Cells 2024; 13:1534. [PMID: 39329718 PMCID: PMC11430553 DOI: 10.3390/cells13181534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2024] [Revised: 09/07/2024] [Accepted: 09/10/2024] [Indexed: 09/28/2024] Open
Abstract
There are no effective therapies to prevent preeclampsia (PE). Pravastatin shows promise by attenuating processes associated with PE such as decreased cytotrophoblast (CTB) migration, aberrant angiogenesis, and increased oxidative stress. This study assesses the effects of pravastatin on hyperglycemia-induced CTB dysfunction. METHODS Human CTB cells were treated with 100, 150, 200, 300, or 400 mg/dL glucose for 48 h. Some cells were pretreated with pravastatin (1 µg/mL), while others were cotreated with pravastatin and glucose. The expression of urokinase plasminogen activator (uPA), plasminogen activator inhibitor 1 (PAI-1) mRNA, vascular endothelial growth factor (VEGF), placenta growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1), and soluble endoglin (sEng) were measured. CTB migration was assayed using a CytoSelect migration assay kit. Statistical comparisons were performed using an analysis of variance with Duncan's post hoc test. RESULTS The hyperglycemia-induced downregulation of uPA was attenuated in CTB cells pretreated with pravastatin at glucose levels > 200 mg/dL and cotreated at glucose levels > 300 mg/dL (p < 0.05). Hyperglycemia-induced decreases in VEGF and PlGF and increases in sEng and sFlt-1 were attenuated in both the pretreatment and cotreatment samples regardless of glucose dose (p < 0.05). Pravastatin attenuated hyperglycemia-induced dysfunction of CTB migration. CONCLUSIONS Pravastatin mitigates stress signaling responses in hyperglycemic conditions, weakening processes leading to abnormal CTB migration and invasion associated with PE in pregnancy.

Detection of Urinary Misfolded Proteins for Imminent Prediction of Preeclampsia in Pregnant Women With Suspected Cases: Protocol for a Prospective Noninterventional Study. JMIR Res Protoc 2024; 13:e54026. [PMID: 38669061 PMCID: PMC11087858 DOI: 10.2196/54026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 03/19/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Preeclampsia (PE) is one of the most common hypertensive diseases, affecting 2%-8% of all pregnancies. The high maternal and fetal mortality rates of PE are due to a lack of early identification of affected pregnant women that would have led to closer monitoring and care. Recent data suggest that misfolded proteins might be a promising biomarker for PE prediction, which can be detected in urine samples of pregnant women according to their congophilia (aggregated) characteristic. OBJECTIVE The main purpose of this trial is to evaluate the value of the urine congophilia-based detection of misfolded proteins for the imminent prediction of PE in women presenting with suspected PE. The secondary objectives are to demonstrate that the presence of urine misfolded proteins correlates with PE-related maternal or neonatal adverse outcomes, and to establish an accurate PE prediction model by combining misfolded proteins with multiple indicators. METHODS At least 300 pregnant women with clinical suspicion of PE will be enrolled in this prospective cohort study. Participants should meet the following inclusion criteria in addition to a suspicion of PE: ≥18 years old, gestational week between 20+0 and 33+6, and single pregnancy. Consecutive urine samples will be collected, blinded, and tested for misfolded proteins and other PE-related biomarkers at enrollment and at 4 follow-up visits. Clinical assessments of PE status and related complications for all participants will be performed at regular intervals using strict diagnostic criteria. Investigators and participants will remain blinded to the results. Follow-up will be performed until 42 days postpartum. Data from medical records, including maternal and fetal outcomes, will be collected. The performance of urine misfolded proteins alone and combined with other biomarkers or clinical variables for the prediction of PE will be statistically analyzed. RESULTS Enrollment started in July 2023 and was still open upon manuscript submission. As of March 2024, a total of 251 eligible women have been enrolled in the study and enrollment is expected to continue until August 2024. Results analysis is scheduled to start after all participants reach the follow-up endpoint and complete clinical data are collected. CONCLUSIONS Upon completion of the study, we expect to derive an accurate PE prediction model, which will allow for proactive management of pregnant women with clinical suspicion of PE and possibly reduce the associated adverse pregnancy outcomes. The additional prognostic value of misfolded proteins is also expected to be confirmed.

Abstract
Pre-eclampsia (PE) is a placenta-mediated disease and remains a major cause of maternal and neonatal mortality and morbidity. As PE develops, normal pregnancy's hypercoagulable balance is disrupted, leading to platelet hyperactivation, excessive pathological hypercoagulability, and perturbed fibrinolysis. This narrative review aims to summarize the current knowledge regarding hemostasis in PE compared with healthy gestation and the potential effects of maternal PE on neonatal hemostasis. Finally, it aims to discuss hemostasis assessments for normal pregnancies and PE, emphasizing the role of viscoelastic tests, namely, thromboelastography (TEG) and thromboelastometry (ROTEM), for monitoring PE-associated hemostatic alterations. The use of TEG/ROTEM for assessing the hemostatic profile of PE women has been little considered, even though conventional coagulation tests (CCTs) have not helped to monitor hemostasis in this population. Compared with normal pregnancy, TEG/ROTEM in PE reveals an excessive hypercoagulability analogous with the severity of the disease, characterized by higher-stability fibrin clots. The TEG/ROTEM parameters can reflect PE severity and may be used for monitoring and as predictive markers for the disease.

Abstract
BACKGROUND Preeclampsia (PE) is a serious pregnancy complication, resulting in potentially life-threatening conditions for both mother and foetus. It is worth noting that early-onset PE has become a great challenge for clinicians due to its complex manifestation, rapid progression and serious complications. This study aims to investigate differential serum proteome profiles in patients with early-onset PE. METHODS Each serum sample was separated using a nanoliter flow rate Easy-nLC chromatography system. Then the samples were analysed by mass spectrometry. Bioinformatics analyses were conducted to analyse the functional categories or signal transduction pathways for differentially abundant proteins. Key proteins identified by mass spectrometry were verified by ELISA. RESULTS We found 30 and 34 proteins were upregulated and downregulated in early-onset PE patients (n = 3) vs controls (n = 3), respectively. Functional enrichment analysis revealed differentially expressed proteins related to the immune response and regulation of peptidase activity. ELISA confirmed that there were lower CSH1 levels and higher LPA concentrations in the serum samples of early-onset PE patients (n = 22) than in healthy controls (n = 19) (p < 0.05 for CSH1 and p < 0.001 for LPA). CONCLUSIONS This study revealed the critical features of serum proteins in early-onset PE patients. LPA and CSH1 may serve as biomarkers for early-onset PE diagnosis and therapy.

Abstract
BACKGROUND Preeclampsia (PE), a pregnancy specific syndrome, is one kind of common gestational hypertension disease, which can cause maternal and perinatal mortality and morbidity. This study was conducted to identify key microRNAs (miRNAs), mRNAs and related signaling pathways in the pathogenesis of PE. METHODS Whole transcriptome sequencing and small RNA sequencing of the peripheral blood from 3 PE patients and 3 normal pregnant women were performed. Differential expressed (DE) miRNAs were identified using the DEseq2 package. Target genes of the selected upregulated and downregulated DE miRNAs were predicted. Based on the hypergeometric distribution of DE miRNA target genes, we analyzed GO enrichment and KEGG pathway enrichment using R. RESULTS Total 1291 and 1281 novel RNAs were obtained from the preeclampsia patients and healthy individuals. 70 miRNAs were screened out with significant levels with 51 significantly upregulated and 19 significantly downregulated. 44,306 genes were predicted as the targets of these miRNAs. Besides, KEGG pathway analysis revealed that the upregulated miRNAs were enriched in Glycosaminoglycan biosynthesis-chondroitin sulfate / dermatan sulfate, Base excision repair and the downregulated miRNAs were enriched in Tuberculosis, Phagosome. CONCLUSION We constructed regulatory networks of miRNAs and target genes, there were 2208 negative miRNA-mRNA interactions in total. The network and pathway information illustrate the potential functions of mRNAs and miRNAs in PE pathogenesis.

Abstract
OBJECTIVES The objective of this study was to identify the predictive value of the first-trimester serum SHARP1 level and the second-trimester uterine artery Doppler in singleton pregnancy for the prediction of preeclampsia. METHODS A prospective study including singleton pregnancy presenting at an antenatal clinic, King Chulalongkorn Memorial Hospital, Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University from 2019-March 2020 was conducted. Serum SHARP1 was collected at the gestational age (GA) of 11-13+6 weeks, and transabdominal uterine artery Doppler ultrasound was performed at GA of 18-24 weeks. Serum SHARP1 level and uterine artery pulsatility index (PI) were combined to calculate the predictive value for preeclampsia detection. RESULTS 288 pregnant women were enrolled in the first trimester, but only 249 participants completed the study. Thirteen patients had preeclampsia (5.2%), which three cases (1.2%) had early-onset preeclampsia. The median serum SHARP1 level in the first trimester of pregnant women with preeclampsia was lower than the normal pregnancy group (1392 pg/ml vs. 1941 pg/ml, p = 0.046). The second-trimester uterine artery PI and prevalence of early diastolic notching were higher in the preeclampsia group than in the normal pregnancy group (p = 0.029 and p = 0.001, respectively). When the first-trimester serum SHARP1 level is combined with the second-trimester uterine artery PI, the sensitivity, specificity, PPV, and NPV for preeclampsia prediction were 84.6%, 47.5%, 8.2%, and 98.3%, respectively. CONCLUSIONS This study demonstrated that serum SHARP1 level in the first trimester combined with the uterine artery PI in the second trimester had good sensitivity to predict preeclampsia.

