INTRODUCTION: In the clinical setting, erectile dysfunction (ED) is a significant issue that should not be neglected, as it can adversely impact the quality of life of patients and their partners, especially among overweight and obese populations. This study aims to determine the prevalence of ED and its associated factors among non-diabetic, overweight, and obese patients who attend a government health clinic in Kuantan, Pahang, Malaysia. MATERIALS AND METHODS: A six-month cross-sectional study was conducted from February 2024 to August 2024 at twelve health clinics in Kuantan, Pahang. The selected respondents were married men over 18 years old, and those with diabetes mellitus, cardiovascular disease, psychiatric illness, or illiteracy were excluded. Data were collected using the validated Malay version of the International Index of Erectile Function (IIEF-5). ED was defined as an IIEF-5 score of less than 22. Descriptive analysis and simple and multiple logistic regression were performed using SPSS. RESULTS: All 221 eligible patients in the study responded (100% response rate). The prevalence of ED was 66.1% (n=146). Multiple logistic regression showed that ED was significantly associated with dyslipidemia [AOR (95% CI): 2.42 (1.06–5.52); p-value=0.036], anxiety [AOR (95% CI): 3.99 (1.44–11.01); p-value=0.008] and older age [AOR (95% CI): 1.07 (1.02–1.12); p-value=0.009]. CONCLUSION: The study revealed a high prevalence of ED among non-diabetic overweight and obese patients, potentially linked to increasing age, dyslipidemia, and anxiety. Increasing awareness among the public and healthcare providers could improve detection rates in primary care.

Voltage-gated sodium channels (VGSCs) play pivotal roles in cancer progression and have emerged as promising therapeutic targets and biomarkers. VGSCs comprise multiple subtypes with distinct tissue distributions, influencing tumour characteristics in different ways. Among these, the tetrodotoxin-sensitive α-subunits and the β1 subunit, commonly found in breast cancer, have been implicated in metastasis and tumour aggressiveness. The NaV1.5 channel and its neonatal variant (nNaV1.5) are overexpressed in aggressive cancers such as breast, prostate, colorectal, and lung cancers, thereby enhancing their invasive capacity. nNaV1.5 is particularly significant due to its tumour-specific expression and strong association with poor prognosis, especially in breast cancer, where it regulates cell proliferation, invasion, and tumour microenvironment remodelling. This review highlights nNaV1.5 as a critical ion channel that drives metastasis through ion regulation, extracellular acidification, and cytoskeletal remodelling. We further evaluate current therapeutic strategies, including siRNA, monoclonal antibodies, and small-molecule inhibitors, while addressing translational challenges such as tumour heterogeneity, drug delivery limitations, and off-target cardiotoxicity due to its similarity with the adult isoform. In addition, we explore the potential of nNaV1.5 as a biomarker subject to epigenetic regulations by factors including RE1-silencing transcription factor (REST) and histone deacetylase 2 (HDAC2), which may facilitate patient stratification and treatment optimization. By integrating mechanistic insights, therapeutic opportunities, and translational challenges, this review goes beyond descriptive summaries to provide a framework for advancing nNaV1.5 research from preclinical studies toward clinical application in cancer therapy.

Introduction: Sleep quality has become a public health concern due to serious impacts on individual’s health outcomes. Thus, this cross-sectional study aimed to determine the sleep quality and its associated factors among adults living in the province of Terengganu, Malaysia. Materials and Methods: Socio-demographic information was self-reported whilst anthropometric measurements were measured by trained researchers. Sleep quality was assessed using the validated Pittsburgh Sleep Quality Index (PSQI) whilst eating behavior was measured using the Dutch Eating Behavior Questionnaire (DEBQ). Descriptive statistics and multivariable linear regression models were employed using IBM SPSS version 25.0. Results: A total of 580 participants were enrolled (mean age = 29.1 ± 10.0 years; 51.2% female), of which 74.7% (n = 433) had poor sleep quality (PSQI global score > 5) with a total sleep duration per night of 6.2 ± 1.6 hours. Gender (p-value=0.044), educational level (p-value=0.001), emotional level (p-value=0.005) and external eating (p-value=0.026) were significantly associated with poorer sleep quality. Conclusion: This study underscored the high prevalence of poor sleep quality among adults living in Terengganu, Malaysia. The findings could serve as a basis for developing sleep education strategies that are tailored to improve sleep quality among adults.

