    Iodine deficiency and obesity are worldwide-occurring health problems. Our purpose was to investigate the relationship between morbid obesity and iodine status, including subjects who lost weight after bariatric surgery. Ninety morbidly obese women, 90 women with at least 18 months follow-up after bariatric surgery, and 45 healthy non-obese women were recruited. Urinary iodine concentration (UIC) was measured in a spot urinary sample and expressed as the iodine-to-creatinine ratio. Obese women showed a significantly lower UIC in comparison with non-obese women (96.6 (25.8-267.3) vs. 173.3 (47.0-493.6) μg/g; p iodine status (46.6 vs. 83.3 %, p risk factor to iodine deficiency, almost in women. Whether more obese population needs to be considered as a vulnerable group and whether bariatric surgery can reverse iodine deficiency still remain to be elucidated.

    Ghrelin is an endogenous appetite stimulant that may have a role in ovarian function. Women with polycystic ovary syndrome have anovulation and frequently weight management issues; however the associations between ghrelin and hormonal markers in polycystic ovary syndrome have not been well studied. In order to characterize the association between total ghrelin levels and ovarian function and the possible modification of this relationship by obesity, we examined total ghrelin levels and anti-mullerian hormone, total testosterone, and insulin in obese and non-obese women with and without polycystic ovary syndrome. Total ghrelin levels were lower in obese women with polycystic ovary syndrome (n = 45) compared to obese controls (n = 33) (p = 0.005), but similar in non-obese women with polycystic ovary syndrome (n = 20) compared to non-obese controls (n = 21) (p = NS). In the obese polycystic ovary syndrome group, anti-mullerian hormone was associated with ghrelin levels independent of age, insulin, and total testosterone (p = 0.008). There was no association between total ghrelin and anti-mullerian hormone levels in non-obese women with polycystic ovary syndrome, non-obese controls, or obese controls (p = NS). Our results provide evidence for a potential relationship between ghrelin and ovarian function in obese women with polycystic ovary syndrome that was not observed in non-obese women with polycystic ovary syndrome or controls.

    Full Text Available BACKGROUND: Hyperandrogenism (HA has been linked with several components of metabolic syndrome (MetS. Few studies in Asian women have evaluated the important risk factors for and prevalence of MetS according to PCOS subtype. In this study, we investigated differences in metabolic parameters and the prevalence of MetS in two major phenotypic subgroups of PCOS in Korea. Furthermore, we investigated the relationship between HA-associated parameters and MetS. MATERIALS AND METHODS: This cross-sectional observational study was conducted from May 2010 to December 2011 in Korea. A total of 837 females with PCOS, aged 15-40, were recruited from Departments of Obstetrics and Gynecology at 13 hospitals. Of those, 700 subjects with either polycystic ovaries (PCO+HA+oligomenorrhea/amenorrhea (O or PCO+O were eligible for this study. MetS was diagnosed according to the modified National Cholesterol Education Program (NCEP Adult Treatment Panel (ATP III guidelines and the International Diabetes Federation (IDF criteria. RESULTS: MetS was more prevalent in the PCO+HA+O group (19.7% than in the PCO+O (11.9% group. There were statistically significant trends for an increased risk of MetS in the PCO+HA+O group compared to the PCO+O group. After adjustment for age, the odds ratio of MetS was 2.192 in non-obese subjects with PCO+HA+O compared to those with PCO+O, whereas the risk of MetS was not different in obese patients. Multivariate logistic regression analysis showed that high free androgen index and low sex hormone-binding globulin were significantly associated with MetS in non-obese women with PCOS, with odds ratios of 4.234 (95% CI, 1.893-9.474 and 4.612 (95% CI, 1.978-10.750, respectively. However, no associations were detected between MetS and SHBG and FAI in obese PCOS subjects. CONCLUSIONS: Our results indicate that HA and its associated parameters (FAI and SHBG are significantly associated with MetS in non-obese PCOS subjects, whereas this association

    Full Text Available Our study assessed the validity of self-reported restless sleep (SRRS in measuring sleep efficiency and the degree to which these measures differed depending on obesity status in older women. Data were from 100 participants enrolled in the Kingston Senior Women Study. Participants recorded SRRS for 7 consecutive nights. Sleep efficiency measures were recorded nightly through actigraphy. Repeated-measures multilevel logistic analysis was used. Mean sleep efficiency was 87% (SE = 1.09, SRRS occurred in 37% (SE = 3 of nights. Obesity status moderated the association between sleep efficiency and SRRS (odds ratio [OR] = 1.08; 95% confidence interval [CI] = [1.02, 1.14] when controlling for age, medication intake, and depressive symptoms. Higher sleep efficiency reduced the odds of SRRS in non-obese women, but no association was shown in obese women. The lack of correspondence between objective and subjective measures in obese women suggests that SRRS may not be as indicative of sleep quality in obese compared with non-obese older women.

    Full Text Available CONTEXT (BACKGROUND: Polycystic ovary syndrome (PCOS is one of the most common endocrinopathy of premenopausal women and is a most frequent cause of infertility. There are more stringent reports of cardiovascular events and infrequent investigations of lipid levels in lean PCOS. AIMS: To assess the cardiac autonomicity using Heart Rate Variability (HRV parameters and metabolic risk with serum lipid parameters among ideal and lean weight PCOS patients. Settings and Design: case control study. 24 classical PCOS diagnosed by Rotterdam 2003 Diagnostic criteria and were ideal and lean as per WHO criter ia and 24 BMI matched, age matched normally menstruating women served as study participants. Methods and Material: 5 min of Electrocar - diogram (ECG was taken which was evaluated for HRV. Power spectral analysis was done to calculate the time and frequency domain measures of HRV. Fasting serum lipid profile was done. Statistical analysis: Independent sample‘t’ test was used. RESULTS: The results of the present study showed that cardiac autonomic innervations can be affected in lean and ideal weight PCOS wit h increased sympathetic and decreased parasympathetic components of HRV. As a result, sympathetic to parasympathetic ratio may increase in PCOS. Fasting blood sugar was also increased. Of the lipid parameters total cholesterol and LDL - C was increased. Othe r parameters were not altered. CONCLUSION: This study gives a solid and strong evidence of altered cardiac autonomic activity and unfavorable metabolic profile, which are the important risk factors for cardiovascular disease even in lean and ideal weight P COS. Our data suggest that all PCOS patients should undergo periodic screening for normal cardiac activity and lipid profiles irrespective of obesity.

  12. Effects of Metformin Combined with Cyproterone Acetate on Clinical Features, Endocrine and Metabolism of Non-obese Women with Polycystic Ovarian Syndrome

    2005-01-01

    In order to explore the effects of metformin combined with cyproterone acetate (CPA) on the clinical features, endocrine and metabolism of the patients with polycystic ovarian syndrome (PCOS), 50 cases of non-obese PCOS were randomly subjected to CPA (CPA treatment group, n=25) and CPA+metformin (n= 25) treatment for 6 months. Before and after treatment the body mass index (BMI), waist: hip ratio (WHR), ovarian volume, serum gonadotrophin, androgen and sex hormone-binding globulin (SHBG) levels, and fasting lipid, glucose and insulin levels were measured. The results showed that all of the parameters in two groups were similar before treatment. After treatment for 6 months in the CPA+ metformin group, BMI and WHR were significantly decreased, while insulin sensitivity was significantly decreased as compared with those before treatment. In CPA group, no significant changes were found before and after treatment. Combined use of CPA and metformin could result in the reduction of serum androstenedione and increases of serum SHBG levels as compared with the CPA treatment alone. It was concluded that combined use of CPA and metformin could improve the insulin sensitivity, and further suppress the hyperandrogenism in non-obese women with PCOS.

  13. A cross-sectional study to assess any possible linkage of C/T polymorphism in CYP17A1 gene with insulin resistance in non-obese women with polycystic ovarian syndrome

    Full Text Available Background & objectives: Insulin resistance (IR is a major confounding factor in polycystic ovarian syndrome (PCOS irrespective of obesity. Its exact mechanism remains elusive till now. C/T polymorphism in the -34 promoter region of the CYP17 gene is inconsistently attributed to elucidate the mechanism of IR and its link to hyperandrogenemia in obese PCOS patients. In the present study we aimed to evaluate any association of this polymorphism with IR in non-obese women with PCOS. Methods: Polymorphism study was performed by restriction fragment length polymorphism (RFLP analysis of the Msp A1 digest of the PCR product of the target gene in 75 PCOS cases against 73 age and BMI matched control women. Serum testosterone, BMI and HOMA-IR (homeostatic model of assessment-insulin resistance were analyzed by standard techniques. A realistic cut-off value for the HOMA-IR was obtained through receiver operating characteristic (ROC curve for exploring any possible link between IR and T/C polymorphism in the case group. Results: Significant increases in serum testosterone and HOMA-IR values were observed among the case group (P<0.001 without any significant elevation in BMI and FBG compared to controls. Cut-off value for IR in the PCOS patients was 1.40 against a maximum sensitivity of 0.83 and a minimum false positivity of 0.13. The analysis revealed an inconclusive link between the C/T polymorphic distribution and insulin resistant case subjects. Interpretation & conclusions: The results showed that CYP17A1 gene was not conclusively linked to either IR or its associated increased androgen secretion in non-obese women with PCOS. We propose that an increased sensitivity of insulin on the ovarian cells may be the predominant reason for the clinical effects and symptoms of androgen excess observed in non-obese PCOS patients in our region.

    There is scarce information about the factors associated with estrogen receptors (ER) at menopause. In 113 volunteers pre- and post-menopausal healthy women, grouped as with and without obesity, estrogen receptors-alpha and -beta, and progesterone receptor (PR) were measured by immunohistochemistry in skin punch biopsies obtained from the external gluteal area. In pre-menopausal women, biopsies and a blood sample were performed between days 7 and 14 of the cycle. Serum hormone levels were measured by immunoradiometric assay or radioimmunoassay. After menopause, ER and PR amounts decreased significantly. At pre-menopause, obese women had lower PR levels than non obese (P<.006). In the post-menopausal group, obese women showed higher ER-alpha (P<.03) and ER-beta (P<.02) levels than the non obese group. In the analysis of factors associated with the amount of steroid receptors for the total group, log[ER-alpha], log[ER-beta], and log[PR] were associated with age (P<.002, <.005, and <.004, respectively). The log[ER-alpha] was also associated with log[FSH] (P<.0008); meanwhile, the log[PR] showed a marginal correlation with log[FSH]. In pre-menopausal women no factor associated with any of the three receptors was found. In post-menopausal women log[ER-alpha] was associated with log[estrone] and log[DHEAS] (P<.003 and <.02, respectively). log[PR] was associated with BMI (P<.002), years since menopause (P<.05), and log[DHEAS] (P<.003). We concluded that ER and PR diminish sharply at post-menopause. At this stage the amount of receptors depends on several factors such as BMI, years since menopause, and androgen precursors.

    Exposure to fine particulate matter (PM) is a recognized risk factor for elevated blood pressure (BP) and cardiovascular disease in adults, and this prospective cohort study was undertaken to evaluate whether gestational exposure to PM(2.5) has a prohypertensive effect. We measured personal exposure to fine particulate matter (PM(2.5)) by personal air monitoring in the second trimester of pregnancy among 431 women, and BP values in the third trimester were obtained from medical records of prenatal care clinics. In the general estimating equation model, the effect of PM(2.5) on BP was adjusted for relevant covariates such as maternal age, education, parity, gestational weight gain (GWG), prepregnancy BMI, environmental tobacco smoke (ETS), and blood lead level. Systolic blood pressure (SBP) increased in a linear fashion across a dosage of PM(2.5) and on average augmented by 6.1 mm Hg (95% CI, 0.6-11.6) with log unit of PM(2.5) concentration. Effects of age, maternal education, prepregnancy BMI, blood lead level, and ETS were insignificant. Women with excessive gestational weight gain (>18 kg) had higher mean SBP parameters by 5.5 mmHg (95% CI, 2.7-8.3). In contrast, multiparous women had significantly lower SBP values (coeff. = -4.2 mm Hg; 95% CI, -6.8 to -1.6). Similar analysis performed for diastolic blood pressure (DBP) has demonstrated that PM(2.5) also affected DBP parameters (coeff. = 4.1; 95% CI, -0.02 to 8.2), but at the border significance level. DBP values were positively associated with the excessive GWG (coeff. = 2.3; 95% CI, 0.3-4.4) but were inversely related to parity (coeff. = -2.7; 95% CI, -4.6 to -0.73). In the observed cohort, the exposure to fine particulate matter during pregnancy was associated with increased maternal blood pressure.

    Sleep apnea and obesity are strongly associated, and both increase the risk for coronary artery disease. Several cross-sectional studies have reported discrepant results regarding the role obesity plays in the relation between sleep apnea and coronary artery calcium (CAC), a marker of subclinical coronary disease. The aim of the present study was to investigate the association between sleep apnea and the presence of CAC in a community cohort of middle-aged men and women without preexisting cardiovascular disease, stratified by body mass index (0. Sleep apnea was analyzed categorically using the apnea-hypopnea index. The sample was composed of primarily men (61%) and Caucasians (56%), with a mean age of 61 years. The prevalence of CAC was 76%. In participants with body mass indexes <30 kg/m(2) (n = 139), apnea-hypopnea index ≥15 (vs <5) was associated with 2.7-fold odds of having CAC, but the effect only approached significance. Conversely, in participants with body mass indexes ≥30 kg/m(2), sleep apnea was not independently associated with CAC. In conclusion, sleep apnea is independently associated with early atherosclerotic plaque burden in nonobese patients.

    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.

    Aberrant circulating adipokines are considered to be related to the pathological mechanism of polycystic ovary syndrome (PCOS). This study aims to evaluate the relationship between plasma omentin-1 levels, metabolic and hormonal parameters in the setting of non-obese Chinese women with PCOS. This was a case-controlled, cross-sectional study of 153 non-obese (BMIobese control individuals. Levels of plasma omentin-1, fasting blood glucose, insulin and sexual hormones and ovary volume were analyzed in all subjects. Plasma omentin-1 levels of non-obese PCOS individuals were significantly lower than in healthy non-obese controls. Body Mass Index (BMI), homeostasis model of assessment for insulin resistance index (HOMA-IR), levels of testosterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), LH/FSH ratio and ovary volume (OV) were significantly higher in subjects with PCOS than controls. In the HOMA-IR stratified subgroups, PCOS individuals with insulin resistance had lower omentin-1 than those without insulin resistance after BMI adjustment. Omentin-1 was negatively correlated with BMI, HOMA-IR and fasting insulin. Multiple linear regressions revealed that BMI contributed to omentin-1 levels. Ovary volume was negatively correlated to HOMA-IR but had no correlation with omentin-1. Plasma omentin-1 concentrations were decreased in the non-obese PCOS group. Insulin resistance could further decrease plasma omentin-1 in non-obese individuals with PCOS independent of BMI status. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    目的:比较复方醋酸环丙孕酮和螺内醋治疗以高雄激素血症为主要表现的非肥胖型多囊卵巢综合征(PCOS)的临床疗效和对内分泌代谢的影响.方法:按前瞻性随机对照研究方法选择以高雄激素血症为主要表现的非肥胖型PCOS患者80例,按随机化分组方案分为复方醋酸环丙孕酮(EE-CA)组和螺内6a(Sp)组,每组40例,分别口服相应的药物6个月,比较治疗前、后的体质量指数((BMI),腰臀比(WHR)、多毛体征、痤疮程度以及卵巢体积,并测定血清卵泡刺激素(FSH)、黄体生成素(LH)、雌二醇(E2)、泌乳素(PRL),总睾酮(T)、性激素结合球蛋白(SHBG)、硫酸脱氮表雄酮(DHEAS)、空腹血糖(FPG)、空腹胰岛素(FINS)和血脂的水平,记录服药后不良反应.结果:治疗多毛EE-CA和Sp疗效接近((P>0.05); EE-CA组治疗6个月后痤疮评分下降较Sp组作用明显(P0.05). Compared with Sp, EE-CA decreased the acne scores significantly after 6 months of treatment (P<0.05), and was superior in reducing the size of the ovary, decreasing the serum LH level, LH/FSH ratio, FAI, DHEAS and increasing the SHBG level (P<0.05, P<0.01). The FINS, triglyceride and HDL level of EE-CA group were higher than those of Sp group (P<0.05). Conclusion: Both EE-CA and Sp are effective in treating hyperandrogenism of non-obese women with PCOS. EE-CA is superior to Sp in improving hyperandrogenism, however, should be cautious to apply to the patients with high triglyceride; Sp also has good effect on decreasing the T level, and has no significant influence on glucose and lipid metabolism.

    The goal of our study was to determine whether there was a difference in operative outcomes in obese versus non-obese subjects undergoing robotic-assisted hysterectomies of varying levels of difficulty. Secondarily, we sought to analyze the published outcomes between robotic-assisted hysterectomy and total laparoscopic hysterectomy in obese women at each of these levels of difficulty. This was a multi-institutional retrospective cohort study of all patients undergoing robotic-assisted hysterectomy by five gynecologic oncologists at four geographically separate locations from April 2003 to March 2008. The cohort was stratified into obese vs. non-obese groups, and defined surgical outcomes compared between groups, then further divided into three subgroups based on case difficulty level. Univariate analysis and regression analysis using SAS 9.1 was performed. We then conducted a literature search of total laparoscopic hysterectomy outcomes in obese women, dividing the resulting studies into three comparative subgroups based on surgical difficulty levels for comparison with our robotic-assisted hysterectomy results. Our cohort had 228 obese and 323 non-obese subjects. Overall, the obese group had higher blood loss and longer operative time. When further stratified by level of difficulty, obese subjects also had a higher average blood loss and longer operative time in the hysterectomy-alone subgroup. No clinically significant differences in operative outcomes exist between obese and non-obese women when utilizing the da Vinci robotic system to perform a hysterectomy, independent of case difficulty level. More prospective, controlled studies which compare the two surgical approaches of robotic-assisted and laparoscopic hysterectomy approaches are needed.

    AIM: Metformin is the 'drug-of-first-choice' in obese patients with type 2 diabetes mellitus (T2DM) due to its antihyperglycaemic and cardiovascular protective potentials. In non-obese patients with T2DM, insulin secretagogues are empirically used as first choice. In this investigator......-initiated trial, we evaluated the effect of metformin vs. an insulin secretagogue, repaglinide on glycaemic regulation and markers of inflammation and insulin sensitivity in non-obese patients with T2DM. METHODS: A single-centre, double-masked, double-dummy, crossover study during 2 x 4 months involved 96 non-obese......: In non-obese patients with T2DM, overall glycaemic regulation was equivalent with less hypoglycaemia during metformin vs. repaglinide treatment for 2 x 4 months. Metformin was more effective targeting non-glycaemic cardiovascular risk markers related to total and abdominal body fat stores as well...

    Obesity is a chronic disease and has become the most prevalent public health problem worldwide. The impact of obesity on knee is strong and the BMI is correlated with the different alterations. Compare surgical visualization of arthroscopic field in partial meniscectomy in obese and non-obese. Sixty patients were selected, 30 obese and 30 non-obese who underwent arthroscopic partial meniscectomy. The arthroscopic surgical procedures were recorded and analyzed. For the analysis of visualization was used the Johnson's classification (2000). Were analyzed 48 men and 12 women, the average age was 42.9 years with BMI between 21.56 to 40.14 kg/m2. The distribution of visibility of the surgical field according to the classification was: grade 1 - 38/60 (63.3%); grade 2 - 13/60 (21.6%); grade 3 - 6/60 (10%); grade 4 - 3/60 (5%). Knee arthroscopy did not show a significant difference in the visibility of arthroscopic field in obese and non-obese patients. Thus, it should not be indicated as the preferred method of diagnostic evaluation of joint changes in these patients.

    Background: Little research has been conducted on the prevalence of diabetes mellitus in underdeveloped areas in China, especially stratified into obesity and non-obese diabetes. The aim of the present study was to investigate the prevalence and associated factors of non-obese diabetes in an underdeveloped area in South China, Guangxi. Methods: Data derived from the Chinese Health and Nutrition Survey 2010–2012 involved a sample of 3874 adults from Guangxi. Questionnaires and oral glucose-tolerance tests were conducted, and fasting and 2-h glucose levels and serum lipids were measured. Logistic regression analysis was performed to assess associated factors for non-obese diabetes. Results: 68.2% and 62.2% of instances of newly detected diabetes were those of non-obese diabetes based on BMI (NODB) and based on WC (NODW), respectively. The male sex, an age older than 50 years, lower education, hypertension, and hypertriglyceridemia were significantly associated with a higher risk of both NODB and NODW, while some associated factors for NODB were found different from those associated with NODW, and an interaction effect was found to increase the risk of NODW. Conclusions: Our study indicated that non-obese diabetes was highly prevalent in an underdeveloped area of South China. Non-obese diabetes should be considered for increased public attention in these areas. PMID:27706056

    The link between obesity and renal disease is unclear, and there is no consensus as to whether obese individuals are at increased risk for kidney disease after living kidney donation if they otherwise meet acceptance criteria. We retrospectively studied time-zero (implantation) biopsies in 49 obese (body mass index (BMI) > or = 30 kg/m2) and 41 non-obese (BMI < 30 kg/m2) renal donors that met acceptance criteria. We found that our obese donor population had higher systolic blood pressure (P < 0.001 vs non-obese) and higher absolute iothalamate clearance (P = 0.001 vs non-obese) before donation. The obese donors had larger glomerular planar surface area compared to non-obese controls (P = 0.017), and this parameter correlated with patient weight and urinary microalbumin excretion. Detailed examination of the biopsies revealed that although most histologic findings were similar between groups, the obese donors had more tubular dilation (P = 0.01), but less tubular vacuolization (P = 0.02) than the non-obese controls. There was also a trend toward more arterial hyalinosis in the obese patients than controls (P = 0.08). From these data, our studies detected subtle differences in donor organs obtained from obese compared to non-obese individuals. Further studies should be carried out to quantify the long-term impact of these findings.

    In several countries including Japan, people without obesity but with a clustering of metabolic risk factors (MetRFs) were not considered to have the metabolic syndrome (MetS). Here, we examined whether lifestyle characteristics differed between non-obese and obese subjects with or without a clustering of MetRFs. From a population-based cross-sectional study of Japanese subjects aged ≥ 40 years, 1,601 subjects (age: 61.9 ± 10.3 years; 710/891 men/women) were recruited. Physical activity status and daily nutritional intake were estimated using questionnaires. A clustering of MetRFs was defined based on the presence of at least two non-essential risk factors for the diagnosis of the MetS in Japan. Energy intake was not higher in subjects with a clustering of MetRFs compared with those without. Among men, energy expenditure at work was significantly lower in non-obese (9.0 ± 8.2 vs. 11.3 ± 9.3 metabolic equivalents (METs), P = 0.025) and obese (9.0 ± 7.9 vs. 11.6 ± 9.4 METs, P = 0.017) subjects with a clustering of MetRFs than in those without. Multiple logistic regression analysis showed that energy expenditure at work was significantly associated with a clustering of MetRFs after adjusting for possible confounding factors including total energy intake. The ORs (per 1 METs) were 0.970 (95% CI, 0.944-0.997; P = 0.032) in non-obese men and 0.962 (0.926- 0.999; P = 0.043) in obese men. Similar associations were not observed in women. In Japanese males, lower physical activity, but not excessive energy intake, is a risk factor for a clustering of MetRFs independent of their obesity status.

    Adiponectin has insulin-sensitizing, anti-atherogenic, and anti-inflammatory properties, and researchers have recently reported that omega-3 polyunsaturated fatty acid (PUFA) can increase the serum adiponectin concentration, suggesting that dietary factors, such as fish intake, may have an influence on the serum adiponectin concentration. In general, Japanese subjects consume twice as much fish as people in other countries. We hypothesized that incremental change in serum omega-3 PUFA levels by fish intake is an important regulator of serum adiponectin even in Japanese subjects. The aim of this study was to explore the relationship among fish consumption, serum omega-3 PUFA, such as eicosapentaenoic acid (EPA), levels, and serum adiponectin levels. We recruited 17 healthy Japanese volunteers (seven men and 10 women) for an 8-week fish-diet intervention (omega-3 PUFA 3.0 g/day) without affecting total energy intake, and measured serum adiponectin concentration and fatty acid profiles. Fish-diet intervention significantly increased the serum adiponectin concentration in women (from 13.5+/-4.6 to 15.8+/-5.2 microg/mL, p diet intervention (57.3+/-86.6 vs 150.9+/-46.7 microg/mL, p=0.011), suggesting that changes in omega-3 PUFA concentration may explain the different response between sexes. A fish-based diet intervention increased the serum adiponectin concentration in young, non-obese, healthy Japanese female subjects. The increment in serum omega-3 PUFA may regulate the serum adiponectin concentration.

    This pilot study adapted a well-established drug self-administration paradigm to examine the effects of mood induction on the ability to resist high-calorie foods and subsequent food consumption differently in 15 obese individuals (40.0% women, BMI: 35.1±3.70) and 15 non-obese individuals (46.7% women, BMI: 23.0±1.96). Participants completed two laboratory sessions (positive vs. negative mood conditions) consisting of 3-hour food deprivation, followed by mood induction, and a 3-hour ad-lib eating period, where they were asked to choose between favorite high-calorie snacks and monetary reinforcement. Obese individuals were less able to resist eating and increased high-calorie food consumption during the positive mood condition than the negative condition. Non-obese individuals were less able to resist eating during the negative mood condition than the positive condition, but their total consumption was not affected by the mood conditions. In obese individuals, food craving was associated with less ability to resist eating and greater calorie consumption during the negative mood condition. This is the first study to experimentally demonstrate that mood state may increase vulnerability to food consumption by reducing the ability to resist eating. The ability to resist eating may be a novel dimension of eating behaviors that has a significant contribution to understanding mood-eating relationships.

    Full Text Available Background: Increased carotid intima-media thickness (c-IMT is considered a marker of early-onset atherosclerosis and it has been found in obese children and adolescents, but the risk factors associated with this population remain to be elucidated. Objective : To compare and verify the relationship between c-IMT, metabolic profile, inflammatory markers, and cardiorespiratory fitness in obese and non-obese children and adolescents. Method : Thirty-five obese subjects (19 boys and 18 non-obese subjects (9 boys, aged 10-16 years, were included. Anthropometry, body composition, blood pressure, maximal oxygen consumption (VO2max, and basal metabolic rate were evaluated. Serum glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR, blood lipids, C-reactive protein (CRP, and adiponectin were assessed. c-IMT was measured by ultrasound. Results: The results showed that c-IMT, triglycerides, insulin, HOMA-IR, and CRP values were significantly higher in the obese group than in the non-obese group, and high-density lipoprotein cholesterol (HDL-c, adiponectin, and VO2max values were significantly lower in the obese group than in the non-obese group. The c-IMT was directly correlated with body weight, waist circumference, % body fat, and HOMA-IR and inversely correlated with % free fat mass, HDL-c, and VO2max. Conclusions : Our findings show that c-IMT correlates not only with body composition, lipids, insulin resistance, and inflammation but also with low VO2max values in children and adolescents.

    Full Text Available OBJECTIVES: to determine if there are differences in cardiac vagal tone values in non-obese healthy, adult men with and without unfavorable anthropometric characteristics. INTRODUCTION: It is well established that obesity reduces cardiac vagal tone. However, it remains unknown if decreases in cardiac vagal tone can be observed early in non-obese healthy, adult men presenting unfavorable anthropometric characteristics. METHODS: Among 1688 individuals assessed between 2004 and 2008, we selected 118 non-obese (BMI <30 kg/m², healthy men (no known disease conditions or regular use of relevant medications, aged between 20 and 77 years old (42 ± 12-years-old. Their evaluation included clinical examination, anthropometric assessment (body height and weight, sum of six skinfolds, waist circumference and somatotype, a 4-second exercise test to estimate cardiac vagal tone and a maximal cardiopulmonary exercise test to exclude individuals with myocardial ischemia. The same physician performed all procedures. RESULTS: A lower cardiac vagal tone was found for the individuals in the higher quintiles - unfavorable anthropometric characteristics - of BMI (p=0.005, sum of six skinfolds (p=0.037 and waist circumference (p<0.001. In addition, the more endomorphic individuals also presented a lower cardiac vagal tone (p=0.023, while an ectomorphic build was related to higher cardiac vagal tone values as estimated by the 4-second exercise test (r=0.23; p=0.017. CONCLUSIONS: Non-obese and healthy adult men with unfavorable anthropometric characteristics tend to present lower cardiac vagal tone levels. Early identification of this trend by simple protocols that are non-invasive and risk-free, using select anthropometric characteristics, may be clinically useful in a global strategy to prevent cardiovascular disease.

    Childhood obesity is associated with biologic and behavioral characteristics that may impact bone mineral density (BMD) and structure. The objective was to determine the association between obesity and bone outcomes, independent of sexual and skeletal maturity, muscle area and strength, physical activity, calcium intake, biomarkers of inflammation, and vitamin D status. Tibia and radius peripheral quantitative CT scans were obtained in 91 obese (BMI>97th percentile) and 51 non-obese adolescents (BMI>5th and Tibia cortical section modulus and calf muscle area Z-scores were greater in obese participants (1.07 and 1.63, respectively, both pTibia and radius trabecular and cortical volumetric BMD did not differ significantly between groups. Calf muscle area and strength Z-scores, advanced skeletal maturity, and physical activity (by accelerometry) were positively associated with tibia cortical section modulus Z-scores (all ptibia section modulus Z-scores between obese and non-obese participants from 1.07 to 0.28. After multivariate adjustment for greater calf muscle area and strength Z-scores, advanced maturity, and less moderate to vigorous physical activity, tibia section modulus Z-scores were 0.32 (95% CI -0.18, 0.43, p=0.06) greater in obese, vs. non-obese participants. Radius cortical section modulus Z-scores were 0.45 greater (p=0.08) in obese vs. non-obese participants; this difference was attenuated to 0.14 with adjustment for advanced maturity. These findings suggest that greater tibia cortical section modulus in obese adolescents is attributable to advanced skeletal maturation and greater muscle area and strength, while less moderate to vigorous physical activities offset the positive effects of these covariates. The impact of obesity on cortical structure was greater at weight bearing sites.

The objective was to determine the association between obesity and bone outcomes, independent of sexual and skeletal maturity, muscle area and strength, physical activity, calcium intake, bio-markers of inflammation, and vitamin D status. Tibia and radius peripheral quantitative CT scans were obtained in 91 obese (BMI > 97th percentile) and 51 non-obese adolescents (BMI > 5th and <85th percentiles). Results were converted to sex- and race-specific Z-scores relative to age. Cortical structure, muscle area and muscle strength (by dynamometry) Z-scores were further adjusted for bone length. Obese participants had greater height Z-scores (p < 0.001), and advanced skeletal maturity (p < 0.0001), compared with non-obese participants. Tibia cortical section modulus and calf muscle area Z-scores were greater in obese participants (1.07 and 1.63, respectively, both p < 0.0001). Tibia and radius trabecular and cortical volumetric BMD did not differ significantly between groups. Calf muscle area and strength Z-scores, advanced skeletal maturity, and physical activity (by accelerometry) were positively associated with tibia cortical section modulus Z-scores (all p < 0.01). Adjustment for muscle area Z-score attenuated differences in tibia section modulus Z-scores between obese and non-obese participants from 1.07 to 0.28. After multivariate adjustment for greater calf muscle area and strength Z-scores, advanced maturity, and less moderate to vigorous physical activity, tibia section modulus Z-scores were 0.32 (95% CI −0.18, 0.43, p = 0.06) greater in obese, vs. non-obese participants.

    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

    We aimed at determining whether body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) are associated with heart rate recovery (HRR) and to demonstrate which of the three indices of obesity, is the strongest predictor of HRR in apparently healthy non-obese adults. Three hundred and twenty-five subjects aged 18-66 years participated in the study. Anthropometric indices were measured, and subjects performed cycle ergometer exercise at 75-85% maximum heart rate. Heart rate (HR) was measured during the last minute of exercise and in the first minute of post-exercise recovery. A partial correlation test and a multiple linear regression analysis, after adjusting for age and peak oxygen uptake indicated that the best predictors of HRR were BMI in males and WHR in females. The present data suggest that, HRR is independently related to indices of obesity-BMI, WC, and WHR and strengthen the usefulness of these anthropometric indices in predicting cardiovascular risks. In addition, the findings suggest that BMI in men and WHR in women best express the relationship between obesity and cardiovascular risks.

    Full Text Available Polycystic ovary syndrome (PCOS represents the most common cause of anovulatory infertility and affects 6-15% of women of reproductive age. However, the underlying etiology is still poorly understood. In this study, we attempted to examine the association between circulating heat shock protein 70 (Hsp70 concentrations and PCOS in a non-obese Chinese population.Human peripheral blood from 52 patients with PCOS and 57 healthy controls, matched for age and BMI, were analyzed. Women with PCOS were found to have significantly higher fasting insulin (FI levels, as well as Insulin resistance index (HOMA-IR (P < 0.05. Identically, markers of oxidative stress (malondialdehyde (MDA, 8-Hydroxy-desoxyguanosine (8-OHdG, Nitric oxide (NO and inflammation (tumor necrosis factor-alpha (TNF-α, C-reactive protein (CRP were markedly increased when compared to controls (P < 0.05. Elevated serum Hsp70 was positively correlated with IR, oxidative stress and inflammation in PCOS, even after adjustment for age, BMI and gynecologic inflammation (GI. The receiver-operating characteristic curve (ROC analysis yielded notably different discriminative value for PCOS, with or without an addition of Hsp70 (areas under the curves were 0.884 (95% CI 0.822-0.946 vs. 0.822 (95% CI 0.744-0.900; P for difference = 0.015.Increased serum Hsp70 levels are associated with the combination of IR, oxidative stress and low-grade chronic inflammation in PCOS individuals, which provides supportive evidence that Hsp70 plays a key role in the pathogenesis of PCOS. More consequent studies were warranted to confirm the clinical utility of circulating Hsp70, especially in diagnosis and prognosis of PCOS and its long-term health cost.

    Although low testosterone levels in men have been associated with high risk for cardiovascular disease,little is known about the association between male sex hormones and subclinical coronary disease in men with apparently low cardiometabolic risk.This study was performed to investigate the association between male sex hormones and subclinical coronary artery calcification measured as coronary calcium score in non-obese Korean men.We examined the relationship of total testosterone,sex hormone-binding globulin,bioavai lable testosterone and free testosterone with coronary calcium score in 291 non-obese Korean men (mean age:52.8±9.3 years)not having a history of cardiovascular disease.Using multiple linear regression,we evaluated associations between log (sex hormone)levels and log (coronary calcium score) after adjusting for confounding variables in 105 men with some degree of coronary calcification defined as coronary calcium score ≥ 1.In multiple linear regression analysis,bioavailable testosterone was inversely associated with coronary calcium score (P=0.046) after adjusting for age,body mass index,smoking status,alcohol consumption,regular exercise,mean blood pressure,resting heart rate,C-reactive protein,fasting plasma glucose,total cholesterol,triglyceride,high-density lipoprotein (HDL) cholesterol,hypertension medication and hyperlipidemia medication,whereas total testosterone,sex hormone-binding globulin and free testosterone were not (P=0.674,P=0.121 and P=0.102,respectively).Our findings indicate that bioavailable testosterone is inversely associated with the degree of subclinical coronary artery calcification in non-obese men.

