Background:
There is a dearth of data on Filipino patients with autoimmune hepatitis (AIH). We aimed to describe the
demographic and clinical profiles of patients with AIH and to characterize clinical outcomes and treatment responses.
Methods:
A retrospective cohort study involving patients from two tertiary centers diagnosed with AIH from January 1, 2007, to December 31, 2019, was included. Disease remission was defined as the normalization of ALT levels, while failure was defined as an increase in ALT levels over baseline or clinical deterioration.
Results:
A total of 48 patients were identified between 2007 to 2019. The median age at presentation was 51 (27-79 yrs.). Liver cirrhosis was already present in 37.5% (27.1% decompensated) on diagnosis. Aside from a higher histologic activity index in females (p=0.047), there were no gender-specific differences. Disease remission was achieved in 41.9% of patients at 6 months, while only 9.3% failed. At the final disposition, remission rates had slightly increased to 58%, but failure rates had risen to 12%. Treatment responses at both 6 and 12 months and MELD and Child-Pugh class influenced treatment responses at final disposition. Median overall survival was 102 weeks and was influenced by the presence of liver dysfunction and 12 months and final treatment responses.
Conclusion
Autoimmune hepatitis remains an important cause of morbidity and mortality. The results of the study
highlight the need for immunosuppressive therapy to induce early remission for a higher likelihood of subsequent biochemical remission to reduce the risk of liver-related mortality.

Background:
Weight loss, though difficult to attain and sustain over time, remains the cornerstone of non-alcoholic fatty liver disease (NAFLD) treatment. We aimed to describe weight changes among NAFLD patients.
Methods:
This was a retrospective, cohort study of consecutively-identified NAFLD patients with >2 clinic visits from March2007–April2018. Weight changes from baseline were categorized into weight gain, weight loss, and no change. Baseline liver and metabolic biochemistries and non-invasive liver fibrosis tests were correlated with the final weight changes. Succeeding weight changes after the initial follow-up visits were used to determine sustainability of weight loss.
Results:
Of the 240 patients included, 123 (51.2%), 93 (38.8%), and 24 (10%) had weight gain, weight loss, and no change, respectively. Only 12.5% had >5% weight loss. Duration of follow-up was significantly longer for patients with weight loss (p<0.001). None of the baseline demographic and laboratory data were associated with weight loss. Patients with weight loss also did not have significant changes to their biochemistries and non-invasive liver fibrosis tests compared to patients with weight gain/no change. Compared to patients with weight gain after the initial follow-up, where only 11.8% were able to lose weight on the final visit, 73.1% of patients who lost weight after the initial follow-up were able to sustain their weight loss on the final visit.
Conclusions
Weight loss is achieved in only a third of NAFLD patients. Although 73% of patients who lost weight initially were able to sustain it, patients who gained weight after the 1st follow-up were unlikely to lose weight on further follow-up.

Peritoneal dialysis (PD) is the only well-established home-based dialysis therapy in Singapore. As it is a home-based modality, PD should be considered as a preferred mode of kidney replacement therapy (KRT) for patients with kidney failure during this COVID-19 pandemic as it avoids frequent visits to hospitals and/or satellite dialysis centres. The highly infectious nature of this virus has led to the implementation of the Disease Outbreak Response System Condition orange status in Singapore since early February 2020. This paper summarises the strategies for management of several aspects of PD in Singapore during this COVID-19 pandemic, including PD catheter insertion, PD training, home visit and assisted PD, outpatient PD clinic, inpatient management of PD patients with or without COVID-19 infection, PD as KRT for COVID-19 patients with acute kidney injury, management of common complications in PD (peritonitis and fluid overload), and management of PD inventory.

Obstructive sleep apnoea (OSA), a sleep-related breathing condition, is diagnosed based on a patient's apnoea-hypopnea index from a sleep study, and the presence or absence of symptoms. Diabetes mellitus (DM) and OSA share a significant common risk factor, obesity, with all three conditions contributing to the risk of developing cardiovascular diseases. The pathophysiological links between OSA and DM are still unclear, but intermittent hypoxia may be an important mechanism. More awareness of the possible link between OSA and DM is needed, given their increasing prevalence locally and worldwide. Continuous positive airway pressure is the standard treatment for OSA, while weight loss through dietary and lifestyle modifications is important to holistically manage patients with either condition. There is currently insufficient evidence to support the benefits of screening every diabetic patient for OSA. However, diabetic patients with symptoms suggestive of OSA should be referred to a sleep specialist for further evaluation.

INTRODUCTIONParenteral nutrition (PN) is indicated for patients who are unable to progress to oral or enteral nutrition. There are no local studies done on estimating the cost of PN in acute settings. The aims of this study are to describe the demographics, costs of PN and manpower required; and to determine the avoidable PN costs for patients and hospital on short-term PN.
MATERIALS AND METHODSPatient data between October 2011 and December 2013 were reviewed. Data collected include demographics, length of stay (LOS), and the indication/duration of PN. PN administration cost was based on the cost of the PN bags, blood tests and miscellaneous items, adjusted to subsidy levels. Manpower costs were based on the average hourly rate.
RESULTSCosts for PN and manpower were approximately S$1.2 million for 2791 PN days. Thirty-six cases (18.8%) of 140 PN days were short-term and considered to be avoidable where patients progressed to oral/enteral diet within 5 days. These short-term cases totalled $59,154.42, where $42,183.15 was payable by the patients. The daily costs for PN is also significantly higher for patients on short-term PN (P <0.001).
CONCLUSIONIn our acute hospital, 90% of patients referred for PN were surgical patients. Majority of the cost comes from the direct daily cost of the bag and blood tests, while extensive manpower cost was borne by the hospital; 18.8% of our cohort had short-term avoidable PN. Daily PN may cost up to 60% more in patients receiving short-term PN. Clinicians should assess patient's suitability for oral/enteral feeding to limit the use of short-term PN.

