Abstract
BACKGROUND AND AIMS Severe preeclampsia increases lifetime-risk for cardiovascular disease (CVD). It remains unclear when this risk translates to subclinical atherosclerosis and whether this is related to cardiovascular health (CVH) after pregnancy. Our aims were (1) to determine CVH after severe preeclampsia, (2) to relate CVH to carotid intima-media thickness (CIMT), as a marker of subclinical atherosclerosis and (3) to relate CVH to chronological and vascular age. METHODS A prospective cohort study was performed in women with previous severe pre-eclampsia. CVH, proposed by the American Heart Association, was assessed one year after pregnancy. The CVH score (range 0-14) includes seven metrics (blood pressure, total-cholesterol, glucose, smoking, physical activity, diet and body mass index [BMI]), each weighted as poor (0), intermediate (1) or ideal (2). Vascular age was determined by CIMT. We related CVH to delta age (chronological age - vascular age). RESULTS In 244 women, the median CVH score was 10 (90% range 7.0, 13.0). Low CVH (<10) was associated with a larger CIMT than high CVH (≥12) (median 626.3 μm vs. 567.0 μm, respectively). Higher CVH was also associated with a lower vascular age (-2.0 years, 95%CI -3.3, -0.60). Women with low CVH had a larger delta age (22.5 years [90% range -3.9, 49.6) than women with high CVH (16.5 years [90% range -11.9, 43.3). CONCLUSIONS CVH is inversely related to subclinical atherosclerosis and to vascular age one year after severe preeclampsia. Especially low CVH is associated with a large difference between chronological age and vascular age. CVH counseling might provide the opportunity for timely cardiovascular prevention.

Abstract
INTRODUCTION The importance of cardiovascular health in relation to pregnancy outcome is increasingly acknowledged. Women who develop certain pregnancy complications, in particular preeclampsia, are at higher risk for future cardiovascular disease. Independent of its outcome, pregnancy requires a substantial adaptive response of the maternal cardiovascular system. In the Hemodynamic Adaptation to Pregnancy and Placenta-related Outcome (HAPPO) study, we aim to examine longitudinal maternal haemodynamic adaptation to pregnancy from the preconception period onwards. We hypothesise that women who will develop adverse pregnancy outcomes have impaired cardiovascular health before conception, leading to haemodynamic maladaptation to pregnancy and diminished uteroplacental vascular development. METHODS AND ANALYSIS In this prospective cohort study embedded in the Rotterdam periconception cohort, 200 women with a history of placenta-related pregnancy complications (high-risk group) and 100 women with an uncomplicated obstetric history (low-risk group) will be included. At five moments (preconception, first, second and third trimester and postdelivery), women will undergo an extensive examination of the macrocirculatory and microcirculatory system and uteroplacental vascular development. The main outcome measures are differences in maternal haemodynamic adaptation to pregnancy between women with and without placenta-related pregnancy complications. In a multivariate linear mixed model, the relationship between maternal haemodynamic adaptive parameters, (utero)placental vascularisation indices and clinical outcomes (occurrence of pregnancy complications, embryonic and fetal growth trajectories, miscarriage rate, gestational age at delivery, birth weight) will be studied. Subgroup analysis will be performed to study baseline and trajectory differences between high-risk and low-risk women, independent of subsequent pregnancy outcome. ETHICS AND DISSEMINATION This study protocol was approved by the Medical Ethics Committee of the Erasmus MC, Rotterdam, the Netherlands (MEC 2018-150). Results will be disseminated to the medical community by publications in peer-reviewed journals and presentations at scientific congresses. Also, patient associations will be informed and the public will be informed by dissemination through (social) media. TRIAL REGISTRATION NUMBER NL7394 (www.trialregister.nl).

