Abstract
BACKGROUND Research on the definition of fetal growth restriction (FGR) has focused on predicting adverse perinatal outcomes. A significant limitation of this approach is that the individual outcomes of interest could be related to the condition and the treatment. Evaluation of outcomes that reflect the pathophysiology of FGR may overcome this limitation. OBJECTIVE To compare the diagnostic performance of the FGR definitions established by the International Society for Ultrasound in Obstetrics and Gynecology (ISUOG) and the Society for Maternal-Fetal Medicine (SMFM) to predict placental histopathological findings associated with placental insufficiency and a composite adverse neonatal outcome (ANeO). STUDY DESIGN In this retrospective cohort study of singleton pregnancies, the ISUOG and the SMFM guidelines were used to identify pregnancies with FGR and a corresponding control group. The primary outcome was the prediction of placental histopathological findings associated with placental insufficiency, defined as lesions associated with maternal vascular malperfusion (MVM). A composite ANeO (ie, umbilical artery pH≤7.1, Apgar score at 5 minutes ≤4, neonatal intensive care unit admission, hypoglycemia, respiratory distress syndrome requiring mechanical ventilation, intrapartum fetal distress requiring expedited delivery, and perinatal death) was investigated as a secondary outcome. Sensitivity, specificity, positive and negative predictive values, and the areas under the receiver-operating-characteristics curves were determined for each FGR definition. Logistic regression models were used to assess the association between each definition and the studied outcomes. A subgroup analysis of the diagnostic performance of both definitions stratifying the population in early and late FGR was also performed. RESULTS Both societies' definitions showed a similar diagnostic performance as well as a significant association with the primary (ISUOG adjusted odds ratio 3.01 [95% confidence interval 2.42, 3.75]; SMFM adjusted odds ratio 2.85 [95% confidence interval 2.31, 3.51]) and secondary outcomes (ISUOG adjusted odds ratio 1.95 [95% confidence interval 1.56, 2.43]; SMFM adjusted odds ratio 2.12 [95% confidence interval 1.70, 2.65]). Furthermore, both FGR definitions had a limited discriminatory capacity for placental histopathological findings of MVM and the composite ANeO (area under the receiver-operating-characteristics curve ISUOG 0.63 [95% confidence interval 0.61, 0.65], 0.59 [95% confidence interval 0.56, 0.61]; area under the receiver-operating-characteristics SMFM 0.63 [95% confidence interval 0.61, 0.66], 0.60 [95% confidence interval 0.57, 0.62]). CONCLUSION The ISUOG and the SMFM FGR definitions have limited discriminatory capacity for placental histopathological findings associated with placental insufficiency and a composite ANeO.

Abstract
INTRODUCTION Placental vascular disease, characterized by Maternal Vascular Malperfusion (MVM) lesions, is considered to be the underlying cause of pregnancy complications. Aim is to evaluate the relationship between the cumulative number of MVM lesion types, and adverse pregnancy- and neonatal outcomes. METHODS This retrospective cohort study included 272 women with singleton gestations who gave birth at a Dutch tertiary hospital between 2017 and 2018 with available placental histopathology reports. Analyzed according to the Amsterdam Placental Workshop Group Consensus Statement, placentas were divided into groups based on the cumulative number of MVM lesions: no lesions (n = 124), 1-2 types (n = 124) and 3-5 types of lesions (n = 24). RESULTS The proportion of placenta syndrome (PS) was highest (95.8%) in the 3-5 MVM lesions group (p < 0.001). The presence of MVM lesions was highly associated with PS during pregnancy (aOR 6.81, 95% CI 3.76-12.33). Furthermore, every additional type of MVM lesion corresponded with a threefold increased odds for the occurrence of PS (aOR 3.00, 95% CI 2.10-4.29). The group with 3-5 types of MVM lesions showed the highest incidence of adverse neonatal outcomes, lower mean birth weight, prolonged hospitalization, NICU admissions and neonatal deaths (aOR 6.47, 95% CI 0.33-127.68), corresponding with a fourfold increased odds for the occurrence of neonatal death for every additional MVM lesion (aOR 4.19, 95% CI 1.39-12.68). DISCUSSION A higher number of MVM lesion types is strongly associated with an increased incidence of adverse pregnancy- and neonatal outcomes, indicating that guidelines should focus also on the amount of MVM lesion types for the monitoring/management of subsequent pregnancies.

