    Cognitive impairment and dementia-related diseases develop several years before moderate or severe deterioration in cognitive function occurs. Nevertheless, most dementia cases, especially in low- and middle-income countries, remain undiagnosed because of limited access to affordable diagnostic tools. Additionally, the development of accessible tools for diagnosing and predicting cognitive impairment has not been extensively discussed in the literature. The objective of this study is to develop a cost-effective and highly accessible machine learning model to predict the risk of cognitive impairment for up to five years before clinical insight. We utilized easily accessible data from the National Alzheimer's Coordinating Center (NACC) Uniform Data Set (UDS) to train and evaluate various machine learning and deep learning models. A novel algorithm was developed to facilitate the selection of cost-effective models that offer high performance while minimizing development and operational costs. We conducted various assessments, including feature selection, time-series analyses, and external validation of the selected model. Our findings indicated that the Support Vector Machine (SVM) model was preferred over other high-performing neural network models because of its computational efficiency, achieving F2-scores of 0.828 in cross-validation and 0.750 in a generalizability test. Additionally, we found that demographic and historical health data are valuable for early prediction of cognitive impairment. This study demonstrates the potential of developing accessible solutions to predict cognitive impairment early using accurate and efficient machine learning models. Future interventions should consider creating cost-effective assessment tools to support global action plans and reduce the risk of cognitive impairment.

    Due to the limited hydrophobic properties of porcelain insulators, applying anti-pollution flashover coatings is crucial to enhance their functionality. This research outlines a classification system for assessing contamination levels on 22 kV porcelain insulators, both with and without coatings. It synthesizes six classification criteria derived through both numerical simulations and experimental studies to effectively gauge contamination severity. The study examined insulators treated with Room Temperature Vulcanizing (RTV) silicone under three different conditions: uncoated, partially coated, and fully coated. Additionally, the research assessed the effects of humidity on these polluted insulators to understand environmental impacts on their performance. The criteria, which are the flashover voltage (x1), fifth to third harmonics of leakage current (x2), maximum electric field (x3), total harmonic index (x4), insulation resistance (x5) and dielectric loss (x6), were proposed for evaluating the insulator's string condition. The finite element method (FEM) was used to simulate an electric field. Then, based on the proposed criteria, the performances of the Random Forest (RF), Support Vector Machine (SVM), K-Nearest Neighbor (KNN), and Multi-layer Perceptron (MLP) have been trained and compared to classify polluted insulator conditions with and without coating. The established criteria facilitate precise monitoring of the condition of high-voltage insulators, ensuring quick and effective responses that support the stability of the electrical power system.

    BACKGROUND: Small for gestational age (SGA) and large for gestational age (LGA) are designations given to neonates based solely on birthweight, with no distinction made for maternal height. However, there is a possibility that maternal height is significantly correlated with neonatal birthweight, and if so, SGA and LGA cutoffs specific to maternal height may be a more precise and useful tool for clinicians. To explore this possibility, we analyzed the association between maternal height and ethnicity and neonate birthweight in women with low-risk, 37- to 40-week gestation, singleton pregnancies who gave birth vaginally between 2010 and 2017 (n = 354,488). For this retrospective cohort study, we used electronic obstetric records obtained from the National Obstetrics Registry in Malaysia.

    METHODS: National Obstetric Registry (NOR) data were used to calculate the 10th and 90th birthweight percentiles for each maternal height group by gestational age and neonatal sex. Multiple linear regression models, adjusted for maternal age, weight, parity, gestational age, and neonatal sex, were used to examine the association between neonate birthweight and maternal ethnicity and height. The following main outcome measures were assessed: small for gestational age (<10th percentile), large for gestational age (>90th percentile), and birthweight.

