Filter by:Fetal growth restriction (FGR) is a serious complication in pregnancy that can lead to various adverse outcomes. It's classified into early-onset (before 32 weeks) and late-onset (after 32 weeks), with late-onset associated with long-term risks like hypoxemia and developmental delays. The study focuses on the role of inflammation in FGR, introducing new blood markers for better understanding and diagnosis. It also addresses the challenges of using advanced diagnostic tools in low-resource settings and explores the use of machine learning to predict FGR based on inflammatory markers, highlighting the potential of artificial intelligence in overcoming these challenges.
The study will be conducted to examine the effects of abnormal growth pattern and cerebrovascular blood flow measurements on fetal frontal lobe development with the advancing ultrasound technology. Antenatal assessment of frontal lobe development will enable clinicians to predict neurodevelopmental problems that may develop postnatally. In addition, this study will examine the effects of FGR on frontal lobe development.
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)?
The novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was discovered for the first time in December 2019 in Wuhan (China) and the disease it causes is called coronavirus disease 2019 (COVID-19). Now, this pandemic is rapidly spreading all over the world. Pregnant have higher rates of COVID-19, associated with hospitalizations, and severe in-hospital outcomes. Immune responses may have a potential role in the diagnosis, treatment, and prognosis of patients with COVID-19. So we need of identifying biomarkers for disease severity and progression.
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)
This is a study of the feasibility of a translational research clinic for pregnancies conceived by in vitro fertilisation (IVF). A group of at least 120 pregnancies (of which, at least 80 IVF-conceived) will be followed from early pregnancy to delivery, in order to gain early insights into the growth of the baby before birth, the physical and emotional adaptation of the mother to the pregnancy and how the placenta works. The investigators will collect preliminary data on how these factors may differ between pregnancies conceived with and without IVF, and between different IVF treatment modalities such as fresh or "frozen" embryo transfer IVF. The study aims to understand the practicalities of such a clinic, to identify barriers to participation in the clinic, to assess the uptake of different research measurements and to identify key measurements/time points with the greatest potential to identify and understand the origin of fetal growth and maternal adaptation differences after IVF conception in a full scale study.
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.
Type of the study: A prospective observational study Study settings: The study will be conducted at Ain Shams University Maternity Hospital, Obstetrics and Gynecology Department, Faculty of medicine over a period of six month from July 2017 to December 2017. Study population: The study population comprises 60 pregnant women at 13 to 28 week of gestation attending outpatient clinic and emergency Ain Shams University Maternity Hospital, Obstetrics and Gynecology Department, Faculty of medicine. Sample size justification Sample size was calculated using PASS 11.0 sample size calculation program and based on the study carried out by Benton, et al. (2016) Group sample sizes of 30 in group one (IUGR) and 30 in group two (Controls) achieve 80% power to detect a difference between the group proportions of 0.2910. The proportion in group one (the treatment group) is assumed to be 0.2940 under the null hypothesis and 0.5850 under the alternative hypothesis. The proportion in group two (the control group) is 0.2940. The test statistic used is the two-sided Z test with pooled variance. The significance level of the test was targeted at 0.0500. The significance level actually achieved by this design is 0.0506. The primary outcome is birth weight below the 10 the percentile. The sample size was inflated by 15.0% to account for lost to follow up (attrition problem). Inclusion criteria: Singleton pregnancy between 13-28 weeks of gestation. Pregnant women aged 18 - 35 years Pregnant women with fetal abdominal circumference (AC) < 10th percentile for gestational age (GA) on ultrasound Exclusion criteria: To exclude any factors that cause IUGR: Chronic or gestational hypertension and/or preeclampsia Premature rupture of membranes A fetus with known chromosomal and/or congenital abnormalities confirmed after delivery. Multiple gestation
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.
The main objective is to assess the role of antenatal detection of fetal growth restriction (FGR) on stillbirth, by a case-control study in a population-based sample of small for gestational age (SGA) livebirths and stillbirths in 3 French counties (Isère, Savoie and Haute-Savoie). SGA births will be defined as a birthweight below the 10th percentile of French customised birth weight curves. Our secondary objectives are - to identify determinants of antenatal detection of FGR among a representative sample of SGA births, with a special interest in the definition of FGR. Our hypothesis is that births who are SGA by customised birthweight curves and non-SGA by population birthweight curves, are not detected antenatally, despite the current strategy including the use of umbilical Doppler. - to analyse prenatal care of a subsample of SGA stillbirths with and without detection of FGR by a confidential enquiry.
