The use of comprehensive, whole-genome amplification (WGA)-based diagnostic technology showed a small decrease for PGT-M (from 15% in 2016-2017 to 12% in 2018) and for PGT-SR (from 50% in 2016-2017 to 44% in 2018). Comprehensive testing was, however, the main technology for PGT-A (from 93% in 2016-2017 to 98% in 2018). WGA-based testing was also widely used for concurrent PGT-M/SR with PGT-A, as a standalone technique (74%) or in combination with PCR or FISH (24%).

研究问题:与往年相比,2018年胚胎植入前基因检测(PGT)的趋势和发展是什么?总结:在第21个PGT数据集中观察到的主要趋势是,对PGT-A和同时进行的PGT- m /SR/A进行营养外胚层活检最常应用于PGT-A和PGT- m /SR/A,而对于PGT- m和PGT-SR,单细胞PCR和FISH检测仍然盛行。已知情况:自1997年成立以来,ESHRE PGT联盟一直在收集和分析主要来自欧洲PGT中心的数据。迄今为止,已发布了20个数据集和前10年数据收集的概述。研究设计规模持续时间:2018年1月1日至2018年12月31日期间进行的PGT分析数据,分析后随访2年,由参与中心自愿提供。数据是通过一个基于基因分析的在线平台收集的,该平台自2016年以来一直在使用。参与者/材料设置方法:44个中心提交了活检方法、诊断技术和临床结果的数据。单基因疾病(PGT- m)和/或染色体结构重排(PGT- sr)的PGT多于一项,或PGT模式数据不一致的记录被排除在外。所有在分析后2年内进行的移植都包括在内,从而可以计算累积妊娠率。数据分析、计算以及图表和表格的准备由专家共同作者进行。主要结果和偶然性的作用:2018年目前收集的数据共包括PGT- m分析1388项,PGT-SR分析462项,PGT非整倍体(PGT- a)分析3003项,PGT- m /SR与PGT- a并发分析338项。囊胚活检在PGT-M中的应用逐渐增加(从2016-2017年的19%增加到2018年的33%),在PGT-SR中的应用也是如此(从2016-2017年的30%增加到2018年的33%),并已成为PGT-A(从2016-2017年的87%增加到2018年的98%)和PGT-M/SR与PGT-A同时使用的活检阶段(96%)。使用基于全基因组扩增(WGA)的综合诊断技术显示,PGT-M(从2016-2017年的15%降至2018年的12%)和PGT-SR(从2016-2017年的50%降至2018年的44%)的比例略有下降。然而,综合检测是PGT-A的主要技术(从2016-2017年的93%上升到2018年的98%)。基于wga的检测也广泛用于与PGT-A同时进行的PGT-M/SR,作为单独技术(74%)或与PCR或FISH结合(24%)。滋养外胚层活检和综合检测策略与每次胚胎移植更高的诊断效率和改善的临床结果有关。注意的局限性:研究结果适用于44个参与中心提交的数据,并不代表PGT的全球趋势。这份手稿中没有提供出生婴儿健康的细节。研究结果的更广泛意义:联盟数据集为跟踪PGT实践的趋势提供了宝贵的资源。研究经费/竞争利益:该研究没有外部资金,所有费用由ESHRE承担。没有任何相互竞争的利益。试验注册号:无。

研究问题:在先前早孕流产(PL)后的后续妊娠中,夫妻对医疗保健和支持的需求是什么?在整个妊娠过程中需求是如何变化的?概要回答:夫妇在怀孕的前20周描述了未满足的孕期护理需求,并对怀孕其余时间提供的护理更满意。已知情况:尽管早期妊娠妊娠很常见(约占妊娠的25%),但缺乏研究来指导实践,以优化治疗和支持未来妊娠。研究中对这一问题的重视程度较低,人们普遍认为夫妻在经历过产后忧郁症后应该“再试一次”。与没有经历过产后忧郁症的女性相比,有产后忧郁症的女性在怀孕前三个月的焦虑程度有所增加。没有纵向研究探讨夫妻在整个怀孕期间的需求是什么,以及这些需求如何随着时间的推移而变化。研究设计规模持续时间:这是一项定性纵向双元(联合)访谈研究。总共有15对夫妇在怀孕期间接受了四次采访。这些夫妇是从哥本哈根流产队列研究项目中招募的。面试在医院或大学进行,或者在网上进行。访谈时间从20到91分钟不等(平均54分钟)。参与者/材料设置方法:纳入标准包括有一至两个早期分娩的夫妇,他们自我报告有新的怀孕,并愿意一起接受英语访谈。对夫妇进行了四次面谈:在妊娠试验呈阳性后,每三个月一次。访谈记录和数据分析使用主题分析来比较和对比夫妇在怀孕的四个时期和整个怀孕期间的需求。一对同性伴侣和14对异性伴侣参与了调查。主要结果和偶然性的作用:夫妇的需求在整个怀孕期间被分为两个主要的纵向主题,按20周的扫描进行划分。在每个纵向主题中,有两个主题代表每个时间段。在纵向主题“前20周:护理方面的“可怕”差距”中,有两个主题:妊娠测试呈阳性:“告诉他们这不是同一个怀孕”和“我们渴望有人照顾我们”。丹麦公共医疗保健系统提供的标准妊娠护理包括12周和20周的扫描。虽然所有夫妇都希望在怀孕早期对胎儿进行额外的扫描和监测,以提供保证并及早发现问题,但他们在转诊和提供的护理方面描述了相当大的差异。夫妻双方都表达了对怀孕的高度担忧和焦虑,特别是孕妇在最初的几周内描述了“从一次扫描到另一次扫描的生存”。夫妇们在任何提供扫描或付费的舒适扫描中进行扫描,但这导致了支离破碎的护理。相反,他们希望继续护理,并承认和敏感地认识到,产后怀孕与第一次怀孕是不同的。在纵向主题“第二个20周:护理系统中的安全”中,有两个主题:妊娠中期:“我认为我们得到了很好的照顾”和妊娠晚期:“与其说是“需要知道”,不如说是“很高兴知道”一切都好。”夫妇们报告说,他们的痛苦程度较低,在这段时间里,对护理的总体需求得到了满足。他们对定期或延长的产前支持表示总体满意,尽管在前20周,需要对其PL病史进行额外的确认和敏感。夫妇们表示,如果他们有任何担忧或问题,他们可以获得助产士/护士的24小时电话支持,这让他们感到更安全。注意的局限性:参与者是从一项正在进行的队列研究中自我选择的,该研究是针对在医院就诊的PL患者进行的。单身女性不包括在研究中。这项研究仅限于丹麦的数据收集;然而,其他拥有公共医疗保健系统的国家可能在提供产前保健、复发性妊娠丢失(RPL)诊所提供的护理和私人扫描方面提供类似的服务。研究结果的更广泛意义:研究结果强调,早期早产会增加对后续妊娠的监测和护理需求。本研究强调了在妊娠护理方面存在的差距,因为在获得产前护理之前,在新怀孕的最初几周,他们对监测和支持的需求很高,并且在他们有多个PLs之前,可以转到RPL单位。研究资金/竞争利益:该项目已获得欧盟地平线2020研究和创新计划的资助,根据Marie Skłodowska-Curie资助协议No . 101028172 for E.K. 哥本哈根流产队列研究由生物创新研究所基金会资助。H.S.N.获得了Freya Biosciences、Ferring Pharmaceuticals、生物创新研究所、教育部、诺和诺德基金会、Augustinus Fonden、Oda og Hans Svenningsens Fond、Demant Fonden、Ole Kirks Fond和丹麦独立研究基金的科学资助。H.S.N.收到Ferring Pharmaceuticals、Merck、Astra Zeneca、Cook Medical、Gedeon Richter和Ibsa Nordic的讲座和演讲的个人付款或酬金。所有其他作者声明没有竞争利益。

