    Obesity is characterized by increased adipose tissue mass resulting from a chronic imbalance between energy intake and expenditure. Furthermore, there is a clearly defined relationship among fat mass expansion, chronic low-grade systemic inflammation and reactive oxygen species (ROS) generation; leading to ROS-related pathological events. In the past years, genome-wide association studies have generated convincing evidence associating genetic variation at multiple regions of the genome with traits that reflect obesity. Therefore, the present study aimed to evaluate the relationships among the gene polymorphisms ghrelin (GHRL-rs26802), ghrelin receptor (GHSR-rs572169), leptin (LEP-rs7799039), leptin receptor (LEPR-rs1137101) and fat mass and obesity-associated (FTO-rs9939609) and obesity. The relationships among these gene variants and the amount of DNA damage were also investigated. Three hundred Caucasian morbidly obese and 300 eutrophic (controls) women were recruited. In summary, the results demonstrated that the frequencies of the GHRL, GHSR, LEP and LEPR polymorphisms were not different between Brazilian white morbidly obese and eutrophic women. Exceptions were the AA-FTO genotype and allele A, which were significantly more frequent in obese women than in the controls (0.23% vs. 0.10%; 0.46 vs. 0.36, respectively), and the TT-FTO genotype and the T allele, which were less frequent in morbidly obese women (p<0.01). Furthermore, significant differences in the amount of genetic lesions associated with FTO variants were observed only in obese women. In conclusion, this study demonstrated that the analyzed SNPs were not closely associated with morbid obesity, suggesting they are not the major contributors to obesity. Therefore, our data indicated that these gene variants are not good biomarkers for predicting risk susceptibility for obesity, whereas ROS generated by the inflammatory status might be one of the causes of DNA damage in obese women, favoring

    Obesity has been associated with increased risk for postoperative CSF leak in patients with benign cranial nerve tumors. Other measures of postoperative morbidity associated with obesity have not been well characterized. Patients enrolled in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013 with a diagnosis code of a benign neoplasm of a cranial nerve were included. The primary outcome of postoperative morbidity was analyzed as well as secondary outcomes of readmission and reoperation. The main covariate of interest was body mass index (BMI). A total of 561 patients underwent surgery for a benign cranial nerve neoplasm between 2007 and 2013. Readmission data, available for 2012-2013(n=353), revealed hydrocephalus, facial nerve injury, or CSF leak requiring readmission or reoperation occurred in 0.85%, 1.42%, and 3.12%, respectively. Composite morbidity included wound complications, infection, respiratory insufficiency, transfusion requirement, stroke, venous thromboembolism, coma and cardiac arrest. On multivariable analysis patients with class I (BMI 30-34.9) and II (BMI 35-39.9) obesity showed trends towards increasing return to operating room, though not significant, but there was no trend for composite complications in class I and II obesity patients. However, class III obesity, BMI≥40, was associated with increased odds of composite morbidity (OR 4.40, 95% CI 1.24-15.88) and return to the operating room (OR 5.97, 95% CI 1.20-29.6) relative to patients with a normal BMI, 18.5-25. Obesity is an independent and important risk factor for composite morbidity in resection of benign cranial nerve neoplasms, and as such, merits discussion during preoperative counseling.

    Extremes in body weight are a relative contraindication to cardiac transplantation. We retrospectively reviewed 474 consecutive adult patients (377 male, 97 female, mean age 50.3+/-12.2 years), who received 444 primary and 30 heart retransplants between January of 1992 and January of 1999. Of these, 68 cachectic (body mass index [BMI]27-30 kg/m2), and 55 morbidly obese (BMI>30 kg/m2) patients were compared with 238 normal-weight recipients (BMI=20-27 kg/m2). We evaluated the influence of pretransplant BMI on morbidity and mortality after cardiac transplantation. Kaplan-Meier survival distribution and Cox proportional hazards model were used for statistical analyses. Morbidly obese as well as cachectic recipients demonstrated nearly twice the 5-year mortality of normal-weight or overweight recipients (53% vs. 27%, respectively, P=0.001). An increase in mortality was seen at 30 days for morbidly obese and cachectic recipients (12.7% and 17.7%, respectively) versus a 30-day mortality rate of 7.6% in normal-weight recipients. Morbidly obese recipients experienced a shorter time to high-grade acute rejection (P=0.004) as well as an increased annual high-grade rejection frequency when compared with normal-weight recipients (P=0.001). By multivariable analysis, the incidence of transplant-related coronary artery disease (TCAD) was not increased in morbidly obese patients but cachectic patients had a significantly lower incidence of TCAD (P=0.05). Cachectic patients receiving oversized donor hearts had a significantly higher postoperative mortality (P=0.02). The risks of cardiac transplantation are increased in both morbidly obese and cachectic patients compared with normal-weight recipients. However, the results of cardiac transplantation in overweight patients is comparable to that in normal-weight patients. Recipient size should be kept in mind while selecting patients and the use of oversized donors in cachectic recipients should be avoided.

  4. Childhood Obesity: A Review of Increased Risk for Physical and Psychological Co-morbidities

    Pulgarón, Elizabeth R.

    2013-01-01

    Background Worldwide estimates of childhood overweight/obesity are as high as 43 million and rates continue to increase each year. Researchers have taken interest in the childhood obesity epidemic and the impact of this condition across health domains. The consequences of childhood and adolescent obesity are extensive, including both medical and psychosocial comorbidities. Objective The purpose of this review was to consolidate and highlight the recent literature on the comorbidities associated with childhood obesity, both nationally and internationally. Methods PubMed and PsychINFO searches were conducted on childhood obesity and co-morbidities. Results The initial search of the terms “obesity” and “comorbidity” yielded over 5000 published articles. Limits were set to include studies on children and adolescents that were published in peer-reviewed journals from 2002 to 2012. These limits narrowed the search to 938. Review of those articles resulted in 79 that are included in this review. The major medical comorbidities associated with childhood obesity in the current literature are metabolic risk factors, asthma, and dental health issues. Major psychological comorbidities include internalizing and externalizing disorders, ADHD, and sleep problems. Conclusions The high prevalence rates of childhood obesity have resulted in extensive research in this area. Limitations to the current childhood obesity literature include differential definitions of weight status and cut off levels for metabolic risk factors across studies. Additionally, some results are based on self-report of diagnoses rather than chart reviews or physician diagnosis. Even so, there is substantial support for metabolic risk factors, internalizing disorders, ADHD, and decreased health related quality of life as comorbidities to obesity in childhood. Additional investigations on other diseases and conditions that may be associated with childhood obesity are warranted and intervention research

    Obesity and insulin resistance are associated with altered brain glucose metabolism. Here, we studied brain glucose metabolism in 22 morbidly obese patients before and 6 months after bariatric surgery. Seven healthy subjects served as control subjects. Brain glucose metabolism was measured twice per imaging session: with and without insulin stimulation (hyperinsulinemic-euglycemic clamp) using [18F]fluorodeoxyglucose scanning. We found that during fasting, brain glucose metabolism was not different between groups. However, the hyperinsulinemic clamp increased brain glucose metabolism in a widespread manner in the obese but not control subjects, and brain glucose metabolism was significantly higher during clamp in obese than in control subjects. After follow-up, 6 months postoperatively, the increase in glucose metabolism was no longer observed, and this attenuation was coupled with improved peripheral insulin sensitivity after weight loss. We conclude that obesity is associated with increased insulin-stimulated glucose metabolism in the brain and that this abnormality can be reversed by bariatric surgery.

  6. Morbidity of severe obesity.

    Kral, J G

    2001-10-01

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

  7. Pain Catastrophizing in Borderline Morbidly Obese and Morbidly Obese Individuals with Osteoarthritic Knee Pain

    2008-01-01

    Full Text Available OBJECTIVE: There is limited information about how morbidly obese osteoarthritis (OA patients cope with the pain they experience. Pain catastrophizing is an important predictor of pain and adjustment in persons with persistent pain. This may be particularly relevant in the morbidly obese (body mass index [BMI] of 40 kg/m2 or greater OA population at risk for increased pain. The present study first examined whether borderline morbidly obese and morbidly obese OA patients report higher levels of pain catastrophizing than a sample of OA patients in the overweight and obese category (BMI between 25 kg/m2 and 34 kg/m2. Next, it examined how pain catastrophizing is related to important indexes of pain and adjustment in borderline morbidly obese and morbidly obese OA patients.

  8. Maternal morbid obesity and obstetric outcomes.

    Farah, Nadine

    2012-02-01

    OBJECTIVE: The purpose of this retrospective cohort study was to review pregnancy outcomes in morbidly obese women who delivered a baby weighing 500 g or more in a large tertiary referral university hospital in Europe. METHODS: Morbid obesity was defined as a BMI > or =40.0 kg\\/m2 (WHO). Only women whose BMI was calculated at their first antenatal visit were included. The obstetric out-comes were obtained from the hospital\\'s computerised database. RESULTS: The incidence of morbid obesity was 0.6% in 5,824 women. Morbidly obese women were older and were more likely to be multigravidas than women with a normal BMI. The pregnancy was complicated by hypertension in 35.8% and diabetes mellitus in 20.0% of women. Obstetric interventions were high, with an induction rate of 42.1% and a caesarean section rate of 45.3%. CONCLUSIONS: Our findings show that maternal morbid obesity is associated with an alarmingly high incidence of medical complications and an increased level of obstetric interventions. Consideration should be given to developing specialised antenatal services for morbidly obese women. The results also highlight the need to evaluate the effectiveness of prepregnancy interventions in morbidly obese women.

    Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy. A retrospective review was performed of all patients undergoing laparoscopic colectomy between 1996 and 2013. Patients were classified according to their BMI as obese (BMI 30.0-39.9), morbidly obese (BMI 40.0-49.9), and super obese (BMI >50). Main outcome measures included conversion rate, operative time, estimated blood loss, post-operative complications, and length of stay. There were 923 patients who met inclusion criteria. Overall, 604 (65.4%), 257 (27.9%), and 62 (6.7%) were classified as obese (O), morbidly obese (MO), and super obese (SO), respectively. Clinicopathologic characteristics were similar among the three groups. The SO group had significantly higher conversion rates (17.7 vs. 7 vs. 4.8%; P = 0.031), longer average hospital stays (7.1 days vs. 4.9 vs. 3.4; P = 0.001), higher morbidity (40.3 vs. 16.3 vs. 12.4%; P = 0.001), and longer operative times (206 min vs. 184 vs. 163; P = 0.04) compared to the MO and O groups, respectively. The anastomotic leak rate in the SO (4.8%; P = 0.027) and MO males (4.1%; P = 0.033) was significantly higher than MO females (2.2%) and all obese patients (1.8%). Increasing severity of obesity is associated with worse perioperative outcomes following laparoscopic colectomy.

    The number of adolescent bariatric surgeries (ABS) performed from 2003 to 2009 has been stable despite reports of an increase in adolescent morbid obesity. We sought to determine the trend in national ABS volume and the changes in obesity-associated co-morbidities (OACM) from 2004 to 2011. The Healthcare Cost and Utilization Project National Inpatient Sample database. The National Inpatient Sample database was queried for adolescents undergoing Roux-en-Y gastric bypass, adjustable gastric banding, or sleeve gastrectomy from 2004 to 2011. Twelve OACM categories were created by ICD-9 code. From 2004 to 2011, an estimated 968 ABS cases per year were performed with no significant change in yearly volumes. There was a significant decrease in the annual volume of Roux-en-Y gastric bypasses (85.7%-54.4%, Padolescent increased significantly, from 1.44±1.3 in 2004-2005 to 1.85±1.5 in 2010-2011 (Padolescent bariatric surgical evaluation and treatment.

    Postmortem studies have demonstrated that morbidly obese subjects, surprisingly, have less coronary atherosclerosis than obese subjects. However, the reasons for this apparent protection from atherosclerosis are not yet clear. Thromboxane A2, a marker of platelet activation, is greater in obese subjects than in lean subjects, and this might be a clue to their increased cardiovascular risk. However, data on thromboxane A2 in morbidly obese subjects are lacking; therefore, we hypothesized that lower levels of thromboxane A2 in morbidly obese subjects might play a role in their lower atherothrombotic burden. We measured the serum levels of thromboxane B2 (TxB2), a stable metabolite of thromboxane A2, high-sensitivity C-reactive protein (hs-CRP) and leptin in 17 lean subjects (body mass index [BMI] 22.9 ± 1.6 kg/m(2)), 25 obese subjects (BMI 32.6 ± 2.4 kg/m(2)), and 23 morbidly obese subjects (BMI 48.6 ± 7.1 kg/m(2)), without insulin resistance, diabetes, or overt cardiovascular disease. The serum TxB2 levels were lower in the lean subjects than in the obese subjects (p = 0.046) and in the morbidly obese subjects than in the lean and obese subjects (p = 0.015 and p lean subjects (hs-CRP, p lean subjects (p lean subjects, suggesting that reduced platelet activation could play a role in the paradoxical protection of morbidly obese subjects from atherosclerosis, despite the greater levels of leptin.

  14. Increased Circulating Levels of Alpha-Ketoglutarate in Morbidly Obese Women with Non-Alcoholic Fatty Liver Disease.

    Gemma Aragonès

    Full Text Available Non-alcoholic fatty liver disease (NAFLD causes a wide spectrum of liver damage, ranging from simple steatosis to cirrhosis. However, simple steatosis (SS and steatohepatitis (NASH cannot yet be distinguished by clinical or laboratory features. The aim of this study was to assess the relationship between alpha-ketoglutarate and the degrees of NAFLD in morbidly obese patients.We used a gas chromatography-quadruple time-of-flight-mass spectrometry analysis to quantify alpha-ketoglutarate in serum from normal-weight subjects (n = 30 and morbidly obese women (n = 97 with or without NAFLD.We found that serum levels of alpha-ketoglutarate were significantly higher in morbidly obese women than in normal-weight women. We showed that circulating levels of alpha-ketoglutarate were lower in lean controls and morbidly obese patients without NAFLD. We also found that alpha-ketoglutarate serum levels were higher in both SS and NASH than in normal liver of morbidly obese patients. However, there was no difference between SS and NASH. Moreover, we observed that circulating levels of alpha-ketoglutarate were associated with glucose metabolism parameters, lipid profile, hepatic enzymes and steatosis degree. In addition, diagnostic performance of alpha-ketoglutarate has been analyzed in NAFLD patients. The AUROC curves from patients with liver steatosis exhibited an acceptable clinical utility. Finally, we showed that the combination of biomarkers (AST, ALT and alpha-ketoglutarate had the highest accuracy in diagnosing liver steatosis.These findings suggest that alpha-ketoglutarate can determine the presence of non-alcoholic fatty liver in morbidly obese patients but it is not valid a biomarker for NASH.

Studies of such factors are important to develop targeted interventions to improve health. The main purpose of this study is to explore sense of coherence (SOC in a sample of persons with morbid obesity before and after attending a patient education course and to explore the association between SOC and sociodemographic and other personal factors. Methods: In this longitudinal purposely sampled study, the participants completed questionnaires on the first day of the course and 12 months after course completion. Sixty-eight participants had valid scores on the selected variables at follow-up: SOC, self-esteem, and self-efficacy. Relationships were assessed with correlation analyses and paired and independent samples t-tests and predictors with linear regression analyses. Results: From baseline to follow-up, the total SOC score and the subdimension scores comprehensibility, manageability, and meaningfulness all increased significantly. At both time points, the SOC scores were low compared to the general population but similar to scores in other chronically ill. At baseline, a multivariate analysis showed that older age, having paid work, and higher self-esteem were directly related to higher total SOC score after controlling for other sociodemographic factors and the participants' level of self-efficacy. Multivariate analyses of the relationship between baseline predictors of SOC at 12-month follow-up, controlling for baseline SOC scores or sociodemographic or personal factors, revealed that none of these variables independently predicted SOC scores at follow-up.

    Morbid obesity (body mass index (BMI) > or =40 kg/m2) is associated with substantially increased morbidity and mortality from chronic health conditions and with poorer health-related quality of life; however, less is known about the impact of morbid obesity on healthcare expenditures. To examine the impact of morbid obesity on healthcare expenditures using a nationally representative sample of US adults. We performed a cross-sectional analysis of 16 262 adults from the 2000 Medical Expenditure Panel Survey, a nationally representative survey of the noninstitutionalized civilian population of the United States. Per capita healthcare expenditures were calculated for National Institutes of Health BMI categories, based on self-reported height and weight, using a two-part, multivariable model adjusted for age, gender, race, income, education level, type of health insurance, marital status, and smoking status. Odds of incurring any healthcare expenditure and per capita healthcare expenditures associated with morbid obesity in 2000. When compared with normal-weight adults, the odds of incurring any healthcare expenditure in 2000 were two-fold greater among adults with morbid obesity. Per capita healthcare expenditures for morbidly obese adults were 81% (95% confidence interval (CI): 48-121%) greater than normal-weight adults, 65% (95% CI: 37-110%) greater than overweight adults, and 47% (95% CI: 11-96%) greater than adults with class I obesity. Excess costs among morbidly obese adults resulted from greater expenditures for office-based visits, outpatient hospital care, in-patient care, and prescription drugs. Aggregate US healthcare expenditures associated with excess body weight among morbidly obese US adults exceeded $11 billion in 2000. The economic burden of morbid obesity among US adults is substantial. Further research is needed to identify interventions to reduce the incidence and prevalence of morbid obesity and improve the health and economic outcomes of morbidly

    Full Text Available Obesity is currently one of the major public health problems, in both developed and developing countries. Obesity is a risk factor for metabolic syndrome. Increasing rates of childhood obesity and more sedentary lifestyles has led to an age shift in metabolic syndrome which now occurs at an earlier age. Thus, the present study was conducted to get an idea about the occurrence of obesity among adolescent school children, risk factors associated with the condition and the related morbidity among them. MATERIALS AND METHODS: A cross-sectional descriptive study carried out in two higher secondary government girl schools with the help of a pre- designed and pre-tested questionnaire. RESULTS: Out of 245 students 16.73% were overweight and 6.54% were obese. Among overweight students, 59.65% exercised less than 4 hours a week, 61.4% watched TV ≥ 4 hours per week, 87.72% consumed junk food ≥ 4 days per week and 45.61% skipped meals. Puberty related menstrual irregularities, hypothyroidism, acne and stria were more commonly found in overweight students CONCLUSION: The rapidly increasing prevalence of obesity accompanied by unhealthy lifestyle habits among adolescents is one of the most challenging dilemmas of public health importance.

  1. Laparoscopic surgery for morbid obesity.

    Hallerbäck, B; Glise, H; Johansson, B; Johnson, E

    1998-01-01

    Morbid obesity, defined as a body mass index (BMI), i.e. weight (kg)/height (m2) over 36 for males and 38 for females, is a common condition and a threat for health, life and individual well being. Hitherto, surgery is the only effective treatment for weight reduction. Surgical methods can be malabsorptive, reducing the patients ability to absorb nutrients, or restrictive, reducing the capacity of food intake. Exclusively malabsorptive methods have been abandoned due to severe side effects. Restrictive methods, gastroplasties, reduces the compliance capacity of the stomach. Two types are performed laparoscopically, the vertical banded gastroplasty and the adjustable gastric banding. The proximal gastric by pass is also performed laparoscopically and is a combination of a restrictive proximal gastroplasty and a malabsorptive Roux-en-Y gastro-jejunal anastomosis. With laparoscopic adjustable gastric banding mean BMI was reduced from 41 kg/m2 to 33 kg/m2 (n = 43) after one year. Two years after surgery mean BMI was 30 kg/m2 (n = 16). The different operative techniques are further discussed in this paper.

  2. Surgery for Gastroesophageal Reflux Disease in the Morbidly Obese Patient.

    Duke, Meredith C; Farrell, Timothy M

    2017-01-01

    The prevalence of gastroesophageal reflux disease (GERD) has mirrored the increase in obesity, and GERD is now recognized as an obesity-related comorbidity. There is growing evidence that obesity, specifically central obesity, is associated with the complications of chronic reflux, including erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. While fundoplication is effective in creating a competent gastroesophageal junction and controlling reflux in most patients, it is less effective in morbidly obese patients. In these patients a bariatric operation has the ability to correct both the obesity and the abnormal reflux. The Roux-en-Y gastric bypass is the preferred procedure.

    Interventions to increase physical activity in pregnancy are challenging for morbidly obese women. Targeting sedentary behaviours may be a suitable alternative to increase energy expenditure. We aimed to determine total energy expenditure, and energy expended in sedentary activities in morbidly obese and lean pregnant women. We administered the Pregnancy Physical Activity Questionnaire PPAQ (non-objective) and the Actical accelerometer (objective) to morbidly obese (BMI≥40kg/m²) and lean (BMI≤25Kg/M²) pregnant women recruited in early (lean pregnant women. No differences were observed in the proportion of energy expended sedentary between lean and morbidly obese pregnant women. The greater total energy expenditure in morbidly obese pregnant women was corroborated by Actical accelerometer in early (n=14 per group, obese 1167.7 (313.6) Kcal; lean 781.1 (210.1) Kcal, plean 893.7 (175.9) Kcal, plean pregnant. Further studies are needed to determine whether sedentary behaviours are a suitable target for intervention in morbidly obese pregnancy. This article is protected by copyright. All rights reserved.

  4. Morbidity, including fatal morbidity, throughout life in men entering adult life as obese.

    Esther Zimmermann

    Full Text Available BACKGROUND: The association between obesity in adults and excess morbidity and mortality is well established, but the health impact throughout adult life of being obese in early adulthood needs elucidation. We investigated somatic morbidity, including fatal morbidity, throughout adulthood in men starting adult life as obese. METHODS: Among 362,200 Danish young men, examined for military service between 1943 and 1977, all obese (defined as BMI≥31.0 kg/m(2, and, as controls, a random 1% sample of the others was identified. In the age range of 18-25 years, there were 1,862 obese, which encompass the men above the 99.5 percentile, and 3,476 controls. Information on morbidity was obtained via national registers. Cox regression models were used to estimate the relative morbidity assessed as first incidence of disease, occurrence of disease in the year preceding death and prevalent disease at time of death. RESULTS: From age 18 through 80 years the obese had an increased risk of becoming diseased by or die from a broad range of diseases. Generally, the incidence of first event, occurrence in the year prior to death, and prevalence at time of death showed the same pattern. As an example, the relative hazard of type 2 diabetes was constant throughout life at 4.9 (95% confidence intervals [CI]: 4.1-5.9, 5.2 (95% CI: 3.6-7.5, and 6.8 (95% CI: 4.6-10.1, respectively. CONCLUSIONS: Our findings strongly support the continued need to avoid beginning adult life as obese, as obese young men experience an increased morbidity, including fatal morbidity, from many diseases throughout life.

    Plasma fibronectin concentrations and liver morphology were investigated in 45 morbidly obese subjects (median overweight 88%) and in 42 normal weight controls, matched for sex and age. A significantly (P less than 0.01) raised plasma fibronectin concentration (median 464 mg/l, range 276-862 mg...... in their liver biopsies (r = 0.33, P less than 0.05). Significantly (P less than 0.05) elevated plasma fibronectin concentrations even in obese subjects without hepatic fatty change indicate that liver fat accumulation is no prerequisite of the obesity-related elevation of plasma fibronectin. Raised plasma...

  6. Epidemiology, morbidity, and treatment of overweight and obesity.

    Aronne, L J

    2001-01-01

    Although still considered more of a cosmetic problem by both the general public and some areas of the medical community, overweight and obesity have reached epidemic proportions worldwide. Overweight and obesity have not only a significant psychological impact but also result in an increased risk for development of numerous chronic and sometimes fatal diseases. The morbidity from obesity-associated disorders increases with higher body mass index and begins within the normal weight range. The costs (direct and indirect) associated with treating obesity and its comorbid conditions are notable and increasing. Obesity rates in patients with schizophrenia are at least as high, if not higher, than in the general population. This article reviews the epidemiology and burden of obesity and its associated comorbid disorders. The guidelines from the National Heart, Lung, and Blood Institute of the National Institutes of Health for diagnosing and treating obesity are also discussed.

  7. Orthopedic trauma surgery in the morbidly obese patient.

    Bozzio, Anthony E; Gala, Raj J; Villasenor, Mario A; Hao, Jiandon; Mauffrey, Cyril

    2014-05-01

    The treatment of morbidly obese patients in orthopedic trauma differs in many ways compared to injured patients with normal body mass indices. This paper highlights key differences and ways to overcome obstacles. We present specific tips, as well as considerations for initial planning, positioning for surgery, intra-operative strategies, and a discussion on both anesthesia and imaging. Several treatment strategies have been shown to have better results in morbidly obese patients. Pre-operative planning is necessary for minimizing risk to the patient. The prevalence of morbid obesity has increased in the USA in the past quarter century. Treatment for orthopedic injuries in morbidly obese patients requires a multidisciplinary approach that addresses not only their orthopedic injuries, but also medical co-morbidities. A team of medicine doctors, anesthesiologists, X-ray technicians, physical and occupational therapists, respiratory therapists, and social workers is needed in addition to the orthopedic surgeon. Modifications in both pre-operative planning and intra-operative strategies may be necessary in order to accommodate the patient. This paper presents numerous technical tips that can aid in providing stable fixation for fractures, as well as addressing peri-operative issues specific to the morbidly obese.

  8. Are there risk factors that increase the rate of staple line leakage in patients undergoing primary sleeve gastrectomy for morbid obesity?

    Benedix, Frank; Benedix, Diana D; Knoll, Christian; Weiner, Rudolf; Bruns, Christiane; Manger, Thomas; Stroh, Christine

    2014-10-01

    Laparoscopic sleeve gastrectomy (LSG) is currently being performed with increasing frequency worldwide. It offers an excellent weight loss and resolution of comorbidities in the short term with a very low incidence of complications. However, the ever present risk of a staple line leak is still a major concern. Since 2005, data from obese patients that undergo bariatric procedures in Germany are prospectively registered in an online database and analyzed at the Institute of Quality Assurance in Surgical Medicine. For the current analysis, all patients that had undergone primary sleeve gastrectomy for morbid obesity within a 7-year period were considered. Using the GBSR, data from 5.400 LSGs were considered for analysis. Staple line leak rate decreased during the study period from 6.5 to 1.4 %. Male gender, higher BMI, concomitant sleep apnea, conversion to laparotomy, longer operation time, use of both buttresses and oversewing, and the occurrence of intraoperative complications were associated with a significantly higher leakage rate. On multivariate analysis, operation time and year of procedure only had a significant impact on staple line leak rate. The results of the current study demonstrated that there are factors that increase the risk of a leakage which would enable surgeons to define risk groups, to more carefully select patients, and to offer a closer follow-up during the postoperative course with early recognition and adequate treatment. All future efforts should be focused on a further reduction of serious complications to make the LSG a widely accepted and safer procedure.

    To describe gonadal dysfunction and evaluate polycystic ovary syndrome (PCOS) and its association with metabolic syndrome (MeS) among girls in a morbidly obese adolescent population. In a cross-sectional study of 174 girls, height, weight, waist circumference, Tanner stage, reproductive hormones, carbohydrate and lipid markers, drug use, and menstrual history were obtained at baseline. Exclusion criteria were menarcheal age PCOS or MeS classification. University medical center outpatient clinic. Ninety-eight girls ages 13-19.6 years, Tanner 5, average body mass index of 46.6 kg/m(2), menarche at 11.4 years, and average menarcheal age of 5 years. None. Polycystic ovary syndrome and MeS. Ninety-eight girls were divided into four groups: PCOS by National Institutes of Health criteria (PCOSN, n = 24), irregular menses only (n = 25), elevated T (≥55 ng/dL) only (n = 6), and obese controls (n = 43). Metabolic syndrome by modified Cook criteria affected 32 girls or 33% overall: 6 of 24 PCOSN, 7 of 25 irregular menses only, 4 of 6 elevated T only, and 15 of 43 obese controls. Polycystic ovary syndrome by National Institutes of Health criteria and its individual components were not associated with MeS after adjusting for body mass index. Unlike obese adults, PCOSN and its individual components were not associated with MeS in the untreated morbidly obese adolescent population.

    2016-03-01

    Olfactory abilities of the patients are known to be altered by eating and metabolic disorders, including obesity. There are only a number of studies investigating the effect of obesity on olfaction, and there is limited data on the changes in olfactory abilities of morbidly obese patients after surgical treatment. Here we investigated the changes in olfactory abilities of 54 morbidly obese patients (M/F, 22/32; age range 19-57 years; body mass index (BMI) range 30.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. A laparoscopic sleeve gastrectomy was performed by the same surgeon using five-port technique. Olfactory abilities were tested preoperatively and 1, 3, and 6 months after the surgery using a standardized Sniffin' Sticks Extended Test kit. Analyses of variance indicated statistically significant improvement in T, D, and I scores of morbidly obese patients within time factors (preoperative vs. 1, 3, and 6 months; 1 vs. 3 and 6 months; and 3 vs. 6 months; p < 0.001 for all). There was a statistically significant improvement in overall TDI scores with an increase from 25 to 41 during the 6 months follow-up period (p < 0.001 for all). Here, for the first time in literature, we were able to show the significant improvement in olfactory abilities of morbidly obese patients after laparoscopic sleeve gastrectomy.

  13. Interleukin-17A Gene Expression in Morbidly Obese Women

    Fernando Zapata-Gonzalez

    2015-07-01

    Full Text Available Data from recent studies conducted in rodent models and humans suggest that interleukin-17A (IL-17A plays a role in the induction of inflammation in adipose tissue during obesity. The aim of this study was to assess the gene expression of IL-17A in adipose tissue of morbidly obese patients. We used RT-PCR to evaluate the expression of IL-17A and several adipo/cytokines in the visceral adipose tissue (VAT and subcutaneous adipose tissue (SAT of 10 normal-weight control women (BMI < 25 kg/m2 and 30 morbidly obese women (MO, BMI > 40 kg/m2. We measured serum levels of IL-17A and adipo/cytokines in MO and normal weight women. IL-17A expression was significantly higher in VAT than in SAT in MO patients (p = 0.0127. It was very low in normal-weight controls in both VAT and SAT tissues. We found positive correlations between IL-17A and IL-6, lipocalin-2 and resistin in VAT of MO patients. The circulating level of IL-17A was higher in the normal-weight group than the MO patients (p = 0.032, and it was significantly related to adiponectin and TNFRII levels. In conclusion, IL-17A expression in VAT is increased in morbidly obese women, which suggests a link between obesity and innate immunity in low-grade chronic inflammation in morbidly obese women.

  14. Childhood obesity as a predictor of morbidity in adulthood: a systematic review and meta-analysis.

    Llewellyn, A; Simmonds, M; Owen, C G; Woolacott, N

    2016-01-01

    Obese children are at higher risk of being obese as adults, and adult obesity is associated with an increased risk of morbidity. This systematic review and meta-analysis investigates the ability of childhood body mass index (BMI) to predict obesity-related morbidities in adulthood. Thirty-seven studies were included. High childhood BMI was associated with an increased incidence of adult diabetes (OR 1.70; 95% CI 1.30-2.22), coronary heart disease (CHD) (OR 1.20; 95% CI 1.10-1.31) and a range of cancers, but not stroke or breast cancer. The accuracy of childhood BMI when predicting any adult morbidity was low. Only 31% of future diabetes and 22% of future hypertension and CHD occurred in children aged 12 or over classified as being overweight or obese. Only 20% of all adult cancers occurred in children classified as being overweight or obese. Childhood obesity is associated with moderately increased risks of adult obesity-related morbidity, but the increase in risk is not large enough for childhood BMI to be a good predictor of the incidence of adult morbidities. This is because the majority of adult obesity-related morbidity occurs in adults who were of healthy weight in childhood. Therefore, targeting obesity reduction solely at obese or overweight children may not substantially reduce the overall burden of obesity-related disease in adulthood. © 2015 World Obesity.

  15. What is the optimal minimally invasive surgical procedure for endometrial cancer staging in the obese and morbidly obese woman?

    Gehrig, Paola A; Cantrell, Leigh A; Shafer, Aaron; Abaid, Lisa N; Mendivil, Alberto; Boggess, John F

    2008-10-01

    Thirty-three percent of U.S. women are either obese or morbidly obese. This is associated with an increased risk of death from all causes and is also associated with an increased risk of endometrial carcinoma. We sought to compare minimally invasive surgical techniques for staging the obese and morbidly obese woman with endometrial cancer. Consecutive robotic endometrial cancer staging procedures were collected from 2005-2007 and were compared to consecutive laparoscopic cases (2000-2004). Demographics including age, weight, body mass index (BMI), operative time, estimated blood loss, lymph node retrieval, hospital stay and complications were collected and compared. During the study period, there were 36 obese and 13 morbidly obese women who underwent surgery with the DaVinci robotic system and 25 obese and 7 morbidly obese women who underwent traditional laparoscopy. For both the obese and morbidly obese patient, robotic surgery was associated with shorter operative time (p=0.0004), less blood loss (ptool for the comprehensive surgical staging of the obese and morbidly obese woman with endometrial cancer. As this patient population is at increased risk of death from all causes, including post-operative complications, all efforts should be made to improve their outcomes and minimally invasive surgery provides a useful platform by which this can occur.

    2016-10-01

    Objective To estimate the association between maternal super obesity (body mass index [BMI] ≥ 50 kg/m(2)) and neonatal morbidity among neonates born via cesarean delivery (CD). Methods Retrospective cohort of singleton neonates delivered via CD ≥ 37 weeks in the Maternal-Fetal Medicine Unit Cesarean Registry. Maternal BMI at delivery was stratified as 18.5 to 29.9 kg/m(2), 30 to 39.9 kg/m(2), 40 to 49.9 kg/m(2), and ≥ 50 kg/m(2). Primary outcomes included acute (5-minute Apgar score neonatal injury, and/or transient tachypnea of the newborn) and severe (grade 3 or 4 intraventricular hemorrhage, necrotizing enterocolitis, seizure, respiratory distress syndrome, hypoxic ischemic encephalopathy, meconium aspiration, ventilator support ≥ 2 days, sepsis and/or neonatal death) neonatal morbidity. Odds of neonatal morbidity were estimated for each BMI category adjusting for clinical and operative characteristics. Results Of 41,262 maternal-neonatal dyads, 36% of women were nonobese, 49% had BMI of 30 to 39.9 kg/m(2), 12% had BMI of 40 to 49.9 kg/m(2), and 3% were super obese. Compared with nonobese women, super obese women had twofold odds of acute (5 vs. 10%; adjusted odds ratio [aOR]: 1.81, 95% confidence interval [CI]: 1.59-2.73) and severe (3 vs. 6%; aOR: 2.08; 95% CI: 1.59-2.73) neonatal morbidity. Conclusion Among term infants delivered via CD, maternal super obesity is associated with increased risk of neonatal morbidity. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

  17. Children With Morbid Obesity Benefit Equally as Children With Overweight and Obesity From an Ongoing Care Program.

    Rijks, J M; Plat, J; Mensink, R P; Dorenbos, E; Buurman, W A; Vreugdenhil, A C E

    2015-09-01

    Despite stabilization of childhood overweight and obesity prevalence, there is a shift toward more severe degrees of obesity, which results in an increasing prevalence of children with morbid obesity. Prior studies demonstrated that lifestyle modification without ongoing treatment has only a modest and not sustainable effect in children with morbid obesity. This suggests that a chronic care model is necessary for long-term effects on weight management and health. This study aimed to evaluate the effect of an ongoing lifestyle intervention in children with morbid obesity in comparison with children with overweight and obesity. This was a nonrandomized prospective intervention study with 12- and 24-month followup at the Centre for Overweight Adolescent and Children's Healthcare. Children and adolescents (n = 100 females and 72 males) with overweight, obesity, or morbid obesity were given long-term, outpatient, tailored lifestyle intervention. Body mass index (BMI) z score was measured. In children with morbid obesity, 12- and 24-month interventions resulted in a decrease of BMI z score of -0.13 ± 0.25 (P = .001) and -0.23 ± 0.32 (P = .01) respectively, whereas weight status category improved to obese in 21% and 25% of the children. Cardiovascular risk parameters including serum total cholesterol, low-density lipoprotein cholesterol, glycosylated hemoglobin (HbA1c), and diastolic blood pressure significantly improved after 1-year intervention in the complete group. Most important, BMI z score as well as cardiovascular risk parameters improved to a similar degree in children with overweight, obesity, and morbid obesity. Children with overweight, obesity, and morbid obesity benefit equally from an ongoing, outpatient, tailored lifestyle intervention, and demonstrate significant weight loss and improvement of cardiovascular risk parameters.

    Morbid obesity is directly related to deterioration in cardiorespiratory capacity, including changes in cardiovascular autonomic modulation. This study aimed to assess the cardiovascular autonomic function in morbidly obese individuals. Cross-sectional study, including two groups of participants: Group I, composed by 50 morbidly obese subjects, and Group II, composed by 30 nonobese subjects. The autonomic function was assessed by heart rate variability in the time domain (standard deviation of all normal RR intervals [SDNN]; standard deviation of the normal R-R intervals [SDNN]; square root of the mean squared differences of successive R-R intervals [RMSSD]; and the percentage of interval differences of successive R-R intervals greater than 50 milliseconds [pNN50] than the adjacent interval), and in the frequency domain (high frequency [HF]; low frequency [LF]: integration of power spectral density function in high frequency and low frequency ranges respectively). Between-group comparisons were performed by the Student’s t-test, with a level of significance of 5%. Obese subjects had lower values of SDNN (40.0 ± 18.0 ms vs. 70.0 ± 27.8 ms; p = 0.0004), RMSSD (23.7 ± 13.0 ms vs. 40.3 ± 22.4 ms; p = 0.0030), pNN50 (14.8 ± 10.4 % vs. 25.9 ± 7.2%; p = 0.0061) and HF (30.0 ± 17.5 Hz vs. 51.7 ± 25.5 Hz; p = 0.0023) than controls. Mean LF/HF ratio was higher in Group I (5.0 ± 2.8 vs. 1.0 ± 0.9; p = 0.0189), indicating changes in the sympathovagal balance. No statistical difference in LF was observed between Group I and Group II (50.1 ± 30.2 Hz vs. 40.9 ± 23.9 Hz; p = 0.9013). morbidly obese individuals have increased sympathetic activity and reduced parasympathetic activity, featuring cardiovascular autonomic dysfunction.

    Weight loss and psychosocial events have been compared between low calorie conventional diet (n = 11) or following obesity surgery (n = 17). Interviews were >/= 9 months following initiation of treatment. After surgery significantly less hunger was experienced (surgery 76% [13/17] vs diet 18% [2/11] p employed (surgery 76% [13/17] vs diet 18% [2/11) p appearance improvements (surgery 94% [15/16] vs diet 50% [5/10] p Physical activity improved (surgery 73% [11/15] vs diet 18% [2/11] p Physical activity increases, and satisfaction with weight loss method is greater, after surgery. Employment is greater (probably self selection) in the post-surgical group. We found that comparing >/= 9 months following surgery or beginning a conventional diet, the morbidly obese have a more positive response to surgery.

  3. Radiologic findings and weight loss following gastroplasty for morbid obesity

    Miskowiak, J.; Fleckenstein, P.; Andersen, B.

    Gastroplasty aimed at treatment of morbid obesity creates a small proximal pouch and a narrow stoma to the remainder of the stomach. In 11 consecutive obese patients subjected to gastroplasty radiologic examinations of the stomach were performed before operation and one week, 3 and 12 months postoperatively. All stomachs were normal before operation. A significant decrease in pouch area and increase in stoma diameter were registered over the observation period. There were no statistically significant correlations between postoperative weight loss and stoma diameter or pouch area. Nor was retention in the pouch one week after gastroplasty related to weight loss. Radiographic evidence of gastroesophageal reflux was present in only one patient. The described method of follow-up is evidently not suited to predict the outcome of gastroplasty.

    Hagen, Monika E.; Sedrak, Micheal; Wagner, Oliver J.; Jacobsen, Garth; Talamini, Mark; Horgan, Santiago

    2010-01-01

    Achalasia is a relatively rare medical condition that is classically not associated with obesity. The surgical treatment of a simultaneous occurrence of these two diseases requires careful consideration, and only a few reports can be found in the literature combining a Heller myotomy with gastric bypass, duodenal switch, or gastric banding. We report the case of a 69-year-old female patient with early achalasia and obesity who underwent simultaneous laparoscopic gastric sleeve resection and r...

  7. Tracheostomy in the Morbidly Obese: Difficulties and Challenges.

    Fattahi, Tirbod; Chafin, Christopher; Bunnell, Anthony

    2017-07-01

    This study evaluated the difficulties and challenges associated with open tracheostomy in the morbidly obese patient (body mass index [BMI] ≥30 kg/m 2 ). Forty patients met all the inclusion criteria. A retrospective chart review was performed to evaluate indications for tracheostomy, duration of intubation before tracheostomy, history of tracheostomy, duration of operative procedure, duration in the operating room, and all perioperative complications. Complications were classified as intraoperative (5%) and postoperative (17.5%). The average BMI was 46 kg/m 2 (range, 31.1 to 75.3 kg/m 2 ). The average duration of intubation before tracheostomy was 11 days. Ten patients (25%) previously underwent tracheostomy. The average operating time was 60 minutes (range, 20 to 95 minutes). The average total time in the operating room was 100 minutes (range, 45 to 146 minutes). This study shows that although open tracheostomy in the morbidly obese patient is increasing in demand, the procedure can be predictably performed albeit at a much longer duration and a higher perioperative complication rate compared with the traditional tracheostomy.

  9. Modifier 22 for acetabular fractures in morbidly obese patients: does it affect reimbursement?

    Bergin, Patrick F; Kneip, Christopher; Pierce, Christine; Hendrix, Stephen T; Porter, Scott E; Graves, Matthew L; Russell, George V

    2014-11-01

    Modifier 22 in the American Medical Association's Current Procedural Terminology (CPT®) book is a billing code for professional fees used to reflect an increased amount of skill, time, and work required to complete a procedure. There is little disagreement that using this code in the setting of surgery for acetabulum fractures in the obese patient is appropriate; however, to our knowledge, the degree to which payers value this additional level of complexity has not been determined. We asked whether (1) the use of Modifier 22 increased reimbursements in morbidly obese patients and (2) there was any difference between private insurance and governmental payer sources in treatment of Modifier 22. Over a 4-year period, we requested immediate adjudication with payers when using Modifier 22 for morbidly obese patients with acetabular fractures. We provided payers with evidence of the increased time and effort required in treating this population. Reimbursements were calculated for morbidly obese and nonmorbidly obese patients. Of the 346 patients we reviewed, 57 had additional CPT® codes or modifiers appended to their charges and were excluded, leaving 289 patients. Thirty (10%) were morbidly obese and were billed with Modifier 22. Fifty-three (18%) were insured by our largest private insurer and 69 (24%) by governmental programs (Medicare/Medicaid). Eight privately insured patients (15%) and seven governmentally insured patients (10%) were morbidly obese and were billed with Modifier 22. For our primary question, we compared reimbursement rates between patients with and without Modifier 22 for obesity within the 289 patients. We then performed the same comparison for the 53 privately insured patients and the 69 governmentally insured patients. Overall, there was no change in mean reimbursement when using Modifier 22 in morbidly obese patients, compared to nonmorbidly obese patients (USD 2126 versus USD 2149, p Level IV, economic and decision analyses.

    2011-02-01

    Full Text Available Abstract Background Obesity is associated with increased risk of cardiovascular disease. Arterial stiffness assessed by carotid femoral pulse wave velocity (PWV is an independent predictor of cardiovascular morbidity and mortality. We aimed to investigate how various measures of body composition affect arterial stiffness. Methods This is an analysis of cross-sectional baseline data from a controlled clinical trial addressing changes in arterial stiffness after either surgery or lifestyle intervention in a population of morbidly obese patients. High-fidelity applanation tonometry (Millar®, Sphygmocor® was used to measure pulse wave velocity (PWV. Carotid femoral PWV is a direct measure of arterial stiffness and is considered to be the gold standard method. The Inbody 720 Body Composition Analyzer was used for bioelectrical impedance analysis (BIA. Spearman's correlation, independent samples t-test, chi-square tests, Fisher's exact test and multiple linear regression analyses were used as statistical methods. Results A total of 133 patients (79 women, with a mean (SD age of 43 (11 years were included in the study. Men had a significantly higher prevalence of obesity related comorbidities and significantly higher PWV, 9.1 (2.0 m/s vs. 8.1 (1.8 m/s, p = 0.003, than women. In the female group, PWV was positively correlated with WC, WHtR, BMI and visceral fat area. In the male group, PWV was negatively correlated with BMI. Multiple linear regression analysis showed that increasing BMI, WC, WHtR, visceral fat area and fat mass were independently associated with higher PWV in women, but not in men, after adjustment for age, hypertension and type 2 diabetes. Conclusion Most measures of general and abdominal obesity were predictors of arterial stiffness in female morbidly obese patients. Trial registration ClinicalTrials.gov Identifier NCT00626964

    We describe the radiographic findings observed in a morbidly obese and diabetic patient with an intragastric air-filled balloon introduced as a therapeutic measure to reduce food intake. The balloon was associated with chronic gastric dilatation and had to be removed 3 months after insertion. However, together with diet and behavioural therapy, it proved effective in reducing body weight and ameliorating glycaemic control. Although rarely used, intragastric balloons for the treatment of morbid obesity are still encountered in radiological practice. Radiologists must be able to recognize them and to understand their complications. (orig.)

  16. Physical activity patterns in morbidly obese and normal-weight women.

    Kwon, Soyang; Mohammad, Jamal; Samuel, Isaac

    2011-01-01

    To compare physical activity patterns between morbidly obese and normal-weight women. Daily physical activity of 18 morbidly obese and 7 normal-weight women aged 30-58 years was measured for 2 days using the Intelligent Device for Energy Expenditure and Activity (IDEEA) device. The obese group spent about 2 hr/day less standing and 30 min/day less walking than did the normal-weight group. Time spent standing (standing time) was positively associated with time spent walking (walking time). Age- and walking time-adjusted standing time did not differ according to weight status. Promoting standing may be a strategy to increase walking.

  1. Cushing's Syndrome in a Morbidly Obese Patient Undergoing Evaluation before Bariatric Surgery

    Livia Borsoi

    2014-06-01

    Full Text Available Objective: Cushing's syndrome (CS is extremely rare in morbidly obese patients. To date, no occurrences in obese patients with BMI above 60 kg/m2 have been reported in the literature. Case Report: This case report describes a patient who was admitted to the ward of the Clinical Division of Endocrinology and Metabolism of the Medical University of Vienna in preparation for bariatric surgery. The patient was a 49-year-old female who showed morbid obesity (BMI 61.6 kg/m2, hypertension, and substituted hypothyroidism. Preoperative work-up revealed CS due to an adrenal adenoma. Therefore, the patient underwent unilateral adrenalectomy followed by bariatric surgery 6 months later. Conclusion: Since undiagnosed CS might result in severe perioperative complications in a population already at increased risk, this case report underlines the importance of careful endocrine evaluation of morbidly obese patients. After all, even rare endocrine causes should be excluded.

    2017-06-01

    Full Text Available Background. Due to the constant increase in the number of morbidly obese patients, an adequate tool for assessing the functioning and disability of these patients is being sought. The International Classification of Functioning, Disability and Health (IC F could be that tool. Objectives. The aim of this study is to examine the usefulness of the IC F scale in assessing the functioning of morbidly obese patients in two selected areas in reference to recognized scales. Material and methods . The study group included 76 patients with morbid obesity qualified for bariatric treatment. The ICF was applied to assess the function and limitations of each individual. Two domains of the IC F were selected: Body Functions and Structures and Activities and Participation. The usefulness of the IC F was compared to that of the Barthel and EPQ-R scales. Results . In morbidly obese patients, a correlation between motor functions and IC F and BMI, as well as age, was observed. A significant correlation was observed between BMI and psychomotor control, appropriateness and range of emotions experienced, age and amount of sleep, quality of sleep, memory retrieval and psychomotor functions. Women’s mental functions were significantly worse than those of men. In terms of interpersonal relations, a correlation between BMI and regulating behavior within interactions was observed. Conclusions . The IC F is a useful tool for the study and description of the functioning of patients with morbid obesity. The selected domains are described better than by the previously used Barthel scale. Women with morbid obesity tend to have more impaired mental functioning than morbidly obese men.

    The accumulation of visceral fat affects the metabolism of hormones and some nutrients, but these mechanisms remain unclear. To assess the influence of cortisol on the metabolism of zinc in morbidly obese women. Cross-sectional, case-control study involving 80 women aged between 20 and 59 years. The participants were divided into two groups: experimental (morbidly obese, n = 40) and control (normal weight, n = 40). Zinc concentrations were determined by atomic absorption spectroscopy and serum and urinary cortisol by chemiluminescence method. Zinc intake was significantly different between groups. Mean plasma zinc was lower in obese compared to control group. Mean values for erythrocyte zinc were 44.52 ± 7.84 µg/gHb and 40.17 ± 6.71 µg/gHb for obese and control groups, respectively. Urinary excretion of this mineral was higher in obese compared to control subjects (p cortisol were 9.58 ± 4.86 µg/dL for obese and 9.89 ± 5.61 µg/dL for control groups. Mean values for urinary cortisol were 163.00 ± 100.35 µg/dL and 109.71 ± 34.88 µg/dL for obese and control groups, respectively (p > 0.05). The correlation analysis between cortisol and zinc was not significant (p > 0.05). Obese patients have hypozincemia and high erythrocyte zinc levels. The correlation between zinc parameters and cortisol concentration showed no influence of this hormone on zinc metabolism.

  5. [Monogenic and syndromic symptoms of morbid obesity. Rare but important].

    Wiegand, S; Krude, H

    2015-02-01

    Monogenic and syndromic obesity are rare diseases with variable manifestation. Therefore diagnosis is difficult and often delayed. The purpose of this work was to develop a clinical diagnostic algorithm for earlier diagnosis. Available publications for clinical symptoms and molecular defects of monogenic and syndromic obesity cases were evaluated. Monogenic and syndromic obesity can be expected in cases with early manifestation before the age of 5 years and a BMI above 40 or above the 99th percentile. Syndromic cases are mostly associated with a low IQ and dwarfism. Monogenic cases are associated with additional endocrine defects. Measurement of serum leptin proves the treatable leptin deficiency. Sequencing of the melanocortin-4 receptor gene (MC4R) allows diagnosis of the most frequent monogenic form of obesity. Treatment with a melanocyte-stimulating hormone (MSH) analog can be expected in the future. Early treatment of children with Prader-Willi syndrome can prevent severe obesity. Because in some cases treatment is available, monogenic and syndromic obesity should be diagnosed early. Based on the disease symptoms, serum leptin, and MC4R sequencing, a diagnostic algorithm is proposed, which can be used to diagnose cases of morbid obesity.

  6. Ultrasound-Guided Thrombin Injection Is a Safe and Effective Treatment for Femoral Artery Pseudoaneurysm in the Morbidly Obese.

    Yoo, Taehwan; Starr, Jean E; Go, Michael R; Vaccaro, Patrick S; Satiani, Bhagwan; Haurani, Mounir J

    2017-08-01

    Ultrasound-guided thrombin injection (UGTI) is a well-established practice for the treatment of femoral artery pseudoaneurysm. This procedure is highly successful but dependent on appropriate pseudoaneurysm anatomy and adequate ultrasound visualization. Morbid obesity can present a significant technical challenge due to increased groin adiposity, resulting in poor visualization of critical structures needed to safely perform the procedure. We aim to evaluate the safety and efficacy of UGTI to treat femoral artery pseudoaneurysm in the morbidly obese. This is a retrospective cohort study in which all patients who underwent UGTI at The Ohio State University Ross Heart Hospital from 2009 to 2014 were analyzed for patient characteristics and stratified by body mass index (BMI). Patients with BMI ≥ 35 were considered morbidly obese and were compared to patients with a BMI injection. There were 41 nonmorbidly obese and 13 morbidly obese patients. Mean age was 64.5 years. The cohort was 44.4% male. There were 6 failures, of which 1 underwent successful repeat injection and 5 underwent open surgical repair. There was no statistically significant difference in failure between nonmorbidly obese and morbidly obese patients (9.8% vs 15.4%, P = .45). There were no embolic/thrombotic complications. Ultrasound-guided thrombin injection is a safe and effective therapy in the morbidly obese for the treatment of femoral artery pseudoaneurysm. In the hands of experienced sonographers and surgeons with adequate visualization of the pseudoaneurysm sac, UGTI should remain a standard therapy in the morbidly obese.

