Present research investigated the impact of executive dysfunction on academic performance among
students in their middle childhood. It was hypothesized that school teacher’s rating of executive
dysfunction in students can significantly predict their performance in Mathematics and Science
subjects. The study used primary data which was collected from public schools of Lahore. An
indigenized executive dysfunction inventory was constructed for this purpose and psychometric
properties were established. It was postulated that student’s performance in Science and Math will vary
based on their executive dysfunction and the results attested to this hypothesis. Demographic properties
were also evaluated through age, number of siblings, gender, family system, and mother profession.
Statistical findings revealed that higher level of executive dysfunction is associated with lower level of
science and math performance.
This study seeks to identify the relations of modernism and postmodernism in feminism by looking
deeply on the development of its definitions, waves of feminism and framework in its specific schools
of thought; liberal, classical Marxist, socialist and radical feminism. By adapting qualitative descriptive
study, this study covers mainly secondary data from English language sources, be it from books,
academic articles or any literatures pertaining to this topic, which obtained from various databases.
This study argues that modernism and postmodernism is the worldviews that become the essence of
feminism. By looking at the variations of how feminism is studied, e.g. definitions, waves and school
of thought, this study concluded that there are several points indicating the relations that exist between
modernism and postmodernism with feminism. Modernism can be seen in the relational approach of
the liberal, classical Marxist and socialist feminism in the first wave, which are more centered on
education, politics and economic participation. Meanwhile, the relation of postmodernism to feminism
is exampled in the deconstructing approach of the radical feminism that began from the second wave
shown in their individualist views on sex, sexuality, motherhood, childbirth, and language institution.
By identifying modernism and postmodernism as the essence of feminism, it can provide a thorough
understanding on how it relates to the construction and development of feminism itself. Besides that, it
also delineates pathway and limitation especially in providing critiques to feminism. Moreover, it also
helps to provide a new paradigm in looking at the feminism based on its essences that surpasses
traditional dimensions of feminism studies that usually separate feminism discourse into specific
variations.
Global prevalence of childhood overweight and obesity have increased drastically in the past years, including in Malaysia. School-based obesity intervention is important to promote healthy eating and behavioural change. Many obesity interventions have been conducted to combat childhood obesity; however, the sustainability of childhood obesity interventions are often overlooked. This study aimed to explore the factors that influenced sustainability of Juara Sihat intervention programme in Kuala Lumpur primary school. Face-to-face in-depth interviews were conducted with 26 children aged 12- 14 years old whom participated in the Juara Sihat intervention programme were purposively selected. Data was transcribed verbatim and analysed using thematic analysis. The main themes identified as motivators are (1) support from family, facilitators, school teachers, and friends; (2) physical activity and healthy eating practices after intervention; (3) self-awareness; (4) knowledge on food pyramid and healthy eating; and (5) home environment. While the barriers are (1) knowledge inconsistency; (2) own safety; (3) peers influence; (4) self-attitude; (5) boredom towards programme. The results showed that the main promoting factor for sustainability of Juara Sihat intervention programme is continued practice of physical activity and healthy eating, while the main barrier is knowledge inconsistency. Therefore, school-based obesity intervention programmes should consider these promoting and hindering factors that could influence the sustainability of intervention programmes. Future studies should consider those factors during program intervention planning especially when factors that influence implementation and sustainability are carefully considered and taken care of to ensure long-term success.
Histological observation has always been important in the study of sentinels. In this research, histological differences in the liver and kidney of two wild populations of Fejervarya limnocharis exposed to different environmental cadmium levels were observed. Liver and kidney samples from 30 rice frogs caught from reference site (Mae Pa) and contaminated site (Mae Tao) were sectioned and stained with Haemotoxylin and Eosin and then observed under light microscope. It was found that liver sections from frogs caught from Mae Tao had higher hepatic macro-melanophage count (MMC) (0.949 ± 0.267 cells/1000 μm2) as compared to those from Mae Pa (0.672 ± 0.299 cells/1000 μm2). Other observable histological features found in frog’s liver from Mae Tao include possible necrotic areas, cellular swellings and chromatin margination. The kidney sections from frogs caught from Mae Tao showed the presence of tumor-like cell aggregation and hemorrhage. However, the proportion of tumor-like cell aggregation and hemorrhage were not significantly different than were expected from random occurrences. The result of the histological study revealed that F. limnocharis caught from Mae Tao had higher hepatic MMC and higher prevalence of renal tumor-like aggregation and renal hemorrhage than the rice frogs caught from Mae Pa. Cellular swelling, possible necrotic area and possible apoptotic cell could also be observed in the liver of contaminated frogs.