    The purpose of this study was to determine whether obese adolescents eat more high-calorie low-nutrient-dense foods than non-obese adolescents. Using a cross-sectional design, 22 non-obese and 21 obese adolescents kept 14-day food records. Records provided estimates of total daily energy intake and caloric intake from five categories of high-calorie, low-nutrient-dense (HC) foods: candy, chips, soda, baked goods, and ice cream. Body composition was determined by 18O dilution and daily energy expenditure by doubly labeled water. Percentage of energy intake reported (%report) was calculated as the ratio of reported energy intake to measured energy expenditure (x 100%). Both groups underreported energy intake, but the percentage reported was significantly greater in the non-obese group (78.2+/-20.5% non-obese vs. 55.5+/-21.8% obese, padolescents. However, total energy intake from all HC foods was higher in the non-obese group than among the obese (617+/-356 kcal/day vs. 362+/-223 kcal/day; padolescents consume a substantial portion of reported calories from HC foods and that obese adolescents do not consume more calories from these foods than non-obese adolescents. These data offer no evidence to support the widespread notion that obese adolescents eat more "junk food" than non-obese adolescents. Health professionals who treat obese adolescents must be aware that the excess calories in their diets may come from a variety of food sources and not solely from high-calorie snack foods.

    Objective This study examined the independent effect of a patient's weight on medical students' attitudes, beliefs, and interpersonal behavior toward the patient, in addition to the clinical recommendations they make for her care. Design Seventy-six clinical-level medical students were randomly assigned to interact with a digital, virtual female patient who was visibly either obese or non-obese. Methods Interactions with the patient took place in an immersive virtual clinical environment (i.e., virtual reality) which allowed standardization of all patient behaviors and characteristics except for weight. Visual contact behavior was automatically recorded during the interaction. Afterward, participants filled out a battery of self-report questionnaires. Results Analyses revealed more negative stereotyping, less anticipated patient adherence, worse perceived health, more responsibility attributed for potentially weight-related presenting complaints, and less visual contact directed toward the obese version of a virtual patient than the non-obese version of the patient. In contrast, there was no clear evidence of bias in clinical recommendations made for the patient's care. Conclusion Biases in attitudes, beliefs, and interpersonal behavior have important implications because they can influence the tone of clinical encounters and rapport in the patient-provider relationship, which can have important downstream consequences. Gaining a clear understanding of the nature and source of weight bias in the clinical encounter is an important first step toward development of strategies to address it. PMID:20820169

    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 periodontitis and presence of retinopathy categorized by body mass index (periodontitis and 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 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.

    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

    No data regards lipoprotein particle profiles in obese and non-obese metabolic health subtypes exist. We characterised lipoprotein size, particle and subclass concentrations among metabolically healthy and unhealthy obese and non-obese adults. Cross-sectional sample of 1834 middle-aged Irish adults were classified as obese (BMI ≥30 kg/m(2)) and non-obese (BMI Lipoprotein size, particle and subclass concentrations were determined using nuclear magnetic resonance (NMR) spectroscopy. Lipoprotein profiling identified a range of adverse phenotypes among the metabolically unhealthy individuals, regardless of BMI and metabolic health definition, including increased numbers of small low density lipoprotein (LDL) (P lipoprotein (HDL) particles (P lipoprotein (VLDL) particles (P lipoprotein related insulin resistance (P lipoprotein particle profiles, irrespective of BMI and metabolic health definition. These findings underscore the importance of maintaining a healthy lipid profile in the context of overall cardiometabolic health. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Non-obese individuals could have metabolic disorders that are typically associated with elevated body mass index (BMI), placing them at elevated risk for chronic diseases. This study aimed to describe the prevalence and distribution of metabolically obese, non-obese (MONO) individuals in Malaysia. We conducted a cross-sectional study involving teachers recruited via multi-stage sampling from the state of Melaka, Malaysia. MONO was defined as individuals with BMI 18.5-29.9 kg/m(2) and metabolic syndrome. Metabolic syndrome was diagnosed based on the Harmonization criteria. Participants completed self-reported questionnaires that assessed alcohol intake, sleep duration, smoking, physical activity, and fruit and vegetable consumption. A total of 1168 teachers were included in the analysis. The prevalence of MONO was 17.7% (95% confidence interval [CI], 15.3-20.4). Prevalence of metabolic syndrome among the normal weight and overweight participants was 8.3% (95% CI, 5.8-11.8) and 29.9% (95% CI, 26.3-33.7), respectively. MONO prevalence was higher among males, Indians, and older participants and inversely associated with sleep duration. Metabolic syndrome was also more prevalent among those with central obesity, regardless of whether they were normal or overweight. The odds of metabolic syndrome increased exponentially from 1.9 (for those with BMI 23.0-24.9 kg/m(2)) to 11.5 (for those with BMI 27.5-29.9 kg/m(2)) compared to those with BMI 18.5-22.9 kg/m(2) after adjustment for confounders. The prevalence of MONO was high, and participants with BMI ≥23.0 kg/m(2) had significantly higher odds of metabolic syndrome.

    Several lines of evidence suggest that the loss of estrogen after menopause may play a role in cognitive declines associated with Alzheimer's disease (AD). In postmenopausal women, the principal source of estrogen is estrone, which is influenced by body mass index (BMI). Increased BMI in postmenopausal women is associated with higher levels of serum estradiol and estrone. We hypothesized that obesity could have a beneficial effect on cognition with advancing age. We compared the performance of healthy nondemented obese and non-obese women with Down syndrome (DS) on a broad spectrum of cognitive tests. Estrone levels were 66.9% higher in obese than in non-obese postmenopausal women, and 136% higher in obese than in non-obese premenopausal women. Obese postmenopausal women performed significantly better than non-obese women on measures of verbal memory and on an omnibus test of neuropsychological function, but did not differ significantly in verbal fluency, language, praxis or visuospatial functioning. Among premenopausal women, there was no difference in cognitive function between obese and non-obese women. Our results support the hypothesis that higher endogenous estrogen levels after menopause are associated with better performance on verbal memory.

    Subjects with impaired glucose tolerance (IGT) are usually overweight and exhibit insulin resistance with a defective compensation of insulin secretion. In this study, we sought to establish the interrelation between insulin secretion and insulin sensitivity after oral glucose in non-obese subjects......). Plasma levels of GLP-1 and GIP increased after oral glucose. Total secretion of these incretin hormones during the 3-hour test did not differ between the 2 groups. However, the 30-minute increase in GLP-1 concentrations was lower in IGT than in NGT (P =.036). We conclude that also in non-obese subjects...

    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.

    Insulin resistance (IR) plays an important pathophysiological role in the development of diabetes, dyslipidemia, hypertension, and cardiovascular disease. Moreover, IR can occur even in non-obese people without diabetes. However, direct detection of IR is complicated. In order to find a simple surrogate marker of IR early in non-obese people, we investigate the association of commonly-used biochemical markers (liver enzymes and lipid profiles) with IR in urban middle-aged and older non-obese Chinese without diabetes. This cross-sectional study included 1 987 subjects (1 473 women). Fasting blood samples were collected for measurement of glucose, insulin, liver enzymes, lipid profiles and creatinine. Subjects whose homeostasis model of assessment-IR (HOMA-IR) index values exceeded the 75th percentile (2.67 for women and 2.48 for men) of the population were considered to have IR. The area under the receiver operating characteristic curve (ROC) was used to compare the power of potential markers in identifying IR. Triglycerides (TG) and ratio of TG to high-density lipoprotein cholesterol (TG/HDL-C) discriminated IR better than other indexes for both sexes; areas under the receiver operating characteristic (ROC) curves (AUC) values were 0.770 (95% confidence interval 0.733-0.807) and 0.772 (0.736-0.809), respectively, for women and 0.754 (0.664-0.844) and 0.756 (0.672-0.840), respectively, for men. To identify IR, the optimal cut-offs for TG and TG/HDL-C ratio were 1.315 mmol/L (sensitivity 74.3%, specificity 71.0%) and 0.873 (sensitivity 70.1%, specificity 73.4%), respectively, for women, and 1.275 mmol/L (sensitivity 66.7%, specificity 74.4%) and 0.812 (sensitivity 75.8%, specificity 69.2%), respectively, for men. TG and TG/HDL-C ratio could be used to identify IR in urban middle-aged and older non-obese Chinese without diabetes.

    The growing prevalence of obesity and its related metabolic disorders in adolescents shows the necessity of urgent focus on the related factors. Adipocytes secretions and their pro- or anti-inflammatory roles play effective roles in adipocytes metabolism. We assessed the relation between adiponectin, chemerin and lipid profile in hit phase of life. This case-control study conducted on 78 adolescent girls, divided based on BMI percentile. Serum chemerin, adiponectin, lipid profile and body fat mass were measured. Data were analyzed using Pearson correlation test. The interactive relation between these variables was assessed using Structural Equation Modeling (SEM). Data were analyzed using SPSS software and AMOS software. Chemerin were correlated significantly with triglyceride (r=0.584 versus r=0.319), HDL-cholestrol (r=-0.323 versus r=-0.335), LDL-cholestrol (r=0.368 versus r=0.327) and fat mass (r=0.372 versus r=0.357) in obese versus non-obese girls; while the mentioned correlation were non-significant with total cholesterol in obese group (r=0.233 versus r=0.336). Furthermore, there were significant association between adiponectin and triglyceride (r=-0.404 versus r=-0.317), HDL-cholesterol (r=0.332 versus r=0.316) and fat mass (r=-0.529 versus r=-0.346) in obese versus non-obese girls, respectively. There were positive associations between lipid profile components and serum chemerin levels. Adiponectin levels were in positive correlation with HDL-cholesterol concentrations. Chemerin showed positive correlations with potent health threatening components of lipid profile including triglyceride and cholesterol levels in adolescents. Copyright © 2016 Diabetes India.

    Full Text Available Background: Non-obese individuals could have metabolic disorders that are typically associated with elevated body mass index (BMI, placing them at elevated risk for chronic diseases. This study aimed to describe the prevalence and distribution of metabolically obese, non-obese (MONO individuals in Malaysia. Methods: We conducted a cross-sectional study involving teachers recruited via multi-stage sampling from the state of Melaka, Malaysia. MONO was defined as individuals with BMI 18.5–29.9 kg/m2 and metabolic syndrome. Metabolic syndrome was diagnosed based on the Harmonization criteria. Participants completed self-reported questionnaires that assessed alcohol intake, sleep duration, smoking, physical activity, and fruit and vegetable consumption. Results: A total of 1168 teachers were included in the analysis. The prevalence of MONO was 17.7% (95% confidence interval [CI], 15.3–20.4. Prevalence of metabolic syndrome among the normal weight and overweight participants was 8.3% (95% CI, 5.8–11.8 and 29.9% (95% CI, 26.3–33.7, respectively. MONO prevalence was higher among males, Indians, and older participants and inversely associated with sleep duration. Metabolic syndrome was also more prevalent among those with central obesity, regardless of whether they were normal or overweight. The odds of metabolic syndrome increased exponentially from 1.9 (for those with BMI 23.0–24.9 kg/m2 to 11.5 (for those with BMI 27.5–29.9 kg/m2 compared to those with BMI 18.5–22.9 kg/m2 after adjustment for confounders. Conclusions: The prevalence of MONO was high, and participants with BMI ≥23.0 kg/m2 had significantly higher odds of metabolic syndrome. Healthcare professionals and physicians should start to screen nonobese individuals for metabolic risk factors to facilitate early targeted intervention.

    Women undergoing surgery for primary breast cancer can choose between breast conserving therapy and mastectomy (with or without breast reconstruction). Patients often turn to outcomes data to help guide the decision-making process. The BREAST-Q is a validated breast surgery-specific patient-reported outcome measure that evaluates satisfaction, quality of life, and patient experience. It was originally developed for paper-and-pencil administration. However, the BREAST-Q has increasingly been administered electronically. Therefore, the aim of this study was to evaluate the psychometric properties of an electronic version of the BREAST-Q in a large online survey. Women with a history of breast cancer surgery recruited from the Love/AVON Army of Women program completed an electronic version of the BREAST-Q in addition to the Impact of Cancer Survey and PTSD Checklist. Traditional psychometric analyses were performed on the collected data. BREAST-Q data were collected from 6748 women (3497 Breast Conserving Therapy module, 1295 Mastectomy module, 1956 Breast Reconstruction module). Acceptability was supported by a high response rate (82%), low frequency of missing data (BREAST-Q yields highly reliable, clinically meaningful data for use in clinical outcomes research. The BREAST-Q can be used in the clinical setting, whether administered electronically or using paper-and-pencil, at the choice of the patient and surgeon.

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is becoming a severe public health problem that is affecting a large proportion of the world population. Generally, NAFLD in patients is usually accompanied by obesity, hyperglycemia, insulin resistance (IR and type 2 diabetes (T2D, for which numerous animal models have been generated in order to explore the pathogenesis and therapies of NAFLD. On the contrary, quite a number of NAFLD subjects, especially in Asian regions, are non-obese and non-diabetic; however, few animal models are available for the research of non-obese NAFLD. Here, four approaches (here called approach 1 to 4 corresponding to the variable compositions of diets were used to treat tree shrews (Tupaia belangeri chinensis, which have a closer evolutionary relationship to primates than rodents. Analysis of plasma biochemical parameters, hepatic histology, and the expression of hepatic lipid metabolic genes revealed that all four approaches led to hepatic lipid accumulation, liver injury and hypercholesterolemia, but had no effect on body weight and adipose tissue generation, or glycemia. Hepatic gene expression in tree shrews treated by approach 4 might suggest a different or non-canonical pathway leading to hepatic steatosis. In conclusion, the tree shrew displays hepatic steatosis and dyslipidemia, but remains non-obese and non-diabetic under high energy diets, which suggests that the tree shrew may be useful as a novel animal model for the research of human non-obese NAFLD.

    The association between osteoarthritis (OA) and obesity can lead to a reduced functional capacity, compromising the quality of life (QoL) of the elderly. To compare the functional capacity and QoL of obese and non-obese older adults with knee OA. The sample consisted of 35 subjects with OA divided into two groups, obese and non-obese subjects, according to their body mass index. To assess functional capacity, performance tests such as Timed Up and Go (TUG), gait speed test, and the six-minute walk test (6 MWT) were carried out. To assess QoL, WOMAC and SF-36 questionnaires were administered. We performed descriptive and inferential statistics using SPSS software version 20.0. Elderly patients with OA were divided into two groups (obese, n=16; non-obese, n=19). Socio-demographic characteristics were similar between groups (p>0.05). The obese group showed a worst performance in TUG, brisk walking speed and 6 MWT. A more severe pain was found in the following items: "performing heavy housework chores", "going down stairs", "bending to floor" and "getting up from bed" in the obese group (pstairs", "rising from a chair", "standing" and "getting on/off toilet" (p0.05). OA associated with obesity caused a negative impact on functional capacity; however, quality of life scores were low, and no difference in obese and non-obese subjects was found.

    Full Text Available Introduction: Coronary artery disease (CAD is the leading cause of death and disability all over the world. A sedentary lifestyle and dyslipidemia are known to be the major risk factors, which play an important role in the progression of coronary artery disease. Regarding gender differences, the risk of developing coronary heart disease is recognized as being different between non-obese males and non-obese females. Hence, the aim of this study is to assess the benefits of a comprehensive cardiac rehabilitation program (CRP on the functional capacity and lipid profiles, such as, total cholesterol, triglycerides, low density lipoprotein cholesterol, and high density lipoprotein cholesterol in non-obese males and non-obese females with coronary artery disease, and comparing these groups. Materials and Methods: We evaluated 585 non-obese males and females with coronary artery disease. All the participants completed the cardiac rehabilitation program for two months, which included 24 exercise training sessions, medical evaluation, and consultation. For investigation of the effects of the cardiac rehabilitation program on the functional capacity and lipid profiles, exercise tests were carried out by each patient, and also, their blood samples were taken on entrance and at the end of this period. Results: The findings, following 24 sessions in the cardiac rehabilitation program, showed that the functional capacity (P = 0.00 and all lipid profiles had significantly improved in both the groups, except that the high density lipoprotein cholesterol did not show a significant difference in non-obese females. In addition, comparing the two groups did not show any significant differences in lipid profiles, but the changes in functional capacity were significant (P = 0.00 between the two groups, following the cardiac rehabilitation program. Conclusion: The CRP, which was performed by the patients under supervision of a physician and an exercise physiologist

    This study was designed to compare differences in pulmonary gas exchange at rest and at peak exercise in two groups of women: (1) physically active, non-obese women and (2) women with morbid obesity. Fourteen morbidly obese women (body mass index or BMI=49+/-7 kg/m2; peak oxygen consumption or VO2 peak=14+/-2 ml/(kg min)) and 14 physically active non-obese women (BMI=22+/-2 kg/m2; VO2 peak=50+/-6 ml/(kg min)) performed an incremental, ramped exercise test to exhaustion on a cycle ergometer. Arterial blood was sampled at rest and at peak exercise. At rest, the alveolar to arterial oxygen partial pressure difference was 3x higher in the obese women (14+/-10 mmHg) compared to non-obese women (5+/-4 mmHg). Arterial carbon dioxide pressure (PaCO2) was identical in both groups at rest (37+/-4 mmHg). Only the non-obese women showed a decrease in PaCO2 rest to peak exercise (-5+/-3 mmHg). The slope between heart rate and VO2 during exercise was higher in the morbidly obese compared to non-obese women indicating that for the same absolute increase in VO2 a larger increase in heart rate is needed, demonstrating poorer cardiac efficiency in obese women. In conclusion, morbidly obese women have poorer exercise capacity, cardiac efficiency, and compensatory hyperventilation at peak exercise, and poorer gas exchange at rest compared to physically active, non-obese women.

    This study was a cross-sectional survey conducted among 122 women workers employed in the electronics factories in the Ulu Klang Free Trade Zone (FTZ) and the Bangi FTZ, Selangor, Peninsular Malaysia. The purpose of the study was to examine the problem of overweight (>25.0 kg/m2) among this group of women, and factors (socio-demographic, work, exercise, and dietary) associated with overweight, and, to study the food intake pattern of the women in both the overweight and non-overweight groups. Data was collected using a set of questionnaires, while anthropometric measurements were obtained to calculate body mass index (BMI) and waist hip ratio (WHR). The results of the study indicated that 64.0% of the women were overweight (29.5% pre-obese, 34.5% obese). About one-tenth of the women (11.5%) had a WHR of above 0.85. From the bivariate analysis, it was found that women who were older, ever married, had lower educational level, had higher salary, not living in the hostel, involved in shiftwork, and trying to lose weight were more likely to be overweight. After adjusting for age, each of the above factors, except for educational level, remained significantly associated with overweight. Women's diet was found to be monotonous and lacking in variety as accessibility to and availability of a variety of food was a problem for them due to the nature of their work. They also had a sedentary lifestyle. Therefore, further research focusing on changing the poor dietary habits and sedentary lifestyle of the women workers is necessary to address the problem of overweight.

    A deranged mucosal immune response and dietary factors may play an important role in the pathogenesis of type 1 diabetes. The aims of our work were to look for the presence of small intestinal enteropathy in non-obese diabetic (NOD) mice in relation to the presence of wheat proteins in the diet, and to assess their role in the risk of developing diabetes. Female NOD mice were fed a standard or gluten-free diet or a gluten-free diet with the addition of wheat proteins (MGFD). Small intestine architecture, intraepithelial CD3(+) infiltration, epithelial expression of H2-IA, mRNA for IFN-gamma and IL-4 were assessed. NOD mice fed a standard diet showed reduced villous height, increased intraepithelial infiltration by CD3(+) cells and enhanced expression of H2-IA and IFN-gamma mRNA when compared with mice on the gluten-free diet. The cumulative diabetes incidence at 43 weeks of age was 65% in the latter and 97% in the former (p<0.01). Mice on MGFD also showed increased epithelial infiltration and a higher incidence of diabetes. Mice fed a wheat-containing diet showed a higher incidence of diabetes, signs of small intestinal enteropathy and higher mucosal levels of proinflammatory cytokines.

    Polysaccharide (PLP) isolated from Phellinus linteus inhibits tumor growth and metastasis by enhancing immune functions of macrophages, dendritic cells, NK cells, T cells, and B cells. Here, we report that PLP can inhibit the development of autoimmune diabetes in non-obese diabetic (NOD) mice. Although 80% of the NOD mice had developed diabetes by 24 weeks of age, none of the PLP-treated NOD mice developed diabetes. The mean blood glucose levels were 110mg/dl in PLP-treated mice and 499mg/dl in control NOD mice. Histological examination of the pancreatic islets revealed that most of the islets isolated from PLP-treated mice were less infiltrated with lymphocytes compared with those of control mice. Spleen cells from diabetic NOD mice could adaptively transfer diabetes into NOD/SCID mice, but those from PLP-treated NOD mice showed delayed transfer of diabetes. PLP inhibited the expression of inflammatory cytokines, including IFN-gamma, IL-2, and TNF-alpha by Th1 cells and macrophages, but up-regulated IL-4 expression by Th2 cells in NOD mice. PLP did not prevent streptozotocin-induced diabetic development in ICR mice. Taken together, these results suggest that PLP inhibits the development of autoimmune diabetes by regulating cytokine expression.

    To determine the benefits of a 10-wk resistance training programme on cardiovascular health in non-obese and active adolescents. This is a pragmatic randomised controlled intervention. The study was carried out in a Hong Kong Government secondary school. Thirty-eight lean and active boys and girls were randomised to either the resistance training group or the control group. Students in the resistance training group received in-school 10-wk supervised resistance training twice per week, with each session lasting 70 min. Main outcome measures taken before and after training included brachial endothelial dependent flow-mediated dilation, body composition, fasting serum lipids, fasting glucose and insulin, high sensitive C-reactive protein, 24-h ambulatory blood pressure and aerobic fitness. The only training related change was in endothelial dependent flow-mediated dilation which increased from 8.5% to 9.8%. A main effect of time and an interaction (P training. Main effects for time (P training effect. Ten weeks of resistance training in school appears to have some vascular benefit in active, lean children.

    The non-obese diabetic (NOD) mouse is a polygenic model for type 1 diabetes that is characterized by insulitis, a leukocytic infiltration of the pancreatic islets. During ~35 years since the original inbred strain was developed in Japan, NOD substrains have been established at different laboratories around the world. Although environmental differences among NOD colonies capable of impacting diabetes incidence have been recognized, differences arising from genetic divergence have not been analyzed previously. We use both mouse diversity array and whole-exome capture sequencing platforms to identify genetic differences distinguishing five NOD substrains. We describe 64 single-nucleotide polymorphisms, and two short indels that differ in coding regions of the five NOD substrains. A 100-kb deletion on Chromosome 3 distinguishes NOD/ShiLtJ and NOD/ShiLtDvs from three other substrains, whereas a 111-kb deletion in the Icam2 gene on Chromosome 11 is unique to the NOD/ShiLtDvs genome. The extent of genetic divergence for NOD substrains is compared with similar studies for C57BL6 and BALB/c substrains. As mutations are fixed to homozygosity by continued inbreeding, significant differences in substrain phenotypes are to be expected. These results emphasize the importance of using embryo freezing methods to minimize genetic drift within substrains and of applying appropriate genetic nomenclature to permit substrain recognition when one is used.

    Background: Wound infection risk is inversely related to subcutaneous oxygenation, which is reduced in obese patients and may be reduced even more during laparoscopic procedures. Methods: We evaluated subcutaneous tissue oxygenation (PsqO2) in 20 patients with a body mass index (BMI) ≥40 kg·m–2 (obese) and 15 patients with BMI obese) undergoing laparoscopic surgery with standardised anaesthesia technique and fluid administration. Arterial oxygen tension was maintained near 150 mmHg. PsqO2 was measured from a surrogate wound on the upper arm. Data were analyzed with unpaired two-tailed t or Wilcoxon rank-sum tests; P obese patients to reach an arterial oxygen tension of 150 mmHg; however, an FIO2 of only 40% (7%) was required to reach the same oxygen tension in non-obese patients (P=0.007). PsqO2 was significantly less in obese patients: 41 (10) vs. 57 (15) mmHg (PObesity reduces the amount of inspired oxygen required to obtain a given arterial partial pressure and tissue oxygenation. Both factors probably contribute to high infection risk in obese patients. PMID:15978153

    The non-obese diabetic (NOD) mouse spontaneously develops type 1 diabetes (T1D) and has thus served as a model for understanding the genetic and immunological basis, and treatment, of T1D. Since its initial description in 1980, however, the field has matured and recognized that prevention of diabetes in NOD mice (i.e., preventing the disease from occurring by an intervention prior to frank diabetes) is relatively easy to achieve and does not correlate well with curing the disease (after the onset of frank hyperglycemia). Hundreds of papers have described the prevention of diabetes in NOD mice but only a handful have described its actual reversal. The paradoxical conclusion is that preventing the disease in NOD mice does not necessarily tell us what caused the disease nor how to reverse it. The NOD mouse model is therefore best used now, with respect to human disease, as a way to understand the genetic and immunologic causes of and as a model for trying to reverse disease once hyperglycemia occurs. We describe how genetic approaches to identifying causative gene variants can be adapted to identify novel therapeutic agents for reversing new-onset T1D.

    Among the active components in traditional anti-diabetic herbal plants, berberine which is an isoquinoline alkaloid exhibits promising potential for its potent anti-inflammatory and hypoglycemic effects. However, the berberine effect on serum glucose levels in type 1 diabetes (T1D) subjects still remains unknown. This study investigated berberine's effects on serum glucose levels using non-obese diabetic (NOD) mice that spontaneously develop T1D. The NOD mice were randomly divided into four groups, administered water with 50, 150, and 500 mg berberine/kg bw, respectively, through 14 weeks. ICR mice were also selected as a species control group to compare with the NOD mice. Changes in body weight, oral glucose challenge, and serum glucose levels were determined to identify the protective effect of berberine on T1D. After the 14-week oral supplementation, berberine decreased fasting serum glucose levels in NOD mice close to the levels in normal ICR mice in a dose dependent manner. Serum berberine levels showed a significantly (Pberberine-administered NOD mice. Our results suggested that berberine supplemented at appropriate doses for 14 weeks did not cause toxic side effects, but improved hyperglycemia in NOD mice.

    Islet autoimmunity in children who later progress to type 1 diabetes is preceded by dysregulated serum metabolite profiles, but the origin of these metabolic changes is unknown. The gut microbiota affects host metabolism and changes in its composition contribute to several immune-mediated diseases; however, it is not known whether the gut microbiota is involved in the early metabolic disturbances in progression to type 1 diabetes. We rederived non-obese diabetic (NOD) mice as germ free to explore the potential role of the gut microbiota in the development of diabetic autoimmunity and to directly investigate whether the metabolic profiles associated with the development of type 1 diabetes can be modulated by the gut microbiota. The absence of a gut microbiota in NOD mice did not affect the overall diabetes incidence but resulted in increased insulitis and levels of interferon gamma and interleukin 12; these changes were counterbalanced by improved peripheral glucose metabolism. Furthermore, we observed a markedly increased variation in blood glucose levels in the absence of a microbiota in NOD mice that did not progress to diabetes. Additionally, germ-free NOD mice had a metabolite profile similar to that of pre-diabetic children. Our data suggest that germ-free NOD mice have reduced glycaemic control and dysregulated immunologic and metabolic responses.

    Full Text Available Objective: Chronic obstructive pulmonary disease (COPD affects body composition, adipokine secretion, and skeletal integrity. The aim was to determine the association between leptin, body mass (BM and body composition parameters - fat mass (FM and fat mass index (FMI, lean tissue mass (LTM, lean tissue mass index (LTMI and bone mineral density (BMD in 67 male COPD patients. Methods: BM, body composition and biochemical indicators were measured or calculated using standard methods. Data were analyzed according to groups: non-obese (N = 48, BMI 21.0-29.9 kg/m2 and obese (N = 19, BMI ≥ 30.0 kg/m2. Results: In the non-obese group statistically significant correlations were observed: negative ones of age with most BMD T scores, positive ones of BMI with all T scores, FM, FMI, LTMI and leptin, of FMI with leptin and all T scores, and of LTMI with most T scores. In the obese group also statistically significant correlations were found: positive ones of BMI with FMI, LTM, leptin and T scores (trochanter, total hip; of FMI with leptin; and of leptin with total hip T score. Conclusion: A positive relationship between FMI and BMD was found only in non-obese but not in obese COPD patients. Leptin concentration was associated positively with the total hip T score only in obese COPD patients, suggesting its protective role on the skeleton of obese COPD patients.

    Full Text Available Introduction: The abdomen, thighs and buttocks are often the areas of greatest concern to patients following massive weight loss due to bariatric surgery. The typical appearance of the patient who has lost a massive amount of weight derives from a combination of factors, including gender-dependent body morphology and a change in body mass index, which lead to skin and soft-tissue excess and poor skin tone. Thigh laxity and redundancy represents a great challenge to both patients and surgeons. Not only because of the difficulty to satisfy the patients, but also due to the higher incidence of complications especially, with those obese patients who have not undergone bariatric surgery before. The problems with such patients are due to the heavy thighs that require both debulking and tight anchorage to prevent scar migration or labial distortion. Aim of the Work: The aim of the present study is to improve the aesthetic outcome and avoid the complications of medial thigh lifting with simultaneous liposuction in obese and non-obese. Patients and Methods: A total of 25 female patients presented during the period from January 2007 to July 2011 complaining of moderate to severe thigh laxity with or without lipodystrophy. In 20 patients medial transverse thigh lift was performed, to treat medial thigh friction and laxity particularly in the upper half. Whereas, in the other five patients were suffering from upper and lower medial thigh bulkiness, vertical thigh lift was performed. Results: All patients recovered well in 2 weeks and showed improvement of thigh contour. Scar downward displacement in one patient. No skin necrosis or seroma. No labial distortion or separation encountered. Conclusion: Simultaneous liposuction and thigh lift gave good results provided proper patients selection, appropriate technique to each patient, meticulous, cautious liposuction and handling of the tissues and most importantly is the deep tight anchorage sutures to guard

    Intramedullary nailing (IMN) of obese patients with femoral fractures can be difficult due to soft tissue considerations and overall body habitus. Complications including malrotation can occur and have significant impact on postoperative function. The purpose of this study was to evaluate femoral rotation after intramedullary nailing of obese and non-obese patients to see if there was a difference in rotation, complications and any risk factors for malrotation. Between 2000 and 2009, 417 consecutive patients with femur fractures treated with IM nail at Level I trauma and tertiary referral center. Of these, 335 with postoperative computed tomography (CT) scanogram of the bilateral lower extremities were included in this study. Baseline demographic, perioperative and postoperative femoral version calculations were included in the dataset. Statistical analysis included chi-squared test for categorical data, t-test for continuous data, and univariate and multivariate regression analysis. Significance was set at p30. When BMI was categorised into 3 groups (obese patients (BMI 30+), BMI of 35+ was not a significant predictor of version when compared to BMI 30-34.9. There were no significant differences in femoral version based on entry point (antegrade vs. retrograde) in any BMI category. There were also no significant difference between groups of patients with a DFV of >15̊ (p=0.212). Based on this study, BMI did not have an effect on postoperative difference in femoral version. In fact, in our multivariate regression analysis, BMI of over 30 was actually predictive of significantly lower difference in femoral version. While other studies have documented the intraoperative difficulties encountered with obese patients with femur fractures, the outcome of femoral rotation is not affected by an increasing BMI.

    Diabetes Mellitus is a condition that predisposes a higher risk for the development of osteoporosis. The objective of this study was to investigate the influence of boron supplementation on bone microstructure and strength in control and non-obese diabetic mice for 30days. The animals were supplemented with 40μg/0,5ml of boron solution and controls received 0,5ml of distilled water daily. We evaluated the biochemical parameters: total calcium, phosphorus, magnesium and boron; bone analysis: bone computed microtomography, and biomechanical assay with a three point test on the femur. This study consisted of 28 animals divided into four groups: Group water control - Ctrl (n=10), Group boron control - Ctrl±B (n=8), Group diabetic water - Diab (n=5) and Group diabetic boron - Diab±B (n=5). The results showed that cortical bone volume and the trabecular bone volume fraction were higher for Diab±B and Ctrl±B compared to the Diab and Ctrl groups (p≤0,05). The trabecular specific bone surface was greater for the Diab±B group, and the trabecular thickness and structure model index had the worst values for the Diab group. The boron serum concentrations were higher for the Diab±B group compared to non-supplemented groups. The magnesium concentration was lower for Diab and Diab±B compared with controls. The biomechanical test on the femur revealed maintenance of parameters of the bone strength in animals Diab±B compared to the Diab group and controls. The results suggest that boron supplementation improves parameters related to bone strength and microstructure of cortical and trabecular bone in diabetic animals and the controls that were supplemented.

    Adipokines are biologically active, low-molecular weight peptides, which play a major role in metabolic homeostasis in humans. Leptin has gained increasing attention in pediatrics as a biomarker for various metabolic pathologies. Yet, its usefulness is hampered by the relative lack of reference values from pediatric settings. Accordingly, this study aims to evaluate serum concentrations of leptin, soluble leptin receptor (sOB-R), and free leptin index (FLI) in healthy Danish schoolchildren aged 6-18 years and subsequently to establish reference intervals across sex and age groups. A total of 1193 healthy, non-obese Danish schoolchildren (730 girls, 463 boys) aged 6-18 years (median 11.9) were examined by trained medical staff. Serum leptin and sOB-R concentrations in venous fasting blood samples were quantitated by immunoassay. Percentile curves of leptin, sOB-R, and free leptin index were calculated using the General Additive Model for Location Scale and Shape (GAMLSS). Significant age and sex-dependent differences in circulating leptin levels were found. In boys, the median leptin concentration for all ages combined was 3.35 μg/L (95%-interval: 0.71-22.47) and in girls, it was 9.89 ng/L (95%-interval: 2.06-41.49). For SOB-R, no sex-specific difference was found, and the median sOB-R concentration was 8.24 μg/L (IQR: 3.58-23.74; range: leptin concentration and free leptin index with a gradual and significant increase in girls throughout childhood and adolescence and a significantly higher leptin concentration and free leptin index bell-shaped peak in early adolescence in boys.

