Introduction

Robot-assisted obstetric ultrasound is a method where the obstetrician in the hospital can control an ultrasound probe and assess biometric measurements and biophysical observations of a fetus, at a remote location. This two-aimed study evaluates the diagnostic accuracy of robot-assisted ultrasound compared to traditional ultrasound and explores patient experiences.

Material and Methods

Forty-six middle-risk pregnant women in 2nd and 3rd trimester were recruited. Thirty women were recruited for an intra observer study to compare the quality of the robot-assisted obstetrical ultrasound and traditional obstetric ultrasound. Fifteen traditional ultrasound examinations and 15 robotic-assisted ultrasound examinations were performed and head circumference (HC), biparietal diameter (BPD), abdominal circumference (AC), femur length (FL), amniotic fluid index (AFI), Doppler in the umbilical arteria, and biophysical observations of the fetus were registered. Another 16 women were recruited to a mixed design study aiming to explore the women's experiences with the robot-assisted ultrasound method. These women completed a questionnaire of 20 questions about patient experience, using a 5-point Likert scale. Two of them also participated in qualitative interviews to provide deeper insights.

Results

Biometric measurements showed excellent reliability (intraclass correlation coefficient 0.990–0.993) with acceptable limits of agreement. Twenty questions about patient experiences were asked and 94% of the women scored for highest level of satisfaction. Interviews revealed the value of avoiding long-distance travel when image quality and digital communication experiences are good.

Conclusions

Robot-assisted obstetric ultrasound is a reliable alternative to traditional ultrasound for middle-risk pregnancies in rural areas, offering high diagnostic accuracy and patient satisfaction. Most women would agree to a robotic ultrasound scan examination again. The patients' experiences are thus in line with the Norwegian governments' intention to use technology to secure equality in health care in rural areas.

机器人辅助的产科超声是一种方法,医院的产科医生可以控制超声探头,并在远程位置评估胎儿的生物特征测量和生物物理观察。本研究评估了机器人辅助超声与传统超声相比的诊断准确性,并探讨了患者的体验。材料与方法:选取妊娠2 ~ 3月的中危孕妇46例。30名妇女被招募参加一项内部观察研究,以比较机器人辅助的产科超声和传统产科超声的质量。进行15次传统超声检查和15次机器人辅助超声检查,记录胎儿头围(HC)、双顶径(BPD)、腹围(AC)、股骨长(FL)、羊水指数(AFI)、脐动脉多普勒和生物物理观察。另外16名女性被招募到一项混合设计研究中,旨在探索女性使用机器人辅助超声方法的体验。这些女性使用李克特5分制完成了一份关于患者体验的20个问题的调查问卷。其中两人还参加了定性访谈,以提供更深入的见解。结果:生物特征测量结果具有良好的信度(类内相关系数为0.990 ~ 0.993)和可接受的一致限。研究人员询问了20个关于患者体验的问题,94%的女性获得了最高的满意度。采访显示,当图像质量和数字通信体验良好时,避免长途旅行的价值。结论:机器人辅助产科超声可替代传统超声诊断农村中危妊娠,诊断准确率高,患者满意度高。大多数女性会同意再次进行机器人超声扫描检查。因此,患者的经历符合挪威政府利用技术确保农村地区医疗保健平等的意图。

Introduction: Endometriosis is a chronic and estrogen-dependent disorder that affects about 10% of women of reproductive age worldwide. Endometriosis has been associated with chronic inflammation and an atherogenic lipid profile, two conditions that increase the risk of atherothrombotic cardiovascular diseases.

Material and methods: A literature search for relevant studies published from the earliest record to 31 March 2025 was conducted in MEDLINE and EMBASE databases. The following MESH terms were searched: "stroke," "cerebrovascular disease," "cardiovascular disease," "coronary heart disease," "ischemic heart disease," "mortality," and "endometriosis." The results of each study were pooled, and an overall estimate of relative risk was obtained with a random-effect model. Homogeneity between studies was analyzed using I2 statistics. This review was not registered.

Results: Ten studies were eligible for inclusion in this meta-analysis. Five studies reported an increased risk of stroke with endometriosis, with a pooled risk of 1.18 (95% confidence intervals [95% CI] [1.13-1.22]). Four studies reported an increased risk of coronary heart disease with endometriosis, with a pooled risk of 1.36 (95% CI [1.32-1.40]). Four studies reported an increased risk of composite cardiovascular disease with endometriosis, with a pooled risk of 1.16 (95% CI [1.12-1.20]). Although the homogeneity is high in results, the confounding factors considered in the different studies vary. Thus, these results must be interpreted with caution.

