    Parkinson's disease (PD) is the second most common neurodegenerative disease. The etiology of PD remains an enigma with no available disease modifying treatment or cure. Pharmacological compensation is the only quality of life improving treatments available. Endogenous dopaminergic neuroregeneration has recently been considered a plausible therapeutic strategy for PD. However, researchers have to first decipher the complexity of adult endogenous neuroregeneration. This raises the need of animal models to understand the underlying molecular basis. Mammalian models with highly conserved genetic homology might aid researchers to identify specific molecular mechanisms. However, the scarcity of adult neuroregeneration potential in mammals obfuscates such investigations. Nowadays, non-mammalian models are gaining popularity due to their explicit ability to neuroregenerate naturally without the need of external enhancements, yet these non-mammals have a much diverse gene homology that critical molecular signals might not be conserved across species. The present review highlights the advantages and disadvantages of both mammalian and non-mammalian animal models that can be essentially used to study the potential of endogenous DpN regeneration against PD.

    INTRODUCTION: During the coronavirus disease 2019 (COVID-19) pandemic, the use of virtual consultations has accelerated to ensure continued access to healthcare despite lockdowns and physical distancing measures. We aimed to determine the knowledge (awareness) of, attitude (acceptability) to, and practice (exposure) [KAP] of virtual consultations (VC), the demographic factors associated with poor KAP, and the correlation between the three KAP domains.

    METHODS: A cross-sectional study, using a convenience sampling technique, was conducted from 13 September, 2021 to 28 November, 2021. We designed a 45-item VC KAP questionnaire. This was distributed to outpatient users attending cardiovascular, dermatology, geriatrics, haematology, endocrine, respiratory, gastroenterology, rheumatology, or neurology clinics at the University Malaya Medical Centre. It was completed during face-to-face, online, or telephone interviews. The data were analysed using SPSS version 24.0. Binary logistic regression was used to determine the demographic factors associated with KAP. Correlation between KAP domains was determined using Spearman's rho (r). A p-value of <0.05 was considered statistically significant.

    RESULTS: A total of 366 questionnaires were completed. Knowledge (awareness), attitude (acceptability), and practice (exposure) were considered good in 69.7%, 80.9%, and 24.6% of participants, respectively. There were no significant relationships between age, gender, ethnicity, and duration of hospital attendance (years) with knowledge (awareness), attitude (acceptability), and practice (exposure). A moderate positive correlation was seen between knowledge (awareness) and attitude (acceptability) (Attitude total [Atotal]) (r = 0.48, p<0.001), with no significant correlation between knowledge (awareness) and practice (exposure) (r = 0.04, p = 0.45), and attitude (acceptability) (Atotal) and practice (r = 0.01, p = 0.82).

    CONCLUSION: Overall, outpatient clinic users had good knowledge (awareness) of and were receptive towards VC but had poor practice (exposure). More opportunities for VC use in healthcare can increase exposure and subsequent utilisation. Interventions to increase the effectiveness of VC use should be explored in future studies.

    BACKGROUND: Knee osteoarthritis (OA) is a common cause of physical disability among older adults. While established risk factors for knee OA include age and increased body weight, few studies have examined psychosocial risk factors or progression of knee OA.

    METHODS: The Promoting Independence in our Seniors with Arthritis study recruited participants aged 65 years and over from orthopedic outpatients and community engagement events. Participants were invited to annual visits during which knee OA symptoms were assessed with the Knee Injury and Osteoarthritis Outcome Score (KOOS), social network using the 6-item Lubben Social Network Scale and anxiety and depression using the Hospital Anxiety and Depression scale. Knee OA worsening was defined by a 5% reduction in mean KOOS scores at the last visit compared to the first visit.

