Filter by: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.
The number of persons aged ≥60 years in the United States is expected to nearly double, from 57 to 109 million between 2010 and 2050. These demographic changes will have profound implications for the healthcare system because advanced age is associated with a heightened risk of negative health outcomes, including disability and frailty. Few therapeutic strategies currently exist to combat the age-related decline in physical functioning that stems from the progressive loss of muscle mass and strength. The goal of the proposed experiments is to determine the benefits of home-based leg heat therapy (HT) in old, sedentary individuals. This novel approach consists of trousers and a portable water pump. Hot water is circulated through the trousers, evenly heating the buttocks, thighs and calf. We propose to conduct a pilot randomized, sham-controlled trial in 20 sedentary, old individuals to establish the effect of daily home-based leg HT for 12 weeks on skeletal muscle size and function, walking performance and perceived quality of life. Participants will be asked to apply the treatment daily for 90 min using water-circulating trousers perfused with water heated to 42ºC (HT group, n=10) or 33ºC (sham group, n=10). The primary study outcomes is the change from baseline in 6-minute walk distance at 12-week follow up. Secondary outcomes include changes in calf muscle strength, as assessed using isokinetic dynamometry , sit-to-stand time, and calf muscle cross-sectional area, fat content and bioenergetics.
Prescribing of potentially unsafe medications for older adults is extremely common; benzodiazepines and sedative hypnotics are, for example, key drug classes frequently implicated in adverse health consequences for vulnerable older adults, such as confusion or sedation, leading to hospitalizations, falls, and fractures. Fortunately, most of these consequences are preventable. Physicians' lack of awareness of alternatives, ambiguous practice guidelines, and perceived pressure from patients or caregivers are among the reasons why these drugs are used more than might be optimal. Reducing inappropriate use of these drugs may be achieved through decision support tools for providers that are embedded in electronic health record (EHR) systems. While EHR strategies are widely used to support the informational needs of providers, these tools have demonstrated only modest effectiveness at improving prescribing. The effectiveness of these tools could be enhanced by leveraging principles of behavioral economics and related sciences.
SRW Laboratories has formulated the Cel System protocol, a group of three formulas designed to interact with each of the 9 Hallmarks of Aging and combined this with an App that supports positive lifestyle changes, with a view that, if we can positively impact each Hallmark, we can support healthy aging.
The ACHIEVE Brain Health Follow-Up Study is a 3-year follow-up to the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) randomized study to determine the long-term effect of hearing intervention vs. successful aging/delayed hearing intervention on rates of cognitive decline and incident mild cognitive impairment or dementia.
In long-term care, staff provide help to residents with bathing, dressing, eating, walking, toileting, transferring, and moving in bed. Some residents can do more for themselves than others. This study will compare two groups of residents who require the same level of help from staff. Over eight weeks, one group will receive occupational therapy services provided by OT students and the other group will not. After the eight weeks, the level of help that each group of people requires will be looked at to see if there are any differences.
This study has two phases: Phase 1 is to examine blood pressure, microvascular function, and sympathetic nerve activity in mid-life adult binge drinkers vs. alcohol abstainers/moderate drinkers. Phase 2 is to examine the effect of 8-week aerobic exercise training on blood pressure, microvascular function, and sympathetic nerve activity in mid-life adult binge drinkers
This is a prospective, single-arm study designed to understand the mechanisms that lead to a loss of response to influenza vaccine in older adults. The investigators will recruit and longitudinally follow a cohort of 66 older adults (65 years and older) who will receive three different influenza vaccines over three annual influenza seasons. Blood samples will be collected from the participants at each of the sixteen study visits over three years. Nasal swab and stool samples will also be collected from participants at seven time-points across the study period. The study is not designed to assess safety or tolerability of the influenza vaccines administered as part of this study.
The COcoa Supplement and Multivitamin Outcomes Study (COSMOS; NCT02422745) is a randomized clinical trial of cocoa extract supplement (containing a total of 500 mg/d flavanols, including 80 mg. (-)-epicatechins), and a standard multivitamin supplement to reduce the risk of cardiovascular disease and cancer among men aged 60 years and older and women aged 65 years and older. This ancillary study is being conducted among participants in COSMOS and will examine whether the cocoa extract supplement or the multivitamin supplement has an anti-aging effect (epigenetic aging and inflammaging) and examining these findings in the context of CVD risk factors and outcomes.
Malnutrition and inappropriate prescribing of renally excreted drugs are common among older persons and are associated with severe consequences such as complicated courses of treatment, mortality, and reduced quality of life. The overall purpose of CanPan is to optimize treatment of older persons with malnutrition with a focus on appetite stimulation and optimized prescribing of renal risk drugs. The CanPan trial consists of two sub-studies. Substudy 1 will provide knowledge on appetite and appetite stimulation and together, sub study 1 and 2 will offer unique knowledge on how body composition, renal function and biomarkers of organ function influence pharmacokinetics for a highly lipophilic (Sativex®) and hydrophilic (Hexamycin®) drug in older medical patients with malnutrition.
