Active clinical trials for "Pregnancy Complications"

The occurrence of a spontaneous fetal loss (FL) is a rather frequent event: it has been estimated that up to 15% of pregnancies result in a fetal loss. However, recurrent events, defined as >2 or >3 loss, depending on the guidelines used (American College of Obstetricians and Gynecologists or Royal College of Obstetricians Gynaecologists guidelines), occur in 1 % of all pregnancies and it is noteworthy that Recurrent Fetal Loss ( RFL) in about 30-40% of cases remain unexplained after standard gynaecological, hormonal and karyotype investigations. Furthermore, it is important to consider that chromosomal abnormalities are responsible for at least 60% of FL in the first trimester, thus an abnormal karyotype in the fetus should be excluded prior to consider testing women for genetic susceptibility to placental vascular complications (inherited thrombophilia). Common inherited conditions, the factor V Leiden (FV) and the factor II G20210A (FII) mutations have been recognized as risk factors for FL. The efficacy of treatment with antithrombotic drugs during pregnancy in women with a history of RFL/ Intra Uterine Fetal Death (IUFD) and thrombophilia is still debated, due to scarcity of available data. Italian guidelines suggest the use of Low-Molecular-Weight Heparin (LMWH) in women with FV or FII mutations and previous otherwise unexplained obstetric complications, while guidelines released by RCOG suggest that heparin therapy during pregnancy may improve the live birth rate in women with second trimester loss associated with inherited thrombophilias. Hence, the idea to propose this prospective observational study comparing clinical data and outcomes in women with common inherited thrombophilias and in women without. During this study the investigators will collect and evaluate clinical data from examinations and visits by patients, eligible for the study as carriers of thrombophilic defects. This observation will begin before pregnancy and continue until the puerperium, allowing us to study all possible factors influencing these conditions. The study will add knowledge for improving feto-maternal prognosis and preventing spontaneous and recurrent FL. Plan of the study: multicenter observational study

The investigators aim to perform a qualitative study to explore the views of women with a breech presentation on their management in general, and the use of anaesthesia or analgesia for ECV in particular.

The bile acids has been demonstrated to cause arrhythmia and abnormal calcium dynamics in cultured neonatal rat cardiomyocytes. Bile acids may alter maternal cardiomyocyte function like fetus.Increased P-wave duration and P-wave dispersion have been reported in various clinical settings. The investigators hypothesized that PWD and p wave duration may affect in pregnancy with ICP.

The purpose of this study is to characterize the incidence and clinical features of the maternal COVID 19 infection, as well as the associated morbidity of the mother and the child, in the French context

Adenomyosis can be defined as the settling of endometrial gland cells in the myometrium and deformity in the uterus and the prevalence of adenomyosis is according to the patient population and countries around 20%. There are recent publications reporting that this rate increases up to 50% in women dealing with infertility. In adenomyosis, where uterine morphology is affected, it is not thought that the uterus, which is expected to provide many morphological adaptations during pregnancy, will not be affected. Therefore, in this prospective study, it was planned to investigate the effects of adenomyosis during pregnancy. For this study the presence of adenomyosis will be questioned by using ultrasonographic morphological uterine limitation (MUSA) in women who apply to the outpatient clinic with suspicion of pregnancy and undergo transvaginal ultrasonography for the diagnosis of pregnancy before sixth gestational week. Patients will be divided into two groups according to the presence of adenomyosis and pregnancy complications such as preterm labor, premature rupture of membranes, cesarean section rates, preeclampsia, fetal malpresentation and preeclampsia will be compared between the groups.

