Filter by:Background: - Being overweight may cause low-level inflammation. This inflammation may cause some of the medical problems of obesity, like high blood sugar (diabetes) and heart disease. This study will test whether a medication called colchicine can improve metabolism in adults who are overweight but have not yet developed diabetes. Objectives: - To learn whether colchicine improves sugar regulation and metabolism. Eligibility: - Healthy overweight adults18 to 100 years old. Design: - Participants must fast before each visit, including the screening visit. - Participants will be screened with blood tests,urine tests, medical history, and physical exam. They will have to drink sugar water, and have blood drawn to find out if they are healthy. - For visit 1, participants will have a medical history and physical exam and answer questions. They will have blood taken with an intravenous (IV) line, give urine sample, and give 2 stool samples.. - Also, subjects will get sugar water through one IV. Blood will be drawn from the other. This measures sugar and insulin levels. During this, participants will lie in a bed and can watch TV. - Participants will have a full-body X-ray, lying on a table while a camera passes over them. They will also have an abdominal CT scan, lying on a table that moves through a ring that takes pictures. - Participants will have a small fat tissue sample taken from their abdomen. It is like getting a mini-liposuction. - Participants will be given the study drug or placebo. They will take it twice daily for 3 months. - For visit 2, participants will have blood tests, urine tests, medical history, and physical exam. - For visit 3, participants will repeat the tests in visit 1.
Main scientific question: A previous intervention with an anti-inflammatory multifunctional dietary portfolio (MFD) showed remarkable reductions in cardiometabolic (CM) risk markers compared with a well-designed control diet. The study was performed under weight maintenance conditions in healthy subjects in a 4w crossover design (Tovar et al., 2012). MFD consumption also resulted in improved cognitive performance after 4 weeks (Nilsson et al., 2013). The present project will further study the preventive potential of MFD, using its unique properties for identification of new biomarkers and to evaluate the potential role of alterations in the gut microbiota. MFD will be tested in healthy at risk subjects in a randomized parallel design in an eight-week intervention with the test or control diet, respectively, allowing for weight loss. Assessment of standard anthropometric/biochemical markers of CM risk, metabolomics analysis and appetite regulating hormone evaluation are also planned. Associations between the gut microbiota composition and measures of CM risk are also included. The project provides unique opportunities to identify mechanisms for the metabolic impact of MFD, for further exploitation in innovative food and/or dietary concepts. Central hypothesis: The CM-preventive potential of MFD may be boosted in a medium-term trial under conditions allowing for body weight reduction. Expected additional benefits may be recorded as reduced values for conventional CM-related parameters, markers of modified gut microbiota composition and specific changes in blood metabolite profiles. Objectives: - To further improve the effect of MFD on biochemical/anthropometric CM risk markers in healthy subjects by administering the diet under conditions allowing for weight reduction. - To identify MFD-related changes in the gut microbiota associated with improved CM risk markers. - To assess MFD-related modification in metabolic pathways, studied with a metabolomics approach, and to correlate them with conventional clinical outcomes, aiming to identify new markers of altered metabolic risk.
Coleus forskohlii extract contains the bioactive compound, forskolin. Preliminary studies have shown that forskolin can increase fat metabolism thus reduce fat accumulation in both animals and humans. It has been suggested that forskolin may also suppress appetite thus reduce energy intake and results in weight loss. This study will evaluate the appetite suppressant properties of Coleus forskohlii extract. In addition the effect on central obesity and risk factors of metabolic syndrome will also be investigated.
The main objectives of this study are to test the hypotheses that: 1) consumption of beverages sweetened with sucrose will increase risk factors for cardiovascular disease to a greater extent than a naturally-sweetened fruit juice such as orange juice, and 2) chronic psychological stress may augment the adverse metabolic effects of sugar intake. The study intervention consists of 2-week's consumption of 25% of energy as sugar provided either as a sucrose-sweetened beverage or naturally-sweetened orange juice.