Abstract
INTRODUCTION Postpartum haemorrhage (PPH) is the major cause of maternal death worldwide. Haemostatic abnormalities are independently associated with a significantly increased risk for severe PPH. In this study, the value of haemostatic evaluation in women with severe PPH was explored. AIM To investigate the occurrence of previously unknown inherited bleeding disorders in women with severe PPH. METHODS Women with severe PPH (blood loss of ≥2000 mL) between 2011 and 2017, referred to the haematology outpatient clinic for haemostatic evaluation, were retrospectively included. A bleeding disorder was diagnosed based on (inter)national guidelines, or when having a clear bleeding phenotype, not fulfilling any diagnostic criteria or laboratory abnormalities, this being classified as Bleeding of Unknown Cause (BUC). Logistic regression was used to model the association between diagnosis and obstetrical causes and risk factors for PPH. RESULTS In total, 85 women with PPH were included. In 23% (n = 16), a mild bleeding disorder was diagnosed, including low von Willebrand factor (Low VWF 8/16), platelet function disorders (PFD 5/16), BUC (2/16) and von Willebrand disease type 1 (1/16). No significant associations were found between obstetrical causes or risk factors for PPH and the presence of a bleeding disorder. CONCLUSION In 23% of women with severe PPH, a mild bleeding disorder was diagnosed, independent of obstetrical causes or risk factors for PPH. This implies that severe PPH can be the first clinical symptom of an inherited bleeding disorder. Therefore, to optimize clinical management, haemostatic evaluation after severe PPH is recommended.

Abstract
Hypertensive disorders of pregnancy (HDP), such as gestational hypertension and pre-eclampsia, affect up to 10% of all pregnancies. These women have on average a twofold higher risk to develop cardiovascular disease (CVD) later in life as compared with women with normotensive pregnancies. This increased risk might result from an underlying predisposition to CVD, HDP itself or a combination of both. After pregnancy women with HDP show an increased risk of classical cardiovascular risk factors including chronic hypertension, renal dysfunction, dyslipidemia, diabetes and subclinical atherosclerosis. The prevalence and onset of cardiovascular risk factors depends on the severity of the HDP and the coexistence of other pregnancy complications. At present, guidelines addressing postpartum cardiovascular risk assessment for women with HDP show a wide variation in their recommendations. This makes cardiovascular follow-up of women with a previous HDP confusing and non-coherent. Some guidelines advise to initiate cardiovascular follow-up (blood pressure, weight and lifestyle assessment) 6-8 weeks after pregnancy, whereas others recommend to start 6-12 months after pregnancy. Concurrent blood pressure monitoring, lipid and glucose assessment is recommended to be repeated annually to every 5 years until the age of 50 years when women will qualify for cardiovascular risk assessment according to all international cardiovascular prevention guidelines.

Abstract
It is important for healthcare professionals and pregnant women to have knowledge of the risks of using medicines during pregnancy and lactation. This not only concerns the influence of the medicinal product on the pregnant woman and the pregnancy, but also its impact on the growth and development of the (unborn) child, neonatal adaptation, possible precautions regarding child-birth, drug excretion in breast milk, and the short-term and long-term consequences for the newborn child. At present, information and advices are often fragmentary, sometimes contradictory, not easily accessible, or even not available at all. It is high time for one independent source to provide unambiguous, scientifically substantiated information and advice, accessible to both healthcare professionals and pregnant women - preferably in a digital format.

Abstract
The worldwide incidence of abnormally invasive placenta is rapidly rising, following the trend of increasing cesarean delivery. It is a heterogeneous condition and has a high maternal morbidity and mortality rate, presenting specific intrapartum challenges. Its rarity makes developing individual expertise difficult for the majority of clinicians. The International Society for Abnormally Invasive Placenta aims to improve clinicians' understanding and skills in managing this difficult condition. By pooling knowledge, experience, and expertise gained within a variety of different healthcare systems, the Society seeks to improve the outcomes for women with abnormally invasive placenta globally. The recommendations presented herewith were reached using a modified Delphi technique and are based on the best available evidence. The evidence base for each is presented using a formal grading system. The topics chosen address the most pertinent questions regarding intrapartum management of abnormally invasive placenta with respect to clinically relevant outcomes, including the following: definition of a center of excellence; requirement for antenatal hospitalization; antenatal optimization of hemoglobin; gestational age for delivery; antenatal corticosteroid administration; use of preoperative cystoscopy, ureteric stents, and prophylactic pelvic arterial balloon catheters; maternal position for surgery; type of skin incision; position of the uterine incision; use of interoperative ultrasound; prophylactic administration of oxytocin; optimal method for intraoperative diagnosis; use of expectant management; adjuvant therapies for expectant management; use of local surgical resection; type of hysterectomy; use of delayed hysterectomy; intraoperative measures to treat life-threatening hemorrhage; and fertility after conservative management.

