The antagonistic pleiotropy hypothesis is one of the leading theories in the evolutionary origin of aging. It states that mutations contributing to aging could be positively selected for if they are advantageous early in life and promote earlier reproduction or more offspring. The evidence supporting the antagonistic pleiotropy hypothesis in humans is mixed and lacks unambiguous genome-wide support. The UK Biobank contains the genotypes and various phenotypes of 500,000 participants, offering an opportunity to test the antagonistic pleiotropy hypothesis in humans. This analysis aimed to use the UK Biobank to determine whether genetic variants influencing reproduction are likely to affect lifespan, whether pleiotropy between reproduction and lifespan are largely antagonistic, and whether pleiotropic mutations promoting reproduction but causing aging are favored by natural selection. In addition, potential molecular mechanisms linking reproduction to aging were investigated. Genetic correlation between 2 phenotypic traits was defined as the proportion of variance that the 2 traits share due to genetic causes and is a measure of the contribution of pleiotropy to the covariation of the traits. Four reproductive traits were focused on negative age at first birth, negative age at first sex, number of children fathers, and age at menopause, with larger values of these traits corresponding to higher reproduction. Two life span traits were examined: father's age at death and mother's age at death. Data were available for a total of 276,406 UK Biobank participants, and 583 genetic variants were reported to be associated with at least 1 reproductive trait. A strong, negative genetic correlation was observed between the 3 reproductive traits and 2 life span traits, supporting the antagonistic pleiotropy hypothesis. Individuals ranked in the top third in polygenic score (PGS) for the 3 reproductive traits had a significantly lower probability of survival to age 76 (SV76) than that of individuals ranked in the bottom third. Compared with randomly selected polymorphisms, those impacting reproduction were 5 times more likely to affect life span and 7.5 times more likely to affect life span antagonistically. Among individuals with the same number of children ever born, SV76 was negatively correlated with the PGS for each of the 4 reproductive traits. In this study, the evidence shows a strong negative genetic correlation between reproduction and parental life span, as well as between parental reproduction and parental life span. This supports the antagonistic pleiotropy hypothesis of aging in humans.
拮抗多效假说是衰老进化起源的主要理论之一。该假说认为,如果导致衰老的突变在生命早期是有利的,并能促进更早的繁殖或更多的后代,那么这些突变就会被积极选择。支持人类拮抗多效性假说的证据不一,缺乏明确的全基因组支持。英国生物数据库包含 50 万名参与者的基因型和各种表型,为在人类中检验拮抗多效假说提供了机会。这项分析旨在利用英国生物库确定影响生殖的基因变异是否可能影响寿命,生殖和寿命之间的多效性是否在很大程度上是拮抗的,以及促进生殖但导致衰老的多效性突变是否受到自然选择的青睐。此外,还研究了生殖与衰老之间的潜在分子机制。两个表型性状之间的遗传相关性被定义为两个性状因遗传原因而共享的变异比例,是衡量多效性对性状协变的贡献的一个指标。四个生殖性状的重点是负初生年龄、负初性年龄、父亲的子女数和绝经年龄,这些性状的数值越大,生殖能力越强。还研究了两个寿命特征:父亲的死亡年龄和母亲的死亡年龄。共有 276,406 名英国生物库参与者的数据可用,据报道,583 个遗传变异与至少一个生殖特征相关。在 3 个生殖特征和 2 个寿命特征之间观察到了强烈的负遗传相关性,支持拮抗多效性假说。在 3 个生殖性状的多基因得分(PGS)中,排名前三分之一的个体存活到 76 岁的概率(SV76)明显低于排名后三分之一的个体。与随机选择的多态性相比,那些影响生殖的多态性影响寿命的可能性要高出5倍,拮抗性影响寿命的可能性要高出7.5倍。在生育子女数量相同的个体中,SV76 与 4 种生殖特征中每一种的 PGS 都呈负相关。在这项研究中,证据显示生殖与父母寿命之间以及父母生殖与父母寿命之间存在很强的遗传负相关。这支持了人类衰老的拮抗多效性假说。

