Stress reduces the performance and productivity of employees.
One of the most important stressors originate from organizational factors,
which are decision latitude, psychological demand, social support and job
insecurity. This creates four kinds of jobs: passive, active, low strain and high
strain. The objective of the study is to determine the association between
organizational factors with occupational stress and cortisol level among
lecturers in University Selangor. This cross-sectional study used a purposive
sampling, which involved 45 lecturers from various faculties. The instrument
used in this study was Job Content Questionnaire (JCQ) which is a
Psychosocial Job Assessment Instrument designed by Karasek et al., (1998).
The questionnaire has been translated to Malay version by Edimansyah et al.,
(2006). 10ml of blood sample was collected from each respondent by certified
phlebotomist. Results from the statistical analysis showed that majority of the
respondents were female (75.6%), aged below forty years old (82.2%), married
(77.8%) and hold a master degree (68.9%). Most of the respondents were
found having low decision latitude 35(77.5%). Majority of the respondents
were also found in passive group 13(28.9%) which were having low
psychological job demand and low decision latitude, while others are in low
strain 11(24.4%), high strain 11(24.4%) and active group 10(22.2%)
respectively. There was a significant association between two organizational
factors with occupational stress level, which are decision latitude and
psychological job demand (p0.05). As a
conclusion, two out of four organizational factors, which are decision latitude
and psychological job demand showed a significant association with
occupational stress levels. Cortisol as one of stress biomarkers may not be
significant due to small sample size.
Construction industry is one of the major contributors towards Malaysian economy and socio-economy. It is an important
industry gearing Malaysia towards developed nation status. However, fatalities in this industry are a crucial problem. Number of
fatalities in this industry is the highest compare to other industries registered in Malaysia. The contributing factors can be separated
into immediate (human and worksite elements) and underlying (management and external). Occupational safety and health (OSH)
management is a challenge in the construction industry due to its hazardous nature. A framework of construction OSH management
consisting of policy, process, personnel and incentive elements were tested. 13 respondents from 13 residential projects comprising of
high-rise and low-rise in Pulau Pinang were interviewed. It was found that the immediate factors are being more recognized by the
respondents compare to the underlying factors. Human element is perceived as the most significant contributor, while the external
element is the least significant. In terms of construction OSH management, process and personnel elements are the most significant in
developing an effective OSH management programme.
A cross sectional study was conducted among tea plantation workers in Cameron Highlands from July to December 2006 to study the prevalence of low back pain and factors associated with it. One hundred and six tea plantation field workers participated in the study. Data was collected using self-administered questionnaire. Time motion studies were also conducted for 3 different job categories. The prevalence of back pain experienced throughout their work in the plantation was 81.1% and the prevalence of low
back pain experienced in the past 12 months was 64.2%. Feeling the need to work as fast as possible was a significant predictor of low back pain and increased the risk by 3.5 times, therefore it is suggested that both the management and workers give serious attention to this particular aspect to reduce the incidence of low back pain.
The occurrences of occupational accidents and incidents are increasing in parallel with the growth of industries
such as mining and quarrying. The main objective of this study was to analyze data on the perception of occupational
accidents in the mining and quarrying sector in Malaysia. The data was collected and examined based on the
questionnaires on the level of perception of accident investigation in mining and quarrying sector. Statistical data
reported by the Department of Occupational Safety and Health (DOSH) was also reviewed. The findings of this study
prove that the level of perception of workers towards occupational accident issues in mining and quarrying sector
is still in the moderate level with the mean value of 3.28. The findings show that 51.7% of the workers agree while
25.9% totally agree to the accident occurrence. Only 1.7% of the workers are not aware of accident occurrence at the
workplace. Employers and employees must carry out their responsibilities to prevent accidents by adhering to health
and safety practices at the workplace.
