RESUMEN
Nationally-representative evidence is limited on factors affecting uptake of cataract surgery in Malaysia. We found the prevalence of cataract among older persons to be 26.8%. The two most common barriers were 'need not felt' (43.5%) and 'fear of surgery or poor result' (16.2%). Reluctance for surgical intervention was greater outside the Central zone.

INTRODUCTION: The implications of work-related stress among manufacturing workers were often unrecognised. The purpose of this study is to determine the effectiveness of the workplace health promotion (WHP) program in reducing depression, anxiety, and stress levels, as well as improving the overall quality of life among Malaysian manufacturing workers. METHODS: The study used a randomised controlled trial (RCT) design and included 88 employees from a food and beverage manufacturing factory in Klang Valley, Malaysia. The intervention group received a comprehensive WHP program based on organisational and individual stress management programs that included (i) healthy mental health module, (ii) anxiety management technique, (iii) mindfulness for stress and (iv) stress at work. The module was delivered through the Occupational Stress Management Course and Employee Assistance Program. The control group received no further intervention other than a general brochure on stress. The study period consisted of an intervention period of 3 months followed by a post-intervention period of 3 months. Measurements were recorded at baseline and at 3 month post-intervention. Outcome measures included the self-perceived depression, anxiety, and stress (DASS-21), participant's quality of life (WHOQOL), coping skills (COPE-28) and job characteristics (JCQ). RESULTS: The intervention group demonstrated a significant reduction in self-perceived stress, anxiety, and depression scores three months post intervention (p ≤ 0.001). All domains of health-related quality of life and coping skills related to social support and problem-solving were significantly improved in the intervention group following the intervention (p < 0.001). In the control group, no significant changes were observed in all the parameters. CONCLUSION: WHP program shows promising results in improving mental health status, quality of life and coping skills among the manufacturing workers.

BACKGROUND: Hospitals are vulnerable to COVID-19 outbreaks. Intrahospital transmission of the disease is a threat to the healthcare systems as it increases morbidity and mortality among patients. It is imperative to deepen our understanding of transmission events in hospital-associated cases of COVID-19 for timely implementation of infection prevention and control measures in the hospital in avoiding future outbreaks. We examined the use of epidemiological case investigation combined with whole genome sequencing of cases to investigate and manage a hospital-associated cluster of COVID-19 cases. METHODS: An epidemiological investigation was conducted in a University Hospital in Malaysia from 23 March to 22 April 2020. Contact tracing, risk assessment, testing, symptom surveillance, and outbreak management were conducted following the diagnosis of a healthcare worker with SARS-CoV-2 by real-time PCR. These findings were complemented by whole genome sequencing analysis of a subset of positive cases. RESULTS: The index case was symptomatic but did not fulfill the initial epidemiological criteria for routine screening. Contact tracing suggested epidemiological linkages of 38 cases with COVID-19. Phylogenetic analysis excluded four of these cases. This cluster included 34 cases comprising ten healthcare worker-cases, nine patient-cases, and 15 community-cases. The epidemic curve demonstrated initial intrahospital transmission that propagated into the community. The estimated median incubation period was 4.7 days (95% CI: 3.5-6.4), and the serial interval was 5.3 days (95% CI: 4.3-6.5). CONCLUSION: The study demonstrated the contribution of integrating epidemiological investigation and whole genome sequencing in understanding disease transmission in the hospital setting. Contact tracing, risk assessment, testing, and symptom surveillance remain imperative in resource-limited settings to identify and isolate cases, thereby controlling COVID-19 outbreaks. The use of whole genome sequencing complements field investigation findings in clarifying transmission networks. The safety of a hospital population during this COVID-19 pandemic may be secured with a multidisciplinary approach, good infection control measures, effective preparedness and response plan, and individual-level compliance among the hospital population.

This qualitative study explores the medical radiation workers' (MRWs) beliefs with the support of the theory of planned behaviour's constructs regarding the use of personal dosimeters in order to identify the facilitating factors and barriers to practising good personal dose monitoring. The exploration was conducted through semi-structured face-to-face interviews with 63 MRWs from the public, private, and university hospitals. Belief statements from the informants were organized under the behavioural, normative, and control belief, as guided by the theory. A thematic analysis found that a majority of informants acknowledged the benefits of using dosimeters. However, several factors influenced the actual usage. The informants were hesitant to use the dosimeter as the loss of the device involved an expensive penalty. They also mentioned that delayed dosimeter supplies due to late budget approval in the hospitals and some other reasons had got them disconnected from the monitoring system. The workers' attitudes and social norms highly induced their dosimeter usage as well; some perceived themselves to be at low risk for high exposure to radiation, and forgetfulness was also mentioned as a reason for lack of adherence. Device physical factor influenced low dosimeter use too. This study highlighted some unique findings in Asian settings. A better understanding of the underlying reasons for the lack of dosimeter use will be useful in developing strategies to increase good practices in personal radiation monitoring.