Abstract
OBJECTIVES To develop a nationwide, evidence-based framework to support prenatal counseling in extreme prematurity, focusing on organization, decision-making, content, and style aspects. METHODS A nationwide multicenter RAND-modified Delphi method study was performed between November 2016 and December 2017 in the Netherlands. Firstly, recommendations were extracted from literature and previous studies. Secondly, an expert panel (n = 21) with experienced parents, obstetricians, and neonatologists rated the recommendations on importance for inclusion in the framework. Thirdly, ratings were discussed in a consensus meeting. The final set of recommendations was approved and transformed into a framework. RESULTS A total of 101 recommendations on organization, decision-making, content, and style were included in the framework, including tools to support personalization. The most important recommendations regarding organization were to have both parents involved in the counseling with both the neonatologist and obstetrician. The shared decision-making model was recommended for deciding between active support and comfort care. Main recommendations regarding content of conversation were explanation of treatment options, information on survival, risk of permanent consequences, impossibility to predict an individual course, possibility for multiple future decision moments, and a discussion on parental values and standards. It was considered important to avoid jargon, check understanding, and provide a summary. The expert panel, patient organization, and national professional associations (gynecology and pediatrics) approved the framework. CONCLUSIONS A nationwide, evidence-based framework for prenatal counseling in extreme prematurity was developed. It contains recommendations and tools for personalization in the domains of organization, decision-making, content, and style of prenatal counseling.

Abstract
PURPOSE The objective of present study is to determine serum levels and placental distribution of two interacting proteins calcyclin and heat shock protein 90 in preeclampsia. EXPERIMENTAL DESIGN Maternal serum levels of calcyclin and heat shock protein 90 are compared throughout pregnancy from the first trimester till term among women with preeclampsia (n = 43) and age-matched normotensive pregnant controls (n = 46). A serum-based 2D LC-MS assay using Parallel Reaction Monitoring is applied to quantify both calcyclin and heat shock protein 90. RESULTS Serum levels of calcyclin are significantly lower in patients with preeclampsia in the second trimester of pregnancy as compared to controls (p < 0.05). Serum levels of heat shock protein 90 are significantly higher in patients with preeclampsia in the third trimester as compared to controls (p < 0.001). CONCLUSION AND CLINICAL RELEVANCE Both interacting proteins calcyclin and heat shock protein 90 are notably changed in preeclamptic patients compared to controls. Calcyclin is already decreased before the onset of preeclampsia in the second trimester and HSP90 is strongly increased in the third trimester. This suggests that these proteins may play a role in the pathogenesis of preeclampsia and ought to be investigated in large cohort studies as molecular biomarkers.

Abstract
Introduction When women with a previous cesarean section and an unfavorable cervix have an indication for delivery, the choice is to induce labor or to perform a cesarean section. This study aims to assess the effectiveness and safety of a balloon catheter as a method of induction of labor in women with one previous cesarean section and an unfavorable cervix compared with an elective repeat cesarean section. Material and methods We performed a prospective cohort study in 51 hospitals in the Netherlands on term women with one previous cesarean section, a live singleton fetus in cephalic position, an unfavorable cervix and an indication for delivery. We recorded obstetric, maternal and neonatal characteristics. We compared the outcome of women who were induced with a balloon catheter with the outcome of women who delivered by elective repeat cesarean section. Main outcomes were maternal and neonatal morbidity. Mode of delivery was a secondary outcome for women who were induced. Adjusted odds ratios (aOR) were calculated using logistic regression, adjusted for potential confounders. Results Analysis was performed on 993 women who were induced and 321 women who had a repeat cesarean section (August 2011 until September 2012). Among the women who were induced, 560 (56.4%) delivered vaginally and 11 (1.1%) sustained a uterine rupture. Composite adverse maternal outcome (uterine rupture, severe postpartum hemorrhage or postpartum infection) occurred in 73 (7.4%) in the balloon and 14 (4.5%) women in the repeat cesarean section group (aOR 1.58, 95% confidence interval [CI] 0.85‐2.96). Composite adverse neonatal outcome (Apgar score <7 at 5 minutes or umbilical pH <7.10) occurred in 57 (5.7%) and 10 (3.2%) neonates, respectively (aOR 1.40, 95% CI 0.87‐3.48). Women who were induced had a shorter postpartum admission time (2.0 vs 3.0 days (P < 0.0001)). Conclusions In women with a previous cesarean section and a need for delivery, induction of labor with a balloon catheter does not result in a significant increase in adverse maternal and neonatal outcomes as compared with planned cesarean section.

