Plain English summary of protocol

Background and study aims
Some babies born very early (prematurely) can develop a serious lung condition called broncho-pulmonary dysplasia (BPD). This condition can affect their growth, brain development, and heart and lung health later in life. Doctors and researchers believe there may be different types of BPD, each developing in its own way, but we don’t yet fully understand how or why. This study aims to learn more about the different forms of BPD and how they develop, which could help improve care for these babies in the future.

Who can participate?
Any newborn baby born before 30 weeks of pregnancy (gestational age) can take part in the study.

What does the study involve?
The study does not involve any extra tests or procedures. It simply uses information that is already being collected as part of the baby’s normal hospital care. This includes things like data from breathing support machines, vital signs monitoring, and routine lung scans.

What are the possible benefits and risks of participating?
There are no risks to taking part in the study because nothing about the baby’s care will change. The information collected could help doctors better understand BPD and eventually lead to more personalised treatments for babies with different types of the condition.

Where is the study run from?
The study is being carried out in several specialist newborn intensive care units and research centres across Europe.

When is the study starting and how long is it expected to run for?
The study is already underway and is expected to continue until sometime in 2026, depending on how many babies are enrolled.

Approved 05/07/2023, Junta de Andalucia - Comité ed Ética ed al Investigación de Cádiz (Avenida Ana deViva, 12- 11009 Cadiz, Cadiz, 11009, Spain; +34 950002100; ceic.hpm.sspa@juntadeandalucia.es), ref: TFG-LUSNEO1-2023

Health condition(s) or problem(s) studiedBroncho-pulmonary dysplasia
InterventionAnalysis of clinical, imaging physiological and vital data routinely collected during NICU care.
Intervention typeOther
Primary outcome measureGas exchange metrics, lung aeration, vital functions, respiratory support and lung mechanics data are registered at 10, 21 and 28 days of life as well as at 34 and 36 weeks post-conceptional age. Measurements are performed with commonly used techniques such as transcutaneous blood gas monitoring, blood gas analyses, quantitative lung ultrasound, electrical cardiometry, pulsoxymetry and the measurements shown by mechanical ventilators screens, as per clinical routine
Secondary outcome measuresThere are no secondary outcome measures

Age groupNeonate
SexBoth
Target number of participantsA convenience sample size of approximately 300 participants is expected to be enrolled. However, since this is the first study on pathophysiological phenotypes of BPD, a formal sample size calculation is unfeasible
Key inclusion criteriaPreterm neonates (GA <=30 weeks)
Key exclusion criteria1. Complex malformations or chromosomal abnormalities
2. Congenital lung anomalies
3. Pneumothorax, pneumomediastinum or pleural effusion
4. Need for surgery
5. Severe hemodynamic instability (defined as any need for inotropes) at any time during the study

IPD sharing plan summaryAvailable on request
Publication and dissemination planStudy results will be diffused via one or several articles representing subsection of the study published in major international journals in the field of "critical care" or "pediatrics". Partial results will also be presented at the main conferences in the field (such as PAS, ATS or ESPNIC)
IPD sharing planThe anonymised datasets generated and analysed will be available upon adequate request from researchers, respecting all relevant regulations. They will need to be requested to the main study contact (see above) and the establishment of a CDA may be needed.
