Active clinical trials for "Premature Birth"

This study is multicentered, prospective, randomized, opened, parallel, intervention study. The aim of this study is to evaluate the efficacy and safety of Montelukast sodium in the prevention of bronchopulmonary dysplasia (BPD) in preterm infant, below 32weeks gestational age. The investigators evaluate the first effectiveness through the morbidity and mortality of bronchopulmonary dysplasia. And then, the investigators evaluate the second effectiveness through the oxygen index, the usage of mechanical ventilator about taking medicine after 2 Weeks, Oxygen Utilization After 4 Weeks, Proinflammatory Cytokine through the bronchial lavage fluid.

The aim of this study is to examine the potential value of cervical length (CL) measurement with embryo transfer catheter in the prediction of spontaneous preterm deliveries in intracytoplasmic sperm injection (ICSI) cycles. Preterm birth is the leading cause of perinatal death and handicap in children. It is clear that ICSI pregnancies are at high risk groupfor preterm delivery (PTD). In singletons there is an estimated two-fold increased risk following ICSI. CL measurement with ultrasound in mid-trimester (22-24 weeks) is the best method for the prediction of PTD: The shorter the CL, the higher risk of PTD. Recent evidence suggests that at first trimester (11-13 weeks), the risk for PTD is inversely related to CL. It has been shown that the measurement of CL on pregnancy is an effective method for identification of the group at high risk for PTD. In embryo transfer, catheter is placed the through cervical canal. The method we will use in this study, CL measurement with transfer catheter, will give more precise results than measurement with ultrasound. No study has been performed to evaluate the prediction of PTD by analyzing measurements of CL, preconceptionally. Our study will be the first in this topic. There is a certain disadvantage of measuring CL during pregnancy: The effectiveness of prophylactic administrations (progesterone, cervical cerclage etc.) may be inversely related to the gestation at which treatment is initiated. If we know the risk of PTD before gestation, single embryo transfer will be preferred to avoid from multiple pregnancies that also increase the relative risk of PTD, in ICSI pregnancies.

The study hypothesis states that giving early enteral Vitamin D supplementation to preterm infants will decrease respiratory morbidity in extremely preterm infants.

The preterm birth is considered as a main problem in the modern obstetrics, being the responsible of greatest of 50% neonatal morbimortality and heavy costs. Despite the significant medical advances, the rate of prematurity has not declined over the past 40 years and even continues to rise in the developed countries. In order to decrease the prematurity is necessary that two premises: to identify the pregnant women at risk of preterm birth, and dispose of useful measures aimed at prolonging the pregnancy and therefore avoid preterm delivery. The investigators propose a clinical trial with the objective to identify effective strategies to reduce the premature birth (34 weeks and earlier) rate in the population of pregnant women at risk for premature birth, which will be identified by ultrasound during the second trimester of their pregnancy. The investigators intend to compare two accepted strategies: administration of progesterone (vaginally) or the placement of vaginal pessaries. These 2 strategies are affordable, easy to apply, and they present very few maternal-fetal secondary effects.

The study evaluates the efficacy of providing weekly iron-folate (IFA) supplements or Multiple Micronutrient (MM) supplements before pregnancy in increasing birth weight and duration of gestation as well as maternal and infant iron status.

The objective of this study is to evaluate the efficacy of an oral stimulation program on the length of the transition period in preterm infants (primary outcome), the length of hospital stay and the breastfeeding rates at discharge (secondary outcomes).

