    背景:非输卵管异位妊娠占所有异位妊娠的<10%。由于其稀有性和临床实践中的广泛差异,它的管理没有指导方针或共识。我们报告了我们在三级医院管理非输卵管异位妊娠20年的经验。
    方法:这是对2003年1月至2022年12月在三级医院住院的所有非输卵管异位妊娠妇女的回顾性研究。包括通过超声或手术诊断的非输卵管异位妊娠妇女进行分析。
    结果:在研究期间,180名妇女被诊断为非输卵管异位妊娠,平均妊娠6.8周。16.7%(30/180)通过辅助生殖受孕。医疗是81名妇女的一线管理选择,其中75例(92.1%)女性在经阴道超声引导下接受甲氨蝶呤病灶内给药.甲氨蝶呤病灶内的成功率为76.5%至92.3%。即使在胎儿搏动阳性或人绒毛膜促性腺激素水平高达252605U/L的情况下,甲氨蝶呤也能成功感染。27名妇女接受了预期治疗,40名妇女接受了手术。九(11.1%),两个(6.1%),一名(2.3%)妇女因医疗后大量或复发性出血而需要手术,期待,或手术治疗。子宫切开术和子宫动脉栓塞术对于控制一个剖宫产瘢痕和一个宫颈妊娠的出血是必要的。
    结论:局部甲氨蝶呤比全身甲氨蝶呤更有效,应考虑作为非输卵管异位妊娠的一线药物治疗。即使存在胎儿搏动或人绒毛膜促性腺激素水平较高,它在未破裂的非输卵管异位妊娠的治疗中也具有很高的成功率。但患者可能需要长时间的监测。由于术后腹腔内大量出血的风险,需要密切监测和随时可用的手术。
    BACKGROUND: Non-tubal ectopic pregnancies account for < 10% of all ectopic pregnancies. Due to its rarity and wide variation in clinical practice, there is no guideline or consensus for its management. We reported our 20-year experience in the management of non-tubal ectopic pregnancies in a tertiary hospital.
    METHODS: This is a retrospective review of all women admitted for non-tubal ectopic pregnancies from January 2003 to December 2022 in a tertiary hospital. Women with non-tubal ectopic pregnancies diagnosed by ultrasound or operation were included for analysis.
    RESULTS: Within the study period, 180 women were diagnosed to have non-tubal ectopic pregnancies at a mean gestation of 6.8 weeks. 16.7% (30/180) were conceived via assisted reproduction. Medical treatment was the first-line management option for 81 women, of which 75 (92.1%) women received intralesional methotrexate administered under transvaginal ultrasound guidance. The success rate of intralesional methotrexate ranges from 76.5% to 92.3%. Intralesional methotrexate was successful even in cases with a positive fetal pulsation or with high human chorionic gonadotrophin levels up to 252605U/L. Twenty seven women were managed expectantly and 40 underwent surgery. Nine (11.1%), two (6.1%), and one (2.3%) women required surgery due to massive or recurrent bleeding following medical, expectant, or surgical treatment. Hysterotomy and uterine artery embolization were necessary to control bleeding in one Caesarean scar and one cervical pregnancy.
    CONCLUSIONS: Intralesional methotrexate is more effective than systemic methotrexate and should be considered as first line medical treatment for non-tubal ectopic pregnancies. It has a high success rate in the management of unruptured non-tubal ectopic pregnancies even in the presence of fetal pulsations or high human chorionic gonadotrophin levels, but patients may require a prolonged period of monitoring. Close surveillance and readily available surgery were required due to the risk of heavy post-procedural intra-abdominal bleeding.

