Filter by:This is a 2-part study evaluating the effects of IV administration of NR on healthy adult populations. Study 1 involved all four arms with 37 people. The second study only included the active NR and NAD+ arms to further evaluate tolerability and comfort of the IV.
Purpose: Healthy aging is the process of optimizing opportunities for health, participation and safety in order to improve quality of life as people age. This study aimed to provide healthy aging for people with cognitive impairment through the use of the Nintendo Switch combined with Occupational Therapy sessions. Material and methods: a randomized clinical trial was conducted. The sample was randomized using a software program, OxMar, which allowed the separation of the sample into a control group (CG), which received their usual sessions of conventional occupational therapy, and an experimental group (EG), which received therapy with Nintendo Switch, plus their conventional occupational therapy sessions. An 8-week intervention was conducted with Nintendo Switch. Measures: Nine Hole Peg Test, Box and Block Test, Barthel Index, WHOQOL-BREF, CSQ-8.
The goal of this interventional study is to test the efficacy of combined mindfulness meditation training and cognitive training on brain function and cognition in healthy older adults. Participants will undergo cognitive and neuroimaging (MRI and fNIRS) assessments before and after an 8-week (~20 hours) training intervention. The intervention will consist of at-home mindfulness meditation followed by playing a cognitive game on a provided tablet. The findings will be compared to an existing data from older adults who trained on the cognitive game only (NCT03988829; Arms 1 and 2).
This project aims to address the impact of frailty on older adults, particularly its connection to cognitive impairments such as dementia. By identifying frailty in its early stages, interventions can be designed to slow down the progression of cognitive decline. To achieve this, the project plans to develop a reliable at-home monitoring system that can accurately track frailty in older adults with mild cognitive impairment or dementia. By utilizing cutting-edge technologies such as high-precision indoor positioning and home-installed sensors, referred to as zero-effort technologies (ZETs), the system will collect continuous sensor data, which will be analyzed to identify indicators of frailty.
The primary goal of this project is to investigate whether online supervised team-based exercise training is superior for increasing functional strength in elders compared to prescribed self-administered exercise training. Secondarily, the project aims to investigate whether adherence to online supervised team-based exercise training is greater compared to prescribed self-administered training, and if online supervised team-based exercise training can increase quality of life. Finally, this project will generate more knowledge on elderly individuals' approaches and responses to physical exercise through online services. The participants will undergo a 12-week intervention where they will be performing prescribed physical exercise for 5 hours bi-weekly and complete a 3-day dietary registration three times during the study. Participants will be randomized (2:1 ratio) to two groups and will: i) undergo supervised training in groups on an online live meeting platform by trained personnel, or ii) receive prescribed exercises through an online exercise platform but their training will be self-administered and unsupervised.
A randomized, double-blind, placebo controlled, cross-over trial to investigate the effect of the Investigational Product "DailyColors™" (DC) on age-related pathways in adults. The aim of this study is to measure the effects of acute treatment with DC on key pathways relevant to healthy ageing using blood biomarkers. Based on power calculations a sample size of 20, is sufficient to detect an effect size of 0.46 at a power > 90%. To account for dropout the investigators will include 26 subjects in total.
The central hypothesis is that the addition of lean pork to a healthy plant-only diet will enhance nutrient adequacy to attenuate markers of cognitive decline, promote muscular fitness, and maintain immuno-metabolic functions for improved healthspan. A well-designed, randomized, controlled, crossover, feeding study with clinical and molecular mechanistic endpoints is proposed to provide the most definitive level of evidence logistically possible in humans and to establish the role of lean pork in healthspan promotion. Utilizing an all-food-provided (dine-in and take-out) design over 18 weeks (rolling recruitment, 8+8, 2w washout), a comprehensive assessment of metabolomics, system biology, physical, and physiological markers that indicate the risk of age-related comorbidities-critical micronutrient deficiency, frailty, metabolic dysfunctions, and cognitive decline, is proposed in upper Midwesterners 65 years and older. A plant-forward pork-added diet will be compared with an isocaloric plant-only control for over 250 outcome measures using mixed-effects modeling adjusting for covariates in R. n=15/diet/arm i.e., a total starting sample size of n=30 is proposed for 90% power.
