Polyethylene versus cotton cap as an adjunct to body wrap in preterm infants

Shafie H, Syed Zakaria SZ, Adli A, Shareena I, Rohana J

Pediatr Int, 2017 Jul;59(7):776-780.
PMID: 28370991 DOI: 10.1111/ped.13285

BACKGROUND: Occlusive body wrap using polyethylene plastic applied immediately after birth had been shown to reduce hypothermia among preterm infants. Various adjunct methods have been studied in an attempt to further reduce the incidence of hypothermia. This study was conducted to determine whether polyethylene cap is more effective than cotton cap as an adjunct to polyethylene occlusive body wrap in reducing hypothermia in preterm infants.
METHODS: The subjects consisted of preterm infants 24-34 weeks' gestation born at Universiti Kebangsaan Malaysia Medical Centre. Infants were randomly assigned to NeoCap or control groups. Infants in both groups were wrapped in polyethylene sheets from the neck downwards immediately after birth without prior drying. Infants in the control group had their heads dried and subsequently covered with cotton caps while infants in the NeoCap group had polyethylene caps put on without drying. Axillary temperature was measured on admission to the neonatal intensive care unit (NICU), and after having been stabilized in the incubator.
RESULTS: Among the 80 infants recruited, admission hypothermia (axillary temperature <36.5°C) was present in 37 (92.5%) and in 40 (100%) in the NeoCap and control groups, respectively. There was no significant difference in mean temperature on NICU admission between the two groups (35.3 vs 35.1°C, P = 0.36). Mean post-stabilization temperature, however, was significantly higher in the NeoCap group (36.0 vs 35.5°C, P = 0.01).
CONCLUSION: Combined use of polyethylene body wrap and polyethylene cap was associated with a significantly higher mean post-stabilization temperature compared with polyethylene body wrap and cotton cap.

The Silver Reed Model LK150 knitting machine is a home knitting machine which is
extremely lightweight and compact, making it preferable by most home knitters.
There are various knitwears with interesting patterns can be made using this model. In
the field of garments manufacturing by using flatbed knitting machines, it is
important to understand the physical properties of fabric so that their impact on
dimensional changes can be predicted to produce the most suitable end use. The
samples were produced by using a blended bamboo/cotton yarn, with a composition
of 30% cotton and 70% bamboo. The main objectives of this study are to to evaluate
the physical properties of single jersey fabric knitted on home knitting machine by
using different stitch dials and to relate the physical properties with different stitch
lengths. Then, all tests were conducted to compare the physical properties of samples
between three different stitch dials and the effects of before and after washing. The
physical properties measured in this research were stitch length, stitch density, weight,
thickness, absorbency and shrinkage. The result indicated that the longer the stitch
length, the higher the percentage of the water impact penetration. Meanwhile, there
was a slight reduction on the density, thickness and fabric weight. In addition, the
result after three times washing showed that the samples only had slight changes in
density, thickness, weight and stitch length, but has significant changes on the water
impact penetration.

Personal antimosquito measures plus proguanil for malaria prophylaxis in southern Malaysia

Henderson A, Rixom JA

Trans R Soc Trop Med Hyg, 1986;80(6):981-2.
PMID: 3603647

During the early months of 1985 and 1986, 408 non-immune British soldiers undertook training in the jungles north of Kota Tinggi, in southern Malaysia. In this geographical location, where malaria transmission is now light, a combination of strict personal antimosquito measures plus proguanil 200 mg daily produced effective, safe protection, with only a single case of vivax malaria occurring. Given the limited malaria risk, however, the results of this study should be extrapolated only with caution to other areas of Malaysia.

