COPD and bronchiectasis frequently coexist, which creates an emerging phenotype with a worse prognosis. However, the impact of bronchiectasis on the natural history of COPD has not been fully evaluated and is still controversial. This meta-analysis was performed to clarify the associations of the presence of bronchiectasis with the prognosis and quality of life of patients with COPD. ⋯ This meta-analysis confirmed the significant associations of the presence of bronchiectasis with the natural history, disease course, and outcomes in COPD. The COPD-bronchiectasis phenotype had adverse effects on subjects' health condition and prognosis.

Multicenter Study
Respiratory Therapist Intubation Practice in Pediatric ICUs: A Multicenter Registry Study.
Tracheal intubation by respiratory therapists (RTs) is a well-established practice that has been described primarily in adult and neonatal patients. However, minimal data exist regarding RTs' intubation performance in pediatric ICUs. The purpose of this study was to describe the current landscape of intubations performed by RTs in pediatric ICUs. ⋯ RTs infrequently intubate in pediatric ICUs, with success rates similar to other providers but higher adverse event rates. RTs were more likely to use video laryngoscopy than other providers. RTs' intubation participation, success, and adverse event rates varied greatly across pediatric ICUs.

Comparative Study
Comparison of Vibrating Mesh, Jet, and Breath-Enhanced Nebulizers During Mechanical Ventilation.
This study compared 3 nebulizer technologies for inter- and intradevice reproducibility, humidification, and fill volume sensitivity during mechanical ventilation: a breath-enhanced jet nebulizer, a vibrating mesh nebulizer, and a jet nebulizer. The breath-enhanced jet nebulizer featured a new design located on the wet side of the humidifier to reduce aerosol loss and potential humidifier contamination. The vibrating mesh nebulizer and the jet nebulizer were placed on the dry side. ⋯ Nebulization with the breath-enhanced jet nebulizer was less sensitive to humidification than the jet nebulizer. Delivery via the vibrating mesh nebulizer was not predictable, with random failure to empty (55% experimental runs). All devices delivered similar particle distributions. Wet-side aerosol delivery avoids humidifier contamination, and breath-enhanced technology can ensure better control of drug delivery.

Inhaled pulmonary vasodilators are a powerful tool in the arsenal of therapies designed to treat pulmonary hypertension in pediatrics. Yet only 1 inhaled vasodilator, inhaled nitric oxide (INO), has been approved by the Food and Drug Administration for use in neonates > 34 weeks gestational age with persistent pulmonary hypertension of the newborn. ⋯ Advancements in technology have led to the creation of nitric oxide generation devices that do not require tanks. This review evaluates the current evidence regarding the use of inhaled vasodilators and INO delivery devices in the neonatal and pediatric intensive care population.
