  • 文章类型: Journal Article
    雌性果蝇交配会导致中肠肥大和寿命缩短,这些作用被药物米非司酮阻断。Eip75B是先前报道的对果蝇寿命具有多效性作用的转录因子。因为Eip75B无效突变是致命的,需要条件系统和/或部分敲低来研究成人的Eip75B效应。先前的研究表明,Eip75B是成年中肠细胞增殖所必需的。为了测试Eip75B在介导交配和米非司酮的寿命效应中的可能作用,采用了基于三部分FLP重组酶的条件系统,该系统提供了遗传背景的控制。通过短暂的热脉冲在三龄幼虫中诱导Hsp70-FLP转基因的表达。FLP重组酶催化Actin5C-GAL4转基因的重组和活化。GAL4转录因子进而激活UAS-Eip75B-RNAi转基因的表达。通过交配时中肠肥大的丧失证实了Eip75B活性的抑制,并且消除了交配和米非司酮的寿命效应。此外,消除了米非司酮对鸡蛋生产的负面影响。数据表明,Eip75B介导交配和米非司酮对雌性中肠肥大的影响,产蛋,和寿命。
    Mating in female Drosophila melanogaster causes midgut hypertrophy and reduced lifespan, and these effects are blocked by the drug mifepristone. Eip75B is a transcription factor previously reported to have pleiotropic effects on Drosophila lifespan. Because Eip75B null mutations are lethal, conditional systems and/or partial knock-down are needed to study Eip75B effects in adults. Previous studies showed that Eip75B is required for adult midgut cell proliferation in response to mating. To test the possible role of Eip75B in mediating the lifespan effects of mating and mifepristone, a tripartite FLP-recombinase-based conditional system was employed that provides controls for genetic background. Expression of a Hsp70-FLP transgene was induced in third instar larvae by a brief heat pulse. The FLP recombinase catalyzed the recombination and activation of an Actin5C-GAL4 transgene. The GAL4 transcription factor in turn activated expression of a UAS-Eip75B-RNAi transgene. Inhibition of Eip75B activity was confirmed by loss of midgut hypertrophy upon mating, and the lifespan effects of both mating and mifepristone were eliminated. In addition, the negative effects of mifepristone on egg production were eliminated. The data indicate that Eip75B mediates the effects of mating and mifepristone on female midgut hypertrophy, egg production, and lifespan.

    子宫平滑肌瘤,或肌瘤,是常见的良性妇科肿瘤,影响许多妇女在生育年龄。虽然手术切除长期以来一直是纤维瘤治疗的金标准,药理学管理,包括孕激素受体调节剂,如米非司酮(RU486),由于手术方法的减少,引起了人们的注意。然而,关于米非司酮有效性的研究明显缺乏,在相同的。这项研究旨在评估米非司酮在减少子宫平滑肌瘤大小和减轻相关症状方面的安全性和有效性。
    前瞻性地进行,这项研究招募了20名绝经前妇女,18岁或以上,孟买纳纳瓦蒂·马克斯超级专科医院,马哈拉施特拉邦,印度。参与者是根据具体的入选标准选择的,包括超声证实的至少一个最小直径为2.5厘米的子宫肌瘤的存在。参与者的平均年龄为39.75岁,平均BMI为27.58kg/m2。
    研究发现米非司酮使子宫体积显著减少75%,血红蛋白水平从最初的9gm/dL大幅改善至6个月后的12.51gm/dL。疼痛强度,使用视觉模拟量表(VAS)评分进行评估,从基线逐渐下降到三个月,所有20例患者报告到6个月时完全没有盆腔疼痛。
    这项前瞻性研究强调了米非司酮作为有效减少子宫肌瘤体积的非手术方法的承诺,提高血红蛋白水平,减轻患者的子宫失血。
    UNASSIGNED: Uterine leiomyomas, or fibroids, are prevalent benign gynecological tumors affecting many women during their reproductive years. While surgical excision has long been the gold standard for fibroid treatment, the pharmacological management, including progesterone receptor modulators like mifepristone (RU 486), has garnered attention due to the reduced surgical approaches. However, there is a notable paucity of research on the effectiveness of mifepristone, on the same. This study seeks to evaluate the safety and efficacy of mifepristone in reducing uterine leiomyoma size and alleviating associated symptoms.
