W e deplore the tone of the Egilman et al letter questioning our (Fordyce et al) scientific integrity. We also take strong exception to what appear to be intentional misrepresentations of our paper. For example, Egilman et al state, ‘‘Fordyce’s et al study report [sic] 2 mesothelioma cases in a cohort of 427 workers.’’ We went to great lengths to find every case of mesothelioma in this cohort of workers. We found a single case over the entire period of observation, from 1930 through 2012. Egilman et al count a second case based on an article by Lamm and Starr, which was not published in a peer-reviewed journal and provided no information on the single case of mesothelioma that they claimed to have found. We were unable to verify this claim after an exhaustive search of the death certificates of workers in the expanded cohort of Vermont talc workers, as described in our paper. It is simply incorrect to say that we reported two cases of mesothelioma in this cohort, a false claim that Egilman et al repeat at least three times in their letter. All of the calculations in the Egilman et al letter based on two mesothelioma deaths are, therefore, incorrect. It is also incorrect to allege that we stated that the workers in the cohort had no occupational exposure to asbestos. We did not state this, and it is not true: the

OBJECTIVE To evaluate the relationship between utilization of institution-affiliated childcare andemployee stress among parents working at a large, academic medical center. METHODS Cross-sectional analysis of the relationship between institution-affiliated childcare and employee stress. Survey questions asked about personal stress related to job, relationship with spouse, parental responsibilities, childcare, finances, and personal health. RESULTS 558 (68%) respondents were predominantly female (76.9%). Fifty-four percent had non-institution-affiliated childcare and 45% had institution-affiliated childcare. Use of institution-affiliated childcare was associated with less overall stress (-4.86 [95% confidence interval -8.01, -1.72], p = 0.003), and less stress related to finances, childcare, and personal health. Differences between groups related to job, relationship with spouse, or parental responsibilities were not statistically significant. CONCLUSIONS This study demonstrated an association between institution-affiliated childcare andlower stress, highlighting the centrality of employer-affiliated childcare to employees' stress.

OBJECTIVES The purpose of this study was to determine the inflammatory response to a 12-hour wildfire suppression shift, in firefighters attending the "Black Saturday" natural disaster. METHODS Thirty-eight male volunteer firefighters provided venous blood samples before and after a 12-hour firefighting shift. Pre- to post-shift changes in pro-inflammatory (Interleukin [IL]-1β, IL-2, IL-6, IL-8, IL-12P70, granulocyte macrophage-colony stimulating factor [GM-CSF], tumor necrosis factor-alpha [TNF-α], interferon-gamma [IFNγ]), and anti-inflammatory (IL-4, IL-5, IL-7, IL-10, IL-13) cytokines were measured with paired sample t tests, or Wilcoxon t tests for non-parametric data. RESULTS Interleukin (IL)-6 (P = 0.003) and IL-8 (P = 0.017) were significantly increased following 12-hours of wildfire suppression. There was also a significant decrease in IL-10 (P = 0.021). CONCLUSIONS The observed acute inflammatory response may have resulted from multiple stressors including physical exertion, thermal strain, or smoke inhalation experienced during the shift, and may be a necessary response for the body to adapt to stressor exposure.

W ith dairy and crop farming being the largest sectors, agriculture and horticulture provide employment approximately for 100,000 people in Finland. Agriculture workers have a high risk for exposure to respiratory hazards. Because only a small portion of the overall population is employed in agriculture, respiratory disease in farmers is not a major public health issue. Despite this, the health and well-being of farmers as well as their health risk reduction in their working conditions needs to be examined, especially because a farming environment has been thought to prevent the development of allergies. Respiratory diseases and symptoms are well-recognized occupational problems among farmers. Agricultural workers in all sectors of farming are exposed to various types of airborne toxins and allergens in their work, including organic dust, pesticides, and microbes. Several different types of gases (eg, ammonia, methane, and carbon dioxide) may also be present in their working environments. Inhalation of biological dusts, which are composed of organic material from straw, hay, animals, and microbes, can cause changes in pulmonary function, induce antibody formation and lead to the development of respiratory disease.

