Yulita Y, Idris MA, Dollard MF

Int J Occup Saf Ergon, 2020 Oct 15.
PMID: 32912109 DOI: 10.1080/10803548.2020.1822054

Objective. Our innovation was to propose a multilevel model to explain how an organizational factor, psychosocial safety climate (PSC) - the climate for worker psychological health - related to work investment (work engagement and workaholism) and, in turn, psychological distress. Methods. Longitudinal data were collected in Peninsular Malaysia across 26 police departments from 392 police personnel, matched across 4 months, and were tested using hierarchical linear modeling. Results. The analysis revealed between-group effects linking PSC to job resources, to work engagement and to workaholism. When PSC operated by improving job resources, aside from increased work engagement, it could unwittingly boost workaholism. However, this only existed under low PSC conditions. The secondary function of PSC buffered the impact of job resources on workaholism and psychological distress. When PSC was high, job resources reduced both workaholism and psychological distress, suggesting that PSC enabled resources to do their job of mitigating unfavorable conditions. Conclusions. Results support a multilevel PSC-extended job demands-resources motivational path with cross-links, and PSC's moderation function, as an explanation of worker psychological health. Confirming PSC as a leading indicator and the importance of a motivational path, this article presents new evidence in support of targeting PSC to improve worker psychological health.

MyJurnal

The objective of this study is to identify the relationship between task characteristics (variety of skills, task identity, task significance, autonomy, feedback) and employee engagement. The study was conducted in a healthcare service in Sabah, Malaysia. A self administered questionnaire was used to collect data by using convenience sampling. A total of 78 respondents participated in the study. Data was analyzed using Spearman Correlation. The results revealed a significant and positive relationship between task characteristics (variety of skills, task identity, task significance, autonomy, feedback) and employee engagement in the studied organization. This has important implications to employers. It is recommended that managers, human resource development (HRD) practitioners and supervisors provide employees with more challenging tasks, autonomy and feedback from time to time. Moreover, work designs should include how the tasks may improve employee identity and significance.

Fulltext Penetrating ocular trauma by nail of a badminton feather shuttle cock: A rare case report

Das S, Singh V, Saurabh K

Indian J Ophthalmol, 2020 06;68(6):1209-1211.
PMID: 32461485 DOI: 10.4103/ijo.IJO_1681_19

Sports-related ocular traumas may be rare, but can have devastating and disabling consequences. The causes of eye-related injuries depend on the type of sports popular in a particular area or country. Badminton is a popular sport played by all age groups and socioeconomic segments and is popular in many parts of the world. It is most popular in South-East Asia, accounting for two-thirds of all ocular sports injury in Malaysia. In India, badminton has become quite popular in recent years. Shuttlecocks in badminton have been shown to be responsible for a high number of outpatient ocular sports-related, mostly blunt injuries. We report an unusual case of penetrating ocular injury due to a feather shuttlecock and its surgical management.

Yap PSX, Ahmad Kamar A, Chong CW, Yap IKS, Teh CSJ

J Glob Antimicrob Resist, 2020 06;21:246-251.
PMID: 32304769 DOI: 10.1016/j.jgar.2020.03.024

BACKGROUND: Resistance to colistin, the last line therapy for infections caused by multidrug-resistant Gram-negative bacteria, represents a major public health threat. Citrobacter freundii B9-C2 which was isolated from the stool of preterm neonate on the first week of life, displayed resistance to almost all major antibiotics, including colistin. Through whole genome sequencing (WGS), we characterised the genome features that underline the antibiotic-resistance phenotype of this isolate.
METHODS: Genome of C. freundii B9-C2 was sequenced on an Illumina MiSeq platform. The assembled genome was annotated and deposited into GenBank under the accession number CP027849.
RESULTS: Multiple antimicrobial resistance genes including blaCMY-66 were identified. Further, the presence of 15 antibiotic efflux pump-encoding resistance genes, including crp, baeR, hns, patA, emrB, msbA, acrA, acrB, emrR, mdtC, mdtB, mdtG, kdpE, mdfA and msrB, were detected and likely to account for the observed cephalosporins, carbapenems, aminoglycosides and monobactams resistance in C. freundii B9-C2. The isolate also presented unique virulence genes related to biofilm formation, motility and iron uptake. The genome was compared to publicly available genomes and it was closely related to strains with environmental origins.
CONCLUSION: To the best of our knowledge, this is the first report of intestinal carriage of colistin-resistant C. freundii from the stool of a neonate in Malaysia. Using genomic analysis, we have contributed to the understanding of the potential mechanism of resistance and the phylogenetic relationship of the isolates with draft genomes available in the public domain.

