    卵巢组织移植(OTT)的效率是根据卵巢功能恢复(95%的病例)确定的,活产数量(迄今为止全球超过200个)和青春期诱导。不幸的是,缺乏国际注册管理机构以及许多中心尚未报告其结果的事实,导致对确切生育率数据的了解不足。该研究的目的是描述我们使用OTT恢复卵巢功能和生育能力的经验。
    本研究设计为单中心,观察,回顾性,队列研究,包括2012年12月至2023年6月在我们中心接受OTT的女性。经肿瘤学家/血液学家批准后,在OTT前,我们解冻了一小段卵巢组织,并对其进行了分析,以检测是否存在微转移.解冻的卵巢组织在多个部位进行腹腔镜移植,包括剩余的卵巢和骨盆侧壁(原位移植)和/或腹壁(异位移植)。OTT之后,通过激素检测来监测卵巢功能,超声和彩色多普勒在大约4周的间隔。
    在2012年12月至2023年6月之间,有30名女性进行了OTT。在OTT之前,免疫组织化学和分子分析显示,所有解冻的卵巢组织样本均未发生微转移。在我们的30个女人系列中,20名女性患有卵巢早衰(POI),其余十例仍有月经少发和怀孕困难。在OTT之前和至少6个月随访的POI女性中,除了一名接受原位移植的妇女(14例中有13例)外,所有妇女的内分泌功能均恢复。在接受原位和异位移植的两名妇女中,有一名(2例病例中的1例)和所有接受异位移植的妇女(4例病例中的4例)。接受OTT以提高生育能力的女性月经周期和激素水平没有改变。总的来说,25名妇女怀孕10次,导致四个活产,两次持续怀孕和四次自然流产。
    我们的数据可以帮助患者和医生讨论和决定保留生育能力的必要性和可能性。
    UNASSIGNED: The efficiency of ovarian tissue transplantation (OTT) was established in terms of ovarian function recovery (95% of cases), number of live births (over 200 worldwide to date) and induction of puberty. Unfortunately, the lack of international registries and the fact that many centers have not yet reported their outcomes, lead to poor knowledge of the exact fertility data. The aim of the study is to describe our experience with OTT to restore ovarian function and fertility.
    UNASSIGNED: This study was designed as a single-center, observational, retrospective, cohort study that includes women who underwent OTT between December 2012 and June 2023 at our center. After approval by the oncologist/hematologist, a small fragment of ovarian tissue was thawed and analyzed to detect the presence of micrometastases before OTT. Thawed ovarian tissue was grafted laparoscopically at multiple sites, including the remaining ovary and pelvic side wall (orthotopic transplantation) and/or abdominal wall (heterotopic transplantation). After OTT, ovarian function was monitored by hormonal assay, ultrasound and color Doppler at approximately 4-week intervals.
    UNASSIGNED: Between December 2012 and June 2023, 30 women performed OTT. Prior to OTT, immunohistochemical and molecular analyses revealed no micrometastases in all thawed ovarian tissue samples. In our series of 30 women, 20 of women were on premature ovarian insufficiency (POI), and the remaining ten cases still had oligomenorrhea and difficulty getting pregnant. Among the women with POI before OTT and at least 6 months follow-up, recovery of endocrine function was observed in all but one woman who underwent orthotopic transplantation (13 of 14 cases), in one out of two women who underwent both orthotopic and heterotopic transplantation (1 of 2 cases) and in all women who underwent heterotopic transplantation (4 of 4 cases). Women who underwent OTT to enhance fertility had no alterations in menstrual cycle and hormonal levels. In total, ten pregnancies were obtained in 25 women, resulting in four live births, two ongoing pregnancies and four spontaneous abortions.
    UNASSIGNED: Our data can help patients and physicians in their discussions and decisions about the need and possibilities of preserving fertility.

