Filter by:Older patients with end- stage kidney disease (ESKD) are at very high risk for functional impairment. Kidney transplantation (KT) has the potential to ameliorate the detrimental effects of ESKD on physical activity and functional status. However, KT alone may not meet the full extent of this potential, particularly for older or more impaired adults. In fact, activity declines immediately post-KT and fails to return to expected levels even 5 years post-KT. Older patients waitlisted for KT (most of whom are on dialysis) are therefore reliant on their pre-KT levels of exercise, which are also predictive of post-KT mortality. "Prehabilitation" has been used in other surgical populations to minimize functional loss, and a structured exercise program may be beneficial in the pre- KT setting. However, few waitlisted patients are able to participate in typical exercise interventions due to barriers such as severe fatigue. Older patients have additional barriers such as further mobility impairment and requiring substantial caregiver support. Therefore for older living donor kidney transplant candidates, it is necessary to address issues such as specifics of coaching, timing, and importantly, incorporate caregiver participation. The overall objective of this proposal is to adapt a previously developed 8- week, home- based, structured exercise program among older (≥50 years) dialysis patients awaiting living donor KT, with a focus on caregiver involvement. The investigators will trial the exercise program as compared to usual care. The investigators will then pilot the refined intervention in a total of 72 patient-caregiver dyads, 48 of whom will undergo the proposed intervention (24 with caregiver participation, 24 without). The primary outcomes for the pilot will be change in physical performance and activity from baseline to after the intervention, along with measurements of exploratory quality of life outcomes. In addition, the investigators will measure these same outcomes at 3- months post KT to evaluate for a durable effect of the intervention. An additional post-transplantation outcome of interest will be number of days hospitalized within 3 months of transplantation.
Studies have determined that compared to cognitively intact older adults (CIOA), older adults with mild cognitive impairment (OAwMCI) exhibit more pronounced balance and gait impairments which lead to an increased risk of falls and mobility decline. Such impairments are evident during dual-tasking (i.e., simultaneous performance of cognitive and motor task) and OAwMCI have demonstrated an increased cognitive-motor interference (deteriorated performance of either or both cognitive/motor task). Furthermore, our preliminary laboratory findings indicate that compared to CIOA, OAwMCI in response to large-magnitude treadmill perturbations exhibits poor reactive responses (first line of defense against balance loss) and are unable to modulate their responses as the magnitude of perturbation increases. Despite that conventional exercise methods offer beneficial effects; they comprise of self-initiated task-specific exercises and may not focus on training reactive responses. Additionally, due to the presence of subtle balance and gait deficits, clinical measures used may not be sensitive enough to determine the risk of fall post-training. Furthermore, these training methods incorporate multiple sessions due to which adherence to exercise training is difficult with only a fraction of the older adults benefiting from it. Therefore, it is essential to incorporate a task-specific strategy that promotes factors associated with falling like balance control, muscular responses, coordination of limbs, and cognition through which OAwMCI may acquire maximum benefits to prevent a balance loss. One feasible method, which harnesses technology that can be used to deliver balance disturbances either while standing or walking in a consistent and controlled manner, is via a custom-based motorized treadmill. The scientific rigor from preliminary studies has reported a successful reduction of falls through a single session exposing CIOA to multiple treadmill-induced perturbations during gait and has shown significant improvement in reactive responses. For that reason, this stage 1 pilot study will examine the feasibility, applicability, and tolerability of a combined cognitive, and perturbation training on biomechanical determinants associated with falls and promote physical activity: kinematic variables, muscular responses, and cognitive function.
