Filter by:Bone marrow samples will be collected from patients undergoing hip arthroplasty surgery. Blood and bone marrow samples will be used for metabolic profiling and analysis of relevant CHIP mutations. Combined single-cell transcriptomics and mutation-specific single-cell genotyping (biotin-PCR using mutation-targeted primers followed by sequencing) will subsequently be performed. The gene expression profile of wildtype and mutant hematopoietic stem cells will be compared, performing both broad gene set enrichment analysis and targeted analysis of metabolic pathways.
Aging is associated with progressive impairment of tissue and organ function, resulting in increased susceptibility to chronic disease, frailty and disability. Currently there are limited treatment options to alter this inevitable process. The proposed work has the potential to identify a new therapeutic intervention to decrease aging-related degenerative processes. Rapamycin or sirolimus is a macrocyclic immunosuppressive drug that inhibits the mammalian target of rapamycin (mTOR). The mammalian target of rapamycin (mTOR) pathway is part of phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR)-dependent pathway which is a fundamentally linked to cell metabolism, proliferation, differentiation, and survival. This pathway is altered in a variety of diseases, including cancers, immunosuppressed states, and fibroproliferative diseases. The mTOR kinase is considered one of the leading regulators of this pathway. Changes in mTOR signaling are closely associated with inflammation, cell growth and survival, leading to the development of chronic diseases. Recent evidence also suggests that mTOR inhibitors are promising modulators of the aging process by slowing the mechanisms of aging at the cellular level. There is a growing appreciation of the potential impact of sirolimus in slowing aging processes and in prolonging healthy lifespan. The proposed study addresses critical gaps in our understanding of the safety and efficacy of sirolimus in delaying aging processes and is based on findings in animal studies and incidental clinical observations. The investigators will overcome potential biases with a randomized control trial. The proposed intervention study is intended to improve our insight into clinical outcomes leading to prevention of chronic diseases such as skin cancer and mortality. Our overarching hypothesis is that sirolimus is one of the first pharmacological agents that will impact the aging process and chronic disease development. Specifically, the investigators aim to investigate whether sirolimus can reduce the occurrence or increase in biomarkers of aging processes.
With increasing longevity, a significant increase in the incidence of neurodegenerative diseases is expected. According to forecasts based on data from the World Health Organization and data from epidemiological studies, up to 106 million people will have Alzheimer's disease in 2050, it's 1 in 85 people living on the planet. If it will be possible to manage to delay the onset or slow the progression of the disease by a single year, it will mean 9.2 million fewer patients worldwide. This leaves considerable scope for options to modify the onset and prevalence of the disease through lifestyle changes such as eating habits and exercise. It is known that the human brain retains a certain natural plasticity even in old age, which is a great advantage that allows it to adapt to physiological stimuli, such as regular exercise. The pleiotropic beneficial effects of exercise therefore have considerable potential to be used in the prevention and slowing of the progression of cognitive and motor function decline as well as in the prevention / treatment of metabolic dysregulation. This fact is supported by many epidemiological and interventional studies with exercise, emphasizing the importance of the global trend to use exercise as a standardized method of prevention and treatment of many chronic diseases and cognitive deficits.
The proposed study seeks to evaluate effectiveness, implementation processes, and cost of MOTIVATE among older Veterans with chronic musculoskeletal (MSK) pain and comorbid depressive symptoms.
Every-day life means being part of a complex environment and performing complex tasks that usually involve a combination of motor and cognitive skills. However, the process of aging or the sequelae of neurological diseases such as Parkinson's disease (PD) compromises motor-cognitive interaction necessary for an independent lifestyle. While motor-cognitive performance has been identified as an important goal for sustained health across different clinical populations, little is known about underlying brain function leading to these difficulties and how to best target these motor-cognitive difficulties in the context of rehabilitation and exercise interventions. The challenge of improving treatments of motor-cognitive difficulties (such as dual-tasking and navigation) is daunting, and an important step is arriving at a method that accurately portrays these impairments in an ecological valid state. The investigators aim therefore to explore brain function during complex walking in healthy and PD by investigating the effects of age and neurological disease on motor-cognitive performance and its neural correlates during three conditions of complex walking (dual-task walking, navigation and a combination of both) using non-invasive measures of brain activity (functional near infrared spectrometry, fNIRS) and advanced gait analysis in real time in young, older healthy adults and people with PD.
Recent work in the investigators laboratory has examined the ability of a non-invasive 13CO2 breath-test to assess differences in amino acid oxidation rates and net balance in young healthy males following protein feeding and resistance exercise. The investigators aim to test the efficacy of this non-invasive 13CO2 breath-test to assess for differences in anabolic sensitivity between young and older adults following an acute period of habitual and reduced physical activity.
The investigators will assess feasibility and acceptability of the Tele-Tai Chi (TC) intervention; explore changes in clinically relevant outcome measures including: physical activity, self-efficacy, quality of life, cognitive function, balance, gait, and evaluate changes in TC proficiency. To achieve this, the investigators are running a single-arm study for older adults that involves a 12-week home-based Tai Chi intervention. Study participation includes four remote and/or in-person (at Spaulding Rehabilitation Hospital) visits to evaluate study participants (mobility tests and questionnaires).
To fill up the research gaps and build up a healthcare service model for geriatric trauma patients, this two-stage study aims to (a) develop geriatric trauma Artificial Intelligence (AI) prediction models by comparing the outcomes from clinical assessment and AI joint images; and (b) examine the long-term effects of an innovative health service program in geriatric trauma patients.
Residents living in long-term care (LTC) homes spend up to 75% of their day in sedentary, socially withdrawn situations which increases their risk for depression, dementia, decreased functional status and increased care costs. Physical activity is an accepted intervention to improve the physical health, cognition, and well-being of older adults. Moreover, systematic reviews have found that exergaming (i.e. physical activity gamified with technology) offers physical, cognitive, and social benefits by means of dual-task activities that engage both motor and cognitive abilities. The effect of exergaming for older adults in LTC is less clear, as this population has greater health needs related to physical health conditions, cognitive impairment, and functional dependence. Given the increased global demand for LTC, there is a need to develop and assess innovative exergaming technologies that can support the physical and cognitive health of LTC residents. MouvMat is an exergaming technology intervention with an interactive digital gaming surface designed for older adults (OA) in LTC settings. Participants can play familiar games, like Simon or Bingo, by stepping on or tapping the surface with an assistive pointing device. Games can be played individually or with multiple players. LED lights on the surface provide an adaptive digital display and embedded pressure sensors respond to players' input. The investigators collaboratively designed a preliminary prototype with OA aged 65 and older in a pilot project. The overall objective of this proposal is to conduct a pilot RCT of the Mouvmat to evaluate the feasibility, acceptability and efficacy of the exergaming technology to improve the primary outcome of mobility, and the secondary outcomes of cognitive function and social isolation compared to a usual care control group receiving standard recreational programming by recreational therapists.
