    Dengue is a mosquito-borne viral disease endemic in many countries in the tropics and sub-tropics. The disease affects mainly children, but in recent years it is becoming more of an adult disease. Malaysia experienced a large dengue outbreak in 2006 to 2007, involving mostly adults, with a high number of deaths.

  2. Fulltext Infrequent breakfast consumption is associated with higher body adiposity and abdominal obesity in Malaysian school-aged adolescents
    Nurul-Fadhilah A, Teo PS, Huybrechts I, Foo LH
    PLoS One, 2013;8(3):e59297.
    PMID: 23520556 DOI: 10.1371/journal.pone.0059297
    Unhealthy dietary pattern increases the risk of obesity and metabolic disorders in growing children and adolescents. However, the way the habitual pattern of breakfast consumption influences body composition and risk of obesity in adolescents is not well defined. Thus, the aim of the present study was to assess any associations between breakfast consumption practices and body composition profiles in 236 apparently healthy adolescents aged 12 to 19 years. A self-administered questionnaire on dietary behaviour and lifestyle practices and a dietary food frequency questionnaire were used. Body composition and adiposity indices were determined using standard anthropometric measurement protocols and dual energy χ-ray absorptiometry (DXA). Mean age of the participants was 15.3±1.9 years. The majority of participants (71.2%) fell in the normal body mass index (BMI) ranges. Breakfast consumption patterns showed that only half of the participants (50%) were consuming breakfast daily. Gender-specific multivariate analyses (ANCOVA) showed that in both boys and girls, those eating breakfast at least 5 times a week had significantly lower body weight, body mass index (BMI), BMI z-scores, waist circumference, body fat mass and percent body fat (%BF) compared to infrequent breakfast eaters, after adjustment for age, household income, pubertal status, eating-out and snacking practices, daily energy intakes, and daily physical activity levels. The present findings indicate that infrequent breakfast consumption is associated with higher body adiposity and abdominal obesity. Therefore, daily breakfast consumption with healthy food choices should be encouraged in growing children and adolescents to prevent adiposity during these critical years of growth.

    PMID: 22799379
    BACKGROUND: Breast cancer is the most common cancer among women in Malaysia. Barriers for practicing breast self examination (BSE) await exploration.

    OBJECTIVE: To assess the practice of BSE and its correlated factors and particularly barriers amongst urban women in Malaysia.

    METHODS: This cross-sectional study was conducted with 222 Malaysian women using a self-administered questionnaire.

    RESULTS: The mean (SD) age was 28.5 (±9.2) years, 59.0% were university graduates. Of the total, 81.1% were aware of breast cancer and 55% practiced BSE. Amongst 45% of respondents who did not practice BSE, 79.8% did not know how to do it, 60.6% feared being diagnosed with breast cancer, 59.6% were worried about detecting breast cancer, 22% reported that they should not touch their bodies, 44% and 28% reported BSE is embarrassing or unpleasant, 29% time consuming, 22% thought they would never have breast cancer or it is ineffective and finally 20% perceived BSE as unimportant. Logistic regression modeling showed that respondents aged ≥45 years, being Malay, married and having a high education level were more likely to practice BSE (p<0.05).

    CONCLUSION: In this study sample, a significant proportion of respondents was aware of breast cancer but did not practice BSE. Knowledge, psychological, cultural, perception and environmental factors were identified as barriers. BSE practice was associated significantly with socio-demographic factors and socioeconomic status.

  4. Factors associated with success or failure of quit attempts: a clinical approach for lung cancer prevention
    Su TT, Sallehuddin BA, Murniati HH, Swinder J, Al Sadat N, Saimy I
    Asian Pac J Cancer Prev, 2012;13(1):175-9.
    PMID: 22502663
    The objective of the study is to investigate the success rate of quit attempts and identify factors associated with success or failure of quit attempts in a quit smoking clinic. A cohort study was conducted with 495 smokers who enrolled in a quit smoking clinic from 2005 to 2008. The factors leading to quit smoking successfully were "being Malay", "having high blood pressure" "type of Nicotine Replacement Therapy" and "duration of follow up". In contrast, clerical staff had negative association to quit smoking. People who started smoking in their teenage years had a high risk of relapse. Integration of active follow up and tailor-made support programmes for quitters appear necessary in order to maintain their non-smoking status and encourage them to be permanent quitters. Integration of quit smoking clinics and primary care clinics could be another potential step for the success of quit smoking programmes.

