    目的:调查产后心血管疾病(CVD)的风险是否由妊娠期糖尿病(GDM)驱动。由GDM相关的危险因素和/或由孕前(GD前)或妊娠后糖尿病(GD后)。
    方法:在托斯卡纳分娩的妇女,2010-2012年意大利(n=74,720),从分娩时的护理证书中确定,并进一步确定为受GDM影响,通过区域管理数据库进行GD前或GD后。GDM女性,在2013-2021年期间,回顾性评估了GD前或GD后因CVD(心肌梗塞或中风;n=728)产后住院的风险,比较了患有不同形式糖尿病的女性与非糖尿病的女性。CVD风险评估为比值比(OR95%CI),在逻辑多元模型之后,将所有记录的孕前特征视为协变量.
    结果:产后CVD住院的校正OR(aOR)与GDM本身没有显着相关(aOR:0.85;0.64-1.12;p=ns),但在GD前(aOR:2.02;1.09-3.71;p=0.024)和GD后的女性中有所增加,与先前的GDM相关或不相关(aOR;4.21;2.45-7.23和分别aOR:3.80;2.38-6.05;两者的p<0.0001)。在存在孕前母亲肥胖(BMI≥30kg/m2)的情况下,CVD的aOR大约增加了一倍(aOR:1.90;1.51-2.40);p<0.0001,与GDM和GD后无关。就业妇女患CVD的调整风险较低(aOR:0.83;0.70-0.99);p=0.04,在教育水平较差的情况下显著较高(aOR:1.32;1.11-1.57);p<0.0001。
    结论:在该人群中,产后CVD的风险由GD前和GD后驱动,不仅仅是GDM。孕前肥胖是产后CVD的主要独立危险因素。
    OBJECTIVE: To investigate whether the risk for post-partum cardiovascular diseases (CVD) is driven by gestational diabetes (GDM), by GDM-related risk factors and/or by pre-gestational (Pre-GD) or post-gestational diabetes (Post-GD).
    METHODS: Women delivering in Tuscany, Italy in years 2010-2012 (n = 74,720), were identified from certificates of care at delivery and further identified as affected with GDM, Pre-GD or Post-GD through regional administrative databases. Women with GDM, Pre-GD or Post-GD were retrospectively evaluated for risk of post-partum hospitalizations for CVD (myocardial infarction or stroke; n = 728) across years 2013-2021, comparing women with different forms of diabetes to those without diabetes. Risk of CVD was assessed as odds ratio (OR 95% CI), after logistic multivariate models, considering all recorded pre-gestational characteristics as covariates.
    RESULTS: The adjusted OR (aOR) for post-partum CVD hospitalizations was not significantly related to GDM itself (aOR: 0.85; 0.64-1.12; p = ns), but increased in women with Pre-GD (aOR: 2.02; 1.09-3.71; p = 0.024) and Post-GD, associated or not to prior GDM (aOR; 4.21; 2.45-7.23 and respectively aOR: 3.80; 2.38-6.05; p < 0.0001 for both). In presence of pre-pregnancy maternal obesity (BMI ≥ 30 kg/m2) the aOR of CVD approximatively doubled (aOR: 1.90; 1.51-2.40); p < 0.0001, independently of GDM and of Post-GD. The adjusted risk of CVD was lower among employed women (aOR: 0.83; 0.70-0.99); p = 0.04 and significantly higher in presence of poorer education levels (aOR: 1.32; 1.11-1.57); p < 0.0001.
    CONCLUSIONS: In this population the risk of post-partum CVD was driven by Pre- and Post-GD, not by GDM alone. Pre-gestational obesity represented a major independent risk factor for post-partum CVD.

    目的:促性腺激素释放激素(GnRH)激动剂与GnRH拮抗剂方案在使用个体化固定日剂量的叶酸δ刺激卵巢时,如何影响卵巢反应?
