Filter by:The investigators will study performance on computerized cognitive tasks in healthy participants of different ages to gather normative data for newly developed computerized cognitive tests. These tests are designed to permit the early detection of individuals at risk of age-related cognitive decline.
The specific aim of the study will be to set up a perioperative database to longitudinally track the progress of elderly patients undergoing major surgery from the preoperative period to five years postoperatively. This database will form the foundation of a programme that will be sustainable through future grants to implement clinical strategies to improve outcomes.
Evidence from previous studies supports a strong relationship between fruit and vegetable consumption and reduced cardiac risk. This could be mediated via improvements on blood pressure, platelet function and vascular reactivity. Certain vitamins and polyphenols found in fruits and vegetables, have antioxidant and anti-inflammatory effects and play a major role on the function of immune cells. Previous studies have also demonstrated the importance of omega-3 fatty acids on humans' health and their positive effects on the cardiovascular system and blood lipids regulation, as well as their involvement on inflammatory response. Nutritional regimens with adequate intake of micronutrients, fruit and vegetables, omega-3 fatty acids, low in sugar and saturated fats, such as the Mediterranean diet or vegetarian diets, can reduce chronic inflammation and oxidative stress and improve cardiovascular risk profile. Considering that the population's fruit and vegetable and omega-3 intakes are below recommendations, whole food-based supplements could provide an accessible form of supplementation to bridge the gap between actual and recommended intakes. This study is aiming to assess whether long-term separate ingestions of an encapsulated juice powder concentrate and a plant-based omega fatty acid supplement, or a combined ingestion of the two, can affect biomarkers of cardiovascular health, low-grade inflammation and indicators of biological aging in older adults.
The study seeks to investigate whether 24 weeks of power training has neuroprotective effects in older PwMS. Additional purposes are to examine the effects of 24 weeks power training on physical function, cognitive function and neuromuscular function. Further, it is investigated whether the potential effects of power training are maintained after 24 weeks of follow-up.
The ability to mount an effective immune response declines with age, leaving the elderly increasingly susceptible to infectious diseases and cancer. Rapamycin, an FDA approved drug to prevent transplant rejection, increases the lifespan and healthspan of mice and ameliorates age-related declines in immune responsiveness, cancer survival, and cognition in laboratory animals. Investigators are conducting a translational trial to test whether rapamycin also improves life functions in humans focusing on elderly persons (aged 70-95). Substudy E will evaluate the Rapamycin and Cardiac Function.
Exercise tolerance decreases with age and a sedentary lifestyle. Muscle critical power (CP), is a sensitive measure of exercise tolerance that is more even more relevant to and predictive of endurance performance than VO2max. While recent evidence indicates that CP and muscle function decrease with aging, the cause of this decrease in CP and the best way to mitigate the decrease in CP are unknown. This study will: 1. Measure knee extensor CP in young and old individuals and determine the extent to which changes in muscle oxygen delivery (e.g. resistance artery function, maximum exercise blood flow), muscle mass and composition (e.g. whole-muscle size, muscle fiber cross-sectional area) and mitochondrial oxygen consumption (e.g. maximal coupled respiration of permeabilized fibers biopsied from the knee extensors) contribute to the decrease in CP with age. 2. Examine the effectiveness of two different therapies (1. High Intensity Interval Training, HIIT and 2. Muscle Heat Therapy) at improving muscle function and critical power in young and older adults. 3. Examine the impact of muscle disuse (2 weeks of leg immobilization), a potential contributor to the decrease in muscle function with aging, on muscle function and critical power and determine if heat therapy is an effective means of minimizing the impact of disuse on muscle function and critical power.