    RESULTS: Data were available from 148 participants, mean age 66.2±6.5 years and 74.1% female, of whom 28 (18.9%) experienced OA worsening over a median follow-up period of 29 months. Univariate analyses revealed that age, sex, height, grip strength, and social network were associated with OA worsening. Social network remained statistically significantly associated with OA worsening after adjustment for age and sex difference (odds ratio=0.924; 95% confidence interval, 0.857-0.997). The relationship between social network and OA worsening were attenuated by both depression and handgrip strength at baseline.

    CONCLUSION: Psychological status and muscle strength may be modifiable risk factors for social network which may in turn prevent knee OA worsening and should be targeted in future intervention studies.

    BACKGROUND: Independent and safe medication self-management is essential for successful aging. Nevertheless, how older adults with cognitive frailty (CF) self-manage medications at their own homes remain elusive.

    OBJECTIVE: This study aimed at assessing the medication self-management capability of home-dwelling older adults with CF and exploring the ways, perceived challenges and barriers in medication self-management.

    METHODS: A convergent mixed-method study design was used. The medication management capability of 16 CF individuals aged ≥ 60 years on ≥ 1 long-term prescription drugs were assessed using the Drug Regimen Unassisted Grading Scale (DRUGS). Virtual in-depth interviews were also performed between July-August 2022 using a semi-structured interview guide. All interviews were audio-recorded and transcribed verbatim. Qualitative data were analysed using a thematic analysis approach guided by Bailey and colleagues' model of medication self-management.

    RESULTS: The mean DRUGS summary score was 96.86 [standard deviation (SD) 3.74] with highest performance scores observed in medication access (100 %) and lowest performance score in medication identification (91.46 %). Informants were able to independently take their medications and they tended to organise their medication intakes according to mealtime even though some admitted missing medication doses due to forgetfulness. Informants had difficulties with recalling drug names, with little awareness of self-monitoring their own health conditions and the effects of medications. Misconceptions towards medications, difficulties in accessing medications, reduced mobility and worsening health conditions could potentially deter informants from safe and independent medication self-management. In contrast, trust in doctors and a desire to achieve treatment goal could motivate medication self-management.

    CONCLUSION: The findings revealed knowledge gaps among older adults with CF in identifying their medications and self-monitoring which warrant reinforcement by healthcare professionals to ensure chronic safe medication use. Future studies should evaluate strategies to enhance medication safety in terms of self-monitoring in individuals with CF.

    AIM: Several frailty assessment tools are currently used in clinics and research, however, there appears to be a lack of head-to-head comparisons between these tools among older adults in developing countries. This study compared the Cardiovascular Health Study, Study of Osteoporotic Fractures, the Tilburg Frailty Indicator and the Canadian Study of Health and Aging frailty assessment tools and evaluated performance of these individual frailty assessment tools with mortality.

    METHODS: This prospective cohort study utilized stratified simple random sampling to recruit 1614 participants from the Malaysian Elders Longitudinal Research aged above 55 years within the Klang Valley region from 2013 to 2015. Individual items for the frailty tools, alongside baseline physical and cognitive measures were extracted from the initial survey. Mortality data up to 31 December 2020 were obtained through data linkage from the death registry data obtained from the Malaysian National Registration Department.

    RESULTS: Data were available for over 1609 participants, age (68.92 ± 7.52) years and 57 % women, during recruitment. Mortality data revealed 13.4 % had died as of 31 December 2020. Five to 25 % of our study population fulfilled the criteria for frailty using all four frailty tools. This study found an increased risk of mortality with frailty following adjustments for potential factors of falls, total number of illnesses and cognitive impairment, alongside moderate to strong correlation and agreement between frailty tools.

    CONCLUSION: Frailty was associated with increased mortality. All four frailty assessment tools can be used to assess frailty within the Malaysian older adult population. The four available tools, however, may not be interchangeable.

    BACKGROUND: Prolonged life expectancy is associated with increased prevalence of chronic diseases. The aim of this study was to determine the different disability trajectories for the top ten leading causes of death in Taiwan .

