Abstract
PURPOSE Pediatric pulmonary hypertension (PH) is a condition characterized by elevated pulmonary arterial pressure, which has the potential to be life-limiting. The etiology of pediatric PH varies. When compared with adult cohorts, the etiology is often multifactorial, with contributions from prenatal, genetic, and developmental factors. This review aims to provide an up-to-date overview of the causes and classification of pediatric PH, describe current therapeutics in pediatric PH, and discuss upcoming and necessary research in pediatric PH. METHODS PubMed was searched for articles relating to pediatric pulmonary hypertension, with a particular focus on articles published within the past 10 years. Literature was reviewed for pertinent areas related to this topic. FINDINGS The evaluation and approach to pediatric PH are unique when compared with that of adults, in large part because of the different, often multifactorial, causes of the disease in children. Collaborative registry studies have found that the most common disease causes include developmental lung disease and subsets of pulmonary arterial hypertension, which includes genetic variants and PH associated with congenital heart disease. Treatment with PH-targeted therapies in pediatrics is often guided by extrapolation of adult data, small clinical studies in pediatrics, and/or expert consensus opinion. We review diagnostic considerations and treatment in some of the more common pediatric subpopulations of patients with PH, including developmental lung diseases, congenital heart disease, and trisomy 21. IMPLICATIONS The care of pediatric patients with PH requires consideration of unique pediatric-specific factors. With significant variability in disease etiology, ongoing efforts are needed to optimize treatment strategies based on disease phenotype and guide evidence-based practices.

[PMID: 36859279 PMCID: PMC9976428 DOI: 10.1186/s12884-023-05448-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 02/15/2023] [Indexed: 03/03/2023] Open
Abstract
BACKGROUND Preeclampsia (PE) is a complication of pregnancy that causes long-term adverse outcomes for the mother and fetus and may even lead to death. Oxidative stress caused by the imbalance of oxidants and antioxidants in the placenta has been considered as one of the key mechanisms of preeclampsia (together with inflammation, etc.), in which the placental mitochondria play an important role. The expression of hypoxia-inducible factor-1 (HIF-1α) and vascular endothelial growth factor (VEGF) is known to be increased in patients with PE. Mitochondrial ferritin (FtMt) is known to protect the mitochondria from oxidative stress, although its specific role in PE remains unclear. METHODS We used qRT-PCR and western blotting to detect the expression levels of FtMt, HIF-1α, and VEGF in placental tissues from patients with PE. Human chorionic trophoblast cells were also administered with hypoxia treatment, followed by the detection of cell proliferation, invasion and angiogenic capacity by CCK8, Transwell, and endothelial cell angiogenesis assays; we also detected the expression of HIF-1α and VEGF in these cells. Finally, overexpression or inhibitory FtMt lentiviral vectors, along with negative control vectors, were constructed and transfected into hypoxia-treated human chorionic trophoblast cells; this was followed by analyses of cell function. RESULTS The expression levels of FtMt, HIF-1α and VEGF in the PE group were higher than those in the control group (P < 0.05). Following hypoxia, there was an increase in the expression levels of HIF-1α and VEGF protein in trophoblast cells. There was also an increase in invasion ability and vascular formation ability along with a reduction in cell proliferation ability. These effects were reversed by transfecting cells with the knockout FtMt lentivirus vector. The differences were statistically significant. CONCLUSION Analyses showed that FtMt plays a key role in the vascular regulation of PE trophoblast cells after hypoxia possibly acting via the HIF-1α/VEGF signaling pathway. These results provide us an enhanced understanding of the pathogenesis of PE and suggest that the HIF-1α/VEGF signaling pathway represents a new target for the treatment of PE.

Abstract
Hypertensive disorders complicating pregnancy (HDCP) are common pregnancy-related disorders. In this study, we aimed to study the clinical value of flow-mediated dilation (FMD) in HDCP and its association with endothelial dysfunction and HDCP-related factors. 160 HDCP patients and 120 healthy pregnancies were enrolled in the study. The expressions of endothelial function markers and FMD were determined. In addition, their correlations in HDCP patients were also analyzed using Pearson's correlation analysis. FMD value decreased gradually from normal pregnancy to severe PE. The levels of plasma nitric oxidase (NO) were significantly lower in the HDCP group than those in the control group, while the levels of plasma endothelin-1 (ET-1) were increased dramatically in the HDCP group. Moreover, the levels of placental growth factor (PLGF) in HDCP women were significantly lower, while the soluble FMS-like tyrosine kinase 1 (sFLt-1) levels were markedly higher than those in control. In addition, the FMD value was correlated with the levels of plasma NO, ET-1, PLGF and sFlt1. It was also found that lower levels of FMD correspond to endothelial dysfunction and abnormal concentrations of PLGF and sFlt-1. The FMD value was associated with endothelial function indicators and could be a strong and non-invasive measure to predict HDCP. The association between the FMD values and endothelial function indicators in HDCP could be helpful for the prediction of pregnant hypertension more accurately.

Abstract
OBJECTIVE Biomarkers have become important in the prognosis and diagnosis of various diseases. High-throughput methods, such as RNA sequencing facilitate the detection of differentially expressed genes (DEGs), hence potential biomarker candidates. Individual studies suggest long lists of DEGs, hampering the identification of clinically relevant ones. Concerning preeclampsia - a major obstetric burden with high risk for adverse maternal and/or neonatal outcomes - limitations in diagnosis and prediction are still important issues. We, therefore, developed a workflow to facilitate the screening for biomarkers. METHODS On the basis of the tool DESeq2, a comprehensive workflow for identifying DEGs was established, analyzing data from several publicly available RNA-sequencing studies. We applied it to four RNA-sequencing datasets (one blood, three placenta) analyzing patients with preeclampsia and normotensive controls. We compared our results with other published approaches and evaluated their performance. RESULTS We identified 110 genes that are dysregulated in preeclampsia, observed in at least three of the studies analyzed, six even in all four studies. These included FLT-1, TREM-1, and FN1, which either represent established biomarkers at protein level, or promising candidates based on recent studies. For comparison, using a published meta-analysis approach, 5240 DEGs were obtained. CONCLUSION This study presents a data analysis workflow for preeclampsia biomarker screening, capable of identifying promising biomarker candidates, while drastically reducing the numbers of candidates. Moreover, we were also able to confirm its performance for heart failure. This approach can be applied to additional diseases for biomarker identification, and the set of DEGs identified in preeclampsia represents a resource for further studies.