Monosodium glutamate (MSG) is a flavour enhancer commonly used in processed food to increase palatability. Several studies have reported that chronic exposure of MSG causes renal fibrosis via oxidative stress mechanism. However, till date, the effects of low dose of MSG on the oxidative stress status and its histopathological observation of renal are still unclear. A total of 18 male Sprague Dawley rats (170 – 200 g) were divided randomly into three groups consisted of the control (received distilled water = 1 ml/kg), MSG 60 (received 60 mg/kg MSG) and MSG 120 (received 120 mg/kg MSG) groups. All of the substances were given via force-feed oral for 28 consecutive days. At the end of the study, all rats were sacrificed and the renal were isolated for biochemical and histological evaluation. The superoxide dismutase (SOD) activity and protein carbonyl (PC) level showed significantly increased (p < 0.05) in MSG 60 and MSG 120 group compared to the control group. However, no significant difference was found in glutathione (GSH) and malondialdehyde (MDA) level in all treated groups. The histology observation showed glomerulus shrinkage in MSG 60 and MSG 120 groups. In conclusion, these findings confirmed low dose of MSG-induced oxidative stress and histopathological changes on the renal of male Sprague-dawley rats. Accordingly, care must be taken on the intake of MSG in our daily basis.
Involvement of informal carer in post-stroke care is important to prevent development of secondary complications particularly among stroke survivors with severe disability. However, to date, evidence on the benefit of stroke care training and involving carer to assist in the care for this group of stroke survivors is still limited. In this study, we evaluated the outcome of a carer-assisted care program for stroke survivors with severe disability who live at home. Sixteen stroke survivors with severe disability and 16 primary carers participated in this pre-test post-test intervention study. Carers were trained using a stroke care module which was developed by a group of multidisciplinary researchers from Universiti Kebangsaan Malaysia, prior to implementing the daily care for 8 weeks. Outcome of care on stroke survivors was assessed in term of change in disability level and quality of life using Modified Barthel Index (MBI) and EuroQol health-state measure (EQ-5D and EQ-VAS), respectively. While outcome of stroke care training on carer was determined using Modified
Caregiver Strain Index (MCSI). Significant improvement is shown in the stroke survivors’ EQ-VAS component of EuroQol health state measure (average increase by 12%, t = 2.86, p = 0.01) following the care. Although not statistically significant (t = 0.97; p = 0.35), the mean score of MCSI reduced by 14%. No significant change was found in the MBI of the stroke survivors at completion of the program. Carer-assisted care is useful in improving quality of life of stroke survivors and can potentially reduce stress level among carers. Larger study may assist in establishing these preliminary findings.
Kajian terdahulu menunjukkan kualiti hidup dapat ditingkatkan melalui amalan keagamaan dan kerohanian. Hafazan al-Quran merupakan amalan keagamaan dan kerohanian yang memperkasa aspek mental dan fizikal. Namun, kajian saintifik yang mengaitkan hafazan al-Quran dengan kualiti hidup masih terhad terutamanya dalam konteks pelajar tahfiz. Maka, kajian ini bertujuan untuk mengenal pasti hubungan antara hafazan al-Quran dengan kualiti hidup dalam kalangan pelajar tahfiz di Selangor, Malaysia. Satu kajian keratan rentas telah dijalankan ke atas 116 pelajar dengan pensampelan rawak berstrata dari tiga buah sekolah tahfiz di Selangor. Pelajar tahfiz dikategorikan kepada tiga tahap hafazan berdasarkan jumlah juzuk yang telah dihafaz iaitu Tahap 1 (1-10 juzuk), Tahap 2 (11-20 juzuk) dan Tahap 3 (21-30 juzuk). Borang soal selidik telah digunakan untuk mendapatkan data sosiodemografi dan borang soal selidik Short Form-36 Quality of Life (SF-36) versi Bahasa Malaysia telah digunakan untuk menilai tahap kualiti hidup. Data telah dianalisa menggunakan SPSS versi 23.0. Hasil kajian mendapati wujud hubungan positif yang signifikan antara hafazan al-Quran dengan kesihatan fizikal (r = 0.300, p < 0.05) dan kesihatan mental (r = 0.194, p < 0.05). Ini jelas menunjukkan bahawa semakin banyak pelajar menghafaz al-Quran semakin tinggi tahap kualiti hidup mereka. Faktor yang mempengaruhi kesihatan mental dan fizikal adalah jumlah muka surat hafazan. Kesimpulannya, hafazan al-Quran berpotensi meningkatkan kualiti hidup serta kesihatan mental dan fizikal pelajar tahfiz.