    METHODS: A total of 2,431 participants aged 50-96 in 1996 from the Taiwan longitudinal study on aging (TLSA) who died from 1996 to 2016 were analyzed. Integration of Cause of Death Data and TLSA helped sort out participants who had died from the ten leading causes of death. The level of physical disability was evaluated with the Activities of Daily Living Scale (ADLs), ranging from 0 to 6 points, in 1996, 1999, 2003, 2007, and 2011. A multilevel model was used to investigate the levels and rates of change in disability development before death.

    RESULTS: The outcome of the research showed that the earliest group to experience physical limitation was individuals living with diabetes. The groups with the highest ADL scores were participants with diabetes, cerebrovascular disease, and hypertension-related diseases. Most groups reach ADL scores ≥ 1 (mild-level) during 4-6 years before death except chronic hepatitis and cirrhosis and injury.

    CONCLUSIONS: People who had died from the ten leading causes of death experienced different disability trajectories before death. The trajectory of the participants who had died from diabetes showed a unique pattern with the earliest occurrence and more severe deterioration in terms of development of disabilities. Disability trajectories provide a prediction of survival status for middle-aged and older adults associated with the ten leading causes of death.

    INTRODUCTION: Medical errors commonly occur in medical imaging departments. These errors are frequently influenced by patient safety culture. This study aimed to develop a suitable patient safety culture assessment tool for medical imaging departments.

    METHODS: Staff members of a teaching hospital medical imaging department were invited to complete the generic short version of the Safety Attitude Questionnaire (SAQ). Internal consistency and reliability were evaluated using Cronbach's α. Confirmatory factor analysis (CFA) was conducted to examine model fit. A cut-off of 60% was used to define the percentage positive responses (PPR). PPR values were compared between occupational groups.

    RESULTS: A total of 300 complete responses were received and the response rate was 75.4%. In reliability analysis, the Cronbach's α for the original 32-item SAQ was 0.941. Six subscales did not demonstrate good fit with CFA. A modified five-subscale, 22-item model (SAQ-MI) showed better fit (goodness-to-fit index ≥0.9, comparative fit index ≥ 0.9, Tucker-Lewis index ≥0.9 and root mean square error of approximation ≤0.08). The Cronbach's α for the 22 items was 0.921. The final five subscales were safety and teamwork climate, job satisfaction, stress recognition, perception of management and working condition, with PPR of 62%, 68%, 57%, 61% and 60%, respectively. Statistically significant differences in PPR were observed between radiographers, doctors and others occupational groups.

    CONCLUSION: The modified five-factor, 22-item SAQ-MI is a suitable tool for the evaluation of patient safety culture in a medical imaging department. Differences in patient safety culture exist between occupation groups, which will inform future intervention studies.

    Dementia affects the individual's functional ability including sexual activity. Limited understanding is available to support sexual health practices. This meta-synthesis review aimed to identify the gaps in the study of sexuality in dementia using the Model of Human Occupation (MOHO). Electronic searches utilizing six databases for existing articles involving persons living with dementia, care partners, and healthcare workers. The result showed that available studies primarily explored sexuality from the viewpoint of spouses of persons living with dementia. The volition domain of MOHO was the most explored provides a deeper understanding of volition on intrinsic perspective on sexuality in people with dementia. The environment domain was the least explored, highlighting healthcare professionals' need for social support and training. The topic of sexuality remains sensitive, limiting the availability of evidence-based interventions in this area.

