Filter by:The objective of the proposed study is to design and evaluate a touch screen computer based multi-factorial intervention to educate individuals at risk of Metabolic syndrome in diverse Indian settings including urban, rural and slum in the State of Bhubaneshwar. The study objective is to improve metabolic syndrome related knowledge, attitude and practices among individuals using the proposed interactive, bilingual computer based educational program.
Psoriasis is associated with increases in markers of inflammation in the skin and blood and increasingly is thought to be a systemic inflammatory disease and risk factor for incident diabetes mellitus, myocardial infarction, stroke, and premature cardiovascular death. Furthermore, it is important for clinicians to be aware that psoriasis can have a substantial emotional impact on an individual, which is not necessarily related to the extent of skin disease. FDG-PET/CT represents an innovative approach to studying systemic inflammation in a manner that is sensitive, quantifiable, and anatomically localizable. Also, recent study show that chronic disease such as end stage renal disease with depressive symptoms have decreased cerebral glucose metabolism in several brain areas in F-18-FDG PET/CT. So this protocol was designed to evaluate usefulness of PET/CT to detect systemic inflammation and abnormality of cerebral glucose metabolism and association with metabolic syndrome/major depressive symptoms in patients with psoriasis.
This project will examine whether short-term (over a 12-hour period) pharmacological lowering of the stress hormone 'cortisol' improves the nervous system response to food intake in overweight or obese individuals who have metabolic syndrome. The investigators know from our previous research that overweight/obese persons who are insulin resistant, have a blunted sympathetic nervous response to carbohydrate ingestion. This means that they are less able to dissipate energy from caloric intake, which would favour the maintenance of the obese state. Cortisol adversely impacts on insulin action and transport into the brain and cortisol levels are often elevated in persons with central (abdominal) obesity. A randomized, double-blind, placebo controlled, cross-over design will be used to compare the effects of overnight treatment with metyrapone (15 mg/kg at midnight and 15 mg/kg at 6 am) versus placebo on sympathetic nervous system activity in response to a standard 75-g oral sugar (glucose) tolerance test. A 2 week washout will separate treatments. Metyrapone is a drug that reversibly inhibits the enzyme 11beta-hydroxylase, and therefore the production of cortisol. It is used clinically to test the activity of the adrenal gland (the key site of cortisol production) and the pituitary gland. The investigators anticipate that at the dosage used, it will lower blood cortisol concentration by 44 to 64% during the experimental morning. The study protocol comprises two screening visits and two experimental mornings. Key procedures will include: - Assessment of insulin action (sensitivity) using the gold standard 'clamp' method. - Measurement of sympathetic nervous system activity by both biochemical methods (isotope dilution which provides a measure of the apparent rate of release of 'noradrenaline'-the key neurotransmitter in the sympathetic nervous system) and direct intra-neuronal nerve recordings from the peroneal nerve in the lower leg. - Indirect calorimetry to assess resting metabolic rate and the response to sugar ingestion. - DEXA scan to quantify fat and lean mass. - Assessment of arterial elasticity and calf blood flow by non-invasive methods. - A standard 75g oral sugar tolerance test. The results will provide important new information regarding the role of cortisol on nervous system function in overweight/obese individuals.
The purpose of this study is determine the incidence of metabolic syndrome (MetS) in people of high risk, of 40 or more years and attended in the Primary Care. Evaluating the association between anxiety, depression, quality of life and the vital stressful events, and the development of the metabolic syndrome in general population. Our hypothesis is that population of the cohort with bigger degree of stress will develop earlier the metabolic syndrome. If our hypothesis about the metabolic syndrome are demonstrated, it would allow establishing in a future interventions on these factors of risk to prevent or to decrease the incidence of this syndrome in the Primary Care.
The aim of this study is to determine the prevalence of metabolic syndrome amongst obese children in our region with a body mass index (BMI) above the 95th percentile for age and sex.
Although it is frequently mentioned in the media that overweight and obesity have reached epidemic proportions worldwide and in this country, some Canadians are perplexed and sometimes confused about the role of obesity in diabetes and heart disease. In fact, the investigators even hear from time to time that there could be "healthy" obese individuals. In clinical practice, assessment of obesity as a risk factor for cardiovascular disease (CVD) remains a challenge as even some physicians are confused. However, studies conducted in our laboratory and by other research teams around the world over the last 20 years have clearly shown that body shape is more important than body size when evaluating the risk of overweight/obesity and that high accumulation of abdominal fat (excess belly fat) increases the risk of diabetes and cardiovascular disease (CVD). The investigators now need to better understand the link between excess belly fat and atherosclerosis (the thickening of artery walls by fatty deposits, also referred to as atherosclerotic plaque), leading to complications such as angina (chest pain) and myocardial infarction (heart attacks). Using non-invasive imaging techniques such as magnetic resonance imaging, the investigators therefore propose to examine the relationships between measures of fatness and of abdominal fat and the size of atherosclerotic plaque in large blood vessels of apparently healthy human subjects. This study is also a unique opportunity to look, for the first time, at the relationship between belly fat, blood sugar, several well-known risk factors for heart disease (cholesterol, blood pressure, cardiorespiratory fitness, etc.) and the size of atherosclerotic plaques. This research program should pave the way to the development of new improved preventive/therapeutic approaches focusing not on body weight but rather on abdominal fat and associated blood abnormalities which are predictive of the development of atherosclerotic plaques leading to the premature development of heart disease.
Rationale for this study: Correction of hypocholesteremia and insulin resistance after successful eradication of HCV by combination therapy of interferon and ribavirin has been shown in several studies. The majority of these studies examined genotype 1 and some genotype 3 patients, but it is not clear if the same results can be achieved in other genotypes of HCV. Moreover, clinical data of the relationships between different adipocytokines, metabolic profiles, and HCV and treatment is of value to further understand the mechanisms for HCVrelated metabolic alterations. The present proposal is designed to address the paradox of HCV-related metabolic alterations/adipocytokine alterations and to determine how BMI influences the HCV-related metabolic alteration/adipocytokine aterations by collecting and analyzing the samples from humans with HCV infection prior to and after combination of peginterferon alpha-2b plus ribavirin For metabolic alternations: Lipid profile: After treatment, responders in both genotype I and II will experience more increase of cholesterol levels and LDL levels than nonresponders/ relapseres. Insulin resistance: After treatment, responders with both genotype I and II will experience more decrease of HOMA-IR than nonresponders/ relapseres; higher percentage of responders will achieve HOMA-IR < 2 than nonresponders/ relapseres B. For adipocytokine alternation, this study is more of exploratory propose as there is still little well established consensus.
The purpose of this study is to determine the effects of metformin on cardiovascular risk factors in postmenopausal women with metabolic syndrome.

The purpose of this study is to determine whether the daily administration of a synbiotic (oligofructose and Bifidobacterium animalis subsp. lactis Bb12) for six weeks contributes to improve the glucose tolerance and the low grade inflammation (as reflected as the plasmatic concentrations of ultrasensitive CRP, IL-6, sCD14 and LPS-binding protein) in obese subjects.
