    Background: Leptospirosis is a zoonotic disease that infects human and livestock which causes economic losses to the farmers. It has been reported as one of the causes of reproductive failure in cattle and other ruminants, determining abortions, stillbirth, weak newborns, and decrease in their growth rate and milk production.

    Aim: The objectives of this study were to determine the leptospirosis seroprevalence and to identify the predominant infecting serovars among cattle.

    Materials and Methods: A cross-sectional study involving 420 cattle from six randomly selected districts in Kelantan was conducted. A serological test using the microscopic agglutination test was conducted in the Institute of Medical Research with a cutoff titer for seropositivity of ≥1:100.

    Results: The overall prevalence of leptospirosis seropositivity among cattle in this study was 81.7% (95% confidence interval: 63.5, 80.1). The most common reaction obtained with the sera tested was from the serovar Sarawak with 78.8%.

    Conclusion: A high seroprevalence of leptospiral antibodies was found among cattle in Northeastern Malaysia. These findings urge that more studies are required to determine the reasons for the high seroprevalence among the cattle along with its transmission and pathogenicity of the local serovar Sarawak.

    The teaching profession is an occupation at high risk for stress. This research attempted to determine the prevalence of stress and the associated factors contributing to stress among teachers in Malaysia. A cross-sectional study was conducted on 580 secondary school teachers in Kota Bharu District. The instrument used to carry out the study was adopted and modified from the Depression, Anxiety and Stress Scale (DASS 21) and Job Content Questionnaire (JCQ). The questionnaire consisted of two parts: Part I consisting non-job factors (socio-demographic characteristics) and Part II consisting of psychosocial factors contributing to stress. Simple and multiple linear regression analysis were carried out. The prevalence of stress was reported as 34.0%. Seventeen point four percent of teachers experienced mild stress. Age, duration of work and psychological job demands were significantly associated with stress level. This study indicates job-related factors did not contribute much to stress among secondary school teachers. Non-job-related factors should be further studied to determine methods for stress reduction in teachers in Malaysia.

    This study was conducted to assess the reliability and construct validity of the Malay version of Job Content Questionnaire (JCQ) among secondary school teachers in Kota Bharu, Kelantan. A total of 68 teachers consented to participate in the study and were administered the Malay version of JCQ. Reliability was determined using Cronbach's alpha for internal consistency whilst construct validity was assessed using factor analysis. The results indicated that Cronbach's alpha coefficients revealed decision latitude (0.75), psychological job demand (0.50) and social support (0.84). Factor analysis showed three meaningful common factors that could explain the construct of Karasek's demand-control-social support model. The study suggests the JCQ scales are reliable and valid tools for assessing job stress in school teachers.

    A descriptive study was conducted on premarital HIV screening programme in Johor over a three year period. HIV screenings were done at government clinics and confirmed by accredited laboratories. As a result, 123 new HIV cases were detected (0.17%) from 74,210 respondents. In 2004, 24 cases (64.9%) advanced to marriage (n = 37) after they underwent counselling and six of them married among themselves. Positivity rate from this programme (0.17%) is higher than antenatal screening (0.05%). Despite the implementation of the premarital HIV screening programme, marriage application in Johor rose 2.8% in 2004 compared with 2002. This programme had partly contributed to public awareness against HIV and provides another option in early detection of the disease.

    We analyzed the characteristics of patients presenting with acute pancreatitis to our unit. A total of 71 patients were admitted to the Surgical Department at University Kebangsaan Malaysia (UKM) over a period of seven years, between January 1990 to December 1996 with acute pancreatitis. There was a fourfold increase in incidence of acute pancreatitis in our hospital from January 1990 to December 1996. The commonest identifiable aetiology was gallstones followed by alcohol. There were two deaths. We conclude that acute pancreatitis is increasingly being diagnosed in our local population. This may be due to either greater awareness or changes in lifestyle of the population.

