Abstract
BACKGROUND/INTRODUCTION Cardio-cerebral infarction (CCI), which involves the simultaneous occurrence of acute ischaemic stroke and acute myocardial infarction, has a reported incidence of 0.0009%. Treatment of CCI presents a dilemma to physicians as both conditions are time critical. Despite the need for standardized treatment protocols, published data are sparse. AIM We aimed to summarize the reported cardio-cerebral infarction cases in the literature. DESIGN Meta-analysis. METHODS Four databases, Pubmed, Embase, Scopus and Google Scholar were searched until 25 August 2020. A title and abstract sieve, full-text review and extraction of data were conducted independently by three authors. RESULTS A total of 44 cases of CCI were identified from 37 case reports and series; 15 patients (34.1%) were treated using percutaneous coronary intervention (PCI) with stent, 8 patients (18.2%) were treated with a PCI without stent, 10 patients (22.7%) were treated via a cerebral vessel thrombectomy and 8 patients (18.2%) were treated via a thrombectomy of a coronary vessel. For medications, 20 patients (45.5%) were treated with thrombolytics, 10 patients (22.7%) were treated with anticoagulants, 8 patients (18.2%) were treated with antiplatelets and 11 patients (25.0%) were treated with anticoagulants and antiplatelets. Of 44 patients, 10 patients died, and 9 of those were due to cardiac causes. Among the 44 patients, days to death was observed to be a median of 2.0 days (interquartile range (IQR): 1.5, 4.0). The modified Rankin Score was measured in nine patients, with a median score of 2.0 (IQR: 1.0, 2.5) being reported. DISCUSSION/CONCLUSION The condition of CCI has substantial morbidity and mortality, and further studies are needed to examine the optimal diagnostic and treatment strategies of these patients.

Abstract
Aims To define plasma concentrations, determinants, and optimal prognostic cut‐offs of soluble suppression of tumorigenesis‐2 (sST2), high‐sensitivity cardiac troponin T (hs‐cTnT), and N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) in women and men with chronic heart failure (HF). Methods and results Individual data of patients from the Biomarkers In Heart Failure Outpatient Study (BIOS) Consortium with sST2, hs‐cTnT, and NT‐proBNP measured were analysed. The primary endpoint was a composite of 1 year cardiovascular death and HF hospitalization. The secondary endpoints were 5 year cardiovascular and all‐cause death. The cohort included 4540 patients (age 67 ± 12 years, left ventricular ejection fraction 33 ± 13%, 1111 women, 25%). Women showed lower sST2 (24 vs. 27 ng/mL, P < 0.001) and hs‐cTnT level (15 vs. 20 ng/L, P < 0.001), and similar concentrations of NT‐proBNP (1540 vs. 1505 ng/L, P = 0.408). Although the three biomarkers were confirmed as independent predictors of outcome in both sexes, the optimal prognostic cut‐off was lower in women for sST2 (28 vs. 31 ng/mL) and hs‐cTnT (22 vs. 25 ng/L), while NT‐proBNP cut‐off was higher in women (2339 ng/L vs. 2145 ng/L). The use of sex‐specific cut‐offs improved risk prediction compared with the use of previously standardized prognostic cut‐offs and allowed to reclassify the risk of many patients, to a greater extent in women than men, and for hs‐cTnT than sST2 or NT‐proBNP. Specifically, up to 18% men and up to 57% women were reclassified, by using the sex‐specific cut‐off of hs‐cTnT for the endpoint of 5 year cardiovascular death. Conclusions In patients with chronic HF, concentrations of sST2 and hs‐cTnT, but not of NT‐proBNP, are lower in women. Lower sST2 and hs‐cTnT and higher NT‐proBNP cut‐offs for risk stratification could be used in women.

Abstract
AIMS Chronic obstructive pulmonary disease (COPD) is a frequent comorbidity in patients with heart failure (HF). We assessed the influence of COPD on circulating levels and prognostic value of three HF biomarkers: N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity troponin T (hs-TnT), and soluble suppression of tumorigenesis-2 (sST2). METHODS Individual data from patients with chronic HF, known COPD status, NT-proBNP and hs-TnT values (n = 8088) were analysed. A subgroup (n = 3414) had also sST2 values. RESULTS Patients had a median age of 66 years (interquartile interval 57-74), 77% were men and 82% had HF with reduced ejection fraction. NT-proBNP, hs-TnT and sST2 were 1207 ng/l (487-2725), 17 ng/l (9-31) and 30 ng/ml (22-44), respectively. Patients with COPD (n = 1249, 15%) had higher NT-proBNP (P = 0.042) and hs-TnT (P < 0.001), but not sST2 (P = 0.165). Over a median 2.0-year follow-up (1.5-2.5), 1717 patients (21%) died, and 1298 (16%) died from cardiovascular causes; 2255 patients (28%) were hospitalized for HF over 1.8 years (0.9-2.1). NT-proBNP, hs-TnT and sST2 predicted the three end points regardless of COPD status. The best cut-offs from receiver-operating characteristics analysis were higher in patients with COPD than in those without. Patients with all three biomarkers higher than or equal to end-point- and COPD-status-specific cut-offs were also those with the worst prognosis. CONCLUSIONS Among patients with HF, those with COPD have higher NT-proBNP and hs-TnT, but not sST2. All these biomarkers yield prognostic significance regardless of the COPD status.

Abstract
Abstract
Aims
Limited evidence exists on sex-related differences in clinical value of biomarkers in chronic heart failure (HF). We aimed to define plasma levels, determinants, and optimal prognostic cut-offs of soluble suppression of tumourigenesis-2 (sST2), high-sensitivity troponin T (hs-TnT), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in female and male chronic HF patients.
Methods and results
Individual data of patients from the BIOS (Biomarkers In Heart Failure Outpatient Study) Consortium with sST2, hs-TnT, and NT-proBNP measured were analysed. The primary endpoint was a composite of 1-year cardiovascular death and HF hospitalization. The secondary endpoints were 5-year cardiovascular and all-cause death. The cohort included 4540 patients (age: 67 ± 12 years, LVEF 33 ± 13%, 1111 women, 25%). Women showed lower sST2 (24 vs. 27 ng/ml, P < 0.001) and hs-TnT level (15 vs. 20 ng/l, P < 0.001), and similar concentrations of NT-proBNP (1540 vs. 1505 ng/l, P = 0.408). Although the three biomarkers were confirmed as independent predictors of outcome in both sexes, the optimal prognostic cut-off was lower in women for sST2 (28 vs. 31 ng/ml) and hs-TnT (22 vs. 25 ng/l), while NT-proBNP cut-off was higher in women (2339 ng/l vs. 2145 ng/l). The use of sex-specific cut-offs improved risk prediction compared to the use of previously standardized prognostic cut-offs (Figure).
Conclusions
In patients with chronic HF, levels of sST2 and hs-TnT, but not of NT-proBNP are lower in women. Lower sST2 and hs-TnT and higher NT-proBNP cut-offs for risk stratification could be used in women.

