Filter by: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.
This study, to be carried out immediately following an emergency, reactive cholera vaccination campaign in Nsanje District, Malawi, will be a cohort study to estimate the safety of killed oral cholera vaccine (OCV), in pregnant women as measured by ShancholTM, on pregnancy outcomes and birth defects. While limited evidence which suggests that the vaccine is safe in pregnant women, this setting will allow investigators to answer this question in a community where more than 100,000 people will receive vaccine with no restrictions on pregnancy status. In past cholera vaccine campaigns including clinical trials, pregnant women were excluded due to lack of safety data. However, in this campaign, the decision by the Ministry of Health is that the benefits of offering vaccine to all individuals regardless of pregnancy status far outweigh any theoretical risk. Here the investigators specifically propose to: Specific Objective 1: To conduct surveillance of pregnant women to detect adverse pregnancy outcomes within communities in Nsanje District, Malawi that received oral cholera vaccine in a reactive vaccination campaign that started on 30 March 2015. Through household surveying and enrollment of pregnant women with monthly follow-up visits, the investigators will determine the cumulative incidence of adverse pregnancy outcomes among vaccinated and unvaccinated women in Nsanje and Chikwawa Districts, Malawi. Specific Objective 2: To compare the cumulative incidence of pregnancy loss (miscarriage and stillbirth) of women who received oral cholera vaccine while they were pregnant to women who were vaccinated and became pregnant after the end of the final round of vaccination in Nsanje and Chikwawa Districts, Malawi. Specific Objective 3: To compare the incidence of newborn malformations in a cohort of infants that had fetal exposure to oral cholera vaccine compared to those without such exposure in Nsanje and Chikwawa Districts, Malawi.
The Vitamin D and Angiogenic Marker Study 1: Vitamin D and angiogenic markers in early pregnancy. Epidemiology and associations to early-pregnancy miscarriage
Value of pelvi- abdominal ultrasound and Doppler in diagnosis of retained products of conception after second trimester miscarriage to select who will benefit from surgical evacuations or conservative management.
To compare the success rate of letrozole and misoprostol versus misoprostol alone for medical termination of pregnancy in second trimester abortion.
The China-Anhui Birth Cohort Study (C-ABCS) was set up to examine the delayed, cumulative and interactive effects of maternal environmental exposures on birth outcomes and children's development. The C-ABCS recruited pregnant women from six major cities of Anhui province, China, between November 2008 and October 2010. A range of data (including demographic, obstetric, occupational, nutritional and psychosocial factors) were collected by both interviews and laboratory tests. In each trimester, women's blood samples were drawn, and pregnancy complications were abstracted from physician's medical records. By the end of 2011, birth outcomes/birth defects were observed/identified by clinicians within 12 months after the delivery of 11 421 singleton live births of six cities and those outcomes among the remaining 2033 live births are still being observed. In addition, 4668 children from Ma'anshan city will be further followed up during the pre-school period till they reach adolescence to obtain the data on familial environmental exposures as well as children's physical, psychological, behavioural and sexual development. The interview data and information on laboratory examinations are available on request from archives in the Anhui Provincial Key Laboratory of Population Health & Aristogenics.
Recurrent pregnancy loss (RPL) affects 5% of couples trying to achieve parenthood. Most cases of RPL are unexplained and have no effective treatment to improve the likelihood of a pregnancy resulting in a live birth. This leads to significant patient and provider frustration and emotional stress. Hydroxychloroquine (HCQ) is a medication commonly used in pregnancy to treat autoimmune and connective tissue diseases such as systemic lupus erythematosus (SLE). This use has shown that HCQ is very safe in pregnancy. HCQ has anti-inflammatory and anti-thrombotic effects and thus may improve pregnancy outcomes in couples with unexplained RPL. Although some providers are already prescribing HCQ for unexplained RPL, a randomized controlled trial is necessary to determine the true efficacy and safety of this treatment. This study has the potential to establish support for a new treatment option for unexplained RPL.
The main objective of this study is to describe the level of expression of the biological factors involved in the formation of adhesions (Transforming growth factor beta, Activin A, inhibin) at the time of a first diagnostic hysteroscopy among women with synechia, another intracavitary disease or no intracavitary disease.
Evaluation of the effect of altering the timing of initiation of low molecular weight heparin (LMWH) administration on the pregnancy outcomes in women with antiphospholipid syndrome (APS)
EmbryoGen and BlastGen contain the cytokine growth factor Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF), which has been documented to give significant benefit to this difficult group of patients. Results showed a highly significant effect of 44% relative improvement in ongoing implantation rate (p=0.001) in women who have previously miscarried (Ziebe et al 2013). We wish to undertake a randomised Controlled trial to determine if EmbryoGen/BlastGen media improves pregnancy outcomes in women with recurrent implantation failure, recurrent miscarriage and poor embryo development when compared to standard media.
