The paediatric rehabilitation service in Malaysia is shifting from the traditional child-focused approach to a family-centred
approach. At present, there is a lack of an evaluation tool to assess to the quality of paediatric rehabilitation services, and
whether the services are in line with the principles of the family-centred service. This study was undertaken to assess validity
and reliability of the Malay version of the Measure of Processes of Care 20-item (MPOC-20) questionnaire in evaluating
family-centered approach in children rehabilitation services in Kuala Lumpur. The original English version of the MPOC-
20 was translated into Malay language, before it was administered to 102 parents of children receiving rehabilitation
service at the Occupational Therapy Unit, UKM Medical Centre. The component structure of the MPOC-20 Malay version
was examined using principal component analysis with Varimax rotation to explore the factor structures after translation.
Cronbach’s alpha was calculated to determine the internal consistency reliability of the factors identified in the MPOC-20
Malay version. The resultant four-factor model explained 64 % of the variance in the Malay MPOC-20 responses. All four
factors were similar to the five factors described in the original MPOC-20. All the 20 items were retained, with relocation of
some items into a new factor. The Malay version of the MPOC-20 showed good internal consistency with Cronbach’s alpha
values ranging from 0.75 to 0.90. This study demonstrates that the Malay version of the MPOC-20 is valid and reliable,
and is suitable for evaluation of the quality of child rehabilitation services in the Malaysian context.
ABSTRACT
Clinacanthus nutans (C. nutans) leaf extracts have been widely used by cancer patients in Malaysia and local practice claims a cure to cancer. There were several studies done to determine the cytotoxicity potency of C. nutans extracts on various types of cells. However, there is still lacking on the knowledge regarding the combination effect of C. nutans with anticancer drugs. Thus, the study was carried out to determine the cytotoxicity potency of C. nutans extracts and paclitaxel (PTX) alone and, in combination on MDA-MB-231 cells. The cells were treated with 100% ethanol extract of C. nutans (CNE) and water extract of C. nutans (CNA), PTX and combination of both extracts and PTX for 72 hours and the cytotoxic activity was determined using SRB assay. Result showed that CNE had little cytotoxic activity, whereas CNA showed no cytotoxic activity on MDA-MB-231 cells. For combination treatment of C. nutans extracts and PTX, only CNE showed significant enhanced PTX-induced cytotoxicity (p < 0.05), meanwhile CNA inhibited PTX-induced cytotoxicity significantly (p < 0.05). As a conclusion, CNE was able to increase PTX potency to inhibit the viability of MDA-MB-231 cells.
Sex determination is one of the basic components in victim identification. This study aims to ascertain the sex of an individual from burnt teeth samples exposed at different temperature and time through nested polymerase chain reaction (PCR) on the amelogenin (AMEL) sex marker, to calculate the specificity and sensitivity, and to compare with previous relevant studies. A total of 17 teeth samples was subjected to burning at different temperatures ranging from 100°C to 500°C, at 2 to 10 minutes. The whole tooth was used for deoxyribonucleic acid (DNA) extraction by phenol-chloroform method. All samples were quantified for DNA concentration and then analyzed with nested PCR using two pairs of AMEL primer and results of sex typing were recorded. Out of 17 samples, genomic DNA extracted from 6 samples have concentrations ranging from 27.3 – 130.6 ng/μL. Nested PCR could amplify 16 samples for AMEL gene. Sex typing using AMEL gene showed 76.47% accuracy. Sensitivity of AMEL primer was increased from 6.67% to 63.64% using nested PCR technique; specificity of both external and internal primer was reported at 100%. Nested PCR of AMEL gene proved to be a suitable method for unequivocal determination of sex from degraded DNA samples.
