Filter by:The overall goal of this project is to test the hypothesis that long-term, sustained sleep restriction (SR), in women, will lead to increased cardio-metabolic risk. This will be characterized by increases in visceral adiposity, unhealthy lifestyle behaviors (poor dietary quality and low physical activity) and cardio-metabolic risk factors (blood pressure, glucose intolerance) relative to habitual sleep (HS). The investigators expect these changes to be worse in pre- compared to post-menopausal women.
American Indians (AI's) are experiencing an epidemic of stroke morbidity and mortality, with higher prevalence and incidence, younger age at onset, and poorer survival than other racial and ethnic groups. With a stroke incidence more than twice that of the general U.S. population, stroke in AI's is a public health problem of staggering scope. AI's also have disproportionate burdens of many risk factors for stroke, including hypertension, smoking, obesity, and diabetes. However, no rigorous, population-based studies of stroke prevention have included AI's. The investigators at WSU, and community partners, have designed the "Family Intervention in the Spirit of Motivational Interviewing" (FITSMI), a program delivered at the household level to encourage lifestyle changes that transform the home environment and reduce stroke risk for all residents. FITSMI uses a "talking circle" format in which facilitators guide participants to identify goals for change and create a tailored plan for sustainable implementation that may target smoking, exercise, diet, or medication adherence. FITSMI requires just 2 sessions (baseline and 1 month post-baseline), with text messaging used to boost long-term adherence. In a group-randomized trial design, the investigators will recruit 360 households where Strong Heart Family Study members aged 45 and older reside. The investigators will assign half to FITSMI and half to a control condition that receives educational brochures.
Cerebral autosomal dominant arteriopathy with subcortical infarct (CADASIL) is a lethal disease caused by a gene mutation that affects arteries in the brain. Symptoms include migraines, strokes, memory loss, and dementia. There are no treatments. Researchers want to study people who have CADASIL to learn more about it. Objectives: To learn more about CADASIL by studying people who have it. Eligibility: People ages 18-100 who were diagnosed with CADASIL in the past 5 years and can make their own decisions Design: Participants will be screened in another NIH protocol. Participants will have 3 visits over 2 years. These may include: - Physical exam - Thinking and concentration tests - Blood tests - Skin biopsy: A small skin punch is removed from the arm or leg - Eye exam and eye imaging tests - Fluorescein angiogram: A catheter is placed in an arm vein. Dye is given through the catheter and travels to the eyes. - EndoPAT: A small clamp on the fingertip measures blood volume. - Cardio-ankle vascular index (CAVI): Artery stiffness is tested with blood pressure cuffs on the arms and legs. Soft electrodes on the skin measure heart signals. - Brain MRI or MRA: They lie on a table that slides in and out of a tube that takes pictures. They may get a contrast agent in their vein. It brightens the brain so researchers can see where blood flows. - CT scan of the heart: They lie on a table that slides in and out of a machine that takes pictures. - They get contrast dye injected through a catheter. They may get a medicine that makes their blood vessels bigger or slows their heart rate.
This study evaluates how genetic variations in complement, a part of the immune system, affect cardiovascular risk in adolescents.
The investigators developed novel quality improvement intervention consisting of a personalized decision support tool, an educational program, a performance measure, and an audit and feedback system to encourage the adoption of the VA/DoD guidelines for the use of statin medicines. The investigators then performed a cluster randomized trial of the intervention in a single clinic.
This study will investigate whether small changes (nudges) made in a cafeteria, where participants eat for 4 weeks, can improve their food behavior and health during the 4 weeks, and 6 weeks and 6 months after their stay. Half the participants will be exposed to one of four types of nudges (focused on reducing salt intake, increasing vegetable intake, reducing portion size, and a combination of these nudges), and half of the participants will eat in the cafeteria as it is currently, without modifications.
Twitter use is surprisingly well represented across broad demographic population segments and health-related messages. The promise of using Twitter is that its use is growing rapidly, it allows the investigators to view communications that were impossible to intercept before, and it potentially provides information faster and less expensively than collection from other media channels. Prior work also supports that social media interventions can improve health behavior change (e.g. weight loss, physical activity) and outcomes.The overarching goals of this proposal are to understand the uses and limitations of this communication channel to improve patients' ability to manage their CV health condition.
This project will look to improve standards of care for diabetic patients by evaluating a program that supports participants in making healthy lifestyle changes. The program consists of 13 educational sessions that contain information about the prevention and care of diabetes and cardiovascular disease, physical activity, nutrition, community health and emotional well being.
Milk is the source of high-quality protein, calcium, and other vitamins and minerals. Epidemiologic studies have linked high consumption of milk with risk of metabolic syndrome, T2DM, hypertension and obesity, which are independent risk factors of cardiovascular disease. However, milk contains disaccharide lactose, which may cause gastrointestinal problems in those adults with poor digestion. Recent studies have shown that subjects with intolerance to lactose tend to reduce their consumption of milk. Actually, consumption of 12g lactose (240ml milk) per day produces negligible symptoms in lactose intolerant. Furthermore, a dairy-rich diet could improve lactose intolerance because of colonic adaption to it. Lactose maldigestion would not be a restricting factor in milk intake. In general, the undigested lactose will be fermented by colonic bacteria into hydrogen, carbon dioxide, and short-chain fatty acids (SCFA: acetate, propionate, and butyrate). The SCFAs may have beneficial effects on human glucose and lipid metabolism, and the lactose fermentation may change the intestinal flora profile. But there are few studies evaluating effect of milk intake on health of people with lactose malabsorption or intolerance.This trial intend to study the effect of whole milk on cardio-metabolic risk factors of healthy person with or without lactose maldigestion.
The aims of the study are twofold. In the cross-sectional approach (Part I), the study will be conducted in an older population to assess the association of physical fitness on different parts of the human vascular bed. In the interventional approach (Part II), it aims to investigate whether and to what extent advanced vascular ageing (AVA) in older subjects with increased cardiovascular risk can be reversed by regular walking- based high intensity interval training.
