Abstract
Abnormal functions of trophoblast cells are associated with the pathogenesis of preeclampsia (PE). Nuclear receptor subfamily 2 group F member 1 (NR2F1) acts as a transcriptionally regulator in many diseases, but its role in PE remains unknown. Hypoxia/reoxygenation (H/R)-stimulated HTR-8/SVneo cells were used to mimic PE injury in vitro. NR2F1 overexpression alleviated trophoblast apoptosis, as evidenced by the decreased number of TUNEL-positive cells and the downregulation of caspase 3 and caspase 9 expression in cells. NR2F1 overexpression increased the invasion and migration ability of HTR-8/SVneo cells, accompanied by increased protein levels of matrix metalloproteinase (MMP)-2 and MMP-9. mRNA-seq was applied to explore the underlying mechanism of NR2F1, identifying growth differentiation factor 15 (GDF15) as the possible downstream effector. Dual-luciferase reporter, ChIP-qPCR, and DNA pull-down assays confirmed that NR2F1 bound to the promoter of GDF15 and transcriptionally inhibited its expression. GDF15 overexpression increased apoptosis and decreased the ability of invasion and migration in HTR-8/SVneo cells expressing NR2F1. MAPK pathway was involved in the regulation of PE. Administration of p38 inhibitor, ERK inhibitor, and JNK inhibitor reversed the effect of simultaneous overexpression NR2F1 and GDF15 on trophoblast apoptosis, invasion, and migration. Our findings demonstrated that NR2F1 overexpression inhibited trophoblast apoptosis and promoted trophoblast invasion and migration. NR2F1 might negatively regulate GDF15 expression by binding to its promoter region, which further inhibited MAPK signaling pathway in PE. Our study highlights that NR2F1 might sever as a potential target in PE.

Abstract
Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal conditions affecting 6 to 10% of low-birth-weight infants and remains a leading cause of death. The risk factors associated with NEC are complex and multifactorial, including preterm birth and intrauterine exposure to inflammation and hypoxia. Chorioamnionitis has been associated with intestinal injury in animal and human clinical studies. This review presents current evidence about the clinical impact of the intrauterine environment on intestinal injury during pregnancy and postpregnancy. We present information from our own clinical and laboratory research in conjunction with information collected from an extensive search in the databases PubMed, EMBASE, and Scopus. Prospective multicenter studies, including accurate and precise clinical, maternal, and laboratory predictors (e.g., inflammatory biomarkers), will help identify the mechanisms associated with the placental pathology, the development of NEC, and the impact of in utero-triggered inflammation on the clinical outcomes. Filling the knowledge gap to link the inflammatory surge to postnatal life will aid in identifying at-risk infants for NEC in a timely manner and facilitate the development of novel immunomodulatory treatments or interventions to improve the outcomes of these vulnerable infants. KEY POINTS: · Placental inflammatory and vascular lesions are associated with NEC severity.. · Higher grade chorioamnionitis with a fetal response is associated with an increased risk of surgical NEC.. · There is a need for routine bedside utilization of placenta pathology in clinical decision-making..

Abstract
Introduction: Hypertensive disorders of pregnancy continue to pose the most important risks for adverse maternal and neonatal outcome. Among histological findings, decidual artery disease is one of the most common, one that has both good reproducibility among observers and whose abnormal vascular remodeling is the sole aspect of preeclampsia pathophysiology on which experts agree. Nevertheless, some aspects of arterial remodeling alterations are still under investigation. Methods: We selected 720 routine and consecutive placenta case studies, concordant with the Amsterdam consensus. From these studies, we collected maternal and neonatal clinical data and specific placental findings on spiral artery abnormalities. We took into account all criteria for decidual arteriopathy. Two hundred and fifteen (215) cases out of this population presented hypertensive disorders of pregnancy. Additional to expected arterial findings, we noted frequent persistent parietal trophoblast lining. Results: A large proportion of our population developed hypertensive disorders of pregnancy (30%). Among the histologic findings reported for preeclampsia, we paid particular attention to spiral artery abnormalities, and this interpretive analysis revealed high frequency of arterial remodeling abnormalities. We examined two additional aspects in our routine analysis: first, the novel one of parietal trophoblast persistence, and second, the established problem of associated acute inflammation, as a possible pitfall. Conclusion: In order to better understood, spiral maternal artery remodeling merits further study. The abnormalities in this process provide an objective tool in the study and diagnosis of important pregnancy complications; furthermore, abnormal remodeling is an expression of early pregnancy alteration, and subsequently related to preeclampsia etiology.

