    Termite nests have long been suggested to be good indicators of groundwater but only a few studies are available to demonstrate the relationship between the two. This study therefore aims at investigating the most favourable spots for locating groundwater structures on a small parcel of land with conspicuous termite activity. To achieve this, geophysical soundings using the renowned vertical electrical sounding (VES) technique was carried out on the gridded study area. A total of nine VESs with one at the foot of a termitarium were conducted. The VES results were interpreted and assessed via two different techniques: (1) physical evaluation as performed by drillers in the field and (2) integration of primary and secondary geoelectrical parameters in a geographic information system (GIS). The result of the physical evaluation indicated a clear case of subjectivity in the interpretation but was consistent with the choice of VES points 1 and 6 (termitarium location) as being the most prospective points to be considered for drilling. Similarly, the integration of the geoelectrical parameters led to the mapping of the most prospective groundwater portion of the study area with the termitarium chiefly in the center of the most suitable region. This shows that termitaria are valuable landscape features that can be employed as biomarkers in the search of groundwater.

    While the role of medical and nutrition factors on glycemic control among adults with type 2 diabetes mellitus (T2DM) has been well-established, the association between health literacy (H.L.) and glycemic control is inconsistent. This study aims to determine the association of H.L. and nutritional status assessments with glycemic control in adults with type 2 diabetes mellitus. A total of 280 T2DM respondents (mean (SD) age = 49.7 (10.3) years, Glycated hemoglobin (HbA1c) = 9.9 (2.6) %, and Body Mass Index = 32.7 (15.1) kg/m2) were included in this study. A short-form Test of Functional Health Literacy in Adults (S-TOFHLA) assessed the H.L. levels. Nutritional status assessments included client history, glycemic control, anthropometric, and biochemical data. The mean (S.D.) H.L. score was 45.7 (24.6), with 56% of the respondents had inadequate H.L. Inadequate H.L. was more common among those females; housewives, low education, received oral antidiabetic therapy, and shorter diabetes duration. Respondents with inadequate H.L. were significantly older and had higher HbA1c than those with marginal and adequate H.L. Meanwhile, respondents with inadequate and marginal H.L. levels had significantly higher total cholesterol, LDL-cholesterol, and systolic blood pressure than the respondents with adequate H.L. Low H.L. scores, self-employment status, received dual antidiabetic therapy (insulin with oral agents), received insulin alone, and had higher fasting blood glucose explained about 21% of the total variation in HbA1c (adjusted R2 = 0.21; p < 0.001). Respondents with inadequate H.L. had poor glycemic control. The H.L. scores, together with nutritional status assessments, were the factors that predicted poor glycemic control among adults with T2DM.

    Introduction: Community pharmacist's knowledge about the uses of herbal medicines and its adverse drug reactions reporting can contribute in better therapeutic outcomes and patient safety. Objectives: To evaluate community pharmacists' knowledge about the use of herbal medicines and its adverse drug reactions reporting in Kedah state, Malaysia.

    Methods: A cross-sectional, questionnaire-based study was conducted among 103 pharmacists from 74 different community pharmacies to assess their knowledge about the use of herbal medicines and its adverse drug reaction reporting by using a pre-validate knowledge questionnaire consisting of 12 questions related to it. The pharmacists' responses were measured at a 3-point Likert scale (Poor=1, Moderate=2, and Good=3) and data was entered in SPSS version 22. The minimum and maximum possible scores for knowledge questionnaires were 12 and 36 respectively. Quantitative data was analyzed by using One Way ANOVA and Paired t-test whereas Chi-square and Fisher exact test were used for qualitative data analysis. A p-value of less than 0.05 was considered statistically significant for all the analyses.

    Results: About 92% of the pharmacist had good knowledge regarding the use of herbal medicines and its adverse drug reaction reporting with a mean knowledge score of 32.88±3.16. One-way ANOVA determined a significant difference of employment setting (p<0.043) and years of experience (<0.008) with mean knowledge scores of Pharmacists. Pharmacists' knowledge was significantly associated with their years of experience with the Chi-square test.

    Conclusion: Pharmacists exhibit good knowledge regarding the use of herbal medicines and its adverse drug reaction reporting. However, with an increasing trend of herbal medicine use and its adverse drug reaction reporting it recalls the empowerment of experienced pharmacists with training programs in this area for better clinical outcomes.

