NCT ID: NCT03051451 Suspended - Clinical trials for Overweight and Obesity

Fixed Dose Combination of Fluoxetin and Metformin in the Management of Overweight and Obesity

Start date: n/a
Phase: Phase 2
Study type: Interventional

Clinical trial, multicenter, double-blind, placebo-controlled, comparative of three parallel groups, randomized treatment to assess the efficacy and safety using a fixed dose combination of metformin hydrochloride with fluoxetine as adjunctive treatment in patient with obesity or overweight in order to generate new knowledge and give a greater number of therapeutic options to the clinicians, one group will receive metformin 1700 mg and 40 mg of fluoxetine; Another group will receive metformin 1000 mg with 40 mg of fluoxetine, and a third group called control will receive placebo. The above described treatments will be administered according to the "Dosage Schedule" The three groups will receive tablets of physical characteristics equal to the reference drug to preserve the blinding.

NCT ID: NCT03004560 Suspended - Obesity Clinical Trials

Psychology of Minimally Invasive Surgical Scars

Start date: January 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to examine the psychological and psychosocial impact of surgical scars after minimally invasive surgery (MIS). 100 adult patients who are about to undergo bariatric procedures through the Duke Metabolic & Weight Loss Surgery program will be enrolled in this study. 50 patients will be randomly assigned to standard laparoscopic surgery and 50 will be assigned to the percutaneous group. All patients will complete pre-operative psychometric testing to establish a baseline body-image score as well as a patient's initial subjective perceptions around surgery and surgical scars. Follow-up visits will be done at standard of care timepoints - 3 weeks, 3 and 6 months, and 1 year after surgery. Subjects will complete the same psychometric measures to identify differences in psychological and psychosocial responses to standard laparoscopic and percutaneous scars. Patients will also complete a measure on scar satisfaction. The investigators hope to identify any differences between standard laparoscopic versus percutaneous approaches.

NCT ID: NCT01998815 Suspended - Obesity Clinical Trials

Role and Mechanisms of Obesity Surgery - Physical Activity and Other Predictors of Hospital Stay, Recovery and Complications After Obesity Surgery

Start date: March 1, 2015
Study type: Observational

The purpose of this study is to examine how physical activity and lifestyle factors influence postoperative recovery and postoperative complications after bariatric surgery. The hypothesis is that physically active people, with a healthy alcohol consumption and non smokers have shorter lengths of hospital stay, shorter sick-leave, fewer re-hospitalizations and fewer re-operations, fewer complications as well as a faster recovery after a surgical procedure. The investigators also hypothesize that possible risk factors for non-surgical postoperative complications e g abdominal discomfort are also life-style related factors such as smoking, high alcohol consumption, low level of physical activity, as well as other risk factors such as prior frequent abdominal pains (e g irritable bowel syndrome symptoms), high levels of anxiety and/or depression, difficulties with coping with the changed food intake regimen after obesity surgery, and generally high sensitivity for painful-sensations and nausea. First aim of this study is to investigate how life style factors prior to obesity surgery are related to hospital stay, sick-leave, immediate postoperative complication rates and the rate of resumption of QoL and normal physical function. The second aim of the study is to identify risk factors for the development of chronic abdominal discomfort and dumping symptoms after obesity surgery.

NCT ID: NCT01962857 Suspended - Obesity Clinical Trials

Effect of 4 Weeks of Shuttle Run Training on Insulin Sensitivity in Sedentary Men

Start date: October 2013
Phase: N/A
Study type: Interventional

A number of studies have shown that short duration, high intensity interval training can improve health-related outcomes, such as insulin sensitivity and cardiorespiratory fitness. However, these often use specialized equipment, such as cycle ergometers, which makes it difficult to roll these interventions out for wide-scale use in the general population. This study aims evaluate the effects of a high intensity shuttle running intervention on insulin sensitivity, fitness and related cardiometabolic risk factors in men who are currently inactive. Participants will be randomized into intervention (4 weeks of shuttle running) and control groups. We hypothesize that the shuttle running programme will result in improved insulin sensitivity, fitness and increased fat oxidation at rest compared with the control group.

