Filter by:In this exploratory study, we hope to learn if treatment of broadband light with infrared light can alter the molecular pathways associated with aging. Secondary exploratory objective is to see if there are any visible effects of this light treatment on human skin.
The ACHIEVE study will be a randomized controlled trial nested within the infrastructure of the Atherosclerosis Risk in Communities (ARIC) study. We plan to enroll 850 70-84 year-old cognitively normal older adults with hearing loss, who will be randomized 1:1 to the hearing intervention (hearing needs assessment, fitting of hearing devices, education/counseling) or successful aging health education intervention (individual sessions with a health educator covering healthy aging topics). Post-baseline, participants will be followed semi-annually for 3 years.
An optimal nutritional status is essential for healthy ageing. Telemonitoring might contribute to maintaining or improving nutritional status in elderly people.The objectives of this effect study are to test the feasibility and effectiveness of telemonitoring of nutritional parameters in community-dwelling older adults.
This study aims to look at whether human umbilical cord blood plasma (HUCBP) is safe for intravascular (iv) administration; and whether it provides any reversal of frailty or other age-related biological measures.
The study will provide insight into how lifestyle-related interventions, specifically nutrition and exercise can impact the health of older women. The study uses a unique combination of interventions and encapsulates overall health outcomes by measuring both mobility and cognitive function. The study examines the effects of a combined omega-3 polyunsaturated fatty acid (PUFA) and multi-nutrient supplement on measures of mobility and cognition in women aged 60 years and above. Volunteers for the study will be randomly assigned to one of four groups which are as follows: - Omega-3 PUFA multi-nutrient supplement and aerobic exercise - Omega-3 PUFA multi-nutrient supplement and no exercise - Placebo supplement and aerobic exercise - Placebo supplement and no exercise Volunteers undertake the dietary supplementation for a period of 24 weeks. The active dietary supplement contains a daily dosage of 1 g docosahexaenoic acid, 160 mg eicosapentaenoic acid, 240 mg Ginkgo biloba, 60 mg phosphatidylserine, 20 mg d-α tocopherol, 1 mg folic acid, and 20 µg vitamin B12. The placebo supplement contains an iso-calorific oil blend that is typical of the current UK diet. The aerobic exercise consists of two classes per week the final 12 weeks of the study on stationary spinning exercise bikes. Volunteers attend testing at the beginning and after 24 weeks. Verbal memory, spatial working memory, executive function and processing speed are assessed via a battery of cognitive tests. Mobility testing comprises three walking tests, some under single and dual task paradigms, as well as the five times sit to stand test, a measure of dynamic balance and functional mobility. Volunteers also provide two blood samples, one for fatty acids analysis and the other serum homocysteine levels. Participants also complete health-related quality of life questionnaire, the short form 36 (SF36) questionnaire, food diary and food frequency questionnaire.
This project is focused on the gap in understanding of bilateral brain interactions and their role in helping normative and clinical elderly populations maintain cognitive health. The investigator will focus on investigating this neural mechanism of these interactions and promoting them with a precise application of TMS, in order to test the hypothesis that excitatory interactions between the hemispheres can provide positive outcomes for patients with pre-clinical AD (amnestic Mild Cognitive Impairment or MCI-AD). In Session 1, the investigator will establish the spatial specificity of bilateral brain mechanisms with combination of behavior, TMS, and structural neuroimaging in cortical sites known to be active during memory encoding. In Session 2, the investigator will establish the underlying dynamics of interhemispheric communication using a novel combination of TMS and electroencephalography (EEG) to establish the coordinated activity between the hemispheres; Lastly, in Session 3, the investigator will use the TMS entraining parameters delineated in Aim 2 to promote specific cross-hemispheric communication, applied to participants performing a Picture Encoding task, a general task of memory performance. The outcome of these studies will allow our group to evaluate the strength of this brain stimulation protocol in alleviating age-related and dementia-related cognitive decline, and enable development of novel treatment protocols for dementia in elderly cohorts.
An optimal nutritional status is essential for healthy ageing. Telemonitoring might contribute to maintaining or improving nutritional status in elderly people.The objectives of this pilot study are to test the feasibility, acceptability and implementation fidelity of telemonitoring of nutritional parameters in community-dwelling older adults; to test the study procedures for effect evaluation; and to determine the likelihood of achieving desired impact on the primary and secondary outcomes.
Life expectancy and elderly population are increasing. Health professionals try to provide longevity with good quality of life for this population, through the functional independence maintenance. In this context, physical exercise has an important role, specially the strength training. The ability to produce muscle strength is positively associated with the functionality and independence of older people. Different types of strength training can lead to different neuromuscular and functional gains. These types of interventions can help health professionals to determine characteristics of training for the elderly, aiming the maintenance of their functional independence. Thus, the purpose of this study is to determine the effects of a concentric strength training versus a concentric-eccentric strength training for knee flexors and extensors on structural, neuromuscular and functional parameters in older people, as well as to investigate the effect of a detraining period. Additionally, the investigators will try to identify which structural and neuromuscular parameters of lower limbs are better related to the functionality.
The tDCS & Dual Tasking study will compare the effects of transcranial Direct Current Stimulation (tDCS) targeting three different cortical regions (as well as sham stimulation) on dual task standing and walking in older adults with and without a recent history of recurrent falls.
The purpose of this study is to observe whether the transplantation of autologous stromal vascular fraction (SVF) in adipose tissue is safe and its effect on improving skin regeneration.