    结论:BEYOND试验数据表明,在GnRH方案中使用个体化固定剂量的叶酸δ激动剂是有效的,与GnRH拮抗剂方案相比,在抗苗勒管激素(AMH)≤35pmol/l且卵巢过度刺激综合征(OHSS)风险未增加的女性中。
    背景:在使用GnRH拮抗剂方案的随机对照试验(RCTs)中已经确定了个体化固定日剂量的follitropindelta(基于体重和AMH)的有效性和安全性。初步研究数据表明,在GnRH激动剂方案中,个体化follitropindelta也是有效的(RAINBOW试验,NCT03564509)。在GnRH激动剂与GnRH拮抗剂方案中,没有使用个体化促卵泡素δ进行卵巢刺激的前瞻性比较数据。
    方法:这是第一个随机分组,控制,开放标签,多中心试验探索在接受IVF/ICSI的第一个卵巢刺激周期的参与者中,GnRH激动剂与GnRH拮抗剂方案中个体化follitropindelta给药的有效性和安全性.共有437名参与者被集中随机分配,并按中心和年龄分层。主要终点是检索到的卵母细胞数。次要终点包括持续怀孕率,药物不良反应(包括OHSS),活产,和新生儿结局。
    方法:参与者(18-40岁;AMH≤35pmol/l)在奥地利的专业生殖健康诊所注册,丹麦,以色列,意大利,荷兰,挪威,和瑞士。使用阴性二项回归模型,以筛选时的年龄和AMH为因子,比较GnRH激动剂和拮抗剂方案之间检索的卵母细胞平均数。分析基于所有随机受试者,使用多重插补方法对随机受试者在刺激开始前退出。
    结果:在437名随机受试者中,221人被随机分配给GnRH激动剂,216人被随机分配到GnRH拮抗剂方案。参与者的平均年龄为32.3±4.3岁,平均血清AMH为16.6±7.8pmol/l。在GnRH激动剂和拮抗剂组中,共有202和204名参与者开始使用follitropindelta进行卵巢刺激,分别。激动剂组(11.1±5.9)与拮抗剂组(9.6±5.5)相比,卵母细胞的平均数量在统计学上显着增加,估计平均差异为1.31个卵母细胞(95%CI:0.22;2.40,P=0.0185)。取卵数量的差异受患者年龄和卵巢储备的影响,在年龄<35岁的患者和高卵巢储备患者(AMH>15pmol/l)中观察到更大的差异。GnRH激动剂组和拮抗剂组有相似的周期取消比例(2.0%[4/202]对3.4%[7/204])和新鲜胚泡转移取消比例(13.4%[27/202]对14.7%[30/204])。GnRH激动剂组每个开始周期的估计持续妊娠率在数值上较高(36.9%对29.1%;差异:7.74%[95%CI:-1.49;16.97,P=0.1002])。最常报告的不良事件(两组均≥1%;头痛,OHSS,恶心,盆腔疼痛,或不适和腹痛)两组相似。早期中度/重度OHSS的发生率较低(激动剂组为1.5%,拮抗剂组为2.5%)。GnRH激动剂和拮抗剂组每个周期的估计活产率分别为35.8%和28.7%。治疗差异分别为7.15%;95%CI:-2.02;16.31;P=0.1265。这两个治疗组的新生儿健康数据与单胎和双胎以及先天性畸形发生率具有可比性(GnRH激动剂组和拮抗剂组分别为2.7%和3.3%,分别)。
    结论:所有参与者的AMH≤35pmol/l,年龄≤40岁。在AMH>35pmol/l(即OHSS风险增加的患者)中使用GnRH激动剂方案时,临床医生应保持谨慎。如果允许使用GnRH激动剂触发剂,则GnRH拮抗剂组中OHSS的发生率可能较低。冷冻保存的胚泡移植的结果没有随访,因此,冷冻转移后的累计活产率和新生儿结局尚不清楚.
    结论:在AMH≤35pmol/l的女性中,与GnRH拮抗剂方案相比,在GnRH激动剂方案中使用时,个体化固定日剂量的follitropindelta导致获得的卵母细胞数量显着增加,没有观察到额外的安全信号,也没有额外的OHSS风险。用个体化follitropindelta刺激卵巢后的活产率在GnRH方案之间没有统计学差异;然而,本试验的功效不足以评估该终点.在两种方案中都没有使用follitropindelta进行卵巢刺激后对新生儿健康的安全性问题。

    OBJECTIVE: How does a gonadotrophin-releasing hormone (GnRH) agonist versus a GnRH antagonist protocol affect ovarian response when using an individualized fixed daily dose of follitropin delta for ovarian stimulation?
    CONCLUSIONS: The BEYOND trial data demonstrate thatindividualized fixed-dose follitropin delta is effective when used in a GnRH agonist protocol, compared with a GnRH antagonist protocol, in women with anti-Müllerian hormone (AMH) ≤35 pmol/l and no increased risk of ovarian hyperstimulation syndrome (OHSS).
