XPD stalled on cross-linked DNA provides insight into damage verification.

The superfamily 2 helicase XPD is a central component of the general transcription factor II H (TFIIH), which is essential for transcription and nucleotide excision DNA repair (NER). Within these two processes, the helicase function of XPD is vital for NER but not for transcription initiation, where XPD acts only as a scaffold for other factors. Using cryo-EM, we deciphered one of the most enigmatic steps in XPD helicase action: the active separation of double-stranded DNA (dsDNA) and its stalling upon approaching a DNA interstrand cross-link, a highly toxic form of DNA damage. The structure shows how dsDNA is separated and reveals a highly unusual involvement of the Arch domain in active dsDNA separation. Combined with mutagenesis and biochemical analyses, we identified distinct functional regions important for helicase activity. Surprisingly, those areas also affect core TFIIH translocase activity, revealing a yet unencountered function of XPD within the TFIIH scaffold. In summary, our data provide a universal basis for NER bubble formation, XPD damage verification and XPG incision.

The prevalence of effort-reward imbalance and its associations with working conditions, psychosocial resources and burden among health care workers during the COVID-19 pandemic: Results of the egePan-Voice study.

OBJECTIVE: The association between a measure of effort-reward imbalance (ERI) and profession as well as gender in a sample of health care workers (HCW) during the first wave of the COVID-19 pandemic in Germany using the egePan-Voice study. In addition, we examined, which factors are associated with an effort-reward imbalance ratio (ERI ratio) >1. METHODS: In a large sample of HCW (N = 6174) we assessed occupational stress with the short version of the effort-reward imbalance (ERI) questionnaire, working conditions, COVID-19-related problems and psychosocial resources (ENRICHD Social Support Inventory, ESSI; Sense of Coherence Scale, SOC-3 and optimism, SOP2). RESULTS: The prevalence of a ERI ratio >1 among HCW was 50.9%. The prevalence's of an ERI ratio >1 were statistically significant different between gender as well as the occupational profession. The proportion of women (51.8%) with ERI ratio >1 was significantly higher than among men (47.8%). The highest ERI imbalance was found among nurses (62.8%), followed by medical technical assistants (MTA) (58.8%), while psychologists/psychotherapists revealed the lowest value (37.8%), followed by physicians (41.8%). In the total sample, most essential factors reported at this time for increased ERI ratio were: insufficient staff for the current work load, insufficient recovery, feeling insufficiently protected by measures taken by the hospital/the employer, high occupancy rate of the wards, insufficient trust in colleagues and being a nurse as compared with being a physician. CONCLUSION: The findings indicate a high proportion of HCW with effort-reward imbalance and substantial profession-related differences. Preventive interventions should be offered to vulnerable groups among the HCW to decrease the imbalance measured by work stress.

[Mobbing Among Hospital Physicians]. / Mobbing unter Klinikärztinnen und -ärzten.

OBJECTIVES: Bullying in the workplace is considered an interpersonal stress factor. Occupational stress and mental health among physicians is increasingly becoming the focus of public attention. The extent to which mobbing plays a role in this has hardly been investigated yet. The aim of this study is to provide data on the prevalence of bullying among hospital physicians in Germany and possible correlations with occupational stress and mental health. METHODS: Within the framework of two cross-sectional studies, 692 hospital physicians in the field of psychiatry/psychotherapy (P/PT) and 667 hospital physicians in intensive care (IM) were interviewed at conferences. Standardized questionnaires on mobbing experience, occupational stress and mental health (single item from COPSOQ, BDI-II, ERI, MBI) were used. RESULTS: Bullying was experienced by 4.6% (n=61) of the respondents. IM and women physicians were more often affected (not significant) and correlations with occupational stress (ERI), overcommitment (OC), emotional exhaustion (MBI) and depression (BDI-II) were found. CONCLUSION: Our data on a large cohort of physicians in specialties with different exposure profiles show that a relevant proportion is affected by bullying and that bullying is related to the experience of occupational stress as well as mental health impairments. From this, implications for institutional and individual prevention and support services can be derived.

[egePan-VOICE study on the psychosocial burden of the Covid-19 pandemic among - medical technical assistants]. / egePan-VOICE-Studie zur psychosozialen Belastung durch die Covid-19-Pandemie bei medizinischtechnischen Assistent*innen.

egePan-VOICE study on the psychosocial burden of the Covid-19 pandemic among - medical technical assistants Objectives: The Covid-19 pandemic is associated with increased demands on healthcare workers. A previously neglected occupational group is medical technical assistants (MTA). The aim is therefore to identify stress factors among MTA in Germany during the pandemic. Methods: A cross-sectional online survey of medical staff was conducted in spring 2020 (N = 8088). Results: N = 1483 records of MTA were analyzed. Retrospectively, the stress increased under the pandemic, and 60.1 % of MTA suffered from work stress (ERI). Staff shortages and extra work were associated with an increase in work stress. Problems of work-life balance and contact with contaminated material/infected persons favored stressful experiences. Conclusions: Some working conditions in the pandemic pose a potential health risk to MTA. It seems necessary to create improvements in the general conditions that enable healthily and effective work.

Psychosocial Impact of the COVID-19 Pandemic on Healthcare Workers and Initial Areas of Action for Intervention and Prevention-The egePan/VOICE Study.