    PMID: 22822641 MyJurnal
    Cognitive impairment is a common psychiatric problem among the elderly. The objective of the study was to determine the prevalence of cognitive impairment among the elderly Malays living in a rural community in north Malaysia. A cross sectional study was conducted among the elderly population of 22 villages in north Malaysia. Elderly cognitive assessment questionnaire was used to determine the cognition status. Analysis was done using SPSS version 13. The prevalence of cognitive impairment among the older adults in these villages was 11% (n=46). There was an increasing prevalence of cognitive impairment with increasing age (p < 0.05). Being unmarried (OR 2.31), unemployed (OR 2.74) and living alone (OR 2.32) were significantly associated with the risk of being cognitively impairment. Being unemployed (OR 2.29) was a significant predictor variable for cognitive impairment. Similar to other studies conducted in Malaysia the prevalence of cognitive impairment was high.

    Zainal Badari SA, Arcot J, Haron SA, Paim L, Sulaiman N, Masud J
    Ecol Food Nutr, 2012;51(4):265-99.
    PMID: 22794127 DOI: 10.1080/03670244.2012.674445
    Food variety scores (FVS) and dietary diversity scores (DDS) were estimated based on foods consumed weekly by 285 Malaysian households using a food frequency questionnaire. The scoring system of FVS and DDS was based on a scale of 0-7 and 0-6 respectively. The mean household FVS and DDS was 164.1 ± 93 and 6 ± 0.4. The age of respondents (husbands or wives; p < .01), sex (p < .05), and household food expenditure (p < .01) had a significant influence on both FVS and DDS. The food-intake pattern of Malaysian households showed that their typical diets had high protein and energy-based foods.

    Med J Malaysia, 2012 Feb;67(1):81-6.
    PMID: 22582554 MyJurnal
    Sensorineural hearing loss is a common and important source of disability among the workers and often caused by occupational noise exposure. Aims of the study were to determine the prevalence and contributing factors of hearing loss among airport workers. A cross-sectional study was carried out at an airport in Malaysia. This study used stratified sampling method that involved 358 workers who were working in 3 different units between November 2008 and March 2009. Data for this study were collected by using questionnaires eliciting sociodemographic, occupational exposure history (previous and present), life-style including smoking habits and health-related data. Otoscopic and pure-tone audiometric tests were conducted for hearing assessment. Noise exposure status was categorize by using a noise logging dosimeter to obtain 8-hour Time-Weighted Average (TWA). Data was analyzed by using SPSS version 12.0.1 and EpiInfo 6.04. The prevalence of hearing loss was 33.5%. Age >40 years old (aOR 4.3, 95%CI 2.2-8.3) is the main risk factors for hearing loss followed by duration of noise exposure >5 years (aOR 2.5, 95%CI 1.4-4.7), smoking (aOR 2.1, 95%CI 1.2-3.4), duration of service >5 years (aOR 2.1, 95%CI 1.1-3.9), exposure to explosion (aOR 6.1, 95%CI 1.3-29.8), exposure to vibration (aOR 2.2, 95%CI 1.1-4.3) and working in engineering unit (aOR 5.9, 95%CI 1.1-30.9). The prevalence rate ratio of hearing loss for nonsmokers aged 40 years old and younger, smokers aged 40 years old and younger, non-smokers older than 40 years old and smokers older than 40 years old was 1.0, 1.7, 2.8 and 4.6 respectively. This result contributes towards better understanding of risk factors for hearing loss, which is relatively common among Malaysian workers.

