Fulltext Seroprevalence of toxocariasis among Orang Asli (Indigenous people) in Malaysia using two immunoassays

Romano N, Nor Azah MO, Rahmah N, Lim Y AL, Rohela M

Trop Biomed, 2010 Dec;27(3):585-94.
PMID: 21399601 MyJurnal

Toxocariasis is a zoonotic helminthic infection of humans caused by the dog roundworm (Toxocara canis) or cat roundworm (Toxocara cati). There are two main human syndromes: visceral larva migrans (VLM), which are characterized by symptoms associated with major organs and ocular larva migrans (OLM), in which pathological effects on the host are restricted to the eye and the optic nerve. The present study evaluated the seroprevalence of toxocariasis among the Orang Asli with an IgG4-ELISA using recombinant antigens (rTES-26, rTES-30 and rTES-120) and an IgG-ELISA commercial kit (Cypress Diagnostic, Belgium). A total of 188 serum samples were analyzed using IgG4-ELISA recombinant antigens while 83 were tested using IgG-ELISA. Overall, 9 out of 188 (4.8%) samples were positive with the former assay: rTES-26 (2.7%) and rTES-30 (2.1%); and 63 out of 83 (75.9%) were positive with the IgG-ELISA. In general, the seroprevalence of toxocariasis among males (9.5%) was higher compared to females (1%). Children below 12 years (6.3%) have higher seroprevalence rate compared to adults (1.2%). Out of 59 IgG positive samples, 56 (94.9%) were also positive with soil-transmitted helminth (STH) infections which may indicate high false positivity. None of the IgG4- ELISA positive samples were positive with STH infections. Of 9 positive samples with IgG4-ELISA, 7 were also positive with IgG-ELISA giving the probability of true cases. The present finding indicated that exposure to Toxocara infection is not unusual among Malaysian aborigines, and it affects both sexes and all age groups. As a prevention strategy, more effective public health programmes to promote better understanding on the consequences of toxocariasis among the Orang Asli communities are deemed necessary.

Fulltext Anthropometric and cardiometabolic risk factors in parents and child obesity in Segamat, Malaysia

Partap U, Young EH, Allotey P, Sandhu MS, Reidpath DD

Int J Epidemiol, 2017 Oct 01;46(5):1523-1532.
PMID: 29106558 DOI: 10.1093/ije/dyx114

BACKGROUND: There is little evidence regarding risk factors for child obesity in Asian populations, including the role of parental anthropometric and cardiometabolic risk factors. We examined the relation between parental risk factors and child obesity in a Malaysian population.
METHODS: We used data from health and demographic surveillance conducted by the South East Asia Community Observatory in Segamat, Malaysia. Analyses included 9207 individuals (4806 children, 2570 mothers and 1831 fathers). Child obesity was defined based on the World Health Organization 2007 reference. We assessed the relation between parental anthropometric (overweight, obesity and central obesity) and cardiometabolic (systolic hypertension, diastolic hypertension and hyperglycaemia) risk factors and child obesity, using mixed effects Poisson regression models with robust standard errors.
RESULTS: We found a high burden of overweight and obesity among children in this population (30% overweight or obese). Children of one or more obese parents had a 2-fold greater risk of being obese compared with children of non-obese parents. Sequential adjustment for parental and child characteristics did not materially affect estimates (fully adjusted relative risk for obesity in both parents: 2.39, 95% confidence interval: 1.82, 3.10, P

Lim TO, Ding LM, Goh BL, Zaki M, Suleiman AB, Maimunah AH, et al.

Med J Malaysia, 2000 Mar;55(1):90-107.
PMID: 11072495 MyJurnal

We describe the distribution of blood pressure (BP) by age, sex and ethnicity in Malaysian adults. A national sample of 21,391 individuals aged 30 or older had usable data. They were selected by stratified 2-stage cluster sampling. BP was measured using an automated oscillometric device, Visomat. Percentile tables and curves by age, sex and ethnicity are presented. The systolic and diastolic BP distribution was right skewed and showed the expected increase with age. This was markedly so in Malay and other indigenous women; as a result they had most severe hypertension.

