METHODS: The ADR reports recorded between 2000 and 2017 were retrospectively analysed to identify hepatic ADR reports. The trend and characteristics of hepatic ADR cases were described. Multivariate disproportionality analysis of the causative agents was performed to generate signals of hepatic ADRs.
RESULTS: A total of 2090 hepatic ADRs (1.77% of all ADRs) were reported with mortality rate of 12.7% among cases with known clinical outcomes. The incidence of hepatic ADR reporting in Malaysia increased significantly over 18 years from 0.26 to 9.45 per million population (P Malaysia, with antituberculosis drugs, systemic antibacterials, and TCM/HDS being the most common causative agents reported. Most TCM/HDS reported to be associated with hepatic ADR were not registered with the authorities.
METHODS: This cross-sectional study was conducted between August 2020 and January 2021, in the Infectious Disease clinic and ward. One hundred ninety-one patients were recruited via convenience sampling. Patients' sociodemographic were obtained, followed by Depression, Anxiety, Stress Scale -21 (DASS-21), Multidimensional Scale of Perceived Social Support (MSPSS), and M.I.N.I. international neuropsychiatric interview (M.I.N.I.) The cut off DASS-21 point for depression is ≥5, for anxiety, ≥ 4. Mann-Whitney U and Chi square test were used to analyse the association between variables, and logistic regression to find predictability.
RESULTS: Of the 191 participants, 89.5% outpatient, mean age 40 years (SD 0.742), 91.1% male, 65.4% single, 71.2% working, 46.1% Malaysian Chinese, 59.8% non- heterosexual, mean 6 years of being HIV positive; mean CD4 count 449/μL; mean viral load 116,690 (median = 20). 85.9% were taking antiretroviral therapy. The prevalence of depression was 35.1% (n = 67); anxiety was 42.9% (n = 82). Regression analysis revealed anxiety and stress increased odds of depression by 3.8 times (p = .001) and 12 times (p < .001) respectively. Those 40 years old and younger had 2.3 times odds of anxiety (p = .048). Increased social support from friends increased odds of anxiety by 1.7 times (p = .018). Depression and stress increased odds of anxiety by 4.4 times (p = .001) and 3.7 times (p = .008) respectively.
CONCLUSIONS: Depression and anxiety among people with HIV is often under-recognised. Early identification and treatment of the mental illness is warranted. Screening with DASS-21 is useful to detect depression in patients with HIV.
METHODS: We collected classroom dust from 24 junior high schools in three geographically distanced areas in Malaysia (Johor Bahru, Terengganu and Penang), and conducted culture-independent high-throughput microbiome and untargeted metabolomics/chemical profiling.
RESULTS: 1290 students were surveyed for asthma symptoms (wheeze). In each centre, we found significant variation in the prevalence of wheeze among schools, which could be explained by personal characteristics and air pollutants. Large-scale microbial variations were observed between the three centres; the potential protective bacteria were mainly from phyla Actinobacteria in Johor Bahru, Cyanobacteria in Terengganu and Proteobacteria in Penang. In total, 2633 metabolites and chemicals were characterised. Many metabolites were enriched in low-wheeze schools, including plant secondary metabolites flavonoids/isoflavonoids (isoliquiritigenin, formononetin, astragalin), indole and derivatives (indole, serotonin, 1H-indole-3-carboxaldehyde), and others (biotin, chavicol). A neural network analysis showed that the indole derivatives were co-occurring with the potential protective microbial taxa, including Actinomycetospora, Fischerella and Truepera, suggesting these microorganisms may pose health effects by releasing indole metabolites. A few synthetic chemicals were enriched in high-wheeze schools, including pesticides (2(3H)-benzothiazolethione), fragrances (2-aminobenzoic acid, isovaleric acid), detergents and plastics (phthalic acid), and industrial materials (4,4-sulfonyldiphenol).