Abstract
The clinical usefulness of serum placental growth factor (PlGF) as a predictive biomarker of preeclampsia is currently being examined. However, there are still conflicting results in the literature. We assessed the association between maternal low PlGF levels and the occurrence and severity of preeclampsia. This was an analytical cross-sectional study conducted among 60 women with preeclampsia, and an equal number of matched normotensive pregnant women. PlGF concentrations were analysed using the ELISA method. Bivariate and multivariate analysis was used to test for the association between low maternal PlGF levels and the occurrence of preeclampsia and its severity. Statistical significance was reported at p < .05. The study showed that having a low maternal PlGF level (Adjusted OR 14.23; 95%CI 8.06, 29.71) together with being primigravid (Adjusted OR 3.97; 95%CI 1.03, 6.18) and having an unbooked pregnancy (Adjusted OR 8.07; 95%CI 2.06, 19.40) were independently associated with preeclampsia. We established an association between low maternal PlGF levels and preeclampsia, but no similar association with severe preeclampsia. The use of PlGF as a potential predictive marker and a reliable screening tool may have a profound implication on the prevention of preeclampsia and the subsequent reduction in its associated morbidity and mortality.Impact statementWhat is already known on this subject? The utility of serum placental growth factor (PlGF) as a predictive biomarker of preeclampsia is currently being examined, however, there are conflicting results of its clinical usefulness in the literature.What do the results of this study add? This study that assessed the association between maternal low PlGF levels and the occurrence and severity of preeclampsia showed that having a low maternal PlGF level together with being primigravid and having an unbooked pregnancy were independently associated with the occurrence of preeclampsia. However, we were unable to establish any significant relationship between maternal PlGF and the severity of preeclampsia.What are the implications of these findings for clinical practice and/or further research? We opined that the use of PlGF as a potential predictive marker and a reliable screening tool may have a profound clinical implication on the prevention and reduction in the associated morbidity and mortality of preeclampsia. However, there is an urgent need for more robust longitudinal studies to define the regulation of placental vascular development and the clinical usefulness of maternal serum PlGF and other placental biomarkers as potential screening tools for preeclampsia among black African women.

Abstract
Preeclampsia (PE) is a leading condition threatening pregnant women and their offspring. The offspring of PE pregnancies have a high risk of poor neurodevelopmental outcomes and neuropsychological diseases later in life. However, the pathophysiology and pathogenesis of poor neurodevelopment remain undetermined. Abnormal placental functions are at the core of most PE cases, and recent research evidence supports that the placenta plays an important role in fetal brain development. Here, we summarize the relationship between abnormal fetal brain development and placental dysfunction in PE conditions, which include the dysfunction of nutrient and gas-waste exchange, impaired angiogenesis stimulation, abnormal neurotransmitter regulation, disrupted special protectors, and immune disorders. All these factors could lead to poor neurodevelopmental outcomes.

Abstract
Hypertensive disorders complicating pregnancy (HDCP) is a systemic disease among pregnant women. Therefore, the prevention and prediction of hypertension during pregnancy are critical. This study aimed to clarify whether the vascular endothelial function of women with gestational hypertension was linked to placental growth factor. A total of 200 pregnant women were enrolled in our study and subsequently divided into two groups: the HDCP group and the normal pregnancy controls. The levels of serum placental growth factor, as well as plasma endothelin-1 and nitric oxide, between the two groups were measured. In addition, the endothelial function indexes, including pressure-strain elasticity coefficient (EP), the common carotid stiffness index (β), arterial compliance, single-point pulsed-wave velocity, and augment index (AI) of bilateral common carotid arteries, were compared between the HDCP and control groups using the echo tracking technique. In our study, the level of placental growth factor in the HDCP group was significantly lower than the control group. Furthermore, our results clarified that endothelin-1 increased while nitric oxide decreased in the HDCP group compared with the control group. On the other hand, we found that EP, β, pulsed-wave velocity and augment index values were significantly higher in the HDCP group than in the control group (P < 0.001). However, the value of arterial compliance was significantly decreased in patients of the HDCP group compared with the control group (P < 0.001). In conclusion, the association between serum placental growth factor and vascular endothelial function in HDCP could serve as a more accurate predictive factor of pregnant hypertension.

Abstract
Eclampsia is diagnosed in pregnant women who develop novel seizures. Our laboratory showed that the reduced uterine perfusion pressure (RUPP) rat model of preeclampsia displays reduced latency to drug-induced seizures. While acid sensing ion channels (ASIC1a and 3) are important for reducing seizure longevity and severity, the role of ASIC2a in mediating seizure sensitivity in pregnancy has not been investigated. We hypothesized that 1) RUPP reduces hippocampal ASIC2a, and 2) pregnant mice with reduced ASIC2a (ASIC2a+/-) have increased seizure sensitivity. On gestational day 18.5, hippocampi from sham and RUPP C57BL/6 mice were harvested, and ASIC2a was assessed using Western blot. Pregnant wild-type and ASIC2a+/- mice received 40 mg/kg of pentylenetetrazol (i.p.) and were video recorded for 30 min. Behaviors were scored using a modified Racine scale (0-7: 0 = no seizure; 7 = respiratory arrest/death). Seizure severity was classified as mild (score = 1-3) or severe (score = 4-7). RUPP mice had reduced hippocampal and placental ASIC2a protein. ASIC2a+/- mice had reduced latency to seizures, increased seizure duration, increased severe seizure duration, and higher maximum seizure scores. Reduced hippocampal ASIC2a in RUPP mice and increased seizure activity in pregnant ASIC2a+/- mice support the hypothesis that reduced ASIC2a increases seizure sensitivity associated with the RUPP.