INTRODUCTIONBreast cancer is the leading cancer among women in Singapore. Five years after a population-wide breast cancer screening programme was introduced, screening rates remained relatively low at 41%. Studies have shown decreased screening propensity among medically underserved women typically of minority or socioeconomically disadvantaged status. We conducted a quasi-randomised pragmatic trial aimed at encouraging mammography screening among underscreened or unscreened women in a publicly funded primary care facility in Singapore.
MATERIALS AND METHODSThe study was conducted from May to August 2010. Components of intervention included (1) tailored education, (2) doctor's reminder, and (3) cost reduction. Researchers administered a structured questionnaire to eligible female polyclinic attendees and patient companions aged 40 to 69 years. Individual knowledge, attitudes, beliefs, and barriers towards mammography screening were identified and educational messages tailored. Doctor's reminder and cost reduction were implemented additively.
RESULTSOverall, out of 448 participants, 87 (19.4%, 95% confidence interval (CI), 15.8% to 23.1%) completed mammography screening across 3 arms of study. Participants who received a cost reduction were more likely to attend screening compared to participants in other intervention arms (adjusted odds ratio (OR) 2.4, 95% CI, 1.2 to 4.5, P = 0.009). Cost of screening, ethnicity, prior screening history, and attitudes towards mammography screening were identified as significant factors predicting mammogram attendance.
CONCLUSIONIncluding a cost reduction component was the most effective intervention that increased mammography screening rates. Women's underlying beliefs, attitudes, and other predisposing factors should also be considered for integration into existing breast cancer screening programmes.

INTRODUCTIONThe near terminal patient with skeletal metastasis may suitably be palliated with an intramedullary nail whereas another patient with good survival potential may benefit from a more extensive resection and reconstructive procedure. In a previous study by the senior author (Nathan et al, 2005), life expectancy in patients operated on for bone metastases correlated with clinical and haematological parameters in a normogram. We performed a cross-cultural comparison to validate this normogram.
MATERIALS AND METHODSWe randomly selected 73 patients who had undergone surgery for metastatic bone disease between 28 December 2000 and 11 March 2009. The time to deaths was recorded from hospital records and telephone interviews. Multiple parameters including clinical, radiological and haematological were evaluated for significant prognostic value using Kaplan-Meier survivorship analysis. Statistically significant parameters were entered into a Cox regression model for statistically independent significance. A multi-tier prediction of survival was performed by workers from various levels of seniority.
RESULTSAt the time of analysis, there were 40 deaths (55%). Median survival was 15.8 (95% CI, 7.9 to 23.7) months. Kaplan-Meier analysis showed that low haemoglobin (P = 0.0000005), presence of lymph node metastases (P = 0.00008), multiple bone metastases (P = 0.003), presence of visceral metastases, (P = 0.007), low lymphocyte count (P = 0.02) and low serum albumin (P = 0.02) were significantly associated with poor survival. By Cox regression analysis, presence of visceral metastases (P = 0.002), presence of lymph node metastases (P = 0.0002) and low haemoglobin (P = 0.01) were shown to be independent factors in the prediction of survival. Survivorship readings were superimposed onto the previous normogram and found to be similar. Independent blinded use of the normogram allowed good prediction of survival. There was a tendency to underestimate survival when patients survived beyond 1 year of skeletal metastasis.
CONCLUSIONOur findings are similar to that of the previous study in showing a relationship between the above-mentioned parameters and survival. This is despite differences in patient demographic characteristics and management protocols. Use of the tools may allow better siting of most appropriate surgery in metastatic bony disease.

INTRODUCTIONThis study evaluates determinants, expectations, association with quality of life (QOL) and doctor's awareness of Complementary and Alternative Medicine (CAM) use in Singapore cancer patients.
MATERIAL AND METHODSWe interviewed 316 patients visiting the Cancer Centre of the National University Hospital on behaviour, attitudes and expectations towards CAM and assessed QOL via Euroqol Questionnaire (EQ-5D). Medical information was obtained from oncologists.
RESULTSOne hundred and seventy-three patients (55%) reported CAM use after cancer diagnosis. Chinese ethnicity, tertiary education, age <65 years and previous CAM use were independent predictors of CAM use. Fifty-one per cent of CAM users informed their doctors about their use and 15% of doctors reported to be aware of CAM use in these patients. Thirty-seven per cent believed CAM to be equally or more effective than conventional cancer therapies and 78% expected at least basic knowledge about CAM from their oncologists. Twenty-fi ve per cent of patients reported concurrent use of oral CAM and chemotherapy, of which oncologists were unaware in 86% of cases. CAM users had higher EuroQol utility scores than non-CAM users (0.79 versus 0.73, respectively, P = 0.03), in particularly those aged >or=65 years and those with stage IV disease.
CONCLUSIONSingapore cancer patients show high prevalence of CAM use, high expectations regarding its effectiveness and doctors' knowledge on CAM and many use it concurrently with chemotherapy or radiotherapy. Since oncologists are generally unaware of CAM use in their patients, doctor-patient communication on CAM use needs to be improved. The association of CAM use and higher QOL scores in some subgroups deserves further exploration.