CONCLUSIONS: This is the first association study between high-throughput indoor chemical profiling and asthma symptoms. The consistent results from the three centres indicate that indoor metabolites/chemicals could be a better indicator than the indoor microbiome for environmental and health assessments, providing new insights for asthma prediction, prevention and control.
METHODS: Individuals of An. balabacensis were collected in the field in Ranau district, Sabah to establish a laboratory colony. Induced mating was used, and the life history parameters of the progeny were recorded. The age-stage, two-sex life table approach was used in the analysis. The culture conditions in the laboratory were 9 h light:15 h dark, mean temperature 25.7 °C ± 0.05 and relative humidity 75.8% ± 0.31.
RESULTS: The eggs hatched within 2 days, and the larval stage lasted for 10.5 days in total, with duration of instar stages I, II, III and IV of 2.3, 3.7, 2.3, 2.2 days, respectively. The maximum total fecundity was 729 for one particular female, while the maximum female age-specific mean fecundity (mx) was 142 at age 59 days. The gross reproductive rate or number of offspring per individual was about 102. On average, each female laid 1.81 ± 0.19 (range 1-7) batches of eggs, with 63% of the females producing only one batch; only one female laid six batches, while one other laid seven. Each batch comprised 159 ± 17.1 eggs (range 5-224) and the female ratio of offspring was 0.28 ± 0.06. The intrinsic rate of increase, finite rate of increase, net reproductive rate, mean generation time and doubling time were, respectively, 0.12 ± 0.01 day-1, 1.12 ± 0.01 day-1, 46.2 ± 14.97, 33.02 ± 1.85 and 5.97 days.
CONCLUSIONS: Both the net reproductive rate and intrinsic rate of increase of An. balabacensis are lower than those of other species in published studies. Our results can be used to improve models of P. knowlesi transmission and to set a baseline for assessing the impacts of environmental change on malaria dynamics. Furthermore, incorporating these population parameters of An. balabacensis into spatial and temporal models on the transmission of P. knowlesi would provide better insight and increase the accuracy of epidemiological forecasting.
OBJECTIVE: The purpose of the present study was to investigate the effects of differences in social demographic factors and domain-specific sedentary behaviour and health-related quality of life by age in Japanese living overseas.
METHODS: We surveyed 109 participants by self-entry questionnaire for social demographic factors and domain-specific sedentary behaviour by life scenario and by Short Form-36 (SF-36) for healthrelated quality of life. The subjects were divided into the ≥65 years group and <65 years group.
RESULTS: Significant differences were noted in age, employment, alcohol intake, and marital status between the groups, whereas none were noted for transportation, driving, television viewing, and smartphone/personal computer use. Work time and total sitting time of sedentary behaviour were higher, and leisure-time activity and SF-36 Mental Component Score for health-related quality of life were lower in the <65 years group.
CONCLUSION: By assessing differences in social demographic factors and discouraging sedentary behaviour, sitting time in overseas-dwelling Japanese residents may be reduced, and effective strategies to improve health-related quality of life can be developed to combat such behaviour.
PURPOSE: With the rising number of older people in Malaysia, it is envisaged that the number of fragility hip fractures would also increase. The objective of this study was to determine patient characteristics and long-term outcomes of hip fracture in older individuals at a teaching hospital in Malaysia.
METHODS: This was a prospective observational study which included consecutive patients aged ≥ 65 years old admitted to the orthopedic ward with acute hip fractures between March 2016 and August 2018. Patient socio-demographic details, comorbidities, pre-fracture mobility status, fracture type, operation and anesthesia procedure, and length of stay were recorded. Post-fracture mobility status was identified at 6 months. Cox proportional hazard analysis was used to assess the risk of death in all patients.
