Healthy Ageing

The MIRACLE study aims to investigate age-related mitochondrial dysfunction, mitochondrial RNA (mtRNA) release, inflammation, and cellular senescence in adult participants across three age groups. Skin-derived fibroblasts and peripheral blood mononuclear cells (PBMCs) will be isolated from skin biopsy and blood samples to characterize age-related cellular and molecular changes and to test experimental therapeutic strategies identified in preclinical studies. Serum, plasma, and whole-blood RNA will be used for protocol-defined analyses of circulating inflammatory mediators and systemic transcriptional signatures related to inflammation, type I interferon activation, mitochondrial stress response, immune aging, and senescence-associated pathways.

Examining the effects of PeptiStrong and protein on muscle function in older adults

The goal of this intervention study is to screen and identify frailty and decline in intrinsic capacity (physical and mental capacities) in community-dwelling older adults in Singapore, and to evaluate whether early identification and targeted interventions can improve health outcomes and support healthy ageing. The main questions it aims to answer are: * Can combined frailty and intrinsic capacity screening with targeted interventions prevent or reduce functional decline in older adults, as measured by changes in life space mobility? * Will at least 80% of screened older adults adhere to recommended care pathways and interventions? * Can this screening and intervention programme demonstrate sustainability through continued community participation and recruitment of new partner organizations beyond the initial implementation phase? The investigators will compare an intervention group (receiving immediate assessment and clinical referrals based on identified needs) to a wait-list control group (receiving the same interventions 12 months later) to see if early intervention leads to better health outcomes and quality of life. Participants will: * Attend 4 study visits over 2 years (at 6-monthly intervals in the first year, with final assessment at end of year 2), each lasting up to 2 hours. * Undergo comprehensive screening assessments including mobility, cognition, mental health, hearing, vision, and nutritional status. * Receive 2 follow-up phone calls at 3-month and 9-month intervals to monitor progress. * If in the intervention group: receive personalized referrals for further care (which may include comprehensive geriatric assessment, primary care reviews, rehabilitation, or dietitian consultations) and guidance on using a mobile health monitoring application. * If in the wait-list control group: receive the same interventions after their 3rd study visit (12 months later).

This study investigates whether taking the amino acid L-serine, either alone or in combination with targeted strength training, can have a positive effect on mental performance, brain function, and physical fitness in older people. Healthy, independent women and men aged 65 to 85 are eligible to participate. Participants will be randomly assigned to one of three groups: placebo, L-serine, or L-serine combined with strength training. Cognitive tests, physical performance tests, and blood and brain tests will be conducted over a period of 48 weeks. The aim is to gain a better understanding of how nutrition and exercise can contribute to healthy aging.

The goal of this study \[type of study: clinical trial\] is to was planned to investigate the effect of motor imagery training given to geriatric individuals with action observation on their balance performance and to compare these two methods. The main questions it aims to answer are: 1. Is virtual reality-based balance training given together with action observation and motor imagery for six weeks in geriatric individuals more effective in improving static balance than virtual reality-based balance training given alone? 2. Is virtual reality-based balance training given together with action observation and motor imagery for six weeks in geriatric individuals more effective in improving dynamic balance than virtual reality-based balance training given alone? 3. Is virtual reality-based balance training given together with motor imagery for six weeks in geriatric individuals more effective in increasing balance confidence than virtual reality-based balance training given alone? 46 geriatric individuals will be randomized into 2 groups. Along with action observation, motor imagery training and virtual reality-based balance training will be given to the study group. On the other hand, only virtual reality-based balance training will be given to the control group. All assessments will be repeated before and after the trainings. The trainings will be applied 2 days a week for 6 weeks. Each training session; 25 minutes for the control group and 45 minutes for the study group.

The IMPACTFrail program is an intrinsic capacity (IC) identification and management program for mildly frail older adults. Specifically, it delivers the three-tier approach recommended in the National Frailty Strategy Policy Report. The program's core functions include the segmentation of older persons using the Clinical Frailty Scale (CFS) score followed by secondary IC screening for CFS 4 to 5 (Tier 1), follow-up clinical assessment to confirm IC losses (Tier 2) and needs-directed management and tracking of their health (Tier 3). The investigator aims to conduct a multi-site feasibility study on a small group of older adult study participants (n=30 per polyclinic). The feasibility study has a few components. First, a qualitative study will assess its feasibility (implementation, appropriateness, acceptability, practicality, adaptability) as perceived by older adults, healthcare providers, and healthcare administrators. Second, the investigator aims to collect process indicators to track its implementation progress. Third, program costs will be estimated. Fourth, the investigator will develop a logic model and theory of change, and cluster-specific detailed written program descriptions. Lastly, the investigator aims to triangulate the findings and assess the feasibility for larger-scale implementation. This study is guided by implementation science frameworks and guidelines for conducting feasibility studies.
