Background: Work-related musculoskeletal disorders (WRMSDs) remain a major cause of occupational disability and productivity loss worldwide. Traditional statistical methods have identified numerous associated factors; however, they often struggle to capture complex non-linear relationships and interactions across multiple domains of risk. Machine learning (ML) offers an alternative analytical approach for modelling such multidimensional relationships. Methods: Following the PRISMA 2020 guidelines (PROSPERO: CRD420250605234), literature searches were conducted in Web of Science, Scopus, and PubMed for studies published between 2020 and 2025. Eligible studies applied ML methods to identify factors associated with WRMSDs using cross-sectional study designs. Included studies were appraised using the Joanna Briggs Institute Critical Appraisal Checklist for analytical cross-sectional studies. Results: Ten studies met the inclusion criteria, representing workers from healthcare, transport, manufacturing, and service sectors across Asia, Africa, and Europe. Frequently applied ML algorithms included random forest, support vector machine, and artificial neural networks, demonstrating strong internal discriminative performance (area under the receiver operating characteristic curve: 0.80–0.99), although the absence of external validation in several studies suggests a potential risk of overfitting. Commonly identified factors included age, sex, awkward posture, vibration exposure, prolonged working hours, stress, and burnout. Psychosocial factors, including post-traumatic stress disorder, job stress, and depression, were ranked among the most influential predictors within ML models. Conclusions ML models demonstrate strong capability in discriminating WRMSDs risk and identifying multidimensional risk factors compared with traditional statistical approaches. These models highlight complex interrelationships between ergonomic and psychosocial exposures. Future research should incorporate external validation, objective exposure measurements, and standardized ML reporting frameworks to enhance methodological transparency and generalizability.

Colorectal cancer (CRC) has become a significant worldwide health issue among Malaysians. It has become the second most common disease among men and women, with an increased mortality rate in recent years. CRC cases can be reduced with a healthy diet by increasing natural product intake. However, today most of the commercialized natural products for CRC prevention are imported and costly, which makes 80% of the Malaysian population could hardly afford them due to low and middle household income. Therefore, the present study summarizes the list of local tropical natural products that have remarkable medicinal properties effective on CRC, which are easily accessible for Malaysians, ways to consume them at home, and the economic prospects. This narrative review reviews the latest natural products' properties against CRC, excluding the plants examined in previous studies. The keywords utilized to identify the relevant articles were “Malaysia," "Colorectal Cancer," “Natural products," “Anticancer," "Antidiarrheal," "Mucositis," and "Vomit/Nausea" through PubMed, ScienceDirect, and Google Scholar. Conclusion: In conclusion, the locally available natural products have excellent medicinal properties against colorectal cancer with enormous potential medicinal properties in treating CRC and chemotherapy-induced toxicity that Malaysians can use to improve their well-being.

Introduction: Dengue fever (DF) is a prominent vector-borne disease spread by mosquitos of the Aedes genus (mainly Aedes aegypti, and even Aedes albopictus), a tropical regions vector. The purpose of this research was to establish the spatial and temporal distribution patterns of DF cases in the study area between 2010 and 2020. Methods: The correlation between the Kuantan sub-district and dengue haemorrhagic fever (DHF) incidence is examined in this study using spatial analysis. The correlation was calculated using spatial autocorrelation, Moran’s Index (Moran’s I) and Spatial Autocorrelation of Local Indicators (LISA). Moran’s index is a worldwide indicator used to determine whether or not disease transmission has geographical autocorrelation in disease transmission. Results: The results indicated that between 2011 and 2020, the monthly Moran’s I of dengue transmission in Kuantan was estimated to range between -0.685 and 0.338. The lowest reading of Moran’s index was -0.685 in May 2015, whereas the highest reading was 0.338 in May 2019. This reflects the strong spatial autocorrelation of dengue transmission in Kuantan over the last decade. The LISA analysis revealed significant spatial autocorrelations on DF cases in Kuantan for three (3) out of six (6) sub-districts (50%) with a significance level of 2%. This suggests that there are spatial autocorrelations in Kuala Kuantan, Beserah and Penor sub-district that influence the distribution of DHF transmission. Conclusion: The results reveal that the spatial autocorrelation analysis method can be a tool for relevant researchers to understand the pattern of DF transmission study and establish the direction for further study.

Introduction: Anaemia is common during pregnancy and can lead to miscarriage, intrauterine growth retardation, premature labour and antepartum haemorrhage. Anaemia in pregnancy is defined as a haemoglobin (Hb) level of <11 g/dL. Methods: This retrospective review included 407 antenatal mothers diagnosed with anaemia at 36±1 weeks of gestation at all 10 health clinics in Alor Gajah between January and December 2018. Results: According to the district annual returns, 2,407 antenatal mothers (36 weeks of gestation) were registered in the health clinics in Alor Gajah in 2018. Among them, the prevalence of anaemia was 18.6% (n=448). However, there were only 407 cards found. Most participants were Malays (89.4%), aged 20–40 years (93.6%) and married (96.3%). Almost all anaemia cases (96.5%) were mild (Hb level of 9–10.9 g/dL). Approximately 34.4% of the mothers were already anaemic at booking; 77.6% belonged to the B40 income group; and 31.6% had poor pregnancy spacing of <2 years. Iron deficiency anaemia was the most common type of anaemia (51.0%), followed by dilutional anaemia (34.0%), which did not normalise at 36 weeks of gestation. Anaemia was associated with lower educational (P<0.05) and Hb levels at booking (P<0.001). Conclusion Having normal maternal Hb levels in early pregnancy especially at booking is crucial, as it may reduce the possibility of anaemia during pregnancy. Early screening and supplementation of at-risk pregnancies may be applied as a preventive strategy. Suitable methods of iron treatment and investigation need further exploration.

