Active clinical trials for "Obesity"

The overall purpose of this project is to study the acute, short- (≤ 1 year) and long- (> 1 year) term effects on body composition and psychological health after a 10 to 14-weeks comprehensive lifestyle modification program for the treatment of severe obesity. The aims of the PhD project are to investigate whether an intensive lifestyle intervention leads to acute and short term (< 1 year) changes in: The BMI/Weight Body composition (waist circumference, fat mass, fat free mass, skeletal muscle mass and visceral fat area) Psychosocial factors such as eating behavior, anxiety and depression symptoms and health-related quality of life

Gastric restriction is an important principle of both roux-en-Y gastric bypass and laparoscopic adjustable gastric banding. The FDA cleared OverStitch Endoscopic Suturing System (Apollo Endosurgery, Austin, TX) offers the physician the ability to restrict gastric size by approximating tissue endoluminally via an incisionless/per-oral approach. The use of this system has the potential to reduce the complications associated with current surgical approaches while effecting the desired gastric restriction. The primary objective is to collect data on the use of the OverStitch Endoscopic Suturing System (Apollo Endosurgery, Inc. Austin, Texas) for gastric tissue approximation during primary gastric restrictive procedures.

Venous thromboembolism (VTE), deep vein thrombosis (DVT) or pulmonary embolism (PE) is a common medical condition encountered during hospitalization in a medical environment. The use of thromboprophylaxis with Low Molecular Weight Heparin (LMWH) or fondaparinux has reduced more than 50% relative risk of thromboembolic complications.However, while obesity defined by a body mass index (BMI) greater than 30 kg/m2, is a major risk factor for venous thrombotic events, data on obese patients are limited. In fact, less than 20% of patients included in the three major studies of preventive medicine had a BMI ≥ 30 kg/m2 and most studies specific to the obese population comes from a series of bariatric surgery patients or orthopedic surgery. The main results of this series show regarding the obese population a decrease of the anti-Xa activity during the administration of a standard dose of enoxaparin (40 mg / d). However, no specific recommendation in this population has not been published to date and therefore,the dosages currently used are the same regardless of the patient's weight. In this context, the use in obese patients hospitalized in a medical environment a stronger dosage of enoxaparin (60 mg / d) compared to the standard dose of 40 mg / day, could get rates anti-Xa activity levels more consistent with the treatment required, and thus reduce the risk for thromboembolic complications in these patients

The purpose of this study is to determine if the herb, Glucomannan, is an effective non-pharmacological appetite suppressant for overweight or Class I obese patients. The study design will not include any other lifestyle changes which enhance weight loss in order to completely isolate the effects of Glucomannan as a non-pharmacological appetite suppressant.

The purpose of this study is to help find out more about how the Primary Obesity Surgery Endoluminal (POSE) procedure makes patients feel less hungry and fuller faster, leading to weight loss. In this study, USGI Medical wants to see if stomach emptying and gastro-intestinal hormone levels change after a POSE procedure with an increased (as compared to typical) number of anchors placed.

Obesity has been shown to be resistant to treatment in adults, adolescents, and in school age children, but not during early childhood. Yet knowledge on the effectiveness of early childhood treatment programs for obesity is still very limited, preventing the widespread implementation of such programs. The overarching purpose of this study is to evaluate the effectiveness of early treatment of childhood obesity. The investigators plan to perform a carefully-designed randomized controlled trial that will evaluate different treatment options offered to families with children with obesity, organized within the healthcare system and followed up for at least 1 year post-baseline. Participants will be children aged 4-6 years (N=180) with obesity and their parents. This study will facilitate a close examination of key treatment components and mechanisms of change. Results from this study will lead to better healthcare options for obesity treatment during childhood and ultimately to the prevention of obesity later in life from a public health perspective.

The purpose of this study is to determine the impact of primary care referrals to community physical activity programs for overweight and obese youth aged 6-18 years on objectively measured physical activity and cardiorespiratory fitness, as well as other cardiovascular health indicators. We hypothesize that physical activity referrals will result in higher levels of physical activity and fitness.

Objective: It is unclear whether prolonged electrical muscle stimulation can improve cardiorespiratory fitness and reduce body fat in obese subjects. The purpose of this study is to investigate the effect of prolonged combined thermal and electrical muscle stimulation (cTEMS) on peak oxygen consumption (VO2 peak) and body composition. We will also investigate the biochemical effects and the resultant lipolysis-related gene expression changes in adipocytes. Methods:Eleven obese (BMI≥30) individuals will receive cTEMS in three 60-minute sessions per week for 8 weeks. Activity levels and dietary habits will be kept unchanged and controlled with an accelerometer and nutritional questionnaire. Before and after the stimulation period, functional capacity are assessed by VO2 peak, and body composition was assessed by dual-energy X-ray absorptiometry and bioelectrical impedance analyses. Lipolytic activity will be determined in abdominal adipose tissue by 24 hours of microdialysis on a sedentary day, and adipose tissue biopsies will be taken for the gene expression analysis.

The objective of this study was to test the efficacy of a partial meal replacement added with vitamins, minerals and inulin on weight reduction, blood lipids and micronutrients intake in obese Mexican women

The purpose of the study is comparatively analyze the advantages and disadvantages of banded versus unbanded laparoscopic Roux-en-Y gastric bypass (RYGB). The outcome variables of the general study included morbidity, maximal weight loss, and late weight regain.
