  1. Fulltext Epidemiologic update on the dengue situation in the Western Pacific Region, 2011
    Arima Y, Edelstein ZR, Han HK, Matsui T
    Western Pac Surveill Response J, 2013 May 14;4(2):47-54.
    PMID: 24015372 DOI: 10.5365/WPSAR.2012.3.4.019
    Dengue is an emerging vectorborne infectious disease that is a major public health concern in the Asia and the Pacific. Official dengue surveillance data for 2011 provided by ministries of health were summarized as part of routine activities of the World Health Organization Regional Office for the Western Pacific. Based on officially reported surveillance data, dengue continued to show sustained activity in the Western Pacific Region. In 2011, Member States reported a total of 244,855 cases of which 839 died for a case fatality rate of 0.34%. More than 1000 cases were reported each from Cambodia, the Federated States of Micronesia, the Lao People's Democratic Republic, Malaysia, the Philippines, the Marshall Islands, Singapore and Viet Nam. Cambodia, the Federated States of Micronesia and the Marshall Islands reported higher activity relative to 2010. There continues to be great variability among the dengue-endemic countries and areas in the Region in the number of cases and serotype distribution. The continued high notification rate and complex dengue epidemiology in the Region highlight the need for information-sharing on a routine and timely basis.

  2. Evidence of a reversal of the breastfeeding decline in Peninsular Malaysia
    Haaga JG
    Am J Public Health, 1986 Mar;76(3):245-51.
    PMID: 3946711
    Data from the Malaysian Family Life Survey show an increase in the percentage of infants breastfed, at least initially, from 75 per cent in 1970-74 to 79 per cent in 1975-77. Contrary to what would be expected if Malaysia were following the trends observed in the United States and Western Europe, the increase has occurred among poor and uneducated women as well as among the more fortunate. The increase was especially marked for infants born in hospitals and private clinics, which had very low rates of breastfeeding in the early 1970s. The change may be due partly to a shift in the practices and recommendations of health professionals. Trends in infant feeding practices in Malaysia during the whole period 1950-77 are reviewed. Reasons for thinking the increase in the mid-1970s an artifact of the survey are presented and provisionally rejected. The implications of these findings for child health policy in Malaysia and for theories of infant feeding trends in developing countries are discussed.

  3. Fulltext Dengue fever in Malaysia: time for review?
    Kumarasamy V
    Med J Malaysia, 2006 Mar;61(1):1-3.
    PMID: 16708726
    Dengue is the most important arthropod borne viral disease of public health significance. Compared to nine reporting countries in the 1950's, today the geographical distribution includes more than 100 countries world wide. The WHO estimates that more than 2.5 billion people are at risk of dengue infections, with 50 million cases occurring annually with 22,000 deaths'. The dengue virus is an enveloped single stranded RNA of the family Flaviridae. There are four serotypes which share genetic and antigenic features but infection with the one serotype does not provide long-term protection against other serotypes. The principal vector is the day biting Aedes aegypti which typically breeds in clean stagnant water in a wide variety of sites including man made containers in the domestic and peridomestic urban environment

  4. Reference ranges of handgrip strength from 125,462 healthy adults in 21 countries: a prospective urban rural epidemiologic (PURE) study
    Leong DP, Teo KK, Rangarajan S, Kutty VR, Lanas F, Hui C, et al.
    J Cachexia Sarcopenia Muscle, 2016 12;7(5):535-546.
    PMID: 27104109
    BACKGROUND: The measurement of handgrip strength (HGS) has prognostic value with respect to all-cause mortality, cardiovascular mortality and cardiovascular disease, and is an important part of the evaluation of frailty. Published reference ranges for HGS are mostly derived from Caucasian populations in high-income countries. There is a paucity of information on normative HGS values in non-Caucasian populations from low- or middle-income countries. The objective of this study was to develop reference HGS ranges for healthy adults from a broad range of ethnicities and socioeconomically diverse geographic regions.