Abstract
Preeclampsia is a multisystem, multiorgan hypertensive disorder of pregnancy responsible for maternal and perinatal morbidity and mortality in low- and middle-income countries. The classic diagnostic features hold less specificity for preeclampsia and its associated adverse outcomes, suggesting a need for specific and reliable biomarkers for the early prediction of preeclampsia. The imbalance of pro- and antiangiogenic circulatory factors contributes to the pathophysiology of preeclampsia. Several studies have examined the profile of angiogenic factors in preeclampsia to search for a biomarker that will improve the diagnostic ability of preeclampsia and associated adverse outcomes. This may help in more efficient patient management and the reduction of associated health care costs. This article reviews the findings from previous studies published to date on angiogenic factors and suggests a need to apply a multivariable model from the beginning of pregnancy and continuing throughout gestation for the early and specific prediction of preeclampsia.

Abstract
Preeclampsia (PE) is one of the main causes of maternal death and perinatal morbidity and mortality. Considering that histone deacetylase 4 (HDAC4) activity could relate to trophoblast cell motility and be antagonized by miR-29b, the aim of the present study was to investigate the ability of HDAC4 to regulate placental trophoblast cells by miR-29b. We assessed the cytological changes of PE patients, and the expression and cellular localization of HDAC4 and LC3 by histological analysis, immunohistochemistry, western blot assay, and immunofluorescence staining assay. We observed the effect of hypoxia on HDAC4, the correction of HDAC4/miR-29b, and the effects of HDAC4/miR-29b on HTR8 cells by dual-luciferase, quantitative real-time PCR, western blot assay, and flow cytometry assay. Here, we first found that HDAC4 was lowly expressed in PE tissues, while LC3 was highly expressed. In addition, the expression of HDAC4 was inhibited by hypoxia in HTR8 cells. Furthermore, our data showed that HDAC4 activity could be antagonized by miR-29b. We highlighted that miR-29b specifically targeted HDAC4 in trophoblast cells and both molecules were involved in a functional loop. Altogether, our findings demonstrated that silencing of HDAC4 could trigger cell autophagy and apoptosis directly by miR-29b in placental trophoblast cells of PE.

Abstract
Abnormal placental vasculature is associated with preeclampsia. Preeclampsia is of two types, i.e., early- and late-onset preeclampsia (LOP), both having different etiologies. We have earlier demonstrated low levels of omega-3 fatty acids and vitamin E in women with preeclampsia. The current study examines the effect of maternal omega-3 fatty acids and vitamin E supplementation on angiogenic factors in a rat model of preeclampsia. Pregnant rats were divided into a total of five groups control, early-onset preeclampsia (EOP); LOP; EOP supplemented with omega-3 fatty acid and vitamin E and LOP supplemented with omega-3 fatty acid and vitamin E. Preeclampsia was induced by administering L-nitroarginine methylester (L-NAME) at the dose of 50 mg/kg body weight/day. The vascular endothelial growth factor gene expression and protein levels were lower (p < 0.01 for both) in animals from both EOP as well as LOP groups (p < 0.01). In the EOP group, the protein levels of VEGF receptor-1 were also lower (p < 0.01). Supplementation of omega-3 fatty acids and vitamin E to LOP improved the levels of VEGF and VEGF receptor-1 only in the LOP but not in the EOP group. In the EOP group, the gene expression of hypoxia inducible factor 1 alpha (HIF-1α) in the placenta was higher (p < 0.05) and supplementation normalized these levels. Our findings indicate that maternal supplementation of omega-3 fatty acids and vitamin E has differential effect on preeclampsia subtypes.

Abstract
INTRODUCTION The maternal endothelial dysfunction characteristic of preeclampsia arises, in part, from excessive placental production of anti-angiogenic factors, including soluble Flt-1, soluble endoglin and activin A, inducing oxidative stress. We assessed whether the antioxidant and NRF2-activator sulforaphane could mitigate endothelial and trophoblast dysfunction in vitro. METHODS We induced dysfunction in human umbilical vein endothelial cells (HUVECs) with TNF-α, assessing endothelial activation and dysfunction (endothelin-1, vascular cell adhesion molecule; VCAM1, intracellular adhesion molecule; ICAM1, e-selectin and endothelial permeability) in the presence or absence of sulforaphane. We also assessed the effects of sulforaphane in mitigating hypoxic and hyperoxic injury in term placental explants by measuring secretion of anti-angiogenic factors. To assess the role of NRF2 we silenced NRF2 in HUVECs and primary trophoblast cells. RESULTS Sulforaphane reduced TNF-α mediated HUVEC secretion of endothelin-1, VCAM1, ICAM1 and E-selectin, and prevented increased endothelial permeability. In placental explants, sulforaphane reduced the secretion of soluble Flt-1, soluble endoglin and activin A. Sulforaphane induced activation and nuclear translocation of NRF2 in HUVECs, inducing heme oxygenase 1. NRF2 silencing blocked some but not all of sulforaphane's effects in HUVECs. NRF2 silencing did not prevent sulforaphane's inhibition of trophobast secretion of soluble Flt-1 or activin A. CONCLUSION In reducing placental and endothelial oxidative stress, sulforaphane may offer a new adjuvant therapeutic approach for the treatment of preeclampsia.