    Osteoarthritis (OA) exacerbates skeletal muscle functioning, leading to postural instability and increased falls risk. However, the link between impaired physical function, OA and falls have not been elucidated. We investigated the role of impaired physical function as a potential mediator in the association between OA and falls. This study included 389 participants [229 fallers (≥2 falls or one injurious fall in the past 12 months), 160 non-fallers (no history of falls)], age (≥65 years) from a randomized controlled trial, the Malaysian Falls Assessment and Intervention Trial (MyFAIT). Physical function was assessed using Timed Up and Go (TUG) and Functional Reach (FR) tests. Knee and hip OA were diagnosed using three methods: Clinical, Radiological and Self-report. OA symptom severity was assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC). The total WOMAC score was categorized to asymptomatic, mild, moderate and severe symptoms. Individuals with radiological OA and 'mild' overall symptoms on the WOMAC score had reduced risk of falls compared to asymptomatic OA [OR: 0.402(0.172-0.940), p = 0.042]. Individuals with clinical OA and 'severe' overall symptoms had increased risk of falls compared to those with 'mild' OA [OR: 4.487(1.883-10.693), p = 0.005]. In individuals with radiological OA, mild symptoms appear protective of falls while those with clinical OA and severe symptoms have increased falls risk compared to those with mild symptoms. Both relationships between OA and falls were not mediated by physical limitations. Larger prospective studies are needed for further evaluation.

    AIM: Cytokines released from chronically-activated microglia could result in neuroinflammation. An accurate profile of the relationship between cytokines and Alzheimer's disease (AD) pathogenesis, as well as the patterns of these inflammatory mediators in AD patients could lead to the identification of peripheral markers for the disease. The present study was undertaken to identify pro- and anti-inflammatory cytokines associated with AD in the Malaysian population.

    METHODS: Further to informed consent from 39 healthy subjects and 39 probable AD patients, 8.5 mL of peripheral blood was collected and serum was extracted. The differential levels of 12 serum cytokines extracted from peripheral blood samples were measured using Procarta Multiplex Cytokine and enzyme-linked immunoassay kits. Concentrations of cytokines were measured at 615 nm using a fluorometer.

    RESULTS: Except for tumor necrosis factor-α, all classical pro-inflammatory cytokines (interleukin [IL]-1β, IL-6, IL-12 and interferon-γ) were found to be significantly upregulated (P 53.65 ρg/mL and <9.315 ρg/mL, respectively).

    CONCLUSIONS: Both the non-classical pro-inflammatory CXCL-10 and anti-inflammatory IL-13 cytokines showed promising potential as blood-based cytokine biomarkers for AD. This is the first study of non-classical cytokine profiles of Malaysian AD patients. Geriatr Gerontol Int 2017; 17: 839-846.

    To evaluate the utility of blood pressure variability (BPV) calculated using previously published and newly introduced indices using the variables falls and age as comparators.While postural hypotension has long been considered a risk factor for falls, there is currently no documented evidence on the relationship between BPV and falls.A case-controlled study involving 25 fallers and 25 nonfallers was conducted. Systolic (SBPV) and diastolic blood pressure variability (DBPV) were assessed using 5 indices: standard deviation (SD), standard deviation of most stable continuous 120 beats (staSD), average real variability (ARV), root mean square of real variability (RMSRV), and standard deviation of real variability (SDRV). Continuous beat-to-beat blood pressure was recorded during 10 minutes' supine rest and 3 minutes' standing.Standing SBPV was significantly higher than supine SBPV using 4 indices in both groups. The standing-to-supine-BPV ratio (SSR) was then computed for each subject (staSD, ARV, RMSRV, and SDRV). Standing-to-supine ratio for SBPV was significantly higher among fallers compared to nonfallers using RMSRV and SDRV (P = 0.034 and P = 0.025). Using linear discriminant analysis (LDA), 3 indices (ARV, RMSRV, and SDRV) of SSR SBPV provided accuracies of 61.6%, 61.2%, and 60.0% for the prediction of falls which is comparable with timed-up and go (TUG), 64.4%.This study suggests that SSR SBPV using RMSRV and SDRV is a potential predictor for falls among older patients, and deserves further evaluation in larger prospective studies.

