Background Miscarriage is the most frequent complication of pregnancy and represents the spontaneous loss of the embryo or foetus before it is able to survive independently (24 weeks of gestation). It affects up to 50% of pregnancies with the vast majority (80%) occurring at pre-clinical stage before the woman recognises the pregnancy. Up to 5% of couples suffer recurrent miscarriage defined as 2-3 or more miscarriages leading to physical, emotional and financial consequences for couples, doctors and medical systems. Different maternal health problems (thyroid disease, sticky blood, autoimmune disease, anatomical anomalies of the womb) and embryo defects may be responsible for some of the miscarriages; however, more than 50% of the occurrences have no identifiable cause based on the current diagnostic tests. Aim The aim of the present research proposal is to understand the role of the lining of the womb in miscarriage and to explore the development of a potential implantation test that is cost-effective and may be implemented in clinical practice. Methods Over a period of two years, women who suffered recurrent miscarriage will be approached in the advanced miscarriage clinic at Birmingham Women's Hospital during their routine appointment. Participants will be invited to participate by undergoing chromohysteroscopy and/or a biopsy from the lining of the womb during an outpatient appointment. Chromohysteroscopy is based on a routine hysteroscopy which involves visualising the inside of the womb using a narrow telescope passed through the neck of the womb (cervix). "Chromo" comes from the fact that an iodine based dye will be injected to increase the power of the test. The biopsy will be taken using a narrow plastic tube passed through the cervix. It is a standard diagnostic test for women with abnormal bleeding. As part of the present research, different cells and molecules will be analysed from the biopsy sample.
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 study group included 910 women who attended Fayoum university hospital gynecology outpatient clinic for postabortive evaluation. The control group included 940 women attended outpatient clinic for any other procedure or complaint
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 development and improvement in Preimplantation genetic diagnosis/screening (PGS) in association with the efficacy and security of vitrification and trophectoderm biopsy, more efficient stimulation schemes and laboratory improvements in culture and embryo selection have contributed to high success of the assisted reproductive technologies(ART). Transferring an euploid embryo avoids one of the main reasons of miscarriage and implantation failure ( Rubio et al, 22016) and overcomes one of the most important confounding factors. Usually, the transfer of euploid embryos is performed under standard hormone replacement therapy (HRT) and are referred to as FET-PGS cycles( Frozen embryo transfer). The study of FET-PGS cycles with the transfer of a single euploid blastocyst is the best model for evaluation of the impact of the endometrial preparation . Among factors influencing FET outcomes, patient's age, endometrial preparation, endometrium thickness, endometrial pattern, number and quality of embryos transferred , difficulty at ET, recently P4 have received more attention . The importance of Progesterone (P4) in embryo implantation has been widely studied. P4 plays an important role in endometrial gland formation, embryonic implantation and pregnancy maintenance, both in natural and artificial cycles.
Non-medical used of misoprostol for abortion is a growing concern in Guadeloupe. Such situation is reasonable for countries in which abortion is not easy to obtain or prohibited. However regarding the risk of complications, it is less understandable in region like Guadeloupe where legal abortion with medical assistance is accessible for all and free. The aim of the study is to investigate on the amount of misoprostol taken by women in Guadeloupe, by doing an analytical measurement. The aim is to evaluate batter this practice in Guadeloupe, when the main objective of the study is to detect the presence or the absence of misoprostol in the urine sample of the woman coming at hospital for threatened miscarriage or miscarriage complications. Moreover, these abortions can be more important than spontaneous miscarriage.
The aim of this study is to compare the rate of miscarriage at first spontaneous pregnancy among women with endometriosis with the rate of miscarriage at first spontaneous pregnancy among women without endometriosis.
Recurrent pregnancy loss (RPL) is a clinical problem affecting 1-5% of couples of reproductive age. The contribution of thrombophilia to RPL is disputed. This controversy is partly due to low sensitivity of the genetic variants currently used to evaluate hereditary thrombophilia: the Leiden mutation (identified as rs6025) in the coagulation factor 5 (F5L) gene and mutation G20210A (identified as rs1799963) in the prothrombin (PT) gene. Our objective was to determine whether a wider algorithm that includes clinic and genetic variants associated with thrombophilia could be more useful in the prediction for RPL than FVL and PT alone.
The aim of the study was to define the possible association between heavy iron level and the consequence of pregnancy especially spontaneous abortion and missed abortion. The study population will comprised the first-trimester pregnant women in the PUMCH (Peking Union Medicine College Hospital) during 2017 October to 2018 November. We categorised the patients into two groups, the study group where the patients suffered from spontaneous abortion or missed abortion, and the control group where the patients carry the normal live fetal for at least 8 weeks and ask for artificial abortion. All the cases included in the study were examined with respect to 6 kinds of heavy iron level in venous blood and urine, then correlation analysis was applied to define heavy iron level between two groups.