    METHODS: HGS was measured using a Jamar dynamometer in 125,462 healthy adults aged 35-70 years from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study.

    RESULTS: HGS values differed among individuals from different geographic regions. HGS values were highest among those from Europe/North America, lowest among those from South Asia, South East Asia and Africa, and intermediate among those from China, South America, and the Middle East. Reference ranges stratified by geographic region, age, and sex are presented. These ranges varied from a median (25th-75th percentile) 50 kg (43-56 kg) in men <40 years from Europe/North America to 18 kg (14-20 kg) in women >60 years from South East Asia. Reference ranges by ethnicity and body-mass index are also reported.

    CONCLUSIONS: Individual HGS measurements should be interpreted using region/ethnic-specific reference ranges.

    Yasin RM, Jegathesan MM, Tiew CC
    Asia Pac J Public Health, 1996;9:1-5.
    PMID: 10050191
    From January 1983 to December 1992 a total of 20,874 salmonella were serotyped in the Bacteriology Division IMR, which showed an increase of 100% compared to the previous ten-years. There were 97 serotypes which belonged to 22 Kauffmann-white groups. Twenty two serotypes hitherto were seen in this study period. S. typhi was the commonest serotype isolated. Overall there was a rise in the isolation of non-typhoidal salmonella particularly S. enteritidis which increased by 760% and S. blockley which increased by 720%. However there is a drop in the isolation of S typhimurium by 223% and S. paratyphi B by 319%.

  7. Field studies on the surveillance of Coquillettidia crassipes (Van der Wulp) and the isolation of a strain of Cardiofilaria in peninsular Malaysia
    Chiang GL, Samarawickrema WA, Eng KL, Cheong WH, Sulaiman I, Yap HH
    Ann Trop Med Parasitol, 1986 Apr;80(2):235-44.
    PMID: 2875691
    Surveillance methods for Coquillettidia crassipes were studied in an open housing estate near Kuala Lumpur using three types of traps Trinidad 10 trap, modified Lard can trap and IMR trap, each baited with chicken or pigeon. All traps attracted Cq. crassipes. There was no significant difference in the catches in the three traps. There was also no significant difference between chicken and pigeon as bait. Catches at heights of 1.5, 3, 4.5 and 6 m did not show any significant difference in density. Cq. crassipes was active at night with an early peak during the first hour of the night and a minor peak between 0100 and 0200 hours. The activity of the parous and nulliparous sections of the population was similar, except that a higher proportion of the parous females was active during the second peak compared with the nulliparous females. The parous rate was 22.3%, and the probability of survival through one day for two gonotrophic cycles was 0.711 and 0.650. The infection rate for Cardiofilaria was 29 out of 1052 (2.76%) and the infective rate (L3 larvae) was 13 out of 1052 (1.24%). 48.3% of the infected Cq. crassipes had a worm burden of more than ten larvae. One of the chickens in the traps was positive for microfilariae of Cardiofilaria four weeks after exposure as bait. Laboratory bred Cq. crassipes fed on this chicken produced infective larvae in ten days, and these were inoculated into clean chickens and pigeons. Microfilariae appeared in the chickens but not in pigeons. The adult worms recovered await identification.

    Kesy A
    Pol J Vet Sci, 2002;5(4):283-7.
    PMID: 12512564
    This article reviews the actual world FMD situation. In 2000, fifty nine countries officially reported outbreaks of FMD. The disease occurred in Europe (Greece), Asia (Russia, Mongolia, Bangladesh, Cambodia, China, Japan, Laos, Nepal, Pakistan, Philippines, Republic of Korea, Taiwan, Thailand, Vietnam, Iran, Iraq, Turkey, in Caucasian region--Georgia, Azerbaijan and Armenia as well as in Kazakhstan, Kyrgyzstan, Turkmenistan and Tajikistan), Africa (Egypt, Kenya, Mauritania, South Africa, Tanzania, Uganda, Malawi, Namibia, Zambia and Zimbabwe) and in South America (Brazil, Colombia, Uruguay, Bolivia, Peru, Ecuador and Venezuela). In 2001, FMD was still spreading throughout the endemic regions and appeared in some of the west European countries--Great Britain, The Netherlands, France and Ireland. In South America, FMD occurred in Argentina, Uruguay, Brazil and Colombia. In Asia the FMD spread in Turkey, Iran, Afghanistan, Georgia, Azerbaijan, Mongolia, Kuwait, Bahrain, Yemen, Qatar, United Arab Emirates, Oman, Iran, Bhutan, Nepal, Malaysia, Philippines, Thailand and Taiwan. The FMD situation in Africa was unclear, but probably most countries in West, East and South Africa were affected. The most recent data of the OIE from May 2002 confirmed FMD outbreaks in population of pigs in Republic of Korea.

