Active clinical trials for "Weight Loss"

The proposed prospective study aims to determine whether interpretation of PSA levels in morbidly obese men require correction due to the obesity itself. If PSA levels are found to rise after weight loss, interpretation of PSA levels in morbidly obese men may be improved by upward correction of the PSA level. A 'correction factor' may be proposed for the interpretation of PSA levels in obese men, toward the clinical decision regarding indication for prostate biopsy.

The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.

The broad aim of the study is to obtain a better understanding of alterations in mesolimbic reward pathways in adiposity based on the hypothesis of a hypofunctioning reward system in obesity. This will be achieved by integrating a functional neuroimaging (fMRI) with behavioral reward tasks and the modulation of the dopamine level by dopamine depletion.

The overall goal of this study is to determine whether variations in the perilipin, and several other, genes would be a useful tool for physicians who are caring for morbidly obese patients to guide therapy. The main hypotheses to be tested is that sequence variations (polymorphisms) in the perilipin gene and several other obesity-related genes are associated with resistance to weight loss for obese individuals on energy restricted diets, potentially playing a role in the development of obesity related complications.

The aim of this study is to measure important components of weight change in patients who underwent bariatric surgery on measures of fat mass and its distribution and fat-free mass (FFM) (bone mineral density, skeletal muscle, and specific organs) at 60 months (T60) and 84 months (T84) post-surgery, and to compare compartment sizes with stable weight controls.

Researchers at Harvard Pilgrim Health Care Institute and Massachusetts General Hospital are conducting a study to learn more about how best to reach out to women (age 18-45) who are thinking about a pregnancy in the next couple of years and currently have a BMI greater than 30 kg/m2. Interested participants will be asked to complete a 15-minute survey. The survey will ask some more questions about their prior reproductive health history, opinions and experiences regarding lifestyle, weight and health. After completing the survey, researchers would like to arrange a time to complete a 20- to 30-minute semi-structured interview about their perceived health in the process of planning pregnancy.

The primary objective is to obtain stool samples from post-therapy subjects already undergoing evaluation for an H. pylori infection by upper esophagogastroduodenoscopy (EGD) and gastric biopsy.

Between January and December 2012, a total of 40 patients underwent GLP. The study will assess subject excess weight loss (%EWL) following the study procedure at 3, 6, 12, 36 and 60 months.

A study to explore the relationship between early weight loss in the 4 weeks following laparoscopic sleeve gastrectomy and outcomes, in terms of weight loss and comorbidity improvement, 7 years following the surgery.

Gastric myoelectric, inflammatory, and hormonal responses, body compositional, energy expenditure, and metabolic changes during the development of obesity and the weight loss process are underinvestigated. This project studied the myoelectrical inflammatory and hormonal responses of the stomach, in addition to energy expenditure and body composition changes during weight loss via bariatric surgery and lifestyle intervention.
