1.Repetitive strain injury (rsi) among computer users: a case study in telecommunication company
Malaysian Journal of Public Health Medicine 2016;16(Special Volume (1)):48-52
Repetitive Strain Injury (RSI) is the most common occupational injury faced by computer users. Computer users faced
higher possibility of getting RSI due to their prolonged working time and static posture. The three main objectives of
this study are, first: to identify the prevalence of RSI among computer users; second, to investigate and determine the
RSI risk factors; and third to analyze the association between RSI risk factors and the prevalence of RSI among computer
users at a Telecommunication Company X. A total of 100 respondents were selected based on their daily exposure to
computer usage of more than 4 hours. Nordic modified questionnaire was used to gather respondents’ sociodemographic
data, job’s information, physical risk exposure, physical symptoms and their awareness level towards RSI.
Body Parts Symptoms Survey (BPSS) form were also used to identify the body parts exposed to the RSI risk among
computer users. The data was analysed using Statistic Package for Social Science (SPSS) version 22. Study results showed
that the 41% of computer users in Telecommunication Company X felt tired at the upper-back near the neck and 38%
at the shoulder region. In conclusion, the prevalence of RSI among computer users is high at upper back near the neck
and at the shoulder region. There is a significant association between risk factors of RSI and the prevalence of RSI
among the computer users at Telecommunication Company X.
2.Inter and intra termites colonies comparisons of gut microbial diversity from worker and soldier caste of Globitermes sulphureus (Blattodea: Termitidae) using 16S rRNA gene
Malaysian Journal of Microbiology 2017;13(3):228-234
Aims: The present study aims at isolation and identifying termite gut bacteria from different Globitermes sulphureus
mounds using a molecular approach based on16S rRNA genes.
Methodology and results: The bacteria from the whole gut of soldier and worker castes of the termite G. sulphureus
was isolated and identified. The diversity of the bacteria was compared between five different colonies in Universiti Sains
Malaysia, Penang, Malaysia. The isolated bacteria were identified by using 16S rRNA gene sequencing method and
subsequently used for phylogenetic analysis. Sequences analyses of identified bacteria were found to be affiliated with
the phyla Firmicutes, Proteobacteria, and Actinobacteria. Soldiers and workers seemed to have little differences in
bacterial species from the same colonies. We noted some bacteria which were detected in soldiers were not detected in
workers.
Conclusion, significance and impact of study: Differences in the culturable bacteria composition were not significant
between termite colonies. However, the phylogenetic analysis revealed that most of the bacteria from one colony were
slightly but distinctly different with bacteria from other colonies.
3.Knowledge, Attitude and Practice towards Smoking among International Islamic University Malaysia Kuantan Communities
The International Medical Journal Malaysia 2016;15(2):19-26
Smoking is an issue that has spread around the world throughout the years. The majority of smokers have
the intention to quit smoking, but due to some factors, it may prevent their intention. Research and
interventions have been done in many countries to decrease the smoking prevalence. This cross-sectional
study aimed to find out the associations of knowledge, attitude and practice (KAP) towards smoking and
to identify the factors associated with knowledge and attitude towards smoking, in priority to
sociodemographic factors among the International Islamic University Malaysia Kuantan (IIUMK) communities,
including between students and workers. One hundred fifteen respondents of students and workers from
IIUMK were investigated with a self-administered questionnaire starting from 10-01-2014 to 10-02-2014. The
data were analysed using SPSS software. Respondents had good knowledge and practice, and moderate
attitude towards smoking. There was weak positive correlation between knowledge with attitude (r=+0.193,
p=0.038) and practice (r=+0.206, p=0.028), also moderate correlation between attitude and practice
towards smoking (r=+0.626, p<0.001). There was no factor found to be associated with knowledge, but
significant association was found between attitude towards smoking with gender (p<0.001), education level
(p=0.016) and smoking status (p<0.001). Although, the mean values of KAP levels were higher for workers,
but it was not statistically significant as compared to the students. These study findings suggested that the
main obligation are more for students to improve their KAP level towards smoking as they are fresh
generation who will educate and lead the upcoming generation of Malaysia.

