TNFRSF1B Signaling Blockade Protects Airway Epithelial Cells from Oxidative Stress.

Progressive respiratory airway destruction due to unresolved inflammation induced by periodic infectious exacerbation episodes is a hallmark of cystic fibrosis (CF) lung pathology. To clear bacteria, neutrophils release high amounts of reactive oxygen species (ROS), which inflict collateral damage to the neighboring epithelial cells causing oxidative stress. A former genome-wide small interfering RNA (siRNA) screening in CF submucosal gland cells, instrumental for mucociliary clearance, proposed tumor necrosis factor receptor superfamily member 1B (; ) as a potential hit involved in oxidative stress susceptibility.

Impact of Coronavirus-19 Pandemic and Lockdown on Admissions for Ischemic Heart Disease.

Background: In early 2020, the SARS-CoV-2 pandemic caused an unprecedented overload for the health service. A decrease in admissions for Acute Coronary Syndrome (ACS) was reported during lockdown, although many aspects remain to be clarified. The main objective of this study was to evaluate the impact of the pandemic and of lockdown itself in this area.