Application of artificial intelligence methods for monsoonal river classification in Selangor river basin, Malaysia

Wong YJ, Shimizu Y, Kamiya A, Maneechot L, Bharambe KP, Fong CS, et al.

Environ Monit Assess, 2021 Jun 22;193(7):438.
PMID: 34159431 DOI: 10.1007/s10661-021-09202-y

Rivers in Malaysia are classified based on water quality index (WQI) that comprises of six parameters, namely, ammoniacal nitrogen (AN), biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved oxygen (DO), pH, and suspended solids (SS). Due to its tropical climate, the impact of seasonal monsoons on river quality is significant, with the increased occurrence of extreme precipitation events; however, there has been little discussion on the application of artificial intelligence models for monsoonal river classification. In light of these, this study had applied artificial neural network (ANN) and support vector machine (SVM) models for monsoonal (dry and wet seasons) river classification using three of the water quality parameters to minimise the cost of river monitoring and associated errors in WQI computation. A structured trial-and-error approach was applied on input parameter selection and hyperparameter optimisation for both models. Accuracy, sensitivity, and precision were selected as the performance criteria. For dry season, BOD-DO-pH was selected as the optimum input combination by both ANN and SVM models, with testing accuracy of 88.7% and 82.1%, respectively. As for wet season, the optimum input combinations of ANN and SVM models were BOD-pH-SS and BOD-DO-pH with testing accuracy of 89.5% and 88.0%, respectively. As a result, both optimised ANN and SVM models have proven their prediction capacities for river classification, which may be deployed as effective and reliable tools in tropical regions. Notably, better learning and higher capacity of the ANN model for dataset characteristics extraction generated better predictability and generalisability than SVM model under imbalanced dataset.

Fulltext Mixed POT-BM Approach for Modeling Unhealthy Air Pollution Events

Masseran N, Safari MAM

Int J Environ Res Public Health, 2021 06 23;18(13).
PMID: 34201763 DOI: 10.3390/ijerph18136754

This article proposes a novel data selection technique called the mixed peak-over-threshold-block-maxima (POT-BM) approach for modeling unhealthy air pollution events. The POT technique is employed to obtain a group of blocks containing data points satisfying extreme-event criteria that are greater than a particular threshold u. The selected groups are defined as POT blocks. In parallel with that, a declustering technique is used to overcome the problem of dependency behaviors that occurs among adjacent POT blocks. Finally, the BM concept is integrated to determine the maximum data points for each POT block. Results show that the extreme data points determined by the mixed POT-BM approach satisfy the independent properties of extreme events, with satisfactory fitted model precision results. Overall, this study concludes that the mixed POT-BM approach provides a balanced tradeoff between bias and variance in the statistical modeling of extreme-value events. A case study was conducted by modeling an extreme event based on unhealthy air pollution events with a threshold u > 100 in Klang, Malaysia.

Fulltext Plant species- and stage-specific differences in microbial decay of mangrove leaf litter: the older the better?

Pradisty NA, Amir AA, Zimmer M

Oecologia, 2021 Apr;195(4):843-858.
PMID: 33559746 DOI: 10.1007/s00442-021-04865-3

