    We performed a hospital-based study to examine a hypothesis that indoor air pollution was associated with acute asthma in young children living in Kuala Lumpur City. A total of 158 children aged 1 month to 5 years hospitalized for the first time for asthma were recruited as cases. Controls were 201 children of the same age group who were hospitalized for causes other than a respiratory illness. Information was obtained from mothers using a standardized questionnaire. Univariate analysis identified two indoor pollution variables as significant factors. Sharing a bedroom with an adult smoker and exposure to mosquito coil smoke at least three nights in a week were both associated with increased risk for asthma. Logistic regression analysis confirmed that sharing a bedroom with an adult smoker (OR = 1.91, 95% CI 1.13, 3.21) and exposure to mosquito coil smoke (OR = 1.73, 95% CI 1.02, 2.93) were independent risk factors. Other factors independently associated with acute asthma were previous history of allergy, history of asthma in first-degree relatives, low birth weight, and the presence of a coughing sibling. There was no association between asthma and exposure to kerosene stove, wood stove, aerosol mosquito repellent, type of housing, or crowding. We conclude that indoor air pollution is an avoidable factor in the increasing morbidity due to asthma in children in a tropical environment.

    This report provides a comprehensive analysis of gender differences in economic support and well-being in eight countries in Southern and Eastern Asia (Bangladesh, Malaysia, Indonesia, Singapore, Thailand, Vietnam, Philippines, and Taiwan). We examine multiple economic indicators, including sources of income, receipt of financial and material support, income levels, ownership of assets, and subjective well-being. Results show substantial variation in gender differences across indicators and provide an important qualification to widely held views concerning the globally disadvantaged position of older women. Whereas men tend to report higher levels of income than women, there is generally little gender difference in housing characteristics, asset ownership, or reports of subjective economic well-being. Unmarried women are economically advantaged compared to unmarried men in some respects, in part because they are more likely to be embedded in multigenerational households and receive both direct and indirect forms of support from family members.

    RATIONALE: Aside from blood pressure lowering, treatment options for intracerebral haemorrhage remain limited and a proportion of patients will undergo early haematoma expansion with resultant significant morbidity and mortality. Tranexamic acid (TXA), an anti-fibrinolytic drug, has been shown to significantly reduce mortality in patients, who are bleeding following trauma, when given rapidly. TICH-2 is testing whether TXA is effective at improving outcome in spontaneous intracerebral haemorrhage (SICH).

    METHODS AND DESIGN: TICH-2 is a pragmatic, phase III, prospective, double-blind, randomised placebo-controlled trial. Two thousand adult (aged ≥ 18 years) patients with an acute SICH, within 8 h of stroke onset, will be randomised to receive TXA or the placebo control. The primary outcome is ordinal shift of modified Rankin Scale score at day 90. Analyses will be performed using intention-to-treat.

    RESULTS: This paper and its attached appendices describe the statistical analysis plan (SAP) for the trial and were developed and published prior to database lock and unblinding to treatment allocation. The SAP includes details of analyses to be undertaken and unpopulated tables which will be reported in the primary and key secondary publications. The database will be locked in early 2018, ready for publication of the results later in the same year.

    DISCUSSION: The SAP details the analyses that will be done to avoid bias arising from prior knowledge of the study findings. The trial will determine whether TXA can improve outcome after SICH, which currently has no definitive therapy.

    BACKGROUND/OBJECTIVES: The role of long-term alcohol consumption for the risk of developing ulcerative colitis (UC) and Crohn's disease (CD) is unclear. For the first time, to prospectively assess the role of pre-disease alcohol consumption on the risk of developing UC or CD.

    SUBJECTS/METHODS: Nested within the European Prospective Investigation into Cancer and Nutrition (EPIC-IBD), incident UC and CD cases and matched controls where included. At recruitment, participants completed validated food frequency and lifestyle questionnaires. Alcohol consumption was classified as either: non-use, former, light (⩽0.5 and 1 drink per week), below the recommended limits (BRL) (⩽1 and 2 drinks per day), moderate (⩽2.5 and 5 drinks per day), or heavy use (>2.5 and >5 drinks per day) for women and men, respectively; and was expressed as consumption at enrolment and during lifetime. Conditional logistic regression was applied adjusting for smoking and education, taking light users as the reference.