Despite pulmonary cryptococcosis showing good response to antifungal treatment, making accurate diagnosis in a timely manner remains a challenge. Tissue for fungal culture is less sensitive, nonspecific, and time-consuming to allow for prompt diagnosis. We herein report a case of 31-year-old woman with no known medical illness but presented with history of cough and haemoptysis for two months. The chest X-ray and bronchoscopy revealed left lung mass. While tuberculosis showed negative result and no growth observed in the tissue culture, the histopathological examination (HPE) finding was suggestive of fungal infection. The formalin-fixed paraffin-embedded (FFPE) tissue was sent for molecular testing, which revealed Cryptococcus neoformans. This report emphasises on the advantages and limitations of polymerase chain reaction (PCR) as an alternative method to confirm the diagnosis in cases of culture-negative fungal infection.

In 2005, Ministry of Health introduced the Needle Syringe Exchange Program (NSEP) and Methadone Maintenance Therapy (MMT) program as a part of Harm Reduction program to combat HIV infection in Malaysia among people who inject drug (PWIDs). Expenditures were estimated approximately RM10 millions per year to establish and sustain the NSEP and MMT centres. This study examined the impact of MMT program on preventing HIV seroconversion among registered MMT clients that are people who inject drug (PWIDs), and to identify other predictors of HIV seroconversion among this group. This was a retrospective cohort study done in the state of Perak involving a total of 212 randomly selected MMT clients registered between 2008-2017 in 6 clinics. This study looks at data collected from the last ten-year cohort from baseline to follow-up. A questionnaire was used to obtain socio-demographic data, sexual and drugs abuse history. Test results for HIV were obtained from medical records. Cox regression analysis was performed to examine factors associated with seroconversion and Kaplan-Meier analysis to estimate HIV survival time. This study displayed that both Methadone take home supply (HR 10.4, 95% CI: 1.6 – 68.8) and unprotected sexual practice (HR 5.9, 95%CI: 1.1 – 31.5) shown higher risks of HIV seroconversion compared to DOTS and condom practice among MMT clients respectively. Mean survival for HIV seroconversion among MMT clients was 104.44 (95%CI: 101.85 – 107.04) months. This study provides reliable evidence that MMT program markedly reduces incidence of HIV infection among people who inject drug (PWIDs).

Analysis of cell cycle arrest, apoptosis assay and apoptosis protein expressions were determined by flow cytometry. Results: Methanolic extract of A. precatorius leaves showed the lowest IC50 on MDA-MB-231 cells at (26.40±5.40) μg/mL. Flow cytometry analysis revealed that cell arrest occurred at G0/G1 phase and the apoptosis assay showed the occurrence of early apoptosis at 48 h in MDA-MB-231 cells treated with methanolic extract of A. precatorius leaves. Methanolic extract of A. precatorius leaves induced apoptosis by upregulation of Bax, p53 and caspase-3 and downregulation of Bcl-2. Conclusions: Methanolic extract of A. precatorius leaves promotes MDA-MB-231 cell death by inducing cell cycle arrest and apoptosis possibly via the mitochondrial-related pathway.

Objective: To identify the phytochemical compounds from Annona muricata (A. muricata) and to determine their in vitro anti-proliferative activities against breast cancer cells, MCF7 and MDA-MB-231. Methods: A. muricata leaves were successively extracted by soxhlet method using n-hexane, ethyl acetate and methanol, and decocted with water. Each extract was analysed by gas chromatography mass spectrometry (GCMS) and characterized with Wiley and NIST library searches. Anti-proliferative activity of each extract was evaluated on MCF7 and MDA-MB-231 breast cancer cells using MTT assay. Results: The GCMS analysis of different solvent extracts of A. muricata leaves showed presence of different chemical groups of compounds such as steroids, terpenoids, phenolic compounds, sugars, sugars alcohol and others including vitamin E. Ethyl acetate leaves extract exhibited the lowest IC

Objective: This case report aims to discuss the diagnosis of mental retardation as insanity defence in a crime offender. Methods: We report a gentleman who committed murder and rape 9 years ago, and currently being treated at a mental institution. Results: Patient was certified to have mental retardation, and was pleaded on the defence of unsoundness of mind because he had defect of reason at the time of alleged offence. Conclusion: Mental retardation does fulfil the McNaughton’s rule. Unsoundness of mind becomes the insanity defence even for murder under section 84 of the Penal Code.
