Abstract Acute fatty liver of pregnancy (AFLP) is a rare but critical obstetric-specific disease with a high fatality rate, posing a serious threat to the safety of mothers and infants. These guidelines were specially formulated to standardize AFLP clinical pathways and to improve maternal and infant outcomes. Based on a two-round questionnaire survey, the guideline development team identified the following nine clinical issues that clinicians were most concerned about, and developed recommendations for each of them: prenatal outpatient screening for AFLP, diagnosis, preoperative risk assessment, delivery modes and timing, anesthesia methods, perinatal complications, selecting AFLP patients for artificial liver treatment, prognostic assessment, and monitoring during treatment. The guidelines cover the key issues related to AFLP diagnosis and treatment that concern clinicians.
摘要妊娠期急性脂肪肝(AFLP)是一种罕见但危重的产科特异性疾病,病死率高,严重威胁母婴安全。这些指南是专门制定的,以标准化AFLP临床途径,并改善母婴结局。基于两轮问卷调查,指南制定团队确定了临床医生最关心的以下九个临床问题,并为每一个问题制定了建议:AFLP的产前门诊筛查、诊断、术前风险评估、分娩方式和时间、麻醉方法、围产期并发症,选择AFLP患者进行人工肝治疗、预后评估和治疗期间的监测。该指南涵盖了临床医生关注的AFLP诊断和治疗的关键问题。

Abstract Objective: To investigate the efficacy of in-phase and quadrature (IQ) demodulation in electronic fetal heart rate monitoring (EFM) to reduce false reports of fetal heart rate (FHR) doubling or halving. Methods: This is a prospective cohort study. A total of 263 full-term pregnant women who delivered at Peking University Shenzhen Hospital between August 2019 and July 2020 were prospectively enrolled in the study. FHR monitoring began when the cervix was dilated to 2–3  cm and continued until delivery. Raw fetal Doppler audio signals and internal and external cardiotocography curves from internal electrode monitoring, EFM with conventional demodulation (external), and EFM with IQ demodulation (external) were acquired to compare FHR doubling and halving time. In cohort 1, FHR was compared between IQ demodulation and conventional demodulation. In cohort 2, FHR was compared between IQ demodulation, conventional demodulation, and internal FHR monitoring. Count data were statistically analyzed using the Chi-squared test, and measurement data were statistically analyzed using t-test for correlation coefficients, and Bland-Altman analysis for concordance ranges. Results: To compare IQ demodulation and conventional demodulation, 225 pregnant women were monitored for a total of 835,870  seconds. The beat-to-beat interval of FHRs in raw fetal Doppler audio signals was used as the reference. The results showed a doubling time of 3401  seconds (0.407%, 3401/835,870) and a halving time of 2918  seconds (0.349%, 2918/835,870) with conventional demodulation, compared to 241  seconds (0.029%, 241/835,870) and 589  seconds (0.070%, 589/835,870), respectively, with IQ demodulation. IQ demodulation reduced FHR doubling by approximately 93% (3160/3401) and FHR halving by approximately 80% (2329/2918) compared to conventional demodulation (P < 0.01). To compare IQ demodulation, conventional demodulation, and internal FHR monitoring, 38 pregnant women were monitored for a total of 98,561  seconds. FHR from internal electrode monitoring was used as the reference. The results showed a doubling time of 238  seconds (0.241%, 238/98,561) and a halving time of 235  seconds 0.238%, 235/98,561) with conventional demodulation, compared with 30  seconds (0.030%, 30/98,561) and 81  seconds (0.082%, 81/98,561), respectively, with IQ demodulation (P < 0.05). No significant difference was observed in doubling or halving time between IQ demodulation and internal FHR monitoring (P > 0.05). IQ demodulation was more closely correlated with internal FHR monitoring than conventional demodulation (0.986 vs. 0.947). The Bland-Altman analysis showed that the concordance range of IQ demodulation vs. internal FHR monitoring was significantly narrower than that of conventional demodulation vs. internal FHR monitoring ((−5.32,6.01) vs. (−10.87,11.46)). Conclusion: EFM with IQ demodulation significantly reduces false FHR doubling and halving, with an efficacy similar to that of internal
