Introduction: Hand strength is a good indicator of physical fitness and frailty among the elderly. However, there are no published hand strength references for Malaysians aged > 65 years. This study aimed to establish normative data for hand grip strength (HGS) and key pinch strength (KPS) for Malaysians aged ≥ 60 years, and explore the relationship between hand strength and physical ability.Methods: Healthy participants aged ≥ 60 years with no neurological conditions were recruited from rural and urban locations in Malaysia. HGS and KPS were measured using hand grip and key pinch dynamometers. Basic demographic data, anthropometric measures, modified Barthel Index scores and results of the Functional Reach Test (FRT), Timed Up and Go (TUG) test and Jebsen-Taylor Hand Function Test (JTHFT) were recorded.Results: 362 subjects aged 60-93 years were recruited. The men were significantly stronger than the women in both HGS and KPS (p < 0.001). The hand strength of the study cohort was lower than that of elderly Western populations. Significant correlations were observed between hand strength, and residential area (p < 0.001), FRT (r = 0.236, p = 0.028), TUG (r = -0.227, p = 0.009) and JTHFT (r = -0.927, p < 0.001).Conclusion: This study established reference ranges for the HGS and KPS of rural and urban elderly Malaysian subpopulations. These will aid the use of hand strength as a screening tool for frailty among elderly persons in Malaysia. Future studies are required to determine the modifiable factors for poor hand strength.

Introduction: Inadequate oral care has been implicated in the development of aspiration pneumonia in frail geriatric patients and is a major cause of mortality, due to the colonisation of microbes in vulnerable patients. This type of pneumonia has been associated with an increase in respiratory pathogens in the oral cavity. The aim of this study was to evaluate the effects of chlorhexidine compared to routine oral care in edentulous geriatric inpatients.Methods: A double-blind, parallel-group randomised controlled trial was carried out. The intervention group received oral care with chlorhexidine 0.2%, while the control group received routine oral care with thymol. Nurses provided oral care with assigned solutions of 20 mL once daily over seven days. Oral cavity assessment using the Brief Oral Health Status Examination form was performed before each oral care procedure. Data on medication received and the subsequent development of aspiration pneumonia was recorded. An oral swab was performed on Day 7 to obtain specimens to test for colonisation.Results: The final sample consisted of 35 (control) and 43 (intervention) patients. Chlorhexidine was effective in reducing oral colonisation compared to routine oral care with thymol (p < 0.001). The risk of oral bacterial colonisation was nearly three times higher in the thymol group compared to the chlorhexidine group.Conclusion: The use of chlorhexidine 0.2% significantly reduced oral colonisation and is recommended as an easier and more cost-effective alternative for oral hygiene.

Introduction: WHO's Integrated Care for Older People (ICOPE) proposes we measure the functional construct of intrinsic capacity (IC) to monitor and identify individuals with age-associated vulnerabilities. Assessments of IC may be useful to address the evolving, non-HV care needs of ageing people with HIV (PWH). However, to date, its utility within the context of HIV has not been assessed., Methods: Participants included 200 PWH attending out-patient care (2021-2023) in Universiti Malaya Medical Centre, Malaysia and 101 community controls aged 35 years and above. The ICOPE framework was adapted to derive aggregate IC scores (ranging 0-6) encompassing the five domains of cognition, sensory (hearing and vision), mobility, mood and vitality. Multivariable analyses were used to explore the association of IC scores in PWH with multiple health outcomes including frailty, difficulties performing instrumental activities of daily living (IADL) and inflammatory markers. Area under the receiver operator characteristic (AUC-ROC) was calculated to predict frailty and IADL deficits in the current cohort and an independent cohort of 275 PWH from Hong Kong (HK)., Results: Median (interquartile range, IQR) age among PWH and controls were 50 (42-56) and 50 (39-59) years, respectively. There were more males among PWH (83% vs. 56%, p<0.001). All PWH received antiretroviral therapy (ART) for a median duration of 11 (8-14) years. Aggregate IC scores were lower in PWH but not significantly different compared to controls, (5.4 vs. 5.6, p = 0.093) and PWH performed significantly worse than controls only in the cognitive domain. Aggregate IC scores in PWH was independently associated with frailty (OR 0.17 95% CI 0.07-0.42, p<0.001), IADL deficits (OR 0.25 95% CI 0.14-0.46, p<0.001) and all other patient-reported outcomes assessed. Aggregate IC scores correlated with IL-6 but not sCD14 and sCD163 levels. IC scores performed well in identifying PWH with frailty (AUC-ROC ≥ 0.80) in the HK and Malaysian cohorts but more modestly (AUC-ROC ≥ 0.64) for IADL deficits., Conclusions: IC is a good composite measure to monitor non-HIV, age-associated physical and social vulnerabilities in PWH on ART and should complement disease-based monitoring in routine HIV care. Assessments of IC should be validated in larger, longitudinal cohorts of PWH from diverse settings., (© 2024 The Author(s).

