INTRODUCTIONThe journal impact factor is often used to judge the scientific quality of individual research articles and individual journals. Despite numerous reviews in the literature criticising such use, in some countries the impact factor has become an outcome measure for grant applications, job applications, promotions and bonuses. The aim of this review is to highlight the major issues involved with using the journal impact factor as a measure of research quality.
METHODSA literature review of articles on journal impact factors, science citation index, and bibliometric methods was undertaken to identify relevant articles.
RESULTSThe journal impact factor is a quantitative measure based on the ratio between yearly citations in a particular journal to total citations in that journal in the previous 2 years. Its use as a criterion for measuring the quality of research is biased. The major sources of bias include database problems from the Institute for Scientific Information and research field effects. The journal impact factor, originally designed for purposes other than the individual evaluation of research quality, is a useful tool provided its interpretation is not extrapolated beyond its limits of validity.
CONCLUSIONResearch quality cannot be measured solely using the journal impact factor. The journal impact factor should be used with caution, and should not be the dominant or only factor determining research quality.

Ensuring timely access to specialist care is an important indicator of the quality of a health service. Demand for cardiology outpatient appointments has grown considerably in the last decade, leading to increased waiting time for cardiology appointments at public hospitals. This paper examines the effectiveness of past and ongoing strategies initiated by the National Heart Centre, many of which were in collaboration with SingHealth Polyclinics, documents the lessons learnt, and provides a framework for approaching this problem. Instead of a simplistic approach where institutions react to long waiting times by growing capacity to meet demand, this paper emphasises the need to focus on the final intended outcome (timely diagnosis and treatment) rather than on a single performance indicator, such as waiting time. A broad systems approach at the national level is advocated, rather than piecemeal, uncoordinated actions by individual hospitals.

Alleviation of suffering in palliative care needs a combination of good symptom control and psychosocial care. The capacity of mindfulness to promote psychological flexibility opens up possibilities of creating a paradigm shift that can potentially change the landscape of psychosocial care. In this review, we attempt to introduce 4 methods to establish mindfulness based on 'The Discourse on the Foundations of Mindfulness', a core text of Theravada Buddhism, followed by a brief comparison of the concepts and practices of mindfulness in different cultures and religions in Southeast Asia. Next, 2 mindfulness-based interventions specifically designed for palliative psychosocial care - mindfulness-based supportive therapy (MBST) and mini-mindfulness meditation (MMM) are introduced. We hypothesise that mindful practices, tailored to the palliative setting, can promote positive psychosocial outcomes.

INTRODUCTIONWhether fi nal height is associated with quality of life and mental health is a matter of epidemiological and medical concern. Both social and biological explanations have been previously proposed. This study aims to assess the associations in ethnic Chinese in Singapore.
MATERIALS AND METHODSA cross-sectional study of 4414 respondents aged at least 21 years seen at a major polyclinic was performed. Socioeconomic and behavioural features of the sample and the Singapore population of similar ages were comparable. Height was measured by clinic nurses using an ultrasonic height senor. Participants were interviewed for socioeconomic, behavioural, health and quality of life information. Clinical morbidity data was collected from the participants' treating physicians. The SF-6D utility index and its Mental Health domain were the main endpoints. Linear and ordinal logistic regression models were used to analyse the utility index and the Mental Health scores, respectively.
RESULTSHaving adjusted for age and gender, the Mental Health domain (P <0.01) was associated with height but the utility index was not. Further adjustment for health, socioeconomic and behavioural covariates made little difference. Analyses based on height categories showed similar trends.
CONCLUSIONAdult height has a positive association with mental health as measured by the SF-6D among ethnic Chinese in Singapore. Socioeconomic status and known physical health problems do not explain this association. Adult height had no association with SF-6D utility index scores.

