Hypertension in Pregnancy最新文献

Objective: To assess the effectiveness of interactive education tools for hypertension in pregnancy.Two interactive education tools were introduced.Methods: Pregnant women with hypertension completed questionnaires before (Pre-I) and after)Post-I) the intervention.Providers rated satisfaction and effectiveness of the education methods.Results: The Post-I group (N=45) showed slight improvement on both Perceived (4.5±0.7) and Actual knowledge (2.2 ± 1.0) compared to the Pre-I group (N=45; Perceived: 4.2±1.0; Actual: 1.7±1.3; p<.05) .Providers reported higher satisfaction after the intervention (2.6±1.1 vs 4.1±0.7; p <.001).iscussion: The intervention increased patients' knowledge and providers rating of patient knowledge, and decreased the time needed for patient education.

Objective: This study aimed to investigate the efficiency of the soluble Fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio in predicting preeclampsia (PE) within 4 weeks in twin pregnancies.Methods: Seventy-eight women with serum angiogenic markers measured at 28 + 0 to 30 + 6 weeks of gestation were enrolled. A receiver-operating characteristic curve was used to determine the sFlt-1/PlGF ratio threshold to predict PE.Results: A cutoff value for the sFlt-1/PlGF ratio of 22.2 predicted PE presence within 4 weeks.Conclusion: An sFlt-1/PlGF ratio of ≤22.2 is potentially indicative of PE absence within 4 weeks in twin pregnancies.

Introduction: Apoptosis is involved in pathogenesis of Pre-eclampsia (PE), further research is needed to determine its molecular mechanism.

Methods: The study recruited two groups (controls; 09, PE; 11). Biochemical tests, RT-PCR and ELISA were employed for analysis of genes and MicroRNAs (miRNA). Bioinformatics tools were employed for interactomics analysis.

Results: There was increased apoptosis in maternal placental tissue (MPT) and Maternal Blood Cells (MBC) as demonstrated by expression of CASP3 and NF-κB1. miR-146-5p and 187-5p were downregulated in MBC and MPT but upregulated in fetal placental tissue (FPT)..

Discussion: An increased apoptosis in MBC and MPT is a significant contributory factor for PE in pregnancy, while FPT is immune to the aforementioned effects.

Introduction: Interleukin-25 is a Th2 interleukin and has been shown to influence cell behavior. This study aims to illustrate its affection on extravillous trophoblasts function and association with PE. Methods qPCR and immunohistochemistry demonstrate IL-25 and IL-17RB expression. CCK-8 test and transwell were to access the behavior of HTR8 in the presence or absence of IL-25, IL-25 neutralization antibody. Results EVTs and HTR8 express IL-25 and IL-17RB. IL-25 promotes proliferation and invasion (p< 0.05),which was abolished in the presence of IL-25Ab (p< 0.05). Conclusion: IL-25 may contribute to promote trophoblast invasion and proliferation and abnormal decline of IL-25 might be associated with PE.Methods: qPCR and immunohistochemistry (IHC) were used to demonstrate IL-25 and its receptor IL-17RB expression in primary human trophoblasts of normal first- and third- trimester, as well as third-trimester of PE. CCK-8 test and transwell invasion system in vitro were applied separately to access the behavior of trophoblast cell line (HTR8) in the presence or absence of IL-25, IL-25 neutralization antibody (IL-25 Ab).Results: EVTs and HTR8 express IL-25 and IL-17RB. The expressions increase in third-trimester during normal pregnancy. In PE, both of IL-25 and IL-17RB expressions decrease (p< 0.05). IL-25 for 24 h promoted HTR8 proliferation and invasion (p< 0.05). The effect was abolished in the presence of IL-25Ab (p< 0.05).Conclusion: This study demonstrates that IL-25 may contribute to promote trophoblast invasion and proliferation and abnormal decline of IL-25 might be associated with PE.

