    This study explores the role of sterols as lipid bio markers to assess organic matter variations and their sources in surface sediments of Kuala Selangor, Selangor which involved extraction procedures and sterol compounds analyzed using GC-MS. Ten sterol compounds were found in the samples with phytosterols being the principal compounds which accounted 79 % of total sterols. This was followed by cholesterol and fecal sterols, each constitutes 6 % of total sterols while the rest are in the ranged of 1-5 %. Sterol Source Index (SSI) also reflected phytosterols predominant at all sampling stations but in different degree based on phytosterols compounds. Another issue was sewage contamination assessment using coprostanol/ cholesterol, coprostanol/ (coprostanol + cholestanol) and epi coprostanol/ coprostanol ratio. No sewage contamination occurred in the study area even though fecal sterols have been quantified. This analytical study indicates that the sediments in the study area consisted of a mixture of sterols from various sources even though dominated by phytosterols originated from terrestrial plants.

    Dengue fever is a recurring public health problem afflicting thousands of Malaysians annually. In this paper, the risk map for dengue fever in the peninsular Malaysian states of Selangor and Kuala Lumpur was modelled based on co-kriging and geographical information systems. Using population density and rainfall as the model's only input factors, the area with the highest risk for dengue infection was given as Gombak and Petaling, two districts located on opposite sides of Kuala Lumpur city that was also included in the risk assessment. Comparison of the modelled risk map with the dengue case dataset of 2010, obtained from the Ministry of Health of Malaysia, confirmed that the highest number of cases had been found in an area centred on Kuala Lumpur as predicted our risk profiling.

    A terrestrial gamma radiation survey for the state of Selangor, Kuala Lumpur and Putrajaya was conducted to obtain baseline data for environmental radiological health practices. Based on soil type, geological background and information from airborne survey maps, 95 survey points statistically representing the study area were determined. The measured doses varied according to geological background and soil types. They ranged from 17 nGy h −1 to 500 nGy h −1 . The mean terrestrial gamma dose rate in air above the ground was 182 ± 81 nGy h −1 . This is two times higher than the average dose rate of terrestrial gamma radiation in Malaysia which is 92 nGy h −1 (UNSCEAR 2000). An isodose map was produced to represent exposure rate from natural sources of terrestrial gamma radiation. - Highlights: • A methodology is presented to reduce terrestrial gamma dose rate field survey. • Geological background of acid intrusive of granitic type has the highest dose rates. • The mean dose rate is 2 times higher than the world average. • Isodose map of terrestrial gamma radiation for Selangor, Kuala Lumpur and Putrajaya was produced

    The aim of this study is to provide information on the concentration of metals in cockles (Anadara granosa) from Kuala Selangor, Malaysia. Cockles in this study area were taken by local people as part of their diet, therefore necessary to determine metal concentrations in the cockles. Sample collection activity was conducted at Kuala Selangor (03degree20' N - 101degree15 ' E) between the month of March, and April 2012. About two kilograms of samples were purchased from local fish market at Kuala Selangor. The concentration of Cd, Cr, Cu, Pb, Fe and Zn in the samples were analysed using Inductively Coupled Plasma Optical Emission (ICP-OES). The observed mean concentration of Cd, Cr, Cu, Pb, Fe and Zn is 1.48±0.33, 1.43±0.91, 15.78±5.28, 1.11±0.46, 875.55±343.43 and 94.17±7.91 mg/ kg respectively. From the public health point of view, these metal concentrations were below the maximum permissible levels set by the Malaysian Food Act (1983) and Regulations (1985). Therefore, cockles from Kuala Selangor are safe for human consumption. (author)

    Cerebral Palsy (CP) describes a group of chronic conditions affecting body movement and muscle coordination caused by damage to one or more areas of the brain, occurring at any time during foetal development to infancy. This research was carried out to learn how parents of children with cerebral palsy (CP) had found and accessed services provided for them in Selangor and Kuala Lumpur. It was based in the Spastic Children's Association of Selangor and Federal Territory (SCAS&FT) among 96 of 201 parents of children who use the facilities and services provided by the SCAS&FT through questionnaires and face-to-face interviews. There was a satisfactory level of availability and accessibility of contacting and using the services provided by SCAS&FT in terms of respondent satisfaction. However, parents had varying levels of awareness of the different classes and activities carried out by the school. Efforts to improve knowledge regarding the services available for children with CP in the general population and among parents of these children should be promoted.

    Vegetable is an essential daily diet item for the people of Malaysia. This work addressed the radiation and heavy metal exposure scenarios through the consumption of vegetables. Kuala Selangor is located in Sungai Selangor estuary in the west coast of Peninsular Malaysia, which is susceptible to pollution load due to the presence of large-scale industrial and human activities. Radioactivity and heavy metals level in human diet is of particular concern for the assessment of possible radiological and chemical hazards to human health. Therefore, a comprehensive study was carried out to determine the radioactivity levels ((226)Ra, (228)Ra and (40)K) and heavy metal concentrations (Cr, As, Cd, Mn, Mg, Al, Sr, Rb, Sb, Ba, Hg, Fe, Ni, Zn, Cu, Bi and Pb) in 10 varieties of vegetable collected from different farmlands in Kuala Selangor region. The committed doses for (226)Ra, (228)Ra and (40)K due to consumption of vegetables were found 16.6±1.3, 23.6±1.7 and 58±5 µSv y(-1), respectively, with a total of 98±8 µSv y(-1). This dose imposes no significant threat to human health. The estimated cancer risk shows that probability of increase in cancer risk from daily intake of vegetables is only a minor fraction of International Commission on Radiological Protection values. The concentrations of heavy metal were below the daily intake recommended by the international organisations. © The Author 2015. Published by Oxford University Press. All rights reserved.

    Full Text Available Background: Agriculture is an important sector for the Malaysian economy. The use of pesticides in agriculture is crucial due to its function in keeping the crops from harmful insects. Children living near agricultural fields are at risk of pesticide poisoning. Objective: To evaluate the genotoxic risk among children who exposed to pesticides and measure DNA damage due to pesticides exposure. Methods: In a cross-sectional study 180 Orang Asli Mah Meri children aged between 7 and 12 years were studied. They were all living in an agricultural island in Kuala Langat, Selangor, Malaysia. The data for this study were collected via modified validated questionnaire and food frequency questionnaire, which consisted of 131 food items. 6 urinary organophosphate metabolites were used as biomarkers for pesticides exposure. For genotoxic risk or genetic damage assessment, the level of DNA damage from exfoliated buccal mucosa cells was measured using the comet assay electrophoresis method. Results: Out of 180 respondents, 84 (46.7% showed positive traces of organophosphate metabolites in their urine. Children with detectable urinary pesticide had a longer tail length (median 43.5; IQR 30.9 to 68.1 μm than those with undetectable urinary pesticides (median 24.7; IQR 9.5 to 48.1 μm. There was a significant association between the extent of DNA damage and the children's age, length of residence in the area, pesticides detection, and frequency of apple consumption. Conclusion: The organophosphate genotoxicity among children is associated with the amount of exposure (detectability of urinary pesticide and length of residence in (exposure the study area.

    2001-01-01

    Observations of salinity, temperature, suspended sediment concentration (SSC) and tidal current velocity were made in the lower and along the longitudinal axis of Sungai Selangor estuary over neap-spring cycles. The variations of these parameters at the measurement stations and along the channel are presented to illustrate the water and sediment dynamics in the estuary. The results shows that the Sungai Selangor estuary changes from a partially-mixed type during neaps to a well-mixed one during springs, promoted by stronger tidal energy during the higher tidal ranges. The strong neap density stratification is also promoted by the high river discharges during the measurement period. Maximum concentration of suspended sediment (> 2000 mg/l) occurs during maximum current velocities both during flood and ebb. The maximum salinity was achieved during high water slack but the salt water was totally flushed out of estuary during low water springs. The longitudinal axis measurement indicates that a partially-developed zone of turbidity maximum with a sediment concentration over 1000 mg/l was observed at the limit of salt water intrusion in salinity range less than 1 ppt. Tidal pumping as oppose to the estuarine circulation is the more dominant factor in the maximum formation as the salt water is totally excluded at low water. (Author)

    There are few data on paediatric melioidosis in endemic areas outside rural north-eastern Thailand and northern Australia. This study reports 16 culture-confirmed cases of melioidosis in children aged Kuala Lumpur, Malaysia. Seven (43.8%) patients had septicaemic melioidosis (with three known deaths) and nine (56.2%) had localised disease (one death). Eleven (68.8%) patients had underlying diseases, including five with haematological malignancies. Skin, soft tissue and lymph nodes were most commonly affected. There were no cases of parotitis or pharyngocervical disease (seen in Thailand), or encephalomyelitis (seen in Australia). The differences in disease seen in this study compared with the mostly rural patients described in previous studies might be owing to a different patient population in an urban environment. Septicaemic melioidosis has a high mortality, but localised disease has a good prognosis, and selected cases may be cured without the full recommended treatment regimen.

    There have been few detailed studies on thyroid cancer (TC) in Malaysia, a multiethnic country with three major races - Malays, Chinese and Indians. The paper retrospectively audits the records of 107 consecutive cases with histologically proven thyroid cancer between 1995 and 2000 presenting to University Hospital, Kuala Lumpur. The demographic distribution, histological variants, mode of presentation, sensitivity of fine needle aspiration cytology and the modalities of treatment are examined in the present paper. Of a total of 107 cases of TC, 74 were papillary, 23 follicular, one Hurthle Cell, seven medullary and two anaplastic. There were 91 women and 16 men; the corresponding median age of presentation being 34.0 and 40.0 years. The median age at presentation of TC was 36 years in the Malay population, 37 in the Chinese population and 33 in the Indian population. Fifty-six per cent of follicular cancer incidence was in the Malay population alone, the remaining in the other populations. Solitary thyroid nodule was seen in 75 patients, generalized enlargement in 20 and no goiter in 11. Local symptoms were reported in population. Total thyroidectomy in WDTC, although controversial, remains the mainstay of surgical treatment in Malaysia.

    We review our experience with 27 cases of pulmonary and meningeal cryptococcosis at the University Hospital, (Kuala Lumpar, Malaysia) where this is the most common cause of adult meningitis in patients without debilitating illnesses. Of the 27 cases analysed, six presented primarily with pulmonary symptomatology which usually were mainly cough, chest pain and low grade fever. The rest presented with primarily central nervous system (CNS) symptomatology of which headaches and fever were the most consistent symptoms although a third of these patients also had pulmonary lesions noted on chest radiographs. Treatment in all cases was with amphotericin B and 5-fluorocytosine and usually till a total cumulative dose of 1.5 g of amphotericin had been reached (an average of 10 weeks). Primary pulmonary presentations, if symptomatic, were treated as per CNS cryptococcosis due to the high likelihood of CNS dissemination. Incidental pulmonary cryptococcoma found on routine chest radiographs were confirmed by biopsy under ultrasound or fluoroscopy guidance and booked for surgical resection. Death usually occurred early in patients who presented late. Once patients responded to therapy, mortality was usually avoided. The only cause of morbidity in survivors was visual impairment or blindness, and this was attributed mainly to intracranial hypertension with residual deficits determined by the measures taken to lower intracranial pressures. Our experience suggests that: (i) symptomatic patients should have combination therapy with 5-fluorocytosine and amphotericin B till at least a cumulative dose of 1.5 g amphotericin B is reached irrespective of whether they have primary CNS or pulmonary symptomatology; (ii) non-symptomatic pulmonary cryptococcoma could be treated primarily by surgical resection; (iii) visual failure or papilloedema should be treated aggressively; and (iv) prognosis is good with adequate therapy and early presentation.

    Full Text Available Studies have shown that low adoption rate among citizens has been hindering the optimization of e-Government services especially in developing countries. Hence, one of the critical measures that has to be undertaken is to identify and overcome possible barriers to further facilitate a higher rate of adoption. A multistage stratified sampling was used in this study to collect data from 1000 respondents, both user and non-user residing in the state of Selangor, Malaysia. This state was chosen as to provide a better understanding of low adoption when issues of basic facilities have been successfully overcome. An exploratory factor analysis was performed to identify latent constructs and seven key factors were identified. A multiple regression model was subsequently used to analyze significant factors in determining the willingness to use e-Government services. The determinants are language barrier, educational level, secure, format, easy to use, enjoyable, reliable, visual appeal and infrastructure. The result shows significant variables that act as barriers to adoption are reliable, enjoyable, easy to use, secure, and language used. The constraints pointed out in the open ended questions mainly focus on the issue of accessibility, ease of use and awareness. Overcoming these obstacles is therefore crucial in order to enhance the usage of e-Government services which consequently will improve the quality of public administration in Malaysia.

As consequences, pregnant mother, lactating mother and children do not eat the taboo foods so that it can reduce their food intake and finally it can decrease their nutritional status. The objectives of this study are 1 to identify taboo foods, 2 to identify reasons of taboo food and 3 to improve basic nutrition knowledge through training on food and nutrition.  Study was conducted in Barito Kuala South Kalimantan from December 2005 to November 2006. A sample of size 36 households was drawn randomly from household population of size 180. The households population is household farmer who are beneficiary of Special Program for Food Security, Food and Agriculture Organization. Data were analyzed quantitatively and qualitatively and presented in one way table. Results show that groups which had many food taboo were pregnant woman group and lactating mother group. There are 7 taboo foods for pregnant woman and 11 taboo foods for lactating mother. Some taboo foods for pregnant women are ice, twin banana, young coconut, coconut water, young pineapple and fish. Some taboo foods for lactating mother are egg, fresh fish, fish, sugar, salt, jackfruit, fat food, hot food, etc. After attending training, the knowledge on nutrition and food of the farmers increase significantly, therefore it is hoped  that their knowledge can reduce their believe of the food taboo.  Keywords: taboo food, food intake, nutrition knowledge.

    A cross sectional descriptive study of 2048 subjects was conducted to determine the prevalence of depression and factors influencing depression among students in secondary school from urban and rural areas in the state of Selangor, Malaysia. The children's depression inventory (CDI) developed by Maria Kovacs was used in this study. Students who participated in this study come from two urban schools and three rural schools. It was found that in the yield for scores for five factors were 9.2% have negative mood, 5% have interpersonal problems, 8.3% have ineffectiveness, 9.8% have anhedonia and 10.6% have negative self esteem. Following the interpretive guidelines for the T-scores, it was found that 10.3% of the students were much above average in the depression scale. This study also found that: 1% of students were smoking, 1.6% of students were gum sniffling, 0.9% took drugs, 4.1% took alcohol and 9.9% took things from other people. Females were more depressed than males. The Chinese students were more depressed compared to Indian students. Students whose parents had no formal education or had only primary education were more depressed than students whose parents had secondary, college or university education. Depression increased with increasing number of siblings. Depression contributed to the habit of drug abuse, gum sniffing and stealing but not to smoking and alcohol abuse. Suicidal tendencies were more likely among the depressed students. It is imperative that not only caregivers but also teachers have to be equipped with the knowledge, attitude and skills to assist secondary school children cope with their emotions, handle conflicts and manage stress early so that a more productive society will develop in the future.

    Fourteen beta-agonists were quantitatively analyzed in cattle, chicken and swine liver specimens purchased at 14 wet markets in Selangor State, Malaysia, by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The health risks of ractopamine and clenbuterol residues in the Malaysian population were assessed based on quantitative data and meat consumption statistics in Malaysia. Wastewater samples collected at swine farms (n = 2) and cattle/cow farms (n = 2) in the Kuala Langat district were analyzed for the presence for the 14 compounds. Wastewater in chicken farms was not collected because there was negligible discharge during the breeding period. The environmental impacts caused by beta-agonists discharged from livestock farms were spatially assessed in the Langat River basin using a geographic information system (GIS). As a result, 10 compounds were detected in the liver specimens. Ractopamine, which is a permitted compound for swine in Malaysia, was frequently detected in swine livers; also, 9 other compounds that are prohibited compounds could be illegally abused among livestock farms. The health risks of ractopamine and clenbuterol were assessed to be minimal as their hazard quotients were no more than 7.82 × 10 -4 and 2.71 × 10 -3 , respectively. Five beta-agonists were detected in the wastewater samples, and ractopamine in the swine farm resulted in the highest contamination (30.1 μg/L). The environmental impacts of the beta-agonists in the Langat River basin were generally concluded to be minimal, but the ractopamine contamination released from swine farms was localized in coastal areas near the estuary of the Langat River basin because most swine farms were located in that region.

    Anxiety is the most common mental health disorders in the general population. This study aimed to determine the prevalence of anxiety, its associated factors and the predictors of anxiety among adults in the community of Selangor, Malaysia. A cross sectional study was carried out in three districts in Selangor, Malaysia. The inclusion criteria of this study were Malaysian citizens, adults aged 18 years and above, and living in the selected living quarters based on the list provided by the Department of Statistics Malaysia (DOS). Participants completed a set of questionnaires, including the validated Malay version of Generalized Anxiety Disorder 7 (GAD 7) to detect anxiety. Of the 2512 participants who were approached, 1556 of them participated in the study (61.90%). Based on the cut-off point of 8 and above in the GAD-7, the prevalence of anxiety was 8.2%. Based on the initial multiple logistic regression analysis, the predictors of anxiety were depression, serious problems at work, domestic violence and high perceived stress. When reanalyzed again after removing depression, low self-esteem and high perceived stress, six predictors that were identified are cancer, serious problems at work, domestic violence, unhappy relationship with family, non-organizational religious activity and intrinsic religiosity. This study reports the prevalence of anxiety among adults in the community of Selangor, Malaysia and also the magnitude of the associations between various factors and anxiety.

    Full Text Available This study is to see the level of acculturation of Javanese and Malay Islams in Javanese community wedding at Selangor Malaysia. According to the theory of culture, each culture has a uniqueness, as a individual uniqueness. The unique culture of Javanese ethnic wedding in Selangor is believed to be a process of negotiation between Malay and Javanese culture.. Acculturation theory is used in this research to explain and understand the reality of that culture. The study concluded that ethnic wedding traditions of Javanese Islam in Selangor pointed to the high level of acculturation. The acculturation leads to a “substitution” and “syncretism”. The substitution refers to the meaning that the Javanese tradition for the most replaced with new cultures (Malay. Acculturation can also be said as a cultural syncretism, the mixing of these two cultures into a new culture that are distinctive.Copyright (c 2016 by KARSA.

    There are established differences in cardiovascular disease in different racial groups. Worldwide, the literature regarding the clinical epidemiology of congestive heart failure (CHF) in non-white populations is scarce. To document the prevalence of CHF in the multiracial population of Malaysia, and to describe the clinical features and management of these patients. Busy city centre general hospital in Kuala Lumpur, Malaysia. Of 1435 acute medical admissions to Kuala Lumpur General Hospital over the 4-week study period, 97 patients (6.7%) were admitted with the primary diagnosis of CHF. Coronary artery disease was the main aetiology of CHF, accounting for almost half (49.5%) the patients, followed by hypertension (18.6%). However, there were variations in associated aetiological factors between ethnic groups, with diabetes mellitus affecting the majority of Indians-as well as underutilisation of standard drugs for CHF, such as the angiotensin converting enzyme (ACE) inhibitors, which were only used in 43.3%. Amongst acute medical admissions to a single centre in Malaysia the prevalence of CHF was 6.7%. Coronary artery disease was the major aetiological factor in heart failure accounting for almost half the admissions. The under-prescription of ACE inhibitors was similar to other clinical surveys carried out amongst Caucasian populations in the West.

    Nowadays, coastal zones are facing shoreline changes that stemming from natural and anthropogenic effect. The process of erosion and accretion will affect the physical environment of the shoreline. Therefore, the study of shoreline changes is important to identify the patterns of changes over time. The rapid growth of technology nowadays has facilitated the study of shoreline changes. Geographical Information System (GIS) alongside Remote Sensing (RS) technology is a useful tool to study these changes due to its ability to generate information, monitoring, analysis and prediction of the shoreline changes. Hence, the future projection of the trend for a specific coastal area can be done effectively. This study investigates the impact of shoreline changes to the community in Selangor area which mainly focus on the physical aspects. This study presents preliminary result using satellite image from SPOT 5 to identify the shoreline changes from the year 1984 to 2013 at Selangor coastal area. Extraction of shoreline from satellite image is vital to analyze the erosion and accretion along the shoreline area. This study shows that a shoreline change for the whole area is a categorized as a medium case. The total eroded and accretion of Selangor area from 1984 to 2013 is 2558 hectares and 2583 hectares respectively. As a result, Kapar, Jugra, Telok Panglima Garang and Kelanang are categorized as high risk erosion area. Shoreline changes analysis provides essential information to determine on the shoreline changes trends. Therefore, the results of this study can be used as essential information for conservation and preservation of coastal zone management.

    In Malaysia, data from the Malaysian Health Ministry showed colorectal cancer (CRC) to be the second most common type of cancer in 2007-2009, after breast cancer. The same was apparent after looking at males and females cases separately. In the present study, the Geographic Information System (GIS) was employed to describe the distribution of CRC cases in Kuala Lumpur (KL), Malaysia, according to socio-demographic factors (age, gender, ethnicity and district). This retrospective review concerned data for patients diagnosed with colorectal cancer in the years 1995 to 2011 collected from the Wilayah Persekutuan Health Office, taken from the cancer notification form (NCR-2), and patient medical records from the Surgical Department, Universiti Kebangsaan Malaysia Medical Centre (UKMMC). A total of 146 cases were analyzed. All the data collected were analysed using ArcGIS version 10.0 and SPSS version 19.0. Patients aged 60 to 69 years accounted for the highest proportion of cases (34.2%) and males slightly predominated 76 (52.1%), Chinese had the highest number of registered cases at 108 (74.0%) and staging revealed most cases in the 3rd and 4th stages. Kernel density analysis showed more cases are concentrated up in the northern area of Petaling and Kuala Lumpur subdistricts.

Data was collected using a mixed method (quantitative and qualitative approach. The questionnaire was disseminated to qaryah mosques in Kuala Terengganu and 39 responded. To address the limitations of a questionnaire survey, semi-structured interviews were then conducted with a few of the respondents. The results revealed that qaryah mosques in Kuala Terengganu do have a satisfactory system in place in terms of their financial reporting practices. However, budgetary control practices appear to be lacking. This indicates accounting, as is practiced by qaryah mosques in Kuala Terengganu appears to be limited to financial accounting. Hence, the financial management in qaryah mosques needs to be improved so that the risk of embezzlement can be reduced.

    Full Text Available Community development emphasizes the utilization of community resources, also known as community capitals. However, it is often difficult for the community to access these resources; this difficulty retards development. Such is the predicament faced by the Orang Kuala, for whom coastal changes have resulted in greater difficulty in accessing their community resources. Nor is that the only threat that they face. For affirmation of these threats, this article lists two objectives, that is, to identify the accessibility of marine resources and to explain the types of threats faced by the Orang Kuala. To achieve these objectives, a study was conducted involving 51 household heads and 5 Orang Kuala informants, all of whom are residents of Sungai Layau village in Johor, Malaysia. This study uses a mixed-method approach, the concurrent embedded design, and also interview-based questionnaires and in-depth interviews simultaneously. For the first objective, the results show that the Orang Kuala can still attain community resources in the form of marine products. However, the Orang Kuala faced three types of threats: trends, shocks, and seasonal changes. The most significant threat to the Orang Kuala is the trend, that is, cost of living and social problems. These threats can reduce their chances of acquiring benefits from these community resources. This condition is called “vulnerability of community capitals.” The objective of this article is to put forth proposals on how to increase the capacity of community resources for the Orang Kuala so that their community can attain sustainable development. This proposal is based on the reality that the threats facing the Orang Kuala are at a critical level and that they are ready to accept changes.

    Full Text Available Cash waqf is becoming one of the popular Islamic financial instruments which not only focus on the religiosity but also has significant impact to the ummah development. This waqf scheme does not require richness in wealth, yet everybody in the society can contribute to cash waqf. The importance of cash waqf is getting popular as it has benefited in many ways, for example it can be used to develop assets and abandoned land for business and agricultural purposes. In addition, cash waqf also can be utilized to help institutions who are facing financial problem or liquidity issues. Nonetheless, rarely we found in the literature that empirically examines the cash waqf determinants and contributions. This paper is one of the few empirical studies that investigate the determinants towards the contribution of cash waqf in Malaysia. The purpose of this paper is to investigate the main factors that influence people towards the contribution of cash waqf instruments, special reference to the Klang Valley and Selangor. This paper employs structural equation modeling (SEM to verify the determinants of cash waqf contribution. In doing so, we use primary data by distributing self-administrated questionnaire constituting a sample of 114 respondents from Klang Valley and Selangor. Our empirical results reveal that the main factors that driven people towards the contribution of cash waqf products are attitude and social influences, however interestingly religion obligation is not influence the contribution of cash waqf.

    Physico-chemical parameters of ricefield water were measured in the Northwest Selangor Project (Project Barat Laut Selangor, PBLS) rice granary area. The physical parameters were similarly measured in several areas of the Muda rice granary area. The temperature, pH and conductivity levels in the Muda rice granary area were significantly different from the PBLS, whereas the differences in turbidity and dissolved oxygen were not significant. The turbidity, temperature and amounts of dissolved oxygen fluctuated over a one year period, whereas the pH and conductivity were relatively stable in Pasir Panjang and Sawah Sempa dan of PBLS. At PBLS, the conductivity and levels of potassium, sodium, manganese, magnesium, iron, aluminium, chromium, cobalt and zinc, as measured in irrigation water were above the normal recommended maximum concentration for waters used continuously on soils or the no restriction limit for irrigation purposes as set by the Food and Agricultural Organisation (FAO). The dissolved oxygen levels and concentration of manganese, iron, aluminium and chromium were above the standardized and optimum properties for aquacultural activities in Malaysia and Japan. The pH of the ricefield water was lower than the values recommended or standardized for irrigation and aquacultural activities. (Author)

    A total of 13 fatty alcohols (C 12 - C 24 ) including six branched compounds have been identified in seven surface sediment samples taken from Sungai Kapar, Selangor using computerized gas chromatography-mass spectrometry (GC-MS). Generally 65 % of total fatty alcohols determined were short chain compounds (C 12 - C 20 ) derived from marine organisms, 14 % were long chained compounds (C 21 - C 24 ) input of terrestrial plants and the rest were branched compounds from bacterial activity. C 16 compound dominated all the sampling stations with concentrations ranged from 29.69 to 164.35 μgg -1 dry weight which constitute 32 % of total fatty alcohols. Short chain/long chain fatty alcohols ratio [Σ(C 12 - C 20 )/ Σ(C 21 - C 22 )] of each sampling stations had the value >1; indicating high content of short chain compounds from marine sources. Meanwhile, Alcohol Source Index (ASI) calculated using C 22 / C 14 and C 22 / C 16 ratios. C 22 / C 14 ratio showed that stations Kp1, Kp2, Kp5 and Kp6 had a value >1 indicating the amount of C 22 was higher than C 14 . Ratio of C 22 / C 16 showed that all the sampling stations dominated by C 16 compared to C 22 . The estuary of Sungai Kapar, Selangor was dominated by short chain fatty alcohols (C 12 - C 20 ) especially C 16 compound rather than long chain fatty alcohol (C 21 - C 24 ). (author)

    To determine the epidemiology of rotavirus gastroenteritis in children admitted to an urban hospital in a developing country from South-East Asia. Retrospective review of cases of acute gastroenteritis admitted to the children's ward of the University of Malaya Medical Centre, Kuala Lumpur, Malaysia, between 1996 and 1999. During the study period, 333 cases (24%) of 1362 stool samples, obtained from children admitted with acute diarrhoea, were positive for rotavirus. Acute gastroenteritis constituted 8.2%, and rotavirus infection 1.6% of all the paediatric admissions each year. Of the 271 cases analysed, 72% of the affected population were less than 2 years of age. Peak incidence of admissions was between January to March, and September to October. Dehydration was common (92%) but electrolyte disturbances, lactose intolerance (5.2%), prolonged diarrhoea (2.6%) and cow's milk protein intolerance was uncommon. No deaths were recorded. Rotavirus infection was a common cause of childhood diarrhoea that required hospital admission in an urban setting in Malaysia.

    A study has been conducted to determine the composition of surfactants in runoff water in the semi-urban area of Bandar Baru Bangi, Selangor, Malaysia. Runoff samples were collected from five different locations with contrasting functional activities and the colorimetric method was used to analyze the concentrations of surfactants as methylene blue active substances (MBAS) for anionic surfactants and as disulphine blue active substances (DBAS) for cationic surfactants. The results showed that the highest surfactant concentrations of MBAS and DBAS in runoff water were recorded in the samples collected at the residential area, with the concentrations of 3.192 ± 0.727 and 0.170 ± 0.028 μmol/L, respectively. Anionic surfactants as MBAS were found to dominate the concentration of surfactants in both runoff and rainwater. The concentrations of both anionic and cationic surfactants in runoff water were recorded as being higher than in rainwater.

    An estuary is an area that has a free connection with the open sea and it is a dynamic semi-enclosed coastal bodies. Ex-mining, aquaculture and industrial areas in Selangor are the sources of pollutants discharged into the estuary water. Radionuclides are considered as pollutants to the estuary water. Gamma radiations emitted by natural radionuclides through their decaying process may give impact to human. The radiological effect of natural radionuclides which are {sup 226}Ra, {sup 228}Ra, {sup 40}K, {sup 238}U and {sup 232}Th, were explored by determining the respective activity concentrations in filtered water along the Langat estuary, Selangor. Meanwhile, in- situ water quality parameters such as temperature, dissolve oxygen (DO), salinity, total suspended solid (TSS), pH and turbidity were measured by using YSI portable multi probes meter. The activity concentration of {sup 226}Ra, {sup 228}Ra and {sup 40}K were determined by using gamma-ray spectrometry with high-purity germanium (HPGe) detector. The activity concentrations of {sup 226}Ra, {sup 228}Ra and {sup 40}K in samples are in the range of 0.17 - 0.67 Bq/L, 0.16 - 0.97 Bq/L and 1.22 - 5.57 Bq/L respectively. On the other hand, the concentrations of uranium-238 and thorium-232 were determined by using Energy Dispersive X-ray Fluorescence Spectrometry (EDXRF). The thorium concentrations are between 0.17 ppm to 0.28 ppm and uranium concentrations were 0.25 ppm to 0.31 ppm. The results show activity concentrations of radionuclides are slightly high near the river estuary. The Radium Equivalent, Absorbed Dose Rate, External Hazard Index, and Annual Effective Dose of {sup 226}Ra, {sup 228}Ra and {sup 40}K are also studied.

    Air pollution is one of the major issues that has been affecting human health, agricultural crops, forest species and ecosystems. Since 1980, Malaysia has had a series of haze episodes and the worst ever was reported in 1997. As a result, the government has established the Malaysia Air Quality Guidelines, the Air Pollution Index (API) and Haze Action Plan, to improve the air quality. The API was introduced as an index system for classifying and reporting the ambient air quality in Malaysia. The API for a given period is calculated based on the sub-index value (sub-API) for all the five air pollutants, namely sulphur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), ozone (O 3 ), carbon monoxide (CO) and particulate matter below 10 micron size (PM 10 ). The forecast of air pollution can be used for air pollution assessment and management. It can serve as information and warning to the public in cases of high air pollution levels and for policy management of many different chemical compounds. Hence, the objective of this project is to fit and illustrate the use of time series models in forecasting the API in Shah Alam, Selangor. The data used in this study consists of 70 monthly observations of API (from March 1998 to December 2003) published in the Annual Reports of the Department of Environment, Selangor. The time series models that were being considered were the Integrated Autoregressive Moving Average (ARIMA) and the Integrated Long Memory Model (ARFIMA) models. The lowest MAE, RMSE and MAPE values were used as the model selection criteria. Between these two models considered, the integrated ARFIMA model appears to be the better model as it has the lowest MAPE value. However, the actual value of May 2003 falls outside the 95% forecast interval, probably due to emissions from mobile sources (i.e., motor vehicles), industrial emissions, burning of solid wastes and forest fires.

    Electrical resistivity and Ground Penetrating Radar (GPR) surveys were carried out at Taman Hill View, Ampang, Selangor landslide area. This landslide site was a part of three similar landslides which occurred at Bukit Antarabangsa, Hulu Klang, Selangor. The landslide had occurred along the road to Bukit Antarabangsa and Athenaeum Tower. The objectives of these studies were to characterise the sliding material and to determine the depth of bedrock below the sliding surface using the electrical resistivity imaging technique as well as to recognise the fractured or weak zone using the GPR technique. The spacing between electrodes used in the survey was 2 to 2.5 m and the survey lines were chosen close to the borehole locations. With a total of 41 electrodes and spacing between each electrode of 2 to 2.5 m, the maximum current electrode spacing in this survey would be between 80-100 m resulting in the deepest subsurface depth investigated approximately at 20 to 25 m. A 100 MHz electromagnetic wave was used in the Ground Penetration Radar survey. The resistivity imaging result showed the weathered granite profile with resistivity value ranging from 2 to 7000 Ωm. The patterns also show that this area had a lot of fractured or weak zones up to a depth of 4 to 5 m based on the occurrence of low resistivities zones in between the high resistivities. These highly fractured and faulted zones also appeared in the GPR sections as shown by the presence of shifted reflectors and layer discontinuity. (author)

    Arsenic and 5 heavy metals (nickel, copper, zinc, cadmium and lead) were quantitated in surface water (n = 18) and soil/ore samples (n = 45) collected from 5 land uses (oil palm converted from forest, oil palm in peat swamp, bare land, quarry and forest) in the Selangor River basin by inductively coupled plasma mass spectrometry (ICP-MS). Geographic information system (GIS) was used as a spatial analytical tool to classify 4 land uses (forest, agriculture/peat, urban and bare land) from a satellite image taken by Landsat 8. Source profiling of the 6 elements was conducted to identify their occurrence, their distribution and the pollution source associated with the land use. The concentrations of arsenic, cadmium and lead were also analyzed in maternal blood (n = 99) and cord blood (n = 87) specimens from 136 pregnant women collected at the University of Malaya Medical Center for elucidating maternal exposure as well as maternal-to-fetal transfer. The source profiling identified that nickel and zinc were discharged from sewage and/or industrial effluents, and that lead was discharged from mining sites. Arsenic showed a site-specific pollution in tin-tungsten deposit areas, and the pollution source could be associated with arsenopyrite. The maternal blood levels of arsenic (0.82 ± 0.61 μg/dL), cadmium (0.15 ± 0.2 μg/dL) and lead (2.6 ± 2.1 μg/dL) were not significantly high compared to their acute toxicity levels, but could have attributable risks of chronic toxicity. Those in cord blood were significantly decreased in cadmium (0.06 ± 0.07 μg/dL) and lead (0.99 ± 1.2 μg/dL) but were equivalent in arsenic (0.82 ± 1.1 μg/dL) because of the different kinetics of maternal-to-fetal transfer.

    A survey was conducted in December 1995 to study car occupant restraint usage in Selangor. A total of 1082 car occupants were observed in 536 cars. The results of the study shows that only 57.3% of the car occupants observed were protected by any form of restraints. Most of the cars (99.8%) examined had front seat belts but only 44.2% had rear seat belts. Only 0.6% of the cars were found to have child restraints in the cars. 80.2% of drivers used restraints and only 65.4% of front seat passengers used any forms of restraints. In the case of the rear seat passengers, only 0.42% used an available restraint. More people in the urban areas (84.42%) than in the rural areas (66.51%) used seat belts. Usage of seat belts by car drivers influenced the use of seat belts by front seat passengers. Type of seat belts fitted was associated with usage rate. It is sad to note that 21.9% of the drivers used seat belts incorrectly.

    Poor sleep quality among adolescents is becoming a major worldwide concern and is widely recognized as a significant public health issue. To determine the prevalence and predictors of poor sleep quality among secondary school students in Gombak District, Selangor. A cross-sectional study was conducted in Gombak District. The sample size was 1,092 based on two group comparison formula. Students were selected using sampling with probability to proportionate to size. Selfadministered pretested questionnaires were used to collect the data. The data were analysed using the Statistical Package for Social Sciences (SPSS) version 22. Chi-square or Fisher's exact test was performed to determine the association between individual categorical variables and sleep quality. Variables with p-value sleep quality was 24.0% (95% CI = 21.5, 26.6). Based on the analysis of simple logistic regression seven variables that were significantly associated with poor sleep quality were age, gender, marital status of parents, depression, anxiety, stress and academic performance found fit in the model. Multivariate logistic analysis showed that the significant predictors of poor sleep quality were age, marital status of parents, depression, anxiety, stress and academic performance. Factors that were not statistically significant were gender, religion, ethnicity, parent's educational level and family income. Prevalence of poor sleep quality among adolescents is high. The predictors of poor sleep quality are age, marital status of parents, depression, anxiety, stress and academic performance.

    A cross-sectional study was conducted among form four students of secondary schools in the District of Petaling, Selangor, Malaysia from February 2008 to June 2008 with the aim of quantifying the prevalence of smoking and identifying the psychosocial factors related to smoking among adolescents in this district. A two-stage stratified sampling strategy was used to obtain a sample of 1300 students based on an estimated prevalence of 10%. The response rate was 80.5% (1045 out of 1298 students). Results showed that prevalence of smoking was higher among male students (22.3%) compared to females (5.5%) and the median age at smoking initiation was lower among males compared to female smokers (14 years old vs 15 years old). Modifiable risk factors associated with smoking were "percentage of friends who smoke" (OR 2.94, 95% CI [1.71- 5.06]) and "having a brother who smokes" (OR 1.97, 95% CI [1.20-3.31]). There was also a correlation between smoking prevalence and the number of risk factors present. Intensification of health education and anti-smoking programmes and modification of external factors in early adolescence are recommended to prevent smoking initiation.