Abstract
INTRODUCTION We aimed to investigate the effect of maternal passive smoking (MPS) during pregnancy-on placental pathology and pregnancy outcomes. METHODS A prospective case-control study. We recruited low-risk laboring women at 37+0-41 + 0 weeks between 9/2019-7/2020. MPS was defined as exposure to in-house spouse tobacco smoking of >20 cigarettes/day in the absence of maternal active-smoking. In attempt to "purify" the effect of MPS on placental pathology-we excluded cases with preeclampsia, diabetes, suspected fetal growth restriction (FGR), preterm labor, and illicit drug use. Maternal characteristics, pregnancy outcomes, and placental pathology were compared between the MPS group and a control group matched for gestational age, maternal age, and delivery date. Placental lesions were classified according to the "Amsterdam" criteria. The study was powered to detect a 33% difference in placental malperfusion lesions. Multivariable regression was performed to identify independent associations with placental malperfusion lesions. RESULTS In labor, the MPS group (n = 115) had higher rates of meconium stained amniotic fluid (MSAF, p < 0.001) and non-reassuring fetal heart-rate (NRFHR,p = 0.006), compared to controls (n = 115). Neonates in the MPS group had higher rates of undiagnosed FGR (p = 0.01) and NICU admissions (p = 0.004). The MPS group had higher rates of placental-hypoplasia (p = 0.02) and fetal vascular malperfusion (FVM) lesions (p = 0.04). In regression analysis MPS was associated with FVM lesions independent of background confounders (aOR = 1.24 95% CI 1.10-2.65). DISCUSSION In otherwise low-risk pregnancies, MPS was associated with higher rates of MSAF, NRFHR, undiagnosed FGR, and NICU admissions, probably mediated via placental FVM. These worrisome findings mandate patient counseling and further investigation in larger population-based studies.

Abstract
RESEARCH QUESTION To assess whether the incidence of placental disorders of pregnancy decreases with increasing parity in repeat IVF pregnancies, in the same way as natural pregnancies. DESIGN This was a retrospective cohort of deliveries between November 2008 and January 2020, in a single university-affiliated medical centre. The study included women with only IVF-attained singleton pregnancies (no natural conception) with at least two deliveries, and compared the obstetric and perinatal outcomes between first, second and third deliveries. Each woman served as her own control. The primary outcome was the incidence of placental-related disorders of pregnancy, defined as small for gestational age (SGA) neonates and/or pre-eclampsia. RESULTS A total of 307 first deliveries, 307 second deliveries and 49 third deliveries by the same women were compared. A trend for a decreased rate of pre-eclampsia was noted with increased parity (P = 0.06) and a significant decrease in the rate of SGA: 11.7% for first delivery, 7.8% for second delivery and 2.0% for third (P = 0.04). This difference in SGA incidence was maintained in a matched sub-analysis of the 49 women with three deliveries (P = 0.04), and after adjustment for fresh/frozen embryo transfer (P = 0.03). Although SGA and pre-eclampsia were generally more common in IVF than natural pregnancies, their decrease with increasing parity mimicked that in natural pregnancies. CONCLUSION IVF pregnancies are associated with an increased risk of placental disorders of pregnancy. However, they exhibit a decrease in incidence with increasing parity.

Abstract
INTRODUCTION We aimed to investigate the effect of placental histologic chorioamnionitis (HC) on neonatal outcomes in pregnancies complicated by fetal growth restriction (FGR). METHODS - The computerized medical files of all pregnancies diagnosed with FGR (birthweight <10th percentile) at 24-42 weeks of gestation between 2008 and 2019 were reviewed. Maternal and neonatal outcomes were compared between FGR with and without evidence of placental HC. Placental lesions were classified according to "Amsterdam" criteria. Composite adverse neonatal outcome-included any of the following complications: neurological morbidity, neonatal respiratory assistance, RDS, NEC, sepsis, blood transfusion, phototherapy, hypoglycemia, or neonatal death. Composite severe adverse neonatal outcome included any of the following complications - neurological morbidity, blood transfusion, NEC, sepsis, RDS, neonatal death. RESULTS - Compared to FGR without HC (n = 446), FGR with HC (n = 57) was characterized by more advanced gestational age at delivery 39.2 (38.3-39.9) vs. 38.2 (36.9-39.2), weeks respectively, p < 0.001), higher rate of nulliparity (73.7% vs. 45.1%, p < 0.001), less vascular lesions of MVM (1.8% vs.11.2%, p = 0.02), higher rate of Apgar scores at 5 min <7 (10.5% vs. 2%, p = 0.004), increased neonatal death (7.0% vs. 0.9%, p = 0.007), higher rates of both composite adverse neonatal outcome (31.1% vs. 17.3% p = 0.02), and composite severe adverse neonatal outcome (16.3% vs. 8.2% p = 0.04). By multivariate regression analysis HC was found to be independently associated with composite adverse neonatal outcome (aOR = 1.21, 95% CI 1.08-2.38) and with severe composite adverse neonatal outcome (aOR = 1.39, 95% CI 1.16-3.76). CONCLUSIONS Pregnancies complicated by FGR with concomitant HC were associated with higher rates of adverse neonatal outcomes.