    Type 1 Diabetes (T1D) is an autoimmune disease characterized by the pancreatic infiltration of immune cells resulting in T cell-mediated destruction of the insulin-producing beta cells. The successes of the Non-Obese Diabetic (NOD) mouse model have come in multiple forms including identifying key genetic and environmental risk factors e.g. Idd loci and effects of microorganisms including the gut microbiota, respectively, and how they may contribute to disease susceptibility and pathogenesis. Furthermore, the NOD model also provides insights into the roles of the innate immune cells as well as the B cells in contributing to the T cell-mediated disease. Unlike many autoimmune disease models, the NOD mouse develops spontaneous disease and has many similarities to human T1D. Through exploiting these similarities many targets have been identified for immune-intervention strategies. Although many of these immunotherapies did not have a significant impact on human T1D, they have been shown to be effective in the NOD mouse in early stage disease, which is not equivalent to trials in newly-diagnosed patients with diabetes. However, the continued development of humanized NOD mice would enable further clinical developments, bringing T1D research to a new translational level. Therefore, it is the aim of this review to discuss the importance of the NOD model in identifying the roles of the innate immune system and the interaction with the gut microbiota in modifying diabetes susceptibility. In addition, the role of the B cells will also be discussed with new insights gained through B cell depletion experiments and the impact on translational developments. Finally, this review will also discuss the future of the NOD mouse and the development of humanized NOD mice, providing novel insights into human T1D.

    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.

    Background: Traditional cigarette advertising has existed in the US for over 200 years. Studies suggest that advertising has an impact on the initiation and maintenance of smoking behaviors. In recent years, electronic cigarettes (e-cigarettes) emerged on the market as an alternative to the traditional tobacco cigarette. The purpose of this study was to describe advertisements in popular US magazines marketed to women for cigarettes and e-cigarettes. Methods: This study involved analyzing 99 issues of 14 popular US magazines marketed to women. Results: Compared to advertisements for traditional cigarettes, advertisements for e-cigarettes were more often found in magazines geared toward the 31–40-year-old audience (76.5% vs. 53.1%, P = 0.011) whereas traditional cigarette advertisements were nearly equally distributed among women 31–40 and ≥40 years. More than three-quarters of the e-cigarette advertisements presented in magazines aimed at the higher median income households compared to a balanced distribution by income for traditional cigarettes (P = 0.033). Conclusions: Future studies should focus on specific marketing tactics used to promote e-cigarette use as this product increases in popularity, especially among young women smokers. PMID:27688867

    Electronic cigarettes (e-cigarettes) are a relatively recent phenomenon, serving dual roles as an alternative vehicle for nicotine delivery and a smoking-cessation tool. The purpose of this study was to determine pregnant women's knowledge, attitudes, and practice regarding electronic cigarettes. A voluntary, anonymous survey was distributed to a convenience sample of pregnant women presenting to a university-based outpatient clinic. After survey completion, participants received information about smoking cessation and e-cigarettes. Data were examined using χ² and Fisher exact tests and analysis of variance. Stata was used for the analysis. Of the 326 surveys distributed, 316 were completed (97%). Of the 316 participants, 42 (13%) reported having ever used e-cigarettes. Only 2 (0.6%) reported current daily use. Ever users were slightly older (27.3 years vs 25.4 years; P = 0.007) and more likely to be current smokers (43% vs. 14%; P Knowledge of the harms of smoking was similar between the 2 groups. Overall, 57% of all respondents believed that e-cigarettes contain nicotine, 61% that e-cigarettes can be addictive, and 43% that e-cigarettes are less harmful to a fetus than traditional cigarettes. Among ever users, the most common reasons given for the use of e-cigarettes were the perception of less harm than traditional cigarettes (74%) and help with smoking cessation (72%). Misconceptions about e-cigarettes are common among pregnant women, potentially motivating use that may pose risks to both maternal and child health. Screening and education regarding e-cigarettes should be included in prenatal care. Future research in this area is necessary, including research examining pregnancy outcomes among women who use e-cigarettes.

    The oxidative biomarkers play an important role in the genesis of cardiometabolic risk-related processes. To investigate the total antioxidant capacity of plasma and its association with cardiometabolic risk in non-obese and clinically healthy young adults. University students of the state of Sergipe, Brazil, aged between 18 and 25 years, were recruited for this study from May of 2013 and October of 2014. Anthropometric, clinical and biochemical parameters were measured and analyzed using protocols which were previously standardized and described in the literature. The measurement of plasma total antioxidant capacity was based on the ability that all the antioxidants present in the sample (plasma) have to inhibit the oxidation of the oxidizable substrate ABTS (2,2`- Azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS•+ by metmyoglobin. Approximately 25% of the sample presented more than one component of cardiometabolic risk. Low HDL-cholesterol was the most prevalent component. Compared to absence of components, the subjects with at least one component presented greater body weight and waist circumference, higher levels of diastolic blood pressure and fasting glucose, greater total cholesterol/HDL-c ratio, and lower levels of HDL-c (p literatura.

    Full Text Available Abstract Background In the UK, obesity is associated with a clear socioeconomic gradient, with individuals of lower socioeconomic status being more likely to be obese. Several previous studies, using individual measures of soecioeconomic status, have shown a more rapid increase in Body Mass Index (BMI over time among adults of lower socioeconomic status. We conducted a study to further examine whether ecologically defined deprivation status influences within-individual BMI change during middle life, as the answer to this question can help determine optimal preventive strategies both for obesity per se, and its' associated socioeconomic disparities. Methods Anonymised records of participants to the Stockport population-based cardiovascular disease risk factor screening programme were analysed. Individuals aged 35–55 who had a first screening episode between 1989 and 1993, and a subsequent screening episode were included in the study. Deprivation status was defined using quintiles of the Townsend score. Mean annual BMI change by deprivation group was calculated using linear regression. Subsequently, deprivation group was included in the model as an ordinal variable, to test for trend. The modelling was repeated separately for individuals who were obese (BMI Results Of 21,976 women and 19,158 men initially screened, final analysis included just over half of all individuals [11,158 (50.8% women and 9,831 (51.3% men], due to the combined effect of loss to follow-up and incomplete BMI ascertainment. In both sexes BMI increased by 0.19 kg/m2 annually (95% Confidence Intervals 0.15–0.24 for women and 0.16–0.23 for men. All deprivation groups had similar mean annual change, and there was no evidence of a significant deprivation trend (p = 0.801, women and 0.892, men. Restricting the analysis to individuals who were non-obese at baseline did not alter the results in relation to the lack of a deprivation effect. When restricting the analysis to

    Claudio Andrade

    Full Text Available Abstract Background: Childhood obesity is associated with increased risk of atherosclerosis and cardiovascular disease in adulthood. Increased intima-media thickness (IMT of the carotid artery is linked to the initiation and progression of the chronic inflammatory processes implicated in cardiovascular disease. Matrix metalloproteinase-9 (MMP-9 plays an important role in the degradation of the extracellular matrix and, consequently, in the development, morphogenesis, repair and remodeling of connective tissues. Objectives: (i to determine and compare the concentrations of MMP-9, tissue inhibitor of metalloproteinase -1 (TIMP-1, and MMP-9/TIMP-1 ratio in obese and non-obese children and adolescents; (ii to investigate the association of these markers with common and internal IMT of carotid arteries. Methods: Cross-sectional study involving 32 obese and 32 non-obese (control individuals between 8 - 18 years of age. Results: Significantly (p < 0.05 higher values of MMP-9 concentration, as well as a higher MMP-9/TIMP-1 ratio were detected in the obese group compared to control counterparts. Common and internal carotid IMT values were significantly higher (p < 0.001 in the obese group compared to the control group. Positive correlations were observed between the common carotid IMT values and MMP-9 concentrations as well as MMP-9/TIMP-1 ratio. Conclusions: Our data demonstrate that obese children and adolescents present higher mean IMT values, plasma MMP-9 and MMP-9/TIMP-1 ratio compared to the non-obese. Thus, these findings indicate that this group presents a risk profile for early atherosclerosis.

    Full Text Available Context: Acne vulgaris (AV is a common disease affecting all ages and ethnic groups. Androgens, skin and serum lipids, inflammatory signaling and regulatory neuropeptides seem to be involved in this multi-factorial process. Aim: The aim of this work was to determine hormonal levels and lipid profile in non-obese, non-hirsute females with AV. Subjects and Methods: A total of 60 non-obese, non-hirsute female cases with different grades of AV and 60 age- and gender-matched healthy volunteers were included. Measurement of serum total and free testosterone, sex hormone binding globulin (SHBG, estradiol and progesterone and blood lipids was done during the luteal phase of the menstrual cycle. Results: Total testosterone, free testosterone (FT and progesterone levels were significantly higher (P < 0.001 for all while estradiol levels (P < 0.001 and SHBG (P < 0.01 were significantly lower in cases than controls. Total cholesterol and low density lipoprotein cholesterol (LDL-C levels were significantly higher (P < 0.001 for both while high density lipoprotein cholesterol (HDL-C and apolipoprotein A-1 (ApoA-1 levels were significantly lower (P < 0.001 for both in cases than controls. Higher values of FT (P = 0.03 and SHBG (P = 0.02 and lower values of estradiol (P = 0.04 levels were significantly in favor of severe acne. Higher values of cholesterol (P < 0.001 and LDL-C (P = 0.03 and lower values of HDL-C (P = 0.01 and ApoA-1 (P = 0.02 levels were significantly associated with severe acne. Conclusion: Changes in hormone levels and lipid profile in non-obese and non-hirsute females with AV should be considered in disease pathogenesis and in treatment prescription of these patients.

    To examine relationships between knowledge, attitudinal and behavioral factors, and obesity and to determine how these factors influence obesity status in west Philadelphia female adolescents. A matched-pairs study was conducted with 32 stature- and age-matched pairs of obese (body mass index and triceps skinfold > or =95th percentile of National Health and Nutrition Examination Survey I) and non-obese (body mass index and triceps skinfold between the 15th and 85th percentiles of National Health and Nutrition Examination Survey I) female African American adolescents (aged 11 to 15 years), selected from a school-based study sample, based on obesity status and matching criteria. Adolescents were compared on the following measures: physical activity, inactivity, dietary intake, eating attitudes, health behavior knowledge, body image, self-esteem, and maturation status. Differences between obese and non-obese females were tested using paired t tests and Wilcoxon matched-pairs signed-rank tests. Physical activity, inactivity, and perception of ideal body size emerged as the most important contributory factors to obesity status. There were no statistically significant matched-pair differences in macronutrient and micronutrient intakes, self-esteem, eating attitudes, health behavior knowledge, or maturation status of these adolescents. Obese adolescents had significantly lower levels of physical activity, higher inactivity, and a larger perception of ideal body size than non-obese adolescents. Knowledge and attitudinal factors (with the exception of perception of ideal body size) had far less association with obesity than activity-related behavioral factors. These findings suggest that future intervention strategies should pay particular attention to physical activity, inactivity, and body image attitudes.

    Obesity contributes to Type 2 diabetes by promoting systemic insulin resistance. Obesity causes features of metabolic dysfunction in the adipose tissue that may contribute to later impairments of insulin action in skeletal muscle and liver; these include reduced insulin-stimulated glucose transport, reduced expression of GLUT4, altered expression of adipokines, and adipocyte hypertrophy. Animal studies have shown that expansion of adipose tissue alone is not sufficient to cause systemic insulin resistance in the absence of adipose tissue metabolic dysfunction. To determine if this holds true for humans, we studied the relationship between insulin resistance and markers of adipose tissue dysfunction in non-obese individuals. 32 non-obese first-degree relatives of Type 2 diabetic patients were recruited. Glucose tolerance was determined by an oral glucose tolerance test and insulin sensitivity was measured with the hyperinsulinaemic-euglycaemic clamp. Blood samples were collected and subcutaneous abdominal adipose tissue biopsies obtained for gene/protein expression and adipocyte cell size measurements. Our findings show that also in non-obese individuals low insulin sensitivity is associated with signs of adipose tissue metabolic dysfunction characterized by low expression of GLUT4, altered adipokine profile and enlarged adipocyte cell size. In this group, insulin sensitivity is positively correlated to GLUT4 mRNA (R = 0.49, p = 0.011) and protein (R = 0.51, p = 0.004) expression, as well as with circulating adiponectin levels (R = 0.46, 0 = 0.009). In addition, insulin sensitivity is inversely correlated to circulating RBP4 (R = -0.61, 0 = 0.003) and adipocyte cell size (R = -0.40, p = 0.022). Furthermore, these features are inter-correlated and also associated with other clinical features of the metabolic syndrome in the absence of obesity. No association could be found between the hypertrophy-associated adipocyte

    Poor cardiovascular fitness (CVF) is a risk factor for obesity, as well as insulin resistance (IR), inflammation, and cardiovascular disease. We have previously shown that a school-based fitness curriculum can improve CVF, as well as IR and body composition in obese children. Whether such a program improves CVF, IR, and other health indicators in non-obese children is unresolved. To determine whether a school-based fitness program improves body composition, CVF, markers of inflammation (e.g. CRP, TNF-alpha, adiponectin), and insulin sensitivity in nonobese children. 35 non-obese middle school children with body mass index below the 95th percentile for age were enrolled in a 'fitness-oriented' gym class. Children underwent fasting evaluation of insulin, glucose, adiponectin, CRP, TNF-alpha, body composition by dual X-ray absorptiometry (DXA), and maximal VO2 treadmill testing at baseline (prior to the school year) and again at end of the school year. Testing for CVF (maximal VO2 treadmill testing), DXA, and fasting evaluation of insulin, glucose, adiponectin, CRP and TNF-alpha. Children demonstrated a decrease in BMI z-score (-0.14 +/- 0.33, p = 0.02), HOMA-IR (-0.15 +/- 0.35, p = 0.016), and TNF-alpha (-2.55 +/- 1.79 pg/ml, p VO2(max) (+1.58 +/- 2.34 ml/kg/min, p < 0.001), adiponectin (+7,553 +/- 11,100 ng/ml, p < 0.001), and muscle mass (+2,282 +/- 1,882.73 g, p < 0.001) after nine months of study. The school-based fitness oriented curriculum resulted in improved body composition and insulin sensitivity, increased CVF, and decreased inflammation in non-obese children. Combined with prior studies, these data demonstrate that school-based fitness curricula can benefit both obese and non-obese children. Partnerships with schools to promote fitness should be part of a public health approach to improving children's health.

    Full Text Available Normal 0 false false false EN-US JA X-NONE This article reflects upon the research methods employed for microfemininewarfare (2012, an interactive database documentary that investigates female electronic dance music (EDM artists. The purpose of the documentary is to feature the contributions of women as composers, to show how they came to be composers and to reveal the tactics used to approach significant issues of gender in the male-dominated world of EDM. I highlight the theoretical and methodological processes that went into the making of this documentary, subtitled “exploring women’s space in electronic music”. By constructing “electronic music by women” as a category, two objectives are addressed: first, the visibility of women’s contribution to the musical tradition is heightened; and, second, it allows an exploration of the broadening of discourses about female subjectivity. This article showcases feminist research-creation and friendship-as-method as effective research methods to glean meaningful content when applied to EDM fieldwork.

    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.

    Prevention of weight gain in adults is a major public health target. Animal experiments have consistently demonstrated a relationship between fermentable carbohydrate intake, such as oligofructose, anorectic gut hormones, and appetite suppression and body weight control. This study was designed to determine the dose of oligofructose which would augment the release of anorectic gut hormones and reduce appetite consistently in non-obese humans. Twelve non-obese participants were recruited for a 5-week dose-escalation study. Following a 9-14-day run-in, participants increased their daily oligofructose intake every week from 15, 25, 35, 45, to 55 g daily. Subjective appetite and side effects were monitored daily. Three-day food diaries were completed every week. Appetite study sessions explored the acute effects of 0, 15, 35, and 55 g oligofructose on appetite-related hormones, glycaemia, subjective appetite, and energy intake. In the home environment, oligofructose suppressed hunger, but did not affect energy intake. Oligofructose dose-dependently increased peptide YY, decreased pancreatic polypeptide and tended to decrease ghrelin, but did not significantly affect appetite profile, energy intake, glucose, insulin, or glucagon-like peptide 1 concentrations during appetite study sessions. In conclusion, oligofructose supplementation at ≥ 35 g/day increased peptide YY and suppressed pancreatic polypeptide and hunger; however, energy intake did not change significantly.

    Skeletal muscle resistance to insulin is related to accumulation of lipid-derived products, but it is not clear whether this accumulation is caused by skeletal muscle mitochondrial dysfunction. Diabetes and obesity are reported to have a selective effect on the function of subsarcolemmal and interfibrillar mitochondria in insulin-resistant skeletal muscle. The current study investigated the role of the subpopulations of mitochondria in the pathogenesis of insulin resistance in the absence of obesity. A non-obese spontaneous rat model of type 2 diabetes mellitus, (Goto-Kakizaki), was used to evaluate function and biochemical properties in both populations of skeletal muscle mitochondria. In subsarcolemmal mitochondria, minor defects are observed whereas in interfibrillar mitochondria function is preserved. Subsarcolemmal mitochondria defects characterized by a mild decline of oxidative phosphorylation efficiency are related to ATP synthase and structural alterations of inner mitochondria membrane but are considered unimportant because of the absence of defects upstream as shown with polarographic and spectrophometric assays. Fatty acid transport and oxidation is preserved in both population of mitochondria, whereas palmitoyl-CoA increased 25% in interfibrillar mitochondria of diabetic rats. Contrary to popular belief, these data provide compelling evidence that mitochondrial function is unaffected in insulin-resistant skeletal muscle from T2DM non-obese rats.

    STUDY OBJECTIVE, DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Bleeding disorders (BD) occur in up to 50% of adolescents with heavy menstrual bleeding (HMB). This presents unique challenges to health care providers because of the complexity of treating the condition and such complexity can result in difficulty with patients understanding basic information about their condition, limit communication with medical providers, and patient compliance. The aim of the study was to use an electronic approach to enhance patient compliance with medications used to treat their HMB, and to provide educational access to adolescents with BD. This was a prospective cohort study involving patients in a Young Women's Bleeding Disorder Clinic at a single children's hospital. Subjects were given an iPod Touch (Apple Inc, Cupertino, CA) device (ITD), preloaded with the iPeriod (Winkpass Creations) application. Participants recorded information about their BD that they learned about on BD Web sites, and menses, and medications. Electronic and charted data were collected to monitor compliance with prescribed treatment regimens. All ITD allowed Wi-Fi access to allow teens to explore BD Web sites and knowledge was assessed.

    The dopaminergic system is involved in the regulation of food intake, which is crucial for the maintenance of body weight. We examined the relationship between striatal dopamine (DA) D2/3 receptor availability and body mass index (BMI) in 25 non-obese healthy male subjects using [(11)C]raclopride and positron emission tomography. None of [(11)C]raclopride binding potential (BP) values (measures of DA D2/3 receptor availability) in striatal subregions (dorsal caudate, dorsal putamen, and ventral striatum) in the left and right hemispheres was significantly correlated with BMI. However, there was a positive correlation between the right-left asymmetry index of [(11)C]raclopride BP in the dorsal putamen and BMI (r=0.43, pputamen relative to the left in non-obese individuals. The present results, combined with previous findings, may also suggest neurochemical mechanisms underlying the regulation of food intake in non-obese individuals.

    It is well-known that plasma L-carnitine concentrations are significantly decreased in obese individuals. A study showed that L-carnitine concentrations are significantly lower in lean PCOS patients than in lean healthy women. Thus, it has been suggested that lowered L-carnitine is associated with PCOS. This study also showed that the women with PCOS had significantly lower L-carnitine levels than those of the healthy controls. In addition, this study hypothesised that low L-carnitine levels in PCOS patients were associated with obesity and/or insulin resistance. Moreover, plasma L-carnitine concentrations were found to be statistically similar in PCOS patients and healthy controls, when controlled for obesity. This study implied that L-carnitine could be used as an adjunctive therapy in the management of insulin resistance or obesity in women who have PCOS. Further research might be planned to clarify the clinical effects of L-carnitine administration in PCOS patients with insulin resistance and/or obesity.

    To determine if asthma control was more difficult to achieve in obese versus non-obese asthmatic children, retrospective analysis was performed on obese and non-obese Los Angeles inner-city children (2 to 18 years of age) with persistent asthma. No difference in time required to achieve control of asthma, ability to maintain control of asthma, baseline pulmonary functions, and number of controllers prescribed was found between the two groups. We conclude that in a Los Angeles inner-city pediatric population, obesity is not a factor in the ability to control asthma.

    Full Text Available Mast cells have been suggested to play key roles in adipogenesis. We herein show that the expression of preadipocyte, but not adipocyte, marker genes increases in the white adipose tissue of mast cell-deficient (KitW-sh/W-sh mice under both obese and non-obese conditions. In vitro culturing with adipogenic factors revealed increased adipocytes differentiated from the KitW-sh/W-sh stromal vascular fraction, suggesting the accumulation of preadipocytes. Moreover, the increased expression of preadipocyte genes was restored by mast cell reconstitution in the KitW-sh/W-sh mice. These results suggest positive effects of mast cells on the preadipocyte to adipocyte transition under both physiological and pathological conditions.

    We describe the preliminary findings of seatbelt compliance among severely injured blunt trauma patients involved in motor vehicle crashes in Mississippi. Stratification of the sample size of 1,405 patients included obese versus the non-obese patients with sub-stratification of weight classes to include normal weight, overweight, obese and morbidly obese. An overview of the design of the study is included. The results demonstrate no significant difference between the numbers of restrained and unrestrained obese patients compared to their normal weight counterparts. Our findings suggest unrestrained patients regardless of weight class had higher ISS than restrained individuals. The data for Mississippi is similar to those reported nationally. Interestingly, we observed the injury severity scores in the restrained obese and morbidly obese patients were higher than the unrestrained motorists within the same weight cohort. This may reflect less movement within the vehicle resulting in less trauma.

    Studies have shown oral insulin prevents type 1 diabetes (T1D) in mouse models, however human trials were inconclusive. We tested the ability of different insulins to prevent T1D in non-obese diabetic mice. Mice received oral insulin or PBS twice weekly and disease was monitored. Contrary to previous studies, no insulin tested showed significant ability to prevent T1D, nor did testing of linked suppression in a delayed type hypersensitivity model have reproducible effect. To investigate delivery of antigen within the GI tract, blue dye was fed to mice. Dye traveled 5-8 cm from stomach to small intestine within 10s, suggesting orally administered antigen may not get digested in the stomach in mice. Insulin incubated with jejunum extracts was instantly digested. Thus, in humans large doses of insulin may be required to achieve tolerance as antigen may be more vulnerable to digestion in the stomach even before reaching the small intestine.

    Full Text Available Abstract Background The use of chromium supplements is widespread for the prevention and treatment of diabetes mellitus but there are conflicting reports on efficacy, possibly reflecting discrepant effects across different populations. In the present studies, we test the hypothesis that chromium supplementation raises serum chromium levels and correspondingly improves insulin sensitivity. Methods A double blind placebo-controlled randomized trial was conducted on 31 non-obese, normoglycemic subjects. After baseline studies, the subjects were randomized to placebo or chromium picolinate 500 μg twice a day. The primary endpoint was change in insulin sensitivity as measured by euglycemic hyperinsulinemic clamp. Pre-specified secondary endpoints included fasting lipids, blood pressure, weight, body composition measured by DXA scan. Results After 16 weeks of chromium picolinate therapy there was no significant change in insulin sensitivity between groups (p=0.83. There was, however, a strong association between serum chromium and change in insulin resistance (β = -0.83, p=0.01, where subjects with the highest serum chromium had a worsening of insulin sensitivity. This effect could not be explained by changes in physiological parameters such as body weight, truncal fat and serum lipids with chromium therapy. Conclusions Chromium therapy did not improve insulin sensitivity in non-obese normoglycemic individuals. Further, subjects who have high serum chromium levels paradoxically had a decline in insulin sensitivity. Caution therefore should be exercised in recommending the use of this supplement. Trial registration The study was registered on the NIH registry (clinicaltrials.gov and the identifier is NCT00846248

    Full Text Available Background: Low serum 25-hydroxy vitamin D (25(OHD has been shown to correlate with an increased risk of type 2 diabetes mellitus (T2DM. The objective of this study was to investigate the association between serum 25(OHD and glycemic and inflammatory markers in non-obese patients with T2DM. Methods: Eighty-four non-obese patients with T2DM were recruited in this cross-sectional study. Demographic, anthropometric, and dietary information was obtained from all the participants. The serum concentrations of glucose, HbA1C, insulin, 25(OHD, and inflammatory markers including tumor necrosis factor-alpha (TNF-α and high sensitive C-reactive protein (hs-CRP were measured. A homeostatic model of insulin resistance (HOMA-IR was also evaluated. Results: The mean serum concentration of 25(OHD was 11.01±5.55 ng/mL. Severe deficiency, deficiency, and insufficiency of vitamin D were detected in 60.71%, 35.72%, and 3.57% of the participants, respectively. The results showed that those in the lowest group of serum 25(OHD had significantly higher TNF-α than did those in the highest group (P=0.026. Although the association between serum 25(OHD and fasting blood sugar and TNF-α was statistically significant (P=0.049 and P=0.044, respectively, the other glycemic markers and hs-CRP did not have any significant relationships with 25(OHD. Conclusion: According to the high prevalence of vitamin D deficiency in the diabetic patients and the inverse relationship between serum 25(OHD and fasting blood sugar and TNF-α in this study, vitamin D status may be a determining factor of systemic inflammation in patients with T2DM. Further studies with larger sample sizes are suggested in this regard.

  7. Positive effects of voluntary running on metabolic syndrome-related disorders in non-obese hereditary hypertriacylglycerolemic rats.

    Full Text Available While metabolic syndrome is often associated with obesity, 25% of humans suffering from it are not obese and the effect of physical activity remains unclear in such cases. Therefore, we used hereditary hypertriaclyglycerolemic (HHTg rats as a unique model for studying the effect of spontaneous physical activity [voluntary running (VR] on metabolic syndrome-related disorders, such as dyslipidemia, in non-obese subjects. Adult HHTg males were fed standard (CD or high-sucrose (HSD diets ad libitum for four weeks. Within both dietary groups, some of the rats had free access to a running wheel (CD+VR, HSD+VR, whereas the controls (CD, HSD had no possibility of extra physical activity. At the end of the four weeks, we measured the effects of VR on various metabolic syndrome-associated parameters: (i biochemical parameters, (ii the content and composition of triacylglycerols (TAG, diacylglycerols (DAG, ceramides and membrane phospholipids, and (iii substrate utilization in brown adipose tissue. In both dietary groups, VR led to various positive effects: reduced epididymal and perirenal fat depots; increased epididymal adipose tissue lipolysis; decreased amounts of serum TAG, non-esterified fatty acids and insulin; a higher insulin sensitivity index. While tissue ceramide content was not affected, decreased TAG accumulation resulted in reduced and modified liver, heart and skeletal muscle DAG. VR also had a beneficial effect on muscle membrane phospholipid composition. In addition, compared with the CD group, the CD+VR rats exhibited increased fatty acid oxidation and protein content in brown adipose tissue. Our results confirm that physical activity in a non-obese model of severe dyslipidemia has many beneficial effects and can even counteract the negative effects of sucrose consumption. Furthermore, they suggest that the mechanism by which these effects are modulated involves a combination of several positive changes in lipid metabolism.

    To evaluate the association between percent body fat (%BF) and body mass index (BMI) among BMI-defined non-obese individuals between 40 and 69 years of age using a population-based Canadian sample. Cross-sectional data from the Canadian Health Measures Survey (2007 and 2009) was used to select all middle-aged individuals with BMI < 30 kg/m2 (n = 2,656). %BF was determined from anthropometric skinfolds and categorized according to sex-specific equations. Association of other anthropometry measures and metabolic markers were evaluated across different %BF categories. Significance of proportions was evaluated using chi-squared and Bonferroni-adjusted Wald test. Diagnostic performance measures of BMI-defined overweight categories compared to those defined by %BF were reported. The majority (69%) of the sample was %BF-defined overweight/obese, while 55% were BMI-defined overweight. BMI category was not concordant with %BF classification for 30% of the population. The greatest discordance between %BF and BMI was observed among %BF-defined overweight/obese women (32%). Sensitivity and specificity of BMI-defined overweight compared to %BF-defined overweight/obese were (58%, 94%) among females and (82%, 59%) among males respectively. According to the estimated negative predictive value, if an individual is categorized as BMI-defined non-obese, he/she has a 52% chance of being in the %BF-defined overweight/obese category. Middle-aged individuals classified as normal by BMI may be overweight/obese based on measures of %BF. These individuals may be at risk for chronic diseases, but would not be identified as such based on their BMI classification. Quantifying %BF in this group could inform targeted strategies for disease prevention.

    Factors related to overweight were examined in a cross-sectional survey that included 1612 women workers from 10 large electronics assembly factories in Peninsular Malaysia. Respondents were Malaysian citizens, direct production workers below the supervisory level, and had worked at least a year in the factory where they were presently employed. Heights and weights were taken to calculate the body mass index (BMI). Weights and BMI increased with increasing age. After adjusting for age, odds ratios for overweight were significantly raised for married women in relation to not married women (OR 1.5, 95% CI=1.15-2.02), lower secondary education in relation to higher than upper secondary education (OR 1.8, 95% CI=1.06-3.14), monthly income RM800-999 (OR 1.7, 95% CI=1.21-2.45) and >/=RM1,000 (OR 1.8, 95% CI=1.23-2.72) in relation to income, and working in rotating shifts. The overall prevalence of overweight was 37.4%; the overall mean BMI was 24.2+/-5.4 kg/m(2). Prevalence of overweight and mean BMI for younger age groups were similar to Malay women in the country-wide representative National Health and Morbidity Survey II, but the older age groups in this study had higher overweight prevalence and mean BMI than the national sample. Electronics women workers face a higher risk of overweight, and is an important group for nutrition intervention.

    Summary Eating behaviors are highly cue-dependent. Changes in mood states and exposure to palatable food both increase craving and consumption of food. Vagal activity supports adaptive modulation of physiological arousal and has an important role in cue-induced appetitive behaviors. Using high-frequency heart rate variability (HF HRV), this preliminary study compared vagal activity during positive and negative mood induction, and presentation of preferred high-calorie food items between obese (n = 12; BMI ≥ 30) and non-obese individuals (n = 14; 18.5 < BMI < 30). Participants completed two laboratory sessions (negative vs. positive mood conditions). Following 3-hours of food deprivation, all participants completed a mood induction, and then were exposed to their preferred high-calorie food items. HF HRV was assessed throughout. Obese and non-obese individuals were not significantly different in HF HRV during positive or negative mood induction. Obese individuals showed significantly greater levels of HF HRV during presentation of their preferred high-calorie food items than non-obese individuals, particularly in the positive mood condition. This is the first study to demonstrate increased vagal activity in response to food cues in obese individuals compared with non-obese individuals. Our findings warrant further investigation on the potential role of vagally-mediated cue reactivity in overeating and obesity. PMID:24847667

    Objective To study the effect of letrozole (LE) on ovarian stimulation in obese and non-obese patients with polycystic ovarian syndrome (PCOS). Methods Forty infertile women with PCOS were selected and divided into obese and non-obese groups based on body mass index (BMI). At days 3 -7 of menstruation or progesterone-withdrawal bleeding, oral LE of 2. 5 mg/d was given, and vagina sonography was followed to monitor the development of follicle. When the diameter of the biggest follicle reached 18 mm, 10 000 U of HCG was injected to trigger ovulation. The numbers of follicle reaching the diameter of ≥ 18 mm and the thickness of endometrium on the day of HCG injection were recorded. Ovulation rate and pregnancy rate were added up, respectively. Results The differences of number of follicle and the thickness of endometrium on the day of HCG injection were not significant between obese and non-obese groups (P>0. 05), and that were also not significant between them in terms of rates of single follicle, ovulation and pregnancy (P>0. 05). Conclusion The effect of LE on ovarian stimulation is similar in obese and non-obese patients with PCOS.%目的 探讨来曲唑(LE)对肥胖型和非肥胖型多囊卵巢综合征(PCOS)病人促排卵影响.方法 选择40例PCOS不孕病人,根据体质量指数(BMI)分为肥胖型组和非肥胖型组,两组均于月经或黄体酮撤退性出血第3~7天给予LE 2.5 mg/d口服治疗,随后阴道B超监测卵泡发育情况,当最大卵泡平均直径≥18 mm时,肌注人绒毛膜促性腺激素(HCG) 10 000 U诱导排卵,并记录HCG注射日直径≥18 mm卵泡数和子宫内膜厚度,分别统计排卵率和妊娠率.结果 两组HCG注射日卵泡数和子宫内膜厚度比较差异无显著性(P>0.05),两组单卵泡率、排卵率和妊娠率比较差异无显著性(P>0.05).结论 LE对肥胖型和非肥胖型PCOS病人促排卵效果相似.

    Of the 1057 women allocated to study, 975 had their weight and height measured. Obese women with fractures had significantly lower SF-36 physical component scores when compared with non-obese subjects with fracture, obese subjects without fractures, and non-obese non-fracture subjects. Both obesity and fractures were independently associated with a lower SF-36 physical component score in the regression model. In conclusion, fractures appear to have an adverse effect on quality of life which is more pronounced in obese postmenopausal women.

    FTY720 is an immunomodulator that alters migration and homing of lymphocytes via sphingosine 1-phosphate receptors. This compound has been shown to be effective in suppressing autoimmune diseases in experimental and clinical settings. In the present study, we tested whether FTY720 prevented autoimmune thyroiditis in iodide-treated non-obese diabetic (NOD) mice, a model of Hashimoto's thyroiditis (HT) in humans. Mice were given 0.05% iodide water for 8 weeks, and this treatment effectively induced thyroiditis. Iodide-treated mice were injected intraperitoneally with either saline or FTY720 during the iodide treatment. FTY720 clearly suppressed the development of thyroiditis and reduced serum anti-thyroglobulin antibody levels. The number of circulating lymphocytes and spleen cells including CD4(+) T cells, CD8(+) T cells, and CD4(+)Foxp3(+) T cells was decreased in FTY720-treated mice. Our results indicate that FTY720 has immunomodulatory effects on iodide-induced autoimmune thyroiditis in NOD mice and may be a potential candidate for use in the prevention of HT.

    The aim of this study was to verify if the addition of satiating nutrients and a satiating context effect could influence appetite sensations, spontaneous energy intake and food appreciation under conditions of standardized energy density of a meal. Eighteen non-obese men were submitted to a control, a satiating, and a context effect condition composed of a standardized breakfast and an ad libitum test lunch (macaroni entrée plus chocolate cake). The satiating macaroni contained more proteins, unsaturated fats, fibres and calcium than the control macaroni despite similar energy density, appearance and palatability. In the context effect condition, participants believed they were eating "a highly satiating macaroni", but were served the control macaroni. Appreciation of the macaronis, quantities of macaroni and cake consumed and 4-h satiating potential were measured for each condition. Quantities of macaroni and dessert consumed did not differ between conditions. Satiating potential was greater for the context effect meal compared to the control and/or the satiating meals up to 4h after its consumption. The context effect macaroni obtained higher appreciation rates than the control and the satiating macaronis. The context effect may positively influence the appreciation toward a meal and contribute to increase its satiety potential for many hours.

