Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.
ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.

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

open access: yesUltrasound 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

妊娠梅毒孕期内和妊娠前抗梅毒治疗对分娩结果的影响 [PDF]

open access: yes, 2006
【目的】探讨妊娠梅毒孕期内和妊娠前抗梅毒治疗对分娩结果的不同影响。【方法】将梅毒孕妇按其发现和治疗时间是在妊娠期内还是妊娠期前分为观察Ⅰ组与观察Ⅱ组,观察Ⅰ组是在妊娠时发现梅毒进行正规的青霉素抗梅毒治疗,观察Ⅱ组是已接受正规青霉素治疗后才怀孕。【结果】观察Ⅰ组165例中。9例Ⅰ期梅毒患者治疗均成功分娩产出活婴,14例Ⅱ期梅毒患者治疗成功11例,142例潜伏梅毒患者治疗成功136例;各期梅毒患者总的治疗成功率94.5%(156/165)。观察Ⅰ组经过足量治疗后所生新生儿中。梅毒血清阳性率为20.6%(34/

单胚胎移植临床结局分析

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2019
【目的】探讨辅助生殖领域单胚胎移植(SET)的应用前景。【方法】回顾性分析我院生殖中心近两年进行SET的5130例新鲜与冷冻移植周期资料。对新鲜、冷冻周期分别进行比较,并分成选择性和被迫性SET亚组,对比患者的不同胚胎类型、不同年龄段在新鲜与冷冻周期情况下的临床妊娠结局。【结果】在非植入前遗传学检测(PGT)选择性SET周期中,35岁前移植第3天胚胎(D3)和第6天胚胎(D6)的临床妊娠率高达30%,第5天胚胎(D5)的临床妊娠率可高达50%;在PGT周期,小于42岁的患者临床妊娠率可达45 ...
