    BACKGROUND: The effect of modest alcohol intake on prevalence of significant hepatic steatosis and severity of liver disease in patients with type 2 diabetes mellitus (T2DM) is unclear.

    METHODS: This is a cross-sectional study on T2DM patients. Modest alcohol intake was defined as alcohol intake ≤ 21 units/week in men and ≤ 14 units/week in women. Significant hepatic steatosis was diagnosed on the basis of controlled attenuation parameter > 263 dB/m, while advanced fibrosis was diagnosed on the basis of liver stiffness measurement ≥ 9.6 kPa using M probe or ≥ 9.3 kPa using XL probe. Patients with liver stiffness measurement ≥ 8.0 kPa were offered liver biopsy.

    RESULTS: Five hundred fifty-seven patients underwent transient elastography, and 71 patients underwent liver biopsy. The prevalence of modest drinking was 16.5%. Modest drinking was equally prevalent among ethnic Indians and Chinese at 22.9% and 23.3%, respectively, but uncommon among ethnic Malays at 1.7%. Modest drinkers were more likely to be male, smoked, and had significantly lower glycated hemoglobin, total cholesterol, low-density lipoprotein cholesterol, alkaline phosphatase, and platelet count. There was no significant difference in the prevalence of significant hepatic steatosis or advanced fibrosis based on transient elastography and steatohepatitis or advanced fibrosis between modest drinkers and nondrinkers. The prevalence of significant hepatic steatosis was higher among ethnic Malays and Indians compared with ethnic Chinese, but the Chinese did not have a lower prevalence of more severe liver disease.

    CONCLUSION: Modest alcohol intake is not associated with higher prevalence of significant hepatic steatosis or more severe liver disease among patients with T2DM.

    Aim: This study investigated the incidence of sulfonylurea-induced hypoglycemia and its predictors in Type 2 diabetes (T2D) patients. Patients & methods: In this prospective, observational study, T2D patients on maximal sulfonylurea-metformin therapy >1 year were enrolled. Hypoglycemia was defined as having symptoms or a blood glucose level <3.9 mmol/l. Results: Of the 401 patients, 120 (29.9%) developed sulfonylurea-induced hypoglycemia during the 12-month follow-up. The ABCC8 rs757110, KCNJ11 rs5219, CDKAL1 rs7756992 and KCNQ1 rs2237892 gene polymorphisms were not associated with sulfonylurea-induced hypoglycemia (p > 0.05). Prior history of hypoglycemia admission (odds ratio = 16.44; 95% CI: 1.74-154.33, p = 0.014) independently predicted its risk. Conclusion: Sulfonylurea-treated T2D patients who experienced severe hypoglycemia are at increased risk of future hypoglycemia episodes.

    Metabolic dysfunction-associated steatotic liver disease (MASLD) is the latest term for steatotic liver disease associated with metabolic syndrome. MASLD is the most common cause of chronic liver disease and is the leading cause of liver-related morbidity and mortality. It is important that all stakeholders be involved in tackling the public health threat of obesity and obesity-related diseases, including MASLD. A simple and clear assessment and referral pathway using non-invasive tests is essential to ensure that patients with severe MASLD are identified and referred to specialist care, while patients with less severe disease remain in primary care, where they are best managed. While lifestyle intervention is the cornerstone of the management of patients with MASLD, cardiovascular disease risk must be properly assessed and managed because cardiovascular disease is the leading cause of mortality. No pharmacological agent has been approved for the treatment of MASLD, but novel anti-hyperglycemic drugs appear to have benefit. Medications used for the treatment of diabetes and other metabolic conditions may need to be adjusted as liver disease progresses to cirrhosis, especially decompensated cirrhosis. Based on non-invasive tests, the concepts of compensated advanced chronic liver disease and clinically significant portal hypertension provide a practical approach to stratifying patients according to the risk of liver-related complications and can help manage such patients. Finally, prevention and management of sarcopenia should be considered in the management of patients with MASLD.

    Lactation ketoacidosis is a rare yet severe metabolic emergency that has been reported in breastfeeding mothers. Reduced carbohydrate intake during breastfeeding has been reported as a common trigger for ketoacidosis. We report the case of a 31-year-old mother without diabetes who presented with life-threatening lactation ketoacidosis after following a ketogenic diet while exclusively breastfeeding her newborn baby. She was managed in the intensive care unit with dextrose and insulin infusion to reverse ketoacidosis. With prompt treatment, the patient's ketoacidosis resolved within 24 hours, and she was discharged well 3 days later. We further discuss the underlying increased metabolic demand in lactating women that puts them at risk of ketoacidosis, underlining the importance of early recognition of lactation ketoacidosis and nutritional education for lactating women.

    OBJECTIVE: This study aims to report the demographic features of patients with acromegaly, the disease burden, and the corresponding treatment patterns and outcomes in Malaysia.

    METHODOLOGY: This is a retrospective study that included patients from the Malaysian Acromegaly registry who were diagnosed with acromegaly from 1970 onwards. Data collected included patient demographics, clinical manifestations of acromegaly, biochemical results and imaging findings. Information regarding treatment modalities and their outcomes was also obtained.

    RESULTS: Registry data was collected from 2013 to 2016 and included 140 patients with acromegaly from 12 participating hospitals. Median disease duration was 5.5 years (range 1.0 - 41.0 years). Most patients had macroadenoma (67%), while 15% were diagnosed with microadenoma. Hypertension (49.3%), diabetes (37.1%) and hypopituitarism (27.9%) were the most common co-morbidities for patients with acromegaly. Majority of patients had surgical intervention as primary treatment (65.9%) while 20.7% were treated medically, mainly with dopamine agonists (18.5%). Most patients had inadequate disease control after first-line treatment regardless of treatment modality (79.4%).

    CONCLUSION: This registry study provides epidemiological data on patients with acromegaly in Malaysia and serves as an initial step for further population-based studies.

    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.
