Filter by:The purpose of this prospective study was to examine whether protein/creatinine ratios in catheterized urine specimens correlate to clean catch specimens in pregnant patients being evaluated for preeclampsia.
The goal of this study is to examine the activation of markers of endothelial and cardiovascular dysfunctions, from women with high-risk pregnancies. Information from this study will hopefully provide enough information to determine a link between race, the advent of high risk pregnancies and cardiovascular markers. With this information it might be possible to intervene with approved pharmacological treatments.
Use of Juice Plus+ food supplements, when initiated in the first trimester and used continuously thereafter, will result in a lower incidence of preeclampsia and pregnancy complications. This is a prospective randomized and blinded placebo controlled study sponsored by NSA, LLC of Memphis, TN.
The purpose of this study is to evaluate whether it is possible to detect changes in the concentration of PP13 in the blood of pregnant women who may go on to develop the complication of preeclampsia later on in the pregnancy, and if these changes can be detected early enough to allow early diagnosis and treatment for prevention of these complications and reduce their damage. This study will test if the PP13 biomarker during the first trimester of pregnancy has the ability to provide assessment of risk for the development of preeclampsia that necessitates delivery before 37 weeks gestation or can predict preeclampsia before 34 weeks gestation.
The purpose of this study is to evaluate the effects of oral L-Arginine in pregnant women with chronic hypertension.
Preeclampsia is a common disease state occurring in the third trimester of pregnancy, with an incidence of approximately 5-10% in the US. Hypertension (high blood pressure), a primary symptom of pre-eclampsia, may be present in women who were hypertensive prior to becoming pregnant.B-type (also known as brain) natriuretic peptide (BNP) is known to be made and released from the heart ventricles when the heart is strained. There is also evidence that BNP is secreted in the placenta, and may increase in preeclampsia and chronic hypertension in pregnancy.The purpose of the study is to determine if a maternal blood sample analyzed for the quantity of BNP is helpful in differentiating between pre-eclampsia and chronic high blood pressure.
This is a prospective multicentric study including four clinical units of Gynecology and Obstetrics (3 public health hospitals and one private team), one research team in Hematology and one Center of Clinical investigation (CIC). The objective is to identify, beside the pregnancy, in a population of patients with a preeclampsia (PE), with fetus presenting with growth restriction (IUGR) and a fetal demise (FD) a modification of circulating endothelial biomarkers compared with normal pregnancy. We want to understand better the physiopathology of preeclampsia and propose to patients with an endothelial dysfunction a early prevention of preeclampsia. Patients will be tested 3 times : At the pregnancy events; then 8 weeks and 12 months after the birth. Four groups will be constituted among patients: PE, IUGR, FD and normal pregnancy. Normal pregnancy will be tested as controls. The next pregnancy presenting in the unit to medical pregnancy follow up will be invited to participate. The main judgment criteria will be the levels of endothelial microparticles 8 weeks after the event. The study will last 3 years. The number of patient to include is 280.
An epidemiologic study of pregnant women in western Washington to measure the relationships between exposure to air pollutants and risks of preeclampsia and preterm delivery.
To assess the role of uterine artery and maternal serum leptin and lipids and their combination in screening for pre-eclampsia and small-for-gestational-age (SGA) fetuses at 20-24 weeks of gestation
Hypotension remains a common clinical problem after induction of spinal anesthesia for cesarean delivery. Maternal hypotension has been associated with considerable morbidity (maternal nausea and vomiting and fetal/neonatal acidemia). Traditionally, ephedrine has been the vasopressor of choice because of concerns about phenylephrine's potential adverse effect on uterine blood flow. This practice was based on animal studies which showed that ephedrine maintained cardiac output and uterine blood flow, while direct acting vasoconstrictors, e.g., phenylephrine, decreased uteroplacental perfusion. However, several recent studies have demonstrated that phenylephrine has similar efficacy to ephedrine for preventing and treating hypotension and may be associated with a lower incidence of fetal acidosis. All of these studies have been performed in healthy patients undergoing elective cesarean delivery. Preeclampsia complicates 5-6% of all pregnancies and is a significant contributor to maternal and fetal morbidity and mortality. Many preeclamptic patients require cesarean delivery of the infant. These patients often have uteroplacental insufficiency. Given the potential for significant hypotension after spinal anesthesia and its effect on an already compromised fetus, prevention of (relative) hypotension in preeclamptic patients is important. Spinal anesthesia in preeclamptic patients has been shown to have no adverse neonatal outcomes as compared to epidural anesthesia when hypotension is treated adequately. Due to problems related to management of the difficult airway and coagulopathy, both of which are more common in preeclamptic women, spinal anesthesia may be the preferred regional anesthesia technique. Recent studies have demonstrated that preeclamptic patients may experience less hypotension after spinal anesthesia than their healthy counterparts. To our knowledge, phenylephrine for the treatment of spinal anesthesia-induced hypotension has not been studied in women with preeclampsia. The aim of our study is to compare intravenous infusion regimens of phenylephrine versus ephedrine for the treatment of spinal anesthesia induced hypotension in preeclamptic patients undergoing cesarean delivery. The primary outcome variable is umbilical artery pH.
