Introduction: Polycystic ovarian syndrome (PCOS) is a complex endocrine disorder that significantly affects adolescent girls, particularly those with overweight or obesity. However, data examining the determinants and metabolic profiles of PCOS among adolescents with overweight and obesity remain limited, especially in Malaysia. This protocol describes a case-control study investigating the cardiometabolic, dietary, and psychosocial determinants of PCOS among adolescents with overweight and obesity. Methodology: This study is designed as a case-control study involving adolescent girls aged 13–16 years with a body mass index z-score >+1 standard deviation. Cases are defined as adolescent girls with a confirmed diagnosis of PCOS based on the recommendations of the 2017 International Consortium of Paediatric Endocrinology (ICPE), while controls are those who do not meet the diagnostic criteria for PCOS. A total sample size of 440 participants is required. Participants will be recruited from 22 secondary schools selected from a list of schools in Kuala Lumpur. Data on sociodemographic characteristics, psychosocial health, physical activity, and dietary intake will be collected using structured questionnaires. Blood samples will be obtained and analyzed for diagnostic testing (free testosterone), exclusion tests (thyroid-stimulating hormone, folliclestimulating hormone, luteinizing hormone, estradiol, prolactin, and dehydroepiandrosterone sulfate), and biochemical parameters (liver function tests, lipid profile, hemoglobin A1c, fasting glucose, fasting insulin, and inflammatory markers). Results: The study is expected to generate comprehensive data on the cardiometabolic, dietary, and psychosocial determinants of PCOS among adolescents with overweight and obesity. The findings will inform early screening strategies and targeted interventions aimed at reducing long-term reproductive and cardiometabolic complications. Conclusion This protocol outlines a structured approach to investigating PCOS in adolescence and addresses current gaps in early identification and risk stratification among highrisk populations.

Introduction: Pituitary apoplexy is a rare, life-threatening condition resulting from hemorrhage or infarction of the pituitary gland, most commonly in patients with pre-existing pituitary tumors. It typically presents with a sudden headache, visual disturbance, ophthalmoplegia, and altered mental status. An uncommon but serious complication is ischemic stroke in the middle cerebral artery (MCA) territory, particularly in the absence of direct internal carotid artery (ICA) compression. Case: We report a case of a 36-year-old male who presented with headache, visual impairment, and fever. Initial computed tomography (CT) brain imaging demonstrated a heterogeneous sellar lesion with peripheral calcification measuring 2.4 × 3.2 × 2.7 cm, suggestive of a pituitary mass with possible apoplexy, without evidence of acute cerebral infarction. The patient subsequently developed dysarthria, hemianopia, and reduced consciousness, prompting repeat neuroimaging. Follow-up CT revealed a large hypodense area in the right fronto-parieto-temporal region consistent with ischemic infarction. Magnetic resonance imaging confirmed an acute infarct in the right MCA territory without hemorrhagic transformation. A sellar-suprasellar mass measuring 2.3 × 2.8 × 3.8 cm was identified, consistent with a pituitary macroadenoma with intratumoral hemorrhage compressing the optic chiasm, but without direct right ICA compression. Time-of-flight mineralocorticoid receptor antagonists demonstrated attenuated flow in the right ICA (C2–C7), suggesting intracranial ICA thrombosis and reduced perfusion in the right MCA and its branches. Laboratory evaluation revealed hyperthyroidism and hypocortisolism, with no evidence of coagulopathy. The patient was treated with corticosteroid replacement and carbimazole and referred for neurosurgical management. Conclusion This case highlights a rare association between pituitary apoplexy and MCA stroke, possibly mediated by vasospasm, inflammation, or hypercoagulability. More research is needed to understand this connection and improve treatment strategies.