    RESULTS: The median height was 155 cm (IQR, 152-159), with mothers of Chinese descent being the tallest (median (IQR): 158 cm (154-162)) and mothers of Orang Asli (Indigenous) descent the shortest (median (IQR): 151 cm (147-155)). The median birthweight was 3000 g (IQR, 2740-3250), with mothers of Malay and Chinese ethnicity and Others having, on average, the heaviest babies, followed by other Bumiputeras (indigenous) mothers, mothers of Indian ethnicity, and lastly, mothers of Orang Asli ethnicity. For infants, maternal age, height, weight, parity, male sex, and gestational age were positively associated with birthweight. Maternal height had a positive association with neonate birthweight (B = 7.08, 95% CI: 6.85-7.31). For ethnicity, compared with neonates of Malay ethnicity, neonates of Chinese, Indian, Orang Asli, and other Bumiputera ethnicities had lower birthweights.

    CONCLUSION: Birthweight increases with maternal height among Malaysians of all ethnicities. SGA and LGA cutoffs specific to maternal height may be useful to guide pregnancy management.

    Photobiomodulation (PBM) holds promise as a therapy modality, but its applicability is hindered by the lack of a quantitative model to predict the optimal dose for all forms of PBM. This study investigated the optimal PBM parameters for 532 nm green laser irradiation on SHSY5Y neuroblastoma cells, a commonly used in vitro model for neurodegenerative disease studies. A two-tailed, two sample t-test with equal variance was used to obtain the p-values and statistical significance. There are 3 sets of parameters showing significant ( p < 0 . 01 ) positive percentage biostimulation. 160 m W , 15 m i n produce a percentage biostimulation of ( 9 ± 10 ) % ; 180 m W , 5 m i n produce a percentage biostimulation of ( 19 ± 7 ) % ; and ( 200 m W , 5 m i n ) produce a percentage biostimulation of ( 9 ± 2 ) % . The highest significant ( p < 0 . 01 ) percentage bioinhibition observed is for 220 m W , 15 m i n (dose: 1008 J / c m 2 ) producing a bioinhibition of ( 54 ± 1 ) % . After identifying several parameters that produce noticeable photobiological effects (biostimulation and bioinhibition), this study compared the reaction of undifferentiated and differentiated SHSY5Y cells to laser irradiation and found that undifferentiated SHSY5Y cells shows greater photobiological effect from 532 nm laser irradiation ( p < 0 . 01 ) . This study demonstrated the differentiation-dependant photobiological effect of SHSY5Y in 532 nm laser PBM. This shows that considerations on the differentiation state of cells is important in PBM studies. The hypothesis of difference in intracellular reactive oxygen species (ROS) accumulation from laser irradiation can serve as a versatile explanation of the observed difference in photobiological effect. Further investigation into the role of ROS as a mediator of various photobiological effects from laser of different wavelengths is warranted.

    BACKGROUND: Low income communities are vulnerable to non-communicable diseases (NCDs), which affect their economy and disability status. An effective approach to address the NCD burden is through the multidimensional concept of health-promoting lifestyle. Another preferred approach by the population worldwide for NCD treatment is natural health product (NHP). Studies on NHP and health-promoting lifestyle among this vulnerable population, specifically the low-income urban community, are limited. Therefore, this study, aimed at investigating the NHP knowledge and health-promoting lifestyle, and to determine the factors associated with health-promoting lifestyle in a low income urban community in Cheras, Kuala Lumpur. This study has focused on sociodemographic characteristics, annual health monitoring activities, and health status, which are modifiable and non-modifiable factors.

    METHODS: Phase 1 of the study involves developing the Malay-version NHP knowledge questionnaire, whereas Phase 2 involves a cross-sectional study of 446 randomly selected low-income respondents to determine their level of health-promoting lifestyle and the associated factors. The respondents' sociodemographic, socioeconomic, health monitoring activity, health status, and NHP knowledge data were obtained using the newly developed Malay-version NHP questionnaire and the Health-Promoting Lifestyle Profile II (HPLP II) questionnaire. The independent variables include sociodemographic status, annual health monitoring activities, health status and NHP knowledge were analysed using simple and multiple linear regression.

