Pulmonary fibrosis (PF) is a lethal pathological change of fibrotic interstitial lung diseases (ILDs) with abundant fibroblasts proliferation after severely or continually alveolar epithelial cells (AECs) injury. Barely therapies are helpful for PF. Here we use bleomycin intratracheally injection to model PF with or without human umbilical cord-mesenchymal stem cells (hUC-MSCs) and/or nintedanib intervention.

Introduction: The factors influencing meconium aspiration syndrome (MAS) severity remain poorly understood. In a piglet model of MAS, we hypothesized the respiratory microbiome would reflect the bacterial signature of meconium with short-chain fatty acid (SCFA) accumulation as a byproduct of bacterial fermentation.
Methods: Cesarean section at approximately 115-day term was performed on two sows.
Implications for the diagnosis of aspiration and aspergillosis in critically ill patients with detection of galactomannan in broncho-alveolar lavage fluids.

Invasive infections with Aspergillus fumigatus in ICU patients are linked to high morbidity and mortality. Diagnosing invasive pulmonary aspergillosis (IPA) in non-immunosuppressed patients is difficult, as Aspergillus antigen (galactomannan [GM]) may have other causes. This retrospective study analyzed 160 ICU surgical patients with positive GM in broncho-alveolar lavage fluid (BALF), classifying them based on AspICU criteria for suspected IPA (pIPA) or aspiration.

ZBP1-driven cell death in severe influenza.

Center for Immunology, Fox Chase Cancer Center, Philadelphia, PA, USA. Electronic address:
Influenza A virus (IAV) infections can cause life-threatening illness in humans. The severity of disease is directly linked to virus replication in the alveoli of the lower respiratory tract. In particular, the lytic death of infected alveolar epithelial cells (AECs) is a major driver of influenza severity.
