Filter by:The main purpose of this study is to evaluate the effects of an acute dose of dietary nitrate in the form of beetroot juice on skeletal muscle blood flow in response to dynamic knee extension exercise in healthy older adults. All subjects will receive active (rich in dietary nitrate) or placebo (devoid of nitrate) supplementation.
The JADE wRAP™, a wrist worn cuff to measure blood pressure and its supporting software platform is currently at the final alpha prototype stage of development and is not intended for sale. There are minimal risks with using the JADE wRAP™ device; however, the likelihood of these risks has been reduced through design limitations on electrical power delivered to the device and of the pressure delivered to the cuff portion. Patients should experience little to no discomfort from the inflation of the JADE wRAP™ cuff.
Management of acutely elevated blood pressure during the early phase of ischemic stroke remains controversial. In patients treated with IV-tPA, the risk of ICH is closely related to the BP levels. However, intensive reduction of BP carries a theoretical risk of clinical deterioration by inducing cerebral hypoperfusion. Assessment of cerebral perfusion before and after BP reduction is one of the most scientific method to evaluate the safety (and potential benefits) of BP management in the acute phase of stroke. This project will impact practices and delivery of BP management during the acute phase of ischemic stroke. The findings would aid in designing phase 3 clinical trials will track clinical indicators, including the impact on functional outcomes as well as quality-of-life and cost-effectiveness.
The present study aimed at investigating the effects of two different resistance training protocols — nonperiodized (NP) and daily undulating periodization (DUP) — on hemodynamic, morphofunctional and cognitive parameters of robust older women. Methods: Forty-two older women were randomized allocated into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic, morphofunctional and cognitive parameters occurred before, during and after six months. The exercise groups performed the program of exercise twice a week over 22 weeks. In NP, the two weekly sessions were based on 3 sets of 8-10 repetitions at a difficult intensity. However, in DUP, a power exercise session based on 3 sets of 8-10 repetitions at a moderate intensity was added in the first session of the week.
The aim of this research project is to find out whether a personalized definition of the lower blood pressure threshold based on the individual blood pressure profile by means of preoperative 24-hour blood pressure measurement can reduce organ damage (brain, kidney, heart) through reduced blood flow during surgery.
The present study is aimed to investigate whether oral L-arginine supplementation reduces the adverse cardiovascular effects of exposure to traffic-related air pollution among a group of non-smoking adults with elevated blood pressure.
In this research study we want to learn more about using non-invasive tools as a way to predict whether or not a child under general anesthesia will require and respond to fluid administration. It is important for an anesthesiologist to know if a child would respond to fluid administration so that they can provide the optimal intervention for low blood pressure and avoid unnecessary treatment.
Movement is important for overall health. Lack of movement has been shown to be associated with numerous diseases. This study will assess the validity and usefulness of two innovative low risk, non-invasive wellness devices, the Gentle Jogger® and the Gentle Jumper that passively simulate the physical activities of jogging and jumping, respectively. The study will evaluate whether or not each of the devices in different body postures (seated, lying down, slight recumbent and slight head down) produces changes in blood pressure, and indices of dilatation of blood vessels, in a younger (25-59yr) and older (> 60 yrs.) subject population. Volunteers will be paid for their participation in the study. A substudy of this larger study ( Effects of Gentle Jogger on blood pressure), will determine the effects of 30 min of gentle jogger in seated and supine posture compared to Sham
The CIRCUS study is a randomised controlled, cross-over trial to evaluate the effects of increased intakes of citrus fruits and cruciferous vegetables on vascular function in 36 untreated, prehypertensive participants.
A wristband device intended for use as a standalone device, designed for the measurement of intermittent blood pressure, as well as other physiological signals. The device is intended to be worn in day to day life by individuals suffering from hypertension or other conditions where monitoring of blood pressure is of importance.
