Introduction: Holistic Approach in Lowering and Tracking Chronic Kidney Disease (HALT-CKD) is a nationwide programme that was introduced in 2017 to combat CKD in Singapore. This study aims to evaluate outcomes of the HALT-CKD programme and identify factors influencing disease progression among early CKD patients.

Method: We conducted a retrospective cohort study involving adult patients aged 21 to 80 with CKD stages G1-G3A, recruited from 5 Singapore polyclinics between 2017 and 2018. The primary outcome-time to progression to advanced CKD (G3B-G5)-was tracked until March 2023, based on patients' last known serum creatinine levels. Descriptive statistics and Cox regression were used. Patients who followed up with other institutions, were deceased or defaulted without developing (or experiencing) the outcome were censored.

Results: We studied 3800 patients (mean age: 61.9 years) for a median of 4.7 years. Among them, 12.6% developed advanced CKD despite statistically significant improvements in HbA1c, blood pressure and albuminuria levels. Increasing age, female sex, clinic, baseline creatinine, diastolic blood pressure and HbA1c significantly shortened time to CKD progression. Macro-albuminuria at baseline (hazard ratio [HR] 1.77, 95% confidence interval [CI] 1.19- 2.61) and at analysis (HR 2.22, 95% CI 1.55-3.19) significantly accelerated advanced CKD progression. Patients who had their angiotensin-converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB) dose reduced or discontinued progressed to advanced CKD earlier (HR 1.92, 95% CI 1.50-2.45). Counselling and sodium-glucose cotransporter-2 inhibitor (SGLT2i) use did not significantly delay CKD progression.

Conclusion: Maintaining optimal ACEi/ARB dosage is essential to delay CKD progression. Premature cessation or reduction of this dosage should be discouraged. Further research on counselling and SGLT2i use in early CKD is needed to address the growing burden of CKD.

Introduction: Singapore has implemented an evidence-based smoking cessation framework to support smokers in quitting. Our study investigated the prevalence and correlates of (1) quit attempts (QA) and quit intentions (QI) among current smokers, and (2) smoking cessation (SC) among ever-smokers in Singapore.

Method: Data was collected from a nationwide survey conducted between 2020 and 2022. QA was defined as attempting to stop smoking at least once in the past 12 months, while QI was defined as planning to quit smoking within the next 30 days or the next 6 months. SC referred to individuals who quit smoking over 6 months ago. Sociodemographic factors, doctor's advice to quit and perceived harm from smoking were assessed using logistic regression among current smokers (n=1024) and ever-smokers (n=1457).

Results: Among current smokers, 31.3% and 41.2% reported QI and QA, respectively. Smokers with secondary or pre-tertiary education were less likely to report QI compared to those with a degree or higher. Doctor's advice to quit was associated with a higher likelihood of QA. Among ever-smokers, 25.3% reported SC, and this was more likely when they perceived smoking 1 or more packs of cigarettes daily as posing a moderate or high health risk.

Conclusion: Educational campaigns should focus on simplifying messages for individuals with lower literacy levels. Smoking cessation training can be incorporated into medical education, and graphic health warnings on cigarette packs can help effectively communicate the dangers of smoking.

Introduction: The global incidence of dementia is increasing, and cognitively impaired drivers are at a higher risk of crashes compared to healthy drivers. Doctors face challenges in assessing these at-risk drivers, with questionable adherence to existing guidelines. This study aimed to review and compare guidelines for managing cognitively impaired drivers from various countries.

Method: A scoping review was conducted to identify relevant guidelines, which were then descriptively compared with Singapore's guideline.

Results: Eleven guidelines from 8 countries: US (n=2), Canada (n=2), UK (n=2), Ireland, Belgium, Australia, New Zealand and Singapore were reviewed. All guidelines support driving assessments and conditional licensing in ordinary (i.e. non-professional) drivers with dementia. Canada stands out for not allowing co-piloting and geographical restrictions in conditional licensing practice. Few guidelines provide indemnity for doctors reporting to licensing authorities, and communication about the impact of dementia on car insurance is rarely addressed. Most Western guidelines include evidence-based approaches, provisions for drivers with mild cognitive impairment and early discussions on transitioning from driving. A clinic-based functional screening toolbox and 2 clinical algorithms (1 with and 1 without the Clinical Dementia Rating scale) were identified as having universal applicability. Singapore's guideline, by comparison, is outdated and lacks both developmental rigour and guidance on managing mild cognitive impairment and transitioning drivers out of driving.

Conclusion: Comprehensive, evidence-based guidelines from Western countries provide valuable resources that can help Singapore design or update its guideline.

Introduction: Intolerance frequently limits the use of intragastric balloons (IGBs) in the treatment of obesity. This includes refractory nausea, vomiting and abdominal discomfort. Our study aims to identify predictors of balloon intolerance and early removal, which will help to guide patient selection for this intervention and peri-procedure care.

Method: We conducted a retrospective cohort study of 54 consecutive patients who underwent IGB insertion from July 2017 to July 2022 in a single tertiary institution in Singapore. Forty-seven (87.0%) patients completed therapy, while 7 patients (13.0%) had early removal of the balloon due to intolerance. Characteristics of both groups were compared.

Results: Multivariate analysis revealed significant associations between early balloon removal and both depression (P=0.012) and anxiety (P=0.001) after adjusting for age, sex, ethnicity, height, nulliparity, balloon type and volume. Univariate analysis revealed that anxiety was the main risk factor (P=0.004, odds ratio 9.111, 95% confidence interval 1.624-51.124), while depression was no longer a significant predictor.

Conclusion: Identifying predictors of balloon intolerance and early removal can enhance patient selection and improve peri-procedural care. In patients with a history of depression or anxiety, it is important to ensure adequate counselling and preparation prior to balloon insertion.
