Comparative study of virus and lymphocyte distribution with clinical data suggests early high dose immunosuppression as potential key factor for the therapy of patients with BoDV-1 infection.

ABSTRACTBorna disease virus 1 (BoDV-1) was just recently shown to cause predominantly fatal encephalitis in humans. Despite its rarity, bornavirus encephalitis (BVE) can be considered a model disease for encephalitic infections caused by neurotropic viruses and understanding its pathomechanism is of utmost relevance. Aim of this study was to compare the extent and distribution pattern of cerebral inflammation with the clinical course of disease, and individual therapeutic procedures. For this, autoptic brain material from seven patients with fatal BVE was included in this study. Tissue was stained immunohistochemically for pan-lymphocytic marker CD45, the nucleoprotein of BoDV-1, as well as glial marker GFAP and microglial marker Iba1. Sections were digitalized and counted for CD45-positive and BoDV-1-positive cells. For GFAP and Iba1, a semiquantitative score was determined. Furthermore, detailed information about the individual clinical course and therapy were retrieved and summarized in a standardized way. Analysis of the distribution of lymphocytes shows interindividual patterns. In contrast, when looking at the BoDV-1-positive glial cells and neurons, a massive viral involvement in the brain stem was noticeable. Three of the seven patients received early high-dose steroids, which led to a significantly lower lymphocytic infiltration of the central nervous tissue and a longer survival compared to the patients who were treated with steroids later in the course of disease. This study highlights the potential importance of early high-dose immunosuppressive therapy in BVE. Our findings hint at a promising treatment option which should be corroborated in future observational or prospective therapy studies.ABBREVIATIONS: BoDV-1: Borna disease virus 1; BVE: bornavirus encephalitis; Cb: cerebellum; CNS: central nervous system; FL: frontal lobe; GFAP: glial fibrillary acid protein; Hc: hippocampus; Iba1: ionized calcium-binding adapter molecule 1; Iba1act: general activation of microglial cells; Iba1nod: formation of microglial nodules; IL: insula; Me: mesencephalon; Mo: medulla oblongata; OL: occipital lobe; pASS: per average of 10 screenshots; patearly: patients treated with early high dose steroid shot; patlate: patients treated with late or none high dose steroid shot; Po: pons; So: stria olfactoria; Str: striatum.

Health-oriented leadership, gender-differences and job satisfaction: results from a representative population-based study in Germany.

BACKGROUND: In recent years, the topic of health-oriented leadership (HoL) has often been investigated with health-related outcomes like general health, strain, depression, and anxiety symptoms. In contrast, research which considers the gender of leaders and employees in connection to HoL as well as studies on relationships between HoL and job satisfaction, are scarce. The aim of this paper is to explore the relationships between HoL and health status assessed by employees and leaders, to analyse the relationships between HoL and job satisfaction as a non-health-related outcome for employees and leaders and to examine differences in the assessment of HoL between men and women in a representative dataset of the working population in Germany. METHODS: Data were collected via an access panel as a cross-sectional survey. The quota sample included 643 German workers (managers and employees). We focused on staff-care as a core component of HoL. Statistical analyses were performed using Pearson correlations and regression analyses as well as t-tests and Mann-Whitney-U-Tests. RESULTS: The results showed no significant differences between male and female employees or leaders in assessing HoL. Regarding HoL we found relationships between self-rated health status or job satisfaction, both for the self-rated assessment of leaders and employees. CONCLUSIONS: Our findings indicate relationships between HoL and well-being as well as job satisfaction at the workplace. For interventions of any kind, the lack of gender effects leaves a wide scope for the implementation of health-promoting measures. In particular, the findings on the relationship between HoL and job satisfaction through leaders' self-assessment could be used for salutogenic approaches to strengthen resources in leadership trainings.