Abstract
Early-onset preeclampsia (EOPE) is a severe pregnancy complication associated with defective trophoblast differentiation and functions at implantation, but manifestation of its phenotypes is in late pregnancy. There is no reliable method for early prediction and treatment of EOPE. Adrenomedullin (ADM) is an abundant placental peptide in early pregnancy. Integrated single-cell sequencing and spatial transcriptomics confirm a high ADM expression in the human villous cytotrophoblast and syncytiotrophoblast. The levels of ADM in chorionic villi and serum were lower in first-trimester pregnant women who later developed EOPE than those with normotensive pregnancy. ADM stimulates differentiation of trophoblast stem cells and trophoblast organoids in vitro. In pregnant mice, placenta-specific ADM suppression led to EOPE-like phenotypes. The EOPE-like phenotypes in a mouse PE model were reduced by a placenta-specific nanoparticle-based forced expression of ADM. Our study reveals the roles of trophoblastic ADM in placental development, EOPE pathogenesis, and its potential clinical uses.

J Physiol 2023; 601:3631-3645. [PMID: 37401732 PMCID: PMC10807859 DOI: 10.1113/jp284746] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 06/19/2023] [Indexed: 07/05/2023] Open
Abstract
Preeclampsia (PE) differentially impairs female and male fetal endothelial cell function, which is associated with an increased risk of adult-onset cardiovascular disorders in children born to mothers with PE. However, the underlying mechanisms are poorly defined. We hypothesize that dysregulation of microRNA-29a-3p and 29c-3p (miR-29a/c-3p) in PE disturbs gene expression and cellular responses to cytokines in fetal endothelial cells in a fetal sex-dependent manner. RT-qPCR analysis of miR-29a/c-3p was performed on female and male unpassaged (P0) human umbilical vein endothelial cells (HUVECs) from normotensive (NT) pregnancies and PE. Bioinformatic analysis of an RNA-seq dataset was performed to identify PE-dysregulated miR-29a/c-3p target genes in female and male P0-HUVECs. Gain- and loss-of-function assays were conducted to determine the effects of miR-29a/c-3p on endothelial monolayer integrity and proliferation in response to transforming growth factor-β1 (TGFβ1) and tumour necrosis factor-α (TNFα) in NT and PE HUVECs at passage 1. We observed that PE downregulated miR-29a/c-3p in male and female P0-HUVECs. PE dysregulated significantly more miR-29a/c-3p target genes in female vs. male P0-HUVECs. Many of these PE-differentially dysregulated miR-29a/c-3p target genes are associated with critical cardiovascular diseases and endothelial function. We further demonstrated that miR-29a/c-3p knockdown specifically recovered the PE-abolished TGFβ1-induced strengthening of endothelial monolayer integrity in female HUVECs, while miR-29a/c-3p overexpression specifically enhanced the TNFα-promoted cell proliferation in male PE HUVECs. In conclusion, PE downregulates miR-29a/c-3p expression and differentially dysregulates miR-29a/c-3p target genes associated with cardiovascular diseases and endothelial function in female and male fetal endothelial cells, possibly contributing to the fetal sex-specific endothelial dysfunction observed in PE. KEY POINTS: Preeclampsia differentially impairs female and male fetal endothelial cell function in responses to cytokines. Pro-inflammatory cytokines are elevated in maternal circulation during pregnancy in preeclampsia. MicroRNAs are critical regulators of endothelial cell function during pregnancy. We have previously reported that preeclampsia downregulated microRNA-29a-3p and 29c-3p (miR-29a/c-3p) in primary fetal endothelial cells. However, it is unknown if PE differentially dysregulates the expression of miR-29a/c-3p in female and male fetal endothelial cells. We show that preeclampsia downregulates miR-29a/c-3p in male and female HUVECs and preeclampsia dysregulates cardiovascular disease- and endothelial function-associated miR-29a/c-3p target genes in HUVECs in a fetal sex-specific manner. MiR-29a/c-3p differentially mediate cell responses to cytokines in female and male fetal endothelial cells from preeclampsia. We have revealed fetal sex-specific dysregulation of miR-29a/c-3p target genes in fetal endothelial cells from preeclampsia. This differential dysregulation may contribute to fetal sex-specific endothelial dysfunction in offspring born to preeclamptic mothers.

The endocannabinoidome in human placenta: Possible contribution to the pathogenesis of preeclampsia. Biofactors 2023; 49:887-899. [PMID: 37092955 DOI: 10.1002/biof.1952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 03/31/2023] [Indexed: 04/25/2023]
Abstract
Preeclampsia (PE) was first reported thousands of years ago, yet there is still a shortage of biomarkers to determine the severity and type of PE. The importance of the expanded endocannabinoid system, or endocannabinoidome (eCBome), has emerged recently in placental physiology and pathology, though the potential alterations of the eCBome in PE have not been fully explored. Analysis by qRT-PCR using placental samples of normotensive and PE women demonstrate for the first time the presence of ABHD4, GDE1, and DAGLβ in both normotensive and PE placental tissues. Interestingly, NAPE-PLD, FAAH-1, DAGLα, MAGL, and ABHD6 mRNA levels were increased in the placental tissues of PE patients. Quantification in plasma and placental tissues showed a decrease for anandamide (AEA), N-oleoylethanolamine (OEA), and N-docosahexaenoylethanolamine (DHEA) in the placenta, accompanied only by a decrease in plasma levels of AEA. In addition, a strong negative correlation was obtained between OEA and the biomarker of PE, soluble fms-like tyrosine kinase-1. Given the inflammatory nature of PE and the anti-inflammatory role of OEA and DHEA, the decrease in the local levels of these mediators may underlie the inflammatory component of this pathology. Additionally, lower AEA levels in both placenta and plasma may contribute to the atypical alterations of the spiral arteries in PE due to the vasorelaxation effects of AEA. These results add new information to the role of the eCBome members in placental development, while also pointing to a potential role as biomarkers of PE.

Abstract
Background Preeclampsia (PreE), the de novo onset of hypertension and proteinuria at 20 weeks of gestation, is a leading cause of maternal and fetal morbidity and mortality. This study compared inflammatory biomarkers in PreE and normal pregnancies using paired samples of mothers and neonates. Methods Twenty normal pregnant and 27 PreE patients were monitored for biomarkers, neonatal outcomes, and placental morphologies. Fetal and maternal serum levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble endoglin (sENG), and soluble fms-like tyrosine kinase-1 (sFLT-1) were measured by enzyme-linked immunosorbent assay. Results Placental thickness was 25 mm in early PreE subjects compared to 32 mm in late PreE subjects (P < 0.05). Placental volume was 296 cm3 in early PreE compared to 393 cm3 in late PreE (P < 0.05). The average hospital stay for PreE babies was longer (20 ± 5 days) compared to babies from normal pregnancies (2 ± 1 days; P < 0.05). PreE babies had a lower Ponderal index (2.28 ± 0.3) than those from normal pregnancies (2.95 ± 0.2; P < 0.05). sENG and sFLT-1 had cord values like the maternal values, while VEGF and PlGF did not. Conclusion PreE alters the intrauterine environment by activating chemical mediators that result in maternal and fetal complications.

Abstract
INTRODUCTION Pregnancy complications, as preeclampsia (PE) and HELLP syndrome, occurring with similar pathophysiological mechanisms, have adverse effects on the health of both mother and fetus during pregnancy and thereafter, they are leading causes of maternal and fetal morbidity and mortality. The hair metabolome has been recognized as a valuable source of information in pregnancy research, as it provides stable metabolite information to be able to assist with studying biomarkers or metabolic mechanisms of pregnancy and its complications. OBJECTIVE The aim of this study was to investigate the hair metabolome profile of pregnant women with PE, HELLP syndrome and healthy women. METHOD Hair samples of new-borns' mothers (patients and controls) were investigated segmentally relevant to each trimester using a proper sample preparation and gas chromatography-mass spectrometry (GC-MS) to identify robust biomarkers that can be useful for screening, early detection, follow-up and treatment of PE and HELLP syndrome, the etiology of which are still unknown. RESULTS The results showed a significant change in the metabolome profiles of the patient and control groups regarding the trimesters. A striking decrease was observed in all 100 metabolites investigated in the patient group (p < 0.000). The metabolic pathways associated with significant metabolites have also been investigated, and the most affected pathways were observed to be the urea cycle, glycine, serine, aspartate, methionine and purine metabolism, ammonia cycle, and phosphatidylethanolamine biosynthesis. CONCLUSION The found metabolites provide us with extensive data on the ability to establish biomarkers for predicting, early detection and monitoring of PE.

