Background: Whether nodular lesions have specific risk-factors or influence outcomes in lung transplant recipients with invasive aspergillosis, is not fully known.
Methods: The study population consisted of 64 consecutive lung transplant recipients with proven or probable invasive aspergillosis. Nodules, with or without halo/air crescent-sign were considered nodular presentations. Outcomes assessed were response rate (successful versus unsuccessful outcome) and all-cause mortality at 12 weeks.
Results: Overall, 34 patients had nodular and 30 had non-nodular lesions. Presence of nodular lesions was less likely to be associated with renal failure at baseline (adjusted OR 0.21, 95% CI, 0.04-0.97, p = 0.047), CMV infection (adjusted OR 0.18, 95% CI 0.04-0.75, p = 0.019) and receipt of antifungal prophylaxis (adjusted OR 0.22, 95% CI, 0.06-0.88, p = 0.032). Successful outcome and mortality rates in the study patients were 64.0% (41/64) and 25.0% (16/64), respectively. Nodular aspergillosis was associated with significantly higher successful outcome (adjusted OR 3.35, 95% CI, 1.06-10.54, p = 0.039) and lower mortality at 12 weeks (adjusted OR 0.20, 0.05-0.78, p = 0.021).
Conclusions: Lung transplant recipients with nodular lesions due to invasive aspergillosis had better outcomes than those without such lesions.

New onset of protein-losing enteropathy in a patient with Fontan circulation after COVID-19 vaccination: dread the cure or the disease?

We present the case of a 31-year-old female with Fontan circulation who developed signs of protein-losing enteropathy 10 days after second COVID-19 vaccination. After standard investigations for identification of potential triggers for protein-losing enteropathy, we concluded that coronavirus disease 2019 (COVID-19) booster vaccination could have been the most probable underlying trigger. Prompt investigation of new symptoms post-vaccination in high-risk patients is necessary.

Objective: A series of webinars covering widespread knowledge on paediatric cardiology and cardiac surgery topics was initiated by Association for European Paediatric and Congenital Cardiology, serving towards preparation for the Association for European Paediatric and Congenital Cardiology certification in paediatric and congenital cardiology. This study investigated the impact of webinars as educational tools for junior paediatric cardiologists in the post-COVID-19 pandemic era.

Exemplified by successful use in COVID-19 vaccination, delivery of modified mRNA encapsulated in lipid nanoparticles provides a framework for treating various genetic and acquired disorders. However, lipid nanoparticles that can deliver mRNA into specific lung cell types have not yet been established. Here, we sought whether poly(®-amino ester)s (PBAE) or PEGylated PBAE (PBAE-PEG) in combination with 4A3-SC8/DOPE/cholesterol/DOTAP lipid nanoparticles (LNP) could deliver mRNA into different types of lung cells in vivo.

Introduction: Immune checkpoint inhibitors (ICI) have improved the therapeutic arsenal in outpatient oncology care; however, data on necessity of hospitalizations associated with immune-related adverse events (irAEs) are scarce. Here, we characterized hospitalizations of patients undergoing ICI, from the prospective cohort study of the immune cooperative oncology group (ICOG) Hannover.
Methods: Between 12/2019 and 06/2022, 237 patients were included.
