  2. Fulltext Potential Health Impacts of Bauxite Mining in Kuantan
    Abdullah NH, Mohamed N, Sulaiman LH, Zakaria TA, Rahim DA
    Malays J Med Sci, 2016 May;23(3):1-8.
    PMID: 27418864
    Bauxite mining is not known to most Malaysian except recently due to environmental pollution issues in Kuantan, Pahang. Potential impacts are expected to go beyond physical environment and physical illness if the situation is not controlled. Loss of economic potentials, and the presence of unpleasant red dust causing mental distress, anger and community outrage. More studies are needed to associate it with chronic physical illness. While evidences are vital for action, merely waiting for a disease to occur is a sign of failure in prevention. All responsible agencies should focus on a wider aspect of health determinants rather than merely on the occurrence of diseases to act and the need to emphasize on sustainable mining to ensure health of people is not compromised.

  3. Fulltext Cultural construction of psychiatric illness in Malaysia
    Razak AA
    Malays J Med Sci, 2017 Mar;24(2):1-5.
    PMID: 28894398 DOI: 10.21315/mjms2017.24.2.1
    The concept of the cultural construction of illness is important in terms of understanding people's behaviour. In this article, this idea is applied to psychiatric illness in Malaysia to explore how it is informed by sociocultural elements, a process that will help us understand the psychiatric expression and help-seeking behaviour of the country's population.

  4. Fulltext Stressors experienced during clinical placement among diploma nursing students in Kolej Poly-tech MARA, Kota Bharu, Kelantan
    Zulainah Osman, Chan, Siok Gim
    The Malaysian Journal of Nursing, 2018;9(3):46-53.
    MyJurnal
    The aim of this project was to determine stress levels and to identify the main stressors that contribute to stress among Kolej Poly-Tech Mara (KPTM) nursing students during their clinical placement in order to help them overcome it. Atotal of 324 respondents undergoing training at KPTM participated in this project. The questionnaire consisting of six common stressors with 30 items using a 5-point Likert Scale was used to measure the level of stress among the respondents during their clinical placement. The data collected was examined for normal distribution, and inferential statistics such as correlations were used to seek relationships. The results indicated that the main stressors that contributed to stress among KPTM nursing students were from both environment, along with assignments and workload. There was moderate level of stress among KPTM nursing students during clinical placement and the factor that contributed to stress was due to the the possibility of making an error. Clinical placement is an essential component for nursing student's training. The practice allows nursing students the opportunity to relate the theory into practice during nursing care towards the patients. Findingsfrom this study will provide the nursing educators, clinical instructors with a meaningful understanding of the importance of clinical placement experience.

  5. Comparison between the development of Malaysian and Denver children
    Chen ST
    J Singapore Paediatr Soc, 1989;31(3-4):178-85.
    PMID: 2638722
    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.

  7. Environmental and genetic determinants of vitamin D insufficiency in 12-month-old infants
    Suaini NH, Koplin JJ, Ellis JA, Peters RL, Ponsonby AL, Dharmage SC, et al.
    J Steroid Biochem Mol Biol, 2014 Oct;144 Pt B:445-54.
    PMID: 25174667 DOI: 10.1016/j.jsbmb.2014.08.018
    We aimed to investigate the relationship between genetic and environmental exposure and vitamin D status at age one, stratified by ethnicity. This study included 563 12-month-old infants in the HealthNuts population-based study. DNA from participants' blood samples was genotyped using Sequenom MassARRAY MALDI-TOF system on 28 single nucleotide polymorphisms (SNPs) in six genes. Using logistic regression, we examined associations between environmental exposure and SNPs in vitamin D pathway and filaggrin genes and vitamin D insufficiency (VDI). VDI, defined as serum 25-hydroxyvitamin D3(25(OH)D3) level ≤50nmol/L, was measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Infants were stratified by ethnicity determined by parent's country of birth. Infants formula fed at 12 months were associated with reduced odds of VDI compared to infants with no current formula use at 12 months. This association differed by ethnicity (Pinteraction=0.01). The odds ratio (OR) of VDI was 0.29 for Caucasian infants (95% CI, 0.18-0.47) and 0.04 for Asian infants (95% CI, 0.006-0.23). Maternal vitamin D supplementation during pregnancy and/or breastfeeding were associated with increased odds of infants being VDI (OR, 2.39; 95% CI, 1.11-5.18 and OR, 2.5; 95% CI, 1.20-5.24 respectively). Presence of a minor allele for any GC SNP (rs17467825, rs1155563, rs2282679, rs3755967, rs4588, rs7041) was associated with increased odds of VDI. Caucasian infants homozygous (AA) for rs4588 had an OR of 2.49 of being associated with VDI (95% CI, 1.19-5.18). In a country without routine infant vitamin D supplementation or food chain fortification, formula use is strongly associated with a reduced risk of VDI regardless of ethnicity. There was borderline significance for an association between filaggrin mutations and VDI. However, polymorphisms in vitamin D pathway related genes were associated with increased likelihood of being VDI in infancy.