Fetal Growth Restriction in Hypertensive vs. Heavy Smoking Women-Placental Pathology, Ultrasound Findings, and Pregnancy Outcomes. Reprod Sci 2020; 28:819-827. [PMID: 33140325 DOI: 10.1007/s43032-020-00373-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Accepted: 10/21/2020] [Indexed: 11/30/2022]
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.

Abstract
OBJECTIVE The aim of our study is to establish the reference range of Young's modulus values of placenta in normal pregnancies and to evaluate the diagnostic value of two-dimensional shear wave elastography (2D-SWE) in gestational diabetes mellitus (GDM). METHODS A total of 223 normal pregnant women, 22 pregnancies complicated by A1GDM (controlled by diet), and 14 pregnancies complicated by A2GDM (controlled by medication) were recruited for this study. The elasticity values of the central parts of the placentas were determined by 2D-SWE imaging. The mean value (Emean), min value (Emin), and max value (Emax) of the placentas were recorded. Twenty placentas were randomly selected for reliability analysis. RESULTS (1) All values (Emean, Emin, Emax) showed great repeatability and consistency. (2) The reference range of Young's modulus values of placentas in normal pregnancies were Emean (4.12 ± 0.83), Emin (2.15 ± 0.83) and Emax (6.72 ± 1.43). No significant correlations were observed between elasticity values and gestational age (r < 0.3, p > 0.05) or between elasticity values and placental maturity (r < 0.3, p > 0.05). (3) The Young's modulus values in the A1 GDM and A2 GDM women were Emean (6.39 ± 1.74), Emin (2.95 ± 1.05), Emax (10.78 ± 2.94) and Emean (11.96 ± 7.29), Emin (6.79 ± 4.70a), Emax (18.94 ± 11.61) respectively. All values were significantly higher in GDM pregnancies than in normal pregnancies (p < 0.05). A2GDM pregnancies had higher values than A1GDM pregnancies (p < 0.05). CONCLUSION Placental elasticity is independent of gestational age and placental maturity. 2D-SWE can play an important role in diagnosing GDM by assessing placental hardness.

Eur J Obstet Gynecol Reprod Biol 2020; 254:188-194. [PMID: 33007579 DOI: 10.1016/j.ejogrb.2020.09.039] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 09/16/2020] [Accepted: 09/21/2020] [Indexed: 12/25/2022]
Abstract
INTRODUCTION We aimed to study the correlation between the extent of placental abruption (PA), as grossly estimated immediately after delivery, and pregnancy outcomes, in correlation with placental histopathology. MATERIALS AND METHODS Pregnancy and placental reports of all pregnancies complicated by PA (clinically diagnosed) between 11/2008-12/2018 were reviewed. We compared maternal background, pregnancy outcomes, and placental histopathology between cases of PA divided into three groups according to the extent of abruption: Group 1-<30 %, Group 2-30-49 %, and Group 3->50 % of placental surface. Placental lesions were classified according to the current "Amsterdam" criteria. The primary outcome was defined as a composite of severe neonatal morbidity and included ≥ 1 of the following complications: seizures, intraventricular hemorrhage, hypoxic-ischemic encephalopathy, periventricular leukomalacia, blood transfusion, necrotizing enterocolitis, intrauterine fetal demise, or neonatal death. RESULTS A total of 260 PA cases were included: 111 (42.7 %) in Group 1, 94 (36.2 %) in Group 2, and 55 (21.1 %) in Group 3. The rate of the primary outcome (7.2 % vs. 11.7 % vs. 27.3 %, p = 0.02) was associated with the degree of PA as well as maternal heavy smoking (p = 0.04), DIC (p = 0.03), umbilical artery Ph <7.1 (p = 0.02), 5-minute Apgar scores <7 (p = 0.03), NICU admissions, placental maternal vascular malperfusion lesions (p = 0.04), and neonatal weights <5th percentile (0.04). In multivariable analysis severe adverse neonatal outcome was independently associated with the percentage of PA (aOR = 1.4, 95 % CI = 1.3-3.9). CONCLUSION The extent of placental abruption, as estimated by the examiner, correlated with DIC and severe neonatal outcomes and may serve as an early alarming sign in deliveries complicated by PA.

