Active clinical trials for "Fetal Death"

Correlation between the presence of intracellular viruses/bacteria and the incidence of miscarriage during the first trimester of pregnancy.

The aim of this project is to assess the feasibility of a new local post mortem procedure at Besançon University Hospital : Virtopsy+, magnetic resonance (MR) imaging with tissue sampling of the fetus and newborns.

This is a randomised controlled trial designed to investigate the impact of a brief-cognitive task based intervention on intrusive memories, mental health symptoms and daily functioning, in women following an early pregnancy loss.

The primary objective of this study is to demonstrate that plasma concentrations of nucleosomes and free DNA differ between three groups: pregnant patients with complications typical of placental insufficiency or venous thrombosis (group P), healthy women (Group T1) and healthy pregnant women (Group T2).

Women presenting to Washington Hospital Center with fetal loss would be offered participation in the study. The objective is to determine if ccffDNA obtained from maternal blood is present in the setting of missed abortion or fetal demise. The investigators primary hypothesis is that cell free fetal DNA will be present in maternal blood in the presence of a failed pregnancy.

Establish a multi-platform detection system for neutrophil extracellular traps in blood and tissues, and evaluate the detection performance; Comparing the expression levels of neutrophil extracellular traps in peripheral blood and decidua of patients with antiphospholipid antibody-induced pregnancy loss and normal control group; Comparing the expression levels of neutrophil extracellular traps in peripheral blood and decidua of mice with antiphospholipid antibody-induced pregnancy loss and normal control group; After treatment of antiphospholipid antibody-induced mouse abortion model with metformin,the effect of metformin on embryo loss rate and viable embryo body weight was observed.

Congenital and acquired thrombophilia were identified as risk factors for thrombosis in systemic vessels.Thrombophilias have also been recently found to be associated with preeclampsia, intrauterine fetal growth restriction (IUGR), placental abruption, intrauterine fetal death (IUFD) and repeated pregnancy loss.These severe pregnancy complications are thought to result from thrombotic events occurring in the uteroplacental circulation. Accumulating data have established an association between elevated plasma activity of factor VIII and thrombosis although the mechanism is still not defined and elevated factor VIII activity is now regarded as being equivalent to thrombophilia. We intend to investigatthe association between factor VIII levels and severe pregnancy complications which are considered to result from placental vascular pathology, i.e., preeclampsia, IUGR, placental abruption and IUFD. We hypothezise that the prevalence of elevated factor 8 will be higher among women with pregnancy complications compared to controls.

The Environmental Factors and Embryonic Development Project was set up to investigate environmental exposures and behavioral factors responsible for embryonic dysplasia and gestational complications in pregnant women.

The University Hospital Advanced Age Pregnant (UNIHOPE) Cohort is the major part of the National Key Research and Development Program on Reproductive Health & Major Birth Defects Control and Prevention Project, which is funded by the Ministry of Science and Technology of China. The Project is led by Prof. Zhao Yangyu, from the Department of Gynecology & Obstetrics, Peking University Third Hospital, and the UNIHOPE cohort is led by Prof. Jian-meng Liu, the Co-PI of the Project.

Patients with history of two or more recurrent pregnancy loss (RPL) and no history of living babies who had performed all investigations for recurrent miscarriage (RM) including : laboratory investigation ,trans vaginal ultrasound (TVS) ,autoimmune work up and hystroscopy and all results were free,will be scheduled for three dimensional trans-vaginal ultrasound (3D TVS) in the midluteal phase for measuring the impedance of uterine artery blood flow( by two dimensional Power Doppler TVS).Also by using 3D power Doppler the sub-endometrial blood flow will be assessed. In addition to the thickness of Junctional Zone (JZ) by using coronal view of 3 D TVS. To be compared with patients who had at least one full term living baby through normal vaginal delivery with no history of early pregnancy loss.