    This study aims to determine the prevalence of protein-energy malnutrition and its association with soil-transmitted helminthiases in Orang Asli (Aborigine) children in Selangor, Malaysia. The results obtained from 368 children aged 2-15 years showed that the overall prevalence of mild and significant underweight was 32.1% and 56.5% respectively. The prevalence of mild stunting was 25.6% while another 61.3% had significant stunting. The overall prevalence of mild and significant wasting was 39.0% and 19.5% respectively. The overall prevalence of ascariasis, trichuriasis and hookworm infection were 61.9%, 98.2% and 37.0% respectively and of these 18.9%, 23.5% and 2.5% of the children had severe infection of the respective helminthes. The overall prevalence of giardiasis was 24.9%. The present study vividly shows that stunting and underweight are highly prevalent among Orang Asli children and therefore of concern in this community. In this population intestinal parasitic infections, especially severe trichuriasis and giardiasis, were identified as the main predictors of stunting and wasting respectively, in addition to age between 2 to 6 years.

    This research was performed to determine the prevalence of iodine deficiency disorder (IDD) and the effects of iodized salt supplementation on thyroid status amongst Orang Asli in Hulu Selangor, Malaysia. Study respondents were from three target groups, i.e. pre-school children (PSC), primary school-going children (SGC) and adult women. Each household was supplied with iodized salt fortified with iodate fortificant for a period of 12 months and the iodine levels in the salt ranged from 20 to 30 μg/L. Samples collected before and after 6 and 12 months of introduction to iodized salt were urine from all groups, as well as serum samples from adult women. A total of 200 respondents were recruited; 58 (29.0%) PSC, 65 (32.5%) SGC and 77 (38.5%) adult women. The median urine-iodine concentration (mUIC) in all groups were of moderately low before the iodized salt intervention, but increased significantly in all study groups after 6 and 12 months of intervention. However, at the end of the study, there was an increase in severe iodine deficiency (mUIC Orang Asli. However, an increase in severe iodine deficiency and iodine excess indicated that the iodized salt programme needs to be carefully monitored.

    Composition of fatty alcohols from 19 surface sediment samples collected along Sungai Sepang Besar, Sepang, Selangor were determined. The sediments were extracted and analysed using the Gas Chromatography-Mass Spectrometry (GC-MS) technique. A total of 19 fatty alcohols from C 12 to C 30 including 4 branched compounds were identified with concentrations in the range 0.02 μg/ g - 9.01 μg/ g dry weight. C 26 fatty alcohols dominated most sampling stations with concentrations ranging from 0.29 to 5.43 μg/ g dry weight and constituted 15.5 % of total fatty alcohols. According to individual compounds of fatty alcohols and the [Σ(C 12 - C 20 )/ Σ(C 22 - C 30 )] ratio, Sungai Sepang Besar has a high composition of short-chain fatty alcohols (C 12 - C 20 ) which mainly originate from marine organisms. However, the Alcohol Sources Index (ASI) showed that terrestrial derived fatty alcohols dominated the area due to high concentration of C 26 compounds in most sampling stations. The value of (odd chain length)/ (even chain length) ratios were high for almost all the sampling stations due to high bacterial activities. It can be concluded that the surface sediments of Sungai Sepang Besar contained organic materials from marine, terrestrial and bacterial sources. (author)

    Official reports of child maltreatment in Malaysia have persistently increased throughout the last decade. However there is a lack of population surveys evaluating the actual burden of child maltreatment, its correlates and its consequences in the country. This cross sectional study employed 2 stage stratified cluster random sampling of public primary schools, to survey 3509 ten to twelve year old school children in Selangor state. It aimed to estimate the prevalence of parental physical and emotional maltreatment, parental neglect and teacher- inflicted physical maltreatment. It further aimed to examine the associations between child maltreatment and important socio-demographic factors; family functioning and symptoms of depression among children. Logistic regression on weighted samples was used to extend results to a population level. Three quarters of 10-12 year olds reported at least one form of maltreatment, with parental physical maltreatment being most common. Males had higher odds of maltreatment in general except for emotional maltreatment. Ethnicity and parental conflict were key factors associated with maltreatment. The study contributes important evidence towards improving public health interventions for child maltreatment prevention in the country.

    Full Text Available Oil palm plantations on peat soils are generally believed to have greater environmental impacts than those on other soil types. Nonetheless, Malaysia operates substantial incentives to maximise palm oil production, which in practice encourage the establishment of plantations on peatland. This paper explores the social and economic basis of oil palm cultivation on one peatland estate at Sungai Panjang in the state of Selangor, peninsular Malaysia. Data were obtained by conducting a questionnaire survey of 200 farmers who cultivate oil palm on peat soil. Some of the data were cross-tabulated against farmers’ ages in order to identify any age-related trends in education level, the area of land farmed, annual income and knowledge about oil palm cultivation. The Cobb-Douglas production function was used to model the financial output from oil palm in terms of the costs of chemical inputs and labour. The results indicated that cultivation of this crop gives decreasing returns to scale on peatland in Sungai Panjang, and that chemical inputs are more important than labour cost in determining the level of financial output. Finally, the financial viability of oil palm cultivation for farmers was assessed by calculating three financial indicators (NPV, BCR and IRR. This can be a profitable investment so long as growth conditions, costs, selling price and interest rate do not fluctuate substantially. Greater annual returns can be achieved over 20–25 years than over shorter periods, especially of less than 10 years.

    A study on benthic macroinvertebrates diversity and water quality assessment was conducted at Sungai Congkak recreational area in Hulu Langat, Selangor. Sums of eight sampling stations were selected with a distance of 100-200 m interval between each station. Benthic macroinvertebrates was sampled using a Surber net, while water sampling and analysis were undertaken according to HACH standard methods. A total of 3754 individuals from 40 families of benthic macroinvertebrates were recorded at this river. Ecological indices namely Shannon diversity index (2.49), Pielou evenness index (0.77) and Margalef richness index (4.06) demonstrate that Sungai Congkak is at good condition and benthic macroinvertebrates has homogeneous distribution along the sampling sites. Elmidae, Hydrophilidae, Baetidae and Perlidae were most dominant families present in that area and adapted progressively with excellent water quality (> 300 individuals). As regards to Malaysian's Water Quality Index (WQI), the study area at Sungai Congkak is classified in class I which has good water quality conditions. The Pearson correlation test indicates that ecological indices have strong correlation toward WQI at all sampling stations. As a conclusion, the benthic macroinvertebrates and WQI data demonstrated that Sungai Congkak is clean and suitable as recreational stream based on this study.

    The purpose of this study is to examine some socioeconomic factors that are associated with family planning practice in a metropolitan area of a developing country, namely Malaysia. Data collected during the 1977 Family and Health Survey in Kuala Lumpur and Petaling Jaya is utilized. The study population comprised currently married women aged 15-49 years residing in Kuala Lumpur and Petaling Jaya, the 2 densely populated, rapidly expanding and adjoining metropolitan areas in Peninsular Malaysia. The study population was selected using a 2-stage systematic sampling technique from specifically defined areas in Kuala Lumpur and Petaling Jaya. These areas were selected accourding to socioeconomic criteria, namely, the squatter or slum areas, the new villages located on the periphery of the metropolitan area, other Kuala Lumpur and other Petaling Jaya. Family planning behavior, specifically, contraceptive use is also associated with socioeconomic variables. It is determined that the best predictors of contraceptive use, in order of importance are ethnicity, age and area. However, the relationship between age and contraceptive use varies across ethnic groups. In particular, among Malay and Chinese women, contraceptive use decreases as age increases, but among Indian women usage is not related to age. For the Malay women, usage decreases rapidly after age 24 years but the decline is more gradual for the Chinese women. In general, Chinese women are more likely to be current users in comparison to Malays, while the Indians occupy an intermediate position. The probability of usage is higher for women residing in Petaling Jaya and squatter areas in comparison to those residing in Kuala Lumpur and new villages.

    A total of 20 landfills are located in State of Selangor, Malaysia. This includes the Ampar Tenang landfill site, which was closed on 26 January 2010. It was reported that the landfill has been upgraded to a level I type of sanitary classification. However, the dumpsite area is not being covered according to the classification. In addition, municipal solid waste was dumped directly on top of the unlined natural alluvium formation. This does not only contaminate surface and subsurface soils, but also initiates the potential risk of groundwater pollution. Based on previous studies, the Ampar Tenang soil has been proven to no longer be capable of preventing pollution migration. In this study, metal concentrations of soil samples up to 30 m depth were analyzed based on statistical analysis. It is very significant because research of this type has not been carried out before. The subsurface soils were significantly polluted by arsenic (As), lead (Pb), iron (Fe), copper (Cu) and aluminium (Al). As and Pb exceeded the safe limit values of 5.90 mg/kg and 31.00 mg/kg, respectively, based on Provincial Sediment Quality Guidelines for Metals and the Interim Sediment Quality Values. Furthermore, only Cu concentrations showed a significantly decreasing trend with increasing depth. Most metals were found on clay-type soils based on the cluster analysis method. Moreover, the analysis also differentiates two clusters: cluster I-Pb, As, zinc, Cu, manganese, calcium, sodium, magnesium, potassium and Fe; cluster II-Al. Different clustering may suggest a different contamination source of metals.

    Obesity is a major public health problem in general population and there is no exception for firefighters. This disorder is definitely a burden for firefighters as they needed to be physically fit in order to work in dangerous situation and extinguishing fires. The purposes of this study were to determine physical characteristics and body composition among Malaysian Firefighters (MF) and to explore their association. This cross-sectional study involved 330 rescue firefighters aged between 20-50 years old from nine different districts in Selangor conducted between August and November 2015. Anthropometric measurements included height, weight and waist circumference (WC). Body composition was measured using bioelectrical impedance. The mean height, weight, body mass index (BMI), WC and body fat percentage were 169.4±5.3 cm, 74.5±12.2 kg, 25.9±3.82 kg/m2, 90.7±48.3 cm and 25.8±6.2 % respectively. The results also showed that 0.6% of them were underweight, 41.5% were normal, 44.8% were overweight and 13% were obese. The percentage of 34.8% firefighters with WC values of more than 90 cm means that they were at greater risk to have cardiovascular and diabetes disease. Body composition analysis showed that 75.5% of the subjects have high body fat level, 19.7% subjects were in healthy range but only 4.8% were considered as lean subjects. BMI was highly correlated with weight (r=0.917, page, married, less educated and have longer duration of services. It can be concluded that more than half of the firefighter personnel were either overweight or obese and 35% of them were at greater risk of having non-communicable diseases. This study provides useful information and serves as a source of reference for planning health related program for MF personnel to prevent non-communicable disease among firefighters population.

    Full Text Available Objective: To determine the infestation profile by performing ovitrap surveillance in four types of residential areas in central zone of Shah Alam, Selangor. Methods: 600 ovitraps were exposed for 4 days in intradomiciliary environments within 20 residential areas including independent houses, inter-connected houses, commercial buildings and mixed houses areas. The ecological conditions of the surrounding environment were observed and recorded. The distributions and abundances of the Aedes mosquitoes were presented in terms of positive ovitrap index (POI and mean eggs per trap (MET. One-way ANOVA test was used to determine the association between the type of residential areas and the number of ovitrap with eggs and the egg count. Results: The result implied that Seksyen 7 has the highest reading of both ovitrap index and egg count (POI = 86.21%, MET = 41.68 eggs. There was no significant difference in the POI and MET of Aedes mosquitoes between the type of housing areas (P > 0.05. The surrounding environmental conditions were believed to be the main influence of the abundance and distribution of the Aedes mosquitoes in Shah Alam. Unhygienic conditions were observed in all type of residential areas. These included the abandoned kitchen utensils and flower pots stored at the backyard which lead to collected stagnant water that later served as the favourable places for female Aedes to oviposit. Conclusions: The key to effectively control the dengue outbreak is to have an advance understanding to all the high potential transmission areas or habitat which are generally the areas with the densest human and vector population.

    Lichens have been used as effective biomonitors of atmospheric pollutants as they can take up nutrients and pollutants directly from the atmosphere. In this study, trace element contents in epiphytic lichens were determined using INAA method. Samples were collected from 7 sampling locations around Bandar Baru Bangi, Selangor. The elements detected were As (1.73+0.85 mg/kg), Ce (3.65+1.91 mg/kg), Co (0.29+0.12 mg/kg), Cr (5.92+3.54 mg/kg), Cs (0.92+0.25 mg/kg), Eu (0.03+0.02 mg/kg), Fe (1280+760 mg/kg), Hf (0.37+0.18 mg/kg), La (1.52+0.89 mg/kg), Rb (27.7+4.8 mg/kg), Sc (0.33+0.19 mg/kg), Sm (0.28+0.16 mg/kg), Th (1.21+0.62 mg/kg) and Zn (116+27 mg/kg). Comparisons were then made between the elemental concentrations obtained and the baseline data from literature. Results showed that most of the elements were within the concentration range of the baseline data. Enrichment factors (EF) of the trace element in lichens showed that most of the elements were within the range of the baseline data except for As which was found to be slightly enriched (EF: 13.2 - 28.5). Regression analysis indicated significant correlation (p<0.05) with Sc for most of the elements which signifies crustal input except for Cs and Rb. The poor correlations of Cs and Rb with Sc may be due to the mobility of these elements. In summary, trace element data obtained using INAA were very useful and demonstrated that lichens were suitable biomonitors for identifying potential trace element pollutants in ambient air around the sampling area.

    Full Text Available Muslim counselor in school is a professional guide who can help schools to reduce students’ misbehavior and to implement Islamic values as a way of life. The Islamic approach is the approach implemented by the school counselor in dealing student’s misbehavior. However, the practice of Islamic approach using by Muslim counselor at school in dealing with students’ misbehavior has not been studied extensively. This paper is aimed to discuss and analyze the Islamic approach adopted by the Muslim counselor as an effort to deal the students’ misbehavior in secondary schools in Klang District, Selangor. Data in this paper were collected through a quantitative survey research. By using purposive sampling, a total of 73 Muslim counselors from secondary schools in the Klang District were selected as respondents. Data were analyzed using descriptive statistical techniques. The study shows that Muslim counselor in schools has implemented the Islamic preventive approach through programs such as anti-smoking talks, HIV and AIDS talks, self-identity courses, leadership courses, religious talks, and visiting program to rehabilitation center. This study also shows that Muslim counselor practicing Islamic preventive approach in dealing students’ misbehavior such as guiding students to perform solat fardu five times a day, to respect human being and environment, to behave with persistence, to commit with a good or ma`ruf deed, and to select a good mass media. As a whole, the Islamic preventive approach by the Muslim counselor has given a huge implication especially to develop an Islamic counseling index in dealing students’ misbehavior.

    Comparing nurses and general caregivers' knowledge, attitude, and practices (KAP) on medication administration process in long-term care (LTC) setting and an assessment of their stress, anxiety, and depression (SAD) level. A cross-sectional survey was conducted among nurses and general caregivers working in LTC using a validated questionnaire. Consisting of demographic characteristics (Section 1); 40 questions on KAP (Section 2); and assessment of Depression, Anxiety, and Stress Scale (DASS-21) (Section 3). 155 formally paid staffs in 26 LTC facilities were recruited. Nurses scored significantly higher in the knowledge section compared to caregivers (12.4 ± 1.7 vs. 4.5 ± 3.8; P < 0.001); better attitude (41.5 ± 4.8 vs. 30.8 ± 7.3; P < 0.001); and better practice (65.2 ± 8.5 vs. 40.3 ± 10.9; P < 0.001), respectively. SAD scores reveal that caregivers had significantly higher level of stress, anxiety, and depression compared to the nurses. General caregivers exhibit poorer knowledge on aspects pertaining to posology, appropriate methods of drug administration, and side effects of common drugs used by the elderly. Compared to nurses, the general caregivers also reported poorer medication administration practices; including not checking labels and expiry dates prior to administration, and not providing basic information about medication therapy to the residents. However, both nurses and general caregivers reported positive attitudes in their role as caregivers. They take pride and satisfaction in their occupation providing support to the elderly. General caregivers demonstrated lesser knowledge, poorer attitude, and practices towards medication administration processes, in addition to higher SAD score in LTC facilities.

    In the last few years in Malaysia, dengue fever has increased dramatically and has caused huge public health concerns. The present study aimed to establish a spatial distribution of dengue cases in the city of Kuala Lumpur using a combination of Geographic Information System (GIS) and spatial statistical tools. Collation of data from 1,618 dengue cases in 2009 was obtained from Kuala Lumpur City Hall (DBKL). These data were processed and then converted into GIS format. Information on the average monthly rainfall was also used to correlate with the distribution pattern of dengue cases. To asses the spatial distribution of dengue cases, Average Nearest Neighbor (ANN) Analysis was applied together with spatial analysis with the ESRI ArcGIS V9.3 programme. Results indicated that the distribution of dengue cases in Kuala Lumpur for the year 2009 was spatially clustered with R value less than 1 (R = 0.42; z-scores = - 4.47; p 1) between August and November. In addition, the mean monthly rainfall has not influenced the distribution pattern of the dengue cases. Implementation of control measures is more difficult for dispersed pattern compared to clustered pattern. From this study, it was found that distribution pattern of dengue cases in Kuala Lumpur in 2009 was spatially distributed (dispersed or clustered) rather than cases occurring randomly. It was proven that by using GIS and spatial statistic tools, we can determine the spatial distribution between dengue and population. Utilization of GIS tools is vital in assisting health agencies, epidemiologist, public health officer, town planner and relevant authorities in developing efficient control measures and contingency programmes to effectively combat dengue fever.

    2017-10-01

    Full Text Available Kuala Lumpur, as a major capital city, has undergone a drastic transformation in the past ten years. Many heritage buildings have been sacrificed for urban renewal projects. Those located in the touristic heritage zones within Kuala Lumpur were being converted by their owners into hotels and cafés to meet current demands to sustain their incomes. This approach, however, creates several physical and environmental issues within the new adaptation. The aim of this study is to evaluate the building performance of heritage shophouses that were adapted into budget hotels. The research focuses on two case studies in a strategic and historical location of Jalan Sultan, Kuala Lumpur. At the initial stage, interviews and physical surveys were done to determine the context of this study. The authors of this research then used a triangulation method through indoor environmental condition assessment, measurements of indoor environmental conditions and occupant survey to determine the indoor building performance after the adaption. Results showed that adaptive reuse heritage buildings can perform and meet new indoor environmental requirements, but many sensitive design judgments need to be made before the adaptive reuse renovation. The research found that the use of natural light, natural ventilation, recycled materials and water efficiency have been neglected and thus, they should be prioritized and preserved to ensure a successful change of use. Conserving existing heritage buildings, while incorporating new usages with acceptable comfort, is in line with the principle of sustainability.

    In Malaysia, rivers are the main source of public water supplies. This study was conducted from 2002 to 2003 to determine the levels of selected organochlorine and organophosphate pesticides in the Selangor River in Malaysia. Surface water samples have been collected seasonally from nine sites along the river. A liquid-liquid extraction followed by gas chromatography-mass spectrometry technique was used to determine the trace levels of these pesticide residues. The organochlorine pesticides detected were lindane, heptachlor, endosulfan, dieldrin, endosulfan sulfate, o,p'-DDT, p,p'-DDT, o,p'-DDE and p,p'-DDE whereas for organophosphate pesticides, they were chlorpyrifos and diazinon. At the river upstream where a dam is located for public water supply, incidents of pesticide levels exceeding the European Economic Community Directive of water quality standards have occurred. Furthermore, the wetland ecosystems located at the downstream of the river which houses the fireflies community is being threatened by occasional pesticide levels above EPA limits for freshwater aquatic organisms. The occurrence of these residual pesticides in the Selangor River can be attributed to the intense agriculture and urban activity.

    This survey evaluated the knowledge, attitudes, and practices of general dental practitioners (GDPs) in Selangor regarding early childhood caries (ECC) prevention and the recommended timing of a child's first dental visit. A questionnaire was mailed to 521 licensed GDPs. Descriptive statistics were used, and bivariate and logistic regression analyses were performed. The response rate was 52.6%. Although 89.8% mentioned counseling parents and caregivers, only 44.2% were familiar with anticipatory guidance. Whereas 98.2% agreed that early examinations are important to prevent ECC, only 51.8% were aware of the recommendation for a first visit by 12 months of age. GDPs who recommended early dental visits were significantly more likely to be recent graduates, more familiar with professional guidelines, and less likely to be deterred by a child's crying or behavior. In conclusion, GDPs in Selangor are aware about the importance of early dental visits in ECC prevention. However, a considerable number of them are still not aware of the recommendation that children must first visit the dentist by 12 months of age. Furthermore, some of their current practices in ECC management and prevention do not match professional recommendations. © 2013 APJPH.

    This study focuses on the levels of heavy metals in seawater and selected fish tissue at Pulau Indah, Selangor, Malaysia. Pulau Indah primarily contains Westport (Malaysia's major port), and a host of full scales factories. Therefore, it is important to monitor the levels of pollution in this water body and the aquatic organisms in the long term effects, due to the human activities in this area. Water samples in this study were taken from 8 locations along the coastal area. The water samples were collected using water sampler and sampling locations were determined using a Global Positioning system (GPS). Similarly, in situ water quality parameters including temperature, dissolve oxygen (DO), salinity, total suspended solid (TSS), pH and turbidity were measured by using portable multi probes meter. Then, the samples were acidified until pH 2 and filtered. Fish samples were purchased from local fisherman along the Pulau Indah coastal area and samples were digested using concentrated nitric acid in wet digestion method. The levels of selected heavy metals in four species of fish and seawater from Pulau Indah coastal area were determined using Inductive Coupled Plasma Mass Spectrometer (ICPMS) after dilution to the samples. In general, the quality of water at Pulau Indah is lower than Malaysia Marine Water Quality Standard except for few locations were higher than the maximum permissible levels. The concentration of heavy metals which are lead (Pb), copper (Cu), zinc (Zn) and uranium (U) in water samples are in the range of 0.36-5.43 µg/L, 75.20-621.58 µg/L, 11.92-30.52 µg/L, and 4.00-4.65 µg/L respectively. While the results of the four selected fish showed the following order of abundance Zn> U> Cu> Pb. Transfer factor (TF) of heavy metals in fish tissue of selected fish species from the water was discussed. However, the observed metal concentration in the sample tissue did not exceed the allowable limit of Malaysian Food Act (1983) and Regulation (1985

In other word, inaccurate image have been promoted from the view of supply-side rather than from demand-side (tourist. From the view of demand side, it was known in the existing literature that most of the tourism image studies focusing on measuring tourist perceived image using the idea of ‘before and after’ visitation (pre-visit and post-visit. However, a question arise as to how these efforts really capturing the actual image while tourist experiencing the site (during visit. In this context, the advancement in internet and sharing media technology using phone application increase the possibility in capturing ‘real time’ image or actual perceived image during the visit. One of them is using Volunteer Employed Photographer (VEP technique. VEP give advantage in reducing cost of labor and equipment to collect the data since the respondent itself acting as a labor by using their own device to capture the image. The innovation and trend on smart phone for instance, allow tourist to capture high resolution photo and instantly shared. VEP in this case is a form of method in data collection that allow qualitative analysis in order to explore in depth the nature and formation of destination image. As Kuala Lumpur targeting to become a world class business city destination, an ideal destination image is critical and actual image will be able to portray correct positioning of the city tourism according to tourist perspective.

    Most of the landfills in Malaysia are situated near to the main river basin that supplies almost 90% of water requirement. This includes landfills in Selangor where a total of 20 landfill sites are situated in 5 main river basins and the highest number of operating landfills (three) are at the Selangor River Basin (Jeram, Bukit Tagar and Kuang Inert landfills). This situation has caused wide concern over the water safety, even the leachate has been treated. The leachate itself still contains contaminants that are difficult to treat. The main objective of this study is to investigate the effect on water quality of Sembilang River that receives effluent from the nearby landfill. In this study, we analyzed samples of water from ten sampling stations starting from the upstream to downstream of Sembilang River. The water quality was evaluated by the Water Quality Index (WQI) depending on in-situ and laboratory analysis. 11 water quality variables are selected for the quality assessment; temperature, pH, turbidity, salinity, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total suspended solid, ammoniacal nitrogen, phosphate and nitrate. The result indicated that, when the effluent mixed with the river water, the water quality decreased gradually and was found to be lower at a few stations. The water quality of Sembilang River falls under Class III of Water Quality Index with ranges between 68.03 to 43.46 mg/L. It is revealed that the present scenario of water quality of Sembilang River is due to the effect of effluent from the landfill.

    A study was done on 76 suicide cases managed by the Forensic Pathology Department of Hospital Kuala Lumpur (HKL) from January till December 1999 to explore the pattern of suicide and psychiatric history. The Chinese contributed 52% (n=40) of cases followed by the Indians (29%, n=22) and the Malays (12%, n=9). After the age of sixty, 84.6% of the subjects were Chinese. The common methods of suicide were poisoning (39%), hanging (34%) and jumping from height (22%). Four out of 12 case-notes traced had documented psychiatric history i.e. schizophrenia. the suicide rate for Kuala Lumpur is estimated at 7.4 per 100,000. The Indians has the highest suicide rate of 21.1 per 100,000 in keeping with other local studies. The suicide rate for the Chinese is 8.6 per 100,000, but it increased to 23 per 100,000 among the elderly Chinese. The suicide rate for Malays is 2.6 per 100,000, higher than what was cited in previous local studies. The incidence of jumping from height as a suicide method had doubled over the last 2 decades.

    Acts of self-harm are not routinely tracked in Malaysia. The present study investigates the prevalence of self-harm in Kuala Lumpur, Malaysia, over a 7-year period. The aims were to: (a) assess the prevalence of self-harm; (b) examine any changes over a period of 7 years, and (c) identify correlates of methods of self-harm. Data were extracted from the hospital records of Kuala Lumpur Hospital to review trends in self-harm between 2005 and 2011. There were 918 episodes of self-harm across the 7-year period, with a significant peak in 2007-2009. The average rate of self-harm (7.7 per 100,000 population per year) was similar or lower than the rate of suicide (6-8 or 8-13 per 100,000) suggesting that genuine cases of self-harm are often attributed to other causes. Nevertheless, over-representation of young people, women and Indians suggest areas in which resources to prevent self-harm might usefully be targeted. Estimating rates of self-harm are fraught with problems and further research is needed to understand the economic and cultural barriers around seeking treatment for self-harm, reporting self-harm and classifying self-harm.

  12. Suburban sprawl in the developing world: duplicating past mistakes? The case of Kuala Lumpur, Malaysia.

    Science.gov (United States)

    Loh, Lawrence C; Brieger, William B

    Newly affluent developing world cities increasingly adopt the same unfortunate low-density suburban paradigm that shaped cities in the industrialized world. Identified by a World Bank report as a "mini-Los Angeles," Kuala Lumpur is a sentinel example of the results of unrestrained sprawl in the developing world. Factors driving sprawl included government policies favoring foreign investment, "mega-projects," and domestic automobile production; fragmented governance structures allowing federal and state government influence on local planning; increasing middle-class affluence; an oligopoly of local developers; and haphazard municipal zoning and transport planning. The city's present form contributes to Malaysia's dual burden of disease, with inner-city shantytown dwellers facing communicable disease and malnutrition while suburban citizens experience increasing chronic disease, injury, and mental health issues. Despite growing awareness in city plans targeted toward higher density development, Kuala Lumpur presents a warning to other emerging economies of the financial, societal, and population health costs imposed by quickly-built suburban sprawl.

    Vehicular traffic congestion occurs when a large number of drivers are overcrowded on the road and the traffic flow does not run smoothly. Traffic congestion causes chaos on the road and interruption to daily activities of users. Time consumed on road give lots of negative effects on productivity, social behavior, environmental and cost to economy. Congestion is worsens and leads to havoc during the emergency such as flood, accidents, road maintenance and etc., where behavior of traffic flow is always unpredictable and uncontrollable. Real-time and historical traffic data are critical inputs for most traffic flow analysis applications. Researcher attempt to predict traffic using simulations as there is no exact model of traffic flow exists due to its high complexity. Open Traffic is an open source platform available for traffic data analysis linked to Open Street Map (OSM). This research is aimed to study and understand the Open Traffic platform. The real-time traffic flow pattern in Kuala Lumpur area was successfully been extracted and analyzed using Open Traffic. It was observed that the congestion occurs on every major road in Kuala Lumpur and most of it owes to the offices and the economic and commercial centers during rush hours. At some roads the congestion occurs at night due to the tourism activities.

    Full Text Available Language choice in mixed marriages plays a crucial role in language maintenance. It helps in maintaining at least one or two languages from generation to generation. In this study an examination on the language choice of some Sino-Indian Malaysians in Kuala Lumpur, Malaysia, is explored to find out the language choice in a range of domains and with different speech partners. Sino-Indians are the offspring of marriages between Indians and Chinese. There were 30 participants consisting of 14 males and 16 females who took part in the study. A questionnaire consisting of 89 items was administered to the participants who were working or studying in Kuala Lumpur at that time. The findings reveal that language choice in some Sino-Indian families is influenced by factors such as age, domains of communication, attitudes towards the language, and identity. Age plays an important role in lan¬guage choice, particularly in the home domain. Some older Sino-Indian speakers are bilingual in English and Malay, the middle-aged speakers are trilingual and speak more in English and some Tamil and Chinese, and the younger speakers are multilingual but favour the use of English. This study has also examined how the Sino-Indian respondents viewed their dual heritage.

    A colorectal cancer screening program was piloted in two districts of Kedah in 2013. There is scarcity of information on colorectal cancer screening in Malaysia. Thus, this research was conducted to evaluate the colorectal cancer screening program in the districts to provide insights intop its efficacy. A cross sectional study was conducted using data on the colorectal cancer screening program in 2013 involving Kota Setar and Kuala Muda districts in Malaysia. We determined the response rate of immunochemical fecal occult blood test (iFOBT), colonoscopy compliance, and detection rates of neoplasia and carcinoma. We also compared the response of FOBT by demographic background. The response rate of FOBT for first iFOBT screening was 94.7% while the second iFOBT screening was 90.7%. Participants from Kuala Muda district were 27 times more likely to default while Indians had a 3 times higher risk of default compared to Malays. The colonoscopy compliance was suboptimal among those with positive iFOBT. The most common finding from colonoscopy was hemorrhoids, followed by tubular adenoma. Detection rate of carcinoma and neoplasia for our program was 1.2%. In summary, the response rate of iFOBT was encouraging but the colonoscopy compliance was suboptimal which led to a considerably low detection rate.

    The contamination of heavy metals gives bad implications to the aquatic environment. Thus, a study was conducted to assess the sediment quality by using different contamination indices such as Enrichment Factor (EF), Geo-accumulation Index (Igeo), and Pollution Load Index (PLI). Each sediment sample was collected at the surface (0-15cm) at 5 locations based on the land use activity; jetty port (A), seaside restaurant (B), roadside area (C), power plant (D) and residential area (E). All samples were undergoes acid digestion and analyzed with AAS. Four elements identified from the sediment samples which are Cr, Cu, Pb and Zn were used to calculate the respective indices. Results show that, the highest EF value of Pb which categorized as very severe enrichment was at point E. Meanwhile minor enrichment was detected at point B for Cu while Cr and Zn at point A. Based on Igeo value the sediment quality along Kuala Perlis was in the unpolluted-moderately polluted condition (class 1). As for PLI it shows that the sediment of the coastal area is unpolluted (PLIheavy metals in this area is Pb while the sediment quality of Kuala Perlis was in minor pollution condition.

    Sufficient intake of calcium during childhood is very important to ensure an optimal growth and strong bones development. However, lactose intolerance (LI) may limit the intake of milk and dairy products due to the inability of the body to digest lactose to its constituents, glucose and galactose. Children in rural area were a major concern as they are commonly associated with an inadequate intake of nutrients. Hence, the objectives of this study are to determine the prevalence of LI among Malay and Orang Asli female children in rural Selangor and its association with bone mineral density (BMD). A total of 65 (39 Malay, 26 Orang Asli) female primary school students with a mean age of 10.4 ± 0.6 years old underwent hydrogen breath test and lactose tolerance test (LTT) during fasting and after ingestion of 25g lactose solution. A Wong Baker Face Pain Rating Scale (WBFPRS) was used to assess the presence of gastrointestinal (GI) symptoms during the study. LI symptoms are defined when breath H2 levels exceed 20 ppm above baseline values, an increase of postprandial blood glucose (PBG) levels of less than 1.1 mmol/L and GI symptom score is more or equal than score 2. BMD was measured in the calcaneus using QUS-2 Ultrasonometer. The result showed that 35 subjects (15 Malay, 20 Orang Asli) had a positive breath test (>20ppm). A total of 74.4% Malay and 88.5% Orang Asli children had an increase of PBG of less than 1.1 mmol/L. Both groups have low percentage (35.9 % Malay, 34.6 % Orang Asli) of GI symptoms. A total of 20.0% children (n=13, Malay=4, Orang Asli=9) was found to experience LI. Orang Asli children showed a significantly higher (p<0.001) BMD (95.7 ± 11.0 dB/MHz) compared to Malay children (71.7 ± 8.6 dB/MHz). The result shown there is an association between LI with BMD (p=0.031). Hence, LI does affect in decreasing an individual BMD. In conclusion, the prevalence of LI among female children in rural Selangor is low. However, the relationship between LI and BMD

    Inconsistent literature evidence suggests that sociodemographic, economic, and system- and patient-related factors are associated with clinic attendance among the HIV-positive population receiving antiretroviral therapy (ART) around the world. We examined the factors that predict outpatient clinic attendance among a cohort of HIV-positive patients initiating ART in Selangor, Malaysia. This cross-sectional study analyzed secondary data on outpatient clinic attendance and sociodemographic, economic, psychosocial, and patient-related factors among 242 adult Malaysian patients initiating ART in Selangor, Malaysia. Study cohort was enrolled in a parent randomized controlled trial (RCT) in Hospital Sungai Buloh Malaysia between January and December 2014, during which peer counseling, medication, and clinic appointment reminders were provided to the intervention group through short message service (SMS) and telephone calls for 24 consecutive weeks. Data on outpatient clinic attendance were extracted from the hospital electronic medical records system, while other patient-level data were extracted from pre-validated Adult AIDS Clinical Trial Group (AACTG) adherence questionnaires in which primary data were collected. Outpatient clinic attendance was categorized into binary outcome - regular attendee and defaulter categories - based on the number of missed scheduled outpatient clinic appointments within a 6-month period. Multivariate regression models were fitted to examine predictors of outpatient clinic attendance using SPSS version 22 and R software. A total of 224 (93%) patients who completed 6-month assessment were included in the model. Out of those, 42 (18.7%) defaulted scheduled clinic attendance at least once. Missed appointments were significantly more prevalent among females (n=10, 37.0%), rural residents (n=10, 38.5%), and bisexual respondents (n=8, 47.1%). Multivariate binary logistic regression analysis showed that Indian ethnicity (adjusted odds ratio [AOR

    Full Text Available Previously, one of the vital tasks of  English learning is to find new methods and resources to make the EFL students more stimulating and productive. Recently, the usage of movies (in DVD format in courses became popular or supplementary resources to learn English among EFL learners. Many researchers stated that authentic video is an advantage and inspiring tool in language learning. However, there have been quite few studies on the relationship between effective learning and students’ movie preferences. This research aims at finding the relationship between effective learning and students’ movie preferences. To this end, data were collected by using posttests. Participants were students from a Iraqi school in Kuala Lumpur. The researchers uncovered that the participants had insight into the subtitles/captions which are used in the movie in classrooms. The implications of these findings and suggestions are discussed. Keyword: Movie, learning language, vocabularies, implications

    The urban boundary layer (UBL) is the internal advection layer of atmosphere above urban region which determines the exchanges of momentum, water and other atmospheric constituents between the urban land surface and the free troposphere. This paper tested the performance of three planetary boundary layer (PBL) physics schemes of Weather Research and Forecast (WRF) software to ensure the appropriate representation of vertical structure of UBL in Greater Kuala Lumpur (GKL). Comparison was conducted on the performance of respective PBL schemes to generate vertical and near-surface weather profile and rainfall. Mellor-Yamada- Janjíc (MYJ) local PBL scheme coupled with Eta MM5 surface layer scheme was found to predict the near-surface temperature and wind profile and mixing height better than the nonlocal schemes during the intermonsoonal period with least influences of the synoptic background weather.

    Full Text Available The lack of visibility and the difficulty in developing a cognitive map may be particularly important in wayfinding and in categories where the use of accessibility and sociability will provide a square suggestion in the Kuala Lumpur City Center Park (KLCC. This study attempted to examine the existing structure within the vicinity of KLCC and the transformations of its vicinity based on a square suggestion through morphological analysis using axial analysis and observations. The axial analysis shows how the accessibility of the square has shifted within the city and compares it with an existing park. Moreover, a square suggestion can provide context for the Petronas Twin Towers as a landmark and symbolic building. A square, as a regular geometry, can aid in improving the configuration of the vicinity of KLCC. Consequently, this research is useful to architects, tourism managers, and urban designers because it demonstrates the importance of effective factors in sustaining accessible and sociable space, such as a square.

    Entamoeba histolytica infection is the third-greatest parasitic disease responsible for death in the world. Wild rats harbouring E. histolytica can be the possible reservoir hosts for human amoebiasis. There were numerous studies on prevalence of intestinal parasites among wild rats in Malaysia but none has reported E. histolytica. Rats were captured from Sentul and Chow Kit areas, Kuala Lumpur, Malaysia. The preserved stool samples were used for microscopy examination and molecular analysis. Out of 137 samples collected, 12 were positive for E. histolytica / E. dispar / E. moshkovskii microscopically. Two E. histolytica (1.4%), 1 E. dispar (0.7%) and 6 mixed infections of E. histolytica and E. dispar (4.3%) were detected using PCR. This is the first report of molecular detection of E. histolytica/dispar infection among wild rats in Malaysia. This study provides useful information about the potential risks of zoonotic agents and the importance of developing control measures to prevent zoonotic transmission.

    Adult-onset dermatomyositis has been found to be associated with underlying malignancies in up to 40% of patients. The aims of this study were to determine the demographic profile, the underlying cancer and outcome in patients with dermatomyositis. This was a retrospective review of 38 patients with dermatomyositis seen over a 12-year period in the Department of Dermatology, Kuala Lumpur Hospital. Of these, 18 (47.4%) had an associated underlying malignancy. The male to female ratio was 2:1. Ten patients (55.6%) were Chinese. The youngest patient encountered was 32 years old. Nasopharyngeal carcinoma (61.1%) was the most common malignancy in our study population. Tumour markers were not useful as the initial screening for malignancies. Thorough screening for malignancy is imperative in adult dermatomyositis especially those above 40 years old.

