Objectives: N95 or Type II filtering face pieces (FFP2) are often worn during work hours or on public transportation to prevent airborne infection. The aim of this randomized controlled crossover study is to assess the impact of FFP2 induced breathing resistance on pulmonary function, blood gas values and discomfort during walking and stair climbing.

Methods: N = 16 healthy adults (24.8 ± 2.2 years; 10 females, ) participated. Interventions included (1) six minutes of walking in a 16-meter-long hallway (612 m) and (2) eight minutes of stair climbing in a two-story staircase (420 stairs), both with and without a FFP2 (> 48 h wash-out). Spiroergometric data (Ventilation, breathing frequency, tidal volume, oxygen uptake and carbon dioxide exhalation (primary outcome), end tidal carbon dioxide- and oxygen pressure) and self-reported response (Perceived exertion, dyspnoea and pain) were assessed during activities. Blood gas analysis (capillary carbon dioxide- (pCO₂) (primary outcome) and oxygen partial pressure (pO₂), pH, lactate and base excess) was measured immediately after cessation of activities. Manipulation effects (FFP2 versus no mask) were tested using repeated measures analyses of variance.

Results: Analysis showed no effect of FFP2 on pCO₂ or other blood-gas parameters but on carbon dioxide exhalation during walking: (mean 1067, SD 209 ml/min) (mean 1908, SD 426 ml/min) (F(15) = 19.5; p < 0.001; η_p² = 0.566) compared to no mask wearing (mean 1237, SD 173 ml/min; mean 1908, SD 426 ml/min). Ventilation was decreased and dyspnoea was increased by FFP2 during activities. FFP2 led to lower oxygen uptake and lower end tidal oxygen but higher end tidal carbon dioxide during stair climbing.

Conclusions: FFP2 decreased ventilation based on slower breathing patterns and led to limitations in pulmonary gas exchange and increased subjective dyspnoea. However, invasive diagnostics revealed no signs of clinically relevant metabolic effects immediately after everyday physical activities.

Background: Hybrid working arrangements that combine remote and office work are on the rise. Although hybrid work has been associated with mental health benefits in employees, challenges in the transformation to hybrid persist particularly in public administration organizations which have been connected to a pronounced culture of presence and inadequate technical infrastructure. Further evidence on the link between hybrid working conditions and employee health is needed. To support the establishment of healthy hybrid working conditions, this study aims to identify employees' job demands, resources and support needs in public administration.

Methods: Semi-structured interviews were conducted with N = 13 employees who work hybrid in public administration organizations in Northern Germany between February and May 2023. Interviewees were asked about their perceived job demands, resources, and support needs in hybrid work. The data was analyzed in a deductive-inductive approach of qualitative content analysis, primarily supported by the job demands-resources model as a theoretical framework.

Results: Several job demands, e.g., an increase in work and meetings, and resources such as personal freedom and responsibility, were identified in the context of hybrid work. A multitude of the reported job resources and demands relate to work organization and social relationships. The results disclose discrepancies between participants' experiences of job demands and resources, underlining the subjectivity of employees' perceptions of hybrid working conditions. Interviewees' support needs for hybrid work also varied, encompassing structural-level aspects such as increased acceptance and promotion of hybrid work in the organization as well as behavioral-level aspects, for instance, strategies and self-discipline for boundaries and structure.

Conclusions: This study provides a first comprehensive overview of the job demands, resources and support needs in hybrid work in public administration. This study builds an important basis for further research to understand the impact of hybrid working conditions on health-related employee outcomes. The identified support needs provide a valuable point of reference for health-promoting hybrid working conditions which public administration employers should begin establishing as early as possible in the ongoing transition to hybrid work.

Background: In a previous study from 2018, 38 wheel loader assembly workers were examined, showing high exposures to transient and high-frequency vibrations. After the investigation, preventive measures were immediately implemented to reduce the vibration exposure. In 2022, a follow-up study was carried out to examine the effect of these measures.

Methods: The follow-up study included 35 (27 men and 8 women) of the original 38 workers. They were divided into two groups, 24 workers with ongoing vibration exposure and 11 workers, not vibration exposed since 2018. All participants completed a questionnaire and underwent a thorough examination, including several neurophysiological tests and a comprehensive assessment of musculoskeletal symptoms. The questionnaire responses and on-site vibration level measurements formed the basis for the individual vibration exposure assessment.

Results: In 2018, clear differences were noted between the two groups regarding vibration perception thresholds (VPT), needle test, 2-PD (2-point discrimination), and monofilament test with deviating results in the unexposed group. The difference between the two groups was significantly smaller at the follow-up examination in 2022, where differences remained for VPT and monofilament tests, with deviating test results in the unexposed group. When comparing variable values between 2018 and 2022 within the exposed and unexposed groups, respectively, the unexposed group showed mostly unchanged values, while a deterioration was observed for VPT, needle test and temperature sensitivity test among the exposed workers during follow-up. The prevalence of VWF (Vibration white fingers) was around 30-40% and neuropathy around 75% among exposed workers during follow-up compared to about 60% and 85% respectively, in the unexposed group.

