Abstract
Early-onset preeclampsia (EOPE) is a complex pregnancy complication that poses significant risks to the health of both mothers and fetuses, and research on its pathogenesis and pathophysiology remains insuffcient. This study aims to explore the role of candidate genes and their potential interaction mechanisms in EOPE through bioinformatics analysis techniques. Two gene expression datasets, GSE44711 and GSE74341, were obtained from the Gene Expression Omnibus (GEO) to identify differentially expressed genes (DEGs) between EOPE and gestational age-matched preterm control samples. Functional enrichment analysis was performed utilizing the kyoto encyclopedia of genes and genomes (KEGG), gene ontology (GO), and gene set enrichment analysis (GSEA). A protein-protein interaction (PPI) network was constructed using the STRING database, and hub DEGs were identified through Cytoscape software and comparative toxicogenomics database (CTD) analysis. Furthermore, a diagnostic logistic model was established using these hub genes, which were confirmed through reverse transcription polymerase chain reaction (RT-PCR). Finally, immune cell infiltration was analyzed using CIBERSORT. In total, 807 DEGs were identified in the GSE44711 dataset (451 upregulated genes and 356 downregulated genes), and 787 DEGs were identified in the GSE74341 dataset (446 upregulated genes and 341 downregulated genes). These DEGs were significantly enriched in various molecular functions such as extracellular matrix structural constituent, receptor-ligand activity binding, cytokine activity, and platelet-derived growth factor. KEGG and GSEA annotation revealed significant enrichment in pathways related to ECM-receptor interaction, PI3K-AKT signaling, and focal adhesion. Ten hub genes were identified through the CytoHubba plugin in Cytoscape. Among these hub genes, three key DEGs (COL1A1, SPP1, and THY1) were selected using CTD analysis and various topological methods in Cytoscape. The diagnostic logistic model based on these three genes exhibited high efficiency in predicting EOPE (AUC = 0.922). RT-PCR analysis confirmed the downregulation of these genes in EOPE, and immune cell infiltration analysis suggested the significant role of M1 and M2 macrophages in EOPE. In conclusion, this study highlights the association of three key genes (COL1A1, SPP1, and THY1) with EOPE and their contribution to high diagnostic efficiency in the logistic model. Additionally, it provides new insights for future research on EOPE and emphasizes the diagnostic value of these identified genes. More research is needed to explore their functional and diagnostic significance in EOPE.

Abstract
MicroRNA is associated with angiogenesis, invasion, proliferation, and vascular endothelial remodeling of various diseases. We aimed to investigate serum MicroRNA (miRNA) levels in preeclampsia (PE) and to determine whether any changes in miRNA levels are useful in predicting early onset preeclampsia (EOPE) and adverse perinatal outcomes. A total of 89 pregnant patients were enrolled in this prospective case-control study (55 PE and 34 healthy controls). miR-17, miR-20a, miR-20b, miR126, miR155, miR-200, miR-222, and miR-210 levels were studied in maternal serum in preeclamptic pregnant women. Multiple logistic regression analyses analyzed the risk factors which are associated with EOPE and adverse maternal outcomes. The Real-time RT-PCR method was used to determine maternal serum miRNA levels. Serum miR-17, miR-20a, miR-20b, miR126, and miR-210 levels were significantly higher in PE than the control group (p < .001, p < .001, p < .001, p < .001 and p = .047 respectively). Increased miR-17, miR-20a, and miR-20b levels were independently associated with PE (OR: 0.642, 95%Cl: 0.486-0.846, p = .002; OR: 0.899, 95%Cl: 0.811-0.996, p = .042 and OR: 0.817, 95%Cl: 0.689-0.970, p = .021). Increased miR-17 and miR-126 levels were negatively correlated with serum EOPE in PE (r = -.313, p = .020), and increased miR-210 levels were significantly positively correlated with EOPE in PE (r = .285, p = .005). Increased expression of serum miR-17, miR-20a, miR-20b, miR126, and miR-210 were found to be associated with PE, also increased expression of miR-17, miR-20a, and miR-20b were to be predicted with PE, also increased maternal serum miR-17 and miR-126 expressions were negatively correlated and increased miR-210 expression was positively correlated with EOPE in PE women.

