This study aimed to examine the duration to achieve first blood pressure (BP) control after the diagnosis of hypertension. This was a retrospective cohort study on 195 hypertensive patients' (age ≥18 years) records from a primary health care clinic. The median time to achieve first BP control was 7.2 months (95% confidence interval [CI] = 4.99-9.35). Cox proportional hazards regression results showed female patients were 1.5 times more likely to achieve BP control when compared with male patients (hazard ratio [HR] = 1.50, 95% CI 1.09-2.09, P = .013). Those with monotherapy were 2 times more likely (HR = 2.09, 95% CI = 1.39-3.13, P < 0.001) and those on 2 drugs were 3.5 times more likely (HR = 3.49, 95% CI = 1.65-7.40, P = .001) to achieve BP control than those with nonpharmacological treatment. The median time to achieve BP control was longer than the recommended time. Doctors may need to consider starting the pharmacological treatment early and be more aggressive in hypertensive management for male patients.
Nipah virus is a highly pathogenic but poorly known paramyxovirus from South and Southeast Asia. In spite of the risks that it poses to human health, the geography and ecology of its occurrence remain little understood-the virus is basically known from Bangladesh and peninsular Malaysia, and little in between. In this contribution, I use documented occurrences of the virus to develop ecological niche-based maps summarizing its likely broader occurrence-although rangewide maps could not be developed that had significant predictive abilities, reflecting minimal sample sizes available, maps within Bangladesh were quite successful in identifying areas in which the virus is predictably present and likely transmitted.
Adolescent tobacco use (ATU) is on the rise worldwide and the problem is particularly severe in developing countries. Based on nationally representative data, this study aims to investigate the association between ATU and its possible correlates for Bangladesh, where the prevalence rate of ATU is high. The data set is extracted from the Global Youth Tobacco Survey for Bangladesh conducted in 2007. The survey collected information from a total of 3113 students from 52 schools, with a response rate of 100% at the school level, while a response rate of 88.9% was achieved from the students. Students covered in the survey were in grades 7, 8, 9, and 10, with age ranging from 11 to 17 years. The prevalence rate of ATU at the time of the survey was 8.4%, while 35.6% of the students had used at least a type of tobacco products before. Logistic regressions were used to obtain the odds ratios (ORs) in favor of ATU for each of the possible determinants and the confidence intervals (CIs) of these ratios. Use of tobacco among friends (OR = 3.46; CI = 2.37-5.05), the experience of seeing others smoking at home (OR = 2.10; CI = 1.36-3.22) or other places (OR = 1.6; CI = 1.02-2.57), receiving pocket money (OR = 7.6; CI = 4.59-13.28), receiving free tobacco from vendors (OR = 2.3; CI = 1.44-3.78), and exposure to advertisements and promotions of tobacco products (OR = 1.83; CI = 1.23-2.79) were associated with a higher likelihood of ATU. Increased awareness of health hazards of tobacco use through education in schools helped mitigate the problem of ATU. The findings of this study have ramifications for tobacco control prevention strategies in Bangladesh.
Given that breast cancer is the most prevalent form of cancer affecting Malaysian women and its low survival rate, this study investigates the possible influence of support group intervention on quality of life (QOL). It also examines the interrelationships between QOL subdomains as research has shown the influence of emotional expression on psychological and physical well-being. Rasch analysis was implemented to examine perception of QOL and the comparability of the Functional Assessment of Cancer Therapy General and Breast Cancer scales (FACT-G and FACT-B) of the Functional Assessment of Chronic Illness Therapy inventory. Results indicated that perception of QOL may be influenced by factors other than support group intervention. The FACT-G and FACT-B scales were comparable in the measurement of QOL for breast cancer, and the interrelationships between the QOL subdomains were supported. The findings of this study accentuate the importance of focusing support group interventions on improvement of emotional well-being to maintain patients' QOL despite the cancer.

This study investigated the patterns of ongoing work-related musculoskeletal disorders (WRMDs) and exposure risk to musculoskeletal injuries for various body regions among palm plantation workers. Standard Nordic Musculoskeletal Questionnaire (SNMQ) was used to assess the prevalence of musculoskeletal disorders symptoms. The Quick Exposure check (QEC) was used to assess the exposure risk of farmers to WRMDs. The common pattern of WRMDs was back pain (40%), followed by shoulder pain (19%). The QEC revealed high exposure risk for neck (56%), followed by back (45.6%). The results from the SNMQ showed that 58% reported pain in 1 region, followed by 2 regions (10.7%) and 3 regions (3.6%). Back pain and shoulder pain were found to be common among workers in palm plantation occupation. Nevertheless, the neck region appeared to have the highest risk of exposure to injuries.