    Full Text Available Abstract Background The prevalence of parasitic infections among commensal animals such as black and brown rats in many tropical countries is high and in comparison with studies on rodents in temperate climates, little is known about the community structure of their parasites. Rodent borne parasites pose threats to human health since people living in close proximity to rodent populations can be exposed to infection. Methods The helminth community structures of two urban rat populations in Kuala Lumpur, Malaysia were investigated. The rats were from two contrasting sites in the city caught over a period of 21 months in 2000-2002. Results Eleven species of helminth parasites comprising seven nematodes (Heterakis spumosum, Mastophorus muris, Nippostrongylus brasiliensis, Syphacia muris, Pterygodermatites tani/whartoni, Gongylonema neoplasticum, Angiostrongylus malaysiensis, three cestodes (Hymenolepis (Rodentolepis nana, H. diminuta and Taenia taeniaeformis and one acanthocephalan (Moniliformis moniliformis were recovered from 346 Rattus rattus and 104 R. norvegicus from two urban sites, Bangsar and Chow Kit, during 2000-2002. Rattus rattus harboured over 60% of all helminths compared with R. norvegicus, although both host species played a dominant role in the different sites with, for example R. norvegicus at Bangsar and R. rattus at Chow Kit accounting for most of the nematodes. Overall 80% of rats carried at least one species of helminth, with the highest prevalences being shown by H. diminuta (35%, H. spumosum (29.8% and H. nana (28.4%.

    Full Text Available Introduction: Polio vaccination rates remain low in certain regions of Malaysia. The Federal Territory of Kuala Lumpur (FTKL reported coverage of only 29.3% in 2005 and 61.2% in 2006, despite a Department of Health campaign to provide free three-round immunizations. The estimated numbers of live births used to calculate these rates may have artificially lowered the reported coverage percentages.Methods: A descriptive, cross-sectional household survey was conducted throughout the FTKL in 2007 to assess the actual polio vaccination status of children aged 9 to 24 months. Minimum sample size was calculated and proportionately divided among the 11 FTKL parliamentary constituencies. Residential areas were then randomly selected for in-person interviews. We used the gathered information, verified by medical records, to calculate the actual vaccination coverage and to compare the rates determined by using estimated or registered live births for the region.Results: Of the 1713 study participants, 98.3% had completed their polio vaccination schedule. Only 21 children had been partially vaccinated, and nine children were completely unvaccinated. FTKL residents had 20 431 live births registered for 2006, as opposed to the official estimate of 28 400. When the registered value of live births was used to calculate vaccination coverage, the 2006 coverage increased (to 85.1%.Conclusion: Actual vaccination coverage in Kuala Lumpur was much higher than the estimated coverage previously reported, reflecting the expected success of the Department of Health immunization campaign. Estimated values of live births are insufficient to accurately determine vaccine status and should be avoided.

    Identifying roles for anal sex is an important issue for populations of MSM. We describe the prevalence of identifying as being 'top', 'bottom', 'versatile', or 'don't know/not applicable' among Malay and Chinese MSM in Kuala Lumpur, Malaysia, and behavioural outcomes according to these labels for sexual role identity. Data analysis was conducted on a survey administered during weekly outreach throughout Kuala Lumpur in 2012. Pearson's Chi square tests were used to compare demographic and behavioural characteristics of MSM who reported roles for anal sex. Binary logistic regression was used to explore the odds of behavioural outcomes among MSM who identified as 'bottom', 'versatile,' and 'don't know' compared to MSM who reported that 'top' was their sexual role. Labels for anal sex roles were significantly associated with condom use for last anal sex. Among MSM who used labels for anal sex roles, MSM who identified as 'bottom' had highest level of not using condoms for last anal sex (24.1%, p = .045). In binary logistic regression model, identifying as 'top' was significantly associated with reporting using a condom during last anal sex and reported consistent condom use for anal sex in the past six months (p = .039 and .017, respectively). With regard to sexual role identity, some MSM may be a part of a special subgroup of at-risk men to be targeted. Future research should evaluate the origins, meanings, and perceptions of these labels, and the developmental process of how these MSM identify with any of these categories. Research should also uncover condom use decision making with regard to these labels for sexual positioning. © The Author(s) 2016.

    Red rice is a fermented product of Monascus spp. It is widely consumed by Malaysian Chinese who believe in its pharmacological properties. The traditional method of red rice preparation disregards safety regulation and renders red rice susceptible to fungal infestation and mycotoxin contamination. A preliminary study was undertaken aiming to determine the occurrence of mycotoxigenic fungi and mycotoxins contamination on red rice at consumer level in Selangor, Malaysia. Fifty red rice samples were obtained and subjected to fungal isolation, enumeration, and identification. Citrinin, aflatoxin, and ochratoxin-A were quantitated by ELISA based on the presence of predominant causal fungi. Fungal loads of 1.4 × 10(4) to 2.1 × 10(6) CFU/g exceeded Malaysian limits. Monascus spp. as starter fungi were present in 50 samples (100%), followed by Penicillium chrysogenum (62%), Aspergillus niger (54%), and Aspergillus flavus (44%). Citrinin was present in 100% samples (0.23-20.65 mg/kg), aflatoxin in 92% samples (0.61-77.33 μg/kg) and Ochratoxin-A in 100% samples (0.23-2.48 μg/kg); 100% citrinin and 76.09% aflatoxin exceeded Malaysian limits. The presence of mycotoxigenic fungi served as an indicator of mycotoxins contamination and might imply improper production, handling, transportation, and storage of red rice. Further confirmatory analysis (e.g., HPLC) is required to verify the mycotoxins level in red rice samples and to validate the safety status of red rice.

    Along with the sub-urbanisation, people working in urban can stay in the sub-urban areas. Sub-urban housing areas provide cheaper and larger houses and more greenery environment. However, the residents are required to travel in longer distance. The effect on Quality of Life (QOL) due to the migration to sub-urban areas may not be positive even with the better environmental quality and lower direct housing cost. Puncak Alam, a new sub-urban area in Selangor, Malaysia had been chosen as the study area to examine the change of QOL among the residents after they moved into the study area. Through a questionnaire survey, the satisfaction of residents on the various aspects/indicators of QOL were examined. Through the statistical analysis, it is found that slightly more than half of the respondents felt that the QOL was dropped after they were moved to the study area. The sub-urban area did provide better quality for their residents. It had increased respondents’ satisfaction on most of the indicators in the aspects of economic, social and physical. However, due to the decreasing of satisfaction in job opportunities, family life, social activities, safety, and transportation system, most of the respondents were felt that their QOL were dropped.

    Antibiotics are widely prescribed especially for upper respiratory tract infections (URTIs). Their irrational use can increase costs and resistance. Assess knowledge, attitude and prescribing of antibiotics for URTIs in Selangor, Malaysia, using a cross-sectional survey among general practitioners (GPs) working in private clinics in 2011. One hundred and thirty-nine physicians completed the questionnaire (response rate = 34.8%). 49.6% (n = 69) agreed antibiotics are helpful in treating URTIs, with most GPs agreeing antibiotics may reduce URTI duration and complications. The majority of GPs reported they felt patients expected antibiotics, with 36.7% (n = 51) agreeing patients would change doctors if they did not prescribe antibiotics and 21.6% (n = 30) agreeing when requested they prescribe antibiotics even if they believe them to be unnecessary. When assessed against six criteria, most GPs had a moderate level of knowledge of prescribing for URTIs. However, antibiotic prescriptions could be appreciably reduced. Further programs are needed to educate GPs and patients about antibiotics building on current initiatives.

    Soil-transmitted helminthiases are a public health problem in rural communities. A cross-sectional study of the prevalence and distribution of Ascaris lumbricoides, Trichuris trichiura and hookworm was conducted in 281 Orang Asli children (aborigines) aged between 2 and 15 years, from 8 Orang Asli villages in Selangor, Malaysia. All the children were infected with soil-transmitted helminthes, with 26.3% of the children infected either with A. lumbricoides, T. trichiura or hookworm and 72.6% having mixed infection. The overall prevalences of A. lumbricoides, T. trichiura and hookworm were 61.9, 98.2 and 37.0%, respectively. Approximately 19.0, 26.0 and 3.0% of the children had severe infection of ascariasis, trichuriasis and hookworm infection, respectively. The prevalences and mean egg per gram (epg) counts for A. lumbricoides and T. trichiura were not significantly dependent on age, therefore age-dependent convexity was not seen in this study. However, the results of this study reveal an age-dependent prevalence and mean epg count in children with hookworm infection. We conclude that ascariasis, trichuriasis and hookworm infection are still prevalent and therefore a public health concern in Orang Asli communities. Severe ascariasis and trichuriasis may lead to other health and medical problems.

    Rats are considered the principal maintenance hosts of Leptospira. The objectives of this study were isolation and identification of Leptospira serovars circulating among urban rat populations in Kuala Lumpur. Three hundred urban rats (73% Rattus rattus and 27% R. norvegicus) from three different sites were trapped. Twenty cultures were positive for Leptospira using dark-field microscopy. R. rattus was the dominant carrier (70%). Polymerase chain reaction (PCR) confirmed that all isolates were pathogenic Leptospira species. Two Leptospira serogroups, Javanica and Bataviae, were identified using microscopic agglutination test (MAT). Pulsed-field gel electrophoresis (PFGE) identified two serovars in the urban rat populations: L. borgpetersenii serovar Javanica (85%) and L. interrogans serovar Bataviae (15%). We conclude that these two serovars are the major serovars circulating among the urban rat populations in Kuala Lumpur. Despite the low infection rate reported, the high pathogenicity of these serovars raises concern of public health risks caused by rodent transmission of leptospirosis. PMID:23358635

    To determine the associations between socio-demographic characteristics and pubertal status with disordered eating among primary school children. Using a stratified multi-stage sampling, a total of 816 children (282 boys and 534 girls) aged 10 to 11 years from 12 selected primary schools in the state of Selangor, participated in this study. Data were collected on socio-demographic characteristics, pubertal status and disordered eating behaviors. The Pubertal Development Scale and the Children's Eating Attitudes Test (ChEAT) were used to assess pubertal status and disordered eating, respectively. Logistic regression analysis was conducted to determine the risk factors of disordered eating. The prevalence of disordered eating was 30.8% (32.8% in boys and 29.7% in girls). However, the sex difference in the prevalence was not statistically significant. Age, ethnicity and pubertal status were significantly associated with disordered eating in univariate logistic regression analysis. Multivariate logistic regression analysis showed that among boys, being either in an advanced or post-pubertal stage (adjusted OR=8.64) and older age group (adjusted OR=2.03) were risk factors of disordered eating. However, among girls, being a Malay (adjusted OR=3.79) or Indian (adjusted OR=5.04) in an advanced or post-pubertal stage (adjusted OR=2.34) and older age group (adjusted OR=1.53) were risk factors of disordered eating. This study found one in three children had disordered eating. Since ethnicity and pubertal status were identified as risk factors, ethnicity-specific intervention programs on the prevention of disordered eating among children should take into consideration their pubertal status.

    The prevalence of Alzheimer's disease (AD) has increased with the fast growing of aging population, thereby posing great challenges to provision of care for AD patients. Pharmacists play a vital role in the management of AD; this includes recognizing early symptoms of AD, providing medication counseling to AD patients and their caretakers, and identifying potential adverse drug reactions. A comprehensive understanding of the disease progression, as well as the pharmacological therapy, is essential to provide effective care to AD patients. The level of knowledge about AD among the pharmacists, however, remains unknown. Hence, this study aimed to assess the knowledge on AD among the pharmacists in public hospitals and health clinics and its correlates. A clear picture of the characteristics associated with different levels of knowledge could facilitate the targeted re-training of pharmacists. The 30-item validated Alzheimer disease knowledge scale (ADKS) tool was pilot-tested and used in this cross-sectional study. All pharmacists, from nine public hospitals and seven public health clinics in the State of Selangor, Malaysia, were invited to participate in this cross-sectional survey. The ADKS score was computed and compared across demographics characteristics. A total of 445 pharmacists responded to the survey. These pharmacists had a moderate overall score in ADKS; nevertheless, high scores were recorded in the domains of treatment management and care giving. No difference in AD knowledge was found among pharmacists worked in public hospitals and health clinics, except for the domain of care giving ( p = 0.033). Ethnicity and age group were independent predictors of ADKS score in the current study. The pharmacists in the current study had moderate AD knowledge.

    Full Text Available The prevalence of Alzheimer's disease (AD has increased with the fast growing of aging population, thereby posing great challenges to provision of care for AD patients. Pharmacists play a vital role in the management of AD; this includes recognizing early symptoms of AD, providing medication counseling to AD patients and their caretakers, and identifying potential adverse drug reactions. A comprehensive understanding of the disease progression, as well as the pharmacological therapy, is essential to provide effective care to AD patients. The level of knowledge about AD among the pharmacists, however, remains unknown. Hence, this study aimed to assess the knowledge on AD among the pharmacists in public hospitals and health clinics and its correlates. A clear picture of the characteristics associated with different levels of knowledge could facilitate the targeted re-training of pharmacists. The 30-item validated Alzheimer disease knowledge scale (ADKS tool was pilot-tested and used in this cross-sectional study. All pharmacists, from nine public hospitals and seven public health clinics in the State of Selangor, Malaysia, were invited to participate in this cross-sectional survey. The ADKS score was computed and compared across demographics characteristics. A total of 445 pharmacists responded to the survey. These pharmacists had a moderate overall score in ADKS; nevertheless, high scores were recorded in the domains of treatment management and care giving. No difference in AD knowledge was found among pharmacists worked in public hospitals and health clinics, except for the domain of care giving (p = 0.033. Ethnicity and age group were independent predictors of ADKS score in the current study. The pharmacists in the current study had moderate AD knowledge.

    World Health Organization has defined self-medication as the selection and use of medications (including herbal and traditional product) by individuals to treat self-recognized illnesses or symptoms. The prevalence of self-medication is reported to be higher among female students. To investigate the awareness and self-medication practices among female students of higher education institutions in Malaysia. A descriptive, cross-sectional study was conducted in four higher education institutes of Selangor, Malaysia. Convenience sampling approach was used to collect data from a sample 475 students. A "pretested" questionnaire was used as a study instrument. A total of 461 questionnaires were returned (response rate 97.05%). The prevalence of self-medication among female students in higher educational institutions was 57.2% (n = 262). The most common source of self-prescribed medicine was a pharmacy or clinics (n = 206; 45%). It was found that antipyretics were the most common medications used without doctor's consultation (n = 212; 89.1%). Analgesics and antipyretics (n = 79; 62.7%) were highly recommended by students to their family and friends. The common reason for self-medication was prior successful experience (n = 102, 81.0%). The majority of respondents (n = 280; 61.1%) reported that they believed over-the-counter medications were as effective as medications prescribed by a doctor. The prevalence of self-medication practice among female students in the sample of the four higher education institutions was moderate. More studies are required to generalize these findings across Malaysia.

    The Tertiary coal-bearing sequence at Batu Arang in Selangor, Peninsular Malaysia consists of a sandstone-coal-oil shale facies assemblage. A detailed organic petrological and organic geochemical study was carried out on several organic-rich sediments from this sequence. The oil shales are dominated by Botryococcus-derived telalginite and Pediastrum-derived lamalginite. The coals, hypautochthonous in origin, are mainly duroclarite-type, although other minor microlithotypes also occur. Alginite is not observed in the coals, but other liptinitic constituents are very common, particularly thin-walled cutinite and sporinite. The oil shales and the coals are thermally immature. This immaturity has a considerable influence on the biomarker distributions, particularly so on the triterpanes which are dominated by C 31αβ 22R and C 30ββ compounds. Interestingly, for Tertiary aged sediments of continental origin, the diagnostic biomarker compounds such as 18 α(H)-oleanane and bicadinanes, normally linked to the higher land plant group of angiosperms, are not observed in the samples analysed. Tricyclic terpanes occur only in very low relative abundance or are virtually absent. A clear distinction, however, in the biomarker distributions of the shales and the coals/carbargilite can be made based upon the distribution of C 27-C 29 regular steranes: the shales, with a source input being predominantly planktonic algae, are dominated by 5 α(H),14 α(H),17 α(H) 20R cholestane, while the coals/carbargilites, with a source input consisting mainly of higher plant material, are dominated by 5 α(H),14 α(H),17 α(H) 20R ethyl cholestane. The depositional environment of the Batu Arang coal-bearing sequence is interpreted as varying from an alluvial flood plain peat-swamp to fluvio-lacustrine depositional setting.

    There are established differences in cardiovascular disease in different racial groups. Worldwide, the literature regarding the clinical epidemiology of atrial fibrillation in non-white populations is scarce. To document the prevalence of atrial fibrillation (AF) in the multiracial population of Malaysia, and to describe the clinical features and management of these patients. Busy city centre general hospital in Kuala Lumpur, Malaysia, over a 1-month period. One-thousand four hundred and thirty-five acute medical admissions, of whom 40 patients (2.8%) had AF. Of 1435 acute medical admissions to Kuala Lumpur General Hospital over the 4-week study period, 40 had AF (21 male, 19 female; mean age 65 years). Of these, 18 were Malay, 16 Chinese and six Indian. Nineteen patients had previously known AF (seven with paroxysmal AF) and 21 were newly diagnosed cases. The principal associated medical conditions were ischaemic heart disease (42.5%), hypertension (40%) and heart failure (40%). Dyspnoea was the commonest presentation, whilst stroke was the cause of presentation in only two patients. Investigations were under-utilised, with chest X-ray and echocardiography in only 62.5% of patients and thyroid function checked in 15%. Only 16% of those with previously diagnosed AF were on warfarin, with a further three on aspirin. Anticoagulant therapy was started in 13.5% of patients previously not on warfarin, and aspirin in 8%. Records of contraindications to warfarin were unreliable, being identified in only 25%. For those with known AF, 58% were on digoxin. For new onset AF, digoxin was again the most common rate-limiting treatment, initiated in 38%, whilst five patients with new onset AF were commenced on amiodarone. DC cardioversion was not used in any of the patients with new onset AF. Amongst acute medical admissions to a single centre in Malaysia the prevalence of AF was 2.8%. Consistent with previous similar surveys in mainly western (caucasian) populations, standard

    Suicide is one of the ten leading causes of death in the world, accounting for more than 400,000 deaths annually. The pattern of suicide and the incidence of suicide vary from country to country. Cultural, religious and social values play some role in suicide. Compared to the West and some of the countries in the Asian region the incidence of suicide is low in Malaysia. A three-year retrospective study of all the autopsies performed at the University Hospital, Kuala Lumpur was analysed and the cases that were definitely determined as suicides were further studied. 48.8% of all suicides were ethnic Indians though Indians formed only 8% of the Malaysian population. 38.1% of suicides were Chinese who formed 26% of the population while only 3.6% were Malays, who formed 59% of the population. The preferred methods of suicide were poisoning and hanging. The majority were in the age group 20-40 yr. The study may have missed some cases that would have been wrongly concluded as accidental deaths and a few others where the police would have released the bodies without postmortem examinations.

    The aim or this study was to determine factors associated with body weight status among Iranian adolescents in the two Secondary Schools run by the Embassy in Kuala Lumpur. A self administered questionnaire was used to assess socio demographic characteristics, physical activity, and body image. Dietary intake was recorded through individual interviews with the researcher. The Physical Activity Questionnaire for children (PAQ-C) was used to evaluate levels of physical activity of the adolescents. One-third (32.2%) of respondents were of normal weight, 14.5% and 11.1% were overweight and obese respectively, while 18.6% and 23.6% were severe thinness and thinness respectively. While the distribution of obese respondents by gender was almost the same, overweight females (16.4%) exceeded overweight males (12.7%) and although more females were in the thinness category (24.7% compared to 22.7%), more males were severely thin (20.0%) compared to 17.1% of the females. Body weight status was significantly associated with age (p design intervention programs to improve the body weight status of their students.

    Abstract Purpose: Transgender people are frequent targets of discrimination. Discrimination against transgender people in the context of healthcare can lead to poor health outcomes and facilitate the growth of health disparities. This study explores factors associated with medical doctors' intentions to discriminate against transgender people in Malaysia. Methods: A total of 436 physicians at two major university medical centers in Kuala Lumpur, Malaysia, completed an online survey. Sociodemographic characteristics, stigma-related constructs, and intentions to discriminate against transgender people were measured. Bivariate and multivariate linear regression were used to evaluate independent covariates of discrimination intent. Results: Medical doctors who felt more fearful of transgender people and more personal shame associated with transgender people expressed greater intention to discriminate against transgender people, whereas doctors who endorsed the belief that transgender people deserve good care reported lower discrimination intent. Stigma-related constructs accounted for 42% of the variance and 8% was accounted for by sociodemographic characteristics. Conclusions: Constructs associated with transgender stigma play an important role in medical doctors' intentions to discriminate against transgender patients. Development of interventions to improve medical doctors' knowledge about and attitudes toward transgender people are necessary to reduce discriminatory intent in healthcare settings. PMID:29227183

    This study employed contingent valuation method to estimate the willingness to pay (WTP) of the households to improve the waste collection system in Kuala Lumpur, Malaysia. The objective of this study is to evaluate how household WTP changes when recycling and waste separation at source is made mandatory. The methodology consisted of asking people directly about their WTP for an additional waste collection service charge to cover the costs of a new waste management project. The new waste management project consisted of two versions: version A (recycling and waste separation is mandatory) and version B (recycling and waste separation is not mandatory). The households declined their WTP for version A when they were asked to separate the waste at source although all the facilities would be given to them for waste separation. The result of this study indicates that the households were not conscious about the benefits of recycling and waste separation. Concerted efforts should be taken to raise environmental consciousness of the households through education and more publicity regarding waste separation, reducing and recycling.

    Full Text Available The earning and work of fisherman families in Indonesia mostly depend on natural resources using only simple technology. The study was conducted in coastal area of Bontang Kuala, East Kalimantan Province in June and July 2002. One most densely populated sub district was chosen purposively. Result showed that the average income of its family per capita was higher than the average of Indonesian family. Family decision making in economic activities such as fishing investment, catchment’s area selection, technology application were dominated by husband, while in religious, health and domestic activities except child education were dominated by wife. Higher the average contribution of wives to family income the higher the domination of wives in decision making in all activities that commonly dominated by husband. Time allocated for domestic, social, health, and economic activities of wife were higher than that of husband, while for income earning activities husbands’ time was higher that of wives’. Correlation between variables showed that there was significant correlation between public decision making with public division of labor, and level of satisfaction of wives concerning public decision making but not with domestic decision making. Among domestic division of labor there were negative correlation with productive time and with leisure time of wives but not with public division of labor, and husbands’ time allocation.

    Full Text Available Public space takes many spatial forms, including parks, the streets, sidewalks and footpaths that connect an edge of a space between buildings or roadsides, hence are important spaces in an urban setting. In a city context, the public space frames the city image. Kuala Lumpur’s public spaces are typically made up of shopping streets. It allows an ambivalent space that encourages more activities and interactions through the continuity of the street. For that reason, street that brings out life and movement in an urban space is an ideal type of street. In maintaining public spaces and reinventing it, placemaking is a quest for engagement tool to help strengthening legal frameworks in order to protect the public space which is seen viable at a city level. This paper therefore, explores the potentials of public spaces and its management. It applies the case study method by means of investigating two areas in the city encompassing similar characteristics. Generally, the research is designed to test the theoretical framework in managing the public space and its key dimensions in shaping the quality of public space. The researcher then synthesizes the broad range of development of placemaking and the changing uses of public space. The findings will advance further understanding of a suitable application thus intensify the legal framework that shapes the quality of space and its management.

    Full Text Available This study evaluates the feasibility of developing grid-photovoltaic electric boat charging station in Kuala Terengganu using simulation-based method. The main focus is on reducing the dependency on subsidy spent by the government in fisheries sector and encouraging green technology in commercial sector. All data such as solar radiation, amount of subsidy received by fishermen, and fishing activities were collected for the selected area. Economic analyses of the proposed system are discussed based on payback period and net present cost (NPC. The comparison between the proposed system and the grid-only system is done based on the production and consumption of electricity per year, the NPC and emission of pollutant. The system also generates high income from selling energy to the grid with tariff rates RM 1.49/kWh. It is concluded that the proposed system is feasible to be developed in the selected area with the payback period and the NPC are 8.2 years and RM 759,098, respectively. The results also show that the performance of the proposed system is better than grid-only system in all the interested parameters.

    Banks play an essential role in the economic development and banks need to be efficient; otherwise, they may create blockage in the process of development in any country. The efficiency of banks in Malaysia is important and should receive greater attention. This study formulated an appropriate stochastic frontier model to investigate the efficiency of banks which are traded on Kuala Lumpur Stock Exchange (KLSE) market during the period 2005–2009. All data were analyzed to obtain the maximum likelihood method to estimate the parameters of stochastic production. Unlike the earlier studies which use balance sheet and income statements data, this study used market data as the input and output variables. It was observed that banks listed in KLSE exhibited a commendable overall efficiency level of 96.2% during 2005–2009 hence suggesting minimal input waste of 3.8%. Among the banks, the COMS (Cimb Group Holdings) bank is found to be highly efficient with a score of 0.9715 and BIMB (Bimb Holdings) bank is noted to have the lowest efficiency with a score of 0.9582. The results also show that Cobb-Douglas stochastic frontier model with truncated normal distributional assumption is preferable than Translog stochastic frontier model.

    Eighty-six children diagnosed as child abuse and/or neglect were admitted to the Paediatric wards of the General Hospital, Kuala Lumpur during 1985 and 1986. Of these cases, 62 were of physical abuse, six of sexual abuse, one case of both physical and sexual abuse and 17 of neglect. There were 25 boys and 61 girls. Thirty-four of these children were Malays, 16 Chinese, 26 Indians, three mixed and seven illegal immigrants. Twenty-one were below the age of one year, 24 from one to four years, 25 from five to nine years and 16 were ten years and above. The abusers were mainly close members of the family. Of these children, 24 were sent back to their parents and 11 to their relatives home. Twenty-seven were taken into care by the Ministry of Social Welfare and the remaining seven children who were illegal immigrants, were deported with their parents. Only one child was successfully fostered. Eleven children were taken away from the hospital by their parents or guardians without the knowledge of the health staff. There were five deaths in the series.

    The electromagnetic spectrum in the environment is becoming a scarce resource with the emergence of a high number of wireless communications services Cognitive radio (CR) is viewed as a possible solution to the spectrum bottleneck which work in a premise that at an any given time and spatial region there are frequency bands that has no signal occupancy. The CR technique utilizes a temporarily unoccupied licensed band by allowing secondary users to exploit opportunistically the underutilized spectrum licensed to primary users without any harmful interference. Before investigating the technical and political implications of CR, it is necessary to know to what extent the licensed bands are temporally unoccupied. In this paper a spectrum occupancy measurements is conducted to study the utilization of RF spectrum in an environment. The measurements are performed on UHF TV, GSM900 and GSM1800 frequency bands in an urban area in Kuala Lumpur, Malaysia. The evaluation made is based on the power detection principle. From the measurements, the spectrum holes are identified. The obtained results show that the spectral usage is 7.37% for UHF TV band, 12.8% for GSM900 and 5.3% for GSM1800 band leading to the conclusion that a significant amount of spectrum is available for deployment of cognitive radio.

    Motivation has long been associated with sports engagement. However, to date no research has been performed to understand the domain of motivation among ten-pin bowlers. The purpose of this study was to investigate different types of motivation (i.e., intrinsic vs. extrinsic) based on self-determination theory from the perspective of gender and the bowler type (competitive vs. casual). A total of 240 bowlers (104 male, 136 female; 152 competitive, 88 casual) with a mean age of 16.61 ± 0.78 years were recruited in Kuala Lumpur. The Sport Motivation Scale, a 28-item self-report questionnaire measuring seven subscales (i.e., intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, extrinsic motivation to identify regulation, extrinsic motivation for introjection regulation, extrinsic motivation to external regulation, and amotivation) was administered. Results showed significant differences (t=10.43, df=239, p=0.01) between total scores of intrinsic and extrinsic motivation among ten-pin bowlers. There were significant gender differences with respect to intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, and extrinsic motivation to identify regulation. However, no significant bowler type differences were found for either the intrinsic (t=-1.15, df=238, p=0.25) or extrinsic (t=-0.51, df=238, p=0.61) motivation dimensions. In conclusion, our study demonstrated substantial intrinsic motivation for gender effects, but no bowler type effects among adolescent ten-pin bowlers.

    Full Text Available Three residential colleges located in Kuala Lumpur, Malaysia, were selected for energy performance analysis in regards to its implementation of bioclimatic design strategies. Specifically, passive design strategies on daylighting and natural ventilation were examined. In Malaysia, the residential college or hostel is a multi-residential building providing accommodation to university students. The three residential colleges in this study, namely C1, C2 and C3, were built in different years with different designs and forms, particularly with regards to enclosure and facade design, solar control devices, passive daylight concepts, and natural ventilation strategies. The building designs were carefully studied and an electric consumption analysis was carried out in each residential college. This study revealed that the wide-scale implementation of bioclimatic design strategies in college C2 help reduced the annual energy consumption. The building bioclimatic design features that are accountable to reduce energy consumption are the internal courtyard and balconies on each unit of floor area, as shown in C3.Results from this study highly recommend internal courtyard and balcony building combination for multi residential building design, especially in tropical urban regions.

    The solvent-extractable compounds of urban airborne particulate matter were analyzed to determine the distributions of homologous and biomarker tracers. Samples were collected by high-volume air filtration during the haze episode of 1997 around the University of Malaya campus near Petaling Jaya, a suburb of Kuala Lumpur, Malaysia. These results show that the samples contain n-alkanes, n-alkan-2-ones, n-alkanols, methyl n-alkanoates, n-alkyl nitriles, n-alkanals, n-alkanoic acids, levoglucosan, PAHs, and UCM as the dominant components, with minor amounts of terpenoids, glyceryl esters and sterols, all derived from natural biogenic sources (vascular plant wax), from burning of biomass, and from anthropogenic utilization of fossil fuel products (lubricating oil, vehicle emissions, etc.). Some compositional differences are observed in the samples and greater atmospheric concentrations were found for almost all organic components in the samples collected near a roadway. The results interpreted in terms of major sources are due to local build-up of organic contaminants from vehicular emissions, smoke from biomass burning, and natural background as a result of the atmospheric stability during the haze episodes. The organic components transported in from areas outside the region, assuming all smoke components are external to the city, amount to about 30% of the total organic particle burden.

    The role of childcare workers at registered nurseries in supporting exclusive breastfeeding practice is important, as many newborn babies are placed in nurseries during working hours. To increase exclusive breastfeeding rates among working mothers, understanding childcare workers' experiences and needs relating to supporting these mothers is crucial. This study aimed to explore childcare workers' experiences of supporting breastfeeding at registered nurseries. We used a qualitative design to conduct in-depth, semi-structured interviews with ten childcare workers at seven registered nursery centres in Kuala Muda District, Malaysia. Attitudes towards exclusive breastfeeding practice, experiences of breastfeeding training and information, and experiences supporting exclusive breastfeeding at the nursery were explored. Participants were asked to suggest improvements for exclusive breastfeeding practice at their nursery. All interviews were audio recorded, transcribed verbatim, and translated before analysis. All participants demonstrated a positive attitude in supporting and promoting exclusive breastfeeding practice, mainly centred on the advantages of breastfeeding. Various supports have been found such as labelling bottled breastmilk, allowing the mother to come to the nursery during breaks, and providing reading materials. However, several issues emerged that include parents' choice on infant feeding practice, insufficient content on breastfeeding topics during training, and adherence to the (not recommended) practice of bottle feeding expressed breastmilk. Recommendations to enhance breastfeeding were also suggested by participants. Childcare workers may serve as another potential resource for sustaining exclusive breastfeeding at registered nurseries.

    Banks play an essential role in the economic development and banks need to be efficient; otherwise, they may create blockage in the process of development in any country. The efficiency of banks in Malaysia is important and should receive greater attention. This study formulated an appropriate stochastic frontier model to investigate the efficiency of banks which are traded on Kuala Lumpur Stock Exchange (KLSE) market during the period 2005-2009. All data were analyzed to obtain the maximum likelihood method to estimate the parameters of stochastic production. Unlike the earlier studies which use balance sheet and income statements data, this study used market data as the input and output variables. It was observed that banks listed in KLSE exhibited a commendable overall efficiency level of 96.2% during 2005-2009 hence suggesting minimal input waste of 3.8%. Among the banks, the COMS (Cimb Group Holdings) bank is found to be highly efficient with a score of 0.9715 and BIMB (Bimb Holdings) bank is noted to have the lowest efficiency with a score of 0.9582. The results also show that Cobb-Douglas stochastic frontier model with truncated normal distributional assumption is preferable than Translog stochastic frontier model.

    In a cross-sectional study of 7-12 year-old primary school children in Kuala Lumpur city, lung function was assessed by spirometric and peak expiratory flow measurements. Spirometric and peak expiratory flow measurements were successfully performed in 1,214 and 1,414 children, respectively. As expected, the main predictors of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory flow between 25% and 75% of vital capacity (FEF25-75), and peak expiratory flow rate (PEFR) were standing height, weight, age, and sex. In addition, lung function values of Chinese and Malays were generally higher than those of Indians. In multiple regression models which included host and environmental factors, asthma was associated with significant decreases in FEV1, FEF25-75, and PEFR. However, family history of chest illness, history of allergies, low paternal education, and hospitalization during the neonatal period were not independent predictors of lung function. Children sharing rooms with adult smokers had significantly lower levels of FEF25-75. Exposures to wood or kerosene stoves were, but to mosquito repellents were not, associated with decreased lung function.

    To determine the pattern of utilization of emergency department (ED) services by older patients in Kuala Lumpur, Malaysia, compared with younger patients in the same setting. The sociodemographics, clinical characteristics and resource utilization of consecutive patients attending the adult ED at the University Malaya Medical Center were recorded during a typical week. A total of 1649 patients were included in the study; 422/1649 (25.6%) were aged ≥60 years and 1077 (74.4%) were aged Older adult patients were more likely to be diagnosed with ischemic heart disease (12.6% vs 2.5%, P older adults remained an independent predictor of hospital admission (OR 2.75, 95% CI 2.11-3.57). The ratio of older adult patients attending our ED over the proportion of older people in the general population was 26:6, which is far higher than reported in previous published studies carried out in other countries. Older ED attenders are also more likely to require investigations, procedures and hospital admissions. With the rapidly aging population in Malaysia, reconfiguration of resources will need to occur at a compatible rate in order to ensure that the healthcare needs of our older adults are met. © 2014 Japan Geriatrics Society.

    Urbanization is one form of forest modification for development purposes. It produces forest fragments scattered in the landscape with different intensity of disturbance. We want to determine the effect of forest fragmentation towards bird community in urbanized landscapes in Kuala Lumpur, namely Sungai Besi Forest Reserve (FR), Bukit Nenas FR and Bukit Sungei Puteh FR. We used mist-netting and direct observation method along established trails. These forests differ in size, vegetation composition and land use history. Results show that these forests show relatively low number of species compared to other secondary forest with only 39 bird species recorded. The largest fragment, Sg. Besi encompassed the highest species richness and abundance with 69% species but lower in diversity. Bukit Nenas, the next smallest fragment besides being the only remaining primary forest has the highest diversity index with 1.866. Bkt. Sg. Puteh the smallest fragment has the lowest species richness and diversity with Shanon diversity index of 1.332. The presence of introduced species such as Corvus splendens (House crow) in all study areas suggest high disturbance encountered by these forests. Nonetheless, these patches comprised of considerably high proportion of native species. In conclusion, different intensity of disturbance due to logging activities and urbanization surrounding the forest directly influenced bird species richness and diversity. These effects however can be compensated by maintaining habitat complexity including high vegetation composition and habitat structure at the landscape level.

    We aimed to predict the ten-year cardiovascular disease (CVD) risk among low-income urban dwellers of metropolitan Malaysia. Participants were selected from a cross-sectional survey conducted in Kuala Lumpur. To assess the 10-year CVD risk, we employed the Framingham risk scoring (FRS) models. Significant determinants of the ten-year CVD risk were identified using General Linear Model (GLM). Altogether 882 adults (≥30 years old with no CVD history) were randomly selected. The classic FRS model (figures in parentheses are from the modified model) revealed that 20.5% (21.8%) and 38.46% (38.9%) of respondents were at high and moderate risk of CVD. The GLM models identified the importance of education, occupation, and marital status in predicting the future CVD risk. Our study indicated that one out of five low-income urban dwellers has high chance of having CVD within ten years. Health care expenditure, other illness related costs and loss of productivity due to CVD would worsen the current situation of low-income urban population. As such, the public health professionals and policy makers should establish substantial effort to formulate the public health policy and community-based intervention to minimize the upcoming possible high mortality and morbidity due to CVD among the low-income urban dwellers.

    This paper presents a forecasting study of municipal solid waste generation (MSWG) rate and potential of its recyclable components in Kuala Lumpur (KL), the capital city of Malaysia. The generation rates and composition of solid wastes of various classes such as street cleansing, landscape and garden, industrial and constructional, institutional, residential and commercial are analyzed. The past and present trends are studied and extrapolated for the coming years using Microsoft office 2003 Excel spreadsheet assuming a linear behavior. The study shows that increased solid waste generation of KL is alarming. For instance, the amount of daily residential SWG is found to be about 1.62 kg/capita; with the national average at 0.8-0.9 kg/capita and is expected to be increasing linearly, reaching to 2.23 kg/capita by 2024. This figure seems reasonable for an urban developing area like KL city. It is also found that, food (organic) waste is the major recyclable component followed by mix paper and mix plastics. Along with estimated population growth and their business activities, it has been observed that the city is still lacking in terms of efficient waste treatment technology, sufficient fund, public awareness, maintaining the established norms of industrial waste treatment etc. Hence it is recommended that the concerned authority (DBKL) shall view this issue seriously.