    异位妊娠(EP)的发生率为1.3-2.4%。在血清妊娠试验阳性且无法通过经阴道超声检查(TVS)观察宫内孕囊(GS)后,开始怀疑EP。大约88%的输卵管EP是通过子宫内GS缺失和TVS期间附件肿块的存在而诊断的。使用甲氨蝶呤(MTX)进行EP的药物治疗具有成本效益,与手术治疗的成功率相似。胎儿心跳的存在,β-人绒毛膜促性腺激素>5000mIU/mL,和EP尺寸>4cm是使用MTX治疗EP的相对禁忌症。
    The incidence of ectopic pregnancy (EP) is 1.3-2.4%. Suspicion of EP starts after a positive serum pregnancy test and failure to visualize the intrauterine gestational sac (GS) by transvaginal sonography (TVS). About 88% of tubal EPs are diagnosed by absent intrauterine GS and the presence of an adnexal mass during TVS. Medical treatment of EP using methotrexate (MTX) is cost-effective with a similar success rate to surgical treatment. The presence of fetal heart beats, β-human chorionic gonadotropin >5000 mIU/mL, and EP size >4 cm are relative contraindications for using MTX in the treatment of EP.

    镰状细胞病,在撒哈拉以南非洲流行率很高的遗传病,是以常染色体隐性模式传播的.在怀孕期间进行筛查,可以鉴定S基因的携带者,这对未出生的孩子构成了风险。为了推广免疫层析试验的使用,我们为自己设定了建立流行病学概况和确定Emmel测试性能的任务。在刚果12个部门对孕妇进行的为期三个月的横断面分析研究,从闭经12周开始,接受产前咨询(ANC)。研究的变量是流行病学,血红蛋白的Emmel试验和免疫色谱分析。782名孕妇筛查,其中27.88%为镰状细胞性状,1.79%为纯合SS。镰状细胞患者的中位年龄为29岁,而不是25年(p=0.10)。教育水平高,婚姻状况,输血史和镰状细胞病,和高ANC数量在妊娠镰状细胞患者中更常见(p<0.05)。镰状细胞性状的频率范围为16.67至31.17%,纯合形式为0至66.67%,具体取决于部门。Emmel测试的敏感性和特异性分别为46%和99%,PPV和NPV分别为95%和81%。镰状细胞病运输,这两种形式都很高,年轻人更感兴趣,受过教育,农村地区已婚孕妇和医生以外的卫生人员的随访。
    Sickle-cell disease, a genetic condition with a high prevalence in sub-Saharan Africa, is transmitted in an autosomal recessive mode. Its screening during pregnancy makes it possible to identify carriers of the S gene which constitute a risk for the unborn child. In order to promote the use of immuno-chromatographic tests, we have set ourselves the task of establishing the epidemiological profile and determining the Emmel test performance. Analytical cross-sectional study of three months duration carried out in the 12 departments of Congo in pregnant women, from 12 weeks of amenorrhea, Admitted for Antenatal Consultation (ANC). The studied variables were epidemiological, Emmel test and immuno-chromatographic profile of haemoglobin. 782 pregnant women screened, of which 27.88% were AS sickle cell trait and 1.79% homozygous SS. The median age of sickle cell patients was 29 years vs. 25 years (p=0.10). High education level, married status, history of transfusion and sickle cell disease, and high ANC number were more common in pregnant sickle cell patients (p<0.05).The frequency of sickle cell trait ranged from 16.67 to 31.17% and homozygous forms from 0 to 66.67% depending on the department. The sensitivity and specificity of the Emmel test were 46% and 99% with PPV and NPV of 95% and 81% respectively. Sickle cell disease carriage, which is high in both forms, is more often of interest to young, educated, married pregnant women and follow-up by health personnel other than the doctor in rural areas.

