Patients with COVID-19 report severe respiratory symptoms consistent with ARDS. The clinical presentation of ARDS in COVID-19 is often atypical, as patients with COVID-19 exhibit a disproportionate hypoxemia compared with relatively preserved lung mechanics. ⋯ We present our experience with exogenous surfactant treatment in a patient with COVID-19 experiencing COVID-19-related ARDS. The patient responded with improved oxygenation, and we believe surfactant was the catalyst for the successful extubation and clinical improvement of the patient.

Inhalational exposures are increasingly recognized as contributing factors in interstitial lung disease (ILD). However, the characteristics of both exposures and exposed patients are not well understood. We hypothesized that domestic and occupational inhalational exposures would be common and associated with differences in demographics, clinical characteristics, and transplant-free survival in patients with all forms of ILD. ⋯ A standardized interview revealed most patients across all types of ILD had potentially relevant inhalational exposures. Exposures were markedly different based on demographics and were associated with worse transplant-free survival, but this survival difference was not significant after multivariable adjustment. Identification and avoidance of exposures represent actionable targets in ILD management.

Despite the frequency and cost of hospitalizations for acute respiratory failure (ARF), the literature regarding the impact of hospital safety net burden on outcomes of these hospitalizations is sparse. ⋯ After accounting for differences between patient cohorts, high safety net burden was associated independently with inferior clinical outcomes and increased costs after ARF hospitalizations. These findings emphasize the need for health care reform to ameliorate disparities within these safety net centers, which treat our most vulnerable populations.

Early initiation of pulmonary arterial hypertension (PAH) therapies is associated with improved long-term outcomes, yet data on the early use of prostacyclin pathway agents are limited. In these post hoc analyses of the Prostacyclin (PGI2) Receptor Agonist In Pulmonary Arterial Hypertension (GRIPHON) study, the largest randomized controlled trial for PAH to date, the prognostic value of time from diagnosis and its impact on treatment response were examined. ⋯ In the GRIPHON study, newly diagnosed PAH patients had a worse prognosis than patients with a longer time from diagnosis. The benefit of selexipag treatment on disease progression was more pronounced in patients treated earlier than in patients treated later.

A 44-year-old man with hyperthyroidism and no smoking history presented to his internist with 5 months of intermittent cough and hemoptysis. The patient's family history was remarkable only for non-Hodgkin's lymphoma in his father. ⋯ A chest radiograph showed bilateral nodular opacities with a left lower lobar consolidative opacity (Fig 1A, 1B); the patient underwent CT scanning of the chest, which showed areas of nodular infiltration in the lower lobes with tree-in-bud-like opacities. He was referred to a pulmonologist.