摘要目的:探讨电子胎心率监测(EFM)中同相正交(IQ)解调对减少胎心率(FHR)加倍或减半误报的有效性。方法:这是一项前瞻性队列研究。共有263名在2019年8月至2020年7月期间在北京大学深圳医院分娩的足月孕妇前瞻性地参与了这项研究。FHR监测始于宫颈扩张至2-3  cm,并持续到分娩。采集来自内部电极监测、常规解调的EFM(外部)和IQ解调的EFM-(外部)的原始胎儿多普勒音频信号和内部和外部心描记图曲线,以比较FHR加倍和减半时间。在队列1中,比较IQ解调和常规解调之间的FHR。在队列2中,比较IQ解调、常规解调和内部FHR监测之间的FHR。计数数据使用卡方检验进行统计分析,测量数据使用相关系数的t检验和一致性范围的Bland-Altman分析进行统计分析。结果:为了比较IQ解调和常规解调,225名孕妇接受了监测,共835870人  秒。原始胎儿多普勒音频信号中FHR的拍间间隔用作参考。结果显示加倍时间为3401  秒(0.407%,3401/835870)和2918的减半时间  秒(0.349%,2918/835870),而传统解调为241  秒(0.029%,241/835870)和589  秒(0.070%,589/835870)。与传统解调相比,IQ解调使FHR加倍减少了约93%(3160/3401),FHR减半减少了约80%(2329/2918)(P  与常规解调相比,IQ解调与内部FHR监测的相关性更为密切(0.986 vs.0.947)。Bland-Altman分析表明,IQ解调对内部FHR监控的一致性范围明显窄于常规解调对内部跳频监测的一致性范围(−5.32,6.01)vs.(−10.87,11.46))。结论:具有IQ的EFM解调显著减少了错误的FHR加倍和减半,其效果类似于内部FHR监测。

Abstract The effects of gestational diabetes mellitus (GDM) on offspring include macrosomia, hypoglycemia, respiratory distress syndrome, cardiovascular disease, neural and mental injury, etc. The effects of GDM on the health status of offspring are sustained although pregnancy has ended. It has been proposed that fetal reprogramming causes long-term consequences to metabolic health in offspring. An intrauterine high-glucose environment may lead to changes in the multi-differentiation proficiency of intracorporal stem cells, showing decreased proliferation and osteogenic ability, increased adipogenic ability, accelerated apoptosis, and occurrence of premature failure. This environment also reduces the mobilization of bone marrow stem cells, whereas it increases that of medullary cells. This results in pro-inflammatory conditions and sustained inflammation in the body, thereby increasing the risk of obesity, cardiovascular and neurological disorders, and metabolic abnormalities. Stem cells derived from the amniotic membrane, umbilical cord, or placenta may be a reliable predictor of the long-term effects of GDM on offspring. The levels of blood glucose during pregnancy should be effectively controlled to reduce harm to the neonate.
摘要妊娠期糖尿病(GDM)对后代的影响包括巨大儿、低血糖、呼吸窘迫综合征、心血管疾病、神经和精神损伤等。尽管妊娠已经结束,但GDM对后代健康状况的影响是持续的。有人提出,胎儿重新编程会对后代的代谢健康产生长期影响。宫内高糖环境可能导致体内干细胞的多向分化能力发生变化,表现出增殖和成骨能力下降、成脂能力增加、细胞凋亡加速和过早衰竭的发生。这种环境也减少了骨髓干细胞的动员,而增加了骨髓细胞的动员。这会导致体内出现促炎状态和持续炎症,从而增加肥胖、心血管和神经系统疾病以及代谢异常的风险。来自羊膜、脐带或胎盘的干细胞可能是GDM对后代长期影响的可靠预测因子。应有效控制妊娠期间的血糖水平,以减少对新生儿的伤害。

Abstract Maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the second and third trimesters of pregnancy may impact fetal development via vertical transmission, complications of coronavirus disease 2019 (COVID-19), or placental injury. However, potential associations between prenatal SARS-CoV-2 infection and fetal loss are not well understood. This case series of thirteen second and third trimester fetal losses reported by local public health departments to California's state public health surveillance included maternal clinical and demographic characteristics as well as placental pathology, fetal autopsy reports, and coroner report. There was no evidence that maternal COVID-19 disease severity, placental injury, or SARS-CoV-2 vertical transmission contributed to pregnancy loss. However, this case series is a limited sample; more research is needed to identify factors of prenatal SARS-CoV-2 that may contribute to fetal death in the second and third trimesters.