Abstract
Aims The importance of iron deficiency (ID) in heart failure with preserved ejection fraction (HFpEF) is unknown. In HF with reduced ejection fraction (HFrEF), ID is reported as an independent predictor of mortality in HF although not all published studies agree. Different definitions of ID have been assessed, and the natural history of untreated ID not established, which may explain the conflicting results. This study aimed to assess the relationship between ID and mortality in HFpEF, clarify which definition of ID correlates best with outcomes in HFrEF, and determine the prognostic importance of change in ID status over time. Methods and results Analyses were conducted on data from 1563 patients participating in a prospective international cohort study comparing HFpEF with HFrEF. Plasma samples from baseline and 6 month visits were analysed for the presence of ID. Two ID definitions were evaluated: IDFerritin = ‘ferritin < 100 mcg/L or ferritin 100–300 mcg/L + transferrin saturation < 20%’ and IDTsat = ‘transferrin saturation < 20%’. The risk of all‐cause mortality and death/HF hospitalization associated with baseline ID (IDFerritin or IDTsat) and change in ID status at 6 months (persistent, resolving, developing, or never present) was estimated in multivariable Cox proportional hazards models. Of 1563 patients, 1115 (71%) had HFrEF and 448 (29%) HFpEF. Prevalence of ID was similar in HFpEF and HFrEF (58%). Patients with ID were more likely to be female, diabetic, and have a higher co‐morbid burden than patients without ID. ID by either definition did not confer independent risk for either all‐cause mortality or death/HF hospitalization for patients with HFpEF [IDFerritin hazard ratio (HR) 0.65 (95% confidence interval 0.40–1.05), P = 0.08; IDTsat HR 1.16 (0.72–1.87), P = 0.55]. In the overall study cohort (HFrEF + HFpEF) and HFrEF subgroup, IDFerritin was inferior to IDTsat in prediction of all‐cause mortality [overall cohort: HR 1.21 (0.95–1.53), P = 0.12 vs. HR 1.95 (1.52–2.51), P < 0.01; HFrEF: HR 1.12 (0.85–1.48), P = 0.43 vs. HR 1.57 (1.15–2.14), P < 0.01]. Persistence of IDTsat at 6 months was strongly associated with poor outcomes compared with never having IDTsat [HR 2.22 (1.42–3.46), P < 0.01] or having IDTsat at baseline self‐resolve by 6 months [HR 1.40 (1.06–1.86), P = 0.02]. Conclusions Iron deficiency is equally prevalent in HFpEF and HFrEF but is negatively prognostic only in HFrEF. The natural history of ID is important; persistent ID is strongly associated with mortality whereas resolution is not. IDTsat is the superior definition of ID and should inform future trials investigating the efficacy of intravenous iron replacement in patients with HFrEF.

Abstract
OBJECTIVES The goal of this study was to assess the predictive power of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and the decision cutoffs in heart failure (HF) across body mass index (BMI) categories. BACKGROUND Concentrations of NT-proBNP predict outcome in HF. Although the influence of BMI to reduce levels of NT-proBNP is known, the impact of obesity on prognostic value remains uncertain. METHODS Individual data from the BIOS (Biomarkers In Heart Failure Outpatient Study) consortium were analyzed. Patients with stable HF were classified as underweight (BMI <18.5 kg/m2), normal weight (BMI 18.5-24.9 kg/m2), overweight (BMI 25-29.9 kg/m2), and mildly (BMI 30-34.9 kg/m2), moderately (BMI 35-39.9 kg/m2), or severely (BMI ≥40 kg/m2) obese. The prognostic role of NT-proBNP was tested for the endpoints of all-cause and cardiac death. RESULTS The study population included 12,763 patients (mean age 66 ± 12 years; 25% women; mean left ventricular ejection fraction 33% ± 13%). Most patients were overweight (n = 5,176), followed by normal weight (n = 4,299), mildly obese (n = 2,157), moderately obese (n = 612), severely obese (n = 314), and underweight (n = 205). NT-proBNP inversely correlated with BMI (β = -0.174 for 1 kg/m2; P < 0.001). Adding NT-proBNP to clinical models improved risk prediction across BMI categories, with the exception of severely obese patients. The best cutoffs of NT-proBNP for 5-year all-cause death prediction were lower as BMI increased (3,785 ng/L, 2,193 ng/L, 1,554 ng/L, 1,045 ng/L, 755 ng/L, and 879 ng/L, for underweight, normal weight, overweight, and mildly, moderately, and severely obese patients, respectively) and were higher in women than in men. CONCLUSIONS NT-proBNP maintains its independent prognostic value up to 40 kg/m2 BMI, and lower optimal risk-prediction cutoffs are observed in overweight and obese patients.

Abstract
OBJECTIVES Due to the lack of a uniform obesity definition, there is marked variability in reported sarcopenic obesity (SO) prevalence and associated health outcomes. We compare the association of SO with physical function using current Asian Working Group for Sarcopenia (AWGS) guidelines and different obesity measures to propose the most optimal SO diagnostic formulation according to functional impairment, and describe SO prevalence among community-dwelling young and old adults. DESIGN Obesity was defined according to waist circumference (WC), percentage body fat (PBF), fat mass index (FMI), fat mass/fat-free mass ratio (FM/FFM), or body mass index (BMI). SO was defined as the presence of both obesity and AWGS sarcopenia. Muscle function was compared among phenotypes and obesity definitions using ANOVA. Differences across obesity measures were further ascertained using multiple linear regressions to determine their associations with the Short Physical Performance Battery (SPPB). SETTING Community-dwelling adults 21 years old and above were recruited from a large urban residential town in Singapore. PARTICIPANTS 535 community-dwelling Singaporeans were recruited (21-90 years old, 57.9% women), filling quotas of 20-40 participants in each sex- and age-group. MEASUREMENTS We took measurements of height, weight, BMI, waist and hip circumferences, body fat, muscle mass, muscle strength, and functional assessments. Questionnaire-based physical and cognitive factors were also assessed. RESULTS Overall prevalence of SO was 7.6% (WC-based), 5.1% (PBF-based), 2.7% (FMI-based), 1.5% (FM/FFM-based), and 0.4% (BMI-based). SO was significantly associated with SPPB only in the FMI model (p<0.05), and total variance explained by the different regression models was highest for the FMI model. CONCLUSIONS Our findings suggest FMI as the most preferred measure for obesity and support its use as a diagnostic criteria for SO.

Abstract
OBJECTIVES To determine the overlapping prevalence of malnutrition and sarcopenia and the association between parameters of malnutrition with muscle mass and strength in a community-dwelling Singaporean adult population. DESIGN This was a cross-sectional study. SETTING Large north-eastern residential town of Yishun in Singapore. PARTICIPANTS Random sampling of community-dwelling Singaporeans aged 21-90 years old (n=541). MEASUREMENTS Anthropometry, body composition and handgrip strength (muscle strength) were measured. Sarcopenia was identified using dual-energy x-ray absorptiometry scan (muscle mass). Nutritional status was measured using Mini Nutritional Assessment (MNA-SF). Other questionnaires collected included physical activity and cognition. Associations between nutritional status with sarcopenia as well as with muscle mass and strength were analysed using multinomial logistics and linear regressions. RESULTS The overall population-adjusted prevalence of those at nutritional risk and malnourished were 18.5% and 0.1% respectively. More than a third of participants (35%) who were at nutritional risk were sarcopenic. Malnourished participants were all sarcopenic (100%, N=2) whereas those who were sarcopenic, 27.0% (N=37) were at nutritional risk/malnourished. Being at nutritional risk/malnourished was significantly associated with 2 to 3 times increased odds of sarcopenia in multivariate analyses adjusting for age, gender, physical activity level and cognition, and fat mass index. Favourable MNA parameter scores on food intake and BMI were positively associated with greater muscle mass and handgrip strength (p<0.05). CONCLUSION Given the overlapping clinical presentation of malnutrition and sarcopenia, community screening protocols should include combination screening of nutritional status and sarcopenia with appropriate interventions to mitigate risk of adverse health outcomes.

Abstract
OBJECTIVES Experimental evidence suggest that tea polyphenols have anti-depressant effect and tea consumption may reduce the risk and severity of depression. We investigated whether tea consumption was associated with changes in depressive symptoms over time among Asian older adults. DESIGN Population-based prospective cohort study with mean 4 years of follow up. SETTING Singapore Longitudinal Ageing Study (SLAS) of community-living older persons. PARTICIPANTS 3177 participants overall (mean age 67 years) and 3004 participants who were depression-free at baseline. MEASUREMENTS Baseline tea consumption which include Chinese (black, oolong or green) tea or Western (mixed with milk) tea and change in Geriatric Depression Scale (GDS) measure of depression. Incident depression was defined by GDS≥5, and GDS depression improvement or deterioration by GDS change of ≥4 points. Estimated odds ratio and 95% confidence intervals (OR, 95%CI) were adjusted for baseline age, sex, ethnicity, education, housing type, single/divorced/widowed, living alone, physical and social activity, smoking, alcohol, number of comorbidities, MMSE, and baseline GDS level. RESULTS Compared to non-tea drinkers, participants who consumed ≥3 cups of tea of all kinds were significantly less likely to have worsened GDS symptoms: OR=0.32, 95% CI=0.12, 0.84. Among baseline depression-free participants, the risk of incident GDS (≥5) depression was significantly lower (OR=0.34, 95%CI=0.13, 0.90) for daily consumption of all types of tea, and Chinese (black, oolong or green) tea (OR=0.46, 95%CI=0.21,0.99). CONCLUSION This study suggests that tea may prevent the worsening of existing depressive symptoms and the reduce the likelihood of developing threshold depression.