    Intrahepatic stones remain a major source of morbidity and mortality. With improving techniques in hepatobiliary surgery, the management and the outcome of intrahepatic calculi is reviewed. Forty-nine cases referred from all over Malaysia between January 1993 to June 1996 were analyzed retrospectively. There were thirty-two females and seventeen males. The median age was 46 years. Biliary diseases encountered in association with intrahepatic calculi included benign strictures (n = 14), ascariasis (n = 3), cholangiocarcinoma (n = 1), Caroli's disease (n = 1), and thalassaemia, (n = 1), fifty-six percent of stones were located in both the intrahepatic ducts while 34% were found in the left intrahepatic duct. Thirty-one patients underwent common bile duct exploration either alone or in combination with liver resection or bilioenteric anastomosis. Despite the various combinations of surgical and non-surgical intervention 28 (57.1%) patients had residual stones. Despite the availability of newer techniques in hepatobiliary surgery, residual stones were common, resulting in higher treatment costs.

    INTRODUCTION: Diabetic peripheral neuropathy (DPN) is one of the most prevalent chronic complications of diabetes mellitus (DM) that can significantly result in disability and impaired quality of life. The DPN of the foot has been extensively studied in diabetes care. Nevertheless, the DPN of hand has been the road less taken in research and clinical practice. Thus, a scoping review was conducted to identify all available standardized hand assessments which have been used, developed, or tested in individuals with DM.

    MATERIALS AND METHODS: This scoping review was reported in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Studies were identified through searches of five databases: Cochrane, Scopus, ProQuest, MEDLINE, and Web of Science (WoS).

    RESULTS: Of the 294 articles initially identified, 20 studies were included and analysed thematically after removing duplicates. The majority of these assessments measure body function and structure such as grip and pinch strength while the rest are measuring the activity and participation domain. Most of the hand assessments were performancebased measurements. It is suggestible to employ both types of assessments to obtain a comprehensive understanding of hand conditions in individuals with DM. While some validated hand assessments were identified, only the Duruöz Hand Index (DHI) has been validated as a reliable tool specifically for evaluating hand function in individuals with DM.

    CONCLUSION: There is a need to evaluate the measurement properties of existing instruments for assessing the hand function in individuals with DM, or to develop hand assessments specifically for the DM population. This scoping review was forging a new path, by discovering diabetes care through the utilisation of hand assessments.

    INTRODUCTION: This study aimed to determine the predictors of quality of life (QOL) among persons with paraplegic spinal cord injury (SCI) after discharge from the hospital to the community in Pakistan, based on the International Classification of Functioning (ICF) components, including participation, impairments of body function/structures, personal factors, and environmental factors.

    MATERIALS AND METHODS: A cross-sectional study was conducted with, one hundred and forty individuals with paraplegic SCI, who met the inclusion and exclusion criteria and attended an outpatient rehabilitation clinic. The impairment of body function/structures of participants was assessed using the American Spinal Injury Association (ASIA) Scale, which classified them as A, B, C, D, or E. A set of questionnaire survey forms was used to collect sociodemographic information, occupational participation, environmental factors, and QOL by using a demographic questionnaire, World Health Organization Disability Assessment Schedule 2.0 (WHODAS-II), Craig Hospital Inventory of Environmental Factors (CHIEF) scale and World Health Organization Quality of Life (WHOQOL) BREF form respectively.

    RESULTS: The results showed that occupational participation was the strongest predictor of QOL among persons with paraplegic SCI (β=-0.586, p<0.001). In the second step, variables representing body function/structure factors (ASIA-A, B, C, D, E) were added, and the overall model explained 40.7% of the variance in QOL. In the third step, personal factors (age groups, gender, marital status, level of education, and rehabilitation duration) were added, and the overall model explained 51.4% of the variance in QOL. In the final step, environmental factors (CHIEF 12 Items scale) were added, but they did not significantly explain the model.

    CONCLUSION: The findings suggest that occupational participation was found to be the most significant predictor of QOL among individuals with paraplegic SCI. Body function/structure factors, personal factors, and environmental factors were also significant predictors, but to a lesser extent. The findings of this study can inform healthcare professionals and policymakers in developing interventions and, policies targeting occupational participation, and personal factors that may be effective to improve the QOL of individuals with paraplegic SCI in Pakistan.