This survey evaluated the knowledge, attitudes, and practices of general dental practitioners (GDPs) in Selangor regarding early childhood caries (ECC) prevention and the recommended timing of a child's first dental visit. A questionnaire was mailed to 521 licensed GDPs. Descriptive statistics were used, and bivariate and logistic regression analyses were performed. The response rate was 52.6%. Although 89.8% mentioned counseling parents and caregivers, only 44.2% were familiar with anticipatory guidance. Whereas 98.2% agreed that early examinations are important to prevent ECC, only 51.8% were aware of the recommendation for a first visit by 12 months of age. GDPs who recommended early dental visits were significantly more likely to be recent graduates, more familiar with professional guidelines, and less likely to be deterred by a child's crying or behavior. In conclusion, GDPs in Selangor are aware about the importance of early dental visits in ECC prevention. However, a considerable number of them are still not aware of the recommendation that children must first visit the dentist by 12 months of age. Furthermore, some of their current practices in ECC management and prevention do not match professional recommendations.

This study was aimed at validating the simplified Chinese version of the Multidimensional Scale of Perceived Support (MSPSS-SCV) among a group of medical and dental students in University Malaya. Two hundred and two students who took part in this study were given the MSPSS-SCV, the Medical Outcome Study social support survey, the Malay version of the Beck Depression Inventory, the Malay version of the General Health Questionnaire, and the English version of the MSPSS. After 1 week, these students were again required to complete the MSPSS-SCV but with the item sequences shuffled. This scale displayed excellent internal consistency (Cronbach's α = .924), high test-retest reliability (.71), parallel form reliability (.92; Spearman's ρ, P < .01), and validity. In conclusion, the MSPSS-SCV demonstrated sound psychometric properties in measuring social support among a group of medical and dental students. It could therefore be used as a simple screening tool among young educated Malaysian adolescents.

Understanding the factors influencing physical activity (PA) in the Asia-Pacific region is critical, given the high prevalence of inactivity in this area. The photovoice technique explores the types of PA and factors influencing PA among adolescents in Kuching, Sarawak. A total of 160 photographs were collected from participants (adolescents, n = 22, mean age = 14.27 ± 0.7 years, and parents, n = 8, mean age = 48 ± 6.8 years). Data analysis used constant comparison methods of a grounded theory. The Analysis Grid for Environments Linked to Obesity was used to categorize PA factors. Study findings were centered on the concept of safety, facilities, parental restriction, friends, cultural traits, media, community cohesiveness, and weather. The central theme was "feeling unsafe" when being outdoors. To promote PA behavior, provision of PA facilities needs to be supported by other programs that build on peer support, crime prevention, and traffic safety, together with other educational campaigns.
Efforts to model the human upper respiratory system have undergone many phases. Geometrical proximity to the realistic shape has been the subject of many research projects. In this study, three different geometries of the trachea and main bronchus were modelled, which were reconstructed from computed tomography (CT) scan images. The geometrical variations were named realistic, simplified and oversimplified. Realistic refers to the lifelike image taken from digital imaging and communications in medicine format CT scan images, simplified refers to the reconstructed image based on natural images without realistic details pertaining to the rough surfaces, and oversimplified describes the straight wall geometry of the airway. The characteristics of steady state flows with different flow rates were investigated, simulating three varied physical activities and passing through each model. The results agree with previous studies where simplified models are sufficient for providing comparable results for airflow in human airways. This work further suggests that, under most exercise conditions, the idealised oversimplified model is not favourable for simulating either airflow regimes or airflow with particle depositions. However, in terms of immediate analysis for the prediction of abnormalities of various dimensions of human airways, the oversimplified techniques may be used.
