Corpus Callosum Length and Cerebellar Vermian Height in Fetal Growth Restriction.

Introduction: Growth-restricted fetuses may have changes in their neuroanatomical structures that can be detected in prenatal imaging. We aim to compare corpus callosal length (CCL) and cerebellar vermian height (CVH) measurements between fetal growth restriction (FGR) and control fetuses and to correlate them with cerebral Doppler velocimetry in growth-restricted fetuses.

Methods: This was a prospective cohort of FGR after 20 weeks of gestation with ultrasound measurements of CCL and CVH.

Adverse perinatal outcomes in pregnancies affected by severe COVID-19 infection.

Background: Severe COVID-19 infection in pregnancy has been associated with an increase in adverse perinatal outcomes, although studies differ regarding which outcomes are affected. Increased characterization of obstetrical and neonatal outcomes is needed, including details on indications for preterm delivery and additional neonatal adverse outcomes.

Objective: This study aimed to determine whether there is a higher rate of adverse perinatal outcomes with severe-to-critical COVID-19 infection compared with nonsevere COVID-19 diagnosed during pregnancy.

Endocrine Emergencies During Pregnancy: Diabetic Ketoacidosis and Thyroid Storm.

The physiologic changes and common signs and symptoms of pregnancy can make the early recognition of endocrine emergencies more challenging. Diabetic ketoacidosis (DKA) can occur at only modestly elevated glucose levels (euglycemic DKA), often accompanied by starvation ketosis due to substantial fetal-placental glucose demands and is associated with a high stillbirth rate. Thyroid storm is life threatening with a higher rate of heart failure and both require prompt and aggressive treatment to avoid maternal and fetal morbidity and mortality.

Umbilical Venous Volume Flow in Late-Onset Fetal Growth Restriction.

Objectives: Umbilical vein flow (UVF) is reduced in fetal growth restriction (FGR). We compared absolute and size-adjusted UVF (estimated fetal weight [EFW] and abdominal circumference [AC]) and rates of abnormal UVF parameters (<10th percentile) among FGR fetuses meeting Delphi criteria (FGR-D) against small for gestational age (SGA) fetuses and appropriate for gestational age (AGA) controls.

Methods: Absolute UVF, UVF/EFW, and UVF/AC were compared between 73 FGR pregnancies (35 FGR-D, 38 SGA) and 108 AGA controls.

Accuracy of fetal anatomy survey in the diagnosis of velamentous cord insertion: a case-control study.

Objective: Our objective was to determine the accuracy of ultrasound at the time of the fetal anatomy survey in the diagnosis of velamentous cord insertion (VCI).

Study Design: This retrospective case-control study identified placentas with VCI (cases) and randomly selected placentas with normal placental cord insertion (PCI) (controls) as documented by placental pathology for mothers delivered from 2002 through 2015. Archived ultrasound images for PCI at the time of the fetal anatomy survey were reviewed.

Placental thickness on ultrasound and neonatal birthweight.

Objective To investigate the relationship between maximal placental thickness during routine anatomy scan and birthweight at delivery. Methods This retrospective descriptive study analyzed 200 term, singleton deliveries in 2016 at Penn State Hershey Medical Center. We measured maximal placental thickness in the sagittal plane from the ultrasound images of the placenta obtained at the 18-21-week fetal anatomy screen.

High Self-Efficacy Is Associated with Prescription Contraceptive Use.

Objectives: In the United States, 45% of pregnancies continue to be unintended. Although many previous studies have focused on external barriers to contraceptive use such as cost or access, fewer studies have evaluated internal barriers such as individual characteristics. We hypothesize that high self-efficacy for contraception will be associated with use of more effective contraceptive methods.
