INTRODUCTION:
This study aimed to identify risk factors that are associated with increased mortality that could prompt a serious illness conversation (SIC) among patients with chronic kidney disease (CKD).
METHODS:
The electronic health records of adult CKD patients admitted between August 2018 and February 2020 were retrospectively reviewed to identify CKD patients with >1 hospitalisation and length of hospital stay ≥4 days. Outcome measures were mortality and the duration of hospitalisation. We also assessed the utility of the Cohen's model to predict 6-month mortality among CKD patients.
RESULTS:
A total of 442 patients (mean age 68.6 years) with median follow-up of 15.3 months were identified. The mean (standard deviation) Charlson Comorbidity Index [CCI] was 6.8±2.0 with 48.4% on chronic dialysis. The overall mortality rate until August 2020 was 36.7%. Mortality was associated with age (hazard ratio [HR] 1.51, 95% confidence interval [CI] 1.29-1.77), CCI≥7 (1.58, 1.08-2.30), lower serum albumin (1.09, 1.06-1.11), readmission within 30-day (1.96, 1.43-2.68) and CKD non-dialysis (1.52, 1.04-2.17). Subgroup analysis of the patients within first 6-month from index admission revealed longer hospitalisation stay for those who died (CKD-non dialysis: 5.5; CKD-dialysis: 8.0 versus 4 days for those survived, P<0.001). The Cohen's model demonstrated reasonable predictive ability to discriminate 6-month mortality (area under the curve 0.81, 95% CI 0.75-0.87). Only 24 (5.4%) CKD patients completed advanced care planning.
CONCLUSION
CCI, serum albumin and recent hospital readmission could identify CKD patients at higher risk of mortality who could benefit from a serious illness conversation.

INTRODUCTIONIt is challenging for dialysis patients to maintain adherence to their medical regimen, and symptoms of depression are prevalent among them. Limited data is available about adherence and depression among patients receiving peritoneal dialysis (PD). This study aimed to examine the rates of treatment non-adherence and depression in PD patients.
METHODSA total of 20 PD patients (response rate 71.4%; mean age 64.4 ± 11.6 years) were assessed using the Beliefs about Medicines Questionnaire, Self Efficacy for Managing Chronic Disease Scale, Hospital Anxiety and Depression Scale (HAD) and Kidney Disease Quality of Life-Short Form. A self-reported adherence (PD exchanges, medication and diet) scale developed for the study was also included. Medical information (e.g. most recent biochemistry results) was obtained from chart review.
RESULTSThe mean self-reported scores indicated an overall high level of adherence, although a significant proportion of patients were non-adherent. Among the latter, 20% of patients were non-adherent to medication and 26% to diet due to forgetfulness, while 15% and 26% of patients admitted to deliberate non-adherence to medication and diet, respectively. Treatment modality, employment, self-care status and self-efficacy were associated with overall adherence. Using a cutoff point of 8 for HAD depression and anxiety subscales, 40% of patients were found to be depressed and 30% had symptoms of anxiety.
CONCLUSIONThis is the first study to document treatment adherence and depression among PD patients in Singapore. Findings of high prevalence of depression and anxiety, and reports of poor adherence warrant development of intervention programmes.

transmission of hepatitis B virus (HBV) infection amongchildren of hepatitis B surface antigen (HBsAg) positivemothers in Malaysia. Methods: This is a cross-sectional study of all the childrenof HBsAg-positive mothers who delivered at the Universityof Malaya Medical Centre between 1993 and 2000. Results: A total of 60 HBsAg-positive mothers and their 154children participated in the study. HBsAg was detected infour children (2.6%) while IgG antibody to the hepatitis Bcore antigen (anti-HBc IgG) was detected in seventeenchildren (11.0%). The mother’s age at childbirth wassignificantly lower in the children with detectable HBsAg(22.5±6.1 years vs. 29.7±4.5 years, p=0.043) and anti-HBc IgG(26.6±6.1 years vs. 30.0±4.3 years, p=0.004). Children born inthe 1980s were significantly more likely to have detectableHBsAg (18.8% vs. 0.7%, p=0.004) and anti-HBc IgG (37.5%vs. 8.0%, p=0.000) compared with those born later. Allchildren with detectable HBsAg were born via spontaneousvaginal delivery, and hepatitis B immunoglobulin was eithernot given or the administration status was unknown. Themajority of mothers with chronic HBV infection (70.4%) werenot under any regular follow-up for their chronic HBVinfection and the main reason was the lack of awareness ofthe need to do so (47.4%). Conclusion: Transmission of HBV infection among childrenof HBsAg-positive mothers in Malaysia is low. However,attention needs to be given to the high rate of HBsAg-positive mothers who are not on any regular follow-up.