Hoong-Pin Lee, Abdullah Zawawi Awang, Wahid Omar

Pertanika Journal of Science & Technology, 2017;25(105):235-244.
MyJurnal

High strength concrete (HSC) has lower ductility, but higher in strength compared to normal strength concretes. The strength and ductility of HSC can be improved by applying external confinement, such as steel strapping tensioning technique (SSTT). However, SSTT was literately reported effective in confining circular specimens, but the effectiveness of SSTT on square cross section specimens are yet well investigated. This study focuses on HSC square cross section specimens with different corner ratio, which were right angle and rounded corner. In addition, the effect of different number of layer of steel straps confining around the specimens under optimum lateral pre-tensioning stress also been investigated. The number of layers was fixed to two layers and four layers. Fifteen HSC specimens with dimension of 88 mm x 88 mm x 200 mm, which consist of three unconfined specimens, six right angle specimens, and six rounded corner specimens were prepared and tested monotonically to failure. The experimental results show that the strength and ductility of HSC improved significantly by using rounded corner confined specimens and higher number of layer of confinements. This is due to more uniform confining pressure was exerted on entire surface of rounded corner confined specimens. The strength and ductility of the specimens can be improved up to 53.7% and 207.5% respectively.

Perceptions on radioprotective garment usage and underlying reasons for non-adherence among medical radiation workers from public hospitals in a middle-income Asian setting: A qualitative exploration

Mohd Ridzwan SF, Bhoo-Pathy N, Isahak M, Wee LH

Heliyon, 2019 Sep;5(9):e02478.
PMID: 31687573 DOI: 10.1016/j.heliyon.2019.e02478

Background: Radioprotective garments protect medical radiation workers from exposure to radiation at workplace. However, previous studies have found poor adherence to the use of radioprotective garments.
Objectives: We explored the perceptions and practices related to the use of radioprotective garments among medical radiation workers in public hospitals, and sought to understand the reasons for non-adherence.
Design and setting: A qualitative approach was applied by conducting face-to-face in-depth interviews with 18 medical radiation workers from three university hospitals using a semi-structured interview guide.
Results: Five themes emerged with respect to perceptions on the use of radioprotective garments: (i) the dilemmas in practising radiation protection, (ii) indication of workers' credibility, (iii) physical appearance of radioprotective garments, (iv) practicality of radioprotective garment use, and (v) impact on workflow. Actual lack of radioprotective garment use was attributed to inadequate number of thyroid shield and other garments, radioprotective garments' unsightly appearance including being dirty and defective, impracticality of using radioprotective garments for some nuclear medicine procedures, disruption of workflow because of workers' limited movements, attitudes of workers, and organisational influences.
Conclusion: Medical radiation workers demonstrated a definitive practice of using radioprotective aprons, but often neglected to use thyroid shields and other garments. Availability and hygiene are reported as the core issues, while unclear guidelines on practical use of radioprotective garments appear to lead to confusion among medical radiation workers. To the best of our knowledge, this is the first qualitative study of its kind from a middle-income Asian setting.

On the Choice of the Prior Distribution in the Bayesian Analysis for the Evaluation of Mini-Roundabouts as a Road Safety Measure

Kamarulzaman bin Ibrahim

Sains Malaysiana, 1996;25.

An integral art of the Bayesian approach which is not present in the classical approach is the prior distribution. Different researchers may have different level of prior knowledge regarding the parameter of interest before seeing the data. Sometimes different prior distributions can result in different decisions, as such investigations have to be careful in making the choice of the prior distribution. In this paper, we compare results from the Bayesian analyses based on three possible choices of the prior distributions, which are uniform prior, lognormal prior and an improper prior, in the evaluation of the effectiveness of mini-roundabouts. Data from five before and after studies into the effect of mini-roundabouts when replacing priority junctions are used. The effects of the different prior distributions are distinguishable from the analysis of an anamolous 'desk-drawer' study. The uniform and improper prior pull the estimated treatment effect away from one more than the lognormal prior. The results based on lognormal prior depict a less worst scenario of the ineffectiveness of mini-roundabouts and this may correspond to the deficiency in engineering design at only a few sites. Consequently, it is more appropriate to use the lognormal prior in the analysis of mini-roundabouts as a road safety measure.
Satu ciri yang penting dalam kaedah Bayesian yang tidak ada dalam kaedah klasik ialah taburan prior. Sebelum melihat data, mungkin setiap penyelidik mempunyai tahap pengetahuan prior yang berbeza berkenaan sesuatu parameter yang ingin dikaji. Kadang-kala taburan prior yang berlainan boleh menghasilkan keputusan yang berlainan. Oleh itu, pengkaji perlu berhati-hati dalam memilih taburan prior. Dalam kertas-kerja ini, kami bandingkan keputusan dari analisis Bayesian berdasarkan tiga pilihan taburan prior yang menasabah iaitu prior seragam, prior lognormal dan prior tak wajar untuk menilai keberkesanan bulatan mini. Data dari kajian-kajian sebelum dan selepas terhadap kesan mengantikan persimpangan dengan bulatan mini digunakan. Kesan taburan prior yang berlainan dapat dibezakan berasaskan keputusan analisis terhadap satu kajian 'laci-meja' yang ganjil. Prior seragam dan prior fak wajar felah menyebabkan anggaran nilai kesan rawatan melebihi satu lebih dari prior lognormal. Keputusan berasaskan prior lognormal ini menunjukkan senario yang kurang teruk tentang kurang berkesannya bulatan mini dan mungkin ini boleh dikaitkan dengan rekabentuk kejuruteraan yang tidak baik di beberapa tempat sahaja. Dengan itu, prior lognormal adalah lebih sesuai digunakan untuk menilai bulatan mini sebagai langkah keselamatan jalanraya.

