Filter by:The goal of this study is to design and implement an intensive discharge intervention for inpatients with type 2 diabetes and cardiovascular disease, and determine the effects of the intervention on post-discharge insulin adherence, glycemic control, cardiac medication adherence, hypoglycemic events, and emergency department visits and hospital readmissions.
Background: - Restricting calories can help a person reduce risk factors for heart disease. Researchers have found that not eating or drinking anything but water for 24 hours prevents the activation of a component of the immune system, called the inflammasome. The inflammasome is associated with the development of diabetes and heart disease. Researchers want to learn more about the body s response to fasting. Objective: - To explore the benefits of calorie restriction on heart health. Eligibility: - Healthy adults ages 21 32 with a body mass index between 26 and 29. Design: - Participants will be screened with a medical history, physical exam and blood test. - Participants will not eat or drink after 10 p.m. before their first visit. - Participants have breakfast at the clinic. The breakfast will be about 500 calories. Then they will not eat or drink (except water) for 24 hours. - Participants will return to the clinic the next morning. They will have blood drawn. Then they will have breakfast. Blood will be drawn again at 1 hour and 3 hours after the meal. - Blood and urine tests at the end of the fast and following the meals will be done to confirm that participants have fasted for the full 24-hour period.
Complaints about memory and thinking are common in women as they go through menopause and estrogen levels fall. The ovarian hormone estrogen is important for supporting normal cognitive function, and changes in brain activity and function occur when estrogen levels are decreased. Estrogen is also important for maintaining healthy blood vessels which also support normal cognitive function. In Alzheimer's disease and other types of dementia, there is significant damage to the blood vessels in the brain. This study will test whether changes in brain activity and function with the loss of estrogen are related to changes in vascular function. The investigators will measure vascular function using ultrasound, and brain activity using MRI scans in women who are enrolled in the Females, Aging, Metabolism and Exercise (FAME) study (NCT01712230). In the FAME study, healthy premenopausal women either take a medication to decrease their estrogen levels, or a placebo. This sub-study may provide new information about how estrogen affects vascular function and cognitive function, and lead to new ways to prevent or delay cognitive impairment or dementia.
The purpose of this study is to evaluate the prognosis of patients with resistance to antiplatelet agent and develop tailored treatment model for patients with coronary artery disease.
The aim of this study is the comparison between the effects of supplementation with omega 3 or placebo for 8 weeks in serum level of BMP-4, YKL40, HSP70, HSP27 in patients with cardiovascular disease.
Although weight reduction through physical activity-based interventions is the mainstay therapy for nonalcoholic fatty liver disease (NAFLD), its maintenance is difficult and typically unsuccessful. This affirms the extreme need for alternate and/or adjunct therapies. Although convincing data from animal studies and a few adult human studies on the benefits of a natural product, N-acetyl cysteine (NAC), in a variety of liver conditions including NAFLD have emerged, studies in children are scarce. Therefore, the aim of the study is to test the use NAC as an innovative approach to attenuate the progression of NAFD in obese children with biopsy proven NASH. The central hypothesis is that NAC supplementation will reduce liver fat and liver enzymes and ameliorate risk factors of cardiometabolic disease in children with NAFLD.
The study is a 2 year community based cluster randomized controlled trial to assess the role that a community health worker led intervention, in concert with physician education, can play in controlling the principal cardiovascular risk factors, i.e. hypertension, tobacco use, diabetes mellitus, physical inactivity and an unhealthy diet. Participants will include around 3600 adults, 35-70 years of age, from the urban community in the town of Dalkhola, Uttar Dinajpur district, West Bengal, India. The hypothesis of the study is that a community health worker based approach can result in increased control of Hypertension, Diabetes and Smoking.
The study aims to investigate - if a 7 day therapeutic fasting regimen will affect self-efficacy of patients with chronic diseases - the effects of fasting on physical and mental well-being, quality of life and body awareness/image - the association between patients characteristics and the perceived health benefit after fasting - the association between Diagnosis according to traditional Chinese medicine and physical and mental well-being during the course of fasting - experiences and perceptions of patients during fasting therapy
The primary goal of this Multicenter Study is to develop and to evaluate a method for measuring donor-specific cell free DNA in blood samples from transplant recipients as markers of rejection. Blood samples obtained periodically from heart transplant recipients are assessed for cell free DNA relative to clinical data in order to determine whether changes in the level of cell free DNA indicate rejection. This research study proposes testing a blood sample obtained from the heart transplant recipient. The research seeks to establish whether this blood test will show when the patient is beginning to or already rejecting the transplanted heart. BACKGROUND Identifying if a transplant patient is beginning to or already rejecting the heart is necessary, so that appropriate treatment can be started to halt the rejection. Heart catheterization with biopsy is the usual method used for assessing whether a patient may be rejecting the heart. There are also a number of other methods that transplant physicians will use to look for signs of rejection including other blood tests, echocardiograms, obtaining pressure readings during heart catheterization, and micro-array testing of blood obtained during biopsy. These technologies are limited in ability to consistently and accurately identify the presence of rejection. The usual method of checking for rejection involves obtaining a sample of the heart tissue (heart biopsy); biopsy can only be accomplished through heart catheterization which is an invasive procedure that has risks associated with disturbing the heart such as puncturing the heart or causing the heart rate to change or damaging tissue in the heart. Overtime, repeating this invasive procedure can diminish the ease of the procedure because the veins can become scarred and more difficult to access. For these reasons, researchers believe that it would be good to have a blood test that gives information about the possibility of rejection so that it may not be necessary to do as many heart biopsies. Also, a blood test may be able to provide information about the heart or about rejection that is currently not available at all.
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.
