Recent epidemics and pandemics have highlighted a number of ethical concerns about the response to the increasing threat of emerging infectious diseases. Some of these ethical concerns are very fundamental. They include why a pandemic was declared, how much clinical information can be collected for public health without threatening patient confidentiality and how to ensure fairness in the distribution of resources. We discuss these issues and suggest approaches to resolve these dilemmas as we anticipate the next pandemic.

Objective: This study aims to determine the quality of life (QOL) of Malaysian women based on their physical and mental scores and correlates with age and cervical disease severity. Methods: This is a cross-sectional study from Nov 2006 till Dec 2007 from participating Gynecology-Oncology outpatient and in patient’s wards. QOL interviews used the SF-36 questionnaires. Main domains were the Physical Composite Scores (PCS) and the Mental Composite Scores (MCS). Results: A total of 396 participated in the study. Mean respondents age were 53.31 ± 11.21 years, educated till secondary level (39.4%), Malays (44.2%) with mean marriage duration of 27.73 ± 12.12 years. Among pre-invasive diseases, the cervical intra epithelial neoplasia (CIN) 1 was the highest in percentage of cases (8.1%). Among invasive cancer, stage 1 cancer was highest (31.1%), followed with stage 2 (28.3%), stage 3 (7.3%) and stage 4 cancers (5.8%). PCS scores are highest among the pre-invasive and stage 1 cancer (F=4.357; p<0.0001) and influenced by age and income. MCS were not significantly influenced by age or stage of cervical diseases (F= 1.393; p=0.206) but the regression model showed that amount spent on health care was a significant factor. Conclusion: Cervical diseases posed a substantial cause in reducing QOL with increasing age and disease severity. This disability can be reduced with early screening and intervention to prevent disease progression. Reducing disease burden play a role to improve QOL among at risk women before developing late stages of disease.

Fecal occult blood test (FOBT) screening has been shown to decrease the incidence and mortality of colorectal cancer (CRC). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the immunochemical fecal occult blood test (i-FOBT) in diagnosing CRC were assessed among the patients in a tertiary referral hospital in Malaysia. A total sample of 814 patients aged 16 to 85 years old who performed i-FOBT and endoscopic screenings was obtained. The patients were recruited for a retrospective investigation. Sensitivity, specificity, PPV, and NPV were derived for the CRC screenees. Out of the 814 patients screened using i-FOBT, half of them were above 59 years old (49.6%), and 36% had positive i-FOBT. Gender distribution was almost equal, where 53.4% of the patients were female, and 46.6% were male. Majority of the patients were Malays (56.6%), followed by Chinese (24.0%), Indians (16.5%), and others (2.9%). Among the 71 patients referred for colonoscopy, 57.7% and 42.3% corresponded to positive and negative i-FOBT cases, respectively. Polyps were found to be most common among the patients (25.6%), 7.0% were found positive for invasive CRC, and 35.2% had normal colonoscopic findings. There was a significant association between colonoscopic finding and positive i-FOBT (p=0.001). The sensitivity, specificity, PPV, and NPV for CRC detection were 66.7%, 43.0%, 9.8%, and 93.3%, respectively. The results indicate that i-FOBT is a useful tool in the detection of abnormalities in the lower gastrointestinal tract and therefore serves as a cornerstone for potential large-scale screening programmes.

INTRODUCTIONThe incidence of cough induced by angiotensin-converting enzyme (ACE) inhibitors has been reported to be 5%-20%, with less than half of affected patients requiring discontinuation due to persistent cough. However, the incidence in the local Asian population has not been studied. This study aimed to objectively evaluate the incidence of discontinuation of ACE inhibitors due to cough, in a primary healthcare centre in Singapore.

METHODSWe retrospectively reviewed the medical records, both electronic and written, of patients who attended Tampines Polyclinic to identify those who were newly prescribed ACE inhibitors. The written medical records were analysed to identify patients who discontinued the use of ACE inhibitors and to find out the reasons for discontinuation.

RESULTSA total of 424 patients were identified during the study period. Out of the 424 patients, 129 (30.4%) discontinued the use of ACE inhibitors due to cough. Overall, 90 (21.2%) patients who were initially started on ACE inhibitors were eventually switched to angiotensin receptor blockers (ARBs).

