Filter by:The Hypertension Canada Clinical Practice Guidelines for blood pressure measurement using AOBP recommend against any wait time prior to commencing the measurement. The recent AHA guidelines however call for a 5-minute rest first. In uncontrolled hypertension, AOBP is typically higher than the daytime readings from ambulatory blood pressure monitoring (ABPM), but this is not the case for patients with controlled hypertension.
The purpose of the research is to assess the impact of co-consuming plant sterols-enriched food product as part of a healthy eating pattern diet on endothelial function (brachial artery FMD, vasodilation-related and vasoconstriction-related biomarkers) and blood pressure management (24-hour ambulatory and classic blood pressure) in Singapore individuals with MetS.
This study, "Fitness Intensive Therapy (Get FIT) to Promote Healthy Living in Older Adults", will test a mobile-health based intervention which includes use of a Fitbit activity tracker for 3 months, a smartphone application that tracks daily food intake, and one 45 minute counseling session to create personal goals and provide patient education by a health coach; versus Get FIT+ (the same items) plus personalized text messages focusing on participant's activity and nutrition progress as monitored in the app, from the health coach for 3 months. The investigators will measure the impact on participant's diet, physical activity, clinical outcomes, psychosocial well-being, and engagement.
This study aims to investigate the impact of replacing meat consumption with plant-based meat alternative consumption on cardiovascular health, the gut microbiome, and metabolic status.
The primary prevention of cardiovascular disease is an unresolved health problem. A sedentary lifestyle and a low cardiorespiratory condition both increase the risk of cardiovascular disease, at a similar extent as that promoted by traditional risk factors, such as smoking, high blood pressure or dyslipidemia. The scientific evidence regarding the effect of the promotion of an active lifestyle on primary cardiovascular prevention is limited. Several studies have shown that structured training programs (TP) are effective at short term, but at the medium or long term their efficacy is still unknown. There are very few randomized controlled trials, and there are almost no studies conducted in the primary care setting which analyze the long-term effects of this type of program on primary cardiovascular prevention. The investigators performed in primary care a previous quasi-experimental study without control group demonstrating the short-term effectiveness in the improvements of both physical condition and in the practice of physical exercise of this TP, the shortest so far analyzed in primary care. With the current study the investigators also want to demonstrate its short-term efficacy in the promotion of moderate-high physical activity and in the practice of physical exercise, through a high-evidence design such as a randomized clinical trial with a control group, also the extension of such efficacy in the medium and long term. Objective: To determine the efficacy of a supervised 2 month TP on short-term (1 month post-TP), medium-term (6 months post-TP) and long-term (12 months post-TP) promotion of moderate-high physical activity and practice of physical exercise, in a sedentary population with high cardiovascular risk, attending primary care centres. Methodology: A parallel, randomized, intervention study, with a control group. Inclusion criteria: Men and women of an age between 35 and 70 years, attending a primary care center in hospital reference area, with high cardiovascular risk. Sedentary lifestyle defined by a score <2 in the brief Physical Activity Questionnaire for care consultations primary adapted to measure the frequency of physical exercise and with a total result in the International Physical Activity Questionnaire (IPAQ)-long version ≤1500 METs x minutes/week, who agree to participate and commit to compliance with the program. Participants were randomized (automated list generation) to a control group, consisting in conventional management or to an intervention group (TP 2 months, 3 times / week). Both groups received an educational talk about cardiovascular risk, healthy diet habits and cardio-healthy exercise at the beginning of TP. Assessments were performed at baseline, and at 3, 8 and 14 months. OUTCOMES: 1. Main outcome measure: differences between groups in the proportion of participants with an "Effective response in Physical Activity ". This effective response was considered if there was an increase ≥ 240 METs x minutes / week in the moderate-high physical activity (measured by IPAQ-long version) in the final evaluation. 2. Secondary outcome variables: differences between groups in the change in: 1. Physical exercise: quantitatively (measured by the sum of the results obtained in items 22-25 of the IPAQ-long version), frequency (Physical Activity Questionnaire for care consultations primary adapted to measure the frequency of physical exercise), and intention (Questionnaire of Stages of Change of Exercise (QSCE)-Short Form). 2. Global physical activity (measured with the total result in the IPAQ-long version). 3. Physical condition: ergometric variables (Peak Oxygen Consumption, exercise duration, anaerobic threshold moment)) and 6 Minute Walk Test. 3. Other efficacy and safety variables: differences between groups in the changes in: 1. Anthropometric variables. 2. Blood pressure. 3. Biochemical parameters. 4. Mediterranean diet (simplified version of the questionnaire ¨Adherence to the Mediterranean Diet¨). 5. Quality of life (questionnaire SF36-long version). 6. Mood (Beck depression index).
