Filter by:Women who develop preeclampsia during pregnancy are more likely to develop cardiovascular disease later in life, even if they are otherwise healthy. The reason why this occurs is unclear but may be related to blood vessel damage and increased inflammation that occurs during the preeclamptic pregnancy and persists postpartum. The purpose of this investigation is to 1) determine the mechanisms contributing to this lasting blood vessel damage and chronic inflammation, and to 2) identify factors (both physiological and pharmacological) that mitigate these negative effects in order to inform better clinical management of cardiovascular disease risk in women who have had preeclampsia.
This study will investigate the interplay of different immune cells and placental cells as well as their potential for the development of pregnancy complications. In particular, the translation of the uteroplacental syndrome into a maternal syndrome, considered in the multifactorial pregnancy disorder preeclampsia, will be investigated. Immune cell subtypes are causally involved in the formation and translation of preeclampsia by inducing an endothelial dysfunction which leads to cardiovascular damage.
To determine if the use of impedance cardiography can identify appropriate medications for use in treating morbidly obese patients to decrease the risk of preeclampsia.
This clinical investigation is a medical device trial to examine the safety and efficacy of TheraSorb sFlt-1 adsorber treatment of pregnant patients with preeclampsia.
Introduction Preeclampsia (PE) and intra-uterine growth restriction (IUGR) are two major pregnancy complications related to chronic utero-placental hypoperfusion. Three-dimensional power Doppler (3DPD) angiography has been used for the evaluation of utero-placental vascularisation and three vascular indices have been calculated: the vascularisation index (VI), flow index (FI) and vascularisation-FI (VFI). However, several technical endpoints hinder the clinical use of 3DPD as physical characteristics and machine settings may affect 3DPD indices, and so its clinical significance is not yet clear. Objectives The primary objective is to better understand the clinical significance of 3DPD indices by evaluating the relationship between these indices and placental morphometry. Secondary objectives are (i) to determine the impact of machine settings and physical characteristics on 3DPD indices, and (ii) to evaluate physio-pathological placental vascularisation patterns. Methods and analysis This is a prospective controlled study. We expect to include 112 women: 84 with normal pregnancies and 28 with PE and/or IUGR (based on our former cohort study on 3DPD indices for PE and/or IUGR prediction (unpublished data)). Within 72 h before planned or semi-urgent caesarean section, utero-placental 3DPD images with five different machine settings will be acquired. Placentas will be collected and examined after surgery and stereological indices (volume density, surface density, length density) calculated. The 3DPD indices (VI, FI and VFI) of the placenta and adjacent myometrium will be calculated. Correlation between Doppler and morphological indices will be evaluated by Pearson or Spearman tests. Agreement between 3DPD indices and morphological indices will be assessed by Bland and Altman plots. The impact of Doppler settings and maternal characteristics on 3DPD indices will be evaluated with a multivariate linear regression model.
The Biobank includes data and biological specimens of women from three original studies: 1) First-trimester Prediction of Preeclampsia (PREDICTION Study, NCT02189148), 2) Pre-Eclampsia And growth Retardation, an evaluative Longitudinal study (PEARL Study, NCT02379832), 3) Effect of Low Dose Aspirin on Birthweight in Twins: The GAP Trial (NCT02280031) and 4)PREDICTION2: Prediction of Preeclampsia and other Pregnancy Complications Following Combined Iterative Screening.
The use of spinal anesthesia in pre-eclamptic pregnant woman is of considerable benefit, as these patients present particular hazards with general anaesthesia, such as concerns for rapid airway control and cerebral blood flow alterations during induction of general anaesthesia and intubation However, the incidence of hypotension is high during spinal anesthesia for Cesarean section and it may approach values up to 95 %.
Introduction: An emerging body of evidence indicates that there is an association between air pollution exposure in pregnancy and adverse pregnancy outcomes (Rudra, Williams, Sheppard , Koenig, & Schiff, 2011; Dadvand, et al., 2013; Ritz, et al., 2014). Adverse pregnancy outcomes tend to lead to adverse neonatal outcome and a higher economic cost. Epidemiologic studies have also revealed that cardiovascular complications during pregnancy, such als preeclampsia, are associated with a greater cardiovascular risk during later life ( Abramson & Melvin, 2014). Aim: This study wants to examine the effects of exposure to environmental factors, polluents and particulate matter on the clinical pregnancy outcome for mother and child and to determine which biochemical changes in maternal, placental and cord blood best explain this effect. Methods: This study will be performed in a prospective cohort setup (n=200), recruited from the prenatal clinic in the University Hospital Antwerp. The data collection consists of four questionnaires (intake, both urine samples and postpartum), two blood samples (28 weeks and post-partum), two urine samples (20 and 30 weeks), two hair samples (20 weeks and post-partum), cord blood and the placenta. Results and conclusion: As the study will start in November 2014, no results are available yet.
Pregnancy elicits adaptive changes in uteroplacental blood flow, which are altered at high altitude and may contribute to the observed 3-fold increase in intrauterine growth restriction (IUGR) and preeclampsia (PreE). The investigators propose to collect myometrial, cord blood, and placental tissue samples from women at high altitude (Summit County) and low altitude (Denver) in Colorado in order to determine if residence at altitude during pregnancy changes the vasoreactivity of myometrial arteries (MA). If altered MA vasoreactivity is found, further studies may be able to link these changes to the increased rates of PreE and IUGR at altitude and contribute to the understanding of these two disorders.
A population-based prospective cohort design will evaluate the progression of urine congophilia in pregnancy using the Congo Red Dot test by following patients longitudinally across gestation in Bangladesh and Mexico City.
