Multicenter Study
Achieving Molecular profiling in Pleural Biopsies: a multicentre, retrospective cohort study.
Pleural biopsy findings offer greater diagnostic sensitivity in malignant pleural effusions compared with pleural fluid. The adequacy of pleural biopsy techniques in achieving molecular marker status has not been studied, and such information (termed "actionable" histology) is critical in providing a rational, efficient, and evidence-based approach to diagnostic investigation. ⋯ Although previous studies have shown comparable overall diagnostic yields, in the modern era of targeted therapies, this study found that LAT offers far superior results to image-guided techniques at achieving molecular profiling and remains the optimal diagnostic tool.

Patients with bronchopulmonary dysplasia (BPD) have poor respiratory trajectories and are at increased risk of lung function decline with age. Lung transplant (LTx) is a possible treatment option for this growing patient population, but little has been published on LTx in this patient group. ⋯ LTx for BPD has increased over the last 20 years. Patients with BPD have similar post-LTx outcomes compared with those of other patient populations in the modern era. Thus, LTx could be considered for patients with BPD experiencing progressive respiratory deterioration.

A critical need exists to develop remission-inducing therapies for lymphangioleiomyomatosis. ⋯ The addition of resveratrol was safe and well tolerated in patients with lymphangioleiomyomatosis taking sirolimus and was associated with modest improvement in HRQOL. Larger controlled trials of this combination might be warranted to assess definitively the usefulness of resveratrol as an additive therapy in lymphangioleiomyomatosis.

Pulmonary arteriovenous malformations (PAVMs) are rare and most often identified in patients with hereditary hemorrhagic telangiectasia (HHT). We describe a patient with severe hypoxemia and orthodeoxia with imaging findings consistent with PAVMs. Resected lung pathologic findings confirmed the presence of numerous microscopic vascular abnormalities within the right lower lobe that was consistent with diffuse pulmonary arteriovenous shunts. ⋯ Cys123∗). Pathogenic variants in BMPR2 are a well-known cause of hereditary PAH; there have been several reports to date of patients with PAVMs and PAH. However, this is the first patient to be reported with a pathogenic variant in BMPR2 to have PAVMs in isolation.
