Filter by:The goal of this randomized trial is to compare two methods of induction in a fetal growth restriction population. The main question it aims to answer is: • Is trans-cervical balloon superior to prostaglandins in reducing the cesarean section rate, without increasing neonatal morbidity? Participants will have an induction of labour by cervical ripening with trans-cervical balloon in the trans-cervical balloon catheter arm and with Prostaglandins in the Misoprostol arm. Researchers will compare two methods of induction: trans-cervical balloon and prostaglandins to see if trans-cervical balloon is associated with a lower risk of cesarean delivery.
Previous studies have shown that abnormal coiling of the umbilical cord is associated with adverse perinatal outcome. For example, an umbilical cord that is non-coiled increases the chance of fetal morbidity and mortality, moreover, they have shown that the lack of the usual coiled umbilical cord configuration may result in an umbilical cord that is structurally less able to withstand external mechanical stress, on the other hand, studies from recent years show that hypercoiling - excessive coiling of the umbilical cord is associated with poor obstetric outcomes, such as fetal distress at birth, meconium staining, fetal acidosis, premature birth, intrauterine growth disorder and even fetal death. The studies carried out on the calculation of UCI include performing these measurements in two dimensions, including Doppler activation, but no studies were carried out in which three dimensions were used. The purpose of the study is to measure UCI using a 3D method in a random sample of 250 patients beyond 24 week of gestation, and to compare pregnancies with hypercoiling, hypocoiling or with a normal number of coils in terms of birth outcomes.
The purpose of this study is to determine the impact of a clinical screening strategy and genomic analysis of the factors involved in Placental Dysfunction (Preeclampsia and IUGR) in women of advanced maternal age undergoing assisted reproduction techniques (ART), specifically, in vitro fertilization (IVF) and oocyte donation.
Intrauterine growth restriction (IUGR) is defined as a velocity of fetal growth less than the normal fetus growth potential for a specific neonate as per the race and gender. These neonates face many acute problems during peripartum and after birth .The causes of IUGR may be maternal, placental, fetal or genetic and also due to combination of any of these factors. Knowledge of etiologies of fetal growth restriction (FGR) is essential, so that future care can be targeted at prevention . It is apparent that FGR is primarily caused by placental dysfunction (PIH&PE), insufficiency that lead to reduced fetal growth overall. FGR is associated with lifelong burden of chronic diseases including metabolic, respiratory, cardiovascular and neurological deficits. Pre-eclampsia (PE) is diagnosed by the combined presentation of high blood pressure and proteinuria. New definitions also include maternal organ dysfunction, such as renal, liver, neurological or haematological complications, uteroplacental dysfunction, or FGR . In an attempt to correct fetus reduced supply the placenta release various cytokines and markers as Alpha-1 anti-trypsin (AAT). The Golgi apparatus secretes this cytokine in placental cytotrophoblast and blood vessels. AAT is antinflammatory antiprotease protective molecule. AAT rises during normal pregnancy. The suboptimal rise of AAT in pregnancy are liable for increased obstetrical complications like abortion, preterm labor. AAT levels were found decreased in placenta tissues from women with PE compared that of healthy women. Although AAT deficiency is associated with several pregnancy and placental disorders, little is known regarding AAT levels and PE .
This is a multicentre, open-label, randomized controlled trial. A total of 340 singleton pregnancies with an EFW ≤10th percentile between 26+0 and 31+6 weeks will be recruited and randomly allocated to either the control or the intervention group. In the control group, standard Doppler-based management will be used. In the intervention group, different soluble fms-like tyrosine kinase to placental growth factor ratio (sFlt-1/PlGF) cutoffs will be incorporated to the current protocol to adjust the frequency of ultrasounds and to plan elective delivery.
Pregnancy pathologies can occur from implantation until childbirth. The investigators are interested in the development mechanisms of these pathologies and aim to develop therapies to treat them. The investigators need to collect samples, especially placental samples, following abortions and term and premature deliveries. Abortions will allow investigators to have non-pathological placental material up to 13 weeks. This material will serve as a reference for the understanding of the histological changes that occur in normal placentas collected at term of pregnancy. The latter will, in turn, be compared with the placentas collected during premature deliveries. Also, the abortion product will be cultivated in an environment mimicking the pathology of pre-eclampsia. This study will allow investigators to advance their understanding of the pathophysiological mechanisms of the placenta. The investigators are internationally recognized for their research on these pathologies.
Pre-eclampsia (PET) and fetal growth restriction (FGR) are common complications of pregnancy that affect up to 15% of pregnancies in the UK. These conditions can have potentially devastating consequences to mothers and babies in pregnancy. Pre-term birth, that is often medically indicated to treat severe PET and FGR can cause cerebral palsy, breathing difficulty, developmental delay and even death in affected babies. Mothers who suffer from PET are at risk of seizures, strokes, multi-organ failure and future chronic hypertension. It is now thought that PET and FGR may result from poor adaptation of the maternal cardiovascular system to normal pregnancy. This project aims to study the patterns within the maternal cardiovascular system and haemodynamic profile in women who are at high risk of PET and FGR by using non-invasive methods to gather information about the functions of their hearts and major blood vessels. The investigators hope to elucidate the patterns that may offer an early warning to mothers who may develop PET and whose fetuses may be growth restricted. This would be an opportunity to more closely monitor, modify risk factors and treat earlier women who develop these conditions. Women who are at a high risk of PET and FGR as stipulated in the relevant Royal College of Obstetrics & Gynaecology and National Institute of Clinical Excellence guidelines and who give their consent will be eligible for the study.
Aim: In this study, pesticide and pharmaceutical contaminants levels in the placenta and cord blood of pregnant women with fetal growth retardation and healthy pregnant women will be compared in placenta and cord blood samples after delivery.
In this study, microplastic levels in the placenta and cord blood of pregnant women with fetal growth retardation and healthy pregnant women will be compared in placenta and cord blood samples after delivery.
Introduction: The high incidence of intrauterine growth restriction is a public health problem; in this pathology, newborns present weight below the 10th percentile, this implies an increase in morbidity in the short term (complications due to hypoxia) and long term (pathologies typical of Fetal Programming) as well as the cost of health services. L-arginine at different doses has been used for some pathologies such as preeclampsia with controversial results. Authors have mentioned that the joint administration of l-citrulline can increase the efficacy of l-arginine. A stunted fetus is a challenge for the fetal physician; due to the complexity of the follow-up, but above all to determine the moment for the termination of the pregnancy. Finding some treatment to promote weight gain would improve the short- and long-term expectations of these infants. General objective To determine the efficacy of L-arginine + L-Citrulline (3 / 2g) every 24 hours, in fetuses with a decrease in their growth curve in the third trimester of pregnancy. Material and methods Clinical trial, parallel, controlled, randomized simple, Double blind. Two groups of pregnant women will be carried out in the third trimester; fetus with a decrease in its growth curve, percentile> 10 and <25 for gestation age, they will be given an informed consent letter and they will be randomized (double blind), they will proceed to give intervention (L-arginine + Citrin (3 / 2 g) every 24 hours Vs placebo), a follow-up will be carried out every two weeks, where the weight and growth curve will be calculated in percentile, until the resolution of the pregnancy and data will be taken from the perinatal results in both groups. Statistic analysis Medics of central tendency will be calculated and Chi squared will be applied for qualitative variables, T of student for qualitative variables and it is considered P <0.005.