    It is estimated that there are nearly 40 million people with the human immunodeficiency virus (HIV) worldwide. Due to the advent of antiretroviral drugs, it has been observed increasing in obesity and metabolic rates among patients undergoing treatment. Thus, numerous surgical therapies for weight loss are proposed for continuous improvement in health of patients with HIV, being the vertical gastrectomy an option for intact intestinal transit. To evaluate the applicability of the vertical gastrectomy in patients with morbid obesity and HIV. Was conducted a systematic review of the literature, in the electronic databases Scopus, Pubmed, Cinahl, Scielo, Cochrane and Lilacs, from 1998 to 2015. MeSH headings used in data collection were "Gastrectomy" and "Morbid obesity" being combined with the descriptor "HIV". Were found 2148 articles in Scopus, 1234 in PubMed and 784 in Cinahl. The articles were analyzed by the Jadad Quality Scale, being reduced to 40 articles, subsequently reassessed using an elaborated form by the Critical Appraisal Skills Programme (CASP), reaching 12 articles in the end. It was found that vertical gastrectomy constitutes a safe and effective method, with low mortality and low rate of postoperative complications, being recommended as surgical technique in patients with obesity, HIV and comorbidities. Estima-se que haja quase 40 milhões de pessoas com o vírus da imunodeficiência adquirida (HIV) no mundo. Com o advento dos antirretrovirais, observou-se aumento da obesidade e de taxas metabólicas nos pacientes em tratamento.

    Background. Obesity is considered a low-grade inflammatory state and has been associated with increased acute phase proteins as well as changes in serum fatty acids. Few studies have assessed associations between acute phase proteins and serum fatty acids in morbidly obese patients. Objective. To investigate the relationship between acute phase proteins (C-Reactive Protein, Orosomucoid, and Albumin) and serum fatty acids in morbidly obese patients. Methods. Twenty-two morbidly obese patients were enrolled in this study. Biochemical and clinical data were obtained before bariatric surgery, and fatty acids measured in preoperative serum. Results. Orosomucoid was negatively correlated with lauric acid (P = 0.027) and eicosapentaenoic acid (EPA) (P = 0.037) and positively with arachidonic acid (AA) (P = 0.035), AA/EPA ratio (P = 0.005), and n-6/n-3 polyunsaturated fatty acids ratio (P = 0.035). C-Reactive Protein (CRP) was negatively correlated with lauric acid (P = 0.048), and both CRP and CRP/Albumin ratio were negatively correlated with margaric acid (P = 0.010, P = 0.008, resp.). Albumin was positively correlated with EPA (P = 0.027) and margaric acid (P = 0.008). Other correlations were not statistically significant. Conclusion. Our findings suggest that serum fatty acids are linked to acute phase proteins in morbidly obese patients. PMID:24167354

    Full Text Available Eldo E Frezza, Mitchell Wacthell1, Bradley Ewing21Center for Metabolic Disease and Texas Tech University, Department of Pathology, 2Rawls Business School, Texas Tech University, Lubbock, TX, USAAbstract: The obesity epidemic is also an economic tragedy. This analysis evaluates the economic effects and the potential to improve the well-being of both individual and societal wealth. Econometric techniques should carefully assess the degree to which obesity affects declines in business output, employment, income, and tax revenues at the regional and national levels. Microeconomics assesses lost productivity and associated wages and profit. Macroeconomics assesses trends associated with employment, inflation, interest rates, money supply, and output. To decrease the adverse economic consequences of the obesity epidemic, policy makers must emphasize bariatric surgery as a cost-effective option for qualified patients. Early intervention, education, and tax rebates for obese individuals who undergo bariatric surgery and for medical centers and doctors would likely have positive economic effects on the whole economy in a few years.Keywords: bariatric surgery, morbid obesity, economics

  12. Heartburn during sleep: a clinical marker of gastro-oesophageal reflux disease in morbidly obese patients.

    Fornari, F; Madalosso, C A S; Callegari-Jacques, S M; Gurski, R R

    2009-02-01

    Gastro-oesophageal reflux disease (GORD) and morbid obesity are entities with increasing prevalence. New clinical strategies are cornerstones for their management. The aim of this study was to assess the prevalence of heartburn during sleep (HDS) and whether this symptom predicts the presence of objective GORD parameters and increased heartburn perception in morbidly obese patients. Ninety-one consecutive morbidly obese patients underwent clinical evaluation, upper gastrointestinal endoscopy and oesophageal pH monitoring. HDS was characterized when patients replied positively to the question, 'Does heartburn wake you from sleep?'. A General Score for Heartburn (GSH) ranging between 0 and 5 was assessed with the question 'How bad is your heartburn?'. HDS was reported by 33 patients (36%). More patients with HDS had abnormal acid contact time or reflux oesophagitis than patients without HDS (94%vs 57%, P heartburn preceded by acid reflux in diurnal (39%vs 9%; P heartburn. HDS occurs in a significant minority of patients with morbid obesity and has high positive predictive value for GORD. Symptomatic reflux during the sleep seems to be a marker of increased heartburn perception in this population.

    Morbidly obese patients are at risk for nonalcoholic steatohepatitis (NASH) even in the absence of risk factors for liver disease. Unfortunately, NASH is usually not clinically evident, and a definitive, noninvasive test for NASH does not exist. Resistin, a cytokine originating from adipose tissue, is involved in insulin resistance and also initiates proinflammatory signaling from hepatic stellate cells. This study explores the relationship between resistin expression and liver pathology in bariatric surgery patients. Blood samples from 30 patients undergoing bariatric surgery were collected. Total RNA was extracted and cDNA was synthesized. Quantitative RT-PCR was used to quantify relative gene expression using 18s rRNA gene as an internal control. Wedge liver biopsies from these patients were sectioned and stained. Based on a previously published scoring method, biopsies were assigned an overall NASH severity score and subscores for steatosis, inflammation, and fibrosis. Results were analyzed by using Student's t test. Resistin mRNA levels ranged from 0.5 to 9.7. A group of five patients with very high resistin expression (>4) was identified. These patients had a significantly higher average NASH score compared with the rest of the group (7.9 vs. 4.48, p = 0.019). Steatosis and inflammation scores were significantly higher in the high-resistin group (p < 0.05 for both comparisons). There also was a trend toward higher fibrosis score in this group, which approached statistical significance (p = 0.051). In morbidly obese patients, high resistin expression in serum is associated with hepatic steatosis, inflammation, and fibrosis. The development of elevated resistin expression may represent a link between obesity and the onset of steatohepatitis.

  16. Epidemiology, trends, and morbidities of obesity and the metabolic syndrome.

    Bray, George A; Bellanger, Tracy

    2006-02-01

    Obesity has been described as an epidemic because of the rapid increase in the number of overweight and obese individuals over the past 20 yr. This increasing prevalence of obesity is a worldwide phenomenon affecting both children and adults. The metabolic syndrome is a constellation of central adiposity, impaired fasting glucose, elevated blood pressure, and dyslipidemia (high triglyceride and low HDL cholesterol). When three of these five criteria are present, the risk of cardiovascular disease and diabetes is increased 1.5- to 2-fold. As body weight, expressed as the BMI, rises, there are a number of other diseases that are associated with it. First, life span is shortened and the risk of sudden death increases. Second, the risk of diabetes, gall bladder disease, hypertension, heart disease, osteoarthritis, sleep apnea, and certain forms of cancer also increase.

    The study objective was to evaluate meropenem population pharmacokinetics and pharmacodynamics in nonobese, obese, and morbidly obese patients. Forty adult patients-11 nonobese (body mass index [BMI] calculate probability of target attainment (PTA) for 5 dosing regimens, infused over 0.5 and 3 hours, using fT>MIC of 40%, 54%, and 100% of the dosing interval. A 2-compartment linear-elimination model best described the serum concentration-time data, and creatinine clearance was significantly associated with systemic clearance. Pharmacokinetic parameters were not significantly different among patient groups. In patients with creatinine clearances ≥50 mL/min, all simulated dosing regimens achieved >90% PTA at 40% fT>MIC in all patient groups at MICs ≤2 mg/L. Only 500 mg q8h, infused over 0.5 hour, did not achieve >90% PTA at 54% fT>MIC in nonobese and morbidly obese patients. At 100% fT>MIC, 1 g q6h and 2 g q8h, infused over 3 hours, reliably achieved >90% PTA in all patient groups. Meropenem pharmacokinetics are comparable among nonobese, obese, and morbidly obese patients. Standard dosing regimens provide adequate pharmacodynamic exposures for susceptible pathogens at 40% and 54% fT>MIC, but prolonged infusions of larger doses are needed for adequate exposures at 100% fT>MIC. Dosage adjustments based solely on body weight are unnecessary. © 2016, The American College of Clinical Pharmacology.

  18. Lowered testosterone in male obesity: Mechanisms, morbidity and management

    Mark Ng Tang Fui

    2014-04-01

    Full Text Available With increasing modernization and urbanization of Asia, much of the future focus of the obesity epidemic will be in the Asian region. Low testosterone levels are frequently encountered in obese men who do not otherwise have a recognizable hypothalamic-pituitary-testicular (HPT axis pathology. Moderate obesity predominantly decreases total testosterone due to insulin resistance-associated reductions in sex hormone binding globulin. More severe obesity is additionally associated with reductions in free testosterone levels due to suppression of the HPT axis. Low testosterone by itself leads to increasing adiposity, creating a self-perpetuating cycle of metabolic complications. Obesity-associated hypotestosteronemia is a functional, non-permanent state, which can be reversible, but this requires substantial weight loss. While testosterone treatment can lead to moderate reductions in fat mass, obesity by itself, in the absence of symptomatic androgen defi ciency, is not an established indication for testosterone therapy. Testosterone therapy may lead to a worsening of untreated sleep apnea and compromise fertility. Whether testosterone therapy augments diet- and exercise-induced weight loss requires evaluation in adequately designed randomized controlled clinical trials.

  19. Are English CT departments and radiographers prepared for the morbidly obese patient?

    2017-01-01

    Introduction: Morbid obesity is increasing in England, as is the use of CT scanning. All CT scanners have weight and body width limits. It is imperative that the radiographer performing the scan is aware of these limits, particularly in an emergency. This study aim was to determine whether radiographers are aware of their scanner limits, where they may be able to send a patient who exceeds these limits and whether a formal protocol exists. The secondary aim of the study was to determine capacities of scanners in acute trusts throughout England. Methods: CT radiographers from 86 English Hospital Trusts with Emergency Departments were contacted and asked questions regarding their CT scanners and their practice of CT scanning morbidly obese patients. Results: 21% of CT radiographers did not know the maximum width capacity of their scanner. Only 24% knew where a nearby larger capacity scanner was located and only 3% had a formal protocol for scanning obese patients. Weight capacities ranged from 147 to 305 kg. Width capacities ranged from 55 to 100 cm. 70% had weight capacity 226 kg or less and 70% had size capacity of 78 cm or less. Conclusion: Patients over 226 kg or 78 cm may not be accommodated in most (70%) trusts in England. Lack of knowledge of scanner capacities and alternative scanners for morbidly obese patients could have consequences for these patients, particularly in an emergency. The authors advise that all acute trusts have a protocol regarding CT scanning morbidly obese to prevent delays in accessing imaging. - Highlights: • Radiographer knowledge about CT scan capacity is somewhat lacking, potentially delaying emergency management. • Most CT scanners in England will not accommodate patients over 226 kg or 78 cm. • Most centres do not have a formal protocol for CT scanning obese patients. • Animal CT scanners are not likely to be useful alternatives for most patients.

    Full Text Available Scott S Um1, Wendelin Slusser2, Daniel A DeUgarte11Department of Surgery, David Geffen School of Medicine at UCLA, Los Angeles, CA, USA; 2Department of Pediatrics, David Geffen School of Medicine at UCLA, Los Angeles, CA, USAAbstract: Adolescent obesity is a growing health concern that can have immense physical and psychological impact. Treatment of morbidly obese adolescents should include a multidisciplinary team to address medical comorbidities, diet, physical activity, mental health, and behavior modification. Anti-obesity pharmacologic agents have a limited role in the treatment of adolescents because of concerns with side effects, safety, and efficacy. Orlistat (GlaxoSmithKline, Moon Township, PA is the only approved medication for weight-loss in adolescents. However, it is associated with gastrointestinal side effects and its long-term efficacy is unknown. Bariatric surgery is the most effective therapy to treat morbid obesity. However, adolescents must meet rigorous criteria and have appropriate cognitive, psychological, and social clearance before being considered for surgical intervention. Gastric bypass remains the gold standard bariatric operation. The adjustable gastric band is not FDA-approved for use in patients under 18 years of age. Sleeve gastrectomy is a promising procedure for adolescents because it avoids an intestinal bypass and the implantation of a foreign body. Prospective longitudinal assessment of bariatric surgery procedures is required to determine long-term outcomes. In this manuscript, we review the treatment options, efficacy, and impact on quality of life for morbidly obese adolescents.Keywords: bariatric surgery, morbid obesity, weight loss, adolescent

    Endovascular aneurysm repair (EVAR) with percutaneous femoral access (PEVAR) has several potential advantages. Morbidly obese (MO) patients present unique anatomical challenges and have not been specifically studied. This study examines the trends in the use of PEVAR and its surgical outcomes compared with open femoral cutdown (CEVAR) in MO patients. The American College of Surgeons National Surgical Quality Improvement Program files for the years 2005 to 2013 were reviewed. The study included all MO patients (body mass index [BMI] ≥40 kg/m 2 ) undergoing EVAR. Patients were categorized as having CEVAR if they had any one of 11 selected Current Procedural Terminology (American Medical Association, Chicago, Ill) codes describing an open femoral procedure. The PEVAR group included any remaining patients who had only codes for EVAR and endovascular procedures. Linear correlation was used to evaluate temporal trends in the use of PEVAR among MO patients. Baseline comorbidities and surgical outcomes were compared between the PEVAR and CEVAR groups using χ 2 tests or t-tests. There were 833 MO patients (470 CEVAR and 363 PEVAR) constituting 3.0% of all patients undergoing EVAR. The use of PEVAR in MO patients significantly increased from 27.3% of total EVARs in the years 2005 to 2006 to 48.6% in 2013 (P = .039). The two groups had similar baseline characteristics, including age, BMI, comorbidities, and emergency procedures, except for history of severe chronic obstructive pulmonary disease (29.6% CEVAR vs 22.6% PEVAR; P = .024). PEVAR patients had shorter duration of anesthesia (244 vs 260 minutes; P = .048) and shorter total operation time (158 vs 174 minutes; P = .002). PEVAR patients had significantly decreased wound complications (5.5% vs 9.4%; P = .039). There was a trend towards PEVAR patients being more likely to be discharged home than to a facility (93.6% vs 87.8%; P = .060). There was no difference in any other complication or mortality.

    Overweight and obesity are afflictions that lead to an increased risk of health problems including joint problems. The aim of the study was to assess the condition of articular cartilage in obese adolescent patients suffering from knee pain. MRI of 24 knees of 20 morbidly obese patients, mean age 14.2 years, was performed in an open 1.0 Tesla MR system, where the cartilage, the quality and structure of the menisci, and the presence or absence of surrounding changes was examined. In all patients a cartilage lesion in at least one region of the knee could be detected. Retropatellar cartilage lesions have been found in 19 knees. Ten cartilage lesions grade I, and four lesions grade II have been described in the lateral compartment of the knee, whereas the medial compartment showed in eight cases a grade I, in 13 cases a grade II and in two cases a grade III cartilage lesion. Meniscal changes were assessed in most patients. Morbidly obese children and adolescents show major abnormalities in the articular cartilage of the knee. Whether obesity alone is the causal factor for the development of the pattern of these changes, remains to be seen. (orig.)

    2005-04-01

    Full Text Available INTRODUCTION: Management of urolithiasis in morbidly obese patients is usually associated with higher morbidity and mortality compared to non-obese patients. In morbidly obese patients, since the kidney and stone are at a considerable distance from the skin (compared to non-obese patients difficulty may be found in positioning the patient so that the stone is situated at the focal point of the lithotripter. OBJECTIVE: To evaluate the outcomes and cost-efficiency of extracorporeal shock wave lithotripsy (ESWL in the treatment of renal pelvicalyceal stones sized between 6 and 20 mm in morbidly obese patients. MATERIALS AND METHODS: Using various aids, such as mobile overtable module, extended shock pathway and abdominal compression 37 patients with body mass index more than 40 kg/m2 were treated using the Siemens Lithostar-plus third generation lithotripter. The size of renal pelvicalyceal stones was between 6 and 20 mm. Treatment costs for shock wave lithotripsy were calculated. RESULTS: The overall stone free rate at 3 months of 73% was achieved. The mean number of treatments per patient was 2.1. The post-lithotripsy secondary procedures rate was 5.4%. No complications, such as subcapsular haematoma or acute pyelonephritis were recorded. The most effective (87% success rate and cost-efficient treatment was in the patients with pelvic stones. The treatment of the patients with low caliceal stones was effective in 60% only. The cost of the treatment of the patients with low calyceal stones was in 1.8 times higher than in the patients with pelvic stones. CONCLUSION: We conclude that ESWL with the Siemens Lithostar-plus is the most effective and cost-efficient in morbidly obese patients with pelvic stones sized between 6 and 20 mm. 87% success rate was achieved. The increased distance from the skin surface to the stone in those patients does not decrease the success rate provided the stone is positioned in the focal point or within 3 cm of it on the

    We present this preliminary investigation into the safety and feasibility of endovascular therapy for morbid obesity in a swine model. A flow-limiting, balloon-expandable covered stent was placed in the superior mesenteric artery of three Yorkshire swine after femoral arterial cutdown. The pigs were monitored for between 15 and 51 days after the procedure and then killed, with weights obtained at 2-week increments. In the two pigs in which the stent was flow limiting, a reduced rate of weight gain (0.42 and 0.53 kg/day) was observed relative to the third pig (0.69 kg/day), associated with temporary food aversion and signs of mesenteric ischemia in one pig.

    Obesity is a chronic disease characterized by increased accumulation of body fat. We evaluated the socioeconomic aspects, body composition, risk of metabolic complications associated with obesity, eating habits and lifestyle in both women and men adults and elderly with body mass index (BMI) > 40 kg/m². Among the subjects studied, 79% (n = 32) are female, 5% (n = 2) smokers, 39% (n = 16) use alcohol and only 24% (n = 10) are practitioners of physical exercise. The higher food intake was breads, followed by rice. The daily intake of fruits and vegetables is low. Positive correlation between consumption of sugar and BMI and abdominal circumference (AC) was observed. In summary, was found that morbidly obese patients that looking for nutritional counseling presents increased body fat, poor eating habits and sedentary lifestyle.

    The purpose of the study was to study the impact of the two most common bariatric surgery techniques on paracetamol pharmacokinetics (a marker of gastric emptying) and caffeine metabolism (a marker of liver function). In the present prospective study, we studied 24 morbid obese patients before, at 4 weeks, and 6 months after having undergone sleeve gastrectomy (n = 10) or Roux-en-Y gastric bypass (n = 14). For comparative purposes, 28 healthy controls (14 normal weights and 14 overweights) were also included in the study. Paracetamol pharmacokinetics was altered in the obese participants leading to lower bioavailability. Bariatric surgery resulted in faster absorption and normalized pharmacokinetic parameters, prompting an increase in paracetamol bioavailability. No differences were found between surgical procedures. In the case of caffeine, the ratio paraxanthine/caffeine did not differ between morbid obese and healthy individuals. This ratio remained unmodified after surgery, indicating that the liver function (assessed by cytochrome P450 1A2 activity) was unaffected by obesity or bariatric surgery. Paracetamol pharmacokinetics and caffeine plasma levels are altered in severely obese patients. The two studied bariatric surgical techniques normalize paracetamol oral bioavailability without impairing the liver function (measured by cytochrome P450 1A2 activity).

    2009-06-01

    The causes of obesity are multifactorial but may include dysregulation of a family of related genes, such as the peroxisome proliferator activated receptor gamma (PPARgamma). When activated, the PPARgamma pathway promotes lipid metabolism. This study used microarray technology to evaluate differential gene expression profiles in obese patients undergoing bariatric surgery. The study enrolled six morbidly obese patients with a body mass index (BMI) exceeding 35 and four nonobese individuals. Blood samples were stabilized in PaxGene tubes (PreAnalytiX), and total RNA was extracted. Next, 100 ng of total RNA was amplified and labeled using the Ovation RNA Amplification System V2 with the Ovation whole-blood reagent (NuGen) before it was hybridized to an Affymetrix (Santa Clara, CA) focus array containing more than 8,500 verified genes. The data were analyzed using an analysis of variance (ANOVA) (p < 0.05) in the GeneSpring program, and potential pathways were identified with the Ingenuity program. Real-time quantitative reverse transcriptase-polymerase chain reaction was used to validate the array data. A total of 97 upregulated genes and 125 downregulated genes were identified. More than a 1.5-fold change was identified between the morbidly obese patients and the control subjects for a cluster of dysregulated genes involving pathways regulating cell metabolism and lipid formation. Specifically, the PPARgamma pathway showed a plethora of dysregulated genes including tumor necrosis factor-alpha (TNFalpha). In morbidly obese patients, TNFalpha expression was increased (upregulated) 1.6-fold. These findings were confirmed using quantitative polymerase chain reaction with a 2.8-fold change. Microarrays are a powerful tool for identifying biomarkers indicating morbid obesity by analyzing differential gene expression profiles. This study confirms the association of PPARgamma with morbid obesity. Also, these findings in blood support previous work documented in tissue

    Background: Preoperative anemia may affect postoperative mortality and morbidity following elective cranial operations. Methods: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to identify elective cranial neurosurgical cases (2006-2012). Morbidity was defined as wound infection, systemic infection, cardiac, respiratory, renal, neurologic, and thromboembolic events, and unplanned returns to the operating room. For 30-day postoperative mortality and morbidity, adjusted odds ratios (ORs) were estimated with multivariable logistic regression. Results: Of 8015 patients who underwent elective cranial neurosurgery, 1710 patients (21.4%) were anemic. Anemic patients had an increased 30-day mortality of 4.1% versus 1.3% in non-anemic patients (P neurosurgery was independently associated with an increased risk of 30-day postoperative mortality and morbidity when compared to non-anemic patients. A hematocrit level below 33% (Hgb 11 g/dl) was associated with a significant increase in postoperative morbidity. PMID:25422784

    2009-01-01

    Binge eating episodes characterized by loss of control are hypothesized to be accompanied by changes in hypothalamic pituitary adrenal (HPA) axis functioning. Cortisol is an end product of this neuroendocrine stress system. The aim of this study was to examine the cortisol levels and the awakening cortisol response (ACR) in obese persons showing binge eating after surgery for morbid obesity. Sixteen obese women with binge eating disorder (BED) and 18 obese women without BED participated in the study. Means+/-SD: age 43 +/- 15, body mass index 40 +/- 8. Salivary cortisol, anthropometric assessments, and the eating disorder examination interview were taken. Women with BED showed a significantly lower waist-to-hip ratio and cortisol levels during the day than women without BED, whereas the ACR did not differ. Our cross-sectional study in a small sample generates the hypothesis that neuroendocrine regulation differs between obese women with and without BED after obesity surgery. This finding needs replication in future studies that should also examine the causal direction of the observed association.

  15. Long-term impact of overweight and obesity in childhood and adolescence on morbidity and premature mortality in adulthood: systematic review.

    Reilly, J J; Kelly, J

    2011-07-01

    The last systematic review on the health consequences of child and adolescent obesity found little evidence on consequences for adult health. The present study aimed to summarize evidence on the long-term impact of child and adolescent obesity for premature mortality and physical morbidity in adulthood. Systematic review with evidence searched from January 2002 to June 2010. Studies were included if they contained a measure of overweight and/or obesity between birth and 18 years (exposure measure) and premature mortality and physical morbidity (outcome) in adulthood. Five eligible studies examined associations between overweight and/or obesity, and premature mortality: 4/5 found significantly increased risk of premature mortality with child and adolescent overweight or obesity. All 11 studies with cardiometabolic morbidity as outcomes reported that overweight and obesity were associated with significantly increased risk of later cardiometabolic morbidity (diabetes, hypertension, ischaemic heart disease, and stroke) in adult life, with hazard ratios ranging from 1.1-5.1. Nine studies examined associations of child or adolescent overweight and obesity with other adult morbidity: studies of cancer morbidity were inconsistent; child and adolescent overweight and obesity were associated with significantly increased risk of later disability pension, asthma, and polycystic ovary syndrome symptoms. A relatively large and fairly consistent body of evidence now demonstrates that overweight and obesity in childhood and adolescence have adverse consequences on premature mortality and physical morbidity in adulthood.

    Obesity is a global epidemic that affects 500 million people worldwide and is predicted to increase to one billion people by 2030. The prevalence of obesity is increasing across populations in South Africa. However, questions still remain surrounding the predisposing factors and obesity-related health problems especially in the rural areas. This study evaluated several lifestyle factors such as dietary habits, physical activity, smoking, alcohol intake, co-morbidities and their association with the prevalence of obesity and overweight in Nkonkobe Municipality of the Eastern Cape. A cross-sectional, population-based survey was conducted among 118 residents in four rural/sub-urban townships of the study area. Measurements including weight, height, body mass index (BMI), physical activity and dietary habits were determined using a validated questionnaire. The overall prevalence of obesity and overweight was 38 and 19%, respectively. The highest prevalence of obesity (70%) was observed among those who do not undertake any physical activity. Close to half (48.48%) of the respondents who eat fast foods always were obese, and 30.30% were overweight; when combined, the prevalence for obesity is 78.78%. A negative association with obesity was observed among regular smokers (26.92%) and consumers of alcohol (4.00%). Arthritis, hypertension and tuberculosis were co-morbidities significantly (P fast and fried foods, low fruit and vegetable consumption as well as arthritis, hypertension and tuberculosis were significant risk factors of obesity in Nkonkobe Municipality.

    The prevalence of morbid obesity is increasing rapidly. Weight reduction is very difficult using diet restriction and physical activity alone. Sibutramine has been shown to be effective and safe as an adjuvant therapy to diet restrictions. To describe our experience using sibutramine in weight reduction treatment of adolescents suffering from morbid obesity. The study group comprised 20 young persons (13 females, mean age 15 years 4 months, range 13-18 years) with morbid obesity (body mass index above the 95th percentile for age and/or > or =30 kg/m2) who were treated with sibutramine 10 mg once a day for 1 year. Mean BMI was 40 +/- 5.6 kg/m2 (range 30.1 - 49.5 kg/m2) at the beginning of treatment. Most patients showed an early weight reduction to mean BMI 39.3 +/- 4.9 and 35.9 +/- 5.7 at 3 and 6 months respectively, but stopped losing weight over the next 6 months. During the follow-up period 17 patients discontinued the treatment. The main reason for dropout was the slow rate of weight reduction after 6 months. Patients suffering from concomitant disorders (severe asthma, hypertension, sleep obstructive apnea) showed improvement after weight reduction. Adverse reactions from the treatment were transient, mild and well tolerated. Sibutramine may help in achieving weight reduction for a short period and in improving concomitant health problems, however its long-term effect is limited.

    Metabolomic studies aimed to dissect the connection between the development of type 2 diabetes and obesity are still scarce. In the present study, fasting serum from sixty-four adult individuals classified into four sex-matched groups by their BMI [non-obese versus morbid obese] and the increased risk of developing diabetes [prediabetic insulin resistant state versus non-prediabetic non-insulin resistant] was analyzed by LC- and FIA-ESI-MS/MS-driven metabolomic approaches. Altered levels of [lyso]glycerophospholipids was the most specific metabolic trait associated to morbid obesity, particularly lysophosphatidylcholines acylated with margaric, oleic and linoleic acids [lysoPC C17:0: R=-0.56, p=0.0003; lysoPC C18:1: R=-0.61, p=0.0001; lysoPC C18:2 R=-0.64, pprediabetes and insulin resistance in a BMI-independent manner [fasting insulin: R=0.37, p=0.0479; HOMA-IR: R=0.37, p=0.0468]. Minority sphingolipids including specific [dihydro]ceramides and sphingomyelins also associated with the prediabetic insulin resistant state, hence deserving attention as potential targets for early diagnosis or therapeutic intervention.

  20. [Morbidity rate of obesity in children in ukraine. Overweight as noncontagious disease risk factor].

    Заболотна, Ірина Е

    The upsurge of prevalence rate of obesity and overweight that in the majority of cases traces back to childhood is a risk factor of the most common noncontagious diseases in adults. The aim was to analyze prevalence of obesity in children in Ukraine and to conduct the pilot study of medical condition of overweight children. Official state statistics of prevalence rate of obesity in kids and screening data of anthropometric characteristics, arterial tension levels, physical performance decrement and medical condition of children (boys - 50, girls - 90, average age - 15,1±0,1 years) was used in research. Data calculation performed by Statistica v. 6.0 software. Over the past few decades, the morbidity rate of obesity in children in Ukraine has greatly increased, especially in year class 15-17. Insufficient diagnosis of obesity in children is the consequence of the inadequacy of the existing system of preventive care and monitoring survey of decease risk factors. Children with body mass index (BMI) above normal have a risk of work decrement in 5,2 times (odds ratio, OR=5,2, CI95%: 1,7-10,6). Such children have higher risk of development of the diseases of the respiratory system (OR=8,1; CI95%: 3,9-13,6) and allergic dermatitis (OR=7,7; CI95%: 3,7-12,9). The odds ratio of arterial hypertension in such children is equal to 3,46±0,3 (95%CI: 2,0-5,9). According to prediction calculations, the situation with the increase of prevalence rate of obesity in children in Ukraine is unfavorable. The introduction of measures aimed at finding children with obesity, their registration and monitoring of patients' health with due regard to decease risk factors at the primary care level would conduce to improving prevention of obesity and prevention of alimentary diseases progression.

    Regarding technical difficulties that obese body habitus might impose to percutaneous nephrolithotomy (PNL) success and higher risk of peri-operative complications in this group of patients, we decided to retrospectively gather data from our patients during past 8 years to determine the stone free and complication rates. Between January 2007-December 2015, seventy-eight obese patients with body mass index over 35 who had indication for PNL including stones larger than 2 cm in pelvi-calyceal system or smaller extracorporeal shock wave lithotripsy (ESWL) resistant stones or who were not a fit candidate for ESWL due to increased skin to target distance, with no contraindication of PNL (including bleeding diathesis, inability to be positioned in prone) were enrolled. They were randomly assigned to group 1 (standard PNL with nephrostomy and ureteral stent) or group 2 (totally tubeless PNL with no ureteral stent and no nephrostomy). The outcomes were compared. The transfusion rate, operation time, and the hemoglobin drop were same across the groups (p>0.05). Total analgesic use was equivalent of 33.8 vs. 14.7 mgs of morphine sulfate (18-77 mg) and was significantly lower in total tubeless group (p=0.001). Return to normal activity was described as total number of in-patient and outpatient days from time of admission to the point which the patients returns to normal life activity such as going to job or school and was 19.4 vs. 9.3 days (6-30 days, p=0.001). Totally tubeless PNL in obese subjects would have lower analgesic use and return to normal activity versus standard PNL. Totally tubeless PNL is recommended for obese patients.

    Full Text Available A morbidly obese male who sustained blunt trauma chest with bilateral pneumothorax was referred to the intensive care unit for management of his condition. Problems encountered in managing the patient were gradually increasing hypoxemia (chest trauma with multiple rib fractures with lung contusions and difficult mask ventilation and intubation (morbid obesity, heavy jaw, short and thick neck. We performed awake endotracheal intubation using an intubating laryngeal mask airway (ILMA size 4 and provided mechanical ventilation to the patient. This report suggests that ILMA can be very useful in the management of difficult airway outside the operating room and can help in preventing adverse events in an emergency setting.

    Full Text Available Dysfunctional cognitions may be associated with unhealthy eating behaviors seen in individuals with obesity. However, dysfunctional cognitions commonly occur in individuals with poor mental health independently of weight. We examined whether individuals with morbid obesity differed with regard to dysfunctional cognitions when compared to individuals of normal weight, when mental health status was controlled for. 111 participants—53 with morbid obesity and 58 of normal weight—were assessed with the Mini-Mental State Examination, Young Schema Questionnaire, Cognitive Distortions Questionnaire, Depression, Anxiety and Stress Scale, and a Demographic and Clinical Questionnaire. Participants with morbid obesity showed higher scores in one (insufficient self-control/self-discipline of 15 early maladaptive schemas and in one (labeling of 15 cognitive distortions compared to participants of normal weight. The difference between groups for insufficient self-control/self-discipline was not significant when mental health status was controlled for. Participants with morbid obesity showed more severe anxiety than participants of normal weight. Our findings did not show clinically meaningful differences in dysfunctional cognitions between participants with morbid obesity or of normal weight. Dysfunctional cognitions presented by individuals with morbid obesity are likely related to their individual mental health and not to their weight.

    Obesity and type 2 diabetes are associated with impaired skeletal muscle mitochondrial metabolism. As an intrinsic characteristic of an individual, skeletal muscle mitochondrial dysfunction could be a risk factor for weight gain and obesity-associated co-morbidities, such as type 2 diabetes. On the other hand, impaired skeletal muscle metabolism could be a consequence of obesity. We hypothesize that marked weight loss after bariatric surgery recovers skeletal muscle mitochondrial function. Skeletal muscle mitochondrial function as assessed by high-resolution respirometry was measured in 8 morbidly obese patients (body mass index [BMI], 41.3±4.7 kg/m(2); body fat, 48.3%±5.2%) before and 1 year after bariatric surgery (mean weight loss: 35.0±8.6 kg). The results were compared with a lean (BMI 22.8±1.1 kg/m(2); body fat, 15.6%±4.7%) and obese (BMI 33.5±4.2 kg/m(2); body fat, 34.1%±6.3%) control group. Before surgery, adenosine diphosphate (ADP)-stimulated (state 3) respiration on glutamate/succinate was decreased compared with lean patients (9.5±2.4 versus 15.6±4.4 O2 flux/mtDNA; Psurgery, mitochondrial function was comparable to that of lean controls (after weight loss, 12.3±5.5; lean, 15.6±4.4 O2 flux/mtDNA). In addition, we observed an increased state 3 respiration on a lipid substrate after weight loss (10.0±3.2 versus 14.0±6.6 O2 flux/mtDNA; Pweight loss.

    2014-01-01

    Full Text Available Background: Providing anesthesia for gastrointestinal (GI endoscopy procedures in morbidly obese patients is a challenge for a variety of reasons. The negative impact of obesity on the respiratory system combined with a need to share the upper airway and necessity to preserve the spontaneous ventilation, together add to difficulties. Materials and Methods: This retrospective cohort study included patients with a body mass index (BMI >40 kg/m 2 that underwent out-patient GI endoscopy between September 2010 and February 2011. Patient data was analyzed for procedure, airway management technique as well as hypoxemic and cardiovascular events. Results: A total of 119 patients met the inclusion criteria. Our innovative airway management technique resulted in a lower rate of intraoperative hypoxemic events compared with any published data available. Frequency of desaturation episodes showed statistically significant relation to previous history of obstructive sleep apnea (OSA. These desaturation episodes were found to be statistically independent of increasing BMI of patients. Conclusion: Pre-operative history of OSA irrespective of associated BMI values can be potentially used as a predictor of intra-procedural desaturation. With suitable modification of anesthesia technique, it is possible to reduce the incidence of adverse respiratory events in morbidly obese patients undergoing GI endoscopy procedures, thereby avoiding the need for endotracheal intubation.

    Full Text Available Abstract Background Obesity has been associated with increased incidence of colorectal cancer. Adipose tissue dysfunction accompanied with alterations in the release of adipocytokines has been proposed to contribute to cancer pathogenesis and progression. The aim of this study was to analyze plasma concentrations of several adipose tissue expressed hormones in colorectal cancer patients (CRC and morbidly obese (MO patients and to compare these concentrations to clinicopathological parameters. Methods Plasma concentrations of adiponectin, resistin, leptin, active plasminogen activator inhibitor (PAI-1, monocyte chemotactic protein (MCP-1, interleukin (IL-1 alpha, and tumor necrosis factor (TNF-alpha were determined in 67 patients operated on for CRC (31 rectal cancers, 36 colon cancers, 37 patients operated on for morbid obesity and 60 healthy blood donors (BD. Results Compared to BD, leptin concentrations were lowered in CRC patients whereas those of MO patients were elevated. Adiponectin concentrations were only lowered in MO patients. Concentrations of MCP-1, PAI-1, and IL-1 alpha were elevated in both CRC and MO patients, while resistin and TNF-alpha were similarly expressed in MO and CRC patients compared to BD. Resistin concentrations positively correlated with tumor staging (p Conclusions The results suggest that both MO and CRC have low-grade inflammation as part of their etiology.

    Morbid obesity is rising around the world. It can cause unpleasant appearance and body image. Most of the studies have aimed to evaluate the psychopathology of overweight and obesity and paying attention to mental well-being in morbid obese individuals is rare. Therefore, this study aimed to assess the relationship between body image and psychological well-being in morbid obese patients. This cross-sectional study, using simple random sampling method, was done on 124 morbid obese patients who referred to obesity clinic in Shiraz from 2016 to 2017. The data were collected by body image index and psychological well-being questionnaire. Results were analyzed using descriptive statistics, Pearson correlation coefficient test, ANOVA, and Regression analysis. The results showed a significant relationship between body image and psychological well-being (r=0.43) (Pimage and all the subscales of psychological well-being except autonomy and purpose in life (Pimage (Pimage and those of psychological well-being in different categories of body mass index (BMI) (P>0.05). Final results indicated that body image defects caused by obesity could lie in negative psychological well-being in all aspects. This study can promote health clinicians' knowledge in supporting of mental status of obese individuals. It is suggested that preventing and supporting intervention should be performed as effective methods for encountering and coping with psychological effects of obesity.

  13. Could the improvement of obesity-related co-morbidities depend on modified gut hormones secretion?

    Finelli, Carmine; Padula, Maria Carmela; Martelli, Giuseppe; Tarantino, Giovanni

    2014-01-01

    Obesity and its associated diseases are a worldwide epidemic disease. Usual weight loss cures - as diets, physical activity, behavior therapy and pharmacotherapy - have been continuously implemented but still have relatively poor long-term success and mainly scarce adherence. Bariatric surgery is to date the most effective long term treatment for morbid obesity and it has been proven to reduce obesity-related co-morbidities, among them nonalcoholic fatty liver disease, and mortality. This article summarizes such variations in gut hormones following the current metabolic surgery procedures. The profile of gut hormonal changes after bariatric surgery represents a strategy for the individuation of the most performing surgical procedures to achieve clinical results. About this topic, experts suggest that the individuation of the crosslink among the gut hormones, microbiome, the obesity and the bariatric surgery could lead to new and more specific therapeutic interventions for severe obesity and its co-morbidities, also non surgical.

    Persons with "metabolically healthy" obesity may develop cardiometabolic complications at a lower rate than equally obese persons with evident metabolic syndrome. Even morbidly obese individuals vary in risk profile. Persistent organic pollutants (POPs) are widespread environmental chemicals that impair metabolic homeostasis. We explored whether prevalence of metabolic syndrome in morbidly obese individuals is associated with serum concentrations of POPs. A cross-sectional study among 161 men and 270 women with BMI >35 kg/m 2 and comorbidity, or >40 kg/m 2 . Circulating concentrations of 15 POPs were stratified by number of metabolic syndrome components. In multiple logistic regression analysis odds ratios between top quartile POPs and metabolic risk factors versus POPs below the top quartile were calculated adjusting for age, gender, body mass index, smoking status, alcohol consumption and cholesterol concentrations. Age-adjusted concentrations of trans-nonachlor and dioxin-like and non-dioxin-like polychlorinated biphenyls (PCBs) increased with number of metabolic syndrome components in both genders (p metabolic syndrome as were dioxin-like and non-dioxin-like PCBs (OR 2.3 [95% CI 1.3-4.0]; OR 2.5 [95% CI 1.3-4.8] and 2.0 [95% CI 1.1-3.8], respectively). Organochlorine pesticides were associated with HDL cholesterol and glucose (OR = 2.0 [95% CI = 1.1-3.4]; 2.4 [95% CI = 1.4-4.0], respectively). Dioxin-like PCBs were associated with diastolic blood pressure, glucose and homeostatic model assessment-insulin resistance index (OR = 2.0 [95% CI = 1.1-3.6], 2.1 [95% CI = 1.2-3.6] and 2.1 [95% CI = 1.0-4.3], respectively). In subjects with morbid obesity, metabolic syndrome was related to circulating levels of organochlorine pesticides and PCBs suggesting that these compounds aggravate clinically relevant complications of obesity.

    Full Text Available The purpose of this study was to predict low, moderate, hard and very hard physical activity (PA and walking/biking/jogging based PA. One-hundred and fifty-nine severe to morbid obese African-American adolescents participated. We predicted 8% of the variance in hard PA largely due to family support and 10% of the variance in very hard PA due to other support (e.g. counselor and having home PA equipment. We also predicted 10% of the variance in walking/biking/jogging due to the walkability of the neighborhood. Our findings support the value of social support and environmental supports in helping obese African American adolescents increase PA.

    2015-02-01

    The aim of this study is to assess the rate of work participation and disability pension, and identify predictors for sickness absence and disability pension, among morbidly obese individuals. The data were collected from the Obesity Surgery Registry at Førde Central Hospital and consists of patients undergoing bariatric surgery between April 2001 and February 2013. Multivariate logistic regression was performed to identify predictors of sickness absence and disability pension. The sample consisted of 576 patients (63.9 % females) with a mean (range, SD) age of 41.7 (18-66, 10.6) and a mean body mass index (BMI) of 47.7 (32.5-80.8, 7.7). Patients working full- or part-time comprised 55.6 % of the sample and 29.7 % received a disability pension; only 46.4 % of the sample received an income from paid work without additional benefits. Having a BMI above 50, lower levels of education, and suffering from four or more comorbidities were significant predictors of sickness absence. Female gender, psychiatric disorders, lower levels of education, asthma, heart failure and suffering from four or more comorbidities were significant predictors of disability pension. The proportion of the work participation and disability pension among this morbidly obese population is of substantial concern, as work participation has proven important for the health-related quality of life. This, combined with the fact that these patients are significantly less educated than the general population, can potentially have grave socioeconomic consequences. Increased knowledge of obesity development and the work history of these patients are needed to implement policies that ensure increased rates of work participation.

    The purpose of this study was to evaluate the effect of weight loss induced in morbidly obese subjects by Roux-en-Y gastric bypass bariatric surgery on the atherogenic features of their plasma lipoproteins. Twenty-one morbidly obese subjects undergoing bariatric surgery were followed up for up to 1 year after surgery. Plasma and lipoproteins were assayed for chemical composition and lipoprotein-associated phospholipase A2 (Lp-PLA2) activity. Lipoprotein size was assessed by non-denaturing polyacrylamide gradient gel electrophoresis, and oxidised LDL by ELISA. Liver samples were assayed for mRNA abundance of oxidative markers. Lipid profile analysis revealed a reduction in the plasma concentrations of cholesterol and triglycerides, which were mainly associated with a significant reduction in the plasma concentration of circulating apoB-containing lipoproteins rather than with changes in their relative chemical composition. All patients displayed a pattern A phenotype of LDL subfractions and a relative increase in the antiatherogenic plasma HDL-2 subfraction (>2-fold; P lipoprotein-bound Lp-PLA2. Our data indicate that the weight loss induced by bariatric surgery ameliorates the atherogenicity of plasma lipoproteins by reducing the apoB-containing Lp-PLA2 activity and oxidised LDL, as well as increasing the HDL-2 subfraction.

    Morbid obesity and obstructive sleep apnea (OSA) interact at an inflammatory level. Bariatric surgery reduces inflammatory responses associated with obesity. Heme oxygenase-1 (HO-1) is an enzyme with anti-inflammatory properties, which might be increased in morbid obesity or OSA. We studied morbidly obese patients with OSA to determine: (a) HO-1 plasma concentrations according to OSA severity and their relationship with insulin resistance and inflammation and (b) the impact of bariatric surgery on HO-1 and parameters of insulin resistance and inflammation. We analyzed the homeostasis model insulin resistance index (HOMA) and plasma concentrations of HO-1, tumor necrosis factor alpha, interleukin-6, interleukin-1-beta, C reactive protein (CRP), and adiponectin according to polysomnography findings in 66 morbidly obese patients before bariatric surgery and 12 months after surgery. Before surgery, HO-1 plasma concentrations were similar in three groups of patients with mild, moderate, and severe OSA, and correlated with HOMA (r = 0.27, p = 0.02). Twelve months after surgery, low-grade inflammation and insulin resistance had decreased in all the groups, but HO-1 plasma concentration had decreased only in the severe OSA group (p = 0.02). In this group, the reduction in HO-1 correlated with a reduction in CRP concentrations (r = 0.43, p = 0.04) and with improved HOMA score (r = 0.37, p = 0.03). Bariatric surgery decreases HO-1 concentrations in morbid obesity with severe OSA, and this decrease is associated with decreases in insulin resistance and in inflammation.

    The European guidelines for bariatric surgery clearly define criteria for operating children with morbid obesity. However the appropriate technique for this age-group has not been identified yet. So far gastric banding and Roux-Y bypass represent the standards, but they demand life-long tolerance of either an artificial device or significant malabsorption. Although laparoscopic sleeve gastrectomy (LSG) demands neither, it has not been advocated for this age-group as a stand-alone technique. We report the outcome and the rationale for this approach in a 16-year-old girl with morbid obesity. The patient had been in an intensive weight loss programme for several years, but within the last 12 months her body weight had increased again dramatically. At referral she presented with a body mass index (BMI) of 43.1 kg/m(2) (height 169 cm, preoperative weight 121 kg) and suffered from co-morbidities as features of a developing metabolic-vascular syndrome such as dyslipidemia and arterial hypertension. Our obesity team and her parents opted for surgery at that time. The patient underwent LSG with a 5-trocar technique. With a gastroscope protecting the lesser curvature, the stomach was resected from the antrum to the fundus using an EndoGIA stapler. The operative time was 95 minutes, there were no perioperative complications and the patient was extubated immediately. An upper GI contrast study on postoperative day 4 showed a tubular gastric remnant with a volume of about 200 ml. The patient's diet was advanced as tolerated to full oral intake, and she was followed-up regularly in our special obesity outpatient clinic. After 12 months she had lost 36 kg (BMI 29 kg/m(2)) and enjoyed sports and activities with friends again. Laboratory studies ruled out malnutrition or vitamin deficiency. LSG is a safe and effective option for bariatric surgery in obese adolescents. It can be offered as a stand-alone restrictive operation and could be extended to a malabsorptive procedure at any

    The obesity epidemic is also an economic tragedy. This analysis evaluates the economic effects and the potential to improve the well-being of both individual and societal wealth. Econometric techniques should carefully assess the degree to which obesity affects declines in business output, employment, income, and tax revenues at the regional and national levels. Microeconomics assesses lost productivity and associated wages and profit. Macroeconomics assesses trends associated with employment, inflation, interest rates, money supply, and output. To decrease the adverse economic consequences of the obesity epidemic, policy makers must emphasize bariatric surgery as a cost-effective option for qualified patients. Early intervention, education, and tax rebates for obese individuals who undergo bariatric surgery and for medical centers and doctors would likely have positive economic effects on the whole economy in a few years.

    Sugammadex, which is used to reverse rocuronium-induced neuromuscular blockade, has a limited and transient effect on activated partial thromboplastin time and prothrombin time. However, no data are available on the effects of sugammadex on coagulation in morbidly obese patients, as assessed by rotational thromboelastometry (ROTEM®). Sixty patients received sugammadex 2 mg/kg or 4 mg/kg to reverse moderate or deep rocuronium-induced neuromuscular blockade (N.=30/group) at the end of surgery under desflurane anesthesia. Arterial blood samples were collected before and 3 min and 30 min after sugammadex administration for ROTEM® analysis, including measurements of clotting time (CT), clot formation time, α angle, and maximum clot firmness in INTEM, EXTEM, and FIBTEM assays. Major and minor bleeding events were also monitored during the postoperative period. Sugammadex 2 and 4 mg/kg has a limited and transient (sugammadex dose (500 mg) on the INTEM CT (P=0.002). A regression analysis showed a positive relationship between sugammadex dose and INTEM CT value at 3 min after administration (coefficient = 0.052 s; 95% CI: 0.005-0.098 s; P=0.03). No major or minor bleeding events were observed in either group during the postoperative period. Sugammadex produces a slight effect on coagulation in morbidly obese patients, without increasing the risk for postoperative bleeding.

  4. Measurement of subcutaneous adipose tissue blood flow in the morbidly obese using a laser Doppler velocimeter

    1992-08-01

    Using a laser Doppler velocimeter (LDV) subcutaneous adipose tissue blood flow (AF) was recorded in the upright and supine positions in the upper and lower abdomen in 22 morbidly obese patients before gastroplasty. Age was 42 +/- 3 (mean +/- SEM), weight 135 +/- 7 kg, and body mass index (BMI) 51 +/- 3. Adipose flow expressed as mV was: supine, upper abdomen 647 +/- 23, lower abdomen 604 +/- 24; upright, upper abdomen 621 +/- 27, lower abdomen 607 +/- 29. AF was significantly more in the upper than lower abdomen (supine position) and AF was significantly lower in the lower abdomen upright than the upper abdomen supine. Regression analysis of age indicates that blood flow decreases in the lower abdomen so that in the supine position the difference between upper and lower abdomen AF increases. Similar analysis of BMI did not indicate significant trends. These data indicate that with morbid obesity there is lower tissue blood flow to the lower abdomen. This may explain why such patients may develop areas of painful ischemic necrosis in the dependent region of their anterior abdominal pannus.

    Childhood and youth obesity represent significant US public health challenges. Recent findings that the childhood obesity ‘‘epidemic’’ may have slightly abated have been met with relief from health professionals and popular media. However, we document that the overall trend in youth obesity rates masks a significant and growing class gap between youth from upper and lower socioeconomic status (SES) backgrounds. Until 2002, obesity rates increased at similar rates for all adolescents, but sinc...

    Morbid obesity is a serious health problem whose prevalence is increasing. Expensive co-morbidities are associated to these patients, as well as a reduction in the survival. Bariatric surgery resolves the co-morbidities (type 2 diabetes mellitus, 86.6%; cardiovascular risk, 79.0%; obstructive sleep apnea syndrome, 83.6%; hypertension, 61.7%), reduces the mortality rate (among 31-40%), and increases the morbid obese patients survival over a 10-years period. It provides significant savings for the National Health System. The obese patients consume a 20% plus of health resources and 68% plus of drugs than general population. Bariatric surgery requires an initial investment (diagnosis-related group cost: 7,468 €), but it is recovered in a cost-effectiveness ratio of 2.5 years. Significant savings are obtained from the third year. To the direct economic benefits associated with reduced health expenditures it should be added an increase in tax collection (sick leave and unemployment reduction is estimated in 18%, with a productivity increase of 57% for self-employed people). Bariatric surgery is one of the most cost-effective procedures in the healthcare system. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    The aim of the present study was to elucidate the mechanisms of development of cholesterol crystals and gallstones during weight reduction in obese subjects. Twenty-five morbidly obese, gallstone-free subjects underwent vertical-banded gastroplasty. Gallbladder bile was collected at the time of the operation via needle aspiration and 1.1-7.3 months after the operation via ultrasound-guided transhepatic puncture of the gallbladder. The mean weight loss was 17 kg. Two patients developed gallstones and 10 patients displayed cholesterol crystals in their bile. In patients with a follow-up time of less than 2 months (n = 13), cholesterol saturation increased from 90% to 114% but tended to decrease in the patients with a follow-up time of more than 2 months. The extraction of the concanavalin-A-binding fraction from gallbladder bile obtained after weight reduction in 7 patients prolonged crystallization detection time from 6 to 10 days. The hexosamine concentration, a marker for mucin, was increased by about 100% in bile obtained in 6 of 7 patients after weight reduction. In conclusion, the results indicate that crystallization-promoting compounds (mucin) are of great importance in the development of cholesterol crystals and gallstones in obese subjects during weight reduction, probably because of defective gallbladder emptying.

    Full Text Available Abstract Background Prevalence of obesity is increasing to pandemic proportions. However, obese subjects differ in insulin resistance, adipokine production and co-morbidities. Based on fasting plasma analysis, obese subjects were grouped as Low Acylation Stimulating protein (ASP and Triglyceride (TG (LAT vs High ASP and TG (HAT. Subcutaneous (SC and omental (OM adipose tissues (n = 21 were analysed by microarray, and biologic pathways in lipid metabolism and inflammation were specifically examined. Methods LAT and HAT groups were matched in age, obesity, insulin, and glucose, and had similar expression of insulin-related genes (InsR, IRS-1. ASP related genes tended to be increased in the HAT group and were correlated (factor B, adipsin, complement C3, p Results HAT adipose tissue demonstrated increased lipid related genes for storage (CD36, DGAT1, DGAT2, SCD1, FASN, and LPL, lipolysis (HSL, CES1, perilipin, fatty acid binding proteins (FABP1, FABP3 and adipocyte differentiation markers (CEBPα, CEBPβ, PPARγ. By contrast, oxidation related genes were decreased (AMPK, UCP1, CPT1, FABP7. HAT subjects had increased anti-inflammatory genes TGFB1, TIMP1, TIMP3, and TIMP4 while proinflammatory PIG7 and MMP2 were also significantly increased; all genes, p Conclusion Taken together, the profile of C5L2 receptor, ASP gene expression and metabolic factors in adipose tissue from morbidly obese HAT subjects suggests a compensatory response associated with the increased plasma ASP and TG.

