediate hyperglycemia. Yearly conversion rates to diabetes were low in individuals with normoglycemia and mild hyperglycemia but were strikingly higher in those with intermediate hyperglycemia. In subjects with intermediate hyperglycemia, presence of obesity and/or metabolic syndrome doubled conversion rates to diabetes. This study showed a marked difference in outcomes in subjects with mild and intermediate hyperglycemia. Moreover, obesity and metabolic syndrome were associated with strikingly elevated risk for diabetes in subjects with intermediate hyperglycemia. Thus intermediate hyperglycemia plus obesity/metabolic syndrome seemingly justifies intensive clinical intervention for prevention of both diabetes and cardiovascular disease.

    2015-01-01

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is a highly prevalent disorder associated with obesity and metabolic syndrome. The main pathophysiological factor of liver steatosis is insulin resistance that may lead to development of type 2 diabetes mellitus. Overcoming of insulin resistance by means of body weight reduction and administration of insulin sensitizers is considered to be a promising approach to NAFLD treatment. In accordance with the Russian guidelines on diagnostics and treatment of NAFLD, sibutramine is the drug of choice for medical treatment of obesity. As for insulin sensitizers, metformin (biguanide class is widely used for treatment of NAFLD in everyday clinical practice. Treatment of NAFLD as a component of metabolic syndrome should be multifactorial and aimed at different aspects of the disease pathophysiology.

    Although type 1 diabetes (T1D) is a T-cell-mediated disease in the effector stage, the mechanism behind the initial beta cell assault is less understood. Metabolomic differences, including elevated levels of glutamic acid, have been observed in patients with T1D before disease onset, as well as in pre-diabetic non-obese diabetic (NOD) mice. Increased levels of glutamic acid damage both neurons and beta cells, implying that this could contribute to the initial events of T1D pathogenesis. We investigated the underlying genetic factors and consequences of the increased levels of glutamic acid in NOD mice. Serum glutamic acid levels from a (NOD×B6)F 2 cohort (n = 182) were measured. By genome-wide and Idd region targeted microsatellite mapping, genetic association was detected for six regions including Idd2, Idd4 and Idd22. In silico analysis of potential enzymes and transporters located in and around the mapped regions that are involved in glutamic acid metabolism consisted of alanine aminotransferase, glutamic-oxaloacetic transaminase, aldehyde dehydrogenase 18 family, alutamyl-prolyl-tRNA synthetase, glutamic acid transporters GLAST and EAAC1. Increased EAAC1 protein expression was observed in lysates from livers of NOD mice compared with B6 mice. Functional consequence of the elevated glutamic acid level in NOD mice was tested by culturing NOD. Rag2 -/- Langerhans' islets with glutamic acid. Induction of apoptosis of the islets was detected upon glutamic acid challenge using TUNEL assay. Our results support the notion that a dysregulated metabolome could contribute to the initiation of T1D. We suggest that targeting of the increased glutamic acid in pre-diabetic patients could be used as a potential therapy. © 2016 John Wiley & Sons Ltd.

    Full Text Available PurposeObesity is a major modifiable risk factor for cardiovascular disease. Bariatric surgery is considered to be the most effective treatment option for weight reduction in obese patients with and without type 2 diabetes (T2DM.ObjectiveTo evaluate changes in lipoproteins, insulin resistance, mediators of systemic and vascular inflammation, and endothelial dysfunction following Roux-en-Y bariatric surgery in obese patients with and without diabetes.Materials and methodsLipoproteins, insulin resistance, mediators of systemic and vascular inflammation, and endothelial dysfunction were measured in 37 obese patients with (n = 17 and without (n = 20 T2DM, before and 6 and 12 months after Roux-en-Y bariatric surgery. Two way between subject ANOVA was carried out to study the interaction between independent variables (time since surgery and presence of diabetes and all dependent variables.ResultsThere was a significant effect of time since surgery on (large effect size weight, body mass index (BMI, waist circumference, triglycerides (TG, small-dense LDL apolipoprotein B (sdLDL ApoB, HOMA-IR, CRP, MCP-1, ICAM-1, E-selectin, P-selectin, leptin, and adiponectin. BMI and waist circumference had the largest impact of time since surgery. The effect of time since surgery was noticed mostly in the first 6 months. Absence of diabetes led to a significantly greater reduction in total cholesterol, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol although the effect size was small to medium. There was a greater reduction in TG and HOMA-IR in patients with diabetes with a small effect size. No patients were lost to follow up.ConclusionLipoproteins, insulin resistance, mediators of systemic and vascular inflammation, and endothelial dysfunction improve mostly 6 months after bariatric surgery in obese patients with and without diabetes.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier: NCT02169518. https

    People with severe mental illnesses, such as schizophrenia, depression or bipolar disorder, have worse physical health and reduced life expectancy compared to the general population. The excess cardiovascular mortality associated with schizophrenia and bipolar disorder is attributed in part to an increased risk of the modifiable coronary heart disease risk factors; obesity, smoking, diabetes, hypertension and dyslipidaemia. Antipsychotic medication and possibly other psychotropic medication like antidepressants can induce weight gain or worsen other metabolic cardiovascular risk factors. Patients may have limited access to general healthcare with less opportunity for cardiovascular risk screening and prevention than would be expected in a non-psychiatric population. The European Psychiatric Association (EPA), supported by the European Association for the Study of Diabetes (EASD) and the European Society of Cardiology (ESC) published this statement with the aim of improving the care of patients suffering from severe mental illness. The intention is to initiate cooperation and shared care between the different healthcare professionals and to increase the awareness of psychiatrists and primary care physicians caring for patients with severe mental illness to screen and treat cardiovascular risk factors and diabetes.

    Obesity and diabetes are epidemic in the European Union (EU). Exposure to endocrine-disrupting chemicals (EDCs) is increasingly recognized as a contributor, independent of diet and physical activity. The objective was to estimate obesity, diabetes, and associated costs that can be reasonably attributed to EDC exposures in the EU. An expert panel evaluated evidence for probability of causation using weight-of-evidence characterization adapted from that applied by the Intergovernmental Panel on Climate Change. Exposure-response relationships and reference levels were evaluated for relevant EDCs, and biomarker data were organized from peer-reviewed studies to represent European exposure and burden of disease. Cost estimation as of 2010 utilized published cost estimates for childhood obesity, adult obesity, and adult diabetes. Setting, Patients and Participants, and Intervention: Cost estimation was performed from the societal perspective. The panel identified a 40% to 69% probability of dichlorodiphenyldichloroethylene causing 1555 cases of overweight at age 10 (sensitivity analysis: 1555-5463) in 2010 with associated costs of €24.6 million (sensitivity analysis: €24.6-86.4 million). A 20% to 39% probability was identified for dichlorodiphenyldichloroethylene causing 28 200 cases of adult diabetes (sensitivity analysis: 28 200-56 400) with associated costs of €835 million (sensitivity analysis: €835 million-16.6 billion). The panel also identified a 40% to 69% probability of phthalate exposure causing 53 900 cases of obesity in older women and €15.6 billion in associated costs. Phthalate exposure was also found to have a 40% to 69% probability of causing 20 500 new-onset cases of diabetes in older women with €607 million in associated costs. Prenatal bisphenol A exposure was identified to have a 20% to 69% probability of causing 42 400 cases of childhood obesity, with associated lifetime costs of €1.54 billion. EDC exposures in the EU contribute

    Full Text Available All obese women are categorised as being of equally high risk of gestational diabetes (GDM whereas the majority do not develop the disorder. Lifestyle and pharmacological interventions in unselected obese pregnant women have been unsuccessful in preventing GDM. Our aim was to develop a prediction tool for early identification of obese women at high risk of GDM to facilitate targeted interventions in those most likely to benefit. Clinical and anthropometric data and non-fasting blood samples were obtained at 15+0-18+6 weeks' gestation in 1303 obese pregnant women from UPBEAT, a randomised controlled trial of a behavioural intervention. Twenty one candidate biomarkers associated with insulin resistance, and a targeted nuclear magnetic resonance (NMR metabolome were measured. Prediction models were constructed using stepwise logistic regression. Twenty six percent of women (n = 337 developed GDM (International Association of Diabetes and Pregnancy Study Groups criteria. A model based on clinical and anthropometric variables (age, previous GDM, family history of type 2 diabetes, systolic blood pressure, sum of skinfold thicknesses, waist:height and neck:thigh ratios provided an area under the curve of 0.71 (95%CI 0.68-0.74. This increased to 0.77 (95%CI 0.73-0.80 with addition of candidate biomarkers (random glucose, haemoglobin A1c (HbA1c, fructosamine, adiponectin, sex hormone binding globulin, triglycerides, but was not improved by addition of NMR metabolites (0.77; 95%CI 0.74-0.81. Clinically translatable models for GDM prediction including readily measurable variables e.g. mid-arm circumference, age, systolic blood pressure, HbA1c and adiponectin are described. Using a ≥35% risk threshold, all models identified a group of high risk obese women of whom approximately 50% (positive predictive value later developed GDM, with a negative predictive value of 80%. Tools for early pregnancy identification of obese women at risk of GDM are described

    Clinical symptoms of diabetic nephropathy patients and non-diabetic nephropathy are compared and analyzed, hemodialysis effect and quality of life of two kinds of nephrotic patients are analyzed. Respectively extract 1300 cases of diabetic nephropathy and non-diabetic nephropathy patients admitted to different hospitals during December 2011-December 2014. Based on whether the patient suffers from diabetes, they were divided into diabetic group and control group. Hemodialysis of two groups of patients were followed up to observe effectiveness of blood treatment, and complications were observed after one year of follow-up. Hematodialysis effectiveness of diabetic nephropathy patients is significantly lower than that of non-diabetic nephropathy group. After 1 year's follow-up, it can be found that survival rate of diabetic nephropathy patients is much lower than that of control group. In statistical comparison of data involved in the two groups of patients, P diabetic nephropathy patients is relatively poor compared to that of non-diabetic patients. In clinics, management and prevention of diabetic patients should be strengthened to avoid complication of nephropathy which brings serious injury to patients.

    Metabolic syndrome is associated with alterations in the structure of the gut microbiota leading to low-grade inflammatory responses. An increased penetration of the impaired gut membrane by bacterial components is believed to induce this inflammation, possibly involving epigenetic alteration of inflammatory molecules such as Toll-like receptors (TLRs). We evaluated changes of the gut microbiota and epigenetic DNA methylation of TLR2 and TLR4 in three groups of subjects: type 2 diabetics under glucagon-like peptide-1 agonist therapy, obese individuals without established insulin resistance, and a lean control group. Clostridium cluster IV, Clostridium cluster XIVa, lactic acid bacteria, Faecalibacterium prausnitzii and Bacteroidetes abundances were analysed by PCR and 454 high-throughput sequencing. The epigenetic methylation in the regulatory region of TLR4 and TLR2 was analysed using bisulfite conversion and pyrosequencing. We observed a significantly higher ratio of Firmicutes/ Bacteroidetes in type 2 diabetics compared to lean controls and obese. Major differences were shown in lactic acid bacteria, with the highest abundance in type 2 diabetics, followed by obese and lean participants. In comparison, F. prausnitzii was least abundant in type 2 diabetics, and most abundant in lean controls. Methylation analysis of four CpGs in the first exon of TLR4 showed significantly lower methylation in obese individuals, but no significant difference between type 2 diabetics and lean controls. Methylation of seven CpGs in the promoter region of TLR2 was significantly lower in type 2 diabetics compared to obese subjects and lean controls. The methylation levels of both TLRs were significantly correlated with body mass index. Our data suggest that changes in gut microbiota and thus cell wall components are involved in the epigenetic regulation of inflammatory reactions. An improved diet targeted to induce gut microbial balance and in the following even epigenetic changes of

    Diabetes mellitus is known to exacerbate bacterial infection, but its effect on the severity of viral infection has not been well studied. The severity of thrombocytopenia is an indicator of the severity of dengue virus infection. We investigated whether diabetes is associated with thrombocytopenia in dengue-infected patients. We studied clinical characteristics of 644 patients with dengue infection at a university hospital during the epidemic on 1 June 2002 to 31 December 2002 in Taiwan. Platelet counts and biochemical data were compared between patients with and without diabetes. Potential risk factors associated with thrombocytopenia were explored using regression analyses. Dengue-infected patients with diabetes had lower platelet counts than patients without diabetes during the first three days (54.54±51.69 vs. 86.58±63.4 (p≤0.001), 43.98±44.09 vs. 64.52±45.06 (p=0.002), 43.86±35.75 vs. 62.72±51.2 (p=0.012)). Diabetes mellitus, death, dengue shock syndrome (DSS) and dengue hemorrhagic fever (DHF) and increased glutamic-pyruvate transaminase (GPT) levels were significantly associated with lower platelet counts during the first day of hospitalization for dengue fever with regression β of -13.981 (95% confidence interval (CI) -27.587, -0.374), -26.847 (95% CI -37.562, -16.132), and 0.054 (95% CI 0.015, 0.094) respectively. Older age, hypoalbuminemia, and hypertriglyceridemia were independently correlated with thrombocytopenia in dengue patients with or without diabetes with regression β of -2.947 (p=0.004), 2.801 (p=0.005), and -3.568 (p≤0.001), respectively. Diabetic patients with dengue had a higher rate of dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS) than non-diabetic patients. They also had lower blood albumin, were older, and higher triglyceride levels. Older age, hypoalbuminemia, and hypertriglyceridemia were independently correlated with thrombocytopenia in dengue patients. Dengue patients with diabetes tended to have more severe

    Full Text Available The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-old control, obese and insulin-treated diabetic mongrel female dogs (4 animals per group. The parametrial white adipose tissue was sampled and processed to obtain both plasma membrane and microsome subcellular fractions for GLUT4 analysis by Western blotting. There was no significant difference in glycemia and insulinemia between control and obese animals. Diabetic dogs showed hyperglycemia (369.9 ± 89.9 mg/dl. Compared to control, the plasma membrane GLUT4, reported per g tissue, was reduced by 55% (P < 0.01 in obese dogs, and increased by 30% (P < 0.05 in diabetic dogs, and the microsomal GLUT4 was increased by ~45% (P < 0.001 in both obese and diabetic animals. Considering the sum of GLUT4 measured in plasma membrane and microsome as total cellular GLUT4, percent GLUT4 present in plasma membrane was reduced by ~65% (P < 0.001 in obese compared to control and diabetic animals. Since insulin stimulates GLUT4 translocation to the plasma membrane, percent GLUT4 in plasma membrane was divided by the insulinemia at the time of tissue removal and was found to be reduced by 75% (P < 0.01 in obese compared to control dogs. We conclude that the insulin-stimulated translocation of GLUT4 to the cell surface is reduced in obese female dogs. This probably contributes to insulin resistance, which plays an important role in glucose homeostasis in dogs.

    Children who are born to mothers with pediatric-onset type 2 diabetes mellitus are exposed to a hyperglycemic intra-uterine environment throughout pregnancy. The growth patterns and risk of type 2 diabetes in these offspring may be influenced by unique gene-environment interactions during intra-uterine and postnatal life. We established a cohort of offspring of First Nation mothers with onset of type 2 diabetes before age 18 years in Manitoba, Canada. We measured height or length and weight at study entry and annually thereafter with fasting blood glucose in offspring aged ≥ 7 years. We collected birth and breastfeeding history and determined the population-specific hepatic nuclear factor-1α (HNF-1α) G319S genotype of offspring at age 7 years. From July 2003 to April 2008, we enrolled 76 offspring of 37 mothers. Sixty-four percent (23/36) of the offspring aged 2-19 years were obese at initial assessment. The rates of obesity remained constant throughout the 5 years. As of April 2008, 7/28 (25%) of the offspring aged 7-19 years have diabetes including 6/14 (43%) aged 10-19 years. Most offspring with diabetes (5/7, 71%) were obese at diagnosis. All of the 7 offspring with diabetes have 1 or 2 copies of the G319S polymorphism. The prevalence of type 2 diabetes in this cohort of offspring of First Nation women with pediatric-onset type 2 diabetes is the highest ever reported. Obesity is an important postnatal risk factor for type 2 diabetes in this population and may result from a unique gene-environment interaction. © 2011 John Wiley & Sons A/S.

