  1. Attempted suicide in Kuala Lumpur.

    PubMed

    Habil, M H; Ganesvaran, T; Agnes, L S

    A total of 306 patients were admitted to the University Hospital in Kuala Lumpur in 1989 after attempting suicide. Fourteen of them succumbed to injuries. Psychosocial data of 296 patients out of the 306 survivors are reported. Suicidal behaviour is more common in the young and especially amongst the females. Nearly 45.0% of them are from social class IV and V. Persons of Indian ethnic origin are overrepresented, while in Malays suicidal behavior seemed to be less common. Self-poisoning was reported to be the commonest method in attempting suicide. Diagnosis of adjustment disorder was made in 58.5% of the patients. Two-thirds of the patients had an intention score of less than 10 on the Pierce's Scale.

  2. Low birth weight in Kuala Lumpur.

    PubMed

    Tahir, H M; Ismail, N N; Gebbie, D A

    1991-06-01

    Low birth weight babies are defined as those weighing under 2,500 g. They make 13.5% of all births at the Maternity Hospital, Kuala Lumpur but contribute to 74.8% of all deaths. They are most likely to be Indian babies and least likely to be Chinese. Among all 3 communities, the primigravidae tend to produce smaller babies than multiparae but this is also true for the Indian of parity more than 3. The Malay teenager is more likely to produce small babies than their older counterparts but not so with the Indian and Chinese. There are definite clinical factors associated with or causing the births of small babies and the lighter the baby, the more influential are these factors. Maternal hypertension, antepartum haemorrhage, multiple pregnancy and unexplained intrauterine death are the 4 outstanding associations with both low birth weight and perinatal death. Although the spontaneous (often premature) onset of labour was the commonest preceding factor, it was much less important in the lowest birth weight groups of babies and was a less important contributor to perinatal death.

    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.

  4. The seroepidemiology of rubella in Kuala Lumpur, West Malaysia.

    1972-01-01

    Rubella antibody rates in the female population of Kuala Lumpur were lower than those reported from temperate countries, though similar to rates found in other tropical countries excepting Singapore. Among the major ethnic groups, the immunity status of the Chinese was higher than that of the Malay and Indian groups.

  5. Legionella species isolated from cooling towers in Kuala Lumpur.

    PubMed

    Ngeow, Y F; Tan, C H; Lim, S Y

    1992-03-01

    Three building complexes in Kuala Lumpur were surveyed for the presence of legionellae in cooling towers. The organisms were grown from 12 out of 46 samples of water collected from 30 towers. L. pneumophila serogroups 1 and 7 were the commonest serogroups isolated. None belonged to the Pontiac subgroup of L. pneumophila serogroup 1.

    Desa, M. N.; Niemczynowicz, J.

    Knowledge of temporal and spatial characteristics of rainfall in Kuala Lumpur, Malaysia is still lacking and they are still considered important for more efficient management of the implemented urban water resources projects. In view of this, a study was conducted to characterise the historical rainfall phenomena (from 1982 to 1992). Statistical properties of annual, monthly, and minutes rainfall were derived. Spatial correlation fields for the annual and monthly rainfalls were studied. The results showed that the temporal and spatial characteristics of rainfall in this region were pronounced, even on the basis of two groups of monthly rainfall. Thus they give the basis for further understanding of rainfall processes in Kuala Lumpur region and, in general, in humid tropics.

  7. Pattern of alcoholism in the General Hospital, Kuala Lumpur.

    Saroja, K I; Kyaw, O

    1993-06-01

    This study establishes the prevalence rate for alcoholism among the inpatients of the General Hospital, Kuala Lumpur, as 11%, but as 25% among the drinking population. It also describes the demographic profile of the alcoholic as compared to the non-alcoholic drinker and the non-drinker and suggests that certain vulnerability factors could contribute to the development of alcoholism. A trend noted is also the changing racial trends in the use of alcohol.

    1996-03-01

    Primary biliary cirrhosis is an uncommon disease amongst Malaysians. Over a 12-year period, between 1979 and 1991, only seven patients with clinical, biochemical and histologic evidence of primary biliary cirrhosis were identified in University Hospital Kuala Lumpur. All were Chinese females between the ages of 30 to 55 years. The presenting complaint was pruritus in 5 patients. All except one patient was jaundiced when the diagnosis was made. These patients were followed up from 1 to 11 years. Three deaths were reported, one from massive hemetemesis and two from liver failure.

  10. Incidence of Listeria spp. in vegetables in Kuala Lumpur.

    PubMed

    Tang, M Y; Cheong, Y M; Zainuldin, T

    1994-09-01

    From April 1992 to September 1992, 280 samples of 10 different fresh vegetables, bought from four different market outlets in Kuala Lumpur were examined for the presence of Listeria spp. Most of the market produce were locally grown with the exception of carrots. The isolation procedure was based on the Food & Drug Administration method (modified) used for the detection of Listeria spp. Isolation media used were Listeria Selective medium and LiCl- phenylethanol-Moxalactam agars. The identification of isolates was by means of conventional biochemical tests and API Listeria identification system. Five out of the 280 samples showed Listeria contamination, Listeria monocytogenes was isolated in lettuce, sengkuang (Pachyrrhizus erosus) and selom Oenanthe javanica) and Listeria innocua was isolated from sengkuang (Pachyrrhizus erosus) and pegaga (Hydrocotyle asiatica).

    1990-04-01

    Twenty patients with Myelodysplastic Syndrome (MDS) were diagnosed in University Hospital, Kuala Lumpur over a 5 year period. They were subclassified using the French American British (FAB) criteria. 90% of the patients were above 40 years old and the sex ratio was about equal. The predominant presenting symptom was anaemia and there was paucity of physical signs at presentation. Patients with 'aggressive' subtypes of MDS i.e. refractory anaemia with excess blasts (RAEB), refractory anaemia with excess blasts in transformation (RAEB(-)+) and chronic myelomonocytic leukaemia (CMML) had more frequent thrombocytopenia and neutropenia and their marrow pictures frequently had dysmegakaryopoiesis and dysgranulopoiesis as compared to more the "benign" subtypes i.e. refractory anaemia (RA) and refractory leukaemic anaemia with ringed sideroblasts (RARS). Four patients had leukaemic transformation and all of them came from the 'aggressive' subtypes. The current views on treatment of MDS are discussed.

    1990-08-01

    This study was undertaken to analyse the clinical spectrum of chronic liver disease (cirrhosis, and others with portal hypertension) in Kuala Lumpur. Eighty patients were diagnosed over a 6-year period. Twenty-two had biopsy proven cirrhosis while 58 others had portal hypertension with clinical and biochemical evidence of chronic liver disease. The commonest aetiology was alcohol (36%), followed by the idiopathic variety and hepatitis B. The male to female ratio was 4.4:1. Indians had a high prevalence of alcohol-associated chronic liver disease. Overall, ascites was the commonest presentation. Eight patients presented with hepatocellular carcinoma. Spontaneous bacterial peritonitis was diagnosed in 13% of patients undergoing abdominal paracentesis. Gallstones were detected in 37% of patients who underwent ultrasonography. Diabetes mellitus and peptic ulcer disease were noted in 22% and 31% of patients respectively.

    1991-09-01

    The microbial aetiology of genital ulcers was studied in 249 patients (241 men and 8 women) attending a Sexually Transmitted Disease Clinic in Kuala Lumpur, Malaysia. Herpes simplex virus type 2 was isolated in 48 (19.2%) patients, Haemophilus ducreyi from 22 (8.8%), Neisseria gonorrhoeae from seven (2.8%) and Chlamydia trachomatis from four (1.6%). Syphilis was diagnosed in 18 (7.2%) patients on the basis of dark field microscopy. Two (0.8%) patients were found to have both chancroid and syphilis and one (0.5%) had both gonorrhoea and syphilis. No organism was isolated in the remaining 151 (61.5%) patients. Overall, the accuracy of clinical diagnosis was 58% for single infection, 67% for herpes, 63% for syphilis, 47% for chancroid and 0% for lymphogranuloma venereum. Therefore, our study confirms the need for laboratory tests to diagnose accurately the aetiology of genital ulcer disease.

    The aims of this study were to determine the types of cancers and hematological disorders in patients attending a pediatric hematology-oncology clinic. This was a prospective study at the Pediatric Institute, General Hospital Kuala Lumpur, Malaysia from June 2005-November 2006. During the 18-month study, 803 patients attended the clinic, 730 had oncological problems and 73 had hematological problems. The age range was from 2 months to 28 years (median 6 years). The patients were Malay (66%), Chinese (23%), Indian (10%) and other races (1%). Of the oncological patients, 51% had either leukemia (n=293) or lymphoma (n=77). The other most common diagnoses were retinoblastoma, followed by Wilm's tumor and germ cell tumors. Six patients (0.8%) developed a second malignant neoplasm. Of the hematological patients, 60% had platelet disorders, most commonly chronic immune thrombocytopenic purpura. Twenty-four per cent had bone marrow failure and 16% had red cell disorders.

    National data on maternal health status in Malaysia is minimal. These data, from Maternity Hospital, Kuala Lumpur, are presented toward the goal of accumulation of basic information. From 1978-81, there were 74,105 deliveries and 9,899 abortion admissions in this hospital, which serves as a referral center for areas within a 100-mile radius. 39 maternal mortalities were recorded in this time. Maternal mortality excluding that associated with abortions was 29.27/100,000 births; when abortions are included, the figure increases to 70.54. 50% of the women who died were under 30 years of age. 28.2% of deaths occurred among primigravida, and 25.64% were associated with parity 5 or above. Malays had a mortality rate double that of Chinese or Indians. Major causes of death were toxemia, hemorrhage, embolism, medical disease, and sepsis. These causes accounted for 89% of deaths, while the remaining 11% were due to uterine inversion, obstetric trauma, and pulmonary edema. Avoidable factors were isolated in all the deaths except 3, 1 due to infective hepatitis, and 2 due to cardiac disease. Inefficient hospital care occurred in 17 patients, defective care before admission in 2, and 4 death were associated with patients' failure to seek or accept medical attention. The need for documenting all maternal mortalities is a priority in Malaysia.

  16. Hepatitis delta virus in intravenous drug users in Kuala Lumpur.

    1994-09-01

    The hepatitis delta virus (HDV) is an RNA containing virus that requires hepatitis B virus (HBV) to supply the envelope proteins. HDV only infect man in the presence of HBV, either as a coinfection or as superinfection in HBV carriers. In the presence of hepatitis B infection, the HDV may cause more severe liver damage than that caused by the hepatitis B virus alone. HDV infection was studied in 44 HBsAg positive serum samples collected from male intravenous drug users sent for screening to the Blood Services Centre (BSC), Hospital Kuala Lumpur (HKL) between 1990 and 1992. The majority (39) were in the 20 to 39 age group. The youngest was 19 years old and the oldest was 61 years old. There were 25 Malays, 13 Chinese, five Indians and one Albanian. Anti hepatitis delta antibody (Anti-HDV) was detected in 15 out of 44 (34%) of the drug addicts. These results shows an increased in delta infection in HBsAg positive intravenous drug addicts compared to the surveillance results in 1985 when no delta antibodies were detected, and the 1986 and 1989 surveillance which showed 17.8% and 20% delta antibody positivity respectively.

    The review of past researches discussed that factors such as climate change and movement toward urbanization will result in more frequent and severe disasters in the near future (Yasuhara et al., 2011). Flash flood is the most common type of disaster that residents of Kuala Lumpur (KL) come across, thus in this study, it was desired to discover the factors affecting preparedness among residents of KL as well as assessing the variation of individual preparedness among residents. With the aid of SPSS analysis, the reliability of data, correlation and regression analysis between the investigated factors and disaster preparedness were obtained. According to this research it was found that level of preparedness of residents of KL is still below average; majority of social demographic indicators such as income, education, age, and property ownership showed significant contribution to the variation of disaster preparedness among the residents. For instance men were much more prepared in comparison to women; residents with high level of income and education had also significantly higher preparedness compared to those with low level of income and education. Race was the only factor that differs from the findings of previous studies; since race does not affect the preparedness.

    One hundred and fifty one house rats, Rattus rattus diardii from five different localities, Jinjang, Dato Keramat, Kuala Lumpur, Sungai Besi and Selayang Baru, were examined for parasites. Nineteen species of parasites were recovered. Hymenolepis diminuta and Nippostrongylus brasiliensis are the predominant species. The dominancy of the parasite species in the rats differed in each locality: Hymenolepis diminuta in Dato Keramat and Kuala Lumpur; Nippostrongylus brasiliensis in Sungai Besi; Gongylomena neoplasticum in Jinjang and Selayang Baru. The influences of human habitats on the parasite fauna of house rats are discussed.

    Paediatric intensive care in Malaysia is a developing subspecialty with an increasing number of specialists with a paediatric background being involved in the care of critically ill children. A part prospective and part retrospective review of 118 consecutive non-neonatal ventilated patients in University Hospital, Kuala Lumpur was carried out from 1 June 1995 to 31 December 1996 to study the clinical epidemiology and outcome in our paediatric intensive case unit (PICU). The mean age of the patients was 33.9 +/- 6.0 months (median 16 months). The main mode of admission was emergency (96.6 per cent) with an overall mortality rate of 42 per cent (50/118). The mean paediatric risk of mortality (PRISM) score was 20 +/- 0.98 SEM, with 53 per cent of patients having a score of over 30 per cent. Multiorgan dysfunction (MODS) was identified in 71 per cent of patients. Admission efficiency (mortality risk > 1 per cent) was 97 per cent. Standardized mortality rate using PRISM was an acceptable 1.06. The main diagnostic categories were respiratory (32 per cent), neurology (22 per cent), haematology-oncology (18 per cent); the aetiology of dysfunction was mainly infective. Non-survivors were older (29.5 vs. 13.8 months, p < 0.0001), had more severe illness (mean PRISM score 30 vs. 14, p < 0.0001), were more likely to develop MODS (96 vs. 53 per cent, p < 0.0001) and required more intervention and monitoring. Paediatric intensive care in Malaysia differs widely from that in developed countries in patient characteristics, severity of illness, and care modalities provided.

    Anopheles donaldi Reid, a member of the A. barbirostris species group, is a vector of human filariasis and probably malaria. The discovery of some old specimens of this species, collected in Kuala Lumpur town where it no longer occurs, together with evidence from the literature about past malaria in the town, suggest that donaldi may have played a part in transmitting that malaria.

    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 < 0.001). Nevertheless, when this pattern was further analyzed according to month by each zone within Kuala Lumpur, two distinct patterns were observed which include a clustered pattern (R value < 1) between April to June and a dispersed pattern (R value > 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

    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. PMID:12314885

    Despite advancements in endoscopy and pharmacology in the treatment of peptic ulcer disease the overall mortality has remained constant at 10% for the past four decades. The aim of this study was to determine the age, gender, racial distribution, incidence and causes of endoscopically diagnosed cases of upper gastrointestinal (UGI) bleeding to summarise treatments undertaken and to report their outcome. A prospective study of UGI bleeding in 128 patients was performed in two surgical wards of Kuala Lumpur Hospital, involving both elective and emergency admissions. The study group comprised of 113 (88.2%) males and 15 (11.7%) females. The mean age was 51.9 years (range 14 to 85 years) and 37.5% (48 of 128 patients) were older than 60 years. The Indian race was over-represented in all disease categories. Smoking (50.1%), alcohol consumption (37.5%), non-steroidal anti-inflammatory drugs (NSAIDs) (17.2%), traditional remedies (5.5%), anti-coagulants (2.3%) and steroids (0.8%) were among the risk factors reported. Common presenting symptoms and signs included malaena (68.8%), haematemesis (59.4%) and fresh per rectal bleeding (33.6%). The commonest causes of UGI bleeding were duodenal ulcer (32%), gastric ulcer (29.7%), erosions (duodenal and gastric) (21.9%), oesophageal varices (10.9%) and malignancy (3.9%). UGI bleeding was treated non-surgically in 90.6% of cases. Blood transfusions were required in 62.6% (67/107) of peptic ulcer disease patients. Surgical intervention for bleeding peptic ulcer occurred in around 10% of cases and involved under-running of the bleeding vessel in most high risk duodenal and gastric ulcer patients. The overall mortality from bleeding peptic ulcer disease was 4.7%. Six patients died from torrential UGI haemorrhage soon after presentation, without the establishment of a cause. Active resuscitative protocols, early endoscopy, more aggressive interventional therapy, early surgery by more senior surgeons, increasing intensive care unit

    1993-06-01

    A survey conducted to assess the extent which the urban poor in rapidly expanding Kuala Lumpur utilize maternal and child health services available to them. The sample consisted of 1,380 households with children below 6 years and yielded 1,233 children below 6 years of age. 74% of the children had been delivered in government hospitals and 86% of the pregnancies had antenatal care in governmental establishments. 89.2% had BCG immunization before they were 1 year old but 13.3% had not received DPT by that age. Immunization was mainly done in government clinics. The overall immunization coverage for the whole of Kuala Lumpur is expected to be higher than these figures limited to the urban poor. Health planners should increase health facilities in the city to accommodate the expanding population. There is a need to continually campaign for immunization to improve coverage among the urban poor.

    The predictors of severe disease or death were determined for 85 melioidosis patients in Kuala Lumpur, Malaysia. Most of the patients were male, > 40 years old, and diabetic. Severe disease or death occurred in 28 (32.9%) cases. Lower lymphocyte counts and positive blood cultures were significant independent predictors of severe disease, but age, presentations with pneumonia, inappropriate empirical antibiotics, or flagellin types of the infecting isolates were not. Knowledge of local predictors of severe disease is useful for clinical management.

    Influenza B virus causes significant disease but remains understudied in tropical regions. We sequenced 72 influenza B viruses collected in Kuala Lumpur, Malaysia, from 1995 to 2008. The predominant circulating lineage (Victoria or Yamagata) changed every 1 to 3 years, and these shifts were associated with increased incidence of influenza B. We also found poor lineage matches with recommended influenza virus vaccine strains. While most influenza B virus lineages in Malaysia were short-lived, one circulated for 3 to 4 years.

    A good overall assessment of the severity of illnesses of patients admitted to a general intensive care unit (ICU) is not without problems. The APACHE (acute physiology and chronic health evaluation) prognostic scoring system enables us to stratify acutely ill patients and compare efficiency of ICU therapy in different hospitals. This preliminary study carried out on 100 consecutive admissions to the ICU in University Hospital, Kuala Lumpur showed the spectrum of ICU admissions and the direct relationship between APACHE II score and mortality.

    2015-01-01

    Background: Studies from the West have demonstrated that ready-to-eat cereals (RTECs) are a common form of breakfast and more likely to be consumed by children. This study aimed to investigate the breakfast eating pattern and RTECs consumption among schoolchildren in Kuala Lumpur. Methods: In this cross-sectional study, a total of 382 schoolchildren, aged 10 and 11 years old, were recruited from seven randomly selected primary schools in Kuala Lumpur. Information on socio-demographics, breakfast eating patterns, and perceptions of RTECs and dietary intake (24-hour dietary recalls) were obtained. Results: Among the respondents, only 22% of them consumed breakfast on a regular basis. The most commonly eaten food by children at breakfast was bread (27.2%), followed by biscuits (22.2%) and RTECs (20.5%). The majority of them (93%) reported that they consumed RTECs sometimes during the week. Chocolate RTECs (34.1%), corn flake RTECs (30.3%), and RTECs coated with honey (25.1%) were the most popular RTECs chosen by children. Respondents who consumed RTECs showed a significantly higher intake in calories, carbohydrate, vitamin A, vitamin B1, vitamin B2, vitamin B3, folate, vitamin C, calcium, iron, and fibre (P < 0.05), compared to those who skipped breakfast and those who had breakfast foods other than RTECs. Conclusion: The lower levels of breakfast consumption among schoolchildren in Kuala Lumpur need serious attention. RTEC is a nutritious food which is well accepted by a majority of the schoolchildren in Kuala Lumpur. Nutrition intervention should be conducted in the future to include a well-balanced breakfast with the utilisation of RTECs for schoolchildren. PMID:25892948

    The radiation dose received by man from indoor radon and its progeny is the largest at more than 50% of total dose received. The seasonal variation of indoor radon concentration in Kerala, India and Kuala Lumpur, Malaysia were studied. The Southwest coast of the Kerala state in India is known to have very high levels of natural background radiation owing to the rare earths rich monazite sand available in large amount. Kuala Lumpur, Malaysia used to be a famous tin mining area where it was done using open cast system. One-year measurements of radon concentration in houses were done for these two regions. It was found that there is considerable seasonal variation in the levels of radon in Kerala but the variation in Kuala Lumpur is only less than 10%.

    This study examined admissions, final diagnoses and mean duration of stay of patients in the Psychiatric Wards at the General Hospital, Kuala Lumpur. The male ward was severely overcrowded by 125% over the maximum bed capacity. The majority were psychotic, mainly schizophrenic. The female ward had 76% occupancy, also mainly psychotic. Neurotics, alcohol dependents and personality disorders formed less than 5% of the admissions. There was no difference in the mean duration of stay of patients of both UKM and GHKL Units stratified for diagnosis and disposal except for newly diagnosed schizophrenics. There is an urgent need for more male psychiatric beds/wards.

    Fourteen patients who presented to the University Hospital of Kuala Lumpur between June 1981 and June 1991 were reviewed retrospectively. Nasal septal abscesses are uncommon and therefore there are limited reports in the medical literature. Early diagnosis and immediate therapy is mandatory to avoid cosmetic nasal deformity or intracranial infection. Two out of the fourteen patients developed saddle nose deformity and septal perforation because of delay in treatment, the cases were misdiagnosed by non-otolaryngologist as turbinates swelling. The leading cause of nasal septal abscess was non-surgical trauma which accounted for about 85.7%. The commonest pathogenic organism isolated from the pus of nasal septal abscess was Staphylococcus aureus.

    The aim of the present study was to determine the vertical distribution and abundance of Aedes mosquitoes in multiple storey buildings in Selangor and Kuala Lumpur, Malaysia. Ovitrap surveillance was conducted for 4 continuous weeks in multiple storey buildings in 4 residential areas located in Selangor [Kg. Baiduri (KB)] and Kuala Lumpur [Student Hostel of University of Malaya (UM), Kg. Kerinchi (KK) and Hang Tuah (HT)]. The results implied that Aedes mosquitoes could be found from ground floor to highest floor of multiple storey buildings and data from different elevation did not show significant difference. Ovitrap index for UM, KB, HT and KK ranged from 0 - 29.17%, 0 - 55.56%, 8.33 - 83.33% and 0 - 91.17% respectively. Aedes aegypti and Aedes albopictus were found breeding in HT, KK and KB; while only Ae. albopictus was obtained from UM. The results indicate that the invasion of Aedes mosquitoes in high-rise apartments could facilitate the transmission of dengue virus and new approaches to vector control in this type of residential area should be developed.

    A survey was undertaken to investigate the prevalence of intestinal and blood parasites among wild rats in urban area of Kuala Lumpur, Malaysia. A total of 137 stool and blood samples were collected from wild rats from Sentul and Chow Kit areas. Five species of rats were captured and supplied by Kuala Lumpur City Hall. The most common was Rattus rattus diardii (Malayan Black rat), 67%, followed by Rattus norvegicus (Norway rat), 10%, Rattus argentiventer (rice-field rat), 10%, Rattus tiomanicus (Malaysian field rat), 9% and Rattus exulans (Polynesian rat), 4%. Rattus rattus diardii is commonly known to live in human environment and they are normally identified as pests to human community. More male rats were captured (61%) compared to female (39%). Out of 137 samples, 81.8% samples were positive with intestinal parasites, with 86.2% from Sentul area and 78.5% from Chow Kit area. Six different parasites were detected. The most common intestinal helminth parasite detected was Nippostrongylus brasiliensis (80.3%), followed by Hymenolepis nana (23.4%), Capillaria hepatica (13.9%) and Hymenolepis diminuta (2.9%). Intestinal protozoan detected was Entamoeba histolytica/E. dispar (8.8%). Trypanosoma lewisi (1.5%) was the only blood parasite detected.

    Cervical cancer is one of the most frequent cancers in women worldwide. Persistent infection with a human papillomavirus (HPV) is the main cause for cervical cancer. Vaccination and Pap smear screening are the best methods for prevention of the disease. The objective of this cross-sectional study was to assess the knowledge and views of upper secondary school female students in Kuala Lumpur, Malaysia, toward prevention of cervical cancer. This study was conducted from April 2009 to September 2009 in 8 schools in Kuala Lumpur area using pre-tested and validated questionnaires. Results indicated that the respondents had low knowledge of cervical cancer and its prevention although the majority of students (80.4%) had heard about the disease. The level of knowledge of cervical cancr and its prevention was significantly higher among students from the science stream (p<0.001) compared to students from the art stream. Most students (69.3%) agreed to take the vaccination if the service was available in schools. A high percentage of students (82.2%) agreed that the vaccination should be compulsory to the students. In conclusion, most students had low knowledge of cervical cancer and its prevention but they had positive attitude toward vaccination and agreed that vaccination should be compulsory. Therefore, suitable educational programmes should be developed to improve the knowledge of secondary school students on the prevention of cervical cancer.

    Relatively little is known about the burden of influenza in tropical countries. The seroprevalence of pandemic influenza A (H1N1) 2009, seasonal H1N1 and H3N2 was determined in Kuala Lumpur, Malaysia. Pre- and post-pandemic residual laboratory sera were tested by hemagglutination-inhibition. The seroprevalence of A(H1N1)pdm09 increased from 3.7% pre-pandemic to 21.9% post-pandemic, giving an overall cumulative incidence of 18.1% (95% CI, 13.8-22.5%), mainly due to increases in those <5, 5-17, and 18-29 years old. In contrast with findings from USA, Europe, and Australia, pre-existing seroprevalence to A(H1N1)pdm09 was low at 5.6% in the elderly age group of >55 years. A(H1N1)pdm09 affected almost a third of those <30 years in Kuala Lumpur. Pre-pandemic seroprevalence was 14.7% for seasonal H1N1 and 21.0% for H3N2, and these rates did not change significantly after the pandemic. Seasonal and pandemic influenza cause a considerable burden in tropical Malaysia, particularly in children and young adults.

  17. The nutritional situation in metropolitan Kuala Lumpur, with focus on squatters.

    PubMed

    Lin, K G

    1992-01-01

    Kuala Lumpur is the capital city of Malaysia with an estimated population of 1.55 million. Approximately 12% of the population live in squatter settlements occupying about 7% of the city total area. The squatter settlements generally are provided with basic amenities such as piped water, toilet facilities and electricity. Health indicators for the overall population of Kuala Lumpur are better off than for the rest of the country; however, intra-city differentials prevail along ethnic and socio-economic lines. Malays and Indians have higher rates for stillbirths, and neonatal, infant and toddler mortality than the Chinese. The wide disparity in the socio-economic status between the advantaged and the poor groups in the city is reflected in the dietary practices and nutritional status of young children from these communities. The percentage of preschool children from urban poor households with inadequate intakes of calories and nutrients is two to three times higher than those from the advantaged group. Compared to rural infants, a lower percentage of urban infants are breastfed. A lower percentage of Malays from the urban advantaged group breastfed, compared with the urban poor group. The reversed trend is found for the Chinese community. Growth attainment of young children from the urban poor is worse than the urban advantaged, though better than the rural poor. Health and nutritional practices implications related to both undernutrition and overnutrition are discussed, to illustrate the twin challenges of malnutrition in the city.

    A study was carried out to determine the chemical composition of bulk precipitation, throughfall and stemflow in an urban forest in Kuala Lumpur, Malaysia. The mean weekly rainfall recorded during the period of study was 63.2 mm. Throughfall, stemflow and canopy interception of incident precipitation were 77.1%, 1.2% and 21.7% respectively. Bulk precipitation, througfall and stemflow were acidic, the pH recorded being 4.37, 4.71 and 4.15 respectively. In all cases the dominant ions were NO3, SO4, Cl, NH4, K, Ca and Na. Of the ions studied Ca, K, Cl, SO4, Mg and Mn showed net increases in passing through the forest canopy, while NH4, Na, NO3, Zn, H and Fe showed net retention. This study shows that the urban environment of Kuala Lumpur contributes considerable amounts of materials to the atmosphere, as reflected by the high ionic contents in bulk precipitation, throughfall and stemflow.

    Background: Cryoprecipitate is generally used to treat bleeding patients with hypofibrinogenemia, and the transfusion decision is guided based on published guidelines. Aim: This study aimed to evaluate the practice appropriateness in accordance to cryoprecipitate transfusion guidelines in Hospital Kuala Lumpur. Methodology: This cross-sectional study of 117 cryoprecipitates transfused adult patients was conducted in Kuala Lumpur Hospital from January to June 2012. The compliance of the indication of cryoprecipitate was considered as appropriate if indicated for patients who have hypofibrinogenemia (<1.0 g/L) with bleeding, or otherwise inappropriate if pretransfusion fibrinogen level was more than 1.0 g/L, pretransfusion fibrinogen level was not examined and posttransfusion fibrinogen level more than 1.5 g/L. Results: Most of the cryoprecipitate prescriptions were found to be inappropriate, which read 81.2% (95% confidence interval = 0.740, 0.880). Patients who underwent neurovascular surgery were the major recipient of cryoprecipitate, but majority of the prescription was found not appropriate. The decision to transfuse cryoprecipitate was found mostly appropriate when was guided by fibrinogen (52.2%), but the percentage dropped to 10.6% when pretransfusion fibrinogen test was not performed. Regrettably, only 19.7% of total cryoprecipitate were given based on pretransfusion fibrinogen level.

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

    PubMed

    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.

    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.

    Kuala Lumpur is the capital city of Malaysia with an estimated population of 1.55 million. Approximately 12% of the population live in squatter settlements occupying about 7% of the city total area. The squatter settlements generally are provided with basic amenities such as piped water, toilet facilities and electricity. Health indicators for the overall population of Kuala Lumpur are better off than for the rest of the country; however, intra-city differentials prevail along ethnic and socio-economic lines. Malays and Indians have higher rates for stillbirths, and neonatal, infant and toddler mortality than the Chinese. The wide disparity in the socio-economic status between the advantaged and the poor groups in the city is reflected in the dietary practices and nutritional status of young children from these communities. The percentage of preschool children from urban poor households with inadequate intakes of calories and nutrients is two to three times higher than those from the advantaged group. Compared to rural infants, a lower percentage of urban infants are breastfed. A lower percentage of Malays from the urban advantaged group breastfed, compared with the urban poor group. The reversed trend is found for the Chinese community. Growth attainment of young children from the urban poor is worse than the urban advantaged, though better than the rural poor. Health and nutritional practices implications related to both undernutrition and overnutrition are discussed, to illustrate the twin challenges of malnutrition in the city. PMID:1342754

    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.

    Background: Cryoprecipitate is generally used to treat bleeding patients with hypofibrinogenemia, and the transfusion decision is guided based on published guidelines. Aim: This study aimed to evaluate the practice appropriateness in accordance to cryoprecipitate transfusion guidelines in Hospital Kuala Lumpur. Methodology: This cross-sectional study of 117 cryoprecipitates transfused adult patients was conducted in Kuala Lumpur Hospital from January to June 2012. The compliance of the indication of cryoprecipitate was considered as appropriate if indicated for patients who have hypofibrinogenemia (<1.0 g/L) with bleeding, or otherwise inappropriate if pretransfusion fibrinogen level was more than 1.0 g/L, pretransfusion fibrinogen level was not examined and posttransfusion fibrinogen level more than 1.5 g/L. Results: Most of the cryoprecipitate prescriptions were found to be inappropriate, which read 81.2% (95% confidence interval = 0.740, 0.880). Patients who underwent neurovascular surgery were the major recipient of cryoprecipitate, but majority of the prescription was found not appropriate. The decision to transfuse cryoprecipitate was found mostly appropriate when was guided by fibrinogen (52.2%), but the percentage dropped to 10.6% when pretransfusion fibrinogen test was not performed. Regrettably, only 19.7% of total cryoprecipitate were given based on pretransfusion fibrinogen level. PMID:27605853

    The occurrence of a coccidian parasite, Cryptosporidium, among birds in the Kuala Lumpur National Zoo was investigated in this study. A hundred bird fecal samples were taken from various locations of the zoo. Fecal smears prepared using direct smear and formalin ethyl acetate concentration technique were stained with modified Ziehl-Neelsen stain. Samples positive for Cryptosporidium with Ziehl-Neelsen stain were later confirmed using the immunofluorescence technique and viewed under the epifluorescence microscope. Six species of bird feces were confirmed positive with Cryptosporidium oocysts. They included Wrinkled Hornbill (Aceros corrugatus), Great Argus Pheasant (Argusianus argus), Black Swan (Cygnus atratus), Swan Goose (Anser cygnoides), Marabou Stork (Leptoptilos crumeniferus), and Moluccan Cockatoo (Cacatua moluccencis). These birds were located in the aviary and lake, with the Moluccan Cockatoo routinely used as a show bird. Results obtained in this study indicated that animal sanctuaries like zoos and bird parks are important sources of Cryptosporidium infection to humans, especially children and other animals.

    Human metapneumovirus (HMPV) is a recently discovered cause of viral respiratory infections. We describe clinical and molecular epidemiology of HMPV cases diagnosed in children with respiratory infection at University of Malaya Medical Centre, Kuala Lumpur, Malaysia. The prevalence rate of HMPV between 2010 and 2012 was 1.1%, and HMPV contributed 6.5% of confirmed viral respiratory infections. The HMPV patients had a median age of 1.6 years, and a median hospital admission of 4 days. The most common clinical presentations were fever, rhinitis, pneumonia, vomiting/diarrhoea, and bronchiolitis. Based on the partial sequences of F fusion gene from 26 HMPV strains, 14 (54%) were subgenotype A2b, which was predominant in 2010; 11 (42%) were subgenotype B1, which was predominant in 2012; and 1 (4%) was subgenotype A2a. Knowledge of the circulating subgenotypes in Malaysia, and the displacement of predominant subgenotypes within 3 years, is useful data for future vaccine planning.

    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.

    A review of malaria cases over a five year period from 1984-1988 at the University Hospital, Kuala Lumpur, Malaysia is presented. A total of 64 cases were recorded; 50% of which were due to Plasmodium falciparum, 40.6% were due to Plasmodium vivax, 6.2% due to Plasmodium malariae and 3.1% due to a mixed infection of Plasmodium falciparum and Plasmodium vivax. The breakdown of species type compared similarly with other studies conducted in the region. Of this total, sixteen cases were imported from Pakistan, India, Thailand, Indonesia, Sri Lanka, Vietnam, Madagascar and Mali. The presenting symptoms and the clinical findings were typical of a malaria infection. The main problem in the future will be the increase in imported cases of malaria.

    An Acute Pain Service (APS) was started in University Hospital, Kuala Lumpur by the Department of Anaesthesiology in October 1992 for more effective control of postoperative pain. The main modalities of treatment included patient controlled analgesia (PCA) using morphine or pethidine with PCA devises, epidural opiate analgesia (EOA) using tramadol or fentanyl/bupivacaine mixture and subcutaneous administration of morphine or pethidine. Five hundred and fifty-one patients were managed in the first year, with an overall patient satisfaction score of 83%. The majority (98.5%) of them were after abdominal or major orthopaedic surgery. Eighty per cent of patients scored < 3 on the verbal numeric pain scale, where 0 is no pain and 10 is the worst imaginable pain, on the first postoperative day. Nausea and vomiting was an unpleasant side effect in 20% of patients.

    A prospective collection of patients referred with a diagnosis of abdominal aortic aneurysm (AAA) to the Vascular Unit, Hospital Kuala Lumpur (HKL) between February 1993 to July 1995 were analysed. There were a total of 124 patients, with a 85 per cent (%) male preponderance. Malays formed the largest ethnic group contributing about 60%. The median age of the patients was 69 years (range 49-84). Emergency referrals and admission accounted for 46.8% of patients. Hypertension and ischaemic heart disease were the two most common co-morbid medical conditions. The number of patients who underwent surgery was only 56 (45.2%). Of this total, 34 were done electively with an operative mortality of 8.8% (3 pts). The operative mortality for emergency surgery was 59.1%. AAA is relatively common in the older age group, especially in men and it should be actively looked for, as elective surgery can be offered with acceptable morbidity and mortality.

    A prospective study of temperature drop in 141 normal term newborn infants delivered vaginally at the labour ward, University Hospital, Kuala Lumpur were studied. The effect of various manoeuvres on the temperature drop were also studied. They were randomized into 3 study groups, 63 cases where the babies were wiped with dry cloth alone, 37 cases where the babies were put into a plastic bag immediately after birth and lastly 41 cases where the babies were wiped with dry cloth and then inserted into a plastic bag. There was significant temperature drop in all the 3 groups maximum in the first 15 minutes and the fall continued for 1 hour after delivery (p less than 0.001). This shows that in an air-conditioned labour ward in a tropical country the temperature fall in newborn infants can be significant. This study also showed that plastic is a poor insulator against significant temperature drop.

    A retrospective review of rubella serological results carried out in the Virus Diagnostic Unit, University Hospital Kuala Lumpur (UHKL) from January 1993 to September 1999 showed the presence of rubella infection annually which appeared to increase periodically every two to three years. There was no statistical significant difference in the rubella positive rate between male and female population aged 14 to 48 years. Congenital rubella infections (CRI) occurred in babies delivered in UHKL yearly from 1993 to 1998 with an average incidence rate of 48 per 100,000 deliveries. Peaks of rubella cases appeared to be followed by an increase in incidence of CRI cases 6 to 9 months later. The study showed that only 50.8% clinically diagnosed rubella was confirmed by laboratory finding. This study also showed an increase of rubella activity for the months of July, August and September 1999 and this may herald an increase of CRI cases in the coming millennium.

    The effects of indoor environmental factors on respiratory illness were studied in 15017-12 year old school children in Kuala Lumpur. Exposure to mosquito coil smoke for at least three nights a week was independently associated with asthma and persistent wheeze. Passive smoking, defined as sharing a bedroom with an adult smoker, was independently associated with a chest illness in the past year. No relationships were found between exposure to kerosene stoves, wood stoves, fumigation mat mosquito repellents or aerosol insecticides and respiratory illness. Host factors predictive of at least one respiratory outcome included family history of chest illness, history of allergy, male sex, hospitalization in the neonatal period and low paternal education. With 95% confidence, avoidance of regular exposure to mosquito coil smoke and passive smoking could reduce the prevalences of persistent wheeze, asthma and chest illness by up to 29%. Measurements of lung function confirmed the validity of questions pertaining to wheezing and asthma in the study questionnaire.

    Critical incident reporting is a useful quality improvement technique for reducing morbidity and mortality in anaesthesia. This study analyses 93 cases in Kuala Lumpur Hospital from July 1995 to January 1997. The main incidents during anaesthesia in this study were airway incidents. While human error was identified as the main factor contributing to the occurrence of adverse incidents. Critical incident monitoring plays an important role in identifying potential problems, which may lead to disaster. The findings from this report of the anaesthesia incident monitoring study continued to indicate the occurrence of similar problems seen in an earlier report. The identification of common incidents can be used to identify risk factors and minimise repetition of such incidents.

    This study was done to determine the anthropometric measurement patterns of Malay children from wealthy families in Malaysia and to make a comparison with NCHS reference population. A population of 900 children aged between 3-12 years old from Taman Tun Dr Ismail, Kuala Lumpur (TDI), were examined but only 871 of them were eligible for the study. Weight, height, mid-arm circumference and skin fold thickness were measured. The increment pattern of anthropometric measurements of TDI children was quite similar to NCHS except for having a lower median weight for age and height for age. There was prepubescent increase in skin folds thickness in both sexes, followed by a midpubescent decrease and a late pubescent increase. The study indicated that Malay children from a wealthy background have growth rates comparable to children in the West, hence NCHS percentile charts are suitable as a reference for comparing the nutritional status of Malay children in Malaysia.

    In this retrospective study, 81 patients were diagnosed to have deep vein thrombosis (DVT) at the University Hospital, Kuala Lumpur over a ten year period from 1977 to 1986. Fifty-six patients had their DVT confirmed by venograms. The left side was affected in 79.5% of venographically proven cases of DVT of the lower limbs above the popliteal vein. The incidence of clinically apparent DVT following surgery was 0.21 per 1,000 operations. The incidence of pregnancy-related DVT was 0.039%. DVT was 3 times more frequent in the puerperium than in the antenatal period. The overall incidence of symptomatic pulmonary embolism was 13.6% of the cases of DVT.