Abstract
OBJECTIVE The aim of this study was to examine the diagnostic value of ophthalmic artery Doppler indices in predicting preeclampsia along with other markers in the third trimester of pregnancy. METHODS Normotensive pregnancies were included during 28-32 weeks of gestation to undergo uterine and ophthalmic artery Doppler ultrasound. Maternal and fetal characteristics were documented at the visit between the 28 and 32 weeks of gestation, and pregnancy-associated plasma protein A (PAPP-A) values in the first trimester were collected to be integrated into a multiparametric prediction model. RESULTS Of 795 included participants, 48 cases progressed to preeclampsia. All assessed ophthalmic Doppler parameters including first and second peak systolic velocities (PSVs), second to first peak ratio (PR), and pulsatility index (PI), were statistically different in patients who developed preeclampsia later on. The average PR (sensitivity: 100% [95% CI, 0.81-1.00]; specificity: 90% [95% CI, 0.86-0.93]) and PI between the eyes, PAPP-A multiple of median and uterine artery PI were determined to be the most important predictors of PE, which were subsequently integrated into a multiple regression model (sensitivity: 94% [95% CI, 0.70-1.00]; specificity: 93% [95% CI, 0.89-0.96]). CONCLUSION This study provided a screening method for individuals at higher risk of progressing to preeclampsia in the third trimester of pregnancy.

Prevalence, maternal characteristics, and birth outcomes of preeclampsia: A cross-sectional study in a single tertiary healthcare center in greater Kuala Lumpur Malaysia. Front Public Health 2022; 10:973271. [PMID: 36324467 PMCID: PMC9618654 DOI: 10.3389/fpubh.2022.973271] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 09/30/2022] [Indexed: 01/25/2023] Open
Abstract
Background Preeclampsia is associated with an increased risk of adverse maternal and perinatal outcomes. This study aimed to assess preeclampsia prevalence in a Malaysian referral maternity hospital and the association between preeclampsia and maternal characteristics and outcomes. Methods A cross-sectional study was conducted between January 2010 and December 2020 using secondary data from a single tertiary healthcare center in Greater Kuala Lumpur, Malaysia. A total of 40,212 deliveries were included for analysis to investigate the association between conditions (maternal characteristics and adverse birth outcomes) and preeclampsia. Multivariable logistic regression was conducted to assess the association between multiple independent variables and the outcome variable (preeclampsia). Results The reported prevalence of preeclampsia was 1.6%. Pregnant women with preeclampsia had a higher risk of preterm delivery (67.7%), instrumental and cesarean delivery (74.7%), neonatal low birth weight (48.5%), neonatal 5-min Apgar score <7 (18.1%), and neonatal intensive care unit (NICU) admission (19.8%). There were significantly higher odds of developing preeclampsia among nullipara [adjusted odd ratio (adjOR) 1.792, 95% CI: 1.518-2.115], women with a previous history of preeclampsia (adjOR 5.345, 95% CI: 2.670-10.698) and women with multiple pregnancies (adjOR 1.658, 95% CI: 1.071-2.566). However, there is a significant association between maternal characteristic variables. There was a significant association when a combination of variables for risk assessment: the presence of anemia and gestational hypertension effect on preeclampsia (OR 26.344, 95% CI: 9.775-70.993, p < 0.002) and gestational hypertension without anemia on preeclampsia (OR 3.084, 95% CI: 2.240-4.245, p < 0.001). Similarly, an association was seen between chronic hypertension and younger age (<35 years old) on preeclampsia (OR 14.490, 95% CI: 9.988-21.021, p < 0.001), and having chronic hypertension with advanced maternal age (≥35 years old) on preeclampsia (OR 5.174, 95% CI: 3.267-8.195, p < 0.001). Both conditions had increased odds of preeclampsia, in varying magnitudes. Overall, the significant interaction effects suggest that a history of chronic or gestational hypertension has a different relationship to the incidence of preeclampsia depending on the maternal age and anemia status. Pregnant women with preeclampsia had significantly higher odds for preterm delivery (adjOR 6.214, 95% CI: 5.244-7.364), instrumental and cesarean delivery (adjOR 4.320, 95% CI: 3.587-5.202), neonatal low birth weight (adjOR 7.873, 95% CI: 6.687-9.271), 5-min Apgar score <7 (adjOR 3.158, 95% CI: 2.130-4.683), and NICU admission (adjOR 8.778, 95% CI: 7.115-10.830). Conclusions Nulliparity, previous history of preeclampsia, and multiple pregnancies were associated with an increased risk of preeclampsia. The presence of different underlying conditions, such as chronic hypertension, anemia, and extremes of maternal age played an important role in increasing preeclampsia risk in the considered study. Larger samples are needed to validate such findings.

Primary Human Trophoblasts Mimic the Preeclampsia Phenotype after Acute Hypoxia-Reoxygenation Insult. Cells 2022; 11:cells11121898.

Abstract
Preeclampsia (PE) is a pregnancy-specific disorder that affects 3 to 5% of pregnancies worldwide and is one of the leading causes of maternal and fetal morbidity and mortality. Nevertheless, how these events occur remains unclear. We hypothesized that the induction of hypoxic conditions in vitro in primary human trophoblast cells would mimic several characteristics of PE found in vivo. We applied and characterized a model of primary cytotrophoblasts isolated from healthy pregnancies that were placed under different oxygen concentrations: ambient O2 (5% pCO2, 21%pO2, 24 h, termed “normoxia”), low O2 concentration (5% pCO2, 1.5% pO2, 24 h, termed “hypoxia”), or “hypoxia/reoxygenation” (H/R: 6 h intervals of normoxia and hypoxia for 24 h). Various established preeclamptic markers were assessed in this cell model and compared to placental tissues obtained from PE pregnancies. Seventeen PE markers were analyzed by qPCR, and the protein secretion of soluble fms-like tyrosine kinase 1 (sFlT-1) and the placenta growth factor (PlGF) was determined by ELISA. Thirteen of seventeen genes associated with angiogenesis, the renin–angiotensin system, oxidative stress, endoplasmic reticulum stress, and the inflammasome complex were susceptible to H/R and hypoxia, mimicking the expression pattern of PE tissue. In cell culture supernatants, the secretion of sFlT-1 was increased in hypoxia, while PlGF release was significantly reduced in H/R and hypoxia. In the supernatants of our cell models, the sFlT-1/PlGF ratio in hypoxia and H/R was higher than 38, which is a strong indicator for PE in clinical practice. These results suggest that our cellular models reflect important pathological processes occurring in PE and are therefore suitable as PE in vitro models.

Abstract
OBJECTIVE FOXP3 single nucleotide polymorphisms (SNPs) were recently elucidated to influence the development of preeclampsia (PE), but the results on this issue still remained controversial. Thus, a meta-analysis was implemented to systematically investigate the roles of FOXP3 SNPs in PE. METHODS Eligible publications were identified by retrieving relevant electronic databases. Meanwhile, the association intensity was estimated by calculating odds ratios (ORs) and 95% confidence intervals (CIs) in various genetic models. RESULTS Totally eight investigations involving 3446 subjects were enrolled in the final meta-analysis. The AC and AC + CC genotypes of FOXP3 rs3761548 were related to the susceptibility of PE in over-dominant (OR = 1.19, 95%CI = 1.02-1.38, P = 0.03) and recessive (OR = 0.59, 95% CI: 0.36-0.97, P = 0.04) models. Furthermore, correlation between rs2232365 and PE was observed in recessive model (GG vs. GA + AA) (OR = 0.79, 95%CI: 0.65-0.97, P = 0.03). Moreover, rs2232365 GA and GG + GA genotypes were associated with the severity of PE. However, rs4824747, rs3761547 and rs2280883 polymorphisms had no significant impact on PE susceptibility. CONCLUSIONS FOXP3 rs3761548 and rs2232365 SNPs influenced the PE susceptibility and therefore may be potential biomarkers for prediction of PE risk.

Abstract
Melatonin, an indolamine mainly released from the pineal gland, is associated with many biological functions, namely, the modulation of circadian and seasonal rhythms, sleep inducer, regulator of energy metabolism, antioxidant, and anticarcinogenic. Although several pieces of evidence also recognize the influence of melatonin in the reproductive physiology, the crosstalk between melatonin and sex hormones is not clear. Here, we review the effects of sex differences in the circulating levels of melatonin and update the current knowledge on the link between sex hormones and melatonin. Furthermore, we explore the effects of melatonin on gonadal steroidogenesis and hormonal control in females. The literature review shows that despite the strong evidence that sex differences impact on the circadian profiles of melatonin, reports are still considerably ambiguous, and these differences may arise from several factors, like the use of contraceptive pills, hormonal status, and sleep deprivation. Furthermore, there has been an inconclusive debate about the characteristics of the reciprocal relationship between melatonin and reproductive hormones. In this regard, there is evidence for the role of melatonin in gonadal steroidogenesis brought about by research that shows that melatonin affects multiple transduction pathways that modulate Sertoli cell physiology and consequently spermatogenesis, and also estrogen and progesterone production. From the outcome of our research, it is possible to conclude that understanding the correlation between melatonin and reproductive hormones is crucial for the correction of several complications occurring during pregnancy, like preeclampsia, and for the control of climacteric symptoms.

Abstract
Pre-eclampsia is a leading cause of neonatal and maternal mortality and morbidity that complicates approximately 2-8% of all pregnancies worldwide. The precise cause of pre-eclampsia is not completely understood, with several environmental, genetic, and maternal factors involved in its pathogenesis and pathophysiology. An accurate predictor of pre-eclampsia will facilitate early recognition, close surveillance according to the individual risk and early intervention, and reduce the negative consequences of the disorder. Current evidence shows that no single test predicts pre-eclampsia with sufficient accuracy to be clinically useful. A combination of markers into multiparametric models may provide a more useful and feasible predictive tool for pre-eclampsia screening in the routine care setting than a test of either component alone. This review presents a summary of the current advances on prediction of pre-eclampsia, highlighting their performance and applicability. Key priorities when conducting research on predicting pre-eclampsia are also analyzed.

