Prevalence and predictors for musculoskeletal discomfort in Malaysian office workers: Investigating explanatory factors for a developing country

Maakip I, Keegel T, Oakman J

Appl Ergon, 2016 Mar;53 Pt A:252-7.
PMID: 26499952 DOI: 10.1016/j.apergo.2015.10.008

Musculoskeletal disorders (MSDs) are a major occupational health issue for workers in developed and developing countries, including Malaysia. Most research related to MSDs has been undertaken in developed countries; given the different regulatory and cultural practices it is plausible that contributions of hazard and risk factors may be different. A population of Malaysian public service office workers were surveyed (N = 417, 65.5% response rate) to determine prevalence and associated predictors of MSD discomfort. The 6-month period prevalence of MSD discomfort was 92.8% (95%CI = 90.2-95.2%). Akaike's Information Criterion (AIC) analyses was used to compare a range of models and determine a model of best fit. Contributions associated with MSD discomfort in the final model consisted of physical demands (61%), workload (14%), gender (13%), work-home balance (9%) and psychosocial factors (3%). Factors associated with MSD discomfort were similar in developed and developing countries but the relative contribution of factors was different, providing insight into future development of risk management strategies.

The value of life and accident costing: a willingness-to-pay study amongst motorcyclists in Malaysia

Mohd Fauzi MY, Nor Ghani MN, Radin Umar RS, Ahmad Hariza H

Appl Health Econ Health Policy, 2004;3(1):5-8.
PMID: 15702934

Motorcyclists constitute a large proportion of total road casualties in Asian countries Unfortunately, studies conducted for the purpose of evaluating the cost of traffic crashes, and cost-benefit analyses of safety interventions, are almost nonexistent in these countries. The loss-of-output approach to valuing life has been used for many years, yet this method has also long been criticised as it results in significant resource misallocation. This study attempts to overcome this problem by estimating the value of a statistical life among motorcyclists using the willingness-to-pay method that is commonly used in developed countries. The study recommends adopting a value of MYR1.1 million (almost five times the previous estimate) per statistical life for public policy analysis involving motorcycle safety.

Fulltext Absence of nucleotide alteration in region of exon 34 of NOTCH1 and NOTCH2 receptor genes analysed in oral cancer samples: a preliminary observation

Nor Nasyitah Ismail, Khairani Idah Mokhtar

Archives of Orofacial Sciences, 2010;5(1):17-23.
MyJurnal

Oral cancer is one of the common cancer cases identified in the developing countries. Genetic mutation and overexpression of certain genes and proteins have been associated in the development of this cancer. Notch signalling pathway is normally involved in controlling the development process of vertebrates and invertebrates; however, deregulation of this pathway was found to be responsible in the formation of certain cancers including oral cancers. Activation of this pathway requires binding of the ligands to its receptors. Four NOTCH receptors (NOTCH 1, 2, 3 and 4) have been identified in mammals. Disruptions within these molecules might interfere with the normal functions of Notch signalling pathway. Hence, this study was conducted to detect mutations of NOTCH1 and NOTCH2 receptor genes which might be occurring in the oral cancer cases obtained from the local population. DNA extracted from fresh-frozen tissue biopsy of the tongue and buccal mucosa from 10 confirmed cases of oral cancer were subjected for polymerase chain reaction (PCR) amplification using the specific sets of primers. The PCR products were sent for sequencing before final results were analysed.
Due to time and cost limitation, only two out of four NOTCH receptor genes; NOTCH1 and NOTCH2, were used in this analysis. The results revealed absence of nucleotide changes for both NOTCH receptor genes amplified from these oral cancer samples. More samples and further analysis looking into other regions in these genes are required to conclude the involvement of NOTCH receptor genes mutation in causing oral cancer.

Withdrawal and limitation of life support in paediatric intensive care

Goh AY, Lum LC, Chan PW, Bakar F, Chong BO

Arch Dis Child, 1999 May;80(5):424-8.
PMID: 10208946

OBJECTIVES: To compare the modes of death and factors leading to withdrawal or limitation of life support in a paediatric intensive care unit (PICU) in a developing country.
METHODS: Retrospective analysis of all children (< 12 years) dying in the PICU from January 1995 to December 1995 and January 1997 to June 1998 (n = 148).
RESULTS: The main mode of death was by limitation of treatment in 68 of 148 patients, failure of active treatment including cardiopulmonary resuscitation in 61, brain death in 12, and withdrawal of life support with removal of endotracheal tube in seven. There was no significant variation in the proportion of limitation of treatment, failure of active treatment, and brain death between the two periods; however, there was an increase in withdrawal of life support from 0% in 1995 to 8% in 1997-98. Justification for limitation was based predominantly on expectation of imminent death (71 of 75). Ethnic variability was noted among the 14 of 21 patients who refused withdrawal. Discussions for care restrictions were initiated almost exclusively by paediatricians (70 of 75). Diagnostic uncertainty (36% v 4.6%) and presentation as an acute illness were associated with the use of active treatment.
CONCLUSIONS: Limitation of treatment is the most common mode of death in a developing country's PICU and active withdrawal is still not widely practised. Paediatricians in developing countries are becoming more proactive in managing death and dying but have to consider sociocultural and religious factors when making such decisions.