Ficus deltoidea leaves were widely used as a tea beverages in Malaysia with no information of its mineral content. Hence the mineral content of two species of Ficus deltoidea leaves were investigated. The dried leaves of F. deltoidea var. angustifolia and F. deltoidea var. deltoidea were acid digested and mineral elements of Na, Mg, K, Ca, Mn, Cr, Fe and Zn were determined using ICP–MS. Magnesium, potassium, sodium, manganese, iron and zinc were found to be present in the leaves of F. deltoidea var. angustifolia and F. deltoidea var. deltoidea. Concentration of magnesium (1934 mg/L), manganese (58.37 mg/L), iron (6.89 mg/L) and zinc (1.77 mg/L) in F. deltoidea var. deltoidea species were significantly (P < 0.05) higher than in F. deltoidea var. angustifolia species with concentration of 317 mg/L, 29.62 mg/L, 4.55 mg/L and 1.26 mg/L for magnesium, manganese, iron and zinc respectively. Meanwhile, concentration of sodium in F. deltoidea var. deltoidea species (3.13 mg/L) was found to be significantly (P < 0.05) lower than the concentration in F. deltoidea var. angustifolia species (9.11 mg/L). The finding showed that the leaves of F. deltoidea var. deltoidea has higher nutritional value than the leaves of F. deltoidea var. angustifolia. Leaves of Ficus deltoidea especially the F. deltoidea var. deltoidea species contain high amount of magnesium, manganese and potassium. Therefore, tea made of this leaves can be served as a good source of minerals for human consumption.
Microbiological contaminations in the laboratories create not only diagnostic issues but also pose a major health risk to lab users. This study was conducted to determine the airborne microbial contamination in seven selected laboratories (KA, KP, PB, NA, BP, CR and MB) at a local public university in Malaysia and to assess the level of contamination on the contact surfaces of the studied laboratories. Two types of sampling methods were used in this study; passive air sampling and contact surface swab sampling. The total microbial counts were determined using Tryptone Soya agar (bacterial count) and Potato Dextrose agar (fungal count). Results showed that NA laboratory had the highest level of total microbial contamination (20.33 ± 3.35 CFU/cm3). Most laboratories had significantly higher (p < 0.05) air fungal contamination level compared to bacterial contaminations except for PB and NA laboratories. Significant differences were observed for airborne bacterial contamination readings between sampling time (during working hours vs after hours) for all laboratories except for BP and CR. Overall, bacterial contamination was the highest for incubator door handles’ samples from MB laboratory with an average reading of 93.00 ± 1.43 CFU/cm2 whereas the highest fungal contamination level was obtained from door knobs and work benches, both from CR laboratory with an average reading of 73.33 ± 6.67 CFU/cm2 and 73.33 ± 0.58 CFU/cm2 respectively. Findings from this study could assist in monitoring the efficacy of the existing laboratory management systems namely on the good laboratory practices including aseptic techniques, care for laboratory hygiene and cross-contamination control practices by the laboratory users to ensure that the microbiological contaminations in the laboratories are minimized.

Despite being becoming popular and heavily used in rehabilitation, the evidence on the effectiveness of Virtual reality-based therapy (VRBT) among persons with knee osteoarthritis (OA) remains limited. The aim of this study was to determine the effects of VRBT on walking endurance and quality of life of older persons with knee OA in comparison to conventional exercise therapy. This was a randomised controlled trial involving 44 participants (mean age and standard deviation = 66.32 ± 5.73 years) who received either a VRBT (experimental group, n = 22) or a conventional exercise therapy (control group, n = 22) for 45 minutes, twice per week for 12 weeks. The outcome of both therapies on walking endurance was measured using Six-Minute Walk Test (6 MWT), while quality of life was assessed using the Malay-version of Short Form-36 (SF-36). Analysis was done by ‘intention-to-treat’ approach, using Mixed Model ANOVA. A significant time-effect (p < 0.05), with large effect size between 0.43 and 0.54 were found for all outcomes following the therapies. An increase of 17% and 19% of 6 MWT scores were obtained in experimental and control group, respectively. Meanwhile, the scores for the physical and mental components of the SF-36 increased by 37.8% and 19.4% in the experimental group, and 45.7% and 20.6% in the control group. However, no significant group and interaction effects were found for all outcomes (p > 0.05). In conclusion, VRBT is comparable with conventional exercise therapy in improving walking endurance and quality of life of persons with knee OA, and can be used as a therapy option for this population.