妊娠中期和晚期母体感染严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)可能通过垂直传播、2019年冠状病毒病(COVID-19)并发症或胎盘损伤影响胎儿发育。然而,产前SARS-CoV-2感染与胎儿流产之间的潜在关联尚不清楚。当地公共卫生部门向加利福尼亚州公共卫生监测部门报告的13例妊娠中期和晚期胎儿丢失病例包括产妇临床和人口统计学特征以及胎盘病理、胎儿尸检报告和验尸报告。没有证据表明母体COVID-19疾病严重程度、胎盘损伤或SARS-CoV-2垂直传播导致妊娠丢失。然而,这个案例系列是一个有限的样本;需要更多的研究来确定产前SARS-CoV-2可能导致妊娠中期和晚期胎儿死亡的因素。

Abstract Umbilical cord (UC) embolism is a rare, life-threatening complication of pregnancy. The exact cause of this condition is not yet known. Women with more than one UC abnormality are at risk of UC obstruction; this condition can lead to stasis, ischemia, and in some cases, thrombosis. However, many women with UC abnormalities remain undetected and may not be recognized until after birth. Here, we present a case involving the prenatal diagnosis and successful treatment of umbilical artery embolism in the third trimester with good maternal and fetal outcomes. The risk of UC embolism increases when more than one UC abnormality is identified in a single case. Ultrasound examination in the third trimester of pregnancy should be able to verify the existence of two arteries and one vein in the UC. If necessary, these results can be compared with ultrasound imaging acquired during the first trimester of pregnancy.
摘要脐带栓塞是一种罕见的、危及生命的妊娠并发症。这种情况的确切原因尚不清楚。患有一种以上UC异常的女性有患UC梗阻的风险;这种情况会导致淤血、局部缺血,在某些情况下还会导致血栓形成。然而,许多UC异常的女性仍然没有被发现,可能直到出生后才能被识别。在这里,我们介绍了一个案例,涉及妊娠晚期脐动脉栓塞的产前诊断和成功治疗,具有良好的母体和胎儿结局。当在一个病例中发现一个以上的UC异常时,UC栓塞的风险会增加。妊娠晚期的超声检查应该能够验证UC中是否存在两条动脉和一条静脉。如有必要,可以将这些结果与妊娠早期获得的超声成像进行比较。

Abstract Objective To build a reference fetal growth chart for the Chinese population based on fetal ultrasound measurements. Methods This was a multicenter, population-based retrospective cohort study. Longitudinal ultrasound measurement data were collected from 24 hospitals in 18 provinces of China from 1st September through 31st October of 2019. The estimated fetal weight (EFW) was calculated based on head circumference, abdominal circumference, and femur length using Hadlock formula 3. Fetal growth curves were estimated using a two-level linear regression model with cubic splines. All participants were divided into two groups: the northern group (n = 5829) and the southern group (n = 3246) based on the geographical division of China and male fetus group (n = 4775) and female fetus group (n = 4300) based on fetal gender. The EFW was compared by fetal gender and geographical group. All statistical models were adjusted for maternal sociodemographic characteristics. Results A total of 9075 participants with 31,700 ultrasound measurement records were included in this study. Male fetuses demonstrated significantly larger EFW compared to female ones starting at 16 weeks of gestation and extending to delivery (global test P < 0.01). The overall geographic difference in EFW was significant (global test P = 0.03), and week-specific comparisons showed that the northern group had a greater EFW starting at 15 weeks of gestation and extending to 29 weeks of gestation, although this difference did not extend to the time of delivery. The Z-score of EFW confirmed that our Chinese fetal growth charts differed from previously published standards. Conclusion This study provides EFW and ultrasound biometric reference measurements for Chinese fetuses and reveals differences from other fetal growth charts. The chart is worth promoting in more regions of China but should be tested prudently before use.