    BACKGROUND: The efficacy and safety of an individualized fixed daily dose of follitropin delta (based on body weight and AMH) have been established in randomized controlled trials (RCTs) using a GnRH antagonist protocol. Preliminary study data indicate that individualized follitropin delta is also efficacious in a GnRH agonist protocol (RAINBOW trial, NCT03564509). There are no prospective comparative data using individualized follitropin delta for ovarian stimulation in a GnRH agonist versus a GnRH antagonist protocol.
    METHODS: This is the first randomized, controlled, open-label, multi-centre trial exploring efficacy and safety of individualized follitropin delta dosing in a GnRH agonist versus a GnRH antagonist protocol in participants undergoing their first ovarian stimulation cycle for IVF/ICSI. A total of 437 participants were randomized centrally and stratified by centre and age. The primary endpoint was the number of oocytes retrieved. Secondary endpoints included ongoing pregnancy rates, adverse drug reactions (including OHSS), live births, and neonatal outcomes.
    METHODS: Participants (18-40 years; AMH ≤35 pmol/l) were enrolled at specialist reproductive health clinics in Austria, Denmark, Israel, Italy, the Netherlands, Norway, and Switzerland. The mean number of oocytes retrieved was compared between the GnRH agonist and antagonist protocols using a negative binomial regression model with age and AMH at screening as factors. Analyses were based on all randomized subjects, using a multiple imputation method for randomized subjects withdrawing before the start of stimulation.
    RESULTS: Of the 437 randomized subjects, 221 were randomized to the GnRH agonist, and 216 were randomized to the GnRH antagonist protocol. The participants had a mean age of 32.3 ± 4.3 years and a mean serum AMH of 16.6 ± 7.8 pmol/l. A total of 202 and 204 participants started ovarian stimulation with follitropin delta in the GnRH agonist and antagonist groups, respectively. The mean number of oocytes retrieved was statistically significantly higher in the agonist group (11.1 ± 5.9) versus the antagonist group (9.6 ± 5.5), with an estimated mean difference of 1.31 oocytes (95% CI: 0.22; 2.40, P = 0.0185). The difference in number of oocytes retrieved was influenced by the patients\' age and ovarian reserve, with a greater difference observed in patients aged <35 years and in patients with high ovarian reserve (AMH >15 pmol/l). Both the GnRH agonist and antagonist groups had a similar proportion of cycle cancellations (2.0% [4/202] versus 3.4% [7/204]) and fresh blastocyst transfer cancellations (13.4% [27/202] versus 14.7% [30/204]). The estimated ongoing pregnancy rate per started cycle was numerically higher in the GnRH agonist group (36.9% versus 29.1%; difference: 7.74% [95% CI: -1.49; 16.97, P = 0.1002]). The most commonly reported adverse events (≥1% in either group; headache, OHSS, nausea, pelvic pain, or discomfort and abdominal pain) were similar in both groups. The incidence of early moderate/severe OHSS was low (1.5% for the agonist group versus 2.5% for antagonist groups). Estimated live birth rates per started cycle were 35.8% and 28.7% in the GnRH agonist and antagonist groups, respectively (treatment difference 7.15%; 95% CI: -2.02; 16.31; P = 0.1265). The two treatment groups were comparable with respect to neonatal health data for singletons and twins and for incidence of congenital malformations (2.7% and 3.3% for the GnRH agonist versus antagonist groups, respectively).
    CONCLUSIONS: All participants had AMH ≤35 pmol/l and were ≤40 years old. Clinicians should remain cautious when using a GnRH agonist protocol in patients with AMH >35 pmol/l (i.e. those with an increased OHSS risk). The incidence of OHSS in the GnRH antagonist group may have been lower if a GnRH agonist trigger had been allowed. Outcomes of transfers with cryopreserved blastocysts were not followed up, therefore the cumulative live birth rates and neonatal outcomes after cryotransfer are unknown.
    CONCLUSIONS: In women with AMH ≤35 pmol/l, an individualized fixed daily dose of follitropin delta resulted in a significantly higher number of oocytes retrieved when used in a GnRH agonist protocol compared with a GnRH antagonist protocol, with no additional safety signals observed and no additional risk of OHSS. Live birth rates following ovarian stimulation with individualized follitropin delta were not statistically different between the GnRH protocols; however, the trial was not powered to assess this endpoint. There were no safety concerns with respect to neonatal health after ovarian stimulation with follitropin delta in either protocol.

