Active clinical trials for "Obesity"

The primary purpose of this protocol is to assess the hormonal regulation of satiety by an intense exercise before and after a 3 month physical activity program. Hormones assessed are: leptin, grhélin, Cholecystokinin, Glucagon-Like-Peptid-1 (GLP-1), PYY. It is well known that in overweight adults and children also, an intense physical exercise diminish the food intake relatively to the total energy expenditure and this effect is persistent after a 6 weeks physical activity program. Our hypothesis are: a diminution of food intake after the intense physical exercise and a persistent diminution of food intake after the 3 month physical activity program, an augmentation of levels of GLP-1 and PYY during the intense exercise before and after the physical activity program, a diminution of the level of GLP-1 and leptin before and after the physical activity program

Many metabolic complications of obesity are a consequence of abnormal responses of the liver, muscle, and fat to insulin actions. Fenretinide may improve the effects of insulin, preventing metabolic complications.

The purpose of this study is to examine how certain factors in childhood and adolescence relate to neural vulnerabilities for obesity in young adulthood. It is hypothesized that specific individual and environmental factors will significantly predict neural vulnerabilities for obesity.

The investigators' study published in 2020 (Pekar, M. et al.: The risk of sarcopenia 24 months after bariatric surgery - assessment by dual energy X-ray absorptiometry (DEXA): a prospective study; Videosurgery Miniinv 2020; https://doi.org/10.5114/wiitm.2020.93463) shows that patients are at risk of sar-copenia after bariatric-metabolic (BM) surgery. BM surgery leads to significant changes in body composition. Significant fat loss is followed by unwanted muscle loss. The study shows that the lack of physical activity is typical for these patients. To the algorithm of postoperative care the investigators plan to include controlled exercise programs for these patients. The investigators do not know what the complexity and time required to keep patients in good condition and reduce the risk of sarcopenia is. The investigators want to find the adequate amount of physical activity while maintaining long-term compliance of these patients.

The investigators propose to conduct a randomized controlled trial with a wait-list control to determine efficacy in reducing risk of obesity and related disease in Native American employees of Twin Arrows Casino. Participants will be randomly assigned to the experimental group or the wait-list control. The experimental group will receive a 12-week mNDPR nutrition intervention with culturally relevant materials. Five NAU Masters of Public Health (MPH) students will be trained in Motivational Interviewing and the mNDPR nutrition protocol to serve as Lifestyle Coaches. These students will lead weekly, group-based coaching sessions with up to 15 participants each at Twin Arrows Casino. Participants will be assigned to their designated group based on their availability. The 12 weekly group sessions will be scheduled to accommodate various work shifts (day, night, and swing). The first group session will be 2-hours long to serve as an 'immersion', followed by weekly 1-hour sessions, all led by the Lifestyle Coaches. The Lifestyle Coaches will use Motivational Interviewing techniques to assist participants to develop personal goals. Lifestyle Coaches will also provide nutrition education, specifically using the mNDPR protocol. Participants in the wait-list control will receive the same intervention after the experimental group completes their 12-week intervention. In addition to measures at weeks 0 and 13, a 24-hour diet recall will be conducted in week 26 for the experimental group to explore long-term durability of diet quality changes.

This is a prospective collection of data from adult patients who have had an endoscopic metabolic and bariatric endoscopy procedure (EMBT) for primary or revision surgical procedures for obesity.

The objective of this study is to investigate the effect of Esomeprazol administered in tablets (Esomeprazol MUT Sandoz® 40mg) or in solution (Esomeprazol MUT Sandoz® 40mg in 10ml tap water) on acid production in the gastric pouch by measuring the intragastric pH and the serum concentration of esomeprazole.

This project will determine whether a diet culturally-adapted to Puerto Ricans can effectively decrease cardiometabolic risk for diabetes and obesity. This will help define a culturally-appropriate, feasible, and sustainable diet intervention aimed at reducing type 2 diabetes and obesity outcomes.

In this study, betaine intake will be increased in formula-fed infants through formula milk supplementation. To do this, a double-blind randomized study has been designed with the supplementation group (infant formula supplemented with betaine) and control group (unsupplemented infant formula). The main objectives of the study are to determine the safety of supplementation and to assess whether there are changes in infant growth.

Up to 60% of endometrial cancer cases are attributed to obesity, in part because obesity promotes development of atypical endometrial hyperplasia (AEH), and up to 40% of women with AEH go on to develop endometrial cancer. The increasing prevalence of obesity in premenopausal women has resulted in increasing rates of AEH in this age group. Hysterectomy with removal of the fallopian tubes and ovaries is 100% effective in preventing endometrial cancer, but this approach results in infertility. Fertility-sparing treatments exist, such as treatment with oral or intrauterine progestin, but these treatments do not work uniformly and do not combat the underlying cause of endometrial cancer, which is obesity and metabolic syndrome. Additionally, up to 41% of women on progestin eventually experience relapse of AEH or endometrial cancer. Third, many patients have insulin resistance that may worsen with progestin therapy. Thus, to improve treatment of AEH and grade 1 endometrial cancer, prevent and reverse endometrial cancer, and allow women to preserve their fertility, the investigators must integrate an effective weight loss strategy to be given with progestin treatment. It is the hypothesis that premenopausal women with endometrial hyperplasia or grade 1 endometrial cancer who desire uterine preservation will be more likely to have atypia-free uterine preservation at two years if they receive progestin in combination with a behavioral weight loss intervention versus progestin plus enhanced usual care.
