Abstract
Our study aimed to investigate the clinical features of recurrent preeclampsia (rPE) and evaluate the preventive effect of low-dose aspirin (LDA) in rPE. We retrospectively analyzed the data of 109 patients who experienced preeclampsia in two consecutive pregnancies and delivered at Peking University First Hospital from January 2016 to December 2022. We analyzed the pregnancy outcomes of patients with rPE and assessed whether the use of LDA during pregnancy could improve these outcomes. Our results revealed that patients with rPE had a higher body mass index (BMI) and a higher incidence of diabetes during pregnancy compared to their first onset of preeclampsia (29.01 ± 4.70 kg/m2 vs. 27.13 ± 4.25 kg/m2, P < 0.05; 11.01% vs. 1.83%, P < 0.05). Furthermore, the incidence of severe preeclampsia was higher at recurrence in patients with rPE compared to their first onset (83.49% vs. 70.64%, P < 0.05), as well as the incidence of severe preeclampsia with chronic hypertension (34.86% vs. 8.26%, P < 0.05). Additionally, the incidence of gestational diabetes and postpartum hemorrhage was higher in patients with rPE compared to their first preeclampsia onset (25.69% vs. 5.50%, P < 0.05; 20.18% vs. 5.83%, P < 0.05). Compared to the first onset of preeclampsia, patients with rPE had an earlier gestational age at delivery (35.42 ± 3.06 weeks vs. 36.60 ± 2.74 weeks, P < 0.05), lower birth weight of neonates (2478.39 ± 828.44 g vs. 2883.71 ± 712.94 g, P < 0.05), and a higher risk of premature birth (67.00% vs. 47.19%, P < 0.05). However, in patients with rPE, the use of LDA delayed the gestational age at delivery, increased the birth weight of the neonate, reduced the premature birth rate, and increased the perinatal survival rate. In conclusion, patients with rPE are at an increased risk of adverse maternal and fetal outcomes. However, the use of LDA during pregnancy effectively improves these outcomes.

Abstract
OBJECTIVE Compare the clinical severity of second preeclampsia with the first preeclampsia. METHODS This retrospective longitudinal cohort study was conducted in three teaching hospitals in Guangzhou, where there were a total of 296 405 deliveries between 2010 and 2021. Two consecutive singleton deliveries complicated with preeclampsia were included. Clinical features, laboratory results within 1 week before delivery, and maternal and neonatal outcomes of both deliveries were collected. Univariate analyses were made using paired Wilcoxon tests and McNemar tests. Multivariable logistic regression and generalized linear models were performed to assess the association of adverse maternal and neonatal outcomes with second preeclampsia. RESULTS A total of 151 women were included in the study. The mean maternal age was 28 and 33 years for the first and second deliveries, respectively. The proportion of preventive acetylsalicylic acid use was 4.6% for the first delivery and 15.2% for the second delivery. No significant differences were observed in terms of blood pressure on admission, gestational weeks of admission and delivery, application of perinatal antihypertensive agents, rates of preterm delivery, and severe features between the two occurrences. However, the rates of heart disease, edema, and admission to the ICU were lower, and hospital stays were shorter in the second preeclampsia compared with the first preeclampsia. Sensitivity analysis conducted among women who did not use preventive acetylsalicylic acid yielded similar results. After adjusting for potential confounding variables, the occurrence of second preeclampsia was associated with significantly decreased risks of heart disease, edema, complications, and admission to the NICU, with odds ratios ranging between 0.157 and 0.336. CONCLUSION Contrary to expectations, the second preeclampsia did not exhibit worse manifestations or outcomes to the first occurrence. In fact, some clinical features and outcomes appeared to be better in the second preeclampsia.

Abstract
OBJECTIVES We aim to establish a predictive model for recurrent preeclampsia. METHODS A retrospective review of medical records from three hospitals between 2010 and 2021 was conducted. The study included women who had two consecutive singleton deliveries at the same hospital, with the first delivery complicated by preeclampsia. A multivariable logistic regression model was constructed using a training cohort, and subsequently cross-validated and tested using an independent cohort. The model's performance was assessed in terms of discrimination and calibration, and its clinical utility was evaluated using decision curve analysis (DCA). RESULTS Among 296 405 deliveries, 694 women met the inclusion criteria, with 151 (21.8%) experiencing recurrent preeclampsia. The predictive model incorporated 10 risk factors from previous preeclampsia, including gestational weeks with elevated blood pressure, gestational diabetes mellitus (GDM), pericardial effusion, heart failure, limb edema, serum creatinine, white blood cell count, low platelet counts within one week before delivery, SBP on the first postpartum day, and postpartum antihypertensive use. Additionally, one risk factor from the index pregnancy was included, which was antihypertensive use before 20 weeks. The model demonstrated better discrimination, calibration, and a net benefit across a wide range of recurrent preeclampsia risk thresholds. Furthermore, the model has been translated into a clinical risk calculator, enabling clinicians to calculate individualized risks of recurrent preeclampsia. CONCLUSION Our study demonstrates that a predictive tool utilizing routine clinical and laboratory factors can accurately estimate the risk of recurrent preeclampsia. This predictive model has the potential to facilitate shared decision-making by providing personalized and risk-stratified care.

Abstract
In the recent decades, endothelial dysfunction (ED) has been recognized as a significant contributing factor in the pathogenesis of many pathological conditions. In interaction with atherosclerosis, hypercholesterolemia, and hypertension, ED plays a crucial role in the pathogenesis of coronary artery disease, chronic renal disease, and microvascular complications in diabetes mellitus. Although ED plays a significant role in the pathogenesis of several pregnancy-related disorders such as preeclampsia, HELLP syndrome, fetal growth restriction, and gestational diabetes mellitus, the exact pathogenetic mechanisms are still a matter of debate. The increased prevalence of these entities in patients with preexisting vascular diseases highlights the essential pathological role of the preexisting ED in these patients. The abnormal uteroplacental circulation and the release of soluble factors from the ischemic placenta into the maternal bloodstream are the main causes of the maternal ED underlying the characteristic preeclamptic phenotype. Besides the increased risk for maternal and fetal poor outcomes, the preexisting ED also increases the risk of development of future cardiovascular diseases in these patients. This study aimed to look deeper into the role of ED in the pathogenesis of several pregnancy-related hypertensive and liver diseases. Hopefully, it could contribute to improvement of the awareness, knowledge, and management of these conditions and also to the reduction of the adverse outcomes and additional long-term cardiovascular complications.

Abstract
The management of pregnant women with thrombophilia and a history of gestational vascular complications remains debatable. Treatment of the latter is often based on clinical outcome rather than disease mechanism. While the use of venous thromboembolism prophylaxis in pregnancy is recommended for those at increased risk, the ability of anticoagulant and/or antiplatelet agents to lower the risk of placenta-mediated complications in this clinical setting remains controversial. The available guidelines are inconsistent in some situations, which reflects the limited evidence base. This review critically discusses risk assessment models (RAMs) and management strategies of women with thrombophilia and pregnancy complications, using clinical vignettes. RAMs, taking into account obstetric and thrombotic history as well as thrombophilia status, could drive a precision medicine approach, based on disease mechanism, and guide individual therapeutic interventions in high-risk clinical settings.