    产后出血(PPH)是全球孕产妇死亡和发病的主要原因。多年来,关于种族和民族与PPH发生的相关性的研究并不多.这项研究的目的是评估种族和种族作为孕妇PPH发展的危险因素。遵循系统评价和荟萃分析(PRISMA)标准的首选报告项目,我们进行了分析,并使用GoogleScholar和PubMed进行了文献检索。在应用我们的纳入和排除标准后,搜索技术总共产生了8篇文章。分析包括7项观察性研究和1项随机对照试验。选择PPH的发生率作为主要结果指标。对八项研究的评估表明,尽管西班牙裔,亚洲人,夏威夷原住民,和其他太平洋岛民(NHOPI)有更高的机会发展PPH引起的子宫收缩,高加索人的输血率高于其他组。此外,与高加索人相比,非洲裔美国人或非洲后裔患失调性PPH的风险较低,但需要干预的失调性PPH的几率增加。另一方面,与非本地群体相比,美洲原住民增加了子宫收缩的几率。结果表明,与其他种族/民族相比,高加索人患PPH的风险最低。此外,研究表明,非裔美国人或非洲人后裔患PPH的几率较高,但患失张力PPH的风险较低.
    Postpartum hemorrhage (PPH) is a major cause of maternal death and morbidity worldwide. Throughout the years, there have not been many studies looking into the association of race and ethnicity with the occurrence of PPH. The goal of this study was to assess race and ethnicity as risk factors in the development of PPH in pregnant women. Following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) standards, we conducted the analysis and conducted a literature search using Google Scholar and PubMed. After applying our inclusion and exclusion criteria, the search technique yielded a total of eight articles. The analysis included seven observational studies and one randomized controlled trial. The incidence of PPH was chosen as the major outcome measure. An evaluation of eight studies revealed that although Hispanics, Asians, Native Hawaiians, and other Pacific Islanders (NHOPI) have a higher chance of developing PPH caused by uterine atony, Caucasians had a greater rate of transfusion than the other groups. In addition, compared to Caucasians, African Americans or African descendants had a lower risk of atonic PPH but increased odds of atonic PPH requiring interventions. On the other hand, compared to non-native groups, Native Americans had increased odds of uterine atony. The results showed that, in contrast to other races/ethnicities, Caucasians had the lowest risk of PPH. Additionally, it was shown that African Americans or those descended from Africans had a higher chance of PPH but a lower risk of atonic PPH.

    目的:近几十年来,美国青少年的怀孕和生育经历了急剧的下降。我们旨在估计2007-2017年14至18岁青少年中3种近端行为的变化对这些下降的贡献:1)第一次性交时年龄的延迟,2)性伴侣数量下降,3)避孕药具使用的变化,特别是摄取长效可逆避孕(LARC)。
    方法:我们调整了现有的迭代动态人口模型,并使用疾病控制和预防中心的青年风险行为调查的6波对其进行了参数化。我们将观察到的行为趋势与假设十年来行为不变的反事实情景进行了比较。我们按原因计算了结果,Year,和年龄。
    结果:我们发现这些行为的变化可以解释这十年来怀孕减少了496,200,78,500和40,700。分别,医疗和社会成本节省97.1亿美元,15.4亿美元,和7.96亿美元。LARC采用,特别是在18岁的年轻人中,可以解释避孕使用的大部分改善。这3个因素加在一起并不能完全解释观察到的出生率下降;每个伴侣的性行为下降了50%。
    结论:在这十年中,第一次性交的延迟对出生率下降的贡献最大,尽管所有考虑的行为都有重大影响。与早期模型的差异可能是由于所覆盖的年份和年龄差异造成的。基于证据的青少年怀孕预防计划,包括全面的性教育,对青少年友好的生殖健康服务,以及父母和社区的支持,可以继续解决这些司机,减少青少年怀孕。
    OBJECTIVE: Adolescent pregnancies and births in the United States have undergone dramatic declines in recent decades. We aimed to estimate the contribution of changes in 3 proximal behaviors to these declines among 14- to 18-year-olds for 2007-2017: 1) delays in age at first sexual intercourse, 2) declines in number of sexual partners, and 3) changes in contraceptive use, particularly uptake of long-acting reversible contraception (LARC).
