The major risk factors for BPD are prematurity, mechanical ventilation, exposure to noxious insults such as oxygen, infections. New research data both in basic science and clinical studies have shed light on the pathogenesis, and possible new treatment or management strategies for the future. In the proposed issue of the Clinics in Perinatology, we would like to comprehensively cover BPD both from a basic science and clinical perspective. Our attempt is to balance new information along with classic topics. The proposed authors for the issue are recognized experts in the topic area/s. We hope that the issue will be of interest to a broad array of readership.