Abstract
BACKGROUND Studies suggest that nutritional interventions using the whole diet approach such as the Mediterranean diet may delay cognitive decline and dementia onset. However, substantial numbers of older adults are non-adherent to any ideally healthy dietary pattern and are at risk of malnutrition. OBJECTIVE The present study investigated the relationship between global malnutrition risk and onsets of cognitive decline and neurocognitive disorders (NCD), including mild cognitive impairment (MCI) or dementia in community-dwelling older adults. METHODS Participants aged ≥ 55 years in the Singapore Longitudinal Ageing Studies (SLAS) were assessed at baseline using the Elderly Nutritional Indicators for Geriatric Malnutrition Assessment (ENIGMA) and followed up 3-5 years subsequently on cognitive decline (MMSE drop ≥ 2) among 3128 dementia-free individuals, and incident neurocognitive disorders (NCD) among 2640 cognitive normal individuals. RESULTS Individuals at high nutritional risk score (≥ 3) were more likely to develop cognitive decline (OR=1.42, 95%CI=1.01-1.99) and incident MCI-or-dementia (OR=1.64, 95%CI=1.03-2.59), controlling for age, sex, ethnicity, low education, APOE-e4, hearing loss, physical, social, and mental activities, depressive symptoms, smoking, alcohol, central obesity, hypertension, diabetes, low HDL, high triglyceride, cardiac disease, and stroke. Among ENIGMA component indicators, low albumin at baseline was associated with cognitive decline and incident NCD, and 5 or more drugs used, few fruits/vegetables/milk products daily, and low total cholesterol were associated with incident NCD. CONCLUSION The ENIGMA measure of global malnutrition risk predicts cognitive decline and incident neurocognitive disorders, suggesting the feasibility of identifying vulnerable subpopulations of older adults for correction of malnutrition risk to prevent neurocognitive disorders.

Abstract
BACKGROUND Mild cognitive impairment (MCI) is a critical pre-dementia target for preventive interventions. There are few brief screening tools based on self-reported personal lifestyle and health-related information for predicting MCI that have been validated for their generalizability and utility in primary care and community settings. OBJECTIVE To develop and validate a MCI risk prediction index, and evaluate its field application in a pilot community intervention trial project. DESIGN Two independent population-based cohorts in the Singapore Longitudinal Ageing Study (SLAS). We used SLAS1 as a development cohort to construct the risk assessment instrument, and SLA2 as a validation cohort to verify its generalizability. SETTING community-based screening and lifestyle intervention Participants: (1) SLAS1 cognitively normal (CN) aged ≥55 years with average 3 years (N=1601); (2) SLAS2 cohort (N=3051) with average 4 years of follow up. (3) 437 participants in a pilot community intervention project. MEASUREMENTS The risk index indicators included age, female sex, years of schooling, hearing loss, depression, life satisfaction, number of cardio-metabolic risk factors (wide waist circumference, pre-diabetes or diabetes, hypertension, dyslipidemia). Weighted summed scores predicted probabilities of MCI or dementia. A self-administered questionnaire field version of the risk index was deployed in the pilot community project and evaluated using pre-intervention baseline cognitive function of participants. RESULTS Risk scores were associated with increasing probabilities of progression to MCI-or-dementia in the development cohort (AUC=0.73) and with increased prevalence and incidence of MCI-or-dementia in the validation cohort (AUC=0.74). The field questionnaire risk index identified high risk individuals with strong correlation with RBANS cognitive scores in the community program (p<0.001). CONCLUSIONS The SLAS risk index is accurate and replicable in predicting MCI, and is applicable in community interventions for dementia prevention.

Abstract
OBJECTIVES To investigate risk factors of incident physical frailty. DESIGN A population-based observational longitudinal study. SETTING Community-dwelling elderly with age 55 years and above recruited from 2009 through 2011 in the second wave Singapore Longitudinal Ageing Study-2 (SLAS-2) were followed up 3-5 years later. PARTICIPANTS A total of 1297 participants, mean age of 65.6 ±0.19, who were free of physical frailty. MEASUREMENTS Incident frailty defined by three or more criteria of the physical phenotype used in the Cardiovascular Health Study was determined at follow-up. Potential risk factors assessed at baseline included demographic, socioeconomic, medical, psychological factors, and biochemical markers. RESULTS A total of 204 (15.7%) participants, including 81 (10.87%) of the robust and 123 (22.28%) of the prefrail transited to frailty at follow-up. Age, no education, MMSE score, diabetes, prediabetes and diabetes, arthritis, ≥5 medications, fair and poor self-rated health, moderate to high nutritional risk (NSI ≥3), Hb (g/dL), CRP (mg/L), low B12, low folate, albumin (g/L), low total cholesterol, adjusted for sex, age and education, were significantly associated (p<0.05) with incident frailty. In stepwise selection models, age (year) (OR=1.07, 95%CI=1.03-1.10, p<0.001), albumin (g/L) (OR=0.85, 95%CI=0.77-0.94, p=0.002), MMSE score (OR=0.88, 95%CI=0.78-0.98, p=0.02), low folate (OR=3.72, 95%CI=1.17-11.86, p=0.03, and previous hospitalization (OR=2.26, 95%CI=1.01-5.04,p=0.05) were significantly associated with incident frailty. CONCLUSIONS The study revealed multiple modifiable risk factors, especially related to poor nutrition, for which preventive measures and early management could potentially halt or delay the development of frailty.

Abstract
BACKGROUND Physical frailty is well known to be strongly associated with malnutrition, but the combined impact of physical frailty and cognitive impairment among non-demented older persons (cognitive frailty) on malnutrition prevalence is not well documented. DESIGN Cross-sectional cohort study. SETTING AND PARTICIPANTS Community-dwelling older Singaporeans aged ≥55y (n=5414) without dementia in the Singapore Longitudinal Ageing Study (SLAS-1 and SLAS-2). MEASUREMENTS The Mini Nutritional Assessment - short form (MNA-SF) and Nutrition Screening Initiative (NSI) Determine Checklist were used to determine their nutritional status. Participants were categorized as cognitive normal (CN) or cognitive impaired (CI) by Mini Mental State Examination (MMSE<=23), as pre-frail (PF) (score=1-2) or frail (F) (score=3-5) using Fried's criteria, and as cognitive pre-frail (PF+CI) or cognitive frail (F+CI). RESULTS The prevalence of cognitive frailty was 1.6%, and cognitive pre-frailty was 5.5% (total, 7.1%). The prevalence of MNA malnutrition was 2.4%, and NSI high nutritional risk was 6.3%. The prevalence of MNA malnutrition was lowest among Robust-CN and highest among Frail-CI (0.5% in Robust-CN, 0.6% in Robust-CI, 2.8% in Pre-frail-CN, 7.3% in Pre-frail-CI, 15.4% in Frail-CN, and 23.1% in Frail-CI). Similarly, the prevalence of NSI high nutritional risk was lowest in Robust-CN (3.7%) and highest in Frail-CI (13.6%). Adjusted for sociodemographic and health status, pre-frailty/frailty-CI versus Robust-CN was associated with the highest odds ratio of association with MNA malnutrition (OR=8.16, p<0.001), although not the highest with NSI high nutritional risk (OR=1.48, p=0.017). CONCLUSIONS An extraordinary high prevalence of malnutrition was observed among older adults with cognitive frailty who should be specially targeted for active intervention.