In the United States, adherence for cervical cancer screening decreased from 86% to 77% between 2005 and 2019. Over 50% of cervical cancers are diagnosed in individuals overdue for screening, and promoting access and adherence is essential. Unlike traditional Papanicolaou testing, human papillomavirus (HPV) screening can use self-collected samples, which have comparable sensitivity and specificity to clinician-collected samples. Self-collecting has been shown to increase screening adherence, possibly by circumventing important barriers such as scheduling clinic appointments and negativity about pelvic examinations. Despite this, most individuals in prior studies remained unscreened with low follow-up of HPV-positive results, and kit uptake among populations that are screening adherent or have unknown screening history is unknown. The STEP trial (self-testing options in the era for primary HPV screening for cervical cancer) was a parallel, single-blind, randomized clinical trial comparing cervical cancer screening completion across groups of individuals with due (screening-adherent), overdue, or unknown screening history. Participants were randomized to traditional care (patient reminders and clinician electronic health record [HER] alerts), education (usual care plus educational materials about screening), direct mail (traditional care plus educational materials plus a mailed HPV self-collection kit), or to opt in (traditional care plus educational materials plus the option to request a self-collection kit). Patients were identified using the Kaiser Permanente Washington HER and administrative claims. Eligible participants were females aged 30 to 64 years with current Kaiser Permanente Washington insurance and primary care, intact cervix, who were either due or overdue for screening. The primary study outcome was screening completion within 6 months after randomization, which could be done either in clinic or using the self-collection kit. Modified Poisson regression was used to estimate relative risk (RR) of screening completion for the direct-mail and opt-in groups, relative to the education group. A total of 32,771 participants were randomized between November 2020 and January 2022, of which 13,356 were due for screening, 8682 were overdue, and 10,733 had unknown screening history. Of those due for screening, the RR for screening completion was 1.30 (95% confidence interval [CI], 1.23–1.36; absolute difference, 14.1% [95% CI, 11.2%–16.9%]) for direct mail and 1.07 (95% CI, 1.02–1.12; absolute difference, 3.5% [95% CI, 1.2%–5.7%]) for the opt-in group compared with education. Of those overdue for screening, the RR for screening completion was 1.90 (95% CI, 1.68–2.16; absolute difference 16.9% [95% CI, 13.8%–20.0%]) for direct mail compared with education. Of those with unknown screening history, the RR for screening completion was 1.14 (95% CI, 1.03–1.25; absolute difference 2.2% [95% CI, 0.5%–3.9%]) for the opt-in group compared with educa
