Filter by:Obesity, in addition to causing abnormal glucose and lipid metabolism, is also associated with altered plasma concentrations of multiple amino acids, including increased levels of branched-chain amino acids and decreased levels of glycine. The mechanisms and consequences of obesity- related glycine deficiency are unknown. The overall aim of this project is to comprehensively study glycine metabolic pathways in morbid obesity using stable-isotope tracer techniques in human subjects and validating kinetic findings using a cell model of oxidative stress. This will be a single-centre, observational study. 21 individuals with morbid obesity scheduled for bariatric surgery and 21 non-obese controls will be recruit. They will undergo different study visits and procedures and the human biological materials collected will be analysed for as per aims of the studies. We believe that the glycine metabolic pathways, possibly through the optimization of gluthathione (GSH) synthesis, may provide targets to develop novel therapeutic agents.
The incidence of obesity parturient has been increasing worldwide. There was a report revealing one third of pregnant women in United state considered obesity. Obesity is associated with increased in maternal and neonatal complications. Also, there was an increasing in the rate of cesarean delivery. Anesthetic management of the obese parturient is differ from non-obese parturients. There were higher risk of difficult intubation, failed intubation, pulmonary aspiration and difficult regional anesthesia such as spinal anesthesia or epidural catheter placement comparing with non-obese parturient. The aim of the study is to report complication associated with anesthesia in obese patients undergoing cesarean delivery in Single University hospital, Bangkok, THAILAND.
By World Health Organization (WHO) definition overweight (body mass index (BMI) >24.9) and obesity (BMI >29.9) are defined as abnormal or excessive fat accumulation with many possible impacts on individual's health. Association between obesity and associated metabolic syndrome (obesity, hypertension, diabetes mellitus type 2 and dyslipidemia) and oral health has become clear from several studies that proved increased odds of obese patients for developing of caries-related pathologies and periodontal disease. Periodontal disease, a major cause of tooth loss in adults, is an inflammatory disease of periodontal tissue that is initiated by dental plaque bacteria and is modulated by the inflammatory-immune host response factors. Relation between periodontal disease and obesity is bi-directional, through sharing of several proposed local and systemic pathogenesis mechanisms. For treatment of obesity, bariatric surgery (BS) procedures are methods of choice, when other less invasive options fail. They are safe, cost-effective, improve overall health and increase life expectancy. There are several types of BS interventions and most commonly performed BS is laparoscopic sleeve gastrectomy and with second most often, Roux-en-Y gastric bypass. Studies on influence of BS on periodontal health showed diverse results, with some showing no effect, while others demonstrated an increase in the prevalence of periodontitis as well as a further deterioration of periodontal tissues after BS procedure. However, studies on the prevalence of gingivitis, a reversible plaque-induced inflammation of gingiva, and its progression to periodontitis in BS patients is lacking. Furthermore, dental and periodontal status are not routinely evaluated in patients before or after BS. To the best of our knowledge studies on the effect of periodontal therapy before BS are lacking.
In response to the COVID-19 pandemic, weight management programs and metabolic surgery have been deferred to contain the virus. Quarantine and social distancing negatively impact dietary, exercise and psychological health of obese individuals. The study aims to evaluate the impact of social distancing measures on post-metabolic surgery patients compare to non-surgical obese patients and discuss potential strategies for management post COVID-19.
Direct measurements of changes in food selection in humans after RYGB have been limited by the unreliability of patients, which poses significant methodological and conceptual challenges to researchers and study design. Self-monitoring requires time and effort, and many find tracking of dietary intake tedious, which contributes to attrition. Direct measurements, however, represent an essential component in the attempt to understand how RYGB alters eating and food preferences, but laboratory settings preclude a real-life environment. The aim of this study is to investigate changes in food preferences, total energy intake of the three primary macronutrients and meal patterns between obese women (BMI ≥ 35) before and after Roux-en-Y gastric bypass and lean (BMI ≤ 25) and obese (BMI ≥ 35) controls by means of photographic food recognition with a mobile application.
In anorexia nervosa,the eating disorder (ED) is the cause of thinness. In severe obesity, the overweight is a symptom. This symptom, however, is only the consequence of possibly deregulated eating behavior. The literature, focusus a specified ED of DSM-V: Binge Eating Disorder (BED) or Binge Eating, whom estimated prevalence in the severely obese population varies from 1.4 to 49% depending on the studies. The other ED, called unspecified ED (or EDNOS for Eating Disorder Non Otherwise Specified in the English literature), are much less known. The main objective of this study is to assess the prevalence rate of unspecified ED (EDNOS or "non-BED ED") in subjects with severe obesity (BMI> 35) consulting for medical or surgical management in a General Hospital Center CSO (Specialized Obesity Center) using an adapted version of the QEWP-R, called the QEWP-RA.
Obesity is a chronic disease in which accumulation of excess body fat can result in impaired health. In cases of severe obesity, weight loss surgery can be necessary as a treatment. There are different forms of surgery but the common basic principle is to restrict food intake and decrease the absorption of food in the stomach and intestines. As a consequence, there is a higher risk of developing nutrient deficiency after surgery and supplementation of protein, vitamins, and minerals can be necessary. This study evaluates intakes of protein, vitamins, and minerals in patients with weight loss surgery and compares them to recommended intakes. Further, this study looks at the role of age, sex, and socioeconomic status in this context.
Purpose The aim of this study was to analyze the changes of microbiota among patients undergoing LSG or LRYGB on two levels of gastrointestinal tract (using oral swab and stool sample). We compared samples from patients before and after bariatric operation. Materials and methods This prospective cohort study was conducted in one academic, teaching hospital. The recommendations of the Metabolic and Bariatric Surgery Section of the Polish Surgical Society were used as indication for surgery, that is: Body Mass Index (BMI) ≥35 kg/m2 with obesity-related comorbidities or BMI ≥40 kg/m2. Analysis and endpoints Primary endpoint was to determine the difference in microbiota present in oral cavity and large intestine between patients before and after bariatric surgery. Secondary endpoint was to compare the difference in microbiota changes between patients undergoing LSG and LRYGB
The study is based on data from morbidly obese patients who fulfilled the criteria for bariatric surgery during 2016-2018 at the Department of Surgery, University Hospital Ostrava, Czech Republic.
Backround:The incidence of difficulty in laryngoscopy and endotracheal intubation is more common in obese patients. There are conflicting data on factors predicting difficult intubation. Also, these predictors are uncertain when video laryngoscopy (VL) is used. In this study we aim to investigate the correlation between airway assessment tests, anthropometric measurements and Modified Cormack-Lehane Classification (MCLC), assessed by C-MAC-D-blade VL and predictive values for intubation difficulty in class-III patients. Methods: This prospective observational study was performed in 121 obese patients (Body mass index (BMI)≥45kg/m2) undergoing bariatric surgery. BMI, modified mallampati scores (MMS), thyromental distance (TMD), sternomental distance (SMD), interincisor distance (IID), and neck, waist, and chest circumference were all recorded preoperatively. Endotracheal intubations were performed with a C-MAC D-blade VL. The glottic view and intubation difficulty were determined according to the MCLC. MCLC I-IIa was recorded as the group with no risk of a difficult intubation, the MCLC IIb-III was recorded as the group with risk of a difficult intubation and the MCLC-IV was recorded as the group with a difficult intubation. The correlation between the airway tests, anthropometric parameters and the MCLC, as well as their sensitivity and specificity in predicting the intubation difficulty based on the MCLC, were analyzed. The duration of intubation, number of attempts, external laryngeal maneuver, the equipment requirements (style, guide), and complications during intubation were recorded.