    文化实践有助于在特定社区内构成“正常”的生活方式,并设定社区成员应遵守的标准。其中一些做法可能以支持青少年母亲的方式对年轻人产生短期和长期影响。这项研究探索了加纳一个研究领域的文化习俗和信仰,这些文化习俗和信仰鼓励少女无意识地成为母亲。使用了探索性设计。30名十几岁的母亲和22名意见领袖参加了2018年10月至2019年2月之间进行的实地考察。使用归纳法分析数据。四个主题变得明显:害怕因堕胎而被诅咒;睡眠安排;葬礼和唤醒;以及研究区域的同居实践。文化习俗有助于加纳阿达克卢区的青少年孕产。方案,干预措施和政策的设计应考虑到需求,上下文,和青少年的背景。未来提高青少年避免少女怀孕和孕产能力的方案应考虑家庭、人,社区,机构,以及国家和国际影响。
    Cultural practices help constitute a \'normal\' way of life within a specific community and set the standard that members of the community are expected to adhere to. Some of these practices may have a short- and long-term influence on young people in ways supportive of teenage motherhood. This study explored cultural practices and beliefs in a study area in Ghana that encourage teenage girls into motherhood unintendedly. An exploratory design was used. Thirty teenage mothers and twenty-two opinion leaders participated in fieldwork conducted between October 2018 and February 2019. Data were analysed using an inductive approach. Four themes became apparent: fear of being cursed for having an abortion; sleeping arrangements; funerals and wakes; and practices of cohabitation in the study area. Cultural practices contribute to teenage motherhood in the Adaklu District of Ghana. Programmes, interventions and policies should be designed to take into consideration the needs, contexts, and backgrounds of teenagers. Future programmes to enhance teenagers ability to avoid teenage pregnancy and motherhood should consider factors such as the family, the person, the community, institutions, and national and international influences.

    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.

    背景:先兆子痫和子痫是发病率和死亡率的常见原因,特别是在低收入国家。近年来,减少与妊娠高血压疾病相关的不良结局一直是当务之急。我们的目的是评估孕妇钙补充剂与先兆子痫和妊娠期高血压风险之间的关系。
    方法:从开始到2023年7月15日,在电子数据库中进行了系统的文献检索,仅包括随机对照试验。赔率比(OR)为,及其相应的95%置信区间(95%CI)。
    结果:总共26项研究纳入了19969名患者(9,968名患者使用钙补充剂,10,001名患者使用安慰剂组)的分析。对主要结局的汇总分析表明,钙补充剂可将先兆子痫的风险降低44%(OR,0.56(95CI:0.45-0.70),P<0.001),并将妊娠期高血压的风险降低20%(OR,0.80(95CI:0.70-0.91),P<0.001)与安慰剂相比。早产发生率有降低的趋势(OR,0.88(95CI:0.71-1.09),P=0.23),引产(或,0.90(95CI:0.78-1.03),P=0.13),小胎龄(或,0.70(95%CI:0.37,1.32),P=0.27),低出生体重(或,0.90(95CI:0.78-1.03),P=0.13),围产期死亡率(OR,0.88(95CI:0.71-1.08),P=0.22),和孕产妇死亡率(或,0.48(95CI:0.12-1.84),与安慰剂组相比,补钙组的P=0.28),然而,无法达到统计学意义。
    结论:这项研究表明,补充钙与显著降低先兆子痫和妊娠期高血压的风险相关,并有改善母婴结局的趋势。
    BACKGROUND: Pre-eclampsia and eclampsia are common causes of morbidity and mortality, especially in low-income countries. Reducing adverse outcomes associated with hypertensive disorders of pregnancy has been the ultimate priority in recent years. We aim to evaluate the association between calcium supplementation and preeclampsia and gestational hypertension risk among pregnant women.
    METHODS: A systematic literature search was performed in electronic databases from inception to 15th July 2023, including only randomized controlled trials. Odds ratio (OR) were, and their corresponding 95% confidence interval (95% CI).