Abstract
Preeclampsia increases the long-term risk of cardiovascular disease, possibly through occurrence of hypertension after delivery, such as masked hypertension, night-time hypertension, and an adverse systolic night-to-day blood pressure (BP) ratio. These types of hypertension are often unnoticed and can only be detected with ambulatory BP monitoring (ABPM). We aimed to determine hypertension prevalence and 24-hour BP pattern with ABPM and office BP measurements in women 1 year after severe preeclampsia. This is a retrospective cohort study. As part of a follow-up program after severe preeclampsia, 200 women underwent ABPM and an office BP measurement 1 year after delivery. We calculated hypertension prevalence (sustained hypertension, masked hypertension, and white-coat hypertension) and systolic night-to-day BP ratio (dipping pattern). Medical files and questionnaires provided information on preexisting hypertension and antihypertensive treatment. One year after delivery, 41.5% of women had hypertension (sustained hypertension, masked hypertension, or white-coat hypertension) with ABPM. Masked hypertension was most common (17.5%), followed by sustained hypertension (14.5%) and white-coat hypertension (9.5%). With sheer office BP measurement, only 24.0% of women would have been diagnosed hypertensive. Forty-six percent of women had a disadvantageous dipping pattern. Hypertension is common 1 year after experiencing severe preeclampsia. Masked hypertension and white-coat hypertension are risk factors for future cardiovascular disease and can only be diagnosed with ABPM. Therefore, ABPM should be offered to all these women at high risk of developing hypertension and possibly future cardiovascular disease.

Abstract
OBJECTIVES To evaluate the feasibility and effectiveness of a postpartum lifestyle intervention after pregnancies complicated by preeclampsia, fetal growth restriction (FGR) and/or gestational diabetes mellitus (GDM) to improve maternal risk factors for future cardiometabolic disease. METHODS Women following a complicated pregnancy were included six months postpartum in this specific pre-post controlled designed study. It has been conducted in one tertiary and three secondary care hospitals (intervention group) and one secondary care hospital (control group). The program consisted of a computer-tailored health education program combined with three individual counselling sessions during seven months. Primary outcome measures were the proportion of eligible women and weight change during the intervention. RESULTS Two hundred and six women were willing to participate. The proportion of eligible women who complied with the intervention was 23%. Major barrier was lack of time. Adjusted weight change attributed to lifestyle intervention was -1.9 kg (95%-CI -4.3 to -0.3). Further changes were BMI (-0.9 kg/m2 (95%-CI -1.4 to -0.3)), waist-to-hip ratio (-0.04 cm/cm (95%-CI -0.06 to -0.03)), blood pressure medication use (19% (95%-CI 9% to 28%)), HOMA2-score (59 %S (95%-CI 18 to 99)) and total fat intake (-2.9 gr (95%-CI -4.6 to -1.2)). CONCLUSIONS The results support feasibility and effectiveness of a lifestyle intervention after complicated pregnancies to improve maternal cardiometabolic risk factors. Further randomized controlled studies are needed with longer follow-up to evaluate durability. In the meantime, we suggest health care professionals to offer lifestyle interventions to women after complicated pregnancies.

Abstract
BACKGROUND Pregnancy rarely occurs in women with liver cirrhosis. However, for those who do become pregnant there are substantial maternal and foetal risks. CASE DESCRIPTION A 29-year-old pregnant woman with fully compensated liver cirrhosis was referred to a tertiary centre. No oesophageal or stomach varices were identified, nor indications for decompensation of the liver disease. Following an uneventful pregnancy, she gave (vaginal) birth at term to a healthy son. CONCLUSION The risk of complications in pregnant patients with liver cirrhosis is related to the degree of liver dysfunction and the presence of portal hypertension, emphasizing the importance of individualised preconception counselling. Oesophageal or stomach variceal bleeding during pregnancy carries a considerable risk of mortality. Therefore, screening endoscopy in the second trimester is advised to facilitate primary prophylaxis of variceal bleeding. Although the risk of variceal bleeding is increased during delivery, elective caesarean sections are not routinely performed because of an increased risk of bleeding due to abdominal wall varices. Pregnant women with liver cirrhosis should ideally be managed in a tertiary centre and in a multidisciplinary setting, to include input from a gynaecologist and gastroenterologist/hepatologist.