    RESULTS: In this study, the 10-item NHP knowledge questionnaire developed in the Malay version contains two domains [safe use (eight items) and point of reference (two items)] (total variance explained: 77.4%). The mean of NHP knowledge score was 32.34 (standard deviation [SD] 7.37). Meanwhile, the mean score of health-promoting lifestyle was 109.67 (SD 25.01). The highest and lowest scores of health-promoting lifestyles are attributed to spiritual growth and physical activity, respectively. Ethnicity is associated with a higher health-promoting lifestyle level, same goes to the occupational status - NHP knowledge interaction. "Unclassified" education status and annual blood glucose level monitoring are associated with a lower level of health-promoting lifestyle.

    CONCLUSION: A new questionnaire in Malay version was developed to measure NHP knowledge. Compared to other subpopulations, the respondents' health-promoting lifestyle levels in this study were low, associated with ethnicity, education status, and health monitoring activities. The findings provided insight into the interaction between NHP knowledge and occupational status, which is associated with a higher health-promoting lifestyle level. Accordingly, the future health-promoting lifestyle intervention programmes in healthcare delivery should target these factors.

    Breast cancer remains a significant global health challenge, spurring ongoing investigations into innovative treatment approaches. Low-level laser therapy (LLLT) has emerged as a promising non-invasive therapeutic avenue of interest. This research delves into the impact of LLLT on the cytotoxicity of the MCF-7 breast cancer cell line, employing lasers emitting various wavelengths. The objective is to assess whether diverse LLLT wavelengths elicit disparate cytotoxic responses, shedding light on LLLT's potential as a targeted breast cancer treatment. MCF-7 cell cultures were subjected to lasers of varying wavelengths, including blue (473 nm), red (660 nm), and near-infrared (780 nm). Each wavelength was delivered at four different power levels: 10, 25, 45, and 65 mW, with exposure durations of 60, 300, 600, and 900 s. Cellular responses, encompassing factors such as cell viability, and cytotoxicity were assessed using WST-1 assays technique. Statistical analysis was performed to discern the wavelength-specific impacts of low-level laser therapy (LLLT) on MCF-7 cells. The study revealed that the blue laser had the least noticeable adverse impact on MCF-7 breast cancer cell lines, leading to the highest cell survival rate of 107.62% after 24 h. The most severe toxicity occurred when the laser was used at 45 mW for 900 s, resulting in cell viability ranging from 81.85% to 107.62%. As for cell viability after exposure to the red laser, the mildest harmful effect was observed at 45 mW power for 60 s, resulting in a cell survival rate of 147.62%. Conversely, the most significant toxic response occurred at 10 mW power for 60 s, resulting in a cell viability of 91.56%. In contrast, when employing infrared laser irradiation, the least substantial cytotoxic effect on MCF-7 cells was observed at 10 mW power for 600 s, resulting in the highest cell viability of 109.37% after 24 h. The most pronounced cytotoxic effect was observed by infrared laser (780 nm) at 25 mW power for 900 s, leading to the lowest viability of 32.53%.

    OBJECTIVE: To determine whether a chemokine receptor type 2 antagonist, DMX-200 (repagermanium), in combination with an angiotensin receptor blocker, candesartan, improves clinical outcomes in people with COVID-19.

    DESIGN: Prospective, multicentre, double-blind, placebo-controlled trial.

    SETTING: Ten acute care hospitals in India.

    PARTICIPANTS: Adults <65 years old intended for hospital admission with moderate/severe COVID-19 disease (respiratory rate ≥24 breaths per minute or oxygen saturation ≤93% on room air).

    INTERVENTION: DMX-200 120 mg two times per day, or placebo, on background of titratable candesartan commencing at 4 mg two times per day, for 28 days.

    MAIN OUTCOME MEASURES: The primary endpoint was COVID-19 disease severity on a modified WHO Clinical Progression Scale (WHO scale) on day 14. Secondary outcomes included the WHO scale at days 28, 60, 90 and 180; intensive care unit (ICU) admission, respiratory failure or death within 28 days; length of hospitalisation; and requirement for ventilatory support or dialysis.

