Filter by: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.
This is an interventional multi-centre study comparing two groups of general practitioners with or without an ultrasound scanner over a period of 6 months. The evaluation focuses on the management of patients for 8 pathologies: - Pneumonia - Pleural effusion - Renal colic - Hepatic colic or cholecystitis - Subcutaneous abscess or cyst - Fracture of long bones - Intra-uterine pregnancy or extra-uterine pregnancy or miscarriage - Phlebitis The principal hypothesis is that there are fewer complementary exams in the group of doctors using ultrasound scanners. The secondary hypotheses are: - There is better patient orientation (emergency care, specialist consultation, return home) in the group of doctors using the ultrasound scanners. - The global cost of the care is lower in the group of doctors using the ultrasound. - Using ultrasound during the consultation decreases the anxiety of the patient. - Using ultrasound increases the duration of the consultation. - There is no difference between the predicted and the real orientation of the patients.
The present study is based on the hypothesis, that recurrent pregnancy loss (RPL) is associated with abnormal plasma mannose binding lectin (p-MBL) level. Secondarily, p-MBL level may affect the reproductive and the perinatal outcome in the first pregnancy following RPL. Thus, the present study aim to examine whether MBL should be a biomarker for women at risk for RPL and, secondarily, affect the reproductive and perinatal outcome, and thereby help clinicians identify fragile women who need intensified perinatal care.
The purpose of this study is to demonstrate the ability of low dose IL-2 to stimulate peripheral blood Tregs of women with unexplained repeated early spontaneous miscarriages for development of a therapy to prevent fetal rejection by low dose IL-2.
This is a prospective observational study. Eligible women undergo ART treatment in our centre will be recruited for the study and each woman will only be included in the study once. Informed written consent will be obtained. Blood serum for hCG level is performed 14 days after the embryo transfer i.e. week 4. If the serum hCG level is >10IU/L, the women are considered pregnant and blood will be saved and checked for kisspeptin level, Another blood test is repeated 1 week later i.e. week 5. A transvaginal ultrasound and blood test will be performed 1 week later i.e. week 6 to confirm the fetal viability and the number of gestational sacs and locate the pregnancy. Blood for hCG and kisspeptin levels are checked at weeks, 4, 5 and 6. Ultrasound will be performed at gestational 8 weeks and 11 weeks. They will be referred for antenatal care when the pregnancy is confirmed on-going at 11 weeks. The purpose is to determine whether serum kisspeptin level in women who conceive in IVF is associated with an increased risk in first trimester miscarriage and compare with serum hCG level in the prediction of the first trimester miscarriage.
Recurrent unexplained spontaneous miscarriage (RSM) is defined as three consecutive pregnancy loss prior to 20 weeks from the last menstrual period. 1% to 2% of women experience RSM. Treatment of URSM is a challenging issue. The currently available lines of treatment according to simplicity of use, reliability and degree of invasiveness include corticosteroids, sildenafil citrate, aspirin, heparin and immunoglobulins (besides good antenatal care), but up to now there are no prospective randomized studies, powerful enough, to determine a significant difference between these therapeutic protocols, with any of the above mentioned pharmacological agents. Sildenafil Citrate (Viagra®), a vasodilator, is also described as an anti-inflammatory agent. While improving uterine blood flow in the proliferative phase, NO may have detrimental effects at the level of the endometrium during the implantation window. The NO- mediated release of cytokines such as tumour necrosis factor- from activated natural killer cells has been implicated as a cause of implantation failure. Based on these observations, this study attempts was made to study uterine arteries and sub-endometrial blood flow during the luteal phase in normal fertile women and in patients with Unexplained recurrent miscarriage
The goal of the study is to determine whether important clinical outcomes differ among women who access a combined medical abortion regimen from a pharmacy when compared with those who access it from a facility.
Platelet indices might be a marker for platelet activation, and thus could predict thrombosis. This might be the cause in some cases of recurrent miscarriage. This study aims to evaluate the use of platelet indices -as a simple test- to predict recurrent miscarriage.
Miscarriage affects one in five pregnancies and little progress has been made in understanding and treating this distressing condition. C. trachomatis is the most common sexually transmitted infection in the UK. C. trachomatis infection can have serious health consequences, including fallopian tube damage. Untreated C. trachomatis infection and tubal damage have been associated with miscarriage and adverse pregnancy outcomes such as preterm birth, low birth weight and stillbirth. A cohort study is needed to establish the prevalence of tubal disease in women with recurrent miscarriages. HyCoSy will be performed to identify tubal disease and establish the magnitude of the problem in the recurrent miscarriage population. The prognosis of tubal disease on miscarriage and other obstetric outcomes, and the role of medical interventions such as tubal surgery (to treat hydrosalpinx) on reducing miscarriage and adverse obstetric outcomes will also be studied. Objectives 1. Establish the prevalence of hydrosalpinx in the recurrent miscarriage population. 2. Establish the prognosis of women diagnosed with recurrent miscarriage with concurrent hydrosalpinx. 3. Explore the role of tubal surgery for improving reproductive outcomes in women with recurrent miscarriage population and hydrosalpinx.
