Patients And Methods: Herein we report the case of a 37 year old pregnant women with Marfan syndrome with dilatation of the aorta ascendens of 42 mm preconceptionAl. The dilatation remained stable until 34 weeks of gestation when a aortic dissection (De Bakey type I) occurRed rapidly. The patient underwent a cesarean section and hysterectomy, followed by surgery of the aorta asc. by means of implantation of a valved graft immediately.
Conclusions: The criteria of a dilatation of the aorta ascendens < 40 mm does not identify reliably those patients who are at risk of dissection during pregnancy. A interdisciplinary approach together with obstetricians, cardiologists and cardiac surgeons is mandatory in all cases of Marfan syndrome and pregnancy.

Current efforts investigating parturition timing mechanisms have focused on the proximal triggers of labor onset generated in late pregnancy. By studying the delayed parturition phenotype of mice with uterine fibroblast deficiencies in the histone H3K27me3 demethylase KDM6B, we provide evidence that parturition timing is regulated by events that take place in early pregnancy. Immediately after copulation, uterine fibroblasts engage in a locus-specific epigenetic program that abruptly adjusts H3K27me3 levels across their genome.

Objectives: This study aimed to dissect the aetiological subgroups of postpartum haemorrhage (PPH) that occur after vaginal delivery in women with full-term singleton pregnancies. Our goal was to craft and validate predictive models to guide clinical decision-making and optimise resource allocation.
Design: A retrospective cohort study.

Pregnancy-related spontaneous coronary artery dissection (P-SCAD) is a life-threatening condition that occurs during or after pregnancy, is rare and can be overlooked. It is one of the most important causes of pregnancy-related acute myocardial infarction. A 25-year-old female patient was admitted with a complaint of chest pain in her 37th week of pregnancy.

Background: Acute myocardial infarction during pregnancy is a rare condition with an incidence of 1 to 10 per 100,000 deliveries. ST-elevation myocardial infarction (STEMI) is dominating the clinical presentation. It is estimated that 29% of the patients had normal coronary arteries, and hyperthyroidism may be associated with coronary vasospasm.

Problem: Although it is still uncertain whether Severe Acute Respiratory Coronavirus (SARS-CoV-2) placental infection and vertical transmission occur, inflammation during early pregnancy can have devastating consequences for gestation itself and the growing fetus. If and how SARS-CoV-2-specific immune cells negatively affect placenta functionality is still unknown.
Method Of Study: We stimulated peripheral blood mononuclear cells (PBMCs) from women of reproductive age with SARS-CoV-2 peptides and cocultured them with trophoblast spheroids (HTR-8/SVneo and JEG-3) to dissect if SARS-CoV-2-activated immune cells can interfere with trophoblast functionality.