Abstract
OBJECTIVE To find out the predictive value of sFlt-1/PlGF ratio for antenatal risk stratification (ARS) of women at high risk of preeclampsia (PE). METHODS Antenatal women at high risk of PE underwent sFlt-1/PlGF ratio at 20-22, 28-30 and 34-36 weeks and were followed till delivery. Those who developed PE were cases those who had normal outcome were controls, the cases and controls were compared. RESULTS Hypertension in pregnancy was seen in 116/287 (40.4 %), 46/287(16.0 %) had PE and 21(7.3 %) had early onset PE. Mean arterial pressure at 20-22 weeks was the high in those who developed early onset PE (109.08 ± 9.74 mmHg). The sFlt-1/PlGF ratio of 38 or more at 20-22 weeks resulted in either PE or adverse fetal outcome in all cases. Whereas, the ratio of less than 38 ruled out PE in all cases up to 29 + 6 weeks. At 28-30 weeks, the ratio less than 38 predicted no PE up to 34 weeks and no complication up to 29+6 weeks. The sensitivity for the detection at later gestation further decreased as the gestation advanced however the specificity was above 98 % at all gestations. The positive predictive value of the test increased with the advancing gestation, the negative predictive value was 93 % or higher at all gestations. CONCLUSION The usefulness of sFlt-1/PlGF ratio ≥38 for risk stratification was validated in the study, the testing at 28-30 weeks appeared to be the best time to test for PE prediction in high risk women.

Abstract
INTRODUCTION The importance of eosinophils in the pathogenesis of preeclampsia is an question of interest and there are recent studies in the literature indicating significantly lower eosinophil count values in pregnant women with preeclampsia. The present study aims to evaluate the utility of first-trimester eosinophil count and eosinophil-based complete blood cell count indices in the prediction of preeclampsia. METHODS Pregnant women diagnosed with preeclampsia (n = 281) were retrospectively compared with a control group (n = 307). The utility of first trimester eosinophil count, neutrophil to eosinophil ratio (NER) (neutrophil/eosinophil), leukocyte to eosinophil ratio (LER) (leukocyte/eosinophil), eosinophil to monocyte ratio (EMR) (eosinophil/monocyte) and, eosinophil to lymphocyte ratio (ELR) (eosinophil/lymphocyte) in the prediction of preeclampsia were evaluated. RESULTS Optimal cut-off values for eosinophil count, NER, LER, EMR and, ELR in predicting preeclampsia were 0.07 (AUC: 0.62, 58.7% sensitivity, 56.4% specificity), 90.9 (AUC: 0.65, 61.1% sensitivity, 59.4% specificity), 125.7 (AUC: 0.64, 61.4% sensitivity, 58.4% specificity), 0.15 (AUC: 0.63, 60.1% sensitivity, 59.6% specificity) and, 0.03 (AUC: 0.62, 60.9% sensitivity, 57% specificity), respectively. Mentioned values in predicting early-onset preeclampsia were 0.07 (AUC: 0.64, 60.5% sensitivity, 50.8% specificity), 102.1 (AUC: 0.64, 62.4% sensitivity, 58.8% specificity), 140.2 (AUC: 0.65, 63.5% sensitivity, 59.1% soecificity), 0.14 (AUC: 0.66, 66.3% sensitivity, 59.2% specificity), and, 0.03 (AUC: 0.63, 60.5% sensitivity, 57.4% specificity), respectively. The optimal cut-off value for EMR in the prediction of preeclampsia with severe features was 0.16 (AUC: 0.56, 56.9% sensitivity, 53.2% specificity). DISCUSSION Eosinophil-based complete blood count indices may be used to predict early-onset preeclampsia with relatively low sensitivity and specificity.