    Ghazali AR, Abdul Razak NE, Othman MS, Othman H, Ishak I, Lubis SH, et al.
    J Environ Public Health, 2012;2012:758349.
    PMID: 22536276 DOI: 10.1155/2012/758349
    Heavy metals, particularly cadmium, lead, and arsenic, constitute a significant potential threat to human health. This study was conducted to determine the levels of cadmium, lead, and arsenic in nail samples from farmers at Muda Agricultural Development Authority (MADA), Kedah, Malaysia, and evaluate factors that can contribute to their accumulations. A total of 116 farmers participated in this study. Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze concentration of heavy metals in the nail samples and questionnaires were given to participants to get demographic, health status, and their agricultural activities data. In this paper, the level of heavy metals was within the normal range and varies according to demographic factors. We found that there were significant correlations between working period with level of lead and arsenic (r=0.315 and r=0.242, resp., P<0.01) and age with lead level (r=0.175, P<0.05). Our findings suggested that agricultural activities could contribute to the accumulation of heavy metals in farmers. Hence, the control of environmental levels of and human exposure to these metals to prevent adverse health effects is still an important public health issue.

  10. Fulltext Factors predicting outcome of cardiopulmonary resuscitation among elderly Malaysians: a retrospective study
    Nik Muhamad NA, Nidzwani S
    Med J Malaysia, 2012 Jun;67(3):278-83.
    PMID: 23082417 MyJurnal
    Cardiopulmonary resuscitation (CPR) has been standard treatment for all cardiac arrest patients that arrive at the Emergency Department. However it is unclear whether prolonging resuscitation among the elderly victims will provide any benefit or improve outcome. This study is to evaluate factors that can influence outcome of CPR among the elderly, such as time of arrest, duration of CPR, lactate levels and age (among elderly age groups). 89 patients fit the inclusion criteria from January 2007 to January 2009, and all underwent CPR. Lactate levels (p=0.047) and duration of CPR performed (p=0.019) had significant relation to outcome. Time of arrest to CPR and age had no significance. Of 89 patients studied, 4 (4.5%) survived to hospital discharge. The remaining 85 (95.5%) died either in the emergency department, the wards or the Intensive Care Unit. Among the survivors, only 2 (2.3%) functional (independent on activities of daily life) patients were identified. Among the survivors, the mean lactate level was 4.0 mmol/L. The mean lactate levels among the dead were 9.84 mmol/L. The mean length of CPR among the survivors was 5.42 minutes and for the non-survivors, 19.28 minutes. This study reports certain factors such as duration of resuscitation and initial lactate levels that can be valuable tools in decision making when resuscitating an elderly.

    PMID: 23017466 DOI: 10.1016/j.appet.2012.09.011
    The aim of this study was to assess nutritional supplement use among fitness club participants in Tehran, Iran. A cross sectional study was conducted in 24 fitness clubs throughout the city of Tehran, Iran. A total of 1625 fitness club participants were recruited to participate in this study. They were asked to complete a self-administered pre-tested questionnaire. Descriptive statistics and chi-square test were performed to determine the characteristics of participants, reasons for supplement use, sources of information and also the influential advisors regarding nutritional supplement use. A high prevalence rate of nutritional supplement use (66.7%) was reported. Overall, multivitamin-mineral (43.8%) and iron tablets (30.5%) were the common nutritional supplements used and only a small number of participants used illegal substances (0.5%). Younger participants were more likely to use ergogenic aids, whereas, older participants were more likely to use vitamin D. Males were more likely than females to use creatine and amino acids, whereas, iron tablets and mint water were more common among females. Also, males were more likely to use nutritional supplements for increasing energy, whereas, females were more likely to use nutritional supplements for nutritional deficiencies. In conclusion, a high prevalence rate of nutritional supplement use was seen among participants.