Malays constituted 27.6%, Chinese 29.8%, Indians 9.7%, Indonesians 16.4% and other foreigners 16.4%. Therefore, of the total number of cases, foreigners constituted 32.8% (44) of all the malaria cases admitted to UHKL. Fifteen of these foreigners had chloroquine-resistant strains of malarial parasites. Three species of malaria were reported of which Plasmodium falciparum constituted the most (46.3%) (80% of these developed resistance to chloroquine). Plasmodium vivax was confirmed in 44.8% (10% of these developed resistance to chloroquine) and there was only one case of Plasmodium malarie infection.

    Aerosampling using Rotorod samplers was conducted in the Institute for Medical Research, Kuala Lumpur, Malaysia, from December 1991 to November 1993. Samples were collected twice a week between 10.00 hours to 12.00 hours. Rods were stained and examined microscopically. A total of 8 and 20 types of pollens and mold spores were collected, respectively. More mold spores were collected than pollens. Grass pollen constituted more than 40 percent of total pollen counts. Gramineae pollen counts peaked in March and September. The most abundant mold spore was Cladosporium followed by Rust, Nigrospora, Curvularia and Smut. Cladosporium counts peaked in February and August. Rust counts peaked in June and December whereas counts for Nigrospora peaked in February and October. Highest counts of Smut were recorded in March and October. Curvularia counts peaked in January, June and September.

    4 maternal deaths from abortion that took place during the 6-year period from March 1968 to February 1974 in the University Hospital, Kuala Lumpur are reviewed with focus on the avoidable causes and preventive aspects. The total maternal deaths from all causes for the 1699 admission was 13. The mortality rate from abortion during this period was 0.241/1000 pregnancies. The number of abortion cases admitted into the hospital during the 6-year period increased steadily. Of the 4 abortion deaths, 3 patients admitted to attempts at inducing abortion. 1 patient denied having induced abortion, although her husband felt that it could have occurred. All 4 cases of abortion deaths occurred in patients with septic abortions and were, theoretically, avoidable deaths. It is most important to prevent sepsis in a case of abortion. Patients with endotoxic shock are often given intravenous steroids in pharmacological doses every 4-6 hours.

    Knowledge about contraception was examined in relation to selected socioeconomic variables. A total of 2567 currently married women aged 15-49 years residing in Kuala Lumpur and Petaling Jaya were interviewed. The majority of the women knew of at least 1 contraceptive method. An index termed Contraceptive Knowledge Score (CKS) was used to measure the level of knowledge about contraception. The CKS achieved differed significantly by age, area of residence and ethnic group. The other socioeconomic variables significantly associated with CKS are schooling, occupation, income, childhood residence and age at marriage. These relationships persisted even after adjusting for differences in age, ethnicity and area of residence. Overall the CKS attained have a wide range and there is no significant difference of the mean CKS attained, between users and non-users of contraceptives.

    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.

    The clinical, haematological and biochemical profiles of all domestic and imported malaria cases admitted to the Hospital Kuala Lumpur were analysed. The most common malaria types were Plasmodium falciparum (39.5%) and Plasmodium vivax (42%). The most common patient type was men aged 29-40 years (reflecting the high mobility of this group, many of whom were illegal immigrants). Misdiagnosis on admission was frequently due to the variable clinical presentation of the disease and the difficulties of obtaining an accurate history. Associated haematological abnormalities were common. Chloroquine resistance was diagnosed in four P. falciparum patients and in one P. falciparum/vivax patient. Overall, imported malaria did not seem more severe than domestic. The three patients with cerebral malaria survived. One patient died of acute liver failure. The large influx of illegal immigrants to Malaysia has resulted in a surge in malaria infection; illegal immigrants remain a source of chloroquine resistance.

    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. PMID:25887064

    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%). Nevertheless, there were marked differences in prevalence rates between sites and hosts. The influence of extrinsic (year, season and site) and intrinsic (species, sex and age) factors affecting infracommunity structure (abundance and prevalence of infection) and measures of component community structure were analyzed. Conclusions Since at least two species of rat borne helminths in Kuala Lumpur have the potential to infect humans

    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.

    Breast cancer is the most common female cancer and the commonest cause of death due to cancer for women in Malaysia. This study was performed to identify the relationship with lifestyle factors. A case-control study was conducted among females with breast cancer who came for treatment to the Breast Clinic Hospital Kuala Lumpur in July until September 2004. A total of 203 female patients were recruited as cases along with 203 patients who attended the Outpatient Clinic, Hospital Kuala Lumpur during the study period as the controls. The study showed women who did not exercise regularly to have four times higher risk (adjusted odds ratio is 3.49, 95% CI is 1.84 to 6.62) compared to those who exercised regularly. Women with a high fat diet were also at elevated risk (adjusted odds ratio 3.84, 95% CI is 1.20 to 12.34) compared to those consuming a low fat diet. Women without breast cancer generally had a longer duration of lifetime lactation with a median of thirty-three months compared to women with breast cancer (twenty months, p<0.05). Women who did not take oral contraceptive pills but had breast-fed their child have a 56.0% lower risk (crude odds ratio 0.44, CI is 0.22 to 0.87) compared to women who did not take oral contraceptive pill and also did not breast-feed their child. If they had breast fed for thirteen months and above, they faced a 61.0% lower risk (crude odds ratio 0.39, 95% CI is 0.17 to 0.87). There was a significant inverse trend for lifetime lactation and breast cancer risk. In conclusion certain life styles of women are associated with a higher risk of breast cancer development. Therefore, the promotion of a healthy life style should be emphasized.

    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.

    From January 1980 to August 1992, there were 125 deaths occurring in the operating theatre at the University Hospital Kuala Lumpur. Out of these 125, six were judged to have been mainly 'due to anaesthesia.' In the same time period, there were a total of 155,000 anaesthetics given in the hospital. This gives an anaesthetic death rate (in the operating theatre) of six out of 155,000 or 0.39:10,000.

    The World Health Organization (WHO) recommend that all donated blood are to be screened for at least three viral infections [human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV)]. The National Blood Centre, Kuala Lumpur (NBCKL) aims to reduce transfusion transmitted infections (TTI) as it still remains as one of the major risk for blood transfusion. A cross sectional study was conducted at the National Blood Centre, Kuala Lumpur from 1st January 2009 to 31st June 2010. Data from 581,020 donors were analyzed from year 2004 to 2008. All data were retrieved from NBCKL Blood Bank Information System (BBIS). A total of 201 repeat donors were included in the study based on the inclusion criteria but only 132 repeat donors agreed to participate. Information on sociodemographic, risk factors, knowledge of donors and high risk behavior were extracted from standardize questionnaire. Data were analyzed using SPSS version 14.0. The aim of this study was to determine the predictors of the seropositive infectivity among repeat blood donors at the NBCKL. The results showed Syphilis accounts for the highest and increasing seroconversion rate among other infections from 20.83 % in year 2004 to 44.6 % in year in year 2008. HIV and HCV infection also showed increasing seroconversion rate in 5 years' time from 6.41 % in year 2004 to 17.54 % in year 2008 and 4.8 % in year 2004 to 5.94 % in year 2008 respectively. However, HBV infection alone showed a decreasing seroconversion rate from 20.83 % in year 2004 to 10.4 % in year 2008. Level of donors' awareness regarding high risk factors (activities or behaviour) can lead to higher risk of TTI with significant p value in this predictors model(p < 0.05). Repeat blood donors with high risk activities are more likely to have seropositive results for HBV, HIV and Syphilis. This study found that the frequency of HCV seropositivity is higher among lapsed donor. Socio demographic factors such as male and

    A clinical trial was carried out on the levonorgestrel-containing subdermal contraceptive implant to evaluate its efficacy and acceptability among Malaysian women. The study recruited 121 women in and around the Kuala Lumpur Federal Territory over a 13-month period (March 1986-March 19870 and followed regularly for 2 years at intervals of 3, 6, 12, and 24 months. The acceptors consisted of 53.7% Malays, 24.8% Indians, and 21.5% Chinese. 81% of the selected females were between 20-34 years in age (mean=30). The average parity was 3.9 children; 81.8% reported that they did not want to have a child in the he next 3 years. In the last 6 months, 45.5% of the study group had used the oral contraceptive pills, 15.7% had used the intrauterine contraceptive device, and 17.4% had not employed any method. The results showed that the subdermal implant Norplant (R) is effective and safe. The gross cumulative continuation rate was 93.8 at 6 months, 88.2 at 12 months, and 72.2 at 24 months. Within the 24 month period, 26 terminations occurred as a result of pregnancy (n=1), menstrual problems (n=9), medical reasons (n=12), and personal reasons (n=4). the gross cumulative termination rate/100 women for pregnancy was 0 at 12 months and 1.7 at 24 months. Major side effects include menstrual problems, weight gain, dizziness, and headache. After 1 year, 13.3% of the cases (n=2) had the implant removed. The acceptability of the method among our women in 4 clinics around Kuala Lumpur and other Norplant (R) studies in other countries is comparable to the intrauterine devices among Malaysian women; the termination rate for accidental pregnancy is lower than that of IUD. The device is easy to administer in a small clinical set-up though it requires personnel specially trained in the surgical techniques; 86.0% of the acceptors reported complication-free insertion.

    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.

    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.

    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.

    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.

    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 resistance status towards permethrin among the laboratory strain, the permethrin-selected strain and four field strains of Culex quinquefasciatus collected in Kuala Lumpur, Malaysia was determined using three standard laboratory methods: WHO larval bioassay, WHO adult bioassay and biochemical microplate assay. Cx. quinquefasciatus permethrin-selected strain larvae were the least susceptible to permethrin with a resistance ratio of 47.28-folds, whereas all field strain larvae of the same species were tolerant to permethrin with resistance ratios of more than 3-folds. In contrast, in adult stage, the permethrin exposed permethrin-selected strain (resistance ratio = 1.27) was found to be more susceptible to permethrin than all permethrin-exposed field strains (resistance ratios = 2.23-2.48). Complete mortalities for all strains of Cx. quinquefasciatus adults proved the effectiveness of the synergist; piperonyl butoxide (PBO). For the biochemical microplate assay, the reduction of the mean optical density of elevated oxidase activity of three field strains upon exposure to PBO confirmed the association between oxidase activity and permethrin tolerance. On the other hand, irregular patterns of the mean optical density of elevated oxidase activity in the laboratory strain, permethrin-selected strain and Jalan Fletcher strain illustrated the gene variation within these mosquito colonies as well as the involvement of other enzyme activities in the permethrin resistance occurred.

    Long-term measurements (2004-2011) of PM10 (particulate matter with an aerodynamic diameter <10 μm) and trace gases (carbon monoxide [CO], ozone [O₃], nitrogen oxide [NO], oxides of nitrogen [NO(x)], nitrogen dioxide [NO₂], sulfur dioxide [SO₂], methane [CH₄], nonmethane hydrocarbon [NMHC]) have been conducted to study the effect of physicochemical factors on the PM10 concentration. In addition, this study includes source apportionment of PM10 in Kuala Lumpur urban environment. An advanced principal component analysis (PCA) technique coupled with absolute principal component scores (APCS) and multiple linear regression (MLR) has been applied. The average annual concentration of PM10 for 8 yr is 51.3 ± 25.8 μg m⁻³, which exceeds the Recommended Malaysian Air Quality Guideline (RMAQG) and international guideline values. Detail analysis shows the dependency of PM10 on the linear changes of the motor vehicles in use and the amount of biomass burning, particularly from Sumatra, Indonesia, during southwesterly monsoon. The main sources of PM10 identified by PCA-APCS-MLR are traffic combustion (28%), ozone coupled with meteorological factors (20%), and wind-blown particles (1%). However, the apportionment procedure left 28.0 μg m⁻³, that is, 51% of PM10 undetermined.

    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.

    Prior to 1993, bone marrow transplantation for adult patients was not available in Malaysia. Adult allogeneic bone marrow transplantation commenced in Malaysia when the first transplant was conducted at the University Hospital, Kuala Lumpur on 2 November 1993. Up till July 1995, 10 adult bone marrow transplants had been conducted at the University Hospital. Five patients had acute myeloid leukaemia in first remission, 4 had chronic myeloid leukaemia and 1 had acute lymphoblastic leukaemia in first partial remission. The age range of patients at the time of transplant is 16-40 years (mean 25.5 years). All patients engrafted successfully and the survival for the first 100 days post-transplant is 90%. One patient demonstrated haematological relapse post-transplant but achieved remission with donor buffy-coat infusion. The mean drug cost incurred was RM28,269 for the first 100 days. Locally available adult allogeneic bone marrow transplantation is safe, affordable and has comparable results with reputable overseas transplant centres.

The prevalence of asthma (defined as persistent wheeze and/or doctor-diagnosed asthma) was 13.8%. 4.3% experienced at least one episode of chest illness that resulted in inactivity for at least 3 days in the previous year. The mean age of commencement of symptoms in the doctor-diagnosed asthma group was 2.75 years. The prevalence of chronic cough and/or phlegm and persistent wheeze were highest among Indian children (p less than 0.05). More Malays had been diagnosed as having asthma than the other ethnic groups but the differences were not statistically significant. The patients' fathers' low levels of education were associated with chronic cough and/or phlegm (p less than 0.05) but not with other complaints. Asthma was significantly more common among boys than girls. No age differences were noted. Further analysis showed that persistent wheeze and doctor-diagnosed asthma were associated with increased likelihood of other respiratory illnesses or doctor-diagnosed allergy before the age of 2 years.

    The ascaridoid nematode of cats from Kuala Lumpur, Malaysia, previously identified morphologically as Toxocara canis, was characterized using a molecular approach. The nuclear ribosomal DNA (rDNA) region spanning the first internal transcribed spacer (ITS-1), the 5.8S gene and the second internal transcribed spacer (ITS-2) was amplified and sequenced. The sequences for the parasite from Malaysian cats were compared with those for T. canis and T. cati. The sequence data showed that this taxon was genetically more similar to T. cati than to T. canis in the ITS-1, 5.8S and ITS-2. Differences in the ITS-1 and ITS-2 sequences between the taxa (9.4-26.1%) were markedly higher than variation between samples within T. canis and T. cati (0-2.9%). The sequence data demonstrate that the parasite from Malaysian cats is neither T. canis nor T. cati and indicate that it is a distinct species. Based on these data, PCR-linked restriction fragment length polymorphism (RFLP) and single-strand conformation polymorphism (SSCP) methods were employed for the unequivocal differentiation of the Toxocara variant from T. canis and T. cati. These methods should provide valuable tools for studying the life-cycle, transmission pattern(s) and zoonotic potential of this parasite.

    Nutrient intake was surveyed by the total food duplicate method in 49 adult ethnically Malay women (at the ages of 18 to 47 years and mostly at 30-39 years) working in Kuala Lumpur, Malaysia. Simultaneously, hematological examinations, serum biochemistry, anthropometry and clinical examination were conducted. Nutrient intakes were estimated in reference to the weight of each food item and the standard food composition tables. Lunch was the most substantial meal of the day with rice as a staple food. Compared with the Recommended Dietary Allowance (RDA) values, daily intakes of energy (1,917 kcal as an arithmetic mean), protein (62.2 g), vitamin B1 (0.83 mg) and vitamin B2 (1.18 mg) were sufficient, but intakes of minerals [i.e., calcium (347.8 mg) and iron (12.5 mg)] and some vitamins [i.e., vitamin A (equivalent to 627 micrograms retinol) and niacin (7.84 mg)] were less than RDA. When evaluated on an individual basis, the prevalence of those who took less than 80% RDA was highest for iron (92%), followed by niacin (80%), calcium (57%) and vitamin A (57%). The presence of 7 hypohemoglobinemia cases may be related to the insufficient iron intake. Overweight cases (14 women) were also detected, the prevalence of which increased at advanced ages. Lipid intake was rather high (28% of total food on energy basis), for which the major source was plants with limited contribution from fish/shellfish.

    Available evidence has shown that the type of abuse perpetrated on children depends considerably on the social and other factors inherently faced by these children. A total of 119 cases of physical abuse was detected by the Suspected Child Abuse and Neglect (SCAN) Team of General Hospital, Kuala Lumpur in 1991. Eighty-two cases were categorized as mild and 37 as severe. The average age of those mildly abused was 7.9 years, for those severely abused the average age was 4.2 years. The perpetrators of those mildly abused were often their own parents. However, among those severely abused, the child-minder was the most frequent abuser. Ninety-two of all cases were in families of social classes IV and V. In 47 cases, there was definite evidence of family disharmony or disruption. Among the 37 severely abused, the parents were either divorced or separated in 14 cases. There was a personality disorder in seven of the cases. Six of the abusers were also using drugs and nine were alcoholics. This paper shows that, even in a developing country, the social milieu is important in the type of abuse inflicted.

    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.

    Provision of quality care, service and blood products to patients while containing costs and the amount of blood used should be the aim of every blood bank. Therefore a prospective audit was carried out over three months to determine how efficiently blood was being used in elective surgery in the University Hospital, Kuala Lumpur. Every case with blood crossmatched was monitored to determine the amount transfused and the posttransfusion haemoglobin level. Overcrossmatching of varying degrees was noted in almost all surgical procedures and overtransfusion in 45.5% of patients transfused. The rate of case postponement was 18.1%. These indicate inefficient utilization of blood and other resources. The transfusion index (TI) and range of units transfused were calculated for each procedure. They can be used as indicators of blood requirement and potential severity of hemorrhage. Suggestions to improve efficiency of blood utilization include the introduction and ongoing monitoring of guidelines on crossmatching and transfusion based on the data obtained here, by the hospital blood transfusion committee; the "group, screen and hold" practice for surgical procedures with high crossmatch transfusion ratios, low transfusion indices and a small range of units transfused could also be adopted.

    A hospital based retrospective study of amoebiasis was carried out for a ten-year period at the University Hospital, Kuala Lumpur. Of the 51 cases traced, 30 (59%) had amoebic dysentery, 20 (39%) were amoebic liver abscess (ALA) and one patient had both conditions. Entameoba histolytica trophozoites were identified in 13 (43%) of the amoebic dysenteric stools and 9 (30%) from biopsy. Of the 20 (39%) ALA cases, only one showed parasites in the stool and biopsy. Majority of the patients with dysentery were Malays while Chinese comprised 40% with ALA. Males predominated overall with a male female ratio of 3:1, while for ALA it was 9:1. Most of ALA were single (71.4%) and were localised in the right lobe. The majority of the patients were unemployed. Eighty three percent (83%) of the patients presented with diarrhoea or dysentery followed by abdominal pain while those with ALA had fever, chills, rigors and pain in the right hypochondrium. Eighty percent of the ALA cases showed hepatomegaly. All patients responded to treatment with metronidazole.

    A retrospective study was conducted in 130 patients who underwent replantation or revascularization of 195 amputations in Hand and Microsurgery Unit Hospital Kuala Lumpur from 1990 to 1995. There were 130 patients with 195 amputations in the duration of 6 years study, which were mainly males (111 patients, 85.4%). The commonest age group involved was 19-25 years old (49 cases, 63.7%). There were 146 complete amputations replanted and 49 cases of incomplete amputations were revascularized. The commonest part involved was thumb and index finger (23% of cases each) and majority was caused by industrial accident (60.8%). However in pediatric age group home accident was the leading cause of the amputation (93.8%). The overall survival rate for the amputation was 65.6%. Revascularization had a better survival rate (77.6%) than replantation (61.6%). A clean cut wound and ischaemic time less than 12 hours gave better survival rate. However, there was no significant different chance of survival on distribution of injured parts and ischaemic time (< 12 hours).

    Abstract Peripheral blood and 24-h total food duplicate samples were obtained from 49 adult Malay women in Kuala Lumpur, Malaysia, in July, 1995. Samples of boiled and uncooked (raw) rice were also collected from the subjects. The blood samples, homogenates of each food duplicates and rice samples (both cooked and raw) were digested by heating in the presence of mineral acids, and the digests were subjected to analysis for cadmium (Cd) and lead (Pb) with a system composed of a fully automated liquid sampler, a graphiie furnace atomic absorption spectrometer and a data processor. The geometric mean metal concentrations in blood were 0.71 ng Cd per ml and 45.6 ng Pb per ml, and the dietary metal intakes were 7.31 μg Cd per day and 10.1 μg Pb per day. The metal intake via rice accounted for 53% and 13% of total dietary intake of cadmium and lead, respectively. When the absorption from the air and foods was compared, the cadmium burden came almost exclusively from foods, whereas the lead burden came both from air (44%) and foods (56%).

    This study documents the prevalence of Hepatitis B serological markers among STD patients who have had multiple sexual partners in Kuala Lumpur, Malaysia, and compares the rates with those of a sample of the population with single or no sexual partners. A total of 336 Chinese STD patients (multiple partners group) and 234 Chinese control subjects (non-multiple partner group) were screened. Those with a history of blood transfusion or parenteral drug abuse had been excluded from the study, and all study subjects were heterosexuals. The overall carrier rate was 9.2% for the multiple partner group (MP group) and 6.8% for the non-multiple partner group (NMP group). Infection rates were 64.3% for the MP-group and 38.9% for the NMP group. After adjustments for age and sex, there was no significant difference in carrier rates between the two groups, but infection rates were significantly different with the MP group, being 3.2 times more likely to acquire infection than the NMP group. The study concludes that in heterosexuals, those with multiple sexual partners have increased chances of acquiring HBV infection.

    Stool samples from healthy children mainly of the low income group aged 0 to 7 years of age from five Maternal and Child Health Centres in Kuala Lumpur were obtained for isolation of enteroviruses. The specimens were collected before and after the mass vaccination given in the face of polio type 1 epidemic which started in October, 1971. The prevelance rate of enteroviruses was 11.9% (3.0% polioviruses, 8.9% non-polio enteroviruses) before the vaccination and essentially the same after. Coxsackie A viruses predominated over the other enteroviruses in the pre- and post-vaccination phases. The highest isolation rate of enteroviruses was observed in children 0 to 2 years age. No significant differences in distribution by sex, race and month were noted. A sharp fall in the prevalence rates of total enteroviruses and polioviruses was noted shortly after the mass vaccination campaign However, the rates reverted to the pre-vaccination state during the next successive years.

    Between 1987 to 1995, a total of 334 patients infected with HIV were treated at the Hospital Kuala Lumpur. There were 159 Malays, 108 Chinese, 64 Indians, and 3 from other ethnic groups. Three hundred and twenty-one (96.1%) of these individuals were males and 262 (65.9%) were between the ages of 26-45 years. Intravenous drug users made up 77% (256) of the attributable risk behaviour from the group although many of them also had added risk behaviours like heterosexual activity with multiple partners (50 patients), tattoos (7 patients), homosexual practice (4 patients) and previous transfusions (3 patients). The others acquired their infection through heterosexual promiscuity (59 patients), homo/bisexual activity (7 patients), previous transfusion (5 patients) and tattoos (1 patient). Sixty-six patients (all males) had since progressed to full blown AIDS and 10 have died. The two commonest AIDS-defining events were tuberculosis infection and Pneumocystic carinii pneumonia occurring in 37 (56%) and 15 (22.7%) of patients respectively. Forty-one patients with AIDS presented for the first time with their AIDS-defining infections. The mean CD4 count of the patients when they progressed to AIDS was 130/mm3. The mean time for progression from "known" seropositivity to AIDS was 2.42 years. These results suggest that Malaysians infected with HIV are not coming forward for treatment until they are in the advanced stage of the disease.

    A prospective study was carried out in the Maternity Hospital, Kuala Lumpur in 1989 to determine the morbidity and mortality of infants of diabetic mothers. Out of 24,856 neonates born during the study period, 54 neonates (2.2 per 1000 livebirths) were born to mothers who were diagnosed to have diabetes mellitus before the current pregnancy or who had impaired glucose tolerance test during the current pregnancy. Almost a third (29.6 percent) of these infants of diabetic mothers had birthweight of 4000 grams and above, and 37.0 percent of the 54 babies were large-for-gestational age. Hypoglycemia occurred in 9/54 (16.7 percent) of the neonates, respiratory distress syndrome in 5/54 (9.3 percent), shoulder dystocia in 7/54 (13.0 percent), and congenital abnormalities in 4/54 (7.4 percent). Three (5.6 percent) neonates died during the neonatal period. The results of this study suggest a need to intensify control of maternal diabetes mellitus during pregnancy in order to reduce the rates of morbidity and mortality of their infants.

    Fifteen patients underwent surgery for cardiac tumours in General Hospital Kuala Lumpur between October 1984 and June 1989. Twelve of the patients had cardiac myxomas and underwent excision under cardiopulmonary bypass. Two patients had sarcoma, of which one was excised. The other was inoperable. Another patient had a metastalic malignant melanoma which was inoperable. Of the patients 10 were female and five male. Their ages ranged from 16 to 60 years. All were symptomatic and the commonest mode of presentation was exertional dyspnoea and palpitations. Two presented with cerebral embolisation. The three patients with malignant tumours had constitutional symptoms at the time of surgery. All patients had echocardiography pre-operatively to confirm the diagnosis of cardiac tumour. Only one patient underwent preoperative cardiac catheterisation and angiography. The surgical approach in all patients was through a median sternotomy and all except one were operated under cardiopulmonary bypass. There was no intraoperative embolisation. There was one perioperative death. Fourteen patients were followed up for periods ranging from one to 44 months. Three patients with malignant cardiac tumours died. One had recurrence of myxoma 21 months after the initial surgery. We conclude that excision of cardiac myxomas carry a very small risk following which patients have good prognosis. Malignant tumours carry a bad prognosis. From our experience, we conclude that echocardiography is an extremely accurate tool in the diagnosis of cardiac tumours.

    A review of gestational trophoblastic disease diagnosed at the Department of Pathology, University Hospital, Kuala Lumpur from January 1989 to December 1990 using established histological criteria showed 25 complete hydatidiform moles (CHM), 11 partial hydatidiform moles (PHM), 1 invasive mole and 2 choriocarcinoma. The ages of the patients with CHM ranged from 21 to 43 years (mean = 28.5 years) and PHM 20 to 33 years (mean = 27.5 years). The invasive mole occurred in a 42-year-old Malay woman. The two patients with choriocarcinoma were both Chinese and 41 and 46-years old respectively. During the same period, 1,062 non-molar abortions and 13,115 births, inclusive of livebirths and stillbirths were recorded at the University Hospital. The incidence rate of hydatidiform moles was thus estimated to be 1:384 pregnancies. PHM constituted 30% of all molar pregnancies. Hydatidiform moles occurred among the Malays, Chinese and Indians at the rate of 2.43, 2.66 and 3.29 per 1,000 pregnancies respectively. It appears that hydatidiform molar pregnancy has the highest prevalence among the Indians, a finding similar to an earlier Singapore study.

    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.

    The objective of this paper is to assess the perception of bodyweight status among the office workers in two government departments in Kuala Lumpur. A total of 385 Malay workers aged between 18 to 55 years were randomly selected from the Prime Minister's Department and the Ministry of National Unity and Community Development. The weights and heights of all subjects were measured and their Body Mass Index (BMI) determined. In this study, obesity is defined as individuals having 25 kg/m2. A questionnaire was prepared to obtained information on socioeconomic status, health aspects, dietary intakes, activity levels and perception on bodyweight status. The study revealed a high prevalence of obesity (38.1 %) and among the obese subjects, 21.7 % perceived themselves as having normal weight. The normal weight and underweight subjects perceived themselves as obese (33.5 % and 6.3 % respectively). A small percentage (5.7 %) of the obese individuals who perceived themselves as obese did not wish to Lose weight. In contrast, 9.7 % of the normal weight subjects who perceived themselves as having normal weight wanted to lose weight. A third person's perception on the subjects' bodyweight status is significantly associated with the subjects' bodyweight status (P<0.05). Among the obese subjects, more men (32.3 %) perceived themselves as having normal weights as compared to the women (12.3 %). This implies that women are more aware of their bodyweight status as compared to the men.

    A total of 5,995 (7.8% of all 7- to 10-year-old primary schoolchildren in Kuala Lumpur), randomly selected from 166 schools (97.6% of all schools), were measured for their weight and height. The analyses of all weight and height data, including the cutoffs used for defining stunting, underweight, and wasting and for thinness and overweight, were carried out as recommended by the World Health Organization (WHO). The prevalances of stunting (height-for-age Z score < -2 SD), underweight (weight-for-age Z score < -2 SD) and wasting (weight-for-height Z score < -2 SD) among all the children studies were 6.7%, 7.1%, and 4.5%, respectively. Undernutrition among boys was more serious than among girls according to all three indicators. Because it was not possible to analyze the weight-for-height data for most of the children above 8.5 years of age, body mass index (BMI)-for-age was used to determine the prevalences of thinness and overweight for all the children. Based on the reference data, the prevalence of overweight (at or above the 95th percentile) was 9.7% and 7.1% for boys and girls, respectively, and 8.4% overall. PMID:11975368

    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.

    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.

    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.

    Background: There is growing interest in research on patient satisfaction with healthcare provider (HCP) communication as a measure of healthcare quality and HCPs’ communication competency. This study aimed to determine the levels of patient satisfaction with healthcare provider-patient communication (HCP-PC) and its associated factors at the outpatient clinic at Hospital Kuala Lumpur. Methods: A cross-sectional study was conducted on a convenience sample in July 2012 using self-administered questionnaires for the data collection. Both overall and domain-specific satisfaction were measured, with the three domains being exchanging information (EI), socio-emotional behaviour (SB), and communication style (CS). Results: The findings show that 92.8% of the 283 respondents were satisfied with overall HCP-PC, 89.5% with EI, 91.3% with SB, and 72.2% with CS. Satisfaction was statistically higher among Malays for CS and higher among those with low education and poor health for EI, SB and CS. EI and overall communication satisfaction were also higher among patients who reported short wait times, and patients who were in gender concordance with their HCPs showed higher SB satisfaction. Conclusion: Basic and continuous communication skills training and patient activation programs should be established to increase patient satisfaction. Health information technology use should be actively promoted to allow for structured and standardised information exchange between HCPs and patients. PMID:26715897

    The spread of HIV infection into Malaysia is estimated to have occurred in the early 1980's. The first case of AIDS was reported here in 1986. As of March 31, 1994, the numbers have increased to 8049 HIV positive individuals detected in the country. The risk behaviours among those tested positive were intravenous drug use in 77.2%, sexual transmission in 4.5%, while the remainder are still under investigation. Pediatric AIDS constitutes 0.2% of positives. The high prevalence among intravenous drug users (IVDU) is likely to be due to mandatory testing for HIV upon entry to rehabilitation centres. The trend of HIV infection in this country seems to be highest amongst the intravenous drug users. The increasing number of HIV infected prostitutes and heterosexuals in our population is worrying. Since 1986, a total of 104 HIV positive individuals have been treated at the University Hospital, Kuala Lumpur, Malaysia. Of these, 25 have died and of those still alive, 5 have symptomatic disease. The most common AIDS-defining illness is Pneumocystis carinii pneumonia. Education programmes have been developed targeting the various high risk groups and the general population.

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.

    Long-term measurements (2004-2011) of PM10 (particulate matter with an aerodynamic diameter <10 μm) and trace gases (carbon monoxide [CO], ozone [O₃], nitrogen oxide [NO], oxides of nitrogen [NO(x)], nitrogen dioxide [NO₂], sulfur dioxide [SO₂], methane [CH₄], nonmethane hydrocarbon [NMHC]) have been conducted to study the effect of physicochemical factors on the PM10 concentration. In addition, this study includes source apportionment of PM10 in Kuala Lumpur urban environment. An advanced principal component analysis (PCA) technique coupled with absolute principal component scores (APCS) and multiple linear regression (MLR) has been applied. The average annual concentration of PM10 for 8 yr is 51.3 ± 25.8 μg m⁻³, which exceeds the Recommended Malaysian Air Quality Guideline (RMAQG) and international guideline values. Detail analysis shows the dependency of PM10 on the linear changes of the motor vehicles in use and the amount of biomass burning, particularly from Sumatra, Indonesia, during southwesterly monsoon. The main sources of PM10 identified by PCA-APCS-MLR are traffic combustion (28%), ozone coupled with meteorological factors (20%), and wind-blown particles (1%). However, the apportionment procedure left 28.0 μg m⁻³, that is, 51% of PM10 undetermined. PMID:26030827

    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.

    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. PMID:16963785

    Public transportation serves people with mobility and accessibility to workplaces, health facilities, community resources, and recreational areas across the country. Development in the application of Geographical Information Systems (GIS) to transportation problems represents one of the most important areas of GIS-technology today. To show the importance of GIS network analysis, this paper highlights the determination of the optimal path between two or more destinations based on multi-mode concepts. The abstract connector is introduced in this research as an approach to integrate urban public transportation in Kuala Lumpur, Malaysia including facilities such as Light Rapid Transit (LRT), Keretapi Tanah Melayu (KTM) Komuter, Express Rail Link (ERL), KL Monorail, road driving as well as pedestrian modes into a single intelligent data model. To assist such analysis, ArcGIS's Network Analyst functions are used whereby the final output includes the total distance, total travelled time, directional maps produced to find the quickest, shortest paths, and closest facilities based on either time or distance impedance for multi-mode route analysis.

    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.

    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.

    Five local Malaysian patients with clinical manifestations consistent with lymphatic filariasis were referred to our medical centre between 2003 and 2006. Although no microfilariae (mf) were detected in their nocturnal blood samples, all were diagnosed to have lymphatic filariasis on the basis of clinical findings and positive serology results. PCR on their blood samples revealed that two of the patients were infected with Brugia pahangi, an animal filarial worm hitherto not known to cause human disease in the natural environment. All the patients were successfully treated with anti-filarial drugs: four patients were treated with a combination of diethylcarbamazine (DEC) and albendazole, and one with doxycycline. Four of them were residents of Petaling Jaya, a residential suburbia located 10 km southwest of Kuala Lumpur city, Malaysia. The fifth patient was a frequent visitor of the suburbia. This suburbia has no history or record of B. malayi infection. The most likely vector of the worm was Armigeres subalbatus as extensive entomological surveys within the suburbia revealed only adult females of this mosquito species were infected with B. pahangi larvae. Wild monkeys caught in the suburbia were free from B. pahangi mf, but domestic cats were mf positive. This suggests that infected cats might be the source of the zoonotic infection in the suburbia.

    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.

    Using the tools developed for statistical physics, we simultaneously analyze statistical properties of the Jakarta and Kuala Lumpur Stock Exchange indices. In spite of the small number of the data used in the analysis, the result still shows the universal behavior of complex systems previously found in the leading stock indices. We also analyze their properties before and after the crash caused by the monetary crisis. To locate the time position when the crash started we use the Omori law. We found that after the crash both stocks do not show a same statistical behavior. The impact of currency controls is observed in the distribution of the index returns.

    This is a study of 54 intravenous drug user's (IVDUs) with infected pseudoaneurysms undergoing ligation and debridement at the Vascular Unit, Hospital Kuala Lumpur (HKL) from February 1993 to February 1996. The median age was 37 years with a male preponderance (53:1). Chinese form the largest ethnic group with 57.4% of the cases. Staphylococcus aureus was the most common organism cultured. Human immunodeficiency virus (HIV) positive cases numbered 21 (38.9%). Four of the patients had to have an above-knee amputation after surgery. Simple ligation and debridement of all necrotic tissue is an acceptable mode of therapy in these patients with low amputation rates.

    Plateletpheresis is a method used to remove platelet from the body either from random volunteer donors, patient's family members or HLA matched donors. A cross sectional study was carried out on 59 plateletpheresis donors aged between 18 and 55 years at National Blood Center (NBC), Kuala Lumpur. We compared the blood parameters before and after plateletpheresis and we found that the platelet count, FVIII, fibrinogen and thrombophilia markers anti-thrombin (AT), protein C and protein S were significantly reduced (p<0.05) with prolonged PT and APTT. There were significant changes in blood coagulation parameters but it is within acceptable range.

    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. PMID:26448645

    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. PMID:25964827

    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.

    The results of 109 primary total hip arthroplasties in 92 patients performed in Hospital Kuala Lumpur from January 1987 to December 1996 were reviewed after a mean follow-up of 30.8 months. There were 22 males and 70 females with the average age of 49.9 years (range 19 to 94 years). Chinese females comprised the largest group of patients (52.2%). Avascular necrosis was the most common diagnosis (33.1%) followed by hip dysplasia and primary osteoarthritis (17.4%). The procedure was performed more on the right hip (64.2%) compared to the left (35.8%). All patients received prophylactic antibiotics but none were given deep vein thrombosis prophylaxis. The Charnley prosthesis was most commonly used and the majority of the arthroplasties were cemented (60.5%). About 80% of the THA were performed via the lateral approach. The functional hip score improved from an average of 8.9 to 15.0 with 66.3% of the patients categorized as good and excellent results. There were 16 patients (17.4%) with poor outcome. The most common complications encountered were dislocation (10.1%), aseptic loosening (9.2%) and periprosthetic fracture (5.5%). Other complications were deep infection (1.8%), deep vein thrombosis (0.9%), trochanteric osteotomy complications (1.8%), superficial infection (7.3%), urinary tract infection (5.5%), pressure sore (3.7%) and respiratory complication (1.8%). Fifteen hips (13.8%) required revision. The causes for revision were aseptic loosening, dislocation and infection. Technical anomalies were recognized as one of the factors contributing to poor results. Five-year survival rate was 87.3%. Better results can be expected with increasing experience and technical skulls.

    The initial experience with the use of Hulka clips for sterilization in 100 patients is reported. In July, 1979, University Hospital physicians in Kuala Lumpur introduced spring-loaded clips, and have found the procedure to be safe and the method acceptable. The 86 patients available for the followup were admitted 1 day prior to the operation for a detailed interview, physical and pelvic examinations, pap smear, and hemoglobin estimation. The laparoscopy was performed under general anesthesia, although others report using local anesthesia, and the patients were discharged the following day. Follow-up was conducted at 3, 6, and 12 months. The women were between 25-40 years old and the majority were para 3-5; 10.5% had only 2 live births. The average age of the patients' youngest child at the time of sterilization was 2.8. Indians comprised the largest ethnic group. The problems encountered at laparoscopy generally occurred in the initial stages of the study and included: difficulty at insertion of trochar, inability to visualize fimbria, tubal transection, and the need for additional clips to ensure occlusion. 2 pregnancies were reported, 1 patient had a luteal phase pregnancy and in the other patient, the left tube was only partially occluded. The actual failure rate in the series was 1.16%, which is acceptable and similar to other reports. A distinct advantage of the clip was the low incidence of tubal transection, .6%, which is a more common occurrence with silastic bands. In addition, the clips offer good prospects for reversibility, compared to other sterilization methods.

    In September 1991, the 7th IUVDT Regional Conference on Sexually Transmitted Diseases (STDs) convened in Kuala Lumpur, Malaysia, to exchange information on the importance of controlling STDs and HIV-AIDS in Asia. Speakers from Thailand, Malaysia, and Japan provided the latest HIV-AIDS epidemiological data. In Thailand, heterosexual transmission of HIV is catching up with iv drug use. Most infected women are 15-24 years old. In Malaysia, drug use iv drug use trails heterosexual transmission of HIV. In Japan, hemophiliacs comprise 85% of HIV-positive people. Current problems do not compare to the sizable task Asian countries face in affecting the progression of the HIV-AIDS epidemic. All countries need to implement control measures quickly and at the same time. They should not pretend traditional values and beliefs would shield their people from the epidemic. Asian countries should especially stop promoting themselves as places of sexual adventure. Control programs should also target STDs. Australian presenters discussed the results of the Sydney Sexual Lifestyle Study and a study on the effect of zidovudine therapy on the prognosis of AIDS. Another presentation focused on the possibility of a vaccine for chlamydia infection. Several papers centered on the treatment of chancroid and gonococcal and nongonococcal urethritis and evaluation of a detection test for chlamydia infection. 1 participant reviewed the role of human papilloma virus in cervical carcinogenesis. Another participant demonstrated a link between bacterial vaginosis and adnexal tenderness and pelvic infection. The conference concluded with a presenter challenging everyone to meet the HIV-AIDS challenge. Reasons why current control measures do not work include inadequate facilities to manage STDs, tendency not to consider HIV another STD, failure to promote and lack of condoms, and not educating school children about HIV-AIDS.