In Malaysia, dengue fever is a common vector-borne disease. Most cases of dengue fever are reported in residential areas. Children are at high risk to be infected because they spend a lot of time around their housing area for outdoor activities. Such areas may have a high number of Aedes mosquitoes. As schools are equipped with infrastructure and medium for effective educational purposes, schools represent the most suitable facilities for learning and teaching process. A crosssectional study was conducted to determine the level of knowledge among students in Hulu Langat on Aedes mosquitoes, dengue fever, and Zika virus. The study also reported on the demographic factors which affected the knowledge level. Based on sample size calculation using G*Power v3.1 software, a total of 171 respondents were needed from the two primary schools involved in the study. Data collection was conducted using a pre-tested questionnaire that consisted of two main sections on demography and knowledge about Aedes mosquitoes, dengue fever and Zika virus. From the total score of 55, the mean knowledge score is 34.2 ± 8.38. Based on the median value of 36.0, about 50.9% of respondents had satisfactory knowledge. From the study, it was found that students from School A, students who had been watching video related to Aedes mosquito, and those with history of dengue infection among family members had a significantly better knowledge score (p < 0.01). In conclusion, knowledge about Aedes mosquitoes and related illnesses need to be enhanced through a comprehensive module and effective educational materials that can serve as a reliable source of information for primary school students.
Wood is one of the most common material found in homes and industrial fires, particularly in Malaysia. The abundance of different types of wood used to build structures, frames, furniture and others are important to take note as wood is a conducive material that can be used to initiate and propagate a fire, particularly in forensic fire cases. This study was conducted to provide the volatile chemical fingerprint of burnt Merbau (Intsia sp.) wood using gas chromatographymass spectrometry (GC-MS). The wood samples were prepared under two conditions; fully dried and partially dried. Six study replications of each condition were burnt outdoors and underwent an extraction process using activated carbon tablets. The tablets were incubated in an oven for 16 hours at 80ºC. Next, the tablets were desorbed in two different types of solvent; pentane and ethanol. The pentane- and ethanol-desorbed volatile products were then introduced into the GC-MS. Volatile organic compounds obtained across both conditions were in the range of volatile acids, aromatics and its derivatives, D-glucopyranose, phenolic derivatives and cycloalkane. The compounds emitted by fully and partially dried Merbau wood samples were similar, differing only in the absence of malonic acid and succinic acid in partially dried Merbau wood samples. Both solvents desorbed different types of volatile compounds. The burning behaviour of partially dried Merbau wood were different to those documented from fully dried Merbau wood and is attributed to the composition of wood rather than the dry or wet conditions.
Fibres are important trace evidence that can be found during the course of crime scene investigation. The identification and analysis of these fibres shed light as to the circumstances surrounding a particular crime. Identifying the factors that affect the transference of fibres under various environments are crucial in providing robust conclusions of a case per se, as highlighted in this work. Donor garments were made up of four different types of fibre; 100% cotton, 100% nylon, 100% polyester and 100% wool, that were used to observe the differences in the number of transferred fibres to the recipient garment (100% cotton) and vice versa with increasing contact times of 30, 60, 180, and 300 seconds respectively. To simulate contact between the donor garment worn by a suspect and the recipient garment worn by a victim in real-life situations, the donor garment was placed on top of the recipient garment which was laid on a piece of plywood. The numbers of transferred fibres, both from the donor to the recipient garment and from the recipient to the donor garment were observed and tested using microscopic examination, burning test, solubility test and dye extractability test. Results indicated that different types of garments transferred different number of fibres with increasing contact times, and the identification of the fibres are possible via the different tests applied in this work.