Introduction: Food security, defined as consistent access to sufficient, safe, and nutritious food, remains a significant challenge in Malaysia, especially among lowincome households. This study examined associations between food expenditure, food consumption, food adequacy, and food security among lower-ranking prison officers in the B40 income group. Methods: Multistage sampling was used to select study locations and prisons in Malaysia. Purposive sampling was used to select 420 officers, who completed a self-administered, validated questionnaire. Data were analysed descriptively and through multiple linear regression to identify key predictors of food security. Results: All respondents (100%) had acceptable Food Consumption Scores (FCS), with 97.1% showing high food adequacy. However, the vast majority (89.5%) were classified as at risk of food insecurity. Food spending was predominantly directed towards staple cereals and animal proteins, such as chicken and meat, while expenditure on fruits, vegetables, and dairy products was much lower. Food expenditure was strongly linked to food insecurity (β =-0.588, p<0.001). Similarly, food consumption score (β =-0.087, p=0.038) and food adequacy (β =-0.127, p=0.003) were both negatively associated with food insecurity. Conclusion: Although Malaysian prison officers generally had adequate diets, a substantial proportion of households remained food insecure, particularly in terms of dietary diversity and micronutrient intake. Household food expenditure, consumption scores, and food adequacy were all linked to lower food insecurity.

Introduction: Insulin deintensification is an emerging strategy to reduce hypoglycemia and treatment burden in patients on multiple daily injection (MDI ≥3), with potential to improve adherence and glycemic control. However, evidence in poorly controlled type 2 diabetes mellitus (T2DM) remains limited. This study evaluated its effectiveness and identified factors associated with achieving adequate glycemic control following deintensification among patients with poorly controlled T2DM attending Malaysian primary care. Methodology: A retrospective cohort study was conducted among 107 T2DM patients with hemoglobin A1c (HbA1c) >9%, attending Enhanced Diabetic Clinic at Cheras Health Clinic between 2021 and 2025. All patients on basal-bolus insulin (BBI) underwent deintensification. Multivariate logistic regression was performed to identify factors associated with achieving adequate glycemic control (HbA1c <7.5%). Changes in HbA1c following deintensification were assessed using paired t-tests. Results: Overall, 50.5% of patients achieved adequate glycemic control. Hypoglycemia events (AOR 9.5, 95% confidence interval [CI] 1.6–58.3; p = 0.015), MDI (AOR 9.6, 95% CI 1.4–67.1; p = 0.023) and Diabetes Medication Therapy Adherence Clinic (DMTAC) visits (AOR 1.1, 95% CI 1.0– 1.2; p = 0.039) were significantly associated with achieving HbA1c <7.5%. Conversely, patients transitioned from BBI to premixed regimens were less likely to achieve HbA1c <7.5% (AOR 0.22, 95% CI 0.05–0.93, p = 0.039). All insulin deintensification strategies were associated with significant HbA1c improvements with transitioned from BBI to premixed human insulin (mean difference -2.54%, 95% CI 1.77–3.31, p <0.001, Cohen’s d = 1.09), BBI to premixed analogue insulin (mean difference -3.38%, 95% CI 2.26– 4.49, p <0.001, Cohen’s d = 1.62), BBI to basal insulin (mean difference -3.67%, 95% CI 1.79–5.54, p = 0.004, Cohen’s d = 2.05). Conclusion Insulin deintensification is an effective strategy for improving glycemic control in poorly controlled T2DM. These findings highlight the importance of deintensification with careful consideration of hypoglycemia, MDI-related treatment burden, and patient engagement through regular DMTAC visits, which are integral to achieving optimal outcomes and support a personalized approach to diabetes management in primary care.

Introduction: Gestational diabetes mellitus (GDM) is a common pregnancy complication associated with adverse maternal and neonatal outcomes, including hypertensive disorders, caesarean delivery, macrosomia, and increased lifetime risk of type 2 diabetes. Despite its clinical importance, considerable international variation exists in GDM screening and diagnostic criteria. Multiple frameworks are currently used, including those from the World Health Organization (WHO), International Association of Diabetes and Pregnancy Study Groups, Carpenter and Coustan, and the National Diabetes Data Group. Differences in glucose thresholds, testing protocols (one-step versus two-step), and universal versus risk-based screening contribute to heterogeneity in reported prevalence and healthcare burden. In multi-ethnic, middle-income settings such as Malaysia, identifying an evidence-informed and contextappropriate diagnostic approach is critical. Methodology: This scoping review follows the Joanna Briggs Institute methodology and will be reported in accordance with the PRISMA Extension for Scoping Reviews (PRISMA-ScR). PubMed, Scopus, and ScienceDirect will be searched for English-language studies, reviews, guidelines, and consensus statements reporting GDM diagnostic criteria. Two reviewers will independently screen and select studies. Results: Data will be charted on country, study type, diagnostic criteria, gestational age at screening, and reported challenges. Findings will be synthesized descriptively and presented in tables and figures. No formal risk-of-bias assessment will be conducted. Conclusion This review will provide a comprehensive overview of global diagnostic practices, highlight variations and gaps, and support evidence-based selection of a suitable GDM screening and diagnostic strategy for Malaysia.

