Filter by:Background: Metformin treatment has beneficial effects on both glucose and lipid metabolism. Whereas there is general agreement that the blood glucose lowering effect of metformin results from inhibition of hepatic gluconeogenesis, it is less clear exactly how the drug lowers blood triglyceride concentration. There are indications that it enhances hepatic free fatty acid (FFA) oxidation thus diminishing substrate for reesterification and resecretion as very-low-density-lipoprotein (VLDL) triglycerides (TG). However, the liver is not easily accessible for sampling in humans and data on the clinical effects of metformin in the liver are therefore lacking. This may change due to the increasing use of the positron emission tomography (PET) technique. Using PET isotopes (11C or 18F) coupled to either palmitate or a fatty acid analogue, it is possible to non-invasively measure hepatic fatty acid handling. Aim: To determine how 3 months metformin treatment (1000 mg twice daily) affects hepatic lipid and glucose metabolism in patients with newly diagnosed type 2 diabetes. Design: Randomized, placebo controlled, double-blind parallel study with patients receiving either metformin or placebo. A control group of BMI and age-matched non-diabetic individuals will receive metformin for 3 months. Hypothesis: Metformin lowers VLDL-TG secretion and circulating triglycerides by increasing hepatic fatty acid oxidation
This is a two-part Phase 1 placebo-controlled, double-blind, randomized single and multiple ascending dose study. In Part A, CAT-2003 is administered as a single dose; at two doses (1000 and 2000 mg), subjects will return for a second dose of CAT-2003 or placebo after a high fat meal. In Part B, CAT-2003 is administered for 14 consecutive days.
The objective of this study is to evaluate changes in Framingham score (from low to moderate, from moderate to high) based on changes in lipid profile and other parameters from baseline to 48 weeks of HAART in naïve patients or patients in second line of treatment, considering LPV/r vs EFV based HAART. The null hyphotesis is that there is an increased Framingham score in patients treated with LPV/r as second line treatment and in patients treated with LPV/r or EFV regimen as first line treatments.
The purpose of this study was to evaluate the effects on lipids and diet of a low-intensity dietary counseling intervention provided by the primary care physician (PCP), in patients at risk for cardiovascular diseases
This is a double-blind, randomized study designed to compare the efficacy and safety of two fixed combinations of fenofibrate / simvastatin 145/20 mg and fenofibrate / simvastatin 145/40 mg tablets vs. matching monotherapies in subjects with abnormal fat (lipids) in the blood and at high risk of cardiovascular disease. Fenofibrate is a treatment that lowers fat in blood. It is prescribed in patients with high levels of triglycerides (TG). The drug has been marketed in more than 80 countries since 1975. Simvastatin is also used for the treatment of patients with a high level of cholesterol. These have also been marketed worldwide for more than 20 years. It is important to treat high levels of fats in the blood because it has been shown that even mildly elevated level of lipids in the blood can lead to diseases of the blood vessels. It has been shown in several studies and in clinical practice that the combination of fenofibrate plus simvastatin can lead to improved effects on blood fats, compared to treatment with simvastatin or fenofibrate alone. The main objective of the study is to compare the efficacy of the two fixed-combinations (FC) -fenofibrate/simvastatin 145/20 mg tablet and fenofibrate/simvastatin 145/40 mg tablet in reducing TG and increasing high density lipoprotein cholesterol (HDL-C) versus simvastatin 20 mg or 40 mg, and in reducing low density lipoprotein cholesterol (LDL-C) versus fenofibrate 145 mg.
Primary Objective: To examine changes in expression of genes [particularly ABCA1 and SREBP2] involved in reverse cholesterol transport (RCT) in monocytes from HIV-infected subjects starting antiretroviral therapy and the different effect of NNRTI and PI based regimens Secondary Objective: To examine changes in monocyte intracellular cholesterol content in HIV-infected subjects starting antiretroviral therapy and the different effect of NNRTI and PI based regimens
The purpose of this randomized trial is to study the efficacy of a novel social propagation intervention which integrates social network induction with health education for weight and metabolic control among patients with type 2 diabetes, BMI of 25-30+, and cardiovascular disease. The intervention takes place in the form of a community health program, where participants who enroll in this program will be asked if they would like to take part in the study to evaluate its efficacy. Thus, the investigators will study the efficacy of social networks in propagating changes in lifestyle factors for diabetes and chronic disease management
Tree nuts (almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachios and walnuts) are an important source of unsaturated fatty acids, vegetable protein, and fibre, as well as minerals, vitamins, and phytonutrients. Although heart disease risk reduction claims for nuts have been permitted in the U.S. and general dietary guidelines and recommendations from heart associations recommend the consumption of nuts for heart protection, diabetes associations have not addressed nuts in their most recent recommendations. This omission is despite heart disease being a major cause of death in diabetes. There remains insufficient information on the usefulness of these foods in diabetes. To improve evidence-based guidance for tree nut recommendations, the investigators propose to conduct a systematic review of the effect of tree nuts on diabetes control and features of the metabolic syndrome. The systematic review process allows the combining of the results from many small studies in order to arrive at a pooled estimate, similar to a weighted average, of the true effect. The investigators will be able to explore whether eating tree nuts has different effects between men and women, in different age groups and background disease states, and whether or not the effect of tree nuts depends on the dose and background diet. The findings of this proposed knowledge synthesis will help improve the health of Canadians through informing diabetes association recommendations and heart association recommendations where they relate to diabetes.
The primary objective of the study is to compare the efficacy of Rosuvastatin 5 mg once daily with Rosuvastatin 10 mg once daily by assessment of the number of patients with hypercholesterolemia reaching the LDL-C target goal of <100 mg/dL after 12 weeks of therapy.
The aim of this study is to determine the effect of habituation to diets with different types of carbohydrate (simple-carb, refined-carb, unrefined-carb) on selected Cardiovascular Disease (CVD) risk indicators.