Fulltext Occupationally Acquired Plasmodium knowlesi Malaria in Brunei Darussalam

Koh GJ, Ismail PK, Koh D

Saf Health Work, 2019 Mar;10(1):122-124.
PMID: 30949391 DOI: 10.1016/j.shaw.2018.09.002

Simian malaria is a zoonotic disease caused by Plasmodium knowlesi infection. The common natural reservoir of the parasite is the macaque monkey and the vector is the Anopheles mosquito. Human cases of P. knowlesi infection has been reported in all South East Asian countries in the last decade, and it is currently the most common type of malaria seen in Malaysia and Brunei. Between 2007-2017, 73 cases of P. knowlesi infection were notified and confirmed to the Ministry of Health in Brunei. Of these, 15 cases (21%) were documented as work-related, and 28 other cases (38%) were classified as probably related to work (due to incomplete history). The occupations of those with probable and confirmed work related infections were border patrol officers, Armed Forces and security personnel, Department of Forestry officers, boatmen and researchers. The remaining cases classified as most likely not related to work were possibly acquired via peri-domestic transmission. The risk of this zoonotic infection extends to tourists and overseas visitors who have to travel to the jungle in the course of their work. It can be minimised with the recommended use of prophylaxis for those going on duty into the jungles, application of mosquito/insect repellants, and use of repellant impregnated uniforms and bed nets in jungle camp sites.

New Zealand Malayan war veterans' exposure to dibutylphthalate is associated with an increased incidence of cryptorchidism, hypospadias and breast cancer in their children

Carran M, Shaw IC

N Z Med J, 2012;125(1358):52-63.
PMID: 22864157

It is well known that the endocrine-disrupting chemical (EDC) dibutylphthalate (DBP) inhibits testosterone synthesis and can lead to feminisation in male laboratory animals. Moreover, it has long been speculated that human exposure would result in the similar effects, but this is difficult to study because specific human exposure cohorts are rare. We report increases in the incidences of hypospadias (p<0.05), cryptorchidism (p<0.05) and breast cancer (p<0.05) in the children of New Zealand soldiers who served in Malaya (1948-1960) and were exposed to DBP applied daily to their clothing as an acaricide to prevent tick-transmitted bush typhus. In addition, we modelled absorption of DBP from the soldiers' clothing and using published data for skin absorption, and calculated a large theoretical absorbed dose of 64 mg/kg body weight/day which is similar to DBP's lowest observed adverse effect level (LOAEL) of 50 mg/kg body weight/day and thus indicates a biological effect is possible. This is the first report of a multigenerational developmental effect following DBP exposure in human males.

National paediatric core curriculum to national undergraduate medical curriculum

Alam Sher Malik, Rukhsana Hussain Malik

Malaysian Journal of Paediatrics and Child Health, 2005;14(1):5-13.
MyJurnal

The medical education should be tailored to deal with the diseases the physician is most likely to see.' With expectations that all the graduates from Malaysian Medical Schools should be able to serve anywhere in the country, the need for a national curriculum is self-evident. It may be argued that the public must have confidence in the competence of the practitioners they depend upon irrespective of the school from which they had graduated. In smaller countries in which health needs are uniform the graduates of any school should have been trained to meet those needs. In larger countries and those with geographic diversities and distances (e.g. Malaysia), the curriculum should cover the commonly encountered diverse ailments. If not dealt with care, we may end up with huge load of ever expanding, unmanageable curriculum.

