SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study

Ultrasound in Obstetrics &Gynecology, Volume 62, Issue 6, Page 867-874, December 2023., 2023
ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.

Cost–benefit analysis of first‐trimester pre‐eclampsia screening: comparison of multivariable Gaussian algorithm with and without placental growth factor

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 162-167, February 2026.
ABSTRACT Objective Pre‐eclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Early identification of high‐risk pregnancies in the first trimester allows preventive treatment with low‐dose aspirin. This study aimed to evaluate whether multivariable Gaussian algorithm‐based PE screening strategies, with and without

Prenatal Exposure to Airborne Particulate Matter on the Development of Heart in Rat Fetus [PDF]

, 2015
大气颗粒物（ParticulateMatter，PM）是指悬浮在大气中的固体、液体颗粒物的总称。不同来源的颗粒物形成条件不同，其粒径分布、化学组成也不同。目前国际公认的对人类健康危害较大且研究较多的大气颗粒污染物是PM2.5（FineParticulateMatter）和PM10（InhalableParticulateMatter）[1]。越来越多的证据表明，PM严重威胁着人体的健康，更对孕妇及胎儿的发育产生不良影响，导致出生缺陷儿增多，使出生人口质量下降，增加死亡率。因此 ...

母胎界面微环境改变与早产 [PDF]

, 2018
妊娠第37周前分娩的现象被称为早产。目前,全球每年约有1500万早产儿出生,其中100万早产儿在出生后的1个月内死亡。因此,早产作为一个全球性的问题,为社会带来了严重的负担。探索早产发生的机制,寻找有效的预防方法,是目前亟待解决的科学问题。文章围绕影响母胎界面微环境的3个主要因素即胎儿滋养层细胞、子宫蜕膜和母胎界面免疫细胞,详细阐述母胎界面微环境改变在早产发生中的作用机制。国家重点研发计划 ...

Comparison of open fetal, fetoscopic and postnatal surgical repair for open spina bifida: decision analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 433-442, October 2025.
ABSTRACT Objective Currently, there are several surgical approaches to manage fetal open spina bifida (OSB), namely postnatal surgical repair, open fetal surgery and its minimally invasive alternative, fetoscopic repair. Our objective was to determine the optimal surgical approach for OSB, weighing the benefits and risks to the fetus and the pregnant ...
