Filter by:Recurrent miscarriage affects women of childbearing age worldwide. Vascular endothelial dysfunction and immunological impairment are associated with recurrent miscarriage To date, there is no effective or optimal therapeutic approach for these condition. Hydroxychloroquine has endothelial protective action via ant diabetic, lipid lowering, antioxidant effects or direct endothelial protection. Hydroxychloroquine is an antimalarial and immunomodulatory agent. In pregnancy, hydroxychloroquine is prescribed for inflammatory conditions associated with adverse perinatal outcomes such as systemic lupus erythematosus, antiphospholipid syndrome and placental inflammatory lesions such as chronic histiocytic intervillositis, hydroxychloroquine has therapeutic potential to improve placental function in pregnancies associated with heightened inflammation.
Earlier studies describe the half-life of hPL in serum as being ninety minutes and that the hormone is excreted unchanged in urine; consequently, there is real potential to use the fall in hormone levels in urine to monitor bleeding in pregnancy, the outcome of natural and artificial abortions or placental health. This study will focus on the fall of hPL following delivery by Caesarean section when women have a urinary catheter in place and sampling urine is simple to achieve.
This study compares the success rate of letrozole and misoprostol versus misoprostol alone for medical termination of first-trimester pregnancy among women with one or more previous cesarean deliveries.
The DEFI-1 study recruited 625 women witnesses and 299 of their spouses. With regard to case couples, 271 cases were recruited from the spontaneous repeated miscarriages (SRM) subgroup (≥3 spontaneous miscarriage (SM) from trimester 1 of pregnancy) and 93 from the unexplained fetal death in utero (FDIU) subgroup from trimesters 2 and 3 of pregnancy. The main objective of the DEFI 2 study is to increase the number of case-pairs in these 2 particular subgroups to replicate the results of the genetic determinants highlighted from cases and controls with extreme phenotypes and obtain a sufficient number of women with FDIUs to identify specific determinants.
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.
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 purpose of the study is to determine the safety and effectiveness of second trimester medical abortion when provided by nurse midwives compared with physicians. The study sample will be obtained from Michu Clinic, affiliated with St Paul's hospital, in Addis Ababa.
Pregnancy is a unique period which requires alterations in the immune system to allow for tolerance of a haploidentical fetus. The goal of this study is to measure maternal blood levels of proteins known to promote immune tolerance in early implantation and pregnancy to look for associations between tolerance, miscarriage and failed embryo transfer. Establishing predictive factors of miscarriage and failed in vitro fertilization could have implications for a large portion of couples and serve to guide current and future family planning efforts.
Although one fourth of pregnant women experience at least 1 abortion, yet only 50% of causes are identified. Pregnancy loss can result from viral, bacterial, and other infections. It can reach the fetoplacental units through blood born or local spread. Lower genital tract infections- a potentially preventable infections- was suggested as a cause of spontaneous miscarriage. It was reported in 15 and 66% of early and late miscarriages respectively. These infections are also commonly encountered among apparently healthy looking pregnant women with an overall prevalence of 40-54%. If left untreated it can lead to premature rupture of the membranes, preterm birth, low birth weight, Fetal loss, neonatal ophthalmic and pulmonary damage.
Development of mole was not associated with segregation of mutated NLRP7 allele in the haploid oocyte. We hypothesize NLRP7 is a maternal factor involved in regulating early embryo development or embryo-uterine interaction. In the proposed study, we seek to identify novel genetic variants and mutations of NLRP7 in women who experienced RM/HM. Genetic association study and haplotype analysis are performed to test assocation between NLRP7 gene and female reproductive performance. Immunohistochemical staining, RT-PCR, and Western blot analysis are used to investigate expression pattern of NLRP7 in endometrium and placenta. Two approaches are used to characterize functional significance of genetic variants/mutations. The first approach will be based on mutagenesis and the second approach will be based on induced pluripotent stem cells (iPSCs). Results obtained from the proposed study will provide novel insight into mechanism of embryo development and implantation.
