    目的:评估血栓弹力图的预测价值,血常规指标,超声测量,胎盘厚度对胎儿结局的影响。
    方法:对我院2020年4月至2022年6月218名孕妇进行回顾性分析。将母亲分为有利(n=164)和不利(n=54)胎儿结局组。我们比较了血栓弹力图,血细胞计数,和超声参数,包括胎盘厚度,两组之间。针对个体评估类型及其组合,开发了使用套索回归的预测模型。通过ROC曲线和Delong检验评估模型的有效性。
    结果:血栓弹力图显示R值明显更高(P=0.004),角度(P<0.001),和MA(P=0.002),而与有利结果组相比,不良结果组的K明显降低(P<0.001)。外周血分析显示白细胞水平升高(P<0.001),CRP(P=0.001),不良结局组PLR(P<0.001)。超声评估显示S/D显着增加(P<0.001),PI(P=0.016),RI(P<0.001),不良结局组的胎盘厚度(P<0.001)。血栓弹力图的曲线下面积(AUC)(4个特征),外周血指数(3个特征),超声参数(4个特征),和组合指数模型(11个特征)分别为0.774、0.779、0.961和0.978。Delong检验表明,联合模型的AUC与超声参数无显著差异(P>0.05),但优于基于血栓弹力图的模型。外周血指数,仅胎盘厚度(P<0.001)。
    结论:本研究强调了超声指标在确定不良妊娠结局风险方面的无与伦比的预测价值。强调它们在产前风险评估和监测框架中的关键作用。
    OBJECTIVE: To evaluate the predictive value of thromboelastography, routine blood indices, ultrasound measurements, and placental thickness for fetal outcome.
    METHODS: A retrospective analysis of 218 expectant mothers at our hospital from April 2020 to June 2022 was conducted. Mothers were classified into favorable (n=164) and adverse (n=54) fetal outcome groups. We compared thromboelastography, blood counts, and ultrasound parameters, including placental thickness, between the two groups. Predictive models using lasso regression were developed for individual assessment type and their combinations. Model efficacies were evaluated by ROC curves and Delong\'s test.
    RESULTS: Thromboelastography indicated significantly higher values of R (P=0.004), Angle (P<0.001), and MA (P=0.002) while notably lower K (P<0.001) in the adverse outcome group compared to the favorable outcome group. Peripheral blood analysis showed elevated levels of WBC (P<0.001), CRP (P=0.001), and PLR (P<0.001) in the adverse outcome group. Ultrasound assessments revealed significant increases in S/D (P<0.001), PI (P=0.016), RI (P<0.001), and placental thickness (P<0.001) in the adverse outcome group. The areas under the curve (AUCs) for the thromboelastography (4 features), peripheral blood indices (3 features), ultrasound parameters (4 features), and combined index model (11 features) were 0.774, 0.779, 0.961, and 0.978, respectively. Delong\'s test indicated that the combined model\'s AUC did not significantly differ from that of the ultrasound parameters (P>0.05) but was superior to the models based on thromboelastography, peripheral blood indices, and placental thickness alone (P<0.001).
    CONCLUSIONS: This study underscores the unparalleled predictive value of ultrasound metrics in identifying the risk of adverse pregnancy outcomes, highlighting their critical role in prenatal risk assessment and monitoring frameworks.

