Filter by:The conduit arteries exhibit a viscoelastic behavior. Visco-elasticity is partially regulated by endothelium and contributes to the optimization of the heart-vessel coupling. Aging or high resting heart rate (HR) could alter visco-elastic properties leading to increase stiffness of the conduit arteries, an independent cardiovascular risk factor, and degradation of heart-vessel coupling. Lowering HR with ivabradine could reduce these effects. The objective of this study is to assess the effect of HR reduction by repeated administration of ivabradine on visco-elastic properties, vascular geometry and function of common carotid artery, and on cardiovascular hemodynamic in healthy subject. The influence of aging on ivabradine effects are studied too. 30 healthy volunteers aged between 25 and 65 years old, with a HR ≥ 70 bpm, will receive ivabradine or placebo during 8 days in a single center, randomized, cross-group, double blinded, placebo-controlled study. Each period of treatment will be separate by 12 to 16 days of wash-out. Each subject will participate in an exploration visit, including evaluation of visco-elastic properties, vascular geometry and function of common carotid artery, and cardiovascular hemodynamic, before and after ivabradine or placebo taking.
Changes in mood and cognition are common in older adulthood. Some studies have suggested that transcranial application of near-infrared (NIR) light may have enhancing effects on cognitive and mood status in young adults and individuals with traumatic brain injury. This effect has not been examined in older adults. This study will involve a randomized sham-controlled trial to learn whether NIR stimulation improves cognition and mood in older adults, relative to sham treated controls.
Although increasing age is associated with declining health and function, there are wide variations between individuals in the ageing process. Some of these differences are explained by differences in lifestyle, but little is known about the determinants of lifestyle in older age. The proposed project will describe influences on health behaviour and lifestyle in older adults. Investigators will undertake a prospective study of community-dwelling older people who use any of the Medicine for Older People Services in Southampton, allowing us to gain obtain important insights into the relationship between health behaviour, lifestyle and health outcomes in older people. Our principal aim is to identify key points on the ageing pathway when interventions may be best targeted to promote health. The findings of this project will underpin the design for a complex intervention to be conducted in the future to improve the health outcomes of older people.
Aging is a long term process, starting early in life, and progressively affecting various functions and organs. Cardiovascular diseases and cognitive impairment are two conditions related to advancing age and sharing common risk factors. The Mona Lisa- PREDOR study is a population-based prospective cohort study carried out to develop risk prediction algorithms aimed at identifying people who are the most likely to develop impaired psychometric and cognitive functioning and impaired cardiovascular risk, in the coming years.
The purpose of this study is to learn more about how to maintain health and independence for seniors by developing tools that collect data constantly from their home. Caregivers can then use this information to make decisions about their health care, such as when an individual may not be able to live independently any longer. Specific Aims of this study are: - Aim 1: To identify trends in our data that predict health decline. To serve this aim, we want to test a number of tools that we have developed, such as in-home sensors, to determine which ones are best at measuring health risks in seniors. After collecting information for one year, we will look at which tools could be most useful to provide feedback to seniors and their communities about the process of aging. - Aim 2: To develop a system for analyzing the data we collect and presenting a summary of the data to care teams. - Aim 3: To validate our data and the computer-based tool in senior community settings.
This project evaluates the effects of piano training and computerized cognitive training on cognitive performance in healthy older adults compared to controls. The project is intended for healthy older adults (60-80 years) with little to no previous musical training (less than three years of prior musical training or cognitive training and not currently engaged in music reading or musical performance, less than 10 hours of previous cognitive training). Investigators anticipate that musical engagement will serve as an enjoyable cognitive intervention for older adults. Investigators believe that piano training will enhance cognitive performance on executive functions essential for maintaining independence in older adulthood. Learning a musical instrument, while challenging, will improve self-efficacy, mood, and qualtiy of life. Participants engaged in piano training will demonstrate reduced cortisol levels and increased immune function responses. Investigators predict that adults enrolled in computerized cognitive training will demonstrate enhanced memory, working memory and self-efficacy post-training.
This protocol addresses: 1) How gene expression changes in bone cells are affected by aging? 2) Is aging associated with decreased signaling between bone cells? 3) How does treatment with the osteoporosis medication denosumab affect bone cell signaling?
The objective of this research is to develop original virtual reality scenarios and/or new virtual reality equipments to evaluate or diagnose pathologies, such as attention deficit disorders or neuropsychiatric pathologies, addiction, anxiety or depression or pathologies interfering with sleep/wake disorders.
The Lake Nona Life Project aims to examine the health and wellness of participants over the course of multiple years, focusing on the links between health and wellness, longevity, quality of life, and human performance.
This proposed prospective study will evaluate whether a novel exercise approach, seated vibration therapy, can improve function in the target population of older adults. Therefore, the primary aim of this pilot is to examine the effect of vibration therapy on muscle function (balance, muscle power and strength) and muscle mass.