    Pain assessment in older individuals with cognitive impairment is challenging. Evidence on the performance of pain assessment tools in this population remains limited. The aim of this study was to evaluate the performance of self-reported pain, nurse-reported pain, and observational pain tools among older patients with cognitive impairment using a prospective observational design. In all, 152 older individuals admitted to the acute geriatric ward were recruited through convenience sampling. Three methods of pain assessment were compared: self-reported pain (SRP), observational pain using the Pain Assessment in Advanced Dementia (PAINAD) tool, and nurse-reported pain (NRP). Cognition and mood were assessed with the Mini-Mental State Examination (MMSE) and the 15-item Geriatric Depression Scale (GDS-15). There was moderate agreement between SRP and PAINAD (k = 0.438) and fair agreement between SRP and NRP (k = 0.263). There was statistically significant correlation between SRP and GDS-15 (r = 0.382, p

    Introduction: Anaemia is common among the elderly, yet it remains an underresearched clinical condition. This study investigates ethnic differences in prevalence of anaemia and identifies potential factors associated with anaemia in the elderly.
    Methods: Data from the National Health & Morbidity Survey (NHMS) 2015 conducted by Ministry of Health was analyzed. Haemoglobin levels were measured using point-of-care testing, HemoCue® Hb 201+ System©, from consenting individuals. Demographic information and other clinical information were obtained through a structured questionnaire. Descriptive and multivariate analyses were conducted and significant results were presented as adjusted odds ratio.
    Results: A total of 3794 participants aged 60 years and older responded to the anaemia module with a response rate of 93.7%. 64.0% of respondents were of Malay ethnicity, 21.6% were Chinese, 6.1% were Indians, and 8.3% were of other ethnicities. The overall prevalence of anaemia among older people was 35.3%. The highest prevalence of anaemia was found among respondents of Indian ethnicity (45.5%). The Indian (aOR: 1.72; 95% CI 1.26-2.34) and Malay (aOR: 1.25; 95% CI 1.04-1.49) ethnic groups were more likely to be anaemic in comparison to those of Chinese ethnicity. Anaemia in older people was also associated with increasing age, history of hospital admission, and the presence of diabetes mellitus.
    Conclusion: Anaemia in the elderly is associated with Indian and Malay ethnicities, increasing age, hospitalization, and diabetes. Our study has identified important information on a common condition which will guide and assist future studies in reducing the burden of anaemia.

    Objective: Alzheimer's disease (AD), the commonest form of dementia which is characterized by progressive decline in cognitive function, can only be definitively diagnosed after death. Although biomarkers may aid diagnosis, currently available AD biomarkers, which are predominantly based on cerebrospinal fluid and neuroimaging facilities, are either invasive or costly. Blood-based biomarkers for AD diagnosis are highly sought after due to its practicality at the clinic. This study was undertaken to determine the differential protein expression in plasma amongst Malaysian AD, mild cognitive impairment (MCI) and non-AD individuals. Methods: A proteomic approach which utilized two-dimensional differential in gel electrophoresis (2 D DIGE) was performed for blood samples from 15 AD, 14 MCI and 15 non-AD individuals. Results: Mass spectrometry (MS)-based protein identification via MALDI ToF/ToF showed that fibrinogen-β-chain (spot 64) and fibrinogen-γ-chain (spot 91) with differential expression ratio >1.5 were significantly upregulated (p

    To palliate suffering, understanding the circumstances leading to suffering and its amelioration could be helpful. Our study aimed to explore contributing and relieving factors of suffering in palliative care. Adult palliative care stage III or IV cancer in-patients were recruited from University of Malaya Medical Centre. Participants recorded their overall suffering score from 0 to 10 three times daily, followed by descriptions of their contributing and relieving factors. Factors of suffering were thematically analysed with NVIVO. Descriptive data were analysed with SPSS. 108 patients participated. The most common contributing factor of suffering was health factor (96.3%), followed by healthcare factor (78.7%), psychological factor (63.0%) and community factor (20.4%). The most common relieving factor was health factor (88.9%), followed by psychological factor (78.7%), community factor (75.9%) and healthcare factor (70.4%). Self-reported assessment of suffering offers a rapid approach to detect bothering issues that require immediate attention and further in-depth exploration.

