Respiratory Research Analysis
February’s respiratory research featured practice-changing and mechanistic advances. A large cluster RCT showed that a digitally enabled stewardship program sharply reduced antibiotic prescribing for ARIs without compromising safety. A mechanistic Immunity study uncovered a lung–heart axis in influenza linking infected CCR2+ myeloid cells to cardiomyocyte IFNAR1-dependent injury, suggesting organ-targeted protection. A pragmatic phase 3 RCT found earlier-in-the-day anti–PD-1-based immunochemothe