Abstract
OBJECTIVE To determine the association of placental pathology with the severity of necrotizing enterocolitis (NEC) in preterm infants. METHODS This single-center matched case-control study included infants with NEC (n = 107) and gestational age and birth weight-matched controls (n = 130), born between 2013 and 2020. Placentas were evaluated according to the Amsterdam Placental Workshop Group Consensus Statement. RESULTS Acute histologic chorioamnionitis with the fetal response was significantly more common in infants with surgical NEC vs. medical NEC (35.4% vs. 15.3%; p = 0.02). On regression model, infants with multiple placental pathologies (OR 2.16; 95% CI 1.01 - 4.73; p = 0.04) and maternal vascular malperfusion (OR 2.2; 95% CI 1.12 - 4.51; p = 0.02) had higher odds of either medical or surgical NEC than controls. CONCLUSION Infants with multiple placental lesions, including placental inflammatory and vascular lesions, were at higher risk of medical or surgical NEC in the postnatal period.

Abstract
Obesity is a risk factor for severe COVID-19 disease during pregnancy. We hypothesized that the co-occurrence of high maternal body mass index (BMI) and gestational SARS-CoV-2 infection are detrimental to fetoplacental development. We conducted a systematic review following PRISMA/SWiM guidelines and 13 studies were eligible. In the case series studies (n = 7), the most frequent placental lesions reported in SARS-CoV-2(+) pregnancies with high maternal BMI were chronic inflammation (71.4%, 5/7 studies), fetal vascular malperfusion (FVM) (71.4%, 5/7 studies), maternal vascular malperfusion (MVM) (85.7%, 6/7 studies) and fibrinoids (100%, 7/7 studies). In the cohort studies (n = 4), three studies reported higher rates of chronic inflammation, MVM, FVM and fibrinoids in SARS-CoV-2(+) pregnancies with high maternal BMI (72%, n = 107/149; mean BMI of 30 kg/m2) compared to SARS-CoV-2(−) pregnancies with high BMI (7.4%, n = 10/135). In the fourth cohort study, common lesions observed in placentae from SARS-CoV-2(+) pregnancies with high BMI (n = 187 pregnancies; mean BMI of 30 kg/m2) were chronic inflammation (99%, 186/187), MVM (40%, n = 74/187) and FVM (26%, n = 48/187). BMI and SARS-CoV-2 infection had no effect on birth anthropometry. SARS-CoV-2 infection during pregnancy associates with increased prevalence of placental pathologies, and high BMI in these pregnancies could further affect fetoplacental trajectories.

Abstract
Background: Histopathological evaluation of the first trimester pregnancy loss has always been controversial. Although it is recommended, it is not a part of guidelines.Methods: Six hundred eighty-six samples in a referral infertility clinic were evaluated microscopically and categorized. Two hundred ninety-five cases were evaluated by genetic methods (Multiplex Ligation-dependent Probe Amplification).Results: From 569 samples with chorionic villi, 361 cases had history of three or more abortions. 18.3% of this group showed chronic intervillous of unknown etiology (CIUE) and 8.3% revealed intervilli fibrin deposition, both pathologies with a high risk of recurrence. History of a live child was significantly higher in CIUE group. 29% of genetically evaluated cases had a chromosomal abnormality.Conclusion: Histological evaluation of recurrent pregnancy loss could illuminate the cause of abortion in relatively acceptable percentage of cases, especially in mothers with higher number of previous abortion, mothers with a history of live child and in referral centers.

Abstract
BACKGROUND To determine the association of placental pathologic lesions with postoperative outcomes, survival, and white matter injury (WMI) in preterm infants with NEC. METHODS A retrospective chart review of 107 neonates with NEC (Bell stage > IIa) from Jan 2013- June 2020 was completed. Demographic, clinical, and outcome data were compared between infants with or without placental pathologic lesions. RESULTS In this cohort, 59/107 (55%) infants had medical NEC, and 48 (45%) had surgical NEC. The infants had a mean gestational age of 28.1±3.7 weeks and a birth weight of 1103±647 g. Maternal vascular malperfusion (82/107, 76.6%) and acute histological chorioamnionitis (42, 39.3%) were the most common pathological placental lesions. Acute histologic chorioamnionitis with fetal inflammatory response was more common in infants with surgical NEC vs. medical NEC (35.4% vs. 15.3%; p = 0.02). The NEC Infants with WMI on brain MRI scans had a significantly higher incidence of acute histological chorioamnionitis (52% vs. 27.8%; P = 0.04). No significant differences in mortality, length of stay and postoperative outcomes in neonates with and without acute histologic chorioamnionitis with fetal inflammatory response were noted. On unadjusted logistic regression, acute histologic chorioamnionitis without fetal inflammatory response was also associated with higher odds of WMI (OR 2.81; 95% CI 1.05-7.54; p = 0.039). CONCLUSION Acute histological chorioamnionitis without fetal inflammatory response was associated with higher odds of WMI in infants with NEC, with no significant impact on mortality and other postoperative outcomes.

