Abstract
The placenta is the largest fetal organ, which connects the mother to the fetus and supports most aspects of organogenesis through the transport of nutrients and gases. However, further studies are needed to assess placental pathology as a reliable predictor of long-term physical growth or neural development in newborns. The Consensus Statement of the Amsterdam Placental Workshop Group (APWGCS) on the sampling and definition of placental lesions has resulted in diagnostic uniformity in describing the most common pathological lesions of the placenta and contributed to the international standardization of descriptions of placental pathology. In this narrative review, we reclassified descriptions of placental pathology from previously published papers according to the APWGCS criteria and comparatively assessed the relationship with infantile physical and/or neural development. After reclassification and reevaluation, placental pathology of maternal vascular malperfusion, one of the APWGCS criteria, emerged as a promising candidate as a universal predictor of negative infantile neurodevelopmental outcomes, not only in term and preterm deliveries but also in high-risk groups of very low birthweight newborns. However, there are few studies that examined placental pathology according to the full categories of APWGCS and also included low-risk general infants. It is necessary to incorporate the assessment of placental pathology utilizing APWGCS in the design of future birth cohort studies as well as in follow-up investigations of high-risk infants.

Abstract
Introduction: COVID-19 is a viral disease generated by a new coronavirus named SARS-CoV-2. The consequences of this virus on the human placenta and the newborn are still unclear. IL-6 can disturb the placenta's immunological homeostasis and be employed as an inflammatory marker for the poor prognosis of COVID-19 infection. Bax has some features like being a key protein regulating apoptotic mechanisms and plays an important role in both maintaining dynamic balance and integrity in the placenta as in many tissues. This study aims to indicate the impact of COVID-19 on inflammation and apoptotic pathways in the placenta by using IL-6 and Bax antibodies.
Material and Method: COVID-19 positive (n:10) and COVID-19 negative (n:10) normotensive placentas were included. Haematoxylin-eosin staining and immunohistochemical staining (IL-6 and Bax antibodies) were applied. Statistical data of immunohistochemical (IL-6 and Bax expression) staining results were assessed by analyzing the H-score. Biochemical parameters were recorded. Group means were analyzed with a nonparametric Kruskal Wallis Test.
Results: In the COVID-19 group, increased syncytial knots, fibrin deposition, inflammation, fibrinoid necrosis, neutrophil accumulation were observed. The COVID-19 group had considerably higher levels of IL-6 and Bax expression than the control group. Furthermore, COVID-19 patients had statistically lower WBC and higher CRP values than normotensive patients.
Conclusion: COVID-19 has been linked to placental inflammation and trophoblast cell damage, both of which can result in major maternal and fetal problems during pregnancy. We found intense IL-6 expression in the placentas of pregnant women with COVID-19 infection. A rise in IL-6 levels triggers CRP production, and this increase is linked to the severity of COVID-19 as a risk factor. Also, we suggested that COVID-19 infection triggers the apoptotic process in placental tissue by increasing the expression of the proapoptotic Bax protein. It is clinically very significant to follow up COVID-19 positive pregnancies for maternal and fetal health. During this follow-up, IL-6 and Bax expression levels in the placenta, together with histopathological findings and serum CRP levels, can guide the evaluation of the prognosis, severity and response to treatment of the disease.

Peripheral Nucleated Red Blood Cells and Mortality in Critically Ill Children. J Pediatr Hematol Oncol 2022; 44:79-83. [PMID: 34486569 DOI: 10.1097/mph.0000000000002294] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 06/25/2021] [Indexed: 10/20/2022]
Abstract
The present retrospective cohort study examines whether there is an association between circulating nucleated red blood cells (nRBCs) and mortality in critically ill children. nRBCs are erythropoietic progenitor cells not found in peripheral blood of healthy adults and children beyond the neonatal period. The presence of circulating nRBCs is associated with poor prognosis in adults and neonates, though little is known about their significance in children. Admissions to both the general and cardiac pediatric intensive care unit at the Stollery Children's Hospital in Edmonton, Alberta between January 1, 2015 and December 31, 2017 were examined, and logistic regression was performed to ascertain the association between the peak absolute nRBC counts and in-hospital mortality in critically ill children. A total of 2065 admissions were included. The number of admissions with detectable nRBCs was 386 (prevalence: 13.9%), and the number of deaths was 93 (mortality: 4.5%). A statistically significant association was found between the absolute value of nRBC peak and intensive care unit mortality (odds ratio=1.37; 95% confidence interval: 1.13-1.67; P=0.002) as well as hospital mortality (odds ratio=1.38; 95% confidence interval: 1.12-1.70; P=0.003) independent of the Pediatric Index of Mortality 3 score (PIM3). This result warrants more attention to nRBC values and their potential clinical use.