Conclusions: Endometriosis is associated with an increased risk of cardiovascular disease. Further research is required to confirm these findings. However, these results highlight the importance of considering primary cardiovascular prevention strategies for women with endometriosis.

子宫内膜异位症是一种慢性雌激素依赖性疾病,影响全球约10%的育龄妇女。子宫内膜异位症与慢性炎症和动脉粥样硬化性脂质谱有关,这两种情况会增加动脉粥样硬化性血栓性心血管疾病的风险。材料和方法:在MEDLINE和EMBASE数据库中检索最早记录至2025年3月31日发表的相关研究。以下MESH术语被搜索:“中风”、“脑血管疾病”、“心血管疾病”、“冠心病”、“缺血性心脏病”、“死亡率”和“子宫内膜异位症”。将每项研究的结果汇总,并通过随机效应模型获得相对风险的总体估计。采用I2统计分析研究间的同质性。本综述未注册。结果:10项研究符合纳入本荟萃分析的条件。五项研究报告了子宫内膜异位症卒中的风险增加,合并风险为1.18(95%可信区间[95% CI][1.13-1.22])。四项研究报告了子宫内膜异位症并发冠心病的风险增加,合并风险为1.36 (95% CI[1.32-1.40])。四项研究报告了子宫内膜异位症合并复合心血管疾病的风险增加,合并风险为1.16 (95% CI[1.12-1.20])。虽然结果的同质性很高,但不同研究中考虑的混杂因素各不相同。因此,必须谨慎地解释这些结果。结论:子宫内膜异位症与心血管疾病的风险增加有关。需要进一步的研究来证实这些发现。然而,这些结果强调了考虑子宫内膜异位症妇女初级心血管预防策略的重要性。

As medical knowledge and technologies rapidly evolve, curricula have become increasingly dense, and designing effective OB-GYN education that prepares learners for diverse medical careers within limited timeframes is a global challenge. This review provides an international overview of contemporary medical education in obstetrics and gynecology (OB-GYN) across undergraduate, postgraduate, and continuing professional development levels. A narrative review of recent peer-reviewed literature, international guidelines, and global initiatives (2023–2025) was conducted, identifying key innovations, trends, and challenges in OB-GYN education worldwide, with a focus on curriculum reforms, competency-based education, simulation, telemedicine, AI applications, global standardization, and equity-oriented initiatives. Undergraduate OB-GYN curricula are increasingly standardized, integrating core competencies, early clinical exposure, and reproductive health. Postgraduate training adopts competency-based frameworks, enhanced by simulation, virtual reality, and tele-education, while continuing medical education has shifted toward flexible digital platforms and structured credentialing. Innovations, such as AI-driven learning tools, simulation drills, and telemedicine-based training, have improved skill acquisition, and global bodies, such as FIGO, RCOG, and ACOG, promote curriculum harmonization and equity. The COVID-19 pandemic accelerated digital adoption but revealed gaps in surgical training and support. Overall, OB-GYN education is in a transformative phase, marked by technology, standardization, and equity, yet significant disparities persist, especially in resource-limited settings. Continued global collaboration, investment in educational infrastructure, and adaptive curriculum development are essential to prepare OB-GYN professionals for evolving clinical demands and healthcare inequities in the postpandemic era.

随着医学知识和技术的迅速发展,课程变得越来越密集,设计有效的妇产科教育,使学习者在有限的时间内为不同的医学职业做好准备,是一项全球性的挑战。本文综述了当代妇产科医学教育的国际概况,包括本科、研究生和持续专业发展水平。对最近的同行评议文献、国际指南和全球倡议(2023-2025)进行了叙述回顾,确定了全球妇产科教育的关键创新、趋势和挑战,重点是课程改革、基于能力的教育、模拟、远程医疗、人工智能应用、全球标准化和面向公平的倡议。本科妇产科课程越来越标准化,整合了核心能力、早期临床接触和生殖健康。研究生培训采用以能力为基础的框架,辅以模拟、虚拟现实和远程教育,而继续医学教育则转向灵活的数字平台和结构化认证。人工智能驱动的学习工具、模拟演练和基于远程医疗的培训等创新改善了技能获取,FIGO、RCOG和ACOG等全球机构促进了课程的协调和公平。2019冠状病毒病大流行加速了数字化的采用,但暴露了外科培训和支持方面的差距。总体而言,妇产科教育正处于变革阶段,以技术、标准化和公平为标志,但显著的差距仍然存在,特别是在资源有限的环境中。持续的全球合作、对教育基础设施的投资和适应性课程的开发对于培养妇产科专业人员应对大流行后时代不断变化的临床需求和卫生保健不平等至关重要。