Conclusion: The overall categorization of white fingers and neuropathy, according to the Stockholm Workshop Scale, remained largely unchanged in both study groups from 2018 to 2022. The introduction of cost-effective and relatively simple preventive measures may have contributed to this result. Throughout the follow-up period, the number of exposed workers who developed musculoskeletal disorders and newly reported cases of vibration injuries at the factory decreased. Without this preventive program, increased vascular and nerve symptoms would most likely have occurred during follow-up due to continued vibration exposure.

Background: Lead is one of the most nonessential toxic heavy metal agents found in automotive garages. The occupational exposure of garage workers to lead commonly poses acute and chronic health risks that can be prevented. In Ethiopia, there have been limited studies on lead exposure among garage workers, who overemphasize exposure to lead. This study aimed to assess occupational blood lead levels and associated factors in garage workers using a cross-sectional comparative design.

Methods: A comparative cross-sectional study design was used to compare the occupational blood lead levels of 36 randomly selected garage workers and 34 office workers who were matched by age and sex. Blood specimens were collected by trained medical laboratory experts. The collected blood samples were tested in a certified laboratory using a microwave plasma atomic emission spectrometry (MP-AES) device at a wavelength of 405.78 nm. Excel and SPSS Version 26 were used for data management and analysis, respectively.

Results: The mean (SD) age of the exposed group was 39.0 (7.5) years, whereas the mean age of the unexposed group was 38.0 (6.1) years. The occupational mean (SD) blood-lead-level in the exposed groups was 29.7 (12.2) µg/dl, compared to 14.8 (9.9) µg/dl among the unexposed groups. The mean blood-lead level among the exposed workers was significantly different from that among the unexposed workers (P < 0.01). Of all the study participants, only 22.2% of the exposed groups had blood lead levels higher than the World Health Organization's recommended limit of 40 µg/dl. The main significant predictors of occupational blood-lead-level exposure among workers were extra working hours, service years, and having a previous (prior) employment history in a garage. The occupations of the two groups did not significantly differ in terms of blood-lead levels (p > 0.05).

Conclusions: The BLL of the Garage workers was significantly greater than that of the Non-Garage workers. Hence, it is advised that garage management should encourage workers to use exposure prevention methods, such as washing their hands before eating and taking showers after the completion of work, by providing regular occupational safety training.

Background: Research on cannabis use motives has focused on youth. Little is known about motives among working adults, including how work may play a role. This study aimed to describe cannabis use motives and their connection to work, and identify the personal and work correlates of work-related motives among a sample of workers.

Methods: A national, cross-sectional sample of Canadian workers were queried about their cannabis use. Workers reporting past-year cannabis use (n = 589) were asked their motives for using cannabis and whether each motive was related to work or helped them manage at work (i.e., work-related). Multinomial logistic regression analyses were conducted to estimate the associations of personal and work characteristics with work-related cannabis use motives (no work-related motives, < 50% of motives work-related, ≥ 50% of motives work-related).

Results: Use for relaxation (59.3%), enjoyment (47.2%), social reasons (35.3%), coping (35.1%), medical reasons (30.9%), and sleep (29.9%) were the most common motives. Almost 40% of respondents reported one or more of their cannabis use motives were work-related, with coping (19.9%) and relaxation (16.3%) most commonly reported as work-related. Younger age, poorer general health, greater job stress, having a supervisory role, and hazardous work were associated with increased odds of reporting at least some cannabis use motives to be work-related, while work schedule and greater frequency of alcohol use were associated with reduced odds of motives being primarily work-related.

Conclusions: Cannabis use motives among workers are diverse and frequently associated with work. Greater attention to the role of work in motivating cannabis use is warranted.

Background: This study aimed to examine time trends in physical working conditions across and within occupational groups in Germany between 2006 and 2018.

Methods: Logistic regression analyses were conducted using data from the BIBB/BAuA Employment Surveys in 2006, 2012, and 2018, with a total sample size of 59,006 participants. The study investigated changes in various self-reported occupational exposure measures over time, along with demographic shifts in the workforce.

Results: The results showed overall improvements in most occupational exposure measures during the study period, alongside an aging and upskilling workforce. However, exposure to awkward postures, microorganisms, and, to a lesser extent, noise increased. Substantial variation was observed between occupational groups, with more favourable trends among white-collar high-skilled and blue-collar low-skilled workers, and less favourable trends among white-collar low-skilled and blue-collar high-skilled workers.

Conclusions: While trends in physical working conditions in Germany are partly promising, some exposures are worsening, and substantial inequalities between occupations persist. As occupational exposures remain common, there is still a need for targeted interventions to improve working conditions, particularly in higher-risk occupations.

