Filter by:The purpose of this study is to evaluate the long term effectiveness of the dietary portfolio, consisting of viscous fibers, soy products, nuts and plant sterols, as well as the effects of removing single food components from the dietary portfolio on cholesterol reduction and other cardiovascular risk factors.
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.
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.
Although strong clinical evidence exists that patients with diabetes should achieve certain clinical goals (i.e. HbA1C, BP, LDL, etc.), to reduce morbidity and mortality national surveys indicate that only a minority of people with diabetes achieves these goals. Hypothesis: combination of nurse case management and enhanced behavior change counseling will improve outcomes for glycemic control, blood pressure and cholesterol in high risk patients with Type 2 diabetes when compared to usual care over a 3 year period. Study design- The study will be a three year randomized control trial that will select patients that have either A1C >8.5, LDL >130, or BP >140/90. Nurse case managers, trained in clinical guidelines and brief behavior change counseling techniques (motivational interviewing), will aim to foster patient adherence in the experimental group patients. Nurse case managers will use standing orders to set an implementation of clinical guidelines (for diabetes, hypertension, hyperlipidemia and depression) with individual follow up. A total of 820 patients between the all 9 (6 Hershey Medical Center and 3 Reading Hospital affiliated clinics) will be sought. One third of the study patients will be recruited from the underserved Hispanic population in the Reading area. Patients will be randomized by physician i.e. one physician will be randomly assigned to have all their patients co-managed by a nurse case manager; the other will have usual care without any contact with nurse case manager. Nurses will be trained and then initiate a small pilot study in July thru August. Full recruitment and initiation of study will begin in September 2006. Clinic Activities - Each nurse will be responsible for 3 clinics. Nurses will work under the supervision of the primary care physicians. A set of clinical guidelines will be developed with physician input that will serve as the over-riding framework for the nurses. Outcomes - Over a three-year period the investigators will evaluate clinical response (improvements in A1C, BP, LDL, and depression when present) as well as a series of other measures that will be obtained by surveys (patient satisfaction, quality of life, self-management behaviors). Provider satisfaction will be measured using a standardized tool. Finally, cost effectiveness of the intervention and evaluation of the potential barriers to implementation will be studied.
This is a 12-week clinical trial in participants with mixed hyperlipidemia to study the effects of MK-0524B on lipids.The primary hypothesis is that MK-0524B (dosed as MK-0524A coadministered with simvastatin) will be superior to atorvastatin on decreasing the low denisity lipoprotein cholesterol (LDL-C)/high-density lipoprotein cholesterol (HDL-C) ratio for the following dose comparisons: 2g/20 mg MK-0524B versus 10 mg atorvastatin, 2g/40 mg MK-0524B versus 20 mg atorvastatin, 2g/40 mg MK-0524B versus 40 mg atorvastatin, and 2g/40 mg MK-0524B versus 80 mg atorvastatin.
To evaluate the efficacy and safety of ezetimibe/simvastatin and niacin in patients with high cholesterol.
Evaluation of the efficacy of rosuvastatin 10mg, rosuvastatin 20mg and pravastatin 40mg in subjects with dysbetalipoproteinemia.
open-label, multiple dose, single-group, 12 week trial in HIV-infected patients with hyperlipidemia while using lopinavir/ritonavir; both male or female subjects.
The current study is designed to assess the effect of a conventional cooking oil (hydrogenated oil) and a reformulated fat low in trans fatty acids on cardiovascular disease risk factors.