Fulltext Mondor’s disease

Siti Kamariah, C.M.

International Medical Journal Malaysia, 2011;10(1):47-49.
MyJurnal

A Mondor’s disease is a rare, benign and self-limiting condition. It is due to thrombophlebitis of the superficial veins of the breast and chest wall. It usually occurs in middle-aged women who present with a palpable cordlike structure, often painful in the acute phase. The aetiology is unknown, and may be related to trauma, surgery, infection or tight clothing. The finding of a superficial vessel seen as a linear opacity on mammography and a tubular structure on ultrasound is typical. An intra-luminal thrombus may be seen on ultrasound, and there may be absent flow on Doppler imaging. Conservative treatment is usually instituted, although surgery may be indicated in certain circumstances.

Fulltext Microclimate inside a tropical greenhouse equipped with evaporative cooling pads

Diyana Jamaludin, Desa Ahmad, Rezuwan Kamaruddin, Hawa Z. E. Jaafar

Pertanika Journal of Science & Technology, 2014;22(1):255-271.
MyJurnal

Tropical greenhouses require active evaporative cooling system such as pad-and-fan to ensure a suitable microclimate for crop production. Excess heat causes indoor temperature to become hotter than desired resulting in detrimental effects to crop growth and production. Solar radiation intensity and outside temperature affect temperature and relative humidity level inside a greenhouse, while wide gradients in temperature and relative humidity can cause problems related to crop growth and production uniformity. A 300 m2 greenhouse, equipped with evaporative pad and four exhaust fans at each end walls, was used in the study. Horizontal and vertical profiles of the temperature and relative humidity inside the greenhouse were investigated. Results showed that temperature increased from evaporative pad area to exhaust fans area in a horizontal plane, while relative humidity showed an inverse pattern from temperature. In the vertical plane, temperature increased, while relative humidity decreased from lower level to the upper level. ANOVA results showed that in overall, temperature and relative humidity inside the greenhouse were uniform as there was no significant difference at 95% confidence interval. Thus, it was concluded that greenhouse cooling system by evaporative pad and exhaust fans are suitable for application in a tropical country such as Malaysia.

Wan, Ngeow Yen, Chin, Khaw Pei, Che Su Mt. Saad

Pertanika Journal of Science & Technology, 2011;19(1):171-176.
MyJurnal

Reclaimed rubber from rejected natural rubber (NR) latex gloves (r-NRG) was evaluated as partial
replacement for Standard Malaysian Rubber (SMR) 20 in producing microcellular rubber. In the study, the amount of reclaimed rubber varied from 20 pphr to 95 pphr for the purpose of cost reduction, environmental interest and as processing aids in reducing internal porosity, swells and to minimize shrinkage and air-trapped problems in producing microcellular rubber. A typical formulation in making microcellular rubber slab was developed and two-roll mill was used for compounding. The cure characteristics and mechanical properties, such as density, hardness, tensile strength, and elongation at break, were evaluated. Scorch time and cure rate index performed marginal decreased with increasing of r-NRG content. 95 pphr r-NRG blends showed a consequential drop in hardness. Both tensile properties and elongation at break decreased as the r-NRG content was increased.

Fulltext Metal diagenesis and transport in coastal sediments around Penang Island , Malaysia

Khalik Wood, A., Zaharudin Ahmad, Noor Azhar Md. Shazili, Rosnan Yaakob, Carpenter, Roy