【摘要】目的基于胎儿超声测量,建立适用于中国人群的参考胎儿生长图。方法本研究是一项多中心、以人群为基础的回顾性队列研究。纵向超声测量数据收集自2019年9月1日至10月31日,来自中国18个省份的24家医院。根据头围、腹围和股骨长度,采用Hadlock公式3计算胎儿体重。采用三次样条双水平线性回归模型估计胎儿生长曲线。所有参与者根据中国的地理划分和胎儿性别分为北方组(n = 5829)和南方组(n = 3246),男性胎儿组(n = 4775)和女性胎儿组(n = 4300)。按胎儿性别和地域分组比较EFW。所有统计模型都根据产妇的社会人口学特征进行了调整。结果共纳入受试者9075人,超声测量记录31700份。从妊娠16周开始至分娩时,男性胎儿的EFW显著高于女性胎儿(全检P < 0.01)。EFW的总体地理差异是显著的(全球检验P = 0.03),周特异性比较显示,北方组的EFW在妊娠15周开始并延伸到妊娠29周,尽管这种差异没有延伸到分娩时间。EFW的Z-score证实了我们的中国胎儿生长图表与先前公布的标准不同。结论本研究为中国胎儿提供了EFW和超声生物特征参考指标,揭示了与其他胎儿生长指标的差异。该图表值得在中国更多地区推广,但在使用前应谨慎测试。

Methods This was a multicenter, population-based retrospective cohort study. Longitudinal ultrasound measurement data were collected from 24 hospitals in 18 provinces of China from 1st September through 31st October of 2019. The estimated fetal weight (EFW) was calculated based on head circumference, abdominal circumference, and femur length using Hadlock formula 3. Fetal growth curves were estimated using a two-level linear regression model with cubic splines. All participants were divided into two groups: the northern group (n = 5829) and the southern group (n = 3246) based on the geographical division of China and male fetus group (n = 4775) and female fetus group (n = 4300) based on fetal gender. The EFW was compared by fetal gender and geographical group. All statistical models were adjusted for maternal sociodemographic characteristics. Results A total of 9075 participants with 31,700 ultrasound measurement records were included in this study. Male fetuses demonstrated significantly larger EFW compared to female ones starting at 16 weeks of gestation and extending to delivery (global test P < 0.01). The overall geographic difference in EFW was significant (global test P = 0.03), and week-specific comparisons showed that the northern group had a greater EFW starting at 15 weeks of gestation and extending to 29 weeks of gestation, although this difference did not extend to the time of delivery. The Z-score of EFW confirmed that our Chinese fetal growth charts differed from previously published standards. Conclusion This study provides EFW and ultrasound biometric reference measurements for Chinese fetuses and reveals differences from other fetal growth charts. The chart is worth promoting in more regions of China but should be tested prudently before use.","PeriodicalId":74121,"journal":{"name":"Maternal-fetal medicine (Wolters Kluwer Health, Inc.)","volume":"5 1","pages":"16 - 26"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41962809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Objective: To investigate the effects of spontaneous labor before elective repeat cesarean delivery (ERCD) on short-term maternal and neonatal outcomes. Methods: This was a prospective cohort study. All consecutive ERCDs, occurring at ≥37  weeks of gestation between July 1, 2017 and December 31, 2019 in Makassed General Hospital, were evaluated. The maternal and neonatal outcomes of 183 laboring women undergoing unscheduled repeat cesarean delivery (URCD) group were compared with those of 204 women undergoing cesarean delivery (CD) without spontaneous labor (ERCD) group. Primary outcomes were “composite adverse maternal outcome” and “composite adverse neonatal outcome.” Fisher's exact and Student's t tests were used to assess the significance of differences in dichotomous and continuous variables, respectively. Two logistic regression models were constructed to identify risk factors with most significant influence on the rate of composite adverse maternal and neonatal outcomes. Results: “Composite adverse maternal outcome” was significantly more common in women who underwent spontaneous labor ((40/183) 21.9% vs. (19/204) 9.3%, P = 0.001, relative risk (RR): 2.7, 95% confidence interval (CI): 1.50–4.90). Similarly, “composite adverse neonatal outcome” was significantly increased in the URCD group ((24/183) 13.1% vs. (12/204) 5.9%, P = 0.014, RR: 2.4, 95% CI: 1.18–4.98). These adverse effects persisted after adjustment for confounders. Multivariate regression models revealed that, besides labor, CD-order impacted maternal outcome (RR: 1.5, 95%CI: 1.02–2.30, P = 0.036), while CD-order and teenage pregnancy influenced neonatal outcome (RR: 2.1, 95%CI: 1.29–3.38, P = 0.003, and RR: 16.5, 95%CI: 2.09–129.80, P = 0.008, respectively). Conclusion: In our study, spontaneous labor before ERCD, including deliveries at term, was associated with adverse maternal and neonatal outcomes, indicating that it is preferable to conduct ERCD before the onset of labor. Screening women with MRCD may identify those at increased risk for spontaneous labor for whom CD could be scheduled 1–2 weeks earlier. Further large prospective studies to assess the effects of such an approach on maternal and neonatal outcomes are strongly warranted.