Background: In previous studies a moderator effect of management position could be found between Person-environment fit of masculinity, and burnout. Present study goals are to analyze previous fundings of the importance of the individual gender-role in relation to the work environment in more detail.

Methods: In this cross sectional explanative study, an online survey took place using Gender Role Orientation Scale (GTS +) by Altstötter-Gleich and DearEmployee-Survey by Wiedemann et al. The sample consists of 891 participants-516 female (58%), 373 male (42%), among those 277 executives (32%) and 594 participants without managerial responsibility (68%), age 17-70 years (M = 29.86; S = 7.67). Four groups were divided according to P-E fit in femininity and P-E fit in masculinity, this enabled a more precise distinction between the participants. The proportions of executives were determined, and compared in each group by a ${\chi }^2$ -Test Hierarchical linear regression models predicting burnout and proving moderator effects of managerial position were calculated for each group.

Results: The proportions of executives were the highest in the two groups with participants, who had a higher individual masculinity compared to their work environment. A moderator effect of managerial position between P-E fit in masculinity and burnout was found in group "Indifferent" (participants with lower feminity and masculinity compared with work environment). With a worse P-E fit in masculinity burnout values rise for individuals with no managerial position. On the other hand, among leaders burnout values decrease a worse P-E fit in masculinity.

Conclusions: People with a high individual masculinity compared to work environment tend more to be selected as managers, regardless of the individual characteristics of femininity, which may generally lead to a highly masculine and less feminine leadership and corporate culture. This culture could increase burnout risk for people with low individual masculinity and high feminity scores compared to work environment as well as for persons with low individual masculinity and feminity compared to work environment, especially if they are not in a managerial position.

Background: Migraine is common and can be highly disabling. Adequate migraine self-management (SM) can mitigate the potentially adverse health effects of migraine. However, adequate SM can be challenging to implement in everyday life, for instance, at the workplace. We aimed to explore how migraine SM is carried out at work and which occupational factors may determine effective implementation according to employees with migraine. We also explored the potential impact of the COVID-19 pandemic and the associated re-arrangement of working conditions on migraine SM at work.

Methods: We conducted semi-structured qualitative interviews (08/2020-01/2021). Participants were eligible if they have worked for at least six months with a minimum of twenty hours per week and with a migraine diagnosis. The interviews were transcribed and content-analyzed using MAXQDA.

Results: Migraine SM was perceived to be influenced by social interactions at work (e.g., in terms of understanding vs. stigmatization), the level of job decision latitude (JDL, i.e., the extent to which one is able to influence work processes, e.g., when working from home), and workplace design (e.g., in terms of opportunities to withdraw from work). During the COVID-19 pandemic, especially increased JDL appeared to favorably influence migraine SM.

Conclusions: Migraine SM at work is fostered or complicated by various psychosocial working conditions. By considering these facilitators and barriers, more migraine-friendly workplaces can be created.

Background: Latex gloves are essential for protecting healthcare workers from biological hazards but pose a risk of latex allergy, particularly due to powdered, protein, and allergen content. Recent advancements in latex glove manufacturing have led to reduced levels of extractable proteins, a known factor triggering allergenic reaction. This study aimed to compare latex sensitization between nursing staff using low-protein and high-protein latex gloves at a tertiary university hospital in Thailand.

Methods: A cross-sectional analytical study categorized participants into two groups based on glove exposure: the low extractable protein group (only exposed to non-powdered latex gloves with extractable protein levels below 50 µg/g) and the high extractable protein group (exposed to powdered latex gloves with levels above 50 µg/g). The sample size comprised 163 individuals in the low protein group and 318 in the high protein group (1:2). Latex allergy symptoms and sensitization were assessed using a self-administered questionnaire and latex-specific IgE measurement (ImmunoCAP), respectively. Data analysis involved descriptive and inferential statistics, including odds ratios and 95%CI.

Results: Demographic data was mostly similar in both exposure groups except for age. No significant differences in latex sensitization between the low and high protein groups were found via latex-specific IgE measurement (crude OR 1.90, 95%CI: 0.5, 7.18), potentially attributed to lower extractable protein levels in powdered latex gloves compared to previous studies. In contrast, the low protein group exhibited significantly fewer current latex allergy symptoms in both bivariate (crude OR 0.24, 95%CI: 0.06, 0.74) and multiple variable analysis (adjusted OR 0.18, 95%CI: 0.04, 0.86). Moreover, there was a significant reduction in latex allergy symptoms among the low protein group, decreasing from 9.8% who reported experiencing symptoms (when powdered latex gloves were used) to 1.2% who still reported current symptoms (OR 0.11, 95%CI: 0.02, 0.44).

Conclusions: This study underscores the importance of using non-powdered and low-protein latex gloves to reduce latex allergy symptoms while emphasizing the need for further investigation into the relationship between extractable protein levels in addition to the attempt of the major allergen removal and latex sensitization amid evolving glove manufacturing practices.
