ntal data for this article is available online at.Objectives. The main purpose of this study is to reveal the moderating effect of psychological well-being on the effect of workplace safety climate on job stress. Methods. The cross-sectional study design included the survey method. A total of 291 healthcare professionals returned the survey forms, among which 75.9% were women, and the mean age of the sample was 32.83 ± 6.03 years. Most of the participants (66.6%) had a bachelor's degree or higher. We analyzed the data using a structural equation modeling framework to test both direct and mediating effects. Hayes' Model 4 was used to identify the mediating role of psychological well-being on the effect of workplace safety climate on job stress. Results. According to the analysis results, the created model is significant, and psychological well-being plays a mediating role on the effect of workplace safety climate on job stress, reinforcing the negative effect of workplace safety climate on job stress. Conclusion. First, the safety environment perceived by employees reduces their stress. Second, psychological well-being plays a mediating role in relation to the effect of safety climate on job stress. This role contributes to the reduction of stress through the improvement of the safety climate.Objectives. Computer use, as in typing, might contribute to trapezius myalgia (TM) development by increasing upper trapezius (UT) muscle fatigue. The purpose of this study is to investigate whether 10 min of performing a typing task by a population at risk would show significant changes in surface electromyography (sEMG) and pressure pain threshold (PPT) measurements. Supported and unsupported forearms postures are compared. Methods. Sixteen asymptomatic volunteers with minimum daily use of a computer of 5 h were randomized into two groups fully supported forearms (n = 8) and unsupported forearms (n = 8). [https://www.selleckchem.com/products/dl-ap5-2-apv.html 2-APV] The protocol consisted of 10 min of a typing task, and the workstation was set according to the usual participant profile. sEMG and PPT readings were collected from both UT muscles. Results. PPT and sEMG readings were not significantly different among the two groups. Supported forearms had less reduction of PPT and a smaller increase in electrical activity. Conclusions. Ten minutes of typing seems insufficient to observe any significant changes that could lead to TM development.Studies on social factors that could influence the mental health-suicidal ideation link remain scarce, especially in non-Western contexts. This study examined the relationship between mental health symptoms (i.e., depression, anxiety, and stress) and suicidal ideation and whether one's perceived social rank moderates such a relationship. Data from 631 students from two universities in the Philippines collected between October to December 2018 was analyzed. Bivariate correlations show that greater symptoms of depression, anxiety, and stress are associated with increased suicidal ideation. Hierarchical linear regression models supported the direct relationship between mental health symptoms and suicidal ideation and demonstrated that perceived social rank significantly moderated such a relationship. Johnson-Neyman plots and simple slopes analyses further illustrate how mental health symptoms and perceived social rank interact to impact suicidal ideation. The results show that as one's perceived social rank lowers, the strength of the positive association between depression, anxiety, and stress symptoms to suicidal ideation strengthens. The results held while controlling for age, gender, college year level, and family income. The findings are discussed using the social rank theory and the Integrated Motivational-Volitional (IMV) model of suicide to view suicidal ideation from both an individual and a social perspective. We expound on the role of low perceived social rank on suicidal ideation among young adults.HIGHLIGHTSHigher depression, anxiety, and stress symptoms are associated with higher suicidal ideation.Perceived social rank moderates the link between mental health symptoms and suicidal ideation.One's perception of being inferior to others can exacerbate suicidal ideation.Objectives. This study aimed to assess the prevalence of self-reported musculoskeletal symptoms among nurses in Bahrain and determine the factors that contribute to the occurrence of these symptoms. Methods. A cross-sectional study was conducted using data from a convenience sample of 550 nurses working in three hospitals in the Kingdom of Bahrain. The prevalence of self-reported musculoskeletal symptoms in the last 12 months was assessed using the self-administered Nordic musculoskeletal questionnaire (NMQ). Results. A total of 550 nurses participated in the study. Most were females (n = 488, 89.1%) between 31 and 40 years of age (n = 239, 43.8%). The overall self-reported prevalence of musculoskeletal complaints of all joints in the past 12 months was 88.1%. The highest prevalence was in the lower back (72.3%), followed by the shoulder (52.8%) and the neck (49%). The lowest prevalence was the elbow (12.1%). The prevalence of lower back symptoms was significantly associated with age (p  less then  0.001), coexisting medical conditions (p  less then  0.001), area of practice (p  less then  0.001), number of tasks (p  less then  0.001) and types of shifts (p  less then  0.001). Conclusion. The findings indicate a high prevalence of symptoms among nurses. There is a need to implement strategies in healthcare facilities to improve working environment conditions and reduce the prevalence rate.Human error is an important factor leading to nuclear power plant (NPP) accidents. Human reliability analysis (HRA) is considered an effective method to reduce human error. Therefore, this article proposes a method to quantify human reliability based on the standardized plant analysis risk-human reliability analysis (SPAR-H) method. Firstly, the method used the performance shaping factors of SPAR-H