INTRODUCTION Preeclampsia (PE) affects 2-8% of pregnancies and is one of the main causes of maternal morbidity and mortality worldwide. Early identification of pregnant women at higher risk for PE would allow the use of interventions to reduce adverse maternal and perinatal outcomes. OBJECTIVE To assess the ability of bioelectrical impedance analysis (BIA) in pregnancy to predict the development of PE. METHODS This prospective cohort involved healthy nulliparas who underwent BIA at 17-20 weekś gestation and were followed until delivery. We used univariate and multivariate logistic regression to assess the ability of BIA measures to predict the occurrence of PE. We used an adjusted regression model to estimate the probability of developing PE, the Hosmer-Lemeshow test to assess the adequacy of the final model, and ROC curves to assess the sensitivity and specificity of different BIA measures in the prediction of PE. RESULTS Twelve (6.1%) of the 196 participants developed PE. In the final multivariate model, the following BIA measures were associated with the occurrence of PE: extracellular water/intracellular water ≤ 0.618, skeletal muscle mass ≥ 25 Kg, and body fat percentage ≥ 44%. The combination of these three measures had a predictive accuracy of 83.7%, a sensitivity of 83.3%, a specificity of 83.7%, and a negative predictive value of 98.7% for PE. CONCLUSION BIA done on nulliparous women at 17-20 weekś gestation has a good accuracy and high negative predictive value for the risk of developing PE.

Abstract
OBJECTIVE To describe and compare the placental growth factor levels at first trimester in patients that developed preeclampsia, gestational hypertension, IUGR and in those patients without impaired placentation diseases. METHODS Observational study based on a prospective cohort of 422 pregnant women. PlGF values were compared between the different groups (preeclampsia, intrauterine growth restriction (IUGR), gestational hypertension or normal group-patients without impaired placentation diseases). RESULTS The 85.3% (n = 360, 95% CI = 81.9-88.7) had a normal pregnancy, 7.6% (n = 32, 95% CI = 5.1-10.1) had preeclampsia, 3.8% (n = 16, 95% CI = 2.0-5.6) had IUGR and 3.3% (n = 14, 95% CI = 1.6-5.0) had gestational hypertension. The median level of PlGF for preeclampsia (0.76) and IUGR (0.75) were lower than gestational hypertension (0.82) and normal group (1.02). The groups of preeclampsia >34 weeks (0.76), preeclampsia <37 weeks (0.73), and preeclampsia ≥37 weeks (0.77), were significantly lower than the normal group. The sensitivity and specificity of PlGF for impaired placentation diseases is 65% and 64.9%, respectively. CONCLUSION It was found in this study that PlGF has significantly lower levels in gestational hypertension than normal pregnancies, in concordance with the other impaired placentation diseases. Additionally, a better comparison of the PlGF values was obtained when separating early onset of preeclampsia <37 weeks and late-onset of preeclampsia 37≥ weeks of gestations.

Serum Inhibin-A and PAPP-A2 in the prediction of pre-eclampsia during the first and second trimesters in high-risk women. Pregnancy Hypertens 2021; 25:116-122. [PMID: 34116346 DOI: 10.1016/j.preghy.2021.05.024] [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: 09/16/2020] [Revised: 05/28/2021] [Accepted: 05/30/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Maternal serum inhibin-A, pregnancy associated plasma protein-A (PAPP-A) and PAPP-A2 together with placental growth factor (PlGF), maternal risk factors and uterine artery pulsatility index (UtA PI) were analysed to study their ability to predict pre-eclampsia (PE). STUDY DESIGN Serial serum samples for the nested case-control study were collected prospectively at 12-14, 18-20 and 26-28 weeks of gestation from 11 women who later developed early-onset PE (EO PE, diagnosis < 34 + 0 weeks of gestation), 34 women who developed late-onset PE (LO PE, diagnosis ≥ 34 + 0 weeks) and 89 controls. MAIN OUTCOME MEASURES Gestational age -adjusted multiples of the median (MoM) values were calculated for biomarker concentrations. Multivariate regression analyses were performed to combine first trimester biomarkers, previously reported results on PlGF, maternal risk factors and UtA PI. Area under curve (AUC) values and 95% confidence intervals (CIs) for the prediction of PE and its subtypes were calculated. RESULTS A high first trimester inhibin-A predicted PE (AUC 0.618, 95%CI, 0.513-0.724), whereas PAPP-A and PlGF predicted only EO PE (0.701, 0.562-0.840 and 0.798, 0.686-0.909, respectively). At 26-28 weeks PAPP-A2 and inhibin-A predicted all PE subtypes. In the multivariate setting inhibin-A combined with maternal pre-pregnancy body mass index, prior PE and mean UtA PI predicted PE (0.811,0.726-0.896) and LO PE (0.824, 0.733-0.914). CONCLUSIONS At first trimester inhibin-A show potential ability to predict not only EO PE but also LO PE whereas PlGF and PAPP-A predict only EO PE. At late second trimester inhibin-A and PAPP-A2 might be useful for short-term prediction of PE.

Abstract
Background Preeclampsia (PE) is a complex pregnancy-related disease that endangers the safety of maternal and fetal. The purpose of this study is to reveal the pathogenesis of preeclampsia and discover new predictors from the perspective of peptidomics. The umbilical cord blood of PE and control group was analyzed by peptidomics. A peptide named Regulation of Proliferation Process in Preeclampsia (ROPPIP) was screened out to explore its role in the proliferation, migration and apoptosis of trophoblast cells in preeclampsia. Methods We compared and analyzed the umbilical cord blood of patients with PE and normal pregnant women using liquid chromatography-tandem mass spectrometry (LC-MS). hTR-8/Svneo cells cultured in vitro were divided into ROPPIP group and a disordered peptide group as control. Cell Counting Kit-8 (CCK-8) assay, flow cytometry, Transwell chamber assays and western blot analysis were performed to detect cell proliferation, invasion, migration and apoptosis, in addition to the expression of Matrix metalloproteinase-2 (MMP2), nuclear associated antigen Ki67, B-cell lymphoma-2 (Bcl2), Caspase 3, and β-actin protein. Results We identified 133 differential peptides. Of these, 51 were up-regulated while 82 were down-regulated. the polypeptide SFGVRMATASPTDGNV with low differential expression in the serum of PE patients was selected for the study, we named the polypeptide as Regulation of Proliferation Process in PE (ROPPIP). The experiment shows that ROPPIP can up-regulate the expression levels of MMP2, Ki67, and Bcl2 in HTR-8/Svneo cells, down-regulate the expression of caspase-3, promote the proliferation and migration of HTR-8/Svneo cells and inhibit the apoptosis induced by cisplatin, the activation of the phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway may be associated with the function of ROPPIP. Conclusions ROPPIP promotes HTR-8/Svneo cells migration and proliferation, and inhibits apoptosis, by regulating the activation of the PI3K/AKT/mTOR signaling pathway.

Abstract
OBJECTIVE We performed a retrospective study to assess the clinical utility of a new index, D-dimer/platelet count (DD/PLT) ratio, in discriminating preeclampsia from normal pregnancy and gestational hypertension during third trimester, compared to the biomarkers currently used, such as D-dimer (DD), platelet (PLT), lymphocyte (LIN) and neutrophil (NEU) counts, fibrinogen (FIB), PLT/NEU, NEU/LIN and PLT/LIN ratios. STUDY DESIGN We retrospectively included 213 subjects. Of them, 163 and 50 were singleton pregnant and healthy non-pregnant women, respectively. Among pregnant women, 105 had normal pregnancy, 33 had gestational hypertension, and 25 had preeclampsia. RESULTS Using Receiver Operating Curve (ROC) analysis, DD/PLT ratio showed significant higher area under the curve (AUC) (0.90; 95% confidence interval (CI) 0.84-0.95) in discriminating preeclampsia from normal pregnancy compared to those of DD, NEU, FIB, LIN, PLT/NEU, NEU/LIN and PLT/LIN ratios (p < .03). In discriminating preeclampsia from gestational hypertension, the DD/PLT AUC (0.90; 95% CI 0.79-0.96) was significantly higher than those of DD, NEU, FIB, LIN, NEU/LIN and PLT/LIN ratios (p < .03), and not statistically different from those of PLT (p = .22) and PLT/NEU ratio (p = .46). CONCLUSIONS This study shows that DD/PLT ratio helps to discriminate preeclampsia from normal pregnancy and gestational hypertension. Large-scale studies are needed to verify its clinical usefulness, and to suggest more appropriate cutoff values for a widespread use.

