Active clinical trials for "Abortion, Spontaneous"

Miscarriage is a common event associated with severe psychological and social morbidity, further tormenting in women suffering recurrent pregnancy loss (RPL) by at least three consecutive losses. Ultrasonography and biomarkers have yet to precisely predict viability in pregnancies with symptoms of threatening miscarriage. A novel biomarker Preimplantation Factor (PIF) derived by the developing embryo might be the key factor for this prediction ameliorating the implantation process by promoting a favorable local immune system in the uterus. The investigators aim to establish a prospective early pregnancy cohort (PEP-cohort) that includes women throughout the first trimester by both assisted reproductive technology (ART) and spontaneous conceptions. By a combination of consecutive ultrasonographys and blood samples of known predictors of implantation PIF as a predictor of viability will be evaluated. These data are finally compared to the same data in a retrospective cohort of RPL patients emphasizing the role of PIF. All collected data will be stored in a Research Biobank for the current studies outlined as well as potential future studies of reproductive medicine in the first trimester.

To determine whether screening of pregnant women with history of previous preterm delivery or with premature contractions for bacterial vaginosis using VS-SENSE, and treatment of positive women will reduce the risk of spontaneous preterm birth.

To determine whether there is higher incidence of skewed X chromosome inactivation(SXCI) in the recurrent miscarriage(RM) population compared with normal population, and verify the existing hypothesis of the possible genetic mechanisms underlying the association between SXCI and RM.

Records of women who had Pre-genetic diagnosis (PGD) over the last 3 years will be reviewed and its outcome will be compared to other records of women who had IVF/ICSI without PGD.

This was a retrospective study sharing the experience of women high risk for spontaneous preterm birth managed by Arabin pessary.

Purpose: To study the impact of endometriosis on subsequent pregnancy and delivery. Methods: retrospective analysis by questionnaire / interview of cases (endometriosis laparoscopically removed / child wish) vs. controls (endometriosis laparoscopically excluded / child wish) from the University Hospital Muenster, Germany, treated between 2009 and 2016; analysis of pregnancy rate, mode of delivery and complications using Clavien-Dindo-classification, role of deep infiltrating endometriosis using ENZIAN classification; data analysis using t-test with p < 0.050% being considered significant.

Introduction: Scientific papers on the womens's experiences of pregnancy loss aftercare in the emergency department show that how announcement is made and how much caregivers show empathy to women, help women to face this difficult moment. However, in most studies, women say they did not have enough information nor support from the medical teams. Diagnosis of miscarriage in the emergency department is the routine for the caregiver but is often experienced by the woman as the loss of a child. This study has for goal to bring to light the discrepancy between the caregivers's experience and the women's experience :the given information, the time for consultation, the empathy. Methods : 2 months after the diagnosis of miscarriage in the emergency room, patients receive a phone call with explanations about the project. If the patient gives her consent, she receives a computer questionnaire by email (questions about : reasons for coming to the emergency room, circumstances of announcement, information given in the emergency room, satisfaction with the care…) In parallel, caregivers have to complete a questionnaire about the same parameters. The main objective of this study is to evaluate womens's experiences of pregnancy loss aftercare in the emergency department of Montpellier Hospital. The second objective is to assess the discrepancy between the patient's experience and the caregivers' experience in this situation with the aim of suggesting improvement.

This study aims to determine the role of sFlt-1 and placental bloodflow evaluation in the detection of high risk for spontaneous abortion

In recurrent miscarriage, the male factor has been poorly evaluated. In fact, in the vast majority of clinical protocols of recurrent miscarriage, the sperm is not considered or assessed. Recently, some studies have suggested the presence of genetic and metabolic sperm anomalies in couples suffering from repeated miscarriages. Specifically, DNA fragmentation and altered oxidative stress in the sperm and Y microdeletions from blood samples have been related to an increased risk of miscarriage.The aim of the present study is to compare these three parameters in: couples with recurrent miscarriage; oligozoospermic men with or without recurrent miscarriages; and healthy sperm donors, in order to determine their actual impact on this reproductive problem.

This project is designed to establish whether pesticides or other environmental agents have a role in the excess birth defects identified in the Red River Valley of Minnesota. In this human study, laboratory based health parameters will be used to key in health survey data. In vitro data will be developed to mechanistic information. Concordant results among these study features will provide a weight of evidence approach.
