COVID-19 vaccination lowers SARS-CoV-2 infection risk independent of diabetes, cancer and smoking in SHIP-COVID cohort, Northern Germany Open
This study ( n = 668) investigated the effect of vaccination on SARS-CoV-2 infection among individuals with type 2 diabetes mellitus (T2DM), cancer, and smoking in a prospective cohort study in Northern Germany. Participants from the SHIP-…

Development and validation of a core genome multilocus sequence typing scheme for <i>Citrobacter freundii</i> : application in outbreak investigations and comparative analysis across the <i>Citrobacter</i> genus Open
Citrobacter freundii is a nosocomial pathogen increasingly associated with multidrug resistance and hospital outbreaks. Despite its growing clinical relevance, no standardized core genome multilocus sequence typing (cgMLST) scheme has been…

Platelet-activating histone/antihistone IgG complexes in anti-PF4–negative thrombosis and thrombocytopenia syndrome Open
Thrombosis and thrombocytopenia syndromes (TTS) describe immune-mediated thrombotic adverse reactions after vaccination against COVID-19. Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a well-known subentity of TTS, caused by…

Non-cross-reactive epitopes dominate the humoral immune response to COVID-19 vaccination – kinetics of plasma antibodies, plasmablasts and memory B cells Open
Introduction COVID-19 vaccines are highly effective in inducing protective immunity. While the serum antibody response to COVID-19 vaccination has been studied in depth, our knowledge of the underlying plasmablast and memory B cell (Bmem) …

Splenic rupture and fungal endocarditis in a pediatric patient with invasive fusariosis after allogeneic hematopoietic stem cell transplantation for aplastic anemia: A case report Open
Background Invasive mold infections are a well-known and life-threatening condition after allogeneic hematopoietic stem cell transplantation (HSCT). While Aspergillus species are recognized as predominant pathogens, Fusarium species should…

Predictors of post-stroke delirium incidence and duration: Results of a prospective observational study using high-frequency delirium screening Open
Background: Post-stroke delirium (PSD) is a modifiable predictor for worse outcome in stroke. Knowledge of its risk factors would facilitate clinical management of affected patients, but recently updated national guidelines consider availa…

Frequency of positive anti-PF4/polyanion antibody tests after COVID-19 vaccination with ChAdOx1 nCoV-19 and BNT162b2 Open
Vaccination using the adenoviral vector COVID-19 vaccine ChAdOx1 nCoV-19 (AstraZeneca) has been associated with rare vaccine-induced immune thrombotic thrombocytopenia (VITT). Affected patients test strongly positive in platelet factor 4 (…

A flow cytometric assay to detect platelet-activating antibodies in VITT after ChAdOx1 nCov-19 vaccination Open
Vaccination is crucial in combatting the severe acute respiratory syndrome coronavirus 2 pandemic. The rare complication of thrombocytopenia and thrombotic complications at unusual sites after ChAdOx1 nCov-19 vaccination is caused by plate…
View article: External Validation of Five Scores to Predict Stroke-Associated Pneumonia and the Role of Selected Blood Biomarkers
External Validation of Five Scores to Predict Stroke-Associated Pneumonia and the Role of Selected Blood Biomarkers Open
Background and Purpose: Several clinical scoring systems as well as biomarkers have been proposed to predict stroke-associated pneumonia (SAP). We aimed to externally and competitively validate SAP scores and hypothesized that 5 selected b…

Stroke-induced immunodepression and dysphagia independently predict stroke-associated pneumonia – The PREDICT study Open
Stroke-associated pneumonia is a frequent complication after stroke associated with poor outcome. Dysphagia is a known risk factor for stroke-associated pneumonia but accumulating evidence suggests that stroke induces an immunodepressive s…