The specific aims of the research study are: 1. Compare single-task gait parameters between individuals with hearing loss (HL) and age and education matched controls with normal hearing [normal vs moderate-profound hearing loss (N=23 for each group)]. For that we will compare the primary outcome measure, gait speed, between the groups while participants are walking at a comfortable speed for 1 minute. 2. Compare cognitive function between individuals with HL and age and education matched controls. For that we will compare the Neurocognitive Index, derived from a cognitive assessment between groups. 3. Compare the effect of a cognitive task while walking on gait parameters between people with HL and age education matched controls with normal hearing. For that we will compare the primary outcome measure, gait speed, between groups while participants are walking at a comfortable speed and counting backwards [serial subtraction of 3] for 1 minute. 4. Explore whether cognitive performance (i.e., the Neurocognitive Index) is correlated with Dual task cost (DTC), a deterioration of gait speed while walking and performing concurrent cognitive task [serial subtraction of 3]. The formula to calculate this is the following: DTC = 100 X [(DT - single task)/ single task].
The investigator has shown that improved cardiorespiratory fitness following an aerobic exercise program elicits cognitive benefit in elderly subjects and memory improvement in Alzheimer's disease (AD). The physiological mechanism may be related to exercise-mediated change in circulating factors that permeate the brain. The response to each individual bout of exercise (i.e. the acute exercise response) may differ between subjects and be key to driving brain benefit. In young populations, the acute response to exercise can last hours and affect brain glucose metabolism. However, the field knows little about this acute exercise response in AD. Most exercise intervention trials designed to prevent and slow AD, including our own (AG033673; AG034614; AG043962; AG049749; AG053952), assess biomarkers at two fasting time points: pre- and post-intervention. The acute exercise response in the brain and periphery likely varies between subjects and diagnoses and provide key information regarding mechanisms of benefit. Our primary goals are to characterize the acute exercise response to exercise in the brain (glucose metabolism) and periphery (biomarker response) in aging and AD. The investigator will identify relationships between exercise-related factors (i.e. heart rate, biomarkers) and change in brain metabolism and cognition. Understanding these mechanistic relationships will provide specific targets that can be used in future trials to develop individualized exercise prescriptions and maximize benefit. Accumulating evidence suggests that the exercise-related metabolite lactate is an understudied effector of brain health. Lactate is an essential fuel for neuronal function. It is supplied to neurons through glucose metabolism in nearby glia and from peripheral blood, since the brain is permeable to lactate. A drop in cerebral glucose metabolism is a marker of AD. Thus, supplying neurons directly with lactate for oxidation may supplement energy requirements in AD, as has been suggested with ketones. Importantly, circulating lactate levels rise during exercise. Repeated increases in systemic lactate (acute exercise response) may transiently spare glucose by providing an alternative fuel. With routine exercise, acute responses may elicit adaptations that facilitate the use of lactate beyond that which occurs during acute exercise and contribute to brain benefits observed during chronic exercise interventions. In younger populations, higher exercise intensity evokes a greater lactate response compared to lower intensities and elicits cognitive benefit. The investigator will achieve these goals through the following aim: Aim 1. Examine differences in lactate metabolism between diagnosis groups and the effect of lactate on cognitive performance. Increased blood lactate can reflect increased production or decreased uptake. This has never been compared in ND and AD. The investigator will use a "lactate clamp" procedure, where lactate is infused to concentrations that match those found during exercise, to characterize lactate turnover. The investigator will characterize cognitive performance following lactate infusion, independent of exercise factors. The investigators hypothesize that ND subjects (n=12) will use lactate more efficiently (greater uptake) than AD individuals (n=12). The investigator further hypothesize that cognitive performance will acutely improve after lactate infusion in ND and AD subjects. The overall goal is to characterize lactate metabolism, and its relationships with cognition. The KU ADC is a recognized leader in the study of exercise and metabolism in aged and AD populations, and puts the investigator in a strong position to successfully achieve these aims.
Objectives: The primary objective of the proposed project is to develop and evaluate a Community Dance Program (CDP) for community-dwelling older adults, which is aimed at promoting physical strength, balance, cognition, mental and psycho-social well-being of the older adults. A distinctive feature of our project is that a team of researchers across disciplines and community partners will collaborate to develop the program and bring benefits to the older adults living in the community.