Abstract
Preterm birth is the leading cause of perinatal morbidity and mortality in developed countries. Common reasons for indicated preterm births include pre-eclampsia. The increase in incidences of morbidity and mortality observed in neonates resulting from pregnancies complicated by preeclampsia is also due to alterations in angiogenic and pro-inflammatory factors that directly affect the neonatal health. This review was prepared with the aim of gathering the information available at PubMed/MEDLINE, in the years from 2011 to 2021, on the consequences of neonatal morbidity and mortality of early-onset preeclampsia. There is great controversy in the literature and paucity of studies. Early onset pre-eclampsia has been linked to fetal growth restriction (FGR). Most studies support its association with respiratory distress syndrome (RDS). Most studies point to an association between preeclampsia and bronchopulmonary dysplasia (BPD), with the highest risk in FGR. The association between preeclampsia, patent ductus arteriosus (PDA) and sepsis is not supported by the literature. The association to necrotizing enterocolitis (NEC) is controversial. The risk of spontaneous intestinal perforation (SIP) seems to be increased with preeclampsia. The association between intraventricular hemorrhage (IVH) and preeclampsia is controversial, however, preeclampsia seems to have a protective effect on periventricular leukomalacia (PVL). Most of the evidence points to the non-association between preeclampsia and retinopathy of prematurity (ROP). Hematological changes such as neutropenia, thrombocytopenia and increased nucleated red blood cell counts have been shown to be associated with preeclampsia. The evidence is still quite controversial regarding mortality. The early installation of preeclampsia will have direct consequences on neonatal morbidity. Gestational age at preterm birth is the main risk factor on neonatal morbidity. Obstetricians should aim to prolong the pregnancies complicated by early-onset severe preeclampsia as far as maternal conditions allow. This policy may contribute to improve the neonatal outcomes.

Abstract
We previously showed that masked hypertension is a frequent finding in high-risk pregnancies and a strong predictor of preeclampsia/eclampsia. However, neonatal consequences of masked hypertension have not been deeply analyzed. Consequently, the aim of this study was to determine if masked hypertension is a risk factor for poor neonatal outcome. We evaluated a cohort of 588 high-risk pregnant women (29 ± 7 years old with 27 ± 6 weeks of gestation at blood pressure evaluation); 22.1%, 8.5%, 2.9%, and 2.6% had history of hypertension, diabetes, collagen diseases and chronic renal disease, respectively. According to the data of office and ambulatory blood pressures monitoring, women was classified as normotension (61.7%), white-coat hypertension (5.4%), masked hypertension (21.6%) and sustained hypertension (11.2%) respectively. Compared to normotension, all neonatal outcomes were worst in women with masked hypertension; neonates had lower mean birth weight (2577 (842) vs. 3079 (688) g, P < 0.001), higher prevalence of very low (12.1% vs 2.0%, P = .002) and extremely low birth weight (4.3% vs 0%, P < 0.001), and low one-minute APGAR score (7.8% vs 1.8%, P < 0.001). Furthermore, 14.2% needed admission to neonatal intensive care unit (NICE) (P = 0.001). Compared with normotension the risk for poor the combined neonatal outcome (admission to NICE plus still born) was significantly higher in masked hypertension (adjusted OR 2.58 95% CI 1.23-5.40) but not in white-coat hypertension (adjusted OR 0.41 95% CI 0.05-3.12). In conclusion, in high-risk pregnancies, masked hypertension was a strong and independent predictor for poor neonatal outcomes.

Abstract
Preeclampsia (PE) is a leading condition threatening pregnant women and their offspring. The offspring of PE pregnancies have a high risk of poor neurodevelopmental outcomes and neuropsychological diseases later in life. However, the pathophysiology and pathogenesis of poor neurodevelopment remain undetermined. Abnormal placental functions are at the core of most PE cases, and recent research evidence supports that the placenta plays an important role in fetal brain development. Here, we summarize the relationship between abnormal fetal brain development and placental dysfunction in PE conditions, which include the dysfunction of nutrient and gas-waste exchange, impaired angiogenesis stimulation, abnormal neurotransmitter regulation, disrupted special protectors, and immune disorders. All these factors could lead to poor neurodevelopmental outcomes.

Abstract
Background Preeclampsia is a multisystem disorder characterized by an abnormal vascular response to placentation associated with increased systemic vascular resistance. As liver involvement is one of the main clinical features of preeclampsia, we sought to determine if there is an association between chronic liver diseases and preeclampsia. Methods A retrospective matched case–control analysis was conducted in a tertiary medical center. Three hundred eleven (311) pregnant women with preexisting chronic liver disease (study group), including viral and autoimmune hepatitis, non-alcoholic fatty liver, Wilson disease, and cirrhosis, were match for age, parity, and number of fetuses to 933 healthy pregnant women (control group). The primary outcome measure was the incidence of preeclampsia in each group. Secondary outcome measures were obstetrical and neonatal complications. Confounders found to be significant on univariate analysis were evaluated using logistic regression models, and odds ratios (OR) and confidence intervals (CI) were calculated. Results Preeclampsia was diagnosed in 28 women (9.0%) in the study group and 33 women (3.54%) in the control group (p < 0.001). On multivariate analysis adjusted for maternal age, parity, previous preeclampsia, chronic hypertension, gestational diabetes mellitus, pregestational diabetes mellitus, antiphospholipid syndrome, and mode of conception, chronic liver disease was found to be an independent risk factor for preeclampsia (aOR 2.631, 95% CI 1.518–4.561). Although there was no difference in the gestational week at delivery between the groups (38.6 ± 2.13 vs. 38.8 ± 2.17 for study and control group, respectively, p = 0.410), the study group had a lower mean neonatal birthweight (3088 ± 551 vs. 3182 ± 566 g, p = 0.011). There were no between-group differences in the other parameters evaluated. Conclusion In our study, preexisting chronic liver disease was associated with a 2.6-fold increased risk of preeclampsia.

Hypertensive Disorders during Pregnancy and Anthropometric Measurement of Children up to 7 Years of Age: The Hokkaido Birth Cohort Study in Japan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182010951. [PMID: 34682697 PMCID: PMC8536157 DOI: 10.3390/ijerph182010951] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 09/22/2021] [Accepted: 10/15/2021] [Indexed: 12/17/2022]
Abstract
Hypertensive disorders during pregnancy (HDP) increase the risk of offspring with a low birth weight, preterm birth and small-for-gestational age; however, evidence of the anthropometric measurements during early childhood remains limited. We aimed to understand the associations between maternal HDP and anthropometric measurements of children aged up to seven years in a Japanese cohort. In total, 20,926 mother–infant pairs participated in the Hokkaido Study on Environment and Children’s Health, Japan, from 2002 to 2013. Medical reports were used to confirm HDP exposure, while weight, height, height z score, and weight z score were the outcomes. The prevalence of HDP in the study population was 1.7%. The birth height of male children born to HDP mothers was smaller as compared to those born to non-HDP mothers. When adjusted with covariates, the linear regressions showed significant changes in birth weight (β: −79.3; 95% confidence interval [CI]: −154.8, −3.8), birth height (−0.67; 95% CI: −1.07, −0.26), weight at seven years (1.21; 95% CI: 0.13, 2.29), and weight gain between four and seven years (1.12; 95% CI: 0.28, 1.96) of male children exposed to HDP. Differences were more significant in male children than female. Our study showed that despite low birth weight, male children exposed to HDP caught up with their growth and gained more weight by seven years of age compared with male children not exposed to HDP, whereas no such differences were observed in female children; however, this finding requires replication.