  • 文章类型: Case Reports
    我们描述了在体外受精(IVF)后患有轻度子宫内膜异位症和Allen-Masters综合征的女性的情况,在妊娠7周2天时出现腹痛。经阴道超声检查显示,右卵巢附近有一个妊娠囊,胎儿无法存活。由于腹痛加剧,进行了腹腔镜检查,发现右子宫骶韧带(USL)和道格拉斯袋中的血液破裂了异位妊娠。沿USL的腹膜切口有助于引流和去除异位妊娠。病理研究描述了子宫内膜组织的存在,与受孕产物直接相邻,这表明腹膜后植入可能是由于子宫内膜异位病变的存在而促进的。该病例强调了非常规异位妊娠的独特临床轨迹,提供了对异位植入的病理生理机制的新见解,并强调了在IVF和随后的妊娠期间对患者进行全面评估在确保有效治疗中的关键作用。
    We describe the case of a woman with mild endometriosis and Allen-Masters syndrome after in vitro fertilisation (IVF), presenting at 7 weeks 2 days gestation with abdominal pain. A transvaginal ultrasound revealed a gestational sac with a non-viable fetus near the right ovary. Laparoscopy was performed due to escalating abdominal pain which revealed a ruptured ectopic pregnancy at the right uterosacral ligament (USL) and blood in the pouch of Douglas. A peritoneal incision along the USL facilitated drainage and removal of the ectopic pregnancy. A pathological investigation described the presence of endometrial tissue directly adjacent to products of conception, which suggested a retroperitoneal implantation that may have been facilitated by the presence of an endometriotic lesion. This case underscores the distinctive clinical trajectory of unconventional ectopic pregnancies, provides novel insights into the pathophysiological mechanism of ectopic implantation and underscores the crucial role of comprehensive patient assessment during IVF and subsequent pregnancy in ensuring effective management.

    目的:沙眼衣原体(衣原体)是全球报道最多的细菌性性传播感染(STI)之一。衣原体可引起长期并发症,如盆腔炎(PID),异位妊娠(EP)和输卵管因素不孕症(TFI)。改变测试策略,例如减少无症状测试,影响衣原体监测,强调需要探索监测衣原体的替代方法。我们调查了对衣原体相关的长期并发症进行常规监测的可能性。
    方法:一项定性研究,包括对有目的的妇科医生样本进行15次深入访谈,全科医生(GP),2021-2022年在荷兰开展了性健康和急诊医生。半结构化访谈指南,重点介绍PID的诊断和注册经验,EP和TFI以及无症状衣原体检测策略的变化可能会对此产生影响。使用专题方法对访谈进行转录和分析。
    结果:分析表明,妇科医生最常报告诊断PID,EP和TFI。其他职业很少诊断这些并发症,急诊医生只诊断EP。大多数受访者报告了PID和EP的唯一注册码,但是TFI的编码更加模糊。它们反映了PID的诊断和注册,EP和TFI在其职业中的处理方式不同。大多数受访者承认在诊断代码中注册是一种有用的监视工具。他们对代表性(例如诊断标准解释的差异)和监测数据质量表示担忧。
    结论:在荷兰,妇科医生的患者档案对于监测衣原体相关长期并发症的诊断趋势可能是最完整的。然而,当建立衣原体并发症监测系统时,专业人员应参与进一步规范诊断和注册实践。这将提高并发症监测的质量和可解释性,并促进国家之间的比较。
    OBJECTIVE: Chlamydia trachomatis (chlamydia) is one of the most reported bacterial sexually transmitted infections (STI) worldwide. Chlamydia can cause long term complications such as pelvic inflammatory disease (PID), ectopic pregnancy (EP) and tubal factor infertility (TFI). Changing testing strategies, for example reduced asymptomatic testing, influence chlamydia surveillance, highlighting the need for exploring alternative ways of monitoring chlamydia. We investigated the possibility of introducing routine surveillance of chlamydia related long term complications.
    METHODS: A qualitative study including 15 in-depth interviews with a purposive sample of gynaecologists, general practitioners (GP), sexual health and emergency doctors was conducted in the Netherlands in 2021-2022. A semi-structured interview guide focused on experiences with diagnosis and registration of PID, EP and TFI and how a change in asymptomatic chlamydia testing strategy might influence this. Interviews were transcribed and analysed using a thematic approach.
    RESULTS: Analysis showed that gynaecologists most frequently reported diagnosing PID, EP and TFI. Other professions rarely diagnose these complications, with emergency doctors only diagnosing EP. Most respondents reported unique registration codes for PID and EP, but the coding for TFI is more ambiguous. They reflected that diagnosis and registration of PID, EP and TFI are handled differently within their professions. Most respondents acknowledged registration in diagnostic codes as a useful surveillance tool. They expressed concerns in representativeness (e.g. differences in interpretation of diagnosis criteria) and data quality for surveillance.
    CONCLUSIONS: Patient files of gynaecologists are likely to be most complete for monitoring trends of diagnosed chlamydia related long term complications in the Netherlands. However, when establishing a chlamydia complication surveillance system, professionals should be engaged in further standardizing diagnosis and registration practices. This will improve the quality and interpretability of complication surveillance and facilitate comparison between countries.

