Journal ArticleDOI
Endobronchial Valves Therapy for Advanced Emphysema: A Meta-Analysis of Randomized Trials.
TL;DR: BLVR using EBV shows short-term improvement in lung function and quality of life, but with increased risk of minor hemoptysis, pneumothorax, and valve migration.

Journal ArticleDOI
COPD: To Be or Not to Be, That is the Question.
TL;DR: The many faces of COPD are discussed from an epidemiological, pathobiological, and clinical standpoint and it is argued that airflow limitation encompasses a number of manifestations that are too diverse to be still clustered under the same diagnostic label.
