Measuring family influence from the non-family employee perspective: The perceived family influence scale (PFIS)

To further our understanding of family influence in family businesses, this study introduces the Perceived Family Influence Scale (PFIS). Departing from existing owner-centric methodologies, the PFIS uses social constructivism theory to capture family influence from the perspective of non family employees, a frequently neglected but integral stakeholder group within the family firm ecosystem. Following a rigorous multistep development process involving 600 non-family employees, we validate the PFIS and identify three core sub-dimensions of perceived family influence: culture, organizational decision-making, and image. We also demonstrate the practical applicability of the PFIS by examining the link between perceived family influence and non-family employee job satisfaction. Grounded in social constructivism, the PFIS is a reliable instrument that allows for the collection of more unbiased and holistic data on family influence, thereby refining our understanding of family firms and advancing the family business research field

CNS demyelinating events in primary Sjogren's syndrome: A single-center case series on the clinical phenotype

ObjectiveThe study aimed to assess the prevalence, clinical characteristics, and therapeutic outcomes of the central nervous system (CNS) demyelinating disease in a large cohort of primary Sjogren's syndrome (pSS). MethodsThis is an explorative cross-sectional study of patients with pSS seen in the departments of rheumatology, otorhinolaryngology, or neurology of a tertiary university center between January 2015 and September 2021. ResultsIn a cohort of 194 pSS patients, 22 patients had a CNS manifestation. In this CNS group, 19 patients had a lesion pattern suggestive of demyelination. While there were no obvious differences in the patients' epidemiological disposition or rate of other extraglandular manifestations, the CNS group differed from the remaining patients with pSS by having less glandular manifestations but a higher seroprevalence for anti-SSA/Ro antibodies. Notably, patients with CNS manifestations were often diagnosed with multiple sclerosis (MS) and treated as such, although age and disease course were atypical of MS. Many first-line MS agents were ineffective in these MS look-alikes;however, the disease course was benign with B-cell-depleting agents. ConclusionNeurological symptoms of pSS are common and clinically manifest mainly as myelitis or optic neuritis. Notably, in the CNS, the pSS phenotype can overlap with MS. The prevailing disease is crucial since it has a major impact on the long-term clinical outcome and the choice of disease-modifying agents. Although our observations neither confirm pSS as a more appropriate diagnosis nor rule out simple comorbidity, physicians should consider pSS in the extended diagnostic workup of CNS autoimmune diseases

Fiskalische Wirkungen der Einführung eines gesetzlichen Mindestlohns

Der BMAS Forschungsbericht "Fiskalische Wirkungen der Einführung eines gesetzlichen Mindestlohns" quantifiziert die mindestlohnbedingten Veränderungen von Einnahmen- und Ausgaben des öffentlichen Gesamthaushalts, also im Steuer- und Transfersystem sowie auf der Ebene der Gesetzlichen Sozialversicherungen. Ausgangspunkt für die Berechnungen stellt ein Literaturüberblick zum aktuellen Stand der quantitativ orientierten Forschung zu den Wirkungen des gesetzlichen Mindestlohns in Deutschland dar. Die durchgeführten Berechnungen erfolgen dann mit Hilfe des Mikrosimulationsmodells der Prognos auf Basis der Daten des sozio-oekonomischen Panels. Zur Abgrenzung mindestlohninduzierter Lohneffekte werden im Datensatz verschiedene Beschäftigtengruppen identifiziert. Für diese Gruppen werden kontrafaktische Stundenlöhne und Arbeitszeiten bestimmt, die als Grundlage für die Modellrechnungen "ohne Mindestlohn" genutzt werden. Abschließend erfolgt die Abschätzung der Mindestlohneffekte auf die fiskalischen Einnahmen und Ausgaben für unterschiedliche Szenarien, um die mögliche Spannbreite der Effekte aufzuzeigen.The BMAS research report "Fiscal Effects of the Introduction of a Statutory Minimum Wage" quanti-fies the minimum wage-related changes in income and expenditure in the overall public budget, i.e. in the tax and transfer system and the statutory social insurance scheme. The starting point for these calculations is an overview of the literature on the latest quantitative research into the impact of the statutory minimum wage in Germany. The calculations are then carried out with the help of Prognos‘ microsimulation model based on data from the Socio-Economic Panel. In the data set, various em-ployee groups are identified to differentiate minimum wage effects. Counterfactual hourly wages and working hours are determined for these groups, which are then used as the basis for the "without minimum wages" model calculations. Finally, the minimum wage effects on fiscal income and ex-penditure are estimated for different scenarios to show the possible range of effects