BACKGROUND: Research suggests that junior doctors often experience workplace bullying, which may have adverse impacts on medical training and delivery of quality healthcare. However, evidence among local population has not been established. The present study aims to examine the prevalence of workplace bullying among Malaysian junior doctors and explore its associated sociodemographic and employment factors. METHODS: A multicentre cross-sectional study was conducted in 12 government hospitals accredited for housemanship training within the central zone of Malaysia. The study included a total of 1,074 house officers who had been working for at least 6 months in various housemanship rotations. The Negative Acts Questionnaire-Revised (NAQ-R) was used to examine workplace bullying. RESULTS: The 6-month prevalence of workplace bullying among study participants was 13%. Work-related bullying such as 'being ordered to do work below your level of competence', person-related bullying such as 'being humiliated or ridiculed in connection with your work', and physically intimidating bullying such as 'being shouted at or being the target of spontaneous anger' were commonly reported by study participants. Medical officers were reported to be the commonest perpetrators of negative actions at the workplace. Study participants who graduated from Eastern European medical schools (adjusted odds ratio [AOR] 2.27; 95% confidence interval [CI]: 1.27, 4.07) and worked in surgical-based rotation (AOR 1.83; 95% CI: 1.13, 2.97) had higher odds of bullying compared to those who graduated from local medical schools and worked in medical-based rotation, whereas study participants with good English proficiency (AOR 0.14; 95% CI: 0.02, 0.94) had lower odds of bullying compared to those with poor English proficiency. CONCLUSION: The present study shows that workplace bullying is prevalent among Malaysian junior doctors. Considering the gravity of its consequences, impactful strategies should be developed and implemented promptly in order to tackle this serious occupational hazard.
RESUMEN
INTRODUCTION: The reporting of Coronavirus Disease 19 (COVID-19) mortality among healthcare workers highlights their vulnerability in managing the COVID-19 pandemic. Some low- and middle-income countries have highlighted the challenges with COVID-19 testing, such as inadequate capacity, untrained laboratory personnel, and inadequate funding. This article describes the components and implementation of a healthcare worker surveillance programme in a designated COVID-19 teaching hospital in Malaysia. In addition, the distribution and characteristics of healthcare workers placed under surveillance are described. MATERIAL AND METHODS: A COVID-19 healthcare worker surveillance programme was implemented in University Malaya Medical Centre. The programme involved four teams: contact tracing, risk assessment, surveillance and outbreak investigation. Daily symptom surveillance was conducted over fourteen days for healthcare workers who were assessed to have low-, moderate- and high-risk of contracting COVID-19. A cross-sectional analysis was conducted for data collected over 24 weeks, from the 6th of March 2020 to the 20th of August 2020. RESULTS: A total of 1,174 healthcare workers were placed under surveillance. The majority were females (71.6%), aged between 25 and 34 years old (64.7%), were nursing staff (46.9%) and had no comorbidities (88.8%). A total of 70.9% were categorised as low-risk, 25.7% were moderate-risk, and 3.4% were at high risk of contracting COVID-19. One-third (35.2%) were symptomatic, with the sore throat (23.6%), cough (19.8%) and fever (5.0%) being the most commonly reported symptoms. A total of 17 healthcare workers tested positive for COVID-19, with a prevalence of 0.3% among all the healthcare workers. Risk category and presence of symptoms were associated with a positive COVID-19 test (p<0.001). Fever (p<0.001), cough (p = 0.003), shortness of breath (p = 0.015) and sore throat (p = 0.002) were associated with case positivity. CONCLUSION: COVID-19 symptom surveillance and risk-based assessment have merits to be included in a healthcare worker surveillance programme to safeguard the health of the workforce.

