Filter by:- Although aging process appears to be generally characterized, investigators have been paid much attention to the specific target molecules, which leads to discover the clinical markers of the senescence. The present study is to investigate the clinical and biological profile of cognitive decline and functional cardiac senescence in healthy middle aged and elderly Korean volunteers. - This study was conducted as a cross-sectional, single-center, comparative clinical study. - Each volunteer was given informed consent for checking cognition and cardiac function. Blood and urine samples were collected to analyze genome, proteome, and metabolome to assess cognition and cardiac function of its muscle enzymes.
In the present study, the effects of 5 days of lower limb immobilization with or without twice-daily protein supplementation on muscle mass and muscle fiber characteristics will be determined. A young group will be included to compare the changes in muscle mass and muscle fiber characteristics between young and old men.
The goal of this study is to understand the effects of muscle strengthening and stretching exercise intervention on isometric muscle strength, joint flexibility and running biomechanical patterns in older recreational runners. To do so, the subjects will be assessed before and after they engage in a 8-week exercise intervention program.
This study follows the results of the COMPALICLAMP study (NCT00951392) where the investigators showed a differential expression of sirtuins protein isoforms, Sirt6, in muscle depending on the quality of aging. The investigators seek to confirm this difference in expression level of circulating leukocytes on a larger sample.
The purpose of the study is to study the potential anti-inflammatory- and metabolic effects of polyphenols and dietary fibres in a product based on a mixture of several Swedish berries and vegetables that is known to have high amounts of polyphenols and other anit-oxidants. In addition the purpose is to investigate the effects on cognitive functions of the berry product.
The purpose of this study was to identify the effects and the efficiency of an adapted physical activity program as regards the physical condition of older Brazilian women.
It has well known that diets rich in fruits, vegetables and cocoa products are associated with positive health benefits and these positive effects have been shown to be due to compounds they contain called flavanols. Flavanols have been shown to exert their positive effects by indirectly increasing nitric oxide (NO) bioavailability. NO is a potent vasodilator that is believed to play a role in increasing blood flow to active muscle during exercise. This regulatory process is impaired with healthy aging. The underlying premise to this study is that if NO bioavailability can be increased following flavanol ingestion, will there be a restoration of blood flow during exercise in older individuals? Accordingly, the first part of this research project will compare the acute vascular effects of flavanol ingestion between a young and old group. The investigators have hypothesized that both groups will show an improvement in blood flow to active muscle during exercise, though the magnitude of the change will be greater in the older group. The second part of this project will look at the effects of 4 weeks of daily flavanol ingestion in the old group. The investigators hypothesize that subjects will demonstrate an improvement in blood flow to active muscle during exercise after the 4 week intervention and that the magnitude of the change will be greater than the acute effects. Findings from this proposal will provide evidence for the efficacy of flavanols to be used (as a simple and safe lifestyle intervention) to reverse or combat impaired blood flow regulation in older individuals.
Millions of diverse Veterans live with severe and chronic illness for which they will face complex, ongoing decisions. Although the VHA has been at the forefront of patient-centered chronic care, interventions to prepare Veterans for complex decision-making over the course of chronic illness are lacking. This proposal addresses this gap by testing the efficacy of a novel preparation guide designed to prepare Veterans to communicate with their surrogates and to work with clinicians to make complex, ongoing decisions. The multi-media guide teaches communication and preparation skill behaviors (e.g., how to choose a surrogate and ask clinicians questions) in a culturally appropriate, easy-to-use format (targeted to a 5th grade reading level). This study aims to provide an impetus for changing the paradigm of advance care planning policies within the VA by moving beyond documentation of end-of-life wishes to the activation of Veterans to participate in ongoing communication of their values and goals - a process that is essential to fully realize patient-centered care.
The "IMPACT Plus" Integrated Complex Care Clinic will create a team model of simultaneous interprofessional consultation and planning that brings together patients with complex or multiple chronic diseases, significant others/caregivers, the primary care team, community care providers and, uniquely, secondary consultation in real time at the primary care site. The purpose of this study is to evaluate whether the IMPACT clinic will reduce admission to hospital and visits to the emergency department (ED) in comparison to a control (usual care) group during a one year period of observation. Chart audits will be conducted on a monthly basis to calculate patients' complexity scores and data on all health services provided during the intervention phase, and compared between the intervention and control group. Additionally, surveys and semi-structured interviews aimed to measure patient, caregiver, and healthcare professional satisfaction of the IMPACT+ prior to and after initial assessment will be collected.
The purpose of this study is to test if an 8-week mindfulness meditation training (vs a wait-list control condition) program reduces neurobehavioral reactivity and improves affect regulation in a sample of older adults, as measured by functional magnetic resonance imaging. Additionally, we will examine if mindfulness meditation training reduces loneliness and markers of chronic inflammation.
