Filter by:Age with Health is a longitudinal cohort study aimed to examine trajectories of health, disability and wellbeing and their determinants for Spanish ageing population. Two waves have carried out so far. Wave 1 (2011-2012) and Wave 2 (2014-2015). Wave 3 will be conducted 2018, including also a new cohort of participants (Called 2018 Cohort). The study will provide reliable measures of population ageing and adult health in Spain - and will provide the basis for cross-country comparisons with longitudinal studies conducted in other countries.
The risk of developing cardiovascular diseases increases with aging largely due to age-related declines in the function of arteries (arterial dysfunction), which are influenced by common lifestyle factors such as consumption of a "Western" diet and lack of sufficient physical activity; thus, it is important to study how these factors interact to affect artery function. This study will determine whether changes to the gut microbiome (the collection of bacteria and other "microbes" living in the intestinal tract) with aging, Western diet consumption and aerobic exercise influence arterial function, and the biological pathways (mechanisms) involved. Specifically, the investigators will perform a randomized, single-blind, controlled feeding crossover study design (comparing Western diet to non-Western diet consumption) in young and older, exercising and non-exercising healthy adults to determine the time course effects (temporal association) of diet on the gut microbiome and arterial function. Overall, this research has potential to establish the gut microbiome as a possible target for treating/preventing age-related arterial dysfunction and reducing the risk of age-associated cardiovascular diseases.
Background: The transition to long-term care facility can be a stressful and emotional event for the elderly. The evidences showed that the prevalence of depression and the cognition impairment were higher in the institutionalized elderly than the community dwelling elderly. It could affect the quality of life of the elderly and increase risk of mortality. Purpose: The aim of the study is to evaluate the effect of outdoor activities and sunlight exposure on depression, cognitive function, and quality of life among institutionalized elderly. Method: The design is a randomized control trial. Participants will be randomly allocated to experimental or control groups by block randomization. In the experimental group, participants will be encouraged to reduce time spent on bed and bedroom. Nurses, nurse aids or family will take participants outdoors and exposure their face, hands or arm to sunlight for 15-30 minutes a day, five days a week for three months (if the UV index is over 8 according to the forecast of Center Weather Bureau, the participants will be asked to stay inside). In the control group, the participants will receive routine care. The control group will neither be encouraged to stay outdoors nor limit the chance to exposure to sunlight. Expected outcome: The expected benefit of the research is to improve the depression, cognitive function, and quality of life of the institutionalized elderly.
Background: When people have a stroke, they often have difficulty moving their arms and hands. Transcranial magnetic stimulation (TMS) can improve how well people with and without stroke can move their arms and hands. But the effects of TMS are minor, and it doesn t work for everyone. Researchers want to study how to time brain stimulation so that the effects are more consistent. Objective: To understand how the brain responds to transcranial magnetic stimulation so that treatments for people with stroke can be improved. Eligibility: Adults ages 18 and older who had a stroke at least 6 months ago Healthy volunteers ages 50 and older Design: Participants will have up to 5 visits. At visit 1, participants will be screened with medical history and physical exam. Participants with stroke will also have TMS and surface electromyography (sEMG). For TMS, a brief electrical current will pass through a wire coil on the scalp. Participants may hear a click and feel a pull. Muscles may twitch. Participants may be asked to do simple movements during TMS. For sEMG, small electrodes will be attached to the skin and muscle activity will be recorded. At visit 2, participants will have magnetic resonance imaging (MRI). They will lie on a table that slides into a metal cylinder in a strong magnetic field. They will get earplugs for the loud noise. At visit 3, participants will have TMS, sEMG, and electroencephalography (EEG). For EEG, small electrodes on the scalp will record brainwaves. Participants will sit still, watch a movie, or do TMS. Participants may be asked to have 2 extra visits to redo procedures.
