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.
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 is a unique collection of biological samples - such as blood, stool and saliva - collected from babies enrolled in the trial.
The CIRCA DIEM Study is a clinical research study being coordinated by the Developmental Chronobiology Team at The Kids Research Institute, who are based in Perth, Western Australia and involving research teams from Australia and New Zealand.
Preterm infants have immature control of breathing and impaired pulmonary gas exchange. We hypothesized that infants with bronchopulmonary dysplasia (BPD) have a blunted ventilatory response and peripheral oxygen saturation (SpO2 ) instability during a hypoxic challenge.
Abnormalities of the airway smooth muscle (ASM) layer in asthma may develop before birth. We hypothesize that antenatal inflammation causes physiological abnormalities of the ASM that predisposes asthma. This study determined the short-term effects of antenatal inflammation on the developing ASM.
Laboratory models provide an important tool in helping to understand the cellular and molecular drivers of respiratory disease. Many animal models exist that model the neonatal outcomes of preterm birth.
Inflammation and oxidative stress play a key role in the development of bronchopulmonary dysplasia (BPD), possibly contributing to persistent respiratory morbidity after preterm birth. We aimed to assess if inflammatory markers were elevated in exhaled breath condensate (EBC) of infants born very prematurely (< 32 weeks gestation) at 12-16 corrected months of age, and if increased levels were associated with BPD diagnosis and respiratory morbidity.
A Cochrane 2016 review indicated cycled light might benefit neonatal health in hospital. We systematically reviewed chronobiological factors for neonatal health in hospital units, identifying 56 relevant studies on light-dark cycles, feeding, noise, massage therapy, rooming-in, incubators vs. cribs, neonatal units vs. homes, and time-of-day of birth. Empirical evidence for benefits from chronobiology is weaker than expected, including light.
Understand how bronchopulmonary dysplasia (BPD) and antenatal and postnatal factors influence diaphragmatic functional effectiveness in very preterm infants.