Older adults who fall recurrently have sub-optimal physical performance especially muscle strength, mobility and balance. Recurrent falls lead to a heightened fear of falls. However, there is limited information regarding other domains of physical performance, namely flexibility and endurance. In addition, there is still limited knowledge pertaining fear of falls and physical activity levels among Malaysian community-dwelling older adults who are recurrent fallers. The aim of our study was to compare fear of falls, physical performance and physical activity levels among older adults with falls and recurrent falls. This cross- sectional study was carried out in two Malaysian urban districts. Physical performance was examined using Functional Fitness MOT (FFMOT). Modified Baecke Questionnaire and Activities-Specific Balance Confidence (ABC-6) Scale were administered to evaluate the level of daily physical activity and fear of falls respectively. A total of 35 older adults participated in this study, 20 fallers (mean age: 71.95±8.22) and 15 recurrent fallers (mean age: 76.73±8.82) respectively. Our study results showed that older adults with recurrent falls had significantly reduced lower extremity strength, dynamic balance, endurance, balance confidence in activities of daily living and physical activity levels compared to faller group (p < 0.05). Although flexibility and upper limb strength were not significantly different among fallers and recurrent fallers, overall improvement in physical performance should be targetted in falls prevention and management. This is vital to prevent further deterioration in physical performance among older adults with recurrent falls.
Kajian ini dijalankan untuk membentuk formula demi menganggar ketinggian tubuh badan dan menentukan jantina dengan menggunakan panjang dan lebar kaki. Seramai 150 orang subjek yang berumur 20-30 tahun diambil dari Universiti Kebangsaan Malaysia Kampus Kuala Lumpur (UKMKKL). Subjek tersebut adalah Melayu (45 lelaki dan 45 perempuan) dan Cina (30 lelaki dan 30 perempuan). Ketinggian, panjang dan lebar kaki diukur menggunakan alatan antropometrik dalam ukuran milimeter. Hasil statistik menunjukkan bahawa pelbagai ukuran kaki kanan dan kiri tidak mempunyai perbezaan yang signifikan (Panjang kaki/FL: t(298) = -0.235, p = 0.815; Lebar kaki/FW: t(298) = 0.932, p = 0.352). Perbezaan yang signifikan pada semua ukuran pula dapat dilihat pada jantina (Tinggi/S: t(148) = 12.550, p < 0.05; FL:t(148) = 11.692, p < 0.05; FW:t(148) = 8.321, p < 0.05). Bagi kaum, ketinggian tubuh badan kaum Cina adalah lebih tinggi berbanding kaum Melayu secara signifikan (t(148) = -3.103, p < 0.05) tetapi tiada perbezaan yang signifikan diperhatikan pada ukuran kaki (FL: t(148) = 0.002, p = 0.999; FW:t(148) = 1.362, p = 0.175). Korelasi yang paling tinggi telah ditunjukkan antara ketinggian tubuh badan dengan panjang kaki pada semua kumpulan. Analisis Regresi Garis Lurus dan Regresi Berganda telah digunakan untuk membentuk formula menganggar ketinggian tubuh badan. Walau bagaimanapun, didapati formula yang dibentuk dari Regresi Berganda adalah lebih tepat kerana kombinasi panjang dan lebar kaki menghasilkan korelasi koefisen yang lebih tinggi dalam semua formula (S = 585.298+(4.898xFL)-(1.453xFW), F(2,149 = 149.324, p < 0.01, R2 = 0.670). Formula untuk penentuan jantina juga telah dibina menggunakan Analisis Pokok Klasifikasi. Keputusan menunjukkan ketepatan untuk menentukan jantina seseorang adalah di antara 86.3-87.5% bagi perempuan dan 85.2-85.7% bagi lelaki dengan menggunakan panjang kaki manakala di antara 68.4-76.8% bagi perempuan dan 77.8-81.0% bagi lelaki dengan menggunakan lebar kaki.