Levels, temporal trends, and tissue distribution of perfluorinated surfactants in freshwater fish from Asian countries

Murakami M, Adachi N, Saha M, Morita C, Takada H

Arch Environ Contam Toxicol, 2011 Nov;61(4):631-41.
PMID: 21424221 DOI: 10.1007/s00244-011-9660-4

Perfluorinated surfactants (PFSs) in Asian freshwater fish species were analyzed to investigate tissue distribution, temporal trends, extent of pollution, and level of PFS exposure through food intake. Freshwater fish species, namely carp, snakehead, and catfish, were collected in Japan, Vietnam, India, Malaysia, and Thailand, and 10 PFSs, including perfluorooctanesulfonate (PFOS) and perfluorooctanoate, were analyzed by liquid chromatography-tandem mass spectrometry. PFSs in carp in Tokyo were more concentrated in kidneys (Σ10 PFSs = 257 ± 95 ng/g wet weight [ww]) and livers (119 ± 36 ng/g ww) than in ovaries (43 ± 2 ng/g ww) and muscles (24 ± 17 ng/g ww). Concentrations of PFOS and its precursor, perfluorooctane sulfonamide, in livers of carp and in waters in Tokyo showed a dramatic decrease during the last decade, probably because of 3 M's phasing-out of the manufacture of perfluorooctanesulfonyl-fluoride-based products in 2000. In contrast, continuing contamination by long-chain perfluorocarboxylates (PFCAs) with ≥ 9 fluorinated carbons was seen in multiple media, suggesting that these compounds continue to be emitted. PFS concentrations in freshwater fish species in tropical Asian countries were generally lower than those in developed countries, such as Japan, e.g., for PFOS in muscle, Vietnam < 0.05-0.3 ng/g ww; India < 0.05-0.2 ng/g ww; Malaysia < 0.05-0.2 ng/g ww; Thailand < 0.05 ng/g ww; and Japan (Tokyo) = 5.1-22 ng/g ww. Daily intake of short-chain PFCAs with ≤ 8 fluorinated carbons from freshwater fish species in Japan was approximately one order of magnitude lower than that from drinking water, whereas daily intake of PFOS and long-chain PFCAs with ≥ 9 fluorinated carbons from freshwater fish species was comparable with or greater than that from drinking water. Because the risk posed by exposure to these compounds through intake of fish species is a matter of concern, we recommend the continued monitoring of PFS levels in Asian developing countries.

Hip fracture registries in low- and middle-income countries: a scoping review

Klappenbach R, Lartigue B, Beauchamp M, Boietti B, Santero M, Bosque L, et al.

Arch Osteoporos, 2023 Apr 17;18(1):51.
PMID: 37067611 DOI: 10.1007/s11657-023-01241-x

PURPOSE: The study aims to identify, describe, and organize the currently available evidence regarding hip fracture (HF) registries in low- and middle-income countries (LMICs).
METHODS: We conducted a scoping review adhering to PRISMA-ScR guidelines. We searched MEDLINE (PubMed), Google Scholar, Global Index Medicus, websites related to HF, and study references for eligible studies. Two reviewers independently performed the study selection and data extraction, including studies describing the use of individual patient records with the aim to improve the quality of care in older people with HF in LMICs.
RESULTS: A total of 222 abstracts were screened, 59 full-text articles were reviewed, and 10 studies regarding 3 registries were included in the analysis. Malaysia and Mexico implemented a HF registry in public hospitals whereas Argentina implemented a registry in the private setting. The Mexican registry, the most recent one, is the only one that publishes annual reports. There was significant variability in data fields between registries, particularly in functional evaluation and follow-up. The Ministry of Health finances the Malaysian registry, while Argentinian and Mexican registries founding was unclear.
CONCLUSION: The adoption of HF registries in LMICs is scarce. The few experiences show promising results but higher support is required to develop more registries. Long-term sustainability remains a challenge.