Abstract
OBJECTIVES To assess the evolution of the soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) ratio in women with suspected or confirmed pre-eclampsia (PE), and to investigate the changes in sFlt-1 and PlGF levels in pre-eclamptic women after delivery. METHODS This was an exploratory study in which secondary analysis was performed on a prospective cohort study that enrolled women with a singleton pregnancy and suspected or confirmed PE from 18 weeks' gestation, carried out between December 2013 and April 2016 at the Department of Obstetrics of the Erasmus Medical Center in Rotterdam. sFlt-1 and PlGF were determined using Roche Diagnostics Elecsys assays in two groups of patients. In the first group, patients with suspected or confirmed PE had sFlt-1 and PlGF levels measured at least twice during their pregnancy. Changes in these biomarkers over the course of pregnancy were compared for patients in this group with a baseline sFlt-1/PlGF ratio of ≤ 38 and for those with a ratio > 38. In the second group, sFlt-1 and PlGF levels of women with PE or HELLP syndrome were measured before and after delivery. For this group, pre- and postpartum sFlt-1 and PlGF levels were compared and half-lives were calculated. RESULTS Women with suspected or confirmed PE for whom sFlt-1 and PlGF levels were measured at least twice during pregnancy (n = 46) had a median gestational age at inclusion of 26 weeks (range, 18-40 weeks). In 27 of the 30 patients with sFlt-1/PlGF ratio ≤ 38 at baseline, thereby ruling out PE, the sFlt-1/PlGF ratio remained stable for up to 100 days. In the remaining three patients with a ratio ≤ 38 and in most of the 16 patients with a ratio > 38, the ratio increased further. For women diagnosed with PE or HELLP syndrome for whom sFlt-1 and PlGF levels were measured before and after delivery (n = 26), median gestational age at inclusion was 29 weeks (range, 16-37 weeks) and median time between antepartum measurement and delivery was 2 days (range, 1-17 days). In this group, after delivery, sFlt-1 dropped to < 1% of its pre-delivery value, with a half-life of 1.4 ± 0.3 days, while PlGF dropped to ∼30% of its pre-delivery value, with a half-life of 3.7 ± 4.3 days. CONCLUSIONS Based on this small cohort, up to 10% of pregnant women admitted with suspected or confirmed PE presenting with a sFlt-1/PlGF ratio of ≤ 38 display a rise in sFlt-1/PlGF ratio in subsequent weeks, implying that repeat determination of the sFlt-1/PlGF ratio is required to exclude definitively a diagnosis of PE. Furthermore, the rapid and pronounced decline in sFlt-1 levels after delivery in patients with PE/HELLP syndrome suggests that sFlt-1, in contrast to PlGF, is almost entirely derived from the placenta.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of combining cervical-length (CL) measurement and fetal fibronectin (fFN) testing in women with symptoms of preterm labor between 24 and 34 weeks' gestation. METHODS This was a model-based cost-effectiveness analysis evaluating seven test-treatment strategies based on CL measurement and/or fFN testing in women with symptoms of preterm labor from a societal perspective, in which neonatal outcomes and costs were weighted. Estimates of disease prevalence, test accuracy and costs were based on two recently performed nationwide cohort studies in The Netherlands. RESULTS Strategies using fFN testing and CL measurement separately to predict preterm delivery are associated with higher costs and incidence of adverse neonatal outcomes compared with strategies that combine both tests. Additional fFN testing when CL is 15-30 mm was considered cost effective, leading to a cost saving of €3919 per woman when compared with a treat-all strategy, with a small deterioration in neonatal health outcomes, namely one additional perinatal death and 21 adverse outcomes per 10 000 women with signs of preterm labor (incremental cost-effectiveness ratios €39 million and €1.9 million, respectively). Implementing this strategy in The Netherlands, a country with about 180 000 deliveries annually, could lead to an annual cost saving of between €2.4 million and €7.6 million, with only a small deterioration in neonatal health outcomes. CONCLUSION In women with symptoms of preterm labor at 24-34 weeks' gestation, performing additional fFN testing when CL is between 15 and 30 mm is a viable and cost-saving strategy.

Abstract
BACKGROUND Although the levonorgestrel-releasing intrauterine device (LNG-IUD) is one of the most reliable methods of contraception, it is associated with an increased risk of ectopic pregnancy in case of unintended pregnancy. A rare form of ectopic pregnancy is the caesarean scar pregnancy (CSP), with a high risk of serious maternal morbidity, such as uterine rupture, massive haemorrhage and resulting infertility. This report describes the first case of a viable CSP at 13 weeks of gestation in association with the use of a LNG-IUD. Case-presentation: A 36-year-old Caucasian woman was referred to our outpatient clinic because of suspicion of a CSP. The pregnancy was unintended and was diagnosed during replacement of the LNG-IUD after five years. The patient had undergone two caesarean sections in the past. Ultrasound investigation showed an intact pregnancy of approximately 13 weeks of gestation located in the uterine scar. Because of the size of the gestational sac, a laparotomy was performed under general anaesthesia using a Joel-Cohen incision. The procedure was complicated by a total blood loss of 1500 mL, mostly caused by diffuse bleeding from the placental bed. CONCLUSION Unintended pregnancies in women using a LNG-IUD are frequently ectopic pregnancies with a preponderance to nidate outside the fallopian tube. Therefore, early diagnosis and location of the pregnancy in women using a LNG-IUD is essential.

