Association between maternal and perinatal outcomes and histological changes in the placenta of patients with Covid-19: A cohort study. Medicine (Baltimore) 2024; 103:e38171. [PMID: 38788031 PMCID: PMC11124646 DOI: 10.1097/md.0000000000038171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 04/17/2024] [Indexed: 05/26/2024] Open
Abstract
Although studies evaluated placental involvement in Covid-19 patients, few have assessed its association with clinical repercussions. The study aimed to determine the association between the clinical status and maternal and perinatal outcomes of patients with Covid-19 at delivery and changes in placental histology. It is so far the largest cohort evaluating placentas of patients infected by the SARS-CoV-2. A secondary analysis was conducted of a database from which a cohort of 226 patients, who tested real-time polymerase chain reaction-positive for Covid-19 at delivery and whose placentas were collected and submitted to pathology, was selected for inclusion. One or more types of histological changes were detected in 44.7% of the 226 placentas evaluated. The most common abnormalities were maternal vascular malperfusion (38%), evidence of inflammation/infection (9.3%), fetal vascular malperfusion (0.8%), fibrinoid changes and intervillous thrombi (0.4%). Oxygen use (P = .01) and need for admission to an intensive care unit (ICU) (P = .04) were less common in patients with placental findings, and hospital stay was shorter in these patients (P = .04). There were more fetal deaths among patients with evidence of inflammation/infection (P = .02). Fetal death, albeit uncommon, is associated with findings of inflammation/infection. Oxygen use and need for admission to an ICU were less common among patients with placental findings, probably due to the pregnancy being interrupted early. None of the other findings was associated with maternal clinical status or with adverse perinatal outcome.

Abstract
Accurate placenta pathology assessment is essential for managing maternal and newborn health, but the placenta's heterogeneity and temporal variability pose challenges for histology analysis. To address this issue, we developed the 'Histology Analysis Pipeline.PY' (HAPPY), a deep learning hierarchical method for quantifying the variability of cells and micro-anatomical tissue structures across placenta histology whole slide images. HAPPY differs from patch-based features or segmentation approaches by following an interpretable biological hierarchy, representing cells and cellular communities within tissues at a single-cell resolution across whole slide images. We present a set of quantitative metrics from healthy term placentas as a baseline for future assessments of placenta health and we show how these metrics deviate in placentas with clinically significant placental infarction. HAPPY's cell and tissue predictions closely replicate those from independent clinical experts and placental biology literature.

Abstract
Background No study has been conducted to specifically demonstrate the relationship between gestational diabetes mellitus (GDM) status, inflammatory factors, and postnatal umbilical coiling index (pUCI). Understanding this relationship could help select the best interventions to save the fetus. To evaluate the effects of maternal venous and umbilical cord blood levels of high sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-alpha (TNF-alpha) on pUCI in GDM and non-GDM groups. Methods This prospective observational study included 40 participants in each of the GDM and non-GDM groups, matched for maternal age, ethnicity, and parity. The GDM diagnosis was confirmed by 24 to 28 weeks of gestation (WOG) and a 2-step strategy. The covariates of interest were maternal hs-CRP and TNF-α, measured at 37 to 40 WOG, and their UC analogous was measured during delivery. The gross morphologies were assessed immediately after delivery. The UC coiling was quantitatively assessed by the pUCI. To compare the GDM and non-GDM groups, the t test and the Mann-Whitney test were used for normal and non-normal variables, respectively. Results There was not a significant difference in hs-CRP and TNF-a levels in maternal venous blood or UC blood between the GDM and non-GDM groups. The mean (SD) of pUCI in the GDM and non-GDM groups were 0.28 (0.15) and 0.24 (0.21) (P = 0.441), respectively. In the GDM group, none of the 4 covariates of interest had significant effects on the UCI. Among the non-GDM participants, merely the UC hs-CRP had a direct association with the pUCI, with a Pearson correlation of 0.54 (P = 0.001). Impacts of hs-CRP and TNF-α on the pUCI were assessed using Poisson regression models and no significant findings were detected (95% CI, 0.999-1.001, for all parameters). Conclusion In the GDM group, no apparent association was observed between inflammatory factors and pUCI, although a direct association was detected between UC hs-CRP and pUCI in the non-GDM.

Placenta 2023; 133:32-39. [PMID: 36791493 DOI: 10.1016/j.placenta.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 01/27/2023] [Accepted: 02/03/2023] [Indexed: 02/08/2023]
Abstract
INTRODUCTION Villitis of unknown etiology (VUE), chronic chorioamnionitis (CC), chronic deciduitis (CD) and chronic histiocytic intervillositis (CHI) are most likely the result of a pathologic immune reaction caused by maternal anti-fetal rejection. We analyzed placentas of twin pregnancies with manifestation of these lesions in monozygotic and dizygotic instances. METHODS Twin pregnancies from our archive with at least one chronic inflammatory lesion were selected for further analysis and assessed concerning zygosity (gender, chorionicity, short tandem repeat (STR)-analysis). RESULTS The cohort comprised sixteen twin placentas, monozygotic in five cases and dizygotic in 11 cases, respectively. VUE (n = 4), CC (n = 1) and CHI (n = 3) manifested concordantly in both placentas of the monozygotic pregnancies and affected discordantly one of the twin placentas in the dizygotic instances. CD (n = 10) manifested concordantly in two and discordantly in one of the monozygotic placentas, and concordantly in three and discordantly in four of the dizygotic instances. Intrauterine fetal demise (n = 3), preterm birth (n = 9) and low birth weight (n = 2) were recognized. Discordant fetal growth in live born children was recognized in two dizygotic cases with discordant manifestation of VUE and CHI. DISCUSSION The concordant manifestation of VUE, CC and CHI in monozygotic and the discordant pattern of inflammation in dizygotic pregnancies points to pathologic immune mechanisms against genetically determined fetal antigens being essential for the development of these entities. The heterogenous manifestation of CD could be a hint for diverse fetal or maternal etiologic factors that may contribute to this lesion.

Abstract
Pathologic examination of the placenta can provide insight into likely (and unlikely) causes of antepartum and intrapartum events, diagnoses with urgent clinical relevance, prognostic information for mother and infant, support for practice evaluation and improvement, and insight into advancing the sciences of obstetrics and neonatology. Although it is true that not all placentas require pathologic examination (although alternative opinions have been expressed), prioritization of placentas for pathologic examination should be based on vetted indications such as maternal comorbidities or pregnancy complications in which placental pathology is thought to be useful for maternal or infant care, understanding pathophysiology, or practice modifications. Herein we provide placental triage criteria for the obstetrical and neonatal provider based on publications and expert opinion of 16 placental pathologists and a pathologists' assistant, formulated using a modified Delphi approach. These criteria include indications in which placental pathology has clinical relevance, such as pregnancy loss, maternal infection, suspected abruption, fetal growth restriction, preterm birth, nonreassuring fetal heart testing requiring urgent delivery, preeclampsia with severe features, or neonates with early evidence of multiorgan system failure including neurologic compromise. We encourage a focused gross examination by the provider or an attendant at delivery for all placentas and provide guidance for this examination. We recommend that any placenta that is abnormal on gross examination undergo a complete pathology examination. In addition, we suggest practice criteria for placental pathology services, including a list of critical values to be used by the relevant provider. We hope that these sets of triage indications, criteria, and practice suggestions will facilitate appropriate submission of placentas for pathologic examination and improve its relevance to clinical care.

