In recent years, the role of oxidative stress as physiopathological factor for several diseases has been elucidated and many studies have investigated this topic in relation to pregnancy disorders and preterm infants’ complications. These include preterm delivery, preeclampsia, intrauterine growth restriction, chorioamnionitis, bronchopulmonary dysplasia, retinopathy of prematurity, and necrotizing enterocolitis, respectively. These studies demonstrated that oxidative stress can highly contribute to the development of these pathologies mainly inducing tissue inflammation.

Thus, the aim of this special issue is to collect papers on effects of oxidative stress from the conception to the delivery for giving a comprehensive picture of this issue in perinatology. Therefore, research studies or review articles which describe the current state of the art are welcome with particular attention.

Potential topics include but are not limited to the following:

• Oxidative stress and placental pathologies
• Oxidative stress and preeclampsia
• Oxidative stress and intrauterine growth restriction
• Oxidative stress and chorioamnionitis
• Oxidative stress and preterm delivery
• Oxidative stress and congenital malformation
• Oxidative stress and genetic syndromes
• Oxidative stress and bronchopulmonary dysplasia
• Oxidative stress and retinopathy of prematurity
• Oxidative stress and necrotizing enterocolitis
• Oxidative stress and brain damage in preterm infants
• Oxidative stress and neonatal hypoxic-ischemic encephalopathy
• Oxidative stress and neonatal hyperbilirubinemia
