    背景:由于选择性终止(ST)不一致的双胎畸形有妊娠失败的风险,在合法的环境中可以考虑将手术推迟到妊娠晚期。
    目的:确定延迟而不是立即ST后围产期结局是否更有利。
    方法:2012年至2023年的法国多中心回顾性研究,研究了在24WG之前诊断为胎儿条件的双胎双胎ST。排除具有晚期流产的其他危险因素的妊娠。我们根据诊断出严重胎儿异常后2周内(立即ST)或等到妊娠晚期(延迟ST)的意图定义了两组。主要结果是28天的围产期生存率。次要结局是24周之前的妊娠损失和早产。
    结果:在390次怀孕中,即时ST组258例,延迟ST组132例。两组的基线特征相似。即时ST组健康双胎的总生存率为93.8%(242/258),而延迟ST组为100%(132/132)(p<0.01)。早产<37周妊娠率低于延迟ST组(66.7%vs20.2%,p<0.01);早产<28WG和<32WG没有显着差异(分别为1.7%和0.8%,p=0.66和8.26%对11.4%,p=0.36)。在延期ST组中,11.3%(15/132)因早产威胁而进行了紧急手术,其中3.7%(5/132)用于即将交付。
    结论:无论手术的胎龄如何,ST后的总生存率都很高。将ST推迟到妊娠晚期似乎可以提高生存率,而即时ST降低了早产的风险。此外,如果需要,延期ST需要一个能够在紧急情况下执行ST程序的专家中心。
    Because selective termination for discordant dichorionic twin anomalies carries a risk of pregnancy loss, deferring the procedure until the third trimester can be considered in settings where it is legal.
    To determine whether perinatal outcomes were more favorable following deferred rather than immediate selective termination.
    A French multicenter retrospective study from 2012 to 2023 on dichorionic twin pregnancies with selective termination for fetal conditions, which were diagnosed before 24 weeks gestation. Pregnancies with additional risk factors for late miscarriage were excluded. We defined 2 groups according to the intention to perform selective termination within 2 weeks after the diagnosis of the severe fetal anomaly was established (immediate selective termination) or to wait until the third trimester (deferred selective termination). The primary outcome was perinatal survival at 28 days of life. Secondary outcomes were pregnancy losses before 24 weeks gestation and preterm delivery.
    Of 390 pregnancies, 258 were in the immediate selective termination group and 132 in the deferred selective termination group. Baseline characteristics were similar in both groups. Overall survival of the healthy co-twin was 93.8% (242/258) in the immediate selective termination group vs 100% (132/132) in the deferred selective termination group (P<.01). Preterm birth <37 weeks gestation was lower in the immediate than in the deferred selective termination group (66.7% vs 20.2%; P<.01); preterm birth <28 weeks gestation and <32 weeks gestation did not differ significantly (respectively 1.7% vs 0.8%; P=.66 and 8.26% vs 11.4%; P=.36). In the deferred selective termination group, an emergency procedure was performed in 11.3% (15/132) because of threatened preterm labor, of which 3.7% (5/132) for imminent delivery.
    Overall survival after selective termination was high regardless of the gestational age at which the procedure was performed. Postponing selective termination until the third trimester seems to improve survival, whereas immediate selective termination reduces the risk of preterm delivery. Furthermore, deferred selective termination requires an expert center capable of performing the selective termination procedure on an emergency basis if required.

    目的:目的是研究妊娠28周前重度先兆子痫妇女的母婴结局。
    方法:来自三级护理中心的描述性研究。包括所有在妊娠28周前发病的重度先兆子痫(PE)的连续妇女。细节是在预先设计的结构化形式中收集的。
    结果:该研究队列包括145名妇女,平均孕产妇年龄为26.97岁±5.36(19-47)。延长妊娠的平均持续时间为13.04天±10.57(1-51天)。共有29.7%的妇女有至少一种主要的不良产妇结局,最常见的是HELLP综合征(16.6%),其次是子痫(8.3%)。死胎率高(68.7%),大多数发生在产前。在47个活着出生的婴儿中,只有八个婴儿存活到28天。FGR伴多普勒异常和新生儿败血症是围产期死亡的常见原因。
    结论:当重度PE发病在25+6周时,不应常规考虑预期治疗。在26-27+6周之间,可以在密切监测下提供,围产期存活取决于其设施中提供的新生儿服务。
    OBJECTIVE: To study the maternal and perinatal outcomes in women with severe pre-eclampsia before 28 weeks of pregnancy.
    METHODS: A descriptive study from a tertiary care center. All consecutive women with severe pre-eclampsia withonset before 28 weeks of pregnancy were included. The details were collected in a predesigned structured proforma prospectively.
    RESULTS: The study cohort included 145 women with a mean maternal age of 26.97 ± 5.36 years (range 19-47 years). The mean duration of prolongation of pregnancy was 13.04 ± 10.57 days (range 1-51 days). A total of 29.7% (n = 43) of women had at least one major adverse maternal outcome, and the most common was HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome (n = 24,16.6%), followed by eclampsia (n = 12,8.3%). The stillbirth rate was high (n = 103,68.7%), and most occurred in the antepartum period. Of 47 (31.3%) neonates born alive, only eight (17.02%;8/47) survived up to 28 days of life. Fetal growth restriction with Doppler abnormalities and neonatal sepsis were the most common reasons for perinatal mortality.
    CONCLUSIONS: Expectant management should not be considered routinely when the onset of severe pre-eclampsia is before 25+6 weeks of pregnancy. Between 26 and 27+6 weeks it can be offered under close monitoring and the perinatal survival depends on the neonatal services available in their facility.