Introduction: Bullous pemphigoid (BP) is the most common autoimmune blistering disease. Drug-induced BP has been increasingly reported, with dipeptidyl peptidase-4 (DPP-4) inhibitors, particularly vildagliptin, emerging as a notable cause. The pathogenesis is thought to involve the disruption of immune tolerance and epitope spreading, leading to a broader autoimmune response against basement membrane antigens beyond the classic NC16A domain of BP180. This case series highlights the variable clinical spectrum and therapeutic challenges in vildagliptin-induced BP. Case: A 74-year-old male with type 2 diabetes mellitus (T2DM), hypertension, dyslipidemia, and a history of stroke presented with a 2-month history of recurrent, pruritic, tense bullae. He had been on vildagliptin for 36 months. Histopathology confirmed subepidermal blistering, and direct immunofluorescence demonstrated linear IgG/C3 deposition at the dermo-epidermal junction, with positive anti-BP180 antibodies, diagnosing BP. Discontinuation of vildagliptin and initiation of systemic corticosteroids resulted in significant clinical improvement, allowing a rapid prednisolone taper to 5 mg daily without new bullae formation. A 62-year-old female with T2DM and dyslipidemia presented with bullous eruptions 3 months after initiating vildagliptin. Skin biopsy confirmed BP, revealing subepidermal blistering with eosinophils and linear C3/IgG deposition at the basement membrane zone. Vildagliptin was discontinued. Despite initial management with systemic corticosteroids, the disease course was refractory. The patient experienced a flare upon steroid taper and had persistent blistering on prednisolone 20 mg daily, necessitating the addition of azathioprine as a steroidsparing agent. Conclusion This case series illustrates the variable clinical course of vildagliptin-induced BP in which the therapeutic trajectories diverged significantly. Recognition of BP as a potential adverse effect of DPP-4 inhibitors is critical, and management should be individualized.

Introduction: Hypertension is common in obesity and increases cardiovascular risk. Bariatric surgery improves metabolic health, but subgroup differences in blood pressure response remain unclear. This study examined 1-year changes in systolic blood pressure (SBP) and diastolic blood pressure (DBP) after bariatric surgery across sex, age group, and diabetes status. Methodology: This study included 32 obese adults undergoing bariatric surgery, with blood pressure measured at baseline, 6 and 12 months. Generalized estimating equation models were used to evaluate changes in SBP and DBP over time, adjusting for age, sex, surgery type, diabetes category, baseline body mass index, antihypertensive medication use, and baseline blood pressure. Interaction terms were tested to assess differences in blood pressure trajectories across subgroups. Results: Participants were predominantly female (67.4%), with a mean age of 36.9 ± 6.2 years and a mean body mass index of 40.7 ± 8.8 kg/m². Hypertension and diabetes were present in 40.6 and 31.3% of participants, respectively. There was a significant time effect for both SBP (p <0.001) and DBP (p = 0.004). At 12 months post-surgery, mean SBP decreased by 15 mmHg and DBP by 7.9 mmHg compared with baseline (both p <0.001). No significant interactions were observed between time and sex, diabetes category, or age category, indicating that blood pressure improvements were comparable across subgroups. Conclusion Bariatric surgery was associated with clinically meaningful reductions in both SBP and DBP, with similar improvement patterns observed across demographic and metabolic subgroups. These findings support the effectiveness of bariatric surgery as a strategy for blood pressure reduction and cardiovascular risk management in patients with obesity.

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: Skeletal disease in transfusion-dependent thalassemia is commonly attributed to reduced bone mineral density and managed with anti-resorptive therapy. However, chronic iron overload can induce progressive endocrine siderosis, disrupting anabolic pathways essential for bone homeostasis. This mechanism remains under-recognized and may underlie treatment failure in severe cases. Case: We describe a 34-year-old female with transfusiondependent HbE β-thalassemia, post-splenectomy, receiving regular transfusions and iron chelation, who sustained multiple pathological fractures following a trivial fall, including bilateral supracondylar femur fractures and a distal radius fracture. She had severe systemic iron overload (ferritin 2,621 ng/mL) complicated by hepatic cirrhosis, insulin-dependent diabetes, and hypogonadotropic hypogonadism. Bone mineral density assessment demonstrated severe osteoporosis (hip T-score −5.4) despite prolonged bisphosphonate therapy, with prior vertebral compression fracture. Endocrine evaluation revealed multiaxis dysfunction, including gonadal failure and probable growth hormone deficiency, consistent with pituitary and peripheral endocrine siderosis. Conclusion This case demonstrates that skeletal fragility in transfusiondependent thalassemia reflects an endocrine-driven failure of bone formation rather than isolated loss of bone mineral density. Iron overload–induced endocrine siderosis impairs osteoblast function and suppresses anabolic signaling, leading to profound skeletal vulnerability. The progression of osteoporosis despite anti-resorptive therapy highlights the limitation of conventional approaches and supports reframing thalassemia-associated bone disease as an endocrine disorder. Severe osteoporosis should prompt systematic endocrine evaluation, with early hormonal replacement and consideration of anabolic therapy to prevent catastrophic fractures and long-term disability.
