Introduction: Diabetic ketoacidosis (DKA) is a life-threatening complication associated with significant morbidity and healthcare burden. Despite advances in diabetes care, recurrent DKA remains common, often reflecting gaps in treatment adherence and patient education. Identifying predictors of recurrence is crucial for risk stratification and targeted intervention. Methodology: We conducted a retrospective observational study of all adult DKA admissions to a tertiary centre between 2001 and 2025. Electronic medical records were reviewed for demographic data, biochemical parameters, precipitating factors, and clinical outcomes. DKA was defined using standard biochemical criteria. Recurrent DKA was defined as ≥2 admissions during the study period. Factors associated with recurrent DKA admissions were analyzed. Patients under the age of 18 years and those with missing vital information were excluded. Results: A total of 667 DKA admissions, comprising 566 patients, were identified, of which 101 admissions (15.1%) were recurrent, involving 65 patients. Among recurrent DKA episodes, the most common precipitating factors were infection (64.4%) and insulin omission (62.4%). After multivariate analyses, patients with type 1 diabetes mellitus (T1DM) were more likely to develop recurrent DKA compared to those with type 2 diabetes mellitus (aOR 4.16; 95% confidence interval [CI] 2.58–6.70; p <0.001). Insulin omission was strongly associated with recurrent DKA (aOR 2.29; 95% CI 1.46–3.60; p <0.001). In contrast, baseline glycated hemoglobin and chronic kidney disease were not significantly associated with recurrence. Diabetic counseling during the first DKA admission did not reduce recurrent DKA. There were no significant differences in mortality (3.9% vs 6.2%, p = 0.524) or critical care admission rates (40.6% vs 38.7%, p = 0.718) between recurrent and first DKA episodes. Conclusion Recurrent DKA accounts for a substantial proportion of DKA admissions and is strongly associated with insulin omission and T1DM. Our findings suggest that recurrent DKA is driven predominantly by behavioral and adherencerelated factors, indicating the need for multidisciplinary interventions beyond standard inpatient counseling.
Diabetic Ketoacidosis ; Retrospective Studies

Introduction: The rising incidence of diabetic ketoacidosis (DKA) in type 2 diabetes mellitus (T2DM) represents a paradigm shift from its traditional recognition as a hallmark complication of type 1 diabetes mellitus (T1DM). However, contemporary data comparing clinical presentation, precipitating factors, and outcomes between these two populations remain limited. Methodology: In this retrospective observational study, all adult DKA admissions with T1DM or T2DM at a tertiary centre between 2001 and 2025 were studied. DKA was defined according to standard biochemical criteria. Electronic medical records were reviewed to extract demographic data, biochemical parameters, precipitating factors, management details, and clinical outcomes of all adult DKA admission in T1DM and T2DM. Patients aged <18 years or those with incomplete data were excluded. Results: A total of 601 DKA episodes were analyzed, comprising 130 (21.6%) in patients with T1DM and 471 (78.4%) in those with T2DM. Mean age was 26.9 ± 0.71 years for T1DM and 52.1 ± 0.7 years for T2DM. Gender distribution was balanced (male 48.3%, female 51.7%). Mean hemoglobin A1c (HbA1c) was 11.3 ± 0.3% in T1DM and 12.1 ± 0.2% in T2DM. Infection was the most common precipitating factor overall (69.0%), occurring more frequently in T2DM than in T1DM (74.7% vs. 56.2%), followed by medication non-adherence (62.4% vs. 43.8%). Significant differences were observed between groups in admission pH, bicarbonate (both p <0.001), blood ketones (p = 0.028), and HbA1c (p = 0.010), whereas anion gap (p = 0.056) and blood glucose levels (p = 0.755) did not differ significantly. Clinical outcomes were comparable with respect to intensive care unit (ICU) admission rates (40.0% in T1DM vs. 39.0% in T2DM, p = 0.779) and median resolution time (p = 0.462). However, the median length of hospital stay was significantly longer in T2DM (8.2 ± 0.32 vs. 5.4 ± 0.4 days; p <0.001). Overall mortality was 6.0%, with substantially higher mortality in T2DM compared to T1DM (7.4% vs. 0.8%, p = 0.013). Conclusion In this large regional series of adult DKA, most episodes occurred in T2DM. Despite similar ICU admission rates and time to resolution, T2DM was associated with more frequent infection-related precipitants, longer hospital stays, and higher mortality, underscoring the need for targeted preventive strategies in this population.