  12. Inappropriate prescribing in hospitalised Australian elderly as determined by the STOPP criteria
    Wahab MS, Nyfort-Hansen K, Kowalski SR
    Int J Clin Pharm, 2012 Dec;34(6):855-62.
    PMID: 22864867 DOI: 10.1007/s11096-012-9681-8
    BACKGROUND: The elderly population is increasing worldwide. Due to age-related physiological changes that affect the pharmacokinetics and pharmacodynamics of drugs, the elderly are predisposed to adverse drug reactions. Prescribing of potentially inappropriate medications (PIMs) has been found to be prevalent among the elderly and PIM use has been associated with hospitalisations and mortality.

    OBJECTIVES: This study aims to identify the prevalence and nature of pre-admission inappropriate prescribing by using the STOPP (screening tool of older people's prescriptions) criteria amongst a sample of hospitalised elderly inpatients in South Australia.

    SETTING: Medical, surgical and rehabilitation wards of a public teaching hospital in Adelaide, South Australia.

    MAIN OUTCOME MEASURE: Pre-admission prevalence of PIM.

    METHOD: Medication management plans of 100 patients of ≥65 years old were prospectively studied to determine the prevalence of pre-admission PIM use. Sixty-five criteria of STOPP were applied to identify PIMs.

    RESULTS: The total number of pre-admission medications screened during the study period was 949; the median number of medicines per patient was nine (range 2-28). Overall the STOPP criteria identified 138 PIMs in 60 % of patients. The most frequently encountered PIM was opiates prescribed in patients with recurrent falls (12.3 %), followed by benzodiazepines in fallers (10.1 %) and proton pump inhibitors when prescribed for peptic ulcer disease for long-term at maximum doses (9.4 %). The number of medications were found to have a positive correlation with pre-admission PIM use (r(s) = 0.49, P < 0.01).

    CONCLUSIONS: Pre-admission PIM use is highly prevalent among the studied population. Strategies to reduce PIM use should be undertaken by physicians and pharmacists. The use of the STOPP criteria in clinical practice to reduce prescriptions of inappropriate medications requires further investigation.

  13. Prevalence of piriformis syndrome in chronic low back pain patients. A clinical diagnosis with modified FAIR test
    Kean Chen C, Nizar AJ
    Pain Pract, 2013 Apr;13(4):276-81.
    PMID: 22863240 DOI: 10.1111/j.1533-2500.2012.00585.x
    Piriformis syndrome is a collection of symptoms and signs of pain from piriformis muscle and is characterized by pain in buttock with variable involvement of sciatic nerve. This syndrome is often overlooked in clinical practice because its presentation has similarities with other spine pathologies. A major problem with the clinical diagnosis of piriformis syndrome is the lack of consistent objective findings and an absence of single test that is specific for piriformis syndrome. Therefore, a precise and reliable clinical method of diagnosing piriformis syndrome should be developed by clinicians.

  14. Refining clinical phenotypes by contrasting ethnically different populations with schizophrenia from Australia, India and Sarawak
    McLean D, John S, Barrett R, McGrath J, Loa P, Thara R, et al.
    Psychiatry Res, 2012 Apr 30;196(2-3):194-200.
    PMID: 22401968 DOI: 10.1016/j.psychres.2011.12.027
    We contrasted demographic and clinical characteristics in transethnic schizophrenia populations from Australia (n=821), India (n=520) and Sarawak, Malaysia (n=298) and proposed cultural explanations for identified site differences. From these we aimed to identify candidate variables free from significant cultural confounding that are hence suitable for inclusion in genetic analyses. We observed five phenomena: (1) more individuals were living alone in Australia than India or Sarawak; (2) drug use was lower in India than Australia or Sarawak; (3) duration of untreated psychosis (DUP) was longer in India than Australia or Sarawak; (4) the rate of schizoaffective disorder was lower in India than Australia or Sarawak; and (5) age at psychosis onset (AAO) was older in Sarawak than Australia or India. We suggest that site differences for living arrangements, drug use and DUP are culturally confounded. The schizoaffective site difference likely results from measurement bias. The AAO site difference, however, has no obvious cultural or measurement bias explanation. Therefore, this may be an ideal candidate for use in genetic studies, given that genetic variants affecting AAO have already been proposed.