Maxillofacial trauma with emphasis on soft-tissue injuries in Malaysia

Hussaini HM, Rahman NA, Rahman RA, Nor GM, Ai Idrus SM, Ramli R

Int J Oral Maxillofac Surg, 2007 Sep;36(9):797-801.
PMID: 17630250

Soft-tissue injuries with or without facial bone involvement are the most common presentation following maxillofacial trauma. The objective of this study was to look at the distribution, pattern and type of soft-tissue injury in relation to aetiology. Records of patients over a period of 5 years (1998-2002), who sustained maxillofacial injuries and were treated at Kajang Hospital, a secondary referral hospital, were reviewed. Out of 313 patients with maxillofacial injuries, 295 patients sustained soft-tissue injuries. Males (79%) between 21 and 30 years old (34%) were the majority of patients. Road-traffic accident was the main cause of soft-tissue injuries (75%) with motorcycle accident being the most frequent (40%). The upper lips (23%) and the lower lips (18%) were the most common extraoral site involved, while the labial mucosa and sulcular areas, both accounting for 21%, were the most common intraoral sites. Stringent road-traffic regulations should be practiced in developing countries, as morbidity arising from road-traffic accidents poses a national economic and social problem.

Fulltext Cervical cancer in Brunei Darussalam

Lee MY, Telisinghe PU, Ramasamy R

Singapore Med J, 2012 Sep;53(9):604-7.
PMID: 23023903

Introduction Cervical cancer caused by the human papilloma virus (HPV) is a common cancer in women. There is no published data on the recent incidence of cervical dysplasia, cervical cancer and genital warts caused by the different types of HPVs in Brunei Darussalam.
Methods A cross-sectional, retrospective study was conducted utilising data from patients diagnosed with cervical cancer during the period 2005–2009 in Brunei Darussalam. The varying incidences of different types of cervical lesions among various ethnic and age groups, and in the overall population, were determined.
Results The mean age-standardised incidence of invasive cervical cancer during the five-year period was 24.9 per 100,000 women per year (95% confidence interval [CI] 21.7, 28.1). Age-specific invasive cervical cancer incidence peaked in the age group 45–59 years. Chinese females tended to have a higher incidence of invasive cervical cancer (28.2 per 100,000 women per year; 95% CI 17.8, 38.7) than Malay females (20.6 per 100,000 women per year; 95%
CI 17.1, 24.2), while other ethnic groups in Brunei Darussalam had a significantly lower incidence (6.5 per 100,000 women per year; 95% CI 3.0, 10.0).
Conclusion The results suggest that Brunei Darussalam has a relatively higher incidence of cervical cancer compared to its neighbouring countries. The findings support the need for more comprehensive screening, public education programmes and vaccination against HPV in the country.

Fulltext How can gastro-intestinal tuberculosis diagnosis be improved? A prospective cohort study

Lowbridge C, Fadhil SAM, Krishnan GD, Schimann E, Karuppan RM, Sriram N, et al.

BMC Infect Dis, 2020 Mar 30;20(1):255.
PMID: 32228479 DOI: 10.1186/s12879-020-04983-y

BACKGROUND: Gastrointestinal tuberculosis (TB) is diagnostically challenging; therefore, many cases are treated presumptively. We aimed to describe features and outcomes of gastrointestinal TB, determine whether a clinical algorithm could distinguish TB from non-TB diagnoses, and calculate accuracy of diagnostic tests.
METHODS: We conducted a prospective cohort study of hospitalized patients in Kota Kinabalu, Malaysia, with suspected gastrointestinal TB. We recorded clinical and laboratory characteristics and outcomes. Tissue samples were submitted for histology, microscopy, culture and GeneXpert MTB/RIF®. Patients were followed for up to 2 years.
RESULTS: Among 88 patients with suspected gastrointestinal TB, 69 were included in analyses; 52 (75%) had a final diagnosis of gastrointestinal TB; 17 had a non-TB diagnosis. People with TB were younger (42.7 versus 61.5 years, p = 0.01) and more likely to have weight loss (91% versus 64%, p = 0.03). An algorithm using age 26 g/L, platelets > 340 × 109/L and immunocompromise had good specificity (96.2%) in predicting TB, but very poor sensitivity (16.0%). GeneXpert® performed very well on gastrointestinal biopsies (sensitivity 95.7% versus 35.0% for culture against a gold standard composite case definition of confirmed TB). Most patients (79%) successfully completed treatment and no treatment failure occurred, however adverse events (21%) and mortality (13%) among TB cases were high. We found no evidence that 6 months of treatment was inferior to longer courses.
CONCLUSIONS: The prospective design provides important insights for clinicians managing gastrointestinal TB. We recommend wider implementation of high-performing diagnostic tests such as GeneXpert® on extra-pulmonary samples.

