In a population-based study, Diede Loopik and colleagues investigate associations between cervical intraepithelial neoplasia and risk of preterm birth among Dutch women.
New study shows that COVID-19 vaccines are safe in pregnancy
A new Northwestern Medicine study of placentas from patients who received the COVID-19 vaccine during pregnancy found no evidence of injury, adding to the growing literature that COVID-19 vaccines are safe in pregnancy.
The placenta is like the black box in an airplane. If something goes wrong with a pregnancy, we usually see changes in the placenta that can help us figure out what happened. From what we can tell, the COVID vaccine does not damage the placenta.

Ultrasound technique provides a new way to diagnose circulation problems in the placenta
A team of researchers funded by the National Institutes of Health has developed a new ultrasound technique to monitor the placenta for impaired fetal blood flow early in pregnancy. The technique, which uses conventional ultrasound equipment, relies on subtle differences in the pulsation of fetal blood through the arteries at the fetal and placental ends of the umbilical cord, potentially enabling physicians to identify placental abnormalities that impair fetal blood flow and, if necessary, deliver the fetus early. Like current ultrasound techniques, the new technique can also detect impaired flow of maternal blood through the placenta.
