Repeatability of PDA diameter measurements on echocardiography.

Diameter of the patent ductus arteriosus (PDA) on transthoracic echocardiography (TTE) is used as a marker of haemodynamic significance. We aimed to assess the intra- and inter-observer variability in PDA diameter in babies born at ≤ 30 weeks' gestation. TTEs for 56 infants were performed by a single neonatologist.

Premature infants with patent ductus arteriosus: Postnatal growth according to type of management.

Background: Patent Ductus Arteriosus (PDA) is a common condition, affecting nearly half of infants born before 28 weeks' of gestation, and it has been associated with poor growth. It is not known if different treatment modalities are associated with more profound growth impairment. Our aim was to compare differences in weight gain at 36 weeks' corrected gestational age (CGA) in premature infants that received medical, surgical or conservative management for PDA.

Simprovisation: A model for student-led simulation.

Background: Simulation is well established in medical education, with scenarios designed by faculty members to elicit specific learning outcomes. We describe and evaluate a learner-led style of simulation-based education that puts learners in control of the day. Simprovisation harnesses the principles of socially constructed learning and andragogy, encouraging learners to address their own learning requirements.