Increased interleukin-26 in the peripheral joints of patients with axial spondyloarthritis and psoriatic arthritis, co-localizing with CD68-positive synoviocytes

Objectives: IL26 levels are elevated in the blood and synovial fluid of patients with inflammatory arthritis. IL26 can be produced by Th17 cells and locally within joints by tissue-resident cells. IL26 induces osteoblast mineralization in vitro. As osteoproliferation and Th17 cells are important factors in the pathogenesis of axial spondyloarthritis (axSpA), we aimed to clarify the cellular sources of IL26 in spondyloarthritis. Methods: Serum, peripheral blood mononuclear cells (n = 15–35) and synovial tissue (n = 3–9) of adult patients with axSpA, psoriatic arthritis (PsA) and rheumatoid arthritis (RA) and healthy controls (HCs, n = 5) were evaluated by ELISA, flow cytometry including PrimeFlow assay, immunohistochemistry and immunofluorescence and quantitative PCR. Results: Synovial tissue of axSpA patients shows significantly more IL26-positive cells than that of HCs (p < 0.01), but numbers are also elevated in PsA and RA patients. Immunofluorescence shows co-localization of IL26 with CD68, but not with CD3, SMA, CD163, cadherin-11, or CD90. IL26 is elevated in the serum of RA and PsA (but not axSpA) patients compared with HCs (p < 0.001 and p < 0.01). However, peripheral blood CD4+ T cells from axSpA and PsA patients show higher positivity for IL26 in the PrimeFlow assay compared with HCs. CD4+ memory T cells from axSpA patients produce more IL26 under Th17-favoring conditions (IL-1β and IL-23) than cells from PsA and RA patients or HCs. Conclusion: IL26 production is increased in the synovial tissue of SpA and can be localized to CD68+ macrophage-like synoviocytes, whereas circulating IL26+ Th17 cells are only modestly enriched. Considering the osteoproliferative properties of IL26, this offers new therapeutic options independent of Th17 pathways

Seroprevalence of Schmallenberg virus infection in sheep and goats flocks in Germany, 2012-2013

Schmallenberg virus (SBV) is a member of the family Bunyaviridae and mainly affects ruminants. It is transmitted by biting midges, first and foremost Culicoides spp., and causes congenital malformations reflected in arthrogryposis-hydranencephaly (AH) syndrome. The aim of this study was to collect data on the emergence of SBV as a new arthropod-borne disease introduced into Europe in 2011. Germany was located in the core region of the 2011/2012 epidemic. Following two seroprevalence studies in the north-west of Germany in 2012, this study focused on the epidemiology and distribution of SBV throughout 130 small ruminant flocks in the whole country. Blood samples were obtained of 30 animals per flock and a SBV-specific questionnaire was used to collect operating data of the farms. The median within-herd seroprevalence for all 130 flocks tested was 53.3% with a total range from 0% to 100%. The median within-herd seroprevalence for goats was 30% [interquartile range (IQR): 40.3%] and 57% for sheep (IQR: 43.3%). Small ruminant flocks kept permanently indoors or housed overnight had a significantly lower seroprevalence than flocks kept permanently outdoors. In addition, this study revealed a significantly lower seroprevalence in the north-east of Germany. These results show that small ruminants in Germany are still at risk of contracting new SBV infections following incomplete seroconversion of flocks especially in the north-east of Germany. This might contribute to SBV becoming enzootic in central and northern Europe. Furthermore, the survey revealed that housing animals at least during mating and early pregnancy may reduce the risk of new SBV infections and may thus be an option to reduce losses as long as there is no licensed vaccine available on the German market