5.Comparison Of The Anaerocult A And The Oil Blocking Methods For The In Vitro Cultivation Of Entamoeba Histolytica
The Malaysian Journal of Pathology 2015;37(3):271-274
Entamoeba histolytica, the causative agent for human amoebiasis, is among the most deadly
parasites, accounting for the second highest mortality rate among parasitic diseases. Because this
parasite dwells in low oxygen tension, for its cultivation, microaerophilic conditions are required to
mimick the human gut environment. Several methods developed for optimal growth environment are
commercially available and some are conventionally modified in-house which include the Anaerocult
A and oil blocking preparation methods. This study was undertaken to compare the reliability of the
Anaerocult A and the oil blocking methods in generating anaerobic environment for cultivation of
E. histolytica. The trophozoites of E. histolytica HM1: IMSS strains were axenically cultivated in
TYI-S-33 medium in culture incubated anaerobically by using Anaerocult A (Merck) and mineral
oil blocking method. The outcomes of both methods were determined by the minimum inhibitory
concentration (MIC) of metronidazole against E. histolytica by giving a score to the growth pattern
of the trophozoites. The reliability of both methods was assessed based on susceptibility testing of
E. histolytica to metronidazole. The MIC obtained by both anaerobic condition methods was 6.25ug/
ml, thus showing that oil-blocking method is comparable to the Anaerocult A method and therefore,
considered as a reliable method for generating an anaerobic environment for the cultivation of E.
histolytica.
6.In vitro Antibacterial Properties of Etlingera elatior Flower Extracts against Acne-Inducing Bacteria: Propionibacterium acnes and Staphylococcus aureus
The International Medical Journal Malaysia 2019;18(3):128-135
Introduction: Acne is a common skin disorder and is generally caused by Propionibacterium acnes and
Staphylococcus aureus. Etlingera elatior flower extract is known to have antibacterial properties however,
the properties against these bacteria have not been extensively reported. Thus, this study aimed to
investigate the antibacterial properties of the flower extract against these bacteria. Materials and
Methods: The flower extract was subjected to sequential extraction using three different solvent
polarities; n-Hexane, dichloromethane (DCM) and ethanol. The antibacterial properties were evaluated
using the disc diffusion and broth dilution assays techniques by determining the inhibition zone diameter,
minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Total phenolic
acids (TPC) and flavonoids contents (TFC) were estimated using Folin-Ciocalteu and aluminium-chloride
colorimetric assay respectively. Morphological changes of the treated bacteria were studied using scanning
electron microscope (SEM). Results: DCM flower extract showed the highest antibacterial properties against
P. acnes; at 25 mg/ml it had the widest inhibition zone (11.39 ± 0.45 mm) and the lowest MIC (6.25 mg/
mL) and MBC (12.5 mg/mL). The ethanolic flower extract had the highest antibacterial properties against
S. aureus; at 50 mg/ml the inhibition zone was 6.21 ± 0.25 mm and the MIC and MBC were both 12.5 mg/
mL. Ethanolic extracts had the highest TPC (966.304 ± 114.08 mg GAE/g) and TFC (796.33 ± 65.78 mg QE/
g). There was significant morphological changes of the treated bacteria observed under SEM. Conclusion: E.
elatior flower extracts exhibited antibacterial properties against acne-inducing bacteria.