Introduction: Diabetic ketoacidosis (DKA) in pregnancy is an uncommon yet life-threatening emergency, with disproportionate risks to both mother and fetus. Pregnancy-specific physiological changes predispose patients to rapid metabolic decompensation, often with atypical presentations. Despite this, local data remain limited. We describe the clinical profile, precipitating factors, and outcomes of DKA in pregnancy in a tertiary centre, with emphasis on potentially preventable triggers. Cases: Nine pregnant patients with DKA were identified from a retrospective review of all cases admitted for DKA from 2002 to 2025. Mean age was 31.67 ± 5.20 years; all were Malay. The majority had type 2 diabetes mellitus (55.6%), followed by type 1 diabetes (33.3%) and latent autoimmune diabetes in adults (11.1%). The mean period of amenorrhea was 19.67 ± 12.62 weeks. Infection was the leading precipitant (44.4%), with additional triggers including insulin omission (22.2%), hyperemesis gravidarum, preterm labor, steroid exposure, and perioperative fasting. Most diagnoses were made in the emergency department (55.6%). Biochemical parameters reflected significant severity (mean bicarbonate 7.89 ± 2.98 mmol/L; anion gap 25.00 ± 5.81), with 88.9% classified as severe DKA. Intensive Care Unit (ICU) care was required in 77.8% of cases. The majority (77.8%) were admitted to the ICU unit, with a median time to resolution of 13.00 ± 12.00 hours (interquartile range [IQR]), and the median hospital length of stay was 7.00 ± 5.00 days (IQR). Complications during treatment included hypokalemia (33.3%), acute kidney injury (22.2%), and hypoglycemia (11.1%). Rebound DKA occurred in one-third of patients. All patients were discharged clinically stable. Outcome data demonstrated pregnancy loss in three cases and one preterm birth. Conclusion DKA in pregnancy remains a severe and resource-intensive condition. This series highlights missed opportunities in prevention, with modifiable precipitants such as infection and insulin omission commonly identified. The high severity at presentation suggests delays in recognition. Early detection, optimized metabolic care, and targeted preventive strategies are crucial to improving maternal and fetal outcomes.

Introduction: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) is an uncommon X-linked genetic condition marked by euvolemic hyponatremia, which arises from a gain-of-function mutation in the arginine vasopressin receptor type 2 (AVPR2) gene. In contrast to the classic syndrome of inappropriate antidiuretic hormone secretion (SIADH), NSIAD is characterized by urine that is inappropriately concentrated even when arginine vasopressin (AVP) levels are low or undetectable. Failure to recognize NSIAD may result in recurrent hyponatremia and neurological morbidity. Case: A 2-year-old male was referred to us after recurrent vomiting and subsequently developed generalized tonicclonic seizures due to hyponatremia (with a sodium level of 115 mmol/L). He needed sodium replacement through an intravenous drip of 3% saline and was stabilized with oral sodium chloride 20%. Urine osmolality was elevated, serum osmolality remained normal, and copeptin levels were low. He was discharged after a 10-day hospital stay. During follow-up, hyponatremia recurred despite his typical fluid intake of 1,200 mL/day. He was instructed to limit his fluid intake to 600–700 mL, which successfully normalized his serum sodium levels. Serum levels of adrenocorticotropic hormone, the aldosterone-to-renin ratio, thyroid function tests, and serum cortisol were all within normal ranges. Plasma AVP was unusually low (4.0 pmol/L). Whole exome sequencing (WES) confirmed a likely pathogenic hemizygous variant in AVPR2 gene located on chromosome Xq28, which was inherited from his mother. He is the only child, born from a non-consanguineous marriage, with no other significant family medical history. Conclusion Nephrogenic syndrome of inappropriate antidiuresis (NSIAD), is an uncommon, yet clinically significant condition. This case highlights the importance of considering a broad range of differential diagnoses when a patient presents with hyponatremic seizure. Furthermore, obtaining a detailed family history is essential to identify potential hereditary factors that could contribute to the condition and for genetic counseling.