Abstract
INTRODUCTION Preeclampsia is a disease specific to pregnancy characterised by new onset hypertension with maternal organ dysfunction and/or fetal growth restriction. It remains a major cause of maternal and perinatal morbidity and mortality. For fifty years, antihypertensives have been the mainstay of treating preeclampsia, reducing maternal morbidity and mortality. With increased knowledge of the mechanisms underlying the disease has come opportunities for novel therapies that complement antihypertensives by protecting the maternal vasculature. Areas covered: In this review, the authors consider, in detail, the antihypertensives commonly used today in the emergency care of women with severe preeclampsia. They also review less common anti-hypertensive agents and discuss the role of magnesium sulphate in the management of preeclampsia and the prevention of eclampsia. Finally, they explore novel therapeutics for the acute management of preeclampsia. Expert opinion: The rapid control of maternal hypertension will, and must, remain the mainstay of emergency treatment for women with severe preeclampsia. The role of magnesium sulphate as a primary prevention for eclampsia is context dependant and should not displace a focus on correcting blood pressure safely. The exploration of novel adjuvant therapies will likely allow us to prolong pregnancy longer and improve perinatal outcomes safely for the mother.

Abstract
Copeptin, a marker of arginine vasopressin (AVP) secretion, is elevated throughout human pregnancies complicated by preeclampsia (PE), and AVP infusion throughout gestation is sufficient to induce the major phenotypes of PE in mice. Thus, we hypothesized a role for AVP in the pathogenesis of PE. AVP infusion into pregnant C57BL/6J mice resulted in hypertension, renal glomerular endotheliosis, intrauterine growth restriction, decreased placental growth factor (PGF), altered placental morphology, placental oxidative stress, and placental gene expression consistent with human PE. Interestingly, these changes occurred despite a lack of placental hypoxia or elevations in placental fms-like tyrosine kinase-1 (FLT1). Coinfusion of AVP receptor antagonists and time-restricted infusion of AVP uncovered a mid-gestational role for the AVPR1A receptor in the observed renal pathologies, versus mid- and late-gestational roles for the AVPR2 receptor in the blood pressure and fetal phenotypes. These findings demonstrate that AVP is sufficient to initiate phenotypes of PE in the absence of placental hypoxia, and indicate that AVP may mechanistically (independently, and possibly synergistically with hypoxia) contribute to the development of clinical signs of PE in specific subtypes of human PE. Additionally, they identify divergent and gestational time-specific signaling mechanisms that mediate the development of PE phenotypes in response to AVP.

Abstract
Pre-eclampsia is a common obstetric complication globally responsible for a significant burden of maternal and perinatal morbidity and mortality. Central to its pathophysiology is the anti-angiogenic protein, soluble fms-like tyrosine kinase-1 (sFLT-1). sFLT-1 is released from a range of tissues into the circulation, where it antagonizes the activity of vascular endothelial growth factor and placental growth factor leading to endothelial dysfunction. It is this widespread endothelial dysfunction that produces the clinical features of pre-eclampsia including hypertension and proteinuria. There are multiple splice variants of sFLT-1. One, known as sFLT-1 e15a, evolved quite recently and is only present in humans and higher order primates. This sFLT-1 variant is also the main sFLT-1 secreted from the placenta. Recent work has shown that sFLT-1 e15a is significantly elevated in the placenta and circulation of women with pre-eclampsia. It is also biologically active, capable of causing endothelial dysfunction and the end-organ dysfunction seen in pre-eclampsia. Indeed, the over-expression of sFLT-1 e15a in mice recapitulates the pre-eclamptic phenotype in pregnancy. Therefore, here we propose that sFLT-1 e15a may be the sFLT-1 variant primarily responsible for pre-eclampsia, a uniquely human disease. Furthermore, this placental-specific sFLT-1 variant provides promise for use as an accurate biomarker in the prediction or diagnosis of pre-eclampsia.

Abstract
OBJECTIVE The factors angiopoeitin-2 (Ang-2), endoglin (Eng), and placental growth factor (PlGF) have been implicated in the pathophysiology of preeclampsia (PE). This study assessed their serum levels in HIV-negative and HIV-positive pregnant normotensive and pre-eclamptic women. METHODS Participants were recruited at the antenatal clinic, serum samples were evaluated using the Bioplex Human Cancer Biomarker (panel 2). RESULTS Ang-2 and Eng levels were higher, whilst PlGF levels were lower in the PE compared with the normotensive group. Pregnancy type had no significant effect on Ang-2 and showed a significant interaction with Eng (p < 0.0001) and PlGF (p = 0.0033). HIV status had no significant effect on angiopoeitin-2 (p = 0.4), Eng (p = 0.4), and PlGF (p = 0.7) but the levels were slightly higher in the HIV-negative cohort. CONCLUSIONS This study demonstrates an elevation of Ang-2 and Eng in pre-eclamptic compared with normotensive pregnant women implicating their role in its pathogenesis.

Abstract
OBJECTIVE To measure and correlate the level of vascular endothelial growth factors A, C, and D in HIV-associated pre-eclampsia. METHODS VEGF-A, VEGF-C, and VEGF-D were measured in serum of 76 normotensive and pre-eclamptic pregnant women stratified by HIV status using Bio-Plex. RESULTS No significant difference was shown between pre-eclamptic and normotensive and between HIV negative and positive women. A strong significant positive correlation was demonstrated between VEGF-A and VEGF-C, VEGF-A and VEGF-D, and VEGF-C and VEGF D (p < 0.0001). CONCLUSION This study demonstrates a significant correlation between VEGF-A, VEGF-C, and VEGF-D and no difference in pre-eclamptic and normotensive pregnant women stratified by HIV status suggesting some neutralization of the immune response in HIV-associated pre-eclampsia.