    The insulin-mimetic adipocytokine visfatin has been related to obesity. The aim of this study was to examine whether weight loss could change visfatin concentrations in morbidly obese patients and its relationship with insulin resistance. This was an interventional study analyzing a population of 41 morbidly obese patients. A biochemical analysis was realized before and after 2 months on a hypocaloric diet. After weight loss (average 4.41%), BMI, weight, fat mass, fat free mass, waist circumference, systolic blood pressure, serum glucose, total cholesterol, insulin and HOMA decreased. The serum concentrations of visfatin did not decrease (43.5 + 30.8 vs. 47.1 + 38.1 ng/ml). In the multivariate analysis visfatin concentrations as a dependent variable, only C reactive protein remained as an independent predictor in the model before diet, with an increase of 1.82 ng/ml (CI 95%: 0.02 - 3.61) basal visfatin concentrations with each increase of 1 mg/dl of CRP. Only HOMA remained as an independent predictor in the model after diet, with an increase of 11.4 ng/ml (CI 95%: 1.76 - 21.11) posttreatment visfatin concentrations with each increase of 1 unit HOMA. Weight reduction after a 2 months on a hypocaloric diet is not associated with a significant change in circulating visfatin in morbidly obese patients.

    Ankita Shukla

    Full Text Available OBJECTIVE: Over the past few decades, obesity has reached epidemic proportions, and is a major contributor to the global burden of chronic diseases and disability. There is little evidence on obesity related co-morbidities in BRICS countries. The first objective is to examine the factors associated with overweight and obesity in four of the five BRICS countries (China, India, Russia and South Africa. The second is to examine the linkage of obesity with selected morbidities. METHODS: We used data from the Study on Global Ageing and Adult Health (SAGE survey conducted by the World Health Organization (WHO in China, India, Russia and South Africa during 2007-10. The morbidities included in the analysis are Hypertension, Diabetes, Angina, Stroke, Arthritis and Depression. FINDINGS: The prevalence of obesity was highest in South Africa (35% followed by Russia (22%, China (5% and India (3%. The prevalence of obesity was significantly higher in females as compared to males in all the countries. While the wealth quintile was associated with overweight in India and China, engaging in work requiring physical activity was associated with obesity in China and South Africa. Overweight/obesity was positively associated with Hypertension and Diabetes in all the four countries. Obesity was also positively associated with Arthritis and Angina in China, Russia and South Africa. In comparison, overweight/obesity was not associated with Stroke and Depression in any of the four countries. CONCLUSION: Obesity was statistically associated with Hypertension, Angina, Diabetes and Arthritis in China, Russia and South Africa. In India, obesity was associated only with Hypertension and Diabetes.

Research generally indicates that persons with morbid obesity increase their HRQoL following intervention, whereas evidence of increases in HRQoL in persons with COPD is mixed. Examining the patterns of change over time instead of merely examining whether HRQoL changes will add to the knowledge in this field.Methods: A sample of persons with morbid obesity and persons with COPD was recruited from learning and mastery courses and rehabilitation centers in Norway. The data were collected by self-report questionnaires at the start of patient education and at four subsequent time points during the 1-year follow-up. HRQoL was measured with the Short Form 12, version 2, and repeated measures analysis of variance was employed in the statistical analysis.Results: Participants with morbid obesity linearly increased their physical HRQoL during the 1-year follow-up, whereas participants with COPD showed no change. None of the groups changed their mental HRQoL during follow-up. In all subdomains of HRQoL, the participants with morbid obesity showed favorable, linearly increasing trajectories across the follow-up period. Among the participants with COPD, no change patterns occurred in the subdomains of HRQoL, except for a fluctuating pattern in the mental health domain. Age, sex, and work status did not influence the trajectories of HRQoL in any of the domains.Conclusion: A more favorable trajectory

    Morbidly obesity is characterized by physical and psychological comorbidities which are associated with reduced quality of life. Bariatric surgery has been linked to a reduction of psychopathology other than to a reduction of weight and improvement in physical functioning. Aim of the present study was to compare psychological features of two groups of morbidly obese patients, before and after bariatric surgery, assessing social phobia and quality of life. A total of 46 morbidly obese patients were enrolled in the study. Of them, 20 were waiting for bilio-pancreatic diversion (group A), while 26 had already undergone surgical procedure (group B). Psychometric evaluation assessed social phobia, fear for the body-shape and quality of life, using appropriate psychometric tests. The percentage of patients showing social phobia was significantly higher compared to a sample of healthy controls (p=0.004), both in group A (p=0.003) and in group B (p=0.029). No differences in percentage of patients affected by social phobia were found between groups. A significantly higher percentage of patients affected by distress about the body (psocial phobia in a population of morbidly obese patients, both before and after surgery. A general reduction of quality of life was also observed, with a partial improvement after surgery. Future studies are needed to clarify the relationship between social phobia and quality of life in surgically-treated morbidly obese patients. Copyright © 2015 Elsevier B.V. All rights reserved.

    2015-04-01

    Morbid obesity is a highly prevalent condition that is associated with a high risk of various diseases and high health care costs. Understanding determinants of eating behaviours that are characteristic of many morbidly obese persons is important for the development of new interventions aimed at changing eating behaviour after bariatric surgery. Dispositional mindfulness seems promising as one such potential determinant. Therefore, the association between mindfulness and eating behaviour was examined in females and males with morbid obesity. Outpatients with morbid obesity who were candidates for bariatric surgery (N = 335; 78.8% female) completed the Dutch Eating Behaviour Questionnaire (DEBQ), the Freiburg Mindfulness Inventory (FMI) and the Hospital Anxiety and Depression Scale (HADS), in addition to the collection of relevant demographic and medical data. Three separate multiple regression analyses with three eating behaviour styles (restrained, emotional, external) as dependent variables showed that mindfulness was positively associated with restrained eating behaviour (Beta = .28, p ≤ .001), and negatively associated with emotional (Beta = -.22, p ≤ .001) and external (Beta = -.32, p ≤ .001) eating behaviours, independent of sex, age, educational level, Body Mass Index and affective symptoms. Dispositional mindfulness was associated with more restrained, and less emotional and external eating behaviour in morbidly obese outpatients, above and beyond affective symptoms. Future studies, establishing the causal direction of the associations, are needed. Copyright © 2014 Elsevier Ltd. All rights reserved.

U.S. counties (448) and metropolitan areas (83). Adults (n = 206,992) from pooled 1998, 1999, and 2000 Behavioral Risk Factor Surveillance System (BRFSS). Sprawl indices, derived with principal components analysis from census and other data, served as independent variables. Self-reported behavior and health status from BRFSS served as dependent variables. After controlling for demographic and behavioral covariates, the county sprawl index had small but significant associations with minutes walked (p = .004), obesity (p sprawling counties were likely to walk less during leisure time, weigh more, and have greater prevalence of hypertension than residents of compact counties. At the metropolitan level, sprawl was similarly associated with minutes walked (p = .04) but not with the other variables. This ecologic study reveals that urban form could be significantly associated with some forms of physical activity and some health outcomes. More research is needed to refine measures of urban form, improve measures of physical activity, and control for other individual and environmental influences on physical activity, obesity, and related health outcomes.

    Pathologic changes in the liver are common in morbidly obese patients, and insulin resistance may potentiate the progression of nonalcoholic steatohepatitis to fibrosis and cirrhosis. This study investigates the impact of leptin and adiponectin in morbidly obese diabetic and nondiabetic patients with regard to histopathologic changes in the liver. Thirty-seven morbidly obese patients who underwent bariatric surgery with liver biopsies were enrolled in the study. Fourteen were diabetic and 23 were nondiabetic. Intraoperative liver tissue was sent for histopathologic analysis and extraneous intraoperative tissue was snap-frozen in liquid nitrogen. Total RNA was extracted and RNA was reverse transcribed to cDNA. Real-time quantitative PCR was performed to determine relative gene expression levels. The data were analyzed using a logarithmic transformation and normalized by 18S ribosome expression. Student's t test was used for statistical analysis with p < or = 0.05 as significant. Adiponectin expression was downregulated 4.4-fold (p < or = 0.05) in liver samples with evidence of inflammation on pathology. When hepatic inflammation was evaluated separately, there were no statistically significant differences in adiponectin levels between the diabetic and nondiabetic patients. However, overall adiponectin levels in hepatic samples of diabetic patients were 3.8-fold higher than those of nondiabetic patients (p < or = 0.05). There were no significant differences in leptin levels regardless of hepatic pathology or diabetic status. This study illustrates that there is a downregulation of adiponectin in morbidly obese patients with inflammatory infiltrates in the liver. Variations in adiponectin levels could be an indicator of disease progression since inflammatory infiltrates are commonly associated with nonalcoholic steatohepatitis (NASH) in morbidly obese patients. Currently, we are using human myofibroblasts derived from livers of morbidly obese people to further

    Full Text Available Introduction: morbid obesity (MO is a chronic disease that is reaching epidemic proportions and becoming an increasing health problem in developed countries. Obesity-related comorbidities reduce both the quality and expectancy of life. Objectives: to validate the GIQLI (Gastrointestinal Quality of Life Index test as a reliable and effective tool for the evaluation of quality of life in morbidly obese patients. Patients and methods: the GIQLI test is made up of 36 individually scored items, the addition of which give up a final score. A higher score correlates with a better quality of life. Items can be separated into five groups or dimensions: digestive symptoms, emotional status, effects of treatment, and physical as well as social dysfunction. The GIQLI test was administered to a randomized sample of 1990 morbidly obese patients who fulfilled the indication criteria for bariatric surgery, and to a control group of 100 healthy individuals with no known medical, functional or psychiatric disease. Overall test and specific dimension scores were evaluated for each group. Results: overall test and specific dimension scores were significantly lower in patients with MO when compared to the control group. The overall GIQLI score decreased as age increased, as did the number of associated comorbidities. Conclusions: the GIQLI test proved to be a rather useful tool to evaluate quality of life in morbidly obese patients. These patients present a poorer quality of life not only because of the presence of digestive symptoms but also because of their emotional, physical, and social status.Introducción: la obesidad mórbida (OM es una enfermedad crónica que alcanza dimensiones epidémicas en los países desarrollados.

    Morbid obesity is a significant clinical problem in the western world. Various surgical restrictive procedures have been described as an aid to weight reduction when conservative treatments fail. Adjustable laparoscopic gastric banding (LAPBAND) has been popularized as an effective, safe, minimally invasive, yet reversible technique for the treatment of morbid obesity. Radiological input is necessary in the follow-up of these patients and the diagnosis of complications peculiar to this type of surgery. In this review we will highlight the technical aspects of radiological follow-up and the lessons learnt over the last 5 years.

    The aim of this study was to evaluate potential risk factors, including non-communicable diseases, for morbid obesity in women between 20 and 49 years of age. We performed a case-control study with 110 morbidly obese women and 110 women with adequate weight who were matched by age and with a 1:1 case to control ratio. All women were between 20 to 49 years old and non-menopausal. Possible risk factors were evaluated through a self-report questionnaire assessing socio-demographic, obstetric and gynecological characteristics, presence of non-communicable diseases and habits. Multiple logistic regression was used to estimate the odds ratio with respective confidence intervals. Menarche under 12 years old, teenage pregnancy and lower educational level were shown to be risk factors for morbid obesity among women of reproductive age. Incidences of non-communicable diseases (diabetes, hypertension, dyslipidemia, liver disease, lung disease, thyroid dysfunction, and joint pain) were increased in women with morbid obesity. Early menarche, teenage pregnancy and low education level are risk factors for the occurrence of morbid obesity in women of reproductive age. Some non-communicable diseases were already more prevalent in women with morbid obesity even before 50 years of age.

    Its indications should only be considered in patients with morbid obesity (BMI>40 kg/m2) or severe obesity (BMI>35 kg/m2) with serious associated comorbidity. In general, significant weight loss with marked improvement of the cardiovascular comorbidity is obtained. There are still no studies that show long term survival. It must be stressed that the patients should follow a subsequent and continuous medical monitoring to prevent important secondary metabolic complications.

    The aim of our study was to assess midurethral sling (MUS) failure rate in the morbidly obese (body mass index [BMI] ≥40 kg/m) population as compared with normal-weight individuals. Our secondary objective was to assess the difference in complication rates. This is a retrospective cohort study. We included all patients who underwent a synthetic MUS procedure from January 1, 2008, to December 31, 2015, in our health system. Failure was defined as reported stress urinary incontinence symptoms or treatment for stress urinary incontinence. Variables collected were BMI; smoking status; comorbidities; perioperative (≤24 hours), short-term (≤30 days), and long-term (>30 days) complications; and follow-up time. Statistics include analysis of variance, χ test, logistic regression, Kaplan-Meier method, and Cox regression. There were 431 patients included in our analysis. Forty-nine patients were in class 3 with a BMI mean of 44.9 ± 5.07 kg/m. Median follow-up time was 52 months (range, 6-119 months). Class 3 obesity (BMI ≥40 kg/m) was the only group that had an increased risk of failure when compared with the normal-weight group (P = 0.03; odds ratio, 2.47; 95% confidence interval, 1.09-5.59). Obesity was not a significant predictor of perioperative, short-term, or long-term postoperative complications (P = 0.19, P = 0.28, and P = 0.089, respectively) after controlling for other comorbidities. Patients in the class 3 obesity group who are treated with an MUS are 2 times as likely to fail when compared with those in the normal-weight category on long-term follow-up with similar low complication rates.

    Both morbid obesity and binge eating disorder (BED) have previously been linked with aberrant brain opioid function. Behaviorally these two conditions are however different suggesting also differences in neurotransmitter function. Here we directly compared mu-opioid receptor (MOR) availability between morbidly obese and BED subjects. Seven BED and nineteen morbidly obese (non-BED) patients, and thirty matched control subjects underwent positron emission tomography (PET) with MOR-specific ligand [ 11 C]carfentanil. Both subjects with morbid obesity and BED had widespread reduction in [ 11 C]carfentanil binding compared to control subjects. However, there was no significant difference in brain MOR binding between subjects with morbid obesity and BED. Thus, our results indicate that there is common brain opioid abnormality in behaviorally different eating disorders involving obesity. Copyright © 2018 Elsevier B.V. All rights reserved.

  8. Managing social awkwardness when caring for morbidly obese patients in intensive care: A focused ethnography.

    Hales, Caz; de Vries, Kay; Coombs, Maureen

    2016-06-01

    Critically ill morbidly obese patients pose considerable healthcare delivery and resource utilisation challenges in the intensive care setting. These are resultant from specific physiological responses to critical illness in this population and the nature of the interventional therapies used in the intensive care environment. An additional challenge arises for this population when considering the social stigma that is attached to being obese. Intensive care staff therefore not only attend to the physical and care needs of the critically ill morbidly obese patient but also navigate, both personally and professionally, the social terrain of stigma when providing care. To explore the culture and influences on doctors and nurses within the intensive care setting when caring for critically ill morbidly obese patients. A focused ethnographic approach was adopted to elicit the 'situated' experiences of caring for critically ill morbidly obese patients from the perspectives of intensive care staff. Participant observation of care practices and interviews with intensive care staff were undertaken over a four month period. Analysis was conducted using constant comparison technique to compare incidents applicable to each theme. An 18 bedded tertiary intensive care unit in New Zealand. Sixty-seven intensive care nurses and 13 intensive care doctors involved with the care and management of seven critically ill patients with a body mass index ≥40kg/m(2). Interactions between intensive care staff and morbidly obese patients were challenging due to the social stigma surrounding obesity. Social awkwardness and managing socially awkward moments were evident when caring for morbidly obese patients. Intensive care staff used strategies of face-work and mutual pretence to alleviate feelings of discomfort when engaged in aspects of care and caring. This was a strategy used to prevent embarrassment and distress for both the patients and staff. This study has brought new understandings

    2008-12-01

    Morbidly obese men may have poorer pulmonary gas exchange compared to morbidly obese women (see Zavorsky et al., Chest 131:362-367, 2007). The purpose was to compare pulmonary gas exchange in morbidly obese men and women at rest and throughout exercise. Twenty-five women (age=38+/-10 years, 164+/-7 cm, body mass index or BMI = 51+/-7 kg/m(2), peak oxygen consumption or VO(2peak)=2.0+/-0.4 l/min) and 17 men (age=43+/-9 years, 178+/-7 cm, BMI=50+/-10 kg/m(2), VO(2peak)=2.6+/-0.8 l/min) were recruited to perform a graded exercise test on a cycle ergometer with temperature-corrected arterial blood-gas samples taken at rest and every minute of exercise, including peak exercise. At rest, women were 98% predicted for pulmonary diffusion compared to 88% predicted in men. At rest, women had better pulmonary gas exchange compared to the men which was related to women having a lower waist-to-hip ratio (WHR; por=25 mmHg) at peak exercise, but 75% of the subjects showed inadequate compensatory hyperventilation at peak exercise (arterial carbon dioxide pressure >35 mmHg), and both were not different between genders. At rest, morbidly obese men have poorer pulmonary gas exchange and pulmonary diffusion compared to morbidly obese women. The better gas exchange in women is related to the lower WHR in the women. During exercise, few subjects showed disturbances in pulmonary gas exchange despite demonstrating poor compensatory hyperventilation at peak exercise.

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

    Overweight and obesity are ranked in the fifth place among the risk factors responsible for the greatest number of deaths in the world. To assess the effects of treatment of patients with morbid obesity using endoscopic intragastric balloon (IGB) implantation. Two hundred and seventy-two patients with obesity were treated using endoscopic intragastric balloon implantation. Upon analysis of the inclusion and exclusion criteria, the study covered a group of 63 patients with morbid obesity. The patients were implanted with the LexBal balloon. Reduction of excess body mass, changes to BMI values and ailments and complications divided into mild and severe were assessed. Before intragastric balloon treatment, the average body mass index (BMI) value was 58.3 ±10.5 kg/m 2 , whereas after 6 months of treatment it decreased to 49.5 ±8.7 kg/m 2 . The patients with postoperative BMI equal to or greater than 50.0 kg/m 2 reported nausea (69.7%), vomiting (51.5%), flatulence (45.5%), upper abdominal pain (36.4%) and general discomfort (424%) more frequently. Dehydration (9.1%) was also more frequent in this group, whereas frequency of occurrence of such ailments and complications as heartburn (23.3%) and oesophageal candidiasis (10.0%) was higher in the patients with postoperative BMI below 50.0 kg/m 2 . Endoscopic intragastric balloon implantation is an effective and safe method of excess body mass reduction in patients with morbid obesity before a planned bariatric surgical procedure. Pre-operative excess body mass and BMI value and post-operative excess weight loss in patients with morbid obesity have no impact on frequency of occurrence of ailments and complications in IGB treatment.

    The current obesity epidemic is attributed to complex interactions between genetic and environmental factors. However, a limited number of cases, especially those with early-onset severe obesity, are linked to single gene defects. Rapid-onset obesity with hypothalamic dysfunction, hypoventilation and autonomic dysregulation (ROHHAD) is one of the syndromes that presents with abrupt-onset extreme weight gain with an unknown genetic basis. To identify the underlying genetic etiology in a child with morbid early-onset obesity, hypoventilation, and autonomic and behavioral disturbances who was clinically diagnosed with ROHHAD syndrome. Design/Setting/Intervention: The index patient was evaluated at an academic medical center. Whole-exome sequencing was performed on the proband and his parents. Genetic variants were validated by Sanger sequencing. We identified a novel de novo nonsense mutation, c.3265 C>T (p.R1089X), in the retinoic acid-induced 1 (RAI1) gene in the proband. Mutations in the RAI1 gene are known to cause Smith-Magenis syndrome (SMS). On further evaluation, his clinical features were not typical of either SMS or ROHHAD syndrome. This study identifies a de novo RAI1 mutation in a child with morbid obesity and a clinical diagnosis of ROHHAD syndrome. Although extreme early-onset obesity, autonomic disturbances, and hypoventilation are present in ROHHAD, several of the clinical findings are consistent with SMS. This case highlights the challenges in the diagnosis of ROHHAD syndrome and its potential overlap with SMS. We also propose RAI1 as a candidate gene for children with morbid obesity.

    We aimed to evaluate the effect of health literacy on agreement for bariatric surgery among morbidly obese patients. The data of 242 morbidly obese patients (body mass index-BMI ≥ 40 kg/m 2 ) were evaluated in a cross-sectional case-control pattern. The patients were classified into two groups as those who were attending the clinic for the purpose of receiving bariatric surgery (n = 138) and those who did not (n = 104). The Turkish version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47), consisting of 47 questions, was used for the health literacy evaluation. It was seen that patients who accepted bariatric surgery were younger and had higher weight and BMI values (p bariatric surgery and 26.04 (8.33:46.88) in the group who did not agree to bariatric surgery, and a statistically significant difference was determined between the two groups (p bariatric surgery and 45.2% of the group who did not (p  25-33) (respectively, 36.2%, 37.5%, p = 0.840). A sufficient level (> 33-42) and a perfect level were higher in the group who agreed to bariatric surgery (respectively, 42.8%, 18.1%, p bariatric surgery in morbidly obese patients. The higher the health literacy level, the more the agreement to bariatric surgery increased.

    Economic development is known to shift the distribution of obesity from the socioeconomically more advantaged to the less advantaged. We assessed the socioeconomic trends in overweight, obesity, and abdominal obesity across a period of significant economic growth. We used the Malaysian National Health and Morbidity Survey data sets for the years 1996, 2006, and 2011 to analyze the trends among adults aged 30 years and above. The World Health Organization's Asian body mass index cut-off points of ≥23.0 kg/m 2 and ≥27.5 kg/m 2 were used to define overweight and obesity, respectively. Abdominal obesity was defined as having a waist circumference of ≥90 cm for men and ≥80 cm for women. Household per-capita income was used as a measure of socioeconomic position. As a summary measure of inequality, we computed the concentration index. Women in Peninsular Malaysia demonstrated patterns that were similar to that of developed countries in which the distributions for overweight, obesity, and abdominal obesity became concentrated among the poor. For women in East Malaysia, distributions became neither concentrated among the rich nor poor, while distributions for men were still concentrated among the rich. Chinese women, particularly from the richest quintile, had the lowest rates and lowest increase in overweight and obesity. All distributions of Chinese women were concentrated among the poor. The distributions of Malay men were still concentrated among the rich, while distributions for Chinese and Indian men and Malay and Indian women were neither concentrated among the rich nor poor. As the country continues to progress, increasing risks of overweight and obesity among the socioeconomically less advantaged is expected.

    2013-12-01

    Full Text Available Background/Aims: To determine i whether obesity in childhood can be related to malalignment of the distal extremities, ii the proportion of genu valgum malalignment and abduction setting, and iii the respective deviation dominance in children who are morbidly obese. Methods: 31 morbidly obese Caucasian children (16 males recruited for the STYJOBS Study (ClinicalTrials.gov Identifier NCT00482924 with a mean age of 13.9 ± 0.5 years, a mean height of 162.3 ± 2.7 cm, a mean weight of 90.62 ± 5.0 kg, and a mean BMI of 33.8 ± 1.2 kg/m2 were clinically examined using the Mikulicz line in order to assess load distribution on the knee joint. 21 participants received a whole-leg X-ray because of a clinically estimated malalignment. Results: 8/31 participants examined were diagnosed with genu valgum, 1/31 with genu varum, and 22/31 did not have any malalignment of the femur or tibia. The majority of genu valgum presentation was due to femoral deviation. Of those without malalignment, 4/22 participants had an abduction setting, while 2/22 showed an adduction of the leg. Conclusion: Genu valgum as a predominant malalignment of the distal extremities is frequent in youth with morbid obesity. Timely guided correction of angular deformity of the knee seems pivotal in order to avoid osteotomy or osteoarthritis later in life.

    Morbid obesity is associated with debilitating psychosocial consequences, such as depression, anxiety, and low self-esteem. One of the main goals of bariatric surgery should not only be reducing weight and counteracting co-morbid conditions, but also improving postoperative psychosocial functioning. The objective of our study was to determine the preoperative variables that could predict the psychological symptoms 6 and 12 months after surgery to improve the clinical outcome of morbidly obese patients undergoing bariatric surgery. The setting was a university hospital in Spain. The study group consisted of 60 morbidly obese patients (46 women and 14 men) who had undergone gastric bypass surgery for weight reduction and had ≥ 1 year of follow-up. The patients were evaluated using different questionnaires (Symptom Checklist-90-Revised, Body Shape Questionnaire, Rosenberg Self-Esteem Questionnaire, COPE, Medical Outcomes Study Social Support Survey) at 3 points: before surgery, at 6 months postoperatively, and at 1 year postoperatively. To determine the influence of preoperative variables on long-term psychological status, a step-by-step multivariate linear regression analysis was performed, taking P self-esteem, instrumental support, and coping focused in the emotions were the main preoperative predictors for psychological symptoms 6 months after surgery. Preoperative drug abuse as a strategy of problem solving and mainly body image significantly predicted most of the psychological disorders 1 year after surgery. The study of different psychosocial variables in patients before bariatric surgery is an important aid to predict postoperative psychological functioning. Self-esteem and body image were the most influential factors in the postoperative psychological outcome of morbidly obese patients in our study.

    2016-01-01

    Full Text Available Morbidly obese patients with clinical features of obstructive sleep apnoea can present a myriad of challenges to the anaesthesiologists which must be addressed to minimise the perioperative risks. Initiation of continuous positive airway pressure (CPAP therapy early in the pre- and post-operative period along with appropriate anaesthetic planning is of paramount importance in such patients. This case report emphasises the usefulness of CPAP therapy, even for a short duration, to minimise morbidity, improve recovery and hasten early discharge from the hospital after major surgery.

    Laparoscopic mini-gastric bypass surgery is a safe and simple surgical intervention for treating morbid obesity and diabetes mellitus and is now being performed more frequently. Radiologists must be critical in their postoperative evaluation of these patients. In this pictorial review, we explain and illustrate the surgical technique, normal postoperative anatomy, and associated complications as seen on imaging examinations, including fluoroscopy and computed tomography.

    2018-01-01

    Full Text Available Background: Since studies have demonstrated that morbid obesity can exponentially impair quality of life, the measurement of quality of life is paramount to monitoring the effects of treatment and influences the development of clinical pathways, service provision, healthcare expenditures, and public health policy. Accordingly, clinicians, researchers, and policy makers must rely on valid instruments. Aim: This study aimed to review and critique the psychometric properties of some specific tools by COSMIN checklist and their application among morbidly obese individuals. Method: We searched PubMed, Web of Science, PsycINFO, Ovid, Elsevier, and ScienceDirect by using the keywords related to the Quality of Life Questionnaire, namely “morbid obesity”, “tool”, and “scale”, to retrieve articles published during 1989-2017. Then, the psychometric properties of the selected tools were assessed using the COSMIN checklist. Results: Most of the tools had not reported complete and desirable psychometrics properties. Demonstration of responsiveness from independent randomized controlled trials was not available in two of the eight questionnaires. These tools also did not report proper definition of interpretability. However, the data obtained by COSMIN checklist showed that Laval questionnaire is a proper scale for measuring quality of life in obese individuals, which can be recommended to researchers. Implications for Practice: Although Laval questionnaire was found a proper tool for measuring the quality of life among morbid obese patients, developing an instrument suitable for different societies with varied cultural and social characteristics is suggested because socio-cultural factors can influence the quality of life.

    Obesity is a multifactorial disorder often associated with many important diseases such as diabetes, hypertension and other metabolic syndrome conditions. Argyrophil cells represent almost the total population of endocrine cells of the human gastric mucosa and some reports have described changes of specific types of these cells in patients with obesity and metabolic syndrome. The present study was designed to evaluate the global population of argyrophil cells of the gastric mucosa of morbidly obese and dyspeptic non-obese patients. Gastric biopsies of antropyloric and oxyntic mucosa were obtained from 50 morbidly obese patients (BMI >40) and 50 non-obese patients (17 dyspeptic overweight and 33 lean individuals) and processed for histology and Grimelius staining for argyrophil cell demonstration. Argyrophil cell density in the oxyntic mucosa of morbidly obese patients was higher in female (238.68 ± 83.71 cells/mm 2 ) than in male patients (179.31 ± 85.96 cells/mm 2 ) and also higher in female (214.20 ± 50.38 cells/mm 2 ) than in male (141.90 ± 61.22 cells/mm 2 ) morbidly obese patients with metabolic syndrome (P = 0.01 and P = 0.02, respectively). In antropyloric mucosa, the main difference in argyrophil cell density was observed between female morbidly obese patients with (167.00 ± 69.30 cells/mm 2 ) and without (234.00 ± 69.54 cells/mm 2 ) metabolic syndrome (P = 0.001). In conclusion, the present results show that the number of gastric argyrophil cells could be under gender influence in patients with morbid obesity. In addition, gastric argyrophil cells seem to behave differently among female morbidly obese patients with and without metabolic syndrome

  13. Understanding everyday life of morbidly obese adults-habits and body image

    Bjørg Christiansen

    2012-07-01

    Full Text Available Background: Morbid obesity is a progressive, chronic condition associated with failed attempts at change and repeated relapses. Aim: There seems to be little previous research into the understanding of the everyday life of morbidly obese adults. We wanted to gain more knowledge about characteristics of eating habits and body image as well as motivational forces for change. Methods: A qualitative approach was chosen in order to gain insight into how morbidly obese adults experience everyday life. Qualitative interviews are well suited to provide insight into themes from the interviewee's life story from the subjects’ own perspectives. To gain insight into such processes, a narrative approach that allowed the informants to give voice to their ways of doing, thinking and feeling in daily life, was adopted. The informants comprised seven women and four men aged of 26–56 years, recruited from a population of obese individuals who had participated in a weight reduction course. A hermeneutic approach was used where the research question was the basis for a reflective interpretation. Results: The following meaning-units were identified: to be perceived as overweight; and to see oneself as overweight. Ingrained habits: the struggle between knowing and doing; acting without knowing; and eating is soothing. Conclusions: Seeing oneself as an obese person is a gradual process that implied experiencing oneself as different from significant others, such as (slim siblings and friends. To experience a gap between knowing and doing concerning food habits in everyday life indicates that informants value they have a choice. This is an important insight to consider when framing interventions to support this vulnerable group.

  14. Perioperative management of a morbidly obese pregnant patient undergoing cesarean section under general anesthesia - case report

    Márcio Luiz Benevides

    Full Text Available Abstract Background and objectives: The increased prevalence of obesity in the general population extends to women of reproductive age. The aim of this study is to report the perioperative management of a morbidly obese pregnant woman, body mass index >50 kg/m2, who underwent cesarean section under general anesthesia. Case report: Pregnant woman in labor, 35 years of age, body mass index 59.8 kg/m2. Cesarean section was indicated due to the presumed fetal macrosomia. The patient refused spinal anesthesia. She was placed in the ramp position with cushions from back to head to facilitate tracheal intubation. Another cushion was placed on top of the right gluteus to create an angle of approximately 15° to the operating table. Immediately before induction of anesthesia, asepsis was carried out and sterile surgical fields were placed. Anesthesia was induced in rapid sequence, with Sellick maneuver and administration of remifentanil, propofol, and succinilcolina. Intubation was performed using a gum elastic bougie, and anesthesia was maintained with sevoflurane and remifentanil. The interval between skin incision and fetal extraction was 21 min, with the use of a Simpson's forceps scoop to assist in the extraction. The patient gave birth to a newborn weighing 4850 g, with Apgar scores of 2 in the 1st minute (received positive pressure ventilation by mask for about 2 min and 8 in the 5th minute. The patient was extubated uneventfully. Multimodal analgesia and prophylaxis of nausea and vomiting was performed. Mother and newborn were discharged on the 4th postoperative day.

    2017-04-01

    Full Text Available Background Reduction of readmissions after discharge represents an important challenge for many hospitals and has attracted the interest of many researchers in the past few years. Most of the studies in this field focus on building cross-sectional predictive models that aim to predict the occurrence of readmission within 30-days based on information from the current hospitalization. The aim of this study is demonstration of predictive performance gain obtained by inclusion of information from historical hospitalization records among morbidly obese patients. Methods The California Statewide inpatient database was used to build regularized logistic regression models for prediction of readmission in morbidly obese patients (n = 18,881. Temporal features were extracted from historical patient hospitalization records in a one-year timeframe. Five different datasets of patients were prepared based on the number of available hospitalizations per patient. Sample size of the five datasets ranged from 4,787 patients with more than five hospitalizations to 20,521 patients with at least two hospitalization records in one year. A 10-fold cross validation was repeted 100 times to assess the variability of the results. Additionally, random forest and extreme gradient boosting were used to confirm the results. Results Area under the ROC curve increased significantly when including information from up to three historical records on all datasets. The inclusion of more than three historical records was not efficient. Similar results can be observed for Brier score and PPV value. The number of selected predictors corresponded to the complexity of the dataset ranging from an average of 29.50 selected features on the smallest dataset to 184.96 on the largest dataset based on 100 repetitions of 10-fold cross-validation. Discussion The results show positive influence of adding information from historical hospitalization records on predictive performance using all

    Bariatric surgery is currently the most effective therapy to induce weight loss in morbidly obese patients. Objective. This controlled, clinical trial with a two-year intervention was aimed at comparing the efficacy of two nonsurgical approaches versus bariatric surgery, on body weight changes and metabolic parameters in morbidly obese patients. Methods. Patients were randomized to an Intensive Lifestyle Intervention (ILI) (n = 60) or Conventional Obesity Therapy (COT) (n = 46). The ILI group received behavioral therapy and nutritional counseling. The COT group received standard medical treatment. They were compared with a third group, Surgical Obesity Group (SOG) (n = 37). Results. Patients who received ILI had a greater percentage of weight loss than patients receiving COT (−11.3% versus −1.6%; p < 0.0044). Interestingly 31.4% of patients included in the ILI group were no longer morbidly obese after just six months of intervention, increasing to 44.4% after 24 months of intervention. The percentage weight loss in SOG was −29.6% after that same period of time. Conclusions. ILI was associated with significant weight loss when compared to COT, in a group of patients with obesity. An ILI approach could be an alternative therapy to patients with obesity, who are not candidates to undergo bariatric surgery. This trial is registered with EudraCT 2009-013737-24. PMID:26257780

    Background Proglucagon-derived hormones represent a family of peptides mainly produced in the pancreas and the intestine. While several proglucagon-derived peptides play key roles in metabolic diseases, little is known about glicentin. The aim of the present study was to investigate serum glicentin concentrations in individuals with adult obesity and to study its potential link with various metabolic parameters. Methods Fifty-two individuals with normal body mass index (BMI  35 kg/m 2 ) were prospectively included at the University Hospital of Nice between January 2014 and April 2016. Clinical data were recorded, and a fasting blood sample was collected to measure glicentin, glucose, insulin, C-peptide, total cholesterol, triglyceride, LDL and HDL-cholesterol. In addition, a homeostasis model assessment for insulin resistance (HOMA2-IR) was also calculated. Results Patients with severe and morbid obesity had significantly higher plasma glucose, together with higher serum concentrations of insulin, C-peptide, HOMA2-IR, triglyceride, LDL-cholesterol and lower serum concentrations of HDL-cholesterol compared with individuals with a normal body mass index. The obese patients displayed significantly lower fasting serum concentrations of glicentin compared with subjects with a normal body mass index (12 pmol/L vs. 24 pmol/L, P < 0.0001). In the total population, fasting glicentin concentrations did not correlate with BMI, glycaemic parameters (glucose, insulin, C-peptide, HOMA-IR) or lipid parameters (total cholesterol, triglyceride, LDL and HDL-cholesterol). Conclusion To the best of our knowledge, this is the first study reporting serum glicentin concentrations in healthy lean and obese adult subjects. We found that fasting serum glicentin concentrations are decreased in patients with severe or morbid obesity suggesting the potential interest of this peptide in obesity and metabolic-related disorders.

    Sex hormone-binding globulin (SHBG) binds and transports testosterone and estradiol in plasma. The possibility that SHBG is a mixture of transporting proteins has been postulated. We analyzed in parallel the effects of obesity status on the levels and binding capacity of circulating SHBG and their relationship with testosterone and estradiol. Anthropometric measures and plasma were obtained from apparently healthy young (i.e. 35 ± 7 years) premenopausal women ( n =  32) and men ( n =  30), with normal weight and obesity (BMI >30 kg/m 2 ). SHBG protein (Western blot), as well as the plasma levels of testosterone, estradiol, cortisol and insulin (ELISA) were measured. Specific binding of estradiol and testosterone to plasma SHBG was analyzed using tritium-labeled hormones. Significant differences in SHBG were observed within the obesity status and gender, with discordant patterns of change in testosterone and estradiol. In men, testosterone occupied most of the binding sites. Estrogen binding was much lower in all subjects. Lower SHBG of morbidly obese (BMI >40 kg/m 2 ) subjects affected testosterone but not estradiol. The ratio of binding sites to SHBG protein levels was constant for testosterone, but not for estradiol. The influence of gender was maximal in morbid obesity, with men showing the highest binding / SHBG ratios. The results reported here are compatible with SHBG being a mixture of at least two functionally different hormone-binding globulins, being affected by obesity and gender and showing different structure, affinities for testosterone and estradiol and also different immunoreactivity. © 2017 European Society of Endocrinology.

    The federal government, the medical insurance industry, and the academic medical community have disagreed over what treatments are appropriate and cost effective for morbid obesity. This debate is hindered by inadequate data regarding the true costs of diseases and who chooses an operation as a treatment option. The purpose of this study was to obtain these costs and to describe this population. Louisiana's managed medical insurance program created primarily for its civil service employees contracted to offer a small random group of morbidly obese employees the option of a bariatric operation. This observational study examined the subpopulation who requested consideration for the operation. We present historic cost data from all medical expenses paid by the insurance company, a telephone survey of the volunteers in the study to determine their medical problems, and diagnostic evaluation data on those employees randomized to proceed for possible bariatric operation. A total of 911 of 189,398 adult members of the insurance plan wanted to be considered for this study. Only 397, however, completed the informed-consent process. Of the 248 employees who met the age requirement, body mass index criteria, and health criteria to be considered for a bariatric operation and were randomized, 20 withdrew before obtaining 40 committed operative candidates. The 773 morbidly obese female members had used a mean of dollar 11,145 in medical insurance expenses in the year 2003 versus a mean of dollar 8,096 for the other 106,908 adult women. Similar values for the men were dollar 16,720 for the 138 morbidly obese men versus dollar 5,943 for the other 82,490 men. The morbidly obese members of this medical insurance plan who requested a bariatric operation are costing their plan 1.4 to 2.8 times the yearly amount of the other adult members in medical expenses. The yearly mean amount the insurance plan spends on these members suggests that operative treatment would pay for itself in a

    Overweight and obesity are growing health problems both worldwide and in Malaysia due to such lifestyle changes as decreased physical activity (PA), increased sedentary behavior and unhealthy eating habits. This study examined the levels and patterns of PA among normal-weight and overweight/obese adults and to investigate the association between PA level and overweight/obesity in Malaysian adults. This study used data from the 2015 National Health and Morbidity Survey (NHMS), a nationwide cross-sectional survey that implemented a two-stage stratified random sampling design. Respondents aged 18 years and above (n = 17,261) were included in the analysis. The short version of International Physical Activity Questionnaire (IPAQ) was administered to assess the respondents' PA levels. The respondents' height and weight were objectively measured and body mass index (BMI) was calculated. The respondents were categorized according to BMI as either normal-weight (18.5-24.9 kg/m 2 ) or overweight/obese (≥ 25 kg/m 2 ). Descriptive and complex sample logistic regression analyses were employed as appropriate. Overall, approximately 1 in 2 respondents (51.2%) were overweight/obese, even though the majority (69.0%) reporting at least a moderate level of PA (total PA ≥ 10 MET-hours/week). In both normal-weight and overweight/obese groups, a significantly higher prevalence of high PA (total PA ≥ 50 MET-hours/week) was observed among men than women (p obese men reported a significantly lower level of vigorous-intensity PA and total PA than normal-weight men (p obesity (Adjusted OR = 1.14; 95% CI: 1.01-1.30) compared to a high level of PA among men but not among women. The levels of PA were inversely related to the risk of overweight/obesity in men but not in women. Programs designed to reduce overweight/obesity rates should encourage the practice of moderate- to vigorous-intensity PA. Future research should consider using longitudinal and prospective

    Vitamin D deficiency is a common issue, particularly in obese populations, and is tested by assessing serum 25(OH)D concentrations. This study aimed to identify factors that contribute to the vitamin D status in fifty morbidly obese individuals recruited prior to bariatric surgery. Data collected included serum 25(OH)D concentrations, dietary and supplement intake of vitamin D, sun exposure measures, skin colour via spectrophotometry, and genotype analysis of several single nucleotide polymorphisms in the vitamin D metabolism pathway. Results showed a significant correlation between serum 25(OH)D concentrations and age, and serum 25(OH)D and ITAC score (natural skin colour). Natural skin colour accounted for 13.5% of variation in serum 25(OH)D, with every 10° increase in ITAC score (i.e., lighter skin) leading to a 9 nmol/L decrease in serum 25(OH)D. Multiple linear regression using age, ITAC score, and average UV index in the three months prior to testing, significantly predicted serum 25(OH)D concentrations ( R ² = 29.7%). Single nucleotide polymorphisms for all vitamin D genes tested, showed lower serum 25(OH)D for those with the rare genotype compared to the common genotype; this was most pronounced for fok1 and rs4588 , where those with the rare genotype were insufficient (vitamin D status in individuals with morbid obesity requires testing of 25(OH)D, but potential risk factors for this population include natural skin colour and age.

    Our recent review of the literature uncovered eleven obesity-specific quality of life questionnaires, all with incomplete demonstration of their measurement properties. Our objective was to validate a new self-administered questionnaire specific to morbid obesity to be used in clinical trials. The study was carried out at the bariatric surgery clinic of Laval Hospital, Quebec City, Canada. This study followed our description of health-related quality of life in morbid obesity from which we constructed the Laval Questionnaire. Its construct validity and responsiveness were tested by comparing the baseline and changes at 1-year follow-up in 6 domain scores (symptoms, activity/mobility, personal hygiene/clothing, emotions, social interactions, sexual life) with those of questionnaires measuring related constructs (SF-36, Impact of Weight on Quality of Life-Lite, Rosenberg Self-Esteem Scale and Beck Depression Inventory-II). 112 patients (67 who got bariatric surgery, 45 who remained on the waiting list during the study period) participated in this study. The analysis of the discriminative function of the questionnaire showed moderate-to-high correlations between the scores in each domain of our instrument and the corresponding questionnaires. The analysis of its evaluative function showed (1) significant differences in score changes between patients with bariatric surgery and those without, and (2) moderate-to-high correlations between the changes in scores in the new instrument and the changes in the corresponding questionnaires. Most of these correlations met the a priori predictions we had made regarding their direction and magnitude. The Laval Questionnaire is a valid measure of health-related quality of life in patients with morbid obesity and is responsive to treatment-induced changes.

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

  6. Increased plasma fibronectin concentrations in obesity

    Andersen, T; Dejgaard, A; Astrup, A

    In 23 morbidly obese patients we investigated the influence of a large weight loss (30.6 kg, range 17.5-90.8) on the plasma fibronectin concentrations. Further, changes in plasma fibronectin were related to serum insulin levels and to liver biochemistry.

    2017-01-01

    Conclusions: Weight-based enoxaparin dose led to the anticipated peak anti-Xa levels (0.2–0.6 IU/mL in most of the morbidly obese study patients undergoing surgery without any evidence of major side effects. The weight-based dosing of enoxaparin was also effective in preventing VTE in all patients. Although these results are promising, further comparative trials are needed in the setting of morbidly obese surgical patients.

    In spite of increased vigilance of undiagnosed type 2 diabetes (DM2), the prevalence of unknown DM2 in subjects with morbid obesity is not known. To assess the prevalence of undiagnosed DM2 and compare the performance of glycated A1c (HbA1c) and fasting glucose (FG) for the diagnosis of DM2 and prediabetes (preDM) in patients with morbid obesity. We measured fasting glucose and HbA1c in 537 consecutive patients with morbid obesity without previously known DM2. A total of 49 (9%) patients with morbid obesity had unknown DM2 out of which 16 (33%) fulfilled both the criteria for HbA1c and FG. Out of 284 (53%) subjects with preDM, 133 (47%) fulfilled both the criteria for HbA1c and FG. Measurements of agreement for FG and HbA1c were moderate for DM2 (κ = 0.461, p obesity.

    Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as "the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)" as a predictor for complications can lead to optimization of the patient care at bariatric centers. To determine the association between perioperative morbidity and the number of stapler firings during laparoscopic sleeve gastrectomy. This observational study was based on retrospective analysis of prospectively collected data in patients operated on for morbid obesity in a teaching hospital/tertiary referral center for general surgery. The patients who underwent LSG were analyzed in terms of the number of stapler firings used as a new potential risk predictor for postoperative complications after surgery, adjusting for other patient- and treatment-related factors. The study included 333 patients (209 women, 124 men, mean age: 40 ±11). During the first 30 days after surgery, complications were observed in 18 (5.41%) patients. Multivariate analysis showed that prolonging operative time increased morbidity (every minute, OR = 1.01; 95% CI: 1.00-1.02) and the complication rate increased with the number of stapler firings (every firing, OR = 1.91; 95% CI: 1.09-3.33; p = 0.023). Additional stapler firings above the usual number and a prolonged operation should alert a surgeon and the whole team about increased risk of postoperative complications.

  12. Systemic Inflammation and Lung Function Impairment in Morbidly Obese Subjects with the Metabolic Syndrome

    Astrid van Huisstede

    2013-01-01

    Full Text Available Background. Obesity and asthma are associated. There is a relationship between lung function impairment and the metabolic syndrome. Whether this relationship also exists in the morbidly obese patients is still unknown. Hypothesis. Low-grade systemic inflammation associated with the metabolic syndrome causes inflammation in the lungs and, hence, lung function impairment. Methods. This is cross-sectional study of morbidly obese patients undergoing preoperative screening for bariatric surgery. Metabolic syndrome was assessed according to the revised NCEP-ATP III criteria. Results. A total of 452 patients were included. Patients with the metabolic syndrome (n=293 had significantly higher blood monocyte (mean 5.3 versus 4.9, P=0.044 and eosinophil percentages (median 1.0 versus 0.8, P=0.002, while the total leukocyte count did not differ between the groups. The FEV1/FVC ratio was significantly lower in patients with the metabolic syndrome (76.7% versus 78.2%, P=0.032. Blood eosinophils were associated with FEV1/FVC ratio (adj. B −0.113, P=0.018. Conclusion. Although the difference in FEV1/FVC ratio between the groups is relatively small, in this cross-sectional study, and its clinical relevance may be limited, these data indicate that the presence of the metabolic syndrome may influence lung function impairment, through the induction of relative eosinophilia.

  14. ENU mutagenesis identifies mice with morbid obesity and severe hyperinsulinemia caused by a novel mutation in leptin.

    Chen-Jee Hong

    Full Text Available BACKGROUND: Obesity is a multifactorial disease that arises from complex interactions between genetic predisposition and environmental factors. Leptin is central to the regulation of energy metabolism and control of body weight in mammals. METHODOLOGY/PRINCIPAL FINDINGS: To better recapitulate the complexity of human obesity syndrome, we applied N-ethyl-N-nitrosourea (ENU mutagenesis in combination with a set of metabolic assays in screening mice for obesity. Mapping revealed linkage to the chromosome 6 within a region containing mouse Leptin gene. Sequencing on the candidate genes identified a novel T-to-A mutation in the third exon of Leptin gene, which translates to a V145E amino acid exchange in the leptin propeptide. Homozygous Leptin(145E/145E mutant mice exhibited morbid obesity, accompanied by adipose hypertrophy, energy imbalance, and liver steatosis. This was further associated with severe insulin resistance, hyperinsulinemia, dyslipidemia, and hyperleptinemia, characteristics of human obesity syndrome. Hypothalamic leptin actions in inhibition of orexigenic peptides NPY and AgRP and induction of SOCS1 and SOCS3 were attenuated in Leptin(145E/145E mice. Administration of exogenous wild-type leptin attenuated hyperphagia and body weight increase in Leptin(145E/145E mice. However, mutant V145E leptin coimmunoprecipitated with leptin receptor, suggesting that the V145E mutation does not affect the binding of leptin to its receptor. Molecular modeling predicted that the mutated residue would form hydrogen bond with the adjacent residues, potentially affecting the structure and formation of an active complex with leptin receptor within that region. CONCLUSIONS/SIGNIFICANCE: Thus, our evolutionary, structural, and in vivo metabolic information suggests the residue 145 as of special function significance. The mouse model harboring leptin V145E mutation will provide new information on the current understanding of leptin biology and novel mouse

  15. The lived experiences of being physically active when morbidly obese: A qualitative systematic review.

    Toft, Bente Skovsby; Uhrenfeldt, Lisbeth

    2015-01-01

    The aim is to identify facilitators and barriers for physical activity (PA) experienced by morbidly obese adults in the Western world. Inactivity and a sedentary lifestyle have become a major challenge for health and well-being, particularly among persons with morbid obesity. Lifestyle changes may lead to long-term changes in activity level, if facilitators and barriers are approached in a holistic way by professionals. To develop lifestyle interventions, the perspective and experiences of this group of patients are essential for success. The methodology of the systematic review followed the seven-step procedure of the Joanna Briggs Institute and was published in a protocol. Six databases were searched using keywords and index terms. Manual searches were performed in reference lists and in cited citations up until March 2015. The selected studies underwent quality appraisal in the Joanna Briggs-Qualitative Assessment and Review Instrument. Data from primary studies were extracted and were subjected to a hermeneutic text interpretation and a data-driven coding in a five-step procedure focusing on meaning and constant targeted comparison through which they were categorized and subjected into a meta-synthesis. Eight papers were included for the systematic review, representing the experiences of PA among 212 participants. One main theme developed from the meta-data analysis: "Identity" with the three subthemes: "considering weight," "being able to," and "belonging with others." The theme and subthemes were merged into a meta-synthesis: "Homecoming: a change in identity." The experiences of either suffering or well-being during PA affected the identity of adults with morbid obesity either by challenging or motivating them. A change in identity may be needed to feel a sense of "homecoming" when active.

  18. Renal Tubular Acidosis after Jejunoileal Bypass for Morbid Obesity: role of secondary hyperparathyroidism

    Andersen, NN; Ladefoged, NN

    1991-01-01

    The effect of calcium infusion was studied in patients with renal tubular acidosis (RTA) and secondary hyperparathyroidism. Both developed after jejunoileal bypass operation (JIB) for morbid obesity. In three of four cases the acidification defect was abolished, probably due to a decrease of serum...... parathyroid hormone. As we found RTA in 9% (95% confidence limits 2-21%) of our patients, screening for acidosis is recommended in obesity patients after malabsorptive operations. RTA can be verified through an ammonium loading test. Before deciding on re-establishing bowel continuity due to RTA, we suggest...... and vitamin D supplementation. If RTA can be abolished through correction of calcium homeostasis, reoperation may be avoided. Before deciding on re-establishing bowel continuity in JIB patients with RTA, we therefore suggest that patients be evaluated for secondary hyperparathyroidism and any calcium...

  19. Dietary Protein in the Prevention of Diet-Induced Obesity and Co-Morbidities

    Tastesen, Hanne Sørup

    mice were fed obesity‐promoting diets with protein from different sources, in different forms and at different levels to evaluate the affect on development of obesity, glucose intolerance and dyslipidemia. Results: In the present study the dietary level of protein, 16 versus 32 percent energy from...... protein, was found to be negligible in development of obesity and co‐morbidities in mice. Seafood protein with high endogenous taurine and glycine contents was found to prevent diet‐induced adiposity and dyslipidemia, both in ad libitum and pair‐fed settings. The ability of seafood proteins to prevent...... that the source and form of protein has great impact on development and prevention of diet‐induced adiposity, dyslipidemia, hyperinsulinemia and impairment of glucose tolerance through modulations of voluntary locomotor activity, energy expenditure and energy substrate metabolism in mice...

    2012-12-01

    Achalasia is a relatively rare condition with a prevalence estimated at less than 0.001 %. Laparoscopic or robotic Heller myotomy is an effective surgical treatment for achalasia. We present the first published case of a morbidly obese achalasia patient treated with robotic Heller myotomy and Dor fundoplication. The operative time was 175 min, with an estimated blood loss of 110 ml. The patient had a normal bowel transit on postoperative day 2, and he was discharged on postoperative day 4 on a liquid diet. A follow-up at 2 months showed significant resolved symptoms of achalasia.

  1. Gastric emptying studies in the morbidly obese before and after gastroplasty

    1986-11-01

    Dual isotope gastric emptying studies were performed on 16 morbidly obese patients before and after gastroplasty to determine the effect of this surgery on the rate of emptying. The solid and liquid phases of gastric emptying were compared with a normal control group. In the 900-g and 50-g meals there was a significant difference in the mean half emptying time between solid and liquid phases of emptying (p less than 0.05). Pre-operatively, the 900-g meal half emptying times of both solids and liquids and the 50-g liquid phase meal did not differ significantly between obese patients and the control group. However, in the solid phase of the 50-g meal obese patients differed significantly from a control group (p = 0.007). Three months after gastroplasty, gastric emptying of 50-g meals from the total stomach was not significantly changed from the pre-operative 50-g meal values in ten of 12 patients (p less than 0.05) and no change in total stomach emptying times were seen at 12 mo compared to the 3-mo study (p less than 0.05). Emptying of the pouch alone for both solids and liquids was significantly faster than the pre-operative and postoperative total stomach studies. Gastric emptying in the obese is normal with large meals, but is delayed in small meals. In most patients, gastroplasty does not result in slower emptying of meals.