    RESULTS: A total of 26 studies with 20,038 patients (10,003 patients with calcium supplements and 10,035 patients with placebo group) were included in the analysis. The Pooled analysis of primary outcome shows that calcium supplements reduce the risk of preeclampsia by 49% (OR, 0.51(95%CI: 0.40-0.66), P<0.001), and reduce the risk of gestational hypertension by 30% (OR, 0.70 (95%CI: 0.58-0.85)), P<0.001) compared to placebo. There was a trend of lower incidence of preterm delivery (OR, 0.88 (95%CI: 0.71-1.09), P=0.23), labor induction (OR, 0.90 (95%CI: 0.78-1.03), P=0.13), small for gestational age (OR, 0.70 (95% CI:0.37-1.32), P = 0.27), low birth weight (OR, 0.96 (95%CI: 0.86-1.08), P=0.53), perinatal mortality (OR, 0.88 (95%CI: 0.72-1.09), P=0.24), and maternal mortality (OR, 0.48 (95%CI: 0.12-1.84), P=0.28) among calcium supplementation group compared with the placebo group, however, statistical signifance was not achieved.
    CONCLUSIONS: This study shows that calcium supplements are associated with a significant reduction in the risk of preeclampsia and gestational hypertension and a trend toward better maternal and fetal-related outcomes.

    背景:早期子痫前期与显著的胎盘灌注不足有关。我们探讨胎盘弥散源性血管密度的诊断价值,来自扩散加权磁共振成像的生物标志物,测量体内血管微灌注,在正常和早期子痫前期妊娠的鉴别诊断中。
    方法:这是一项前瞻性研究,涉及29名对照和17名受早期先兆子痫影响的单胎妊娠。与早期先兆子痫组相比,正常组包括19例28至34周孕龄的妊娠。使用3.0T磁共振成像扫描仪,获得的扩散加权图像的扩散加权b值为0、20和40s/mm2。DDVDmean是DDVDb0b20和DDVDb0b40的平均值,而DDVDb0b20和DDVDb0b40是指从b=0和20s/mm2图像计算的扩散衍生血管密度值,从b=0和40s/mm2的图像,分别。使用线性回归模型检查DDVDmean与胎龄之间的相关性。通过接受者工作特性分析计算早期先兆子痫妊娠检测的DDVDmean曲线下面积。
    结果:随着胎龄的增加,DDVDmean线性下降。与正常妊娠相比,子痫前期早期妊娠DDVDmean显着降低(52.72±46.73对213.34±93.50au/pixel;P<0.001)。无论胎儿生长受限,区分正常和早期先兆子痫妊娠的曲线下面积(DDVDmean)为0.954,当排除无胎儿生长受限的早期先兆子痫妊娠时,曲线下面积为1.000。
    结论:DDVDmean,体内血管微灌注测量,允许正常和早期先兆子痫妊娠完全分离。
    Early preeclampsia is associated with significant placental hypoperfusion. We explore the diagnostic value of placental diffusion-derived vessel density (DDVD), a biomarker derived from diffusion-weighted magnetic resonance imaging, which measures in vivo vessel microperfusion, in the differential diagnosis of normal and early preeclampsia pregnancies.
    This was a prospective study involving 29 controls and 17 singleton pregnancies affected by early preeclampsia. Nineteen pregnancies from 28 to 34 weeks of gestational age were included from the normal group for a comparison with the early preeclampsia group. Using a 3.0 T magnetic resonance imaging scanner, diffusion-weighted images were obtained with the diffusion weighting b values of 0, 20, and 40 s/mm2. DDVDmean was the mean of DDVDb0b20 and DDVDb0b40, while DDVDb0b20 and DDVDb0b40 refer to the diffusion-derived vessel density values computed from b=0 and 20 s/mm2 images, and from b=0 and 40 s/mm2 images, respectively. The correlation between DDVDmean and gestational age was examined using a linear regression model. The area under the curve of the DDVDmean for early preeclampsia pregnancies detection was calculated by the receiver operating characteristic analysis.
    As gestational age increased, DDVDmean linearly decreased. DDVDmean was significantly decreased in the early preeclampsia pregnancies compared with the normal pregnancies (52.72±46.73 versus 213.34±93.50 au/pixel; P<0.001). The area under the curve (DDVDmean) for discriminating between normal and early preeclampsia pregnancies regardless of fetal growth restriction was 0.954, and the area under the curve was 1.000 when early preeclampsia pregnancies without fetal growth restriction were excluded.
    DDVDmean, an in vivo vessel microperfusion measure, allowed total separation of normal and early preeclampsia pregnancies.