Placental Histopathology and Pregnancy Outcomes in "Early" vs. "Late" Placental Abruption. Reprod Sci 2020; 28:351-360. [PMID: 32809128 DOI: 10.1007/s43032-020-00287-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 08/02/2020] [Indexed: 10/23/2022]
Abstract
Placenta-associated pregnancy complications (fetal growth restriction and preeclampsia) are traditionally classified as "early" and "late" due to their different pathophysiology, histopathology, and pregnancy outcomes. As placental abruption (PA) represents another placenta-associated complication, we aimed to study if this categorization can be applied to PA as well. Pregnancy and placental reports of all pregnancies complicated by PA between November 2008 and January 2019 were reviewed. Maternal background, pregnancy outcomes, and placental histopathology were compared between cases of PA < 34 weeks (early PA group) vs. > 34 weeks (late PA group). Placental lesions were classified according to the "Amsterdam" criteria. The primary outcome was severe neonatal morbidity (≥ 1 severe neonatal complications: seizures, IVH, HIE, PVL, blood transfusion, NEC, or death). Included were 305 cases of PA, 71 (23.3%) in the early group and 234 (76.7%) in the late group. The early PA group was characterized by higher rates of vaginal bleeding upon presentation (p = 0.003), DIC (p = 0.018), and severe neonatal morbidity (p < 0.001). The late PA group was characterized by a higher rate of urgent Cesarean deliveries (p < 0.001). The early PA group was characterized by higher rates of placental maternal vascular malperfusion (MVM) lesions (p < 0.001), maternal inflammatory response (MIR) lesions (p < 0.001), placental hemorrhage (p < 0.001), and a lower feto-placental ratio (p < 0.001). Using regression analysis, we found that severe neonatal morbidity was independently associated with early abruption (aOR = 5.3, 95% CI = 3.9-7.6), placental MVM (aOR = 1.5, 95% CI = 1.2-1.9), placental MIR (aOR = 1.9, 95% CI = 1.4-2.3), and inversely associated with antenatal corticosteroids (aOR = 0.9, 95% CI = 0.6-0.98). "Early" and "late" PA significantly differ in their presentation, placental pathology, and pregnancy outcomes.

Preeclampsia in Different Maternal Age Groups-Is There an Association with Pregnancy Outcomes and Placental Pathology? Reprod Sci 2020; 27:1879-1887. [PMID: 32562243 DOI: 10.1007/s43032-020-00207-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Accepted: 04/23/2020] [Indexed: 11/27/2022]
Abstract
We aimed to compare maternal characteristics, pregnancy outcomes, and placental pathology in pregnancies complicated by preeclampsia at three different maternal age groups. Medical records and pathological reports of patients diagnosed with preeclampsia and delivered between 2008 and 2018 in a single tertiary center, were reviewed. Preeclampsia was diagnosed according to the current ACOG guidelines. Study population was divided into 3 groups of maternal age: group 1-< 27 years; group 2-27-35 years; and group 3-> 35 years (advanced maternal age = AMA). Data regarding maternal characteristics, neonatal outcomes, and placental histopathological lesions were compared between the groups. Composite adverse neonatal outcome was defined as ≥ 1 early neonatal complication. The AMA group (n = 145) was associated with a higher BMI, and higher rates of diabetes mellitus (DM), chronic hypertension (CHTN), and Cesarean deliveries compared with group 1 (n = 107) and group 2 (n = 255). The AMA group also had lower neonatal birthweights and a higher rate of composite adverse neonatal outcome compared with the other age groups. None of the placental lesions differed between the groups. By multivariable analysis, we found that maternal age (aOR 1.36, 95% CI 1.17-3.93), GA at delivery (aOR 0.80, 95% CI 0.61-0.90), DM (aOR 1.19, 95% CI 1.07-3.05), and CHTN (aOR 1.23, 95% CI 1.08-2.01) were independently associated with composite adverse neonatal outcome. Pregnancies at AMA were associated with higher complication rates, but without any differences in placental pathology, suggesting that the worse outcomes associated with AMA in preeclampsia are attributed to maternal chronic morbidities and not to differences observed in placental pathology.