[PMID: 36252320 DOI: 10.1016/j.placenta.2022.09.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 08/29/2022] [Accepted: 09/13/2022] [Indexed: 12/14/2022]
Abstract
INTRODUCTION The purpose of this study was to determine the association between the postnatal umbilical coiling index (pUCI) and vascular endothelial growth factor A (VEGFA) and its receptor (VEGFR2) in parturients with and without gestational diabetes mellitus (GDM). METHODS Within 24 h following birth, the umbilical cord and pUCI of 29 newborns with GDM and 28 neonates with non-GDM parturients were prospectively examined. Real-time PCR tests were used to determine the expression levels of the VEGFA and VEGFR2 genes, measured from the umbilical cord. The Mann-Whitney and Chi-squared tests were used to compare continuous and discrete variables with and without GDM. RESULTS The median (IQR) of maternal age was 30 (26-34) years. There were no differences in demographic features between GDM and non-GDM parturients. While there was a marginal difference in VEGFA expression levels between the GDM and non-GDM groups (P-values = 0.07), no difference was detected for VEGFR2 (P-values = 0.75). Comparing hyper- and hypocoiling cords revealed a small difference in VEGFA levels (P-values = 0.05), but no change in VEGFR2 (P-values = 0.50). Furthermore, in both GDM and non-GDM parturients, down-regulated VEGFA was the general rule among abnormal pUCIs. DISCUSSION The GDM and coiling state both are associated with the amount of VEGFA expression, but neither is related to VEGFR2. Furthermore, regardless of whether the patient has GDM or not, the abnormal coiling pattern appears to be related to the VEGFA down-regulation.

Abstract
Background: Chronic deciduitis is a chronic inflammatory placental disease. It is associated with severe perinatal complications, especially recurrent miscarriage, preterm birth, preterm labor, and preterm prelabor rupture of membranes.Methods: This study presents a detailed quantification of plasma cells and lymphocytes, and regards clinicopathological associations concerning different trimesters in 99 cases displaying chronic deciduitis with plasma cells (CD), 23 cases from the second trimester and 76 cases from the third trimester, respectively. The control group without CD consisted of matched placentas concerning the gestational weeks.Results: In every instance lymphocytes were more numerous than plasma cells. The mean value/highest score in ten high power fields were 50/321 for plasma cells, and 460/995 for lymphocytes, respectively. In the second trimester the scores for plasma cells were significantly higher than in the third trimester. In the third trimester preterm labor occurred significantly more often in cases with chronic deciduitis related to the control group (P < .05).Conclusion: In chronic deciduitis the plasma cell count is usually higher in the second compared to the third trimester. A brisk infiltration of the decidua with plasma cells could probably point to a more severe clinical manifestation and a higher risk for preterm labor and preterm birth.

Epigenetic Dysregulation of Trophoblastic Gene Expression in Gestational Trophoblastic Disease. Biomedicines 2021; 9:biomedicines9121935.

Abstract
Gestational trophoblastic diseases (GTDs) have not been investigated for their epigenetic marks and consequent transcriptomic changes. Here, we analyzed genome-wide DNA methylation and transcriptome data to reveal the epigenetic basis of disease pathways that may lead to benign or malignant GTDs. RNA-Seq, mRNA microarray, and Human Methylation 450 BeadChip data from complete moles and choriocarcinoma cells were bioinformatically analyzed. Paraffin-embedded tissues from complete moles and control placentas were used for tissue microarray construction, DNMT3B immunostaining and immunoscoring. We found that DNA methylation increases with disease severity in GTDs. Differentially expressed genes are mainly upregulated in moles while predominantly downregulated in choriocarcinoma. DNA methylation principally influences the gene expression of villous trophoblast differentiation-related or predominantly placenta-expressed genes in moles and choriocarcinoma cells. Affected genes in these subsets shared focal adhesion and actin cytoskeleton pathways in moles and choriocarcinoma. In moles, cell cycle and differentiation regulatory pathways, essential for trophoblast/placental development, were enriched. In choriocarcinoma cells, hormone biosynthetic, extracellular matrix-related, hypoxic gene regulatory, and differentiation-related signaling pathways were enriched. In moles, we found slight upregulation of DNMT3B protein, a developmentally important de novo DNA methylase, which is strongly overexpressed in choriocarcinoma cells that may partly be responsible for the large DNA methylation differences. Our findings provide new insights into the shared and disparate molecular pathways of disease in GTDs and may help in designing new diagnostic and therapeutic tools.

Abstract
Africa has the highest number of pregnant women with human immunodeficiency virus (HIV). In some studies, HIV has been associated with adverse perinatal outcomes. However, the pathophysiological mechanism leading to adverse fetal outcomes is not known. Maternal vascular malformation, chorioamnionitis, and decreased placental weight have been described as placental features associated with HIV in some studies. The use of antiretroviral therapy has reduced perinatal transmission of HIV and adverse fetal outcomes. However, placental mechanisms associated with HIV and the fetal immune response to maternal HIV infection are poorly understood. Additional research is required to understand whether altered maternal immunity in women living with HIV can trigger fetal responses leading to stillbirth or preterm birth.

Hypertensive disease, preterm birth, fetal growth restriction and chronic inflammatory disorders of the placenta: experiences in a single institution with a standardized protocol of investigation. Arch Gynecol Obstet 2021; 306:337-347. [PMID: 34693459 DOI: 10.1007/s00404-021-06293-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Accepted: 10/13/2021] [Indexed: 11/30/2022]
Abstract
PURPOSE Chronic inflammatory disorders of the placenta, in particular villitis of unknown etiology (VUE), chronic deciduitis (CD), chronic chorioamnionitis (CC), chronic histiocytic intervillositis (CHI), and eosinophilic/T-cell chorionic vasculitis (ETCV) can exclusively be diagnosed histologically. Using a standardized procedure for submission and pathological-anatomical examination of placentas in a single perinatal care center, we analyzed the association of chronic placental lesions to perinatal complications. METHODS We reviewed all singleton placentas and miscarriages that were examined histologically over a period of ten years after having implemented a standardized protocol for placental submission in our hospital. Cases with chronic inflammatory lesions were identified, and clinical data were analyzed and compared with a focus on preterm birth, hypertensive disorders, and fetal growth restriction and/or fetal demise. RESULTS In 174 placentas, at least one of the chronic inflammatory entities was diagnosed. CD was the most frequent disorder (n = 95), and had strong associations with preterm birth (47.3% of all cases with CD) and intrauterine fetal demise. VUE (n = 74) was exclusively diagnosed in the third trimester. This disorder was associated with a birth weight below the 10th percentile (45% of the cases) and hypertensive disease in pregnancy. Miscarriage and intrauterine fetal demise were associated with CHI (in 66.7% of cases, n = 18). CONCLUSIONS Chronic inflammatory disorders are frequently observed and contribute to major obstetric and perinatal complications. Further studies are needed to get a better picture of the connection between adverse obstetric outcomes and chronic inflammation to aid in the better counseling of patients.

Abstract
INTRODUCTION Placental Protein 1 (PP1), PP8, and PP22 were isolated from the placenta. Herein, we aimed to identify PP1, PP8, and PP22 proteins and their placental and trophoblastic expression patterns to reveal potential involvement in pregnancy complications. METHODS We analyzed PP1, PP8, and PP22 proteins with LC-MS. We compared the placental behaviors of PP1, PP8, and PP22 to the predominantly placenta-expressed PP5/TFPI-2. Placenta-specificity scores were generated from microarray data. Trophoblasts were isolated from healthy placentas and differentiated; total RNA was isolated and subjected to microarray analysis. We assigned the placentas to the following groups: preterm controls, early-onset preeclampsia, early-onset preeclampsia with HELLP syndrome, term controls, and late-onset preeclampsia. After histopathologic examination, placentas were used for tissue microarray construction, immunostaining with anti-PP1, anti-PP5, anti-PP8, or anti-PP22 antibodies, and immunoscoring. RESULTS PP1, PP8, and PP22 were identified as 'nicotinate-nucleotide pyrophosphorylase', 'serpin B6', and 'protein disulfide-isomerase', respectively. Genes encoding PP1, PP8, and PP22 are not predominantly placenta-expressed, in contrast with PP5. PP1, PP8, and PP22 mRNA expression levels did not increase during trophoblast differentiation, in contrast with PP5. PP1, PP8, and PP22 immunostaining were detected primarily in trophoblasts, while PP5 expression was restricted to the syncytiotrophoblast. The PP1 immunoscore was higher in late-onset preeclampsia, while the PP5 immunoscore was higher in early-onset preeclampsia. DISCUSSION PP1, PP8, and PP22 are expressed primarily in trophoblasts but do not have trophoblast-specific regulation or functions. The distinct dysregulation of PP1 and PP5 expression in either late-onset or early-onset preeclampsia reflects different pathophysiological pathways in these preeclampsia subsets.