Abstract
BACKGROUND Preeclampsia (PE) is a multisystemic metabolic disease with an undetermined etiology. PE is a worldwide cause of maternal and perinatal morbidity, subdivided into early (EoPE) and late-onset (LoPE) according to 34 wk of gestation as a divider. Many researchers investigated biomarkers for predicting PE to halt its consequences on the feto-maternal outcome. Elabela (Ela) is a newly discovered peptide hormone that was implicated in PE pathogenesis. Earlier rodent studies discussed Ela’s role in controlling blood pressure. Moreover, Ela deficiency was associated with PE development.
AIM To test whether plasma Ela could serve as a reliable marker for predicting PE based on the time of onset (EoPE vs LoPE) compared to age and body mass matched healthy controls since no definitive treatment exists for PE but to terminate a pregnancy.
METHODS This case-control study recruited (n = 90) pregnant who fulfilled inclusion criteria; they were allocated into three groups: EoPE (30/90) (< 34 wk of gestation); LoPE (30/90) (≥ 34 wk of gestation); and healthy pregnant (30/90). Demographic criteria; biochemical, hematological, and maternal plasma Ela levels were recorded for comparison.
RESULTS Serum Ela was significantly reduced in EoPE compared to LoPE and healthy controls (P = 0.0023). The correlation confirmed a strong inverse relationship with mean atrial blood pressure (r = -0.7, P < 0.001), while gestational age and platelets count showed a moderate correlation with (r = 0.4 with P < 0.0001). No correlation was confirmed between the body mass index (BMI) and urine albumin. The predictive ability of 25 centile serum Ela had an Odds ratio of 5.21, 95% confidence interval (1.28, 21.24), P = 0.02 for predicting EoPE. The receiver operator characteristic curve defined the Ela cutoff value at > 9.156 with 96.7% and 93.3% sensitivity and specificity, P < 0.0001 in predicting EoPE.
CONCLUSION A strong correlation of serum Ela with PE parameters with excellent sensitivity and specificity in distinguishing EoPE independent of the BMI, age, and blood pressure which makes Ela a recommendable marker in screening. Further research is warranted to explore prognostic and therapeutic applications for Ela in PE.

Abstract
BACKGROUND Recent advancement on experiment concluded that etiology of pre-eclampsia (PE) could be explained by the "two-stage" theory. The theory of which explained that pre-eclampsia occurs due to abnormalities in spiral arteries development and release of inflammatory response. Failure of spiral arteries development, the lesion of damage could be due to ischemia-reperfusion or hypoxia-reoxygenation. Hypoxia in pre-eclamptic placenta leads to metabolic change to anaerobic in glycolysis. Lactate dehydrogenase (LDH) has important role in anaerobic glycolysis that catalyzes the conversion of lactate to pyruvate during hypoxia. On the other hand, phosphoenolpyruvate carboxy kinase (PEPCK) is merely an enzyme of gluconeogenesis. This research conduct to reveal that in early onset pre-eclampsia the placenta still hypoxic and undergoes gluconeogenesis even after delivery, through metabolic enzyme of LDH and PEPCK level. METHODS This cross-sectional study compared early onset PE (< 34 weeks) with normal term placenta. We measured LDH enzyme activity using colorimetric assay and PEPCK protein using ELISA method. RESULTS Result show that placental LDH specific activity was increased significantly in PE with median 2.750 (0.030 - 5.680) U/mg compared to normal term placenta 0.255 (0.032 - 1.194) U/mg (Mann-Whitney, p< 0.001). PEPCK level was significantly increased in PE 8.998 (1.737-44.914) ng/mg compared to normal term placenta 1.552 (0.741-8.832) ng/mg (Mann-Whitney, p< 0.001). CONCLUSION We conclude that anaerobic glycolysis and gluconeogenesis pathway are increased in early onset PE placenta as adaptation mechanism to hypoxic condition.