    Resistance training to increase muscle mass and functional capacity is an integral part of diet and exercise programs for the management of obesity and type 2 diabetes. Low-intensity resistance training with slow movement and tonic force generation (LST) may be a practical and safe regimen for elderly obese individuals but the health benefits are uncertain. This study investigated the effects of LST on body composition and metabolic parameters in obese patients with type 2 diabetes. Twenty-six obese patients with type 2 diabetes engaged in LST training during hospitalization and were advised to maintain this regimen for 12 weeks after discharge. We compared lipid profile, arterial stiffness, and body composition before and after LST training. After 12 weeks of LST training, the ratio of lower extremity muscle mass to body weight increased significantly (0.176 ± 0.028 to 0.184 ± 0.023, mean ± SD), while body fat mass and body fat percentage decreased significantly (36.2 ± 10.9 kg to 34.3 ± 9.4 kg and 41.2 ± 8.6% to 40.1 ± 7.7%, respectively). Moreover, high-density lipoprotein cholesterol was significantly increased (42.2 ± 14 mg/dl to 46.3 ± 12.4 mg/dl) and both free fatty acids and lipoprotein(a) were decreased (665.2 ± 212.1 μEq/l to 525.4 ± 231.3 μEq/l and 15.4 ± 18 mg/dl to 13.8 ± 18 mg/dl, respectively). No significant change was observed in arterial stiffness. Although this study was a non-controlled investigation and some confounding factors including dietary intake, medication and compliance with training might affect the study result, a brief (12-week) LST training program may be a safe and effective strategy for the management of obesity and type 2 diabetes.

    Full Text Available Despite recommendations that central obesity assessment should be employed as a marker of cardiometabolic health, no consensus exists regarding measurement protocol. This study examined a range of anthropometric variables and their relationships with cardiometabolic features and type 2 diabetes in order to ascertain whether measurement site influences discriminatory accuracy. In particular, we compared waist circumference (WC measured at two sites: (1 immediately below the lowest rib (WC rib and (2 between the lowest rib and iliac crest (WC midway, which has been recommended by the World Health Organisation and International Diabetes Federation.This was a cross-sectional study involving a random sample of 2,002 men and women aged 46-73 years. Metabolic profiles and WC, hip circumference, pelvic width and body mass index (BMI were determined. Correlation, logistic regression and area under the receiver operating characteristic curve analyses were used to evaluate obesity measurement relationships with metabolic risk phenotypes and type 2 diabetes.WC rib measures displayed the strongest associations with non-optimal lipid and lipoprotein levels, high blood pressure, insulin resistance, impaired fasting glucose, a clustering of metabolic risk features and type 2 diabetes, in both genders. Rib-derived indices improved discrimination of type 2 diabetes by 3-7% compared to BMI and 2-6% compared to WC midway (in men and 5-7% compared to BMI and 4-6% compared to WC midway (in women. A prediction model including BMI and central obesity displayed a significantly higher area under the curve for WC rib (0.78, P=0.003, Rib/height ratio (0.80, P<0.001, Rib/pelvis ratio (0.79, P<0.001, but not for WC midway (0.75, P=0.127, when compared to one with BMI alone (0.74.WC rib is easier to assess and our data suggest that it is a better method for determining obesity-related cardiometabolic risk than WC midway.

    Diabetes mellitus type 2 is a chronic disease with increasing prevalence in western society. Obesity represents a well established risk factor for the development of diabetes mellitus type 2. Several studies on surgical procedures for the treatment of obesity have shown a postoperative reduction of obesity-related co-morbidities. Thus, diabetes mellitus type 2 was shown to resolve or improve in more than 75% of morbidly obese patients (BMI >35) after bariatric surgery. These insights paved the way for the advent of metabolic surgery - a novel field with the goal to improve glucose metabolism in patients with a BMI of less than 35. Encouraging results from mostly observational studies have sparked the interest in the surgical management of diabetes mellitus type 2.

    Overweight and obesity in youth with type 1 diabetes (T1D) is now prevalent and accounts for significant health consequences, including cardiovascular complications and dual diagnosis of type 2 diabetes. Physical activity and lifestyle are modifiable and play an important role in the prevention and management of excessive weight, but it is unclear how these factors relate to overweight and obese youth with T1D. Thus, a systematic review was conducted to examine how physical activity, sedentary behavior, sleep, and diet are related to overweight/obesity in youth with T1D. Seven observational and intervention studies published between 1990 and 2013 were included in the review. Prevalence of overweight ranged from 12.5% to 33.3%. Overweight in youth with T1D was associated with infrequent napping, increased screen time, and skipping breakfast and dinner but was not related to time engaged in physical activity. Weight-related interventions indicated modest weight loss along with improved glycemic control. In light of this review, there is a need for high quality research that examines all levels of activity in youth with T1D to identify lifestyle modification targets for weight prevention and management.

    Rates of pre-gestational obesity and gestational diabetes mellitus (GDM) are increasing in Australia. While both are established risk factors for neonatal hypoglycaemia, the additive effect of both risks on neonatal hypoglycaemia is not well understood. To determine the influence of obesity on neonatal hypoglycaemia among infants born to GDM mothers. The authors hypothesise the presence of a greater frequency and severity of neonatal hypoglycaemia in infants born to obese GDM women. A cohort of 471 singleton GDM pregnancies was retrospectively studied. Women were divided into obese (body mass index (BMI) ≥ 30 kg/m 2 ) and not-obese (BMI mothers were obese, while 36% (146/410) exceeded pregnancy weight gain recommendations. GDM and obesity resulted in a greater frequency of neonatal hypoglycaemia as compared to women with GDM alone (obese 44%, not obese 34%, P = 0.046). Obesity increased the likelihood of having multiple hypoglycaemic episodes (P = 0.022). Excess weight gain increased the likelihood of the neonate requiring intravenous dextrose (P = 0.0012). No differences were found in the likelihood of nursery admissions or lowest plasma glucose levels. Pre-pregnancy obesity and weight gain during pregnancy above the recommended limits increased the likelihood of neonatal hypoglycaemia among infants of GDM mothers. Further studies with larger cohorts are warranted to confirm our findings. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Objective: To identify differences in incidence and clinical manifestations of acute myocardial infarction (AMI) and prevalence of coronary disease risk factors in diabetic and non-diabetics. Design: A prospective longitudinal survey. Place and duration of study: The study was carried out in Armed Forces Institute of Cardiology/National Institute of Heart Diseases (AFIC/NIHD) Rawalpindi, over a period of one month (1st August to 1st September, 1994). Subject and Methods: After fulfilling the inclusion criteria, a total of 100 patients were included in the study. Fifty patients had diabetes and AMI while 50 patients had AMI but were not diabetic. All the patients were studies for at least 15 days in hospital and data collected on a pre-designed proforma. Results: Among diabetic patients, 84% were not insulin-dependant, while remaining 16% were on insulin therapy. Duration of diabetes was over 20 years in 18% between 10 and 20 years in 62% and less than 10 years in 8%. Male to female ratio was 7.3:1 in non-diabetic group while in diabetic group it was 4.5:1. Mean age at the time of the first AMI was 54.6 years in non-diabetic group and 52.8 years in diabetic group, with women in diabetic group having mean age of 51.9 years, men 53.2 years, while non-diabetic women had a mean age of 54.2 years and the men 55 years. Incidence of hypertension was 32% among diabetic patients and 24% among non-diabetics. Lipid abnormalities were 44% in diabetic group and 36% in non-diabetic group the most common mode of presentation in both groups was chest pain or chest discomfort, but one-fourth of the diabetics presented without any chest pain. Q-wave AMI of the anterior wall of the myocardium predominated in both group, but non-Q wave infarctions were more frequent in the diabetic group (28% vs. 16%). Diabetic group tended to be identified later and only half the diabetics with AMI qualified for thrombolytic therapy as compared to more than 2/3 cases of the non-diabetic group

    Inflammation, oxidative stress and dysregulation of adipokines are thought to be pathophysiological mechanisms linking obesity to the development of insulin resistance and atherosclerosis. In adults, bariatric surgery reduces inflammation and oxidative stress, and beneficially changes the levels of several adipokines, but little is known about the postsurgical changes among adolescents. In two separate longitudinal cohorts we evaluated change from baseline of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemo-attractant protein-1 (MCP-1), oxidized low-density lipoprotein cholesterol (oxLDL), adiponectin, leptin and resistin up to 12 months following elective laparoscopic Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG) surgery in adolescents with severe obesity. In cohort 1, which consisted of 39 adolescents (mean age 16.5±1.6 years; 29 females) undergoing either RYGB or VSG, IL-6 (baseline: 2.3±3.4 pg ml(-1) vs 12 months: 0.8±0.6 pg ml(-1), Padolescents (mean age 16.5±1.6 years; 10 females) undergoing RYGB, results were similar: IL-6 (baseline: 1.7±0.9 pg ml(-1) vs 12 months: 0.4±0.9 pg ml(-1), PBariatric surgery produced robust improvements in markers of inflammation, oxidative stress and several adipokines among adolescents with severe obesity, suggesting potential reductions in risk for type 2 diabetes and cardiovascular disease.

    Full Text Available Melatonin and leptin exhibit daily rhythms that may contribute towards changes in metabolic physiology. It remains unclear, however, whether this rhythmicity is altered in obesity or type 2 diabetes (T2DM. We tested the hypothesis that 24-hour profiles of melatonin, leptin and leptin mRNA are altered by metabolic status in laboratory conditions. Men between 45-65 years old were recruited into lean, obese-non-diabetic or obese-T2DM groups. Volunteers followed strict sleep-wake and dietary regimes for 1 week before the laboratory study. They were then maintained in controlled light-dark conditions, semi-recumbent posture and fed hourly iso-energetic drinks during wake periods. Hourly blood samples were collected for hormone analysis. Subcutaneous adipose biopsies were collected 6-hourly for gene expression analysis. Although there was no effect of subject group on the timing of dim light melatonin onset (DLMO, nocturnal plasma melatonin concentration was significantly higher in obese-non-diabetic subjects compared to weight-matched T2DM subjects (p<0.01 and lean controls (p<0.05. Two T2DM subjects failed to produce any detectable melatonin, although did exhibit plasma cortisol rhythms comparable to others in the group. Consistent with the literature, there was a significant (p<0.001 effect of subject group on absolute plasma leptin concentration and, when expressed relative to an individual's 24-hour mean, plasma leptin showed significant (p<0.001 diurnal variation. However, there was no difference in amplitude or timing of leptin rhythms between experimental groups. There was also no significant effect of time on leptin mRNA expression. Despite an overall effect (p<0.05 of experimental group, post-hoc analysis revealed no significant pair-wise effects of group on leptin mRNA expression. Altered plasma melatonin rhythms in weight-matched T2DM and non-diabetic individuals supports a possible role of melatonin in T2DM aetiology. However, neither

    To investigate the correlation between the frequency of dawn phenomenon and obesity in patients with type 2 diabetes. This study was conducted in 98 patients with type 2 diabetes admitted to the Metabolic Disease Hospital of Tianjin Medical University from 2011 to 2014. The subjects were divided into 3 groups according to BMI: the normal weight (BMI 18.5-23.9 kg/m(2), n = 30), the overweight(BMI 24-27.9 kg/m(2), n = 33)and the obesity (BMI ≥ 28.0 kg/m(2), n = 35). All participants underwent continuous glucose monitoring for 72 h. Fasting plasma glucose(FPG), insulin and C-peptide were tested. Frequency of dawn phenomenon among the 3 groups was calculated, and the correlations between dawn phenomenon and its related factors were analyzed. The frequency of dawn phenomenon in type 2 diabetes increased with the increase of BMI in the 3 groups (P obesity groups, respectively. The dawn phenomenon was positively correlated with BMI (r = 0.424, P fasting C-peptide (r = 0.254, P 0.05). The dawn phenomenon is closely associated with obesity and insulin resistance. The frequency of dawn phenomenon increases with BMI.

    Full Text Available Abstract Background 7B2 is a regulator/activator of the prohormone convertase 2 which is involved in the processing of numerous neuropeptides, including insulin, glucagon and pro-opiomelanocortin. We have previously described a suggestive genetic linkage peak with childhood obesity on chr15q12-q14, where the 7B2 encoding gene, SGNE1 is located. The aim of this study is to analyze associations of SGNE1 genetic variation with obesity and metabolism related quantitative traits. Methods We screened SGNE1 for genetic variants in obese children and genotyped 12 frequent single nucleotide polymorphisms (SNPs. Case control analyses were performed in 1,229 obese (534 children and 695 adults, 1,535 individuals with type 2 diabetes and 1,363 controls, all French Caucasians. We also studied 4,922 participants from the D.E.S.I.R prospective population-based cohort. Results We did not find any association between SGNE1 SNPs and childhood or adult obesity. However, the 5' region SNP -1,701A>G associated with higher area under glucose curve after oral glucose tolerance test (p = 0.0005, higher HOMA-IR (p = 0.005 and lower insulinogenic index (p = 0.0003 in obese children. Similar trends were found in obese adults. SNP -1,701A>G did not associate with risk of T2D but tends to associate with incidence of type 2 diabetes (HR = 0.75 95%CI [0.55–1.01]; p = 0.06 in the prospective cohort. Conclusion SGNE1 genetic variation does not contribute to obesity and common forms of T2D but may worsen glucose intolerance and insulin resistance, especially in the background of severe and early onset obesity. Further molecular studies are required to understand the molecular bases involved in this process.

    Full Text Available Marcio C Mancini, Alfredo HalpernObesity and Metabolic Syndrome Group, Endocrinology and Metabolism Department, Faculty of Medicine, University of São Paulo, São Paulo, SP, BrazilAbstract: There has been an increase in the concern about preventing type 2 diabetes mellitus (T2DM, a disease with great and increasing prevalence. The prevalence of obesity, physical inactivity, Western processed diet, important risk factors for the development of T2DM, are also rising. Free fatty acids are increased in obesity and reduce insulin clearance and increase hepatic glucose production. Implementation of a healthy lifestyle has been show to slow the progression of impaired glucose tolerance to T2DM. Orlistat is an inhibitor of lipase activity, with proved efficacy in body weight reduction and long-term management of obesity and more favorable effects on carbohydrate metabolism and it was prospectively shown in XENDOS study that orlistat promoted long-term weight loss and prevented T2DM onset in obese individuals with normal and impaired glucose tolerance at baseline over four years. This benefit could be associated to the weight loss itself, to the limited absorption of lipids and reduction of plasma free fatty acids, to increased production of incretins or to modulation of secretion of cytokines by adipocytes, all effects secondary to orlistat treatment. A proposed strategy is to identify subjects at highest risk to receive a drug intervention, using lifestyle interventions alone at the community level.Keywords: type 2 diabetes mellitus, prevention, diabesity, obesity, metabolic syndrome, orlistat

    Metabolic disorders like diabetes mellitus and obesity may compromise the fertility of men and women. To unveil disease-associated proteomic changes potentially affecting male fertility, the proteomes of sperm cells from type-1 diabetic, type-2 diabetic, non-diabetic obese and clinically healthy individuals were comparatively analyzed by difference gel electrophoresis. The adaptation of a general protein extraction procedure to the solubilization of proteins from sperm cells allowed for the resolution of 3187 fluorescent spots in the difference gel electrophoresis image of the master gel, which contained the entirety of solubilized sperm proteins. Comparison of the pathological and reference proteomes by applying an average abundance ratio setting of 1.6 and a p ≤ 0.05 criterion resulted in the identification of 79 fluorescent spots containing proteins that were present at significantly changed levels in the sperm cells. Biometric evaluation of the fluorescence data followed by mass spectrometric protein identification revealed altered levels of 12, 71, and 13 protein species in the proteomes of the type-1 diabetic, type-2 diabetic, and non-diabetic obese patients, respectively, with considerably enhanced amounts of the same set of one molecular form of semenogelin-1, one form of clusterin, and two forms of lactotransferrin in each group of pathologic samples. Remarkably, β-galactosidase-1-like protein was the only protein that was detected at decreased levels in all three pathologic situations. The former three proteins are part of the eppin (epididymal proteinase inhibitor) protein complex, which is thought to fulfill fertilization-related functions, such as ejaculate sperm protection, motility regulation and gain of competence for acrosome reaction, whereas the putative role of the latter protein to function as a glycosyl hydrolase during sperm maturation remains to be explored at the protein/enzyme level. The strikingly similar differences detected in the

    2014-01-01

    The clinical association between obesity-associated type 2 diabetes (T2D) and periodontitis, coupled with the increasing prevalence of these diseases, justifies studies to identify mechanisms responsible for the vicious feed-forward loop between systemic and oral disease. Changes in the immune system are critical for both obesity-associated T2D and periodontitis and therefore may link these diseases. Recent studies at the intersection of immunology and metabolism have greatly advanced our understanding of the role the immune system plays in the transition between obesity and obesity-associated T2D and have shown that immune cells exhibit similar functional changes in obesity/T2D and periodontitis. Furthermore, myeloid and lymphoid cells likely synergize to promote obesity/T2D-associated periodontitis despite complexities introduced by disease interaction. Thus the groundwork is being laid for researchers to exploit existing models to understand immune cell dysfunction and break the devastating relationship between obesity-associated T2D and oral disease.