    2012-12-01

    Although the benefits of preoperative weight loss and adequacy of dietary patterns in bariatric surgery is well-recognized, the nutritional strategies in the preoperative period have been scarcely investigated. We aimed to evaluate the impact of intensive and standard nutritional interventions on body weight, energy intake, and eating quality. This is a retrospective study in which 32 patients undergoing intensive nutritional intervention, with low-calorie diet (10 kcal/kg) and biweekly visits, were pair-matched by age, sex, and body mass index with 32 patients under a standard nutritional intervention, based on a general dietary counseling. Twenty-four-hour food recall was used to assess energy intake and to derive healthy eating index (HEI). The follow-up preoperative period varied from 8 to 16 weeks. Weight loss was observed in 72% of the patients from the intensive intervention group and 75% of the patients from the standard intervention group. According to the mixed model analysis, time effect on weight loss in both groups was significant (P = 0.0002); however, no difference was found between the intervention groups (P = 0.71). The time effect was significant in both groups for energy intake reduction as well (P eating quality was expressed by the nutrient score of the HEI that increased significantly overtime (P = 0.02), also without distinction between the groups (P = 0.61). Both intensive and standard nutritional interventions promoted weight loss, energy intake reduction, and improvement of eating quality in morbidly obese patients during preoperative period.

    INTRODUCTION: 30-40% of the adult population in Denmark are overweight and 10-13% are obese. The number of bariatric operations reached 3,000 in 2009, and it is expected that a third or more of the patients need corrective plastic surgery. MATERIAL AND METHODS: Medical charts of all patients who...... had abdominoplasty performed during a 2.5-year period. We included 72 patients of whom 21 had lost weight after bariatric surgery and 51 patients had lost weight through diet and exercise or had not been overweight. RESULTS: The overall complication rate was 21% (43% of the post-bariatric patients...... a significantly higher maximum weight, weight at the time of abdominoplasty and had lost more BMI units. CONCLUSION: Our data show that post-bariatric patients who have an abdominoplasty performed suffer a high complication rate which appears to be higher than that of patients who do not have bariatric surgery...

  5. Morbid obesity as a risk factor for hospitalization and death due to 2009 pandemic influenza A(H1N1 disease.

    Oliver W Morgan

    Full Text Available BACKGROUND: Severe illness due to 2009 pandemic A(H1N1 infection has been reported among persons who are obese or morbidly obese. We assessed whether obesity is a risk factor for hospitalization and death due to 2009 pandemic influenza A(H1N1, independent of chronic medical conditions considered by the Advisory Committee on Immunization Practices (ACIP to increase the risk of influenza-related complications. METHODOLOGY/PRINCIPAL FINDINGS: We used a case-cohort design to compare cases of hospitalizations and deaths from 2009 pandemic A(H1N1 influenza occurring between April-July, 2009, with a cohort of the U.S. population estimated from the 2003-2006 National Health and Nutrition Examination Survey (NHANES; pregnant women and children or=20 year olds, hospitalization was associated with being morbidly obese (BMI>or=40 for individuals with ACIP-recognized chronic conditions (OR = 4.9, 95% CI 2.4-9.9 and without ACIP-recognized chronic conditions (OR = 4.7, 95%CI 1.3-17.2. Among 2-19 year olds, hospitalization was associated with being underweight (BMIor=20 years without ACIP-recognized chronic medical conditions death was associated with obesity (OR = 3.1, 95%CI: 1.5-6.6 and morbid obesity (OR = 7.6, 95%CI 2.1-27.9. CONCLUSIONS/SIGNIFICANCE: Our findings support observations that morbid obesity may be associated with hospitalization and possibly death due to 2009 pandemic H1N1 infection. These complications could be prevented by early antiviral therapy and vaccination.

    Obesity and knee osteoarthritis are among the most frequent chronic conditions affecting Americans aged 50 to 84 years. To estimate quality-adjusted life-years lost due to obesity and knee osteoarthritis and health benefits of reducing obesity prevalence to levels observed a decade ago. The U.S. Census and obesity data from national data sources were combined with estimated prevalence of symptomatic knee osteoarthritis to assign persons aged 50 to 84 years to 4 subpopulations: nonobese without knee osteoarthritis (reference group), nonobese with knee osteoarthritis, obese without knee osteoarthritis, and obese with knee osteoarthritis. The Osteoarthritis Policy Model, a computer simulation model of knee osteoarthritis and obesity, was used to estimate quality-adjusted life-year losses due to knee osteoarthritis and obesity in comparison with the reference group. United States. U.S. population aged 50 to 84 years. Quality-adjusted life-years lost owing to knee osteoarthritis and obesity. Estimated total losses of per-person quality-adjusted life-years ranged from 1.857 in nonobese persons with knee osteoarthritis to 3.501 for persons affected by both conditions, resulting in a total of 86.0 million quality-adjusted life-years lost due to obesity, knee osteoarthritis, or both. Quality-adjusted life-years lost due to knee osteoarthritis and/or obesity represent 10% to 25% of the remaining quality-adjusted survival of persons aged 50 to 84 years. Hispanic and black women had disproportionately high losses. Model findings suggested that reversing obesity prevalence to levels seen 10 years ago would avert 178,071 cases of coronary heart disease, 889,872 cases of diabetes, and 111,206 total knee replacements. Such a reduction in obesity would increase the quantity of life by 6,318,030 years and improve life expectancy by 7,812,120 quality-adjusted years in U.S. adults aged 50 to 84 years. Comorbidity incidences were derived from prevalence estimates on the basis of life

  7. Parathyroid hormone, but not vitamin D, is associated with the metabolic syndrome in morbidly obese women and men: a cross-sectional study

    Hager Helle

    2009-02-01

    Full Text Available Abstract Background The prevalence of vitamin D insufficiency and secondary hyperparathyroidism is high among morbidly obese subjects. Further, low serum levels of 25-hydroxyvitamin D (25 [OH]D and magnesium have been associated with increased risk of the metabolic syndrome (MS, and recently, a possible link between PTH and MS has been reported. Although it is well known that the synthesis and secretion of PTH is regulated by serum levels of calcium, phosphate, magnesium and 25(OHD, less is known about the possible clustered affiliation of these parameters with MS. We aimed to explore whether MS is associated with abnormal serum levels of PTH, 25(OHD and magnesium in a population of morbidly obese patients. Methods Fasting serum levels of 25(OHD, PTH and magnesium were assessed in a cross-sectional cohort study of 1,017 consecutive morbidly obese patients (68% women. Multiple logistic regression analyses were used to assess the independent effect of PTH, 25(OHD and magnesium on the odds for MS (National Cholesterol Education Program [NCEP] after adjustment for confounding factors. Results Sixty-eight percent of the patients had MS. Patients with MS had lower mean serum magnesium (P Conclusion The PTH level, but not the vitamin D level, is an independent predictor of MS in treatment seeking morbidly obese Caucasian women and men. Randomized controlled clinical trials, including different therapeutic strategies to lower PTH, e.g. calcium/vitamin D supplementation and weight reduction, are necessary to explore any cause-and-effect relationship.

  8. Does morbid obesity negatively affect the hospital course of patients undergoing treatment of closed, lower-extremity diaphyseal long-bone fractures?

    2011-01-03

    Obesity is prevalent in the developed world and is associated with significant costs to the health care system. The effect of morbid obesity in patients operatively treated for long-bone fractures of the lower extremity is largely unknown. The National Trauma Data Bank was accessed to determine if morbidly obese patients (body mass index >40) with lower extremity fractures have longer length of hospital stay, higher cost, greater rehabilitation admission rates, and more complications than nonobese patients. We identified patients with operatively treated diaphyseal femur (6920) and tibia (5190) fractures. Polytrauma patients and patients younger than 16 years were excluded. Morbidly obese patients were identified by ICD-9 and database comorbidity designation (femur, 131 morbidly obese; tibia, 75 morbidly obese). Patients meeting these criteria who were not morbidly obese were used as controls. Sensitivity analyses were performed to analyze patients with isolated trauma to the tibia or femur. Morbidly obese patients were more likely to be admitted to a subacute facility. Length of stay trended higher in morbidly obese patients. There was no significant relationship between obesity and inpatient mortality or inpatient complications. These trends held true when considering patients with multiple injuries and patients who had isolated long-bone injuries. Our study showed that morbidly obese patients may have greater rehabilitation needs following long-bone fractures in the lower extremity. Our study showed no difference in mortality or complications, although further studies are needed to confirm these findings. Copyright 2011, SLACK Incorporated.

  9. PNPLA3 Expression Is Related to Liver Steatosis in Morbidly Obese Women with Non-Alcoholic Fatty Liver Disease

    Gemma Aragonès

    2016-04-01

    Full Text Available Recent reports suggest a role for the Patatin-like phospholipase domain-containing protein 3 (PNPLA3 in the pathology of non-alcoholic fatty liver disease (NAFLD. Lipid deposition in the liver seems to be a critical process in the pathogenesis of NAFLD. The aim of the present work was to evaluate the association between the liver PNPLA3 expression, key genes of lipid metabolism, and the presence of NAFLD in morbidly obese women. We used real-time polymerase chain reaction (PCR analysis to analyze the hepatic expression of PNPLA3 and lipid metabolism-related genes in 55 morbidly obese subjects with normal liver histology (NL, n = 18, simple steatosis (SS, n = 20, and non-alcoholic steatohepatitis (NASH, n = 17. Liver biopsies were collected during bariatric surgery. We observed that liver PNPLA3 expression was increased in NAFLD than in NL. It was also upregulated in SS than in NL. Interestingly, we found that the expression of PNPLA3 was significantly higher in severe than mild SS group. In addition, the expression of the transcription factors LXRα, PPARα, and SREBP2 was positively correlated with PNPLA3 liver expression. Regarding rs738409 polymorphism, GG genotype was positive correlated with the presence of NASH. In conclusion, our results show that PNPLA3 could be related to lipid accumulation in liver, mainly in the development and progression of simple steatosis.

    Recent reports suggest a role for the Patatin-like phospholipase domain-containing protein 3 (PNPLA3) in the pathology of non-alcoholic fatty liver disease (NAFLD). Lipid deposition in the liver seems to be a critical process in the pathogenesis of NAFLD. The aim of the present work was to evaluate the association between the liver PNPLA3 expression, key genes of lipid metabolism, and the presence of NAFLD in morbidly obese women. We used real-time polymerase chain reaction (PCR) analysis to analyze the hepatic expression of PNPLA3 and lipid metabolism-related genes in 55 morbidly obese subjects with normal liver histology (NL, n = 18), simple steatosis (SS, n = 20), and non-alcoholic steatohepatitis (NASH, n = 17). Liver biopsies were collected during bariatric surgery. We observed that liver PNPLA3 expression was increased in NAFLD than in NL. It was also upregulated in SS than in NL. Interestingly, we found that the expression of PNPLA3 was significantly higher in severe than mild SS group. In addition, the expression of the transcription factors LXRα, PPARα, and SREBP2 was positively correlated with PNPLA3 liver expression. Regarding rs738409 polymorphism, GG genotype was positive correlated with the presence of NASH. In conclusion, our results show that PNPLA3 could be related to lipid accumulation in liver, mainly in the development and progression of simple steatosis.

  11. Are we prepared for a growing population? Morbid obesity and its implications in Irish emergency departments.

    2012-01-31

    Two percent of the Irish population is morbidly obese with this figure expected to rise significantly. This survey aimed to establish the present logistical capacity of Irish emergency departments (EDs) to adequately cater for the bariatric patients. A telephone survey was carried out of 37 health service executive EDs over a 5-day period in October 2008. Questions were posed to the departmental lead nurse regarding facilities (Supplemental digital content 1). No ED had adequate facilities. Two of 37 units questioned had on-site hoists designed to lift patients of more than 170 kg. Four departments had rapid access to mattresses within the hospital and three of these four had access to beds and trolleys for weighing patients. Two percent of the Irish population is morbidly obese with this figure expected to rise significantly to more than 150 kg. One department had access to commodes, chairs, wheelchairs and trolleys from inpatient services. All departments had extra-wide blood pressure cuffs and 12 had a difficult airways trolley. Necessary infrastructure and equipment for bariatric patients is deficient in the majority of Irish EDs.

    Laparoscopic sleeve gastrectomy (LSG) has demonstrated high long-term effectiveness and major advantages over other techniques. The objective of this study was to analyze changes in physical fitness parameters in morbidly obese patients during 6 months after LSG. We conducted a descriptive observational study with 6-month follow-up in 72 LSG patients, evaluating changes in body mass index (BMI), functional capacity (6-min walking test), hand grip strength (manual dynamometry), flexibility (fingertip-to-floor test), balance (Flamingo test), physical activity level (International Physical Activity Questionnaire, IPAQ), and perception of general physical fitness (International Fitness Scale [IFIS] questionnaire). The ANOVA revealed significant improvements in BMI, functional capacity, flexibility, balance, and physical activity level (P fitness in most cases. No significant changes were found in dominant hand (P = 0.676) or non-dominant hand (P = 0.222) dynamometry. General physical fitness was positively correlated with BMI and distance in the 6-min test, and was negatively correlated with fingertip-to-floor distance. Morbidly obese patients showed major improvements at 6 months after LSG in functional capacity, balance, mobility, and physical activity, with no change in grip strength. These improvements were related to a better self-perception of general physical fitness.

    The aim of this study was to investigate hepatic chemerin mRNA, serum chemerin concentration, and immunohistochemical staining for chemerin and and chemokine receptor-like 1 (CMKLR1) in hepatic tissue in 56 morbidly obese women with nonalcoholic fatty liver disease (NAFLD) and to search for a relationship with metabolic and histopathological features. Chemerin mRNA was assessed by quantitative real-time PCR, chemerin, and CMKLR1 immunohistochemical expression with specific antibodies, while serum chemerin concentration was assessed with commercially available enzyme-linked immunosorbent assays. Serum chemerin concentration reached 874.1 ±234.6 ng/ml. There was no difference in serum chemerin levels between patients with BMI steatosis, and definite nonalcoholic steatohepatitis (NASH). Liver chemerin mRNA was observed in all included patients and was markedly, but insignificantly, higher in those with BMI ≥ 40 kg/m2, hepatocyte ballooning, greater extent of steatosis, and definite NASH. Hepatic chemerin mRNA might be a predictor of hepatic steatosis, hepatocyte ballooning, and NAFLD activity score (NAS) but seemed not to be a primary driver regulating liver necroinflammatory activity and fibrosis. The lack of association between serum chemerin and hepatic chemerin mRNA may suggest that adipose tissue but not the liver is the main source of chemerin in morbidly obese women.

    Objective The aim of this study was to evaluate whether a change in the routine feeding strategy applied after pancreatoduodenectomy (PD) from nasojejunal tube (NJT) feeding to early oral feeding improved clinical outcomes. Methods An observational cohort study was performed in 102 consecutive patients undergoing PD. In period 1 (n = 51, historical controls), the routine postoperative feeding strategy was NJT feeding. This was changed to a protocol of early oral feeding with on-demand NJT feeding in period 2 (n = 51, consecutive prospective cohort). The primary outcome was time to resumption of adequate oral intake. Results The baseline characteristics of study subjects in both periods were comparable. In period 1, 98% (n = 50) of patients received NJT feeding, whereas in period 2, 53% (n = 27) of patients did so [for delayed gastric empting (DGE) (n = 20) or preoperative malnutrition (n = 7)]. The time to resumption of adequate oral intake significantly decreased from 12 days in period 1 to 9 days in period 2 (P = 0.015), and the length of hospital stay shortened from 18 days in period 1 to 13 days in period 2 (P = 0.015). Overall, there were no differences in the incidences of complications of Clavien–Dindo Grade III or higher, DGE, pancreatic fistula, postoperative haemorrhage and mortality between the two periods. Conclusions The introduction of an early oral feeding strategy after PD reduced the time to resumption of adequate oral intake and length of hospital stay without negatively impacting postoperative morbidity.

    The prevalence of obesity is increasing. The mortality and morbidity among obese intensive care unit (ICU) patients has been a matter of concern. Most of the retrospective studies performed have yielded contradictory results. Recently, two large prospective studies showed that respiratory failure......, length of mechanical ventilation and ICU acquired infections were increased in obese patients. Obesity was, however, not associated with increased mortality. The results were confirmed by a meta-analysis which showed that obesity was associated with increased morbidity but not with increased mortality...

  17. Association of Sun Exposure, Skin Colour and Body Mass Index with Vitamin D Status in Individuals Who Are Morbidly Obese

    Clare F. Dix

    2017-10-01

    Full Text Available Vitamin D deficiency is a common issue, particularly in obese populations, and is tested by assessing serum 25(OHD concentrations. This study aimed to identify factors that contribute to the vitamin D status in fifty morbidly obese individuals recruited prior to bariatric surgery. Data collected included serum 25(OHD concentrations, dietary and supplement intake of vitamin D, sun exposure measures, skin colour via spectrophotometry, and genotype analysis of several single nucleotide polymorphisms in the vitamin D metabolism pathway. Results showed a significant correlation between serum 25(OHD concentrations and age, and serum 25(OHD and ITAC score (natural skin colour. Natural skin colour accounted for 13.5% of variation in serum 25(OHD, with every 10° increase in ITAC score (i.e., lighter skin leading to a 9 nmol/L decrease in serum 25(OHD. Multiple linear regression using age, ITAC score, and average UV index in the three months prior to testing, significantly predicted serum 25(OHD concentrations (R2 = 29.7%. Single nucleotide polymorphisms for all vitamin D genes tested, showed lower serum 25(OHD for those with the rare genotype compared to the common genotype; this was most pronounced for fok1 and rs4588, where those with the rare genotype were insufficient (<50 nmol/L, and those with the common genotype were sufficient (≥50 nmol/L. Assessing vitamin D status in individuals with morbid obesity requires testing of 25(OHD, but potential risk factors for this population include natural skin colour and age.

    Living with chronic illnesses can be stressful and may negatively impact persons' self-esteem. Personal factors, like self-efficacy and illness perceptions, and also factors related to the environment, activity, and participation may be associated with self-esteem in chronic illness populations. This cross-sectional comparative study explored sociodemographic variables, work, physical activity, illness perceptions, and general self-efficacy in relation to self-esteem in persons with morbid obesity and in persons with chronic obstructive pulmonary disease (COPD). The study had a cross-sectional design. A total of 223 eligible participants were recruited from patient education courses, and data were collected at baseline. Self-esteem was measured with The Rosenberg self-esteem scale; the general self-efficacy scale was used to measure self-efficacy, and brief illness perception questionnaire was also used. This is an instrument assessing cognitions about the illness and emotional responses towards it. Multivariate linear regression was used in the statistical analyses. In obese participants (n = 134), higher self-esteem was associated with lower emotional response, a shorter timeline, and higher general self-efficacy. In COPD participants (n = 89), higher self-esteem was associated with higher general self-efficacy. The independent variables accounted for 42.9% (morbid obesity) and 49.4% (COPD) of the self-esteem variance. In participants in both illness groups, higher self-efficacy was associated with increased self-esteem. A shorter timeline and lower emotional response to illness was related to higher self-esteem only for the obese participants. The results indicate that believing in one's capacity to cope with everyday challenges is important for self-esteem in persons with morbid obesity and in persons with COPD, whereas illness perceptions related to the duration of illness and the coping with emotions also is important for self-esteem in persons with morbid

    Roux-en-Y gastric bypass surgery (RYGBP) is one of the most common bariatric surgeries, which is being performed using various techniques like gastrojejunostomy by hand swen, linear or circular stapler. Abdominal pain is a common complaint following laparoscopic gastric bypass procedure (LGBP), which has different aetiologies, such as overeating, adhesion, internal herniation, bile reflux and many more. In this study LGBP was performed in an ante-colic ante-gastric pattern in a double loop manner and the prevalence and distribution of pain in morbidly obese patients undergoing LGBP was assessed. The aim of this study was to analyze the distribution and frequency of post LGBP pain in morbidly obese patients. This study was performed on 190 morbidly obese patients referred to Hazrat Rasoul Hospital in Tehran. After LGBP, pain was measured in the following intervals: 24 hours, one week and one month after the operation. Before the operation onset, 2 mg Keflin and 5000 IU subcutaneous heparin were administered as prophylaxis. LGBP was performed using five ports including: one 11 mm port was placed 15-20 cm far from the xiphoid, one 12-mm port in mid-clavicular line at the level of camera port, one 5-mm port in subcostal area in ante-axillary region in the left, another 5-mm port in the right mid-clavicular area and a 5-mm port in sub-xyphoid. All operations were done by the same team. Staple was used for all anastomoses and hand sewn technique to close the staple insertion site. The mesenteric defect was left open and no effort was made to repair it. The results of this study showed that 99.94 % of the patients had complains of pain in the first 24 hours of post operation, about 60% after one week and 29.5 % still had pain after one month. In addition, left upper quadrant (LUQ) was found to be the most prevalent site for the pain in 53.7% of the patients in the first 24 hours, 59.6% after one week and 16.8% after one month (except for obscure pain) with a significance

  20. Preoperative weight loss in super-obese patients: study of the rate of weight loss and its effects on surgical morbidity

    Marco Aurelio Santo

    2014-01-01

    Full Text Available OBJECTIVES: The incidence of obesity and particularly super obesity, has increased tremendously. At our institution, super obesity represents 30.1% of all severely obese individuals in the bariatric surgery program. In super obesity, surgical morbidity is higher and the results are worse compared with morbid obesity, independent of the surgical technique. The primary strategy for minimizing complications in these patients is to decrease the body mass index before surgery. Preoperative weight reduction can be achieved by a hypocaloric diet, drug therapy, an intragastric balloon, or hospitalization. The objective of this study was to analyze the results of a period of hospitalization for preoperative weight loss in a group of super-obese patients. METHODS: Twenty super-obese patients were submitted to a weight loss program between 2006 and 2010. The mean patient age was 46 years (range 21-59. The mean BMI was 66 kg/m2 (range 51-98 and 12 were women. The average hospital stay was 19.9 weeks and the average weight loss was 19% of the initial weight (7-37%. The average caloric intake was 5 kcal/kg/day. After the weight loss program, the patients underwent gastric bypass surgery. RESULTS: The statistical analysis revealed that after 14 weeks of treatment (15% loss of initial weight, the weight loss was not significant. All patients had satisfactory surgical recovery and were discharged after an average of 4.6 days. CONCLUSION: In super obesity, preoperative weight loss is an important method for reducing surgical risks. Hospitalization and a hypocaloric diet are safe and effective. After 14 weeks, the weight loss rate stabilized, signaling the time of surgical intervention in our study.

    To report on the unique, innovative management of a super morbidly obese patient presenting for fertility preservation in the setting of Grade 2 endometrioid endometrial adenocarcinoma. A back-to-back oocyte retrieval and robot-assisted total laparoscopic hysterectomy (RA-TLH) with bilateral salpingo-oophorectomy (BSO) was performed in a 37-year-old nulligravid woman with super morbid obesity (BMI 63 kg/m 2 ) with endometrial cancer. the successful retrieval of oocytes for fertility preservation and oncologic intervention via RA-TLH with BSO in the same operative and anesthetic episode. This combined procedure strategy was successful in our case and is a feasible option for similar high-risk patients in the future. Identifying safe and effective approaches for oocyte retrieval in morbidly obese patients represents a pressing need as obesity rates rise among reproductive-aged women. Back-to-back oocyte retrieval and RA-TLH with BSO are not only feasible, but could also decrease significant anesthetic risks for morbidly obese patients.

    We have experienced numerous cases of super morbid obesity (SMO), defined by a BMI of ≥50 kg/m 2 , in which laparoscopic sleeve gastrectomy (LSG) was not able to achieve a sufficient weight loss effect. However, the most appropriate procedure for the treatment of SMO has not yet been established. The subjects included 248 successive patients who underwent surgery at our hospital from June 2006 to December 2012. We divided the subjects into an SMO group (BMI, 50 to <70 kg/m 2 ) and a morbid obesity (MO) group (BMI, 35 to <50 kg/m 2 ). The subjects underwent LSG, LSG with duodenojejunal bypass (LSG/DJB), or laparoscopic Roux-en-Y gastric bypass (LRYGB). The weight loss effects, safety of surgery, and metabolic profile changes were compared. Sixty-two subjects were classified into the SMO group (25%). The percent excess weight loss (%EWL) after LSG among the patients in the SMO group was not significantly different from that of patients who underwent other procedures. LSG was associated with a significantly lower success rate in terms of weight loss (%EWL ≥ 50%), in comparison to the weight loss at 1 year after LRYGB and at 2 years after LSG/DJB and LRYGB. Among the patients in the MO group, the %EWL and the rate of successful weight loss did not differ to a statistically significant extent. This study demonstrated that in patients with SMO, LSG/DJB and LRYGB can achieve superior weight loss effects in comparison to LSG.

    Full Text Available Abstract Background Overweight and obesity are growing health problems both worldwide and in Malaysia due to such lifestyle changes as decreased physical activity (PA, increased sedentary behavior and unhealthy eating habits. This study examined the levels and patterns of PA among normal-weight and overweight/obese adults and to investigate the association between PA level and overweight/obesity in Malaysian adults. Methods This study used data from the 2015 National Health and Morbidity Survey (NHMS, a nationwide cross-sectional survey that implemented a two-stage stratified random sampling design. Respondents aged 18 years and above (n = 17,261 were included in the analysis. The short version of International Physical Activity Questionnaire (IPAQ was administered to assess the respondents’ PA levels. The respondents’ height and weight were objectively measured and body mass index (BMI was calculated. The respondents were categorized according to BMI as either normal-weight (18.5–24.9 kg/m2 or overweight/obese (≥ 25 kg/m2. Descriptive and complex sample logistic regression analyses were employed as appropriate. Results Overall, approximately 1 in 2 respondents (51.2% were overweight/obese, even though the majority (69.0% reporting at least a moderate level of PA (total PA ≥ 10 MET-hours/week. In both normal-weight and overweight/obese groups, a significantly higher prevalence of high PA (total PA ≥ 50 MET-hours/week was observed among men than women (p < 0.001, but women reported a significantly higher prevalence of low and moderate PA than men (p < 0.001. Men reported significantly higher activity levels (in MET-hours/week than women with regard to walking, vigorous-intensity PA and total PA (p < 0.001. Overweight/obese men reported a significantly lower level of vigorous-intensity PA and total PA than normal-weight men (p < 0.001. A low level of PA was associated with the risk of overweight/obesity

    2017-01-01

    Subjects with morbid obesity commonly use Non-Nutritive Sweeteners (NNS), but the health-related effects of NNS have been questioned. The objectives of this study were to explore the associations between theuse of NNS and the health and lifestyle in subjects with morbid obesity. This cross-sectional study included subjects with morbid obesity (BMI ≥ 40 kg/m 2 or ≥35 kg/m 2 with obesity-related comorbidity). Information about demographics, physical and mental health, and dietary habits was collected, and a blood screen was taken. One unit of NNS was defined as 100 ml beverages with NNS or 2 tablets/units of NNS for coffee or tea. The associations between the intake of NNS and the health-related variables were analyzed with ordinal regression analyses adjusted for age, gender and BMI. One hundred subjects (women/men 83/17; mean age 44.3 years (SD 8.5)) were included. Median intake of NNS was 3.3 units (range 0 - 43). Intake of NNS was not associated with BMI ( p  = 0.64). The intake of NNS was associated with reduced heavy physical activity ( p  = 0.011), fatigue ( p  unhealthy lifestyle, reduced physical and mental health and unfavourable dietary habits with increased energy intake including sugar, and reduced intake of some vitamins.

    associated with the change of solid foods consumed (by weight, p = 0.01; by energy content, p = 0.02). The change of pouch volume was negatively associated with the change of energy from beverages (p = 0.005). In conclusion, it seems impossible to tailor the reduction of food intake through adjustments...... of the surgical dimensions, at least within the ranges of our observations. Increased food consumption and decreased energy intake with beverages may be caused by late dilations, or vice versa.......This study investigated possible determinants of food intake change after gastroplastry. Preoperatively and 6 and 12 months postoperatively, 27 morbidly obese patients were prospectively examined with 7-day food registration and radiologic measurement of pouch volume and stoma diameter.

    Full Text Available Living donor liver donation (LDLD is an alternative to cadaveric liver donation. We aimed at identifying risk factors and developing a score for prediction of postoperative complications (POCs after LDLD in donors. This is a retrospective cohort study in 688 donors between June 1995 and February 2014 at Hospital Sírio-Libanês and A.C. Camargo Cancer Center, in São Paulo, Brazil. Primary outcome was POC graded ≥III according to the Clavien-Dindo classification. Left lateral segment (LLS, left lobe (LL, and right lobe resections (RL were conducted in 492 (71.4%, 109 (15.8%, and 87 (12.6% donors, respectively. In total, 43 (6.2% developed POCs, which were more common after RL than LLS and LL (14/87 (16.1% versus 23/492 (4.5% and 6/109 (5.5%, resp., p<0.001. Multivariate analysis showed that RL resection (OR: 2.81, 95% CI: 1.32 to 3.01; p=0.008, smoking status (OR: 3.2, 95% CI: 1.35 to 7.56; p=0.012, and blood transfusion (OR: 3.15, 95% CI: 1.45 to 6.84; p=0.004 were independently associated with POCs. RL resection, intraoperative blood transfusion, and smoking were associated with increased risk for POCs in donors.

    An experience with laparoscopic sleeve gastrectomy using the natural orifice specimen extraction (NOSE) technique. Bariatric surgery is nowadays the only long term effective obesity treatment method. Twenty one consecutive patients underwent laparoscopic sleeve gastrectomy with the use of natural orifice specimen extraction (NOSE) in the Surgical Clinic of Faculty Hospital Ostrava between May 2012 and August 2012. Inclusion criteria were the body mass index (BMI) higher than 35 kg/m2 or higher than 32 kg/m2 accompanied with relevant comorbidities. Among 21 patients in this series, there were three men (14.3%) and 18 women (85.7%). Their mean age was 40.9±10.2 years. Their mean preoperative BMI was 40.4±4.6 kg/m2. No patient had previous bariatric surgery, one patient had laparoscopic fundoplication. All operations were completed laparoscopically with no conversions to an open procedure. In two cases, laparoscopic cholecystectomy was performed and the gallbladder was extracted along with the gastric specimen by transgastric approach. Laparoscopic sleeve gastrectomy is a safe and effective bariatric procedure with low morbidity and mortality. Based on our initial experiences it could be an indication for NOSE with transgastric approach. Obese patients would benefit from this approach due to the elimination of wound complications (Tab. 2, Fig. 3, Ref. 22).

    2017-01-01

    Previous research has shown cognitive dysfunction to be present in a significant number of individuals with obesity. The objective of this study was to assess the neuropsychological profile of morbidly obese patients referred to weight-loss treatment. An extensive battery of neuropsychological tests with well-known normative data covering various cognitive domains was administered to 96 patients. The test results were transformed to z-scores for comparisons with normative data. As a means of determining level of cognitive impairment within the group, deficit scores were applied. Group comparisons on the different cognitive domains were conducted between patients with depressive symptoms and patients reporting no such symptoms. As illustrated in mean z-scores, the patients demonstrated lower performance compared to normative data on visual memory (mean -.26, CI -.43 to -.09, p  = .003), speed of information processing (mean -.22, CI -.34 to -.09, p  = .001), executive functions (mean -.28, CI -.40 to -.16, p  ability, motor function, and working memory. The deficit scores, however, revealed working memory and motor function to be significantly impaired within the group as well. Patients with depressive symptoms differed from patients without such symptoms on visual memory (mean .43, CI .07 to .80, p  = .021). Some characteristic cognitive weaknesses and strengths were evident at the group level, although pronounced variation was observed. Deficits in executive functions, information processing, and attention should be taken into consideration in clinical practice.

    2010-01-01

    Metabolic syndrome is a result of multiple risk factors of atherosclerosis and diabetes. Obesity is an especially well recognized etiological factor. A rapidly increasing number of obese people constitutes a major social health problem in the developed, as well as developing countries. Bariatric surgeries are among methods of obesity treatment that gain on popularity. They include adjustable silicone gastric banding (ASGB), and adjustable laparoscopic gastric banding (ALGB). The aim of our study was to analyze and present the most typical radiological images obtained during 130 upper gastrointestinal tract examinations in patients after ASGB or ALGB in the last three years. ASGB and ALGB are effective and safe. However, they are connected with some postoperative complications. Application of these surgical procedures requires periodic, long-term radiological evaluations and cooperation between surgeons and radiologists. The radiologist must be familiar with bariatric surgical techniques, their complications and typical radiological presentations

    Full Text Available Background and Objectives: The present study was conducted with objective to study the incidence of obesity and associated co-morbidities in patients admitted to CMS-TH, Bharatpur.Materials and Methods: One hundred and fifty consecutive overweight patients from the January 2009 to December 2012 with Basal metabolic index (BMI>25 and obese patients (BMI>30 were included in this hospital based prospective study. Detailed evaluation of risk factors and family history of other diseases were taken, other obesity related indicators like WPRO, 2000 for BMI, waist circumference (NCEP ATP III and NCEP for South Asian ethnicity NCEP– National Cholesterol Education Program and waist hip ratio (WHO criteria were measured and comparison done in order to detect best method for application. These cases were evaluated for associated co-morbid condition and metabolic syndrome which were diagnosed using NCEP ATP III criteria.Results: The mean age of patients was 52.7 years. Commonest co-existing risk factors were alcohol consumption, smoking, hypertension and type 2 diabetes mellitus. Evaluation based on WHO criteria revealed that 56.7% patients were overweight, 38.7 % were obese class II and 4.6 % were class II. While 45.1% male and 69.1% female patients had central obesity. The figure was 81.7 % for males and 94.1% for females with WHO criteria using waist hip ratio. Risk factors like alcohol consumption (52.7%, smoking (52.7% and fatty liver disease (22.66% were the commonest co-morbid conditions.Conclusion: In the present study, risk factors of alcohol, smoking and hypertension and co-morbid conditions diabetes mellitus, dyslipidemia, ischemic heart disease, stroke and fatty liver were noted. Waist hip ratio was the best indicator to detect central obesity and co-morbid conditions and recommended to be used for Nepali population.JCMS Nepal. 2015;11(3:16-19

  11. Bariatric surgery in morbidly obese insulin resistant humans normalises insulin signalling but not insulin-stimulated glucose disposal.

    Mimi Z Chen

    Full Text Available Weight-loss after bariatric surgery improves insulin sensitivity, but the underlying molecular mechanism is not clear. To ascertain the effect of bariatric surgery on insulin signalling, we examined glucose disposal and Akt activation in morbidly obese volunteers before and after Roux-en-Y gastric bypass surgery (RYGB, and compared this to lean volunteers.The hyperinsulinaemic euglycaemic clamp, at five infusion rates, was used to determine glucose disposal rates (GDR in eight morbidly obese (body mass index, BMI=47.3 ± 2.2 kg/m(2 patients, before and after RYGB, and in eight lean volunteers (BMI=20.7 ± 0.7 kg/m2. Biopsies of brachioradialis muscle, taken at fasting and insulin concentrations that induced half-maximal (GDR50 and maximal (GDR100 GDR in each subject, were used to examine the phosphorylation of Akt-Thr308, Akt-473, and pras40, in vivo biomarkers for Akt activity.Pre-operatively, insulin-stimulated GDR was lower in the obese compared to the lean individuals (P<0.001. Weight-loss of 29.9 ± 4 kg after surgery significantly improved GDR50 (P=0.004 but not GDR100 (P=0.3. These subjects still remained significantly more insulin resistant than the lean individuals (p<0.001. Weight loss increased insulin-stimulated skeletal muscle Akt-Thr308 and Akt-Ser473 phosphorylation, P=0.02 and P=0.03 respectively (MANCOVA, and Akt activity towards the substrate PRAS40 (P=0.003, MANCOVA, and in contrast to GDR, were fully normalised after the surgery (obese vs lean, P=0.6, P=0.35, P=0.46, respectively.Our data show that although Akt activity substantially improved after surgery, it did not lead to a full restoration of insulin-stimulated glucose disposal. This suggests that a major defect downstream of, or parallel to, Akt signalling remains after significant weight-loss.

    Visceral adiposity is associated with decreased serum adiponectin levels, peripheral resistance to insulin and an increased risk of cardio-metabolic complications. However, the link between adiponectin expression in visceral adipose tissue (VAT), its serum levels and metabolic protection is controversial. The aim of this study was to investigate the relationship between the adiponectin gene expression in VAT and clinical and metabolic parameters in patients with severe obesity. This is a cross-sectional study that included 51 severely obese patients (age 43.24±11.29 years, BMI 45.13±8.67 kg/m2), extensively evaluated clinically and biologically (metabolic tests, serum adiponectin measurements, HOMA-IR) before bariatric surgery. Omental adipose tissue was sampled during the intervention and the relative quantification of adiponectin gene expression was performed by real-time PCR, using beta-actin as reference gene. Adiponectin mRNA in VAT was significantly higher in obese insulin-sensitive patients than in the rest of obese patients (p<0.05) and negatively correlated with HOMA-IR (r =-0.354, p=0.016) and uric acid (r =-0.304, p=0.045). After adjustment for gender, TG/HDL ratio and uric acid, adiponectin expresion (β= -0.439, p=0.001), waist circumference (β=0.467, p=0.001) and serum adiponectin (β =-0.339, p=0.011) remained significantly associated with HOMA-IR, together explaining more than 50% of its variation. In severely obese patients, adiponectin gene expression in VAT is negatively correlated with serum levels of uric acid and is an independent determinant, together with anthropometric parameters of visceral obesity and serum adiponectin levels, of insulin resistance.

    C-Reactive protein (CRP) has been associated with the macro- and microvascular effects of hypertension and diabetes mellitus. Referring to serum cortisol, it has been proposed to contribute to the pathogenesis of metabolic syndrome, and it has been demonstrated that weight loss normalizes cortisol levels and improves insulin resistance. The aims of this study were to analyze CRP and cortisol levels pre- and postoperatively in morbidly obese patients undergoing a laparoscopic sleeve gastrectomy and to correlate them with weight loss and parameters associated with cardiovascular risk. A prospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between October 2007 and May 2011 was performed. A total of 40 patients were included in the study. CRP levels decreased significantly 12 months after surgery (median reduction of 8.9 mg/l; p = 0.001). Serum cortisol levels decreased significantly 6 months after surgery (median reduction of 34.9 μg/dl; p = 0.001). CRP values reached the normal range (cortisol, a significant association was observed with the cardiovascular risk predictor (triglyceride/high-density lipoprotein cholesterol ratio) from the 6th month after surgery onward (Pearson correlation coefficient, 0.559; p = 0.008). CRP levels are increased preoperatively and in the postoperative course up to 1 year after surgery. Serum cortisol levels remain elevated until the 6th month after surgery. From this moment onward, serum cortisol is associated with the cardiovascular risk predictor reflecting the cardiovascular risk decreasement during the weight loss.

  14. Ursodeoxycholic acid exerts farnesoid X receptor-antagonistic effects on bile acid and lipid metabolism in morbid obesity.

    Bile acids (BAs) are major regulators of hepatic BA and lipid metabolism but their mechanisms of action in non-alcoholic fatty liver disease (NAFLD) are still poorly understood. Here we aimed to explore the molecular and biochemical mechanisms of ursodeoxycholic acid (UDCA) in modulating the cross-talk between liver and visceral white adipose tissue (vWAT) regarding BA and cholesterol metabolism and fatty acid/lipid partitioning in morbidly obese NAFLD patients. In this randomized controlled pharmacodynamic study, we analyzed serum, liver and vWAT samples from 40 well-matched morbidly obese patients receiving UDCA (20 mg/kg/day) or no treatment three weeks prior to bariatric surgery. Short term UDCA administration stimulated BA synthesis by reducing circulating fibroblast growth factor 19 and farnesoid X receptor (FXR) activation, resulting in cholesterol 7α-hydroxylase induction mirrored by elevated C4 and 7α-hydroxycholesterol. Enhanced BA formation depleted hepatic and LDL-cholesterol with subsequent activation of the key enzyme of cholesterol synthesis 3-hydroxy-3-methylglutaryl-CoA reductase. Blunted FXR anti-lipogenic effects induced lipogenic stearoyl-CoA desaturase (SCD) in the liver, thereby increasing hepatic triglyceride content. In addition, induced SCD activity in vWAT shifted vWAT lipid metabolism towards generation of less toxic and more lipogenic monounsaturated fatty acids such as oleic acid. These data demonstrate that by exerting FXR-antagonistic effects, UDCA treatment in NAFLD patients strongly impacts on cholesterol and BA synthesis and induces neutral lipid accumulation in both liver and vWAT.

    The current study aimed to determine the relationship between self-reported sleep duration and morbid obesity in an employee population. Baptist Health South Florida conducts an annual Health Risk Assessment (HRA) for its employees. Data for this cross-sectional study was collected via this HRA in 2014, and included information on self-reported sleep duration, height and weight for body mass index (BMI), and other biometric measures. Average sleep duration was categorized as short sleep (employees who were sleeping for less than 6 hr compared to 13% and 14% among those sleeping for 6-7.9 hours, and 8 or more hours respectively. In regression analyses, persons who slept less than 6 hr had almost twice the odds of morbid obesity compared to those who slept 6-7.9 hr (odds ratio = 1.8; 1.5-2.2). Our finding that short sleep duration (employees, especially those who work in shift duties to reduce the risk of morbid obesity and other comorbid conditions. Future studies are needed to further explore the relationship of sleep duration and morbid obesity in employee populations.

    2018-01-01

    Full Text Available Compartment syndrome occurs when pressure within a closed muscle or bone compartment builds to dangerous levels. This pressure can decrease blood flow to nerve and muscle cells, leading to ischemia and organ dysfunction. Challenges in providing enteral nutrition for abdominal compartment syndrome (ACS patients include the increase risk for developing gastrointestinal symptoms such as diarrhea, constipation and distention. There are limited reports available on the nutritional management of ACS patients in the ICU especially those with morbid obesity condition to guide dietitians in providing nutritional support for these patients.  Here, we report the enteral nutrition management of a mechanically ventilated, morbidly obese patient with ACS in a critical care setting by adopting postpyloric feeding, using prokinetic agents and implementing PO2/FiO2 ratio calculation for prescription of most suitable enteral formula.

  20. Assessment of Oral Conditions and Quality of Life in Morbid Obese and Normal Weight Individuals: A Cross-Sectional Study.

    Joselene Martinelli Yamashita

    Full Text Available The aim of this study was to identify the impact of oral disease on the quality of life of morbid obese and normal weight individuals. Cohort was composed of 100 morbid-obese and 50 normal-weight subjects. Dental caries, community periodontal index, gingival bleeding on probing (BOP, calculus, probing pocket depth, clinical attachment level, dental wear, stimulated salivary flow, and salivary pH were used to evaluate oral diseases. Socioeconomic and the oral impacts on daily performances (OIDP questionnaires showed the quality of life in both groups. Unpaired Student, Fisher's Exact, Chi-Square, Mann-Whitney, and Multiple Regression tests were used (p<0.05. Obese showed lower socio-economic level than control group, but no differences were found considering OIDP. No significant differences were observed between groups considering the number of absent teeth, bruxism, difficult mastication, calculus, initial caries lesion, and caries. However, saliva flow was low, and the salivary pH was changed in the obese group. Enamel wear was lower and dentine wear was higher in obese. More BOP, insertion loss, and periodontal pocket, especially the deeper ones, were found in obese subjects. The regression model showed gender, smoking, salivary pH, socio-economic level, periodontal pocket, and periodontal insertion loss significantly associated to obesity. However, both OIDP and BOP did not show significant contribution to the model. The quality of life of morbid obese was more negatively influenced by oral disease and socio-economic factors than in normal weight subjects.

  1. Effect of Weight Reduction Following Bariatric Surgery on Serum Visfatin and Adiponectin Levels in Morbidly Obese Subjects

    Mohammad Javad Hosseinzadeh-Attar

    2013-04-01

    Full Text Available Objective: Adipokines are signaling and mediator proteins secreted from adipose tissue. A novel adipokine, visfatin, was reported as a protein which was mainly expressed in visceral adipose tissue. Controversial results have been shown regarding the changes of adipokines following weight reduction. So we investigated the effects of weight reduction on serum concentrations of adiponectin and visfatin in morbidly obese subjects. Methods: 35 severely obese patients (26 females and 9 males, aged 15-58 years, were studied. Anthropometric parameters and biochemical parameters as well as adiponectin and visfatin were analyzed before and 6 weeks after weight reduction. Results: Anthropometric indices decreased significantly. Blood levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride were reduced significantly. The reduction of visfatin and the elevation of adiponectin were significant as well. However, other parameters like fasting glucose and insulin did not change. Moreover, we could not find any significant correlation between the change of serum visfatin and that of adiponectin. Conclusions: 6-week weight reduction after bariatric surgery resulted in decreased serum visfatin and increased adiponectin levels. However, we cannot find any significant correlation between changes of adiponectin, visfatin, BMI, waist circumference, and insulin resistance. Further studies with different design are suggested to clarify these associations.

    2012-12-01

    Full Text Available Bariatric surgery has to be considered in the management of severely obese adolescents when all conservative measures have been proven to be unresponsive. Short term metabolic and neurohormonal profile changes after robotic-assisted gastroplication are evaluated. The benefits and the usefulness of this surgical-reversal procedure in adolescent need to be defined. Fiveteen years old girl with body mass index 42.2 kg/m2, hyperinsulinism, hyperandrogenism, amenorrhea, polycystic ovarian syndrome, hypertension with left ventricular hypertrophy. Gastric volume after surgical procedure reduction was 80-100 mL. One month postoperatively significant weigh loss was obtained. Insulin levels, insulin-resistance, leptin and ghrelin concentration were substantially ameliorated. We can conclude that bariatric surgery should be considered for a minority of severely obese adolescents under the supervision of a multidisciplinary pediatric team. Our experience confirmed that the gastroplication is safe, feasible and effective and furthermore is a reversible technique. The early improvement of the obesity co-morbities is allowed. The increased surgical accuracy in robotic assistance could limit postoperative complications rate in obese adolescents.

  4. Influence of psychological variables in morbidly obese patients undergoing bariatric surgery after 24 months of evolution.

    Rodríguez-Hurtado, José; Ferrer-Márquez, Manuel; Fontalba-Navas, Andrés; García-Torrecillas, Juan Manuel; Olvera-Porcel, M Carmen

    Bariatric surgery is considered a more effective means of achieving weight loss than non-surgical options in morbid obesity. Rates of failure or relapse range from 20 to 30%. The study aims to analyse the influence of psychological variables (self-esteem, social support, coping strategies and personality) in the maintenance of weight loss after bariatric surgery. A cohort study was conducted involving 64 patients undergoing bariatric surgery for 24 months. At the end of the follow-up period, patients were divided into 2sub-cohorts classified as successes or failures. Success or favorable development was considered when the value of percent excess weight loss was 50 or higher. No statistically significant differences were observed between the 2groups in any variable studied. All patients had high self-esteem (87,3 those who failed and 88,1 those who are successful) and social support (90,2 and 90,9). Patients who succeed presented higher scores for cognitive restructuring (57,1) and were more introverted (47,1), while those who failed scored more highly in desiderative thinking (65,7) and were more prone to aggression (50,7) and neuroticism (51,7). High self-esteem and social support does not guarantee successful treatment. The groups differed in how they coped with obesity but the data obtained do not justify the weight evolution. In the absence of psychopathology, personality trait variability between patients is insufficient to predict the results. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U.

    2006-04-13

    Among polygenic mouse models of obesity, the New Zealand obese (NZO) mouse exhibits the most severe phenotype, with fat depots exceeding 40% of total body weight at the age of 6 mo. Here we dissected the components of energy balance including feeding behavior, locomotor activity, energy expenditure, and thermogenesis compared with the related lean New Zealand black (NZB) and obese B6.V-Lep(ob)/J (ob/ob) strains (11% and 65% fat at 23 wk, respectively). NZO mice exhibited a significant hyperphagia that, when food intake was expressed per metabolic body mass, was less pronounced than that of the ob/ob strain. Compared with NZB, NZO mice exhibited increased meal frequency, meal duration, and meal size. Body temperature as determined by telemetry with implanted sensors was reduced in NZO mice, but again to a lesser extent than in the ob/ob strain. In striking contrast to ob/ob mice, NZO mice were able to maintain a constant body temperature during a 20-h cold exposure, thus exhibiting a functioning cold-induced thermogenesis. No significant differences in spontaneous home cage activity were observed among NZO, NZB, and ob/ob strains. When mice had access to voluntary running wheels, however, running activity was significantly lower in NZO than NZB mice and even lower in ob/ob mice. These data indicate that obesity in NZO mice, just as in humans, is due to a combination of hyperphagia, reduced energy expenditure, and insufficient physical activity. Because NZO mice differ strikingly from the ob/ob strain in their resistance to cold stress, we suggest that the molecular defects causing hyperphagia in NZO mice are located distal from leptin and its receptor.

  6. [A new method of gastric shunting for treatment of patients with morbid obesity].

    Grubnik, V V; Golliak, V P; Kresiun, M S

    2013-01-01

    The gastric shunting (GSH) method, permitting to control the patients body mass more effectively and promoting complete remission of diabetes mellitus type II, was elaborated. In 2008 - 2009 yrs 29 patients (9 men, 20 women) were operated on for morbid obesity, using shunting interventions. In 21 patients (the first group) a standard GSH was performed, in 8 (second group)--a modified operation. In 18-24 mo the excessive patient's body mass in patients of the first group have reduced by 62.8%, of the second group--by 89.3%. Complete compensation of diabetes mellitus type II with rejection from insulin and other antidiabetic preparations was achieved in 4 patients of the first group and in all--in the second group. Resistence for insulin have had lowered in patients of both groups, including in the first group--in 1,4 times, in the second group--in 3.2 times. Thus, preliminary results accurately demonstrate, that application of a modified GSH method is more effective, concerning the patients body mass reduction and achievement of complete compensation of diabetes mellitus type II.

  7. Psychological Profile and Quality of Life of Morbid Obese Patients Attending a Cognitive Behavioural Program

    Rebecca Marzocchi

    2008-12-01

    Full Text Available The results show that 27% of cases had a BES score ≥ 17, indicative of possible binge eating, and 13% had a BES ≥ 27, largely indicative of binge eating, with a higher prevalence in females. The BDI score was above normal in 30% of males and 45% of females, and 13% of females were in the range of moderate-severe depression. BES and BDI were significantly correlated with each other. Orwell-97 was much higher in females, and similarly the generic PGWB was indicative of a poorer HRQL in females. PGWB was positively associated with age, without any effect of BMI. The association with age was maintained in female, not in males. Both the Orwell-97 and the PGWB were associated with both BES and BDI in both genders. Psychological distress is common and largely variable in patients attending CBT for morbid obesity. This data should be considered for individual treatment protocols, and should be compared with similar series of patients enrolled for bariatric surgery.

  8. Lipogenic potential of liver from morbidly obese patients with and without non-insulin-dependent diabetes

    1991-01-01

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

  9. Evolution of subclinical hypothyroidism and its relation with glucose and triglycerides levels in morbidly obese patients after undergoing sleeve gastrectomy as bariatric procedure.

    2014-05-01

    There is an increased prevalence of subclinical hypothyroidism (SCH) in patients with obesity. It is unclear if this biochemical abnormality may be a secondary phenomenon of obesity or a real hypothyroid state. A retrospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between October 2007 and November 2012 was performed. Weight loss, body mass index (BMI) and excess weight loss, baseline glucose, lipid profiles, and TSH levels were obtained before operation and postoperative determinations at 3, 6, and 12 months after surgery. Sixty patients were included. Prevalence of subclinical hypothyroidism was 16.7% preoperatively, 10% at 3 months, 3.3% at 6 months, and 1.7% at 12 months. A significant correlation could be established between TSH decrease and weight loss at 12 months (Pearson 0.603; p = 0.007). TSH decrease showed a significant correlation with glucose and glycated hemoglobin decrease from 6th month onwards. Referring to lipid profile, an association of TSH decrease with total cholesterol, LDL cholesterol, or HDL cholesterol could not be determined. A significant association between TSH decrease and triglycerides and cardiovascular risk index triglycerides/HDL cholesterol reductions could also be established 12 months after surgery. SCH is usually corrected after bariatric surgery, while there are no significant changes in total or LDL cholesterol. This suggests that, in morbidly obese subjects, SCH is, in most patients, just a consequence of the abnormal fat accumulation and not a real hypothyroid state.

