Filter by:The primary objective of this study is to evaluate if, in patients with severe obesity (body mass index (BMI) ≥35 kg/m2) and high-risk cardiovascular disease (CVD), bariatric surgery compared to medical weight management (MWM) safely reduces the risk of major cardiovascular events. The cost-effectiveness of bariatric surgery will also be examined. Separate sub-studies will be performed to examine the relationship between bariatric surgery and mental health, cardiac structure and function, genomics, proteomics and metabolomics.
Acanthosis nigricans (AN) is increasing in its prevalence and is the most prevalent cutaneous manifestation in individuals with obesity. Insulin resistance or hyperinsulinemia is the main pathophysiological mechanism of obesity-related AN. However, the effect of laparoscopic sleeve gastrectomy (LSG) on insulin secretion pattern in Chinese morbidly obese patients with AN is unknown. In these study, the investigators aimed to explore the insulin secretion patterns in Chinese morbidly obese patients with Acanthosis nigricans (AN) and their alterations after LSG.
This study seeks to examine the impact of bariatric surgery on oral bacteria in diabetic compared to non-diabetic patients. The purpose of this research study is to examine how diabetes changes the bacteria in the mouth. This is an important question since bacterial changes may impact oral health. Participants will attend a screening and baseline visit prior to bariatric surgery and three post bariatric surgery appointments (3 weeks post, 6 months post and 1 year to 18 months post). Samples collected at each study visit include blood, plaque, and other oral samples. At the last study visit there is an optional dental cleaning.
The purpose ot the study is to assess the effectiveness of the use of VERT on improving body image at 12 months in patients who underwent bariatric surgery in the weight stabilization phase (between 18 and 30 months after bariatric) presenting dissatisfaction with their body image compared to standard follow-up in post-bariatric surgery (lack of specific management of body image).
Obesity is likely to be the disease of the 21th century. The growth of obesity is worldwide, a pandemic, and has increased globally in the last 30 years. Developed countries were more affected, but developing countries have increasingly contributed to this epidemic as they continue to modernize. The national and global burden of obesity, with its public health and financial implications, is projected to increase markedly in the next two decades. the study aimed to assess the effect of Vit D supplementation on preventing altered levels of calcium, Vit D, and parathormone after laparoscopic sleeve gastrectomy.
Obesity, which is the second leading cause of preventable death in the world, affects all the systems in the body and affects many physiological problems, as well as the mental state, body image and quality of life of the individual. For this reason, obese individuals try various treatment methods in order to get rid of obesity, and in cases where these methods fail, they often prefer bariatric surgery. It is very important that patients who will undergo bariatric surgery can adapt to the anatomical changes in their body and shape their lifestyle accordingly. Otherwise, it is inevitable for patients to face various complications after surgery. After bariatric surgery, a structured training program in the preoperative period is of great importance in order for the patient to adapt to the changes in his body, to prevent the development of possible complications, to be affected by the negativities that may occur due to the current change, and to prepare for the new lifestyle. In this context, the main subject of this research is to enable individuals to gain healthy lifestyle behaviors by providing mobile-based training and consultancy services that enable them to easily access the right information at the desired time and place.
The objective of this study is to adapt the oxygraphy technique on human adipocytes and to characterize respiration measurements according to patients' body mass index and white adipose tissue localization (subcutaneous vs visceral).
This study is trying to determine whether the success of bariatric surgery can be predicted by evaluating the dietary sugar absorptive characteristics in the small intestine and if there is any gene expression change on the dietary sugar absorptive characteristics.
This study explores the effects of probiotic administration on the outcomes of surgical treatment, and also on the state of the intestinal microbiota and the intestinal barrier. The study protocol is designed as a randomized double-blind placebo-controlled clinical trial. Patients qualified for bariatric surgery will be randomized to receive probiotics or a placebo for 12 weeks. Researchers are going to evaluate changes in intestinal microbiota, epithelial permeability, weight loss, postoperative complications, and serum parameters reflecting inflammation, metabolic profile, and metabolic endotoxemia.
Obesity and type 2 diabetes are major causes of illness and premature death worldwide and their incidence is increasing rapidly. Bariatric surgery is considered as the "gold-standard" surgical treatment for both conditions. However, not all patients do equally well after surgery and indeed the weight loss experienced by patients undergoing bariatric surgery can vary. As such when patients are seen after bariatric surgery in clinic they fall in one of the following two categories: 1. Good responders: this is the majority of patients who lose the expected amount of weight based on the published studies. 2. Poor responders: this is a small group of patients who either lose less than the expected amount of weight after bariatric surgery or lose the expected amounts of weight early after surgery but then regain a substantial proportion of the weight they have lost. The so-called "poor responders" are exposed to all the risks of the operation and do not benefit from the weight loss as much as good responders. This study would therefore like to investigate the physiological factors that distinguish poor from good responders before, and after bariatric surgery. The study team hypothesizes that compared to good responders, poor responders exhibit: 1. a smaller degree of fullness sensation after a meal, 2. a lower energy expenditure after a meal, and 3. genetic changes (single nucleotide polymorphisms) that predispose the poor responder to development of obesity. In addition, the study team hypothesizes that poor responders exhibit: 1. lower gut hormone secretion after a meal and 2. are less sensitive to the physiological action of gut hormones compared to good responders and that this difference in gut hormone secretion and response to gut hormones prior to bariatric surgery can be helpful to predict response to bariatric surgery.