7.Development of Sentence Speech Materials for Speech-In-Noise Training in Adults
Malaysian Journal of Health Sciences 2018;16(Special Issue (Abstract)):215-
This paper describes the systematic process followed in the development of culturally appropriate equalized speech-in-noise sentences suitable for use in an adaptive Speech-In-Noise training protocol for adults in Malaysia. The process involved three iterative phases of development. They were (1) analysis, (2) design and (3) development phases. In the analysis phase, important variables that needed to be considered for speech-in-noise materials were identified through literature review and discussion with the experts in the field. Next, in the design phase, the compilation and formation of sentences, evaluation of naturalness and recording of the speech materials were done. The last phase was the development phase which involved the evaluation of performance intensity function and equalization of intelligibility. The final outcome of these phases were 171 sentences with equal intelligibility that can be used interchangeably in a speech-in-noise training protocol for adults in Malaysia

Objective: This study aims to establish the validity and reliability of the Malaytranslated version of the CES-D. Methods: This study employed a cross-sectional
study design. The participants were female inmates (n=90) from local prisons which were selected based on purposive-selective sampling. The analyses include face validation, factor analysis, and reliability testing. A test-retest was
conducted within a one-week interval. Results: The mean score for depression among the participants is 18.97 (SD=6.51). Further descriptive analysis showed
that 58.9% of them scored above the mean score, which is considered high. Preliminary construct validation analysis confirmed that factor analysis was appropriate for the Malay-translated version of the CES-D. Furthermore, the
factor analysis showed similar factor loadings to the original English version. The total internal consistency of the translated version, which was measured by
Cronbach’s alpha coefficient, was equal to 0.75. The test-retest reliability of the total score, measured by Pearson’s correlation was equal to 0.69. Conclusions:
Face validity, construct validity, and reliability analysis were found satisfactory for the Malay-translated version of the CES-D. The Malay-translated version of
the CES-D was found valid and reliable to be used in future studies, with comparable properties to the original version and to previous studies.

Job satisfaction is defined as pleasurable or positive emotional state which results from the appraisal of one’s job or job experience. It is often determined by how well outcome meet or exceed expectations. There are many factors which are related to job satisfaction among family physicians. Data on satisfaction among family physicians varies from country to country. This study aimed to determine the level of job satisfaction among family physicians in Malaysia and its associated factors. A cross sectional study was performed among 117 Family physicians in Malaysia between July 2012 and December 2012. A questionnaire consists of socio-demographic characteristic, professional and health clinic characteristics and Warr-Cook-Wall job satisfaction scale was used. The results showed that 85% of Malaysian family physicians are satisfied with their job. They are mostly satisfied with hours of work, colleagues and fellow workers, and freedom to choose own method of working. They are least satisfied with physical working condition, rate of pay and recognition. Female gender and less number of health clinics in-charged were associated with increased in overall job satisfaction. Most of the family physicians in Malaysia are satisfied with their job. However there are certain areas that should be looked into which are physical working condition, rate of pay and recognition. Malaysian family physicians should receive equal career opportunity, promotion and salary scale like other specialties.

Asian Pacific Journal of Tropical Biomedicine 2015;(11):841-844
This review focuses on studies concerning cryptosporidiosis in three Asian countries. Cryptosporidium spp. infection was investigated in children<12 years old afflicted with diarrhoea and admitted to the paediatric hospitals in Iraq, Jordan and Malaysia. Most of the patients complained of abdominal pain, watery diarrhoea and mild-to-severe dehydration. Stool samples were collected from children and five methods were used to detect oocysts of Cryptosporidium spp. including:direct wet mount, Sheather’s sugar flotation, formalin-ether sedimentation, modified Ziehl-Neelsen and direct fluorescent antibody (DFA). The infection rate was 8.56, 37.3 and 4.6 in Iraq, Jordan and Malaysia respectively. A combination of formalin ether sedimentation and acid fast stain was used to detect Cryptosporidium oocysts in Iraq. The DFA test showed the highest sensitivity for samples of children in Jordan. In Malaysia, direct wet mount, formalin-ether sedimentation, modified Ziehl-Neelsen and DFA gave the same results (4.62%) while Sheather’s sugar flotation was 3.85%. Source of drinking water appeared to be an important risk factor in transmission of infection. In Jordan, the high rate of infection was recorded in rainy season (January–May).
