Circ_0008440 Inhibits Proliferation and Promotes Apoptosis of Trophoblast Cells through the miR-194-5p/PFKFB2 Axis.

Preeclampsia (PE), an idiopathic hypertensive disorder that arises during pregnancy, poses a serious threat to the health of expectant mothers. Human chorionic trophoblast cells (HTR-8/SVneo) are associated with the development of PE. It has been reported that circ_0008440 expression is abnormally increased in the placental tissues of PE patients.

Amlodipine versus Nifedipine ER for the Management of Postpartum Hypertension: A Noninferiority Randomized Controlled Trial.

Background: Postpartum hypertension is an increasingly prevalent problem and optimizing its treatment is imperative in reducing maternal morbidity and improving long-term health outcomes. Despite this, data on treatment of postpartum hypertension is limited. While most available studies focus on labetalol and nifedipine ER, these medications are not frequently used for hypertension treatment in the non-obstetric setting.

The role of placenta Hofbauer cells during pregnancy and pregnancy complications.

Placental Hofbauer cells (HBCs) are specialized macrophages present in the human placenta that play a crucial role in maintaining a healthy pregnancy. These cells are derived from the fetal mesoderm and are responsible for various functions, including immune regulation, angiogenesis, and nutrient transport. In normal pregnancies, HBCs primarily exhibit an M2 or immunomodulatory phenotype, which helps maintain a tolerant and anti-inflammatory environment at the maternal-fetal interface.

Inpatient versus outpatient management of gestational hypertension or preeclampsia without severe features.

Objective: To comparematernal and neonatal outcomes in patients diagnosed with gestational hypertension or preeclampsia without severe features by outpatient versus inpatient management.

Materials And Methods: This was a single center, retrospective, cohort study of patients with hypertensive disorder of pregnancy (HDP) before 37 weeks' gestation from January 2014 to March 2022. Patients were triaged to inpatient or outpatient management at the discretion of their obstetrician.

Glycosylated fibronectin as a biomarker for preeclampsia and preeclampsia-related complications.

Study Design: Secondary analysis of a prospective cohort study (n = 524) with suspected preeclampsia (control), gestational hypertension (GH), or confirmed preeclampsia/hemolysis, elevated liver enzymes and low platelets syndrome (PE/HELLP).

Main Outcome Measures: GlyFn levels in PE/HELLP versus control and GH.

Edaravone Protects Trophoblast Cells From Hypoxic Injury in Preeclampsia: Inhibition of the PI3K/AKT Pathway as a Promising Therapeutic Approach.

Objective: Preeclampsia (PE) is a multifaceted medical condition that manifests during pregnancy, characterized by hypertension and damage to multiple organs. In PE, the placenta's impaired functionality leads to continuous hypoxia in placental tissues, which is considered the primary cause of the condition. Inhibition of hypoxia-induced injury in trophoblast cells presents a potential therapeutic strategy for PE.

Fetomaternal outcome in preeclampsia and eclampsia with posterior reversible encephalopathy syndrome.

Introduction: Preeclampsia and eclampsia are hypertensive disorders of pregnancy associated with significant maternal and fetal morbidity and mortality. Posterior reversible encephalopathy syndrome (PRES) is a neurological complication observed in these conditions, yet its impact on fetomaternal outcomes remains underexplored. The aim of this study is to investigate the association between PRES and fetomaternal outcomes in women with preeclampsia and eclampsia.

Brain and brain blood vessels histological description in autopsies of fetuses/neonates born to mothers with hypertension during pregnancy. A case-control study.

Background: Children born to women with hypertension during pregnancy have a two to threefold increased risk of developing cognitive disorders compared to children born to women without hypertension. However, structural changes in the central nervous system of these children remain poorly understood. We aim to compare the brain histological findings from autopsies of neonates and fetuses born to women with and without hypertension during pregnancy.

Perceived barriers and facilitators of implementing a sustained smartphone-based telemonitoring program for pregnant women at high-risk for pre-eclampsia in the public and private sectors in Pakistan.

Background: In Pakistan, a smartphone-based telemonitoring (TM) program (Raabta) has been designed to support pregnant women with high risk for preeclampsia (HRPE) in Pakistan. However, implementing TM interventions is often challenging, particularly in low-resource settings, given the complexity of healthcare environments and variations in public and private health sectors. This study explores the potential barriers and facilitators for a sustained implementation of the Raabta program in public and private sector hospitals in Pakistan.

Association Between Placental Pathology and Early-Onset Fetal Growth Restriction: A Systematic Review.

Fetal growth restriction (FGR) is defined as the failure of the fetus to achieve its genetically determined growth potential. Our aim is to compare the placental lesions present in early-onset fetal growth restriction with that of late-onset FGR. We performed a systematic review according to the PRISMA guideline.

The safety profile of usage of glucagon-like peptide-1 receptor agonists in pregnancy: A pharmacovigilance analysis based on the Food and Drug Administration Adverse Event Reporting System.

Aims: The use of (GLP-1 RAs) among pregnant women is escalating, yet safety data remain insufficient. This study aims to comprehensively assess adverse drug reactions (ADRs) associated with GLP-1 RAs in pregnant women using the US Food and Drug Administration Adverse Event Reporting System (FAERS) database.

Methods: FAERS data from 2004 to 2023 were analysed, focusing on pregnant women aged 15-55 years exposed to GLP-1 RAs.