    We have identified the beta-thalassemia mutations in 59 patients with thalassemia major and 47 patients with Hb E-beta-thalassemia, and the deletional and nondeletional alpha-thalassemia determinants in 23 out of 24 patients with Hb H disease. All persons were attending the Haematology Clinic at the National University of Malaysia in Kuala Lumpur (Malaysia). Most patients (76) were of Malay descent, while 52 patients were Chinese, and two came from elsewhere. The most frequently occurring beta-thalassemia alleles among the Malay patients were IVS-I-5 (G----C) and G----A at codon 26 (Hb E), while a few others were present at lower frequencies. The Chinese patients carried the mutation characteristic for Chinese [mainly codons 41/42 (-TTCT) and IVS-II-654 (C----T)]; Malay mutations were not observed among Chinese and Chinese mutations were virtually absent in the Malay patients. The large group of patients with Hb E-beta-thalassemia and different beta-thalassemia alleles offered the opportunity of comparing hematological data; information obtained for patients with Hb E-beta-thalassemia living in other countries was included in this comparison. Twenty-three patients with Hb H disease carried the Southeast Asian (SEA) alpha-thalassemia-1 deletion; 13 had the alpha CS alpha (Constant Spring) nondeletional alpha-thalassemia-2 determinant, while the deletional alpha-thalassemia-2 (-3.7 or -4.2 kb) was present in 10 subjects. The --/alpha CS alpha condition appeared to be the most severe with higher Hb H values. Both deletional and nondeletional types of alpha-thalassemia-2 were seen among Malay and Chinese patients.

    Growth status was examined in relation to gender and age factors in urban primary school children (6-10 years old) from low income households in Kuala Lumpur, Wilayah Persekutuan. The sample consisted of 4212 boys (53%) and 3793 girls (47%). Data on weight and height data were obtained from two sources - investigator's and teachers' measurements of the school children. This study defined mildly and significantly underweight, stunted or wasted as z-score below minus one and below minus two of the NCHS/CDC reference median, respectively. Approximately 52% (n = 4149), 50% (n = 3893) and 30% (n = 2568) of the school children were underweight, stunted and wasted, respectively. However, the majority of these undernourished children were in the mild category. Prevalence of overweight (> 2 SD of NCHS/WHO reference median) was found in 5.8% of the sample. For both, prevalence of undernutrition and overnutrition, more boys than girls were found to be underweight stunted wasted and overweight. Compared to girls, boys had lower mean z-scores for the variables height-for-age (p<0.05) and weight-for-height (p<0.01). Older children had significantly lower mean z-scores for height-for-age (p<0.001) but higher mean z-scores for weight-for-height (P<0.001) than younger children. This finding indicates that with increasing age, stunting is associated with improved weight-for-height or that the children's weights have been adapted to their short statures. In conclusion, results demonstrate a high prevalence of underweight, stunting and wasting and an increasing prevalence of overweight among these low-income school children. Efforts recommended to address health and nutrition problems among school children should include health and nutrition monitoring (e.g. growth monitoring using the existing growth data collected by schools) and interventions.

    The study presents recent data on the prevalence and pattern of nutritional anemia in the Maternity Hospital, Kuala Lumpur. A total of 309 pregnant women in their 3rd trimester, of Malay, Chinese and Indian origin from the lower socio-economic strata were randomly selected for the study. Hematological indices (including Hb, PCV, MCHC, and TRBC), serum iron, transferrin saturation and ferritin, serum folate as well as protein and albumin were determined. Based on Hb and PCV values, 30-40% of the women could be considered anemic; approximately 50% of them presented with unsatisfactory serum iron, transferrin saturation and ferritin values; 60.9% had low serum folate levels; and about 30% may be considered to be of poor protein nutriture. Anemia in the study population was seen to be related mostly to iron and to a lesser extent, folate deficiency. Hematological, iron, folate and protein status was observed to be the poorest amongst the Indian women, better in the Malay group and generally the best amongst the Chinese women. Birth records of 169 of these women revealed that all of them had live births. Nearly all the infants were delivered by normal vaginal delivery (NVD). The mean gestational age was 38.6 weeks. One of the infants had a birth weight of 2.0 kg; incidence of low birth weight, 2.5 kg, was 8.3%. Although there was a trend of deteriorating hematological, iron and protein status of women from the 0, 1-3 and 4 parity groups, these differences were not statistically significant. PMID:12267519

    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. PMID:25964827

    Introduction: 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. Methods: 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. Results: 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 < 0.05), gender (p < 0.05) and grade (p < 0.05). Males had significantly higher physically activity scores than females (p < 0.05). Intake of all micronutrients were higher than Dietary Reference Intake (DRI), except for vitamins B1, B2, C, D and E, Folate, Zinc, Magnesium, Potassium, Calcium and Phosphorus. There was a tendency for the females to overestimate their weight and 72.6% of them expressed their desire to lose weight while 60% of the males wanted to gain weight. There was also significant association between body weight status and perception of ideal body size (p = 0.000) and healthy body size (p = 0.000). Conclusion: This study provides some information for the Iranian Secondary school to design intervention programs to improve the body weight status of their students. PMID:25363094

    Colorectal adenomas are precursor lesions of colorectal cancer. Several studies have proposed that obesity is a risk factor for colorectal adenoma. This case-control study examined the relationship between body mass index (BMI), waist circumference, waistto-hip ratio (WHR), body fat percentage and colorectal adenomatous polyps (CRA) in patients who have had a colonoscopy at the Hospital Kuala Lumpur (HKL). Fifty-nine patients (42 males and 17 females) positively identified as having CRA and 59 polypfree subjects were recruited as controls (33 males and 26 females). A pre-tested questionnaire was used to collect socio-economic information, while anthropometric measurements were determined directly by established methods. The mean BMI of female case subjects was significantly higher than control females (25.63 + 4.87 kg/m2 vs. 23.86 + 3.70 kg/m2, p<0.05) but the difference in BMI was not significant in men. The mean WHR of male subjects was significantly higher in the case group (0.92 + 0.07 vs. 0.90 + 0.06, p<0.05). After adjusting for confounders, waist circumference was the only indicator that was found to significantly increase the risk for CRA in women (OR = 6.349, 95% CI = 1.063 - 37.919). Higher BMI, WHR and body fat percentage showed a non-significant risk in female subjects. In men, none of the obesity indicators were found to be significant risk factors for CRA. These findings suggest that abdominal obesity may be a contributing factor to CRA risk particularly in women. A prospective study is needed to confirm the role of obesity in the development of CRA in Malaysians. PMID:22691799

    Background: There is a paucity of data on quality of life issues in patients with leprosy suffering from erythema nodosum leprosum (ENL). Thus, we aim to study the effect of ENL on quality of life. Materials and Methods: This cross-sectional study was conducted in Hansen's Clinic, Hospital Kuala Lumpur between January 2010 and December 2013 among patients with multibacillary leprosy using the Dermatology Life Quality Index (DLQI). Results: A total of 153 patients participated with 31.4% suffering from ENL. The mean age at presentation was 40.5 ± 16.49 years. The mean DLQI was 7.1 ± 3.72. Patients with ENL were younger (mean age 36.5 vs. 42.4, P = 0.026), had higher mean bacteriologic index (4.3 vs. 3.8, P = 0.004), had physical deformities (47.9% vs. 31.4%, P = 0.049), and had higher mean DLQI score (9.1 vs. 6.2, P < 0.001). All the DLQI domains were higher in patients suffering from ENL except the treatment domain. Symptoms and feeling was the domain with the largest effect followed by daily activities and leisure. Personal relationship had the lowest effect. Conclusion: Quality of life impairment in patients with leprosy in Malaysia is moderate, with larger effect among patients with ENL. The impairment in ENL is comparable to itchy skin conditions such as urticarial and is worse than chronic skin disease such as psoriasis. Thus, it is essential that management of leprosy incorporate quality of life issues. PMID:27559497

    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.

    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.

    A nutritional status study was carried out among a group of young Chinese adults, aged between 19 and 25, in Kuala Lumpur, Malaysia. Subjects comprised 108 young adults (55 women, 53 men) who were students at two institutes of higher learning. Physical characteristics were evaluated by anthropometric measurements while food intake was determined with a 3-day food record. Blood cholesterol and triglyceride were assessed using the Reflotron analyser. Birthweight was obtained from birth certificates or by proxy. The results showed that the mean body mass index (BMI) for men and women was 21.4 ± 3.3 and 20.0 ± 2.0, respectively, indicating normal weight. Further analysis of BMI classification demonstrated that 28% of men and 39% of women were underweight, 11% of men and 2% of women were overweight while 2% of men were obese. Mean waist-to-hip ratio showed that the subjects had a low risk of developing cardiovascular disease (0.72 ± 0.03 women; 0.81 ± 0.05 men). Mean energy intake was 8841 ± 1756 kJ per day for men and 6426 ± 1567 kJ per day for women. Closer analysis of energy intake of the subjects showed that 86% of men and 91% of women were consuming below the Malaysian recommendation for energy. Nutrients found to be deficient in at least one third of women were calcium, vitamin A, niacin and iron. Mean cholesterol intake in the diet was 278.7 ± 108.7 mg in men and 207.0 ± 82.5 mg in women and there was a significant difference between genders. Blood cholesterol and triglyceride levels were 3.88 ± 0.76 mmol/L and 1.08 ± 0.33 mmol/L, respectively in men, while these levels were lower in women, 3.87 ± 0.80 mmol/L for cholesterol and 0.99 ± 0.29 mmol/L for triglyceride. A general trend of higher mean blood cholesterol and triglyceride levels was shown in adults who were born with lower birthweights.

    BACKGROUND/OBJECTIVES This study aims to determine contribution of meal frequency, self-efficacy for healthy eating, and availability of healthy foods towards diet quality of adolescents in Kuala Lumpur, Malaysia. SUBJECTS/METHODS This study was conducted among 373 adolescents aged from 13 to 16 years old. Diet quality of the respondents was assessed using the Healthy Eating Index for Malaysians. Meal frequency, self-efficacy for healthy eating, and availability of healthy foods were assessed through the Eating Behaviours Questionnaire (EBQ), self-efficacy for healthy eating scale, and availability of healthy foods scale, respectively. RESULTS The majority of the respondents (80.7%) were at risk of poor diet quality. Males (mean = 34.2 ± 8.2%) had poorer diet quality than females (mean = 39.9 ± 9.0%) (t = -5.941, P < 0.05). Malay respondents (mean = 36.9 ± 8.7%) had poorer diet quality than Indian respondents (mean = 41.3 ± 10.0%) (F = 2.762, P < 0.05). Age (r = 0.123, P < 0.05), self-efficacy for healthy eating (r = 0.129, P < 0.05), and availability of healthy foods (r = 0.159, P < 0.05) were positively correlated with the diet quality of the respondents. However, meal frequency was not correlated with the diet quality of the respondents. Multiple linear regression analysis showed that being a male, being a Malay, low self-efficacy for healthy eating, and low availability of healthy foods contributed significantly towards poor diet quality among respondents. CONCLUSIONS In short, sex, ethnicity, self-efficacy for healthy eating, and availability of healthy foods were associated with diet quality among adolescents. Health practitioners should take into consideration of differences in sex and ethnicity during implementation of nutrition-related intervention programs. Self-efficacy for healthy eating and availability of healthy foods should be included as important components in improving diet quality of adolescents. PMID:26425281

    The main aim of this study is to determine the causes and the epidemiological aspects of sudden natural deaths. Data were collected from 545 sudden natural autopsies in UMMC, Kuala Lumpur over a five-year period, from 1st January 2000 to 31st December 2004. There were 475 males and 70 females. The largest number of sudden natural deaths was in the age group of 41-50 years. 35.8%, 30.5% and 11.7% of the patients were Chinese, Indian and Malay, respectively. A majority of the patients were married (59.8%) and came from the semiskilled-unskilled group (30.6%). The monthly distribution was almost constant. Cardiovascular diseases were the most important cause contributing 64.9% in sudden natural deaths. PMID:16914354

    Eighty consecutive patients who came to collect their prescriptions for pressurised aerosol inhalers at the Pharmacy of the University Hospital, Kuala Lumpur, were interviewed regarding their use of the pressurised inhaler. Their inhaler technique was also assessed. A significant proportion inhaled the steroid aerosol before the bronchodilator and 23.5% used the steroid inhaler for relief of acute dyspnoea. Only 28.8% of the 80 patients performed correctly all 6 steps necessary for the proper use of inhalers. The most common mistake was the failure to inhale slowly and deeply. Patients who had used the device for more than 5 years performed better, while correct inhaler technique was not dependent on the patient's sex, age or level of education.

    The gastrointestinal helminth infection status of 1574 children living in a slum area of Kuala Lumpur, Malaysia was assessed by quantitative coprology. Almost two-thirds were infected with Trichuris trichiura, 49.6% with Ascaris lumbricoides, and 5.3% with hookworm. Infection prevalence rose rapidly to a stable asymptote at 7 years of age, and the age-intensity profile was convex with maximal values in the 5-10 year age classes. This pattern was the same for males and females, but differed markedly between different ethnic groups. The frequency distributions of A. lumbricoides and T. trichiura were highly overdispersed (k values were 0.21 and 0.27, respectively), and age-dependent over the 0-8 year age classes. This suggests that the force of infection with these nematodes is lower in infants than in older children.

    The incidence of infections due to beta-lactamase-producing Neisseria gonorrhoeae is increasing in many parts of the world. An epidemiologic survey of infections caused by beta-lactamase-producing strains of N. gonorrhoeae at the University Hospital, Kuala Lumpur, from February 1977 to December 1985 (106 months) showed that the incidence rose from 4.8% (two cases) in 1977 to 49.4% (39 cases) by the end of 1985. The highest incidence of gonococcal infections was found to be in the group aged 20-39 years; the male-to-female ratio was 1.55:1. The mean inhibitory concentrations of benzylpenicillin were 0.12 microgram/ml for non-beta-lactamase-producing strains and 16 micrograms/ml for isolates of N. gonorrhoeae that produce beta-lactamase.

    Methicillin-resistant Staphylococcus aureus (MRSA) as a hospital pathogen has presented many clinical problems in the University Hospital, Kuala Lumpur, Malaysia since 1978. The need for control of spread of these organisms became evident by 1985 when it was noted that the incidence of MRSA among S. aureus isolated from hospital inpatients had increased from 11.5% in 1979 to 18.8% in 1985. The characteristics of 50 MRSA isolates associated with nosocomial infections in the hospital are described here. The predominant strains produced Type IV coagulase and 84% of isolates studied showed moderate to high resistance to methicillin with MIC values of 25 mg l-1 or higher. All the MRSA isolates that could be phagetyped were susceptible to Group III phages, with 76.6% of the isolates being susceptible to phage 85. At least 10 different patterns were distinguishable by plasmid typing, the majority of isolates harbouring up to four small plasmids.

    Rodents were collected from five wet markets (Chow Kit, Dato Keramat, Setapak, Jinjang and Kepong) in Kuala Lumpur, Federal Territory between March to April 2006. Ninety seven rats were trapped using wire traps measuring 29 x 22 x 50 cm baited with fruits, coconuts, dried fish or sweet potatoes. A total of 17 different species of parasites were identified from three species of rats out of which 11 (65%) were identified to be zoonotic. The helminths identified from the urban rats were nematodes- Capillaria hepatica, Gongylonema neoplasticum, Heterakis spumosa, Heterakis sp., Masterphorus muris, Nippostrongylus brasiliensis, Physolaptera sp., Pterogodermatis sp., Rictularia tani and Syphacia muris; cestodes- Hymenolepis nana, Hymenolepis diminuta, Hymenolepis sabnema, Hymenolepis sp., Raillietina sp. and Taenia taeniaeformis, and acanthocephalan- Moniliformis moniliformis. The following parasites are of potential medical importance: C. hepatica, G. neoplasticum, R. tani, S. muris, H. diminuta, H. nana, Raillietina sp. and T. taeniaeformis.

    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 Ex-Gratia Compensation Scheme was introduced by the Government of Malaysia in 1994 to provide compensation, which is not covered by any prior legislation, for all its workers suffering from injuries and illnesses due to work. Despite more than ten years of implementation, the submission for claims is still minimal and there is an impression that awareness on the provision of Ex-Gratia benefit among government employees, especially health care staff, is poor. A cross sectional survey was conducted at a medical department of a government hospital in Kuala Lumpur to assess the knowledge and awareness level on Ex-Gratia among a representative group of front line health care workers. The results show that the respondents' knowledge on Ex-Gratia is generally poor as compared to knowledge on the Social Security (SOCSO) Schemes. Majority of the respondents are unsure whether they will be compensated in case of occupational illness and injuries. They also do not know what kind of compensation scheme they are currently eligible. There is an urgent need for the Treasury and health care managers to expand the knowledge and awareness on Ex-Gratia among health care workers. PMID:19385489

    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. PMID:27325078

    The concentrations of polycyclic aromatic hydrocarbons (PAHs) in atmospheric particles and roadside soil particles were measured at eight locations in the city center and the suburb of Kuala Lumpur, Malaysia. Atmospheric particles were collected using high-volume PM-10 sampler on glass fiber filters over 24 h average sampling period. Both types of samples were extracted with dichloromethane by ultrasonic agitation. The extracts were then fractionated on an alumina-silica column and the aromatic fraction was subjected to gas chromatography-mass spectrometric (GC-MS) analysis. Total PAH concentrations in the atmospheric particles and roadside soil particles were found to be 6.28±4.35 ng m -3 and 0.22±0.11 μg g -1, respectively. Benzo[ g, h, i]perylene and coronene were found to be the most abundant PAHs in airborne particles at all locations. The most abundant PAHs in the roadside soil particles were fluoranthene, pyrene and phenanthrene.

    A total of 676 palpable breast lumps seen in the Breast Clinic, University Hospital, Kuala Lumpur from August 1993 to August 1994 were subjected to fine needle aspiration cytology. Fifty-four were reported as inadequate, 501 benign, 95 malignant and 26 suspicious. One hundred and eighty-seven aspirates had histological correlation, while 34 of the malignant aspirates had clinical correlation. The majority of the other 455 patients were followed up for a period of 60 to 72 months without any malignancies becoming apparent. For analysis, only the 221 cases with histological or clinical correlation were included, (the suspicious category was included into the positive group and the inadequate cases were excluded), giving a sensitivity of 91.7%, a specificity of 91.7% and a diagnostic accuracy of 91.7%. Breast cytology was an accurate and rapid method of diagnosis of breast diseases, and in a busy surgical unit with limited operating time, it allowed for the triage of patients with breast complaints in deciding which cases needed early open biopsy. A negative cytology does not exclude the possibility of cancer, as there was a false negative rate of 11%. However by utilising a diagnostic triad of clinical examination, radiological assessment and fine needle aspiration cytology, the risk of missing a malignancy is small.

    Homicides as a result of slash/chop injuries are not commonly reported in forensic literature. A 10 year retrospective study from 1987 to 1996 was performed on the pattern of homicidal slash/chop injuries in University Hospital, Kuala Lumpur. A total of 37 cases were analysed. The ages ranged from 17 to 85 years. The victims consisted of Indonesian (37.8%), Chinese (27.0%), Indian (24.3%) and Malay (8.1%) ethnic groups; 2.7% of the cases were not identified. Most of the cases were due to intentional violence (n = 27), while the rest consisted of domestic violence (n = 2), robbery (n = 2), psychiatric homicide (n = 1), accident (n = 2) and unclassified (n = 3). In the intentional violence group, the majority of the victims (n = 16) had more than five wounds. In contrast, the victims in other categories had less than five wounds each, with the exception of a single case in the psychiatric-homicide group. In homicide victims with a single wound, the most common site of injury was the neck. In those with multiple wounds, the common sites were the head and neck. Sixteen cases showed defence injuries, all of them belonging to the intentional-violence group. The reasons for the high incidence of homicidal slash/chop wounds are discussed, as well as the difficulties associated with interpretation of such wounds.

    The objective of this study was to ascertain the extent changes have occurred in the epidemiology of human rotavirus electropherotypes from the same location 7 to 8 years after an earlier study. Genomic RNA profiles of rotaviruses from diarrhoeic children admitted to the Kuala Lumpur Hospital from April to December 1996 were determined by polyacrylamide gel electrophoresis and silver staining. A total of 179 group A rotaviruses were detected from 870 children: 175 with legible staining of all RNA segments were classified into 14 distinct electropherotypes (10 and 4 with long and short migration patterns respectively). In addition, the results revealed: high predominance of long pattern electropherotypes (94% of the total electropherotypes); most long electropherotypes with RNA profiles which all 11 RNAs migrated separately (8 of 10 electropherotypes); all short electropherotypes had segments 2 and 3 that co-migrated; presence of a very numerically dominant electropherotype (75% of all electropherotypes); frequent co-circulation of the dominant electropherotype-present throughout the study period--with other electropherotypes present for limited periods; sequential temporal appearances by similar electropherotypes. These observations were similar to that of an earlier study conducted in 1988/89. Nevertheless, the dominant electropherotype in the present study was different and not among the electropherotypes detected in the earlier study.

    From October 1996 to March 1997, 31 children with febrile convulsions were admitted to the University Hospital, Kuala Lumpur. Human Herpesvirus 6 (HHV 6) was virologically and/or serologically confirmed to be the cause of the febrile episode in 5 of these children (16.1%). Age, sex and other associated clinical features (diarrhoea, cough, running nose and type of seizure) were not useful in differentiating cases of febrile convulsion due to HHV 6 from those of other aetiology. However, uvulo-palatoglossal junctional ulcers were noted in children in whom the cause of the seizure could be attributed to HHV 6 but not in the remaining cases in the study group. HHV 6 DNA was detected in peripheral blood mononuclear cells from all patients with febrile convulsions attributed to HHV6, and in patients shown serologically to have already been exposed to the virus by nested polymerase chain reaction amplification. Only genotype HHV 6B was detected from patients with seizure due to HHV 6 but both genotype 6A and 6B were detected in the remaining cases studied.

    This study investigated the impact of clinical audit training on record-keeping behavior of dental students and students' perceptions of the clinical audit training. The training was delivered to Year 4 and Year 5 undergraduates at the School of Dentistry, International Medical University, Kuala Lumpur, Malaysia. It included a practical audit exercise on patient records. The results were presented by the undergraduates, and guidelines were framed from the recommendations proposed. Following this, an audit of Year 4 and Year 5 students' patient records before and after the audit training was carried out. A total of 100 records were audited against a predetermined set of criteria by two examiners. An email survey of the students was also conducted to explore their views of the audit training. Results showed statistically significant improvements in record-keeping following audit training. Responses to the email survey were analyzed qualitatively. Respondents reported that the audit training helped them to identify deficiencies in their record-keeping practice, increased their knowledge in record-keeping, and improved their record-keeping skills. Improvements in clinical audit teaching were also proposed.

    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.

    Background 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. Methods 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. Results 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 (P<0.05) but not in males (P>0.05). Ethnic differences in bone health indices and prevalence of osteoporosis/osteopenia were not observed (P>0.05). Conclusion 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. PMID:27358558

    This study assesses waste management and recycling practices of the urban poor households residing as squatters and in low-cost flats of Kuala Lumpur city, Malaysia. To attain the objective, the study employed some statistical techniques such as t-tests of equality of means, one-way analysis of variance, chi-squared 'likelihood ratio' tests, and simple descriptive statistics. The statistical techniques were used to determine and analyse the factors that significantly influence the environmental behaviour of the urban poor concerning solid waste management, particularly their recycling practices. The findings of the study show that the urban poor and low-income communities have been proved to behave in ways that are consistent with and conducive to environmentally friendly solid waste management. This study provides evidence that the urban poor and low-income communities are the main recyclers, re-users, and source-reducers of their household solid waste. The study, however, suggests that policies should be formulated to focus on promoting knowledge, education, and the skills of the urban poor and, in addition, to empower them as a means of improving their quality of life.

    This study was carried out to determine the concentration of lead (Pb), anions, and cations at six primary schools located around Kuala Lumpur. Low volume sampler (MiniVol PM10) was used to collect the suspended particulates in indoor and outdoor air. 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 Ca(2+) (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 Mg(2+), Ca(2+), NO3 (-), SO4 (2-), and Pb(2+), were higher in outdoor air than in indoor air at all sampling stations.

    A study was conducted to determine the feasibility of establishing a sentinel human immunodeficiency virus (HIV) surveillance system involving patients with sexually transmitted diseases attending private clinics and a government sexually transmitted disease clinic in Kuala Lumpur, Malaysia. Information on risk behaviours for HIV infection were also collected. A total of 84 female and 91 male patients were interviewed and tested for HIV infection; 41.7% of the women reported working as prostitutes, other occupations included masseuses, hairdressers, waitresses, salesgirls, receptionists, factory workers, and others. The most common diagnosis was gonorrhoea. Other diagnoses included non-specific genital infection, pelvic inflammatory disease, genital herpes and syphilis. 58.3% of the women had a hundred or more sex partners during the previous month; 99% had 6 or more sex partners. Only 4.8% of female patients had their male partners using condoms most of the time, 11.9% hardly used condoms at all. Of the males, 93.3% were heterosexual, while 6.7% were bisexuals, 41.1% had between 6-20 different partners in the previous year. 78.0% of them had prostitutes as their sex partners most of the time. 41.8% had experiences in Thailand and the Philippines. 73.6% never used condoms, while 19.8% only used condoms rarely. Although all patients were tested negative for HIV antibodies, lot quality assurance sampling methods indicate that the upper limits of prevalences for females and males were 3.5% and 3.3% respectively, at a 5% type I error. The study has shown that it is feasible to carry out a sentinel surveillance programme among STD patients and provided useful baseline data for future comparisons.(ABSTRACT TRUNCATED AT 250 WORDS)

    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. PMID:22691857

    Consumption of repeatedly heated oil can be detrimental to health. The objective of this study was to determine the level of knowledge, attitude and practice of night market food outlet operators in Kuala Lumpur regarding the usage of repeatedly heated cooking oil. The quality of cooking oil was also investigated. A cross-sectional study involving pretested questionnaire was undertaken in April 2009. The questionnaire was designed as a tool to collect data from the respondents (n=100) by face-to-face interview. The results showed that majority of respondents had only moderate (53.0%) or low (18.0%) level of knowledge regarding this issue. Most respondents (67.0%) agreed that it is not a good practice. The majority (69.0%) agreed that the usage of repeatedly heated cooking oil is detrimental to health. Despite that, most respondents (63.0%) admitted that they had used cooking oil repeatedly. Most (62.0%) of the cooking oil samples taken from the night market food outlets were considered fit for human consumption. In conclusion, the level of knowledge of night market food outlet operators in Kuala Lumpur regarding this issue needs to be improved in order to ensure the safety of fried food purchased from such establishments.

    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.

    A retrospective review of patients with congenital dislocation of the hip (CDH) seen in the Institute of Orthopaedics, Kuala Lumpur General Hospital from 1975 to 1988 is presented. There was a female predominance of 17 to five. The average follow-up was 43 months and the average age at final assessment was 63 months. The results were assessed clinically and radiographically using Severin criteria. Eighty eight percent of the hips had excellent or good clinical results at final review compared with 40% of the hips which had excellent or good radiological grading (Severin I and II). Initial acetabular angle before treatment and types of treatment appeared to have a correlation with the final result. The incidence of avascular necrosis was 16%.

    This small, cross-sectional study assessed the reliability of 3 scales from the Job Content Questionnaire (JCQ)-decision latitude, psychological job demand, and social support-in a group of office workers in a multinational company in Kuala Lumpur. A universal sample of 30 white-collar workers from a department of the company self-administered the English version of the JCQ comprising 21 core items selected from the full recommended version of 49 items on-site. Reliability (internal consistency) was evaluated using Cronbach's alpha coefficients for each scale. Corrected item-total correlation was presented for each and every item. Cronbach's alpha coefficients were acceptable for decision latitude (.76) and social support (.79) but slightly lower for psychological job demand (.64). Values for all item-total correlations for all 3 scales were greater than .3. In conclusion, this study suggests that the JCQ is a reliable scale for assessing job stress in this group of workers.

    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.

    Introduction: 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. Subjects and Methods: 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. Results: 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). Conclusions: 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. PMID:26889274

    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, p<0.05), WC (r=0.852, p<0.05) and body fat percentage. Body fat percentage also show high correlation with weight (r=0.759, p<0.05) and WC (r=0.768, p<0.05. The result from 173 of 378 subjects that were selected for random blood test found that 4.6%, 3.5% and 26.0% had diabetes, high cholesterol and high triglyceride respectively. There was a weak correlation between random blood glucose level with weight (r=0.221, p<0.05), BMI (r=0.243, p<0.05), WC (r=0.298, p<0.05), body fat percentage (r=0.163, p<0.05) and age (r=0.223, p<0.05).

    Effective antiretroviral drugs have been developed that, if continuously administered (although with simplification strategies once a patient's viral titer is suppressed) allow for a functional cure resulting in an almost normal life despite the presence of viral reservoirs. In that sense, observations that combination antiretroviral therapy has an untoward suppressive effect on antibody-dependent cellular cytotoxicity against T cells permitting the establishment of such viral reservoirs were discussed for its implications in the use of vaccines and/or modulators of the immune function to clear latent infections and the risk for reactivation (Madhavi, V. et al., Abst MOLBPE05). In addition to latent viral reservoirs, individual patient characteristics may also influence response to antiretroviral therapy, as exemplified by the increased likelihood of highly active antiretroviral therapy in patients carrying certain polymorphic variants (rs2229109, rs6961419) of the P-glycoprotein 1 gene (Dias, J. et al., Abst MOPE034). These, and many other important news derived from research into novel approaches to fight HIV infection were discussed during the International AIDS Society (IAS) meeting in Kuala Lumpur, as summarized in the following report.

    A variety of betel/areca nut/tobacco habits have been reviewed and categorized because of their possible causal association with oral cancer and various oral precancerous lesions and conditions, and on account of their widespread occurrence in different parts of the world. At a recent workshop in Kuala Lumpur it was recommended that "quid" be defined as "a substance, or mixture of substances, placed in the mouth or chewed and remaining in contact with the mucosa, usually containing one or both of the two basic ingredients, tobacco and/or areca nut, in raw or any manufactured or processed form." Clear delineations on contents of the quid (areca nut quid, tobacco quid, and tobacco and areca nut quid) are recommended as absolute criteria with finer subdivisions to be added if necessary. The betel quid refers to any quid wrapped in betel leaf and is therefore a specific variety of quid. The workshop proposed that quid-related lesions should be categorized conceptually into two categories: first, those that are diffusely outlined and second, those localized at the site where a quid is regularly placed. Additional or expanded criteria and guidelines were proposed to define, describe or identify lesions such as chewer's mucosa, areca nut chewer's lesion, oral submucous fibrosis and other quid-related lesions. A new clinical entity, betel-quid lichenoid lesion, was also proposed to describe an oral lichen planus-like lesion associated with the betel quid habit.

    This work describes the application of the electrical resistivity (ER) method to delineating subsurface structures and cavities in Kuala Lumpur Limestone within the Batu Cave area of Selangor Darul Ehsan, Malaysia. In all, 17 ER profiles were measured by using a Wenner electrode configuration with 2 m spacing. The field survey was accompanied by laboratory work, which involves taking resistivity measurements of rock, soil, and water samples taken from the field to obtain the formation factor. The relationship between resistivity and the formation factor and porosity for all the samples was established. The porosity values were plotted and contoured. A 2-dimensional and 3-dimensional representation of the subsurface topography of the area was prepared through use of commercial computer software. The results show the presence of cavities and sinkholes in some parts of the study area. This work could help engineers and environmental managers by providing the information necessary to produce a sustainable management plan in order to prevent catastrophic collapses of structures and other related geohazard problems.

    Lumpur Sidoarjo is one of geothermal fluid types which has a great potential as source of lithium. Adsorption method with Lithium Manganese Oxide (LiMn2O4) as an adsorbent has been chosen for lithium recovery process due to low production cost and environmental friendly. LiMn2O4 was synthesized by hydrothermal method at 200 °C for 24 hrs, 48 hrs, and 72 hrs. As prepared LiMn2O4 powder is treated by acid treatment with 0.5 M HCl solution for 24 hrs. XRD test result reveals that all of as-prepared samples are indexed as spinel structure of LiMn2O4 (JCPDS card no 35-0782) with no impurity peaks detected. SEM images show that LiMn2O4 has nanoparticles morphology with particle size around 25 nm. The highest adsorption efficiency of adsorbent is obtained by sample hydrothermal for 72 hrs with 42.76%.

    The main objective of this paper is to examine the psychometric properties of the Malay Version of the Hospital Anxiety and Depression Scale (HADS), tested on 67 husbands of the women who were diagnosed with breast cancer. The eligible husbands were retrieved from the Clinical Oncology Clinic at three hospitals in Kuala Lumpur, Malaysia. Data was collected at three weeks and ten weeks following surgery for breast cancer of their wives. The psychometric properties of the HADS were reported based on Cronbach' alpha, Intraclass Correlation Coefficients (ICC), Effect Size Index (ESI), sensitivity and discriminity of the scale. Internal consistency of the scale is excellent, with Cronbach's alpha of 0.88 for Anxiety subscale and 0.79 for Depression subscale. Test-retest Intraclass Correlation Coefficient (ICC) is 0.35 and 0.42 for Anxiety and Depression Subscale, respectively. Small mean differences were observed at test-retest measurement with ESI of 0.21 for Anxiety and 0.19 for Depression. Non-significant result was revealed for the discriminant validity (mastectomy vs lumpectomy). The Malay Version of the HADS is appropriate to measure the anxiety and depression among the husbands of the women with breast cancer in Malaysia. PMID:21790225

    Indo-Asians in the UK are at an increased risk of coronary artery disease (CAD); this may be a reflection of their cardiovascular risk factor profile as well as of a more sedentary lifestyle. We hypothesised that Indo-Asians in Malaysia and the UK may exhibit a similar cardiovascular risk factor and physical activity profile, which would be more adverse compared with caucasians. We studied 70 consecutive Indo-Asian patients admitted to hospitals in Kuala Lumpur, Malaysia (n=42; 35 males; mean age 60.6 years, SD 11.8); and Birmingham, England (n=28; 20 males; mean age 60.8 years, SD 12.9). Both groups of Indo-Asian patients were compared with 20 caucasian patients (13 males; mean age 62.7 years, SD 9.4) admitted with myocardial infarction from Birmingham. There was a higher prevalence of diabetes among Indo-Asians in both countries than among caucasians (p=0.0225). By contrast, caucasians had a higher prevalence of hypercholesterolaemia (p=0.0113), peripheral vascular disease (p=0.0008), regular alcohol consumption (p<0.0001) and family history of CAD (p=0.0041). There were no significant differences in mean age, body mass index or blood pressures. There was a significantly lower leisure activity score (p=0.001) and total physical activity score (p=0.003) among Indo-Asians in both countries than among caucasians. This survey has demonstrated differences in cardiovascular risk factors among Indo-Asian and caucasian patients. The high prevalence of diabetes, as well as the lower physical activity and sedentary lifestyles among Indo-Asians, in both Malaysia and the UK, may in part contribute to the high incidence of CAD in this ethnic group.

    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 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.

    Formerly thought to have a constant incidence rate throughout the world, Wilms' tumour (nephroblastoma) has been shown to be less common among Asian children. A retrospective demographic and morphological study of Wilms' tumour histologically diagnosed over a 22-year period at the Department of Pathology, University Hospital, Kuala Lumpur was conducted to assess for inherent demographic and morphological differences between tumours in Malaysian children and those of Western populations. Thirty-seven cases of histologically proven Wilms' tumour qualified for inclusion in this study. 19 patients were Chinese, 13 Malay, 4 Indian and 1 Anglo-asian. 21 were male and 16 were female (M:F ratio = 1.3:1). Their ages ranged from 1 month to 4 years. 70.3% of the patients were below 2 years of age. 36 cases had unilateral and 1 bilateral tumours. Of unilateral tumours, 19 involved the left kidney and 17 the right. Histological assessment, based on criteria of the National Wilms' Tumor Study Group, revealed 20 (52.6%) tumours with a mixed pattern while 8 (21.1%) showed epithelial, 7 (18.4%) blastemal and 3 (7.8%) stromal-predominant patterns. Anaplasia was observed in only 2 tumours (5.3%). There was no obvious difference in age range and sex distribution, laterality of tumours and incidence of anaplasia between this and Western studies. No ethnic predilection was observed. A notably larger percentage of cases were below 2 years of age. Also, a larger proportion of epithelial-predominant and a lower proportion of blastemal-predominant tumours was observed compared with patterns reported from Western populations.

    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), 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. Conclusion 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. PMID:25438066

    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; p<0.01) and lower educational level of mothers (OR=0.749; p<0.01) and fathers (OR=0.802; p<0.05) were found to be significant risk factors for food insecurity. The study, however, did not find any significant difference in children's nutritional status according to household 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 < 0.001), more likely to be female (36 vs 21 %, p = 0.004), and to have been on HAART for less time (61 [IQR 35, 108] vs 153 weeks [IQR 63, 298]; p < 0.001). Among all clients, similar proportions of refugee and host clients were <95 % adherent to pharmacy refills (26 vs 34 %, p = 0.15). When restricting to clients on treatment for ≥25 weeks, similar proportions from each group were not virologically suppressed (19 % of 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.

    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 < 0.001), more likely to be female (36 vs 21 %, p = 0.004), and to have been on HAART for less time (61 [IQR 35, 108] vs 153 weeks [IQR 63, 298]; p < 0.001). Among all clients, similar proportions of refugee and host clients were <95 % adherent to pharmacy refills (26 vs 34 %, p = 0.15). When restricting to clients on treatment for ≥25 weeks, similar proportions from each group were not virologically suppressed (19 % of 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.

    We describe the HIV risk perception, sexual behavior, and HIV prevalence among 423 men-who-have-sex-with-men (MSM) clients who received voluntary counseling and testing (VCT) services at a community-based center in Kuala Lumpur, Malaysia. The mean age was 29 years old. One hundred one (23.9%) clients rated themselves as low risk, 118 (27.9%) as medium risk, 36 (8.5%) as high risk, and 168 (39.7%) were unsure of their risk. Twenty-four (9.4%) clients tested HIV positive (4 (4%) low risk, 9 (7.6%) medium risk, 11 (30.6%) high risk, and 13 (7.7%) unsure risk). We found a positive correlation between risk perception and HIV infection in this study. Clients with high HIV risk perception have 17x the odds of testing HIV positive compared to low risk clients. High HIV risk perception was significantly associated with multiple sex partners, multiple types of sex partners, alcohol use before intercourse, unprotected sex beyond 6 months, and inconsistent condom use during anal sex compared to low risk clients. There were no statistically significant differences between medium risk and unsure risk clients compared to low risk clients. Strategies should be targeted towards change in sexual practices among those who are perceived to be at high risk.

    Expansion of antiretroviral treatment programs have led to the growing concern for the development of antiretroviral drug resistance. The aims were to assess the prevalence of drug resistant HIV-1 variants and to identify circulating subtypes among HAART-naïve patients. Plasma specimens from N = 100 HIV+ HAART-naïve adult were collected between March 2008 and August 2010 and viral RNA were extracted for nested PCR and sequenced. PR-RT sequences were protein aligned and checked for transmitted drug resistance mutations. Phylogenetic reconstruction and recombination analysis were performed to determine the genotypes. Based on the WHO consensus guidelines, none of the recruited patients had any transmitted drug resistance mutations. When analyzed against the Stanford guidelines, 35% of patients had at least one reported mutation that may reduce drug susceptibility to PI (24%), NRTI (5%), and NNRTI (14%). The commonly detected mutation that may affect current first line therapy was V179D (3%), which may lead to reduced susceptibility to NNRTI. The predominant circulating HIV-1 genotypes were CRF01_AE (51%) and CRF33_01B (17%). The prevalence of unique recombinant forms (URF) was 7%; five distinct recombinant structures involving CRF01_AE and subtype B' were observed, among them a cluster of three isolates that could form a novel circulating recombinant form (CRF) candidate. Transmitted drug resistance prevalence among HAART-naïve patients was low in this cohort of patients in Kuala Lumpur despite introduction of HAART 5 years ago. Owing to the high genetic diversity, continued molecular surveillance can identify the persistent emergence of HIV-1 URF and novel CRF with significant epidemiological impact.