    METHODS: We adapted an existing iterative dynamic population model and parameterized it using 6 waves of the Centers for Disease Control and Prevention\'s Youth Risk Behavior Survey. We compared pregnancies from observed behavioral trends with counterfactual scenarios that assumed constant behaviors over the decade. We calculated outcomes by cause, year, and age.
    RESULTS: We found that changes in these behaviors could explain pregnancy reductions of 496,200, 78,500, and 40,700 over the decade, respectively, with total medical and societal cost savings of $9.71 billion, $1.54 billion, and $796 million. LARC adoption, particularly among 18-year-olds, could explain much of the improvement from contraception use. The 3 factors together did not fully explain observed birth declines; adding a 50% decline in sex acts per partner did.
    CONCLUSIONS: Delays in first sexual intercourse contributed the most to declining births over this decade, although all behaviors considered had major effects. Differences from earlier models could result from differences in years and ages covered. Evidence-based teen pregnancy prevention programs, including comprehensive sex education, youth-friendly reproductive health services, and parental and community support, can continue to address these drivers and reduce teen pregnancy.

    未经证实:慢性炎症性疾病(CID),包括风湿性疾病和其他炎症,经常影响育龄妇女。肿瘤坏死因子抑制剂(TNFi)被广泛用于治疗CID,但关于TNFi暴露妊娠结局的信息有限.我们评估了1392例前瞻性报告的暴露于赛妥珠单抗(CZP)的妊娠结局,a聚乙二醇化,无Fc的TNFi,没有至最少的胎盘转移。
    UNASSIGNED:从CZP临床开发开始(2001年7月)到2020年11月1日,对UCB药物警戒全球安全数据库中CID患者的CZP暴露妊娠进行了回顾。为了限制偏见,分析的重点是前瞻性报告的已知妊娠结局的病例.
    未经批准:总共,报告了1392例孕妇CZP暴露和已知妊娠结局的前瞻性妊娠(n=1425);1021例至少有妊娠早期CZP暴露。在所有前瞻性结局的1259/1425(88.4%)中报告了活产。在20周(流产/人工流产)之前有150/1425(10.5%)妊娠损失,11/1425(0.8%)死产,和5/1392(0.4%)异位妊娠。30/1259(2.4%)活产婴儿中存在先天性畸形,根据亚特兰大大都会先天性缺陷计划标准,其中26人(2.1%)被认为是严重的。没有先天性畸形的模式。
    UNASSIGNED:在CZP暴露的妊娠中未观察到不良妊娠结局或先天性畸形的信号。尽管通过这种方法收集的数据的局限性(包括漏报,缺少信息,并且没有比较组)应该被考虑,这些数据为怀孕期间需要CZP治疗的CID女性提供了保证,和他们的主治医生。
    UNASSIGNED: Chronic inflammatory diseases (CIDs), including rheumatic diseases and other inflammatory conditions, often affect women of reproductive age. Tumor necrosis factor inhibitors (TNFi) are widely used to treat CID, but there is limited information on outcomes of TNFi-exposed pregnancies. We evaluated pregnancy outcomes from 1392 prospectively reported pregnancies exposed to certolizumab pegol (CZP), a PEGylated, Fc-free TNFi with no to minimal placental transfer.
    UNASSIGNED: CZP-exposed pregnancies in patients with CID from the UCB Pharmacovigilance global safety database were reviewed from the start of CZP clinical development (July 2001) to 1 November 2020. To limit bias, the analysis focused on prospectively reported cases with known pregnancy outcomes.
    UNASSIGNED: In total, 1392 prospective pregnancies with maternal CZP exposure and known pregnancy outcomes (n = 1425) were reported; 1021 had at least first-trimester CZP exposure. Live birth was reported in 1259/1425 (88.4%) of all prospective outcomes. There were 150/1425 (10.5%) pregnancy losses before 20 weeks (miscarriage/induced abortion), 11/1425 (0.8%) stillbirths, and 5/1392 (0.4%) ectopic pregnancies. Congenital malformations were present in 30/1259 (2.4%) live-born infants, of which 26 (2.1%) were considered major according to the Metropolitan Atlanta Congenital Defects Program criteria. There was no pattern of congenital malformations.