CONCLUSIONIn our cohort, the incidence of discontinuation of ACE inhibitors due to cough is higher than most other studies. The relationship between ethnicity and tolerance of medications should not be underestimated. As there is a high incidence of discontinuation of ACE inhibitors due to cough in the local population, ARBs may be a reasonable substitute as a first-line medication, if clinically indicated.

Background: Management of COVID--19 patients during surges have been a challenge as hospitals have to deal with staff, room, and medication shortages. Among these medications is tocilizumab which is given to patients with severe/critical conditions. In Ospital ng Makati, patients are given baricitinib as alternative immunomodulator to prevent possible cytokine storm during tocilizumab shortages. The current recommendation for baricitinib is to give it in addition to dexamethasone and remdesivir for hospitalized COVID-19 patients requiring low to high-flow oxygen, and non-invasive ventilation. However, there is not enough evidence to recommend it as an alternative to tocilizumab in COVID--19 patients. This study aims to find out the real-world efficacy of baricitinib in addition to standard of care among admitted patients with severe COVID-19 pneumonia admitted in Ospital ng Makati. Methods: This is a retrospective, case control study that reviewed records of adult patients admitted at Ospital ng Makati from December 2020 to May 2021 due to severe COVID-19. Patients who were given standard of care was compared to those who were given baricitinib by measuring the duration of clinical improvement, in-hospital all-cause mortality, number of hospital stay, and progression to acute respiratory distress syndrome (ARDS) and need for mechanical ventilator. Results: The use of baricitinib led to a faster improvement time (10 vs 12 days) however did not reach level of significance (p=0.069). There was also no significant difference in the mortality, number of hospital days, and progression to ARDS between the two groups. Conclusion There is not enough evidence to recommend baricitinib as an alternative to tocilizumab in patients with severe COVID--19 infection.

The efficacy and safety of a single tablet regimen (STR) of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) were analyzed in Phase 3 clinical trials in antiretroviral therapy (ART)-naïve and ART-experienced Asian subjects infected with human immunodeficiency virus (HIV)-1. Studies GS-US-236-102 and GS-US-236-103 were randomized, double-blind, placebo-controlled, 144-week studies conducted in ART-naïve subjects, comparing E/C/F/TDF versus efavirenz (EFV)/F/TDF or ritonavir-boosted atazanavir (ATV+RTV) plus emtricitabine/tenofovir DF (F/TDF), respectively. Studies GS-US-236-115 and GS-US-236-121 were randomized, open-label, 96-week long conducted in ART-experienced subjects, who switched to E/C/F/TDF from ritonavir-boosted protease inhibitors (PI+RTV)+F/TDF, or non-nucleoside reverse transcriptase inhibitors (NNRTI)+F/TDF regimens. The E/C/F/TDF appeared to have sustained efficacy and safety and was well tolerated in the small number of ART-naïve and ART-experienced Asian subjects.

INTRODUCTIONPneumonia is associated with considerable mortality. However, there is limited information on age-specific prognostic factors for death from pneumonia.

METHODSPatients hospitalised with a diagnosis of pneumonia through the emergency department were stratified into three age groups: 18-64 years, 65-84 years and ≥ 85 years. Multivariate logistic regression and receiver operating characteristic curve analyses were conducted to evaluate prognostic factors for mortality and the performance of pneumonia severity scoring tools for mortality prediction.

RESULTSA total of 1,902 patients were enrolled (18-64 years: 614 [32.3%]; 65-84 years: 944 [49.6%]; ≥ 85 years: 344 [18.1%]). Mortality rates increased with age (18-64 years: 7.3%; 65-84 years: 16.1%; ≥ 85 years: 29.7%; p < 0.001). Malignancy and tachycardia were prognostic of mortality among patients aged 18-64 years. Male gender, malignancy, congestive heart failure and eight other parameters reflecting acute disease severity were associated with mortality among patients aged 65-84 years. For patients aged ≥ 85 years, altered mental status, tachycardia, blood urea nitrogen, hypoxaemia, arterial pH and pleural effusion were significantly predictive of mortality. The Pneumonia Severity Index (PSI) was more sensitive than CURB-65 (confusion, uraemia, respiratory rate ≥ 30 per minute, low blood pressure, age ≥ 65 years) for mortality prediction across all age groups.

