The prophylactic use of low-dose aspirin for prevention of preeclampsia has been an important research question in obstetrics for the last three decades. In 1979, Crandon and Isherwood observed that nulliparous women who had taken aspirin regularly during pregnancy were less likely to have preeclampsia than women who did not. In 1985, Beaufils et al published the first randomized trial suggesting that 150 mg aspirin and 300 mg dipyridamole daily from 3 months’ gestation onwards decreased the risk of preeclampsia, fetal growth restriction and stillbirth in high-risk women. Subsequently, more than 50 trials have been carried out throughout the world and a meta-analysis of these studies reported that the administration of low-dose aspirin in high-risk pregnancies is associated with a decrease in the rate of preeclampsia by approximately 10%. Consequently, several national professional bodies recommend that high-risk pregnancies should be treated with aspirin (50–150 mg daily).
预防性使用低剂量阿司匹林预防先兆子痫一直是一个重要的研究问题在产科在过去的三十年。1979年,克兰登和伊舍伍德观察到,怀孕期间定期服用阿司匹林的未生育妇女患先兆子痫的可能性低于未服用阿司匹林的妇女。1985年,Beaufils等人发表了第一项随机试验,表明从妊娠3个月起每天服用150毫克阿司匹林和300毫克双嘧达莫可降低高危妇女发生先兆子痫、胎儿生长受限和死胎的风险。随后,在世界各地进行了50多项试验,对这些研究的荟萃分析报告称,在高危妊娠中使用低剂量阿司匹林可使先兆子痫发生率降低约10%。因此,一些国家专业机构建议高危妊娠应服用阿司匹林(每日50-150毫克)。

APPENDICITIS IN PREGNANCY 妊娠期阑尾炎
Pub Date : 2012-11-01 DOI: 10.1017/S0965539512000149
C. Windrim, M. Czikk
Acute appendicitis is the most common non-obstetric indication for surgical intervention in pregnancy, complicating 1/500 to 1/2000 deliveries. Due to the anatomical and physiological changes associated with pregnancy, appendicitis may present a diagnostic dilemma, leading to management delays and thus increasing the risk of appendiceal perforation. Many of the common presenting symptoms of appendicitis are common features of normal pregnancy including lower abdominal pain, nausea, vomiting and leukocytosis. Furthermore, the enlarging gravid uterus may displace the appendix to varying degrees thus altering the classic symptom pattern of appendicitis. The often nonspecific presentation in pregnancy may necessitate the utilization of diagnostic imaging to aid in accurate diagnosis. However, the perforated appendix is the most common surgical cause of fetal loss and the time required for any diagnostic aid must be weighed against the increasing risk of perforation caused by delay in surgical intervention.
急性阑尾炎是妊娠期手术干预最常见的非产科指征,发生率为1/500 ~ 1/2000。由于与妊娠相关的解剖和生理变化,阑尾炎可能出现诊断困境,导致治疗延误,从而增加阑尾穿孔的风险。阑尾炎的许多常见症状是正常妊娠的常见特征,包括下腹痛、恶心、呕吐和白细胞增多。此外,扩大的妊娠子宫可使阑尾发生不同程度的移位,从而改变阑尾炎的典型症状模式。妊娠期的非特异性表现可能需要使用诊断成像来帮助准确诊断。然而,阑尾穿孔是最常见的手术导致胎儿丢失的原因,任何诊断辅助所需的时间必须与延迟手术干预导致的穿孔风险增加进行权衡。