    The worksite is one of the key channels for the delivery of interventions to reduce chronic diseases among adult populations. It provides easy and regular access to a relatively stable population and it encourages sustained peer support. This paper reports a 2-year follow-up of the impact of a worksite health promotion programme on serum cholesterol and dietary changes among employees in a city in Malaysia. A quasi-experimental study was conducted among Malay-Muslim male security guards, with those working in a public university in Kuala Lumpur comprising the intervention group, and those working in the teaching hospital of the same university as the comparison group. They were comparable in socio-demographic characteristics. The intervention group received intensive individual and group counselling on diet, physical activity and quitting smoking. The comparison group was given minimal education on the same lifestyle changes through mail and group counselling. The intervention group showed a statistically significant reduction in their mean total cholesterol levels as compared with the comparison group, with an intervention effect of -0.38 (95% CI = -0.63, -0.14) mmol/l. The intervention group also reported a reduction in the amount of cigarettes smoked. The worksite was shown to be an effective channel for health promotion. The adoption of the new lifestyle behaviours should be supported and sustained through modification of work policies.

    Full Text Available This study reviews and analyzes the current practice of zakat distribution in Selangor and the Federal Territory of Malaysia. It is observed that within recent years, zakat distribution in Selangor and the Federal Territory to fi sabilillah recipients constitutes the highest percentage as compared to other groups of recipients. Hence, there is a need to study the relevance of prioritizing fi sabilillah over the other groups of recipients because the more the allocation channeled to a particular group, the more the chances that the rest will eventually have less portion from the zakat. Therefore, the group which is prioritized should have a more significant impact in realizing the goal of zakat. In order to do so, a few aspects must be analysed, including the principle of prioritization or preference in zakat distribution from the Shariah perspective, the definition or interpretation of zakat recipients adopted by these two states and also the zakat allocation method practiced by them. Several recommendations are proposed to improve the zakat distribution in both States.

A study was conducted in Kg. Jenderam Hilir, Sepang. All residents aged 15 years and above from all the 381 households of Kg. Jenderam Hilir were included in this study. A standardized pre-tested structured questionnaire was used in this study. Out of 894 respondents interviewed 69% were males compared to 3.9% of the females (overall 33.6%) reported to have smoked at least once in his/her lifetime. The difference was statistically significant. The mean duration of smoking was 17.7 years. The age at which smoking was first attempted ranged from 4 years to 51 years with a mean of 18.7 years. The mean initiation age for the males was significantly lower as compared to the mean initiation age for the females. The prevalence of current smokers was significantly higher amongst males (52.8%) as compared to the females (1.4%). The prevalence of smoking among current smokers increased with age (p cigarettes smoked by males was significantly higher than the females (p < 0.05). The mean duration of smoking among current smokers was 20 years. There was a significant difference in the level of addiction to smoking and the duration of smoking (p < 0.05). The high level of addiction increased with the duration of smoking (p < 0.05). Sixty five percent of the current smokers reported to have tried to quit smoking while 26% of ever smokers had reported to quit smoking and remained nonsmokers. The quit ratio was calculated to be 26.0%. The quit ratio was 52.6% among those with college or university education. There was a significant difference in the quit ratio by education level (p < 0.01). There was no significant difference in smokers whose parents were smokers as

    Full Text Available Recently, the number of studies involving complex network applications in transportation has increased steadily as scholars from various fields analyze traffic networks. Nonetheless, research on rail network growth is relatively rare. This research examines the evolution of the Public Urban Rail Transit Networks of Kuala Lumpur (PURTNoKL based on complex network theory and covers both the topological structure of the rail system and future trends in network growth. In addition, network performance when facing different attack strategies is also assessed. Three topological network characteristics are considered: connections, clustering and centrality. In PURTNoKL, we found that the total number of nodes and edges exhibit a linear relationship and that the average degree stays within the interval [2.0488, 2.6774] with heavy-tailed distributions. The evolutionary process shows that the cumulative probability distribution (CPD of degree and the average shortest path length show good fit with exponential distribution and normal distribution, respectively. Moreover, PURTNoKL exhibits clear cluster characteristics; most of the nodes have a 2-core value, and the CPDs of the centrality's closeness and betweenness follow a normal distribution function and an exponential distribution, respectively. Finally, we discuss four different types of network growth styles and the line extension process, which reveal that the rail network's growth is likely based on the nodes with the biggest lengths of the shortest path and that network protection should emphasize those nodes with the largest degrees and the highest betweenness values. This research may enhance the networkability of the rail system and better shape the future growth of public rail networks.

    Breast cancer is the most common cancer among women in Malaysia. Of the total cancer cases registered in the National Cancer Registry for 2006, 3,525 were female breast cancer cases. The overall age standardized rate was 39.3 per 100,000 population in 2006. An estimated 30%-40% were diagnosed in the late stages and this had resulted in poor survival rates. The purpose of the study was to determine the factors and barriers related to mammography screening uptake among hospital personnel. This mixed method explanatory study was carried out on a universal sampling of 707 female personnel aged 40 and above, from June 2007 until November 2007. The study was conducted at University Malaya Medical Centre, a tertiary hospital in Kuala Lumpur. Pre-tested self-administered questionnaires were mailed to eligible personnel. The prevalence of mammography screening uptake was 80.3% (95%CI: 76.8%,83.5%) among 534 respondents. Personnel who had physician recommendation had significantly higher odds of mammography screening uptake compared to those who did not have recommendation, adjusted odds ratio of 21.25 (95%CI:12.71,36.56). Reported barriers can be grouped into several themes; negative perception of the procedure like embarrassment due to the presence of male technicians/radiographers; low confidence with radiologist/radiographers in detecting abnormality; lack of coping skills in dealing with expected results and pain during procedure. The findings of this study highlighted that 20% of personnel did not undertake mammography screening although there is no cost incurred and the procedure is fully accessible to them. Opportunistic recommendation by physician and concerns on the procedure should be addressed.

    Lifestyle and disease patterns in Malaysia have changed following rapid economic development. It is important to find out how these changes have affected the nutritional status and health behaviour of the population, especially school children and adolescents. Therefore a survey on school children's and adolescents' health behaviours and perception in Kuala Lumpur was initiated. This paper only reports the observed body mass status of the school children. A total of 3620 school children were selected in this survey using the method of multi-stage sampling. The students were surveyed using pre-tested questionnaires while weight and height were measured by the research team in the field. Using the cut-off of BMI-for-age >or= 95th percentile and <5th percentile for overweight and underweight respectively, there were a total of 7.3% of overweight students and 14.8% of underweight students. When analysed by gender; 7.5% of boys and 7.1% girls were overweight, while 16.2% of the boys and 13.3% of the girls were underweight. The youngest age group (11 years old) had the highest prevalence of underweight as well as overweight. With increasing age, the prevalence of underweight and overweight decreased and more children were in the normal weight range. The overall prevalence of overweight among the three ethnic groups was similar. However the prevalence of underweight was highest among the Indian students (24.9%), followed by Malays (18.9%) and Chinese (9.5%) (P <0.001). The results showed that both the problems of under- and over-nutrition co-exist in the capital city of Malaysia. The promotion of healthy eating and physical activities is required to address the problems of under- and over-nutrition in order to build up a strong and healthy nation in the future.

    The purpose of this retrospective study is to determine the pattern of cerebrospinal fluid (CSF) rhinorrhoea presenting to our tertiary referral centre in Kuala Lumpur and to assess the clinical outcomes of endonasal endoscopic surgery for repair of anterior skull base fistulas. Sixteen patients were treated between 1998 and 2004. The aetiology of the condition was spontaneous in seven and acquired in nine patients. In the acquired category, three patients had accidental trauma and this was iatrogenic in six patients (five post pituitary surgery), with one post endoscopic sinus surgery (ESS). Imaging included computed tomography (CT) scan and magnetic resonance imaging (MRI). Endoscopic repair is less suited for defects in the frontal sinuses with prominent lateral extension and defects greater than 1.5 cm in diameter involving the skull base. Fascia lata, middle turbinate mucosa, nasal perichondrium and ear fat ('bath plug') were the preferred repair materials in the anterior skull base, whereas fascia lata, cartilage and abdominal fat obliteration was preferentially used in the sphenoid leak repair. Intrathecal sodium flourescein helped to confirm the site of CSF fistula in 81.3 per cent of the patients. Ninety per cent of the patients who underwent 'bath plug' repair were successful. The overall success rate for a primary endoscopic procedure was 87.5 per cent, although in two cases a second endoscopic procedure was required for closure. In the majority of cases endoscopic repair was successful, and this avoids many of the complications associated with craniotomy, particularly in a young population. Therefore it is our preferred option, but an alternative procedure should be utilized should this prove necessary.

    Ovitrap surveillance was initiated for eight continuous weeks to determine the distribution and abundance of Aedes sp. mosquitoes in the University of Malaya campus, Kuala Lumpur, and the impact of meteorological conditions on the Aedes populations. Two study areas within the campus were selected: Varsity Lake and Seventh Residential College. The abundance of Aedes populations in Varsity Lake was indicated by ovitrap index (OI) which ranged from 60.00%-90.00%. The mean number of larvae per ovitrap of Aedes albopictus in Varsity Lake ranged from 11.23+/-2.42-43.80+/-6.22. On the other hand, the outdoor OI for Seventh Residential College ranged from 73.33%-93.33%, respectively, while the mean number larvae per ovitrap for this area ranged from 19.33+/-4.55-35.27+/-5.46, respectively. In addition, the indoor OI of Seventh Residential College ranged from 0.00%-30.00%, while the mean number of larvae per ovitrap for Ae. albopictus ranged from 0-5.90+/-3.55. There was no significant difference (p>0.05) of Ae. albopictus population between Varsity Lake and Seventh Residential College. The studies showed a correlation between OI and mean number of larvae per ovitrap for outdoor Ae. albopictus populations in Varsity Lake and Seventh Residential College (r=0.794). There was also a correlation between the mean larvae number per ovitrap of Ae. albopictus obtained from eight weeks indoor ovitrap surveillance in Seventh Residential College with rainfall (r=0.584). However, there was no correlation between the mean larvae number per ovitrap of Ae. albopictus in both study areas with temperature and relative humidity. Aedes aegypti mosquitoes were found neither indoor nor outdoor in both study areas. This study indicated that the principal dengue vector in the university campus was most likely Ae. albopictus.

    Full Text Available Of the four English language skills, speaking enjoys a superior status. Accordingly, it should be given high priority while teaching. In spite of its importance, teaching English speaking skill to Arab EFL learners has always been an exacting task for Arab teachers of English because it is considered a foreign language, i.e. not widely spoken or used in everyday interactions. For such a reason, Arab teachers of English are required to persistently implement new teaching strategies to tackle the problems regarding speaking skills in the classroom. Although a number of studies have been carried out to investigate the difficulties related to teaching English language skills to the Arab students in the Arab World, the current study is regarded the first study which highlights the problems in learning and teaching English speaking skill in the Saudi School in Kuala Lumpur where English is actively spoken as a second language. The main objective of this paper is to investigate the common problems which affect the teaching of English speaking skills to the Arab learners in the Saudi School in Kuala Lumpur. Additionally, it aims at exploring the areas of difficulty that prevent the Arab students from learning to speak in the English classes. This research also scrutinises the role of Kuala Lumpur ESL context on the Arab students’ English language speaking skills. The current study adheres to qualitative method, and its data were collected via classroom observations and face-to-face interviews with four teachers of English and four students selected purposively. Findings included areas like learning and teaching difficulties. The study suggested some techniques to improve the teaching quality and enable the students to overcome their lack of speaking ability such as implementing communicative approach in the English classes.

    Breast cancer is the most common cancer among Malaysian women. This study aimed to determine the reproductive for premenopausal breast cancer risk in Kuala Lumpur, Malaysia. A case-control study was conducted in 216 histopathologically confirmed cases of premenopausal breast cancer and 216 community-based controls that were matched by age within a 5-year period and ethnicity. The results of this study showed that premenopausal breast cancer risks were strongly related to parity, number of live births and family history of breast cancer. Premenopausal women with these known reproductive and family history risk factors should take extra measures to undergo appropriate screening method for early detection of breast cancer.

    Research over the past several decades has indicated that low socioeconomic class has a direct effect on health outcomes. In Malaysia, class distribution may differ with the region. The objective of this study was to compare the presentation and survival of colorectal cancer patients in two dissimilar cities, Kuala Lumpur and Kuching, Sarawak. All patients diagnosed with a malignancy of the colon or rectum in Sarawak General Hospital and University of Malaya Medical Center from 1st Jan 2000-31st Dec 2006 were recruited. Data on presentation, socio-economic class and survival were obtained. The survival duration was categorized into more than three years or three years and less. Testing for significance was performed using the chi-square test, with p values less than 0.05 considered statistically significant. A total of 565 patients in UMMC and 642 patients in SGH had a new diagnosis of colorectal carcinoma. Patients in Kuching had a longer duration of symptoms and more advanced stage at presentation, but this was not statistically significant. Lower socio-economic class was a significant factor for late and more advanced stage at diagnosis, as well as poorer three and five year survival rates. However, survival was lower for patients in Kuching compared to Kuala Lumpur, even after matching for socio-economic class. There is near-zero awareness of colorectal cancer screening in Malaysia. These findings support reaching out to communities of lower socioeconomic backgrounds to improve the colorectal cancer survival rates.

    Full Text Available This paper examines the design quality of People's Housing Project (Program Perumahan Rakyat or PPR low cost high rise flats developed by the National Housing Department (Jabatan Perumahan Negara or JPN in Kuala Lumpur since the 1998. Quality Function Deployment method is used as a tool to analyze the current status and to prioritize the demanded quality from the selected PPR low-cost high rise flats' users. The study revealed that factors in determining a quality low-cost high-rise flat arranged in descending degrees of importance are house safety, provision of public amenities, unit internal environment, maintenance and surrounding environment, location, sanitary fittings, unit size, type of house, material used, unit internal layout, quality of workmanship, structure of the house and appearance. A Quality Chart for PPR low-cost high-rise flats in Kuala Lumpur was presented. Authority (47 per cent has the highest relative degree of importance in determining the quality of PPR flats, followed by Design Element (34 per cent and Quality of Living (19 per cent. Accordingly, the success of the schemes relies strongly on effective control and enforcement by the authorities. However, it can be improved by tackling on the Design Element (Architectural, whereby a revised typical unit layout plan and typical details have been proposed at the last section of the paper.

    The HIV epidemic in Malaysia is concentrated among people who inject drugs (PWID). Accurate estimates of HIV prevalence are critical for developing appropriate treatment and prevention interventions for PWID in Malaysia. In 2010, 461 PWID were recruited using respondent-driven sampling in Greater Kuala Lumpur, Malaysia. Participants completed rapid HIV testing and behavioral assessments. Estimates of HIV prevalence were computed for each of the three recruitment sites and the overall sample. HIV prevalence was 15.8% (95% CI: 12.5-19.2%) overall but varied widely by location: 37.0% (28.6-45.4%) in Kampung Baru, 10.3% (5.0-15.6%) in Kajang, and 6.3% (3.0-9.5%) in Shah Alam. Recruitment extended to locations far from initial interview sites but was concentrated around discrete geographic regions. We document the high prevalence of HIV among PWID in Greater Kuala Lumpur. Sustained support for community surveillance and HIV prevention interventions is needed to stem the HIV epidemic among PWID in Malaysia. PMID:26358544

    Dengue is a serious public health problem in Malaysia. The aim of this study was to compare the vertical infestation of Aedes population in 2 apartments in Kuala Lumpur with different status of dengue incidence (i.e., high-dengue-incidence area and area with no reported dengue cases). The study was also conducted to assess the relationship between environmental factors such as rainfall, temperature, and humidity and Aedes population that may influence Aedes infestation. Surveillance with a mosquito larvae trapping device was conducted for 28 continuous weeks (January to July 2012) in Vista Angkasa (VA) and Inderaloka (IL) apartments located in Kuala Lumpur, Malaysia. The results indicated that both Aedes spp. could be found from ground to higher floor levels of the apartments, with Aedes aegypti being more predominant than Ae. albopictus. Data based on mixed and single breeding of Aedes spp. on different floors did not show any significant difference. Both rainfall (R3; i.e., the amount of rainfall collected during the previous 3 wk before the surveillance period began) and RH data showed significant relationship with the number of Aedes larvae collected in VA and IL. No significant difference was found between the numbers of Aedes larvae in both study areas as well as maximum and minimum temperatures. Results also indicated adaptations of Ae. aegypti to the ecosystem at each elevation of high-rise buildings, with Ae. albopictus staying inside of apartment units.

    Cyrtodactylus metropolis sp. nov. from Batu Caves massif, Selangor, Peninsular Malaysia is differentiated from all congeners by having a unique suite of morphological and color pattern characteristics. Remarkably, this species has been overlooked despite a plethora of field studies at Batu Caves from 1898 to the present and no specimens had ever been examined until now. As with all other limestone forest-adapted Cyrtodactylus in Peninsular Malaysia, C. metropolis sp. nov. is not a cave-adapted species but is far more common on the exterior surfaces of the Batu Caves limestone massif and its surrounding limestone vegetation. We suggest that researchers devote time exploring the exterior surfaces of limestone massifs as well the interiors of their caves.

    The use of preoperative chemoirradiation is the commonest treatment strategy employed in Malaysia for locally advanced rectal cancer. We need to determine the local control and survival rates for comparison with established rates in the literature. This retrospective study analyzed all newly diagnosed patients with rectal adenocarcinoma who underwent long course preoperative radiotherapy (RT) at the Department of Radiotherapy and Oncology, Kuala Lumpur Hospital (HKL) between 1st January 2004 and 31st December 2010. The aim of the study was to determine the radiological response post radiotherapy, pathological response including circumferential resection margin (CRM) status, 3 years local control, 3 years overall survival (OS) and 3 years disease free survival (DFS). Statistical analysis was performed using the SPSS software. Kaplan-Meier and log rank analysis were used to determine survival outcomes. A total of 507 patients with rectal cancer underwent RT at HKL. Sixty seven who underwent long course preoperative RT were eligible for this study. The median age at diagnosis was 60 years old with a range of 26-78 years. The median tumour location was 6 cm from the anal verge. Most patients had suspicion of mesorectum involvement (95.5%) while 28.4% of patients had enlarged pelvic nodes on staging CT scan. All patients underwent preoperative chemo-irradiation except for five who had preoperative RT alone. Only 38 patients underwent definitive surgery (56.7%). Five patients were deemed to be inoperable radiologically and 3 patients were found to have unresectable disease intraoperatively. The remaining 21 patients defaulted surgery (31.3%). The median time from completion of RT to surgery was 8 weeks (range 5.6 to 29.4 weeks). Fifteen patients (39.5%) had surgery more than 8 weeks after completion of RT. Complete pathological response was noted in 4 patients (10.5%). The pathological CRM positive rate after RT was 18.4%. With a median follow-up of 38.8 months, the 3

    Full Text Available Abstract Background With the increasing prevalence of childhood obesity, the metabolic syndrome has been studied among children in many countries but not in Malaysia. Hence, this study aimed to compare metabolic risk factors between overweight/obese and normal weight children and to determine the influence of gender and ethnicity on the metabolic syndrome among school children aged 9-12 years in Kuala Lumpur and its metropolitan suburbs. Methods A case control study was conducted among 402 children, comprising 193 normal-weight and 209 overweight/obese. Weight, height, waist circumference (WC and body composition were measured, and WHO (2007 growth reference was used to categorise children into the two weight groups. Blood pressure (BP was taken, and blood was drawn after an overnight fast to determine fasting blood glucose (FBG and full lipid profile, including triglycerides (TG, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C and total cholesterol (TC.

    The basic function of an international airport is an aerodrome, provides not only the facilities for flights management, but also for customs and passport control. Nowadays, most of the international airports have established commercial outlets for food, products and services. As such, these airports are built with larger scale and more sophisticated on both infrastructure and infostructure which aim to be the most extensive air-travel service providers that connect the nations to the international gateways. Looking at the daily operations of an international airport, the energy consumption is apprehended to be enormous. Besides, knowing the fact that reliance on fossil fuels to power the airport buildings and to run the operations daily, this has led to many negative socioenvironmental implications. To date, some of the world major international airports have begun in renewable energy adoption-which mainly focused on solar energy as a way to reduce fossil energy consumption and towards greenhouse gases reduction. Inspired by thinking differently since solar energy has been adopted in Kuala Lumpur International Airport (KLIA) in 2014, through this study we proposed another form of renewable energy-piezoelectric technology adoption into our KLIA as a feasibility study. We believe that piezoelectric technology could complement the renewable energy mix, by tapping the crowd kinetic energy gathered internally in the airport buildings particularly at a few main entrances. Hence, the objectives of this study are (a) to examine the potential factors that will foster piezoelectric tiles adoption at KLIA and (b) to propose the ways for KLIA in speeding up piezoelectric tiles adoption within the airport terminals. The case study on the Malaysia Airports Holding Berhad (MAHB which manages the KLIA) was based on primary data collected through a series of qualitative focus group conducted on 14 (8 senior managers and 6 technical professionals) who were interested and supportive

    The mass rapid transit (MRT) is the largest transport infrastructure project under the national key economic area (NKEA) in Malaysia. As urban rail is anticipated to be the future spine of public transport network in the Greater Kuala Lumpur city, it is important to mainstream climate change mitigation and public health benefits in the local transport development. This study quantifies the health co-benefits in terms of mortality among the urbanites when the first line of the 150 km MRT system in Kuala Lumpur commences by 2017. Using comparative health risk assessment, we estimated the potential health co-benefits from the establishment of the MRT system. We estimated the reduced CO2 emissions and air pollution (PM2.5) exposure reduction among the general population from the reduced use of motorized vehicles. Mortality avoided from traffic incidents involving motorcycles and passenger cars, and from increased physical activity from walking while using the MRT system was also estimated. A total of 363,130 tonnes of CO2 emissions could be reduced annually from the modal shift from cars and motorcycles to the MRT system. Atmospheric PM2.5 concentration could be reduced 0.61 μg/m3 annually (2%). This could avoid a total of 12 deaths, mostly from cardio-respiratory diseases among the city residents. For traffic injuries, 37 deaths could be avoided annually from motorcycle and passenger cars accidents especially among the younger age categories (aged 15-30). One additional death was attributed to pedestrian walking. The additional daily physical activity to access the MRT system could avoid 21 deaths among its riders. Most of the mortality avoided comes from cardiovascular diseases. Overall, a total of 70 deaths could be avoided annually among both the general population and the MRT users in the city. The implementation of the MRT system in Greater Kuala Lumpur could bring substantial health co-benefits to both the general population and the MRT users mainly from the

    The High Speed Rail Line (HSRL) between Kuala Lumpur (KL) and Singapore (SP) is aimed at reducing to 90 minutes the travel time between two of Southeast Asia’s most vibrant and fast-growing economic engines. Ineco was hired by the Government of Malaysia to forecast the demand for the future HSRL. The Government of Malaysia played a key role when firstly defining the current situation on the corridor and the features of the HSRL, and then providing Ineco with the studies previously developed by them. Besides the obvious interest in connecting both capital cities, Malaysia wishes to promote the economic development of intermediate cities, whereas Singapore, a 718 square-kilometer city-state and island, is interested in improving its connection with Nusajaya - a Malaysian city that is being developed just across the border and regarded as land reserves. Two kinds of services will be provided on the new rail infrastructure: non-stop services between KL and SP, and services with 6 intermediate stops on the Malaysian side. The aim of this paper is to describe the process to forecast the demand for the HSRL Kuala Lumpur – Singapore by focusing on the peculiarities of an international HSRL. Identifying these aspects at an early stage is vital to get a better demand estimate and to reconsider the HSRL characteristics if necessary. The demand for the new line was calculated by applying a three-step model: generation model, distribution model and modal split model. In 2030, 10 years after the opening year, the HSRL is expected to move 23 - 26 million passengers – baseline and optimistic scenarios, respectively -, which represents an 18.5% share of the total demand on the corridor. The demand for the KL-SP pair will account for 30% the demand for the future HSRL. (Author)

    HIV testing services are the gateway into HIV treatment and are critical for monitoring the epidemic. HIV testing is recommended at least annually in high-risk populations, including people who inject drugs (PWID). In Malaysia, the HIV epidemic is concentrated among PWID, but their adherence to testing recommendations and the proportion of HIV-positive PWID who are aware of their status remain unknown. We recruited 460 PWID in Greater Kuala Lumpur using respondent-driven sampling and conducted HIV testing. We examined past testing behaviors, estimating testing frequency, correlates of testing in the past 12 months, and the proportion of those living with HIV who were aware of their status. Results showed that most PWID living with HIV (90.4%, 95% CI: 83.6%-95.9%) were aware of their status. Among those never previously diagnosed with HIV, few had accessed HIV testing in the past 12 months (14.3%, 95% CI: 11.1%-18.0%). Prison (57.0%) and compulsory drug detention centers (36.1%) were the primary locations where PWID reported ever being HIV tested, and the main correlate of recent testing in regression was recent criminal justice involvement. Although awareness of HIV status may be high among PWID living with HIV in Kuala Lumpur, testing occurs primarily in prisons and compulsory drug detention centers, where it is involuntary and linkage to care is limited. A shift in HIV testing policy is needed to align health and human rights objectives, replacing mandatory testing with voluntary testing in settings where individuals can be rapidly linked to HIV care.

    Dengue fever (DF) is a major vector-borne disease in Malaysia. The incidences of DF in Malaysia are caused by viruses transmitted through the bites of infected female Aedes albopictus and Ae. aegypti mosquitoes. This study aims to establish the spatial density of mosquito population or breteau index (BI) in the areas of Kuala Lumpur using geographic information system (GIS), remote sensing (RS) and spatial statistical tools. The 2010 weekly report data of BI obtained from the Ministry of Health (MoH) and the 2010 monthly rainfall data obtained from Malaysia Meteorological Services Department were analyzed using RS and spatial statistical tools to show the spatial correlation of dengue in each zone in Kuala Lumpur. The Kernel density was implemented to identify the better dengue hotspot localities. RESULTS indicated a strong significant positive relationship between the number of localities with high BI and monthly rainfall (r = 0.64; p = 0.024). In addition, types of landuse did not appear to influence the mosquito's population (Built-up: r = 0.16, p = 0.118; Cleared area: r = - 0.107, p = 0.304; Vegetation dense: r = - 0.206, p = 0.046; Vegetation sparse: r = 0.023, p = 0.823; and Water: r = 0.246, p = 0.016).

    6239 children aged 7 to 16 years, attending 22 primary and secondary schools in Kuala Lumpur, Malaysia, were screened using a self report questionnaire, with their heights and weights measured using a digital electronic SECA beam balance. The selection was done by a two staged stratified random sampling from a total of 226 schools in Kuala Lumpur. The racial distribution was 56.7% Malays, 33.8% Chinese and 8.1% Indians; 3.6% (n:222) of the children were identified as obese and 6% (n:373) identified as overweight. The definitions of obese and overweight were computed using growth charts of the National Centre for Health Statistics (NCHS) from the median of the reference population. There were no significant differences amongst the 3 major ethnic groups in the obese group. The differences were significant in the overweight group with the Indians most overweight, followed by the Chinese and the Malays.

    The well established rule for orienting fixed solar devices is to face south for places in the northern hemisphere and northwards for the southern hemisphere. However for regions near the equator such as in Selangor Malaysia, the position of the sun at solar noon is always near zenith both to the north and south depending on location and month of year. This paper reports an analysis of global solar radiation data taken at TNB Solar Research Centre, Malaysia. The solar radiation is measured using both shaded and exposed pyranometers together with a pyrheliometer which is mounted on a sun-tracker. The analysis on the solar measurements show that a near regular solar irradiation pattern had occurred often enough during the year to recommend an optimum azimuth orientation of installing the fixed solar panels tilted facing towards east. Even though all the solar measurements were done at a single location in TNBR Solar Research Centre at Bangi, for locations near the equator with similar weather pattern, the recommended azimuth direction of installing fixed solar panels and collectors tilted eastward will also be generally valid.

    The knowing of geological profile ahead of tunnel face is significant to minimize the risk in tunnel excavation work and cost control in preventative measure. Due to mountainous area, site investigation with vertical boring is not recommended to obtain the geological profile for Pahang-Selangor Raw Water Transfer project. Hence, tunnel seismic prediction (TSP) method is adopted to predict the geological profile ahead of tunnel face. In order to evaluate the TSP results, IBM SPSS Statistic 22 is used to run artificial neural network (ANN) analysis to back calculate the predicted Rock Grade Points (JH) from actual Rock Grade Points (JH) using Vp, Vs and Vp/Vs from TSP. The results show good correlation between predicted Rock Grade points and actual Rock Grade Points (JH). In other words, TSP can provide geological profile prediction ahead of tunnel face significantly while allowing continuously TBM excavation works. Identifying weak zones or faults ahead of tunnel face is crucial for preventative measures to be carried out in advance for a safer tunnel excavation works.

    Full Text Available This paper tries to extent a personal experience on an interesting discussion concerning the communication issues in Medan, North Sumatra. There is the inclination of the North Sumatrans to the news broadcasted by Kuala Lumpur and Medan’s tends to identify with its cultural similarities. For Jakarta is officially the center of political authority over the ‘Indonesian Malay Communities’, this dual cultural loyalty creates an imaginary phenomenon: ‘Two Suns’ in term of authoritative news resources that applies upon ‘One Firmament Culture’. This means that there is a divided news orientation among the Indonesian Malay Communities’ that put Jakarta and Kuala Lumpur in a tacit contestation. While until today this kind of contestation is still going on, the same features have brought me to the phenomenon of hierarchical communication structure. This vividly seen when we realize how lopsided is in nature the communication relations between the global authorities who have controlled the strategic means of communications as well as their contents with the rest of the world. For, in exception to technological matters, the Kuala Lumpurinclined of ‘the Indonesian Malay Communities’ in communication practices is based more on cultural aspects than their technical and political necessities words.

    In Malaysia, homosexuality is illegal; little is known about access to HIV prevention services among Malaysian men who have sex with men (MSM). We analysed PT Foundation outreach data to describe the profiles among MSM who accessed PT Foundation services and to examine factors associated with being aware of PT Foundation and having visited the organization. A survey was administered during weekly outreach throughout Kuala Lumpur from March-December 2012. Pearson's Chi square tests were used to compare demographic and behavioural characteristics of participants who were and were not aware of the PT Foundation. Binary logistic regression was used to identify correlates of MSM visiting the PT Foundation among those who had heard of the organization. Of 614 MSM, this study found significantly higher awareness of the PT Foundation among MSM who perceived they had "good" HIV knowledge (p = .026) and participants who reported always using condoms (p = .009). MSM who reported being paid for sex were 2.81 times as likely to visit the PT Foundation compared to men who did not. A subgroup of MSM known to be at high risk for HIV infection is accessing prevention services. Future studies should uncover motivations and barriers of accessing these services among MSM in Malaysia. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Loss of appetite, decrease in food intake and changes in body composition appear to be inter-related factors that can influence the well-being of older individuals. Therefore, a study was conducted to determine the level of appetite, food intake and its relation to body composition and functional status among noninstitutionalised elderly Malays in Cheras, Kuala Lumpur. The Council on Nutrition Appetite Questionnaire (CNAQ), Diet History Questionnaire (DHQ), Bio-impedance Analysis (BIA) and Instrumental Activity of Daily Living (IADL) questionnaire and handgrip dynamometer were used to measure appetite, food intake, body composition and functional status respectively. A total of 112 subjects (41.1% men and 58.9% women) participated with mean age being 66.0 ± 5.0 years for men and 66.3 ± 6.2 years for women. Prevalence of poor appetite was higher in elderly women (72.3%) than in men (52.3%) (page (r=-0.255, page, low energy intake and decreased functional status. In conclusion, the study showed that poor appetite was prevalent among the subjects, especially women and this was influenced by aging, inadequate energy intake and decreased functional status.

    Osteoporosis is a significant health problem in the developing countries and its prevalence data are important for the estimation of health care burden and policy making. This study aimed to determine the age-related changes in bone health and the prevalence of osteoporosis in males and females aged 50 years or above living in Kuala Lumpur, Malaysia. A cross-sectional study was conducted between December 2014 and December 2015. Subjects answered a demographic questionnaire and underwent body anthropometric and bone health measurement. Assessment of bone health was performed using a quantitative ultrasound device that generated speed of sound, broadband ultrasound attenuation, stiffness index, and T-score based on stiffness index value as bone health indices. The prevalence of osteoporosis was 10.6% in males and 8.0% in females. Significant age-related decline of bone health indices (speed of sound, broadband ultrasound attenuation, stiffness index, and T-score) and a concurrent increase in the prevalence of osteoporosis and osteopenia were observed in females (P0.05). Ethnic differences in bone health indices and prevalence of osteoporosis/osteopenia were not observed (P>0.05). A significant proportion of males and females age 50 years or above have suboptimal bone health. Preventive measures such as early screening should be implemented to retard the progression of osteoporosis.

    The prevalence of asthma is increasing, especially among children in Malaysia, with environmental factors as one of the main preventable contributors. The aim of this study was to determine the association between environmental air pollutants and the occurrence of asthma among children seen in pediatric clinics in Universiti Kebangsaan Malaysia Medical Center (UKMMC), Kuala Lumpur. An unmatched case control study among children who attended the pediatric clinic was carried out from May to August 2015. A total of 223 children who were diagnosed with asthma (105 cases) and who did not have asthma (118 controls) were included in this study. Their parents or caregivers were interviewed using questionnaires modified from the International Study of Asthma and Allergies in Childhood. Data obtained were analyzed using SPSS software version 20. There was a higher risk of asthma in those who had carpet at home (OR = 2.15 CI [1.25-3.68]), those who lived within 200 m of heavy traffic (OR = 1.72 CI [1.01-2.93]), and those who were exposed to lorry fumes (OR = 2.61. CI [1.38-4.93]). Environmental air pollutants increased the risk of asthma among children in Malaysia. Exposure to congested roads, lorry fumes, and indoor carpet were associated with asthma among children in this study. Parents or caretakers of children with asthma should be given adequate education on the prevention of asthmatic attack among these children. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Sinkhole is not classified as new phenomenon in this country, especially surround Klang Valley. Since 1968, the increasing numbers of sinkhole incident have been reported in Kuala Lumpur and the vicinity areas. As the results, it poses a serious threat for human lives, assets and structure especially in the capital city of Malaysia. Therefore, a Sinkhole Hazard Model (SHM) was generated with integration of GIS framework by applying Analytical Hierarchical Process (AHP) technique in order to produced sinkhole susceptibility hazard map for the particular area. Five consecutive parameters for main criteria each categorized by five sub classes were selected for this research which is Lithology (LT), Groundwater Level Decline (WLD), Soil Type (ST), Land Use (LU) and Proximity to Groundwater Wells (PG). A set of relative weights were assigned to each inducing factor and computed through pairwise comparison matrix derived from expert judgment. Lithology and Groundwater Level Decline has been identified gives the highest impact to the sinkhole development. A sinkhole susceptibility hazard zones was classified into five prone areas namely very low, low, moderate, high and very high hazard. The results obtained were validated with thirty three (33) previous sinkhole inventory data. This evaluation shows that the model indicates 64 % and 21 % of the sinkhole events fall within high and very high hazard zones respectively. Based on this outcome, it clearly represents that AHP approach is useful to predict natural disaster such as sinkhole hazard.

    A cross-sectional study was carried out to assess the physical activity levels among patients with type 2 diabetes mellitus (DM) at Cheras Health Clinic in Kuala Lumpur. A total of 132 subjects (62 men and 70 women) aged 30 years and above participated in this study. Data was collected using an interview based questionnaire to obtain socio-demographic and health profile information. Physical activity was assessed using a shortened version of the International Physical Activity Questionnaire (IPAQ). Anthropometric measurements and body fat were also taken. Glycaemic status, that is, HbA1c, fasting blood sugar (FBS) and 2 hours post-prandial (2-HPP) were obtained from medical records. Results showed that the mean age of the patients was 51.9 + 5.8 years. The majority of patients had poor glycaemic control based on HbA1c (70.7%), FBS (71.9%) and 2HPP (85.4%). Patients who were unmarried and aged(60 years and above had a lower physical activity level (p< 0.05). In the older age group, low physical activity was associated with poor glycaemic control (p< 0.05). Patients in the moderate and high physical activity level were motivated to perform physical activity so as to be healthy (68.1%). Low physical activity level among patients was due to lack of time (54.5%) and lack of energy (21.2%). In conclusion, physical activity levels of the patients were unsatisfactory and associated with poor glycaemic control, especially in the elderly. There is a need to encourage diabetic patients to undertake regular physical activity in order to achieve optimal glycaemic control.

    Cisgender and transgender woman sex workers (CWSWs and TWSWs, respectively) are key populations in Malaysia with higher HIV-prevalence than that of the general population. Given the impact economic instability can have on HIV transmission in these populations, novel HIV prevention interventions that reduce poverty may reduce HIV incidence and improve linkage and retention to care for those already living with HIV. We examine the feasibility of a microfinance-based HIV prevention intervention among CWSW and TWSWs in Greater Kuala Lumpur, Malaysia. We conducted 35 in-depth interviews to examine the acceptability of a microfinance-based HIV prevention intervention, focusing on: (1) participants' readiness to engage in other occupations and the types of jobs in which they were interested in; (2) their level of interest in the components of the potential intervention, including training on financial literacy and vocational education; and (3) possible barriers and facilitators to the successful completion of the intervention. Using grounded theory as a framework of analysis, transcripts were analysed through Nvivo 11. Participants were on average 41 years old, slightly less than half (48%) were married, and more than half (52%) identified as Muslim. Participants express high motivation to seek employment in other professions as they perceived sex work as not a "proper job" with opportunities for career growth but rather as a short-term option offering an unstable form of income. Participants wanted to develop their own small enterprise. Most participants expressed a high level of interest in microfinance intervention and training to enable them to enter a new profession. Possible barriers to intervention participation included time, stigma, and a lack of resources.