    BACKGROUND: The ageing skin is more susceptible to pruritic dermatoses, which are associated with adverse psychosocial effects and reduced quality of life among older adults. This cross-sectional study aimed to identify the burden of pruritus and factors associated with its presence and severity among older adults recruited to the Malaysian Elders Longitudinal Research study.

    METHODS: Seven hundred seventy individuals aged 55 years (lower age limit) and above were interviewed as to whether they experienced pruritus during the preceding week and the locations involved if present. The association between generalised pruritus, sleep quality, and major systemic risk factors were explored.

    RESULTS: 5.97% of respondents reported generalised pruritus. Generalised pruritus was associated with poorer sleep quality, with Pittsburgh Sleep Quality Index score above 6. Mean haemoglobin level was lower in subjects with generalised pruritus (13.14 g/dL) but there was no significant difference in the frequency of generalised pruritus and severe generalized pruritus between subjects with clinically defined anaemia. Also, there were no significant associations between other major systemic risk factors and generalised pruritus in this population-based study. There was no association between generalised pruritus with depression, anxiety or stress.

    CONCLUSION: The negative effect of pruritus on sleep quality suggests a possible deleterious effect of pruritus on health and quality of life. Further prospective research on the longer-term effects of pruritus on health status is now warranted. (222 words).

    Reduced peak expiratory flow is a common physiological change in older individuals and age is an important predictor for sarcopenia. We analyzed nationwide survey data to determine the relationship between peak expiratory flow rate and sarcopenia in older Indonesians. Community-dwelling Indonesian individuals aged ≥60 years (n = 2422; mean age = 67.21 y) from the fifth-wave data of the Indonesian Family Life Survey was selected. Sarcopenia was diagnosed based on handgrip strength, gait speed, and appendicular skeletal muscle mass measurements. Peak expiratory flow rates (PEFRs) were categorized according to their percentage of predicted flow rates as <50%, 50% to 80%, and >80%. Confounders previously determined to be associated with sarcopenia occurrence were included. Sarcopenia prevalence was 50.25%. After adjustment for confounders, PEFRs of <50% and 50% to 80% were associated with an increased sarcopenia risk (odds ratio = 5.22 and 1.88, respectively) compared with PEFRs of >80%. Poor lung function was independently associated with sarcopenia occurrence. Future studies should explore the usefulness of PEFR as a risk factor of sarcopenia.

    BACKGROUND: Rapid population aging occurring in developing nations necessitates innovation to ensure we continue to gain ground on aging research despite pandemic threats. While developed nations have resorted to virtual communications, this is challenging in developing nations due to poor internet connectivity and digital literacy.

    OBJECTIVES: The aim of this study was to determine the feasibility of virtual data collection for a longitudinal study of aging assessing cognitive frailty in a middle-income Southeast Asian country.

    METHODS: The Transforming Cognitive Frailty into Later-Life Self-Sufficiency (AGELESS) longitudinal study of aging involved community-dwelling participants aged 60 years and above. A semi-structured focus group discussion was conducted via videoconferencing with selected representatives from existing participants. The survey instrument was compiled during a hybrid meeting and refined using a virtual Delphi process involving 51 AGELESS investigators. The final draft survey and recruitment strategy were then piloted among selected participants.

    RESULTS: Twelve individuals participated in the virtual focus group interview. Smartphone, tablet computer, laptops, and desktop personal computers were used for information gathering, communication, banking, shopping, leisure, religion, and education, within this group. The survey instrument was redacted from 362 items in 18 sections to 141 items in 12 sections through 3 virtual Delphi rounds facilitated by email, social media messaging, and videoconferencing which attracted 213 comments.