Fulltext The prevalence and factors associated with obesity among adult women in Selangor, Malaysia

Sidik SM, Rampal L

Asia Pac Fam Med, 2009 Apr 09;8(1):2.
PMID: 19358728 DOI: 10.1186/1447-056X-8-2

INTRODUCTION: The prevalence of obesity in developing countries especially among women is on the rise. This matter should be taken seriously because it can burden the health care systems and lower the quality of life.
AIM: The purpose of this study was to determine the prevalence of obesity among adult women in Selangor and to determine factors associated with obesity among these women.
METHODS: This community based cross sectional study was conducted in Selangor in January 2004. Multi stage stratified proportionate to size sampling method was used. Women aged 20-59 years old were included in this study. Data was collected using a questionnaire-guided interview method. The questionnaire consisted of questions on socio-demographic (age, ethnicity, religion, education level, occupation, monthly income, marital status), Obstetric & Gynaecology history, body mass index (BMI), and the Patient Health Questionnaire (PHQ-9).
RESULTS: Out of 1032 women, 972 agreed to participate in this study, giving a response rate of 94.2%. The mean age was 37.91 +/- 10.91. The prevalence of obesity among the respondents was 16.7% (mean = 1.83 +/- 0.373). Obesity was found to be significantly associated with age (p = 0.013), ethnicity (p = 0.001), religion (p = 0.002), schooling (p = 0.020), educational level (p = 0.016), marital status (p = 0.001) and the history of suffering a miscarriage within the past 6 months (p = 0.023).
CONCLUSION: The prevalence of obesity among adult women in this study was high. This problem needs to be emphasized as the prevalence of obesity keeps increasing, and will continue to worsen unless appropriate preventive measures are taken.

Fulltext Micronutrient interventions on cognitive performance of children aged 5-15 years in developing countries

Khor GL, Misra S

Asia Pac J Clin Nutr, 2012;21(4):476-86.
PMID: 23017305

It is estimated that more than 200 million young children worldwide fail to reach their potential in cognitive development owing to undernutrition. Numerous studies have assessed the effects of micronutrient supplementation on growth and cognitive development in infants, toddlers and preschoolers. However, micronutrient interventions on the cognitive performance of older children are limited. This article seeks to provide an update on micronutrient interventions and cognitive outcomes among children aged 5-15 years in developing countries. A total of 13 randomized controlled trials published since 2000 were identified. Majority of these studies assessed the effects of micronutrient-fortified foods on various domains of cognitive function. Among key micronutrients assessed were iron, zinc, iodine and vitamin A. This review found a lack of consistency in the impact of micronutrient supplementation on intelligence, long term mental functions and school examination grades of the children. A beneficial effect of micronutrient supplementation on short term memory was more consistently reported. Overall, the evidence from this review for the impact of micronutrients on cognitive performance in older children remains equivocal. In light of the growing interest on the influence of nutrition on cognition, it is important that culturally-appropriate and sufficiently sensitive assessment tools be used for measuring the desired cognitive outcomes that are most likely to be affected by the nutrients under study.

Fulltext Food-based approaches to combat the double burden among the poor: challenges in the Asian context

Khor GL

Asia Pac J Clin Nutr, 2008;17 Suppl 1:111-5.
PMID: 18296315

Estimates of FAO indicate that 14% of the population worldwide or 864 million in 2002-2004 were undernourished in not having enough food to meet basic daily energy needs. Asia has the highest number of undernourished people, with 163 million in East Asia and 300 million in South Asia. Meanwhile obesity and diet-related non-communicable diseases continue to escalate in the region. The double burden of malnutrition also affects the poor, which is a serious problem in Asia, as it has the largest number of poor subsisting on less than $1/day. As poverty in the region is predominantly rural, agriculture-based strategies are important for improving household food security and nutritional status. These measures include shifting toward production of high-value products for boosting income, enhancing agricultural biodiversity, increasing consumption of indigenous food plants and biofortified crops. Urban poor faces additional nutritional problems being more sensitive to rising costs of living, lack of space for home and school gardening, and trade-offs between convenience and affordability versus poor diet quality and risk of contamination. Time constraints faced by working couples in food preparation and child care are also important considerations. Combating the double burden among the poor requires a comprehensive approach including adequate public health services, and access to education and employment skills, besides nutrition interventions.

