Observational Study
Abdominal Muscle Use during Spontaneous Breathing and Cough in Mechanically Ventilated Patients: a bi-center ultrasound study.
Ultrasound may be useful to assess the structure, activity, and function of the abdominal muscles in patients who are mechanically ventilated. ⋯ ClinicalTrials.gov; No.: NCT03567564; URL: www.clinicaltrials.gov.

Comparative Study
Comparison of First Nations and non-First Nations children's profiles with bronchiectasis over two five-year periods from the Northern Territory, Australia.
Although the burden of bronchiectasis is recognized globally, pediatric data are limited, particularly on trends over the years. Also, no published data exists regarding whether vitamin D deficiency or insufficiency and human T-cell lymphotropic virus type 1 (HTLV-1) infection, both found to be related to severe bronchiectasis in First Nations adults, also are important in children with bronchiectasis. ⋯ Bronchiectasis remains high particularly among First Nations children. Important changes in their profiles that arguably reflect improvements were present, but overall, the profiles remained similar. Although vitamin D deficiency was uncommon, its role in children with bronchiectasis requires further evaluation. HTLV-1 infection was nonexistent and is unlikely to play any role in First Nations children with bronchiectasis.

Observational Study
Safety and Performance of Transbronchial Cryobiopsy for Parenchymal Lung Lesions.
Despite advances in technology, the bronchoscopic diagnosis of parenchymal pulmonary lesions (PPLs) remains difficult to achieve. Transbronchial lung cryobiopsy (TLCB) offers the potential for larger samples with improved diagnostic yield; however, a paucity of data exists describing its safety and usefulness for the diagnosis of PPL. ⋯ TLCB showed an acceptable safety profile and diagnostic yield for the evaluation of PPL in this large retrospective cohort. Prospective clinical trials are underway to validate these findings further.