We read with interest the article by Melo et al. regarding progesterone levels and ART outcomes in all regimens used for priming frozen embryo transfers (FET) (Melo et al., 2022). This article follows a slew of publications on the topic and a metaanalysis conducted by these very authors (Melo et al., 2021). According to the mustered studies, lower serum progesterone levels on, or near, the day of embryo transfer (ET) in women receiving vaginal progesterone are associated with poorer FET outcomes (Melo et al., 2021). The present article by Melo et al. is new in that it studies the links between serum progesterone levels and the outcomes in all forms of treatment used for priming FET (Melo et al., 2022). This also includes the situation when subcutaneous progesterone (LubionR ) 25 mg BID is used exclusively (Melo et al., 2022). In this particular case, the study shows a biphasic relationship between serum progesterone levels and FET outcome with a sharp decrease in outcome when serum progesterone exceeds 16.3 ng/ml on the day of ET (Melo et al., 2022). Based on their observation, the authors suggest that serum levels of progesterone that exceed this mark exert a counterproductive effect on embryo implantation. Aside from the weaknesses of their study—for instance, there is no indication as to why patients were prescribed HRT using exclusively subcutaneous progesterone rather than other regimens, and despite limited evidence for biological plausibility and a relatively small cohort (n1⁄4 57)—Melo et al. conclude that this regimen can harm FET implantation (Melo et al., 2022), which could potentially be misleading for patient and medical care providers. Melo et al. (2022) also stress the fact that their present study is the first on the topic that uses a prospective (though not randomized) design. Yet all studies—retrospective or prospective—rely, for the quality of their conclusion, on the data coming in. Melo et al.’s current study, while prospective, is indeed rather complex (Melo et al., 2022). Aside of being prospective and multicentric, it mixes several different protocols for timing FET without indicating the reasons retained by clinicians for choosing a particular approach. Furthermore, it combines single and multiple embryo transfers and, for HRT regimens, limited information on the use or not of prior pituitary desensitization. Specifically, for the topic that attracted our attention, the link between serum progesterone levels and FET outcome in the 57 women primed with subcutaneous progesterone 25 mg BID, the authors do not tell us the motives that led them to opt for this HRT regimen option in these patients.

