A Health-social Partnership Programme for Improving Health Self-management of Community-dwelling Older Adults

Health-social partnership has been governed by regulations in many developed countries for some years. For instance, the government of United Kingdom has implemented a policy specifically designed to facilitate the discharge of older adults by collaborating health and social care workers in hospitals. The United States also formulated a policy to support the development of collaborative and multi-agency care services in community setting for helping those who are vulnerable and underserved including ethnic minorities, homeless people, and those without health insurance. While these services were shown to reduce the delays in hospital discharge and improve access to services, they were found to be health-dominated and the involvement of service users in strategic design and planning was lacking. As a result, the actual process in practice was reported to be poor and a true model of health and social care partnership was not attained. Currently in Hong Kong, health-social partnership has not yet been driven and guided by policy. It is still unknown for researchers and practitioners as how to effectively build a seamless working partnership among two different disciplines and sustain in the community to support the independent living of older adults.

The Effect of Training on Brain Activity During Postural Tasks in Older Adults

Older people show deficits in dynamic weight-shifting, as the investigators found that more time is needed to perform weight-shifts and the movements became less fluent and accurate in older versus younger adults. Deficits with weight-shifting in the mediolateral (left-right) direction have been linked to balance and falls in ageing. Balance control can be improved with training. Virtual reality (VR) based training programs for improving balance are gaining ground, as it can provide both fun and challenging balance tasks, enhancing motivation. The investigators demonstrated earlier that older adults show an overloaded neural activation pattern compared to young adults when performing the same VR-based mediolateral weight-shifting task (wasp game). What is yet unclear, is whether improved balance capacity can be gained with training and whether such an intervention impacts the underlying neural mechanisms. Using a combination of behavioral assessments and functional Near-Infrared Spectrocopy (fNIRS), the primary aim of this study is to investigate the effects of a VR-based weight-shift training and its underlying neural imprint in older adults. Next to the wasp game, a mediolateral tracking task will be used to standardize weight-shifting speed to allow a comparison of fNIRS data during stable weight-shifting performance. Furthermore, as a previous study done by the investigators also showed that adding an extra cognitive task in a so-called dual-task (DT) negatively affects weight-shifting performance, a secondary aim will be to test whether weight-shift training will enhance performance during such DT conditions. The results of this study may contribute to the future design of technology-based rehabilitation programs.

Resistance Training on Elderly Resilience

Background: There is on one hand sufficient evidence showing strong association between resilience and self-rated successful aging. On the other hand, strength training could contribute the cultivation of resilience among older adults. Therefore, the current study aims to examine the effectiveness of resistance training on resilience among Chinese older adults in Hong Kong. Methods: This study will apply a three-group, double blinded (outcome assessors and data analysts), randomized controlled trial (RCT) to examine the effectiveness of the interventions on resilience, functional fitness, and health related quality of life immediately after a 16-week intervention, as well as the residual effects 12 weeks after completion of the interventions. Discussion: It is expected that resistance training is promising or even superior to aerobic training in the improvement of resilience. Given the limited evidence on the literature, it is urgently needed to explore the effects of resistance training on the improvement of resilience in older adults. Findings of the current study can contribute to the development of effective resistant training programs for the promotion of resilience among older adults.

A Novel Computer-Based Functional Skills Assessment and Training Program

People with cognitive impairments such as Mild Cognitive Impairment (MCI), often experience difficulty performing everyday routine activities. Further, normative age-related changes in cognition often lead to deficits on previously learned skills and impede new learning such as learning of new technology systems. This is of great concern, given population aging, the increasing number of older adults with cognitive impairments, and the continual deployment of new technologies in everyday contexts. The objectives of this SBIR Phase II study is to build on a previous Phase I SBIR project and refine and further evaluate a novel integrated computer-based functional skills assessment and training (CFSAT) program that provides training on everyday tasks critical to independent living (e.g., financial and medication management) with non-impaired older adults (NC) and adults with MCI.

The Impact of Watermelon Juice on Blood Pressure

L-citrulline is found naturally in watermelon. Recently interest has increased for this amino acid due to potential health benefits. Notably, L-citrulline has the potential to lead to dilation of blood vessels due to its involvement in the production of nitric oxide. The study will be an acute single blind, randomised controlled, crossover intervention study in healthy, young volunteers. Participants receive either the test watermelon drink or control drink (water). Blood samples and vascular measures (by a single-cuff based method) will be measured at baseline. Vascular measures will be repeated at 15-minute intervals between 0-2 hours and a second blood sample will be drawn at 1.5 hours to coincide with the estimated peak plasma L-citrulline. Citrulline, arginine and nitric oxide metabolites will be measured in the blood samples.

