Neonatology Questions and Controversies: The Newborn Lung

Perinatal nutrition and the lung

Key points Lung development is influenced by both prenatal and postnatal nutrient quality and quantity. The wide spectrum of maternal and preterm infant nutritional states has differing impacts on the trajectory of fetal-infant lung development. Specific nutrient supplements given during…

Long-term pulmonary outcome of preterm infants

Key points Preterm infants are vulnerable to adverse long-term sequelae including pulmonary outcomes. Respiratory morbidities, including hospitalizations for respiratory infections, asthma, and wheezing illnesses, are higher in those born preterm compared with term. These risks decrease as the children get…

Cell-based therapy for neonatal lung diseases

Key points The postnatal lung contains populations of stem cells that reconstitute the lung following injury. Prematurity and its antecedent factors alter endogenous stem cells leading to dysfunctional lung repair. Preterm infants who develop bronchopulmonary dysplasia (BPD) exhibit decreased and/or…
