Filter by:The primary working hypothesis is that consuming processed tomatoes frequently/daily will favorably improve endothelium and platelet function disease-risk biomarker profiles in adult men and women compared to consuming no or relatively low amounts of processed tomatoes.
The proposed research will provide important information about the role of 2 intervention diets that provide different amounts of lean beef and meet current nutrient recommendations for the treatment of Metabolic Syndrome (MetSyn), a chronic disease that is still increasing in prevalence at alarming rates. The experimental and diet designs will enable us to evaluate lifestyle interventions for MetSyn for persons who maintain weight, lose weight and maintain their weight loss, as is currently recommended in clinical practice. Importantly, the investigators will compare a diet high in lean beef (5 oz/day) which is compositionally similar (i.e., energy and nutrients) to the modified-DASH diet, a low beef diet which has become the Gold Standard for the management of cardiovascular disease (CVD) risk factors, including MetSyn. In addition, the investigators also will evaluate a moderate-high protein diet (BOLD+) that is higher in total protein (from mixed sources including lean beef, 7oz/day) than the BOLD diet, on CVD risk factors in persons with MetSyn. A follow-up study was conducted to assess dietary compliance in a sub-sample of the population at 12-months; participants were not informed of this end-point and additional consent was obtained. Hypotheses: 1. Healthful isocaloric diets that include lean beef as the primary source of protein (BOLD diet) with average (18%; BOLD) or moderate-high (28%; BOLD+) total protein intake will show similar or greater reductions in CVD risk, respectively when compared to a modified-DASH diet. 2. A healthful weight-loss diet, including lean beef as the primary source of protein in a high-moderate protein diet (BOLD+ diet), plus regular exercise (BOLD+ + ex) will reduce body weight equal to that of a BOLD + ex and DASH + ex intervention, but may improve CV risk factors (such as BP and TG), and therefore reduce the prevalence of MetSyn more than a BOLD + ex and DASH + ex intervention. 3. The BOLD diet will be more effective than the modified-DASH diet, and the BOLD+ diet more effective than the BOLD diet in maintaining the CVD benefits attained during phases 1 and 2. Dietary adherence will be better on the BOLD and BOLD + diets compared with the modified DASH diet.
The overall objective of LUCHAR Specific Aims 4.1 and 4.2 is to assess the additional contribution of cardiovascular disease (CVD) risk markers to traditional biomedical risk factors in the prediction of pre-clinical CVD. Specific Aim 4.3 will test the impact of omega-3 fatty acid supplementation on risk markers and pre-clinical markers of CVD in Hispanic patients. Specific Aim 4.3: Conduct a randomized, placebo-controlled trial of the effect of omega-3 fatty acid supplementation on vascular function as measured by brachial artery reactivity (BAR) and on circulating inflammatory markers. Hypotheses: 1. Daily omega-3 fatty acid supplementation will improve vascular function in subjects at high risk for CVD. 2. Daily omega-3 fatty acid supplementation will reduce inflammatory protein panel scores in subjects at high risk for CVD.
Purpose of study is to evaluate a thrombosis chamber model
This is a multi-center study designed to assess the accuracy and precision of the Cholestech LDX Cardiac hsCRP test for the quantitative determination of C-reactive protein (CRP) in whole blood, serum and plasma from individuals being assessed for risk of cardiovascular disease. The Cholestech LDX Cardiac hsCRP test consists of the CRP cassette and LDX analyzer and measures CRP with high sensitivity on fingerstick or venous whole blood at the point-of-care (POC). The results of this study are intended to be used for regulatory 510k filings for use as an in vitro diagnostic test.
While the deleterious effects of trans fat from industrial sources (iTFA) on cardiovascular health are well established, the impact of TFA from ruminants (rTFA) on cardiovascular risk factors has not been as well characterized. We have previously shown in men that a very high dietary intakes of rTFA (>3.5% of energy) leads to unfavourable changes in lipid cardiovascular risk factors that are similar to those seen with iTFA. However, our data also indicated that achievable intakes of rTFA that remain well above the current human consumption (1.5% of energy intake) had neutral effects on plasma lipids and other cardiovascular disease (CVD) risk factors in men. Other studies have also suggested that the LDL and HDL response to very high dietary intakes of rTFA (>5% of energy) in women may be different than in men. The general objective of the study is to investigate for the first time in a double-blind randomized controlled study the impact of high but yet achievable intake of ruminant trans fatty acids on plasma LDL-Cholesterol and other risk factors for CVD in healthy women.
The purpose of this study is to assess the efficacy of high-oleic canola oil and a high-oleic canola/flaxseed oil blend as compared to a typical Western diet on plasma lipids, fatty acid profiles, and risk factors associated with cardiovascular disease in hypercholesterolemic patients. Furthermore, the metabolism of dietary oleic acid and alpha-linolenic acid contained in high-oleic canola oil and flaxseed oil will be investigated.
Given the known increased risk of heart disease in hemodialysis patients, this study aims to evaluate the change in both size and function of the heart by using cardiac magnetic resonance imaging (MRI) in patients undergoing either daily long (4 hours, 6 times weekly), daily short (2 hours 6 times weekly), or alternate day conventional (4 hours, 3 times weekly) and alternate day long (8 hours, 3 times weekly) dialysis for 6 months from randomization. The patients are randomly put in the groups based on predetermined randomization schedule and the cardiologist trained in cardiac MRI readings is blinded to the patient treatment schedule. Given that changes in heart function may be seen with cardiac imaging techniques within 6 months, the expectation is that groups on daily treatment may have better outcome for this parameter as changes in volume and blood pressure may also be affected in a positive way in patients on daily dialysis.
Small body size at birth, slow weight gain during infancy and increase in body mass index after 2 years are independent risk factors for cardiovascular disease and the metabolic syndrome. There is a large gap in our understanding of how early growth affects the cardiovascular system. Possible mechanisms include alterations in body composition, in cardiac structure, in vascular function, in renal function and epigenetic processes. The Objective is to determine how size at birth and growth during infancy and childhood affect: body composition, cardiac structure and function, vascular and endothelial function, renal function, metabolic status and transcriptional and epigenetic characteristics.
The purpose of this study is to determine the safety and tolerability of the dietary supplement Coenzyme Q10 in hemodialysis patients.
