Healthcare workers (HCWs) are at risk of contracting coronavirus disease-2019 (COVID-19) in their workplace. Infection prevention guidelines and standard operating procedures were introduced to reduce risk of exposure and prevent transmission. Safe practices during interaction with patients with COVID-19 are crucial for infection prevention and control (IPC). This study aimed to assess HCWs' compliance to IPC and to determine its association with sociodemographic and organizational factors. A cross-sectional study was conducted between March and April 2021 at public healthcare facilities in the east coast of Peninsular Malaysia. HCWs who were involved with COVID-19-related works were invited to participate in the online survey. The questionnaire was adapted from the World Health Organization (WHO) Interim Guidance: WHO Risk Assessment and Management of Exposure of Healthcare Workers in the Context of COVID-19. Respondents were categorized as compliant or non-compliant to IPC. A total of 600 HCWs involved in COVID-19-related works participated in the survey. Most of them (63.7%) were compliant to IPC as they responded to all items as "always, as recommended" during interaction with patients with COVID-19. The multivariate analysis showed that non-compliance was significantly associated with working in the emergency department (AOR = 3.16; 95% CI = 1.07-9.31), working as laboratory personnel (AOR = 15.13; 95% CI = 1.36-168.44), health attendant (AOR = 4.42; 95% CI = 1.74-11.24), and others (AOR = 3.63; 95% CI = 1.1-12.01), as well as work experience of more than 10 years (AOR = 4.71; 95% CI = 1.28-17.27). The odds of non-compliance among respondents without adequate new norms and personal protective equipment training were 2.02 (95% CI = 1.08-3.81) more than those with adequate training. Although most of the respondents complied to IPC protocols, compliance status differed according to department, work category, and years of service. Ensuring adequate training that will hopefully lead to behavioral change is crucial to prevent breach in IPC and thus minimize the risk of exposure to and transmission of COVID-19 in healthcare facilities.
A cross sectional study was carried out to evaluate the extent of occupational health problems focusing on some aspects of musculoskeletal symptoms among batik workers in Kelantan, Malaysia. The workers selected must have been in that industry for at least one year. Using cluster sampling, 202 workers were selected from 21 factories. More than half (60.2%) of the workers had been troubled with musculoskeletal symptoms at work. The most common symptoms were pain over the shoulders (41.0%), lower back (34.4%) and ankle (34.4%). Duration of employment, younger age group, prolonged standing and awkward working task were among contributing factors. It is therefore necessary to improve on both ergonomic and psychosocial environments of batik workers in order to prevent these musculoskeletal symptoms.
INTRODUCTION: Due to globalization and changes in the health care delivery system, there has been a gradual change in the attitude of the medical community as well as the lay public toward greater acceptance of euthanasia as an option for terminally ill and dying patients. Physicians in developing countries come across situations where such issues are raised with increasing frequency. As euthanasia has gained world-wide prominence, the objectives of our study therefore were to explore the attitude of physicians and chronically ill patients toward euthanasia and related issues. Concomitantly, we wanted to ascertain the frequency of requests for assistance in active euthanasia.
MATERIALS AND METHODS: Questionnaire based survey among consenting patients and physicians.
RESULTS: The majority of our physicians and patients did not support active euthanasia or physician-assisted suicide (EAS), no matter what the circumstances may be P < 0.001. Both opposed to its legalization P < 0.001. Just 15% of physicians reported that they were asked by patients for assistance in dying. Both physicians 29.2% and patients 61.5% were in favor of withdrawing or withholding life-sustaining treatment to a patient with no chances of survival. Among patients no significant differences were observed for age, marital status, or underlying health status.
CONCLUSIONS: A significant percentage of surveyed respondents were against EAS or its legalization. Patient views were primarily determined by religious beliefs rather than the disease severity. More debates on the matter are crucial in the ever-evolving world of clinical medicine.