Abstract
INTRODUCTION Preeclampsia (PE) is a common pregnancy disorder with multisystem complications. The growing data suggest that circular RNAs (circRNAs) involve in the development of PE. This study proposed to investigate the function and potential mechanisms of circ_0001438 in PE. METHODS The expression of circ_0001438, miR-942 and NOD-like receptor pyrin domain-containing protein 3 (NLRP3) was measured by quantitative real-time polymerase chain reaction (qRT-PCR). The expression at the protein level of NLRP3, interleukin 1 beta (IL-1β), interleukin 10 (IL-10), B-cell lymphoma 2 (Bcl-2), Cleaved-caspase-3 (Cleaved-casp-3), N-cadherin and E-cadherin was detected by Western blot. Cell proliferation was assessed by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay and colony formation assay. Cell apoptosis was determined by flow cytometry assay. Cell migration and invasion were monitored by transwell assay. The target genes were obtained and verified by the online bioinformatics tool and dual-luciferase reporter assay. RESULTS The expression of circ_0001438 and NLRP3 was enhanced in PE placenta tissues. Circ_0001438 knockdown promoted cell proliferation, migration and invasion but inhibited apoptosis and inflammatory responses in HTR-8/Svneo cells, and these effects were reversed by the inhibition of miR-942, a target of circ_0001438. Moreover, NLRP3 was bounded by miR-942. The enrichment of miR-942 accelerated cell proliferation, migration and invasion but depleted apoptosis and inflammatory responses, while these impacts were partly abolished by NLRP3 overexpression. DISCUSSION Circ_0001438 sponged miR-942 to regulate the expression of NLRP3, and circ_0001438 aggravated the dysfunctions of human villous trophoblasts by mediating the miR-942/NLRP3 axis at least in part.

Abstract
We compared placental pathology, ultrasonographic findings, and obstetric outcomes, in gestations complicated by fetal growth restriction (FGR) with either a background of hypertensive disorder or heavy tobacco cigarette smoking. The medical records and placental pathology reports of pregnancies complicated with FGR (birthweight < 10th percentile) between December 2008 and May 2018 from a single tertiary center were reviewed. Placental pathology, ultrasound findings, and pregnancy outcomes were compared between hypertensive patients (HTN) and heavy smokers (SMO). We included 213 pregnancies: 129 (60.6%) in the SMO group and 84 (39.4%) in the HTN group. The HTN group was characterized by a higher BMI (p = 0.01), higher rates of Cesarean deliveries (p = 0.006), and a lower gestational age at delivery (35.6 ± 3.8 vs. 37.5 ± 2.9 weeks, p < 0.001). The HTN group had higher rates of placental weights < 10th percentile (p = 0.04) and maternal vascular malperfusion lesions (p < 0.001), while the SMO group had higher rates of inflammatory lesions (p = 0.04). On ultrasound, the HTN group had a higher head/abdomen circumference ratio (p < 0.001) and more abnormal Doppler studies (< 0.001). Neonates in the HTN group had lower birthweights (p < 0.001) and higher rates of NICU admissions (p = 0.002) and adverse neonatal outcome (p = 0.006). On multivariable analysis, gestational age at delivery (aOR = 0.65, 95%CI 0.55-0.87), hypertensive disorders (aOR = 1.8, 95%CI = 1.21-4.81), placental MVM lesions (aOR = 1.23, 95%CI = 1.08-5.02), and the combination of HTN+MVM (aOR = 2.63, 95%CI 1.78-7.30) were independently associated with adverse neonatal outcome. Hypertension and smoking may lead to FGR in different pathways as the two groups significantly differed in maternal characteristics, placental pathology, ultrasound findings, and neonatal outcomes. A hypertensive disorder probably represents a more hostile maternal environment than smoking and these pregnancies would probably benefit from closes monitoring.

Non-Criteria Antiphospholipid Antibodies: Risk Factors for Endothelial Dysfunction in Women with Pre-Eclampsia. Life (Basel) 2020; 10:E241. [PMID: 33066645 PMCID: PMC7650548 DOI: 10.3390/life10100241] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 10/11/2020] [Accepted: 10/12/2020] [Indexed: 11/16/2022] Open
Abstract
The association between unconventional antiphospholipid antibodies and pre-eclampsia in patients without thrombotic manifestations and its relationship with endothelial dysfunction after delivery has been studied poorly. We included 157 pregnant women, 122 of them having developed pre-eclampsia (56 non-severe and 66 severe). The determination of classical and unconventional, as well as pulse wave velocity and ankle-brachial index were performed at three months after delivery. The prevalence of unconventional antiphospholipid antibodies was 22.9% and 54.9% in patients included in control and pre-eclampsia groups, respectively (p = 0.001). The most frequent antiphospholipid antibody was IgM anti-phosphatidylserine/prothrombin in both cohorts. The presence of IgM anti-phosphatidylserine/prothrombin showed an association with the development of pre-eclampsia (OR = 5.4; CI 95% (2.0-14.9), p = 0.001) with an AUC of 0.744 (p < 0.001). Likewise, IgM anti-phosphatidylserine/prothrombin exhibited a positive linear correlation with pulse wave velocity values (rho = 0.830; p < 0.001) and an association with the presence of pulse wave velocity altered values (OR = 1.33; CI95% (1.10-1.59), p = 0.002). With regard to ankle braquial index values, the presence of IgM anti-phosphatidylserine/prothrombin displayed a weak negative correlation (rho = -0.466; p < 0.001) and an association with altered ankle braquial index values (OR = 1.08; CI 95% (1.04-1.13), p < 0.001). In patients who developed preeclampsia, the presence of IgM anti-phosphatidylserine/prothrombin could be associated with endothelial dysfunction, causing alteration of cardiovascular parameters.

Abstract
PURPOSE Previous microneurographic studies found that muscle sympathetic nerve activity (MSNA) increased in normotensive pregnant women and was even greater in women with gestational hypertension and preeclampsia during the third trimester. It is possible that sympathetic activation during the latter months of normal pregnancy helps return arterial pressure to non-pregnant levels. However, when the increase in sympathetic activity is excessive, hypertension ensues. The key question that must be addressed is whether sympathetic activation develops early during pregnancy and remains high throughout gestation, or whether this sympathetic overactivity only occurs at term, providing the substrate for preeclampsia and other pregnancy-associated cardiovascular complications. METHODS This was a literature review of autonomic neural control during pregnancy. RESULTS Recent work from our laboratory and other laboratories showed that in healthy women resting MSNA increased in early pregnancy, increased further in late pregnancy, and returned to the pre-pregnancy levels shortly after delivery. We found that women who exhibited excessive sympathetic activation during the first trimester, before any clinical signs and symptoms appeared, developed gestational hypertension at term. We also found that the level of corin, an atrial natriuretic peptide-converting enzyme, was increased in the maternal circulation, especially during late pregnancy, as a homeostatic response to elevated sympathetic activity. CONCLUSION These findings provide important insight into the neural mechanisms underlying hypertensive disorders during pregnancy. With this knowledge, early prevention or treatment targeted to the appropriate pathophysiology may be initiated, which may reduce maternal and fetal death or morbidity, as well as cardiovascular risks in women later in life.