Abstract
Background The data on the association between the microbiota-dependent metabolite trimethylamine-N-oxide (TMAO) during pregnancy and risk of preeclampsia (PE) is limited. Methods We, therefore, conducted a prospective nested case control study during Sep 2017 to Dec 2018 to examine the association between plasma TMAO measured during pregnancy and the risk of PE. Total of 17 patients diagnosed with early onset PE (EOPE), 49 with late onset PE (LOPE) and 198 healthy controls were enrolled. Blood samples were collected at 15–23 weeks gestation and time at delivery. The Logistic regression model was used to assess the odds ratio (OR) and 95% confidence interval (CI) for TMAO and risk of PE, EOPE, LOPE, mild PE, and severe PE. Results We found that the mean TMAO levels of overall subjects in the second trimester (T2) and at the time of delivery (TD) were 90.39 μg/m3 (standard deviation (SD) =45.91) and 175.01 μg/m3 (SD = 160.97), respectively. No significant spearman correlation was found between the TMAO in those two periods (p > 0.05). T2 TMAO was not significantly associated with risk of PE or risk of any PE subtypes (p > 0.05). However, TD TMAO was significant associated with risk of PE, EOPE and severe PE (adjusted OR and 95%CI were 1.24(1.09, 1.40), 1.62(1.29, 2.03), and 1.41(1.17, 1.70)) per 50 μg/m3 increment, respectively). Conclusion Our study found that plasma TMAO level would alter over the course of pregnancy. The major role of TMAO in PE development might be in the accelerating process not in the initiation.

Abstract
Objective PPARγ is a ligand-binding transcription factor that has been reported to be implicated in lipid metabolism, immune function, and cellular growth and differentiation. It has been suspected to play a role in the pathophysiology of preeclampsia, although the mechanism is yet to be elaborated. This study aims to investigate the expression of PPARγ in early onset preeclampsia (EOPE), late onset preeclampsia (LOPE), and normal pregnancy. We conducted this study using primary trophoblastic cell culture incubated with serum from EOPE, LOPE, and normal pregnancy. The expression of PPARγ in these cells was analyzed using Western Blot. Statistical analysis was performed using one-way ANOVA and Bonferroni’s post hoc test. p < 0.05 is considered significant. Results Serum from normal pregnant women and EOPE did not induce any difference in the expression of PPAR-γ (p > 0.05). In contrast, expression of PPAR-γ was increased in those cells induced by serum from LOPE (p < 0.001). Therefore, we conclude that hypothetically PPAR-γ might play role in the pathophysiology of LOPE but not in EOPE. Other possibility is the activity of PPAR-γ in EOPE is inversely correlated with its expression, therefore the high enzymatic activity of PPAR-γ is tightly regulated by attenuating its expression.

Abstract
Background Previous studies showed that thyroid dysfunction in women with gestational hypertension could negatively affect maternal and fetal outcomes. In this study, we aimed to investigate whether thyroid dysfunction assessed in the second half trimester contributed to neonatal outcomes of pregnancy in different subtypes of gestational hypertension disease. Methods We performed a retrospective case-control study and collected data from 135 singleton pregnant women with gestational hypertension disease and their offspring who delivered in Renmin Hospital of Wuhan University from January 2015 to June 2017. We classified the patients based on the severity of the preeclampsia into three groups: pregnant induced hypertension (PIH), mild preeclampsia (MPE) and severe preeclampsia (SPE). Based on the onset time of preeclampsia, we classified the patients into PIH, early onset preeclampsia (EPE) and late onset preeclampsia. Demographic data and levels of thyroid hormones, as well as the adverse maternal and neonatal outcomes were collected from Electronic Medical Records. Logistic regression was used to estimate the associations between thyroid dysfunction and neonatal outcomes in these patients. Results Gestational weeks and neonatal birthweight were significantly lower, while incidence of preterm birth was significantly higher in the SPE and EPE groups than those in the PIH group (P < 0.001). Thyroid dysfunction was more frequent in the SPE group than in the MPE group (P = 0.01). Incidences of both preterm birth and low birth weight were significantly higher in patients with thyroid dysfunction (P = 0.008, P = 0.047 respectively). After adjustment, both severity of gestational hypertension (OR = 4.360, 95%CI [2.050, 9.271], P < 0.001; OR = 4.023, 95%CI [1.933, 8.372], P < 0.001) and thyroid dysfunction (OR = 3.011, 95%CI [1.248, 7.262], P = 0.014; OR = 11.306, 95%CI [1.040, 122.889], P = 0.046) were associated with higher risk of preterm birth and low birth weight, while the onset time of preeclampsia (OR = 0.031, 95%CI [0.009, 0.110], P < 0.001; OR = 0.097, 95%CI [0.033, 0.282], P < 0.001) was negatively associated with the risk of preterm birth and low birth weight. Conclusion Severe and early onset preeclampsia, as well as thyroid dysfunction are associated with higher risk of preterm birth and low neonatal birth weight. Therefore, our data suggest that monitoring thyroid hormones in women with preeclampsia might help to predict adverse neonatal outcomes.