    Background: Traumatic brain injury (TBI) has been associated with an acute stress response mediated by the sympathoadrenomedullary axis, which can be assessed by measuring blood glucose level. Methods: This prospective observational study was conducted for a year in 2007 among 294 patients who had been treated for TBI in Hospital Kuala Lumpur. Patients fulfilling the set criteria were recruited into the study and data, including blood glucose level and Glasgow Outcome Score at 3-month follow-up, were collected. Results: 294 patients were included in the study: 50 females (17.0%) and 244 males (83.0%). The majority of cases were young adult patients (mean age of 34.2 years, SD 13.0). The mean blood glucose level during admission and post-surgery were 6.26 mmol/L (SD 1.30, n = 294) and 6.66 mmol/L (SD 1.44, n = 261), respectively. Specifically, the mean admission glucose level associated with mild TBI was 5.04 mmol/L (SD 0.71); moderate TBI, 5.78 mmol/L (SD 1.02); and severe TBI, 7.04 mmol/L (SD 1.18). The mean admission glucose level associated with a poor outcome in patients with isolated TBI was 6.98 mmol/L (SD 1.21). Patients with admission glucose of 5.56 mmol/L (SD 1.21) were more likely to have a favourable outcome. Conclusion: Mild, moderate, and severe TBI were associated with an increase in blood glucose levels during admission, and the mean increase in glucose levels is based on the severity of the isolated TBI. Surgical intervention did not cause further significant changes in blood glucose levels. Patients with isolated TBI and minimal increases in blood glucose levels were more likely to have a favourable outcome. PMID:22589675

    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.

    Bilateral vocal fold immobility (BVFI) is commonly caused by injury to the recurrent laryngeal nerve (RLN) and leads to stridor and dyspnea of varying onsets. A retrospective study was done at the Department of Otorhinolaryngology of Universiti Kebangsaan Malaysia Medical Centre on laser microsurgical posterior cordectomy for BVFI. The objectives were to identify the average duration of onset of stridor from the time of insult and to evaluate the outcome of laser posterior cordectomy as a surgical option. From 1997 to 2007, a total of 31 patients with BVFI were referred for surgery. Twelve patients had tracheostomy done prior to the procedure, whereas 19 patients were without tracheostomy. Ten patients were successfully decannulated, and only 4 patients had complications related to the procedure. The minimum onset of stridor was 7 months, maximum onset of stridor was 28 years, and the mean onset of stridor was 8.7 years. The commonest complication observed was posterior glottic adhesion following bilateral posterior cordectomy. Laser endolaryngeal posterior cordectomy is an excellent surgical option as it enables successful decannulation or avoidance of tracheostomy in patients with BVFI. The onset of stridor took years after the insult to the recurrent laryngeal nerves. PMID:27660547

Majority of the patient (70%) presented within a week of symptom and significant number of them came with fever and swelling of the affected limb. Sedimentation rate was found to be raised in all of them. Fifty-four (55%) of them were treated surgically. The average antibiotic time was one week by intravenous administration followed by additional oral therapy for period up to four weeks. Average follow-up was 9 months. Six of them (7.5%) end up with various complication which was believed to be due to delay in getting medical treatment.

    A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermatitis. Allergic hand dermatitis was the commonest presentation in occupational allergic dermatitis. This was followed by dermatitis of the exposed skin (face, neck, hands and forearms). The common sensitising agents identified were rubber chemicals and nickel. The two main groups at risk were factory workers and medical personnel. The common allergens found in factory workers were epoxy resin, pewter, nickel and rubber chemicals. Exposure dermatitis occurred in patients working in the pewter industry. Two thirds of medical personnel with hand dermatitis were allergic to rubber gloves. One year follow up after patch testing showed that 19% of patients still suffered from chronic dermatitis. Dermatitis improved in 34% of patients. Forty-seven percent were cured and stopped attending the clinic after patch testing and adequate counselling.

    We reviewed 204 cases of liver abscess seen between 1970 and 1985. Ninety were found to be amoebic, 24 pyogenic and one tuberculous. The cause of the abscesses in the remaining 89 patients was not established. The patients were predominantly male, Indians, and in the 30-60 age group. The majority of patients presented with fever and right hypochondrial pain. The most common laboratory findings were leucocytosis, hypoalbuminaemia and an elevated serum alkaline phosphatase. Amoebic abscesses were mainly solitary while pyogenic abscesses were mainly multiple. Complications were few in our patients and included rupture into the pleural and peritoneal cavities and septicaemic shock. An overall mortality of 2.9% was recorded. The difficulty in diagnosing the abscess type is highlighted. The single most important test in helping us diagnose amoebic abscess, presumably the most common type of abscess in the tropics, is the Entamoeba histolytica antibody assay. This test should be used more frequently in the tropics. PMID:3658864

The rate of superficial and deep wound infections were 11.9% and 1.5% respectively. The most common organism in superficial wound infection was Staphylococcus aureus. The factors that were significantly associated with superficial wound infection were diabetes mellitus (p= 0.0230) obesity (p=0.0088). The patients who developed superficial wound infection have a significantly longer duration of surgery compared to patients without infection (p=0.014). However, there was no significant difference between the mean age among patients with and without superficial wound infection (p=0.814).

    A retrospective study involving 102 adults with dengue haemorrhagic fever (DHF) was conducted to investigate the demographic aspect, clinical presenting features, laboratory investigations, complications, and mortality associated with the disease. The clinical diagnosis of DHF was in accordance with WHO recommendations. Epistaxis, gingivitis, haematemesis and gastritis were among the common complications. Platelet levels tended to decline from a higher value on admission (mean 67,000/mm3) to lower levels on subsequent days, with the lowest (mean 61,000/mm3) being on day 6 of the fever. Hyponatraemia (46.8%) was commonly observed. Morbidity of DHF was significant (29.4%) but the case fatality rate remained low (2.0%) in our adults, suggesting that adults are less likely than children to suffer from shock syndrome.

    This research studies two types of cardiac angiography procedures, namely Computed Tomography Cardiac Angiography (CTCA) and Conventional Angiography (CA). The following research was executed to estimate the difference of mean effective doses that the patients received through both procedures. The mean dose-length-product (DLP) from CTCA and mean dose-area-product (DAP) from CA were utilized in calculating the effective doses. The result shows that the mean effective dose for CTCA and CA are 1.71±0.59 mSv and 53.25±14.22 mSv respectively. This proves that the mean effective dose received by patients undergoing CA is higher than patients undergoing CTCA. According to t-test, both procedures differ significantly, with a difference amounting to p<0.0001. The increases of the effective dose that the patients received through CA procedure were influenced by exposure time, the coronary anatomical condition, the operator's experience, and the operation methods.

    The aim of this retrospective study is to report on the prevalence of post-extraction complications among patients attending the Oral Surgery outpatient clinic of the Faculty of Dentistry, University of Malaya over a 12-month period from January to December, 1992. The prevalence of post-extraction complications which required further treatment was only 3.4% (n = 100), out of a total of 2968 patients who had extraction of one or more permanent teeth. Analysis based on complete clinical reports (n = 79) showed that dry socket accounted for nine out of ten cases of post-extraction complications. However the aetiology was largely unknown. No obvious association with medical history could be made. Lower teeth were more likely to have complications. The most common teeth associated with dry socket were the molars (76%) and premolars (19%). The most common molars to be affected are the first, followed by the third and lastly the second molars. A brief review of current aetiological factors of dry socket was discussed.

    We investigated the prevalence of non-typhoidal Salmonella (NTS) with "reduced susceptibility to ciprofloxacin" (RS-Cip) (minimum inhibitory concentration [MIC], 0.12-1.0 μg/mL) as well as their resistance genes in 75 NTS isolates (53 from stool, 21 from blood, and 1 from urine) from patients at a tertiary care Malaysian hospital between January and December 2009. RS-Cip was detected in 24/75 (32.0%) isolates. Using the ciprofloxacin MIC interpretive criteria for Salmonella in the Clinical and Laboratory Standards Institute 2013 guidelines, 51/75 (68.0%) isolates were found to be sensitive, 22/75 (29.3%) were intermediate, and 2/75 (2.7%) were resistant to ciprofloxacin. The 24 isolates that were intermediate or resistant to ciprofloxacin were the same isolates categorized as having RS-Cip. Among the 23 tested isolates with RS-Cip, the qnrS gene was detected in 17/23 (73.9%) and single gyrA mutations were detected in 6/23 (26.1%) (Asp87Tyr [n = 3], Asp87Asn [n = 2], and Ser83Phe [n = 1]). A parC (Thr57Ser) mutation was detected in 13/23 (56.5%) isolates, coexisting with either a qnrS gene or a gyrA mutation. The high incidence of the qnrS gene among isolates with RS-Cip needs to be monitored because qnr genes can spread via plasmids and aid in the emergence of increased resistance levels.

    The aim of the study was to look into the epidemiology of serodiagnosed cases of leptospirosis at the University Hospital and compare two commercial ELISA Assays to the Microscopic Agglutination Test (MAT). Demographic data for all serodiagnosed cases for the years 1991-1997 were collected. From this data, 104 sera (n = 104) were selected as samples for comparative evaluation of the commercial ELISAs (INDX Dip-S-Ticks and PanBio ELISA) to the MAT test. Thirty two (n = 32) negative control sera were selected from serodiagnosed cases of other differential diagnosis of leptospira infection. The MAT test is a standard test that detects agglutination antibodies to leptospira biflexa, while the INDX Dip-S-Ticks is an ELISA dot test assaying for total anti-leptospira antibodies. The PanBio ELISA is a colorometric assay in test well strips to detect anti-leptospira IgM. The sensitivity, specificity, and efficiency of tests were calculated at a MAT cut-off value of 1:320. Demographic data showed that leptospirosis peaks during March-May and Aug-Nov coinciding with the inter-monsoon period with more men being infected than women and more adults than children. The sensitivity, specificity, and efficiency of test for the INDX Dip-S-Ticks were 83.3%, 93.8% and 87.5% while the values for the PanBio ELISA were 54.2%, 96.9% and 71.3%. The suboptimal PanBio result could be related to the blocking effect of high IgG titres or could be related to the diagnostic MAT cut-off values used in this study. The data hence reflects a pattern of transmission that is related to "wet" occupational risk factors. The commercial assays evaluated, are easier to perform but interpretation of results should be based on level of endemicity. The INDX Dip-S-Ticks allows this flexibility and is a practical alternative to the MAT test.

    A seroepidemiology study was done in response to the recent increase of Endemic Typhus cases diagnosed at University Hospital. The serosurvey was based on doctors' request for the Weil Felix (WF) or the Indirect Immunoperoxidase (IIP) test in Pyrexia of Unknown Origin (PUO) patients for the years 1991 to 1997. Over the 7 years, we found that the incidence of Endemic typhus is increasing with gender (male:female = 2:1), age (20-40 years) and race distribution (Indians > Malay > Chinese) that reflects socioeconomic circumstances. A commercially available ELISA dot assay [INDX (E2R3) Dip-S-Ticks], for the detection of antibodies against R. typhi was compared with the indirect immunoperoxidase test (IIP). The ELISA assay was done against 219 IIP tested sera. The Dip-S-Ticks was found to be comparable to the IIP with a sensitivity of 91.7% and specificity of 92.8% at cut-off titres of > 1:80 IIP.

    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.

    BACKGROUND: Organic Brain Syndromes (OBS) are often missed in clinical practice. Determining their varied presentations may help in earlier detection, better management, and, assessing prognosis and outcome. We described the in-patient referrals of patients suffering from the psychiatric effects of organic states and compared the symptomatology and mortality between those with the Acute and Chronic varieties. METHODS: 59 patients referred to our Consultation-Liaison (C-L) Psychiatry services and given a clinical diagnosis of OBS were selected over a 6-month period. Psychiatric and cognitive abnormalities and treatment regimes were recorded and fatality rates determined. Information regarding their condition 24 months after their index hospitalization was recorded. All data were entered into a proforma and analyzed after exclusion. RESULTS: The mean duration of detecting the symptoms by the physician was 3.52 days. The presence of a premorbid psychiatric illness had no influence on the clinical presentation but did on the mortality of patients with OBS (p = 0.029).Patients with the Acute syndrome had significantly more symptom resolution as compared to those with the Chronic syndrome (p = 0.001) but mortalityrates did not differ. Elderly patients and those with symptom resolution upon discharge did not show statistically significant higher mortality rates. The most popular combination of treatment was that of a low-dose neuroleptic and a benzodiazepine (34.7%). The need for maintenance treatment was not significantly different in any group, even in those with a past history of a functional disorder. CONCLUSION: Other than the Acute group having a significantly better outcome in terms of symptom resolution, our findings suggest that there was no significant difference in the clinical presentation between those with Acute or Chronic OBS. Mortality-wise, there was also no difference between the Acute and Chronic syndromes, nor was there any difference between the elderly and the younger group. There was also no significant difference in the need for continued treatment in both groups.

    Molecular alterations in KRAS, BRAF, PIK3CA, and PTEN have been implicated in designing targeted therapy for colorectal cancer (CRC). The present study aimed to determine the status of these molecular alterations in Malaysian CRCs as such data are not available in the literature. We investigated the mutations of KRAS, BRAF, and PTEN, the gene amplification of PIK3CA, and the protein expression of PTEN and phosphatidylinositol 3-kinase (PI3K) catalytic subunit (p110α) by direct DNA sequencing, quantitative real-time PCR, and immunohistochemistry, respectively, in 49 CRC samples. The frequency of KRAS (codons 12, 13, and 61), BRAF (V600E), and PTEN mutations, and PIK3CA amplification was 25.0% (11/44), 2.3% (1/43), 0.0% (0/43), and 76.7% (33/43), respectively. Immunohistochemical staining demonstrated loss of PTEN protein in 54.5% (24/44) of CRCs and no significant difference in PI3K p110α expression between CRCs and the adjacent normal colonic mucosa (p = 0.380). PIK3CA amplification was not associated with PI3K p110α expression level, but associated with male cases (100% of male cases vs 56% of female cases harbored amplified PIK3CA, p = 0.002). PI3K p110α expression was significantly higher (p = 0.041) in poorly/moderately differentiated carcinoma compared with well-differentiated carcinoma. KRAS mutation, PIK3CA amplification, PTEN loss, and PI3K p110α expression did not correlate with Akt phosphorylation or Ki-67 expression. KRAS mutation, PIK3CA amplification, and PTEN loss were not mutually exclusive. This is the first report on CRC in Malaysia showing comparable frequency of KRAS mutation and PTEN loss, lower BRAF mutation rate, higher PIK3CA amplification frequency, and rare PTEN mutation, as compared with published reports.

    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.

  19. Household Catastrophic Healthcare Expenditure and Impoverishment Due to Rotavirus Gastroenteritis Requiring Hospitalization in Malaysia

    PubMed Central

    2015-01-01

    Background 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. Objectives 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. Methods 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. Results 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). Conclusions While urban households were wealthier, healthcare expenditure due to gastroenteritis had more catastrophic and poverty impact on the urban poor. Universal rotavirus vaccination

  20. Designing a prehospital system for a developing country: estimated cost and benefits.

    PubMed

    Hauswald, M; Yeoh, E

    1997-10-01

    Many of the costs associated with prehospital care in developed countries are covered in budgets for fire suppression, police services, and the like. Determining these costs is therefore difficult. The costs and benefits of developing a prehospital care system for Kuala Lumpur, Malaysia, which now has essentially no emergency medical services (EMS) system, were estimated. Prehospital therapies that have been suggested to decrease mortality were identified. A minimal prehospital system was designed to deliver these treatments in Kuala Lumpur. The potential benefit of these therapies was calculated by using statistics from the United States corrected for demographic differences between the United States and Malaysia. Costs were extrapolated from the current operating budget of the Malaysian Red Crescent Society. Primary dysrhythmias are responsible for almost all potentially survivable cardiac arrests. A system designed to deliver a defibrillator to 85% of arrests within 6 minutes would require an estimated 48 ambulances. Kuala Lumpur has approximately 120 prehospital arrhythmic deaths per year. A 6% resuscitation rate was chosen for the denominator, resulting in seven survivors. Half of these would be expected to have significant neurological damage. Ambulances cost $53,000 (US dollars) to operate per year in Kuala Lumpur; 48 ambulances would cost a total of $2.5 million. Demographic factors and traffic problems would significantly increase the cost per patient. Other therapies, including medications, airway management, and trauma care, were discounted because both their additional cost and their benefit are small. Transport of patients (including trauma) is now performed by police or private vehicle and would probably take longer by ambulance. A prehospital system for Kuala Lumpur would cost approximately $2.5 million per year. It might save seven lives, three of which would be marred by significant neurological injury. Developing countries would do well to

    2015-10-01

    This qualitative study aimed to describe field worker perceptions, evaluations of worth, and time costs of routine dengue vector surveillance methods in Cairns (Australia), Kuala Lumpur and Petaling District (Malaysia). In Cairns, the BG-Sentinel trap is a favored method for field workers because of its user-friendliness, but is not as cost-efficient as the sticky ovitrap. In Kuala Lumpur, the Mosquito Larvae Trapping Device is perceived as a solution for the inaccessibility of premises to larval surveys. Nonetheless, the larval survey method is retained in Malaysia for prompt detection of dengue vectors. For dengue vector surveillance to be successful, there needs to be not only technical, quantitative evaluations of method performance but also an appreciation of how amenable field workers are to using particular methods. Here, we report novel field worker perceptions of dengue vector surveillance methods in addition to time analysis for each method.

    Introduction Glutathione S-transferase (GST) is a xenobiotic metabolising enzyme (XME), which may modify susceptibility in certain ethnic groups, showing ethnic dependent polymorphism. The aim of this study was to determine GSTM1, GSTM3 and GSTT1 gene polymorphisms in a Malaysian population in Kuala Lumpur. Material and methods Blood or buccal swab samples were collected from 137 Form II students from three schools in Wilayah Persekutuan Kuala Lumpur. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results Glutathione-S-transferase GSTM3 gene frequencies were 89% for AA, 10% for AB and 1% for BB. The gene frequencies for deleted GSTM1 and GSTT1 were 66% and 18% respectively. Conclusions This study suggested that the Malay population is at risk for environmental diseases and provides the basis for gene-environment association studies to be carried out. PMID:22291790

    Enhanced index tracking is a popular form of portfolio management in stock market investment. Enhanced index tracking aims to construct an optimal portfolio to generate excess return over the return achieved by the stock market index without purchasing all of the stocks that make up the index. The objective of this paper is to construct an optimal portfolio using mixed-integer programming model which adopts regression approach in order to generate higher portfolio mean return than stock market index return. In this study, the data consists of 24 component stocks in Malaysia market index which is FTSE Bursa Malaysia Kuala Lumpur Composite Index from January 2010 until December 2012. The results of this study show that the optimal portfolio of mixed-integer programming model is able to generate higher mean return than FTSE Bursa Malaysia Kuala Lumpur Composite Index return with only selecting 30% out of the total stock market index components.

    One hundred and thirty-two newly diagnosed Asian diabetic patients (39 Malay, 30 Chinese and 63 Indians) have been studied in Kuala Lumpur. The highest proportion of diabetic patients were Indian and the lowest were Chinese. Vascular complications were equally common in Asian diabetic patients as in Europeans; coronary heart disease was relatively more common in Indians and cerebral vascular disease in Chinese. Twenty percent of all Asian diabetic patients requiring admission to hospital also had coronary heart disease, 9% had cerebral vascular disease and 8% had gangrene or ulceration of the feet. In Kuala Lumpur, diabetes is a very important risk factor for coronary heart disease: 17% of all patients admitted to the General Hospital with coronary heart disease were already diabetic.

    Demographic and drug abuse characteristics of 3,484 new drug abuse contacts presenting to the General Hospital, Kuala Lumpur, Malaysia are reported. The large majority were heroin inhalers. They were different from the traditional Eastern opium inhalers and similar to Western heroin injectors in that they were young, male, single, and frequently unemployed. These features and the relative underrepresentation of Chinese suggest that the Chinese of this study did not learn narcotic abuse from opium-smoking relatives. PMID:7446511

    The occurrence of macroparasites was studied from 543 stray cats in four urban cities from the west (Kuala Lumpur), east (Kuantan), north (Georgetown) and south (Malacca) of Peninsular Malaysia from May 2007 to August 2010. Five ectoparasites species were recovered namely, Ctenocephalides felis, Felicola subrostratus, Haemaphysalis bispinosa, Heterodoxus spiniger and Lynxacarus radovskyi. Two cats from Georgetown were infested with the dog louse, H. spiniger and this represented the first host record for this species in Malaysia. Up to nine species of helminths were recovered with overall high prevalences of infection of 83% in Kuantan, followed by 75.1% in Kuala Lumpur, 71.6% in Georgetown and 68% in Malacca. The helminth species comprised five nematodes, Toxocara malaysiensis, Toxocara cati, Ancylostoma braziliensis, Ancylostoma ceylanicum, Physaloptera praeputialis, two cestodes Taenia taeniaeformis, Dipylidium caninum and one trematode, Playtnosomum fastosum. The majority of helminths were present in the four study sites except for the absence of P. praeputialis in Kuala Lumpur. The prevalence and abundance of infections were analysed taking intrinsic (host age and sex) and extrinsic (season) factors into consideration. Levels of infection and infestation were mainly influenced by host age and to a lesser extent sex and season, whereas four nematode species exhibited significant interactions within the intestine of the cat host. The potential for transmission of some macroparasite species from stray cats to the human population in urban areas is discussed.

    Kami menjalankan beberapa eksperimen aviari untuk mengenal pasti kesan warna ke atas pemilihan kuantiti oleh dua jenis burung, burung gagak (Corvus splendens) dan burung tiung (Acridotheres tristis). Cacing dalam kuantiti berbeza (tujuh pembahagian berlainan) diberikan kepada burung dalam turutan rawak menggunakan cacing dicat dengan warna merah bagi eksperimen 1 dan menggunakan cacing dicat warna hijau bagi eksperimen 2. Kedua-dua warna cacing merah dan hijau tidak memberi kesan kepada pemilihan kuantiti gagak (merah: ANOVA: F6,30 = 1.748, p = 0.144; dan hijau: ANOVA: F6,30 = 1.085, p = 0.394). Namun demikian, burung tiung menunjukkan kesan pengaruh kuat bagi warna merah ke atas pemilihan kuantiti (ANOVA: F6,30 = 2.922, p = 0.023), dengan burung berjaya memilih jumlah makanan yang lebih besar antara dua cawan, tetapi tidak apabila cacing berwarna hijau ditawarkan (ANOVA: F6,30 = 1.183, p = 0.342). Dalam eksperimen seterusnya, hipotesis kami ialah kedua-dua burung gagak dan burung tiung akan memilih makanan berwarna merah berbanding warna hijau apabila faktor jumlah makanan adalah sama. Kami memilih untuk menguji warna merah dan warna hijau kerana kedua-dua warna memainkan peranan penting dalam pemilihan makanan burung. Keputusan menunjukkan tiada perbezaan signifikan bagi pemilihan cacing merah dan hijau bagi kedua-dua burung gagak (ANOVA: F6,30 = 2.310, p = 0.06) dan burung tiung (ANOVA: F6,30 = 0.823, p = 0.561).

    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.

    Generated rain attenuation time series plays an important role for investigating the rain fade characteristics in the lack of real fade measurements. A suitable conversion technique can be applied to measured rain rate time series to produce rain attenuation data and be utilized to understand the rain fade characteristics. This paper focuses on applicability of synthetic storm technique (SST) to convert measured rain rate data to rain attenuation time series. Its performance is assessed for time series generation over a tropical location Kuala Lumpur, in Malaysia. From preliminary analysis, it is found that SST gives satisfactory results to estimate the rain attenuation time series from the rain rate measurements over this region.

    This article investigated the influences of structural breaks on the fractionally integrated time-varying volatility model in the Malaysian stock markets which included the Kuala Lumpur composite index and four major sectoral indices. A fractionally integrated time-varying volatility model combined with sudden changes is developed to study the possibility of structural change in the empirical data sets. Our empirical results showed substantial reduction in fractional differencing parameters after the inclusion of structural change during the Asian financial and currency crises. Moreover, the fractionally integrated model with sudden change in volatility performed better in the estimation and specification evaluations.

    Studies on the urban heat island effects in two adjacent tropical cities, Singapore and Kuala Lumpur, are surveyed. Past efforts have concentrated on surface temperature mapping relying largely on spot measurements, which, although are inadequate, do indicate the existence of warm spots associated with urbanization. Examination of station records have indicated perceptible temperature increases in both cities, though there has been no concerted effort to facilitate comparative studies. Recent work includes implementation of more systematic data acquisition, the use of the remote technology, as well as surface energy balance modelling. Directions for future work is discussed.

    Analytical solutions are presented to the near-neutral atmospheric surface energy balance with the new approach of including the participation of heat storage in the building substrate. Analytical solutions are also presented for the first time for the case without heat storage effect. By a linearization process, the governing equations are simplified to a set of time-dependent, linear, first-order equations from which explicit solutions are readily obtainable. The results compare well with those obtained by numerical solutions upon the set without linearization when applied to the tropical city of Kuala Lumpur, Malaysia.

    William Fletcher's 1905-1906 beriberi experiment with residents of the Kuala Lumpur Lunatic Asylum is the focus of Vollrath's essay on the moral obligations of the scientist. If an experiment harms some subjects (several of Fletcher's patients died), is the scientific integrity of the research consistent with the scientist's moral obligations to those subjects? Do the subjects have the moral right not to be harmed? What are the subjects' moral rights in this context? The author argues that, aside from the issue of using nonconsenting institutionalized subjects, Fletcher's experiment did not violate a moral right of the subjects; moral right is determined prospectively by anticipating risks, not retrospectively by calculating known harms.

    A study on population patterns of the parasitoid Spalangia endius Walker at a dumping ground near Kuala Lumpur city showed that the percentage of S. endius adult emergence varied seasonally. During the relatively heavy rainfall months of August and November 1988, and January, March, and April 1989, the population of S. endius adult emergence were low (0-14.2%) compared to the less rainy months of July, September, and December 1988, and May 1989 (29.3-39.6%). This information could be useful in formulating strategies to reduce house fly population at the refuse dumping ground through integrated pest management programs.

    Screening by culture of endocervical specimens revealed four cases of gonorrhea among 744 pregnant women attending the prenatal clinic at the University Hospital in Kuala Lumpur, Malaysia. The observed prevalence of gonorrhea (0.54%) in pregnant women is similar to that in Great Britain (0.2-0.7%), but lower than the prevalences reported for North America (2.5-7.5%) and Thailand (11.9%). The results indicate that routine screening of pregnant women attending prenatal clinics in Malaysia would aid in the control of gonorrhea in that country. PMID:7256495

    The combined epithelial odontogenic tumour represents a hybrid lesion comprising primarily areas of adenomatoid odontogenic tumour intermixed with foci of calcifying epithelial odontogenic tumour. Five such cases retrieved from the files of the Division of Stomatology, Institute for Medical Research, Kuala Lumpur, and four others from the existing literature were analysed. A mean age of 18.8 years, a female preponderance (66.7%) with a male to female ratio of 1:2 and predilection for the mandible (55.6%) were observed. All cases were treated by conservative surgery and the lack of recurrence confirmed the innocuous nature of this lesion.

    We report an unusual cause of gastrointestinal infection occurring in a 1-year-old infant patient who was brought to a public hospital in Kuala Lumpur, Malaysia. Larvae passed out in the patient’s feces were confirmed by DNA barcoding as belonging to the species, Lasioderma serricorne (F.), known as the cigarette beetle. We postulate that the larvae were acquired from contaminated food and were responsible for gastrointestinal symptoms in the patient. To our knowledge, this the first report of human canthariasis caused by larvae of L. serricorne. PMID:27208008

    An adult Malaysian woman returned to Japan from Kuala Lumpur and had onset of dengue fever-like symptoms including high fever, malaise and arthritis in early January 2009. Serum obtained on the following day was tested at the National Institute of Infectious Diseases in Tokyo, where it was determined to be positive for chikungunya virus (CHIKV) RNA. IgM antibody against CHIKV was negative on January 6 and sero-converted to be positive on January 14, confirming a recent CHIKV infection. Except for arthralgia, all her symptoms resolved uneventfully within 10 days.

    Eight cases of liver failure and encephalopathy were observed among twenty cases of grade 3 and grade 4 dengue hemorrhagic fever/dengue shock syndrome admitted to the Department of Pediatrics, University Hospital, Kuala Lumpur from January 1990 to December 1991. All patients with deterioriation in mental status showed a marked increase in liver enzymes (aspartate and alanine aminotransaminases) and severe coagulopathy. Six patients needed cerebral protection, including ventilation, intravenous sedation and muscle relaxants. There was one death during the period of study and one case of residual hemiparesis in a boy who had, in addition, intracerebral hemorrhage. All other survivors had complete recovery of liver and neurological function.

    Temperature and ozone profiles from SHADOZ (1998-2005) radiosonde and ozonesonde profiles are analyzed. Data from four representative stations are used to investigate regional differences as well as QBO and ENSO influences on vertically fine structure. Principal components of the ozone profile time series at Kuala Lumpur (101°E, 3°N) are adopted as a stratospheric QBO index to study tropospheric temperature and ozone signatures associated with the QBO. A downward propagating QBO ozone signal extends to the mid-troposphere where the phase analysis of the temperature anomalies implies that the driving force is a zonal mean overturning circulation associated with thermal wind adjustment. The maximum tropospheric ozone anomalies associated with the QBO are ≈8 ppbv, about 10-20% that of typical tropical tropospheric ozone values, and differ in phase at the four sites. Temperature and ozone fields, linearly regressed against the QBO index, suggest that dynamical processes, including horizontal transport, play an important role in the observed tropospheric ozone anomalies. Temperature profiles, regressed against the Southern Oscillation Index (SOI), reveal anomalously cool, but also wavy lower stratospheric temperature anomalies over Kuala Lumpur and Nairobi (37°E, 1°S). Tropospheric ozone profiles associated with the SOI show a statistically significant signal that is consistent with anomalous vertical motions that are known to occur during ENSO, but also exhibit fluctuations at a 40-50 day time scale.

    This paper examines using housing supply as proxy to house prices, the causal relationship on house prices among 8 states in Malaysia by applying the Engle-Granger cointegration test and Granger causality test approach. The target states are Perak, Selangor, Penang, Federal Territory of Kuala Lumpur (WPKL or Kuala Lumpur), Kedah, Negeri Sembilan, Sabah and Sarawak. The primary aim of this study is to estimate how long (in months) house prices in Perak lag behind that of Selangor, Penang and WPKL. We classify the 8 states into two categories - developed and developing states. We use Engle-Granger cointegration test and Granger causality test to examine the long run and short run equilibrium relationship among the two categories.. It is found that the causal relationship is bidirectional in Perak and Sabah, Perak and Selangor while it is unidirectional for Perak and Sarawak, Perak and Penang, Perak and WPKL. The speed of deviation adjustment is about 273%, suggesting that the pricing dynamic of Perak has a 32- month or 2 3/4- year lag behind that of WPKL, Selangor and Penang. Such information will be useful to investors, house buyers and speculators.

    The first major Malaysian epidemic of dengue hemorrhagic fever with severe manifestations occurred in 1973, with 969 reported cases and 54 deaths. In a detailed study of 138 clinically diagnosed and laboratory confirmed cases at the General Hospital in Kuala Lumpur, hemorrhagic manifestations were observed in 68.7% and shock in 18.1% of the patients. The cases occurred mainly from May to September, largely in urban and suburban areas of the majority of the states in the country. A main focus of infection was Jinjang, a heavily populated outlying district of Kuala Lumpur, where unusually high incidences of morbidity, severe disease and mortality were seen. Severe disease was seen mostly in children under the age of 15 years, although a significant number of adults suffered milder illnesses. The Chinese population was chiefly affected, due to their living in crowded, low-income housing where the vector, Aedes aegypti, occurred in the greatest numbers. All four dengue types were recovered during the epidemic period, although dengue 3 (DEN-3) was incriminated as the major epidemic type. Entomological data revealed high indices of A. aegypti throughout the country and left little doubt that this epidemic was aegypti transmitted. Spraying and fogging operations were carried out in attempts to control vector populations.

    Magnetic Resonance-guided focused Ultrasound Surgery (MRgFUS) is gaining popularity as an alternative to medical and surgical interventions in the management of symptomatic uterine fibroids. Studies have shown that it is an effective non-invasive treatment with minimal associated risks as compared to myomectomy and hysterectomy. MRgFUS can be offered to a majority of patients suffering from symptomatic uterine fibroids. It has been suggested that the use of broader inclusion criteria as well as the mitigation techniques makes it possible to offer MRgFUS to a much larger subset of patients than previously believed. This paper will describe how MRgFUS treatment for uterine fibroids is performed at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia. PMID:21611036

    Large quantities of mud from the LUSI (Lumpur Sidoarjo) volcano in northeastern Java have been channeled to the sea causing high rates of sediment delivery to the mouth of the Porong River, which has a cover of natural and planted mangroves. This study investigated how the high rates of sediment delivery affected vertical accretion, surface elevation change and the growth of Avicennia sp., the dominant mangrove species in the region. During our observations in 2010-2011 (4-5years after the initial volcanic eruption), very high rates of sedimentation in the forests at the mouth of the river gave rise to high vertical accretion of over 10cmy(-1). The high sedimentation rates not only resulted in reduced growth of Avicennia sp. mangrove trees at the two study sites at the Porong River mouth, but also gave rise to high soil surface elevation gains.

    Malaysia, Singapore, and Vietnam are the only countries in southeast Asia with binding and well-functioning social contracts. The legitimacy of the governments and state bureaucracies in Thailand and Indonesia, and to a certain extent also of those in the Philippines, has been based upon nationalism, high economic growth, and the promotion of social order through coercion or cooptation. However, in order for the management of a city to be successful, its policies need to be conducive to social sustainability, defined as development compatible with the emergence of a social contract which both fosters an environment which will help to harmonize relations between the city's culturally and socially diverse groups, yet encourages social integration and an improvement in the lives of all of its citizens. These concerns are discussed with regard to Jakarta, Bangkok, Manila, and Kuala Lumpur. PMID:12295213

    A study of completed in-patient suicides at the University Hospital Kuala Lumpur (UHKL) and Hospital Bahagia Ulu Kinta (HBUK) between 1st January 1967 to 31st December 1987 were conducted. Records of completed in-patient suicides during the period were exhaustively studied. Only 18 cases were from UHKL and 23 cases were from HBUK. It was found that the suicide patients were mainly young Chinese males from the lower socio economic group. The main reasons for suicide were interpersonal conflicts and physical illness. Alcohol was not an important factor unlike patients in the West.. Suicidal intent was also important. Many of the suicides were committed during the early hours of the morning and they usually occurred at inaccessible places. The method was strongly influenced by availability. To the best knowledge of the author, this is the first study of in-patient suicides in Malaysia. PMID:1839422

    A survey of 4.112 primary school children living in and around Kuala Lumpur, Malaysia, revealed that 12.9% of the children were infested with Pediculus humanus capitis. Indians (28.3%) and Malays (18.9%) have a higher prevalence than Chinese (4.6%). The higher prevalence among Indians and Malays correlates well with their lower socio-economic status in the community; long hair also contributes to the higher rates of pediculosis among them. The prevalence rate was found to be related to socio-economic status, length of hair, family size, age, crowding and personal hygiene. Treatment with 0.2% and 0.5% malathion in coconut oil gave cure rates of 93% and 100%. Treatment with gammexane and actellic at 0.5% concentration gave a cure rate of 100% against adults and nymphs of Pediculus humanus capitis.

    Entomological surveillance was conducted in order to determine the abundance and to evaluate any changes of biological vectors or ecology, especially in the dengue outbreak areas. The abundance and breeding preference of Aedes albopictus and Aedes aegypti were conducted in selected dengue outbreak localities in three states of peninsular Malaysia namely Selangor, Federal Territory of Kuala Lumpur, and Penang Island using ovitraps and larval survey method. It was determined that Ae. albopictus was predominant in most of the localities and found to breed more outdoor than indoor. A wide range of breeding foci were recorded in this study. It was also determined that ovitrap method was more effective to detect the presence of Aedes mosquitoes when the larval survey was at low rate of infestation. The abundance of Ae. albopictus in dengue outbreak localities emphasis that the vector control programme should also target this species together with the primary dengue vector, Ae. aegypti.

    Wahid Murad, M. D.; Siwar, Chamhuri

    This study has developed three Logistic Regression Models to determine and analyze the factors that could affect knowledge, attitude and behavior of the urban poor concerning solid waste management. To pursue the objective, the study has collected primary data from the level of living conditions of the poor residing in the squatters and low-cost flats of Kuala Lumpur city, Malaysia. The empirical results of the study are exciting as they provide evidence to the effect that knowledge, attitude and behavior of the urban poor communities concerning solid waste management are adequate and satisfactory. Hence, the low socio-economic profile of the urban poor has not been proven as causal to environmental degradation. The study suggests that it is inherent to improve the quality of lifestyles of the poor to enable them to come out of poverty threshold, even though an adequate and satisfactory solid waste management system exists amongst the communities.

    Public transport in crowded cities, in particular bus services play an essential role in the mobility of its citizenry. However, an efficient, reliable and safe bus system is still a distant dream of many cities. This paper uses a simulation approach to provide some insight into the factors that contribute to the service quality of a bus system. SAS Simulation Studio is used to model a city bus route. The simulation model consists of a bus depot, bus stops, terminal station and a bus route. Parameters used in the simulation include the number of buses serving the route, maximum bus capacity, inter departure time of buses, travel time between stops, number of passengers boarding and alighting. The simulation is applied to a real bus route in Kuala Lumpur city center and a sensitivity analysis is performed to evaluate how the different variables affect the service quality of the bus system.

    The study is the first research in Malaysia that investigates user acceptance of Internet banking service (IBS) based on Unified Theory of Acceptance and Use of Technology model (Venkatesh, Morris, Davis and Davis, 2003). Two hundred and eighty questionnaires were distributed and collected from two major cities, Kuala Lumpur and Melaka. Descriptive statistics was used to analyse the data. The results show that Malaysians have intentions of using IBS (mean rating of close to 4.00). Moreover, Malaysians recognize the benefits of IBS by giving a high mean rating (close to 4.00) to performance expectancy. However, they give relative low mean ratings (close to 3.00) on other indicators of Behavioural Intention to Use IBS such as effort expectancy, social influence, facilitating conditions and perceived credibility. Recommendations were given to promote a safe, efficient and conducive environment for user adoption of Internet banking.

    In this study, a dynamic behaviour of a solar powered single stage four bed adsorption chiller has been analysed designed for Malaysian climate. Silica gel and water have been used as adsorbent-refrigerant pair. A simulation program has been developed for modeling and performance evaluation of the chiller using the meteorological data of Kuala Lumpur. The optimum cooling capacity and coefficient of performance (COP) are calculated in terms of adsorption/desorption cycle time and regeneration temperature. Results indicate that the chiller is feasible even when low temperature heat source is available. Results also show that the adsorption cycle can achieve a cooling capacity of 14 kW when the heat source temperature is about 85°C.

    Index tracking is an investment strategy in portfolio management which aims to construct an optimal portfolio to generate similar mean return with the stock market index mean return without purchasing all of the stocks that make up the index. The objective of this paper is to construct an optimal portfolio using the optimization model which adopts regression approach in tracking the benchmark stock market index return. In this study, the data consists of weekly price of stocks in Malaysia market index which is FTSE Bursa Malaysia Kuala Lumpur Composite Index from January 2010 until December 2013. The results of this study show that the optimal portfolio is able to track FBMKLCI Index at minimum tracking error of 1.0027% with 0.0290% excess mean return over the mean return of FBMKLCI Index. The significance of this study is to construct the optimal portfolio using optimization model which adopts regression approach in tracking the stock market index without purchasing all index components.

    This study assessed the economic value of health impacts of transboundary smoke haze pollution in Kuala Lumpur and adjacent areas in the state of Selangor, Malaysia. Daily inpatient data from 2005, 2006, 2008, and 2009 for 14 haze-related illnesses were collected from four hospitals. On average, there were 19 hazy days each year during which the air pollution levels were within the Lower Moderate to Hazardous categories. No seasonal variation in inpatient cases was observed. A smoke haze occurrence was associated with an increase in inpatient cases by 2.4 per 10,000 populations each year, representing an increase of 31 percent from normal days. The average annual economic loss due to the inpatient health impact of haze was valued at MYR273,000 ($91,000 USD).

    An indirect enzyme linked immunosorbent assay (ELISA) was developed for the diagnosis of allergy to a house dust mite, Dermatophagoides farinae. The efficacy of the ELISA was then evaluated against a prick test using a commercial allergen. Eighty five suspected allergic rhinitis patients from the Otorhinolaryngology Department, Kuala Lumpur General Hospital, were tested with the ELISA and prick test. Prick test and ELISA results were positive in 84.7% and 80.0% of the patients respectively. The ELISA was found to have 87.5% sensitivity, 61.5% specificity, 92.6% positive predictive value, 47.1% negative predictive value, 7.4% false positive and 52.9% false negative. There was total agreement between the prick test and ELISA for prick test grades of 3+ and 4+. It is concluded that the ELISA is a useful assay for detection of individuals who are highly sensitive to D. farinae.

