About this study

Official title: Impact of Threatened Preterm Labour in Fetal Cardiovascular and Metabolic Programming

The goal of this observational study is to learn about cardiac function and remodelling and metabolomic profiles in fetuses and infants who were exposed to a threatened preterm labor (TPL) during pregnancy.

Read the detailed description

The main questions it aims to answer are:

  • Evaluate the impact of threated preterm labour in cardiovascular and metabolic programming in fetal life and early infancy.
  • Describe prenatal and postnatal patterns of cardiac remodelling associated to threatened preterm labour.
  • Describe fetal growth patterns associated to threatened preterm labour.
  • Describe metabolomic profiles in umbilical cord blood associated to cardiovascular programming in fetuses exposed to threatened preterm labour.

The study's main tasks are:

  • To perform an antenatal echocardiography of the exposed cohort is performed during the admission due to TPL or preterm spontaneous rupture of membranes (SRM).
  • All participants are asked to fill a diet and stress questionnaire.
  • To collect cord blood at the time of delivery.
  • To perform a postnatal echocardiography six months after birth.

Researchers will compare fetuses and infants who were exposed to TPL to those who were not exposed to TPL during pregnancy to see if threre are any differences in cardiac function and remodelling.

Secondary outcomes (3)
  1. Adherence to Mediterranean diet

Questions about this trial

What is this clinical trial studying?

An observational study of Obstetric Labor, Premature, run by Instituto de Investigación Sanitaria Aragón at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Cristina Paules, MD, PhD (650589500, cristinapaules@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fetal cardiac sphericity index (time frame: 24 - 36+6 weeks of gestation). The study lists 19 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05670665, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jan 2023.