Abstract
Recurrent or first preeclampsia in multiparae : a case-control study of singleton pregnancies in Reunion Island Phuong Lien Tran, Pierre-Yves Robillard, Coralie Dumont, Chloé Schweizer, Asma Omarjee, Glorianne Lazaro, Silvia Iacobelli, Malik Boukerrou OBJECTIVE: To compare multiparous women with a first occurrence of preeclampsia and those with recurrent preeclampsia in singleton pregnancies. STUDY DESIGN a 17.5-year (2001-2018) case-control study conducted in the University's maternity of South Reunion (Indian Ocean), comparing 125 patients with recurrent preeclampsia and 742 patients with a first episode of the disease (controls). Statistical analyses were performed with use of the Student t-test for comparison of continuous data and the Chi-square or Fisher exact test for comparison of categorical variables. RESULTS There was no difference between the two groups concerning socio-demographic characteristics, post-partum haemorrhage, perinatal mortality rates. Nevertheless, recurrent preeclamptic women had a higher risk to present with prior chronic hypertension (OR 2.05 [1.30-3.23], p = 0.002), and to experience an early onset preeclampsia (< 34 weeks) compared to controls (OR 1.69 [1.15-2.48], p = 0.007). Women with recurrent preeclampsia were more prone to have C-sections (OR 1.63 [1.06-2.51], p = 0.024) mainly because of maternal indications (89.2% vs 76.4%, p = 0.008). Newborns from recurrent preeclampsia were more likely to have very low birthweight < 1500 g (OR 1.79 [1.16-2.77], p = 0.001), while there was no significant difference for gestational ages (34.1 vs 34.7 weeks). CONCLUSION Recurrent multiparous preeclamptic women presented more severe maternal disease (with a higher rate of early onset preeclampsia). Persistent hypertension in women with a history of preeclampsia is a risk factor for developing recurrent preeclampsia, and these patients should be monitored more closely.

Abstract
Objective: To assess the secondary preventive effect of low-molecular-weight heparin (LMWH) on pregnant women with prior early-onset or severe preeclampsia (PE).Methods: A systematic literature search of several databases was conducted for randomized controlled trials comparing LMWH with either aspirin or no treatment in pregnant women at a high risk of placental-mediated pregnancy complications (PMPCs). Odds ratios and associated 95% confidence intervals (CI) and weighted mean differences and 95% CI were calculated.Results: Seven studies including 1035 patients were evaluated. These studies showed a risk reduction in composite PMPC outcome (relative risk (RR) 0.635 (95% CI: 0.436-0.925); p=.018), PE (RR 0.522 (95% CI: 0.334-0.815); p=.004), a small-for-gestational-age neonate (RR 0.622 (95% CI: 0.440-0.880); p=.007), and an increase in gestational length (SMD 0.312 (95% CI: 0.017-0.607); p=.038) and neonatal weight (SMD 0.428 (95% CI: 0.066-0.791); p=.020).Conclusions: LMWH has a secondary preventive effect on early or severe PE and improves neonatal outcomes. In the future, additional large multicenter studies will need to focus on high-risk PE groups by more accurate screening to obtain more information before clinical application.

Abstract
Preeclampsia is a disease of the mother, fetus, and placenta, and the gaps in our understanding of the complex interactions among their respective disease pathways preclude successful treatment and prevention. The placenta has a key role in the pathogenesis of the terminal pathway characterized by exaggerated maternal systemic inflammation, generalized endothelial damage, hypertension, and proteinuria. This sine qua non of preeclampsia may be triggered by distinct underlying mechanisms that occur at early stages of pregnancy and induce different phenotypes. To gain insights into these molecular pathways, we employed a systems biology approach and integrated different "omics," clinical, placental, and functional data from patients with distinct phenotypes of preeclampsia. First trimester maternal blood proteomics uncovered an altered abundance of proteins of the renin-angiotensin and immune systems, complement, and coagulation cascades in patients with term or preterm preeclampsia. Moreover, first trimester maternal blood from preterm preeclamptic patients in vitro dysregulated trophoblastic gene expression. Placental transcriptomics of women with preterm preeclampsia identified distinct gene modules associated with maternal or fetal disease. Placental "virtual" liquid biopsy showed that the dysregulation of these disease gene modules originates during the first trimester. In vitro experiments on hub transcription factors of these gene modules demonstrated that DNA hypermethylation in the regulatory region of ZNF554 leads to gene down-regulation and impaired trophoblast invasion, while BCL6 and ARNT2 up-regulation sensitizes the trophoblast to ischemia, hallmarks of preterm preeclampsia. In summary, our data suggest that there are distinct maternal and placental disease pathways, and their interaction influences the clinical presentation of preeclampsia. The activation of maternal disease pathways can be detected in all phenotypes of preeclampsia earlier and upstream of placental dysfunction, not only downstream as described before, and distinct placental disease pathways are superimposed on these maternal pathways. This is a paradigm shift, which, in agreement with epidemiological studies, warrants for the central pathologic role of preexisting maternal diseases or perturbed maternal-fetal-placental immune interactions in preeclampsia. The description of these novel pathways in the "molecular phase" of preeclampsia and the identification of their hub molecules may enable timely molecular characterization of patients with distinct preeclampsia phenotypes.

The prediction of late-onset preeclampsia: Results from a longitudinal proteomics study. PLoS One 2017; 12:e0181468.

Abstract
BACKGROUND Late-onset preeclampsia is the most prevalent phenotype of this syndrome; nevertheless, only a few biomarkers for its early diagnosis have been reported. We sought to correct this deficiency using a high through-put proteomic platform. METHODS A case-control longitudinal study was conducted, including 90 patients with normal pregnancies and 76 patients with late-onset preeclampsia (diagnosed at ≥34 weeks of gestation). Maternal plasma samples were collected throughout gestation (normal pregnancy: 2-6 samples per patient, median of 2; late-onset preeclampsia: 2-6, median of 5). The abundance of 1,125 proteins was measured using an aptamers-based proteomics technique. Protein abundance in normal pregnancies was modeled using linear mixed-effects models to estimate mean abundance as a function of gestational age. Data was then expressed as multiples of-the-mean (MoM) values in normal pregnancies. Multi-marker prediction models were built using data from one of five gestational age intervals (8-16, 16.1-22, 22.1-28, 28.1-32, 32.1-36 weeks of gestation). The predictive performance of the best combination of proteins was compared to placental growth factor (PIGF) using bootstrap. RESULTS 1) At 8-16 weeks of gestation, the best prediction model included only one protein, matrix metalloproteinase 7 (MMP-7), that had a sensitivity of 69% at a false positive rate (FPR) of 20% (AUC = 0.76); 2) at 16.1-22 weeks of gestation, MMP-7 was the single best predictor of late-onset preeclampsia with a sensitivity of 70% at a FPR of 20% (AUC = 0.82); 3) after 22 weeks of gestation, PlGF was the best predictor of late-onset preeclampsia, identifying 1/3 to 1/2 of the patients destined to develop this syndrome (FPR = 20%); 4) 36 proteins were associated with late-onset preeclampsia in at least one interval of gestation (after adjustment for covariates); 5) several biological processes, such as positive regulation of vascular endothelial growth factor receptor signaling pathway, were perturbed; and 6) from 22.1 weeks of gestation onward, the set of proteins most predictive of severe preeclampsia was different from the set most predictive of the mild form of this syndrome. CONCLUSIONS Elevated MMP-7 early in gestation (8-22 weeks) and low PlGF later in gestation (after 22 weeks) are the strongest predictors for the subsequent development of late-onset preeclampsia, suggesting that the optimal identification of patients at risk may involve a two-step diagnostic process.