    Three cases of spontaneous Cerebrospinal Fluid (CSF) rhinorrhea were managed at the National University Hospital, Kuala Lumpur. Case 1 had bilateral leak secondary to empty sella syndrome and the rest two cases had unilateral leak. Four transnasal endoscopic approaches were performed on these three cases since March 1999. The role of intrathecal Sodium Fluorescein is highlighted in localising the CSF fistula. Case 3 required postoperative lumbar drain as an adjunct. No recurrent leak was noted on post operative follow up in Case 2 and 3 ranging from nine to thirty two months. A recurrent left leak at six months was noted in Case 1 which could likely be due to her sudden bout of cough attacks and patient refused further surgical intervention. PMID:12733180

    The pattern of infant feeding practice was studied among Malay mothers in Kg. Sentosa, a squatter community in Kuala Lumpur. Breastmilk only was provided by most mothers up to the 4th week, after which it was increasingly replaced by cow's milk. 95% of the working mothers and 54% of the full-time housewives had introduced bottle-feeding supplemented with precooked cereal and porridge by 2 months of age. Factors related to maternal employment, household income and occurrence of illness in child affect significantly the duration of exclusive breastfeeding. Variability in the timing of commencement and completion of weaning could be attributed partially only (42.1% and 26.8% respectively) to the household, maternal and child variables taken together. This seems to imply that personal reasons largely govern decisions related to feeding infants. (Author's). PMID:12342397

    Drawing on the lived experiences of the Pengkids and their girlfriends in the deprived district of the capital city of Malaysia, Kuala Lumpur, this article examines transgender practices and women's same-sex desires within the local contexts of urbanization and political Islam. This article questions the assumed marginal positions of transgender practices and same-sex desires in society, and provides a nuanced understanding of the politics of identity, gender, sexuality and religion involved in a Muslim country. While the Muslim-Malay sexual minorities are increasingly subjected to the threats of moral policing in Malaysia, Pengkid has become a new identity marker for the marginalized sexual subject framed by the Islamic discourse of this country.

    2016-06-01

    The Drive for Muscularity Scale (DMS) is a widely used measure in studies of men's body image, but few studies have examined its psychometric properties outside English-speaking samples. Here, we assessed the factor structure of a Malay translation of the DMS. A community sample of 159 Malay men from Kuala Lumpur, Malaysia, completed the DMS, along with measures of self-esteem, body appreciation, and muscle discrepancy. Exploratory factor analysis led to the extraction of two factors, differentiating attitudes from behaviours, which mirrors the parent scale. Both factors also loaded on to a higher-order drive for muscularity factor. The subscales of the Malay DMS had adequate internal consistencies and good convergent validity, insofar as significant relationships were reported with self-esteem, body appreciation, muscle discrepancy, and body mass index. These results indicate that the Malay DMS has acceptable psychometric properties and can be used to assess body image concerns in Malay men. PMID:27037873

    2008-01-01

    Malaysia has a long history of medical education, with Singapore becoming the first medical school to serve the region after its foundation in 1905. The first school to be established in Kuala Lumpur after independence from the British was the Faculty of Medicine at the University of Malaya in 1963. Whilst today there are 21 public and private medical schools, all offering a 5 year undergraduate programme, some private schools have diversified by developing international collaboration and conduct twinning or credit-transfer programmes. All medical schools require accreditation by the National Accreditation Board and the Malaysian Medical Council. Although the criteria for accreditation is comprehensive and covers a broad range of areas of assessment, it is debatable whether it always matches the needs of the country. The dramatic increase in medical schools in the last two decades has posed challenges in terms of maintenance of quality, physical infrastructure and suitably qualified faculty.

    1986-04-14

    During the 10-year period 1974-1983, 68 patients with intraperitoneal haemorrhage as a result of the rupture of a corpus luteum were managed at the University Hospital, Kuala Lumpur, Malaysia. Most of the patients were aged between 18 and 35 years. In 63% of the patients the rupture occurred between the 14th and the 35th day of the menstrual cycle, and 10 patients had intraperitoneal bleeding severe enough (450-1500 mL) to require blood transfusion. The condition is often confused with other surgical emergencies such as appendicitis and ectopic pregnancy. An increased awareness of the problem in women of reproductive age and the use of laparoscopy, when indicated, will allow a more conservative approach to be adopted for those patients with minimal bleeding. The performance of an appendicectomy in the presence of blood in the peritoneal cavity did not appear to increase morbidity in those patients with a preoperative diagnosis of "appendicitis".

    1983-01-01

    This article descripes the compilation and analysis of basic perinatal statistics in the Maternity Hospital, Kuala Lumpur (MHKL), the largest maternity hospital in the country. The study period covered is 1980-1. Because consented autopsies are difficult to obtain in the social and religious setting of Malaysia, the approach of clinical classification of causes of neonatal deaths was adopted. Determinants of neonatal mortality included very low birthweight (less than 1.5kg), gestational age of less than 32 weeks, and clinical conditions of asphyxia, meconium aspiration syndrome, bacterial sepsis, and respiratory distress syndrome. The resulting charts underscore how simple neonatal data can be compiled to assess perinatal performance in a way which requires little statistical sophistication. Accurate perinatal statistics will enable better comprehension of preventable causes of perinatal deaths, and enhanced outcomes. Wider application of this approach is recommended in hospitals throughout Malaysia.

    Health care workers have been reported to constitute one of the few high-risk groups related to IgE-mediated hypersensitivity associated with the use of latex products. This paper describes the first ever study of prevalence carried out in Malaysia among these workers. One hundred and thirty health care personnel from Hospital Kuala Lumpur were skin tested. Extracts used were prepared from seven different brands of natural rubber latex gloves with varying levels of extractable protein (EPRRIM). Out of the 130 volunteers, 4 (3.1%) had positive skin test to latex with extracts with high levels of EPRRIM (> 0.7 mg/g). The prevalence among the Malaysian health care workers can be considered to be low in comparison to that of some consumer countries as the USA which reported a prevalence of as high as 16.9%.

    Investors wish to achieve the target rate of return at the minimum level of risk in their investment. Portfolio optimization is an investment strategy that can be used to minimize the portfolio risk and can achieve the target rate of return. The mean-variance model has been proposed in portfolio optimization. The mean-variance model is an optimization model that aims to minimize the portfolio risk which is the portfolio variance. The objective of this study is to construct the optimal portfolio using the mean-variance model. The data of this study consists of weekly returns of 20 component stocks of FTSE Bursa Malaysia Kuala Lumpur Composite Index (FBMKLCI). The results of this study show that the portfolio composition of the stocks is different. Moreover, investors can get the return at minimum level of risk with the constructed optimal mean-variance portfolio.

    Enhanced index tracking is a popular form of passive fund management in stock market. It is a dual-objective optimization problem, a trade-off between maximizing the mean return and minimizing the risk. Enhanced index tracking aims to generate excess return over the return achieved by the index without purchasing all of the stocks that make up the index by establishing an optimal portfolio. The objective of this study is to determine the optimal portfolio composition and performance by using weighted model in enhanced index tracking. Weighted model focuses on the trade-off between the excess return and the risk. The results of this study show that the optimal portfolio for the weighted model is able to outperform the Malaysia market index which is Kuala Lumpur Composite Index because of higher mean return and lower risk without purchasing all the stocks in the market index.

    The development of neurosurgical services and training in Malaysia began in 1963, with the first centre established in its capital city at Hospital Kuala Lumpur, aimed to provide much needed neurosurgical services and training in the field of neurology and neurosurgery. This center subsequently expanded in 1975 with the establishment of the Tunku Abdul Rahman Neuroscience Institute (IKTAR); which integrated the three allied interdependent disciplines of neurosurgery, neurology and psychiatry. The establishment of this institute catalysed the rapid expansion of neurosurgical services in Malaysia and paved the way for development of comprehensive training for doctors, nurses, and paramedics. This culminated in the establishments of a local comprehensive neurosurgery training program for doctors in 2001; followed by a training program for nurses and paramedics in 2006. To date, there are more than 60 neurosurgeons providing expert care in 11 centers across Malaysia, along with trained personnel in the field of neurosciences. PMID:27006632

    The semi-culture of marine bivalves particularly Anadara granosa is of considerable economic importance in Malaysia. Currently, about 4-5000 ha of mudflats along the west coast are utilized for this purpose. Therefore, contamination of the highly productive mudflats with heavy metals tend to be accumulated in the filter feeding organisms such as bivalve molluscs which often serve as important environmental sinks of heavy metals. Bivalve molluscs, A. granosa and Paphia undulata are commercially important seafoods and popular among the locals in Malaysia. With this point in mind, it is intended to evaluate the concentration levels of arsenic as well as trace metals (Co, Cu, Ni, Cd, Zn, Cr and Pb) in both species derived from retail outlets in the city of Kuala Lumpur. Although this analysis may not indicate the site of capture but may act as a direct check on the contamination of seafoods available to the consumers. 17 refs., 2 tabs.

    Tuberculosis of the genital tract was diagnosed in only 12 patients during the 17 year period from March 1968 to February 1985 at the University Hospital, Kuala Lumpur, which serves as a major referral centre in Malaysia. The incidence was 0.31 per 1000 gynaecological admissions and the peak age incidence was in the age group 26 to 35 years. The surgical management was mainly conservative as infertility was the most frequent mode of presentation (50%). Evidence of previous pulmonary tuberculosis was present in only five cases. Adnexal adhesions were the commonest pelvic finding; the fallopian tubes and endometrium were affected with equal frequency. Positive cultures for Mycobacterium tuberculosis were obtained in only five of the 12 patients. All patients received combination anti-tuberculosis drugs with satisfactory response.

    Genetic counseling service is urgently required in developing countries. In Malaysia, the first medical genetic service was introduced in 1994 at one of the main teaching hospitals in Kuala Lumpur. Two decades later, the medical genetic services have improved with the availability of genetic counseling, genetic testing and diagnosis, for both paediatric conditions and adult-onset inherited conditions, at four main centers of medical genetic services in Malaysia. Prenatal diagnosis services and assisted reproductive technologies are available at tertiary centres and private medical facilities. Positive developments include governmental recognition of Clinical Genetics as a subspecialty, increased funding for genetics services, development of medical ethics guidelines, and establishment of support groups. However, the country lacked qualified genetic counselors. Proposals were presented to policy-makers to develop genetic counseling courses. Challenges encountered included limited resources and public awareness, ethical dilemmas such as religious and social issues and inadequate genetic health professionals especially genetic counselors.

    Dengue fever is major public health problem especially among the highly urbanized states of Malaysia, such as, Selangor and Kuala Lumpur Federal Territory. We report an epidemiological cluster pattern of dengue outbreak in the district of Gombak, Selangor that may mimic other acute febrile illnesses in which the transmission mode is via close contact. This dengue outbreak consisted of two waves; an initial cluster of three cases (including the first deceased, JI) which occurred between 20th and 21st of July, followed by a later larger cluster of 11 cases that occurred between 1st and 8th of August 2005. This epidemiological clustering pattern of acute dengue virus infection among close contacts suggests an intense rate of dengue virus transmission within the vicinity of the first deceased's house.

    Malaysia, Singapore, and Vietnam are the only countries in southeast Asia with binding and well-functioning social contracts. The legitimacy of the governments and state bureaucracies in Thailand and Indonesia, and to a certain extent also of those in the Philippines, has been based upon nationalism, high economic growth, and the promotion of social order through coercion or cooptation. However, in order for the management of a city to be successful, its policies need to be conducive to social sustainability, defined as development compatible with the emergence of a social contract which both fosters an environment which will help to harmonize relations between the city's culturally and socially diverse groups, yet encourages social integration and an improvement in the lives of all of its citizens. These concerns are discussed with regard to Jakarta, Bangkok, Manila, and Kuala Lumpur.

    An anthropometric assessment was conducted on a sample of 309 children, aged twelve years and below, from an urban squatter community in Kuala Lumpur, Malaysia. The community consists mainly of Malays and Indians and is fairly established with a mean length of residence of about fifteen years. There was not much difference between the two ethnic groups with regard to educational status or income. Most of the residents were unskilled or semiskilled workers employed in factories and government agencies. About 40 percent of the infants and toddlers were found to be wasted, while about one-third of the older children were stunted. There appears to be some association between income per capita and nutritional status.

    The tsunami which occurred off the west coast of North Sumatra on December 26, 2004 devastated the coastal areas of North Sumatra, South-West Thailand, South-East India and Sri Lanka killing more than a quarter of a million people. The destruction was enormous with many coastal villages destroyed. The other countries affected were Malaysia, Myanmar, Maldives, Bangladesh, Somalia, Kenya, Tanzania and the Seychelles. In January 2005, volunteers went in weekly rotation to Banda Aceh in collaboration with Global Peace Mission. These were Dr Hyzan Yusof, Dr Suryasmi Duski, Dr Sharaf Ibrahim, Dr Saw Aik, Dr Kamariah Nor and Dr Nor Azlin. In Banda Aceh, the surgical procedures that we could do were limited to external fixation of open fractures and debriding infected wounds at the Indonesian Red Crescent field hospital. In February, a team comprising Dato Dr K S Sivananthan, Dr T Kumar and Dr S Vasan spent a week in Sri Lanka. In Sri Lanka, Dato Sivananthan and his team were able to perform elective orthopaedic operations in Dr Poonambalam Memorial Hospital. We appealed for national and international aid and received support from local hospitals and the orthopaedic industry. International aid bound for Banda Aceh arrived in Kuala Lumpur from the Philippine Orthopaedic Association, the Chiba Children's Hospital in Japan and the Chinese Orthopaedic Association. The COA donated 1.5 tons of orthopaedic equipments. A special handing over ceremony from the COA to the Indonesian Orthopaedic Association was held in Putrajaya in March. Malaysia Airlines flew in the donated equipment to Kuala Lumpur while the onward flight to Aceh was provided by the Royal Malaysian Air Force. In April, Dr Saw Aik and Dr Yong Su Mei joined the Tsu-Chi International Medical Association for volunteer services on Batam Island, Indonesia. The MOA acknowledges the many individuals and organizations, both governmental and non-governmental, for their contributions in the humanitarian efforts.

    Enterovirus A71 (EV-A71), which is transmitted by the fecal-oral route, causes hand, foot and mouth disease and, rarely, severe neurological complications. In Malaysia, the indigenous rural community (Orang Asli) has a high prevalence of parasitic diseases due to poor sanitation, water supply and hygiene practices. This cross-sectional study compared the seroepidemiology of EV-A71 among rural Orang Asli and urban Kuala Lumpur populations in West Malaysia, and determined the risk factors associated with EV-A71 seropositivity in rural Orang Asli. Seropositive rates were determined by neutralization assay. EV-A71 seropositivity was strongly associated with increasing age in both populations. Rural Orang Asli children ≤12 years had significantly higher EV-A71 seropositivity rates than urban Kuala Lumpur children (95.5% vs 57.6%, P < 0.001), and also higher rates in the age groups of 1-3, 4-6 and 7-12 years. Multivariate analysis confirmed that age ≤12 years (adjusted OR 8.1, 95% CI 3.2-20.7, P < 0.001) and using untreated water (adjusted OR 6.2, 95% CI 2.3-16.6, P < 0.001) were independently associated with EV-A71 seropositivity in the Orang Asli population. Supply of clean drinking water may reduce the risk of EV-A71 infection. With significantly higher EV-A71 seropositive rates, younger rural children should be a priority target for future vaccination programs in Malaysia. PMID:26866912

    Biomass burning activities in Southeast Asia have become a major concern of general public as well as governments in the region. This is because that aerosols emitted from such fires can cause long-lasting haze events under favorite weather conditions in downwind locations such as Singapore, degrading air quality and causing human health issues. In order to improve our understanding of the spatiotemporal coverage and influence of biomass burning aerosols in Southeast Asia, we have used the Weather Research and Forecasting (WRF) model with a smoke aerosol module to conduct multi-year simulations covering the period from 2002 to 2014, driven by the biomass burning emissions from the Fire INventory from NCAR (FINN) version 1.5. To attribute the aerosol influences over various target regions to specific fire locations, we have also partitioned aerosols emitted from five major fire regions of Southeast Asia in the simulations. Based on the simulation results, we have examined the influences of various meteorological regimes on the aerosol transport and wet removal. We find that the transport and scavenging of biomass burning aerosols are strongly modulated by the Southeast Asian monsoon wind field and precipitation. We also identified that in the past decade, smoke aerosols are responsible for a substantial fraction of low visibility events in the major metropolitan areas of the region: 35% in Bangkok, 25% in Kuala Lumpur, 16% in Singapore, and 22% in Jakarta. The fires in the Indochina peninsula account for the largest percentage of the total fire enhancement to PM2.5 in Bangkok (98.9%), and fires in Sumatra were the major contributor in Kuala Lumpur (49%), Singapore (39%), and Jakarta (48%).

    In many parts of Southeast Asia, the HIV-1 epidemic has been driven by the sharing of needles and equipment among intravenous drug users (IDUs). Over the last few decades, many studies have proven time and again that the diversity of HIV-1 epidemics can often be linked to the route of infection transmission. That said, the diversity and complexity of HIV-1 molecular epidemics in the region have been increasing at an alarming rate, due in part to the high tendency of the viral RNA to recombine. This scenario was exemplified by the discovery of numerous circulating recombinant forms (CRFs), especially in Thailand and Malaysia. In this study, we characterized a novel CRF designated CRF74_01B, which was identified in six epidemiologically unlinked IDUs in Kuala Lumpur, Malaysia. The near-full length genomes were composed of CRF01_AE and subtype B', with eight breakpoints dispersed in the gag-pol and nef regions. Remarkably, this CRF shared four and two recombination hotspots with the previously described CRF33_01B and the less prevalent CRF53_01B, respectively. Genealogy-based Bayesian phylogenetic analysis of CRF74_01B genomic regions showed that it is closely related to both CRF33_01B and CRF53_01B. This observation suggests that CRF74_01B was probably a direct descendent from specific lineages of CRF33_01B, CRF53_01B and subtype B' that could have emerged in the mid-1990s. Additionally, it illustrated the active recombination processes between prevalent HIV-1 subtypes and recombinants in Malaysia. In summary, we report a novel HIV-1 genotype designated CRF74_01B among IDUs in Kuala Lumpur, Malaysia. The characterization of the novel CRF74_01B is of considerable significance towards the understanding of the genetic diversity and population dynamics of HIV-1 circulating in the region.

  17. Investigating the haze transport from 1997 biomass burning in Southeast Asia: its impact upon Singapore

    NASA Astrophysics Data System (ADS)

    Koe, Lawrence C. C.; Arellano, Avelino F.; McGregor, John L.

    The 1997 Indonesia forest fires was an environmental disaster of exceptional proportions. Such a disaster caused massive transboundary air pollution and indiscriminate destruction of biodiversity in the world. The immediate consequence of the fires was the production of large amounts of haze in the region, causing visibility and health problems within Southeast Asia. Furthermore, fires of these magnitudes are potential contributors to global warming and climate change due to the emission of large amounts of greenhouse gases and other pyrogenic products.The long-range transport of fire-related haze in the region is investigated using trajectories from the CSIRO Division of Atmospheric Research Limited Area Model (DARLAM). Emission scenarios were constructed for hotspot areas in Sumatra and Kalimantan for the months of September and October 1997 to determine the period and fire locations most critical to Singapore. This study also examines some transport issues raised from field observations. Results show that fires in the coastal areas of southeast Sumatra and southwest Kalimantan can be potential contributors to transboundary air pollution in Singapore. Singapore was directly affected by haze from these areas whereas Kuala Lumpur was heavily affected by the haze coming from Sumatra. In most cases, Singapore was more affected by fires from Kalimantan than was Kuala Lumpur. This was mainly a result of the shifting of monsoons. The transition of monsoons resulted in weaker low-level winds and shifted convergence zones near to the southeast of Peninsular Malaysia. In addition to severe drought and massive fire activity in 1997, the timing of the monsoon transition has a strong influence on haze transport in the region.

That said, the diversity and complexity of HIV-1 molecular epidemics in the region have been increasing at an alarming rate, due in part to the high tendency of the viral RNA to recombine. This scenario was exemplified by the discovery of numerous circulating recombinant forms (CRFs), especially in Thailand and Malaysia. In this study, we characterized a novel CRF designated CRF74_01B, which was identified in six epidemiologically unlinked IDUs in Kuala Lumpur, Malaysia. The near-full length genomes were composed of CRF01_AE and subtype B', with eight breakpoints dispersed in the gag-pol and nef regions. Remarkably, this CRF shared four and two recombination hotspots with the previously described CRF33_01B and the less prevalent CRF53_01B, respectively. Genealogy-based Bayesian phylogenetic analysis of CRF74_01B genomic regions showed that it is closely related to both CRF33_01B and CRF53_01B. This observation suggests that CRF74_01B was probably a direct descendent from specific lineages of CRF33_01B, CRF53_01B and subtype B' that could have emerged in the mid-1990s. Additionally, it illustrated the active recombination processes between prevalent HIV-1 subtypes and recombinants in Malaysia. In summary, we report a novel HIV-1 genotype designated CRF74_01B among IDUs in Kuala Lumpur, Malaysia. The characterization of the novel CRF74_01B is of considerable significance towards the understanding of the genetic diversity and population dynamics of HIV-1 circulating in the region.

    A workshop was held December 9 in Kathmandu to introduce participants to three innovative information, education and communication materials developed for China with funds from UNFPA/JOICFP. This workshop was a follow-up to two others held early in 1993 in Kuala Lumpur and Tokyo. The first workshop focused upon printed educational materials for preadolescent girls, while the second was aimed at producing video scripts for women's health. The deputy director and secretary general of the Shanghai International Center for Population Communication, China, introduced the participants to the eight types of menstrual record cards produced for pre-adolescent girls and two videos, one for STD prevention and one for AIDS prevention. Aimed at encouraging girls to accept and better understand their reproductive cycles, the menstrual record cards have been distributed to young girls in Shanghai. They were produced from several prototypes created at the Kuala Lumpur workshop and with information from a knowledge, attitude, and practice survey conducted among school girls in Shanghai. The STD video was broadcast nationwide on China Central TV before the workshop, while the AIDS video was broadcast on World AIDS Day on December 1 in Shanghai and Yunnan. The second part of the workshop focused upon the experiences of the Mexican Foundation for Family Planning (MEXFAM) which has been promoting an adolescent health program. The third part of the workshop offered a video developed by a Vietnamese nongovernmental organization designed to raise women's self-esteem. Another recently produced JOICFP video on Asia was presented, while participants were given a demonstration of a prototype for a new easier to carry, simpler, and cheaper version of the educational Magnel Kit.

    Fang, M.; Zheng, M.; Wang, F.; To, K. L.; Jaafar, A. B.; Tong, S. L.

    The large-scale air pollution episode due to the out-of-control biomass burning for agricultural purposes in Indonesia started in June 1997, has become a severe environmental problem for itself and the neighboring countries. The fire lasted for almost five months. Its impact on the health and ecology in the affected areas is expected to be substantial, costly and possibly long lasting. Air pollution Index as high as 839 has been reported in Malaysia. API is calculated based on the five pollutants: NO 2, SO 2, O 3, CO, and respirable suspended particulates (PM10). It ranges in value from 0 to 500. An index above 101 is considered to be unhealthy and a value over 201 is very unhealthy (Abidin and Shin, 1996). The solvent-extractable organic compounds from four total suspended particulate (TSP) high-volume samples collected in Kuala Lumpur, Malaysia (Stations Pudu and SIRIM) were subjected to characterization - the abundance was determined and biomarkers were identified. Two of the samples were from early September when the fire was less intense, while the other two were from late September when Kuala Lumpur experienced very heavy smoke coverage which could be easily observed from NOAA/AVHRR satellite images. The samples contained mainly aliphatic hydrocarbons such as n-alkanes and triterpanes, alkanoic acids, alkanols, and polycyclic aromatic hydrocarbons. The difference between the early and late September samples was very significant. The total yield increased from 0.6 to 24.3 μg m -3 at Pudu and 1.9 to 20.1 μg m -3 at SIRIM, with increases in concentration in every class. The higher input of vascular plant wax components in the late September samples, when the fire was more intense, was characterized by the distribution patterns of the homologous series n-alkanes, n-alkanoic acids, and n-alkanols, e.g., lower U : R, higher >C 22/C 20/

    Short-lived organic brominated compounds make up a significant part (~20%) of the organic bromine budget in the atmosphere. Emissions of these compounds are highly variable and there are limited measurements, particularly in the extra-tropical upper troposphere/lower stratosphere and tropical troposphere. Measurements of five short-lived bromomethanes (VSLB) were made in air samples collected on the CARIBIC project aircraft over three flight routes; Germany to Venezuela/Columbia during 2009-2011, Germany to South Africa during 2010 and 2011 and Germany to Thailand/Kuala Lumpur, Malaysia during 2012 and 2013. In the tropical troposphere, as the most important entrance region to the stratosphere, we observe a total mean organic bromine derived from these compounds across all flights at 10-12 km altitude of 3.4 ± 1.5 ppt. Individual mean tropical tropospheric mixing ratios across all flights were 0.43, 0.74, 0.14, 0.23 and 0.11 ppt for CHBr3, CH2Br2, CHBr2Cl, CHBrCl2 and CH2BrCl respectively. The highest levels of VSLS-derived bromine (4.20 ± 0.56 ppt) were observed in flights between Bangkok and Kuala Lumpur indicating that the South China Sea is an important source region for these compounds. Across all routes, CHBr3 and CH2Br2 accounted for 34% (4.7-71) and 48% (14-73) respectively of total bromine derived from the analysed VSLB in the tropical mid-upper troposphere totalling 82% (54-89). In samples collected between Germany and Venezuela/Columbia, we find decreasing mean mixing ratios with increasing potential temperature in the extra-tropics. Tropical mean mixing ratios are higher than extra-tropical values between 340-350 K indicating that rapid uplift is important in determining mixing ratios in the lower tropical tropopause layer in the West Atlantic tropics. O3 was used as a tracer for stratospherically influenced air and we detect rapidly decreasing mixing ratios for all VSLB above ~100 ppb O3 corresponding to the extra-tropical tropopause layer.

    Background Tuberculosis (TB) still constitutes a major public health problem in Malaysia. The identification and genotyping based characterization of Mycobacterium tuberculosis complex (MTBC) isolates causing the disease is important to determine the effectiveness of the control and surveillance programs. Objectives This study intended a first assessment of spoligotyping-based MTBC genotypic diversity in Malaysia followed by a comparison of strains with those prevailing in neighboring countries by comparison with an international MTBC genotyping database. Methods Spoligotyping was performed on a total of 220 M. tuberculosis clinical isolates collected in Kelantan and Kuala Lumpur. The results were compared with the SITVIT2 international database of the Pasteur Institute of Guadeloupe. Results Spoligotyping revealed 77 different patterns: 22 corresponded to orphan patterns while 55 patterns containing 198 isolates were assigned a Spoligo International Type (SIT) designation in the database (the latter included 6 newly created SITs). The eight most common SITs grouped 141 isolates (5 to 56 strains per cluster) as follows: SIT1/Beijing, n = 56, 25.5%; SIT745/EAI1-SOM, n = 33, 15.0%; SIT591/EAI6-BGD1, n = 13, 5.9%; SIT256/EAI5, n = 12, 5.5%; SIT236/EAI5, n = 10, 4.6%; SIT19/EAI2-Manila, n = 9, 4.1%; SIT89/EAI2-Nonthaburi, n = 5, 2.3%; and SIT50/H3, n = 3, 1.4%. The association between city of isolation and lineages was statistically significant; Haarlem and T lineages being higher in Kuala Lumpur (p<0.01). However, no statistically significant differences were noted when comparing drug resistance vs. major lineages, nor between gender and clades. Conclusions The ancestral East-African-Indian (EAI) lineage was most predominant followed by the Beijing lineage. A comparison of strains with those prevailing in neighboring countries in South Asia, East Asia and South East Asia underlined the phylogeographical specificity of SIT745 for

    The uptake of naturally occurring thorium, radium and potassium by sawi (Japanese Mustard) from disused tin mining was studied. Both soil and sawi sample were collected from a vegetable farm located 15 km from Kuala Lumpur, Malaysia where the farm has been operating for 22 years on a disused tin mining. By using a gamma spectroscopy system, the transfers of radionuclides from soil to plants were investigated. The highest values of radionuclides in the soil was K-40 which is 52.8 Bq kg-1 and the lowest was Ra-226 which is 6.51 Bq kg-1. The activity of Th-232 is 18.5 Bq kg-1. The activity of radionuclides in the sawi sample shows higher values as compared to the soil sample. The highest values of radionuclides in the sawi were K-40 which is 446 Bq kg-1 and the lowest was Ra-226 which is 17.5 Bq kg-1. The activity of Th-232 is 65.2 Bq kg-1. The concentration of radionuclides in soils and plants can be used for the determination of soil-to-plant transfer factors. The soil to plant transfer factors (TF) were calculated and observed to be 2.68 for radium-226, 3.52 for thorium-232 and the highest which is 3.97 for potassium-40.

    Plasmodium knowlesi is extensively used as an important malaria model and is now recognized as an important cause of human malaria in Malaysia. The strains of P. knowlesi currently used for research were isolated many decades ago, raising concerns that they might no longer be representative of contemporary parasite populations. We derived a new P. knowlesi line (University Malaya line, UM01), from a patient admitted in Kuala Lumpur, Malaysia, and compared it with a human-adapted laboratory line (A1-H.1) derived from the P. knowlesi H strain. The UM01 and A1-H.1 lines readily invade human and macaque (Macaca fascicularis) normocytes with a preference for reticulocytes. Whereas invasion of human red blood cells was dependent on the presence of the Duffy antigen/receptor for chemokines (DARC) for both parasite lines, this was not the case for macaque red blood cells. Nonetheless, differences in invasion efficiency, gametocyte production and the length of the asexual cycle were noted between the two lines. It would be judicious to isolate and characterise numerous P. knowlesi lines for use in future experimental investigations of this zoonotic species. PMID:27097521

    The aims were to investigate the prevalence of mild cognitive impairment (MCI) within gender disparities in Malaysian older adults, and to determine the predictors of MCI according to gender disparities. A community-based sample of urban, multiethnic dwelling elderly aged 60 years of age and above from Cheras, Kuala Lumpur was recruited. Prevalence of all-type MCI, amnestic-type MCI (am-MCI) and non-amnestic-type MCI (nam-MCI) was assessed using comprehensive neuropsychological batteries. The association between demography, socioeconomic status, lifestyle practices, and nutritional status and health risk factors with MCI were examined. Predictors of MCI occurrence between gender disparities were determined. The prevalence of all-type MCI, am-MCI and nam-MCI was 21.1%, 15.4% and 5.7%, respectively. Binary logistic regression indicated that hypercholesterolemia is the significant predictor for MCI in men after adjustment for age, ethnicity and total years of education. While, in women, MCI was best predicted by married status, without exercise practice, overweight and obesity. These results suggest that approximately one-fifth of the studied elderly people had MCI. Predictors for MCI are totally different between men and women. It is critical to identify those at higher risk for MCI in order to implement preventative measures to delay or reverse this abnormal condition. PMID:21546098

    This paper presents the mechanical function and characterization of an artificial lightweight geopolymer aggregate (ALGA) using LUSI (Sidoarjo mud) and alkaline activator as source materials. LUSI stands for LU-Lumpur and SI-Sidoarjo, meaning mud from Sidoarjo which erupted near the Banjarpanji-1 exploration well in Sidoarjo, East Java, Indonesia on 27 May 2006. The effect of NaOH molarity, LUSI mud/Alkaline activator (LM/AA) ratio, and Na2SiO3/NaOH ratio to the ALGA are investigated at a sintering temperature of 950 °C. The results show that the optimum NaOH molarity found in this study is 12 M due to the highest strength (lowest AIV value) of 15.79% with lower water absorption and specific gravity. The optimum LUSI mud/Alkaline activator (LM/AA) ratio of 1.7 and the Na2SiO3/NaOH ratio of 0.4 gives the highest strength with AIV value of 15.42% with specific gravity of 1.10 g/cm3 and water absorption of 4.7%. The major synthesized crystalline phases were identified as sodalite, quartz and albite. Scanning Electron Microscope (SEM) image showed more complete geopolymer matrix which contributes to highest strength of ALGA produced.

    A study was undertaken to 1) determine the effects of tobacco smoke exposure on maternal and neonatal weight and body mass index (BMI) and placental weight, volume and surface area and 2) establish any correlations between the placental surface area, volume and weight with maternal and neonatal body weight and BMI in mothers exposed to cigarette smoke. A total of 154 full-term placentae, 65 from mothers exposed to tobacco smoke and 89 from non-exposed mothers were collected from Kuala Lumpur Maternity Hospital. The placental surface area was determined using a stereological grid, the volume by Scherle's method and the weight by using an electronic weighing machine. In general there were no differences in maternal, placental and neonatal parameters between the exposed and non-exposed groups. However, there were significant correlations between placental weight with maternal weight and maternal BMI in both exposed (r = 0.315; p = 0.013) and (r = 0.265; p = 0.038), and non-exposed (r = 0.224; p = 0.035) and (r = 0.241; p = 0.023) mothers. It was also found that the maternal weight on admission correlated significantly with placental weight in both Malay (r = 0.405; p = 0.020) and Indian (r = 0.553; p = 0.050) passive smokers. Correcting the placental parameters for the maternal weight had no effect on the results. PMID:16379184

    Promoting green design, construction, reconstruction and operation of buildings has never been more critical than now due to the ever increasing greenhouse gas emissions and rapid urbanizations that are fuelling climate change more quickly. Driven by environmental needs, Green Building Index (GBI) was founded in Malaysia to drive initiative to lead the property industry towards becoming more environment-friendly. Green roof system is one of the assessment criteria of this rating system which is under category of sustainable site planning and management. An extensive green roof was constructed in Humid Tropics Center (HTC) Kuala Lumpur as one of the components for Stormwater Management Ecohydrology (SME) in order to obtain scientific data of the system. This paper evaluates the performance of extensive green roof at Humid Tropics Center with respect to urban heat island mitigation and stormwater quantity and quality controls. Findings indicate that there was a reduction of around 1.5°C for indoor temperature of the building after installation of green roof. Simulations showed that the peak discharge was reduced up to 24% relative to impervious brown roof. The results show an increment of pH and high concentration of phosphate for the runoff generated from the green roof and the runoff water quality ranged between class I and II under INWQS.

    Numerical simulation technique was used for investigating water seepage problem at the Botanic Park Kuala Lumpur. A proposed sub-drains installation in problematic site location was simulated using Modular Three-Dimensional Finite Difference Groundwater Flow (MODFLOW) software. The results of simulation heads during transient condition showed that heads in between 43 m (water seepage occurred at level 2) until 45 m (water seepage occurred at level 4) which heads measurement are referred to mean sea level. However, elevations measurements for level 2 showed the values between 41 to 42 m from mean sea level and elevations for level 4 between 42 to 45 m from mean sea level. These results indicated an increase in heads for level 2 and level 4 between 1 to 2 m when compared to elevations slope at the level 2 and level 4. The head increases surpass the elevation level of the slope area that causing water seepage at level 2 and level 4. In order to overcome this problems, the heads level need to be decrease to 1 until 2 m by using two options of sub-drain dimension size. Sub-drain with the dimension of 0.0750 m (diameter), 0.10 m (length) and using 4.90 m spacing was the best method to use as it was able to decrease the heads to the required levels of 1 to 2 m.

    Biweekly ovitrap surveillance (OS) was conducted for a year (August 2007 - September 2008) at two different dengue endemic sites in Shah Alam, Selangor, Malaysia, 50 km from Kuala Lumpur. Aedes aegypti collected from these 2 locations were raised to the F3 stage and subjected to a WHO standard bioassay method to determine lethal time (LT) against pyrethroids (permethrin 0.75%, cyfluthrin 0.15%), organophosphates (malathion 5.0%, fenitrothion 1.0%), carbamates (propoxur 0.1%, bendiocarb 0.1%) and organochlorine (DDT 4.0%). Insecticide susceptibilities were analyzed for one year. Aedes aegypti were resistant to DDT with a mortality range of 0 - 13.3% throughout the year at both sites. Susceptibilities to pyrethroids and carbamates varied throughout the year. In contrast, susceptibilities to pyrethroids and carbamates varied throughout the year: resistant to propoxur, bendiocarb and permethrin with mortality of < 80% in most months; but, showed incipient resistant to cyfluthrin in most months. Mosquitoes were consistently susceptible to malathion and fenitrothion, with complete mortality during most months. They were especially susceptible to malathion with LT50 values of 21.32 - 36.37 minutes, suggesting effectiveness of malathion for control of dengue. PMID:23082552

    Use of quality measurement tools is gaining an attention in the industry and also outside of the industry to improve quality and productivity. In this study, two out of seven quality measurement tools have been applied in determining the quality of drinking water in Malaysia during the year 2010. This study is conducted to measure the nonconformance of drinking water parameter by using p control chart and also to know which states are beyond the control limit. Performance of all states including Federal Territory of Kuala Lumpur, Putrajaya and Labuan are measured in this study by applying Pareto chart and control chart. Pareto chart is used to identify the states which contribute to the proportion of non-conformance while p control chart is used to determine the states that are out of process control. Five parameters of drinking water identified to be the focus of this study are aluminium, chlorine residual, E.coli and chlorine residual, E.coli as well as turbidity. Analysis of variance (ANOVA) and post-hoc test are also being undertaken to identify states that contribute to the significance of mean between states by referring to multiple comparison tables. Results show that there are several states that still recorded out of control limit. As such, the quality of drinking water in these states should be further improved.

    Fossils from the Cambrian to Devonian rocks of southern Thailand, the Langkawi Islands, mainland Kedah, Perlis, north Perak and central West Peninsular Malaysia are listed and reviewed, and their stratigraphy and correlation reassessed. The hitherto anomalous record of the trilobite Dalmanitina from Malaysia is reviewed and found to be of latest Ordovician (Hirnantian) age, rather than Lower Silurian age as previously reported, and is considered a probable synonym of the widespread Mucronaspis mucronata. A new stratigraphical nomenclature is erected for part of the Langkawi, mainland Kedah and Perlis area successions, in which the term Setul Limestone (which stretched from the Ordovician to the Devonian) is abandoned and replaced by the Middle Ordovician Kaki Bukit Limestone, the late Ordovician and early Silurian Tanjong Dendang Formation, the Silurian Mempelam Limestone, and the early Devonian Timah Tasoh Formation, all underlying the paraconformity with the late Devonian Langgun Red Beds. There was a single depositional basin in the generally shallow-water and cratonic areas of southern Thailand, Langkawi, and mainland Kedah and Perlis, in contrast to the deeper-water basin of north Perak. Only Silurian rocks are dated with certainty within another basin in central West Malaysia, near Kuala Lumpur, which were also cratonic and shallow-water, although to the east in west Pahang there are basal Devonian deeper-water sediments with graptolites. The area is reviewed in its position within the Sibumasu Terrane, which, in the Palaeozoic, also included central and northern Thailand, Burma (Myanmar) and southwest China (part of Yunnan Province).

    Sediment trapping of the synthetic construction site stormwater runoff (SCSSR) by grassed filter strip (GFS) was studied in a laboratory flume with simulated GFS of different slopes and bed surface areas. The polynomial regression model of average rainfall density depended rainfall duration has been approved by Malaysian Storm Water Management Manual. Still the relationship between either stormwater runoff flow rate or sediment trapping efficiency and rainfall duration needs to be verified. This study proposes the use of the empirical equations to determine the SCSSR flow rate and to estimate the efficiency of the GFS models to trap sediment based on the rainfall duration. All the parameters in equations have physical meanings, and experimental data validation showed that the equations are sufficiently accurate. The stormwater runoff flow rate and efficiency of the GFS models were verified for the SCSSR originally coming from a construction site of Kuala Lumpur city. New approaches to investigate the hydrological behaviour of construction site are presented and have significant implications for the ability of stormwater flow to carry sediment.