    RESULTS: Between December 2021 and August 2022, 518 people were screened, with 49 randomised to DMX-200 or placebo on a background of candesartan. The study was terminated early due to recruitment barriers, including an external requirement to restrict enrolment to adults <65 years old, contributing to a 91% screen failure rate. The median WHO Clinical Progression Scale (WHO scale) score at day 14 for both groups was 1 (IQR 1-1), indicating most participants were discharged with no limitations on activities by this time. Formal comparison was not performed due to the small sample size. One participant receiving DMX-200 died of COVID-19 disease progression. No participants required ICU admission, ventilation or dialysis. Median length of hospitalisation in both groups was 6 days (IQR 6-7 days). WHO scale scores were similar at 28, 60, 90 and 180 days.

    CONCLUSION: Due to recruitment barriers, the study was unable to determine whether DMX-200 improves clinical outcomes in people with COVID-19.

    BACKGROUND: Various barriers lead to a shortage of organs for transplantation in Malaysia. One drive to improve the organ donation rate operates through future healthcare practitioners and practitioner advocacy. This scoping review was carried out to establish and summarise findings about organ donation-related articles among the public, health sciences students and health personnel. A further aim was to synthesise the latest data on knowledge and attitudes towards organ donation in the Malaysian population.

    METHODS: PubMed, Scopus, Google Scholar and the Malaysian Medical Repository (MyMedR) were used for a search conducted up to May 2022. Relevant search terms included 'Organ donation' and 'Malaysia'. Journal articles related to knowledge, attitudes and intention were grouped under the general public and health science. Students and health personnel were included. Eligible studies were reviewed by two independent reviewers. Any disagreements were resolved by consensus with a third reviewer.

    RESULTS: The 31 included articles revealed an increased level of awareness among the public regarding organ donation. The analysis identified that nonrecognition of brainstem death (38.5%), no knowledge of how to contact the Organ Transplant Coordinator (82.3%) and never approaching the families of a potential donor (63.9%) led to a lack of confidence among healthcare practitioners to promote organ donation.

    CONCLUSION: The shortage of organ donors is the result of the failure to identify the expected donor, obtain consent and procure the organs due to the passivity of Malaysian health professionals in promoting the organ donation process.

    Telepsychiatry formed part of the Australian mental health response to COVID-19, but relevant reviews pre- and post-pandemic are sparse. This scoping review aimed to map the literature on telepsychiatry in Australia and identify key research priorities. We searched databases (Medline, PubMed, PsycINFO, Scopus, Web of Science, EBSCO Psychology & Behavioral Sciences Collection, Proquest databases, and Cochrane Central Register of Controlled Trials) and reference lists from January 1990 to December 2022. Keywords included telepsychiatry, videoconferencing, telephone consultation, psychiatry, mental health, and Australia. Two reviewers independently screened titles, abstracts, and full texts. We identified 96 publications, one-third of which appeared since 2020. Extracted data included article types, service types, usage levels, outcome measures, perceptions, and research gaps. Most publications were quantitative studies (n = 43) and narrative reports of services (n = 17). Seventy-six papers reported mostly publicly established services. Videoconferencing alone was the most common mode of telepsychiatry. There was increased use over time, with the emergence of metropolitan telepsychiatry during the pandemic. Few papers used validated outcome measures (n = 5) or conducted economic evaluations (n = 4). Content analysis of the papers identified perceptions of patient (and caregiver) benefits, clinical care, service sustainability, and technology capability/capacity. Benefits such as convenience and cost-saving, clinical care issues, and implementation challenges were mentioned. Research gaps in patient perspectives, outcomes, clinical practice, health economics, usage patterns, and technological issues were identified. There is consistent interest in, and growth of, telepsychiatry in Australia. The identified perception themes might serve as a framework for future research on user perspectives and service integration. Other research areas include usage trends, outcome measures, and economic evaluation.

