Introduction: This study aimed to determine the prevalence and factors associated with psychological distress following the COVID-19 pandemic among medical students at one of the public universities in Malaysia. Method:
From August to October 2020, a web-based cross-sectional study was conducted among undergraduate medical
students at a public university. DASS-21, Brief Resilience Scale and WHOQOL-Bref questionnaires were used in this
study. Results: The prevalence of depression was 40.5%, anxiety 46.0% and stress 30.9%. Based on multivariate
logistic regression, a higher quality of life score is associated with a lower likelihood of depression (AOR=0.583,
p<0.001), anxiety (AOR=0.726, p<0.001), and stress, (AOR=0.702, p<0.001) respectively. Likewise, a higher resilience score is less likely to be associated with depression (AOR=0.880, p=0.002), anxiety (AOR=0.880, p=0.002),
and stress (AOR=0.850, p<0.001). Older age (OR=0.700, p=0.020) was associated with less stress and being on
campus (OR=3.436, p=0.021) was at risk of stress during the COVID-19 pandemic. Conclusion: Our results suggest
that medical students with higher quality of life and resilience scores had less depression, anxiety and stress. Older
age was associated with less stress, and during the COVID-19 pandemic, being on campus was at risk of stress. Various stakeholders need to keep these findings in mind and identify those who are at risk for developing depression,
anxiety, and stress in order to take further action to improve their quality of life and resilience

INTRODUCTION:
Primary care physicians face the increasing burden of managing multimorbidities in an ageing population. Implementing an integrated care team (ICT) with defined roles and accountability to share consultation tasks is an emerging care model to address this issue. This study compared outcomes with ICT versus usual care for patients with multimorbidities in primary care.
METHODS:
Data was retrospectively extracted from the electronic medical records (EMRs) of consecutive adult Asian patients empanelled to ICT and those in UC at a typical primary care clinic (polyclinic) in eastern Singapore in 2018. The study population had hypertension, and/or hyperlipidaemia and/or type 2 diabetes mellitus (T2DM). Clinical outcomes included the proportion of patients (ICT vs. UC) who attained their treatment goals after 12 months. Process outcomes included the proportion of patients who completed annual diabetic eye and foot screenings, where applicable.
RESULTS:
Data from 3,302 EMRs (ICT = 1,723, UC = 1,579) from January 2016 to September 2017 was analysed. The ICT cohort was more likely to achieve treatment goals for systolic blood pressure (SBP) (adjusted odds ratio [AOR] = 1.52, 95% confidence interval [CI] = 1.38-1.68), low-density lipoprotein cholesterol (AOR = 1.72, 95% CI = 1.49-1.99), and glycated haemoglobin (AOR = 1.28, 95% CI = 1.09-1.51). The ICT group had higher uptake of diabetic retinal screening (89.1% vs. 83.0%, P < 0.001) and foot screening (85.2% vs. 77.9%, P < 0.001).
CONCLUSION
The ICT model yielded better clinical and process outcomes than UC, with more patients attaining treatment goals.

INTRODUCTION:
Lifestyle activities, such as regular physical activity, are important for good metabolic health and the prevention of non-communicable diseases. Epidemiological studies highlight an increase in the proportion of overweight children in Singapore. A workgroup was formed to develop recommendations to encourage children and adolescents (aged 7-17 years) to adopt a holistic approach towards integrating beneficial activities within a daily 24-hour period for good metabolic and general health.
METHODS:
The Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence to Decision framework was employed to formulate the public health question, assess the evidence and draw conclusions for the guide. The evidence for international 24-hour movement guidelines, and guidelines for physical activity, sedentary behaviour, and sleep and eating habits were reviewed. An update of the literature review from August 2018 to end of September 2020 was conducted through an electronic search of Medline and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases.
RESULTS:
Ten consensus statements were developed. The statements focused on the overall aim of achieving good metabolic health through integration of these activities and initiatives: light and moderate- to vigorous-intensity physical activity on a regular basis; muscle- and bone-strengthening activities; limiting sedentary behaviour; regular and adequate sleep; good eating habits and choosing nutritionally balanced foods and drinks; practise safety in exercise; and aiming to achieve more or all aforementioned recommendations for the best results.
CONCLUSION
This set of recommendations provides guidance to encourage Singapore children and adolescents to adopt health-beneficial activities within a 24-hour period.

