Filter by:The VIP-U Study is a clinical trial designed to investigate the effect of ustekinumab (Stelara) and placebo on reducing vascular inflammation and cardiometabolic risk biomarkers in patients with moderate to severe psoriasis. This study will look for systemic vascular inflammation in study participants with a test called FDG PET/CT (fluorodeoxyglucose-positron emission tomography/computed tomography). The study will also look for cardiometabolic identifiers (heart disease and metabolic factors) in blood samples, including markers of high cholesterol, cholesterol efflux function (the ability of cholesterol to move in the body), metabolic factors, and inflammation. The study will also examine the effects of ustekinumab compared to placebo on psoriasis activity, severity and safety.
The primary objective of this pilot study will be to examine the effects of consuming whole grains, differing in the degree of processing, on insulin sensitivity and other cardiometabolic risk factors. The overall aim will be to assess feasibility of the test diets and to generate preliminary data.
The purpose of the proposed pilot study is to evaluate the effects of a soy protein isolate with naturally occurring isoflavones on the properties of HDL-C (total HDL-C, HDL particle size and HDL function), central blood pressure, and indices of arterial stiffness.
Cardiovascular disease which includes coronary artery disease and peripheral artery disease remains the leading cause of death among women in the United States. The impact of cardiovascular in women was not recognized by clinicians for a long time. It is now evident that, women suffer the consequences of cardiovascular at rates at least as high as those observed in men but there are still major gaps in our understanding this disease in women. Hydrogen sulfide (H2S), a gaseous mediator plays an important role in the cardiovascular system. Research has demonstrated it's critical role in animal ischemia reperfusion models. Hydrogen sulfide exists in distinct biological pools in blood. Recently, the Kevil lab has pioneered the development of new analytical techniques for accurate measurement of all biological pools of H2S. By measuring these distinct pools of H2S in women with and without cardiovascular disease the investigators hope to further understanding of role of H2S in pathophysiology of cardiovascular disease. This research will help to assess the ability of H2S and its distinct biological pools to potentially be a diagnostic marker or a therapeutic target for cardiovascular disease.
The purpose of this study is to improve the health status of people living with HIV in Australia. The overall goal is to rigorously evaluate the impact of interactive health plans and self-management support on chronic condition outcomes in people with HIV. The specific aims are to: Aim 1: Using a doctor-level cluster randomised trial, evaluate the effect of interactive health plans and self-management support on coronary heart disease risk and other chronic condition outcomes in people living with HIV. Aim 2: Evaluate patient and health care provider experiences and acceptability of interactive health plans and self-management support. Aim 3: Evaluate intervention cost-effectiveness and effect on health service utilisation.
The major source of mortality and morbidity of diabetic patients is cardiovascular disease (CVD). Moreover, in CVD patients the presence of diabetes is associated with the increased risk of major adverse cardiac events as compared to patients without diabetes. The pathophysiology of macrovascular complications in T2D is not fully understood and involves: 1/ induction of oxidative stress, 2/ the formation of advanced glycation end products, 3/ activation of blood coagulation and platelet aggregation, 4/ increased inflammation, 5/ altered secretion of adipokines in obese subjects and 6/ endothelial dysfunction. All those mechanisms in T2D patients could potentially be a subject of new therapeutic interventions. A therapy that continues to show promise in T2D patients with CVD is supplementation with omega-3 polyunsaturated fatty acids (PUFA). Clinical studies have indicated that omega-3 PUFA decrease the risk of major cardiovascular events, although the mechanism of action is not completely understood. Moreover, there were no trials exploring the mechanisms and outcomes of omega-3 treatment in T2D patients with CVD. Despite that fact, Polish Diabetes Association guidelines recommend the use of omega-3 PUFA in patients with diabetes in the prevention of macrovascular complications. Moreover, it is unclear whether the benefits of modifying the pathophysiological processes during supplementation with omega-3 PUFA occur only in patients with their deficiency or in all patients with type 2 diabetes. Potential benefits of omega-3 PUFA in such patients are: 1/ decreased oxidative stress, 2/ decreased platelet aggregation and reduction of hypercoagulable state, 3/ anti-inflammatory effects, 4/ improvement in endothelial function. All those effects were explored previously with inconsistent findings. There is very limited information from clinical studies on the mechanisms and benefits of omega-3 PUFA in T2D patients with CVD. The objective of the current study is to evaluate the effects of omega-3 PUFA administered on top of optimal therapy of atherosclerotic vascular disease and T2D on endothelial function, platelet aggregation and thrombotic, inflammatory and oxidative stress biomarkers.
The VITamin D and OmegA-3 TriaL (VITAL) is an ongoing randomized clinical trial of 25,871 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in individuals who do not have a prior history of these illnesses. The purpose of this ancillary study is to ascertain and adjudicate atrial fibrillation (AF) outcomes for the primary aim of testing whether omega-3 fatty acid and/or vitamin D supplementation influence atrial fibrillation risk in the general population. We also plan to examine how these agents might impact the development of AF subtypes (persistent versus paroxysmal), intermediate phenotypes for heart rhythm disorders (electrocardiographic parameters), as well as explore effects on arrhythmic death and whether baseline blood levels and/or race modify treatment effects.
The prevalence of cardiovascular disease is rising; new methods must be created to assess the cardiovascular status of patients. If cardiovascular disease can be predicted, it may facilitate prevention. An association between periodontal disease and cardiovascular has been established, but a definitive mechanism is not understood. A good first step in finding that mechanism is to look at the correlation between periodontal disease and cardiovascular disease, both of which have an inflammatory component. This study observes the level of cardiovascular disease in patients and correlates it with the presence and degree of periodontal pathogens.
Specific cardiovascular diseases, such as stroke and heart attack, have been shown to vary by ethnic group. However, less is known about differences between ethnic groups and a wider range of cardiovascular diseases. This study will examine differences between ethnic groups (White, Black, South Asian and Mixed/Other) and first lifetime presentation of twelve different cardiovascular diseases. This information may help to predict the onset of cardiovascular diseases and inform disease prevention strategies. The hypothesis is that different ethnic groups have differing associations with the range of cardiovascular diseases studied.
African American women have among the highest rates of overweight and obesity and few meet dietary or physical activity guidelines. The investigators seek to develop a new intervention strategy that will help alleviate health disparities, thereby improving quality of life, health care costs, and disease burden. The African American Collaborative Obesity Research Network (AACORN) recommends an eco-social, community-engaged approach to behavior change that is in line with cultural values of interconnectedness and care for others. The purpose of this study is to operationalize the AACORN paradigm to promote improvements in weight status and health through a civic engagement approach. To achieve this, participants will meet in church-based Change Clubs and be led through a 6 month curriculum, which includes both lessons in cardiovascular risk reduction and a civic engagement project. Civic engagement may lead to change in individual health behaviors by increasing self-regulation and self-efficacy. The investigators will measure club members' adherence to the Change Club intervention, defined as average number of sessions attended, retention in the clubs, satisfaction with the Change Club experience and achievement of at least 50% of self-identified benchmarks for community change within 6 months. In addition the investigators will compare anthropometric factors, diet and physical activity behaviors, blood pressure, cardiorespiratory fitness, and psychosocial factors before and after participation in the Change Club intervention.
