Randomized Controlled Trial Comparative Study
Effect of Drug Targeting Nebulization on Lung Deposition: A Randomized Crossover Scintigraphic Comparison Between Central and Peripheral Delivery.
Recent technological advances in nebulization permit researchers to target specific parts of the lungs by modifying delivery method. The aim of this study was to compare the central and peripheral targeted modalities of administration. ⋯ This study shows for the first time that choosing 2 different specific drug targeting nebulization modes does not influence the amount of drug delivered into the lung in healthy male subjects. Moreover, the modes do not modify the site of deposition under the conditions of our study.

Randomized Controlled Trial Multicenter Study
Identifying Cancer Patients With Acute Respiratory Failure at High Risk for Intubation and Mechanical Ventilation.
We sought to identify risk factors for mechanical ventilation in patients with malignancies and acute respiratory failure (ARF). ⋯ In cancer patients with ARF, hypoxemia, extent of pulmonary infiltration on chest x-ray, or hemodynamic dysfunction are risk factors for invasive mechanical ventilation. Mortality was not significantly different between NIV failure and first-line intubation.