Abstract
Preeclampsia (PE) is a multifactorial pregnancy disease, characterized by new-onset gestational hypertension with (or without) proteinuria or end-organ failure, exclusively observed in humans. It is a leading cause of maternal morbidity affecting 3–7% of pregnant women worldwide. PE pathophysiology could result from abnormal placentation due to a defective trophoblastic invasion and an impaired remodeling of uterine spiral arteries, leading to a poor adaptation of utero-placental circulation. This would be associated with hypoxia/reoxygenation phenomena, oxygen gradient fluctuations, altered antioxidant capacity, oxidative stress, and reduced nitric oxide (NO) bioavailability. This results in part from the reaction of NO with the radical anion superoxide (O2•−), which produces peroxynitrite ONOO-, a powerful pro-oxidant and inflammatory agent. Another mechanism is the progressive inhibition of the placental endothelial nitric oxide synthase (eNOS) by oxidative stress, which results in eNOS uncoupling via several events such as a depletion of the eNOS substrate L-arginine due to increased arginase activity, an oxidation of the eNOS cofactor tetrahydrobiopterin (BH4), or eNOS post-translational modifications (for instance by S-glutathionylation). The uncoupling of eNOS triggers a switch of its activity from a NO-producing enzyme to a NADPH oxidase-like system generating O2•−, thereby potentiating ROS production and oxidative stress. Moreover, in PE placentas, eNOS could be post-translationally modified by lipid peroxidation-derived aldehydes such as 4-oxononenal (ONE) a highly bioreactive agent, able to inhibit eNOS activity and NO production. This review summarizes the dysfunction of placental eNOS evoked by oxidative stress and lipid peroxidation products, and the potential consequences on PE pathogenesis. Physiological ROS production is enhanced during pregnancy. eNOS is one of the main target of oxidative stress in PE placenta. eNOS is S-glutathionylated in PE placentas. eNOS is modified by lipid oxidation products in PE placentas.

Abstract
OBJECTIVE To investigate the effects of ALKBH5 on migration, invasion and epithelial-mesenchymal transition (EMT) of human trophoblast cells. METHODS The expression plasmid of ALKBH5 or a negative control plasmid (ALKBH5-NC) was transfected in human trophoblast HTR-8 /SVneo cells, and the expressions of ALKBH5 mRNA and protein were detected by qRT-PCR and Western blotting. Transwell assay was used to assess the changes in migration and invasion abilities of the trophoblast cells after the transfection. Western blotting was performed to detect the expressions of EMT-related proteins in the cells including vimentin, fibronectin, E-cadherin, N-cadherin, MMP9 and MMP2. RESULTS ALKBH5 mRNA and protein expressions were significantly higher in ALKBH5 group than in the control group (P < 0.05). Over-expression of ALKBH5 significantly attenuated migration and invasion abilities of HTR-8/Svneo cells (P < 0.05). Compared with the control cells, the cells overexpressing ALKBH5 showed an up-regulated expression of E-cadherin and down-regulated expressions of vimentin, fibronectin, N-cadherin, MMP9 and MMP2 (P < 0.05). CONCLUSIONS ALKBH5 is involved in the pathogenesis of preeclampsia by inhibiting EMT of trophoblast cells and hence reducing their migration and invasion abilities.

Abstract
OBJECTIVE To determine the predictive value for preeclampsia by using serum placental protein 13 (PP13) levels and uterine artery pulsatility index (PI) in the first trimester. METHODS This is a prospective observational study that was conducted in pregnant women with gestational age 11-13+6 weeks. Transabdominal uterine artery Doppler and serum PP13 level were performed at the first trimester aneuploidy screening visit. The predictive values of these tests were calculated. RESULTS Data from 353 pregnant women were analyzed. Twenty-nine cases developed preeclampsia. The sensitivity, specificity, positive predictive value and negative predictive value of serum PP13 levels in predicting preeclampsia were 51.7, 65.7, 11.9, and 93.8%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of the uterine artery PI in predicting preeclampsia were 10.3, 95.7, 17.7, and 92.3%, respectively. When a combination of serum PP13 levels and uterine artery PI were used to predict preeclampsia, the sensitivity, specificity, positive predictive value and negative predictive value were 58.6, 62.9, 12.4 and 94.4%, respectively. CONCLUSION This study demonstrated that the combination of serum PP13 level and uterine artery Doppler in the first trimester was increased the sensitivity for predicting preeclampsia.

Abstract
Sleep disordered breathing (SDB) is a common, yet under-recognized and undertreated condition in pregnancy. Sleep disordered breathing is associated with pregnancy complications including preeclampsia, gestational diabetes, preterm birth, as well as severe maternal morbidity and mortality. The identification of risk factors for SDB in pregnancy may improve screening, diagnosis, and treatment of SDB prior to the onset of pregnancy complications. The goal of this study was to determine whether fetal sex increases risk of SDB in pregnancy. A cohort of singleton (N = 991) pregnant women were recruited within 24 to 48 hours of delivery and answered questions regarding SDB symptoms by questionnaire. Women who reported frequent loud snoring at least 3 times a week were considered to have SDB. Hospital records were reviewed to extract information on fetal sex and pregnancy complications including preeclampsia, pregnancy-induced hypertension, gestational diabetes, preterm delivery, and low birth weight. Women carrying male fetuses were significantly more likely to have SDB (β = .37, P = .01, OR: 1.45 [95% CI: 1.09–1.94]). Fetal sex was associated with increased risk of hypertensive disorders of pregnancy (defined as preeclampsia and/or pregnancy-induced hypertension) among women with SDB in pregnancy (β = .41, P = .02, OR: 1.51[95%CI:1.08–2.11]).Fetal sex did not increase risk of preterm birth, low birth weight, or gestational diabetes among women with SDB in pregnancy. Women carrying male fetuses were approximately 1.5 times more likely to report SDB in pregnancy compared to women carrying female fetuses, and women with pregnancy-onset SDB carrying male fetuses were 1.5 times more likely to have hypertensive disorders of pregnancy compared to women with SDB carrying female fetuses. Confirmation of fetal sex as a risk factor may, with other risk factors, play a role in identifying women at highest risk of SDB complications in pregnancy.

Pecoraro V, Trenti T. Predictive value of serum uric acid levels for adverse maternal and perinatal outcomes in pregnant women with high blood pressure. A systematic review and meta-analysis. Eur J Obstet Gynecol Reprod Biol 2020; 252:447-454. [PMID: 32736271 DOI: 10.1016/j.ejogrb.2020.07.042] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 07/18/2020] [Accepted: 07/21/2020] [Indexed: 02/01/2023]
Abstract
OBJECTIVE High serum uric acid seems to be associated with pre-eclampsia. The expected utility of uric acid is related to the probability of occurrence of maternal and neonatal complications. We evaluated the accuracy of uric acid in predicting adverse maternal and perinatal outcomes in pregnant women with high blood pressure. METHODS We performed an electronic search for studies evaluating the accuracy of high serum uric acid levels in pregnant women with high blood pressure. The assessment of risk of bias was performed using the QUIPS tool. For each included study, we collected data about study characteristics and diagnostic test accuracy to construct 2 × 2 tables. Pooled sensitivity (Se), specificity (Sp) and diagnostic odds ratio (DOR) were estimated using a bivariate model. Grading the quality of the evidence was assessed using the GRADE approach. RESULTS Twenty-one studies, testing more than 6,000 women, met the inclusion criteria. The majority of studies were at low risk of bias. Ten studies evaluated the role of serum uric acid to predict pre-eclampsia, the pooled Se was 0.74 (95%CI 0.71-0.77), Sp was 0.66 (95%CI 0.63-0.68), and DOR was 9.67 (95%CI 4.57-20.47). The overall quality of evidence was evaluated as low. The GRADE rating was downgraduate for risk of bias and inconsistency. CONCLUSIONS No robust evidence currently exists to suggest that uric acid measurement is useful in predicting maternal and perinatal adverse outcomes.

Abstract
To date, the etiology of preeclampsia (PE) has not been clarified and the specific treatment is lacking; hence, early prediction and prevention are very important. Thus, a large number of biomarkers that may be associated with PE have been identified based on proteomics to provide a reference for the prediction of PE and for the understanding of the pathological mechanisms of this disease. This article briefly summarizes the application of proteomics in PE and the potential protein biomarkers to provide a reference for other researchers.

Abstract
Preeclampsia (PE) is a pregnancy-specific hypertensive syndrome recognized as the leading cause of maternal and fetal morbidity and mortality worldwide. Painful blood-collection procedures or low accuracy of non-invasive approaches require faster, patient-friendly, and more sensitive diagnostic technologies. Here we report a painless, highly sensitive detection platform using nanoporous microneedles (nMNs) that enables rapid capture of biomarkers present at sub-nanogram levels. The highly porous nanostructures on the nMN surface were prepared by anodization of aluminum MN and then functionalized by immobilization of capture antibodies to detect target biomarkers based on an immunoassay method. The immuno-functionalized nMN array demonstrated rapid capture of an estrogen (E2) biomarker for PE following a 1-min incubation and exhibited a concentration-dependent change in fluorescence intensity over the E2 range of 0.5 ng mL-1 to 1000 ng mL-1 after treatment with fluorescence-detection antibodies. Remarkably, the nMN patch selectively detected sub-nanogram-levels of E2 in subcutaneous interstitial fluid from rats with increased diagnostic accuracy as compared with commercial immunoassay kits. This bio-functionalized nMN platform showed improved biosensing capability for multiple PE-related biomarkers, including hormones and proteins. Furthermore, this painless method demonstrated efficacy as a point-of-need diagnostic platform using portable smartphone-based fluorescence microscope to obtain fluorescence images of biomarker-captured nMN arrays.

