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.

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:
Non-diabetic hypoglycemia in older adults warrants
careful evaluation across insulin-mediated and noninsulin-mediated causes. We present a challenging case of
insulin autoimmune syndrome (IAS; Hirata’s syndrome).
Case:
An 85-year-old female presented with severe hypoglycemia (capillary blood glucose [CBG] 1.8 mmol/L) with
reduced consciousness, preceded by 2 months of recurrent
dizziness relieved by food intake. Appetite and weight were
stable. Past medical history included stage 3 chronic kidney
disease and osteoporosis, but no diabetes. Medication
review revealed a recent 2-week course of traditional
supplement, long-term Neurobion®, but no agents with
recognized hypoglycemic potential. Physical examination
showed a moderately built elderly female with a body
mass index of 24.3 kg/m² and no Cushingoid features.
Recurrent hypoglycemia (CBG nadir 1.5 mmol/L) occurred
in both fasting and postprandial states, fulfilling Whipple’s
triad. Baseline investigations showed an estimated
glomerular filtration rate of 42 mL/min/1.73 m², AM
cortisol of 700 mmol/L, and unremarkable liver and thyroid
function tests. During a hypoglycemic episode (CBG 2.3
mmol/L), plasma insulin and C-peptide were inappropriately raised at 203.6 mU/L (reference interval [RI]: 3.0–
25.0) and 33 ng/mL (RI: 0.9–7.1), respectively, confirming
endogenous hyperinsulinemic hypoglycemia. Polyethylene
glycol precipitation showed 21% insulin recovery, raising
suspicion for an autoimmune cause. Elevated insulin
autoantibodies (175 AU/mL; RI <20) confirmed IAS.
Computed tomography of the abdomen and endoscopic
ultrasound excluded a pancreatic neuro-endocrine tumor.
Nutritional management comprising frequent low glycemic
index feeds and uncooked cornstarch was commenced.
Diazoxide 100 mg TDS caused fluid overload and severe
hyponatremia, while hypoglycemia persisted at lower doses, necessitating discontinuation. Subcutaneous octreotide 100 mg QID was required to control hypoglycemia.
Prednisolone 30 mg BD improved glycemic stability. Insulin
autoantibodies titer remained 175 AU/mL at 2 weeks;
reassessment was conducted at 4 weeks with consideration for biologics if persistent.

Conclusion
Endogenous hyperinsulinemic hypoglycemia, after
excluding insulinoma, should raise suspicion for IAS.
Management includes removing triggers, supportive care,
and immunomodulatory therapy in severe cases.

Epigallocatechin-3-gallate (EGCG), a bioactive polyphenol abundant in green tea, has garnered significant attention for its diverse therapeutic applications, ranging from antioxidant and anti-inflammatory effects to potential anticancer properties. Despite its immense promise, the practical utilization of EGCG in therapeutic settings as a medication has been hampered by inherent limitations of this drug, including poor bioavailability, instability, and rapid degradation. This review comprehensively explores the current challenges associated with the application of EGCG and evaluates the potential of nanoparticle-based formulations in addressing these limitations. Nanoparticles, with their unique physicochemical properties, offer a platform for the enhanced stability, bioavailability, and targeted delivery of EGCG. Various nanoparticle strategies, including polymeric nanoparticle, micelle, lipid-based nanocarrier, metal nanoparticle, and silica nanoparticle, are currently employed to enhance EGCG stability and pharmacological activity. This review concludes that the particle sizes of most of these formulated nanocarriers fall within 300 nm and their encapsulation efficiency ranges from 51% to 97%. Notably, the pharmacological activities of EGCG-loaded nanoparticles, such as antioxidative, anti-inflammatory, anticancer, and antimicrobial effects, are significantly enhanced compared to those of free EGCG. By critically analyzing the existing literature and highlighting recent advancements, this article provides valuable insights into the promising prospects of nanoparticle-mediated EGCG formulations, paving the way for the development of more effective and clinically viable therapeutic strategies.