{"title":"Hiding in plain sight.","authors":"Paul Pirtea, Dominique de Ziegler, James Toner, Richard Scott, Jean-Marc Ayoubi","doi":"10.1093/hropen/hoad015","DOIUrl":"https://doi.org/10.1093/hropen/hoad015","url":null,"abstract":"We read with interest the article by Melo et al. regarding progesterone levels and ART outcomes in all regimens used for priming frozen embryo transfers (FET) (Melo et al., 2022). This article follows a slew of publications on the topic and a metaanalysis conducted by these very authors (Melo et al., 2021). According to the mustered studies, lower serum progesterone levels on, or near, the day of embryo transfer (ET) in women receiving vaginal progesterone are associated with poorer FET outcomes (Melo et al., 2021). The present article by Melo et al. is new in that it studies the links between serum progesterone levels and the outcomes in all forms of treatment used for priming FET (Melo et al., 2022). This also includes the situation when subcutaneous progesterone (LubionR ) 25 mg BID is used exclusively (Melo et al., 2022). In this particular case, the study shows a biphasic relationship between serum progesterone levels and FET outcome with a sharp decrease in outcome when serum progesterone exceeds 16.3 ng/ml on the day of ET (Melo et al., 2022). Based on their observation, the authors suggest that serum levels of progesterone that exceed this mark exert a counterproductive effect on embryo implantation. Aside from the weaknesses of their study—for instance, there is no indication as to why patients were prescribed HRT using exclusively subcutaneous progesterone rather than other regimens, and despite limited evidence for biological plausibility and a relatively small cohort (n1⁄4 57)—Melo et al. conclude that this regimen can harm FET implantation (Melo et al., 2022), which could potentially be misleading for patient and medical care providers. Melo et al. (2022) also stress the fact that their present study is the first on the topic that uses a prospective (though not randomized) design. Yet all studies—retrospective or prospective—rely, for the quality of their conclusion, on the data coming in. Melo et al.’s current study, while prospective, is indeed rather complex (Melo et al., 2022). Aside of being prospective and multicentric, it mixes several different protocols for timing FET without indicating the reasons retained by clinicians for choosing a particular approach. Furthermore, it combines single and multiple embryo transfers and, for HRT regimens, limited information on the use or not of prior pituitary desensitization. Specifically, for the topic that attracted our attention, the link between serum progesterone levels and FET outcome in the 57 women primed with subcutaneous progesterone 25 mg BID, the authors do not tell us the motives that led them to opt for this HRT regimen option in these patients. Melo et al.’s findings of FET outcomes when timed with subcutaneous progesterone (LubionR ) 25 mg BID (Melo et al., 2022) are extremely puzzling with respect to long established knowledge on progesterone levels and implantation.

