Active clinical trials for "Body Weight"

The purpose of this study is to determine if a new type of mechanical ventilation, or breathing machine (called neurally adjusted ventilatory assist or NAVA), will provide additional support to infants who were born prematurely. Investigators are looking to determine if in two hours infants who weighed less than 1500 grams or 3 pounds 5 ounces, will demonstrate a decrease in the amount of carbon dioxide (the gas that humans exhale) dissolved in their blood as compared to prior to starting the study. This will be accomplished by enrolling infants who are stable on their current type of mechanical breathing that provides a constant air flow into the infant. This type of mechanical support helps keep the lungs inflated but does not help remove carbon dioxide. This study will change the type of mechanical support to a type of support called neurally adjusted ventilatory assist or NAVA. This type of mechanical support detects when the infant is breathing in by having electrical sensors on a feeding tube that is placed into the stomach through the nose or mouth. These electrical sensors detect when the diaphragm or the muscle that helps humans breath is trying to take a breath in. When the NAVA ventilator senses the attempt to breath, it provides additional air flow to make the effort of breathing easier. The ventilator will be attached to a tube or cannula that is placed into the infant's nose. After two hours of being on the NAVA ventilator a repeat measure of carbon dioxide in the blood will be performed by taking a small amount of blood from the infant's heel.

Rates of overweight and obesity are increasing, particularly among individuals aged 18 to 29. An estimated 25-35% of American college and university students are overweight or obese. Contingency Management (CM) is a behavioral intervention that provides tangible rewards for positive behaviors. CM has substantial evidence of efficacy in reducing smoking and drug use and increasing treatment retention and medication compliance. The current study will evaluate the efficacy of a 24-week CM intervention to promote weight loss in overweight and obese university students. Seventy participants with a body mass index (BMI) of 27.0-34.9 will be randomly assigned to one of two conditions: (a) LEARN, a manual guided behavioral weight loss program (Brownell, 2004), with weigh-ins and supportive counseling, or (b) LEARN with weigh-ins and supportive counseling plus CM. Participants in the CM condition will earn chances to win prizes each week in which they lose at least one pound. Once they lose 5% of baseline body weight, they will earn chances to win prizes for weight loss or weight maintenance. Additional chances can be earned by completing activities that promote weight loss. The primary outcomes will be absolute and proportional weight loss from pre- to post-treatment, as well as proportion of participants achieving clinically significant weight loss (>5% of baseline weight) and proportion moving into a lower risk BMI category. Secondary outcomes will include length of retention in the study, increase in physical activity level, and improvement in nutritional quality of diet. Effects of the CM intervention on psychiatric distress and self-efficacy and motivation to engage in activities that promote weight loss will also be assessed. We predict that participants in the CM condition will lose more weight than participants assigned to the LEARN program without CM, and that more CM participants will achieve clinically significant weight loss. We also predict that participants in the CM condition will remain in the program longer, show larger increases in physical activity, show greater improvements in diet quality, and have greater increases in levels of self-efficacy and motivation than comparison group participants. Mediators and moderators of CM outcomes will also be evaluated. If efficacious in promoting weight loss in a college population, CM could help to prevent or delay later development of obesity-related medical problems.

The goal of this project is to test whether a phone and mail-based program designed to help people who have recently lost weight helps them keep the weight off over a 2 year period.

Participants in both the existing and enhanced podcast groups will lose weight. The enhanced podcasting group will have a greater increase in weight loss, elaboration, self-efficacy, and perceived control than the existing podcast group.

Olanzapine is an atypical antipsychotic agent indicated for the treatment of schizophrenia and moderate to severe manic episode. Olanzapine is among the many antipsychotic agents associated with weight gain . The mechanism for antipsychotic drug-related weight gain is not known, although antagonism of serotonin receptors, especially the 5HT2C , and histamine receptors has been hypothesized. The purpose of this study is to observe the efficacy of a psychoeducational programme in managing the increased weight as a side effect of the olanzapine treatment. Interventions to prevent weight gain associated with olanzapine should at least include periodic monitoring and recommendations for changes in diet and physical activity. This is a phase IV, randomised, parallel study of subjects previously treated with olanzapine as antipsychotic monotherapy, which have shown an increase of B.M.I. >7% from the beginning of antipsychotic treatment (assessed during the routine visits). For the first 12 weeks of the trial approximately 60 outpatients, enrolled in one site during a period of one year, will be randomised in a 1:1 ratio into 2 treatment groups: olanzapine + psychoeducational programme or olanzapine alone. In the following 12 weeks of the study all patients undergo the psychoeducational programme. The efficacy of this programme will be assessed monitoring the mean difference from baseline to endpoint in total body weight and BMI.

Achieving independent ambulation is an important goal of hip fracture rehabilitation, as it is predictive of returning to the community and of future health problems. Current research regarding post-hip fracture rehabilitation is sparse. Body weight supported treadmill training (BWSTT) is a novel approach to retrain walking abilities. BWSTT may be ideal for retraining walking after hip fracture, as it is task-specific and alleviates the demands of maintaining balance while walking skills are trained. The use of the harness may provide a sense of security for the patient, facilitating walking training. The proposed project will investigate the feasibility and tolerability of BWSTT after hip fracture, and its impact on function, mobility, quality of life and fear of falling. It is hypothesized that BWSTT 3-5 times weekly in acute hip fracture patients will improve function, mobility, quality of life and reduce fear of falling.

The primary objective of this study is to examine the efficacy of topiramate in combination with olanzapine for the prevention of weight gain in youth with bipolar disorder. The secondary objective is to examine the tolerability of topiramate in combination with olanzapine for the prevention of weight gain in youth with bipolar disorder.

Study of whether the investigational drug CE-326,597 improves glucose control and results in body weight loss in patients with type 2 diabetes

The purpose of this study is to determine if oligofructose supplementation promotes weight loss in overweight and obese adults.

The purpose of this study is to evaluate the safety and effectiveness of fish oil supplements in maintaining weight in people with disease-related weight loss and/or cachexia.