Objective: Both changes in body composition and increased fall risk occur with increasing age. While weight management may be considered a component of falls prevention, the long-term consequences of changes in weight, however, remain uncertain. This prospective study aimed to evaluate the relationship between weight and body composition changes over 5 years with fall occurrence., Design: Prospective cohort study., Setting: Community-dwelling older adults interviewed at baseline (2013-2016) and follow-up (2020-2022) as a part of the Malaysian Elders Longitudinal Research study were included., Participants: Participants who attended face-to-face follow-up visits., Primary and Secondary Outcome Measures: Fall occurrence over 12 months preceding the follow-up visit was determined. Anthropometric, bioimpedance analysis and physical performance measurements were obtained at both time points. Participants were categorised into three groups according to changes in weight and body composition using≥5% increase or decrease in weight to determine loss or gain., Results: Of the 225 participants, aged 71.8±6.8 years, 128 (56.9%) were women. Weight gain was associated with increased fall risk at follow-up compared with stable weight (adjusted rate ratio, aRR (95% confidence interval, CI)=2.86 (1.02-8.02)) following adjustments for age and body mass index (BMI), but this relationship was attenuated by low baseline percentage lean body mass (%LBM) in women. The association was strenghtened after adjusting for age, BMI, and low muscle strength (aRR (95% CI)=2.89 (1.01-8.28)). Weight change did not influence falls risk in men. No difference was observed with changes in percentage body fat and %LBM over time with fall occurrence for both genders., Conclusion: Lower baseline lean body mass influenced the relationship between weight gain and falls longitudinally. Interventions addressing low lean body mass should be considered in the prevention of weight-gain-related falls in older women., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objective: Antiretroviral therapy has decreased the prevalence of retinal opportunistic infections in people living with HIV (PLWH). However, abnormalities in visual function are evident and may be associated with an early onset of aging in PLWH. In this study, we examined the Retinal Nerve Fibre Layer (RNFL) thickness and visual function in PLWH and HIV non-infected controls in Malaysia., Design: Cross-sectional study., Methods: Two hundred and two (202) PLWH without retinal opportunistic infection and 182 age-matched, HIV seronegative individuals were enrolled. PLWH were recruited from the Infectious Disease clinic at the University Malaya Medical Centre. Controls were recruited among the hospital staff and community volunteers. RNFL thickness was measured with spectral domain optical coherence tomography (SDOCT). Visual functions include visual acuity using LogMAR chart and contrast sensitivity using Pelli- Robson Chart., Results: All PLWH (mean age 46.1 years ± 9.9 years) in the study were on ART and 61.2% had a CD4+ T-cell count more than 500 cell/μl. The mean visual acuity was similar between the two groups (LogMAR 0.05 vs. 0.07, p = 0.115). Contrast sensitivity was lower in PLWH compared to HIV seronegative individuals (1.90 vs 1.93, p = 0.032). RNFL thickness was significantly thinner in the temporal quadrant for PLWH compared to controls (68.89 μm vs 74.08 μm, p = 0.001)., Conclusion: Changes in RNFL thickness and contrast sensitivity were seen in PLWH despite their relatively young age and well controlled HIV disease. The changes reflect structural and functional deficits, and could have long-term implications on their health trajectory., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Neelamegam, Nawi, Bashah, Hwei, Zulhaimi, Kamarulzaman, Kamaruzzaman, Ramli and Rajasuriar.)

This paper presents a state-of-the-art survey of smartphone (SP)-based solutions for fall detection and prevention. Falls are considered as major health hazards for both the elderly and people with neurodegenerative diseases. To mitigate the adverse consequences of falling, a great deal of research has been conducted, mainly focused on two different approaches, namely, fall detection and fall prevention. Required hardware for both fall detection and prevention are also available in SPs. Consequently, researchers' interest in finding SP-based solutions has increased dramatically over recent years. To the best of our knowledge, there has been no published review on SP-based fall detection and prevention. Thus in this paper, we present the taxonomy for SP-based fall detection and prevention solutions and systematic comparisons of existing studies. We have also identified three challenges and three open issues for future research, after reviewing the existing articles. Our time series analysis demonstrates a trend towards the integration of external sensing units with SPs for improvement in usability of the systems.