A pragmatic randomized trial to evaluate the impact of an integrated patient experience and outcome measurement system supported by citizens, caregivers and community through eHealth technology. The primary research question is: What is the effectiveness of the WECCC approach on quality of life in people aged 65 and older or who self-identify as disabled compared to people not receiving the Health TAPESTRY program?
The goal of this randomized controlled trial is to investigate the effects of a dance intervention on cardiovascular risk factors and functional capacity of older women, comparing dancing to a walking exercise intervention and to an active control condition (stretching). The participants will include women between 60 and 80 years old, with body mass index inferior to 35 Kg /m2. The main outcome of this study is the peak oxygen consumption (VO2peak). The secondary outcomes are cardiovascular risk associated factors (C-reactive protein, TNF-alpha, lipid profile, etc) and functional performance (muscle strength and power, balance, gate ability, etc). The experimental design will include 3 parts: 1) Pre-intervention assessments: medical evaluation, fasting blood exams, maximum exercise test, assessments of body composition, balance, gate ability, muscular strength and power. 2) Period of interventions: patients will be randomized to one of the three following groups: dance, walking or stretching. The duration of the interventions will be 8 weeks, including 3 sessions per week for dance and walking, and once a week for the stretching group. Each session will last 60 min. 3) Post-intervention assessments: the same protocols of testing as pre-intervention.
There is evidence that computerized cognitive training can improve cognition in healthy older adults and in people at risk of developing dementia, although an effective model to implement the training in the daily life of people and to ensure engagement is missing. This project studies the adherence, engagement and progress on computerized cognitive training exercises that were offered by the Association of Retirees from the Telecommunications (ASASTEL) to its associates. One hundred subjects in three different cities (Rio de Janeiro, Belo Horizonte and Brasilia) received licenses to perform the exercises on line and were followed by a team of psychologists. We will evaluate adherence, engagement and progress on the computerized cognitive training exercises of those subjects.
This study aimed to pilot test a non-pharmacological (behavioral) treatment program targeting improved cognition through improving 24-h sleep-wake cycle in people with mild cognitive impairment (MCI) or mild Alzheimer's disease. A treatment program incorporating bright light therapy and a modified cognitive behavioral therapy for insomnia will be developed to address 24-hour patterns of sleep. We will then pilot test its feasibility and explore its preliminary effects on improving sleep/napping and cognition in patients with MCI or mild Alzheimer's disease.
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.
While it is well established that physical inactivity is a modifiable risk factor for vascular disease and cognitive decline, the mechanism by which exercise exerts its protective effect on the cerebral circulation and cognition is unknown. This knowledge gap was recognized recently in the Centers for Disease Control & Prevention and the Alzheimer's Association document "National Public Health Road Map to Maintaining Cognitive Health". Our rationale for these studies is that the identification of physical exercise as a lifestyle factor able to improve cerebrovascular reserve and cognition would establish a strong scientific framework justifying design of a randomized clinical trial that could evaluate the role of physical activity in cerebrovascular health and function. This research is based on data we obtained from a cross-sectional study that showed significant relations between physical fitness, vascular regulation and cognition. Cerebrovascular reserve and cognition were better maintained in women who were physically active but reduced in women who were sedentary. Our central hypothesis is that regular aerobic exercise mitigates age-related decreases in cerebrovascular reserve, which in turn imparts benefits in cognition. Further, we believe that these effects will persist after the structured aerobic exercise program is terminated. Our 18 month study began with a 6-month baseline period, followed by a 6-month exercise intervention, and a 6-month follow-up period. In addition, there are 5-year and 10-year follow-up periods. Volunteers (men and women aged ≥ 55 years) from the community were recruited using a variety of recruitment methods including media and distribution lists. After the baseline (pre-training) measurements, participants underwent a six-month aerobic training program, following guidelines previously used by us and according to the new exercise guidelines for older adults established by American College of Sports Medicine and the American Heart Association. The study involves comprehensive assessments of physical fitness, cerebrovascular responses to carbon dioxide at rest and during sub-maximal exercise, and an extensive battery of cognitive function tests.
