A central tenet of caring for patients with ARDS is to treat the underlying cause, be it sepsis, pneumonia, or removal of an offending toxin. Identifying the risk factor for ARDS has even been proposed as essential to diagnosing ARDS. ⋯ In this review, we consider the historic role of pathology in establishing a diagnosis of ARDS and the published experience of surgical and transbronchial lung biopsy in patients with ARDS. We reflect on which pathologic diagnoses influence treatment and suggest a patient-centric approach to weigh the risks and benefits of a lung biopsy for critically ill patients who may have ARDS.

It is unclear whether recent advances in pulmonary arterial hypertension therapy can be safely applied to sarcoidosis-associated pulmonary hypertension (SAPH). Evidence for prostacyclin (PG) therapy in SAPH is limited. ⋯ Many patients with severe SAPH showed significant hemodynamic and clinical improvement on long-term IV or subcutaneous PG therapy and had survival outcomes similar to patients with moderate SAPH on oral vasodilator therapy.

Multicenter Study
Trends in mortality from chronic obstructive pulmonary disease among adults in the United States.
COPD imposes a large public health burden internationally and in the United States. The objective of this study was to examine trends in mortality from COPD among US adults from 1968 to 2011. ⋯ In the United States, the mortality rate from COPD has declined since 1999 in men and some age groups but appears to be still rising in women, albeit at a reduced pace.
