Filter by:The main goal of this study is to determine the metabolic availability of methionine in black beans, lysine in sorghum and lysine in milk using the indicator amino acid oxidation method both in older and in younger men.
The primary objective of this observational study is to verify, through a comprehensive geriatric assessment, the health status of a sample of elderly subjects.
In the field of sport/health, the prescription is generic and individualisation, which is still very rare, is generally linked only to physical performance. These limitations on the implementation of the sessions will result in limiting the effects of the training programme and increasing the risk of injury. It is therefore necessary to develop knowledge and tools to assist physicians and physical activity professionals in their decision making. The aim of the study is to improve the precision of the calculation of the training load in order to better individualise the management of the participants.
The main goal of this study is to determine the difference in amino acid digestibility of milk, sorghum and black beans between older (65-80 years) and younger (20-35 years) adults using the dual tracer method.
Ageing is accompanied by a high risk of developing physical or cognitive impairments, as well as a decrease in abilities to perform two tasks simultaneously, contributing to loss of autonomy. Interventions based on the performance of cognitive-motor dual tasks show positive effects on cognitive, physical and emotional development on dual-tasking capabilities. Exergames, interactive serious games combining physical activity and technology, are a certain type of cognitive-motor dual task training. These exergames appear to be cognitively effective, discussed on a physical level, not studied on dual task functions. It is likely that a dual task cognitive-motor with the support of a exercise leads to the same benefits as training without the need for special support. In addition, the exergames benefit from specific features such as a good immersion and a playful aspect that increase the participant's adhesion. Moreover, the level of security of this type of programme has been little studied. It is likely that cognitive-motor dual tasks training supported by an exercise programme leads to few undesirable events and good adherence. Many of the recommendations specific needs gaming state that it is important to develop systems that respond to the needs specific to the population concerned in order to be effective. Within the laboratory HAVAE has been developed a tool, the "virtual carpet": association between a video-projected scene and a monitoring system of position of the participants. This system makes it possible to use as a grid of play the cartography and iconography of the City of Limoges. The investigators suppose that this emphasis on local heritage will encourage the participants leaving their homes, thereby increasing their level of physical activity and their quality of life.
Background: The ability to retrieve specific memories is a cognitive and emotional protective factor. Among the most effective techniques to generate autobiographical memories is the use of audio-visual stimuli, particularly images. Developing and improving techniques that facilitate the generation of such memories could be highly effective in the prevention of depressive symptoms, especially in the elderly population. The aim of the present study is to examine how the level of personal relevance of pictures as autobiographical memory cues to induce positive emotions may affect an individual's emotion regulation. Methods: The participants, 120 older adults aged 65 and over and 120 young adults aged between 18 and 35, of both sexes and without depressive symptoms, will be induced to a negative mood state by means of viewing a film clip. Following the negative mood induction, the participants will be shown positive images according to experimental group to which they were randomly assigned (high personal relevance: personal autobiographical photographs; medium personal relevance: pictures of favourite locations associated with specific positive autobiographical memories; and low personal relevance: positive images from the International Affective Picture System). The investigators will analyse the differences in subjective (responses to questionnaires) and objectives measures (EEG signal, heart rate variability and electrodermal activity) between the groups before and after the induction of negative affect and following the recall of positive memories. Discussion: The use of images associated with specific positive autobiographical memories may be an effective input for inducing positive mood states, which has potentially important implications for their use as a cognitive behavioural technique to treat emotional disorders, such as depression, which are highly prevalent among older adults.
The investigators aim to undertake a 49-month longitudinal study in a cohort of 360 healthy individuals of 60 years and older, living in East Anglia to understand the role of gut microbes (the microbiome) in healthy ageing. The investigators also aim to identify changes in the structure and function of the gut microbe populations that are associated with deteriorating mental health and cognitive function. Using clinically validated cognitive assessments and tests, study participants will be stratified in to one of three risk groups for developing dementia:- Cohort 1 - low (n=120). Cohort 2 - medium (n=120). Cohort 3 - high (n=120). Participants will be recruited from three streams - Primary Care, The NHS Bowel Cancer Screening Programme (BCSP) and the Norfolk & Suffolk Foundation Trust (NSFT). Following initial Telephone Contact and the Pre-Study Visit, all participants will be required to attend the Quadram Institute Clinical Research Facility (QI CRF) every 6 months over 4 years. At each of these follow-up visits, the participant will provide a stool sample (collected at home) and at differing time points, provide a blood sample and undergo a series of physical measurements, cognitive tests/questionnaires and complete a health questionnaire. All participants will undergo Optical Coherence Tomography scans at the Beccles & District War Memorial Hospital. There will be 2 subgroups in this study. Subgroup 1 - at least 30 participants from each cohort (n= at least 90) will undergo colonic tissue biopsies as part of routine clinical care using the NHS BCSP. Subgroup 2 - 30 participants from Cohort 3 will undergo brain imaging at the Norfolk & Norwich University Hospital (NNUH) Imaging Department. The results of the study will provide new insights into the gut-brain axis and the relationship between age-associated changes in gut microbe populations and declining mental health. Such insights will be of enormous value in developing new microbe-based strategies to improve lifelong health and wellbeing that impact on dementia development.
The aim of this study is to determine whether dairy or plant based fats combined with fish oils can alter skeletal muscle mitochondrial, physical, and cognitive function.
The purpose of this study will be to examine the feasibility of a Physical Activity Intervention for Loneliness (PAIL) in community-dwelling older adults. The research is a feasibility study designed as a two-arm randomised controlled trial (RCT) with a wait-list control group (intervention will be offered at 12 weeks to control group).
The EMMY Project is an interdisciplinary and mixed methods comparative study on impact of welfare systems on mental wellbeing among the oldest old in Finland, Italy, Norway and Spain, including aspects such as equity, social inclusion, empowerment and participation. The project will delineate the concept of mental wellbeing at old age by qualitative methods, and will dissect the links between welfare systems and mental wellbeing by quantitative methods. It will support exchange of good policies between EU Member States by performing case studies of existing welfare policies and systems in the four participating countries, and it will develop a new research-based tool for assessing the mental wellbeing impact of welfare policies in old people. The overarching aim of this interdisciplinary, comparative research project is to improve our knowledge and understanding of how different welfare models and related policies, as well as health and social care service approaches, can benefit from adaptation in order to target mental wellbeing in the oldest-old. The project will support development of social welfare models in order to incorporate a change of focus from mental disorders to mental wellbeing among old people. This is important, not only because of the ageing of the European population, but also because of increasing pressures on public finances, within and beyond Europe.