Abstract
There is widespread acceptance of the increased prevalence of cardiovascular diseases occurring within 1 to 2 decades in women following a preeclamptic pregnancy. More recent evidence suggests that the deranged biochemical and echocardiographic findings in women do not resolve in the majority of preeclamptic women following giving birth. Many women continue to be hypertensive in the immediate postnatal period with some exhibiting occult signs of cardiac dysfunction. There is now promising evidence that with close monitoring and effective control of blood pressure control in the immediate postnatal period, women may have persistently lower blood pressures many years after stopping their medication. This review highlights the evidence that delivering effective medical care in the fourth trimester of pregnancy can improve the long-term cardiovascular health after a preeclamptic birth.

Abstract
Preeclampsia, a multisystem pregnancy-specific hypertensive disorder, results in significant maternal and perinatal morbidity and mortality. This condition is associated with placental histopathological abnormalities and particularly affects the decidual spiral arteries. Reportedly, aspirin prevents preeclampsia, specifically early-onset preeclampsia, although findings in decidual arteries in women treated with aspirin therapy remain unclear. We compared the clinical and histopathological placental findings between women with a history of preeclampsia, who did and did not receive low-dose aspirin therapy (LDA and non-LDA groups, respectively). We identified 26 women with a history of preeclampsia; 9 women received LDA (aspirin ≤ 100 mg/day, initiated at < 16 weeks, LDA group), and 17 women did not receive LDA (non-LDA group). The mean gestational age was higher (36.7 weeks vs. 32.3 weeks, P = 0.0221) and the incidence of preeclampsia was lower (11% vs. 59%, P = 0.0362) in the LDA than in the non-LDA group. Histopathologically, the incidence of decidual arteriopathy, particularly that of fibrinoid necrosis and thrombosis, was lower in the LDA than in the non-LDA group (44% vs. 88%, P = 0.0283). Immunohistologically, endothelial marker (CD31 and CD39) expression was stronger in the LDA than in the non-LDA group. Notably, we observed no significant intergroup differences in inflammatory changes (chronic perivasculitis, protease-activated receptor 1 expression, and CD3-positive cells). This study highlights that LDA inhibits hypertension-induced endothelial injury and thrombosis, and thereby protects maternal placental perfusion and prevents preeclampsia.

Abstract
INTRODUCTION Placental syndrome is an umbrella term encompassing the clinical phenotypes of preeclampsia and fetal growth restriction, and is associated with high maternal and neonatal morbidity. In women with placental syndrome, histologicl examination of the uteroplacental unit commonly demonstrates pathological lesions, such as decidual vasculopathy. Decidual vasculopathy are pathological changes in the spiral arteries, which are associated with adverse outcome in preeclampsia and long-term maternal cardiovascular health. The relation between placental syndrome phenotypes and placental pathology has been previously demonstrated; however, the role of uteroplacental Doppler measurements as a link between placental syndrome phenotypes and the underlying placental pathology is still unclear. We hypothesized that decidual vasculopathy is associated with abnormal uteroplacental Doppler profiles and ultrasound placental parameters, independent of clinical phenotype. MATERIAL AND METHODS We performed a retrospective analysis of data from a prospective cohort of pregnancies with placental syndrome, as well as cases without hypertensive disease or fetal growth restriction. The study group was divided into women with decidual vasculopathy on histologic analysis of placental specimen and those without the lesions. Outcome parameters included maternal and fetal Dopplers, estimated fetal weight, placental weight and thickness, placental lacunae and abnormal placental calcification. RESULTS Compared with the women without the lesions (n = 91), the group with decidual vasculopathy (n = 25) had a higher mean uterine artery pulsatility index (1.70 vs 0.81, p < 0.001) and uterine artery pulsatility index percentile (>p99 vs p67, p < 0.001). Decidual vasculopathy was associated with abnormal uterine artery Doppler profile (defined as pulsatility index p > 95 and/or bilateral notch) (82%) compared with women without the lesions (33%) (odds ratio [OR] 9.3, 95% CI 2.4-36.0), which remained significant after adjusting for possible confounding factors preeclampsia, tobacco use and gestational age at birth (OR 7.1, 95% CI 1.3-39.1). Decidual vasculopathy was not associated with fetal Doppler abnormalities or placental parameters and only modestly so with lower cerebroplacental ratio (p = 0.036). CONCLUSIONS Histologic decidual vasculopathy is associated with abnormal uterine artery Doppler, independent of clinical phenotype during pregnancy.