Results showed that the concentration of Pb in indoor air was in the range of 5.18 ± 1.08 μg/g–7.01 ± 0.08 μg/g. All the concentrations of Pb in indoor air were higher than in outdoor air at all sampling stations. The concentrations of cations and anions were higher in outdoor air than in indoor air. The concentration of Ca2+ (39.51 ± 5.01 mg/g–65.13 ± 9.42 mg/g) was the highest because the cation existed naturally in soil dusts, while the concentrations of NO3 − and SO4 2− were higher in outdoor air because there were more sources of exposure for anions in outdoor air, such as highly congested traffic and motor vehicles emissions. In comparison, the concentration of NO3 − (29.72 ± 0.31 μg/g–32.00 ± 0.75 μg/g) was slightly higher than SO4 2−. The concentrations of most of the parameters in this study, such as Mg2+, Ca2+, NO3 −, SO4 2−, and Pb2+, were higher in outdoor air than in indoor air at all sampling stations. PMID:25136371

    With the rising trend of obesity among the general population, it is also important to assess the obesity and health status among military population. The aim of this study was to determine the prevalence of overweight and obesity among Malaysian Army (MA) personnel as well as the relationship between selected socio-demographics factors, antropometric profiles, body composition and random blood test value. A cross sectional study involving 378 male military personnel aged between 20 to 48 years old was conducted at two MA bases in Kuala Lumpur between November and December 2012. Antropometric measurements included height, weight and waist circumference (WC). Body fat percentage was measured using bioelectrical impedance analysis method (Tanita TBF-300A). Mean height, weight, BMI, WC, body fat percentage, age, monthly income and duration of service were 1.71 ± 0.6 m, 71.7 ± 12.2 kg, 24.6 ± 4.1 kg/m2, 87.0 ± 10.0 cm, 23.4 ± 6.6%, 29.1 ± 5.5 years, RM 2115.12 ± 860.70 and 9.9 ± 5.6 years respectively. According to WHO (1998) classification of BMI, 3.2% of the subjects were underweight, 54.8% normal, 32.8% overweight and 9.3% obese. It was obeserved that 40.2% of the subjects had waist circumference value of 90 cm or more and were considered high risk for diebetes and cardiovascular diseases. This study found that BMI was highly correlated with weight (r=0.925, ppopulation. Therefore, future intervention from the aspect of nutritional education and health awareness can benefit thus optimizing the health status of MA military personnel.

    Plasmodium knowlesi, a malaria parasite of macaques, has emerged as an important parasite of humans. Despite the significance of P. knowlesi malaria in parts of Southeast Asia, very little is known about the genetic variation in this parasite. Our aim here was to explore sequence variation in a molecule called the 42kDa merozoite surface protein-1 (MSP-1), which is found on the surface of blood stages of Plasmodium spp. and plays a key role in erythrocyte invasion. Several studies of P. falciparum have reported that the C-terminus (a 42kDa fragment) of merozoite surface protein-1 (MSP-1 42 ; consisting of MSP-1 19 and MSP-1 33 ) is a potential candidate for a malaria vaccine. However, to date, no study has yet investigated the sequence diversity of the gene encoding P. knowlesi MSP-1 42 (comprising Pk-msp-1 19 and Pk-msp-1 33 ) among isolates in Malaysia. The present study explored this aspect. Twelve P. knowlesi isolates were collected from patients from hospitals in Selangor and Sabah Borneo, Malaysia, between 2012 and 2014. The Pk-msp-1 42 gene was amplified by PCR and directly sequenced. Haplotype diversity (Hd) and nucleotide diversity (л) were studied among the isolates. There was relatively high genetic variation among P. knowlesi isolates; overall Hd and л were 1±0.034 and 0.01132±0.00124, respectively. A total of nine different haplotypes related to amino acid alterations at 13 positions, and the Pk-MSP-1 19 sequence was found to be more conserved than Pk-msp-1 33 . We have found evidence for negative selection in Pk-msp- 42 as well as the 33kDa and 19kDa fragments by comparing the rate of non-synonymous versus synonymous substitutions. Future investigations should study large numbers of samples from disparate geographical locations to critically assess whether this molecule might be a potential vaccine target for P. knowlesi.

    Mental disorders are a major public health problem and are debilitating in many nations throughout the world. Many individuals either do not or are not able to access treatment. The Internet can be a medium to convey to the community accessible evidenced-based interventions to reduce these burdens. The objective of this study is to investigate the effectiveness of 4 weeks of a Web-based psychoeducational intervention program for depressive and anxiety symptoms in the community of Selangor, Malaysia. A two-arm randomized controlled trial of a single-blind study will be conducted to meet the objective of this study. We aim to recruit 84 participants each for the intervention and control groups. The recruitment will be from participants who participated in the first phase of this research. The primary outcomes of this study are depressive and anxiety scores, which will be assessed using the Patient Health Questionnaire 9 and Generalized Anxiety Disorder 7, respectively. The secondary outcome includes mental health literacy of the participants, which will be assessed using the self-developed and adapted Mental Health Literacy Questionnaire. The psychoeducational intervention program consists of four sessions, which will be accessed each week. The depressive and anxiety symptoms will be compared between participants who participated in the psychoeducational program compared with the control group. Depressive and anxiety scores and mental health literacy will be assessed at week 1 and at follow-ups at week 5 and week 12, respectively. The psychoeducational intervention program consists of four sessions, which will be accessed at each week. The depressive and anxiety symptoms will be compared between the intervention and control groups using a series of mixed ANOVAs. Depressive and anxiety scores and mental health literacy will be assessed at week 1 and at two follow-ups at week 5 and week 12, respectively. To our knowledge, this study will be the first randomized

    This research aimed to determine HIV prevalence, risk behaviour and knowledge of transmission methods among men who have sex with men (MSM) in Kuala Lumpur, Malaysia. Venue-day-time sampling (VDTS) was applied to identify venues where men congregate to solicit sex from other men. Participants recruited from clubs, massage parlours, saunas and one park self-completed a computerized behavioural questionnaire, were administered an oral rapid HIV test and given the opportunity to return later to receive full counselling and learn their HIV status. A total of 517 men were enrolled into the study. The majority were Malays (47.0%) and Chinese (43.7%). Twenty tested HIV positive (3.9%). Significant predictors of HIV infection included having unprotected anal sex with a casual partner (44.9% of participants, odds ratio [OR] = 2.99; 95% confidence interval [CI] 1.13-7.90; P = 0.027), having unprotected receptive anal sex (27.9%, OR = 2.71; 95% CI 1.10-6.54; P = 0.030) and having group sex (33.3%, OR = 3.95; 95% CI 1.55-10.09; P = 0.004). One in five participants (20.1% and 19.5%) did not believe that HIV could be transmitted through insertive or receptive anal sex, respectively. Risk behaviour is high and knowledge of HIV transmission methods was low among MSM in Kuala Lumpur. Future prevention efforts should focus on providing risk reduction education to this community.

    Vitamin D status, as indicated by 25-hydroxyvitamin D is inversely associated with adiposity, glucose homeostasis, lipid profiles, and blood pressure along with its classic role in calcium homeostasis and bone metabolism. It is also shown to be inversely associated with metabolic syndrome and cardiovascular diseases in western populations. However, evidence from the Asian population is limited. Therefore, we aim to study the prevalence of vitamin D insufficiency (Kuala Lumpur. This is an analytical cross sectional study. A total of 380 subjects were sampled and their vitamins D status (25-hydroxyvitamin D), fasting blood glucose, full lipid profile were assessed using venous blood. Systolic and diastolic blood pressure, weight, height and waist circumference were measured following standard protocols. Socio-demographic data such as sex, age, smoking status etc were also collected. Data was analysed using t-test, chi-square test, General Linear Model and multiple logistic regression. Females made up 58% of the sample. The mean age of respondents was 48.5 (SD 5.2) years. Females had significantly lower mean Vitamin D levels (36.2; 95% CI: 34.5, 38.0 nmol/L) compared to males (56.2; 95% CI: 53.2, 59.2 nmol/L). Approximately 41% and 87% of males and females respectively had insufficient (Kuala Lumpur. Vitamin D insufficiency is independently associated with younger age, female sex and greater abdominal obesity. Vitamin D insufficiency is also associated with Metabolic Syndrome.

    There is sufficient evidence to conclude that tobacco smoking is strongly linked to tuberculosis (TB) and a large proportion of TB patients may be active smokers. In addition, a previous analysis has suggested that a considerable proportion of the global burden of TB may be attributable to smoking. However, there is paucity of information on the prevalence of tobacco smoking among TB patients in Malaysia. Moreover, the tobacco-related knowledge, attitudes, and behaviors of TB patients who are smokers have not been previously explored. This study aimed to document the prevalence of smoking among newly diagnosed TB patients and to learn about the tobacco use knowledge and attitudes of those who are smokers among this population. Data were generated on prevalence rates of smoking among newly diagnosed TB patients in the State of Penang from January 2008 to December 2008. The data were obtained based on a review of routinely collated data from the quarterly report on TB case registration. The study setting comprised of five healthcare facilities (TB clinics) located within Penang and Wilayah Persekutuan, Kuala Lumpur health districts in Malaysia, which were involved in a larger project, known as SCIDOTS Project. A 58-item questionnaire was used to assess the tobacco use knowledge, attitudes and behaviors of those TB patients who were smokers. Smoking status was determinant in 817 of 943 new cases of TB from January to December 2008. Of this, it was estimated that the prevalence rates of current- and ex-smoking among the TB patients were 40.27% (329/817) and 13.95% (114/817), respectively. The prevalence of ever-smoking among patients with TB was estimated to be 54,220 per 100,000 population. Of 120 eligible participants for the SCIDOTS Project, 88 responded to the survey (73.3% response rate) and 80 surveys were analyzed (66.7% usable rate). The mean (+/- SD) total score of tobacco use knowledge items was 4.23 +/- 2.66 (maximum possible score=11). More than half of the

    Surgical site infection (SSI) after craniotomy even though rare, poses a real risk of surgery and represents a substantial burden of disease for both patients and healthcare services in terms of morbidity, mortality and economic cost. The knowledge of risk factor for surgical site infection after craniotomy will allow the authority to implement specific preventive measures to reduce the infection rate. Therefore, the objectives of this study are to determine the incidence and the risk factors of surgical site infection after craniotomy. This study highlights an observational prospective study on adult patients who has undergone neurosurgical procedures in Hospital Kuala Lumpur (HKL) over a period of 2 years (June 2007 to June 2009). The neurosurgical procedures are craniectomy, craniotomy, cranioplasty and burrhole. A total of 390 cases fulfilled the requirements of inclusion and exclusion criteria were included in the study. Every patient in the study population was prospectively evaluated for development and risk factors for SSI. The follow-up cases were done by direct observation of the wound during their post-operative stay and ideally up to and including day 30 post-operatively, either as in-patients or through post discharge surveillance i.e. follow-up in the clinic 30 days post-operatively. SSIs were defined according to the Center for Disease Control definitions. Incidence was calculated per patient. Univariate Simple Logistic Regression analysis was used to analyse the association of the risk factors and SSI. A total of 30 post craniotomy surgical site infections (SSI) has been identified among 390 cases included in the study, resulting in an overall infection rate of 7.7%. This included 19 with superficial wound infection (63.3%), 9 with bone flap osteitis (30%) and 2 with organ/space infection (6.7%). Most of SSIs were detected during in patient cases accounting for 20 cases. The mean time between surgery and the onset of infection was 11.8 +/- 21.8 days

    Full Text Available Forward from the sustainability agenda of Brundtland in 1987 and the increasing demand for energy efficient buildings, the building industry has taken steps in meeting the challenge of reducing its environmental impact. Initiatives such as ‘green’ or ‘sustainable’ design have been at the forefront of architecture, while green assessment tools have been used to predict the energy performance of building during its operational phase. However, there is still a significant hap between predicted or simulated energy measurements compared to actual operational energy consumption, or is more commonly referred as the ‘performance gap’. This paper tries to bridge this gap by comparing measured operational energy consumption of a Green Building Index (GBI certified office building in Kuala Lumpur, with its predicted energy rating qualification.

    Cement is the primary material used in solidifying the soft soils. This material was applied in solidifying Kuala Perlis dredged marine sediments (DMS). These unwanted sediments are classified as high plasticity silt, MH with 3.36 LL of wc/LL value. At dosage 10 and 20 % of cemented-DMS and 3 days curing time, compression curve results shows the settlement criteria were enhanced than the natural DMS. Unfortunately, the settlement criteria are not complies with the permissible settlement limit and applicable pressure. The formation of cementing compounds appears in the SEM micrograph for 10 and 20 % of cemented-DMS. EDX analysis shows the Ca:Si ratio were increased for cemented-DMS due to the formation of C-S-H gel.

    We investigated 12 X-chromosomal short tandem repeat (STR) polymorphisms in 283 unrelated Malay individuals (160 males and 123 females) living in and around Kuala Lumpur using the Investigator Argus X-12 kit. Heterozygosity among the present 12 X-STRs showed a distribution of from 55.3 to 93.5 %. The diversity values of the haplotypes constructed using four closely linked groups were all higher than 0.9865. A comparison of allelic frequency in each system and haplotype variation indicated that the nature of these X-STRs in the Malay population differed from that in East Asian, European, or African populations. Several microvariant alleles found in the Malay population were characterized and compared with known sequence data. The present data may be helpful in forensic casework such as personal identification and kinship testing in the Malay population in Malaysia.

    Deficiencies of micronutrients can affect the growth and development of children. There is increasing evidence of vitamin D deficiency world-wide resulting in nutritional rickets in children and osteoporosis in adulthood. Data on the micronutrient status of children in Malaysia is limited. The aim of this study was to determine the anthropometric and micronutrient status of primary school children in the capital city of Kuala Lumpur. A cross sectional study of primary aged school children was undertaken in 2008. A total of 402 boys and girls aged 7-12 years, attending primary schools in Kuala Lumpur participated in the study. Fasting blood samples were taken to assess vitamin D [as 25(OH)D], vitamin B12, folate, zinc, iron, and ferritin and haemoglobin concentrations. Height-for-age and body mass index for age (BMI-for-age) of the children were computed. Most of the children had normal height-for-age (96.5%) while slightly over half (58.0%) had normal BMI-for-age. A total of 17.9% were overweight and 16.4% obese. Prevalence of obesity was significantly higher among the boys (25%) than in the girls (9.5%) (χ2 = 22.949; P 37.5-≤ 50 nmol/L). Among the boys, a significant inverse association was found between serum vitamin D status and BMI-for-age (χ2 = 5.958; P = .016). This study highlights the presence of a high prevalence of sub-optimal vitamin D status among urban primary school children in a tropical country. In light of the growing problem of obesity in Malaysian children, these findings emphasize the important need for appropriate interventions to address both problems of obesity and poor vitamin D status in children.

    There is a rapid increase in the population of the elderly globally, and Malaysia is anticipated to become an ageing nation in 2030. Maintaining health, social participation, reducing institutionalization, and improving quality of life of the elderly are public health challenges of the 21(st) century. Quality of life among elderly in Elderly Homes in Malaysia is under researched. This study aims to determine the quality of life and its associated factors among the Elderly in Elderly Homes in Kuala Lumpur. This was a cross-sectional study among 203 residents aged 60 years or more in eight randomly selected Elderly Homes in Kuala Lumpur in September 2014. Stratified simple random sampling was used to select participants. Study instruments included World Health Organization Quality of Life Questionnaire-Brief Version (WHOQOL-BREF), Multidimensional Scale for Perceived Social Support, and a questionnaire for Socio-demographic variables. Data collection was by face to face interview. Univariate and Multivariate analysis were used to determine associations, and P-value age, gender, level of education, economic status, outdoor leisure activity, physical activity, duration of residence, type of accommodation, co-morbidities, and social support. This study confirms that multiple factors are associated with quality of life among elderly in elderly homes. Social support, chronic co-morbidities, gender and outdoor leisure activity were significantly associated with all the domains of quality of life. Among the four domains of quality of life, the physical domain had the highest score while the social domain had the lowest score. This emphasizes the need for more social support-related interventions in these homes.

    Full Text Available Objective: Maternal factors such as age, health, diet, and environment are significantly associated with low birth weight. The objectives of this study were to determine the incidence, distribution and major risk factors of low birth weight in Hospital Kuala Lumpur.Materials and methods: A hospital based case–control study was done in Obstetric Ward of Maternity Hospital in Hospital Kuala Lumpur. Data was obtained using questionnaire and Performa. Out of 1021 deliveries, 330 were selected randomly as respondents that comprises of 110 cases and 220 controls. The outcome measure was low birth weight (<2500 grams.Results: The incidence of low birth weight was 10.8%. Among races, the highest occurrence of low birth weight was in Malay, while the highest age group was between 21 years old to 34 years old with majority of the respondent were married. Among the maternal socio-demographic factors, maternal height of less than 150 cm has a significant relationship with low birth weight. In addition, maternal weight of 45 kg and less and maternal weight gain during pregnancy of less than 10 kg were also found to be risk factors. However, none of the socio-demographic factors were significantly associated with low birth weight deliveries. Similarly, signs of premature delivery, maternal vaginal bleeding and fetal growth retardation (IUGR had a significant association.Conclusion: The mothers that have experienced any of the risks that were identified should be monitored and effective prevention should be taken to decrease the chances of low birth weight but not forgetting to promote a health lifestyle to the mother and father as well.

    HIV-1 epidemics among men who have sex with men (MSM) continue to expand in developed and developing countries. Although HIV infection in MSM is amongst the highest of the key affected populations in many countries in Southeast Asia, comprehensive molecular epidemiological study of HIV-1 among MSM remains inadequate in the region including in Malaysia. Here, we reported the phylodynamic profiles of HIV-1 genotypes circulating among MSM population in Kuala Lumpur, Malaysia. A total of n = 459 newly-diagnosed treatment-naïve consenting subjects were recruited between March 2006 and August 2012, of whom 87 (18.9%) were self-reported MSM. Transmitted drug resistance mutations were absent in these isolates. Cumulatively, phylogenetic reconstructions of the pro-rt gene (HXB2∶2253-3275) showed that HIV-1 subtype B and CRF01_AE were predominant and contributed to approximately 80% of the total HIV-1 infection among MSM. In addition to numerous unique transmission lineages within these genotypes, twelve monophyletic transmission clusters of different sizes (2-7 MSM sequences, supported by posterior probability value of 1) were identified in Malaysia. Bayesian coalescent analysis estimated that the divergence times for these clusters were mainly dated between 1995 and 2005 with four major transmission clusters radiating at least 12 years ago suggesting that active spread of multiple sub-epidemic clusters occurred during this period. The changes in effective population size of subtype B showed an exponential growth within 5 years between 1988 and 1993, while CRF01_AE lineage exhibited similar expansion between 1993 and 2003. Our study provides the first insight of the phylodynamic profile of HIV-1 subtype B and CRF01_AE circulating among MSM population in Kuala Lumpur, Malaysia, unravelling the importance of understanding transmission behaviours as well as evolutionary history of HIV-1 in assessing the risk of outbreak or epidemic expansion.

    Intracranial arteriovenous malformations (AVMs) of Spetzler-Martin grades (SMGs) I-III are treated using either monomodality treatments of microsurgical excision, embolization or stereotactic radiosurgery (SRS), or a combination of two or more of these treatment options. At Hospital Kuala Lumpur, we still practice monomodality treatments for AVMs of these three grades. In this study, we wanted to achieve an understanding whether monomodality treatments can achieve a satisfactory outcome of AVM nidi for patients, for up to 3 years, and to gather an objective data for AVM treatment for the Malaysian population. This is a retrospective review of records study. The data are acquired from case notes of patients with intracranial AVM of SMGs I to III who underwent monomodality treatment at Hospital Kuala Lumpur between 2008 and 2011. The patients were followed up with imaging for up to 3 years from the date of treatment. A total of 81 patients were recruited in this study, where 30 underwent microsurgical treatment, 27 underwent embolization, and 24 underwent SRS. Total obliteration of AVM nidus was achieved in 96.7% of patients who underwent microsurgery, 8.7% of patients who underwent embolization, and 79.2% of patients who underwent SRS. The modified Rankin scale (mRS) for all three groups showed an improving trend, with the microsurgery group showing the best improvement (from 70% at 3 months to 92.3% at 3 years showing favorable mRS scores). The AVM nidus obliteration for each treatment group is comparable to the meta-analysis published in 2011. Each modality had its own set of complications; however, most of the patients in all three groups had either static or improved mRS at the end of the 3-year follow-up.

    Full Text Available Abstract Background Deficiencies of micronutrients can affect the growth and development of children. There is increasing evidence of vitamin D deficiency world-wide resulting in nutritional rickets in children and osteoporosis in adulthood. Data on the micronutrient status of children in Malaysia is limited. The aim of this study was to determine the anthropometric and micronutrient status of primary school children in the capital city of Kuala Lumpur. Methods A cross sectional study of primary aged school children was undertaken in 2008. A total of 402 boys and girls aged 7-12 years, attending primary schools in Kuala Lumpur participated in the study. Fasting blood samples were taken to assess vitamin D [as 25(OHD], vitamin B12, folate, zinc, iron, and ferritin and haemoglobin concentrations. Height-for-age and body mass index for age (BMI-for-age of the children were computed. Results Most of the children had normal height-for-age (96.5% while slightly over half (58.0% had normal BMI-for-age. A total of 17.9% were overweight and 16.4% obese. Prevalence of obesity was significantly higher among the boys (25% than in the girls (9.5% (χ2 = 22.949; P 12. In contrast, 35.3% of the children had serum 25(OHD concentrations indicative of vitamin D deficiency(≤37.5 nmol/L and a further 37.1% had insufficiency concentrations (> 37.5-≤50 nmol/L. Among the boys, a significant inverse association was found between serum vitamin D status and BMI-for-age (χ2 = 5.958; P = .016. Conclusions This study highlights the presence of a high prevalence of sub-optimal vitamin D status among urban primary school children in a tropical country. In light of the growing problem of obesity in Malaysian children, these findings emphasize the important need for appropriate interventions to address both problems of obesity and poor vitamin D status in children.

    Full Text Available Abstract Background Vitamin D deficiency is highly prevalent in both temperate as well as tropical countries. Obesity is one of the factors contributing to vitamin D deficiency. As our country has a high prevalence of overweight and obesity, we aimed to study serum 25-hydroxyvitamin D (25(OHD level and its association with adiposity using various adiposity indicators; and to study other risk factors that affect serum 25(OHD level among multi-ethnic adults in Kuala Lumpur, Malaysia. Methods This was a cross sectional study conducted with a multistage sampling. All permanent teachers working in government secondary schools in Kuala Lumpur were invited for the study. The data collection included serum 25(OHD, Parathyroid Hormone (PTH, body fat percentage, waist circumference, body mass index (BMI and blood pressure. Demographic characteristics, sun avoidance, sun exposure and physical activity were enquired from the participants using a self-administered questionnaire. The data was analyzed using a complex sample analysis. Results A total of 858 participants were recruited. Majority of them were Malays, females and had tertiary education. The overall prevalence of vitamin D deficiency (<20 ng/ml was 67.4 %. Indian participants (80.9 % had the highest proportion of vitamin D deficiency, followed by Malays (75.6 %, others (44.9 % and Chinese (25.1 %. There was a significant negative association between serum 25(OHD level with BMI (β = −0.23 and body fat percentage (β = −0.14. In the multivariate linear regression analysis, Malays, Indians and females (p < 0.001; higher BMI and larger waist circumference (p < 0.05 were significantly associated with lower serum 25(OHD level. The full model explained 32.8 % of the variation between participants in the serum 25(OHD level. The two most influential factors affecting serum 25(OHD level were ethnicity and gender.

    Qigong is highly favoured among Asian breast cancer survivors for enhancing health. This study examined the hypothesis that quality of life (QoL) in the Qigong group is better than the placebo (aerobic) or usual care group. A total of 197 participants were randomly assigned to either the 8-week Kuala Lumpur Qigong Trial or control groups in 2010-2011. Measurement taken at baseline and post- intervention included QoL, distress and fatigue. Analysis of covariance (ANCOVA) and Kruskal Wallis were used to examine for differences between groups in the measurements. There were 95 consenting participants in this 8week trial. The adherence rates were 63% for Qigong and 65% for the placebo group. The Qigong group showed significant marginal improvement in Quality of life scores compared to placebo (mean difference=7.3 unit; p=0.036), compared to usual care (mean difference=6.7 unit; p=0.048) on Functional Assessment Cancer Therapy-Breast measure. There were no significant changes between the placebo and usual care groups in fatigue or distress at post intervention (8-week). Cancer survivors who participated in the Qigong intervention showed slightly better QOL. Follow up studies are greatly needed to evaluate which subgroups may best benefit from Qigong. With a steep rise of cancer survivors, there is an urgent need to explore and engage more cultural means of physical activity to fight side effects of treatment and for cancer control in developing countries.

    2014-01-01

    Background This study aimed to investigate the prevalence of pregnancy experience and its association with contraceptive knowledge among single adults in a low socio-economic suburban community in Kuala Lumpur, Malaysia. Methods A cross-sectional survey was conducted in 2012 among the Kerinchi suburban community. Of the total 3,716 individuals surveyed, young single adults between 18 and 35 years old were questioned with regard to their experience with unplanned pregnancy before marriage. Contraceptive knowledge was assessed by a series of questions on identification of method types and the affectivity of condoms for the prevention of sexually transmitted diseases. Results A total of 226 female and 257 male participants completed the survey. In total, eight female (3.5%) participants reported experience with an unplanned pregnancy before marriage, and five male (1.9 %) participants had the experience of impregnating their partners. The participants had a mean total score of 3.15 (SD = 1.55) for contraceptive knowledge out of a possible maximum score of five. Female participants who had experienced an unplanned pregnancy had a significantly lower contraceptive knowledge score (2.10 ± 1.48) than who had never experienced pregnancy (3.30 ± 1.35), pknowledge score (1.60 ± 1.50) than those who did not have such experience (3.02 ± 1.59), pknowledge found in this study indicates the need for educational strategies designed to improve contraceptive knowledge.

    Food insecurity exists whenever people are not able to access sufficient food at all times for an active and healthy life. This study used the Radimer/Cornell hunger and food insecurity instrument to assess food insecurity and to determine the risk factors and consequences of food insecurity among low-income households in Kuala Lumpur. One hundred and thirty-seven Malay pre-school children (4-6 years old) from Taman Sang Kancil were measured for their weights and heights. Questionnaires were used to collect food security and socioeconomic information on the households. The findings indicated that 34.3% of the households were food secure, while 65.7% experienced some kind of food insecurity, (27.7% households were food insecure, 10.9% individuals were food insecure and 27.0% fell into the child hunger category). The prevalence of underweight, stunting and wasting were 44.5%, 36.5% and 30.7% respectively. The prevalence of high weight-for-height (overweight) was 13.1%. Based on multinomial logistic regression, larger household size (OR=1.418; phousehold food security levels. It is recommended that for the Malaysian population, the Radimer/Cornell hunger and food insecurity instrument should be modified and further validated with various ethnic groups in a variety of settings. The validation should include the appropriateness of the statements to the target grounds and their different risk factors and outcomes of food insecurity.

    In response to an absence of studies among refugees and host communities accessing highly active antiretroviral therapy (HAART) in urban settings, our objective was to compare adherence and virological outcomes among clients attending a public clinic in Kuala Lumpur, Malaysia. A cross-sectional survey was conducted among adult clients (≥18 years). Data sources included a structured questionnaire that measured self-reported adherence, a pharmacy-based measure of HAART prescription refills over the previous 24 months, and HIV viral loads. The primary outcome was unsuppressed viral load (≥40 copies/mL). Among a sample of 153 refugees and 148 host community clients, refugees were younger (median age 35 [interquartile range, IQR 31, 39] vs 40 years [IQR 35, 48], p refugee and host clients were refugees vs 16 % of host clients, p = 0.54). Refugee status was not independently associated with the outcome (adjusted odds ratio, aOR = 1.28, 95 % CI 0.52, 3.14). Overall, the proportions of refugee and host community clients with unsuppressed viral loads and sub-optimal adherence were similar, supporting the idea that refugees in protracted asylum situations are able to sustain good treatment outcomes and should explicitly be included in the HIV strategic plans of host countries with a view to expanding access in accordance with national guidelines for HAART.

    Control region polymorphisms in the mitochondrial DNA of 124 unrelated individuals from the Malay population living in or around Kuala Lumpur in Malaysia were investigated and phylogenetic haplogroup lineages were determined. The intergenic COII/tRNALys 9-bp deletion, 3010 and 5178 mutations, and several coding region polymorphisms were examined to discriminate some phylogenetic haplogroups. Sequence comparison of the control regions led to the identification of 117 mitochondrial haplotypes, in which 103 types were observed in only one individual and the other nine types were shared by more than two individuals. Gene diversity was estimated to be 0.997. Phylogenetic haplogroup determination revealed that the gene pool of the modern Malay population in Malaysia consisted mainly of southeast Asian, east Asian, unidentified and unique, and aboriginal southeast-specific haplogroups. These results suggest a multi-original nature for the modern Malay population. The present database may help not only in personal identification but also in determining geographic origin in forensic casework in Malaysian, Southeast Asian and East Asian populations.

    Depressive illness is common among the aged population. A case control study was conducted, focusing on risk factors influencing depression among the elderly. This study involved 130 elderly patients diagnosed to have depressive illness from the psychiatric clinics of Kuala Lumpur Hospital (HKL) and Universiti Kebangsaan Malaysia Hospital (HUKM). Another group of 130 elderly patients with no history of depressive illness were recruited from the medical specialist clinics. The majority of cases were female (75.4%), aged 60-74 years (92.3%) and from Chinese ethnic group (59.2%). Non-Malay elderly has three times risk (AOR 2.537, 95% CI 1.439-4.471) of suffering the depressive illness compared to the Malay elderly, the elderly with chronic health problems are more likely to be depressed compared to those who do not suffer from any chronic illness (p trend <0.001). Other risk factors identified were family history of depression with four times risk (AOR 4.225, 95% CI 2.017-8.848) and lower social support with eight times risk (AOR 7.949, 95% CI 2.588-24.417). Social support is not only important in encouraging the elderly to practice healthy life style but proven to influence the risk of getting depression among them. Hence, it is very crucial that the elderly is given total attention, respect and love from all parties to ensure prosperity and meaningfulness in life.

    Body weight of children is affected by many factors including food habits which are influenced by their parents. Studies in the West have shown that parents tend to control child feeding in response to their child's weight status. The aim of this study was to assess Malaysian parental concerns about child weight and the control they exert on child feeding. This cross-sectional study was conducted on parents and their children aged 9 to 12 years from a primary school in Kuala Lumpur. The weight status of the children was classified according to the body mass index-for-age growth chart. Parental concerns about child weight and control in child feeding was assessed using the adapted Malay version of Child Feeding Questionnaire. A total of 204 parents participated in this study. The study found that being a female served as a protective factor against becoming overweight (OR: 0.28, CI: 0.13-0.62). Parents with overweight children were significantly older (OR: 1.08, CI: 1.01-1.15), concerned about their child's weight (OR: 2.77, CI: 1.49-5.12) and controlled their child's feeding by restricting food intake (OR: 2.70, CI: 1.30-5.60). They were less likely to pressure their children to eat (OR: 0.32, CI: 0.19-0.56). Parents from the low income group were more likely to have underweight children (OR: 4.15, CI: 1.28-13.47). There was significant difference in level of parental concern across differing child weight status. Parents with overweight children were likely to be more concerned about their child's weight, tending to control their feeding. In contrast, parents with underweight children did not exert control on their feeding.

Female participants who had experienced an unplanned pregnancy had a significantly lower contraceptive knowledge score (2.10 ± 1.48) than who had never experienced pregnancy (3.30 ± 1.35), p<0.05. Likewise, male participants who had experienced impregnating their partners had a significantly lower contraceptive knowledge score (1.60 ± 1.50) than those who did not have such experience (3.02 ± 1.59), p<0.05. The results showed evidence of premarital unplanned pregnancy among this suburban community. The low level of contraceptive knowledge found in this study indicates the need for educational strategies designed to improve contraceptive knowledge.

    In support to the nation's goal of developing a liveable city, Malaysian government aims to improve the mobility in Kuala Lumpur by providing good quality transit services across the city. However, the public starts to demand for more than just a connectivity between two points. They want their transit journey to be comfortable and pleasant from the very first mile. The key here is the first and last mile (FLM) of the transit service which defines their journey to access the station itself. The question is, does the existing transit services' FLM satisfy public's needs? Therefore, many studies had emerged in attempt to assess the pedestrian-friendliness. While most of them did base on the pedestrian's perceptions, there were also studies that spatially measured the connectivity and accessibility to various landuses and point of interests. While both can be a good method, their integration could actually produce a better assessment. However, till date, only a few studies had attempted to do so. This paper proposes a framework to develop a Spatial Walkability Index (SWI) by integrating a multicriteria evaluation technique, Analytical Network Process (ANP) and network analysis on geographical information system (GIS) platform. First, ANP will aggregate the degree of importance for each walkability criteria based on the pedestrian's perceptions. Then, the network analysis will use the weighted criteria as attributes to find the walkable routes within half mile radius from each station. The index will be calculated by rationing the total length of walkable routes in respect to the available footpath. The final outcome is a percentage of walkable FLM transit routes for each station which will be named as the SWI. It is expected that the developed framework can be applied in other cities across the globe. It can also be improvised to suit the demand and purpose there.

    Background: The GReat-Child Trial was a quasi-experimental intervention that has emphasized whole grain as a strategy to manage childhood obesity. Methods: Two schools in Kuala Lumpur with similar demographic characteristics were assigned as intervention (IG) and control (CG). Eligibility criteria were overweight/obese children aged 9 to 11 years who had no serious co-morbidity. Children who reported consuming wholegrain foods in their 3-day diet-recall during screening were excluded. A total of 63 children (31 IG; 32 CG) completed the entire intervention program. The IG children underwent six 30-min nutrition education lessons and had school delivery of wholegrain food on a daily basis over a 12-week period. Parents of IG children attended 1-h individual diet counseling. Anthropometric outcomes including BMI-for-age z-score (BAZ), body fat percentage and waist circumference were measured at baseline [T0], post-intervention [T1] (3rd month) and follow-up [T2] (9th month).

    Full Text Available Abstract Background Vitamin D status, as indicated by 25-hydroxyvitamin D is inversely associated with adiposity, glucose homeostasis, lipid profiles, and blood pressure along with its classic role in calcium homeostasis and bone metabolism. It is also shown to be inversely associated with metabolic syndrome and cardiovascular diseases in western populations. However, evidence from the Asian population is limited. Therefore, we aim to study the prevalence of vitamin D insufficiency ( Methods This is an analytical cross sectional study. A total of 380 subjects were sampled and their vitamins D status (25-hydroxyvitamin D, fasting blood glucose, full lipid profile were assessed using venous blood. Systolic and diastolic blood pressure, weight, height and waist circumference were measured following standard protocols. Socio-demographic data such as sex, age, smoking status etc were also collected. Data was analysed using t-test, chi-square test, General Linear Model and multiple logistic regression. Results Females made up 58% of the sample. The mean age of respondents was 48.5 (SD 5.2 years. Females had significantly lower mean Vitamin D levels (36.2; 95% CI: 34.5, 38.0 nmol/L compared to males (56.2; 95% CI: 53.2, 59.2 nmol/L. Approximately 41% and 87% of males and females respectively had insufficient ( Conclusions Our results highlight the high prevalence of vitamin D insufficiency among Malay adults in Kuala Lumpur.

    The human alphacoronaviruses HCoV-NL63 and HCoV-229E are commonly associated with upper respiratory tract infections (URTI). Information on their molecular epidemiology and evolutionary dynamics in the tropical region of southeast Asia however is limited. Here, we analyzed the phylogenetic, temporal distribution, population history, and clinical manifestations among patients infected with HCoV-NL63 and HCoV-229E. Nasopharyngeal swabs were collected from 2,060 consenting adults presented with acute URTI symptoms in Kuala Lumpur, Malaysia, between 2012 and 2013. The presence of HCoV-NL63 and HCoV-229E was detected using multiplex polymerase chain reaction (PCR). The spike glycoprotein, nucleocapsid, and 1a genes were sequenced for phylogenetic reconstruction and Bayesian coalescent inference. A total of 68/2,060 (3.3%) subjects were positive for human alphacoronavirus; HCoV-NL63 and HCoV-229E were detected in 45 (2.2%) and 23 (1.1%) patients, respectively. A peak in the number of HCoV-NL63 infections was recorded between June and October 2012. Phylogenetic inference revealed that 62.8% of HCoV-NL63 infections belonged to genotype B, 37.2% was genotype C, while all HCoV-229E sequences were clustered within group 4. Molecular dating analysis indicated that the origin of HCoV-NL63 was dated to 1921, before it diverged into genotype A (1975), genotype B (1996), and genotype C (2003). The root of the HCoV-229E tree was dated to 1955, before it diverged into groups 1-4 between the 1970s and 1990s. The study described the seasonality, molecular diversity, and evolutionary dynamics of human alphacoronavirus infections in a tropical region. © The American Society of Tropical Medicine and Hygiene.

    Many studies have suggested that sputum smear conversion after 2 months of antituberculosis treatment is an important determinant of treatment success and can be a predictor for relapse. The objective of this study is to determine the factors that influence sputum smear conversion after 2 months of treatment among pulmonary tuberculosis patients receiving treatment in the Institute of Respiratory Medicine in Kuala Lumpur, Malaysia. A total of 75 cases and 75 controls were interviewed, and their medical records were retrieved in order to extract the information needed. All analyses were conducted using SPSS version 17, and binary logistic regression analysis was used to determine the predictors of sputum smear nonconversion. Results showed that the following factors were associated with sputum smear positivity after 2 months of intensive treatment: diabetes mellitus (p=.013, odds ratio [OR]=2.59, 95% confidence interval [CI] 1.27-5.33), underweight body mass index (p=.025, OR=1.67, 95% CI 0.80-3.49), nonadherent to tuberculosis treatment (p=.024, OR=2.85, 95% CI 1.21-6.74), and previous history of tuberculosis (p=.043, OR=2.53, 95% CI 1.09-5.83). Multivariable analysis identified diabetes mellitus (p=.003, OR=4.01, 95% CI 1.61-9.96) as being independently associated with the risk of persistent sputum smear positivity after 2 months of intensive treatment. Based on the findings, identification of these factors is valuable in strengthening the management and treatment of tuberculosis in Malaysia in the future. This study emphasizes the importance of diabetes screening and integration of diabetic controls among tuberculosis patients in achieving better treatment outcome.

    blood pressure (bP) control among Malaysian is poor and doctor's adherence to clinical practice guideline (cPG) has been a well-known factor that may improve it. this study was designed to evaluate patients' bP control, doctors' adherence to the latest hypertension cPG and their association. Factors associated with bP control and cPG adherence was also examined. A cross-sectional study was conducted in Kuala Muda district's health clinics. 331 medical records were selected using stratified random sampling and standard proforma was used for data collection. the latest edition of the Malaysian cPG on hypertension was employed to define related variables. A total of 160 patients (48.3%) had controlled bP and it was significantly associated with patients' age (adjusted Odds ratio, aOr= 1.03, 95% cI: 1.004, 1.05, p= 0.016) and systolic bP at presentation (aOr= 0.95, 95% cI: 0.93, 0.96, p< 0.001). About 60.7% of the medical records showed doctor's good level of cPG adherence. this adherence has significant association with presence of chronic kidney disease (aOr= 0.51, 95% cI: 0.31, 0.85, p= 0.007) and cardiovascular disease (aOr= 2.68, 95% cI: 1.04, 6.95, p= 0.030) in the patients and physicians' treatment intensification (aOr= 2.00, 95% cI: 1.26, 3.19, p= 0.009). However, no association was found between bP control and cPG adherence. Hypertension control in this study was poor and the prevalence of physicians with good level of cPG adherence was slightly above average. these findings are important for relevant stakeholders to strategise an action plan to improve hypertension management outcome.