    2016-12-13

    The increased prevalence of obesity in children and its complications have led to a greater interest in studying baroreflex sensitivity (BRS) in children. This review of BRS in children and adolescents includes subtopics on: 1. Resting values of BRS and their reproducibility, 2. Genetics of BRS, 3. The role of a primarily low BRS and obesity in the development of hypertension, and 4. Association of diabetes mellitus, BRS, and obesity. The conclusions specific to this age follow from this review: 1. The mean heart rate (HR) influences the measurement of BRS. Since the mean HR decreases during adolescence, HR should be taken into account. 2. A genetic dependency of BRS was found. 3. Low BRS values may precede pathological blood-pressure elevation in children with white-coat hypertension. We hypothesize that low BRS plays an active role in the emergence of hypertension in youth. A contribution of obesity to the development of hypertension was also found. We hypothesize that both factors, a primarily low BRS and obesity, are partially independent risk factors for hypertension in youths. 4. In diabetics, a low BRS compared to healthy children can be associated with insulin resistance. A reversibility of the BRS values could be possible after weight loss.

    Prevention program including lifestyle changes was initiated with the participation of obese and overweight subjects recruited from the practices of 29 family doctors. The aim of the author was to analyse changes of non-HDL-cholesterol levels, especially when triglyceride levels were above 2.26 mmol/l, and when non-HDL cholesterol levels were high in association with low HDL-cholesterol levels in overweight or obese subjects who had no cardiovascular disease and diabetes mellitus. Data obtained from 1192 subjects (424 men and 768 women) before and 12 month after inclusion into the prevention program was analysed. The average level of non-HDL-cholesterol in the whole group of subjects decreased from 4.74 to 4.64 mmol/l, but the change was not significant. However, the average concentration of non-HDL-cholesterol was reduced significantly from 4.87 to 4.4 mmol/l in men, whereas no significant change was detected in women. In cases when triglyceride levels were higher than 2.26 mmol/l, the non-HDL-cholesterol level was reduced by 0.65 mmol/l. In cases when the non-HDL-cholesterol level was high in association with low HDL-cholesterol level, the non-HDL-cholesterol was significantly decreased from 5.22 to 4.48 mmol/l. In addition, in cases when HDL-cholesterol levels were low, the average level of the HDL-cholesterol significantly increased from 0.84 to 1.3 mmol/l. Lifestyle changes decrease the level of atherogenic lipid fractions, particularly in men with high triglyceride levels. Improvement of the atherogenic lipid profile in response to lifestyle changes is related not only to the reduction of atherogenic lipid fractions, but also to the increase of HDL-cholesterol level.

    Full Text Available Background : There are some reports that diabetes and metabolic syndrome (MS are more prevalent among schizophrenia patients. However, there are very few studies in India which have estimated the prevalence of diabetes and MS in schizophrenia patients. Aims : The aim of this study was to determine the prevalence of diabetes, obesity, and MS in subjects with and without schizophrenia. Settings and Design : This case control study comprised of "cases" i.e. subjects with schizophrenia recruited from a schizophrenia centre at Chennai and "controls" i.e. healthy age- and gender-matched subjects without psychiatric illness selected from an ongoing epidemiological study in Chennai in a 1:4 ratio of cases: Controls. Materials and Methods : Fasting plasma glucose and serum lipids were estimated for all subjects. Anthropometric measures including height, weight, and waist circumference were assessed. Diabetes and impaired fasting glucose (IFG were defined using American Diabetes Association criteria. Statistical analysis : One-way ANOVA or student′s "t" test was used to compare continuous variables and Chi-square test to compare proportion between two groups. Results : The study group comprised of 655 subjects, 131 with schizophrenia and a control group of 524 subjects without schizophrenia. The prevalence of the diabetes, IFG, abdominal obesity and MS were significantly higher among subjects with schizophrenia compared to those without schizophrenia-diabetes (15.3% vs. 7.3%, P=0.003, IFG (31.3% vs. 8.6%, P<0.001, abdominal obesity (59.2% vs. 44.7%, P<0.001, and MS (34.4% vs. 24%, P=0.014. Conclusion : In subjects with schizophrenia, the prevalence of diabetes, IFG, abdominal obesity, and MS is significantly higher than in those without schizophrenia.

    To examine the current extent of the obesity problem in 2 large pediatric clinical registries in the US and Europe and to examine the hypotheses that increased body mass index (BMI) z-scores (BMIz) are associated with greater hemoglobin A1c (HbA1c) and increased frequency of severe hypoglycemia in youth with type 1 diabetes (T1D). International (World Health Organization) and national (Centers for Disease Control and Prevention/German Health Interview and Examination Survey for Children and Adolescents) BMI references were used to calculate BMIz in participants (age 2-18 years and ≥ 1 year duration of T1D) enrolled in the T1D Exchange (n = 11,435) and the Diabetes Prospective Follow-up (n = 21,501). Associations between BMIz and HbA1c and severe hypoglycemia were assessed. Participants in both registries had median BMI values that were greater than international and their respective national reference values. BMIz was significantly greater in the T1D Exchange vs the Diabetes Prospective Follow-up (P 1). After stratification by age-group, no differences in BMI between registries existed for children 2-5 years, but differences were confirmed for 6- to 9-, 10- to 13-, and 14- to 17-year age groups (all P 1). Greater BMIz were significantly related to greater HbA1c levels and more frequent occurrence of severe hypoglycemia across the registries, although these associations may not be clinically relevant. Excessive weight is a common problem in children with T1D in Germany and Austria and, especially, in the US. Our data suggest that obesity contributes to the challenges in achieving optimal glycemic control in children and adolescents with T1D. Copyright © 2015 Elsevier Inc. All rights reserved.

    Identification of modifiable behaviors is important for pediatric weight management and obesity prevention programs. This study examined obesogenic behaviors in children with obesity in a Northern California obesity intervention program using data from a parent/teen-completed intake questionnaire covering dietary and lifestyle behaviors (frequency of breakfast, family meals, unhealthy snacking and beverages, fruit/vegetable intake, sleep, screen time, and exercise). Among 7956 children with BMI ≥ 95th percentile, 45.5% were females and 14.2% were 3-5, 44.2% were 6-11, and 41.6% were 12-17 years old. One-quarter (24.9%) were non-Hispanic white, 11.3% were black, 43.5% were Hispanic, and 12.0% were Asian/Pacific Islander. Severe obesity was prevalent (37.4%), especially among blacks, Hispanics, and older children, and was associated with less frequent breakfast and exercise and excess screen time, and in young children it was associated with consumption of sweetened beverages or juice. Unhealthy dietary behaviors, screen time, limited exercise, and sleep were more prevalent in older children and in selected black, Hispanic, and Asian subgroups, where consumption of sweetened beverages or juice was especially high. Overall, obesity severity and obesogenic behaviors increased with age and varied by gender and race/ethnicity. We identified several key prevalent modifiable behaviors that can be targeted by healthcare professionals to reduce obesity when counseling children with obesity and their parents.

    Full Text Available “Boiogito” is a Kampo preparation which has been used since ancient times in patients with obesity of the “asthenic constitution” type, so-called “watery obesity”, and its effect has been recognized clinically. In this study, we investigated the anti-obesity effect of Boiogito in the TSOD (Tsumura Suzuki Obese Diabetes mouse, a model of spontaneous obese type II diabetes mellitus. Boiogito showed a significant anti-obesity effect in TSOD mice by suppressing body weight gain in a dosage-dependent manner. In addition, Boiogito showed significant ameliorative effects on features of metabolic syndrome such as hyperinsulinemia, fasting hyperglycemia and abnormal lipid metabolism. Regarding lipid accumulation in TSOD mice, Boiogito showed a significant suppressive effect on accumulation of subcutaneous fat, but the effect on the visceral fat accumulation that constitutes the basis of metabolic syndrome was weak, and the suppressive effect on insulin resistance was also weak. Furthermore, Boiogito did not alleviate the abnormal glucose tolerance, the hypertension or the peripheral neuropathy characteristically developed in the TSOD mice. In contrast, in the TSNO (Tsumura Suzuki Non-Obesity mice used as controls, Boiogito suppressed body weight gain and accumulation of subcutaneous and visceral fat. The above results suggested that Boiogito is effective as an anti-obesity drug against obesity of the “asthenic constitution” type in which subcutaneous fat accumulates, but cannot be expected to exert a preventive effect against various symptoms of metabolic syndrome that are based on visceral fat accumulation.

    Full Text Available AbstractINTRODUCTION: Liposuction is a surgical procedure effective in reducing body fat, withgrowing application in conjunction with diet and exercise therapy in the treatment of obesity.In view of the positive effect of weight reduction on cardiovascular disease (CVD riskfactors, such as body mass index (BMI, waist circumference (WC, waist-to-hip ratio(WHR, systolic and diastolic pressure, lipid profile, fasting blood sugar, insulin resistance,inflammatory markers (e.g. chronic reactive protein: CRP, antioxidant capacity, fibrinogenand lipoprotein A (Lpa, this study was conducted to assess the effect of liposuction as atherapeutic procedure in the treatment of obesity.METHODS: A total of 24 non-diabetic obese women (BMI>30 with a mean age of48.7±7.3 years were studied. Before liposuction, the subjects filled out questionnairesobtaining demographic information. Complete physical examination, measurement of waistand hip circumference, height, weight and calculation of WHR and BMI were performed.Fasting blood samples were taken to measure fasting blood glucose, total cholesterol, highdensitylipoprotein (HDL, low-density lipoprotein (LDL, triglyceride (TG, fibrinogen,antioxidant capacity, CRP, lipoprotein A, serum insulin, and insulin resistance. Allmeasurements and physical examinations were repeated 12-14 weeks after liposuction.Data were analyzed with SPSS11 software using paired t-test and repeated measureANOVA.RESULTS: WHR, BMI and LDL decreased significantly following liposuction (P<0.05.Other parameters, however, did not change significantly, although there were signs ofpositive changes.DISCUSSION: Liposuction decreases BMI, WHR and LDL within 12-14 weeks ofliposuction. Providing these reductions are maintained, liposuction may prove valuable inreducing CVD risk factors, besides offering a means for obesity control.Keywords • Liposuction • Obesity

    To determine an influence of alpha-lipoic acid to reduction of body weight and regulation of total cholesterol concentration, triglycerides and glucose serum levels in obese patients with diabetes mellitus type 2. A prospective study includes two groups of obese patients with diabetes mellitus and signs of peripheral polyneuropathia: examined group (30 patients; 15 females and 15 males), and control group (30 patients; 12 females and 18 males). All were treated with metformin (850-1700 mg/day). Examined patients were additionally treated with alpha-lipoic acid 600 mg/day during 20 weeks. Body mass index and concentrations of total cholesterol, triglycerides and glucose in serum were compared before and after the treatment. The group treated with 600 mg alpha-lipoic acid lost significantly more weight, and had lower triglyceride level than the control group. There were no significant differences in total cholesterol and glucose serum levels between the groups. Alpha-lipoic acid of 600 mg/day treatment have influenced weight and triglycerides loss in obese patients with diabetes mellitus type 2. It should be considered as an important additive therapy in obese patients with diabetes mellitus type 2. Copyright© by the Medical Assotiation of Zenica-Doboj Canton.

    Full Text Available Abstract Objective To describe current prevalence of obesity and related non-communicable diseases (NCDs in expatriates living in the United Arab Emirates (UAE. Methods We used data from the cross-sectional UAE National Diabetes and Lifestyle Study (UAEDIAB, which surveyed adult expatriates living in the UAE for at least 4 years. We report crude prevalence of overweight and obesity, indicated by gender and ethnicity-specific body mass index (BMI, waist circumference (WC and waist-to-hip ratio (WHR cut-offs, by lifestyle and biomedical characteristics, as well as age and sex-adjusted odds ratios. Results Out of a total of 3064 recruited expatriates (response rate 68%, 2724 had completed all stages of the UAEDIAB study. Expatriates were; 81% men, mean age 38 years (range 18–80, 71% South East Asians, and 36% university graduates. In this sample, the prevalence of overweight and obesity, by BMI, were 43.0 and 32.3%, respectively. 52.4 and 56.5% of participants were at a substantially increased risk according to WC and WHR, respectively. The prevalence of diabetes, hypertension and hypercholesterolemia were 15.5, 31.8, and 51.7%, respectively, with the prevalence of each being higher in those with obesity. Conclusion Prevalence of obesity and associated NCDs are extremely high in UAE expatriates. Without comprehensive prevention and management, levels of disease will continue to increase and productivity will fall.

    2014-01-01

    The incidence of overweight and obesity among children has increased dramatically in recent decades, with about one-third of children in the U.S. currently being either overweight or obese. Being overweight in early childhood increases risk for later obesity. There is evidence for the efficacy of family-based behavioral treatment to control weight and improve health outcomes. Obesity-related health risks have been documented, including metabolic syndrome. There is also increasing incidence of type 2 diabetes (T2D) among youth in recent years, with obesity and family history of T2D generally present. Lower income and ethnic minority status are associated with both obesity and T2D in youth. Most youth with T2D do not achieve optimal glycemic control, and are at high risk for later health complications. Obesity and T2D represent significant public health issues with potentially great personal and societal cost. Research addressing the prevention of obesity and T2D among youth is urgently needed.

    Patients with schizophrenia have significantly shorter life expectancy than the general population, and a problem they commonly face is an unhealthy lifestyle, which can lead to obesity and metabolic syndrome. There is a very clear need to determine the prevalence of obesity, hypertension, hyperlipidemia, and diabetes mellitus which are components of metabolic syndrome in patients with schizophrenia, but there has been a paucity of large-scale studies examining this situation in Japan. The aim of our study was to address this need. We conducted a large-scale investigation of the prevalence of obesity, hypertension, hyperlipidemia, and diabetes mellitus using a questionnaire in 520 outpatient facilities and 247 inpatient facilities of the Japan Psychiatric Hospitals Association between January 2012 and July 2013. There were 7,655 outpatients and 15,461 inpatients with schizophrenia. The outpatients had significantly higher prevalence of obesity, hypertension, hypertriglyceridemia, hyper-LDL cholesterolemia, and diabetes mellitus than the inpatients. The prevalence of hypo-HDL cholesterolemia was higher in inpatients than outpatients. Age-specific analysis showed the prevalence of obesity, hypertension, hypertriglyceridemia, hyper-LDL cholesterolemia, and diabetes mellitus among outpatients to be 2- to 3-fold higher than among inpatients. In individuals aged ≥60 years, the prevalence of obesity and DM among outpatients was about 3-fold higher than among inpatients. Japanese outpatients with schizophrenia were more likely to have physical risk such as obesity, hypertension, hyperlipidemia, and diabetes mellitus than inpatients. The physical risk to patients with schizophrenia may be affected by environmental parameters, such as type of care. The physical risk to Japanese patients with schizophrenia demands greater attention.

    There is strong evidence that increased physical activity is beneficial for blood glucose homeostasis and the prevention of obesity and type 2 diabetes mellitus. This chapter takes a life course approach with an emphasis on the intrauterine and childhood stages of life. Firstly, growth and development at critical periods with a focus on skeletal muscle and adipose tissue; then, obesity and type 2 diabetes mellitus are considered in relation to physical activity and sedentary behaviour. The importance of the development of fundamental movement skills in early childhood for both physical fitness and also growth and development is emphasised. Physical activity guidelines in westernised countries are examined for commonalities. Finally, the effective translation of the evidence base for the benefits of physical activity into randomised controlled trials and then into real-world public health services that are sustainable is addressed with a case study from New Zealand of Project Energize--a through-school physical activity and nutrition intervention. Physical activity, alongside a 'healthy diet' is arguably the best preventive measure and treatment for both obesity and type 2 diabetes. It is an essential and normal activity of daily life, and all aspects of the life course and the environment should support physical activity.

