Filter by:The Helsinki Businessmen Study (HBS) is a clinico-epidemiological longitudinal study started in 1964. It also included a 5-year randomized, controlled multifactorial primary prevention trial of cardiovascular diseases between 1974-1980. The cohort is being actively followed-up through national registers since the 1980, and since 2000 with regular questionnaire surveys. Latest in 2015. Also clinical and laboratory studies have been performed in random subcohorts. Follow-up is ongoing with new hypothesis-generating research questions.
The purpose of this research study is to evaluate the effects of combining physical exercise with a resveratrol supplementation on the physical function of older adults.
The emergency department (ED) is a common source of acute illness care for older adults. Many older adults who are discharged home from the ED return within 30 days due to numerous challenges faced during the ED-to-home transition. Unless programs to improve the ED-to-home transition are identified, the health and financial costs will only increase as the older adult population doubles by 2040. This study will apply Coleman's Care Transitions Intervention to the ED-to-home transition by adapting the program to account for the unique aspects of the ED setting. The research will evaluate the process, ED use, and cost outcomes of a community-based, paramedic-coordinated Care Transitions Intervention. Upon completion, this study will provide empiric evidence regarding this innovative approach to help the rapidly growing older adult population remain healthy and independent after an ED visit.
The purpose of this study is to verify the effects of a strength training program on functional capacity, muscle performance and microcirculation in the elderly.
In today's society, the search for keeping up with the appearance with no visible signs of aging has become common. Therefore, many therapies to try to mitigate these senility markers are present in specialized clinics. Such therapies seek grounding in the theories of how the skin and its appendages respond to the aging process, causing this way, they can be created ways to slow or minimize wrinkles and other consequences of this natural biological process. However, this process can be accelerated by exposure to ultraviolet light such as to toxic substances as well as tobacco, among others. The low-power laser and light emitted diode (LED) characterized by being non-ablative light source, which means phototherapy which does not cause physical damage to the epidermis, as the case of CO2 laser ablative and other methods. This study has the purpose of comparing the effects of combined application of low level laser with LED and LED action alone in facial rejuvenation. For this, the analysis of these effects will be conducted through digital photography, blinded assessment and customer satisfaction questionnaire.
The UNCODE Study seeks to better identify the neurological causes of muscle weakness associated with advancing age. The main study consists of 4 laboratory-based testing sessions that involve testing muscle strength and physical and cognitive function as well as a battery of tests to 1) quantify brain excitability (using non-invasive transcranial magnetic stimulation), 2) modulate brain excitability (using non-invasive transcranial direct current stimulation), 3) spinal motor nerve firing characteristics, and 4) brain structure and function characteristics based on magnetic resonance images of the brain. Additionally, three option sub-studies are also available for enrollment. The first is a genetics sub-study where a cheek swab will be used to examine associations between certain genes and the physiological and functional measures obtained from the main study. The other two sub-studies are interventions. The first sub-study is a progressive resistance exercise training study where study participants will undergo 12-weeks of exercise training (3x/wk) and at the completion of the exercise training the measures obtained in the main study will be re-assessed. The other sub-study is a mental imagery sub-study where subjects are randomly assigned to perform a mental imagery training program consisting of imaging strong muscle contractions and mobility tasks (5x/wk) or to serve as a control (i.e., to not modify lifestyle) for 6-weeks. At the completion of the respective intervention period the measures obtained in the main study will be re-assessed.
The purpose is to use MRI to investigate brain changes associated with playing a race car video game for 90 minutes in aging adults both with and without early signs of dementia.
Arterial stiffening and endothelial dysfunction are correlates of advancing age contributing to the decline in cardioprotection with age. Arterial stiffness and endothelial dysfunction are emerging risk factors for cardiovascular disease and predict future cardiac events. Vascular function has long been a target for lifestyle interventions with several studies showing improvements traditional exercise modes. However, the impact of yoga on vascular function remains elusive. This study will determine the effect of a 12-week Bikram yoga intervention on arterial stiffness and endothelial function in healthy, middle-aged adults. The overall aim of this study is to determine the efficacy of Bikram yoga in improving vascular endothelial function and arterial distensibility in middle-aged adults with risk factors for coronary artery disease and to determine whether the heated environment plays a role in mediating these alterations in vascular function. The investigators propose to conduct a 12-week Bikram yoga intervention study in sedentary individuals in order to test the following hypotheses: 1. Bikram yoga will elicit reductions in arterial stiffness and enhancements in endothelial function in sedentary, middle-aged adults. 2. The postulated effects of Bikram yoga will be greater when practiced in a heated environment.
In adulthood, limited mobility and pain are very common and often the first clear sign of functional decline. The loss of independent mobility is related to higher rates of functional disability and mortality; however, it is also susceptible to interventions through exercises. With aging, changes in peripheral and central nervous system also occur, which lead to degradation of the sensory receptors as well as a loss of muscle mass and coordination. However, both, structural and functional dysfunctions of the nervous system, can be mitigated by increasing physical activity. The aim of this study is therefore, to study the effects on pain and functional capacity of a therapeutic exercise training program in an adult people sample. The therapeutic exercise machines proposed in this trial have not been previously analyzed and provide insight into this field due to their design. The design of this new machines allows the adaptation to each concrete clinical situation by the adjustment of different parameters such as feedback, range of movement, time of repetition, intensity, speed and rhythm, which facilitate motor control training.
In recent years, evidence has shown that mitochondrial dysfunction plays an important role in the development of age-related muscle decline that may lead to frailty. During aging, there is a progressive reduction in the cell's capacity to eliminate its dysfunctional elements by autophagy, as evidenced by the accumulation of oxidative damage and mutations in mitochondria and by the decrease in autophagic flux. In fact, it has been demonstrated that dysfunctional mitochondria can be specifically targeted for elimination by autophagy, a process that has been termed mitophagy. A major challenge in the clinic today is in the lack of validated tools, including biomarkers, to assess the decline in mitochondrial health associated with an impairment in muscle function. In the present study, the investigators will employ a battery of established and exploratory tests (clinical, physiological and molecular) to assess in vivo mitochondrial function and more specifically, the levels of mitophagy and autophagy, in the muscle of healthy and pre-frail elderly. It is anticipated that the results of this study will facilitate the rapid translation of interventions targeting mitophagy and autophagy for the improvement of muscle function.