    RESULTS: Out of 262 451 participants in six countries, 198 UC incident cases/792 controls and 84 CD cases/336 controls were included. At enrolment, 8%/27%/32%/23%/11% UC cases and 7%/29%/40%/19%/5% CD cases were: non-users, light, BRL, moderate and heavy users, respectively. The corresponding figures for lifetime non-use, former, light, BRL, moderate and heavy use were: 3%/5%/23%/44%/19%/6% and 5%/2%/25%/44%/23%/1% for UC and CD cases, respectively. There were no associations between any categories of alcohol consumption and risk of UC or CD in the unadjusted and adjusted odds ratios.

    CONCLUSION: There was no evidence of associations between alcohol use and the odds of developing either UC or CD.

    BACKGROUND: Factors associated with surgery, adjuvant radiotherapy, and chemotherapy and whether there were missed opportunities for treatment in elderly patients were determined in an Asian setting.

    METHODS: All 5616 patients, diagnosed with breast cancer in University Malaya Medical Centre from 1999 to 2013 were included. In 945 elderly patients (aged 65 years and above), multivariable logistic regression was performed to identify factors associated with treatment, following adjustment for age, ethnicity, tumor, and other treatment characteristics. The impact of lack of treatment on survival of the elderly was assessed while accounting for comorbidities.

    RESULTS: One in five elderly patients had comorbidities. Compared to younger patients, the elderly had more favorable tumor characteristics, and received less loco-regional treatment and chemotherapy. Within stage I-IIIa elderly breast cancer patients, 10 % did not receive any surgery. These patients were older, more likely to be Malays, have comorbidities, and bigger tumors. In elderlies with indications for adjuvant radiotherapy, no irradiation (30 %) was associated with increasing age, comorbidity, and the absence of systemic therapy. Hormone therapy was optimal, but only 35 % of elderly women with ER negative tumors received chemotherapy. Compared to elderly women who received adequate treatment, those not receiving surgery (adjusted hazard ratio: 2.30, 95 %CI: 1.10-4.79), or radiotherapy (adjusted hazard ratio: 1.56, 95 %CI: 1.10-2.19), were associated with higher mortality. Less than 25 % of the survival discrepancy between elderly women receiving loco-regional treatment and no treatment were attributed to excess comorbidities in untreated patients.

    CONCLUSION: While the presence of comorbidities significantly influenced loco-regional treatment decisions in the elderly, it was only able to explain the lower survival rates in untreated patients up to a certain extent, suggesting missed opportunities for treatment.

    BACKGROUND: Suicide is a major global mental health problem among college students. The aim of the current study was to explore the association between the psychological strains of the strain theory of suicide and suicidal behaviors among college students.

    METHODS: Participants comprised 1912 college students (16-28 years old, 47.2% female) from three universities in Jilin Province, China, who completed the self-report assessments of psychological strains (40 items Psychological Strains Scale) and suicidal behaviors (Suicidal Behaviors Questionnaire-Revised). The demographic characteristics included four variables: health status, psychological status, academic status and economic status.

    RESULTS: Approximately 15.0% (286/1912) of participants were classified as having suicide risk, based on the cut-off scores of the SBQ-R. The prevalence of suicidal behaviors among males and females was 11.9% (120/1009) and 18.4% (166/903), respectively. Value strain (OR = 1.075, 95%CI: 1.057-1.094), aspiration strain (OR = 1.082, 95%CI: 1.064-1.101), deprivation strain (OR = 1.073, 95%CI: 1.052-1.093), and coping strain (OR = 1.095, 95%CI: 1.075-1.116) were risk factors for suicidality in college students. Coping strain (OR = 1.050, 95%CI: 1.023-1.077) was still positively associated with suicide risk in multivariate logistic regression. Logistic regression analysis indicated that coping strain had the highest correlation with suicidal behaviors.

    LIMITATIONS: The directionality of the relationships cannot be deduced because this study is cross-sectional.

    CONCLUSION: This study confirms a strong association between psychological strains and suicidal behaviors in college students. Some measures can be taken to reduce psychological strains to mitigate suicide risk among college students. More studies investigating coping strain among college students are warranted.

    BACKGROUND: Underestimation of leptospirosis cases is happening in many countries. The most common factor of underreporting is misdiagnosis. Considering the limitations of direct detection of pathogen and serological diagnosis for leptospirosis, clinical features and blood tests though non-specific are usually referred in making presumptive diagnosis to decide disease management.