Hypothesis: Both nifedipine or progesterone are widely used in clinical practice as maintenance tocolytic therapy after an episode of threatened preterm delivery. Nevertheless, there is insufficient evidence to justify its routine use. The present study aims to evaluate the efficacy and safety of these tocolytic drugs for maintenance tocolysis in the management of threatened preterm delivery. Materials and methods: Phase III clinical trial, which evaluates the efficacy and safety of nifedipine and progesterone as maintenance tocolytic therapy until the 34th week of pregnancy in randomized women after an episode of threatened preterm delivery. Pregnant women with singleton pregnancies are going to be evaluated, with intact membranes and cervical length less than or equal to 25 mm, which have received acute tocolysis with atosiban. They will be randomized to receive maintenance tocolysis with nifedipine (60 mg / day orally) or progesterone (200 mg / day vaginally) until week 34 of gestation. Therefore all included patients will receive treatment with proven but not agreed efficacy, to decrease the recurrence of threatened preterm delivery, prolongation of gestation and subsequent better perinatal outcome. During the course of pregnancy, patients will be monitored in outpatient obstetrics, thus checking an adequate compliance. Monitoring will continue until the end with the delivery and collection of newborn data. The study will be single-blind, since there will be a blind evaluator. The drugs or treatments not allowed before and / or during the clinical trial are those which are indicated in the data sheet for each drug. If the patient takes antihypertensive treatment and continues it during pregnancy, dose adjustment will be done if it is needed. Data will be collected in the case report data (CRD). The end of the test will be considered when the last recruited patient complete the gestation (delivered vaginally or cesarean), and all data from newborn are collected. If a serious adverse event occurs in a patient, the woman will immediately finish the clinical trial and will be followed until complete resolution of the episode. Treatment is going to be considered effective if the birth occurs after 37 weeks of pregnancy with satisfactory perinatal outcome. The drugs are going to be considered safe if they do not cause adverse events in pregnant women, or if they are not serious. Number of Subjects: 50 pregnant women Diagnosis and main criteria for inclusion and exclusion: Inclusion Criteria Pregnant women with singleton pregnancies and intact membranes which have passed an episode of threatened preterm delivery (uterine contractions with cervical change) successfully treated with atosiban as acute tocolytic therapy. Cervical length ≤ 25 mm. Exclusion Criteria ≥ 3 cm cervical dilation, multiple pregnancy, maternal medical contraindication to tocolysis with nifedipine, atosiban or progesterone, or obstetric contraindication to tocolytic treatment (severe preeclampsia, intrauterine infection, placental abruption, fetal abnormality incompatible with life, fetal death) . Investigational product, dose and mode of administration: After a successful treatment of acute preterm labor with atosiban, is will be compared the safety and efficacy of maintenance tocolytic therapy with nifedipine 60 mg / day orally or progesterone 200 mg / day vaginally. Therapeutic group: C08CA05 Nifedipine. G03DA04 micronized progesterone. Route of administration: nifedipine orally. Progesterone vaginally. Dose: Nifedipine 60 mg / day. Progesterone 200 mg / day. Duration of treatment: From the resolution of acute episode of threatened preterm labor until 34 weeks of gestation. Reference treatment, dose and mode of administration: Current evidence questions the utility of maintenance tocolytic therapy. No reference treatment is currently defined.

The purpose of this study is to determine efficacy of vaginal and oral progesterone after tocolytic therapy in threatened preterm labor

This study plans to learn more about how to increase postpartum weight loss and how to decrease risk factors for postpartum women at increased risk for diabetes and heart disease. The program is delivered using a mobile application (app) and a lifestyle coach. This mobile application is developed for women who are at higher risk for diabetes and heart disease. Women who have gestational diabetes, (diabetes during pregnancy, or GDM), gestational hypertension (high blood pressure), and/or preeclampsia (high blood pressure and protein in the urine), and/or small-for gestational-age, and/or preterm (early) delivery during their pregnancies have a higher risk for diabetes and heart disease. This mobile application was developed using the latest research studies and using the evidence-based Diabetes Prevention and Colorado Weigh programs. The goal of the program is to help women lose weight and participate in physical activity after delivery.

More than 1.5 million HIV-infected women become pregnant each year. Approximately half have access to antiretroviral therapy (ART), but all are at increased risk of preterm birth (PTB). Vaginal progesterone (VP) is a promising and cost-effective intervention to prevent PTB that should be studied in this high-risk population. This pilot study will provide critical insight into the feasibility of a phase III trial by determining whether women are willing to participate, to adhere to study drug, and to complete follow-up.