    Despite the worldwide circulation of human coronavirus OC43 (HCoV-OC43) and HKU1 (HCoV-HKU1), data on their molecular epidemiology and evolutionary dynamics in the tropical Southeast Asia region is lacking. The study aimed to investigate the genetic diversity, temporal distribution, population history and clinical symptoms of betacoronavirus infections in Kuala Lumpur, Malaysia between 2012 and 2013. A total of 2,060 adults presented with acute respiratory symptoms were screened for the presence of betacoronaviruses using multiplex PCR. The spike glycoprotein, nucleocapsid and 1a genes were sequenced for phylogenetic reconstruction and Bayesian coalescent inference. A total of 48/2060 (2.4 %) specimens were tested positive for HCoV-OC43 (1.3 %) and HCoV-HKU1 (1.1 %). Both HCoV-OC43 and HCoV-HKU1 were co-circulating throughout the year, with the lowest detection rates reported in the October-January period. Phylogenetic analysis of the spike gene showed that the majority of HCoV-OC43 isolates were grouped into two previously undefined genotypes, provisionally assigned as novel lineage 1 and novel lineage 2. Sign of natural recombination was observed in these potentially novel lineages. Location mapping showed that the novel lineage 1 is currently circulating in Malaysia, Thailand, Japan and China, while novel lineage 2 can be found in Malaysia and China. Molecular dating showed the origin of HCoV-OC43 around late 1950s, before it diverged into genotypes A (1960s), B (1990s), and other genotypes (2000s). Phylogenetic analysis revealed that 27.3 % of the HCoV-HKU1 strains belong to genotype A while 72.7 % belongs to genotype B. The tree root of HCoV-HKU1 was similar to that of HCoV-OC43, with the tMRCA of genotypes A and B estimated around the 1990s and 2000s, respectively. Correlation of HCoV-OC43 and HCoV-HKU1 with the severity of respiratory symptoms was not observed. The present study reported the molecular complexity and evolutionary dynamics of human

    The emergence of drug-resistant tuberculosis (TB) is a major public health threat. However, little is known about the predictors of death in drug-resistant TB in Malaysia. This study aimed to determine the predictors of death in drug-resistant TB patients, including multidrug-resistant TB (MDR-TB), in Kuala Lumpur, Malaysia. This study adopted a retrospective cohort study design and involved laboratory-confirmed drug-resistant TB patients (n=426) from January 2009 to June 2013. A Cox regression model and Kaplan-Meier curves were used to model the outcome measure. Data were analysed by using SPSS v.20.0 for Windows. In this study, 15.3% (n=65) of the patients died. Among the study patients, 70.9% were monoresistant TB cases, 9.4% were poly-resistant TB and 19.7% were MDR-TB. MDR-TB [adjusted hazard ratio (aHR)=2.23, 95% confidence interval (CI) 1.26-3.95], ethnicity [Malay (aHR=5.95, 95% CI 2.30-15.41), Chinese (aHR=4.01, 95% CI 1.38-11.66) and Indian (aHR=3.76, 95% CI 1.19-11.85)], coronary heart disease (aHR=6.82, 95% CI 2.16-21.50), drug abuse (aHR=3.79, 95% CI 2.07-6.93) and treatment non-compliance (aHR=1.81, 95% CI 1.01-3.27) were independent predictors of poorer survival in the multivariate Cox regression analysis. This study suggests that MDR-TB, local ethnicity, coronary heart disease, history of drug abuse and treatment non-compliance are factors predicting poor survival in drug-resistant TB patients. More emphasis should be given to the management of drug-resistant TB patients with these characteristics to achieve better treatment outcomes.

    Group B Streptococcus (GBS) infection was studied in 49 patients collected at convenience (convenience sampling), excluding infants and women with genital tract- and pregnancy-related isolates, according to the availability of stocked isolates and easy accessibility to epidemiological data. The data were examined both prospectively and retrospectively from 2003-2005 at a tertiary-level multidisciplinary hospital in Kuala Lumpur, Malaysia. Skin and soft-tissue infections in 35 patients (71.4%) were the most common clinical presentation, while diabetes mellitus was the most common underlying condition (35 patients, 71.4%). All GBS isolates were sensitive to penicillin, and most isolates tested were sensitive to erythromycin (97.7%). Serotyping of 45 GBS isolates using a commercial serotyping kit revealed that the most common serotype was Ia (22.2%), followed by VI (17.8%), III and V (13.3% each). Others included Ib, II, IV, VIII, and VII; 13.3% were nontypeable. The findings of this pilot study are limited by the small sample size, the sampling method and the possibility that the cases are not wholly representative of the University Malaya Medical Centre population. Further studies from our hospital with larger numbers and using probabilistic sampling techniques are required to confirm the relatively high occurrence of serotype VI (the second most common serotype) in the population studied.

    A Coordinated Research Programme (CRP) on assessment of environmental exposure to mercury in selected human populations as studied by nuclear and other techniques was initiated by the IAEA in 1990 in collaboration with WHO. The purpose of this CRP is to promote national and regional studies to evaluate the exposure of selected population groups to mercury and methylmercury and to estimate potential health risks in these groups. The programme is focused on the analysis of human head hair for the determination of mercury and methylmercury. This CRP has two main components: (i) identifying population groups that are at risk, and (ii) studying health effects in the exposed persons, particularly pregnant women and the babies born to them. This report contains the discussions held during the second Research Co-ordination Meeting (RCM) for the CRP which took place in Kuala Lumpur, Malaysia, under the sponsorship of the University Kebangsaan Malaysia and papers presented at this meeting.

Investigation of potential failure and determination of the slope sensitivity with regard to safety, reliability and economics were parts of this study. Ground anchor is designed to support a structure in this study. Ground anchor were implemented at the Mechanically Stabilized Earth (MSE) wall along Anak Persiaran Jubli Perak to overcome the further cracking of pavement parking, concrete deck and building of the Apartments. A result from the laboratory testing of soil sample such as index test and shear strength test were applied to the Slope/W software with regard to the ground anchors that were implemented. The ground anchors were implemented to increase the value of the factor of safety (FOS) of the MSE Wall. The value of the factor of safety (FOS) before implementing the ground anchor was 0.800 and after the ground anchor was implemented the value increase to 1.555. The increase percentage of factor of safety by implementing on stability of slope was 94.38%.

  3. Sediment trace metal concentrations from the mudflats of Kuala Juru and Kuala Muda of Malaysia

    Energy Technology Data Exchange (ETDEWEB)

    Mat, I.; Maah, M.J. (Univ. of Malaya, Kuala Lumpur (Malaysia))

    1994-11-01

    About 4-5000 ha of the mudflats along the western coast of Peninsular Malaysia are currently utilized for the semi-culture of the economically important marine bivalve, Anadara granosa. Therefore, information on the status of the trace metal pollution in the culture areas is of considerable value in the interest of public health when shellfish from this area are available for consumption. As an initial assessment of the degree of trace metal pollution in the sediments, an approach to analyze the non-residual (non-lattice held) trace metal concentrations should be of prime consideration rather than the total metal content in the sediments. This approach has the advantage that it is not necessary to restrict the comparison of the non- residual metal fraction to sediments having similar textural composition. For the above reasons, assorted acids are used to partially extract the non-residual trace metal fraction. The partial extraction of sediment-bound trace metals is not only providing information on the strength of association between metals and sediment compositions but also the potential availability of these metals to aquatic organisms. It has been shown that the bioavailability of trace metals to the aquatic biota is best related to the easily leachable, non-residual fraction rather than the total sediment bound trace metals. Therefore, it makes very little sense to consider the total metal content in the sediment to be bioavailable to cause damage to aquatic organisms or to the aquatic ecosystems. 12 refs., 1 fig., 3 tab.

Duration of symptoms, type of organism, type of joint drainage, presence of preexisting joint problems and presence of osteomyelitis are among the important factors with prognostic significance. Seventy three percent of patients with less than 7 days duration of symptoms had satisfactory results. Whereas when the duration of symptoms exceeded 7 days, 75% of the patients had unsatisfactory outcome. All cases with poor outcome had positive cultures. Staphylococcus aureus was responsible for 77% of the culture-positive cases. All Staphylococcus aureus in this study were penicillin-resistant but sensitive to cloxacillin. There were 3 instances where Staphylococcus became resistant to cloxacillin following recurrence of septic arthritis. However, they were still sensitive to third generation cephalosporin. Staphylococcus aureus was capable of producing poor results even when the case was treated early. Other organisms were gram-negative bacilli which infect patients with suppressed immune system, that is, intravenous drug abuser, systemic steroid therapy and diabetes mellitus. Open arthrotomy was the method of drainage used in all hip sepsis. This method was also the most reliable method of joint drainage in other joints compared to aspiration method when frank pus was already present. Most immuno-compromised patients recovered badly from septic arthritis. Associated adjacent osteomyelitis, preexisting chronic arthritis and recent intra-articular fractures were also noted to adversely affect the functional outcome.

    The solar ultraviolet A (UVA) radiation data was measured at Physics Building, Universiti Kebangsaan Malaysia (2 degree sign 55' N, 101 degree sign 46' E, 50m asl) by the Xplorer GLX Pasco that connected to UVA Light sensor. The measured solar UVA data were compared with the total daily solar ultraviolet B (UVB) radiation data recorded by the Malaysian Metrological Department at Petaling Jaya, Malaysia (3 degree sign 06' N, 101 degree sign 39' E, 50m asl) for 18 days in year 2007. The daily total average of UVA radiation received is (298±105) kJm -2 while the total daily maximum is (600±56) kJm -2 . From the analysis, it shows that the values of UVA radiation data were higher than UVB radiation data with the average ratio of 6.41% between 3-14%. A weak positive correlation was found (the correlation coefficient, r, is 0.22). The amount of UVA radiation that reached the earth surface is less dependence on UVB radiation and the factors were discussed.

    Various hydrological and meteorological variables such as rainfall and temperature have been affected by global climate change. Any change in the pattern of precipitation can have a significant impact on the availability of water resources, agriculture, and the ecosystem. Therefore, knowledge on rainfall trend is an important aspect of water resources management. In this study, the regional annual and seasonal precipitation trends at the Langat River Basin, Malaysia, for the period of 1982-2011 were examined at the 95 % level of significance using the regional average Mann-Kendall (RAMK) test and the regional average Mann-Kendall coupled with bootstrap (RAMK-bootstrap) method. In order to identify the homogeneous regions respectively for the annual and seasonal scales, firstly, at-site mean total annual and separately at-site mean total seasonal precipitation were spatialized into 5 km × 5 km grids using the inverse distance weighting (IDW) algorithm. Next, the optimum number of homogeneous regions (clusters) is computed using the silhouette coefficient approach. Next, the homogeneous regions were formed using the K-mean clustering method. From the annual scale perspective, all three regions showed positive trends. However, the application of two methods at this scale showed a significant trend only in the region AC1. The region AC2 experienced a significant positive trend using only the RAMK test. On a seasonal scale, all regions showed insignificant trends, except the regions I1C1 and I1C2 in the Inter-Monsoon 1 (INT1) season which experienced significant upward trends. In addition, it was proven that the significance of trends has been affected by the existence of serial and spatial correlations.

    Most studies regarding to air pollution were focused on forecasting Air Pollutant Index (API). Yet, there were no studies that conducted in Malaysia focused on Health-Related Quality of Life (HRQoL). The aim of this study was to investigate the HRQoL in two urban cities, which are Shah Alam and Putrajaya with different air pollution index. In doing so, SF36v2 questionnaire has been utilized to elicit data on HRQoL domains measured using eight domains (Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional and Mental Health). A cross-sectional study was conducted and residents were selected using simple random sampling from Shah Alam and Putrajaya. The SF36v2 questionnaire with socio demographic information was distributed to the residents. A total of 266 participated in the study, of which 133 samples per groups. The statistical methods employed were descriptive analyses, independent samples t-test and MANOVA to analyze the HRQoL data. There was no difference in perceptions on HRQoL for Role Physical, Vitality, Social Functioning and Mental Health between residents in Shah Alam and residents in Putrajaya. However, there was difference in perception on HRQoL for Physical Functioning, Bodily Pain, General Health and Role Emotional.

  16. ABSORPTION AND PERMEABILITY PERFORMANCE OF SELANGOR RICE HUSK ASH BLENDED GRADE 30 CONCRETE

    KARTINI, K.

    2010-03-01

    Full Text Available Substituting waste materials in construction is well known for conservation of dwindling resources and preventing environmental and ecological damages caused by quarrying and depletion of raw materials. Many researches had shown that some of these wastes have good pozzolanic properties that would improve the quality of concrete produced. One such waste material is agricultural waste rice husk, which constitute about one-fifth of 600 million tonnes of rice produced annually in the world. The RHA obtained by burning the rice husk in the ferrocement furnace and used as a cement replacement material. The use of this supplementary cementing material is expected to meet the increase in demand of cement, as the current world cement production of approximately 1.2 million tonnes is expected to grow exponentially to about 3.5 billions tonnes per year by 2015. This paper reports the results of durability performance conducted on the normal strength concrete specimens of 30 N/mm2 containing 20% or 30% RHA by cement weight, with or without addition of superplasticizer. The results show that replacement of cement with RHA lowers initial surface absorption, lowers the permeability, lowers the absorption characteristics, longer time taken for the capillary suction resulted in lower sorptivity value, lower water permeability and increase the resistance of concrete to chloride ion penetration in comparison with the OPC control concrete. The present investigations revealed that incorporation RHA significantly improve the absorption and permeability characteristics of concrete.

    The increasing trend of extensively drugresistant gram negative bacteria responsible for nosocomial infections has prompted resurgence colistin usage. Colistin-induced nephrotoxicity is a concern with disparity in the reported rates between previous studies. This study aims to evaluate colistin-induced nephrotoxicity among Malaysian population. The medical records of ICU patients receiving colistin therapy in Hospital Serdang and Hospital Sungai Buloh from 2010 to 2012 were retrospectively reviewed. Demographics data, treatment characteristic as well as culture result and creatinine level were documented. Nephrotoxicity was determined based on RIFLE criteria. A total of 100 patients were included. Median daily dose, cumulative dose and duration of colistin therapy were 3.0 MIU (IQR: 4, range 1-12), 17.8 MIU (IQR: 31.5, range 2-180) and seven days (IQR: 4, range 1-30). Nephrotoxicity was found in 23% of the study population. All cases were reversible but marginally associated with higher mortality. No statistical association exist between age, gender and race as well as administration routes with nephrotoxicity by univariable analysis. The association of dose and duration with nephrotoxicity was also not significant by univariable analysis. After adjustment for confounders, statistical association between the independent variables and dependent variable remains not significant. Lower dose and shorter duration in local settings contribute to lack of association between colistin therapy and nephrotoxicity in this study. Higher dosing regimen with loading dose application has been introduced in the latest National Antibiotic Guideline. Further evaluation of colistin-induced nephrotoxicity and potential risk factors is therefore warranted.

    This study was conducted to determine the prevalence of household food insecurity and its potential risk factors and outcomes among the Orang Asli (Temuan) households. Socioeconomic, demographic and food security information of the households and anthropometric measurements and dietary intakes of preschoolers (n = 64) were obtained using a structured questionnaire. Food security was assessed using the Radimer/Cornell hunger and food insecurity instrument. Diet quality was based on 24 hour recall and analyzed according to the Malaysian RDA and Food Guide Pyramid. Majority of the households (82%) reported some kind of household food insecurity. The prevalence of significant underweight, stunting and wasting were 45.3%, 51.6% and 7.8%, respectively. Dietary intakes were less than 2/3 RDA levels for calories, calcium and iron. However, the intakes of protein, vitamin A, vitamin C and niacin exceeded the RDA and the sources for these nutrients were mainly rice, fish and green leafy vegetables. Among the five food groups, only the number of servings from cereals/cereal products/tubers group was achieved while that of the milk/diary products was the worst. Majority of the children (68.7%) had poor, 31.3% had fair and none with excellent diet quality. In general, diet quality and nutritional status of the children decreased as household food insecurity worsened. It is recommended that the nutritional problems of Orang Asli children be addressed through health, nutrition and economic programs and further studies should be carried out on determinants and consequences of household food insecurity.

    Avicennia marina saplings were established within a restoration area at Sg. Hj. Dorani, Malaysia between May and August 2010. Sapling establishment was achieved following the construction of segmented and hard breakwater as mitigating measure against coastal erosion. Geostructures known as brush faschines were installed within the restoration area as secondary sediment and seed traps. There was a steady increase in the sand content of the soil from 5% in November 2008 to 18% in May 2010. The dominant soil content was silt but it fluctuated and declined slightly over the same period, between 80% in November 2008 and 72% in May 2010. The accreting shoreline behind the breakwater had stabilised within 18 months. Subsequently, the first batch of A. marina wild seedlings or wildings was established on the mud surface in September 2009. Only about 10% of these wildings survived and showed high survival rate (90%) over the next eight months. Wildings that were naturally established near mother trees showed good growth performance. No wilding was established after the fruiting season in August 2010 as all seeds that were dispersed into the restoration area were washed away by September 2010. Tall, A. marina wild saplings (1 m) planted within the restoration area showed higher survival rate (80%) compared to planted saplings of Rhizophora apiculata (30%). Final planting of a thousand 1 m tall A. marina wild saplings was carried out from June 2010, in clumps of 20 and in 1 m × 1 m spacing. By the end of September 2010 clusters of regenerating A. marina mangroves about 1.5 m tall were successfully established on the accreting coastline.

    Full Text Available Environmental contamination by petroleum hydrocarbons, mainly crude oil waste from refineries, is becoming prevalent worldwide. This study investigates the bioremediation of water contaminated with crude oil waste. Bacillus salamalaya 139SI, a bacterium isolated from a private farm soil in the Kuala Selangor in Malaysia, was found to be a potential degrader of crude oil waste. When a microbial population of 108 CFU ml-1 was used, the 139SI strain degraded 79% and 88% of the total petroleum hydrocarbons after 42 days of incubation in mineral salt media containing 2% and 1% of crude oil waste, respectively, under optimum conditions. In the uninoculated medium containing 1% crude oil waste, 6% was degraded. Relative to the control, the degradation was significantly greater when a bacteria count of 99 × 108 CFU ml-1 was added to the treatments polluted with 1% oil. Thus, this isolated strain is useful for enhancing the biotreatment of oil in wastewater.

    2016-01-01

    Full Text Available Activities of Po-210 in cockles Anadara granosa around Peninsular Malaysia have been determined by Alpha Spectrometry using a radiochemical separation technique. The results showed that Po-210 activity distribution varies according to sampling sites. The range of activity was 2.61 ± 1.50 to 309 ± 26 Bq/kg. The lowest mean was recorded from Kuala Selangor and the highest mean was from Mersing. The activity pattern shown by this radionuclide was a decrease with an increase in cockles mass. The activity was higher in cockles of smaller sizes than the larger sized cockles, a pattern attributed to their digestion and metabolism system. The activity intake and effective dose was found to be less than international guidelines and seafood intake was considered safe for human consumption. These findings suggest that regular monitoring should be carried out to help reduce morbidity and mortality among humans as a result of occasional seafood consumption.

    Increasing use of pesticides in agriculture to control pest may result in permanent damage to the environment and consequently cause harmful health problems especially among infant and children. Due to pesticide's natural toxicity and its widespread use, it causes a serious threat to public health especially to this vulnerable group. The purpose of this study was to determine the organophosphorus pesticide urinary metabolite levels and its predictors among Orang Asli children of the Mah Meri tribe living in an agricultural island in Kuala Langat, Selangor. Data collection was carried out at an island in Kuala Langat, Selangor, where a total of 180 Orang Asli children of the Mah Meri tribe voluntarily participated in the study. Data were collected via a validated, modified questionnaire. Urinary organophosphate metabolites, namely dimethylphosphate, diethylphosphate, dimethylthiophosphate, dimethyldithiophosphate, diethylthiophosphate, and diethyldithiophosphate were measured to assess organophosphate pesticide exposure in children. Eighty-four (46.7%) of the respondents were positive for urine dialkyl phosphate metabolites. In multivariable analysis, children who frequently consumed apples had 4 times higher risk of pesticide detection than those who consumed apple less frequently. In addition, those who frequently ate cucumbers had 4 times higher risk for pesticide detection than those who ate cucumbers less frequently. Children with a father whose occupation involved high exposure to pesticides (agriculture) had 3 times higher risk of pesticide detection than those with a father in a low-risk occupation (nonagriculture). Almost half of the children (46.7%) in the study area tested positive for urinary dialkyl phosphate metabolite levels. Most of the metabolite levels were equal to or higher than that reported in other previous studies. Major factors associated with pesticide detection in children in this study were frequent intake of apple and cucumber and

A majority of participants had poor knowledge level (57.0%, unacceptable attitudes (90.3% and unacceptable preventive practices (69.1% on leptospirosis, and only 29.7% knew “rat-urine disease” as leptospirosis. Only 34.2% of the participants knew the bacteria could enter via wound lesions. Ethnicity and income were strongly associated with knowledge level and preventive practices, respectively (p-values < 0.05. As for attitudes, ethnicity, income and education type were significantly associated (p-values < 0.05. Only 36.5% of the participants were willing to see a doctor and did not mind if their house or surrounding area is dirty (59.7%. Surprisingly, only 32.9% had used rubber boots during floods. By logistic regression analysis, ethnicity was the only significant predictor for both knowledge level (an odds ratio (AOR = 0.39, 95% confidence interval (CI = 0.222–0.680 and preventive practices (AOR = 1.81, 95% CI = 1.204–2.734. Ethnicity (AOR = 0.40, 95% CI = 0.239–0.665, income (AOR = 1.58, 95% CI = 1.041–2.385 and education type (AOR = 3.69, 95% CI = 1.237–10.986 were strong predictors for attitudes. Among the KAP variables, attitude (AOR = 4.357, 95% CI = 2.613–7.264 was the only predictor for the preventive practices by logistic regression analysis. The KAP elements on leptospirosis are still lacking and poor health seeking behavior and attitudes are of our utmost concern. Thus, effective strategies should be planned to impart knowledge, and develop proactive approaches and good preventive modules on leptospirosis to this leptospirosis-prone community.

    Since the beginning of the nuclear age, Cesium-137 has become a part of the world's ecosystems. Cs-137 is carried from the atmosphere to the ground by rainfall. On reaching the earth's surface, 137 Cs becomes strongly adsorbed to soil profiles and is concentrated predominantly in the surface layer, particularly in clayey soils. Systematic measurements of Cs-137 levels will therefore permit estimates to be made of the cumulative effects of soil redistribution over the past 25 years. Sediment movement in river catchments and coastal areas is a very old problem in Malaysia. In view of rapid development of urban and agricultural areas in Malaysia it was realised tha soil loss problems are particularly serious. The Sungai Lui catchment was chosen to be the investigational site. Geologically, the area comprises of granite and granitic schist. The area is mostly covered by forest (approx. 83%) and rubber (13%), padi (2%) and others (2%). The climate is considered to be typical of Peninsular Malaysia (equatorial) characterised by uniform temperature, high humidity and high rainfall. The area is mainly drained by the Lui River. Soil samples were collected from the catchment area at 4 sampling points in April 1981. The results of analyses of Cs-137 in soil samples from Sungai Lui catchment area ranged from 1.3 to 6.8 M Bq g -1 of sample and they could still be detected even up to 20 cm depth. A general pattern of Cs-137 distribution was observed in the soil profile at each site. The highest activity being in the top 3 cm layer and then decreasing up to about 6 cm. The activity increases again up to about 9 cm layer. From there onwards, it decreases. Based on these results, the estimated rate of sediment accumulation in the area was found to be about 0.47 cm/year. Since the samples were only collected from the depositional sites, further sampling especially from erosional site should therefore be carried out in order to obtain more complete data

    Campylobacter is a major foodborne pathogen frequently associated with human bacterial gastroenteritis in the world. This study was conducted to determine the prevalence and antibiotic resistance of Campylobacter spp. in the beef food system in Malaysia. A total of 340 samples consisting of cattle feces (n = 100), beef (n = 120) from wet markets and beef (n = 120) from hypermarkets were analyzed for Campylobacter spp. The overall prevalence of Campylobacter was 17.4%, consisting of 33% in cattle fecal samples, 14.2% in raw beef from wet market and 7.5% in raw beef from the hypermarket. The multiplex-polymerase chain reaction (PCR) identified 55% of the strains as C. jejuni, 26% as C. coli, and 19% as other Campylobacter spp. A high percentage of Campylobacter spp. were resistant to tetracycline (76.9%) and ampicillin (69.2%), whilst low resistance was exhibited to chloramphenicol (7.6%). The MAR Index of Campylobacter isolates from this study ranged from 0.09 to 0.73. The present study indicates the potential public health risk associated with the beef food system, hence stringent surveillance, regulatory measures, and appropriate interventions are required to minimize Campylobacter contamination and prudent antibiotic usage that can ensure consumer safety.

    This paper examines whether attitudes towards electric vehicles (ATEVs), subjective norms (SNs) and perceived behavioural control (PBC) have significant associations with consumer purchase intention (PI) and the purchase behaviour of environmentally friendly vehicles (EFVs). The results from the survey questionnaires are analysed using confirmatory factor analysis (CFA) and structural equation modelling (SEM). The findings of this paper indicate that ATEV, SN and PBC significantly influence PI. This finding also indicates that environmental consequence and individual preferences do not influence the PI of the respondents. We found that Malaysian car owners are largely unaware of the greenhouse effects on the environment or attach to it little importance, which is reflected in their PI towards EFVs. The outcomes of this study could help policymakers design programmes to influence attitudes, subjective norms, perceived behavioural control and purchase behaviour to prevent further air pollution and reduce CO2 emissions from the transportation sector.

    Full Text Available The paper analyzes the relationship between beta risk and aggregate market volatility for 12sized-based portfolios for the case of Malaysia using daily data from January 1988 to December 2000. The analysis is conducted for the entire sample as well as various sub-samples corresponding to (ithe upward trend in the market from January 1988-December 1992; (ii the huge influx of portfolio investments from January 1993-June 1997, and (Hi the Asian crisis and its aftermath from July 1997-December 2000. The results generally suggest instability in beta risk due to its significant response to aggregate market volatility. Additionally, we also note that the direction of relationship between beta risk and market volatility seems to depend on stock market conditions or sub-samples used. Namely, beta risk seems to decrease with increasing market volatility for the whole sample as well as the first and the third sub-samples. However, for the second sub-sample, their relationship turns to be positive. Lastly, the author have evidence for the Malaysian case that size does not play significant role in the way beta risk responds to aggregate market volatility. These results have important implications for investment decisions as well as for event analyses employing the market model to generate abnormal returns.

    The application of the Geographic Information Systems (GIS) to the study of vector transmitted diseases considerably improves the management of the information obtained from the field survey and facilitates the study of the distribution patterns of the vector species. As part of a study to assess remote sensing data as a tool for vector mapping, geographical features like rivers, small streams, forest, roads and residential area were digitized from the satellite images and overlaid with entomological data. Map of larval breeding habitats distribution and map of malaria transmission risk area were developed using a combination of field data, satellite image analysis and GIS technique. All digital data in the GIS were displayed in the WGS 1984 coordinate system. Six occasions of larval surveillance were also conducted to determine the species of mosquitoes, their characteristics and the abundance of habitats. Larval survey studies showed that anopheline and culicine larvae were collected and mapped from 79 and 67 breeding sites respectively. Breeding habitats were located at 100-400 m from human settlement. Map of villages with 400 m buffer zone visualizes that more than 80% of Anopheles maculatus s.s. immature habitats were found within the buffer zone. This study amplifies the need for a broadening of the GIS approach which is emphasized with the aim of rejuvenating the dynamic aspect of entomological studies in Malaysia. In fact, the use of such basic GIS platforms promote a more rational basis for strategic planning and management in the control of endemic diseases at the national level.

    Full Text Available A research was conducted to study the factors affecting the alighting and boarding rate of passengers and establish a prediction model for alighting and boarding time of passengers for a passenger rail service in Malaysia. Data was collected at the KL Sentral LRT station during the morning and evening peak hours for a period of 5 working days. Results show that passenger behaviour, passenger volume, crowdedness in train and mixture of flow has significant effects on the alighting and boarding time though mixture of flow is not significant in the prediction model produced due to the passenger behaviour at the platform.

    The study reported served 2 purposes: 1) to assess the amount of sexual information posessed by a sample of staff nurses working for the National Family Planning Board and the Public Health Dept., and 2) to gather local normative data on the Information Subtest of the Derogatis Sexual Functioning Inventory (DSFI). The subjects for the this study were 2 groups of staff nurses. 10 were employees of the National Family Planning Board currently working in 1 of its clinics and 25 were public health nurses who were at a 1 week training at the clinic. The research was a questionnaire type study. Each subject was given the DSFI. On the Information Subtest of the DSFI the subjects obtained a mean score of 12.7 with a standard deviation of 4.2. This score is much lower than the normative mean (American population) and the sexually dysfunctional women mean. The nurses had inadequate and inaccurate knowledge about anatomy, physiology and psychology of sexual relations. Error analysis revealed that as a group they had poor understanding about male sexuality, the effect of aging on sexuality fertility and menopause, and difficulty in accepting oral-genital sex and sexual fantasies. This study recommends that these nurses, in order to more effective in their work, should be trained in the area of human sexuality. This training must include not only the physiology of sex but also the human aspects of sexual union.

    An increasing demand of platinum group elements (PGE) especially platinum, palladium and rhodium in various industries has increased its concentration in the environment. Determination of PGE was measured in selected open and close sites using inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS). Results showed that Pt concentration in road dusts of open sampling area are in the range of not detected (ND) to 200.0 ng/ g, while the concentration of Rh is in the range of 8.02 ng/ g to 97.32 ng/ g. Pt and Rh in close sampling area, Genting Sempah Tunnel are in the range of not detected (ND) to 105.7±61.1 ng/g and 8.4±1.3 ng/ g to 59.0±5.5 ng/ g respectively. The ratio of Pt to Rh in road dusts samples ranges from 1.2: 1 to 7: 1, while the ratio in catalytic converter samples is 7: 1. There is no Pd detected in any of the samples taken. The correlation between Pt, Rh and traffic-related elements with the traffic density of the sampling sites were discussed. (author)

    For many years, Malaysia has been a strong and supportive partner of the IAEA. On the non-proliferation front, Malaysia is party to the NPT, with a comprehensive safeguards agreement in force. In November 2005, Malaysia also signed the additional protocol to its safeguards agreement. In the field of safety, Malaysia is a party to the conventions on early notification and assistance in the case of an accident or radiological emergency. Malaysia also participates in the Asian Nuclear Safety Network. The IAEA has a large and active technical cooperation (TC) programme in Malaysia. For example, the IAEA has been supporting the use of isotope hydrology in Malaysia to combat groundwater contamination in industrial sites. Last year we were also active in the health sector in Malaysia, supporting training and workforce development in the use of positron emission tomography. We are supporting the establishment of a Malaysian cyclotron facility for radioisotope production. The most recent such development was the establishment of a laboratory for the application of radiation in nanotechnology. And Malaysia plays an important role in hosting conferences, workshops and training courses in areas such as non-destructive testing, radiation safety, tissue grafts, regional electronic networking and the maintenance of nuclear instruments. The need to ensure adequate and reliable energy supplies is directly relevant to development, and to national and international security. As such, energy will continue to be an important part of the global agenda for the foreseeable future. Like many countries, Malaysia faces complex choices as it looks to expand its energy mix and ensure its energy security. At the IAEA, we stand ready to assist you in finding the solutions that are best suited to your needs and priorities

    A proper design outdoor environment in higher institutions contributes to the students’ learning performances and produce better learning outcomes. Campus surrounding has the potential to provide an informal outdoor learning environment, especially when it has the existing physical element, like open spaces and natural features, that may support the learning process. However, scholarly discourses on environmental aspects in tertiary education have minimal environmental inputs to fulfill students’ needs for outdoor exposure. Universities have always emphasized on traditional instructional methods in classroom settings, without concerning the importance of outdoor classroom towards students’ learning needs. Moreover, the inconvenience and discomfort outdoor surrounding in campus environment offers a minimal opportunity for students to study outside the classroom, and students eventually do not favor to utilize the spaces because no learning facility is provided. Hence, the objective of this study is to identify the appropriate criteria of outdoor areas that could be converted to be outdoor classrooms in tertiary institutions. This paper presents a review of scholars’ work in regards to the characteristics of the outdoor classrooms that could be designed as part of contemporary effective learning space, for the development of students’ learning performances. The information gathered from this study will become useful knowledge in promoting effective outdoor classroom and create successful outdoor learning space in landscape campus design. It I hoped that the finding of this study could provide guidelines on how outdoor classrooms should be designed to improve students’ academic achievement.

    The multiracial population in Malaysia has lived together for almost a century, however, the risk of gastric cancer among them varies. This study aimed to determine the distribution of different gastric adenocarcinoma subtypes and Helicobacter pylori infection status among gastric adenocarcinoma patients. Patients with gastric adenocarcinoma were enrolled from November 2013 to June 2015. Blood samples were collected for detection of H. pylori using ELISA method. Gastric adenocarcinoma cases were more prevalent in the Chinese (52.8%), followed by the Malays (41.7%) and least prevalent in the Indians (5.6%). Gastric adenocarcinoma located in the cardia was significantly more prevalent in the Malays (66.7%) compared to the Chinese (26.3%), whereas non-cardia cancer was diagnosed more in the Chinese (73.7%) compared to the Malays (33.3%) [P = 0.019; OR = 5.6, 95 CI: 1.27 to 24.64]. The Malays also had significantly higher prevalence of gastric tumour located at the cardia or fundus than other gastric sites compared to the Chinese (P = 0.002; OR: 11.2, 95% CI: 2.2 to 56.9). Among the cardia gastric cancer patients, 55.6% of the Malays showed intestinal histological subtype, whereas all the Chinese had the diffuse subtype. More than half of the patients (55.3%) with gastric adenocarcinoma were positive for H. pylori infection and among them, 66.7% were Chinese patients. The risk of gastric adenocarcinoma in our population is different among ethnicities. Further studies on host factors are needed as it might play an important role in gastric cancer susceptibility in our population.

    Sera from healthy donors and patients stored over a period of 2 years, aged 1 to 83 years, were examined for reactivity to human herpes virus 6 (HHV-6) by the standard indirect immunofluorescence assay (IFA). Of the 600 serum specimens screened, 502 showed positive reactivity to HHV-6. This gives an overall seropositive rate of 83.7%. There is no significant difference in the overall positive rate between the ethnic groups (Chinese, Malays, Indians) (chi 2 = 0.35 df = 2 p > 0.05). However, there is significant difference in the positive rates at the extreme age groups of 1 year as well as 61 years and above. From birth up to below 1 year of age, the seroprevalence rate was 82%. At one year of age the positive rate decreased to 66% before gradually rising so that the percentage seropositivity of 6 to 10 years old becomes similar to that in older children and adults (11 to 40 years). The positive rate then starts to decline after 40 years of age. Using a standardized scoring system, the corresponding antibody titer was found to be high in the very young population and starts to decline after the age of 15 years. This suggests that in our population group, primary infection occurs mainly in the pediatric age group. It also accounts for the low positive rate in the age group of 61 years and above, as by then the titer had fallen to the level below the detection limits of the assay system.

    Several modifiable risk factors for sudden infant death syndrome (SIDS) have been identified such as sleeping prone or on the side, sleeping on a soft surface, bed-sharing, no prenatal care and maternal ante-natal smoking. A cross-sectional survey of infant sleep and care practices was conducted among parents of babies aged below 8 months to determine the prevalence and predictors of non-supine sleep position and the prevalence of other high-risk infant care practices for SIDS. Of 263 infants, 24.7% were placed to sleep in the non-supine position and age of infants was a factor positively associated with this (adjusted odds ratio 1.275, 95% CI=1.085, 1.499). The most common modifiable risk factor was the presence of soft toys or bedding in the infants' bed or cot (89.4%). Results from this study indicate that although the predominant sleep position of Malaysian infants in this population is supine, the majority of infants were exposed to other care practices which have been shown to be associated with SIDS.