Fulltext The prevalence and intensity of soil-transmitted helminths in some rural villages in northern peninsular Malaysia

Rahman WA

Southeast Asian J. Trop. Med. Public Health, 1994 Jun;25(2):296-9.
PMID: 7855643

The prevalence and intensity of soil-transmitted helminths in five rural villages in northern peninsular were investigated. Generally the prevalence and intensity of infection were low in the 0-10- and above 50-year-old age groups when compared with other age groups. The prevalence and intensity of infection in the five villages were quite similar, because of similar socio-economic status. The highest intensity was observed for Ascaris lumbricoides, followed by hookworms and Trichuris trichiura.

Prevalence, awareness, treatment and control of hypertension in Malaysia: a national study of 16,440 subjects

Rampal L, Rampal S, Azhar MZ, Rahman AR

Public Health, 2008 Jan;122(1):11-8.
PMID: 17981310 DOI: 10.1016/j.puhe.2007.05.008

Study design: A cross-sectional study was conducted in all states of Malaysia to determine the prevalence, awareness, treatment and control of hypertension. A stratified two-stage cluster sampling design with proportional allocation was used.
Methods: Trained nurses obtained two blood pressure measurements from each subject. Hypertension was defined as mean systolic blood pressure >140 mmHg, diastolic blood pressure >90 mmHg, or a self-reported diagnosis of hypertension and taking antihypertensive medication. All data were analysed using Stata 9.2 software and took the complex survey design into account. A two-sided P-value of <0.05 was considered to be statistically significant.
Results: The overall prevalence of hypertension for subjects aged 15 years was 27.8% (95% confidence interval (CI) 26.9-28.8). The prevalence of hypertension was significantly higher in males (29.6%, 95% CI 28.3-31.0) compared with females (26.0%, 95% CI 25.0-27.1). Multivariate logistic regression showed that the odds of having hypertension increased with increasing age, in males, in subjects with a family history of hypertension, with increasing body mass index, in non-smokers and with decreasing levels of education. Only 34.6% of the subjects with hypertension were aware of their hypertensive status, and 32.4 were taking antihypertensive medication. Amongst the latter group, only 26.8% had their blood pressure under control. The prevalence of hypertension amongst those aged 30 years has increased from 32.9% in 1996 to 40.5% in 2004.
Conclusion: In Malaysia, the prevalence of hypertension is high, but levels of awareness, treatment and control are low. There is an urgent need for a comprehensive integrated population-based intervention programme to ameliorate the growing problem of hypertension in Malaysians.

Fulltext Socio-demographic, environmental and caring risk factors for childhood drowning deaths in Bangladesh

Hossain M, Mani KK, Sidik SM, Hayati KS, Rahman AK

BMC Pediatr, 2015;15:114.
PMID: 26357879 DOI: 10.1186/s12887-015-0431-7

Drowning contributes to incapacity and early death in many countries. In low- and middle-income countries, children are the most susceptible to fatalities. Over 50 % of the global drowning deaths occur among children aged under 15 years old with children aged between 1 and 4 years of age being most at risk. In Bangladesh, drowning rates are 10 to 20 times more than those in other developing countries. The object of this study is to determine the socio-demographic, environmental and caring hazard issues for child drowning in Bangladesh.

