Observational StudyVentilation inhomogeneity and NO and CO diffusing capacity in ex-premature school children.
Ex-premature school children show mild-to-moderate airway obstruction and decreased CO diffusing capacity. Multiple breath nitrogen washout (N2MBW) and NO diffusing capacity (DLNO) measurements may provide new insight into long-term pulmonary and vascular impairment in bronchopulmonary dysplasia (BPD). ⋯ Ex-premature school children exhibited relatively mild but significant long-term respiratory symptoms and pulmonary peripheral impairment judged by N2MBW and DLNO measurements along with well-known airway obstruction. Larger longitudinal studies are needed to assess the clinical use of these advanced methods of assessing ventilation inhomogeneity and DLNO.

Safety of performing transbronchial lung cryobiopsy on hospitalized patients with interstitial lung disease.
Transbronchial lung cryobiopsy (TBLC) has become a popular option for tissue diagnosis of interstitial lung disease (ILD), however reports vary regarding the safety of this procedure. Herein, we evaluate the safety of transbronchial cryobiopsy in hospitalized patients, comparing adverse events to outpatient procedures. ⋯ Practitioners should recognize that while cryobiopsies are a high-yield, safe, and cost-effective alternative to surgical lung biopsy, not all procedures carry the same risk profiles. Hospitalized patients may have a greater propensity for pneumothorax, persistent air leak, transfer to the ICU, and 30-day mortality.
