Hypertension at 5 months postpartum in women with gestational diabetes

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 202-210, August 2026.
ABSTRACT Objective Gestational diabetes mellitus (GDM) is associated with future maternal cardiovascular disease, independent of the development of Type‐2 diabetes mellitus. As a major cardiovascular risk factor, we examined the incidence and predictors of hypertension at 5 months postpartum in women with previous GDM.

First‐trimester prediction and prevention of preterm pre‐eclampsia in women with chronic hypertension

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 613-622, May 2026.
ABSTRACT Objectives To evaluate the effect of aspirin on gestational age at delivery due to preterm pre‐eclampsia (PE) in women with chronic hypertension (CH), to assess the predictive performance of the Fetal Medicine Foundation (FMF) first‐trimester competing‐risks model for preterm PE in this high‐risk group and to evaluate how parity, previous PE ...

External validation of QUiPP App in three independent European cohorts of symptomatic women

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 2, Page 163-174, August 2025.
ABSTRACT Objective To validate externally the QUantitative Innovation in Predicting Preterm birth (QUiPP) App v.2 for the prediction of spontaneous preterm birth (sPTB) in symptomatic women attending tertiary care in Europe. Methods The QUiPP App v.2 was validated in three independent datasets: a prospective European multicenter cohort across five ...

Prediction of pre‐eclampsia using maternal hemodynamic parameters at 12 + 0 to 15 + 6 weeks

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 2, Page 173-182, February 2025.
ABSTRACT Objectives To compare the maternal hemodynamic profile at 12 + 0 to 15 + 6 weeks' gestation in women who subsequently developed pre‐eclampsia (PE) and those who did not, and to assess the screening performance of maternal hemodynamic parameters for PE in combination with the Fetal Medicine Foundation (FMF) triple test, including maternal ...

弱视患者的曲线轮廓整合能力

, 2017
目的：大量研究表明弱视患者的轮廓整合能力比正常人弱。但是他们的研究基本上采用直线段的方式，很少有人研究曲度对轮廓整合能力的影响。 方法：有效刺激为由多个小Gabor光栅（个数已设置为预先实验的最优参数）规则排列组成的曲线段隐含在杂乱排列的相同参数Gabor光栅构成的背景中。曲线的曲度从45°到180°，间隔45°。对比刺激为全部杂乱排列的Gabor光栅，即不存在合理的曲线段。刺激呈现的时间为100/200/300/400ms。被试需要在该呈现时间内甄别出有无曲线段的存在。

Routine 36‐week scan: prediction of small‐for‐gestational‐age neonate

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 1, Page 20-29, January 2025.
ABSTRACT Objectives First, to compare the predictive performance of routine ultrasonographic estimated fetal weight (EFW) at 31 + 0 to 33 + 6 and 35 + 0 to 36 + 6 weeks' gestation for delivery of a small‐for‐gestational‐age (SGA) neonate.