In this project, the investigators propose to demonstrate the feasibility of remotely-monitored, caregiver (or spouse)-administered, home-based tDCS intervention to improve mobility in ambulatory older adults with recent falls. This is a three-phase feasibility study in older, ambulatory adult participants at risk of falling due to a loss of balance (participant faller, PF) together with a willing and able participant administrator (PA) that is available during weekdays to administer tDCS (transcranial direct current stimulation) to the PF. Phase 1 is focused on the development and refinement of our training materials for home-based tDCS for PF/PA pairs. The objectives of this phase: 1. Identify areas of confusion and challenges for older adults. 2. Refine our training materials to accompany the home-based tDCS system. In Phase 2, the investigators will complete a pilot trial in 12 PF/PA pairs to assess the feasibility of deploying home-based tDCS in larger clinical trials, and to prepare for the development and implementation of such trials. The objectives of this phase: 1. Determine the mean/range number of visits needed for in-person training. 2. Compliance and retention with the study protocol. 3. Safety/side effects of home-based tDCS, as compared to previously established laboratory-based tDCS data. The investigators hypothesize that adult PAs are able to successfully administer home-based tDCS to PFs. The investigators also expect that PF/PA pairs will exhibit excellent adherence to the intervention and that the prevalence and severity of reported tDCS side-effects will be similar to that observed in previous laboratory-based studies. In Phase 3, the investigators will complete a pilot trial in up to 18 PF/PA pairs; i.e., those who have previously successfully completed either Phase 1 or Phase 2. The study objectives/aims for Phase 3 are: 1. Further explore compliance and retention with the study protocol over a longer time period 2. Identify safety/side effects of home-based tDCS over a longer time-period as compared to previously established laboratory-based tDCS interventions. In Phase 3, the investigators hypothesize that adult PA's who have previously demonstrated the ability to successfully administer tDCS at home, will retain competence and compliance with administration over a longer period, up to 1 year.
Taiwan is already an aging society due to the rapid increase of the aging population. To cope with this situation, it is necessary to make preparations for the care of the elderly. World Health Organization (WHO) proposed aging health strategy in recent years, and the community participation is the most important for the elderly. The courses provided by the community empowering are important to promote the healthy life of the elderly. However, at this stage, there are relatively few courses related to cognitive functions, life-style activities and aging education. It is needed to add more courses related to multi-domain.
Frailty is a syndrome in which the accumulation of small, individually insignificant deficits leads to heightened vulnerability to adverse events and predisposes to potential catastrophic decompensation. Objective of this study is to clarify the underlying genetic and immunological mechanisms responsible of frailty condition focused on: i. nephrosclerosis ageing kidney phenotype related to salt effects on immunosystem, ii. immunological aspect of sarcopenia, iii. psychological disorder related to immunosystem activation, iv. detection of new biomarkers of frailty.
The long-term goal of this pragmatic, cluster randomized study is to develop a sustainable program for healthcare systems to reduce fatal and nonfatal falls among high-risk older adults living independently in their communities. This study will examine how a medication care plan, grounded in established medication deprescribing and tapering frameworks, can be implemented in primary care clinics to reduce falls among older adults living in rural Iowa communities. The study is a collaboration between researchers and clinical pharmacists at the University of Iowa and a clinical team from the MercyOneSM Health Network, which is a non-academic healthcare system with significant reach into rural Iowa communities The study's specific goals are as followed: - Aim 1: Examine the effectiveness of a clinic-based, individualized medication care plan in reducing rates of all falls including medically treated falls (sub-aim 1a) and motor vehicle charges and crashes (sub-aim 1b) among older adults seen in rural primary care clinics. - Aim 2: Identify provider and patient factors that are associated with patient adherence to medication deprescribing and discontinuation recommendations. - Aim 3*: Evaluate implementation of the medication care plan to understand its acceptability, usability and relevance among healthcare system administrators, clinics (clinic managers and clinical staff), providers (health coaches, pharmacists, prescribers) and patients. Note*: Only Aims 1 and 2 (i.e., pertinent to the clinical trial) will be described in this clinicaltrials.gov study description. Intervention and control patients will participate in: - Baseline assessment - Quarterly follow-up assessments - Monthly falls tracking Additionally, Intervention participants will receive: • An individualized medication action plan to deprescribe medications that put them at high risk for a fall Researchers will compare intervention and control participants for changes in self-reported fall rates (primary outcome), EMR-indicated medically-treated falls (secondary outcome), traffic-related charges (secondary outcome), and motor vehicle crashes (secondary outcome).
