Effect of aspirin on maternal hemodynamics in Chinese women at high risk for preterm pre‐eclampsia: longitudinal study

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 5, Page 621-630, November 2025.
ABSTRACT Objectives To compare the maternal hemodynamics of Chinese women at low and at high risk for preterm pre‐eclampsia (PE) and assess the differences in hemodynamic parameters between high‐risk women with or without prophylactic aspirin. Methods This was a prospective longitudinal case–control study of 857 Chinese women with a singleton pregnancy

Role of aspirin therapy in modulating uterine artery resistance and placental growth between first and second trimesters of pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 5, Page 641-648, November 2025.
ABSTRACT Objective To evaluate the impact of low‐dose aspirin (LDA) on placental size and uterine artery pulsatility index (UtA‐PI) by analyzing longitudinal changes between the first and second trimesters in pregnancies at high risk for early‐onset pre‐eclampsia (PE).

Impact of race‐based customization on detection of fetal growth restriction

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 480-485, October 2025.
ABSTRACT Objective Fetal growth standards determine which fetuses are diagnosed with fetal growth restriction (FGR) and become candidates for enhanced fetal monitoring. Given the existence of race‐based differences in fetal and neonatal weights, we sought to determine the impact of race‐based customization of fetal growth curves on the antenatal ...

Outcome of monochorionic diamniotic twin pregnancy with selective fetal growth restriction and continuous or intermittent absent or reversed end‐diastolic umbilical artery flow: international multicenter cohort study

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 1, Page 41-50, July 2025.
ABSTRACT Objectives Monochorionic diamniotic (MCDA) twins with selective fetal growth restriction (sFGR) and either continuous (cAREDF) or intermittent (iAREDF) absent or reversed end‐diastolic flow in the umbilical artery face significant fetal and neonatal risks.

Aspirin delays preterm birth in pregnancies at high risk for preterm pre‐eclampsia: evidence from randomized clinical trial in Asia

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 1, Page 24-32, July 2025.
ABSTRACT Objectives To investigate the impact of aspirin administration on the incidence of preterm birth, according to the type of delivery and gestational age at preterm birth, and to examine the hypothesis that aspirin delays preterm delivery. Methods This was a secondary analysis of a multicenter stepped‐wedge cluster randomized trial of a first ...

Placental biomarker and fetoplacental Doppler abnormalities are strongly associated with placental pathology in pregnancies with small‐for‐gestational‐age fetus: prospective study

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 6, Page 749-760, June 2025.
ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

N‐terminal pro B‐type natriuretic peptide as biomarker to predict pre‐eclampsia and maternal–fetal complications

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 447-455, April 2025.
ABSTRACT Objective A soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio cut‐off of 38 is currently considered optimal for ruling out pre‐eclampsia (PE); however, implementation of this ratio in clinical practice is limited.