Abstract
The placenta plays a fundamental role during pregnancy for fetal growth and development. A suboptimal placental function may result in severe consequences during the infant's first years of life. In recent years, a new field known as neuroplacentology has emerged and it focuses on the role of the placenta in fetal and neonatal brain development. Because of the limited data, our aim was to provide a narrative review of the most recent knowledge about the relation between placental lesions and fetal and newborn neurological development. Papers published online from 2000 until February 2022 were taken into consideration and particular attention was given to articles in which placental lesions were related to neonatal morbidity and short-term and long-term neurological outcome. Most research regarding the role of placental lesions in neurodevelopment has been conducted on fetal growth restriction and preterm infants. Principal neurological outcomes investigated were periventricular leukomalacia, intraventricular hemorrhages, neonatal encephalopathy and autism spectrum disorder. No consequences in motor development were found. All the considered studies agree about the crucial role played by placenta in fetal and neonatal neurological development and outcome. However, the causal mechanisms remain largely unknown. Knowledge on the pathophysiological mechanisms and on placenta-related risks for neurological problems may provide clues for early interventions aiming to improve neurological outcomes, especially among pediatricians and child psychiatrists.

Disorders of placental villous maturation are present in one-third of cases with spontaneous preterm labor. J Perinat Med 2021; 49:412-430. [PMID: 33554577 PMCID: PMC8324068 DOI: 10.1515/jpm-2020-0138] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 11/09/2020] [Indexed: 12/16/2022]
Abstract
OBJECTIVES Spontaneous preterm labor is an obstetrical syndrome accounting for approximately 65-70% of preterm births, the latter being the most frequent cause of neonatal death and the second most frequent cause of death in children less than five years of age worldwide. The purpose of this study was to determine and compare to uncomplicated pregnancies (1) the frequency of placental disorders of villous maturation in spontaneous preterm labor; (2) the frequency of other placental morphologic characteristics associated with the preterm labor syndrome; and (3) the distribution of these lesions according to gestational age at delivery and their severity. METHODS A case-control study of singleton pregnant women was conducted that included (1) uncomplicated pregnancies (controls, n=944) and (2) pregnancies with spontaneous preterm labor (cases, n=438). All placentas underwent histopathologic examination. Patients with chronic maternal diseases (e.g., chronic hypertension, diabetes mellitus, renal disease, thyroid disease, asthma, autoimmune disease, and coagulopathies), fetal malformations, chromosomal abnormalities, multifetal gestation, preeclampsia, eclampsia, preterm prelabor rupture of the fetal membranes, gestational hypertension, gestational diabetes mellitus, and HELLP (hemolysis, elevated liver enzymes and low platelet count) syndrome were excluded from the study. RESULTS Compared to the controls, the most prevalent placental lesions among the cases were the disorders of villous maturation (31.8% [106/333] including delayed villous maturation 18.6% [62/333] vs. 1.4% [6/442], q<0.0001, prevalence ratio 13.7; and accelerated villous maturation 13.2% [44/333] vs. 0% [0/442], q<0.001). Other lesions in decreasing order of prevalence included hypercapillarized villi (15.6% [68/435] vs. 3.5% [33/938], q<0.001, prevalence ratio 4.4); nucleated red blood cells (1.1% [5/437] vs. 0% [0/938], q<0.01); chronic inflammatory lesions (47.9% [210/438] vs. 29.9% [282/944], q<0.0001, prevalence ratio 1.6); fetal inflammatory response (30.1% [132/438] vs. 23.2% [219/944], q<0.05, prevalence ratio 1.3); maternal inflammatory response (45.5% [195/438] vs. 36.1% [341/944], q<0.01, prevalence ratio 1.2); and maternal vascular malperfusion (44.5% [195/438] vs. 35.7% [337/944], q<0.01, prevalence ratio 1.2). Accelerated villous maturation did not show gestational age-dependent association with any other placental lesion while delayed villous maturation showed a gestational age-dependent association with acute placental inflammation (q-value=0.005). CONCLUSIONS Disorders of villous maturation are present in nearly one-third of the cases of spontaneous preterm labor.

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

Preterm birth subtypes, placental pathology findings, and risk of neurodevelopmental disabilities during childhood. Placenta 2019; 83:17-25.