Introduction

Adequate treatment of cervical precancer, defined as negative margins and a negative HPV test post-treatment, is essential for cervical cancer prevention, as inadequate excision of cervical precancer and a positive HPV test are associated with increased risk of recurrence. Here, we aimed to describe trends in the proportion of women receiving adequate treatment in Denmark.

Material and Methods

Nationwide historical cohort study including Danish women ≥18 years treated with large loop excision of the transformation zone (LLETZ) from 2013 to 2022. Using the Danish Pathology Register, we collected information on all LLETZ procedures performed due to cervical intraepithelial neoplasia grade 1 or worse (CIN1+). We calculated the proportion of negative margins and negative HPV tests post-treatment, overall and stratified by histology, age, calendar time, and residing region. Results were mainly reported descriptively.

Results

We included 41 128 women (median age: 35 years, interquartile range: 28–44). A total of 20 744 (50.4%) had negative margins, with the lowest proportion in women with CIN3 (47.2%) or adenocarcinoma in situ (38.3%). The proportion of negative margins declined with increasing age, from 54.1% in women aged 18–29 years to 43.6% in women aged ≥50 years. Overall, 62.4% had a negative HPV test, with no major differences observed across histology groups. The proportion of negative HPV tests ranged from 62.8% to 66.9% in women aged 18–49, whereas it was lower in women aged ≥50 years (48.4%).

Conclusions

Women aged ≥50 years were less likely to have negative margins and a negative HPV test post-treatment compared to women aged 18–49. These findings prompt a need to optimize treatment in this group of women to reduce the risk of cervical cancer.

引言:充分治疗宫颈癌前病变(定义为边缘阴性和治疗后HPV检测阴性)对于预防宫颈癌至关重要,因为宫颈癌前病变切除不充分和HPV检测阳性与复发风险增加相关。在这里,我们的目的是描述丹麦接受适当治疗的妇女比例的趋势。材料和方法:2013年至2022年接受大环切除(LLETZ)治疗的≥18岁丹麦女性的全国历史队列研究。使用丹麦病理学记录,我们收集了所有因宫颈上皮内瘤变1级或更糟(CIN1+)而行LLETZ手术的信息。我们计算了治疗后阴性边缘和阴性HPV检测的比例,总体和按组织学、年龄、日历时间和居住地区分层。结果以描述性报道为主。结果:我们纳入了41 128名女性(中位年龄:35岁,四分位数范围:28-44岁)。共有20744例(50.4%)患者的切缘呈阴性,其中CIN3(47.2%)或原位腺癌(38.3%)患者的比例最低。阴性切缘的比例随着年龄的增长而下降,从18-29岁女性的54.1%下降到≥50岁女性的43.6%。总体而言,62.4%的人HPV检测呈阴性,在组织学组之间没有观察到重大差异。在18-49岁的女性中,HPV检测阴性的比例为62.8%至66.9%,而在≥50岁的女性中,这一比例较低(48.4%)。结论:与18-49岁的女性相比,≥50岁的女性在治疗后出现阴性边缘和HPV检测阴性的可能性更小。这些发现提示需要优化这组妇女的治疗,以降低宫颈癌的风险。

