ARDS is a heterogeneous condition with two subphenotypes identified by different methodologies. Our group similarly identified two ARDS subphenotypes using nine routinely available clinical variables. However, whether these are associated with differential response to treatment has yet to be explored. ⋯ We found evidence of differential response to PEEP strategies across two ARDS subphenotypes, suggesting possible harm with a higher PEEP strategy in one subphenotype. These observations may assist with predictive enrichment in future clinical trials.

A 78-year-old man with a history of GI stromal tumor (GIST) in the stomach with metastasis to the liver presented with progressive shortness of breath, dry cough, and subjective fever that started 1 week after radioembolization of liver metastatic lesions. His initial diagnosis of GIST was 10 years before, for which he underwent surgical resection; however, more recently he was noted to have hepatic lesions biopsy-proven to be metastatic GIST lesions. ⋯ His medical history was otherwise notable for coronary artery disease post coronary artery bypass graft in 2002, heart failure with reduced ejection fraction, and atrioventricular block after pacemaker placement. After the diagnosis of liver metastasis, he began treatment with imatinib 6 months earlier and consequently received radioembolization with yttrium-90 (Y-90) microspheres.

Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality worldwide. Limited evidence is available on the most effective diagnostic approaches, management strategies, and long-term outcomes for CAP in patients who have undergone solid organ transplantation. ⋯ This comprehensive analysis highlights the high morbidity associated with CAP after transplantation. It also emphasizes the need for prospective multicenter studies to guide evidence-based practices and improve outcomes for these vulnerable patients.