    目的:人工流产与异位妊娠之间关系的现有证据尚未得到严格评估。本系统综述提供了一个全面的评估,以检查人工流产(IA)是否可以增加异位妊娠(EP)的发生率。
    方法:我们搜索了PubMed,EMBASE,WebofScience,科克伦,CNKI,万方,和Sinomed数据库自成立以来一直持续到2023年2月。资格标准包括病例对照研究和分析与异位妊娠相关的人工流产的队列研究。使用R-studio版本1.1.383软件进行数据分析。
    结果:共纳入33项病例对照研究和7项队列研究,涉及132,926名参与者。在病例对照研究中,单因素分析数据显示,人工流产与异位妊娠之间存在显著关联(OR=2.32,95%CI=1.81~2.98).按地区亚组分析显示,美洲(OR=1.15,95%CI=0.92-1.43)和东地中海(OR=3.64,95%CI=0.88-15.18)无统计学意义。通过多元回归分析数据,该关系具有统计学意义(OR=1.97,95%CI=1.38-2.80)。在队列研究中,在敏感性分析中省略一项研究后发现有统计学意义(OR=1.42,95%CI=1.001-2.018).两种研究的综合结果表明,人工流产会在一定程度上增加异位妊娠的风险,但是结论需要谨慎考虑。
    结论:这项研究表明,IA可在一定程度上增加EP的风险,IA时间对风险有负面影响。安全流产和避免因意外怀孕而重复流产可以保护妇女的生育能力。
    OBJECTIVE: Existing evidence of the relationship between induced abortion and ectopic pregnancy has not been assessed rigorously. This systematic review provides a comprehensive evaluation to examine whether induced abortion (IA) can increase the rate of ectopic pregnancy (EP).
    METHODS: We searched PubMed, EMBASE, Web of Science, Cochrane, CNKI, WanFang, and Sinomed databases since their inception until February 2023. Eligibility criteria included case-control studies and cohort studies that analyzed induced abortion associated with ectopic pregnancy. Data analyses were conducted by using R-studio Version 1.1.383 software.
    RESULTS: A total of 33 case-control studies and 7 cohort studies involving 132,926 participants were included. In case-control studies, there was a significant association between induced abortion and ectopic pregnancy by using single-factor analysis data (OR = 2.32, 95% CI = 1.81-2.98). Subgroup analysis by region suggested no statistical significance in the Americas (OR = 1.15, 95% CI = 0.92-1.43) and Eastern Mediterranean (OR = 3.64, 95% CI = 0.88-15.18). The relationship was significant by using multiple regression analysis data (OR = 1.97, 95% CI = 1.38-2.80). In cohort studies, statistical significance was found (OR = 1.42, 95% CI = 1.001-2.018) after omitting one study in sensitivity analysis. The combined results of the two types of studies suggested that induced abortion would increase the risk of ectopic pregnancy to some degree, but the conclusion needs to be considered with caution.
    CONCLUSIONS: This study indicated that IA could increase the risk of EP to some degree and the times of IA had a negative impact on the risk. Safe abortion and avoiding repeat abortion due to unintended pregnancy could protect women\'s fertility.

