Which babies with critical congenital heart disease face the highest risk of brain injury, and does earlier surgery actually help? Why is infant CHD mortality climbing again after years of decline, and who's most affected? Can a mother's cardiovascular status in preeclampsia predict her newborn's circulatory transition? This week's Journal Club brings together five conversations on CHD, maternal-fetal physiology, and vaccine policy. Nim and Adrianne cover a meta-analysis on brain injury in critical CHD, a 25-year national mortality study, a pilot study on preeclampsia and neonatal cardiac output, and a look at RV diastolic function after CHD intervention. Ben and Eli close with Neo News on a controversial hepatitis B vaccine trial in Guinea-Bissau.

In this episode of Neo News, Ben and Eli break down a troubling story in vaccine policy: an unsolicited $1.6 million CDC grant funding a Danish research group's trial in Guinea-Bissau, one designed to withhold or delay the hepatitis B birth dose from thousands of newborns in a country where the disease is highly endemic. They trace the ethical parallels to Tuskegee, the funding irregularities, and the pushback from the Africa CDC that halted the study. They also cover the clinical stakes clinicians face daily, including age-dependent chronicity and the real risks of a "safe" two-month delay. A candid, unfiltered conversation about advocating for evidence-based care when the evidence itself becomes politicized.

In this prospective study, Adrianne and Nim dig into an area with almost no normative pediatric data: right ventricular diastolic function. Comparing 57 infants with RV pressure overload after intervention for pulmonic stenosis or tetralogy of Fallot to 134 healthy controls, the authors found a consistent pattern, reduced beat-to-beat variability, a higher atrial contribution to filling, and an E/A ratio inversion that was nearly universal in the CHD group versus about half of controls. It's one of the first real attempts to define what a right-sided diastolic pattern actually looks like in this population. But without a comparison against cardiac catheterization, the hosts agree the findings are hypothesis-generating at best, a starting point for a multi-parametric approach, not a reason to skip an invasive workup.

In this small prospective pilot study, Adrianne and Nim explore a domain rarely discussed on rounds, how a mother's cardiovascular function in preeclampsia shapes her newborn's circulatory transition. Using maternal echo and neonatal electrical cardiometry across 13 mother-baby dyads, the authors found an inverse relationship: the worse the mother's cardiac function, the higher the neonate's cardiac output, though vascular tone barely budged. It's a compelling hypothesis about placental strain and fetal adaptation. But Nim pushes back hard on the methodology, pairing this paper with a companion study showing electrical cardiometry consistently overestimates cardiac output in neonates, and questioning why daily echoes were performed on these babies but the results never reported.

In this retrospective national study, Adrianne and Nim look at 25 years of congenital heart disease mortality in the US using CDC WONDER data. Infant mortality remains staggeringly high (54 per 100,000), and after years of steady decline, it has been climbing again since 2014. Disparities run throughout: higher deaths among males, non-Hispanic Black and American Indian/Alaska Native populations, and in rural, Midwestern regions, pointing more to gaps in access and resources than to disease biology. The conversation also flags a growing, under-discussed problem, an aging adult congenital population outpacing the pediatric one for the first time, with too few specialists trained to care for them.

In this systematic review and meta-analysis, Nim and Adrianne dig into just how common brain injury really is in neonates with critical congenital heart disease. Pooling 31 studies spanning two decades, the authors found that nearly 70% of these babies show some form of ischemic brain injury, split roughly between pre-operative and post-operative timing. Counter to what most clinicians would predict, kids who went to surgery earlier (days 4-6) had higher rates of white matter injury than those who waited longer. MRI remained the most sensitive tool for picking up these lesions, well ahead of ultrasound or CT. But the data stops well short of proving these findings predict long-term outcomes, and Nim pushes back on the idea that an abnormal scan alone should steer decisions about whether to operate.

What if communication were treated as a procedure, something we train for and get feedback on, just like an intubation?  In this episode of Neo News, Eli Cahan talks with Dr. Jessica Fry of Northwestern University and Lurie Children's Hospital about her NeoReviews piece, "Recognizing Communication as a Procedural Skill in Neonatology." Dr. Fry shares the personal loss that shaped her career, the ethical stakes of getting family communication right, and how trauma-informed care can guide something as simple as how we address parents on rounds. They discuss the critical first 48 hours after admission and how simulation-based training can build real skill over time. A candid look at a skill every NICU provider uses daily, and how we can all get better at it.

How far has delivery room ventilation really come? In this special episode, recorded in collaboration with the Neonatal Resuscitation Symposium, Ben sits down with Dr. Charles Roehr, professor of neonatology and perinatal medicine at the University of Bristol, clinical trialist at the University of Oxford, and member of ILCOR. Together they trace the evolution of respiratory support at birth, from the era of fixed inflation breaths to today's focus on physiologic stability and gentle cardiopulmonary transition. Dr. Roehr reflects on a quarter century of resuscitation science, the enduring challenge of human factors in the delivery room, and where the field may be heading, from better intrapartum monitoring to increasingly specialized resuscitation teams.

Dr. Roehr will be delivering a keynote, "Optimizing Effective Ventilation Strategies in the Delivery Room," at the Neonatal Resuscitation Symposium, taking place September 10 to 11 at Indiana University in Indianapolis.

Which PDAs actually need treatment? Can maternal voice and scent shape language outcomes? Should we cool at 35 weeks? And did stepping away from probiotics come at a cost? This week’s Journal Club takes on five papers that push back on standard practice. Ben reviews the SMART-PDA trial and a comparative study of PDA pharmacotherapy, Daphna covers the MIND trial on multisensory maternal interventions and a Pediatrix database study on NEC after the FDA probiotic warning, and Ben rounds out the main segment with a national look at hypothermia in 35-week infants with HIE. Ben and Eli wrap the week with Neo News on rising vitamin K refusal.

Vitamin K refusal has crossed 5%. That's one in twenty babies, and the curve is bending the wrong way. Ben and Eli work through a new Pediatrics case review that opens with a warning shot, that hemorrhagic presentation in an infant should no longer be a diagnostic mystery, alongside a JAMA letter tracking refusal from 2.9% in 2017 to 5.2% in 2024. Eighty-one times the risk. Intracranial hemorrhage in most late-onset cases. Twenty percent mortality. They talk about the halo effect on other refusals, the ICD code you should be using, and why this conversation belongs in the obstetrics office, not the nursery.