Abstract
PURPOSE OF REVIEW Pathophysiology of hypertensive disorders of pregnancy (HDP), especially preeclampsia, has not been fully elucidated. Most trials aimed at the prevention of preeclampsia have failed to show significant benefit and investigation of novel, modifiable risk factors is sorely needed. Sleep disordered breathing (SDB), a group of disorders for which treatments are available, meets these criteria. SDB impacts about a third of all pregnancies and is associated with hypertension in the general non-pregnant population. RECENT FINDINGS Recent studies have shown a high prevalence of SDB, especially in complicated pregnancies. Several studies have shown that pregnant women with SDB have a higher risk for developing HDP, and these two disorders are associated with similar maternal long-term cardiovascular outcomes. Based on limited animal models of gestational intermittent hypoxia and human studies, SDB and HDP share similar risk factors and some pathophysiological mechanisms. However, there is paucity of studies addressing causality of this association and identifying therapeutic targets for intervention. Maternal SDB represents a novel and modifiable risk factor of HDP. Further studies are needed in order to establish the exact mechanisms underlying this association and to identify specific areas for clinical interventions.

Abstract
The overexpressed soluble fms-like tyrosine kinase 1 (sFLT-1) in placenta is considered to be a potential therapeutic target for preeclampsia (PE). How to achieve efficient intervention of sFLT1 expression in the placenta is an urgent problem to be solved. PEG-PLA nanoparticle generated by double-emulsion methods is a novel siRNA delivery system. Synthetic placental CSA binding peptide (P-CSA-BP) is effective for targeting lipid-polymer nanoparticle to the placenta. We conjugated P-CSA-BP to the surface of PEG-PLA nanoparticle to create a novel placenta specific sFLT1 siRNA delivery system for the therapy of PE. Nanoparticles were synthesized using double emulsion method and characterized by dynamic light scattering and transmission electron microscopy (TEM). RT-PCR was employed to evaluate mRNA level and protein level was analyzed by ELISA kit. The tissue distribution of nanoparticles was observed through ex vivo images. The concentrations of nanoparticles in organs were measured using high-performance liquid chromatography. T-NPsisFLT1 had higher efficiency than NPsisFLT1 in accumulating in HTR-8/SVneo cells and significantly decreased the expression of sFLT1. Intravenously administered T-NPsisFLT1 specifically accumulated in placentas of mice. sFLT1 mRNA level in placenta and protein level in serum were declined by T-NPsisFLT1. T-NPsisFLT1 shown no obvious toxic effect on both mother and fetus. The utility of T-NPsisFLT1 nanoparticles as a sFLT1 siRNA placenta specific delivery system significantly silenced sFLT1 in mice and is safe for both mother and fetus. This nanoparticle is a novel potential therapeutic strategy for PE.

Abstract
Differential expression of microRNA (miR)-335-5p, a key tumor suppressor, has been detected in pre-eclampsia (PE) placentas. However, the role of miR-335-5p in the pathogenesis of PE and the factor modulating its aberrant expression remain unknown. The present study used JEG-3 cells in vitro to investigate these mechanisms. The role of miR-335-5p in proliferation, apoptosis and migration of JEG-3 cells was investigated using MTT, Annexin V-FITC/PI, Transwell migration and wound healing assays, respectively. miR-335-5p expression levels were analyzed using reverse transcription-quantitative PCR. The expression levels of E-cadherin, N-cadherin, Snail, specificity protein 1 (Sp1) and p53 were assessed using western blot analysis. Cell viability analysis was performed using the Cell Counting Kit-8 assay. The intracellular reactive oxygen species (ROS) levels were detected using a 2,7-dichlorodihydrofluorescein diacetate assay. The present results suggested that miR-335-5p did not affect the proliferation or apoptotic rate of JEG-3 cells. Overexpression of miR-335-5p significantly inhibited the migration of JEG-3 cells, decreased the expression levels of Sp1, N-cadherin and Snail, and increased E-cadherin expression. Sp1 silencing produced similar results in JEG-3 cells. H2O2 significantly increased the intracellular ROS levels and miR-335-5p expression, whereas N-acetyl-cysteine pretreatment prior to H2O2 treatment reversed the increases in miR-335-5p expression. Knockdown of p53 significantly decreased the expression levels of miR-335-5p in JEG-3 cells and in H2O2-treated cells. The present results suggested that miR-335-5p expression levels in trophoblast cells could be increased by ROS in a p53-dependent manner, leading to the downregulation of Sp1 and subsequent inhibition of epithelial to mesenchymal transition and cell migration. The present results may provide novel evidence on the etiology of PE.

Abstract
Background This study aimed to compare serum levels of vascular endothelial growth factor (VEGF) and the VEGF receptors, VEGFR-1 and VEGFR-2, free placental growth factor (fPGF), endostatin, and serum pregnancy-associated plasma protein-A (PAPP-A) levels in women with mild and severe preeclampsia and healthy pregnant women. Material/Methods A included patients diagnosed with mild preeclampsia (n=32), severe preeclampsia (n=32), and healthy pregnant women (n=24). Serum levels of VEGF-A, VEGFR-1, VEGFR-2, fPGF, endostatin, and PAPP-A levels were measured by enzyme-linked immunosorbent assay (ELISA). Results In women with mild and severe preeclampsia, the gestation age at birth and birth weight were found to be significantly lower than the control group (p<0.001). Serum levels of endostatin, VEGFR-1, and VEGF-A levels were significantly increased in pregnant women with preeclampsia compared with healthy pregnant women (p<0.001). Serum levels of PAPP-A, VEGFR-2, and fPGF were significantly higher in healthy pregnant women when compared with women with preeclampsia (p=0.024, p<0.001, and p<0.001, respectively), but there were no significant differences between women with mild and severe preeclampsia. Conclusions Reduced serum levels of the angiogenic factors PAPP-A, VEGFR-2, and fPGF distinguished between women with preeclampsia and normotensive pregnant women but did not significantly distinguish between mild and severe preeclampsia.

Abstract
The objective of this study is to determine the incidence, socio-demographic and clinical risk factors for preeclampsia and associated maternal and perinatal adverse outcomes. This is a nested case-control derived from the multicentre cohort study Preterm SAMBA, in five different centres in Brazil, with nulliparous healthy pregnant women. Clinical data were prospectively collected, and risk factors were assessed comparatively between PE cases and controls using risk ratio (RR) (95% CI) plus multivariate analysis. Complete data were available for 1,165 participants. The incidence of preeclampsia was 7.5%. Body mass index determined at the first medical visit and diastolic blood pressure over 75 mmHg at 20 weeks of gestation were independently associated with the occurrence of preeclampsia. Women with preeclampsia sustained a higher incidence of adverse maternal outcomes, including C-section (3.5 fold), preterm birth below 34 weeks of gestation (3.9 fold) and hospital stay longer than 5 days (5.8 fold) than controls. They also had worse perinatal outcomes, including lower birthweight (a mean 379 g lower), small for gestational age babies (RR 2.45 [1.52-3.95]), 5-minute Apgar score less than 7 (RR 2.11 [1.03-4.29]), NICU admission (RR 3.34 [1.61-6.9]) and Neonatal Near Miss (3.65 [1.78-7.49]). Weight gain rate per week, obesity and diastolic blood pressure equal to or higher than 75 mmHg at 20 weeks of gestation were shown to be associated with preeclampsia. Preeclampsia also led to a higher number of C-sections and prolonged hospital admission, in addition to worse neonatal outcomes.

Abstract
Preeclampsia impairs fetoplacental vascular function and increases risks of adult-onset cardiovascular disorders in children born to preeclamptic mothers, implicating that preeclampsia programs fetal vasculature in utero. However, the underlying mechanisms remain elusive. We hypothesize that preeclampsia alters fetal endothelial gene expression and disturbs cytokines- and growth factors-induced endothelial responses. RNA sequencing analysis was performed on unpassaged human umbilical vein endothelial cells (HUVECs) from normotensive and preeclamptic pregnancies. Functional assays for endothelial monolayer integrity, proliferation, and migration were conducted on passage 1 HUVECs from normotensive and preeclamptic pregnancies. Compared with normotensive cells, 926 and 172 genes were dysregulated in unpassaged female and male HUVECs from preeclamptic pregnancies, respectively. Many of these preeclampsia-dysregulated genes are associated with cardiovascular diseases (eg, heart failure) and endothelial function (eg, cell migration, calcium signaling, and endothelial nitric oxide synthase signaling). TNF (tumor necrosis factor)-α-, TGF (transforming growth factor)-β1-, FGF (fibroblast growth factor)-2-, and VEGFA (vascular endothelial growth factor A)-regulated gene networks were differentially disrupted in unpassaged female and male HUVECs from preeclamptic pregnancies. Moreover, preeclampsia decreased endothelial monolayer integrity in responses to TNF-α in both female and male HUVECs. Preeclampsia decreased TGF-β1-strengthened monolayer integrity in female HUVECs, whereas it enhanced FGF-2-strengthened monolayer integrity in male HUVECs. Preeclampsia promoted TNF-α-, TGF-β1-, and VEGFA-induced cell proliferation in female, but not in male HUVECs. Preeclampsia inhibited TNF-α-induced cell migration in female HUVECs, but had an opposite effect on male HUVECs. In conclusion, preeclampsia differentially dysregulates cardiovascular diseases- and endothelial function-associated genes/pathways in female and male fetal endothelial cells in association with the sexual dimorphisms of preeclampsia-dysregulated fetal endothelial function.