Abstract
The connection between maternal hematological status and pregnancy outcome has been shown by many independent researchers. Attention was initially focused on the adverse effects of moderate and severe anemia. Interestingly, some studies revealed that mild anemia was associated with optimal fetal development and was not affecting pregnancy outcome. The explanation for this phenomenon became a target for scientists. Hemodilution, physiologic anemia and relative decrease in hemoglobin concentration are the changes observed during pregnancy but they do not explain the reasons for the positive influence of mild anemia on a fetomaternal unit. It is hypothesized that hemodilution facilitates placental perfusion because blood viscosity is reduced. Subsequently, it may lead to a decline in hemoglobin concentration. Anemia from its definition implies decreased oxygen carrying capacity of the blood and can result in hypoxemia and even hypoxia, which is a common factor inducing new blood vessels formation. Therefore, we raised the hypothesis that the lowered hemoglobin concentration during pregnancy may upregulate vascular growth factor receptors expression such as VEGFR-1 (Flt-1) and VEGFR-2 (FLK-1/KDR). Consecutively, increased fetoplacental vasculogenesis and angiogenesis provide further expansion of vascular network development, better placental perfusion and hence neither fetus nor the mother are affected.

Abstract
The splice isoforms of vascular endothelial growth A (VEGF) each have different affinities for the extracellular matrix (ECM) and the coreceptor NRP1, which leads to distinct vascular phenotypes in model systems expressing only a single VEGF isoform. ECM-immobilized VEGF can bind to and activate VEGF receptor 2 (VEGFR2) directly, with a different pattern of site-specific phosphorylation than diffusible VEGF. To date, the way in which ECM binding alters the distribution of isoforms of VEGF and of the related placental growth factor (PlGF) in the body and resulting angiogenic signaling is not well-understood. Here, we extend our previous validated cell-level computational model of VEGFR2 ligation, intracellular trafficking, and site-specific phosphorylation, which captured differences in signaling by soluble and immobilized VEGF, to a multi-scale whole-body framework. This computational systems pharmacology model captures the ability of the ECM to regulate isoform-specific growth factor distribution distinctly for VEGF and PlGF, and to buffer free VEGF and PlGF levels in tissue. We show that binding of immobilized growth factor to VEGF receptors, both on endothelial cells and soluble VEGFR1, is likely important to signaling in vivo. Additionally, our model predicts that VEGF isoform-specific properties lead to distinct profiles of VEGFR1 and VEGFR2 binding and VEGFR2 site-specific phosphorylation in vivo, mediated by Neuropilin-1. These predicted signaling changes mirror those observed in murine systems expressing single VEGF isoforms. Simulations predict that, contrary to the 'ligand-shifting hypothesis,' VEGF and PlGF do not compete for receptor binding at physiological concentrations, though PlGF is predicted to slightly increase VEGFR2 phosphorylation when over-expressed by 10-fold. These results are critical to design of appropriate therapeutic strategies to control VEGF availability and signaling in regenerative medicine applications.

Abstract
Offspring of hypertensive pregnancies are more likely to have microvascular rarefaction and increased blood pressure in later life. We tested the hypothesis that maternal angiogenic profile during a hypertensive pregnancy is associated with fetal vasculogenic capacity and abnormal postnatal microvascular remodeling. Infants (n=255) born after either hypertensive or normotensive pregnancies were recruited for quantification of postnatal dermal microvascular structure at birth and 3 months of age. Vasculogenic cell potential was assessed in umbilical vein endothelial cells from 55 offspring based on in vitro microvessel tube formation and proliferation assays. Maternal angiogenic profile (soluble fms-like tyrosine kinase-1, soluble endoglin, vascular endothelial growth factor, and placental growth factor) was measured from postpartum plasma samples to characterize severity of pregnancy disorder. At birth, offspring born after hypertensive pregnancy had similar microvessel density to those born after a normotensive pregnancy, but during the first 3 postnatal months, they had an almost 2-fold greater reduction in total vessel density (-17.7±16.4% versus -9.9±18.7%; P=0.002). This postnatal loss varied according to the vasculogenic capacity of the endothelial cells of the infant at birth (r=0.49; P=0.02). The degree of reduction in both in vitro and postnatal in vivo vascular development was proportional to levels of antiangiogenic factors in the maternal circulation. In conclusion, our data indicate that offspring born to hypertensive pregnancies have reduced vasculogenic capacity at birth that predicts microvessel density loss over the first 3 postnatal months. Degree of postnatal microvessel reduction is proportional to levels of antiangiogenic factors in the maternal circulation at birth.

Abstract
INTRODUCTION Normal placental vascular development depends on multiple interactions of many regulatory molecules including pro and antiangiogenic proteins. It is considered that these vascular modulators might be one of the factors responsible for development hypertensive disorders in pregnancy. OBJECTIVE To evaluate and compare the early pregnancy (11-14 week of gestation) serum level of angiogenic proteins sFlt1, VEGF i PIGF between different types of pregnancy related hypertensive disorders. MATERIALS AND METHODS The study included 177 pregnant women between 11 and 14 weeks of gestation, divided into four study subgroups (preeclampsia group-41, gestational hypertension group-31, chronic hypertension group-32 and miscarriage group-19) and control group-54. Blood samples (serum) were taken for measuring sFlt1, VEGF i PIGF by a quantitative ELISA technique and measuring other biochemical and hematological parameters. RESULTS Significantly higher levels of sFlt1 were in the subgroups with preeclampsia and miscarriages, significantly lower level of VEGF in the all study subgroups and lover level of PIGF were in miscarriage group. In the groups with chronic and gestational hypertension there were higher level of sFlt1 and lover level of VEGF than in the control group, but the differences did not reach statistical significance. CONCLUSION Early pregnancy imbalance between antiangiogenic protein sFlt1 and proangiogenic molecules VEGF and PIGF could have impact on pathophysiology of placental disorders which leads to development of pregnancy related hypertensive disorders.

