Palas D, et al. - This work was planned to assess the efficacy of ACS therapy on short-term neonatal outcomes in preterm twins and further document the influence of the ACS-to-delivery interval. In preterm twins, researchers observed an improvement of severe neurological outcome with a single complete course of antenatal corticosteroids. However, reduction in in-hospital mortality was observed only when the ACS-to-delivery interval was ≤7 days.