    The purpose of this study was to determine the sawmill workers' knowledge, attitude and practice (KAP) in relation to noise-induced hearing loss (NIHL). A cross-sectional study was conducted involving 83 workers from 3 factories in Kota Bharu, Kelantan. Questionnaires were distributed to obtain the socio-demography, knowledge, attitude and practice level in relation to noise-induced hearing loss (NIHL). The weak areas identified in the knowledge section were treatment aspects (15.5%), signs and symptoms of NIHL (20.2%) and risk factors (31%). As for attitude; the prevention aspects were the lowest (25.3%), followed by risk taking attitude (26.2%), and causes of hearing loss (42.1%). Overall, the practice was not encouraging at all. It is important to have an education program to raise workers' awareness and to improve their attitude and practices towards noise-induced hearing loss.

    BACKGROUND: Workplace violence prevention initiatives are undeniably lacking in healthcare facilities. The aim of this study was to validate a newly developed questionnaire and assess employers' perceptions and practices towards workplace violence prevention at healthcare facilities.

    METHODS: A cross-sectional study was conducted from October 2021 to November 2021 by recruiting 333 employers at healthcare facilities in Kelantan, Malaysia. The original draft of the Malay version of the questionnaire comprised 62 items constructed under two domains (perception and practice). A confirmatory factor analysis was conducted to evaluate construct validity and internal consistency using R software.

    RESULTS: The final model for the perception and practice domain of the questionnaire consisted of 13 factors and 56 items. The factor loadings for all items were above 0.6. The fit indices used for confirmatory factor analysis in the final model were as follows: χ2 = 2092.6 (P < 0.001), standardised root mean squared residual (SRMR) = 0.053, root mean square error of approximation (RMSEA) = 0.042, comparative fit index (CFI) = 0.928 and Tucker Lewis index (TLI) = 0.920. The construct reliability for all factors was reliable, with Raykov's rho coefficients above 0.70.

    CONCLUSION: The newly developed questionnaire demonstrated excellent psychometric properties and adequate validity and reliability, confirming that this instrument is reliable and valuable for evaluating employers' perceptions and practices towards workplace violence prevention at healthcare facilities.

    Data on the prevalence and risk factors of low back pain (LBP) in Malaysia remain unclear as they are currently limited to specific settings and occupational groups. Therefore, this study aims to determine the prevalence and risk factors of low back pain in Malaysia. In this scoping review, we had systematically searched PubMed, Scopus, ScienceDirect and Google Scholar from January 2016 to April 2020. In addition, we had included cross-sectional studies on LBP in Malaysia. Studies without data on the prevalence and risk factors were excluded. The settings, population, design, sample size, evaluation methods, prevalence and risk factors of the studies were summarised. The literature search identified 435 potentially eligible studies; of these, 21 had met the inclusion criteria. The prevalence of LBP in Malaysia among various types of the population had ranged from 12.4% to 84.6%. Among the various types of occupation, the prevalence of LBP was the highest among nurses (67.9%), followed by drivers (65.7%). In addition, age, gender, body mass index (BMI), lifting heavy objects, working posture, lifestyle, working hours and mental health were identified as the risk factors of LBP in Malaysia. The current evidence suggests that LBP is a serious health problem among several occupational groups in Malaysia. Therefore, it is crucial to implement the correct interventions for the prevention of LBP among these groups.

    This qualitative study aimed to explore the misconceptions, knowledge gaps and constructs of leptospirosis among 72 respondents from rural and urban districts in two states of Malaysia. We conducted focus group discussions and data were examined using thematic analyses. The layman term of 'rat urine disease' contributed the most to the misconceptions regarding leptospirosis. There were gaps in the knowledge among urban and rural respondents in the two states, with the majority of subjects demonstrating a poor understanding of the disease. Construction of knowledge about leptospirosis relied mostly on the information provided by mass and social media; reading materials; word-of-mouth publicity; observations; experiences; and knowledge sharing among families, friends, and communities. The study findings may provide the foundation for the development of educational materials that may reduce the gaps in knowledge, and thereby improve health literacy and enhance preventive health behaviours for avoiding leptospirosis.

