Filter by: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)?
Due to the fetoneonatal pathway it is possible to identify pregnant women with an increased risk of fetal growth restriction or pre-eclampsia in early stages (from 10th week of pregnancy). Women whose pregnancy is considered high-risk receives risk-adapted prenatal treatment as well as certain treatments for their newborn and infant until 1 year of age. The tasks of all involved persons are defined by standard operating procedures (SOP)
Approximately 10% of all pregnancies experience mal perfusion of the placenta resulting in fetal growth restriction (FGR) of the fetus. FGR is the most important cause of perinatal mortality and morbidity. Impaired placental function determined by insufficient transformation of the uterine arteries and mal-perfusion of the placenta is the leading cause of FGR. So far, there is no treatment option for pregnancies complicated by FGR and the clinical management is restricted to close monitoring, assessing for the optimal time point of delivery of the fetus threatened by intrauterine death. In a pilot study a risk reduction of 38% for the development of severe FGR and FGR or death could be demonstrated by giving the organic nitrate pentaerithrityl-tetranitrate (PETN) to patients recognized at risk for FGR by impaired uterine artery Doppler at mid gestation (Schleussner, 2014). To confirm these results this prospective randomized placebo controlled double-blinded multicentre trial, was initiated.
The aim is to increase awareness of the relationship between (IUGR) and cardiac function in the foetus, the development of cardiac function over time after delivery and what significance a possible early disturbed myocardial function have for the neonate and the child during the first years of life.
Objective: The impact of intrauterine growth restriction (IUGR) on perinatal morbidity and long-term neurodevelopmental outcome has been published in numerous studies. Throughout this analysis, the influence of IUGR on the postnatal amplitude-integrated EEG (aEEG) in preterm infants below 30 weeks of gestation was assessed. The second concern was the correlation between the pattern of the aEEG in the first two weeks with neurodevelopmental outcome, comparing infants with and without IUGR. Methods: Routinely assessed aEEG data of preterm infants with IUGR born below 30 weeks of gestation in the years 2005 until 2007 were analysed retrospectively according to the aEEG score (combining occurrence of sleep-wake-cycles, background activity and suspected seizure activity). Neurodevelopmental outcome was evaluated at 24 months using the Bayley Scales of Infant Development and standardized neurologic examination.
Objective: To investigate the role of maternal serum YKL-40 and uterine artery doppler, at gestational age 12, 20, 25 and 32 weeks, and the relation to preeclampsia and intrauterine growth restriction. The serum marker YKL-40 is related to conditions involving inflammation, infection, tissue remodeling, fibrosis and cancer. IUGR and preeclampsia are known to be related to inflammation and tissue remodeling. Methods: women attending screening for downs syndrome is scanned with uterine artery doppler and delivered blood samples at GA 12, 20, 25 and 32 respectively. When pregnancy outcome is registered by medical records blood samples are retrieved and analyzed for serum YKL-40. Serum YKL-40 are correlated to the presence of bilateral notching, preeclampsia and different degrees of intrauterine growth restriction.