    随着女性生育年龄的推迟和年轻人癌症发病率的提高,生育保存在育龄期变得越来越重要。怀孕期间的化疗对于母体癌症治疗和胎儿结局至关重要。需要进一步研究化疗药物联合用药引起的卵巢损伤及对子代发育的长期影响,并详细了解化疗药物的副作用。在这项研究中,化疗药物组合对卵巢功能有显著影响,尤其是表柔比星/环磷酰胺(EC)组合导致左右卵巢发育失衡。暴露于EC和顺铂/紫杉醇(TP)增加了祖细胞的数量,而减少了窦卵泡和黄体的数量。至于发情周期,EC暴露导致发情期和发情期更长,而TP暴露仅延长了动情期。EC和TP通过降低SF1和P450arom的表达影响类固醇的生物合成。在EC和TP暴露组中都检测到γ-H2AX。关于注射EC对4T1荷瘤小鼠后代的影响,与对照组相比,在身体和神经发育方面没有观察到显著差异,但是卵巢的重量,后代的发情周期明显不同。化疗药物组合表现出卵巢毒性,不仅会对卵泡细胞造成直接损伤,还会破坏类固醇的生物合成。观察到母体荷瘤小鼠暴露于化疗药物的后代生殖系统紊乱,但具体机制仍需进一步探索。
    With the postponement of female reproductive age and the higher incidence of cancer in young people, fertility preservation has become increasingly important in childbearing age. Chemotherapy during pregnancy is crucial for maternal cancer treatments and fetal outcomes. It is a need to further study ovarian damage caused by chemotherapy drug combinations and long-term effects on offspring development, and a detailed understanding of side effects of chemotherapy drugs. In this study, chemotherapy drug combinations significantly impacted on ovarian function, especially epirubicin/cyclophosphamide (EC) combination led to an unbalance in the development of the left and right ovary. Exposure to EC and cisplatin/paclitaxel (TP) increased the number of progenitor follicles while decreased the count of antral follicles and corpora luteum. As to the estrus cycle, EC exposure resulted in a longer estrus period and diestrus period, while TP exposure only extended the diestrus period. EC and TP affected steroid biosynthesis by reducing the expression of SF1 and P450arom.γ-H2AX was detected in both EC and TP exposure groups. As to the impact on the offspring from 4T1 tumor-bearing pregnant mice injected with EC, no significant difference was observed in the physical and neurological development compared to the control, but the ovarian weights, estrus cycles of the offspring were significantly different. Chemotherapy drug combinations exhibit ovarian toxicity, not only causing direct damage on the follicle cells but also disrupting steroid biosynthesis. The reproductive system of offspring from maternal tumor-bearing mice exposed to chemotherapy drugs was observed disorder, but the concrete mechanism still needs further exploration.

    少女怀孕的全球性问题影响着年轻母亲的健康以及即将出生的婴儿的健康。既是医疗问题,也是公共卫生问题,青少年母亲及其子女被视为高危人群。目前的研究工作是以社区为基础的比较研究,以了解少女怀孕对健康的影响,营养,和第一个出生的孩子的发展里程碑。
    三个参数,即,胎儿结局,婴儿的出生体重,和孩子的发展里程碑,被选中分析少女怀孕对第一胎的影响。博帕尔农村地区的母亲接受了采访,然后根据他们的年龄将其分为两组-青少年和非青少年母亲。
    与非少女母亲的孩子相比,少女母亲的孩子出生体重>2.5公斤的机会减少16%。观察到胎儿结局(少女母亲与非少女母亲)的显着统计学差异,P值为0.0008。少女母亲的活产率为80.77%(63),非少女母亲为97.44%(76),而<1.5kg的低出生体重(LBW)在青少年组中增加了5.35倍。
    发现非少女母亲的第一个出生的孩子比少女母亲的孩子更健康;少女怀孕对健康有不利影响,营养,以及第一个出生的孩子的发育,并可能导致诸如死胎之类的问题,LBW,和早产。
    UNASSIGNED: The global problem of teenage pregnancy affects health of the young mother as well as health of the baby to be born. Being both a medical and public health problem, teenage mothers as well as their children are considered as high-risk groups. Current research work is a community-based comparative study to understand the consequences of teenage pregnancy on the health, nutrition, and developmental milestones of the first-born children.
    UNASSIGNED: Three parameters, namely, fetal outcome, birth weight of the baby, and child\'s milestones of development, were chosen to analyze the effects of teenage pregnancy on the first-born child. Mothers in a rural district at Bhopal were interviewed and then classified into two groups based on their age - teenage and non-teenage mothers.
    UNASSIGNED: The child of teenage mothers had 16% less chances of having birth weight >2.5 kg in comparison to the child of non-teenage mothers. A significant statistical difference in the fetal outcome (teenage mothers vs non-teenage mothers) was observed with a P value of 0.0008. Live births were 80.77% (63) in teenage mothers against 97.44% (76) in non-teenage mothers, whereas a low birth weight (LBW) of <1.5 kg was 5.35 times more in the teenage group.
    UNASSIGNED: First-born children of non-teenage mothers were found to be healthier compared to those of the teenage mothers; teenage pregnancy has adverse effects on the health, nutrition, and development of the first-born children and may lead to problems such as still births, LBW, and pre-mature child birth.