Abstract
OBJECTIVE In an attempt to shed new light on the pathogenesis of fetal growth restriction (FGR), we aimed to study pregnancy characteristics, neonatal outcomes, and placental histopathological lesions of FGR pregnancies in two different subgroups: when developed after appropriate for gestational age (AGA) pregnancy and when developed after previous pregnancy with FGR. STUDY DESIGN Pregnancy and placental reports of all singleton pregnancies complicated by FGR (defined as actual birthweight below the 10th percentile according to local birthweight nomograms) between 2008 and 2018 were reviewed. Included were only cases with previous delivery. Maternal background, neonatal outcomes, and placental histopathology were compared between FGR that occurred after FGR (recurrent FGR group) and FGR that occurred after an AGA pregnancy (FGR after AGA group). Placental lesions were classified according to the current "Amsterdam" criteria. Continuous variables were compared using the Student's t test or the Mann-Whitney test as appropriate. Categorical variables were compared using Chi-square or Fisher's exact test as appropriate. RESULTS A total of 334 FGR cases with a previous delivery were included in the study. Of them, 111 cases constituted the recurrent FGR group and 223 constituted the FGR after AGA group. The recurrent FGR group was characterized by higher rates of maternal diabetes during pregnancy and hypertensive diseases (9% versus 2.7%, p = 0.01 and 19.8% versus 11.6%, p = 0.04). The FGR after AGA group was characterized by a higher rate of fetal vascular malperfusion (FVM) lesions (29.6% versus 18.0%, p = 0.02), and by lower mean birthweight (1842 ± 424.9 versus 1977.4 ± 412.2, p = 0.005), as compared to the recurrent FGR group. CONCLUSION Recurrent FGR was associated with maternal background morbidities during pregnancy which represents a chronic repeated insult, while "new" FGR cases (those followed an AGA pregnancy) were characterized by a higher rate of FVM lesions and lower birthweight which probably represent an "accident" in placentation. These findings may suggest that different mechanisms of placental dysfunction exist in the two subgroups of FGR.

Abstract
PURPOSE To study whether placentas of singleton pregnancies conceived after fresh embryo transfer (ET) contain more histopathological lesions compared with placentas of singleton pregnancies conceived after frozen-thawed embryo transfer (FET). METHODS A prospective cohort study of placental histopathology in 131 women with singleton IVF pregnancies who delivered at a single medical center, between December 2017 and May 2019. The prevalence of different placental histopathology lesions was compared between women who conceived after fresh ET and FET. RESULTS Women who conceived after fresh ET (n = 74) did not differ from women who conceived after FET (n = 57) with regard to maternal age, BMI, nulliparity, or infertility diagnosis. Gestational week at delivery was lower in pregnancies conceived after fresh ET (38.5 vs. 39.2 weeks, respectively, p = 0.04), and a trend for a lower birthweight following fresh ET was noted (3040 vs. 3216 g, respectively, p = 0.053). However, placental histopathology analysis from pregnancies conceived after fresh ET was comparable to pregnancies conceived after FET, with regard to the prevalence of maternal vascular malperfusion lesions (45.9% vs. 50.9%, respectively, p = 0.57), fetal vascular malperfusion lesions (17.6% vs. 21.1, p = 0.61), acute inflammatory response lesions (28.4% vs. 28.1%, respectively, p = 0.96), and chronic inflammatory response lesions (13.5% vs. 8.8%, respectively, p = 0.48). CONCLUSION Placental histopathology did not differ between IVF pregnancies conceived after fresh and frozen ET. These results are reassuring for clinicians and patients who wish to pursue with transferring fresh embryos.