OBJECTIVE To evaluate interaction of HLA-DPβ1 and DRβ1 polymorphisms with metrics of beryllium exposure, in the development of beryllium sensitization (BeS) and chronic beryllium disease (CBD). METHODS A matched case-control study of 61 CBD, 41 BeS, and 259 controls from two beryllium-processing facilities. RESULTS BES and CBD were significantly associated with presence of DPβE69. Dose response of exposure was not observed for the development of BES and CBD with/without adjustment for DPβE69 (p > 0.05). The DRβE71 polymorphism was more common in BeS than CBD after adjusting for exposure and maybe a protective factor (aOR 0.4, 95% CI 0.2-0.9) against the progression of BeS to CBD. CONCLUSION No exposure-response association was found, which may reflect that the workers in this high exposure cohort were above a threshold level where an exposure-response could be observed.

OBJECTIVE Research suggests military environmental exposure concerns are associated with negative health outcomes. This study investigated the relationship among exposure concerns, PTSD, and somatic symptoms to enhance post-deployment health care programs for veterans. METHODS We analyzed intake health data from a heterogeneous sample of predominantly Operation Desert Storm/Shield and Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) veterans (N = 247). RESULTS Individual exposure concerns and somatic symptoms were each associated with higher PTSD symptom severity. Regression modelling demonstrated total exposure concerns and PTSD symptom severity linked with total somatic symptom severity. Mediation modelling revealed PTSD symptom severity to partially explain the relation between exposure concerns and somatic symptoms. CONCLUSIONS These findings illustrate the need for integrative treatment approaches incorporating physiological and exposure-related concerns associated with PTSD among veterans.

OBJECTIVE To determine personal, injury and scheme factors are associated with experiencing stressful healthcare provider (HCP) interactions, and to determine impact of stressful HCP interactions on return to work (RTW). METHODS Using the 2018 National RTW Survey of 4,574 injured workers that submitted a workers' compensation claim, multivariable logistic regression determined factors associated with stressful HCP interactions (recorded as "a bit stressful" to "extremely stressful") and RTW (self-reported yes/no at interview). RESULTS Workers claiming for mental illness, who found healthcare difficult to access, who consulted with multiple HCPs, and who experienced psychological or financial stress, were significantly more likely to experience stressful HCP interactions. Stressful HCP interactions were associated with lower odds of RTW. CONCLUSIONS Findings provide impetus to investigate why HCP interactions are stressful to enable efforts to reduce stress, possibly improving RTW outcomes.

OBJECTIVE This study investigates the injury, socio-demographic, workplace and temporal characteristics related with Gradual Return to Work (RTW) among workers with a work-acquired musculoskeletal disorder in British Columbia, Canada. METHODS Accepted workers' compensation lost-time claims were extracted between 2010 and 2015 (n = 141 490). A multivariable logistic regression model was used to analyze the determinants of Gradual RTW. RESULTS Within one year after injury, 41.0% of workers had at least one day of Gradual RTW. Serious injury severity, female gender, increasing age, wage, and firm size, longer sickness absence, and recent previous claims increased the proportion of workers being provided with Gradual RTW. CONCLUSION Consideration of injury, socio-demographic, workplace and temporal variability in the provision of Gradual RTW can identify inequalities in the provision and increase effective use of Gradual RTW for workers with musculoskeletal disorders.

OBJECTIVE This study examined the relationship between long working hours, rest breaks, and work-related injuries. METHODS A total of 25,439 employees were examined from the 4th Korean Working Conditions Survey. Rest breaks were divided into two groups and working hours were divided into four groups. Multiple logistic regression was conducted to estimate the relationship between long working hours, rest breaks, and work-related injuries. RESULTS Work-related injuries were significantly associated with long working hours. Stratified by rest breaks, the risk of work-related injuries increased with increasing working hours in a dose-response pattern among those with insufficient rest breaks, while the risk was not significant among those with sufficient rest breaks. CONCLUSION It is important to provide sufficient rest breaks to prevent work-related injuries among workers with long working hours.

OBJECTIVE This study was to investigate the acute effects of hand-arm vibrations on the nerve functions of the hands, and the impact of the grip force applied to the vibrating tool during exposure. METHODS Grip strength and perception of vibration, touch, and temperature were evaluated using QST before and after vibration exposure in 21 occupationally unexposed individuals. The procedure was performed twice, with a higher grip force being applied during exposure on the second occasion. RESULTS Vibration perception was significantly impaired after both exposures. Grip strength, perception of touch and temperature were only significantly affected after the high grip force exposure. CONCLUSIONS Exposure to hand-arm vibrations has acute effects on hand nerve function that are sensitive to the grip force applied during exposure.