to build a human reliability model. Secondly, the triangular fuzzy number was used to quantify the qualitative information of root nodes, and the fuzzy IF-THEN rule was used to determine the prior probability distribution of intermediate nodes. Finally, Bayesian reasoning was used to quantify human reliability based on the human reliability model. The result of the developed method is consistent with the result of cognitive reliability and error analysis methods (CREAM). The developed method can be used as a tool to quantify human reliability in the NPP system.Previous biomechanics studies suggest that higher cognitive mental workload when performing office computer tasks may increase the risk of MSDs among office workers. Cognitive workload can be interpreted in terms of task factors (e.g. task complexity and time pressure) and mental workload factors which include mental demand and mental effort. A laboratory study was conducted to further explore how the task and mental workload factors affected computer users' biomechanical responses, specifically the muscle activation levels and sitting postures. Data were collected as 20 participants worked on computer tasks which varied in their levels of task complexity and time pressure. Visual analog scales were used for assessing mental workload factors. Results indicated that the level of mental effort reported, as opposed to the level of task complexity, was associated with changes in participants' biomechanical responses, but primarily occurred when the chair's backrest was not used. Practitioner summary A study was conducted to investigate the association between computer users' cognitive workload and biomechanical responses when performing computer task. While task complexity was not directly associated with the changes in participants' biomechanical responses, higher reported mental effort was associated with increased biomechanical responses, but only when the participants did not use the backrest on the chair.Physically and mentally healthy seafarers with professional knowledge and skills are needed for maritime transportation to be safe and sustainable. Mental problems experienced by seafarers can lead to negative consequences, such as bullying, substance dependency, assault, murder and suicide. Accordingly, this study examined the effects of differences between the socio-demographic characteristics of Turkish seafarers on their depression, which is an important criterion for determining mental disorders. Data collected from 403 participants through quantitative research methods were analyzed using SPSS version 25.0 and AMOS version 23.0. Although periodic physical and mental health checks are performed on seafarers, it was found from the analysis results that 33.2% of Turkish seafarers experience mental issues. Moreover, the study determined that the socio-demographic characteristics of seafarers made some differences in their depression levels.<br />The COVID-19 pandemic has claimed the lives of more than 800,000 people in the United States (US) and has been estimated to carry a societal cost of $16 trillion over the next decade. The availability of COVID-19 vaccines has had a profound effect on the trajectory of the pandemic, with wide-ranging benefits. We aimed to estimate the total societal economic value generated in the US from COVID-19 vaccines.<br />We developed a population-based economic model informed by existing data and literature to estimate the total societal value generated from COVID-19 vaccines by avoiding COVID-19 infections as well as resuming social and economic activity more quickly. To do this, we separately estimated the value generated from life years saved, healthcare costs avoided, quality of life gained, and US gross domestic product (GDP) gained under a range of plausible assumptions.<br />Findings from our base case analysis suggest that from their launch in December 2020, COVID-19 vaccines were projected to generate $5.0 trillion in societal economic value for the US from avoided COVID-19 infections and resuming unrestricted social and economic activity more quickly. Our scenario analyses suggest that the value could range between $1.8 and $9.9 trillion. Our model indicates that the most substantial sources of value are derived from reduction in prevalence of depression ($1.9 trillion), gains to US GDP ($1.4 trillion), and lives saved from fewer COVID-19 infections ($1.0 trillion).<br />Constructed as a projection from December 2020, our model does not account for the Delta or future variants, nor does it account for improvements in COVID-19 treatment.<br />The magnitude of economic benefit from vaccination highlights the need for coordinated policy decisions to support continued widespread vaccine uptake in the US.<br />The magnitude of economic benefit from vaccination highlights the need for coordinated policy decisions to support continued widespread vaccine uptake in the US.<br />Pancreatic Ductal Adenocarcinoma (PDAC) is an aggressive disease with poor outcomes. One of the reasons for the dismal prognosis resides in its impressive ability to alter the nutritional status of patients who develop malnutrition, cachexia, anorexia, and sarcopenia in most cases. The ideal way to measure such changes in PDAC patients, in order to readily identify them and avoid complications or discontinuations of treatment is a relatively unexplored area. In addition, most PDAC patients experience pancreatic exocrine insufficiency (PEI) that contributes to the complex puzzle of malnutrition and that can be treated with Pancreatic Enzyme Replacement Therapy (PERT).<br />We review current knowledge on the impact of nutritional status on both surgical and medical treatments for PDAC, reporting available data on the causes of malnutrition, characteristics, and advantages of different tools to investigate nutritional status and possible strategies to improve patient outcomes.<br />All PDAC patients should receive a careful nutritional assessment at diagnosis, and this should be repeated alongside their treatment path.