It is estimated that 20% of women experience symptoms of depression during pregnancy and antidepressant medication is prescribed for between 2% and 8% of pregnant women depending on the country of report. In the UK antidepressant prescribing during pregnancy increased fourfold from 1992 to 2006, with Selective Serotonin Reuptake Inhibitors (SSRIs) most often chosen. SSRIs cross the human placenta, with fetal levels varying according to treatment type and are found in amniotic fluid. The significance of prenatal exposure to SSRIs and outcomes in terms of the physical health and the neurodevelopment of the infant and child remainunclear.Several prescribed medications are known to be human teratogens, causing increased prevalence of a range of physical and neurodevelopmental deficits in exposed infants. Research into infant outcomes following prenatal exposure is challenging. Ethical constraints do not permit the most rigorous design for investigation, i.e.randomized double-blind controlled studies. In addition, variations in drug type, timing of exposure, dose, duration of exposure, placental passage and genetic factors all require consideration alongside maternal and infant demographic influences (e.g. maternal illness, socioeconomic status). Furthermore, a specific outcome type may be associated with specific risk variables and require targeted investigation. Maternal depression itself, either directly or indirectly, has been reported to influence obstetric and neonatal outcomes. Although beyond the scope of this review, research often fails to consider fetal exposure to antidepressants. Maternal antenatal depression is an important predictor of postnatal depression which may alsoimpact on infant neurodevelopment. Understanding the risks of maternal depression and its treatment with regard to the development of the child is of paramount importance for clinical decision making.Serotonin is known to play a role in the development and physiology of the central nervous system, the gastrointestinal and the cardiovascular systems. In the fetal brain serotonin modulates different developmental processes including neurogenesis, apoptosis and axon branching and therefore alterations in the serotonin system may directly impact on later neuronal development. The role of serotonin in fetal development raises the possibility that SSRI exposure in utero may predispose to structural birth defects and poorer longer term outcomes, however, to date such a relationship is unclear.This review aims to bring together clinical research that examines the immediate and longer term physical and developmental risks to the child that may be associated with prenatal exposure to SSRIs. The article also examines the methodological issues that may contribute to conflicting findings.
据估计,20%的妇女在怀孕期间出现抑郁症状,2%至8%的孕妇服用抗抑郁药物,这取决于报告的国家。在英国,从1992年到2006年,怀孕期间抗抑郁药的处方增加了四倍,其中选择选择性血清素再摄取抑制剂(SSRIs)最为常见。SSRIs穿过人胎盘,胎儿水平根据治疗类型而变化,并在羊水中发现。产前暴露于SSRIs及其结果在婴儿和儿童的身体健康和神经发育方面的意义尚不清楚。已知几种处方药物是人类致畸物,导致接触这些药物的婴儿出现一系列身体和神经发育缺陷的发生率增加。对产前暴露后婴儿结果的研究具有挑战性。伦理约束不允许最严格的调查设计,即随机双盲对照研究。此外,药物类型、暴露时间、剂量、暴露持续时间、胎盘通道和遗传因素的变化,以及孕产妇和婴儿的人口影响(例如,孕产妇疾病、社会经济地位),都需要考虑。此外,特定的结果类型可能与特定的风险变量相关,需要有针对性的调查。据报道,产妇抑郁本身直接或间接地影响产科和新生儿结局。虽然超出了这篇综述的范围,但研究往往没有考虑到胎儿接触抗抑郁药。母亲产前抑郁是产后抑郁的重要预测因子,产后抑郁也可能影响婴儿的神经发育。了解母亲抑郁症的风险及其治疗与孩子的发展是至关重要的临床决策。众所周知,血清素在中枢神经系统、胃肠道和心血管系统的发育和生理中起着重要作用。在胎儿大脑中,5 -羟色胺调节不同的发育过程,包括神经发生、细胞凋亡和轴突分支,因此5 -羟色胺系统的改变可能直接影响后来的神经元发育。血清素在胎儿发育中的作用提高了在子宫内暴露于SSRI可能导致结构性出生缺陷和较差的长期结果的可能性,然而,迄今为止这种关系尚不清楚。本综述旨在汇集临床研究,检查可能与产前暴露于ssri类药物有关的儿童近期和长期的身体和发育风险。本文还探讨了可能导致相互矛盾的研究结果的方法问题。