  10. Reduced Systemic Levels of IL-10 Are Associated with the Severity of Obstructive Sleep Apnea and Insulin Resistance in Morbidly Obese Humans

    Sonia Leon-Cabrera

    2015-01-01

    Full Text Available Obstructive sleep apnea (OSA has been related to elevation of inflammatory cytokines and development of insulin resistance in morbidly obese (MO subjects. However, it is still unclear whether the systemic concentration of anti-inflammatory mediators is also affected in MO subjects directly related to the severity of OSA and level of insulin resistance. Normal weight and MO subjects were subjected to overnight polysomnography in order to establish the severity of OSA, according to the apnea-hypopnea index (AHI. Blood samples were obtained for estimation of total cholesterol and triglycerides, insulin, glucose, insulin resistance, tumor necrosis factor alpha (TNF-α, interleukin 12 (IL12, and interleukin 10 (IL-10. Serum levels of IL-10 were significantly lower in MO subjects with OSA than in MO and control individuals without OSA. Besides being inversely associated with serum TNF-α and IL-12, decreased IL-10 levels were significantly related to increased AHI, hyperinsulinemia, and insulin resistance. Serum IL-10 is significantly reduced in morbidly obese subjects with severe OSA while also showing a clear relationship with a state of hyperinsulinemia and insulin resistance probably regardless of obesity in the present sample. It may be of potential clinical interest to identify the stimulatory mechanisms of IL-10 in obese individuals with OSA.

  11. Epicardial fat thickness correlates with P-wave duration, left atrial size and decreased left ventricular systolic function in morbid obesity.

    Fernandes-Cardoso, A; Santos-Furtado, M; Grindler, J; Ferreira, L A; Andrade, J L; Santo, M A

    2017-08-01

    Epicardial fat (EF) is increased in obesity and has important interactions with atrial and ventricular myocardium. Most of the evidence in this scenario can be confused by the presence of comorbidities such as hypertension, diabetes and dyslipidemia, which are very common in this population. The influence of EF on atrial remodeling and cardiac function demands further investigation on morbidly obese without these comorbidities. We prospectively recruited 20 metabolically healthy morbidly obese and 20 normo-weights controls. The maximum P-wave duration (PWD) was analyzed by 12-lead electrocardiogram. Left atrial diameter (LAD), left ventricular ejection fraction (LVEF) and EF thickness (EFT) were evaluated by two-dimensional echocardiography.

    Operating room surgical table failure is a rare event but can lead to a dangerous situation when it does occur. The dangers can be compounded in the presence of obesity, especially in the anesthetized or sedated patient. We present a case of a near-miss fall of a morbidly obese patient while turning the patient in preparation to transfer from the operating room table to the hospital bed when 2 fractured bolts in the tilt cylinder mechanism led to an operating room table failure.

    Full Text Available Background Nonalcoholic fatty liver disease (NAFLD is one of the most common causes of chronic liver disease including simple steatosis to nonalcoholic steatohepatitis (NASH. NASH could progress to cirrhosis and liver cancer. The prevalence of NAFLD is increasing by increasing the prevalence of obesity. Objectives This study was designed to determine the prevalence of NASH in morbidly obese patients undergoing sleeve bariatric surgery and its correlation with other comorbidities. Patients and Methods In this analytical cross-sectional study, 114 morbidly obese patients undergoing sleeve gastrectomy were selected. Liver ultrasonography was performed for all patients before surgery and NAFLD existence and its grade was determined by hyperechoic texture and fatty infiltration. The liver enzymes and lipid profile were also measured. Prevalence of NAFLD in these patients and its correlation with other comorbid conditions (e.g. diabetes mellitus, hyperlipidemia, hypertension, hypothyroidism and ischemic heart disease were evaluated by SPSS software version 18. Results One hundred fourteen patients with a mean age of 33.96 ± 9.92 years and mean BMI of 43.61 ± 5.77 kg/m2 were enrolled (48 males and 66 females. The prevalence of NAFLD was 16.7%. NAFLD existence was associated with systolic blood pressure, hyperlipidemia, hemoglobin, hematocrit, triglyceride, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and potassium (P < 0.05. Conclusions According to high prevalence of NAFLD in morbidly obese patients undergoing sleeve gastrectomy in Iran, we suggest using gold standard diagnostic method to determine the exact NAFLD prevalence and evaluation of impact of sleeve surgery on NAFLD in short and long term follow-up periods.

    The presence of hypercholesterolemia is currently not considered a selection criteria for performing gastric restrictive or diversionary bariatric surgery. We prospectively investigated the effects of the bilio-intestinal bypass (BI-bypass) with a wide cholecysto-jejunal anastomosis and of adjustable gastric banding (AGB) on blood lipid concentrations in obese patients. To clarify the mechanism of the hypocholesterolemic effect of the BI-bypass, daily fecal sterol excretion was measured by gas-liquid chromatography (GLC). At 1 year after BI-bypass compared to baseline, the hypercholesterolemic (n=18) and the normocholesterolemic (n=19) patients significantly reduced total (-38% and -27%, respectively), LDL (-47% and -24%, respectively) and HDL (-11% and -13%, respectively) cholesterol and total / HDL cholesterol ratio (-25% and -13%, respectively). At 1 year after AGB, the total / HDL cholesterol ratio was significantly decreased (-11%) compared to baseline in hypercholesterolemic (n=12) but not in normocholesterolemic (n=6) patients, while total and LDL cholesterol were not affected in both groups. At 3 years after BI-bypass compared to baseline, the hypercholesterolemic (n=9) and the normocholesterolemic (n=11) patients significantly reduced total (-43% and -28%, respectively) and LDL (-53% and -29%, respectively) cholesterol and total / HDL cholesterol ratio (-38% and -21%, respectively). The BI-bypass induced a significant (P <0.005; n=7) 6-fold increase in mean fecal cholesterol output. The BI-bypass but not the AGB leads to a persistent and marked beneficial effect on blood LDL cholesterol associated with an increased cholesterol fecal output. BI-bypass but not AGB is indicated in morbidly obese patients with hypercholesterolemia.

    Turner syndrome (TS), resulting from complete/partial X chromosomal monosomy, is associated with multiple co-morbidities and increased mortality. Although multidisciplinary management is recommended, TS women's health care is sub-optimal. This study evaluates a multidisciplinary adult TS service. Retrospective cohort study of 82 patients attending the quarterly TS clinic from December 2003 to December 2014. Evaluation included (1) demographics, (2) TS standardized co-morbidity screening, and (3) estrogen therapy use. Data analysis involved frequency statistics, T tests and polychoric correlation analysis. Median age at TS diagnosis was 14 years (range 0-65 years), with 12% of women aged >18 years. Median age at initial consultation was 31 years (range 16-65 years). Only 14% of patients were transition program referrals. XO karyotype occurred in 30%. Primary amenorrhea predominated; however, 37% of TS women were not taking estrogen therapy. The proportion of patients not previously screened (44-76%) and those with positive screening diagnoses (5-53%) varied according to co-morbidity. The mean (± standard deviation) number of co-morbidities identified increased following TS clinic screening (7.0 ± 2.6 post-screening vs. 4.4 ± 2.3 pre-screening; p < 0.0001). Polychoric correlation analysis identified particular co-morbidity groupings (including metabolism-related) and increased co-morbidities with primary amenorrhea. A multidisciplinary adult TS clinic improves health surveillance with increased identification of co-morbidities and initiation of estrogen therapy.

    epidemic in the United States. Obese patients present several physiopathologic changes and important comorbidities, which the anesthesiologist must be aware of. Gastric reduction surgery is increasingly more frequent, and the perioperative period has unique characteristics, with cardiovascular and pulmonary changes that make it a real challenge for the professional involved. The hospital should also be prepared to receive those patients, with adequate equipment, a multidisciplinary team, and postoperative care. The objective of this study was to demonstrate that the patient with morbid obesity is not only a person with weight excess and, therefore, we attempted to describe the main conducts to be followed. CONTENTS: Here we present the main physiopathologic changes in the patient with morbid obesity, as well as the epidemiological data and correlated diseases. We review the doses of the drugs used in anesthesia, and the best pre, intra, and postoperative approach. CONCLUSIONS: The care of the patient with morbid obesity demands careful planning, which begins with patient selection, continues with a detailed preoperative and individualized intraoperative periods, and extends through the postoperative period, when the incidence of pulmonary, cardiovascular, and infectious complications is greater than in the non-obese population. The involvement of a multidisciplinary team, including Internal Medicine, Anesthesiology, General Surgery, Nursing, Psychology, Physical Therapy, Nutrition, and Intensive Care, is extremely important for good results.

    Micronutrient deficiencies occur in morbidly obese patients. The aim of this study was to assess vitamin deficiencies prior to bariatric surgery including vitamin K about which there is little data in this population. A prospective assessment of 118 consecutive patients was performed. Clinical allied with haematological and biochemical variables were measured. Micronutrients measured included vitamins K1 , PIVKA-II (protein-induced in vitamin K absence factor II), vitamin D, vitamin B12 (holotranscobalamin), iron, transferrin and folate. Patients were aged 49 ± 11 [mean (SD, standard deviation)] years, body mass index (BMI) 50 ± 8 kg/m(2), 66% female and 78% Caucasian. Hypertension was present in 47% and type 2 diabetes in 32%. Vitamin D supplements had been prescribed in 8%. Micronutrient insufficiencies were found for vitamin K (40%), vitamin D (92%) and vitamin B12 (25%), and also iron (44%) and folate (18%). Normocalcaemic vitamin D insufficiency with secondary hyperparathyroidism was present in 18%. Iron and transferrin levels were associated with age, sex and estimated glomerular filtration rate. Vitamin K levels were associated with age, and inversely with BMI and diabetes mellitus; and PIVKA-II with smoking, triglycerides and liver function markers. Vitamin D levels were associated with statin use and prescription of supplements and inversely with BMI. Vitamin B12 levels were associated with ethnicity and HbA1c. Micronutrient status shows differing relationships with age, gender and BMI. Vitamin K insufficiency was present in 40% and not related to deficiencies in other vitamins or micronutrients. Vitamin D and vitamin K supplementation should be considered prebariatric surgery in patients with diabetes or severe insulin resistance. © 2014 John Wiley & Sons Ltd.

    Obesity is a serious chronic disease that increases the risk of numerous co-morbidities including metabolic syndrome, cardiovascular disease and cancer as well as increases risk of mortality, leading some to suggest this condition represents accelerated aging. Obesity is associated with significant increases in oxidative stress in vivo and, despite the well-explored relationship between oxidative stress and aging, the role this plays in the increased mortality of obese subjects remains an unanswered question. Here, we addressed this by undertaking a comprehensive, longitudinal study of a group of high fat-fed obese mice and assessed both their changes in oxidative stress and in their performance in physiological assays known to decline with aging. In female C57BL/6J mice fed a high-fat diet starting in adulthood, mortality was significantly increased as was oxidative damage in vivo. High fat-feeding significantly accelerated the decline in performance in several assays, including activity, gait, and rotarod. However, we also found that obesity had little effect on other markers of function and actually improved performance in grip strength, a marker of muscular function. Together, this first comprehensive assessment of longitudinal, functional changes in high fat-fed mice suggests that obesity may induce segmental acceleration of some of the aging process.

    The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG.

    This study was designed to evaluate the efficacy and safety of computed tomography (CT)-guided drainage in treating infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity. From January 2007 to June 2009, 21 patients (9 men and 12 women; mean age, 39.2 (range, 26–52) years) with infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity underwent image-guided percutaneous drainage. All procedures were performed using CT guidance and 8- to 12-Fr pigtail drainage catheters. Immediate technical success was achieved in all 21 infected collections. In 18 of 21 collections, we obtained progressive shrinkage of the collection with consequent clinical success (success rate 86%). In three cases, the abdominal fluid collection was not resolved, and the patients were reoperated. Among the 18 patients who avoided surgery, 2 needed replacement of the catheter due to obstruction. No major complications occurred during the procedure. The results of our study support that CT-guided percutaneous drainage is an effective and safe method to treat infected abdominal fluid collections due to gastric leak in patients who had previously underwent laparoscopic sleeve gastrectomy for morbid obesity. It may be considered both as a preparatory step for surgery and a valuable alternative to open surgery. Failure of the procedure does not, however, preclude a subsequent surgical operation.

    Full Text Available Background: Obesity is sweeping across continents and is a major public health concern of the modern society. Aims: The main objective of this study was to study the demographic, anthropometric and dietary patterns of the morbidly obese and study region wise variation in their nutrient intake. Materials and Methods: The study was conducted on 101 morbidly obese individuals from different regions of India who attended the Bariatric clinic of a tertiary care hospital in India. Their socio-demographic details, anthropometric measurements were collected. The dietary assessment was done using a 24 hour dietary recall and a food frequency questionnaire. The study was approved by the Institutional review board and informed consent was obtained from them. Results: More than 3/4th of the patients were females and 61 per cent had Type 2 diabetes mellitus. The mean age of the male and female population was 41.3 + 15.5 years and 36.7 + 11.9 years respectively. Their mean BMI was 41kg/m2. The mean daily intake of calories was more than 2200kcal/day with a gross deficit in the intake of micronutrients. Bonferroni Test showed that there was region wise variation in dietary intake, South Indian female population had the lowest intake of the micronutrients and those from East India had the highest intake. In the male population, there was a significant regional difference in intake of Proteins (p=0.039 and Energy (p=0.024. Independent Sample T test showed that South Indian had the highest intake of Energy and proteins. Anthropometric measures showed positive relation with various macronutrient intakes. Conclusion: The obese patients require intense counselling by a dedicated team of an endocrinologist, psychiatrist, dietician, bariatric surgeon and a social worker to make achievable changes in the quality of life of the morbidly obese patients. Regional influences must be considered when counselling the patient.

    The presence of insulin resistance (IR) is determinant for endothelial dysfunction associated with obesity. Although recent studies have implicated the involvement of mitochondrial superoxide and inflammation in the defective nitric oxide (NO)-mediated responses and subsequent endothelial dysfunction in IR, other mechanisms could compromise this pathway. In the present study, we assessed the role of asymmetric dimethylarginine (ADMA) and arginase with respect to IR-induced impairment of endothelium-dependent vasodilatation in human morbid obesity and in a non-obese rat model of IR. We show that both increased ADMA and up-regulated arginase are determinant factors in the alteration of the l-arginine/NO pathway associated with IR in both models and also that acute treatment of arteries with arginase inhibitor or with l-arginine significantly alleviate endothelial dysfunction. These results help to expand our knowledge regarding the mechanisms of endothelial dysfunction that are related to obesity and IR and establish potential therapeutic targets for intervention. Insulin resistance (IR) is determinant for endothelial dysfunction in human obesity. Although we have previously reported the involvement of mitochondrial superoxide and inflammation, other mechanisms could compromise NO-mediated responses in IR. We evaluated the role of the endogenous NOS inhibitor asymmetric dimethylarginine (ADMA) and arginase with respect to IR-induced impairment of l-arginine/NO-mediated vasodilatation in human morbid obesity and in a non-obese rat model of IR. Bradykinin-induced vasodilatation was evaluated in microarteries derived from insulin-resistant morbidly obese (IR-MO) and non-insulin-resistant MO (NIR-MO) subjects. Defective endothelial vasodilatation in IR-MO was improved by l-arginine supplementation. Increased levels of ADMA were detected in serum and adipose tissue from IR-MO. Serum ADMA positively correlated with IR score and negatively with pD2 for bradykinin. Gene

    Full Text Available Purpose: Despite the associated health consequences, obesity is infrequently documented as a problem in medical charts. The purpose of this study is to determine whether a simple intervention (routine listing of the BMI on the medical chart will increase physician documentation of obesity in the medical record. Methods: Participants were resident physicians in a family medicine residency program. Participants were randomly assigned to either an experimental group or a control group. For experimental group physicians, the Body Mass Index was listed alongside other vital signs of patients seen in an ambulatory setting. Physician documentation of patient obesity was assessed by chart review after patient visits. Documentation was defined as inclusion of obesity on the problem list or in the progress note. Results: The intervention did not significantly increase the rate of documentation of obesity in the medical chart. Several reasons for the lack of change are explored, including the difficulty of treating obesity successfully.

    Hepatic 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) activity, which converts cortisone (inactive) to cortisol, is downregulated in obesity. However, this compensation fails in obese with metabolic abnormalities, such as diabetes. To further characterize the tissue-specific cortisol regeneration in obesity, we have investigated the mRNA expression of genes related to local cortisol production, i.e., 11β-HSD1, hexose-6-phosphate dehydrogenase (H6PDH) and cortisol action, glucocorticoid receptor (GR) and a cortisol target gene, phosphoenolpyruvate carboxykinase (PEPCK) in the liver, and visceral (VAT) and subcutaneous (SAT) adipose tissues from morbidly obese patients with and without metabolic syndrome (MS). Fifty morbidly obese patients undergoing bariatric surgery, 14 men (mean age, 41.3 ± 3.5 years; BMI, 48.0 ± 3.6 kg/m(2)) and 36 women (mean age, 44.6 ± 1.9 years; BMI, 44.9 ± 1.2 kg/m(2)), were classified as having MS (MS+, n = 20) or not (MS-, n = 30). Tissue mRNA levels were measured by real-time polymerase chain reaction. Hepatic mRNA levels of these genes were higher in obese patients with MS (11β-HSD1, P = 0.002; H6PDH, P = 0.043; GR, P = 0.033; PEPCK, P = 0.032) and positively correlated with the number of clinical characteristics that define the MS. The expression of the four genes positively correlated among them. In contrast to the liver, these genes were not differently expressed in VAT or SAT, when MS+ and MS- obese patients were compared. Coordinated liver-specific upregulation of genes involved in local cortisol regeneration and action support the concept that local hepatic hypercortisolism contributes to development of MS in morbidly obese patients.

    Obesity is the most common nutritional disorder affecting Western societies. An estimated 3.7 million Canadians are considered to be overweight, a condition associated with hypertension, accelerated atherosclerosis, diabetes and a host of other medical problems. We have identified a 3 generation kindred in which morbid obesity appears to segregate in an autosomal dominant manner. All individuals were examined. Mass (kg) and heights (m) were measured in order to determine a body mass index (BMI) for each individual. Those individuals with BMI of greater than or equal to 30.0 were designated as affected. In the pedigree studied 25 individuals met this criteria and 12 of these were morbidly obese (BMI greater or equal to 40.0). A search of candidate genes proved unfruitful. A linkage study was initiated. All individuals in the pedigree were genotyped for microsatellite markers which were spaced every 20 centimorgans (cM). Positive evidence of linkage was detected with markers which map to 1q31-32 (lod score of 3.6 at {theta} = 0.05). Notably, strong effects for fatness in pigs have been found on pig chromosome 4 which has synteny with human chromosome 1q21-32. We are currently attempting to refine the position of this gene using linkage analysis with other microsatellite markers from this region of the genome. In addition we are screening other families in which obesity segregates for linkage to 1q31.

    Full Text Available Background/Aims: It is well established that obesity is a strongly associated risk factor for post-operative deep vein thrombosis (DVT. Physical effects and pro-thrombotic, pro-inflammatory and hypofibrinolytic effects of severe obesity may predispose to idiopathic DVT (pre-operatively because of which bariatric patients are routinely screened before surgery. The aim of this study was to audit the use of routine screening venous duplex ultrasound in morbidly obese patients before undergoing bariatric surgery. Methods: We retrospectively reviewed 180 patients who underwent bariatric surgery from August 2013 to August 2014 who had undergone pre-operative screening bilateral lower-extremity venous duplex ultrasound for DVT. Data were collected on patient's demographics, history of venous thromboembolism, prior surgeries and duplex ultrasound details of the status of the deep veins and superficial veins of the lower limbs. Results: No patients had symptoms or signs of DVT pre-operatively. No patient gave history of DVT. No patient was found to have iliac, femoral or popliteal vein thrombosis. Superficial venous disease was found in 17 (8%. One patient had a right lower limb venous ulcer. Conclusion: Thromboembolic problems in the morbidly obese before bariatric surgery are infrequent, and screening venous duplex ultrasound can be done in high-risk patients only.

  9. Utility of the ELF Test for Detecting Steatohepatitis in Morbid Obese Patients with Suspicion of Nonalcoholic Fatty Liver Disease.

    Morbid obese patients have a high rate of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). NASH is related to the progression and poor evolution of chronic hepatopathy in NAFLD, so that its detection makes it possible to identify the subjects who are most at risk in order to prioritize treatment. The ELF test (Enhanced Liver Fibrosis test; Siemens Diagnostics, NY, USA) has been assessed for its capacity to detect fibrosis in patients with NAFLD, but its capacity for diagnosing NASH has not been checked. Our objective is to determine the utility of the ELF test for detecting NASH in morbid obese patients with suspected NAFLD. ELF values were determined in a cohort of obese patients who underwent bariatric surgery with suspected NAFLD. Liver biopsy was used as the reference standard. The values of ELF were significantly higher in patients with NASH (p = 0.002) and in those who presented with metabolic syndrome (p = 0.047). An ELF cut-off point of 8.72 allows the detection of patients with NASH with a sensitivity of 71.4% and a specificity of 74.1% (AUC = 0.742, p = 0.002). The ELF test is efficient for the identification of obese patients with NAFLD and early signs of steatohepatitis and fibrosis.

    To compare neonatal outcomes following deliveries 39 weeks after confirmation of fetal lung maturity with scheduled deliveries ≥39 weeks. A retrospective cohort study examining neonatal outcomes of women who were delivered following documented fetal pulmonary maturity at 36, 37, and 38 weeks compared to women undergoing a scheduled delivery at 39, 40, and 41 weeks. The χ(2)-test and Student's t-test were used to compare categorical and continuous data, respectively. Delivery prior to 39 weeks following fetal pulmonary maturity was associated with a 8.4% composite neonatal morbidity rate as compared to 3.3% for deliveries at 39 weeks or greater (relative risk [RR] 2.9; confidence interval [CI] 2.4-3.6). Neonatal respiratory morbidity was significantly higher (5.4%) for those delivering at less than 39 weeks with documented fetal pulmonary maturity as compared to 2.1% for those delivering at 39 weeks or greater (RR 3.0; CI 2.3-3.9). Increased neonatal morbidity persisted for those delivered prior to 39 weeks even after excluding all diabetics (p 39 weeks regardless of the mode of delivery. Despite fetal pulmonary maturity, delivery before 39 weeks is associated with significantly increased neonatal morbidity when compared to scheduled deliveries at 39 weeks or greater.

  13. Relevance of Adipose Tissue Stiffness Evaluated by Transient Elastography (AdipoScan™) in Morbidly Obese Patients before Bariatric Surgery

    Sasso, Magali; Abdennour, Meriem; Liu, Yuejun; Hazrak, Hecham; Aron-Wisnewsky, Judith; Bouillot, Jean-Luc; Le Naour, Gilles; Bedossa, Pierre; Torjman, Joan; Clément, Karine; Miette, Véronique

    Subcutaneous adipose tissue (scAT) in human obesity undergoes severe alteration such as fibrosis which is related to metabolic alterations and to less efficiency in losing weight after bariatric surgery. There is currently no non-invasive tool to assess fibrosis in scAT. Vibration Controlled Transient Elastography (VCTE) using FibroScan® is widely used to assess liver fibrosis in clinical practice. A novel device named AdipoScan™ which is based on VCTE has been developed by Echosens (Paris) so as to assess scAT. The objective of this study is to show the first AdipoScan clinical results. AdipoScan™ was assessed in vivo on 73 morbidly obese patients candidate for bariatric surgery who were enrolled in the Pitié Salpêtrière hospital. scAT shear wave speed measured by AdipoScan™ is significantly associated with scAT fibrosis, gender, hypertension status, total body fat mass assessed by DXA, hypertension status, glycemic, lipid, hepatic parameters and adiponectin. Results suggest that scAT evaluation before bariatric surgery can be useful in clinical practice since it is related to scAT fibrosis -who plays in role in weight loss resistance after bariatric surgery- and to obesity induced co-morbidities such as diabetes, hypertension liver dysfunction.

  14. Systemic Oxidative Stress Is Increased to a Greater Degree in Young, Obese Women Following Consumption of a High Fat Meal

    Richard J. Bloomer

    2009-01-01

    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.

    Few studies have assessed the impact of obesity on laparoscopic cholecystectomy (LC) in pediatric patients. Children who underwent LC were identified from the 2012 to 2013 American College of Surgeons' National Surgical Quality Improvement Program Pediatrics data. Patient characteristics, operative details, and outcomes were compared. Multivariable logistic regression was utilized to identify predictors of increased operative time (OT) and duration of anesthesia (DOAn). In total, 1757 patients were identified. Due to low rates of obesity in children obese). Among obese children, 80.6% were girls. A higher proportion of obese patients had diabetes (3.0% versus 1.0%, P obesity was an independent predictor of OT >90 (odds ratio [OR] 2.02; 95% confidence interval [95% CI] 1.55-2.63), and DOAn >140 minutes (OR 1.86; 95% CI 1.42-2.43). Obesity is an independent risk factor for increased OT in children undergoing LC. Pediatric surgeons and anesthesiologists should be prepared for the technical and physiological challenges that obesity may pose in this patient population.

    The aim of the present work was to investigate the role of ondansetron on the high fat diet (HFD) induced obese mice for behavioral and biochemical alterations using chronic unpredictable mild stress (CUMS) model of depression. Animals were fed with high fat diet for 14 weeks and subjected to different stress procedures for 4 weeks. Treatment with ondansetron was started on day 15. After day 28 behavioral assays and biochemical estimations were performed. Behavioral paradigms viz. sucrose preference test, locomotor score, forced swim test (FST) and elevated plus maze (EPM), whereas biochemical parameters like plasma glucose, total cholesterol, triglycerides and total proteins were estimated. Results examines that in behavioral assays, ondansetron significantly (P glucose, total cholesterol, triglycerides and total proteins were significantly (P glucose level indicates that, it could be "altered glucose level" playing an important role in depression co-morbid with obesity. Ondansetron through allosteric modulation of serotonergic system elevates the serotonin level and thereby regulates the insulin secretion and hence, reversing the "altered glucose level", could be the possible antidepressive-like mechanism against depression co-morbid with obesity.

    Obesity is an increasingly common condition with serious associated morbidity and decreased life expectancy. Laparoscopic adjustable gastric banding (LAGB) has demonstrated its safety and efficacy as a surgical therapy for morbid obesity over the short term. The current study sought to determine the long-term safety and efficacy of a low-pressure LAGB. Between August 1996 and July 2007, 1,000 consecutive patients underwent LAGB implantation with the Swedish Adjustable Gastric Band (SAGB). This series was retrospectively reviewed with regard to weight loss and morbidity. Patients served as their own controls. Preoperatively, there were 808 women (81.0%) and 192 men (19.0%) with a mean age of 46 +/- 11 years (range 13-81 yrs) and mean body mass index (BMI) of 42.0 +/- 7.0 kg/m2 (range 27-82 kg/m2). At 1-, 3-, 6-, and 8-year follow-up, mean percent excess weight loss was 41% (n = 600), 56% (n = 367), 51% (n = 114), and 52% (n = 43), respectively. At the same time points, BMI decreased, from 42.0 to 31.0, 32.5, and 30.5 kg/m2, respectively. Complications occurred in 197 patients. There were 2 operative complications (i.e., stomach perforation and vascular injury) and 25 conversions (2.4%) to open surgery. Major and minor wound infection in the perioperative period occurred in 47 (4.7%) and 43 (4.3%) patients, respectively. There was 1 death from a myocardial infarct 1 week after surgery. Long term, there were 30 (3.0%) band slippages, 31 (3.1%) erosions, 67 (6.7%) port problems, and 12 (1.2%) incisional hernias. LAGB with the SAGB is effective in achieving a mean sustainable weight loss of >50% at 8 years after surgery, with an acceptably low morbidity.

    2008-01-18

    Ectopic ovarian tissue is an unusual entity, especially if it is an isolated finding thought to be of embryological origin. An 11-year-old, morbidly obese female presented with left flank pain, nausea, and irregular menses. Various diagnostic procedures suggested a large ovarian cyst, and surgical resection was performed. Histologically, the resected mass was not of tubal origin as suspected, but a serous cystadenoma arising from ovarian tissue. The patient's two normal, eutopic ovaries were completely uninvolved and unaffected. A tumor arising from ectopic ovarian tissue of embryological origin seems the most likely explanation. We suggest refining the descriptive nomenclature so as to more precisely characterize the various presentations of ovarian ectopia.

    2013-01-01

    Full Text Available Background: Obesity once thought the medical problem of affluent countries now exist in Nigeria and has been described as a time bomb for the future explosion in the frequency of cardio-metabolic diseases. The most deleterious health consequences of obesity are on the cardiovascular system and associated disorder of lipid and glucose homeostasis. Aim: This study was designed to determine the magnitude of obesity and its cardio-metabolic co-morbidities among adult Nigerians in a primary care clinic of a tertiary hospital South-Eastern, Nigeria. Materials and Methods: A cross-sectional study carried out on 2391 adult Nigerians who were assessed for obesity using body mass index (BMI criterion. 206 patients who had BMI ΃30kg/m 2 were screened for cardio-metabolic co-morbidities. The data collected included basic demographic variables, weight, height, blood pressure; fasting plasma glucose and lipid profile. Results: The prevalence of obesity was 8.6%. Grade I obesity (67.5% was the most common pattern; others included grade II obesity (23.3% and grade III obesity (9.2%. Hypertension (42.7% was the most common cardio-metabolic morbidity. Others included low HDL-cholesterol (22.8%, diabetes mellitus (15.1%, high triglyceride (12.6%, high total cholesterol (9.2%, and high LDL-cholesterol (6.8%. Conclusion: Obesity and its cardio-metabolic morbidities exist among the study population. Anthropometric determination of obesity and screening for its associated cardio-metabolic co-morbidities should constitute clinical targets for intervention in primary care clinics.

    Although preoperative fluid intake 2 hours before anesthesia is generally considered safe, there are concerns about delayed gastric emptying in obese subjects. In this study, the gastric fluid volume (GFV) change in morbidly obese subjects was investigated after ingesting an oral rehydration solution (ORS) and then compared with that in nonobese subjects. GFV change over time after the ingestion of 500 mL of ORS containing 2.5% carbohydrate (OS-1) was measured in 10 morbidly obese subjects (body mass index [BMI], >35) scheduled for bariatric surgery and 10 nonobese (BMI, 19-24) using magnetic resonance imaging. After 9 hours of fasting, magnetic resonance imaging scans were performed at preingestion, 0 min (just after ingestion), and every 30 minutes up to 120 minutes. GFV values were compared between morbidly obese and control groups and also between preingestion and postingestion time points. The morbidly obese group had a significantly higher body weight and BMI than the control group (mean body weight and BMI in morbidly obese, 129.6 kg and 46.3 kg/m, respectively; control, 59.5 kg and 21.6 kg/m, respectively). GFV was significantly higher in the morbidly obese subjects compared with the control group at preingestion (73 ± 30.8 mL vs 31 ± 19.9 mL, P = .001) and at 0 minutes after ingestion (561 ± 30.8 mL vs 486 ± 42.8 mL; P < .001). GFV declined rapidly in both groups and reached fasting baseline levels by 120 minutes (morbidly obese, 50 ± 29.5 mL; control, 30 ± 11.6 mL). A significant correlation was observed between preingestion residual GFV and body weight (r = .66; P = .001). Morbidly obese subjects have a higher residual gastric volume after 9 hours of fasting compared with subjects with a normal BMI. However, no differences were observed in gastric emptying after ORS ingestion in the 2 populations, and GFVs reached baseline within 2 hours after ORS ingestion. Further studies are required to confirm whether the preoperative fasting and fluid

  4. Rotavirus Gastroenteritis is Associated with Increased Morbidity and Mortality in Children with Inherited Metabolic Disorders

    Smith, A

    2017-04-01

    Rotavirus is the leading cause of infantile diarrhoea worldwide in children <5 years1. Although mortality rates are low in Ireland, certain populations are more susceptible to the associated morbidity and mortality of infection. A retrospective chart review of 14 patients with confirmed IMDs who were admitted to Temple Street Children’s Hospital between 2010 to 2015 with rotavirus infection were compared with 14 randomly selected age matched controls. The median length of stay was 7 days (SD25.3) in IMD patients versus 1.5 days (SD 2.1) in the controls. IV fluids were required on average for 4.5 days (range 0-17) in IMD patients versus 0.63 days (range 0-3) in controls. This report highlights the increased morbidity of rotavirus infection in patients with IMD compared to healthy children. This vulnerable population are likely to benefit from the recent introduction of the rotavirus oral vaccination in October 2016.

  6. Effect of Laparoscopic Adjustable Gastric Banding on Metabolic Syndrome and Its Risk Factors in Morbidly Obese Adolescents

    Rushika Conroy

    2011-01-01

    Full Text Available We examined the effect of laparoscopic adjustable gastric banding (LAGB on weight loss, inflammatory markers, and components of the Metabolic Syndrome (MeS in morbidly obese adolescents and determined if those with MeS lose less weight post-LAGB than those without. Data from 14–18 yr adolescents were obtained at baseline, 6 and 12 months following LAGB. Significant weight loss and improvements in MeS components were observed 6 months and one year following LAGB. The incidence of MeS declined 56.8% after 6 months and 69.6% after 12 months. There was no significant difference in amount of weight lost post-LAGB between those with and without MeS at either timepoint. Correlations between change in weight parameters and components of MeS in those with and without MeS at baseline were examined and found to vary by diagnostic category. LAGB is effective for short-term improvement in weight, inflammatory markers, and components of MeS in morbidly obese adolescents.

    Full Text Available Objective: The objective was to estimate the prevalence of inadequate vitamin D status and secondary hyperparathyroidism (SHPT in morbidly obese patients and in patients who underwent biliopancreatic diversion/duodenal switch surgery (BPD/DS Design: 3 groups were included in the cross-sectional comparative study: group 1 - morbidly obese (MO patients with BMI > 40 and without type 2 diabetes mellitus (n=22, group 2 – patients in the long-term period after BPD/DS (n=23; group 3 – healthy normal weight controls (n=22. Results: 25(OHD levels were significantly different in the controls (21.8 ng/dl, in the MO (8.8 ng/dl and in the BPD/DS patients (8.6 ng/dl. Parathyroid hormone (PTH elevation was found in 4 (18% MO patients, in 12 (52 % patients after BPD/DS, and was not detected in the control group. The frequency of SHPT was significantly higher in the operated group (52 % in comparison with the MO group (18 % (р=0.029. Conclusions: Vitamin D deficiency and secondary hyperparathyroidism are significantly more prevalent in MO patients than in normal weight subjects. In the long-term period after BPD secondary hyperthyroidism is more frequent than in MO and is not always accompanied by vitamin D depletion. Special attention should be paid for adequate control of calcium metabolism and supplementation by calcium and vitamin D.

    Gallart-Aragón, Tania; Fernández-Lao, Carolina; Cózar-Ibañez, Antonio; Cantarero-Villanueva, Irene; Cambil-Martín, Jacobo; Jiménez Ríos, José Antonio; Arroyo-Morales, Manuel

    2017-12-29

    The objective of our study is to analyze the possible relationship between changes in glycemic profile and body composition parameters in morbid obesity patients after tubular laparoscopic gastrectomy. A prospective observational cohort study with 69 patients was performed. The variables analyzed were body weight, blood glucose, hemoglobin, glycosylated, high density lipoprotein, low density lipoprotein, triglycerides, and waist and hip circumference. An analysis of variance of repeated measurements (ANOVA) and a correlation analysis through the Pearson test were carried out. A significant reduction in weight (p<.001 after surgery) and in glycosylated hemoglobin (p<.036) and waist hip (p<.001) were found at 6 months after surgery. There was no significant difference in the rest of the variables studied. In correlation analysis, a significant positive correlation was found between the change in concentration of hemoglobin glycosylated and hip circumference (p=.047; r=0.237), the smaller the hip circumference, the lower the concentration of glycosylated hemoglobin. Tubular laparoscopic gastrectomy is an effective technique for the treatment of morbidly obese patients with type 2 diabetes mellitus. The reduction in the perimeter of hip is related to glycosylated hemoglobin reduction 6 months after intervention. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Obesity and osteoporosis are two common diseases with an increasing prevalence and a high impact on morbidity and mortality. Obese women have always been considered protected against osteoporosis and osteoporotic fractures. However, several recent studies have challenged the widespread belief that obesity is protective against fracture and have suggested that obesity is a risk factor for certain fractures.

  10. From morbid obesity to a healthy weight using cognitive-behavioral methods: a woman's three-year process with one and one-half years of weight maintenance.

    Annesi, James J; Tennant, Gisèle A

    2012-01-01

    Obesity is a national health problem regularly confronting medical professionals. Although reduced-energy (kilocalorie [kcal]) eating and increased exercise will reliably reduce weight, these behaviors have been highly resistant to sustained change. To control eating using theory-based cognitive-behavioral methods that leverage the positive psychosocial effects of newly initiated exercise as an alternate to typical approaches of education about appropriate nutrition. A woman, age 48 years, with morbid obesity initiated exercise through a 6-month exercise support protocol based on social cognitive and self-efficacy theory (The Coach Approach). This program was followed by periodic individual meetings with a wellness professional intended to transfer behavioral skills learned to adapt to regular exercise, to then control eating. There was consistent recording of exercises completed, foods consumed, various psychosocial and lifestyle factors, and weight. Over the 4.4 years reported, weight decreased from 117.6 kg to 59.0 kg, and body mass index (BMI) decreased from 43.1 kg/m(2) to 21.6 kg/m(2). Mean energy intake initially decreased to 1792 kcal/day and further dropped to 1453 kcal/day by the end of the weight-loss phase. Consistent with theory, use of self-regulatory skills, self-efficacy, and overall mood significantly predicted both increased exercise and decreased energy intake. Morbid obesity was reduced to a healthy weight within 3.1 years, and weight was maintained in the healthy range through the present (1.3 years later). This case supports theory-based propositions that exercise-induced changes in self-regulation, self-efficacy, and mood transfer to and reinforce improvements in corresponding psychosocial factors related to controlled eating.

    Non-invasive cardiac imaging may suffer from poor image quality in morbidly obese individuals. This study aimed to determine the clinical value of contemporary stress echocardiography (SE) in morbidly obese patients referred for assessment of suspected coronary artery disease (CAD). This prospective, multicentre observational study was conducted in two district hospitals and one tertiary centre in London, UK. Individuals with body mass index ≥35 kg/m(2) referred for SE were evaluated. The percentage of patients with obstructive CAD on coronary angiography, following abnormal SE, was assessed. Patient outcomes were determined with follow-up for the composite end-point of all-cause mortality, myocardial infarction and late revascularisation. Over a 13-month period, 209 morbidly obese patients underwent SE, and contrast agent was used in 96% of patients. A diagnostic result was obtained in 200/209 (96%) patients. Of 32 (15%) patients with inducible ischaemia, 25 underwent angiography, 22 (88%) had corresponding significant CAD and, of these, 16 (77%) underwent revascularisation. Conversely, only 2/157 patients (1.3%) with normal SE underwent angiography, and none underwent revascularisation. Over a mean follow-up period of 17.8±5.4 months, there were nine events. The annualised cardiac event rate after a normal SE was 0.95%. Events were more frequent in patients with inducible ischaemia versus those without ischaemia (5/32 (15.6%) vs 4/153 (2.6%); p=0.002). Ejection fraction <50% (HR 9.5; 95% CI 2.4 to 38.0; p=0.002) and inducible ischaemia (HR 9.4; 95% CI 2.5 to 35.8; p=0.001) were predictors of outcome on univariable Cox regression analysis. Contemporary SE has excellent feasibility and positive predictive value and resulted in appropriate risk stratification of symptomatic patients with significant obesity. A normal SE portends an excellent outcome over the short-intermediate term in this high-risk patient population. Published by the BMJ Publishing Group

    2006-03-01

    Although obesity predisposes to postoperative pulmonary complications, data on the relationship between body mass index (BMI) and peri-operative respiratory performance are limited. We prospectively studied the impact of spinal anaesthesia, obesity and vaginal surgery on lung volumes measured by spirometry in 28 patients with BMI 30-40 kg.m(-2) and in 13 patients with BMI > or = 40 kg.m(-2). Vital capacity, forced vital capacity, forced expiratory volume in 1 s, mid-expiratory and peak expiratory flows were measured during the pre-operative visit (baseline), after effective spinal anaesthesia with premedication, and after the operation at 20 min, 1 h, 2 h, and 3 h (after mobilisation). Spinal anaesthesia and premedication were associated with a significant decrease in spirometric parameters. Spinal anaesthesia and premedication were associated with a significant decrease in spirometric parameters; mean (SD) vital capacities were - 19% (6.4) in patients with BMI 30-40 kg.m(-2) and - 33% (9.0) in patients with BMI > 40 kg.m(-2). The decrease of lung volumes remained constant for 2 h, whereas 3 h after the operation and after mobilisation, spirometric parameters significantly improved in all patients. This study showed that both spinal anaesthesia and obesity significantly impaired peri-operative respiratory function.

    Exercise is potentially protective against cancer for obese women. The objectives were to examine differences in activity, body composition, and hormones in overweight/obese women with and without endometrial cancer. Women ≥ 50 years old with a body mass index (BMI) ≥ 25 kg/m(2) scheduled for abdominal hysterectomy were enrolled. Demographics, physical activity, and quality of life (QOL) data were collected. Body composition/fitness was evaluated using Air Displacement Plethysmography (BodPod) and a standardized treadmill. Adiponectin, androstenedione, leptin, estradiol, estrone, progesterone, sex hormone binding globulin, insulin and glucose were measured. Thirty-eight women enrolled in this pilot study; 22 had endometrial cancer. Mean age was 58.3 years, mean BMI, fat weight and percent body fat were 41.3 kg/m(2), 55 kg and 51% respectively. Fitness levels were poor; 90% of women had peak oxygen uptakes below the 10th percentile of population normals yet 80% still rated their fitness level as equivalent to other women. Women with and without cancer did not differ in age, BMI, co-morbidities, energy expenditures, body composition, hormones or QOL although glucose levels were higher in women with cancer (119.5 vs. 90.7 mg/dl; p=0.049). Cancer subjects scored worse on every fitness measurement, reaching statistical significance for VO(2 peak) (15.0 vs. 17.9 ml/kg/min; p=0.033). Current exercisers had a lower BMI (p=0.039), decreased fat weight (p=0.024), decreased waist circumference (p=0.05) and improved vitality compared to non-exercisers.

  15. Eating styles in the morbidly obese: restraint eating, but not emotional and external eating, predicts dietary behaviour.

    Brogan, Amy; Hevey, David

    2013-01-01

    The research explored (1) the relationships between self-reported eating style (restraint, emotional and external eating) and dietary intake and (2) emotional eater status as a moderator of food intake when emotional, in a morbidly obese population. A sample of 57 obese participants (BMI: M = 51.84, SD = 8.66) completed a five-day food diary together with a reflective diary, which assessed eating style and positive and negative affect daily. A dietician-scored food pyramid analysis of intake. Restraint eating was the only predictor (negative) of overall food intake and the variable most strongly associated with the consumption of top-shelf foods. Emotional and external eating were unrelated to food intake. Emotional eater status did not moderate food intake in response to positive and negative mood states. The findings indicated largely analogous relationships between eating style and dietary intake in this obese sample compared with previous results from healthy populations. The lack of predictive validity for emotional eating scales (when emotional) raises questions over people's ability to adequately assess their eating style and consequently, the overall validity of emotional eater scales.

    The incidence of overweight and obesity has been steadily on the rise and has reached epidemic proportions in various countries and this represents a well-known major health problem. Nevertheless, current guidelines for resuscitation do not include special sequences of action in this subset of patients. The aim of this letter is to bring this controversy into focus and to suggest alterations of the known standard cardiopulmonary resuscitation in the obese. An obese patient weighing 272 kg fell to the floor, afterwards being unable to get up again. Thus, emergency services were called for assistance. There were no signs or symptoms signifying that the person had been harmed in consequence of the fall. Only when brought into a supine position the patient suffered an immediate cardiac arrest. Cardiopulmonary resuscitation was performed but there was no return of a stable spontaneous circulation until the patient was brought into a full lateral position. In spite of immediate emergency care the patient ultimately suffered a lethal hypoxic brain damage. A full lateral position should be considered in obese patients having a cardiac arrest as it might help to re-establish stable circulatory conditions.

    With over 110,000 bariatric operations performed in the United States annually, it is important to understand the biochemical abnormalities causing endocrine dysfunction associated with these procedures. Here we compare 2 malabsorptive procedures, duodenal switch and Roux-en-Y gastric bypass, to determine the role malabsorption plays in secondary hyperparathyroidism in this population. Data from all super-obese patients undergoing duodenal switch or Roux-en-Y gastric bypass between August 2002 and October 2005 were prospectively collected. Postoperatively, all patients received 1,200 mg of calcium citrate and 1,000 IU vitamin D3 per American Society for Metabolic and Bariatric Surgery guidelines. Beginning in 2007, duodenal switch patients were instructed to add daily vitamin D3 10,000 IU. Statistical analyses included Student t test, multivariate, and univariate logistic regression. Of 283 patients with a body mass index ≥50, 170 (60.1%) underwent duodenal switch, while 113 (39.9%) underwent Roux-en-Y gastric bypass. Of 132 (46.6%) patients with secondary hyperparathyroidism, 101 (59.4%) had undergone duodenal switch and 31 (27.4%) had undergone Roux-en-Y gastric bypass. Symptoms were more common in the duodenal switch group (33 patients [19.4%]) than Roux-en-Y gastric bypass (11 patients [9.7%]). Multivariate logistic regression demonstrated that the extent of bypass and duration of follow-up were the only 2 independent predictive risk factors for developing secondary hyperparathyroidism. Although vitamin D levels improved with increased vitamin D3 supplementation in 2007, rates of secondary hyperparathyroidism increased. Despite routine postoperative calcium and vitamin D3 supplementation, secondary hyperparathyroidism is common after Roux-en-Y gastric bypass and duodenal switch. The degree of iatrogenic malabsorption correlates with the incidence of secondary hyperparathyroidism. These rates suggest current supplementation guidelines are not sufficient in

    Obesity is associated with increased hepatic glycogen content. In vivo and in vitro data suggest that plasma free fatty acids (FFA) may cause this increase. In this study we investigated the effect of physiological plasma FFA levels on hepatic glycogen metabolism by studying intrahepatic glucose

  3. [Impact of obesity in the pathophysiology of degenerative disk disease and in the morbidity and outcome of lumbar spine surgery].

    Delgado-López, Pedro David; Castilla-Díez, José Manuel

    Obesity (BMI>30Kg/m 2 ) is a pandemic with severe medical and financial implications. There is growing evidence that relates certain metabolic processes within the adipose tissue, preferentially abdominal fat, with a low-intensity chronic inflammatory state mediated by adipokines and other substances that favor disk disease and chronic low back pain. Obesity greatly conditions both the preoperative evaluation and the spinal surgical technique itself. Some meta-analyses have confirmed an increase of complications following lumbar spine surgery (mainly infections and venous thrombosis) in obese subjects. However, functional outcomes after lumbar spine surgery are favorable although inferior to the non-obese population, acknowledging that obese patients present with worse baseline function levels and the prognosis of conservatively treated obese cohorts is much worse. The impact of preoperative weight loss in spine surgery has not been prospectively studied in these patients. Copyright © 2017 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    2018-01-16

    Sleeve gastrectomy is increasingly used in the treatment of morbid obesity, but its long-term outcome vs the standard Roux-en-Y gastric bypass procedure is unknown. To determine whether there are differences between sleeve gastrectomy and Roux-en-Y gastric bypass in terms of weight loss, changes in comorbidities, increase in quality of life, and adverse events. The Swiss Multicenter Bypass or Sleeve Study (SM-BOSS), a 2-group randomized trial, was conducted from January 2007 until November 2011 (last follow-up in March 2017). Of 3971 morbidly obese patients evaluated for bariatric surgery at 4 Swiss bariatric centers, 217 patients were enrolled and randomly assigned to sleeve gastrectomy or Roux-en-Y gastric bypass with a 5-year follow-up period. Patients were randomly assigned to undergo laparoscopic sleeve gastrectomy (n = 107) or laparoscopic Roux-en-Y gastric bypass (n = 110). The primary end point was weight loss, expressed as percentage excess body mass index (BMI) loss. Exploratory end points were changes in comorbidities and adverse events. Among the 217 patients (mean age, 45.5 years; 72% women; mean BMI, 43.9) 205 (94.5%) completed the trial. Excess BMI loss was not significantly different at 5 years: for sleeve gastrectomy, 61.1%, vs Roux-en-Y gastric bypass, 68.3% (absolute difference, -7.18%; 95% CI, -14.30% to -0.06%; P = .22 after adjustment for multiple comparisons). Gastric reflux remission was observed more frequently after Roux-en-Y gastric bypass (60.4%) than after sleeve gastrectomy (25.0%). Gastric reflux worsened (more symptoms or increase in therapy) more often after sleeve gastrectomy (31.8%) than after Roux-en-Y gastric bypass (6.3%). The number of patients with reoperations or interventions was 16/101 (15.8%) after sleeve gastrectomy and 23/104 (22.1%) after Roux-en-Y gastric bypass. Among patients with morbid obesity, there was no significant difference in excess BMI loss between laparoscopic sleeve gastrectomy and laparoscopic Roux

  7. Relationship between urban sprawl and physical activity, obesity, and morbidity - update and refinement.

    Ewing, Reid; Meakins, Gail; Hamidi, Shima; Nelson, Arthur C

    2014-03-01

    This study aims to model multiple health outcomes and behaviors in terms of the updated, refined, and validated county compactness/sprawl measures. Multiple health outcomes and behaviors are modeled using multi-level analysis. After controlling for observed confounding influences, both original and new compactness measures are negatively related to BMI, obesity, heart disease, high blood pressure, and diabetes. Indices are not significantly related to physical activity, perhaps because physical activity is not defined broadly to include active travel to work, shopping, and other destinations. Developing urban and suburban areas in a more compact manner may have some salutary effect on obesity and chronic disease trends. Copyright © 2013 The Authors. Published by Elsevier Ltd..

    The fat mass and obesity-related ( FTO ) gene has a strong relationship with obesity, extreme obesity and inflammatory state, and may also be associated with food intake regulation. The aim of the present study was to evaluate the influence of the rs9939609 single-nucleotide polymorphism of the FTO gene on appetite, ghrelin, leptin, interleukin 6 (IL6), tumor necrosis factor α (TNFα) levels and food intake of morbidly obese women. The study comprised 70 women, aged between 20 and 48 years, from Rio de Janeiro, Brazil. The participants were selected according to the body mass index between 40 and 60 kg/m 2 . Anthropometric and biochemical data were measured during fasting. Hormones and inflammatory data were measured before and after the participants ate an isocaloric meal. Dietary records were calculated and analyzed using a nutritional assessment program. Visual analog scales were used for behaviors of the sensations of appetite and food preferences. The FTO rs9939609 variant was genotyped using real-time polymerase chain reaction. Participants with the AA genotype had lower values of ghrelin and IL6 and higher values of leptin than those with TT and TA in the postprandial period. Comparing the plasma concentrations of ghrelin, insulin, IL6 and TNFα intragenotypes, it was observed that those with TT had decreased leptin and increased IL6 at the postprandial period. Subjects with TA showed increased postprandial IL6, and those with AA had decreased postprandial ghrelin. There was no difference in TNFα intra- and intergenotypes. The postprandial sensations of hunger were lower in AA than those with TT. There were differences between genotypes regarding ingested grams of protein by weight, cholesterol, B3, B5, B6 and B12 vitamins, and selenium potassium and sodium minerals. These findings suggest that genetics may exert an influence on physiologic factors and might alter eating behavior.

    2001-09-01

    Overweight can be a risk factor for pathological gastroesophageal reflux or hiatal hernia. To study the prevalence of gastroesophageal reflux in patients with severe obesity. Sixty seven patients, 51 female, aged 17 to 56 years old with a body mass index over 35 kg/m2, were studied. An upper gastrointestinal endoscopy was performed in all, esophageal manometry was done in 32 and 24 h pH monitoring was done in 32 patients. Seventy nine percent of patients complained of heartburn and 66% of regurgitation. In 16 patients, endoscopy was normal. An erosive esophagitis was found in 33 patients, a short columnar epithelium in 12 and a Barret esophagus with intestinal metaplasia in six. Normal endoscopic findings and erosive esophagitis were present with a higher frequency in women. No association between the degree of obesity and esophageal lesions was observed. Lower esophageal sphincter pressure and abdominal length were significantly higher in subjects with a body mass index over 50 compared to those with a body mass index between 35 and 39.9 kg/m2. No differences were observed in 24 h pH monitoring. A high proportion of severely obese patients had symptoms and endoscopical findings of pathological gastroesophageal reflux.