Abstract
Aims Whether prevalence and mortality of patients with heart failure with preserved or mid-range (40-49%) ejection fraction (HFpEF and HFmREF) are similar to those of heart failure with reduced ejection fraction (HFrEF), as reported in some epidemiologic studies, remains highly controversial. We determined and compared characteristics and outcomes for patients with HFpEF, HFmREF, and HFrEF in a prospective, international, multi-ethnic population. Methods and results Prospective multi-centre longitudinal study in New Zealand (NZ) and Singapore. Patients with HF were assessed at baseline and followed over 2 years. The primary outcome was death from any cause. Secondary outcome was death and HF hospitalization. Cox proportional hazards models were used to compare outcomes for patients with HFpEF, HFmrEF, and HFrEF. Of 2039 patients enrolled, 28% had HFpEF, 13% HFmrEF, and 59% HFrEF. Compared with HFrEF, patients with HFpEF were older (62 vs. 72 years), more commonly female (17% vs. 48%), and more likely to have a history of hypertension (61% vs. 78%) but less likely to have coronary artery disease (55% vs. 41%). During 2 years of follow-up, 343 (17%) patients died. Adjusting for age, sex, and clinical risk factors, patients with HFpEF had a lower risk of death compared with those with HFrEF (hazard ratio 0.62, 95% confidence interval 0.46-0.85). Plasma (NT-proBNP) was similarly related to mortality in both HFpEF, HFmrEF, and HFrEF independent of the co-variates listed and of ejection fraction. Results were similar for the composite endpoint of death or HF and were consistent between Singapore and NZ. Conclusion These prospective multinational data showed that the prevalence of HFpEF within the HF population was lower than HFrEF. Death rate was comparable in HFpEF and HFmrEF and lower than in HFrEF. Plasma levels of NT-proBNP were independently and similarly predictive of death in the three HF phenotypes.

Abstract
Singapore is one of the fastest-aging populations due to increased life expectancy and lowered fertility. Lifestyle changes increase the burden of chronic diseases and disability. These have important implications for social protection systems. The goal of this paper is to model future functional disability and healthcare expenditures based on current trends. To project the health, disability and hospitalization spending of future elders, we adapted the Future Elderly Model (FEM) to Singapore. The FEM is a dynamic Markov microsimulation model developed in the US. Our main source of population data was the Singapore Chinese Health Study (SCHS) consisting of 63,000 respondents followed up over three waves from 1993 to 2010. The FEM model enables us to investigate the effects of disability compounded over the lifecycle and hospitalization spending, while adjusting for competing risk of multi-comorbidities. Results indicate that by 2050, 1 in 6 elders in Singapore will have at least one ADL disability and 1 in 3 elders will have at least one IADL disability, an increase from 1 in 12 elders and 1 in 5 elders respectively in 2014. The highest prevalence of functional disability will be in those aged 85 years and above. Lifetime hospitalization spending of elders aged 55 and above is US$24,400 (30.2%) higher among people with functional disability compared to those without disability. Policies that successfully tackle diabetes and promote healthy living may reduce or delay the onset of disability, leading to potential saving. In addition, further technological improvements may reduce the financial burden of disability.

Abstract
BACKGROUND Malnutrition is a major determinant of the physical frailty syndrome. Dynamic transitions in frailty states over time is well documented, but few studies have documented temporal changes in nutritional states and whether they influence frailty outcomes. DESIGN Longitudinal cohort study. SETTING AND PARTICIPANTS Community-dwelling older Singaporeans aged ≥55y with a 5-year follow-up (n=1162) in the Singapore Longitudinal Ageing Study 2 (SLAS-2). MEASUREMENTS The Mini Nutritional Assessment Short-Form (MNA-SF) was used to determine nutritional status, and the Fried's criteria (shrinking, weakness, slowness, exhaustion and inactivity) was used to assess physical frailty phenotype at both baseline and follow-up. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were adjusted for multiple baseline co-variables. RESULTS At baseline, being at risk of malnutrition/malnourished was associated with increased odds of prevalent pre-frailty (OR=2.76, 95% CI=1.86-4.10) and frailty (OR=4.10, 95% CI=1.41-11.9). Baseline robust individuals who were persistently at risk of malnutrition/malnourished showed an increased odds of conversion to being pre-frail/frail at follow-up (OR=3.45, 95% CI=1.00-11.9). Among baseline pre-frail/frail individuals, reversion to being robust were significantly less likely among those who were persistently at risk of malnutrition/malnourished (OR=0.26, 95% CI=0.10-0.67) and those whose baseline normal nutrition worsened at follow-up (OR=0.20, 95% CI=0.06-0.74). CONCLUSION Changes in nutritional states are associated with frailty state transitions, and monitoring changes in nutritional status is recommended for the prevention and severity reduction of frailty among older people in the community.

Abstract
BACKGROUND We investigated the effect of multi-domain lifestyle (physical, nutritional, cognitive) interventions among frail and pre-frail community-living older persons on reducing depressive symptoms. METHOD Participants aged 65 and above were randomly allocated to 24 weeks duration interventions with nutritional supplementation (N=49), physical training (N=48), cognitive training (N=50), combination intervention (N=49) and usual care control (N=50). Depressive symptoms were assessed by the Geriatric Depression Scale (GDS-15) at baseline (0M), 3 month (3M), 6 month (6M) and 12 month (12M). RESULTS Mean GDS scores in the control group increased from 0.52 (0M) and 0.54 (3M) to 0.74 (6M), and 0.83 (12M). Compared to the control group, interventions showed significant differences (∆=change) at 6M for cognitive versus control (∆=-0.39, p=0.021, group*time interaction p=0.14); physical versus control (∆ =-0.37, p=0.026, group*time interaction p=0.13), and at 12M for nutrition versus control (∆ =-0.46, p=0.016, group*time interaction p=0.15). The effect for combination versus control was significant at 6M (∆ =-0.43, p=0.020) and 12M (∆ =-0.51, p=0.005, group*time interaction p=0.026). Estimated 12-month cumulative incidence of depressive symptoms (GDS≥2) relative to control were OR=0.38, p=0.037 (nutrition); OR=0.71, p=0.40 (cognitive); OR=0.39, p=0.042 (physical training) and OR=0.38, p=0.037 (combination). Changes in gait speed and energy level were significantly associated with changes in GDS scores over time. CONCLUSION Multi-domain interventions that reverse frailty among community-living older persons also reduce depressive symptomatology. Public health education and programmatic measures combining nutritional, physical and cognitive interventions for at-risk frail older people may likely benefit psychological wellbeing.

Abstract
OBJECTIVE Our aim of this study was to investigate the association between fish consumption and depressive symptoms in senior ethnic Chinese residents of Singapore. DESIGN A population-based cross-sectional study. SETTING The Singapore Longitudinal Aging Studies (SLAS). PARTICIPANT The study consisted of 2,034 participants from the Singapore Longitudinal Aging Studies (SLAS) project who were at least 55 years old. MEASUREMENTS The presence of depressive symptoms was compared between those who self-reported eating fish at least three times a week versus those who ate fish less often. A score of 5 or greater on the 15-item Geriatric Depression Scale (GDS-15) was the cutoff for being designated as having depressive symptoms. RESULTS Fish intake was associated with a lower prevalence of depressive symptoms ([odds ratio] OR = 0.60, 95% [confidence interval] CI 0.40-0.90; P = .015) after controlling for age, sex, marital status, housing, smoking, alcohol consumption, physical exercise, social and productive activities, self-rated health, hypertension, diabetes, heart failure or attack, stroke, fruit and vegetable intake, and Mini-Mental State Examination (MMSE) scores. CONCLUSION Our results suggest that eating fish at least three times a week is associated with a lower odds of having depressive symptoms among Chinese adults over 55 years old living in Singapore.

Abstract
Background Racial differences in electrocardiographic (ECG) characteristics and prognostic significance among Whites and Asians are not well described. Methods and Results We studied 2677 White Framingham Heart Study participants (57% women) and 2972 Asian (64% women) Singapore Longitudinal Aging Study participants (mean age 66 years in both) free of myocardial infarction or heart failure. Racial differences in ECG characteristics and effect on mortality were assessed. In linear regression models, PR interval was longer in Asians compared with Whites (multivariable‐adjusted β±SE 5.0±1.4 ms in men and 6.6±0.9 ms in women, both P<0.0006). QT interval was shorter in Asian men (β±SE −6.2±1.2 ms, P<0.0001) and longer in Asian women (β±SE 3.6±0.9 ms, P=0.02) compared to White men and women, respectively. Asians had greater odds of having ECG left ventricular hypertrophy (LVH) compared with Whites (odds ratio [OR] 3.56, 95% confidence interval [CI] 1.36–9.35 for men, OR 1.93, 95% CI 1.35–2.76 for women, both P<0.02). Over a mean follow‐up of 11±3 years in Framingham and 8±3 years in Singapore, mortality rates were 24.5 and 13.4 per 1000 person‐years among Whites and Asians, respectively. In Cox models, the presence of LVH had a greater effect on all‐cause mortality in Asians compared with Whites (hazard ratio [HR] 2.66, 95% CI 1.83–3.88 vs HR 1.30, 95% CI 0.90–1.89, P for interaction=0.02). Conclusion Our findings from two large community‐based cohorts show prominent race differences in ECG characteristics between Whites and Asians, and also suggest a differential association with mortality. These differences may carry implications for race‐specific ECG reference ranges and cardiovascular risk.

