Filter by:This study does not involve any particular diagnosis. The goal of this research study is to explore the effects of artificial sunlight (ultraviolet B radiation; UVB) on the skin of young adults versus geriatric adults. Sunlight exerts many effects on the body. There is evidence that in response to ultraviolet B radiation (UVB), which are the burning rays of sunlight, young adult skin responds differently than geriatric skin. In fact, researchers feel that this difference in how the skin reacts to UVB is why skin cancers are found in older skin. Researchers believe that a major difference between young adult and geriatric skin is that young skin has a lot of a protein called insulin-like growth factor-1 (IGF-1), whereas geriatric skin has very little. The current study will test how young adult versus geriatric skin responds to UVB, and if geriatric skin treated with an injection of small amount of IGF-1 drug will then act like young skin.
IMAGISION aims to explore, in a cohort of patients referred for geriatric consultation for neurocognitive evaluation, the contribution of functional neuroimaging (functional MRI and, if possible, high resolution EEG) to geriatric expertise, associated with the performance of a battery of neuropsychological tests in the evaluation of decision-making capacity.
The purpose of this study is to investigate the effect of digital cognitive training in the functionality of older adults with Mild Cognitive Impairment.
This study is following up on previous studies that have demonstrated that geriatric subjects respond different to ultraviolet B (UVB) light than young subjects. The treatment of geriatric skin with dermal rejuvenation therapies (dermabrasion, fractionated laser resurfacing) restores the appropriate UVB response. Ongoing studies have tested the ability of fractionated laser resurfacing (FLR) to assess how long this wounding effect lasts-and have found that this appears to be a durable response which lasts for at least two years. The findings that FLR protects geriatric skin at two years is the impetus for this study. This study is an interventional study to assess if FLR treatment of one forearm of geriatric subjects with multiple actinic keratosis will result in the short-term removal of actinic keratosis, and the long-term decrease in levels of future actinic keratosis and other non-melanoma skin cancers in comparison to the untreated arm. Study length and visit: The first part of the study is completed in 1 day then there are follow up visits at 90 days and every 6 months for 5 years.
The purpose of the study is to determine the feasibility of nutritional interventions designed to help older patients maintain physical function after being in the hospital. We will test the feasibility and effect of nutritional interventions with whey protein, collagen or placebo on functional recovery from hospitalization in community dwelling older adults.
The purpose of this study is to explore the feasibility of delivering anticipatory care planning provided by nurses through a series of home visits. Many people with long-term health conditions can benefit from an anticipatory care plan as it helps them feel more in control of their life and allows them to manage changes in their health and well-being. The purpose of this study is to find out if effect of home visits by specially trained nurses for people aged 70 years and over who have been identified as being 'at risk' of developing frailty would be beneficial. Half of the patients in this study will receive home visits from trained nurses in addition to their usual care. Nurses will work with their GP, other healthcare providers and possibly family caregivers to plan and arrange any additional services that the participants require. The other half of patients in the study will receive usual care.
Aims 1. To determine whether the 4 Mountains test of allocentric (i.e. viewpoint-independent) spatial memory, and tests of memory for a recent experience (e.g. watching a brief video), to diagnose the early stages of Alzheimer's disease. 2. We operationalise this as the ability of these tests to predict whether or not an individual progresses from having some cognitive difficulties (diagnosed as 'mild cognitive impairment' MCI) to subsequently developing Alzheimer's disease up to two years later. 3. To assess whether the ability to diagnose early stages of Alzheimer's disease can be improved by combining the scores from different memory tests, from questionnaires assessing spatial and social aspects of everyday life. 4. To assess whether scores on the spatial memory test are correlated with patients' reports of their everyday spatial memory, using a newly-developed questionnaire. Outcome Measures Primary study objective: To determine the ability of allocentric spatial and episodic memory test performance to predict progression from mild cognitive impairment (MCI) to Alzheimer's disease. Secondary outcome measure 1. To assess to what extent social characteristics of everyday life may impact upon progression from mild cognitive impairment (MCI) to Alzheimer's disease. 2. To correlate allocentric spatial test performance with real-world spatial ability as assessed through a novel spatial questionnaire.
This is a planning project with a clinical trial pilot to prepare for a larger fully powered clinical trial. Goals of this pilot project are: to identify and address any modifications of the games required for adaptation to diminished sensory abilities; to optimize training dosage and test timing of retention of effects; and to test and refine the battery of outcome assessments. Primary outcome assessment are tests of attention distraction (subtest from a Useful Field of View Test). This pilot will explore a number of secondary outcome measures including EEG and functional imaging biomarkers of change, measures of general cognitive improvement and measures of function including a driving simulator task.
Two hallmarks of both healthy aging and age-related disease are 1) memory and navigational deficits, particularly in orienting towards goal locations and planning how to navigate to them, and 2) increased susceptibility to stress and altered regulation of the stress response. However, there are marked individual differences in these age-related changes. The investigators' proposal will help characterize factors that contribute to this variability. Participants will be pseudorandomly assigned to stress-manipulated or control groups. The investigators will give both groups a novel immersive navigation task, validated by the PI in healthy young adults. This paradigm gives participants the opportunity to either (a) flexibly draw on spatial memory in order to plan efficient routes to goal locations, or (b) fall back on inefficient, but cognitively less-demanding, stimulus-response associations (i.e., habits). Using neuroimaging and behavioral measures, the investigators' protocol will test whether experimentally-induced stress leads individuals to bring fewer details about future locations to mind when route planning, and whether such restricted prospective thought ultimately biases participants towards relatively inflexible, habitual actions.
This project will modify a program that reduces pneumonia among nursing home residents with dementia, so that it is appropriate for assisted living residents with dementia. The program provides daily mouth care to reduce bacteria in the mouth that lead to aspiration pneumonia. The project will develop methods that can be taught to assisted living providers by community dental hygienists, and that are ready for evaluation in a pragmatic trial of AL residents with dementia and the staff who provide their care.
