Active clinical trials for "Premature Birth"

Cervical length is a already known predictor for preterm labor. In this study the investigators want to examining the hypothesis that cervical curvature is also a predictor for preterm labor and that moderate transducer pressure influence cervical length. study population: 200 consecutive pregnant women between 14-34w, visiting in the ultrasound unit ether for routine screening or because of preterm labor. During their examination cervical length and curvature measurements will be taken. Another measurement will be taken after applying moderate cervical pressure. The investigators will compere cervical contour and pressure influence between groups and according to cervical length Demographic data will be taken at the time of recruitment and pregnancy outcome measures in a later telephone interview.

to evaluate if sonographic measure of short uterin cervix, sludge in amniotic fluid and abnormal doppler of the uterin artery can predict preterm labor

If we could prove that three -dimensional ultrasound measurement of fetal adrenal gland volume can accurately predict the likelihood of preterm birth in patients having symptoms and signs of PTL , we would be able to use it as a valuable component for assessment and early management of high risk pregnant women for PTB which can be positively reflected on the risk of neonatal morbidity and mortality in those patients.

Concentrations of micronutrients (especially purine and pyrimidine) in cord blood, blood of mothers and infants and human milk is studied

Beginning school is an important milestone for children. Children's readiness for school involves cognitive, physical, and emotional development. While the majority of children born preterm are able to transition from preschool to kindergarten with little difficulty, some children experience challenges during this time. Factors that negatively influence children's success in kindergarten include their age, socioeconomic status, neurological status and their ability to interpret sensory information from their environment. This study was planned to explain the relationship between the primary school readiness and the neurological status of preterm born children.

Assessment of correlation between vitamin D level and prevalence of preterm births remains limited. The exact role of vitamin D in preterm birth has not yet been clearly defined ,where some studies showed vitamin D deficiency increased the risk of preterm birth while other studies found no correlation. In this study will try to continue research on this subject.

To determine whether a novel ultrasonographic marker, uterocervical angle, correlates with risk of spontaneous preterm birth

Through a multicenter case-control study on the risk factors of premature ejaculation in Shaanxi, to find out the related factors of the occurrence and development of premature ejaculation, to provide reference for personalized treatment, in order to improve the quality of sexual life of patients and partners.

Prospective cohort study on pregnant women discharged from the hospital after the first episode of threatened preterm labor. Cervical length (CL) will be measured with transvaginal US upon initial presentation (i.e at the time of hospital admission), at the time of hospital discharge, and respectively 2, 4, 8 and 12 weeks later. Pregnant women undelivered after the 1st episode of threatened preterm labor will be invited to participate in the study if CL upon discharge is < 25 mm. The study will investigate the potential association between cervical shortening over time and time of delivery, to assess if spontaneous preterm delivery can be predicted by CL.

This study was designed to evaluate whether industrially prepared standardizing total parenteral nutrition is at least non-inferior to compounded TPN and provides nutritional intakes according to the new guidelines and provides the expected weight gain in preterm babies with a birth weight between 1250 and 2000g admitted in our NICU between 2015 & 2018