    Full Text Available BACKGROUND: Helicobacter pylori is the etiological agent for diseases ranging from chronic gastritis and peptic ulcer disease to gastric adenocarcinoma and primary gastric B-cell lymphoma. Emergence of resistance to antibiotics possesses a challenge to the effort to eradicate H. pylori using conventional antibiotic-based therapies. The molecular mechanisms that contribute to the resistance of these strains have yet to be identified and are important for understanding the evolutional pattern and selective pressure imposed by the environment. METHODS AND FINDINGS: H. pylori was isolated from 102 patients diagnosed with gastrointestinal diseases, who underwent endoscopy at University Malaya Medical Centre (UMMC. The isolates were tested for their susceptibility on eleven antibiotics using Etest. Based on susceptibility test, 32.3% of the isolates were found to have primary metronidazole resistance; followed by clarithromycin (6.8% and fluoroquinolones (6.8%. To further investigate the resistant strains, mutational patterns of gene rdxA, frxA, gyrA, gyrB, and 23S rRNA were studied. Consistent with the previous reports, metronidazole resistance was prevalent in the local population. However, clarithromycin, fluoroquinolone and multi-drug resistance were shown to be emerging. Molecular patterns correlated well with phenotypic data. Interestingly, multi-drug resistant (MDR strains were found to be associated with higher minimum inhibitory concentration (MIC than their single-drug resistant (SDR counterparts. Most importantly, clarithromycin-resistant strains were suggested to have a higher incidence for developing multi-drug resistance. CONCLUSION: Data from this study highlighted the urgency to monitor closely the prevalence of antibiotic resistance in the Malaysian population; especially that of clarithromycin and multi-drug resistance. Further study is needed to understand the molecular association between clarithromycin resistance and multi-drug resistance in H. pylori. The report serves a reminder that a strict antibiotic usage policy is needed in Malaysia and other developing countries (especially those where H. pylori prevalence remained high.

To further investigate the resistant strains, mutational patterns of gene rdxA, frxA, gyrA, gyrB, and 23S rRNA were studied. Consistent with the previous reports, metronidazole resistance was prevalent in the local population. However, clarithromycin, fluoroquinolone and multi-drug resistance were shown to be emerging. Molecular patterns correlated well with phenotypic data. Interestingly, multi-drug resistant (MDR) strains were found to be associated with higher minimum inhibitory concentration (MIC) than their single-drug resistant (SDR) counterparts. Most importantly, clarithromycin-resistant strains were suggested to have a higher incidence for developing multi-drug resistance. Data from this study highlighted the urgency to monitor closely the prevalence of antibiotic resistance in the Malaysian population; especially that of clarithromycin and multi-drug resistance. Further study is needed to understand the molecular association between clarithromycin resistance and multi-drug resistance in H. pylori. The report serves a reminder that a strict antibiotic usage policy is needed in Malaysia and other developing countries (especially those where H. pylori prevalence remained high).

    This study is to review the impact of climate change and land used on flooding through the SMART Project. It also simulate the Flood Forecasting in Klang River Basin in order to compare the changes in the existing river system in Klang River Basin with the Storm water Management and Road Tunnel (SMART) which is now already operating in the city center of Kuala Lumpur.The catchment area of the Klang River basin is 1,288 square kilometers (km2), and it is the most urbanized region in Malaysia, encompassing the Federal Territory of Kuala Lumpur and part of the state of Selangor. The basin spreads over nine local government authorities and faces serious environmental degradation and flooding problems from urbanization, industrialization, and population growth. More than half of the basin has been urbanized, and much of this continuing urban development has taken place on land that is prone to flooding. Flooding problem in Klang River Basin is still exist even measures and numerous flood mitigation projects and programs has been carried out by many parties. Even though that the new drainage guideline has been proposed since year 2000, flood reduction for Klang River basins is not successful enough. This problem contributed to the needs of this research to enhance the existing flood forecasting and mitigation project. This study analyzed and quantified the spatial patterns and time-variability of daily, monthly and yearly rainfall in Kuala Lumpur. An overview of rainfall patterns will be obtained through the analysis of 12 point data sources. Statistical properties of annual, monthly, and daily rainfall were derived. Spatial correlation fields for the annual and monthly rainfalls were studied.

Private general practitioners (GPs in Malaysia are granted rights under the Poison Act 1952 to prescribe and dispense medications at their primary care clinics. As most consumers obtain their medications from their GPs, community pharmacists’ involvement in ensuring safe use of medicines is limited. The integration of a pharmacist into private GP clinics has the potential to contribute to quality use of medicines. This study aims to explore health care consumers’ views on the integration of pharmacists within private GP clinics in Malaysia.Methods: A purposive sample of health care consumers in Selangor and Kuala Lumpur, Malaysia, were invited to participate in focus groups and semi-structured interviews. Sessions were audio recorded and transcribed verbatim and thematically analyzed using NVivo 10. Results: A total of 24 health care consumers participated in two focus groups and six semi-structured interviews. Four major themes were identified: 1 pharmacists’ role viewed mainly as supplying medications, 2 readiness to accept pharmacists in private GP clinics, 3 willingness to pay for pharmacy services, and 4 concerns about GPs’ resistance to pharmacist integration. Consumers felt that a pharmacist integrated into a private GP clinic could offer potential benefits such as to provide trustworthy

Methods: The mushroom was boiled in hot water to liberate the polysaccharides, the extract of which was then used directly for the reduction of graphene oxide. The abundance of polysaccharides present in the mushroom serves as a good reducing agent. The proposed strategy evades the use of harmful and expensive chemicals and avoids the typical tedious reaction methods. Results: More importantly, the mushroom extract can be easily separated from the product without generating any residual byproducts and can be reused at least three times with good conversion efficiency (75%. It was readily dispersible in water without the need of ultrasonication or any surfactants; whereas 5 minutes of ultrasonication with various solvents produced RGO which was stable for the tested period of 1 year. Based on electrochemical measurements, the followed method did not jeopardize RGO’s electrical conductivity. Moreover, the obtained RGO was

The apoptogenic effect of the ZER-NLC on Jurkat cells was determined by fluorescent and electron microscopy, Annexin V-fluorescein isothiocyanate, Tdt-mediated dUTP nick-end labeling assay, cell cycle analysis, and caspase activity. An MTT (3-(4,5-dimethylthiazol-2-yl-2,5 diphenyltetrazolium bromide assay showed that ZER-NLC did not have adverse effects on normal human peripheral blood mononuclear cells. ZER-NLC arrested the Jurkat cells at G2/M phase with inactivation of cyclin B1 protein. The study also showed that the antiproliferative effect of ZER-NLC on Jurkat cells is through the intrinsic apoptotic pathway via activation of caspase-3 and caspase-9, release of cytochrome c from the mitochondria into the cytosol, and subsequent cleavage of poly (adenosine diphosphate-ribose polymerase (PARP. These findings show that the ZER-NLC is a potentially useful treatment for acute lymphoblastic leukemia in humans.Keywords: zerumbone-loaded nanostructured lipid carrier, cell cycle arrest, apoptosis, mitochondrial pathway

    Fishing is one of the most important industries in Malaysia, providing the people with employment and supplying them with protein from the fish. Fish comprises about 80% of the protein intake of the population. In recent years industrialization and urbanization have encroached into many coastal fishing villages, which in many cases cause water pollution. As a result, the livelihood of small inshore fisherman have been threatened or destroyed. At the same time coastal fishes are contaminated by pollutants from industrial wastes especially the toxic heavy metals. The studies showed that the average mercury levels in commercial marine fishes marketed in Malaysia range from 0.08 - 0.046 mg/kg wet weight. It is apparent that fish is a possible source of mercury exposure to the general population in Malaysia. Per capita fish consumption in Malaysia is 100 g/d/person, and there are efforts by the Malaysian Government to increase fish consumption to 300 g/day/person. 7 refs, 1 tab

    Malaysia is one of the world's leading producers of rubber, palm oil and cocoa beans. There is a great concern within the commodity industries of the possible outbreak of plant diseases yet to be detected in the country but endemic in the South American tropics and Africa. The risk of transferring the diseases to Malaysia are high because of increasing contacts between Malaysia and the South American countries and Africa through trades, tourism and the South-South cooperation. Diseases of particular importance are the South American leaf blight (SALB) of rubber, vascular wilts of oil palm and witches'broom of cocoa caused by Microcyclus ulei, Fusarium oxysporum f sp. elaeidies and Crinipellis pemiciosa (Stahel) Singer respectively. Recent estimates by the Agriculture Department of Malaysia indicated in the event of large scale attack by SALB on rubber would result in revenue loss of a staggering RM 3-3.5 billion per annum, an equivalent of 70% loss in rubber acreage. This excludes massive unemployment in the rubber industry and cost of cleaning up activities to eradicate and free plantations of SALB. Recurring attacks of the diseases cannot be discounted given the fact that spores of fungi can remain dormant for years but still viable. Stringent control and quarantine steps are presently being exercised by the authorities to intercept at airports and hence prevent entry of infectious plant diseases in Malaysia. Many of the measures using chemicals, ultra violet light (UV), steam sterilization, air blowers etc. are not sufficiently effective in killing fungi especially when spores are carried in the personal belongings of air-passengers. There was suggestion that ionizing radiation offers alternative to the present methods for intercepting pathogens at the port of entry. This paper will firstly, discuss results on the investigations carried out to compare the effectiveness of various ionizing radiation sources, i.e., gamma, electron beam and x-rays; chemicals and UV to kill plant pathogens; and secondly, on the comparison of installing the different types of ionizing radiation facilities at the KLIA for treatment of baggage to intercept exotic plant pathogens

    To explore the barriers faced by healthcare professionals (HCPs) in managing falls among older people (aged above 60 years) who have a high risk of falling. The study used a qualitative methodology, comprising 10 in-depth interviews and two focus group discussions. A semistructured topic guide was used to facilitate the interviews, which were audio recorded, transcribed verbatim and checked for accuracy. Data were analysed thematically using WeftQDA software. 20 HCPs who managed falls in older people. This study was conducted at the Primary Care Clinic in the University Malaya Medical Centre (UMMC), Malaysia. Four categories of barriers emerged-these were related to perceived barriers for older people, HCPs' barriers, lack of caregiver support and healthcare system barriers. HCPs perceived that older people normalised falls, felt stigmatised, were fatalistic, as well as in denial regarding falls-related advice. HCPs themselves trivialised falls and lacked the skills to manage falls. Rehabilitation was impeded by premature decisions to admit older people to nursing homes. Lastly, there was a lack of healthcare providers as well as a dearth of fall education and training on fall prevention for HCPs. This study identified barriers that explain poor fall management in older people with a high risk of falls. The lack of structured fall prevention guidelines and insufficient training in fall management made HCPs unable to advise patients on how to prevent falls. The findings of this study warrant evidence-based structured fall prevention intervention targeted to patients as well as to HCPs. Published by the BMJ Publishing Group Limited.

    The most commonly used techniques of alpha and gamma spectrometry were compared to measure 210 Pb activity in marine sediment core. Alpha analytical technique measured the activity of 210 Pb from its in-grow grand-daughter 210 Po after a chemical separation by assuming that there is radioactive equilibrium between the two radionuclides. Meanwhile, gamma analysis technique allows direct measurement, non-destructive and no preliminary chemical separation. Through the comparison, it was found that both alpha and gamma analysis techniques were slightly different. Overall, the results from gamma analytical technique were higher than those from the alpha analytical techniques. Some logical argument had been discussed to explain this situation. In routine analysis, the analytical technique used should be chosen carefully based on advantages and disadvantages of the each technique and analysis requirements. Therefore, it is recommended to determine the exact needs and purpose of analysis and to know the sample history before deciding the appropriate analytical technique. (author)

    The Klang area of Peninsular Malaysia has experienced rapid industrial growth with intense activities, which can increase the concentration of pollutants in the environment that significantly impact on habitats and the human health. The purpose of this study was to determine the levels of selected heavy metals (Cu, Zn, Ni, Fe, and Pb) in the heart, lung, brain, liver, kidney, muscle tissues, and feathers of house crow, Corvus splendens, in Klang, Peninsular Malaysia. House crow samples were collected from the Klang area through the Department of Public Health at Majlis Perbandaran Klang. Quantitative determination of heavy metals was carried out using atomic absorption spectrophotometer (AAS). The result shows the presence of heavy metals in all biological samples of house crows. For heavy metals in all the house crow tissues analyzed, Fe concentrations were the highest, followed by those of Zn, Cu, Pb, and Ni. The feathers and kidney accumulated high concentrations of Pb, whereas the liver accumulated high concentrations of essential heavy metals (Fe > Zn > Cu > Ni). Significant variations were also detected in the concentrations of Pb among adult and juvenile and male and female bird samples. The results also revealed significant positive correlations between Pb metal concentration in the breast feathers and all internal organs. Accumulation of toxic heavy metals in feathers reflected storing and elimination processes, while the accumulation of toxic heavy metals in the kidney can be consequential to chronic exposure. The present study clearly shows the usefulness of house crow breast feather as a suitable indicator for heavy metal accumulation in the internal organs of house crows in the Klang area.

    To assess the knowledge and perceptions of Malaysian government dentists regarding the shortened dental arch (SDA) concept and its application in clinical practice. The SDA concept refers to a specific type of dentition with intact anterior teeth and a reduction in posterior occlusal pairs. Dentists' knowledge and perceptions of the SDA concept can influence its application in clinical practice. A self-administered questionnaire on the SDA concept was distributed to 326 government dentists in the states of Selangor and Kuala Lumpur, Malaysia. The data were analysed using SPSS version 22 software. The response rate was 84.0%. The majority of respondents had good knowledge on five of six knowledge items and good attitudes towards 10 of 17 perception items. However, only one-fifth (20.4%) reported having applied the SDA concept in the clinic. A larger number of participants who graduated locally than who graduated abroad perceived that patients age, without molar support, can attain acceptable chewing function and that SDA treatment does not lead to loss of occlusal vertical dimension (P 5 years of work experience perceived that the SDA concept enables simpler treatment planning (P concept, it is not widely applied in the clinic. Concerted efforts in SDA training of dentists are needed to help to shorten denture waiting lists and reduce costs. © 2017 FDI World Dental Federation.

    This study was a qualitative investigation into sexual attitudes and behaviours, and contraceptive use among Malaysian youth, based on constructs from the health belief model, theory of reasoned action, and problem behaviour theory. A total of 34 focus group discussions with 185 participants were conducted among the Malay (35%), Chinese (34%), and Indian (31%) young females between November, 2010 and April, 2011. The participants were secondary school students and university undergraduates from Selangor and the Federal Territory of Kuala Lumpur. The study found a lack of knowledge about sexual issues and contraception among the participants. Many engaged in unprotected sexual intercourse and relied on periodic abstinence, natural methods, and traditional folk pregnancy preventive practices. The findings also revealed numerous categories of factors influencing sexual attitudes and behaviours: ethnic group and religion, level of religiosity, peer pressure and norms, and parental monitoring. With regard to condom use, factors such as embarrassment about condom acquisition, low perceived susceptibility to sexually transmitted infections (STIs), and perceived efficacy of traditional and folk methods of contraception, were uncovered from the discussions. This study underscores the importance of development of culturally specific interventions that address the identified promoting factors of premarital sex. Behavioral interventions to promote condom use should increase awareness about condom effectiveness against not only unwanted pregnancies but also STIs.

    Dengue fever is a major public health problem in Malaysia. This study aimed to assess factors affecting knowledge, attitudes, and practices regarding dengue fever among a selected population in Malaysia. A descriptive, community-based, cross sectional study was conducted with 300 participants from three different geographical settings in urban, semi-urban, and rural areas within the states of Selangor and Kuala Lumpur. The questionnaire included questions on demographic data, knowledge, attitudes, and practices regarding dengue fever. Mean age of respondents was 34.4 (+/- 5.7) years, and the age ranged from 18 to 65 years. The majority of respondents were married (54.7%), Malays (72.7%) and heard about dengue fever (89.7%). Television was the common source of information about dengue fever (97.0%). Participants answered 4 out of 15 items of knowledge incorrectly. There was no significant association between knowledge score and socio-demographic factors. About one-fifth of the respondents (24%) believed that immediate treatment is not necessary for dengue fever, and the majority of them were not afraid of the disease (96.0%). Attitudes toward dengue fever were significantly associated with the level of education and employment status (p dengue fever (p = 0.030). There is a need to increase health promotion activities through campaigns and social mobilization to increase knowledge regarding dengue fever. This would help to mold positive attitudes and cultivate better preventive practices among the public to eliminate dengue in the country.

    Mangroves in Peninsular Malaysia are typical of tropical forest setting. Nevertheless, the state of the mangrove forests has led to various classifications; natural and degraded mangroves. The study aimed to utilize litter fall (production and standing crop) potential as a means of evaluating the degree of productivity of the mangrove types across seasons, in addition to determining the abundance of carbon and nitrogen in the Peninsular mangrove forest. Leaf litter accounted for more than 70% of the total litter production in both natural and degraded mangroves, and the peak month for such production was December; 82.7% and 82.2%, for Sungai Haji Dorani and Kuala Selangor Nature Park, respectively. The degraded mangrove recorded higher concentration of total N (6.16 mg/g) than the natural mangrove forest (5.60 mg/g) at significant level. However, the organic carbon (CO) content across the litter parts varied with the three seasons. The CO of leaf litter was at the peak during the dry season, however, analysis on the branch and fruit revealed that during the intermediate and wet seasons CO level could be higher than the concentration observed at dry season. Though, the study concluded that both mangrove types in Peninsular Malaysia showed high similarity in the degree of litter production, yet the identified differences suggest that counter measures need to be adopted in order to protect mangroves from degradation and possible productivity loss.

    Full Text Available Background: This study employs a field experiment to examine the relationship between professional skepticism, experience, and time budget pressure on auditors’ assessment of risk of misstatement. In addition, the study examines the moderating effect of experience and time budget pressure on the relationship between professional skepticism and auditors’ assessment of risk from material misstatements; 2 Method: This study employs a multiple regression analysis on 248 auditors from both Big4 and non-Big4 firms; 3 The results indicate that professional skepticism and experience have positive effects while time budget pressure has a negative effect on auditors’ assessment of risk from material misstatements; and 4 The positive effect of professional skepticism on auditors’ assessment of risk from material misstatement is stronger among more experienced auditors than that among less experienced. On the other hand, the positive effect of professional skepticism on risk assessment is weaker when auditors work under high time budget pressure than that when they work under low time budget pressure. Additional analysis on the samples from the two selected areas, Kuala Lumpur and Selangor, produces consistent results indicating that the use of separate models for different samples is not necessary. Hence, the study uses a single model for the final analysis. The results provide a better understanding on whether the auditors are able to sustain professional skepticism with a given amount of relevant audit experience and under different levels of time budget pressure.

    ADEGUN, I. K.

    2014-08-01

    Full Text Available The paper investigated the flow of incompressible fluid and contaminant transport through a Porous Landfill using a numerical technique. A threedimensional finite element analysis technique was adopted for the solution. The problem was based on the Darcy’s Law and the Advection-Dispersion equation. The solutions of the Darcy’s and Advection-Dispersion equations were generated using Finite Element Analysis Software known as COMSOL Multiphysics. This simulation tool tracked the contaminant transport in the Landfill for 360 days at 10 days interval. It first modeled steady-state fluid flow by employing the Darcy’s Law Application Mode and then followed up with a transient solute-transport simulation by employing the Solute-Transport Application Mode from the Earth Science Module of COMSOL. The solution results obtained from this model were found to be in close agreement with reallife data obtained at the 130- million ton Bukit Tagar Mega Sanitary Landfill site, Selangor near Kuala Lumpur, Malaysia. This showed that the model can effectively predict the trends in the distributions of pollutants from a Municipal Solid Waste Landfill into nearby land and water sources. The model is thus applicable to the issues of environmental protection and safety of groundwater.

    Full Text Available The delivery performance of the low cost housing is questioned since the occupants are prone towards safety hazards in the housing complex, such as structural instability and falling building fragments. Without defining the occupants’ requirements for the development of low cost housing, the prevailing safety factors are hard to be determined. This paper explores the rationale of safety performance assessment in the low cost housing by considering the occupants’ participation to achieve a better safety provision during occupancy period. Questionnaire survey was distributed to 380 occupants of the low cost housing in Kuala Lumpur and Selangor, Malaysia. The result shows that 80.8% of the respondents had expressed their dissatisfaction with the safety performance of the lift. By referring to the mode of ranking level, the most significant aspect rated by the respondents is Building Safety Features, with 51.6% respondents. The attained aspects can be fundamental parameters which can be considered in the future development of low cost housing.

    The study seeks to explore the perception of international patients on Malaysia as a medical tourism destination country, as well as overall patient satisfaction, perceived value and future intention for repeat treatment and services. Self-administered questionnaire was the main method of data collection. The survey covered major private hospitals in medical tourists' states in the country, namely, Penang, Melaka, Selangor and Kuala Lumpur. Convenience sampling was used due to the condition of patients as respondents. Indonesian patients formed the largest majority of international patients in the country. Five dimensions of medical tourism in Malaysia was identified, namely, hospital and staff, country factor, combining tourism and health services, cost saving and insurance and unavailability of treatment. Of these, hospital and staff was found to be the most important factor for the patients. Perception of value, overall satisfaction and intention for future treatment was also found to be high. This indicates that Malaysia is on the right footing in this burgeoning industry. Findings from the study will enable policy-makers to better position Malaysia as a medical tourist destination country. Medical tourism is a recent phenomenon and very little empirical research has been carried out at the patient level. This study is one of the first few studies which seek to explore medical tourism from the perspective of the patients themselves.

    The socioeconomic, social behaviour and dietary pattern of 100 Aborigines and Malays, aged 7 years and above from Kuala Pangsoon, Selangor Malaysia were studied by using pretested questionnaires. The individual's dietary intake was estimated using 24 hour recall for 3 days within one week which was chosen at random. The household's food consumption pattern was evaluated using food frequency questionnaires. There was no difference in the total income per month for both communities, as well as the educational attainment of the head of household and property ownership. The proportion of smokers among the Aborigines and the Malays was almost similar (33%) but the percentage of heavy smokers was higher among Aborigines compared to Malays. One third of the Aborigines regularly consume alcohol. The main energy source for both communities was rice, sugar and cooking oil whilst fish and eggs were the main sources of protein. More than 50% of the Aborigines take tapioca or tapioca leaves at least once a week compared to less than 20% among the Malays. There was no significant different in the intake of energy, protein and carbohydrate between the groups. However, the Aborigines take less fats and iron compared to the Malays. The difference in terms of smoking, drinking habit and dietary intake may determine the distribution of disease in both communities.

    The early development of mini hydro development in Peninsular Malaysia was carried out by the National Electricity Board (NEB) and the projects developed in the 50s and 60s were Ulu Langat (Selangor), Sempam, Kg. Raja , Kuala Terla, and Robinson Falls (all in Pahang). In the 70s the main effort of hydropower development was concentrated on developing major hydropower projects not only to cater to the country increasing demand for electricity but also to the country needs for flood control. This development was feverishly carried out on the Perak River and the prohects built were Temenggor (384 MW), Bersia (72 MW), Kenering (20 MW), Sg Piah (70 MW) and the Kenyir (400 MW) project in Sungai Terengganu. In late 1970s, the government was keen to electrify the rural areas of Peninsular Malaysia and mini hydro power development was thought of as an option to provide electricity to these areas. The Mini Hydro Department of National Electricity Board (MHD) was then formed to undertake the task of planning, developing and implementing mini hydro projects to meet this government aspiration.

    Full Text Available Effective communication within an organization as part of CSR benchmarking factor that helps align employee expectations facilitates problem solving, builds cooperative relationships and channels employee efforts to achieve common goals. This paper seeks to determine how CSR benchmarking factors of the organizational environment (such as management style, organizational structure and workplace culture affect the effectiveness of intra-organizational communication and to examine the moderating effect of supervisor – subordinate guanxi. Data for the study was collected using self-administered questionnaires from working respondents in Kuala Lumpur in Selangor State, Malaysia. This study found that a more participative management style, less formalized organizational structure of SMEs and a healthier workplace culture are positively related to intra-organizational communication effectiveness. It was also discovered that the supervisor – subordinate relationship known as guanxi, has a positive moderating effect on all three relationships between management style, organizational structure and workplace culture with intra-organizational communication effectiveness. This study concludes that an organization’s management attitude towards employee participation, formalization of structure and healthiness of culture play important roles in encouraging effective communication and close supervisor – subordinate guanxi and further promotes communication, in addition to the mentioned environmental conditions.

    Performance injuries among musicians have been widely discussed for decades. However, despite the growing number of classical pianists, this is still a new issue in Malaysia. Therefore, this study aimed to investigate the level of knowledge of playing-related musculoskeletal disorders (PRMDs) among tertiary music students in Malaysia. A survey was conducted among classical piano students at tertiary institutions of Kuala Lumpur and Selangor. Out of 192 respondents, 76% knew that piano playing can cause PRMDs. Slightly over three-quarters of respondents (77.1%) learned about PRMDs from music educators. The survey revealed that the belief in "no pain, no gain" was still ingrained in their minds, as 50.5% respondents believed that pain experienced while playing the piano was normal and 51.6% of them considered that pain must be experienced to improve their piano skill. The respondents were also scored on questions on terminologies of pianist injury and specific PRMD examples: 7.8% of respondents scored high in the questions on the general terminology, while 99.5% of them scored low in the questions on the specific examples of PRMDs. This finding indicated a lack of knowledge of specific musicians' injuries among classical piano students. The attitudes to pain and the level of understanding of the significance of potential injuries indicate that increasing PRMD awareness and introducing courses on PRMD prevention at tertiary institutions are warranted.

    Full Text Available This study was designed to empirically determine: (i to look the factors causes micro enterprises opt for using internal funding instead of external funding; and (ii to observe the probability of micro enterprises opt for Cash Waqf fund as alternative source of funding their business. The primary data is collected from the administered survey questions in Klang Valley (Selangor and Kuala Lumpur and the analysis is conducted using statistical analysis and Structural Equation Modeling (SEM. The model is validated its acceptance in the field by adopting the Theory of Reasoned Action (TRA. From the findings, among the factors that lead micro enterprises to use internal funding are strict collateral requirement by commercial financial institutions, high cost of financing, strict documentation requirement and good financial and business track record. Unfortunately, most of them cannot fulfill these conditions and continue to face the problem of accessing finance. The present study has developed the Cash Waqf Investment model to support micro enterprises to improve their access to finance and enhance the skills. Based on the responses received from the field, it has been shown that the intention and readiness of micro enterprises in accepting the model as a source of financial and human capital development services is impressive.

    The arrival of the British colony in Kuala Lumpur sparked a radical change in the town in terms of infrastructure and town planning. Due to the British Empire’s reign over Malaya in the advent of 20th century, the colonial architectural style has influenced a lot of important building in the royal town of Selangor. Some of the building is abandoned disrespect, disregard and it’s frightening. Many deemed historic buildings and structures disappears in exchange for modernity, which is a threat to the townscape and history. The local council of Klang aims to preserve clusters of colonial sights, place of worships, schools, and remnants of a fort that has shaped the town enabling people to be more appreciative towards it. Located in the heart of Klang town, the fire station sits next to another heritage trail icon, Raja Abdullah Warehouse. Without proper documentation and curation, the building significant will remain unknown and eventually disappear. The core of this paper will showcase the building design quality and its importance, as the first attempt to document the Balai Bomba Klang Selatan to assist in conserving its tangible and intangible qualities. The study aims to collate and document the tangible qualities of the fire station to complement the measured drawing exercise.

    1984-09-01

    Using ELISA and COPT diagnostic tests, serological evidence of Malaysian schistosomiasis was discovered among Orang Asli populations from three areas in Peninsular Malaysia. Serum samples collected in 1975 indicated an ELISA-positive prevalence of 25% and a COPT prevalence of 11% from Pos Iskandar, Pahang and an ELISA prevalence of 13% and a COPT of 4% from Bukit Lanjan, Selangor. Resurveys at these site in 1982-1984 showed a continued presence of serological positive individuals but prevalence rates were markedly lower: 7% and 1% for ELISA and 4% and 2% for COPT at Pos Iskandar and Bukit Lanjan respectively. Snail hosts were not found at either site. The source of infection for persons living in these lowland areas remains unknown. In a third area, Kuala Tahan, Pahang, located in the foothills of the central mountain range, foci of transmission have been found near to Orang Asli settlements. The serological prevalence rate among Negrito Orang Asli in that study area was 9% for ELISA and 4% for COPT. Thirty-three of 36 COPT-positive sera produced vacuolated bleb precipates and in 31 these were the only reactions seen. The high percentage of positives producing only these precipates suggests that among Orang Asli schistosomiasis patients such reactions are not an indication of recently acquired infection as has been reported for schistosomiasis patients in the Philippines.

    Full Text Available BACKGROUND: This study was a qualitative investigation into sexual attitudes and behaviours, and contraceptive use among Malaysian youth, based on constructs from the health belief model, theory of reasoned action, and problem behaviour theory. METHODS: A total of 34 focus group discussions with 185 participants were conducted among the Malay (35%, Chinese (34%, and Indian (31% young females between November, 2010 and April, 2011. The participants were secondary school students and university undergraduates from Selangor and the Federal Territory of Kuala Lumpur. RESULTS: The study found a lack of knowledge about sexual issues and contraception among the participants. Many engaged in unprotected sexual intercourse and relied on periodic abstinence, natural methods, and traditional folk pregnancy preventive practices. The findings also revealed numerous categories of factors influencing sexual attitudes and behaviours: ethnic group and religion, level of religiosity, peer pressure and norms, and parental monitoring. With regard to condom use, factors such as embarrassment about condom acquisition, low perceived susceptibility to sexually transmitted infections (STIs, and perceived efficacy of traditional and folk methods of contraception, were uncovered from the discussions. CONCLUSION: This study underscores the importance of development of culturally specific interventions that address the identified promoting factors of premarital sex. Behavioral interventions to promote condom use should increase awareness about condom effectiveness against not only unwanted pregnancies but also STIs.

    This study was conducted to measure the prevalence of cigarette smoking and to determine the individual, family, and environmental factors associated with smoking among young urban women. A cross-sectional study through self-administered questionnaire was conducted on female students enrolled in private higher learning institutions in Kuala Lumpur and Selangor, Malaysia, between July and October 2005. Analysis on 408 respondents showed that current smoker prevalence rate was 18.6%. Adjusted analyses showed significant association between smoking and individual factors, which are the importance of slim image, average monthly allowance, and car ownership. For family factors, analyses showed significant association between smoking and parental marital status and smoking status of male siblings. Strong associations were seen between female smoking and environmental factors, such as having more smoker friends, having smokers as best friends, keeping cigarette-brand items, being offered free cigarette, and perceiving female smoking as normal. The identified risk factors could be used to develop more effective prevention programs to overcome smoking among young urban women.

    Full Text Available In recent years, there have been increasing accounts of illegal substance abuse among university students and professional groups in Malaysia. This study looks at university students’ perceptions about this phenomenon. Students from Malaysian universities were asked for their impressions about drug availability and abuse, as well as factors contributing to drug abuse and relapse. The questionnaire also inquired into their knowledge and views regarding government versus private rehabilitation centres, as well as their exposure to, and views about, school-based drug-prevention education. Participants were 460 university students from five Malaysian states: Penang, Selangor, Kuala Lumpur, Sabah, and Sarawak. Results showed gender differences in perceptions of relapse prevention strategies, as well as factors leading to drug abuse and relapse. Students also believed that drug education would be more effective if initiated between the ages of 11 to 12 years, which is slightly older than the common age of first exposure, and provided suggestions for improving existing programs. Implications of student perceptions for the improvement of current interventions and educational programs are discussed.

  5. Emergence of chikungunya seropositivity in healthy Malaysian adults residing in outbreak-free locations: Chikungunya seroprevalence results from the Malaysian Cohort

    2013-01-01

    Background In 1998, Malaysia experienced its first chikungunya virus (CHIKV) outbreak in the suburban areas followed by another two in 2006 (rural areas) and 2008 (urban areas), respectively. Nevertheless, there is still a lack of documented data regarding the magnitude of CHIKV exposure in the Malaysian population. The aim of this study was to determine the extent of chikungunya virus infection in healthy Malaysian adults residing in outbreak-free locations. Methods A cross sectional study of chikungunya (CHIK) seroprevalence was carried out in 2009 amongst The Malaysian Cohort participants living in four states (Kuala Lumpur, Selangor, Pahang and Negeri Sembilan). A total of 945 participants were randomly identified for the study. Potential risk factors for CHIK infection were determined via questionnaires, and IgG antibodies against CHIK were detected by an enzyme-linked immunosorbent assay. Logistic regression identified risk factors associated with CHIK seropositivity, while geographical information system was used for visual and spatial analysis. Results From the 945 serum samples tested, 5.9% was positive for CHIK IgG. Being male, Malay, rural occupancy and Negeri Sembilan residency were identified as univariate predictors for CHIK seropositivity, while multivariate analysis identified being male and rural occupancy as risk factors. Conclusions This study provided evidence that CHIK is slowly emerging in Malaysia. Although the current baseline seroprevalence is low in this country, increasing number of CHIK cases reported to the Malaysia Ministry of Health imply the possibility of CHIK virus becoming endemic in Malaysia.

    The prevalence of hypertension in Malaysia is increasing and an effective management of hypertension is important to reduce cardiovascular morbidity and mortality. To determine the knowledge, awareness and perception towards hypertension among residents in nursing homes as well as the roles of caregivers in hypertension management. A face-to-face survey with 200 hypertensive residents and 30 caregivers from 24 nursing homes in Kuala Lumpur and Selangor, Malaysia was conducted. Of all the hypertensive residents, 90.5% ( n = 181) knew that lowering their blood pressure could improve their health. Most residents strongly believed that taking antihypertensive drugs is important for keeping their high blood pressure under control ( n = 162, 81%). Taking medication was perceived as the most important factor in controlling the high blood pressure (58%, n = 116) compared to lifestyle or diet modification. The majority of the caregivers reported that they played a major role in managing hypertension, especially with regards to medication-taking. task (66.7%, n = 20). The knowledge, attitude and perceptions of hypertension play a relatively major role in the self-management of hypertension. The role of caregivers also needed to be recognised in managing hypertension in nursing homes.

    A qualitative comparative case study was conducted to compare and contrast food taboos and avoidance practices during pregnancy among Orang Asli or indigenous Temiar women in four distinct locations that represent different lifestyle experiences and cultural practices. Through snowballing sampling, a total of 38 participants took part in five focus groups: one group each in Pos Simpor and Pos Tohoi in Kelantan state, one group in Batu 12, Gombak in Selangor state, and two groups in a regroupment scheme (RPSOA) in Kuala Betis, Kelantan. All the transcripts were coded, categorised and 'thematised' using the software package for handling qualitative data, NVivo 8. Variant food prohibitions were recorded among the Temiar women residing in different locations, which differ in food sources and ways of obtaining food. Consumption of seventeen types of food items was prohibited for a pregnant Temiar woman and her husband during the prenatal period. Fear of difficulties during labour and delivery, convulsions or sawan, harming the baby (such as foetal malformation), and twin pregnancy seemed to trigger many food proscriptions for the pregnant Temiar women, most of which have been passed on from generation to generation. The findings of this study confirm that beliefs about food restrictions are strong among those Temiar living a traditional lifestyle. However, those who have adopted a more modern lifestyle also preserve them to some extent.

It can also be synthesized chemically to increase the yield. This compound is a promising candidate as a biological agent, as it is reported to be involved in a wide range of biological activities. Furthermore, FKB was reported to have antitumorigenic effects in several cancer cell lines in vitro. However, the in vivo antitumor effects of FKB have not been reported on yet. Breast cancer is one of the major causes of cancer-related deaths in the world today. Any potential treatment should not only impede the growth of the tumor, but also modulate the immune system efficiently and inhibit the formation of secondary tumors. As presented in our study, FKB induced apoptosis in 4T1 tumors in vivo, as evidenced by the terminal deoxynucleotidyl transferase dUTP nick end labeling and hematoxylin and eosin staining of the tumor. FKB also regulated the immune system by increasing both helper and cytolytic T-cell and natural killer cell populations. In addition, FKB also enhanced the levels of interleukin 2 and interferon gamma but suppressed interleukin 1B. Apart from that, FKB was also found to inhibit

Liposomes have been shown to improve the therapeutic efficacy of encapsulated drugs. The present study was conducted to compare the antinociceptive properties between liposome-encapsulated and free-form diclofenac in vivo via different nociceptive assay models. Liposome-encapsulated diclofenac was prepared using the commercialized proliposome method. Antinociceptive effects of liposome-encapsulated and free-form diclofenac were evaluated using formalin test, acetic acid-induced abdominal writhing test, Randall–Selitto paw pressure test, and plantar test. The results of the writhing test showed a significant reduction of abdominal constriction in all treatment groups in a dose-dependent manner. The 20 mg/kg liposome-encapsulated diclofenac demonstrated the highest antinociceptive effect at 78.97% compared with 55.89% in the free-form group at equivalent dosage. Both liposome-encapsulated and free-form diclofenac produced significant results in the late phase of formalin assay at a dose of 20 mg/kg, with antinociception percentages of 78.84% and 60.71%, respectively. Significant results of antinociception were also observed in both hyperalgesia assays. For Randall–Sellito assay, the highest antinociception effect of 71.38% was achieved with 20 mg/kg liposome-encapsulated diclofenac, while the lowest antinociceptive effect of 17.32% was recorded with 0 mg/kg liposome formulation, whereas in the plantar test, the highest antinociceptive effect

    Faid Rahman

    Full Text Available The Milky stork is listed as an endangered species endemic to the Southeast Asia region. In Malaysia, the population is currently being reintroduced back into the wild. However, the increase of anthropogenic activity throughout the coastal area might expose the population to hazardous chemicals such as heavy metals. This study highlights the contamination of cadmium (Cd and lead (Pb in the Milky stork’s diet. Additionally, this is the first time an integrated exposure model being used to assess heavy metal exposure risk to the population. Lead level (5.5–7.98 mg kg−1 in particular was relatively high compared to Cd (0.08–0.33 mg kg−1. This was probably related to the different niches occupied by the species in the aquatic environment. The results further show that the predicted exposure doses (through intake of both food and water for all metals are much lower than the Tolerable Daily Intake (TDI values. The total exposure dose for Cd was 0.11 mg kg−1 d−1 with TDI value of 0.54 mg kg−1 d−1 while Pb total exposure dose was 0.31 mg kg−1 d−1 with TDI value of 0.64 mg kg−1 d−1. Several possible factors that could lead to the observed pattern were discussed. In conclusion, there is an urgent need to improve the current habitat quality to protect the endangered species. The authors also emphasized on the protection of remaining Milky stork’s habitats i.e. mudflats and mangroves and the creation of buffer zone to mitigate the negative impacts that may arise from pollution activity.

