Filter by:The purpose of this study is to describe change in body weight in non-diabetic morbidly obese patients after laparoscopic adjustable gastric banding (LAGB) with twice daily exenatide or placebo injections.
A collaborative research project with Dr. Kathleen Keef (Department of Physiology, University of Nevada School of Medicine, Reno, Nevada) studying the role of putative neurotransmitters in human intestine.
The study aims to investigate the long term results of a randomized clinical single-centre trial comparing two standard operative techniques in bariatric surgery; laparoscopic adjustable gastric banding and vertical banded gastroplasty.
The relation between obesity and ischemic heart disease (IHD) is under considerable debate. The reduction in all-cause mortality and, more specifically, the reduction in cardiac-related mortality seen after weight-loss surgery, may be due to regression or slowing developement of subclinical IHD. Function of cells lining the arteries (endothelium) is closely related to the state of IHD and its measurement can serve as a surrogate marker for the existence and severity of IHD. The investigators hypothesize that the prevalence of undiagnosed IHD in the morbidly obese population is high and that following surgery for weight reduction there is a halt in the progression, or even a regression in its severity. The study includes measurement of endothelial function before and after weight-reducing surgery.
The purpose of this study is to look at certain areas of the brain that are related to addictive behaviors, such as overeating. These areas are called 'dopamine type 2 receptors' (DRD2) and other studies have shown that obese people have less of these. We propose that low DRD2 availability seen in morbidly obese subjects will change with weight loss associated with bariatric surgery.
This study compares if there is any difference doing antrectomy while performing a sleeve gastrectomy for treating morbid obesity. The investigators compare the differences between leaving or not leaving the antrum in terms of food tolerance, weight lost and quality of life.
Bariatric surgery in the treatment of morbid obesity is associated with long-term weight-loss and decreased overall mortality. Long-term results have been reported for laparoscopic gastric bypass procedures but the long-term results of laparoscopic sleeve gastrectomy are yet unavailable. As sleeve gastrectomy is a rapid and less traumatic procedure with good short-term results of weight loss and resolution of comorbidities, the investigators initiated a prospective randomized two-center study comparing laparoscopic sleeve gastrectomy (LSG)with laparoscopic gastric bypass (LGB) in the treatment of morbid obesity. Study hypothesis: As sleeve gastrectomy is less traumatic, easier and faster to perform compared with gastric bypass,LSG could become the procedure of choice to treat morbid obesity if the long-term results of weight loss and resolution of comorbidities are comparable with laparoscopic gastric bypass.
This study has two phases: 1. In phase 1 of the study (8 weeks),the effect of two different low calorie diets on manifestations of PCOS, including risk factors for the metabolic syndrome and cardiovascular risk profile will be compared. 2. In phase 2 the long term effect (next 44 weeks) on sustained weight-loss and the above mentioned parameters will be compared and evaluated.
Very little information is available about extremely obese (body mass index [BMI] > 40 kg/m2) adolescents. The purpose of the Follow up of Adolescent Bariatric Surgery (FABS) study is to collect information obtained during the clinical care of obese adolescents from all over the country that can be used by researchers to study obesity, the complications of obesity, and the outcomes of obesity treatment during adolescence. This information will be used to describe the experience of the obese adolescent, including how obesity during adolescence and its treatment impacts health and well-being. The information may also be used to study causes of obesity, to determine the predictors of successful obesity treatment and for other obesity related research. Because of the importance of understanding the outcome of obesity and obesity treatments (surgical and non-surgical) on the patient over time, the data included in the study will be collected before, during and after any treatments rendered. For those who do not undergo a treatment which results in major weight change, it will be critical to determine the natural history of adolescent severe obesity as the adolescent transitions into adulthood. Finally, another important purpose of the FABS research study is to obtain patients' consent to be contacted for possible participation in future research studies. SPECIFIC AIMS: 1. To describe the natural history of morbid obesity among adolescents who seek treatment for their obesity 2. To describe major outcomes following bariatric surgery in adolescents evaluated at 3, 6, 12, and annually for 10 years post-operatively and compare these to outcomes to patients managed non-surgically 3. To organize a national cohort of severely obese adolescents who agree to be contacted in the future for research studies
Inflammation in the adipose (fat) tissue is an important condition leading to metabolic derangements and cardiovascular disease in obese patients. n-3 polyunsaturated fatty acids exert anti-inflammatory effects and prevent adipose tissue inflammation in rodent obesity. This study tests the hypothesis that n-3 polyunsaturated fatty acids ameliorate adipose tissue inflammation in morbidly obese patients.