    METHODS: In this single-centre retrospective study, comparative analysis on clinical presentations and laboratory findings was performed between confirmed leptospirosis versus non-leptospirosis cases.

    RESULTS: In multivariate logistic regression evidenced by a Hosmer-Lemeshow significance value of 0.979 and Nagelkerke R square of 0.426, the predictors of a leptospirosis case are hypocalcemia (calcium <2.10mmol/L), hypochloremia (chloride <98mmol/L), and eosinopenia (absolute eosinophil count <0.040×109/L). The proposed diagnostic scoring model has a discriminatory power with area under the curve (AUC) 0.761 (p<0.001). A score value of 6 reflected a sensitivity of 0.762, specificity of 0.655, a positive predictive value of 0.38, negative predictive value of 0.91, a positive likelihood ratios of 2.21, and a negative likelihood ratios of 0.36.

    CONCLUSION: With further validation in clinical settings, implementation of this diagnostic scoring model is helpful to manage presumed leptospirosis especially in the absence of leptospirosis confirmatory tests.

    OBJECTIVES: To determine the relationship between falls and deficits in specific cognitive domains in older adults.

    DESIGN: An analysis of the English Longitudinal Study of Ageing (ELSA) cohort.

    SETTING: United Kingdom community-based.

    PARTICIPANTS: 5197 community-dwelling older adults recruited to a prospective longitudinal cohort study.

    MEASUREMENTS: Data on the occurrence of falls and number of falls, which occurred during a 12-month follow-up period, were assessed against the specific cognitive domains of memory, numeracy skills, and executive function. Binomial logistic regression was performed to evaluate the association between each cognitive domain and the dichotomous outcome of falls in the preceding 12 months using unadjusted and adjusted models.

    RESULTS: Of the 5197 participants included in the analysis, 1308 (25%) reported a fall in the preceding 12 months. There was no significant association between the occurrence of a fall and specific forms of cognitive dysfunction after adjusting for self-reported hearing, self-reported eyesight, and functional performance. After adjustment, only orientation (odds ratio [OR]: 0.80; 95% confidence intervals [CI]: 0.65-0.98, p = 0.03) and verbal fluency (adjusted OR: 0.98; 95% CI: 0.96-1.00; p = 0.05) remained significant for predicting recurrent falls.

    CONCLUSIONS: The cognitive phenotype rather than cognitive impairment per se may predict future falls in those presenting with more than one fall.

    INTRODUCTION: Psychological morbidities are common amongst healthcare professionals particularly among junior house officers (HO) who are in a transitional stage from being a medical student to a doctor. They undergo many stressors during this period and hence might suffer from higher psychological morbidities such as depression, anxiety and stress.

    OBJECTIVES: To determine the prevalence of depression, anxiety and stress among HO in Sarawak General Hospital (SGH), Kuching, Sarawak. The socialdemographic factors were also evaluated to identify the high-risk groups.

    MATERIALS AND METHODS: This is a descriptive cross-sectional study involving 227 house officers in SGH over a period of three months. The social-demographic data such as age, sex, marital status, current posting, duration of posting, place of graduate and state of origin were obtained from interviews with the respondents. The Depression, Anxiety and Stress scale (DASS) questionnaire was completed to assess the psychological morbidities.

    RESULTS: HO were found to have high prevalence of psychiatric morbidities such as depression (42%), anxiety (50%) and stress (42.7%). Foreign graduates showed a significantly higher odds of depression (odds ratio, OR: 3.851; 95% confidence interval, 95%CI: 2.165, 6.851), anxiety (OR: 2.427; 95%CI: 1.394, 4.225) and stress (OR: 2.524; 95%CI: 1.439, 4.427) as compared to local graduates.. Further, non-Sarawakians were observed to have higher odds of developing anxiety (OR: 1.772; 95%CI: 1.022, 3.073) as compared to the Sarawakians.

    CONCLUSION: HO in SGH had high prevalence of depression, anxiety and stress. Therefore, psychiatric morbidities should be screened regularly amongst the HOs in Malaysia.