BACKGROUND: The prevalence of self-neglect among the elderly is expected to rise with a rapid increase in the growth of the older population. However, self-neglect in the elderly and the factors related to it are not fully understood due to the limited research in the area, lack of consensus in the definition of the concept, and limited instrumentation. The purpose of this study was to investigate the relationship between selected socio-demographic factors on self-care and self-neglect among older persons living in the community.
MATERIALS AND METHODS: A cross-sectional survey design with cluster sampling was adopted for the study. Data were gathered from 201 older persons aged 60 years and over in the state of Selangor, Malaysia, through face-to-face interviews in their homes with a team of trained enumerators. A new instrument was developed to measure self-neglect.
RESULTS: The internal consistency of the new instrument showed a reliability of 0.90. A significant bivariate relationship was noted between self-care and self-neglect. The socio-demographic factors were also reported between self-care and self-neglect.
CONCLUSIONS: The new instrument of elder self-neglect (ESN) could be used to measure self-neglect in a community dwelling. The need to increase the self-care skills and the capacity of self-care among older adults is crucial in order to reduce self-neglect and enhance their well-being.

All around the world, there is growing evidence of the association between psoriasis and comorbidities which increase the risk of cardiovascular disease. This study aims to determine the prevalence of various comorbidities among adult psoriasis patients in Malaysia. A cross-sectional study was conducted among patients in the Malaysian Psoriasis Registry from January 2007 to December 2008. A total of 2,267 adult patients with psoriasis from 13 dermatology centers were included. Prevalence of various comorbidities were: hypertension 25.9%, diabetes mellitus 17.7 %, dyslipidaemia 17.8%, overweight 33.2%, obesity 20.7%, ischaemic heart disease 5.8% and cerebrovascular disease 1.4%. These comorbidities were more prevalent in patients with psoriasis of late-onset and longer duration. Active screening of these comorbidities in all adult psoriasis patients is recommended.
The Osteoporosis Self-Assessment Tool for Asians (OSTA) score has been developed to identify women at risk of osteoporosis. It can be used as a screening tool for patients at risk who would benefit from bone mineral density measurement and treatment. It was developed based on data from eight countries including Malaysia. However, most subjects were of Chinese (59%). This study evaluated the performance of OSTA among 152 post-menopausal Malay women. OSTA score calculation and DEXA scan were performed. Our results showed that the OSTA score is a good predictor of patients at risk of osteoporosis based on BMD measurements at the proximal femur. Instrument sensitivity was 87.5%, specificity was 95.8%, positive predictive value (PPV) was 0.538, negative predictive value (NPV) was 0.993, and the area under the receiver operating characteristic curve (ROC) was 0.895. We conclude that use of the OSTA score in postmenopausal Malay women is effective and has adequate sensitivity and specificity.
Measurement of quality of life among prostate cancer patients helps the health care providers to understand the impact of the disease in the patients' own perspective. The main aim of this study is to measure the quality of life among prostate cancer patients at University Malaya Medical Center (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and to ascertain the association factors for physical coefficient summary (PCS) and mental coefficient summary (MCS). A hospital based, cross sectional study using the Short Form-36 (SF-36) questionnaire was conducted over a period of 6 months. A total of 193 respondents were recruited. Their total quality of life score was 70.1± 14.7 and the PCS score was lower compared to MCS. The factors associated for PCS were: age, living partner, renal problem, urinary problem of intermittency, dysuria and hematuria. Factors associated for MCS were: age, living partner, renal problem, presenting prostatic specific antigen and urinary problem of intermittency and dysuria. Our prostate cancer patients had moderate quality of life in the physical health components but their mental health was less affected.