Introduction: X-linked hypophosphatemia (XLH) is a rare genetic disorder caused by PHEX mutations, characterized by chronic hypophosphatemia and renal phosphate wasting, resulting in skeletal, dental, and extra-skeletal complications. To date, no data from Malaysia are currently available on clinical characteristics or health-related quality of life (HRQoL) in paediatric patients. Methodology: This cross-sectional study evaluated HRQoL among children and adolescents with XLH, using validated PROMIS (PatientReported Outcomes Measurement Information System) instruments, sociodemographic and clinical factors associated with HRQoL. This includes children and adolescents with confirmed XLH followed up at Universiti Malaya Medical Centre (UMMC) between November 2024 and March 2025. Results: Seventeen patients were analyzed (76.5% female and 23.5% male). The mean age at symptom onset was 2.82 ± 2.42 years, with a mean age at diagnosis of 5.21 ± 3.29 years. All patients continued to have musculoskeletal complications, including short stature (76.5%), bowing of legs (76.5%), bone/joint pain (47.1%), muscle pain (47.1%), and dental complications (52.9%). Serum alkaline phosphatase improved significantly (p = 0.011); persistent hypophosphatemia and ongoing musculoskeletal manifestations indicated suboptimal disease control. Elevated parathyroid hormone levels and an increase in urine calciumto-creatinine ratio (p = 0.020) lead to secondary hyperparathyroidism and nephrocalcinosis. Adherence to conventional therapy was poor. Non-adherence was associated with worse pain outcomes (higher pain interference [p = 0.037] and greater pain intensity [p = 0.025]). PROMIS scores revealed severely impaired mobility (mean T-score 31.31 ± 12.17), increased fatigue (mean T-score 54.22 ± 7.60), and high pain interference (mean T-score 63.11 ± 9.50). Larger household size was also strongly associated with higher pain intensity (p = 0.004). Conclusion Malaysian children and adolescents with XLH continue to have significantly poor HRQoL, particularly in mobility, fatigue, and pain. These findings highlight the need for access to targeted therapies, such as burosumab, to improve long-term outcomes and QOL in XLH patients.

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.

Stunting remains a major public health concern in Southeast Asia, and is shaped by a complex interplay of genetic, inflammatory, and nutritional factors. This scoping review sought to map genetic polymorphisms associated with stunting in Southeast Asian children and to identify candidate biomarkers for early diagnosis and biologically targeted interventions. Following the Arksey and O'Malley framework and the PCC (Population, Concept, Context) model, a systematic search was conducted across 7 databases. Eligible studies were peer-reviewed, published in English from 2015–2024, involved children under 18 years of age, and investigated gene variants in relation to stunting. A total of 902 records were screened independently by 3 reviewers using predefined criteria, with consensus procedures to resolve any discrepancies. Eleven studies met the final inclusion criteria. Thematic analysis and protein-protein interaction mapping revealed that 5 key polymorphisms—IGF1R, GHSR, MTRR, CASP1, and CARD17—were significant contributors to growth impairment. IGF1R polymorphisms were associated with a 2.46-fold increase in stunting risk (odds ratio [OR], 2.46; 95% confidence interval [CI], 1.60–3.78), while MTRR< variants yielded an OR of 1.93 (95% CI, 1.22–3.05). Similarly, GHSR and CASP1 polymorphisms were linked to increased odds of stunting (OR, 2.15; 95% CI, 1.38–3.34 and OR, 1.67; 95% CI, 1.10–2.54, respectively). These polymorphisms were consistently associated with disrupted growth hormone signaling, chronic inflammation, and nutrient-sensitive pathways. The biological network underlying stunting in this population points to a converging mechanism of impaired endocrine function and inflammatory dysregulation. However, this review’s scope is limited by underrepresentation of some Southeast Asian nations and exclusion of non-English literature. Early genetic screening for high-risk biomarkers and precision-driven nutritional interventions may offer more effective strategies to reduce the burden of stunting in Southeast Asian children.