    Phytochemical studies on the leaves and trunk bark of Garcinia cantleyana yielded five caged-xanthonoids including one tetra- and four tri-prenylated xanthones, cantleyanone A (1), 7-hydroxyforbesione (2) and cantleyanones B-D (4-6), as well as a simple xanthone, 4-(1,1-dimethylprop-2-enyl)-1,3,5,8-tetrahydroxyxanthone (3). Eight other known compounds, deoxygaudichaudione A, gaudichaudione H, friedelin, garbogiol, macranthol, glutin-5-en-3beta-ol, and a mixture of sitosterol and stigmasterol were also isolated. Their structures were elucidated by means of spectroscopic data and comparison of their NMR data with literature values. Significant cytotoxicity against MDA-MB-231, CaOV-3, MCF-7 and HeLa cancer cell-lines was demonstrated by cantleyanones B-D, 7-hydroxyforbesione, deoxygaudichaudione A and macranthol, with IC(50) values ranging from 0.22 to 17.17 microg/ml.

    Noise is known to be one of the environmental and occupational hazards listed in the Factory and Machinery Act 1967. Quarries with loud deafening sounds from trucks and machineries pose the risk of noise-induced hearing loss to workers. This study was designed to assess the knowledge, attitude and practice towards noise-induced hearing loss and to determine the prevalence of noise-induced hearing loss and its associated factors among quarry workers in a north-eastern state of Malaysia.

    L-Glutamate plays a crucial role in neuronal cell death, which is known to be associated with various neurodegenerative diseases, such as Alzheimer's, Parkinson's, and Huntington's diseases. In this study, we investigated the protective effects of biochanin A, a phytoestrogen compound found mainly in Trifolium pratense, against L-glutamate-induced cytotoxicity in a PC12 cell line. Exposure of the cells to 10 mM L-glutamate was found to significantly increase cell viability loss and apoptosis, whereas pretreatment with various concentrations of biochanin A attenuated the cytotoxic effects of L-glutamate. Specifically, the pretreatment led to not only decreases in the release of lactate dehydrogenase, the number of apoptotic cells, and the activity of caspase-3 but also an increase in the total glutathione level in the L-glutamate-treated PC12 cells. These results indicate that biochanin A may be able to exert neuroprotective effects against L-glutamate-induced cytotoxicity. Furthermore, our findings also imply that biochanin A may act as an antiapoptotic agent in order to perform its protective function.

    Objective: To evaluate the effect of a new application method of bulk-fill flowable composite resin material on bond-strength, nanoleakage, and mechanical properties of dentine bonding agents.

    MATERIALS AND METHODS: Sound extracted human molars were randomly divided into: manufacturer's instructions (MI), manual blend 2 mm (MB2), and manual blend 4 mm (MB4). Occlusal enamel was removed and flattened, dentin surfaces were bonded by Prime & Bond universal (Dentsply and Optibond FL, Kerr). For the MI group, adhesives were applied following the manufacturer's instructions then light-cured. For MB groups, SDR flow+ bulk-fill flowable composite resin was applied in 2- or 4-mm increment then manually rubbed by a micro brush for 15 s with uncured dentine bonding agents and the mixture was light-cured. Composite buildup was fabricated incrementally using Ceram.X One, Dentsply nanohybrid composite resin restorative material. After 24-h water storage, the teeth were sectioned to obtain beams of about 0.8 mm2 for 24-h and thermocycled micro-tensile bond strength at 0.5 mm/min crosshead speed. Degree of conversion was evaluated with micro-Raman spectroscopy. Contraction gaps at 24 h after polymerization were evaluated and atomic force microscopy (AFM) nano-indentation processes were undertaken for measuring the hardness across the interface. Depth of resin penetration was studied using a scanning electron microscope (SEM). Bond strength data was expressed using two-way ANOVA followed by Tukey's test. Nanoindentation hardness was separately analyzed using one-way ANOVA.