INTRODUCTION:
The cost-effectiveness of screening asymptomatic non-alcoholic fatty liver disease (NAFLD) patients remains debatable, with current studies assuming lifelong benefits of NAFLD screening while neglecting cardiovascular outcomes. This study aims to assess the cost-effectiveness of NAFLD screening among type 2 diabetes mellitus (T2DM) patients, and to establish a price threshold for NAFLD treatment, when it becomes available.
METHOD:
A Markov model was constructed comparing 4 screening strategies (versus no screening) to identify NAFLD with advanced fibrosis among T2DM patients: fibrosis-4 (FIB-4), vibration-controlled transient elastography (VCTE), FIB-4 and VCTE (simultaneous), and FIB-4 and VCTE (sequential). Sensitivity analyses and price threshold analyses were performed to assess parameter uncertainties in the results.
RESULTS:
VCTE was the most cost-effective NAFLD screening strategy (USD24,727/quality-adjusted life year [QALY]), followed by FIB-4 (USD36,800/QALY), when compared to no screening. Probabilistic sensitivity analysis revealed a higher degree of certainty for VCTE as a cost-effective strategy compared to FIB-4 (90.7% versus 73.2%). The duration of expected screening benefit is the most influential variable based on incremental cost-effectiveness ratio tornado analysis. The minimum duration of screening benefit for NAFLD screening to be cost-effective was at least 2.6 years. The annual cost of NAFLD treatment should be less than USD751 for NAFLD screening to be cost-effective.
CONCLUSION
Both VCTE and FIB-4 are cost-effective NAFLD screening strategies among T2DM patients in Singapore. However, given the lack of access to VCTE at primacy care and potential budget constraints, FIB-4 can also be considered for NAFLD screening among T2DM patients in Singapore.

INTRODUCTION:
Physical activity (PA) and sedentary behaviour (SB) independently influence the health outcomes of older adults. Both provide interventional opportunities for successful ageing. We aimed to determine levels of PA and SB in ambulatory older adults and their associated factors in a developed Asian population known for its longevity.
METHODS:
We conducted a cross-sectional observational study in a Singapore public primary healthcare centre. Multi-ethnic Asian adults aged ≥ 60 years took an interviewer-administered questionnaire survey. PA and SB were assessed using the Physical Activity Scale for the Elderly (PASE; score range 0 to > 400) and the Sedentary Behaviour Questionnaire for the Elderly, respectively.
RESULTS:
Among 397 participants (50.9% female; 73.2% Chinese; 47.9% aged ≥ 70 years; 33.5% employed, including voluntary work), 58.7% had ≥ 3 chronic illnesses and 11.1% required walking aids. The median PASE score was 110.8 (interquartile range 73.8-171.6) and decreased significantly with increasing age. Higher PASE score was associated with higher educational level, employment, independent ambulation without aid, and fewer chronic illnesses (p < 0.01). Employment status significantly influenced PASE score (β = 84.9, 95% confidence interval [CI] 66.5-103.4; p < 0.01). 37.0% spent ≥ 8 hours daily on sedentary activity and were twice as likely to do so if they were employed (odds ratio 2.19, 95% CI 1.34-3.59; p < 0.01).
CONCLUSION
The PA of the older adults decreased with increasing age and increased with employment. One-third of them were sedentary for ≥ 8 hours daily. Those who were employed were twice as likely to have SB.

Introduction: Achieving optimal glycated hemoglobin (HbA1c), blood pressure (BP), and LDLCholesterol (LDL-C) in patients mitigates macro- and micro-vascular complications, which is the
key treatment goal in managing type 2 diabetes mellitus (T2DM). This study aimed to determine
the proportion of patients in an urban community with T2DM and the above modifiable
conditions attaining triple vascular treatment goals based on current practice guidelines.
Methods: A questionnaire was distributed to adult Asian patients with dyslipidemia at two primary
care clinics (polyclinics) in northeastern Singapore. The demographic and clinical data for this
sub-population with both T2DM and dyslipidemia were collated with laboratory and treatment
information retrieved from their electronic health records. The combined data was then analyzed
to determine the proportion of patients who attained triple treatment goals, and logistic regression
analysis was used to identify factors associated with this outcome.
Results: 665 eligible patients [60.5% female, 30.5% Chinese, 35% Malays, and 34.4% Indians]
with a mean age of 60.6 years were recruited. Of these patients, 71% achieved LDL-C ≤2.6
mmol/L, 70.4% had BP <140/90 mmHg, and 40.9% attained HbA1c ≤7%. Overall, 22%
achieved the triple treatment goals for glycemia, BP, and LDL-C control. The major determinants
were the number of diabetic medications and intensity of statin therapy.
Conclusion: Eight in ten patients with T2DM failed to achieve concurrent glycemic, BP, and
LDL-C treatment goals, subjecting them to risks of vascular complications. Primary healthcare
professionals can mitigate these risks by optimizing therapeutic treatment to maximize glycemia,
dyslipidemia, and BP control.