    Treg cells endowed with enhanced killing activity through decoration with Fas-ligand (FasL) protein (killer Treg) have been effective in delay of hyperglycemia in prediabetic non-obese diabetic (NOD) mice. In this study, we assessed the therapeutic efficacy of these cells, harvested from age-matched euglycemic NOD donors, on the course of disease in new-onset diabetics. One dose of 4 × 10(6) killer Treg cells stabilized blood glucose associated with increased insulin levels in 5 of 9 mice and partially reversed the severity of islet inflammation, whereas naive Treg cells did not modulate the course of disease significantly. Killer Treg cells were shown to operate through induction of cell apoptosis within the pancreatic lymph nodes, resulting in reduced efficiency of adoptive disease transfer to NOD/SCID recipients. A second mechanism of action consisted of increased fractions of CD4(+)CD25(-)FoxP3(+) T cells in the pancreas and all lymphoid organs. Immunomodulation with FasL rather than Treg cells enhanced the expression of CD25 and FoxP3 in the thymus, suggesting a possible contribution of thymic output to prolonged stabilization of the glucose levels. Autologous Treg cells evolve as excellent vehicles for targeted delivery of FasL as an immunomodulatory protein, which delete pathogenic cells at the site of inflammation and induce systemic dominance of suppressor subsets.

    Human and animal studies strongly suggest that dietary gluten could play a causal role in the etiopathogenesis of type 1 diabetes (T1D). However, the mechanisms have not been elucidated. Recent reports indicate that the intestinal microbiome has a major influence on the incidence of T1D. Since diet is known to shape the composition of the intestinal microbiome, we investigated using non-obese diabetic (NOD) mice whether changes in the intestinal microbiome could be attributed to the pro- and ...

    There is evidence that temperamental factors are associated with obesity; however, the biological mechanism of such association remains elusive. We aimed to investigate a possible association between serotonin transmission and regulative temperament in obese and non-obese individuals by using positron emission tomography (PET) imaging of serotonin transporters (SERT) and the Adult Temperament Questionnaire. Twenty-nine obese individuals with body mass index (BMI) ≥ 35 kg/m(2) and 13 non-obese controls (BMI < 30 kg/m(2) ) underwent PET with [(11) C]-labeled DASB (highly selective for SERT) and self-completed the Effortful Control (EC) scale of the Adult Temperament Questionnaire-Short Form (ATQ). With the help of this questionnaire, we aimed to assess the capacity of self-regulation. Overall, for obese and non-obese individuals together, VOI-based (volume of interest) analysis showed significant negative correlations between SERT BPND and ATQ-EC AC (Activation Control) subscale in several brain regions (all r ≤ -0.47). Obese and non-obese individuals separated showed equally strong positive, but non-significant correlations. The analysis did not reveal any significant correlations of SERT availability and ATQ-EC IC (Inhibitory Control) or ATQ-EC AtC (Attentional Control) subscale within and between the two groups. The results indicate that regulative temperament - particularly the capacity to mitigate negatively toned impulses and to resist inappropriate avoidance behavior - might be associated with the prefrontal serotonergic system.

    We aimed to elucidate the impact of fat cell size and inflammatory status of adipose tissue on the development of type 2 diabetes in non-obese individuals. We characterised subcutaneous abdominal adipose tissue by examining stromal cell populations by 13 colour flow cytometry, measuring expression of adipogenesis genes in the progenitor cell fraction and determining lipolysis and adipose secretion of inflammatory proteins in 14 non-obese men with type 2 diabetes and 13 healthy controls matched for age, sex, body weight and total fat mass. Individuals with diabetes had larger fat cells than the healthy controls but stromal cell population frequencies, adipose lipolysis and secretion of inflammatory proteins did not differ between the two groups. However, in the entire cohort fat cell size correlated positively with the ratio of M1/M2 macrophages, TNF-α secretion, lipolysis and insulin resistance. Expression of genes encoding regulators of adipogenesis and adipose morphology (BMP4, CEBPα [also known as CEBPA], PPARγ [also known as PPARG] and EBF1) correlated negatively with fat cell size. We show that a major phenotype of white adipose tissue in non-obese individuals with type 2 diabetes is adipocyte hypertrophy, which may be mediated by an impaired adipogenic capacity in progenitor cells. Consequently, this could have an impact on adipose tissue inflammation, release of fatty acids, ectopic fat deposition and insulin sensitivity.

    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.

    The derivation of pluripotent embryonic stem cells (ESCs) from a variety of genetic backgrounds remains a desirable objective in the generation of mice functionally deficient in genes of interest and the modeling of human disease. Nevertheless, disparity in the ease with which different strains of mice yield ESC lines has long been acknowledged. Indeed, the generation of bona fide ESCs from the non obese diabetic (NOD) mouse, a well-characterized model of human type I diabetes, has historically proved especially difficult to achieve. Here, we report the development of protocols for the derivation of novel ESC lines from C57Bl/6 mice based on the combined use of high concentrations of leukemia inhibitory factor and serum-replacement, which is equally applicable to fresh and cryo-preserved embryos. Further, we demonstrate the success of this approach using Balb/K and CBA/Ca mice, widely considered to be refractory strains. CBA/Ca ESCs contributed to the somatic germ layers of chimeras and displayed a very high competence at germline transmission. Importantly, we were able to use the same protocol for the derivation of ESC lines from nonpermissive NOD mice. These ESCs displayed a normal karyotype that was robustly stable during long-term culture, were capable of forming teratomas in vivo and germline competent chimeras after injection into recipient blastocysts. Further, these novel ESC lines efficiently formed embryoid bodies in vitro and could be directed in their differentiation along the dendritic cell lineage, thus illustrating their potential application to the generation of cell types of relevance to the pathogenesis of type I diabetes.

    Type 1 diabetes mellitus (T1DM) is an auto-immune disease while oral administrating its autoantigens could be a treatment of T1DM. To express human insulin gene (ins) in lactic acid bacteria (LAB) for oral vaccine, ins gene was replaced by LAB bias codon and an 8-amino-acid-residue linker peptide forming a beta-turn was designed to link insulin chain A and B. After synthesized by primer annealing method, the whole ins gene was fused with signal peptide sequence SP(Usp45), subcloned into a LAB secretory expressive vector pSW501 and then introduced to Lactococcus lactis (L. lactis) MG1363 and Lactobacillus casei (Lb. casei ) ATCC27092 respectively. Western blot showed that the expression product (SP(Usp45)-INS protein) targeted mainly at the cell wall while little was found in cytoplasm or supernatant. The highest expression level emerged in exponential phase when the optical density at 600nm of the culture was 0.4. The culture of the recombinant strain Lb. casei/pSW501 was administered to non-obese diabetic (NOD) mice orally. ELISA and Western blot results showed that the recombinant strain could induce SP(Usp45)-INS-specific antibodies and raise IL-4 level (38.583 +/- 2.083 pg/mL, P < 0.05) in the mice' s sera. Expression of insulin in the food-grade vehicle LAB could induce oral immune tolerance in NOD mice and protect it from pancreas injury, suggesting it might be a new way to the treatment of T1DM.

    The aim of this study was to estimate the effect of carnitine supplementation on lipid disorders and peripheral tissue insulin sensitivity in a non-obese animal model of insulin resistance, the hereditary hypertriglyceridemic (HHTg) rat. Male HHTg rats were fed a standard diet, and half of them received daily doses of carnitine (500 mg·kg(-1) body weight) for 8 weeks. Rats of the original Wistar strain were used for comparison. HHTg rats exhibited increased urinary excretion of free carnitine and reduced carnitine content in the liver and blood. Carnitine supplementation compensated for this shortage and promoted urinary excretion of acetylcarnitine without any signs of (acyl)carnitine accumulation in skeletal muscle. Compared with their untreated littermates, carnitine-treated HHTg rats exhibited lower weight gain, reduced liver steatosis, lower fasting triglyceridemia, and greater reduction of serum free fatty acid content after glucose load. Carnitine treatment was associated with increased mitochondrial biogenesis and oxidative capacity for fatty acids, amelioration of oxidative stress, and restored substrate switching in the liver. In skeletal muscle (diaphragm), carnitine supplementation was associated with significantly higher palmitate oxidation and a more favorable complete to incomplete oxidation products ratio. Carnitine supplementation further enhanced insulin sensitivity ex vivo. No effects on whole-body glucose tolerance were observed. Our data suggest that some metabolic syndrome-related disorders, particularly fatty acid oxidation, steatosis, and oxidative stress in the liver, could be attenuated by carnitine supplementation. The effect of carnitine could be explained, at least partly, by enhanced substrate oxidation and increased fatty acid transport from tissues in the form of short-chain acylcarnitines.

    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)F2 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.

    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.

    Full Text Available Crosslinking ligand-engaged cytotoxic T lymphocyte antigen-4 (CTLA-4 to the T cell receptor (TCR with a bispecific fusion protein (BsB comprised of a mutant mouse CD80 and lymphocyte activation antigen-3 (LAG-3 has been shown to attenuate TCR signaling and to direct T-cell differentiation toward Foxp3(+ regulatory T cells (Tregs in an allogenic mixed lymphocyte reaction (MLR. 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.

    The effects of environmental temperature on blood pressure and hormones in obese subjects in Japan were compared in two seasons: summer vs winter. Five obese (BMI, 32 ± 5 kg/m2) and five non-obese (BMI, 23 ±3 kg/m2) men participated in this experiment at latitude 35°10' N and longitude 136°57.9' E. The average environmental temperature was 29 ± 1 °C in summer and 3 ± 1 °C in winter. Blood samples were analyzed for leptin, ghrelin, catecholamines, thyroid stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), total cholesterol, triglycerides, insulin and glucose. Blood pressure was measured over the course of 24 h in summer and winter. A Japanese version of the Profile of Mood States (POMS) questionnaire was also administered each season. Systolic and diastolic blood pressures in obese men were significantly higher in winter (lower environmental temperatures) than in summer (higher environmental temperatures). Noradrenaline and dopamine concentrations were also significantly higher at lower environmental temperatures in obese subjects, but ghrelin, TSH, fT3, fT4, insulin and glucose were not significantly different in summer and winter between obese and non-obese subjects. Leptin, total cholesterol and triglyceride concentrations were significantly higher in winter in obese than non-obese men. Results from the POMS questionnaire showed a significant rise in Confusion at lower environmental temperatures (winter) in obese subjects. In this pilot study, increased blood pressure may have been due to increased secretion of noradrenaline in obese men in winter, and the results suggest that blood pressure control in obese men is particularly important in winter.

    The role of the central serotonin (5-hydroxytryptamine, 5-HT) system in feeding has been extensively studied in animals with the 5-HT family of transporters (5-HTT) being identified as key molecules in the regulation of satiety and body weight. Aberrant 5-HT transmission has been implicated in the pathogenesis of human obesity by in vivo positron emission tomography (PET) and single-photon emission computed tomography (SPECT) imaging techniques. However, results obtained thus far from studies of central 5-HTT availability have been inconsistent, which is thought to be brought about mainly by the low number of individuals with a high body mass index (BMI) previously used. The aim of this study was therefore to assess 5-HTT availability in the brains of highly obese otherwise healthy individuals compared with non-obese healthy controls. We performed PET using the 5-HTT selective radiotracer [{sup 11}C] DASB on 30 highly obese (BMI range between 35 and 55 kg/m{sup 2}) and 15 age- and sex-matched non-obese volunteers (BMI range between 19 and 27 kg/m{sup 2}) in a cross-sectional study design. The 5-HTT binding potential (BP{sub ND}) was used as the outcome parameter. On a group level, there was no significant difference in 5-HTT BP{sub ND} in various cortical and subcortical regions in individuals with the highest BMI compared with non-obese controls, while statistical models showed minor effects of age, sex, and the degree of depression on 5-HTT BP{sub ND}. The overall finding of a lack of significantly altered 5-HTT availability together with its high variance in obese individuals justifies the investigation of individual behavioral responses to external and internal cues which may further define distinct phenotypes and subgroups in human obesity.

    Recent evidence shows that certain microRNAs (miRNAs) play a role in both obesity and prostate cancer recurrence,but the association between the expression of these miRNAs and obesity in prostate cancer recurrence is unknown.In this study,we examined the effect of the interaction between obesity and miR-21,miR-221 or miR-222 expression on prostate cancer recurrence among 28 recurrent and 37 non-recurrent prostate cancer cases,miRNA expression was determined using quantitative real-time polymerase chain reaction.Cox proportional hazard models adjusting for age at diagnosis,clinical stage and Gleason score were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for recurrence free survival.A significantly (P=0.014) higher proportion of recurrent cases (78.6%) than non-recurrent cases (48.6%) had a low expression of miR-21 and the difference was more prominent in obese than non-obese patients.Multivariate analysis showed that the expression of miR-21 was an independent risk factor for recurrence in obese (HR=6.15,95% CI=1.04-36.48,P=0.045),but not in non-obese (HR=1.28,95% CI=0.30-5.49,P=0.74) cases.A significant association with recurrence was not observed for the expression of miR-221 and miR-222.In summary,our findings show that miR-21 is associated with prostate cancer recurrence after radical prostatectomy and suggest that the differential expression of miR-21 is more prominent in obese than in non-obese cases.Future larger studies are warranted to confirm these initial findings and to elucidate the mechanisms involved.

    Full Text Available High fat meals induce oxidative stress, which is associated with the pathogenesis of disease. Obese individuals have elevated resting biomarkers of oxidative stress compared to non-obese. We compared blood oxidative stress biomarkers in obese (n = 14; 30 ± 2 years; BMI 35 ± 1 kg•m−2 and non-obese (n = 16; 24 ± 2 years; BMI 23 ± 1 kg•m−2 women, in response to a high fat meal. Blood samples were collected pre-meal (fasted, and at 1, 2, 4 and 6 hours post meal, and assayed for trolox equivalent antioxidant capacity (TEAC, xanthine oxidase activity (XO, hydrogen peroxide (H2O2, malondialdehyde (MDA, triglycerides (TAG, and glucose. An obesity status effect was noted for all variables (p 0.05, contrasts revealed greater values in obese compared to non-obese women for XO, H2O2, MDA, TAG and glucose, and lower values for TEAC at times from 1–6 hours post feeding (p ≤ 0.03. We conclude that young, obese women experience a similar pattern of increase in blood oxidative stress biomarkers in response to a high fat meal, as compared to non-obese women. However, the overall oxidative stress is greater in obese women, and values appear to remain elevated for longer periods of time post feeding. These data provide insight into another potential mechanism related to obesity-mediated morbidity.

    Insulin-dependent diabetes mellitus is caused by autoimmune destruction of the insulin-producing beta cells of the pancreas. The results described here indicate that a beta-cell target antigen in non-obese diabetic (NOD/Lt) mice is a molecule cross-reactive with the 65-kDa heat shock protein (hsp65) of Mycobacterium tuberculosis. The onset of beta-cell destruction is associated with the spontaneous development of anti-hsp65 T lymphocytes. Subsequently hsp65 cross-reactive antigen becomes dete...

    The objective of this study was to examine provider adherence to prenatal care (PNC) content in obese and non-obese women and perinatal outcomes in obese women experiencing low and medium versus high adherence to PNC content. Provider adherence to PNC content (low obese (n = 69) and non-obese (n = 128) women in a linked database of deliveries to low-income, minority women from 2003 to 2004. Sample content items included procedures delivered at every visit (blood pressure, urinalysis, maternal weight, fetal heart rate check), timed screenings for birth defects and gestational diabetes, prenatal vitamin prescriptions, and depression screening. Weight gain, preterm deliveries, cesareans, and birthweight were compared between obese women with low and medium versus high adherence to PNC content using multivariable logistic regression. High provider adherence to an eight-item PNC content score (56.3 vs. 66.5%, p = 0.02) and depression screening (2.0 vs. 11.4%, p = 0.001) were both lower for obese versus non-obese women. Among obese women, there were no differences by level of provider adherence to PNC content in preterm delivery, cesareans, and low birth weight, but obese women experiencing low and medium versus high adherence were more likely to gain ≥20 lbs (aOR 5.5, 95% CI 1.3-23.3). Providers may be administering PNC differently to obese and non-obese women. PNC for obese women who are at high risk of adverse perinatal outcomes needs to be addressed especially as it relates to depression screening and gestational weight gain.

    Electronic-based (e-based) lifestyle interventions provide potential and cost-effective delivery of remote interventions for overweight and obese perinatal women. To date, no meta-analysis has reported the efficacy of maternal and neonatal outcomes. Seven electronic databases were searched from inception up to July 13, 2016, including the Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, EMBASE, ProQuest Dissertations and Theses, PsycINFO, PubMed and Scopus. Among the 1,145 studies retrieved, 14 randomized controlled trials were selected among 17 publications. The Cochrane risk of bias tool was used to appraise the quality assessment. The meta-analyses demonstrated a significant result for limiting gestational weight gain, losing postnatal weight in 1-2 months, increasing self-reported moderate and vigorous physical activity and reducing caloric intake using diet-related software. Our review shows that an e-based lifestyle intervention is an acceptable approach. The findings reveal the variability in intervention methods and provide limited conclusive evidence. Thus, future studies should examine the efficacy and essential components as well as the various approaches using optimal portions of in-person and phone sessions. Further evaluations comparing the effectiveness of different e-based lifestyle intervention approaches toward activity-related and diet-related outcomes are necessary. © 2017 World Obesity Federation.

    The characterization of the epigenetic changes within the obesity-related adipose tissue will provide new insights to understand this metabolic disorder, but adipose tissue is not easy to sample in population-based studies. We aimed to evaluate the capacity of circulating leukocytes to reflect the adipose tissue-specific DNA methylation status of obesity susceptibility. DNA samples isolated from subcutaneous adipose tissue and circulating leukocytes were hybridized in the Infinium HumanMethylation 450 BeadChip. Data were compared between samples from obese (n = 45) and non-obese (n = 8–10) patients by Wilcoxon-rank test, unadjusted for cell type distributions. A global hypomethylation of the differentially methylated CpG sites (DMCpGs) was observed in the obese subcutaneous adipose tissue and leukocytes. The overlap analysis yielded a number of genes mapped by the common DMCpGs that were identified to reflect the obesity state in the leukocytes. Specifically, the methylation levels of FGFRL1, NCAPH2, PNKD and SMAD3 exhibited excellent and statistically significant efficiencies in the discrimination of obesity from non-obesity status (AUC > 0.80; p < 0.05) and a great correlation between both tissues. Therefore, the current study provided new and valuable DNA methylation biomarkers of obesity-related adipose tissue pathogenesis through peripheral blood analysis, an easily accessible and minimally invasive biological material instead of adipose tissue.

Não foram encontradas diferenças no gasto energético de repouso entre os grupos, porém a potência aeróbia foi maior nos eutróficos. A dieta de ambos os grupos não foi considerada saudável, mas os obesos apresentaram menor consumo de vários alimentos considerados saudáveis, como hortaliças. Observou-se discrepância na análise do gasto energético diário, quando se adotaram diferentes métodos. CONCLUSÕES: Os adolescentes apresentaram padrão alimentar associado ao risco de obesidade e doenças crônicas. Mais estudos são necessários para identificar melhores métodos para avaliar seu gasto energético. É urgente a busca de estratégias de educação nutricional específicas para esse grupo etário.OBJECTIVE: To compare food consumption and energy expenditure between obese and non-obese adolescents. METHODS: This cross-sectional study comprised 23 adolescents recruited from schools and recreation centers from São Paulo (SP, Brazil, distributed in two groups: 11 obese and 12 non-obese. The following variables were analyzed: body weight, height, body mass index, waist circumference, fat and lean mass

    This cohort study of 725 women examined the health, occupational, and social factors that contribute to quitting work in two transnational electronics maquiladoras (assembly plants) in Tijuana, Mexico. The estimated cumulative probabilities of quitting were 68% and 81% by 1 and 2 years of employment. After adjusting for other factors, women who had a history of smoking or surgery and those who returned to work after a paid leave due to illness were more likely to quit. In contrast, women with a history of chronic illness had lower quitting rates. The nationality of the company and the work shift also significantly influenced quitting rates, but demographic characteristics and health care visits did not have a significant effect. Women selectively leave maquiladora employment, often due to health-related events. The healthy worker effect is difficult to measure in a mobile population with high turnover.

    Objectives: To measure serum and follicular resistin, steroids hormone levels in women with PCOS (polycystic ovary syndrome) (BMI (body mass index)<25 kg/m2), to assess possible correlations of resistin to hormonal and metabolic parameters and to analyze the clinical outcomes of in vitro fertilization-embryo transfer (IVF-ET) in women with PCOS and tubal infertility. Study design: We analyzed the clinical outcomes of IVF-ET in women with PCOS (BMI<25 kg/m2) and tubal infertility during the years 2002 to 2004 and compared the serum and follicular fluid resistin levels, estradiol (E2), progesterone (P), testosterone (T)levels in 20 PCOS and 20 healthy, age-matched women without PCOS during IVF-stimulated cycles. The correlations between the resistin levels and the outcomes of IVF-ET were evaluated. Results: No significant differences in resistin levels of either serum or follicular fluid between PCOS and control group were found. However, resistin levels in serum were higher than that in follicular fluid in both groups. Multiple regression analysis showed that resistin levels in serum did not correlate with BMI, estradiol, LH (luteinizing hormone) and insulin level in fasting blood. No significant correlations were found between follicular fluid reisistin levels and fertilization rate, implantation rate, clinical pregnancy rate or early miscarriage rate in both PCOS and control groups.Conclusion: Our results show that resistin does not have correlation with the hormonal and metabolic parameters as well as the outcomes of IVF. These data suggest that resistin is unlikely to be a local determinant factor in steroidogenesis and growth and maturation of oocytes during IVF-ET in lean women with PCOS.

  9. Insulin resistance in non-obese subjects is associated with activation of the JNK pathway and impaired insulin signaling in skeletal muscle.

    Full Text Available BACKGROUND: The pathogenesis of insulin resistance in the absence of obesity is unknown. In obesity, multiple stress kinases have been identified that impair the insulin signaling pathway via serine phosphorylation of key second messenger proteins. These stress kinases are activated through various mechanisms related to lipid oversupply locally in insulin target tissues and in various adipose depots. METHODOLOGY/PRINCIPAL FINDINGS: To explore whether specific stress kinases that have been implicated in the insulin resistance of obesity are potentially contributing to insulin resistance in non-obese individuals, twenty healthy, non-obese, normoglycemic subjects identified as insulin sensitive or resistant were studied. Vastus lateralis muscle biopsies obtained during euglycemic, hyperinsulinemic clamp were evaluated for insulin signaling and for activation of stress kinase pathways. Total and regional adipose stores and intramyocellular lipids (IMCL were assessed by DXA, MRI and (1H-MRS. In muscle of resistant subjects, phosphorylation of JNK was increased (1.36±0.23 vs. 0.78±0.10 OD units, P<0.05, while there was no evidence for activation of p38 MAPK or IKKβ. IRS-1 serine phosphorylation was increased (1.30±0.09 vs. 0.22±0.03 OD units, P<0.005 while insulin-stimulated tyrosine phosphorylation decreased (10.97±0.95 vs. 0.89±0.50 OD units, P<0.005. IMCL levels were twice as high in insulin resistant subjects (3.26±0.48 vs. 1.58±0.35% H(2O peak, P<0.05, who also displayed increased total fat and abdominal fat when compared to insulin sensitive controls. CONCLUSIONS: This is the first report demonstrating that insulin resistance in non-obese, normoglycemic subjects is associated with activation of the JNK pathway related to increased IMCL and higher total body and abdominal adipose stores. While JNK activation is consistent with a primary impact of muscle lipid accumulation on metabolic stress, further work is necessary to determine the

    Obesity is a growing epidemic around the world, and obese patients are generally regarded as high risk for surgery compared with normal weight patients. The purpose of this study was to evaluate the influence of obesity on the surgical outcomes of laparoscopic gastrectomy (LG) for gastric cancer. We reviewed data for all patients undergoing LG for gastric cancer at our institute between October 2004 and December 2016. Patients were divided into non-obese and obese groups and the perioperative outcomes were compared. Furthermore, a subgroup analysis was conducted to evaluate which of the two commonly used methods of LG, laparoscopic-assisted gastrectomy (LAG) and totally laparoscopic gastrectomy (TLG), is more suitable for obese patients. A total of 1691 patients, 1255 non-obese and 436 obese or overweight patients, underwent LG during the study period. The mean operation time was significantly longer in the obese group than in the non-obese group (209.9 ± 29.7 vs. 227.2 ± 25.7 min, P obese group (113.4 ± 34.1 vs. 136.9 ± 36.7 ml, P obese group than in the obese group (3.3 ± 0.8 vs. 3.6 ± 0.9 days; 4.3 ± 1.0 vs. 4.6 ± 1.0 days; and 9.0 ± 2.2 vs. 9.6 ± 2.2 days, respectively; P obese patients had postoperative complications as compared to 44 (10.1%) of the obese patients (P = 0.71). In the subgroup analysis of all patients, TLG showed improved results for early surgical outcomes compared to LAG, mainly due to its advantages in obese patients. Obesity is associated with long operation time, increased blood loss, and slow recovery after laparoscopic gastric resection but does not affect intraoperative security or effectiveness. TLG may have less negative results in obese patients than LAG due to a variety of reasons. Our analysis shows that TLG is more advantageous, with regard to early surgical outcomes, for obese patients.

    The objective of this work was to describe the anatomy of placentas from women who were at risk of exposure to parathion during their pregnancy, when examined with the light and scanning electron microscopes. Twenty term placentas were analyzed; 10 from women living in an agricultural area, who were at risk of exposure to parathion during their pregnancy, and 10 from women living in an urban area, not expressly exposed to pesticides. Each sample was examined with both light and scanning electron microscopes. Cholinesterase activity was significantly reduced in blood from women of the exposed group. In some placentas of women exposed to parathion, recent microinfarctions, microcalcifications and increased deposition of fibrinoid material were seen, along with a larger proportion of atypical characteristics of villi, such as bullous and balloon-like formations with nonhomogeneous surface, and other areas devoid of microvilli. These observations suggest that in chronic exposure to pesticides, the rate of atypical characteristics of placental villi increases, which could be related to changes in the fetus biology. In this study, one newborn from the exposed group showed intrauterine growth retardation and another one, some signs of hypoxia.

    Since the discovery of therapeutic insulin in 1922 and the development of the non-obese diabetic spontaneous mouse model in 1980,the establishment of Network for Pancreatic Organ Donor with Diabetes(n POD) in 2007 is arguably the most important milestone step in advancing type 1 diabetes(T1D) research. In this perspective,we briefly describe how n POD is transforming T1 D research via procuring and coordinating analysis of disease pathogenesis directly in human organs donated by deceased diabetic and control subjects. The successful precedent set up by n POD is likely to spread far beyond the confines of research in T1 D to revolutionize biomedical research of other disease using high quality procured human cells and tissues.

    Full Text Available Abstract Background The Malaysian Ministry of Health promotes breast self-examination (BSE for all women, and Pap smear screening every three years for all sexually active women ages 20 years and above. The objectives of this paper were to examine the practice of these two screening tests among women production workers in electronics factories, and to identify factors related to practice. Methods This was a cross-sectional survey of women production workers from ten electronics factories. Data was collected by a self-administered questionnaire from a total of 1,720 women. The chi-square test, odds ratio and binomial logistic regression were used in bivariate and multivariate analysis. Results Prevalence rates were 24.4% for BSE once a month, and 18.4% for Pap smear examination within the last three years. Women who were significantly more likely to perform BSE every month were 30 years and older, Malays, with upper secondary education and above, answered the BSE question correctly, and had a Pap smear within the last three years. The proportion of women who had a Pap smear within the last three years were significantly higher among those who were older, married, with young children, on the contraceptive pill or intra-uterine device, had a medical examination within the last five years, answered the Pap smear question correctly, and performed BSE monthly. Conclusion Screening practice rates in this study were low when compared to national rates. Socio-demographic and health care factors significantly associated with screening practice are indicative of barriers which should be further understood so that more effective educational and promotional strategies could be developed.

    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.

    The study was aimed to assess paraoxonase-1 (PON1) activity, pleiotropic effects of simvastatin, and its relationship to Q192R and M55L polymorphisms in obese and non-obese subjects with stable coronary artery disease (CAD). The study included 53 subjects (22 obese) aged from 35 to 65 years with CAD. The control group consisted of 53 (18 obese) police officers without CAD. Patients with CAD were treated with simvastatin 40 mg/day for 12 months. The lipid profile, flow mediated dilation (FMD), intima media-thickness (IMT), fibrinogen, hs-CRP, TNF-α, urine 8-iso-PGF2α, and PON1 activity were evaluated in definite time points. PON1 polymorphisms were assessed at baseline in all observed individuals. The patients with CAD and obesity presented at baseline significantly increased hs-CRP level, insignificantly decreased FMD and lower PON1 activity compared to non-obese individuals. There was no association of obesity with 8-iso-PGF2α in the CAD and control group. The PON1 activity was significantly higher in 192R carriers in patients and controls, irrespective of obesity. Obesity was not associated with the effects of simvastatin on PON1 activity, urine 8-iso-PGF2α, and TNF-α, whereas it blunted its effect on the FMD improvement. The Q192R polymorphism was associated with simvastatin effectiveness on hs-CRP and FMD. Obesity and Q192R PON1 polymorphism are significantly associated with pleiotropic effects of simvastatin therapy in patients with stable CAD.

    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.

    The objectives of this study were to compare, by patient obesity status, the contemporary utilization patterns of different reconstruction surgery types, understand postoperative complication profiles in the community setting, and analyze the financial impact on health care payers and patients. Using data from the MarketScan Health Risk Assessment Database and Commercial Claims and Encounters Database, we identified breast cancer patients who received breast reconstruction surgery following mastectomy between 2009 and 2012. The Cochran-Armitage test was used to evaluate the utilization pattern of breast reconstruction surgery. Multivariable logistic regressions were used to estimate the association between obesity status and infectious, wound, and perfusion complications within one year of surgery. A generalized linear model was used to compare total, complication-related, and out-of-pocket costs. The rate of TE/implant-based reconstruction increased significantly for non-obese patients but not for obese patients during the years analyzed, whereas autologous reconstruction decreased for both patient groups. Obesity was associated with higher odds of infectious, wound, and perfusion complications after TE/implant-based reconstruction, and higher odds of perfusion complications after autologous reconstruction. The adjusted total healthcare costs and out-of-pocket costs were similar for obese and non-obese patients for either type of breast reconstruction surgery. A greater likelihood of one-year complications arose from TE/implant-based vs autologous reconstruction surgery in obese patients. Given that out-of-pocket costs were independent of the type of reconstruction, greater emphasis should be placed on conveying the surgery-related complications to obese patients to aid in patient-based decision making with their plastic surgeons and oncologists.

    Cerebral serotonin metabolism has an important but controversial role in obesity. However, it is not given enough attention in morbidly obese young adults. We used single photon emission computed tomography (SPECT) with [I-123]-labeled 2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine (ADAM) to investigate changes in serotonin transporter (SERT) availability in 10 morbidly obese young adults without an eating disorder (M/F = 5/5, body mass index (BMI): 40.3 ± 4.1 kg/m2, percentage of body fat (BF%): 46.0 ± 3.9%) and 10 age- and sex-matched non-obese controls (BMI: 20.3 ± 1.2 kg/m2, BF%: 20.6 ± 8.9%). All participants underwent SPECT at 10 min and 6 h after an injection of 200 MBq of [I-123]-ADAM. The SERT binding site (midbrain) was drawn with cerebellum normalization. The BF% and fat distribution were measured using dual-energy X-ray absorptiometry. The midbrain/cerebellum SERT binding ratios (2.49 ± 0.46 vs. 2.47 ± 0.47; p = 0.912) at 6 h were not significantly different between groups, nor was the distribution of the summed images at 10 min (1.36 ± 0.14 vs. 1.35 ± 0.11; p = 0.853). There were no significant correlations between midbrain/cerebellum SERT binding ratio and age, BMI, BF%, or fat distribution. No significant difference in SERT availability in the midbrain between morbidly obese and non-obese young adults without an eating disorder indicates an unmet need for investigating the role of cerebral serotonin in obesity.

    The aim of the present study was to evaluate the effectiveness of the combined administration of myo-inositol and α-lipoic acid in polycystic ovary syndrome (PCOS) patients with normal body mass index (BMI), who had previously undergone intracytoplasmic sperm injection (ICSI) and received myo-inositol alone. Thirty-six of 65 normal-weight patients affected by PCOS who did not achieve pregnancy and one patient who had a spontaneous abortion were re-enrolled and given a cycle of treatment with myo-inositol and α-lipoic acid. For all female partners of the treated couples, the endocrine-metabolic and ultrasound parameters, ovarian volume, oocyte and embryo quality, and pregnancy rates were assessed before and after three months of treatment and compared with those of previous in vitro fertilization (IVF) cycle(s). After supplementation of myo-inositol with α-lipoic acid, insulin levels, BMI and ovarian volume were significantly reduced compared with myo-inositol alone. No differences were found in the fertilization and cleavage rate or in the mean number of transferred embryos between the two different treatments, whereas the number of grade 1 embryos was significantly increased, with a significant reduction in the number of grade 2 embryos treated with myo-inositol plus α-lipoic acid. Clinical pregnancy was not significantly different with a trend for a higher percentage for of myo-inositol and α-lipoic acid compared to the myo-inositol alone group. Our preliminary data suggest that the supplementation of myo-inositol and α-lipoic acid in PCOS patients undergoing an IVF cycle can help to improve their reproductive outcome and also their metabolic profiles, opening potential for their use in long-term prevention of PCOS.

    Full Text Available BACKGROUND Polycystic Ovary Syndrome (PCOS is one of the most common endocrinopathy in premenopausal women. AIM The aim of the study was to evaluate the effectiveness of the Poincare plot analysis of Heart Rate Variability (HRV in PCOS. METHODS AND MATERIALS 24 PCOS diagnosed by Rotterdam 2003 Diagnostic Criteria and were of lean and ideal weight as per WHO criteria and 24 BMI matched, age matched normally menstruating women served as study participants. People of the study group underwent 5 min of ECG, which was evaluated for HRV. HRV analysed were Geometrical parameters (HRV, TRI, INDEX, TINN, Total Power (TP and Poincare plot parameters (SD1, SD2, SD1/SD2, S. RESULTS The Poincare scatter grams were narrower in patients and wider in control groups showing parasympathetic withdrawal and sympathetic dominance, but were not statistically significant. Area (S, TP and HRV TRI INDEX, TINN showed overall decrease in autonomic activity denoting altered sympathovagal balance favouring sympathetic dominance. There was a significant correlation of TP, SD1, SD2, S, TINN and HRV TRI INDEX with increased Rate Pressure Product (RPP as well as with one another, but not with BMI. The regression analysis did not lay forward the independent associations of these variables. DISCUSSION AND CONCLUSION This study indicates the total variability is decreased even in young, lean and ideal weight PCOS patients. Larger studies are needed to evaluating the short- and long-term variability.