    Obesity-induced diabetes is characterized by hyperglycemia, insulin resistance, and progressive beta cell failure. In islets of mice with obesity-induced diabetes, we observe increased beta cell death and impaired autophagic flux. We hypothesized that intermittent fasting, a clinically sustainable therapeutic strategy, stimulates autophagic flux to ameliorate obesity-induced diabetes. Our data show that despite continued high-fat intake, intermittent fasting restores autophagic flux in islets and improves glucose tolerance by enhancing glucose-stimulated insulin secretion, beta cell survival, and nuclear expression of NEUROG3, a marker of pancreatic regeneration. In contrast, intermittent fasting does not rescue beta-cell death or induce NEUROG3 expression in obese mice with lysosomal dysfunction secondary to deficiency of the lysosomal membrane protein, LAMP2 or haplo-insufficiency of BECN1/Beclin 1, a protein critical for autophagosome formation. Moreover, intermittent fasting is sufficient to provoke beta cell death in nonobese lamp2 null mice, attesting to a critical role for lysosome function in beta cell homeostasis under fasting conditions. Beta cells in intermittently-fasted LAMP2- or BECN1-deficient mice exhibit markers of autophagic failure with accumulation of damaged mitochondria and upregulation of oxidative stress. Thus, intermittent fasting preserves organelle quality via the autophagy-lysosome pathway to enhance beta cell survival and stimulates markers of regeneration in obesity-induced diabetes.

    Early signs of renal complications can be common in youths with type 1 diabetes (T1D). Recently, there has been an increasing interest in potential renal complications associated with obesity, paralleling the epidemics of this condition, although there are limited data in children. Obese children and adolescents present signs of early alterations in renal function similar to non-obese peers with T1D. Eighty-three obese (age: 11.6 ± 3.0 yr), 164 non-obese T1D (age: 12.4 ± 3.2 yr), and 71 non-obese control (age: 12.3 ± 3.2 yr) children and adolescents were enrolled in the study. Anthropometric parameters and blood pressure were measured. Renal function was assessed by albumin excretion rate (AER), serum cystatin C, creatinine and estimated glomerular filtration rate (e-GFR), calculated using the Bouvet's formula. Obese and non-obese T1D youths had similar AER [8.9(5.9-10.8) vs. 8.7(5.9-13.1) µg/min] and e-GFR levels (114.8 ± 19.6 vs. 113.4 ± 19.1 mL/min), which were higher than in controls [AER: 8.1(5.9-8.7) µg/min, e-GFR: 104.7 ± 18.9 mL/min]. Prevalence of microalbuminuria and hyperfiltration was similar between obese and T1D youths and higher than their control peers (6.0 vs. 8.0 vs. 0%, p = 0.02; 15.9 vs. 15.9 vs. 4.3%, p = 0.03, respectively). Body mass index (BMI) z-score was independently related to e-GFR (r = 0.328; p 1), and AER (r = 0.138; p = 0.017). Hemoglobin A1c (HbA1c) correlated with AER (r = 0.148; p = 0.007) but not with eGFR (r = 0.041; p = 0.310). Obese children and adolescents show early alterations in renal function, compared to normal weight peers, and they have similar renal profiles than age-matched peers with T1D. © 2014 John Wiley & Sons A/S.

  4. Plasma lysophosphatidylcholine levels are reduced in obesity and type 2 diabetes.

    Directory of Open Access Journals (Sweden)

    Melissa N Barber

    Full Text Available BACKGROUND: Obesity and type 2 diabetes (T2DM are associated with increased circulating free fatty acids and triacylglycerols. However, very little is known about specific molecular lipid species associated with these diseases. In order to gain further insight into this, we performed plasma lipidomic analysis in a rodent model of obesity and insulin resistance as well as in lean, obese and obese individuals with T2DM. METHODOLOGY/PRINCIPAL FINDINGS: Lipidomic analysis using liquid chromatography coupled to mass spectrometry revealed marked changes in the plasma of 12 week high fat fed mice. Although a number of triacylglycerol and diacylglycerol species were elevated along with of a number of sphingolipids, a particularly interesting finding was the high fat diet (HFD-induced reduction in lysophosphatidylcholine (LPC levels. As liver, skeletal muscle and adipose tissue play an important role in metabolism, we next determined whether the HFD altered LPCs in these tissues. In contrast to our findings in plasma, only very modest changes in tissue LPCs were noted. To determine when the change in plasma LPCs occurred in response to the HFD, mice were studied after 1, 3 and 6 weeks of HFD. The HFD caused rapid alterations in plasma LPCs with most changes occurring within the first week. Consistent with our rodent model, data from our small human cohort showed a reduction in a number of LPC species in obese and obese individuals with T2DM. Interestingly, no differences were found between the obese otherwise healthy individuals and the obese T2DM patients. CONCLUSION: Irrespective of species, our lipidomic profiling revealed a generalized decrease in circulating LPC species in states of obesity. Moreover, our data indicate that diet and adiposity, rather than insulin resistance or diabetes per se, play an important role in altering the plasma LPC profile.

    Non-alcoholic fatty liver (NASH) is widely distributed around the world and is more common in subjects with dyslipidemia, metabolic syndrome obese and DM2 (34-74%). However, the prevalence of cirrhosis by NASH in general population is unknown which is still subject of research. To determine if there are significant differences between metabolic parameters of non-alcoholic fatty liver in controlled versus uncontrolled diabetes type 2 of recent diagnosis. retrospective case-control study, performed in the Hospital Guillermo Almenara Irigoyen, Lima, Peru from November 2014 to February 2015.This study included 231 patients: 147 patients (NASH with DM2 of recent diagnosis and poor control) and 84 patients (NASH with DM2 ofrecent diagnosis and adequate control). Levene test for evaluating homogeneity of variances intra groups and parametric test for independent samples. After applying Levene test of homogeneity and student test, significant metabolic parameters were the triglycerides, HbA1C level, metformin dose and gender. It is important in diabetic patients to diagnose NASH early for a tighter control, not only of glucose but other metabolic parameters mainly triglycerides which strongly supports existing concept of "multiple hits" which considers NASH affects glucose homeostasis, and it could be the starting point of new research to improve interventions for decreasing progression from to cirrhosis in diabetic patients and also to delay progression of diabetes mellitus in patients with non alcoholic steatohepatitis.

    The rising rates, high prevalence, and adverse consequences of obesity and diabetes call for new approaches to the complex behaviors needed to prevent and manage these conditions. Virtual reality (VR) technologies, which provide controllable, multisensory, interactive three-dimensional (3D) stimulus environments, are a potentially valuable means of engaging patients in interventions that foster more healthful eating and physical activity patterns. Furthermore, the capacity of VR technologies to motivate, record, and measure human performance represents a novel and useful modality for conducting research. This article summarizes background information and discussions for a joint July 2010 National Institutes of Health - Department of Defense workshop entitled Virtual Reality Technologies for Research and Education in Obesity and Diabetes. The workshop explored the research potential of VR technologies as tools for behavioral and neuroscience studies in diabetes and obesity, and the practical potential of VR in fostering more effective utilization of diabetes- and obesity-related nutrition and lifestyle information. Virtual reality technologies were considered especially relevant for fostering desirable health-related behaviors through motivational reinforcement, personalized teaching approaches, and social networking. Virtual reality might also be a means of extending the availability and capacity of health care providers. Progress in the field will be enhanced by further developing available platforms and taking advantage of VR's capabilities as a research tool for well-designed hypothesis-testing behavioral science. Multidisciplinary collaborations are needed between the technology industry and academia, and among researchers in biomedical, behavioral, pedagogical, and computer science disciplines. Research priorities and funding opportunities for use of VR to improve prevention and management of obesity and diabetes can be found at agency websites (National

    Full Text Available Perivascular adipose tissue is a part of blood vessel wall, regulating endovascular homeostasis, endothelial and smooth muscle cells functioning. Under physiological conditions, perivascular tissue provides beneficial anticontractile effect, though undergoes structural and functional changes in obesity, atherosclerosis and diabetes mellitus type2.Collected data suggest the possible key role of perivascular adipose tissue in the pathogenesis of these diseases. Perivascular tissue has been determined as an independent cardiovascular risk factor, regardless of visceral obesity. General mechanisms include a local low-grade inflammation, oxidative stress, tissue renin-angiotensin-aldosterone system activation, paracrine and metabolic alterations. Properties of perivascular adipose tissue depend on the certain type of adipocytes it contains. Brown adipocytes are well known for their metabolic preferences, however it has been shown recently that brown perivascular tissue can contribute to dyslipidemia under some conditions.  The aim of this review is to discuss the current literature understanding of perivascular adipose tissue specifics, changes in its activity, secretory and genetic profilein a course of the most common non-infectious diseases development, as well as molecular mechanisms of its functioning. We also discuss perspectives of target interventions using metabolic pathways and genes of perivascular tissue, for the effective prevention of obesity, diabetes mellitus type2 and cardiovascular diseases.

    Full Text Available Background: Diabetes mellitus is known to exacerbate bacterial infection, but its effect on the severity of viral infection has not been well studied. The severity of thrombocytopenia is an indicator of the severity of dengue virus infection. We investigated whether diabetes is associated with thrombocytopenia in dengue-infected patients. Methods: We studied clinical characteristics of 644 patients with dengue infection at a university hospital during the epidemic on 1 June 2002 to 31 December 2002 in Taiwan. Platelet counts and biochemical data were compared between patients with and without diabetes. Potential risk factors associated with thrombocytopenia were explored using regression analyses. Results: Dengue-infected patients with diabetes had lower platelet counts than patients without diabetes during the first three days (54.54 ± 51.69 vs. 86.58 ± 63.4 (p ≤ 0.001, 43.98 ± 44.09 vs. 64.52 ± 45.06 (p = 0.002, 43.86 ± 35.75 vs. 62.72 ± 51.2 (p = 0.012. Diabetes mellitus, death, dengue shock syndrome (DSS and dengue hemorrhagic fever (DHF and increased glutamic-pyruvate transaminase (GPT levels were significantly associated with lower platelet counts during the first day of hospitalization for dengue fever with regression β of −13.981 (95% confidence interval (CI −27.587, −0.374, −26.847 (95% CI −37.562, −16.132, and 0.054 (95% CI 0.015, 0.094 respectively. Older age, hypoalbuminemia, and hypertriglyceridemia were independently correlated with thrombocytopenia in dengue patients with or without diabetes with regression β of −2.947 (p = 0.004, 2.801 (p = 0.005, and −3.568 (p ≤ 0.001, respectively. Diabetic patients with dengue had a higher rate of dengue hemorrhagic fever (DHF/dengue shock syndrome (DSS than non-diabetic patients.

    Aortic valve calcification (AVC) is common in the elderly and associated with increased cardiovascular mortality, while diabetes is one of the confirmed risk factors for coronary artery disease (CAD). In this study, we aimed to evaluate the prevalence and severity of CAD in type-2 diabetic patients with AVC. From June to December in 2007, a total of 325 consecutive patients with chest pain or chest distress were admitted for coronary angiography. The severity of CAD was evaluated by the Gensini score and the number of stenosed vessels. All patients underwent transthoracic echocardiography for detecting AVC. Compared with the patients without diabetes (n = 221), the type-2 diabetic patients (n = 104) had a similar prevalence of CAD (66.5% vs. 72.1%, P = 0.312). Further classified by the presence of AVC, patients with AVC had a higher prevalence of CAD, average Gensini score and the number of stenosed vessels, both in the group with and without diabetes. It was also demonstrated that the odds ratio (OR) of AVC for CAD in the diabetic patients was higher than in the non-diabetic ones (3.405 vs 2.515) after chi-square analysis (single-variable). However, at multivariable logistic regression analysis for CAD, the OR of AVC was 3.757 (P = 0.03) in diabetic group, while it did not achieve statistical significance in the non-diabetic group (OR = 2.130, P= 0.074). Type-2 diabetic patients with AVC had a higher prevalence of and more severe CAD.

    Type 2 diabetes and obesity, which are frequently comorbid, have been associated with cognitive impairment. We aim to examine the potential modulating effect between obesity and diabetes on cognitive impairment. We recruited 865 adults (aged ≥55years) lived in a village of Xi'an in China from October 2014 to March 2015. All participants underwent biomedical and neuropsychological assessment. Relations of diabetes and abdominal obesity to cognitive impairment were examined in multiple regression models. A total of 155 participants (17.9%) presented with the diagnosis of cognitive impairment. Diabetes or obesity alone wasn't significantly associated with cognitive impairment. Interaction analysis showed a significant interaction between abdominal obesity and diabetes on cognitive impairment. Stratified multivariate analysis revealed that the association between diabetes and cognitive impairment was positive in participants with abdominal obesity (OR 2.436, 95% CI 1.345-4.411, p=0.003, in diabetics with high WC, and OR 2.348, 95% CI 1.373-4.014, p=0.002, in diabetics with high WHR), but negative in those without abdominal obesity. Type 2 diabetes interacts with abdominal obesity to be associated with an increased risk of cognitive impairment by more than two times. Copyright © 2017 Elsevier Inc. All rights reserved.

    The principal objective of this investigation was to identify novel cytokine associations with BMI and type 2 diabetes (T2D). Cytokines were profiled from African American women with obesity who donated plasma to the Komen Tissue Bank. Multiplex bead arrays of analytes were used to quantify 88 cytokines and chemokines in association with clinical diagnoses of metabolic health. Regression models were generated after elimination of outliers. Among women with obesity, T2D was associated with breast adipocyte hypertrophy and with six plasma analytes, including four chemokines (chemokine [C-C motif] ligand 2, chemokine [C-C motif] ligand 16, chemokine [C-X-C motif] ligand 1, and chemokine [C-X-C motif] ligand 16) and two growth factors (interleukin 2 and epidermal growth factor). In addition, three analytes were associated with obesity independently of diabetes: interleukin 4, soluble CD40 ligand, and chemokine (C-C motif) ligand 3. Profiling of inflammatory cytokines combined with measures of BMI may produce a more personalized risk assessment for obesity-associated disease in African American women. © 2017 The Obesity Society.

    Obesity, diabetes and hypertension are major worldwide interconnected problems. The aim of this study was to investigate body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure (SBP and DPB) responses to circuit weight training (CWT) or aerobic exercise training (AET) in obese diabetic hypertensive patients (ODHP). Fifty-nine ODHP were randomly assigned into CWT, AET and control groups. Either CWT or AET was performed thrice weekly for 12 weeks. Variables were evaluated pre-training (evaluation-1), after 3 months (evaluation-2) and 1 month post-training cessation (evaluation-3). At evaluation-2, BMI, WC, SBP, DBP mean values and percentages of decrease were 31.56±1.48 (9.23%), 104±5.97 (6.2%), 141±2.2 (3.09%), 91.2±1.24 (2.98%) and 32.09±1.21 (7.11%), 107.66±3.92 (3.07%), 138.3±1.17 (4.79%), 88.05±1.05 (6.02%) for CWT and AET groups respectively (Pobesity indices, AET is still the best intervention to lower blood pressure in ODHP, for a more extended period of time.

HS-H significantly reduced the intake of food and water and body weight loss as well as levels of blood glucose, serum cholesterol, triglyceride, lipoprotein, oxidative stress, showed a protective hepatic effect, and increased HDL-cholesterol, serum insulin in diabetic mice. The mice fed on the high-fat diet and treated with AL-H showed inhibitory activity on the lipid metabolism decreasing body weight and weight of the liver and visceral adipose tissues and cholesterol and triglycerides in the liver. We conclude that AL-H can efficiently reduce serum glucose and inhibit insulin resistance, lipid abnormalities, and oxidative stress in MD and SD mice. Our results demonstrate an antiobesity effect reducing lipid droplet accumulation in the liver, indicating that its therapeutic properties may be due to the interaction plant components soluble in the hexane extract, with any of the multiple targets involved in obesity and diabetes pathogenesis.

    The present study evaluated the performance of three novel obese indicators, visceral adiposity index (VAI), lipid accumulation product (LAP) and waist circumference-triglyceride index (WTI), for identifying metabolic syndrome(MetS) in type 2 diabetes. A cross-sectional study was conducted on 711 type 2 diabetes in Qinhuangdao. The MetS was defined as the definition of Chinese Diabetes Society. Receiver operating characteristic curve analyses were performed to assess the accuracy of three obese indicators as diagnostic tests for MetS. The prevalence of MetS was 71.3%. In men, among all three obese indicators, the LAP had the highest area under curve (AUC) value (AUC = 0.894), followed by VAI (AUC = 0.860) and WTI (AUC = 0.855). In women, among all three obese indicators, the LAP had the highest AUC value (AUC = 0.906), followed by WTI (AUC = 0.887) and VAI (AUC = 0.881). However. there was no significant difference between the three obese indicators(P > 0.05). Three obese indicators were effective indicators for the screening of MetS, LAP and WTI are more simple.