Recent statistics from the Social Security Organization (SOCSO) of Malaysia shows Commuting Accident (CA)
increased consistently by 1500 cases per year from 2008 to 2012. This has resulted in the rising of fatality rate,
extensive claims of compensation payment and not to mention loss of valuable talents. However, little is known
about the contributing factors to the occurrences of CA in Malaysia because CA is never considered to be work
related before. This study aims to explore work related factors with occurrence of CA using 5-year statistical data
from SOCSO, Malaysia. Moreover, we also reviewed studies published between 1990s and 2014 to support the
statistical findings. Motorbike is found as the most common vehicle used which involved in CA. Individual factors
concerning workers behaviour is a main risk factor of CA. Family related factors (parenting responsibility), work
burden, workplace support as well as environmental factors such as bad weather and bad road conditions are also
significant contributions of CA. It is very important to develop behavioural intervention strategies and provide proper
training. Hence, more attention should be directed to young individual workers in balancing them with capabilities and
organization performance demand. This may lead to the elimination of the other causes of CA. In conclusion, solutions
to this problem involve not only a particular party to ensure the wellbeing of workers in Malaysia, but all authorities
should play roles in enhancing safety and health matter of workers especially on the occurrence of accident.
Occupational safety and health (OSH) in Small and Medium Enterprises (SMEs) have not received the proper
attention not only in Malaysia, but in most of the countries globally, in terms of research or support for implementation.
This research focuses on the implementation of the occupational safety and health in small and medium industries in
the southern region of peninsular of Malaysia. The objective of this research is to determine the level of awareness of
SME owners and also their employers towards the importance of implementing OSH in their daily tasks. This study
will be based on conducting a survey to 200 SMEs owners and workers throughout the southern region of Malaysia.
The results from this research can be use as a benchmark for other researchers to further enhance the research in this
area.
The use of remote sensing in detecting aerosol or air pollution is not widely applied in Malaysia. The large area of coverage provided by remote sensing satellite may well be the solution to the lack of spatial coverage by the local ground air quality monitoring stations. This article discusses the application of remote sensing instruments in air quality monitoring of Malaysia. The remote sensing data is validated using ground truths either from local ground air monitoring stations or the Aerosol Robotic Network (AERONET). The correlation between remote sensing is relatively good with R from 0.5 to 0.9 depending on the satellite used. The correlation is much improved using the mixed effects algorithm applied on MODIS Aerosol Optical Depth (AOD) data. Accuracy of predicted air quality data by remote sensing is generally tested using the Root Mean Squared Error (RMSE) against the ground truths data. Besides the Geographic Information System (GIS) tools are used in manipulating the data from both remote sensing and ground stations so as to produce meaningful results such as spatio-temporal pattern mapping of air pollution. Overall the results showed that the application of remote sensing instruments in air quality monitoring in Malaysia is very useful and can be improved further.
Ficus deltoidea or locally known as Mas cotek is one of the common medicinal plants used in
Malaysia. Our previous studies showed that this plant have blood glucose lowering effect. Glucose
uptake into muscle and adipocytes cells is one of the known mechanisms of blood glucose lowering
effect. This study was performed to evaluate the effect of Ficus deltoidea on glucose uptake activity
into muscle cells. The cells were incubated with Ficus deltoidea extracts either a,lone or combination
with insulin. Amount of glucose uptake by L6 myotubes was determined using glucose tracer, 2-deoxy-
[l-:-Hj-glucose. The results showed that Ficus deltoidea extracts at particular doses enhanced basal or
insulin-mediated glucose uptake into muscle cells significantly. Hot aqueous extract enhanced glucose
uptake at the low concentration (10 pg/ml) whereas methanolic extract enhanced basal glucose uptake
at high concentrations (500 and 1000 fig/ml). Meanwhile, ethanolic extract enhanced glucose uptake at
low and high concentrations. Methanolic extract also mimicked insulin activity during enhancing
glucose uptake into L6 muscle cells. Glucose uptake activity of Ficus deltoidea could be attributed by
the phenolic compounds presence in the plant. This study had shown that Ficus deltoidea has the
ability to enhance glucose uptake into muscle cells which is partly contributed the antidiabetic activity
of this plant.
Degradation or decline of soil quality that cause shallow slope failure may occur due to physical or chemical processes. It can be triggered off by natural phenomena, or induced by human activity through misuse of land resources, excessive development and urbanization leading to deforestation and erosion of covered soil masses causing serious threat to slopes. The extent of damage of the slopes can be minimized if a long-term early warning system is predicted in the landslide prone areas. The aim of the study was to characterize chemical properties of stable and unstable slope along selected highways of Malaysia which can be manipulated as indicator to forecast shallow slope failure. The elements in soil chemical properties contributed to each other as binding agents that affected the existing soil structure. It could make the soil structure strong or weak. Indicators that can be used to predict shallow slope failure were low content in iron, lead, aluminum, chromium, zinc, low content of organic carbon and CEC.