<div> <section> <h3> Introduction</h3> <p>The uterus exhibits dynamic peristaltic activity across the menstrual cycle, playing a critical role in reproductive processes such as sperm transport and embryo implantation. However, current imaging methods to assess this activity provide little information and are limited by subjectivity and lack of sensitivity. A recent pilot study has shown the potential of intracavitary electrohysterography (IC-EHG) to study peristalsis in the uterine fundus. This study aimed to generalize previous results, compare peristalsis in other uterine regions, and study more peristaltic features.</p> </section> <section> <h3> Material and Methods</h3> <p>This prospective multicenter cohort study included 40 healthy women with proven fertility. IC-EHG signals were recorded from different uterine sites for 30 min during three menstrual phases: mid-follicular (MF), early luteal (EL), and late luteal (LL) using a custom-designed multipolar catheter. Primary outcomes: contraction frequency (CT/min) and amplitude (μV); secondary outcomes: basal amplitude, contraction time percentage, contractility index and local organization index. Statistical comparisons between phases and regions were performed using Wilcoxon signed-rank tests.</p> </section> <section> <h3> Results</h3> <p>A total of 95 fundal and 90 lower-segment IC-EHG recordings were analyzed. Contraction frequency peaked during the EL phase (fundus: 3.91 CT/min; lower segment: 4.01 CT/min) and was lowest during MF (fundus: 3.28 CT/min, <i>p</i> = 0.042; lower segment: 3.65 CT/min, <i>p</i> = 0.024). Fundal contraction amplitude decreased progressively from MF (16.27 μV) to LL phase (10.56 μV, <i>p</i> < 0.001). Basal amplitude, contraction time percentage and contractility index were also lowest in the LL phase for both uterine regions. Except for frequency, fundus peristaltic activity features were smaller than those of the lower segment, significantly during the MF phase. Local coordination index revealed lower local cell organization in the fundus across all phases, with maximum coordination during EL in both regions (<i>p</i> < 0.01).</p> </section> <section> <h3> Conclusions</h3> <p>IC-EHG technique enables objective, reproducible, and quantitative assessment of multiple aspects of uterine peristalsis, revealing distinct regional and cycle-phase–dependent patterns.

子宫在整个月经周期中表现出动态蠕动活动,在精子运输和胚胎着床等生殖过程中起着关键作用。然而,目前评估这种活动的成像方法提供的信息很少,并且受主观性和缺乏敏感性的限制。最近的一项初步研究表明,腔内子宫电图(IC-EHG)研究子宫底蠕动的潜力。本研究旨在总结以往的研究结果,比较其他子宫区域的蠕动情况,并研究更多的蠕动特征。材料和方法:这项前瞻性多中心队列研究包括40名已证实生育能力的健康妇女。在卵泡中期(MF)、黄体早期(EL)和黄体晚期(LL)三个月经阶段,使用特制的多极导管记录不同子宫部位30分钟的IC-EHG信号。主要观察指标:收缩频率(CT/min)、收缩幅度(μV);次要观察指标:基础振幅、收缩时间百分比、收缩性指数、局部组织指数。阶段和区域之间的统计比较采用Wilcoxon符号秩检验。结果:共分析95个基底节段和90个下节段的IC-EHG记录。收缩频率在EL期最高(眼底:3.91 CT/min,下段:4.01 CT/min),在MF期最低(眼底:3.28 CT/min, p = 0.042,下段:3.65 CT/min, p = 0.024)。结论:IC-EHG技术能够客观、可重复、定量地评估子宫蠕动的多个方面,显示出明显的区域和周期相依赖性模式。在LL期大多数收缩特征的下降支持胚胎着床所需的生理子宫静止。子宫底在MF期更为活跃。本研究为健康、生育条件提供了参考价值,并可为进一步调查因疾病或干预策略而引起的改变提供信息。

Introduction: Further prolapse in the same or a different vaginal compartment is common, particularly following native tissue surgery. This study aims to report the rates of reoperations for prolapse and subjective recurrence after native tissue and mesh-augmented surgeries. Additionally, it seeks to describe the methods of repeat surgery for prolapse and to evaluate long-term mesh complications.

Material and methods: This is a follow-up study of the nationwide cohort (ClinicalTrials.gov [NCT02716506]) of pelvic organ prolapse surgeries performed in 2015 in Finland. Prolapse recurrence, reoperations and mesh complications were studied utilizing data from patient questionnaires and the national register. Reoperation rates, timing, methods of repeat surgery, and rates of subjective recurrence were compared among native tissue, transvaginal mesh and abdominal mesh surgeries. Predictive factors for reoperation were studied with logistic regression analysis. Mesh-related complications were evaluated after transvaginal and abdominal mesh repair.

