Comparison of prostaglandin and mechanical cervical ripening in the setting of small for gestational age neonates.

The objective of this study is to determine whether cervical ripening with misoprostol (MP) is associated with higher rates of cesarean delivery (CD) compared with dinoprostone (DP) or Pitocin/Foley balloon (PFB) in infants found to be small for gestational age (SGA). Single center institution based cohort study of all inductions between 2008 and 2012 where birth weight was found to be as SGA (< 10th percentile). Maternal demographic, obstetric, and labor characteristics were compared between SGA births where cervical ripening with MP, DP, or PFB was used as the primary agent.

Damage-Associated Molecular Pattern and Fetal Membrane Vascular Injury and Collagen Disorganization in Lipopolysaccharide-Induced Intra-amniotic Inflammation in Fetal Sheep.

Unlabelled: To understand the changes in the structural integrity of fetal membranes during intrauterine inflammation, we evaluated the time course of expression and localization of damage-associated molecular patterns (DAMPs) and injury/remodeling in collagen and vascular smooth muscle. Time-mated ewes received intra-amniotic (IA) saline or IA lipopolysaccharide (LPS) for 5 hours to 15 days prior to a preterm delivery at 125 ± 2 days (n = 5-7 animals/group). The DAMP high mobility group box 1 (HMGB1) protein assessed by Western blot was induced within 24 hours after IA LPS in the fetal membranes, and HMGB1 expression was localized to amnion epithelium, chorion vascular endothelium, and infiltrating inflammatory cells by immunohistology.