    RESULTS: Factors "storage F = 6.3" and "application F = 30.11" significantly affected the bond strength to dentine. For Optibond FL, no significant difference in nanoleakage was found in MI/MB4 groups between baseline and aged specimens; significant difference in nanoleakage score was observed in MB2 groups. Confocal microscopy analysis showed MB2 Optibond FL and Prime & Bond universal specimens diffusing within the dentine. Contraction gap was significantly reduced in MB2 specimens in both adhesive systems. Degree of conversion (DC) of the MB2 specimens were numerically more compared to MS1 in both adhesive systems.

    CONCLUSION: Present study suggests that the new co-blend technique might have a positive effect on bond strengths of etch-and-rinse adhesives to dentine.

    The antioxidant, radical-scavenging, anti-inflammatory, cytotoxic and antibacterial activities of methanolic extracts of seven Hedyotisspecies were investigated. The antioxidant activity was evaluated by the ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods while the radical scavenging activity was measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The anti-inflammatory activity related to NO inhibition of the plant extracts was measured by the Griess assay while cytotoxicity were measured by the MTT assay against CEM-SS cell line. The antibacterial bioassay (against 4 bacteria, i.e. Bacillus subtilis B28 (mutant), Bacillus subtilis B29 (wild-type), Pseudomonas aeruginosa UI 60690 and methicillin resistant Staphylococcus aureus, (MRSA) was also carried out using the disc-diffusion method. All tested extracts exhibited very strong antioxidant properties when compared to Vitamin E (alpha-tocopherol) with percent inhibition of 89-98% in the FTC and 60-95% in the TBA assays. In the DPPH method, H. herbacea exhibited the strongest radical scavenging activity with an IC50 value of 32 microg/ml. The results from the Griess assay showed that the tested extracts are weak inhibitors of NO synthase. However, all tested extracts exhibited moderate cytotoxic properties against CEM-SS cell line giving CD50 values in the range of 21-41 microg/ml. In the antibacterial bioassay, the stems and the roots of H. capitellata showed moderate activity against the 4 tested bacteria while the leaves showed moderate activity towards B. subtilis B28, MRSA and P. aeruginosa only. The roots of H. dichotoma showed strong antibacterial activity against all 4 bacteria. All other extracts did not exhibit any antibacterial activity.

    BACKGROUND: The optimal duration of infusion set use to prevent life-threatening catheter-related bloodstream infection (CRBSI) is unclear. We aimed to compare the effectiveness and costs of 7-day (intervention) versus 4-day (control) infusion set replacement to prevent CRBSI in patients with central venous access devices (tunnelled cuffed, non-tunnelled, peripherally inserted, and totally implanted) and peripheral arterial catheters.

    METHODS: We did a randomised, controlled, assessor-masked trial at ten Australian hospitals. Our hypothesis was CRBSI equivalence for central venous access devices and non-inferiority for peripheral arterial catheters (both 2% margin). Adults and children with expected greater than 24 h central venous access device-peripheral arterial catheter use were randomly assigned (1:1; stratified by hospital, catheter type, and intensive care unit or ward) by a centralised, web-based service (concealed before allocation) to infusion set replacement every 7 days, or 4 days. This included crystalloids, non-lipid parenteral nutrition, and medication infusions. Patients and clinicians were not masked, but the primary outcome (CRBSI) was adjudicated by masked infectious diseases physicians. The analysis was modified intention to treat (mITT). This study is registered with the Australian New Zealand Clinical Trials Registry ACTRN12610000505000 and is complete.

    FINDINGS: Between May 30, 2011, and Dec, 9, 2016, from 6007 patients assessed, we assigned 2944 patients to 7-day (n=1463) or 4-day (n=1481) infusion set replacement, with 2941 in the mITT analysis. For central venous access devices, 20 (1·78%) of 1124 patients (7-day group) and 16 (1·46%) of 1097 patients (4-day group) had CRBSI (absolute risk difference [ARD] 0·32%, 95% CI -0·73 to 1·37). For peripheral arterial catheters, one (0·28%) of 357 patients in the 7-day group and none of 363 patients in the 4-day group had CRBSI (ARD 0·28%, -0·27% to 0·83%). There were no treatment-related adverse events.

    INTERPRETATION: Infusion set use can be safely extended to 7 days with resultant cost and workload reductions.