The objectives of this study were to determine level of acquisition, implementation and differences of pedagogical content knowledge among physical education teachers It also examined the relationship between pedagogical content knowledge and its implementation during physical education lesson. About 149 of Form 4 physical education teachers in Ulu Kinta, Perak, Malaysia secondary schools and 125 physical education teachers of X class in upper secondary schools of Surabaya, Indonesia were involved in this study. Data of the study was collected through questionnaires The findings delineate a medium level (M = 2.90) of pedagogical content knowledge of Malaysian physical education teachers and 86.3% have implemented in their lessons. Whilst the Indonesian physical education teachers acquired a high level of pedagogical content knowledge (M = 3.69) and 94.2% have implemented during their physical education lessons. There was a significant (p = .00) difference among Malaysian and Indonesian physical education teachers on acquisition of pedagogical content knowledge. The findings also delineate a medium positive and significant relationship between pedagogical content knowledge and its implementation during physical education lesson of Malaysian (r = .622, p < .01) and Indonesian (r = .647, p < .01) physical education teachers respectively. The results of the study implied that pedagogical content knowledge is a specific domain to teaching process. Teachers are able to develop their current dimension and goals or contemporary of pedagogical content knowledge based on current needs and their own ability and contentment. Therefore, teachers should acquire pedagogical content knowledge so that their teaching would be meaningful and effective for students learning.
Miscarriage is one of the most common complications in pregnancy. There is emerging evidence that psychological impact following miscarriage is not unusual. Understanding the magnitude of psychological morbidity is important in the management of miscarriage. The main objective of this study was to compare the mean Hospital Anxiety and Depression Scale (HADS) score between women with miscarriage and women with successful pregnancy and to determine the sociodemographic factor and clinical characteristic that are associated with anxiety and depression. A descriptive case control study was conducted in a teaching hospital, over a period of 12-months (from October 2014 till September 2015). A total of 65 women were recruited with 32 women as the study group (miscarriage) and another 33 women as the control group (women with successful pregnancy). Mean HADS-anxiety score was higher in the study group compared to control group although it was not statistically significant (6.53 ± 3.427 vs 5.73 ± 2.875, p=0.309). Mean HADS-depression score was higher in the control group (4.34 ± 2.695 vs 4.45 ± 3.073, p=0.878). Women with maternal age more than 35 years and history of previous miscarriage had a higher tendency of anxiety and depression with higher mean HADS score. There was no association between other sociodemographic data and clinical characteristic with risk of anxiety and depression. As conclusion, there was no significant difference in women with miscarriage as compared to those with successful pregnancies, although older women with history of miscarriage had a preponderance to both disorders.

Adult influenza and pneumococcal vaccinations are grossly underutilized although there is clear benefit in reducing mortality and morbidity among those at risk. The aim of the study was to assess primary care physician’s knowledge on adult influenza and pneumococcal vaccinations, their beliefs and barriers to vaccination. A cross-sectional study using self-administered questionnaires was conducted at eight primary care centres in Kuching, Sarawak. A total of 108 primary care physicians participated in this study. Median age of participants was 29 years (IQR 4.0). The median knowledge score for influenza vaccine was 9 (IQR 3) and for pneumococcal vaccine was 8 (IQR 4). Female participants scored higher compared to their male counterparts for influenza and pneumococcal vaccines (P = 0.005 & 0.007). The highest percentage of correct responses for influenza vaccination was for side effects (75.3%) while the lowest was for contraindications (9.3%). The highest percentage of correct responses for pneumococcal vaccination was for side effects (69.1%) while the lowest was for advocated target groups (6.2%). Most participants believed that pneumococcal and influenza vaccines were safe (92.8 & 99%) and beneficial for patients (89.7 & 93.8%). Cost of influenza and pneumococcal vaccines (94.8% & 96.9%) and their availability (86.6% & 89.7%) were the main barriers to prescribing them. Primary care physicians in the public sector have moderate knowledge of both adult vaccinations. Areas of knowledge paucity and barriers need to be addressed to ensure a more comprehensive health care delivery to the aging Malaysian population.

