Filter by:The purpose of this trial is to re-evaluate the potential role of diet in modulating cardiovascular risk factors. If potent lipid-lowering effects through novel dietary interventions can be demonstrated, then diet may again be seen as providing an alternative to drug therapy in the primary prevention of cardiovascular disease. Aims: - To determine the percentage of lipid clinic attendees interested in making a serious dietary change. - To determine the extent to which a self selected dietary portfolio combining viscous fiber foods (oat & barley β-glucan, psyllium, etc.), soy and vegetable protein foods (soy milk, soy meat analogues and almonds) and plant sterols (sterol margarine) in the same diet be significantly more effective in reducing LDL-cholesterol and other markers of cardiovascular disease risk than conventional dietary advice. - To determine whether this effect can be maximized by more frequent follow-up, and what, if any, would be the relationship between dietary compliance and reduction in LDL-C.
Low and very low carbohydrate diets, such as the Atkins' Diet, have recently gained attention for their potential health benefits from weight loss and have gained some scientific support from a growing number of studies. Benefits have been noted in relation to raised "good" cholesterol, lower "bad" cholesterol and triglycerides. Other studies have shown an advantage in substituting vegetable fat for carbohydrate in insulin resistant individuals and in some instances in type 2 diabetes where improvements were seen in "good" cholesterol and blood sugars. At the same time, our research have been exploring diets containing less processed carbohydrates and other components which in combination (portfolio diet) have a similar cholesterol lowering effect to drug therapy. Therefore we wish to determine whether our cholesterol-lowering components (portfolio diet) should be incorporated into lower carbohydrate diets especially to preserve "good" cholesterol and lower "bad" cholesterol for decreasing the risk of heart disease.
The study will randomize 54 primary care practices to two intervention and a comparison groups. Both interventions will involve an on-site Improvement Facilitator who will assist the practice in forming an Improvement Team, using rapid-cycle tests of change, and implementing chronic care office systems for type 2 diabetes and depression. One intervention is based on complexity science and the other is a traditional QI intervention.
The metabolic syndrome is a highly prevalent disorder, which causes atherosclerotic cardiovascular disease and is closely associated with insulin resistance. The alteration of the secretion of adipocytokines from accumulated visceral adipose tissue in the obese induces insulin resistance. The purpose of this study is to identify gene polymorphisms that confer susceptibility to the metabolic syndrome and to make up a new health guidance program based on genetic risk assessment. About 25% of male employees over 45 years old in a certain company are diagnosed with the metabolic syndrome in medical examination. We, the researchers at Nagoya University, will analyze gene polymorphism and various biomarkers of over 3500 company employees.
This study will attempt to further validate a clinical treatment plan to lower LDL values using non-prescription supplements combined with a lifestyle change and education program which could represent an alternative approach to improve compliance in group of people who are unable to take traditional medication to lower cholesterol.
The purpose of this study is to determine the effect of a comprehensive pharmacy care program on medication adherence and persistence, blood pressure, and LDL cholesterol.
Included in this study will be patients with HIV and being treated with highly active antiretroviral medications (HAART) including protease inhibitors (PI) or non-nucleoside reverse transcriptase inhibitors (NNRTI). Protease inhibitors and non-nucleoside reverse transcriptase inhibitors are very common medications in HIV treatment and are usually given with other medications as part of a standard treatment for HIV (HAART). We hope to learn more about how the levels of cholesterol-and triglyceride-carrying particles (lipoproteins) are affected by a nutritional supplement, L-Carnitine, in HIV-positive patients treated with antiretroviral medications.
This study will determine the usefulness of magnetic resonance imaging (MRI) for examining the heart or blood vessels. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. The subject lies on a table that can slide in and out of the scanner (a metal cylinder), wearing earplugs to muffle loud noises that occur during the scanning process. MRI of the heart and blood vessels, called magnetic resonance angiography (MRA), is a developing diagnostic method that permits evaluation of arteries and veins without the use of x-rays or invasive catheterization required by conventional angiography. People 18 years of age and older with known or suspected atherosclerotic disease may be eligible for this study. Participants have blood tests and MRA scanning. The MRA takes about 1.5 to 2 hours. During part of the scan, a contrast agent may be injected into a vein to brighten the images of the heart and blood vessels. Subjects are monitored with an electrocardiogram and are asked to hold their breath for about 5 to 20 seconds intermittently during the procedure. A CT scan may be done to confirm the MRA findings. CT uses x-rays to produce pictures of the heart and blood vessels. The subject lies on a bed during the scan and is given a contrast agent through a catheter inserted into a vein. Subjects are asked to hold their breath intermittently for about 5 to 20 seconds. A medicine called a beta blocker may be administered to slow the heart rate.
International studies have repeatedly documented a substantial prevalence of sexual risk behaviors and high rates of human immunodeficiency virus (HIV) and other sexually transmitted infections (STI) ranging from 5%-56% amongst long-distance truck drivers ("truckers") living in diverse international settings including India, Bangladesh, South Africa, China, Laos and Thailand. The prevalence of sexual risk factors and STI/HIV in US drivers is unknown. This proposal will provide both qualitative and quantitative data on HIV risk behaviors by interviewing and testing truckers working for established long-distance trucking firms, the sector which accounts for most of the jobs in the trucking and warehousing industry in the United States. The data obtained from this study will be used to inform the development of an HIV prevention intervention for long-haul truck drivers.
This is a 16-week clinical trial in lipid clinic patients for whom niacin therapy is appropriate to evaluate the tolerability of MK0524A versus niacin extended-release. There will be 6 scheduled clinic visits and 2 treatment groups.
