Meta Analysis
Reduced COPD exacerbation risk correlates with improved FEV1: A meta-regression analysis.
The mechanism by which various classes of medication reduce COPD exacerbation risk remains unknown. We hypothesized a correlation between reduced exacerbation risk and improvement in airway patency as measured according to FEV1. ⋯ A significant correlation between increased FEV1 and lower COPD exacerbation risk suggests that airway patency is an important mechanism responsible for this effect.

Endoscopic lung volume reduction has emerged over the past several years as a promising technique to improve the respiratory functional status of patients with advanced emphysema. Nevertheless, the procedure may be associated with various complications; among them, the development of bronchiectasis related to the coils has not yet been described. We report the case of a patient with emphysema who developed localized bronchiectasis at the site of coil insertion several months after lung volume reduction coil treatment.

Review Meta Analysis
Video Laryngoscopy for Endotracheal Intubation of Critically Ill Adults: A Systemic Review and Meta-analysis.
Endotracheal intubation (EI) in ICU patients is associated with an increased risk of life-threatening adverse events due to unstable conditions, rapid deterioration, limited preparation time, and variability in the expertise of operators. The goal of this study was to compare the effect of video laryngoscopy (VL) and direct laryngoscopy (DL) in ICU patients requiring EI. ⋯ The VL technique did not increase the first-attempt success rate during EI in ICU patients compared with DL. These findings do not support routine use of VL in ICU patients.