Study title Spanish Registry of Pregnant Women with COVID-19 Protocol number and version Number 55/20. Version V8. Sponsors This registry is a project promoted by Dr. Oscar Martínez Pérez of the Obstetrics and Gynaecology department of the Puerta de Hierro University Hospital. Principal investigator of the registry National coordinator: Dr. Óscar Martínez Pérez. Obstetrics and Gynaecology Department. Puerta de Hierro University Hospital. Majadahonda. Epidemiologist: Maria Luisa de la Cruz Conti Researchers for each site: 100 sites from 32 Spanish provinces are included (Appendix 1) Funding Neither the hospitals nor the participating investigators will receive any financial compensation for their collaboration. A bank account has been opened at the hospital's Biomedical Research Foundation to receive donations: COV20/00021 - SARS-COV-2 and the COVID-19 disease Call financed by the Carlos III Institute of Health and co-financed with ERDF funds. Abstract Rationale: Knowledge about the impact of the SARS-CoV-2 virus on pregnancy is still scarce and all current recommendations are based on less than 100 cases published in the literature. To identify moderate effects (such as vertical transmission, obstetric morbidity, foetal death, maternal or neonatal death) and to allow accurate risk estimates, larger sample sizes than those currently available are required. Methods: Prospective observational study of pregnant women in whom SARS-CoV-2 infection is suspected at any time during pregnancy with positive test results for SARS-CoV-2, in order to create a registry of baseline characteristics of the pregnant woman, aspects related to the course of pregnancy and delivery, and related to the new-born, with an observation period of up to 14 days after delivery. Subsequently, several phased studies will be conducted to help establish and monitor the set of measures to improve the care of pregnant women. Discussion: The national registry for COVID-19 in pregnancy described here is a tool for sharing and centralizing data related to exposures to SARS-CoV-2 during pregnancy in a structured way. It should speed up the process of prospectively obtaining a large unbiased data set and will collect information at national level.

Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder of pregnancy that typically presents in late pregnancy with generalised itching. ICP is associated with an increased risk of pregnancy complications, including premature labour, fetal distress, and stillbirth. Models of the fetal heart (using cells from rodents) have shown that high bile acids levels cause an abnormal heart rhythm (arrhythmia), which may be the cause of stillbirth. High levels of bile acids also cause preterm labour in animal models. This pilot study aims to assess whether severe ICP, defined as maternal serum bile acid levels ≥40μmol/L, is associated with abnormal fetal heart rhythms and abnormal myometrial contractility, which may lead to preterm birth. Fetal heart rhythms and myometrial contractility will be recorded using a portable electrocardiogram (ECG) device, the Monica AN24. This monitors the fetal heart and myometrial activity via stickers applied to the mother's abdomen. It also records the maternal ECG. It will also study women with uncomplicated pregnancy, in order to make comparisons. The importance of maternal position during sleep has also more recently been established, with some studies demonstrating an association between the risk of stillbirth and the position the mother was sleeping in. Work by Stone et al published this year has shown that the maternal sleep position has a significant impact on the fetal sleep state and fetal heart rate, (in particular something called the fetal RMSSD value). The researchers therefore wish to identify any potential correlation between fetal heart arrhythmia and maternal sleep position. To do this they will use a Zephyr BioPatchTM which provides a clear indication of whether the patient was in left lateral, right lateral or supine position.

Congenital and acquired thrombophilia were identified as risk factors for thrombosis in systemic vessels.Thrombophilias have also been recently found to be associated with preeclampsia, intrauterine fetal growth restriction (IUGR), placental abruption, intrauterine fetal death (IUFD) and repeated pregnancy loss.These severe pregnancy complications are thought to result from thrombotic events occurring in the uteroplacental circulation. Accumulating data have established an association between elevated plasma activity of factor VIII and thrombosis although the mechanism is still not defined and elevated factor VIII activity is now regarded as being equivalent to thrombophilia. We intend to investigatthe association between factor VIII levels and severe pregnancy complications which are considered to result from placental vascular pathology, i.e., preeclampsia, IUGR, placental abruption and IUFD. We hypothezise that the prevalence of elevated factor 8 will be higher among women with pregnancy complications compared to controls.

This is a multicenter, non-comparative, observational study that will recruit women with singleton pregnancy and chronic HCV infection to determine the natural history of chronic HCV in pregnancy and the rate of vertical transmission to their infants. All participants will be offered curative therapy with sofosbuvir/velpatasvir (Epclusa ®) after delivery and the cessation of breastfeeding. Subjects may be enrolled at any time after conception up through 36 weeks gestation. The management of subjects in pregnancy will be in accordance with ACOG guidelines and individual clinical judgment, however testing will include, but not be limited to, testing for HCV infection, HIV infection, HBV infection, HSV infection, group B Streptococcal colonization, HCV genotype, HCV viral load, as well as assessment of hepatic and renal function. Subjects will be followed on a schedule that is determined by their obstetric care providers throughout their pregnancy. Following delivery, infants will be evaluated at 12, 24 and 48 weeks of age, with testing for HCV RNA to be obtained at each evaluation. Vertical transmission is defined as two positive HCV RNA PCR tests, at least one before the 48 week infant visit, and again at the 12-month follow-up infant visit.

This is a population-based study to obtain data for the evaluation of current used recommendations for weight gain during pregnancy released by IOM (2007) and investigate the association between maternal diet and the health outcomes of mother and offspring.