Abstract
INTRODUCTION Preterm birth (PTB) and in-utero inflammation are recognized risk factors of neurodevelopmental disabilities (NDDs); however, their combined role in NDDs is unknown. We examined the independent and joint association of PTB and placental histological findings with the childhood risk of NDDs (overall and by subgroups including autism spectrum disorder (ASD) and ADHD). METHODS We analyzed data from the Boston Birth Cohort, where mother-infant pairs were enrolled at birth and followed from birth onwards. Birth outcomes, placental pathology and NDDs were obtained from electronic medical records. Placental pathology was categorized using a standardized classification system proposed by the Amsterdam Placental Workshop Group. RESULTS PTB (all, including spontaneous, medically indicated) was an independent risk factor for NDDs. Placental histological chorioamnionitis (CA) and PTB additively increased the odds of NDDs (aOR: 2.16, 95% CI: 1.37, 3.39), as well as ADHD (aOR: 2.75, 95% CI: 1.55, 4.90), other developmental disabilities (aOR: 1.96, 95% CI: 1.18, 3.25) and possibly ASD (aOR: 2.31, 95% CI: 0.99, 5.39). The above associations were more pronounced in spontaneous than medically indicated PTB. PTB alone in the absence of CA only had a moderate association with ASD and ADHD. Placental maternal vascular malperfusion alone or in combination with PTB was not associated with the risk of NDDs. DISCUSSION Our study provided new insights on PTB and NDDs by further considering preterm subtypes and placental histology. We revealed that children of spontaneous PTB along with histological CA were at the highest risk for a spectrum of NDDs.

Abstract
INTRODUCTION Women with adverse pregnancy outcomes (APOs) have excess risk of later life cardiovascular disease (CVD) perhaps related to an underlying high-risk vascular phenotype. We sought to determine if placental evidence of maternal malperfusion in uncomplicated pregnancies is associated with an increased risk of APOs in subsequent pregnancies. METHODS 536 women with more than one delivery and an initial uncomplicated pregnancy with placental pathology examination between 2008 and 2012 were included. APOs (small for gestational age, preterm delivery, or preeclampsia) were identified for each delivery. Multivariable log-binomial regression was used to estimate the risk of an APO in a subsequent pregnancy associated with MVM lesions in index pregnancy with adjustment for covariates. RESULTS Placental pathology from the initial pregnancy was compared between women with no APO in any pregnancy (-APO/-APO; n = 403) and women with an initial uncomplicated pregnancy and a subsequent adverse outcome (-APO/+APO; n = 133). Women with MVM lesions had an increased risk of an APO in a subsequent pregnancy relative to women with no MVM lesions after adjusting for covariates (aOR = 1.61; 95%CI = 1.06-2.46). Decidual vasculopathy was found in 13/133 (9.8%) of -APO/+APO women compared with 16/403 (4.0%) of -APO/-APO women, with an adjusted odds ratio of 2.51 (95% CI = 1.31-4.80). DISCUSSION MVM lesions found in placentas in uncomplicated pregnancies are associated with an increased risk of an adverse outcome in a subsequent pregnancy. Placental evidence of vascular malperfusion could offer a novel approach to risk stratification for subsequent pregnancy complications and perhaps future CVD.

Abstract
INTRODUCTION Maternal vascular malperfusion (MVM) lesions represent hypoxic-ischemic damage to the placenta, and they are associated with adverse pregnancy outcomes. Women with gestational diabetes (GDM) are at increased risk for pregnancy complications, so we set out to characterize the prevalence and clinical correlates of MVM lesions in this cohort. METHODS This was a retrospective cohort study of 1187/1374 (86.4%) women with GDM delivered between 2009 and 2012 who had placental pathology available. Placental lesions of all types were tabulated and grouped into constructs of related entities. MVM lesions specifically included villous infarcts, decidual vasculopathy, increased syncytial knots, perivillous fibrin, and fibrin deposition. We compared maternal characteristics between women with and without MVM lesions, and we also assessed the impact of these lesions on birth weight, preterm birth, and pre-eclampsia using multivariable logistic regression analysis. RESULTS MVM lesions were the most common placental lesion type in women with GDM (n = 362, 30.5%). Excess gestational weight gain was independently associated with MVM lesions (aOR 1.42, 95% CI 1.06-1.91, p = 0.02) after adjusting for maternal characteristics. MVM lesions were associated with lower birth weight (-90.3 g, 95% CI -148.0 to -32.7, p = 0.002), as well as a 2-fold increased risk for delivery of a small for gestational age infant (10.8 vs 5.9%, p = 0.01) in overweight and obese women. MVM lesions were also associated with increased risk for preterm birth <34 weeks (adjusted OR 2.36, 95% CI 1.31-4.23, p = 0.004) and hypertensive disorders of pregnancy (HDP; adjusted OR 1.58, 95% CI 1.13-2.22, p = 0.02). DISCUSSION Placental maternal vascular malperfusion lesions may be one pathway linking excess gestational weight gain to adverse pregnancy outcomes in women with GDM, and future studies are needed to identify metabolic factors that may explain this association.