Abstract
INTRODUCTION The objective of this study was to compare the histomorphological changes of placenta and umbilical cord (UC), between gestational diabetes mellitus (GDM) and non- GDM pregnancies. METHODS In this prospective study, 222 parturients were recruited (117 GDM and 105 non-GDM). GDM was confirmed at 24-28 weeks of gestation, using one-step strategy. A full record of demographic, laboratory, histologic and gross morphology data of placenta and UC was extracted and analyzed. RESULTS Overall, 222 placentas/UCs met inclusion criteria. The mean (SD) of gestational age of GDM diagnosis was 20.68 (10.02) and the GDM duration was 16.76 (8.98) weeks. The mean HbA1C was 6.03 (0.41) % in the GDM group. The gross morphology findings including UC diameter and thick edematous UC differed significantly between two groups and more presented in GDM group, 1.41 (0.03) vs. 1.28 (0.03) centimeters; p-value = 0.006 and 34.19% vs. 16.19%; p-value = 0.002, respectively. The umbilical coiling index (UCI) was similar in two groups (p-value = 0.61). In the histological evaluation, persistence of central vessels differed significantly between two groups, more detected in non-GDM (47.62% vs. 32.97%; p-value = 0.04). No other significant histomorphological changes were detected between two groups. DISCUSSION This study showed that gross morphologic features such as UC diameter increment and thick edematous UC happened more frequently, among the GDM parturients. Due to early diagnosis, diagnosis strategy, and optimal glycemic control, the histomorphological changes were less in GDM comparing of non-GDM group.

We analyzed high-dimensional RNA and protein data to characterize molecular features of complete hydatidiform moles (CHMs) and corresponding pathologic pathways. CHMs and first trimester placentas were collected, histopathologically examined, then flash-frozen or paraffin-embedded. Frozen CHMs and control placentas were subjected to RNA-Seq, with resulting data and published placental RNA-Seq data subjected to bioinformatics analyses. Paraffin-embedded tissues from CHMs and control placentas were used for tissue microarray (TMA) construction, immunohistochemistry, and immunoscoring for galectin-14. Of the 14,022 protein-coding genes expressed in all samples, 3,729 were differentially expressed (DE) in CHMs, of which 72% were up-regulated. DE genes were enriched in placenta-specific genes (OR = 1.88, p = 0.0001), of which 79% were down-regulated, imprinted genes (OR = 2.38, p = 1.54 × 10-6), and immune genes (OR = 1.82, p = 7.34 × 10-18), of which 73% were up-regulated. DNA methylation-related enzymes and histone demethylases were dysregulated. "Cytokine-cytokine receptor interaction" was the most impacted of 38 dysregulated pathways, among which 17 were immune-related pathways. TMA-based immunoscoring validated the lower expression of galectin-14 in CHM. In conclusion, placental functions were down-regulated, imprinted gene expression was altered, and immune pathways were activated, indicating complex dysregulation of placental developmental and immune processes in CHMs.

Automated segmentation of villi in histopathology images of placenta. Comput Biol Med 2019; 113:103420. [PMID: 31514041 DOI: 10.1016/j.compbiomed.2019.103420] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 08/12/2019] [Accepted: 08/27/2019] [Indexed: 12/17/2022]
Abstract
PURPOSE Manual analysis of clinical placenta pathology samples under the microscope is a costly and time-consuming task. Computer-aided diagnosis might offer a means to obtain fast and reliable results and also substantially reduce inter- and intra-rater variability. Here, we present a fully automated segmentation method that is capable of distinguishing the complex histological features of the human placenta (i.e., the chorionic villous structures). METHODS The proposed pipeline consists of multiple steps to segment individual placental villi structures in hematoxylin and eosin (H&E) stained placental images. Artifacts and undesired objects in the histological field of view are detected and excluded from further analysis. One of the challenges in our new algorithm is the detection and segmentation of touching villi in our dataset. The proposed algorithm uses the top-hat transformation to detect candidate concavities in each structure, which might represent two distinct villous structures in close proximity. The detected concavities are classified by extracting multiple features from each candidate concavity. Our proposed pipeline is evaluated against manual segmentations, confirmed by an expert pathologist, on 12 scans from three healthy control patients and nine patients diagnosed with preeclampsia, containing nearly 5000 individual villi. The results of our method are compared to a previously published method for villi segmentation. RESULTS Our algorithm detected placental villous structures with an F1 score of 80.76% and sensitivity of 82.18%. These values are substantially better than the previously published method, whose F1 score and sensitivity are 65.30% and 55.12%, respectively. CONCLUSION Our method is capable of distinguishing the complex histological features of the human placenta (i.e., the chorionic villous structures), removing artifacts over a large histopathology sample of human placenta, and (importantly) account for touching adjacent villi structures. Compared to existing methods, our developed method yielded high accuracy in detecting villi in placental images.

Abstract
Background More than 50 human placental proteins were isolated and physico-chemically characterized in the 70–80s by Hans Bohn and co-workers. Many of these proteins turned to have important role in placental functions and diagnostic significance in pregnancy complications. Among these proteins was membrane-associated placental protein 4 (MP4), for which identity or function has not been identified yet. Our aim was to analyze the sequence and placental expression of this protein in normal and complicated pregnancies including miscarriage, preeclampsia and HELLP syndrome. Methods Lyophilized MP4 protein and frozen healthy placental tissue were analyzed using HPLC-MS/MS. Placental tissue samples were obtained from women with elective termination of pregnancy (first trimester controls, n = 31), early pregnancy loss (EPL) (n = 13), early preeclampsia without HELLP syndrome (n = 7) and with HELLP syndrome (n = 8), late preeclampsia (n = 8), third trimester early controls (n = 5) and third trimester late controls (n = 9). Tissue microarrays were constructed from paraffin-embedded placentas (n = 81). Slides were immunostained with monoclonal perlecan antibody and evaluated using light microscopy and virtual microscopy. Perlecan was also analyzed for its expression in placentas from normal pregnancies using microarray data. Results Mass spectrometry-based proteomics of MP4 resulted in the identification of basement membrane-specific heparan sulfate proteoglycan core protein also known as perlecan. Immunohistochemistry showed cytoplasmic perlecan localization in syncytiotrophoblast and cytotrophoblasts of the villi. Perlecan immunoscore decreased with gestational age in the placenta. Perlecan immunoscores were higher in EPL compared to controls. Perlecan immunoscores were higher in early preeclampsia without and with HELLP syndrome and lower in late preeclampsia than in respective controls. Among patients with preeclampsia, placental perlecan expression positively correlated with maternal vascular malperfusion and negatively correlated with placental weight. Conclusion Our findings suggest that an increased placental perlecan expression may be associated with hypoxic ischaemic injury of the placenta in miscarriages and in early preeclampsia with or without HELLP syndrome.