在美国,宫颈癌筛查的坚持率在 2005 年至 2019 年间从 86% 降至 77%。超过 50%的宫颈癌是在逾期未接受筛查的人群中确诊的,因此促进筛查的普及和坚持筛查至关重要。与传统的巴氏检测不同,人类乳头瘤病毒(HPV)筛查可以使用自采样本,其敏感性和特异性与临床医生采集的样本相当。有研究表明,自取样本可以提高筛查的依从性,这可能是通过绕过一些重要的障碍,如预约门诊时间和对盆腔检查的否定。尽管如此,在之前的研究中,大多数人仍未接受筛查,HPV 阳性结果的随访率很低,而坚持筛查或筛查史不详的人群对试剂盒的接受程度也不得而知。STEP试验(宫颈癌HPV初筛时代的自我检测选择)是一项平行、单盲、随机临床试验,它比较了应接受筛查(坚持筛查)、逾期未接受筛查或筛查历史未知人群的宫颈癌筛查完成情况。参与者被随机分配到传统护理(患者提醒和临床医生电子健康记录 [HER] 提醒)、教育(常规护理加筛查教育材料)、直接邮寄(传统护理加教育材料加邮寄 HPV 自取试剂盒)或选择参与(传统护理加教育材料加申请自取试剂盒的选项)。患者身份通过华盛顿州 Kaiser Permanente HER 和行政报销单确定。符合条件的参与者为年龄在 30 至 64 岁之间、目前在华盛顿州凯泽医疗保险和初级保健机构就医、宫颈完好、筛查到期或逾期的女性。主要研究结果是在随机分配后 6 个月内完成筛查,筛查可在诊所或使用自取工具包完成。采用修正泊松回归估算了直邮组和选择参加组相对于教育组完成筛查的相对风险(RR)。在2020年11月至2022年1月期间,共有32771名参与者接受了随机筛查,其中13356人到期接受筛查,8682人逾期未接受筛查,10733人筛查历史未知。在到期筛查者中,直邮组与教育组相比,筛查完成率为 1.30(95% 置信区间 [CI],1.23-1.36;绝对差异,14.1% [95% CI,11.2%-16.9%]),选择接受组为 1.07(95% 置信区间 [CI],1.02-1.12;绝对差异,3.5% [95% CI,1.2%-5.7%])。在逾期未接受筛查的人群中,直邮组与教育组相比,筛查完成率为 1.90(95% CI,1.68-2.16;绝对差异为 16.9% [95% CI,13.8%-20.0%])。在筛查历史未知的人群中,与教育相比,选择接受组完成筛查的 RR 为 1.14(95% CI,1.03-1.25;绝对差异 2.2% [95% CI,0.5%-3.9%])。这项随机对照试验的结果表明,与单纯的教育相比,直接邮寄 HPV 自取试剂盒可使宫颈癌筛查率提高 14% 以上。在应进行筛查或逾期未进行筛查的参与者中,效果相似,而且发现选择接受的方法对筛查的增加微乎其微。

Many chromosome abnormalities are commonly observed and can lead to early pregnancy loss, miscarriage, or the birth of children with chromosomal defects. Such abnormalities are considered a major factor in the low pregnancy rate after assisted reproductive technology and natural conception. Preimplantation genetic testing for aneuploidy (PGT-A) aims to minimize the transfer of aneuploid embryos. Embryonic aneuploidies arising from errors in meiosis have an incidence of approximately 25% in embryos from women younger than 35 years, to more than half in embryos from women aged older than 35 years. Although these embryos are able to develop to the blastocyst stage, they tend to be of lower morphological quality. A recent multicenter randomized clinical trial (ESTEEM) analyzed polar bodies (PBs) from women after intracytoplasmic sperm injection aged between 36 and 40 years using microarrays in 205 cycles and found that the transfer of embryos from euploid oocytes did not lead to a higher live birth rate but was associated with a reduction in the number of embryo transfers and miscarriages. This study aimed to evaluate all PB results from this RCT and characterize the types of chromosomal abnormalities and the chromosomes most frequently affected. The ESTEEM trial obtained biopsy of first (PB1) and second (PB2) PB in the cohort receiving PGT-A and analyzed them using array comparative genomic hybridization (aCGH). A total of 693 PB pairs had full results available, including 676 confirmed fertilized oocytes. Chromosome segregations, including likely underlying mechanisms, from these pairs are reported here. To estimate the reliability of the aCGH procedure, 72 PB pairs from a single center were reanalyzed using next-generation sequencing (NGS). Embryos were classified into 4 categories based on morphology: good, fair, poor, and degenerated. A comparative analysis was performed to assess the association between chromosome status and embryo quality as well as study group (PGT-A vs control) and embryo quality. A total of 213/676 oocytes were euploid and 413/676 were aneuploid, whereas in the remaining 50 oocytes, an abnormality observed in PB1 was compensated by an abnormality in PB2. A total of 693 PB pairs reported chromatic numbers with results for 15,939 chromosomes. An abnormal segregation, in PB1 and/or PB2, was observed in 1162 chromosomes (7.3%) in 461 PB pairs. Chromosomes 22 (16.7%), 16 (16.6%), 19 (14.4%), 21 (13.7%), and 15 (12.4%) had the highest frequencies for abnormal segregations. The abnormal segregations were compatible with precocious separation of sister chromatids in meiosis 1 (M1) (n = 568; 48.9%), nondisjunction of chromatics in meiosis 2 (M2) or reverse segregation (n = 417; 35.9%), and nondisjunction in M1 (n = 65; 5.6%). However, 112 chromosomes had segregation patterns that could not be categorized into 1 of the 9 known mechanisms causing aneuploidy in oocytes. Concordance between aCGH and NGS was obtained for both PBs for
常见的染色体异常有很多,可导致早孕流产、流产或出生染色体缺陷儿。这些异常被认为是辅助生殖技术和自然受孕后怀孕率低的主要因素。非整倍体胚胎植入前基因检测(PGT-A)旨在尽量减少非整倍体胚胎的移植。在 35 岁以下女性的胚胎中,由减数分裂错误引起的胚胎非整倍体发生率约为 25%,而在 35 岁以上女性的胚胎中,非整倍体发生率则超过一半。虽然这些胚胎能发育到囊胚阶段,但形态质量往往较低。最近的一项多中心随机临床试验(ESTEEM)使用微阵列分析了 205 个周期中 36 至 40 岁女性卵胞浆内单精子注射后的极体(PBs),结果发现,移植来自优倍卵母细胞的胚胎并不会提高活产率,但会减少胚胎移植和流产的次数。本研究旨在评估该研究试验的所有 PB 结果,并确定染色体异常的类型和最常受影响的染色体。ESTEEM试验获取了接受PGT-A的组群中第一个(PB1)和第二个(PB2)PB的活检结果,并使用阵列比较基因组杂交(aCGH)对其进行了分析。共有 693 对 PB 得到了完整的结果,其中包括 676 个确认的受精卵细胞。本文报告了这些配对的染色体分离情况,包括可能的内在机制。为了评估 aCGH 程序的可靠性,我们使用新一代测序技术(NGS)重新分析了来自一个中心的 72 对 PB。胚胎根据形态分为 4 类:良好、一般、较差和退化。为评估染色体状态与胚胎质量之间的关系,以及研究组(PGT-A 与对照组)与胚胎质量之间的关系,进行了对比分析。共有 213/676 个卵母细胞为优倍体,413/676 个卵母细胞为非优倍体,而在剩余的 50 个卵母细胞中,PB1 中观察到的异常被 PB2 中的异常所补偿。共有 693 对 PB 报告了染色体数目,结果涉及 15 939 条染色体。在 461 对 PB 中,有 1162 条染色体(7.3%)在 PB1 和/或 PB2 中出现异常分离。染色体 22(16.7%)、16(16.6%)、19(14.4%)、21(13.7%)和 15(12.4%)的异常分离频率最高。异常分离与减数分裂 1(M1)中姐妹染色单体的过早分离(568 条;48.9%)、减数分裂 2(M2)中染色体的不分离或反向分离(417 条;35.9%)以及减数分裂 1 中的不分离(65 条;5.6%)相符。然而,有 112 条染色体的分离模式无法归类为导致卵母细胞非整倍体的 9 种已知机制中的一种。在分析的 1656 条染色体中,有 1650 条(99.6%)的 aCGH 和 NGS 在两个 PB 中都获得了一致性。预测为非整倍体的胚胎在第 3 天(调整比值比 [aOR],0.62;95% 置信区间 [CI],0.43-0.90)、第 4 天(aOR,0.15;95% CI,0.06-0.39)和第 5 天(aOR,0.28;95% CI,0.14-0.58)的质量评分明显较差。这项研究是迄今为止对两种 PB 中染色体拷贝数进行的最大规模的分析之一,它强调了染色体拷贝数经常出现无法解释的情况,突出了人们对造成卵母细胞非整倍体机制的认识存在差距。

One of the risk factors for preterm birth (PTB) is bacterial vaginosis (BV), a common, often asymptomatic, vaginal dysbiosis. The earlier BV is diagnosed based on gestational age, the higher the risk of PTB. The effectiveness of a screen-and-treat strategy for BV during pregnancy remains a source of debate. One meta-analyses, including 5 studies and 2346 patients, showed a benefit to screen and treat using clindamycin. Another, with 21 studies and 7847 patients, did not recommend BV screening but observed reductions in preterm delivery by 50% and miscarriages by 80%. In another systematic review, with 48 studies, there was varying accuracy across conventional screening tests for BV and suggested no or inconclusive efficacy in the treatment of asymptomatic BV in the general obstetric population and in those with a history of preterm delivery. Based on these studies, French and international organizations recommend against screening for BV with conventional diagnosis tools in low-risk populations. However, molecular diagnostic tools have been shown to be more accurate in identifying vaginal microbiota than conventional tools, such as clinical diagnosis based on Amsel or Nugent criteria. Molecular tools have been shown to provide an objective, reproducible, quantitative diagnosis of BV, identifying emergent pathogen species, such as Atopobium vaginae (now known as Fannyhessea