    UNASSIGNED: Conducted prospectively, the study enrolled 20 pre-menopausal women, aged 18 years or older, from Nanavati Max Super Speciality Hospital Mumbai, Maharashtra, India. Participants were selected based on specific inclusion criteria, including the presence of at least one uterine myoma with a minimum diameter of 2.5 cm as confirmed by ultrasound. Participants had an average age of 39.75 years and an average BMI of 27.58 kg/m2.
    UNASSIGNED: The study found that mifepristone significantly reduced uterine volume by 75%, with hemoglobin levels substantially improving from 9 gm/dL initially to 12.51 gm/dL after six months. Pain intensity, assessed using the Visual Analog Scale (VAS) score, gradually decreased from baseline to three-month, with all 20 patients reporting the complete absence of pelvic pain by six months.
    UNASSIGNED: This prospective study highlights mifepristone\'s promise as a non-surgical approach to effectively reduce uterine fibroid volume, improve hemoglobin levels, and mitigate uterine blood loss in patients.

    本研究共纳入100例足月妊娠患者。口服200毫克米非司酮,根据48h时Bishop评分的改善情况评估米非司酮的疗效。如果48h后Bishop评分改善不足,额外的宫颈内给药用于诱导。
    在100名患者中,50名妇女在服用米非司酮后阴道分娩。24例患者在服用米非司酮后48小时内阴道分娩。我们观察到69%的参与者在48小时Bishop’s得分为6分或以上。50名患者需要额外的子宫颈素。30名参与者接受了剖宫产。米非司酮后0h的平均改良Bishop评分为1.87,48h后改善为6.92。在P值<0.005的平均Bishop评分下发现统计学上的显著差异。
    在我们的研究中,我们发现米非司酮是一种安全有效的宫颈成熟剂,用于足月妊娠宫颈不良。它具有良好的耐受性,并导致宫颈明显成熟,Bishop评分改善有利于阴道分娩。
    UNASSIGNED: Modern-day obstetrics recommend induction of labor by medical or mechanical methods where continuation of pregnancy causes detrimental effect to the health of mother or fetus. One of the prerequisites for successful vaginal delivery includes a favorable or ripe cervix. We undertook the present study to find out the safety and efficacy of mifepristone for pre-induction cervical ripening and its effect on Bishop\'s score in term pregnancy.
    UNASSIGNED: A total of 100 patients with term pregnancy were enrolled for this study. 200 mg of mifepristone was administered orally, and efficacy of mifepristone was assessed based on improvement in modified Bishop\'s score at 48 h. If there was inadequate improvement in Bishop\'s score after 48 h, additional intracervical cerviprime was administered for induction.
    UNASSIGNED: Out of 100 patients, 50 women delivered vaginally after administration of mifepristone. Twenty-four patients delivered vaginally within 48 h of administration of mifepristone. We observed the Bishop\'s score of  6 or more at 48 h in 69% participants. Fifty patients required additional intracervical cerviprime. Thirty participants underwent cesarean section. Mean Modified Bishop\'s score at 0 h was 1.87 and improved to 6.92 after 48 h after mifepristone. A statistically significant difference was found with mean Bishop\'s score with p value < 0.005.
    UNASSIGNED: In our study, we found that mifepristone is a safe and effective cervical ripening agent in term pregnancy with unfavorable cervix. It is well tolerated and leads to significant cervical ripening with improvement in Bishop\'s score favoring vaginal delivery.