    Body mass index has been associated with ischemic stroke in older populations, but its association with stroke in younger populations is not known. In light of the current obesity epidemic in the United States, the potential impact of obesity on stroke risk in young adults deserves attention. A population-based case-control study design with 1201 cases and 1154 controls was used to investigate the relationship of obesity and young onset ischemic stroke. Stroke cases were between the ages of 15 and 49 years. Logistic regression analysis was used to evaluate the association between body mass index and ischemic stroke with and without adjustment for comorbid conditions associated with stroke. In analyses adjusted for age, sex, and ethnicity, obesity (body mass index >30 kg/m(2)) was associated with an increased stroke risk (odds ratio, 1.57; 95% confidence interval, 1.28-1.94) although this increased risk was highly attenuated and not statistically significant after adjustment for smoking, hypertension, and diabetes mellitus. These results indicate that obesity is a risk factor for young onset ischemic stroke and suggest that this association may be partially mediated through hypertension, diabetes mellitus, or other variables associated with these conditions. © 2015 American Heart Association, Inc.

  11. Perioperative management of a morbidly obese pregnant patient undergoing cesarean section under general anesthesia – case report

    2016-07-01

    Full Text Available Background and objectives: The increased prevalence of obesity in the general population extends to women of reproductive age. The aim of this study is to report the perioperative management of a morbidly obese pregnant woman, body mass index >50 kg/m2, who underwent cesarean section under general anesthesia. Case report: Pregnant woman in labor, 35 years of age, body mass index 59.8 kg/m2. Cesarean section was indicated due to the presumed fetal macrosomia. The patient refused spinal anesthesia. She was placed in the ramp position with cushions from back to head to facilitate tracheal intubation. Another cushion was placed on top of the right gluteus to create an angle of approximately 15° to the operating table. Immediately before induction of anesthesia, asepsis was carried out and sterile surgical fields were placed. Anesthesia was induced in rapid sequence, with Sellick maneuver and administration of remifentanil, propofol, and succinilcolina. Intubation was performed using a gum elastic bougie, and anesthesia was maintained with sevoflurane and remifentanil. The interval between skin incision and fetal extraction was 21 min, with the use of a Simpson's forceps scoop to assist in the extraction. The patient gave birth to a newborn weighing 4850 g, with Apgar scores of 2 in the 1st minute (received positive pressure ventilation by mask for about 2 min and 8 in the 5th minute. The patient was extubated uneventfully. Multimodal analgesia and prophylaxis of nausea and vomiting was performed. Mother and newborn were discharged on the 4th postoperative day. Resumo: Justificativa e objetivos: O aumento na prevalência da obesidade na população geral se estende para mulheres na idade reprodutiva. O objetivo deste estudo é relatar o controle perioperatório de uma gestante obesa mórbida com índice de massa corporal >50 Kg/m2, submetida a parto cesariano sob anestesia geral. Relato do caso: Gestante de 35 anos com índice de massa corporal

    Andersen, T; Pedersen, B H; Henriksen, Jens Henrik Sahl

    1988-01-01

    This study investigated possible determinants of food intake change after gastroplastry. Preoperatively and 6 and 12 months postoperatively, 27 morbidly obese patients were prospectively examined with 7-day food registration and radiologic measurement of pouch volume and stoma diameter. Pouch...... associated with the change of solid foods consumed (by weight, p = 0.01; by energy content, p = 0.02). The change of pouch volume was negatively associated with the change of energy from beverages (p = 0.005). In conclusion, it seems impossible to tailor the reduction of food intake through adjustments...... emptying was determined as the mean transit time by a scintigraphic method. None of the measured variables was found to influence the change in food intake taking place during the first 6 months, when most of the weight loss was observed. Between 6 and 12 months, the change of stoma diameter was positively...

  13. Giant serous cystadenoma arising from an accessory ovary in a morbidly obese 11-year-old girl: a case report

    Sharatz Steven M

    2008-01-01

    Full Text Available Abstract Introduction Ectopic ovarian tissue is an unusual entity, especially if it is an isolated finding thought to be of embryological origin. Case presentation An 11-year-old, morbidly obese female presented with left flank pain, nausea, and irregular menses. Various diagnostic procedures suggested a large ovarian cyst, and surgical resection was performed. Conclusion Histologically, the resected mass was not of tubal origin as suspected, but a serous cystadenoma arising from ovarian tissue. The patient's two normal, eutopic ovaries were completely uninvolved and unaffected. A tumor arising from ectopic ovarian tissue of embryological origin seems the most likely explanation. We suggest refining the descriptive nomenclature so as to more precisely characterize the various presentations of ovarian ectopia.

    2015-01-01

    BACKGROUND AND AIMS: Macrophages play an important role in non-alcoholic fatty liver disease (NAFLD). Soluble CD163 (sCD163) is a specific marker of macrophage activation. We aimed to measure sCD163 in morbidly obese patients with varying degrees of NAFLD before and after bariatric surgery (BS...... (NAS), Kleiner fibrosis score, and the fatty liver inhibition of progression (FLIP) algorithm. In a subset, CD163 immunohistochemistry and real-time quantitative polymerase chain reaction for CD163 mRNA were performed. RESULTS: sCD163 was higher in patients with NAS ≥ 5 compared with those with NAS ...). METHODS: Demographic, clinical, and biochemical data, and plasma sCD163 measured by enzyme-linked immunosorbent assay, of 196 patients were collected preoperatively and 3, 6, and 12 months after BS leading to significant weight loss.

    obesity affects more than a third of Mexican population. Oxidative stress participates actively in the etiology of this phenomenon. Glutathione peroxidase-1 (GPX-1) plays a protective role against oxidative stress. The SNP Pro200Leu (rs10504050) has been reported to affect the activity of the enzyme. to determine the frequency of rs10504050 polymorphism in women with obesity and normal weight control, asses the concentration of peripheral TBARS and evaluate the consumption of pro and antioxidants. 104 women with obesity and 70 healthy controls (CG) were included in the study. Anthropometric, biochemical, clinical and dietary features were evaluated. GPx-1 rs10504050 was determined by PCR/RFLP method. TBARS was assayed spectrophotometrically in plasma. The subjects were stratified and compared by obesity grades and by subgroups of prediabetes and diabetes condition. Statistical analysis included ANOVA of Kruskal Wallis, Xi squared and Pearson correlation. for rs10504050 polymorphism there were differences (Xi2 = 6; p = 0.01) between frequency (0.61) of obese carriers (Pro/Leu plus Leu/Leu) and CG carriers (0.42), and between (Xi2 = 8; p = 0.004) morbid (IMC > 40) obesity (0.74) and CG carriers. The obese group (OB) showed a prevalence of 66% of prediabetes plus diabetes. There were no differences in frequencies of rs10504050 in OB with pre or diabetes versus CG, or versus obese participants without diabetes. TBARS concentration was greater in all the degrees of OB versus CG. GPx-1 Pro200Leu polymorphism was associated with obesity especially with morbid obesity, but not with obese participants with prediabetes or diabetes. Oxidative stress is present in all grades of obesity significantly. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

    Bariatric surgery is recognized as an effective treatment for type 2 diabetes mellitus, but data on its efficacy for type 1 diabetes mellitus, especially slowly progressive insulin-dependent diabetes mellitus, are limited. We investigated five Japanese patients with slowly progressive insulin-dependent diabetes mellitus who underwent bariatric surgery at our center. Five morbidly obese glutamic acid decarboxylase antibody-positive diabetic patients underwent two different types of bariatric surgery. The mean titer of anti-glutamic acid decarboxylase antibody was 4.6 U/mL, and the mean preoperative bodyweight and BMI were 113 kg and 39.6 kg/m 2 , respectively. The mean hemoglobin A1c was 8.4%. The mean fasting serum C-peptide was 5.0 ng/mL. Laparoscopic sleeve gastrectomy was performed in two patients, while laparoscopic sleeve gastrectomy with duodenojejunal bypass was performed in three patients. At one year after surgery, the mean bodyweight and BMI significantly dropped, and the mean percentage of excess weight loss was 96.4%. The mean hemoglobin A1c was 5.7%. This favorable trend was maintained at mid-term. Bariatric surgery for morbidly obese patients with anti-glutamic acid decarboxylase antibody-positive type 1 diabetes mellitus, especially slow progressive autoimmune diabetes, seemed effective in achieving mid-term glycemic control. Longer follow-up with a larger number of patients, as well as validation with more advanced patients with slowly progressive insulin-dependent diabetes mellitus, will be needed. © 2017 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

  17. The cost-effectiveness of laparoscopic adjustable gastric banding in the morbidly obese adult population of Australia.

    Yong Yi Lee

    Full Text Available BACKGROUND: To examine the cost-effectiveness of providing laparoscopic adjustable gastric banding (LAGB surgery to all morbidly obese adults in the 2003 Australian population. METHODS AND FINDINGS: Analyzed costs and benefits associated with two intervention scenarios, one providing LAGB surgery to individuals with BMI >40 and another to individuals with BMI >35, with each compared relative to a 'do nothing' scenario. A multi-state, multiple cohort Markov model was used to determine the cost-effectiveness of LAGB surgery over the lifetime of each cohort. All costs and health outcomes were assessed from an Australian health sector perspective and were discounted using a 3% annual rate. Uncertainty and sensitivity analyzes were conducted to test the robustness of model outcomes. Incremental cost-effectiveness ratios (ICERs were measured in 2003 Australian dollars per disability adjusted life year (DALY averted. The ICER for the scenario providing LAGB surgery to all individuals with a BMI >40 was dominant [95% CI: dominant -$588] meaning that the intervention led to both improved health and cost savings. The ICER when providing surgery to those with a BMI >35 was $2,154/DALY averted [95% CI: dominant -$6,033]. Results were highly sensitive to changes in the likelihood of long-term complications. CONCLUSION: LAGB surgery is highly cost-effective when compared to the $50,000/DALY threshold for cost-effectiveness used in Australia. LAGB surgery also ranks highly in terms of cost-effectiveness when compared to other population-level interventions for weight loss in Australia. The results of this study are in line with other economic evaluations on LAGB surgery. This study recommends that the Australian federal government provide a full subsidy for LAGB surgery to morbidly obese Australians with a BMI >40.

    The influence of different light regimes (constant light--LL; constant darkness--DD; standard light regime--LD, 12 hours light 12 hours darkness; natural lightening of the North-West of Russia--NL) on the dynamics of life's morbidity rate, spontaneous tumorigenesis and frequency of some kinds of non-tumor pathology revealed at the post-mortem examination of male rats was studied. It was found out that the maintenance of animals at LL and NL conditions led to the increase of the number of infectious diseases, substantially faster development of spontaneous tumors and the increase of non-tumor diseases in comparison with the animals kept at LD (standard light) regime. Light deprivation (DD) led to substantial reduction of development of new growth, of non-tumor and infectious diseases in comparison with the similar parameters in standard light regime.

    The objective of the study was to assess the interest, views and patient-perceived barriers to bariatric surgery among surgery-eligible patients. Surveys were completed at a weight management clinic and local hospital in Ontario, Canada. Patients were ≥18 years of age with a body mass index (BMI) >40 kg m(-2) or BMI > 35 kg m(-2) with ≥1 comorbidity. The sample included 105 participants, 73.3% female, with a mean BMI of 46.6 ± 7.1 kg m(-2) . Only 33.3% of participants were interested in surgery; 50.5% of participants were not interested and 16.2% had mixed feelings. Participants identified risks (69.5%) and side effects (57.1%) as significant surgical barriers. Interested participants were more likely to perceive themselves as obese, were unhappy with their current weight loss method and were less likely to fear surgery (P bariatric surgery, the majority of qualified patients are not interested in surgery mainly due to the perceived risk of surgery in general and satisfaction with current non-surgical weight loss efforts. The self-perception of obesity, as opposed to medical comorbidities, may be a stronger driver of the decision to have bariatric surgery. It is unclear if patients are aware of the effectiveness of bariatric surgery to help improve comorbidities or if bariatric surgery is perceived as being more cosmetic in nature. © 2016 World Obesity.

    transaminase (AST) levels. Finally, at the histological level KBP treatment reduced hepatic steatosis, ballooning and inflammation, hence resulting in a reduced NAS score in combination with a lowered fibrosis stage. In conclusion, KBPs induce and sustain weight loss, leading to improved metabolic parameters...... including food preference, and these are beyond those observed simply by dietinduced weight loss. Additionally, these peptides are well tolerated when introduced by dose escalation. Finally, KBPs reduce liver steatosis in both obese and NASH rats, and importantly reduced inflammation and fibrosis scores...

  1. Obesity increases airway hyperresponsiveness via the TNF-α pathway and treating obesity induces recovery.

    Joo Young Kim

    Full Text Available Obesity is a known risk factor for allergic asthma. It has been recognized as a key player in the pathogenesis of several inflammatory disorders via activation of macrophages, which is also vital to the development of allergic asthma. We investigated the mechanism of obesity-related asthma and whether treating obesity through exercise or diet ameliorates the severity of asthma in the obesity-related asthma model. We generated diet-induced obesity (DIO in C57BL/6 mice by high-fat-feeding and ovalbumin-induced asthma (lean-OVA or DIO-OVA. The DIO-OVA mice were then treated with tumor necrosis factor (TNF-α neutralizing antibody as a TNF-α blockade or a Cl2MDP-containing liposome to induce an alveolar macrophage deficiency. To treat obesity, the DIO-OVA mice were under dietary restrictions or exercised. The pathophysiological and immunological responses were analyzed. Airway hyperresponsiveness (AHR, serum IgE and TNF-α levels in the lung tissue increased in the DIO-OVA mice compared to the lean-OVA mice. Both the TNF-α blockade and depletion of alveolar macrophages in the DIO-OVA mice decreased AHR compared to the DIO-OVA mice. Treating obesity by exercise or through dietary means also reduced pulmonary TNF-α levels and AHR in the DIO-OVA mice. These results suggest that restoring normal body weight is an appropriate strategy for reducing TNF-α levels, and controlling inflammation may help improve asthma severity and control in obesity-related asthma.

    Although obesity affects all cultures, ethnic groups and social strata, this disorder affects African Americans, Hispanics and the poor at a disproportionate rate. The Downstart Pediatric Healthy Lifestyle Program was developed to provide a multi-disciplinary behavioral modification program for inner city families in Brooklyn, New York interested in leading a healthier, more active lifestyle. The Downstart Program uses a four-pronged approach of medical evaluation, exercise, nutritional education and lifestyle modification. A psychological evaluation is performed to determine the individual's ability and readiness to participate in group activities. Baseline physical fitness, flexibility and muscle strength are measured, followed by a twice-weekly karate/martial arts/dance program, incorporating principles established by the President's Council on Exercise. Nutritional and behavioral modification aspects of the program consist of weekly education about food groups, portion control, goal setting and appropriate rewards for attaining goals. Our preliminary results indicate that the Downstart Program may be a viable intervention for weight loss. Further study is needed to improve strategies for motivating patients and means and criteria for assessing long-term effects on health and lifestyle.

  4. Zinc nutritional status of morbidly obese patients before and after Roux-en-Y gastric bypass: a preliminary report.

    Cominetti, Cristiane; Garrido, Arthur Belarmino; Cozzolino, Silvia Maria Franciscato

    2006-04-01

    Previous researchers have found that the nutritional zinc status in obese and diabetic subjects is altered: low zinc concentrations in plasma and erythrocytes with high urinary zinc excretion were observed. This study assessed the influence of the Roux-en-Y gastric bypass (RYGBP) on the plasma, erythrocyte and urinary zinc concentrations before the beginning of the mineral supplementation. 24 morbidly obese patients were studied before and 2 months after RYGBP (the period in which the patients were still not ingesting mineral supplements). Fast blood sample, 24-hour urine, and 3-day food records were collected in the pre- and postoperative phases. Zinc concentration in the samples was analyzed by flame atomic absorption spectrophotometry, and dietary analysis of the food records were performed using the software Virtual Nutri with the inclusion of zinc concentration in the database for regional foods. Pre- and postoperative results were respectively: plasma 68.0 and 66.3 microg/dL; erythrocytes 36.6 and 43.8 microg/g Hb; urine 884.7 microg/24h and 385.9 microg/24h; and zinc intake 10.5 and 6.7 mg/day. These results suggest that RYGBP changed mainly the zinc erythrocyte and urinary concentrations. As expected, the zinc intake was lower in the postoperative phase, which in the medium and long term, could cause problems for the patients.

  5. Controversies in perioperative anesthetic management of the morbidly obese: I am a surgeon, why should I care?

    Sinha, Ashish C; Singh, Preet Mohinder

    2015-05-01

    Over the last four decades, as the rates of obesity have increased, so have the challenges associated with its anesthetic management. In the present review, we discuss perioperative anesthesia management issues that are modifiable by the early involvement of the surgical team. We sum up available evidence or expert opinion on issues like patient positioning, postoperative analgesia, and the effect of continuous positive airway pressure (CPAP) ventilation on surgical anastomosis. We also address established predictors of higher perioperative risk and suggest possible management strategies and concerns of obese patients undergoing same day procedures. Finally, a generalized pharmacological model relevant to altered pharmacokinetics in these patients is presented.

  8. Comparing men and women with binge-eating disorder and co-morbid obesity.

    Lydecker, Janet A; Grilo, Carlos M

    2018-03-01

    This study examined differences in clinical presentation of men and women with binge-eating disorder (BED) who participated in treatment research at a medical-school based program. Participants were 682 adults (n = 182 men, n = 500 women) with DSM-IV-defined BED. Doctoral-level research clinicians assessed eating-disorder psychopathology, including BED diagnosis, using the Structured Clinical Interview for DSM-IV Disorders (SCID) and Eating Disorder Examination (EDE) interview. Research clinicians measured height and weight and participants completed a battery of established self-report measures. Men had significantly higher body mass index (BMI) than women; women had significantly higher eating-disorder psychopathology (EDE scales and global score) and depression than men. Differences in eating-disorder psychopathology and depression remained higher for women than men after adjusting for race/ethnicity and BMI. Frequency of binge-eating episodes, subjective binge-eating episodes, and overeating episodes did not differ significantly by sex. Women had younger ages of onset for dieting and binge-eating behaviors than men but ages of onset for obesity and BED did not significantly differ between men and women. There are some sex differences in clinical presentation and age-of-onset timeline of adults with BED. Men and women develop obesity and BED (at diagnostic threshold) around the same age but women begin dieting and binge-eating behaviors earlier than men. At presentation for treatment for BED, men and women did not differ in binge-eating frequency and although men and women differed significantly on BMI and eating-disorder psychopathology, the magnitude of these differences was quite modest. © 2018 Wiley Periodicals, Inc.

    2018-02-08

    Masked hypertension is associated with an increased risk for cardiovascular conditions. The aim of the study was to evaluate the relationship obesity parameters, including body weight, waist circumference, and body mass index. The study group consisted of 251 consecutive outpatient subjects without overt hypertension. Subjects were classified according to BMI. After a complete medical history and laboratory examination, patients' height, weight, waist circumference heart rate, and office blood pressure were recorded. All subjects underwent ambulatory blood pressure monitoring. Masked hypertension is defined as normal office blood pressure measurement and high ambulatory blood pressure level. Baseline characteristics in patients and controls were similar. Prevalence of Masked hypertension was significantly higher in patients with obesity than controls (30.9% vs 5.7%, p < 0.001). Body mass index (33.2 ± 4.3 vs 25.1 ± 2.7 p < 0.001), waist circumference (98.5 ± 11.7 vs 86.8 ± 8.8, p < 0.001), and weight (86.5 ± 11.8 vs. 69 ± 9.1, p < 0.001) in patients with obesity were significantly higher than in patients with normal weight. Office Systolic BP (121.8 ± 4.4 vs 120.5 ± 4.78, p = 0.035), ambulatory daytime systolic BP (128.8 ± 8.9 vs 124.5 ± 7.4, p < 0.001), ambulatory daytime diastolic BP (73.9 ± 9.5 vs 71.5 ± 7.0, p = 0.019), ambulatory night-time systolic BP in patients with obesity was significantly higher than in patients with normal weight. This study demonstrated that masked hypertension prevalence is higher in patients with obesity than control patients. It can be suggested that predefining obesity might be helpful in early detection of masked hypertension.

    2005-07-01

    This study was conducted to obtain a detailed profile of hypothalamo-pituitary-adrenal (HPA) axis activity and reactivity and its differential relationships with body fat distribution and total fat mass in premenopausal obese women. Cortisol responses to stimulation (awakening, food intake, exercise) and suppression (0.25 mg dexamethasone), cortisol metabolism, and tissue sensitivity to glucocorticoids were studied in 53 premenopausal obese women grouped according to their waist-to hip ratio: women with abdominal body fat distribution (A-BFD; n = 31) and women with peripheral fat distribution (P-BFD; n = 22). Comparatively, A-BFD women had 1) lower awakening salivary cortisol levels; 2) increased salivary responsiveness to a standardized lunch; 3) similar pituitary sensitivity to dexamethasone but decreased sensitivity of monocytes to dexamethasone; 4) similar 24-hour urinary free cortisol but increased 24-hour urinary ratio of cortisone-to-cortisol; and 5) no difference in corticosteroid binding protein parameters. Although abdominal obesity is not very different from generalized obesity in terms of HPA function, subtle variations in HPA axis activity and reactivity are evidenced in A-BFD premenopausal obese women.

  11. Short-Term Preoperative Calorie and Protein Restriction Is Feasible in Healthy Kidney Donors and Morbidly Obese Patients Scheduled for Surgery

    Franny Jongbloed

    2016-05-01

    Full Text Available Introduction. Surgery-induced oxidative stress increases the risk of perioperative complications and delay in postoperative recovery. In mice, short-term preoperative dietary and protein restriction protect against oxidative stress. We investigated the feasibility of a calorie- and protein-restricted diet in two patient populations. Methods. In this pilot study, 30 live kidney donors and 38 morbidly obese patients awaiting surgery were randomized into three groups: a restricted diet group, who received a synthetic liquid diet with 30% fewer calories and 80% less protein for five consecutive days; a group who received a synthetic diet containing the daily energy requirements (DER; and a control group. Feasibility was assessed using self-reported discomfort, body weight changes, and metabolic parameters in blood samples. Results. Twenty patients (71% complied with the restricted and 13 (65% with the DER-diet. In total, 68% of the patients reported minor discomfort that resolved after normal eating resumed. The mean weight loss on the restricted diet was significantly greater (2.4 kg than in the control group (0 kg, p = 0.002, but not in the DER-diet (1.5 kg. The restricted diet significantly reduced levels of serum urea and plasma prealbumin (PAB and retinol binding protein (RBP. Conclusions. A short-term preoperative calorie- and protein-restricted diet is feasible in kidney donors and morbidly obese patients. Compliance is high and can be objectively measured via changes in urea, PAB, and RBP levels. These results demonstrate that this diet can be used to study the effects of dietary restriction on surgery-induced oxidative stress in a clinical setting.

    Full Text Available Background: Depression and obesity are common disorders. Obesity is also predictive of several chronic diseases like hypertension and diabetes. The aim of this study was to evaluate and compare depression frequency of obese patients with hypertension or diabetes. Methods: Weight, height and body mass index (BMI were measured. The definition of obesity was a body mass index (weight (kg/height (m2 ≥30 kg/m2. Obese patients with hypertension or diabetes were documented. All participants had a Beck Depression Inventory (BDI evaluation. Results: A total of 389 subjects were included, of whom 100, 101, 92, 96 participants were healthy, obese, obese with hypertension, obese with diabetes, respectively. Beck Depression Inventory scores of obese patients, obese patients with hypertension or diabetes were higher compared to the control group. BDI scores of obese patients with diabetes were higher compared to obese and obese with hypertension subjects.

The participants were selected according to the body mass index between 40 and 60 kg/m2. Anthropometric and biochemical data were measured during fasting. Hormones and inflammatory data were measured before and after the participants ate an isocaloric meal. Dietary records were calculated and analyzed using a nutritional assessment program. Visual analog scales were used for behaviors of the sensations of appetite and food preferences. The FTO rs9939609 variant was genotyped using real-time polymerase chain reaction.Results: Participants with the AA genotype had lower values of ghrelin and IL6 and higher values of leptin than those with TT and TA in the postprandial period. Comparing the plasma concentrations of ghrelin, insulin, IL6 and TNFα intragenotypes, it was observed that those with TT had decreased leptin and increased IL6

    Thyroid hormones are necessary for fetal brain development, and hypothyroidism in adults has been associated with mood symptoms and reduced quality of life. Nevertheless, our knowledge regarding the association and temporal relation between hypothyroidism and mental disorders is ambiguous. Our objective was to investigate, at a nationwide level, whether a diagnosis of hypothyroidism is associated with psychiatric morbidity. This is an observational cohort study. On the basis of record linkage between different Danish health registers, 2822 hypothyroid singletons each matched with 4 nonhypothyroid controls were identified and followed over a mean period of 6 years (range 1-13). Additionally, we included 385 same-sex twin pairs discordant for hypothyroidism. Diagnoses of psychiatric disorders as well as treatment with antidepressants, antipsychotics, and anxiolytics were recorded. Logistic and cox regression models were used to assess the risk of psychiatric morbidity before and after the diagnosis of hypothyroidism, respectively. Before the diagnosis of hypothyroidism, such individuals had an increased prevalence of diagnoses with psychiatric disorders (odds ratio, OR, 1.51; 95% confidence interval [CI 1.12-2.04]) and increased prevalence of treatment with antipsychotics (OR 1.49 [CI 1.29-1.73]), antidepressants (OR 1.50 [CI 1.35-1.67]), and anxiolytics (OR 1.28 [CI 1.16-1.41]). After the diagnosis of hypothyroidism, patients had a higher risk of being diagnosed with a psychiatric disorder (hazard ratio, HR, 2.40 [CI 1.81-3.18]), and an increased risk of being treated with antidepressants (HR 1.30 [CI 1.15-1.47]) and anxiolytics (HR 1.27 [CI 1.10-1.47]), but not antipsychotics (HR 1.13 [CI 0.91-1.41]). On the basis of the twin data, we could not demonstrate genetic confounding. Subjects with hypothyroidism have an increased risk of being diagnosed with a psychiatric disorder as well as being treated with antidepressants, antipsychotics, and anxiolytics both before

    The authors present the results of a prospective study regarding their 1st year experience in laparoscopic adjustable gastric banding (LABG), which included 21 patients (5 males, 16 females), with an average age of 39 (between 20-53 years). The follow up was made at one and six months postoperative. The medium weight was 138 kg (between 95-172 kg), with a medium excess of body mass of 66.89 kg (extremes between 27.75 and 104 kg). The medium BMI (body mass index) was 48.9 (extremes: 34.5-66), 8 patients being superobese (BMI > 50). The average operating time was 120 min, all operations were finished laparosopically. Postoperative complications were: total disfagia (1 case), parietal suppuration (2 cases) and partial intragastric migration of the prosthesis (1 case). There were no deceased patients. The medium excess of body mass at 6 months after surgery was 46.57 (only 13 patients evaluated in this interval). After 6 months postoperative the comorbidities were healed at half of the patients. Although we do not benefit of a long time follow up, the favorable initial results permits us to state that LABG must find its place in the efforts of struggling against obesity and its consequences.

    Obstructive sleep apnoea, a syndrome that leads to recurrent intermittent hypoxia, is associated with insulin resistance in obese individuals, but the mechanisms underlying this association remain unknown. We utilized a mouse model to examine the effects of intermittent hypoxia on insulin resistance in lean C57BL/6J mice and leptin-deficient obese (C57BL/6J-Lepob) mice. In lean mice, exposure to intermittent hypoxia for 5 days (short term) resulted in a decrease in fasting blood glucose levels (from 173 +/- 11 mg dl-1 on day 0 to 138 +/- 10 mg dl-1 on day 5, P obese mice, short-term intermittent hypoxia led to a decrease in blood glucose levels accompanied by a 607 +/- 136 % (P intermittent hypoxia was completely abolished by prior leptin infusion. Obese mice exposed to intermittent hypoxia for 12 weeks (long term) developed a time-dependent increase in fasting serum insulin levels (from 3.6 +/- 1.1 ng ml-1 at baseline to 9.8 +/- 1.8 ng ml-1 at week 12, P intermittent hypoxia is dependent on the disruption of leptin pathways.

    Abstract Human adenovirus 36 (HAdV-36), as the key pathogen, was supposed and discussed to be associated with obesity. We searched the references on the association between HAdV-36 infection and obesity with the different epidemiological methods, to explore the relationship with a larger sample size by meta-analysis and compare the differences of epidemiological methods and population subsets by the subgroup analyses. We conducted literature search on the association between HAdV-36 infections and obesity in English or Chinese published up to July 1, 2015. The primary outcome was the HAdV-36 infection rate in the obese and lean groups; the secondary outcomes were the BMI level and BMI z-score in the HAdV-36 positive and negative groups. The pooled odds ratio (OR) was calculated for the primary outcome; the standardized mean differences (SMDs) were calculated for the secondary and third outcomes. Prediction interval (PI) was graphically presented in the forest plot of the random effect meta-analyses. Metaregression analysis and subgroup analysis were performed. Finally 24 references with 10,191 study subjects were included in the meta-analysis. The obesity subjects were more likely to be infected with HAdV-36 compared to the lean controls (OR = 2.00; 95%CI: 1.46, 2.74; PI: 0.59, 6.76; P infection for obesity were 1.77 (95%CI: 1.19, 2.63; PI: 0.44, 7.03; P = 0.005) and 2.26 (95%CI: 1.67, 3.07; PI: 1.45, 3.54; P SMD of BMI was 0.28 (95% CI: 0.08, 0.47; PI: −0.53, 1.08; P = 0.006) in the HAdV-36 positive subjects with a high heterogeneity (I2 = 86.5%; P infection was higher than those without HAdV-36 infection (SMD = 0.19; 95%CI: −0.31, 0.70; PI: −2.10, 2.49), which had no significantly statistical difference (P = 0.453). HAdV-36 infection increased the risk of obesity. HAdV-36 also increased the risk of weight gain in adults, which was not observed in children. PMID:26705235

  19. An Increase in the Omega-6/Omega-3 Fatty Acid Ratio Increases the Risk for Obesity

    Simopoulos, Artemis P.

    2016-01-01

    In the past three decades, total fat and saturated fat intake as a percentage of total calories has continuously decreased in Western diets, while the intake of omega-6 fatty acid increased and the omega-3 fatty acid decreased, resulting in a large increase in the omega-6/omega-3 ratio from 1:1 during evolution to 20:1 today or even higher. This change in the composition of fatty acids parallels a significant increase in the prevalence of overweight and obesity. Experimental studies have suggested that omega-6 and omega-3 fatty acids elicit divergent effects on body fat gain through mechanisms of adipogenesis, browning of adipose tissue, lipid homeostasis, brain-gut-adipose tissue axis, and most importantly systemic inflammation. Prospective studies clearly show an increase in the risk of obesity as the level of omega-6 fatty acids and the omega-6/omega-3 ratio increase in red blood cell (RBC) membrane phospholipids, whereas high omega-3 RBC membrane phospholipids decrease the risk of obesity. Recent studies in humans show that in addition to absolute amounts of omega-6 and omega-3 fatty acid intake, the omega-6/omega-3 ratio plays an important role in increasing the development of obesity via both AA eicosanoid metabolites and hyperactivity of the cannabinoid system, which can be reversed with increased intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). A balanced omega-6/omega-3 ratio is important for health and in the prevention and management of obesity. PMID:26950145

    A best evidence topic in adult valvular surgery was written according to a structured protocol. The question addressed was 'Does concomitant tricuspid annuloplasty increase the perioperative mortality and morbidity when correcting left-sided valve disease?' A total of 561 papers were found using the reported search, of which 12 presented the best evidence to answer the clinical question. The authors, country, journal, date of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Among these 12 papers, there were nine retrospective studies, two cohort studies and one randomized controlled trial (RCT). Overall, additional tricuspid valve (TV) repair takes more time during operations, particularly with a ring annuloplasty method. The mean aortic cross-clamping times were 57-83 min without associated tricuspid repair and 62-100 min with, and cardiopulmonary bypass times without and with repair were 82-124 and 90-174 min, respectively. A study of 624 patients who had undergone isolated mitral valve (MV) surgery and MV surgery plus TV repair showed more female and atrial fibrillation patients in the tricuspid valve plasty (TVP) group, but no increase in the 30-day mortality was found. One RCT, presenting similar patient baseline characteristics, also found no difference in the hospital mortality rates between the TVP group and the non-TVP group. Another 10 studies also demonstrated no statistically significant differences in perioperative mortality. In a cohort study of 311 patients undergoing MV repair with or without tricuspid annuloplasty, postoperative complications, such as bleeding, stroke, pacemaker, haemofiltration and myocardial infarction, all showed no statistically significant differences in the two groups. One study retrospectively analysed a large number of patients undergoing either isolated left-sided valve surgery or a concomitant TV repair, and there were no statistically significant differences

  2. Muscle uncoupling protein 3 expression is unchanged by chronic ephedrine/caffeine treatment: results of a double blind, randomised clinical trial in morbidly obese females.

    Renata Bracale

    Full Text Available Ephedrine/caffeine combination (EC has been shown to induce a small-to-moderate weight loss in obese patients. Several mechanisms have been proposed, among which an increased thermogenic capacity of skeletal muscle consequent to the EC-induced up-regulation of uncoupling protein 3 (UCP3 gene expression. We did a parallel group double-blind, placebo-controlled, 4-week trial to investigate this hypothesis. Thirteen morbidly obese women (25-52 years of age, body-mass index 48.0±4.0 kg/m2, range 41.1-57.6 were randomly assigned to EC (200/20 mg, n = 6 or to placebo (n = 7 administered three times a day orally, before undergoing bariatric surgery. All individuals had an energy-deficit diet equal to about 70% of resting metabolic rate (RMR diet (mean 5769±1105 kJ/day. The RMR analysed by intention to treat and the UCP3 (long and short isoform mRNA levels in rectus abdominis were the primary outcomes. Body weight, plasma levels of adrenaline, noradrenaline, triglycerides, free fatty acids, glycerol, TSH, fT4, and fT3 were assessed, as well as fasting glucose, insulin and HOMA index, at baseline and at the end of treatments. Body weight loss was evident in both groups when compared to baseline values (overall -5.2±3.2%, p<0.0001 without significant differences between the treated groups. EC treatment increased the RMR (+9.2±6.8%, p = 0.020, differently from placebo which was linked to a reduction of RMR (-7.6±6.5%, p = 0.029. No significant differences were seen in other metabolic parameters. Notably, no changes of either UCP3 short or UCP3 long isoform mRNA levels were evident between EC and placebo group. Our study provides evidence that 4-week EC administration resulted in a pronounced thermogenic effect not related to muscle UCP3 gene expression and weight loss in morbidly obese females under controlled conditions.ClinicalTrials.gov NCT02048215.

    Full Text Available As tendências de transição nutricional ocorridas neste século direcionam para uma dieta mais ocidentalizada, a qual, aliada à diminuição progressiva da atividade física, converge para o aumento no número de casos de obesidade em todo o mundo. Isso representa aumento na morbidade e na mortalidade associadas à obesidade, já que esta é fator de risco para várias doenças como diabetes tipo II, hipertensão, doenças cardiovasculares e cálculo na vesícula biliar. A obesidade se apresenta não apenas como problema científico e de saúde pública, porém como grande indústria que envolve o desenvolvimento de fármacos, de alimentos modificados e estratégias governamentais estimulando a prática regular de atividade física e a orientação alimentar a fim de promover melhores hábitos. Assim, o conhecimento das causas e estratégias preventivas da obesidade é o objeto de estudo de pesquisadores de diferentes centros. Esse artigo tem como objetivo rever esses estudos, abordando o aumento na prevalência e incidência da obesidade, doenças relacionadas ao excesso de peso e os tratamentos para redução da gordura corporal.The trend in nutritional transition in this century leads to an occidentalized diet, which, allied to a decrease in physical activity, results in increasing of obesity all over the world. It raises the risk of morbidity and mortality, since obesity is the first step to several diseases such as Diabetes type II, hypertension, cardiovascular and gallbladder diseases. Obesity is not only a scientific and public health problem, but also an industry of pharmacos, special foods and governmental strategies to encourage people to be more active and to provide more food information in order to promote better habits. Several studies all around the world discuss the causes and treatments for obesity. In this way, this paper summarizes these researches, approaching the elements associated with higher obesity incidence and

    Full Text Available Introduction: The effects of bariatric surgery on skeletal health raise many concerns. Trabecular bone score (TBS is obtained through the analysis of lumbar spine dual X-ray absorptiometry (DXA images and allows an indirect assessment of skeletal microarchitecture (MA. The aim of our study was to evaluate the changes in bone mineral density (BMD and alterations in bone microarchitecture assessed by TBS in morbidly obese women undergoing Roux-en-Y gastric bypass (RYGB, over a three-year follow-up. Material/Methods: A prospective study of 38 morbidly obese white women, aged 46.3 ± 8.2 years, undergoing RYGB was conducted. Biochemical analyses and DXA scans with TBS evaluation were performed before and at one year and three years after surgery. Results: Patients showed normal calcium and phosphorus plasma concentrations throughout the study. However, 25-hydroxyvitamin D (25(OHD3 decreased, and 71% of patients had a vitamin D deficiency at three years. BMD at femoral neck and lumbar spine (LSBMD significantly decreased 13.53 ± 5.42% and 6.03 ± 6.79%, respectively, during the three-year follow-up; however Z-score values remained above those for women of the same age. TBS was within normal ranges at one and three years (1.431 ± 106 and 1.413 ± 85, respectively, and at the end of the study, 73.7% of patients had normal bone MA. TBS at three years correlated inversely with age (r = −0.41, p = 0.010, body fat (r = −0.465, p = 0.004 and greater body fat deposited in trunk (r = −0.48, p = 0.004, and positively with LSBMD (r = 0.433, p = 0.007, fat mass loss (r = 0.438, p = 0.007 and lean mass loss (r = 0.432, p = 0.008. In the regression analysis, TBS remained associated with body fat (β = −0.625, p = 0.031; R2 = 0.47. The fracture risk, calculated by FRAX® (University of Sheffield, Sheffield, UK, with and without adjustment by TBS, was low. Conclusion: Women undergoing RYGB in the mid-term have a preserved bone MA, assessed by TBS.

    To define whether circulating markers of oxidative stress correlate with sarcopenia in terms of glutathione balance and oxidative protein damage, and whether these biomarkers are associated with risk of cardiovascular disease (CVD). Population-based cross-sectional study. 115 out of 347 elderly subjects were classified as non-sarcopenic non-obese (NS-NO), sarcopenic non-obese (S-NO), non-sarcopenic obese (NS-O), and sarcopenic obese (S-O). Sarcopenia was defined as a relative skeletal muscle mass index (RASM) 27 for men or >38 for women. The CVD risk was estimated by the carotid intima-media thickness (IMT) and the Framingham score. Blood reduced glutathione (GSH), oxidized glutathione (GSSG), plasma malondialdehyde-(MDA) and 4-hydroxy-2,3-nonenal-(HNE) protein adducts were analyzed. Significantly greater blood GSSG/GSH ratio and plasma MDA/HNE protein adducts were observed in sarcopenic than in non-sarcopenic patients. A logistic regression model showed a close relationship between serum HNE and MDA adducts and sarcopenia (OR=1.133, 95% CI 1.057-1.215, and OR=1.592, 95% CI 1.015-1.991, respectively). Linear and logistic regression analysis evidenced strong associations between the IMT or the Framingham CVD risk category and blood GSSG/GSH or serum HNE protein adducts in the S-O group. Circulating markers of oxidative stress are increased in sarcopenia and related to CVD risk in sarcopenic obesity, suggesting that redox balance analysis would be a useful part of a multidimensional evaluation in aging. Further research is encouraged to support interventional strategies to correct redox imbalance, which might contribute to the prevention or at least limitation of sarcopenia and its co-morbidities.

    Liver biopsy, an invasive method, is the gold standard for differentiate nonalcoholic steatohepatitis (NASH) from other stages of fatty liver disease. A noninvasive test to diagnose NASH and disease severity before surgery and also for monitoring disease status after bariatric surgery (BS) will be an important medical challenge. To create a noninvasive biomarkers model for the diagnosis of NASH in overweight, obese and morbidly obese patients (MOP). Sixty patients (mean BMI= 47.81kg/m2) were admitted after exclusion of other causes of liver disease. Liver biopsies were obtained at the time of the bariatric surgery or by percutaneous liver biopsy and graded using Kleiner score. Continuous variables were compared using Wilcoxon rank sum test and for prediction of NASH we used logistic regression. Logistic regression analysis showed that BMI, ALT, AST, alkaline phosphatase (ALP), HOMA-R, hs-CRP, M30, M65, leptine and adiponectine levels remained independent predictors for NASH (p less than 0.02). Using AUC analysis, we established the following cutoff levels being indicative of NASH: BMI ė 47 kg/m2, ALT ė 32 IU/mL, AST ė 25 IU/mL, ALP ė 85 IU/mL, HOMA-IR ė 4, M65 ė 389 U/L. Adiponectine less than 13.5 mg/L. A NASH-score, calculated as the sum of these 7 parameters, at a cutoff level of 4 points, can accurately predict NASH (sensitivity of 90%, specificity of 93.94% and AUC of 0.9576). We propose a noninvasive model for NASH diagnosis in MOP that should be validated prospectively. Using this noninvasive score, NASH would be predicted without the risks of liver biopsy. Celsius.

    The plasminogen activator inhibitor type-1 (PAI-1) has been implicated in the regulation of fibrinolysis and extracellular matrix components. The single base pair guanine insertion/deletion polymorphism (4G/5G) within the promoter region of the PAI-1 gene influences PAI-1 synthesis and may modulate hepatic fibrogenesis. To evaluate the influence of PAI-1 serum levels and 4G/5G polymorphism on the risk of liver fibrosis associated to non-alcoholic fatty liver disease (NAFLD) in morbidly obese patients. Case-control study of 50 obese patients undergoing bariatric surgery and 71 non-obese subjects matched by age and sex. Anthropometric and biochemical measurements were performed, including PAI-1 serum levels. Genomic DNA was obtained to assess the presence of 4G/5G polymorphism. BMI, insulinemia, triglycerides, HOMA-IR, hypertension and diabetes were significantly higher in obese patients compared to control subjects. PAI-1 serum levels observed in obese patients were significantly lower (10.63 ± 4.82) compared to controls (14.26 ± 11.4; p 5G promoter genotypes frequencies (p = 0.12). No differences were observed in PAI-1 plasma levels among obese patients with liver fibrosis (10.64 ± 4.35) compared to patients without liver fibrosis (10.61 ± 5.2; p = 0.985). PAI-1 4G/5G promoter genotypes frequencies were similar in patients with or without liver fibrosis associated to NASH (p = 0.6). Morbidly obese patients had significantly lower PAI-1 serum levels with similar PAI-1 4G/5G genotypes frequencies compared to non-obese subjects. The frequency of 4G/5G genotypes in Chilean Hispanic healthy subjects was similar to that described in other populations. No association was found between PAI-1 serum levels or 4G/5G genotype with liver fibrosis in obese patients.

    Reports on laparoscopic sleeve gastrectomy (LSG) communicate very good short-term results on very high-risk morbid obese patients. However, mid- and long-term results are still unknown. A National Registry has been created in Spain to achieve information on the outcomes of this bariatric procedure. Data were obtained from 17 centers and collected in a database. Technical issues, preoperative comorbid conditions, hospital stay, early and late complications, and short- and mid-term weight loss were analyzed. Five hundred forty patients were included; 76% were women. Mean BMI was 48.1 +/- 10. Mean age was 44.1 +/- 11.8. Morbidity rate was 5.2% and mortality rate 0.36%. Complications presented more frequently in superobese patients (OR, 2.8 (1.18-6.65)), male (OR, 2.98 (1.26-7.0)), and patients >55 years old (OR, 2.8 (1.14-6.8)). Staple-line reinforcement was related to a lower complication rate (3.7 vs 8.8%; p = 0.039). Mean hospital stay was 4.8 +/- 8.2 days. Mean follow-up was 16.5 +/- 10.6 months (1-73). Mean percent excess BMI loss (EBL) at 3 months was 38.8 +/- 22, 55.6 +/- 8 at 6 months, 68.1 +/- 28 at 12 months, and 72.4 +/- 31 at 24 months. %EBL was superior in patients with lower initial BMI and lower age. Bougie caliber was an inverse predictive factor of %EBL at 12 and 24 months (RR, 23.3 (11.4-35.2)). DM is remitted in 81% of the patients and HTA improved in 63.2% of them. A second-stage surgery was performed in 18 patients (3.2%). LSG provides good short- and mid-term results with a low morbid-mortality rate. Better results are obtained in younger patients with lowest BMI. Staple-line reinforcement and a thinner bougie are recommended to improve outcome.

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

    Full Text Available Cushing's disease (CD is a progressive neuroendocrine disease caused by a pituitary tumor producing excessive amounts of ACTH. In most cases (80-85% the cause of the disease is a pituitary corticotroph microadenomas (located within the sella, measuring 3–10 mm, rarely multiple microadenomas and only 15% of cases are presented as corticotroph hyperplasia or pituitary macroadenoma extending beyond the sella. The macroadenomas in CD usually extend suprasellar (10%, infrasellar tumor growth is relatively rare (5%. If the clinical picture is subtle, the symptoms are caused by the development "mass effect" of the tumor as it propagates to the surrounding pituitary structures. Suprasellar growth leads to compression of the optic chiasm with narrowing of visual fields, infrasellar growth destructs the bottom of the sella turcica and may cause nasal cerebrospinal fluid leak, which is dangerous due depressurization of the cranial cavity and its communication with environmental pathogens, development of life-threatening conditions such as meningitis, meningoencephalitis, ventriculitis. Leading life-threatening complications of the CD are infectious and cardiovascular. But in the case of nasal liquorrhea with expansion of the tumor in sphenoid sinus with destruction of the bottom of the sella, there is an immediate threat to the life of the patient. This article presents an example of a patient with morbid obesity and lack of specific clinical manifestations of CD, in whom the diagnosis of disease CD was made on the results of laboratory and instrumental examination, which experienced a spontaneous nasal cerebrospinal fluid leak.

    Obesity is frequently encountered in patients with orthotopic liver transplant (OLT). The role of bariatric surgery is still unclear for this specific population. The aim of this study was to review our experience with laparoscopic sleeve gastrectomy (LSG) after OLT. We performed a retrospective case-control study of patients undergoing LSG after OLT from 2010 to 2016. OLT-LSG patients were matched by age, sex, body mass index (BMI), and year to non-OLT patients undergoing LSG. Demographics, operative variables, postoperative events, and long-term weight loss with comorbidity resolution were collected and compared between cases and controls. Of 303 patients undergoing LSG, 12 (4%) had previous OLT. They were matched to 36 non-OLT patients. No difference was found between groups in the American Society of Anesthesiologists class, mean operative time, or postoperative morbidity. The non-OLT group, however, had a significantly shorter mean hospital stay than the OLT group (1.7 vs 3.1 days; P OLT patients had significantly more excess body weight loss at 2 years (53.7 vs 45.2%; P OLT in appropriately selected patients appears to have similar outcomes to LSG in non-OLT patients.

    White adipose tissue (WAT) from visceral adiposity plays an important role in the pathogenesis of non-alcoholic steatohepatitis (NASH). Development of NASH and its progression to fibrosis is partially due to cytokines and adipokines produced by WAT. The aim of this study was to assess the association of hepatic fibrosis and NASH by evaluating the intrinsic differences in the inflammatory cytokine signaling in the visceral adipose tissue obtained from morbidly obese patients. We used targeted microarrays representing human genes involved in the inflammatory and fibrogenic reactions to profile visceral adipose samples of 15 well-matched NASH patients with and without fibrosis. Additionally, visceral adipose samples were subjected to real-time polymerase chain reaction profiling of 84 inflammations related genes. Eight genes (CCL2, CCL4, CCL18, CCR1, IL10RB, IL15RA, and LTB) were differentially expressed in NASH with fibrosis. Additionally, an overlapping but distinct list of the differentially expressed genes were found in NASH with type II diabetes (DM; IL8, BLR1, IL2RA, CD40LG, IL1RN, IL15RA, and CCL4) as compared to NASH without DM. Inflammatory cytokines are differentially expressed in the adipose tissue of NASH with fibrosis, as well in NASH with DM. These findings point at the interaction of adipose inflammatory cytokines, DM, hepatic fibrosis in NASH, and its progression to cirrhosis and end-stage liver disease.

    We assessed the relationship between insulin resistance, serum insulin-like growth factor 1 (IGF-1) levels, and common carotid intima-media thickness (CC-IMT) in morbidly obese young patients. A total of 249 patients (aged 37.9 ± 9.8 years, body mass index [BMI] 45.6 ± 8.3 kg/m(2)) were evaluated (metabolic tests, serum IGF-1 measurements, homeostasis model assessment-insulin resistance [HOMA-IR], and ultrasonographically assessed CC-IMT) in a research program for bariatric surgery candidates. After adjusting for age, gender, BMI, systolic blood pressure, uric acid, antihypertensive and lipid-lowering treatment, metabolic syndrome, and metabolic class, both HOMA-IR and IGF-1 z-score were significantly associated with CC-IMT. These results were confirmed in logistic regression analysis, in which age (β = 1.11, P = .001), gender (β = 3.19, P = .001), HOMA-IR (β = 1.221, P = .005), and IGF-1 z-score (β = 1.734, P = .009) were the only independent determinants of abnormal CC-IMT, presumably modulating the effect of the other risk factors included in the regression. Area under the receiver-operating characteristic curve for the model was 0.841 (confidence interval: 0.776-0.907; P IGF-1 z-score are significantly associated with CC-IMT, independent of other major cardiovascular risk factors. © The Author(s) 2015.

    The risk for major depression and obesity is increased in adolescents and adults with attention-deficit / hyperactivity disorder (ADHD) and adolescent ADHD predicts adult depression and obesity. Non-pharmacological interventions to treat and prevent these co-morbidities are urgently needed. Bright light therapy (BLT) improves day-night rhythm and is an emerging therapy for major depression. Exercise intervention (EI) reduces obesity and improves depressive symptoms. To date, no randomized controlled trial (RCT) has been performed to establish feasibility and efficacy of these interventions targeting the prevention of co-morbid depression and obesity in ADHD. We hypothesize that the two manualized interventions in combination with mobile health-based monitoring and reinforcement will result in less depressive symptoms and obesity compared to treatment as usual in adolescents and young adults with ADHD. This trial is a prospective, pilot phase-IIa, parallel-group RCT with three arms (two add-on treatment groups [BLT, EI] and one treatment as usual [TAU] control group). The primary outcome variable is change in the Inventory of Depressive Symptomatology total score (observer-blinded assessment) between baseline and ten weeks of intervention. This variable is analyzed with a mixed model for repeated measures approach investigating the treatment effect with respect to all three groups. A total of 330 participants with ADHD, aged 14 - obesity, ADHD symptoms, general psychopathology, health-related quality of life, neurocognitive function, chronotype, and physical fitness are explored after the end of the intervention and at the 12-week follow-up. This is the first pilot RCT on the use of BLT and EI in combination with mobile health-based monitoring and reinforcement targeting the prevention of co-morbid depression and obesity in adolescents and young adults with ADHD. If at least medium effects can be established with regard to the prevention of depressive symptoms and

    Albuminuria, a chronic kidney and/or cardiovascular disease biomarker, is currently measured as albumin-to-creatinine ratio (ACR). We hypothesize that in severely obese individuals ACR might be abnormally low in spite of relatively high levels of urinary albumin due to increased creatininuria. One-hundred-eighty-four subjects were divided into tertiles based on their BMI. Fat-free mass (FFM) and fat-mass were assessed by DEXA; 24-h creatinine and albumin excretion, ACR, lipid profile and blood pressure were measured. Twenty-four-hour creatinine highly correlated (R = 0.75) with FFM. Since both creatininuria and albuminuria increased with the BMI, being the increase in creatininuria preponderant in subjects with BMI>35, their ratio (AC-ratio) did not change significantly from that of subjects in the lower BMI tertile. ACR only correlated with the systolic blood pressure, while both albuminuria and cretininuria correlated (P = 0.01) with the absolute 10-year CHD risk. In subjects with BMI>35, 100 mg of albumin excreted with urine increased the CHD risk of 2%. Albumin-to-creatinine ratio is underestimated in severely obese individuals as a consequence of the large creatininuria, which is proportional to the increased FFM. Therefore, at least in this population 24-h albuminuria should be more reliable than ACR. Copyright © 2011 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

    Personality characteristics are assumed to underlie health behaviors and, thus, a variety of health outcomes. Our aim was to examine prospectively whether personality traits predict short- and long-term weight loss after laparoscopic adjustable gastric banding. Of patients undergoing laparoscopic adjustable gastric banding, 168 (143 women, 25 men, 18 to 58 years old, mean 37 years, preoperative BMI 45.9 +/- 5.6 kg/m(2)) completed the Dutch Personality Questionnaire on average 1.5 years before the operation. The relationship between preoperative personality and short- and long-term postoperative weight loss was determined using multilevel regression analysis. The average weight loss of patients progressively increased to 10 BMI points until 18 months after surgery and stabilized thereafter. A lower baseline BMI, being a man, and a higher educational level were associated with a lower weight loss. None of the personality variables was associated with weight outcome at short-term follow-up. Six of seven personality variables did not predict long-term weight outcome. Egoism was associated with less weight loss in the long-term postoperative period. The effect sizes of the significant predictions were small. None of the personality variables predicted short-term weight outcome, and only one variable showed a small and unexpected association with long-term weight outcome that needs confirmation. This suggests that personality assessment as intake psychological screening is of little use for the prediction of a poor or successful weight outcome after bariatric surgery.

