Objective: The aim of this study was to investigate whether midtrimester isolated short femur length is associated with pregnancy complications. Study Design: Retrospective analysis of pregnancies with a midtrimester femur length <5th percentile for gestational age compared to controls with a femur length ≥5th percentile. Outcome measures included hypertensive disorders, being small for gestational age, oligohydramnios and preterm delivery. Results: 2,105 women were eligible for this study, 85 (3.45%) of whom were in the study group and 2,020 were controls. Birth weight <10th percentile for gestational age (OR 4.4, 95% CI 2.5-7.8), birth weight <3rd percentile for gestational age (OR 31.0, 95% CI 13.3-72.3) and severe preeclampsia (OR 6.3, 95% CI 1.4-28.6) were significantly associated with midtrimester isolated short femur length. Conclusions: Midtrimester isolated short femur length is associated with higher rates of being small for gestational age and preeclampsia.

Abstract Objective To determine the association between total gestational weight gain and perinatal outcomes. Study Design Data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be (NuMoM2b) study were used. Total gestational weight gain was categorized as inadequate, adequate, or excessive based on the 2009 Institute of Medicine guidelines. Outcomes examined included hypertensive disorders of pregnancy, mode of delivery, shoulder dystocia, large for gestational age or small for-gestational age birth weight, and neonatal intensive care unit admission. Results Among 8,628 women, 1,666 (19.3%) had inadequate, 2,945 (34.1%) had adequate, and 4,017 (46.6%) had excessive gestational weight gain. Excessive gestational weight gain was associated with higher odds of hypertensive disorders (adjusted odds ratio [aOR] = 2.05, 95% confidence interval [CI]: 1.78–2.36) Cesarean delivery (aOR = 1.24, 95% CI: 1.09–1.41), and large for gestational age birth weight (aOR = 1.49, 95% CI: 1.23–1.80), but lower odds of small for gestational age birth weight (aOR = 0.59, 95% CI: 0.50–0.71). Conversely, inadequate gestational weight gain was associated with lower odds of hypertensive disorders (aOR = 0.75, 95% CI: 0.62–0.92), Cesarean delivery (aOR = 0.77, 95% CI: 0.65–0.92), and a large for gestational age birth weight (aOR = 0.72, 95% CI: 0.55–0.94), but higher odds of having a small for gestational age birth weight (aOR = 1.64, 95% CI: 1.37–1.96). Conclusion Both excessive and inadequate gestational weight gain are associated with adverse maternal and neonatal outcomes.

Abstract Objective To test the hypothesis that high fetal fraction (FF) on first trimester cell-free deoxyribonucleic acid (cfDNA) aneuploidy screening is associated with adverse perinatal outcomes. Study Design This is a single-institution retrospective cohort study of women who underwent cfDNA screening at <14 weeks' gestation and delivered a singleton infant between July 2016 and June 2018. Women with abnormal results were excluded. Women with high FF (≥95th percentile) were compared with women with normal FF (5th–95th percentiles). Outcomes investigated were preterm birth, small for gestational age, and hypertensive disorders of pregnancy. Results A total of 2,033 women met inclusion criteria. The mean FF was 10.0%, and FF >16.5% was considered high (n = 102). Women with high FF had a greater chance of delivering a small for gestational age infant <fifth percentile, with an adjusted odds ratio of 2.4 (95% confidence interval: 1.1–4.8, p = 0.039). There was no significant association between high FF and either preterm birth or hypertensive disorders of pregnancy. Conclusion Women with a high FF in the first trimester are at increased risk of delivering a small for gestational age infant <fifth percentile. Further investigation into the clinical implications of a high FF is warranted.

Abstract Background Stillbirth remains a major concern across the globe and in some high-resource countries, such as the UK; efforts to reduce the rate have achieved only modest reductions. One third of stillborn babies are small for gestational age (SGA), and these pregnancies are also at risk of neonatal adverse outcomes and lifelong health problems, especially when delivered preterm. Current UK clinical guidance advocates regular monitoring and early term delivery of the SGA fetus; however, the most appropriate regimen for surveillance of these babies remains unclear and often leads to increased intervention for a large number of these women. This pilot trial will determine the feasibility of a large-scale trial refining the risk of adverse pregnancy outcome in SGA pregnancies using biomarkers of placental function sFlt-1/PlGF, identifying and intervening in only those deemed at highest risk of stillbirth. Methods PLANES is a randomised controlled feasibility study of women with an SGA fetus that will be conducted at two tertiary care hospitals in the UK. Once identified on ultrasound, women will be randomised into two groups in a 3:1 ratio in favour of sFlt-1/PlGF ratio led management vs standard care. Women with an SGA fetus and a normal sFlt-1/PlGF ratio will have a repeat ultrasound and sFlt-1/PlGF ratio every 2 weeks with planned birth delayed until 40 weeks. In those women with an SGA fetus and an abnormal sFlt-1/PlGF ratio, we will offer birth from 37 weeks or sooner if there are other concerning features on ultrasound. Women assigned to standard care will have an sFlt-1/PlGF ratio taken, but the results will be concealed from the clinical team, and the woman’s pregnancy will be managed as per the local NHS hospital policy. This integrated mixed method study will also involve a health economic analysis and a perspective work package exploring trial feasibility through interviews and questionnaires with participants, their partners, and clinicians. Discussion Our aim is to determine feasibility through the assessment of our ability to recruit and retain participants to the study. Results from this pilot study will inform the design of a future large randomised controlled trial that will be adequately powered for adverse pregnancy outcome. Such a study would provide the evidence needed to guide future management of the SGA fetus. Trial registration ISRCTN58254381. Registered on 4 July 2019

