Filter by:The trial will test whether the Alive email-delivered health behavior program can improve subjects' physical activity, fruits and vegetables and saturated/trans fats and added sugars.
The project aims to examine the efficacy of a 12-week intake of alginate based ready to drink supplement on development in body weight and body composition, and risk markers for type-2 diabetes and cardiovascular disease in obese subjects.
This is a multi-center trial that will evaluate the safety, feasibility, and cost effectiveness of discharging patients, who have had successful percutaneous coronary intervention (PCI) and deployment of the AngiomaxTM closure device, 6 hours after against 24 hours after the procedure. Patients will be randomized in a 3 (test): 1 (control) fashion and will have a study population of 600 patients over 6 investigational sites all within the United States. Patients <65 years old will be chosen in order to stay within the low risk group and will be followed up after 24 hours, 7 days, and 30 days via phone or office visit. The primary endpoint will be a composite of major adverse cardiac and cerebral events, and the incidence of major bleeding or vascular complications. Data acquired from the study, such as blinded financial information and patient satisfaction surveys, will be used in order to evaluate cost analysis and safety of the procedure.
Endothelial dysfunction, or abnormal functioning of the lining of blood vessels, appears to be a key process in the development of cardiovascular disease. Endothelial dysfunction appears to be caused by both sleep disordered breathing and obesity. As endothelial dysfunction is among the first clinical marker that predicts future cardiovascular events, understanding molecular mechanisms leading to impairment of endothelial function is very important. Endothelial function requires the proper functioning of endothelial nitric oxide synthase (eNOS). eNOS activity is tightly regulated by caveolin-1, a protein important in the formation of cellular structures called caveolae. Low levels of caveolin-1 facilitate optimal nitric oxide synthesis in endothelial cells as caveolin-1 helps to spatially organize eNOS in close proximity to signaling proteins that are important for eNOS activation. In certain diseases however, the balance of caveolin-1 and eNOS can be disrupted resulting in impaired nitric oxide synthesis and leading to endothelial dysfunction. The investigators therefore seek to characterize levels of caveolin-1, and correlate this with the presence or absence of sleep disordered breathing, obesity, and cardiovascular disease. The current IRB protocol covers the performance of fat biopsies on subjects who have recently completed a sleep study either in the Center for Sleep Medicine or in our sleep laboratory and were found to have sleep disordered breathing or no sleep disordered breathing, subject with sleep disordered breathing who have been treated successfully with continuous positive airway pressure for 3-6 months, and subjects undergoing other studies in our lab who are obese or non-obese and subjects who have known cardiovascular disease and subjects without known cardiovascular disease.
Health outcome studies should examine food patterns, because foods are consumed together and nutrients are metabolized jointly. To examine associations between food patterns and markers of systemic and vascular inflammation at baseline, in a population-based cohort in Malmö, Sweden, and after 13 years of follow-up food pattern associations with CVD incidence.
Cardiovascular disease (CVD) continues to rank high among the leading causes of morbidity and mortality in adults worldwide. While diet and increased physical activity constitute the primary preventive health approach, the role of plant-based bioactive compounds has attracted much attention due to their unique cardio-protective benefits. Several epidemiological studies suggest that dietary patterns characterized by relatively high intake of fruits and vegetables are significantly associated with reduced risks of coronary heart disease and stroke. Dietary bioactive compounds are potent anti-oxidants and anti-inflammatory agents, thereby counteracting oxidative damage and inflammation, which underlie the pathogenesis of CVD. However, this area is really lacking of a good set of chemistry, bioavailability and efficacy data that is vital for nutrition researchers and doctors to emphasize their role in the prevention and treatment of clinical outcomes at different stage of CVD, and dissemination of this information to the general public. Cambridge Theranostics has focused its efforts on developing products that can prevent the damaging oxidation of lipoproteins that leads to heart attacks and stroke, and on understanding the cause of that damage. Extensive literature shows that Lycopene, Resveratrol and Soy Isoflavones are key ingredients in diets that long been known to reduce the risk of heart attack and stroke. However, they are normally poorly absorbed (not 'bioavailable'). The investigators unique production process presents Lycopene, Soy Isoflavones and Resveratrol to the body in a form that it can easily absorb and use. The aim of the current study is to perform and compare bioavailability and absorption of those three different dietary antioxidants and their combinations. The study is funded by Cambridge Theranostics and will be done on healthy volunteers of various ages with 30 people in each product group. It will be conducted on the primacies of Cambridge Theranostics in Babraham Research Campus. And managed by the team of experienced professionals employed by Cambridge Theranostics. The study will last about 12 months including recruitment process, screening process, periodical blood samples collection and examination and statistical analyses at the end.