    睡眠和免疫内分泌系统之间的联系是公认的,但是这种关系的性质还没有得到很好的理解。睡眠碎片诱导外周组织和大脑的促炎反应,但它也激活下丘脑-垂体-肾上腺(HPA)轴,释放糖皮质激素(GC)(人类皮质醇和小鼠皮质酮)。尚不清楚糖皮质激素的这种快速释放是否在短期内增强或抑制炎症反应。这项研究的目的是确定阻断或抑制糖皮质激素活性是否会影响急性睡眠碎片(ASF)的炎症反应。雄性C57BL/6J小鼠腹膜内注射0.9%NaCl(载体1),metyrapone(一种糖皮质激素合成抑制剂,溶解在车辆1中),2%乙醇在聚乙二醇(载体2),或者米非司酮(一种糖皮质激素受体拮抗剂,溶解在媒介物2中)在ASF开始前10分钟或无睡眠碎片(NSF)。24小时后,样本是从大脑(前额叶皮层,下丘脑,海马体)和外周(肝脏,脾,脾心,和附睾白色脂肪组织(EWAT))。测量促炎基因表达(TNF-α和IL-1β),然后进行基因表达分析。美替酮治疗影响了ASF期间某些外周组织的促炎细胞因子基因表达,但不是在大脑里.更具体地说,甲吡酮治疗抑制ASF期间EWAT中IL-1β的表达,这意味着GC的促炎作用。然而,在心脏组织中,甲吡酮治疗可增加ASF小鼠的TNF-α表达,提示GC的抗炎作用。米非司酮治疗比甲吡酮产生更显著的结果,在ASF期间减少肝脏(仅NSF小鼠)和心脏组织中的TNF-α表达,表明有促炎作用。相反,在ASF小鼠的脾脏中,米非司酮增加促炎细胞因子(TNF-α和IL-1β),表现出抗炎作用。此外,不管睡眠碎片,米非司酮增加心脏促炎细胞因子基因表达(IL-1β),前额叶皮质(IL-1β),和下丘脑(IL-1β)。结果为皮质酮的促炎和抗炎功能提供了混合证据,以调节急性睡眠不足的炎症反应。
    The association between sleep and the immune-endocrine system is well recognized, but the nature of that relationship is not well understood. Sleep fragmentation induces a pro-inflammatory response in peripheral tissues and brain, but it also activates the hypothalamic-pituitary-adrenal (HPA) axis, releasing glucocorticoids (GCs) (cortisol in humans and corticosterone in mice). It is unclear whether this rapid release of glucocorticoids acts to potentiate or dampen the inflammatory response in the short term. The purpose of this study was to determine whether blocking or suppressing glucocorticoid activity will affect the inflammatory response from acute sleep fragmentation (ASF). Male C57BL/6J mice were injected i.p. with either 0.9% NaCl (vehicle 1), metyrapone (a glucocorticoid synthesis inhibitor, dissolved in vehicle 1), 2% ethanol in polyethylene glycol (vehicle 2), or mifepristone (a glucocorticoid receptor antagonist, dissolved in vehicle 2) 10 min before the start of ASF or no sleep fragmentation (NSF). After 24 h, samples were collected from brain (prefrontal cortex, hypothalamus, hippocampus) and periphery (liver, spleen, heart, and epididymal white adipose tissue (EWAT)). Proinflammatory gene expression (TNF-α and IL-1β) was measured, followed by gene expression analysis. Metyrapone treatment affected pro-inflammatory cytokine gene expression during ASF in some peripheral tissues, but not in the brain. More specifically, metyrapone treatment suppressed IL-1β expression in EWAT during ASF, which implies a pro-inflammatory effect of GCs. However, in cardiac tissue, metyrapone treatment increased TNF-α expression in ASF mice, suggesting an anti-inflammatory effect of GCs. Mifepristone treatment yielded more significant results than metyrapone, reducing TNF-α expression in liver (only NSF mice) and cardiac tissue during ASF, indicating a pro-inflammatory role. Conversely, in the spleen of ASF-mice, mifepristone increased pro-inflammatory cytokines (TNF-α and IL-1β), demonstrating an anti-inflammatory role. Furthermore, irrespective of sleep fragmentation, mifepristone increased pro-inflammatory cytokine gene expression in heart (IL-1β), pre-frontal cortex (IL-1β), and hypothalamus (IL-1β). The results provide mixed evidence for pro- and anti-inflammatory functions of corticosterone to regulate inflammatory responses to acute sleep loss.