Leaf litter and its breakdown products represent an important input of organic matter and nutrients to mangrove sediments and adjacent coastal ecosystems. It is commonly assumed that old-grown stands with mature trees contribute more to the permanent sediment organic matter pool than younger stands. However, neither are interspecific differences in leaf decay rates taken into account in this assumption nor is our understanding of the underlying mechanisms or drivers of differences in leaf chemistry sufficient. This study examines the influence of different plant species and ontogenetic stage on the microbial decay of mangrove leaf litter. A litterbag experiment was conducted in the Matang Mangrove Forest Reserve, Malaysia, to monitor leaf litter mass loss, and changes in leaf litter chemistry and microbial enzyme activity. Four mangrove species of different morphologies were selected, namely the trees Rhizophora apiculata and Bruguiera parviflora, the fern Acrostichum aureum and the shrub Acanthus ilicifolius. Decay rates of mangrove leaf litter decreased from A. ilicifolius to R. apiculata to B. parviflora to A. aureum. Leaf litter mass, total phenolic content, protein precipitation capacity and phenol oxidase activity were found to decline rapidly during the early stage of decay. Leaf litter from immature plants differed from that of mature plants in total phenolic content, phenolic signature, protein precipitating capacity and protease activity. For R. apiculata, but not of the other species, leaf litter from immature plants decayed faster than the litter of mature plants. The findings of this study advance our understanding of the organic matter dynamics in mangrove stands of different compositions and ages and will, thus, prove useful in mangrove forest management.

Mohd Sani N, Aziz Z, Kamarulzaman A

Ther Innov Regul Sci, 2021 05;55(3):490-502.
PMID: 33231863 DOI: 10.1007/s43441-020-00243-y

INTRODUCTION: Biosimilars are a cost-effective alternative to original biologic medicines that allow patients access to biologic therapies for various chronic diseases. Our paper aims to provide an overview of biosimilars in Malaysia with emphasis on the comparison of Malaysian guidelines with guidelines from well-established regulatory agencies, a review of biosimilars' market approval and their reported adverse effects (AEs) as well as clinical trials conducted in Malaysia.
METHODS: We searched the official websites of the National Pharmaceutical Regulatory Agency (NPRA) Malaysia and three other well-established agencies, online databases of Medline® and EMBASE for guidelines on legislation and regulations of biosimilars. Meanwhile, we extracted the reports of AEs involving biosimilars in Malaysia from the NPRA database and for global AEs from the World Health Organisation VigyLize database. The ClinicalTrials.gov Website by the U.S. National Library of Medicines was the source for data on clinical trials.
RESULTS: Malaysia followed the principles of the European Medicines Agency biosimilar regulations and issued their guideline in 2008. Since then, NPRA has approved 24 biosimilar products and recorded 499 AE reports, of which 43 (8.6%) were serious. NPRA has also approved ten Phase III clinical trials in Malaysia with four trials still ongoing.
CONCLUSION: Malaysia follows a stringent regulatory pathway for the approval of biosimilars enacted by well-established regulatory agencies to maintain the quality, efficacy and safety of biosimilars. Introducing biosimilars to the Malaysian market would improve patients' accessibility to biologic therapies.

The determinant factors for macroinvertebrate assemblages in river ecosystems are varied and are unique and specific to the type of macroinvertebrate family. This study aims to assess the determinant factors for macroinvertebrate assemblages in a recreational river. The study was conducted on the Ulu Bendul River, Negeri Sembilan, Malaysia. A total of ten sampling stations were selected. The research methodology included (1) water quality measurement, (2) habitat characterization, and (3) macroinvertebrate identification and distribution analysis. The statistical analysis used in this study was canonical correspondence analysis (CCA) to represent the relationship between the environmental factors and macroinvertebrate assemblages in the recreational river. This study found that most of the families of macroinvertebrates were very dependent on the temperature, DO, NH3-N, type of riverbed, etc. All of these factors are important for the survival of the particular type of macroinvertebrate, plus they are also important for selecting egg-laying areas and providing suitable conditions for the larvae to grow. This study advises that improved landscape design for watershed management be implemented in order to enhance water quality and physical habitats, and hence the protection and recovery of the macroinvertebrate biodiversity.

