Filter by:Basic science and observational human studies suggest that high conentrations of circulating Advanced Glycation End-products (AGEs) may promote cognitive decline in older adults. The purpose of this pilot study is to test the methodology and feasibility of a dietary intervention to lower AGEs in elderly diabetics in order to lay the foundations for a future fully powered randomized clinical trial (RCT).To this end, the present study is focused on recruitment strategies, adherence to an innovative intervention in older adults and study methods. An exploratory aim will be the effect of the intervention on cognition and cerebral blood flow in order to obtain necessary data to estimate effect-size for a future fully-powered RCT.
Heterogeneous modalities of aging lead to describe three categories of elderly patients: 1-healthy without frailty, 2- healthy with frailty, 3- patients with chronic disease(s) and frailty. Frail people have a high risk of losing functional independence and as a consequence they require more help for day to day life. It is known in elderly that physical activities, nutrition, social environment are important to maintain functional independence. For patients with disabilities, less is known about the occurence of dependance with aging. That is of growing importance because life expectancy of disabled patients has increased a lot during last decades, and because caregivers, often parents, also become elderly and frail. So the investigators will require tools to anticipate prevention and supportive needs for this specific population. The goal of this study is to evaluate if the participants (disabled patients over 40 years old) of a well-defined region in the south-east of France (400000 inhabitants), and to assess their needs, using the Functional Autonomy Measurement System (SMAF) developed for assessment of the elderly, by Rejean Hebert & Nicole Dubuc's team in Sherbrooke University (Quebec/Canada).
Motivations: Socio‐economic and education determinants have a big impact on health outcomes, in terms of worse health status in populations living in more disadvantaged conditions. Social capital, self‐management and health literacy are some of the intermediate determinants, with the potential to mitigate health inequalities through interventions driven by local health agents. These three determinants are intensely interlinked and have, separately, impacts on self‐perceived health. Social capital is defined in this project as an umbrella concept, which includes quantitative aspects of social resources (structural social capital: social networks and contacts, social and civic participation) as well as qualitative or subjective aspects (cognitive social capital: perceived social support, feeling of belonging and trust) and covers relations between subjects at a micro or individual level (family and friends) as well as at a macro or community level. Health literacy is understood as cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand and use information in ways which promote and maintain good health. Both are key aspects for self‐management behaviours. The target of our research project are older people living in urban socioeconomically disadvantaged areas, since ageing is in itself an inequality axis and urban environments concentrate the highest health disparities. Objectives: With the aim to reduce health inequality, an intervention has been designed to promote self‐management, health literacy and social capital among older people who perceived their health as fair or poor and are living in urban socioeconomically disadvantaged areas with the aim of improving their self‐perceived health. Secondarily, the efficacy of the intervention will be analysed in terms of increasing self‐management, health literacy and social capital (social support and social participation), quality of life, mental health and healthy lifestyles. In third place, behavioural health patterns will be identified in relation to health literacy, social capital, gender, socioeconomic and educational level, and they will be linked to the intervention efficacy levels.
The purpose of this study is to examine the effects of modifiable lifestyle factors including exercise and healthy living on brain health. The investigators will compare 2 types of interventions, moderate aerobic walking vs. healthy living education, over 6 months to evaluate changes in brain health, cognition, and physical function in older adults with cognitive concerns.
The purpose of this study is to compare the safety and efficacy of Neuramis® Volume Lidocaine, which is a biomaterial prosthesis and graft, with Juvederm® Voluma® with Lidocaine, for the patients who need correction due to a moderate-to-severe volume loss in the mid-facial region by inducing temporary volume restoration in mid-facial region. After the pivotal study, extension study will be conducted to confirm long-term safety and efficacy.
This study plans to learn more about how age and weight impact appetite and food intake. Specifically, this study is being done to see whether age and obesity impact appetite and the brain's response to food. In this study the investigators will be evaluating how participants brains respond to food images as well as your food-related behaviors and hormones. The investigators will be comparing older individuals aged 65 to 85 years who are normal weight compared to those who are obese. The Investigators will then compare older aged individuals to younger adults aged 21 to 45 years.
The overall aim of this study is to evaluate the effects, meaning and significance of a person-centred and thriving promoting model for residential aged care in Australia, Norway and Sweden. More specifically, the following research questions will be explored: 1. Can a person-centred and thriving promoting care model increase residents' thriving, and have a positive impact on residents' perception of the caring environment? 2. Can a person-centred and thriving promoting care model increase relatives' satisfaction with care, and have a positive impact on their experience of visiting their relative, and perception of the caring environment? 3. Can a person-centred and thriving promoting care model increase staff's job satisfaction, decrease stress of conscience, and have a positive impact on their perception of the caring environment and person-centred care? 4. What meaning and significance do relatives and staff ascribe to the intervention? The study is designed as a multi-centre, controlled group before-after design with participating sites in Victoria (Australia), Oslo (Norway) and Västerbotten (Sweden). Two residential aged care facilities at each site will be allocated to either intervention or control, in total three intervention and three control facilities divided over the three sites. Care staff at the intervention facilities will participate in a 12-month education on how to integrate aspects of person-centredness, thriving and a caring environment into daily care practice. Participating staff will work together with their colleagues and members from the research group to create a reflective and creative learning environment that builds on and develops the staff members' clinical experience and skills, and combines it with theoretical and research-based knowledge. At the control facilities, care staff will participate in a 2-hour lecture on the theoretical and philosophical foundations of person-centredness, thriving and a caring environment, and then continue with practice without further involvement from the research team. Evaluation data will be collected by study specific questionnaires before the education starts, immediately after the education and at a 6-month follow-up. In addition, focus group interviews and individual interviews will be conducted with a selection of staff members and relatives at the intervention facilities to explore meaning and significance of the intervention.
With aging, the elderly decreased ability to control postural balance will be accompanied by increased risk of falling (Berg et al, 1992;. Tinetti et al, 1988). According to previous studies, it showed that the elderly over 65 years fall each year probability was 30 %, and it increased with age (Skelton, & Todd, 2004). In view of this, age-related posture control has become important issues of modern preventive medicine and family care.
The primary aim of this NIA sponsored ancillary study of phase 2 CALERIE is to measure whether metabolic adaptation lasts up to 2 years in response to a 25% calorie restriction in normal-weight and slightly overweight individuals. Energy metabolism (24-hour sedentary and sleeping) will be measured in a respiratory chamber. Other measures include the activities of the sympathetic nervous and thyroid axes, oxidative stress in lipids, protein and DNA, organ size by MRI and echocardiography, and posture allocation (time spent engaging in different activities and the energy expended during these activities), and activity temperament (the innate predilection for movement). This set of studies will allow assessment of whether the previously observed metabolic adaptation in response to 25% caloric restriction is long lasting (up to two years), associated with reduced thyroid and sympathetic activities and reduced oxidative damage. The studies of organ sizes (liver, spleen, kidney, heart, adipose and muscle) by MRI and echo (heart) is essential to determine whether the metabolic adaptation is related to decreased organ sizes or improved organ energy metabolism efficiency. The above described measures will be performed at baseline and after 1 and 2 years of a 25% caloric restriction in 50 non-obese humans and in 25 sex-, BMI- and age- matched subjects who will not engage in caloric restriction.
The purpose of this study was to examine the effects of resistance training on sarcopenic obesity in older women.