Journal of Nuclear and Related Technologies, 2004;2004(1):1-22.
MyJurnal

Spatial and temporal variations in concentrations of several metals and isotopes in sediment cores from around Penang Island, an area with economically important biological resources off the northwest coast of peninsular Malaysia, are reported. Because of a typical, monazite rich mineralogy in surrounding drainage basins, sedimentary metal enrichment factors relative to global average materials, enrichment factors (EFs) of ˃1.0 do not always indicate significant anthropogenic metal inputs. Because of extensive metal solubilization in the hot, organic carbon rich area, EFs of < 1.0 may be observed for several metals despite significant anthropogenic contributions. Comparison of metal-Al relationships in Penang area surface sediments with those in nearby and presumed uncontaminated Strait of Malacca sediments more accurately correct for atypical regional solubilization and mineralogical effects than comparison to global average materials. Such comparisons show concentrations of Cd, Cu, Pb, Ni, Cr, As, Sb, Zn and V have changed by less than a factor of two by anthropogenic discharges. Sedimentary concentration profiles of Pb, Zn and Cu, ratioed to Sc to normalize for variations in grain size and mineralogy, have subsurface maxima suggestive of modest and recently reduced anthropogenic inputs. Mn, U, As and Sb have Sc-normalized concentration profiles clearly affected by diagenetic processes. Sc-normalized profiles of Cr, Th, Ce and Sm show only small changes with depth, confirming insignificant anthropogenic inputs and undetectable postdepositional diagenetic mobility.
Excess ²¹⁰Pb activities and fluxes in Penang area sediments are limited by supply of this radionuclide, in contrast to sediments of both the northwestern U.S.A. and Amazon continental shelves, where they are limited by particle scavenging reactions.²¹⁰Pb activities in sediments of
the shallow, dynamic Penang area often show erratic or unconvincing changes with depth that
cannot be reliably modeled by assuming steady state, constant deposition rate of particles of
uniform chemistry, mineralogy and initial unsupported ²¹⁰Pb, and that mixing is limited to a
recognizable surface layer and resemble a diffusive process.

Fulltext Major epidemiological factors associated with leptospirosis in Malaysia

Garba B, Bahaman AR, Bejo SK, Zakaria Z, Mutalib AR, Bande F

Acta Trop, 2018 Feb;178:242-247.
PMID: 29217379 DOI: 10.1016/j.actatropica.2017.12.010

INTRODUCTION: Leptospirosis is a zoonotic disease caused by a diverse pathogenic leptospira species and serovars. The disease is transmitted directly following contact with infected urine and other body fluids or indirectly after contact with water or soil contaminated with infected urine.
OBJECTIVES: While a wide range of domestic and wild animals are known to be reservoirs of the disease, occupation, international travel and recreation are beginning to assume a center stage in the transmission of the disease. The objective of this study is to review available literatures to determine the extent to which these aforementioned risk factors aid the transmission, increase incidence and outbreak of leptospirosis in Malaysia.
STUDY DESIGN: The review was conducted based on prevalence, incidence, and outbreak cases of leptospirosis among human and susceptible animals predisposed to several of the risk factors identified in Malaysia.
METHODS: Literature searchers and reviews were conducted based on articles published in citation index journals, Malaysian ministry of health reports, periodicals as well as reliable newspapers articles and online media platforms. In each case, the newspapers and online media reports were supported by press briefings by officials of the ministry of health and other agencies responsible.
RESULTS: The disease is endemic in Malaysia, and this was attributed to the large number of reservoir animals, suitable humid and moist environment for proliferation as well as abundant forest resources. Over 30 different serovars have been detected in Malaysia in different domestic and wild animal species. This, in addition to the frequency of flooding which has increased in recent years, and has helped increase the risk of human exposure. Occupation, recreation, flooding and rodent population were all identified as an important source and cause of the disease within the study population.
CONCLUSION: There is an urgent need for the government and other stakeholders to intensify efforts to control the spread of the disease, especially as it greatly affect human health and the tourism industry which is an important component of the Malaysian economy. The risk of infection can be minimized by creating awareness on the source and mode of transmission of the disease, including the use of protective clothing and avoiding swimming in contaminated waters. Moreover, improved diagnostics can also help reduce the suffering and mortalities that follow infection after exposure to infection source.