    UNASSIGNED: No signal for adverse pregnancy outcomes or congenital malformations was observed in CZP-exposed pregnancies. Although the limitations of data collected through this methodology (including underreporting, missing information, and absence of a comparator group) should be considered, these data provide reassurance for women with CID who require CZP treatment during pregnancy, and their treating physicians.

    OBJECTIVE: Pregnancies in women with polycythemia vera (PV) are associated with an increased risk of PV-related maternal complications and often result in miscarriage. Recommendations for the management of PV pregnancies are mainly based on studies with a small number of patients. A correlation between pregnancy outcome and postpartum course has been reported for essential thrombocythemia, but corresponding data for PV are lacking so far.
    METHODS: In 41 PV pregnancies, the pregnancy outcome, the use of PV-specific therapies (ie, acetylsalicylic acid, low-molecular weight heparin and/or interferon-alpha), and the postpartum PV course were investigated.
    RESULTS: A live birth rate of 51.2% (21/41 pregnancies) was observed. 43.9% of pregnancies ended in spontaneous abortion and 4.9% in stillbirth. A significantly increased live birth rate occurred in pregnancies with PV-specific therapies compared to standard antenatal care (69.0% vs. 8.3%; P < .0019). The use of PV-specific therapy significantly increased the number of maternal hemorrhages (P = .021) without increasing the risk of fetal complications. During the median postpartum follow-up period of 1.2 years (range 0.1-13.7), complicated postpartum PV occurred significantly more often after miscarriages (P = .035).
    CONCLUSIONS: According to our analysis, PV-specific therapy improved the live birth rate. Significantly more complicated postpartum PV courses were observed after miscarriages.

    BACKGROUND: We investigated association between sociodemographic characteristics and COVID-19 disease among pregnant women admitted to our unit, the largest high-risk maternity unit in the Milan metropolitan area.
    METHODS: Between March 1, 2020 and April 30, 2020, 896 pregnant women were admitted to our Institution and tested for COVID-19. We collected information regarding their sociodemographic characteristics. Additional information on geographical area of residence, number of family members, number of family members tested positive for COVID-19, and clinical data was collected for women tested positive for COVID-19. Odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of developing COVID-19 according to sociodemographic characteristics were estimated by unconditional logistic regression models.
    RESULTS: Among the 896 women enrolled, 50 resulted positive for COVID-19. Pregnant women aged ≥35 years had a significantly lower risk of developing the infection (crude OR = 0.29; 95% CI:0.16-0.55). Conversely, foreign women (crude OR = 3.32; 95% CI:1.89-5.81), unemployed women (crude OR = 3.09; 95% CI: 1.77-5.40), and women with an unemployed partner (crude OR = 3.16; 95% CI: 1.48-6.79) showed a significantly higher risk of infection. Ethnicity was positively associated with the risk of developing COVID-19 (mutually adjusted OR = 2.15; 95% CI:1.12-4.11) in the multivariate analysis. Foreign women with COVID-19 were more likely to have a lower education level (p < 0.01), to be unemployed (p < 0.01), and to live in larger families (p < 0.01) compared to Italian pregnant women.
    CONCLUSIONS: The socioeconomic conditions described are characteristic of immigration patterns in our metropolitan area. These factors may increase the risk of viral transmission, reducing the effectiveness of lockdown and social distancing.

    OBJECTIVE: To determine whether disease remission or low disease activity state at the beginning of pregnancy in SLE patients is associated with better pregnancy outcome.