    Aim Potentially inappropriate medications (PIMs) in older people are associated with the increased use of health care services. The aim of this study was to investigate the prevalence of PIMs among the elderly being referred to pharmacies in Tehran using the Beers criteria of 2012, and identify factors related to PIMs. Methods This cross-sectional study was conducted on elderly patients (60 years and above) referred to pharmacies in Tehran, in 2017. The Beers' criteria 2012 were used to evaluate PIMs. The logistic regression analysis was used to find sociodemographic predictors of PIMs. Results The mean age of 1591 patients was 70.51 years. The overall prevalence of PIMs was 26.0%. The most frequent PIMs, in order of frequency, included diclofenac (13.5%), alprazolam (9.3%), and chlordiazepoxide (9.1%) and clonazepam (8.4%). The pain medications were found to be most common PIMs (37.6%). Polypharmacy (OR=3.64, CI 95%: .81-4.70; p<0.001), number of chronic disease (OR=2.371, CI 95%:1.71-3.28; p<0.001) insomnia (OR=1.45, CI 95%: 1.13-1.87; p<0.01) and type of specialists were found as PIMs risk factors. Internal medicine specialists prescribed PIMs significantly fewer times than other specialists(OR=0.59, CI 95%: 0.40-0.88; p<0.01, and the orthopedic specialists prescribed PIMs significantly more times than other physicians (OR=3.23, CI 95%: 5.76-1.81; p<0.001). Conclusion High prevalence of PIMs among Iranian elderly patients implies a need for the development and operationalization of scientific guidelines for the use of medicines. It is also necessary to hold training courses for physicians to be educated in such cases.

    Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with adverse effects. However, NSAIDs are among the most popular pain killers and easily available over the counter. This study aimed to determine the prevalence of NSAIDs use in Malaysian adults and among those with chronic diseases such as arthritis, kidney disease, hypertension, heart disease and asthma. It also examined the factors associated with NSAIDs use. Data from the National Health Morbidity Survey (NHMS) 2011, a nation-wide survey was analysed. A total of 18231 respondents aged 18 years and above responded to this module. Multivariate logistic regression was used to investigate the association between NSAIDs use and associated factors. The overall prevalence of NSAIDs use among Malaysian adults was 14.2% (95%CI 13.3-15.1). Of the respondents, 4.2% (95%CI 3.8-4.7) took NSAIDs once daily. NSAIDs use was highly associated with those who were ever-told to have arthritis (aOR: 3.03; 95%CI 2.60-3.52) and have difficulty of performing daily activities or work (aOR: 2.06; 95%CI 1.86-2.28). Those who were ever-told to have kidney disease (aOR: 2.36; 95%CI 1.74-3.20), ever-told to have asthma (aOR: 1.36; 95%CI 1.17-1.58), ever-told to have heart disease (aOR: 1.34; 95%CI 1.08-1.65), known hypertension (aOR: 1.22; 95%CI 1.08-1.37) also were associated with NSAIDs use. By socio-demographic profiles, NSAIDs use was positively associated with those who have government benefit scheme or private health insurance (aOR: 1.44; 95%CI 1.31-1.58), higher education level (aOR: 1.35; 95%CI 1.20-1.51), higher household income (aOR: 1.26; 95%CI 1.11-1.44, aOR: 1.12; 95%CI 1.02-1.24), currently working (aOR: 1.25; 95%CI 1.13-1.39) and female (aOR: 1.17; 95%CI 1.07-1.28). NSAIDs use was less likely among those aged 60 years and above (aOR: 0.83; 95% CI 0.72-0.97), Chinese (aOR: 0.41; 95% CI 0.36-0.47) and ‘Others’ ethnicity (aOR: 0.82; 95% CI 0.67-0.99) compared to Malay ethnicity. NSAIDs use is prevalent in Malaysian adults and associated with co-morbidities and higher socio-demographic status, thus appropriate awareness should be promoted and highlighted in the community.

    Introduction: A geriatric syndrome is a group of signs and symptoms that occur in older people and do not fit into a discrete disease. Several medications were reported to be associated with the incidence of geriatric syndromes.

    Objective: The objective of this study was to investigate the prevalence and pattern of medications associated with geriatric syndromes (MAGSs) among the discharged elderly patients (≥65 years old).

    Materials and Methods: This is a cross-sectional study that was conducted at a Malaysian teaching hospital from October to December 2018. The discharge medications of geriatric patients were reviewed to identify MAGSs using Beers criteria, Lexicomp drug information handbook, and the United States Food and Drug Administration (USFDA) drug inserts. Chi-square test was used to compare MAGS prescribed between categories. Spearman's rank-order correlation was used to test the correlation between the presence of MAGS and the number of discharge medications. A binomial logistic regression was applied to determine the predictors of prescribing MAGSs.