Objective: The aim of this study was to explore the expression and effects of tumor necrosis factor alpha (TNFα) in maternal endothelial cells in preeclampsia (PE).Methods: Expression levels in primary microvascular endothelial cells (MVEC) isolated from patients with severe preeclampsia (PE) and normal pregnancies were determined by RT-qPCR with or without treatment of TNFα and inhibitors for downstream signaling.Results: PE MVEC exhibited increased basal TNFα expression. TNFα treatment increased TNFα, VCAM, and endocan expression in MVEC.Conclusion: TNFα expression is increased in PE MVEC and the treatment of these cells with exogenous TNFα modifies their gene expression.

Objective: We investigated, via systematic review and meta-analysis, whether multiple sclerosis (MS) is associated with the risk of preeclampsia (PE).Methods: From the eligible studies, we pooled odds ratios (ORs) and confidence intervals (CIs) of PE for pregnant women with MS compared with pregnant women without it using the fixed-effects model. The I² measured heterogeneity between studies.Results: Eight eligible studies (9 cohorts) were included. Pregnant women with MS had no excess risk of PE compared with pregnant women without MS (pooled OR = 0.99, 95% CI: 0.89, 1.09; I² = 0.00%).Conclusion: MS is not associated with PE.

Objective: To evaluate of COVID-19 disease in pregnant women and its association with hypertensive disorders of pregnancy.Design: Retrospective Cohort StudySetting: Multicenter study from a large metropolitan hospital systemMethods: Patients who tested positive for COVID-19 during their pregnancy and delivered were compared to the three subsequent deliveries of patients who tested negative (controls). We evaluated the impact of COVID-19 on the development of hypertensive disorders of pregnancy.Results: Compared with pregnancies negative for SARs-CoV-2 infection, maternal SARs-CoV-2 infection was associated with an increased risk for hypertensive disorders of pregnancy (OR 3.68, 95% CI 1.67 - 8.10).Tweetable AbstractPatients who test positive for COVID-19 during their pregnancy are at increased risk of developing a hypertensive disorder of pregnancy. Earlier SARs-CoV-2 infection results in an increased risk of developing a hypertensive disorder.

Background: This study aimed to investigate the prognostic value of N-terminal B-type natriuretic peptide (NT-proBNP) in pregnancies with isolated chronic hypertension (HT).Method: 34 pregnant women with chronic HT and 40normotensive controls were enrolled. The association between plasma NT-proBNP levels obtained in the first trimester and perinatal complications were evaluated.Results: NT-proBNP levelsstrongly predicted low birth weight (AUC=0.842, p<0.001). NT-proBNP and birth weight were negatively correlated (r= -0.323, p=0.005). NT-proBNP was found to be an individual determinant of low birth weight in univariate analysis (OR:1.03; 95%CI:1.01-1.04).Conclusion: NT-proBNP levels can be useful to predict low birth weight in pregnancies with chronic HT.

Objective: To determine association between IL-32 gene polymorphism, and serum levels of IL-32 and susceptibility to preeclampsia (PE).

Methods: The frequency of IL-32 rs9927163 and rs4786370 polymorphisms was determined by PCR-RFLP. Also ELISA was used to determine the levels of serum IL-32.

Results: Regarding rs4786370 C/T SNPs, the frequencies of CT, TT genotypes, and T allele were shown to be higher in the PE patients. IL-32 serum level significantly increased in the PE patients.

Conclusion: Variety of allele and genotype IL32 rs4786370 as well as a rise in serum level of IL-32 can be regarded as a risk factor for PE.

Introduction: A potential manner to lower the morbidity with the hypertensive disoreders of pregancy is to explore the time of day of delivery.

Objective: To compare composite neonatal adverse outcomes among term women with hypertensive disorders.

Methods: This population-based cohort study used the U.S. vital statistics dataset from 2013 to 2017. Time of delivery was categorized into three shifts. The primary outcome was composite neonatal adverse outcome..

Results: Compared to neonates delivered at the first shift, the risk of composite neonatal adverse outcome was higher at the third shift (aRR = 1.19, 95% CI = 1.13-1.25).

Conclusion: the risk of composite neonatal adverse outcome is higher if the delivery occurs at the third (23:00-7:00) shift.
