Active clinical trials for "Obesity"

Laparoscopic sleeve gastrectomy (LSG) is a surgical technique that treats morbid obesity by both restrictive and hormonal action. Consecutive patients with morbid obesity treated by LSG at our department were evaluated. Patients enrolled in the study were randomized into Group I: LSG begin the division 2 cm from the pylorus and Group II: LSG begin the division 6 cm from the pylorus. The primary outcome measure was the % of excess weight loss (%EWL); secondary outcomes included operative time, day to resume oral feeding, postoperative morbidity and mortality, improvement of comorbidity.

Study of Deep Brain Stimulation of the Third ventricle in Cluster Headache and Obesity treatment.

Several prospective trials and metaanalysis have demonstrated the superiority of bariatric surgery on the medical treatment of obesity. The Roux-en-Y Gastric ByPass (RYGBP) procedure has been practiced for more than 30 years, and is the procedure of choice for morbidly obese with metabolic disorders in most of the reference centers. Nevertheless, the RYGBP is a technically demanding procedure with a learning curve of more than 75 cases. The complication rate is around 10% in expert centers. More recently another procedure has been described which seems as efficient on weight loss and co-morbidities as the RYGBP, with the advantage of being less technically difficult and less morbid, especially for multi-complicated obese and/or the super obese. It consists of a unique gastro-jejunal anastomosis between a long gastric pouch and a jejunal Omega loop. However, this procedure could be at risk of biliary reflux and anastomotic ulcers with dysplastic changes of the gastric and esophageal mucosa. As a result, the Omega loop bypass (OLB) has only been developed by a few teams and remains a controversial subject, particularly as only one monocentric randomized trial has compared it to the RYGBP, which is remains the gold standard. The first litterature results show similar or even better weight loss efficiency than RYGBP with a better feasibility. The early complication rate seems lower, but there are still insufficient data on long term morbidity and biliary reflux consequences. By performing a randomized and prospective comparison of OLB to RYGBP, the aim of the investigators study is to analyze the weight loss efficiency, the morbidity and mortality, the feasibility, and the quality of life of both techniques, in order to validate the Omega loop bypass as a procedure of choice in bariatric surgery Hypothesis : The OLB, while being as efficient as RYGBP on weight loss and metabolic complications, could be less morbid.

To determine whether individuals who suffer from depression and obesity are able to lose weight and show improvements in mood and cardiovascular disease risk factors following 20 weeks of a combined treatment of cognitive-behavior therapy for depression and behavior modification for weight loss. Participants will be assigned to one of three treatments: 1) cognitive-behavior therapy for the treatment of depression combined with an alternative approach to weight loss, 2) a weight loss intervention combined with a depression support and education , or 3) cognitive-behavioral therapy for depression combined with a weight loss intervention.

The purpose of the study is to evaluate if supplementation with vitamin D in doses of 20.000IU per week and 40.000 IU per week will result in weight loss in obese subjects as compared to placebo during 1 year.

This trial is being conducted in pediatric patients with Hypothalamic Obesity. This generally occurs in people who have had an injury to or tumor in their hypothalamus (gland or organ that secretes hormones). The purpose of this trial is to see how an investigational treatment controls the hormone insulin by lowering the level of insulin in the body resulting in a weight loss in children who are at least 6 years of age but less than 18 years of age. Some children in this trial will receive placebo. To qualify for this study, you and your child's doctor must feel that your child's weight is inadequately controlled within a year from the time of injury to the hypothalamus or tumor of the hypothalamus. This study will help to determine if an investigational treatment is of benefit in controlling a child's weight.

The study's primary objective is to evaluate the acute and chronic (3 weeks) effects of two respiratory training protocols in obese adolescents (performed during a period of hospitalization for a body weight reduction program), with different characteristics and mechanisms of action, on GH and IGF-I secretion. The definition of the protocols is based on what has been observed by recent studies conducted on healthy people (Wuthrich et al., 2015; Schaer et al., 2018) and on patient populations in which respiratory dysfunction is a primary or secondary component of the pathology (Calcaterra et al., 2014; Pomidori et al., 2009). All planned interventions are safe and are adapted to the obese patient. Project objectives are: assessment of GH-IGF-I responses (baseline), during the first training session of the respiratory muscles conducted in the first days of hospitalization of the patients in the clinic assessment of GH-IGF-I responses (post), during the last training session of the respiratory muscles conducted at the end of the three weeks of each training session

This trial is to assess the feasibility of a larger, definitive RCT and determine the clinical effectiveness of an NHS 1:1 programme versus a modified programme with a low carbohydrate dietary intervention (as per Feinman and colleagues classification) with telehealth, physical activity and enhanced behaviour change on specified health outcomes amongst post-partum women living with obesity

Background: Obesity increasingly affects young women and contributes to increased maternal, fetal and neonatal complications. Maternal obesity contributes to the subsequent development of childhood obesity not only through social and environmental mechanisms but also through biological processes referring to the original concept of the developmental health and disease. Data suggest that management during pregnancy through nutrition counseling and adequate physical activity will help to break the familial vicious circle of obesity. To help program to be effective it is important to understand the factors that modulate participation. However, few studies have been conducted to assess the determinants that influence participation. Goal: The main objective is to analyze 15 factors that influence participation in a program combining physical activity and nutritional counseling among pregnant women with BMI ≥ 25 kg/m2. Secondary objectives are : to identify the data that influence adherence and to show that assiduous women will have a better control of weight gain and a reduction of maternal and fetal complications. to understand the biological mechanisms involved Strategy and method: A prospective research evaluating the participation in an educational program, including nutritional support and adequate physical activity, will be offered to overweight and obese pregnant women. The program will last 12 weeks, and will include three workshops on diet of the pregnant and lactating women, and the young child. Physical activity sessions will be offered once a week. Fifteen independent variables likely to influence participation will be analyzed. The association between participation and the risk of maternal and fetal pregnancy complications related to obesity will be analysed. Meanwhile, more fundamental research will be considered to determine of the biological factors involved.

New studies are revealing how a high-fat diet could be making the cells of the intestinal lining more likely to become cancerous. The investigators would like to study how obesity influences growth of intestinal stem cells, which could then trigger intestinal tumors. The investigators are proposing a Pilot Study of 20 subjects (comprised of 10 participants from each of two different BMI categories: 20-25 and 35 & above), who will be asked to provide blood, stool, & urine samples, undergo a flexible sigmoidoscopy, and complete food frequency questionnaires