Fulltext Nutrition and educational achievement of urban primary schoolchildren in Malaysia

Shariff ZM, Bond JT, Johnson NE

Asia Pac J Clin Nutr, 2000 Dec;9(4):264-73.
PMID: 24394502

The relationship between nutrition, health and educational achievement of school-age population in less developed countries has been of interest to many researchers due to the frequent observation that many children did not complete primary school and those who completed, did not do as well as children in the developed countries. Nevertheless, nutritional and health status by itself is not the only variable affecting educational achievement, since biological, psychological, socioeconomic and cultural factors could directly or indirectly affect both nutrition, health status and educational achievement. The mechanism by which health and nutrition influence educational achievement is not well established, but poor health and malnutrition in early childhood may affect cognitive abilities, necessary for learning process and consequently educational achievement. A study was conducted in Kuala Lumpur, Malaysia, to investigate the relationship between nutritional status and educational achievement among primary schoolchildren from low income households (n = 399). A high percentage of them were mild-significantly underweight (52%), stunted (47%) and wasted (36%) and increasingly overweight (6%). In general, more boys than girls were found to experience some form of malnutrition. While weight-for-height did not differ significantly according to family, child and school factors, weight-for-age and height-for-age differed significantly by gender. Also, height-for-age was significantly related to household income. This indicates that stunting may be a consequence of prolonged socioeconomic deprivation. Educational achievement was measured based on test scores for Malay language (ML), English language (EL) and mathematics (MT). While a majority of the schoolchildren obtained optimum scores (>75) for ML and MT, the majority of them had insufficient scores (<50) for EL. Children's total score (TS) for the three subjects was significantly associated with household socioeconomic status, gender, birth order and heightfor- age. Even after controlling for household socioeconomic status, significant association between TS and height-for-age persisted. In this sample of schoolchildren, household income, gender, birth order and height-forage were significant predictors of TS. The finding that height-for-age is related to educational achievement agrees with other studies, which have reported that height-for-age, compared to weight-for-height or weight-forage is linked to educational achievement. Height-for-age reflects the accumulation of nutritional deprivation throughout the years, which may consequently affect the cognitive development of the children.

Estimating radiotherapy demands in South East Asia countries in 2025 and 2035 using evidence-based optimal radiotherapy fractions

Yahya N, Roslan N

Asia Pac J Clin Oncol, 2018 Oct;14(5):e543-e547.
PMID: 29316293 DOI: 10.1111/ajco.12831

BACKGROUND AND PURPOSE: As about 50% of cancer patients may require radiotherapy, the demand of radiotherapy as the main treatment to treat cancer is likely to rise due to rising cancer incidence. This study aims to quantify the radiotherapy demand in countries in Southeast Asia (SEA) in 2025 and 2035 using evidence-based optimal radiotherapy fractions.
MATERIALS AND METHODS: SEA country-specific cancer incidence by tumor site for 2015, 2025 and 2035 was extracted from the GLOBOCAN database. We utilized the optimal radiotherapy utilization rate model by Wong et al. (2016) to calculate the optimal number of fractions for all tumor sites in each SEA country. The available machines (LINAC & Co-60) were extracted from the IAEA's Directory of Radiotherapy Centres (DIRAC) from which the number of available fractions was calculated.
RESULTS: The incidence of cancers in SEA countries are expected to be 1.1 mil cases (2025) and 1.4 mil (2035) compared to 0.9 mil (2015). The number of radiotherapy fractions needed in 2025 and 2035 are 11.1 and 14.1 mil, respectively, compared to 7.6 mil in 2015. In 2015, the radiotherapy fulfillment rate (RFR; required fractions/available fractions) varied between countries with Brunei, Singapore and Malaysia are highest (RFR > 1.0 - available fractions > required fractions), whereas Cambodia, Indonesia, Laos, Myanmar, Philippines, Timor-Leste and Vietnam have RFR

Early phase oncology clinical trials in Malaysia: current status and future perspectives

Voon PJ, Lai WH, Bustaman RS, Siu LL, Razak ARA, Yusof A, et al.

Asia Pac J Clin Oncol, 2023 Jun;19(3):296-304.
PMID: 36305522 DOI: 10.1111/ajco.13886

Historically, the majority of oncology clinical trials are conducted in Western Europe and North America. Globalization of drug development has resulted in sponsors shifting their focus to the Asia-Pacific region. In Malaysia, implementation of various government policies to promote clinical trials has been initiated over a decade ago and includes the establishment of Clinical Research Malaysia, which functions as a facilitator and enabler of industry-sponsored clinical trials on a nationwide basis. Although oncology clinical trials in Malaysia have seen promising growth, there are still only a limited number of early phase oncology studies being conducted. Hence, the Phase 1 Realization Project was initiated to develop Malaysia's early phase clinical trial capabilities. In addition, the adaptation of good practices from other countries contribute to the effective implementation of existing initiatives to drive progress in the development of early phase drug development set up in Malaysia. Furthermore, holistic approaches with emphasis in training and education, infrastructure capacities, strategic alliances, reinforcement of upstream activities in the value chain of drug development, enhanced patient advocacy, coupled with continued commitment from policy makers are imperative in nurturing a resilient clinical research ecosystem in Malaysia.