Abstract
OBJECTIVE To evaluate the effectiveness of various orthotic treatments for patients with isolated medial compartment osteoarthritis. DESIGN Prospective cohort study with sequential interventions. SETTING University-affiliated hospital, Hong Kong. PATIENTS From December 2010 to November 2011, 10 patients with medial knee osteoarthritis were referred by orthopaedic surgeons for orthotic treatment. All patients were sequentially treated with flat insole, lateral-wedged insole, lateral-wedged insole with subtalar strap, lateral-wedged insole with arch support, valgus knee brace, and valgus knee brace with lateral-wedged insole with arch support for 4 weeks with no treatment break. Three-dimensional gait analysis and questionnaires were completed after each orthotic treatment. MAIN OUTCOME MEASURES The Western Ontario and McMaster Universities Arthritis Index (WOMAC), visual analogue scale scores, and peak and mean knee adduction moments. RESULTS Compared with pretreatment, the lateral-wedged insole, lateral-wedged insole with arch support, and valgus knee brace groups demonstrated significant reductions in WOMAC pain score (19.1%, P=0.04; 18.2%, P=0.04; and 20.4%, P=0.02, respectively). The lateral-wedged insole with arch support group showed the greatest reduction in visual analogue scale score compared with pretreatment at 24.1% (P=0.004). Addition of a subtalar strap to lateral-wedged insoles (lateral-wedged insole with subtalar strap) did not produce significant benefit when compared with the lateral-wedged insole alone. The valgus knee brace with lateral-wedged insole with arch support group demonstrated an additive effect with a statistically significant reduction in WOMAC total score (-26.7%, P=0.01). Compliance with treatment for the isolated insole groups were all over 90%, but compliance for the valgus knee brace-associated groups was only around 50%. Gait analysis indicated statistically significant reductions in peak and mean knee adduction moments in all orthotic groups when compared with a flat insole. CONCLUSIONS These results support the use of orthotic treatment for early medial compartment knee osteoarthritis.

Abstract
Natriuretic peptide receptor 3 (NPR3) is the clearance receptor for the cardiac natriuretic peptides (NPs). By modulating the level of NPs, NPR3 plays an important role in cardiovascular homeostasis. Although the physiological functions of NPR3 have been explored, little is known about its regulation in health or disease. MicroRNAs play an essential role in the post-transcriptional expression of many genes. Our aim was to investigate potential microRNA-based regulation of NPR3 in multiple models. Hypoxic challenge elevated levels of NPPB and ADM mRNA, as well as NT-proBNP and MR-proADM in human left ventricle derived cardiac cells (HCMa), and in the corresponding conditioned medium, as revealed by qRT-PCR and ELISA. NPR3 was decreased while NPR1 was increased by hypoxia at mRNA and protein levels in HCMa. Down-regulation of NPR3 mRNA was also observed in infarct and peri-infarct cardiac tissue from rats undergoing myocardial infarction. From microRNA microarray analyses and microRNA target predictive databases, miR-100 was selected as a candidate regulator of NPR3 expression. Further analyses confirmed up-regulation of miR-100 in hypoxic cells and associated conditioned media. Antagomir-based silencing of miR-100 enhanced NPR3 expression in HCMa. Furthermore, miR-100 levels were markedly up-regulated in rat hearts and in peripheral blood after myocardial infarction and in the blood from heart failure patients. Results from this study point to a role for miR-100 in the regulation of NPR3 expression, and suggest a possible therapeutic target for modulation of NP bioactivity in heart disease.

Abstract
AIM The potential diagnostic utility of circulating microRNAs in heart failure (HF) or in distinguishing HF with reduced vs. preserved left ventricular ejection fraction (HFREF and HFPEF, respectively) is unclear. We sought to identify microRNAs suitable for diagnosis of HF and for distinguishing both HFREF and HFPEF from non-HF controls and HFREF from HFPEF. METHODS AND RESULTS MicroRNA profiling performed on whole blood and corresponding plasma samples of 28 controls, 39 HFREF and 19 HFPEF identified 344 microRNAs to be dysregulated among the three groups. Further analysis using an independent cohort of 30 controls, 30 HFREF and 30 HFPEF, presented 12 microRNAs with diagnostic potential for one or both HF phenotypes. Of these, miR-1233, -183-3p, -190a, -193b-3p, -193b-5p, -211-5p, -494, and -671-5p distinguished HF from controls. Altered levels of miR-125a-5p, -183-3p, -193b-3p, -211-5p, -494, -638, and -671-5p were found in HFREF while levels of miR-1233, -183-3p, -190a, -193b-3p, -193b-5p, and -545-5p distinguished HFPEF from controls. Four microRNAs (miR-125a-5p, -190a, -550a-5p, and -638) distinguished HFREF from HFPEF. Selective microRNA panels showed stronger discriminative power than N-terminal pro-brain natriuretic peptide (NT-proBNP). In addition, individual or multiple microRNAs used in combination with NT-proBNP increased NT-proBNP's discriminative performance, achieving perfect intergroup distinction. Pathway analysis revealed that the altered microRNAs expression was associated with several mechanisms of potential significance in HF. CONCLUSIONS We report specific microRNAs as potential biomarkers in distinguishing HF from non-HF controls and in differentiating between HFREF and HFPEF.

Abstract
PURPOSE. To identify prognostic factors associated with clear cell sarcomas in 14 Chinese patients. METHODS. Medical records of 7 men and 7 women (mean age, 36 years) with histologically confirmed clear cell sarcoma of tendons and aponeuroses were reviewed. Patient demographics, tumour characteristics, and treatment modalities were retrieved. Prognostic factors associated with favourable 5-year survival were determined. RESULTS. The most affected sites were the thigh (n=5) and the foot (n=4); the mean time from symptom onset to diagnosis was 9.5 months. The tumour stage at diagnosis was IIA in 8 patients, IIB in 2, and III in 4. The mean tumour size was 4.5 cm in diameter. One patient was lost to follow-up. For the remaining 13 patients, the mean time to disease-related mortality was 2.5 years. Nine patients had distant metastases; the most common sites were lungs and pleura (n=7), followed by distant lymph nodes (n=4), bone (n=2), pericardium (n=2), and brain (n=1). All patients underwent surgical excision. Three women and one man (mean age, 27 years) attained 5-year disease-free survival. All had stage IIA tumours at diagnosis. Their mean tumour size was 1.75 cm in diameter, which was significantly smaller than that of all patients (4.5 cm). Tumour size of ≤ 2.5 cm in diameter (p=0.004) and stage IIA tumour at diagnosis (p=0.04) were significant prognostic factors for 5-year survival. CONCLUSION. Tumour size of ≤ 2.5 cm and early stage tumour are associated with 5-year disease-free survival. Early detection is crucial for the prognosis of clear cell sarcomas.

Abstract
BACKGROUND Tea consumption has been reported to be associated with lowered risk of cardiovascular disease, stroke and osteoporosis that cause functional disability, but its association with physical function has not been investigated directly. OBJECTIVE We examined the association between tea consumption and performance in gait and balance, instrumental and basic activities of daily living (IADL and BADL) in a cross-sectional study of community-living older persons. METHOD Baseline data of 2398 adults aged ≥ 55 years in the Singapore Longitudinal Ageing Studies who completed self-reported current tea consumption, Performance Oriented Mobility Assessment (POMA) of gait and balance, and self reports of BADL and IADL were analyzed. RESULTS In multivariate analyses controlling for age, gender, education, housing type, co-morbidities, hospitalization, arthritis and hip fracture, GDS depression score, MMSE cognitive score, body mass index, creatinine, serum albumin, haemoglobin, physical activities score and coffee consumption, tea consumption was positively associated with better balance (β=0.06, p<0.01), gait (β=0.01, p=0.02), IADL (β=0.03, p=0.01) and BADL (β=0.01, p=0.05). Strongly positive associations were observed for black/oolong tea in multivariate analyses, and for green tea consumption only in univariate analysis, whereas coffee consumption was not associated at all. CONCLUSIONS Tea consumption was associated with better physical functional performances in community-living older adults.