vaginae). To date, no randomized studies have been conducted to assess the impact of molecular tools on a screen-and-treat intervention to BV. The aim of this study was to assess whether a screen-and-treat intervention using a molecular diagnostic tool is cost-effective in reducing the rate of PTB. The AuTop Trial was a prospective, open-label superiority trial conducted in 19 French maternity hospitals from March 9, 2015, to December 18, 2017. Included were adult women in early pregnancy (<20 weeks of gestation), with no history of PTB or late abortion and no major risk factors for prematurity. Excluded were patients who had extrauterine pregnancy or nonprogressive pregnancy, or were treated with antibiotics a week before inclusion in the study. Women were randomly assigned 1:1 to undergo molecular screening and treatment (intervention group) or receive usual care (control group). The intervention group was asked to self-collect vaginal swabs and return them within 15 days of collection for each month until 28 weeks of gestation. If BV was detected, treatment with azithromycin (1 g repeated after 48 hours) or amoxicillin (2 g/d for 7 days) was provided within 48 hours. A molecular biology-based rapid diagnostic tool designed for point-of-care testing was developed using real-time polymerase chain reaction assays to quantify DNA levels of A. vaginae. The tool's specificity, sensitivity, positive predictive value, and negative predicative value of the tool were 99%, 95%, 95%, and 99%, respectively, compared with other diagnostic techniques. The control group received usual ca
早产(PTB)的风险因素之一是细菌性阴道病(BV),这是一种常见的、通常无症状的阴道菌群失调。根据孕龄越早诊断出细菌性阴道病,发生早产的风险就越高。孕期 BV 筛查和治疗策略的有效性仍存在争议。一项包括 5 项研究和 2346 名患者的荟萃分析表明,使用克林霉素进行筛查和治疗是有益的。另一项包括 21 项研究和 7847 名患者的荟萃分析不建议进行 BV 筛查,但观察到早产率降低了 50%,流产率降低了 80%。在另一项包含 48 项研究的系统性综述中,BV 传统筛查测试的准确性各不相同,并表明在普通产科人群和有早产史的人群中治疗无症状 BV 没有效果或效果不确定。基于这些研究,法国和国际组织建议不要在低风险人群中使用传统诊断工具筛查 BV。然而,分子诊断工具在确定阴道微生物群方面比传统工具(如基于 Amsel 或 Nugent 标准的临床诊断)更准确。分子诊断工具已被证明可对 BV 进行客观、可重复的定量诊断,并能确定新出现的病原体种类,如 Atopobium vaginae(现称为 Fannyhessea vaginae)。迄今为止,尚未进行过随机研究来评估分子工具对 BV 筛查和治疗干预的影响。本研究的目的是评估使用分子诊断工具进行筛查和治疗干预在降低 PTB 发病率方面是否具有成本效益。AuTop试验是一项前瞻性、开放标签的优越性试验,于2015年3月9日至2017年12月18日在法国19家妇产医院进行。试验纳入了早期妊娠(妊娠<20周)的成年女性,她们没有PTB或晚期流产史,也没有早产的主要风险因素。排除宫外孕或非进展性妊娠的患者,或在纳入研究前一周接受过抗生素治疗的患者。妇女按 1:1 随机分配接受分子筛查和治疗(干预组)或接受常规护理(对照组)。干预组要求妇女自行采集阴道拭子,并在采集后 15 天内交回,直至妊娠 28 周。如果检测到 BV,则在 48 小时内使用阿奇霉素(1 克,48 小时后重复使用)或阿莫西林(2 克/天,7 天)进行治疗。利用实时聚合酶链反应测定法,开发出了一种基于分子生物学的快速诊断工具,设计用于护理点检测,以量化阴道杆菌的 DNA 含量。与其他诊断技术相比,该工具的特异性、灵敏度、阳性预测值和阴性预测值分别为 99%、95%、95% 和 99%。对照组接受常规护理,未对 BV 进行系统筛查。共有 6671 名妇女被 1:1 随机分配到干预组(n = 3333)或对照组(n = 3338)。纳入干预组和对照组的孕妇中,共有 3438 名为单胎妊娠,其中干预组 1671 名,对照组 1767 名。在意向治疗分析中,干预组和对照组的 PTB 发生率没有下降(分别为 3.8% vs 4.6%;风险比为 0.83;95% 置信区间 [CI],0.66-1.05;P = 0.12)。每位妇女的平均干预成本为 203.60 欧元(218.00 美元)。干预组与对照组的总费用无明显差异(3344.30 欧元 [3580.50 美元] vs 3272.90 欧元 [3504.10 美元])。此外,没有证据表明干预策略优于常规护理。然而,在无子宫亚组中,干预组的 PTB 数量(3.6%;95% CI,2.9-4.6)显著低于对照组(5.9%,95% CI,4.8-7.2),且成本无显著性差异。总之,用于筛查和治疗 BV 的分子诊断工具并未显著降低 PTB 的风险。虽然在总体人群中未发现明显的获益,但使用分子工具进行筛查和治疗的策略在减少无阴道分娩的孕妇中发生阴道侧切胆管炎方面比常规护理更有效。