Abstract
OBJECTIVE To evaluate whether daily enoxaparin, added to low-dose aspirin, started before 14 weeks of gestation reduces placenta-mediated complications in pregnant women with previous severe preeclampsia diagnosed before 34 weeks of gestation. METHODS In this open-label multicenter randomized trial, we enrolled consenting pregnant women with previous severe preeclampsia diagnosed before 34 weeks of gestation, gestational age at randomization of 7-13 weeks, singleton pregnancy, and no plan for anticoagulation. Eligible patients were randomly assigned to a one-to-one ratio to receive daily either 4,000 international units enoxaparin plus 100 mg aspirin or 100 mg aspirin alone. Randomization was done by a web-based randomization system. The primary composite outcome comprised maternal death, perinatal death, preeclampsia, small for gestational age (less than the 10th percentile), and placental abruption. A sample size of 232 women equally divided into two groups was needed to detect a significant reduction in primary outcome from 55% in the aspirin group to 36.7% in the enoxaparin-aspirin group (α: 0.05, β: 0.8, two-sided). RESULTS Between November 14, 2009, and February 21, 2015, 257 participants were enrolled. Baseline demographic and clinical factors were similar between groups. Eight women were excluded after randomization (six in the enoxaparin-aspirin group and two in the aspirin group), leaving 124 participants assigned to enoxaparin-aspirin and 125 to aspirin. Five participants were lost to follow-up (two in the enoxaparin-aspirin group and three in the aspirin group). There was no significant difference between the groups in the primary outcome: enoxaparin-aspirin 42 of 122 (34.4%) compared with aspirin alone 50 of 122 (41%) (relative risk 0.84, 95% confidence interval 0.61-1.16, P=.29). The occurrence of complications did not differ between the two groups. CONCLUSION Antepartum prophylactic enoxaparin does not significantly reduce placenta-mediated complications in women receiving low-dose aspirin for previous severe preeclampsia diagnosed before 34 weeks of gestation.

Am J Obstet Gynecol 2017; 216:527.e1-527.e9. [PMID: 28043842 DOI: 10.1016/j.ajog.2016.12.174] [Citation(s) in RCA: 90] [Impact Index Per Article: 12.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2016] [Revised: 12/16/2016] [Accepted: 12/27/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Preeclampsia is a prevalent and enigmatic disease, in part characterized by poor remodeling of the spiral arteries. However, preeclampsia does not always clinically present when remodeling has failed to occur. Hypotheses surrounding the "second hit" that is necessary for the clinical presentation of the disease focus on maternal inflammation and oxidative stress. Yet, the studies to date that have investigated these factors have used cross-sectional study designs or small study populations. OBJECTIVE In the present study, we sought to explore longitudinal trajectories, beginning early in gestation, of a panel of inflammation and oxidative stress markers in women who went on to have preeclamptic or normotensive pregnancies. STUDY DESIGN We examined 441 subjects from the ongoing LIFECODES prospective birth cohort, which included 50 mothers who experienced preeclampsia and 391 mothers with normotensive pregnancies. Participants provided urine and plasma samples at 4 time points during gestation (median, 10, 18, 26, and 35 weeks) that were analyzed for a panel of oxidative stress and inflammation markers. Oxidative stress biomarkers included 8-isoprostane and 8-hydroxydeoxyguanosine. Inflammation biomarkers included C-reactive protein, the cytokines interleukin-1β, -6, and -10, and tumor necrosis factor-α. We created Cox proportional hazard models to calculate hazard ratios based on time of preeclampsia diagnosis in association with biomarker concentrations at each of the 4 study visits. RESULTS In adjusted models, hazard ratios of preeclampsia were significantly (P<.01) elevated in association with all inflammation biomarkers that were measured at visit 2 (median, 18 weeks; hazard ratios, 1.31-1.83, in association with an interquartile range increase in biomarker). Hazard ratios at this time point were the most elevated for C-reactive protein, for interleukin-1β, -6, and -10, and for the oxidative stress biomarker 8-isoprostane (hazard ratio, 1.68; 95% confidence interval, 1.14-2.48) compared to other time points. Hazard ratios for tumor necrosis factor-α were consistently elevated at all 4 of the study visits (hazard ratios, 1.49-1.63; P<.01). In sensitivity analyses, we observed that these associations were attenuated within groups typically at higher risk of experiencing preeclampsia, which include African American mothers, mothers with higher body mass index at the beginning of gestation, and pregnancies that ended preterm. CONCLUSIONS This study provides the most robust data to date on repeated measures of inflammation and oxidative stress in preeclamptic compared with normotensive pregnancies. Within these groups, inflammation and oxidative stress biomarkers show different patterns across gestation, beginning as early as 10 weeks. The start of the second trimester appears to be a particularly important time point for the measurement of these biomarkers. Although biomarkers alone do not appear to be useful in the prediction of preeclampsia, these data are useful in understanding the maternal inflammatory profile in pregnancy before the development of the disease and may be used to further develop an understanding of potentially preventative measures.

Abstract
BACKGROUND Preeclampsia and small-for-gestational-age pregnancy are major causes of maternal and perinatal morbidity and mortality. Women with a previous pregnancy affected by these conditions are at an increased risk of recurrence in a future pregnancy. Past trials evaluating the effect of low-molecular-weight heparin for the prevention of recurrence of preeclampsia and small-for-gestational-age pregnancy have shown conflicting results with high levels of heterogeneity displayed when trials were compared. OBJECTIVE We sought to assess the effectiveness of enoxaparin in addition to high-risk care for the prevention of preeclampsia and small-for-gestational-age pregnancy in women with a history of these conditions. STUDY DESIGN This was an open-label randomized controlled trial in 5 tertiary care centers in 3 countries. Women with a viable singleton pregnancy were invited to participate between >6+0 and <16+0 weeks if deemed to be at high risk of preeclampsia and/or small for gestational age based on their obstetric history. Eligible participants were randomly assigned in a 1-to-1 ratio to standard high-risk care or standard high-risk care plus enoxaparin 40 mg (4000 IU) by subcutaneous injection daily from recruitment until 36+0 weeks or delivery, whichever occurred sooner. Standard high-risk care was defined as care coordinated by a high-risk antenatal clinic service, aspirin 100 mg daily until 36+0 weeks, and-for women with prior preeclampsia-calcium 1000-1500 mg daily until 36+0 weeks. In a subgroup of participants serum samples were taken at recruitment and at 20 and 30 weeks' gestation and later analyzed for soluble fms-like tyrosine kinase-1, soluble endoglin, endothelin-1, placental growth factor, and soluble vascular cell adhesion molecule 1. The primary outcome was a composite of preeclampsia and/or small-for-gestational-age <5th customized birthweight percentile. All data were analyzed on an intention-to-treat basis. The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12609000699268). RESULTS Between July 26, 2010, and Oct. 28, 2015, a total of 156 participants were enrolled and included in the analysis. In all, 149 participants were included in the outcome analysis (72 receiving standard high-risk care plus enoxaparin and 77 receiving standard high-risk care only). Seven women who miscarried <16 weeks' gestation were excluded. The majority of participants (151/156, 97%) received aspirin. The addition of enoxaparin had no effect on the rate of preeclampsia and/or small-for-gestational-age <5th customized birthweight percentile: enoxaparin 18/72 (25%) vs no enoxaparin 17/77 (22.1%) (odds ratio, 1.19; 95% confidence interval, 0.53-2.64). There was also no difference in any of the secondary outcome measures. Levels of soluble fms-like tyrosine kinase-1 and soluble endoglin increased among those who developed preeclampsia, but there was no difference in levels of these antiangiogenic factors (nor any of the other serum analytes measured) among those treated with enoxaparin compared to those receiving standard high-risk care only. CONCLUSION The use of enoxaparin in addition to standard high-risk care does not reduce the risk of recurrence of preeclampsia and small-for-gestational-age infants in a subsequent pregnancy.