Results: The mean follow-up of 3321 women was 7.4 years, during which 443 (13%) underwent reoperation for prolapse; 13.9% after native tissue, 10.1% after transvaginal mesh, and 12.1% after abdominal mesh repair (p = 0.09). Up to one third of women reported symptoms of vaginal bulging during follow-up, with significantly lower rates after transvaginal mesh surgery at 2- and 5-year follow-ups. The majority of reoperations for prolapse were single-site; anterior or apical repair was most common after native tissue and abdominal mesh surgery, while reoperations after transvaginal repair involved mainly posterior or apical compartments. Mesh was used in 40% of all reoperations. Prolapse surgery involving both posterior and apical compartments was the only factor associated with increased risk for reoperation (aOR 1.95 CI 1.30-2.92). Only 1.6% of women had a surgically treated mesh complication based on the register data, while the rates of patient-reported mesh exposures and mesh-related reoperations were 6.5% and 6.4%, with no significant difference between the two mesh groups.

Conclusions: The long-term risk of reoperation for prolapse was similar after native tissue and mesh-augmented surgery, while the site of reoperation differed based on the type of surgical treatment. Mesh complication rates were similar after transvaginal and abdominal mesh repair, and the majority of mesh exposures did not require surgical treatment.

简介:在同一或不同的阴道隔室进一步脱垂是常见的,特别是在原生组织手术后。本研究旨在报告脱垂的再手术率和自体组织和补片手术后的主观复发率。此外,它试图描述的方法重复手术脱垂和评估长期补片并发症。材料和方法:这是一项对2015年芬兰盆腔器官脱垂手术的全国队列(ClinicalTrials.gov [NCT02716506])的随访研究。利用患者问卷和国家登记的数据研究脱垂复发、再手术和补片并发症。比较自然组织补片、经阴道补片和腹部补片手术的再手术率、时间、重复手术方法和主观复发率。采用logistic回归分析对再手术的预测因素进行分析。经阴道和腹部补片修复后评估补片相关并发症。结果:3321例女性平均随访7.4年,其中443例(13%)因脱垂再次手术;经阴道补片术后13.9%,经阴道补片术后10.1%,腹部补片术后12.1% (p = 0.09)。在随访期间,多达三分之一的妇女报告了阴道膨出的症状,在2年和5年的随访中,经阴道补网手术后的发生率显著降低。脱垂的再手术以单部位为主;前路或根尖修复在原生组织和腹部补片手术后最常见,而经阴道修复后的再手术主要涉及后路或根尖室。40%的再手术采用补片。后房室和根尖房室脱垂手术是增加再手术风险的唯一因素(aOR 1.95 CI 1.30-2.92)。根据登记数据,只有1.6%的女性有手术治疗的补片并发症,而患者报告的补片暴露率和补片相关再手术率分别为6.5%和6.4%,两组补片之间没有显著差异。结论:脱垂术后再手术的远期风险与原位组织和补片增强手术相似,但因手术方式不同,再手术部位不同。经阴道和腹部补片修复后补片并发症发生率相似,大多数补片暴露不需要手术治疗。

Introduction

Embryo transfer at the blastocyst stage has become popular in assisted reproductive technology, but it is still a challenge for embryologists to select the embryos with the highest implantation potential. We aimed to investigate whether blastocyst development speed and blastocyst quality affect pregnancy and perinatal outcomes in single frozen–thawed blastocyst transfer (SFBT) cycles.

Material and Methods

We therefore conducted a meta-analysis to compare the pregnancy and perinatal outcomes after day 5 versus day 6 SFBT. Pregnancy and perinatal outcomes of SFBT included HCG positive rate, clinical pregnancy rate (CPR), live birth rate (LBR), miscarriage rate (MR), multiple pregnancy rate (MPR), ongoing pregnancy rate (OPR), ectopic pregnancy rate (EPR), mean birth weight, low birth weight (LBW) rate, rate of macrosomia, mean gestational age at birth, preterm birth rate, birth defects rate, and sex ratio (female/male).

Results

A total of 106 316 participants were included in this meta-analysis and were assigned to the D5 (n = 66 329) and D6 (n = 39 987) SFBT groups. Pooled analysis showed that the D5 SFBT group had a higher HCG positive rate (RR 1.24, 95% CI 1.14–1.34), CPR (RR 1.28, 95% CI 1.22–1.34), OPR (RR 1.36, 95% CI 1.21–1.53), LBR (RR 1.39, 95% CI 1.32–1.47), and a lower MR (RR 0.78, 95% CI 0.73–0.83) than the D6 SFBT group. No significant difference was observed between the D5 and D6 SFBT groups in other pregnancy and perinatal outcomes. Subgroup analysis comparing poor-quality D5 blastocysts with high-quality D6 blastocysts revealed no significant differences in most outcomes, except for a lower HCG positive rate (RR 0.92, 95% CI 0.87–0.97) and a higher rate of macrosomia (RR 2.13, 95% CI 1.05–4.31) in the poor-quality D5 group.