    背景:在印度,使用米非司酮和米索前列醇的药物流产可在妊娠63天。这占该国所有堕胎的67.5%。我们进行了评估,以确定药物流产药物的可用性,特别是组合包,在印度。
    方法:我们在国家一级应用了世界卫生组织景观评估协议。评估协议包括对现有可用性框架的五步调整,包括在线数据收集,案头审查,国家一级的关键线人访谈,和分析,以确定障碍和机会,以提高医疗流产的可用性。评估于2021年8月至3月间进行。
    结果:药物流产药物被列入国家基本药物清单,并在印度有处方。评估确定了由35家制造商开发的42种组合包装产品。药物流产药物的质量由国家当局监管;但是随着健康移交给各州,有显著的州际差异。这在整个融资过程中都可以看到,采购,制造,和药物流产药物分发前质量保证的监测机制。有必要加强供应链系统,确保训练有素的提供者的一致可用性,并提高社区对使用药物流产药物进行早期流产的认识,在评估时。
    结论:存在提高药物流产药物的可用性和质量的机会。例如,统一执行监管标准,在制造过程中更加重视质量保证,以及各州采购和供应链系统的标准化。需要对提供者进行药物流产的定期在职培训。最后,需要在证据传播和社区参与方面进行创新,以了解最近修订的堕胎法。
    药物流产在印度很流行,并受益于自由的法律背景。重要的是要了解该国优质流产药物的可用性。使用世界卫生组织国家评估协议和药物流产药物的可用性框架,我们从供应到需求检查了这些药物的可用性。我们利用这些信息来确定增加质量保证的药物流产的机会。我们发现,药物流产的背景因各州而异。加强采购和供应链管理,应在国家一级更加重视质量保证和制造业监管。还需要培训,以增加提供者对最新国家准则和法律的了解,以确保尊重和以人为本的服务。最后,应该让公众了解药物流产是一种安全有效的选择,尤其是早期流产。
    BACKGROUND: Medical abortion with mifepristone and misoprostol can be provided up to 63 days\' gestation in India. This accounts for 67.5 percent of all abortions in the country. We conducted an assessment to determine the availability of medical abortion medicines, specifically the combi-pack, in India.
    METHODS: We applied the World Health Organization landscape assessment protocol at the national level. The assessment protocol included a five-step adaptation of an existing availability framework, including online data collection, desk review, country-level key informant interviews, and an analysis to identify barriers and opportunities to improve medical abortion availability. The assessment was conducted between August and March 2021.
    RESULTS: Medicines for medical abortion are included in the national essential drug list and available with prescription in India. The assessment identified 42 combi-pack products developed by 35 manufacturers. The quality of medical abortion medicines is regulated by national authorities; but as health is devolved to states, there are significant inter-state variations. This is seen across financing, procurement, manufacturing, and monitoring mechanisms for quality assurance of medical abortion medicines prior to distribution. There is a need to strengthen supply chain systems, ensure consistent availability of trained providers and build community awareness on use of medical abortion medicines for early abortions, at the time of the assessment.
    CONCLUSIONS: Opportunities to improve availability and quality of medical abortion medicines exist. For example, uniform implementation of regulatory standards, greater emphasis on quality-assurance during manufacturing, and standardizing of procurement and supply chain systems across states. Regular in-service training of providers on medical abortion is required. Finally, innovations in evidence dissemination and community engagement about the recently amended abortion law are needed.