Cause-effect Relationships Between Brain Networks and Bimanual Coordination in Older Adults

In this study, high-definition dual-site transcranial alternating current stimulation (i.e., non-invasive brain stimulation) will be applied to boost the fronto-parietal network during a bimanual coordination task in healthy young and older adults. Previous studies indicated that this network is important in initial motor learning, possibly through its role in spatial working memory. Therefore, stimulation will be applied during both a pure spatial working memory test, and during a bimanual coordination task. It is also shown that healthy older adults do not engage spatial working memory brain regions during motor learning, which is related to worse motor learning. Therefore, the investigators will investigate whether this type of stimulation can improve bimanual motor learning in healthy older adults.

CUHK Brain Health Longitudinal Study

The goal of this study is to develop a large longitudinal cohort of individuals diagnosed with or at high risk for brain diseases (both neurological and psychiatric in nature), in order to identify risk factors that contribute to neurological and psychiatric diseases over time. The investigators seek to capture relevant information from medical records, electronically administered questionnaires and follow up phone-based interviews. The investigators expect to eventually have sufficient power from our dataset to examine risk factors for a variety of brain disorders, both individually and in aggregate. Our ultimate goal is to offer scientifically validated ways to preserve and promote brain health by working with our patients' needs and tracking their progress over time.

Implementation of the Integrated Care of Older People App and ICOPE Monitor in Primary Care (ICOPE)

Introduction: The World Health Organization has launched the INSPIRE-ICOPE-CARE program towards healthy aging. It includes "intrinsic capacity", defined as "the composite of all the physical and mental capacities of an individual", which has a positive value towards prevention, and is constructed by five domains: cognition, vitality/nutrition, sensory, psychology, and mobility. ICOPE App and ICOPE Monitor are applications for the self-assessment and monitoring of intrinsic capacity. Hypothesis: Intrinsic capacity self-assessed by the ICOPE Apps could be associated with the incidence of frailty and health outcomes. ICOPE Apps might support geriatric and primary care during the COVID-19 pandemic and beyond. Objectives: To assess the association between intrinsic capacity measured by the ICOPE Apps at baseline and the incidence of frailty in community-dwelling older adults during 1-year follow-up. Secondarily, to assess the association of intrinsic capacity and pre-frailty, falls, functional decline, institutionalization, and mortality (COVID-19-related/not related). Methods: Protocol for a cohort study of community-dwelling adults ?65-year-old, with no other exclusion criteria than the inability to use the Apps or communicate by telephone/video-call for any reason (cognitive or limited access to telephone/video-call). Intrinsic capacity measured by the ICOPE Apps and Rockwood's clinical frailty scale will be assessed at baseline, 4-, 8- and 12-month follow-up by telephone/video-call. Assuming a prevalence of frailty of 10.7%, and incidence of 13% (alpha-risk=0.05), 400 participants at 12-month end-point (relative precision=0.10) and 600 participants at baseline will be required. Associations among the decrease in intrinsic capacity, incidence of frailty, and occurrence of health adverse outcomes during 1-year follow-up are expected. ICOPE Apps might identify individuals at higher risk of frailty and health adverse consequences. The implementation of the ICOPE Apps into clinical practice might help to bring the practitioners closer to their patients, deliver efficient person-centered care-plans, and benefit the healthcare systems during the COVID-19 pandemic and beyond.

Longitudinal Analysis of Gait Variability to Predict Falls in Parkinson's Disease

The broad goal of this research project is to improve the prediction of falls in patients with Parkinson's disease (PD) through a comprehensive multidisciplinary approach that includes longitudinal measurements of walking, cognitive and functional performances. PD is a life-changing disorders affecting one million Americans, with more than 60,000 new cases reported every year. Within 3 years of diagnosis, more than 85% of people with clinically probable PD develop gait problems, which in turn lead to falls resulting in serious injury and reduced quality of life. There is a pressing need to identify fall risk factors before the occurrence of the first fall, and to better understand behavioral and cognitive changes leading to falls in PD patients.