Abstract
Triazole fungicides are one of the top ten classes of current-use pesticides. Although exposure to triazole fungicides is associated with reproductive toxicity in mammals, limited information is available regarding the effects of triazole fungicides on human placental trophoblast function. Tebuconazole (TEB) is a common triazole fungicide that has been extensively used for fungi control. In this work, we showed that TEB could reduce cell viability, disturb normal cell cycle distribution and induce apoptosis of human placental trophoblast cell line HTR-8/SVneo (HTR-8). Bcl-2 protein expression decreased and the level of Bax protein increased after TEB treatment in HTR-8 cells. The results demonstrated that this fungicide induced apoptosis of trophoblast cells via mitochondrial pathway. Importantly, we found that the invasive and migratory capacities of HTR-8 cells decreased significantly after TEB administration. TEB altered the expression of key regulatory genes involved in the modulation of trophoblast functions. Taken together, TEB suppressed human trophoblast invasion and migration through affecting the expression of protease, hormones, angiogenic factors, growth factors and cytokines. As the invasive and migratory abilities of trophoblast are essential for successful placentation and fetus development, our findings suggest a potential risk of triazole fungicides to human pregnancy.

Abstract
OBJECTIVE We aimed to compare sFlt-1 and placental growth factor (PlGF) levels and the sFlt-1/PlGF ratio between women with preeclampsia and superimposed preeclampsia to, respectively, normotensive and chronic hypertensive ones. STUDY DESIGN We performed a prospective two-armed cohort in a tertiary teaching hospital in Sao Paulo, Brazil, including 37 normotensive and 60 chronic hypertensive pregnant women. We assessed the serum levels of sFlt-1 and PlGF at 20, 26, 32, and 36 gestational weeks by enzyme-linked immunosorbent assay. MAIN OUTCOME MEASURES Having preeclampsia and superimposed preeclampsia. RESULTS Among normotensive and chronic hypertensive pregnancies, 4 (10.8%) and 14 (23.3%) women developed preeclampsia and superimposed preeclampsia, respectively. Compared with those who remained normotensive, the preeclampsia women presented higher sFlt-1 levels at 32 gestational weeks (4323.45 pg/mL vs. 2242.04 pg/mL, p = 0.019), lower PlGF levels at 20 (183.54 pg/mL vs. 337.38 pg/mL, p = 0.034), 32 (169.69 pg/mL vs. 792.53 pg/mL, p = 0.001), and 36 gestational weeks (252.99 pg/mL vs. 561.81 pg/mL, p = 0.029), and higher sFlt-1/PlGF ratios at 26 (9.02 vs. 1.84, p = 0.004), 32 (23.61 vs. 2.55, p = 0.001), and 36 gestational weeks (49.02 vs. 7.34, p = 0.029). On the other hand, compared with those who remained chronic hypertensive, the superimposed preeclampsia women only presented a higher sFlt-1/PlGF ratio at 32 gestational weeks (9.98 vs. 2.51, p = 0.039). CONCLUSION Although angiogenic imbalance is clearly related to preeclampsia, it seems to play a more modest role in superimposed preeclampsia, in which other mechanisms should also be investigated.

Abstract
The angiogenic factors vascular endothelial growth factor (VEGF) and placental growth factor (PIGF) play a central role in the process of angiogenesis. We evaluated the association of free PIGF and free VEGF levels and the risk of preeclampsia (PE) among Tunisian Arab women, and established the range of VEGF and PIGF in normal healthy pregnancies, between 24 and 42weeks of gestation. This retrospective case-control study included 345 women with PE, and 289 women with uncomplicated pregnancies. PIGF and VEGF plasma levels were quantitated by commercially-available ELISA. Compared to control women, plasma PIGF concentrations were lower in women with PE at all gestation age intervals (P<0.0001), compared to VEGF levels which were significantly lower in women with PE but only during early gestation age intervals ([29-32[ and [32-35[). High odds for developing PE, and correspondingly higher associations, were associated with low PIGF values (less than the 5(th) percentile), at all gestation age intervals. The only exception was recorded for the [29-32 [interval, which was not statistically significant. PIGF testing, recorded at 29-37weeks of gestation, had a higher specificity (93-100%) than sensitivity, and the positive predictive values ranged from 90% to 100% for 24-37weeks of gestation. This indicates that it mainly detects non-PE healthy women as well, and thus may be useful as a screening test, though currently unreliable for diagnostic purposes. Reduced PIGF levels during different gestation age intervals, and reduced VEGF levels during early gestation age intervals are also associated with subsequent development of PE in our population; the gestational age interval adjusted-5(th) percentiles of PIGF provide reference ranges for this marker in normal pregnancy.