    Background: Chronic pain is a growing public health concern affecting 1.5 million people in Canada. In particular, it is a concern among the expanding immigrant population, because immigrant groups report higher pain intensity than non-immigrants. In 2011, the Indian population became the largest visible minority group and continues to be the fastest growing. Though the prevalence of chronic pain among Canadian Indians is unknown, research has found a higher prevalence among Indian women than men in India, Malaysia, Singapore, and the United Kingdom, with women reporting more severe pain. An understanding of how pain is experienced by this particular group is therefore important for providing culturally sensitive care.

    Aims: This study explores the lived experiences of chronic pain among immigrant Indian women in Canada.

    Methods: Thirteen immigrant Indian women participated in one-on-one interviews exploring daily experiences of chronic pain.

    Results: Using thematic analysis informed by van Manen's phenomenology of practice, four themes emerged: (1) the body in pain, (2) pain in the context of lived and felt space, (3) pain and relationships, and (4) pain and time. Women revealed that their experiences were shaped by gender roles and expectations enforced through culture. Specifically, a dual gender role was identified after immigration, in which women had to balance traditional household responsibilities of family labor and care alongside employment outside the home, exacerbating pain.

    Conclusions: This research uncovers the multifaceted nature of chronic pain and identifies factors within the sociocultural context that may place particular groups of women at greater risk of living with pain.

    BACKGROUND: Past research on work engagement has focused almost exclusively on either psychological or work-related factors in almost wholly separate literature. There is therefore a need to examine how these factors collectively influence work engagement.

    AIMS: To determine levels of work engagement and to identify psychological and work-related characteristics predicting work engagement in employees in Malaysia.

    METHODS: We recruited 5235 employees from 47 public and private organizations in Malaysia who responded to an online health survey. We assessed work engagement with the 9-item Utrecht Work Engagement Scale (UWES-9) and psychological distress using the 6-item Kessler scale. We performed multiple linear regression to determine predictors of work engagement.

    RESULTS: Employee mean age was 33.8 years (standard deviation [SD] ± 8.8). The mean work engagement score on the UWES-9 was 3.53 (SD ± 0.94). Eleven of 18 variables on multiple regression predicted work engagement, F(18, 4925) = 69.02, P < 0.001, R2 = 0.201. Factors that predicted higher work engagement were age, marital status, education level, job type, job permanency, longer sleep duration, lower psychological distress and no history of workplace bullying.

    CONCLUSIONS: Key factors associated with poorer work engagement in Malaysian employees include inadequate sleep, psychological distress and a history of workplace bullying. These are modifiable factors that individuals and employers can target to improve work engagement, ideally tailored according to occupational type.

    Background and aim: The effect of anticoagulation control on overall Health-Related Quality of Life (HRQoL) in patients taking warfarin in Malaysia has not been explored yet. Therefore, this study aimed to evaluate HRQoL among patients on warfarin in Malaysia.

    Methods: HRQoL among patients on warfarin was measured using WHOQOL-BREF (World Health Organization Quality of life Assessment: Brief Version). Descriptive and inferential statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 22.

    Results: Out of 319 patients, more female patients were observed than the males (n = 221, 69.3%, and n = 98, 30.7% respectively). Mean scores for the physical (61.14 ± 15.96), psychological (68.58 ± 16.11), social (63.55 ± 27.06) and environmental domains (62.78 ± 17.58) were observed.

    The datasets in this article provides supplementary information related to: (1) demographic profile of young offenders and (2) perpetrator experience in committing a crime. A quantitative approach based on a cross-sectional survey design was employed to collect data among 306 young offenders undergoing Community Service Order initiated by the Malaysian Social Welfare Department. The resultant data were analysed descriptively using Statistical Package for the Social Sciences (SPSS). The result stipulates that the majority of respondents are consist of male young offenders aged 20 years old, Malays, single in marital status, and unemployed. Based on the crime involvement aspect, the result indicates that young offenders involved in stealing (26.1%), does not carry any weapons while committing a crime (50.0%), and entangled in criminal activity due to peer influence (40.0%). Moreover, unfavorable luck contributes to the failure in executing crime (52.6%) which subsequently leads them to be arrested by the police (52.0%).

    BACKGROUND: Pneumococcal diseases were estimated to cause 1.6 million deaths annually worldwide in 2008, with approximately half of these occurring in children aged under 5 years. The consequences and deaths adversely impact individuals' and caregivers' work productivity.