Eur J Obstet Gynecol Reprod Biol 2020; 246:165-168. [PMID: 32032929 DOI: 10.1016/j.ejogrb.2020.01.050] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 01/24/2020] [Accepted: 01/31/2020] [Indexed: 10/25/2022]
Abstract
OBJECTIVE Reduced fetal movements (RFM) is an obstetric complaint known to be associated with adverse neonatal outcomes and should serve as an alarming sign in obstetric triage. Whether this assumption holds for twin pregnancies, is still an obstetric enigma, and this complaint is sometimes overlooked in twins. We, therefore, aimed to study neonatal outcomes in twin pregnancies complicated by RFM. We hypothesised that in twin pregnancy, maternal ability to perceive RFM will be limited, and therefore, will not be associated with adverse neonatal outcome. STUDY DESIGN Included were all dichorionic twin pregnancies between 2009-2019 who presented to our obstetric triage at a gestational age >34 weeks with an isolated complaint of RFM and delivered during the subsequent two weeks (RFM group). The control group included patients with twin pregnancies (matched for gestational age and maternal age) who presented for routine assessment and reported regular fetal movements throughout pregnancy (no RFM group). Data regarding pregnancy, delivery, and neonatal outcomes were compared between the groups. The primary outcome was a composite of adverse neonatal outcomes, which included one or more of the following: neonatal hypoglycemia, respiratory morbidity, cerebral morbidity, phototherapy, neonatal sepsis, blood transfusions, necrotizing enterocolitis, or neonatal death. Multivariable regression analysis was used to identify independent associations with adverse neonatal outcomes. RESULTS Maternal demographics and gestational age at delivery did not differ between the RFM group (n = 83 pregnancies and 166 neonates) and the no RFM group (n = 83 pregnancies and 166 neonates). Neonatal birthweights, as well as the rate of birthweights <10th centile, did not differ between the groups. There were 2 cases of fetal demise diagnosed at triage in the RFM group. The rate of the primary outcome, as well as NICU admissions, were significantly higher in the RFM group compared to the no RFM group (29.5 % vs. 19.2 %, p = 0.01 and 32.5 % vs. 19.2 %, p = 0.001). In multivariable analysis RFM (aOR = 1.18, 95 % CI = 1.06-2.73), and GA at delivery (aOR = 0.88, 95 % CI = 0.67-0.97) were associated with adverse neonatal outcome-independent from background confounders. CONCLUSION Patients presented to obstetric triage with twin pregnancies and isolated RFM had higher rates of adverse neonatal outcomes and NICU admissions compared to twin pregnancies without RFM.

Maternal vascular malformation in the placenta is an indicator for fetal growth restriction irrespective of neonatal birthweight. Placenta 2019; 87:8-15. [PMID: 31520871 DOI: 10.1016/j.placenta.2019.09.003] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 08/12/2019] [Accepted: 09/04/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION To study the association between placental pathology and neonatal birthweight and outcomes, and whether a combination of first trimester biomarkers and fetal growth velocity can predict placental lesions. METHODS The presence of maternal vascular malperfusion (MVM) lesions (Amsterdam criteria) was recorded in a retrospective cohort of singleton pregnancies in the Maastricht University Medical Centre, 2011-2018. First trimester maternal characteristics and PAPP-A, PlGF and sFlt-1 levels were collected. Fetal growth velocities were calculated (mm/week) from 20 to 32 weeks for abdominal circumference, biparietal diameter, head circumference and femur length. Data were compared between neonates with 'small for gestational age' (SGA < p10) and different categories of 'appropriate for gestational age (AGA)': AGAp10-30, AGAp30-50 and AGA > p50 (reference), using one-way ANOVA and post hoc test. RESULTS There were significantly more MVM lesions in the SGA group (94.6% p < .0001), but also in the AGAp10-30 (67.3% p < .0001) and AGAp30-50 (41.6% p = 0.002), compared to the reference AGA group (19.3%). The prediction of MVM for a 20% false-positive rate, with maternal characteristics was25.2%. The addition of birthweight percentile gave a prediction of 51.7% for MVM. However adding placental biomarkers and fetal growth velocities (instead of birthweight percentile) to the maternal characteristics, gave a prediction of 81.8% (PPV 49.5%, NPV 53.7%). DISCUSSION Placental MVM lesions correlated inversely with birthweight even in AGA neonates, and was associated with slower fetal growth and more adverse outcome in SGA neonates. A combination of first trimester biomarkers and fetal growth velocity had good prediction of placental MVM lesions, as an indicator of fetal growth restriction irrespective of neonatal weight.