    背景:经典的中期早产胎膜早破(PPROM)定义为妊娠28周(WG)前胎膜破裂伴羊水过少/过少;它使大约0.4-0.7%的妊娠复杂化,并与非常高的新生儿死亡率和发病率相关。抗生素在防止细菌生长方面取得的成功有限,绒毛膜羊膜炎和胎儿炎症。重复羊膜输注不起作用,因为在干预后立即失去液体。在患有经典PPROM的患者中,通过经腹系统或导管的连续羊膜输注通过冲洗羊膜腔中的细菌和炎症成分显示出希望,更换羊水,从而延长PPROM至分娩间隔。
    目的:这项多中心试验旨在测试连续羊膜输注对新生儿生存的影响,而没有典型的主要发病率。比如严重的支气管肺发育不良,脑室内出血,分娩后一年的囊性脑室周围白质软化和坏死性小肠结肠炎。
    方法:我们计划进行一项双臂平行设计的随机多中心试验。随机化将在22/0和26/0SSW之间。对照组:20/0至26/0WG之间的PPROM患者,将根据德国妇产科学会(标准PPROM治疗)的指南接受抗生素和皮质类固醇(来自22/0SSW)治疗。在介入组中,标准的PPROM治疗将补充羊膜冲洗法,通过羊膜内导管进行羊膜冲洗溶液的羊膜输注(最高100mL/h,2400mL/天)。
    方法:该研究将包括68例20/0至26/0WG之间的经典PPROM患者。

    BACKGROUND: The classic mid-trimester preterm premature rupture of membranes (PPROM) is defined as a rupture of the fetal membranes prior to 28 weeks of gestation (WG) with oligo/anhydramnion; it complicates approximately 0.4-0.7% of all pregnancies and is associated with very high neonatal mortality and morbidity. Antibiotics have limited success to prevent bacterial growth, chorioamnionitis and fetal inflammation. The repetitive amnioinfusion does not work because fluid is lost immediately after the intervention. The continuous amnioinfusion through the transabdominal port system or catheter in patients with classic PPROM shows promise by flushing out the bacteria and inflammatory components from the amniotic cavity, replacing amniotic fluid and thus prolonging the PPROM-to-delivery interval.
    OBJECTIVE: This multicenter trial aims to test the effect of continuous amnioinfusion on the neonatal survival without the typical major morbidities, such as severe bronchopulmonary dysplasia, intraventricular hemorrhage, cystic periventricular leukomalacia and necrotizing enterocolitis one year after the delivery.
    METHODS: We plan to conduct a randomized multicenter trial with a two-arm parallel design. Randomization will be between 22/0 and 26/0 SSW. The control group: PPROM patients between 20/0 and 26/0 WG who will be treated with antibiotics and corticosteroids (from 22/0 SSW) in accordance with the guidelines of German Society of Obstetrics and Gynecology (standard PPROM therapy). In the interventional group, the standard PPROM therapy will be complemented with the Amnion Flush Method, with the amnioinfusion of Amnion Flush Solution through the intra-amnial catheter (up to 100 mL/h, 2400 mL/day).
    METHODS: The study will include 68 patients with classic PPROM between 20/0 and 26/0 WG.
    BACKGROUND: ClinicalTrials.gov ID: NCT04696003.