    OBJECTIVES: This study aimed to quantify the potential lifetime productivity loss due to pneumococcal diseases among the pediatric population in Thailand using productivity-adjusted life years (PALYs).

    METHODS: A decision analytic model was used to estimate the burden of pneumococcal diseases among the current Thai population aged 0-5 years and followed up until aged 99 years or death. Base-case analysis compared years of life and PALYs lost to pneumococcal diseases. Scenario analyses investigated the benefits of prevention with pneumococcal conjugated vaccine 13 (PCV 13). All health outcomes were discounted at 3% per annum.

    RESULTS: The base-case analysis estimated that 453,401 years of life and 457,598 PALYs would be lost to pneumococcal diseases, equating to a loss of US$5586 (95% CI 3338-10,302) million. Vaccination with PCV13 at birth was estimated to save 82,609 years of life and 93,759 PALYs, which equated to US$1144 (95% CI 367-2591) million in economic benefits. The incidence of pneumonia in those aged 0-4 years, vaccine efficacy, and the assumed period of protection were key determinants of the health economic outputs.

    CONCLUSIONS: The disease and financial burden of pneumococcal diseases in Thailand is significant, but a large proportion of this is potentially preventable with vaccination.

    This article examined the factors of how long people would like to live involving 462 respondents aged 40 years and older in Malaysia. Data collected through an online self-administered survey indicated that 75% of the respondents would like to live at least 80 years and on average most people would like to live 81 years. Rural respondents, those who agreed that they have a loving family, those who agreed that they want to continue working for as long as they can, respondents who believed that they will not need long-term care at 65 years and older, and those who may consider living in an assisted living facility were more likely to want to live at least 80 years compared with respondents who did not agree. Efforts should be targeted at promoting healthy lifestyle and providing more employment opportunities for older persons.

    AIMS: This study identifies and analyses the risk factors contributing to nursing turnover in Saudi Arabia and identifies practical solutions to decrease turnover and encourage nurses to stay in their jobs.

    BACKGROUND: Saudi Arabia has a unique nursing profile, as the majority of the nursing workforce are expatriates. The Saudi health care system relies on contracted expatriate nurses to provide most of the direct patient health care. For nurses from other countries, Saudi Arabia can be a challenging place to work due to a range of factors including personal, policy and organisational variables. There is a high turnover of expatriate nurses, and this has been long-standing problem for the Saudi Arabian health care system.

    METHOD: A cross-sectional survey design among nurses in Saudi Arabia including 502 nurses, of whom 83.7% are female. Structural equation modelling is used to examine the relationships between the study variables. Confirmatory factor analysis is used to create and validate the measurement models for variables.

    RESULTS: The analysis of the survey data identifies that Filipino nurses are more likely to intend to leave their current position than other expatriates, including Malaysian, Pakistani, Indian or local Saudi nurses. Many expatriates identify discrimination as an important contributing factor for their intention to leave, citing that the national salary remuneration for nurses should be based on competency and delivery of care. Furthermore, several independent variables are found to be significant predictors of anticipated turnover, including discrimination; social support from immediate supervisor; organisational commitment; and autonomy.

    CONCLUSIONS: This study provides the most comprehensive information available to date about the factors that influence nurses' desire to leave their current job and provides evidence for better health workforce planning in Saudi Arabia. This study strongly indicates that the main factor related to turnover is the unfair and unequal salaries paid to nurses of different nationalities in Saudi Arabia.

    IMPLICATIONS FOR NURSING MANAGEMENT: The findings relating to both Saudi and foreign nurse employment could be helpful to policymakers and the Ministry of Health in Saudi Arabia.

    In this study, the solution casting method was employed to prepare plasticized polymer electrolytes of chitosan (CS):LiCO2CH3:Glycerol with electrochemical stability (1.8 V). The electrolyte studied in this current work could be established as new materials in the fabrication of EDLC with high specific capacitance and energy density. The system with high dielectric constant was also associated with high DC conductivity (5.19 × 10-4 S/cm). The increase of the amorphous phase upon the addition of glycerol was observed from XRD results. The main charge carrier in the polymer electrolyte was ion as tel (0.044) < tion (0.956). Cyclic voltammetry presented an almost rectangular plot with the absence of a Faradaic peak. Specific capacitance was found to be dependent on the scan rate used. The efficiency of the EDLC was observed to remain constant at 98.8% to 99.5% up to 700 cycles, portraying an excellent cyclability. High values of specific capacitance, energy density, and power density were achieved, such as 132.8 F/g, 18.4 Wh/kg, and 2591 W/kg, respectively. The low equivalent series resistance (ESR) indicated that the EDLC possessed good electrolyte/electrode contact. It was discovered that the power density of the EDLC was affected by ESR.

