RESUMEN
Introduction@#The construction workers are performing manual tasks in harsh conditions. Various environmental risk factors could have significant influence on work fatigue. @*Methods@#This review article discussed the environmental causal factors which involved in work fatigue development in the occupational health perspective, with the aim in enhancing the body of knowledge specifically in the construction industry so that mitigation measures and interventions can be formulated and implemented for fatigue prevention and productivity enhancement. @*Results@#Data derived from a total of 11 relevant articles identified climatic heat, vibration and elevation change as the major risk factors that associated with work fatigue. The mechanism of the environmental factors’ influences on muscle, mental and visual fatigue were understood, pointedly the underlying physiological alteration. Additionally, appropriate preventive measures in accordance to the OSHA guides including work-break cycles, work management, cool-down arrangements with drinking water were discussed. The limitation of existing OSH requirements on work limits at heat exposure was recognized, including the lack of consideration on personal characteristics therefore might inaccurately estimate the personal heat tolerance time. @*Conclusions@#The proper understanding of the environmental stressors and its impact on workers production and safety performance may help construction organisations and regulatory body to develop strategies for workers protection and fatigue-related accidents prevention.
RESUMEN
@#A 28-year-old female laboratory technologist who was exposed to highly concentrated inorganic arsenic for 7 years, 25 hours a week, presented with left breast cancer. When most epidemiologic evidence reported by the International Agency for Research on Cancer (IARC) supported the relationship between arsenic exposure and cancers of lung, skin and bladder; literature had documented increased risk of breast cancer in specific populational subgroups due to the estrogen-like activity of arsenic. The existing available control measures are restricted to the administrative control such as training and job rotation, hence making the causal assessment of occupational cancer is challenging due to the lack of relevant data on the worker’s biological monitoring and environmental exposure monitoring data, together with the insufficient genetic composition information like Breast Cancer Genes1 (BRCA1). Moreover, the poor work practice and hygiene had made the exposure through dermal contact and digestion possible. The interpretation of work causal relationship while distinct occupational cancer from those of non-occupational must consider individual susceptibility as lowlevel short-period exposure might increase the risk for certain worker. Therefore, a systematically collected medical surveillance data along with industry hygiene data is highly recommended in order to assist in the refinement of human dose-response relationship of specific work carcinogen
RESUMEN
Background and aims@#Forest bathing or Shinrin-Yoku is a practice of being mindful of nature and it offers multiple health benefits in both physiological and psychological factors. This study aimed to determine the knowledge and attitude of Universiti Kebangsaan Malaysia (UKM) medical students towards forest bathing and its relationship with the sociodemographic factors. @*Materials and methods@#A total of 165 UKM medical students were recruited using proportionate random sampling. The subjects were then categorized based on the academic year (Year 1 - Year 5). Exclusion criteria includes those who deferred their academic year and/or who were hospitalized. A questionnaire was given via a google form consisting of sociodemographic data details and 15 questions for each knowledge and attitude on forest bathing. @*Results@#The prevalence of good knowledge and good attitude of UKM medical students towards forest bathing were 64.2% (n=106) and 50.9% (n=84) respectively. Female medical students had a good knowledge (n=63, 73.3%) and good attitude (n=52, 60.5%) compared to male medical students' knowledge (n=43, 54.4%) and attitude (n=32, 10.5%) leading to a p-value of 0.012 and p-value of 0.010. Otherwise, other sociodemographic factors including race, level of medical year and level of lifestyle did not affect participants' knowledge and attitude on forest bathing. @*Conclusion@#Majority of UKM medical students have a higher prevalence of good knowledge compared to good attitude on forest bathing. Therefore, intervention is recommended especially towards male medical students as forest bathing has enough evidence as preventive medicine.
RESUMEN
@#Dual competing responsibilities between work and family are the challenges faced by most of the healthcare staff. Ineffective handling of these responsibilities may contribute to absenteeism which further disrupt the quality of work and reduce customer satisfaction. The aims of this study were to determine the prevalence of job absenteeism and to identify the association between family responsibilities and job absenteeism among nurses in teaching hospital. This was a cross sectional study targeted to nurses working in medical and surgical field based in a hospital. Questionnaires were distributed using stratified random sampling. Those with working services of less than one year were excluded. The mean age was 35.9 (SD=6.44) years old. Majority were female (94.0%) and Malay (96.0%). The one-year prevalence of absenteeism was 78.0% and majority were due to emergency leaves. Taking care of elderly and no help obtained for taking care of child showed significant associations with job absenteeism which both yielded four times higher odds for being absent. Employees with additional family responsibilities should receive support by the organisation to prevent further job absenteeism among nurses.
RESUMEN
@#Healthcare workers typically work in shift to ensure smooth operation of healthcare industries around the clock. However, working in shift put them at risk of developing occupational fatigue and sleepiness during and after work, with multiple adverse effects to themselves and patients under their care. This review aims to identify available evidence-based intervention for fatigue and sleepiness among healthcare workers working in shift. We searched PubMed, Scopus and CENTRAL database from January 2013 to December 2017. Selection criteria included randomised controlled trials (RCTs) that investigated the effect of any interventions on fatigue and/or sleepiness among shift workers. Two authors independently screened titles and abstracts for relevant studies, extracted data, and assessed risk of bias. We included 8 relevant trials with 7 review-relevant participants. Given the methodological diversity of the included studies in terms of interventions and assessment tools, it is not possible to determine the effectiveness of these interventions to reduce occupational fatigue or sleepiness among healthcare workers working in shift. More good quality RCTs with comparable assessment tools is needed.
RESUMEN
Air pollution has been widely known to have an influence on health of the general population. Air pollution can result from natural causes, human activities and transboundary air pollution. Weather and climate play crucial role in determining the pattern of air quality. In recent years, air pollution and recurrent episodes of haze has become a major concern in Malaysia. Surveillance data on concentrations of main air pollutants such as carbon dioxide, (CO2), Nitrogen Dioxide (NO2), Ozone (O3), sulphur dioxide (SO2) and particulate matter (PM10) were found to be higher during the haze days and this may have an impact on health of the community as reflected by an increase in hospital admissions particularly the respiratory and cardiovascular diseases.
