Pregnancy creates a unique situation in which both vasculogenesis and extensive angiogenesis are required for successful fetal and placental development. Recently, the soluble form of vascular endothelial growth factor (VEGF) receptor-1 (sVEGFR-1), an antagonist to VEGF and placental growth factor (PlGF) (two important angiogenic factors), has been implicated in the pathophysiology of preeclampsia and small for gestational age (SGA) without preeclampsia. There is, however, a paucity of information concerning plasma sVEGFR-1 concentrations in other obstetrical disorders. The purpose of this study was to determine plasma sVEGFR-1 concentrations in normal pregnancy, term gestation in labor, and in patients with pregnancy complications including spontaneous preterm labor, preterm premature rupture of the membranes (PROM), fetal death, and acute pyelonephritis. ⋯ Plasma sVEGFR-1 concentration is increased in a subset of patients with fetal death, but does not change in term and preterm parturition, rupture of fetal membranes, or acute pyelonephritis.

Mid- and long-term outcome of extremely low birth weight (ELBW) infants: an analysis of prognostic factors.
To evaluate morbidity and long-term neurological outcome in a group of extremely low birth weight infants (ELBW; <1000 g) and to correlate the neurological outcome in a small group of intrauterine growth retarded (IUGR) infants with Doppler indices in the umbilical artery. ⋯ This study, confirms that an extremely low birth weight implies a high risk of perinatal mortality and neonatal morbidity, but that the most significant variable that can be correlated to the long-term neurological outcome is the gestational age.

The Alabama Preterm Birth Study: diffuse decidual leukocytoclastic necrosis of the decidua basalis, a placental lesion associated with preeclampsia, indicated preterm birth and decreased fetal growth.
Laminar necrosis, a band-like distribution of coagulative necrosis, has been reported at the choriodecidual interface of the free membranes of placentas of women with various adverse neonatal outcomes. Our goal in this study was to evaluate the frequency of an equivalent feature in the decidua basalis, diffuse decidual leukocytoclastic necrosis (DDLN), a diffuse coagulative necrosis admixed with karyorrhectic debris, in preterm births <32 weeks, and to determine its association with various obstetric conditions, markers of placental inflammation, and newborn outcome. ⋯ DDLN of the decidua basalis is relatively common in placentas of 23-32 week newborns, and, when present, is inversely associated with inflammatory maternal and newborn conditions and positively associated with preeclampsia, indicated preterm birth, and lower birth weight. The positive correlation of DDLN with obstetrical and neonatal conditions associated with underperfusion of the placental bed, suggests that DDLN may be a marker of vascular compromise.

Shoulder dystocia without versus with brachial plexus injury: a case-control study.
To delineate factors that differentiate shoulder dystocia with and without brachial plexus injury (BPI). ⋯ Neither antepartum nor intrapartum factors can differentiate the patient who will have shoulder dystocia with vs. without BPI.

Effect of maternal congenital heart defects on labor and delivery outcome: a population-based study.
The primary objective of this study was to characterize the delivery outcome of parturients with congenital heart defects (CHD), from maternal and from neonatal perspectives. ⋯ The labor outcome of CHD patients with NYHA classification I and II resembles that of non-CHD women in a tertiary center setting. Neonates of CHD mothers have higher rates of congenital malformations even among asymptomatic or mildly symptomatic mothers. A careful sonographic follow-up is warranted among all pregnancies of CHD patients.