    The impact of the age and sex adjusted body mass index (ISO-BMI) in the obese vs. non-obese children and adolescents with cholecystectomy for cholelithias is rarely reported. The national database was searched for cholecystectomies performed in paediatric patients between 1997 and 2011, and the 59 paediatric and adolescent patients having cholecystectomy in the Kuopio University Hospital district were divided in two groups by age and sex adjusted BMI (ISO-BMI) using the cut-off point of overweight (ISO-BMI 25 kg/m(2)) based on the Finnish growth standards. Nationwide a total of 840 cholecystectomies were performed during the 15 years study period in Finland, most of which included females (77%), resulting in a mean of annual frequency of 4.8 (range: 3.9-6.1) procedures/100,000 population. In the study sample, most of the patients with the cholelithiasis were female (50/59, 85%). The gender distribution was equal among the younger patients, but among adolescents 6/52 (12%) of the patients with cholelithiasis were boys and 46/52 (88%) of the patients with cholelithiasis were girls. Obesity did not affect on operative parameters. The median operative time was 70 min (range, 30-155) and 66 min (44-130) in the high ISO-BMI-group. The recovery was similar in the two groups: the median length of hospital stay was 4 days in both groups. The patients in the low ISO-BMI-group vs. high ISO-BMI-group had a trend of higher serum bilirubin (p=0.16) and serum AFOS values (p=0.19).

    Polycystic ovary syndrome (PCOS) is one of the most common hormonal endocrine disorders in women of reproductive age. It consists of a heterogeneous collection of signs and symptoms that together form a disorder spectrum. The diagnosis of PCOS is principally based on clinical and physical findings. The extent of metabolic abnormalities in women with PCOS varies with phenotype, body weight, age, and ethnicity. For general population, the prevalence of hyperandrogenism and oligomenorrhea decreases with age, while complications such as insulin resistance and other metabolic disturbances increase with age. Obese women with PCOS have a higher risk of developing oligomenorrhea, amenorrhea, hyperandrogenemia, insulin resistance, and lower luteinizing hormone (LH) to follicle stimulation hormone (FSH) ratios than non-obese women with PCOS. The LH to FSH ratio is a valuable diagnostic tool in evaluating Taiwanese women with PCOS, especially in the diagnosis of oligomenorrhea. Overweight/obesity is the major determinant of cardiovascular and metabolic disturbances in women of reproductive age.

    Full Text Available Multiple sclerosis (MS is a neurodegenerative disease resulting from an autoimmune attack on central nervous system myelin. While CD4+ T cell function in MS pathology has been extensively studied, there is also strong evidence that CD8+ T lymphocytes play a key role. Intriguingly, CD8+ T cells accumulate in great numbers in the CNS in progressive MS, a form of the disease that is refractory to current disease-modifying therapies which target the CD4+ T cell response. Here, we discuss the function of CD8+ T cells in experimental autoimmune encephalomyelitis (EAE, a mouse model of MS. In particular, we describe EAE in non-obese diabetic (NOD background mice, which develop a pattern of disease characterized by multiple attacks and remissions followed by a progressively worsening phase. This is highly reminiscent of the pattern of disease observed in nearly half of MS patients. Particular attention is paid to a newly described transgenic mouse strain (1C6 on the NOD background whose CD4+ and CD8+ T cells are directed against the encephalitogenic peptide MOG[35-55]. Use of this model will give us a more complete picture of the role(s played by distinct T cell subsets in CNS autoimmunity.

    The objective of the present study was to utilise an accurate canine pedometer methodology and to assess the relationship between activity and body condition score (BCS) in dogs. Initial methodology validation used videography and pedometer step measurements to assess actual steps taken in comparison with pedometer readings for twenty large, medium and small dogs. During the validation, dogs considered to be medium or large breed showed no significant difference between pedometer readings and actual steps taken. A total of seventy-seven obese and non-obese dogs over 35 cm (14 inches) shoulder height and over 10 kg were recruited from a dog obesity clinic and a community sample to assess daily walking activity. Body condition scoring and pedometer steps were assessed on three separate weeks during a 10-week period. During the activity monitoring, daily step counts ranged from 5555 to 39 970 steps/d among the seventy-seven medium and large dogs. Dogs' BCS were inversely correlated with average daily steps (Spearman's ρ = - 0.442, P < 0.0001). The present study identified a significant inverse correlation between daily walking steps and BCS over a range from 4 to 9 out of 9 (P < 0.0001).

    The intestinal microbiota is important for tolerance induction through mucosal immunological responses. The composition of the gut microbiota of an infant is affected by environmental factors such as diet, disease and antibiotic treatment. However, already in utero, these environmental factors can affect the immunological development of the foetus and influence the future gut microbiota of the infant. To investigate the effects of antibiotic treatment of pregnant mothers on the offspring's gut microbiome and diabetes development, we treated non-obese diabetic (NOD) mice with a cocktail of antibiotics during gestation and the composition of the gut microbiota, diabetes incidence and major gut-related T lymphocyte populations were investigated in the offspring. We observed a persistent reduction in the general diversity of the gut microbiota in the offspring from NOD mothers treated with antibiotics during gestation compared with offspring from control mothers. In addition, by clustering the present bacterial taxa with principal component analysis, we found a differential clustering of gut microbiota in the offspring from NOD mothers treated with antibiotics during gestation compared with offspring from control mothers. Offspring from NOD mothers treated with antibiotics during gestation also showed some immunological alterations in the gut immune system, which could be related to the diversity of the gut microbiome and influence modulation of diabetes development at 20 weeks. Our data point out maternal derangement of the intestinal microbiota as a potential environmental risk factor for T1D development.

    Adoptive cell therapy with lymphocytes that have been genetically engineered to express tumor-reactive T-cell receptors (TCR) is a promising approach for cancer immunotherapy. We have been exploring the development of TCR gene therapy targeting cancer/testis antigens, including melanoma-associated antigen (MAGE) family antigens, that are ideal targets for adoptive T-cell therapy. The efficacy of TCR gene therapy targeting MAGE family antigens, however, has not yet been evaluated in vivo. Here, we demonstrate the in vivo antitumor activity in immunodeficient non-obese diabetic/SCID/γc(null) (NOG) mice of human lymphocytes genetically engineered to express TCR specific for the MAGE-A4 antigen. Polyclonal T cells derived from human peripheral blood mononuclear cells were transduced with the αβ TCR genes specific for MAGE-A4, then adoptively transferred into NOG mice inoculated with MAGE-A4 expressing human tumor cell lines. The transferred T cells maintained their effector function in vivo, infiltrated into tumors, and inhibited tumor growth in an antigen-specific manner. The combination of adoptive cell therapy with antigen peptide vaccination enhanced antitumor activity, with improved multifunctionality of the transferred cells. These data suggest that TCR gene therapy with MAGE-A4-specific TCR is a promising strategy to treat patients with MAGE-A4-expressing tumors; in addition, the acquisition of multifunctionality in vivo is an important factor to predict the quality of the T-cell response during adoptive therapy with human lymphocytes.

    Full Text Available Osteoporosis in males is becoming an important health concern in an aging society. The aim of this study was to investigate the associations between cadmium exposure and osteoporosis by considering the effect of obesity in aged males using a representative sample of the Korean population. Using the fourth and fifth Korea National Health and Nutrition Examination Survey data, 1098 males over 50 years of age were analyzed. The blood cadmium concentration was measured. The bone mineral density in the total hip, femur neck, and lumbar spine was measured using dual-energy X-ray absorptiometry. T-scores to determine the presence of osteoporosis were calculated using a Korean reference. Subjects were stratified into two groups according to obesity status (body mass index <25 kg/m2 and ≥25 kg/m2. In comparison with obese subjects with blood cadmium <1.00 μg/L, those with blood cadmium >1.50 μg/L had odds ratios of 4.57 (95% confidence interval [CI] 1.49–14.01 and 5.71 (95% CI 1.99–16.38 at the femur neck and any site, respectively, after adjusting for potential confounders such as age, serum creatinine, vitamin D deficiency, smoking, alcohol drinking, and physical activity level. However, this association was not significant in non-obese males. In conclusion, the effect of cadmium on osteoporosis was different by obesity status in aged males.

    Full Text Available Intrauterine infection is one of the most frequent causes of miscarriage. CpG oligodeoxynucleotide (CpG ODN can mimic intrauterine infection. CpG ODN-induced embryo-resorption was observed consistently in the NK-cell deficient non-obese diabetic (NOD mice but not in the wild-type (WT mice. To elucidate the molecular mechanisms of differential pregnancy outcomes, differentially expressed genes (DEGs in the placenta and decidua basalis was revealed by RNA-Seq with CpG ODN or control ODN treatment. Common DEGs in the WT and NOD mice were enriched in antimicrobial/antibacterial humoral responses that may be activated as a primary response to bacterial infection. The susceptibility to CpG ODN-induced embryo-resorption in the NOD mice might mainly be attributed to M1 macrophage polarization and the immunodeficient status, such as the down-regulation in antigen processing and presentation, allograft rejection, and natural killer cell mediated cytotoxicity. In contrast, the WT mice with normal immune systems could activate multiple immune responses and be resistant to CpG ODN-induced embryo-resorption, such as M2 macrophage differentiation and activation regulated by complement component C1q and peroxisome proliferation-activated receptor (PPAR signaling pathways. Collectively, this study suggests that the immunodeficient status of NOD mice and the macrophage polarization regulated by C1q and PPAR signaling might be the basis for differential pregnancy outcomes between the NOD and WT mice.

    Recent studies have shown that autologous and allogeneic transplantation of the BM-MSCs had therapeutic effects on T1DM, whereas the BM-MSCs from the NOD mice itself did not have this therapeutic effect. We previously demonstrated that Bone Marrow (BM) -MSCs from the non-obese diabetic (NOD) mice had the abnormal migration and adhesion. So we hypothesized that the proliferation and apoptosis of the BM-MSCs from the NOD mice were dysregulated. Our team compared the proliferation and apoptosis between NOD mice and imprinting control region (ICR) mice. Then we assessed whether the NF-κB-p53/p21 pathway was involved in the process. The cell proliferation ability of the BM-MSCs from the NOD mice were significantly decreased, while the percent of apoptotic cells was increased compared to those from the ICR mice. The p21 expression was significantly increased in the NOD-MSCs. The p65 level was enhanced in the BM-MSCs from the NOD mice when compared to the ICR mice, coincided with the expression of p21. Expressions of p65 and p21 were significantly decreased in the -BM-MSCs treated with p65 inhibitor. The knockdown p21 expression reversed the abnormal proliferation, colony formation and apoptosis of the BM-MSCs from the NOD mice. These data provide important preclinical references supporting the basis for further development of autologous MSC-based therapies for type1 diabetes mellitus (T1DM).

  14. Alteration of the thymic T cell repertoire by rotavirus infection is associated with delayed type 1 diabetes development in non-obese diabetic mice.

    Nicole L Webster

    Full Text Available Rotaviruses are implicated as a viral trigger for the acceleration of type 1 diabetes in children. Infection of adult non-obese diabetic (NOD mice with rotavirus strain RRV accelerates diabetes development, whereas RRV infection in infant NOD mice delays diabetes onset. In this study of infant mice, RRV titers and lymphocyte populations in the intestine, mesenteric lymph nodes (MLN and thymus of NOD mice were compared with those in diabetes-resistant BALB/c and C57BL/6 mice. Enhanced intestinal RRV infection occurred in NOD mice compared with the other mouse strains. This was associated with increases in the frequency of CD8αβ TCRαβ intraepithelial lymphocytes, and their PD-L1 expression. Virus spread to the MLN and T cell numbers there also were greatest in NOD mice. Thymic RRV infection is shown here in all mouse strains, often in combination with alterations in T cell ontogeny. Infection lowered thymocyte numbers in infant NOD and C57BL/6 mice, whereas thymocyte production was unaltered overall in infant BALB/c mice. In the NOD mouse thymus, effector CD4(+ T cell numbers were reduced by infection, whereas regulatory T cell numbers were maintained. It is proposed that maintenance of thymic regulatory T cell numbers may contribute to the increased suppression of inflammatory T cells in response to a strong stimulus observed in pancreatic lymph nodes of adult mice infected as infants. These findings show that rotavirus replication is enhanced in diabetes-prone mice, and provide evidence that thymic T cell alterations may contribute to the delayed diabetes onset following RRV infection.

    Full Text Available It has been proposed that rotavirus infection promotes the progression of genetically-predisposed children to type 1 diabetes, a chronic autoimmune disease marked by infiltration of activated lymphocytes into pancreatic islets. Non-obese diabetic (NOD mice provide a model for the human disease. Infection of adult NOD mice with rhesus monkey rotavirus (RRV accelerates diabetes onset, without evidence of pancreatic infection. Rather, RRV spreads to the pancreatic and mesenteric lymph nodes where its association with antigen-presenting cells, including dendritic cells, induces cellular maturation. RRV infection increases levels of the class I major histocompatibility complex on B cells and proinflammatory cytokine expression by T cells at these sites. In autoimmunity-resistant mice and human mononuclear cells from blood, rotavirus-exposed plasmacytoid dendritic cells contribute to bystander polyclonal B cell activation through type I interferon expression. Here we tested the hypothesis that rotavirus induces bystander activation of lymphocytes from NOD mice by provoking dendritic cell activation and proinflammatory cytokine secretion. NOD mouse splenocytes were stimulated with rotavirus and assessed for activation by flow cytometry. This stimulation activated antigen-presenting cells and B cells independently of virus strain and replicative ability. Instead, activation depended on virus dose and was prevented by blockade of virus decapsidation, inhibition of endosomal acidification and interference with signaling through Toll-like receptor 7 and the type I interferon receptor. Plasmacytoid dendritic cells were more efficiently activated than conventional dendritic cells by RRV, and contributed to the activation of B and T cells, including islet-autoreactive CD8+ T cells. Thus, a double-stranded RNA virus can induce Toll-like receptor 7 signaling, resulting in lymphocyte activation. Our findings suggest that bystander activation mediated by type I

    We planned to investigate the expression of protein kinase C (PKC) isoforms in acinar epithelial cells of salivary glands in the non-obese diabetic (NOD) mouse to find out if they develop changes of the PKC system like those seen in the human counterpart, i.e. in Sjögren's syndrome. Parotid, submandibular, and sublingual glands from NOD and control BALB/c mice were stained with a panel of monoclonal antibodies directed against conventional (alpha, beta, and gamma), novel (delta, epsilon, and theta), and atypical (lambda and iota) PKC isoforms using the streptavidin/HRP method. Similarly to human labial salivary glands, acinar epithelial cells of the healthy control BALB/c mice contained two of the conventional PKC isoforms, alpha and beta. Acinar and ductal epithelial cells also contained the atypical PKC isoforms lambda and iota. PKC isoforms gamma, delta, epsilon, and theta were not found. NOD mice which displayed focal sialadenitis contained the same conventional and atypical PKC isoforms. The acinar cells in NOD mice, in contrast to the Sjögren's syndrome patients, did not lack PKC alpha or beta. On the contrary, PKC alpha and beta staining was stronger than in the control BALB/c mice. The present results demonstrate that both conventional and atypical PKC isoforms participate in the salivary epithelial cell biology and that there are mouse strain-associated and/or disease state-associated changes in their expression. The lack of PKC alpha and beta isoforms found in Sjögren's syndrome was not reproduced in NOD mice, which discloses one more difference between the human disease and its NOD mouse model.

    Dietary supplementation with complex carbohydrates is known to alter the composition of gut microbiota, and optimal implementation of the use of these so called “prebiotics” could be of great potential in prevention and possibly treatment of obesity and associated cardiometabolic and inflammatory diseases via changes in the gut microbiota. An alternative to this “microbiocentric view” is the idea that health-promoting effects of certain complex carbohydrates reside in the host, and could secondarily affect the diversity and abundance of gut microbiota. To circumvent this potential interpretational problem, we aimed at providing an overview about whether and how dietary supplementation of different complex carbohydrates changes the gut microbiome in healthy non-obese individuals. We then reviewed whether the reported changes in gut bacterial members found to be established by complex carbohydrates would benefit or harm the cardiometabolic and immunological health of the host taking into account the alterations in the microbiome composition and abundance known to be associated with obesity and its associated disorders. By combining these research areas, we aimed to give a better insight into the potential of (foods containing) complex carbohydrates in the treatment and prevention of above-mentioned diseases. We conclude that supplemental complex carbohydrates that increase Bifidobacteria and Lactobacilli, without increasing the deleterious Bacteroides, are most likely promoting cardiometabolic and immunological health in obese subjects. Because certain complex carbohydrates also affect the host’s immunity directly, it is likely that host–microbiome interactions in determination of health and disease characteristics are indeed bidirectional. Overall, this review article shows that whereas it is relatively clear in which direction supplemental fermentable carbohydrates can alter the gut microbiome, the relevance of these changes regarding health remains

    (-)-Epigallocatechin-3-gallate (EGCG), which is largely found in green tea, is known to eliminate reactive oxygen species and associated inflammatory responses in vitro and in cells. However, the in vivo mechanisms underlying the effects of EGCG on the amelioration of metabolic disorders are not fully understood. In this study, we examined whether dietary supplementation with EGCG reduces inflammatory responses in peripheral leukocytes of a non-obese type 2 diabetes animal model, Goto-Kakizaki (GK) rats. GK rats at 9 wk of age were fed a control high-fat diet (46 energy % from lard and corn oil) or a high-fat diet containing 0.1%, 0.2%, or 0.5% EGCG (w/w) for 25 wk. The oxidative stress markers 8-hydroxydeoxyguanosine (OHdG) and total malondialdehyde (MDA) were reduced by supplementation with EGCG at 0.1%, but not at 0.2% or more. Significant reductions in the mRNA levels of genes related to inflammatory responses (TNF-α, IFN-γ, IL-1β, IL-6, IL-18, MCP-1, CD11b, and S100a6), 8-OHdG, and total MDA were induced in peripheral leukocytes of GK rats by EGCG supplementation at 0.1%, but not at 0.2% or more, compared with rats fed the control diet. The present results suggest that supplementation with a low dose of EGCG reduces oxidative stress and the expressions of genes involved in inflammation in peripheral leukocytes of GK rats.

    Oxazolone-induced colitis in mice has become a recognized model to study the efficacy of therapeutics targeting the immunological response underlying the development of inflammatory bowel disease. However, this model cannot be used when therapeutics designed to address human targets do not interact with the respective murine counterpart. In this study, we examined the induction of oxazolone mediated colitis in non-obese diabetic-severe combined immunodeficiency interleukin-2Rγnull (NOD-SCID IL2Rγnull) mice engrafted with human peripheral blood mononuclear cells (hPBMC) derived from patients suffering from ulcerative colitis (UC), atopic dermatitis (AD) and healthy volunteers. NOD-SCID IL2Rγ null mice were engrafted with hPBMC followed by challenge with oxazolone or ethanol vehicle. Mice developed the same symptoms as observed previously in immunocompetent mice. The clinical activity score increased and the colon architecture was characterized by the development of oedema, fibrosis, crypt loss and dense infiltration of predominantly T cells into the lamina propria. Fluorescence activated cell sorter (FACS) analysis of lymphocytes in the colon identified natural killer (NK) T cells as a major constituent. In contrast to studies with immunocompetent mice, we observed the same phenotype in the group challenged with ethanol vehicle. The phenotype was most pronounced in mice engrafted with PBMC derived from a patient suffering from UC, suggesting that the immunological history of the donors predisposes the engrafted mice to react to ethanol. The model described here has the potential to study the efficacy of therapeutics targeting human lymphocytes in a model which is more reflective of the human disease. In addition, it might be developed to elucidate molecular mechanisms underlying the disease. PMID:23574330

    To determine if the relationship between obesity and usage of colorectal cancer (CRC) screening in women varies when stratifying by race. Using nationally representative data from the 2005 National Health Interview Survey, we examined the relationship between obesity and CRC screening for white and African-American women aged 50 and older. Screening usage variables indicated if a woman was up-to-date for any CRC screening test, colonoscopy, or FOBT. We used multivariable logistic regression models that included interaction terms to determine if race moderates the obesity-screening relationship. We also calculated adjusted up-to-date colonoscopy rates using direct standardization to model covariates. The relationship between obesity and screening differed by race for any CRC screening test (P = 0.04 for interaction) and for colonoscopy (P = 0.01 for interaction), but not for FOBT. Obese white women had a lower adjusted colonoscopy rate (30.2%, 95% CI 25.9-34.8) than non-obese white women (39.1%, 95% CI 36.1-42.2). Obese African-American women, on the other hand, had a higher adjusted colonoscopy rate (41.2%, 95% CI 31.6-51.4) than their non-obese counterparts (35.6%, 95% CI 28.3-43.6). Overall, adjusted colonoscopy rates were lowest among obese white women. Obesity is associated with lower CRC screening rates in white, but not African-American women.

    Obesity is a chronic inflammatory state characterized by altered adipokine production and increased levels of inflammatory cytokines. The study explored the effect of zinc supplementation on inflammatory markers and adipocyte hormones in young obese women. Twenty five non-obese women and forty obese women (body mass index ≥25 kg/m(2)) aged 19-28 years were recruited for this study. Twenty obese women of the study group took 30 mg/day of supplemental zinc as zinc gluconate for 8 weeks and 20 obese women of control group took placebo. Usual dietary zinc intake was estimated from 3-day diet records. Serum zinc and urinary zinc concentration were measured by Atomic Absorption Spectrophotometry. Inflammatory markers such as high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), and interleukin (IL)-6 and adipocyte hormones such as lepin and adiponectin were measured by enzyme immunoassay. Inflammatory markers and leptin were significantly higher, but adiponectin was significantly lower in obese women than non-obese women. Zinc supplementation increased serum zinc by 15% and urinary zinc by 56% (P zinc supplementation, but not in placebo group. Serum leptin and plasma adiponectin concentration did not differ with either zinc supplementation or placebo. The levels of IL-6 and leptin were inversely associated with dietary zinc intake. These results suggest that zinc may have a favorable effect on obesity-related inflammation in young adults.

    Background Excessive iodine intake and viral infection are recognized as both critical factors associated with autoimmune thyroid diseases.Toll-like receptors (TLRs) have been reported to play an important role in autoimmune and inflammatory disorders.In this study,we aimed to clarify the possible mechanism of TLR3 involved in polyinosinepolycytidylic acid (poly(l:C)) promoting excessive iodine intake induced thyroiditis in non-obese diabetic (NOD) mice.Methods Both NOD and BALB/c mice were randomly assigned to four groups:control group (n=5),high iodine intake (HI) group (n=7),poly(l:C) group (n=7) and combination of excessive iodine and poly(l:C) injection (HIP) group (n=7).After 8 weeks,mice were weighed and blood samples were collected.All the mice were sacrificed before dissection of spleen and thyroid gland.Then,thyroid histology,thyroid secreted hormone,expression of CD3+ cells and TLR3 as well as inflammatory mRNA level were evaluated.Results Both NOD and BALB/c mice from HI and HIP group represented goiter and increasing thyroid relative weight.Thyroid histology evidence indicated that only HIP group of NOD mice showed severe thyroiditis with lymphocytes infiltration in majority of thyroid tissue,severe damage of follicles and general fibrosis.Immunofluorescence staining results displayed a large number of CD3+ cells in HIP NOD mice.Real-time polymerase chain reaction (PCR) results suggested interferon (IFN)-αincreased over 30 folds and IFN-γ expression was doubled compared with control group,but interleukin (IL)-4 remained unchanged in HIP group of NOD mice thyroid.Meanwhile,over one third decrease of blood total thyroxine (TT4) and increased thyroid-stimulating hormone (TSH) was observed in HIP group of NOD mice.Only HIP group of NOD mice represented significantly elevation of TLR3 expression.Conclusion Poly(l:C) enhanced excessive dietary iodine induced thyroiditis in NOD mice through increasing TLR3 mediated inflammation.

    Full Text Available Objective To investigate the changes in Th1 cells and CD4+CD25+Treg cells in non-obese diabetic (NOD mice at early stage of diabetes, and to evaluate the significance of these changes. Methods Four week- (group A, 8 week- (group B and 16 week-old (group C female NOD mice (8 each were used in present study. The spleen, thymus and pancreas were harvested. Th1 and CD4+CD25+Treg cells in spleen were determined by flow cytometer, and the ratios of Th1/CD4+T, CD4+CD25+Treg/CD4+T and Th1/CD4+CD25+Treg were calculated. Subsequently, CD4–CD8–T, CD4+CD8+T, CD4–CD8+T and CD4+CD8–T cells in thymus were determined by flow cytometer, and the ratio of CD25+Treg/CD4+CD8–T was calculated. The histopathological changes in pancreas were also evaluated by HE staining and immunohistochemistry staining. Results The proportion of Th1 cells in spleen and the ratios of Th1/CD4+T and Th1/CD4+CD25+Treg were higher significantly in group C than in group A and B. However, no significant differences were found in the proportion of spleen CD4+CD25+Treg cells and the ratio of CD4+CD25+Treg/CD4+T among the three groups. Compared with group A, no obvious changes were found in thymus CD4–CD8–T, CD4+CD8+T, CD4–CD8+T and CD4+CD8–T cells in group B and C, but the ratio of thymus CD25+Treg/CD4+CD8–T increased significantly in group B and C. Lymphocytic infiltration was observed in pancreatic islets of group B and C as shown with HE staining, but Foxp3+T cells were not seen in pancreatic islets by immunohistochemistry. Conclusion Th1 cells are gradually increased at early stage of diabetes in NOD mice, but CD4+CD25+Treg cells are relatively default. These changes may play an important role in the progress of diabetes. DOI: 10.11855/j.issn.0577-7402.2013.11.004

  6. IL-2 immunotherapy reveals potential for innate beta cell regeneration in the non-obese diabetic mouse model of autoimmune diabetes.

    Full Text Available Type-1 diabetes (T1D is an autoimmune disease targeting insulin-producing beta cells, resulting in dependence on exogenous insulin. To date, significant efforts have been invested to develop immune-modulatory therapies for T1D treatment. Previously, IL-2 immunotherapy was demonstrated to prevent and reverse T1D at onset in the non-obese diabetic (NOD mouse model, revealing potential as a therapy in early disease stage in humans. In the NOD model, IL-2 deficiency contributes to a loss of regulatory T cell function. This deficiency can be augmented with IL-2 or antibody bound to IL-2 (Ab/IL-2 therapy, resulting in regulatory T cell expansion and potentiation. However, an understanding of the mechanism by which reconstituted regulatory T cell function allows for reversal of diabetes after onset is not clearly understood. Here, we describe that Ab/IL-2 immunotherapy treatment, given at the time of diabetes onset in NOD mice, not only correlated with reversal of diabetes and expansion of Treg cells, but also demonstrated the ability to significantly increase beta cell proliferation. Proliferation appeared specific to Ab/IL-2 immunotherapy, as anti-CD3 therapy did not have a similar effect. Furthermore, to assess the effect of Ab/IL-2 immunotherapy well after the development of diabetes, we tested the effect of delaying treatment for 4 weeks after diabetes onset, when beta cells were virtually absent. At this late stage after diabetes onset, Ab/IL-2 treatment was not sufficient to reverse hyperglycemia. However, it did promote survival in the absence of exogenous insulin. Proliferation of beta cells could not account for this improvement as few beta cells remained. Rather, abnormal insulin and glucagon dual-expressing cells were the only insulin-expressing cells observed in islets from mice with established disease. Thus, these data suggest that in diabetic NOD mice, beta cells have an innate capacity for regeneration both early and late in disease

  7. Low incidence of spontaneous type 1 diabetes in non-obese diabetic mice raised on gluten-free diets is associated with changes in the intestinal microbiome.

    Full Text Available Human and animal studies strongly suggest that dietary gluten could play a causal role in the etiopathogenesis of type 1 diabetes (T1D. However, the mechanisms have not been elucidated. Recent reports indicate that the intestinal microbiome has a major influence on the incidence of T1D. Since diet is known to shape the composition of the intestinal microbiome, we investigated using non-obese diabetic (NOD mice whether changes in the intestinal microbiome could be attributed to the pro- and anti-diabetogenic effects of gluten-containing and gluten-free diets, respectively. NOD mice were raised on gluten-containing chows (GCC or gluten-free chows (GFC. The incidence of diabetes was determined by monitoring blood glucose levels biweekly using a glucometer. Intestinal microbiome composition was analyzed by sequencing 16S rRNA amplicons derived from fecal samples. First of all, GCC-fed NOD mice had the expected high incidence of hyperglycemia whereas NOD mice fed with a GFC had significantly reduced incidence of hyperglycemia. Secondly, when the fecal microbiomes were compared, Bifidobacterium, Tannerella, and Barnesiella species were increased (p = 0.03, 0.02, and 0.02, respectively in the microbiome of GCC mice, where as Akkermansia species was increased (p = 0.02 in the intestinal microbiomes of NOD mice fed GFC. Thirdly, both of the gluten-free chows that were evaluated, either egg white based (EW-GFC or casein based (C-GFC, significantly reduced the incidence of hyperglycemia. Interestingly, the gut microbiome from EW-GFC mice was similar to C-GFC mice. Finally, adding back gluten to the gluten-free diet reversed its anti-diabetogenic effect, reduced Akkermansia species and increased Bifidobacterium, Tannerella, and Barnesiella suggesting that the presence of gluten is directly responsible for the pro-diabetogenic effects of diets and it determines the gut microflora. Our novel study thus suggests that dietary gluten could modulate the

    Full Text Available Abstract Background Patients with type 1 diabetes have a substantial risk of developing cardiovascular complications early in life. We aimed to explore the role of insulin sensitivity (Si as an early factor of atherosclerosis in young type 1 diabetes vs. non-diabetic subjects. Methods Forty adolescent and young adult individuals (20 type 1 diabetics and 20 non-diabetics, age 14–20 years, without characteristics of the metabolic syndrome, participated in this cross-sectional study. After an overnight fast, Si was measured by hyperinsulinemic euglycemic clamp (40 mU/m2 and calculated by glucose infusion rate (GIR. Carotid intima-media thickness (cIMT was measured in the common carotid artery with high-resolution ultrasonography. Risk factors of atherosclerosis (Body mass index [BMI], waist circumference, systolic blood pressure [sBP], triglycerides, low HDL-cholesterol and HbA1c were also investigated. Results cIMT was increased (0.52 ± 0.1 vs. 0.47 ± 0.1 mm, P vs. 7.1 ± 2.2 mg/kg/min, P vs. non-diabetics. The differences in cIMT were negatively associated with Si (r = −0.4, P r = 0.34, P = 0.03, with no such associations between BMI (r = 0.15, P = 0.32, sBP (r = 0.09, P = 0.58, triglycerides (r = 0.07, P = 0.66, HDL-cholesterol (r = 0.10, P = 0.55 and HbA1c (r = 0.24, P = 0.13. In a multivariate regression model, between cIMT (dependent and group (explanatory, only adjustment for Si affected the significance (ß = 0.08, P = 0.11 vs. (ß = 0.07, P i was observed. Conclusions cIMT is increased and associated with insulin resistance in adolescent, non-obese type 1 diabetic subjects. Although, no conclusions toward a causal relationship can be drawn from current findings, insulin resistance emerges as an important factor reflecting early signs of atherosclerosis in this small cohort.

    Obese patients are at increased risk for hypoventilation, leading to hypercapnea and acidosis. The primary objective of this study was to compare the incidence of perioperative hypercapnea in non-obese and morbidly obese patients using the SenTec transcutaneous PCO2 (tcPCO2) monitor. 10 morbidly obese subjects (BMI > 40 kg/m(2)) undergoing laparoscopic bariatric surgery, and 10 non-obese subjects (BMI < 30 kg/m(2)) undergoing laparoscopic abdominal procedures were studied, using a standardized anesthesia regimen. TcPCO2 and SpO2 were monitored continuously intraoperatively, and during the first 24 h postoperatively. Opiate consumption, respiratory rate (RR), and pain scores were collected from postanesthesia care unit (PACU) and ward nursing notes. RR, SpO2, and tcPCO2 did not differ significantly between groups during PACU or ward time periods. End-tidal CO2 (EtCO2) values were similar between groups during the intraoperative period, but tcPCO2 was significantly higher in the obese group at specific time points, and trended towards being higher throughout the case. Our study did not show significant tcPCO2 differences between non-obese and obese post-surgical patients, however, it did allow for continuous, trendable, nonobtrusive monitoring throughout the perioperative period. As V/Q mismatch increases with the PaCO2/EtCO2 gradient, and this effect is most pronounced in morbidly obese patients, tcPCO2 monitoring may prove to be a useful additional monitor in these patients during the intraoperative period.

    Full Text Available OBJECTIVE: The aim of this study was to determine (i the effect of maternal obesity and gestational diabetes mellitus (GDM on (i the circulating levels of omentin-1 in cord and maternal plasma, and (ii gene expression and release of omentin-1 from human placenta and adipose tissue. The effect of pregnancy on circulating omentin-1 levels was also determined. DESIGN: Omentin-1 levels were measured in maternal and cord plasma from obese and non-obese normal glucose tolerant women (NGT; n = 44 and women with GDM (n = 39 at the time of term elective Caesarean section. Placenta and adipose tissue expression and release of omentin-1 was measured from 22 NGT and 22 GDM women collected at the time of term elective Caesarean section. Omentin-1 levels were also measured in maternal plasma from 13 NGT women at 11 and 28 weeks gestation and 7 weeks postpartum. RESULTS: Maternal obesity was associated with significantly lower omentin-1 levels in maternal plasma; however, there was no effect of maternal obesity on cord omentin levels. Omentin-1 gene expression was lower in placenta and adipose tissue obtained from women with pre-existing obesity. In addition to this, adipose tissue release of omentin-1 was significantly lower from obese pregnant women. Omentin-1 levels were significantly lower in non-obese GDM compared to non-obese NGT women. However, there was no difference in omentin-1 levels between obese NGT and obese GDM women. There was no effect of GDM on cord omentin levels, and placental and adipose tissue omentin-1 expression. Maternal omentin-1 levels were negatively correlated with fetal birthweight and fetal ponderal index. CONCLUSIONS: The data presented in this study demonstrate that pre-existing maternal obesity is associated with lower omentin-1 expression in placenta, adipose tissue and maternal plasma. Alteration in omentin-1 in pregnancy may influence the development of metabolic disorders in offspring later in life.

    To investigate diagnostic accuracy of 3{sup rd}-generation dual-source CT (DSCT) coronary angiography in obese and non-obese patients. We retrospectively analyzed 76 patients who underwent coronary CT angiography (CCTA) and invasive coronary angiography. Prospectively ECG-triggered acquisition was performed with automated tube voltage selection (ATVS). Patients were dichotomized based on body mass index in groups A (<30 kg/m{sup 2}, n = 37) and B (≥30 kg/m{sup 2}, n = 39) and based on tube voltage in groups C (<120 kV, n = 46) and D (120 kV, n = 30). Coronary arteries were assessed for significant stenoses (≥50 % luminal narrowing) and diagnostic accuracy was calculated. Per-patient overall sensitivity, specificity, positive predictive value, negative predictive value (NPV) and accuracy were 96.9 %, 95.5 %, 93.9 %, 97.7 % and 96.1 %, respectively. Sensitivity and NPV were lower in groups B and D compared to groups A and C, but no statistically significant differences were observed (group A vs. B: sensitivity, 100.0 % vs. 93.3 %, p = 0.9493; NPV, 100 % vs. 95.5 %, p = 0.9812; group C vs. D: sensitivity, 100.0 % vs. 92.3 %, p = 0.8462; NPV, 100.0 % vs. 94.1 %, p = 0.8285). CCTA using 3{sup rd}-generation DSCT and (ATVS) provides high diagnostic accuracy in both non-obese and obese patients. (orig.)