Abstract
BACKGROUND A preponderance of male fetuses in pregnancies complicated by pre-eclampsia was described over 40 years ago. Since then, however, there has been conflicting evidence in the literature, with some studies supporting a male preponderance, some demonstrating no relationship with fetal sex, and others reporting increased risk in pregnancies bearing females. OBJECTIVES In this context, we sought to conduct a systematic review and meta-analysis to objectively evaluate the relationship between fetal sex and maternal risk of pre-eclampsia/eclampsia. SEARCH STRATEGY Studies from January 1950 to April 2015 were identified from PUBMED and EMBASE. SELECTION CRITERIA This systematic review and meta-analysis evaluated 22 articles reporting data on fetal sex and prevalence of pre-eclampsia/eclampsia. DATA COLLECTION AND ANALYSIS Data were extracted by two independent reviewers. Pooled estimates of the relative risk (RR) were calculated by random-effects model. MAIN RESULTS Male fetus was considered the exposure and prevalence of maternal pre-eclampsia/eclampsia was the outcome of interest. We identified 534 studies through electronic searches and three studies through manual searches. Twenty-two studies fulfilled the inclusion criteria, yielding data on 3 163 735 women. Pooled analyses of these studies showed no association between male fetal sex and maternal risk of pre-eclampsia/eclampsia (RR 1.01; 95% confidence interval, 95% CI 0.97-1.05); however, a subgroup analysis including only studies that evaluated the non-Asian population (n = 2 931 771 women) demonstrated that male fetal sex was associated with increased maternal risk of pre-eclampsia/eclampsia (RR 1.05; 95% CI 1.03-1.06; I2 = 10%; P = 0.33). CONCLUSION Male fetal sex is associated with maternal risk of pre-eclampsia/eclampsia in the non-Asian population. TWEETABLE ABSTRACT Fetal sex is associated with maternal risk of pre-eclampsia/eclampsia in the non-Asian population.

Enoxaparin for the prevention of preeclampsia and intrauterine growth restriction in women with a prior history - an open-label randomised trial (the EPPI trial): study protocol. BMC Pregnancy Childbirth 2016; 16:367. [PMID: 27876004 PMCID: PMC5120461 DOI: 10.1186/s12884-016-1162-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2016] [Accepted: 11/15/2016] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Preeclampsia and intrauterine fetal growth restriction (IUGR) are two of the most common causes of maternal and perinatal morbidity and mortality. Current methods of predicting those at most risk of these conditions remain relatively poor, and in clinical practice past obstetric history remains the most commonly used tool. Aspirin and, in women at risk of preeclampsia only, calcium have been demonstrated to have a modest effect on risk reduction. Several observational studies and randomised trials suggest that low molecular weight heparin (LMWH) therapy may confer some benefit. METHODS/DESIGN This is a multicentre open label randomised controlled trial to determine the effect of the LMWH, enoxaparin, on the prevention of recurrence of preeclampsia and/or IUGR in women at high risk due to their past obstetric history in addition to standard high risk care for all participants. INCLUSION CRITERIA A singleton pregnancy >6+0 and <16+0 weeks gestation with most recent prior pregnancy with duration >12 weeks having; (1) preeclampsia delivered <36+0 weeks, (2) Small for gestational age (SGA) infant <10th customised birthweight centile delivered <36+0 weeks or, (3) SGA infant ≤3rd customised birthweight centile delivered at any gestation. Randomisation is stratified for maternal thrombophilia status and women are randomly assigned to 'standard high risk care' or 'standard high risk care' plus enoxaparin 40 mg from recruitment until 36+0 weeks or delivery, whichever occurs sooner. Standard high risk care includes the use of aspirin 100 mg daily and calcium 1000-1500 mg daily (unless only had previous SGA with no preeclampsia). The primary outcome is preeclampsia and/or SGA <5th customised birthweight centile. Analysis will be by intention to treat. DISCUSSION The EPPI trial has more focussed and clinically relevant inclusion criteria than other randomised trials with a more restricted composite primary outcome. The inclusion of standard use of aspirin (and calcium) for all participants will help to ensure that any differences observed in outcome are likely to be related to enoxaparin use. These data will make a significant contribution to future meta-analyses and systematic reviews on the use of LMWH for the prevention of placental mediated conditions.

Abstract
OBJECTIVE We aimed to study the role of placental pathology in the prediction of preeclampsia (PE) recurrence. METHODS The medical records and pathological placental reports of all women diagnosed with PE, during 2008-2015, were reviewed. The study population was divided according to the outcome of their subsequent pregnancy: those who did (recurrence group) or did not (no-recurrence group) develop recurrent PE. Data regarding maternal characteristics and placental maternal/fetal vascular malperfusion lesions, of the initial pregnancies, were compared. Two prediction models were generated for PE recurrence. RESULTS Compared to the no-recurrence group (n = 130), the recurrence group (n = 96) was characterized by lower gestational age (p < 0.001), longer inter-pregnancy interval (p = 0.012), and higher rate of severe features (p < 0.001). By logistic regression analysis composite maternal (aOR = 3.05, 95%CI 1.39-6.71, p = 0.005), fetal (aOR = 9.31, 95%CI 3.9-22.1, p < 0.001), and concurrent maternal + fetal (aOR = 13.94, 95%CI 5.08-38.21, p < 0.001), vascular malperfusion lesions were found to be independently associated with recurrence. A clinical prediction model accounted for 20.8% of PE recurrence (R2 = 0.208, AUC = 0.732), while a clinical-pathological model accounted for 34.2% of recurrence (R2 = 0.342, AUC = 0.80). CONCLUSION Placental maternal and fetal vascular malperfusion lesions are independently associated with increased risk for PE recurrence. A clinical-pathological prediction model for recurrence of PE is superior to a prediction model based merely on clinical factors. © 2016 John Wiley & Sons, Ltd.

Abstract
The U.S. infant mortality rate (IMR) increased from 6.8 infant deaths per 1,000 live births in 2001 to 7.0 in 2002, the first increase in more than 40 years. From 2001 to 2002, IMR increased for very low birthweight infants as well as for preterm and very preterm infants. Although IMR for very low birthweight infants increased, most of the increase in IMR from 2001 to 2002 was due to a change in the distribution of births by birthweight and, more specifically, to an increase in infants born weighing less than 750 grams. The majority of infants born at less than 750 grams die within the first year of life; thus, these births contribute disproportionately to overall IMR. Increases in births at less than 750 grams occurred for non-Hispanic white, non-Hispanic black, and Hispanic women. Most of the increase occurred among mothers 20 to 34 years of age. Although multiple births contributed disproportionately, most of the increase in births at less than 750 grams occurred among singletons. Three hypotheses were evaluated to assess their possible impact on the increase in less than 750-gram births: possible changes in (1) the reporting of births or fetal deaths, (2) the risk profile of births, and (3) medical management of pregnancy. Although each of these factors may have contributed to the increase, the relative effects of these and other factors remain unclear. More detailed studies are needed to further explain the 2001–2002 infant mortality increase.