Conclusions

The findings suggested that transfer D5 blastocysts should be prioritized over D6 blastocysts in SFBT in clinical practice. Besides, poor-quality D5 blastocysts and D6 high-quality blastocysts exhibited comparable outcomes. Given the overall low quality of available evidence, the association between the pregnancy outcomes and blastocyst development speed requires further investigation.

在辅助生殖技术中,囊胚期胚胎移植已成为一种流行的方法,但如何选择着床潜力最大的胚胎仍然是胚胎学家面临的挑战。我们的目的是研究在单次冻融囊胚移植(SFBT)周期中,囊胚发育速度和囊胚质量是否影响妊娠和围产期结局。材料和方法:因此,我们进行了一项荟萃分析,比较SFBT第5天和第6天的妊娠和围产期结局。SFBT妊娠及围产期结局包括HCG阳性率、临床妊娠率(CPR)、活产率(LBR)、流产率(MR)、多胎妊娠率(MPR)、持续妊娠率(OPR)、异位妊娠率(EPR)、平均出生体重、低出生体重(LBW)率、巨大儿率、平均出生胎龄、早产率、出生缺陷率、性别比(男女)。结果:共有106 316名参与者被纳入本荟萃分析,并被分配到D5 (n = 66 329)和D6 (n = 39 987) SFBT组。合并分析显示,D5 SFBT组HCG阳性率(RR 1.24, 95% CI 1.14-1.34)、CPR (RR 1.28, 95% CI 1.22-1.34)、OPR (RR 1.36, 95% CI 1.21-1.53)、LBR (RR 1.39, 95% CI 1.32-1.47)高于D6 SFBT组,MR (RR 0.78, 95% CI 0.73-0.83)低于D6 SFBT组。D5和D6 SFBT组在其他妊娠和围产期结局方面无显著差异。比较质量差的D5囊胚与质量好的D6囊胚的亚组分析显示,除了质量差的D5囊胚HCG阳性率较低(RR 0.92, 95% CI 0.87-0.97)和巨大儿发生率较高(RR 2.13, 95% CI 1.05-4.31)外,大多数结果无显著差异。结论:在临床SFBT中,D5囊胚移植优先于D6囊胚移植。此外,质量差的D5囊胚和质量好的D6囊胚的结局相当。鉴于现有证据的总体质量较低,妊娠结局与囊胚发育速度之间的关系需要进一步调查。

Introduction

The main objective was to study the occurrence of intraoperative complications after emergency caesarean section during labor according to the type of hysterotomy extension performed.

Material and Methods

This was a single-center comparative study of hysterotomy extension by transverse traction (January 2015 to April 2017) versus cephalocaudal traction (May 2021 to February 2022). All women who underwent an emergency caesarean section (orange or red code) during these two periods were included. The primary endpoint was a composite of the occurrence of unintended extension, uterine pedicle injury, postpartum hemorrhage >1 L, and the blood product transfusion.

Results

The study included 767 patients. At least one intraoperative complication occurred in 122 women (21.4%) in the transverse traction group and in 33 (16.8%) women in the cephalocaudal traction group (OR 0.74, 95% CI [0.48–1.13]; p = 0.16). The incidence of these complications did not differ between groups after weighting (adjusted OR 0.78, 95% CI [0.52–1.19]; adjusted p = 0.25). Individual analysis of each component of the composite endpoint also showed no differences between groups.

Conclusions

In this study of emergency caesarean sections, the type of hysterotomy extension did not significantly influence the rate or type of intraoperative complications.