Abstract
CONTEXT.— There are 3 types of decidual vasculopathy, namely, acute atherosis, fibrinoid medial necrosis, and mural arterial hypertrophy. Persistence of vascular trophoblasts is also known to be related to maternal vascular malperfusion, but detailed study is lacking. OBJECTIVE.— To define atherosis of trophoblast type and distinguish it from atherosis of macrophage type with clinical significance. DESIGN.— A total of 1322 placentas from 2021 were collected with clinical, neonatal, and placental information, and routine placental pathology examination was performed. Decidual vasculopathy was classified on the basis of the new classification scheme including atherosis of macrophage type, atherosis of trophoblast type, fibrinoid medial necrosis, mural arterial hypertrophy, and mixed-type vasculopathy. The significance of these morphologic changes was examined on the basis of clinical, neonatal, and placental pathology features. RESULTS.— Decidual vasculopathy is classified as classic type, mural hypertrophy, and mixed type. Classic-type vasculopathy is further separated as atherosis and fibrinoid medial necrosis. Atherosis is defined as atherosis of macrophage type and atherosis of trophoblast type. Each category of decidual vasculopathy was evaluated in association with maternal, neonatal, and placental pathologic findings. Atherosis of macrophage type and mixed-type vasculopathy showed statistically significant association with preeclampsia/pregnancy-induced hypertension (PIH), low birth weight, and low placental weight. Atherosis of trophoblast type was associated with lower placental weight but not with other specific clinical features. Neonates of female sex were associated with mural arterial hypertrophy. CONCLUSIONS.— Atherosis of trophoblast type is a distinct pathologic feature in late pregnancy, and it is associated with lower placental weight. New classification of decidual vasculopathy helps with better stratification and categorization of placental maternal vascular abnormalities of late pregnancy.

Endocan, a Soluble Marker of Endothelial Cell Activation Is a Molecular Marker of Disease Severity in Women with Preeclampsia. Reprod Sci 2022; 29:2310-2321. [PMID: 35118598 DOI: 10.1007/s43032-022-00858-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 01/15/2022] [Indexed: 12/31/2022]
Abstract
Endocan is a proteoglycan secreted by activated endothelium that regulates angiogenesis via interaction with hepatocyte growth factor (HGF). We hypothesized that women diagnosed with preeclampsia (PE) and/or fetal growth restriction (FGR) have elevated circulating endocan concentrations in direct relationship with severity of clinical manifestations. Serum concentration of endocan and HGF were analyzed in 224 women grouped as healthy pregnant controls (P-CRL, n = 77), PE with severe features (sPE, n = 83), chronic hypertension (crHTN: n = 36), idiopathic FGR (n = 18), and healthy non-pregnant controls (NP-CRL, n = 7). Endocan and HGF measured by immunoassay were analyzed along with markers of inflammation, angiogenesis, and protein misfolding (urine congophilia). Endocan expression in the placenta and/or myometrium was studied by immunohistochemistry and real-time PCR. Compared to gestational age-matched P-CRL, women with early-onset sPE had higher circulating endocan concentrations. Among women with PE and/or FGR, endocan concentration correlated with soluble endoglin and urine congophilia but not with HGF or markers of inflammation or angiogenesis. In the placenta, endocan was expressed in villous and extravillous trophoblasts and endothelium. Intense endocan immunostaining was observed in plaque-like aggregations of sPE placentas complicated with FGR. In addition, thickened blood vessels in the myometrium of sPE patients stained positive for endocan. Women with early-onset sPE have elevated serum endocan likely reflecting chronic endothelial activation. Enhanced expression and/or deposition of endocan at the sites of placental injury and in remodeled maternal blood vessels supports a role for endocan in either vascular rescue or as a contributor to FGR and perhaps long-term cardiovascular morbidity.