RESULTS: 310 patients (70% women) with the mean age of 79.89 years (SD 7.24) were recruited during the study period. Of these, 284 patients (91.6%) underwent surgical intervention with a median time to surgery of 5 days (IQR 3-8) days. 60.4% of patients who underwent hip fracture surgery did not recover to their pre-fracture mobility status. One year mortality rate was 20.1% post hip fracture surgery. The independent predictor of mortality included advanced age (hazard ratio, HR = 1.05, 95% CI = 1.01-1.08; p = 0.01), dependency on activities of daily living (HR = 2.08, 95% CI = 1.26-3.45; p = 0.01), and longer length of hospitalization (HR = 1.02, 95% CI = 1.01-1.04; p
MATERIALS AND METHODS: A cross-sectional study was performed involving 331 subjects between 45-90 years recruited at a health screening programme. Sociodemographic and clinical characteristics were recorded. Biochemical analyses on fasting blood samples and dual energy X-ray absorptiometry scan to determine bone mineral density (BMD) were performed.
RESULTS: Increased waist circumference (WC) was protective for abnormal BMD status (osteopenia and OP). Males with increased high-density lipoprotein cholesterol (HDL) were more likely to be osteoporotic. WC, fasting blood glucose (FBG) and triglyceride (TG) were positively associated with BMD at all sites but was gender specific. In contrast, WC was negatively associated with trabecular bone score (TBS) for females but this association became attenuated when adjusted for fat percentage. HDL and MetS were negatively and positively associated with BMD, respectively in males.
CONCLUSION: The cardiovascular risk factors of raised WC, FBG, TG and low HDL were significantly associated with increased BMD with skeletal site and gender specific differences after adjusting for confounders. However, a higher WC was associated with a weaker skeletal microstructure reflected by lower TBS in females driven by fat percentage. A higher BMD was demonstrated among MetS individuals. These findings suggest that adiposity may have a protective effect on BMD.
METHODS AND ANALYSIS: The implementation research logic model guided the development of the study and implementation outcome measures were informed by the 'Reach, Effectiveness, Adoption, Implementation and Maintenance' (RE-AIM) framework. This CRC screening intervention for Malaysia uses home-testing and digital, small media, communication to improve CRC screening uptake. A sample of 780 people aged 50-75 years living in Segamat district, Malaysia, will be selected randomly from the South East Asia Community Observatory (SEACO) database. Participants will receive a screening pack as well as a WhatsApp video of a local doctor to undertake a stool test safely and to send a photo of the test result to a confidential mobile number. SEACO staff will inform participants of their result. Quantitative data about follow-up clinic attendance, subsequent hospital tests and outcomes will be collected. Logistic regression will be used to investigate variables that influence screening completion and we will conduct a budget impact-analysis of the intervention and its implementation. Qualitative data about intervention implementation from the perspective of participants and stakeholders will be analysed thematically.

METHODS: This retrospective, observational, population-based study involved all children with KD registered in Johor Kawasaki Clinical Registry over 10 years (January 2010 and December 2019). The prevalence of delayed diagnosis and its trend over time was calculated. Multivariable binary logistic regression was used to identify the independent risk factors for delayed diagnosis.
RESULTS: There were 556 cases of KD, with 28% having incomplete criteria, 11% atypical presentation, while 10% developed a coronary aneurysm. The overall prevalence of delayed diagnosis was 9.9% (95% confidence interval (CI): 7.6-12.7%). There was a statistically significant decrease in delayed diagnosis over time (P = 0.008), with the latest rate of 4.6%. The majority of delayed diagnoses were due to failure to diagnose the disease during the initial consultation. Independent risk factors for delayed diagnosis were children older than 1 year, diagnosis before 2015, atypical presentation, and incomplete KD, with adjusted odds ratios (ORs) of 2.7, 2.3, 4.3, and 3.6, respectively. Compared to early diagnosis of KD, delayed diagnosis was significantly associated with coronary aneurysms (27.3% vs. 8.2%, P < 0.001, OR 4.2, [95% CI: 2.1-8.3]).
CONCLUSIONS: One-tenth of cases of KD were diagnosed late, but it has improved over time. Children > 1 year, presenting with atypical presentation, and incomplete criteria are associated with late diagnosis.
