Ten pregnant women and three pregnant sheep received mannitol intravenously. The results show that during late pregnancy this substance appears in amniotic fluid, and when the fetus is alive, its concentration increases with time, reaching values which are higher than those simultaneously obtained in maternal plasma. The experiments performed in sheep show that in fetal urine the concentration of mannitol reached values 10 to 20 times higher than those found in fetal plasma. This supports the hypothesis that the fetal kidney has an important role in the transference of this type of substance from the mother to the amniotic fluid.

Introduction: The sense of smell is one of the most developed and important senses that forms the bond between the newborn and the mother and allows the newborn to reach the mother's breast. The sense of smell begins to form during intrauterine life, and the sense of smell can be a marking tool for a newborn baby, so that the baby can recognize both his mother and his immediate environment and develop his behaviour accordingly. This is necessary not only for feeding babies but also for them to feel safe and peaceful in their new environment.

Intrapartum fever is a common complication in parturients undergoing epidural analgesia (EA), significantly increasing the incidence of maternal and infant complications. This study aims to develop and validate a prediction model for intrapartum fever related to chorioamnionitis (IFTC) in parturients undergoing epidural analgesia. A total of 596 parturients with fever (axillary temperature ≥ 38℃) who received EA from January 2020 to December 2023 were included and randomly assigned to the training set (N = 417) and the validation set (N = 179) according to the ratio of 7:3.

To investigate the effects of early-onset sepsis (EOS) on retinopathy of prematurity (ROP) in extremely premature infants (EPIs) by using propensity score matching (PSM). Clinical data of 591 EPIs admitted to NICU, Senior Department of Pediatric, PLA General Hospital from May 1, 2015 to May 1, 2022 were retrospectively analyzed. They were divided into an EOS group and a non-EOS group according to whether they had confirmed EOS or not.