A survey was carried out to determine the prevalence of bronchial asthma and their contributing risk factors among Orang Asli subgroups living in Malaysia using IUATLD questionnaire and spirometry without being discriminatory towards age or gender. Of the 1171 distributed questionnaires, 716 (61.1%) comprising of 62.7% Semai Pahang, 51.3% Temiar, 74.2% Mah Meri, 65.6% Semai Perak, 53.6% Temuan, 53.8% Semelai, 61.1% Jakun and 67.4% Orang Kuala subgroups completed their questionnaire and were included in the data analysis. Participants comprised 549 (76.7%) children and 167 (23.3%) adults, age between 1 to 83 years old, 304 (42.5%) males and 412 (57.5%) females. The overall prevalence of bronchial asthma was 1.4% of which 1.5% was children, 1.3% adults, 1.0% male and 1.7% female, respectively. Of the 8 subgroups surveyed, 5 out of 10 confirmed asthma cases were Semai Pahang, followed by 3 cases among Mah Meri, and one case each among Temuan and Semai Perak subgroups, respectively. This study also demonstrated that the prevalence of self-reported and confirmed bronchial asthma tend to be higher among those who had close contact with pets, smoking individuals and among those who had a family history of asthma.
BACKGROUND: Aspirin use is known to reduce the recurrence of stroke. However, the clinical response to aspirin has been mixed. The rate of stroke recurrence whilst on aspirin treatment is still unacceptably high. A plausible explanation for this may be resistance to the effects of aspirin. The causes of aspirin resistance are manifold and multi-factorial. We conducted a study to investigate the prevalence rate of biochemical aspirin resistance in a cohort of aspirin-naïve stroke patients. We also sought to determine the inherent factors that may predispose towards the development of aspirin resistance.
METHOD: This was a cross-sectional, observational study conducted on patients admitted to our centre with an acute stroke who were aspirin-naïve. The diagnosis of an acute stroke was confirmed by clinical history and brain imaging. Fifty consecutive patients were prospectively enrolled. Socio-demographic data were collected and baseline blood investigations were performed. Patients were tested for biochemical aspirin resistance using Multiplate platelet analyser (Dynabyte, Munich, Germany) after 5 doses of aspirin, corresponding to a total dose of 900 mg.
RESULTS: The median age of patients was 65.5 years and 54 % of patients were female. There were 11 smokers; of these 10 were male. Twenty-six (52 %) patients were Chinese, 21 (41 %) were Malay and 3 (6.0 %) were Indian. Aspirin resistance was present in 14 % of our patients. There was an inverse relationship between the presence of aspirin resistance and plasma HDL levels (r = -0.394; p = 0.005). There was no relationship observed between aspirin resistance and total cholesterol, triglycerides, LDL, HbA1c, ALT, ALP, urea and creatinine levels. There were no significant differences in demographic profiles or smoking status between the aspirin resistant and non-aspirin resistant groups. We did not find any link between ethnicity and aspirin resistance.
CONCLUSIONS: Our results indicate that a lower HDL level is associated with biochemical aspirin resistance. This may increase platelet aggregation and consequently increase the risk of a recurrent stroke. The clinical implications for aspirin resistance are far reaching. Any evidence that correctable factors may negatively influence the action of aspirin warrants further investigation. The prevalence rate of biochemical aspirin resistance in our study is comparable to the findings in other studies performed in an Asian population. Further research is required to determine how our findings translate into clinical aspirin resistance and stroke recurrence.

This cross-sectional study aimed to determine the prevalence, frequency, and intensity of parent-reported pain among non-verbal children with cerebral palsy (CP) and explore associations with medical, demographic, and parental psychosocial factors.
Continuous nursing education (CNE) courses delivered through e-learning is believed to be an effective mode of learning for nurses. Implementation of e-learning modules requires pre-assessment of infrastructure and learners' characteristics. Understanding the learners' needs and their perspectives would facilitate effective e-learning delivery by addressing the underlying issues and providing necessary support to learners.
Chronic periodontitis (CP) is a global public health issue. Studies have suggested CP could be linked to obesity due to their similar pathophysiological pathway. The aim of this study is to determine the prevalence of CP and to assess the predictors for CP among the obese Malaysian population.
