Hemoglobin A1c as a Substitute for Oral Glucose Testing in Early Pregnancy Screening.

Objective: Current recommendations for individuals with risk factors for gestational diabetes mellitus (GDM) call for screening in early pregnancy. However, there is currently no clear consensus on a specific screening modality. This study evaluates whether a hemoglobin A1c (HbA1c) screening in individuals with risk factors for gestational diabetes (GDM) could be used instead of an early 1-hour glucose challenge test (GCT).

The impact of trimester of COVID-19 infection on pregnancy outcomes after recovery.

Objectives: Many physiological adaptations occur during pregnancy. It is not currently known how timing of COVID-19 infection impacts pregnancy. We hypothesize that maternal and neonatal outcomes are different if COVID-19 infection occurs in different trimesters of pregnancy.

Third Trimester Ultrasound Stratifies Risk of Peripartum Complications in Pregnancies Complicated by Impaired Glucose Tolerance.

Objective: The objective of our study was to investigate the effect of impaired glucose metabolism (IGM) and ultrasound (US) findings consistent with hyperglycemia on maternal and neonatal outcomes.

Study Design: This was a retrospective case-control study of singleton, nonanomalous pregnancies with an elevated 1-hour glucose screening test (GST) completed after 23 weeks of gestation. IGM was defined as a 1-hour GST of >130, but less than two abnormal values on 3-hour glucose tolerance test (GTT).

COVID-19 Barriers to Care for Pregnant Patients in Prolonged Isolation.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent responsible for coronavirus disease 2019 (COVID-19), continues to have a devastating impact on healthcare systems worldwide, and many questions remain unanswered. The effect of COVID-19 on the pregnant population is widely debated, and the unique risks in pregnancy have not yet been elucidated. What has been established, however, is the recommendation for healthcare workers to use personal protective equipment (PPE) for both contact and airborne precautions to prevent transmission of the pathogen-adding another barrier to care for vulnerable populations.

Marijuana use and pregnancy: prevalence, associated characteristics, and birth outcomes.

This study examines the prevalence, behaviors, and birth outcomes associated with marijuana use in pregnancy. This was a retrospective cohort from a university-based prenatal care clinic from July 1, 2009 to June 30, 2010. The primary exposure was marijuana use, defined by self-report or urine toxicology.

A comparison of Doppler and biophysical findings between liveborn and stillborn growth-restricted fetuses.

Objective: The purpose of this study was to evaluate the surveillance characteristics that precede stillbirth in growth-restricted fetuses that receive integrated Doppler and biophysical profile scoring (BPS).

Study Design: Nine hundred eighty-seven singleton pregnancies that were complicated by fetal growth restriction had multivessel Doppler scans (umbilical and middle cerebral arteries [MCA], ductus venosus, and umbilical vein) and BPS. Surveillance findings were compared between live births and stillbirths.