PMID: 22691763 MyJurnal

Meal and snack patterns are associated with energy and nutrient intakes and consequently health and nutritional status. The aim of this paper is to describe the percentage of daily energy intake from meals and afternoon snack among Malaysian adults. The study included a representative sample of adults aged 18-59 years (n=7349) from a nationwide Food Consumption Survey conducted by the Ministry of Health. Information on dietary intake was obtained using a one day 24-hour diet recall (24-HDR). Dietary data on 6886 adults were analysed using Nutritionist ProTM and statistical analysis was carried out using the SPSS 13.0. The median percentage of daily energy intake is reported only for adults consuming meals and afternoon tea and by socio-demographic characteristics as well as body mass index (BMI) status. More than 80% of Malaysian adults consumed morning meals, lunch and dinner and 54% reported having afternoon tea. The median percentage of energy intake from morning meals, lunch, dinner and afternoon tea was 29.9%, 30.5%, 32.4% and 17%, respectively. There were variations in the median percentage of energy from meals and snacks according to the socio-demographic variables and BMI status. It is important to understand the eating patterns of Malaysians as the information can assist in efforts to address obesity and diet-related chronic diseases among adults.

PMID: 22691762 MyJurnal

This study reports the food consumption patterns of adults aged 18 to 59 years in the Malaysian Adults Nutrition Survey (MANS) carried out between October 2002 and December 2003. A total of 6,742 subjects comprising 3,274 men and 3,468 women representing the northern, central , southern and east coast of Peninsular Malaysia as well as Sabah and Sarawak were interviewed. A semiquantitative food frequency questionnaire (FFQ) which consisted of 126 food items was used to evaluate the food consumption pattern (habitual food intake) of the respondents during the previous one- year period. The results demonstrate that nasi putih (cooked rice) was consumed by 97% of the population twice daily (average 2½ plates per day). Other food items consumed daily were marine fish, (one medium fish per day), green leafy vegetables (one cup per day) and sweetened condensed milk (three teaspoons per day. The mean frequencies for daily intake of rice, leafy vegetables, marine fish, local kuih, anchovy (ikan bilis) and biscuits were significantly higher among the rural compared to the urban adults. In contrast, more urban dwellers consumed chicken and eggs more frequently than their rural counterparts. More men than women consumed chicken and eggs more frequently. Malaysian adults showed a satisfactory habit of drinking plain water, with 99% drinking at least six glasses of plain water daily. Other beverages such as tea (47%), coffee (28%), chocolate-based drinks (23%) and cordial syrup (11%) were also consumed on daily basis, however, in a smaller proportion of the population. There were differences in the prevalence of daily consumption of foods when comparing urban and rural population, and also between men and women. The prevalence of daily consumption of marine fish among rural and urban adults was 51% and 34% respectively. For sweetened condensed milk, men and women consumed 43% and 28% respectively; however, more women drank full cream milk than men. Between the age groups, 21% of adults below 20 years old consumed chicken at least once a day, while this pattern of intake was not shown in the older age groups. Our findings show that adults, aged 50 to 59 years old, had the highest prevalence of daily consumption of full cream milk with 24% while those aged 18 to 19 years old had the lowest prevalence of daily consumption at 15%. The food consumption pattern of Malaysian adults appears to be satisfactory. However, some changes in food habits are recommended especially in substituting the less wholesome sweetened condensed milk with the more nutritious full cream or skimmed milk.

Nutrition surveys based on a representative sample of the Malaysian adult population have hitherto not been reported. In 2003, the Ministry of Health, Malaysia, conducted the Malaysian Adult Nutrition Survey (MANS), the first and largest nutrition survey in the country which aimed to provide detailed quantitative information on nutritional status, food and nutrient intakes, and physical activity pattern on a nationwide representative sample of adult subjects between the ages of 18 and 59 years. The survey covered four zones in Peninsular Malaysia (Central, Southern, Northern and East Coast), Sabah and Sarawak. This paper presents the mean and selected percentiles of energy and nutrient intake of 6886 subjects by selected demographic and socioeconomic characteristics. Energy contributions by macronutrients and dietary adequacy in relation to the Recommended Nutrient Intake for Malaysians are also described. Information on dietary intake was collected by trained nutritionists using a one day 24-hour diet recall. Dietary data were analysed using Nutritionist Pro, a diet analysis software and statistical analysis was carried out using the SPSS ver. 13.0. In most of the demographic and socioeconomic groups, males had higher mean energy (1776 kcal) and nutrient intake and percent achievement of RNI than females (1447 kcal). The proportions of calories derived from macronutrients were within the recommendations for a healthy diet. Intake of micronutrients such as iron, calcium and vitamin A was about 50% of RNI particularly in women. Sodium intake of Malaysians, not reported in earlier studies, is also made available. Under-reporting using the EI/BMR ratio was found in half of the population studied. The present study provides the first national estimates of energy and nutrient intake of the Malaysian adult population. Regular nutrition surveys are needed at the national level to provide valuable information on trends in food and nutrient intake, particularly among age and ethnically diverse subgroups of the population.