Abstract
This paper discusses the case of a 57-year-old man with an incidental finding of a radiologically non-aggressive chondroid lesion and concomitant osteonecrosis in the left distal femur. The final resected specimen showed a grade-2 chondrosarcoma. This case illustrates that long-term follow-up is necessary for non-aggressive chondroid lesions. If surgical management is considered, resection with an adequate margin is superior to intralesional curettage.

Abstract
AIMS Growth differentiation factor 15 (GDF15), ST2, high-sensitivity troponin T (hsTnT), and N-terminal pro brain natriuretic peptide (NT-proBNP) are biomarkers of distinct mechanisms that may contribute to the pathophysiology of heart failure (HF) [inflammation (GDF15); ventricular remodelling (ST2); myonecrosis (hsTnT); and wall stress (NT-proBNP)]. METHODS AND RESULTS We compared circulating levels of GDF15, ST2, hsTnT, and NT-proBNP, as well as their combinations, in compensated patients with clinical HF with reduced ejection fraction (HFREF) (n = 51), HF with preserved ejection fraction (HFPEF) (n= 50), and community-based controls (n = 50). Compared with controls, patients with HFPEF and HFREF had higher median levels of GDF15 (540 pg/mL vs. 2529 and 2672 pg/mL, respectively), hsTnT (3.7 pg/mL vs. 23.7 and 35.6 pg/mL), and NT-proBNP (69 pg/mL vs. 942 and 2562 pg/mL), but not ST2 (27.6 ng/mL vs. 31.5 and 35.3 ng/mL), adjusting for clinical covariates. In receiver operating characteristic curve analyses, NT-proBNP distinguished HFREF from controls with an area under the curve (AUC) of 0.987 (P < 0.001); GDF15 distinguished HFPEF from controls with an AUC of 0.936 (P < 0.001); and the combination of NT-proBNP and GDF15 distinguished HFPEF from controls with an AUC of 0.956 (P < 0.001). NT-proBNP and hsTnT levels were higher in HFREF than in HFPEF (adjusted P < 0.04). The NT-proBNP:GDF15 ratio distinguished between HFPEF and HFREF with the largest AUC (0.709; P < 0.001). CONCLUSIONS Our study provides comparative data on physiologically distinct circulating biomarkers in HFPEF, HFREF, and controls from the same community. These data suggest a prominent role for myocardial injury (hsTnT) with increased wall stress (NT-proBNP) in HFREF, and systemic inflammation (GDF15) in HFPEF.

Abstract
This report describes a 31-year-old woman with a 23-year history of a right buttock mass that was otherwise asymptomatic, but was proven to be a low-grade fibromyxoid sarcoma (a fully malignant soft tissue tumour with a potential for distant metastasis). This case illustrates that a long-standing tumour does not necessarily imply a benign pathology. A vigilant approach should be taken for any tumours that are of significant size (larger than 5 cm).

Abstract
OBJECTIVES Albumin and hemoglobin are viewed as markers of nutritional and inflammatory status. This study examined the associations of serum albumin and hemoglobin with physical function in community-living older adults. DESIGN Population-based cross-sectional and longitudinal study. SETTING The Singapore Longitudinal Aging Studies (SLAS), a community-based study in urban Singapore. PARTICIPANTS 2762 older adults aged 55 and above assessed at baseline, and 1829 at follow up 1-2 years later. MEASUREMENTS Serum albumin and hemoglobin, Performance Oriented Mobility Assessment (POMA), knee extension strength at baseline, and Instrumental Activities of Daily Living (IADL) at baseline and follow up. RESULTS In cross-sectional multivariate analyses that adjusted for haemoglobin and other confounders, albumin showed a significant linear association (p<0.001) with POMA balance score (b=0.06, SE=0.02) and knee extension strength (b=0.70, SE=0.10). Independently of albumin, hemoglobin also showed a significant linear association with POMA balance score (b=0.09, SE=0.04). In longitudinal analyses, albumin was significantly associated with IADL decline (IADL total score drop>=1 during follow-up), OR= 0.92 (0.87 - 0.97), p=<0.01. CONCLUSION The findings suggest that low levels of albumin and hemoglobin are potentially useful risk markers of physical functional decline in older adults. Further research should investigate whether improvements in the levels of albumin and hemoglobin alter the level of functional disability and risk of functional decline.

Abstract
OBJECTIVE To review the results of arthroscopic treatment of popliteal cysts in our centre and analyse outcomes including complications. DESIGN Retrospective study. SETTING University teaching hospital, Hong Kong. PATIENTS From July 2007 to July 2009, 11 patients with symptomatic popliteal cysts were treated arthroscopically. All of them had preoperative magnetic resonance imaging to confirm the diagnosis, identify the valvular opening, and the associated intra-articular pathology. We used the Rauschning and Lindgren criteria for evaluation. RESULTS Intra-articular pathology like cartilage degeneration and meniscus tear were commonly associated with popliteal cysts. All patients achieved symptomatic improvement after treatment and the recurrence rate was low. No major complications were encountered. We failed to identify (and correct) any valvular opening in one patient. CONCLUSION From our experience, we conclude that arthroscopic treatment of popliteal cyst with correction of the valvular opening and treatment of associated intra-articular pathology is effective and safe.

Abstract
Osteomalacia is uncommon in an affluent subtropical city like Hong Kong, where sunlight exposure is adequate and nutritional support is good. We present three patients who had osteomalacia with different presentations. A 74-year-old male with oncogenic osteomalacia presented with multiple bone pain. His biochemical markers returned to normal 4 days postoperatively after resection of a second toe giant cell tumour of tendon sheath. A 62-year-old woman with a history of liver problem and proximal muscle weakness was admitted with atraumatic fracture of the left distal humerus due to osteomalacia. An 81-year-old vegetarian woman with inadequate sun exposure complained of multiple bone pains. Subsequent investigation revealed dietary- and sunlight-deficient osteomalacia with multiple bony abnormalities including marked femur bowing.

Abstract
This study examines maternal perceptions of paediatric atopic dermatitis (AD) on family and determines risk factors including severity of AD, maternal physical and mental health (MH), quality of life of patients and sociodemographics which predict a negative family impact. A cross-sectional assessment using the Dermatitis Family Impact Questionnaire Scale to assess the impact of AD on family, Infant's Dermatitis Quality of Life Index (<5-yrs old) or Children's Dermatitis Life Quality Index (5-17 yrs old) was used to measure health-related quality of life (HRQOL) of paediatric patients with AD. A 12-item Short-Form Health Survey (SF-12) was used to assess physical and MH of their mothers. Risk factors of adverse family impact were assessed using multiple regression analysis. One hundred and four patients with AD and their mothers were studied. Their mean ages (+/-s.d.) were respectively 6.4 +/- 4.3 and 37.2 +/- 6.6 yrs. In multiple regression analysis, Severity Scoring of Atopic Dermatitis (SCORAD) appeared to be associated with negative family impact and the association remained significant after adjustment for bio-psycho-social factors and HRQOL of patients. The association remained insignificant after adjustment for physical and MH of the mothers. Our results show that the severity of paediatric AD leads to negative family impact through reduction of physical and MH of the mothers, and is independent of patients' HRQOL and sociodemographics. The current approach for managing paediatric AD in Asian society could include early multidisciplinary intervention, aiming at enhancing physical and MH of mothers while minimizing negative impact on family and social isolation. Further research will be welcomed as the results of this study mainly applied to Asian society which could be different to populations from other geographic areas.

Abstract
PURPOSE To assess inter- and intra-observer errors in identifying the transepicondylar axis and Whiteside's line in a cadaveric model mimicking total knee arthroplasty. METHODS Four cadaveric knees with intact soft tissues were used. The knees were exposed anteriorly using the Insall approach, with the patella everted laterally. Three observers (2 surgeons and one trainee) took turns to identify the anatomic landmarks of the transepicondylar axis and Whiteside's line. Each observer repeated the process 20 times. Each identification was photographed and referenced with the true values obtained from the knees after they were stripped of all soft tissue. Inter- and intra-observer errors in the anatomic landmarks were compared. RESULTS Inter-observer error was significant with both the transepicondylar axis and Whiteside's line (p<0.001, one-way ANOVA). The intra-observer variation was greater for Whiteside's line than the transepicondylar axis (standard deviation, 4.2 vs 2.5 degrees). The maximum potential errors in the transepicondylar axis and Whiteside's line were 13 degrees and 24 degrees, respectively. CONCLUSION The accuracy of rotational alignment of the transepicondylar axis and Whiteside's line were operator-dependent, and their intra-operative reproducibility was low.