Abstract
Remodeling of maternal spiral arteries during pregnancy requires a subpopulation of extravillous cytotrophoblasts (EVTs) to differentiate into endovascular EVTs. Activin A, which is abundantly expressed at the maternal-fetal interface, has been shown to promote trophoblast invasion, but its role in endovascular differentiation remains unknown. Vascular endothelial growth factor-A (VEGF-A) is well recognized as a key regulator in trophoblast endovascular differentiation. Whether and how activin A might regulate VEGF-A production in human trophoblasts and its relationship to endovascular differentiation have yet to be determined. In the present study, we found that activin A increased VEGF-A production in primary and immortalized (HTR8/SVneo) human EVT cells. In addition, activin A enhanced HTR8/SVneo endothelial-like tube formation, and these effects were attenuated by pretreatment with small interfering RNA targeting VEGF-A or the VEGF receptor 1/2 inhibitor SU4312. Pretreatment with the activin/TGF-β type 1 receptor (ALK4/5/7) inhibitor SB431542 abolished the stimulatory effects of activin A on phosphorylated mothers against decapentaplegic (SMAD)-2/3 phosphorylation, VEGF-A production, and endothelial-like tube formation. Moreover, small interfering RNA-mediated down-regulation of SMAD2, SMAD3, or common SMAD4 abolished the effects of activin A on VEGF-A production and endothelial-like tube formation. In conclusion, activin A may promote human trophoblast cell endothelial-like tube formation by up-regulating VEGF-A production in an SMAD2/3-SMAD4-dependent manner. These findings provide insight into the cellular and molecular events regulated by activin A during human implantation.

Abstract
OBJECTIVE The aim of this study evaluate the value of vascular endothelial growth factor (VEGF) and placental growth factor (PGF) serum levels in prediction of preeclampsia, severity and onset time of the disease. METHODS Twenty five placentas of pregnant women diagnosed with preeclampsia (15 severe preeclampsia, 10 mild preeclampsia) and peripheral venous blood samples were collected. The placental and serum levels of VEGF and PGF were measured. RESULTS VEGF level was significantly higher in cases and the optimal cut-off point was calculated as 600.5 to differentiate the cases and the controls, with 64% sensitivity and 100% specificity. There was a significant increase in median serum level of VEGF in severe cases compared to the mild cases and the controls. The optimal cut-off point for VEGF was calculated as 673.5 to differentiate mild and severe cases, with 93.3% sensitivity and 90% specificity. Whereas, PGF was significantly lower in severe cases than that in the mild cases and controls. The optimal cut-off point for PGF was calculated as 16.1 to differentiate mild and severe cases, with 66.7% sensitivity and 100% specificity. CONCLUSION VEGF and PGF may be significant markers in prediction of severity of preeclampsia, and VEGF may also be valuable in prediction of preeclampsia.

Abstract
The aim of the study was to estimate the levels of vascular endothelial growth factor (VEGF) and endothelin-1 (ET-1) in maternal serum from normal pregnant women and women with pre-eclampsia. Serum concentrations of VEGF and ET-1 were measured in maternal blood in control group (n = 40) and in pregnancies complicated by pre-eclampsia (n = 40). Results showed that maternal VEGF levels were significantly raised in women with pre-eclampsia (p < 0.001). ET-1 concentration was not significantly different among women with pre-eclampsia compared with that in the control group. It was concluded that an increase in serum VEGF level was demonstrated in pre-eclampsia, suggesting that VEGF is involved in pathogenesis of pre-eclampsia. Further studies are needed to determine the serum concentrations of VEGF in pregnant women before the development of pre-eclampsia.

Abstract
The maternal and fetal toxicity of benzyl benzoate, commonly used as antiparasitic insecticide, was evaluated in pregnant rats after a daily oral dose of 25 and 100 mg/kg. Biochemical, histopathological, and morphological examinations were performed. Dams were observed for maternal body weights and food and water consumption and subjected to caesarean section on (GD) 20. Maternal and fetal liver, kidney, heart, brain, and placenta were examined histopathologically under light microscope. Maternal and fetal liver and placenta were stained immunohistochemically for vascular endothelial growth factor (VEGF). Morphometric analysis of fetal body lengths, placental measurements, and fetal skeletal stainings was performed. Statistically significant alterations in biochemical parameters and placental and skeletal measurements were determined in treatment groups. In addition to histopathological changes, considerable differences were observed in the immunolocalization of VEGF in treatment groups. These results demonstrated that benzyl benzoate and its metabolites can transport to the placenta and eventually enter the fetuses.

Abstract
Comparative morphological study of the placentas from women with pre-eclampsia of different severity was carried out. The expression of vascular endothelial growth factor and its receptors (VEGFR-1, VEGFR-2, VEGFR-3) was studied by immunohistochemical methods. Branched angiogenesis processes predominated in the placentas of patients with pre-eclampsia. The syncytiocapillary membranes were thickened, the number of syncytial buds was greater than normally. Immunohistochemical studies showed high expression of VEGF and VEGFR-1 and low expression of VEGFR-2 in the placental villous structures.

Abstract
BACKGROUND Emerging evidence showed that VEGF gene polymorphisms are involved in the regulation of VEGF protein expression, thus increasing an individual's susceptibility to preeclampsia (PE); but individually published results are inconclusive. The aim of this meta-analysis was to investigate the associations between VEGF gene polymorphisms and PE risk. METHODS A systematic literature search of MEDLINE, Embase, Web of Science, and CNKI (Chinese National Knowledge Infrastructure) databases was conducted. Statistical analyses were performed using STATA 12.0 software and Review manager 5.1. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of associations. RESULTS According to the inclusion criteria, 11 case-control studies were finally included in this meta-analysis. A total of 1,069 PE cases and 1,315 controls were included in this study. Our meta-analysis indicated that VEGF +936C/T (T vs. C, OR = 1.52, 95%CI = 1.08-2.12) or -634G/C polymorphism (C vs. G, OR = 1.24, 95% CI = 1.03-1.50) was associated with the risk of PE, whereas there was no association between -2578C/A (A vs. C, OR = 0.98, 95%CI = 0.82-1.16) or -1154G/A (A vs. G, OR = 1.30, 95%CI = 0.94-1.78) polymorphism and PE risk in our study. CONCLUSION Our meta-analysis suggested that VEGF -2578C/A or -1154G/A polymorphism had no association with PE risk in all examined patients, whereas there was an association between VEGF +936C/T or -634G/C polymorphism and risk of PE.

