Filter by:The aim of the study is to 1) delineate the molecular mechanisms behind the large variation in insulin sensitivity among apparently healthy subjects and to 2) establish the dose-response relationship between physical training and a) metabolic health, b) appetite and c) cultural health.
Linkages between depression and cardiovascular disease have been well documented. These appear to be more than associations, and may reflect causal relationships through a number of proposed pathways, including decreased physical activity, poor dietary habits, medication non-adherence, and a direct impact on inflammatory mediators. Older adults are affected by both depression and heart disease, with increased risk in African American and Latino elderly. The BRIGHTEN-Heart trial tests the hypothesis that an enhanced primary care delivery system intervention which provides evidence-based, patient-centered mental health services targeting depression and cardiovascular risk factors can reduce the risk of development of cardiovascular disease in low-income elderly blacks and Hispanics. BRIGHTEN stands for Bridging Resources of a Geriatric Health Team via Electronic Networking, and in this intervention, specialty providers including geropsychologists, social workers, pharmacists, nutritionists, chaplains, occupational therapists, and others collaborate via the internet as a virtual team. The study will determine if such a virtual interdisciplinary clinical team collaboration can reduce depression in older (age ≥ 65) minority adults with comorbid depression and metabolic syndrome.
A series of studies are proposed to develop an intervention to increase sleep duration and study the effects on eating, exercise, and weight control. The hypothesis is that increasing sleep duration will help improve weight loss and maintenance.
The intention of the study is to evaluate the safety and potential body weight and body fat loss effects of a 12-week treatment with Zenoctil in a randomized, double-blind, placebo-controlled, parallel study conducted in Caucasian subjects. This study will also include a diet plan for each subject, calculated based on gender, age, and energy requirements; and adjusted to be slightly hypocaloric.
Background: - Metabolic syndrome is a name given to a group of factors that tend to occur together. These risk factors include central obesity (extra weight around the middle of the body) and high blood pressure and blood sugar levels. They also include low levels of HDL ("good cholesterol") and high triglyceride levels. A person is said to have metabolic syndrome if they have three or more of the above risk factors. People with metabolic syndrome are at increased risk for type 2 diabetes, stroke, and heart disease. - Cortisol, a hormone produced by the adrenal glands, is an important regulator of metabolism. People with central obesity and metabolic syndrome may have higher than normal cortisol levels that the body cannot regulate properly. Abnormal cortisol levels may play an important role in metabolic syndrome. Mifepristone is a drug that blocks cortisol. Researchers are interested in studying its effects on metabolic syndrome. Objectives: - To study the effects of short-term mifepristone treatment for metabolic syndrome. Eligibility: - Men and Women between 35 and 70 years of age are overweight or obese, and have abnormal glucose and triglyceride levels. Design: - Participants will be screened with a physical exam and medical history. They will also have blood and urine tests. - Participants will be admitted to the metabolic unit at the National Institutes of Health Clinical Center for the first 3 days of the study: - Day 1: Body measurements (height, weight, waist, hip, and neck) and blood pressure tests. Also, 24 hours of regular blood draws and 24-hour urine collection to monitor regular daily cortisol levels. - Day 2: Glucose/insulin infusion test to measure blood sugar levels. - Day 3: Infusion of cortisol-like compounds and then regular blood draws for about 3 hours to evaluate how cortisol is metabolized. - At the end of Day 3, participants will receive mifepristone or a look-alike capsule to take for 7 days at home. - After 7 days, participants will return to the metabolic unit to repeat the Day 1 and Day 2 study procedures. They will continue to take mifepristone. - One week after the second set of study tests, participants will return for a brief physical exam and blood tests. - The study procedures will be repeated after 6 to 8 weeks, with the other study drug.
Today's obesogenic environment, favors behavioral choices that lead to an excess of energy intake over expenditure, and consequently weight gain. Intervention strategies that harness the body's own appetite and satiety regulating signals could provide an effective means of countering excessive energy intake. The purpose of this study was to investigate whether a vegetable oil emulsion (Olibra) would result in weight loss that was associated with a reduction in food intake.
Orlistat is a popular drug approved for long-term use which produces weight loss by inhibiting triglycerides, main components of fats in the diet and reducing dietary fat absorption by up to 30%. The effect of this drug on human blood fatty acid profile has not been described yet. The FA composition of RBCs, plasma and platelets can be used to monitor of many pathological processes. This study presents alteration of FA composition in RBCM and phospholipids, triglycerides and cholesteryl esters from plasma of health obese female volunteers treated with nutritional orientation and orlistat (120 mg t.i.d) for 3 months.
The purpose of this study is to examine the effects of walnut consumption on endothelial function and lipid markers in overweight patients with at least one factor of metabolic syndrome as compared to the control group.
The purpose of this study is to compare a diet containing whole grains versus an energy matched diet using refined grains on body composition and metabolism.
Glucosanol™, the medical device to be investigated contains a proprietary plant extract that is a natural inhibitor of alpha-amylase and can reduce starch digestion. The rationale for this study is to confirm that Glucosanol™ ingestion will reduce body weight. A double-blind, randomized, placebo-controlled design has been chosen to assess the efficacy and safety of Glucosanol™ in subjects who are overweight and mildly obese.