Abstract
OBJECTIVES Maternal leucocytes play an important role in the pathogenesis of preeclampsia (PE). Circulating microRNAs (miRNAs) are small, noncoding RNA molecules. The purpose of this study was to investigate miR-518b, miR-155-5p, and miR-21-3p in the peripheral blood leukocytes of patients with PE, compared to controls. STUDY DESIGN Using real-time quantitative PCR method, the selected miRNAs which have been associated with PE were examined from early- onset PE (EOPE) (<34 weeks) (n = 48), late- onset PE (LOPE) (≥34 weeks) (n = 48), total cases of PE (n = 96), and healthy controls (n = 52). MAIN OUTCOME MEASURES The relative expression of the target miR in patient samples was compared to the calibrator and the results were expressed as relative quantification values. RESULTS Gestational age (GA) was significantly different between PE and controls. Univariate logistic regression analysis adjusted for GA at blood draw were fit to compare miR-518b, miR-155-5p, and miR-21-3p between PE and controls. The expression of miR-518b, miR-155-5p, and miR-21-3p were not significantly different in PE, compared to controls. The expression of miR-518b was upregulated in the EOPE and LOPE group, compared to controls, and the area under the receiver operating characteristic curve (AUC) of miR-518b was 0.65 and 0.62, respectively. miR-518b was positively correlated with WBC count, platelet count, serum levels of AST, ALT, LDH in EOPE. miR-21-3p expression level was negatively correlated with body mass index at blood draw and systolic blood pressure in the LOPE group. CONCLUSIONS Increased miR-518b expression levels were found to be associated with EOPE and LOPE.

Abstract
AIM Disturbed placentation results in pregnancy complications like preeclampsia. Placental development is influenced by apoptosis during trophoblast differentiation and proliferation. Increased oxidative stress upregulates placental apoptosis. We have earlier reported increased oxidative stress, lower omega-3 fatty acids and vitamin E levels in women with preeclampsia. Current study examines effect of maternal omega-3 fatty acids and vitamin E supplementation on apoptotic markers across gestation in a rat model of preeclampsia. MAIN METHODS Pregnant Wistar rats were randomly assigned to control; early onset preeclampsia (EOP); late onset preeclampsia (LOP); early onset preeclampsia + omega-3 fatty acid + vitamin E supplementation (EOP + O + E) and late onset preeclampsia + omega-3 fatty acid + vitamin E supplementation (LOP + O + E) groups. Animals (Control, EOP, EOP + O + E) were sacrificed at d14 and d20 of gestation while animals (LOP, LOP + O + E) were sacrificed at d20 to collect blood and placentae. Protein and mRNA levels of apoptotic markers were analyzed by ELISA and RT-PCR respectively. KEY FINDINGS Protein levels of proapoptotic markers like Bcl-2 associated X-protein (BAX) (p < 0.05), caspase-8 and 3 (p < 0.01 for both) and malondialdehyde (p < 0.01) were higher only in the EOP group as compared to control. However, the antiapoptotic marker, B cell lymphoma 2 (Bcl-2) protein levels were lower in both the subtypes of preeclampsia (p < 0.01 for both). SIGNIFICANCE Our findings suggest that supplementation was beneficial in reducing the caspase-8 and 3 in early onset preeclampsia but did not normalize BAX and Bcl-2 levels. This has implications for reducing placental apoptosis in preeclampsia.

Abstract
Goal: Our aim was to determine whether alterations in serum serglycin and agrin levels in early-onset preeclampsia (EOPE) are useful in predicting adverse perinatal outcomes such as fetal growth restriction (FGR), intrauterine fetal demise (IUFD), preterm delivery and/or neonatal unit admission. Materials and Methods: A prospective case-controlled study enrolled 88 pregnant patients (44 EOPE and 44 controls). Maternal serum serglycin and agrin levels were determined before the 34th gestational week by enzyme-linked immunosorbent assay. Results: Compared with controls, women with EOPE had significantly higher serglycin and agrin levels (p = .018; p = .048). Multivariable logistic regression analysis revealed serglycin was independently associated with FGR in EOPE (OR 0.866; 95% CI 0.779-0.953). Agrin was independently associated with IUFD in EOPE (OR 0.757, 95% CI 0.636-0.879). Conclusions: The current study suggests that increased maternal serum serglycin is associated with FGR, and increased maternal serum agrin is associated with IUFD in EOPE.