    To compare perioperative and postoperative outcomes of laparoscopic hysterectomy (LH) in surgical management of gynecological conditions in two groups of different weight. A prospective comparative clinical study of 271 LH performed for disease of female pelvic organs in a group of 54 obese patients (over 30 body mass index (BMI)) and in a group of 217 non-obese patients (less than 30 BMI). The following criteria were assessed: patient characteristics, indications for surgery, previous surgery, presence of adhesions, duration of procedure, blood loss, weight of specimen, hospital stay and complications. Statistical analysis was performed using the unpaired t-test and non-parametric Chi-square test when appropriate, with a significance level of P=0.05. Three non-obese patients were converted to laparotomy due to operative complications. Laparoscopy in the remaining 268 patients (98.89%) was completed successfully. There was no significant difference in estimated blood loss, presence and degree of adhesions, weight of specimen, length of hospital stay and postoperative complications between women with high BMI and those with low BMI. The rate of major operative complications (5.55% versus 3.22%) was higher in the obese group. The duration of the operation was longer in obese women. However, the significance of the difference was borderline (P=0.06).

    Osteoporosis and sarcopenia are common health problems in postmenopausal women. However, studies of these issues in premenopausal women are limited. Our present study aimed to investigate relationship the between underweight, bone mineral density (BMD) and skeletal muscle index (SMI) in a representative sample of premenopausal Korean women. We used data from the Korea National Health and Nutrition Examination Surveys (2009-2010). Participants included 1767 healthy, ≥ 20-year-old, non-obese premenopausal women. Underweight was defined as BMIrelationship between underweight, BMD and SMI after adjusting for confounding factors. The prevalence of low BMD and low SMI in underweight women was 23.9% and 18.4%, respectively, compared with 9.4% and 1.7% in normal weight women. Low BMD and/or low SMI were present in 36.7% of underweight women compared with 10.7% of normal weight women. After adjustments, underweight women exhibited a higher odds ratio for low BMD (OR, 3.41; 95% CI, 2.31-5.05), low SMI (OR, 11.61; 95% CI, 6.17-21.88) and combined low BMD and low SMI (OR, 23.82; 95% CI, 8.92-63.58) when compared with normal weight women. Underweight premenopausal women are at a higher risk of low bone mass and low skeletal muscle. Educational efforts that promote a normal weight in premenopausal women should be reinforced. © 2016 John Wiley & Sons Ltd.

    Full Text Available Obesity is the common clinical signs in hirsutism, which can cause metabolic disturbances like dyslipidemia, insulin resistance and hypertension. To investigate relationship of overweight and obesity with hormonal and metabolic parameters in suspected hirsute women, in a cross-sectional study, 184 suspected hirsute women were selected in a reproductive endocrinology outpatient clinic in north of Tehran from February 1997 to May 1999. Weight, height, waist and hip circumferences were measured and serum levels of lipids, hormones and glucose were determined. Overweight and overall obesity (OO-body mass index: BMI ≥ 25 kg/m² and android obesity (AO-waist to hip ratio: WHR>0.85 were calculated. Hirsutism score of OO and AO women was higher than that of non-obese women (NO, P<0.001. OO woman had significantly lower levels of serum LH, estradiol, HDL and higher levels of triglyceride (TG, LDL and LDL/HDL ratio than non-obese women (P<0.05. In addition, the mean BMI, LH/FSH ratio and serum levels of testosterone (T, dehydroepiandrostenedione sulfate (DHEAS, insulin, and TG of AO women were higher (P<0.05 and their glucose/insulin ratio was lower than non-android obese women (NAO: WHR≤0.85; P<0.03. Multiple regression analysis of the data showed that WHR correlated most significantly with serum cholesterol, LDL and HDL levels; serum androstenedione with LDL/HDL ratio and serum glucose; and less significantly serum LH with serum insulin levels (P<0.02. Metabolic disturbances in these women are mostly due to obesity (especially android obesity, and high serum androstenedione levels.

    Unrealistic weight loss expectations (WLEs) and greater body dissatisfaction may be associated with the poor long-term outcomes of dietary and lifestyle weight loss treatments. We evaluated the association between body size, WLEs and body dissatisfaction in young women attempting to lose weight. Forty-four young healthy women [age range 18-35 years, body mass index (BMI) range 23-40 kg/m2] were recruited. Women were classified as obese (BMI ≥ 30.0 kg/m2) and non-obese (BMI social (career, family acceptance, peer acceptance, mass media, social pressure) factors. Individual WLEs were compared with recommended clinical targets (5%, 10% and 20%) for weight loss. Body dissatisfaction was lower in non-obese subjects and was directly associated with BMI (P media, whereas they perceived that family and friends were supportive of a lesser degree of weight loss. We observed a mismatch between clinical and personal expectations, and social pressure and interpersonal relationships appear to have a prominent role with respect to influencing the association. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

    Adipocytokines may alter normal metabolic function and play an important role in the pathophysiology of polycystic ovary syndrome (PCOS). We prospectively evaluated a cohort of obese and non-obese women with PCOS and non-PCOS controls for both novel (chemerin and omentin-1) and established (leptin and adiponectin) adipokines. Compared with age-matched controls, non-obese women with PCOS had decreased serum omentin-1 (191.1 ng/ml versus 269.7 ng/ml, p = 0.0001), while serum chemerin was not significantly altered in women with PCOS (53.95 ng/ml versus 48.61 ng/ml, p = 0.11). The findings were similar in the entire group of women with PCOS. However, in women with PCOS, chemerin correlated with leptin (r = 0.508, p = 0.004), adiponectin (r = -0.36, p = 0.014), and the leptin/adiponectin (L/A) ratio (r = 0.605, p women with PCOS, chemerin correlated with BMI (r = 0.317, p = 0.034), abdominal subcutaneous fat (r = 0.451, p = 0.0019), and insulin resistance (HOMA-IR, r = 0.428, p = 0.0034), while omentin-1 did not correlate with any parameter. These data suggest that chemerin although not significantly elevated in women with PCOS correlates with adiposity and insulin resistance, and it is the single best adipokine measured in this regard. Chemerin, through its inflammatory role as a chemo-attractant in adipose tissue, may be an important determinant of insulin resistance in PCOS.

    The role of white blood cell (WBC) count in pathogenesis of diabetes, cardiovascular disease, and obesity-related disorders has been reported earlier. Recent studies revealed that higher WBC contributes to atherosclerotic progression and impaired fasting glucose. However, it is unknown whether variations in WBC and haematologic profiles can occur in healthy obese individuals. The aim of this study is to further evaluate the influence of obesity on WBC count, inflammatory biomarkers, and metabolic risk factors in healthy women to establish a relationship among variables analyzed. The sample of the present study consisted of 84 healthy women with mean age of 35.56 +/- 6.83 years. They were categorized into two groups based on their body mass index (BMI): obese group with BMI > 30 kg/m2 and non-obese group with BMI count (PLT) with serum interleukin 6 (IL-6), C-reactive protein (CRP), angiotensin pi (Ang pi), body fat percentage (BF %), waist-circumference (WC), and lipid profile. WBC, PLT, CRP, and IL-6 in obese subjects were significantly higher than in non-obese subjects (p count in obese subjects was 6.4 +/- 0.3 (x10(9)/L) compared to 4.4 +/- 0.3 (x10(9)/L) in non-obese subjects (p = 0.035). WBC correlated with BF% (r = 0.31, p = 0.004), CRP (r = 0.25, P = 0.03), WC (r = 0.22, p = 0.04), angiotensin 11 (r = 0.24, p = 0.03), triglyceride (r = 0.24, p = 0.03), and atherogenic index of plasma (AIP) levels (r = 0.3, p = 0.028) but not with IL-6. Platelet count was also associated with WC and waist-to-hip ratio (p count and inflammatory parameters. There was also a positive relationship between WBC count and several inflammatory and metabolic risk factors in healthy women.

    To investigate whether selenium (Sel) treatment would impact on the onset of diabetes,we examined serum biochemical components including glucose and insulin,endoplasmic reticulum (ER) stress and insulin signalling proteins, hepatic C/EBP-homologous protein (CHOP) expression and DNA fragmentation in diabetic and non- diabetic conditions of non-obese diabetic (NOD) mice. We conclude that (i) Sel treatment induced insulin-like effects in lowering serum glucose level in Sel-treated NOD mice, (ii) Sel-treated mice had significantly decreased serum biochemical components associated with liver damage and lipid metabolism, (iii) Sel treatment led to the activation of the ER stress signal through the phosphorylation of JNK and eIF2 protein and insulin signal mechanisms through the phosphorylation of Akt and PI3 kinase, and (iv) Sel-treated mice were significantly relieved apoptosis of liver tissues indicated by DNA fragmentation assay in the diabetic NOD group. These results suggest that Sel compounds not only serve as insulin-like molecules for the downregulation of glucose level and the incidence of liver damage, but may also have the potential for the development of new drugs for the relief of diabetes by activating the ER stress and insulin signalling pathways.

    Full Text Available Abstract Background Type 2 diabetes mellitus (T2DM is a complex endocrine and metabolic disorder. Recently, several genome-wide association studies (GWAS have identified many novel susceptibility loci for T2DM, and indicated that there are common genetic causes contributing to the susceptibility to T2DM in multiple populations worldwide. In addition, clinical and epidemiological studies have indicated that obesity is a major risk factor for T2DM. However, the prevalence of obesity varies among the various ethnic groups. We aimed to determine the combined effects of these susceptibility loci and obesity/overweight for development of T2DM in the Japanese. Methods Single nucleotide polymorphisms (SNPs in or near 17 susceptibility loci for T2DM, identified through GWAS in Caucasian and Asian populations, were genotyped in 333 cases with T2DM and 417 control subjects. Results We confirmed that the cumulative number of risk alleles based on 17 susceptibility loci for T2DM was an important risk factor in the development of T2DM in Japanese population (P P P = 0.88 for trend. Conclusions Our findings indicate that there is an etiological heterogeneity of T2DM between obese/overweight and non-obese subjects.

    CD1d-restricted natural killer T (NKT) cells and CD4+CD25+regulatory T (Treg) cells are two thymus-derived subsets of regulatory T cells that play an important role in the maintenance of self-tolerance. Yet the functional changes of the two subsets of regulatory T cells in the development of diabetes in non-obese diabetic (NOD) mice remain unclear, and how NKT cells and CD4+CD25+ Treg cells cooperate functionally in the regulation of autoimmune diabetes is also uncertain.We provide evidence that in NOD mice, an animal model of human type 1 diabetes, the functions of both NKT cells and CD4+CD25+ Treg cells decrease in an age-dependent manner.We show that treatment with α-galactosylceramide increases the size of the CD4+CD25+ Treg cell compartment in NOD mice, and augments the expression of forkhead/winged helix transcription factor and the potency of CD4+CD25+ Treg cells to inhibit proliferation of CD4+CD25- T cells. Our data indicate that NKT cells and CD4+CD25+ Treg cells might cooperate in the prevention of autoimmune diabetes in NOD mice treated with α-galactosylceramide. Induced cooperation of NKT cells and CD4+CD25+ Treg cells could serve as a strategy to treat human autoimmune disease, such as type 1 diabetes.

    Immunodeficient non-obese diabetic (NOD)-severe combined immune-deficient (scid) mice bearing a targeted mutation in the gene encoding the interleukin (IL)-2 receptor gamma chain gene (IL2rγnull) engraft readily with human peripheral blood mononuclear cells (PBMC). Here, we report a robust model of xenogeneic graft-versus-host-like disease (GVHD) based on intravenous injection of human PBMC into 2 Gy conditioned NOD-scid IL2rγnull mice. These mice develop xenogeneic GVHD consistently (100%) following injection of as few as 5 × 106 PBMC, regardless of the PBMC donor used. As in human disease, the development of xenogeneic GVHD is highly dependent on expression of host major histocompatibility complex class I and class II molecules and is associated with severely depressed haematopoiesis. Interrupting the tumour necrosis factor-α signalling cascade with etanercept, a therapeutic drug in clinical trials for the treatment of human GVHD, delays the onset and progression of disease. This model now provides the opportunity to investigate in vivo mechanisms of xenogeneic GVHD as well as to assess the efficacy of therapeutic agents rapidly. PMID:19659776

    Immunodeficient mice bearing targeted mutations in the IL2rg gene and engrafted with human immune systems are effective tools for the study of human haematopoiesis, immunity, infectious disease and transplantation biology. The most robust human immune model is generated by implantation of human fetal thymic and liver tissues in irradiated recipients followed by intravenous injection of autologous fetal liver haematopoietic stem cells [often referred to as the BLT (bone marrow, liver, thymus) model]. To evaluate the non-obese diabetic (NOD)-scid IL2rγ(null) (NSG)-BLT model, we have assessed various engraftment parameters and how these parameters influence the longevity of NSG-BLT mice. We observed that irradiation and subrenal capsule implantation of thymus/liver fragments was optimal for generating human immune systems. However, after 4 months, a high number of NSG-BLT mice develop a fatal graft-versus-host disease (GVHD)-like syndrome, which correlates with the activation of human T cells and increased levels of human immunoglobulin (Ig). Onset of GVHD was not delayed in NSG mice lacking murine major histocompatibility complex (MHC) classes I or II and was not associated with a loss of human regulatory T cells or absence of intrathymic cells of mouse origin (mouse CD45(+) ). Our findings demonstrate that NSG-BLT mice develop robust human immune systems, but that the experimental window for these mice may be limited by the development of GVHD-like pathological changes.

    The murine immune system is not necessarily identical to it human counterpart, which has led to the construction of humanized mice. The current study analysed whether or not a human immune system contained within the non-obese diabetic (NOD)-Rag1(null) -γ chain(null) (NRG) mouse model was an accurate representation of the original stem cell donor and if multiple mice constructed from the same donor were similar to one another. To that end, lightly irradiated NRG mice were injected intrahepatically on day 1 of life with purified cord blood-derived CD34(+) stem and progenitor cells. Multiple mice were constructed from each cord blood donor. Mice were analysed quarterly for changes in the immune system, and followed for periods up to 12 months post-transplant. Mice from the same donor were compared directly with each other as well as with the original donor. Analyses were performed for immune reconstitution, including flow cytometry, T cell receptor (TCR) and B cell receptor (BCR) spectratyping. It was observed that NRG mice could be 'humanized' long-term using cord blood stem cells, and that animals constructed from the same cord blood donor were nearly identical to one another, but quite different from the original stem cell donor immune system.

    Full Text Available Background: Polycystic ovary syndrome (PCOS is common diagnosis in women presenting with infertility. All the dimensions of PCOS have not been completely explored. Many studies have tried to characterize the exact presentation of the disease. In this study we studied clinical features of PCOS in Indian women to characterize different phenotypes of this syndrome. Prevalence of acanthosis nigricans (AN as surrogate marker of insulin resistance, obesity, hirsutism and hypothyroidism in PCOS women have been simultaneously studied. Materials and Methods: Present work is a non comparative cross-sectional open label study carried out over a period of 18 months in an endocrinology hospital in western Maharashtra, India. Results and Conclusion: Authors conclude that PCOS occurs both in obese and non-obese women; AN and hirsutism occur in equal proportion of patients. AN is correlated with obesity. Hormonal dysfunctions in PCOS manifested together or independently. PCOS women can be sub grouped based on clinical features suggestive of endocrinological malfunctions and can be investigated accordingly for selection of appropriate treatment modalities.

Methods: We interviewed 1.050 women aged 20-45 in the area of Campinas, Brazil, to investigate the prevalence of overactive bladder symptoms. In this study, we used the ICIQ-OAB questionnaire (ICS standard, in its validated portuguese version and a specific questionnaire for the demographics, which includes information about BMI. Results: Overall, women with BMI ≥30 presented a significantly higher score than women with a lower BMI (18.5 - 24.9 (p=0.0066. In the analysis of individual symptoms, no significant differences were found regarding urinary frequency (p=0.5469. Women with BMI ≥30 presented more nocturia than women with BMI ranging between 18.5 and 24.9 (p=0.0154. Women in the group of BMI 25 - 29.9 presented more urgency than women with BMI 18.5 - 24.9 (p=0.0278. Significant difference was also found regarding urge-incontinence; women with BMI 25 - 29.9 presented a higher score than women in the group 18.5 - 24.9 (p= 0.0017. Analysis was also performed on the visual analogue scale regarding how much each symptom bothers the women (quality of life. There were no significant differences regarding frequency, nocturia or urgency but urgency incontinence bother was significant. Women with BMI 25 - 29.9 were more bothered by incontinence than women with BMI 18.5 - 24.9 (p=0.002. Conclusion: In conclusion, this study reinforces the correlation between BMI and OAB symptoms. Obese women present more OAB symptoms than non-obese women.

    Total laparoscopic hysterectomy (TLH) in obese patients is challenging. We sought to evaluate whether total laparoscopic hysterectomies using the da Vinci robotic system in obese patients, in comparison with non-obese patients, is a reasonable surgical approach. One-hundred consecutive robot-assisted TLHs were performed over a 17-month period. Obesity was not a contraindication to robotic surgery, assuming adequate respiratory function to tolerate Trendelenburg position and, for cancer cases, a small enough uterus to allow vaginal extraction without morcellation. Data were prospectively collected on patient characteristics, total operative time, hysterectomy time, estimated blood loss, length of stay, and complications. Outcomes with non-obese and obese women were compared. The median age, weight, and BMI of the 100 patients who underwent robot-assisted TLH was 57.6 years (30.0-90.6), 82.1 kg (51.9-159.6), and 30.2 kg/m(2) (19.3-60.2), respectively. Fifty (50%) patients were obese (BMI ≥ 30); 22 patients were morbidly obese (BMI ≥ 40). There was no increase in complications (p = 0.56) or blood loss (p = 0.44) with increasing BMI. While increased BMI was associated with longer operative times (p = 0.05), median time increased by only 36 min when comparing non-obese and morbidly obese patients. Median length of stay was one day for all weight categories (p = 0.42). Robot-assisted TLH is feasible and can be safely performed in obese patients. More data are needed to compare robot-assisted TLH with other hysterectomy techniques in obese patients. Nonetheless, our results are encouraging. Robot-assisted total laparoscopic hysterectomy may be the preferred technique for appropriately selected obese patients.

    We sought to determine whether Litomosoides sigmodontis, a filarial infection of rodents, protects against type 1 diabetes in non-obese diabetic (NOD) mice. Six-week-old NOD mice were sham-infected or infected with either L3 larvae, adult male worms, or adult female worms. Whereas 82% of uninfected NOD mice developed diabetes by 25 weeks of age, no L. sigmodontis-infected mice developed disease. Although all mice had evidence of ongoing islet cell inflammation by histology, L. sigmodontis-infected mice had greater numbers of total islets and non-infiltrated islets than control mice. Protection against diabetes was associated with a T helper type 2 (Th2) shift, as interleukin-4 (IL-4) and IL-5 release from alpha-CD3/alpha-CD28-stimulated splenocytes was greater in L. sigmodontis-infected mice than in uninfected mice. Increased circulating levels of insulin-specific immunoglobulin G1, showed that this Th2 shift occurs in response to one of the main autoantigens in diabetes. Multicolour flow cytometry studies demonstrated that protection against diabetes in L. sigmodontis-infected NOD mice was associated with significantly increased numbers of splenic CD4(+) CD25(+) FoxP3(+) regulatory T cells. Interestingly, injection of crude worm antigen into NOD mice also resulted in protection against type 1 diabetes, though to a lesser degree than infection with live L. sigmodontis worms. In conclusion, these studies demonstrate that filarial worms can protect against the onset of type 1 diabetes in NOD mice. This protection is associated with a Th2 shift, as demonstrated by cytokine and antibody production, and with an increase in CD4(+) CD25(+) FoxP3(+) regulatory T cells.

    The present investigations were aimed to identify the possible association between genetic polymorphism in interleukin-6 (IL-6) G-174C gene, which confers susceptibility to metabolic syndrome, and serum level of resistin in North Indian women. The study population comprised 370 unrelated Indian women (192 having abdominal obesity and 178 controls). Polymorphism in genotype (CC+GC) of IL-6 G-174C gene was determined using a combination of polymerase chain reaction (PCR) and sequence-specific primer with restriction fragment length polymorphism (RFLP) technology. Insulin resistance (IR) and serum resistin level were also analyzed along with metabolic risk factors. Of 192 abdominal obese women, 147 (76.56%) were found to have mutant CC+GC (p = 0.001) genotype and allele frequency (p = 0.001), which was significantly higher 45 (23.44%) than non-obese and their respective wild type. The mutant genotype (CC+GC) of IL-6 gene was found to be associated significantly with high triglyceride (p = 0.025) and resistin level (p obese women. Non-obese women with no signs of metabolic risk factors were found to have significantly low level of serum resistin and IR in comparison to obese women having genetic polymorphism for IL-6 G-174C gene. Study suggests that IL-6 G-174C gene is one among the susceptibility loci for metabolic syndrome in North Indian women. Genotype for this polymorphism may prove informative for prediction of genetic risk for metabolic syndrome. Further, high level of serum resistin molecules may be targeted to correlate with metabolic syndrome risk factors and could be used as early prediction marker.

    Full Text Available Abstract Background Cultural norms indicate that obesity reflects increased wealth and prosperity. Yet obesity is linked to serious medical illnesses. The purpose of this study was to determine if Ghanaian women would change their body image if it meant a healthier life. Methods A questionnaire was administered to 305 Ghanaian women waiting for clinic appointments at Korle Bu Teaching Hospital, Accra Ghana. This survey included questions on current health, selection of figural stimuli, decision making on health and social determinants and 5 questions on self-perception of health from SF-36. Anthropometric measures were taken and body mass index calculated. Women were also provided with health related information at the conclusion of the interview. Results The majority of all women surveyed would reduce their current body image if it meant that they would have an overall healthier life and reduce the risks of obesity-linked illnesses and complications. Currently obese women were significantly more likely than non-obese women to reduce their body image to reduce the risk of hypertension (OR 2.03 [1.64 – 2.51], Conclusion The Ghanaian women interviewed in this study are interested in living a healthy life and are willing to reduce their body size to reduce the risk of obesity-linked illnesses. The target group for any interventional studies and measures to reduce obesity appears to be women age 50 and younger.

    Full Text Available OBJECTIVE: To describe the reported energy and nutrient intake and adequacies in Mexican women. MATERIAL AND METHODS: A 24-hour dietary recall was used to obtain nutrient intake in a representative sub-sample of 2 630 women from 12 to 49 years of age from the National Nutrition Survey 1999. Nutrient adequacies were estimated using the Dietary Reference Intakes and stratified according to region, area (urban or rural, socioeconomic status and obesity status (non-obese: BMI 30 kg/m². Differences were analyzed using linear regression for complex surveys of log-transformed intake and adequacy, adjusting for multiple comparisons with the Bonferroni test. RESULTS: The median national energy intake was 1 471 kcal. The Risk of Inadequacy (RI (prevalence of adequacy <50% was: vitamin A:38.3%, vitamin C: 45.5%, and folate: 34.3%. Carbohydrates, folate, iron and calcium intake was significantly higher in rural than in urban areas. The RI was higher in women of the lowest socioeconomic status tertile for all nutrients with the exception of carbohydrates and calcium. Macro-nutrient adequacies were significantly higher in non-obese women. CONCLUSIONS: Differences within the country among regions, rural and urban areas, and socioeconomic status tertile reflect an increasing availability of inexpensive calorie-dense foods in marginal groups. However, total energy, cholesterol, saturated and total fat were consumed in greater quantities by women from the higher socioeconomic status tertile and from urban areas. These patterns could be a contributing factor to the rise of obesity and other non-communicable nutrition-related chronic diseases in Mexico.

    While the association between obesity and urinary incontinence (UI) in women has been clearly documented, the relationship with anal incontinence (AI) is less well defined; moreover, while bariatric surgery has been shown to improve UI, its effect on AI is still unclear. A total of 32 obese women were studied by means of PFDI-20 and PFIQ-7 questionnaires and anorectal manometry before and after bariatric surgery and compared with 71 non-obese women. Obese women showed worse overall questionnaire results (OR 5.18 for PFDI-20 and 2.66 for PFIQ-7). Whereas obese women showed worse results for urinary sub-items and a higher urge UI incidence (43.8 vs 18.3 %, p = 0.013), they did not show worsening in colorecto-anal symptoms. Post-operatively, median PFDI-20 total score did not change (24.2 vs 26.6, p = ns), while there was an improvement in urinary score (14.6 vs 8.3, p flatus incontinence increased from 18.8 to 37.5 % (p = ns). Anorectal manometry did not show significant changes after surgery. Obese women had worse questionnaire results, but while showing a higher incidence of UI, they did not experience anorectal function worsening. After bariatric surgery, there was a slight improvement in PFD symptoms related to UI, but anorectal function did not change significantly and flatus incontinence increased.

    Objective To examine the change of white blood cell level in obese and non-obese patients with coronary heart disease (CHD) and its clinical significance. Methods Two hundred and thirty patients with CHD were divided into two groups: obesity with CHD [n = 115, body mass index (BMI) ^28 kg/m2 or waist-to-hip ratio (WHR)>0.9 (male) or 0.85>(female)], and non-obesity with CHD (n = 115). Another 130 subjects served as the control group. The degree of coronary stenosis was quantitatively assessed according to the fractional imaging of coronary artery evaluation standard (American Heart Association, 1984) and Gensini scoring system. The changes of the total white blood cell count and white blood cell classification were compared between obese and non-obese patients with CHD. The correlation of the total white blood cell count with obesity index and blood biochemical parameters was analyzed by correlation analysis and multivariate stepwise regression analysis. Results The total white blood cell count of obesity CHD group was significantly higher than that of non-obesity CHD group and control group [(7.83±2.93), (7.00±1.83) and (6. 36±1. 72) (lO'/L, respectively;all P<0.05). The levels of low-density lipoprotein (LDL-C), apolipoprotein-B (ApoB) and Gensini score were also significantly higher in obesity group than in non-obesity group (all P<0. 05). The level of apolipoprotein-A (ApoA) was significantly lower in obesity group than in control group (P<0.05), but obesity group and non-obesity group did not differ significantly in ApoA (P>0.05). In obesity group, the total white blood cell count was positively correlated with ApoB while in non-obesity group the total white blood cell count was negatively correlated with ApoA. Conclusion The count of total white blood cells of obesity patients with coronary heart disease is higher than that of non-obesity coronary heart disease patients. ApoB and ApoA are the major factors affecting total white blood cells in

To study the role of the trace elements in diabetes and obesity, serum trace elements levels (Cr, Se, Fe, Zn, Cu and Mn were measured in obese women with or without diabetes as well as healthy women. Further, correlation between serum trace elements levels and glucose, insulin, homeostasis model assessment (HOMA-IR, glycated haemoglobin (HbA 1 c, body mass index (BMI, waist circumferences, waist -to -hip ratio and high-sensitivity C-reactive protein(hsCRP were also determined in these women. Methods: This study was performed with morbidly obese (BMI >40 kg/m 2 women with diabetes (n=41, without diabetes (n=45 and 50 healthly non obese women. Anthropometric measurements were taken and levels of serum Zn, Cr, Fe Cu and Mn were determined. Biochemical parameters included serum glucose, insulin, lipids, haemoglobin, hsCRP and HbA1C. Results: The levels of Zn (P<0.001, Mn (P<0.05, Fe (P<0.05 were significantly lower and the level of Cu (P<0.001 and Cu / Zn ratio (P<0.05 were significantly higher in the diabetic obese women than those of the healthy women. Also, the levels of Zn and Fe were significantly lower and the levels of Cu were significantly higher in the non diabetic obese women than those of the healthy group. Serum Zn levels negatively and serum Cu levels positively correlated with anthropometric values in diabetic and non diabetic obese women. Further, serum Zn, Mn and Cr levels negatively correlated and serum Se levels positively correlated glycaemia control parameters in diabetic obese women. In addition, serum Zn levels negatively correlated with hsCRP in diabetic and nondiabetic obese females. Interpretation & conclusions: Our findings showed significant association between Zn and Fe deficiencies and obesity. Also, obese women with diabetes may be at a

    The Summer Electronic Benefit Transfers for Children (SEBTC) demonstration piloted summer food assistance through electronic benefit transfers (EBTs), providing benefits either through the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) or the Supplemental Nutrition Assistance Program (SNAP) EBT. To inform food assistance policy and describe how demonstrations using WIC and SNAP models differed in benefit take-up and impacts on food security and children's food consumption. Sites chose to deliver SEBTC using the SNAP or WIC EBT system. Within each site, in 2012, households were randomly assigned to a benefit group or a no-benefit control group. Grantees (eight states and two Indian Tribal Organizations) selected school districts serving many low-income children. Schoolchildren were eligible in cases where they had been certified for free or reduced-price meals during the school year. Before the demonstration, households in the demonstration sample had lower incomes and lower food security, on average, than households with eligible children nationally. Grantees provided selected households with benefits worth $60 per child per summer month using SNAP or WIC EBT systems. SNAP-model benefits covered most foods. WIC-model benefits could only be used for a specific package of foods. Key outcomes were children's food security (assessed using the US Department of Agriculture food security scale) and food consumption (assessed using food frequency questions). Differences in mean outcomes between the benefit and control groups measured impact, after adjusting for household characteristics. In WIC sites, benefit-group households redeemed a lower percentage of SEBTC benefits than in SNAP sites. Nonetheless, the benefit groups in both sets of sites had similar large reductions in very low food security among children, relative to no-benefit controls. Children receiving benefits consumed more healthful foods, and these impacts were larger in WIC

    The effect of body mass index (BMI) and obesity on apo A-I levels and kinetics was examined by gender. ApoA-I kinetics were determined with a primed-constant infusion of deuterated leucine in the fed state in 19 men and 13 postmenopausal women. Compared to nonobese men, nonobese women had a higher HDL-C and apoA-I level due to a 48% higher apoA-I PR (p=0.05). Obesity had no significant effects on apoA-I kinetics in women. In contrast, compared to non-obese men, obese men had a 9% lower apoA-I level due to a 64% higher FCR partially offset by a 47% higher PR. Obese women had a 52% higher HDL-C than obese men (50 mg/dL vs 33 mg/dL, respectively, p=0.012), a finding related to the faster apoA-I FCR in obese men. BMI was directly correlated with apoA-1 FCR (r = 0.84, p < 0.001) and PR (r = 0.79, p < 0.001) in men but not women. 62% of the variability in PR and 71% of the variability in FCR were due to BMI in men and only 3% and 23%, respectively, in women. In conclusion, BMI has a significant effect on apoA-I PR and FCR in men but not in women. PMID:17570251

    Impaired glucose metabolism-related genetic variants and traits likely interact with obesity and related lifestyle factors, influencing postmenopausal breast and colorectal cancer (CRC), but their interconnected pathways are not fully understood. By stratifying via obesity and lifestyles, we partitioned the total effect of glucose metabolism genetic variants on cancer risk into two putative mechanisms: 1) indirect (risk-associated glucose metabolism genetic variants mediated by glucose metabolism traits) and 2) direct (risk-associated glucose metabolism genetic variants through pathways other than glucose metabolism traits) effects. Using 16 single-nucleotide polymorphisms (SNPs) associated with glucose metabolism and data from 5379 postmenopausal women in the Women's Health Initiative Harmonized and Imputed Genome-Wide Association Studies, we retrospectively assessed the indirect and direct effects of glucose metabolism-traits (fasting glucose, insulin, and homeostatic model assessment-insulin resistance [HOMA-IR]) using two quantitative tests. Several SNPs were associated with breast cancer and CRC risk, and these SNP-cancer associations differed between non-obese and obese women. In both strata, the direct effect of cancer risk associated with the SNP accounted for the majority of the total effect for most SNPs, with roughly 10% of cancer risk due to the SNP that was from an indirect effect mediated by glucose metabolism traits. No apparent differences in the indirect (glucose metabolism-mediated) effects were seen between non-obese and obese women. It is notable that among obese women, 50% of cancer risk was mediated via glucose metabolism trait, owing to two SNPs: in breast cancer, in relation to GCKR through glucose, and in CRC, in relation to DGKB/TMEM195 through HOMA-IR. Our findings suggest that glucose metabolism genetic variants interact with obesity, resulting in altered cancer risk through pathways other than those mediated by glucose metabolism traits.

    Objective To compare the relationship between secretory characteristics of serum ghrelin and mechanism of metabolic syndrome in obese and non-obese patients with polycystic ovarian syndrome (PCOS). Methods Based on the body mass index (BMI), 60 PCOS patients were divided into two groups, 30 cases in obese group ( BMI ≥ 25 kg/m2)and 30 cases in non-obese group (BMI < 25 kg/m2). Thirty infertile patients with tubal factor and normal menstruation were the control group. The serum levels of ovarian sex steroid hormones were detected by fully automatic chemiluminescence method, and the experiment of sugar metabolism was carried out in three groups. The serum ghrelin level was detected by enzyme linked immunosorbent assay (ELISA). The correlation between ghrelin level and biochemical metabolic indexes was analyzed by simple correlation analysis. Results (1) The serum ghrelin level was significantly lower in obese group (1.84±0.46) and non-obese group (2.13±0.52) than that of control group (2.52±0.78, P< 0.05), and the level was significantly lower in obese group than that of non-obese group. (2) The values of fasting insulin (FIN), homeostasis model assessment insulin resistance index (HOMA-IR), and serum INS levels of 2 h and 3 h oral glucose tolerance test (OGTT) were significantly higher in obese group than those of non-obese group and control group (P < 0.05). In non-obese group, the serum values of LH and LH/FSH were markedly higher than those of obese group and control group. (3) The serum ghrelin level was negatively correlated with FIN and HOMA-IR (r=-0.542 and -0.503, P < 0.05). In non-obese group, the serum ghrelin level was negatively correlated with testosterone (r=-0.568, P<0.05). Conclusion The serum ghrelin levels may play a significant role in pathogenesis mechanisms in PCOS patients especially in obese ones.%目的 比较肥胖与非肥胖型多囊卵巢综合征(PCOS)患者血清胃促生长素(Ghrelin)分泌特点及其与代

    Full Text Available Since high bone turnover is associated with decreased bone mass, biochemical markers of bone remodeling, such as serum osteocalcin, may be used to assess osteoporosis and to predict fractures in elderly women, particulary those involving trabecular bone, and use of a combination of bone mineral density (BMD and biochemical markers may improve fracture prediction. The serum levels of osteocalcin constitute a specific biochemical parameter of bone formation. Compared to imaging techniques, assays for osteocalcin are safe, noninvasive and easily performed. The aim of this study was to determine the relationship of serum osteocalcin and BMD in postmenopausal women. A cross sectional study was performed on 53 postmenopausal women in South Jakarta from February to April 2010. The subjects were assessed for anthropometric characteristics, serum osteocalcin levels and BMD. BMD was measured at the lumbar spine, right femoral neck and at the left distal radius by dual energy X-ray absorptiometry (DXA. Mean serum osteocalcin was 28.99 ± 10.02 ng/ml. The Pearson correlation test on all subjects indicated a significant inverse correlation between serum osteocalcin and femoral neck BMD (r = - 0.29; p=0.034. By arranging the data into tertiles, a significant association was found in non-obese subjects between mean femoral neck BMD and serum osteocalcin (p=0.036. The Tukey posthoc multiple comparison test showed a significant mean difference in femoral neck BMD between the lowest and the highest tertiles of osteocalcin serum concentrations (p=0.028. Maintenance of body weight is important for maintaining BMD in postmenopausal women.

