Active clinical trials for "Obesity, Morbid"

This is a research study to determine if identifying an optimal level of positive end-expiratory pressure (PEEP) targeted specifically to individualized patient characteristics will shorten the time on the ventilator. Participants will have catheter placed through the nose into the esophagus to measure the pressure inside the chest. This catheter will remain until the patient is freed from the ventilator. Participants will be randomized to usual care or to have the level of PEEP determined by the esophageal balloon pressure readings. The total time spent on the ventilator will be recorded.

Recent studies have shown that polarized training (i.e. the combination in the same session of intermittent high intensity exercise training, consisting of repeated, short-duration, high-intensity exercises on a cycle ergometer or a treadmill, and moderate exercise) can encourage the participation of obese people in body weight reduction programs, providing more dynamic exercises, less tiring and therefore more acceptable. To date, no data are available on the effects of polarized exercise in the rehabilitation of obese adolescents, who are often unwilling to engage in prolonged and monotonous motor activities. The demonstration that the polarized exercise might encourage the participation of obese adolescents in multidisciplinary body weight reduction programs, improve the cardiovascular capacity and also favor an adequate oxidation of lipids during the phase of exercise and post-exercise rest, could support its prescription in the programs of integrated metabolic rehabilitation of adolescent obesity.

The limited number of studies on the effectiveness of physical activity incentive programs for morbidly obese individuals in the literature shows the need in this area. In this study, primary aim is to investigate the effect of physical activity incentive program applied through face-to-face and whatsapp-based applications on physical activity level, functional capacity and muscular endurance in morbidly obese individuals. Secondary aim is to provide individuals with exercise habits and to ensure participants' sustainability with the physical activity incentive program planned in line with the needs of the individual.

The purpose of this study is to 1) evaluate the relationship of physical activity to quality of life and psychological functioning among adults with severe obesity (BMI>40) and 2) evaluate the effects of activity monitoring on changes in physical activity during a 6-week intervention interval.

Endoscopic sleeve gastroplasty (ESG) is a transoral endoscopic procedure that creates a tubular sleeve along the lesser curvature with a gastric volume of approximately 30%. Summarizing the available literature published since its introduction in 2013, ESG was capable to achieve > 10% of sustained total body weight loss in a majority of mildly to moderately obese patients with the caveat of only minor adverse events. Besides weight loss, little is known about the metabolic effects of ESG. The present study seeks to measure markers of glucose homeostasis during oral glucose tolerance tests before and subsequently after application of ESG in 12 patients.

Endoscopic sleeve gastroplasty (ESG) is a technique used for bariatric surgery, with results comparable to conventional surgery, in order to treat morbid obesity. It has also less risks of complications, and it is not an irreversible technique. It can be repeated overtime, regarding the evolution of the gastroplasty. There is little data in the literature on the effectiveness of endoscopic "revision". This study will assess the benefits and costs of a revision during the follow-up endoscopy.

In patients with severe obesity, bariatric surgery provides consistent and long-term weight loss. BMI ≥50kg / m2 is an independent factor of increased morbidity / mortality in bariatric surgery compared with patients weighing less than 50 kg / m2 (1.2% and 0.8%) mainly due to technical difficulties. Preoperative weight loss reduces this morbidity / mortality. Recent studies have shown that blocking blood vessels to a particular portion of the stomach (bariatric or left gastric artery embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and result in weight loss. The purpose of this study was to evaluate the safety and effectiveness of the association bariatric embolization before sleeve gastrectomy in super obese patients.

The aim of this study is to compare the paramedian approach for spinal anesthesia using ultrasound assistance (USAS) versus conventional palpation in morbidly obese patients undergoing elective surgeries.

The aim of the study is to answer a daily question in the operating room: what is the safest technique for intubation of severe/morbid obese patients (BMI 35 or more). There is a great heterogeneity of practices on the subject, so the principle is to determine a common practice to facilitate the management of these patients.

The primary objective of this trial is to assess device function and safety, with secondary objectives including the feasibility.