  8. The giant mudskipper Periophthalmodon schlosseri facilitates active NH(4)(+) excretion by increasing acid excretion and decreasing NH(3) permeability in the skin
    Ip YK, Randall DJ, Kok TK, Barzaghi C, Wright PA, Ballantyne JS, et al.
    J Exp Biol, 2004 Feb;207(Pt 5):787-801.
    PMID: 14747411
    Periophthalmodon schlosseri is an amphibious and obligatory air-breathing teleost, which is extremely tolerant to environmental ammonia. It actively excretes NH(4)(+) in ammonia loading conditions. For such a mechanism to operate efficaciously the fish must be able to prevent back flux of NH(3). P. schlosseri could lower the pH of 50 volumes (w/v) of 50% seawater in an artificial burrow from pH 8.2 to pH 7.4 in 1 day, and established an ambient ammonia concentration of 10 mmol l(-1) in 8 days. It could alter the rate of titratable acid efflux in response to ambient pH. The rate of net acid efflux (H(+) excretion) in P. schlosseri was pH-dependent, increasing in the order pH 6.0<7.0<8.0<8.5. Net acid flux in neutral or alkaline pH conditions was partially inhibited by bafilomycin, indicating the possible involvement of a V-type H(+)-ATPase. P. schlosseri could also increase the rate of H(+) excretion in response to the presence of ammonia in a neutral (pH 7.0) external medium. Increased H(+) excretion in P. schlosseri occurred in the head region where active excretion of NH(4)(+) took place. This would result in high concentrations of H(+) in the boundary water layer and prevent the dissociation of NH(4)(+), thus preventing a back flux of NH(3) through the branchial epithelia. P. schlosseri probably developed such an 'environmental ammonia detoxification' capability because of its unique behavior of burrow building in the mudflats and living therein in a limited volume of water. In addition, the skin of P. schlosseri had low permeability to NH(3). Using an Ussing-type apparatus with 10 mmol l(-1) NH(4)Cl and a 1 unit pH gradient (pH 8.0 to 7.0), the skin supported only a very small flux of NH(3) (0.0095 micromol cm(-2) min(-1)). Cholesterol content (4.5 micromol g(-1)) in the skin was high, which suggests low membrane fluidity. Phosphatidylcholine, which has a stabilizing effect on membranes, constituted almost 50% of the skin phospholipids, with phosphatidyleserine and phsophatidylethanolamine contributing only 13% and 15%, respectively. More importantly, P. schlosseri increased the cholesterol level (to 5.5 micromol g(-1)) and altered the fatty acid composition (increased total saturated fatty acid content) in its skin lipid after exposure to ammonia (30 mmol l(-1) at pH 7.0) for 6 days. These changes might lead to an even lower permeability to NH(3) in the skin, and reduced back diffusion of the actively excreted NH(4)(+) as NH(3) or the net influx of exogenous NH(3), under such conditions.

  10. Hippocampal neural cell degeneration and memory deficit in high-fat diet-induced postnatal obese rats- exploring the comparable benefits of choline and DHA or environmental enrichment
    Prabhu GS, K G Rao M, Rai KS
    Int J Neurosci, 2021 Nov;131(11):1066-1077.
    PMID: 32498586 DOI: 10.1080/00207454.2020.1773819
    PURPOSE: Childhood obesity increases risk for neural dysfunctions causing learning and memory deficits. The objective of the study is to identify the effects of high fat diet-induced obesity in postnatal period on serum lipids, memory and neural cell survival in hippocampus and compare the role of choline and DHA or environmental enrichment in attenuating the alterations.