Acanthamoeba spp. merupakan ameba hidup bebas yang biasa ditemui
di persekitaran. Ia merupakan agen penyebab keratitis Acanthamoeba (AK)
dan ensefalitis ameba bergranuloma (GAE). Ameba ini juga mampu menjadi
perumah kepada pelbagai bakteria termasuklah yang bersifat patogenik seperti
Mycobacterium, Legionella dan Staphylococcus aureus rintang metisilin (MRSA).
Berdasarkan maklumat ini, satu kajian dijalankan untuk mengesan kehadiran tiga
bakteria endosimbion berkepentingan perubatan di dalam Acanthamoeba spp. yang
telah dipencilkan dari bolong penghawa dingin yang terdapat di wad and dewan
bedah di Pusat Perubatan Universiti Kebangsaan Malaysia. Kehadiran bakteria
endosimbion ini disaring menggunakan pasangan primer khusus bagi setiap genus
menggunakan reaksi rantai polimerase (PCR) konvensional dan disahkan dengan
analisis penjujukan. Dua puluh sembilan (80.56%) pencilan Acanthamoeba spp.
didapati mengandungi bakteria endosimbion patogenik yang disasarkan dengan
sekurang-kurangnya satu genus bakteria bagi setiap pencilan. Mycobacterium
(82.76 %) adalah bakteria yang paling banyak dikesan, diikuti dengan Legionella sp.
(65.52 %) dan Pseudomonas spp. (62.07 %). Tiada bakteria MRSA dikesan daripada
mana-mana pencilan dalam kajian ini. Dua endosimbion Mycobacterium yang
dikenalpasti telah dikelompokkan ke dalam strain Mycobacterium tuberculosis.
Kami membuat kesimpulan bahawa, kebanyakan Acanthamoeba berpotensi untuk
menjadi perumah bagi pelbagai bakteria patogenik, namun implikasi interaksi ini
terhadap patogenisiti kedua-dua organisma masih kurang jelas dan memerlukan
penyelidikan yang lebih lanjut.
Septic arthritis of the hip in children represents a serious disorder with unfavourable long-term sequelae. In neonates, a poor hip outcome is expected especially if the treatment was delayed. Late sequelae can lead to structural joint damage and instability, causing deformity and dislocations which ultimately may result in limb length discrepancy, early degenerative changes and limited range of motion. Surgery at the appropriate time can improve the hip condition and functional outcome. Previous classifications of post septic hip sequelae are useful guides for treatment, but did not discuss one particular group of patient. This group-septic hip dislocation with a preserved femoral head, has recently been described as a distinct entity. This report highlights an 11-year follow-up of a 2-year-old child who had a successful outcome following open reduction and varus derotation
osteotomy for a septic hip dislocation with a preserved femoral head.

Air pollution can be detected through rainwater composition. In this study, long-term measurements (2000-2014) of wet deposition were made to evaluate the physicochemical interaction and the potential sources of pollution due to changes of land use. The rainwater samples were obtained from an urban site in Kuala Lumpur and a highland-rural site in the middle of Peninsular Malaysia. The compositions of rainwater were obtained from the Malaysian Meteorological Department. The results showed that the urban site experienced more acidity in rainwater (avg=277mm, range of 13.8 to 841mm; pH=4.37) than the rural background site (avg=245mm, range of 2.90 to 598mm; pH=4.97) due to higher anthropogenic input of acid precursors. The enrichment factor (EF) analysis showed that at both sites, SO42-, Ca2+ and K+ were less sensitive to seawater but were greatly influenced by soil dust. NH4+ and Ca2+ can neutralise a larger fraction of the available acid ions in the rainwater at the urban and rural background sites. However, acidifying potential was dominant at urban site compared to rural site. Source-receptor relationship via positive matrix factorisation (PMF 5.0) revealed four similar major sources at both sites with a large variation of the contribution proportions. For urban, the major sources influence on the rainwater chemistry were in the order of secondary nitrates and sulfates>ammonium-rich/agricultural farming>soil components>marine sea salt and biomass burning, while at the background site the order was secondary nitrates and sulfates>marine sea salt and biomass burning=soil components>ammonia-rich/agricultural farming. The long-term trend showed that anthropogenic activities and land use changes have greatly altered the rainwater compositions in the urban environment while the seasonality strongly affected the contribution of sources in the background environment.