    Recently, wastewater-based epidemiology (WBE) research has experienced a strong impetus during the Coronavirus disease 2019 (COVID-19) pandemic. However, a few technical issues related to surveillance strategies, such as standardized procedures ranging from sampling to testing protocols, need to be resolved in preparation for future infectious disease outbreaks. This review highlights the study characteristics, potential use of WBE and overview of methods, as well as methods utilized to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) including its variant in wastewater. A literature search was performed electronically in PubMed and Scopus according to PRISMA guidelines for relevant peer-reviewed articles published between January 2020 and March 2022. The search identified 588 articles, out of which 221 fulfilled the necessary criteria and are discussed in this review. Most global WBE studies were conducted in North America (n = 75, 34 %), followed by Europe (n = 68, 30.8 %), and Asia (n = 43, 19.5 %). The review also showed that most of the application of WBE observed were to correlate SARS-CoV-2 ribonucleic acid (RNA) trends in sewage with epidemiological data (n = 90, 40.7 %). The techniques that were often used globally for sample collection, concentration, preferred matrix recovery control and various sample types were also discussed. Overall, this review provided a framework for researchers specializing in WBE to apply strategic approaches to their research questions in achieving better functional insights. In addition, areas that needed more in-depth analysis, data collection, and ideas for new initiatives were identified.

    The ureteral access sheath (UAS) has been a boon and a bane in flexible ureteroscopy (FURS), with its merits and demerits well established. Its design and dimensions were instrumental in reshaping the way flexible scopes were used and were key adjuncts to establishing retrograde intrarenal surgery (RIRS) as a standard of care in the endourological management of renal stones. With the ever-changing landscape of RIRS over the decades shaped by technological advancements in lasers and flexible scopes, the UAS has also continuously evolved. The utility of suction in endourology has recently changed the way RIRS is performed and is a game changer for FURS outcomes. With strong clinical and experimental evidence to support its use, the UAS has undergone a transformative change in the recent past, with its ability to monitor intrarenal pressure and provide a superior vacuum-cleaner effect that improves the trifecta of RIRS, namely an improved single-stage stone-free rate (SFR), minimise complications, and reduce reinterventions. Our comprehensive review outlines the key clinical and experimental evidence and traces the developments that were key to modifying the traditional UAS into a flexible and navigable suction ureteric access sheath (FANS) and highlights how the design and modifications, in turn, influence the ability to push the boundaries of RIRS.

    INTRODUCTION: Various evaluation tools have been developed to track the growth of auditory-related behaviours of children with hearing loss during intervention. However, the reliability and validity of currently available outcome measures remain uncertain due to the lack of information on their psychometric properties. A lack of reliable outcome measures may jeopardise intervention quality and affect these children's listening skills progression. This scoping review aims to explore the mechanics of producing or developing an outcome measure either completely new or adapted from the original version that is considered as having robust statistical properties.

    MATERIALS AND METHODS: A scoping review was conducted across four databases (PubMed, ScienceDirect, Scopus and Google Scholar). The included articles were written in English, published between January 2010 and June 2023, and specific to predefined keywords. Two independent reviewers screened and selected the final papers using the PRISMScR checklist. A code framework was created to extract information about the publications and conducted by one reviewer. The results were reported using descriptive statistics and narrative synthesis.

