Multicenter StudyAssessing the potential impact of extending antenatal steroids to the late preterm period.
In 2016, guidance statements were issued by the Society for Maternal-Fetal Medicine and the American Congress of Obstetricians and Gynecologists about extending antenatal steroid use to selected late preterm singleton pregnancies. ⋯ Careful consideration of which pregnancies should receive late preterm antenatal steroids and how to identify these pregnancies is important to optimize benefits and mitigate potential risks of this intervention.

Randomized Controlled TrialImpact of evidence-based interventions on wound complications after cesarean delivery.
A number of evidence-based interventions have been proposed to reduce post-cesarean delivery wound complications. Examples of such interventions include appropriate timing of preoperative antibiotics, appropriate choice of skin antisepsis, closure of the subcutaneous layer if subcutaneous depth is ≥2 cm, and subcuticular skin closure with suture rather than staples. However, the collective impact of these measures is unclear. ⋯ Implementation of evidence-based measures significantly reduces wound complications, but the residual risk remains high, which suggests the need for additional interventions, especially in patients who undergo unscheduled cesarean deliveries, who are at risk for wound complications even after receiving current evidence-based measures.

Neonatal outcomes in fetuses with cardiac anomalies and the impact of delivery route.
Congenital fetal cardiac anomalies compromise the most common group of fetal structural anomalies. Several previous reports analyzed all types of fetal cardiac anomalies together without individualized neonatal morbidity outcomes based on cardiac defect. Mode of delivery in cases of fetal cardiac anomalies varies greatly as optimal mode of delivery in these complex cases is unknown. ⋯ Most fetal cardiac anomalies were diagnosed postnatally and associated with increased rates of neonatal morbidity. Planned cesarean delivery for prenatally diagnosed cardiac anomalies was not associated with less neonatal morbidity.

Association between gestational weight gain and perinatal outcomes in women with chronic hypertension.
Gestational weight gain above or below the 2009 National Academy of Medicine guidelines has been associated with adverse maternal and neonatal outcomes. Although it has been well established that excess gestational weight gain is associated with the development of gestational hypertension and preeclampsia, the relationship between gestational weight gain and adverse perinatal outcomes among women with pregestational (chronic) hypertension is less clear. ⋯ Women with chronic hypertension who gain less weight than National Academy of Medicine guidelines experience increased odds of small-for-gestational-age neonates, whereas excess weight gain ≥20 lb over National Academy of Medicine guidelines is associated with cesarean delivery, eclampsia, 5-minute Apgar <7, neonatal intensive care unit admission, and large-for-gestational-age neonates.

The relationship of the subtypes of preterm birth with retinopathy of prematurity.
Retinopathy of prematurity is an adverse outcome of preterm birth and is a leading cause of childhood blindness. The relationship between the subtypes of preterm birth with retinopathy of prematurity is understudied. ⋯ Type 1 or type 2 retinopathy of prematurity are adverse ocular outcomes linked with not only lower gestational age and birth weight at delivery but also with events in the intrauterine environment that trigger a preterm birth. The reduced incidence of type 1 or type 2 retinopathy of prematurity in the preterm premature rupture of the membranes group compared with other causes of preterm birth may be related to the perinatal therapies associated with preterm premature rupture of the membranes (such as corticosteroids, antibiotics, maternal-fetal surveillance), which may have an inhibitory effect on the development of retinopathy of prematurity. We suggest that the physiologic events that predispose infants to type 1 or type 2 retinopathy of prematurity begin before delivery.