Although cell-free DNA (cfDNA) prenatal screening is widely used and has high sensitivity and specificity, there are circumstances in which the screening does not provide an interpretable result. Although this is relatively uncommon, it happens enough that clinical implications and potential reasons for follow-up should be studied and assessed. This study was designed to evaluate outcomes for pregnancies with nonreportable results on cfDNA screening tests. This study was a secondary analysis of the data from a multicenter prospective observational study of cfDNA screening for aneuploidy and 22q11.2 deletion syndrome. All patients were tested for trisomies 13, 18, and 21, as well as the 22q11.2 deletion syndrome, and all patients had confirmatory testing on the newborns in addition to collecting obstetric and perinatal outcomes. Inclusion criteria were women older than 18 years and at greater than 9 weeks of gestation with a singleton pregnancy. Exclusion criteria were having received cfDNA screening results before enrollment, organ transplant, ovum donation, vanishing twin, or being unwilling to provide a newborn sample. The primary outcome was the rate of adverse obstetrical and perinatal outcomes, including aneuploidy; preterm birth at less than 28, 34, or 37 weeks' gestation; preeclampsia; small for gestational age birth; and a composite outcome that included preterm birth before 37 weeks, preeclampsia, stillbirth at greater than 20 weeks, and small for gestational age. Final analyses included 17,851 individuals who had cfDNA screening, confirmatory genetic testing on the newborn, and obstetrical and perinatal outcomes recorded. Nonreportable results were found in 602 individuals (3.4%) after the first draw, with 32.2% of these due to low fetal fraction. Another third of the cohort had patterns where the risk of aneuploidy was uninterpretable but with an adequate fetal fraction, and in the final third, the fetal fraction could not be measured. Of the original 602 cases of nonreportable findings, 427 had a second draw, with 112 of these (26.2%) again having nonreportable results. There were no significant differences in baseline characteristics of age and parity for those with successful versus nonreportable test results; gestational age was significantly higher in individuals with nonreportable results (14.4 vs 13.4 weeks, P < 0.001), as was body mass index (26.2 vs 31.3), and the rate of chronic hypertension (4.0% vs 9.7%). In this cohort, there were 133 genetically confirmed trisomies, with 100 fetuses with trisomy 21, 18 individuals with trisomy 18, and 15 individuals with trisomy 13. Overall, the rate of aneuploidy was 1.7% in individuals with nonreportable results, versus 0.7% in those with reported results (P = 0.013; adjusted odds ratio [aOR] 2.1; 95% confidence interval [CI], 1.1–4.0). Rates of preterm birth were also higher in those with nonreportable test results, with delivery at less than 34 weeks at 1.5% in those with a test
尽管无细胞 DNA(cfDNA)产前筛查已被广泛应用,并具有较高的灵敏度和特异性,但在某些情况下,筛查并不能提供可解释的结果。虽然这种情况比较少见,但也足以说明其临床影响和随访的潜在原因,因此应该对其进行研究和评估。本研究旨在评估因 cfDNA 筛查检测结果无法报告而导致的妊娠结局。本研究是对一项针对非整倍体和 22q11.2 缺失综合征的 cfDNA 筛查的多中心前瞻性观察研究的数据进行的二次分析。所有患者都接受了 13、18 和 21 三体以及 22q11.2 缺失综合征的检测,除了收集产科和围产期结果外,所有患者的新生儿都接受了确证检测。纳入标准是年龄超过 18 岁、妊娠超过 9 周且为单胎妊娠的女性。排除标准为:入组前已收到 cfDNA 筛查结果、器官移植、卵子捐赠、消失的双胞胎或不愿提供新生儿样本。主要结果是不良产科和围产期结果的发生率,包括非整倍体;妊娠不足 28 周、34 周或 37 周的早产;子痫前期;小于胎龄儿;以及包括 37 周前早产、子痫前期、大于 20 周死胎和小于胎龄儿的综合结果。最终分析包括了 17851 名接受 cfDNA 筛查、新生儿确证基因检测以及产科和围产期结果记录的个体。