Abstract
BACKGROUNDS AND OBJECTIVES Preeclampsia (PE) is one of the leading causes of maternal and neonatal morbidity and mortality. Preeclampsia is associated with aberrant expression of several MicroRNAs which function as gene regulators. The present study aims to determine the expression of MicroRNA-210 and MicroRNA-155 in Preeclampsia, and to detect the association of MicroRNA-210 and MicroRNA-155 levels with the severity of Preeclampsia. METHODS The study was carried out on thirty PE pregnant women as the Preeclampsia group compared to twenty healthy pregnant women who served as the control group. The patients were chosen at labor wards from Ain Shams Maternity Hospital during the period from June to December 2016. Preeclampsia group was then subdivided into mild Preeclampsia and severe Preeclampsia subgroups according to the levels of arterial blood pressure with the presence of thrombocytopenia, impairment in liver function, progressive renal insufficiency, pulmonary edema and cerebral or visual disturbance. MicroRNA-210 and MicroRNA-155 were estimated by a quantitative real time polymerase chain reaction (qRT-PCR). Results of this study showed that the levels of MicroRNA-210 and MicroRNA-155 detected in the Preeclampsia group are significantly higher than in the control group. Although MicroRNA-210 levels showed high significant increase in severe PE compared to mild PE cases, there were no significant differences in MicroRNA-155 levels between the two PE subgroups detected. CONCLUSIONS MicroRNA-210 may be the noncoding RNA at the molecular level in which the increase in its level accompanies the progression of PE; and is closely associated with the severity of Preeclampsia.

Biochemical Markers for Prediction of Hypertensive Disorders of Pregnancy. J Med Biochem 2019; 38:71-82. [PMID: 30820186 PMCID: PMC6298456 DOI: 10.2478/jomb-2018-0001] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Accepted: 01/27/2018] [Indexed: 12/01/2022] Open
Abstract
Background Gestational hypertension (GH) and pre eclampsia (PE) are the most common gestational complications. Several placental biochemical markers are used to predict GH/PE, but with conflicting results. Methods The study aim was to estimate the biochemical markers’ ability to predict hypertensive disorders in pregnancy. On the first ultrasonographic examination, 104 healthy pregnant women were recruited. At the regular pregnancy check-ups, BMI, blood pressure, occurrence of gestational hypertension (early or late onset), preeclampsia, eclampsia and other complications were recorded. Serum concentrations (in multiples of median – MoM) of human chorionic gonadotropin (HCG) and pregnancyassociated plasma protein A (PAPPA) were measured from the 11th to 14th gestational week, while HCG, alpha feto protein (AFP), estriol and inhibin were determined between the 16th and 19th gestational week. Results Hypertensive disorders throughout pregnancy were diagnosed in 20.2% women. Early-onset GH was registered in 7 and PE in 6 patients, while 14 had late-onset GH and 10 additional women PE. There were no significant differences (p≥0.05) in biochemical markers concentrations between women with and without GH/PE. PAPPA levels in the first and HCG in the second trimester correlated with early and late GH/PE. Moreover, higher AFP concentrations were registered in women with preeclampsia signs/symptoms. According to ROC analysis, AFP>1.05 MoM properly identified 80% of GH/PE cases. Obtained models imply that HCG, PAPPA and AFP should be used for GH/PE prediction. Conclusions Biochemical markers HCG, PAPPA and AFP could be useful in predicting gestational hypertension and preeclampsia. However, different markers should be used for early and late onset GH/PE.

Abstract
INTRODUCTION Soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) is linked to endothelial dysfunction; a key factor in pre-eclamptic pathogenesis. This study aimed to compare sTWEAK levels during pregnancy to assess for its prognostic ability. MATERIALS AND METHODS Sixty three high risk pregnant women were followed up from 12 weeks of gestation till term. Serum levels of sTWEAK and platelet derived growth factor (PlGF), blood pressure, serum glucose, uric acid, urea/creatinine and liver function tests were measured. Subjects were stratified according to the ACOG criteria as women who developed PE, or PIH or remained normotensive at term. A negative control group of normotensive healthy pregnant women (n = 17) was also recruited for comparison. RESULTS Baseline sTWEAK levels were lower (4.03 ± 0.37 ng/dl) in HR cohort that developed PE and further reduced at term (1.93 ± 0.23 ng/dl) as compared to HR subjects who remained normotensive and negative control group (30.53 ± 0.79 ng/dl; p < 0.01). Likewise PlGF levels were significantly lower (74.22 ± 10.11 pg/ml) in HR cohort that developed PE (p = 0.013). At term 39.68% (n = 22) HR subjects with low sTWEAK developed PIH and 34.92% (n = 24) developed PE. In terms of high risk characteristics observed in the HR group; 73% of the subjects were multiparous, whereas 26.98% reported to have developed PE in previous pregnancies. CONCLUSION sTWEAK levels at early pregnancy weeks were found to be low in high risk females who developed PE at follow up versus normotensive pregnant women. Baseline TWEAK might serve as an independent variable for prediction of pre-eclampsia; however longitudinal studies with larger sample size are required to ascertain the causal relation.

Abstract
In recent years, the study of metabolomics has begun to receive increasing international attention, especially as it pertains to medical research. This is due in part to the potential for discovery of new biomarkers in the metabolome and to a new understanding of the "exposome", which refers to the endogenous and exogenous compounds that reflect external exposures. Consequently, metabolomics research into pregnancy-related issues has increased. Biomarkers discovered through metabolomics may shed some light on the etiology of certain pregnancy-related complications and their adverse effects on future maternal health and infant development and improve current clinical management. The discoveries and methods used in these studies will be compiled and summarized within the following paper. A further focus of this paper is the use of hair as a biological sample, which is gaining increasing attention across diverse fields due to its noninvasive sampling method and the metabolome stability. Its significance in exposome studies will be considered in this review, as well as the potential to associate exposures with adverse pregnancy outcomes. Currently, hair has been used in only two metabolomics studies relating to fetal growth restriction (FGR) and gestational diabetes mellitus (GDM).

The silencing of ApoC3 suppresses oxidative stress and inflammatory responses in placenta cells from mice with preeclampsia via inhibition of the NF-κB signaling pathway. Biomed Pharmacother 2018; 107:1377-1384. [PMID: 30257353 DOI: 10.1016/j.biopha.2018.08.122] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 08/22/2018] [Accepted: 08/23/2018] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE Preeclampsia is one of the three primary causes of maternal morbidity and mortality worldwide. This study evaluated ApoC3 in placenta cells of mice with preeclampsia to explore its therapeutic role in preeclampsia and assess its function on oxidative stress and inflammatory responses involving the NF-κB signaling pathway. METHODS A mouse model of preeclampsia was successfully established. APOC3-siRNA with the best silencing effect was screened out. The expression levels of ApoC3, p65, and IkBα were evaluated. The effect of ApoC3 silencing on metabolic activity and apoptosis was measured. The level of high-sensitivity C-reactive protein (hs-CPR), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α), the activity of matrix metalloproteinase (MMP)-2 and MMP-9, and the expression of malondialdehyde (MDA), 8-isoprostane and oxidized low-density lipoprotein (ox-LDL) were determined. RESULTS ApoC3-siRNA-3 was the most effective siRNA. The mRNA expression of ApoC3 was scarcely observed, while the expression of p65 decreased and the expression of p-IkBα increased in the ApoC3-siRNA group. Compared with those in the model and empty vector groups, the cell apoptosis rate and the activities of invasion-related factors MMP-2 and MMP-9 increased, while the levels of hs-CPR, IL-6, TNF-α, MDA, 8-isoprostane, and ox-LDL decreased in the ApoC3-siRNA group. CONCLUSION Silencing ApoC3 could suppress the NF-κB signaling pathway, thereby exercising a protective effect on cell injury induced by oxidative stress and reducing inflammatory responses.

Abstract
Preeclampsia (PE) is a pregnancy disorder that increases maternal and fetal
morbidity and mortality worldwide. High plasma levels of homocysteine (Hcy) are
a risk factor for several cardiovascular diseases. Cystathionine β-synthase
(CBS) plays an important role in Hcy homeostasis catalyzing the irreversible
degradation of Hcy to cystathionine, protecting the endothelium from injury
caused by hypoxia. Several mutations and polymorphisms may alter the expression
of the CBS gene, resulting in variable levels of Hcy. The
purpose of this study was to investigate the association of CBS
gene polymorphisms with PE in Mexican women. A case–control study consisting of
129 pregnant women with PE (37 severe and 92 mild) and 173 women with
uncomplicated pregnancies was performed. Polymorphisms, such as G797A, C785T,
T833C, G919A, T959C, C1105T, and 844ins68 base pair, in the CBS
gene were genotyped. The polymorphism G797A was monomorphic in cases with the
presence of only G797A-G allele. Allele C785T-T and genotype C785T-C/T were
associated with susceptibility in severe and mild PE. Alleles G797A-G and
T959C-T were associated with susceptibility only in severe PE. Haplotype TGTWGTC
was of susceptibility for severe PE and of protection for mild PE. Haplotypes
CGTWGCC and CATWGTC seem to be protective for severe PE, but the latter is
related to susceptibility in mild PE. The results suggest that C785T, G797A, and
T959C mutations are contributing in different ways in severe and mild PE in our
population and could be count as another related factor for this disease.