CONCLUSIONThe predictive effect of prognostic factors for mortality varied among patients with pneumonia from the different age groups. PSI performed significantly better than CURB-65 for mortality prediction, but its discriminative power decreased with advancing age.

INTRODUCTION: Singapore has had three medical schools since 2013. We undertook a cross-sectional quantitative national survey to determine the financial impact of medical education on medical students in Singapore. METHODS: All 1,829 medical students in Singapore were invited to participate in this study. Information on demographics, financial aid utilisation and outside work was collected and analysed. RESULTS: 1,241 (67.9%) of 1,829 students participated in the survey. While the overall proportion of students from households with monthly incomes < SGD 3,000 was only 21.2% compared to the national figure of 31.4%, 85.4% of medical students expected to graduate with debts > SGD 75,000. There were significant differences in per capita incomes among the schools, with 54.5%, 23.3% and 7.8% of Duke-NUS Medical School (Duke-NUS), NUS Yong Loo Lin School of Medicine (NUS Medicine) and Lee Kong Chian School of Medicine (LKCMedicine) students, respectively, reporting a per capita income of < SGD 1,000 (p < 0.001). There were significant differences in financial support: 75.0%, 34.1% and 38.8% of Duke-NUS, NUS Medicine and LKCMedicine students, respectively, received financial aid (p < 0.001). The top reasons for not applying for aid included a troublesome application process (21.4%) and the perception that it would be too difficult to obtain (21.0%). CONCLUSION Students in the three medical schools in Singapore differ in their financial needs and levels of financial support received. A national approach to funding medical education may be needed to ensure that financial burdens do not hamper the optimal training of doctors for Singapore's future.

INTRODUCTIONPeak currents are the final arbiter of defibrillation in patients with ventricular fibrillation (VF). However, biphasic defibrillators continue to use energy in joules for electrical conversion in hopes that their impedance compensation properties will address transthoracic impedance (TTI), which must be overcome when a fixed amount of energy is delivered. However, optimal peak currents for conversion of VF remain unclear. We aimed to determine the role of peak current and optimal peak levels for conversion in collapsed VF patients.

METHODSAdult, non-pregnant patients presenting with non-traumatic VF were included in the study. All defibrillations that occurred were included. Impedance values during defibrillation were used to calculate peak current values. The endpoint was return of spontaneous circulation (ROSC).

RESULTSOf the 197 patients analysed, 105 had ROSC. Characteristics of patients with and without ROSC were comparable. Short duration of collapse < 10 minutes correlated positively with ROSC. Generally, patients with average or high TTI converted at lower peak currents. 25% of patients with high TTI converted at 13.3 ± 2.3 A, 22.7% with average TTI at 18.2 ± 2.5 A and 18.6% with low TTI at 27.0 ± 4.7 A (p = 0.729). Highest peak current conversions were at < 15 A and 15-20 A. Of the 44 patients who achieved first-shock ROSC, 33 (75.0%) received < 20 A peak current vs. > 20 A for the remaining 11 (25%) patients (p = 0.002).

CONCLUSIONFor best effect, priming biphasic defibrillators to deliver specific peak currents should be considered.

INTRODUCTIONIncreasing financial challenges have resulted in great debt among medical graduates worldwide. In Singapore, more scholarships and bursaries have been disbursed in recent years to support students who are financially challenged. We aimed to study the financial status of medical students in National University of Singapore (NUS) Yong Loo Lin School of Medicine (i.e. NUS Medicine), Singapore, and the financial support available to them.

METHODSA cross-sectional quantitative study was performed. Surveys were distributed and completed by medical students of NUS Medicine. Information regarding household income, financial assistance, monthly allowance and expense, and concurrent occupations was collected. We compared our findings with the results of a similar study performed in 2007 and national income data.

RESULTSA total of 956 (66.2%) out of 1,445 medical students completed the survey. 19.5% and 58.5% of respondents came from households with monthly incomes < SGD 3,000 and > SGD 7,000, respectively. 20.6% of students had loans, 18.9% had scholarships and bursaries, and 14.4% worked to support themselves.

CONCLUSIONMedical school fees have risen by more than 50% over the past ten years. Our study found that there were increases in the proportion of students from both the lower- and higher-income segments, with proportionally fewer students from the middle-income segment. A large number of students were working and/or had some form of financial support. More should be done to meet the needs of financially challenged medical students to ensure equal access to quality medical education.