The need for new models of integrated care that can improve the efficiency of healthcare and reduce the costs are key priorities for health systems across the United States. Treatment costs for patients with at least one chronic medical or cardiovascular condition make up over 4-trillion dollars in spending on healthcare, with estimations of a population prevalence of 100-million affected individuals within the next decade. Therefore, the management of chronic conditions requires innovative and new implementation methods that improve outcomes, reduce costs, and increase healthcare efficiencies. Digital health, the use of mobile computing and communication technologies as an integral new models of care is seen as one potential solution. Despite the potential applications, there is limited data to support that new technologies improve healthcare outcomes. To do so requires; 1) robust methods to determine the impact of new technologies on healthcare outcomes and costs; and 2) evaluative mechanisms for how new devices are integrated into patient care. In this regard, the proposed clinical trial aims to advance the investigator's knowledge and to demonstrate the pragmatic utilization of new technologies within a learning healthcare system providing services to high-risk patient populations.
Cardiometabolic disorders are a leading cause of death worldwide. Replacing saturated fatty acids (SFA) with unsaturated fatty acids is recommended as a way of lowering cardiometabolic disease risk. Consuming a diet rich in SFA may lead to a greater metabolic-inflammatory response in white adipose tissue during the fasting state, when compared to eating a diet rich in monounsaturated fatty acids (MUFA). Since individuals spend most of the day in the fed (or postprandial) state, it is important to see how different types of dietary fatty acids affect postprandial white adipose tissue and systemic metabolic-inflammatory responses. This study will investigate the effect of a SFA-rich meal on markers of white adipose tissue and systemic metabolic-inflammation, compared to a MUFA-rich meal in overweight adults. In a randomised, single blind controlled, cross-over manner participants will consume either a SFA- or MUFA-rich meal and sequential blood and white adipose tissue samples will be collected before and until 6 hours postprandially.
The present study will investigate the effect of prior walking on postprandial metabolism and endothelial function in healthy South Asian and White European women. Participants will complete two, 2-day trials in a random, crossover design separated by at least 3 weeks to control for the menstrual cycle phase. On day 1, participants will either rest or complete a 60 minute walk at 60% maximal oxygen uptake. On day 2, participants will arrive at 08:00 having fasted overnight and a baseline venous blood sample and endothelial function measurement will be taken. Participants will consume a high-fat breakfast and lunch and 12 subsequent venous blood samples will be taken throughout the day at standardised intervals to measure a variety of coronary heart disease risk markers. A second endothelial function measurement will be completed 2 hours after the breakfast. Blood pressure will be measured every hour. It is expected that the South Asian participants will have impaired metabolism and endothelial function compared to their European counterparts but the bout of exercise performed on day 1 will mitigate these responses.
This is a single centre, double-blind, randomised, placebo-controlled, parallel staggered group study of BIA 5-1058 in 11 different cohorts of 15 healthy subjects. Subjects will be randomly assigned to receive once-daily oral doses of BIA 5-1058 or matching placebo for 10 days. The primary objectives of the study are to assess the safety and tolerability of BIA 5-1058 after repeated ascending doses under fed and fasted conditions and to assess the pharmacokinetics (PK) of BIA 5-1058 after repeated ascending doses under fed conditions having matching fasting cohorts for comparison of bioavailability. It is planned that comparison cohorts will be dosed in parallel, i.e. Cohorts 1 and 2, 3 and 4, 5 and 6, 7 and 8 and 9 and 10. Cohorts may be split or dosed sequentially for logistical purposes; however, data from both comparison cohorts (e.g. Cohorts 1 and 2) must be available before dose escalation to the next dose levels.
Fluid responsiveness is difficult to assess at the bedside. The accuracy of published techniques to detect preload-dependent patients have many pitfalls and limitations. The present study test the role of noninvasive effective pulmonary blood flow measured by expired carbon dioxide to detect fluid responsivess in mechanically ventilated patients.