General practitioners (GPs) and patients find it difficult to talk about risk of future disease, especially when patients have asymptomatic conditions, and treatment options are unlikely to cause immediate perceptible improvements in well-being. Further studies in risk communication for disease prevention are needed, as are studies about risk communication training for GPs. Aim: 1) to systematically develop, describe and evaluate a complex intervention comprising a training programme for GPs in risk communication and shared decision-making, 2) to evaluate the effect of the training programme on real-life consultations between GPs and patients with high cholesterol levels, and 3) to evaluate patients' reactions during and after the consultations. Hypothesis: 1) patients have better adherence to chosen treatment. The effect of the complex intervention, based around a training programme, will be evaluated in a cluster-randomised controlled trial with an intervention group and an active control group with 40 GPs and 280 patients in each group. The GPs receive a questionnaire at baseline and after 6 months about their attitudes towards risk communication and cholesterol-reducing medication. After each consultation with a participating high cholesterol-patient, the GPs will complete a questionnaire about decision satisfaction. The patients will receive a questionnaire at baseline and after 3 and 6 months. It includes questions about adherence to chosen treatment, self-rated health, patient enablement, and risk communication and decision-making effectiveness. Prescriptions, contacts to the health services, and cholesterol level will be drawn from the register of the National Health Service of Denmark at baseline and at 6 months. In both intervention group and active control group, 12 consultations will be observed and tape-recorded. The consultations will be divided between 4 GPs with each 3 patients. The patients from these 24 consultations will be interviewed immediately after the consultation and re-interviewed after 6 months.Eight purposefully selected GPs from the intervention group will be interviewed in a focus group 6 months after participation in the training programme. The process and context of the RISAP-study will be investigated in detail using an action research approach, in order to describe and analyse research choices, adaptation of intervention model to the specific context, and GPs' and patients' reactions to trial participation.
The purpose of this study is to understand if omega-3 fatty acids in fish oil enhance the ability of aspirin to reduce the risk of cardiovascular diseases such as heart attack and stroke in those who have diabetes mellitus.
The goal of this research is to improve communication to Veterans. The investigators want to improve how doctors and nurses talk to patients about the risk of heart attack and stroke. The investigators will give everyone in the study information about the risk for heart attack or stroke. The investigators will also provide information on how to reduce this risk. This information will be given in one of two ways. The investigators want to see which way of giving information works better for veterans. The investigators also want to assess the impact of personalized stroke risk communication to patients at risk for stroke on patient knowledge, beliefs, and preferences for risk reduction behaviors and evaluate the impact of personalized risk communication on medication adherence and blood pressure. The investigators plan to enroll approximately 100 veterans for this study. All veterans will be from the Durham VA Primary Care Clinics. The investigators will ask everyone to be in the study for 3 months.
The purpose of The Veteran Health Study (CSP #569) is to better understand the mental and physical health of veterans as they get older. We are inviting approximately 10,000 members of the Vietnam Era Twin (VET) Registry to participate. As veterans approach their mid-sixties, it is important to understand the impact of wartime deployment on health and mental health outcomes nearly 40 years later. The investigators will assess the prevalence of post-traumatic stress disorder (PTSD) and other mental and physical health conditions for Vietnam era veterans, and explore the relationship between PTSD and other conditions. CSP #569 involves 3 phases of data collection. In Phase I, VET Registry members are invited to complete a paper and pencil questionnaire including items on physical and mental health, disability, health behaviors, demographic information and use of health care services. After completing Phase I, VET Registry members are invited to Phase II which involves a telephone interview about mental health. In Phase III, some of those who participated in Phase I will be invited to a sub-study confirming self-reported heart disease and diabetes using a provider survey. Data collected for CSP #569 will be combined with existing VET Registry data. This will provide a rich picture of the health of Vietnam era veterans and the influence of PTSD on the lives of veterans.
