NCT ID: NCT05601713 Completed - Aging Clinical Trials

Mitigating Heat-induced Physiological Strain and Discomfort in Older Adults Via Lower Limb Immersion and Neck Cooling

Start date: September 28, 2022
Phase: N/A
Study type: Interventional

The incidence and severity of hot weather and extreme heat events (heat waves) is increasing. As such, there is an urgent need to develop heat-alleviation strategies that can provide targeted protection for older adults who are at an elevated risk for heat-induced illnesses or death due to impaired body temperature and cardiovascular regulation. While air-conditioning provides the most effective protection from extreme heat, it is inaccessible for many individuals and cannot be used during power outages (e.g., heat-related rolling blackouts). Immersion of the lower limbs in cold water and/or the application of cold towels to the neck have been recommended as simple and sustainable alternatives to air-conditioning. However, empirical data to support the efficacy of these interventions for mitigating physiological strain and discomfort in older adults is lacking. To address this knowledge gap, this randomized crossover trial will evaluate the effect of lower limb immersion with and without application of cold towels to the neck on body core temperature, cardiovascular strain and autonomic function, dehydration, and thermal comfort in adults aged 65-85 years exposed to simulated heat wave conditions (38°C, 35% relative humidity) for 6 hours.

NCT ID: NCT05601102 Completed - Quality of Life Clinical Trials

danceSing Care Evaluation: Testing the Effectiveness

Start date: March 20, 2023
Phase: N/A
Study type: Interventional

This pilot randomised controlled trial aims to compare the effectiveness of a 12-week music and movement intervention in older adults in care homes compared to a waitlist control group. The main questions it aims to answer are: - Do salivary cortisol and DHEAS levels improve after the intervention, compared to the waitlist control group? - Do feelings of anxiety and depression improve after the intervention, compared to the waitlist control group? - Does the quality of life improve after the intervention, compared to the waitlist control group? - Does physical function improve after the intervention, compared to the waitlist control group? Participants will engage in music and movement sessions three times per week for 12 weeks. Researchers will compare the intervention group to the waitlist control group to see if any effects occur.

NCT ID: NCT05593939 Completed - Aging Clinical Trials

Slow Age: Interventions to Slow Aging in Humans

SlowAge
Start date: May 1, 2022
Phase: Phase 2
Study type: Interventional

The proportion of older individuals is growing, and it is therefore important to investigate ways to promote healthy aging. Exercise is one of the most studied interventions and is known to have a variety of health benefits. Dietary interventions have also shown encouraging results, with intermittent fasting being a promising anti-aging intervention. Likewise, dietary supplementation with precursors that can increase the central metabolite nicotinamide dinucleotide (NAD+) has powerful effects on aging at least in model organisms. Although physical exercise is known to increase health-span, the effects of these latter dietary interventions on aging lacks evidence in humans. This is a randomized, controlled trial of interventions to slow aging in humans. Healthy older individuals will be randomized into either an aerobic exercise (EXE), time-restricted feeding (TRF), nicotinamide riboside (NR), or control group and followed for twelve weeks. Changes in biomarkers of aging will be assessed before and after the intervention. It is hypothesized that the interventions provide similar, superior benefits to these markers when compared to placebo. Primary Outcome: Interleukin-6 levels. Secondary Outcomes: CRP, TNF-α, NAD+, hematologic age, epigenetic age (DNA methylation), transcriptomic age (RNA-sequencing), functional age (handgrip strength, gait speed), body composition, vocal age, and photo age

NCT ID: NCT05585762 Completed - Aging Clinical Trials

Buck Institute Ketone Ester RCT

BIKE
Start date: November 28, 2022
Phase: N/A
Study type: Interventional

This study is to investigate the tolerability and safety of a ketone promoting ingredient, called a ketone ester (KE), in healthy older adults. This randomized, double-blind, placebo-controlled trial aims to characterize the tolerability and safety of daily consumption of the KE in healthy older adults (over 65 years old) over 12 weeks. Study participants will complete Beverage Tolerability Questionaires (BTQ) to rate any side side effects throughout the study. Safety will also be assessed by collection of blood and urine samples, vital signs, body weight, and monitoring of adverse events (AEs). The study will also collect pilot data to explore possible effects of KE on physical function, cognitive function and quality of life. The findings of this study will be used to facilitate future mechanistic studies of KE in aging.

NCT ID: NCT05559203 Completed - Aging Clinical Trials

danceSing Care Evaluation: Testing the Feasibility

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

- The investigators wanted to find out if digital music and movement resources could be delivered in care homes. They rolled out a 12-week programme to 10 care homes and had 47 care home residents participate in the research. - The investigators also wanted to find out under what circumstances the digital music and movement resources would be most effective for the health and wellbeing of the care home residents. - A survey measuring the number of falls in the past three months, activities of daily living and health, psychosocial wellbeing (anxiety, depression, stress and loneliness), sleep satisfaction and frailty measures such as appetite and weight loss) was completed before and after the intervention. Also, interviews with residents and focus groups with staff were done after the intervention to find out how they felt about the programme.

