Filter by:The population older than 80 years will significantly increase in the near future. Older patients' cognitive and physical status is known to deteriorate after surgery, leading to a high 30-day mortality due to post-operative comorbidities. Aging and related diseases share immune-related pathomechanisms. During aging, a chronic, low-grade sterile inflammation, called inflamaging, gradually develops. This likely results from low-grade innate immune activation and a functional, epigenomic and transcriptomic reprogramming of immune cells. Based on the hypothesis that surgical trauma leads to misplaced or altered self-molecules, which exacerbate inflammation and the postoperative risk for morbidity and mortality in elderly patients. There is increasing evidence that the individual's pre-operative immunobiography determines the susceptibility to peri-operative inflammation and post-operative outcome. Current exploratory pilot study will thus perform phenotyping of patients above 80 years undergoing major surgery. Participants will be evaluated for acute and long-term outcomes, including all-cause mortality, physical and cognitive function. To assess the individual's immunobiography, participants will be characterised by inflammation biomarkers combined with immunophenotyping, functional assays, and (epi-) genomic analyses before and after surgery. The cognitive impairment will be evaluated by measuring markers of neurodegeneration and neuropsychiatric testing and relate findings to volumetric imaging using high-resolution MRI to identify brain changes associated with cognitive decline.
Senior Companion Programs (SCP) facilitate partnerships between community volunteers and local homebound seniors. Seniors served by the SCP will be provided with a companion who will conduct weekly visits with them, help with meal preparation or deliveries, provide transportation, assist with simple housekeeping, and socialize with the client amongst other tasks. These services are directed towards helping the senior client continue living independently in their own home instead of moving into an assisted living or nursing home. The SCP model is being evaluated to determine the impact of the services on the client's overall well-being and independent living status.
The purpose of this study is to use an experimental inflammatory challenge to examine whether older adults with symptoms of anxiety experience loss of pleasure or loss of motivation when they are exposed to inflammation. Loss of pleasure or loss of motivation will be evaluated using self-report questionnaires, computer tasks, and during a brain scan.
The aim of this project is to estimate the effects of therapy with dance and movement and Tai Chi on irisin plasma levels, a myokine with proven neuroprotective effects, in the context of baseline levels of cognitive function and physical performance in seniors over 65 years of age. It is empirically verified that physical activity can have a positive effect on cognitive function even in individuals with mild cognitive impairment. There may be a number of reasons why this is the case. Recently, research investigating the relationship between the secretion of certain myokines and their neuroprotective effects has gained importance. One of these myokines is irisin, which has recently been shown to have beneficial effects on the CNS by upregulating the expression of Brain Derived Neurotrophic Factor (BDNF) in the hippocampus in an animal model. Increased irisin levels as a consequence of exercise have recently been partially demonstrated in humans. What type of physical activity is most effective in terms of its effect on cognitive function in humans is another important scientific challenge. The possibility of influencing endocrine secretion of bioactive substances with proven effects on synaptic plasticity, neurogenesis and neuroprotection through effective therapies may help to combat neurodegenerative diseases, the prevalence of which is increasing with the average age of the population. According to Alzheimer's Disease International, 50 million people worldwide were affected by some form of neurodegenerative disease in 2017. The number of people affected is still rising. It is predicted that this number will reach 75 million sufferers by 2030 (https://www.alz.co.uk/research/statistics). Alzheimer's disease and multiple sclerosis are the two most common manifestations of neurodegenerative diseases. The effect of therapy with dance and movement and the effect of Tai Chi on blood irisin levels in the context of cognitive function and physical performance levels, has not yet been conclusively demonstrated.
The multi-disciplinary and translational VOILA project presents a unique intersection between gut, immuno-metabolic, and musculoskeletal health. The main goals of the project are to develop biomarkers for healthy aging and prevent disease by maintaining quality of life in older adults. Within this umbrella project, the multimodal VOILA lifestyle intervention study will assess the impact of a twelve-week strength training and nutritional intervention in older adults with different degrees of mobility. The study will improve the current understanding of the complex relationship between gut and muscle health in different segments of mobility and obtain an insight into the heterogeneity of responsiveness between individuals.
Competitive sport increases risk for musculoskeletal injury (e.g., traumatic knee injury) and may position former athletes for early onset of chronic diseases, chronic pain, poor health-related quality of life, and disability. Quantifying function in former athletes with and without a prior injury and non-athlete controls is critical to understanding long-term health trajectories in athletes and informing potential interventional studies. One modifiable factor that may be associated with long-term health in athletes is physical activity patterns. The purpose of this study is to evaluate strength, function, physical activity, dietary patterns, and cardiometabolic health among current and former competitive athletes and in nonathlete controls to evaluate the impact of prior knee injury and sedentary behavior as two potential determinants of later poor health and reduced function.
Keep brushing your teeth, twice a day, during life for healthy teeth and body. Not brushing your teeth regularly and well, may have a devastating effect on your teeth and your general health. The teeth could develop root caries resulting in pain, fractured teeth, tooth loss and trouble eating. Further, brushing your teeth insufficiently leads to higher number of bacteria in the oral cavity and could in frail individuals lead to aspirations pneumonias. With age, some of us will depend on daily care activities from others and help with daily toothbrushing. However, care dependent older adults often lack basic dental care (tooth brushing with fluoride tooth paste twice a day). Dental care at home is a service proved by dental personnel. Visits at a dental clinic decrease with age and especially with a dementia diagnosis. Dental care at home can deliver regular dental check-ups and dental treatments to individuals who experience difficulties attending a dental clinic. The effect of teeth cleaning performed at home on root caries development, has not yet been explored in care dependent older adults. Therefore, the aim is to study if the combination of high fluoride toothpaste used daily with teeth cleaning/ a reminder to use the toothpaste every third month, could be a method for preventing root caries development in this patient group. The hypothesis is that domiciliary professional cleaning will improve the oral health, as measured by root caries development, gingival bleeding, plaque accumulation and oral mucosal status, compared with a control group that receives oral care as usual.
B cube is a new generation cohort to study the determinants and natural history of brain aging, using molecular epidemiology, in a representative sample (N=2000) of the general population from the age of 55 (the approximate age of onset of the first cognitive disorders and a target population particularly receptive to prevention messages). Special interest will be given to nutrition, a promising environmental exposure for prevention.
The researchers plain to build a large-scale, longitudinal, prospective cohort characterized by TCM dampness syndrome. With the biobank of this cohort the investigators want to find the causality between TCM dampness syndrome and clinical chronic diseases and a new way to treat clinical disease.
Vascular and skeletal muscle function decline with age and are associated with decreased nitric oxide (NO) bioavailability. Dietary nitrate supplementation in the form of beet root juice increases NO bioavailability and improves exercise tolerance in younger adults, yet its effects on fatigability in older adults are largely unknown. The proposed research will investigate the impact of increased NO bioavailability on vascular function, skeletal muscle bioenergetics, and fatigability in older (≥65 yrs) men and women.
