What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at whether a special ultrasound technique called fetal lung elastography can predict respiratory distress syndrome (RDS) in preterm babies. Researchers measured lung stiffness in 80 unborn babies between 24-33 weeks of pregnancy and compared those who later developed RDS with those who did not. The goal was to see if this non-invasive test could help doctors identify high-risk babies before birth.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a non-invasive ultrasound test that helps doctors predict which preterm babies are at risk for breathing problems, allowing for better preparation and care.
What could go wrong
This is a small, completed observational study, not a treatment trial. The results may not be conclusive or generalizable to all pregnancies, and the technique may not be accurate enough for routine use.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study will include single pregnant women with maternal age of 18-45 years, gestational age between 24-34 weeks, diagnosed with preterm labor, amniotic fluid pathology, fetal congenital and chromosomal anomalies, and fetuses without fetal congenital and chromosomal anomalies, who were hospitalized in the ward after the application to the Perinatology Clinic of Etlik City Hospital. A total of 80 patients without systemic maternal disease findings and diagnoses, without chronic drug use, who were measured at least 24 hours after antenatal corticosteroids were administered and delivered within a maximum of 72 hours, will be included in our study as two case groups with and without RDS diagnosis in neonatal follow-up.