    RESULTS: The final analysis were conducted on 22 articles out of 452 articles screened. The review identified seven outcome measures presented in various languages. The outcome measures found were the Auditory Behaviour in Everyday Life (ABEL), Functional Listening Index for Paediatric (FLI-P), Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS), Integrated Scales of Development (ISD), LittlEARS Auditory Questionnaire (LEAQ), Parent's Evaluation of Aural/Oral Performance in Children (PEACH), Parent's Evaluation of Aural/Oral Performance in Children Diary (PEACH Diary), Teachers' Evaluation of Aural/Oral Performance in Children (TEACH) and Parent's Evaluation of Aural/Oral Performance in Children Plus (PEACH+). A total of 13 studies focused on translating, adapting and validating an outcome measure while the remaining investigations validated either the translated or original version of the outcome measures. All original instruments were developed in English and among Western culture, except for the LEAQ which was designed in the German language and for the German population. The outcome measures identified were translated and adapted into Spanish, Turkish, Persian, Hebrew, Arabic, Malay, Yoruba, Polish, Swedish, Hindi, Portuguese, Kannada and Mandarin.

    CONCLUSION: All studies performed an extensive evaluation of psychometric properties and feasibility studies to produce an excellent quality of auditory-related behaviour outcome measure for clinical use with the intended population. A new outcome measure, FLI-P, was found to be clinically useful for the primary provider of learning to listen and spoken language training for children with hearing impairment in Malaysia, i.e., the speech-language therapists.

    PURPOSE OF REVIEW: Kratom plant, products derived from the plant, and plant phytochemicals are of great interest among researchers, clinicians, and consumers. However, there is a paucity of rigorously collected scientific data on their risk/safety profile and public health impact. This scoping review discusses original research articles published between 2022 and 2023. It focuses on identifying publication gaps on topics related to epidemiology, public health, and risk/safety profiles comparing evidence collected by researchers from Southeast Asia and the West.

    RECENT FINDINGS: Our review of the Scopus database identified a total of 55 publications, including clinical case reports and case series reports, surveys, studies enrolling human participants, and publications based on large-scale national surveys or large-scale national or international health system database records.

    SUMMARY: Overall, there is dearth of reliable data on key epidemiological factors, including the prevalence rates, and on objective and reliable indices of the risk/safety profiles. Rigorous and systematic studies including improved epidemiological surveillance, human laboratory, and controlled clinical studies are urgently needed to advance our understanding of public health consequences of consuming kratom and kratom-derived products and to improve our understanding of their risk/safety profile and additional analytical studies to better inform development of needed regulatory oversight.

    BACKGROUND: Spinal cord injury (SCI) is a devastating condition that often leads to significant impairments in physical function, leading to disability and mental health disorders. Hence, understanding the prevalence of SCI and the relationship between physical activity and mental health in individuals with SCI is crucial for informing rehabilitation strategies and optimizing outcomes.

    OBJECTIVE: This study aims to comprehensively analyze existing research on the link between physical activity and mental health and identify the level of physical activity and mental health status, the barriers to physical activity, and SCI's impacts on psychological well-being in individuals with SCI.

    METHODS: An electronic search strategy will be used to identify prevalence studies published since 1993 in health-related databases such as PubMed, MEDLINE, COCHRANE Library, and Wiley Library using the following query: "Spinal Cord Injury" OR "Paraplegia" OR "Tetraplegia" AND "Physical Activity" OR "Exercise" AND "Mental Health" OR "Mental Illness" OR "Mental Disorder." Bibliographies of primary studies and review articles meeting the inclusion criteria will be searched manually to identify further eligible studies. The risk of bias in the included studies will be appraised using the Joanna Briggs Institute checklist for prevalence studies by 2 review authors. Any disagreement will be resolved by reaching a consensus.

    RESULTS: Funding was received in October 2023, data collection will commence in July 2024, and the results are expected by 2025. We will summarize the selection of the eligible studies using a flowchart. The data from the studies will be extracted and tabulated. This scoping review will be published in a peer-reviewed journal in accordance with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines.

    CONCLUSIONS: This scoping review underscores the complex relationship between physical activity and mental health among individuals with SCI, highlighting the level of physical activity and mental health status, barriers to physical activity engagement, and psychological implications. Understanding these dynamics is crucial in devising tailored interventions aimed at enhancing mental well-being. This synthesis of evidence emphasizes the need for personalized strategies to promote physical activity, addressing unique challenges faced by this population to foster improved mental health outcomes and overall quality of life.