    This study employed Bacillus spp. with α-amylase production isolated from Malaysian hot spring for domestic kitchen food waste treatment contained grains, vegetables, chicken and tuna that mimic the food waste discharge from domestic kitchens in Malaysian household. Results showed that Bacillus licheniformis HULUB1 and Bacillus subtilis SUNGB2 possess excellent amylolytic properties. Highest α-amylase activity was obtained when both isolates were cultivated at pH 6.0 and 65 °C with concentrations of 18.15 U/mL for HULUB1 and 22.14 U/mL for SUNGB2. Stability of α-amylase with significant levels of enzyme activity were recorded at 55-85 °C and pH 5.0-9.0. The extracted mixed α-amylase of HULUB1 and SUNGB2 showed greatest reduction were achieved at day 12 with 45% ± 0.03 solid content at 65 °C. While the mixed culture of HULUB1 and SUNGB2 displayed an enhanced effect on the food waste contents reduction with 43% ± 0.02 solid content at 45 °C after day 12. The findings showed that the combination of the two Bacillus spp. isolates possessed degradation of food wastes at faster rate than α-amylase. It was also pointed out that the standard food waste (SFW) and the treatment process assimilated for this study was suitable for the growth of Bacillus spp.

    Basal stem rot (BSR) is a devastating disease to Malaysian oil palm. Current techniques employed for BSR disease detection on oil palm are laborious, time consuming, costly, and subjected to accuracy limitations. An ergosterol detection method was developed, whereby it correlated well with the degree of infection in oil palm. This current study was designed to study the relationship between Ganoderma biomass, ergosterol concentration, BSR disease progress and to validate the efficiency of microwave assisted extraction (MAE) method for extraction of ergosterol compound. In addition, testing on the sensitivity of thin layer chromatography (TLC) analysis for detection of ergosterol was also the aim of this study. The optimised procedure involved extracting a small amount of Ganoderma-infected oil palm root tissues suspended in low volumes of solvent followed by irradiation in a conventional microwave oven at 70°C and medium high power for 30 s, resulting in simultaneous extraction and saponification. Based on the results obtained, MAE method may be effective in extracting low to high yields of ergosterol from infected oil palm roots demonstrating disease scale 2, 3 and 4. Positive relationship was observed between ergosterol content and inoculation period starting day 3 in the inoculated oil palm seedlings and hour 6 in germinated seeds. TLC analysis demonstrated a good correlation with high performance liquid chromatography (HPLC) quantification. Therefore, a semi-quantitative TLC analysis may be applied for handling a large amount of samples during onset field survey.

    Insufficient attention has been given to the integration of the mediating effect of Internet gaming disorder (IGD) symptoms on loneliness and four components of aggression-physical aggression, verbal aggression, anger, and hostility-in the Malaysian context. In the present study, 410 participants with (a) at least 1 year of Internet gaming experience and (b) between ages 20- to 39 years were recruited using the probability proportional to size sampling method. Participants were undergraduate students and working adults. Self-reported questionnaires (the Internet Gaming Disorder Scale, University of California, Los Angeles Loneliness Scale, and the Buss-Perry Aggression Questionnaire) were used. The present study found that loneliness positively predicted four components of aggression (i.e., anger, hostility, physical aggression, and verbal aggression) and symptoms of IGD. Relationships between loneliness and the four components of aggression were partially mediated by IGD symptoms. The present study enriches and consolidates existing empirical evidence, particularly in the Malaysian context. If the mediating effect is not emphasized, it may lead to spurious conclusions that can significantly diminish the effectiveness of interventions that are meant to manage aggression.

    Background: The primary indicator of public health, which all nations aim to prolong, is life expectancy at birth. Uncovering its socioeconomic determinants is key to extending life expectancy. This study examined the determinants of life expectancy in Malaysia.