Placental Galectins Are Key Players in Regulating the Maternal Adaptive Immune Response. Front Immunol 2019; 10:1240. [PMID: 31275299 PMCID: PMC6593412 DOI: 10.3389/fimmu.2019.01240] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Accepted: 05/16/2019] [Indexed: 12/12/2022] Open
Abstract
Galectins are potent immunomodulators that regulate maternal immune responses in pregnancy and prevent the rejection of the semi-allogeneic fetus that also occurs in miscarriages. We previously identified a gene cluster on Chromosome 19 that expresses a subfamily of galectins, including galectin-13 (Gal-13) and galectin-14 (Gal-14), which emerged in anthropoid primates. These galectins are expressed only by the placenta and induce the apoptosis of activated T lymphocytes, possibly contributing to a shifted maternal immune balance in pregnancy. The placental expression of Gal-13 and Gal-14 is decreased in preeclampsia, a life-threatening obstetrical syndrome partly attributed to maternal anti-fetal rejection. This study is aimed at revealing the effects of Gal-13 and Gal-14 on T cell functions and comparing the expression of these galectins in placentas from healthy pregnancies and miscarriages. First-trimester placentas were collected from miscarriages and elective termination of pregnancies, tissue microarrays were constructed, and then the expression of Gal-13 and Gal-14 was analyzed by immunohistochemistry and immunoscoring. Recombinant Gal-13 and Gal-14 were expressed and purified, and their effects were investigated on primary peripheral blood T cells. The binding of Gal-13 and Gal-14 to T cells and the effects of these galectins on apoptosis, activation marker (CD25, CD71, CD95, HLA-DR) expression and cytokine (IL-1β, IL-6, IL-8, IL-10, IFNγ) production of T cells were examined by flow cytometry. Gal-13 and Gal-14 are primarily expressed by the syncytiotrophoblast at the maternal-fetal interface in the first trimester, and their placental expression is decreased in miscarriages compared to first-trimester controls. Recombinant Gal-13 and Gal-14 bind to T cells in a population- and activation-dependent manner. Gal-13 and Gal-14 induce apoptosis of Th and Tc cell populations, regardless of their activation status. Out of the investigated activation markers, Gal-14 decreases the cell surface expression of CD71, Gal-13 increases the expression of CD25, and both galectins increase the expression of CD95 on T cells. Non-activated T cells produce larger amounts of IL-8 in the presence of Gal-13 or Gal-14. In conclusion, these results show that Gal-13 and Gal-14 already provide an immunoprivileged environment at the maternal-fetal interface during early pregnancy, and their reduced expression is related to miscarriages.

Abstract
Objectives The objective of this study was to investigate the relationship between the postnatal umbilical coiling index (pUCI), and intrapartum and neonatal outcomes in parturients with gestational diabetes mellitus (GDM) and non-GDM. Methods An evaluation of the umbilical cords and pUCI of 117 neonates of GDM and 105 of non-GDM parturients were prospectively studied within 24 h after delivery. Furthermore, obstetric history, intrapartum and neonatal data were recorded. Results Premature rupture of membrane (PROM) (p = 0.001), emergency cesarean delivery (p = 0.01), spontaneous preterm delivery (p = 0.006), duration of hospital admission (p < 0.001), and congenital malformations (p = 0.03) were significantly higher in the GDM group. Moreover, pUCI had a significant association with large for gestational age (LGA) (p = 0.009), and meconium-stained amniotic fluid (p = 0.04) in the GDM group. In addition, increment of pUCI had significant association with spontaneous preterm delivery in both groups (p = 0.002) (OR = 1.23). Conclusions GDM is associated with spontaneous preterm delivery, PROM, emergency cesarean delivery, duration of hospital admission, and congenital malformations. Increase in pUCI could increase the rate of spontaneous preterm delivery in normal pregnancy and pregnancy complicated by GDM, as well as, the rate of LGA and meconium-stained amniotic fluid in GDM.

Abstract
Malaria during pregnancy results in intrauterine growth restriction, fetal anemia, and infant mortality. Women are more susceptible to malaria during pregnancy due to malaria‐induced inflammation and the sequestration of infected red blood cells in the placenta, which bind to the chondroitin sulfate portion of syndecan‐1 on the syncytiotrophoblast and in the intervillous space. Syndecan‐1 is a dimeric proteoglycan with an extracellular ectodomain that is cleaved from the transmembrane domain (referred to as “shedding”) by matrix metalloproteinases (MMPs), likely the secreted MMP‐9. The ectodomain includes four binding sites for chondroitin sulfate, which are proximal to the transmembrane domain, and six distal binding sites primarily for heparan sulfate. This “shedding” of syndecan‐1 is inhibited by the presence of the heparan sulfate chains, which can be removed by heparanase. The intervillous space contains fibrin strands and syndecan‐1 ectodomains free of heparan sulfate. The following is proposed as the sequence of events that leads to and is primarily responsible for sequestration in the intervillous space of the placenta. Inflammation associated with malaria triggers increased heparanase activity that degrades the heparan sulfate on the membrane‐bound syndecan‐1. Inflammation also upregulates MMP‐9 and the removal of heparan sulfate gives MMP‐9 access to cleave syndecan‐1, thereby releasing dimeric syndecan‐1 ectodomains with at least four chondroitin sulfate chains attached. These multivalent ectodomains bind infected RBCs together leading to their aggregation and entrapment in intervillous fibrin. This mechanism suggests possible new targets for anti‐placental malaria drugs such as the inhibition of MMP‐9. Doxycycline is an antimalarial drug which inhibits MMP‐9.

Abstract
INTRODUCTION Placental Protein 5 (PP5)/Tissue Factor Pathway Inhibitor-2 (TFPI-2) is an extracellular matrix-associated protein mainly expressed by the syncytiotrophoblast that may regulate trophoblast invasion. Our aim was to study placental PP5/TFPI-2 expression and its relation to placental pathology in various forms of preeclampsia and HELLP syndrome. METHODS Placental and maternal blood specimens were collected at the time of delivery from the same women in the following groups: 1) early controls; 2) early preeclampsia; 3) early preeclampsia with HELLP syndrome; 4) late controls; and 5) late preeclampsia. After histopathological examination, placental specimens were immunostained with polyclonal anti-PP5/TFPI-2 antibody on Western blot and tissue microarray immunohistochemistry. Placental PP5/TFPI-2 immunoscores were assessed manually and with a semi-automated method. Maternal sera were immunoassayed for PP5/TFPI-2. RESULTS PP5/TFPI-2 was localized to the cytoplasm of syncytiotrophoblast. Manual and semi-automated PP5/TFPI-2 immunoscores were higher in early preeclampsia with or without HELLP syndrome but not in late preeclampsia than in respective controls. In patients with preeclampsia, the correlation of placental PP5/TFPI-2 expression with maternal vascular malperfusion score of the placenta was positive while it was negative with birthweight and placental weight. Maternal serum PP5/TFPI-2 concentration was higher in early preeclampsia and it tended to be higher in early preeclampsia with HELLP syndrome than in early controls. DISCUSSION Our findings suggest that an increased placental PP5/TFPI-2 expression may be associated with abnormal placentation in early preeclampsia, with or without HELLP syndrome.

Abstract
Objective To determine the frequency and type of histopathologic lesions in placentas delivered by women with a normal pregnancy outcome. Methods This retrospective cohort study included placental samples from 944 women with a singleton gestation who delivered at term without obstetrical complications. Placental lesions were classified into the following four categories as defined by the Society for Pediatric Pathology and by our unit: (1) acute placental inflammation, (2) chronic placental inflammation, (3) maternal vascular malperfusion and (4) fetal vascular malperfusion. Results (1) Seventy-eight percent of the placentas had lesions consistent with inflammatory or vascular lesions; (2) acute inflammatory lesions were the most prevalent, observed in 42.3% of the placentas, but only 1.0% of the lesions were severe; (3) acute inflammatory lesions were more common in the placentas of women with labor than in those without labor; (4) chronic inflammatory lesions of the placenta were present in 29.9%; and (5) maternal and fetal vascular lesions of malperfusion were detected in 35.7% and 19.7%, respectively. Two or more lesions with maternal or fetal vascular features consistent with malperfusion (high-burden lesions) were present in 7.4% and 0.7%, respectively. Conclusion Most placentas had lesions consistent with inflammatory or vascular lesions, but severe and/or high-burden lesions were infrequent. Mild placental lesions may be interpreted either as acute changes associated with parturition or as representative of a subclinical pathological process (intra-amniotic infection or sterile intra-amniotic inflammation) that did not affect the clinical course of pregnancy.