Abstract
Arthrodesis of the hip has been employed since the late 19th century. Late complications can arise decades after fusion in patients who were previously asymptomatic. We describe two patients who developed pain in the hip many years after a successful fusion. There was no infection or loosening of the implants. After careful investigation, including oblique radiographs and diagnostic injections of local anaesthetic, the pain was found to be caused by protrusion of the implant. Subsequent removal of the device resulted in complete resolution of the symptoms.

Abstract
BACKGROUND The Geriatric Depression Scale (GDS) is widely used for screening and assessment of major depressive disorder (MDD). Screening scales are often culture-specific and should be evaluated for item response bias (synonymously differential item functioning, DIF) before use in clinical practice and research in a different population. In this study, we examined DIF associated with age, gender, ethnicity and chronic illness in a heterogeneous Asian population in Singapore. METHODS The GDS-15 and Structured Clinical Interview for DSM-IV diagnosis of MDD were independently administered by interviewers on 4253 non-institutionalized community living elderly subjects aged 60 years and above who were users of social service agencies. Multiple Indicator Multiple Cause latent variable modelling was used to identify DIF. RESULTS We found evidence of significant DIF associated with age, gender, ethnicity and chronic illness for 8 items: dropped many activities and interests, afraid something bad is going to happen, prefer staying home to going out, more problems with memory than most, think it is (not) wonderful to be alive, feel pretty worthless, feel (not) full of energy, feel that situation is hopeless. LIMITATIONS The smaller number of minority Indian and Malay subjects and the self-report of chronic medical illnesses. CONCLUSIONS In a heterogeneous mix of respondents in Singapore, eight items of the GDS-15 showed DIF for age, gender, ethnicity and chronic illness. The awareness and identification of DIF in the GDS-15 provides a rational basis for its use in diverse population groups and guiding the derivation of abbreviated scales.

Abstract
BACKGROUND Perinatal depression is common, but women typically do not seek help for it. We studied its association with frequent non-routine physician visits, which may be a form of help-seeking behaviour. METHODS A prospective cohort study of women in their 34th to 38th week of pregnancy at the outpatient obstetrics clinic at a Singapore tertiary hospital was done. Screening was done using the Edinburgh Postnatal Depression Scale and diagnosis of major or minor depressive disorder was made using the SCID-IV. At 6 to 12 months' post-partum, women were screened and interviewed again for depression and asked to report the frequencies with which they had brought their infants to the doctor on non-routine visits in the preceding 6 weeks. Four hundred and seventy-one of the 559 patients recruited before delivery were re-interviewed. RESULTS After adjusting for confounders, women who had brought their infants for three or more non-routine visits to the infant's doctor had a significantly higher prevalence of depression (32.6%) than those with fewer visits (13.6%) (OR 2.87, 95% CI 1.41 to 5.85, p=0.004). The relative risk reduction for women who did not bring their infants for frequent non-routine visits was 0.583 (95% CI 0.44 to 0.73, p=0.002). They were also more likely to have poorer perceived emotional support from their families. LIMITATIONS These included use of self-reported doctor visits, and relatively high educational levels of the participants. CONCLUSIONS Doctors should have a high index of suspicion for enquiring about depression and emotional support in mothers who bring their infants for frequent non-routine visits.

Abstract
COPD is a global health concern, and is a major cause of chronic morbidity and mortality worldwide. According to the World Health Organization, it is currently the sixth leading cause of death in the world, and further increases in the prevalence and mortality of the disease is predicted for the coming decades. These increases are mainly linked to the epidemic of tobacco exposure and indoor and outdoor air pollution in Asian countries. The burden of COPD in Asia is currently greater than that in developed Western countries, both in terms of the total number of deaths and the burden of disease, as measured in years of life lost and years spent living with disability. The types of health-care policies and the practice of medicine vary considerably among the regions of Asia and have an impact on the burden of disease. Treatment aims in Asian countries are based on evidence-based management guidelines. Barriers to the implementation of disease management guidelines are related to issues of resource conflict and lack of organizational support rather than cultural differences in medical practice. To reduce this burden of COPD in Asian countries, there is a need for a multifaceted approach in improving awareness of prevalence and disease burden, in facilitating accurate diagnosis of COPD among chronic respiratory diseases, in championing health policies that reduce the burden of the main risk factors for COPD and in the wider use of evidence-based management for COPD.

Abstract
BACKGROUND Subthreshold depression (sD) and cognitive impairment but not demented (CIND) in stroke patients are associated with poorer rehabilitative outcomes. Their diagnosis can easily be operationalized using validated scales. AIM The aim of the study was to ascertain the prevalence of depressive symptoms and cognitive impairment in stroke patients during three crucial stages of the rehabilitative process, viz. upon admission, upon planned discharges from rehabilitation hospitals and at 6 months post-stroke, using validated scales like the Geriatric Depression Scale and Abbreviated Mental Test (recommended by the British Geriatric Society). Their baseline risk factors were also ascertained. RESULTS On admission, the prevalence of depressive symptoms and cognitive impairment was 60% and 54% respectively. The prevalence upon planned discharges and 6 months post-stroke, respectively, of depressive symptoms was 38% and 34% and that of impaired cognition was 33% and 40%. Baseline independent correlates at 6 months post-stroke depressive symptoms were: recurrent stroke (OR 3.34); on admission cognitive impairment (OR 4.78) and ADL dependence (OR 5.28). And that of cognitive impairment were: increasing age (OR 8.07); post-stroke dysphagia (OR 4.58); on admission cognitive impairment (OR 23.95) and on admission depressive symptoms (OR 3.50). CONCLUSIONS Continuous screening and appropriate intervention, especially at baseline, would significantly decrease the burden posed by stroke patients with such psychological impairments in the community.

Abstract
INTRODUCTION This study aims to determine the prevalence of emotional and behavioural problems in a community sample of Singaporean children aged 6-12 years, and its agreement according to parent, teacher and child reports. METHODS The Child Behaviour Checklist (CBCL), Teacher Rating Form (TRF) and child report questionnaires for depression and anxiety were administered to a community sample of primary school children. 60 percent of the children sampled (n = 2,139) agreed to participate. Parents of a sub-sample of 203 children underwent a structured clinical interview. RESULTS Higher prevalence of emotional and behavioural problems was identified by CBCL (12.5 percent) than by TRF (2.5 percent). According to parent reports, higher rates of internalising problems (12.2 percent) compared to externalising problems (4.9 percent), were found. Parent-teacher agreement was higher for externalising problems than for internalising problems. Correlations between child-reported depression and anxiety, and parent and teacher reports were low to moderate, but were better for parent reports than for teacher reports. CONCLUSION The prevalence rates of emotional and behavioural problems in Singaporean children based on CBCL ratings are comparable to those in the West, but the low response rate and exclusion of children with special needs limit the generalisability of our findings. Singaporean children have higher rates of internalising problems compared to externalising problems, while Western children have higher rates of externalising problems compared to internalising problems.

Abstract
We presented a simple and economic method of preparing articulating antibiotic-loaded cement spacers for treatment of infection after total knee arthroplasty. From 1996 to 2004, 28 infected total knee arthroplasties were treated with 2-stage reimplantation. Static spacers were used in 7 knees, and articulating spacers were used in 21 knees. A minimum of 2 years' follow-up after final treatment was evaluated. In the static group, 1 (14%) knee had recurrence of infection. In the articulating group, 2 (9%) knees had recurrence of infection with the original organism. Patients receiving articulating spacer had better range of motion, better knee score, and less bone loss than patients with static spacer.

