Active clinical trials for "Obesity"

Morbid obesity is an increasing medical problem in the western countries. It's related to comorbidities as diabetes mellitus, hypertension, OSAS, arthrosis and hypercholesterolemia. The Roux-en-Y Gastric Bypass (RYGB) is an effective surgical therapy for morbidly obese patients. A part of these patients will have disappointing results, and have weight regain on the long term. Some studies show more weight reduction by increasing the biliopancreatic limb in patients with morbid obesity. The objective of this study is to investigate the effect of variations in the length of biliopancreatic limb on weight reduction in morbidly obese patients undergoing RYGB-surgery. We hypothesize that longer biliopancreatic limb results in more weight reduction. The study design is a prospective, randomized control trial. The patients will be randomized in 2 groups: a standard RYGB (short biliopancreatic limb) and long biliopancreatic limb RYGB.

The purpose of this study is to provide initial clinical data to support the feasibility of use of the ValenTx Endo Bypass system in enhancing weight loss and co-morbidity resolution in morbidly obese subjects

Adequate postoperative analgesia can facilitate recovery following gastric bypass surgery for morbid obesity. The efficacy and safety of intravenous patient - controlled analgesia has been studied, but up to date no data are available concerning the use of thoracic epidural patient-controlled analgesia regarding the use of levobupivacaine combined with morphine in morbidly obese patients. The investigators' aim in this prospective, randomized, double-blinded study was to compare the analgesic effectiveness, the dose requirements and side effects of thoracic epidural patient controlled analgesia 0.1% and 0.2% levobupivacaine combined with a continuous epidural administration of morphine, with or without a loading dose, after open gastric bypass for morbid obesity.

The purpose of this investigation is to conduct an 8-week pilot study to examine the effects of two different leisure-time activity prescriptions on dietary intake, leisure-time activities, and weight loss in 30 adults receiving an 8-week behavioral weight loss intervention.

The Articulating Circular Endoscopic (ACE) Stapler is an investigational system using endoscopic guidance to trans-orally place plications in the stomach in obese subjects to reduce volume and expansion of the fundus and greater curve to abate hunger as part of a supervised weight reduction program. The primary objective of this study is to perform an evaluation of the safety of the plication procedure. The secondary objective of this study is to evaluate the preliminary efficacy of the ACE Stapler for the treatment of obesity over a 24 month follow-up period.

Bariatric surgery is the most effective treatment for morbid obesity. Roux-en-Y gastric bypass (RYGB) is a bariatric procedure with known safety and effectiveness. Laparoscopic sleeve gastrectomy (LSG) is a newer procedure gaining popularity. The aim of the study is to compare outcomes of these two surgical methods in terms of weight loss, improvement of common comorbidities of obesity and influence on metabolic and hormonal status.

To examine if 3 months of treatment with a GLP-1 (glucagon-like-peptide-1) analogue can induce weight loss in obese, non-diabetic patients with a diagnosis within the schizophrenic spectrum. The investigators will also examine possible associations between GLP-1 treatment and peripheral metabolic parameters such as change in body fat and HbA1c. Moreover, the GLP-1 analogue treatment will be associated with the effects/changes on cognition and subjective quality of life. Possible cerebral effects (pro-cognitive) of the GLP-1 analogue treatment will associated and correlated with changes in the brain, functional magnetic resonance imaging (fMRI).

Obesity is perhaps the most urgent public health crisis in pediatrics. Thus, managing childhood obesity is a top priority among pediatricians in primary care settings. However, effective treatment typically is multidisciplinary, and most practices currently do not have the infrastructure for coordinating integrated care. With the advent of the Affordable Care Act (ACA), innovative systems for building multidisciplinary teams to provide integrated care through a patient-centered medical home will be at a strategic advantage. The use of electronic technologies for delivering health-related information or services, known as telehealth, is an innovation with the potential to streamline integrated care and transform interventions for chronic diseases. We propose a pilot study to evaluate telehealth for treating pediatric obesity in collaboration with a community practice (Wareham Pediatrics). Patients aged 10 to 17 years who participate in the telehealth intervention study (N=40) will be randomly assigned to an "immediate" intervention group or a "wait list" control group. Subjects in the "immediate" intervention group will begin the 6-month telehealth intervention at the time of enrollment in the study and then receive general patient/family counseling from their primary care providers (PCPs) at routine office visits during a 6-month follow-up period. Those in the "wait list" control group will receive general patient/family counseling from their PCPs for 6 months followed by the telehealth intervention for 6 months. Thus, the total duration of participation in the study for each subject will be 12 months. The telehealth intervention will include dietary, physical activity, and behavioral management counseling provided by videoconferencing from the OWL clinical providers at Boston Children's Hospital to children in their homes, or at a telehealth station at Wareham Pediatrics.

Obese patients have an increased risk for developing severe metabolic disorders. This risk can only partly be reduced by weight reduction. The investigators have in a pilot study investigated if removal of abdominal fat (visceral) in addition to weight loss has additional beneficial effects on the metabolic profile and weight loss. This study aims to further investigate if removal of abdominal fat (major omentum) leads to beneficial metabolic effects.

The purpose of this research study is to see whether wearing a weighted vest during a period of active weight loss can decrease the loss of muscle and bone that occurs during weight loss. We will also determine if study participants who wear the weighted vest will have greater improvements in physical function and self-reported disability, pain, stiffness, fatigue and quality of life. This knowledge could impact weight loss programs designed for older adults. Hypothesis: Participants randomized to VEST will experience similar weight loss, but less loss of lean mass and bone density, than participants randomized to Control.