    Results: A total of 400 patients (mean ± standard deviation [SD] age, 72.0 ± 5.0 years) were included, and 45.3% of them were females. The most common diseases were hypertension followed by diabetes mellitus. The mean ± SD number of discharge medications per patient was 4.2 ± 2.5. The MAGSs were prescribed in 51.7% of the patients, and 54 patients were discharged with more than one MAGSs. The most commonly prescribed MAGSs were opioid analgesics, vasodilators, and β-blockers, which are associated with falls, depression, and delirium. Polypharmacy was found in 138 patients, and it was significantly associated with the presence of MAGSs (P < 0.001). No significant differences were found in prescribing MAGSs based on the patients' gender, race, and age.

    Conclusion: The prescribing of MAGSs occurred in half of the discharged elderly patients. Physicians should be aware of the medications that are associated with special side effects in the elderly patients, and should switch to safer alternatives when possible.

    BACKGROUND & AIMS: Affordable point-of-care (POC) tests for hepatitis C (HCV) viraemia are needed to improve access to treatment in low and middle income countries (LMICs). Our aims were to determine the target limit of detection (LOD) necessary to diagnose the majority of persons with HCV eligible for treatment, and identify characteristics associated with low-level viraemia (LLV) (defined as the lowest 3% of the distribution of HCV RNA) to understand those at risk of being mis-diagnosed.

    METHODS: We established a multi-country cross-sectional dataset of first available quantitative HCV RNA linked to demographic and clinical data. We excluded individuals on HCV treatment. We analyzed the distribution of HCV RNA and determined critical thresholds for detection of HCV viraemia. We then performed logistic regression to evaluate factors associated with LLV, and derived relative sensitivities for significant covariates.

    RESULTS: The dataset included 66,640 individuals with HCV viraemia from Georgia (44.4%), Canada (40.9%), India (8.1%), Cambodia (2.6%), Egypt (1.6%), Pakistan (1.3%), Cameroon (0.4%), Indonesia (0.2%), Thailand (0.2%), Vietnam (0.1%), Malaysia (0.05%), and Mozambique (0.02%). The 97% LOD was 1,318 IU/mL (95% CI 1298.4, 1322.3). Factors associated with LLV were younger age 18-30 vs. 51-64 years (OR 2.56 95% CI 2.19, 2.99), female vs. male sex (OR 1.32, 95% CI 1.18, 1.49), and advanced fibrosis stage F4 vs. F0-1 (OR 1.44, 95%CI 1.21, 1.69). Only the younger age group had a decreased relative sensitivity below 95% at 93.3%.

    CONCLUSIONS: In this global dataset, a test with an LOD of 1,318 IU/mL would identify 97% of viraemic HCV infections among almost all populations. This LOD will help guide manufacturers in the development of affordable POC diagnostics to expand HCV testing and linkage to care in LMICs.

    LAY SUMMARY: We created and analyzed a dataset from 12 countries with 66,640 participants with chronic hepatitis C virus infection. We determined that about 97% of those with viraemic infection had 1300 International Units/mL or more of circulating virus at the time of diagnosis. While current diagnostic tests can detect as little as 12 International Units/mL of virus, our findings suggest that increasing the level of detection closer to 1300 would maintain good test accuracy and will likely allow for more affordable portable tests to be developed for use in low and middle income countries.

    Neuroinflammation can damage the brain and plays a critical role in the pathophysiology of epilepsy. Tissue inhibitor of metalloproteinase 4 (TIMP4) is an inflammation-induced apoptosis and matrix turnover factor involved in several neuronal disorders and inflammatory diseases. Evidence has shown linkage disequilibrium between rs3755724 (-55C/T) of this gene with synapsin 2 (SYN2) rs3773364 and peroxisome proliferator-activated G receptor (PPARG) rs2920502 loci, which contribute to epilepsy in Caucasians. The aim of this study was to examine the association of these loci alone or their haplotypes with the risk of epilepsy in the Malaysian population. Genomic DNA of 1241 Malaysian Chinese, Indian, and Malay subjects (670 patients with epilepsy and 571 healthy individuals) was genotyped for the candidate loci by using the Sequenom MassArray method. Allele and genotype association of rs3755724 with susceptibility to epilepsy was significant in the Malaysian Chinese with focal epilepsy under codominant and dominant models (C vs. T: 1.5 (1.1-2.0), p=0.02; CT vs. TT: 1.8 (1.2-2.8), p=0.007 and 1.8 (1.2-2.7), p=0.006, respectively). The T allele and the TT genotype were more common in patients than in controls. No significant association was found between rs2920502 and rs3773364-rs3755724-rs2920502 haplotypes for susceptibility to epilepsy in each ethnicity. This study provides evidence that the promoter TIMP4 rs3755724 is a new focal epilepsy susceptibility variant that is plausibly involved in inflammation-induced seizures in Malaysian Chinese.

