This proposal will evaluate two brain health measures, cerebrovascular perfusion and cerebrovascular reactivity (CVR), before and after a proven, interval-based, aerobic exercise intervention in older Veterans. The hypothesis is that the 12-week aerobic exercise intervention (Spin) will increase perfusion and improve CVR in brain regions susceptible to age-related decline. This information will inform the impact of exercise on cerebrovascular health which is known to be negatively impacted in aging and implicated in the development of neurogenerative disease. This information will also aid the investigators' continued efforts of clinical implementation of evidence-based exercise interventions in the local Atlanta VA and surround region.
The objective of the clinical trial is to evaluate the mediating influence of force control on the pegboard times of adults (50-89 years) who are stratified into groups of faster and slower pegboard times. The hypothesis is that practice of either a pegboard test or a force-control task will reduce pegboard times, but the decrease will be greater and less similar after the two practice interventions for the slower group of participants. The outcomes are expected to demonstrate that force control is a modifiable mediator of pegboard times for this cohort, but the effect will be stronger for the group with faster pegboard times.
The goal of the research proposed in the current application is to first define how much antibody aging renal transplant and dialysis recipients make after they are vaccinated with the pneumonia vaccine and how this compares to similar aged persons with good renal function and healthy young adults. The investigators will study differences in the kind of B cells and markers on the B cells that are known to be important in the response to the pneumonia vaccine in aging renal transplant and aging dialysis recipients compared to similarly aged and young healthy controls. Finally, the investigators will study how safe the pneumonia vaccine is in aging renal transplants. The answers to these questions will help in designing a better vaccine for older people with a renal transplant or on dialysis.
The objective of this study is to recruit a group of older adults and study a broad set of physical health, mental health, and social outcomes when participants exercise with an older adult, peer-led exercise program. The program to be evaluated is called Zoomers on the Go. It is a 12-week program which involves two 60-minute sessions per week and educates participants about falls, along with aerobic and resistance exercise, flexibility, and balance activities. The program is offered to older adults (age 50+) and it is delivered in their community by an older adult who is trained as a certified Zoomers group exercise leader. Participants will be recruited, then randomized so that half of them can participate in a Zoomers class in the spring (intervention group) while half will have to wait until the fall of 2019 (control group). Pre-testing for both groups will begin around March 2019. The intervention group will participate in the program for 12 weeks, then there will be post-testing following this 12-weeks for both groups. Outcomes will be compared for the intervention and control groups, to determine if there are changes in the data pre- to post-measurements that are evident solely for the intervention group.
In most Western countries the elderly population increases rapidly. In Denmark, the population of elderly aged 75 years or older may amount to nearly 15 % of the entire population in 2050 compared to 9 % today (2017). A large part of the elderly population is at high risk of hospitalization including more admissions and increased morbidity and mortality. The number of hospital beds is declining persistently, calling for shorter lengths of stay (LOS). Increasingly complex treatments now take place outside hospital. Presently, many Danish regional hospitals establish geriatric wards and other geriatric in-hospital and outpatient services to overcome these challenges. The aim of the present PhD-study is to investigate the effects of different models of transitional care among the frailest elderly patients.
The primary purpose of this protocol is to develop a reliable method to determine BAT mass in young and older adults by magnetic resonance imaging.
It will be an experimental study conducted with elderly of both sexes, these will be divided randomly into three groups and the intervention will happen twice a week, for 60 minutes, for 12 weeks. The aim of the study is to compare the effect of different volumes of Pilates exercise training on muscle strength, postural balance, flexibility, functional autonomy, depressive symptoms, quality of life and lung function in the elderly community. The investigators believe that Pilates exercises will have beneficial effects for the elderly, but the hypothesis is that the group that performs a greater volume of Pilates exercise training will have a greater improvement in the investigated outcomes than the group with the lowest volume.
Older adults often experience substantial deficits in walking ability, especially for walking tasks that are more complex such as obstacle crossing. This is due in part to changes in the brain that make performance of physical and cognitive tasks more difficult. Rehabilitation can help to improve walking ability, but effective rehabilitation is time consuming and expensive. New approaches are needed to improve the efficiency of rehabilitation so that gains in walking ability are widely attainable. A promising strategy is to focus on enhancing motor learning, which is defined as improved ability to perform a motor task due to practice or experience. The investigators will investigate the use of non-invasive brain stimulation to increase motor learning and retention of the newly learned walking skills. The investigators will also use neuroimaging to assess brain characteristics that explain how motor learning works. The knowledge gained from this study is expected to contribute to better understanding of mechanistic targets and intervention approaches to improve rehabilitation of walking.
Purpose Frailty and multi-morbidity have been associated with increased pressure on Emergency Departments (ED), higher hospital admissions and more risks for patients arising from the ED stay. The advantages of developing specific attention to frailty in ED have been highlighted. The benefits of these approaches are related to patients but also to organizations. The aim is to present how a Program of Care for Frailty (PCF) in an ED impacts on patient health and flows. Objective is to analyze the clinical impact of Comprehensive Geriatric Care (CGA) in the Emergency Department (ED) and on patient flows Setting: A tertiary, teaching, 550-bed urban hospital, with 80,000 adult patients/year ED attendances (43%≥65 years). Two periods are compared: First period (before CGA implantation) del 01/04/2016 - 15/04/2016 and second period (after) 01/04/2017 - 15/04/2017
There are many tests that evaluate fall and balance. As a clinical test, the Four Square Step Test (FSST)Test is reliable, valid, easy to score, quick to administer, requires little space, and needs no special equipment. It is unique in that it involves stepping over low objects (2.5cm) and movement in 4 directions. FSST was developed in 2002 to measure the rapid stepping that is often required when changing direction and avoiding obstacles while walking. The FSST requires a stopwatch and four single point sticks. Using the sticks resting flat on the floor to form a cross, the subject starts in one square and steps in one direction into each of the four squares and then reverses direction back to the start. The FSST is unique in that it challenges motor planning, sequencing and recall, whilst simultaneously providing clinicians with the opportunity to measure and observe a person's clearance of low obstacles at speed. The ability to clear the trail leg when stepping over an obstacle has been shown to be reduced in healthy populations. Dual task is simultaneous performance of two tasks that can be performed independently, measured separately and with different goals. Individuals have difficulties in performing two tasks together. When two tasks are performed at the same time, deterioration in performance of one or both is called dual task interference. This occurs when task requirements exceed the capacity. Age, walking speed, lower extremity muscle strength and cognitive status are factors that contribute to the dual task. In addition, prioritizing the motor or cognitive task in a dual task affects the dual task performance. Knowing these factors and improving some of them can help to create training programs designed to improve the dual task performance of individuals. There are several studies investigating factors contributing to dual task performance that focus on balance in the elderly. However, the studies including middle age group are limited. There are no studies evaluating the factors contributing to the single and dual task performance of FSST in the literature. In this study, it is aimed to explain the factors related to motor and cognitive functions to the single and dual task performance of FSST.