Abstract
Objective This study aimed to compare the first trimester complete blood count (CBC) indices of pregnancies complicated by early-onset preeclampsia (EOPE) or late-onset preeclampsia (LOPE). Material and Methods A retrospective case-control study was conducted with 186 patients. Patients were classified into three subgroups: EOPE, LOPE, and control groups. First trimester CBC results were obtained for each patient. Hemoglobin, hematocrit, red blood cell distribution width, mean corpuscular volume, white blood cell (WBC) count, neutrophil, eosinophil, basophil, lymphocyte, monocyte, mean platelet volume, platelet distribution width, plateletcrit, and platelet count were compared. The neutrophil lymphocyte ratio was calculated by dividing the absolute lymphocyte count by the absolute neutrophil count. The platelet lymphocyte ratio was calculated by dividing the absolute lymphocyte count by the absolute platelet count. Results The total number of cases was 21, 42, and 123, in the EOPE, LOPE, and control groups, respectively. There were statistically significant differences in the total WBC and neutrophil counts between the three groups (both p<0.05). WBC and neutrophil counts were found to be highest in the EOPE group, and the LOPE group had higher levels compared with controls. The optimal cut-off values to predict EOPE for WBC and neutrophil counts were 9.55×103/ μL (sensitivity 71.4% and specificity 70.7%) and 6.45×103/μL (sensitivity 66.7% and specificity 74.8%), respectively. Conclusion Increased first trimester WBC and neutrophil counts may be predictive for EOPE.

Abstract
Objective: To investigate the relationship of STOX1expression and pathogenesis of early onset preeclampsia. Methods: 65 cases of preeclampsia women who delivered in Shanghai Pudong Hospital from October 2015 to June 2018, were recruited, which included 31 cases with early onset preeclampsia (early onset group, gestational week<34 weeks) and 34 patients with late onset preeclampsia (late onset group, gestational week ≥34 weeks). 34 cases women who received caesarean section because of pelvic structural deformities, breech presentation, macrosomia and social factors were included as the control group(gestational week ≥34 weeks) were selected as control group.The expression and localization of STOX1 mRNA and protein in placenta of three groups of maternal were evaluated by immunohistochemistry SP, RT-qPCR and Western blotting. Results: (1) The expression of STOX1 in placenta mainly distributed in the cytoplasm of placental syncytiotrophoblasts, cytotrophoblasts, vascular endothelial and mesenchymal cells, a few in the cell nucleus.The staining intensity of STOX1 in early onset group was significantly stronger than that in late onset group, the staining intensity of the late onset group was similar to that of the control group. The positive expression rates of STOX1protein in early onset group, late onset group and control group were 96.8%(30/31), 70.6%(24/34), 67.6%(23/34) respectively, which was higher in early onset group than that in late onset group(P=0.005). There was no statistical difference of STOX1 level between the late onset group and the control group(P=0.793). (2)Relative expression of STOX1 mRNA in early onset group, late onset group and control group were 0.054 3±0.003 5,0.037 5±0.000 7,0.035 2±0.000 4 respectively, which was significantly higher in early onset group than that in late onset group(P<0.05), while there was no statistical difference between the late onset group and the control group(P>0.05).(3)Relative expression level of STOX1 protein in early onset group, late onset group and control group were 0.78±0.04,0.59±0.020 and 0.54±0.018 respectively, which is higher in early onset group than that in late onset group(P<0.05). There was no statistical difference of STOX1 level between the late onset group and the control group(P>0.05). Conclusions: The pathogenesis of early onset and late onset preeclampsia may be different. Up-regulated expression of STOX1 in placenta may be associated with the pathogenesis of early onset preeclampsia.