Certain public service pre-school teachers have been trained as vision screeners of children. However, there are no studies that assessed the knowledge and skills retention of these screeners. This study determines the level of knowledge retention among pre-school teachers who have been trained to perform vision screening on children. In 2013, 180 KEMAS pre-school teachers were recruited in a vision screening training which included both theory and practical sessions. Teachers were assessed through a theory test which comprised of 15 questions, firstly a category on the preparations needed for vision screening and secondly on the implementation of vision screening. They were then asked to conduct pre-school vision screening annually at their working premises. In 2016, 136 teachers who had been involved in the earlier program were recruited as subjects in this study. All these subjects answered the same set of theory test questions used in 2013. The Student’s t-test result indicated that the mean theory test scores obtained by the pre-school teachers in 2013 (84.3 ± 7.8) differed significantly with the mean scores obtained in 2016 (67.5 ± 11.3) (p < 0.001). The mean scores in 2013 for questions in the first and second categories were 4.5 and 4.4, decreasing to 4.2 and 3.7 in 2016. The knowledge level of pre-school teachers thus decreased with time and this effect was found significant after 3 years. There is therefore a need to conduct re-certification training, so that the screening conducted by these pre-school teachers remains effective and in accordance with established standards.
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.
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.
Introduction: The role of dietary intake on maternal glucose is uncertain. This study described the dietary charac- teristics of women with gestational diabetes mellitus (GDM) and examined the differences in dietary characteristics based on GDM diagnosis. Methods: This study recruited GDM women (n =45; age =31.1±5.1 years old) from health clinics in Seremban. Dietary intake, glycemic index (GI) and glycemic load (GL) were assessed using a semi-quanti- tative food frequency questionnaire (SFFQ) during first and second trimester of pregnancy. GDM diagnosis was made at 28 weeks gestation with the following cut-off for FPG 5.1 or 2hPG 7.8 mmol/L following oral glucose toler- ance test. Results: Women with GDM had a reasonable intake of protein and fat but consumed high-carbohydrate at second trimester and high-sugar diet at both trimesters. Fibre, iron and calcium from the food sources did not meet the recommended nutrient intakes for pregnancy. About 75.6% (n = 34) GDM women had high 2hPG (9.3 ± 1.5 mmol/L) with a normal FPG (4.7 ± 0.7 mmol/L). While dietary characteristics were not significantly different, women with a higher 2hPG tended to take a higher proportion of protein at first trimester and a higher dietary GI, serving of rice, and sugars and creamer at second trimester than high FPG. Conclusion: Suboptimal maternal nutrition in women with GDM are of particular concern. Dietary characteristics of women with high fasting and 2-hour glucose were comparable but not optimal. The needs of tailored nutritional intervention are evident in women known to be at high risk of GDM.
Health-Related Quality of Life (HRQOL) is an important data in managing Chronic Obstructive Pulmonary Disease (COPD). Therefore, it is essential to determine factors that associated with HRQOL and identify the gaps for future research. A systematic search using PubMed, Science Direct and Scopus was performed to discover factors that could impact HRQOL among COPD patients. Socio-demographic factors like age, gender, educational level, smoking status, income were found associated with HRQOL. Other factors included Body Mass Index (BMI), comorbidities, sleep quality and exercise capability also could influence HRQOL of COPD patients. Other than that, lung function, dyspnea and exacerbation also found closely related with HRQOL. However, future study is needed to explore more factors such as nutritional status. Besides that, the finding only focused on general population and very little infor- mation on elderly population.
Introduction: The objective of the study was to determine the factors associated with depressive symptoms (DS) among Malaysian Chinese elderly. Methods: This was a cross-sectional study using interviewer-administered ques- tionnaire conducted in a peri-urban area in Kajang, Selangor, Malaysia among 112 free-living residents aged 60 years and above, mean age 71.4±7.01 (60 to 89) years. Dietary food intakes and DS were assessed by 24-hour di- etary recall and 15-items Chinese Geriatric Depression Scale (C-GDS-15), respectively. Anthropometric parameters were obtained using standard procedures. Results: The prevalence of DS among the respondents was 36.6%. Most respondents reported physically inactive (96.5%), abdominal obesity (61.6%) and on average high selenium (81.9± 54.44) and low calcium intake (309 ± 173.36). According to MLR model, folate (β=-0.206, p=0.007), magnesium (β=-0.209, p=0.007) and iron (β=-0.202, p=0.009) intake were significant predictors of GDS score only if they were analyzed separately in the MLR model. However, after adjustment for gender, and other dietary nutrient intake, there were only good money satisfaction (OR=2.48, p=0.001) and dietary intake of iron (OR=1.385, p=0.050) showed significant associations with lower risk reporting DS. Conclusions: Prevalence of DS could be restricted by achieving a good economic satisfaction for the living and adequate intake of dietary iron, which with good overall nutrient will reflect a good nutritional status and health being.