INTRODUCTION: Epidemics lead to an increase in occupational stress and psychological strain among healthcare workers. However, the impact of a pandemic outbreak on healthcare systems is yet to be clearly defined. Therefore, this work aims to describe and analyze specific areas of workload among different groups of healthcare workers during the first wave of the COVID-19 pandemic. METHODS: A sample of N = 8088 persons working in the German-speaking healthcare sector participated in the VOICE/egePan online survey, which addressed the impact of the COVID-19 pandemic during the second quarter of 2020. We used 15 self-constructed items, based on the work of Matsuishi et al. (2012), to identify potential COVID-19-specific topics. RESULTS: N = 7542 records of healthcare workers were analyzed. Of these, 60.80% reported, retrospectively, an increase in stress since the outbreak of the pandemic. Problem areas tended to be indicated more frequently by the women surveyed than by the men. Nurses, paramedics and medical technicians reported the highest fear of infecting others while physicians reported the highest fear of physical or mental exhaustion. With respect to age, older respondents indicated less fear and felt more protected. Men and people living alone were more likely to use dysfunctional coping strategies. Migrants reported a higher fear of becoming infected or infecting others as well as they reported about increased levels of smoking. DISCUSSION: Retrospectively, the COVID-19 pandemic led to an increase in stress among healthcare workers. Problem areas have different focuses with regard to different living situations, environmental conditions and professions. In order to lay the best basis for healthy and efficient work, it seems necessary to take measures especially tailored to the needs of different groups of healthcare workers.

The mediating role of COVID-19-related burden in the association between adverse childhood experiences and emotional exhaustion: results of the egePan - VOICE study.

Background: Adverse childhood experiences (ACEs) increase the risk for mental health problems. However, there is a lack of data targeting the role of ACEs for one of the most prevalent mental health problems in health-care professionals: burnout. Objective: We aimed to assess the relationship between ACEs and the core burnout dimension 'emotional exhaustion' (EE). As health-care professionals have been facing particular challenges during the COVID-19 pandemic, we furthermore aimed to assess the role of COVID-19 associated burden in the interplay between ACEs and EE. Methods: During the first lockdown in Germany, a total of 2500 medical healthcare professionals were questioned in a cross-sectional online survey. Questions targeted, among others, sociodemographics, ACEs, COVID-19-associated problems (e.g. increase of workload, worries about relatives and patients) and emotional exhaustion, measured by the respective dimension of the Maslach Burnout Inventory (MBI). Results: In German health-care professionals, ACEs were associated with a higher EE score. The number of experienced ACEs was associated with the majority of assessed COVID-19-associated problems. An increasing number of ACEs predicted higher EE scores, controlling for gender. The association between ACEs and EE was mediated significantly by COVID-19-associated problems. These included maladaptive coping strategies such as increased smoking, drinking and use of antidepressants/tranquilizers, feeling less protected by measures of the employee or the state, a greater feeling of being burdened by COVID-19-associated problems and greater exhaustion and sleep problems. Conclusion: Our findings suggest ACEs as significant risk factor for EE in German health-care professionals. The current pandemic means a significant burden that further pronounces this risk.

Antecedentes: Las experiencias adversas en la niñez (ACEs en sus siglas en inglés) aumentan el riesgo de problemas de salud mental. Sin embargo, faltan datos sobre el papel de las ACEs en uno de los problemas de salud mental más prevalentes en los profesionales de la salud: el agotamiento (burnout).Objetivo: Nuestro objetivo fue evaluar la relación entre las ACEs y la dimensión central del agotamiento 'agotamiento emocional' (AE). Dado que los profesionales de la salud se han enfrentado a desafíos particulares durante la pandemia de COVID-19, además nos propusimos evaluar el papel de la carga asociada a COVID-19 en la interacción entre las ACEs y la AE.Métodos: Durante la primera cuarentena en Alemania, se interrogó a un total de 2500 profesionales de la salud en una encuesta transversal en línea. Las preguntas fueron dirigidas, entre otros, a datos sociodemográficos, ACEs, problemas asociados a COVID-19 (por ejemplo, aumento de la carga de trabajo, preocupaciones sobre familiares y pacientes) y agotamiento emocional, medidos por la dimensión respectiva del Maslach Burnout Inventory (MBI).Resultados: En los profesionales sanitarios alemanes, las ACEs se asociaron con una puntuación de AE más alta. El número de ACEs experimentados se asoció con la mayoría de los problemas asociados a COVID-19 evaluados. Un mayor número de ACEs predijo puntuaciones de AE más altas, controlado por género. La asociación entre ACEs y AE fue mediada significativamente por problemas asociados con COVID-19. Estos incluyeron estrategias de afrontamiento desadaptativas, como fumar, beber y usar antidepresivos/tranquilizantes, sentirse menos protegido por las medidas del empleador o el estado, una mayor sensación de estar agobiado por los problemas asociados con COVID-19 y un mayor agotamiento y problemas de sueño.Conclusión: Nuestros hallazgos sugieren que las ACEs son un factor de riesgo significativo para la AE en los profesionales de la salud alemanes. La pandemia actual implica una carga importante que acentúa aún más este riesgo.

Effort-Reward-Imbalance, Burnout, and Depression Among Psychiatrists 2006 and 2016-Changes After a Legislative Intervention.

Background: Physicians, especially psychiatrists, have a high risk of job-related stress, and mental impairment. In our study we examined changes in private and occupational stress factors and mental health within a decade. The legislative reduction of physicians' working hours in Germany during this period made it possible to investigate the impact of working hours in particular. Methods: Questionnaires were administered at two psychiatrist meetings (2006 and 2016) about job and family situation, depressiveness, burnout and effort-reward imbalance. A total of N = 1,797 datasets were analyzed. Results: Working hours and free weekends were associated with mental health indices. Correlation analyses showed that a reduction in weekly working hours and working days at weekends was related to reduced scores for effort-reward-imbalance, burnout and depression. Conclusions: Our data show changes in workplace stress and mental health in psychiatrists in a decade in which a reduction in working hours has been required by law. These results can provide indications of effective prevention strategies in the professional context of physicians working in psychiatry.
