Filter by:The study conducted a health survey among Thai adults in 2022 and found a significant increase in obesity and nonalcoholic fatty liver disease (NAFLD), leading to metabolic-associated steatotic liver disease (MASLD). The prevalence of NAFLD was 19.7%, with higher rates in individuals with metabolic syndrome and diabetes. MASLD is associated with insulin resistance and genetic polymorphisms, particularly the patatin like phospholipase domain containing 3-rs738409 variant. Additionally, physical activity was inversely related to liver disease risk, with higher step counts associated with reduced incidence of NAFLD and liver-related mortality. The study aims to investigate the impact of dietary advice and pedometer use on physical activity levels and health outcomes in MASLD patients over 24 weeks.
This project aims to implement a health prevention program for smokers or former smokers including early detection of lung cancer, cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD). The clinical activity is completed by a pre-clinical evaluation of molecular bio-markers of early diagnosis of these diseases, with the aim of strengthening the sensitivity and specificity of the screening program. The project also includes a cost-effectiveness assessment to validate the feasibility of the program. Since lung cancer, CVD and COPD are among the deadliest smoking-related pathologies, the program includes actions aimed at raising awareness among primary care physicians, increasing the smoking cessation rate of participating subjects to improve quality of life.
The main objective of this study is to test the ability of novel cardiovascular disease (CVD) prognostic tools to identify women at risk for future CVD. We plan to establish a cardiovascular health screening program at the St. Boniface Hospital and to test the efficacy of these tests for predicting adverse cardiovascular outcomes amongst a cohort of 1000 Manitoban women aged 55 years and older in the 5-year period after screening. A second purpose of this project is to identify novel CVD biomarkers that may indicate a person is at risk for cardiovascular disease. Therefore, we plan to ask participants for permission to collect and store a sample of both their blood and stool for future research.
In North Carolina, and nationally, cardiovascular disease (CVD) is the leading cause of death and disease among adults. North Carolina adults have high rates of CVD behavioral risk factors such as physical inactivity, unhealthy eating habits, smoking, and being overweight and obese. To help reduce these risks, researchers from the University of North Carolina at Chapel Hill Prevention Research Center (UNC PRC) will test the effectiveness and implementation of Carolina Heart Alliance Networking for Greater Equality (CHANGE). CHANGE is a health promotion strategy to link public health and clinical services through community health workers (CHWs). Primary care clinics, public health, and CHWs all have strengths in addressing chronic disease risk factors, but there is a widely recognized gap in the coordination among them. The CHANGE strategy will use CHWs as members of primary care and public health teams to distribute a behavioral change intervention called Heart-to-Health to a total of 480 clinic patients at risk for CVD. Heart-to-Health is an effective lifestyle and medication adherence intervention that includes a computerized decision aid to guide delivery of tailored counseling sessions. The counseling sessions are focused on diet, physical activity, tobacco cessation, and medication adherence and are facilitated by CHWs using tablet computers. The CHWs will use tablet computers to communicate with a medical home team about important patient health information to be acted on in real time. The CHWs also will link participants to public health and other community based resources to support behavior change. The CHANGE strategy will be tested in one underserved, rural community and then replicated in a second community. Researchers from the UNC PRC will examine whether CHANGE is effective at increasing the reach of clinic and public community services to at risk populations and at improving composite coronary heart disease risk.
Clopidogrel is a prescription medicine used to minimize blood clot formation in patients with cardiovascular disease, particularly those undergoing heart catheterization and stroke. A substantial amount of medical evidence has proven that patients with stroke or heart diseases can benefit from this medicine. However, significant variability in such expected benefits has been found among individuals receiving clopidogrel, with some patients not having the benefit of reduced complications and adverse cardiovascular events. Prior studies have demonstrated a significant association between certain variants on patient's genes (e.g., CYP2C19) and poor response to clopidogrel and, therefore, major adverse cardiovascular events. Variation in other genes and other factors such as platelet activation, weight, diabetes mellitus (a medical condition that produces high blood sugar), concomitant use of other drugs, and smoking status have also been proposed to be related to the same adverse outcomes. In this study, the investigators would like to determine a possible association between these genes and the response to the medication among Caribbean Hispanic cardiovascular patients on clopidogrel. In other populations, it is known that patients with certain genetic variants have lower or magnified responses to this medication when compared to those individuals taking the same dose and not carrying the genetic variations. However, a fundamental gap remains in understanding whether the genomic diversity of Caribbean Hispanics accounts for the observed high inter-individual variability of clinical outcomes to preventive dual antiplatelet therapy (DAPT) with clopidogrel.