    Normal mixture distributions model has been successfully applied in financial time series analysis. In this paper, we estimate the return distribution, value at risk (VaR) and conditional value at risk (CVaR) for monthly and weekly rates of returns for FTSE Bursa Malaysia Kuala Lumpur Composite Index (FBMKLCI) from July 1990 until July 2010 using the two component univariate normal mixture distributions model. First, we present the application of normal mixture distributions model in empirical finance where we fit our real data. Second, we present the application of normal mixture distributions model in risk analysis where we apply the normal mixture distributions model to evaluate the value at risk (VaR) and conditional value at risk (CVaR) with model validation for both risk measures. The empirical results provide evidence that using the two components normal mixture distributions model can fit the data well and can perform better in estimating value at risk (VaR) and conditional value at risk (CVaR) where it can capture the stylized facts of non-normality and leptokurtosis in returns distribution.

    Knowledge of rainfall-runoff response for urban engineering practices is of pivotal importance, especially for humid tropic areas such as Malaysia where the information is rather limited. In view of this, a rainfall-runoff analysis study was conducted for the 25 km2 urban catchment of Kayu Ara, Kuala Lumpur. Five-minute rainfall and runoff data from 1996 - 2005 were used, from which 146 events were selected for detailed analysis. The relationship between direct runoff and mean areal rainfall provided information on the catchment response. The derived event-based runoff coefficients are useful for catchment comparison, and in particular to understand how different landscapes affect transformation of rainfall into event runoff and to explain the runoff generation mechanism. However, the lack of a standard method for hydrograph separation is a disadvantage, which introduces uncertainty into the analysis and the results and may also complicate comparison with results from other areas. Nevertheless, it is shown that event-based runoff coefficients could improve our understanding of rainfall-runoff response, especially for urban conditions.

  19. Dynamics of short rainfall storms in a small scale urban area in Coly Limper, Malaysia

    Desa, M. N. M.; Niemczynowicz, J.

    Short term storm rainfalls are recorded with a dense network of fine resolution rain gauges well distributed in a small urban catchment in Kuala Lumpur, Malaysia. The period of data collection covers the south-west monsoon (July-September), inter monsoon (October) and partly the north-east monsoon (November-December) seasons. This paper presents some findings with reference to the dynamic properties of short rainfall storms using the method of vector analysis and farther correlation analysis. Good accuracy of data and good synchronisation between the gauges have been achieved thus a meaningful interpretation of the obtained results was made possible. The selected 30 storms have been used to determine the velocities and direction of movement of the storm cells. A correlation study was undertaken to relate the calculated storm velocities and directions with the observed wind velocities and directions from different altitudes. Results show that statistically significant correlation was achieved between the calculated storm velocities and the hourly mean surface wind velocities. In contrast to studies carried out in other climate zones, no significant correlations were obtained between observed storm velocities and directions on ground level versus high altitude measured wind velocities and directions. The average maximum intensities has been found to be correlated with the average storm depths.

    The objective of this paper is to exploit the potential application of an evidential belief function model to landslide susceptibility mapping at Kuala Lumpur city and surrounding areas using geographic information system (GIS). At first, a landslide inventory map was prepared using aerial photographs, high resolution satellite images and field survey. A total 220 landslides were mapped and an inventory map was prepared. Then the landslide inventory was randomly split into a testing dataset 70% (153 landslides) and remaining 30% (67 landslides) data was used for validation purpose. Fourteen landslide conditioning factors such as slope, aspect, curvature, altitude, surface roughness, lithology, distance from faults, ndvi (normalized difference vegetation index), land cover, distance from drainage, distance from road, spi (stream power index), soil type, precipitation, were used as thematic layers in the analysis. The Dempster-Shafer theory of evidence model was applied to prepare the landslide susceptibility maps. The validation of the resultant susceptibility maps were performed using receiver operating characteristics (ROC) and area under the curve (AUC). The validation results show that the area under the curve for the evidential belief function (the belief map) model is 0.82 (82%) with prediction accuracy 0.75 (75%). The results of this study indicated that the EBF model can be effectively used in preparation of landslide susceptibility maps.

    Urban growth has negative environmental impacts that create water-based disasters such as flash floods and storm runoff causing billions of dollars worth of damage each year. Due to serious flash floods in urbanised areas of Malaysia, water resource management is a vital issue. This paper reports on a study that has been carried out using remote sensing techniques and hydrological modelling for examining the spatial patterns changes of urban areas and its impacts on surface runoff. The estimation of surface runoff based on the Soil Conservation Service Curve Number (SCS CN) method was performed by integrating both remote sensing and Geographic Information System (GIS) techniques. Remote sensing is a data sources for monitoring urban growth by quantifying the changes of urban area and its environmental impact are then analysed by using a GIS-based hydrological model. By linking the integrated approach of remote sensing and GIS, the relationship of runoff with urban expansion are further examined. Hence, the changes in runoff due to urbanisation are analysed. This methodology is applied to the central region of Malaysia in Kuala Lumpur, where rapid urban growth has occurred over the last decade. The results showed that there was a significant between spatial patterns of urban growth and estimated runoff depth. The increase in runoff from year 2000, 2006 and 2010 are estimated about five percent.

    This paper intents to investigate the indifferent behaviour quantitatively of target objects of interest due to specular and diffuse reflectivity based on generated LiDAR DSM of the study site in Ampang, Kuala Lumpur. The LiDAR data to be used was initially checked for its reliability and accuracy. The point cloud LiDAR data was converted to raster to allow grid analysis of the next process of generating the DSM and DTM. Filtering and masking were made removing the features of interest (i.e. building and tree) and other unwanted above surface features. A normalised DSM and object segmentation approach were conducted on the trees and buildings separately. Error assessment and findings attained were highlighted and documented. The result of LiDAR verification certified that the data is reliable and useable. The RMSE obtained is within the tolerance value of horizontal and vertical accuracy (x, y, z) i.e. 0.159 m, 0.211 m 0.091 m respectively. Building extraction inclusive of roof top based on slope and contour analysis undertaken indicate the capability of the approach while single tree extraction through aspect analysis appears to preserve the accuracy of the extraction accordingly. The paper has evaluated the suitable methods of extracting non-ground features and the effective segmentation of the LiDAR data.

    Measurements of PM10 and water-soluble ions were carried out on indoor and outdoor PM10 (particles > 10 μm in aerodynamic diameter) aerosols sampled at selected primary schools of Kuala Lumpur (S1) and Putrajaya (S2), respectively. Samples were collected using a low volume sampler on Teflon filters. The water-soluble ions chloride (Cl-), nitrate (NO3-), sulfate (SO42-), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+) and ammonium (NH4+) was analyzed using ion chromatography. The results showed that the indoor PM10 mass concentrations in S1 and S2 were 96.6 and 69.5 μg/m3, while the outdoor PM10 mass concentrations were 80.1 and 85.2 μg/m3, respectively. This indicated that NO3- were the most dominant ions, followed by SO42-, Ca2+, K+ and Na+, while Cl-, Mg2+ and Na+ were present at low concentrations. Pearson's correlation test applied to all the data showed high correlation between SO42- and NO3-, indicating a common anthropogenic origin. In addition, the correlations between Na+ and Ca2+ indicated crustal origins that significantly contributed to human exposure.

  4. Composition of extractable organic matter of air particles from malaysia: Initial study

    The solvent extractable compounds of airborne particulate samples, which were collected on two occasions in a suburb of Kuala Lumpur, Malaysia, with a standard high-volume air sampler, were investigated to determine the distributions of homologous and biomarker compounds. These preliminary results show that both samples contain n-alkanes, n-alkanoic acids and n-alkanols as the dominant solvent-extractable components, with minor amounts of n-alkanedioic acids, n-alkanones, terpenoids, sterols, and phthalate contaminants, derived from biogenic sources (vascular plant wax) and from anthropogenic utilization of fossil fuel products (lubricating oil, vehicle fuels, etc.). Some compositional differences are observed in the two samples and greater atmospheric concentrations were found for almost all organic components in the sample collected under hazy conditions. This is interpreted to be due to the local build-up of organic contaminants as a result of atmospheric stability during the haze episode, to atmospheric photochemical reactions, and to some unidentified anthropogenic activities which are peculiar to the city. Some of the organic components are also suspected to be brought in from areas outside the region.

  5. Magnesium and calcium in carbonate bedrock and groundwaters, Peninsular Malaysia

    NASA Astrophysics Data System (ADS)

    Crowther, J.

    Groundwaters draining Kuala Lumpur Limestone, Kinta Limestone and limestones of the Setul Formation were monitored over a 1 yr period. The closeness of the mean Mg:Ca + Mg ratios of the groundwaters (12.8%) and bedrock (13.3%) indicates calcium and magnesium dissolution to be broadly congruent. Ratios < 2.5and> 35% are much less common in groundwaters than in bedrock because of: (i) heterogeneity in bedrock mineralogy within groundwater catchments; (ii) differential solubilities of calcium and magnesium in calcites, high magnesium calcites and dolomites; and (iii) preferential precipitation of calcium in secondary carbonate deposits. In groundwaters with variable discharges, Mg:Ca + Mg correlates negatively with discharge, as calcium deposition per unit volume of water diminishes at higher flows. Use of groundwater survey data to locate areas of dolomitization and make specific inferences about the mineralogy of limestone formations is discussed, and estimates of net chemical denudation rates (range, 56.6-70.9m 3/km 2/yr) are presented.

    On May 29, 2006, mud and gases began erupting unexpectedly from a vent 150 meters away from a hydrocarbon exploration well near Sidoarjo, East Java, Indonesia. The eruption, called the LUSI (Lumpur 'mud'-Sidoarjo) mud volcano, has continued since then at rates as high as 160,000 m3 per day. At the request of the United States Department of State, the U.S. Geological Survey (USGS) has been providing technical assistance to the Indonesian Government on the geological and geochemical aspects of the mud eruption. This report presents initial characterization results of a sample of the mud collected on September 22, 2007, as well as inerpretive findings based on the analytical results. The focus is on characteristics of the mud sample (including the solid and water components of the mud) that may be of potential environmental or human health concern. Characteristics that provide insights into the possible origins of the mud and its contained solids and waters have also been evaluated.

  7. Female labour force participation and fertility.

    The levels of labor force participation by women in selected Asian countries were recorded in a series of censuses taken over a period of years. These levels were less influenced than male employment levels by economic conditions and more influenced by cultural traits of the country. Postwar trends seem to have fallen in Korea, risen in Singapore and the Philippines, and remained steady in Japan, Malaya, and Thailand. The limitations of these data are mentioned. In Thailand and West Malaysia greater percentages of women worked in agricultural than non-agricultural employment; in the Philippines, where women did not work so much in agricultural pursuits, their jobs were still in traditional rather than in development industries. In the cities of Bangkok, Manila, and Kuala Lumpur, fertility was lower for working than for non-working women. In rural agricultural areas, the fertility of working women was minimally higher, probably due to economic need of lar ger families. It is concluded that urban life separates the employment and the family roles of working women, leading to lowered fertility; this does not occur in rural areas. The creation of new roles for women alternative or supplementary to marriage and motherhood would result in lowered fertility. In high fertility Asian countries, policies directed toward greater participation of women in non-agricultural work and great er exposure to an urban lifestyle might achieve fertility reductions.

    Human metapneumovirus (HMPV) is an important viral respiratory pathogen worldwide. Current knowledge regarding the genetic diversity, seasonality and transmission dynamics of HMPV among adults and children living in tropical climate remains limited. HMPV prevailed at 2.2% (n = 86/3,935) among individuals presented with acute respiratory tract infections in Kuala Lumpur, Malaysia between 2012 and 2014. Seasonal peaks were observed during the northeast monsoon season (November-April) and correlated with higher relative humidity and number of rainy days (P < 0.05). Phylogenetic analysis of the fusion and attachment genes identified the co-circulation of three known HMPV sub-lineages, A2b and B1 (30.2% each, 26/86) and B2 (20.9%, 18/86), with genotype shift from sub-lineage B1 to A2b observed in 2013. Interestingly, a previously unrecognized sub-lineage of A2 was identified in 18.6% (16/86) of the population. Using a custom script for network construction based on the TN93 pairwise genetic distance, we identified up to nine HMPV transmission clusters circulating as multiple sub-epidemics. Although no apparent major outbreak was observed, the increased frequency of transmission clusters (dyads) during seasonal peaks suggests the potential roles of transmission clusters in driving the spread of HMPV. Our findings provide essential information for therapeutic research, prevention strategies, and disease outbreak monitoring of HMPV. PMID:27279080

    Analysis of the bleeding manifestations of 130 cases of dengue haemorrhagic fever admitted into the Children's ward of the General Hospital, Kuala Lumpur from May 1973 to September 1978 has been done. Petechial skin rash, epistaxis and gum bleeding were seen most commonly in mild and moderately severe cases. However, blood stained gastric aspirates, and severe haematemesis were seen in severe or very severe cases. Though with better vector control and preventive measures, a marked reduction in the incidence of the cases has been noted, severe cases were seen with symptoms of shock and gastrointestinal bleeding. These symptoms carried a bad prognosis. Among 15 children that died 10 had gastrointestinal bleeding and 2 had a disseminated intravascular coagulation defect. Lymphocytosis with atypical lymphocytes, low platelet count, low reticulocyte count and raised packed cell volume were the main haematological features seen in all these cases. All these features reverted to normal within a week. Mild evidence of disseminated intravascular coagulation was seen in a number of cases, but severe features were seen only in four. Two cases improved as a result of heparin therapy. PMID:6111919

    Transboundary haze episodes caused by seasonal forest fires have become a recurrent phenomenon in Southeast Asia, with serious environmental, economic, and public health implications. Here we present a cross-sectional survey conducted among people in Kuala Lumpur and surrounds to assess the links between knowledge, attitudes, and practices in relation to the transboundary haze episodes. Of 305 respondents, 125 were amateur athletes participating in a duathlon event and the remainder were surveyed in an inner-city shopping mall. Across the whole sample, people who possessed more factual information about the haze phenomenon showed significantly higher levels of concern. Duathletes were more knowledgeable than non-duathletes and also more concerned about the negative effects of haze, especially on health. For all people who regularly practice outdoor sports (including people interviewed at the shopping mall), higher levels of knowledge and concerned attitudes translated into a greater likelihood of engaging in protective practices, such as cancelling their outdoor training sessions, while those with greater knowledge were more likely to check the relevant air pollution index on a daily basis. Our results indicate that the provision of accurate and timely information about air quality to residents will translate into beneficial practices, at least among particularly exposed individuals, such as amateur athletes who regularly practice outdoor sports.

    Measles is a highly communicable, acute viral illness with potential for severe complications, including death. Although endemic measles was eliminated in the United States in 2000 as a result of widespread vaccination, sporadic measles outbreaks still occur, largely associated with international travel from measles-endemic countries and pockets of unvaccinated persons. On August 26, 2011, the Los Angeles County Department of Public Health (LACDPH) was notified of suspected measles in a refugee from Burma who had arrived in Los Angeles, California, on August 24, after a flight from Kuala Lumpur, Malaysia. Passengers on the flight included 31 other refugees who then traveled to seven other states, widening the measles investigation and response activities. In California alone, 50 staff members from LACDPH and the California Department of Public Health (CDPH) interviewed and reinterviewed 298 contacts. Measles was diagnosed in three contacts of the index patient (patient A). The three contacts with measles were two passengers on the same flight as patient A and a customs worker; no secondary cases were identified. Delayed diagnosis of measles in patient A and delayed notification of health officials precluded use of measles-mumps-rubella (MMR) vaccine as an outbreak intervention. This outbreak emphasizes the importance of maintaining a high level of vaccination coverage and continued high vigilance for measles in the United States, particularly among incoming international travelers; clinicians should immediately isolate persons with suspected measles and promptly report them to health authorities.

    According to BPLS (Badan Penanggulangan Lumpur Sidoarjo) which is the Sidoarjo Mudflow Management Agency, land subsidence occurred in Porong, Sidoarjo was caused by the rocks bearing capacity decreasing which led by the mud outpouring since 2006. The subsidence varies in many ways depends on the radius of location from the mud flow center point and the geological structure. One of the most efficient technologies to monitor this multi temporal phenomenon is using the Synthetic Aperture Radar (SAR) as an applicative Spatial Geodesy. This study used 4 (four) times series L-Band ALOS PALSAR from 2008 to 2011 Fine Beam Single data (February 2008, January 2009 and February 2010 and January 2011) which then processed by the Differential SAR Interferometry (DInSAR) method to obtain the deformation vector at a radius of 1.5 km from the center of mudflow. The result showed that there was a significant subsidence which annually occurred on southern and western area of Sidoarjo mud flow. The deformation vector that occurred in the year 2008-2011 was up to 20 cm/year or 0.05 cm/day. For verification purpose, we also compared the result obtained from the SAR detection with the data measured by Global Position System (GPS) and some deformation monitoring results obtained from another researchs. The comparison showed a correlation that the subsidence occurred on the same location.

    A member of the International Council on Management of Population Programs (ICOMP) says that training women to manage and harbor employable skills has a very large multiplier effect. An international nongovernmental organization (NGO) based in Kuala Lumpur and established in 1973 to improve the performance of family planning programs in Asian developing countries through better management techniques, ICOMP boasts 35 developing countries as members. The organization's mandate has expanded over the years such that they now provide management and skills training programs through local NGOs in developing countries. The Asian Development Bank (ADB) has been assisting ICOMP's training programs in Bangladesh, Indonesia, Nepal, Pakistan, and the Philippines since 1989 with two technical assistance grants totalling $681,000. This is the first time that the Bank has supported training exclusively for women. Although the ADB planned to reach only 940 women under the first technical assistance, it eventually helped train more than 1200; an additional 1300 women have attended the courses offered under the Bank's second grant. Training courses are aimed at disadvantaged women who need training in employment skills, women engaged in community development or income-generating projects who need to develop basic management skills, and officials of the participating women NGOs who need training in organizing, developing, and implementing income-generating projects. The author discusses other elements of training aimed at improving the social and economic status of women, along with experiences of the Bangladesh Association for Community Education and the MELATI Foundation of Jakarta, Indonesia.

    Background This is a pilot cross sectional study using both quantitative and qualitative approach towards tutors teaching large classes in private universities in the Klang Valley (comprising Kuala Lumpur, its suburbs, adjoining towns in the State of Selangor) and the State of Negeri Sembilan, Malaysia. The general aim of this study is to determine the difficulties faced by tutors when teaching large group of students and to outline appropriate recommendations in overcoming them. Findings Thirty-two academics from six private universities from different faculties such as Medical Sciences, Business, Information Technology, and Engineering disciplines participated in this study. SPSS software was used to analyse the data. The results in general indicate that the conventional instructor-student approach has its shortcoming and requires changes. Interestingly, tutors from Medicine and IT less often faced difficulties and had positive experience in teaching large group of students. Conclusion However several suggestions were proposed to overcome these difficulties ranging from breaking into smaller classes, adopting innovative teaching, use of interactive learning methods incorporating interactive assessment and creative technology which enhanced students learning. Furthermore the study provides insights on the trials of large group teaching which are clearly identified to help tutors realise its impact on teaching. The suggestions to overcome these difficulties and to maximize student learning can serve as a guideline for tutors who face these challenges. PMID:21902839

    A yeast-like organism was isolated from the skin scraping sample of a stasis dermatitis patient in the Mycology Unit Department of Medical Microbiology, University Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia. The isolate produced no pigment and was not identifiable using chromogenic agar and API 20C AUX. The fungus was identified as Metschnikowia sp. strain UM 1034, which is close to that of Metschnikowia drosophilae based on ITS- and D1/D2 domain-based phylogenetic analysis. However, the physiology of the strain was not associated to M. drosophilae. This pathogen exhibited low sensitivity to all tested azoles, echinocandins, 5-flucytosine and amphotericin B. This study provided insight into Metschnikowia sp. strain UM 1034 phenotype profiles using a Biolog phenotypic microarray (PM). The isolate utilized 373 nutrients of 760 nutrient sources and could adapt to a broad range of osmotic and pH environments. To our knowledge, this is the first report of the isolation of Metschnikowia non-pulcherrima sp. from skin scraping, revealing this rare yeast species as a potential human pathogen that may be misidentified as Candida sp. using conventional methods. Metschnikowia sp. strain UM 1034 can survive in flexible and diverse environments with a generalist lifestyle. PMID:27280438

    The rate of organ donations from deceased donors in Malaysia is among the lowest in the world. This may be because of the passivity among health professionals in approaching families of potential donors. A questionnaire-based study was conducted amongst health professionals in two tertiary hospitals in Kuala Lumpur, Malaysia. Four hundred and sixty-two questionnaires were completed. 93.3% of health professionals acknowledged a need for organ transplantation in Malaysia. 47.8% were willing to donate their organs (with ethnic and religious differences). Factors which may be influencing the shortage of organs from deceased donors include: nonrecognition of brainstem death (38.5%), no knowledge on how to contact the Organ Transplant Coordinator (82.3%), and never approaching families of a potential donor (63.9%). There was a general attitude of passivity in approaching families of potential donors and activating transplant teams among many of the health professionals. A misunderstanding of brainstem death and its definition hinder identification of a potential donor. Continuing medical education and highlighting the role of the Organ Transplant Coordinator, as well as increasing awareness of the public through religion and the media were identified as essential in improving the rate of organ donations from deceased donors in Malaysia.

    Deaths due to plastic bag suffocation or plastic bag asphyxia are not reported in Malaysia. In the West many suicides by plastic bag asphyxia, particularly in the elderly and those who are chronically and terminally ill, have been reported. Accidental deaths too are not uncommon in the West, both among small children who play with shopping bags and adolescents who are solvent abusers. Another well-known but not so common form of accidental death from plastic bag asphyxia is sexual asphyxia, which is mostly seen among adult males. Homicide by plastic bag asphyxia too is reported in the West and the victims are invariably infants or adults who are frail or terminally ill and who cannot struggle. Two deaths due to plastic bag asphyxia are presented. Both the autopsies were performed at the University Hospital Mortuary, Kuala Lumpur. Both victims were 50-year old married Chinese males. One death was diagnosed as suicide and the other as sexual asphyxia. Sexual asphyxia is generally believed to be a problem associated exclusively with the West. Specific autopsy findings are often absent in deaths due to plastic bag asphyxia and therefore such deaths could be missed when some interested parties have altered the scene and most importantly have removed the plastic bag. A visit to the scene of death is invariably useful.

    Leprosy is a chronic infectious disease and is still a public health problem in Malaysia. In 1926, the Leper Enactment Act was established which required compulsory notification and isolation of leprosy patients. As a result, the National Leprosy Control Centre (NLCC) was built in Sungai Buloh, Selangor. In 1969, the National Leprosy Control programme was launched with the objective of early case finding and decentralisation of treatment of leprosy. The treatment of leprosy patients is integrated with basic Medical and Health services in Malaysia. With the implementation of multiple drug therapy in 1985, the National prevalence rate of leprosy has reduced from 5.7 per 10,000 in 1983 to 1.7 per 10,000 in 1992. The Research Unit in NLCC was established in 1950, where cultivation of Mycobacterium leprae using mouse foot-pad technique is done. This technique is used for assessment of efficacy of chemotherapeutic agents in leprosy. Research activites are also done in collaboration with the Institute for Medical Research in Kuala Lumpur such as isolation of Mycobacterium leprae antigen using T cell clones and phenolic glycolipid antigen.

  20. Geotechnical aspects of development over reclaimed former alluvial mining land and ponds in Malaysia

    Mining of tin placers in Quaternary alluvium is the main type of mining activity in Peninsular Malaysia over the past hundred years. Worked out mines have left behind a landscape consisting of highly inhomogeneous tailing fill and numerous large and medium size ponds often underlain by thick slurries of fine clay and silt on limestone bedrock. Rapid urbanization around the two main tin mining areas in Malaysia, Kuala Lumpur and Ipoh, has led to the use of this previously mined land for residential, commercial and industrial purposes. Highly irregular karstic limestone bedrock poses major problems for the construction of high-rise buildings requiring piling to bedrock. Soft slime trapped during tailing deposition or during reclamation has caused numerous and often irreparable damage to houses built on former mining land. Characterization studies were undertaken on two ponds for their chemical, physical, mineralogical and engineering properties with the aim of finding a solution to the reclamation of slime filled mine ponds. Environmental considerations favour the slime material to be used as foundation material or as raw material for ceramic or bricks. Increase of the solid content by dewatering constitutes the best option to increase the strength of the slime material so as to make it acceptable as foundation material after further treatment. Studies indicate that a few reagents can be used to successfully dewater the slime. Development of a reclamation technique along this line is being carried out.

    The distributions of flies are not only confined to ground level but can also be at higher altitudes. Here, we report three forensic cases involving dipterans in high-rise buildings in Kuala Lumpur, Malaysia. Case 1 involved a corpse of adult female found at the top floor of a fifteen-story apartment. Case 2 dealt with a body of a 75-year-old female discovered in a bedroom on the eleventh floor of an eighteen-story building, while Case 3 was a 52-year-old male found in his fifth floor shop house. Interestingly, entomological analysis revealed that all corpses were infested with similar Dipterans: Megaselia scalaris (Loew) (Diptera: Phoridae), Synthesiomyia nudiseta (Wulp) (Diptera: Muscidae) and sarcophagid (Diptera: Sarcophagidae). The first two species were commonly associated with corpses found indoors at ground level. We noted the additional occurrence of blowflies Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) and Chrysomya rufifacies Macquart (Diptera: Calliphoridae) larvae in Case 2 and Case 3, respectively. Findings from this study are significant as they demonstrate that certain groups of fly can locate dead bodies even in high-rise buildings. Forensic entomofauna research on corpses found at high elevation is scarce and our study has highlighted the peculiarity of the fly species involved in Malaysia.

    126 Malay children from higher income families were followed-up regularly from birth to six years of age in the University Hospital, Kuala Lumpur. Their developmental performance was compared to that of Denver children. Generally, Malaysian and Denver children appear to be similar in their development during the first six years of life except for some minor differences in the personal-social, language and gross motor sectors. Malaysians appear to be slower in self-care but more advanced in "helping around the house", "playing interactive games" and in "separating from mother". They were slightly slower in gross motor function during the first year of life but more advanced during the second year of life. However, they were slightly more advanced in language development. The differences in development between the two groups of children are discussed and it is concluded that the differences can partly be explained by differences in socio-economic or cultural differences between the two groups of children. However, the influence of genetic factors cannot be dismissed.

    INTRODUCTION Family presence (FP) during resuscitation is an increasingly favoured trend, as it affords many benefits to the critically ill patient’s family members. However, a previously conducted study showed that only 15.8% of surveyed Malaysian healthcare staff supported FP during resuscitation. METHODS This cross-sectional study used a bilingual self-administered questionnaire to examine the attitudes and perceptions of the general Malaysian public toward the presence of family members during resuscitation of their loved ones. The questionnaires were randomly distributed to Malaysians in three different states and in the federal territory of Kuala Lumpur. RESULTS Out of a total of 190 survey forms distributed, 184 responses were included for analysis. Of the 184 respondents, 140 (76.1%) indicated that they favoured FP during resuscitation. The most common reason cited was that FP during resuscitation provides family members with the assurance that everything possible had been done for their loved ones (n = 157, 85.3%). Respondents who had terminal illnesses were more likely to favour FP during resuscitation than those who did not, and this was statistically significant (95.0% vs. 73.8%; p = 0.04). CONCLUSION FP during resuscitation was favoured by a higher percentage of the general Malaysian public as compared to Malaysian healthcare staff. This could be due to differences in concerns regarding the resuscitation process between members of the public and healthcare staff. PMID:25189307

    This study aimed to investigate the chemical composition and potential sources of PM10 as well as assess the potential health hazards it posed to school children. PM10 samples were taken from classrooms at a school in Kuala Lumpur's city centre (S1) and one in the suburban city of Putrajaya (S2) over a period of eight hours using a low volume sampler (LVS). The composition of the major ions and trace metals in PM10 were then analysed using ion chromatography (IC) and inductively coupled plasma-mass spectrometry (ICP-MS), respectively. The results showed that the average PM10 concentration inside the classroom at the city centre school (82µg/m(3)) was higher than that from the suburban school (77µg/m(3)). Principal component analysis-absolute principal component scores (PCA-APCS) revealed that road dust was the major source of indoor PM10 at both school in the city centre (36%) and the suburban location (55%). The total hazard quotient (HQ) calculated, based on the formula suggested by the United States Environmental Protection Agency (USEPA), was found to be slightly higher than the acceptable level of 1, indicating that inhalation exposure to particle-bound non-carcinogenic metals of PM10, particularly Cr exposure by children and adults occupying the school environment, was far from negligible.

    A retrospective study was conducted to investigate whether there was a correlation between the histological pattern of renal amyloidosis, the chemical type of amyloid protein involved and the clinical presentation. Eighteen consecutive cases of systemic amyloidosis that had renal biopsies processed and examined histopathologically at the Department of Pathology, Faculty of Medicine, University of Malaya, Kuala Lumpur were reviewed. The age range of patients was 25 to 64 yrs (mean, 46 yrs). The male:female ratio was 2.6:1. Three patients were Malay, 9 Chinese, 3 Indian, 1 Indonesian, 1 Iban, and 1 Bisaya. According to the predominant site of amyloid deposition, 14 cases showed a glomerular pattern and 4 a vascular pattern. 8 cases were designated as 2 anti-human amyloid-A (AA) amyloidosis on the basis of permanganate-sensitivity and immunoreactivity of deposits with anti-human AA protein antibody. Ten cases contained deposits that were permanganate-resistant and nonimmunoreactive for AA protein and were designated as AL in type. The histomorphologic pattern of renal amyloidosis did not provide a reliable means of differentiating AA from AL amyloidosis. The glomerular pattern tended to present with renal manifestations such as nephrotic syndrome and chronic renal failure, whereas the vascular pattern tended to present with nonrenal manifestations such as diarrhoea. These findings may have a bearing on the pathophysiology of amyloidosis and provide clues to appropriate management. PMID:9224755

    This paper presents the mechanical function and characterization of an artificial lightweight geopolymer aggregate (ALGA) using LUSI (Sidoarjo mud) and alkaline activator as source materials. LUSI stands for LU-Lumpur and SI-Sidoarjo, meaning mud from Sidoarjo which erupted near the Banjarpanji-1 exploration well in Sidoarjo, East Java, Indonesia on 27 May 2006. The effect of NaOH molarity, LUSI mud/Alkaline activator (LM/AA) ratio, and Na2SiO3/NaOH ratio to the ALGA are investigated at a sintering temperature of 950 °C. The results show that the optimum NaOH molarity found in this study is 12 M due to the highest strength (lowest AIV value) of 15.79% with lower water absorption and specific gravity. The optimum LUSI mud/Alkaline activator (LM/AA) ratio of 1.7 and the Na2SiO3/NaOH ratio of 0.4 gives the highest strength with AIV value of 15.42% with specific gravity of 1.10 g/cm3 and water absorption of 4.7%. The major synthesized crystalline phases were identified as sodalite, quartz and albite. Scanning Electron Microscope (SEM) image showed more complete geopolymer matrix which contributes to highest strength of ALGA produced. PMID:26006238

    This study investigates the applicability of multivariate statistical techniques including cluster analysis (CA), discriminant analysis (DA), and factor analysis (FA) for the assessment of seasonal variations in the surface water quality of tropical pastures. The study was carried out in the TPU catchment, Kuala Lumpur, Malaysia. The dataset consisted of 1-year monitoring of 14 parameters at six sampling sites. The CA yielded two groups of similarity between the sampling sites, i.e., less polluted (LP) and moderately polluted (MP) at temporal scale. Fecal coliform (FC), NO3, DO, and pH were significantly related to the stream grouping in the dry season, whereas NH3, BOD, Escherichia coli, and FC were significantly related to the stream grouping in the rainy season. The best predictors for distinguishing clusters in temporal scale were FC, NH3, and E. coli, respectively. FC, E. coli, and BOD with strong positive loadings were introduced as the first varifactors in the dry season which indicates the biological source of variability. EC with a strong positive loading and DO with a strong negative loading were introduced as the first varifactors in the rainy season, which represents the physiochemical source of variability. Multivariate statistical techniques were effective analytical techniques for classification and processing of large datasets of water quality and the identification of major sources of water pollution in tropical pastures.

    Fatal acute methamphetamine (MA) poisoning in cases of internal drug trafficking is rarely described in the literature. This case study reports an MA 'body packer' who died from fatal methamphetamine intoxication due to leaking drug packages in the alimentary tract. The deceased was examined by postmortem computed tomography (PMCT), and the results were correlated to subsequent autopsy and toxicological findings. The deceased was arrested by the police when he was found disoriented in the city of Kuala Lumpur. He was transferred to the emergency department on suspicion of drug abuse. The initial drug screening was reactive for amphetamines. Shortly after admission to the hospital, he died despite rigorous resuscitation attempts. The postmortem plain chest and abdominal radiographs revealed multiple suspicious opacities in the gastrointestinal tract attributable to body packages. An unenhanced whole body PMCT revealed twenty-five drug packages, twenty-four in the stomach and one in the transverse colon. At least two were disintegrating, and therefore leaking. The autopsy findings were consistent with the PMCT results. Toxicology confirmed the diagnosis of fatal methamphetamine intoxication. PMID:23404531

    This paper describes a case note and interview study of a cross sectional sample comprised of all children seen and confirmed as being sexually abused between June 1985 and December 1990 by the Suspected Child Abuse and Neglect (SCAN) Team of Kuala Lumpur General Hospital. A total of 101 cases, which represented 18.2% of all child abuse cases, were seen together with their accompanying adults. Information about ethnicity, socioeconomic status, family constellation relationship of perpetrator to the child, and reported psychosocial factors that could have contributed towards the abuse were recorded. The Indian ethnicity group was found to be overrepresented. The mean age of children was 6-8 years, SD 4.1, with age ranging 1.5-16 years. Forty-one and one-half percent were in the age range 5-9 years. Among the important associated psychosocial factors found were the absence of another adult at home, unemployment, and history of drug abuse among the perpetrators. PMID:7583735

    Given the magnitude of drug addiction in Malaysia, the government has given top priority to this issue. It is timely that an assessment of knowledge, attitudes and perceptions related to drug abuse and drug dependents among the general public be carried out. Thus, a nationwide survey was undertaken. A representative sample of 2,591 respondents aged 13 years and above from households were surveyed throughout the 11 states and the Federal Territory of Kuala Lumpur in Peninsula Malaysia. The results revealed that the respondents are moderately knowledgeable on drug abuse, especially information pertaining to treatment, rehabilitation and aftercare services, including education to families against drug abuse. The public possess a negative attitude towards drug dependents. Majority felt that drug addicts do not have the will power to rid themselves of drugs and they also lack a supportive family network system. Many believe that the most vulnerable group are the adolescents. Respondents were aware of the type of drugs commonly abused, although they failed to realise their long-term effects. Respondents do not attribute low education, large family and marginal income to the background of drug dependents. The findings showed gaps and misconceptions in terms of knowledge, attitudes and perceptions of the public. Accurate knowledge on, and right attitudes and perceptions towards drug related issues would certainly benefit the public in timely prevention of drug abuse. PMID:9037810

    Prospects for a stable, prospering economy in Malaysia appear threatened by an uneven distribution of wealth among non-Malay, particularly Chinese, residents. Native Malays, Bumiputra, have benefitted from the government's 20 year New Economic Policy, a system of subsidies to correct economic imbalances among the races. Malay corporate ownership has increased from 2.4% in 1970 to 28% in 1979. However, equity must increase by 26% annually to meet NEP targets. Without the GNP expanding 7-8% yearly, the government will be tempted to acquire assets at low prices. 70% of the total Malay ownership was held by public enterprises holding equity in trust. An elite group of Bumiputra will own a fair number of shares reserved by 1970. 1/5 of the population of Kuala Lumpur are squatters. Among these groups, communal tension is high. The Chinese businessmen are most resistant to native management. Since they control private domestic investment, they have political power. The Industrial Coordination Act (ICA), which gives power to civil servants through a licensing system, protects the system. The Asian Foundation supports management training, business development, and university demonstration projects in legal aid, solar energy, and community psychiatry. Malaysian competence in English enables widespread distribution of the Books for Asia program. PMID:12335915

    Objectives The objectives are to assess the prevalence and determinants of cardiovascular disease (CVD) risk factors among the residents of Community Housing Projects in metropolitan Kuala Lumpur, Malaysia. Method By using simple random sampling, we selected and surveyed 833 households which comprised of 3,722 individuals. Out of the 2,360 adults, 50.5% participated in blood sampling and anthropometric measurement sessions. Uni and bivariate data analysis and multivariate binary logistic regression were applied to identify demographic and socioeconomic determinants of the existence of having at least one CVD risk factor. Results As a Result, while obesity (54.8%), hypercholesterolemia (51.5%), and hypertension (39.3%) were the most common CVD risk factors among the low-income respondents, smoking (16.3%), diabetes mellitus (7.8%) and alcohol consumption (1.4%) were the least prevalent. Finally, the results from the multivariate binary logistic model illustrated that compared to the Malays, the Indians were 41% less likely to have at least one of the CVD risk factors (OR = 0.59; 95% CI: 0.37 - 0.93). Conclusion In Conclusion, the low-income individuals were at higher risk of developing CVDs. Prospective policies addressing preventive actions and increased awareness focusing on low-income communities are highly recommended and to consider age, gender, ethnic backgrounds, and occupation classes.

    Objectives: The aim of this research was to examine the average glandular dose (AGD) of radiation among different breast compositions of glandular and adipose tissue with auto-modes of exposure factor selection in digital breast tomosynthesis. Methods: This experimental study was carried out in the National Cancer Society, Kuala Lumpur, Malaysia, between February 2012 and February 2013 using a tomosynthesis digital mammography X-ray machine. The entrance surface air kerma and the half-value layer were determined using a 100H thermoluminescent dosimeter on 50% glandular and 50% adipose tissue (50/50) and 20% glandular and 80% adipose tissue (20/80) commercially available breast phantoms (Computerized Imaging Reference Systems, Inc., Norfolk, Virginia, USA) with auto-time, auto-filter and auto-kilovolt modes. Results: The lowest AGD for the 20/80 phantom with auto-time was 2.28 milliGray (mGy) for two dimension (2D) and 2.48 mGy for three dimensional (3D) images. The lowest AGD for the 50/50 phantom with auto-time was 0.97 mGy for 2D and 1.0 mGy for 3D. Conclusion: The AGD values for both phantoms were lower against a high kilovolt peak and the use of auto-filter mode was more practical for quick acquisition while limiting the probability of operator error.

    The purpose of this study was to investigate attitudes toward infant feeding among women in their 3rd trimester of pregnancy. A total of 74 primiparous and multiparous mothers ranging in age from 18-45 who were attending antenatal clinics near Kuala Lumpur were interviewed, 78.3% of which were Malay, 12.2% Chinese, and 9.5% Indian. Most were from middle class families, and only 6.5% had never attended school. Although 91.9% considered breastmilk as being the best food for babies, only 63.5% preferred to breastfeed; 8.1% chose powdered milk and 28.4% chose mixed feeding. Most of those who chose not to breastfeed were Chinese, working women, and/or women from higher income groups. Information on the intended duration of breastfeeding showed that multiparous women and working women did not intend to breastfeed for more than 6 months. Most women did not believe that either breast milk or powdered milk alone was sufficient for infants up to 5 months of age, and intended to supplement with solid food before that age. Since 93.2% of the respondents had already decided on feeding methods by their last trimester, it is important that nutritional information be given during this time.

    The survey of Thysanoptera in peninsular Malaysia has been concentrated largely in areas growing crops and flowers around Kuala Lumpur, and the Cameron Highlands, and there are few records of these insects from native forests particularly in the northern part of the country. The two species described here were collected during a recent visit to Belum-Temengor Forest Complex, in Perak State, part of the second largest forested area on the peninsular, and connected to the Bang Lang National Park, in Yala Province, Thailand. This forest has been well known as home to a number of endangered animals, including Malayan tigers and Asian elephants, as well as remarkable plant species such as Rafflesia with the world's largest flowers (Abdullah et al. 2011). Despite this, forest areas are facing a major challenge from the insatiable demand for timber, palm oil and minerals, with an 80% increase in deforestation rate in Malaysia between 1990 and 2005 (FAO 2010). Forested land in peninsular Malaysia has been estimated at 5.88 million-ha or 44% of total area, but the coverage of reserved virgin forest is about 0.40 % or 23,002-ha (Dahlan 2008).