Abstract
The placenta is one of the most exciting organs. It is dynamic; its morphology and function continuously develop and adjust over its brief life span. It mediates the physiology of two distinct yet highly interconnected individuals. The pathology that develops in the placenta, and the adaptations the placenta undergoes to mitigate this pathology, may influence the later life health of the mother and baby (Circ Res, 116, 2015, 715; Hum Reprod Update, 17, 2011, 397; Nutr Rev 71, 2013, S88; Placenta, 36, 2015, S20). Pathological placenta examination may reveal macroscopic and microscopic patterns that provide valuable information to the obstetricians, neonatologists, and pediatricians caring for the family. The placenta often plays a key role in understanding adverse fetal outcomes such as hypoxic brain injury, cerebral palsy, fetal growth restriction, stillbirth, and neonatal death (Placenta, 35, 2014, 552; Placenta, 52, 2017, 58; Placenta, 30, 2009, 700; Obstet Gynecol, 114, 2009, 809; Clin Perinatol, 33, 2006, 503; Pediatr Dev Pathol, 11, 2008, 456; Arch Pathol Lab Med, 124, 2000, 1785). Moreover, it may help to understand the pathophysiology of pregnancy, improve management of subsequent pregnancies, and assist in medicolegal assessment. Placental pathologic examination may even provide evidence of susceptibility to adult-onset diseases such as diabetes (Pediatr Dev Pathol, 6, 2003, 54; Diabetes Metab, 36, 2010, 682; BJOG, 113, 2006, 1126; Int J Gynaecol Obstet, 104, 2009, S25; Zentralbl Gynakol, 97, 1975, 875). Pathologic examination of the placenta may thus be of tremendous value, particularly for those women experiencing an adverse pregnancy outcome. However, this potential utility may be entirely wasted, if the findings are not communicated in an effective manner to the appropriate clinicians. An optimized, readily understandable report of pathological findings is essential for clinical utility.

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.

Abstract
Background: Pregnancy-induced hypertension adversely affects the development of placenta and growth of fetus. The objective of the study was to compare the weight and volume of placentae in normotensive pregnancies versus patients with pregnancy-induced hypertension. Material & Methods: This comparative cross-sectional study was conducted in the Department of Anatomy, Gomal Medical College, D.I.Khan, from January 2014 to October 2014. Sample size was 150. Consecutive sampling technique was used. Inclusion criteria was pregnant women of all ages and parity. Grouping variable was presence of PIH with two attributes of yes and no. Research variables were placental weight in grams and placental volume in milliliters. A total of 150 placentae with the cord were collected after delivery from pregnant women, from the labour room of obstetric unit, DHQ Teaching Hospital, D.I.Khan. Structured proforma was used to record the presence or otherwise of PIH. Subjects were divided into two groups on basis of presence or absence of PIH; group A with 50 normotensive pregnant females and group B with 100 patients with PIH. Placental weight and volume were measured in terms of mean ± SD, whereas categorical variables as frequency and percentage. Students t test was used in Social Sciences Online calculator. Results: Out of 150 patients, 50 were normotensive and 100 were having PIH. Mean weight of placentae in groups A and B were 421.40±17.90 g and 320.60 ±14.95 g respectively whereas mean volume of placentae in groups A and B were 396.10±10.40 ml and 280.50 ±10.35 ml respectively.

Human placentophagy: a review. Am J Obstet Gynecol 2018; 218:401.e1-401.e11.

Abstract
Placentophagy or placentophagia, the postpartum ingestion of the placenta, is widespread among mammals; however, no contemporary human culture incorporates eating placenta postpartum as part of its traditions. At present, there is an increasing interest in placentophagy among postpartum women, especially in the United States. The placenta can be eaten raw, cooked, roasted, dehydrated, or encapsulated or through smoothies and tinctures. The most frequently used preparation appears to be placenta encapsulation after steaming and dehydration. Numerous companies offer to prepare the placenta for consumption, although the evidence for positive effects of human placentophagy is anecdotal and limited to self-reported surveys. Without any scientific evidence, individuals promoting placentophagy, especially in the form of placenta encapsulation, claim that it is associated with certain physical and psychosocial benefits. We found that there is no scientific evidence of any clinical benefit of placentophagy among humans, and no placental nutrients and hormones are retained in sufficient amounts after placenta encapsulation to be potentially helpful to the mother postpartum. In contrast to the belief of clinical benefits associated with human placentophagy, the Centers for Disease Control and Prevention recently issued a warning due to a case in which a newborn infant developed recurrent neonatal group B Streptococcus sepsis after the mother ingested contaminated placenta capsules containing Streptococcus agalactiae. The Centers for Disease Control and Prevention recommended that the intake of placenta capsules should be avoided owing to inadequate eradication of infectious pathogens during the encapsulation process. Therefore, in response to a woman who expresses an interest in placentophagy, physicians should inform her about the reported risks and the absence of clinical benefits associated with the ingestion. In addition, clinicians should inquire regarding a history of placenta ingestion in cases of postpartum maternal or neonatal infections such as group B Streptococcus sepsis. In conclusion, there is no professional responsibility on clinicians to offer placentophagy to pregnant women. Moreover, because placentophagy is potentially harmful with no documented benefit, counseling women should be directive: physicians should discourage this practice. Health care organizations should develop clear clinical guidelines to implement a scientific and professional approach to human placentophagy.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2018; 37:471-478. [PMID: 28850682 DOI: 10.1002/jum.14357] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Revised: 05/16/2017] [Accepted: 05/17/2017] [Indexed: 06/07/2023]
Abstract
OBJECTIVES To evaluate perinatal outcomes in singleton and twin pregnancies with pathologically confirmed velamentous cord insertion without vasa previa. METHODS This retrospective case-control study included all nonanomalous singleton and twin pregnancies with pathologically confirmed velamentous cord insertion delivered in a single institution between January 1, 2005, and July 1, 2015, and having an ultrasound examination by maternal-fetal medicine. For each case, the next 2 consecutive deliveries matched for gestational age at delivery ± 1 week and, in twins, amnionicity and chorionicity served as controls. Primary outcomes included surgical delivery for a nonreassuring intrapartum fetal heart rate tracing, umbilical arterial cord pH of less than 7.2, 5-minute Apgar score of less than 7, birth weight below the 10th percentile, neonatal intensive care unit admission, fetal or neonatal death, and cord avulsion necessitating manual placental extraction. RESULTS Outcomes were available for 53 singletons with 103 matched controls and 33 twin pregnancies with 65 matched controls. In singletons, velamentous cord insertion was associated with cord pH of less than 7.2 (odds ratio [OR] 3.5; 95% confidence interval [CI], 1.1-11.2; P = .039), 5-minute Apgar score of less than 7 (OR, 5.3; 95% CI, 0.99-28.1; P = .045), and cord avulsion requiring manual placental extraction (7.5% versus 0%; P = .012). Associations were suggested with increased surgical delivery for a nonreassuring intrapartum fetal heart rate tracing (OR, 2.4; 95% CI, 0.9-6.9; P = .14), birth weight below the 10th percentile (OR, 2.1; 95% CI, 0.8-5.9; P = .21), and fetal or neonatal death (3.8% versus 0%; P = .11). Velamentous cord insertions were also associated with placental abruption in singletons (7.5% versus 0%; P = .013). Among twins, velamentous cord insertion was associated with fetal or neonatal death (9.1% versus 0%; P = .036). CONCLUSIONS Isolated confirmed velamentous cord insertion is associated with adverse perinatal outcomes in singleton and twin gestations.

