In this Journal Club episode, Ben and Daphna review a large national cohort study examining the association between antenatal corticosteroid exposure and survival in extremely preterm infants born between 21 and 24 weeks’ gestation. They discuss biologic plausibility, practice variation, and the challenges of interpreting retrospective data, while focusing on how these findings may inform counseling and shared decision-making at the margins of viability.

Ben and Daphna review the ICAF randomized clinical trial evaluating extended caffeine therapy in preterm infants and its impact on intermittent hypoxia through 41 weeks postmenstrual age. They discuss the study design, oximetry outcomes across multiple saturation thresholds, inflammatory biomarkers including TNF-α, and clinically relevant safety signals such as oxygen restart rates, length of stay, and weight gain. The conversation focuses on what intermittent hypoxia may mean for ongoing risk, and whether a targeted subgroup of infants might benefit from extending caffeine beyond traditional stopping points.

In this Journal Club episode, Ben and Daphna review a salient study from JAMA Network Open examining outcomes of infants born at 21 weeks’ gestation at the University of Iowa. They walk through resuscitation practices, early physiologic challenges, survival trends, and short-term developmental outcomes, while placing the data in the broader context of shifting limits of viability. The discussion highlights both cautious optimism and the many unanswered questions that remain as neonatology continues to push the boundaries of what is possible.