Abstract STUDY QUESTION Does cancer itself, before any gonadotoxic treatment, affect ovarian function in reproductive-aged patients? SUMMARY ANSWER Our study revealed that women with cancer may have decreased ovarian reserve markers even before cancer therapy. WHAT IS KNOWN ALREADY With the field ‘oncofertility’ improving rapidly, cancer therapy-mediated ovarian damage is well characterized. However, there is a controversy about whether cancer itself affects ovarian function before gonadotoxic treatment. STUDY DESIGN, SIZE, DURATION We conducted a systematic meta-analysis investigating the association between cancer and ovarian function prior to gonadotoxic treatment. Titles or abstracts related to ovarian reserve (e.g. anti-Müllerian hormone (AMH), antral follicle count (AFC), or basal follicle-stimulating hormone (FSH)) combined with titles or abstracts related to the exposure (e.g. cancer*, oncolog*, or malignan*) were searched in PubMed, Embase, and Web of Science databases from inception to 1 February 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS We included cohort, case-control, and cross-sectional studies in English that examined ovarian reserve in reproductive-aged patients (18–45 years) with cancer compared to age-matched controls before cancer treatment. The quality of the included studies was assessed by ROBINS-I. Fixed or random effects were conducted to estimate standard or weighted mean difference (SMD or WMD, respectively) and CI. Heterogeneity was assessed by the Q test and I2 statistics, and publication bias was evaluated by Egger’s and Begg’s tests. MAIN RESULTS AND THE ROLE OF CHANCE The review identified 17 eligible studies for inclusion. The results showed that cancer patients had lower serum AMH levels compared to healthy controls (SMD = −0.19, 95% CI = −0.34 to −0.03, P = 0.001), especially women with hematological malignancies (SMD = −0.62, 95% CI = −0.99 to −0.24, P = 0.001). The AFC was also decreased in patients with cancer (WMD = −0.93, 95% CI = −1.79 to −0.07, P = 0.033) compared to controls, while inhibin B and basal FSH levels showed no statistically significant differences. LIMITATIONS, REASONS FOR CAUTION Serum AMH and basal FSH levels in this meta-analysis showed high heterogeneity, and the small number of studies contributing to most subgroup analyses limited the heterogeneity analysis. Moreover, the studies for specific cancer subtypes may be too small to draw conclusions; more studies are needed to investigate the possible impact of cancer type and stage on ovarian function. WIDER IMPLICATIONS OF THE FINDINGS Our study confirmed the findings that cancer per se, especially hematological malignancies, negatively affects serum AMH level, and AFC values of reproductive-aged women. However, the lower AMH levels and AFC values may also be due to the changes in ovarian physiology under oncological conditions, rather than actual lower ovarian reserves. Based on the meta-analysis, clinicians should raise awareness abo
研究问题:在任何促性腺毒素治疗之前,癌症本身是否会影响育龄患者的卵巢功能?摘要回答:我们的研究表明,患有癌症的女性甚至在癌症治疗前卵巢储备标志物就可能下降。已知情况:随着“肿瘤生育”领域的迅速发展,癌症治疗介导的卵巢损伤得到了很好的表征。然而,在促性腺毒素治疗前,癌症本身是否会影响卵巢功能存在争议。研究设计规模持续时间:我们进行了一项系统的荟萃分析,调查促性腺毒素治疗前癌症与卵巢功能之间的关系。在PubMed、Embase和Web of Science数据库中检索从成立到2022年2月1日期间与卵巢储备相关的标题或摘要(如抗卵泡激素(AMH)、窦卵泡计数(AFC)或基底促卵泡激素(FSH))以及与暴露相关的标题或摘要(如cancer*、oncolog*或malignant *)。参与者/材料设置方法:我们纳入了队列研究、病例对照研究和英语横断面研究,这些研究检查了癌症治疗前育龄患者(18-45岁)与年龄匹配的对照组的卵巢储备。采用ROBINS-I评估纳入研究的质量。采用固定效应或随机效应来估计标准或加权平均差(分别为SMD或WMD)和CI。异质性采用Q检验和I2统计量评估,发表偏倚采用Egger’s和Begg’s检验评估。主要结果和偶然性的作用:本综述确定了17项符合纳入条件的研究。结果显示,与健康对照相比,癌症患者的血清AMH水平较低(SMD = -0.19, 95% CI = -0.34 ~ -0.03, P = 0.001),特别是患有血液恶性肿瘤的女性(SMD = -0.62, 95% CI = -0.99 ~ -0.24, P = 0.001)。与对照组相比,癌症患者的AFC也降低(WMD = -0.93, 95% CI = -1.79 ~ -0.07, P = 0.033),而抑制素B和基础FSH水平无统计学差异。局限性:本荟萃分析中血清AMH和基础FSH水平显示出较高的异质性,并且对大多数亚组分析的研究数量较少,限制了异质性分析。此外,针对特定癌症亚型的研究可能规模太小,无法得出结论;需要更多的研究来调查癌症类型和分期对卵巢功能的可能影响。研究结果的更广泛意义:我们的研究证实了癌症本身,特别是血液恶性肿瘤,对育龄妇女的血清AMH水平和AFC值产生负面影响。然而,较低的AMH水平和AFC值也可能是由于肿瘤条件下卵巢生理的变化,而不是卵巢储备的实际降低。基于荟萃分析,临床医生应该提高对在抗癌治疗前有兴趣追求生育保护策略的年轻癌症女性可能需要个性化方法的认识。研究经费/利益竞争:国家自然科学基金项目(81873824、82001514、81902669)和武汉市科技局应用基础研究计划项目(2019020701011436)资助。作者声明他们没有利益冲突。注册号:普洛斯彼罗(CRD42021235954)。