    背景:家庭支持是妊娠结局的生活习惯和相关健康行为的决定因素之一。在印度,仍然实行联合家庭制度。由于教育,城市化,和工业化,家庭机构继续在人们的生活中发挥核心作用。怀孕是女性一生中的关键时期。怀孕期间的良好护理对于母亲和新生婴儿的健康很重要。在此期间,荷尔蒙的变化是复杂的,涉及多种激素一起工作,以支持发育中的胎儿和准备母亲的身体分娩,delivery,和母乳喂养。为了避免母婴并发症,在整个怀孕和产后期间,她需要家人的支持。
    目的:本研究旨在评估孕期家庭支持水平和质量对母婴结局的影响,并确定孕早期社会人口统计学变量与家庭支持水平和质量影响之间的关联。
    方法:本研究采用定量方法和调查研究设计。数据来自卡拉德的四个初级保健中心,马哈拉施特拉邦,印度,即,Rethare,Vadgaon,羽衣甘蓝,和Supane。采用连续抽样技术从Rethare中选择344名受试者,Vadgaon,羽衣甘蓝,和卡拉德·塔卢卡的苏帕恩地区。数据是在怀孕前三个月完成之前收集的,然后在妊娠中期和分娩后。经评估,该工具由代表一系列专业的专家验证,包括社区健康护理,心理健康护理,产科妇科,和儿科护理。对30个样品进行了初步研究。对收集的数据进行描述性和推断性统计分析。
    结果:研究结果显示,孕早期获得的心理社会支持与分娩时完成的总孕周之间存在显著关联(p<0.05)。该研究表明,在妊娠早期需要社会心理支持,以获得更好的母婴结局。
    结论:孕妇在妊娠早期需要社会心理家庭支持,以实现母婴结局。
    BACKGROUND: Family support is one of the determinants of lifestyle habits and relevant health behavior for pregnancy outcomes. In India, the joint family system is still practiced. Due to education, urbanization, and industrialization, the family institution continues to play a central role in people\'s lives. Pregnancy is a crucial period in women\'s lives. Good care during pregnancy is important for the health of the mother and the newborn baby. During this period, hormonal changes are complex and involve multiple hormones working together to support the developing fetus and prepare the mother\'s body for labor, delivery, and breastfeeding. To avoid maternal and fetal complications, she needs support from her family throughout pregnancy and the postnatal period.
    OBJECTIVE: This study aims to evaluate the influence of the level and quality of family support during pregnancy on maternal and fetal outcomes and to identify any association between the sociodemographic variables and the impact of the level and quality of family support during the first trimester.
    METHODS: This study used a quantitative approach with a survey research design. Data were collected from four Primary Health Centers at Karad, Maharashtra, India, i.e., Rethare, Vadgaon, Kale, and Supane. A consecutive sampling technique was used to select the 344 subjects from the Rethare, Vadgaon, Kale, and Supane areas of Karad Taluka. Data were collected before the completion of the first three months of pregnancy, then during the second trimester and after delivery. Upon evaluation, the tool was validated by experts representing a range of specialties, including community health nursing, mental health nursing, obstetric gynecology, and pediatric care. A pilot study was conducted on 30 samples. The data collected were analyzed by using descriptive and inferential statistics.
    RESULTS: The findings of the study show a significant association between the psychosocial support received in the first trimester and the total gestational weeks completed at the time of delivery (p < 0.05). The study suggests the need for psychosocial support during the first trimester for better maternal and fetal outcomes.
    CONCLUSIONS: Psychosocial family support is needed by pregnant women during the first trimester to achieve maternal and fetal outcomes.