Electronic cigarettes (e-cigarettes) have rapidly increased in popularity within the last 2 years in Malaysia. The study aims to understand the association between e-cigarette use behaviors and salivary cotinine (a CYP2AA metabolite of nicotine) concentration to inform the development of future e-cigarette control policies. A convenience sample of saliva from 144 e-cigarette users was obtained between November and December 2015. The study participants used refill liquid containing between 0 and 12 mg/ml of nicotine. The overall median cotinine concentration of the study participants was 81.1 ng/ml (interquartile range = 8.5-195.8). Among the zero-nicotine and single e-cigarette users, the median cotinine level was 51.1 (interquartile range = 8.20-125.35) ng/ml. Factors significantly associated with a higher salivary cotinine concentration were dual use of e-cigarettes and tobacco cigarettes, regular and daily e-cigarette use, a longer duration of e-cigarette use, using a higher amount of e-liquid, and a shorter duration to finish a refill. Multivariate analysis revealed that e-cigarette use of 1-6 and 6-12 months (but not 1 month and below) was significantly associated with a higher cotinine concentration. Cotinine found in zero-nicotine e-liquids implies the importance of stringent regulatory governance for the consistency of labeled nicotine content of e-cigarette liquid in the market. Zero-nicotine e-cigarette users should also be informed of the likelihood of environmental exposure to tobacco smoke. Future studies conducted on larger samples are warranted to validate the association between duration of e-cigarette use and salivary cotinine concentration as well as to investigate underlying mechanisms.

Previous studies have indicated that junior doctors commonly experience workplace bullying and that it may adversely impact medical training and delivery of quality healthcare. Yet, evidence on the precursors of bullying among them remains elusive. Drawing on the individual-disposition hypothesis, the present paper examined the relationships of negative affect, personality and self-esteem with workplace bullying among junior doctors. Multilevel analysis of a universal sample (n = 1074) of junior doctors working in the central zone of Malaysia using mixed effects logistic regression was performed. The results indicate that participants with moderate (AOR 4.40, 95% CI 2.20-8.77) and high degree (AOR 13.69, 95% CI 6.46-29.02) of negative affect as well as high degree of neuroticism (AOR 2.99, 95% CI 1.71-5.21) have higher odds of being bullied compared to their counterparts. The findings present evidence that individual traits are associated with junior doctors' exposure to bullying. While victim blaming should be avoided, this suggest that antibullying measures with an interpersonal focus should be considered when developing antibullying initiatives targeted at junior doctors. This includes primary intervention such as cognitive training, secondary interventions such as resource enhancement building and conflict management skills training, and tertiary interventions such as counselling.

In this current COVID-19 pandemic, the elderly (60 years and over) are more vulnerable populations to be infected and become victims. In a disaster cycle, the various parts are usually divided into three stages, consisting of the pre-impact stage, the trans-impact stage, and the post-impact stage. It is necessary to explain how to handle the COVID-19 disaster for the elderly at each step (explain the meaning of pre-case, case (pre-hospital and hospital), and post-case phases, respectively). This paper presents the handling of COVID-19 for elderly in pre-case, case, and post-case phases in six Asia-Pacific countries (Indonesia, Thailand, Singapore, Malaysia, Vietnam, and Japan). The data and information come from COVID-19 official websites of each country, including information from World Health Organization (WHO), United States Centers for Disease Control and Prevention (CDC), mass media, and professional associations. The handling of COVID-19 in the pre-case phase has been done correctly for the elderly, especially in Indonesia, Japan, Thailand, and Singapore. In the case phase (pre-hospital and hospital), only Indonesia, Japan, and Thailand have followed special handling protocols for the elderly, particularly for those who have comorbidities and respiratory diseases. For the post-case phase, all countries have the same treatment protocol for all age groups, with none specific for the elderly.
RESUMEN
Workplace bullying is a pervasive phenomenon among junior doctors that may negatively impact their training and abilities to deliver quality healthcare, yet evidence on the factors of bullying among them remains lacking. This study examined the role of organisational climate, culture, leadership, support, and justice in junior doctors' exposure to workplace bullying on the basis of the work environment hypothesis, which suggests that workplace psychosocial factors are the main antecedents of bullying at work. Multilevel analysis of a universal sample (n = 1074) of junior doctors working in the central zone of Malaysia, using mixed effects logistic regression, was conducted. Analysis indicates that junior doctors working in departments with neutral and positive organisational climate, moderate and high degree of clan culture, moderate and high degree of adhocracy culture, moderate degree of hierarchy culture, moderate degree of production and achievement-oriented leadership style, moderate and high degree of organisational support, moderate degree of procedural justice, moderate and high degree of interactional justice, and high degree of distributive justice have lower odds of bullying compared with their counterparts. The results present evidence that all aspects of the organisation influence junior doctors' exposure to bullying and should be considered when developing antibullying initiatives targeted at them.