    Objective To investigate the-3826A/G polymorphism in the promoter of the uncoupling protein-1(UCP1) gene and its relations to obesity in Chinese population. Methods Three hundred and eighty-four subjects (257 non-obese and 127 obese individuals) from a population of Chinese Han nationality in Chengdu area were studied using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLPs). Serum lipids were measured by enzymatic kits and apolipoproteins AⅠ, AⅡ, B100, CⅡ,CⅢ and E were measured by the RID kits. Results The frequencies of A and G alleles at-3826A/G site in obese and non-obese groups were 0.508 and 0. 492, and 0. 467 and 0. 533, respectively. It showed no significant difference in allele frequencies between non-obese and obese groups (P>0.05). In the obese group, subjects with genotype GG had higher serum apo B100 concentrations, and those with genotype AG had higher apo CⅡ and apo CⅢ levels, than those with genotype AA, respectively (P0.05).-3826 A/G位点在肥胖组GG基因型携带者血清载脂蛋白(apolipoprotein,apo)B100水平高于AA基因型者(P<0.05),AG型者apo CⅡ、apo CⅢ水平均分别高于AA基因型携带者(P<0.05).在非肥胖男性亚组,GG纯合基因型携带者血清高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)及apoAⅠ水平显著低于AA基因型携带者(P<0.05);AG型者apoAⅡ水平低于AA基因型者.在肥胖男性亚组,GG基因型携带者血清apo B100水平较AA型者显著升高(P<0.05);在肥胖女性亚组,GG基因型者apo AⅠ水平低于AG型者,AG型者apoCⅡ、apoCⅢ水平均分别高于AA型者(P<0.05).结论 UCP1基因-3826A/G多态性与成都地区中国汉族人肥胖无关联,但与血清HDL-C及apoAⅠ、apoB100等载脂蛋白水平含量有关,且具有性别差异.

  8. Women and the media in Malaysia.

    1987-01-01

    The contributions of and portrayal of women in the Malaysian media are summarized here in detail. Women's access to training in journalism and education is on average better than that of men. There are 3 communications departments in institutions of higher learning in Malaysia, and all enroll more women than men, probably because of women's better language skills and desire to enter a "glamourous" profession. Women's participation in journalism, except for women's magazines, is much more limited, especially at higher levels. Women's abilities are not lacking, as shown by the number of awards Malaysian women journalists have won, but it is felt that women are not assertive, cannot work late or night shifts, cannot be transferred, because of family and domestic obligations. Perhaps journalism curricula should offer women extra courses in effective family management, public speaking or human relations, or assign cadet journalists women mentors. In Malaysia women are generally portrayed in print, electronic and advertising media as either decorative, foolish, consumption driven, or sex objects. Exploitative poses predominate in ads for male markets, such as automobiles and liquor. Sexual roles for women and girls are depicted as those of subservient or silly housewife or in other negative or traditional roles.

    High body mass index (BMI) and large waist circumference are separately associated with increased coronary heart disease (CHD) risk but these measures are highly correlated. Their separate associations with incident CHD, cross-classifying one variable by the other, are less investigated in large-scale studies. We examined these associations in a large UK cohort (the Million Women Study), which is a prospective population-based study. We followed 496,225 women (mean age 60 years) with both waist circumference and BMI measurements who had no vascular disease or cancer. Adjusted relative risk and 20-year cumulative CHD incidence (first coronary hospitalization or death) from age 55 to 74 years were calculated using Cox regression. Plasma apolipoproteins were assayed in 6295 randomly selected participants. There were 10,998 incident coronary events after mean follow up of 5.1 years. Within each BMI category (waist circumference; within each waist circumference category (waist circumference waist circumference ≥80 cm, with 1 in 8 (95% confidence interval 1 in 7 to 9) women developing CHD over the same period. Similar associations for apolipoprotein B to A1 ratio across adiposity categories were observed, particularly in non-obese women. Our conclusions were that both waist circumference and BMI are independently associated with incident CHD.

    In the fields of power conversion devices and broadcasting/communication amplifiers, high power, high frequency and low losses are desirable. Further, for electronic elements in aerospace/aeronautical/geothermal surveys, etc., heat resistance to 500degC is required. Devices which respond to such hard specifications are called hard electronic devices. However, with Si which is at the core of the present electronics, the specifications cannot fully be fulfilled because of the restrictions arising from physical values. Accordingly, taking up new device materials/structures necessary to construct hard electronics, technologies to develop these to a level of IC were examined and studied. They are a technology to make devices/IC of new semiconductors such as SiC, diamond, etc. which can handle higher temperature, higher power and higher frequency than Si and also is possible of reducing losses, a technology to make devices of hard semiconducter materials such as a vacuum microelectronics technology using ultra-micro/high-luminance electronic emitter using negative electron affinity which diamond, etc. have, a technology to make devices of oxides which have various electric properties, etc. 321 refs., 194 figs., 8 tabs.

    Hard material technologies were surveyed to establish the hard electronic technology which offers superior characteristics under hard operational or environmental conditions as compared with conventional Si devices. The following technologies were separately surveyed: (1) The device and integration technologies of wide gap hard semiconductors such as SiC, diamond and nitride, (2) The technology of hard semiconductor devices for vacuum micro- electronics technology, and (3) The technology of hard new material devices for oxides. The formation technology of oxide thin films made remarkable progress after discovery of oxide superconductor materials, resulting in development of an atomic layer growth method and mist deposition method. This leading research is expected to solve such issues difficult to be easily realized by current Si technology as high-power, high-frequency and low-loss devices in power electronics, high temperature-proof and radiation-proof devices in ultimate electronics, and high-speed and dense- integrated devices in information electronics. 432 refs., 136 figs., 15 tabs.

    1995-02-01

    The civil war in the former Yugoslavia has taken a toll on the women's movement which has disintegrated across male-defined nationalist borders. The women's movement in this area got its start during the Second World War but was disbanded under communism until women's groups began to form in the 1970s. Today the women's movement has lost the power to oppose the war and has been unable to prevent widespread violence perpetuated against women. Some feminists who have refused to embrace nationalism and patriotism have been vilified and have had to seek refuge abroad. Recently, however, hundreds of nongovernmental organizations have been formed to provide support to women and children victimized by the war. Women have been raped and impregnated as a strategy of male warfare, and raped women who refused an abortion were ostracized. War-related rape has yet to be fully recognized as an international human rights violation, and the issue is being used as political propaganda in the former Yugoslavia while it is ignored elsewhere. Sensationalist reporting of these rapes has further victimized women and made them unable to give voice to their trauma. War also increases women's suffering by destroying economic and social welfare systems. Oxfam is helping women record their testimonies of war and reconstruct the fabric of their societies through programs which provide income-generation and training in micro-enterprises. In addition, Oxfam is strengthening electronic communication and networking among women's groups throughout the region.

    Jill Conway is a feminist historian, writer, teacher, and now-emerita 1st woman president of Smith College. She claims that women today still suffer from a great deal of oppression. Women around the world are currently in a disadvantage position. In 7 countries women do not have the right to vote. In the US less that .5% of top executives are women. The wage gap in the US between 1939 and 1989 has only shrunk $.10, from $.58-$.68. Conway points out that we are all constrained by our social mores, generational attitudes, political events, and economic circumstances. Few people are able to overcome these things in the way that they live their lives. Conway questions the validity of history written from a male dominated point of view. Around the world the value of women's work is almost always lower than that of men. India is just 1 example, there 75% of women are illiterate and 1/2 the population lives in poverty based on a caste system. Female literacy tripled in the 1st 30 years of independence and by 1981 it had reached 25%. The literacy gap is actually growing in India Today with 44% of girls aged 6 to 11, who are eligible to attend school, not doing so. Rural poverty keeps them at home because their domestic work is more valuable than their education. Other cultural tradition compound the problem: arranged marriages often result in motherhood for 14 year old girls. This is done for many reasons, 1 of which is crop failure insurance. When 2 families are combined through marriage, their total land share grows and they are thus more likely to have enough to eat. Education is just 1 necessary step. Developed nations must realize the realities that exist in the countries they provide aid for. In Africa for example, 70% of continent's food is produced by women. Yet the aid programs of the past have only been designed to offer assistant to men and create jobs for men.

    Our objective was to evaluate changes in serum leptin levels during pregnancy in overweight/obese and non-obese women and to assess total and percent weight gain during pregnancy as possible factors that influence leptin levels. In a prospective study of 42 low-risk pregnant women receiving prenatal care, we assessed serum leptin levels at gestational weeks 9-12, 25-28, and 34-37. Based on their pre-pregnancy body mass indices (BMIs), the cohort was divided into: non-overweight (BMI pregnant women had a noticeably larger total weight gain. When analyzing the percent weight gain during pregnancy compared to the pre-pregnancy weight, the non-overweight group had a significantly greater percent weight gain than the overweight/obese group. Our results suggest that the greater increase in leptin levels in non-overweight pregnant women can be explained by the higher percent weight gain in this group compared to overweight/obese women. These findings suggest that controlling the percent weight gain may be an important preventive measure when controlling leptin levels during pregnancy and subsequent medical complications.

    Ambient air pollution is controllable, and it is one of the greatest environmental threats to human health. Studies conducted worldwide have provided evidence that maternal exposure to ambient air pollution during pregnancy enhances the risk of low birth weight at term (TLBW, air pollution. The aim of this commentary is to review the published literature on the association between ambient air pollution and TLBW regarding increased vulnerability for the above-mentioned subgroups. Although more than fifty epidemiological studies have examined the associations between ambient air pollution and TLBW to date, we only identified six studies that examined the potential effect modification of the association between ambient air pollution and TLBW by the above listed maternal risk factors. Two studies assessed effect modification caused by smoking on the association between ambient air pollution and TLBW. The adjusted odds ratio (OR) for TLBW associated with exposure to ambient air pollution were in one study higher among women who smoked during pregnancy, as compared to the OR of non-smoking women, while in the other study the association was in the opposite direction. The association of ambient air pollution and TLBW were higher among women characterized by extreme BMI (two studies) and low SES compared to non-obese women or women of higher SES (four studies), respectively. Only one study reported the estimated effects among asthmatic and non-asthmatic women and no statistically significant effect modification was evident for the risk of TLBW associated with ambient air pollution. The current epidemiologic evidence is scarce, but suggests that pregnant women who are smoking, being underweight, overweight/obese or having lower SES are a vulnerable subpopulation when exposed to ambient air pollution, with and increased risk of having a child with TLBW. The limited evidence precludes for definitive conclusions and further studies are recommended. Copyright © 2017. Published

    Body weight control is tightly regulated in the hypothalamus. The inaccessibility of human brain tissue can be partially solved by using cerebrospinal fluid (CSF) as a tool for assessing the central nervous system's production of orexigen and anorexigen factors. Using proteomic analysis, the present study investigated the differentially displayed proteins in human CSF from obese and non-obese subjects. We designed a case-control study conducted in a reference hospital where eight obese (cases) and eight non-obese (controls) women with idiopathic intracranial hypertension were included. Intracranial hypertension was normalised through the placement of a ventriculo- or lumboperitoneal shunt in the 12 months before their inclusion in the study. Isotope-coded protein label (for proteins > 10 kDa) and label-free liquid chromatography (for proteins obesity. Further studies aiming to investigating the precise role of these proteins in the pathogenesis of obesity and their potential therapeutic implications are needed. © 2012 The Authors.

    Obstructive sleep apnea (OSA) is associated with dyslipidemia. However, no study has focused on dyslipidemia in women with OSA. The aim of this study was to determine the prevalence and risk factors for dyslipidemia in women with OSA. Between 2007 and 2013, 570 eligible female patients with suspected OSA were consecutively recruited. The analyzed data consisted of polysomnography parameters, biochemical indicators, and anthropometric measurements. Serum lipid levels and dyslipidemia were compared. Binary logistic regression and multivariate linear regression models were used to determine the independent risk factors influencing serum lipids. After multivariate adjustment, there were essentially no major differences in serum lipid levels among patients with no to mild, moderate, and severe OSA nor did serum lipid levels change with OSA severity. Dyslipidemia in total cholesterol, triglycerides, low-density lipoprotein cholesterol, apolipoproteins(apo) B and apoE increased with OSA severity, but only in non-obese subjects and those <55 years of age. Age, body mass index, waist to hip ratio, glucose and insulin were major risk factors for most serum lipids after multivariate adjustments. Our results indicate that, in women with OSA, age, obesity/central obesity, and insulin resistance are major determinants of dyslipidemia. PMID:28134311

    What is the prevalence of polycystic ovary syndrome (PCOS) in Han Chinese women from different communities? The prevalence of PCOS in Chinese women aged 19-45 years is 5.6%. The prevalence of PCOS is reported to range from 5 to 10% but to the best of our knowledge the Han Chinese population has not been studied. A large-scale epidemiological study was carried out between October 2007 and September 2011 in 15 924 Han Chinese women of reproductive age (19-45 years) from the 10 provinces and municipalities in China. A total of 16 886 women from 152 cities and 112 villages were involved in the study. All study participants received a questionnaire and underwent a physical and transvaginal ultrasound examination. Blood samples were collected from a subsample of women (n = 3565) for analysis of metabolic markers and hormones. Based on the Rotterdam PCOS criteria, we assessed hyperandrogenism (H), chronic anovulation (O) and polycystic ovaries (P). Following diagnosis, women with PCOS were assigned to one of four different phenotypes. Finally, the prevalence and related risks of PCOS among Chinese women were estimated based on all the data sources. A total of 16 886 women were initially involved in the study and 15 924 eligible participants then completed the study; the overall response rate was 94.3% (15 924/16 886). The prevalence of PCOS in the Chinese community population was 5.6% (894/15 924). Blood samples were analyzed from 833 of these women who were assigned to the four PCOS phenotypes as follows: 19% H + O, 37% H + P, 15% O + P and 29% H + O + P. Comparing the 833 women with PCOS to 2732 women without PCOS indicated that PCOS occurs in younger women (P Obese patients with PCOS had a higher rate of MS (16 versus 48%), IR (7 versus 28%), hypertension (8 versus 30%) and hyperlipemia (48 versus 73%) compared with non-obese patients (all P obese, are essential in Chinese women of reproductive age.

    To determine the effects of gestational diabetes mellitus (GDM) and pre-pregnancy obesity on macrosomia and large for gestational age (LGA). We conducted a prospective cohort study of 587 GDM women and 478 non-GDM women from 2012 to 2013. We collected their data of the pre-pregnancy weight, sociodemographic data, medical histories, clinical treatment, and followed-up the outcomes of delivery including birth weight. Multiple logistic regression models were used to test associations between pre-pregnant obesity and macrosomia/LGA and between GDM and macrosomia/LGA. Of 1065 women we studied, obese women had 4.17 times and 2.27 times increased risk of developing macrosomia (95% CI: 2.52 to 6.91) and LGA (95% CI: 1.60 to 3.21), respectively, than non-obese women after adjustment for maternal age, gestational weeks and GDM. We did not find GDM is a risk factor for macrosomia or LGA after GDM treatment. Pre-pregnancy obesity accounts for a high prevalence of macrosomia. Interventions that focus on pre-pregnancy obesity have the potential to reach far more women at risk of macrosomia.

    SINCE more and more rural women have become involved in commercial production, they have become more and more eager to learn about scientific technology. The Women’s Federation of Beijing had long been looking for a direct and effective way to help them. Luo Xiaolu, vicedirector of the Federation, found in her investigation of the present conditions of intellectual women in Beijing that women students were also eager to get in touch with society. Then she had an idea that women students in universities and colleges should go to the countryside. Thus, an activity developed called "women college students and rural women, hand in hand."

  2. Unsettled women.

    2001-01-01

    SUMMARY Amy Bock (alias Percy Redwood) created a media sensation when "The Case of the Woman Bridegroom" hit the newspapers throughout New Zealand in 1909. She was hailed as the "queerest and most interesting character that has ever been before the New Zealand public" and "pitiable in her freakish exploits." Debates ensued as to whether her crimes were evidence of a mania, a disease, or simply due to a flawed, criminal character. This article focuses on media portrayals of women who did not conform to normative constructions of acceptable womanhood within the latter decades of the nineteenth century and the early twentieth century in New Zealand, as a means of tracing the mutable boundaries of intelligible genders. Newspaper debates and emergent discourses around the medicalisation of social de-viancy are drawn upon to demonstrate how normative constructions of gender were premised upon a defining matrix of mad/bad/woman.

    2013-10-01

    Full Text Available OBJECTIVE: In obesity, the excessive adipose tissue increases the synthesis of inflammatory cytokines, which appear to alter the metabolism of minerals, such as zinc. However, the mechanisms involved remain unclear. This study investigated whether the concentrations of interleukin-6 (IL-6 and tumor necrosis factor-α (TNF-α in plasma can to influence biochemical parameters of zinc in obese women. METHODS: Seventy-six pre-menopausal women, aged between 20 and 50 years, were divided into two groups: the case group, composed of obese women (n = 37 and the control group, composed of non-obese women (n = 39. Analysis of the plasmatic and erythrocytary zinc, and plasmatic cytokines were conducted by flame atomic absorption spectrophotometry and by ELISA, respectively. RESULTS: The plasmatic zinc and concentrations of IL-6 in plasma did not show significant differences between obese women and controls (p > 0.05. The erythrocytary zinc was 36.4±15.0µg/gHb in the case group, and 45.4±14.3µg/gHb (p = 0.025 in the control group. The concentrations of TNF-α in plasma were 42.0±11.9 pg/mL and 19.0±1.0 pg/mL in obese women and in controls, respectively (p < 0.001. The plasmatic zinc had a significant negative correlation with the values of TNF-α (r =-0.44, p = 0.015. CONCLUSION: Obese women presented lower concentrations of erythrocytary zinc than the control group. The study demonstrated a probable influence of the inflammatory process on metabolism of zinc in obese patients.

  16. Minority Women and Advocacy for Women's Health

    Science.gov (United States)

    Kumanyika, Shiriki K.; Morssink, Christiaan B.; Nestle, Marion

    2001-01-01

    US minority health issues involve racial/ethnic disparities that affect both women and men. However, women's health advocacy in the United States does not consistently address problems specific to minority women. The underlying evolution and political strength of the women's health and minority health movements differ profoundly. Women of color comprise only one quarter of women's health movement constituents and are, on average, socioeconomically disadvantaged. Potential alliances may be inhibited by vestiges of historical racial and social divisions that detract from feelings of commonality and mutual support. Nevertheless, insufficient attention to minority women's issues undermines the legitimacy of the women's health movement and may prevent important advances that can be achieved only when diversity is fully considered.

    2012-08-01

    What is the role of myostatin and its relationship with obesity, androgens and follistatin levels in women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWERS: The myostatin level was positively correlated to the risk of abdominal obesity, but negatively associated with circulating levels of dehydroepiandrosterone sulfate (DHEAS) and follistatin in women with PCOS. Myostatin is a well-known negative regulator of skeletal muscle and is involved in metabolism; however, little is known about the role of myostatin in women with PCOS. In this study, we found that the myostatin level was positively related to the risk of abdominal obesity, but negatively related to the circulating levels of DHEAS and follistatin in women with PCOS. Such a relationship might imply a potential regulatory role of androgens and follistatin in the metabolism of skeletal muscle in women with PCOS. A cross-sectional case-control study. A total of 239 untreated, consecutive women with PCOS and 38 healthy volunteer women without PCOS were enrolled and studied in a tertiary medical center. Myostatin level was higher in women with PCOS than those without PCOS (16.6±15.6 and 14.2±9.7, P=0.025), but were not significantly different between non-obese women with and without PCOS after considering the effect of obesity (P=0.09). Stepwise multivariate regression analysis in women revealed that only the presence of PCOS (β=0.256, P=0.0001), total testosterone (β=0.159, P=0.031), DHEAS (β=-0.188, P=0.0003) and follistatin (β=-0.171, P=0.0001) levels were left in the final model and were significantly related to the myostatin level after considering all the explanatory variables. By using stepwise multivariate regression analysis, the total testosterone levels (β=0.196, P=0.003) were positively, but the DHEAS (β=-0.196, Pobesity after further adjusting the androgens and follistatin levels in women with PCOS. This study is a cross-sectional case-control design, and therefore, cannot answer the

    Obesity is a risk factor for the development of new cases of breast cancer and also affects survival in women who have already been diagnosed with breast cancer. Early studies of obesity and breast cancer survival have been summarised in two meta-analyses, but the latest of these only included studies that recruited women diagnosed as recently as 1991. The primary aim of this study was to conduct a meta-analysis that included the more recent studies. A systematic search of MEDLINE, EMBASE and CINAHL was conducted to identify original data evaluating the effects of obesity on survival in newly diagnosed breast cancer patients. Adjusted hazard ratios (HR) from individual studies were pooled using a random effects model. A series of pre-specified sensitivity analyses were conducted on factors such as overall versus breast cancer survival and treatment versus observational cohort. The meta-analysis included 43 studies that enrolled women diagnosed with breast cancer between 1963 and 2005. Sample size ranged from 100 to 424168 (median 1192). The meta-analysis showed poorer survival among obese compared with non-obese women with breast cancer, which was similar for overall (HR = 1.33; 95% confidence interval (CI): 1.21, 1.47) and breast cancer specific survival (HR = 1.33; 95% CI: 1.19, 1.50). The survival differential varied only slightly, depending on whether body mass index (1.33; 1.21, 1.47) or waist-hip ratio (1.31; 1.08, 1.58) was used as the measure of obesity. There were larger differences by whether the woman was pre-menopausal (1.47) or post-menopausal (1.22); whether the cohort included women diagnosed before (1.31) or after 1995 (1.49); or whether the women were in a treatment (1.22) or observational cohort (1.36), but none of the differences were statistically significant. Women with breast cancer, who are obese, have poorer survival than women with breast cancer, who are not obese. However, no study has elucidated the causal mechanism and there is currently

    Hot flashes have been postulated to be linked to the development of metabolic disorders. This study aimed to evaluate the relationship between hot flashes, adipocyte-derived hormones, and insulin resistance in healthy, non-obese postmenopausal women. In this cross-sectional study, a total of 151 women aged 45-60 years were stratified into one of three groups according to hot-flash status over the past three months: never experienced hot flashes (Group N), mild-to-moderate hot flashes (Group M), and severe hot flashes (Group S). Variables measured in this study included clinical parameters, hot flash experience, fasting levels of circulating glucose, lipid profiles, plasma insulin, and adipocyte-derived hormones. Multiple linear regression analysis was used to evaluate the associations of hot flashes with adipocyte-derived hormones, and with insulin resistance. The study was performed in a hospital medical center. The mean (standard deviation) of body-mass index was 22.8(2.7) for Group N, 22.6(2.6) for Group M, and 23.5(2.4) for Group S, respectively. Women in Group S displayed statistically significantly higher levels of leptin, fasting glucose, and insulin, and lower levels of adiponectin than those in Groups M and N. Multivariate linear regression analysis revealed that hot-flash severity was significantly associated with higher leptin levels, lower adiponectin levels, and higher leptin-to-adiponectin ratio. Univariate linear regression analysis revealed that hot-flash severity was strongly associated with a higher HOMA-IR index (% difference, 58.03%; 95% confidence interval, 31.00-90.64; p adiponectin and was no longer significant after simultaneously adjusting for leptin and adiponectin. The present study provides evidence that hot flashes are associated with insulin resistance in postmenopausal women. It further suggests that hot flash association with insulin resistance is dependent on the combination of leptin and adiponectin variables.

    Blood pressure is typically lower in premenopausal women than in men. However, after menopause, the prevalence of hypertension in women is higher than it is in men. Hypertension is a major risk factor for cardiovascular disease in women and men, but cardiovascular disease is the leading cause of death in women. Furthermore, there is evidence that blood pressure may not be as well-controlled in women as in men, despite the fact that most women adhere better to their therapeutic regimens and medications than do men, and have their blood pressures measured more frequently than do men. This review describes possible mechanisms by which blood pressure may be increased in postmenopausal women.

    Microfluidics, a field that has been well-established for several decades, has seen extensive applications in the areas of biology, chemistry, and medicine. However, it might be very hard to imagine how such soft microfluidic devices would be used in other areas, such as electronics, in which stiff, solid metals, insulators, and semiconductors have previously dominated. Very recently, things have radically changed. Taking advantage of native properties of microfluidics, advances in microfluidics-based electronics have shown great potential in numerous new appealing applications, e.g. bio-inspired devices, body-worn healthcare and medical sensing systems, and ergonomic units, in which conventional rigid, bulky electronics are facing insurmountable obstacles to fulfil the demand on comfortable user experience. Not only would the birth of microfluidic electronics contribute to both the microfluidics and electronics fields, but it may also shape the future of our daily life. Nevertheless, microfluidic electronics are still at a very early stage, and significant efforts in research and development are needed to advance this emerging field. The intention of this article is to review recent research outcomes in the field of microfluidic electronics, and address current technical challenges and issues. The outlook of future development in microfluidic electronic devices and systems, as well as new fabrication techniques, is also discussed. Moreover, the authors would like to inspire both the microfluidics and electronics communities to further exploit this newly-established field.

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed.

    The main objective was to assist in the production of electronic images in the Electronic Photography Lab (EPL). The EPL is a new facility serving the electronic photographic needs of the Langley community. The purpose of the Electronic Photography lab is to provide Langley with access to digital imaging technology. Although the EPL has been in operation for less than one year, almost 1,000 images have been produced. The decision to establish the lab was made after careful determination of the centers needs for electronic photography. The LaRC community requires electronic photography for the production of electronic printing, Web sites, desktop publications, and its increased enhancement capabilities. In addition to general use, other considerations went into the planning of the EPL. For example, electronic photography is much less of a burden on the environment compared to conventional photography. Also, the possibilities of an on-line database and retrieval system could make locating past work more efficient. Finally, information in an electronic image is quantified, making measurements and calculations easier for the researcher.

    Electron bifurcation is the recently recognized third mechanism of biological energy conservation. It simultaneously couples exergonic and endergonic oxidation-reduction reactions to circumvent thermodynamic barriers and minimize free energy loss. Little is known about the details of how electron bifurcating enzymes function, but specifics are beginning to emerge for several bifurcating enzymes. To date, those characterized contain a collection of redox cofactors including flavins and iron-sulfur clusters. Here we discuss the current understanding of bifurcating enzymes and the mechanistic features required to reversibly partition multiple electrons from a single redox site into exergonic and endergonic electron transfer paths.

    The purpose of this study was to evaluate the surgical feasibility of and survival outcome after laparoscopy in obese Korean women with endometrial cancer which has recently been increasing. We reviewed the medical records of the patients treated at our medical institution between 1999 and 2012. The patients were divided into three groups, non-obese (Body Mass Index [BMI]obese (BMI≥28.0). These patient groups were compared in terms of their clinical characteristics, treatment methods, as well as surgical and survival outcomes. In total, 55 of the 278 eligible patients were obese women. There were no differences in the three groups in terms of the proportion of patients who underwent lymphadenectomy, their cancer stage, histologic type, type of adjuvant treatment administered, intra-, post-operative, and long-term complications, operative time, number of removed lymph nodes, blood loss, and duration of hospitalization (P=0.067, 0.435, 0.757, 0.739, 0.458, 0.173, 0.076, 0.124, 0.770, 0.739, and 0.831, respectively). The Disease-Free Survival (DFS) times were 139.1 vs. 121.6 vs. 135.5 months (P=0.313), and the Overall Survival (OS) times were 145.2 vs. 124.8 vs. 139.5 months (P=0.436) for each group, respectively.

    estrategia atractiva para comparar individuos con grandes diferencias en la masa corporal. OBJETIVO: Investigar el VO2pico en individuos obesos y no obesos usando el método de corrección de masa corporal (convencional y la escala alométrica (método alométrico y cómo esos métodos se aplican cuando individuos de ambos sexos se ejercitan en una cinta ergométrica. MÉTODOS: El VO2pico relativo al peso corporal y por el método alométrico fue comparado en 54 adolescentes obesos y 33 no obesos (10-16 años. Para evaluar el VO2pico durante un test máximo se utilizó calorimetría indirecta. El exponente alométrico fue calculado considerando la masa corporal individual. Así, el VO2pico fue corregido mediante el exponente alométrico. Las comparaciones se realizaron utilizando two-way ANOVA para medidas repetidas (p0,05. Sin embargo, el VO2pico calculado por el método convencional fue mayor (p0.05 entre los grupos. CONCLUSIÓN: Los individuos obesos presentaron VO2pico más bajo que los no obesos, al ser evaluados mediante el método convencional. Sin embargo, las diferencias desaparecieron cuando se aplicó el método de la escala alométrica.BACKGROUND: Peak oxygen uptake (VO2peak can be defined as the highest oxygen rate consumed during exhaustive or maximal exercise. The evaluation of the aerobic fitness can be expressed as relative to body mass, but this procedure may not fully remove differences when heavy subjects are assessed. Thus, the allometric scaling procedure is an attractive strategy to compare individuals with large differences in body mass. OBJECTIVE: Investigate VO2peak in obese and non-obese individuals using body mass correction (conventional and allometric scaling (allometric methods and how these methods apply when subjects of different genders exercise on a treadmill. METHODS: VO2peak relative to body weight and measured by the allometric method were compared in 54 obese and 33 non-obese adolescents (10 a 16 years. Indirect calorimetry was used to

    Objective To explore the clinical effectiveness and safety of laparoscopic sleeve gastrectomy-duodenojejunal bypass (LSG+DJB) in the non-obese diabetes patients.Methods The data of 12 non-obese patients with type 2 diabetes mellitus who underwent LSG+DJB from June 2012 to December 2013 were analyzed, including the length of hospitalization, operative time, blood loss, operative related complications and weight, BMI, waist circumference, fasting plasma glucose (FPG), oral glucose tolerance test, HbA1c, blood lipids and the changing of diabetes complications at pre and postoperative time of 1,3,6 and 12 months.Results All the procedures were preformed smoothly without perioperative death. Esophageal reflux symptoms such as heartburn happened to one case after the procedure, and released after conservative treatment. The FPG, HbA1c, HOMA-IR, C-peptide, weight, BMI, waist circumference, serum triglyceride (TG), low density lipoprotein cholesterol (LDL-C) of the patients were declined significantly after the procedure (P<0.05). One year after the procedures, 9 cases stopped taking medicine because of the remission of T2DM, including 3 cases completely cured (HbA1c<6.0%) and 6 cases controlled (HbA1c<7.0%), andthe other 3 cases decreased hypoglycemic agent.Conclusions LSG+DJB performed safely in non-obese patients with type 2 diabetes with the good effectiveness of controlling weights, improving blood glucose, blood lipid and related complications. The short-term effectiveness is good, but the long-term effectiveness remains further observation.%目的探讨腹腔镜袖状胃切除联合十二指肠-空肠转流术(laparoscopic sleeve gastrectomy-duodenojejunal bypass,LSG-DJB)治疗非肥胖型2型糖尿病的疗效。方法收集苏州大学附属第一医院2012年6月至2013年12月应用LSG-DJB治疗的12例非肥胖型(BMI<30 kg/m2)2型糖尿病患者的临床资料,记录患者的住院时间,手术时间,手术失血量,手术相关并

    Keizire, J

    1995-01-01

    This article discusses the prevalence of violence against women in Uganda. The incidence of violence against women has been increasing despite efforts by law enforcement orders. In the broadest sense, violence against women is any violation of a woman's personhood, mental or physical integrity or freedom of movement. Violence against women is considered as an obstacle to the achievement of the objectives of equality, development and peace. Moreover, the act violates and impairs women's rights and fundamental freedoms. The low social and economic status of women can be both a cause and a consequence of violence against women. Physical, sexual and psychological violence occurring in the family, including battering, sexual abuse of female children, dowry-related violence, marital rape, female genital mutilation and other traditional practices harmful to women, limit the ability to make choices on women's lives.

  2. Women's rights to health.

    Science.gov (United States)

    1997-08-01

    Women's rights and health are threatened by cultural, religious, and social biases against women that create barriers in women's ability to access health information, education, and services. The fact that women's basic human rights include a right to health has been incorporated in international rights covenants, but violations occur in the form of 1) direct state actions, such as coercive abortion; 2) failure of states to meet health needs; 3) discrimination that denies health care to specific groups; and 4) failure of states to protect women from violence, child marriage, female infanticide, and other forms of health- and life-threatening discrimination. In order to improve this situation, a basic set of indicators must be developed to monitor implementation of agreements to protect women. Health professionals must continue to incorporate women's rights into the ethics or charters of health practices, to improve service to women, and to increase governmental advocacy on behalf of women. Governments must acknowledge the benefits of applying a rights approach to women's health status and must develop plans to implement recommendations arising from international conferences on women's rights. Women-centered nongovernmental organizations must create a clear framework on women's rights to health and develop advocacy and networking strategies.

Instead of flat out rejecting the technology as uncontrollably dangerous, we advocate in this paper a different technological angle that renders electronic elections trustworthy beyond...... the usual levels of doubt. We exploit the trust that voters currently have into the democratic process and model our techniques around that observation accordingly. In particular, we propose a technique of trace emitting computations to record the individual steps of an electronic voting machine...... for a posteriori validation on an acceptably small trusted computing base. Our technology enables us to prove that an electronic elections preserves the voter’s intent, assuming that the voting machine and the trace verifier are independent....

    The roots, stems, leaves, and vascular circuitry of higher plants are responsible for conveying the chemical signals that regulate growth and functions. From a certain perspective, these features are analogous to the contacts, interconnections, devices, and wires of discrete and integrated electronic circuits. Although many attempts have been made to augment plant function with electroactive materials, plants’ “circuitry” has never been directly merged with electronics. We report analog and digital organic electronic circuits and devices manufactured in living plants. The four key components of a circuit have been achieved using the xylem, leaves, veins, and signals of the plant as the template and integral part of the circuit elements and functions. With integrated and distributed electronics in plants, one can envisage a range of applications including precision recording and regulation of physiology, energy harvesting from photosynthesis, and alternatives to genetic modification for plant optimization.

    More than a decade ago, women achieved parity with men in the number of matriculants to medical school, nearly one-third of the faculty of medical schools were women, and there were some women deans and department chairs. These trends were promising, but today there are still significant differences in pay, academic rank, and leadership positions for women compared with men in academic medicine. Though there has been progress in many areas, the progress is too slow to achieve previously recommended goals, such as 50% women department chairs by 2025 and 50% women deans by 2030.The author points to the findings presented in the articles from the Research Partnership on Women in Biomedical Careers in this issue, as well as research being published elsewhere, as an evidence base for the ongoing discussion of gender equity in academic medicine. More attention to culture and the working environment will be needed to achieve true parity for women in academic medical careers.