The study was conducted to create specific formulae for stature estimation of adult male population in Malaysia based on measurements of femur, tibia and fibula lengths using radiographic method. A number of thirty two Malaysians from hospitals involved as subjects in this study. The subjects were Malays (14), Chinese (8) and Indians (10) from 25-45 years old. The standing height of the subject was recorded before femur, tibia and fibula were scanned with an x-ray
machine. The bones length was measured on the x-ray film in centimetres (cm) and analysed using Statistical Package for Social Sciences (SPSS) version 19.0 for Windows. The results showed a significant relationship (p < 0.05) between stature and measurements of length of femur, tibia and fibula. Stature of Malays and Indians were significant (p < 0.05) with measurements of length of femur, tibia and fibula but insignificant in Chinese. Simple Linear Regression Analysis was used to derive regression equation for single bone and Multiple Linear Regression Analysis was used to derive regression equation for combination of femur, tibia and fibula. Six formulae for stature estimation of adult male population in Malaysia were derived. The formulae consist of three formulae for single bone, a formulae for combination bones with unknown race, a formulae for combination bones of Malays population and a formulae for combination bones of Indians population. Formulae for combination bones had the highest correlation coefficient compared to the formula using a single bone. Standard error was found to be high in all the formulae due to small sample size. Extension for this study is essential to provide Malaysia with accurate formulae.
This paper investigate the effect of parents’ education background and family monthly income on the Intelligence Quotient
(IQ) of students with special needs in Kelantan, Malaysia. This cross-sectional method study was employed multistage
random sampling to obtain information drawn from 130 participants from 10 selected school in Kelantan, Malaysia.
Questionnaire was used to obtain parents’ education background, family monthly income and demographic variables.
Students IQ were assessed using Comprehensive Test for Non-Verbal Intelligence (CTONI 2nd Edition). Data analysis involve
independent sample t-test, one-way between group ANOVA, Pearson’s correlation and multiple linear regression. From
analysis of IQ score, 63.8% of the special needs students scored very poor IQ, 12.3% scored below average and only
1.5% score average IQ. Significant mean difference were revealed between age group (p = 0.002), parents’ education (p
= 0.018) and family monthly income (p < 0.05) on special needs students IQ. Post-hoc tukey shows significance between
parents who never went to school, went to secondary school (p = 0.037) and university/college (p = 0.021). In term of
family monthly income, significance difference were found between family with low and high monthly income (p < 0.05).
Family monthly income (r = 0.393, p < 0.01) showed positive moderate correlation on special needs students IQ. After
being forwarded by multiple linear regression, it was found that family monthly income (B = 3.605, p < 0.05) and age
group of special needs students (B = 0.879, p = 0.002) were significant predictor for IQ score and explained 22.5% of
the variance (R2
= 0.225, F (5,124) = 83.94, p < 0.05. Overally, majority of special needs students in current study have
very poor IQ score. Further explanation are discussed on the paper.
There is some evidence stated that mood states might influence cognitive functioning, such as episodic memory, working memory and creative problem solving. This study was conducted to evaluate the relationship between mood states and cognitive functioning among older adults with Mild Cognitive Impairment (MCI). This study involved 12 male and 37 female subjects from Klang Valley aged 60 year old and above. MCI was defined based on criteria proposed by Peterson. Cognitive functions of the subjects were accessed using Mini Mental State Examination (MMSE), Rey Auditory Verbal Learning Test (RAVLT), Digit Span, Digit Symbol Substituition Test (DSST) and Visual Reproduction; while mood states including tension, depression, anger, vigour, esteem related affect, fatigue and confusion were accessed using Profile of Mood States (POMS) questionnaire. Total positive subscales score, total negative subscales score and total mood disturbance (TMD) were also calculated. There were significant positive correlations between tension (r = 0.325, p = 0.30), vigour (r = 0.235, p = 0.036), esteem related affect (r = 0.316, p = 0.034) and total positive subscales score (r = 0.307, p = 0.040) with verbal episodic memory as measured using RAVLT fifth trial. In addition, positive correlations were also observed between vigour (r = 0.228, p = 0.035) and total positive subscales score (r = 0.237, p = 0.025) with DSST. After adjusted for confounding factors, subjects who scored higher in esteem related affect (Adjusted OR = 0.390, 95% CI [0.069-0.711], p = 0.019) and tension (Adjusted OR = 0.253, 95% CI [0.075-0.431], p = 0.007) had better verbal episodic memory. Subjects who have higher total positive subscales score were also had faster processing speed (OR = 0.856, 95% CI [0.099-1.614], p = 0.028). However after adjusted for confounding factors, the relationship was not significant (Adjusted OR = 0.383, 95% CI [-0.247-1.013], p = 2.226). Older adults with MCI who had a more positive mood tend to have a better short-term verbal memory and faster processing speed.