Abstract
Preeclampsia (PE) is a major cause of maternal and perinatal morbidity and mortality, particularly in developing countries. In Mongolia, preeclampsia and eclampsia have occurred among pregnancy complications at a rate of 25% in recent years. Recent studies in the literature have screened for preeclampsia by combining maternal factors with biomarkers. This study was conducted using prospective cohort research including 393 singleton pregnancies at 11–13+6 weeks. Maternal plasmas pregnancy-associated plasma protein-A (PAPP-A) and maternal serum placental growth factor (PlGF) were measured using Perkin Elmer time-resolved fluoroimmunoassay (DELFIA) kits, and the measurement of mean arterial pressure (MAP) was performed by automated devices and the uterine artery pulsatility index was measured by Doppler ultrasound. In the study population, there were 16.7% showing complicated preeclampsia. The receiver-operating characteristics (ROC) curve analysis showed a sensitivity of 71.21%, and a specificity of 75.54% when the mean arterial pressure cut-off was 89.5 mm; while a sensitivity of 33.36% and specificity of 77.68% were observed when the uterine artery mean pulsatility index (mPI) cut-off was 2.34; a sensitivity of 79.66% and specificity of 44.04% were observed when the PAPP-A cut-off was 529.1 mU/L; and a sensitivity of 74.58% and specificity of 46.6% were observed when the PlGF cut-off was 39.87 pg/mL. The detection rates following the combination of markers with the maternal history were as follows: 62.7% with mean arterial pressure, 69.5–82.9% with two markers 86.5% with three markers and 91.4% with four markers. In conclusion, the mean arterial pressure was highly sensitive and demonstrated its easy usage and cost-effectiveness as a predictive marker for the early screening of preeclampsia from other biomarkers.

Abstract
Placental protein 13 (PP13), a glycan binding protein predominantly expressed in syncytiotrophoblast, dimeric in nature, lacks N-terminal signal peptide, bypasses the endoplasmic reticulum, and secretes into maternal circulation as exosomes or microvesicles. PP13 has jelly roll fold conformation with conserved carbohydrate recognition domain which specifically binds to β-galactosides of the glycan receptors during placentation. PP13 binds to glycosylated receptors on human erythrocytes and brings about hemagglutination by the property of lectin activity; other functions are immunoregulation and vasodilation during placentation and vascularization. The gene LGALS13 located on 19q13.2 comprising four exons expresses a 32-kDa protein with 139 amino acid residues, PP13. Impaired expression due to mutation in the gene leads to a nonfunctional truncated PP13. The low serum levels predict high risk for the onset of preeclampsia or obstetric complications. Hence, PP13 turned to be an early marker for risk assessment of preeclampsia. The recombinant PP13 and monoclonal antibodies availability help for replenishing PP13 in conditions with low serum levels and for detection and prevention of preeclampsia, respectively.

Abstract
Insufficient trophoblast invasion is associated with preeclampsia (PE) development. Retinol-binding protein 4 (RBP4) is important for regulating cell differentiation, migration and invasion. The aim of the present study was to determine RBP4 expression and function in the human placenta and to examine the underlying mechanisms. In the present study, RBP4 expression was determined in serum samples from 35 pregnant women with PE and 30 healthy pregnant women using enzyme-linked immunosorbent assays. Cell proliferation was assessed by Cell Counting Kit-8 assays, and cell invasion was examined with transwell assays. RBP4 concentrations were significantly lower in the PE group when compared with the control group. RBP4 overexpression enhanced HTR8/SVneo cell proliferation and invasion, and the levels of phosphorylated (p-) phosphoinositide 3-kinase (PI3K) and p-protein kinase B (AKT) in HTR8/SVneo cells. RBP4 knockdown significantly inhibited HTR8/SVneo cell proliferation and invasion, and repressed the expression of matrix metalloproteinases. In addition, RBP4 knockdown significantly reduced the levels of p-PI3K and p-AKT in HTR8/SVneo cells. Taken together, the results of the present study demonstrated that RBP4 overexpression increased HTR8/SVneo cell proliferation and invasion by suppressing PI3K/AKT signaling and RBP4 knockdown induced the opposite effects.

Abstract
Preeclampsia (PE) is a disorder which affects 1-10% of pregnant women worldwide. It is characterised by hypertension and proteinuria in the later stages of gestation and can lead to maternal and perinatal morbidity and mortality. Other than the delivery of the foetus and the removal of the placenta, to date there are no therapeutic approaches to treat or prevent PE. It is thus only possible to reduce PE-related mortality through early detection, careful monitoring, and treatment of the symptoms. For these reasons the search for noninvasive, blood-borne, or urinary biochemical markers that could be used for the screening, presymptomatic diagnosis, and prediction of the development of PE is of great urgency. So far, a number of biomarkers have been proposed for predicting PE, based on pathophysiological observations, but these have mostly proven to be unreliable and inconsistent between different studies. The clinical presentation of PE and data gathered for the biochemical markers placental growth factor (PlGF), soluble Feline McDonough Sarcoma- (fms-) like tyrosine kinase-1 (sFlt-1), asymmetric dimethylarginine (ADMA), and methyl-lysine is being reviewed with the aim of providing both a clinical and biochemical understanding of how these biomarkers might assist in the diagnosis of PE or indicate its severity.

Abstract
Sickle cell disease (SCD) in pregnancy can be associated with adverse maternal and perinatal outcomes. Furthermore, complications of SCD can be aggravated by pregnancy. Optimal prenatal care aims to decrease the occurrence of maternal and fetal complications. A retrospective, French, two-center study compared two care strategies for pregnant women with SCD over two time periods. In the first study period (2005-2010), the women were systematically offered prophylactic transfusions. In the second study period (2011-2014), a targeted transfusion strategy was applied whenever possible, and home-based prophylactic nocturnal oxygen therapy was offered to all the pregnant women. The two periods did not differ significantly in terms of the incidence of vaso-occlusive events. Maternal mortality, perinatal mortality, and obstetric complication rates were also similar in the two periods, as was the incidence of post-transfusion complications (6.1% in 2005-2010 and 1.3% in 2011-2014, P = .15), although no de novo alloimmunizations or delayed hemolysis transfusion reactions were observed in the second period. The results of this preliminary, retrospective study indicate that targeted transfusion plus home-based prophylactic nocturnal oxygen therapy is safe and may decrease transfusion requirements and transfusion-associated complications.

Magnesium Supplementation and Blood Pressure in Pregnancy: A Double-Blind Randomized Multicenter Study. J Pregnancy 2018; 2018:4843159. [PMID: 30002931 PMCID: PMC5996415 DOI: 10.1155/2018/4843159] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Revised: 04/29/2018] [Accepted: 05/07/2018] [Indexed: 11/17/2022] Open
Abstract
Objective To investigate the effect of magnesium (Mg) supplementation in healthy pregnant women for prevention of blood pressure increase. Secondary outcomes were comparison of biomarkers for hypertensive disorders and labour and fetal outcomes between the groups. Methods Two hundred nulliparous healthy pregnant women were double-blind randomized to receive Mg daily or placebo. Results There were no differences in blood pressure increase. However, among the Mg-treated women, there was a significant negative correlation between increase in blood levels of magnesium and increase in systolic blood pressure (p = 0.042). Magnesium supplementation seems to be safe for both mother and infant. Conclusion Magnesium supplementation in healthy first-time pregnant women is not to be recommended for prevention of blood pressure increase. Supplementation in risk pregnancies needs to be further investigated. The study is listed on the ISRCTN registry with study ID 13890849.

Abstract
Preeclampsia affects up to 8% of pregnancies worldwide and is a leading cause of both maternal and fetal morbidity and mortality. Our current understanding of the cause(s) of preeclampsia is far from complete, and the lack of a single reliable animal model that recapitulates all aspects of the disease further confounds our understanding. This is partially due to the heterogeneous nature of the disease, coupled with our evolving understanding of its etiology. Nevertheless, animal models are still highly relevant and useful tools that help us better understand the pathophysiology of specific aspects of preeclampsia. This review summarizes the various types and characteristics of animal models used to study preeclampsia, highlighting particular features of these models relevant to clinical translation. This review points out the strengths and limitations of these models to illustrate the importance of using the appropriate model depending on the research question.

Abstract
INTRODUCTION Air pollution is a hot topic and is known to cause multiple health issues. Especially pregnant women seem to be vulnerable to environmental issues. There are data suggesting that exposure contributes to hypertensive disorders.This study aims to evaluate the effects of exposure to particulate matter (PM) and outdoor air pollutants on the clinical pregnancy outcome for mother and child and to determine which biochemical changes in maternal, placental and cord blood best explain this effect. METHODS AND ANALYSIS This study is a prospective cohort study. We aim to recruit 200 pregnant women. The outcome measurements will include maternal parameters, labour parameters and neonatal parameters.Multiple samples will be analysed such as maternal urine samples (8-oxo-deoxyguanosine), maternal blood samples (routine blood sampling, biomarkers of pre-eclampsia and transcript markers), maternal hair samples, neonatal blood samples (transcript markers) combined with extensive questionnaires. ETHICS AND DISSEMINATION We obtain informed consent from each participant prior to enrolment in the study.The study has received approval by the Ethical Committee of the Antwerp University Hospital (14/40/411).IPANEMA is the first prospective study to assess the impact of PM on mothers and babies in Antwerp, Belgium.Findings from this study will contribute to improve knowledge on the impact of exposure to air pollution on mothers and babies and will also define biomarkers as predictors for pregnant women at risk. TRIAL REGISTRATION ClinicalTrials.gov: 14/40/411. Registered 22-10-2015.