In round 1, panellists nominated population groups least able to access refractive error services, and strategies to improve access. Responses were summarised and presented in round 2, where panellists ranked the groups (by extent of difficulty and size) and strategies (in terms of reach, acceptability, sustainability, feasibility and equity). Groups and strategies were scored according to their rank within each sub-region.

    RESULTS: Seventy five people from 17 countries completed both rounds (55% women). Regional differences were evident. Indigenous peoples were a priority group for improving access in Australasia and Southeast Asia, while East Asia identified refugees and Oceania identified rural/remote people. Across the five sub-regions, reducing out-of-pocket costs was a commonly prioritised strategy for refraction and spectacles. Australasia prioritised improving cultural safety, East Asia prioritised strengthening school eye health programmes and Oceania and Southeast Asia prioritised outreach to rural areas.

    CONCLUSION: These results provide policy-makers, researchers and funders with a starting point for context-specific actions to improve access to refractive error services, particularly among underserved population groups who may be left behind in existing private sector-dominated models of care.

    The intersection of gerontology and public health is increasingly vital due to the global aging population and its implications for health systems. This scoping review aims to map existing literature on gerontology within public health, identify current perspectives, and evaluate interventions tailored to the needs of older adults. A systematic search was performed using predefined keywords across multiple databases, including PubMed, Google Scholar, Scopus, and Web of Science. The review included 42 studies that employed various designs, all focusing on public health interventions targeting the aging population.  Key findings indicate a pressing need to integrate gerontological principles into public health practice, recognizing the heterogeneous nature of older adults and the significance of social determinants of health. Interventions ranged from preventive health measures and chronic disease management programs to health promotion activities and caregiver support, including the application of technology to improve health outcomes. However, there was a notable lack of research on diverse populations and mental health interventions. The review also uncovered critical gaps in the literature, such as economic barriers to care access and the necessity for comprehensive policies addressing the aging population's diverse needs. In conclusion, this review emphasizes the importance of a multidimensional approach to effectively addressing older adults' health needs. While several effective interventions exist, there is an urgent need to tackle identified gaps, particularly concerning diverse populations and mental health, to enhance overall health strategies for the aging demographic.

    OBJECTIVE: This systematic review aims to determine the global pooled prevalence of overweight and obesity among health care workers in the 6 World Health Organization regions.

    INTRODUCTION: The escalating prevalence of overweight and obesity among health care workers significantly affects both individual health and the quality of health care services. Understanding this global prevalence is crucial to be able to implement informed interventions and policies, and for the overall optimization of health care delivery.

    INCLUSION CRITERIA: Observational studies with prevalence data for overweight and obesity among health care workers in both private and public health care facilities will be considered for inclusion. Transparent documentation of anthropometric measurements and adherence to established overweight and obesity criteria by the WHO, Asia Pacific standards, or Asian criteria are required to be eligible for inclusion. The review will focus on observational study designs, including cross-sectional, survey, case-control, and cohort studies.

    METHODS: PubMed, Scopus, and Web of Science Core Collection will be searched for records with predefined keywords, including MeSH terms. Records found through hand-searching and reference lists will be added. Two researchers will independently screen studies, resolving any discrepancies with a third researcher. Standardized critical appraisal and data extraction forms will be used. If suitable, pooled prevalence for overweight and obesity based on the 6 WHO regions will be calculated using the DerSimonian-Laird random-effects model. Statistical analysis will be performed and publication bias will be assessed through funnel plot analysis using either Egger, Begg, or Harbord test.