    简介:少女怀孕是全球公共卫生挑战,它是撒哈拉以南非洲和乌干达报告的高孕产妇和新生儿发病率和死亡率的主要原因。然而,乌干达青少年中关于妊娠结局及其相关因素的数据很少.这项研究的目的是确定在坎帕拉国家转诊医院分娩的青少年的患病率和与妊娠结局相关的因素。乌干达。材料和方法:这项横断面研究是在坎帕拉国家转诊医院分娩的少女母亲中进行的,乌干达。对于那些符合资格标准的人,连续招募参与者。感兴趣的结局包括不良的产妇结局,难产被用作替代,不良的胎儿结局,出生窒息被用作替代。Logistic回归分析用于确定自变量和因变量之间的关联,具有5%的统计学意义(α=0.05)。结果:少女妊娠与不良产妇结局相关,包括难产(18%)和早产(5.5%)。在研究期间没有产妇死亡。在本研究人群中观察到的不良胎儿结局包括低出生体重(83%),出生窒息(18%),和死产(4%)。与不良产妇结局相关的唯一因素是胎龄,其中少女母亲在37周前分娩的可能性是其4倍。相关地,十几岁的母亲有81%的机会早产。结论:除早产外,少女妊娠通常与不良母婴结局无关。不良妊娠结局的原因可能是妇科和生物不成熟的结合,以及不利的社会经济压力。
    Introduction: Teenage pregnancy is a global public health challenge, and it is a major contributor to the high maternal and neonatal morbidity and mortality rates reported in sub-Saharan Africa and Uganda. However, there is a paucity of data regarding pregnancy outcomes and their associated factors among teenagers in Uganda. The purpose of this study was to determine the prevalence and factors associated with pregnancy outcomes among teenagers who delivered at a National Referral Hospital in Kampala, Uganda. Materials and Methods: This cross-sectional study was conducted among teenage mothers who delivered at a National Referral Hospital in Kampala, Uganda. Consecutive participant recruitment was done for those who fulfilled the eligibility criteria. The outcomes of interest included adverse maternal outcome with obstructed labor being used as a proxy and adverse fetal outcomes with birth asphyxia used as a proxy. Logistic regression analysis was used to determine the association between independent and dependent variables with a 5% level of statistical significance (α = 0.05). Results: Teenage pregnancy was associated with adverse maternal outcomes which included obstructed labor (18%) and preterm labor (5.5%). There were no maternal deaths during the study period. Adverse fetal outcomes observed in this study population included low birth weight (83%), birth asphyxia (18%), and stillbirth (4%). The only factor associated with adverse maternal outcome was gestational age where teenage mothers had 4 times likelihood of delivering before 37 weeks. Relatedly, teenage mothers had an 81% chance of having a preterm birth. Conclusion: Teenage pregnancy was generally not associated with adverse maternal or fetal outcomes except for preterm birth. The reasons for adverse pregnancy outcomes may reflect a combination of gynecological and biological immaturity, as well as adverse socioeconomic pressures.

    目的:关于足月臀位最安全的分娩方式的争论仍未解决。阴道臀位分娩(VBB)与选择性剖腹产(CS)在胎儿结局方面的比较有利于CS。然而,本研究探讨了尝试VBB是否与不良胎儿结局相关的问题.此外,该研究评估了导致VBB成功的因素,并说明了VBB管理中可能存在的错误。
    方法:我们对围产期中心I级足月臀位出生的胎儿,母性,通过比较成功与不成功的VBB尝试以及所有尝试的VBB与产科结果CS包括成功VBB的预测因子的多变量分析。进行了严重不良事件(SAE)的根本原因分析,以评估导致VBB胎儿结局较差的因素。
    结果:在863例臀位病例中,在78%中进行了CS,在22%中尝试了VBB,57%的人成功了。比较成功与不成功的VBB尝试,成功的VBB显示显着降低母体失血量(p<0.001),但脐动脉pH值(UApH)较差(p<0.001),而其他胎儿结局参数无显著差异。成功尝试VBB的预测因素是体重指数(BMI)低于30.0kg/m2(p=0.010)和多奇偶校验(p=0.003)。将所有尝试的VBB与CS进行比较,母亲失血率明显高于CS(p<0.001),虽然VBB尝试的胎儿结局明显更差,包括较差的Apgar评分(p<0.001),UApH值较差(p<0.001),新生儿重症监护病房(NICU)的转移率较高(p<0.001),并且在最初24小时内呼吸支持的发生率较高(p=0.003)。
    结论:VBB失败的尝试表明UApH明显恶化,没有降低Apgar评分或更高的NICU转移率。肥胖患者成功VBB的可能性降低9%,多胎妇女的可能性提高2.5倍。尝试VBB应该包括详细的劳动前咨询,关于预测成功因素,一个经验丰富的团队,和出生时的一致管理。
    OBJECTIVE: The debate about the safest birth mode for breech presentation at term remains unresolved. The comparison of a vaginal breech birth (VBB) with an elective caesarean section (CS) regarding fetal outcomes favors the CS. However, the question of whether attempting a VBB is associated with poorer fetal outcomes is examined in this study. Additionally, the study evaluates factors contributing to a successful VBB and illustrates possible errors in VBB management.