Sekolah tahfiz merupakan institusi yang mengkhususkan pendidikan kepada pelajar yang boleh menghafaz serta mengingati keseluruhan al-Quran. Aktiviti menghafaz al-Quran dengan teknik pengucapan berulang kali akan membantu meningkatkan keupayaan otak untuk memproses, mengingati maklumat dan membina memori. Kehadiran logam berat akan memberi kesan kepada sistem saraf serta mengganggu fungsi sistem saraf pusat dan periferi di mana akan seterusnya menyebabkan berlakunya kecelaan fungsi mental dan kognitif. Keupayaan untuk belajar, mengingati atau menghafaz, penggunaan bahasa dan untuk memahami sesuatu akan terganggu serta mengurangkan IQ dan perhatian. Kajian keratan rentas telah dilakukan bagi mengukur dan mengenal pasti hubungan di antara tahap logam berat, hafazan al-Quran dan tahap kecerdasan (IQ) dalam kalangan pelajar di sekolah tahfiz berbanding sekolah bukan tahfiz terpilih di Selangor. Kepekatan logam berat ditentukan melalui analisa sampel kuku dan rambut pelajar dengan menggunakan Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Ujian kecerdasan Wechsler Adult Intelligence Scale Edisi Kedua (WASI-II) digunakan untuk mengukur IQ pelajar. Borang soal selidik yang digunakan untuk mengumpulkan data demografik dianalisa menggunakan SPSS versi 23.0. Berdasarkan ujian korelasi Pearson yang dilakukan, terdapat korelasi negatif yang sangat lemah tetapi signifikan antara logam mangan dalam sampel rambut dengan tahap hafazan al-Quran (r = -0.178, p = 0.017). Selain itu, terdapat korelasi positif yang lemah tetapi signifikan antara IQ dengan tahap hafazan al-Quran (r = 0.375, p = < 0.001). Kesimpulannya, semakin tinggi kepekatan logam mangan akan menyebabkan penurunan tahap hafazan al-Quran serta apabila semakin tinggi tahap hafazan al-Quran akan menyebabkan tahap kecerdasan (IQ) juga semakin meningkat.
The aim of this study is to describe the development of neuropsychological research among epilepsy patients in Malaysia so far, the current trend and the focus of future research endeavour. The research in epilepsy grows concurrently with the interest in the field of neuropsychology in Malaysia. Beginning with the presurgical evaluation of epilepsy patients as part of the epilepsy protocols, research areas expanded further into neuropsychological profiling. The current trend in Malaysia is determining the factors influencing neuropsychological outcomes as well as the risk factors associated with low quality of life among epilepsy patients. The future neuropsychological research should emphasize on the effectiveness of neurorehabilitation of epilepsy patients as well as psychosocial and cultural issues particularly on social stigma and employability in line with the research priorities set by the Research Task Force of the ILAE Commission on Asian and Oceanian Affairs for people with epilepsy in Asia-Oceanic region.
Ulam is fresh traditional Malaysian vegetables which normally consumed in raw form or after a short blanching process.It contains high antioxidants and polyphenols. However, there is limited study about the relationship between ulam consumption and cognitive status. Thus, a cross sectional study was conducted to determine the relation with cognitive function among 132 middle-aged Malays adults (45-59 years old), ecruited by convenient sampling from low income residences in Klang Valley. Respondents were interviewed to obtain data on sociodemography, dietary intake and total ulam intake and also measured for anthropometric parameters at respective community centres. Cognitive status was measured using Digit Span (attention and working memory), Rey auditory verbal learning test (RAVLT) (verbal memory) and comprehensive trail making test (CTMT) (cognitive flexibility). The average ulam intake by the respondents was 15.1 ± 8.2g/day and the top five highest consumed ulam were petai (68.1%), pucuk paku (62.9%), ulam raja (56.8%), pegaga (54.6%) and kesum (44.7%).There was a significant correlation between ulam intake with Digit Span (r = 0.265, p = 0.006), total immediate recall of RAVLT (r = 0.427, p < 0.001) and CTMT (r = 0.257, p = 0.007). Analysis of multiple regression indicated that total ulam intake was a significant predictor for Digit Span (R2 = 0.152, p < 0.05), RAVLT (R2 = 0.335, p = 0.001) and CTMT (R2 = 0.310, p < 0.001). In conclusion, this study showed that ulam has the potential to protect against cognitive decline, however, randomized control trials should be conducted to determine the efficacy of the ulam as neuroprotective agent.