NCT ID: NCT01824680 Suspended - Obesity Clinical Trials

Effect of a Physical Activity Program on the Hormonal Regulation of Food Intake

Start date: October 2012
Phase: N/A
Study type: Interventional

The primary purpose of this protocol is to assess the hormonal regulation of satiety by an intense exercise before and after a 3 month physical activity program. Hormones assessed are: leptin, grhélin, Cholecystokinin, Glucagon-Like-Peptid-1 (GLP-1), PYY. It is well known that in overweight adults and children also, an intense physical exercise diminish the food intake relatively to the total energy expenditure and this effect is persistent after a 6 weeks physical activity program. Our hypothesis are: a diminution of food intake after the intense physical exercise and a persistent diminution of food intake after the 3 month physical activity program, an augmentation of levels of GLP-1 and PYY during the intense exercise before and after the physical activity program, a diminution of the level of GLP-1 and leptin before and after the physical activity program

NCT ID: NCT01815216 Suspended - Obesity Clinical Trials

Effect of Gastric Bypass Surgery on Brain Responses

Start date: March 2013
Phase: N/A
Study type: Interventional

After obesity surgery gastric bypass (GBP) patients usually lose more than 50% of its former preponderance in relative short time (~ 2 years). But knowledge of the underlying biological mechanisms of decline in body weight is still inadequate. This project intends to examine patients' background activity in the brain (i.e. "the resting state activity") and brain volume using MRI both before and one year after surgery.

NCT ID: NCT01387126 Suspended - Obesity Clinical Trials

Effects of a High Viscosity Dietary Fibre, as Part of a Medically Supervised Weight Management Program

Start date: n/a
Phase: Phase 3
Study type: Interventional

The aim of this study is to investigate whether the supplementation of a medically supervised weight management program with a novel fibre supplement, improves body weight, body composition, and laboratory measurements in overweight and obese individuals. All subjects will participate in the medical weight management program however the intervention group will have 5 grams of a novel fibre supplemented to each meal while the control group will not.

NCT ID: NCT01351753 Suspended - Obesity Clinical Trials

Drug Therapy Induced Weight Loss to Improve Blood Vessel Function in Subjects With Obesity

Start date: March 2011
Phase: Phase 2
Study type: Interventional

Obesity is common (>30% of US adults), contributes to substantial morbidity and mortality, but is difficult to treat. Partly this is due to the transient, arduous and modest nature of lifestyle interventions. Partly it is due to the limited efficacy and safety problems of existing pharmacotherapy. Only one drug, orlistat, is approved for long-term use in obesity; but its effects on weight are relatively small. There are drugs that have been approved for other diseases but which also reduce weight. One promising approach to treating obesity is combination therapy with orlistat and one or more of these other agents. The investigators propose an innovative approach to developing new therapies for obesity coupling the use of combination therapy with rigorous assessment of cardiovascular safety. Vascular function is a quantitative surrogate clinical endpoint that has been strongly and independently linked to future cardiovascular events. Our hypothesis is that combination pharmacotherapy will reduce weight and improve vascular function in obese human subjects. The co-primary endpoints will be weight and vascular function.

NCT ID: NCT01105858 Suspended - Obesity Clinical Trials

Molecular and Clinical Profile of Diabetes Mellitus and Its Complications

Start date: April 1, 2010
Study type: Observational

Background: - Family and twin studies have suggested that genetic factors influence approximately 50 percent of a person's susceptibility to type 2 diabetes. Recently, some of the genes involved in the development of type 2 diabetes have been identified, in large part by genome-wide association studies. Certain risk factors for type 2 diabetes, such as obesity and insulin resistance, are highly inheritable, as are diabetic complications such as diabetes-related eye and kidney disorders. However, few genes associated or linked with diabetes risk factors or complications have been conclusively identified, and more research is needed to study specific genetic factors associated with these aspects of diabetes. Objectives: - To identify and characterize genetic variants associated with type 2 diabetes, its risk factors, and its complications. Eligibility: - Individuals at least 18 years of age who are not pregnant or nursing mothers at the start of the study. Design: - All participants will provide information about family history, ethnicity and ethnic background, occupation, behavioral risk factors, and other data as requested by the researchers. - In addition to a general health history, participants will provide specific information about diabetes history, with particular emphasis on date of diagnosis, symptoms, initiation of insulin therapy, complications, and current medications. - Testing procedures will be different for individuals with and without diabetes. Those without diabetes will have an oral glucose tolerance test, while those with diabetes will be examined for diabetic complications. - Other tests during the study will include the following: - Physical examination with measurements of height and weight, waist circumference, blood pressure, and other tests for individuals who have been diagnosed with diabetes - Glucose tolerance test for those who have not been classified as having diabetes - Retinal photographs - Electrocardiograms - Hepatic Ultrasound - Blood and urine tests - Depending on the results of the examination and laboratory findings, participants may be asked to return to the clinic for supplemental interviews, physical examinations, or blood tests, or to arrange referrals for medical evaluation and treatment. - Participants who have diabetes will be asked to return for yearly follow-up visits. Participants who do not have diabetes at the initial examination will be asked to return for follow-up visits every 2 years.
