Chest
-
An 85-year-old Japanese man, who was taking aspirin and edoxaban for previous myocardial infarction and atrial fibrillation, came to our hospital with a chief complaint of dyspnea for 3 weeks. Chest radiography showed a massive left pleural effusion (Fig 1A). ⋯ However, he had neither coagulation disorder nor thrombocytopenia, and the pleural effusion was negative for atypical cells. These findings suggested that the antithrombotic and anticoagulant medications might have induced the hemothorax.

Observational Study
Alternative gene expression by TOLLIP variant is associated with lung function in chronic hypersensitivity pneumonitis.
Chronic hypersensitivity pneumonitis (CHP) is a heterogeneous fibrotic interstitial pneumonia resulting from the immune response of susceptible individuals to inhaled antigens. Genetic predispositions have been suggested in CHP; however, the link between susceptibility genes and fibrotic progression has not been elucidated fully. Recent data suggest that variants in Toll-interacting protein gene (TOLLIP) are associated with lung diseases. ⋯ The functional changes by TOLLIP variant were associated with rapid FVC decline through dysregulated Smad/transforming growth factor β and NF-κB signaling in CHP.

Comparative Study
Rationing With Respect to Age During a Pandemic: A Comparative Analysis of State Pandemic Preparedness Plans.
Faced with possible shortages due to COVID-19, many states updated or rapidly developed crisis standards of care (CSCs) and other pandemic preparedness plans (PPPs) for rationing resources, particularly ventilators. ⋯ Guidance with respect to rationing by age and/or life-years varied widely. More than one-half of PPPs, many following a few common models, included age/life-years as an explicit rationing criterion; the majority of these made it a primary consideration. Terminology was often vague, and many plans evolved in response to pushback. These findings have ethical implications for the care of older adults and other vulnerable populations during a pandemic.

Case Reports
An Acute Exacerbation of Idiopathic Pulmonary Fibrosis After BNT162b2 mRNA COVID-19 Vaccination: A Case Report.
Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease characterized by progressive scar tissue formation. An acute exacerbation of IPF (AE-IPF) is a clinically significant respiratory decompensation that accounts for a significant proportion of IPF-related morbidity and mortality. ⋯ In this novel case report, we describe a potential association between AE-IPF and BNT162b2 mRNA COVID-19 vaccination that was successfully treated with a short course of glucocorticoids. While our aim is to raise awareness for this yet-to-be-described adverse event, immunization against vaccine-preventable disease remains widely recommended in vulnerable patients with chronic lung disease such as IPF.