    背景:低剂量阿司匹林治疗可降低高危孕妇先兆子痫(PE)的风险。国际上,几个前三个月的风险计算评估是可用的.
    目的:评估不同的妊娠早期PE风险估计算法的成本和收益:EXPECT(基于母体特征的算法预测模型),NICE(风险因素清单)和胎儿医学基金会(使用额外的子宫动脉多普勒测量和实验室测试的预测模型),与低剂量阿司匹林治疗相比,没有风险评估。
    方法:我们构建了一个决策分析模型,估计每个策略中的PE病例数以及PE和早期阿司匹林治疗的风险评估成本,以欧元(€)表示,在假设的100.000名女性人群中。我们进行了单向敏感性分析,以评估依从率对模型结果的影响。
    结果:预期的应用,NICE和FMF将分别导致1.98%,2.55%和1.90%的女性发展PE,相比之下,3.00%的女性在没有风险评估的情况下。总体而言,预期的净财务收益,NICE和FMF与无风险评估相比,每位患者分别为144欧元,43欧元和38欧元,分别。接受阿司匹林治疗的女性比例为18.6%,三种风险评估方法分别为10.2%和6.0%。
    结论:EXPECT和FMF在预防的PE数量方面具有可比性,并且均优于NICE或无风险评估。预计对资源的要求较低,并节省了最高的成本,但也需要最多的女性接受阿司匹林治疗。当决定哪种策略更可取时,成本节约和更容易使用必须权衡过度治疗的程度,虽然低剂量阿司匹林在怀孕期间没有明显的缺点。
    Low-dose aspirin treatment reduces the risk of preeclampsia among high-risk pregnant women. Internationally, several first-trimester risk-calculation methods are applied.
    This study aimed to assess the costs and benefits of different first-trimester preeclampsia risk estimation algorithms: EXPECT (an algorithmic prediction model based on maternal characteristics), National Institute for Health and Care Excellence (a checklist of risk factors), and the Fetal Medicine Foundation (a prediction model using additional uterine artery Doppler measurement and laboratory testing) models, coupled with low-dose aspirin treatment, in comparison with no risk assessment.
    We constructed a decision analytical model estimating the number of cases of preeclampsia with each strategy and the costs of risk assessment for preeclampsia and early aspirin treatment, expressed in euros (€) in a hypothetical population of 100,000 women. We performed 1-way sensitivity analyses to assess the impact of adherence rates on model outcomes.
    Application of the EXPECT, National Institute for Health and Care Excellence, and Fetal Medicine Foundation models results in respectively 1.98%, 2.55%, and 1.90% of the women developing preeclampsia, as opposed to 3.00% of women in the case of no risk assessment. Overall, the net financial benefits of the EXPECT, National Institute for Health and Care Excellence, and Fetal Medicine Foundation models relative to no risk assessment are €144, €43, and €38 per patient, respectively. The respective percentages of women receiving aspirin treatment are 18.6%, 10.2%, and 6.0% for the 3 risk assessment methods.
    The EXPECT and Fetal Medicine Foundation model are comparable with regard to numbers of prevented preeclampsia cases, and both are superior to the National Institute for Health and Care Excellence model and to no risk assessment. EXPECT is less resource-demanding and results in the highest cost savings, but also requires the highest number of women to be treated with aspirin. When deciding which strategy is preferable, cost savings and easier use have to be weighed against the degree of overtreatment, although low-dose aspirin has no clear disadvantages during pregnancy.

    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.

    目的:使用一种新的计算机化医疗工具能否准确且经济有效地诊断和管理早孕?
    结论:与标准临床方法相比,新医疗软件在妇科急救室的回顾性实施与更准确的诊断和更具成本效益的管理相关.