Abstract
BACKGROUND Whether hypertensive disorders in pregnancy (HDP) are the risk factors of bronchopulmonary dysplasia (BPD) is controversial. A systematic review was made to determine the association between HDP and BPD in preterm infants. METHODS We searched PubMed, Embase, Cochrane Library, ScienceDirect, Web of Science, with no language limitation, and reviewed the reference lists of the selected articles to identify additional relevant publications and contacted the authors of relevant studies for further information. The data were extracted independently by 2 reviewers who used a predetermined data extraction form. Studies were combined with an odds ratio (OR) using a random-effects model. Meta-regression and subgroup analysis were used to explore potential confounders. Funnel plots, Egger's test and Begg's test were used to investigate the publication bias. The Trim and Fill method was used to control the publication bias. RESULTS A total of 787 studies were identified and only 15 studies (20 779 patients) were included. The pooled unadjusted OR showed that HDP was significantly associated with BPD (P=0.04; OR=1.29, 95% CI=1.01-1.65). Heterogeneity was substantial (I(2)=74%) and might be partially explained by different variables in maternal complications between the control groups across the studies. The pooled adjusted OR suggested the same conclusion that HDP was a risk factor for BPD (P=0.01; OR=1.59, 95% CI=1.11-2.26). Funnel plot and Egger's test showed that there were publication bias of unadjusted estimate of association between HDP and BPD. CONCLUSIONS Unadjusted analyses showed that the rate of BPD was slightly higher in the infants exposed to HDP, and adjusted analyses confirmed this finding. But this result should be interpreted cautiously because substantial heterogeneity and publication bias were identified in this review.

Abstract
BACKGROUND Hypertensive disorders of pregnancy and intrauterine growth restriction (IUGR) are leading causes of maternal and perinatal morbidity and mortality. Failure to detect intrauterine growth restriction in women at high risk has been highlighted as a significant avoidable cause of serious fetal outcome. In this observational study we compare fetal flow using Doppler ultrasonography with a new test for placental growth factor (PlGF) to predict fetal adverse events. METHODS Eighty-nine women with hypertensive disorders of pregnancy (24 with chronic hypertension, 17 with gestational hypertension, 12 with HELLP syndrome, 19 with preeclampsia and 17 with superimposed preeclampsia) were enrolled. A single maternal blood sample to measure free PlGF (Alere Triage) taken before 35 weeks of pregnancy was compared to the last Doppler ultrasound measurement of fetal flow before delivery. PlGF was classified as normal (PlGF≥100 pg/ml), low (12<PlGF<100) or very low (PlGF≤12 pg/ml). A positive test for abnormal fetal flow was defined as either signs of centralisation of the fetal circulation or diastolic block or reverse flow in the umbilical artery or descending aorta; this was a criterion for delivery. Fetal outcomes were intrauterine growth restriction and birth before 37 weeks of pregnancy. RESULTS In total 61/89 women had a preterm birth and 22 infants had IUGR. Of those who delivered preterm, 20/20 women with abnormal fetal flow and 36/41 (87.8%) women with normal fetal flow had low or very low PlGF. Of those infants with IUGR, 22/22 had low or very low maternal PlGF and 10/22 had abnormal fetal flow. CONCLUSIONS PlGF may provide useful information before 35th gestational week to identify fetuses requiring urgent delivery, and those at risk of later adverse outcomes not identified by fetal flow Doppler ultrasonography.

Abstract
UNLABELLED The objective of the present study was to evaluate whether placental mesenchymal stromal cells (PDMSCs) derived from normal and preeclamptic (PE) chorionic villous tissue presented differences in their cytokines expression profiles. Moreover, we investigated the effects of conditioned media from normal and PE-PDMSCs on the expression of pro-inflammatory Macrophage migration Inhibitory Factor (MIF), Vascular Endothelial Growth Factor (VEGF), soluble FMS-like tyrosine kinase-1 (sFlt-1) and free β-human Chorionic Gonadotropin (βhCG) by normal term villous explants. This information will help to understand whether anomalies in PE-PDMSCs could cause or contribute to the anomalies typical of preeclampsia. METHODS Chorionic villous PDMSCs were isolated from severe preeclamptic (n = 12) and physiological control term (n = 12) placentae. Control and PE-PDMSCs's cytokines expression profiles were determined by Cytokine Array. Control and PE-PDMSCs were plated for 72 h and conditioned media (CM) was collected. Physiological villous explants (n = 48) were treated with control or PE-PDMSCs CM for 72 h and processed for mRNA and protein isolation. MIF, VEGF and sFlt-1 mRNA and protein expression were analyzed by Real Time PCR and Western Blot respectively. Free βhCG was assessed by immunofluorescent. RESULTS Cytokine array showed increased release of pro-inflammatory cytokines by PE relative to control PDMSCs. Physiological explants treated with PE-PDMSCs CM showed significantly increased MIF and sFlt-1 expression relative to untreated and control PDMSCs CM explants. Interestingly, both control and PE-PDMSCs media induced VEGF mRNA increase while only normal PDMSCs media promoted VEGF protein accumulation. PE-PDMSCs CM explants released significantly increased amounts of free βhCG relative to normal PDMSCs CM ones. CONCLUSIONS Herein, we reported elevated production of pro-inflammatory cytokines by PE-PDMSCs. Importantly, PE PDMSCs induced a PE-like phenotype in physiological villous explants. Our data clearly depict chorionic mesenchymal stromal cells as central players in placental physiopathology, thus opening to new intriguing perspectives for the treatment of human placental-related disorders as preeclampsia.
