Active clinical trials for "Obstetric Labor, Premature"

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.

Detection of short cervix by transvaginal ultrasound and its evidence based management to prevent preterm birth .

The aim of this study is to assess whether or not the emergency tocolytic effect of combined nifedipine and sildenafil citrate will have a superior effect over nifedipine alone in terms of inhibiting eminent preterm labor and improving perinatal outcomes.

This study will follow pregnant women who are taking indomethacin as Standard of Care (SOC) for the indications of preterm labor (PTL), short cervix, or other indications, to evaluate the pharmacokinetics (PK), what the body does to the drug, and pharmacodynamics (PD), effectiveness of the drug in treating the specific intended disease process of this medication. This will help us develop more information for medication dosing specific to pregnant women experiencing preterm labor. Indomethacin is often prescribed to pregnant women presenting with preterm labor or shortened cervix, which places them at risk for preterm labor and delivery. Indomethacin has been used since the 1970s to prolong pregnancy by decreasing uterine contractions. However, despite the widespread use of indomethacin in pregnancy, there is limited information available to help physicians determine how much indomethacin to prescribe and how often to prescribe it.

Children born prematurely are of greater risk of developing chronic lung disease (Bronchopulmonary Dysplasia). With an increase in the amount of premature children, we expect an increasing number of children with BPD. Today we do not have many ways of predicting or treating this condition, and the children are usually in hospital for several months after birth. Many are dismissed with home oxygen. Children with BPD are typically often re-submitted to hospital with respiratory disease the first couple of years, and some of them have problems throughout childhood and into adulthood. Other scientists have found a correlation between BPD and Chronic Obstructive Pulmonary Disease (COPD). The condition as well as the treatment (steroids), are associated with great risk of adverse effects as Cerebral Palsy, blindness, deafness and mental retardation. The investigators wish to find a safe way to identify the children in greater risk of developing BPD, who could therefore benefit from a more intensive treatment.An early diagnosis would increase the possibility of predicting the prognosis. Other studies have proven a connection between both low vitamin A and D and high exhaled nitrogen oxide (NO) with lung disease. With this trial the investigators wish to make a reference material for NO and vitamins A and D in infants admitted to the neonatal department at two hospitals in Denmark, both with and without treatment with nasal Continuous Positive Airway Pressure. The investigators furthermore wish to describe an eventual connection between BPD and these factors by examining a large group of children on 7 specific occasions within the first two months of life and at a one year follow up.

This study looks at the effects of a mother's genes and other characteristics (mother's age, baby's age, race, and other diseases) on the ability of nifedipine to end contractions and prevent an early delivery. This information will be used to decide what amount of nifedipine women need to best treat preterm contractions.

This observational study aims to test the level of parathyroid hormone in pregnant women. The main question it aims to answer is: n Pregnant women, are the levels of serum PTH, calcium, magnesium, phosphorus & albumin similar in both preterm and term births?

RESEARCH HYPOTHESIS -Incidence of preterm delivery is lower in women treated with oral micronized progesterone (Utrogestan) as acute tocolysis agent compare to Nifedipine group with fewer maternal side effect

The investigators will study 200 women with singleton pregnancies presented with prelabor preterm rupture of membranes or undergoing cesarean section (CS). Amniotic fluid lamellar body count (LBC) and fetal pulmonary artery Doppler will be done to all women. LBC and fetal pulmonary artery Doppler will be correlated with fetal outcome

Preterm birth (PTB) is the primary cause of infant death worldwide. It has been shown that a vaginal microbiota deplete in Lactobacillus species is a risk factor for preterm labour. Conversely a vaginal microbiota dominated by Lactobacillus crispatus appears to be protective for these adverse outcomes. A wide range of 'over the counter' Lactobacillus spp. containing products targeted at 'vaginal health' and formulated for vaginal administration are available, but most of them do not contain vaginal species of Lactobacillus. The primary aim of this study is to determine whether vaginal supplementation with L. crispatus CTV-05 is associated with colonisation.