The prevalence of neural tube defects (NTD) in Europe is around 9 per 10,000 births making it one of the most frequent congential anomalies affecting the central nervous system. NTD encompass all anomalies that are secondary to failure of closure of the neural tube. In this review, we will first summarize the embryology and some epidemiologic aspects related to NTDs. The review focuses on myelomeningocele (MMC), which is the most common distal closure defect. We will describe the secondary pathologic changes in the central and peripheral nervous system that appear later on in pregnancy and contribute to the condition's morbidity. The postnatal impact of MMC mainly depends on the upper level of the lesion. In Europe, the vast majority of parents with a fetus with prenatally diagnosed NTDs, including MMC, opt for termination of pregnancy, as they are apparently perceived as very debilitating conditions. Animal experiments have shown that prenatal surgery can reverse this sequence. This paved the way for clinical fetal surgery resulting in an apparent improvement in outcome. The results of a recent randomized trial confirmed better outcomes after fetal repair compared to postnatal repair; with follow up for 30 months. This should prompt fetal medicine specialists to reconsider their position towards this condition as well as its prenatal repair. The fetal surgery centre in Leuven did not have a clinical programme for fetal NTD repair until the publication of the MOMS trial. In order to offer this procedure safely and effectively, we allied to a high volume centre willing to share its expertise and assist us in the first procedures. Given the maternal side effects of current open fetal surgical techniques, we have intensified our research programmes to explore minimally invasive alternatives. Below we will describe how we are implementing this.
神经管缺陷(NTD)在欧洲的患病率约为每10,000名新生儿中有9名,使其成为影响中枢神经系统的最常见的先天性异常之一。NTD包括所有继发于神经管闭合失败的异常。在这篇综述中,我们将首先概述与热带病有关的胚胎学和一些流行病学方面。本文综述的重点是脊髓脊膜膨出(MMC),这是最常见的远端闭合缺陷。我们将描述继发性病理变化在中枢和周围神经系统,出现在怀孕后期,并有助于条件的发病率。MMC的产后影响主要取决于病变的上部。在欧洲,绝大多数患有产前诊断的被忽视热带病(包括MMC)的胎儿的父母选择终止妊娠,因为他们显然被认为是非常虚弱的状况。动物实验表明,产前手术可以逆转这一顺序。这为临床胎儿手术铺平了道路,结果明显改善。最近的一项随机试验结果证实,与产后修复相比,胎儿修复后的结果更好;随访30个月。这应该促使胎儿医学专家重新考虑他们对这种情况以及产前修复的立场。鲁汶的胎儿外科中心在mom试验发表之前没有胎儿NTD修复的临床方案。为了安全有效地提供这一程序,我们与一个愿意分享其专业知识并协助我们进行第一次程序的大容量中心结盟。鉴于目前开放胎儿手术技术对母体的副作用,我们已经加强了我们的研究计划,以探索微创替代方案。下面我们将描述如何实现它。

FOLATE METABOLISM AND PREECLAMPSIA 叶酸代谢和子痫前期

Preeclampsia (PE) is a multisystem disorder of human pregnancy, affecting about 6% of all pregnancies worldwide, and is one of the leading causes of maternal and infant morbidity and mortality. Despite decades of research into the pathogenesis of this complex disease, the underlying mechanisms remain unclear. As a result, the options for prevention and management of PE are limited. In recent years, there has been a growing body of evidence suggesting that folate deficiency is associated with PE, and folic acid supplementation may reduce the risk of developing PE in certain populations. Folate contributes to cell division and growth, and folate metabolism is involved in a large number of physiological and pathophysiological processes in human development. Sufficient supply of folate is therefore particularly important during pregnancy. Nevertheless, the exact mechanisms of folic acid deficiency increasing the risk of developing PE are still unclear. This article reviews what is understood about the aetiology of PE and the relationship between folate metabolism and PE so as to enhance further discussions on the subject.
先兆子痫(PE)是一种人类妊娠多系统疾病,影响全球约6%的妊娠,是孕产妇和婴儿发病率和死亡率的主要原因之一。尽管对这种复杂疾病的发病机制进行了数十年的研究,但其潜在机制仍不清楚。因此,预防和管理PE的选择是有限的。近年来,越来越多的证据表明叶酸缺乏与PE有关,补充叶酸可以降低某些人群发生PE的风险。叶酸有助于细胞的分裂和生长,叶酸的代谢参与了人体发育过程中大量的生理和病理生理过程。因此,在怀孕期间补充充足的叶酸尤为重要。然而,叶酸缺乏增加PE发病风险的确切机制尚不清楚。本文综述了PE的病因学以及叶酸代谢与PE之间的关系,以促进对这一主题的进一步讨论。