    Full Text Available Background. Psychological stress is known to be a relevant risk factor for many inflammatory conditions, including periodontal disease. A few studies have probed the relationship between obesity and periodontal disease. Therefore this cross-sectional study was aimed to examine the relationship between psychological stress and obesity and periodontal disease in smokers and non-smokers. Methods. The participants included 90 patients, equally divided into three groups of non-smokers and periodontally healthy, non-smokers and smokers with untreated moderate-to-severe chronic periodontitis. Socioeconomic data, psychosocial measurements, physical parameters and clinical findings of PPD, CAL, PI and GI were recorded. Results. The clinical parameters were assessed for three groups in three different anxiety levels of mild, moderate and se-vere. Intra-group comparison of PPD and CAL in the three anxiety levels showed increased periodontal destruction with an increase in anxiety levels, the results being statistically highly significant for PPD differences in smokers (P < 0.0001. The mean differences in PPD and CAL in severe anxiety levels between smokers and non-smokers were 0.68 mm and 0.70 mm and both the findings were statistically significant. The mean PPD and CAL in smoker and non-smoker groups in obese patients was higher as compared to non-obese patients and the differences were highly significant (P < 0.001. Conclusion. The results of our study indicated a positive and strong correlation between anxiety, obesity and periodontal disease in smokers and non-smokers. Smoking appears to further attenuate this association.

    Dumping syndrome is one of ten most common complications in morbidly obese patients operated. Recent studies in relation to type 2 diabetes mellitus (DM2) in patients submitted to gastric bypass led us to examine the different outcomes in this group of patients. Our objective was to determine the difference in the prevalence of dumping syndrome in patients with DM2 submitted to gastric bypass. In this retrospective study, 49 diabetic and 54 non-diabetic morbidly obese patients were submitted to gastric bypass and followed up at 3, 6, and 12 months after surgery. The occurrence of dumping was determined by the patient's medical chart, where it was considered positive if recorded in at least one of three evaluations. The 103 patients evaluated had a mean BMI of 49.5 +/- 9.3 kg/m(2) and mean age of 38 +/- 9.7 years, with 75.7% being women. The prevalence of dumping syndrome in this population was 24.3%. The prevalence of dumping was greater in patients with DM2 (44.9%) when compared to the control group (5.6%; p DM2 as the only variable associated with dumping syndrome. Dumping syndrome is a common postoperative complication in gastric bypass. Patients with DM2 show a greater postoperative prevalence of dumping.

    Dicarbonyl compounds are formed as byproducts of glycolysis and are key mediators of diabetic complications. However, evidence of postprandial α-dicarbonyl formation in humans is lacking, and interventions to reduce α-dicarbonyls have not yet been investigated. Therefore, we investigated postprandial α-dicarbonyl levels in obese women without and with type 2 diabetes. Furthermore, we evaluated whether a diet very low in energy (very low calorie diet [VLCD]) or Roux-en-Y gastric bypass (RYGB) reduces α-dicarbonyl stress in obese women with type 2 diabetes. In lean (n = 12) and obese women without (n = 27) or with type 2 diabetes (n = 27), we measured the α-dicarbonyls, methylglyoxal (MGO), glyoxal (GO) and 3-deoxyglucosone (3-DG), and glucose in fasting and postprandial plasma samples obtained during a mixed meal test. Obese women with type 2 diabetes underwent either a VLCD or RYGB. Three weeks after the intervention, individuals underwent a second mixed meal test. Obese women with type 2 diabetes had higher fasting and particularly higher postprandial plasma α-dicarbonyl levels, compared with those without diabetes. After three weeks of a VLCD, postprandial α-dicarbonyl levels in diabetic women were significantly reduced (AUC MGO -14%, GO -16%, 3-DG -25%), mainly through reduction of fasting plasma α-dicarbonyls (MGO -13%, GO -13%, 3-DG -33%). Similar results were found after RYGB. This study shows that type 2 diabetes is characterised by increased fasting and postprandial plasma α-dicarbonyl stress, which can be reduced by improving glucose metabolism through a VLCD or RYGB. These data highlight the potential to reduce reactive α-dicarbonyls in obese individuals with type 2 diabetes. ClinicalTrials.gov NCT01167959.

  2. Why Weight? An Analytic Review of Obesity Management, Diabetes Prevention, and Cardiovascular Risk Reduction.

    In this review, we examine one of the ironies of American health care-that we pay more for disease management than disease prevention. Instead of preventing type 2 diabetes (T2DM) by treating its precursor, obesity, we fail to provide sufficient insurance coverage for weight management only to fund the more costly burden of overt T2DM. There is a vital need for expanded insurance coverage to help foster a weight-centric approach to T2DM management. This includes broader coverage of anti-diabetic medications with evidence of cardiovascular risk reduction and mortality benefit, anti-obesity pharmacotherapy, bariatric surgery, weight loss devices, endoscopic bariatric therapies, and lifestyle interventions for the treatment of obesity. The fundamental question to ask is why weight? Why wait to go after obesity until its end-stage sequelae cause intractable conditions? Instead of managing the complications of T2DM, consider preventing them by tackling obesity.

    Diabetes knowledge has been shown to improve glycemic control and associate with several demographic parameters. In Greece, a country with high obesity rates, disease knowledge has never been evaluated in diabetic patients. This cross sectional study aimed to assess diabetes knowledge and its associations between social and demographic parameters, among Greek type 2 diabetes mellitus (T2DM) patients. One hundred fifty nine patients with T2DM were recruited from an urban and a rural clinic in Greece. Diabetes knowledge was assessed with the Brief Diabetes Knowledge Test (DKT). Basic anthropometry was performed. Data regarding glycemic control and sociodemographic characteristics were collected from the patients' medical files. Greek T2DM patients demonstrated poor disease knowledge (mean DKT score 8.3±2.2/14.0 and mean DKT as a percent of correct answers 59.6±15.8%). No differences were observed between sex, place of residence, or glycemic control, among subjects. Patients with higher education demonstrated greater diabetes knowledge. Simple obesity with concurrent central obesity or suboptimal glycemic control decreased diabetes knowledge among participants. Additionally, waist circumference was inversely correlated to diabetes knowledge. Based on the DKT, Greek patients exhibit poor diabetes knowledge. This study provides evidence for the need for better diabetes education in order to ameliorate disease outcome. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

    We examined changes in the prevalence of diabetes, obesity, and overweight in 412,881 Korean men in birth cohorts from 1933 to 1972 over 8 years from 1992 to 2000 and separately analyzed the effects of age, time period, and birth cohort. The study included male employees of Korean government organizations and schools who were between 20 and 59 years of age in 1992. Diabetes was diagnosed on the basis of self-reports in 1992 or fasting blood glucose levels (>or=126 mg/ml, 7.0 mmol/l). The age-period-cohort model was used to estimate the effects of age, time period, and birth cohort. In Korean male birth cohorts from 1933 to 1972, the age-specific prevalence of diabetes, obesity, and overweight in men aged 28-59 years increased annually by 0.41% (3.03 to 6.29%), 0.18% (0.70 to 2.16%), and 1.49% (23.48 to 35.41%), respectively, from 1992 to 2000. The relative change in diabetes was largest among the younger cohorts (>400% increase over 8 years) and corresponded to the change in obesity. Apart from the contribution of age, clear cohort and period effects were evident for diabetes, although the magnitude of the effect was slightly less than that for obesity. Prevention of diabetes through the control of obesity, particularly in young men, clearly needs to be emphasized.

    Full Text Available Identification of modifiable behaviors is important for pediatric weight management and obesity prevention programs. This study examined obesogenic behaviors in children with obesity in a Northern California obesity intervention program using data from a parent/teen-completed intake questionnaire covering dietary and lifestyle behaviors (frequency of breakfast, family meals, unhealthy snacking and beverages, fruit/vegetable intake, sleep, screen time, and exercise. Among 7956 children with BMI ≥ 95th percentile, 45.5% were females and 14.2% were 3–5, 44.2% were 6–11, and 41.6% were 12–17 years old. One-quarter (24.9% were non-Hispanic white, 11.3% were black, 43.5% were Hispanic, and 12.0% were Asian/Pacific Islander. Severe obesity was prevalent (37.4%, especially among blacks, Hispanics, and older children, and was associated with less frequent breakfast and exercise and excess screen time, and in young children it was associated with consumption of sweetened beverages or juice. Unhealthy dietary behaviors, screen time, limited exercise, and sleep were more prevalent in older children and in selected black, Hispanic, and Asian subgroups, where consumption of sweetened beverages or juice was especially high. Overall, obesity severity and obesogenic behaviors increased with age and varied by gender and race/ethnicity. We identified several key prevalent modifiable behaviors that can be targeted by healthcare professionals to reduce obesity when counseling children with obesity and their parents.

  6. The severity of nocturnal hypoxia but not abdominal adiposity is associated with insulin resistance in non-obese men with sleep apnea.

    Anne-Laure Borel

    Full Text Available BACKGROUND: Beyond obesity, sleep apnea syndrome is frequently associated with excess abdominal adiposity that could contribute to the deteriorated cardiometabolic risk profile of apneic patients. METHODS: The present study addressed the respective contribution of the severity of sleep apnea syndrome and excess abdominal adiposity to the cardiometabolic risk profile of 38 non obese men with polysomnography-diagnosed sleep apnea syndrome (apnea-hypopnea index >15 events/hour. These otherwise healthy men performed a 75g-oral glucose tolerance test (OGTT with plasma lipid/inflammatory and redox profiles. Twenty-one apneic men with high-waist circumference (>94 cm were compared to 17 apneic men with low-waist circumference. RESULTS: Apneic men with high-waist circumference had higher AUC glucose and AUC insulin than apneic men with low-waist circumference. Accordingly, apneic men with high-waist circumference had higher hepatic insulin resistance as reflected by higher HOMA-resistance index, and lower global insulin sensitivity as reflected by lower insulin sensitivity index of Matsuda (derived from OGTT. The sleep structure and the apnea-hypopnea index were not different between the two groups. However, apneic men with high-waist circumference presented with lower mean nocturnal oxyhemoglobin (SpO2. In the 38 men, waist circumference and mean nocturnal SpO2 were inversely correlated (r = -0.43, p = 0.011 and were both associated with plasma glucose/insulin homeostasis indices: the higher the waist circumference, the lower the mean nocturnal SpO2, the lower the insulin-sensitivity. Finally, in multivariable regression model, mean nocturnal SpO2 and not waist circumference was associated with insulin-resistance. CONCLUSION: Thus, excess abdominal adiposity in non obese apneic men was associated with a deteriorated insulin-sensitivity that could be driven by a more severe nocturnal hypoxemia.

    Obesity is one of the most significant contributors to the development of type 2 diabetes mellitus. Tissue-specific glucocorticoids regulated by 11β-hydroxysteroid dehydrogenase enzyme (11β-HSD) type 1 are involved in central obesity and obesity-related comorbidities. Moderate downregulation of 11β-HSD1 can attenuate insulin insensitivity and the impairment of glucose-stimulated insulin secretion. Some of the beneficial effects of 11β-HSD1 inhibition may be mediated, at least in part, through inactivation of tissue-specific glucocorticoid action related to insulin signaling mechanisms, alleviation of abnormal cytokine profile and the improvement of β-cell function. Thus, 11β-HSD1 is a promising target for the treatment and prevention of type 2 diabetes mellitus with obesity. Copyright © 2017 Southern Society for Clinical Investigation.

  11. Changing perspectives in pre-existing diabetes and obesity in pregnancy: maternal and infant short- and long-term outcomes.

    2014-08-01

    Climbing obesity rates in women have propelled the increasing prevalence of type 2 diabetes mellitus (T2DM) in pregnancy, and an increasing number of women with type 1 diabetes mellitus (T1DM) are also affected by obesity. Increasing recognition that an intrauterine environment characterized by obesity, insulin resistance, nutrient excess, and diabetes may be fueling the obesity epidemic in children has created enormous pressure to re-examine the conventional wisdom of our current approaches. Compelling data in pregnancies complicated by diabetes, in particular those accompanied by insulin resistance and obesity, support a fetal programming effect resulting in increased susceptibility to metabolic disease for the offspring later in life. Recent data also underscore the contribution of obesity, lipids, and lesser degrees of hyperglycemia on fetal fat accretion, challenging the wisdom of current gestational weight gain recommendations with and without diabetes. The risks of adverse pregnancy outcomes in T2DM are at least as high as in T1DM and there remains controversy about the ideal glucose treatment targets, the benefit of different insulin analogues, and the role of continuous glucose monitoring in T1DM and T2DM. It has become unmistakably evident that achieving optimal outcomes in mothers with diabetes is clearly impacted by ideal glycemic control but goes far beyond it. The intrauterine metabolic environment seems to have long-term implications on the future health of the offspring so that the effectiveness of our current approaches can no longer be simply measured by whether or not maternal glucose values are at goal.

    Background Both smoking and diabetes can increase the risk and influence the manifestations and outcomes of tuberculosis (TB). It is not clear whether the influence of smoking on pulmonary TB differs between non-diabetic and diabetic patients. Herein, we assessed the manifestations and outcomes of TB in relation to smoking in both diabetic and non-diabetic TB patients. Methodology/Principal Findings All diabetic culture-positive pulmonary TB patients notified from 2005–2010 at three teaching hospitals in Taiwan were enrolled. A culture-positive pulmonary TB patient without DM who was notified to the health authority immediately prior to each diabetic TB patient was selected for comparison. The 972 patients in this study cohort included 365 (37.6%) non-diabetic non-smokers, 149 (15.3%) non-diabetic smokers, 284 (29.2%) diabetic non-smokers, and 174 (17.9%) diabetic smokers. The adjusted relative risk of a pretreatment positive smear for a smoker compared with a non-smoker was 2.19 (95% CI 1.38–3.47) in non-diabetic patients and 2.23 (95% CI 1.29–3.87) in diabetic culture-positive pulmonary TB patients. The adjusted relative risk for a positive smear among diabetic smokers was 5.61 (95% CI 3.35–9.41) compared with non-diabetic non-smokers. Smoking was significantly associated with an increased frequency of bilateral lung parenchyma involvement (AdjOR 1.84, 95% CI 1.16–2.93), far-advanced pulmonary TB (AdjOR 1.91, 95% CI 1.04–3.50), cavitary lesions (AdjOR 2.03, 95% CI 1.29–3.20), and unfavorable outcomes of TB (AdjOR 2.35, 95% CI 1.02–5.41) in non-diabetic patients. However, smoking was not associated with cavitary lung parenchyma lesions regarding the location, number or size of the cavity in diabetic TB patients. Conclusions/Significance Smoking and diabetes have joint effects on a pretreatment positive smear. Diabetic smokers had more than a 5-fold increased risk of a pretreatment positive smear than did non-diabetic non-smokers, indicating

    Full Text Available Diabetes and obesity are two common human disorders that affecting human health and invite various diseases and disorders in normal body functions. These diseases are very common worldwide. Diabetes occurs when high blood sugar levels develop. This happens when body can’t make and use all of the insulin it needs to blood sugar normally to keep blood sugar levels as normal as possible to control diabetes. Diabetic patients will need to follow a diet plan, do exercise and possibly take insulin injections. As part of eating plan, health care provider, and dietitian may ask to limit the amount of carbohydrates eat each day. Low-calorie sweeteners are one easy tool to help for follow eating plan. Obesity is more susceptible and often been associated with frequent ingestion of high energy food in high amount and high intake of sugars such as fermentable sugars such as sucrose, fructose, glucose, and maltose. Both diseases are may be genetically or due to hormonal imbalances. High energy sweeteners may causes caries in the teeth particularly susceptible to the children. Increased calorie intake associated with sugars and carbohydrates, especially when associated with physical inactivity, has been implicated in obesity. Fortunately, low calorie artificial and natural alternatives of sugars have been developed as alternatives to fermentable sugars and have shown promise in these health issues. Although there are only few artificial sweeteners (saccharin, aspartame, acesulfam potassium, sucralose, cyclamate that have been approved as food additives by the Food and Drug Administration and additional other low-caloric sweeteners (sugar alcohols, neotame, stevia, erythritol, xylitol, tagatose that have FDA-generally recognized as safe. Given the health impact of sugars and other carbohydrates, professionals should be aware of the marketed available low caloric sweeteners and both their benefits and potential risks.