Background: Immunosenescence is an aging-dependent phenomenon underlying age dependent deterioration in the function of the immune system, characterized by a decline in B and T cells with a relative increase in natural killer (NK) cells. Aging also promotes chronic inflammation accompanied by increased levels of pro-inflammatory cytokines. Both immunosenescence and inflammation contribute to frailty, which is a geriatric syndrome characterized by age-related deterioration in multiple physiological systems resulting in greater vulnerability to stressors and increased risk of poor outcomes including longer hospital stays, postoperative complications, poor responses to vaccination, functional decline, and death. Although pharmacological interventions could be developed to address immunosenescence, inflammation and frailty, a dietary intervention that does not cause weight or muscle loss may be a preferable option, particularly if it is periodic in nature and it only needs to be adopted for a few weeks per year. Hypothesis: We will test the hypothesis that a newly formulated and relatively high calorie fasting mimicking diet (FMD) to be administered to subjects age 65-80 once a month for 5 days for two to six cycles can partially reverse immunosenescence and inflammation, thus contributing to the reduction of frailty. Aims: This proposal is divided into 2 main tasks: Task 1: We will determine whether FMD cycles in mice: a) prevent frailty syndrome onset and symptoms B) delay or reverse age-related immunosenescence and inflammaging, C) improve the functionality of bone marrow cells, D) enhances the response to flu vaccination. Task 2: A )We will develop a special relatively high calorie FMD medical food for testing in humans, B) We will test the safety and efficacy of the FMD medical food in an aged and frail individuals (65-80 yr) for 2-5 day cycles preceding their annual influenza vaccination. Expected results: In mice, we expect that the FMD diet will reduce the clinical signs of frailty during aging, and in particular increase immune system influenza vaccine response by preventing immunesenescence. We expect that the FMD will reduce phosphorylation of mTOR and of its downstream targets, and induce autophagy and apoptosis in WBCs. These effects are anticipated to remove damaged cells and promote the activation of hematopoietic stem cells and the generation of new WBCs. We also expect that the transient increase in corticosteroids and removal of damage immune cells will be accompanied by a decrease in systemic inflammation. Increased performance on rotarod and other measures of frailty is also anticipated. In humans, we expect that the FMD will be well tolerated by the pre-frail elderly without major adverse events and that it will be possible to achieve high compliance to this diet. We also anticipate that elderly undergoing the FMD protocol followed by 30 days of a normal diet plus supplements will exhibit better functional status and better response to the flu vaccine as compared to patients from the control arm. An improvement in handgrip strength and in lean body mass, as detected by BIA, is also expected, at least in a fraction of the patients from the intervention arm. Impact: Frailty is a geriatric syndrome characterized by age-related deterioration in multiple physiological systems and homeostatic mechanisms, resulting in greater vulnerability to stressors and increased risk of poor outcomes including longer hospital stays, postoperative complications, poor responses to vaccination, functional decline, and death. Thus, the identification of a dietary strategy, potentially to be applied for only 10 days a year but able to rejuvenate the immune profile and function while reducing systemic inflammation could have a major impact on both healthspan and health-related expenses. Because older individuals are often taking multiple drugs, the dietary intervention being investigated here would also reduce the potential toxicity of an additional pharmacological intervention.
This study is to compare the sustained post-discharge nutritional support to reach individual energy and protein goals to usual care home nutrition in medical patients at nutritional risk.
Background. Decreased taste and smell contribute to loss of appetite (anorexia), and the resulting protein-energy malnutrition increases the frailty of the elderly. The risk of falls, disability, infections and depression often requires them to be institutionalized. Elderly, undernourished and toothless patients often complain about the monotony of a soft, mixed-texture diet. In a previous study, some participants highlighted the pleasure of crunching cookies that have a solid texture that can be eaten in any dental condition. However, the age-related decrease in hearing (presbyacusis) is frequent and progressive from the age of 60. The hypothesis of this work is that older patients may perceive a crunchy food crunching in their mouth, despite presbycusis. If the hypothesis is verified, this would make geriatric caregivers aware of the possibility of diversifying the texture of food, in order to stimulate the pleasure of eating and increase the dietary intake in this population of patients who are often undernourished, dysphagic, edentulous and hearing impaired. The originality of this study is to share the expertise of geriatricians and specialists in mastication/swallowing (dental surgeon, speech-language pathologist), hearing (ENT doctor, hearing care professional) and nutrition (dietician). Type of study. Type of study MR-004 "Research not involving the human person". Protocol. Compare the noise and pleasure of crunching between two hyperprotein nutritional supplements: a soft filled cookie (Nutra Cake™, Délical, France) and a crunchy cookie of the Breton type (Protibis™, Solidages, France). Blind study impossible: each subject will eat a cookie then the other in a random order and will be his own control. The tests will be performed without the possible hearing aids, but with or without the dentures according to the patient's preference. Indeed, some patients have dental prostheses that are no longer suitable for chewing, and that they wear only for aesthetics. Objective. Validate the evaluation criteria "Do you hear the biscuit crunch?" and "Is it a pleasure?" If so, encourage diversification with crunchy foods with a suitable texture, as well as dental and prosthetic rehabilitation of dependent elderly people.