    METHODS: We performed a retrospective analysis of term breech births over 15 years in a Perinatal Center Level I regarding fetal, maternal, and obstetric outcomes by comparing successful with unsuccessful VBB attempt and all attempted VBB vs. CS including a multivariate analysis of predictors for a successful VBB. A root cause analysis of severe adverse events (SAE) was conducted to evaluate factors leading to poorer fetal outcomes in VBB.
    RESULTS: Of 863 breech cases, in 78 % a CS was performed and in 22 % a VBB was attempted, with 57 % succeeding. Comparing successful with unsuccessful VBB attempts, successful VBB showed significantly lower maternal blood loss (p < 0.001) but poorer umbilical arterial pH (UApH) (p < 0.001), while other fetal outcome parameters showed no significant differences. Predictive factors for a successful VBB attempt were a body mass index (BMI) below 30.0 kg/m2 (p = 0.010) and multiparity (p = 0.003). Comparing all attempted VBB to CS, maternal blood loss was significantly higher in CS (p < 0.001), while fetal outcomes were significantly worse in VBB attempts, included poorer Apgar scores (p < 0.001), poorer UApH values (p < 0.001), higher transfer rate to the Neonatal Intensive Care Unit (NICU) (p < 0.001) and higher rate of respiratory support in the first 24 h (p = 0.003).
    CONCLUSIONS: The failed attempt of VBB indicates significantly worse UApH without lower Apgar scores or higher transfer rate to the NICU. The likelihood of a successful VBB is 9% lower with obesity and 2.5 times higher in multiparous women. Attempting a VBB should include detailed pre-labor counseling, regarding predictive success factors, an experienced team, and consistent management during birth.

    引言家庭暴力(DV)在女性中非常普遍,尤其是孕妇,这是一个严重的公共卫生问题,可能导致妊娠并发症,威胁孕产妇和胎儿的结局。研究已经确定,怀孕期间的家庭言语虐待(DVA)在25岁以下的女性以及受教育程度低的女性中更为常见。这项研究确定了孕妇言语虐待的总体患病率,在半城市人口中,其独特之处在于,还确定了先前有女童的孕妇的言语虐待。这项研究有助于医疗保健提供者确定怀孕期间DVA的潜在原因,并以咨询的形式为孕妇和家庭提供及时的干预措施。目的这项观察性研究旨在评估孕妇中DVA的患病率。为了确定孕妇中DVA发生的三个月,并探索DVA与年龄的关系,就业状况,胎次胎龄,出生体重。材料和方法这是一项为期六个月的基于医院的观察性研究,在Pimpri的Patil医学院妇产科住院部(IPD)进行,浦那。从200名接受分娩的孕妇中获得了同意,并提供了经过验证的DV评估筛查问卷的修改副本。使用GraphPadPrism10进行统计分析。任何需要的地方都采用卡方检验,并且小于0.05的p值被认为是显著的。结果该研究包括200名孕妇,他们被送进医院分娩。以言语虐待形式出现的DV的患病率为200人中的74人(37%)。该妇女的工作状况对DVA有影响。在18至23岁的年龄组中,言语虐待也显着增加(68%)。先前分娩的女性儿童也对DVA产生了重大影响,结果变得更加普遍,特别是如果两个女孩之前出生(80%)。该研究还指出,DVA孕妇的早产率更高,为57%。结论研究表明,女性,即使在现代,在怀孕期间体验DVA,尤其是在年轻群体中。还发现,由于孕产妇失业而在经济上依赖的妇女中,这种情况更为普遍。因此,有必要对孕妇进行常规DVA筛查,以避免潜在的有害妊娠结局,并防止持续的滥用.