METHODS: This is a cross-sectional study on obese participants. Obesity is defined as an individual who has Body Mass Index (BMI) ≥ 27.5 kg/m(2). A convenience sampling method was used. A total of 165 paricipants were recruited. This study involved answering questionnaires, obtaining biometric and clinical measurements of Visible plaque index (VPI), Gingival bleeding index (GBI), Probing pocket depth (PPD) and Clinical attachment loss (CAL). Data analysis was carried out using SPSS statistical software (SPSS Inc., version 20, US).
RESULTS: A total of 165 participants; 67 (40.6%) males and 98 (59.4%) females participated in the study. Mean age of the participants was 43.9 (± 8.9). The prevalence of CP among the obese population was found to be 73.9%. Out of this, 43 and 55% were categorised as moderate and severe CP respectively. Around 64% of participants had sites with CAL ≥ 4 mm and participants with sites with PPD ≥ 4 mm were reported to be 25%. Around 83% of the participants had sites with GBI ≥ 30 and 92% of participants had sites with VPI ≥ 20%. GBI and VPI were found to have significantly higher odds for CP.
CONCLUSION: Prevalence of CP was high among obese Malaysians. GBI and VPI were potential predictors for CP in this obese population.
OBJECTIVE: The aim of this study was to compare the use of semi-automated (Medax Velox 2; Poggio Rusco, Italy) and automated (Bard Magnum Biopsy Instrument; Covington, GA, USA) core biopsy needles, for ultrasound guided breast biopsy.
MATERIALS AND METHODS: A 14G semi-automatic spring loaded core biopsy needle with a 22-mm-throw (Medax Velox 2; Poggio Rusco, Italy) and 14-gauge automated needle device with a 22-mm-throw biopsy gun (Bard-Magnum Biopsy Instrument, Covington, GA, USA) were used for breast biopsies under ultrasound guidance on alternate months during the study period between July 2009 and May 2011. One hundred and sixty lesions were biopsied and specimens were sent for histological evaluation.
RESULTS: The automated needle obtained a higher number of histology reports at 84% (67/80) as compared with the semiautomated needle at 60% (48/80) (Fisher exact test, p value=0.023). Inadequate samples with the automated needle were much less at 9% (7/60) than with the semiautomated needle at 23% (18/60) (Fisher exact test, p value=0.028). The semi-automated needle showed slightly less fragmented samples. However, the number of fragmented samples with definitive diagnosis was slightly higher with the automated compared with the semiautomated needle, at 16% (13/80) and 13% (10/80) respectively. Compared with histology of 29 lesions that were excised, the semi-automated needle had higher sensitivity (100%) but lower specificity (75%) and accuracy (90%) compared with the automated needle (88% sensitivity, 100% specificity, 95% accuracy).
CONCLUSION: Definitive diagnosis from the study samples slightly favours the use of automated core biopsy needle as compared to semi-automated core biopsy needle.

Hypertension is the leading cardiovascular risk factor globally as well as in Malaysia. This study aimed to estimate the prevalence, awareness, treatment, control and the socio demographic determinants of hypertension among Malaysian adults.
Although diets with high energy density are associated with increased risk of overweight and obesity, it is not known whether such diets are associated with undernutrition. This study assessed the relationship between dietary energy density (ED) and nutritional status of 745 urban 1- to 10-year-old children. Dietary intakes were obtained using food recall and record for two days. Dietary energy density was based on food and caloric beverages. Higher dietary ED was associated with lower intakes of carbohydrate, sugar, vitamins C and D, and calcium but higher fat, fiber, iron, and folate intakes. While intakes of fruits and milk/dairy products decreased, meat, fish, and legume intakes increased with higher dietary ED. Stunting, but not other growth problems, was associated with higher dietary ED. Future studies should confirm the cause-and-effect relationship between higher dietary ED and stunting.
