View clinical trials related to Intrauterine Growth Restriction.
Filter by:The purpose of this prospective cohort study is to build a large platform that includes clinical information (prenatal diagnosis and postnatal follow-up data) and biological specimen banks of fetuses/infants with IUGR or congenital anomalies, which provide vital support and research foundation for accurate diagnosis, precision treatment and meticulous management.
The study hypothesis is that intrauterine growth restriction (IUGR) may have long-term effects on respiratory muscle (RM) function, thus leading to reduced exercise capacity later in life. The objective is to investigate the above hypothesis by comparing RM function and cardiopulmonary exercise testing (CPET) parameters between school-aged children exposed to IUGR and healthy controls.
Pregnancy is considered a cardiovascular (CV) stress test, and complicated pregnancies are associated with an increased risk for cardiovascular disease (CVD) later in life. Moreover, it is known that often the pregnancy induced CV adaptation does not resolve completely after a short postpartum (PP) period and it is not clear whether these induced changes will resolve over a longer period of time (i.e. in the upcoming months/years after delivery). Understanding the cardiac adaptation during pregnancy and the reversal process in the postpartum period, as well as the factors that influence this these processes, may provide us not only insight in this mechanism, but may help us in identifying factors that may be target points for modification.
Purpose: Clinical assessment (anthropometric) and paraclinical (biochemical and immunological by dosing serum insuline growth factors IGF1 and IGF2 and their receptors) of neonates with intrauterine growth restriction (IUGR) and the integration in a multidimensional statistical model . Objectives: 1. IGF1 and IGF2 evaluation of serum and IGF1 receptor, IGF2 receptor and IGF2 receptor gene expression in cord blood from newborns with intrauterine growth restriction (IUGR). (Prospective) 2. Evaluation and monitoring of anthropometric, clinical (non-cardiac morbidity) and paraclinical. (Retrospective & prospective) 3. Evaluation and monitoring of morphological and functional by echocardiography. (Prospective) 4. Integrating multidimensional clinical and paraclinical parameters in a statistical model for evaluating newborn with intrauterine growth restriction.
The aim of this prospective longitudinal study was to investigate the relationship between placental thickness during the second and third trimesters and placental and birth weights.
The ultimate goal of this project is to develop methods that allow informed decision-making on the delivery time of fetuses that are at increased risk of stillbirth due to IUGR. In placenta related IUGR pregnancies, there can be multiple concurrent placental pathologies. Although there is no specific correspondence between a single type of pathology and IUGR, the common result of these pathologies is placental insufficiency, which limits the maternal-fetal exchange. Oxygen and nutrition transport is known to be hindered in IUGR placentas due to obstructed or abrupt vasculature, massive fibrin deposition, and inflammation in the villous and intervillous space (villitis). Thus one potential approach to distinguish IUGR pregnancies from normal ones is to assess the efficiency of placental transport. Based on the hypothesis that efficiency of oxygen transport is representative for overall oxygen and nutrition transport in placenta, the investigators propose to characterize the blood oxygenation and blood perfusion in placenta in vivo via MRI, and use it as an index for better stratification in the IUGR risk group. The investigators will also consider alternative MRI approaches such as structural, diffusion and spectroscopy measurements inside the placenta, which might reflect the state of placental transport and reveal the status of placental health. Specific aims: 1) To correlate the MRI metrics that differentiate placental insufficiency from normal placenta transport with histopathology data of the placenta. 2) To correlate the MRI metrics that reflects placental insufficiency with fetal outcome