Metabolic syndrome (MetS) is a clustering of cardiovascular risk factors characterizing central obesity, insulin resistance, dyslipidemia and high blood pressure. The concept of MetS represents the pre-cardiovascular and pre-diabetic pathologic conditions, which has been a useful tool in prognosing the development of cardiovascular disease and diabetes mellitus. Importantly, interventions applied at the pre-pathologic stage with MetS would be of great clinical and health significance in achieving better preventive and therapeutic outcomes. Yoga, a mind-body exercise, has been suggested to have beneficial effects on dyslipidemia, hypertension and diabetes. A pilot study has demonstrated the trends in the improvement of metabolic parameters in middle-aged adults with MetS but the findings are inconclusive because of the small sample size and brief yoga follow-up period (i.e., 2-month). In addition to the needs of a better designed randomized controlled trial in studying the beneficial effect of yoga in controlling MetS in middle-aged individuals, the investigation on yoga and MetS in elderly population has been lacking. This is important as the potential use of yoga as lifestyle modification in elderly individuals with MetS will result in significant reduction of the prevalence of cardiovascular disease and diabetes. Thus, this study aims to examine the efficacy of yoga exercise in improving metabolic abnormalities in middle-aged and older adults with MetS. In addition to elderly, middle-aged adults are included in the present investigation because of the idea that cardiovascular diseases and diabetes with aging can be mostly prevented by intervention at the middle-age. A randomized controlled trial with repeated measure design will be conducted to examine the effect of 1-year regular yoga training on the MetS parameters in middle-aged and older individuals who are 30-60 and 60-80 years of age, respectively. Primary outcome measures include waist circumference, systolic/diastolic blood pressure, blood glucose, triglyceride, and lipid cholesterol profile whereas secondary outcome measures include self-reported stress and depression levels. This study is anticipated to provide valuable information in exploring the therapeutic role of yoga in managing MetS. As yoga exercise is an economical regimen which can be easily and readily applied to large scale of target population, it is of hope to be practically useful to relieve the burden on cardiovascular disease and diabetes by introducing yoga lifestyle to the management of MetS.
The aim of this study is to explore the role of Canonical β-catenin/Wnt and forkhead box O (FOXO) pathways by means of investigating their target genes in coronary artery disease (CAD) pathogenesis and to examine the effects of resveratrol (RES) on these pathways in CAD patients.
Bed rest produces insulin resistance in healthy volunteers. In this study the investigators aim to investigate the effect of 8 days bed rest on the incretin effect and how alternate daily fasting affects cognitive function and the insulin resistance produced by bed rest. The subjects will be randomized to either 3 meals a day (isocaloric diet), alternate daily fasting or one meal/day every second day (25% of daily calorie need) and four meals/day every second (175% of daily calorie need). The investigators hypothesize: 1. Bed rest reduces the incretin effect 2. Alternate daily fasting improves the cognitive function (memory and concentration) compared to isocaloric diet 3. Alternate daily fasting reduces insulin resistance produced by bed rest compared to isocaloric diet
This study aims to evaluate the effects of enterolignanas of flaxseed on nutritional and inflammatory indicators in male workers of a food industry.
Our research proposal will determine if PDE-5 inhibition exerts a favorable effect on insulin signaling pathways in skeletal muscle of subjects with impaired fasting glucose and/or impaired glucose tolerance.
This study is conducted in a cohort of HIV-positive patients on first-line anti-retroviral therapy (ART) in rural health facilities in Lesotho, Southern Africa. It examines virologic treatment failure as well as chronic communicable and non-communicable comorbidities among patients on ART. The study has two phases. Phase 1 consists of a cross-sectional survey to determine prevalence of treatment failure as well as the prevalence of the following comorbidities: diabetes mellitus, arterial hypertension, dyslipidemia, depression, alcohol use disorder, hepatitis B and hepatitis C. Phase 2 is a cohort study, where patients with treatment failure or a comorbidity or both are followed-up for 12 months.