在首次抽血后发现有 602 人(3.4%)无法报告结果,其中 32.2% 是由于胎儿分数过低。另外三分之一的样本中,非整倍体风险无法解读,但胎儿分数足够;最后三分之一的样本中,胎儿分数无法测量。在原有的 602 例无法报告结果的病例中,有 427 例进行了第二次抽血,其中 112 例(26.2%)再次出现无法报告结果的情况。成功与未报告检测结果者在年龄和胎次等基线特征方面无明显差异;未报告检测结果者的妊娠年龄(14.4 周 vs 13.4 周,P < 0.001)、体重指数(26.2 vs 31.3)和慢性高血压发病率(4.0% vs 9.7%)均明显高于成功者。该队列中有 133 例经基因证实的三体综合征,其中 100 例为 21 三体综合征胎儿,18 例为 18 三体综合征胎儿,15 例为 13 三体综合征胎儿。总体而言,未报告结果的非整倍体率为 1.7%,而报告结果的非整倍体率为 0.7%(P = 0.013;调整赔率比 [aOR] 2.1;95% 置信区间 [CI],1.1-4.0)。未报告检测结果者的早产率也较高,在有检测结果者中,34 周以下分娩的比例为 1.5%,在有一次未报告检测结果者中为 4.6%,在有第二次未报告检测结果者中为 6.9%(aOR,分别为 2.2 和 2.7;95% CI,分别为 1.4-3.4 和 1.2-6.0)。子痫前期的发病率也呈类似趋势,从报告结果时的 3.9%上升到报告一次未报告结果时的 9.4%,报告两次未报告结果时的 16.8%(aOR,分别为 1.4 和 2.0;95% CI,分别为 1.0-1.9 和 1.1-3.7)。未报告结果的孕妇活产几率明显降低(aOR,0.20;95% CI,0.13-0.30),第二次未报告检测结果后,活产几率下降幅度更大(aOR,0.11;95% CI,0.06-0.23)。该研究发现,无法报告的 cfDNA 筛查结果与非整倍体、早产和子痫前期风险的增加有关,第二次检测失败后风险呈梯度增加。此外,文献中关于 cfDNA 水平改变者产科并发症的研究结果相互矛盾,而且大多数研究主要集中在可预测未报告结果的特征上,而不是与未报告结果相关的结果上。这些研究结果可以为临床医生提供一些信息,帮助他们更好地照顾那些检测结果无法报告的患者;未来的研究应侧重于更全面地了解与无法报告的检测结果相关的不良后果,以最大限度地提高临床医生的能力。进一步的研究还应关注特定人群或诊断,以了解不同人群是否存在根本性差异。

(Abstracted from Lancet Oncol 2023;24:P1109–P1118) Although the 5-year survival of patients with advanced ovarian cancer has improved, overall survival at 10 years remains approximately 13%. Hyperthermic intraperitoneal chemotherapy (HIPEC) involves the delivery of chemotherapeutic agents directly into the peritoneum in combination with hyperthermia, which enhances penetration and increases sensitivity to platinum compounds by inducing a transient state of homologous recombination deficiency.

Several medications have been used to achieve medical abortion in the first trimester of pregnancy. The most commonly used is the combination of mifepristone and misoprostol; however, different doses and routes of administration have been proposed. The aim of this study was to summarize published data on the effectiveness, adverse effects, and acceptability of the various combinations of mifepristone and misoprostol in medical abortion protocols in the first trimester of pregnancy. This was a comprehensive review, synthesizing the findings of the literature on the current use of mifepristone and misoprostol for first-trimester abortion. The combination of mifepristone and misoprostol seems to be more effective than misoprostol alone. Regarding the dosages and routes, mifepristone is administered orally, and the optimal dose is 200 mg. The route of administration of misoprostol varies; the sublingual and buccal routes are more effective; however, the vaginal route (800 μg) is associated with fewer adverse effects. Finally, the acceptability rates did not differ significantly. Different schemes for first-trimester medical abortion have been described so far. Future research needs to focus on identifying the method that offers the best trade-off between efficacy and safety in first-trimester medical abortion. Obstetricians and gynecologists, family physicians After participating in this activity, the learner should be better able to discuss available combinations of mifepristone and misoprostol for first-trimester medical abortion; describe the recommended doses of misoprostol for first-trimester medical abortion; and assess the adverse effects caused by misoprostol when administered by different routes.