BACKGROUND: Radioprotective garments protect medical radiation workers from exposure to radiation at workplace. However, previous studies have found poor adherence to the use of radioprotective garments. OBJECTIVES: We explored the perceptions and practices related to the use of radioprotective garments among medical radiation workers in public hospitals, and sought to understand the reasons for non-adherence. DESIGN AND SETTING: A qualitative approach was applied by conducting face-to-face in-depth interviews with 18 medical radiation workers from three university hospitals using a semi-structured interview guide. RESULTS: Five themes emerged with respect to perceptions on the use of radioprotective garments: (i) the dilemmas in practising radiation protection, (ii) indication of workers' credibility, (iii) physical appearance of radioprotective garments, (iv) practicality of radioprotective garment use, and (v) impact on workflow. Actual lack of radioprotective garment use was attributed to inadequate number of thyroid shield and other garments, radioprotective garments' unsightly appearance including being dirty and defective, impracticality of using radioprotective garments for some nuclear medicine procedures, disruption of workflow because of workers' limited movements, attitudes of workers, and organisational influences. CONCLUSION: Medical radiation workers demonstrated a definitive practice of using radioprotective aprons, but often neglected to use thyroid shields and other garments. Availability and hygiene are reported as the core issues, while unclear guidelines on practical use of radioprotective garments appear to lead to confusion among medical radiation workers. To the best of our knowledge, this is the first qualitative study of its kind from a middle-income Asian setting.
RESUMEN
Consumption of curry containing poppy seeds has raised an issue concerning the opiate content in the urine that might exceed the cut-off value (300ng/mL). The main objective of this study was to examine the morphine and codeine contents in the urine of the consumers after partaking poppy seed-enriched curry in. The volunteers were asked to partake: (a) a single meal and their urines were collected within 24h, or (b) Two meals a day for three consecutive days and their urines were collected within 72h. Two different dosages were also tested in this study: (a) low dosage: 1g/100ml curry (containing 138µg of morphine and 66µg of codeine) and (b) high dosage: 5g/100ml curry (containing 690µg of morphine and 330µg of codeine). The subjects were randomised into the groups using the method of stratified randomization with age and gender groups as covariates. A total of 6 subjects was allocated for each group and placebos were used as control. Results showed that all subjects who consumed low dosage of poppy seeds either in single meal or multiple meals experiment were found negative. However, 1 out of 6high dosage subjects was confirmed positive at a period of 3-6h after the consumption of curry in the single meal study. This outlier maybe due to the lack of water consumption after consuming the curry, thus the low volume of urine was collected and the opiate was concentrated in the urine. On the other hand, 5 out of 6high dosage subjects in the multiple meals experiment were found positive. Majority of these subjects were found positive on the second and third day of the experiment after the second curry meal was consumed. The outlier (negative) in this group might be due to the high consumption of water throughout the experiment and the subject's urine volumes and frequency of urine collection were much higher compared to other subjects. From the result of this study, it can be concluded that partaking high dosages of poppy seed in curry could give a positive response (>300ng/ml+uncertainty of measurement) in the urine, and the water consumption after partaking curry has significant influence for the opiate contents in the urine.

There is increasing popularity among researchers, scholars, and policymakers concerning the efficacy of prayer as a coping strategy for job stress. This study examines the moderating effects of prayer and age on the relationship between job stress and nurses' well-being in UMMC. Three hundred (300) Muslim nursing staff working at the University of Malaya Medical Centre were sampled. Data were collected via questionnaires. The findings of this study show that the effect of job stress on well-being is significant for nurses and that prayer of nurses contributed to alleviating job stress and enhancing well-being. This study is limited to nurses in one public hospital in a developing country. Thus, it would be more interesting if the study could be extended to other public and private institutions in a Muslim country, and a comparison could be done between other religions as well.

Economic losses due to health-related implications of air pollution were huge and incurred significant burdens towards healthcare providers. The objective of this study is to systematically review published literature on the financial implications of air pollution on health in Asia. Four databases: PubMed, Scopus, NHS Economic Evaluation Database (NHS EED), and Web of Science (WoS) were used to identify all the relevant articles. It was limited to all articles that had been published in the respected databases from January 2007 until March 2017. Twenty-four articles were included in this review. Five of the 24 studies (20.8%) reported financial implications of air pollution-related disease through value of statistical life (VOSL) which ranged from USD180 million to USD2.2 billion, six (25%) studies used cost of illness (COI) to evaluate air pollution-related morbidity and found that the cost ranged from USD5.4 million to USD9.1 billion. Another six studies (25%) used a combination of VOSL and COI for both mortality and morbidity valuation and found that the financial implications ranging from USD253 million to USD2.9 billion. Thirteen (54.2%) studies reported healthcare cost associated with both hospital admission and outpatient visit, five (20.1%) on hospital admission only, and one (4.2%) on outpatient visit only. Economic impacts of air pollution can be huge with significant deterioration of health among the Asians.