Field validation of sensitivity and specificity of rapid test for detection of Brugia malayi infection

Jamail M, Andrew K, Junaidi D, Krishnan AK, Faizal M, Rahmah N

Trop Med Int Health, 2005 Jan;10(1):99-104.
PMID: 15655019

We conducted a field study of a rapid test (Brugia Rapid) for detection of Brugia malayi infection to validate its sensitivity and specificity under operational conditions. Seven districts in the state of Sarawak, Malaysia, which are endemic for brugian filariasis, were used to determine the test sensitivity. Determination of specificity was performed in another state in Malaysia (Bachok, Kelantan) which is non-endemic for filariasis but endemic for soil-transmitted helminths. In Sarawak both the rapid test and thick blood smear preparation were performed in the field. The rapid test was interpreted on site, whereas blood smears were taken to the district health centres for staining and microscopic examination. Sensitivity of Brugia Rapid dipstick as compared with microscopy of thick blood smears was 87% (20/23; 95% CI: 66.4-97.2) whereas the specificity was 100% (512/512). The lower sensitivity of the test in the field than in laboratory evaluations (> or =95%), was probably due to the small number of microfilaraemic individuals, in addition to difficulties in performing the test in remote villages by field personnel. The overall prevalence of brugian filariasis as determined by the dipstick is 9.4% (95% CI: 8.2-0.5) while that determined by microscopy is 0.90% (95% CI: 0.5-1.3) thus the dipstick detected about 10 times more cases than microscopy. Equal percentages of adults and children were found to be positive by the dipstick whereas microscopy showed that the number of infected children was seven times less than infected adults. The rapid dipstick test was useful as a diagnostic tool for mapping and certification phases of the lymphatic filariasis elimination programme in B. malayi-endemic areas.

Rahimah AK

Singapore Dent J, 1994 Jan;19(1):4-7.
PMID: 9582675

To obtain the profile of periodontal conditions in West Malaysian adults, five small scale surveys were carried out on selected occupational adult groups, 20-54 years old, between 1987 to 1990. Periodontal assessment was made using the CPITN index. In all, 779 subjects were examined. Results indicated that only 16% of the adults examined had healthy gingivae. Bleeding of the gingivae was limited to the younger (20-24 years) age group. Calculus is highly prevalent in at least 65.5% of all the subjects examined. Periodontal pockets were limited to mostly shallow pockets and the risk of developing pockets increased with increasing age. Both navy personnel and factory workers showed a higher number of healthy sextants across all ages as compared to the other three occupational groups; viz., rubber tappers, villagers and government workers. The rubber tappers were the only group with deep pockets, with the prevalence ranging between 8 to 25%. Implications of the findings to the Malaysian dental delivery system are discussed.

Fulltext Bacterial enteropathogens isolated in childhood diarrhoea in Kuala Lumpur--the changing trend

Lee WS, Puthucheary SD

Med J Malaysia, 2002 Mar;57(1):24-30.
PMID: 14569714

A retrospective review of all stool samples obtained from children aged < 16 years with diarrhoea from University of Malaya Medical Centre (UMMC), Kuala Lumpur, from 1978 to 1997 was undertaken to ascertain the pattern of bacterial pathogens causing diarrhoea in children in an urban area in Malaysia. Of 26444 stool samples processed, 2989 (11%) were positive. The five most common bacterial pathogens isolated were non-typhoidal Salmonella (57%), enteropathogenic E. coli (EPEC) (14%), Shigella spp. (11%), Campylobacter spp. (5%) and Aeromonas spp. (4%). There was a significant reduction in the average percentage of positive isolation during the last 5 years of the study period as compared to the first 5 years (15.0% vs. 7.2%; r = -0.92, p = 0.0001). EPEC and Shigella spp. were less commonly isolated in the last five years compared with the first five years of the study (6% vs 21% p < 0.001 for E. coli; 7% vs 22%, p < 0.001 for Shigella spp.). This information is important for public health education in reducing the incidence of childhood diarrhoea further, and in the selection of appropriate antimicrobials in the management of extra-intestinal complications of childhood diarrhoea.

Epidemiology of malaria in Attapeu Province, Lao PDR in relation to entomological parameters

Vythilingam I, Sidavong B, Chan ST, Phonemixay T, Vanisaveth V, Sisoulad P, et al.