Abstract
OBJECTIVES To better understand the effects of maternal age on birth outcomes among preeclampsia (PE) patients, we examined the rates of preterm birth, low birthweight, and small for gestational age (SGA) among different age groups and explored whether maternal age was associated with those adverse outcomes. STUDY DESIGN This is a multicenter retrospective study. Data from 1128 PE patients, including 580 with early onset PE and 548 with late onset PE, were analyzed. MAIN OUTCOME MEASURES Maternal age was categorized into three groups: <25, 25-34, and ≥35 years. The outcome variables were preterm birth (<37 weeks; subgroups: <28 weeks, 28-33 weeks, and 34-36 weeks), low birthweight (<2500 g; subgroups: <1500 g and <1000 g), and SGA. Logistic regression was used to analyze the associations between maternal age groups and outcomes. RESULTS In early onset PE, compared with maternal age 25-34 years, maternal age ≥35 years was associated with elevated risk for preterm delivery before 28 weeks, and maternal age <25 years was associated with elevated risk for low birthweight and SGA. When the analysis was restricted to women who underwent cesarean section, elevated risks for preterm birth and/or low birthweight were observed for women younger than 25 years in both early and late onset PE. CONCLUSIONS Among women with PE, maternal age <25 years could add risk to preterm birth and/or low birthweight. For women with early onset PE, maternal age ≥35 years is a risk factor for preterm delivery before 28 weeks.

Abstract
INTRODUCTION AND AIM Exosomes are a subtype of extracellular vesicle (20-130 nm) released by biological cells under normal and pathological conditions. Although there have been reports of circulating exosomes in normal pregnancy, the relevance of placental-derived exosomes in normal and abnormal pregnancies still needs to be elucidated. The aim of this study was to quantify total and placental-derived exosomes in maternal plasma from normal (N), early onset- and late onset-preeclampsia (PE). METHOD Plasma samples were obtained from pregnant women in the third trimester, for the isolation of exosomes by differential ultracentrifugation. Total exosomes were quantified using nanoparticle tracking analysis and immuno-reactive exosomal CD63 quantification. Placental-derived exosomes were quantified using placental alkaline phosphatase (PLAP) as a specific marker. The contribution of placental-derived exosomes to total exosomes in maternal plasma was determined by the ratio of PLAP+ exosomes to CD63+ exosomes. RESULTS The concentration of total exosomes significantly increased in early onset-PE and late onset-PE compared to N (≤33 weeks) and N (≥34 weeks). The relative concentration of placental-derived exosomes significantly increased in early onset-PE but decreased in late onset-PE compared to N. The ratio of PLAP+ exosomes to total number of exosomes significantly decreased in early onset-PE and late onset-PE. A positive correlation between total and placental-derived exosomes were obtained in N (≤33 weeks: Pearson's r = 0.60, ≥34 weeks: Pearson's r = 0.67) and early onset-PE (Pearson's r = 0.51, p < 0.05) with the inverse in late onset-PE (Pearson's r = -0.62, p < 0.01). CONCLUSION The differences in the contribution of placental-derived exosomes to total exosomes in maternal circulation suggests a possible pathophysiological role of placental-derived exosomes in pre-eclampsia.

Abstract
INTRODUCTION Preeclampsia is a leading cause of maternal and perinatal mortality and morbidity, but signs and symptoms are non-specific and may vary. The root cause is imbalance of circulating angiogenic factors of placental (syncytiotrophoblast) origin, with consequent low levels of placental growth factor (PlGF) which may aid in diagnosis and prediction of disease. AIMS AND OBJECTIVES To study the incidence of women at risk of developing early-onset preeclampsia by plasma placental growth factor biomarker assay in high-risk patients, to assess the maternal outcome in patients with PlGF values below cutoff for presenting gestational age, to calculate sensitivity, specificity, positive predictive value and negative predictive value of PlGF assay in predicting preeclampsia and to conclude whether PlGF biomarker assay can be an effective screening test in high-risk patients for prediction of early-onset preeclampsia. MATERIALS AND METHODS The study was carried out in the Department of Obstetrics and Gynecology at a tertiary care center. It is a prospective study, and study period extended from April 2012 to October 2013. One hundred pregnant women with 20- to 34-week gestational age with possible high risk of developing preeclampsia attending the antenatal clinics and high-risk OPDs were screened in the present study after explaining the nature of the study. PLGF concentration was quantitated using plasma and processed in Triage kit device (fluorescence immunoassay device). PLGF concentration was categorized against a specific range for specific gestation, and values below the range or <12 pg/ml were considered screened positives. The cases were followed up till delivery. RESULTS Twenty-two cases were screened positive, of which 20 developed preeclampsia with a strong positive prediction value of more than 90 %. CONCLUSION PLGF is a strong predictor and a useful assay for early-onset preeclampsia.

