Lung cancer management guidelines strive to improve outcomes. Theoretically, thorough staging promotes optimal treatment selection. We examined the association between guideline-concordant invasive mediastinal nodal staging, guideline-concordant treatment, and non-small cell lung cancer survival. ⋯ Levels of guideline-concordant staging were high, were rising, and were associated with guideline-concordant treatment selection in this multidisciplinary care cohort. Guideline-concordant staging and guideline-concordant treatment were complementary in their association with improved survival, supporting the connection between these two processes and lung cancer outcomes.

Pulmonary hypertension (PH) is a common complication of interstitial lung disease (ILD) and is associated with worse outcomes and increased mortality. Evaluation of PH is recommended in lung transplant candidates, but there are currently no standardized screening approaches. Trials have identified therapies that are effective in this setting, providing another rationale to routinely screen patients with ILD for PH. ⋯ Many patients with ILD may benefit from early evaluation of PH now that an approved therapy is available. Protocols to evaluate patients with ILD often overlap with evaluations for pulmonary hypertension-interstitial lung disease and can be used to assess the risk of PH. Because standardized approaches are lacking, this consensus statement is intended to aid physicians in the identification of patients with ILD and possible PH, and provide guidance for timely right heart catheterization.

Long-term macrolide therapy has been shown to provide benefit to those with a range of chronic respiratory conditions. However, concerns remain about the impact of macrolide exposure on the carriage and abundance of antibiotic resistance genes within the oropharynx. The potential for onward transmission of resistance from macrolide recipients to their close contacts also is poorly understood. ⋯ Although levels of erm(B) were higher in those receiving long-term macrolide therapy and evidence of gene cocarriage with close contacts was found, no evidence was found that macrolide use increased the onward transmission risk to their close contacts. This study therefore addresses concerns that long-term macrolide therapy could promote the dissemination of transmissible macrolide resistance.

Extracorporeal membrane oxygenation (ECMO) increasingly is being used to support acute respiratory failure and for bridging to lung transplantation. Bleeding and thrombosis are common complications in the acute setting, but the literature describing long-term ECMO complications is limited, and no previous reports have been made of delayed central venous strictures resulting from remote ECMO bridging. ⋯ The severe stricture and secondary thrombosis were managed with inferior vena cava angioplasty, stenting, thrombectomy, and thrombolysis, leading to clinical improvement. This case highlights the need for awareness and monitoring for long-term vascular complications in a growing population of patients who have received ECMO support.

Case Reports
Recurrent Pleuritic Chest Pain, Lobar Consolidation, and Pleural Effusion in a 50-Year-Old Woman.
A 50-year-old woman with a history of permanent atrial fibrillation (AF) treated with radiofrequency catheter ablation (RFCA) 6 months ago was admitted to the respiratory department of a tertiary hospital because of recurrent episodes of pleuritic chest pain in the preceding 5 months. The patient reported multiple visits to a regional hospital, where she was treated with broad-spectrum antibiotics after discovery of a left alveolar consolidation on chest radiograph (Fig 1), subsequently imaged with CT scan (Fig 2). On treatment failure and appearance of a left-sided pleural effusion during outpatient follow-up, the patient was re-admitted. ⋯ After emergence of left hilar lymphadenopathy (< 1 cm), a PET-CT scan was performed. The left lower inferior lobe consolidation, whose metabolic activity pattern was consistent with that of inflammation (standardized uptake value equal to 4.4) (Fig 4), as well as the left sided-pleural effusion were markedly improved compared with previous imaging 20 days after corticosteroid initiation (Fig 2). On the grounds of recalcitrant pleuritic pain and pleural effusion recurrence during corticosteroid tapering, the patient was referred to the respiratory department of our university hospital to have her condition diagnosed.