Epigallocatechin-3-gallate (EGCG), a prominent plant-based catechin predominantly derived from Camellia sinensis and widely available on the market as a health supplement, has garnered significant attention for its potential therapeutic benefits, particularly in the context of type 2 diabetes mellitus (T2DM). This review explores the multifaceted role of EGCG in addressing the "ominous octet"-the 8 core pathophysiological defects associated with T2DM. The literature search was carried out using key terms "EGCG" OR "epigallocatechin-3-gallate" OR "epigallocatechin gallate" AND "diabetes" OR "insulin resistance" OR "hyperglycemia" in the PubMed and Scopus databases. The search was constrained to articles published between January 2018 and April 2024, focusing on the document type. Full-text articles published in English and relevant to EGCG that featured a single active ingredient, included clearly explained diabetes relief mechanism, and included ominous octet aspects were included in the final review. The outcomes of the included studies were reviewed and categorized based on 8 core pathophysiological defects, collectively referred to as the ominous octet in T2DM. This review concludes that EGCG is a potent hypoglycemic agent that has beneficial effects against the ominous octet in addition to its pharmacological activities in modulating gut microbiota dysbiosis, carbohydrate digestion and metabolism, glucose transporter-mediated intestinal glucose-uptake, endothelial dysfunction, and renal damage that are significantly associated with pathogenesis of T2DM. This extensive scientific evidence suggests that EGCG may offer a novel approach to traditional antidiabetic therapies, potentially improving glycemic control and mitigating complications associated with T2DM. The inhibitory effects of EGCG on sodium-glucose transport proteins and their role in reducing renal glucose reabsorption remain unexplored, highlighting a significant research gap. Future research should also aim to broaden the scope by investigating the "egregious eleven," which comprise a more comprehensive range of diabetic pathophysiological features. This review underscores the therapeutic promise of EGCG for managing T2DM and encourages ongoing research to fully elucidate its clinical applications.

People with type 2 diabetes mellitus have increased risk of chronic kidney disease and atherosclerotic cardiovascular disease. Improved care delivery and implementation of guideline-directed medical therapy have contributed to the declining incidence of atherosclerotic cardiovascular disease in high-income countries. By contrast, the global incidence of chronic kidney disease and associated mortality is either plateaued or increased, leading to escalating direct and indirect medical costs. Given limited resources, better risk stratification approaches to identify people at risk of rapid progression to end-stage kidney disease can reduce therapeutic inertia, facilitate timely interventions and identify the need for early nephrologist referral. Among people with chronic kidney disease G3a and beyond, the kidney failure risk equations (KFRE) have been externally validated and outperformed other risk prediction models. The KFRE can also guide the timing of preparation for kidney replacement therapy with improved healthcare resources planning and may prevent multiple complications and premature mortality among people with chronic kidney disease with and without type 2 diabetes mellitus. The present review summarizes the evidence of KFRE to date and call for future research to validate and evaluate its impact on cardiovascular and mortality outcomes, as well as healthcare resource utilization in multiethnic populations and different healthcare settings.

Objectives:
The aim of these Clinical Practice Guidelines is to provide evidence-based recommendations to assist healthcare providers in the screening, diagnosis and management of patients with postmenopausal osteoporosis (OP).
Methods:
A list of key clinical questions on the assessment, diagnosis and treatment of OP was formulated. A literature search using the PubMed, Medline, Cochrane Databases of Systematic Reviews, and OVID electronic databases identified all relevant articles on OP based on the key clinical questions, from 2014 onwards, to update from the 2015 edition. The articles were graded using the SIGN50 format. For each statement, studies with the highest level of evidence were used to frame the recommendation.
Results:
This article summarizes the diagnostic and treatment pathways for postmenopausal OP. Risk stratification of patients with OP encompasses clinical risk factors, bone mineral density measurements and FRAX risk estimates. Non-pharmacological measures including adequate calcium and vitamin D, regular exercise and falls prevention are recommended. Pharmacological measures depend on patients’ fracture risk status. Very high-risk individuals are recommended for treatment with an anabolic agent, if available, followed by an anti-resorptive agent. Alternatively, parenteral anti-resorptive agents can be used. High-risk individuals should be treated with anti-resorptive agents. In low-risk individuals, menopausal hormone replacement or selective estrogen receptor modulators can be used, if indicated. Patients should be assessed regularly to monitor treatment response and treatment adjusted, as appropriate.
Conclusions
The pathways for the management of postmenopausal OP in Malaysia have been updated. Incorporation of fracture risk stratification can guide appropriate treatment.