    Medical abortion is popular in India and benefits from a liberal legal context. It is important to understand the availability of quality abortion medicines in the country. Using the World Health Organization country assessment protocol and availability framework for medical abortion medicines we examined the availability of these medicines from supply to demand. We used this information to identify opportunities for increasing availability of quality-assured medical abortion medicines. We found that the context for medical abortion varies across states. Strengthening procurement and supply chain management, with a greater emphasis on quality-assurance and regulation of manufacturing should be instituted at the state-level. Training is also needed to increase provider knowledge of the latest national guidelines and laws to ensure respectful and person-centered services. Finally, the public should be informed about medical abortion as a safe and effective choice, especially for early abortions.

    背景:尽管它们对降低孕产妇死亡率很重要,关于获得米非司酮的信息,米索前列醇,东地中海地区的避孕药物有限。
    方法:一种标准化评估工具,用于测量获得米非司酮的情况,米索前列醇,世卫组织基本药物清单(EML)中的避孕药物在东地中海区域的八个国家(阿富汗,伊拉克,黎巴嫩,利比亚,摩洛哥,巴勒斯坦,巴基斯坦,和索马里)在2020-2021年之间。评估的重点是五项获取措施:1)将药物纳入国家计划生育指南;2)将药物纳入综合堕胎护理指南;3)将药物纳入国家基本药物清单;4)药物注册;5)米非司酮的采购和预测,米索前列醇,和避孕药。对这八项国家评估的结果进行了描述性分析。
    结果:只有黎巴嫩和巴基斯坦在其国家计划生育指南中纳入了WHO-EML的所有12种避孕药具。只有阿富汗和黎巴嫩在堕胎后护理指南中包括米非司酮和米非司酮-米索前列醇组合,但这些药物不包括在他们的国家EMLs。利比亚和索马里缺乏药品注册的国家监管机构。大多数避孕药包括在黎巴嫩的国家EMLs中,摩洛哥和巴基斯坦已注册。米索前列醇被列入EML,并在六个国家注册(阿富汗,伊拉克,黎巴嫩,摩洛哥,巴勒斯坦,和巴基斯坦)。然而,只有三个国家采购了米索前列醇(伊拉克,摩洛哥,和索马里)。
    结论:这些发现可以指导旨在提高米非司酮可用性的努力,米索前列醇,以及东地中海地区的避孕药物。机会包括扩大国家EML,包括米非司酮的更多选择,米索前列醇,并加强注册和采购制度,以确保这些药物的可获得性是国家法律和文化上可接受的。
    确保获得米非司酮,米索前列醇,避孕药物对改善妇女健康至关重要,更具体地说,降低产妇死亡率,改善东地中海区域妇女的性健康和生殖健康。这项研究的目的是分析国家评估的结果,以获取有关执行相关政策和程序的信息。这些是确保获得米非司酮的政策,米索前列醇,和研究中包括的八个东地中海区域国家在公共部门的避孕药物(阿富汗,伊拉克,利比亚,黎巴嫩,摩洛哥,巴勒斯坦,巴基斯坦,和索马里)。评估在2020年至2021年之间完成。我们发现,大多数国家并没有在其国家计划生育指南中纳入世卫组织基本药物清单(EML)中的所有12种避孕药具。没有任何国家制定了国家堕胎护理指南,也没有将米非司酮(单独或与米索前列醇联合使用)纳入国家EML。利比亚和索马里缺乏药品注册的国家监管机构。大多数避孕药包括在黎巴嫩的国家EMLs中,摩洛哥和巴基斯坦已注册。米索前列醇被列入EML-并在六个国家注册(阿富汗,伊拉克,黎巴嫩,摩洛哥,巴勒斯坦,和巴基斯坦)然而,只有三个国家采购了米索前列醇(伊拉克,摩洛哥,和索马里)。我们的发现为米非司酮的使用提供了系统级障碍的证据,米索前列醇,和避孕药(例如,缺乏关于EML的指导方针或纳入,缺乏注册和采购),可以支持加强制药部门的政策和宣传努力,以更好地确保米非司酮的供应,米索前列醇,根据国家法律和现行文化,在国家一级向育龄妇女提供避孕药具。
    BACKGROUND: Despite their importance in reducing maternal mortality, information on access to Mifepristone, Misoprostol, and contraceptive medicines in the Eastern Mediterranean Region is limited.