    剖宫产(CS)分娩率在国际上有所上升,在一些国家达到50%。由于存在出血风险,在先前的子宫切开术部位异常植入新妊娠是重要的并发症,子宫破裂,和进展为胎盘植入谱(PAS),一种高发病率的疾病,有可能发生灾难性的产科出血,孕产妇和胎儿死亡率,和生育能力的丧失。剖宫产瘢痕异位妊娠(CSEP)是描述这些妊娠的推荐术语,根据囊植入部位识别,增长模式,和相关的异常灌注。CSEP的真实发生率尚不清楚,因为该疾病可能未被诊断和报告。2022年母胎医学协会咨询系列指出,严重的孕产妇发病率和死亡率与诊断CSEP的困难有关。作者回顾了CSEP的影像学征象,一些可能导致延误或漏诊的陷阱,及其后果。CSEP必须与正常妊娠的低植入区分开来,宫颈异位妊娠,和不断发展的怀孕损失。早期识别允许及时和安全的治疗,通常是手术。早期治疗可降低医疗费用,住院时间缩短,保存生育力,和预防医源性早产,这在进展到PAS的情况下是典型的。子宫切除术对育龄期患者有严重的负面心理后果;CSEP的早期诊断和及时治疗可以预防这种常被忽视的并发症。©RSNA,2024补充材料可用于本文。
    The rate of cesarean section (CS) for delivery has increased internationally, reaching 50% in some countries. Abnormal implantation of a new pregnancy at the site of the prior hysterotomy is an important complication because of the risks of hemorrhage, uterine rupture, and progression to placenta accreta spectrum (PAS), a condition with high morbidity with potential for catastrophic obstetric hemorrhage, maternal and fetal mortality, and loss of fertility. Cesarean scar ectopic pregnancy (CSEP) is the recommended term to describe these pregnancies, which are recognized on the basis of the sac implantation site, growth pattern, and associated abnormal perfusion. The true incidence of CSEP is unknown because the condition is likely underdiagnosed and underreported. The 2022 Society for Maternal-Fetal Medicine consult series notes that severe maternal morbidity and mortality are linked to difficulty in making the diagnosis of CSEP. The authors review the signs of CSEP at imaging, some pitfalls that may lead to delayed or missed diagnosis, and the consequences thereof. CSEPs must be differentiated from low implantation of a normal pregnancy, cervical ectopic pregnancy, and evolving pregnancy loss. Early recognition allows prompt and safe treatment that is usually surgical. Early treatment results in decreased health care costs, a shorter hospital stay, preservation of fertility, and prevention of iatrogenic preterm delivery, which is typical in cases that progress to PAS. Hysterectomy has serious negative psychologic consequences for patients of childbearing age; early diagnosis and prompt treatment of CSEP can prevent this often-ignored complication. ©RSNA, 2024 Supplemental material is available for this article.

    异位妊娠是妊娠头三个月发病和死亡的重要原因。需要特定的β-人绒毛膜促性腺激素(β-hCG)水平才能符合诊断测试(盆腔超声)的医院协议可能会延迟诊断和治疗。在这项研究中,我们试图确定β-hCG水平与异位妊娠大小之间的关系以及相关结局。
    我们在一个城市,专门从事产科护理的学术急诊科,从2015年1月1日-2017年12月31日。提取的变量包括演示文稿,治疗,不良结果,和破裂率。
    我们确定了519例独特的异位妊娠。在那些宫外孕中,22.9%的人在超声波上有破裂的证据,14.4%的患者在就诊时表现出血流动力学不稳定的证据(脉搏>100次/分钟;收缩压<90mmHg;或明显失血的证据)。医疗管理结果如下:177例接受单剂量甲氨蝶呤的患者,14.7%的医疗管理失败,需要手术干预;在接受多剂量甲氨蝶呤的46人中,36.9%的医疗管理失败,需要手术干预。最终,55.7%的患者需要对其异位妊娠进行手术治疗。初始表现时的平均β-hCG水平为每毫升7,096毫国际单位(mIU/mL)(SD88,872mIU/mL),中位数为1,289mIU/mL;50.4%的异位妊娠患者的β-hCG水平低于1,500mIU/mL的标准歧视区。此外,有破裂证据的患者中有44%的β-hCG水平低于1,500mIU/mL。异位妊娠的大小(基于最大尺寸,以毫米为单位)与β-hCG水平的比较显示出非常弱的相关性(r=0.144,P<.001),超声检测异位妊娠与β-hCG水平无关。
    β-hCG水平与异位妊娠的存在或大小无关。在临床怀疑异位妊娠的患者中,无论β-hCG水平如何,都需要进行诊断性影像学检查。几乎六分之一的患者有血流动力学不稳定的证据,大约四分之一的患者出现破裂的证据,需要紧急手术治疗。最终,超过一半的患者需要手术程序来明确治疗异位妊娠.
    UNASSIGNED: Ectopic pregnancies are a significant cause of morbidity and mortality in the first trimester of pregnancy. Hospital protocols requiring a specific beta-human chorionic gonadotropin (β-hCG) level to qualify for diagnostic testing (pelvic ultrasound) can delay diagnosis and treatment. In this study we sought to determine the relationship between β-hCG level and the size of ectopic pregnancy with associated outcomes.
    UNASSIGNED: We performed a retrospective case review of patients diagnosed with ectopic pregnancy in an urban, academic emergency department specializing in obstetrical care, from January 1, 2015-December 31, 2017. Variables extracted included presentation, treatment, adverse outcomes, and rates of rupture.