Abstract
Objective To provide evidence to support updated guidelines for the management of pregnant women with hereditary thrombophilia in order to reduce the risk of a first venous thromboembolism (VTE) in pregnancy.Design Systematic review and bayesian meta-analysis.Data sources Embase, Medline, Web of Science, Cochrane Library, and Google Scholar from inception through 14 November 2016.Review methods Observational studies that reported on pregnancies without the use of anticoagulants and the outcome of first VTE for women with thrombophilia were eligible for inclusion. VTE was considered established if it was confirmed by objective means, or when the patient had received a full course of a full dose anticoagulant treatment without objective testing. Results 36 studies were included in the meta-analysis. All thrombophilias increased the risk for pregnancy associated VTE (probabilities ≥91%). Regarding absolute risks of pregnancy associated VTE, high risk thrombophilias were antithrombin deficiency (antepartum: 7.3%, 95% credible interval 1.8% to 15.6%; post partum: 11.1%, 3.7% to 21.0%), protein C deficiency (antepartum: 3.2%, 0.6% to 8.2%; post partum: 5.4%, 0.9% to 13.8%), protein S deficiency (antepartum: 0.9%, 0.0% to 3.7%; post partum: 4.2%; 0.7% to 9.4%), and homozygous factor V Leiden (antepartum: 2.8%, 0.0% to 8.6%; post partum: 2.8%, 0.0% to 8.8%). Absolute combined antepartum and postpartum risks for women with heterozygous factor V Leiden, heterozygous prothrombin G20210A mutations, or compound heterozygous factor V Leiden and prothrombin G20210A mutations were all below 3%. Conclusions Women with antithrombin, protein C, or protein S deficiency or with homozygous factor V Leiden should be considered for antepartum or postpartum thrombosis prophylaxis, or both. Women with heterozygous factor V Leiden, heterozygous prothrombin G20210A mutation, or compound heterozygous factor V Leiden and prothrombin G20210A mutation should generally not be prescribed thrombosis prophylaxis on the basis of thrombophilia and family history alone. These data should be considered in future guidelines on pregnancy associated VTE risk.

Abstract
BACKGROUND In this study we determined the outcome of subsequent pregnancies after termination of pregnancy for preeclampsia, with the purpose of presenting data useful for counselling these women on future pregnancies. STUDY DESIGN The cohort consisted of 131 women with a history of termination of pregnancy for preeclampsia. RESULTS Data of 79 pregnancies were available for analysis, including 13 women with chronic hypertension and 16 women with thrombophilia. There were seven miscarriages (8.8%) and 72 ongoing pregnancies. Low-dose aspirin was prescribed for 64 women (89%). The mean gestational age at delivery was 356/7 ± 4 weeks with a mean birth weight of 2571 ± 938 g. Overall recurrence rate for preeclampsia was 29% at a mean gestational age of 32 weeks. Thirty-eight women had an uncomplicated pregnancy (53%). The women with chronic hypertension had the highest recurrence rate of 38%. Neonatal mortality was 4%. CONCLUSION The course of subsequent pregnancies after mid-trimester termination for preeclampsia is uncomplicated in 53% with a recurrence rate for preeclampsia of 29%. The mean gestational age at delivery was 11 weeks later and birth weight 2000 g higher than in the index pregnancy.