Trans R Soc Trop Med Hyg, 2005 Nov;99(11):833-9.
PMID: 16112154

Surveys were conducted in malaria-endemic villages in the southern province of Attapeu, Lao PDR during various seasons over a 3-year period. All-night mosquito landing collections, blood surveys and a case-control study were conducted. Plasmodium falciparum was the predominant species, and slide positivity rates were higher during the transition/dry season compared with the wet season. Anopheles dirus A was found to be the primary vector, and sporozoite rates were highest during the transition/dry season. Anopheles dirus was found to be endophagic and endophilic. Not using insecticide-treated bed nets, houses close to breeding sites and sleeping away from home were risk factors associated with malaria.

Fulltext Attitudes of the public towards halal food and associated animal welfare issues in two countries with predominantly Muslim and non-Muslim populations

Jalil NSA, Tawde AV, Zito S, Sinclair M, Fryer C, Idrus Z, et al.

PLoS One, 2018;13(10):e0204094.
PMID: 30379818 DOI: 10.1371/journal.pone.0204094

Halal food is that which is permissible or lawful for Muslims to consume. Meat products must abide by a number of requirements in relation to their preparation, condition and content to be considered halal. We conducted a survey in order to assess the knowledge of, and attitudes towards, halal meat products in two contrasting countries, one with a majority non-Muslim population (Australia, respondent n = 565), where the most commonly followed religion is Christianity, and one with a majority Muslim population (Malaysia, n = 740). The most common reasons for avoiding halal food were animal welfare, religion and meat quality. Malaysians generally believed that halal processes led to improved meat quality, whereas Australians did not. The general consensus was in favour of legally controlling animal welfare during slaughter, supported by both Muslims and Christians. Malaysians were more aware of the main tenets of halal slaughter than Australians. However, some non-compulsory, incorrect practices were thought to be required practices by respondents in both countries, but especially in Australia. Muslims were more concerned about humane treatment of animals during halal slaughter. They generally believed that stunning is never allowed and that this view was acceptable, whereas people from other belief systems generally held the view that this was unacceptable. Religion and education were the most common factors associated with attitudes, beliefs and consumer habits concerning halal. Information from this study can help to improve understanding of attitudes to halal and provide insights to policy makers seeking to address animal welfare concerns.

Psychological distress and its association with job satisfaction among nurses in a teaching hospital

Ghawadra SF, Abdullah KL, Choo WY, Phang CK

J Clin Nurs, 2019 Nov;28(21-22):4087-4097.
PMID: 31294501 DOI: 10.1111/jocn.14993

AIM AND OBJECTIVES: To determine the prevalence of psychological distress and its association with job satisfaction among nurses in a teaching hospital in Malaysia.
BACKGROUND: Nurses constitute the majority of health care workers, and, compared with other professions, nursing profession is highly stressful and, hence, a cause of anxiety and depression. This may affect nurses' job satisfaction.
METHOD: Using self-administered questionnaires, Depression Anxiety and Stress Scale (DASS-21) and Job Satisfaction Scale for Nurses (JSS), a cross-sectional study of 932 nurses from the inpatient departments of a teaching hospital was conducted in December 2017. Descriptive analyses and multiple logistic regressions were used for the analysis. The STROBE guideline was used in this study.
RESULTS: The overall prevalence of psychological distress was 41%. The prevalence of stress, anxiety and depression were 14.4%, 39.3% and 18.8%, respectively. It was found that single and widowed nurses had a higher level of stress, anxiety and depression compared with married nurses. In addition, nurses in the age of 26-30 years had a higher level of depression than nurses in other age groups. Also, nurses who worked in the paediatric departments had a higher level of depression compared with nurses in other departments. The majority of the nurses were satisfied with their job at 92.0%. Those nurses who were not satisfied were found to be significantly associated with a high level of stress and depression.
CONCLUSION: This study revealed that the level of stress, anxiety and depression is high. Stress and depression were found to be associated with nurses' low job satisfaction.
RELEVANCE TO CLINICAL PRACTICE: Stress and depression can affect nurses' job satisfaction, it is important for nursing managers to institute strategies to address this issue.
