Background: The cold ischemia time (CIT) is a period of time between harvesting an organ for transplant and its reperfusion just after implantation. CIT may have an impact on frequency of complications after lung transplant that can be treated by means of bronchoscopic intervention. The aim of the study was to investigate the correlation between CIT and frequency of bronchoscopic intervention.
Methods: The retrospective study consists of 91 patients: 22 single lung recipients (24%) and 69 double lung recipients (76%) who underwent lung transplant from March 2012 to June 2019. All statistical analyses were performed in SPSS 25.0 and R 3.5.3. The P levels less than .05 were deemed statistically significant.
Results: The average CIT in single lung transplant was 5.91 hours, and in double lung transplant it was 8.61 hours. For the 4- to 8-hour CIT the percentages were 80.95% for single lung recipients and 46.38% for double lung recipients. For CIT longer than 8 hours, the following percentages were observed: 9.53% in single lung transplant and 53.62% in double lung transplant. Each subsequent hour of CIT exponentially increases the risk of intervention 1505 times (50.05%).
Conclusions: Prolonged CIT seems to be a risk factor for airway complication, especially in the double lung recipient group.

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.

Background: Asthma is a prevalent respiratory disease, and its management remains largely unsatisfactory. Mesenchymal stem cells (MSCs) have been demonstrated to be efficacious in reducing airway inflammation in experimental allergic diseases, representing a potential alternative treatment for asthma. Migrasomes are recently identified extracellular vesicles (EVs) generated in migrating cells and facilitate intercellular communication.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Background: Donor acquired allergy (DAA) occurs when donors transfer their allergies to recipients through solid organ transplant (SOT). However, the risk of DAA in recipients of organs from allergic donors has not been systematically characterized.
Objective: We sought to synthesize the available evidence on the risk of DAA in SOT recipients.
