Filter by:To demonstrate the effectiveness of an easily administered intervention (guided self help) aimed at reducing binge eating in patients undergoing bariatric surgery. The investigators hypothesize that patients who have guided self help pre-operatively will have reduced episodes of bingeing pre-operatively compared to those having treatment as usual (bariatric surgery), which will be maintained in the post-operative period, and will be associated with improved weight loss and psychological outcomes after surgery.
Approximately one billion people suffer from hypertension worldwide. At least 10% of this population, that is, 100 million people, also suffers from associated chronic conditions namely, atrial fibrillation (AF), obesity, arterial stiffness (AS), and heart failure (HF). Personal interaction with medical practitioners (doctors) and review of published clinical research confirms that current non-invasive automatic blood pressure (BP) monitors that rely on BP pulse analysis alone cannot provide accurate measurement due to the unpredictable/weak nature of BP pulses in the above-mentioned chronic conditions. Lack of accuracy in BP estimation can lead to wrong diagnoses and hence to complications such as stokes and heart attacks. The Sponsor is developing a novel non-invasive BP monitor that is similar to existing automatic monitors yet is capable of acquiring and analyzing electrocardiogram (ECG) data in conjunction with BP pulse data to provide better and more accurate measurements in the above chronic conditions. The objective of this clinical trial is to evaluate the performance of this ECG-assisted BP monitor against invasive BP measurements in a small group of patients who suffer from the above conditions.
The purpose of this study is to determine the efficacy and safety of topiramate (96 mg or 192 mg daily) as compared to placebo in maintaining weight loss in obese subjects who participated in an eight week intensive non-pharmacologic weight loss program. The primary efficacy endpoint will be the percent change in body weight from enrollment visit to week 60.
Hypothesis 1: A quantifiable difference in inflammatory cytokines exist in women with burn injury and this correlates with clinical markers of outcome Hypothesis 2: The amount of adipose tissue contributes to the severity of cellular immune response (CMI) dysregulation in response to burn injury Skin-fold caliper measurements will be taken on consented patients (both male and female) to determine body fat percentage. Serum samples will be obtained from these patients. The level of inflammatory cytokines in the serum will be measured to determine if there is a link between body fat percentage, pro-inflammatory cytokines and the ability of women to survive burn injury.
Investigate whether the course of an isolated nocturnal alveolar hypoventilation can predict the future occurrence of obesity-hypoventilation syndrome (OHS) in obese subjects
Few obesity prevention programs have produced weight gain prevention effects that persist over long-term follow-up and those that have are extremely lengthy, averaging 52 hr in duration, making implementation difficult and costly. The 2010 US Preventative Services Task Force (USPSTF) recommendations for treating child & adolescent obesity state that programs should have ≥ 25 hr of comprehensive treatment including dietary, physical activity and behavioral counseling, and that programs with < 25 hr usually do not produce improvements. The implication is that, if centers cannot provide this level of service (as most cannot), it is not worth providing any kind of treatment at all. In extreme exception to this, an intensive 3-hr non-restrictive obesity prevention program involving participant-driven healthy lifestyle improvement plans designed to bring caloric intake and output into balance (Healthy Weight) has been found to significantly reduce increases in BMI and obesity onset relative to alternative interventions and assessment-only controls through 3-yr follow-up. We propose to test an extended 6-hr version of the Healthy Weight intervention in a sample of primarily low SES, minority adolescents and young adults who are overweight and report body dissatisfaction and subthreshold eating disorder symptoms, as these are prevalent risk factors for obesity. We will test the hypothesis that participants assigned to the Healthy Weight vs. control intervention will have significantly lower BMI and % body fat during follow-up. Secondary outcomes will include body dissatisfaction, depressive symptoms, and eating disorder symptoms. 300 adolescents and young adults at high risk for future weight gain by virtue of their age, BMI percentile, body dissatisfaction and eating disorder symptomatology will be randomized to Healthy Weight or weight control educational video. Participants will complete assessments of BMI, body composition, potential mediators, and other outcomes at pretest, posttest and 6--mo follow-ups (in yr 1). Thus, to refute the USPSTF recommendations statement, we propose to show that a 6-hr intervention led by graduate students can produce significant reductions in risk for both obesity and eating disorders, suggesting this inexpensive and brief intervention could and should be rolled out nationwide. Primary Aim: To test the hypothesis that Healthy Weight will significantly reduce increases in BMI, % body fat, and risk for onset of obesity during follow-up. Secondary Aim: To test the hypothesis that Healthy Weight will significantly reduce body dissatisfaction, depressive symptoms, and eating disorder symptoms.

This is an open-label trial investigating the effect of Spatz 3 intragastric balloon on weight loss on obesity and associated co- morbidities. The study aim is to evaluate the effect of the intra gastric balloon on weight reduction and on related co- morbidities during 1 year of balloon implantation and a year following explantation.
The purpose of the study is to test the effects of blocking sympathetic nerve activity with a drug called clonidine on blood vessel function and muscle nerve activity in adults who are obese and have high blood pressure. The cohort of subjects will consist of 69 healthy young men and women age 18-79 years who are obese, defined as a body mass index > or = to 30 kg/m2, who have untreated systolic hypertension (systolic blood pressure > or = to 130 - <180 mmHg- average of at least 3 measurements 2 min apart after 10 min seated resting position). These 69 subjects will then be randomized to 3 treatment arms: clonidine (0.1 mg/day), hydrochlorothiazide (25 mg/day) or placebo for 4 weeks in years 1 and 2. All tablets will be encapsulated by to look identical. Subjects will randomly (1:1:1) receive one of the following combinations in a double-blind, placebo-controlled design: 1. Oral clonidine (0.1 mg twice/day) 2. Oral hydrochlorothiazide (12.5 mg twice/day) 3. Oral placebo I
Brown adipose (fat) tissue (BAT) is a type of fat tissue found in certain small rodents and human babies that is capable of extremely high rates of energy burning. We now know that in adult humans it is present and also able to burn energy. In addition to increased energy expenditure during cold exposure, energy burning is also increased after consuming a meal. Animal studies have shown that part of this additional energy consumption is contributed by BAT. In the present study we will aim to examine whether BAT activity is increased after a meal.
This is an observational study to characterize the prevalence of Obesity Hypoventilation Syndrome in patients referred to the sleep lab.