    Introduction Domestic violence (DV) in the form of verbal abuse is very common among women, especially pregnant women, posing as a serious public health issue that could lead to complications in pregnancy and threaten maternal and fetal outcomes. Studies have determined that domestic verbal abuse (DVA) in pregnancy was more common in women less than 25 years of age as well as in those with low education levels. This study determined the overall prevalence of verbal abuse in pregnant women, in a semi-urban population and is unique in that the verbal abuse in pregnant women with a previous girl child was also determined. This study helps healthcare providers identify the potential causes of DVA in pregnancy and provide timely interventions in the form of counseling for pregnant women and families. Objective This observational study was carried out to assess the prevalence of DVA among pregnant women, to determine the trimester of occurrence of DVA among pregnant women, and to explore the associations of DVA with age, employment status, parity gestational age, and birth weight.  Materials and methods This was a six-month hospital-based observational study conducted at Dr D. Y. Patil Medical College\'s in-patient department (IPD) of Obstetrics and Gynecology in Pimpri, Pune. Consent was obtained from 200 pregnant women who received admission for delivery and provided a validated modified copy of a DV assessment screening questionnaire. A statistical analysis was performed using GraphPad Prism 10. A Chi-square test was employed wherever required, and a p-value of less than 0.05 was considered significant. Results The study included 200 pregnant women, who were admitted to the hospital for delivery. The prevalence of DV in the form of verbal abuse was noted to be 74 out of 200 (37%). The working status of the woman showed an influence on DVA. There was also a significant increase in verbal abuse (68%) among the age group between 18 and 23 years. The previous delivery of a female child also had a significant impact on DVA, which turned out to be more prevalent, particularly if two female children were born previously (80%). The study also noted higher rates of preterm deliveries in pregnant women with DVA being 57%. Conclusion The study demonstrates that women, even in modern times, experience DVA during pregnancy, especially among the younger age group. It has also been found that it is more common among women who are financially dependent due to maternal unemployment. As a result, there is a need to routinely screen pregnant women for DVA to avoid potentially detrimental pregnancy outcomes and to prevent ongoing abuse.

    背景:妊娠早期空腹血糖(FPG)升高的意义尚不确定。
    目的:荟萃分析的主要结果是分析妊娠早期FPG升高是否可以预测24-28周时GDM的发展。次要结果是确定常用的FPG截止值5.1mmol/L(92mg/dL),5.6mmol/L(100mg/dL),6.1mmol/L(110mg/dL)与不良妊娠事件相关。
    方法:在数据库中搜索了从2010年开始发表的文章,以研究孕早期FPG与胎儿不良结局之间的关系。
    方法:共有16项研究,涉及115,899例妊娠,符合纳入标准。
    方法:患GDM的妇女早孕FPG明显高于未患GDM的妇女[MD0.29mmoL/l(5mg/dL);95%CI:0.21-0.38;P<0.00001]。孕早期FPG≥5.1mmol/L(92mg/dL)预测24-28周时GDM的发展[RR3.93(95%CI:2.67-5.77);P<0.0000],先兆子痫[RR1.55(95CI:1.14-2.12);P=0.006],妊娠期高血压[RR1.47(95CI:1.20-1.79);P=0.0001],胎龄大(LGA)[RR1.32(95CI:1.13-1.54);P=0.0004],巨大儿[RR1.29(95CI:1.15-1.44);P<0.001]。然而,在上述门槛下,早产率,下段剖宫产术(LSCS),小于胎龄(SGA),和新生儿低血糖没有明显升高。孕早期FPG≥5.6mmol/L(100mg/dL)与巨大儿的发生相关[RR1.47(95%CI:1.22-1.79);P<0.0001],LGA[RR1.43(95CI:1.24-1.65);P<0.00001],和早产[RR1.51(95CI:1.15-1.98);P=0.003],但不是SGA和LSCS.
    结论:只有一项研究报告孕早期FPG为6.1mmol/L(110mg/dL),因此没有被分析。
    结论:24-28周时发生GDM的风险随妊娠早期FPG升高而线性增加。妊娠早期FPG截止值分别为5.1mmol/L(92mg/dL)和5.6mmol/L(100mg/dL),可预测几种不良妊娠结局。
    BACKGROUND: The implication of intermediately elevated fasting plasma glucose (FPG) in the first trimester of pregnancy is uncertain.
    OBJECTIVE: The primary outcome of the meta-analysis was to analyze if intermediately elevated first-trimester FPG could predict development of GDM at 24-28 weeks. The secondary outcomes were to determine if the commonly used FPG cut-offs 5.1 mmol/L (92 mg/dL), 5.6 mmol/L (100 mg/dL), and 6.1 mmol/L (110 mg/dL) correlated with adverse pregnancy events.
    METHODS: Databases were searched for articles published from 2010 onwards for studies examining the relationship between first-trimester FPG and adverse fetomaternal outcomes.
    METHODS: A total of sixteen studies involving 115,899 pregnancies satisfied the inclusion criteria.