Worsening calcification propensity precedes all-cause and cardiovascular mortality in haemodialyzed patients

A novel in-vitro test (T-50-test) assesses ex-vivo serum calcification propensity which predicts mortality in HD patients. The association of longitudinal changes of T-50 with all-cause and cardiovascular mortality has not been investigated. We assessed T-50 in paired sera collected at baseline and at 24 months in 188 prevalent European HD patients from the ISAR cohort, most of whom were Caucasians. Patients were followed for another 19 [interquartile range: 11-37] months. Serum T-50 exhibited a significant decline between baseline and 24 months (246 +/- 64 to 190 +/- 68 minutes;p < 0.001). With serum Delta-phosphate showing the strongest independent association with declining T-50 (r = -0.39;p < 0.001) in multivariable linear regression. The rate of decline of T-50 over 24 months was a significant predictor of all-cause (HR = 1.51 per 1SD decline, 95% CI: 1.04 to 2.2;p = 0.03) and cardiovascular mortality (HR = 2.15;95% CI: 1.15 to 3.97;p = 0.02) in Kaplan Meier and multivariable Cox-regression analysis, while cross-sectional T-50 at inclusion and 24 months were not. Worsening serum calcification propensity was an independent predictor of mortality in this small cohort of prevalent HD patients. Prospective larger scaled studies are needed to assess the value of calcification propensity as a longitudinal parameter for risk stratification and monitoring of therapeutic interventions

Development of a highly effective combination monoclonal antibody therapy against Herpes simplex virus.

BACKGROUND Infections with Herpes simplex virus (HSV)-1 or -2 usually present as mild chronic recurrent disease, however in rare cases can result in life-threatening conditions with a large spectrum of pathology. Monoclonal antibody therapy has great potential especially to treat infections with virus resistant to standard therapies. HDIT101, a humanized IgG targeting HSV-1/2 gB was previously investigated in phase 2 clinical trials. The aim of this study was to develop a next-generation therapy by combining different antiviral monoclonal antibodies. METHODS A lymph-node derived phage display library (LYNDAL) was screened against recombinant gB from Herpes simplex virus (HSV) -1 and HDIT102 scFv was selected for its binding characteristics using bio-layer interferometry. HDIT102 was further developed as fully human IgG and tested alone or in combination with HDIT101, a clinically tested humanized anti-HSV IgG, in vitro and in vivo. T-cell stimulating activities by antigen-presenting cells treated with IgG-HSV immune complexes were analyzed using primary human cells. To determine the epitopes, the cryo-EM structures of HDIT101 or HDIT102 Fab bound to HSV-1F as well as HSV-2G gB protein were solved at resolutions < 3.5 Å. RESULTS HDIT102 Fab showed strong binding to HSV-1F gB with Kd of 8.95 × 10-11 M and to HSV-2G gB with Kd of 3.29 × 10-11 M. Neutralization of cell-free virus and inhibition of cell-to-cell spread were comparable between HDIT101 and HDIT102. Both antibodies induced internalization of gB from the cell surface into acidic endosomes by binding distinct epitopes in domain I of gB and compete for binding. CryoEM analyses revealed the ability to form heterogenic immune complexes consisting of two HDIT102 and one HDIT101 Fab bound to one gB trimeric molecule. Both antibodies mediated antibody-dependent phagocytosis by antigen presenting cells which stimulated autologous T-cell activation. In vivo, the combination of HDIT101 and HDIT102 demonstrated synergistic effects on survival and clinical outcome in immunocompetent BALB/cOlaHsd mice. CONCLUSION This biochemical and immunological study showcases the potential of an effective combination therapy with two monoclonal anti-gB IgGs for the treatment of HSV-1/2 induced disease conditions