Abstract
Decidual vasculopathy (DV) is a general term for a number of lesions involving uteroplacental vessels. It is often seen in preeclamptic placentas and indicates a disorder of uteroplacental malperfusion and is associated with placental ischemia and infarction. Although some have advocated submitting special sections in order to better document DV, it is unclear which placental sections have the highest yield in demonstrating these abnormal vessels. Seventy-six consecutive cases of decidual vasculopathy were identified and evaluated for location of DV, as well as presence of other lesions of ischemic change, infarcts, and retroplacental hematomas. Sections reviewed were the membrane roll (MR), full thickness (FT) sections of the placental disc, and sections specifically of the basal plate (BP). DV was found in the MR in 67.1% of cases, in FT sections in 32.9%, and in the BP in 25.0% of cases ( P value = .004). DV was exclusive to the MR in 53.9%, the FT in 14.5%, and the BP in 9.2%. DV was present in 2 locations in 19.7% and in all 3 locations in 2.6%. The presence of DV in any location (MR, FT, and BP) was associated with placental ischemic change but not specifically with infarcts or retroplacental hematomas. The specific location of DV showed no difference in the presence of placental lesions. Our findings indicate DV is often present in 1 location and is associated with lesions of malperfusion. It is recommended that when clinically indicated, additional sections are submitted to demonstrate decidual vasculopathy.

Abstract
This study aimed to determine the incidence and clinical outcomes for varying patterns of placental histological inflammation (consistent with fetal or maternal inflammatory response) in an unselected population of >1000 women with a singleton pregnancy resulting in live birth delivering at or near term. One thousand one hundred nineteen cases were studied in a blind, prospective, unselected study with placentas categorized into five histological subgroups reflecting underlying maternal or fetal inflammatory response. Clinical outcomes studied included interventional delivery, an Apgar score <7 at 1 min, neonatal acidosis (pH < 7.2) and admission to neonatal special care. One hundred eighty-eight placentas (17 %) showed histological evidence of acute inflammation: 64 with funisitis (with or without other inflammation; 6 %); 16 with extensive acute inflammation across the chorionic plate, free membranes and subchorionic fibrin (1 %); 28 with acute inflammation restricted to the chorionic plate (2 %); 12 with acute inflammation restricted to the free membranes (1 %) and 68 with acute inflammation restricted to the subchorionic fibrin (6 %). Features of extensive acute inflammation were significantly associated with increased rate of interventional delivery (assisted vaginal delivery or emergency caesarean section; P < 0.01). The presence of funisitis was significantly associated with interventional delivery and other adverse outcomes including an Apgar score <7 at 1 min, clinical evidence of sepsis and admission to the neonatal intensive care unit (P < 0.05 for all). The data represent a quantitative rather than purely qualitative analysis of the contribution of histological lesions related to inflammation on short-term adverse neonatal outcomes and interventional delivery. Funisitis and extensive inflammation are associated with adverse clinical outcomes, but the precise mechanism underlying these remains to be elucidated.

Abstract
BACKGROUND Placenta previa (PP) is an obstetric complication that can affect maternal and fetal morbidity and mortality. Its prevalence is rising due to cesarean sections. There is no quantitative data of placenta in PP. In this study, quantitative parameters of placenta in cases with PP in comparison with normally implanted controls were investigated. METHODS In this quasi experimental study, placentas from pregnancies with PP and normally implanted controls (n = 10) were obtained from women who underwent cesarean section. Three full-thickness columns of each placenta were sampled using systematic uniform random sampling (SURS). Columns were cut into slices and slices were sectioned with 4 µm thickness. SURS selected sections were stained by Masson's trichrome. Stereological analysis was done on 8-10 SURS microscopic fields of each section. Absolute volume and volume density of chorionic villi, intervillous space, syncytiotrophoblast, fibrin and blood vessels in chorionic villi were estimated in both groups. Statistical analysis was done using Mann Whitney-U test and significant level was set at p < 0.05. RESULTS There was a significant reduction in total volume and volume density of fibrin deposits on the surface of chorionic villi (p < 0.05), and a significant increment in total volume and volume density of chorionic villous blood vessels in PP group in comparison with C group (p < 0.05). CONCLUSION Results showed that impairment in situation of implantation in PP can cause significant changes in the structure of placenta. These changes probably can be influential on the evolution and survival of fetus.

Abstract
OBJECTIVES: The overwhelming numbers of twins following assisted reproductive technology (ART) are dichorionic twins, but monochorionic twins account for around 0.9% of post ART pregnancies. The data for post ART-monochorionic pregnancy outcomes are scarce due to the rarity of this condition. Hence, we evaluated the obstetric outcomes of monochorionic and dichorionic pregnancies conceived on ART. SETTINGS: University teaching hospital. STUDY DESIGN: A case–control study of monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) pregnancies conceived following ART treatment. Charts of all women who conceived following ART from 2008 to 2013 were screened. Among them, the monochorionic twins diagnosed in the first trimester were included and their obstetric outcome was followed-up. For comparison, an equal number of dichorionic twin pregnancies from age and body mass index matched mothers was selected. RESULTS: The baseline clinical characteristics were similar between the two groups. MCDA group had a higher miscarriage rate (50%) than the DCDA group (10%), with three seconds trimester miscarriages in the MCDA group. The live birth rates were lower in the MCDA versus DCDA group (40% vs. 90%). Among triplet pregnancies with a monochorionic component, the live birth rate was only 25%. CONCLUSIONS: Monochorionic pregnancies following ART have poorer obstetric outcomes when compared to dichorionic pregnancies. For monochorionic pregnancies following ART, intensive antenatal surveillance at a tertiary level obstetric and neonatal center may help optimize the outcome.

Abstract
This study reports for the 1st time the incidence and interobserver variation of morphologic findings in a series of 34 term placentas from pregnancies with normal outcome used for perfusion studies. Histologic evaluation of placental tissue is challenging, especially when it comes to defining "normal tissue" versus "pathologic lesions." A scoring system for registration of abnormal morphologic findings was developed. Light microscopic examination was performed independently by 2 pathologists, and interobserver variation was analyzed. Findings in normal and perfused tissue were compared and selected findings were tested against success parameters from the perfusions. Finally, the criteria for frequent lesions with fair to poor interobserver variation in the nonperfused tissue were revised and reanalyzed. In the perfused tissue, the perfusion artefact "trophoblastic vacuolization," which is believed to represent dilated transtrophoblastic channels, was reproducible and significantly correlated to the perfusion marker "fetal leakage." In longer perfusions, microscopy of the perfused cotyledon revealed bacteria in the fetal vessels. This finding led to an adjustment in the perfusion protocol with addition of antibiotics to the medium. In the "normal" tissue, certain lesions were very frequent and showed only fair or poor interobserver agreement. Revised minimum criteria for these lesions were defined and found reproducible. This study has emphasized the value of pathologic examination as a supplement in placental perfusion models. Examination of the perfused cotyledon for trophoblastic vacuolization is recommended as an additional quality marker in perfusion models. The study also underlines the need for exact definitions of abnormality in frequent placental lesions.

Abstract
BACKGROUND Placental weight is an independent predictor of adverse perinatal outcome. However, risk factors for high and low placental weight are poorly understood. The objective of this study was to identify maternal, placental, and umbilical cord determinants of placental weight, before and after accounting for birthweight. METHODS This cohort study of 87,600 singleton births at the Royal Victoria Hospital in Montreal, Canada assessed the relationship between maternal, placental, and umbilical cord characteristics and placental weight (standardised for sex and gestational age). We separately examined risk factors for high (z-score >+1) and low (z-score <-1) placental weight. Multivariable logistic regression was used to study associations after adjusting for confounders and further adjusting for birthweight. RESULTS Chronic hypertension was associated with low placental weight {relative risk (RR) 2.1 [95% confidence interval (CI) 1.8, 2.4] and 1.8 [95% CI 1.5, 2.1] before and after accounting for birthweight}, while pre-eclampsia was associated with low placenta weight before, but not after adjustment for birthweight. Anaemia and gestational diabetes were linked with high placental weight (RRs 1.2-1.4, respectively) before and after adjustment for birthweight, while smoking was linked with high placental weight only after adjustment for birthweight (RR 1.4 [95% CI 1.3, 1.5]). Placental and cord determinants of high placental weight included chorioamnionitis, chorangioma/chorangiosis, circumvallate placenta, marginal cord insertion, and other cord abnormalities. CONCLUSIONS The broad range of risk factors for high placental weight suggests multiple aetiologic pathways. Future work should seek to understand the pathways by which the placenta adapts to unfavourable intrauterine conditions, which may provide insights into potential therapies.