    Methods: This observational study employs secondary data from various official sources of 12 states and one federal territory in Malaysia (2002-2014). Panel data of 78 observations (13 cross-sections at six points in time) were used in multivariate, fixed-effect, regressions to estimate the effects of socioeconomic variables on life expectancy at birth for male, female and both-gender.

    Results: Poverty and income significantly determine female, male, and total life expectancies. Unemployment significantly determines female and total life expectancies, but not male. Income inequality and public spending on health (as a percentage of total health spending) do not significantly determine life expectancy. The coefficients of the multivariate regressions suggest that a 1% reduction in poverty, 1% reduction in unemployment, and around USD 23.20 increase in household monthly income prolong total life expectancy at birth by 17.9, 72.0, and 16.3 d, respectively. The magnitudes of the effects of the socioeconomic variables on life expectancy vary somewhat by gender.

    Conclusion: Life expectancy in Malaysia is higher than the world average and higher than that in some developing countries in the region. However, it is far lower than the advanced world. Reducing poverty and unemployment and increasing income are three effective channels to enhance longevity.

    BACKGROUND: The loss of productivity arising from tobacco use in low/middle-income countries has not been well described. We sought to examine the impact of cigarette smoking on population health and work productivity in Malaysia using a recently published measure, the productivity-adjusted life year (PALY).

    METHODS: A life table model was constructed using published Malaysian demographic and mortality data. Our analysis was limited to male smokers due to the low smoking prevalence in females (1.1%). Male smokers aged 15-64 years were followed up until 65 years or until death. The population attributable risk, health-related quality of life decrements and relative reduction in productivity due to smoking were sourced from published data. The analysis was repeated assuming the cohorts were never smokers, and the differences in outcomes represented the health and productivity burden conferred by smoking. The cost of productivity loss was estimated based on the gross domestic product per equivalent full-time worker in Malaysia.

    RESULTS: Tobacco use is highly prevalent among working-age males in Malaysia, with 4.2 million (37.5%) daily smokers among men aged between 15 and 64 years. Overall, our model estimated that smoking resulted in the loss of over 2.1 million life years (2.9%), 5.5 million (8.2%) quality-adjusted life years (QALYs) and 3.0 million (4.8%) PALYs. Smoking was estimated to incur RM275.3 billion (US$69.4 billion) in loss of productivity.

    CONCLUSION: Tobacco use imposes a significant public health and economic burden among working-age males in Malaysia. This study highlights the need of effective public health interventions to reduce tobacco use.

    Increasing demands for the supply of biopharmaceuticals have propelled the advancement of metabolic engineering and synthetic biology strategies for biomanufacturing of bioactive natural products. Using metabolically engineered microbes as the bioproduction hosts, a variety of natural products including terpenes, flavonoids, alkaloids, and cannabinoids have been synthesized through the construction and expression of known and newly found biosynthetic genes primarily from model and non-model plants. The employment of omics technology and machine learning (ML) platforms as high throughput analytical tools has been increasingly leveraged in promoting data-guided optimization of targeted biosynthetic pathways and enhancement of the microbial production capacity, thereby representing a critical debottlenecking approach in improving and streamlining natural products biomanufacturing. To this end, this mini review summarizes recent efforts that utilize omics platforms and ML tools in strain optimization and prototyping and discusses the beneficial uses of omics-enabled discovery of plant biosynthetic genes in the production of complex plant-based natural products by bioengineered microbes.

    Objective: Increasing amount of waste concurrently increases the risk of exposure to hazardous materials among waste collectors. Vigorous exertion in the field intensifies the abundance of contaminated inspirable droplets. If left undetected and untreated, it may provoke significant pernicious health effects and redundant burdens to employees and employers. The purpose of this study is to determine the prevalence of respiratory symptoms and their associated factors among domestic waste collectors.

    Results: A total of 290 waste collectors with a mean age of 40 (±9) years old were participated in the study. Most of them were from Kadazan-Dusun-Murut ethnic origin with educational background till secondary school. The average monthly income of the workers was USD 298.45 (±171.9) per month, and they had been in service for 11 (±9.04) years. Respiratory symptoms were seen in 21% of the workers. The identified significant risk factors were determined as underlying chronic diseases (OR=2.34; 95% CI=1.054, 5.219) and contact with pets (OR=1.87; 95% CI=1.004, 3.288).