    Full Text Available The functional relationships between flow (veh/km, density (veh/h and speed (km/h in traffic congestion have a long history of research. However, their findings and techniques persist to be relevant to this day. The analysis is pertinent, particularly in finding the best fit for the three major highways in Malaysia, namely the KL-Karak Highway, KL-Seremban Highway and KL-Ipoh Highway. The trans-logarithm function of density–speed model was compared to the classical models of Greenshields, Greenberg, Underwood and Drake et al. using data provided by the Transport Statistics Malaysia 2014. The results of regression analysis revealed that the Greenshields and Greenberg models were statistically significant. The trans-logarithm function was also tested and the results were nonetheless without exception. Its usefulness in addition to statistical significance related to the derived economic concepts of maximum speed and the related number of vehicles, flow and density and the limits of free speed were relevant in comparing the individual levels of traffic congestion between highways. For instance, KL-Karak Highway was least congested compared to KL-Seremban Highway and KL-Ipoh Highway. Their maximum speeds, based on three lanes carriage capacity of one direction, were 33.4 km/h for KL-Karak, 15.9 km/h for KL-Seremban, and 21.1 km/h for KL-Ipoh. Their corresponding flows were approximated at 1080.9 veh/h, 1555.4 veh/h, and 1436.6 veh/h.

    Measurement of quality of life among prostate cancer patients helps the health care providers to understand the impact of the disease in the patients' own perspective. The main aim of this study is to measure the quality of life among prostate cancer patients at University Malaya Medical Center (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and to ascertain the association factors for physical coefficient summary (PCS) and mental coefficient summary (MCS). A hospital based, cross sectional study using the Short Form-36 (SF-36) questionnaire was conducted over a period of 6 months. A total of 193 respondents were recruited. Their total quality of life score was 70.1± 14.7 and the PCS score was lower compared to MCS. The factors associated for PCS were: age, living partner, renal problem, urinary problem of intermittency, dysuria and hematuria. Factors associated for MCS were: age, living partner, renal problem, presenting prostatic specific antigen and urinary problem of intermittency and dysuria. Our prostate cancer patients had moderate quality of life in the physical health components but their mental health was less affected.

    Airborne particulates have been recognized as a crucial pollutant of indoor air. These pollutants can contribute towards poor indoor air quality (IAQ), which may affect human health in immediate or long term. This study aims to determine the level of IAQ and the effects of particulate towards occupants of office buildings (the office buildings selected for the case study are SSM, KTMB and MRCB at KL Sentral). The objectives of study are (i) to measure the level of airborne particulates that contribute to the IAQ during working hours, (ii) to compare the level of airborne particulates with the existing guidelines and standards of IAQ in Malaysia and other Asian countries and (iii) to assess the symptoms associated with airborne particulates among the building occupants, which were achieved through primary data collection (case study or site survey, structured interview and questionnaire survey) and supported by literature reviews. The results showed that the mass concentration level of airborne particulates within the areas has exceeded the allowable limit of 0.15mg/m3 by IAQ Code of Practice, 2005 of the Department of Safety and Health (DOSH), Malaysia and 0.05mg/m3 by the Department of Environmental (DOE) (outdoor) of 8 hours continuous sampling. Based on the findings, the highest mass concentration values measured is 2.581 mg/m3 at lobby of SSM building which is the highest recorded 17 times higher from the maximum limit recommended by DOSH than the others. This is due to the nearby construction works and the high numbers of particulates are generated from various types of vehicles for transportation surrounding KL Sentral. Therefore, the development of Malaysian Ambient Air Quality Guidelines on PM2.5 as one of the crucial parameters is highly recommended.

    Full Text Available Generally, quality of life of urban population is heavily dependent on social facilities provided within the environment. One of the most important facilities is transportations. Study on transportation mode in an urban area is especially very important because for almost every individual living in a large and densely populated area, mobility is one of the most crucial issues in everyday life. Enhance mobility, faster journey to work and less pollution from petrol-propelled vehicles can increase the quality of life, which in turn lead to a sustainable urban living. The study present transportation mode usage issues faced by community related to quality of life in an urban area. This study identifies several issues of transportation mode in urban areas and its impact on the quality of life. The study areas are Putrajaya, Kuala Lumpur and Bandar Kajang, Selangor. The methodology used in this research is secondary and primary data. The questionnaires for the survey were distributed from May 2008 to Jun 2008. These researches were conducted on 144 respondents for to evaluate their perception of transportation mode correlated to the quality of life. The collected data were then analyzed using “Statistical Packages for the Social Science” (SPSS. The respondents comprise of 61 males and 84 females from the age group of 18 to 57 years. This study identifies the percentage of public transportation mode usage in urban area, such as buses (16.7%, train (ERL, monorail and commuter-6.4%; which is very low compared to owning personal car (45.8% and motorcycle (25.4%.The result shows owning personal car is the highest (45.8% in three study areas and monorail and taxi are the lowest (1.4%.

Protein supplementation could improve the physical fitness by increasing protein anabolism, and exercise has a documented evidence of positive effect on functional status among the elderly. However, the combined effect of both protein supplementation and exercise has not been investigated among sarcopenic elderly in the Asian population. Thus, this study aimed to determine the effectiveness of exercise intervention and protein supplementation either alone or in combination for 12 weeks, on body composition, functional fitness, and oxidative stress among elderly Malays with sarcopenia. Sixty five sarcopenic elderly Malays aged 60-74 years were assigned to the control group, exercise group (ExG, protein supplementation group (PrG, or the combination of exercise and protein supplementation group. A significant interaction effect between body weight and body mass index (BMI was observed, with the PrG (-2.1% body weight, -1.8% BMI showing the highest reductions. Further, there was a decrease in % body fat (-4.5% and an increase in fat-free mass (kg (+5.7% in the ExG after 12 weeks (P < 0.05.

Although there have been studies on the influence of social support on medication adherence, these studies were conducted in Western settings, not in Asian settings where cultural and religious orientations may be different. The objective of this study was to assess the effects of cultural orientation and religiosity on social support and its relation to patients’ medication adherence. Methods: This was a cross-sectional study of patients with chronic diseases in two tertiary hospitals in Selangor, Malaysia. Patients who agreed to participate in the study were asked to answer questions in the following areas: 1 perceived group and higher authority cultural orientations; 2 religiosity: organizational and non-organizational religious activities, and intrinsic religiosity; 3 perceived social support; and 4 self-reported medication adherence. Patients’ medication adherence was modeled using multiple logistic regressions, and only variables with a P-value of <0.25 were included in the analysis. Results: A total of 300 patients completed the questionnaire, with the exception of 40 participants who did not complete the cultural orientation question. The mean age of the patients was 57.6±13.5. Group cultural orientation, organizational religious activity, non-organizational religious activity, and intrinsic religiosity demonstrated significant associations with patients’ perceived social support (r=0.181, P=0.003; r=0.230, P<0.001; r=0.135, P=0.019; and r=0.156, P=0.007, respectively.

    Full Text Available Reactive oxygen species and other radicals potentially cause oxidative damage to proteins, lipids, and DNA which may ultimately lead to various complications including mutations, carcinogenesis, neurodegeneration, cardiovascular disease, aging, and inflammatory disease. Recent reports demonstrate that Streptomyces bacteria produce metabolites with potent antioxidant activity that may be developed into therapeutic drugs to combat oxidative stress. This study shows that Streptomyces sp. MUM212 which was isolated from mangrove soil in Kuala Selangor, Malaysia, could be a potential source of antioxidants. Strain MUM212 was characterized and determined as belonging to the genus Streptomyces using 16S rRNA gene phylogenetic analysis. The MUM212 extract demonstrated significant antioxidant activity through DPPH, ABTS and superoxide radical scavenging assays and also metal-chelating activity of 22.03 ± 3.01%, 61.52 ± 3.13%, 37.47 ± 1.79%, and 41.98 ± 0.73% at 4 mg/mL, respectively. Moreover, MUM212 extract was demonstrated to inhibit lipid peroxidation up to 16.72 ± 2.64% at 4 mg/mL and restore survival of Vero cells from H2O2-induced oxidative damages. The antioxidant activities from the MUM212 extract correlated well with its total phenolic contents; and this in turn was in keeping with the gas chromatography–mass spectrometry analysis which revealed the presence of phenolic compounds that could be responsible for the antioxidant properties of the extract. Other chemical constituents detected included hydrocarbons, alcohols and cyclic dipeptides which may have contributed to the overall antioxidant capacity of MUM212 extract. As a whole, strain MUM212 seems to have potential as a promising source of novel molecules for future development of antioxidative therapeutic agents against oxidative stress-related diseases.

    Optimal nutrition is essential for healthy growth during adolescence. This study aims to investigate the baseline nutritional intake of Malaysian adolescents by gender, body mass index, and places of residence, both urban and rural. A cohort study was conducted consisting of 794 adolescents (aged 13-years) attending 15 public secondary schools from the Central (Kuala Lumpur and Selangor) and Northern (Perak) Regions of Peninsular Malaysia. Qualified dietitians conducted a 7-day historical assessment of habitual food intakes. Facilitated by flipcharts and household measurement tools, detailed information on portion sizes and meal contents were recorded. Nutritionist Pro™ Diet Analysis software was also used to analyze the dietary records.The mean age of the adolescents was 12.86 ± 0.33 y; the mean energy intake was 1659.0 ± 329.6 kcal/d. Males had significantly (P < .001) higher energy intake than females (1774.0 ± 369.8 vs 1595.2 ± 320.6 kcal/d); adolescents in rural schools consumed more energy and cholesterol (P < .001) compared to adolescents in urban schools (1706.1 ± 377.7 kcal/d and 244.1 ± 100.2 mg/d, respectively). Obese adolescents in rural schools consumed more energy and sugar (1987.6 ± 374.0 kcal/d and 48.9 ± 23.0 g/d) (p-value <0.001).The dietary intake of normal weight versus obese adolescents differs by the location of their school. Thus, the implementation of a structured and tailored intervention is recommended to help minimize this nutritional inequality.

    The food choices in childhood have high a probability of being carried through into their adulthood life, which then contributes to the risk of many non-communicable diseases. Therefore, there is a need to gather some information about children's views on foods which may influence their food choices for planning a related dietary intervention or programme. This paper aimed to explore the views of children on foods and the types of foods which are usually consumed by children under four food groups (snacks, fast foods, cereals and cereal products; and milk and dairy products) by using focus group discussions. A total of 33 school children aged 7-9 years old from Selangor and Kuala Lumpur participated in the focus groups. Focus groups were audio-taped, transcribed and analyzed according to the listed themes. The outcomes show that the children usually consumed snacks such as white bread with spread or as a sandwich, local cakes, fruits such as papaya, mango and watermelon, biscuits or cookies, tea, chocolate drink and instant noodles. Their choices of fast foods included pizza, burgers, French fries and fried chicken. For cereal products, they usually consumed rice, bread and ready-to-eat cereals. Finally, their choices of dairy products included milk, cheese and yogurt. The reasons for the food liking were taste, nutritional value and the characteristics of food. The outcome of this study may provide additional information on the food choices among Malaysian children, especially in urban areas with regard to the food groups which have shown to have a relationship with the risk of childhood obesity.

    Full Text Available The number of dengue cases has been increasing on a global level in recent years, and particularly so in Malaysia, yet little is known about the effects of weather for identifying the short-term risk of dengue for the population. The aim of this paper is to estimate the weather effects on dengue disease accounting for non-linear temporal effects in Selangor, Kuala Lumpur and Putrajaya, Malaysia, from 2008 to 2010. We selected the weather parameters with a Poisson generalized additive model, and then assessed the effects of minimum temperature, bi-weekly accumulated rainfall and wind speed on dengue cases using a distributed non-linear lag model while adjusting for trend, day-of-week and week of the year. We found that the relative risk of dengue cases is positively associated with increased minimum temperature at a cumulative percentage change of 11.92% (95% CI: 4.41–32.19, from 25.4 °C to 26.5 °C, with the highest effect delayed by 51 days. Increasing bi-weekly accumulated rainfall had a positively strong effect on dengue cases at a cumulative percentage change of 21.45% (95% CI: 8.96, 51.37, from 215 mm to 302 mm, with the highest effect delayed by 26–28 days. The wind speed is negatively associated with dengue cases. The estimated lagged effects can be adapted in the dengue early warning system to assist in vector control and prevention plan.

    Cigarette smokers have their own motivation and justification to smoke. For example, smoking reduces their stress or enhances their pleasure. This study aimed to identify the (a) prevalence of cigarette smokers among undergraduates in Malaysia, (b) gender differences in nicotine dependence among current smokers, (c) differences in psychological problems (depression, anxiety and stress) based on the status of smoking cigarettes (current, former and non-smokers) and (d) extent to which precipitating factors (tension reduction, addiction, automatism, handling, social interaction, pleasure, and stimulation) predict the smoking behavior among current smokers. In this study 780 undergraduate students participated from a private university in Kuala Lumpur and Selangor state in Malaysia. The Depression, Stress and Anxiety Scale, Modified Reason for Smoking Scale and Fagerstrom Nicotine Dependence Test were used to measure psychological problems, predictors of smoking behavior and nicotine dependency among current smokers. The results showed that 14.7%(n=106) of the students were smokers. Current smokers exhibited more psychological problems (depression, anxiety and stress) compared to former and non-smokers. Addiction, tension reduction, pleasure and automatism were predictors of smoking behavior among the current smoking students. Step wise regression analysis showed that smoking behavior was highly predicted by nicotine dependency or addiction. Smoking students were motivated to smoke cigarettes as they believed that it reduced their tension and enhance pleasure. Hence, there is a need for health promotion and anti-tobacco prevention as cigarette smokers experience more psychological problems. Nicotine dependency or addition was one of the major causes for smoking behavior among the student population in Malaysia.

    The sewerage and maintenance process of manhole is important to ensure that the underground pipelines and other systems are in good condition. The manhole is covered with manhole cover to prevent people, animals or any objects fall into it. The manhole cover has one pocket which is to lock it and ensure that nobody open it. A questionnaire survey is distributed to the workers at Indah Water Konsortium Sdn Bhd, Kuala Lumpur and interviews are conducted with Indah Water Konsortium (IWK) and Jabatan Perkhidmatan Pembentungan (JPP), Selangor to access the user requirements and needs for an effective manhole cover lifter. Currently, the workers used a T-hook to unlock the heavy manhole cover and lift it. However, this method affected some of the workers because they experienced back, legs, shoulders and arm injuries. The T-hook is also quite heavy and it is difficult to bring anywhere. Based on the result of questionnaire survey, four concepts are designed to create new manhole cover lifter with automated operation. The best concept is finalized by using concept screening and scoring method. The chosen concept is applied pulley chain mechanism and it is selected as the best concept because it is easy and safe to use, low cost maintenance, low time consuming and affordable price. The design of the device is suitable for Malaysian male and secured them from musculoskeletal disorder. The worker's posture is analyzed by using Rapid Upper Limb Analysis (RULA) ergonomics analysis. The stability and strength of the device is analyzed by calculation and Finite Element Analysis (FEA) is used to analyze the screw cylinder.

    The study on Clustering of Lifestyle risk factors and Understanding its association with Stress on health and wellbeing among school Teachers in Malaysia (CLUSTer) is a prospective cohort study which aims to extensively study teachers in Malaysia with respect to clustering of lifestyle risk factors and stress, and subsequently, to follow-up the population for important health outcomes. This study is being conducted in six states within Peninsular Malaysia. From each state, schools from each district are randomly selected and invited to participate in the study. Once the schools agree to participate, all teachers who fulfilled the inclusion criteria are invited to participate. Data collection includes a questionnaire survey and health assessment. Information collected in the questionnaire includes socio-demographic characteristics, participants' medical history and family history of chronic diseases, teaching characteristics and burden, questions on smoking, alcohol consumption and physical activities (IPAQ); a food frequency questionnaire, the job content questionnaire (JCQ); depression, anxiety and stress scale (DASS21); health related quality of life (SF12-V2); Voice Handicap Index 10 on voice disorder, questions on chronic pain, sleep duration and obstetric history for female participants. Following blood drawn for predefined clinical tests, additional blood and urine specimens are collected and stored for future analysis. Active follow up of exposure and health outcomes will be carried out every two years via telephone or face to face contact. Data collection started in March 2013 and as of the end of March 2014 has been completed for four states: Kuala Lumpur, Selangor, Melaka and Penang. Approximately 6580 participants have been recruited. The first round of data collection and blood sampling is expected to be completed by the end of 2014 with an expected 10,000 participants recruited. Our study will provide a good basis for exploring the clustering of

Patients and methods: A qualitative methodology was applied. The data were gathered from in-depth interviews with 25 hypertensive patients attending follow-up in nine government primary health clinics in two districts (Hulu Langat and Klang in the state of Selangor, Malaysia. The transcribed data were analyzed using thematic analysis.Results: There was evidence of lack of patient self-empowerment and community support in Malaysian society. Most of the participants did not take their antihypertensive medication or change their physical activity and diet after diagnosis. There was an agreement between the patients and the health care professionals before starting the treatment recommendation, but there lacked further counseling and monitoring. Most of the reasons given for not taking antihypertensive medication, not doing physical activity and not following diet recommendations were due to side effects or fear of the side effects of antihypertensive medication, patients’ attitudes, lack of information from health care professionals and insufficient social support from their surrounding environment. We also observed the differences on these reasons for nonadherence among the three ethnic groups.Conclusion: Health care professionals should move toward supporting adherence in the management of hypertensive patients by maintaining a dialogue. Patients need to be given time to enable them to overcome their

    Full Text Available Spatio-temporal patterns of dengue risk in Malaysia were studied both at the address and the sub-district level in the province of Selangor and the Federal Territory of Kuala Lumpur. We geocoded laboratory-confirmed dengue cases from the years 2008 to 2010 at the address level and further aggregated the cases in proportion to the population at risk at the sub-district level. Kulldorff’s spatial scan statistic was applied for the investigation that identified changing spatial patterns of dengue cases at both levels. At the address level, spatio-temporal clusters of dengue cases were concentrated at the central and south-eastern part of the study area in the early part of the years studied. Analyses at the sub-district level revealed a consistent spatial clustering of a high number of cases proportional to the population at risk. Linking both levels assisted in the identification of differences and confirmed the presence of areas at high risk for dengue infection. Our results suggest that the observed dengue cases had both a spatial and a temporal epidemiological component, which needs to be acknowl- edged and addressed to develop efficient control measures, including spatially explicit vector control. Our findings highlight the importance of detailed geographical analysis of disease cases in heterogeneous environments with a focus on clustered populations at different spatial and temporal scales. We conclude that bringing together information on the spatio-temporal distribution of dengue cases with a deeper insight of linkages between dengue risk, climate factors and land use constitutes an important step towards the development of an effective risk management strategy.

    Since the discovery of HIV-1 circulating recombinant form (CRF) 33_01B in Malaysia in the early 2000 s, continuous genetic diversification and active recombination involving CRF33_01B and other circulating genotypes in the region including CRF01_AE and subtype B′ of Thai origin, have led to the emergence of novel CRFs and unique recombinant forms. The history and magnitude of CRF33_01B transmission among various risk groups including people who inject drugs (PWID) however have not been investigated despite the high epidemiological impact of CRF33_01B in the region. We update the most recent molecular epidemiology of HIV-1 among PWIDs recruited in Malaysia between 2010 and 2011 by population sequencing and phylogenetic analysis of 128 gag-pol sequences. HIV-1 CRF33_01B was circulating among 71% of PWIDs whilst a lower prevalence of other previously dominant HIV-1 genotypes [subtype B′ (11%) and CRF01_AE (5%)] and CRF01_AE/B′ unique recombinants (13%) were detected, indicating a significant shift in genotype replacement in this population. Three clusters of CRF01_AE/B′ recombinants displaying divergent yet phylogenetically-related mosaic genomes to CRF33_01B were identified and characterized, suggestive of an abrupt emergence of multiple novel CRF clades. Using rigorous maximum likelihood approach and the Bayesian Markov chain Monte Carlo (MCMC) sampling of CRF33_01Bpol sequences to elucidate the past population dynamics, we found that the founder lineages of CRF33_01B were likely to have first emerged among PWIDs in the early 1990 s before spreading exponentially to various high and low-risk populations (including children who acquired infections from their mothers) and later on became endemic around the early 2000 s. Taken together, our findings provide notable genetic evidence indicating the widespread expansion of CRF33_01B among PWIDs and into the general population. The emergence of numerous previously unknown recombinant clades highlights the escalating genetic complexity of HIV-1 in the Southeast Asian region. PMID:23667490

    Edible bird nests (EBNs) are consumed worldwide for various health benefits. EBNs are nests built from the saliva of swiftlets of Aerodramus species. The global market for EBNs is on the rise, especially from Hong Kong and mainland China. In the past, EBNs were harvested mainly from natural caves; however in the recent years, there has been a rapid growth of swiftlet farming. Little is known about the actual composition of EBNs except for protein, carbohydrate, ash and lipid contents, amino acids, vitamins and macro/ micronutrients. Besides the biochemical components of EBNs, are there any other structures that are associated with EBNs? This paper reports on the structural analysis of raw unprocessed farm and processed commercial EBNs. The raw EBNs were purchased from swiftlet farms in five locations in Peninsula Malaysia: Kuala Sanglang (Perlis; 6° 16' 0"N, 100° 12' 0"E), Pantai Remis (Perak; 4º 27' 0" N, 100º 38' 0" E), Kluang (Johor; 02º 012 303N 103º 192 583E), Kajang (Selangor; 2º 59' 0"N, 101º 47' 0"E) and Kota Bharu (Kelantan; 6º 8' 0"N, 102º 15' 0"E). The commercial nests were purchased from five different Chinese traditional medicinal shops (Companies A-E). A portion of each EBN was randomly broken into small fragments, attached to carbon tape and coated with gold and palladium particles for examination and photography under a scanning electron microscope. Structural analysis revealed the presence of mites, fungi, bacteria and feather strands on both the raw and commercial nests. Mite eggshells and faecal pellets, and body parts of other arthropods were seen only in the raw nests. The commercial nests had a variety of unidentified structures and substances coated on the nests' surfaces that were not found on the raw nests. The presence of these contaminants may jeopardise the quality of EBNs and pose health risks to consumers. Further identification of the mites and their allergens, fungi and bacteria are on-going and will be reported separately.

    The National Health & Morbidity Survey (NHMS) IV (2011) observed that the prevalence of obese children aged less than 18 years in Malaysia is 6.1% compared to 5.4% overweight and obese in NHMS III (2006). As such, this observation is of public health importance as obesity is a forewarning risk factor for chronic diseases such as type-2 diabetes, cardiovascular diseases (CVD) and certain types of cancers. This MyHeART (Malaysian Health and Adolescents longitudinal Research Team) study aims to examine risk factors of non-communicable diseases (NCD) among adolescents. The MyHeART study is longitudinal cohort study of 1361 schoolchildren (13-years old) attending 15 public secondary schools from the central (Kuala Lumpur and Selangor) and northern (Perak) regions of Peninsular Malaysia. The study used a stratified sampling design to select the study participants. Data collected at baseline included socio-economic, lifestyle (e.g. smoking, physical activity assessment, fitness assessment, seven-day diet history), and environmental information, anthropometric measurements, blood pressure, handgrip strength and bone mineral density. Blood samples for fasting blood glucose and lipid profiles, full blood count, renal profile, as well as bone profile and serum vitamin D were taken. This study cohort will be followed up again when participants turn 15, 17 and lastly, after a period of ten years (around the age of 27). Nine percent of the adolescents from this study were obese. More male participants smoked compared to female participants (15.4% vs. 4.7%). Adolescent males had higher fasting blood glucose but the female participants had lower high density lipoprotein (HDL-cholesterol) and higher low density lipoprotein (LDL-cholesterol). In addition, adolescents from the rural area had higher fasting blood glucose, diastolic blood pressure, total cholesterol and LDL-cholesterol. Our results demonstrated that adolescents from the rural area are at higher risk of NCDs compared to

It has been used for decades in folkloric practice for the amelioration of various ailments. In this study, the gastroprotective activity of methanolic extract of C. excavata leaves (MECE was determined in the Sprague Dawley rat ethanol-induced gastric ulcer model. Rats were pretreated with a single dose of vehicle (5% Tween 20, 20 mg/mL omeprazole, 400 and 200 mg/mL of MECE dissolved in 5% Tween 20. Ulcer was induced with 5 mL/kg of ethanol and stomach tissue was obtained after 1 hour. Histological examination was done on hematoxylin and eosin, periodic acid-Schiff, and immunochemically stained gastric mucosal tissues. Prostaglandin E2, superoxide dismutase, catalase, glutathione peroxidase, and lipid peroxidation levels of the gastric tissue homogenates were also determined. Significantly (P<0.05 smaller ulcer areas, less intense edema, and fewer leukocytes’ infiltration were observed in MECE- and omeprazole-treated than in untreated gastric mucosa with ulcer. The gastric pH, mucus production, superoxide dismutase, catalase, and glutathione peroxidase contents increased, while the lipid peroxidation content decreased as a result of MECE treatment. Bcl-2-associated X protein was underexpressed, while heat shock protein 70 and transforming growth factor-beta protein were overexpressed in the ulcerated gastric mucosa tissues treated with omeprazole and MECE.

    The diminishing fossil energy resources, coupled with heightened interest in the abatement of greenhouse gas emissions and concerns about energy security have motivated Malaysia to produce palm-based biodiesel and it has been started to be exported since 2006. In line with this issue, the government in Malaysia launched the palm-based biodiesel blending mandate of five percent (B5) in the federal administration of Putrajaya on 1{sup st} June 2011. This was then followed by four states: Malacca on July 11, Negeri Sembilan on August 1, Kuala Lumpur on September 1 and Selangor on October 1 of the same year but it is yet to be implemented nationwide. However what is the wise blend mandate to be chosen? Thus, this paper seeks to examine the possible impact of various blend mandates implementation (B2, B7 and B10) on the palm oil industry market variables (stock and price) since the main aim of biodiesel industry in Malaysia is to reduce domestic palm oil stock to below one million tones and provide a floor price to support Crude Palm Oil (CPO) prices at RM2,000 per tonne. A structural econometric model consisting of nine structural equations and three identities was proposed in this study. The model has been estimated by two stage least squares (2SLS) method using annual data for the period 1976-2013. The study indicates that counterfactual simulation of a decrease from B5 to B2 predicts a decrease (11.2 per cent) in CPO domestic consumption for biodiesel usage, 731.02 per cent reduction in CPO stock and an increase of 27.41 percent in domestic price of CPO. However the increase in the blend mandate from B5 to B7 and B10 suggest that domestic consumption of CPO for biodiesel purpose increase 7.40 and 18.55 percent respectively. The interesting findings in this study suggest that no matter whether Malaysian government increase or decrease the blend mandate the increase in the price of CPO are the same with an increase of is 27.41 percent.

    Chronic disease management presents enormous challenges to the primary care workforce because of the rising epidemic of cardiovascular risk factors. The chronic care model was proven effective in improving chronic disease outcomes in developed countries, but there is little evidence of its effectiveness in developing countries. The aim of this study was to evaluate the effectiveness of the EMPOWER-PAR intervention (multifaceted chronic disease management strategies based on the chronic care model) in improving outcomes for type 2 diabetes mellitus and hypertension using readily available resources in the Malaysian public primary care setting. This paper presents the study protocol. A pragmatic cluster randomised controlled trial using participatory action research is underway in 10 public primary care clinics in Selangor and Kuala Lumpur, Malaysia. Five clinics were randomly selected to provide the EMPOWER-PAR intervention for 1 year and another five clinics continued with usual care. Each clinic consecutively recruits type 2 diabetes mellitus and hypertension patients fulfilling the inclusion and exclusion criteria over a 2-week period. The EMPOWER-PAR intervention consists of creating/strengthening a multidisciplinary chronic disease management team, training the team to use the Global Cardiovascular Risks Self-Management Booklet to support patient care and reinforcing the use of relevant clinical practice guidelines for management and prescribing. For type 2 diabetes mellitus, the primary outcome is the change in the proportion of patients achieving HbA1c < 6.5%. For hypertension without type 2 diabetes mellitus, the primary outcome is the change in the proportion of patients achieving blood pressure < 140/90 mmHg. Secondary outcomes include the proportion of patients achieving targets for serum lipid profile, body mass index and waist circumference. Other outcome measures include medication adherence levels, process of care and prescribing patterns

This phytochemical has been previously reported to be drug-like with full compliance to Lipinski’s rule of five and good physicochemical properties when compared with 95% of orally available drugs. It has also been shown to possess unique medicinal properties that can be utilized in view of alleviating most human disease conditions. In this study, we investigated the cytotoxic mechanism of Artonin E in MCF-7 breast cancer cells, which has so far not been reported. In this context, Artonin E significantly suppressed the breast cancer cell’s viability while inducing apoptosis in a dose-dependent manner. This apoptosis induction was caspase dependent, and it is mediated mainly through the intrinsic pathway with the elevation of total reactive oxygen species

    Background The study on Clustering of Lifestyle risk factors and Understanding its association with Stress on health and wellbeing among school Teachers in Malaysia (CLUSTer) is a prospective cohort study which aims to extensively study teachers in Malaysia with respect to clustering of lifestyle risk factors and stress, and subsequently, to follow-up the population for important health outcomes. Method/design This study is being conducted in six states within Peninsular Malaysia. From each state, schools from each district are randomly selected and invited to participate in the study. Once the schools agree to participate, all teachers who fulfilled the inclusion criteria are invited to participate. Data collection includes a questionnaire survey and health assessment. Information collected in the questionnaire includes socio-demographic characteristics, participants’ medical history and family history of chronic diseases, teaching characteristics and burden, questions on smoking, alcohol consumption and physical activities (IPAQ); a food frequency questionnaire, the job content questionnaire (JCQ); depression, anxiety and stress scale (DASS21); health related quality of life (SF12-V2); Voice Handicap Index 10 on voice disorder, questions on chronic pain, sleep duration and obstetric history for female participants. Following blood drawn for predefined clinical tests, additional blood and urine specimens are collected and stored for future analysis. Active follow up of exposure and health outcomes will be carried out every two years via telephone or face to face contact. Data collection started in March 2013 and as of the end of March 2014 has been completed for four states: Kuala Lumpur, Selangor, Melaka and Penang. Approximately 6580 participants have been recruited. The first round of data collection and blood sampling is expected to be completed by the end of 2014 with an expected 10,000 participants recruited. Discussion Our study will provide a good basis

  3. Pain, instability, and familial discord: a qualitative study into women who use drugs in Malaysia.

    Out of 20,887 persons who use drugs that came into contact with the National Anti-Drugs Agency (NADA) officials in the year 2013, 3.2% were women. Because women who use drugs (WWUD) are often a hidden population, this may be an underestimate. International literature shows that women who use drugs face increased risk of HIV, intimate partner violence, and mental health issues. Similar literature in Malaysia is lacking, and thus, the objective of our study was exploratory in nature. Thirty-eight women who use drugs were interviewed using a semi-structured topic guide in Kelantan, Penang, Johor, Kuala Lumpur, and Selangor. Locations were chosen purposively. Nineteen women were interviewed individually and the remaining 19 were in focus group discussions (FGDs). All interviews were transcribed verbatim, translated to English, and analyzed with NVivo. Median age of respondents was 35.5 years old, 89.5% ethnic Malays, majority having married below the age of 20, and were of low socioeconomic backgrounds. Youngest age of initiation into drug use was 9 years old. Most reported is inhalation of amphetamine-type substances. Seven reported ever injecting. Three themes emerged: (a) repeating patterns of fluid family structures and instability; (b) "pain" and "difficulty" as features of home life; and (c) seeking marriage as a source of stabilization and practices of power within those marriages. Respondents often came from very fluid family environments and married to find stability, only to be drawn into a similar cycle. None of the women who had been separated from their children either institutionally, by family members, or by third parties, had accessed legal recourse for the loss of their parental rights. Unstable familial relationships or environments contributed to earlier initiation of drug use which raised questions about support services for WWUD and children who use drugs. Respondents were drawn into unstable and/or abusive relationships, perpetuating social

    The rapidly increasing uptake of e-cigarettes in Malaysia as of late demands a study to identify factors leading to its increased popularity and user intentions to quit smoking e-cigarettes. A convenience sample of e-cigarette smokers visiting e-cigarette retail shops in Selangor and Kuala Lumpur was recruited. The majority of e-cigarette smokers were youth in colleges or universities (39 %), and young professionals and managers (36 %). The main reasons for using e-cigarettes were to help the user quit tobacco cigarettes (88 %), the perception that e-cigarettes are not as intrusive as tobacco cigarettes (85 %) and can be used in public areas (70 %), the perception that e-cigarettes are healthier than tobacco cigarettes (85 %), and its relatively lower cost compared to tobacco cigarettes (65 %). A total of 65.3 % of respondents expressed intentions to quit e-cigarettes. In a multivariate analysis, the respondents who earned monthly income of RM1000 or less were significantly more likely to intend to quit smoking e-cigarettes [OR 1.551; 95 % CI 1.022-2.355; p = 0.015] compared to the respondents who earned a monthly income of more than RM2000. The respondents who disagreed with the statement 'Smoking e-cigs is relatively cheaper compared to tobacco cigarettes' were significantly more likely to intend to quit smoking e-cigarettes [OR 1.548; 95 % CI 1.045-2.293; p = 0.027] compared to respondents who did not agree. e-cigarette preventive interventions should target areas related to the identified main reasons for using e-cigarettes, namely as an aid for quitting tobacco cigarettes, the perception that e-cigarettes are not as intrusive as tobacco cigarettes and can be used in public areas, the idea that e-cigarettes are healthier than tobacco cigarettes, and its relatively lower cost compared to tobacco cigarettes.

    Full Text Available While healthcare costs for rotavirus gastroenteritis requiring hospitalization may be burdensome on households in Malaysia, exploration on the distribution and catastrophic impact of these expenses on households are lacking.We assessed the economic burden, levels and distribution of catastrophic healthcare expenditure, the poverty impact on households and inequities related to healthcare payments for acute gastroenteritis requiring hospitalization in Malaysia.A two-year prospective, hospital-based study was conducted from 2008 to 2010 in an urban (Kuala Lumpur and rural (Kuala Terengganu setting in Malaysia. All children under the age of 5 years admitted for acute gastroenteritis were included. Patients were screened for rotavirus and information on healthcare expenditure was obtained.Of the 658 stool samples collected at both centers, 248 (38% were positive for rotavirus. Direct and indirect costs incurred were significantly higher in Kuala Lumpur compared with Kuala Terengganu (US$222 Vs. US$45; p<0.001. The mean direct and indirect costs for rotavirus gastroenteritis consisted 20% of monthly household income in Kuala Lumpur, as compared with only 5% in Kuala Terengganu. Direct medical costs paid out-of-pocket caused 141 (33% households in Kuala Lumpur to experience catastrophic expenditure and 11 (3% households to incur poverty. However in Kuala Terengganu, only one household (0.5% experienced catastrophic healthcare expenditure and none were impoverished. The lowest income quintile in Kuala Lumpur was more likely to experience catastrophic payments compared to the highest quintile (87% vs 8%. The concentration index for out-of-pocket healthcare payments was closer to zero at Kuala Lumpur (0.03 than at Kuala Terengganu (0.24.While urban households were wealthier, healthcare expenditure due to gastroenteritis had more catastrophic and poverty impact on the urban poor. Universal rotavirus vaccination would reduce both disease burden and health

This study aimed to determine the in vitro cytoxicity of its leaf solvent extracts as well as the in vivo wound healing and antioxidant activities of the methanolic extracts of C. excavata (MECE. HaCaT (keratocyte and Vero cell lines were used for evaluation of the in vitro cytotoxic effects, while the in vivo wound healing and antioxidant activities were determined in skin wounds inflicted on rats. Twenty adult male Sprague-Dawley rats were divided into five groups of four animals each. Approximately 3.14 cm2 excisional wound was inflicted on the nape of each rat following anesthesia. The treatment groups received topical application of MECE at 50 mg/mL (MECE-LD [low dose], 100 mg/mL (MECE-MD [medium dose], and 200 mg/mL (MECE-HD [high dose], while the negative control group was treated with gum acacia in normal saline and the positive control group with intrasite gel. Wound contraction was evaluated on days 5, 10, and 15 after wound infliction, and tissue from wound area was collected at day 15 post-wound infliction for antioxidant enzyme evaluation and histopathological analyses. Generally, Vero cells were more resistant to the cytotoxic effects of the solvent extracts as compared with HaCaT cells. Chloroform (CH and ethyl acetate (EA extracts of C. excavata were toxic to HaCaT cells at 200 and 400 µg/mL, but the same concentrations showed higher (P<0.05 viability in Vero cells. There was significantly (P<0.01 greater wound

    Full Text Available Objective: To investigate antibiotics and heavy metals resistance profile of Aeromonas species isolated from Kuala Gula and Kuala Sepetang, Perak. Methods: Isolated Aeromonas species were subjected to 12 antibiotics: penicillin G 10 units, tetracycline 30 µg, novobiocin 5 µg, nitrofurantoin 100 µg, ampicillin 10 µg, chloramphenicol 10 µg, fluconazole 25 µg, gentamicin 10 µg, streptomycin 10 µg and 25 µg, kanamycin 30 µg, and vancomycin 30 µg and 5 heavy metals: MnSO4.H2O, Cr(NO3.9H2O, CuSO4, Pb(NO32, HgCl2. Results: Results from this study revealed that isolates from the two sources-displayed varied resistance. Isolates from Kuala Sepetang showed 91%, 66%, 61%, and 52% resistance to vancomycin, Novobiocin, streptomycin and gentamycin while Kuala Gula isolates showed 76%, 93%, 28% and 14% respectively. High rate of resistance was shown to be against lead (Pb, Chromium (Cr, copper (Cu and Manganese (Mn with minimum inhibitory concentration ranging from 2 560 µg/mL to >5 120 µg/mL. Low resistance to mercury was observed among isolates from Kuala Gula. Conclusions: This study showed that there was widespread of both heavy metals and antibiotics resistance among Aeromonas isolates from the two marine sources with isolates from Kuala Sepetang showing more resistance thereby posing danger to both aquatic animals and human health.