    METHODS: A standardized assessment tool measuring access to Mifepristone, Misoprostol, and contraceptive medicines included in the WHO essential medicines list (EML) was implemented in eight countries in the Eastern Mediterranean Region (Afghanistan, Iraq, Lebanon, Libya, Morocco, Palestine, Pakistan, and Somalia) between 2020-2021. The assessment focused on five access measures: 1) the inclusion of medicines in national family planning guidelines; 2) inclusion of medicines in comprehensive abortion care guidelines; 3) inclusion of medicines on national essential medicines lists; 4) medicines registration; and 5) procurement and forecasting of Mifepristone, Misoprostol, and contraceptive medicines. A descriptive analysis of findings from these eight national assessments was conducted.
    RESULTS: Only Lebanon and Pakistan included all 12 contraceptives that are enlisted in the WHO-EML within their national family planning guidelines. Only Afghanistan and Lebanon included mifepristone and mifepristone-misoprostol combination in post-abortion care guidelines, but these medicines were not included in their national EMLs. Libya and Somalia lacked a national regulatory authority for medicines registration. Most contraceptives included on the national EMLs for Lebanon, Morocco and Pakistan were registered. Misoprostol was included on the EMLs-and registered-in six countries (Afghanistan, Iraq, Lebanon, Morocco, Palestine, and Pakistan). However, only three countries procured misoprostol (Iraq, Morocco, and Somalia).
    CONCLUSIONS: These findings can guide efforts aimed at improving the availability of Mifepristone, Misoprostol, and contraceptive medicines in the Eastern Mediterranean Region. Opportunities include expanding national EMLs to include more options for Mifepristone, Misoprostol, and contraceptive medicines and strengthening the registration and procurement systems to ensure these medicines\' availability were permitted under national law and where culturally acceptable.
    Ensuring access to Mifepristone, Misoprostol, and contraceptive medicines is critical to improving women’s health, and more specifically reducing maternal mortality and improving women’s sexual and reproductive health in the Eastern Mediterranean Region.The aim of this study was to analyse findings from national assessments to capture information on the implementation of relevant policies and procedures. Those were the policies that ensure access to Mifepristone, Misoprostol, and contraceptive medicines in the public sector for the eight Eastern Mediterranean Region countries included in the study (Afghanistan, Iraq, Libya, Lebanon, Morocco, Palestine, Pakistan, and Somalia). The assessments were completed between 2020 and 2021.We found that most countries did not include all twelve contraceptives enlisted in the WHO essential medicines list (EML) in their national family planning guidelines. No country had developed a national abortion care guidelines nor included mifepristone (alone or in combination with misoprostol) on national EML. Libya and Somalia lacked a national regulatory authority for medicines registration. Most contraceptives included on the national EMLs for Lebanon, Morocco and Pakistan were registered. Misoprostol was included on the EMLs—and registered—in six countries (Afghanistan, Iraq, Lebanon, Morocco, Palestine, and Pakistan) yet, only three countries procured misoprostol (Iraq, Morocco, and Somalia).Our findings provide evidence on system-level barriers to availability of Mifepristone, Misoprostol, and contraceptive medicines (e.g., lack of guidelines or inclusion on EML, lack of registration and procurement) that can support policy and advocacy efforts to strengthen the pharmaceutical sector to better ensure availability of Mifepristone, Misoprostol, and contraceptive medicines to women in reproductive age at the country-level in accordance with the national law and prevailing culture.