    UNASSIGNED: We identified 519 unique ectopic pregnancies. Of those ectopic pregnancies, 22.9% presented with evidence of rupture on ultrasound, and 14.4% showed evidence of hemodynamic instability (pulse >100 beats per minute; systolic blood pressure <90 millimeters of mercury; or evidence of significant blood loss) on presentation. Medical management outcomes were as follows: of 177 patients who received single-dose methotrexate, 14.7% failed medical management and required surgical intervention; of 46 who received multi-dose methotrexate, 36.9% failed medical management and required surgical intervention. Ultimately, 55.7% of patients required operative management of their ectopic pregnancy. Mean β-hCG level at initial presentation was 7,096 milli-international units per milliliter (mIU/mL) (SD 88,872 mIU/mL) with a median of 1,289 mIU/mL; 50.4% of ectopic pregnancies presented with β-hCG levels less than the standard discriminatory zone of 1,500 mIU/mL. Additionally, 44% of the patients who presented with evidence of rupture had β-hCG levels less than 1,500 mIU/mL. Comparison of size of ectopic pregnancy (based on maximum dimension in millimeters) to β-hCG levels revealed a very weak correlation (r = 0.144, P < .001), and detection of ectopic pregnancies by ultrasound was independent of β-hCG levels.
    UNASSIGNED: Levels of β-hCG do not correlate with the presence or size of an ectopic pregnancy, indicating need for diagnostic imaging regardless of β-hCG level in patients with clinical suspicion for ectopic pregnancy. Almost one-sixth of patients presented with evidence of hemodynamic instability, and approximately one quarter of patients presented with evidence of rupture requiring emergent operative management. Ultimately, more than half of patients required an operative procedure to definitively manage their ectopic pregnancy.

    目的:使用不同的甲氨蝶呤(MTX)方案治疗异位妊娠已经确立。本研究旨在评估单剂量和双剂量MTX方案治疗不明部位妊娠(PUL)的疗效。
    方法:这项回顾性研究是在妇科内分泌科进行的,大学医院,克拉科夫,波兰。2014年1月至2023年9月,血液动力学稳定的PUL女性入组。人口统计,比较单剂量MTX组和双剂量MTX组妇女的孕龄和治疗结局。主要结果是成功率,以未经手术干预治疗的妇女人数来衡量。次要结果是达到β-人绒毛膜促性腺激素(β-hCG)适当降低所需的MTX天数。
    结果:研究中纳入了211名妇女(平均年龄33±1.8岁),总体成功率为89.1%。发现单剂量和双剂量MTX方案具有可比的治疗成功率(93%和95%,分别)。与初始血清β-hCG较高的女性相比,初始血清β-hCG较低(<2000mIU/ml)的女性具有更高的治疗效果(96.5%vs71.4%)。无论协议类型如何。与使用双剂量MTX方案治疗的妇女相比,使用单剂量MTX方案治疗的妇女的住院时间缩短了1天。
    结论:单剂量和双剂量MTX方案具有相当的疗效和安全性,在初始β-hCG<2000mIU/ml的PUL女性中,应同样考虑。
    OBJECTIVE: The use of various methotrexate (MTX) protocols for the treatment of ectopic pregnancy is well established. This study aimed to evaluate the efficacy of single- and double-dose MTX protocols for the treatment of pregnancy of unknown location (PUL).
    METHODS: This retrospective study was conducted in the Department of Gynaecological Endocrinology, University Hospital, Krakow, Poland. Haemodynamically stable women with PUL were enrolled between January 2014 and September 2023. Demographics, gestational age and treatment outcomes were compared between women in the single-dose MTX group and women in the double-dose MTX group. The primary outcome was the success rate, measured as the number of women treated without surgical intervention. The secondary outcome was the number of days of MTX needed to achieve an appropriate decrease in beta-human chorionic gonadotrophin (β-hCG).
    RESULTS: Two hundred and eleven women (mean age 33 ± 1.8 years) with PUL were enrolled in the study, with an overall success rate of 89.1 %. Single- and double-dose MTX protocols were found to have comparable treatment success rates (93 % and 95 %, respectively). Women with lower initial serum β-hCG (<2000 mIU/ml) had higher treatment efficacy compared with women with higher initial serum β-hCG (96.5 % vs 71.4 %), regardless of protocol type. The length of hospital stay for the women treated with the single-dose MTX protocol was 1 day shorter compared with that for the women treated with the double-dose MTX protocol.