Abstract
OBJECTIVES To explore whether, in early fetal growth restriction (FGR), the longitudinal pattern of fetal heart rate (FHR) short-term variation (STV) can be used to identify imminent fetal distress and whether abnormalities of FHR recordings are associated with 2-year infant outcome. METHODS The original TRUFFLE study assessed whether, in early FGR, delivery based on ductus venosus (DV) Doppler pulsatility index (PI), in combination with safety-net criteria of very low STV on cardiotocography (CTG) and/or recurrent FHR decelerations, could improve 2-year infant survival without neurological impairment in comparison with delivery based on CTG monitoring only. This was a secondary analysis of women who delivered before 32 weeks and had consecutive STV data recorded > 3 days before delivery and known infant outcome at 2 years of age. Women who received corticosteroids within 3 days of delivery were excluded. Individual regression line algorithms of all STV values, except the last one before delivery, were calculated. Life tables and Cox regression analysis were used to calculate the daily risk for low STV or very low STV and/or FHR decelerations (below DV group safety-net criteria) and to assess which parameters were associated with this risk. Furthermore, it was assessed whether STV pattern, last STV value or recurrent FHR decelerations were associated with 2-year infant outcome. RESULTS One hundred and forty-nine women from the original TRUFFLE study met the inclusion criteria. Using the individual STV regression lines, prediction of a last STV below the cut-off used by the CTG monitoring group had sensitivity of 42% and specificity of 91%. For each day after study inclusion, the median risk for low STV (CTG group cut-off) was 4% (interquartile range (IQR), 2-7%) and for very low STV and/or recurrent FHR decelerations (below DV group safety-net criteria) was 5% (IQR, 4-7%). Measures of STV pattern, fetal Doppler (arterial or venous), birth-weight multiples of the median and gestational age did not usefully improve daily risk prediction. There was no association of STV regression coefficients, a low last STV and/or recurrent FHR decelerations with short- or long-term infant outcomes. CONCLUSION The TRUFFLE study showed that a strategy of DV monitoring with safety-net criteria of very low STV and/or recurrent FHR decelerations for delivery indication could increase 2-year infant survival without neurological impairment. This post-hoc analysis demonstrates that, in early FGR, the daily risk of abnormal CTG, as defined by the DV group safety-net criteria, is 5%, and that prediction is not possible. This supports the rationale for CTG monitoring more often than daily in these high-risk fetuses. Low STV and/or recurrent FHR decelerations were not associated with adverse infant outcome and it appears safe to delay intervention until such abnormalities occur, as long as DV-PI is within normal range.

Abstract
OBJECTIVES In the recent TRUFFLE study, it appeared that, in pregnancies complicated by fetal growth restriction (FGR) between 26 and 32 weeks' gestation, monitoring of the fetal ductus venosus (DV) waveform combined with computed cardiotocography (CTG) to determine timing of delivery increased the chance of infant survival without neurological impairment. However, concerns with the interpretation were raised, as DV monitoring appeared to be associated with a non-significant increase in fetal death, and some infants were delivered after 32 weeks, at which time the study protocol no longer applied. This secondary sensitivity analysis of the TRUFFLE study focuses on women who delivered before 32 completed weeks' gestation and analyzes in detail the cases of fetal death. METHODS Monitoring data of 317 pregnancies with FGR that delivered before 32 weeks were analyzed, excluding those with absent outcome data or inevitable perinatal death. Women were allocated randomly to one of three groups of indication for delivery according to the following monitoring strategies: (1) reduced fetal heart rate short-term variation (STV) on CTG; (2) early changes in fetal DV waveform; and (3) late changes in fetal DV waveform. Primary outcome was 2-year survival without neurological impairment. The association of the last monitoring data before delivery and infant outcome was assessed by multivariable analysis. RESULTS Two-year survival without neurological impairment occurred more often in the two DV groups (both 83%) than in the CTG-STV group (77%), however, the difference was not statistically significant (P = 0.21). Among the surviving infants in the DV groups, 93% were free of neurological impairment vs 85% of surviving infants in the CTG-STV group (P = 0.049). All fetal deaths (n = 7) occurred in the groups with DV monitoring. Of the monitoring parameters obtained shortly before fetal death in these seven cases, an abnormal CTG was observed in only one case. Multivariable regression analysis of factors at study entry demonstrated that a later gestational age, higher estimated fetal weight-to-50th percentile ratio and lower umbilical artery pulsatility index (PI)/fetal middle cerebral artery-PI ratio were significantly associated with normal outcome. Allocation to DV monitoring had a smaller effect on outcome, but remained in the model (P < 0.1). Abnormal fetal arterial Doppler before delivery was significantly associated with adverse outcome in the CTG-STV group. In contrast, abnormal DV flow was the only monitoring parameter associated with adverse outcome in the DV groups, while fetal arterial Doppler, STV below the cut-off used in the CTG-STV group and recurrent decelerations in fetal heart rate were not. CONCLUSIONS In accordance with the findings of the TRUFFLE study on monitoring and intervention management of very preterm FGR, we found that the proportion of infants surviving without neuroimpairment was not significantly different when the decision for delivery was based on changes in DV waveform vs reduced STV on CTG. The uneven distribution of fetal deaths towards the DV groups was probably a chance effect, and neurological outcome was better among surviving children in these groups. Before 32 weeks, delaying delivery until abnormalities in DV-PI or STV and/or recurrent decelerations in fetal heat rate occur, as defined by the study protocol, is likely to be safe and possibly benefits long-term outcome.