    米非司酮-米索前列醇治疗药物流产和流产是安全有效的。本研究旨在评估早期存活或无存活妊娠药物终止后与后续手术干预相关的临床因素。
    这次回顾展,单中心研究纳入了2010年1月至2019年12月在台北医科大学接受药物流产的女性.共1561个科目,有1,080例可行妊娠和481例非可行妊娠,包括口服米非司酮600mg,然后在48小时后口服米索前列醇600mg。使用回归分析评估所有妊娠和医学终止妊娠的数据。主要结局是成功终止妊娠。
    在有生命和无生命的妇女中,药物流产的成功率相当(92.13%vs.92.93%)怀孕。除了保留的组织,与可行妊娠组相比,在非可行妊娠组中发现了更多具有超声检查结果的现有妊娠(29.4%vs.14.1%,p=0.011)。多因素分析显示,在所有纳入病例中,既往分娩是药物流产失败的独立危险因素。在有可行怀孕的女性中,胎龄较长[校正比值比(aOR):1.483,95%置信区间(CI):1.224~1.797,p<0.001]和既往剖宫产(aOR:2.177,95%CI:1.167~40.62,p=0.014)是药物流产失败的独立危险因素.剖宫产次数(aOR:1.448,95%CI:1.029-2.039,p=0.034)是无存活妊娠妇女药物流产失败的独立危险因素。
    这是第一项队列研究,旨在确定在进行早期药物引产的有存活或无存活妊娠的妇女中进行后续手术干预的危险因素。在有可行妊娠和无可行妊娠的妇女中,药物流产的成功率相当。既往分娩是药物流产失败的独立危险因素。对于有后续手术干预风险的女性,可能需要进行临床随访。
    UNASSIGNED: Mifepristone-misoprostol treatment for medical abortion and miscarriage are safe and effective. This study aimed to assess clinical factors associated with subsequent surgical intervention after medical termination of early viable or non-viable pregnancy.
    UNASSIGNED: This retrospective, single-center study included women who underwent medical abortion at Taipei Medical University between January 2010 and December 2019. A total of 1,561 subjects, with 1,080 viable and 481 non-viable pregnancies, who were treated with oral mifepristone 600 mg followed by misoprostol 600 mg 48 h later were included. Data of all pregnancies and medical termination of pregnancy were evaluated using regression analysis. The main outcome was successful termination of pregnancy.
    UNASSIGNED: The success rate of medical abortion was comparable in women with viable and non-viable (92.13% vs. 92.93%) pregnancies. Besides retained tissue, more existing pregnancies with ultrasonographic findings were found in the non-viable pregnancy group than in the viable pregnancy group (29.4% vs. 14.1%, p = 0.011). Multivariate analysis showed that previous delivery was an independent risk factor for failed medical abortion among all included cases. In women with viable pregnancy, longer gestational age [adjusted odds ratio (aOR): 1.483, 95% confidence interval (CI): 1.224-1.797, p < 0.001] and previous Cesarean delivery (aOR: 2.177, 95% CI: 1.167-40.62, p = 0.014) were independent risk factors for failed medical abortion. Number of Cesarean deliveries (aOR: 1.448, 95% CI: 1.029-2.039, p = 0.034) was an independent risk factor for failed medication abortion in women with non-viable pregnancies.
    UNASSIGNED: This is the first cohort study to identify risk factors for subsequent surgical intervention in women with viable or non-viable pregnancies who had undergone early medically induced abortions. The success rate of medical abortion is comparable in women with viable and non-viable pregnancies. Previous delivery is an independent risk factor for failed medical abortion. Clinical follow-up may be necessary for women who are at risk of subsequent surgical intervention.

