Filter by:This multicentre two-phased RCT aims to evaluate implementation potential, cost-effectiveness, effectiveness, and the role of exercise intensity of a home-based exercise and physical activity intervention to improve de novo kidney transplant recipients' physical fitness, cardiovascular health, gut microbiome characteristics, and health-related quality of life. The first phase of this study comprehends a six-month exercise training intervention. Patients will be randomized into (i) a sham intervention consisting of low-intensity balance and stretching exercises (LIT), (ii) a moderate-intensity aerobic and strength training intervention (MIT), or (iii) a moderate- and high-intensity aerobic and strength training intervention (MHIT). The second phase of this study comprehends a physical activity maintenance intervention provided to MIT and MHIT but not LIT. A total of 147 de novo kidney transplant recipients will be recruited from two independent Belgian transplant centres i.e. UZ Leuven and UZ Ghent.
This study will test whether potassium supplementation can reduce the deleterious effect of a high sodium diet on blood vessel function, blood pressure reactivity and autonomic nervous system function in apparently healthy adults.
Consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. This shift is driven by environmental and health factors. However, the consequences of such a transition on muscle mass still remains to be explored. This is of particular importance in the older population, where the age-related reduction in muscle mass and strength is highly prevalent. Adequate dietary intake, specifically protein intake, is a well-known strategy in promoting muscle mass in older adults. Plant-based foods are currently considered to be inferior to animal-based foods in their protein quality, and are therefore considered to be suboptimal for the maintenance of muscle mass at an older age. On the other hand, combining plant-based foods may improve the protein quality and thereby the anabolic properties of a vegan meal. Evidence regarding the anabolic properties of vegan diets in older adults is scarce. As such, the current study aims to assess 1) the effects of a 12-week self-composed vegan diet in comparison to an omnivorous diet on thigh muscle volume (TMV) in community-dwelling older adults and 2) the effect of a 12-week self-composed vegan diet combined with twice-weekly resistance exercise (RE) on TMV in comparison to a self-composed vegan diet without resistance exercise in community-dwelling older adults.
The efficacy of the Mindfulness Based Stress Reduction (MBSR) program has been widely researched. However, research on the efficacy of a standardized program, specifically focused on self-compassion skills, such as the Mindful Self-Compassion (MSC) program remains scarce. Moreover, the use of long-term follow-ups and the analysis of regular practice of mindfulness and self-compassion over time to identify possible changes in inflammatory activity and in biomarkers associated with diseases has been even less analysed and represent a gap in this area. In this context, a main hypothesis is proposed: MSC training and the subsequent regular practice will contribute to improve mental health, self-reported health status, psychological wellbeing and health-related biomarkers. This research uses a RCT design to analyse our main hypothesis. Our RCT design includes three conditions, i.e. MSC group compared to a well-established protocol MBSR training group and to a waitlist control group (CG), and four moments of measure, i.e. pre- and post-training, 6-month, and 12-month follow-ups. Participants in the experimental conditions will receive, respectively, the MSC and MBSR 8-week trainings and afterwards they will go on with weekly MSC/MBSR guided practices over a 12-month period. In addition to an analysis of the relative efficacy of MSC compared to MBSR and CG, we will also study the mechanisms involved in the efficacy of MSC training.
The goal of this study is to learn more about how the time in which participants consume their meals relative to their personalized circadian rhythm influences their overall cardiometabolic health and weight. The investigators are hoping to discover if a circadian-based time restricted eating intervention will improve cardiometabolic health and decrease weight. The protocol is a 46 day prospective cohort study that includes both field and in-laboratory data collection in overweight and obese individuals.
A growing body of data shows that the enteral microbiome has an effect on cardiovascular diseases. Exogenous inorganic dietary nitrate mediates cardioprotective effects and has been shown to have an influence on the oral microbiome. The nutritional aspects of these cardioprotective effects are particularly intriguing since nitrate is abundant in our everyday diet. Whether dietary nitrate influences the enteral microbiome and downstream metabolites like short-chain fatty acids (SCFA) and TMAO will be investigated in the present study.
Cardiovascular disease (CVD) claims more lives each year than cancer and chronic respiratory disease combined. Participation in cardiac rehabilitation (CR) reduces mortality and risk of a major cardiovascular event in secondary prevention populations, including older adults. Older adults are less likely to participate in CR, as comorbidities in this population, including arthritis and chronic obstructive pulmonary disease, make participation difficult. Singing is a physical activity that involves components of the vagal nerves manifested as changes in cardiac autonomic regulation. Unlike physical exercise, the effects of singing on cardiovascular health has not been well-studied. The hypothesis for this project is that older patients with CVD will have favorable improvement in cardiovascular biomarkers, including, endothelial function and heart rate variability (HRV), after 30 minutes of singing.
The purpose of this study is to determine whether random assignment to a mentor-mentee relationship is associated with beneficial cardiovascular health effects in both mentors and mentees.
The MyHeart Counts Cardiovascular Health Study will utilize mobile health capabilities of smartphones and wearables to assess daily activity measures of the general population and compare these to measures of cardiovascular health risk factors and fitness. How people divide their time among exercise, sedentary behavior, and sleep all affect cardiovascular health, yet to date these have largely gone unmeasured. With the advancement of phone sensors and wearable fitness tracking devices these factors are now more straightforward to gather and measure. The use of smartphones by a large segment of the population allows for data collection on an unprecedented scale. The investigators aim to amass activity and cardiovascular health data on thousands of participants as well as provide significantly more quantitative data on type,duration, and intensity of daily activities. In the second phase of the MyHeart Counts Cardiovascular Health Study (Randomized Assessment of Physical Activity Prompts In A Large Ambulatory Population) the researchers will conduct a randomized controlled clinical trial of four different physical activity prompts (intervention) and their effect on the level of physical activity in the study population as measured by change in step count.
