The iatrogenic left shift in the gestational age distribution at term and post-term gestation that has occurred in recent decades has had a positive impact on both stillbirth and SIDS.
Gestational diabetes mellitus (GDM) is defined as a state of hyperglycemia arising during gestation that leads to increased glucose delivery to the developing fetus.
Results: Providers were least knowledgeable regarding the definition of stillbirth and the number of weeks' gestation that constitute a stillbirth.
Systematic evaluation and estimation of growth trajectories in twins require ultrasound measurements across gestation that are performed in controlled clinical settings.
Study Design: Pregnancies complicated by PPROM at ≤14 31 weeks' gestation that developed an active recurrent genital herpes lesion were collected.
To describe a case of twin gestation that occurred in both horns of a bicornuate uterus after the administration of clomiphene citrate and bromocriptine.
Study Design: This was a historic cohort study of 194 triplet pregnancies of ≥24 weeks of gestation that were delivered from 1983 through 2001 from five medical centers.
There was a linear increase in cardiac preload and relative pulse amplitude in the IVC with gestation that correlated significantly with the presence of end-diastolic flow in the pulmonary artery and improvement in right ventricular diastolic function.
Receiver operating characteristic curve analysis was used to determine the ultrasonographic cervical parameter evaluated at 15 to 20 weeks' gestation, 21 to 24 weeks' gestation, and 25 to 28 weeks' gestation that were best for prediction of spontaneous preterm birth at <28 weeks' gestation, <30 weeks' gestation, <32 weeks' gestation, and <34 weeks' gestation.
The absolute number of births at 37 to 39 weeks of gestation (by last normal menstrual period) that were reclassified as preterm (n = 1206 births) was much higher than the number of preterm births at 34 to 36 weeks of gestation that were reclassified as term (n = 581 births).
Risk factors for cervical incompetence included previous preterm delivery before 34 weeks of gestation that met clinical criteria for the diagnosis of cervical incompetence, previous preterm premature rupture of membranes before 32 weeks of gestation, history of cold knife conization, diethylstilbestrol exposure, and uterine anomaly.
