Active clinical trials for "Obstetric Labor, Premature"

Objective: The aim of this study was to investigate the efficacy of fetal right heart doppler findings in determination of pulmonary maturity. Materials and Methods: Pregnant women refered to the Department of Obstetrics and Gynecology at Karadeniz Technical University were included in the study. Pregnant women with pregestational or gestational diabetes mellitus, morbid obesity, thyroid dysfunction and fetal abnormality aneuploidy were not included in the study. The study was planned on women with late preterm and term pregnancy. Late preterm cases between 34-37 weeks were included in study group and term cases over 37 weeks were in control group. The doppler findings of main pulmonary artery and right pulmonary artery, mitral valve e/a wave ratio and lamellar body count were determined as the main outcomes. During caesarean section, 5cc amniotic fluid was taken to measure lamellar bodies count. Perinatal results of patients were recorded. p<0.05 was considered as statistical significance.

In this study, the levels of ischemia modified albumin, biglycan and decorin in the serums of pregnant women hospitalized for preterm labor will be examined. Their serum levels will be compared between women having preterm and term delivery. Their accuracy will be asessed in predicting preterm birth.

The purpose of this Quality Improvement initiative is to reduce severe morbidity and mortality among premature infants through proven and cost-effective clinical management during the antenatal, intrapartum, and postpartum periods. In order to reduce neonatal mortality and morbidity due to preterm birth complications, health facilities must be able to identify and manage women in preterm labor, accurately administer medications, and provide high-quality postnatal care.

The objective of the present study is to evaluate the effectiveness of two doses of vaginal progesterone(200mg versus400mg) and placebo in improving gestational age in twin pregnancy and its subsequent impact on perinatal outcome.

Prematurity is the most important cause of obstetric morbidity and mortality. Health centers and obstetricians are trying to reduce the preterm birth rate by taking into account the permanent effects of premature birth on human life in the early and long term. The most effective solution of preterm delivery is to determine the patients entering the risk group and to prevent preterm labor by putting the correct diagnosis at the right time. Recently, there have been studies on the efficacy of pessary practice in preventing preterm birth, but with the positive results of these studies, there has been hope for early birth prevention as well as other treatments. The aim of this study is; To assess the effectiveness of pessary use in patients with high risk for preterm labor and prophylactic cervical length less than 25 mm below 25 weeks and with a history of cervical insufficiency.

Nicorandil (potassium channel activator) is claimed to be as effective as Nifedipine (calcium channel blocker) for tocolysis in preterm labour aim of the study: To assess the efficacy of Nicorandil compared with Nifedipine as a tocolytic agent in delaying labour for 48 hours following their administration

Preterm birth (PTB) is the 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. Few prognostic tests are available to predict PTB. A short transvaginal ultrasound cervical length (TVU CL) has been shown to be a good predictor of PTB. Other strategies have been adopted for prevention of PTB. The evidence supports the use of vaginal progesterone in singleton pregnancies with short cervix. However, the predictive value of the research has recently been questioned, as the threat rate from preterms in the low-risk population has not decreased over time. Numerous clinical studies have been conducted to improve and identify effective prevention strategies in the threat of preterm birth. Among the parameters studied, in addition to the measurement of the uterine cervix and its complaints during the three trimesters of pregnancy, an evaluation of the cervical consistency index (CCI) was also proposed, i.e. an ultrasound evaluation of cervical softness.

Preterm birth (PTB) is a leading contributor to perinatal morbidity and mortality. While patients with preterm labor (PTL) are at an increased risk for PTB, not all PTL patients will deliver preterm. In patients with PTB, there is a high prevalence of 'intrauterine inflammation' as demonstrated by a large body of evidence. The presence of inflammation is noted by infiltration of inflammatory cells in the placenta and/or maternal fever in labor and/or elevation of cytokines in the amniotic fluid. Despite this significant association of inflammation with PTB, identification of women destined to deliver preterm by inflammatory markers in maternal blood has not been successful. To date, it has been difficult to determine which patients with PTL will experience PTB. Identification of biomarkers, such as high sensitivity C-Reactive Protein (hsCRP) as well as others such as sICAM, Pentraxin, sE-Selectin, and CxCL-10 in maternal serum and in placental cord blood, may help to serve three very important clinical aims. 1) Identification of novel biomarkers in maternal serum could help to distinguish those women with PTL who are most likely to deliver PTB. 2) These biomarkers may have a high negative predictive value and thus identify those women who are not likely to deliver preterm, avoiding undue hospital admission and medical therapies. 3) Select biomarkers in the mother and/or in cord blood may serve to identify those preterm neonates at greatest risk for adverse outcome. Through improved identification of these infants, studies with targeted therapies to reduce adverse neonatal outcomes in preterm neonates become feasible. This study involves a cohort assessment of women at risk for Preterm birth secondary to preterm labor, preterm premature rupture of membranes (PPROM), and cervical insufficiency (CI), between 22-0/7 and 33-6/7 weeks gestational age. We will obtain information regarding patients' pertinent past medical and obstetric history as well as small samples of maternal blood at up to four occasions, small samples of placental cord blood, a maternal saliva sample, and an infant buccal swab. We will follow each of these patient's pregnancy outcomes, and determine if there are any correlations between levels of certain biomarkers and latency to delivery as well as composite adverse neonatal outcomes. In women with PTB < 37 weeks, cord blood will be collected (as well as maternal saliva and an infant buccal swab) and biomarkers compared between those infants with and without specific adverse neonatal outcomes. Maternal saliva and buccal will be collected on all women and infants enrolled.

State of the question and research objective: International trials have shown that ultrasound measurement of the cervix identifies a population at high risk of preterm delivery. In case of short neck several types of treatments can be recommended: progesterone, the establishment of a strapping or pessary. These three treatments reduce the risk of preterm delivery. There is no French study. The objective of this study is to reduce prematurity in the PACA region Monaco-Corsica by introducing a routine ultrasound screening strategy asymptomatic short necks. Population concerned: All patients with active singleton pregnancy between 16 and 26 SA SA are eligible to ultrasound of the cervix. Primary endpoint: delivery rate before 37 weeks. Criteria secondary judgments rate of deliveries before 37 weeks, neonatal mortality morbidity. Expected result: a prematurity of 50%

This is a prospective observational trial that will enroll pregnant women between 24 and 36 6/7 weeks of gestation that present with signs and symptom of preterm labor with clinically intact membranes and cervical dilatation ≤ 3 cm and a control group of pregnant women without signs and risks for PTL to assess how the results of the novel kit for the detection of PAMG-1 in both patient groups correlate to their time-to-delivery (TTD) and other adverse neonatal and pregnancy outcomes. Thes study hypothesis contains that the novel diagnostic kit will identify women who are at high risk for preterm birth by a high positive predictive value.