    METHODS: Pregnancies in SLE patients prospectively monitored by pregnancy clinics at four rheumatology centres were enrolled. Patient demographics and clinical information were collected at baseline (pregnancy visit before 8 weeks of gestation) including whether patients were in remission according to the Definition of Remission in SLE (DORIS) criteria and and/or Lupus Low Disease Activity State (LLDAS). Univariate and multivariate analysis were performed to determine predictors of disease flare and adverse pregnancy outcomes (APOs) including preeclampsia, preterm delivery, small for gestational age infant, intrauterine growth restriction and intrauterine fetal death.
    RESULTS: A total of 347 pregnancies were observed in 281 SLE patients. Excluding early pregnancy losses, 212 pregnancies (69.7%) occurred in patients who were in remission at baseline, 33 (10.9%) in patients in LLDAS, and the remainder in active patients. Seventy-three flares (24%) were observed during pregnancy or puerperium, and 105 (34.5%) APOs occurred. Multivariate analysis revealed that patients in disease remission or taking HCQ were less likely to have disease flare, while a history of LN increased the risk. The risk of APOs was increased in patients with shorter disease duration, while being on HCQ resulted a protective variable. An almost significant association between complete remission and a decreased risk of APOs was observed.
    CONCLUSIONS: Prenatal planning with a firm treat-to-target goal of disease remission is an important strategy to reduce the risk of disease flares and severe obstetric complications in SLE pregnancies.

    Oocyte vitrification is considered experimental in the horse with only three live foals reported. The oxidative conditions induced by vitrification could in part explain the poor results and melatonin, a powerful antioxidant, could stimulate ROS metabolization and restore mitochondrial function in these oocytes. Our objective was to determine the oxidative status of vitrified equine oocytes and to analyze the effect of melatonin on mitochondrial-specific ROS (mROS), oocyte maturation, ICSI embryo development and viability. Immature, abattoir-derived oocytes were held for 15 h and vitrified in a final concentration of 20% EG, 20% DMSO and 0.65 M trehalose. In Experiment 1, overall ROS was determined by DCHF-DA; vitrification increased ROS production compared to non-vitrified controls (1.29 ± 0.22 vs 0.74 ± 0.25 a. u.; P = 0.0156). In Experiment 2, mROS was analyzed by MitoSOX™ in vitrified/warmed oocytes matured with (+) or without (-) supplementation of 10-9 M melatonin; mROS decreased in vitrified and non-vitrified oocytes matured in presence of melatonin (P < 0.05). In Experiment 3, we assessed the effect of melatonin supplementation on oocyte maturation, embryo development after ICSI, and viability by pregnancy establishment. Melatonin did not improve oocyte maturation, cleavage or blastocyst rate of non-vitrified oocytes. However, vitrified melatonin (+) oocytes reached similar cleavage (61, 75 and 77%, respectively) and blastocyst rate (15, 29 and 26%, respectively) than non-vitrified, melatonin (+) and (-) oocytes. Vitrified, melatonin (-) oocytes had lower cleavage (46%) and blastocyst rate (9%) compared to non-vitrified groups (P < 0.05), but no significant differences were observed when compared to vitrified melatonin (+). Although the lack of available recipients precluded the transfer of every blastocyst produced in our study, transferred embryos from non-vitrified oocytes resulted in 50 and 83% pregnancy rates while embryos from vitrified oocytes resulted in 17 and 33% pregnancy rates, from melatonin (+) and (-) treatments respectively. Two healthy foals, one colt from melatonin (+) and one filly from melatonin (-) treatment, were born from vitrified/warmed oocytes. Gestation lengths (considering day 0 = day of ICSI) were 338 days for the colt and 329 days for the filly, respectively. Our work showed for the first time that in the horse, as in other species, intracellular reactive oxygen species are increased by the process of vitrification. Melatonin was useful in reducing mitochondrial-related ROS and improving ICSI embryo development, although the lower pregnancy rate in presence of melatonin should be further analyzed in future studies. To our knowledge this is the first report of melatonin supplementation to an in vitro embryo culture system and its use to improve embryo developmental competence of vitrified oocytes following ICSI.