  20. Effects of anti-obesity messages on women's body image and eating behaviour.

    Shentow-Bewsh, Rachel; Keating, Leah; Mills, Jennifer S

    2016-01-01

    It has been suggested that obesity stigmatization contributes to negative mental health outcomes, particularly among overweight individuals. This study examined the effects of exposure to media-portrayed anti-obesity messages on women's state self-esteem, body esteem, and food intake. It was hypothesized that exposure to anti-obesity messages would result in decreased state self-esteem and body esteem and in increased food intake, and that these effects would be more pronounced in individuals with either higher BMI or stronger perceived pressure to be thin. Participants were randomly assigned to one of three experimental conditions in which they either: read a fictitious media article containing either anti-obesity messages or non-obesity-related health messages, or completed a neutral control task (word search). State self-esteem and body esteem were measured before and after the manipulation. Participants also completed a candy taste rating task and ad lib consumption was surreptitiously measured. There was no main effect of condition on either psychological outcome variable or on grams consumed. Higher perceived sociocultural pressure to be thin was associated with a decrease in body esteem after reading the anti-obesity article only. Having a higher BMI was associated with greater candy intake in the word search condition. This trend was also apparent in the sun exposure condition, but not in the anti-obesity condition. Exposure to anti-obesity messages appears to decrease weight-related body esteem in women who already feel strong pressure to be thin, and may lead heavier women to suppress their food intake.

  1. The association of obesity with hearing thresholds in women aged 18-40 years.

    An elevation in hearing thresholds and decrease in hearing sensitivity in adults, particularly due to aging, are quite common. Recent studies have shown that, apart from aging, various other factors also play a role in auditory changes. Studies on the association of hearing loss (HL) with obesity are limited in advanced age cases and present contradictions. In this study, the association between obesity and hearing thresholds in women aged 18-40 years has been assessed. Forty women diagnosed with obesity (mean age, 31.8 years) and 40 healthy non-obese female controls (mean age, 30.5 years) were included in this prospective study. Each subject was tested with low (250, 500, 1000 and 2000 Hz) and high (4000, 6000 and 8000 Hz) frequency audiometry. In the case and control groups, the average hearing thresholds at low frequencies were 16.03 ± 4.72 and 16.15 ± 2.72 (p = 0.885) for the right ear, respectively, and 16.15 ± 5.92 and 14.71 ± 3.18 (p = 0.180) for the left ear, respectively. The average hearing threshold levels at high frequencies were 20.70 ± 10.23 and 15.33 ± 3.87 (p = 0.003), respectively, for the right ear, and 22.91 ± 15.54 and 15.87 ± 4.35 (p = 0.007), respectively, for the left ear with statistical significance. This is the first report on the association of obesity with hearing threshold in women aged 18-40 years. We have demonstrated that obesity may affect hearing function, particularly that related to high frequencies. Hearing loss can be prevented by avoidance or control of obesity and its risk factors. Moreover, an auditory screening of obese cases at an early stage may provide early diagnosis of HL and may also contribute to their awareness in the fight against obesity.

  12. Making women's voices heard: technological change and women's employment in Malaysia.

    Science.gov (United States)

    Ng Choon Sim, C

    1999-01-01

    This paper examines the 1994-96 UN University Institute for New Technologies policy research project on technological change and women's employment in Asia. The project was conducted to provide a voice for nongovernmental organizations (NGOs) representing women workers. It focuses on the Malaysian experience in terms of the impact of technology on women's work and employment in the telecommunications and electronic industry. The results of the NGO research project revealed that the shift to a more intensive production has no uniform impact on women. Although new jobs were created, women employment status remains vulnerable. Meaning, female workers are afraid of the technological redundancy, casualization of labor, as well as health and safety hazards associated with new technology. A good example of the effect of industrialization to women¿s rights is the situation in Malaysia. Although cutting edge technology, combined with restructuring, has yielded some benefits in terms of a vastly expanded network and services, better performances and economies of scale, employment situation of the majority of women still remained in the low-skilled or semi-skilled categories. In order to upgrade women employment status along with the technological advancement, open communication and cooperation of all types is needed to ensure a successful outcome.

    Siegbahn, Kai

    Wilhelm Conrad Röntgen's discovery of X radiation in 1895 in Wörzburg resulted in an immediate break-through not only in physics but also in Society, the latter mainly because of its sensational radiological applications. Within a short time it furthermore indirectly led to the discovery of radioactivity by Henri Becquerel. The discovery of X radiation opened the gate to modern atomic physics, and radioactivity to nuclear physics. Later on, the discovery of X-ray diffraction by Laue, Friedrich and Knipping in 1912 initiated the field of X-ray spectroscopy with its fundamental contributions to atomic and crystal structures. Secondary electrons were early observed in the scattered radiation when X-rays were hitting a sample. The development of the corresponding electron spectroscopy had to wait a much longer time for its maturity. A survey of electron spectroscopy is presented.

    2007-08-01

    The number of women in medicine has increased dramatically in the last few decades, and women now represent half of all incoming medical students. Yet residency training still resembles the historical model when there were few women in medicine. This article reviews the issues facing women in residency today. Data suggest that the experience of female residents is more negative than that of males. Unique challenges facing female residents include the existence of gender bias and sexual harassment, a scarcity of female mentors in leadership positions, and work/family conflicts. Further research is needed to understand the experience of female residents and to identify barriers that hinder their optimal professional and personal development. Structural and cultural changes to residency programs are needed to better accommodate the needs of female trainees.

    Women scientists generally play a great role in the public acceptance (PA) for the national policy of atomic energy developing in Japan. The reason may be that, when a woman scientist stands in the presence of women audience, she will be ready to be accepted by them as a person with the same gender, emotion and thought to themselves. A case of interchange between the Rokkasho women and the women scientists either resident at the nuclear site of Rokkasho or staying for a short time at Rokkasho by invitation has been described from the viewpoint of PA for the national policy of atomic energy developing, and more fundamentally, for promotion of science education.

  16. Electronic detectors for electron microscopy.

    Science.gov (United States)

    Faruqi, A R; McMullan, G

    2011-08-01

    Electron microscopy (EM) is an important tool for high-resolution structure determination in applications ranging from condensed matter to biology. Electronic detectors are now used in most applications in EM as they offer convenience and immediate feedback that is not possible with film or image plates. The earliest forms of electronic detector used routinely in transmission electron microscopy (TEM) were charge coupled devices (CCDs) and for many applications these remain perfectly adequate. There are however applications, such as the study of radiation-sensitive biological samples, where film is still used and improved detectors would be of great value. The emphasis in this review is therefore on detectors for use in such applications. Two of the most promising candidates for improved detection are: monolithic active pixel sensors (MAPS) and hybrid pixel detectors (of which Medipix2 was chosen for this study). From the studies described in this review, a back-thinned MAPS detector appears well suited to replace film in for the study of radiation-sensitive samples at 300 keV, while Medipix2 is suited to use at lower energies and especially in situations with very low count rates. The performance of a detector depends on the energy of electrons to be recorded, which in turn is dependent on the application it is being used for; results are described for a wide range of electron energies ranging from 40 to 300 keV. The basic properties of detectors are discussed in terms of their modulation transfer function (MTF) and detective quantum efficiency (DQE) as a function of spatial frequency.

  17. First Mayan Women's Congress.

    Teissedre, S

    1997-01-01

    In October 1997, over 200 participants attended the First Mayan Women's Congress in Mexico and called for financial assistance, capacity building, and training to help Mayan women escape poverty. The Congress was initiated by the UN Development Fund for Women in collaboration with the Small Grants Program of the UN Development Program. Traditionally, Mayan women and men have played distinct roles in society, and efforts are underway to increase gender sensitivity and achieve a new balance of power. Mayan women attending the Congress reported that they face daily challenges in gaining their husbands' approval for participation in income-generating activities outside of the home. Eventually, however, some husbands also start working in these enterprises and are learning to assume their share of domestic responsibilities. Mayan women have been forced to reevaluation their role in society by a prevailing agricultural and environmental crisis as well as a high unemployment rate. Crafts that were once produced only for household consumption are now considered for export. Because the women need funds to initiate income-generating activities, the Conference linked women's groups with development practitioners, policy-makers, and donors. The women requested financial aid for more than 30 specific projects, and Congress participants agreed to pursue innovate strategies to support the enterprises with funds, training, and technical assistance. The Congress also encouraged environmental nongovernmental organizations to include Mayan women in mainstream development activities. This successful Congress will be duplicated in other Mexican states.

  18. Women and political representation.

    Science.gov (United States)

    Rathod, P B

    1999-01-01

    A remarkable progress in women's participation in politics throughout the world was witnessed in the final decade of the 20th century. According to the Inter-Parliamentary Union report, there were only eight countries with no women in their legislatures in 1998. The number of women ministers at the cabinet level worldwide doubled in a decade, and the number of countries without any women ministers dropped from 93 to 48 during 1987-96. However, this progress is far from satisfactory. Political representation of women, minorities, and other social groups is still inadequate. This may be due to a complex combination of socioeconomic, cultural, and institutional factors. The view that women's political participation increases with social and economic development is supported by data from the Nordic countries, where there are higher proportions of women legislators than in less developed countries. While better levels of socioeconomic development, having a women-friendly political culture, and higher literacy are considered favorable factors for women's increased political representation, adopting one of the proportional representation systems (such as a party-list system, a single transferable vote system, or a mixed proportional system with multi-member constituencies) is the single factor most responsible for the higher representation of women.

    The role of women in family businesses is explored in the paper. Although recognized as generally very important players, the role of women is often defined as invisible in business decision-making, supportive in men’s traditional business domains and only rarelyadequately recognized and rewarded. The paper explores possible differences in the views of men and women who manage small family firms. Their attitudes opposing the traditional business roles ofwomen, different views on managerial, o...

    CURRENTLY, the ageing of the population has created problems for a developing China. Jiangsu is one of the provinces that has encountered these problems, where the average lifespan for women is 73. Women aged 40 to 55 who are going through menopause account for about 8 percent of Jiangsu’s total population. Whether this group is able to live a healthy life during menopause or not decides whether the women are healthy and happy and influences the rest of society.

  4. Women's empowerment: what works

    OpenAIRE

    Andrea, Cornwall

    2016-01-01

    With radical roots in the 1980s, women’s empowerment is now a mainstream development concern. Much of the narrative focuses on instrumental gains—what women can do for development rather than what development can do for women. Empowerment is treated as a destination reached through development’s equivalent of motorways: programmes rolled out over any terrain. But in the process, pathways women are travelling in their own individual or collective journeys of empowerment remain hidden. Revisiti...

    Advances in gender equality have been sought in the field of medicine for centuries, including the specialty of otolaryngology. Currently, about 14.5% of practicing otolaryngologists are women. Strides have been made to support equality by the American Academy of Otolaryngology-Head and Neck Surgery through the development of the Women in Otolaryngology Section in 2010, among other efforts. This article reviews the literature of women in otolaryngology, as well as current trends toward equality among otolaryngologists of all genders.

    1960-04-01

    A pulsed electron gun capable of delivering pulses at voltages of the order of 1 mv and currents of the order of 100 amperes is described. The principal novelty resides in a transformer construction which is disposed in the same vacuum housing as the electron source and accelerating electrode structure of the gun to supply the accelerating potential thereto. The transformer is provided by a plurality of magnetic cores disposed in circumferentially spaced relation and having a plurality of primary windings each inductively coupled to a different one of the cores, and a helical secondary winding which is disposed coaxially of the cores and passes therethrough in circumferential succession. Additional novelty resides in the disposition of the electron source cathode filament input leads interiorly of the transformer secondary winding which is hollow, as well as in the employment of a half-wave filament supply which is synchronously operated with the transformer supply such that the transformer is pulsed during the zero current portions of the half-wave cycle.

    Our objectives were to determine whether migrant women in Western industrialized countries have higher odds of inadequate prenatal care (PNC) compared to receiving-country women and to summarize factors that are associated with inadequate PNC among migrant women in these countries. We conducted searches of electronic databases (MEDLINE, EMBASE, and PsycINFO), reference lists, known experts, and an existing database of the Reproductive Outcomes And Migration international research collaboration for articles published between January, 1995 and April, 2010. Title and abstract review and quality appraisal were conducted independently by 2 reviewers using established criteria, with consensus achieved through discussion. In this systematic review of 29 studies, the majority of studies demonstrated that migrant women were more likely to receive inadequate PNC than receiving-country women, with most reporting moderate to large effect sizes. Rates of inadequate PNC among migrant women varied widely by country of birth. Only three studies explored predictors of inadequate PNC among migrant women. These studies found that inadequate PNC among migrant women was associated with being less than 20 years of age, multiparous, single, having poor or fair language proficiency, education less than 5 years, an unplanned pregnancy, and not having health insurance. We concluded that migrant women as a whole were more likely to have inadequate PNC and the magnitude of this risk differed by country of origin. Few studies addressed predictors of PNC utilization in migrant women and this limits our ability to provide effective PNC in this population.

    The participation of women in higher education in Mexico took place in the late 19th and early 20th century. The rise of women's enrollment in universities known as the "feminization of enrollment" occurred in the last thirty years. In this review we analyze how the new conditions that facilitated better access to higher education are reflected in the inclusion of women in science. We include an overview of the issues associated with a change in the demographics of enrollment, segregation of academic areas between men and women and participation in post graduate degrees. We also review the proportion of women in science. While in higher education the ratio between male and women is almost 50-50 and in some areas the presence of women is even higher, in the field of scientific research women account for barely 30% of professionals. This is largely due to structural conditions that limit the access of women to higher positions of power that have been predominantly taken by men.

    Several important questions emerge from the study of gender differences in schizophrenia: Why does schizophrenia begin later in women? Why is outcome superior in women, at least in the first 15 years after onset? What causes sex differences in symptoms? What can gender differences teach us about the etiology of schizophrenia? Do men and women require substantially different treatments? What interventions during pregnancy and after childbirth ensure optimal health for the children of mothers with schizophrenia? Although complete answers may not yet be forthcoming, it is important to define the questions and keep them in mind when delivering services to women suffering from this severe, persistent mental illness.

    1997-01-01

    This article discusses the problems that women face in social, health, and nutritional areas in India. India's 135th ranking in the Human Development Index reflects the marginalization of women, the aged, the poor, the disabled, lower castes, and other neglected groups. The sex ratio has declined. Maternal mortality is high. 84% of rural women and 42% of urban women rely on untrained persons during childbirth. The systems of education, religion, health care, law, employment, and the mass media promote gender discrimination. Patriarchal structures resist efforts to build a gendered perspective and to provide gender sensitivity within health care and development. Women experience deficits in educational development, rest, food, recreation, and freedom of movement and action. Girls lack sufficient breast feeding and health care from a health system that is 80% private. 40% of the population is poor and needs access to affordable health services. Inadequate diets and nutrition have long term health consequences. Women's health deteriorates due to early marriage and childbearing. Adequate nutrition is exacerbated by high food prices, limits in the Public Distribution System, and the shift to non-edible cash crops. The family planning program focuses on women, despite the prevailing belief that women are not in a position to make decisions. Responsible use of modern contraception requires adequate health infrastructure, personnel, and gender sensitivity. The new emphasis on reproductive health must address the issues of unsafe abortion, reproductive tract infections, women's domestic burden, violence, and mental health.

  18. The Relationship of Fat Distribution and Insulin Resistance with Lumbar Spine Bone Mass in Women.

    Directory of Open Access Journals (Sweden)

    Francisco J A de Paula

    Full Text Available Bone marrow harbors a significant amount of body adipose tissue (BMAT. While BMAT might be a source of energy for bone modeling and remodeling, its increment can also represent impairment of osteoblast differentiation. The relationship between BMAT, bone mass and insulin sensitivity is only partially understood and seems to depend on the circumstances. The present study was designed to assess the association of BMAT with bone mineral density in the lumbar spine as well as with visceral adipose tissue, intrahepatic lipids, HOMA-IR, and serum levels of insulin and glucose. This cross-sectional clinical investigation included 31 non-diabetic women, but 11 had a pre-diabetes status. Dual X-ray energy absorptiometry was used to measure bone mineral density and magnetic resonance imaging was used to assess fat deposition in BMAT, visceral adipose tissue and liver. Our results suggest that in non-diabetic, there is an inverse relationship between bone mineral density in lumbar spine and BMAT and a trend persists after adjustment for weight, age, BMI and height. While there is a positive association between visceral adipose tissue and intrahepatic lipids with serum insulin levels, there is no association between BMAT and serum levels of insulin. Conversely, a positive relationship was observed between BMAT and serum glucose levels, whereas this association was not observed with other fat deposits. These relationships did not apply after adjustment for body weight, BMI, height and age. The present study shows that in a group of predominantly non-obese women the association between insulin resistance and BMAT is not an early event, as occurs with visceral adipose tissue and intrahepatic lipids. On the other hand, BMAT has a negative relationship with bone mineral density. Taken together, the results support the view that bone has a complex and non-linear relationship with energy metabolism.

    Arnaud Laillou

    Full Text Available INTRODUCTION: In many developing countries including Vietnam, data are lacking on vitamin D and calcium deficiencies whereas those deficiencies can play an important role in the development of bone health and possibly non-communicable diseases. The purpose of this study was to determine the overall prevalence of vitamin D and calcium deficiencies in women and young children and their nutritional related risk factors. METHODS: A cross-sectional study conducted among 595 women of reproductive age and 532 children <5 years from 19 provinces of Vietnam. For each individual, data concerning daily diet, socioeconomic group, anthropometric status were obtained, and plasma concentrations of calcium and vitamin D were measured. RESULTS: The prevalence of hypovitaminosis D status was very high, with the prevalence of vitamin D deficiency (25(OHD<30 nmol/L and insufficiency (25(OHD between 30-49.9 nmol/L being 17% and 40% in women and 21% and 37% in children, respectively. Using more liberal cut-off of 75 nmol/L, approximately 90% of the women and children were classified as having hypovitaminosis D. Overweight/obese women had a 2 times lower risk (OR = 0.46, [0.24-0.90] for vitamin D deficiency than non-overweight and non-obese women. No participant had severe calcium deficiency but moderate and mild hypocalcaemia (plasma calcium concentrations between 1.15-0.9 mmol/L for mild deficiency and between 0.9-0.8 mmol/L for moderate deficiency affected respectively 14% and 83% of the women with 97% of the children having mild hypocalcaemia. Women and children consumed about 1% of the Institute of Medicine (IOM recommended nutrient intake (RNI for vitamin D and less than 43% of the RNI for calcium. CONCLUSION: Our study suggests that calcium and vitamin D deficiencies represent a major public health concern in Vietnam. Thus, actions to improve the vitamin D and calcium status of the Vietnamese population should be considered.

    This document dealing with women's lives and the health of mothers identifies factors conditioning the health and nutritional status of women and girls (life expectancy at birth, maternal mortality rate, and the birthrate); considers nutritional requirements of pregnant and lactating women, weight gain during preganncy, mothers' age and number of children and interbirth interval, maternal nutritional status and breastfeeding, anemia, work and women's health, pregnancy in adolescents, abortion, the growth of small girls and its effect on future pregnancies, and sexual mutilations; and reports on actions aimed at improving the health of women as well as health problems facing rural women. The 3 key concepts of this reflection on women's lives are: women's health should be taken into account as well as children's health; the development of the whole human being should be respected, implying ongoing surveillance of the health status of women and of their children; and the overall living conditions of women within the family and society must be analyzed at the different phases of their life, so as to encourage integrated actions rather than various uncoordinated efforts. Women's health status, like the health status of everyone, depends on a multitude of socioeconomic and sanitational factors. A figure illustrates several of the many interrelations between the various factors which influence the nutritional status of all individuals. Women of childbearing age are at greater risk than other population groups, due to their reproductive function and their ability to nurse children: pregnancy, like lactation, generates metabolic changes and increases nutritional needs. Delivery itself presents a series of risks for the woman's health, and only regular surveillance of pregnancy may prevent many of these. A woman's health status and, most of all her nutritional status during pregnancy and delivery, condition her future health and ability to assume her many tasks as well as

    Background There are considerable controversies over the adverse effects of hyperglycemia and tight glucose control on cardiovascular outcomes in type 2 diabetes patients. Objective This study compared aortic en-dothelium-dependent vasodilation between obese type 2 diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats and non-obese diabetic Goto-Kakizaki (GK) rats. The roles of insulin in endothelium-dependent vasodilation, as well as the mechanism of hyperglycemia/hyperosmolarity in relation to endothelial nitric oxide synthase (eNOS)/ heme oxygenase (HO), was examined. Methods ① The thoracic aortae from both OLETF and GK rats of 24 weeks were isolated and vasodilatory function was assessed in vitro. Segments of the aortae were used for eNOS/ HO determination with immunofluorescence. ② One group of GK rats were injected with insulin for 10 d before observing vasodilatory function and ultrastructure of the intima. ③Normal aortic segments were incubated in the buffer of hyperglycemia or hyperosmolarity (by adding 50 mmol/L glucose or mannitol to Krebs-Henseleit buffer, 350 mOsm/L) for 5 h and contents of eNOS/HO were examined with Western blotting.Results①Compared withnon-diabetic controls, blood glucose levels of both OLETF and GK rats were significantly elevated, with the level of GK rats higher than that of OLETF rats [GK (15. 6 ±2. 5) mmol/L vs OLETF (9. 9±0. 4) mmol/L,P<0. 01]. Serum insulin level in OLETF rats was higher than that of GK rats[OLETF (11. 5±1. 2) vs GK (2. L±0. 2)μg/L, P<0. 01].②While OLETF rats' aortae showed significantly reduced endothelium-dependent vasodilation with decreased eNOS level, GK had enhanced vasodilation with increased eNOS and HO. The endothelium-dependent vasodilation in OLETF could be blocked completely by the inhibition of eNOS, while concomitant blockade of eNOS and HO was indispensable for complete inhibition of endothelium-dependent vasodilation in GK rats.③Insulin administration for GK rats induced

    The electronic properties of solids have become of increasing importance in the age of information technology. The study of solids and materials, while having originated from the disciplines of physics and chemistry, has evolved independently over the past few decades. The classical treatment of solid-state physics, which emphasized classifications, theories and fundamental physical principles, is no longer able to bridge the gap between materials advances and applications. In particular, the more recent developments in device physics and technology have not necessarily been driven by new conc

    Science.gov (United States)

    Price, Vera H

    2003-06-01

    Androgenetic alopecia (AGA), also known in women as female pattern hair loss, is caused by androgens in genetically susceptible women and men. The thinning begins between ages 12 and 40 years, the inheritance pattern is polygenic, and the incidence is the same as in men. In susceptible hair follicles, dihydrotestosterone binds to the androgen receptor, and the hormone-receptor complex activates the genes responsible for the gradual transformation of large terminal follicles to miniaturized follicles. Both young women and young men with AGA have higher levels of 5alpha reductase and androgen receptor in frontal hair follicles compared to occipital follicles. At the same time, young women have much higher levels of cytochrome p-450 aromatase in frontal follicles than men who have minimal aromatase, and women have even higher aromatase levels in occipital follicles. The diagnosis of AGA in women is supported by early age of onset, the pattern of increased thinning over the frontal/parietal scalp with greater density over the occipital scalp, retention of the frontal hairline, and the presence of miniaturized hairs. Most women with AGA have normal menses and pregnancies. Extensive hormonal testing is usually not needed unless symptoms and signs of androgen excess are present such as hirsutism, severe unresponsive cystic acne, virilization, or galactorrhea. Topical minoxidil solution is the only drug available for promoting hair growth in women with AGA. Efficacy has been shown in double-blind studies using hair counts and hair weight.

    Women in the world have made great contributions to science. In Iran more than 60% of undergraduate university students are women, most in physics. Women's representation in postgraduate studies is lower; however, these numbers do not account for those who go to other countries to continue their studies, of which there are many. Alinoush Tarian, the oldest woman professor in Iran, the first Iranian woman professor of physics, and the founder of the first solar telescopic observatory in Iran, is one of them. There are some women physicists in Iran that are working as professors at the universities and famous institutes such as the Institute for Studies in Theoretical Physics and Mathematics. Iranians have always showed their talents and intelligence everywhere in the world, and nowadays, some of the women physics teachers in Iran are trying to teach physics with new methods to attract more students.

    Women's basketball has changed over time. It is a faster paced game than it was 30 years ago. Greatplayers, like Anne Meyers,who was the first, and only, woman to be signed to an NBA contract, would agree today's game is different. The game is played mostly "below the rim" but with players like Candice Parker, Sylvia Fowles and Maya Moore able to dunk the ball, the game is still changing. The one thing that remains constant in basketball, especially women's basketball, is injury. The majority of injuries in women's basketball are similar to those in men's basketball. Studies at the high school and college level show similar injury rates between women and men. ACL injuries are one exception, with female athletes having atwo to four times higher rate ofACL injuries. In this article, we review the common injuries in women's basketball. We discuss treatment issues and possible preventive measures.

Summaries were presented and discussed...... is associated with an inherited thrombophilia in men and women. Changes in the coagulation system and in the risk of clinical VTE in women also occur during pregnancy, with the use of reproductive hormones and as a consequence of ovarian stimulation when hyperstimulation syndrome and conception occur together...... therapy (HRT) increases the VTE risk 2- to 4-fold. There is a synergistic effect between thrombophilia and the various reproductive risks. Prevention of VTE during pregnancy should be offered to women with specific risk factors. In women who are at high risk, CHC and HRT should be avoided. CONCLUSIONS...

    Electronic Router (E-Router) is an application program for routing documents among the cognizant individuals in a government agency or other organization. E-Router supplants a prior 14 NASA Tech Briefs, May 2005 system in which paper documents were routed physically in packages by use of paper slips, packages could be lost, routing times were unacceptably long, tracking of packages was difficult, and there was a need for much photocopying. E-Router enables a user to create a digital package to be routed. Input accepted by E-Router includes the title of the package, the person(s) to whom the package is to be routed, attached files, and comments to reviewers. Electronic mail is used to notify reviewers of needed actions. The creator of the package can, at any time, see the status of the package in the routing structure. At the end of the routing process, E-Router keeps a record of the package and of approvals and/or concurrences of the reviewers. There are commercial programs that perform the general functions of E-Router, but they are more complicated. E-Router is Web-based, easy to use, and does not require the installation or use of client software.

The Havana Declaration condemned the US embargo against Cuba. Fidel Castro spoke and expressed gratitude for the strong support from world women, especially Vietnamese women.

  12. Do women lack ambition?

    Science.gov (United States)

    Fels, Anna

    2004-04-01

    For men, ambition is considered a necessary and desirable part of life. Most women, however, associate ambition with egotism, self-aggrandizement, or manipulation. Getting to the bottom of why this is so required study of what ambition consists of--for both sexes. In childhood, the research uncovered, girls are clear about their ambitions. Their goals are grand, and they make no apologies for them. In nearly all childhood ambitions, two distinct factors are in place: the mastery of a special skill, and recognition for it. And what's true in childhood is no less true in later life: We all want our efforts and accomplishments acknowledged. Yet there are dramatic differences in how women and men create, reconfigure, and realize (or abandon) their goals. Most women are demure when praised for their achievements. One could chalk up this behavior to women's innate modesty or see it as a passive way of highlighting their accomplishments. But the fear of recognition that many women express suggests otherwise. Research has shown that such behavior varies according to social context: Women more openly seek and compete for affirmation when they are with other women, but they behave differently when competing with men. The underlying problem has to do with cultural ideals of femininity. Women face the reality that to appear feminine, they must provide or relinquish scarce resources to others--and recognition is indeed a scarce resource. Although women have more opportunities than ever before, they still come under social scrutiny that makes hard choices--such as when and whether to start a family or advance in the workplace--even harder. There are no easy solutions, but there are ways women can hold fast to their dreams. They must band together, learn to blow their own horns, and structure their lives in a way that promotes recognition.

  13. HIV in women

    2012-11-01

    Full Text Available Globally over 50% of HIV-infected individuals are women. With the widespread use of HAART, we can expect women to have mortality rates approaching normal. Indeed, studies have shown that women may expect a slower disease progression than men following seroconversion; furthermore, it appears that female who injects drugs can live longer than their male counterparts. However, other studies from cohort analysis have reported worse outcomes in women. In essence, many studies are consistently underpowered to adequately address these questions. The proportion of women in clinical trials remains at 20 to 30%, with pregnancy potential being a major exclusion factor. Hence, many questions remain unanswered. Recent data suggest women are more likely to present late with a new AIDS diagnosis. Why this should be the case is not well understood. In addition, HIV-positive women should have the same access to reproduction health as their negative counterparts, but unfortunately many inequalities remain. Advise on contraception and fertility services are very variable across both the developed and developing world. Data are limited on the most appropriate use of contraceptives in the presence of HAART, the possible drug interactions and possible increased risk of HIV transmission. There remain significant differences in guidelines regarding prevention of mother-to-child transmission (MTCT across Europe, and implications of stopping and starting HAART for MTCT have not been adequately addressed. The mode of timing of delivery, and the effect of length of time of ruptured membranes on this decision is also contentious. Further issues relate to the desire for HIV-positive women to breastfeed in the setting of HIV viral suppression, where some guidelines now support women in this situation and others categorically would inform child protection authorities. Finally as women age it is more difficult to separate the effect of the menopause and its symptoms from the

    Full Text Available The role of women in family businesses is explored in the paper. Although recognized as generally very important players, the role of women is often defined as invisible in business decision-making, supportive in men’s traditional business domains and only rarelyadequately recognized and rewarded. The paper explores possible differences in the views of men and women who manage small family firms. Their attitudes opposing the traditional business roles ofwomen, different views on managerial, ownership and transition issues and possible gender discrimination are examined. The findings support the paradigm of a different, more feminine style of management, while signs of discrimination are not clearly revealed. This paper is based on a research intended to provide acomparative analysis of the status of women entrepreneurs and men entrepreneurs in Family Business in India. It first draws demographic & psychographic profiles of women and men entrepreneurs in family business, identifies & addresses operational problems faced by women and men entrepreneurs in family business, draws theirinclination for future plans for growth and expansion and also for the furtherance of research on women entrepreneurs in India.

  2. HIV, poverty and women.

    Science.gov (United States)

    Rodrigo, Chaturaka; Rajapakse, Senaka

    2010-03-01

    This review examines the interactions of financial status and HIV and its implications for women. MEDLINE and Google scholar were searched using the keywords 'women', 'poverty' and 'HIV' in any field of the article. The search was limited to articles published in English over the last 10 years. The first section of the article tries to establish whether poverty or wealth is a risk factor for HIV. There is credible evidence for both arguments. While wealth shows an increased risk for both sexes, poverty places women at a special disadvantage. The second section explains how the financial status interacts with other 'non biological' factors to put women at increased risk. While discrimination based on these factors disadvantage women, there are some paradoxical observations that do not fit with the traditional line of explanation (e.g. paradoxical impact of wealth and education on HIV). The final section assesses the impact of HIV in driving poverty and the role of women in interventional programmes. The specific impact of poverty on females in families living with HIV is less explored. Though microfinance initiatives to empower women are a good idea in theory, the actual outcome of such a programme is less convincing.

There have been several laws to protect women from many centuries in this ancient country. Yet our country is still facing difficulties in achieving women safety. And the situation is no different in the rest of the world. The prevailing situation, laws and suggestions to prevent atrocities were discussed. AIM: The current situations of women hardships around the world were mentioned. The current legal situation and recent legal changes were described. The mammoth task ahead of us to achieve the desired social objective of women safety and respect were discussed. MATERIAL & METHODS: various news articles, police journals, legal textbooks and forensic medicine text books. CONCLUSION: Many things were done to prevent sexual assaults on women, yet the true goal is still a mirage. It’s time to look into the issue from its true grass root levels, i.e., from the psycho-social view apart from legal measures, to achieve the much desired objective of prevention of sexual assaults on women.

    Population is estimated to increase from 5.5 billion in 1990 to 10 billion by 2050; the poverty level is expected to increase from 1 billion to 2-3 billion people. Women in development has been promoted throughout the UN and development system, but women in poverty who perform work in the informal sector are still uncounted, and solutions are elusive. The issue of extreme poverty can not be approached as just another natural disaster with immediate emergency relief. Many people live in precarious economic circumstances throughout their lives. Recent research reveals a greater understanding of the underlying causes and the need for inclusion of poor women in sustainable development. Sanitation, water, housing, health facilities need to be improved. Women must have access to education, opportunities for trading, and loans on reasonable terms. UNESCO makes available a book on survival strategies for poor women in the informal sector. The profile shows common problems of illiteracy, broken marriages, and full time involvement in provision of subsistence level existence. Existence is a fragile balance. Jeanne Vickers' "Women and the World" offers simple, low cost interventions for aiding extremely poor women. The 1992 Commission on the Status of Women was held in Vienna. Excerpts from several speeches are provided. The emphasis is on some global responses and an analysis of solutions. The recommendation is for attention to the gender dimension of poverty. Women's dual role contributes to greater disadvantages. Women are affected differently by macroeconomic factors, and that there is intergenerational transfer of poverty. Social services should be viewed as investments and directed to easing the burdens on time and energy. Public programs must be equipped to deal with poverty and to bring about social and economic change. Programs must be aware of the different distribution of resources within households. Women must be recognized as principal economic providers within

    Each year more than 600000 women have deaths associated with cigarette smoking. In addition, cigarette smoking is associated with a wide array of morbidities (such as osteoporosis, cardiovascular disease, and adverse pregnancy outcomes). Two hundred million women smoke worldwide, and this number appears to be rising, particularly in developing countries. Obstetrician-gynecologists can play a role in reducing morbidity and mortality from cigarette smoking by educating women about the dangers, advising them not to smoke, and assisting those who do smoke to quit.

    Of the nearly 32 million Americans with migraine, 24 million are women. It is a disorder affecting women throughout their lifetimes, from childhood and puberty through the postmenopausal years. In childhood, before puberty girls are afflicted with migraine at approximately the same rate as boys, but after puberty, there is an emerging female predominance. Estrogen plays a key role in this epidemiologic variation but is not the only factor. There are numerous times when hormonal influences have an impact on migraine and its pattern, including menarche, oral contraceptive use, pregnancy, perimenopause, and menopause. Hence practitioners treating women with migraine need to have a clear understanding of these special considerations.

    We review the contributions of women to astronomy starting from the antique Greece and Alexandria, and mention briefly some works of nun-scientists in the Middle Ages, which are of interest only for keeping alive the spirit of inquiry during this Dark Age. We discuss in more details important contributions coming after the Scientific Revolution and Enlightenment, made by women working within their families, as assistants to their brothers or husbands. We show that by the late 19th century the role of women in astronomy becomes more independent, with more women working not only as "computers" in the great observatories, but also making important discoveries that placed them in a very high position as scientists at the dawn of 20th century.