    UNASSIGNED: To determine perinatal outcomes and influence of amniotic fluid volume in pregnancies complicated by previable, preterm prelabor rupture of membranes (pPPROM).
    UNASSIGNED: This was a historical cohort study from two tertiary-level maternity hospitals (January 1, 2009 to December 31, 2015). All pregnancies complicated by pPPROM were identified using ICD coding of discharge abstracts. Hospital charts were reviewed to collect maternal demographics, pregnancy and delivery events, and immediate postnatal outcomes (including survival). Post-processing review of stored ultrasound images was performed to evaluate the relationship between amniotic fluid volume and outcomes.
    UNASSIGNED: A total of 113 pregnancies were eligible and 99 were included in the final analysis (74 with \"expectant management\" and 25 opting for elective termination). The median gestational age at pPPROM was 20+6 weeks [IQR 19+4 to 21+5]. For those choosing expectant management, the median latency between pPPROM and delivery was 7 days, median gestational at delivery was 23+1 weeks, and neonatal survival to discharge was 27.5% overall. There was a trend towards higher rates of pregnancy termination at one hospital (31.7%) compared to the other (15.4%), but no difference between sites with respect to latency, mode of delivery, or survival amongst those managed expectantly. There was a relationship between survival and gestational age at pPPROM (p<0.04), as well as initial amniotic fluid volume category: 52.6% of survivors had normal initial amniotic fluid volumes whereas the majority of previable losses had oligohydramnios and the majority of stillbirths had anhydramnios.
    UNASSIGNED: After expectant management, more than one in four newborns following pPPROM survived to hospital discharge. While gestational age at rupture was most strongly correlated with survival, normal initial amniotic fluid volumes were mostly seen in survivors whereas stillbirths more frequently had anhydramnios. These findings will help to improve counseling and care of patients with pPPROM and in guiding long-term follow-up studies.

    Neonatal lamb and calf deaths are a major issue in UK agriculture. Consistent mortality rates over several decades, despite scientific advances, indicate that socioeconomic factors must also be understood and addressed for effective veterinary service delivery to improve lamb and calf survival. This qualitative study utilised semi-structured interviews with vets and farmers to explore the on-farm mechanisms and social context, with a particular focus on the role of the vet, to manage and reduce neonatal losses in beef calves and lambs on British farms. Data were analysed using a realist evaluation framework to assess how the mechanisms and context for veterinary service delivery influence survival as the outcome of interest. A lack of a clear outcome definition of neonatal mortality, and the financial, social and emotional impact of losses on both vets and farmers, are barriers to recording of losses and standardisation of acceptable mortality levels at a population level. Despite this, there appears to be an individual threshold on each farm at which losses become perceived as problematic, and veterinary involvement shifts from preventive to reactive mechanisms for service delivery. The veterinarian-farmer relationship is central to efforts to maximise survival, but the social and economic capital available to farmers influences the quality of this relationship. Health inequalities are well-recognised as an issue in human healthcare and the findings indicate that similar inequalities exist in livestock health systems.

    The first 28 days of aliveness are the biggest challenge mentioned for the continuity of life for children. In Ethiopia, despite a significant reduction in under-five mortality during the last 15 years, neonatal mortality remains a public health problem accounting for 47% of under-five mortality. Understanding neonatal survival and risk factors for neonatal mortality could help devising tailored interventions. The aim of this study was to determine the neonatal survival and risk factors for neonatal mortality in Aroresa district, Southern Ethiopia.
    A community based prospective follow up study was conducted among a cohort of term pregnant mothers and neonates delivered from January 1/2018 to March 30/2018. A total of 586 term pregnant mothers were selected with a multistage sampling technique and 584 neonates were followed-up for a total of 28 days, with 12 twin pairs. Data were coded, entered cleaned and analyzed using SPSS version 22. Kaplan-Meier survival curve was used to show pattern of neonatal death in 28 days. Independent and adjusted relationships of different predictors with neonates\' survival were assessed with Cox regression model. The risk of mortality was explored and presented with hazard ratio and 95% confidence interval and P-value less than 0.05 were considered as significant.
    The overall neonatal mortality was 41 per 1000 live births. Hazards of neonatal mortality was high for neonates with complications (AHR = 3.643; 95% CI, 1.36-9.77), male neonates (AHR = 2.71; 95% CI, 1.03-7.09), neonates that mothers perceived to be small (AHR = 3.46; 95% CI, 1.119-10.704), neonates who had initiated exclusive breast feeding (EBF) after 1 h (AHR = 3.572; 95% CI, 1.255-10.165) and mothers who had no postnatal care (AHR = 3.07; 95% CI, 1.16-8.12).
    Neonatal mortality in the study area was 4.1% which was high and immediate action should be taken towards achieving the Sustainable Development Goals. To improve neonatal survival, high impact interventions such as promotion of maternal service utilization, essential newborn care and early initiation of exclusive breast feeding were recommended.