Despite the advancement of cardiac imaging technologies, these have traditionally been limited to global geometrical measurements. Computational fluid dynamics (CFD) has emerged as a reliable tool that provides flow field information and other variables essential for the assessment of the cardiac function. Extensive studies have shown that vortex formation and propagation during the filling phase acts as a promising indicator for the diagnosis of the cardiac health condition. Proper setting of the boundary conditions is crucial in a CFD study as they are important determinants, that affect the simulation results. In this article, the effect of different transmitral velocity profiles (parabolic and uniform profile) on the vortex formation patterns during diastole was studied in a ventricle with dilated cardiomyopathy (DCM). The resulting vortex evolution pattern using the uniform inlet velocity profile agreed with that reported in the literature, which revealed an increase in thrombus risk in a ventricle with DCM. However the application of a parabolic velocity profile at the inlet yields a deviated vortical flow pattern and overestimates the propagation velocity of the vortex ring towards the apex of the ventricle. This study highlighted that uniform inlet velocity profile should be applied in the study of the filling dynamics in a left ventricle because it produces results closer to that observed experimentally.
Hypertension is a common comorbidity among diabetic patients. This study aimed to determine blood pressure (BP) control among hypertensive patients with and without diabetes. This was a cross-sectional study in 6 public primary care clinics in Wilayah Persekutuan, Malaysia. Hypertensive patients aged ≥18 years and attending the clinics were selected via systematic random sampling. The BP control target was defined as <130/80 mm Hg for diabetic patients and <140/90 mm Hg for nondiabetic patients. A total of 1107 hypertensive patients participated in this study and 540 (48.7%) had diabetes. About one fourth (24.3%) of the hypertensive patients with diabetes achieved BP control target, compared with 60.1% patients without diabetes (P < .001). Being diabetic and on ≥2 antihypertensive treatments were associated with poor BP control. Attention needs to be given to these groups of patients when managing patients with hypertension.
This study examines the inequality of the use of skilled delivery assistance by the rural women of Bangladesh using the 2007 Bangladesh Demographic and Health Survey data. Simple cross-tabulation and univariate and multivariate statistical analyses were employed in the study. Overall, 56.1% of the women received at least one antenatal care visit, whereas only 13.2% births were assisted by skilled personnel. Findings revealed apparent inequality in using skilled delivery assistance by socioeconomic strata. Birth order, women's education, religion, wealth index, region and antenatal care are important determinants of seeking skilled assistance. To ensure safe motherhood initiative, government should pay special attention to reduce inequality in seeking skilled delivery assistance. A strong focus on community-based and regional interventions is important in order to increase the utilization of safe maternal health care services in rural Bangladesh.
This study examines the factors that influence institutional delivery among women in Bangladesh extracting data from 2007 Bangladesh Demographic and Health Survey. We employed both bivariate and multivariate statistical analyses in this study. Findings revealed that, only 14.7% of the women went for institutional delivery and 28.8% births were delivered by trained birth attendance. The multivariate logistic regression analysis yielded quantitatively important and reliable estimates of facility delivery. The likelihood of institutional delivery was significantly higher for first-order pregnancy, couples' higher education, the richest, higher autonomy, TV ownership, non-Muslims, who received antenatal care services, pregnancy complications, and urban residents. Government should ensure quality of care, easy accessibility, and availability of all facilities free of cost in the public medical institutions. Women should be informed regarding the long-term benefit of institutional delivery through information, education, and communication program.
A prospective cross-sectional study was conducted at 3 government hospitals over 6 months to evaluate the confidence level of medical officers (MOs) to perform clinical procedure in nonspecialist government hospitals in Penang. An anonymous self-administered questionnaire in English was designed based on the elective and emergency procedures stated in the houseman training logbook. The questionnaire was distributed to the MOs from Penang State Health Department through the respective hospital directors and returned to Penang State Health Department on completion. The results showed that there was statistically significant difference between those who had undergone 12 months and 24 months as houseman in performing both elective and emergency procedures. MOs who had spent 24 months as housemen expressed higher confidence level than those who had only 12 months of experience. We also found that the confidence level was statistically and significantly influenced by visiting specialist and working together with cooperative experienced paramedics.
This study examines the rate of decline of estimated glomerular filtration rate (eGFR) over a 10-year period and the associated risk factors in type 2 diabetes mellitus (T2DM) patients. Medical records of T2DM patients were randomly selected. The rate of fall in eGFR (simplified modification of diet in renal disease formula) was used as a measure of decline. Univariate and multivariate analysis were performed to determine the factors associated with decline of kidney function. A total of 504 patients were selected. Mean age was 57.8 ± 9 years; 65.3% were females. The mean decline rate of eGFR was 0.89 ± 2.16 mL/min/1.73 m(2)/y. Baseline proteinuria, glycosylated hemoglobin level, duration of T2DM, and Malay race were associated with faster decline in eGFR. The expected greater deterioration in kidney function in this cohort was not seen. Treatment of proteinuria and glycemia should be optimized early to retard the decline in kidney function in patients with T2DM.