    这项工作提出了使用多准则决策分析(MCDA)来选择更环保的分析程序。TOPSIS,代表与理想解决方案相似的偏好顺序技术,是可以用于基于各种标准对最佳备选方案进行排序或选择的MCDA方法的示例。本研究使用了13种分析程序作为TOPSIS输入选择,用于测定水样中米非司酮。输入数据,其中包括这些选择,使用基于12项绿色分析化学(GAC)原理的评估标准进行了描述。根据客观平均权重(MW),每个标准的权重分配相等.根据排序,最优选的分析方法是使用胶束电动色谱(SPE-MEKC)的固相萃取,固相萃取联合超高效液相色谱-串联质谱(SPE-UHPLC-MS/MS)技术排名最后。TOPSIS排名结果也与绿色指标NEMI进行了比较,生态规模,GAPI,同意,和AGREEPrep用于评估米非司酮测定的13种分析方法的绿色性。结果表明,只有AGREE度量工具与TOPSIS相关;然而,与其他度量工具没有相关性。分析结果表明,TOPSIS是根据绿色度对分析程序进行排名或选择的非常有用的工具,并且可以轻松地与其他绿色度量工具集成以进行方法绿色度评估。
    This work proposes the use of multi-criteria decision analysis (MCDA) to select a more environmentally friendly analytical procedure. TOPSIS, which stands for Technique for Order of Preference by Similarity to Ideal Solution, is an example of a MCDA method that may be used to rank or select best alternative based on various criteria. Thirteen analytical procedures were used in this study as TOPSIS input choices for mifepristone determination in water samples. The input data, which consisted of these choices, was described using assessment criteria based on 12 principles of green analytical chemistry (GAC). Based on the objective mean weighting (MW), the weights for each criterion were assigned equally. The most preferred analytical method according to the ranking was solid phase extraction with micellar electrokinetic chromatography (SPE-MEKC), while solid phase extraction combined with ultra-high performance liquid chromatography tandem mass spectrometry (SPE-UHPLC-MS/MS) was ranked last. TOPSIS ranking results were also compared to the green metrics NEMI, Eco-Scale, GAPI, AGREE, and AGREEprep that were used to assess the greenness of thirteen analytical methods for mifepristone determination. The results demonstrated that only the AGREE metric tool correlated with TOPSIS; however, there was no correlation with other metric tools. The analysis results suggest that TOPSIS is a very useful tool for ranking or selecting the analytical procedure in terms of its greenness and that it can be easily integrated with other green metrics tools for method greenness assessment.

    一种最罕见的异位妊娠,发病率为1:1800,是剖宫产瘢痕异位妊娠。这里,我们报道了1例28岁女性,该女性曾接受过两次剖宫产手术.她来到我们的分娩室,每次阴道斑点和腹痛,超声检查显示剖宫产疤痕异位妊娠。入院时最初的β-人绒毛膜促性腺激素(β-hCG)值为27,133mIU/mL。磁共振成像证实了她的超声检查结果。选择合并医疗管理,我们用氨甲蝶呤和米非司酮成功治疗了她,尽管β-hCG值较高,但仍避免手术干预。目前尚无确定的剖宫产瘢痕异位妊娠的标准化治疗方法,我们认为治疗必须针对每个患者的个人需求。我们的经验表明,米非司酮和全身性甲氨蝶呤联合治疗可能是一种疗效更好的有效方法。强调需要进一步研究。
    One of the rarest types of ectopic pregnancy, with an incidence of 1:1,800, is cesarean scar ectopic pregnancy. Here, we report the case of a 28-year-old woman who had undergone two previous cesarean sections. She arrived at our labor room with per vaginal spotting and abdominal pain with an ultrasound that revealed a cesarean scar ectopic pregnancy. The initial beta-human chorionic gonadotropin (β-hCG) value upon admission was 27,133 mIU/mL. Her ultrasound findings were confirmed with magnetic resonance imaging. Opting for combined medical management, we successfully treated her using systemic methotrexate and mifepristone, avoiding surgical intervention despite high β-hCG values. There is currently no established standardized treatment for cesarean scar ectopic pregnancies, and we feel that treatment must be tailored to every patient\'s individual needs. Our experience suggests that combining mifepristone and systemic methotrexate can be an effective approach with better curative effects, emphasizing the need for further research.
