Childhood asthma is a prevalent condition with potential impacts on adult life. ⋯ Our 60-year follow-up study of adults with a history of severe childhood asthma revealed that nine of 10 participants still had current asthma. Persistent asthma was associated with lower lung function and higher levels of type 2 inflammatory biomarkers compared with asthma remission.

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.

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.

The 2022 European Society of Cardiology/European Respiratory Society guidelines define pulmonary hypertension (PH) as a resting mean pulmonary artery pressure (mPAP) > 20 mm Hg at right heart catheterization (RHC). Previously, patients with an mPAP between 21 and 24 mm Hg were classified in a "gray zone" of unclear clinical significance. ⋯ In this study, diffusing capacity of the lungs for carbon monoxide < 80% of the predicted value was the parameter with the highest sensitivity and NPV in detecting patients with SSc with mPAP 21 to 24 mm Hg. TAPSE/sPAP < 0.55 mm/mm Hg had the highest specificity, PPV, and accuracy and, therefore, can be a useful additional parameter to decrease the number of unnecessary RHCs.

The healthy adherer effect has gained increasing attention as a potential source of bias in observational studies examining the association of positive airway pressure (PAP) adherence with health outcomes in OSA. ⋯ This study indicated that patients who adhere to PAP therapy for OSA were more health-seeking and used less health care resources prior to device initiation than patients who were nonadherent. Until the healthy adherer effect associated with PAP adherence is better understood, caution is warranted when interpreting the association of PAP adherence with CV health outcomes and health care resource use in nonrandomized cohorts.