  11. Fulltext Assessing the efficiency of Malaysia health system in COVID-19 prevention and treatment response
    Md Hamzah N, Yu MM, See KF
    Health Care Manag Sci, 2021 Jun;24(2):273-285.
    PMID: 33651316 DOI: 10.1007/s10729-020-09539-9
    Malaysia was faced with a life-threatening crisis in combating COVID-19 with a number of positive cases reaching 5305 and 88 deaths by 18th April 2020 (the first detected case was on 25th January 2020). The government rapidly initiated a public health response and provided adequate medical care to manage the public health crisis during the implementation of movement restrictions, starting 18th March 2020, throughout the country. The objective of this study was to investigate the relative efficiency level of managing COVID-19 in Malaysia using network data envelopment analysis. Malaysia state-level data were extracted from secondary data sources which include variables such as total number of confirmed cases, death cases and recovered cases. These variables were used as inputs and outputs in a network process that consists of 3 sub processes i) community surveillance, ii) medical care I and iii) medical care II. A state-level analysis was performed according to low, medium and high population density categories. The efficiency level of community surveillance was highest compared to medical care processes, indicating that the overall inefficiency is greatly influenced by the inefficiency of the medical care processes rather than the community surveillance process. Results showed that high-density category performed well in both community surveillance and medical care II processes. Meanwhile, low-density category performed better in medical care I process. There was a good overall performance of the health system in Malaysia reflecting a strong preparedness and response level to this pandemic. Furthermore, resource allocation for rapid response was distributed effectively during this challenging period.

  12. Access to pathology and laboratory medicine services: a crucial gap
    Wilson ML, Fleming KA, Kuti MA, Looi LM, Lago N, Ru K
    Lancet, 2018 05 12;391(10133):1927-1938.
    PMID: 29550029 DOI: 10.1016/S0140-6736(18)30458-6
    As global efforts accelerate to implement the Sustainable Development Goals and, in particular, universal health coverage, access to high-quality and timely pathology and laboratory medicine (PALM) services will be needed to support health-care systems that are tasked with achieving these goals. This access will be most challenging to achieve in low-income and middle-income countries (LMICs), which have a disproportionately large share of the global burden of disease but a disproportionately low share of global health-care resources, particularly PALM services. In this first in a Series of three papers on PALM in LMICs, we describe the crucial and central roles of PALM services in the accurate diagnosis and detection of disease, informing prognosis and guiding treatment, contributing to disease screening, public health surveillance and disease registries, and supporting medical-legal systems. We also describe how, even though data are sparse, these services are of both insufficient scope and inadequate quality to play their key role in health-care systems in LMICs. Lastly, we identify four key barriers to the provision of optimal PALM services in resource-limited settings: insufficient human resources or workforce capacity, inadequate education and training, inadequate infrastructure, and insufficient quality, standards, and accreditation.