Neonatal outcomes following late preterm birth 晚期早产后的新生儿结局
Pub Date : 2012-05-01 DOI: 10.1017/S0965539512000071
E. Boyle
It is well recognised that birth before 32 weeks of gestation is associated with substantial neonatal morbidity and mortality and these risks have been extensively reported. The focus of perinatal research for many years has therefore been very preterm and extremely preterm delivery, since the likelihood and severity of adverse neonatal outcomes are highest within this group. In contrast, until recently, more mature preterm infants have been understudied and indeed, almost ignored by researchers.
众所周知,在妊娠32周之前出生与大量新生儿发病率和死亡率有关,这些风险已被广泛报道。因此,多年来围产期研究的重点一直是极早产儿和极早产儿,因为在这一群体中,新生儿不良结局的可能性和严重程度最高。相比之下,直到最近,更成熟的早产儿还没有得到充分的研究,事实上,几乎被研究人员忽视了。

Hypoxia in pregnancy is rare, however the anatomical and physiological changes associated with pregnancy may exacerbate hypoxia and hypoxaemia arising from pathological processes. In this review we seek to briefly outline the well recognised changes to the maternal airway and respiratory anatomy and physiology. We will discuss a hierarchical approach to the tests used in differential diagnoses, summarise the physical principles behind commonly used tests and identify pitfalls and considerations in their use in the obstetric population. Some of the more commonly seen pathological states that may cause hypoxia in pregnancy will be discussed.
妊娠缺氧是罕见的,但与妊娠相关的解剖和生理变化可能加剧病理过程中产生的缺氧和低氧血症。在这篇综述中,我们试图简要概述公认的变化,产妇气道和呼吸解剖和生理。我们将讨论鉴别诊断中使用的分级检测方法,总结常用检测方法背后的物理原理,并确定在产科人群中使用检测方法时存在的缺陷和注意事项。一些更常见的病理状态,可能会导致缺氧在怀孕将讨论。

Umbilical cord prolapse is the descent of the umbilical cord through the cervix alongside (occult) or past (overt) the presenting part in the presence of ruptured membranes. Cord prolapse is a rare obstetric complication, usually requiring immediate delivery of the fetus to reduce neonatal morbidity and mortality. Therefore staff caring for women in labour should train regularly to manage it appropriately, because team training has been demonstrated to improve outcomes.
脐带脱垂是指在膜破裂的情况下,脐带沿呈现部(隐性)或经过呈现部(显性)而下降至子宫颈。脐带脱垂是一种罕见的产科并发症,通常需要立即分娩以降低新生儿的发病率和死亡率。因此,照顾临产妇女的工作人员应该定期进行培训,以便适当地进行管理,因为团队培训已被证明可以改善结果。

KIELLAND'S FORCEPS: PAST, PRESENT AND FUTURE Kielland钳:过去,现在和未来
Pub Date : 2012-02-01 DOI: 10.1017/S0965539512000022

Kielland's forceps have been in obstetric practice for over 80 years but their use causes a wide spectrum of reactions in obstetricians. Those that have been well tutored in their use argue that they are a very effective instrument to achieve vaginal delivery in the malpositioned fetus, avoiding the problems of full cervical dilation caesarean section, with low complications in their hands. These exponents of the instrument argue that the “art” of obstetrics is demonstrated in the use of Kielland's forceps. However, others claim that Kielland's forceps are dangerous with high complication rates and that they should be confined to the obstetric museum. This paper reviews the history of the instrument and its inventor, to consider evidence for its effectiveness and its safety, to briefly consider other methods for delivery of the malpositioned fetus at full cervical dilation and finally to complete the journey by considering the future with particular emphasis on training the new generation of obstetricians.
Kielland的产钳已经在产科实践超过80年,但他们的使用引起了广泛的反应在产科医生。那些在使用上受过良好指导的人认为,这是一种非常有效的工具,可以在位置不正确的胎儿中实现阴道分娩,避免了全宫颈扩张剖腹产的问题,而且并发症在他们手中很低。这些仪器的倡导者认为,“艺术”的产科是在使用Kielland的钳展示。然而,其他人声称Kielland的产钳是危险的,并发症率高,它们应该被限制在产科博物馆。本文回顾了该器械的历史及其发明者,考虑其有效性和安全性的证据,简要介绍了在宫颈完全扩张时分娩错位胎儿的其他方法,最后通过考虑未来特别强调培训新一代产科医生来完成这一旅程。