    Although long-term results of sleeve gastrectomy (LSG) remain scarce in the literature, its popularity as a stand-alone procedure has accounted for a global increase in LSG performance. In this retrospective study, the authors present 5 to 8-year follow-up results in terms of weight loss, failure/revision rate, and comorbidity resolution from a single center. A prospectively maintained database was reviewed for patients who underwent LSG between 2007 and 2010. Data analysis on weight loss, comorbid conditions, revision surgery, and mortality was conducted. Median percentage excess BMI loss (%EBMIL) was 59.0, and 53.9 %, and median percentage total weight loss (%TWL) was 25.1, and 22.9 % at 5 and 8 years, respectively. Revision to gastric bypass due to insufficient weight loss or gastroesophageal reflux disease (GERD) was performed in 42 patients (15.2 %). Resolution of comorbid condition was achieved in 91 % of patients with obstructive sleep apnea syndrome (OSAS), 68 % of patients with type 2 diabetes (T2DM), 53 % of patients with hypertension, and 25 % of patients with dyslipedemia. Loss to follow-up rate was 45 % at 5 years, 28 % at 6 years, 23 % at 7 years, and 13 % at 8 years. This study adds to the currently available data confirming the LSG to be a safe and effective procedure at long term. Data from high-volume studies are needed to establish the definite role of the LSG in the spectrum of bariatric procedures.

    Full Text Available Introduction: Given the difficulty in accessing to the excluded stomach after gastric bypass and the increase in gastroesophageal reflux after sleeve gastrectomy, it is justified to perform a preoperative fibrogastroscopy. The influence of the fibrogastroscopy (FGS findings in the therapeutic approach is analyzed. Patients and methods: A retrospective study of preoperative FGS findings is performed, from 04/06 to 12/12. The influence of the FGS results on the surgical technique selection, in the endoscopic or medical treatment and its relation to gastric fistula is analyzed by means of multivariate regression (confounding factors: Age, body mass index, arterial hypertension, diabetes mellitus, antiplatelet therapy, surgical technique (bariatric surgery, sleeve gastrectomy. Results: Three hundred thirty one patients are included: 32.6% biopsy of gastric lesion; 27% gastritis; 18.1% hiatal hernia; 3% metaplasia; 0.6% Barrett esophagus; 2.1% esophagitis; 0.3% dysplasia; 0.3 Schatzky's ring; 1.5% incompetent cardia; 2.4% duodenitis; 0.3% gastric erosions; 0.6% gastric xanthoma; 1.8%, gastric polyp; 1.6% duodenal ulcer; 0.6% papulo-erosive gastritis; 0.6% esophageal papilloma; 0.3% submucosal tumor. Helicobacter pylori+ 30.2% (triple therapy eradication in all patients. The FGS findings led to a variation in the surgical technique or to the completion of endoscopic treatment in 22.2% of cases. The gastric lesions did not influence the development of gastric fistula. Independent prognostic factors of fistula: Sleeve gastrectomy (7.9% vs. 2.7%; p = 0.02; OR: 1.38 IC95: 1.01-1.87 and the body mass index > 50 kg/m² (6.7% vs. 2.2%; p = 0.04; OR: 3.7 IC95: 1.12-12.4. Conclusions: The diagnosis of gastroesophageal disease through preoperative FGS motivated variations in the therapeutic approach in 52% of patients, so we consider essential to include the preoperative FGS in bariatric surgery.

  20. Truncating Homozygous Mutation of Carboxypeptidase E (CPE in a Morbidly Obese Female with Type 2 Diabetes Mellitus, Intellectual Disability and Hypogonadotrophic Hypogonadism.

    Suzanne I M Alsters

    Full Text Available Carboxypeptidase E is a peptide processing enzyme, involved in cleaving numerous peptide precursors, including neuropeptides and hormones involved in appetite control and glucose metabolism. Exome sequencing of a morbidly obese female from a consanguineous family revealed homozygosity for a truncating mutation of the CPE gene (c.76_98del; p.E26RfsX68. Analysis detected no CPE expression in whole blood-derived RNA from the proband, consistent with nonsense-mediated decay. The morbid obesity, intellectual disability, abnormal glucose homeostasis and hypogonadotrophic hypogonadism seen in this individual recapitulates phenotypes in the previously described fat/fat and Cpe knockout mouse models, evidencing the importance of this peptide/hormone-processing enzyme in regulating body weight, metabolism, and brain and reproductive function in humans.

    To investigate the utility of acoustic radiation force impulse (ARFI) imaging, with the determination of shear wave velocity (SWV), to differentiate non-alcoholic fatty liver disease (NAFLD) from non-alcoholic steatohepatitis (NASH) in patients with morbid obesity before bariatric surgery. Thirty-two patients with morbid obesity were evaluated with ARFI and conventional ultrasound before bariatric surgery. The ARFI and ultrasound results were compared with liver biopsy findings, which is the reference standard. The patients were classed according to their histological findings into three groups: group A, simple steatosis; group B, inflammation; and group C, fibrosis. The median SWV was 1.57 ± 0.79 m/s. Hepatic alterations were observed in the histopathological findings for all the patients in the study (100 %), with the results of the laboratory tests proving normal. Differences in SWV were also observed between groups A, B and C: 1.34 ± 0.90 m/s, 1.55 ± 0.79 m/s and 1.86 ± 0.75 m/s (P < 0.001), respectively. The Az for differentiating NAFLD from NASH or fibrosis was 0.899 (optimal cut-off value 1.3 m/s; sensitivity 85 %; specificity 83.3 %). The ARFI technique is a useful diagnostic tool for differentiating NAFLD from NASH in asymptomatic patients with morbid obesity. (orig.)

    This study aims to determine preferences of a nationally representative sample of obstetrician/gynecologists (OB/GYNs) regarding cesarean delivery (CD) incision practices for women with morbid obesity (body mass index ≥ 40 kg/m(2)). We conducted an online survey using the American College of Obstetricians and Gynecologists database. We compared physician demographics, practice characteristics, and CD incision type preference. After exclusion of ineligible participants, 247 OB/GYNs completed the survey (42% response rate). In nonemergency CD of morbidly obese women, 84% of physicians preferred a Pfannenstiel skin incision (67% preferring taping the pannus; 17% without taping the pannus). In emergency CD, 66% preferred a Pfannenstiel incision (46% without taping the pannus; 20% with taping the pannus) and 20% a vertical incision. For both emergency and nonemergency CD, there was no difference in incision type preferences by provider years in practice, practice scope, or number of CD performed each year. Given the preference of a Pfannenstiel incision with taping the pannus during CD of morbidly obese women, further investigation is needed to assess the risks and benefits of this incision and the practice of elevating the pannus.

  5. Long-Term Follow-Up Is Essential to Assess Outcome of Gastric Banding in Morbidly Obese Adolescents: A Retrospective Analysis

    Givan F. Paulus

    2016-10-01

    Full Text Available Background: Adolescent obesity is rapidly becoming more prevalent and is associated with chronic health conditions and psychosocial morbidity. Lifestyle intervention is often ineffective in morbidly obese adolescents, and bariatric surgery is gradually becoming an accepted treatment. However, little is known about long-term results. Methods: Hospital charts of patients who had undergone gastric banding more than 5 years ago at an age of 18 years or younger, were retrospectively analyzed. Weight loss, complications, reoperations, and comorbidity reduction were assessed as well as health status, food behavior, and personality. Results: BMI loss in 10 adolescents was 10.7 kg/m2 (-0.9 to 12.9 kg/m2 after a median follow-up of 64 months (52-84 months; the major part of weight loss occurred after the first year. In 4 patients the gastric band was removed after 3.5-5.5 years. Two out of 3 patients effectively lost weight after conversion to a bypass type procedure. One patient is maintaining a stable healthy weight after band removal. Conclusions: Laparoscopic adjustable gastric banding in morbidly obese adolescents had a failure rate of 40%, but was a successful therapy in the other 60% without major adverse events. Follow-up longer than 36 months was crucial for optimal evaluation of weight loss and reoperation rate.

    Asians are at increased risk of morbidity at a lower body mass index (BMI) than European Whites, particularly relating to metabolic risk. UK maternal obesity guidelines use general population BMI criteria to define obesity, which do not represent the risk of morbidity among Asian populations. This study compares incidence of first trimester obesity using Asian-specific and general population BMI criteria. A retrospective epidemiological study of 502,474 births between 1995 and 2007, from 34 maternity units across England. Data analyses included a comparison of trends over time between ethnic groups using Asian-specific and general population BMI criteria. Logistic regression estimated odds ratios for first trimester obesity among ethnic groups following adjustment for population demographics. Black and South Asian women have a higher incidence of first trimester obesity compared with White women. This is most pronounced for Pakistani women following adjustment for population structure (OR 2.19, 95% C.I. 2.08, 2.31). There is a twofold increase in the proportion of South Asian women classified as obese when using the Asian-specific BMI criteria rather than general population BMI criteria. The incidence of obesity among Black women is increasing at the most rapid rate over time (p=0.01). The twofold increase in maternal obesity among South Asians when using Asian-specific BMI criteria highlights inequalities among pregnant women. A large proportion of South Asian women are potentially being wrongly assigned to low risk care using current UK guidelines to classify obesity and determine care requirements. Further research is required to identify if there is any improvement in pregnancy outcomes if Asian-specific BMI criteria are utilised in the clinical management of maternal obesity to ensure the best quality of care is provided for women irrespective of ethnicity.

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

  10. TEMPOL increases NAD+ and improves redox imbalance in obese mice

    2016-08-01

    Full Text Available Continuous energy conversion is controlled by reduction–oxidation (redox processes. NAD+ and NADH represent an important redox couple in energy metabolism. 4-Hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPOL is a redox-cycling nitroxide that promotes the scavenging of several reactive oxygen species (ROS and is reduced to hydroxylamine by NADH. TEMPOL is also involved in NAD+ production in the ascorbic acid–glutathione redox cycle. We utilized the chemical properties of TEMPOL to investigate the effects of antioxidants and NAD+/NADH modulators on the metabolic imbalance in obese mice. Increases in the NAD+/NADH ratio by TEMPOL ameliorated the metabolic imbalance when combined with a dietary intervention, changing from a high-fat diet to a normal diet. Plasma levels of the superoxide marker dihydroethidium were higher in mice receiving the dietary intervention compared with a control diet, but were normalized with TEMPOL consumption. These findings provide novel insights into redox regulation in obesity.

    The aim of this study is to evaluate the effect of massive weight loss on the seminal parameters at 6 months from bariatric surgery. Two-armed prospective study performed in 31 morbidly obese men, undergoing laparoscopic roux-en-Y-gastric bypass (n = 23) or non-operated (n = 8), assessing sex hormones, conventional (sperm motility, morphology, number, semen volume), and non-conventional (DNA fragmentation and seminal interleukin-8), semen parameters, at baseline and after 6 months from surgery or patients' recruitment. In operated patients only, a statistically significant improvement in the sex hormones was confirmed. Similarly, a positive trend in the progressive/total sperm motility and number was observed, though only the increase in semen volume and viability was statistically significant (Δ = 0.6 ml and 10%, P semen volume (r = 0.618, P = 0.015). The massive weight loss obtained with bariatric surgery was associated with an improvement in some semen parameters. The correlations found between weight loss and semen parameter variations after surgery suggest that these might occur early downstream of the testis and more slowly than the changes in the sex hormones.

  12. The Effect of Laparoscopic Sleeve Gastrectomy with Concomitant Hiatal Hernia Repair on Gastroesophageal Reflux Disease in the Morbidly Obese.

    Samakar, Kamran; McKenzie, Travis J; Tavakkoli, Ali; Vernon, Ashley H; Robinson, Malcolm K; Shikora, Scott A

    2016-01-01

    The effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) is controversial. Although concomitant hiatal hernia repair (HHR) at the time of LSG is common and advocated by many, there are few data on the outcomes of GERD symptoms in these patients. The aim of this study was to evaluate the effect of concomitant HHR on GERD symptoms in morbidly obese patients undergoing LSG. A single institution, multi-surgeon, prospectively maintained database was examined to identify patients who underwent LSG and concomitant HHR from December 2010 to October 2013. Patient characteristics, operative details, and postoperative outcomes were analyzed. Standardized patient questionnaires administered both pre- and postoperatively were utilized. Primary endpoints included subjective reflux symptoms and the need for antisecretory therapy. Weight loss was considered a secondary endpoint. Fifty-eight patients were identified meeting inclusion criteria (LSG + HHR), with a mean follow-up of 97.5 weeks (range 44-172 weeks). The mean age of the cohort was 49.5 ± 11.2 years, with 74.1 % being female. Mean preoperative BMI was 44.2 ± 6.6 kg/m(2). Preoperative upper gastrointestinal contrast series was performed in all patients and demonstrated a hiatal hernia in 34.5 % of patients and reflux in 15.5 % of patients. Preoperatively, 44.8 % (n = 26) of patients reported subjective symptoms of reflux and/or required daily antisecretory therapy [Corrected]. After LSG + HHR, 34.6 % of symptomatic patients had resolution of their symptoms off therapy while the rest remained symptomatic and required daily antisecretory therapy; 84.4 % of patients that were asymptomatic preoperatively remained asymptomatic after surgery. New onset reflux symptoms requiring daily antisecretory therapy was seen in 15.6 % of patients who were previously asymptomatic. Post surgical weight loss did not correlate with the presence or resolution of reflux symptoms. Based

    Little is known about the psychological prerequisites for weight loss maintenance after bariatric surgery. A first step in investigating whether existing knowledge of conservative weight loss treatment is applicable for lifestyle interventions postoperatively is to compare specific psychological characteristics at baseline. The aim of this study was to compare patients scheduled for bariatric surgery with patients receiving conservative treatment for morbid obesity on measures of behavioral and psychosocial characteristics considered predictors of their adoption of and adherence to long-term lifestyle recommendations. Baseline clinical and questionnaire data from the prospective "Oslo Bariatric Surgery Study" were used to examine potential differences between bariatric surgery patients (n = 301) and patients receiving conservative weight loss treatment (n = 261). The surgical group was characterized by their younger age (43.8 vs. 46.2 years, p changing their eating behaviors (OR = 1.80, 95 % CI 1.06, 1.93). The surgical patients were also less ready to change physical activity levels (OR = 0.59, 95 % CI 0.48, 0.73), had tried more types of unhealthy weight loss methods in the past (OR = 1.16, 95 % CI 1.01, 1.33), drank soda more frequently (OR = 1.24, 95 % CI 1.02, 1.50), had fewer binge eating episodes (OR = 0.38, 95 % CI 0.20, 0.71), and had more depressive symptoms (OR = 1.19, 95 % CI 1.09, 1.29). Patients opting for bariatric surgery had more positive expectations of the treatment outcomes and stronger beliefs in their ability to achieve these outcomes. Those starting conservative treatment had stronger beliefs in readiness to change physical activity levels. Future studies should explore the effect of interventions for bariatric surgery patients, promoting postoperative physical activity and stress realistic outcome expectations. The potential effects of incorporating this knowledge in intervention strategies remain to be

    Embolization of the left gastric artery (LGA) reduces circulating levels of ghrelin, but might prevent from further obesity surgery, particularly sleeve gastrectomy (SG), since the gastroesophageal junction (GEJ), depending on LGA, would be devascularized. Our aim was to evaluate, in an experimental animal study, an endovascular approach targeting arteries of the gastroepiploic arcade aiming to modulate ghrelin levels and to generate an increased vascular supply of the GEJ to reduce the risks of staple-line leaks after SG. Seven pigs underwent embolization of both left and right gastroepiploic arteries (LGEA and RGEA) using 500-700-μ microspheres (embolization of arterial gastric supply in obesity (EMBARGO)-alpha). A SG was performed in six pigs 3 weeks after EMBARGO-alpha and on eight controls. Capillary lactates were measured at the cardia and pylorus. Five pigs underwent coiling of RGEA and embolization of LGEA using both coils and 100-300-μ microspheres (EMBARGO-beta). Ghrelin levels were assessed before and once per week after both EMBARGOs. Control celiac trunk angiography was performed at 3 weeks (alpha) and 4 weeks (beta). No significant ghrelin reduction was obtained with EMBARGO-alpha at 3 weeks when compared to baseline. Significant ghrelin reduction was found 3 weeks (p = 0.0363) and 4 weeks (p = 0.025) after EMBARGO-beta. Post-EMBARGO-alpha animals presented a significantly lower increase in cardia lactates when compared to controls after SG. Control angiography showed a significantly increased fundic vascular network in 5/6 animals after EMBARGO-alpha and in 5/5 after EMBARGO-beta. EMBARGO is effective to decrease ghrelin production and can enhance the vascular supply of the GEJ, preparing the vascular background for a SG.

    Obesity is a growing public health concern and is more prevalent among low-income and minority populations. Food insecurity may increase the odds of obesity in children. We investigated the association between food insecurity and obesity among low-income, Hispanic, mother-child dyads (n = 74). The United States Department of Agriculture 18-item Household Food Security Survey was used to determine food security status. The majority of households were food insecure (74 %) and one-third (30 %) of children were obese. Food insecurity increased the odds of childhood obesity (OR 10.2; 95 % CI 1.2, 85.5) with stronger associations found within households where mothers were also overweight/obese compared to normal weight (p-for interaction food insecurity and childhood obesity were high among this low-income Hispanic sample. Future studies should elucidate the mechanisms through which food insecurity impacts childhood obesity.

    2016-11-01

    Obesity is frequently associated with complications after total hip arthroplasty (THA) and is often concomitant with malnutrition. The purpose of this study was to investigate the independent morbidity risk of malnutrition relative to obesity. The National Surgical Quality Improvement Program from 2005 to 2013 was queried for elective primary THA cases. Malnutrition was defined as albumin malnutrition with 30-day outcomes. A total of 40,653 THA cases were identified, of which 20,210 (49.7%) had preoperative albumin measurements. Propensity score adjustment successfully reduced potential selection bias, with P > .05 for differences between those with and without albumin data. Malnutrition incidence increased from 2.8% in obese I to 5.7% in obese III patients. With multivariable propensity-adjusted logistic regression, malnutrition was a more robust predictor than any obesity class for any postoperative complication(s) (odds ratio [OR] 1.61, 95% confidence interval [CI] 1.25-2.08), major complications (OR 1.63, 95% CI 1.21-2.19), respiratory complications (OR 2.35, 95% CI 1.27-4.37), blood transfusions (OR 1.71, 95% CI 1.44-2.03), and extended length of stay (OR 1.35, 95% CI 1.14-1.59). Malnutrition incidence increased significantly from obese I to obese III patients and was a stronger and more consistent predictor than obesity of complications after THA.

    2014-07-01

    The aim of this study is to evaluate the results of routine and selective postoperative upper gastrointestinal series (UGIS) after Roux-en-Y gastric bypass (RYGB) for morbid obesity in different published series to assessing its utility and cost-effectiveness. A search in PubMed's MEDLINE was performed for English-spoken articles published from January 2002 to December 2012. Keywords used were upper GI series, RYGB, and obesity. Only cases of anastomotic leaks were considered. A total of 22 studies have been evaluated, 15 recommended a selective use of postoperative UGIS. No differences in leakage detection or in clinical benefit between routine and selective approaches were found. Tachycardia and respiratory distress represent the best criteria to perform UGIS for early diagnosis of anastomotic leak after a RYGB.

    Most pharmacokinetic (PK) models used for propofol administration are based on studies in normal-weight patients. Extrapolation of these models for morbidly obese patients is controversial. Using 2 PK models and a target-controlled infusion system, we determined the predicted propofol effect-site concentration (Ce) needed for induction of anesthesia in morbidly obese subjects using total body weight. Sixty-six morbidly obese subjects from 18 to 50 years of age were randomized to receive propofol to reach and maintain a predetermined propofol Ce, based on the PK models of either Marsh or Schnider. All patients were monitored with a Bispectral Index electroencephalographic monitor. Fentanyl 3 μg/kg total body weight was administered before starting the propofol infusion. After loss of consciousness, vecuronium was administered to facilitate endotracheal intubation. Groups of 6 patients each received propofol at a different, predetermined target propofol Ce. An "effective Ce" (ECe) was defined as the propofol Ce that provided adequate hypnosis (Bispectral Index <60) during the complete induction period (45 seconds after reaching the predetermined target Ce until 5 minutes after tracheal intubation). Heart rate and arterial blood pressure were measured every 1 minute throughout the study period. Probit regression analysis was performed to calculate the effective propofol Ce values to induce hypnosis in 50% (ECe(50)) and 95% (ECe(95)) of patients with 95% confidence intervals (CIs). Patient characteristics were similar between models and across the propofol target concentration groups. The ECe(50) of propofol was 3.4 μg/mL (95% CI: 2.9, 3.7 μg/mL) with the Marsh model and 4.5 μg/mL (95% CI: 4.1, 4.8 μg/mL) with the Schnider model (P < 0.001). The ECe(95) values were 4.2 μg/mL (95% CI: 3.8, 6.2 μg/mL) and 5.5 μg/mL (95% CI: 5.0, 7.2 μg/mL) with Marsh and Schnider models, respectively. At the ECe(95), hemodynamic effects were similar with the 2 PK models

    2010-01-01

    In a previous article, we showed that the pharmacokinetic set of remifentanil used for target-controlled infusion (TCI) might be biased in obese patients because it incorporates flawed equations for the calculation of lean body mass (LBM), which is a covariate of several pharmacokinetic parameters in this set. The objectives of this study were to determine the predictive performance of the original pharmacokinetic set, which incorporates the James equation for LBM calculation, and to determine the predictive performance of the pharmacokinetic set when a new method to calculate LBM was used (the Janmahasatian equations). This was an observational study with intraoperative observations and no follow-up. Fifteen morbidly obese inpatients scheduled for bariatric surgery were included in the study. The intervention included manually controlled continuous infusion of remifentanil during the surgery and analysis of arterial blood samples to determine the arterial remifentanil concentration, to be compared with concentrations predicted by either the unadjusted or the adjusted pharmacokinetic set. The statistical analysis included parametric and non-parametric tests on continuous variables and determination of the median performance error (MDPE), median absolute performance error (MDAPE), divergence and wobble. The median values (interquartile ranges) of the MDPE, MDAPE, divergence and wobble for the James equations during maintenance were -53.4% (-58.7% to -49.2%), 53.4% (49.0-58.7%), 3.3% (2.9-4.7%) and 1.4% h(-1) (1.1-2.5% h(-1)), respectively. The respective values for the Janmahasatian equations were -18.9% (-24.2% to -10.4%), 20.5% (13.3-24.8%), 2.6% (-0.7% to 4.5%) and 1.9% h(-1) (1.4-3.0% h(-1)). The performance (in terms of the MDPE and MDAPE) of the corrected pharmacokinetic set was better than that of the uncorrected one. The predictive performance of the original pharmacokinetic set is not clinically acceptable. Use of a corrected LBM value in morbidly obese

    Fibroblast growth factor-21 (FGF21) and omentin-1 have been recognized as potent antidiabetic agents with potential hepatoprotective activity. The aim of this study was to evaluate hepatic FGF21 and omentin-1 mRNA expression as well as their serum levels as predictive markers of liver injury and insulin resistance in morbidly obese women with non-alcoholic fatty liver disease (NAFLD). This study included 56 severely obese women who underwent intraoperative wedge liver biopsy during the bariatric surgery. Hepatic FGF21 and omentin-1 mRNA were assessed by quantitative real-time PCR, while their serum concentrations were measured with commercially available enzyme-linked immunosorbent assays. The FGF21 serum level was significantly higher in patients with a greater extent of steatosis (grade 2 and 3) compared to those without or with mild steatosis (grade 0 and 1) (P = 0.049). Receiver Operating Characteristic analysis, however, showed poor discriminant power for the FGF21 serum levels in differentiating between more and less extensive steatosis with an AUC = 0.666. There was a tendency towards higher levels of hepatic FGF21 mRNA in patients with lobular inflammation and fibrosis and towards lower levels in the case of hepatocyte ballooning and steatosis. There was a positive mutual correlation between hepatic FGF21 and omentin-1 mRNA levels (r = 0.78; P hepatic omentin-1 mRNA levels showed a tendency to be lower in patients with advanced steatosis and hepatocyte ballooning. In conclusion, our study, which focused on hepatic FGF21 and omentin-1 mRNA expression, confirmed marked expression of both molecules in the liver of morbidly obese patients with NAFLD. More extensive steatosis was associated with evident changes in the serum FGF21 concentration in morbidly obese women with NAFLD, but the difference did not reach statistical significance. The vast amount of fat, both visceral and subcutaneous, in severely obese patients may be the additional source and influence

    Quantify the health impacts on morbidity of reduced car trips and increased public transport and cycling trips. A health impact assessment study of morbidity outcomes related to replacing car trips in Barcelona metropolitan (3,231,458 inhabitants). Through 8 different transport scenarios, the number of cases of disease or injuries related to physical activity, particulate matter air pollution public transport and cycling trips resulted in annual reductions of 127 cases of diabetes, 44 of cardiovascular diseases, 30 of dementia, 16 minor injuries, 0.14 major injuries, 11 of breast cancer and 3 of colon-cancer, amounting to a total reduction of 302 Disability Adjusted Life Years per year in travelers. The reduction in PM2.5 exposure in the general population resulted in annual reductions of 7 cases of low birth weight, 6 of preterm birth, 1 of cardiovascular disease and 1 of lower respiratory tract infection. Transport policies to reduce car trips could produce important health benefits in terms of reduced morbidity, particularly for those who take up active transportation. © 2013.

  4. The Medical Risks of Obesity

    2009-01-01

    Obesity is at epidemic proportions in the United States and in other developed and developing countries. The prevalence of obesity is increasing not only in adults, but especially among children and adolescents. In the United States in 2003 to 2004, 17.1% of children and adolescents were overweight, and 32.2% of adults were obese. Obesity is a significant risk factor for and contributor to increased morbidity and mortality, most importantly from cardiovascular disease (CVD) and diabetes, but ...

    In patients undergoing elective partial pancreatectomy, our aim was to evaluate the effect of metabolic syndrome (MS) on postoperative mortality, morbidity, and utilization of hospital resources. Our hypothesis was that MS is associated with worse surgical outcomes after pancreatectomy. Fifteen thousand eight hundred thirty-one patients undergoing elective pancreatectomy from 2005 to 2012 were identified in the Participant User File of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Univariable and multivariable analyses were performed examining the association of MS (defined as body mass index ≥30 kg/m(2), hypertension requiring medications, and diabetes requiring medications and/or insulin) and risk of 30-day mortality, morbidity, and utilization of hospital resources (risk of blood transfusion in the first 72 h after pancreatectomy and prolonged hospital stay, defined as ≥13 days, which was the 75th percentile of this cohort). Multivariable logistic regression models controlled for age, sex, race, pancreatectomy type (distal versus proximal), smoking status, alcohol consumption, functional status, dyspnea, cardiovascular disease, hematocrit, INR, serum albumin, bilirubin, and creatinine. Stratified analyses were conducted by type of pancreatectomy and indication for pancreatectomy (benign versus malignant). On univariate analysis, 1070 (6.8%) patients had MS. MS was associated with increased postoperative morbidity, major morbidity, surgical site infection, septic shock, cardiac event, respiratory failure, pulmonary embolism, blood transfusion, and prolonged duration of hospital stay (P pancreatectomy (P = 0.465). When stratified by distal versus proximal pancreatectomy and benign versus malignant disease, the effect of MS on outcomes appears to be modified by type of pancreatectomy and indication with poorer outcomes observed for distal pancreatectomies and benign indications for resection. MS is an under

    Background A sedentary lifestyle is an independent risk factor for cardiovascular disease and exercise has been shown to ameliorate this risk. Inactivity is associated with a loss of muscle mass, which is also reversed with isometric exercise training. The relationship between muscle mass and vascular function is poorly defined. The aims of the current study were to determine whether increasing muscle mass by genetic deletion of myostatin, a negative regulator of muscle growth, can influence vascular function in mesenteric arteries from obese db/db mice. Methods and Results Myostatin expression was elevated in skeletal muscle of obese mice and associated with reduced muscle mass (30% to 50%). Myostatin deletion increased muscle mass in lean (40% to 60%) and obese (80% to 115%) mice through increased muscle fiber size (PMyostatin deletion decreased adipose tissue in lean mice, but not obese mice. Markers of insulin resistance and glucose tolerance were improved in obese myostatin knockout mice. Obese mice demonstrated an impaired endothelial vasodilation, compared to lean mice. This impairment was improved by superoxide dismutase mimic Tempol. Deletion of myostatin improved endothelial vasodilation in mesenteric arteries in obese, but not in lean, mice. This improvement was blunted by nitric oxide (NO) synthase inhibitor l‐NG‐nitroarginine methyl ester (l‐NAME). Prostacyclin (PGI2)‐ and endothelium‐derived hyperpolarizing factor (EDHF)‐mediated vasodilation were preserved in obese mice and unaffected by myostatin deletion. Reactive oxygen species) was elevated in the mesenteric endothelium of obese mice and down‐regulated by deletion of myostatin in obese mice. Impaired vasodilation in obese mice was improved by NADPH oxidase inhibitor (GKT136901). Treatment with sepiapterin, which increases levels of tetrahydrobiopterin, improved vasodilation in obese mice, an improvement blocked by l‐NAME. Conclusions Increasing muscle mass by genetic deletion of

    This study evaluated the impact of feet callosities, arm posture, and use of electrolyte wipes on body composition measurements by bioelectrical impedance analysis (BIA) in morbidly obese adults. 36 morbidly obese patients (13 males, aged 28-70 years, BMI 41.6 ± 4.3 kg/m2) with moderate/severe feet callosities participated in this study. Body composition (percent body fat (%BF)) was measured while fasting using multi-frequency BIA (InBody 720®), before and after removal of callosities, with and without InBody® electrolyte wipes and custom-built auxiliary pads (to assess arm posture impact). Results from BIA were compared to air displacement plethysmography (ADP, BodPod®). Median %BF was significantly higher with auxiliary pads than without (50.1 (interquartile range 8.2) vs. 49.3 (interquartile range 9.1); p interquartile range 9.1) vs. 50.0 (interquartile range 7.9); NS) or use of wipes (49.6 (interquartile range 8.5) vs. 49.3 (interquartile range 9.1); NS). No differences in %BF were found between BIA and ADP (49.1 (IQR: 8.9) vs. 49.3 (IQR: 9.1); NS). Arm posture has a significant impact on %BF assessed by BIA, contrary to the presence of feet callosities and use of electrolyte wipes. Arm posture standardization during BIA for body composition assessment is, therefore, recommended. © 2015 S. Karger GmbH, Freiburg.

    2013-12-01

    To prospectively characterize acute hyperammonemic episodes in patients with urea cycle disorders (UCDs) in terms of precipitating factors, treatments, and use of medical resources. This was a prospective, longitudinal observational study of hyperammonemic episodes in patients with UCD enrolled in the National Institutes of Health-sponsored Urea Cycle Disorders Consortium Longitudinal Study. An acute hyperammonemic event was defined as plasma ammonia level >100 μmol/L. Physician-reported data regarding the precipitating event and laboratory and clinical variables were recorded in a central database. In our study population, 128 patients with UCD experienced a total of 413 hyperammonemia events. Most patients experienced between 1 and 3 (65%) or between 4 and 6 (23%) hyperammonemia events since study inception, averaging fewer than 1 event/year. The most common identifiable precipitant was infection (33%), 24% of which were upper/lower respiratory tract infections. Indicators of increased morbidity were seen with infection, including increased hospitalization rates (P = .02), longer hospital stays (+2.0 days; P = .003), and increased use of intravenous ammonia scavengers (+45%-52%; P = .003-.03). Infection is the most common precipitant of acute hyperammonemia in patients with UCD and is associated with indicators of increased morbidity (ie, hospitalization rate, length of stay, and use of intravenous ammonia scavengers). These findings suggest that the catabolic and immune effects of infection may be a target for clinical intervention in inborn errors of metabolism. Published by Mosby, Inc.

  12. Management of gastric leaks after laparoscopic sleeve gastrectomy for morbid obesity: A tertiary care experience and design of a management algorithm

    2016-01-01

    Full Text Available Background: Laparoscopic sleeve gastrectomy (LSG is the most commonly performed 'standalone' bariatric procedure in India. Staple line gastric leaks occur infrequently but cause significant and prolonged morbidity. The aim of this retrospective study was to analyse the management of patients with a gastric leak after LSG for morbid obesity at our institution. Patients and Methods: From February 2008 to 2014, 650 patients with different degrees of morbid obesity underwent LSG. Among these, all those diagnosed with a gastric leak were included in the study. Patients referred to our institution with gastric leak after LSG were also included. The time of presentation, site of leak, investigations performed, treatment given and time of closure of all leaks were analysed. Results: Among the 650 patients who underwent LSG, 3 (0.46% developed a gastric leak. Two patients were referred after LSG was performed at another institution. The mean age was 45.60 ± 15.43 years. Mean body mass index (BMI was 44.79 ± 5.35. Gastric leak was diagnosed 24 h to 7 months after surgery. One was early, two were intermediate and two were late leaks. Two were type I and three were type II gastric leaks. Endoscopic oesophageal stenting was used variably before or after re-surgery. Re-surgery was performed in all and included stapled fistula excision (re-sleeve, suture repair only or with conversion to roux-en-Y gastric bypass or fistula jujenostomy. There was no mortality. Conclusion: Leakage closure time may be shorter with intervention than expectant management. Sequence and choice of endoscopic oesophageal stenting and/or surgical re-intervention should be individualized according to clinical presentation.

    2015-01-01

    Objective: The aim of this study was to evaluate the concentrations of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and the degree of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with morbid obesity exposed to a three-week low-calorie diet and balneotherapy. Methods: The study included 33 patients (25 females and 8 males; mean age 46 years) with body mass index (BMI) values of >40 kg/m2. Evaluations of CRP, IL-6, TNF-α, lipid profile, HOMA-IR, and fasting glucose were carried out before (baseline data) and three weeks after the treatment. The control group consisted of 20 healthy volunteers (15 females and 5 males) with a mean age of 39 years and BMI values of ≤24.9 kg/m2. Results: In the blood of patients with morbid obesity we found significantly elevated levels of CRP, TNF-α, triglycerides, HOMA-IR and fasting glucose, but a decreased level of high density lipoprotein (HDL)-cholesterol, compared with the healthy individuals. The treatment resulted in about a 9.4% reduction in body weight from 122.5 to 111.0 kg and a significant decrease in the concentration of CRP, but no change in TNF-α or IL-6. HOMA-IR was significantly reduced. Conclusions: The decrease in CRP level without changes in TNF-α or IL-6 concentrations after the low-calorie diet and balneological treatment, suggests that an essential amount of adipose tissue must be removed before proper adipocyte function is restored. The decrease in HOMA-IR indicates an improvement in insulin sensitivity, which is beneficial in obese patients. PMID:25990058

  15. Low Dopamine D2 Receptor Increases Vulnerability to Obesity Via Reduced Physical Activity, Not Increased Appetitive Motivation.

    Beeler, Jeff A; Faust, Rudolf P; Turkson, Susie; Ye, Honggang; Zhuang, Xiaoxi

    2016-06-01

    The dopamine D2 receptor (D2R) has received much attention in obesity studies. Data indicate that D2R is reduced in obesity and that the TaqA1 D2R variant may be more prevalent among obese persons. It is often suggested that reduced D2R generates a reward deficiency and altered appetitive motivation that induces compulsive eating and contributes to obesity. Although dopamine is known to regulate physical activity, it is often neglected in these studies, leaving open the question of whether reduced D2R contributes to obesity through alterations in energy expenditure and activity. We generated a D2R knockdown (KD) mouse line and assessed both energy expenditure and appetitive motivation under conditions of diet-induced obesity. The KD mice did not gain more weight or show increased appetitive motivation compared with wild-type mice in a standard environment; however, in an enriched environment with voluntary exercise opportunities, KD mice exhibited dramatically lower activity and became more obese than wild-type mice, obtaining no protective benefit from exercise opportunities. These data suggest the primary contribution of altered D2R signaling to obesity lies in altered energy expenditure rather than the induction of compulsive overeating.

  17. Genomic and metabolic disposition of non-obese type 2 diabetic rats to increased myocardial fatty acid metabolism.

    Sriram Devanathan

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

    Full Text Available Sustainable development as general acceptance is that form of ensuring the bio-socio-economic needs of the present generation without affecting the existence and development opportunities for the generations to come. Secondary, the concept refers to the protection of the environment that is at present greatly affected by externalities of the socio-economic activity of previous and present generations. As it is shown in this paper the negative effects of the environmental pollution records higher and higher values in a short period of time of which we analyze their impact on population health, focusing on the situation of Romania. I started the analysis from the assumptions that the health of an organism is a normal physical and physiological state, being the opposite of the concept disease. The most common diseases are: hereditary, infectious, internal, infantile, autoimmune, allergic, socio-professional, tumorous, degenerative diseases etc. Of these infant, allergic, tumorous and autoimmune diseases are mainly generated by environmental pollution. Extremely special, regarding the incidence of harmful environmental factors, are the socio-professional diseases or of civilization that are represented by those diseases that are more common in industrialized countries than in the so called third world. In respect to air pollution-generated illnesses with products resulting from burning fossil fuels are highlighted respiratory diseases, immunological diseases, benign and malignant neoplasm of the airways and also dermatitis. Most activities follow sooner or later to increase welfare. Economic growth, environmental protection as well as fulfilling social needs of individuals are only a few elements that lead to the increase of population welfare. If we accept the above mentioned things, then it means that promoting the realisation of sustainable development based on clean and renewable resources and the rationally using the conventional ones is an

    Laparoscopic sleeve gastrectomy for treatment of morbid obesity has increased substantially despite the lack of long-term results compared with laparoscopic Roux-en-Y gastric bypass. To determine whether laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are equivalent for weight loss at 5 years in patients with morbid obesity. The Sleeve vs Bypass (SLEEVEPASS) multicenter, multisurgeon, open-label, randomized clinical equivalence trial was conducted from March 2008 until June 2010 in Finland. The trial enrolled 240 morbidly obese patients aged 18 to 60 years, who were randomly assigned to sleeve gastrectomy or gastric bypass with a 5-year follow-up period (last follow-up, October 14, 2015). Laparoscopic sleeve gastrectomy (n = 121) or laparoscopic Roux-en-Y gastric bypass (n = 119). The primary end point was weight loss evaluated by percentage excess weight loss. Prespecified equivalence margins for the clinical significance of weight loss differences between gastric bypass and sleeve gastrectomy were -9% to +9% excess weight loss. Secondary end points included resolution of comorbidities, improvement of quality of life (QOL), all adverse events (overall morbidity), and mortality. Among 240 patients randomized (mean age, 48 [SD, 9] years; mean baseline body mass index, 45.9, [SD, 6.0]; 69.6% women), 80.4% completed the 5-year follow-up. At baseline, 42.1% had type 2 diabetes, 34.6% dyslipidemia, and 70.8% hypertension. The estimated mean percentage excess weight loss at 5 years was 49% (95% CI, 45%-52%) after sleeve gastrectomy and 57% (95% CI, 53%-61%) after gastric bypass (difference, 8.2 percentage units [95% CI, 3.2%-13.2%], higher in the gastric bypass group) and did not meet criteria for equivalence. Complete or partial remission of type 2 diabetes was seen in 37% (n = 15/41) after sleeve gastrectomy and in 45% (n = 18/40) after gastric bypass (P > .99). Medication for dyslipidemia was discontinued in 47% (n

    The treatment of rectal cancer via laparoscopy is controversial due to its technical complexity. Several randomized prospective studies have demonstrated clear advantages for the patient with similar oncological results to those of open surgery, although during the learning of this surgical technique there may be an increase in complications and a worse prognosis. Our aim is to analyze how the learning curve for rectal cancer via laparoscopy influences intra- and postoperative results and oncological markers. A retrospective review was conducted of the first 120 patients undergoing laparoscopic surgery for rectal neoplasia. The operations were performed by the same surgical team with a wide experience in the treatment of open colorectal cancer and qualified to perform advanced laparoscopic surgery. We analyzed sex, ASA, tumour location, neoadjuvant treatment, surgical technique, operating time, conversion, postoperative complications, length of hospital stay, number of lymph nodes, stage and involvement of margins. Significant differences were observed with regard to surgical time (224 min in the first group, 204 min in the second group), with a higher rate of conversion in the first group (22.5%) than in the second (11.3%). No significant differences were noted for rate of conservative sphincter surgery, length of hospital stay, post-surgical complications, number of affected/isolated lymph nodes or affected circumferential and distal margins. It is possible to learn this complex surgical technique without compromising the patient's safety and oncological outcome. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    It is well known that obesity has a multifactorial etiology, including biological, environmental, and psychological causes. For this reason, obesity treatment requires a more integrated approach than the standard behavioral treatment based on dietary and physical activity only. To test the long-term efficacy of an enhanced cognitive-behavioral therapy (CBT) of obesity, including a virtual reality (VR) module aimed at both unlocking the negative memory of the body and to modify its behavioral and emotional correlates, 163 female morbidly obese inpatients (body mass index >40) were randomly assigned to three conditions: a standard behavioral inpatient program (SBP), SBP plus standard CBT, and SBP plus VR-enhanced CBT. Patients' weight, eating behavior, and body dissatisfaction were measured at the start and upon completion of the inpatient program. Weight was assessed also at 1 year follow-up. All measures improved significantly at discharge from the inpatient program, and no significant difference was found among the conditions. However, odds ratios showed that patients in the VR condition had a greater probability of maintaining or improving weight loss at 1 year follow-up than SBP patients had (48% vs. 11%, p = 0.004) and, to a lesser extent, than CBT patients had (48% vs. 29%, p = 0.08). Indeed, only the VR-enhanced CBT was effective in further improving weight loss at 1 year follow-up. On the contrary, participants who received only the inpatient program regained back, on average, most of the weight they had lost. Findings support the hypothesis that a VR module addressing the locked negative memory of the body may enhance the long-term efficacy of standard CBT.

  3. CORRELATION OF NON-ALCOHOLIC FATTY LIVER DISEASE AND FEATURES OF METABOLIC SYNDROME IN MORBIDLY OBESE PATIENTS IN THE PREOPERATIVE ASSESSMENT FOR BARIATRIC SURGERY

    de BARROS, Fernando; SETÚBAL, Sergio; MARTINHO, José Manoel; FERRAZ, Loraine; GAUDÊNCIO, Andressa

    2016-01-01

    ABSTRACT Background: Obesity is an epidemic and chronic disease that can bring other comorbidities to the patient. Non-alcoholic fatty liver disease is present in up to 90% of these patients and can progress to hepatitis and hepatocarcinoma. The relationship of this liver disease and obesity is already well known; however, it is possible that some parameters of the comorbidities are more related than others in the pathophysiology of the disease. Aim: Was analyzed the relationship between non-alcoholic fatty liver disease (NAFLD) and the comorbidities of metabolic syndrome in morbidly obese patients. Methods: Was involved ultrasonography and laboratory assessment of obese patients before bariatric surgery. NAFLD was assessed using the same sonography parameters for all patients. Based on the results, the patients were divided into groups with and without NAFLD. Comparisons between them involved clinical and laboratory variables such as fasting blood glucose, insulin, HOMA-IR (homeostasis model assessment - insulin resistance), glycated hemoglobin, total cholesterol and fractions, triglycerides, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, C-reactive protein, albumin and ferritin. Patients who reported alcohol abuse (defined as the consumption of >14 drinks per week) or who had hepatitis were excluded. Results: Eighty-two patients (74 women and 8 men) were studied, of whom 53 (64.6%) had NAFLD and 29 (35.4%) did not. The levels of glycated hemoglobin (p=0.05) and LDL cholesterol (p=0.01) were significantly altered in patients with NAFLD. However, weight, body mass index and excess weight did not differ significantly between the groups (p=0.835, p=0.488 and p=0.727, respectively). Conclusions: Altered LDL cholesterol and glycated hemoglobin levels were related to the presence of NAFLD. PMID:28076482

    We aimed to evaluate the effects of the omega-3 supplementation on body weight and depression among women with co-morbidity of depression and obesity seeking weight reduction compared with the placebo. Sixty five patients with co-morbidity of depression and overweight/obesity (BMI ≥ 25) signed the informed consent form and enrolled into this 12-week double-blind, placebo-controlled randomized clinical Trial. Subsequently, participants randomly assigned into one of the two groups receiving daily 6 capsules of omega-3 (each capsule containing 180 mg EPA, and 120 mg DHA) or 6 capsules of placebo (two with each meal). We performed body composition assessments and Beck depression inventory at the baseline, and weeks 2, 4, 8, and 12 after the start of the study. One month after stopping the capsules at the follow-up visit, weight was measured to compare weight relapse between the two groups. Forty five patients finished the study. No significant differences were seen between groups regarding demographic and clinical variables at baseline. Using repeated measures ANOVA, omega-3 significantly reduced depression compared with the placebo (P = 0.05). Mean ± SD weight reduction in omega-3 group 3.07 ± 3.4 kg and in the placebo group was 1.16 ± 2.7 kg and the difference between groups was significant using independent sample t-test (p = 0.049). Patients in the omega-3 group did not show significantly more side effects compared to the placebo but they were not successful in preventing weight regain one month after the end of the study. Based on our findings omega-3 capsule as a safe over-the-counter supplement might be helpful in reducing the signs of depression and also body weight in patients with co-morbidity of depression and obesity.

    Recent reports indicate that laparoscopic cholecystectomy in pregnancy is safe. The aim of this study was to evaluate whether delays in definitive treatment of symptomatic cholelithiasis increase morbidity. We reviewed the records of 16 women who underwent laparoscopic cholecystectomy during pregnancy between 1992 and 1999. Mean age was 24 +/- 5 years (mean +/- standard error). Symptom onset was during the first trimester in nine patients, second trimester in six patients, and third trimester in one patient. Patients had abdominal pain (93%), nausea (93%), emesis (80%), and fever (66%) for a median of 45 days (range 1-195 days) before cholecystectomy. Nine of 11 women who underwent cholecystectomy more than 5 weeks after onset of symptoms experienced recurrent attacks necessitating 15 hospital admissions and four emergency room visits. Moreover four women who developed symptoms in the first and second trimesters but whose operations were delayed to the third trimester had 11 hospital admissions and four emergency room visits; three of those four (75%) women developed premature contractions necessitating tocolytics. Cholecystectomy was completed laparoscopically in 14 women. There was no hospital infant or maternal mortality or morbidity. We recommend prompt laparoscopic cholecystectomy in pregnant women with symptomatic biliary disease because it is safe and it reduces hospital admissions and frequency of premature labor.

  6. Zonulin transgenic mice show altered gut permeability and increased morbidity/mortality in the DSS colitis model.

    Increased small intestinal permeability (IP) has been proposed to be an integral element, along with genetic makeup and environmental triggers, in the pathogenies of chronic inflammatory diseases (CIDs). We identified zonulin as a master regular of intercellular tight junctions linked to the development of several CIDs. We aim to study the role of zonulin-mediated IP in the pathogenesis of CIDs. Zonulin transgenic Hp2 mice (Ztm) were subjected to dextran sodium sulfate (DSS) treatment for 7 days, followed by 4-7 days' recovery and compared to C57Bl/6 (wild-type (WT)) mice. IP was measured in vivo and ex vivo, and weight, histology, and survival were monitored. To mechanistically link zonulin-dependent impairment of small intestinal barrier function with clinical outcome, Ztm were treated with the zonulin inhibitor AT1001 added to drinking water in addition to DSS. We observed increased morbidity (more pronounced weight loss and colitis) and mortality (40-70% compared with 0% in WT) at 11 days post-DSS treatment in Ztm compared with WT mice. Both in vivo and ex vivo measurements showed an increased IP at baseline in Ztm compared to WT mice, which was exacerbated by DSS treatment and was associated with upregulation of zonulin gene expression (fourfold in the duodenum, sixfold in the jejunum). Treatment with AT1001 prevented the DSS-induced increased IP both in vivo and ex vivo without changing zonulin gene expression and completely reverted morbidity and mortality in Ztm. Our data show that zonulin-dependent small intestinal barrier impairment is an early step leading to the break of tolerance with subsequent development of CIDs. © 2017 New York Academy of Sciences.

  7. Psychosocial aspects of obesity.

    Vaidya, Varsha

    2006-01-01

    Obese patients have many physical limitations and much psychiatric burden to overcome. Several studies have shown that the prevalence of psychiatric morbidity in the obese is similar to those with normal weight. However, in obese patients seeking treatment there is an increased prevalence (40-60%) of psychiatric morbidity, most commonly depression. It is difficult to separate the effects of depression on obesity and, on the contrary, the neuroendocrine changes associated with stress and depression may cause metabolic changes that predispose and perpetuate obesity. The stigma associated with obesity causes bullying in school as well as childhood psychiatric morbidity. Prejudice is not limited to the general public but exists among health professionals too. This chapter discusses the treatment of depression in obesity and the psychiatric evaluation of the pre-bariatric surgery patient. Education of society, starting with schools and including healthcare professionals will reduce bias and stigma as well as assist this vulnerable group of patients to seek help for their obesity and the many problems that come with it. Given that by the year 2025 obesity will be the world's number one health problem with the US leading the way, it is very important that we pursue preventive measures as well as encourage research for treatments of obesity.

  8. Interventions targeted at primary care practitioners to improve the identification and referral of patients with co-morbid obesity: a realist review protocol.

    2015-05-01

    Obesity is one of the most significant public health challenges in the developed world. Recent policy has suggested that more can be done in primary care to support adults with obesity. In particular, general practitioners (GPs) and practice nurses (PNs) could improve the identification and referral of adults with obesity to appropriate weight management services. Previous interventions targeted at primary care practitioners in this area have had mixed results, suggesting a more complex interplay between patients, practitioners, and systems. The objectives of this review are (i) to identify the underlying 'programme theory' of interventions targeted at primary care practitioners to improve the identification and referral of adults with obesity and (ii) to explore how and why GPs and PNs identify and refer individuals with obesity, particularly in the context of weight-related co-morbidity. This protocol will explain the rationale for using a realist review approach and outline the key steps in this process. Realist review is a theory-led approach to knowledge synthesis that provides an explanatory analysis aimed at discerning what works, for whom, in what circumstances, how, and why. In this review, scoping interviews with key stakeholders involved in the planning and delivery of adult weight management services in Scotland helped to inform the identification of formal theories - from psychology, sociology, and implementation science - that will be tested as the review progresses. A comprehensive search strategy is described, including scope for iterative searching. Data analysis is outlined in three stages (describing context-mechanism-outcome configurations, exploring patterns in these configurations, and developing and testing middle-range theories, informed by the formal theories previously identified), culminating in the production of explanatory programme theory that considers individual, interpersonal, and institutional/systems-level components. This is the

    The present study was conducted in order to analyze the relationship existing between leptin and insulin levels in massive weight loss and weight recovery. Thirteen patients with severe obesity, 14 patients with anorexia nervosa and 13 healthy control subjects were studied. The patients with severe obesity underwent a vertical banded gastroplasty followed by an 800 kcal/day diet for 12 weeks. They were evaluated prior to (body mass index [BMI] 51.2 +/- 8.8 Kg/m2) and after drastic weight loss (BMI 40.6 +/- 6.7 Kg/m2). Patients with anorexia nervosa were treated exclusively with nutritional therapy during 12 weeks, and they were evaluated at their lowest weight status (BMI 16.2 +/- 2.2 Kg/m2) and after weight recovery (BMI 17.9 +/- 2.3 Kg/m2). The BMI of the normal subjects was in the normal range of 20 to 27 Kg/m2 (average 22.8 +/- 2.6 Kg/m2). BMI, percentage of body fat, waist circumference, and serum levels of leptin, insulin, and C-peptide were determined in each patient and normal subject. In severely obese patients, serum leptin and insulin decreased significantly after drastic weight reduction (leptin: from 51.8 +/- 22.3 to 23.7 +/- 10.2 ng/ml; insulin: from 27.1 +/- 13.3 to 17.2 +/- 7.2 mU/ml). In patients with anorexia nervosa, the mean serum leptin levels were significantly higher after weight recovery (5.5 +/- 3.2 vs 7.6 +/- 6 ng/ml). Serum leptin in the severe obesity group correlated positively with BMI, percentage body fat and waist circumference before and after weight loss. In those patients suffering from anorexia nervosa, serum leptin correlated positively with the BMI, percentage of body fat, and waist circumference in the low weight state and after weight recovery. In addition, their serum insulin correlated with BMI and waist circumference after weight recovery. These data reveal that serum leptin concentration correlates significantly with the BMI and body fat content 1) in subjects with a range of weight and caloric intake, 2) in obese

    2015-08-01

    To identify possible mechanisms linking obesity in pregnancy to increased fetal adiposity and growth, a unique mouse model of maternal obesity associated with fetal overgrowth was developed, and the hypothesis that maternal obesity causes up-regulation of placental nutrient transporter expression and activity was tested. C57BL/6J female mice were fed a control (C) or a high-fat/high-sugar (HF/HS) pelleted diet supplemented by ad libitum access to sucrose (20%) solution, mated, and studied at embryonic day 18.5. HF/HS diet increased maternal fat mass by 2.2-fold (P Maternal circulating insulin, leptin, and cholesterol were increased (P maternal obesity. © 2015 The Obesity Society.