    Objective While living overseas in another culture, retirees need to adapt to a new environment but often this causes difficulties, particularly among those elderly who require healthcare services. This study examines factors affecting healthcare service utilisation among Japanese retirees in Malaysia. Design We conducted 6 focus group discussions with Japanese retirees and interviewed 8 relevant medical services providers in-depth. Guided by the Andersen Healthcare Utilisation Model, we managed and analysed the data, using QSR NVivo 10 software and the directed content analysis method. Setting We interviewed participants at Japan Clubs and their offices. Participants 30 Japanese retirees who live in Kuala Lumpur and Ipoh, and 8 medical services providers. Results We identified health beliefs, medical symptoms and health insurance as the 3 most important themes, respectively, representing the 3 dimensions within the Andersen Healthcare Utilisation Model. Additionally, language barriers, voluntary health repatriation to Japan and psychological support were unique themes that influence healthcare service utilisation among Japanese retirees. Conclusions The healthcare service utilisation among Japanese retirees in Malaysia could be partially explained by the Andersen Healthcare Utilisation Model, together with some factors that were unique findings to this study. Healthcare service utilisation among Japanese retirees in Malaysia could be improved by alleviating negative health beliefs through awareness programmes for Japanese retirees about the healthcare systems and cultural aspects of medical care in Malaysia.

    The Malaysian state of Penang consists of the Island of Penang and the adjacent mainland Province Wellesley. Its total area is 1044 square kilometers and its total population is 776,000. The island population is 65% Chinese and 21% Malay; the mainland population is 44.5% Chinese and 43% Malay. Although Penang, like Malaysia as a whole, has suffered violent racial conflict between the Malays and the Chinese in the past, the future for the whole of the nation, including Penang, seems promising. Some racial inequality, however, continues to exist. The main industries of Penang are fishing (now in a depressed state through overexploitation of the fisheries), electronics manufacture, and tourism, which has not been deterred by some degree of environmental pollution. Relations between Georgetown, the state capital, and Kuala Lumpur are generally good, although there is routine rivalry for national development funds, and Penang's Chief Minister frequently prefers to look to Singapore for his inspiration as well as his practical guidance in undertaking programs relating to public housing, industrialization, and social welfare. At the same time Penang represents an alluring place for Singaporean investment.

    Changes in living standards, tastes, views and education has changed the lifestyles where people are more emphasizing on quality and satisfaction with public amenities provided. One of the services provided is the KL Monorail; a public transport service which is based on a single beam track in the city that connects the north and center of Kuala Lumpur. Therefore, this study measures the customer satisfaction on the KL Monorail services and to identify the factors that should be given priority in improving their service levels. There were seven attributes being studied, namely the informations, the situation at the station, the situation in the KL Monorail, customer service, safety, efficiency and other aspects. The analysis found that the overall customer satisfactionis mean is 4.86. Based on the measurement of Penalty-Reward Contrast Analysis (PRCA), most of the KL Monorail service attribute are at moderate level of satisfaction except for the attributes at the station that have lower level of satisfaction. Therefore, a remedial actions or planning is needed to improve the customer satisfaction on the KL Monorail services.

    A Streptomyces strain, MUM256 was isolated from Tanjung Lumpur mangrove soil in Malaysia. Characterization of the strain showed that it has properties consistent with those of the members of the genus Streptomyces. In order to explore the potential bioactivities, extract of the fermented broth culture of MUM256 was prepared with organic solvent extraction method. DPPH and SOD activity were utilized to examine the antioxidant capacity and the results have revealed the potency of MUM256 in superoxide anion scavenging activity in dose-dependent manner. The cytotoxicity of MUM256 extract was determined using cell viability assay against 8 different panels of human cancer cell lines. Among all the tested cancer cells, HCT116 was the most sensitive toward the extract treatment. At the highest concentration of tested extract, the result showed 2.3-, 2.0-, and 1.8-folds higher inhibitory effect against HCT116, HT29, and Caco-2 respectively when compared to normal cell line. This result has demonstrated that MUM256 extract was selectively cytotoxic toward colon cancer cell lines. In order to determine the constituents responsible for its bioactivities, the extract was then subjected to chemical analysis using GC-MS. The analysis resulted in the identification of chemical constituents including phenolic and pyrrolopyrazine compounds which may responsible for antioxidant and anticancer activities observed. Based on the findings of this study, the presence of bioactive constituents in MUM256 extract could be a potential source for the development of antioxidative and chemopreventive agents.

    Chronic obstructive pulmonary disease (COPD) is a systemic disease that leads to weight loss and muscle dysfunction resulting in an increase in mortality. This study aimed to determine the prevalence rate of malnutrition and nutritional status and also factors associated with nutritional status. A total of 149 subjects were involved in the cross-sectional study. The study was conducted at two medical centers in Kuala Lumpur, Malaysia. The results of the study showed that malnutrition was more prevalent (52.4%) in the subjects with severe stages of COPD as compared to mild and moderate COPD stages (26.2%) (P < 0.05). Fat-free mass depletion as assessed using fat-free mass index (FFMI) affected 41.9% of the subjects. Plasma vitamin A, peak expiratory flow (PEF), and handgrip were the predictors for body mass index (BMI) (R(2) = 0.190, P < 0.001). Plasma vitamin A and force expiratory volume in one second (FEV(1)) were the predictors of FFMI (R(2) = 0.082, P = 0.007). BMI was the predictor of respiratory factors, that is, FEV(1)% predicted (R(2) = 0.052, P = 0.011). It can be concluded that there is a need to identify malnourished COPD patients for an appropriate nutrition intervention. PMID:23209935

    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 centers, 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 and 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. PMID:25999867

    Transboundary haze episodes caused by seasonal forest fires have become a recurrent phenomenon in Southeast Asia, with serious environmental, economic, and public health implications. Here we present a cross-sectional survey conducted among people in Kuala Lumpur and surrounds to assess the links between knowledge, attitudes, and practices in relation to the transboundary haze episodes. Of 305 respondents, 125 were amateur athletes participating in a duathlon event and the remainder were surveyed in an inner-city shopping mall. Across the whole sample, people who possessed more factual information about the haze phenomenon showed significantly higher levels of concern. Duathletes were more knowledgeable than non-duathletes and also more concerned about the negative effects of haze, especially on health. For all people who regularly practice outdoor sports (including people interviewed at the shopping mall), higher levels of knowledge and concerned attitudes translated into a greater likelihood of engaging in protective practices, such as cancelling their outdoor training sessions, while those with greater knowledge were more likely to check the relevant air pollution index on a daily basis. Our results indicate that the provision of accurate and timely information about air quality to residents will translate into beneficial practices, at least among particularly exposed individuals, such as amateur athletes who regularly practice outdoor sports.

    This study involves the adoption of the Geographic Information System (GIS) modeling approach to determine the quickest routes for fresh vegetable delivery. During transport, fresh vegetables mainly deteriorate on account of temperature and delivery time. Nonetheless, little attention has been directed to transportation issues in most areas within Kuala Lumpur. In addition, perishable food normally has a short shelf life, thus timely delivery significantly affects delivery costs. Therefore, selecting efficient routes would consequently reduce the total transportation costs. The regression model is applied in this study to determine the parameters that affect route selection with respect to the fastest delivery of fresh vegetables. For the purpose of this research, ArcGIS software with network analyst extension is adopted to solve the problem of complex networks. The final output of this research is a map of quickest routes with the best delivery times based on all variables. The variables tested from regression analysis are the most effective parameters to make the flow of road networks slower. The objective is to improve the delivery services by achieving the least drive time. The main findings of this research are that Land use such as residential area and population as variables are the effective parameters on drive time. PMID:27579003

    This study aimed to investigate the chemical composition and potential sources of PM10 as well as assess the potential health hazards it posed to school children. PM10 samples were taken from classrooms at a school in Kuala Lumpur's city centre (S1) and one in the suburban city of Putrajaya (S2) over a period of eight hours using a low volume sampler (LVS). The composition of the major ions and trace metals in PM10 were then analysed using ion chromatography (IC) and inductively coupled plasma-mass spectrometry (ICP-MS), respectively. The results showed that the average PM10 concentration inside the classroom at the city centre school (82µg/m(3)) was higher than that from the suburban school (77µg/m(3)). Principal component analysis-absolute principal component scores (PCA-APCS) revealed that road dust was the major source of indoor PM10 at both school in the city centre (36%) and the suburban location (55%). The total hazard quotient (HQ) calculated, based on the formula suggested by the United States Environmental Protection Agency (USEPA), was found to be slightly higher than the acceptable level of 1, indicating that inhalation exposure to particle-bound non-carcinogenic metals of PM10, particularly Cr exposure by children and adults occupying the school environment, was far from negligible.

    Abstract. This paper examines the effectiveness of media in public awareness of the HIV/AIDS issue among the public in an area in central Selangor, comprising Kuala Lumpur and its surroundings and suburbs in Malaysia. Cross-sectional survey questionnaires were distributed to 384 respondents about accessing the public awareness of modes of HIV transmission, perceptions and attitudes towards people living with HIV/AIDS, as well as people's understanding about government policies to curb HIV/AIDS. Health care practitioners and newspapers were the preferred sources of information seeking on HIV/AIDS among the public. Most of the respondents were aware of the modes of HIV transmission. However, they were some respondents who still have misconceptions about the modes of transmission. Most of the respondents were not aware about the government's significant policies to address HIV/AIDS in the region. Overall, the respondents had certain knowledge about HIV transmission modes and moderate positive perceptions and attitudes towards people living with HIV/AIDS. Future studies should be conducted to examine about who sets the agenda in the media, and apart from gatekeepers, who are the real decision makers in deciding what is important to inform the public.

    Human metapneumovirus (HMPV) is an important viral respiratory pathogen worldwide. Current knowledge regarding the genetic diversity, seasonality and transmission dynamics of HMPV among adults and children living in tropical climate remains limited. HMPV prevailed at 2.2% (n = 86/3,935) among individuals presented with acute respiratory tract infections in Kuala Lumpur, Malaysia between 2012 and 2014. Seasonal peaks were observed during the northeast monsoon season (November–April) and correlated with higher relative humidity and number of rainy days (P < 0.05). Phylogenetic analysis of the fusion and attachment genes identified the co-circulation of three known HMPV sub-lineages, A2b and B1 (30.2% each, 26/86) and B2 (20.9%, 18/86), with genotype shift from sub-lineage B1 to A2b observed in 2013. Interestingly, a previously unrecognized sub-lineage of A2 was identified in 18.6% (16/86) of the population. Using a custom script for network construction based on the TN93 pairwise genetic distance, we identified up to nine HMPV transmission clusters circulating as multiple sub-epidemics. Although no apparent major outbreak was observed, the increased frequency of transmission clusters (dyads) during seasonal peaks suggests the potential roles of transmission clusters in driving the spread of HMPV. Our findings provide essential information for therapeutic research, prevention strategies, and disease outbreak monitoring of HMPV. PMID:27279080

    Three cases of neonatal chylous ascites (CCA) were managed in the neonatal unit, University Hospital, Kuala Lumpur, over the past 9 years. Fetal ascites and polyhydramnios were the sole abnormalities detected in all three babies by antenatal ultrasonography. They were born at 36 weeks' gestation and their birth weights ranged from 3.0 kg to 3.8 kg. All three infants had abdominal distension at birth. Milky ascitic fluid was obtained after starting enteral feedings. Analysis of the ascitic fluid revealed a raised white blood cell count (predominantly lymphocytic) and triglycerides (1.4 - 3.8 mmol/l), cholesterol (1.6 - 2.8 mmol/l), and protein levels (25 - 41 g/l). Conservative management with skimmed milk and medium-chain triglycerides in one infant and Pregestimil in another was instituted. these two infants with CCA were clinically normal when reviewed at 19 months and 3.5 years of age. The third infant had a gut malrotation and associated pyloric septum; he died from complications of a laparotomy. The literature on this rare condition is reviewed.

    This study was conducted to determine the SWCC of unsaturated tropical residual soil in Kuala Lumpur, Malaysia. Undisturbed soil samples at five locations of high-risk slopes area were taken at a depth of 0.5 m using block sampler. In the determination of the SWCC, the pressure plate extractor with the capacity of 1500 kN/m2 has been used. The index properties of the soil such as natural moisture content, Atterberg limits, specific gravity, and soil classification are performed according to BS 1377: Part 2: 1990. The results of index properties show that the natural moisture content of the soil is between 36% to 46%, the plasticity index is between 10% - 26%, the specific gravity is between 2.51 - 2.61 and the soils is classified as silty organic clay of low plasticity. The SWCC data from the pressure plate extractor have been fitted with the Fredlund and Xing equation. The results show that the air entry value and residual matric suction for residual soils are in the range of 17 kN/m2 to 24 kN/m2 and 145 kN/m2 to 225 kN/m2 respectively. From the fitting curve, it is found that the average value of the Fredlund and Xing parameters such as a, n and m are in the range of 0.24-0.299, 1.7-4.8 and 0.142-0.440 respectively.

    Landslide is one of prominent geohazards that continuously affecting the tropical countries including Malaysia. Frequent occurrences of landslides at hillslopes during the heavy rainy periods have resulted in public fear for the safety of their life and properties. For the past 25 years, many landslides have occurrences have been reported in Klang Valley especially at the hilly terrain residential areas. A landslide monitoring scheme is therefore very crucial and should be carried out continuously. Various studies have been conducted to monitor landslide activities such as conventional geotechnical and geodetic techniques. Each of these techniques has its own advantages and limitations. Therefore, this study focuses on the effectiveness of the combination approach of GPS technology and inclinometer techniques for landslide monitoring. The study area is located at residential area Section 5, Wangsa Maju, Kuala Lumpur, Malaysia. The inclinometer instrument has been placed at five (5) selected monitoring points and three (3) epochs of inclinometer measurements were made. At the same time, the GPS observations have also been carried out for three (3) epochs separately using GPS static techniques. This GPS network consists of four (4) control points and eleven (11) monitoring points. The GPS observations data were validated, processed and adjusted using two (2) adjustment software namely Trimble Geomatic Office (TGO) version 1.6, and GPS Adjustment and Deformation Analysis (GADA). The results have shown that the GPS technique can be implemented with inclinometer technique to detect horizontal displacements up to +/- 30 mm and vertical displacements less than +/- 50 mm.

    The uptake of naturally occurring thorium, radium and potassium by sawi (Japanese Mustard) from disused tin mining was studied. Both soil and sawi sample were collected from a vegetable farm located 15 km from Kuala Lumpur, Malaysia where the farm has been operating for 22 years on a disused tin mining. By using a gamma spectroscopy system, the transfers of radionuclides from soil to plants were investigated. The highest values of radionuclides in the soil was K-40 which is 52.8 Bq kg{sup -1} and the lowest was Ra-226 which is 6.51 Bq kg{sup -1}. The activity of Th-232 is 18.5 Bq kg{sup -1}. The activity of radionuclides in the sawi sample shows higher values as compared to the soil sample. The highest values of radionuclides in the sawi were K-40 which is 446 Bq kg{sup -1} and the lowest was Ra-226 which is 17.5 Bq kg{sup -1}. The activity of Th-232 is 65.2 Bq kg{sup -1}. The concentration of radionuclides in soils and plants can be used for the determination of soil-to-plant transfer factors. The soil to plant transfer factors (TF) were calculated and observed to be 2.68 for radium-226, 3.52 for thorium-232 and the highest which is 3.97 for potassium-40.

    Bartonella elizabethae has been known to cause endocarditis and neuroretinitis in humans. The genomic features and virulence profiles of a B. elizabethae strain (designated as BeUM) isolated from the spleen of a wild rat in Kuala Lumpur, Malaysia are described in this study. The BeUM strain has a genome size of 1,932,479bp and GC content of 38.3%. There is a high degree of conservation between the genomes of strain BeUM with B. elizabethae type strains (ATCC 49927 and F9251) and a rat-borne strain, Re6043vi. Of 2137 gene clusters identified from B. elizabethae strains, 2064 (96.6%) are indicated as the core gene clusters. Comparative genome analysis of B. elizabethae strains reveals virulence genes which are known in other pathogenic Bartonella species, including VirB2-11, vbhB2-B11, VirD4, trw, vapA2-5, hbpA-E, bepA-F, bepH, badA/vomp/brp, ialB, omp43/89 and korA-B. A putative intact prophage has been identified in the strain BeUM, in addition to a 8kb pathogenicity island. The whole genome analysis supports the zoonotic potential of the rodent-borne B. elizabethae, and provides basis for future functional and pathogenicity studies of B. elizabethae.

    Numerous studies are demonstrating that engaging undergraduate students in original research can improve their achievement in the science, technology, engineering, and mathematics (STEM) fields and increase the likelihood that some of them will decide to pursue careers in these disciplines. Associated with this increased prominence of research in the undergraduate curriculum are greater expectations from funders, colleges, and universities that faculty mentors will help those students, along with their graduate students and postdoctoral fellows, develop an understanding and sense of personal and collective obligation for responsible conduct of science (RCS). This Feature describes an ongoing National Research Council (NRC) project and a recent report about educating faculty members in culturally diverse settings (Middle East/North Africa and Asia) to employ active-learning strategies to engage their students and colleagues deeply in issues related to RCS. The NRC report describes the first phase of this project, which took place in Aqaba and Amman, Jordan, in September 2012 and April 2013, respectively. Here we highlight the findings from that report and our subsequent experience with a similar interactive institute in Kuala Lumpur, Malaysia. Our work provides insights and perspectives for faculty members in the United States as they engage undergraduate and graduate students, as well as postdoctoral fellows, to help them better understand the intricacies of and connections among various components of RCS. Further, our experiences can provide insights for those who may wish to establish "train-the-trainer" programs at their home institutions. PMID:24297287

    Islamic clerics, scholars, activists, and other authorities in Malaysia decided to lay in education for everyone as a solution to the AIDS epidemic in their country. In addition, they called on the community to be caring towards sufferers, which they believe is the way of Islam. This resolution was agreed upon during a meeting wherein religious officials recognized their role in AIDS prevention by equipping people with spiritual values and teaching everyone compassion. The resolution, however, has challenged the orthodoxy in some Islamic circles where AIDS is regarded as a "manifestation of God's punishment" which has consequently scared off many Muslim sufferers from approaching religious bodies. Religious advisers also admits that their call for full information about prevention, from urging abstinence and marital fidelity to promoting the use of condoms, still needs to be supported by individual state authorities. Among the AIDS council's future plans are to set up an information booth at a Kuala Lumpur mosque and to raise awareness in state religious departments through a booklet entitled AIDS Education Through Imams.

    Index tracking is a popular form of passive fund management in stock market. Passive management is a buy-and-hold strategy that aims to achieve rate of return similar to the market return. Index tracking problem is a problem of reproducing the performance of a stock market index, without purchasing all of the stocks that make up the index. This can be done by establishing an optimal portfolio that minimizes risk or tracking error. An improved index tracking (enhanced index tracking) is a dual-objective optimization problem, a trade-off between maximizing the mean return and minimizing the tracking error. Enhanced index tracking aims to generate excess return over the return achieved by the index. The objective of this study is to compare the portfolio compositions and performances by using two different approaches in enhanced index tracking problem, which are goal programming and cointegration. The result of this study shows that the optimal portfolios for both approaches are able to outperform the Malaysia market index which is Kuala Lumpur Composite Index. Both approaches give different optimal portfolio compositions. Besides, the cointegration approach outperforms the goal programming approach because the cointegration approach gives higher mean return and lower risk or tracking error. Therefore, the cointegration approach is more appropriate for the investors in Malaysia.

    Enhanced index tracking is a popular form of passive fund management in stock market. Enhanced index tracking aims to generate excess return over the return achieved by the market index without purchasing all of the stocks that make up the index. This can be done by establishing an optimal portfolio to maximize the mean return and minimize the risk. The objective of this paper is to determine the portfolio composition and performance using goal programming approach in enhanced index tracking and comparing it to the market index. Goal programming is a branch of multi-objective optimization which can handle decision problems that involve two different goals in enhanced index tracking, a trade-off between maximizing the mean return and minimizing the risk. The results of this study show that the optimal portfolio with goal programming approach is able to outperform the Malaysia market index which is FTSE Bursa Malaysia Kuala Lumpur Composite Index because of higher mean return and lower risk without purchasing all the stocks in the market index.

    Banking system plays an important role in the economic development of any country. Domestic banks, which are the main components of the banking system, have to be efficient; otherwise, they may create obstacle in the process of development in any economy. This study examines the technical efficiency of the Malaysian domestic banks listed in the Kuala Lumpur Stock Exchange (KLSE) market over the period 2005-2010. A parametric approach, Stochastic Frontier Approach (SFA), is used in this analysis. The findings show that Malaysian domestic banks have exhibited an average overall efficiency of 94 percent, implying that sample banks have wasted an average of 6 percent of their inputs. Among the banks, RHBCAP is found to be highly efficient with a score of 0.986 and PBBANK is noted to have the lowest efficiency with a score of 0.918. The results also show that the level of efficiency has increased during the period of study, and that the technical efficiency effect has fluctuated considerably over time. PMID:22900009

    A fulminating extension of rabies—which has been enzootic in northern Malaya since 1924—occurred in Kuala Lumpur in April 1952. The outbreak was suppressed by the compulsory mass vaccination of dogs, stringent legislation, and intensive stray-dog destruction. Similar measures are being employed in the current campaign, the aim of which is the complete eradication of the disease. From an average annual incidence of 112 confirmed canine cases prior to 1952—when a total of 198 cases was reported—the incidence fell to 15 cases (all in unvaccinated dogs) for the period January-November 1953, during the last 5½ months of which no case in either animals or man was reported. It is considered that the extensive publicity campaign and strict enforcement of the control measures have contributed measurably to the present improved position. Statistics relating to confirmed cases in dogs previously vaccinated with (a) phenolized 20% brain-tissue suspension vaccine (buffalo origin) and (b) chicken-embryo vaccine (Flury strain) are quoted and their probable significance in favour of the latter under Malayan conditions is discussed. The hypothesis that the development of rabies may, in many instances, have been blocked by the vaccine is advanced. The plan for a pan-Federation compulsory vaccination campaign in 1954, to consolidate the 1952-3 improvements, is outlined. PMID:13182594

    The aim of the study was to determine the incidence of food and house dust mite (HDM) allergy in patients with nasal congestion and rhinorrhea attending the Otorhinolaryngology Clinic, National University of Malaysia, Kuala Lumpur. This was a prospective matched, controlled study of patients skin prick tested with commercial food and common aeroallergens. The participants were 148 Malaysian adults with symptoms of nasal congestion and rhinorrhea and 113 adult Malaysian control subjects without rhinitis symptoms. The skin prick test (SPT) was used to evaluate 11 foods common to the Malaysian diet and 3 HDM inhalants. Forty-eight percent of the patients with rhinitis had positive SPT results to foods, compared with 4.4% of control subjects (P < 0.05). The most commonly implicated foods were shrimp (48%) and rice (30%), which are common in the Malaysian diet. Seventy-two percent of rhinitis patients had positive SPT results to HDM, compared with 22.2% of control subjects (P < 0.05). Patients with rhinitis also had significantly more gastrointestinal problems than control subjects (P < 0.05). The incidences of HDM and food allergy are significantly greater in Malaysian adults with rhinitis symptoms than in control subjects without rhinitis. The effect of avoidance or immunotherapy awaits further study.

    The digital age for cadastral surveying started in stages, more than 20 years ago in Malaysia and JUPEM played a vital role in its successful implementation nationwide. One of the key products of cadastral survey is cadastral maps, which provide useful information for any land information system. However, as technology evolved and simplicity is familiarised, better services are anticipated and have affected how cadastral survey information are perceived. A paradigm shift is necessary where enriched cadastral information is required for multiple usage and allow real cadastral information based services to users. On that note, JUPEM is intrigued to develop a system where National Digital Cadastral Database is value added with other geospatial information for a smart and multipurpose environment and clearly be interpreted as a decision making tool with the aids of 3D realistic spatial data, namely SmartKADASTER. The SmartKADASTER is an ongoing project developed by JUPEM with the aim to establish a realistic and SMART cadastral-based spatial analysis platform for an effective planning, decision making, enabling efficiencies and enhancing communication and management to support SMART services towards SMART City enablement in Malaysia. It is developed in phases with the Federal Territory of Putrajaya and Kuala Lumpur as the initial project implementation area. This paper provides awareness and insights of the on-going development of the project and how it could benefit potential users and stakeholders.

    This study seeks to measure religiosity in an Islamic context and to assess its effects on the personal well-being of Muslims. The determinants of religiosity included under this research are prayer, beliefs, and worship. This research also attempts to examine the coping strategies Muslims use to deal with life problems and changes such as prayer, supplication, trust and reliance on God, remembrance of death, and concept of life after death. Today, many scales of religiosity are being put into use among Muslims. This study measures religiosity and its effects on the well-being of Muslim academicians. The researchers used 315 Muslim female of academic staff as respondents, working in Research Universities in the Klang Valley such as University of Malaya, National University and Putra University area of Kuala Lumpur, Malaysia. Their ages ranged from 30 to 60 years. The results of this study show that there exists a positive yet significant correlation between personal well-being and religiosity. The well-being also shows significant positive correlations with beliefs and worship and prayer.

Materials and methods Eighty‐six patients with COPD were enrolled into a prospective, observational study at the respiratory outpatient clinic, National University Hospital Malaysia (Hospital Universiti Kebangsaan Malaysia ‐ HUKM), Kuala Lumpur. Results Our study found modest correlation between the forced expiratory volume in 1 s (FEV1), 6 min walk distance and the SGRQ scores with mean (SD) values of 0.97 (0.56) litres/s, 322 (87) m and 43.7 (23.6)%, respectively. K‐Means cluster analysis identified four distinct clusters which reached statistical significance which was refined to develop a new cumulative staging system. The SAFE Index score correlated with the number of exacerbations in 2 years (r = 0.497, p<0.001). Conclusion We have developed the SGRQ, Air‐Flow limitation and Exercise tolerance Index (SAFE Index) for the stratification of severity in COPD. This index incorporates the SGRQ score, the FEV1 % predicted and the 6 min walk distance. The SAFE Index is moderately correlated with the number of disease exacerbations. PMID:17621621

    This paper examines data on the sexual activities of 1,200 Malaysian adolescents aged 15-21 years based on a probability household sampled survey carried out in Kuala Lumpur in 1986. Sexual behaviours like premarital sexual intercourse, contraceptive usage and masturbation were presented. Of the 1,181 unmarried respondents, 9% (105) reported having had sexual intercourse; males were significantly more experienced compared to females. Older age groups were also found to be more sexually active than the younger ones. Among those who had experience dating (n = 521), 20% (105) have experienced sexual intercourse, 44% (228) have kissed and necked, and 35% (183) have experienced petting, while 24% (130) have had no physical intimacies. Poor use of contraception was also revealed. The most commonly used were condoms, oral contraceptives and withdrawal. With regard to masturbation, males begin this practice relatively earlier than females. Almost half of those who indulged in masturbation were worried by the act, especially the females. Implications of the findings are discussed.

    Fast food restaurants are popular among price-sensitive youths and working adults who value the conducive environment and convenient services. McDonald's chains of restaurants promote their sales during lunch hours by offering package meals which are perceived to be inexpensive. These promotional lunch meals attract good response, resulting in occasional long queues and inconvenient waiting times. A study is conducted to monitor the distribution of waiting time, queue length, customer arrival and departure patterns at a McDonald's restaurant located in Kuala Lumpur. A customer survey is conducted to gauge customers' satisfaction regarding waiting time and queue length. An android app named Que is developed to perform onsite queuing analysis and report key performance indices. The queuing theory in Que is based upon the concept of Poisson distribution. In this paper, Que is utilized to perform queuing analysis at this McDonald's restaurant with the aim of improving customer service, with particular reference to reducing queuing time and shortening queue length. Some results will be presented.

    Streptomyces pluripotens MUSC 137 was isolated from mangrove soil obtained from Tanjung Lumpur, Pahang, Malaysia. We investigated the phylogenetic, genomic, biochemical, and phenotypic characteristics of this strain. Uniquely adapted microorganisms from mangrove habitats have previously yielded compounds of biopharmaceutical interest. In order to examine the bioactivities possessed by the strain, fermentation extract was prepared through solvent extraction method prior to bioactivities screenings. Antioxidant activity was examined via DPPH assay while the cytotoxic effect was assessed by means of examining the activity of the extract against selected human cancer cell lines, namely colon cancer cells (HCT-116, Caco-2, SW480, and HT-29), breast cancer cell (MCF-7), lung cancer cell (A549), prostate cancer cell (DU145), and cervical cancer cell (Ca Ski). The results revealed MUSC 137 possesses significant antioxidant activity and demonstrates cytotoxic effect against several cancer cell lines tested. The results indicated MCF-7 cells were most susceptible to the extract with the lowest IC50 (61.33 ± 17.10 μg/mL), followed by HCT-116 and A549. Additionally, selective index (SI) showed that MUSC 137 extract was less toxic against normal cell lines when compared to MCF-7 and HCT-116 cells. The extract was further subjected to chemical analysis using GC–MS and revealed the presence of deferoxamine and pyrrolizidines related compounds which may account for the antioxidant and cytotoxic properties observed.

    The fast increase in the rate of uptake of smoking amongst adolescent girls in Malaysia is a public health concern. The objective of this study was to investigate factors that influenced the initiation of smoking and the effects of advertisement on consolidating the smoking habit among teenage girls in the urban city of Kuala Lumpur. Qualitative research was conducted using both interviews and focus group discussions with groups of adolescent girls. Data collected was analysed using grounded thematic theory methodology and validated using methodological triangulation. The reasons for initiating smoking elicited from the study can be grouped into 4 general themes; influence by peers, influence of seeing parents smoking, misguided belief that it could alleviate stress and finally that it would impress others. Smoking imageries in media and advertisements were not primary influencing factors in the initiation of smoking but it encouraged them to progress to become regulars. Ways should be sought to empower girls to feel more confident about resisting pressures to initiate smoking. This could be done through activities such as positive peer sports, education on how to alleviate stress and curbing of smoking imageries in the media.

    Background: Police Stress Questionnaire (PSQ) was developed to measure police-specific stressors. The present study was the first to have translated the PSQ to Malay. This study aims to test the reliability, construct validity, and component structure of the Malay-version PSQ. Methods: A set of survey consisted of the Malay-version PSQ, General Health Questionnaire (GHQ-12), Job Content Questionnaire (JCQ), Global Stress Questionnaire (GSQ) and General Self-rated Health (GSRH) were distributed to 300 traffic police officers in Kuala Lumpur and all traffic police officers in a few districts of Pahang and Negeri Sembilan. Results: The response rate was 65.5% (N = 262). The reported Cronbach’s alpha coefficient was 0.93 for Operational PSQ (PSQ-Op) and 0.94 for Organisational PSQ (PSQ-Org). Findings indicated that the PSQ had positive construct validity with the GSRH, GSQ, and GHQ. After excluding four factors related to lifestyles, all police-specific stressors were highly loaded (0.50) in one component. Conclusion: It is confirmed that the Malay-version PSQ, excluding the four factors related to lifestyle, was uni-dimensional, reliable, and a valid questionnaire. This study proffers a potentially better instrument for assessing the stressors among Malaysian police. PMID:25977621

    The purpose of this study was to investigate attitudes toward infant feeding among women in their 3rd trimester of pregnancy. A total of 74 primiparous and multiparous mothers ranging in age from 18-45 who were attending antenatal clinics near Kuala Lumpur were interviewed, 78.3% of which were Malay, 12.2% Chinese, and 9.5% Indian. Most were from middle class families, and only 6.5% had never attended school. Although 91.9% considered breastmilk as being the best food for babies, only 63.5% preferred to breastfeed; 8.1% chose powdered milk and 28.4% chose mixed feeding. Most of those who chose not to breastfeed were Chinese, working women, and/or women from higher income groups. Information on the intended duration of breastfeeding showed that multiparous women and working women did not intend to breastfeed for more than 6 months. Most women did not believe that either breast milk or powdered milk alone was sufficient for infants up to 5 months of age, and intended to supplement with solid food before that age. Since 93.2% of the respondents had already decided on feeding methods by their last trimester, it is important that nutritional information be given during this time. PMID:12280344

    This study was conducted to determine the composition and source apportionment of surfactant in atmospheric aerosols around urban and semi-urban areas in Malaysia based on ionic compositions. Colorimetric analysis was undertaken to determine the concentrations of anionic surfactants as Methylene Blue Active Substances (MBAS) and cationic surfactants as Disulphine Blue Active Substances (DBAS) using a UV spectrophotometer. Ionic compositions were determined using ion chromatography for cations (Na(+), NH4(+), K(+), Mg(2+), Ca(2+)) and anions (F(-), Cl(-), NO3(-), SO4(2-)). Principle component analysis (PCA) combined with multiple linear regression (MLR) were used to identify the source apportionment of MBAS and DBAS. Results indicated that the concentrations of surfactants at both sampling sites were dominated by MBAS rather than DBAS especially in fine mode aerosols during the southwest monsoon. Three main sources of surfactants were identified from PCA-MLR analysis for MBAS in fine mode samples particularly in Kuala Lumpur, dominated by motor vehicles, followed by soil/road dust and sea spray. Besides, for MBAS in coarse mode, biomass burning/sea spray were the dominant source followed by motor vehicles/road dust and building material. PMID:23336924

    This paper presents the mechanical function and characterization of an artificial lightweight geopolymer aggregate (ALGA) using LUSI (Sidoarjo mud) and alkaline activator as source materials. LUSI stands for LU-Lumpur and SI-Sidoarjo, meaning mud from Sidoarjo which erupted near the Banjarpanji-1 exploration well in Sidoarjo, East Java, Indonesia on 27 May 2006. The effect of NaOH molarity, LUSI mud/Alkaline activator (LM/AA) ratio, and Na2SiO3/NaOH ratio to the ALGA are investigated at a sintering temperature of 950 °C. The results show that the optimum NaOH molarity found in this study is 12 M due to the highest strength (lowest AIV value) of 15.79% with lower water absorption and specific gravity. The optimum LUSI mud/Alkaline activator (LM/AA) ratio of 1.7 and the Na2SiO3/NaOH ratio of 0.4 gives the highest strength with AIV value of 15.42% with specific gravity of 1.10 g/cm3 and water absorption of 4.7%. The major synthesized crystalline phases were identified as sodalite, quartz and albite. Scanning Electron Microscope (SEM) image showed more complete geopolymer matrix which contributes to highest strength of ALGA produced. PMID:26006238

    The Malaysian state of Penang consists of the Island of Penang and the adjacent mainland Province Wellesley. Its total area is 1044 square kilometers and its total population is 776,000. The island population is 65% Chinese and 21% Malay; the mainland population is 44.5% Chinese and 43% Malay. Although Penang, like Malaysia as a whole, has suffered violent racial conflict between the Malays and the Chinese in the past, the future for the whole of the nation, including Penang, seems promising. Some racial inequality, however, continues to exist. The main industries of Penang are fishing (now in a depressed state through overexploitation of the fisheries), electronics manufacture, and tourism, which has not been deterred by some degree of environmental pollution. Relations between Georgetown, the state capital, and Kuala Lumpur are generally good, although there is routine rivalry for national development funds, and Penang's Chief Minister frequently prefers to look to Singapore for his inspiration as well as his practical guidance in undertaking programs relating to public housing, industrialization, and social welfare. At the same time Penang represents an alluring place for Singaporean investment. PMID:12179857

    At the 7th conference of the parties to the Convention on Biological Diversity (CBD-COP7, Kuala Lumpur, 2004) it was agreed to establish a global network of marine and coastal protected areas by 2012. The defined objectives of this MPA-network are based on the ecosystem approach: to protect biodiversity and other ecological values, and to ensure sustainable use. The (inter)national policy guidelines state that the selection of MPAs should be based on scientific information and ecological criteria only. As a signatory to the Convention, the Netherlands is now faced with meeting this obligation, and the process of designating the first Marine Protected Areas (MPAs) in the Dutch part of the North Sea is currently in progress. We focus on the science-policy interactions that are part of this Dutch MPA selection process. By taking a closer look at the contemporary site selection process as well as its historical background, we show that ecological, socio-economic and political considerations cannot always be easily separated. Uncertainty is high and the ultimate selection and delimitation of candidate sites rather seems to be the result of a balancing act between ecological, socio-economic and political interests, in which scientific and policy guiding procedures blend with ad-hoc political decision making, and with expert judgment in cases where data is lacking. As such, this paper presents an example of present-day environmental policy making in action.

    Climate change mitigation in developing economies is a balancing act, between economic development and environmental sustainability. The need for market friendly determinants for low carbon economy, without compromising economic development is of essence. The aim of the study is to determine market friendly factors, which motivates voluntary carbon information disclosure, in the real estate industry. The study modeled economic factor with three variables and financial market factor with three variables against voluntary carbon information disclosure in the real estate industry. Structural equation modeling was used for the modeling and content analysis was used to collect data on the level of voluntary carbon information disclosure, from 2013 annual reports of 126 real estate sector companies listed in the Kuala Lumpur Stock Exchange (KLSE). The model achieved a good fit, and was acceptable prediction. The results show that financial market factor has a significant predictive influence on voluntary carbon disclosure. The application of the result is that financial market factor is has a significantly positive influence on companies’ willingness to make voluntary carbon disclosure in the real estate industry. The result may be limited to the real estate industry that is highly leveraged on syndicated fund.

    Numerous studies are demonstrating that engaging undergraduate students in original research can improve their achievement in the science, technology, engineering, and mathematics (STEM) fields and increase the likelihood that some of them will decide to pursue careers in these disciplines. Associated with this increased prominence of research in the undergraduate curriculum are greater expectations from funders, colleges, and universities that faculty mentors will help those students, along with their graduate students and postdoctoral fellows, develop an understanding and sense of personal and collective obligation for responsible conduct of science (RCS). This Feature describes an ongoing National Research Council (NRC) project and a recent report about educating faculty members in culturally diverse settings (Middle East/North Africa and Asia) to employ active-learning strategies to engage their students and colleagues deeply in issues related to RCS. The NRC report describes the first phase of this project, which took place in Aqaba and Amman, Jordan, in September 2012 and April 2013, respectively. Here we highlight the findings from that report and our subsequent experience with a similar interactive institute in Kuala Lumpur, Malaysia. Our work provides insights and perspectives for faculty members in the United States as they engage undergraduate and graduate students, as well as postdoctoral fellows, to help them better understand the intricacies of and connections among various components of RCS. Further, our experiences can provide insights for those who may wish to establish "train-the-trainer" programs at their home institutions.

    Male osteoporosis in Malaysia is a largely neglected problem. Therefore, a bone health study in men using quantitative ultrasonometry was launched as part of the Malaysian Aging Men Study in 2009–2012. This review aimed to summarize the findings of the aforementioned bone health study. The study examined the bone health of Chinese and Malaysian men aged 20 years and above living in Kuala Lumpur using a quantitative ultrasound device. Participants answered a questionnaire on their demographic details and physical activity status. Body anthropometry of the participants was measured and their blood collected for biochemical analysis. Results showed that a significant proportion of the Malaysian Chinese and Malay men had suboptimal bone health indicated by calcaneal speed of sound and vitamin D status. Age-related decline of the calcaneal speed of sound in these men was gradual and biphasic without ethnic difference. Body anthropometry such as height, weight, body mass index, and body fat percentage contributed to the variation of the calcaneal speed of sound in Malaysian men. Age-related changes in testosterone, insulin-like growth factor 1, and thyroid stimulating hormone also influenced the calcaneal speed of sound in these men. This study serves as a reminder that male osteoporosis in Malaysia should be an issue of concern. It is also a basis for a more comprehensive study on bone health in men in the future. PMID:27231930

    Two studies examined correlates of belief in a Jewish conspiracy theory among Malays in Malaysia, a culture in which state-directed conspiracism as a means of dealing with perceived external and internal threats is widespread. In Study 1, 368 participants from Kuala Lumpur, Malaysia, completed a novel measure of belief in a Jewish conspiracy theory, along with measures of general conspiracist ideation, and anomie. Initial analysis showed that the novel scale factorially reduced to a single dimension. Further analysis showed that belief in the Jewish conspiracy theory was only significantly associated with general conspiracist ideation, but the strength of the association was weak. In Study 2, 314 participants completed the measure of belief in the Jewish conspiracy theory, along with measures of general conspiracist ideation, and ideological attitudes. Results showed that belief in the Jewish conspiracy theory was associated with anti-Israeli attitudes, modern racism directed at the Chinese, right-wing authoritarianism, and social dominance orientation. General conspiracist ideation did not emerge as a significant predictor once other variables had been accounted for. These results suggest that there may be specific cultural and social psychological forces that drive belief in the Jewish conspiracy theory within the Malaysian context. Specifically, belief in the Jewish conspiracy theory among Malaysian Malays appears to serve ideological needs and as a mask for anti-Chinese sentiment, which may in turn reaffirm their perceived ability to shape socio-political processes.