Abstract
INTRODUCTION Placental pathology is an important contributor in preterm birth, both spontaneous and indicated. The aim of this study was to describe and compare placental histological features of spontaneous preterm birth versus indicated preterm birth. METHODS A case control study was performed at the University Medical Center Utrecht. Women with spontaneous or indicated preterm birth (17-37 weeks of gestation) delivered in 2009 were included. Women with a pregnancy complicated by congenital and/or chromosomal abnormalities were excluded. Placentas were systematically examined by an expert pathologist blinded for pregnancy outcome, except for gestational age. Placental histological abnormalities were classified into infectious inflammatory lesions and maternal vascular malperfusion lesions and compared between spontaneous and indicated preterm birth. Analysis was stratified for immature (17-23+6 weeks), extremely (24-27+6 weeks), very (28-31+6 weeks) and moderate/late (32-36+6 weeks) preterm birth. RESULTS We included 233 women, 121 women with spontaneous preterm birth and 112 women with indicated preterm birth. Among women with spontaneous extremely preterm birth, higher rates of severe chorioamnionitis were found (56.0% vs. 0%). Furthermore, a shift from infectious-inflammatory lesions to maternal vascular malperfusion lesions was seen after 28 weeks; in women with spontaneous very and moderate/late preterm birth, maternal vascular malperfusion lesions were the main finding (46.8% and 47.7% respectively). In women with indicated preterm birth, maternal vascular malperfusion lesions were most often contributing through all gestational age categories. CONCLUSION Maternal vascular malperfusion lesions are most frequent in both spontaneous and indicated very and moderate/late preterm birth. In spontaneous extreme preterm birth chorioamnionitis is the main finding.

A systematic review of placental pathology in maternal diabetes mellitus. Placenta 2014; 36:101-14. [PMID: 25524060 DOI: 10.1016/j.placenta.2014.11.021] [Citation(s) in RCA: 149] [Impact Index Per Article: 14.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2014] [Revised: 11/24/2014] [Accepted: 11/26/2014] [Indexed: 01/18/2023]
Abstract
INTRODUCTION During a pregnancy complicated by diabetes, the human placenta undergoes a number of functional and structural pathologic changes, such as increased placental weight and increased incidence of placental lesions including villous maturational defects and fibrinoid necrosis. The pathologic findings reported have differed among studies, potentially reflecting differences in type of diabetes, study methodology, or glycemic control of study participants. Alternatively, these discrepancies may represent different biologic adaptations to distinct metabolic diseases. METHODS We conducted a comprehensive review of English language citations in Pubmed and Embase using the keywords "diabetes", "placenta", AND "pathology". Abstracts were reviewed for relevance then full-text articles were reviewed in order to extract a comprehensive summary of current pathological findings associated with pregestational and gestational diabetes mellitus, as well as an understanding of the impact of glycemic control on placental pathology. RESULTS Placental abnormalities most consistently associated with maternal diabetes are an increased incidence of villous immaturity, increased measures of angiogenesis, and increased placental weight. CONCLUSIONS The literature suggests that, despite similarities in placental abnormalities, differences in placental pathology may reflect differences in pathophysiology among different types of diabetes. Consequently, standardization of terminology used to define placental lesions is warranted. Moreover, further research is needed to investigate the impact of pathophysiology, glycemic control and clinical factors, such as infant sex, weight and race, on placental structure and function.