  13. Fulltext Surveillance of antimicrobial resistance in low- and middle-income countries: a scattered picture
    Iskandar K, Molinier L, Hallit S, Sartelli M, Hardcastle TC, Haque M, et al.
    Antimicrob Resist Infect Control, 2021 03 31;10(1):63.
    PMID: 33789754 DOI: 10.1186/s13756-021-00931-w
    Data on comprehensive population-based surveillance of antimicrobial resistance is lacking. In low- and middle-income countries, the challenges are high due to weak laboratory capacity, poor health systems governance, lack of health information systems, and limited resources. Developing countries struggle with political and social dilemma, and bear a high health and economic burden of communicable diseases. Available data are fragmented and lack representativeness which limits their use to advice health policy makers and orientate the efficient allocation of funding and financial resources on programs to mitigate resistance. Low-quality data means soaring rates of antimicrobial resistance and the inability to track and map the spread of resistance, detect early outbreaks, and set national health policy to tackle resistance. Here, we review the barriers and limitations of conducting effective antimicrobial resistance surveillance, and we highlight multiple incremental approaches that may offer opportunities to strengthen population-based surveillance if tailored to the context of each country.

  15. Fulltext Epidemiology, surveillance and control of Nipah virus infections in Malaysia
    Chua KB
    Malays J Pathol, 2010 Dec;32(2):69-73.
    PMID: 21329176 MyJurnal
    The outbreak of Nipah virus, affecting pigs and pig-farm workers, was first noted in September 1998 in the north-western part of peninsular Malaysia. By March 1999, the outbreak had spread to other pig-farming areas of the country, inclusive of the neighbouring country, Singapore. A total of 283 human cases of viral encephalitis with 109 deaths were recorded in Malaysia from 29 September 1998 to December 1999. During the outbreak period, a number of surveillances under three broad groups; Surveillance in Human Health Sector, Surveillance in Animal Health Sector, and Surveillance for the Reservoir Hosts, were carried out to determine the prevalence, risk of virus infections and transmission in human and swine populations as well as the source and reservoir hosts of Nipah virus. Surveillance data showed that the virus spread rapidly among pigs within infected farms and transmission was attributed to direct contact with infective excretions and secretions. The spread of the virus among pig farms within and between states of peninsular Malaysia was due to movement of pigs. The transmission of the virus to humans was through close contact with infected pigs. Human to human transmission was considered a rare event though the Nipah virus could be isolated from saliva, urine, nasal and pharyngeal secretions of patients. Field investigations identified fruitbats of the Pteropid species as the natural reservoir hosts of the viruses. The outbreak was effectively brought under control following the discovery of the virus and institution of correct control measures through a combined effort of multi-ministerial and multidisciplinary teams working in close co-operation and collaboration with other international agencies.

  16. Sociodemographic and health-lifestyle determinants of obesity risks in Malaysia
    Tan AK, Dunn RA, Samad MI, Feisul MI
    Asia Pac J Public Health, 2011 Apr;23(2):192-202.
    PMID: 20460299 DOI: 10.1177/1010539509359535
    The purpose of this study was to examine the sociodemographic and health-lifestyle factors that affect the likelihood of obesity among Malaysians. Data were obtained from the Malaysian Non-Communicable Disease Surveillance-1. The cross-sectional population-based survey consisted of 2447 observations, with an obesity prevalence rate of 17.2%. Based on logit regression analysis, the results suggest that obesity risks in Malaysia are affected by gender, education level, family history, health conditions, smoking status, and ethnic backgrounds. Specifically, Malaysians more likely to be obese are females (5.3%), lower educated (0.9%), those with history of family illnesses (4.8%), and nonsmokers (6.4%). However, Chinese (9.3%) and other (5.5%) ethnic groups are less likely to be obese when compared with Malays. Based on these results, several policy implications are discussed vis-à-vis obesity risks in Malaysia.