NCT ID: NCT05544201 Completed - Alzheimer Disease Clinical Trials

Transcranial Alternating Current Stimulation (TACS) for Sleep Disturbances in Neurocognitive Disorders Due to Alzheimer's Disease

Start date: October 1, 2022
Phase: N/A
Study type: Interventional

Background: Sleep disturbances are highly prevalent in ageing population and patients with age-related neurodegenerative diseases, which severely affect cognition and even lead to accumulated amyloid-β (Aβ). At present, non-pharmacological interventions for sleep disturbances in dementia patients are accepted as first line of treatment, of which the evidence from clinical trials is very limited. Encouraging results from recent studies on transcranial direct current stimulation (tDCS) showed moderate positive effects on sleep quality in preclinical Alzheimer's disease (AD). Compared to tDCS, high-definition transcranial alternating current stimulation (HD-tACS) enables the entrainment of neuronal activities with optimized focality through injecting small electric current with a specific frequency and has significant enhancement effects on slow wave activities. Objectives: The investigators aim to 1) investigate and compare the safety, efficacy and sustainability of 40 Hz HD-tACS and HD-tDCS over left dorsolateral prefrontal cortex (DLPFC) in mild neurocognitive disorder due to AD (NCD-AD) patients with sleep disturbances; 2) examine the relationship between the changes in sleep quality, cognitive function and saliva Aβ levels. Methods: Chinese right-handed mild NCD-AD patients with sleep disturbances (aged from 60 to 90 years) will be randomly assigned to a 4-week intervention of either HD-tACS, HD-tDCS, or sham HD-tCS, with 33 participants per arm. Before intervention, structural magnetic resonance imaging (MRI) data is used to construct individual realistic head model. Comprehensive assessments, including sleep quality, cognitive performance and saliva Aβ levels will be conducted at baseline, 4th week, 8th week, 12th week and 24th week. Program adherence and adverse effects will be monitored throughout intervention. Data analysis: The primary outcomes will be the changes in sleep quality and memory performance with modality-driven paradigms (HD-tACS, HD-tDCS, sham HD-tCS), and comparisons of group differences across different time points. Secondary outcomes will be the changes objective sleep pattern, global cognition, saliva Aβ levels and quality of life. Intention-to-treat analysis will be carried out. Changes of efficacy indicators from baseline to each follow up point will be tested with mixed effect model. Significance: This study aims to investigate the feasibility, safety and efficacy of HD-tACS and HD-tDCS over left DLPFC for sleep disturbances and cognitive dysfunction in mild NCD-AD patients. It wills also test the program adherence, tolerability and adverse effects of this innovative neurotechonology. Information will be helpful for in-depth understanding the relationship of "sleep disturbances-amyloid deposition" and guiding the further studies of sleep medicine and neurodegenerative diseases.

NCT ID: NCT05484661 Completed - Aging Clinical Trials

Mechanisms to Reduce Mental and Physical Fatigue Following Exercise Training in Older Adults

BCAA
Start date: December 22, 2022
Phase: N/A
Study type: Interventional

Fatigue is a strong predictor of negative health outcomes in older adults. The research in this study will compared the effects of 8-weeks of branched chain amino acids (BCAAs: dietary supplements commonly taken to improve muscle growth and exercise performance) added to exercise on fatigue compared to exercise with a placebo (an inactive, harmless substance). BCAAs could have an impact on improving fatigue common in older adults, especially when exercising.

NCT ID: NCT05456971 Completed - Aging Clinical Trials

Evaluation of the Long Term Efficacy and Tolerability of ART FILLER® Volume and Lips

AF2
Start date: September 12, 2016
Phase: N/A
Study type: Interventional

The function of injectable fillers for the treatment of dermal contour deformities is to smooth dermal depressions formed by the loss of volume. These fillers (also known as soft tissue augmentation devices) can restore the age-related volume loss of the face, balance the disproportions or correct topographical anomalies. Art Filler® Volume and Art Filler Lips are two hyaluronic-based fillers. Both contain 0.3% lidocaine hydrochloride for its anaesthetic properties. The difference between the two devices lies in their viscosity, which must be adapted for the regions being treated and to restoring facial volumes. Midface for Art Filler® Volume and Lips for Art filler® Lips. On this background, a study is conducted to evaluate the long term efficacy and tolerability of Art Filler® Volume and Art Filler® Lips. It is a prospective, non-comparative, multicentre study with long term evaluation (18 months) of the tolerability and assessment of the efficacy of two devices containing hyaluronic acid intended for filling of lines and restoring volume to the face and lips.

NCT ID: NCT05436392 Completed - Surgery Clinical Trials

De-adopting Routine Preoperative Benzodiazepines for Older Surgical Patients

DROP-Benzo
Start date: August 8, 2022
Phase: N/A
Study type: Interventional

Over 21 million surgical procedures take place among adults aged 65 and older in the US each year, and most older surgical patients in the US now receive benzodiazepines (e.g., midazolam, lorazepam) during anesthesia care. This occurs despite recommendations to avoid these medications in older patients due to associated medical risks and lack of demonstrated benefit. In other words, routine benzodiazepine administration to older surgical patients is likely to represent low-value care that is a suitable target for de-adoption. In this study, we will evaluate a United States Anesthesia Partners (USAP, Dallas, TX) quality improvement initiative using peer comparison feedback to clinicians and/or mailed informational letters to patients as strategies to encourage physician de-adoption of routine preoperative benzodiazepine administration to older surgical patients. In partnership with USAP, this study will be conducted using randomization to evaluate its effect.