Efficacy of combining aspirin with hydroxychloroquine in pregnancies at high risk for pre-eclampsia: a prospective, multicentre, open-label, single-arm clinical trial, investigator-initiated study (HUGS study).

Introduction: The use of hydroxychloroquine (HCQ) during pregnancies complicated by systemic lupus erythematosus or refractory antiphospholipid antibody syndrome has demonstrated a significant ability to prevent pre-eclampsia (PE). As such, the potential for the administration of HCQ to prevent PE in other high-risk pregnancies is an important clinical research agenda among maternal and fetal medicine specialists. Mechanistically, the anti-inflammatory and immunomodulatory effects of HCQ can offer vascular protection and inhibit the placental dysfunction-associated thrombotic changes underlying the pathophysiology of PE, fetal growth restriction (FGR) and fetal death in utero (FDIU).

Impaired maternal central hemodynamics precede the onset of vascular disorders of pregnancy at high altitude.

Hypertensive disorders of pregnancy represent an escalating global health concern with increasing incidence in low- to middle-income countries and high-income countries alike. The current lack of methods to detect the subclinical stages of preeclampsia (PE) and fetal growth restriction (FGR), two common vascular disorders of pregnancy, limits treatment options to minimize acute- and long-term adverse outcomes for both mother and child. To determine whether impaired maternal cardiovascular or uteroplacental vascular function precedes the onset of PE and/or FGR (PE-FGR), we used non-invasive techniques to obtain serial measurements of maternal cardiac output (CO), stroke volume (SV), systemic vascular resistance (SVR), as well as uterine and fetal arterial resistance at gestational weeks 10-16, 20-24 and 30-34 for 79 maternal-infant pairs in La Paz-El Alto, Bolivia (3850 m), where the chronic hypoxia of high altitude increases the incidence of PE and FGR.

Special Considerations in the Treatment of Idiopathic Intracranial Hypertension.

Purpose Of Review: To review the management of Idiopathic Intracranial Hypertension (IIH) with co-existing conditions affecting therapy: obesity, sulfa allergy, nephrolithiasis, and pregnancy.

Recent Findings: The IIH-WT trial showed that bariatric surgery is currently the most effective method for obese patients with IIH to lose weight, leading to normalization of CSF pressure in many cases. Allergy to sulfonamide antibiotics does not preclude the use of acetazolamide; rather, penicillin allergy or multiple drug allergies are the strongest predictor of a hypersensitivity reaction.

Case report: Antiphospholipid syndrome revealed by multiple ischemic cerebral strokes in the context of preeclampsia.

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by thrombotic events and pregnancy complications, including preeclampsia. This case report presents a rare manifestation of APS revealed by multiple ischemic cerebral strokes in a patient with severe preeclampsia. A comprehensive review of the literature is included to highlight the clinical presentation, diagnosis, management, and prognosis of APS in the context of preeclampsia.

Evaluation of risk factors for postpartum cerebral venous sinus thrombosis, a multicenter retrospective observational study.

The postpartum period is a well-defined risk factor for cerebral venous sinus thrombosis (CVST). However, it is unclear which patients are at risk for CVST in the postpartum period. Thus, determining some CVST risk factors in postpartum patients may be useful for preventing the disorder in this population.

Vasoactive intestinal peptide induces metabolic rewiring of human-derived cytotrophoblast cells to promote cell migration.

The placenta has an extraordinary metabolic rate with high oxygen consumption. Extravillous cytotrophoblast cells (EVT) metabolism and function are critical to sustain their invasive phenotype supporting fetal development. Deficient EVT function underlies pregnancy complications as preeclampsia (PE) and fetal growth restriction (FGR).

Examination of Piezo1-TRPV4 Dynamics: Implications for Placental Endothelial Function in Normal and Preeclamptic Pregnancies.

Mechanosensation is essential for endothelial cell (EC) function, which is compromised in early-onset preeclampsia (EPE), impacting offspring health. The ion channels Piezo-type mechanosensitive ion channel component 1 (Piezo1) and Transient receptor potential cation channel subfamily V member 4 (TRPV4) are co-regulated mechanosensors in ECs. Current evidence suggests that both channels could mediate aberrant placental endothelial function in EPE.

Living Donation and Pregnancy-Related Complications: State of the Evidence and Call To Action for Improved Risk Assessment.

Living kidney donation and living liver donation significantly increases organ supply to make lifesaving transplants possible, offering survival benefits to the recipients and cost savings to society. Of all living donors, 40% are women of childbearing age. However, limited data exist regarding the effect of donation on future pregnancies and of pregnancy-related complications on postdonation outcomes.

An endogenous aryl hydrocarbon receptor ligand induces preeclampsia-like phenotypes in rats.

Preeclampsia (PE) is a hypertensive disorder during human pregnancy. Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor. Exogenous and endogenous AhR ligands can induce hypertension in male rats and mice.

Placental extracellular vesicles from severe preeclamptic women alter calcium homeostasis in cardiomyocytes: An study.

Women with severe preeclampsia (sPE) exhibit a heightened risk of postpartum cardiovascular disease compared to those with normotensive pregnancies (NTP). While placental extracellular vesicles (EV) play a crucial role in feto-maternal communication, their impact on cardiomyocytes, particularly in the context of sPE, remains unclear. This study investigated the effect of sPE-associated placental EV (sPE-Plex EV) on cardiomyocyte calcium dynamics.