    Organ donation and transplantation are integral components of modern medicine. This scoping review thoroughly explores the historical evolution, current status, and future prospects of organ donation and transplantation in Malaysia. Historically, Malaysia faced significant challenges in establishing a robust organ transplantation system, with various factors hindering organ donation efforts. Currently, Malaysia continues to struggle with stagnant donation rates despite collaborative efforts from various sectors. There is an urgent need to amend the 50-year-old Human Tissue Act to strengthen the legal framework for organ donation and address ethical concerns. Looking to the future, Malaysia could adopt a soft opt-out system and prioritize advancements in organ preservation techniques by exploring new sources of organs through the donation after circulatory death program. Continued efforts are necessary to enhance education programs for professionals and the public, dispelling myths about organ donation and effectively educating on the concepts of brain death. Malaysia strives to create a more accessible future for organ transplantation, aligning with the Sustainable Development Goals to reduce the burden of organ failure and improve the population's health and well-being.

    PURPOSE: The present study aimed to investigate how prior research of TTRPG revealed the benefits of TTRPG as a psychological intervention and how further studies can overcome the challenges and limitations of TTRPG in those previous studies.

    METHODS: The study used Scoping Review to explore the potential benefits of TTRPG. Three research questions were identified (1) the extent to which empirical research has been conducted regarding TTRPG as intervention, (2) the potential of TTRPG mentioned, and (3) the suggestions for future research. The study investigated the last 10 years (ie, 2013 to 2023) of research publications with all research methods included. The search focused on key terms of "Tabletop Role-playing Game", "TTRPG", "Dungeons and Dragons", and terms related to intervention. The databases used were in English and Indonesian and resulted in 109 papers but later eliminated due to various reasons until it became 51 papers to be reviewed.

    RESULTS: Of the 51 papers included for final analysis, majority are of exploratory approach (n = 35; eg, literature review and qualitative design studies), indicating that research in TTRPG is still at the emerging stage. Quantitative design studies (n = 12) and mixed-method design studies (n = 4) on TTRPG are the minority. Majority papers (n = 30) are published in the United States, only three papers published in the Asian context, indicating that TTRPG research in the Asian context is scarce.

    CONCLUSION: From existing literature, TTRPG provides benefits to promote cognitive and psychosocial skills, to prevent negative effects and stress, as well as to intervene in psychological problems such as social anxiety, depressive symptoms, and autism spectrum disorders. Further studies can explore the use of TTRPG in Asia-representing collectivistic culture, to employ different systems of TTRPG and to examine the effects of TTRPG using experimental design to overcome the limitations of prior studies.

    BACKGROUND: Digital health has been widely used in delivering healthcare, presenting emerging opportunities to overcome barriers to effective obesity care. One strategy suggested for addressing obesity involves a hybrid weight management intervention that incorporates digital health. This scoping review aimed to map existing evidence regarding hybrid weight management intervention.

    METHODS: PubMed, Scopus, Cochrane Library, and the Web of Science electronic databases were searched for studies published between January 1, 2012 and May 16, 2023, with language restricted to English. The focus was on controlled trials in which a hybrid weight management intervention was used in the intervention among overweight or obese adults. The scoping review framework followed Arksey and O'Malley's guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISM-P).

    RESULTS: Full-text article review in the screening stage resulted in a total of 10 articles being included for narrative synthesis. Almost two-third of the articles originated from the United States (60%), followed by Europe and Australia, each accounting for 20%. The most common hybrid weight management intervention type was the combination of face-to-face and telehealth (i.e. phone call/text messaging) (40%), closely followed by a combination email intervention (30%) and mHealth apps intervention (30%). Most of the face-to-face dietary interventions were delivered as a group counseling (80%), while some were conducted as individual counseling (20%). Most studies observed a positive effect of the hybrid weight management intervention on body weight (weight lost 3.9-8.2 kg), body mass index (decreased 0.58 kg/m2), waist circumference (decreased 2.25 cm), and physical activity level compared to standard care. Findings suggest a direct association between hybrid weight management interventions and weight loss. The weight loss ranged from 3.9 to 8.2 kg, with some evidence indicating a significant weight loss of 5% from baseline. There is a need to explore stakeholders' telehealth perspective to optimize the delivery of hybrid weight management interventions, thereby maximizing greatest benefits for weight management.