Abstract
Placentas are usually submitted for pathologic examination based on obstetrical indications. We hypothesized that the placenta may have diagnostic value to the infant independent of obstetrical events. We specifically tested whether lymphohistiocytic villitis (noninfectious) would predict autoimmune or alloimmune disease based on transfer of activated maternal T-cells to the fetus and whether clinically silent placental separations (retroplacental hematomas, RPH) would predict neurologic injury in the infant. All placentas from consecutive deliveries had a routine pathologic examination of the placenta. The infants with placentas demonstrating inflammation of >1% of villi or RPH >2 cm and matched controls had their hospital charts reviewed and parental interviews by telephone at 5 to 7 years of age. The children of consented patients were also searched for in the office visits of the University of Louisville Pediatric Neurology and Rheumatology divisions. One thousand six hundred eighty-four patients consented to the follow-up study. We found no cases of autoimmune disease among 17 children with villitis >1%. Of 16 infants with RPH, 1 had cerebral palsy but with other placental findings, 1 had lethal hydranenecephaly, and the remainder had no adverse outcome. Of 15 children seen by a pediatric neurologist, none had the same placental lesion. The specific lesions of lymphohistiocytic villitis or asymptomatic RPH do not predict significant pediatric disease by 7 years of age. At least for these 2 lesions, the placenta does not have diagnostic value to the infant.

Abstract
AIM The study objective was to evaluate the pathological changes of the placenta in foetal death and foetal growth restriction and to find correlation of the findings with clinical causes. SETTING AND DESIGN Prospective study at a tertiary care hospital. MATERIAL AND METHODS Gross and histopathological examinations of the placentae were carried out in pregnancies with foetal demise (IUD) and Foetal Growth Restriction (FGR). STATISTICAL ANALYSIS SPSS, version 11.5. RESULTS Placentae of twenty seven women with foetal demise and of equal number of women with foetal growth restriction were studied. Placental weight was less than 10(th) percentile in 61.5% women in IUD group and in 93% women in the FGR group. Gross examination of placentae showed abnormalities in 12 (44%) women of IUD group and in 16 (59%) women of FGR group. Histopathological abnormalities were observed in 74.1% women of the IUD group and in 66.7% women of FGR group. Placental histopathology correlated with clinical risk factors in 60% women of IUD group and in 40% women of FGR group. Among the women with no clinically explainable cause for IUD and FGR, 86% and 57% had placental histopathological abnormalities respectively. CONCLUSION The histopathological abnormalities of the placenta can be used to document the clinical causes of foetal demise and growth restriction; it may explain the causes in cases of clinically unexplained foetal demise and foetal growth restriction.

Abstract
This study was conducted to determine the frequency of pre-defined clinical outcomes in relation to umbilical cord coiling indices >90th percentile and <10th percentile in an unselected population of >1,000 women with a singleton pregnancy resulting in livebirth delivering at or near term and to report these findings in the context of a systematic review. Placentas of consecutive deliveries from an unselected low-risk population with >15 cm attached umbilical cords were included in the study. Clinical outcomes included interventional delivery, birthweight <10th percentile, Apgar score <7 at 1 min, neonatal acidosis (pH<7.2) and admission to neonatal special care. Standard MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines were observed for the systematic review. Umbilical coiling index was determined for 1,082 placentas. Mean maternal age was 30.7 years (standard deviation [SD] =5.7) and 519 women (48 %) were primiparous. Mean cord length was 43 cm (SD=13) and mean cord coiling index 0.20 (SD=0.09). A total of 866 cords were normally coiled, and 108 cases were hypercoiled (>90th centile) and 108 cases were undercoiled (<10th percentile). There were no differences between cases of overcoiled, normally coiled or undercoiled cords for any clinical outcome studied. The systematic review yielded a small number of clinical studies which were too statistically and clinically heterogenous to permit meta-analysis. There is insufficient evidence either from this unselected cohort study or from a systematic review to support the previous suggestion that cord coiling index >90th centile or <10th centile is associated with adverse clinical outcome in an unselected population. Previous studies that draw a link between abnormal cord coiling and clinical outcome are generally too small and/or selective to allow meaningful conclusions or applicability to low-risk populations.

Abstract
Biobanks provide an important repository of samples for research purposes. However, for those samples to reflect the in vivo state, and for experimental reliability and reproducibility, careful attention to collection, processing and storage is essential. This is particularly true for the placenta, which is potentially subjected to stressful conditions during delivery, and sample collection may be delayed owing to routine postpartum inspection by clinical staff. In addition, standardisation of the collection procedure enables samples to be shared among research groups, allowing larger datasets to be established. Here, we provide an evidence-based and experts' review of the factors surrounding collection that may influence data obtained from the human placenta. We outline particular requirements for specific techniques, and propose a protocol for optimal sample collection. We recognise that the relevance of these factors, and of the sample types collected to a particular study will depend on the research questions being addressed. We therefore anticipate that researchers will select from the protocol to meet their needs and resources available. Wherever possible, we encourage researchers to extend their collection to include additional samples that can be shared on an international collaborative basis, with appropriate informed consent, to raise the quality, as well as quantity, of placental research.

Changes of placental syndecan-1 expression in preeclampsia and HELLP syndrome. Virchows Arch 2013; 463:445-58.

Abstract
Preeclampsia is characterized by maternal systemic anti-angiogenic and pro-inflammatory states. Syndecan-1 is a cell surface proteoglycan expressed by the syncytiotrophoblast, which plays an important role in angiogenesis and resolution of inflammation. Our aim was to examine placental syndecan-1 expression in preeclampsia with or without hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. Placentas were obtained from women in the following groups: (1) late-onset preeclampsia (n = 8); (2) early-onset preeclampsia without (n = 7) and (3) with HELLP syndrome (n = 8); (4) preterm controls (n = 5); and (5) term controls (n = 9). Tissue microarrays (TMAs) were constructed from paraffin-embedded placentas. TMA slides were immunostained for syndecan-1 and evaluated using microscopy, virtual microscopy, and semi-automated image analysis. Maternal sera from patients with preeclampsia (n = 49) and controls (n = 32) were immunoassayed for syndecan-1. BeWo cells were treated with Forskolin or Latrunculin B or kept in ischemic conditions. SDC1 expression and syndecan-1 production were investigated with qRT-PCR, confocal microscopy, and immunoassays. Syndecan-1 was localized to the syncytiotrophoblast apical membrane in normal placentas. Syndecan-1 immunoscores were higher in late-onset preeclampsia (p = 0.0001) and early-onset preeclampsia with or without HELLP syndrome (p = 0.02 for both) than in controls. Maternal serum syndecan-1 concentration was lower in preeclampsia (median, 673 ng/ml; interquartile range, 459-1,161 ng/ml) than in controls (1,158 ng/ml; 622-1,480 ng/ml). SDC1 expression and syndecan-1 immunostainings in BeWo cells and syndecan-1 concentrations in supernatants increased during cell differentiation. Disruption of the actin cytoskeleton with Latrunculin B decreased syndecan-1 release, while ischemic conditions increased it. Syncytiotrophoblastic syndecan-1 expression depends on the differentiation of villous trophoblasts, and trophoblastic syndecan-1 release is decreased in preeclampsia and HELLP syndrome. This phenomenon may be related to the disturbed syncytiotrophoblastic cortical actin cytoskeleton and associated with maternal anti-angiogenic and pro-inflammatory states in these syndromes.

