Filter by:The purpose of this pilot study is to provide data on the feasibility of conducting a large clinical trial on the polypill (combination of aspirin, angiotensin converting enzyme inhibitor, thiazide diuretic, and statin) for primary prevention of cardiovascular disease (CVD). We hypothesized that A "polypill" comprising the aforementioned four components would significantly reduce the estimated 10-year total CVD risk score with high adherence and no significant increase in adverse effects compared to the standard practice.
The purpose of this study is to determine the concentration of omega-3 fatty acids in plasma, blood and abdominal fat before and after bariatric surgery to provide guidance for future studies.
This is a Phase I, multi-center, open label study designed to assess the safety and feasibility of the injectable BL-1040 implant to provide scaffolding to infarcted myocardial tissue.
Coronary heart disease (CHD) is the largest contributor to morbidity and mortality in the Western world and is associated with high-calorie diet, high body mass, and a variety of other factors. CHD can lead to myocardial infarction (MI) and other embolic events. In some areas such as France, though, a paradox of high-cholesterol diets but low CHD and MI incidence have been found. This paradox has been traced to the consumption of red wine. Further research suggests that components of the grapes used in red wine may be the source of the cardio-protective factors that have resulted in the French paradox. These components are also present in purple grape juice (PGJ). PGJ has been shown to have a variety of potential cardio-protective effects, including inhibition of platelet aggregation. Since PGJ does not contain alcohol it may provide an additional benefit by avoiding the physical and social implications of alcohol abuse. Since most of the research of PGJ has been in vitro, though, and the few studies in vivo have been in cross-over studies and over very short durations of 7 to 14 days, additional research is required to determine whether the long-term consumption of PGJ is of additional and sustained benefit, similar to long-term use of red wine in France. The proposed study is a 2 arm randomized, controlled (double-blind) study of PGJ and a calorically-matching placebo drink in 100 healthy individuals.
The purpose of this study was to determine whether, in patients with type 2 diabetes and pre-existing disease of the heart and the circulatory system and/or the kidney, aliskiren at a target dose of 300 mg once daily (compared to placebo), on top of conventional treatment, reduces death and disease caused by the heart, the circulatory system and the kidney. AMENDMENT 4 RATIONALE (MARCH 2012) : Protocol amendment 4 served to address the data monitoring committee recommendation dated 14 Dec 2011 to discontinue study treatment in all participating patients. It also addressed the subsequent Health Authorities request to implement a 12 month safety follow-up period (actual duration was 9 months in average) post study drug discontinuation.
This study is being conducted to provide initial safety and tolerability data as well as to provide PK data on potential interactions when GW856553 and rosuvastatin are co-administered in healthy male adults
The specific aim of this study is to collect preliminary data on the feasibility and validity of home-based data collection methods to measure four constructs: - Physical Activity: Real-time assessment using Ecological Momentary Assessment (EMA) and pedometers - Cardiorespiratory Fitness: Step test - Anthropometry: Waist and hip circumference measurements - Environmental Variables: Examples include density of neighborhood physical activity facilities (including gyms, parks, walking trails), crime, land use mix, and transportation variables, collected by participants using EMA.
Epidemiological studies definitively show that fruit and vegetable consumption is positive for health and more specifically for cardiovascular diseases (CVD) prevention. In France, among fruits, those which are the most frequently consumed are citrus fruits essentially as juices and more specifically as orange juices. However, their health effects have been poorly studied so far. Citrus fruits contain vitamin C associated with various phytomicronutrients i.e. carotenoids (essentially -cryptoxanthin) and polyphenols. Each fruit contains specific compounds: hesperetin in orange, naringenin in grapefruit, eriodyctiol in lemon. Some scientific studies performed either in vitro or in animal models demonstrated properties of these micronutrients which could contribute to a positive health effect of citrus fruits on vascular protection. However data are still missing. The main goal of this project is to characterize the effect of orange juice consumption on vascular disease risk factors and to evaluate the specific role of their micronutrient compounds (polyphenols and carotenoids) in this protection. To reach this goal, a randomized "cross-over" clinical study will be performed on volunteers presenting a mild hypercholesterolemia. They will consume for 4 weeks an orange juice or a reconstituted drink similar to the orange juice for its composition in carbohydrates, minerals, vitamin C and folates but without phytomicronutrients. The effect of the juice consumption on the vascular function will be monitored exploring lipid abnormalities in plasma, measuring endothelial vasoreactivity (FMD) (Flow Mediated Dilatation), as well as endothelial dysfunction, thrombosis, inflammation and oxidative stress biomarkers in plasma. Comparison of urinary metabolomes after orange juice consumption or that of the reconstituted drink will lead to the identification of the metabolic pathways modulated by the orange juice micronutrients. Moreover ELISA tests for the two major flavanones from citrus fruits (hesperetin and naringenin) will be developed. They will be used to determine the plasma levels of these molecules in order to analyze the relation "ingested quantity - bioavailable quantity - physiological effect". The results obtained in this project will allow clarifying citrus fruit effects, and particularly orange juice, in vascular protection.
The purpose of this study is to test the effects of natural vs. man-made trans fatty acids (trans fats) on blood cholesterol.
Dietary fructose potently exacerbates the dyslipidemia associated with obesity, insulin resistance and accelerated atherosclerosis. In a randomized crossover outpatient study of 15 overweight adults, we will measure the increase over 4 hours in serum VLDL triglyceride palmitate made by the liver from each single oral dose of fructose (0.5 g/kg), fructose:glucose 1:1 (1 g/kg) or fructose:glucose 1:1 (2 g/kg). Our hypotheses are that the synthesis of palmitate from dietary fructose will be 1) greater when consumed with glucose and 2) show a dose-response. The lipogenic responses will be compared and correlated with markers of carbohydrate and lipid flux measured after fasting and post-fructose. The results will serve as a guide to the development of a new outpatient probe of the de novo lipogenic pathway in subjects who vary in their lipogenic response to oral fructose. These studies should ultimately yield valuable new information about the mechanisms linking dietary carbohydrate to elevated triglycerides, diabetes and cardiovascular disease.