This will be a dose escalation, open label, single-center study in adult with frailty syndrome. UMC119-06-05 is ex vivo cultured human umbilical cord tissue-derived mesenchymal stem cells product which is intended for treatment of frailty syndrome.
Randomized clinical trial of 310 older adults over 75 years old recruited from the Falls Units of Geriatric Departments in 4 three University Hospitals in Spain (Pamplona, San Sebastián, Albacete and Barcelona). Participants who met inclusion criteria will be randomized to the usual care group (Otago exercise program) or the Vivifrail-Cog Intervention (a combination of physical exercise Vivifrail program and cognitive training). The main objective of the present randomized clinical trial is to investigate the effect of the combined intervention (exercise and cognitive intervention) in frail older participants living in the community and at risk of falling. The main endpoint will be the rate of falling in the following year. Secondary endpoints include physical performance, muscle strength, cognitive performance, hospitalizations, institutionalization, depression and quality of life.
The purpose of this study is to evaluate the effects of a home-based exercise program administered through Meals on wheels (MOW) on gait speed and frailty status and to assess the association between novel serum biomarkers (70 kilodalton heat shock proteins (HSP70),Macrophage Inflammatory Proteins(MIP1b), soluble IL-6 receptor alpha-chain (sIL-6R)) and established but non-specific frailty biomarkers (Interleukin 6 (IL-6), C-reactive protein (CRP), Tumor necrosis factor (TNF-α)) in frail and prefrail homebound older adults before and after the exercise intervention.
Singapore's population is ageing, and more elderly people are undergoing elective major surgeries. Frail elderly experience greater functional decline and slower recovery in physical function after surgery compared to non-frail elderly. Preoperative prehabilitation aims to enhance both aerobic capacity and physical strength of elderly to attenuate the post-operative decline in physical function. Singapore General Hospital has a bespoke preoperative program - Prehabilitation for Elderly Frail Patients Undergoing Elective Surgeries (PREPARE), where patients receive physiotherapy education and instructions for home-based unsupervised exercise program (uSEP). A hospital-based supervised exercise program had also been established but the take-up rate was low (7.6%) due to barriers such as cost and accessibility. Perioperative supervised exercise training can effect greater gains in functional capacity and muscle strength compared to no supervision. For the elderly with limited transport options to the hospital, home-based supervised programmes may be more convenient compared to hospital-based supervised programmes, but the former is costlier too. Home-interventions may also empower patients with the skills and confidence to maintain their physical fitness at home, which increases their likelihood of exercising after surgery. The investigators propose a prospective single-center randomized controlled trial to evaluate the efficacy of preoperative prehabilitation with a home-based supervised exercise program (SEP) for frail elderly patients undergoing major abdominal surgery, compared to the mainstay of clinical practice, which is a home-based uSEP.
The Falls Predictor Clinical Investigation is a research study that aims to investigate the value of an update (Falls Prediction RAMware) to an implantable cardiac monitoring device (The Reveal LINQ™) in predicting unexplained falls. The Reveal LINQ™ is an implantable cardiac monitoring system manufactured by Medtronic that has the ability to monitor heart rate, rhythm and activity and is preprogrammed to detect abnormalities. An R&D team at Medtronic has been collaborating with the study PI Prof Rose Anne Kenny on this project they are responsible for developing a software update for the Reveal LINQ™ that would enable the device to collect additional sensor data such as accelerometer (step count) and Posture change. The additional investigational fields along with the standard cardiac fields that are monitored may be useful in predicting or identifying physiological changes before a fall. The study will involve up to 30 patients, recruited and consented from recurrent non-accidental fallers referred to the Falls and Syncope Unit at St James's Hospital, Dublin.