Frequency and clinical significance of placental histological lesions in an unselected population at or near term. Virchows Arch 2011; 459:565-72. [PMID: 22038509 DOI: 10.1007/s00428-011-1157-z] [Citation(s) in RCA: 98] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2011] [Revised: 09/02/2011] [Accepted: 10/10/2011] [Indexed: 12/12/2022]
Abstract
Associations between specific placental histological abnormalities and obstetric outcomes are reported. However, most data are based either on high-risk cases or relate to case-control studies selected from those with abnormal placental histology findings, with the unavoidable biases that these approaches entail. This study reports the frequency of the several common, objective and predefined histological abnormalities of the placenta as identified by pathologists blinded to all clinical information. A total 1,153 women were recruited from an unselected population delivering at 34-43 weeks. Histological findings in common obstetric outcome groups were compared to those of the unselected population, and odds ratios and predictive values were calculated. Normal histological findings were present in 72.1% of pregnancies with normal outcomes and in 79.1%, 66.6%, 80%, and 74.8% of pregnancies affected by pre-eclampsia (PET), pregnancy-induced hypertension (PIH), gestational diabetes (GDM), and small for gestational age (SGA), respectively. Chronic placental underperfusion was seen more frequently in PIH (odds ratio (OR) 2) and SGA (OR 1.4), while villitis of unknown aetiology was observed more commonly in cases with PIH (OR 3.2). Fetal thrombotic vasculopathy was twice as common in cases with GDM whilst massive perivillous fibrin deposition was much more frequent in those with PET (OR 20.2) and SGA (OR 8.9). Chorangiomata were 13 times more common in pregnancies with PET. However, in all cases, positive predictive values were low, with the majority of cases with histological abnormalities being associated with normal outcome. At term, specific placental histological lesions are significantly more common in complicated pregnancies, but the clinical significance of such lesions in a specific case remains uncertain, since the majority will be identified from clinically uncomplicated normal pregnancies.

Abstract
Whilst individual histological features are well described, there are no universally agreed criteria as to what constitutes a clinically significant histological lesion of the placenta in an uncomplicated pregnancy, nor has the presence of such histological findings been systematically related to quantitative morphological characteristics of the placenta (such as placental shape, cord insertion and cord coiling). This study aims to explore this relationship and further to describe the incidence of predefined categories of histological lesions of the placenta in an unselected obstetric population recruited prior to delivery. The study is based upon the placental examination of 1,156 women with singleton pregnancies recruited prospectively in a single unit. Placentas were analysed where deliveries occurred between 34-43 weeks. The incidence of normal histological findings and specific histological categories, such as ascending genital tract infection, chronic placental underperfusion, intervillous thrombus and villitis of unknown aetiology, were noted. The relationship between placental morphological indices: coiling index, cord centrality index (distance of cord insertion on the chorionic plate from the centre) and eccentricity (shape of the placenta) and histological lesions was investigated. There were no significant differences between cord centrality and eccentricity between placentas with and without histological lesions except an association between hypercoiling of the umbilical cord and intervillous thrombosis and villitis of unknown aetiology (p = 0.024 and p = 0.009, respectively). The macroscopic morphological features of the placenta cannot predict the presence or absence of the histological placental lesions, nor are these lesions in general associated with differences in cord centrality, placental eccentricity or cord coiling.

Microarray profiling reveals that placental transcriptomes of early-onset HELLP syndrome and preeclampsia are similar. Placenta 2011; 32 Suppl:S21-9.

Abstract
BACKGROUND The involvement of the placenta in the pathogenesis of preeclampsia and HELLP syndrome is well established, and placental lesions are also similar in these two syndromes. Here we aimed to examine the placental transcriptome and to identify candidate biomarkers in early-onset preeclampsia and HELLP syndrome. METHODS Placental specimens were obtained at C-sections from women with early-onset preeclampsia and HELLP syndrome, and from controls who delivered preterm or at term. After histopathological examination, fresh-frozen placental specimens were used for microarray profiling and validation by qRT-PCR. Differential expression was analysed using log-linear models while adjusting for gestational age. Gene ontology and pathway analyses were used to interpret gene expression changes. Tissue microarrays were constructed from paraffin-embedded placental specimens and immunostained. RESULTS Placental gene expression was gestational age-dependent among preterm and term controls. Out of the 350 differentially expressed genes in preeclampsia and 554 genes in HELLP syndrome, 224 genes (including LEP, CGB, LHB, INHA, SIGLEC6, PAPPA2, TREM1, and FLT1) changed in the same direction (elevated or reduced) in both syndromes. Many of these encode proteins that have been implicated as biomarkers for preeclampsia. Enrichment analyses revealed similar biological processes, cellular compartments and biological pathways enriched in early-onset preeclampsia and HELLP syndrome; however, some processes and pathways (e.g., cytokine-cytokine receptor interaction) were over-represented only in HELLP syndrome. CONCLUSION High-throughput transcriptional and tissue microarray expression profiling revealed that placental transcriptomes of early-onset preeclampsia and HELLP syndrome largely overlap, underlying a potential common cause and pathophysiologic processes in these syndromes. However, gene expression changes may also suggest a more severe placental pathology and pronounced inflammatory response in HELLP syndrome than in preeclampsia.

Abstract
OBJECTIVES To examine, in patients with premature rupture of the amniotic membranes (PROM) at < 34 weeks of gestation, the relationship between fetal myocardial performance measured by the Tei index and fetal inflammatory response syndrome (FIRS). METHODS A case-control study was conducted including 15 preterm PROM patients with gestational age between 24 and 33 weeks admitted to Hospital de Clínicas de Porto Alegre, and 15 controls with the same gestational age range. Fetal echocardiography with Doppler was performed at admission for the preterm PROM group, with serial examinations every 7-10 days thereafter until delivery, and at the time of inclusion in the control group. Flow velocity waveforms were obtained for the left ventricle, from which the Tei index was calculated. Placental histopathology and perinatal outcome were compared between the groups. RESULTS The left ventricular Tei index was significantly greater in fetuses with preterm PROM compared with controls (0.63 +/- 0.13 vs. 0.51 +/- 0.10, P = 0.007). While there was no difference in isovolumetric times, the left ventricular ejection time was significantly shorter in the preterm PROM group (164 +/- 17 ms vs. 184 +/- 16 ms, P = 0.003). In the preterm PROM group, neonatal sepsis was diagnosed in 73.3%, and funisitis and chorionic vasculitis confirmed FIRS in 53.3%, compared with 6.7% for these three diagnoses in controls (P = 0.001). CONCLUSIONS These data provide further evidence that cardiac dysfunction is present in the setting of preterm PROM. The study of myocardial performance with the Tei index is a novel non-invasive approach to assess cardiac function and monitor the fetus affected with FIRS.

Abstract
CONTEXT It is the generally accepted practice to submit 1 or 2 membrane rolls when examining placentas. OBJECTIVE To determine whether obtaining additional sections would increase diagnostic yield and, if so, to what degree. DESIGN A membrane roll section was prospectively procured from each quadrant of its respective singleton placenta. These placentas were submitted for routine pathologic examination, the process of which was entirely separate from this study. All study sections were randomized and assigned new numbers, thereby blinding the pathologist to the placenta of origin. We evaluated the incidence of acute chorionitis/chorioamnionitis (AC/A) and atherosis when 1, 2, 3, or 4 slides were examined. The diagnostic yield from all possible combinations of single, pairs, and triplets of sections was tabulated. When an additional slide identified more extensive acute inflammation than what was demonstrated initially, the AC/A was upstaged. RESULTS With 1 section examined, 7 to 10 placentas had AC/A. With 2 sections, 10 to 15 placentas had AC/A; with 3 sections, 16 to 18 cases; and with 4 sections, 19 cases. Additional sections upstaged the AC/A diagnosis infrequently. A total of 4 of 53 placentas had atherosis, based on review of all 4 slides. One slide identified 1 to 3 cases of atherosis. With a second and third section, the yield increased to 2 to 4 and 3 to 4, respectively. CONCLUSIONS Review of a single membrane roll identified, at most, 53% of cases of AC/A and 50% of cases of atherosis. Additional sections increased the yield for both diagnoses in a roughly linear manner.