Abstract
OBJECTIVE Acute atherosis is a lesion of the spiral arteries characterized by fibrinoid necrosis of the vessel wall, an accumulation of fat-containing macrophages, and a mononuclear perivascular infiltrate, which can be found in patients with preeclampsia, fetal death, small-for-gestational age, spontaneous preterm labor/premature prelabor rupture of membrane, and spontaneous mid-trimester abortion. This lesion is thought to decrease blood flow to the intervillous space which may lead to other vascular lesions of the placenta. The objective of this study was to test whether there is an association between acute atherosis and placental lesions that are consistent with maternal vascular underperfusion (MVU), amniotic fluid infection (AFI), fetal vascular thrombo-occlusive disease (FVTOD) or chronic inflammation. MATERIAL AND METHODS A retrospective cohort study of pregnant women who delivered between July 1998 and July 2014 at Hutzel Women's Hospital/Detroit Medical Center was conducted examine 16 457 placentas. The frequency of placenta lesions (diagnosed using the criteria of the Perinatal Section of the Society for Pediatric Pathology) was compared between pregnancies with and without acute atherosis. RESULTS Among 16 457 women who were enrolled, 10.2% (1671/16 457) were excluded, leaving 14 786 women who contributed data for analysis. Among them, the prevalence of acute atherosis was 2.2% (326/14 786). Women with acute atherosis were more than six times as likely as those without to have placental lesions consistent with maternal underperfusion (adjusted odds ratio - aOR: 6.7; 95% CI 5.2-8.6). To a lesser degree, acute atherosis was also associated with greater risks of having either lesions consistent with FVTOD (aOR 1.7; 95% CI 1.2-2.3) or chronic chorioamnionitis (aOR 1.9; 95% CI 1.3-3), but not with other chronic inflammatory lesions, after adjusting for gestational age at delivery. In contrast, women with acute atherosis were 60% less likely to have lesions consistent with AFI, adjusting for gestational age at delivery (aOR 0.4; 95% CI 0.3-0.5). CONCLUSIONS Acute atherosis is associated with increased risks of having placental lesions consistent with MVU, and to a lesser extent, chronic chorioamnionitis and those consistent with FVTOD.

Abstract
BACKGROUND The placenta plays a crucial role during pregnancy for growth and development of the fetus. Less than optimal placental performance may result in morbidity or even mortality of both mother and fetus. Awareness among pediatricians, however, of the benefit of placental findings for neonatal care, is limited. OBJECTIVES To provide a systematic overview of the relation between placental lesions and neonatal outcome. DATA SOURCES Pubmed database, reference lists of selected publications and important research groups in the field. STUDY APPRAISAL AND SYNTHESIS METHODS We systematically searched the Pubmed database for literature on the relation between placental lesions and fetal and neonatal mortality, neonatal morbidity and neurological outcome. We conducted three separate searches starting with a search for placental pathology and fetal and neonatal mortality, followed by placental pathology and neonatal morbidity, and finally placental pathology and neurological development. We limited our search to full-text articles published in English from January 1995 to October 2013. We refined our search results by selecting the appropriate articles from the ones found during the initial searches. The first selection was based on the title, the second on the abstract, and the third on the full article. The quality of the selected articles was determined by using the Newcastle-Ottawa Quality Assessment Scale. RESULTS Placental lesions are one of the main causes of fetal death, where placental lesions consistent with maternal vascular underperfusion are most important. Several neonatal problems are also associated with placental lesions, whereby ascending intrauterine infection (with a fetal component) and fetal thrombotic vasculopathy constitute the greatest problem. CONCLUSIONS The placenta plays a key role in fetal and neonatal mortality, morbidity, and outcome. Pediatricians should make an effort to obtain the results of placental examinations.

Abstract
BACKGROUND The placenta plays a crucial role during pregnancy and dysfunction causes long-term neurological problems. Identifying placenta-related risks for neurological problems shortly after birth may provide clues for early interventions aiming to improve neurological outcome. OBJECTIVE To determine the association between placental pathology and neurological morbidity in preterm infants during the first two weeks after birth. STUDY DESIGN Placentas of 52 singleton, preterm infants (GA: 25-31weeks, BW: 560-2250 grammes) were examined for histopathology. The infants' neurological condition shortly after birth was determined by assessing the quality of their general movements (GMs): normal, abnormal, or hypokinetic, on days 5, 8, and 15. A motor optimality score (MOS) was also assigned. RESULTS Examination of the placentas revealed maternal vascular underperfusion (n=29), ascending intrauterine infection (AIUI) (n=19), villitis of unknown aetiology (n=6), chronic deciduitis (n=11), foetal thrombotic vasculopathy (FTV) (n=9), and elevated nucleated red blood cells (NRBCs) as a marker for foetal hypoxia (n=7). None of the placental lesions were significantly associated with the quality of GMs or MOS. CONCLUSIONS This study indicated that placental lesions were not associated with infants' neurological condition as measured by the quality of their general movements during the first two weeks after birth.
