Background There is strong observational evidence that respirators are highly effective in protecting the users from being infected with Middle East respiratory syndrome and severe acute respiratory syndrome coronavirus (SARS-CoV), but the evidence for SARS-CoV-2 during daily work is limited. This study utilized a subset of healthcare workers' temporary use of a new brand respirator with frequent defects when caring for coronavirus disease 2019 (COVID-19) patients to assess the protective effect of regular respirators against SARS-CoV-2 infection. Methods We retrospectively followed 463 participants wearing a regular respirator and 168 wearing the new brand respirator day-by-day when caring for COVID-19 patients until testing polymerase chain reaction positive for SARS-CoV-2 between 27th December 2020 and 14th January 2021. Results We observed seven and eight incident SARS-CoV-2-infected cases. This corresponded with daily infection rates of 0.2 and 0.5%, an incidence rate ratio of 0.4 [95% confidence interval (CI) 0.1; 1.0], and an incidence rate difference of 0.3% (95% CI −0.1; 0.8) when comparing a regular with the new brand respirator. Discussion We regard the new brand respirator a sham intervention, and this study thus provides further evidence for the protective effect of respirators when exposed to SARS-CoV-2 virus.

Work-related threats and violence is a major occupational hazard and the consequences for victims may be a range of physical and psychological symptoms. The purpose of this study was to examine the associations between exposure to work-related violence and threats and subsequent risk for depression and to examine whether the associations were modified by social support, organizational justice and safety perceptions. Questionnaire data was collected in 2010, 2011 and in 2015. A total of 5,342 employees from special schools, psychiatric wards, eldercare and the Prison and Probation Services (PPS) participated in the first round in 2010. The analysis was performed by multivariate logistic regression. Staff exposed for work-related threats and violence had an increased risk for depression compared to non-exposed staff. The risk was highest for staff working in PPS. Compared to low levels, there were a tendency for high levels of social support, organizational justice and safety perception to attenuate the associations between work-related threats and violence and depression. However, none of the differences were statistically significant. Many employees working in human service sectors are exposed to work-related threats and violence which increases the risk for depression. The risk for depression following work-related threats and violence may be modified by social support, organizational justice and the perception of safety workplace. It is recommended that workplaces adopt an integrated organizational approach including both prevention of work-related threats and violence and intervention to modify the health consequences of work-related threats and violence.

Purpose: Fatigue following breast cancer is a well-known problem, with both high and persistent prevalence. Previous studies suffer from lack of repeated measurements, late recruitment and short periods of follow-up. The course of fatigue from diagnosis and treatment to the long-time outcome status is unknown as well as differences in the level of fatigue between treatment regimens. The purpose of this study was to describe the long-time course of fatigue from the time of clinical suspicion of breast cancer, its dependence of patient characteristics and treatment regimens and the comparison with the course of fatigue among women with the same suspicion, but not diagnosed with breast cancer. Methods: Three hundred thirty-two women referred to acute or subacute mammography was followed with questionnaires from before the mammography and up to 1500 days. Fatigue was measured by the Multidimensional Fatigue Inventory (MFI-20). The women reported their initial level of fatigue before the mammography and thus without knowledge of whether they had cancer or not. Both women with and without cancer were followed. Women with cancer were identified in the clinical database established by Danish Breast Cancer Cooperative Group (DBCG) to collect information on treatment regimen. Results: Compared to fatigue scores before diagnosis, women with breast cancer reported a large increase of fatigue, especially in the first 6 months, followed by a slow decrease over time. Despite the long follow-up period, the women with breast cancer did not return to their level of fatigue at time of the mammography. Women without breast cancer, experienced a rapid decrease of fatigue after disproval of diagnosis followed by a steadier period. Conclusions: Fatigue is a persistent problem in women diagnosed with breast cancer, even several years following diagnosis and treatment. The women with breast cancer were most affected by fatigue in the first 6 months after diagnosis. [ABSTRACT FROM AUTHOR]

BACKGROUND: Work-related violence and threats are frequent in human service sectors. Although previous studies have identified several psycho-social work environmental risk factors for work-related violence and threats, the research domain still remains mainly descriptive and non-theoretical in nature. OBJECTIVE: Using the Job-Demands-Control model we analysed the relationship between the psycho-social work environment and work-related threats and violence. METHOD: Using a two-wave (2011 and 2015) longitudinal study of 2678 participants, we analysed the main and interactive effects of quantitative demands and job control on exposure to work-related violence and threats. RESULTS: High work demands and low job-control were associated with elevated risk of work-related threats in 2011 and in 2015. The associations of work demands and job control and work-related violence were mixed. There were not statistically significant interaction effects between high demands and low job control on neither work-related violence nor threats. CONCLUSION: In sectors where work-related threats and violence are likely to occur, risk prevention may also require improving the work conditions for employees, more specifically by reducing work-demands and increasing job control for instance by differentiating between important and less important work demands and by implementing self-autonomous work-teams may be a way to increase job control.