Altered mental status in the setting of polytrauma poses a challenge to the emergency team managing the patient. The tendency to miss positive findings in these circumstances increases several folds due to multiple factors such as depressed mental status/intoxication, presence of distracting injuries and concurrent life-threatening injuries that require more urgent attention. In view of this, NEXUS (National Emergency X-Radiography Utilization Study) criteria of clearing the cervical spine was adopted and used worldwide. Consensus on clearance of the other parts of spine is still lacking. This case reports highlights the findings in a 18-yrs-old male who presented with altered mental status, facial pain and abrasion, following a motor vehicle accident. Facial bone fracture was diagnosed and he was discharged. Three days later, he came with severe epigastric pain. Tenderness on palpation was noted at the spine and Computed Tomography (CT) scan was done. Multiple thoracic vertebra fractures were seen. As a conclusion, thorough primary and secondary survey should be done in patients who have regained full consciousness prior to discharge in order to avoid overlooking other serious injuries.

Multiple myeloma is a blood dyscrasias that accounts of almost 10% of all hematological malignancy. The presentation of myeloma kidney is highly variable and it often presents as renal insufficiency, renal tubular dysfunction and proteinuria of various types. In Malaysia the true incidence of myeloma kidney is unknown. Often the diagnosis of myeloma kidney was missed out despite the patient has sought medical treatment early. A high index of suspicion is required when the middle to elderly age patients present with unexplained renal impairment and enlarged kidneys. We present here the presentation of a rare subtype of myeloma in a relatively young patient whereby the patient presented with nephrotic syndrome and aoztemia.
This article highlights the case of a 44-year old Malay man who is diagnosed as having treatment resistant schizophrenia on Clozapine, which then developed Polycythemia Rubra Vera (PRV). It is known that a major side effect for Clozapine is of agranulocytosis, that is a potentially fatal side effect. However, there have been reported disturbances of other hematological parameters, which result in other abnormalities including leucopenia, leucocytosis, thrombocytopenia, thrombocytosis and eosinophilia. Could this case be a pure medical condition of PRV or is there a relation to the effects of Clozapine? In this paper, the aim is to report a case of blood dyscrasia in a 44-year old male who developed Polycythemia Rubra Vera a year after he was observed to have abnormal full blood count results.
This study is to determine the prevalence and the associated factors of low-back pain (LBP), which has multifactorial causes, among ambulance workers in Kelantan, Malaysia. The cross-sectional study involved ambulance workers in the emergency department in all government hospitals in Kelantan. Those who did not consent, complete or return the questionnaire as well as having rheumatic diseases were excluded from the study. The participants were asked to answer a self-administered questionnaire in English. Descriptive analyses and Chi-square test were used. A total of 168 respondents had completed the questionnaires with a response rate of 85.0%. Questionnaires with more than 95.0% items completed were included in the analysis (n=143). The respondents had a higher proportion of male than female (63.6% versus 36.4%). Assistant Medical Officer comprised of 60.0% of all respondents and the rest were nurses. The respondents’ age ranged between 23 to 58 years old with a mean age of 38.27 and standard deviation (SD) of 7.27. The mean duration of involvement in ambulance service was 9.68 years (SD 6.97). The majority (98.5%) of the respondents were Malay. Gender, smoking status and hobbies were the associated factors of LBP among ambulance workers. The modifiable risk factors should be emphasized to the ambulance workers as a measure to prevent the development of LBP.
This quantitative-oriented research was conducted to identify factors that contributed to errors in dispensing medication among nurses and to understand why nurses did not report their errors in dispensing. In this study a total of 284 U29 nurses participated in focusing on factors contributing to medication errors and failure to report the errors. In this study, analysis of the data collected was made in two sections; dispensing errors and failure to report the errors in giving medication. According to Evans et al. (2006) although nurses may not admit directly to such errors, they expressed their perceptions towards situations described in the questionnaire items as contributing to medication errors among nurses. Almost all in the sample of 284 chose not to report medication errors because they could not identify the cause of dispensing errors; other nurses perceived that the individual involved is not competent in performing the task. Other reasons include fear that the action will be exposed by the management, to avoid publicity from the media, and there is no difference in reporting or not reporting the medication errors. This study was done not only for exploring factors of medication errors; it also aspires to identify problems that arise in hospital services and in order to maintain the quality of health care. The management should consider the impact of medication errors and failure to report medication errors on the nursing profession and quality image of the hospital.
