COVID-19 vaccination exacerbates ex vivo IL-6 release from isolated PBMCs.

Ex vivo culturing of isolated PBMCs from individuals vaccinated with the coronavirus disease 2019 (COVID-19) vaccine BNT162b1 revealed a pronounced T cell response in the presence of the receptor binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. The latter was 10-fold more pronounced than the ex vivo response of PBMCs from the same individuals to other common pathogen T cell epitope pools, suggesting COVID-19 vaccination to induce RBD-specific T cell responses and not to facilitate T cell (re)activity in general. In the current study we investigated whether COVID-19 vaccination long-lastingly affects plasma interleukin (IL)-6 concentrations, complete blood counts, ex vivo IL-6 and IL-10 secretion of PBMCs cultured under basal conditions or in the presence of concanavalin (Con) A and lipopolysaccharide (LPS), salivary cortisol and α-amylase, mean arterial pressure (MAP), heart rate (HR) as well as mental and physical health status. The study was initially designed to investigate whether the presence vs. absence of own pets during urban upbringing has protective effects against psychosocial stress-induced immune activation during adulthood. However, as COVID-19 vaccines were approved while the study was ongoing and as, therefore, both vaccinated and non-vaccinated individuals have been recruited, we were able to stratify our data set with respect to the COVID-19 vaccination status and to assess the long-lasting effects of COVID-19 vaccination on physiological immunological, cardiovascular and psychosomatic health parameters. This data is presented in the current study. We show that isolated PBMCs from individuals vaccinated against COVID-19 show a ~ 600-fold increase in basal and a ~ 6000-fold increase in ConA-induced proinflammatory IL-6 secretion, and a ~ 2-fold increase in basal and ConA-induced antiinflammatory IL-10 secretion, both in comparison with non-vaccinated individuals. In contrast, LPS-induced ex vivo IL-6 and IL-10 secretions were not affected by vaccination status, as were plasma IL-6 concentrations, complete blood counts, salivary cortisol and α-amylase, cardiovascular measures and psychosomatic health. In summary, our findings are of relevance for many clinical studies ran before/during the pandemic, clearly indicating that consideration of participants' vaccination status is critical, at least when assessing ex vivo PBMC functionality.

Genetics, shared environment, or individual experience? A cross-sectional study of the health status following SARS-CoV-2 infection in monozygotic and dizygotic twins.

Background: The clinical presentation of COVID-19 shows a remarkably broad spectrum of symptoms. Although studies with adult twins on SARS-CoV-2 infection are rare so far, the fact that there is a genetic component associated with the highly variable clinical outcomes of COVID-19 has already been highlighted in recent studies investigating potential candidate genes and polymorphisms. This is the first study of adult monozygotic (MZ) and dizygotic (DZ) twins concordantly affected by SARS-CoV-2 infection to estimate variances explained by genetic, shared, and individual environmental components of both somatic and psychological symptoms following SARS-CoV-2 infection. Materials and methods: Data were collected from 10 adult twin pairs (5 MZ, 5 DZ) in which both twins already had a SARS-CoV-2 infection. A self-designed questionnaire, the Barthel Index, and the Multidimensional Fatigue Inventory (MFI) were used to assess various symptoms and health status following SARS-CoV-2 infection. Intra-class correlations were calculated, and the Falconer formula was used to quantify and differentiate the percentages of genetic influences as well as common environment and personal experiences on the examined traits. In addition, potential factors influencing symptom burden were examined and discussed. Results: We found high estimated heritability for mental impairment after SARS-CoV-2 infection (h 2 = 1.158) and for general fatigue (h 2 = 1.258). For symptom burden, reduced activity, and reduced motivation the individual environment appears to have the strongest influence. Other fatigue symptoms are influenced by genetic effects which range between 42.8 and 69.4%. Conclusion: Both genetics and individual environment play a role in health status after SARS-CoV-2 infection-mental status could be influenced primarily by genetic make-up, whereas for symptom burden and certain fatigue dimensions, non-shared environment could play a more critical role. Possible individual factors influencing the course of the disease were identified. However, gene-environment interactions may still be a source of differences between twins, and the search for candidate genes remains crucial on the road to personalized medicine.

Is the Pandemic Wearing Us Out? A Cross-Sectional Study of the Prevalence of Fatigue in Adult Twins without Previous SARS-CoV-2 Infection.

During the pandemic, mental health was not only impaired in people after a SARS-CoV-2 infection, but also in people without previous infection. This is the first study on twins without prior SARS-CoV-2 infection to estimate the influence of genetic components and shared as well as individual environments on pandemic-associated fatigue. The study sample included 55 monozygotic and 45 dizygotic twin pairs. A total of 34.5% reported an increase in fatigue since the pandemic. A significant correlation was shown between the responses within monozygotic (χ2[1] = 11.14, p = 0.001) and dizygotic pairs (χ2[1] = 18.72, p < 0.001). In all pandemic-associated fatigue dimensions, individual environment (ranging from e2 = 0.64 to e2 = 0.84) and heritability (ranging from h2 = 0.32 to h2 = 1.04) seem to have the highest impact. The number of comorbidities significantly correlated with physical fatigue (Spearman's ρ = 0.232, p < 0.001) and psychological impairment due to pandemic measures with the total fatigue score (Spearman's ρ = 0.243, p < 0.001). However, calculated ANCOVAs with these significant correlations as covariates showed no significant influence on the mean values of the respective fatigue dimensions. Susceptibility to pandemic-associated fatigue may be genetically and environmentally determined, while intensity is also influenced by individual components. The prevalence of fatigue is high even in individuals without prior SARS-CoV-2 infection. Future mental health prevention and intervention programs should be implemented to alleviate the impact of the pandemic on the global population.

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.