    Full Text Available Abstract Background Our aim was to analyze the relationship between abdominal obesity and general obesity, with subclinical atherosclerosis, arterial stiffness and wave reflection in healthy, diabetics and hypertensive subjects. Methods A cross-sectional descriptive study was made of 305 individuals (diabetics 32.8%, hypertensive subjects 37.0% and healthy individuals 30.2%. Measurements: Body mass index (BMI, waist circumference (WC, body fat percentage (BFP and waist/height ratio (WHtR. Arterial stiffness was assessed according to pulse wave velocity (PWV, intima-media thickness of the common carotid artery (C-IMT, augmentation index (central and peripheral, ankle-brachial index (ABI, and central and peripheral pulse pressure. Results WC and WHtR showed a positive correlation to PWV and C-IMT in the studied groups. After adjusting for age, gender, high sensitivity c-reactive protein, serum glucose and the presence of diabetes, hypertension, smoking, dyslipidemia, antidiabetic drugs, lipid-lowering drugs, and atherosclerotic plaques, it was seen that for every 0.1 point increase in WHtR, and for every cm increase in WC, the PWV increased 0.041 and 0.029 m/sec, and C-IMT increased 0.001 mm and 0.001 mm, respectively. Conclusions The measures of abdominal obesity (WHtR and WC correlates better than BMI and BFP with arterial stiffness evaluated by PWV, and with subclinical atherosclerosis evaluated by C-IMT, independently of the presence of diabetes or hypertension.

    Factors associated with increased intra-abdominal pressure such as chronic cough, morbid obesity, and constipation may be related to pelvic floor dysfunction. In this study, we compared anorectal manometry values and clinical data of class II and III morbidly obese patients referred to bariatric surgery with that of non-obese patients. We performed a case-matched study between obese patients referred to bariatric surgery and non-obese patients without anorectal complaints. The groups were matched by age and gender. Men and nulliparous women with no history of abdominal or anorectal surgery were included in the study. Anorectal manometry was performed by the stationary technique, and clinical evaluation was based on validated questionnaires. Mean age was 44.8 ± 12.5 years (mean ± SD) in the obese group and 44.1 ± 11.8 years in the non-obese group (p = 0.829). In the obese group, 65.4% of patients had some degree of fecal incontinence. Mean squeeze pressure was significantly lower in obese than in non-obese patients (155.6 ± 64.1 vs. 210.1 ± 75.9 mmHg, p = 0.004), and there was no significant difference regarding mean rest pressure in obese patients compared to non-obese ones (63.7 ± 23.1 vs. 74.1 ± 21.8 mmHg, p = 0.051). There were no significant differences in anorectal manometry values between continent and incontinent obese patients. The prevalence of fecal incontinence among obese patients was high regardless of age, gender, and body mass index. Anal squeeze pressure was significantly lower in obese patients compared to non-obese controls.

    To perform a systematic review of the effect of interaction between Melanocortin-4 receptor (MC4R) single nucleotide polymorphisms and diet on the development of obesity and Type 2 diabetes. Environmental factors, such as nutrient intakes or feeding behaviours, can modulate the association of polymorphism in the MC4R gene with obesity and Type 2 diabetes mellitus. A systematic literature search was conducted in the PubMed, Scopus and Google Scholar databases, with a combination of the following keywords: Diet*, nutr*, melanocortin receptor, melanocortin 4 receptor and MC4R. To assess the quality of observational studies, we used a 12-item quality checklist, derived from the STREGA statement. A total of 14 articles were selected based on the inclusion and exclusion criteria. Consumption of highly salty foods and adherence to a Mediterranean dietary pattern can modulate the association between MC4R polymorphisms and the risk of obesity or Type 2 diabetes. Despite the highly contradictory results of intervention studies, after short-term lifestyle interventions, children with variant alleles of MC4R single nucleotide polymorphisms can lose more body weight, compared with non-carriers, although they may have difficulty in maintaining this weight loss in the long-term. To interpret the results of studies on adults, we need further studies. The interaction between MC4R genes with dietary factors plays a significant role in the development of obesity or Type 2 diabetes phenotypes. Early detection of MC4R risk alleles in individuals and modification of their diet based on these results could be an efficient strategy to prevent obesity or diabetes in these subgroups. © 2015 Diabetes UK.

    Previous studies have shown that androgenic alopecia is associated with metabolic syndrome and diabetes. However, the detailed mechanism whereby diabetes causes alopecia still remains unclear. We focused on the inflammatory response that is caused by diabetes or obesity, given that inflammation is a risk factor for hair loss. Inducible nitric oxide synthase (iNOS) is known to be upregulated under conditions of acute or chronic inflammation. To clarify the potential role of iNOS in diabetes-related alopecia, we generated obese diabetic iNOS-deficient (ob/ob; iNOS-KO mice). We observed that ob/ob; iNOS-KO mice were potentiated for the transition from telogen (rest phase) to anagen (growth phase) in the hair cycle compared with iNOS-proficient ob/ob mice. To determine the effect of nitric oxide (NO) on the hair cycle, we administered an iNOS inhibitor intraperitoneally (compound 1400 W, 10 mg/kg) or topically (10% aminoguanidine) in ob/ob mice. We observed that iNOS inhibitors promoted anagen transition in ob/ob mice. Next, we administered an NO donor (S-nitrosoglutathione, GSNO), to test whether NO has the telogen elongation effects. The NO donor was sufficient to induce telogen elongation in wild-type mice. Together, our data indicate that iNOS-derived NO plays a role in telogen elongation under the inflammatory conditions associated with diabetes in mice. Copyright © 2018 The Authors.

    Many skin lesions are associated with diabetes mellitus (DM) type 1 or 2, due to the use of antidiabetics or to metabolic and endocrine disorders caused by this disease. Necrobiosis lipoidica (NL) occurs more frequently in patients with DM. Painful ulcerations may occur on NL areas in about 20-25% of the cases and usually they are related to trauma. We present the case of a teenager, male, 17-year-old, having NL with multiple plaques, some of them spontaneously ulcerated after about 33 months of onset. He is known with type 1 DM from 2.5 years and the NL preceding the diagnosis of diabetes mellitus with about six months, presented erythematous-infiltrative skin plaques, some ulcerated for about three months, interesting both shins. Based on clinical, histopathological and paraclinical examinations, we established the following diagnoses: ulcerated NL, type 1 DM, moderate mixed dyslipidemia, class I obesity; commissural candidiasis, juvenile acne. Under treatment with Pentoxifyllinum, Sulodexidum, Ketotifenum and topical therapy with 0.2% Hyaluronic acid two months later, we have managed to heal two of the three ulcerated plaques and of the third has become superficial. We applied 0.5% Fluocortolonum on non-ulcerated plaques recording an improvement after two weeks of treatment. NL is a skin disease with a predilection for the shins, more frequent in patients with diabetes and is a part of palisading granulomatous dermatitis, which leads to skin atrophy. NL is found in the 0.3-1.2% of diabetic patients and is rare in children with diabetes (0.006%). It is more common in the patients with type 1 DM. The onset is in the third decade in diabetic patients and in the fourth decade in non-diabetics. There is no consensus concerning the treatment of NL, and the results are often modest. Antiplatelet agents, corticosteroids (local and general), immunomodulatory drugs, cyclins, wide synthetic antipaludics, heparin, Thalidomide are used. NL treatment is very difficult

    To describe the number of Mexican adults with undiagnosed diabetes and arterial hypertension and their association with obesity. The study included a sub-sample of 6 613 subjects aged 20 years or more who participated in the 2006 National Health and Nutrition Survey (ENSANUT 2006). Subjects with a previous diagnosis of diabetes or hypertension (n=1 861) were excluded. Prevalences and standard errors were estimated, taking into account the complex sample design. 6.4 million adults have obesity and undiagnosed impaired fasting glucose. Almost two million more have fasting glucose levels diagnostic for diabetes. As for arterial blood pressure, 5.4 million adults had prehypertension. Another 5.4 million adults had blood pressure levels suggestive of probable hypertension. A total of 21.4 million Mexican adults with obesity had at least one further component of the metabolic syndrome. A large proportion of adults with obesity-related metabolic comorbidities remains undiagnosed in Mexico.

    The study investigated the effects of type 2 diabetes mellitus on salivary flow and composition in humans compared to healthy sex and age matched controls. Forty adult human subjects divided into 20 diabetic and 20 non-diabetic healthy subjects were included. Saliva samples were collected and analysed for glucose, total protein, calcium, sodium, potassium, chloride and bicarbonate. Salivary flow rate was also determined. The results showed that salivary glucose and potassium levels were significantly higher (p = 0.01 and 0.002 respectively) in diabetic patients compared with non-diabetic participants. It was also found that the diabetic patients had significant reduction in salivary flow rate when compared with non-diabetic individuals. In contrast, there was no significant difference in levels of total protein, Na+, Ca++, Cl- and HCO3- between the two groups. These results suggest that some oral diseases associated with diabetes mellitus may be due to altered levels of salivary glucose, potassium and flow.

    Type 1 diabetes mellitus (T1DM) is a major disease affecting a large number of young patients. In the recent years, retinal vascular imaging has provided an objective assessment of vascular health in patients with T1DM. Our study aimed to review the current literature on retinal vascular parameters in young patients with T1DM in order to understand the following: (i) How retinal vessels are affected in T1DM (ii) How such vascular changes can be predictive of future diabetic microvascular complications METHODS: We performed a systematic review and extracted relevant data from 17 articles. We found significant correlations between retinal vessel changes and diabetes-related risk factors (eg, hypertension, hyperlipidemia, and obesity), diabetes-related features (eg, diabetes duration and glycemic control), and diabetes-related microvascular complications (eg, diabetic retinopathy, nephropathy, and neuropathy). Our findings suggest that retinal microvasculature is associated with both disease severity and complications in young patients with T1DM. © 2016 John Wiley & Sons Ltd.

    South Asians living in Western countries have shown higher prevalence of cardiovascular disease and related non-communicable diseases as compared to the local populations. The aim of this study was to compare the general health status and prevalence of myocardial infarction (MI), diabetes, high blood pressure, overweight, obesity, and fruit and vegetable intake between Pakistani immigrants in the Netherlands and local Amsterdam population. A health survey was conducted in 2012-2013 among Pakistanis in the Netherlands. Results were compared with a health survey conducted among inhabitants of Amsterdam in 2012. One hundred and fifty-four Pakistanis from four big cities of the Netherlands and 7218 inhabitants of Amsterdam participated. The data for Amsterdam population were weighed on the basis of age, gender, city district, marital status, ethnicity and income level while the data for Pakistanis were weighed on the basis of age and gender to make both data-sets representative of their general population. Pakistanis reported a high prevalence of MI (3.3%), diabetes (11.4%), high blood pressure (14.4%), overweight (35.5%) and obesity (18.5%) while Amsterdam population reported the prevalence as 2.5% for MI, 6.8% for diabetes, 15.3% for high blood pressure, 28.1% for overweight and 11.1% for obesity. Pakistanis had a significantly higher level of MI (OR = 2.71; 95% CI: 1.19-6.14), diabetes (OR = 4.41; 95% CI: 2.66-7.33) and obesity (OR = 2.51; 95% CI: 1.53-4.12) after controlling for age, sex and educational level with Amsterdam population as the reference group. Pakistanis showed a higher intake of fruit and fruit juice as compared to Amsterdam population though the latter showed a higher intake of cooked vegetables. Higher prevalence of MI, diabetes and obesity among Pakistanis than Amsterdam population indicates the need for health scientists and policy-makers to develop interventions for tackling non-communicable diseases and its determinants among

  8. Vitamin D: link between osteoporosis, obesity, and diabetes?

    Vitamin D (1,25(OH)2D3) is a steroid hormone that has a range of physiological functions in skeletal and nonskeletal tissues, and can contribute to prevent and/or treat osteoporosis, obesity, and Type 2 diabetes mellitus (T2DM). In bone metabolism, vitamin D increases the plasma levels of calcium and phosphorus, regulates osteoblast and osteoclast the activity, and combats PTH hypersecretion, promoting bone formation and preventing/treating osteoporosis. This evidence is supported by most clinical studies, especially those that have included calcium and assessed the effects of vitamin D doses (≥800 IU/day) on bone mineral density. However, annual megadoses should be avoided as they impair bone health. Recent findings suggest that low serum vitamin D is the consequence (not the cause) of obesity and the results from randomized double-blind clinical trials are still scarce and inconclusive to establish the relationship between vitamin D, obesity, and T2DM. Nevertheless, there is evidence that vitamin D inhibits fat accumulation, increases insulin synthesis and preserves pancreatic islet cells, decreases insulin resistance and reduces hunger, favoring obesity and T2DM control. To date, there is not enough scientific evidence to support the use of vitamin D as a pathway to prevent and/or treat obesity and T2DM.

    The obesity-hypoventilation syndrome (OHS), or alveolar hypoventilation in the obese, has been described initially as the "Pickwickian syndrome". It is defined as chronic alveolar hypoventilation (PaO2 or =45 mmHg) in obese patients (body mass index>30 kg/m2) who have no other respiratory disease explaining the hypoxemia-hypercapnia. The large majority of obese subjects are not hypercapnic, even in case of severe obesity (>40 kg/m2). There are three principal causes, which can be associated, explaining alveolar hypoventilation in obese subjects: high cost of respiration and weakness of the respiratory muscles (probably the major cause), dysfunction of the respiratory centers with diminished chemosensitivity, long-term effects of the repeated episodes of obstructive sleep apneas observed in some patients. The role of leptin (hormone produced by adipocytes) in the pathogenesis of this syndrome, has been recently advocated. OHS is generally observed in subjects over 50 years. Its prevalence has markedly increased in recent years, probably due to the present "epidemic" of obesity. The diagnosis is often made after an episode of severe respiratory failure. Comorbidities, favored by obesity, are very frequent: systemic hypertension, left heart diseases, diabetes. OHS must be distinguished from obstructive sleep apnea syndrome (OSAS) even if the two conditions are often associated. OSAS may be absent in certain patients with OHS (20% of the patients in our experience). On the other hand obesity may be absent in certain patients with OSAS. Losing weight is the "ideal" treatment of OHS but in fact it cannot be obtained in most patients. Nocturnal ventilation (continuous positive airway pressure and mainly bilevel non invasive ventilation) is presently the best treatment of OHS and excellent short and long-term results on symptoms and arterial blood gases have been recently reported.

    Full Text Available Abstract Background Both obesity and type 2 diabetes are associated with hypovitaminosis D. The aims of this study were to investigate the association of serum 25-hydroxy vitamin D (25(OH D and parathyroid hormone (PTH concentration with body mass index (BMI in type 2 diabetic patients compared to control subjects and their predicting role in obesity. Methods This cross-sectional study was conducted on 200 subjects (100 type 2 diabetics and 100 healthy controls. Concentration of 25(OH D, calcium, phosphorous, parathyroid hormone (PTH, fasting blood glucose, HbA1c, serum insulin, homeostasis model assessment of insulin resistance (HOMA-IR was determined in the fasting samples. Anthropometric measurements including body mass index (BMI were also measured. Results Eighty-five percent of type 2 diabetics and 79% of healthy subjects were suffering from vitamin D deficiency or insufficiency. Serum concentration of 25(OH D (22.08 ± 15.20 ng/ml (r = −0.11, P = 0.04 and calcium (8.94 ± 0.59 mg/dl (r = −2.25, P = 0.04 has significant statistically with BMI in type 2 diabetic patients. Serum concentration of PTH has non-significantly associated with BMI in diabetic patients and healthy subjects. Conclusion Serum levels of vitamin D inversely and PTH positively are associated with BMI after adjusted for age, gender and serum calcium in both type 2 diabetic patients and healthy subjects. These associations were statistically significant for serum concentration of vitamin D and calcium only in diabetic patients. So the status of vitamin D is considered as an important factor in type 2 diabetic patients.