    PMID: 19842408
    In Malaysia, the two dose measles - mumps - rubella (MMR) vaccine was introduced in the Expanded Program on Immunization in 2002. The Ministry of Health then initiated a measles elimination strategy which included enhanced case-based surveillance with laboratory testing of all suspected cases. The objective of our study was to analyse national measles laboratory data from 2004 to 2008 to study the impact of the nationwide strategy on measles case incidence. Blood samples collected from suspected measles cases during the acute stage of the illness were investigated for measles specific IgM. The estimated incidence of measles ranged from 22.3 cases (in 2004) to 2.27 cases (in 2006) per 100,000 population. During this time, the measles vaccination coverage was above 85%. Laboratory confirmed measles cases dropped from 42.2% in 2004, when sporadic outbreaks were reported, to 3.9% in 2007. Screening for measles IgG levels in 2008 showed that 82.8% of those > 7 years old had adequate immunity. The measles control strategy appears to have been successful in reducing the incidence of measles. Continuing high vaccination coverage rates and ongoing measles surveillance are necessary to achieve our goal of measles elimination.

    PMID: 19227674
    To create a nationwide system to capture data on completed suicide in Malaysia i.e. the morbidity, geographic and temporal trends and the population at high risk of suicide. Data from this registry can later be used to stimulate and facilitate further research on suicide. This paper describes the rationale and processes involved in developing a national suicide registry in 2007. The diagnosis of suicide is based on the ICD-10 codes for fatal intentional self-harm (X60-X84). A case report form with an accompanying instruction manual had been prepared to ensure systematic and uniform data collection. State Forensic Pathologist's offices are responsible for data collection in their respective states, and in turn will submit the data to a central data management unit. Data collection began in July 2007 and currently in data cleaning process. Training for source data producers is ongoing. In 2008, the NSRM plans to involve university hospitals into its network as currently only Ministry of Health hospitals are involved. The NSRM will be launching its online application for case registration this year while an overview of results will be available via its public domain at www.nsrm.gov.my beginning 20 April 2008. To efficiently capture the data on suicide, a concerted effort between various agencies is needed. A lot of conceptual work and data base development remains to be done in order to position preventive efforts on a more solid foundation.

    In Malaysia, Diabetes in Children and Adolescents Registry (DiCARE) was launched nationwide in August 2006 to determine and monitor the number, the time trend of diabetes mellitus (DM) patients, their socio-demographic profiles, outcome of intervention and facilitate research using this registry. This is an on going real time register of diabetic patients < or = 20 years old via the e-DiCARE, an online registration system. To date were 240 patients notified from various states in Malaysia. The mean age was 12.51 years (1.08-19.75) and 46.4% were boys. The mean age at diagnosis was 8.31 +/- 4.13 years old with an estimated duration of diabetes of 4.32 +/- 3.55 years. A total of 166/240 (69.2%) have T1DM, 42/240 (17.5%) have T2DM and 18/240 (7.5%) have other types of DM. Basis of diagnosis was known in 162 patients with T1DM and 41 patients with T2DM. In T1DM patients, 6.0% of the girls and 19.1% boys were overweight or obese. As for T2DM, 64.3% had their BMI reported: 66.7% girls and 91.6% boys were overweight or obese. Most patients (80.4%) practiced home blood glucose monitoring. Patients were seen by dietitian (66.7%), diabetes educator (50.0%), and optometrist or ophthalmologist (45.0%). Only 10.8% attended diabetic camps. In the annual census of 117 patients, the mean HbAlc level was 10.0% + 2.2 (range 5.2 to 17.0%). The early results of DiCARE served as a starting point to improve the standard of care of DM among the young in the country.

    Med J Malaysia, 2008 Sep;63 Suppl C:24-8.
    PMID: 19230243
    Diabetic Eye Registry, a web based registry hosted at the National Eye Database (www.acrm.org.my/end) collects data in a systematic and prospective nature on status of diabetic retinopathy (DR) among diabetics seen for the first time at Ministry of Health ophthalmology clinics. The 2007 report on 10,586 diabetics revealed that 63.3% of eyes examined had no DR, 36.8% had any form of DR, of which 7.1% had proliferative diabetic retinopathy. Up to 15.0% of eyes had vision threatening DR requiring laser or surgery at their first visit. Data on diabetic eye registry is useful in monitoring the quality of diabetic management, particularly in eye screening as reflected by the proportion of patients with severe DR needing intervention at the first visit to Ophthalmology clinics.