    MATERIALS AND METHODS: 21 day postnatal male Sprague Dawley rats were assigned as Normal control [NC] fed normal chow diet, Obesity-induced [OB] fed high fat diet, Obesity-induced fed choline & DHA [OB + CHO + DHA], Obesity-induced environmental enrichment [OB + EE] [n = 8/group]. Memory was assessed using radial arm maze. Subsequently blood was collected for serum lipid analysis and rats were euthanized. 5 µm hippocampal sections were processed for cresyl-violet stain. Surviving neural cells were counted using 100 µm scale.

    RESULTS: Memory errors were significantly higher [p

  12. One world is not enough: the structured phenomenology of lifestyle migrants in East Asia
    Stones R, Botterill K, Lee M, O'Reilly K
    Br J Sociol, 2019 Jan;70(1):44-69.
    PMID: 29479667 DOI: 10.1111/1468-4446.12357
    The paper is based on original empirical research into the lifestyle migration of European migrants, primarily British, to Thailand and Malaysia, and of Hong Kong Chinese migrants to Mainland China. We combine strong structuration theory (SST) with Heideggerian phenomenology to develop a distinctive approach to the interplay between social structures and the lived experience of migrants. The approach enables a rich engagement with the subjectivities of migrants, an engagement that is powerfully enhanced by close attention to how these inner lives are deeply interwoven with relevant structural contexts. The approach is presented as one that could be fruitfully adopted to explore parallel issues within all types of migration. As is intrinsic to lifestyle migration, commitment to a better quality of life is central to the East Asian migrants, but they seek an uncomplicated, physically enhanced texture of life, framed more by a phenomenology of prosaic well-being than of self-realization or transcendence. In spite of possessing economic and status privileges due to their relatively elite position within global structures the reality for a good number of the lifestyle migrants falls short of their prior expectations. They are subject to particular kinds of socio-structural marginaliszation as a consequence of the character of their migration, and they find themselves relatively isolated and facing a distinct range of challenges. A comparison with research into various groups of migrants to the USA brings into relief the specificities of the socio-structural positioning of the lifestyle migrants of the study. Those East Asian migrants who express the greatest sense of ease and contentment seem to be those who have responded creatively to the specific challenges of their socio-structural situation. Often, this appears to have been achieved through understated but active involvements with their new settings and through sustaining focused transnational connections and relationships.

  13. Taboo and Malay tradition
    Teoh JI
    Aust N Z J Psychiatry, 1976 Mar;10(1A):105-10.
    PMID: 1065321
    According to Malinowski there are no peoples, however primitive, without religion and magic; nor are there any societies lacking either in the scientific attitude or in science (Blumberg 1963). Magic and taboo are resorted to when through the normal use of science, or rational techniques, man is unable to control unpredictable events important to him. Where there is difficulty in predicting the outcome of behaviour, where the results of action are not consonant with effort, where there are great limitions on man's knowledge of vital issues, magical techniques are employed--in short, where circumstances of life are uncertain, uncontrolled and unknown. Magic and animism are systems of thought which give not only the explanation of a single phenomenon, but make it possible to comprehend the totality of the world from one point, as a continuity. Of the three systems of thought--animistic, religious and scientific--animism is perhaps the most consistent and the most exhaustive, the one which explains the world in its entirety.

  14. The experiences of suffering of palliative care patients in Malaysia: a thematic analysis
    Beng TS, Guan NC, Seang LK, Pathmawathi S, Ming MF, Jane LE, et al.
    Am J Hosp Palliat Care, 2014 Feb;31(1):45-56.
    PMID: 22956340 DOI: 10.1177/1049909112458721
    A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering in 20 adult palliative care inpatients of University Malaya Medical Centre. The results were thematically analyzed. Ten basic themes were generated (1) loss and change → differential suffering, (2) care dependence → dependent suffering, (3) family stress → empathic suffering, (4) disease and dying → terminal suffering, (5) health care staff encounters → interactional suffering, (6) hospital environment → environmental suffering, (7) physical symptoms → sensory suffering, (8) emotional reactions → emotional suffering, (9) cognitive reactions → cognitive suffering, and (10) spiritual reactions → spiritual suffering. An existential-experiential model of suffering was conceptualized from the analysis. This model may inform the development of interventions in the prevention and management of suffering.