    METHODS: Women who developed GDM had a significantly higher first-trimester FPG than those who did not [MD 0.29 mmoL/l (5 mg/dL); 95 % CI: 0.21-0.38; P < 0.00001]. First-trimester FPG ≥5.1 mmol/L (92 mg/dL) predicted the development of GDM at 24-28 weeks [RR 3.93 (95 % CI: 2.67-5.77); P < 0.0000], pre-eclampsia [RR 1.55 (95%CI:1.14-2.12); P = 0.006], gestational hypertension [RR1.47 (95%CI:1.20-1.79); P = 0.0001], large-for-gestational-age (LGA) [RR 1.32 (95%CI:1.13-1.54); P = 0.0004], and macrosomia [RR1.29 (95%CI:1.15-1.44); P < 0.001]. However, at the above threshold, the rates of preterm delivery, lower-segment cesarean section (LSCS), small-for gestational age (SGA), and neonatal hypoglycemia were not significantly higher. First-trimester FPG ≥5.6 mmol/L (100 mg/dL) correlated with occurrence of macrosomia [RR1.47 (95 % CI:1.22-1.79); P < 0.0001], LGA [RR 1.43 (95%CI:1.24-1.65); P < 0.00001], and preterm delivery [RR1.51 (95%CI:1.15-1.98); P = 0.003], but not SGA and LSCS.
    CONCLUSIONS: Only one study reported outcomes at first-trimester FPG of 6.1 mmol/L (110 mg/dL), and hence was not analyzed.
    CONCLUSIONS: The risk of development of GDM at 24-28 weeks increased linearly with higher first-trimester FPG. First trimester FPG cut-offs of 5.1 mmol/L (92 mg/dL) and 5.6 mmol/L (100 mg/dL) predicted several adverse pregnancy outcomes.

    方法:26岁,初产妇在妊娠17周时接受了羊膜穿刺术,因为在妊娠16周时21三体的非侵入性产前检测(NIPT)阳性。羊膜穿刺术显示核型为47,XX,+21[3]/46,XX[17],未培养羊膜细胞上的多重连接依赖性探针扩增(MLPA)显示rsaX(P095)×2,(13,18,21)×2。她在妊娠21周时接受了脐带穿刺术(脐带血采样),结果显示核型为47,XX,+21[2]/46,XX[48]。妊娠27周时,她被转诊到我们医院接受遗传咨询,重复羊膜穿刺术显示20/20个菌落的核型为46,XX。对从未培养的羊膜细胞和亲本血液中提取的DNA进行定量荧光聚合酶链反应(QF-PCR)分析,排除了单亲二体(UPD)21。对从未培养的羊膜细胞提取的DNA进行的阵列比较基因组杂交(aCGH)分析显示arr(1-22,X)×2,Y×0,没有基因组失衡。对104个未培养的羊膜细胞进行间期荧光原位杂交(FISH)分析,检测到一个细胞(1/104=0.9%)具有三体性21,而其余细胞为二体性21,而正常对照组为0%(0/100)。该妇女被鼓励继续怀孕。妊娠持续到妊娠38周,一名2771g女婴分娩时无表型异常。脐带血的CGH分析显示ARR(1-22,X)×2,Y×0没有基因组失衡。脐带的核型为47,XX,+21[3]/46,XX[37]。胎盘的核型为46,XX。在3½个月的年龄进行随访时,新生儿表型正常,发育正常。外周血中40/40细胞的核型为46,XX。口腔粘膜细胞的间期FISH分析检测到100/100细胞中的正常二体21细胞。
    结论:孕中期羊膜穿刺术和宫腔穿刺术中低水平镶嵌21三体与围产期21三体细胞系逐渐减少和良好的胎儿结局有关。
    OBJECTIVE: We present low-level mosaic trisomy 21 at amniocentesis and cordocentesis in a pregnancy associated with a favorable fetal outcome.