Abstract
Preeclampsia is a syndrome occurring only in pregnancy characterized by systemic maternal inflammation and associated with the presence of the placenta. How these 2 aspects of the disease are linked has been the subject of numerous theories and ideas. Recently, there has been increasing interest in DNA shed from the placenta into the maternal circulation as a potential agent initiating the inflammatory response. This review will discuss the current evidence and future directions for placental DNA as the linking factor in preeclampsia in the context of other hypotheses.

Abstract
Background Complications are common in twin pregnancies and induction of labour is often indicated. Most methods for induction are used but data on risks related to induction methods are sparse. The aim of this study was to investigate the association between induction of labour and caesarean delivery in twin pregnancies, and to assess the influence of induction method. Methods Cohort study of twin pregnancies ≥ 34 weeks, planned for vaginal delivery, from two University Hospitals in Sweden. Data were collected from medical records during the periods 1994 (Örebro) and 2004 (Uppsala) to 2013. During the study period there were 78,180 live born births and 1,282 were twin births. Women with previous caesarean section were excluded. Induction methods were categorized into amniotomy, oxytocin and cervical ripening (intra cervical Foley catheter or prostaglandin). Adjusted odds ratios (AOR) with 95 % confidence interval (CI) for caesarean section were calculated by logistic regression and were adjusted for parity, maternal age, gestational length, complications to the pregnancy, infant birth weight and year of birth. Spontaneous labour onsets were used as the reference group. The main outcome measure was caesarean section. Results In 462 twin pregnancies, 220 (48 %) had induction of labour and 242 (52 %) a spontaneous labour onset. Amniotomy was performed in 149 (68 %) of these inductions, oxytocin was administered in 11 (5 %) and cervical ripening was used in 60 (27 %). The rate of caesarean sections was 21 % in induced and 12 % in spontaneous labours (p 0.01). The absolute risk of caesarean section following induction was: 15 % with amniotomy; 36 % with oxytocin and 37 % with Foley/prostaglandin. Induction of labour increased the risk of caesarean section by 90 % compared with spontaneous labour onset (AOR 1.9, 95 % CI 1.1-3.5) and, when cervical ripening was used, the risk increased more than two fold (AOR 2.5, 95 % CI 1.2-5.3). Conclusion Induction of labour in twin pregnancies increases the risk of caesarean section compared with spontaneous labour onset, especially if Foley catheter or prostaglandins are required. However, approximately 80 % of induced labours are delivered vaginally.

Abstract
INTRODUCTION Lifestyle during pregnancy has long-term effects on health of mother and child. Having previous illness or unexpected maternal or fetal conditions such as preeclampsia can complicate pregnancy and interfere with health-promoting behaviors and cause stress might interfere with health-promoting behaviors. This study was carried out to examine the relationship between health-promoting lifestyles and perceived stress in women with preeclampsia. METHODS This study is a descriptive correlation design that was conducted on 182 pregnant women with preeclampsia attending in the high risk clinics of Al-Zahra and Talegani hospitals in Tabriz 2014. Data gathering tools were three: demographics, health-promoting lifestyle (HPLP-II), and perceived stress questionnaires. SPSS Ver. 13 was used for data analysis. RESULTS The mean (SD) of health promoting lifestyle among pregnant women with preeclampsia was 2.4 (0.4). Among the dimensions of health promoting life style, the highest mean score was for sub domain of nutrition, i.e. 2.8 (0.5), and the lowest score was achieved by the sub-domains of physical activity, i.e. 1.5 (0.5).The mean (SD) score of perceived stress was 27.3 (7.1). There was reverse relationship between perceived stress and health -promoting behaviors. CONCLUSION Based upon the results, health promoting behaviors were decreased by increment of perceived stress. Therefore, midwives can help women with preeclampsia by promoting health behaviors to reduce their stress and increase health-promoting behaviors.

Abstract
OBJECTIVE To establish the spectrum of diseases in the obstetric patient that involves an increase in the length of stay in the Recovery Unit of a specialist Maternity Hospital. To analyse the severity of these conditions as regards the means required for their resolu-tion, as well as to identify the factors that influence on post-operative morbidity in the obstetric patient. MATERIAL AND METHODS All the case histories of all the patients admitted to the Maternity Hospital Recovery Unit during the year 2008 were reviewed. Those who required a lon-ger stay than usual were selected, which included, those with more than 6hours after a caesarean, and all admissions made during pregnancy, or after dilation and curettage or partum. RESULTS Out of a total of 10419 births delivered in 2008, 3000 obstetric patients were ad-mitted to the Maternity Hospital Recovery Unit, of which 285 (9.5%) required critical care. The most frequent cause of increased length of stay was obstetric haemorrhage, followed by hypertensive states of pregnancy. No patients died in this Unit in the year 2008. CONCLUSIONS The number of patients who had an increased length of stay in the Mater-nity Hospital Recovery Unit is similar to the percentage of patients who are admitted to Intensive Care Units in countries such as Canada or the United Kingdom, but our Unit had a lower death rate in the year evaluated. The main causes are obstetric haemorrhage and hypertensive states of pregnancy, thus patients with risk factors for developing these complications must be observed closely and monitored.

Abstract
OBJECTIVE To examine fetal malformations in mother-infant pairs with and without pregnancy-related hypertension. METHODS This was an observational, population-based study of women delivering a singleton at our hospital. Specific fetal malformations identified in women with gestational hypertension or preeclampsia were compared to those without pregnancy-related hypertension. Women with chronic hypertension, superimposed preeclampsia on chronic hypertension and pregestational diabetes were excluded. RESULTS Between March 2002 and December 2012, a total of 151 997 women delivered, and 10 492 (7%) had preeclampsia, 4282 (3%) had gestational hypertension and 137,223 (90%) were referent normotensive controls. Women with preeclampsia were significantly more likely to deliver infants with malformations when compared to normotensive controls (2.5% versus 1.6%, p < 0.001), whereas women with gestational hypertension were not (1.9% versus 1.6%, p = 0.16). The overall risk for fetal malformation associated with preeclampsia remained significant following logistic regression for age, race, parity and maternal body-habitus (adjusted OR 1.5; 95% CI: 1.3-1.7). Only single-organ system malformations - microcephaly and hypospadias - remained associated with preeclampsia (p < 0.001), and fetal growth restriction was a co-factor for both. CONCLUSIONS Preeclampsia was associated with increased rates of fetal malformations when compared to normotensive women - specifically microcephaly and hypospadias. These associations appear predominantly as a consequence of impaired fetal growth.