Is the hijab protective? An investigation of body image and related constructs among British Muslim women

Swami V, Miah J, Noorani N, Taylor D

Br J Psychol, 2014 Aug;105(3):352-63.
PMID: 25040005 DOI: 10.1111/bjop.12045

Previous studies have reported equivocal findings concerning the impact of wearing a hijab, or Islamic head- and body-cover, on Muslim women's body image. Here, we sought to examine that impact using a larger sample of Muslim women than has been relied upon and a wider range of body image measures. A total of 587 British Muslim women completed a battery of scales assessing their frequency and conservativeness of hijab use, body image variables, attitudes towards the media and beauty ideals, importance of appearance, and religiosity. Preliminary results indicated that 218 women never used the hijab and 369 women used some form of the hijab at least rarely. Controlling for religiosity, women who wore the hijab had more positive body image, lower internalization of media messages about beauty standards, and placed less importance on appearance than women who did not wear the hijab. Among women who wore the hijab, hijab use significantly predicted weight discrepancy and body appreciation over and above religiosity. These results are discussed in terms of the possible protective impact among British Muslim women of wearing the hijab.

Med J Malaysia, 2020 01;75(1):78-79.
PMID: 32008026

Accidental swallowing of objects commonly occurs among children and most of the objects pass through the gastrointestinal tract and out with the stool without any complications. However, recent reports have shown that there is an increasing occurrence of accidental ingestion of hijab pins among young hijab-wearing Muslim women or "hijabi". We highlight one such case, in which a young lady accidentally swallowed a pin that she was holding between her lips while she was styling her hijab. The pin was not successfully retrieved via endoscopy but was fortunately excreted spontaneously without any serious complications.

Fulltext Influence of vitamin D binding protein polymorphism, demographics and lifestyle factors on vitamin D status of healthy Malaysian pregnant women

Lee SS, Ling KH, Tusimin M, Subramaniam R, Rahim KF, Loh SP

BMC Pregnancy Childbirth, 2020 Nov 23;20(1):714.
PMID: 33228578 DOI: 10.1186/s12884-020-03397-7

BACKGROUND: Vitamin D deficiency (VDD) has been related to vitamin D binding protein (GC) gene polymorphism, demographics and lifestyle factors in different populations. However, previous studies only focused on demographic and lifestyle factors or genetic factors alone. Therefore, this cross-sectional study aimed to assess the association between GC gene polymorphism, demographics and lifestyle factors with VDD among Malaysian pregnant women.
METHOD: Information on demographic characteristics, dietary vitamin D intake from supplement and food, time spent outdoors, skin type and clothing were collected using a questionnaire. Plasma total 25-hydroxyvitamin D (25OHD) levels were measured using an Ultra-High-Performance Liquid Chromatography (UHPLC). Maternal GC single nucleotide polymorphisms (SNPs) (rs4588 and rs7041) were determined using restriction fragment length polymorphism (RFLP) technique.
RESULTS: Results showed that 50.2% of pregnant women were vitamin D deficient (25OHD

Fulltext High prevalence of methicillin-resistant Staphylococcus aureus (MRSA) on doctors' neckties

Koh KC, Husni S, Tan JE, Tan CW, Kunaseelan S, Nuriah S, et al.

Med J Malaysia, 2009 Sep;64(3):233-5.
PMID: 20527275 MyJurnal

We set out to investigate whether neckties worn by doctors are more likely to be contaminated with Methicillin resistant Staphylococcus aureus (MRSA) compared to neckties worn by preclinical medical undergraduates who have never been exposed to a hospital environment. We discovered that more than half (52%) of neckties worn by doctors were contaminated with Staphylococcus and out of these, 62% of them were identified as MRSA. In contrast, none of the student's ties were contaminated with MRSA. Due to the high prevalence of staphylococcus detected on doctors' neckties, we recommend that health care workers do not wear neckties.

Heat transfer at a stretching/shrinking surface beneath an external uniform shear flow with a convective boundary condition

Fazlian Aman, Anuar Ishak, Pop J

Sains Malaysiana, 2011;40:1369-1374.

The heat transfer behaviour of a viscous fluid over a stretching/shrinking sheet driven by a uniform shear in the far field with a convective surface boundary condition is studied. The boundary layer equations governing the flow are reduced to ordinary differential equations using a similarity transformation. Using a numerical technique, these equations are then solved to obtain the temperature distributions and the heat transfer rate at the surface for various values of Prandtl number, stretching/shrinking parameter and convective parameter. Dual solutions are found to exist for the shrinking case, whereas for the stretching case, the solution is unique.
