Filter by:1. Establish a multi-platform detection system for neutrophil extracellular traps in blood and tissues, and evaluate the detection performance; 2. 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; 3. 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; 4. 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.
It is a case-control study composed of 3 groups : 2 cases groups (RIF and IRPL) already composed as part of a pre-existing research project and 1 control group including patients undergoing ART for male factor infertility. The purpose of this study is to compare the 2 case group with the control group to identify metabolomics signatures.
Fetal growth restriction during pregnancy represents one of the biggest risk factors for stillbirth (Gardosi et al, 2013), with 'about one in three term, normally formed antepartum stillbirths are related to abnormalities of fetal growth' (MBRRACE, 2015). Therefore, antenatal detection of growth restricted babies is vital in order to be able to monitor and decide the appropriate delivery timing. However, antenatal detection of SGA babies has been poor, varying greatly across trusts in England in those that calculate their rates (NHS England, 2016). Most trusts do not calculate their detection rates and rates are therefore unknown. It is estimated that routine NHS care detects only 1 in 4 growth restricted babies (Smith, 2015). Oxford University Hospitals NHS Foundation Trust, in partnership with the Oxford Academic Health Science Network (AHSN) has introduced a clinical care pathway (the Oxford Growth Restriction Pathway (OxGRIP)) designed to increase the rates of detection of these at risk babies. The pathway is intended to increase the identification of babies who are at risk of stillbirth, in order to try to prevent this outcome, whilst making best usage of resources, and restricting inequitable practice and unnecessary obstetric intervention. It has been developed with reference to a body of research, however, the individual parts of care provided have not been put together in a pathway in this manner before. Therefore it is important to examine whether the pathway meets its goals of improving outcomes for babies in a 'real world' setting. The principles of the pathway are 1. A universal routine scan at 36 weeks gestation. 2. Additional growth scans at 28 and 32 weeks gestation based on a simplified assessment of risk factors and universal uterine artery Doppler at 20 weeks gestation. 3. Assessment of further parameters other than estimated fetal weight associated with adverse perinatal outcome (eg growth velocity, umbilical artery Doppler and CPR). The clinical data routinely collected as a result of the introduction of the pathway offers a valuable and unique resource in identifying and analysing in the effects of the pathway on its intended outcomes and also in investigating and analysing other maternal, fetal and neonatal complications and outcomes, establishing normal / reference ranges for ultrasound values.
Correlation between the presence of intracellular viruses/bacteria and the incidence of miscarriage during the first trimester of pregnancy.
The pre-eclampsia is a frequent pathology, concerning approximately 5 % of the pregnancies.The pre-eclampsia can evolve into severe maternal and\or foetal complications and is a major cause of mortality. The purpose of the study will to estimate the relevance of the serum markers sFlt1 and PlGF to predict the arisen of severe complications at these patients, what would allow to decrease the materno-fœtale morbi-mortality due to the pathology.
In France The prevalence of Pregnancy Loss after 12 weeks of gestation is around 3%. This situation is probably associated to a risk of post-traumatic stress disorder. As a part of the medical staff midwives are often confronted with this situation, however they can have difficulties to identify short and long term effects of a post-traumatic stress disorders. The purpose of the present study is to estimate and analyze the prevalence of short-term (1 month) post-traumatic stress disorder in women with pregnancy loss after 12 weeks of gestation.The symptoms of post-traumatic stress disorder will be tracked using the Impact of Event Scale-revisited and the Peritraumatic Dissociative Experiences Questionnaires.The diagnosis of post-traumatic stress disorder will also be clinically confirmed by a psychiatrist during a specific consultation.
The purpose of this study is to determine if patients with recurrent pregnancy loss or unexplained infertility have an altered uterine gene expression or uterine microbiome (micro-organism composition) during the window of embryo implantation. Furthermore we would like to assess for women with an abnormal uterine gene expression whether vaginal progesterone medication improves or alters gene expression and for women with an abnormal microbiome whether antibiotic treatment followed by probiotic treatment normalizes the microbiome.

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.
Intrauterine fetal death (IUFD) is defined as the occurrence of fetal death at >20 weeks' gestation. IUFD affects about 1 in 160 pregnancies (6-7 per 1000 births). Optimal diagnostic evaluation for cases of IUFD is generally based on extensive protocol testing i.e. maternal and fetal blood tests, fetal bacteriology, cytogenetic analysis, autopsy, and placental examination. This extensive protocol testing may vary in clinical practice and interpretation of the results is rarely performed by multidisciplinary staff to establish cause of death. These findings are related to the fact that there are very few epidemiological studies to validate optimal protocol, no French recommendations on this subject, and a relative lack of pathologists with expertise in perinatal pathology. Only, one recent prospective study from the Netherlands has concluded that extensive protocol testing should be redefined and some diagnostics tests may only be performed with suggestive clinical circumstances. However these recommendations may not be applicable to all populations and countries. To date, there are no French published series on IUFD to evaluate causes of death in France and thereafter to better define optimal diagnostic evaluation tests. Improvement in prenatal diagnosis in France may contribute to detection of the vast majority of severe chromosomal abnormalities and malformed fetuses and particularly those at risk of death. Retrospective cohort unpublished data on IUFD from Lille and Caen have reported exceptional deaths attributable to chromosomal or malformation abnormalities. In fact in these two series, most deaths were related to placental diseases or fetal growth retardation. The hypothesis is that extensive protocol testing is not helpful in clinical practice and selective protocol testing focused on specific risk situations can be as efficient.