INTRODUCTIONIt is uncommon for medical students to deliver public health talks as part of their medical education curriculum. This study evaluated the effectiveness of a novel training programme that required medical students to deliver public health talks during their family medicine (FM) clerkship in a Singapore primary care institution.
METHODSThe FM faculty staff guided teams of third-year medical students to select appropriate topics for health talks that were to be conducted at designated polyclinics. The talks were video-recorded and appraised for clarity, content and delivery. The appraisal was done by the student's peers and assigned faculty staff. The audience was surveyed to determine their satisfaction level and understanding of the talks. The students also self-rated the effectiveness of this new teaching activity.
RESULTSA total of 120 medical students completed a questionnaire to rate the effectiveness of the new teaching activity. 85.8% of the students felt confident about the delivery of their talks, 95.8% reported having learnt how to deliver talks and 92.5% perceived this new training modality as useful in their medical education. Based on the results of the audience survey, the speakers were perceived as knowledgeable (53.1%), confident (51.3%) and professional (39.0%). Assessment of 15 video-recorded talks showed satisfactory delivery of the talks by the students.
CONCLUSIONThe majority of the students reported a favourable overall learning experience under this new training programme. This finding is supported by the positive feedback garnered from the audience, peers of the medical students and the faculty staff.

INTRODUCTIONThe prevalence of orthostatic hypotension (OH) among the elderly population in Singapore, as defined by a decline in blood pressure upon a change in position, is not well-established. Studies associate OH with clinically significant outcomes such as falls. This study aims to determine the prevalence of OH among elderly patients attending a public primary care clinic (polyclinic) for chronic disease management, and examine the relationships between postulated risk factors and OH.
METHODSPatients aged ≥ 65 years attending a typical polyclinic in Geylang were identified and targeted for recruitment at the study site. A questionnaire on symptoms and postulated risk factors was administered, followed by supine and standing blood pressure measurements. Cross-sectional analysis was performed with independent sample t-test for continuous data and chi-square test for categorical data. Prevalence rate ratios with 95% confidence interval were calculated for the latter.
RESULTSA total of 364 multiethnic patients participated in the study. The prevalence of OH was 11.0%. Older age, comorbidities such as cardiac failure and kidney disease, being physically inactive at work, fatigue, self-reported dizziness in the past year, and the use of loop diuretics were found to be significantly associated with OH.
CONCLUSIONAbout one in ten elderly patients at a local polyclinic was affected by OH, which was associated with multiple factors. Some of these factors are modifiable and can be addressed to reduce the incidence of OH.

INTRODUCTIONDyslipidaemia leads to atherosclerosis and is a major risk factor for cardiovascular diseases. In clinical trials, 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, or statins, have been shown to effectively reduce dyslipidaemia. Despite the availability and accessibility of statins, myocardial infarctions and cerebrovascular accidents remain among the top causes of mortality in developed countries, including Singapore. This enigma could be attributed to suboptimal adherence to statin therapy. The present literature review aimed to evaluate patients' perceptions of statin therapy.
METHODSWe searched PubMed and other databases for articles published in English from October 1991 to May 2012 containing keywords such as 'patient', 'views', 'perceptions', 'adherence', 'statin' and 'dyslipidaemia'. Of the 122 eligible studies retrieved, 58 were reviewed. The findings were categorised and framed in accordance with the Health Belief Model.
RESULTSPatients with dyslipidaemia appeared to underestimate their susceptibility to dyslipidaemia-related complications, partly due to their demographic profiles. Failure to appreciate the severity of potential complications was a major hindrance toward adherence to statin therapy. Other factors that affected a patient's adherence included lack of perceived benefits, perceived side effects, the cost of statins, poor physician-patient relationship, and overestimation of the effectiveness of diet control as a treatment modality.
CONCLUSIONExisting evidence suggests that the cause of poor adherence to statin therapy is multifactorial. The use of the Health Belief Model to present the results of our literature review provides a systematic framework that could be used to design a patient-centric approach for enhancing adherence to statin therapy.

INTRODUCTIONAcute respiratory infections are prevalent and pose a constant threat to society. While the use of facemasks has proven to be an effective barrier to curb the aerosol spread of such diseases, its use in the local community is uncommon, resulting in doubts being cast on its effectiveness in preventing airborne infections during epidemics. We thus aimed to conduct a literature review to determine the factors that influence the use of facemasks as a primary preventive health measure in the community.
METHODSA search for publications relating to facemask usage was performed on Medline, PubMed, Google, World Health Organization and Singapore government agencies' websites, using search terms such as 'facemask', 'mask', 'influenza', 'respiratory infection', 'personal protective equipment', 'disease prevention', 'compliance' and 'adherence'. Findings were framed under five components of the Health Belief Model: perceived susceptibility, perceived benefits, perceived severity, perceived barriers and cues to action.
RESULTSWe found that individuals are more likely to wear facemasks due to the perceived susceptibility and perceived severity of being afflicted with life-threatening diseases. Although perceived susceptibility appeared to be the most significant factor determining compliance, perceived benefits of mask-wearing was found to have significant effects on mask-wearing compliance as well. Perceived barriers include experience or perception of personal discomfort and sense of embarrassment. Media blitz and public health promotion activities supported by government agencies provide cues to increase the public's usage of facemasks.
CONCLUSIONComplex interventions that use multipronged approaches targeting the five components of the Health Belief Model, especially perceived susceptibility, are needed to increase the use of facemasks in the community. Further studies are required to evaluate the effectiveness of implemented interventions.
