Methylation and expression of imprinted genes in circulating extracellular vesicles from women experiencing early onset preeclampsia.

Introduction: Preeclampsia (PE) is a pregnancy complication marked by high blood pressure, posing risk to maternal and fetal health. "Genomic imprinting", an epigenetic phenomenon regulated by DNA methylation at Differently Methylated Regions (DMR's), influences placental development. Research on circulating extracellular vesicles (EVs) in PE suggests them as potential source for early biomarkers, but methylation status of EV-DNA in Preeclampsia is not reported yet.

Differential proteomics of circulating extracellular vesicles of placental origin isolated from women with early-onset preeclampsia reveal aberrant innate immune and hemostasis processes.

Problem: Early-onset preeclampsia (EOPE) is a severe gestational hypertensive disorder with significant feto-maternal morbidity and mortality due to uteroplacental insufficiency. Circulating extracellular vesicles of placental origin (EV-P) are known to be involved in the pathophysiology of EOPE and might serve as an ideal reservoir for its specific biomarkers. Therefore, we aimed to characterize and perform comparative proteomics of circulating EV-P from healthy pregnant and EOPE women before delivery.

Navigating portal hypertension: Unlocking safe passage to healthy pregnancy in EHPVO.

Background And Aims: Pregnancy is associated with hyperdynamic circulatory state and increased risk of portal hypertension related complications in patients with extra-hepatic portal vein obstruction (EHPVO). We aim to study the impact of EHPVO on pregnancy-related outcomes with focus on subset of patients with UGIB (upper GI bleed).

Methods: Retrospective analysis of obstetric, maternal and neonatal outcomes of patients with EHPVO registered between January 2006 and December 2022.

Incidence & factors influencing maternal near miss events in tertiary hospitals of Maharashtra, India.

Background & Objectives: Government of India (GoI) released operational guidelines for maternal near miss-review (MNM-R) in 2014 for use by programme managers of public health system to assist them for conducting MNM-R. The objective of the present study was to review the incidence and factors influencing MNM events in two tertiary hospitals of Maharashtra, India, as per the operational guidelines of the GoI released in 2014 and identify delays based on three-delay model to prevent such events in future.

Methods: This prospective observational study was conducted in two tertiary hospitals of Maharashtra, from July 2018 to November 2020.