BACKGROUND Placenta-mediated pregnancy complications include pre-eclampsia, late pregnancy loss, placental abruption, and the small-for-gestational age newborn. They are leading causes of maternal, fetal, and neonatal morbidity and mortality in developed nations. Women who have experienced these complications are at an elevated risk of recurrence in subsequent pregnancies. However, despite decades of research no effective strategies to prevent recurrence have been identified, until recently. We completed a pooled summary-based meta-analysis that strongly suggests that low-molecular-weight heparin reduces the risk of recurrent placenta-mediated complications. The proposed individual patient data meta-analysis builds on this successful collaboration. The project is called AFFIRM, An individual patient data meta-analysis oF low-molecular-weight heparin For prevention of placenta-medIated pRegnancy coMplications. METHODS/DESIGN We conducted a systematic review to identify randomized controlled trials with a low-molecular-weight heparin intervention for the prevention of recurrent placenta-mediated pregnancy complications. Investigators and statisticians representing eight trials met to discuss the outcomes and analysis plan for an individual patient data meta-analysis. An additional trial has since been added for a total of nine eligible trials. The primary analyses from the original trials will be replicated for quality assurance prior to recoding the data from each trial and combining it into a common dataset for analysis. Using the anonymized combined data we will conduct logistic regression and subgroup analyses aimed at identifying which women with previous pregnancy complications benefit most from treatment with low-molecular-weight heparin during pregnancy. DISCUSSION The goal of the proposed individual patient data meta-analysis is a thorough estimation of treatment effects in patients with prior individual placenta-mediated pregnancy complications and exploration of which complications are specifically prevented by low-molecular-weight heparin.

Abstract
OBJECTIVES To assess the recurrence risk of term hypertensive disease of pregnancy and to determine which potential risk factors are predictive of recurrence. STUDY DESIGN We performed a retrospective cohort study in two secondary and one tertiary care hospitals in the Netherlands. We identified women with a hypertensive disorder in the index pregnancy and delivery after 37weeks of gestation between January 2000 and December 2002. Data were extracted from medical files and women were approached for additional information on subsequent pregnancies. Adverse outcome was defined as recurrence of a hypertensive disorder in the next subsequent pregnancy. MAIN OUTCOME MEASURES The absolute risk of recurrence and a prediction model containing demographic and clinical factors predictive of recurrence. RESULTS We identified 638 women for potential inclusion, of whom 503 could be contacted. Of these women, 312 (62%) had a subsequent pregnancy. Hypertensive disorders recurred in 120 (38%, 95% CI 33-44) women, of whom 15 (5%, 95% CI 3-7) delivered preterm. Women undergoing recurrence were more at risk to develop chronic hypertension after pregnancy (35% versus 16%, OR 2.8, 95% CI 1.5-5.3). Body mass index, non-White European origin, chronic hypertension, maximum diastolic blood pressure, no use of anticonvulsive medication and interpregnancy interval were predictors for recurrence. CONCLUSIONS Women with hypertensive disorders and term delivery have a substantial chance of recurrence, but a small risk of preterm delivery. A number of predictors for recurrence could be identified and women with a recurrence more often developed chronic hypertension.

Abstract
BACKGROUND Case control studies suggest that genetic thrombophilias increase the risk of placenta-mediated pregnancy complications (pregnancy loss, small for gestational age (SGA), preeclampsia and/or placental abruption). Cohort studies have not supported this association but were underpowered to detect small effects. OBJECTIVE To determine if factor V Leiden (FVL) or the prothrombin gene mutation (PGM) were associated with placenta-mediated pregnancy complications. PATIENTS/METHODS A prospective cohort of unselected, consenting pregnant women at three Canadian tertiary care hospitals had blood drawn in the early second trimester and were genotyped for FVL and PGM after delivery. The main outcome measure was a composite of pregnancy loss, SGA < 10th percentile, preeclampsia or placental abruption. RESULTS Complete primary outcome and genetic data were available for 7343 women. Most were Caucasian (77.7%, n = 5707), mean age was 30.4 (± 5.1) years, and half were nulliparous. There were 507 (6.9%) women with FVL and/or PGM; 11.64% had a placenta-mediated pregnancy complication. Of the remaining 6836 women, 11.23% experienced a complication. FVL and/or PGM was associated with a relative risk of 1.04 (95% CI, 0.81-1.33) for the composite outcome, with similar results after adjustment for important covariates. CONCLUSIONS Carriers of FVL or PGM are not at significantly increased risk of these pregnancy complications.

Abstract
Two women suffering from primary hyperparathyroidism in pregnancy are presented. Patient 1 with a history of four miscarriages, an ectopic pregnancy and a sixth pregnancy complicated by severe early onset preeclampsia. She was found to have high serum Ca(2+) levels after delivery and parathyroid adenoma was diagnosed by ultrasound. A right inferior parathyroidectomy was performed. Patient 2 with a history of high serum Ca(2+) and generalised symptoms of hypercalcaemia. Ultrasound did not reveal adenoma but an elective neck exploration was performed in light of the abnormal blood results. The right inferior parathyroid gland was excised and histology confirmed the presence of adenoma. These cases help highlight the different ways in which primary hyperparathyroidism can present and the barriers to diagnosis in pregnancy. Various potential complications (including miscarriage and preeclampsia) are explored and the appropriateness of surgical treatment during pregnancy is emphasised.

Abstract
INTRODUCTION Pre-eclampsia, which is more prevalent in resource-limited settings, contributes significantly to maternal, fetal and neonatal morbidity and mortality. However, the factors associated with these adverse outcomes are poorly understood in low resource settings. In this paper we examine the risk factors for adverse neonatal outcomes among women with pre-eclampsia at Mulago Hospital in Kampala, Uganda. METHODS Pre-eclampsia, which is more prevalent in resource-limited settings, contributes significantly to maternal, fetal and neonatal morbidity and mortality. However, the factors associated with these adverse outcomes are poorly understood in low resource settings. In this paper we examine the risk factors for adverse neonatal outcomes among women with pre-eclampsia at Mulago Hospital in Kampala, Uganda. RESULTS Predictors of adverse neonatal outcomes were: preterm delivery (OR 5.97, 95% CI: 2.97-12.7) and severe pre-eclampsia (OR 5.17, 95% CI: 2.36-11.3). CONCLUSION Predictors of adverse neonatal outcomes among women with pre-eclampsia were preterm delivery and severe pre-eclampsia. Health workers need to identify women at risk, offer them counseling and, refer them if necessary to a hospital where they can be managed successfully. This may in turn reduce the neonatal morbidity and mortality associated with pre-eclampsia.

Abstract
A 35-year-old woman with recurrent severe placenta-mediated pregnancy complications in her 2 pregnancies asks: Will low-molecular-weight heparin help prevent recurrent placenta-mediated pregnancy complications in my next pregnancy? We performed a meta-analysis of randomized controlled trials (RCTs) comparing low-molecular-weight heparin (LMWH) vs no LMWH for the prevention of recurrent placenta-mediated pregnancy complications. We identified six RCTs that included a total of 848 pregnant women with prior placenta-mediated pregnancy complications. The primary outcome was a composite of pre-eclampsia (PE), birth of a small-for-gestational-age (SGA) newborn (<10th percentile), placental abruption, or pregnancy loss >20 weeks. Overall, 67 (18.7%) of 358 of women being given prophylactic LMWH had recurrent severe placenta-mediated pregnancy complications compared with 127 (42.9%) of 296 women with no LMWH (relative risk reduction, 0.52; 95% CI, 0.32 to 0.86; P = .01; I(2), 69%, indicating moderate heterogeneity). We identified similar relative risk reductions with LMWH for individual outcomes, including any PE, severe PE, SGA <10th percentile, SGA <5th percentile, preterm delivery <37 weeks, and preterm delivery <34 weeks with minimal heterogeneity. LMWH may be a promising therapy for recurrent, especially severe, placenta-mediated pregnancy complications, but further research is required.