Introduction: Women are vulnerable to food insecurity. This study aimed to determine the demographic factors, food security and mental health status among mothers in Mentakab, Pahang. Methods: This cross-sectional study was participated by 129 mothers aged 20 years to 59 years old. Mothers were interviewed to obtain information on demographic factors, food security status (Radimer/Cornell Hunger Scale) and mental health status (DASS-21). Chi-square and binary logistic regression were used to determine an association between factors and food security status. General linear model (GLM) was used to determine the difference in mental health score according to food security status group after controlling for covariates. Significance level was set at 0.05. Results: The mother’s mean age was 38.30 ± 9.70 years. Prevalence of food insecurity was 55.8%. About 39.5% of mothers were depressed, 24.0% were experienced anxiety and 16.3% of mothers were stressed. The mean depression and anxiety score were 4.11 ± 3.54 and 2.96 ± 3.19 respectively. The mean stress score was 3.91 ± 3.44. Low household income (p
Introduction: The aim of this study was to assess the validity and reproducibility of a food frequency questionnaire (FFQ) specifically developed for the assessment of riboflavin intake among Malaysian women in Selangor. Methods: The study was carried out in Universiti Putra Malaysia (UPM), which consisted of 204 healthy women (102 Chinese and 102 Malay) aged between 19 and 45 years. The FFQs were interviewer-administered, which were completed twice; at the beginning of the study (FFQ-1) and two weeks thereafter (FFQ-2). A two-day 24-hour dietary recall (24DR) was interviewer-administered as the standard criteria method. Data were analyzed using Wilcoxon signed ranks test, Spearman correlation coefficient (SCC), intra-class correlation coefficient (ICC) and Bland-Altman plots to determine the validity and reproducibility. Results: Median riboflavin intake derived from 24DRs was significantly higher than FFQ-2 (p
Introduction: This cross-sectional study determines factors associated with the rates of gestational weight gain (GWG) among women in the second and third trimester of pregnancy. Methods: A total of 180 pregnant women (29.2 ± 4.3 years old) attending the maternal and child health clinics in Batu Pahat district were enrolled in the present study be- tween January and February, 2015. Information regarding demographic characteristics, obstetrical history, physical activity, and calorie intake was assessed through direct interview. Anthropometric data were collected from medical records. GWG rates were determined based on 2009 IOM recommendations. Results: Of the 180 pregnant women, 37.2% were at their second trimester and 62.8% were at the third trimester of pregnancy. While 53.3% of them had excessive GWG rate, 28.9% have inadequate GWG rate. More than half of the women (56.7%) were normal weight, 21.1% overweight, 14.4% underweight, and 7.8% obese before pregnant. The total mean activity and energy intake of the pregnant women were 195.9±94.2 MET-hour/week and 2365±709 kcal/day, respectively. The multinomial logistic model indicates that women who were overweight or obese at pre-pregnancy were seven times more likely to have excessive GWG rate (OR = 7.44, 95% CI = 2.07-26.66) as compared to women who were pre-pregnancy normal weight. Conclusions: About four in every five of the pregnant women had their GWG rates outside the IOM recommendations. Women who were overweight/obese at pre-pregnancy were at-risk of having excessive GWG rate, which underlines the importance of targeting these women for pre-conception counselling on GWG.
Introduction: Night eating syndrome (NES) has been progressively drawing attention and becoming a global con- cern due to its clinical implications. However, the study related to NES was found to be scarce in Malaysia. As such, this study aimed to determine the risk factors of NES among Malaysian public university students. Methods: This cross-sectional study involved 270 participants (mean age: 20.9±1.4 years), who were selected randomly from three different course disciplines at a public university in Selangor, Malaysia. The data were collected using a self-admin- istered questionnaire on socio-demographic background, NES, depression, anxiety, stress, sleep quality, and disor- dered eating. Weight, height, and waist circumference of the participants were measured. Results: Results showed that 12.2% of the participants were engaged in NES. Binary logistic regression identified four significant risk factors of NES namely, being a male (AOR = 3.050, 95% CI = 1.129 – 8.238), persuading in a technical-stream course (AOR= 6.010, 95% CI = 2.057 – 17.555), being a stressful student (AOR = 3.580, 95% CI = 1.149 – 11.151), and having poor sleep quality (AOR = 4.664, 95% CI = 1.431 – 15.209). Conclusion: Early screening process should be con- ducted from time to time in which university students with potentially NES are able to receive necessary behavioural and cognitive therapy in order to recover.