  15. Compositional engineering of VOPcPhO-TiO2nano-composite to reduce the absolute threshold value of humidity sensors
    Azmer MI, Aziz F, Ahmad Z, Raza E, Najeeb MA, Fatima N, et al.
    Talanta, 2017 Nov 01;174:279-284.
    PMID: 28738579 DOI: 10.1016/j.talanta.2017.06.016
    This research work demonstrates compositional engineering of an organic-inorganic hybrid nano-composites for modifying absolute threshold of humidity sensors. Vanadyl-2,9,16,23-tetraphenoxy-29H,31H-phthalocyanine (VOPcPhO), an organic semiconductor, doped with Titanium-dioxide nanoparticles (TiO2NPs) has been employed to fabricate humidity sensors. The morphology of the VOPcPhO:TiO2nano-composite films has been analyzed by atomic force microscopy (AFM) and field emission scanning electron microscopy (FESEM). The sensors have been examined over a wide range of relative humidity i.e. 20-99% RH. The sensor with TiO2(90nm) shows reduced sensitivity-threshold and improved linearity. The VOPcPhO:TiO2(90nm) nano-composite film is comprised of uniformly distributed voids which makes the surface more favorable for adsorption of moisture content from environment. The VOPcPhO:TiO2nano-composite based sensor demonstrates remarkable improvement in the sensing parameter when equated with VOPcPhO sensors.

    Abd Samad NA, Said I, Abdul Rahim A
    Stud Health Technol Inform, 2018;256:367-377.
    PMID: 30371497
    Access to our buildings relies to the accessibility of its external environment and the route taken. Developments and planning in urban areas has many several requirements and restrictions. Planning accessibility for Malaysian built environment is achievable by designing in compliance to the requirements enforced by authorities. Accessible design is commonly associated with providing facilities for Persons with Disabilities (PwDs), the issue that is often brought up is the inaccessibility of the external environment and lacking of seamless connectivity between buildings and the outdoor. The intention is to formulate accessibility strategies and work out planning process on how accessibility can be achieved. Universal Design will be the basis for the design and planning concept to accommodate all users to enjoy our urban built environment. It is notable that developed countries advances more in terms of implementing and enforcing accessibility measures via legislative and regulatory documents, government strategies and initiatives within its planning approach than the developing nations. The methodology will be looking into the establishment of strategies and measures of international and local planning policy, local and action plans of City of London as selected Local Authority to be analyzed its inclusive policy has been successfully implemented in their jurisdiction. The findings, discussions and result will be an outcome of generating a framework of accessibility strategies that is derived from interviews and government documents accordingly to targeted Malaysian urban areas focusing the City of Petaling Jaya and Putrajaya and how it can be improvised. Therefore, an interpretation of adopting accessibility planning strategies of developed country, to be adapted locally according to Malaysian legislation, culture and lifestyles.

    PMID: 3393924 DOI: 10.1016/0277-9536(88)90225-0
    In Sarawak, some tribes stay in communal longhouses whilst others live in villages of single dwellings. The present study looks into the question of whether there is an association between the prevalence of leprosy and tuberculosis with the quantum of social contact that occurs in these two types of settlement patterns. It was found that the prevalence of leprosy and tuberculosis is significantly higher among longhouse dwellers compared with single house dwellers. It was also noted that social groups tended to be larger and to persist for much longer among longhouse dwellers than among those in single dwellings. This lends support to the evidence that social contact in longhouses is more extensive and contributes towards a higher prevalence of leprosy and tuberculosis.

    PMID: 4095582
    This paper examines four drug rehabilitation systems in Malaysia from an organizational perspective. It focuses on authority structures in rehabilitation centres and their impact on rehabilitees' identities. The findings show that there are important differences between government-run and private centres in terms of administration and approach to therapy. Some policy implications are derived from a comparison of these systems.

    PMID: 4071118 DOI: 10.1016/0277-9536(85)90130-3
    A questionnaire on smoking habits was administered to 4106 Form IV school children in Kuala Lumpur. The period of survey was from 9 to 20 April 1984. 2099 boys and 2007 girls were studied and their mean age was 16.1 years. 32.8% of the students had been initiated to smoking and the mean age of initiation was 13.3 years. The prevalence of smoking was found to be 9.8% and the mean duration of smoking was 2.5 years. Most of the smokers and occasional smokers were boys. About 42% of the smokers wished to stop smoking and only 1% of the non-smokers intended to smoke in the future. The study recommended that health education programmes should be started earlier in school.