    Avian intestinal spirochaetosis causes problems including delayed onset of lay and wet litter in adult chickens, and results from colonization of the caecae/rectum with pathogenic intestinal spirochaetes (genus Brachyspira). Because avian intestinal spirochaetosis has not previously been studied in South East Asia, this investigation was undertaken in Malaysia. Faecal samples were collected from 25 farms and a questionnaire was administered. Brachyspira species were detected by polymerase chain reaction in 198 of 500 (39%) faecal samples from 20 (80%) farms, including 16 (94%) layer and four (50%) breeder farms. Pathogenic Brachyspira pilosicoli was identified in five (29%) layer and two (25%) breeder farms whilst pathogenic Brachyspira intermedia was detected in nine (53%) layer and one (12.5%) of the breeder farms. Twelve (80%) layer farms had egg production problems and 11 (92%) were positive for Brachyspira: three (25%) for B. pilosicoli and six (50%) for B. intermedia. Of three breeder farms with egg production problems, one was colonized with B. pilosicoli. Three of ten layer farms with wet litter were positive for B. pilosicoli and six for B. intermedia. Of four breeder farms with wet litter, one was colonized with B. pilosicoli and one with B. intermedia. No significant associations were found between colonization and reduced egg production or wet litter, perhaps because so many flocks were colonized. A significant association (P = 0.041) occurred between a high prevalence of colonization and faecal staining of eggs. There were significant positive associations between open-sided housing (P = 0.006), and flocks aged >40 weeks (P < 0.001) and colonization by pathogenic species.

    INTRODUCTION: Chlamydia trachomatis is one of the most common sexually transmitted diseases (STDs) globally. However, data on its prevalence and risk factors in Malaysia is still scarce.

    OBJECTIVE: We aimed to identify the prevalence and risk factors of genitourinary C.trachomatis infection among patients attending STD clinics in northern Peninsular Malaysia.

    METHODS: A hospital-based cross-sectional study was conducted in STD clinics of Hospital Pulau Pinang and Hospital Sultanah Bahiyah, Kedah from January to November 2014. Participants were individually interviewed using a structured data collection form followed by a physical examination and laboratory tests. Nucleic Acid Amplification Test (NAAT) was used to detect C.trachomatis infection. Analysis was carried out using SPSS Version 15.

    RESULTS: Eighty-three sexually active patients were enrolled, consisting of 51 males and 32 females. The median age was 28.0 years. In general, 32.5% patients were asymptomatic, the remaining presented with genital discharge (41.0%), genital warty lesion (25.3%), genital ulcer (13.3%), dysuria (13.3%), dyspareunia (2.4%), urine hesistancy (1.2%) and genital swelling (1.2%). The prevalence of genitourinary C.trachomatis infection was 21.7% in the study population; 17.6% in males and 28.1% in females. Among the infected females, 44.4% were pregnant. Of those infected 56.6% did not show any symptoms of genital infection, and 77.8% were aged between 18 and 30 years, of which most were females. Among newly diagnosed HIV patients, the prevalence was 14.3%. From multivariable logistic regression analysis, age under 28 years, being married and engagement in oral sex had significantly increased odds of C.trachomatis infection.

    CONCLUSIONS: C.trachomatis infection was common among patients attending STD clinics in northern Penisular Malaysia especially in the younger age groups. Majority of the infected patients were asymptomatic.