  11. Increases of Obesity and Overweight in Children: an Alarm for Parents and Policymakers

    Gholam Hasan Khadaee

    2016-04-01

    Full Text Available Childhood obesity is one of the most serious public health challenges of the 21st century. The problem is global and is steadily affecting many low- and middle-income countries, particularly in urban settings. The prevalence has increased at an alarming rate. Globally, in 2013 the number of overweight children under the age of five years old, is estimated to be over 42 million. Close to 31 million of these are living in developing countries. In the WHO African Region alone the number of overweight or obese children increased from 4 to 9 million over the same period. The vast majority of overweight or obese children live in developing countries, where the rate of increase has been more than 30% higher than that of developed countries. If current trends continue the number of overweight or obese infants and young children globally will increase to 70 million by 2025.  Without intervention, obese infants and young children will likely continue to be obese during childhood, adolescence and adulthood. Overweight and obesity are largely preventable. Supportive policies, environments, schools and communities are fundamental in shaping parents’ and children’s choices, making the healthier choice of foods and regular physical activity the easiest choice (accessible, available and affordable, and therefore preventing obesity.

    We measured plasma bile acids, markers of bile acid synthesis, and expression of bile acid transporters in obese and nonobese subjects. We found that obesity was associated with increased bile acid synthesis and 12-hydroxylation, blunted response of plasma bile acids to insulin infusion or a mixed meal, and decreased expression of liver bile acid transporters.

    2016-04-01

    There is ongoing controversy as to whether obesity confers risk for CAD independently of associated risk factors including diabetes mellitus. We have carried out a Mendelian randomization study using a genetic risk score (GRS) for body mass index (BMI) based on 35 risk alleles to investigate this question in a population of 5831 early onset CAD cases without diabetes mellitus and 3832 elderly healthy control subjects, all of strictly European ancestry, with adjustment for traditional risk factors (TRFs). We then estimated the genetic correlation between these BMI and CAD (rg) by relating the pairwise genetic similarity matrix to a phenotypic covariance matrix between these two traits. GRSBMI significantly (P=2.12 × 10(-12)) associated with CAD status in a multivariate model adjusted for TRFs, with a per allele odds ratio (OR) of 1.06 (95% CI 1.042-1.076). The addition of GRSBMI to TRFs explained 0.75% of CAD variance and yielded a continuous net recombination index of 16.54% (95% CI=11.82-21.26%, P<0.0001). To test whether GRSBMI explained CAD status when adjusted for measured BMI, separate models were constructed in which the score and BMI were either included as covariates or not. The addition of BMI explained ~1.9% of CAD variance and GRSBMI plus BMI explained 2.65% of CAD variance. Finally, using bivariate restricted maximum likelihood analysis, we provide strong evidence of genome-wide pleiotropy between obesity and CAD. This analysis supports the hypothesis that obesity is a causal risk factor for CAD.

    According to the developmental origins of health and diseases (DOHaD), and in line with the findings of many studies, obesity during pregnancy is clearly a threat to the health and well-being of the offspring, later in adulthood. We previously showed that 20% of male and female inbred mice can cope with the obesogenic effects of a high-fat diet (HFD) for 20 weeks after weaning, remaining lean. However the feeding of a control diet (CD) to DIO mice during the periconceptional/gestation/lactation period led to a pronounced sex-specific shift (17% to 43%) from susceptibility to resistance to HFD, in the female offspring only. Our aim in this study was to determine how, in the context of maternal obesity and T2D, a CD could increase resistance on female fetuses. Transcriptional analyses were carried out with a custom-built mouse liver microarray and by quantitative RT-PCR for muscle and adipose tissue. Both global DNA methylation and levels of pertinent histone marks were assessed by LUMA and western blotting, and the expression of 15 relevant genes encoding chromatin-modifying enzymes was analyzed in tissues presenting global epigenetic changes. Resistance was associated with an enhancement of hepatic pathways protecting against steatosis, the unexpected upregulation of neurotransmission-related genes and the modulation of a vast imprinted gene network. Adipose tissue displayed a pronounced dysregulation of gene expression, with an upregulation of genes involved in lipid storage and adipocyte hypertrophy or hyperplasia in obese mice born to lean and obese mothers, respectively. Global DNA methylation, several histone marks and key epigenetic regulators were also altered. Whether they were themselves lean (resistant) or obese (sensitive), the offspring of lean and obese mice clearly differed in terms of several metabolic features and epigenetic marks suggesting that the effects of a HFD depend on the leanness or obesity of the mother.

  16. Endoscopic Management of Drain Inclusion in the Gastric Pouch after Gastrojejunal Leakage after Laparoscopic Roux-en-Y Gastric Bypass for the Treatment of Morbid Obesity (LRYGBP

    Patients. All four obese morbidly patients underwent LRYGBP and presented a gastro-jejunal fistula after acute anastomotic leakage. During follow-up endoscopy the drain was found inside the gastric pouch. It was moved into the abdominal cavity. Fistula debit reduced significantly and closed. Results. Gastric leak closure in less than 24 hours was achieved in all, with complete resolution of symptoms. These patients benefited exclusively from endoscopic treatment. Conclusions. Endoscopy is useful and technically feasible in chronic fistulas. This procedure is a less invasive alternative to traditional surgical revision. Other therapeutic strategies can be used such as clips and fibrin glue. Drains should not be placed in contact with the anastomosis or stapled lines. Drain inclusion must be suspected when fistula debit suddenly arises. If so, endoscopy is indicated for diagnostic accuracy. Under endoscopy vision, the drain is gently removed from the gastric reservoir leading to sudden and complete resolution of the fistula.

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

    Obesity is an epidemic in the pediatric population. Childhood obesity in trauma has been associated with increased incidence of long-bone fractures, longer ICU stays, and decreased closed head injuries. We investigated for differences in the likelihood of failure of non-operative management (NOM), and injury grade using a subset of a multi-institutional, prospective database of pediatric patients with solid organ injury (SOI). We prospectively collected data on all pediatric patients (hepatic injury (36.8% versus 15.3%, P=0.048) but not a significant difference in likelihood of severe (grade 4 or 5) splenic injury (15.3% versus 10.5%, P=0.736). Obese patients had a higher mean ISS (22.5 versus 16.1, P=0.021) and mean abdominal AIS (3.5 versus 2.9, P=0.024). Obesity is a risk factor for more severe abdominal injury, specifically liver injury, but without an associated increase in failure of NOM. This may be explained by the presence of hepatic steatosis making the liver more vulnerable to injury. A protocol based upon physiologic parameters was associated with a low rate of failure regardless of the pediatric obesity status. Level II prognosis. Copyright © 2016 Elsevier Inc.

    Full Text Available Context It is unclear whether health-related quality of life (HRQL is sustained in a long-term follow-up of morbidly obese patients who underwent Roux-en-Y gastric bypass (RYGB. Objective This study aims to analyze the HRQL changes following RYGB in short and long-term follow-up. Methods We compared the health-related quality of life among three separate patient groups, using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36. Group A - 50 preoperative morbidly obese patients; Group B - 50 RYGB patients 1-2 years post-surgery; Group C - 50 RYGB patients more than 7 years post-surgery. Results The groups were similar for gender, age and body mass index before surgery. We observed that physical functioning, social function, emotional role functioning and mental health scales did not vary between the three groups. The physical role functioning scale was unchanged in the short-term and decreased compared to the preoperative scale in the long-term follow-up. Bodily pain improved after the operation but returned to the initial level after 7 years. The vitality and general health perceptions improved after the operation and maintained these results after 7 years compared with the preoperative perceptions. Conclusions RYGB improved health-related quality of life in three SF-36 domains (bodily pain, general health perceptions and vitality in the short-term and two SF-36 domains (general health perceptions and vitality in the long-term.

  20. Circulating sCD36 is associated with unhealthy fat distribution and elevated circulating triglycerides in morbidly obese individuals

  1. Natural killer cells in obesity: impaired function and increased susceptibility to the effects of cigarette smoke.

    O'Shea, Donal

    2012-02-01

    BACKGROUND: Obese individuals who smoke have a 14 year reduction in life expectancy. Both obesity and smoking are independently associated with increased risk of malignancy. Natural killer cells (NK) are critical mediators of anti-tumour immunity and are compromised in obese patients and smokers. We examined whether NK cell function was differentially affected by cigarette smoke in obese and lean subjects. METHODOLOGY AND PRINCIPAL FINDINGS: Clinical data and blood were collected from 40 severely obese subjects (BMI>40 kg\\/m(2)) and 20 lean healthy subjects. NK cell levels and function were assessed using flow cytometry and cytotoxicity assays. The effect of cigarette smoke on NK cell ability to kill K562 tumour cells was assessed in the presence or absence of the adipokines leptin and adiponectin. NK cell levels were significantly decreased in obese subjects compared to lean controls (7.6 vs 16.6%, p = 0.0008). NK function was also significantly compromised in obese patients (30% +\\/- 13% vs 42% +\\/-12%, p = 0.04). Cigarette smoke inhibited NK cell ability to kill tumour cell lines (p<0.0001). NK cells from obese subjects were even more susceptible to the inhibitory effects of smoke compared to lean subjects (33% vs 28%, p = 0.01). Cigarette smoke prevented NK cell activation, as well as perforin and interferon-gamma secretion upon tumour challenge. Adiponectin but not leptin partially reversed the effects of smoke on NK cell function in both obese (p = 0.002) and lean controls (p = 0.01). CONCLUSIONS\\/SIGNIFICANCE: Obese subjects have impaired NK cell activity that is more susceptible to the detrimental effects of cigarette smoke compared to lean subjects. This may play a role in the increase of cancer and infection seen in this population. Adiponectin is capable of restoring NK cell activity and may have therapeutic potential for immunity in obese subjects and smokers.

    2017-04-01

    This study was designed to investigate whether an elevated fasting insulin level predicts abdominal obesity. A cohort study was conducted with 13,707 non-obese Korean men. They were categorized into 4 groups according to the quartile of fasting insulin level, and followed up from 2005 to 2010. Incidence rates of obesity were compared among the 4 groups during follow-up, and a Cox proportional hazards model was used to calculate hazard ratios (HRs) for abdominal obesity according to fasting insulin level. The overall incidence rate of obesity was 16.2%, but the rate increased in proportion to the fasting insulin level (quartiles 1-4: 9.8%, 12.4%, 16.9%, 25.5%, Pobesity increased proportionally to baseline fasting insulin level in an unadjusted model. However, after adjustment for covariates, including baseline waist circumference (WC), only in the quartile 4 group was the statistical significance of the association maintained [quartile 2-4; abdominal obesity: 0.89 (0.76-1.02), 1.00 (0.86-1.14) and 1.24 (1.08-1.43), P for trend obesity was highest in the group with the highest fasting insulin levels, an overall proportional relationship between fasting insulin level and incident abdominal obesity was not found. Additionally, this association was largely accounted for by baseline WC. Copyright © 2017 Elsevier B.V. All rights reserved.

    To explore relationships of socio-demographic variables, health behaviours, environmental characteristics and personal factors, with physical and mental health variables in persons with morbid obesity, and to compare their health-related quality of life (HRQoL) scores with scores from the general population. A cross-sectional correlation study design was used. Data were collected by self-reported questionnaire from adult patients within the first 2 days of commencement of a mandatory educational course. Of 185 course attendees, 142 (76.8%) volunteered to participate in the study. Valid responses on all items were recorded for 128 participants. HRQoL was measured with the Short Form 12v2 from which physical (PCS) and mental component summary (MCS) scores were computed. Other standardized instruments measured regular physical activity, social support, self-esteem, sense of coherence, self-efficacy and coping style. Respondents scored lower on all the HRQoL sub-domains compared with norms. Linear regression analyses showed that personal factors that included self-esteem, self-efficacy, sense of coherence and coping style explained 3.6% of the variance in PCS scores and 41.6% in MCS scores. Personal factors such as self-esteem, sense of coherence and a high approaching coping style are strongly related to mental health in obese persons.

  7. Childhood obesity: a review of increased risk for physical and psychological comorbidities.

    Pulgarón, Elizabeth R

    2013-01-01

    Worldwide estimates of childhood overweight and obesity are as high as 43 million, and rates continue to increase each year. Researchers have taken interest in the childhood obesity epidemic and the impact of this condition across health domains. The consequences of childhood and adolescent obesity are extensive, including both medical and psychosocial comorbidities. The purpose of this review was to consolidate and highlight the recent literature on the comorbidities associated with childhood obesity, both nationally and internationally. PubMed and PsychINFO searches were conducted on childhood obesity and comorbidities. The initial search of the terms obesity and comorbidity yielded >5000 published articles. Limits were set to include studies on children and adolescents that were published in peer-reviewed journals from 2002 to 2012. These limits narrowed the search to 938. Review of those articles resulted in 79 that are included in this review. The major medical comorbidities associated with childhood obesity in the current literature are metabolic risk factors, asthma, and dental health issues. Major psychological comorbidities include internalizing and externalizing disorders, attention-deficit hyperactivity disorder, and sleep problems. The high prevalence rates of childhood obesity have resulted in extensive research in this area. Limitations to the current childhood obesity literature include differential definitions of weight status and cut-off levels for metabolic risk factors across studies. Additionally, some results are based on self-report of diagnoses rather than chart reviews or physician diagnosis. Even so, there is substantial support for metabolic risk factors, internalizing disorders, attention-deficit hyperactivity disorder, and decreased health-related quality of life as comorbidities to obesity in childhood. Additional investigations on other diseases and conditions that might be associated with childhood obesity are warranted and

  8. Increased leucocyte Na-K ATPase in obesity: reversal following weight loss

    Turaihi, K.; Baron, D.N.; Dandona, P.

    1987-01-01

    Ouabain-sensitive 86 Rb influx and [ 3 H] ouabain binding capacity were investigated in the leucocytes of 17 obese patients and 15 control subjects. Both were significantly increased in the obese when compared with controls. Following dietary restriction and a 4% to 5% weight reduction in the obese over 2 weeks, [ 3 H] ouabain binding and ouabain-sensitive 86 Rb influx (a model for K+ influx) decreased to levels similar to those in controls. This shows that the number of Na-K ATPase sites on leucocyte membranes of the obese are significantly increased and that this is associated with accelerated 86 Rb transport. Since both of these indices decreased following 4% to 5% reduction in body weight while the patients were still obese, increased Na-K ATPase is neither a marker of nor cardinal to the pathogenesis of obesity. We conclude that (1) increase in Na-K ATPase units and 86 Rb influx are not characteristic of obesity itself and (2) dietary restriction over the short-term with limited weight reduction restores Na-K ATPase units and 86 Rb influx to normal

  10. Does the presence of placental basal plate myometrial fibres increase the risk of subsequent morbidly adherent placenta: a case-control study.

    Miller, E S; Linn, R L; Ernst, L M

    2016-12-01

    Antenatal diagnosis of morbidly adherent placenta has been shown to improve outcomes, but existing predictors lack sensitivity. Our objective was to determine whether the presence of myometrial fibres attached to the placental basal plate (BPMYO) in an antecedent pregnancy is associated with subsequent morbidly adherent placenta. A case-control study. Departments of Obstetrics and Gynecology and Pathology, Northwestern University, Chicago, IL, USA. Women who had at least two pregnancies with placental pathological evaluation. Cases were defined as women with evidence of morbidly adherent placenta (both clinically and pathologically) in their most recent pregnancy whereas women without evidence of morbidly adherent placenta served as controls. Pathological specimens of placentas from previous pregnancies were evaluated for BPMYO. The presence of BPMYO on a previous placenta was evaluated to determine whether it could be used to improve the antenatal diagnosis of morbidly adherent placenta. Of the 25 cases of morbidly adherent placenta, 19 (76%) had BPMYO present on their previous placenta compared with 41 (41%) of controls (odds ratio 4.8, 95% CI 1.8-13.0). Adding BPMYO to a regression including other risk factors for morbidly adherent placenta (i.e. maternal age, number of previous caesarean sections, placenta praevia, previous multiple gestation, any previous curettage, and ultrasonographic suspicion of placenta accreta) significantly improved the sensitivity of antenatal diagnosis of morbidly adherent placenta (61% versus 39%, P placental pathology is associated with an increased risk of morbidly adherent placenta in a subsequent pregnancy. These findings may shed light on the pathophysiology of accreta and inform future research on predictors of accreta.

  11. Does maternal psychopathology increase the risk of pre-schooler obesity? A systematic review.

    Benton, Pree M; Skouteris, Helen; Hayden, Melissa

    2015-04-01

    The preschool years may be a critical period for child obesity onset; however, literature examining obesity risk factors to date has largely focused on school-aged children. Several links have been made between maternal depression and childhood obesity risks; however, other types of maternal psychopathology have been widely neglected. The aim of the present review was to systematically identify articles that examined relationships between maternal psychopathology variables, including depressive and anxiety symptoms, self-esteem and body dissatisfaction, and risks for pre-schooler obesity, including weight outcomes, physical activity and sedentary behaviour levels, and nutrition/diet variables. Twenty articles meeting review criteria were identified. Results showed positive associations between maternal depressive symptoms and increased risks for pre-schooler obesity in the majority of studies. Results were inconsistent depending on the time at which depression was measured (i.e., antenatal, postnatal, in isolation or longitudinally). Anxiety and body dissatisfaction were only measured in single studies; however, both were linked to pre-schooler obesity risks; self-esteem was not measured by any studies. We concluded that maternal depressive symptoms are important to consider when assessing risks for obesity in preschool-aged children; however, more research is needed examining the impact of other facets of maternal psychopathology on obesity risk in pre-schoolers.

  12. [Endocrine function in obesity].

    Álvarez-Castro, Paula; Sangiao-Alvarellos, Susana; Brandón-Sandá, Iria; Cordido, Fernando

    2011-10-01

    Obesity is associated to significant disturbances in endocrine function. Hyper insulinemia and insulin resistance are the best known changes in obesity, but their mechanisms and clinical significance are not clearly established. Adipose tissue is considered to be a hormone-secreting endocrine organ; and increased leptin secretion from the adipocyte, a satiety signal, is a well-established endocrine change in obesity. In obesity there is a decreased GH secretion. Impairment of somatotropic function in obesity is functional and may be reversed in certain circumstances. The pathophysiological mechanism responsible for low GH secretion in obesity is probably multifactorial. There are many data suggesting that a chronic state of somatostatin hypersecretion results in inhibition of GH release. Increased FFA levels, as well as a deficient ghrelin secretion, probably contribute to the impaired GH secretion. In women, abdominal obesity is associated to hyperandrogenism and low sex hormone-binding globulin levels. Obese men, particularly those with morbid obesity, have decreased testosterone and gonadotropin levels. Obesity is associated to an increased cortisol production rate, which is compensated for by a higher cortisol clearance, resulting in plasma free cortisol levels that do not change when body weight increases. Ghrelin is the only known circulating orexigenic factor, and has been found to be decreased in obese people. In obesity there is also a trend to increased TSH and free T3 levels.

  13. Cold-increase in brown fat thyroxine 5'-monodeiodinase is attenuated in Zucker obese rat

    Wu, S.Y.; Stern, J.S.; Fisher, D.A.; Glick, Z.

    1987-01-01

    In this study the authors examined the possibility that the reduced brown adipose tissue (BAT) thermogenesis in the Zucker obese rat may result from a limited capacity for enzymic conversion of thyroxine (T 4 ) to triiodothyronine (T 3 ) in BAT. A total of 34 lean and obese rats, ∼4 mo old were divided into three treatment groups: group 1 (5 lean and 6 obese) was fed Purina rat chow for 21 days, and group two (5 lean and 6 obese) was fed a cafeteria diet for 21 days, and groups 3 (6 lean and 6 obese) was fed Purina rat chow and maintained in the cold (8 +/- 1 0 C) for 7 days. Activity of T 4 5'-deiodinase was determined as the rate of T 3 production from added T 4 under controlled in vitro conditions. Serum T 4 and T 3 were determined by radioimmunoassay. The rate of T 4 -to-T 3 conversion in BAT was similar in the lean and obese rats maintained at room temperature, whether fed rat chow or a cafeteria diet. However, expressed per scapular BAT depot, lean rats exposed to cold displayed about a fivefold increase in BAT T 3 production whereas only a small increase was observed in the cold-exposed obese rats. Serum T 3 levels tended to be reduced in the Zucker obese rats. The data indicate a reduced capacity for T 3 production of Zucker rat BAT exposed to cold. This defect may account for the reduced tolerance of the obese animals to cold, but it does not account for their reduced diet-induced BAT thermogenesis

  14. Effects of a balanced energy and high protein formula diet (Vegestart complet®) vs. low-calorie regular diet in morbid obese patients prior to bariatric surgery (laparoscopic single anastomosis gastric bypass): a prospective, double-blind randomized study.

    Bariatric surgery is considered the only therapeutic alternative for morbid obesity and its comorbidities. High risks factors are usually linked with this kind of surgery. In order to reduce it, we consider that losing at least 10% of overweight in Morbid Obese (MO) and a minimum of 20% in Super- Obese patients (SO) before surgery, may reduce the morbidity of the procedure. The aim of our study is to demonstrate the effectiveness and tolerance of a balanced energy formula diet at the preoperative stage, comparing it against a low calorie regular diet. We studied 120 patients divided into two groups of 60 each, group A was treated 20 days prior to bariatric surgery with a balanced energy formula diet, based on 200 Kcal every 6 hours for 12 days and group B was treated with a low calorie regular diet with no carbs or fat. The last eight days prior to surgery both groups took only clear liquids. We studied the evolution of weight loss, the BMI, as well as behavior of co-morbidities as systolic blood pressure, diastolic blood pressure, glucose controls and tolerance at the protocol. The study shows that patients undergoing a balanced energy formula diet improved their comorbidities statistically significant in terms of decrease in weight and BMI loss, blood pressure and glucose, compared to the group that was treated before surgery with a low calorie regular diet. Nevertheless both groups improving the weight loss and co-morbidities with better surgical results and facilities. A correct preparation of the Morbid Obese patients prior of surgery can reduce the operative risks improving the results. Our study show that the preoperative treatment with a balanced energy formula diet as were included in our protocol in patients undergoing bariatric surgery improves statistical better their overall conditions, lowers cardiovascular risk and metabolic diseases that the patients with regular diet alone.

  15. Uric Acid Secretion from Adipose Tissue and Its Increase in Obesity*

    Obesity is often accompanied by hyperuricemia. However, purine metabolism in various tissues, especially regarding uric acid production, has not been fully elucidated. Here we report, using mouse models, that adipose tissue could produce and secrete uric acid through xanthine oxidoreductase (XOR) and that the production was enhanced in obesity. Plasma uric acid was elevated in obese mice and attenuated by administration of the XOR inhibitor febuxostat. Adipose tissue was one of major organs that had abundant expression and activities of XOR, and adipose tissues in obese mice had higher XOR activities than those in control mice. 3T3-L1 and mouse primary mature adipocytes produced and secreted uric acid into culture medium. The secretion was inhibited by febuxostat in a dose-dependent manner or by gene knockdown of XOR. Surgical ischemia in adipose tissue increased local uric acid production and secretion via XOR, with a subsequent increase in circulating uric acid levels. Uric acid secretion from whole adipose tissue was increased in obese mice, and uric acid secretion from 3T3-L1 adipocytes was increased under hypoxia. Our results suggest that purine catabolism in adipose tissue could be enhanced in obesity. PMID:23913681

  16. Increasing awareness in African American BSN students of the health risks of obesity.

    Williamson, Wanda; Kautz, Donald D

    2013-01-01

    This paper reports on the perceived effectiveness of a program to increase awareness of the health risks of obesity among African-American students. Thirty (n = 30) senior level Bachelor of Science in Nursing students attending a Historically Black College and University (HBCU) took a knowledge test, then participated in an hour-long educational session on obesity. Following the session, the students completed a 10-item post-test to evaluate the effectiveness of the program in increasing awareness of obesity as a risk for heart disease and diabetes. The findings suggested a need to further educate African-American students on the consequences of obesity as well as recommendations to advance the science of personal and family risk awareness in nursing students.

  17. Increased Morbidity and Mortality in Domestic Animals Eating Dropped and Bitten Fruit in Bangladeshi Villages: Implications for Zoonotic Disease Transmission.

    2016-03-01

    We used data on feeding practices and domestic animal health gathered from 207 Bangladeshi villages to identify any association between grazing dropped fruit found on the ground or owners directly feeding bat- or bird-bitten fruit and animal health. We compared mortality and morbidity in domestic animals using a mixed effects model controlling for village clustering, herd size, and proxy measures of household wealth. Thirty percent of household heads reported that their animals grazed on dropped fruit and 20% reported that they actively fed bitten fruit to their domestic herds. Household heads allowing their cattle to graze on dropped fruit were more likely to report an illness within their herd (adjusted prevalence ratio 1.17, 95% CI 1.02-1.31). Household heads directly feeding goats bitten fruit were more likely to report illness (adjusted prevalence ratio 1.35, 95% CI 1.16-1.57) and deaths (adjusted prevalence ratio 1.64, 95% CI 1.13-2.4). Reporting of illnesses and deaths among goats rose as the frequency of feeding bitten fruit increased. One possible explanation for this finding is the transmission of bat pathogens to domestic animals via bitten fruit consumption.

    2015-10-01

    The main aim of this study was to evaluate the relationship between obesity and renal involvement in children with Henoch-Schönlein purpura (HSP). A retrospective study of 141 pediatric patients with HSP was conducted in our hospital. The clinical data of all patients were collected from the electronic medical record management system from January 2010 to June 2014. The possible risk factors of renal involvement, especially obesity, were analyzed using univariate and multivariate analyses. Renal involvement occurred in 45/141 of the patients. A univariate analysis showed that an age more than 7 years at onset, persistent purpura, obesity, time from symptoms onset to diagnosis more than 14 days, and decreased C3 all increased the risk of renal involvement in HSP. The forward stepwise logistic regression analysis indicated obesity (odds ratio (OR) 4.43, 95 % confidence interval (CI) 1.896 to 10.358), age more than 7 years at onset (OR 2.81, 95 % CI 1.142 to 6.907), and persistent purpura (OR 2.57, 95 % CI 1.119 to 5.909) were independent risk factors for renal involvement. Our results show that obesity can increase the hazard of renal involvement in children with HSP and reconfirm that older age at onset and persistent purpura are the independent risk factors for renal involvement. • There have been some reports that obesity was associated with the development of renal injury. • It is not clear whether obesity can increase the risk of renal involvement in children with HSP. What is New: • The main finding of this study is that obesity can increase the hazard of renal involvement in children with HSP.

    The anatomical and physiological changes after Roux-en-Y gastric bypass for morbid obesity can lead to severe hyperinsulinemic hypoglycemia with neuroglycopenia in a small percentage of patients. The exact physiologic mechanism is not completely understood. Surgical reversal to the original anatomy and distal or total pancreatectomy are current therapeutic options to reverse the hypoglycemic effect, with substantial associated morbidity. Our group reports a pilot clinical series of a novel surgical technique using one-anastomosis jejunal interposition with gastric remnant resection (Branco-Zorron Switch). Patients with severe symptomatic hyperinsulinemic hypoglycemia refractory to conservative therapy were treated using the technique. The procedure started with resection of the remnant stomach close to pylorus. The alimentary limb was sectioned at 20 cm from the gastrojejunal anastomosis, and the rest of the alimentary limb was resected until the Y-Roux anastomosis. A hand-sutured anastomosis was then performed with the proximal alimentary limb and the remnant antrum. Four patients were successfully submitted to the procedure with reversal of the symptomatology and normalization of insulin levels, postprandial glucose levels, and oral glucose tolerance test, with a mean follow-up of 24.3 months. Mean operative time was 188 min, and patients recovered without postoperative complications. Patients suffering from severe hyperinsulinemic hypoglycemia after gastric bypass may be efficiently treated by this innovative procedure, avoiding extreme surgical therapy such as pancreatectomy or restoring the gastric anatomy, while still maintaining sustained weight loss. Studies with larger series and longer follow-up are still needed to define the role of this therapy in managing this entity.

  20. Obesity and bone.

    Compston, Juliet

    2013-03-01

    Recent studies indicate that fractures in obese postmenopausal women and older men contribute significantly to the overall fracture burden. The effect of obesity is to some extent site-dependent, the risk being increased for some fractures and decreased for others, possibly related to different patterns of falling and the presence or absence of soft tissue padding. Risk factors for fracture in obese individuals appear to be similar to those in the nonobese population, although falls may be particularly important in the obese. There is some evidence that the morbidity associated with fractures in obese individuals is greater than in the nonobese; however, a recent study indicates that the mortality associated with fracture is lower in obese and overweight people than in those of normal weight. The evidence base for strategies to prevent fractures in obese individuals is weak and is an important area for future research.

    Obese children are often taller than age-matched subjects. Reports on GH and IGF-I levels in obese individuals are controversial, with normal and reduced GH-IGF-I levels having been reported in this group of patients. Thus, the aim of this study was to analyse insulin-like growth factor type 1 receptor (IGF-IR) mRNA expression in obese children. Forty-seven pre-pubertal children were included in this study: 29 were obese and taller than their target height, and 18 were normal eutrophic controls. Fasting blood samples were collected for IGF-IR mRNA expression in isolated lymphocytes and serum IGF-I, ALS, IGFBP-3, and IGFBP-1 concentration analysis. Relative IGF-IR gene expression (2 -ΔΔCT ) was significantly (P=0.025) higher in obese children (median 1.87) than in controls (1.15). Fourteen of the 29 obese subjects showed 2 -ΔΔCT values greater than or equal to 2, while only 2 individuals in the control group showed values above 2 (P=0.01). Obese children showed significantly (P=0.01) higher IGF-I concentrations than the control group (237ng/ml and 144ng/ml, respectively). Among obese patients, 65.5% had IGF-I values above the 75 percentile of the control group (P=0.02). ALS concentration was significantly (P=0.04) higher in the obese group, while IGFBP-3 levels were similar in obese and control children. IGFBP-1 concentration was lower in obese children, while insulin levels and HOMA-IR index were higher than in controls. The higher IGF-IR mRNA expression observed in obese children, associated with the higher IGF-I and ALS and the lower IGFBP-1 levels, suggest that the higher stature observed in these children may be due to increased IGF-I bioactivity.

    Full Text Available Abstract Background The health condition of workers is known to impact on productivity outcomes. The relationship between health and productivity is of increasing interest amid the need to increase productivity to meet global financial challenges. Prevalence of psychological distress is also of growing concern in Australia with a two-fold increase in the prevalence of psychological distress in Australia from 1997-2005. Methods We used the cross-sectional data set from the Australian Work Outcomes Research Cost-benefit (WORC study to explore the impacts of health conditions with and without co-morbid psychological distress, compared to those with neither condition, in a sample of approximately 78,000 working Australians. The World Health Organisation Health and Performance Questionnaire was used which provided data on demographic characteristics, health condition and working conditions. Data were analysed using negative binomial logistic regression and multinomial logistic regression models for absenteeism and presenteeism respectively. Results For both absenteeism and presenteeism productivity measures there was a greater risk of productivity loss associated when health conditions were co-morbid with psychological distress. For some conditions this risk was much greater for those with co-morbid psychological distress compared to those without. Conclusions Co-morbid psychological distress demonstrates an increased risk of productivity loss for a range of health conditions. These findings highlight the need for further research to determine whether co-morbid psychological distress potentially exacerbates lost productivity.

    Purpose To evaluate the diagnostic performance and examination success rate of magnetic resonance (MR) elastography and vibration-controlled transient elastography (VCTE) in the detection of hepatic fibrosis in patients with severe to morbid obesity. Materials and Methods This prospective and HIPAA-compliant study was approved by the institutional review board. A total of 111 patients (71 women, 40 men) participated. Written informed consent was obtained from all patients. Patients underwent MR elastography with two readers and VCTE with three observers to acquire liver stiffness measurements for liver fibrosis assessment. The results were compared with those from liver biopsy. Each pathology specimen was evaluated by two hepatopathologists according to the METAVIR scoring system or Brunt classification when appropriate. All imaging observers were blinded to the biopsy results, and all hepatopathologists were blinded to the imaging results. Examination success rate, interobserver agreement, and diagnostic accuracy for fibrosis detection were assessed. Results In this obese patient population (mean body mass index = 40.3 kg/m 2 ; 95% confidence interval [CI]: 38.7 kg/m 2 , 41.8 kg/m 2 ]), the examination success rate was 95.8% (92 of 96 patients) for MR elastography and 81.3% (78 of 96 patients) or 88.5% (85 of 96 patients) for VCTE. Interobserver agreement was higher with MR elastography than with biopsy (intraclass correlation coefficient, 0.95 vs 0.89). In patients with successful MR elastography and VCTE examinations (excluding unreliable VCTE examinations), both MR elastography and VCTE had excellent diagnostic accuracy in the detection of clinically significant hepatic fibrosis (stage F2-F4) (mean area under the curve: 0.93 [95% CI: 0.85, 0.97] vs 0.91 [95% CI: 0.83, 0.96]; P = .551). Conclusion In this obese patient population, both MR elastography and VCTE had excellent diagnostic performance for assessing hepatic fibrosis; MR elastography was more

    With the rise of obesity in the American population, there has been a proportionate increase of obesity in the trauma population. The purpose of this study was to use a computed tomography-based measurement of adiposity to determine if obesity is associated with an increased burden to the health-care system in patients with orthopaedic polytrauma. A prospective comprehensive trauma database at a level-I trauma center was utilized to identify 301 patients with polytrauma who had orthopaedic injuries and intensive care unit admission from 2006 to 2011. Routine thoracoabdominal computed tomographic scans allowed for measurement of the truncal adiposity volume. The truncal three-dimensional reconstruction body mass index was calculated from the computed tomography-based volumes based on a previously validated algorithm. A truncal three-dimensional reconstruction body mass index of obese patients and ≥ 30 kg/m(2) denoted obese patients. The need for orthopaedic surgical procedure, in-hospital mortality, length of stay, hospital charges, and discharge disposition were compared between the two groups. Of the 301 patients, 21.6% were classified as obese (truncal three-dimensional reconstruction body mass index of ≥ 30 kg/m(2)). Higher truncal three-dimensional reconstruction body mass index was associated with longer hospital length of stay (p = 0.02), more days spent in the intensive care unit (p = 0.03), more frequent discharge to a long-term care facility (p obesity on patients with polytrauma. Obese patients were found to have higher total hospital charges, longer hospital stays, discharge to a continuing-care facility, and a higher rate of orthopaedic surgical intervention.

    Management of anemia in surgical oncology patients remains one of the key quality components in overall care and cost. Continued reports demonstrate the effects of hospital transfusion, which has been demonstrated to lead to a longer length of stay, more complications, and possibly worse overall oncologic outcomes. The hypothesis for this study was that a dedicated restrictive transfusion protocol in patients undergoing hepatectomy would lead to less overall blood transfusion with no increase in overall morbidity. A cohort study was performed using our prospective database from January 2000 to June 2013. September 2011 served as the separation point for the date of operation criteria because this marked the implementation of more restrictive blood transfusion guidelines. A total of 186 patients undergoing liver resection were reviewed. The restrictive blood transfusion guidelines reduced the percentage of patients that received blood from 31.0% before January 9, 2011 to 23.3% after this date (P = .03). The liver procedure that was most consistently associated with higher levels of transfusion was a right lobectomy (16%). Prior surgery and endoscopic stent were the 2 preoperative interventions associated with receiving blood. Patients who received blood before and after the restrictive period had similar predictive factors: major hepatectomies, higher intraoperative blood loss, lower preoperative hemoglobin level, older age, prior systemic chemotherapy, and lower preoperative nutritional parameters (all P blood did not have worse overall progression-free survival or overall survival. A restrictive blood transfusion protocol reduces the incidence of blood transfusions and the number of packed red blood cells transfused. Patients who require blood have similar preoperative and intraoperative factors that cannot be mitigated in oncology patients. Restrictive use of blood transfusions can reduce cost and does adversely affect patients undergoing liver resection

    To determine differences in the incidence of bronchopulmonary dysplasia (BPD) or death in extremely low birth weight infants managed on high flow nasal cannula (HFNC) vs continuous positive airway pressure (CPAP). This is a retrospective data analysis from the Alere Neonatal Database for infants born between January 2008 and July 2013, weighing ≤1000 g at birth, and received HFNC or CPAP. Baseline demographics, clinical characteristics, and neonatal outcomes were compared between the infants who received CPAP and HFNC, or HFNC ± CPAP. Multivariable regression analysis was performed to control for the variables that differ in bivariate analysis. A total of 2487 infants met the inclusion criteria (941 CPAP group, 333 HFNC group, and 1546 HFNC ± CPAP group). The primary outcome of BPD or death was significantly higher in the HFNC group (56.8%) compared with the CPAP group (50.4%, P CPAP group compared with the CPAP group (OR 1.085, 95% CI 1.035-1.137, P = .001). The number of ventilator days, postnatal steroid use, days to room air, days to initiate or reach full oral feeds, and length of hospitalization were significantly higher in the HFNC and HFNC ± CPAP groups compared with the CPAP group. In this retrospective study, use of HFNC in extremely low birth weight infants is associated with a higher risk of death or BPD, increased respiratory morbidities, delayed oral feeding, and prolonged hospitalization. A large clinical trial is needed to evaluate long-term safety and efficacy of HFNC in preterm infants. Copyright © 2016 Elsevier Inc. All rights reserved.

    To determine the efficacious cefazolin prophylactic dose for bariatric surgery using free subcutaneous concentrations accessed by microdialysis after 2 g or 3 g i.v. bolus dosing to morbidly obese women and POPPK modeling. A POPPK model with variable plasma and subcutaneous tissue protein binding was developed to simultaneously describe plasma and tissue data sets. The outcomes was predicted for common surgical site infection (SSI) bacteria over 3, 4, 5 and 6 h periods postdose, as probability of target attainment (PTA) using Monte Carlo simulation. CFZ 2 g warrant up to 5 h SSI prophylaxis for bacteria with MICs ≤1 mg/L such as Escherichia coli and Staphylococcus aureus. For species such as Klebsiella pneumoniae, which present MIC distribution frequency of 2 mg/L, the maintenance of PTA ≥ 90% occurs with a 3 g dose for surgeries lasting up to 5 h, and 2 g dose provide an adequate response up to 4 h (PTA of 89%). Effectiveness of CFZ 2 g is similar to 3 g against bacteria with a MIC up to 2 mg/L, especially if the surgery does not last for more than 4 h.

    Morbid obesity is a serious health problem associated to a significant reduction in life expectancy. To evaluate the anthropometric and metabolic changes observed in obese patients, 3, 6 and 12 months after laparoscopic Roux-en-Y gastric bypass surgery and the complications associated with the procedure. Retrospective study that included 128 consecutive obese patients submitted for bariatric surgery at the INCMNSZ (2004-2006). Their mean age was 38 +/- 10 years, 83% were women with a BMI of 48 +/- 6 Kg/m2. 65% were hypertensives, 55% had hypertriglyceridemia and 34% diabetes. A year after surgery all patients had at least reduced 20% their body weight and the percentage of excess body weight loss was 73%. The prevalence of hypertension, hypertrigliceridemia and diabetes was reduced to 24%, 17% and 12%, respectively (p < 0.001). Four patients died (3%), all of them had a leak of the anastomosis and intra-abdominal abscess. One died because pulmonary embolism, another with a myocardial infarction (after surgical reinterventions) and the other two with sepsis. Laparoscopic Roux-en-Y gastric bypass surgery in morbid obese patients favors significant reductions in body weight and associated co morbidities. This surgery is not free of complications and mortality, reason why it must be done only by surgical and interdisciplinary groups with experience in these procedures.

    Obesity in pediatric and adolescent population has reached a universal pandemic. This study aimed to summarize the literature on the longest available outcome of bariatric surgery in morbidly obese adolescents. A systematic review was conducted to pool available data on the longest available (>3 years) weight loss and comorbidity resolution outcome in adolescent bariatric surgery. A total of 14 studies reporting the result of bariatric surgery after 3 years in 950 morbidly obese adolescents were included. Preoperative age and BMI ranged from 12 to 19 years and from 26 to 91 kg/m 2 , respectively. Females were the predominant gender (72.8%). Laparoscopic roux-en-Y gastric bypass (n = 453) and adjustable gastric banding (n = 265) were the most common bariatric procedure performed. The number of patients at the latest follow-up was 677 (range from 2 to 23 years). On average, patients lost 13.3 kg/m 2 of their BMI. Among comorbidities, only diabetes mellitus resolved or improved dramatically. Of 108 readmissions, 91 led to reoperation. There was a weight regain adolescents who underwent a bariatric procedure. Although bariatric surgery is a safe and effective procedure in the treatment of adolescent morbid obesity, long-term data is scarce regarding its nutritional and developmental complication in this growing population of patients.

    2016-11-03

    The increase rates of cesarean section (CS) occurred at the same period as the dramatic increase of childhood overweight/obesity. In China, cesarean section rates have exponentially increased in the last 20 years and they now exceed World Health Organization (WHO) recommendation. Such high rates demand an understanding to the long-term consequences on child health. We aim to examine the association between CS and risk of overweight and obesity among preschool children. We recruited 9103 children from 35 kindergartens in 4 cities located in East China. Children anthropometric measurements were taken in person by trained personnel. The mode of delivery was classified as vaginal or CS, in sub-analyses we divided cesarean delivery into elective or non-elective. The mode of delivery and other parental information were self-reported by parents. Multivariate logistic regression analysis was used to examine the associations. In our cross-sectional study of 8900 preschool children aged 3-6 years, 67.3 % were born via CS, of whom 15.7 % were obese. Cesarean delivery was significantly associated with the risk of overweight [OR 1.24; (95 % CI 1.07-1.44); p = 0.003], and the risk of obesity [OR 1.29; (95 % CI 1.13-1.49); p children. After adjusted for child characteristics, parental factors and family income, the odd of overweight was 1.35 and of obesity was 1.25 in children delivered by elective CS. The associations between CS and overweight/obesity in preschool children are influenced by potential confounders. Both children delivered by elective or non-elective CS are at increased risk of overweight/obesity. Potential consequences of CS on the health of the children should be discussed among both health care professionals and childbearing women.

  15. Stress-induced alterations in estradiol sensitivity increase risk for obesity in women.

    Michopoulos, Vasiliki

    2016-11-01

    The prevalence of obesity in the United States continues to rise, increasing individual vulnerability to an array of adverse health outcomes. One factor that has been implicated causally in the increased accumulation of fat and excess food intake is the activity of the limbic-hypothalamic-pituitary-adrenal (LHPA) axis in the face of relentless stressor exposure. However, translational and clinical research continues to understudy the effects sex and gonadal hormones and LHPA axis dysfunction in the etiology of obesity even though women continue to be at greater risk than men for stress-induced disorders, including depression, emotional feeding and obesity. The current review will emphasize the need for sex-specific evaluation of the relationship between stress exposure and LHPA axis activity on individual risk for obesity by summarizing data generated by animal models currently being leveraged to determine the etiology of stress-induced alterations in feeding behavior and metabolism. There exists a clear lack of translational models that have been used to study female-specific risk. One translational model of psychosocial stress exposure that has proven fruitful in elucidating potential mechanisms by which females are at increased risk for stress-induced adverse health outcomes is that of social subordination in socially housed female macaque monkeys. Data from subordinate female monkeys suggest that increased risk for emotional eating and the development of obesity in females may be due to LHPA axis-induced changes in the behavioral and physiological sensitivity of estradiol. The lack in understanding of the mechanisms underlying these alterations necessitate the need to account for the effects of sex and gonadal hormones in the rationale, design, implementation, analysis and interpretation of results in our studies of stress axis function in obesity. Doing so may lead to the identification of novel therapeutic targets with which to combat stress-induced obesity

    Co-morbidities of vertiginous diseases have so far not been investigated systematically. Thus, it is still unclear whether the different vertigo syndromes (e.g. benign paroxysmal positional vertigo (BPPV), Meniere's disease (MD), vestibular migraine and phobic vertigo (PPV)) have also different spectrums of co-morbidities. All patients from a cohort of 131 participants were surveyed using a standardised questionnaire about the co-morbidities hypertension, diabetes mellitus, BMI (body mass index), migraine, other headache, and psychiatric diseases in general and the likelihood of a depression in particular. We noted hypertension in 29.0% of the cohort, diabetes mellitus in 6.1%, migraine in 8.4%, other headache in 32.1%, psychiatric diseases in 16.0%, overweight and obesity in 33.6% and 13.7% respectively, as well as a clinical indication for depression in 15.9%. In general, we did not detect an increased prevalence of the co-morbidities diabetes mellitus, arterial hypertension, migraine, other headache and obesity compared to the general population. There was an increased prevalence of psychiatric co-morbidity in patients with PPV, and the prevalence of hypertension was elevated in patients with MD.

    Full Text Available BACKGROUND: Studies have suggested that number of siblings and birth order is associated with obesity. However, studies combining these exposures are needed. This study aimed at investigating obesity in children and young adults in regard to different combinations of family size and birth order. METHODS: Two cohorts selected from the general population were investigated: The Copenhagen School Health Records Register (CSHRR and a Draft Board (DB sample with measured heights and weights in childhood (age 13 years and young adulthood (age 19 years, respectively. Information on birth order, number of siblings, and relevant covariates were available on 29 327 children, as well as on 323 obese young men and 575 randomly selected controls of young men representing approximately 58 000. The relation between number of siblings and birth order, respectively, and having a Body Mass Index (BMI z-score above or equal to the 95(th percentile in childhood or having a BMI of at least 31.00 kg/m(2 in young adulthood was analysed using logistic regression analyses adjusted for relevant confounders. RESULTS: Only children had significantly higher odds of obesity both in childhood and in young adulthood compared with children with siblings, odds ratio (OR =1.44 (95% Confidence Interval (CI: 1.26-1.66 and OR=1.76 (95% CI: 1.18-2.61, respectively. No association between first-born status and obesity was found. The OR of last-born children being obese was also significantly increased in childhood, e.g. OR=1.93 (95% CI: 1.09-3.43 of obesity if last-born in a family of four children. This was not found in young adulthood. Additionally, higher spacing to previous sibling (average 1872 vs. 1303 days; p=0.026 in four children families was observed in obese last-born compared to non-obese last-born children. CONCLUSION: Being an only or last-born child is associated with obesity. These associations may provide leads to targeted prevention of obesity in children.

    Epidemiological studies have reported an association between obesity and increased incidence of ocular complications including cataract, yet the underlying biochemical and molecular mechanisms remained unclear. Previously we had demonstrated accumulation of sorbitol in the lens of obese rats (WNIN/Ob) and more so in a related strain with impaired glucose tolerance (WNIN/GR-Ob). However, only a few (15-20%) WNIN/Ob and WNIN/GR-Ob rats develop cataracts spontaneously with age. To gain further insights, we investigated the susceptibility of eye lens proteins of these obese rat strains to heat- and UV-induced aggregation in vitro, lens opacification upon glucose-mediated sorbitol accumulation ex vivo, and onset and progression of cataract was followed by galactose feeding and streptozotocin (STZ) injection. The results indicated increased susceptibility toward heat- or UV-induced aggregation of lens proteins in obese animals compared to their littermate lean controls. Further, in organ culture studies glucose-induced sorbitol accumulation was found to be higher and thus the lens opacification was faster in obese animals compared to their lean littermates. Also, the onset and progression of galactose- or STZ-induced cataractogenesis was faster in obese animals compared to lean control. These results together with our previous observations suggest that obesity status could lead to hyperaccumulation of sorbitol in eye lens, predisposing them to cataract, primarily by increasing their susceptibility to environmental and/or physiological factors. Further, intralenticular sorbitol accumulation beyond a threshold level could lead to cataract in WNIN/Ob and WNIN/GR-Ob rats.

    .3 months, and 6.8 months. Conclusion: Retreatment of patients with recurrent gynecologic malignancy with Bev did not increase morbidity and was associated with treatment response. Physicians treating women with recurrent disease may consider a Bev-containing regimen even if prior regimen(s included Bev. Future studies should prospectively evaluate the efficacy of this treatment strategy. Keywords: bevacizumab, gynecologic malignancy, cumulative toxicity, treatment response

     Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and the third leading cause of cancer related death worldwide. In recent years, the prevalence of HCC has increased in both developing and developed countries. Most HCC cases develop in the presence of advanced chronic liver disease related to viral hepatitis. In particular hepatitis B virus and hepatitis C virus infections are considered as major HCC risk factors worldwide. However, current studies provide strong evidence for increasing numbers of HCC in nonalcoholic fatty liver disease (NAFLD). NAFLD represents the hepatic manifestation of metabolic syndrome which is based on obesity and insulin resistance. Epidemiologic data clearly demonstrates that NAFLD and obesity-related disorders are significant risk factors for tumor development in general and HCC in particular. As a consequence of life style changes towards higher calorie intake and less exercise, obesity and metabolic syndrome are spreading all over the world. Due to this increase in obesity and metabolic syndrome NAFLD-related HCC will become a major health care problem in the future. In conclusion, better understanding of the impact of NAFLD and obesity in the development of HCC will improve our treatment strategies of HCC and allow preventive measures.

    The study aimed to determine the relationships between the basal metabolic rate (BMR) and body composition of overweight and obese Chinese adults with type 2 diabetes mellitus (DM). This cross-sectional clinical study enrolled 193 Chinese adults with type 2 DM who were overweight (24 kg/m(2)=BMI≤28 kg/m(2), n=99), or obese (BMI ≥28 kg/m(2), n=94). Ninety-seven adults with normal BMIs, including 50 DM patients and 47 healthy adults, were recruited as a control group. BMR was measured by indirect calorimetry; predicted BMR was calculated according to the Schofield equation; and the relationships between BMR, body composition, and biochemical results were determined by the Pearson correlation. The results showed that obese DM patients had significantly higher BMRs than both overweight patients (PBMR was significantly lower than the predicted BMR (PBMR in both DM patients (r=0.874, P<0.01) and in healthy controls (r=0.902, P<0.01). It was concluded that overweight and obese Chinese adults with type 2 DM had increased BMRs compared with normal-weight controls, which may result from the difference in fat-free mass.

    Low testosterone and obesity are independent risk factors for dysfunction of the nervous system including neurodegenerative disorders such as Alzheimer's disease (AD). In this study, we investigate the independent and cooperative interactions of testosterone and diet-induced obesity on metabolic, inflammatory, and neural health indices in the central and peripheral nervous systems. Male C57B6/J mice were maintained on normal or high-fat diet under varying testosterone conditions for a four-month treatment period, after which metabolic indices were measured and RNA isolated from cerebral cortex and sciatic nerve. Cortices were used to generate mixed glial cultures, upon which embryonic cerebrocortical neurons were co-cultured for assessment of neuron survival and neurite outgrowth. Peripheral nerve damage was determined using paw-withdrawal assay, myelin sheath protein expression levels, and Na+,K+-ATPase activity levels. Our results demonstrate that detrimental effects on both metabolic (blood glucose, insulin sensitivity) and proinflammatory (cytokine expression) responses caused by diet-induced obesity are exacerbated by testosterone depletion. Mixed glial cultures generated from obese mice retain elevated cytokine expression, although low testosterone effects do not persist ex vivo. Primary neurons co-cultured with glial cultures generated from high-fat fed animals exhibit reduced survival and poorer neurite outgrowth. In addition, low testosterone and diet-induced obesity combine to increase inflammation and evidence of nerve damage in the peripheral nervous system. Testosterone and diet-induced obesity independently and cooperatively regulate neuroinflammation in central and peripheral nervous systems, which may contribute to observed impairments in neural health. Together, our findings suggest that low testosterone and obesity are interactive regulators of neuroinflammation that, in combination with adipose-derived inflammatory pathways and other factors

    OBJECTIVE: To investigate the risk of clinical affective disorders of patients who were hospitalized because of obesity in the study period 1 January 1977 to 31 December 1999. METHOD: Using data from Danish hospital registers, three study cohorts were identified by their diagnoses at discharge from...... discharged with an index diagnosis was identified. In total, 1081 events occurred in the observation period. An index diagnosis of obesity was associated with an increased risk of affective-disorders hospitalization when compared with patients with osteoarthritis (Rate ratio: 1.35 (95% CI: 1.......09-1.67)) and tended to be associated with an increased risk when compared to patients with non-toxic goiter (Rate ratio: 1.23 (95% CI: 0.99-1.53)). Patients with obesity diagnoses who did not have additional hospital diagnoses of substance- or alcohol abuse had a risk of affective disorders that was 1.55 (95% CI: 1...
