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.

Small airways disease (SAD) is a key component of COPD and is a main contributing factor to lung function decline. ⋯ Increased Sacin may be a consequence of previous exacerbations or may highlight a group of patients prone to exacerbations. Measures of SAD were associated strongly with neutrophilic inflammation in the small airways of FE patients, supporting the hypothesis that frequent exacerbations are associated with SAD related to increased cellular inflammation.

A 54-year-old man sought treatment at the ED for a productive cough with green phlegm of approximately 6 months' duration that was accompanied by a 10-pound weight loss, night sweats, and occasional subjective fevers. He had made several prior visits to the ED for the cough and was hospitalized 4 months earlier for similar symptoms, at which time he underwent a bronchoscopy with BAL and was discharged with antibiotics for presumed pneumonia. ⋯ The patient had a past medical history of grade III follicular lymphoma for which he completed six cycles of bendamustine 4 years before presentation and had been in remission since. He was a never smoker, had a recent travel history to the Dominican Republic 8 months before admission, and had no recent sick contacts.

Case Reports
Laryngeal Injury Due to Amikacin Inhalation for Refractory Mycobacterium avium Complex Infection.
Inhaled antibiotics have long been used for chronic lung infections, especially in patients with cystic fibrosis and increasingly for non-cystic fibrosis bronchiectasis. Amikacin liposome inhalation suspension (ALIS) has emerged as a promising treatment for Mycobacterium avium complex infection refractory to oral antibiotics. ⋯ This is the first report directly describing vocal fold injury due to such therapy. Given the high frequency of dysphonia reported with ALIS, this case highlights the potential severity of laryngeal toxicity, the importance of coordination of care for patients receiving inhaled antibiotics for chronic pulmonary disease, and the need for better insight into mechanisms of toxicity.

Despite numerous advances in the understanding of the pathophysiology, progression, and management of acute respiratory failure (ARF) and ARDS, limited contemporary data are available on the mortality burden of ARF and ARDS in the United States. ⋯ The ARF-related mortality increased at approximately 3.4% annually, and ARDS-related mortality showed a lack of decline in the last 5 years. These data contextualize important health information to guide priorities for research, clinical care, and policy, especially during the coronavirus disease 2019 pandemic in the United States.
