Filter by:The primary objective of this study is to demonstrate that plasma concentrations of nucleosomes and free DNA differ between three groups: 1. pregnant patients with complications typical of placental insufficiency or venous thrombosis (group P), 2. healthy women (Group T1) and 3. healthy pregnant women (Group T2).
The objective of this study is to test the efficacy of low-dose aspirin (160 mg/day), given bedtime and started early during pregnancy (≤ 15 +6 weeks of gestation) in nulliparous pregnant women selected as "high-risk" by the presence of a bilateral uterine artery notch and/or bilateral uterine artery PI ≥ 1.7 during the first trimester ultrasound scan (11-13+6 weeks), to prevent the occurrence of pre-eclampsia or small for gestational age at birth.
Preliminary data from the investigator's lab identified novel patterns of differential DNA methylation in genes regulating cardiovascular and metabolic function in blood from women during the first trimester of pregnancy who were destined to develop preeclampsia (PE) in the third trimester. Further, common patterns of differential DNA methylation were found in the common genes from placental tissue at time of birth in the same women after diagnosis with PE, suggesting that the epigenomic patterns that predict pregnancy-induced hypertension may also underlie the development of chronic hypertension years after. It is unknown whether aberrant DNA methylation in pregnancy-induced hypertension is the mechanism by which chronic hypertension develops in these women remote from pregnancy nor is it known if hypertension remote from PE is as responsive to therapeutic treatment of hypertension compared to women who develop hypertension without history of PE. The investigators plan to objectively test the central hypothesis and attain the objective of this project
The present study examined the effects of Methyldopa on uterine artery diameter, uterine artery blood flow, umbilical artery and fetal middle-cerebral artery in patients with Preeclampsia, using Doppler ultrasound.
The purpose of this study to determine if measurement of maternal serum biomarkers and evaluation of the placenta by ultrasound can improve prediction of adverse pregnancy outcomes.
Kenya is one of the countries in sub-Saharan Africa that still experience high maternal mortality. For instance, in 2008/09 maternal mortality ratio was estimated to be 488/100,000 live births. Direct obstetric complications such as puerperal sepsis, postpartum hemorrhage, pre-eclampsia and eclampsia, obstructed labor and indirect causes including HIV, malaria and anemia in pregnancy are responsible for the majority of these cases. Just under 44% of births in Kenya are delivered under the supervision of a skilled birth attendant. The overall objective of this study is to determine the effect of provider type in the occurrence and management of serious childbirth related complications among postpartum women at the community level in Bungoma and Lugari Districts of Western Province, Kenya. The proposed study will employ a case control study design in which women with obstetric complication(s)will be cases and women without obstetric complications will be controls. Controls will be sampled concurrently with the cases. Each time a new case is diagnosed, a control is selected from the population at risk in the neighborhood at that point in time. The study population will consist of women aged 15-49 years with a delivery in the past 12 months. A woman who reports having experienced a birth-related complication will be recruited as a case while woman who reports having experienced no complication during child-birth will be recruited as a control.
The purpose of this study is to to test the feasibility of design methods and procedures for later use on a larger scale and to examine the acute and chronic effect of consumption of flavanol-rich chocolate on endothelium function and blood pressure in healthy pregnant women.
For the prediction of late-onset preeclampsia (PE) in low risk women, the investigators established a cut-off value for sFlt-1/PlGF ratio and evaluated the combination models of Elecys, second trimester uterine artery (UtA) doppler, and fetoplacental proteins for Down syndrome screening.
Preeclampsia complicates about 2-7% of pregnancies and is a major contributor to maternal and neonatal morbidity and mortality worldwide. Imbalance between circulating angiogenic and antiangiogenic factors has emerged as a potential key pathway in the pathophysiology of preeclampsia. Patients with preeclampsia have a higher circulating concentration of antiangiogenic factors (ie, soluble vascular endothelial growth factor receptor-1 [sVEGFR- 1], also called soluble fms-like tyrosine kinase 1 [sFlt1]) and soluble endoglin (sEng)] and a lower maternal circulating concentration of free angiogenic factors (ie, vascular endothelial growth factor [VEGF] and placental growth factor [PlGF]) than patients with a normal pregnancy. Bronchopulmonary dysplasia is the main respiratory sequelae of preterm birth. Its rate increased in preterm infants born from mother with preeclampsia. Recent studies showed that bronchopulmonary dysplasia is consistently accompanied by a reduction in the number of small arteries and on abnormal distribution of vessels within the distal lungs. This is associated with reduced lung VEGF expression. The main objective of this population-based study, ie in intra uterine growth restricted preterm babies born before 30 weeks of gestational age, was to examine whether levels of sFlt1 at birth in maternal and umbilical cord blood and in the amniotic fluid is associated with an increased risk of BPD.
Hypothesis : Vitamin D serum concentration is decreased in the first trimester in pregnant women who will develop preeclampsia in the second or third trimester compare to a control group Primary purpose : To determine the vitamin D status in the first trimester in a large population of french pregnant women in order to evaluate the importance of the vitamin D deficiency in France and correlate this deficiency with preeclampsia