Abstract
INTRODUCTION This study aimed to describe responses to the DETERMINE checklist and the nutritional risk level of community-dwelling older Chinese in Singapore, aged 55 years and older. METHODS Data was collected from a community health screening project for elderly residents in Singapore. All residents aged 55 years and older in the survey area were identified in door-to-door census surveys and were invited to participate. Participants completed a questionnaire interview conducted by research nurses. The survey also included questions which were potential predictors of nutritional risk: sociodemographic factors (age, gender, education, housing type, marital status, and living arrangement) and health-related factors (self-rated health, number of medical comorbidities, hospitalisations in the past year, functional disabilities and physical health status). RESULTS Data for analysis was provided by 2,605 Chinese subjects aged between 55 and 98 years (mean/standard deviation 66.0/7.7). The overall prevalence of nutritional risk (according to a DETERMINE score of 3 or greater) was 30.1 percent. 1,822 (69.9 percent) subjects had no nutritional risk (scores of 2 or lower), 664 (25.5 percent) had moderate nutritional risk and 119 (4.6 percent) had high nutritional risk. The most common contributions to nutritional risks were: changing food intake due to illness (40.3 percent), taking three or more different medications daily (25.0 percent), eating alone (14.5 percent) and consuming insufficient amount of fruits, vegetables or milk products on a daily basis (9.0 percent). Respondents at nutritional risk were more likely to have three or more comorbid medical conditions, were hospitalised in the past year, were functionally dependent on one or more instrumental or basic activities of daily living, were reported to have poor or fair self-rated health, and were in the lowest tertile scores for SF-12 quality of life and depression. CONCLUSION Self-rated general health, lowered quality of life, functional disability and depression have meaningful non-circular associations with the checklist. These support the validity of the DETERMINE checklist in predicting the risk of adverse health conditions and events.

Abstract
AIM This paper is a report of a study to assess the effect of an adapted arthritis self-management programme with an added focus on exercise practice among osteoarthritic knee sufferers. BACKGROUND Osteoarthritis of the knee is a major source of loss of function in older people. Previous studies have found self-management programmes to be effective in increasing arthritis self-efficacy and in mastery of self-management practice. METHOD A randomized control trial was carried out from December 2002 to May 2003 and 120 participants (65.9%, including 67 in intervention group and 53 in control group) completed the 16-week postintervention assessments. Outcome measures included arthritis self-efficacy, use of self-management techniques, pain intensity and daily activity. FINDINGS At 16 weeks, there was a 'statistically' significant improvement in the arthritis self-efficacy level (P <or= 0.001), in most of the self-management skills, i.e. use of cold and hot compresses, in two of three joint protective practices (P <or= 0.001; P = 0.01), an increase in the duration of light exercise practice (P <or= 0.001), reduction of current arthritis pain (P <or= 0.001) and in the ability to perform daily activities (P <or= 0.001) among the intervention group but not for the control group (P-range from 0.04 to 0.95). One joint protective practice showed a statistically significant increase in both groups (P <or= 0.001). CONCLUSION Our findings add to evidence showing short-term beneficial effects of self-efficacy theory in education programmes. Self-efficacy theory has great potential for empowering sufferers of chronic conditions to live with their illness.

Abstract
Mal-rotation of pelvis on the sagittal plane, which is common in patients with fixed spinal kyhposis, for example, ankylosing spondylitis, can cause error in cup positioning when hip arthroplasty is performed. The present study was performed to quantify the effects of sagittal pelvic mal-rotation on the final cup position and to evaluate different methods of cup positioning to compensate for the mal-rotation. Three-dimensional reconstruction of computer tomograms of 15 sets of full pelvi was performed. Two methods of cup insertion were simulated and compared: a method mimicking genuine surgery (anatomical positioning) and one that compensates for the sagittal pelvic mal-rotation (functional positioning). Sagittal pelvic mal-rotation of more than 20 degrees , if ignored, resulted in a cup with an anterversion of more than 30 degrees and an inclination of more than 55 degrees. Half of the cup surface was not in contact with host bone when the cup position was maintained at 20 degrees anteversion and 45 degrees inclination in a patient with 50 degrees sagittal pelvic mal-rotation. The usual method of cup positioning may need to be modified in patients with sagittal pelvic mal-rotation in order to maintain the desired cup position. For each 10 degrees of sagittal pelvic mal-rotation beyond 20 degrees of mal-rotation, the cup needs to be put in such that it is 5 degrees less inclined and anteverted.

Abstract
AIM Because of a high childhood asthma burden in Singapore, assessment of disease control status is essential for formulating school-based strategy of childhood asthma control. The aim of the present study is to assess childhood asthma prevalence and control in Singapore and the socio-demographic and help-seeking correlates. METHODS School-based survey using parental self-administered questionnaire, conducted from February to April 2004. Four mixed-gender primary schools selected from geographically distinct zones of Singapore. All primary one (modal age - 6.5 years) and six (modal age - 11.9 years) students from selected schools were invited to participate. Questionnaire respondents were the students' parents or guardians. The response rate was 75.2% (2123/2825). RESULTS Prevalence of current asthma was 8.9% (190/2123). Among them, 26.3% (46/175) were assessed to have inadequate control. Asthma was more prevalent, and less adequately controlled in children from lower socio-economic backgrounds (lower-end housing type). Children with poorly controlled asthma were more likely to be treated by emergency room physicians and hospital specialists, and to be on preventer medications. CONCLUSIONS In Singapore, poor asthma control is found in a sizeable proportion of school children with asthma, is identifiable for high-risk groups of children from lower socio-economic backgrounds and having asthma-related attendance at the emergency rooms.

Abstract
INTRODUCTION Length of stay (LOS) in hospitals is the largest contributor of direct stroke care cost. Rehabilitation accounts for 16 percent of healthcare cost in the six-month post-stroke period. It is important to determine factors extending LOS in rehabilitation hospitals to identify focus areas of cost-control strategies. The aim of the study was to ascertain the predictors of LOS of post-stroke patients admitted into two community hospitals offering rehabilitation. METHODS An observational cohort study was conducted on 200 stroke patients admitted from acute hospitals into two community hospitals. Data collected included baseline sociodemographical variables, and the National Institute of Health Stroke Scale, Abbreviated Mental Test, Geriatric Depression Scale and Barthel Index were used to assess neurological impairment, cognitive impairment, depressive symptoms and functional disability, respectively. Medical complications (defined as new or exacerbated medical problems that generated additional physician evaluation, a change in medication or additional medical intervention), after patients were admitted to the community hospitals until discharged, were recorded. The outcome variables measured were length and cost of stay. RESULTS The mean LOS in our study was 34.4 (standard deviation [SD] 18.4) days, and the mean cost of hospital stay was S$2,410.83 (SD S$2,167.26). Length and cost of hospital stay were significantly correlated (r equals 0.52; p-value is less than 0.01). On multiple linear regression analysis, the significant variables positively associated with LOS were medical complications and functional dependence on admission. Significant variables negatively associated with LOS were unplanned discharge and recurrent strokes. CONCLUSION Medical complication is a key reversible determinant of increased LOS of post-stroke patients receiving rehabilitation in community hospitals. Strategies for prevention, early detection and treatment of medical complications during stroke rehabilitation are discussed.

Abstract
PURPOSES To study the incidence of femoral or tibial bowing in the coronal plane in a Chinese population, and how it affects the accuracy of bone cuts for total knee replacement when an intramedullary alignment system is used. METHODS Standing radiographs of the entire lower limb of each patient with end-stage primary osteoarthritis of the knee were analysed. All radiographs were digitised and the extent of bowing in the coronal plane measured. A bowing was marked if an angulation was more than 2 degrees. The projected error of cutting was then calculated. RESULTS Of 93 lower limbs, 58 (62%) of the femurs had marked bowing in the coronal plane; 41 (44%) had a mean lateral bowing of 5.3 (standard deviation [SD], 3.2) degrees; 17 (18%) had a mean medial bowing of 4.4 (SD, 1.9) degrees. Marked tibial bowing in the coronal plane was less common (30 tibias, 32%). If a cutting error of more than 2 degrees was considered unacceptable, significantly more unacceptable cuts would ensue in the groups with marked bowing (p=0.003 for femurs and p<0.001 for tibia, respectively). CONCLUSION The incidence of femoral or tibial bowing in the coronal plane was high in a Chinese population with end-stage osteoarthritis of the knee. This phenomenon may increase bone cut errors in total knee replacement if an intramedullary alignment system is used and the extent of bowing is not recognised.