Keputusan kajian mendapati perbezaan yang signifikan bagi VA binokular jauh (t = 2.31, p < 0.05), VA binokular dekat (t = 0.89, p < 0.05) dan stereoakuiti (Z = -2.81, p < 0.01) antara subjek CI dengan subjek normal. Kesimpulan kajian menunjukkan subjek kumpulan CI mengalami penurunan prestasi penglihatan binokular jauh, prestasi penglihatan binokular dekat dan stereoakuiti yang signifikan lebih rendah berbanding kumpulan normal.
Low vision device (LVD) is prescribed to visually impaired (VI) schoolchildren to assist in their learning. One of the factors
that could influence the success of LVD use is the skills of using the devices. The objective of this study is to compare the
reading speed of VI schoolchildren before and after receiving LVD training by special school teachers. Twenty-two special
school teachers attended a series of workshop on the use of LVD. Twenty-two VI schoolchildren were recruited and paired
with teachers for training of LVD in the classroom (in-classroom training). A suitable LVD was prescribed by the researcher
to the schoolchildren before training commence. The total in-classroom training was 5 hours which is 1 hour/week. In
classroom training was based on a module that was developed at the beginning of the study and the teachers used a
checklist to monitor the schoolchildren’s progress. Reading speed in words per minute (wpm) was measured using UKM
near chart before and after completion of in-classroom training. All teachers successfully completed the in-classroom
training session. Results from One-way repeated measure ANOVA test showed reading speed improved significantly after
5 hours of in-classroom training, F(1.6,34.4)= 35.53, p < 0.001, partial ŋ² = 0.63. Reading speed of VI schoolchildren
have improved after completion of in-classroom training. This suggests that systematic training of LVD given by the special
school teachers assist VI schoolchildren to use their device effectively and thus, improved their reading speed.
A cross-sectional study was conducted among 200 Malays in Kuala Pilah, Tampin, Bahau, Gemencheh and Seremban towards food allergy in Negeri Sembilan. Questionnaire were used to determine demographic data, allergy symptom, practice and knowledge of respondents towards food allergy. Majority of the respondents that have food allergy were children 44% and shrimp was the most common allergen among children (25%). Family history is found to be associated with the age group and place of residents (p < 0.05). Common symptom that manisfested by respondents includes rashes (35%). Furthermore, the study showed that the respondents were concerned about their food allergy and 96% of the respondents reduced the intake of food that caused allergy. The level of knowledge related to food allergy was found to be associated with age group (p < 0.05). In conclusion, the study found that shrimp is the most common food allergy for all age group. Response towards food allergy is that they reduce the intake of food that cause allergy and the knowledge
towards food allergy is associated with age group. Therefore, early screening should be conducted to identify types of alergy so that appropriate treatment can be given to the patients. Health education on allergy is also important to improve knowledge and patients’ compliance towards treatment.

Occupational injury is an issue that needs to be considered in reducing the problems of disability and death in the
workplace. Healthy and high-productivity workers are one of the important factors that are important to the economic
growth of a country. This study aims to identify the trend of disability for employees covered by the Employment Injury
Scheme under the Social Security Organization Malaysia (SOCSO) for the years 2009-2013. Based on the descriptive
analysis, 80% of the total numbers of workers who suffer injury or death in the workplace are male employees. In
addition, workers aged 25 and above are more prone to injury and death associated with work. The results showed that
socio-demographic factors such as gender and age, as well as level of disability are several important factors that need
to be considered in identifying the trend of disability among employees.