INTRODUCTIONDiabetes mellitus (DM) is a major cause of chronic kidney disease (CKD). The epidemiology of CKD secondary to type 2 DM (T2DM) (i.e. diabetic nephropathy (DN)) has not been well studied in Singapore, a multi-ethnic Asian population. We aimed to determine the prevalence of CKD in adult patients with T2DM.
MATERIALS AND METHODSWe conducted a cross-sectional study on patients (n = 1861) aged 21 to 89 years with T2DM who had attended the DM centre of a single acute care public hospital or a primary care polyclinic between August 2011 and November 2013. Demographic and clinical data were obtained from patients using a standard questionnaire. Spot urine and fasting blood samples were sent to an accredited hospital laboratory for urinary albumin, serum creatinine, HbA1c and lipid measurement. CKD was defined and classified using the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) guidelines and classification.
RESULTSThe distribution by risk of adverse CKD outcomes was: low risk, 47%; moderate risk, 27.2%; high risk, 12.8%; and very high risk, 13%. The prevalence of CKD in patients with T2DM was 53%. Variables significantly associated with CKD include neuropathy, blood pressure ≥140/80 mmHg, triglycerides ≥1.7 mmol, body mass index, duration of diabetes, HbA1c ≥8%, age, cardiovascular disease, and proliferative retinopathy.
CONCLUSIONCKD was highly prevalent among patients with T2DM in Singapore. Several risk factors for CKD are well recognised and amenable to intervention. Routine rigorous screening for DN and enhanced programme for global risk factors reduction will be critical to stem the tide of DN.

INTRODUCTIONWe aimed to evaluate the effectiveness and safety of canagliflozin as compared to sitagliptin in a real-world setting among multiethnic patients with Type 2 diabetes mellitus (T2DM) in Singapore.
METHODSThis was a new-user, active-comparator, single-centre retrospective cohort study. Patients aged 18-69 years with T2DM and estimated glomerular filtration rate ≥ 60 mL/min/1.73 m were eligible for inclusion if they were initiated and maintained on a steady daily dose of canagliflozin 300 mg or sitagliptin 100 mg between 1 May and 31 December 2014, and followed up for 24 weeks.
RESULTSIn total, 57 patients (canagliflozin 300 mg, n = 22; sitagliptin 100 mg, n = 35) were included. The baseline patient characteristics in the two groups were similar, with overall mean glycated haemoglobin (HbA1c) of 9.4% ± 1.4%. The use of canagliflozin 300 mg was associated with greater reductions in HbA1c (least squares [LS] mean change -1.6% vs. -0.4%; p < 0.001), body weight (LS mean change -3.0 kg vs. 0.2 kg; p < 0.001) and systolic blood pressure (LS mean change: -9.7 mmHg vs. 0.4 mmHg; p < 0.001), as compared with sitagliptin 100 mg. About half of the patients on canagliflozin 300 mg reported mild osmotic diuresis-related side effects that did not lead to drug discontinuation.
CONCLUSIONOur findings suggest that canagliflozin was more effective than sitagliptin in reducing HbA1c, body weight and systolic blood pressure in patients with T2DM, although its use was associated with an increased incidence of mild osmotic diuresis-related side effects.

OBJECTIVES: An inter-arm difference in systolic blood pressure (IADSBP) of 10 mmHg or more has been associated with cardiovascular disease (CVD) and increased mortality in T2DM patients. We aim to study ethnic disparity in IADSBP and its determinants in a multi-ethnic T2DM Asian cohort.
METHODOLOGY: Bilateral blood pressures were collected sequentially in Chinese (n=654), Malays (n=266) and Indians (n=313). IADSBP was analyzed as categories (
RESULTS: Malays (27.4%) and Indians (22.4%) had higher prevalence of IADSBP ?10 mmHg than Chinese (17.4%) (p=0.002). After adjustment for age, gender, duration of diabetes, hemoglobin A1c, body mass index (BMI), heart rate, pulse wave velocity (PWV), estimated glomerular filtration rate (eGFR), albumin-to-creatinine ratio (ACR), smoking, hypertension, soluble receptor for advanced glycation end products (sRAGE), and usage of hypertension medications, ethnicity remained associated with IADSBP. While Malays were more likely to have IADSBP ?10 mmHg than Chinese (OR=1.648, 95%CI: 1.138-2.400, p=0.009), Indians had comparable odds with the Chinese. BMI (OR=1.054, 95%CI: 1.022-1.087, p=0.001) and hypertension (OR=2.529, 95%CI: 1.811-3.533, p<0.001) were also associated with IADSBP ?10 mmHg.
CONCLUSION: IADSBP in Malays were more likely to be ?10 mmHg than the Chinese which may explain their higher risk for CVD and mortality. Measuring bilateral blood pressures may identify high-risk T2DM individuals for intensive risk factor-management.