  15. Quantitative ultrasound measurement of the calcaneus in Southeast Asian children with thalassemia: comparison with dual-energy X-ray absorptiometry
    Sani FM, Sarji SA, Bilgen M
    J Ultrasound Med, 2011 Jul;30(7):883-94.
    PMID: 21705720
    OBJECTIVES: The purpose of this study was to test the hypothesis that quantitative ultrasound properties of the calcaneus in Southeast Asian children treated for thalassemia have different characteristics than those of their healthy counterparts and thereby can be used for assessing the risk of osteoporosis.

    METHODS: Broadband ultrasound attenuation and the speed of sound were measured from groups of thalassemic and healthy children and compared with bone mineral density (BMD) estimated from dual-energy X-ray absorptiometry to determine intergroup and intragroup dependencies of the measurements and variations with differences in sex and anthropometric characteristics.

    RESULTS: Broadband ultrasound attenuation and speed of sound measurements were found to be independent of sex but dependent on age in the thalassemic children. Consistently, broadband ultrasound attenuation had lower values and the speed of sound had higher values compared with those of the healthy children in each age group. Broadband ultrasound attenuation correlated well with the speed of sound and also with age, weight, and height, but the speed of sound did not show an association with these parameters. Broadband ultrasound attenuation correlated moderately with BMD in the lumbar spine and whole body, but the corresponding association was much weaker for the speed of sound. In the thalassemic children, both broadband ultrasound attenuation and BMD increased with age as they grew older but not fast enough compared with the healthy children, and the risk of osteoporosis was greater at older ages.

    CONCLUSIONS: Calcaneal quantitative ultrasound may be used as a diagnostic screening tool for assessing the bone status in thalassemic Southeast Asian children and for deciding whether further dual-energy X-ray absorptiometry is needed, particularly in those who are at a greater risk for osteoporosis as identified by low body weight and height.

    PMID: 22285457 DOI: 10.1016/j.jvoice.2011.08.008
    The formant frequencies of Malaysian Malay children have not been well studied. This article investigates the first four formant frequencies of sustained vowels in 360 Malay children aged between 7 and 12 years using acoustical analysis. Generally, Malay female children had higher formant frequencies than those of their male counterparts. However, no significant differences in all four formant frequencies were observed between the Malay male and female children in most of the vowels and age groups. Significant differences in all formant frequencies were found across the Malay vowels in both Malay male and female children for all age groups except for F4 in female children aged 12 years. Generally, the Malaysian Malay children showed a nonsystematic decrement in formant frequencies with age. Low levels of significant differences in formant frequencies were observed across the age groups in most of the vowels for F1, F3, and F4 in Malay male children and F1 and F4 in Malay female children.

    Muhammad BG, Jaafar MS, Azhar AR, Akpa TC
    Radiat Prot Dosimetry, 2012 Apr;149(3):340-6.
    PMID: 21642647 DOI: 10.1093/rpd/ncr230
    Measurements of (222)Rn activity concentration were carried out in 39 samples collected from the domestic and drinking water sources used in the island and mainland of Penang, northern peninsular, Malaysia. The measured activity concentrations ranged from 7.49 to 26.25 Bq l(-1), 0.49 to 9.72 Bq l(-1) and 0.58 to 2.54 Bq l(-1) in the raw, treated and bottled water samples collected, respectively. This indicated relatively high radon concentrations compared with that from other parts of the world, which still falls below the WHO recommended treatment level of 100 Bq l(-1). From this data, the age-dependent associated committed effective doses due to the ingestion of (222)Rn as a consequence of direct consumption of drinking water were calculated. The committed effective doses from (222)Rn resulting from 1 y's consumption of these water were estimated to range from 0.003 to 0.048, 0.001 to 0.018 and 0.002 to 0.023 mSv y(-1), for age groups 0-1, 2-16 and >16 y, respectively.