Quality of life is associated with several factors, including personal living styles and working conditions. This article aims to investigate the factors associated with quality of life among small and medium enterprises (SME) workers in 4 countries of the Association of Southeast Asian Nations (ASEAN), namely Malaysia, Indonesia, Thailand, and Vietnam. A total of 2014 workers from food and textile industries were asked to answer a questionnaire about their sociodemographic characteristics, working environment and conditions, and quality of life. Results from showed that lifestyle (ie, alcohol intake and exercising), working characteristics (ie, shift work, working hours, and working days) and workplace conditions were associated with SME workers' quality of life (ie, physical, psychological, social, and environmental domain). Among the 16 types of workplace conditions, "sitting on the chair" and "slippery floor" most affect their quality of life . It is important for these variables to be taken into account in promoting workers' well-being and quality of life.

Work ability is related to many factors that might influence one's capacity to work. This study aimed to examine the work ability and its related factors among small and medium enterprises (SME) workers in 4 Association of Southeast Asian Nations (ASEAN) countries. The participants in this study included 2098 workers from food and textile industries in Indonesia, Malaysia, Thailand, and Vietnam. A cross-sectional survey of anonymous self-administrated questionnaire was designed to collect information on sociodemographic factors, work environment and ergonomic condition, musculoskeletal disorders, and work ability. Bivariate correlation coefficient and multiple linear regression analyses were used to predict the work ability. Results of this study confirm that work ability in 4 ASEAN countries was similar to that in European countries, and that the sociodemographic factors, work environment and ergonomic condition, and musculoskeletal disorder (MSD) were associated with work ability. These factors are important for considering occupational health and safety policy to promote work ability in food, textile, and other SME workers.

This study aimed to explore the clinical characteristics of hand arm vibration syndrome (HAVS) in a group of tree fellers in a tropical environment. We examined all tree fellers and selected control subjects in a logging camp of central Sarawak for vibration exposure and presence of HAVS symptoms utilizing vibrotactile perception threshold test (VPT) and cold water provocation test (CWP). None of the subjects reported white finger. The tree fellers reported significantly higher prevalence of finger coldness as compared to the control subjects (OR=10.32, 95%CI=1.21-87.94). A lower finger skin temperature, longer fingernail capillary return time and higher VPT were observed among the tree fellers as compared to the control subjects in all fingers (effect size >0.5). The VPT following CWP of the tree fellers was significantly higher (repeated measures ANOVA p=0.002, partial η(2)=0.196) than the control subject. The A (8) level was associated with finger tingling, numbness and dullness (effect size=0.983) and finger coldness (effect size=0.524) among the tree fellers. Finger coldness and finger tingling, numbness and dullness are important symptoms for HAVS in tropical environment that may indicate vascular and neurological damage due to hand-transmitted vibration exposure.

The main objective was to find association between basal cortisol and neighborhood-level stress. Systematic searches, including electronic and hand searches, were conducted. The most recent date of the search was July 26, 2013. Primary observational studies included if they considered stress related outcomes in the neighborhood context. Using the EndNote X7 advanced search option; the authors examined the abstracts and titles of the 18,092 articles to exclude obviously irrelevant studies, gray literature, discussion papers, reviews and, studies with no complete data. Two authors independently extracted data from the original reports into pre-designed data extraction forms based on the Data Extraction Template of the Cochrane Consumer and Communication Review Group (CCCRG). Ten studies with a total of 2,134 participants were synthesized and analyzed. Two studies out of ten received expanded meta-analysis. The overall effect size (95% CI) for cortisol level for residents in neighborhoods with lower stress compared to inhabitants from higher was 0.12 (0.01, 0.23). This review is demonstrating a link between psychosocial or physical stress and cortisol obtained from saliva. However, living in high disorder neighborhoods results in higher level of cortisol. This represents a biological indicator of psychosocial/physical stress exposure (i.e., neighborhood disorder) that reflects variances in stress exposure levels.