    METHODS: A 26-year-old, primigravid woman underwent amniocentesis at 17 weeks of gestation because of positive non-invasive prenatal testing (NIPT) for trisomy 21 at 16 weeks of gestation. Amniocentesis revealed a karyotype of 47,XX,+21[3]/46,XX[17], and multiplex ligation-dependent probe amplification (MLPA) on uncultured amniocytes revealed rsa X(P095) × 2, (13, 18, 21) × 2. She underwent cordocentesis (cord blood sampling) at 21 weeks of gestation which revealed a karyotype of 47,XX,+21[2]/46,XX[48]. At 27 weeks of gestation, she was referred to our hospital for genetic counseling, and repeat amniocentesis revealed a karyotype of 46,XX in 20/20 colonies. Quantitative fluorescent polymerase chain reaction (QF-PCR) analysis on the DNA extracted from uncultured amniocytes and parental bloods excluded uniparental disomy (UPD) 21. Array comparative genomic hybridization (aCGH) analysis on the DNA extracted from uncultured amniocytes revealed arr (1-22,X) × 2, Y × 0 with no genomic imbalance. Interphase fluorescence in situ hybridization (FISH) analysis on 104 uncultured amniocytes detected one cell (1/104 = 0.9%) with trisomy 21, while the rest cells were disomy 21, compared with 0% (0/100) in the normal control. The woman was encouraged to continue the pregnancy. The pregnancy was carried to 38 weeks of gestation, and a 2771-g female baby was delivered no phenotypic abnormality. aCGH analysis on the cord blood showed arr (1-22,X) × 2, Y × 0 with no genomic imbalance. The umbilical cord had a karyotype of 47,XX,+21[3]/46,XX[37]. The placenta had a karyotype of 46,XX. When follow-up at age 3½ months, the neonate was phenotypically normal and had normal development. The peripheral blood had a karyotype of 46,XX in 40/40 cells. Interphase FISH analysis on buccal mucosal cells detected normal disomy 21 cells in 100/100 cells.
    CONCLUSIONS: Low-level mosaic trisomy 21 at amniocentesis and cordocentesis in the second trimester can be associated with perinatal progressive decrease of the trisomy 21 cell line and a favorable fetal outcome.

    目的:子痫前期(PE)是孕产妇和胎儿死亡的主要原因,和早产。先前的研究表明,脂质分离术可能会延长妊娠,即肝素介导的体外LDL沉淀(HELP)-和硫酸葡聚糖纤维素(DSC)-单采术。我们现在报道双膜血浆置换(DFPP)在早发型先兆子痫(eoPE)中的应用。
    方法:通过脂蛋白单采术(DRKS00004527)评估PE妊娠延长的开放试验研究。两名患有eoPE的妇女通过DFPP治疗,并与通过HELP-单采术治疗的6名患有eoPE的患者的历史队列进行比较(NCT01967355)。
    方法:母亲和婴儿的临床结局和妊娠延长(入院至出生时间)。
    结果:患者1(33岁;22+5/7GW)接受4个DFPP。分娩第19天;出生体重270g;第132天出院时体重2134g。患者2(35y;21+4/7GW)接受2DFPP。第19天交货;出生体重465g;第104天卸货体重2540g。两名患者对DFPP的耐受性良好。
    结论:DFPP被证明是挽救的,怀孕保持稳定长达19天。尽管婴儿出生时非常早产,但最终两个婴儿都可以出院。在DFPP和HELP-单采之间没有观察到相关的临床差异。因此,DFPP可以扩展可用的单采技术的范围,以延长早发型先兆子痫的妊娠时间。然而,需要进一步的研究来获得更多的信息。注册机构:(DRKS00004527)。
    OBJECTIVE: Preeclampsia (PE) is a major cause of maternal and fetal mortality, and preterm birth. Previous studies indicate that lipid-apheresis may prolong pregnancy, namely heparin-mediated extracorporeal LDL-precipitation (HELP)- and dextran sulfate cellulose (DSC)-apheresis. We now report on double membrane plasmapheresis (DFPP) in early-onset preeclampsia (eoPE).
    METHODS: Open pilot study assessing the prolongation of pregnancy in PE by lipoprotein-apheresis (DRKS00004527). Two women with eoPE were treated by DFPP and compared to a historical cohort of 6 patients with eoPE treated by HELP-apheresis (NCT01967355).
    METHODS: Clinical outcome of mothers and babies and prolongation of pregnancies (time of admission to birth).
    RESULTS: Patient 1 (33y; 22 + 5/7GW) received 4 DFPP. Delivery day 19; birthweight 270 g; weight at discharge 2134 g on day 132. Patient 2 (35y; 21 + 4/7GW) received 2 DFPP. Delivery day 19; birthweight 465 g; weight at discharge 2540 g on day 104. DFPP was well tolerated by both patients.
    CONCLUSIONS: DFPP proved to be save and pregnancies remained stable as long as 19 days. Although babies were born very preterm both babies could finally be dismissed from hospital. No relevant clinical differences between DFPP and HELP-apheresis could be observed. Therefore, DFPP may extend the range of available apheresis techniques to prolong pregnancies in early-onset preeclampsia. However, further studies are necessary to gain more information.
