MALA is a well-documented complication of anti-glycaemic therapy in diabetics while EKA is an increasingly recognized disease entity with the advent of use of sodium-glucose co-transporter-2 (SGLT-2) inhibitors. However, the occurrence of concurrent metformin-associated lactic acidosis and euglycaemic ketoacidosis (MALKA) is uncommon and rarely reported in the literature. We report an unusual case of MALKA, in a 74-year-old gentleman with no previous history of chronic kidney disease and SGLT-2 inhibitor use, who presented with altered mental status, acute renal failure and profound high anion-gap metabolic acidosis (HAGMA) with lactaemia, ketonaemia and normoglycaemia (pH 6.965, bicarbonate 3.1, creatinine 522, glucose 6.6, lactate 17.5, ketones >8). The patient was initiated on intravenous insulin infusion with dextrose-containing drip and continuous renal replacement therapy (CRRT) in the intensive care unit (ICU). The patient had a prolonged hospital stay but was eventually discharged with a normalised renal function without need for long-term dialysis. The parallel occurrence of MALA and EKA suggest a metformin-associated inhibition of gluconeogenesis. This case highlights the importance of early recognition and investigation of concurrent diabetic ketoacidosis in the presence of MALA and vice versa as MALKA benefits from both prompt institution of parenteral glucose therapy and insulin infusion and consideration of initiation of haemodialysis.","PeriodicalId":44685,"journal":{"name":"Proceedings of Singapore Healthcare","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135536488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective We aim to provide real-world experience of sucroferric oxyhydroxide use in our local cohort on maintenance haemodialysis. Methods A retrospective clinical audit was performed to review laboratory parameters of haemodialysis patients who received sucroferric oxyhydroxide over a 14-month period from December 2020 to January 2022. Sucroferric oxyhydroxide reduced serum phosphate levels effectively, with a more than 3-fold increase in the proportion of patients who were able to achieve phosphate levels of ≤5.5 mg/dL. Ferritin levels and transferrin saturation were increased, but there were no significant differences in haemoglobin levels and erythropoietin used in the long term. We showed that sucroferric oxyhydroxide was highly effective in reducing serum phosphate to recommended levels in patients receiving haemodialysis. Further prospective studies in Asian populations are warranted to confirm our findings.","PeriodicalId":44685,"journal":{"name":"Proceedings of Singapore Healthcare","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135814988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this cross-sectional study, we examined the psychological stressors of COVID-19 on hospital essential services workers and their needs at a tertiary hospital in Singapore. Methods: We conducted a study of 246 outsourced essential workers comprising housekeeping, maintenance staff, and porting staff. Psychological distress was measured by the Kessler-6 scale. We also surveyed respondents through a questionnaire on the main concerns that worried them, supportive resources available, and additional resources that would most help them. Among the survey respondents, concerns related to employment, finances, accommodation, transportation, and likelihood of receiving medical attention for COVID-19 were significantly associated with moderate to severe psychological distress ( p<0.05). Stress from isolation and fear of COVID-19 infection constituted the greatest psychosocial burdens. Respondents felt that main supportive resources came from their employers and social circles. They also listed enhanced individual ability to cope, and additional financial aid from their employers and the government would help them the most. Financial and accommodation-related stressors reflect structural factors that exacerbated the psychosocial burdens faced by non-medical hospital workers. Most respondents tended to individualise their coping strategies, which point towards the need for stronger social protections and mental health provisions for hospital essential services workers.","PeriodicalId":44685,"journal":{"name":"Proceedings of Singapore Healthcare","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41442181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aortic aneurysms in patients with TSC have been reported presenting at varying age groups. Case description: We report a case of TSC associated with an incidental finding of an abdominal aortic aneurysm in a child. Ultrasound of the abdomen revealed a renal aortic abdominal aneurysm. Computed tomographic angiogram and magnetic resonance imaging of the abdomen confirmed this finding with wall thinning over its right lateral aspect. The child underwent surgical repair of her abdominal aortic aneurysm and recovered uneventfully.

Our quality improvement (QI) project aimed to reduce length of stay (LOS) and unnecessary investigations performed for patients admitted to PAS with abdominal pain, without causing complications or delayed diagnosis of surgical conditions. The QI project consists of a standardised management workflow with stringent discharge criteria. We reviewed outcome measures of LOS, number of investigations ordered, compliance to workflow and readmission within 1-week post discharge at the end of each Plan-Do- Study-Act (PDSA) cycle and iteratively improved the workflow following QI principles. 61% of patients were admitted to PAS for non-surgical abdominal pain throughout three PDSA cycles conducted. The third cycle showed improved compliance to workflow (80.7%) with reduced median LOS by 1 day, reduced median number of blood, stool and urine investigations by 1 and reduced range of investigations ordered. Readmission and CE attendance rate 1 week after discharge was 1.6% ( n = 3), which was comparable to audit at 2.3% ( n = 4), p = 0.709.

Recent studies favour pre-operative exercise therapy to improve the outcomes of arteriovenous fistula creation.

Patients underwent a 6-week period of self-directed daily upper extremity exercises before surgery. Patients were reviewed up to 6 months post-surgery. The primary outcome investigated was change in venous and arterial diameters following exercise intervention. The secondary outcome investigated was the primary failure rate of the newly created arteriovenous fistulas. After exercise therapy, mean hand grip strength increased from 20.3 ± 6.62 kg to 21.9 ± 7.16 kg ( p=.01).