摘要目的:探讨选择性重复剖宫产术(ERCD)前顺产对产妇和新生儿短期结局的影响。方法:这是一项前瞻性队列研究。所有连续的ERCD,发生在≥37  对2017年7月1日至2019年12月31日在马卡塞斯综合医院的妊娠周进行了评估。将183名接受计划外重复剖宫产(URCD)的分娩妇女的产妇和新生儿结局与204名接受无自然分娩(ERCD)的剖宫产妇女的产妇及新生儿结局进行比较。主要结果为“母体复合不良反应结果”和“新生儿复合不良反应”。Fisher精确检验和Student t检验分别用于评估二分变量和连续变量差异的显著性。构建了两个逻辑回归模型,以确定对孕产妇和新生儿复合不良结局发生率影响最大的风险因素。结果:“复合不良产妇结局”在顺产妇女中更为常见((40/183)21.9%对(19/204)9.3%,P = 0.001,相对风险(RR):2.7,95%置信区间(CI):1.50–4.90)。同样,URCD组的“新生儿综合不良反应”显著增加((24/183)13.1%对(12/204)5.9%,P = 0.014,RR:2.4,95%CI:1.18-4.98)。这些不良反应在校正混杂因素后持续存在。多变量回归模型显示,除分娩外,CD顺序还影响产妇结局(RR:1.5,95%CI:1.02–2.30,P = 0.036),而CD顺序和青少年妊娠影响新生儿结局(RR:2.1,95%CI:1.29-3.38,P = 0.003,RR:16.5,95%CI:2.09-129.80,P = 分别为0.008)。结论:在我们的研究中,ERCD前的顺产,包括足月分娩,与不良的孕产妇和新生儿结局有关,表明最好在分娩前进行ERCD。对患有MRCD的妇女进行筛查可以确定那些自发性分娩风险增加的妇女,可以提前1-2周安排CD。有必要进一步进行大型前瞻性研究,以评估这种方法对孕产妇和新生儿结局的影响。

Abstract Posterior placenta accreta spectrum (PAS) disorders are infrequent but potentially associated with significant maternal mortality and morbidity, especially if not diagnosed prenatally. Analysis of published literature is problematic since most experiences included only a few cases. Knowledge of the risk factors associated with posterior PAS is crucial to identifying mothers at higher risk and ask for high sensitivity studies. Ultrasound has poor diagnostic accuracy in detecting posterior PAS, while magnetic resonance imaging better delineates the posterior uterine wall. In comparison, prenatal imaging's diagnostic performance in detecting posterior PAS is significantly lower than anterior placenta invasion. Management of posterior PAS depends on several factors, including maternal hemodynamic status, available resources, clinical presentation, and invasion severity. For accreta or increta cases, a compression suture is habitually enough to perform hemostasis. Nevertheless, organ involvement habitually requires a multidisciplinary team with the assistant of a general or coloproctology surgeon. The present article aims to update the risk factors, prenatal diagnosis, and surgical management of pregnancies complicated by posterior PAS.
摘要后胎盘植入谱(PAS)疾病并不常见,但可能与显著的孕产妇死亡率和发病率有关,尤其是在未经产前诊断的情况下。对已发表文献的分析是有问题的,因为大多数经验只包括少数案例。了解与后PAS相关的风险因素对于识别风险较高的母亲并要求进行高灵敏度研究至关重要。超声在检测后PAS方面的诊断准确性较差,而磁共振成像可以更好地描绘子宫后壁。相比之下,产前影像学在检测后部PAS方面的诊断性能明显低于前部胎盘侵犯。后部PAS的治疗取决于几个因素,包括母体血液动力学状况、可用资源、临床表现和侵袭严重程度。对于增生或肠增的病例,压迫缝合通常足以止血。然而,器官受累通常需要一个多学科团队,由普通或结肠直肠外科医生协助。本文旨在更新妊娠合并后PAS的危险因素、产前诊断和手术治疗。
