Filter by:The project is designed as a large scale, cross-sectional study. The aim of the study is to investigate the association of micro- and macrovascular function with physical fitness and body composition in primary school children.
One hundred participants from a combination of (a) local advertisements and/or (b) those whose details are held on a research database (of previous volunteers indicating willingness to be contacted about future studies) will be sought to volunteer for this study. Written informed consent will be gained following greater than 48 hours for the purpose of reading the Participant Information sheets. The study will then involve two stages (i) recruiting participants for a cross sectional analysis of the relationship between physical activity levels and cardiovascular and cognitive function, and (ii) a longer exercise training study in a subsample of these volunteers (i.e. participants who volunteer to exercise train). Participants for stage 1 will then visit the laboratory in the University on three occasions (over a three week period) to be assessed for body composition, exercise tolerance, current physical activity levels, cognitive function and arterial and cardiac health. Each visit will last for 60 - 90 minutes. Participants will then be provided with an accelerometer to wear for a period of one week in order to assess movement counts and sedentary behaviour. Stage 2 will include only those participants who have volunteered for the exercise training component (approx 60). These participants will then be randomly divided into two groups. Both groups will exercise three times per week for 12 weeks duration. Group 1 will exercise in a traditional manner at a moderate intensity, whilst the second group will exercise at a heavy intensity but in short bursts. Both groups will complete the same amount of work but in two differing modes. Both groups will attend the laboratory twice per week for supervised exercise sessions and also perform one home based 30 minute brisk walk per week. All participants will be re-examined at 12 weeks.
The study aims to systematically investigate the interaction between training modality, ACE genotype and disease in heart patients whom complete a cardiovascular rehabilitation program. This is carried out with the goal to improve the benefit of cardiovascular rehabilitation for the patient by maximising adjustments in muscle structure and function with the intervention. A population of healthy individuals will be recruited who will carry out the same training program, in order to compare the training effects respective to the general population.
Background: People with Williams Syndrome (WS) and supravalvular aortic stenosis (SVAS) have less elasticity in their blood vessels. This is called blood vessel stiffness. Blood vessels may have focal narrowings called stenoses or may just be globally more narrow. Objectives: Researchers want to see how blood vessel differences in people with Williams Syndrome and supravalvular aortic stenosis affect organs in the body including the heart, gut, kidneys, and brain. Eligibility: People ages 3-85 who have WS or SVAS Healthy volunteers ages 3-85 Design: - Participants will have yearly visits for up to 10 years. All participants will be offered the same tests. - Participants will give consent for the study team to review their medical records. If the participant is a child or an adult with WS, a parent or guardian will give the consent. - Participants will visit the NIH where they will have a physical exam and medical history. Based on their health history, participants will undergo a series of imaging tests and measures of blood vessel function over the course of 2-4 days. Tests of cognitive abilites will also be performed. Blood will be drawn and an IV may be placed for specific tests.
The purpose of this project is to build capacity for quality improvement (QI) in small primary care practices across Washington, Oregon and Idaho by improving risk factors for heart attacks such as blood pressure, cholesterol and smoking. The Northwest Coalition for Primary Care Practice Support will assist practices by providing them with a QI coach, creating group learning opportunities, and conducting educational outreach activities. An innovative study design will be used to determine what levels and types of support are most helpful and effective.
The primary goal of proposed investigation is to study the impact of oral glutamine supplementation on muscle mitochondrial and endothelial cell function measured mitochondrial energetics and vascular function using 31P magnetic resonance spectroscopy and optical spectroscopy (MRS/OS) among persons with moderate-severe CKD. The secondary objective is to describe the impact of oral glutamine supplementation on mitochondrial metabolic profile as well as inflammatory and oxidative stress biomarkers among persons with chronic kidney disease.
The purpose of this study is to explore how the End Tidal Carbon Dioxide monitoring via nasal cannula (ETCO2-NC) device may allow for earlier detection of respiratory complications. This device will detect the amount of carbon dioxide exhaled with each breath and may better predict high levels of this than traditional monitoring. This may reduce the number and severity of respiratory issues. A convenience sample of 60 participants either scheduled for continuous flow left ventricular assist device (CF-LVAD) implant or who have been readmitted to an ICU with a CF-LVAD will be recruited and randomized to usual care or usual care plus ETCO2-NC throughout their stay in the ICU.
The purpose of this prospective randomized controlled trial (RCT) is to evaluate the feasibility and usability of a commercial pedometer and web application in a case-managed home-based Cardiovascular disease prevention and rehabilitation program for French-speaking Canadians.
Community Paramedicine @Home (CP@Home) is a novel community paramedicine health assessment program for high users of Emergency Medical Services (EMS). Individuals who have been identified as active callers to EMS, individuals who have called EMS for lift-assists, and direct paramedic referrals are referred into the community paramedicine home visit program. The program will focus on in-home chronic disease management, community health service connections, and EMS usage education. Aside from chronic disease management, aspects of the program include health-related quality of life, social isolation and other social determinants of health. Participants in the program will have up to 3 one-on-one home visits from a community paramedic to ultimately reduce repeat EMS calls and improve their overall health.
The overall objective of the proposed cluster randomized trial is to test whether implementation of protocol-based integrated care will improve CVD risk factors (glycated hemoglobin [HbA1C], systolic blood pressure [SBP], and LDL-cholesterol) over 18 months and reduce major CVD events (non-fatal stroke, non-fatal myocardial infarction, hospitalized heart failure, and CVD mortality) over 3 years among patients with type 2 diabetes and additional CVD risk factors or clinical CVD compared to usual team-based care in community clinics in Xiamen, China.
