Filter by:The overall goal of this large, pragmatic, comparative effectiveness trial is to test the hypothesis that among at-risk individuals, 162 mg/day aspirin is superior to 81 mg/day in preventing Hypertensive disorders of pregnancy (HDP), and that there are multiple factors associated with adherence with aspirin therapy that will be important to identify to enable optimal implementation of study findings and population-level benefits.
Preeclampsia is a hypertensive disorder of pregnancy associated with important maternal and perinatal mortality. It complicates 2 to 5% of pregnancies and causes more than 70 000 maternal deaths each year worldwide. Although symptomatic management has improved there is currently no curative treatment, and only childbirth and delivery of the placenta, usually prematurely, alleviate the mother's symptoms. The management of extremely preterm infants is a major societal challenge in medical, ethical and economic terms. Placental insufficiency plays a central role in the pathophysiology of preeclampsia. Abnormal placentation during the first trimester leads to placental hypoperfusion, which induces trophoblast dysfunction and the release in maternal circulation of trophoblastic factors leading to the maternal symptoms. Among molecules that participate to the pathophysiology of preeclampsia, one of the most important players is soluble fms-like tyrosine kinase 1 (sFlt-1), which is a soluble form of the vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF) receptor. sFlt-1 binds to free VEGF and PlGF in the maternal circulation, thus reducing their bioavailability for their membrane receptors. Targeting the sFlt-1 pathway is one of the most promising strategies for the development of new treatments for preeclampsia. As sFlt-1 results from alternative splicing, its peptide sequence is identical to that of the extracellular part of the membrane receptor. The development of drugs that act specifically on the soluble form and not on the membrane form is therefore particularly complex. The general objective of this research is to restore the angiogenic balance that maintains the physiological concentrations of free angiogenic factors in order to significantly prolong the pregnancy and diminish the consequences of the great prematurity. The precise objectives of the APHERESE 2 project are: 1. To transpose the proof of concept of the APHERESE1 project to the scale of a real apheresis column 2. To develop an innovative assay technology to determine the global circulating angiogenic balance for each patient
Preeclampsia (PE) is a leading cause of maternal-fetal morbidity and mortality, affecting 3-8% of pregnancies and causing over 76,000 maternal deaths annually. PE is characterized by high blood pressure and proteinuria or organ damage/intrauterine growth restriction (IUGR). There are two phenotypes: placental PE, caused by abnormal trophoblast invasion, often leading to early pregnancy complications and IUGR, and metabolic PE, associated with maternal metabolic issues like visceral obesity and metabolic syndrome, leading to low-grade inflammation and insulin resistance. Recent research highlights the role of maternal gut microbiota in these conditions, suggesting that gut dysbiosis-altered microbial balance-can influence systemic immune responses and contribute to PE. This study aims to characterize the maternal gut microbiota in the two PE phenotypes to better understand their distinct etiologies and improve prediction and prevention strategies.
Preeclampsia (PE) is a significant cause of maternal and fetal morbidity and mortality, characterized by high blood pressure and proteinuria during pregnancy. It has two main phenotypes: one linked to placental damage and the other to metabolic factors like obesity. Early identification of high-risk groups is crucial, though there's ongoing disagreement over its classification. Research suggests a potential connection between maternal gut bacteria and PE, offering avenues for improved prevention strategies. This study aims to investigate the differences in maternal gut microbiota between these two PE phenotypes.
Investigation of the relationship between maternal serum vasohibin-1, vasohibin-2, cardiotrophin -1 and endocan concentrations at the 11th and 14th weeks of gestation and adverse perinatal outcomes.
The goal of this clinical trial is to evaluate stress and cardiovascular risk factors in women with preeclampsia in the medical history. The main questions it aims to answer are: - to improve our understanding of the underlying psychological and physical stress factors in relation to the circulatory risk profile in women with a history of preeclampsia - to examine the effects of mindfullness based stress reduction (MBSR) or aerobic exercise training on hair cortisol and symptoms of mental stress. Participants will undergo pre- and post-intervention pre-conceptional standard cardiovascular assessments, head tilt test and give a hair sample. As intervention they will sport or do mindfulness for 3 months.They will be compared with a control group.
Preeclampsia is a major devastating disorder affects 2:10% of pregnancies worldwide. preeclampsia may be associated with placental insufficiency which may cause fetal blood redistribution to essential organs like brain, heart, kidney.
This is Observational study, aiming to investigate the potentiality of cffDNA and cfRNA by a non-invasive test, in combination with clinical characteristics, to establish models for early screening and predicting high-risk pregnancy of PE, SPB, and GDM in Vietnam.
Preeclampsia is the main cause of illness and death in pregnant women and fetuses. Currently, there is no effective treatment for preeclampsia in clinical practice, and the fundamental treatment is still termination of pregnancy and placental delivery. Therefore, early prediction of preeclampsia and targeted strengthening of high-risk pregnant women supervision, early intervention and diagnosis and treatment can greatly reduce the serious obstetric complications and perinatal maternal and fetal deaths caused by preeclampsia, which has significant social and clinical significance.
The purpose of The Preeclampsia Registry is to collect and store medical and other information from women who have been medically diagnosed with preeclampsia or a related hypertensive (high blood pressure) disorder of pregnancy such as eclampsia or HELLP syndrome, their family members, and women who have not had preeclampsia to serve as controls. Information from participants will be used for medical research to try to understand why preeclampsia occurs, how to predict it better, and to develop experimental clinical trials of new treatments. The Registry will consist of a web-based survey and mechanism for collecting and reviewing medical records. This data will be utilized for immediate investigator-driven cross-sectional research projects (after proposal review by the Registry's scientific advisory board and as directed by the PI). Participants may also choose to be contacted regarding possible participation in future studies, about providing a biospecimen, as well as investigator-driven clinical trials. The Registry is anticipated to exist long-term and to serve as a foundation of participants from which to draw for studies of preeclampsia, anticipated to evolve as our scientific understanding of preeclampsia evolves.
