Filter by:Through multicenter study, the investigators aim to refine the process for precise prenatal diagnosis of fetal growth restriction (FGR), establish a cohort for severe maternal vascular malperfusion (MVM)-FGR, and conduct follow-up study to identify prognostic factors associated with both short-term and long-term outcomes.
This study aims to establish a multicenter cohort of FGR high-risk pregnant women, and aims to construct a combined predictive model for FGR by combining basic characteristics, medical history, early pregnancy ultrasound, and biomarkers.
The goal of this observational study is to develop and validate cell-free RNA-based biomarkers for predicting a variety of adverse pregnancy outcomes in a pregnant person population. The main question it aims to answer are: 1. Can cell-free RNA-based biomarkers predict which pregnant people are at greatest risk of developing adverse pregnancy outcomes (e.g., preterm birth, preeclampsia)? 2. What is the performance of such biomarkers when predicting an adverse pregnancy outcome (e.g., sensitivity, specificity, PPV, NPV, TPR)?
Objectives / Specific Aims - The purpose of this study is to investigate the acute effects of a single bout of moderate intensity maternal exercise on fetal well-being in a pregnancy affected by fetal growth restriction. Fetal well-being will be measured by biophysical profile (BPP), non-stress test (NST) and umbilical artery dopplers. - The hypothesis is that a single bout of maternal exercise will not significantly alter fetal well-being or fetal status.
This stepped wedge cluster randomized clinical trial investigates whether in pregnant women with severe, early-onset fetal growth restriction, the use of STV analysis in fetal monitoring improves the chances of perinatal survival, compared with visual evaluation of the cardiotocography.
The aim of the study is to determine, in pregnant women who have undergone sleeve gastrectomy (SG), whether ghrelin changes could be involved in in utero growth restriction (IUGR) and whether therefore a correlation between maternal ghrelin levels and birth weight is observed.
Optimal diagnostic management and underlying pathophysiological mechanisms of selective fetal growth restriction (sFGR) in monochorionic diamniotic (MCDA) twin pregnancies have not been fully clarified. The current diagnostic classification system based on three different umbilical artery flow patterns has no increasing scale of severity and the predictive value is limited. Since there is no treatment available for sFGR, predicting fetal deterioration is key in preventing single or double fetal demise. Outcome prediction is furthermore important in the selection of cases that will be offered selective reduction (to provide the larger twin with better prospects), as well as determining monitor frequency and possible hospital admission. As outcome prediction is clinically challenging, patient counselling is too, and parents often encounter a great deal of uncertainty during the pregnancy. Furthermore, little is known about the brain development of sFGR children (both during pregnancy and after birth). Moreover, the psychological impact of an sFGR pregnancy of the future parent)s) has not been studied before. The impact of these factors should be taken into account during patient counseling, which is currently not the case. By our knowledge, this is the first international, multicenter, prospective cohort study on that will address the abovementioned questions and knowledge gaps in MCDA pregnancies complicated by selective fetal growth restriction.
The purpose of this study is to compare the composite neonatal adverse outcomes (CNAO) among pregnancies complicated by fetal growth restriction (FGR) managed using the Society of Maternal-Fetal Medicine (SMFM) versus International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) antepartum ultrasound guidelines, to measure the rate of the individual components of CNAO, to record the rate of cesarean delivery during labor, to tabulate the rate of deviation from the management protocol assigned at the time of evaluation, to record neonatal intensive care unit (NICU) admission rates and to measure the rate of the composite maternal adverse outcome (CMAO).
Chronic histiocytic intervillositis (CHI) is a rare condition with an incidence of 5 in 10,000 pregnancies. This rare condition is associated with placental inflammatory lesions leading to severe and recurrent obstetrical complications: intrauterine growth retardation (IUGR), fetal death in utero and miscarriage. The pathophysiological mechanisms of CHI are poorly understood, while the empirical treatments prescribed to prevent recurrence are cumbersome and of poor efficacy. Recent findings suggest that an alloimmune response may play a role. In a recent work, the investigators have demonstrated the role of maternal alloantibodies directed against fetal HLA antigens in two patients followed for recurrent IUGR associated with CHI. Their work suggests that a humoral alloimmune response directed against fetal HLA antigens mimics an allograft rejection process. The investigators propose to extend the preliminary results obtained in these patients to provide new insights into the pathophysiological mechanisms of CHI, and eventually to predict the risks of fetal loss.
There are few safe, effective, and affordable interventions to improve pregnancy outcomes in low resource settings where the highest rates of poor birth outcomes occur. L-citrulline is naturally found in many foods and is changed into another important amino acid, L-arginine, in the body. L-arginine is important for the growth of a healthy placenta and healthy baby. Adding L-citrulline to the diets of pregnant women may be an effective and affordable way to improve the health of their babies.The goal of the AGREE trial is to test whether a dietary supplement containing a common food component, an amino acid called L-citrulline, can help pregnant Kenyan women at risk of malaria have healthier pregnancies and healthier babies. 2,960 pregnant Kenyan women will be enrolled and randomly assigned to take either a twice daily dietary supplement containing L-citrulline or a placebo supplement without additional L-citrulline. Maternal participants will be seen every month until delivery and at weeks 1 and 6 after birth. Infants will also be followed up at ages 6, 12, 18, and 24 months. The primary outcome of the study is 'adverse pregnancy outcome', a composite of foetal loss (miscarriage or still birth), preterm birth, low birth weight, small for gestational age or neonatal mortality. The results of the AGREE trial could help to guide obstetric and public health policy and provide a sustainable solution that could be implemented at the community level.
