Filter by:The primary purpose of the protocol is to compare the diagnostic accuracy in terms of positive and negative predictive values of Premaquick © (combined detection of IL-6 / IGFBP-1 total / IGFBP-1 native) and Quikcheck fFN ™ (fibronectin detection) tests for prediction of spontaneous delivery within 7 days in women with threatened preterm labor. The study hypothesis is that combined detection of IL-6 / IGFBP-1 total / IGFBP-1 native dice the admission will improve the prediction of delivery compared to the detection of fetal fibronectin alone in women with threatened preterm labor.
Preterm birth (PTB) is a major cause of perinatal morbidity and mortality. Worldwide, about 15 million babies are born too soon every year, causing 1.1 million deaths, as well as short- and long-term disability in countless survivors. Different strategies have been studied for prevention of spontaneous PTB (SPTB) in randomized controlled trials (RCTs), including progesterone, cerclage, cervical pessary, as well as lifestyle modification, such as smoking cessation, diet, aerobic exercise, and nutritional supplements. Most successful effort to reduce the incidence of SPTB have focused on asympatomatic women with risk factors, such as prior SPTB or short cervix. However, most SPTB occur in symptomatic women, i.e. women with preterm labor (PTL). Women with arrested PTL are at increased risk of SPTB. The cervical pessary is a silicone device that has been used to prevent SPTB. The leading hypotheses for its mechanisms are two: that the pessary helps to keep the cervix closed, and that the pessary changes the inclination of the cervical canal so that the pregnancy weight is not directly above the internal os. The aim of the study is to assess the efficacy of pessary in reducing preterm birth in women with arrested preterm labor
Antepartum hemorrhage is defined as bleeding from or within the female genital tract, occurring from 28+0 weeks of pregnancy and till delivery of the fetus. it occurs in 3-5% of pregnancies and is an important cause of perinatal and maternal morbidity and mortality worldwide
This will be a prospective study on labor characteristics, and obstetric and neonatal outcomes in women who accept and women who decline morphine as a form of pain management in labor. The study will also investigate patient satisfaction with this form of analgesia. The participants will be those who accept morphine and promethazine and those who decline morphine and promethazine for pain control.
Preterm birth is a common problem in obstetric care,with estimates ranging from 5% in several European countries to 18% in some African countries, Preterm labor defined as delivery before 37 completed weeks is the leading cause of perinatal and neonatal morbidity and mortality and strongly related to the developmental and neurological disabilities later in life.. There is still considerable uncertainty regarding the optimal progesterone type, route of administration, dosage and timing of start of therapy to prevent preterm labor in risky women
Membrane sweeping is a routine procedure in obstetrics in term patients. It has been shown to be effective in decreasing post term gestation and in increasing rate of spontaneous vaginal delivery when used in setting of induction of labor in nulliparous patients. The goal of this study is to determine if membranes sweeping in early labor is effective in improving delivery outcomes including decreasing rate of cesarean section.
to test the hypothesis that activity restriction in women with singleton gestations and with arrested PTL would reduce the rate of PTB.
Objective: To study the natural history of normal pregnancy and the most frequent pregnancy complications responsible for the excessive rate of perinatal morbidity and mortality, in order to develop models to predict the occurrence of these complications of pregnancy at the earliest possible time. The study focuses on the prediction of preterm labor with intact membranes, preterm prelabor rupture of membranes (PROM), preeclampsia, small for gestational age, gestational diabetes, and fetal death. These complications account for a minimum of $30 billion annually in the US alone. Study population: A cohort of pregnant women seeking care at the prenatal clinic of the Perinatology Research Branch in Detroit, Michigan. Design: A prospective observational cohort study of the natural history of women with a normal pregnancy, a history of adverse outcome, or those with a complication in the index pregnancy; therefore, this study will include nulliparous and parous women. Data will be collected at the time of clinic visits and will include interviews, clinical measurements, and ultrasound studies. We will assemble a biorepository of maternal biological fluids (blood, urine, saliva, cervicovaginal fluid, gingival crevicular fluid, swabs to characterize microbiota, amniotic fluid when a clinically indicated amniocentesis is performed). Placentas will be collected at the time of delivery as well as umbilical blood, and swabs to characterize the neonatal microbiota. We will use a retrospective case control and case-cohort design to generate models for the prediction of the most common pregnancy complications. These models will be developed by classifying obstetrical complications according to clinical presentation and histologic placental lesions. Models will be developed and subsequently validated in an independent cohort. Outcome measures: The goal is to develop sensitive, specific, and parsimonious predictive models to identify the patients at risk for developing complications of pregnancy using a combination of clinical and biological markers (biochemical and biophysical).
Study included all pregnant women admitted with threatened preterm labor during the study period. All participants underwent estimation of maternal serum homocysteine level and assessment of uterine artery Doppler indices.
Preterm labor is the first cause of hospitalization during the pregnancy, and at the origin of more than 60 000 births before 37 weeks of amenorrhea every year in France. It is however difficult to predict if a patient consulting in emergencies with symptoms of preterm labor, will give birth prematurely or not. Current diagnostic tools to identify patients with high risk of premature delivery in 7 days are insufficient because of their low positive predictive value. Yet the neonatal complications in case of premature delivery are important, with respiratory distress syndrome, hyaline membrane disease, necrotizing enterocolitis, intraventricular hemorrhage and post-natal death. Recent studies suggested that the detection of the placental alpha microglobulin 1 (PAMG-1) in the vaginal secretions, by Partosure® test at the women presenting symptoms of preterm labor with intact membranes would indicate that a premature spontaneous delivery could arise in 7 days with a good positive predictive value.The test is interesting all the more as the repetition of the prenatal cures of corticosteroids, aiming at the fetal lung maturation, is this day more recommended and as the beneficial effect takes place within 24 hours in 7 days following their administration. It seems thus essential to make studies to specify the interest of this test at the patients presenting a preterm labor. This study aims at estimating the diagnostic performance of the test of detection of PAMG-1 in the prediction of a delivery in 7 days, at the patients presenting symptoms of preterm labor.