INTRODUCTIONWhile opioids are effective in carefully selected patients with chronic non-cancer pain (CNCP), they are associated with potential risks. Therefore, treatment recommendations for the safe and effective use of opioids in this patient population are needed.
MATERIALS AND METHODSA multidisciplinary expert panel was convened by the Pain Association of Singapore to develop practical evidence-based recommendations on the use of opioids in the management of CNCP in the local population. This article discusses specific recommendations for various common CNCP conditions.
RESULTSAvailable data demonstrate weak evidence for the long-term use of opioids. There is moderate evidence for the short-term benefit of opioids in certain CNCP conditions. Patients should be carefully screened and assessed prior to starting opioids. An opioid treatment agreement must be established, and urine drug testing may form part of this agreement. A trial duration of up to 2 months is necessary to determine efficacy, not only in terms of pain relief, but also to document improvement in function and quality of life. Regular reviews are essential with appropriate dose adjustments, if necessary, and routine assessment of analgesic efficacy, aberrant behaviour and adverse effects. The reasons for discontinuation of opioid therapy include side effects, lack of efficacy and aberrant drug behaviour.
CONCLUSIONDue to insufficient evidence, the task force does not recommend the use of opioids as first-line treatment for various CNCP. They can be used as secondor third-line treatment, preferably as part of a multimodal approach. Additional studies conducted over extended periods are required.

Objectives:
Type 2 diabetes mellitus (T2DM) shares a complex relationship with bone metabolism and few studies investigated the effect of impaired bone health on the risk of T2DM. This study was conducted to investigate the association between hip fractures and the risk of incident T2DM.
Methods:
This is a retrospective cohort study using data from the real-world hip fracture cohort. Hong Kong Chinese patients aged ≥ 65 years without T2DM who were admitted to public hospitals due to a fall between 2008 and 2015 were included in the study. Patients who sustained falls with and without hip fractures were matched by propensity score (PS) at a 1:1 ratio. Competing risk regression was used to evaluate the association between hip fracture and incident T2DM, with death being the competing event.
Results:
A total of 23,314 hip fracture cases were matched to 23,314 controls. The median follow-up time was 5.09 years. The incidence rate of T2DM was 11.947 and 14.505 per 1000 person-years for the hip fracture and control group respectively. After accounting for the competing risk of death, the hip fracture group had a significantly lower risk of developing T2DM (HR: 0.771, 95% CI: 0.719–0.827). Similar results were observed in all subgroups after stratification by age and sex.
Conclusions
Hip fracture was found to be associated with a reduced risk of T2DM. These findings provide insight into the topic of bone and glucose metabolism and prompt further research in evaluating the role of bone health in the management of T2DM.

INTRODUCTION:
Dyslipidaemia is a major risk factor for coronary heart disease (CHD). There is a lack of data on the extent of lipid abnormalities and lipid-lowering therapy (LLT) in Singapore.
METHODS:
The Dyslipidemia International Study (DYSIS) II was a multinational observational study of patients with stable CHD and hospitalised patients with an acute coronary syndrome (ACS). A full lipid profile and use of LLT were documented at baseline, and for the ACS cohort, at four months post-hospitalisation.
RESULTS:
325 patients were recruited from four sites in Singapore; 199 had stable CHD and 126 were hospitalised with an ACS. At baseline, 96.5% of the CHD cohort and 66.4% of the ACS cohort were being treated with LLT. In both cohorts, low-density lipoprotein cholesterol (LDL-C) levels were lower for the treated than the non-treated patients; accordingly, a higher proportion of patients met the LDL-C goal of < 70 mg/dL (CHD: 28.1% vs. 0%, p = 0.10; ACS: 20.2% vs. 0%, p < 0.01). By the four-month follow-up, a higher proportion of the ACS patients that were originally not treated with LLT had met the LDL-C goal (from 0% to 54.5%), correlating with the increased use of medication. However, there was negligible improvement in the patients who were treated prior to the ACS.
CONCLUSION
Dyslipidaemia is a significant concern in Singapore, with few patients with stable or acute CHD meeting the recommended European Society of Cardiology/European Atherosclerosis Society goal. LLT was widely used but not optimised, indicating considerable scope for improved management of these very-high-risk patients.