    Prospects for a stable, prospering economy in Malaysia appear threatened by an uneven distribution of wealth among non-Malay, particularly Chinese, residents. Native Malays, Bumiputra, have benefitted from the government's 20 year New Economic Policy, a system of subsidies to correct economic imbalances among the races. Malay corporate ownership has increased from 2.4% in 1970 to 28% in 1979. However, equity must increase by 26% annually to meet NEP targets. Without the GNP expanding 7-8% yearly, the government will be tempted to acquire assets at low prices. 70% of the total Malay ownership was held by public enterprises holding equity in trust. An elite group of Bumiputra will own a fair number of shares reserved by 1970. 1/5 of the population of Kuala Lumpur are squatters. Among these groups, communal tension is high. The Chinese businessmen are most resistant to native management. Since they control private domestic investment, they have political power. The Industrial Coordination Act (ICA), which gives power to civil servants through a licensing system, protects the system. The Asian Foundation supports management training, business development, and university demonstration projects in legal aid, solar energy, and community psychiatry. Malaysian competence in English enables widespread distribution of the Books for Asia program.

    In a prospective, observational study, 380 women attending a family planning (LPPKN) clinic and Sexually Transmitted Diseases (STD) clinic in Kuala Lumpur between January 2008 and November 2008 were enrolled. Patient information was obtained from the medical records and patients voluntarily completed questionnaires. Three vaginal swabs from the posterior fornix were taken from each patient examined. Different staining methods and cultivation in Diamonds medium were performed on the collected samples. Study subjects recruited in this survey were mostly young, with a geometric mean ages of 37.31 years (LPPKN clinic) and 32.06 years (STD clinic). Malay, Chinese, Indians and others ethnic groups accounted for 91, 4, 2 and 3%, respectively, at the LPPKN clinic. At the STD clinic, almost all subjects were Chinese. The prevalence rate of trichomoniasis was 0.36% at the LPPKN clinic and 0.0% at the STD clinic. Our findings suggested no association between contraceptive methods used and trichomoniasis infection at the LPPKN clinic. At the STD clinic, it was found a high risk for STD acquisition was not associated with trichomoniasis positivity. The data demonstrated the prevalence of trichomoniasis was very low at LPPKN clinic and absent at STD clinic. The high prevalence rates of other STD among sex workers found in this survey suggest the need for more active interventions focused on this group.

    Plasmodium knowlesi is extensively used as an important malaria model and is now recognized as an important cause of human malaria in Malaysia. The strains of P. knowlesi currently used for research were isolated many decades ago, raising concerns that they might no longer be representative of contemporary parasite populations. We derived a new P. knowlesi line (University Malaya line, UM01), from a patient admitted in Kuala Lumpur, Malaysia, and compared it with a human-adapted laboratory line (A1-H.1) derived from the P. knowlesi H strain. The UM01 and A1-H.1 lines readily invade human and macaque (Macaca fascicularis) normocytes with a preference for reticulocytes. Whereas invasion of human red blood cells was dependent on the presence of the Duffy antigen/receptor for chemokines (DARC) for both parasite lines, this was not the case for macaque red blood cells. Nonetheless, differences in invasion efficiency, gametocyte production and the length of the asexual cycle were noted between the two lines. It would be judicious to isolate and characterise numerous P. knowlesi lines for use in future experimental investigations of this zoonotic species. PMID:27097521

    Student-generated videos provide an authentic learning experience for students, enhance motivation and engagement, improve communication skills, and improve collaborative learning skills. This article describes the development and implementation of a student-generated video activity as part of a knowledge, observation, simulation, and experience (KOSE) program at the School of Dentistry, International Medical University, Kuala Lumpur, Malaysia. It also reports the students' perceptions of an activity that introduced first-year dental students (n=44) to clinical scenarios involving patients and dental team aiming to improve professional behavior and communication skills. The learning activity was divided into three phases: preparatory phase, video production phase, and video-watching. Students were organized into five groups and were instructed to generate videos addressing given clinical scenarios. Following the activity, students' perceptions were assessed with a questionnaire. The results showed that 86 percent and 88 percent, respectively, of the students agreed that preparation of the activity enhanced their understanding of the role of dentists in provision of health care and the role of enhanced teamwork. In addition, 86 percent and 75 percent, respectively, agreed that the activity improved their communication and project management skills. Overall, the dental students perceived that the student-generated video activity was a positive experience and enabled them to play the major role in driving their learning process.

    A fulminating extension of rabies-which has been enzootic in northern Malaya since 1924-occurred in Kuala Lumpur in April 1952. The outbreak was suppressed by the compulsory mass vaccination of dogs, stringent legislation, and intensive stray-dog destruction. Similar measures are being employed in the current campaign, the aim of which is the complete eradication of the disease.From an average annual incidence of 112 confirmed canine cases prior to 1952-when a total of 198 cases was reported-the incidence fell to 15 cases (all in unvaccinated dogs) for the period January-November 1953, during the last 5(1/2) months of which no case in either animals or man was reported. It is considered that the extensive publicity campaign and strict enforcement of the control measures have contributed measurably to the present improved position.Statistics relating to confirmed cases in dogs previously vaccinated with (a) phenolized 20% brain-tissue suspension vaccine (buffalo origin) and (b) chicken-embryo vaccine (Flury strain) are quoted and their probable significance in favour of the latter under Malayan conditions is discussed. The hypothesis that the development of rabies may, in many instances, have been blocked by the vaccine is advanced.The plan for a pan-Federation compulsory vaccination campaign in 1954, to consolidate the 1952-3 improvements, is outlined.

    Analysis of the bleeding manifestations of 130 cases of dengue haemorrhagic fever admitted into the Children's ward of the General Hospital, Kuala Lumpur from May 1973 to September 1978 has been done. Petechial skin rash, epistaxis and gum bleeding were seen most commonly in mild and moderately severe cases. However, blood stained gastric aspirates, and severe haematemesis were seen in severe or very severe cases. Though with better vector control and preventive measures, a marked reduction in the incidence of the cases has been noted, severe cases were seen with symptoms of shock and gastrointestinal bleeding. These symptoms carried a bad prognosis. Among 15 children that died 10 had gastrointestinal bleeding and 2 had a disseminated intravascular coagulation defect. Lymphocytosis with atypical lymphocytes, low platelet count, low reticulocyte count and raised packed cell volume were the main haematological features seen in all these cases. All these features reverted to normal within a week. Mild evidence of disseminated intravascular coagulation was seen in a number of cases, but severe features were seen only in four. Two cases improved as a result of heparin therapy.

    This study involves the adoption of the Geographic Information System (GIS) modeling approach to determine the quickest routes for fresh vegetable delivery. During transport, fresh vegetables mainly deteriorate on account of temperature and delivery time. Nonetheless, little attention has been directed to transportation issues in most areas within Kuala Lumpur. In addition, perishable food normally has a short shelf life, thus timely delivery significantly affects delivery costs. Therefore, selecting efficient routes would consequently reduce the total transportation costs. The regression model is applied in this study to determine the parameters that affect route selection with respect to the fastest delivery of fresh vegetables. For the purpose of this research, ArcGIS software with network analyst extension is adopted to solve the problem of complex networks. The final output of this research is a map of quickest routes with the best delivery times based on all variables. The variables tested from regression analysis are the most effective parameters to make the flow of road networks slower. The objective is to improve the delivery services by achieving the least drive time. The main findings of this research are that Land use such as residential area and population as variables are the effective parameters on drive time.

    The aims of the study were to determine the prevalence of peripheral arterial disease (PAD) in diabetic patients and in different ethnic groups at a primary care setting, and to evaluate risk factors associated with PAD in these diabetic patients. A cross sectional study of 200 diabetic patients over 18 years old who attended a primary care clinic at a teaching hospital in Kuala Lumpur, Malaysia was carried out. Face-to-face interviews were conducted using structured questionnaires for demographic characteristics and risk factors evaluation. Blood pressure measurements, assessment of peripheral neuropathy and ankle brachial pressures were performed. PAD was diagnosed by an ankle brachial pressure index (ABPI) of <0.9 on either leg. The overall prevalence of PAD was 16% in this diabetic population. The prevalence of PAD was 5.8% in Malays, 19.4% in Chinese and 19.8% in Indians. The prevalence of peripheral neuropathy was 41%, foot ulcer 9.5%, and gangrene 3.0%. The presence of foot ulcer was weakly associated with PAD (P=0.052). No significant relationships were found between age, gender, smoking status, duration of diabetes mellitus, hypertension, dyslipidaemia, and PAD. PAD is common in the diabetic population of this study. PMID:18705445

    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 centers, 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 and 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.

    Background A cross sectional survey was carried out on 120 hospitalised geriatric patients aged 60 and above in Hospital Universiti Kebangsaan Malaysia, Kuala Lumpur to investigate their nutrient intakes and food preferences. Methods Food intakes were recorded using a one day weighed method and diet recall. Food preferences were determined using a five point hedonic score. Food wastages and factors affecting dietary adequacy were also investigated. Results The findings indicated that the mean intakes of energy and all nutrients investigated except for vitamin C and fluid were below the individual requirement for energy, protein and fluid, and the Malaysian Recommendation of Dietary Allowances (RDA) for calcium, iron, vitamin A, thiamin, riboflavin, niacin and acid ascorbic. In general, subjects preferred vegetables, fruits and beans to red meat, milk and dairy products. There was a trend of women to have a higher percentage for food wastage. Females, diabetic patients, subjects who did not take snacks and subjects who were taking hospital food only, were more likely to consume an inadequate diet (p < 0.05 for all values). Conclusions Food service system in hospital should consider the food preferences among geriatric patients in order to improve the nutrient intake. In addition, the preparation of food most likely to be rejected such as meat, milk and dairy products need some improvements to increase the acceptance of these foods among geriatric patients. This is important because these foods are good sources of energy, protein and micronutrients that can promote recovery from disease or illness. PMID:12165100

    Transboundary haze episodes caused by seasonal forest fires have become a recurrent phenomenon in Southeast Asia, with serious environmental, economic, and public health implications. Here we present a cross-sectional survey conducted among people in Kuala Lumpur and surrounds to assess the links between knowledge, attitudes, and practices in relation to the transboundary haze episodes. Of 305 respondents, 125 were amateur athletes participating in a duathlon event and the remainder were surveyed in an inner-city shopping mall. Across the whole sample, people who possessed more factual information about the haze phenomenon showed significantly higher levels of concern. Duathletes were more knowledgeable than non-duathletes and also more concerned about the negative effects of haze, especially on health. For all people who regularly practice outdoor sports (including people interviewed at the shopping mall), higher levels of knowledge and concerned attitudes translated into a greater likelihood of engaging in protective practices, such as cancelling their outdoor training sessions, while those with greater knowledge were more likely to check the relevant air pollution index on a daily basis. Our results indicate that the provision of accurate and timely information about air quality to residents will translate into beneficial practices, at least among particularly exposed individuals, such as amateur athletes who regularly practice outdoor sports.

    The levels of labor force participation by women in selected Asian countries were recorded in a series of censuses taken over a period of years. These levels were less influenced than male employment levels by economic conditions and more influenced by cultural traits of the country. Postwar trends seem to have fallen in Korea, risen in Singapore and the Philippines, and remained steady in Japan, Malaya, and Thailand. The limitations of these data are mentioned. In Thailand and West Malaysia greater percentages of women worked in agricultural than non-agricultural employment; in the Philippines, where women did not work so much in agricultural pursuits, their jobs were still in traditional rather than in development industries. In the cities of Bangkok, Manila, and Kuala Lumpur, fertility was lower for working than for non-working women. In rural agricultural areas, the fertility of working women was minimally higher, probably due to economic need of lar ger families. It is concluded that urban life separates the employment and the family roles of working women, leading to lowered fertility; this does not occur in rural areas. The creation of new roles for women alternative or supplementary to marriage and motherhood would result in lowered fertility. In high fertility Asian countries, policies directed toward greater participation of women in non-agricultural work and great er exposure to an urban lifestyle might achieve fertility reductions.

    Increasing frequency, intensity, and geographic distribution of Harmful algal blooms (HABs) poses a serious threat to the coastal fish/shellfish aquaculture and fisheries in Malaysian bays. Rising in sea level, shoreline erosion, stresses on fisheries, population pressure, interference of land-use and lack of institutional capabilities for integrated management make major challenges. Recent investigations and satellite observations indicate HABs originated from specific coast that have favourable geographic, geomorphic and coastal geology conditions to bring the green macro algae from the coast offshore. Therefore, the identification of high HABs frequented bays using remote sensing and geology investigations in Malaysian waters is required to reduce future challenges in this unique case. This research implemented comprehensive geomorphic and coastal geology investigations combined with remote sensing digital image processing approach to identify Malaysian bays frequented with HABs occurrence in Malaysian waters territory. The landscape and geomorphological features of the Malaysian bays were constructed from the Phased Array type L-band Synthetic Aperture Radar (PALSAR) remote sensing satellite data combined with field observations and surveying. The samples for laboratory analysis were collected from the sediment stations with different distance across shorelines features and watersheds of the Johor Bahru estuary. This research identified that semi-enclosed bays such as Kuala Lumpur and Johor Bahru bays with connection to estuaries have high potential to be frequented with HABs occurrence.

    The air pollution index (API) is an important figure used for measuring the quality of air in the environment. The API is determined based on the highest average value of individual indices for all the variables which include sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3), and suspended particulate matter (PM10) at a particular hour. API values that exceed the limit of 100 units indicate an unhealthy status for the exposed environment. This study investigates the risk of occurrences of API values greater than 100 units for eight urban areas in Peninsular Malaysia for the period of January 2004 to December 2014. An extreme value model, known as the generalized Pareto distribution (GPD), has been fitted to the API values found. Based on the fitted model, return period for describing the occurrences of API exceeding 100 in the different cities has been computed as the indicator of risk. The results obtained indicated that most of the urban areas considered have a very small risk of occurrence of the unhealthy events, except for Kuala Lumpur, Malacca, and Klang. However, among these three cities, it is found that Klang has the highest risk. Based on all the results obtained, the air quality standard in urban areas of Peninsular Malaysia falls within healthy limits to human beings.

    Banking system plays an important role in the economic development of any country. Domestic banks, which are the main components of the banking system, have to be efficient; otherwise, they may create obstacle in the process of development in any economy. This study examines the technical efficiency of the Malaysian domestic banks listed in the Kuala Lumpur Stock Exchange (KLSE) market over the period 2005–2010. A parametric approach, Stochastic Frontier Approach (SFA), is used in this analysis. The findings show that Malaysian domestic banks have exhibited an average overall efficiency of 94 percent, implying that sample banks have wasted an average of 6 percent of their inputs. Among the banks, RHBCAP is found to be highly efficient with a score of 0.986 and PBBANK is noted to have the lowest efficiency with a score of 0.918. The results also show that the level of efficiency has increased during the period of study, and that the technical efficiency effect has fluctuated considerably over time. PMID:22900009

    The survey of Thysanoptera in peninsular Malaysia has been concentrated largely in areas growing crops and flowers around Kuala Lumpur, and the Cameron Highlands, and there are few records of these insects from native forests particularly in the northern part of the country. The two species described here were collected during a recent visit to Belum-Temengor Forest Complex, in Perak State, part of the second largest forested area on the peninsular, and connected to the Bang Lang National Park, in Yala Province, Thailand. This forest has been well known as home to a number of endangered animals, including Malayan tigers and Asian elephants, as well as remarkable plant species such as Rafflesia with the world's largest flowers (Abdullah et al. 2011). Despite this, forest areas are facing a major challenge from the insatiable demand for timber, palm oil and minerals, with an 80% increase in deforestation rate in Malaysia between 1990 and 2005 (FAO 2010). Forested land in peninsular Malaysia has been estimated at 5.88 million-ha or 44% of total area, but the coverage of reserved virgin forest is about 0.40 % or 23,002-ha (Dahlan 2008). PMID:27394331

    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. PMID:19124314

    This article describes the homicide pattern in Penang Island, Malaysia over a three-year period (2007-2009). 65 homicide autopsies were performed at the Department of Forensic Medicine, Penang Hospital over the study period. The homicide rates ranged from 0.01 to 0.09/1000 population, the highest being in the Indian ethnic group. The majority (37%) of victims were in the 20-39 years age group. The male: female ratio was 3:1. The majority of deaths were caused by blunt instruments (46%), followed by stab/slash wounds (25%) and asphyxiation (12%). 63% of homicides occurred in areas served by the police stations at Jalan Patani (23.1%), Sg. Nibong (16.9%), Central (12.3%) and Bayan Lepas (10.9%). 56 (86%) victims were brought in dead to the hospital, while 9 (14%) died after admission. Most (39%) incidences occurred in the morning. The methods of homicide were different from Kuala Lumpur, another highly urbanised area of Malaysia.

    INTRODUCTION This study aimed to determine the risk factors of diabetic Charcot arthropathy of the foot among diabetic patients with and without foot problems. METHODS This was a case-control study involving diabetic patients attending the Diabetic Foot Care and Wound Management Clinic at University Malaya Medical Centre, Kuala Lumpur, Malaysia, from June 2010 to June 2011. Data on sociodemographic profiles, foot factors and diabetes characteristics was collected and analysed. RESULTS A total of 48 diabetic patients with Charcot arthropathy of the foot were identified. Data from these 48 patients was compared with those of 52 diabetic patients without foot problems. Up to 83.3% of patients with diabetic Charcot arthropathy presented with unilateral Charcot foot, most commonly located at the midfoot (45.8%). Patients with a history of foot problems, including foot ulcer, amputation, surgery or a combination of problems, had the highest (26-time) likelihood of developing Charcot arthropathy (odds ratio 26.4; 95% confidence interval 6.4–109.6). Other significant risk factors included age below 60 years, more than ten years’ duration of diabetes mellitus and the presence of nephropathy. CONCLUSION A history of prior diabetic foot problems is the greatest risk factor for developing diabetic Charcot arthropathy, compared with other risk factors such as diabetes characteristics and sociodemographic profiles. Preventive management of diabetic foot problems in the primary care setting and multidisciplinary care are of paramount importance, especially among chronic diabetic patients. PMID:27075668

    141 salivary gland lesions that were subjected to fine needle aspiration (FNA) cytology at the University Hospital, Kuala Lumpur, from January 1993 to October 2000 were reviewed with a view to assess the sensitivity and utility of cytological diagnosis in diseases of salivary glands. The highest number of cases was seen in the sixth decade of life. There was no gender preponderance in salivary gland neoplasms except in Warthin's tumours that occurred predominantly in males. The parotid gland was the most frequent salivary gland needled. Seven cases (5%) presented with bilateral salivary gland enlargement. Cytological study yielded a neoplastic diagnosis in 74.5% cases. Of the neoplastic lesions, 71.4% could be definitely designated as benign and 25.7% as clearly malignant. Pleomorphic adenoma and acinic cell carcinoma were the most common benign and malignant neoplasms diagnosed respectively. 53 cases had histological correlation; of these, 49 (92.5%) were neoplastic. The overall diagnostic accuracy of FNA cytological diagnosis in salivary gland lesions was found to be 73.6%.

    Background: Digital mammography is slowly replacing screen film mammography. In digital mammography, 2 methods are available in acquiring images: digital storage phosphor plate and full-field digital mammography. The aim of this study was to compare the image quality acquired from the 2 methods of digital mammography in the detection of breast cancer. Methods: The study took place at the National Cancer Society, Kuala Lumpur, and followed 150 asymptomatic women for the duration of 1 year. Participating women gave informed consent and were exposed to 4 views from each system. Two radiologists independently evaluated the printed images based on the image quality criteria in mammography. McNemar’s test was used to compare the image quality criteria between the systems. Results: The agreement between the radiologists for the digital storage phosphor plate was к = 0.551 and for full-field digital mammography was к = 0.523. Full-field digital mammography was significantly better compared with the digital storage phosphor plate in right and left mediolateral oblique views (P < 0.05) in the detection of microcalcifications, which are early signs of breast cancer. However, both systems were comparable in all other aspects of image quality. Conclusion: Digital mammography is a useful screening tool for the detection of early breast cancer and ensures better prognosis and quality of life. PMID:22977375

    A cross-sectional study was carried out on 8,478 consecutive normal singleton Malaysian neonates born in the Maternity Hospital, Kuala Lumpur. The objectives were to compare the mean birth-weights, crown-heel lengths and head circumferences of Malay, Chinese and Indian infants at gestation age from 28 to 42 weeks, and to construct the Malaysian growth charts. Above the gestation age of 34 weeks, the birthweights were significantly influenced by maternal gravida status (p < 0.03), ethnic origin (p < 0.001) and/or sex of the neonates (p < 0.026). Above this gestation age, neonates of multigravida mothers were significantly heavier than those of primigravida mothers; Indians were significantly lighter than Malays and Chinese; and males were significantly heavier than females. The head circumferences and body lengths of neonates were significantly influenced by ethnic origin, sex and/or maternal gravida status at gestation above 35 and 36 weeks respectively (p < 0.05). It was most likely due to the small sample size which explained our inability to detect statistically significant difference in all measurements (birthweight, length and head circumference) by sex, ethnicity and maternal gravida status at gestation below 35 weeks. Based on the measurements obtained in this study, percentile charts for the Malaysian population were constructed and made available for the first time. These charts will be useful for the assessment of Malaysian neonates during the perinatal period.

    This study examines the usefulness of the "CAGE", (which is an acronym for "cut down", "annoyed", "guilty" and "eye-opener"), a 4-question screening test to identify excessive drinkers among Malaysian inpatients. The CAGE questionnaire after translation and back translation was administered to all inpatients in the General Hospital, Kuala Lumpur. The author interviewed 'blindly' all who score positive on the CAGE score and 10% of all negatives using the DSM III interview schedule for alcohol abuse dependence. The results show that the CAGE performs best at a cut-off point of 2 and above, with a sensitivity of 92%, specificity of 62%, positive predictive values of 38% and Kappa (K) of 0.37 with a DSM III R diagnosis for alcohol abuse/dependence. The poor agreement with a DSM III diagnosis indicates that the CAGE is not useful in the Malaysian population. Reasons suggested for this are: cultural factors in the Malaysian population resulting in the overrating of the question of 'guilt' by Muslims and translations into the local languages which are only the closest approximations.

    After-school programs are prevalent across the world, but there is a paucity of research that examines quality within the "black box" of programs at the point of service. Grounded in current theory, this research examined hypothesized pathways between the experience of youth-adult partnership (youth voice in decision-making; supportive adult relationships), the mediators of program safety and engagement, and the developmental outcomes of youth empowerment (leadership competence, policy control) and community connectedness (community connections, school attachment). Surveys were administered to 207 ethnically diverse (47.3 % female; 63.3 % Malay) youth, age 15-16, attending after-school co-curricular programs in Kuala Lumpur, Malaysia. Results showed that youth voice in program decision-making predicted both indicators of youth empowerment. Neither youth voice nor supportive adult relationships was directly associated with community connectedness, however. Program engagement mediated the associations between youth-adult partnership and empowerment. In contrast, program safety mediated the associations between youth-adult partnership and community connectedness. The findings indicate that the two core components of youth-adult partnership-youth voice and supportive adult relationships-may operate through different, yet complementary, pathways of program quality to predict developmental outcomes. Implications for future research are highlighted. For reasons of youth development and youth rights, the immediate challenge is to create opportunities for youth to speak on issues of program concern and to elevate those adults who are able and willing to help youth exercise their voice.

    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. PMID:27187889

    This article highlights methods of ending life in different ethnic groups. This inference is drawn from analysis of data from suicidal cases from the University Malaya Medical Centre mortuary. This study also looked at sex, age, social, and employment factors. Kuala Lumpur has sizeable populations of Muslims, Chinese, Indians and Indonesian, etc. This study is based on 251 cases of suicide that were reported at the University Malaya Medical Centre from 2000 to 2004. Malaysia has a population of 22,662,365 people with 3 major ethnic groups: Malay (58%), Chinese (24%), and Indians (8%) with a minority of "others" (10%), which includes foreigners, Sabahan, and Sarawakian. This research found suicides of 164 male (65%) and 87 female (35%) victims. Their age ranged from 15 to 80 years. The age group from 21 to 30 had the highest total cases of suicide (83 of 251; 33.1%). Among ethnic groups highest rate of suicide was among Chinese with a total of 120 cases (120 of 251; 47.8%). As far as lone method of suicide is concerned, hangings accounted for the highest proportion of cases (108 of 251; 43%). Among ethnic groups, jumping from height was the commonest method used by Chinese (49 of 120; 41%), Malay (9 of 16; 56%), and others (15 of 28; 53.4%); whereas, hanging was the commonest method of committing suicide by Indians (49 of 87); Muslims showed the lowest cases of suicide (18 of 251; 7.2%). In poisoning group Indian was the highest ethnic group who used this method (20 of 37; 54.1%). PMID:19749611

    Objectives: The aim of this study was to determine the content validity, internal consistency, test-retest reliability and inter-rater reliability of the Clinical Competency Evaluation Instrument (CCEVI) in assessing the clinical performance of physiotherapy students. Methods: This study was carried out between June and September 2013 at University Kebangsaan Malaysia (UKM), Kuala Lumpur, Malaysia. A panel of 10 experts were identified to establish content validity by evaluating and rating each of the items used in the CCEVI with regards to their relevance in measuring students’ clinical competency. A total of 50 UKM undergraduate physiotherapy students were assessed throughout their clinical placement to determine the construct validity of these items. The instrument’s reliability was determined through a cross-sectional study involving a clinical performance assessment of 14 final-year undergraduate physiotherapy students. Results: The content validity index of the entire CCEVI was 0.91, while the proportion of agreement on the content validity indices ranged from 0.83–1.00. The CCEVI construct validity was established with factor loading of ≥0.6, while internal consistency (Cronbach’s alpha) overall was 0.97. Test-retest reliability of the CCEVI was confirmed with a Pearson’s correlation range of 0.91–0.97 and an intraclass coefficient correlation range of 0.95–0.98. Inter-rater reliability of the CCEVI domains ranged from 0.59 to 0.97 on initial and subsequent assessments. Conclusion: This pilot study confirmed the content validity of the CCEVI. It showed high internal consistency, thereby providing evidence that the CCEVI has moderate to excellent inter-rater reliability. However, additional refinement in the wording of the CCEVI items, particularly in the domains of safety and documentation, is recommended to further improve the validity and reliability of the instrument.

    Infections caused by multidrug resistant Klebsiella pneumoniae have been increasingly reported in many parts of the world. A total of 93 Malaysian multidrug resistant K. pneumoniae isolated from patients attending to University of Malaya Medical Center, Kuala Lumpur, Malaysia from 2010-2012 were investigated for antibiotic resistance determinants including extended-spectrum beta-lactamases (ESBLs), aminoglycoside and trimethoprim/sulfamethoxazole resistance genes and plasmid replicons. CTX-M-15 (91.3%) was the predominant ESBL gene detected in this study. aacC2 gene (67.7%) was the most common gene detected in aminoglycoside-resistant isolates. Trimethoprim/sulfamethoxazole resistance (90.3%) was attributed to the presence of sul1 (53.8%) and dfrA (59.1%) genes in the isolates. Multiple plasmid replicons (1-4) were detected in 95.7% of the isolates. FIIK was the dominant replicon detected together with 13 other types of plasmid replicons. Conjugative plasmids (1-3 plasmids of ~3-100 kb) were obtained from 27 of 43 K. pneumoniae isolates. An ESBL gene (either CTX-M-15, CTX-M-3 or SHV-12) was detected from each transconjugant. Co-detection with at least one of other antibiotic resistance determinants [sul1, dfrA, aacC2, aac(6ˊ)-Ib, aac(6ˊ)-Ib-cr and qnrB] was noted in most conjugative plasmids. The transconjugants were resistant to multiple antibiotics including β-lactams, gentamicin and cotrimoxazole, but not ciprofloxacin. This is the first study describing the characterization of plasmids circulating in Malaysian multidrug resistant K. pneumoniae isolates. The results of this study suggest the diffusion of highly diverse plasmids with multiple antibiotic resistance determinants among the Malaysian isolates. Effective infection control measures and antibiotic stewardship programs should be adopted to limit the spread of the multidrug resistant bacteria in healthcare settings. PMID:26203651

    Health economics, a special branch of science applying economic principles to the health delivery system, is a relatively young subdiscipline. The literature is scanty about teaching health economics in the medical and dental fields. Delivery methods of this topic vary from one university to another, with lectures, seminars, and independent learning reported as teaching/learning tools used for the topic. Ideally, debates should foster the development of logical reasoning and communication skills. Health economics in dentistry is taught under the community oral health module that constitutes part of an outcome-based dental curriculum in a private dental school in Kuala Lumpur, Malaysia. For this study, the students were divided into two groups: active participants (active debaters) and supporting participants (nonactive debaters). The debate style chosen for this activity was parliamentary style. Active and nonactive debaters' perceptions were evaluated before and after the activity through a structured questionnaire using a five-point rating scale addressing the topic and perceptions about debate as an educational tool. Cronbach's alpha coefficient was used as a measure of internal consistency for the questionnaire items. Among a total of eighty-two third-year dental students of two successive cohorts (thirty-eight students and forty-four students), seventy-three completed the questionnaire, yielding a response rate of 89 percent. Students' responses to the questionnaire were analyzed with the Kruskal-Wallis analysis of variance test. Results revealed that the students felt that their interest in debate, knowledge of the topic, and reinforcement of the previous knowledge had improved following participation in the debate. Within the limitations of this study, it can be concluded that debate was a useful tool in teaching health economics to dental students.

    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 < 0.05). Practice was associated significantly with age, marital status, and geographic area (p < 0.05) and knowledge on 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.

    Several lines of evidence have indicated that the Mentawai segment of the Sumatran megathrust is very likely to rupture within the next few decades. The present study is to investigate seismic hazard and risk levels at major cities in Sumatra, Java, Singapore and the Malay Peninsula caused by the potential giant earthquakes. Two scenarios are considered. The first one is an Mw 8.6 earthquake rupturing the 280-km segment that has been locked since 1797; in the second scenario, rupture occurs along a 400-km segment covering the combined rupture areas of the 1797 and 1833 historical events, of which the southern portion has partially slipped on 12 and 13 September 2007, producing an Mw 8.8 earthquake. Simulation results indicate that ground motions produced by the hypothetical scenarios are strong enough to cause yielding to medium and high-rise buildings in many major cities in Sumatra. It is vital to ensure that the overall strength, stiffness and integrity of the structures are maintained throughout the entire duration of shaking. However, the ductile detailing in current practice is formulated based on an assumption that ground motions would last 20 to 40 seconds. This has not been tested for longer durations of three to five minutes, expected from giant earthquakes. In Singapore and Kuala Lumpur, only medium and high-rise buildings, especially those located on soft-soil sites, are at risk. Given that seismic design has not been required in both cities, and thus the resulting structures are relatively brittle, it is crucial to investigate their performance under moderate-amplitude, long-duration, ground motions. The present study also points out that the shift of response spectrum toward longer period range becomes prominent for sites located far from potential seismic sources, which should be carefully considered in formulation of future seismic codes for Singapore, Malaysia and Indonesia.

    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.

    Factors influencing condom acceptance were studied and compared in 2 groups of condom-acceptors--those using condoms as a 1st method of contraception and those using condoms as an alternative method of contraception. Data was obtained by reviewing the condom-acceptor cards during 1981-1987 at the General Hospital in Kuala Lumpur, Malaysia; 208 cards for the 1st group and 230 for the 2nd group were included in the study. Statistical analysis was conducted to determine characteristics influencing condom-use. AGe of wife, duration of marriage, number of living children, wife's level of education and socioeconomic status were identified as factors influencing condom acceptance. No significant difference was observed between the 2 group concerning their purpose of contraception. Age of wife had a significant influence on the use of condoms as contraception. Age of wife had a significant influence on the use of condoms as contraception; 74.5% of group 1 users were 31 years and 56.5% of group 2 users were 30 years. A very significant relationship also exist between condom use and duration of marriage and number of living children; condom-acceptors using condoms as the 1st method of contraception did so within 9 years of marriage (85.6%) and practiced condom use when they had 2 of children (73.6%) while those who used condoms subsequently were married 10 years (46.5%) and did so after having 3 or children (57.8%). Significant differences were observed between groups in higher socioeconomic status and higher level of education. With 7 or more years of education, a significant proportion of condom-acceptors used condoms as a 1st method of contraception as compared with those who used it as a subsequent method of contraception. For the higher socioeconomic, a significant number of acceptors used condoms as a 1st method of contraception.

    The CARIBIC project (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container, www.caribic-atmospheric.com) aims to investigate the spatial and temporal distribution of a wide-range of compounds, including those of marine origin/influence, via ~monthly flights to collect in situ data and whole air samples aboard a commercial Lufthansa aircraft. CARIBIC measures up to an altitude of 12 km, allowing the influence of marine compounds on the upper troposphere/lower stratosphere (UTLS) to be explored. In particular, CARIBIC is a useful tool for exploring the impact of very short lived halocarbons (e.g. CH2Br2, CHBr3), whose impact on stratospheric ozone is dependent on convective uplift to the UTLS, a process which is not yet fully quantified. As part of the suite of CARIBIC measurements, whole air samples are analysed at the University of East Anglia (UEA) via gas chromatography mass spectrometry for carbonyl sulphide (OCS) and up to 40 halocarbons (accounting for virtually 100% of organic chlorine, bromine and iodine in the UTLS). Here we present an overview of short-lived halocarbons and OCS measured by CARIBIC. We focus on two regions of particular interest. (1) measurements made in 2012 over the tropical west Pacific to link with UEA measurements made during the SHIVA campaign. (2) measurements made during a collection of flights over India in 2008. Flights over India investigated the impact of monsoon circulation on the distribution of these compounds; for example, elevated concentrations of OCS were seen in CARIBIC samples taken over India during the summer monsoon (July - September). These flights, along with a wider range of flights over Asia (from Frankfurt to Guangzhou, Manila, Bangkok and Kuala Lumpur) can provide unique information on the influence of tropical convection and monsoon circulation on halocarbon and OCS transport within this region.

    At about 1.00 a.m. on 24 September, 1981, at km 24.5 of the Kuala Lumpur-Karak highway, there occurred a failure of a 26 m high slope cut into the weathering profile developed over a porphyritic biotite granite. The failure, which is best classified a slump-flow, occurred some 5.7 years after the end of excavation and involved the downslope movement of about 2000 m 3 of weathered bedrock material (mainly gravelly silty sands) and a few coreboulders. Continued movement of failed material through minor slumping and gulleying led to eventual exposure of the failure surface which was mainly located along a relict fault plane striking parallel to, and dipping 48° towards, the highway. Failure occurred as a result of several converging factors; the triggering factor being ground vibrations set up at the time of passing of three large trucks. Conditions of instability, however, were already present in the slope materials through infiltration of rainwater that led to saturation and the loss of apparent or effective cohesion. Infiltration had been encouraged by clearing of vegetation at the top of the cut and the creation of a track along its western edge some 6 months prior to failure. Infiltration was also encouraged by rainfall patterns with the failure occurring after some 29 days with almost continuous daily rainfall; this wet period being preceded by an unusual 27 days of no rain. It is concluded that stability assessments of slope cuts in weathering profiles over granitic bedrock need to take into consideration not only shear strength parameters, but also local climatic and other environmental factors, including likely triggering factors.

  17. Spectral Discrimination of Fine and Coarse Mode Aerosol Optical Depth from AERONET Direct Sun Data of Singapore and South-East Asia

    Aerosol optical depth combined with the Angstrom exponent and its derivative, are often used as a qualitative indicator of aerosol particle size, with Angstrom exp. values greater than 2 indicating small (fine mode) particles associated with urban pollution and bio-mass burning. Around this region, forest fires are a regular occurrence during the dry season, specially near the large land masses of Sumatra and Borneo. The practice of clearing land by burning the primary and sometimes secondary forest, results in a smog-like haze covering large areas of regional cities such as cities Singapore, Kuala Lumpur and sometimes the south of Thailand, often reducing visibility and increasing health problems for the local population. In Singapore, the sources of aerosols are mostly from fossil fuel burning (energy stations, incinerators, urban transport etc.) and from the industrial and urban areas. The proximity to the sea adds a possible oceanic source. However, as stated above and depending on the time of the year, there can be a strong bio-mass component coming from forest fires from various regions of the neighboring countries. Bio-mass related aerosol particles are typically characterized by showing a large optical depth and small, sub-micron particle size distributions. In this work, we analyze three years of direct Sun measurements performed with a multi-channel Cimel Sun-Photometer (part of the AERONET network) located at our site. In order to identify bio-mass burning events in this region, we perform a spectral discrimination between coarse and fine mode optical depth; subsequently, the fine mode parameters such as optical depth, optical ratio and fine mode Angstrom exponents (and its derivative) are used to identify possible bio-mass related events within the data set.

    Decadal changes in shortwave irradiance at the Earth's surface are estimated for the period from approximately 1960 through to 2000 from pyranometer records stored in the Global Energy Balance Archive. For this observational period, estimates could be calculated for a total of 140 cells of the International Satellite Cloud Climatology Project grid (an equal area 2.5° × 2.5° grid at the equator) using regression models allowing for station effects. In large regions worldwide, shortwave irradiance decreases in the first half of the observational period, recovers from the decrease in the 1980s, and thereafter increases, in line with previous reports. Years of trend reversals are determined for the grid cells which are best described with a second-order polynomial model. This reversal of the trend is observed in the majority of the grid cells in the interior of Europe and in Japan. In China, shortwave irradiance recovers during the 1990s in the majority of the grid cells in the southeast and northeast from the decrease observed in the period from 1960 through to 1990. A reversal of the trend in the 1980s or early 1990s is also observed for two grid cells in North America, and for the grid cells containing the Kuala Lumpur (Malaysia), Singapore, Casablanca (Morocco), Valparaiso (Chile) sites, and, noticeably, the remote South Pole and American Samoa sites. Negative trends persist, i.e., shortwave radiation decreases, for the observational period 1960 through to 2000 at the European coasts, in central and northwest China, and for three grid cells in India and two in Africa.

    This article uses methodology based on chi-squared automatic interaction detection (CHAID), as a multivariate method that has an automatic classification capacity to analyse large numbers of landslide conditioning factors. This new algorithm was developed to overcome the subjectivity of the manual categorization of scale data of landslide conditioning factors, and to predict rainfall-induced susceptibility map in Kuala Lumpur city and surrounding areas using geographic information system (GIS). The main objective of this article is to use CHi-squared automatic interaction detection (CHAID) method to perform the best classification fit for each conditioning factor, then, combining it with logistic regression (LR). LR model was used to find the corresponding coefficients of best fitting function that assess the optimal terminal nodes. A cluster pattern of landslide locations was extracted in previous study using nearest neighbor index (NNI), which were then used to identify the clustered landslide locations range. Clustered locations were used as model training data with 14 landslide conditioning factors such as; topographic derived parameters, lithology, NDVI, land use and land cover maps. Pearson chi-squared value was used to find the best classification fit between the dependent variable and conditioning factors. Finally the relationship between conditioning factors were assessed and the landslide susceptibility map (LSM) was produced. An area under the curve (AUC) was used to test the model reliability and prediction capability with the training and validation landslide locations respectively. This study proved the efficiency and reliability of decision tree (DT) model in landslide susceptibility mapping. Also it provided a valuable scientific basis for spatial decision making in planning and urban management studies.

    This study is to review the impact of climate change and land used on flooding through the Klang River and 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 centre of Kuala Lumpur. Klang River Basin is the most urbanized region in Malaysia. More than half of the basin has been urbanized on the land that is prone to flooding. Numerous flood mitigation projects and studies have been carried out to enhance the existing flood forecasting and mitigation project. The objective of this study is to develop a hydrological model for flood forecasting in Klang Basin Malaysia. Hydrological modelling generally requires large set of input data and this is more often a challenge for a developing country. Due to this limitation, the Tropical Rainfall Measuring Mission (TRMM) rainfall measurement, initiated by the US space agency NASA and Japanese space agency JAXA was used in this study. TRMM data was transformed and corrected by quantile to quantile transformation. However, transforming the data based on ground measurement doesn't make any significant improvement and the statistical comparison shows only 10% difference. The conceptual HYMOD model was used in this study and calibrated using ROPE algorithm. But, using the whole time series of the observation period in this area resulted in insufficient performance. The depth function which used in ROPE algorithm are then used to identified and calibrated using only unusual event to observed the improvement and efficiency of the model.