前言:本研究的主要目的是研究急诊剖宫产术中剖宫产术中并发症的发生情况。材料和方法:这是一项单中心比较研究,横向牵引(2015年1月至2017年4月)与头尾牵引(2021年5月至2022年2月)的子宫切开延伸。所有在这两个时期接受紧急剖腹产手术的妇女(橙色或红色代码)都包括在内。主要终点是发生意外伸展、子宫蒂损伤、产后出血bbb1l和输血的复合终点。结果:共纳入767例患者。横向牵引组122例(21.4%)发生术中并发症,头尾牵引组33例(16.8%)发生术中并发症(OR 0.74, 95% CI [0.48-1.13]; p = 0.16)。这些并发症的发生率在加权后各组间无差异(校正OR 0.78, 95% CI[0.52-1.19];校正p = 0.25)。综合终点各组成部分的个体分析也显示组间无差异。结论:本研究急诊剖宫产术中,剖宫产方式对术中并发症发生率及类型无显著影响。

导言:由于人工引产(IOL)在高收入国家越来越频繁,研究其对分娩体验的影响需要进一步关注。我们的目的是通过一项基于全国人口的调查,在常规实践中评估IOL与分娩经历之间的关系,并与自然分娩(SOL)进行比较。材料和方法:法国全国围产期调查(Enquête Nationale pembroinatale (ENP))是一项全国性研究,旨在2021年监测孕产妇和新生儿健康。来自法国大陆、活产、面对面访谈并参与2个月随访的妇女被纳入研究对象。在两个月大的时候,女性回答了“你对分娩有什么样的记忆?”,并被分为两组:“积极”和“消极”的分娩经历。我们使用单变量和多变量逻辑回归来比较人工晶状体和人工晶状体妇女的分娩经历。我们进行了三个敏感性分析:(1)将分娩的开始作为一个三类变量(SOL, IOL,宫颈成熟),(2)根据IOL的医学指征的存在,以及(3)在低风险妇女亚组中。最后,我们确定了人工晶状体与负面分娩经历(分娩并发症或手术分娩、分娩疼痛、分娩持续时间)之间通路的潜在中介,并使用中介模型来估计间接和残余影响。结果:6200例患者中,1777例(28.7%)行人工晶状体植入。结论:与单纯人工流产的女性相比,单纯人工流产的女性发生不良分娩经历的风险明显更高。我们的研究结果强调了对女性提供适当的有关人工流产的产前信息、共同决策以及对有不良分娩经历风险的女性进行更好的随访的必要性。