  19. Fulltext Capsular serotype and antibiotic resistance of Streptococcus pneumoniae isolates in Malaysia
    Le CF, Palanisamy NK, Mohd Yusof MY, Sekaran SD
    PLoS One, 2011;6(5):e19547.
    PMID: 21603602 DOI: 10.1371/journal.pone.0019547
    BACKGROUND: Streptococcus pneumoniae is a major causative agent of severe infections, including sepsis, pneumonia, meningitis, and otitis media, that has since become a major public health concern. In this study, the serotypes distribution of pneumococcal isolates was investigated to predict the efficacy of the 7-valent pneumococcal conjugate vaccine (PCV7) among the Malaysian populations.
    METHODOLOGY/PRINCIPAL FINDINGS: A total of 151 clinical isolates were serotyped using multiplex PCR assays. Out of them, there were 21.2% penicillin-resistant, 29.1% penicillin-intermediate, and 49.7% penicillin-susceptible S. pneumoniae strains. Serotypes detected among the Malaysian isolates were 1, 3, 10A, 11A/11D, 12F/12A, 14, 15A, 15B/15C, 16F, 18C/18B/18A/18F, 19A, 19F, 23F, 35B, 35F/47F, 6A/6B, 7C/7B/40, 7F/7A, 9V/9A, and 34. Serotype 19F and 23F were the two most prevalent serotypes detected. Serotypes are highly associated with invasiveness of isolates (p = 0.001) and penicillin susceptibility (p<0.001). Serotype 19F was observed to have increased resistance against penicillin while serotype 19A has high invasive tendency. Age of patients was an important factor underlying the pneumococcal serotypes (p = 0.03) and clinical sites of infections (p<0.001). High prevalence of pneumococcal isolates were detected among children <5 years old at nasopharyngeal sites while elderly adults ≥60 years old were at increased risk for pneumococcal bacteremia.
    CONCLUSION/SIGNIFICANCE: Current study revealed that a number of serotypes, especially those associated with high penicillin resistance, have been formulated in the PCV7. Therefore, the protections expected from the routine use of PCV7 would be encouraging for the Malaysian. However, it is not possible to predict serotypes that might become predominant in the future and hence continued surveillance of circulating serotypes will be needed.

    Int J Pediatr Obes, 2011 Aug;6(3-4):229-35.
    PMID: 21668385 DOI: 10.3109/17477166.2011.583658
    BACKGROUND: The prevalence of obesity is increasing rapidly and abdominal obesity especially is known to be a risk factor for metabolic syndrome and other non-communicable diseases. Waist circumference percentile curves are useful tools which can help to identify abdominal obesity among the childhood and adolescent populations.
    OBJECTIVE: To develop age- and sex-specific waist circumference (WC) percentile curves for multi-ethnic Malaysian children and adolescents aged 6.0-16.9 years. Subjects and methods. A total of 16,203 participants comprising 8,093 boys and 8,110 girls recruited from all regions of Malaysia were involved in this study. Height, weight, WC were measured and BMI calculated. Smoothed WC percentile curves and values for the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and 97th percentiles were constructed using the LMS Method.
    RESULTS: WC was found to increase with age in both sexes, but boys had higher WC values at every age and percentile. Z-scores generated using the UK reference data shows that Chinese children had the highest WC compared to Malays, Indians and other ethnicities. Comparisons with other studies indicate that at the 50th percentile, Malaysian curves did not differ from the UK, Hong Kong and Turkish curves, but at the 90th percentile, Malaysian curves were higher compared with other countries, starting at 10 years of age. The 90th percentile was adopted as the cut-off point to indicate abdominal obesity in Malaysian children and adolescents.
    CONCLUSION: These curves represent the first WC percentiles reported for Malaysian children, and they can serve as a reference for future studies.