    Background:
    There is an escalation of frequency and magnitude of dengue epidemics in Malaysia, with a concomitant increase in patient hospitalization. Prolonged hospitalization (PH) due to dengue virus (DENV) infections causes considerable socioeconomic burden. Early identification of patients needing PH could optimize resource consumption and reduce health care costs. This study aims to identify clinicopathological factors present on admission that are associated with PH among patients with DENV infections.
    Methods:
    This study was conducted in a tertiary referral hospital in Southern Malaysia. Relevant clinical and laboratory data upon admission were retrieved from medical records of 253 consecutive DENV nonstructural protein 1 (NS1) antigen and PCR-positive hospitalized patients. The DENV serotype present in each patient was determined. Patients were stratified based on duration of hospital stay (<4 vs. ≥4 days). Data were analyzed using IBM® SPSS® 25.0. Multivariate logistic regression was performed to examine the association between PH and admission parameters.
    Results:
    Of 253 DENV hospitalized patients, 95 (37.5%) had PH (≥4 days). The mean duration of hospital stay was 3.43 ± 2.085 days (median = 3 days, interquartile range = 7 days). Diabetes mellitus (adjusted odds ratio [AOR] = 6.261, 95% confidence interval [CI] = 2.130-18.406, p = 0.001), DENV-2 serotype (AOR = 2.581, 95% CI = 1.179-5.650, p = 0.018), duration of fever ≤4 days (AOR = 2.423, 95% CI = 0.872-6.734, p = 0.09), and a shorter preadmission fever duration (AOR = 0.679, 95% CI = 0.481-0.957, p = 0.027) were independently associated with PH. However, PH was not found to be associated with symptoms on admission, secondary DENV infections or platelet count, hematocrit, or liver enzyme levels on admission.
    Conclusions:
    Early identification of these factors at presentation may alert clinicians to anticipate and recognize challenges in treating such patients, leading to more focused management plans that may shorten the duration of hospitalization.

    AIM: The rise in the prevalence of abdominal obesity (AO), in particular, has become a major concern as it contributes to diabetes, hypertension, high cholesterol, heart disease and certain types of cancer. The aim of this study is to determine the prevalence and associated factors of AO among older adults aged ≥60 years in Malaysia.

    METHODS: This was a nationwide cross-sectional study using two-stage stratified random sampling. In total, 3977 older adults aged ≥60 years were involved in this study. Socio-demography characteristics were obtained using self-administered questionnaire. AO was measured using waist circumference and classified according to the cut-off values of ≥90 cm for men and ≥80 cm for women based on the WHO recommendation. Descriptive and multiple logistic regression analysis using a complex sample design were performed for data analysis.

    RESULTS: Our findings showed that 2371 (67.3%) older adults had AO. Older adults who were from urban areas (69.7%), of women (78.4%), married (66.7%), with tertiary education (73.6%) and unemployed (70.9%) had the highest prevalence of AO. Those from urban areas (adjusted odds ratio [aOR] = 1.29), women (aOR = 3.12), unemployed (aOR = 1.14), diagnosed with hypertension (aOR = 1.56) and diabetes mellitus (aOR = 2.08) were also significantly associated with a higher risk of AO.

    CONCLUSIONS: This study identified several risk factors that are associated with AO among older adults in Malaysia. Such information is important and needed to improve the healthcare system systematically, enable nutrition screening and appropriate intervention to combat the growing AO in Malaysia.

    Blood pressure has a significant effect on retinal arterioles. There are few data on whether this effect varies by race/ethnicity. We examined the relationship of blood pressure and retinal vascular caliber in a multi-ethnic Asian population. The study is population-based and cross sectional in design. A total of 3749 Chinese, Malay and Indian participants aged > or =24 years residing in Singapore were included in the study. Retinal vascular caliber was measured using a computer program from digital retinal photographs. The associations of retinal vascular caliber with blood pressure and hypertension in each racial/ethnic group were analyzed. The main outcome measures are retinal arteriolar caliber and venular caliber. The results show that retinal arterioles were narrower in persons with uncontrolled/untreated hypertension (140.0 microm) as compared with persons with controlled hypertension (142.1 microm, P=0.0001) and those with no hypertension (146.0 microm, P<0.0001). On controlling for age, gender, body mass index, lipids and smoking, each 10 mm Hg increase in mean arterial blood pressure was associated with a 3.1 microm decrease in arteriolar caliber (P<0.0001), with a similar magnitude seen in all three racial/ethnic groups: 3.1 microm in Chinese, 2.8 microm in Malays and 3.2 microm in Indians (P<0.0001 for all). Each 10 mm Hg increase in mean arterial blood pressure was associated with a 1.8 microm increase in venular caliber (P<0.0001); furthermore, the magnitude of this effect was similar across the three racial/ethnic groups. The effect of blood pressure on the retinal vasculature was similar across three major racial/ethnic groups in Asia.