The aim of this study was to examine the relationship between self-reported leisure time physical inactivity frequency and sedentary behaviour and lifestyle correlates among school children in the Association of Southeast Asian Nations (ASEAN) region. The analysis included 30,284 school children aged 13-15 years from seven ASEAN countries that participated in the Global School-based Student Health Survey (GSHS) between 2007 and 2013. The measure asked about overall physical activity, walking or biking to school, and on time spent sitting. Overall, the prevalence of physical inactivity was 80.4%, ranging from 74.8% in Myanmar to 90.7% in Cambodia and sedentary behaviour 33.0%, ranging from 10.5% in Cambodia and Myanmar to 42.7% in Malaysia. In multivariate logistic regression, not walking or biking to school, not attending physical education classes, inadequate vegetable consumption and lack of protective factors (peer and parental or guardian support) were associated with physical inactivity, and older age (14 and 15 years old), coming from an upper middle income country, being overweight or obese, attending physical education classes, alcohol use, loneliness, peer support and lack of parental or guardian supervision were associated with sedentary behaviour. In boys, lower socioeconomic status (in the form of having experienced hunger) and coming from a low income or lower middle income country were additionally associated with physical inactivity, and in girls, higher socioeconomic status, not walking or biking to school and being bullied were additionally associated with sedentary behaviour. In conclusion, a very high prevalence of leisure physical inactivity and sedentary behaviour among school going adolescents in ASEAN was found and several factors identified that may inform physical activity promotion programmes in school-going adolescents in ASEAN.

OBJECTIVE: To determine the correlation between central venous pressure (CVP) measured by conventional central venous access and ultrasonographic measurement of internal jugular vein (IJV) height and inferior vena cava (IVC) diameter.
METHODS: A prospective, cross-sectional, convenience sampling observational study.
RESULTS: 25 patients from the Emergency Department (ED) Universiti Kebangsaan Malaysia Medical Centre (UKMMC) were studied between 1st March and 30th April 2013. The median age was 63 years (95% CI 54-67). There was a significant correlation between IJV height and CVP using central venous access (r=0.64 p<0.001). Correlation between IVC diameter in end expiration and CVP was 0.74 (p<0.001). An IJV height measurement >8cm predicted a CVP >8cm H2O (sensitivity 71.4%, specificity of 83.3%).
CONCLUSION: Measurement of IJV height and IVC diameter by ultrasonography correlates well with invasive CVP and is useful for the assessment of volume status in critically ill patients in the ED.

INTRODUCTION: Patients suffering from diabetes mellitus (DM) frequently present with infected diabetic foot ulcers (DFU). This study was done to record the anatomical site and the grade of ulcers according to Wagner's classification and to culture the microorganisms from the ulcers and determine their antibiotic sensitivity.
MATERIALS AND METHODS: Prospective study was conducted on 77 diabetic patients who were admitted with DFU from June until December 2011. Patients with end stage renal failure, those who had previous vascular surgery on the involved limb, or hyperbaric oxygen or maggot therapy for the ulcers, or had unrelated skin diseases around the involved foot were excluded from the study. Specimens for culture were obtained by a sterile swab stick or tissue sample was taken from the wound with sterile surgical instruments.
RESULTS: Wagner's grade III and IV ulcers were most common. Majority of the ulcers involved toes (48%). Gram negative microorganisms were predominantly isolated (71.1%). Gram positive microorganisms were less frequently cultured (27.7%). Fungus was cultured from one sample (1.2%). Gram negative microorganisms were sensitive to aminoglycosides, cephalosporins or β-lactamase inhibitors. More than 40% were resistant to ampicillin. Gram positive microorganisms were sensitive to cloxacillin. MRSA were sensitive to vancomycin.
CONCLUSION: Empirical use of antibiotics should be curtailed to prevent development of drug resistant strains of microorganisms and MRSA. We suggest use of antiseptic solutions to clean the ulcers until antibiotic sensitivity report is available. Results of our altered treatment regimen we plan to publish in a later study.