    CONCLUSIONS: Single- and double-dose MTX protocols have comparable efficacy and safety, and should be equally considered in women with PUL with initial β-hCG < 2000 mIU/ml.

    在前三个月,大量的妊娠丢失,1-2%是异位妊娠(EP)。早期妊娠丢失通常会导致大量出血或感染,而EP是孕早期孕产妇死亡的主要原因。妊娠丢失和EP的症状非常相似(包括疼痛和出血);然而,这些症状在常住妊娠(LNSP)中也很常见.迄今为止,尚未发现生物标志物来区分LNSP与妊娠早期后不会进展的妊娠(非存活或EP),一起定义为合并不良结局(CAO)。在这项研究中,我们提出了一种新的机器学习流程来创建预测模型,该模型可识别复合生物标志物,从而在有症状的女性中区分LNSP和CAO.这项前瞻性队列研究包括370名参与者。在最终临床诊断妊娠结局之前,从首次急诊就诊的参与者中前瞻性地收集单个血液样本:LNSP,流产,不明位置妊娠(PUL)或输卵管EP(tEP)。流产,将PUL和tEP归为CAO组。在血浆中测量人绒毛膜促性腺激素β(β-hCG)和孕酮浓度。对血清样品进行非靶向代谢组学分析。队列随机分为训练和验证数据集,列车数据集进行变量选择。9种代谢物信号被鉴定为LNSP与CAO的关键鉴别器。随机森林模型仅使用稳定的代谢物信号构建,或与血浆激素浓度和人口统计数据相结合。将LNSP与CAO进行比较时,具有稳定代谢物信号的模型仅表现出适度的预测准确性(0.68),这与β-hCG和孕酮的模型相当(0.71)。用于LNSP预测的最佳模型包括稳定的代谢物信号和激素浓度(准确度=0.79)。总之,来自单个血液样本的血清代谢物水平和生化标志物在区分LNSP和CAO妊娠时具有适度的预测效用,这是通过使用机器学习的变量选择和组合来改进的。在紧急情况下,进行诊断测试以确认LNSP,从而排除影响孕产妇发病率和潜在威胁生命的结局的怀孕将是无价的。
    A significant number of pregnancies are lost in the first trimester and 1-2% are ectopic pregnancies (EPs). Early pregnancy loss in general can cause significant morbidity with bleeding or infection, while EPs are the leading cause of maternal mortality in the first trimester. Symptoms of pregnancy loss and EP are very similar (including pain and bleeding); however, these symptoms are also common in live normally sited pregnancies (LNSP). To date, no biomarkers have been identified to differentiate LNSP from pregnancies that will not progress beyond early gestation (non-viable or EPs), defined together as combined adverse outcomes (CAO). In this study, we present a novel machine learning pipeline to create prediction models that identify a composite biomarker to differentiate LNSP from CAO in symptomatic women. This prospective cohort study included 370 participants. A single blood sample was prospectively collected from participants on first emergency presentation prior to final clinical diagnosis of pregnancy outcome: LNSP, miscarriage, pregnancy of unknown location (PUL) or tubal EP (tEP). Miscarriage, PUL and tEP were grouped together into a CAO group. Human chorionic gonadotrophin β (β-hCG) and progesterone concentrations were measured in plasma. Serum samples were subjected to untargeted metabolomic profiling. The cohort was randomly split into train and validation data sets, with the train data set subjected to variable selection. Nine metabolite signals were identified as key discriminators of LNSP versus CAO. Random forest models were constructed using stable metabolite signals alone, or in combination with plasma hormone concentrations and demographic data. When comparing LNSP with CAO, a model with stable metabolite signals only demonstrated a modest predictive accuracy (0.68), which was comparable to a model of β-hCG and progesterone (0.71). The best model for LNSP prediction comprised stable metabolite signals and hormone concentrations (accuracy = 0.79). In conclusion, serum metabolite levels and biochemical markers from a single blood sample possess modest predictive utility in differentiating LNSP from CAO pregnancies upon first presentation, which is improved by variable selection and combination using machine learning. A diagnostic test to confirm LNSP and thus exclude pregnancies affecting maternal morbidity and potentially life-threatening outcomes would be invaluable in emergency situations.
