Active clinical trials for "Obesity, Morbid"

ACHT - Adipositas Care and Health Therapy - is a structured, digitally-supported, cross-sectoral and close to home program developed for the postoperative care of patients following obesity surgery. The aim is to ensure the long-term success of therapy following bariatric surgery. ACHT was selected by the Federal Joint Commission for support under the Innovation Fund. The project started in July 2019 and will end in December 2022.

Study is designed to screen psychological cognitive baseline and retention/improvement after weight loss surgery.

The aim of the present study is to identify new obesity-related genetic defects and determine their association with clinical manifestations in families with childhood-onset severe obesity. The investigators hypothesize that by exploring children with severe early-onset obesity they can find new obesity-related genetic defects and by exploring obesity-associated clinical manifestations the investigators can elucidate the outcomes of severe childhood obesity.

Laparoscopic sleeve gastrectomy (LSG) is currently the most frequent primary bariatric procedure performed worldwide. LSG is a safe and effective technique in terms of excess weight loss and it is, moreover, a powerful metabolic operation that activates significant hormonal pathways that lead to changes in eating behavior, glycemic control and intestinal functions.Regarding a technical point of view, LSG might be considered a time saving procedure for the absence of intestinal anastomosis. The most frequent and sometimes dangerous complications are leaking, hemorrhage, splenic injury, stenosis and Gastro-Esophageal Reflux Disease (GERD). Despite its established efficacy and safety, dispute still exists on the optimal conduction of LSG operative technique: bougie size, distance of resection margin from the pylorus, the shape of section at the gastroesophageal junction, staple line reinforcement and intraoperative leak testing are among the most controversial issues . Thus, the primary aim of the present retrospective multicentric study is to evaluate intra and peri-operatory (< 30 days) and post-operative (> 30 days) morbidity and mortality rates of patients undergone LSG, and the correlation of the latter rates with different surgical measures. Secondary aim is to evaluate the strategy for the treatment of the complication, and if there is a correlation between morbidity/mortality and volume of the Bariatric Center

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.

About 380 million children and adolescents suffer from overweight and obesity at the global level. Obesity results from the interplay between biological (sex, age, fetal programming, gut microbiota, epigenetics, and genetics) and environmental factors (e.g., unhealthy diet, physical inactivity, stress). Mutations in genes from leptin melanocortin pathway are involved in "non syndromic monogenic obesity", characterized by severe early onset obesity, hyperphagia and endocrine deficiencies. Exact frequencies of mutation in these genes are not precisely evaluated in french children with severe obesity. Moreover new treatment, such seltmelanotide are avalaible in case of certain mutation, leading to a significative weight loss in treated patients.

Obesity has become an important medical and social problem in western countries today. Roux-en-Y gastric bypass (LRYGB) is the most commonly performed surgery for the treatment of morbid obesity in the United States. Recently, there has been a steady increase in the number of surgeons performing bariatric surgery. In 2008, approximately 344,000 bariatric procedures were performed worldwide, of which 220,000 were performed in the United States and Canada. Most of these surgeries were laparoscopic gastric bypass procedures. There are many technical variations in the performance of the Roux-en-Y gastric bypass, especially when the approach is laparoscopic. Three techniques are commonly used when creating a gastrojejunostomy (GJ): hand-sewn, linear-staple, and circular-staple approaches. The effect of larger-caliber gastrojejunostomy on long-term weight loss is worrisome. Numerous recent reports describe the relationship between gastrojejunostomy enlargement and weight gain after gastric bypass, suggesting that this is a potentially valid concern. In this study, we aim to determine the effect of this potential GJ enlargement on weight loss.

The purpose of this study is to better understand the impact of weight-loss surgery on telomere length. Telomeres are a key marker of biological aging of cells. Telomere shortening is a natural process of aging. Several pathologies and lifestyles are associated with premature telomere shortening, such as obesity, diabetes mellitus or sedentary lifestyle. New evidence supports that telomere shortening can be partially reversed by lifestyle changes such as healthy diet, reduced stress, or increased physical activity.

The management of obesity is based on a multidisciplinary approach and justifies the use of surgery in patients with the most severe forms. Surgery for obesity or bariatric surgery generally allows rapid and significant weight loss however it is associated with significant risks, and its long-term results remain heterogeneous and unpredictable. Long-term data will clarify the role of different types of bariatric surgery in surgical strategy, improve patient information and identify predictors of failure in order to provide personalised and tailored surgery for each candidate .

The study consists in determine the transpulmonary pressure in morbidly obesity patients that require mechanical ventilation. both gender only adults Medical intensive care patients.