BACKGROUND: The frequency of being exposed to work-related violence and threats is high in employees working in the human service sector. The question is whether certain employees are particularly exposed to violence and threats than others. OBJECTIVE: This study examined whether particular employees were especially exposed to work-related violence and threats due to personal characteristics, coping styles, attitudes or participating in violence prevention training. We also examined the role played by supervisors. METHODS: Questionnaire data were collected in 2010 and 2011. In all, 3584 employees from special schools, psychiatric wards, eldercare and the Prison and Probation Service participated. We used multivariate logistic regression analyses. RESULTS: We found persons high on the extroversion and introversion scales were associated with statistical significant increased risk for work-related threats. Furthermore, accepting attitudes concerning work-related violence were also statistical significant associated with increased the risk for both work-related threats and violence. Associations between coping styles and work-related threats and violence were very small and statistically non-significant and we found no effect of violence prevention training. The risk for work-related threats for persons high on the extroversion scale was decreased if supervisor violence prevention behaviour was high. Furthermore, if supervisor prevention behaviour was high, prevention training decreased the risk for work-related violence. However, these associations weren't statistically significant. CONCLUSION: The results stress that effective prevention requires involvement of both employees and supervisors. [ABSTRACT FROM AUTHOR]

Purpose A total of 243 Danish female sewing machine operators lost their jobs in 1996 because of outsourcing. The aim was to investigate the employment status during follow-up from 1996 to 2008, and to estimate to what extent former neck–shoulder pain had an impact on later work participation. Methods Assessment of neck–shoulder pain was based on questionnaires completed in 1994. The Danish Register-Based Evaluation of Marginalization (DREAM) register was used to describe employment status during the follow-up period. Register data were explored by sequence analyses and graphics, and the association between neck–shoulder pain and work participation was analyzed by logistic regression analysis. Results In all, 987 working years were lost during follow-up, and a sequence index plot revealed interrupted and heterogeneous courses of incomes. The odds ratio between neck and shoulder pain and a work participation score less than 75% was 1.49 (95% CI 0.84–2.67). Conclusions After outsourcing of the textile industry, the former sewing machine operators had decreased work participation and frequent transitions between different income types. Previous neck–shoulder pain tended to be associated with poor work participation. The results suggest that increased attention should be to given to dismissed workers from other industries that become outsourced, especially unskilled workers with similar work-related health limitations. Additionally, we concluded that time-to-event measures in research involving employment status are insufficient because of the many transitions that take place in working life.

BACKGROUND: Threats and violence at work are major concerns for employees in many human service sectors. The prevention of work-related violence is a major challenge for employees and management. OBJECTIVE: The purpose of this study was to identify prospective associations between psycho-social work environment and work-related threats and violence in four high risk human service sectors. METHODS: Questionnaire data was collected from 3011 employees working at psychiatric wards, in the elder sector, in the Prison and Probation Service and at Special Schools. Associations between psycho-socialwork environment andwork-related violence and threats were then studied using a one-year follow-up design and multilevel logistic regression analyses. RESULTS: The analyses showed that quantitative demands, high emotional demands, low level of influence over own work-situation, low predictability, low rewards at work, low role clarity, many role conflicts, many work-family conflicts and low organizational justice had statistically significant associations with high levels of work-related threats. Furthermore, high emotional demands, low predictability, low role clarity, many role conflicts, many work-family conflicts, low supervisor quality and low support from nearest supervisor had statistically significant associations with high levels of work-related violence. Finally, across the four sectors both similar and different associations between psycho-social work environment and work-related violence and threats were found. CONCLUSION: The results of the study underline the importance of including the psycho-social work environment as a supplement to existing violence prevention methods and interventions aimed at reducing work-related violence and threats.

Aim Menarcheal age is a predictor of several complications related to pregnancy and diseases later in life. We aimed to study if menarcheal age is a risk factor for pregnancy-related pelvic pain. Material and Methods A nested case-control study was conducted within the Danish National Birth Cohort, a cohort of pregnant women, recruited during 1996-2002, and their children. In the second trimester of pregnancy the women provided information about age at menarche and potential confounders. Selection of cases ( n = 2227) was based on self-reported pelvic pain during pregnancy from an interview done 6 months post-partum. The controls ( n = 2588) were randomly selected among women who did not report pelvic pain. We used logistic regression analysis to calculate odds ratios ( OR) for pregnancy-related pelvic pain according to age at menarche. Results In the cohort, 18.5% of all pregnant women reported pregnancy-related pelvic pain. Compared to women who were 12-14 years old at menarche, the adjusted OR for overall pelvic pain were 1.4 (95% confidence interval [ CI] 1.1-1.7) in women 11 years or younger and 0.8 (95% CI 0.6-0.9) in women 15 years or older. The corresponding adjusted OR for severe pelvic pain were 1.6 (95% CI 1.3-2.0) and 0.7 (95% CI 0.6-0.9). When age was analyzed as a continuous variable, the odds for overall and severe pelvic pain decreased with 14% and 16%, respectively, for each increasing year. Conclusions The risk of pregnancy-related pelvic pain decreased with increasing menarcheal age in an 'exposure-response' pattern. A low menarcheal age is a risk indicator and may be a risk factor for pregnancy-related pelvic pain. [ABSTRACT FROM AUTHOR]