Background: The co-occurrence of frailty, sarcopenia, and malnutrition was well studied in inpatient and nursing home settings, which was associated with higher risk of all-cause mortality. Multicentre data in community-dwelling outpatient setting were lacking. We aimed to find the prevalence of frailty, possible sarcopenia and malnutrition, their overlap and the associated factors in community-dwelling older outpatients. Methods: We collected data from community-dwelling outpatients aged ≥60 years in Indonesian geriatric care centres to conduct this cross-sectional study with bivariate and multivariable analyses. Frailty, possible sarcopenia, and malnutrition diagnoses were based on FRAIL scale, Asian Working Group for Sarcopenia 2019 consensus, and Mini Nutritional Assessment Short Form, respectively. Results: The prevalence of frailty, possible sarcopenia, and malnutrition in community-dwelling older outpatients were 13.6%, 45.5%, and 5.3%, respectively. The prevalence of co-occurrence of frailty, possible sarcopenia and malnutrition was 3.3%. It was associated with transient ischemic attack (TIA) and cerebrovascular accident (odds ratio [OR]=5.53, 95% confidence interval [CI] 1.48–20.61), cognitive impairment (OR=3.70, 95% CI 1.21–11.31), and dependent functional capacity (OR=11.62, 95% CI 3.38–39.99). Overlap of three evaluated syndromes was found in 24.1%, 7.2%, and 61.3% of subjects with frailty, possible sarcopenia, and malnutrition, respectively. It was characterized by a substantial proportion of female sex, older adults with low educational attainment, diabetes mellitus, hypertension, cognitive impairment, multimorbidity, and dependent functional status. Conclusion Approximately 1 in 30 community-dwelling older outpatients had overlapping frailty, possible sarcopenia, and malnutrition. The condition is associated with TIA and cerebrovascular accident, cognitive impairment, and dependent functional capacity. Standardized screening in community-dwelling older population is necessary.

Background: Understanding the relationship between muscle mass, muscle strength, and bone density in older adults is crucial for addressing age-related conditions like osteoporosis and sarcopenia. This review aims to evaluate the relationship between muscle mass and muscle strength with bone density in older adults. Methods: This systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, involved a comprehensive search across seven databases from 2014 to April 2024. Included were observational studies in English and Indonesian on adults aged 60 and older. The Appraisal Tool for Cross-Sectional Studies (AXIS) tool assessed the risk of bias, and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) framework evaluated the evidence quality. Study selection was independently reviewed, and consensus was reached through discussion. Results: Ten studies were included. For muscle mass and bone density, five studies showed a significant association, while four did not. For muscle strength and bone density, four of seven studies reported a significant association. However, the evidence quality was low due to inconsistency. Conclusion The relationship between muscle mass, muscle strength, and bone density in older adults shows variability and inconsistent evidence.

Gastroesophageal reflux disease (GERD) is a common digestive disorder that affects millions of people worldwide. Reflux of gastric acid may cause oral acidification that can induce teeth demineralization. Destruction of dental hard tissue by acid reflux necessitates a combine approach involving medical and dental profession. This pilot study aims to assess associationbetween enamel erosion and GERD, and estimate prevalence of enamel erosion among GERD patients. A total of 22 patients (GERD and control) were involved in this case-control study. Dental charting was done using five-point ordinal scales of modified Tooth Wear Evaluation System (TWES 2.0). Cohen’s Kappa Coefficient was used for assessment of intra-rater and inter-rater reliability. Fisher’s Exact Test was used to determine association between enamel erosion and GERD, reflecting prevalence. Out of 11 GERD patients, 63.6% exhibit enamel erosion, whereas only 9.1% ofcontrol patient presented with enamel erosion. Fisher’s Exact Test showed a significant prevalence of enamel erosion in GERD patients (p=0.024).This study showeda clear association between enamelerosion and GERD, and it can be considered as an oral manifestation in patient with GERD. Future study involving large sample size is recommended to show clear statistical evidence ofassociation betweenenamel erosion and GERD.