    Full Text Available Caroline M ApovianMedicine and Pediatrics, Boston University School of Medicine; Nutrition and Weight Management Center; and Section of Endocrinology, Diabetes and Nutrition, Department of Medicine, Boston Medical Center, Boston, MA, USAAbstract: Obesity increases the risk for developing type 2 diabetes mellitus (T2DM and this in turn correlates with an elevated probability of long-term diabetes complications once diabetes is established. Interventions aimed at lowering weight via changes in diet and lifestyle have repeatedly been shown to improve glycemic control in patients with T2DM and even to reverse early disease. Weight gain, a potential side effect of treatment for patients with T2DM, is also an important concern, and it has been noted that weight increases associated with antidiabetes therapy may blunt cardiovascular risk reductions achieved by decreasing blood glucose. Among older agents, metformin and acarbose have the lowest risk for weight gain, while sulfonylureas, meglitinides, and thiazolidinediones are all associated with weight increases. Clinical trial results have also consistently demonstrated that treatment with glucagon-like peptide-1 receptor agonists and amylin lowers weight, and that dipeptidyl peptidase-4 inhibitors are weight neutral in patients with T2DM. Conventional human insulin formulations are known to increase weight in patients with T2DM. However, some insulin analogs, particularly insulin detemir, have lower liability for this adverse event. The use of both pharmacologic and surgical therapies aimed at treating obesity rather than lowering blood glucose have the potential to improve glycemic control and even resolve T2DM in some patients.Keywords: bariatric, diabetes, incretin, insulin, obesity, oral antidiabetes agents

    Objective: To study the correlation between Non-high-density lipoprotein and low-density lipoprotein cholesterol in patients with Type 2 diabetes mellitus and the proportion of patients achieving Adult Treatment Panel III recommended goals. Methods: The cross sectional study was conducted at the Diabetic Clinic, Aga Khan University Hospital, Karachi. Data of Type 2 diabetes mellitus patients who attended the clinic between 2007 and 2011 was reviewed. All Type 2 diabetic patients of either gender with fasting lipid profile irrespective of taking lipid lowering therapy were included. Type-1 DM, gestational diabetes, type 2 diabetes patients with pregnancy and those with incomplete data were excluded. Correlation between the low-density lipoprotein and Non- high-density lipoprotein was assessed by applying Cramer V and phi. Proportion of patients achieving Adult Treatment Panel III recommended goals was checked. Multivariable regression was done to identify common factors associated with elevated Non- high-density lipoprotein cholesterol. Results: A total of 1352 patients fulfilling the eligibility criteria were included in the study. Mean age of the patients was 54.5+-11.3 years; 797 (59%) were males; 1122 (83%) had Body Mass Index above 25; and 1016 (75%) had HbA1c >7%. Mean Non-high-density lipoprotein cholesterol was 129+-42mg/dl. Mean low-density lipoprotein cholesterol was 100+-37mg/dl. Both low-density lipoprotein 130mg/dl (p 100mg/dl was independently associated with having Non-high-density lipoprotein cholesterol >130mg/dl (Adjusted Odds Ratio 38.6; 95% Confidance Interval 28.1-53.1). Similarly, age 130 mg/dl (Adjusted Odds Ratio 1.6; 95% Confidance Interval = 1.01 - 2.3). Whereas having obesity Body Mass Index >25 was 3.6 times more associated to have Non-high-density lipoprotein >130mg/dl (Adjusted Odds Ratio 3.6; 95% Confidance Interval = 1.6-7.7).

    2012-01-01

    Full Text Available Obesity and type 1 diabetes (T1DM are the two most common conditions of altered metabolism in children and adolescents. In both, similar long-term cardiovascular complications are known to occur, mediated in large part by underlying inflammatory and oxidative processes whose biochemical details remain relatively unclear. Through a series of experiments in these patient populations, over the last decade our laboratory has clarified a number of key issues in this field. Interestingly, while obese and type 1 diabetic children often differed in the specific type and magnitude of molecular alterations, in both groups a clear exaggeration of inflammatory and oxidative activation was detected when compared to healthy, age-matched controls. Our main findings include definition of resting and exercise-induced cytokine patterns and leukocyte profiles, patterns of activation of immune cells in vitro, and correlation of the magnitude of observed alterations with severity of obesity and quality of glycemic control. Further, we have identified a series of alterations in growth factor profiles during exercise that parallel inflammatory changes in obese children. This paper offers a concise overview of the salient results from this decade-long research effort.

    Obesity and aging have been independently associated with altered required friction during walking, but it is unclear how these factors interact to influence the likelihood of slipping. Therefore, the purpose of this study was to determine whether there are differences related to obesity and aging on required friction during overground walking. Fourteen older non-obese, 11 older obese, 20 younger non-obese, and 20 younger obese adults completed walking trials at both a self-selected and hurried speed. When walking at a hurried speed, older obese men walked at a slower gait speed and exhibited lower frictional demands compared both to older non-obese men and to younger obese men. No differences in required friction were found between non-obese and obese younger adults. These results suggest that the increased rate of falls among obese or older adults is not likely due to a higher risk of slip initiation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To examine the relationship between habitual dietary patterns and the metabolic syndrome (MetS) in women and to identify foci for preventive nutrition interventions. Dietary patterns, nutrient intake, cardiovascular disease (CVD), and MetS risk factors were characterized in 1615 Framingham Offspring-Spouse Study (FOS) women. Dietary pattern subgroups were compared for MetS prevalence and CVD risk factor status using logistic regression and analysis of covariance. Analyses were performed overall in women and stratified on obesity status; multivariate models controlled for age, apolipoprotein E (APOE) genotypes, and CVD risk factors. Food and nutrient profiles and overall nutritional risk of five non-overlapping habitual dietary patterns of women were identified including Heart Healthier, Lighter Eating, Wine and Moderate Eating, Higher Fat, and Empty Calories. Rates of hypertension and low high-density lipoprotein levels were high in non-obese women, but individual MetS risk factor levels were substantially increased in obese women. Overall MetS risk varied by dietary pattern and obesity status, independently of APOE and CVD risk factors. Compared with obese or non-obese women and women overall with other dietary patterns, MetS was highest in those with the Empty Calorie pattern (contrast p value: p<0.05). This research shows the independent relationship between habitual dietary patterns and MetS risk in FOS women and the influence of obesity status. High overall MetS risk and the varying prevalence of individual MetS risk factors in female subgroups emphasize the importance of preventive nutrition interventions and suggest potential benefits of targeted behavior change in both obese and non-obese women by dietary pattern.

    There is growing recognition that obesity is common and represents a significant detriment to the health of companion animals in a manner similar to that by which it is affecting the human population. As is the case for other species, obesity appears to promote insulin resistance in horses and it is through this pathophysiological process that many of the adverse medical consequences of obesity are being characterized. Equine medical conditions that have been described in the context of obesity and insulin resistance differ from those in humans. Chronic human conditions that have been attributed to obesity and insulin resistance, such as atherosclerosis and diabetes mellitus, are rarely described in obese horses. Significant current interest is centered on the recognition that insulin resistance plays a role in the pathogenesis of laminitis, a potentially severe and debilitating cause of lameness in the equine species. Other equine medical conditions that are more likely in obese, insulin-resistant individuals include hyperlipemia (hepatic lipidosis) and developmental orthopedic disease (osteochondrosis). Pituitary pars intermedia dysfunction (equine Cushing's syndrome) represents another common endocrinopathic condition of older horses associated with insulin resistance. This review presents an introductory overview of the present understanding of obesity and insulin resistance and how these conditions may be associated with disease conditions in horses. © Diabetes Technology Society

    Today's epidemic of obesity and diabetes poses challenges to health care similar to those facing soldiers who return with postdeployment mental health issues. These include geographic barriers, social stigma, and the need for behavioral change. Researchers at University of Southern California's Institute for Creative Technologies are adapting their extensive experience in technological solutions for training to techniques that can aid veterans in need. These techniques show promise for concerns in the growing crisis of "diabesity." Virtual reality (VR) has already demonstrated itself as an impactful treatment method for several behavioral and mental health domains. Virtual worlds, the successor technology of original VR, inherited many of its predecessor's strengths but also presents the new affordances of accessibility, social connectivity, and avatar usage, which pave the way toward future treatment options on a broader scale. © 2011 Diabetes Technology Society.

    The incidence of diabetes in developing countries in Asia has increased over the last few years. The economic development is radically changing the lifestyle of the younger generation who prefer to embrace the western lifestyle of eating high calorie fast food with minimal physical exercise. Previously, the rate of diabetes was very low but it is increasing at an alarming rate in the developing countries in Asia. Admittedly, there is paucity of literature on the prevalence of patients with type-1 diabetes in Asian developing countries due to lower field surveys and lack of quantitative data. Few contributing factors such as body mass index (BMI) and its relation with obesity and diabetes, energy dense diet, excessive caloric intake, sedentary behaviors, lifestyle and family history, gene and genomewide association of diabetes, genes and gene polymorphisms are being discussed especially with regard to the Asian population. Dynamics of the diabetes and obesity was depicted for the population of Asian developing countries with special emphasis on China and India. Diabetes has become widespread among the low-income communities. Hence, it is necessary to develop appropriate healthcare policies in order to mitigate this rampant epidemic before it is too late.

  2. Method of Detection of Well-Differentiated Thyroid Cancers in Obese and Non-Obese Patients.

    Full Text Available The incidence of well-differentiated thyroid cancer (WDTC is increasing rapidly. Many authors feel that this increase is due to over-diagnosis and that one of the contributing factors is the increasing use of various imaging studies. The rate of obesity has also been increasing in the United States. It has been suggested that patients with an increased body mass index (BMI kg/m2 have a higher incidence of WDTC than patients with normal BMI. One might hypothesize that thyroid nodules are more difficult to palpate in obese patients and that as more cancers are detected by imaging the apparent rate of increase in WDTC in obese patients would appear to be greater than in non-obese patients. This study was undertaken to evaluate this hypothesis by determining if there is any difference in the way thyroid cancers are initially detected in obese and non-obese patients.The medical records of all 519 patients with a postoperative diagnosis of WDTC who underwent thyroidectomy at NYU Langone Medical Center from January 1, 2007 through August 31, 2010 by the three members of NYU Endocrine Surgery Associates were reviewed. Patients were divided into Non-obese (BMI<30 kg/m2 and Obese (BMI≥30 kg/m2 groups. Patients were also divided by the initial method of detection of their tumor into Palpation, Imaging, and Incidental groups.The final study group contained 270 patients, 181(67% of whom were in the Non-obese Group and 89(33% were in the Obese Group. In the Non-obese group, 81(45% of tumors were found by palpation, 72(40% were found by imaging, and 28(16% were found incidentally. In the Obese group, 40(45% were found by palpation, 38(43% were found by imaging, and 11(12% were found incidentally. These differences were not statistically significant (p-value 0.769.We show that BMI does not play a role in the method of initial detection in patients with WDTC. This suggests that the prevalence of WDTC detected by imaging is not an artifact caused by an

    The prevalent raise of type 2 diabetes (T2D) around the globe, are creating higher risk for cardiovascular diseases (CVDs) and increasing strain on each country's health care budget in the world. Microalbuminuria has appeared as a key parameter in diabetic patients. Microalbuminuria is also related to increased cardiovascular morbidity in people who are non-obese diabetic. Some studies have suggested that consumption of symbiotic foods might help improve the metabolic profile, inflammatory factors and biomarkers of oxidative stress. The aim of trial was to determine the effect of symbiotic supplementation on glycemic control, lipid profiles and microalbuminuria in non-obese T2D. In this randomized, double-blind, clinically controlled trial, 70 patients with T2D (28 females, 42 males) were randomly divided into two groups ( n  = 35 for each group). The symbiotic group (SG) consumed 500 mg/d of symbiotic supplementations containing probiotics (Lactobacillus family, Bifidobacterium family, Streptococus thermophilus), Prebiotics (Fructo oligosaccharide) and B group vitamins (1 mg), lactose (0.5 mg), malt-dextrin, magnesium saturate and the placebo group (PG) consumed capsules filled with row starch and also B group vitamins (1 mg), lactose (0.5 mg), malt-dextrin, magnesium saturate for 9 weeks. Fasting blood glucose (FBG), hemoglobin A1c (HbA1c), blood lipid profiles, 24-h dietary recalls, and anthropometric measurements were measured at the baseline and at the end of trial. SPSS software, version 16 was used to test the data and the results were expressed as mean ± standard deviation. Paired samples T-Test were used to compare continuous variables within groups. Comparison between different groups was performed through two independent samples T-Test. In the absence of normal distribution, the comparison between the groups was made using non-parametric Wilcoxon on signed ranks and Mann-Whitney tests. P values Symbiotic supplementation decreased

    Background  Diabetes and obesity are more prevalent amongst psoriasis patients as is disturbance of the innate immune system. GLP-1 analogue therapy considerably improves weight and glycaemic control in people with type 2 diabetes and its receptor is present on innate immune cells. Objective  We aimed to determine the effect of liraglutide, a GLP-1 analogue, on psoriasis severity. Methods  Before and after 10 weeks of liraglutide therapy (1.2 mg subcutaneously daily) we determined the psoriasis area and severity index (PASI) and the dermatology life quality index (DLQI) in seven people with both psoriasis and diabetes (median age 48 years, median body mass index 48.2 kg\\/m(2) ). We also evaluated the immunomodulatory properties of liraglutide by measuring circulating lymphocyte subset numbers and monocyte cytokine production. Results  Liraglutide therapy decreased the median PASI from 4.8 to 3.0 (P = 0.03) and the median DLQI from 6.0 to 2.0 (P = 0.03). Weight and glycaemic control improved significantly. Circulating invariant natural killer T (iNKT) cells increased from 0.13% of T lymphocytes to 0.40% (P = 0.03). Liraglutide therapy also effected a non-significant 54% decrease in the proportion of circulating monocytes that produced tumour necrosis factor alpha (P = 0.07). Conclusion  GLP-1 analogue therapy improves psoriasis severity, increases circulating iNKT cell number and modulates monocyte cytokine secretion. These effects may result from improvements in weight and glycaemic control as well as from direct immune effects of GLP-1 receptor activation. Prospective controlled trials of GLP-1 therapies are warranted, across all weight groups, in psoriasis patients with and without type 2 diabetes.

    Full Text Available Summary Objective: The main goal of this work was to produce a review of educational strategies to prevent diabetes, hypertension, and obesity. Method: PubMed database was consulted using combined descriptors such as [Prevention], [Educational Activities], [Diabetes], [Hypertension], and [Obesity]. Data from randomized trials published between 2002 and 2014 were included in spreadsheets for analysis in duplicate by the reviewers. Results: A total of 8,908 articles were found, of which 1,539 were selected about diabetes mellitus (DM, n=369, arterial systemic hypertension (ASH, n=200, and obesity (OBES, n=970. The number of free full text articles available was 1,075 (DM = 276, ASH = 118 and OBES = 681. In most of these studies, demographic characteristics such as gender and age were randomized, and the population mainly composed by students, ethnic groups, family members, pregnant, health or education professionals, patients with chronic diseases (DM, ASH, OBES or other comorbidities. Group dynamics, physical activity practices, nutritional education, questionnaires, interviews, employment of new technologies, people training and workshops were the main intervention strategies used. Conclusion: The most efficient interventions occurred at community level, whenever the intervention was permanent or maintained for long periods, and relied on the continuous education of community health workers that had a constant interference inside the population covered. Many studies focused their actions in children and adolescents, especially on students, because they were more influenced by educational activities of prevention, and the knowledge acquired by them would spread more easily to their family and to society.

    The prevalence of severe obesity among children and young adults has increased over the past decade. Although the prevalence of cardiometabolic risk factors is relatively low among children and young adults who are overweight or obese, those with more severe forms of obesity may be at greater risk. We performed a cross-sectional analysis of data from overweight or obese children and young adults 3 to 19 years of age who were included in the National Health and Nutrition Examination Survey from 1999 through 2012 to assess the prevalence of multiple cardiometabolic risk factors according to the severity of obesity. Weight status was classified on the basis of measured height and weight. We used standard definitions of abnormal values for total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, triglycerides, blood pressure, glycated hemoglobin, and fasting glucose and report the prevalence of abnormal values in children and young adults according to weight status. Among 8579 children and young adults with a body-mass index at the 85th percentile or higher (according to the Centers for Disease Control and Prevention growth charts), 46.9% were overweight, 36.4% had class I obesity, 11.9% had class II obesity, and 4.8% had class III obesity. Mean values for some, but not all, cardiometabolic variables were higher with greater severity of obesity in both male and female participants, and the values were higher in male participants than in female participants; for HDL cholesterol, the mean values were lower with greater severity of obesity. Multivariable models that controlled for age, race or ethnic group, and sex showed that the greater the severity of obesity, the higher the risks of a low HDL cholesterol level, high systolic and diastolic blood pressures, and high triglyceride and glycated hemoglobin levels. Severe obesity in children and young adults was associated with an increased prevalence of cardiometabolic risk factors

Time-series analysis (2001-2012) using annual provincial health care (N ≈ 3 million per year) and biennial Canadian Community Health Survey (N ≈ 5500 per cycle) data for adults (30-64 years) living in Southern Ontario cities. Neighborhood walkability derived from a validated index, with standardized scores ranging from 0 to 100, with higher scores indicating more walkability. Neighborhoods were ranked and classified into quintiles from lowest (quintile 1) to highest (quintile 5) walkability. Annual prevalence of overweight, obesity, and diabetes incidence, adjusted for age, sex, area income, and ethnicity. Among the 8777 neighborhoods included in this study, the median walkability index was 16.8, ranging from 10.1 in quintile 1 to 35.2 in quintile 5. Resident characteristics were generally similar across neighborhoods; however, poverty rates were higher in high- vs low-walkability areas. In 2001, the adjusted prevalence of overweight and obesity was lower in quintile 5 vs quintile 1 (43.3% vs 53.5%; P walkable neighborhoods (absolute change, 5.4% [95% CI, 2.1%-8.8%] in quintile 1, 6.7% [95% CI, 2.3%-11.1%] in quintile 2, and 9.2% [95% CI, 6.2%-12.1%] in quintile 3). The prevalence of overweight and obesity did not significantly change in areas of higher walkability (2.8% [95% CI, -1.4% to 7.0%] in quintile 4 and 2.1% [95% CI, -1.4% to 5.5%] in quintile 5). In 2001, the adjusted diabetes incidence was lower in quintile 5 than other quintiles and declined by 2012 from 7.7 to 6.2 per 1000 persons in quintile 5 (absolute change, -1.5 [95% CI, -2.6 to -0.4]) and 8.7 to 7.6 in quintile 4 (absolute change, -1.1 [95% CI, -2.2 to -0.05]).