Singleton Pregnancies

Objectives To prospectively measure the distance from the placental cord insertion (PCI) site to the placental margin using digital imaging and to examine the association between abnormal PCI and adverse pregnancy outcomes in singleton pregnancies. Study Design This prospective cohort study examined 1,005 placentas from consecutively delivered singleton pregnancies in a tertiary center. Standardized images of each placenta were taken and digital measurement was performed using ImageJ software. Results The rates of velamentous (insertion into the membrane) and marginal (<2 cm from placental margin) cord insertions in a total of 1,005 singleton pregnancies were 3.6% (n  =  36; 95% confidence interval [CI]  =  2.5–4.9%) and 6.4% (n  =  64; 95% CI  =  4.9–8.1%), respectively. Abnormal PCI was found to be more common among smokers compared with non-smokers (22.7 vs. 14.8%, p = 0.04). Abnormal PCI was found to be significantly associated with small for gestational age (adjusted odds ratio [OR]: 1.73; 95% CI: 1.01–2.97, p = 0.047) and low birth weight (adjusted OR: 3.87; 95% CI: 1.72–8.71, p = 0.001). Conclusion Digital imaging analysis using ImageJ software mapped the surface of the placenta and provided objective measurement of PCI site. In this large prospective cohort, abnormal PCIs were significantly associated with an increased risk of small for gestational age and low birth weight.

Background:The role of complement in the antiphospholipid (aPL) related pathology has been widely studied in animal models. Antiphospholipid antibodies can induce fetal loss in experimental animals but mice deficient in specific complement components (C4, C3, C5) appear somehow protected. In addition, in pregnant mice injected with aPL, antibody deposition has been found at decidual level causing focal necrosis, apoptosis and neutrophil infiltrates and supporting aPL pathogenetic potential. On the other hand, human studies did find hypocomplementemia associated to pregnancy complications in patients with obstetric antiphospholipid syndrome (APS). These results, however, are not unanimously confirmed and, in addition, some studies only show increased levels of complement activation products (i.e. Bb) and not decreased levels of C3 and/or C4. A recently study focusing on complement level in early pregnancy and before pregnancy showed a significant correlation with pregnancy complications and loss in a large cohort of primary APS.Objectives:To investigate if the simple detection of low C3 and/or C4 could be considered a risk factor for adverse pregnancy outcome in APS and aPL carriers pregnancies.Methods:We performed a multicentric study including patients from 10 Italian and 1 Russian Centers. Data on pregnancies in women with primary APS (n=434) and asymptomatic carriers with persistently positive aPL but not fulfilling clinical criteria for APS (n=218) were retrospectively collected. Serum C3 and C4 levels were evaluated by nephelometry; hypocomplementemia was defined by local laboratory reference values. Statistical analysis was performed using GraphPad.Results:Preconceptional complement levels and gestational outcome were available for 107 (25%) pregnancies in APS out of 434 and for 196 (90%) pregnancies in aPL carriers women out of 218. In pregnancies with low preconceptional C3 and/or C4, a significantly higher prevalence of pregnancy losses was observed (p=0.019). A subgroup analysis focusing on triple aPL positive patients was also performed. Preconceptional low C3 and/or C4 levels were found to be associated with an increased rate of pregnancy loss (p = 0.027) in this subgroup also. Otherwise, adverse pregnancy outcomes in single or double aPL positive women were not related to preconception complement levels (p = 0.44) (Table 1). Of note, all the pregnancy losses in the triple positive group occurred in patients treated with low dose aspirin and low molecular weight heparin from the time of positive pregnancy test.Conclusion:Our findings confirm that decreased complement levels before pregnancy are associated with increased risk of adverse outcome. This has been seen only in in women with triple aPL positivity, indeed single or double positivity does not show this trend. Complement levels are cheap and easy to be measured therefore they could represent a useful aid to identify patients at increased risk of pregnancy loss. test positivity.References:[1]De Carolis S, et al.