Iodine deficiency during pregnancy and lactation may adversely affect fetal and infant development. Two initiatives were introduced in New Zealand to prevent deficiency: (1) mandatory fortification of bread with iodised salt; and (2) provision of a subsidised iodine supplement (150 μg) for all pregnant and breastfeeding women. The aim of this study was to assess iodine intake and status among a self-selecting sample of pregnant and lactating women in Palmerston North, both before and after the two initiatives. Pregnant and breastfeeding women were recruited before (n = 25 and 32; 2009) and after (n = 34 and 36; 2011) the initiatives. Iodine concentration was determined in 24-h urine and breast milk samples using inductively-coupled plasma mass spectrometry. Use of supplements and salt, knowledge of iodine deficiency, and awareness of the initiatives were determined by questionnaire. Median urine iodine concentration (UIC) was higher in 2011 compared with 2009 for both pregnant (85 and 47 μg L(-1) ) and breastfeeding (74 and 34 μg L(-1) ) participants; median UIC were below the cut-offs for adequate iodine status. However, in 2011, the estimated daily iodine intake during pregnancy was 217 μg day(-1) ; 74% of women achieved the Estimated Average Requirement. Knowledge of the initiatives was low, only 28-56% were aware of the need for iodine supplements and only 15-22% were aware of the mandatory addition of iodised salt to bread. Despite initiatives, UIC of these women indicates iodine deficiency, however, dietary intakes appear adequate. Ongoing surveillance of supplement use and iodine status among pregnant and lactating women throughout New Zealand is needed to fully assess the efficacy of the initiatives. Alternative strategies may require evaluation to ensure all women have adequate iodine during pregnancy and breastfeeding.
The study evaluated whether a pharmaceutical care intervention can result in better understanding about hypertension, increase medication adherence to antihypertensive therapy and improve overall health-related quality of life.
INTRODUCTION: The present study investigated the relationship between psychological symptoms and psychosocial function and the role of relevant sociodemographic data and antipsychotic use in the prediction of psychosocial function among multiracial schizophrenia outpatients in Malaysia.
METHODS: A total of 223 participants were recruited in this cross-sectional study conducted from December 2010 to April 2011. Psychological symptoms were assessed using the Positive and Negative Syndrome Scale whilst the psychosocial function was assessed using the Personal and Social Performance scale. Sociodemographic and treatment variables were gathered through interview or review of the medical records.
RESULTS: All dimensions of psychosocial functions were inversely correlated with Positive and Negative Syndrome Scale sub-domains. Only the disorganization sub-domain significantly predicts all dimensions of psychosocial function. For social data, body mass index and employment status were significant predictors of all dimensions of psychosocial functions. Typical antipsychotics significantly predict social function negatively as compared to sulpiride (β = -0.152, P = 0.028).
DISCUSSION: We found that the relationship between psychological symptoms and psychosocial functions were relatively consistent with the findings from the Caucasian population. Additionally, disorganization was the only significant predictor of all dimensions of psychosocial functions. This further emphasized the importance of cognition in psychosocial function. The roles of sulpiride, body mass index and employment status as predictors of psychosocial function were also discussed.

Psoriasis is a chronic dermatological disorder that has a negative impact on quality of life (QoL). This hospital-based cross-sectional study determined factors associated with health-related QoL (HRQoL) impairment in adult psoriasis patients. HRQoL was assessed using the Dermatology Life Quality Index (DLQI). Disease severity was assessed using the Psoriasis Area and Severity Index (PASI). A total of 223 patients, aged 18 to 83 years, were recruited. For 67 (30%) patients, psoriasis had very large to extremely large effect on their life (DLQI score = 11-30). The median DLQI score was 7 (interquartile range = 7). Factors significantly associated with severe impact on HRQoL (DLQI ≥ 10) were disease severity, single status, working status, sports activities, nail dystrophy, exposed area involvement, itch, disturbed sleep, stress, and infection. The factor predictive of severe impact of psoriasis on HRQoL was disease severity. A holistic approach in the management, including psychosocial issues, is absolutely crucial for the optimal care of psoriasis patients.
