Ultrasound Obstet Gynecol
January 2025
Objective: To compare the accuracy of four published reference standards for the umbilical artery pulsatility index (UA-PI) in predicting small-for-gestational age (SGA), adverse neonatal outcomes and obstetric complications in pregnancies at risk for fetal growth restriction.
Methods: This was a secondary analysis of a prospective study of singleton pregnancies that underwent fetal growth assessment by ultrasound between 26 and 36 weeks' gestation. Pregnancies with estimated fetal weight or abdominal circumference < 20 percentile with UA-PI measurements available were included.
Objective: Untreated opioid use disorder (OUD) is associated with significant morbidity in pregnancy. Recent reports have highlighted the rise of xylazine in the nonprescribed fentanyl supply. The frequency with which pregnant people with OUD are exposed to xylazine has not been characterized.

This study evaluates the association between first trimester physical activity, assessed by Kaiser Physical Activity Survey (KPAS) scores, and adverse perinatal outcomes.
Study Design: This is a secondary analysis of a prospective cohort study in which patients were administered the KPAS in each trimester.

However, in clinical practice, digital exams may be necessary. We examined whether increasing numbers of digital exams were associated with adverse outcomes in PPROM.
