Institutional-level disparities in non-small cell lung cancer (NSCLC) survival may be driven by reversible differences in care-delivery processes. We quantified the impact of differences in readily identifiable quality metrics on long-term survival disparities in resected NSCLC. ⋯ Targeting six readily identified poor-quality markers narrowed, but did not eliminate, institutional survival disparities. The greatest impact was in community programs. Residual factors driving persistent institution-level long-term NSCLC survival disparities must be characterized to eliminate them.

Aberrations in the coagulation system have been implicated in the pathogenesis of interstitial lung disease (ILD). Anticoagulants have been proposed as a potential therapy in ILD; however, a randomized controlled trial examining warfarin as a treatment for IPF was terminated early due to increased death rates. This has led some to speculate that warfarin specifically may be harmful in ILD, and use of direct oral anticoagulants (DOACs) could result in superior outcomes. ⋯ The need for anticoagulation is associated with an increased risk for death or transplant in patients with ILD, in both the IPF and non-IPF population. Further research is required to determine if warfarin and DOACs present varying safety profiles in patients with ILD.

The impact of ECG presentations of acute myocardial infarction (AMI) in cardiogenic shock is unknown. ⋯ In patients with cardiogenic shock, NSTEMI and LBBBMI presentations reflect higher-risk profiles than STEMI presentations, but are not independent risk factors of mortality. ECG presentations did not modify the treatment effect, supporting culprit-lesion-only percutaneous coronary intervention as the preferred strategy across the AMI spectrum.

Case Reports
Benralizumab for Prednisone-Dependent Eosinophilic Asthma Associated With Novel STAT3 Loss of Function Mutation.
Some severe asthmatic patients experience frequent bacterial respiratory tract infections, which contribute significantly to their disease burden, and often are attributed to their use of systemic corticosteroids and comorbid bronchiectasis. We report a case of a 58-year-old woman who had prednisone-dependent asthma and exacerbations with intense mixed eosinophilic and neutrophilic bronchitis. Autosomal dominant hyper-IgE syndrome, which is a primary immunodeficiency characterized by elevated IgE, eosinophilia, and recurrent infections, caused by a novel pathogenic mutation in STAT3 was identified as the cause of her airway disease. We believe that this is the first report of the demonstration of an IL-5 driven eosinophilia that is associated with a STAT3 mutation that was treated successfully with an anti-IL5 biological.