在妊娠头三个月,有多种药物可用于药物流产。最常用的是米非司酮和米索前列醇的复方制剂,但也提出了不同的剂量和给药途径。 本研究旨在总结已发表的有关妊娠头三个月药物流产方案中米非司酮和米索前列醇不同组合的有效性、不良反应和可接受性的数据。 这是一篇全面的综述,综合了目前使用米非司酮和米索前列醇进行妊娠头三个月人工流产的文献研究结果。 米非司酮和米索前列醇联合使用似乎比单独使用米索前列醇更有效。关于剂量和给药途径,米非司酮为口服给药,最佳剂量为 200 毫克。米索前列醇的给药途径各不相同;舌下和口腔给药途径更有效,但阴道给药途径(800 微克)的不良反应较少。最后,接受率没有明显差异。 迄今为止,已介绍了不同的第一胎药物流产方案。未来的研究需要重点确定在第一胎药物流产的有效性和安全性之间进行最佳权衡的方法。 妇产科医生、家庭医生 参加本活动后,学习者应能更好地讨论米非司酮和米索前列醇用于第一胎药物流产的可用组合;描述第一胎药物流产中米索前列醇的推荐剂量;以及评估米索前列醇通过不同途径给药时引起的不良反应。

Induction of labor (IOL) is a common obstetric intervention. Augmentation of labor and active management of the second stage is frequently required in obstetric practice. However, techniques around labor and induction management vary widely. Evidence-based practice regarding induction and labor management can reduce birth complications such as infection and hemorrhage and decrease rates of cesarean delivery. To review existing evidence on IOL and labor management strategies with respect to preparing for induction, cervical ripening, induction and augmentation, and second stage of labor techniques. Review of recent original research, review articles, and guidelines on IOL using PubMed (2000–2022). Preinduction, pelvic floor training and perineal massage reduce postpartum urinary incontinence and perineal trauma, respectively. Timely membrane sweeping (38 weeks) can promote spontaneous labor and prevent postterm inductions. Outpatient Foley bulb placement in low-risk nulliparous patients with planned IOL reduces time to delivery. Inpatient Foley bulb use beyond 6 to 12 hours shows no benefit. When synthetic prostaglandins are indicated, vaginal misoprostol should be preferred. For nulliparous patients and those with obesity, oxytocin should be titrated using a high-dose protocol. Once cervical dilation is complete, pushing should begin immediately. Warm compresses and perineal massage decrease risk of perineal trauma. Several strategies exist to assist in successful IOL and promote vaginal delivery. Evidence-based strategies should be used to improve outcomes and decrease risk of complications and cesarean delivery. Recommendations should be shared across interdisciplinary team members, creating a model that promotes safe patient care. Obstetricians and gynecologists, family physicians Discuss the current evidence and best practices regarding prelabor interventions to improve delivery outcomes; describe evidence-based methods of cervical ripening; outline data-driven practices to progress induction; and explain methods to improve birth outcomes and reduce risks in the second stage of labor.
引产(IOL)是一种常见的产科干预措施。产科实践中经常需要对第二产程进行扩产和积极管理。然而,有关分娩和引产管理的技术差别很大。以证据为基础的引产和分娩管理可减少感染和出血等分娩并发症,并降低剖宫产率。 回顾有关引产准备、宫颈成熟、引产和扩宫以及第二产程技术的 IOL 和分娩管理策略的现有证据。 使用 PubMed(2000-2022 年)对有关 IOL 的最新原始研究、评论文章和指南进行回顾。 引产前的盆底训练和会阴按摩可分别减少产后尿失禁和会阴创伤。及时清宫(38 周)可促进自然分娩并防止过期引产。对计划进行人工晶体植入术的低风险无阴道患者进行门诊福来球置入术可缩短分娩时间。住院患者使用 Foley 灯泡超过 6 至 12 小时后就没有益处了。当需要使用合成前列腺素时,应首选阴道米索前列醇。对于无子宫和肥胖的患者,应使用大剂量方案滴注催产素。宫颈扩张完成后,应立即开始用力。热敷和会阴按摩可降低会阴创伤的风险。 有几种策略可以帮助人工晶体植入术成功并促进阴道分娩。应采用基于证据的策略来改善结果,降低并发症和剖宫产的风险。跨学科团队成员应共享建议,创建一个促进患者安全护理的模式。 妇产科医生、家庭医生 讨论有关产前干预以改善分娩结局的现有证据和最佳实践;描述以证据为基础的宫颈成熟方法;概述以数据为导向的促进引产的实践;解释改善分娩结局和降低第二产程风险的方法。