The purpose of this study is to determine whether low estrogen levels in young women with hypothalamic amenorrhea (premenopausal HypoE) is associated with risk factors for cardiovascular disease. For this study, the investigators will measuring vascular function and immune markers on: - young women with hypothalamic amenorrhea (>3 months of no menstrual cycle due to low estrogen) - young women with regular menstrual cycles not on hormone therapy. - recently menopausal women (<3 years from final menstrual period) not on hormone therapy. Premenopausal HypoE participants will then be randomized to use either an estrogen patch or a placebo patch (no active medicine) for 3 months, followed by estrogen or placebo patch plus progesterone or placebo pills for 2 additional weeks. The investigators are looking to see if estrogen improves vascular and immune function.
The purpose of this study is to test if having a Veteran peer health coach will improve blood pressure control among Veterans with high blood pressure and at least one other Cardiovascular disease (CVD) risk factor. The intervention will deliver brief health messages, discuss goal setting, and action planning around health behavior changes shown to decrease CVD risk, including healthy diet, regular to moderate-intensity physical activity, and smoking cessation. Facilitators, barriers, and costs of the intervention will be determined.
The purpose of this study is to determine whether the use of rosuvastatin in Human Immunodeficiency Virus (HIV) infected individuals lowers inflammation in blood vessels, improves blood circulation in the small arteries that provide nutrients to the heart muscle and improves neurocognitive function.
Atherosclerosis and its related cardiovascular morbidity and mortality, underlie many chronic diseases. Most atherosclerotic patients have multiple cardiovascular risk factors, which potentiate each other, causing a huge burden on health systems. In order to improve the understanding and treatment options of atherosclerosis, it is necessary to identify common basic pathways in its pathogenesis. Oxidative Stress (OS) has a major role in the pathogenesis of atherosclerosis; however, good biomarkers to determine OS are still missing.
Cardiovascular disease (CVD) is the leading cause of death in the United States. Despite strong evidence that reducing low-density lipoproteins (LDL) with statins successfully lowers CVD risk, physicians under-prescribe statins, physicians fail to intensify treatment when indicated, and more than 50% of patients stop taking statins within one year of first prescription though such therapy typically should be life-long. In this study, we will test the effectiveness of different financial incentives in increasing statin use and reducing LDL cholesterol among patients with poor cholesterol control who are at very high risk for CVD. The application of conceptual approaches from behavioral economics offers considerable promise in advancing health and health care. We will test these approaches among patients at very high risk of CVD at Harvard Vanguard Medical Associates. Using a 4-arm, cluster-randomized controlled trial, we aim to answer these questions: [1] How does the provision of patient incentives compare to no incentives at all? [2] Is success with patient incentives improved by increasing the financial amounts? [3] Are results sustained after incentives and other interventions are withdrawn? Study Objectives and Hypothesis Aim 1: To evaluate the effectiveness of varying patient incentives on improvement in LDL cholesterol relative to usual care during a 3-month intervention among patients at high risk of CVD. H1: Each of the incentives will be more effective than usual care in reducing LDL cholesterol. Aim 2: To evaluate the relative effectiveness of those intervention arms superior to control in reducing LDL cholesterol. H2: Higher incentive amounts for patients will be more effective than lower incentive amounts. Aim 3: To evaluate the impact of each effective intervention in sustaining adherence and reduced LDL after the 3-month intervention period. Aim 4: To conduct a rigorous process evaluation to examine why some incentives were more effective than others and to address other factors relevant to broader implementation.