    The rising rates, high prevalence, and adverse consequences of obesity and diabetes call for new approaches to the complex behaviors needed to prevent and manage these conditions. Virtual reality (VR) technologies, which provide controllable, multisensory, interactive three-dimensional (3D) stimulus environments, are a potentially valuable means of engaging patients in interventions that foster more healthful eating and physical activity patterns. Furthermore, the capacity of VR technologies to motivate, record, and measure human performance represents a novel and useful modality for conducting research. This article summarizes background information and discussions for a joint July 2010 National Institutes of Health – Department of Defense workshop entitled Virtual Reality Technologies for Research and Education in Obesity and Diabetes. The workshop explored the research potential of VR technologies as tools for behavioral and neuroscience studies in diabetes and obesity, and the practical potential of VR in fostering more effective utilization of diabetes- and obesity-related nutrition and lifestyle information. Virtual reality technologies were considered especially relevant for fostering desirable health-related behaviors through motivational reinforcement, personalized teaching approaches, and social networking. Virtual reality might also be a means of extending the availability and capacity of health care providers. Progress in the field will be enhanced by further developing available platforms and taking advantage of VR’s capabilities as a research tool for well-designed hypothesis-testing behavioral science. Multidisciplinary collaborations are needed between the technology industry and academia, and among researchers in biomedical, behavioral, pedagogical, and computer science disciplines. Research priorities and funding opportunities for use of VR to improve prevention and management of obesity and diabetes can be found at agency websites (National

    High-quality diets play an important role in diabetes prevention. Appropriate dietary adherence can improve insulin sensitivity and glycemic control, and thus contribute to lifestyle improvement. However, previous research suggests that dietary adherence is arguably among the most difficult cornerstones of diabetes management. The objectives of this study are (1) to estimate whether and to what extent individuals diagnosed with diabetes show significant differences in diet quality [healthy eating index (HEI)] compared to healthy individuals, (2) to quantify whether and to what extent diabetics experience significantly higher outcomes of body mass index (BMI), and (3) to estimate whether and to what extent dietary supplementation impacts diabetes patient's diet quality and/or BMI outcomes. We use data from the 2007-2008 U.S. National Health and Nutrition Examination Survey (NHANES). The NHANES is the primary, randomized, and nationally representative survey used to assess the health and nutritional status in the U.S. We apply propensity score matching (PSM) to account for selection bias and endogeneity between self-reported diet and health behavir (treatment) and BMI outcomes. We control for an individual's BMI as to capture the impact of past dietary behavior in its impact on HEI. Matching results suggest that regular dietary supplement consumption is associated with significant lower BMI outcomes of almost 1 kg/m(2). The close relationship between diabetes and obesity has been at the center of the diet-health policy debate across Canada and the U.S. Knowledge about this linkage may help to improve the understanding of the factors that impact dietary choices and their overall health outcomes, which may lead to a more efficient and effective promotion of dietary guidelines, healthy food choices, and targeted consumer health and lifestyle policies.

    Full Text Available The growing prevalence of metabolic diseases, such as obesity and diabetes, are putting a high strain on global healthcare systems as well as increasing the demand for efficient treatment strategies. More than 360 million people worldwide are suffering from type 2 diabetes and, with the current trends, the projection is that 10% of the global adult population will be affected by 2030. In light of the systemic properties of metabolic diseases as well as the interconnected nature of metabolism, it is necessary to begin taking a holistic approach to study these diseases. Human genome-scale metabolic models (GEMs are topological and mathematical representations of cell metabolism and have proven to be valuable tools in the area of systems biology. Successful applications of GEMs include the process of gaining further biological and mechanistic understanding of diseases, finding potential biomarkers and identifying new drug targets. This review will focus on the modeling of human metabolism in the field of obesity and diabetes, showing its vast range of applications of clinical importance as well as point out future challenges.

    Obesity and metabolic syndrome represent major public health problems, and are the biggest preventable causes of death worldwide. Obesity is the leading risk factor for type 2 diabetes mellitus (T2DM), cardiovascular diseases and non-alcoholic fatty liver disease. Obesity-associated insulin resistance, which is characterized by reduced uptake and utilization of glucose in muscle, adipose and liver tissues, is a key predictor of metabolic syndrome and T2DM. With increasing prevalence of obesity in adults and children, the need to identify and characterize potential targets for treating metabolic syndrome is imminent. Emerging evidence from animal models, clinical studies and cell lines studies suggest that protein tyrosine phosphatase 1B (PTP1B), an enzyme that negatively regulates insulin signaling, is likely to be involved in the pathways leading to insulin resistance. PTP1B is tethered to the cytosolic surface of endoplasmic reticulum (ER), an organelle that is responsible for folding, modification, and trafficking of proteins. Recent evidence links the disruption of ER homeostasis, referred to as ER stress, to the pathogenesis of obesity and T2DM. PTP1B has been recognized as an important player linking ER stress and insulin resistance in obese subjects. This review highlights recent advances in the research related to the role of PTP1B in signal transduction processes implicated in pathophysiology of obesity and type 2 diabetes, and focuses on the potential therapeutic exploitation of PTP1B inhibitors for the management of these conditions.

    Pigment epithelium-derived factor (PEDF) is a member of the serpin family secreted by adipocytes. Plasma PEDF is increased in obese children and adults. Adults with type 2 diabetes mellitus (T2DM) have higher circulating PEDF but there are no reports in children with T2DM. To compare PEDF concentration in children with T2DM to normal weight and obese children without T2DM and determine associations with anthropometric or serum factors. Participants were 34 obese children with T2DM diagnosed by American Diabetes Association (ADA) criteria, 61 normal weight [body mass index (BMI) 25-75 percentile] and 63 obese (BMI ≥ 95 percentile) children of age 8-18 yr. Plasma PEDF was measured in fasting plasma samples. Anthropometric, serum, and body composition (dual-energy x-ray absorptiometry, DXA) data were obtained for each subject to identify potential predictor variables. PEDF was 55% higher (p = 0.001) in the T2DM group compared with normal weight children, but did not differ from obese children. In the T2DM group, fat mass and lean mass both individually predicted PEDF (r² = 0.22 and 0.17, p = 0.02 and p obese groups, therefore, obesity, rather than diabetes, may account for the higher PEDF in children with T2DM compared with normal weight children. PEDF was positively associated with both lean mass and fat mass both of which may contribute to the circulating level of the protein, and potentially to PEDF's association with insulin resistance in obese children with and without diabetes. © 2014 John Wiley & Sons A/S.

    Full Text Available The health behaviours of pregnant women with very severe obesity are not known, though these women are at high risk of pregnancy complications. We carried out a prospective case-control study including 148 very severely obese (BMI >40 kg/m2 and 93 lean (BMI <25 kg/m2 pregnant women. Diet, physical activity, smoking, alcohol and folic acid consumption were assessed by questionnaire in early and late (16 and 28 weeks gestation pregnancy. Circulating levels of iron, vitamin B12 and folate and other essential trace elements and minerals were measured in a subset at each time point. The findings biochemically confirmed that very severely obese women consumed diets that were energy-rich but poor in essential micronutrients. A third of all women met physical activity recommendations for pregnancy. A third of very severely obese women and two thirds of lean women took folic acid supplements prior to pregnancy. Very severely obese women were more likely to smoke but less likely to drink alcohol than lean women (all p < 0.05. Women with very severe obesity have low self-reported intakes and circulating levels of essential micronutrients in pregnancy and few follow current recommendations for pregnancy nutrition and lifestyle. These high-risk women represent a group to target for education about health behaviours prior to and during pregnancy.

    Non-proliferative diabetic retinopathy is the early stage of diabetic retinopathy. Automatic detection of non-proliferative diabetic retinopathy is significant for clinical diagnosis, early screening and course progression of patients. This paper introduces the design and implementation of an automatic system for screening non-proliferative diabetic retinopathy based on color fundus images. Firstly, the fundus structures, including blood vessels, optic disc and macula, are extracted and located, respectively. In particular, a new optic disc localization method using parabolic fitting is proposed based on the physiological structure characteristics of optic disc and blood vessels. Then, early lesions, such as microaneurysms, hemorrhages and hard exudates, are detected based on their respective characteristics. An equivalent optical model simulating human eyes is designed based on the anatomical structure of retina. Main structures and early lesions are reconstructed in the 3D space for better visualization. Finally, the severity of each image is evaluated based on the international criteria of diabetic retinopathy. The system has been tested on public databases and images from hospitals. Experimental results demonstrate that the proposed system achieves high accuracy for main structures and early lesions detection. The results of severity classification for non-proliferative diabetic retinopathy are also accurate and suitable. Our system can assist ophthalmologists for clinical diagnosis, automatic screening and course progression of patients.

    Hair analysis has been demonstrated to accurately reflect exposure to drug abuse, environmental toxins and exogenous hormones. We tested the feasibility of measuring cortisol and testosterone in hair of healthy and obese subjects. A modified immunoassay (ELISA) originally developed for saliva was used. Hair, urine and blood samples were collected from young non-obese and obese patients. Perceived stress (PSS) was measured using a validated questionnaire. There was no difference in PSS between non-obese and obese subjects. Hair cortisol levels were significantly correlated with weight (r = 0.27, p cortisol levels did not correlate with age or urinary cortisol. There was a negative correlation between hair testosterone and age (r = -0.47, p cortisol over hair testosterone (C/T) was higher in the obese group than in the young non-obese group. The C/T ratio correlated positively with age (r = 0.56, p cortisol levels increase, while hair testosterone levels decrease with obesity. The hair C/T ratio was significantly correlated with age, BMI and waist circumference better than hair cortisol or testosterone alone. As hair collection is non-invasive and is not influenced by moment-to-moment variations, the measurement of hormones in hair is a useful tool in research and possibly clinical practice. © Georg Thieme Verlag KG Stuttgart · New York.

    Household devices (e.g., television, car, computer) are common in high income countries, and their use has been linked to obesity and type 2 diabetes mellitus. We hypothesized that device ownership is associated with obesity and diabetes and that these effects are explained through reduced physical activity, increased sitting time and increased energy intake. We performed a cross-sectional analysis using data from the Prospective Urban Rural Epidemiology study involving 153,996 adults from high, upper-middle, lower-middle and low income countries. We used multilevel regression models to account for clustering at the community and country levels. Ownership of a household device increased from low to high income countries (4% to 83% for all 3 devices) and was associated with decreased physical activity and increased sitting, dietary energy intake, body mass index and waist circumference. There was an increased odds of obesity and diabetes with the ownership of any 1 household device compared to no device ownership (obesity: odds ratio [OR] 1.43, 95% confidence interval [CI] 1.32-1.55; diabetes: OR 1.38, 95% CI 1.28-1.50). Ownership of a second device increased the odds further but ownership of a third device did not. Subsequent adjustment for lifestyle factors modestly attenuated these associations. Of the 3 devices, ownership of a television had the strongest association with obesity (OR 1.39, 95% CI 1.29-1.49) and diabetes (OR 1.33, 95% CI 1.23-1.44). When stratified by country income level, the odds of obesity and diabetes when owning all 3 devices was greatest in low income countries (obesity: OR 3.15, 95% CI 2.33-4.25; diabetes: OR 1.97, 95% CI 1.53-2.53) and decreased through country income levels such that we did not detect an association in high income countries. The ownership of household devices increased the likelihood of obesity and diabetes, and this was mediated in part by effects on physical activity, sitting time and dietary energy intake. With

    This study compared the level of prejudice against obese individuals (obesity bias) among final-year health and non-health students, and associated obesity education. Cross-sectional online survey of 479 final-year students (292 health and 187 non-health) from Griffith University, Australia. Implicit and explicit obesity bias was measured using validated tools, and perceived obesity education ranked from "none" to "excellent." Data were analyzed quantitatively using analysis of variance and independent sample t tests. Statistical significance was set at P Students' mean age was 26.2 ± 7.6 years and body mass index was 23.2 ± 4.7 kg/m(2). Health and non-health students exhibited significant levels of obesity bias. Non-health students were more likely to suggest that obese individuals lacked willpower (P = .03). Students' self-reported obesity education varied considerably. Those who reported a higher level of genetics-related obesity education were less likely to believe that obese individuals were "bad" (P = .002) or to show concern about putting on weight (P = .01). Obesity bias exists in health students in Australia and is similar to non-health students' obesity bias levels. Students' self-reported genetics-related obesity education may be associated with obesity bias. Modifications to existing health curricula should be considered to reduce obesity bias among future health professionals. Copyright © 2014 Society for Nutrition Education and Behavior.

    Obesity and alcohol drinking are associated with metabolic syndrome. However, few studies show the relationship between alcohol drinking and metabolic syndrome according to varying degrees of obesity. This study aimed to determine the association between alcohol drinking and metabolic syndrome in obese and non-obese Korean male adults. This cross-sectional study included 5,867 males aged ≥ 20 years who were examined at the Soonchunhyang University health promotion center during June 2008-December 2010. The subjects were divided into non-obese (body mass index [BMI] 14 drinks/week) groups. The subjects were also categorized into binge drinking and non-binge drinking groups. To obtain odds ratios (ORs) for metabolic syndrome, binary logistic regression analysis was performed. The overall metabolic syndrome prevalence was 27.3% (12.8%, non-obese group; 50.4%, obese group). After adjusting for age, physical activity, and smoking, in the non-obese group, the OR for heavy drinking with binge drinking (reference: nondrinking) was 1.56 (95% confidence interval [CI] = 1.12-2.18), with a significant increase in metabolic syndrome prevalence. In the obese group, the OR for heavy drinking with binge drinking was 1.42 (95% CI = 1.07-1.88), showing a significant increase in metabolic syndrome prevalence ( P metabolic syndrome. Thus, both non-obese and obese males should restrict their alcohol intake and not indulge in binge drinking.

    Fructose-containing added sugars, such as sucrose and high-fructose corn syrup, have been experimentally, epidemiologically, and clinically shown to be involved in the current epidemics of obesity and diabetes. Here we track this history of intake of sugar as it relates to these epidemics. Key experimental studies that have identified mechanisms by which fructose causes obesity and diabetes are reviewed, as well as the evidence that the uricase mutation that occurred in the mid-Miocene in ancestral humans acted as a "thrifty gene" that increases our susceptibility for fructose-associated obesity today. We briefly review recent evidence that obesity can also be induced by nondietary sources of fructose, such as from the metabolism of glucose (from high-glycemic carbohydrates) through the polyol pathway. These studies suggest that fructose-induced obesity is driven by engagement of a "fat switch" and provide novel insights into new approaches for the prevention and treatment of these important diseases. © 2017 American Society for Nutrition.

    The exact cause of the obesity epidemic remains unknown; however, both environmental and genetic factors are involved. People at risk of developing obesity include children with type 1 diabetes mellitus (T1DM), which in turn increases their cardiovascular disease risk. Here, we discuss the clinical and genetic factors influencing weight in patients with T1DM. In children with T1DM, the presence of obesity depends mainly on sex, metabolic control, and disease duration. However, genetic factors, including the fat mass and obesity-associated (FTO) gene, are also associated with body weight. Indeed, children with the FTO gene rs9939609 obesity-risk allele (homozygous = AA or heterozygous = AT) are predisposed to a higher body mass index and have a greater risk of being overweight or obese. However, in this review, we show that FTO gene polymorphisms only have a small effect on body weight in children, much weaker than the effect of clinical factors. The association between FTO gene polymorphisms and body weight is only statistically significant in children without severe obesity. Moreover, other genetic factors had no effect on weight in patients with T1DM, and further research involving larger populations is required to confirm the genetic basis of diabetes and obesity. Therefore, identifying the clinical features of children with T1DM, such as their initial body mass index, sex, metabolic control, and disease duration, will still have the strongest effect on reducing risk factors for cardiovascular diseases. Physicians should pay close attention to modifiable elements of these relationships, for example, metabolic control and energy and insulin intake, when caring for patients with T1DM.