Abstract
OBJECTIVE Despite the absence of a complete physiologic-pathologic understanding, common accepted theory for development of preeclampsia is incomplete trophoblastic invasion leading to failed uterine and spiral arteriolar remodeling, causing maternal vascular endothelial dysfunction by secreted molecules in response to decreased placental perfusion, placental hypoxia, and ischemia. Placental angiogenesis is especially ineffective in early onset preeclampsia and fetal morbidity/mortality rates are higher because of further decreased blood flow. In this study, we aim to compare the maternal and umbilical cord blood levels of hypoxia-inducible transcription factor-1α (HIF-1α), which is believed to regulate hypoxia-related transcriptional responses, to play role in activating genes for initial phases of placental development and angiogenesis and a physiologic vasodilator molecule nitric oxide (NO) in normal, early and late onset preeclamptic pregnant women. METHODS Pregnant women who were diagnosed with preeclampsia (early onset ≤34 weeks; late onset >34 weeks) and delivered in our clinic were enrolled for this prospective case-controlled study. Pregnant women without preeclampsia were recruited as control group. HIF-1α and NO levels in maternal and umbilical cord blood measured and compared among groups. FINDINGS A total of 46 cases were enrolled for this study, including 25 preeclamptic (13 in the early onset group and 12 in the late onset group) and 21 normal pregnant women in the control group. Comparison of preeclampsia group to controls revealed higher maternal blood HIF-1α levels in the control group, however higher umbilical cord NO levels in the preeclampsia group (p < 0.05 and p < 0.001, respectively). In a second analysis, when compared to control group, both early and late onset preeclampsia subgroups were found to have higher umbilical cord blood NO levels (p < 0.001). RESULTS In this study, we observed lower maternal blood HIF-1α levels and higher umbilical cord NO levels in preeclampsia group than controls. These findings suggest that umbilical cord blood NO levels in pregnant women with preeclampsia increase in response to hypoxia. However, lower HIF-1α levels in preeclampsia group can be due to our limited number of cases and we think that there is a need for further studies with larger sample size.

Abstract
INTRODUCTION Preeclampsia affects about 3% of pregnancies and the placenta is believed to play a major role in its pathophysiology. Lately, the role of the placenta has been hypothesised to be more pronounced in preeclampsia of early (<34 weeks) rather than late (≥ 34 weeks) onset. (31)P Magnetic Resonance Spectroscopy (MRS) enables non-invasive, in vivo studies of placental metabolism. Our aim was to study placental energy and membrane metabolism in women with normal pregnancies and those with early and late onset preeclampsia. METHODS The study population included fourteen women with preeclampsia (five with early onset and nine with late onset preeclampsia) and sixteen women with normal pregnancy (seven with early and nine with late pregnancy). All women underwent a (31)P-MRS examination of the placenta. RESULTS The phosphodiester (PDE) spectral intensity fraction of the total (31)P signal and the phosphodiester/phosphomonoester (PDE/PME) spectral intensity ratio was higher in early onset preeclampsia than in early normal pregnancy (p = 0.03 and p = 0.02). In normal pregnancy the PDE spectral intensity fraction and the PDE/PME spectral intensity ratio increased with increasing gestational age (p = 0.006 and p = 0.001). DISCUSSION Since PDE and PME are related to cell membrane degradation and formation, respectively, our findings indicate increased cell degradation and maybe also decreased cell proliferation in early onset preeclampsia compared to early normal pregnancy, and with increasing gestational age in normal pregnancy. CONCLUSIONS Our findings could be explained by increased apoptosis due to ischaemia in early onset preeclampsia and also increased apoptosis with increasing gestational age in normal pregnancy.