Dilution rate of compost leachate from different biowaste for the fertigation of vegetables

Ahamad Sanadi NFB, Ibrahim N, Ong PY, Klemeš JJ, Li C, Lee CT

J Environ Manage, 2021 Oct 01;295:113010.
PMID: 34348429 DOI: 10.1016/j.jenvman.2021.113010

Compost leachate (CL) is often treated as sewage. Limited studies have characterised the use of CL for agriculture application due to the variation of nutrient range, potential pollutants and need for pretreatment before use. This paper reviewed the characteristics of CL in terms of its nutrients and physical characteristics from three types of biowastes, i.e. the organic portion of municipal solid waste (OP-MSW), animal manure and green waste. The nutrient range characterised are used to develop the dilution rate of the CL as fertigation water for three types of vegetables. The dilution rate of CL developed is based on the fertigation standards set by the Food and Agriculture Organization of the United Nations and Malaysia Standards. The results show that all CL contain high organic content and micronutrients, which exceeded the upper limits. For the fertigation of vegetables using the CL, based on the requirement of COD and micronutrients (Fe, Mn, Zn, Cu, Pb, Ni, Cd, Cr) of the vegetables, the CL from green waste required the lowest dilution rate (8-45 fold), followed by animal waste (33-65 fold) and the OP-MSW (193-1770 fold). The novel dilution range developed is vital to balance the essential nutrients in the CL while avoiding phototoxicity on plant and soil pollution. The dilution strategy developed is essential to support the conversion of CL as an organic liquid fertiliser for agricultural application.

PMID: 25210584 MyJurnal

THE DIVERSITIES OF MANGROVE TREES AND OF THEIR ASSOCIATED GASTROPODS WERE ASSESSED FOR TWO MANGROVE REGIONS ON THE WEST COAST OF PENINSULAR MALAYSIA: Langkawi Island and Sungai Merbok. The mangrove area sampled on Langkawi Island was recently logged and replanted, whereas the area sampled in Sungai Merbok was part of a protected nature reserve. Mangrove and gastropod diversity were assessed in four 50 m(2) (10 × 5 m) sites per region. The species richness (S), Shannon Index (H') and Evenness Index (J') were calculated for each site, and the mean S, H' and J' values were calculated for each region. We report low tree and gastropod S, H' and J' values in all sites from both regions. For Langkawi Island, the mean S, H' and J' values for mangrove trees were S = 2.00±0, H' = 0.44±0.17 and J' = 0.44±0.17; the mean S, H' and J' values for gastropods were S = 4.00±1.63, H' = 0.96±0.41 and J' = 0.49±0.06. In Sungai Merbok, the mean S, H' and J' values for mangrove trees were S = 1.33±0.58, H' = 0.22±0.39 and J' = 0.22 ±0.39; the mean S, H' and J' values for gastropods were S = 4.75±2.22, H' = 1.23±0.63 and J' = 0.55±0.12. This study emphasises the need for baseline biodiversity measures to be established in mangrove ecosystems to track the impacts of anthropogenic disturbances and to inform management and restoration efforts.

PMID: 26868710 MyJurnal

A study of the reproductive cycle of the hard clam, Meretrix lyrata, was documented based on histological observation and Gonad Index (GI). Samples were taken from estuarine waters of the Buntal River in Sarawak, Malaysia. The gonad of M. lyrata started to develop in September 2013. Gametogenesis continued to develop until the maturation and spawning stage from February to April 2014. The GI pattern for a one-year cycle showed a significant correlation with chlorophyll a. The corresponding GI with chlorophyll a suggested that the development of the reproductive cycle of M. lyrata required a high amount of food to increase gametogenesis.