Objective: Bariatric surgery effectively treats non-alcoholic fatty liver disease (NAFLD). The glutamate-serine-glycine (GSG) index has emerged as a non-invasive diagnostic marker for NAFLD, but its ability to monitor treatment response remains unclear. This study investigates the GSG index's ability to monitor NAFLD's response to bariatric surgery. Methodology: Ten NAFLD participants were studied at baseline and 6 months post-bariatric surgery. Blood samples were collected for serum biomarkers and metabolomic profiling. Hepatic steatosis [proton density fat fraction (PDFF)] and fibroinflammation (cT1) were quantified with multiparametric magnetic resonance imaging (mpMRI), and hepatic stiffness with magnetic resonance elastography (MRE). Amino acids and acylcarnitines were measured with mass spectrometry. Statistical analyses included paired Student’s t-test, Wilcoxon-signed rank test, and Pearson’s correlation. Results: Eight participants provided complete data. At baseline, all had hepatic steatosis (BMI 39.3 ± 5.6 kg/m2, PDFF ≥ 5%). Post-surgery reductions in PDFF (from 12.4 ± 6.7% to 6.2 ± 2.8%, p = 0.013) and cT1 (from 823.3 ± 85.4ms to 757.5 ± 41.6ms, p = 0.039) were significant, along with the GSG index (from 0.272 ± 0.03 to 0.157 ± 0.05, p = 0.001). Conclusion The GSG index can potentially be developed as a marker for monitoring the response of patients with NAFLD to bariatric surgery.

RENAL CELL CARCINOMA (RCC) IN YOUNG ADULTS: A CASE REPORT AND LITERATURE REVIEW Pediatric renal cell carcinoma (RCC) is a rare disease entity and found to show significant differences from adult RCC in terms of epidemiological and histological subtypes. Treatment strategies for paediatric RCC were mainly adopted from adult RCC as there’s no internationally recognized standard treatment guideline to date. Data on clinical outcomes are scarce. We hereby report a case of a 14-year-old female diagnosed with advanced clear cell RCC treated with pazopanib with overall survival of 10 months. There are several case reports and case series supporting the use of anti-VEGF in adolescent RCC though not in clear cell RCC. None has incorporated immune checkpoint inhibitors in adolescent RCC. Safety and efficacy in dosing strategies of anti-VEGF in adolescents is another challenge. As cancer care advances, large scale genetic data analysis leads to the emergence of precision and personalized medicine, but its utilisation in pediatric RCC is yet to be addressed.

Objectives: To evaluate study designs and citation counts of original research published in the Medical Journal of Malaysia (MJM). Methods: The bibliographic data of the MJM for the period 1980-2016 were retrieved from PubMed and analysed using Endnote bibliographic software. Study designs of original journal articles were analysed according to whether the articles were diagnostic study, prognostic study or clinical trial (collectively known as “evidence papers”). The citation counts of the original articles and case reports for the period 2012-2016 were compared in a sub-study using a case-control design. Results: A total of 3952 MJM journal items were retrieved from PubMed for the period 1980-2016; of these, 58.9% were original articles and 29.5% were case reports. Among the original articles, 14.6% were “evidence papers”; 2.3% were diagnostic studies, 7.7% were prognostic studies, 4.6% were clinical trials. In the study period 2012-2016, “other types of original articles” had statistically significantly more citations than case reports. However, there is no difference between “evidence papers” and case reports. Conclusion Our analysis shows the distribution of the types of articles appearing in the MJM for the period of study and serves as a reference for improving citations counts in the local context.