    背景:早孕并发症占咨询的比例很大,主要是在应急单位,指南变得复杂,从业者知之甚少/误解。
    方法:总共780例妇科急诊咨询(446例患者),在2018年11月至2019年6月期间在一所三级大学医院记录,被回顾性地编码在一种新的医疗计算机化工具中。纳入标准是hCG测试结果阳性,妊娠囊的超声可视化,和/或对应于14周或更小的胎龄的胚胎。新的计算机化工具建议的诊断和管理被称为eDiagnoses,而由急诊科工作人员的妇科医生提供的那些被称为medDiagnoses。
    方法:可用性是主要终点,准确性和成本降低,分别,作为二级和三级终点。相同的电子诊断/医学诊断被认为是准确的。在后续访问中,如果更新后的eDiagnoses和medDiagnoses与以前存在差异的eDiagnosis或medDiagnosis相同,以前的电子诊断或医学诊断也被认为是正确的。四位双盲专家审查了持续的差异,确定准确的诊断。使用McNemar卡方检验比较了eDiagnoses/medonses的准确性,灵敏度,特异性,和预测值。
    结果:在780份登记的医疗记录中,只有1份(0.1%)缺乏完整编码的数据。在剩下的779次磋商中,675例eDiagnoses与medDiagnoses(86.6%)相同,104例差异(13.4%)。从这104个中,60个在后续磋商中达成了协议,59例medDiagnoses最终转变为最初的eDiagnoses(98%),只有1例不同的eDiagnoses后来转变为最初的medDiagnoses(2%)。最后,在所有后续检查中,24项仍然存在差异,20项没有重新评估。在这44人中,大多数专家同意38次eDiagnoses(86%)和5次medDiagnoses(11%,包括四个双胞胎怀孕,其双胞胎是唯一的差异)。一项不一致的电子诊断/医学诊断(2%)没有达到大多数。总的来说,eDiagnoses的准确率为99.1%(779个中的675+59+38=772个eDiagnoses),与治疗诊断的87.4%(675+1+5=681)相比(P<0.0001)。计算额外咨询的所有基本费用,额外的药物,额外的手术,以及由不正确的医疗诊断与诊断引起的额外住院,新的医疗计算机化工具每月可节省3623.75欧元。回顾过去,医学计算机化工具在几乎所有记录的病例中都可用(99.9%),全球更准确(99.1%对87.4%),除了孪生报告之外的所有诊断,并且比标准临床方法更具成本效益。
    结论:回顾性研究设计是一个局限性。医疗软件的一些观察到的改进可以从具有更好超声解释的休息和/或更有经验的医师的编码中得出。该软件不能代替临床和超声检查技能,但可以提高对已发布指南的依从性。
    结论:这种医疗计算机化工具正在改进。一个新的版本考虑了多胎妊娠的诊断和管理,其特殊性(可能是多个地点,绒毛膜羊膜性)。需要进行前瞻性评估。计划进一步的发展步骤,包括将软件整合到超声设备中,并整合先前发布的预测/预后因素(例如血清孕酮,黄体评分)。
    背景:本研究未获得外部资助。F.B.和D.G.创建了新的医疗软件。

    Can early pregnancies be accurately and cost-effectively diagnosed and managed using a new medical computerized tool?
    Compared to the standard clinical approach, retrospective implementation of the new medical software in a gynaecological emergency unit was correlated with more accurate diagnosis and more cost-effective management.
    Early pregnancy complications are responsible for a large percentage of consultations, mostly in emergency units, with guidelines becoming complex and poorly known/misunderstood by practitioners.
    A total of 780 gynaecological emergency consultations (446 patients), recorded between November 2018 and June 2019 in a tertiary university hospital, were retrospectively encoded in a new medical computerized tool. The inclusion criteria were a positive hCG test result, ultrasonographical visualization of gestational sac, and/or embryo corresponding to a gestational age of 14 weeks or less. Diagnosis and management suggested by the new computerized tool are named eDiagnoses, while those provided by a gynaecologist member of the emergency department staff are called medDiagnoses.
    Usability was the primary endpoint, with accuracy and cost reduction, respectively, as secondary and tertiary endpoints. Identical eDiagnoses/medDiagnoses were considered as accurate. During follow-up visits, if the updated eDiagnoses and medDiagnoses became both identical to a previously discrepant eDiagnosis or medDiagnosis, this previous eDiagnosis or medDiagnosis was also considered as correct. Four double-blinded experts reviewed persistent discrepancies, determining the accurate diagnoses. eDiagnoses/medDiagnoses accuracies were compared using McNemar\'s Chi square test, sensitivity, specificity, and predictive values.