Study question: Can a home-use device be used to predict serum hormone levels?
Summary answer: A home-use device can predict urinary hormone values which are well-correlated to serum concentrations of respective hormones and hence can be used as a proxy for serum measurements.
What is known already: Home-use devices that predict ovulation are calibrated against the actual day of ovulation. However, the correlation of any quantitative system to serum hormone concentrations has not been established.
Study design size duration: A total of 73 data points obtained from 20 participants across different phases of the menstrual cycle, i.e. bleeding days, follicular phase and luteal phase were used to establish the correlation between serum hormones and urinary metabolite values. Single data points from 20 random users were used to assess the correlation established.
Participants/materials setting methods: Participants were women in the fertile age groups and only current users of the home-use device. Selection was done based on inclusion and exclusion criteria. Blood hormones were tested using chemiluminescent immunoassays and urinary measurements were taken on the home-use device at home.
Main results and the role of chance: Serum estradiol (E2), progesterone (P4) and LH were correlated with urinary estrone-3-glucuronide (E3G), pregnanediol glucuronide (PdG) and LH with an R2 of 0.96, 0.95 and 0.98, respectively. Repredicted serum concentration obtained by using the correlation equation had a correlation of 0.92, 0.94 and 0.93 in unknown samples.
Limitations reasons for caution: The study was designed to include women who have normal cycle lengths regularly; therefore, the values obtained were in the normal range. Certain infertility conditions may cause the values to be higher and correlation in such cases needs to be established.
Wider implications of the findings: The results of this study imply a new tool that can be used by fertility specialists as a proxy for blood tests whenever required. Extended study on this system can enable its use in assisted reproductive techniques as well.
Study funding/competing interests: No funding was received for this study. S.P. and D.D. are employees of the research and development division of Samplytics Technologies Pvt. Ltd. which is a forwarder for Inito Inc., USA. A.R. and V.A.V. are co-founders of Inito Inc., USA.
Trial registration number: The trial was registered at the International Standard Randomised Controlled Trial Number (ISRCTN) registry (Identifier: ISRCTN15534557).

<p><strong>Study question: </strong>What is the additional value of the comprehensive complication index (CCI) and ClassIntra system (classification for intraoperative adverse events (ioAEs)) in adverse event (AE) reporting in (deep) endometriosis (DE) surgery compared to only using the Clavien-Dindo (CD) system?</p><p><strong>Summary answer: </strong>The CCI and ClassIntra are useful additional tools alongside the CD system for a complete and uniform overview of the total AE burden in patients with extensive surgery (such as DE), and with this uniform data registration, it is possible to provide greater insight into the quality of care.</p><p><strong>What is known already: </strong>Uniform comparison of AEs reported in the literature is hampered by scattered registration.