Abstract
Red cells play a key role in normal haemostasis in vitro but their importance clinically is less clear. The objective of this meta-analysis was to assess if correction of anaemia by transfusing red cells at a high haemoglobin threshold (liberal transfusion) is superior to transfusion at a lower haemoglobin threshold (restrictive transfusion) for reducing the risk of bleeding or thrombotic events. We searched for randomised controlled trials in any clinical setting that compared two red cell transfusion thresholds and investigated the risk of bleeding. We searched for studies published up to October 19, 2016 in The Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, Embase, and the Transfusion Evidence Library and ISI Web of Science. Relative risks (RR) or Peto Odds Ratios (pOR) were pooled using a random-effect model. Nineteen randomised trials with 9852 participants were eligible for inclusion in this review. Overall there was no difference in the risk of any bleeding between transfusion strategies (RR 0.91, 95 % confidence interval [CI] 0.74 to 1.12). The risk of severe or life-threatening bleeding was lower with a restrictive strategy (RR 0.75, 95 % CI 0.57 to 0.99). There was no difference in the risk of thrombotic events (RR 0.83, 95 % CI 0.61 to 1.13). The risk of any bleeding was not reduced with liberal transfusion and there was no overall difference in the risk of thrombotic events. Data from the included trials do not support aiming for a high haemoglobin threshold to improve haemostasis. PROSPERO registration number CRD42016035519.

Abstract
INTRODUCTION Turner syndrome (TS) is associated with subfertility and infertility. Nevertheless, an increasing number of women become pregnant through oocyte donation. The wish to conceive may be negatively influenced by the fear of cardiovascular complications. The aim was to investigate the wish to conceive and the concerns about cardiovascular complications during pregnancy in women with TS. METHODS The patient association for TS invited all members of ≥18 years old (n = 344) to complete a specifically developed, disease-specific questionnaire, including questions about fertility, wish to conceive, attempts and concerns. Results were compared with previously published results of this questionnaire in women with congenital heart disease. RESULTS The questionnaire was completed by 89 women (median age 30.1 years, Q1-Q3 = 22.9-39.4). Of them, 51% had 45, X0-monosomy and 38% had ≥1 cardiac abnormality. Seventeen women (19%) had attempted to become pregnant and 12 of them succeeded to become pregnant. Women who had not undertaken attempts to conceive (81%), considered themselves mainly too young or had no partner. Of the total sample, 58% were concerned about the influence of pregnancy on their cardiovascular status. This was higher (75%) in the sample of women with TS and cardiac abnormalities, than in women with congenital heart disease from a previously published cohort (21%), (p < .001). There were no differences in concerns about pregnancy complications between women with TS who respectively had or had not attempted to become pregnant. DISCUSSION Women with TS, especially those with cardiac abnormalities, show serious concerns about the risks pregnancy may have. Patients should be timely counseled and specifically asked about their concerns. Psychosocial care should be provided when necessary.

Abstract
Objective We assessed the influence of external factors on false-positive, false-negative, and invalid fibronectin results in the prediction of spontaneous delivery within 7 days. Methods We studied symptomatic women between 24 and 34 weeks' gestational age. We performed uni- and multivariable logistic regression to estimate the effect of external factors (vaginal soap, digital examination, transvaginal sonography, sexual intercourse, vaginal bleeding) on the risk of false-positive, false-negative, and invalid results, using spontaneous delivery within 7 days as the outcome. Results Out of 708 women, 237 (33%) had a false-positive result; none of the factors showed a significant association. Vaginal bleeding increased the proportion of positive fetal fibronectin (fFN) results, but was significantly associated with a lower risk of false-positive test results (odds ratio [OR], 0.22; 95% confidence intervals [CI], 0.12-0.39). Ten women (1%) had a false-negative result. None of the investigated factors was significantly associated with a significantly higher risk of false-negative results. Twenty-one tests (3%) were invalid; only vaginal bleeding showed a significant association (OR, 4.5; 95% CI, 1.7-12). Conclusion The effect of external factors on the performance of qualitative fFN testing is limited, with vaginal bleeding as the only factor that reduces its validity.
