Background: Small-for-gestational age (SGA) infants are at significantly increased risk of perinatal complications, but the risk of recurrent SGA is not well known, particularly as there are many demographic and obstetric factors that interact and modify this risk. We investigated the relationship between previous SGA births and the risk of recurrence at term in a large Australian cohort.

Objective(s): We aimed to identify key demographic and obstetric variables that influence the risk of recurrence of an SGA infant at term. Read More

Emerging literature has shown that women with sleep-disordered breathing (SDB) have increased risk for gestational hypertension/preeclampsia and gestational diabetes. Case reports suggest an association between maternal apnea and fetal heart rate deceleration but data are lacking on how maternal sleep impacts fetal health. Since decelerations may be associated with adverse outcomes, we sought to determine whether fetal heart rate decelerations were associated with SDB. Read More

Preeclampsia, defined as new-onset hypertension accompanied by proteinuria occurring at 20 weeks of gestation or later, is a leading cause of perinatal morbidity and mortality worldwide. The pathophysiology of this major multi-systemic syndrome includes defective deep placentation, oxidative stress, endothelial dysfunction, the presence of an anti-angiogenic state, and intravascular inflammation, among others. In this review, we provide a comprehensive overview of the cellular immune responses involved in the pathogenesis of preeclampsia. Read More

Background: In accordance with the guidelines for the expectant management of women exposed to previable preterm premature rupture of membrane, we compared neonatal outcomes according to the latent period from membrane rupture to delivery among extremely preterm infants exposed to maternal preterm premature rupture of membrane using the Korean Neonatal Network database.

Methods: Of the 3,305 extremely preterm infants born at 23-27 weeks' gestation between 2014 and 2017 who were registered in the Korean Neonatal Network, 1,464 infants were born to pregnant women who were exposed to preterm premature rupture of membrane. The short latency group was defined as infants born with a latent period between membrane rupture and delivery < 7 days (n = 450), whereas the prolonged latency group was defined as infants born with a latent period of ≥ 7 days (n = 434).

Antiphospholipid syndrome (APS) increases the risk of obstetric complications, but risk factors for pregnancy morbidity in women with APS remain incompletely characterized. This retrospective study included pregnant women with APS and a control group without APS admitted to Peking University People's Hospital between January 2013 and September 2019. Clinical data were extracted from medical records. Read More