    Only 1 (0.1%) from 780 registered medical records lacked data for full encoding. Out of the 779 remaining consultations, 675 eDiagnoses were identical to the medDiagnoses (86.6%) and 104 were discrepant (13.4%). From these 104, 60 reached an agreement during follow-up consultations, with 59 medDiagnoses ultimately changing into the initial eDiagnoses (98%) and only one discrepant eDiagnosis turning later into the initial medDiagnosis (2%). Finally, 24 remained discrepant at all subsequent checks and 20 were not re-evaluated. Out of these 44, the majority of experts agreed on 38 eDiagnoses (86%) and 5 medDiagnoses (11%, including four twin pregnancies whose twinness was the only discrepancy). No majority was reached for one discrepant eDiagnosis/medDiagnosis (2%). In total, the accuracy of eDiagnoses was 99.1% (675 + 59 + 38 = 772 eDiagnoses out of 779), versus 87.4% (675 + 1 + 5 = 681) for medDiagnoses (P < 0.0001). Calculating all basic costs of extra consultations, extra-medications, extra-surgeries, and extra-hospitalizations induced by incorrect medDiagnoses versus eDiagnoses, the new medical computerized tool would have saved 3623.75 Euros per month. Retrospectively, the medical computerized tool was usable in almost all the recorded cases (99.9%), globally more accurate (99.1% versus 87.4%), and for all diagnoses except twinning reports, and it was more cost-effective than the standard clinical approach.
    The retrospective study design is a limitation. Some observed improvements with the medical software could derive from the encoding by a rested and/or more experienced physician who had a better ultrasound interpretation. This software cannot replace clinical and ultrasonographical skills but may improve the compliance to published guidelines.
    This medical computerized tool is improving. A new version considers diagnosis and management of multiple pregnancies with their specificities (potentially multiple locations, chorioamnionicity). Prospective evaluations will be required. Further developmental steps are planned, including software incorporation into ultrasound devices and integration of previously published predictive/prognostic factors (e.g. serum progesterone, corpus luteum scoring).
    No external funding was obtained for this study. F.B. and D.G. created the new medical software.
    NCT03993015.

    目的:减肥手术对女性的生育能力有良好的影响。然而,由于缺乏关于儿童结局的数据,减肥手术后的理想受孕时间未知.目前的指南建议在最初的减肥阶段(手术后12-24个月)避免怀孕,因为可能对后代有潜在的风险。因此,我们旨在分析接受减肥手术的母亲所生的儿童的健康状况.研究了手术至分娩间隔。
    方法:搜索了属于奥地利健康保险基金并包含健康相关数据索赔的全国注册表。分析了2010年1月至2018年12月在奥地利接受减肥手术的所有女性的数据。共有1057名妇女生了1369个孩子。根据国际疾病分类(ICD)代码和住院天数,对后代的数据进行了医疗健康索赔分析。评估了三种不同的手术至分娩间隔:12、18和24个月。
    结果:总体而言,手术后的前2年观察到421例(31%)分娩。其中,手术后12个月内有70例(5%)出生。从手术到分娩的中位时间为34个月。总的来说,在住院频率和诊断导致住院的第一年没有差异,无论手术至分娩间隔如何。
    结论:减肥手术后的头24个月怀孕是常见的。重要的是,手术至分娩间隔时间对患儿的健康结局无显著影响.
    Bariatric surgery has a favorable effect on fertility in women. However, due to a lack of data regarding children\'s outcomes, the ideal time for conception following bariatric surgery is unknown. Current guidelines advise avoiding pregnancy during the initial weight loss phase (12-24 months after surgery) as there may be potential risks to offspring. Thus, we aimed to analyze health outcomes in children born to mothers who had undergone bariatric surgery. The surgery-to-delivery interval was studied.
    A nationwide registry belonging to the Austrian health insurance funds and containing health-related data claims was searched. Data for all women who had bariatric surgery in Austria between 01/2010 and 12/2018 were analyzed. A total of 1057 women gave birth to 1369 children. The offspring\'s data were analyzed for medical health claims based on International Classification of Diseases (ICD) codes and number of days hospitalized. Three different surgery-to-delivery intervals were assessed: 12, 18, and 24 months.
    Overall, 421 deliveries (31%) were observed in the first 2 years after surgery. Of these, 70 births (5%) occurred within 12 months after surgery. The median time from surgery to delivery was 34 months. Overall, there were no differences noted in frequency of hospitalization and diagnoses leading to hospitalization in the first year of life, regardless of the surgery-to-delivery interval.
    Pregnancies in the first 24 months after bariatric surgery were common. Importantly, the surgery-to-delivery interval had no significant impact on the health outcome of the children.
