Filter by:This study evaluate whether resistance training variables modulate the fatigability (power-duration relationship) and physical performance in adults and older adults
A study designed to compare evening versus morning levothyroxine intake in the elderly.
The current study will test whether age-related cognitive and mood changes in older adults and those with Parkinson disease will be affected by near infrared (NIR) stimulation. The overall hypothesis, drawn from previous literature, is that exposure to NIR stimulation will have positive effects on brain health and will result in better cognitive and mood performance.
An observational study of physical activity patterns in 150 older adults with cardiac implantable electronic devices (CIED)
20 healthy young subjects and 20 healthy older subjects will go through a medical examination. Subjects will be asked for their medical history especially on respiratory and cardiac diseases. All subjects will go through a spirometry test to evaluate their respiratory function. After their medical clearance each subjects will be asked to wear a CBRN respirator for 45 minutes. 15 minutes without filter, 15 minute with 0.8 cmH2O resistance, and 15 minutes with 1.2 cmH2O resistance. Throughout the test, Pco2 AND PO2 will be measured. The investigator will evaluate the effect of resistance (filter resistance) and the age of the subject on CO2 accumulation in the mask.
An accumulating body of research indicates that activities such as exercise, active cognitive and social engagement, good sleep hygiene, stress reduction and proper nutrition are associated with the maintenance of cognitive health. Emerging data also suggests that healthy lifestyle behaviors may promote brain plasticity. Despite nationwide efforts to raise public awareness about brain health, there remains a gap concerning how to best promote behavioral change and help at-risk middle-aged and older adults adopt effective, evidence-based brain health behaviors into their everyday lives to maximize cognitive health. The objective of this study is to evaluate the efficacy of a 7-week group brain fitness intervention (B-Fit) for increasing preventative brain health behaviors and enhancing cognitive health in participants at-risk for cognitive impairment. We will also examine mechanisms of action of the B-Fit intervention through tracking of behavioral responses in the real-world environment using wearable sensors.
Cognition encompasses memory, attention, language and other brain capacities that are necessary for good quality of life and independence. Age-related cognitive decline starts at the third decade of life and in some cases can start to impact daily functioning in the late forties. Dementia is the most devastating consequence associated with age-related cognitive decline. Recent studies indicate that improving cognition by means of intensive computerized brain training can mitigate some aspects of agerelated cognitive decline, and may even have a role in preventing or delaying dementia onset. Critically, the capacity of a given individual to improve their cognitive performance after training is fundamentally related to engagement with the exercises. Currently, little is known about how to apply intensive computerized cognitive training effectively in the health system, ensuring engagement and best progress. This project aims to tackle this challenge by developing, applying and testing personalized approaches to implement cognitive training in daily life of older adults that were recently evaluated at Memory Clinics and their care partners. The community readiness approach will be implemented using semi-structured interviews, conducted with subjects that may be interested in cognitive training, key informant, and key stakeholders. Using this information, the investigators will design an individualized training program and follow up its application in a feasibility trial. Twenty participants, recently evaluated at different Memory Clinics in Ireland, will be recruited, interviewed and invited to engage, over the ensuing 2 to 3 months, in computerized cognitive training. Subjects will be assessed after completion of the intervention for training adherence and individual gains on the computerized exercises. In order to gain insight about regional specificities of the approach the investigators will perform a parallel project using the same methodology in Brazil. This project is expected to inform the future implementation of cognitive training in public health policies for older adults.
The identification of a high atropine load of treatment received during hospitalization as a predictor of postoperative confusion could have various benefits: - Pharmacoepidemiological: identify factors associated with postoperative confusion - Clinics: by favoring treatments with a low atropine load during anesthesia, the management of patients hospitalized in orthopedics. Similarly, stopping or re-evaluating treatments with a high atropine weight for scheduled surgery is an easy step to take. - Socio-economic: by reducing the costs related to the occurrence of a confusional syndrome (over-treatment, prolonged hospital stay, loss of autonomy, institutionalization of patients...). In total, the present study would improve the daily management of hospitalized patients and the practices of clinicians, by offering a decision-making aid.
The investigators aim to use the new PET radioligand, 18F-MK-6240, to detect tau pathology in cognitive healthy and mild cognitive impairment (MCI) elders. The investigators will then examine the interactions between differential tau burden and performance on cognitive tasks, functional magnetic resonance imaging (fMRI) neural activation patterns, and other cognitive and behavioral measures. By investigating these relationships, the investigators hope to understand the cognitive and behavioral outcomes of tau deposition found in specific brain regions in cognitively normal/mildly cognitively impaired adults. Furthermore, the study aims to examine how the presence of tau may contribute to the risk of subsequent cognitive decline, neurodegeneration, and dementia.
As the french population is ageing, the question of medical care in elderly cancer patients is fundamental. A third of all cancer patients are 70 years or older. This population has specific challenges: autonomy maintenance, treatments efficacy with limited side effects. As a result of a call to projects, the Geriatric Oncology unit of the French Alps (UCOGAlp) has been selected by the National Institute of Cancer (INCa). It includes 15 centres in the Alpine area. This unit has been evaluated patients since 2011, giving them a full geriatric evaluation and trying to establish adapted cares. In order to evaluate the impact of those evaluation on patients' health, the investigators have developped a geriatric follow-up after 1 month (D30) and 4 months (D120). The investigators want to develop a common data base to these centres, in order to evaluate the care practices that were developped, and demonstrate the benefit for the patient on the dependence level and the overall survival.
