With the increasing regularity and intensity of hot weather and heat waves, there is an urgent need to develop heat-alleviation strategies able to provide targeted protection for heat-vulnerable older adults. While air-conditioning provides the most effective protection from extreme heat, it is inaccessible for many individuals. Air-conditioning is also energy intensive, which can strain the electrical grid and, depending on the source of electricity generation, contribute to increasing green house gas emissions. For these reasons, recent guidance has advocated the use of electric fans as a simple and sustainable alternative to air-conditioning. To date, however, only one study has assessed the efficacy of fan use in older adults and demonstrated that fans accelerate increases in body temperature and heart rate in a short-duration (~2 hours) resting exposure to 42°C with increasing ambient humidity from 30-70%. While subsequent modelling has suggested that fans can improve heat loss via sweat evaporation in healthy older adults at air temperatures up to 38°C, there is currently no empirical data to support these claims. Further, that work assumed older adults were seated in front of a pedestal fan generating an airflow of 3·5-4·5 m/s at the front of the body. This airflow cannot be attained by most marketed pedestal fans. Studies are therefore needed to evaluate the efficacy of fans for preventing hyperthermia and the associated physiological burden in older adults in air temperatures below 38°C and determine whether the cooling effect of fans, if any, is evident at lower rates of airflow. To address these knowledge gaps, this randomized crossover trial will evaluate body core temperature, cardiovascular strain, dehydration, and thermal comfort in adults aged 65-85 years exposed for 8 hours to conditions experienced during hot weather and heat waves in North America simulated using a climate chamber (36°C, 45% relative humidity). Each participant will complete three randomized exposures that will differ only in the airflow generated at the front of the body via an electric pedestal fan: no airflow (control), low airflow (~2 m/s), and high airflow (~4 m/s). While participants will spend most of the 8-hour exposure seated in front of the fan, they will also complete 4 x 10 min periods of 'activities of daily living' (~2-2.5 METS, light stepping) at ~2 hour intervals to more accurately reflect activity patterns in the home.
This study investigated the efficacy of the Silvia program, a mobile-based multidomain intervention, to improve cognitive function and health-related outcomes of older adults with a high risk of dementia. We compare its effects to a conventional paper-based multidomain program on various health indicators related to risk factors of dementia.
COMBI is a multi-center, randomized controlled trial among 70 older adults at risk of cognitive decline. The main goal is to investigate the effect of a 6-week colon-delivered multivitamin supplementation on the gut-brain axis in older adults, by assessing changes in brain function as well as intestinal changes compared to placebo.
This is a small-scale multi-site pilot of a supplemental enhancement called "Care Partner" to the evidence-based CAPABLE program that will involve up to 60 individuals (30 care partners and older adult dyads) and 30 professional staff in organizations currently licensed to provide CAPABLE. This is a qualitative study of a convenience sample of individuals.
The current research project aims to investigate the interaction of cardiorespiratory fitness (CRF) and the ApoE genotype with neurocognitive functions.
The goal of this intervention is to determine the efficacy of coconut sap powder (CSP) to lower arterial stiffness and blood pressure in middle-aged and older adults. Participants will be randomized to the CSP arm or Placebo arm of the study. Primary endpoints include: aortic stiffness assessed by carotid-femoral pulse wave velocity, resting brachial and (non-invasive) carotid blood pressure, and carotid stiffness (e.g. Beta stiffness index, Carotid compliance, Elastic modulus, Distensibility).
Background: Exercise performance is a key predictor for healthy ageing. Laboratory and clinical data have shown strength of a nerve called the vagus nerve, which is lost during age-related disease processes, determines exercise performance. The investigators describe a study protocol designed to test the hypothesis that stimulation of the ear (where the vagus nerve can be safely stimulated) may improve exercise performance alongside beneficial changes in vagus nerve activity in human volunteers. Methods. 28 healthy participants aged 18-75y will be randomly allocated to electrical ear stimulation or placebo treatment for 30 minutes at the same time of day, for 7 consecutive days. Heart monitoring, exercise bike testing, a simple sit-to-stand test and blood sampling will be performed immediately before the first day's intervention and after the last day's intervention. Participants and investigators will be masked to the treatment allocations and analyses. After a 14-day break, participants will perform the same protocol for the opposite intervention to their first treatment allocation. The primary outcome will be the change in VO2Peak (the best measure of exercise performance) following stimulation or placebo protocol. Secondary outcomes include reduction in heart rate after ending the exercise bike test, reduction from peak heart rate after standing from sitting, beat-to-beat heart rate measures and blood inflammatory marker levels. These outcomes will measure exercise performance and vagus nerve function. Safety and complications of the intervention will also be recorded. The study was approved by the NHS Research Ethics Committee (21/LO/0856). Discussion. This 'first-in-man' study will explore whether non-invasive vagus nerve stimulation safely boosts exercise performance and/or vagus nerve activity using electrical ear stimulation, providing data for a device-based approach that may be broadly generalisable to improving health outcomes.
The NCTF135HA medical device from Laboratoires FILL-MED by FILORGA Company is an injectable solution for the treatment of wrinkles and biorevitalization of injected mature skin using a multi-injection technique with CE marking. It is a viscoelastic injectable solution of 1% hyaluronic acid (10mg/ml), non-crosslinked of non-animal origin, obtained by biofermentation, resorbable, opalescent, sterile and apyrogenic. NCTF135HA is an anti-aging viscoelastic solution for the revitalization and intense hydration of tired or dull skin, the treatment of wrinkles and the redensification of mature or sagging skin. This hyaluronic acid solution is intended to be injected into the superficial dermis to compensate for the loss of moisture. Given the expected impact of the injection procedure of the biorevitalization solution on wrinkles, the primary endpoint was chosen to evaluate the effectiveness of the treatment on wrinkles.
In the current study, we will examine how daily paced breathing affects plasma amyloid beta levels and the rate of learning in older adults. Healthy adults aged 50-70 who meet all eligibility criteria will be invited to this study. Participants will be randomly assigned to one of the two conditions: 1) Daily memory and attention training followed by a paced breathing protocol designed to increase relaxation or 2) Daily memory and attention training followed by a paced breathing protocol to increase alertness. Participants will be asked to complete pre and post intervention cognitive testing online, engage in 10 weeks of daily brain training (starting Week 2) and 9 weeks of paced breathing (starting Week 3) at home. They will also be asked to come in for lab visits on Weeks 2, 7 and 12 to provide blood and urine samples to assess amyloid beta levels and to complete magnetic resonance imaging scans to assess perivascular space volume.