严重出生窒息(BA)及其导致的缺氧缺血性脑病(HIE)仍然是全球足月儿新生儿脑损伤和死亡的主要原因之一缺氧缺血性脑损伤的进展是渐进的,为开发更有效的治疗干预措施提供了机会。2,3对BA- hie的转化实验研究对于确定新的治疗方法至关重要,最好将重点放在适用于BA最普遍的中低收入国家的干预措施上因此,BA的实验模型需要很好地表征,以了解导致HIE的系统和大脑生理相互作用。HIE的病理生理是分阶段发展的缺氧缺血性损伤可导致原发性神经元死亡,其细胞机制已被深入研究。出生和复苏之后是长达6-15小时的潜伏期,其特征是氧化能代谢恢复,持续的兴奋性毒性,急性炎症和脑灌注不足。它为治疗干预提供了最佳窗口,因为在这一阶段,损伤的次要机制要么已经进展,要么已经触发。癫痫发作是第二阶段的标志之一,该阶段持续数天,在此期间多种致病机制进展。第三阶段从数周到数年,揭示出受侮辱的运动、认知和行为后果。尽管对ba - hie诱导的脑损伤的病理生理机制进行了广泛的研究,并寻找了新的神经保护干预措施,但目前使用的治疗方法仍然不足。对于足月新生儿,治疗性低温(TH)仍然是唯一确定的干预中度至重度HIE的方法,主要在专门的中心提供此外,长期脑损伤并非在全球范围内公平可及,即使在可获得的地方,也可能由多种原因造成,包括急性、亚急性或慢性缺氧、感染、炎症、遗传或代谢紊乱、颅内出血和中风。因此,这种复杂性强调了研究保护胎儿和新生儿大脑的新方法的必要性。许多基础研究和转化研究都是用动物模型进行的。然而,选择一个合适的模型面临着一些挑战,包括物种差异,神经发育阶段与人类新生儿的一致性,以及复制分娩时条件的窒息损伤的可靠诱导没有实验模型能完全复制人BA-HIE,这凸显了补充动物模型的价值。大鼠和小鼠是后生动物,脑发育与早产儿和足月人类新生儿分别在出生后5 - 6天和10 - 11天另一方面,最广泛使用的大型动物模型物种(绵羊和仔猪)是早熟的,出生时大脑相对成熟在实验工作和将结果应用于人类时,必须考虑到这种物种差异。与大型动物模型相比,啮齿动物模型提供数据更容易,成本更低。常用的BA-HIE啮齿动物模型包括单独全身性缺氧或单侧颈动脉结扎后应用,不限制二氧化碳清除。最近的啮齿动物模型通过降低吸入气体中的氧气和增加二氧化碳来模拟BA,从而引起全身缺氧和高碳酸血症,从而复制受损的气体交换。这种模式之间的差异值得注意,因为每次阴道分娩都涉及一定程度的缺氧和高碳酸血症,这触发了系统水平的内源性保护机制,通常被称为外周化学反射。2,6 -8胎儿羊被认为是研究胎儿HIE和神经保护的最相关的翻译模型之一。胎羊的循环和心血管反应与足月的人类胎儿相似。6,7此外,绵羊胎儿的相对较大的尺寸便于手术器械,并且可以在没有明显早产风险的情况下进行纵向监测。此外,在类似新生儿重症监护病房的条件下,可以在产后护理期间研究新型治疗方法的效果。胎儿羊模型在建立硫酸镁作为临床验证的早产儿神经保护治疗方面发挥了关键作用。在足月,三分之二的HIE病例与活产期间胎儿窒息和亚急性低氧血症有关,因为在宫缩期间流向胎盘和胎儿的血流量减少。仪器胎儿羊脐带闭塞模型复制了子宫收缩和亚急性发展的胎儿低氧血症的后果。通常应用在0.6到0之间。 妊娠期与早产儿到足月人类胎儿的神经发育阶段相一致这种侮辱可以被设计成模仿人类分娩时的并发症,但在这个版本的模型中,所产生的病理生理变化必须在子宫内进行,因为绵羊的肺在妊娠期很晚才成熟。尽管如此,该模型已成为弥合啮齿动物模型和人类临床试验之间差距的宝贵工具。由于TH在减轻严重窒息新生儿HIE及其终身后果方面的疗效相对有限,因此显然需要补充治疗。此外,新疗法的时机也可能是一个重要的问题,因为导致HIE的大脑过程比TH的发病要早得多。许多干预措施主要是在动物模型中提出和研究的,包括远程缺血后适应、褪黑激素、大麻素、促红细胞生成素、咖啡因等。然而,到目前为止,还没有证明它对人类有显著的益处。与寻找单一分子靶点相比,增强系统级(以及脑特异性)内源性保护机制被认为是一种更有前途的方法。用于HIE和神经保护研究的翻译动物模型的选择必须考虑到发育阶段、损伤类型和生理背景,因为这些因素对研究结果的翻译有效性有重要影响。同样重要的是围产期过渡:宫内损伤不同于产后循环开始后的损伤,出生前的恢复不等同于通过分娩和稳定恢复。最佳模型必须定义相对于转移的损伤,并以临床相关的方式管理血流动力学、通气和再氧合。在过渡时期,二氧化碳(CO2)生理学值得关注。二氧化碳强烈调节脑血流:低碳酸血症使脑血管收缩并可能导致灌注不足,而高碳酸血症则使脑血管扩张。过早的强力通气会在最脆弱的时刻引起突然的低碳酸血症。建议避免医源性低碳酸血症和耐受允许性高碳酸血症,这与外周化学反射在心肺适应中的作用一致调节二氧化碳水平的实验模型可能有助于确定优化脑灌注的策略,并在产后护理期间支持神经保护潜力。分娩时的主要临床目标是防止严重窒息导致脑损伤。然而,仍然没有最佳或明确的策略来实现这一目标。由于目前没有更好的治疗选择,TH仍然是足月新生儿BA-HIE的标准治疗方法。因此,目前正在探索的许多假定的辅助疗法值得在大型动物模型中进行系统测试,以阐明其潜力以及可能的副作用。此后,临床试验也应该围绕狭义的、同质的患者队列来设计,以提高对新治疗效果的检测。出生时的事件会影响一生的结果,因此即使是早期护理的微小改善也会产生重大影响。需要可信的、特征良好的实验模型,将实验生理学、产科、新生儿学、神经科学和生物医学工程结合起来,以确定有前景的神经保护策略。这一途径可能为更全面的神经保护铺平道路。没有宣布。数据共享不适用于本文,因为在当前研究期间没有生成或分析数据集。
