CIRCA DIEM

The CIRCA DIEM Study is a clinical research study being coordinated by the Chronobiology Team at The Kids Research Institute Australia, who are based in Perth, Western Australia and involving research teams from around the world.

Participating Sites and Investigators

The CIRCA DIEM Study is a multicentre study, involving several different hospital sites across Australia. Here, you can find out more about which hospitals recruit babies into the CIRCA DIEM Study.

Data Safety Monitoring Committee

The Data Safety Monitoring Committee (DSMC) is an independent group of experts that oversees participant safety and the integrity of the CIRCA DIEM Study.

The CIRCA DIEM Biobank

The CIRCA DIEM biobank is a unique collection of biological samples - such as blood, stool and saliva - collected from babies enrolled in the trial.

Comparison of "IN-REC-SUR-E" and LISA in preterm neonates with respiratory distress syndrome: a randomized controlled trial (IN-REC-LISA trial)

Surfactant is a well-established therapy for preterm neonates affected by respiratory distress syndrome (RDS). The goals of different methods of surfactant administration are to reduce the duration of mechanical ventilation and the severity of bronchopulmonary dysplasia (BPD); however, the optimal administration method remains unknown. 

Respiratory and chest wall mechanics in very preterm infants

Data on static compliance of the chest wall (Ccw) in preterm infants are scarce. We characterized the static compliance of the lung and Ccw to determine their relative contribution to static compliance of the respiratory system in very preterm infants at 36 wk postmenstrual age. We also aimed to investigate how these compliances were influenced by the presence of bronchopulmonary dysplasia and impacted breathing variables.

Prognostic Accuracy of BPD Definitions for Long-Term Outcomes in Preterm Infants: A Systematic Review

Since the first description of bronchopulmonary dysplasia (BPD), multiple definitions to diagnose BPD and its grading have been published. Several studies have compared the predictive performance of these definitions for long-term outcomes. The objective was to identify the BPD definition with the optimal predictive performance for long-term respiratory and neurological outcomes in preterm infants.
