Welcome to This Week in Pediatrics. This week we're covering 10 notable papers spanning neonatal intensive care and its aftermath, infant feeding and infection prevention, and the systems shaping adolescent health and safety. Let's dive in.

We start in the neonatal unit, where this week's papers question both what we add to treatment and what we give by default. In the European Journal of Pediatrics, Gonçalves-Ferri and colleagues studied very low birth weight infants under 1500 grams with moderate necrotizing enterocolitis. One Brazilian center added mild controlled hypothermia, targeting a core esophageal temperature of 35.5 degrees for 48 hours after diagnosis, and seven other centers providing standard care served as contemporaneous controls [1]. Among 285 infants, surgery was needed in about one in seven cooled infants compared with nearly half of controls, and after weighting for baseline differences the risk of surgery fell by roughly seventy percent. All-cause mortality risk was about forty percent lower, and severe neurological outcomes were similar between groups. These are striking numbers, but the design matters: this was a single intervention center compared against external controls, not a randomized trial, so differences in center practice could account for part of the effect. The authors frame hypothermia as a promising adjunct, and the finding mainly strengthens the case for a properly randomized multicenter trial rather than settling the question. Also in the European Journal of Pediatrics, Mari and colleagues report the first national estimate of culture-positive early-onset sepsis from Central-Eastern Europe, using Hungarian registry data from 2020 to 2023 [2]. Sepsis was uncommon, at about 0.4 per thousand live births, but far more frequent below 35 weeks of gestation. E. coli has overtaken group B strep as the leading pathogen, and roughly one in five infants with E. coli sepsis died, while no deaths were attributed to group B strep. Against that low incidence, nearly two thirds of infants treated in neonatal units received antibiotics, for a median of five days, and infants with early respiratory distress had about five times the odds of being treated. Lumbar puncture was performed in only about a fifth of culture-positive cases. As a retrospective registry study it cannot say which courses were unnecessary, but it adds to a broader body of evidence that empirical neonatal antibiotic exposure far outstrips the burden of proven infection.

Two reviews look beyond the acute phase. In Pediatric Research, Christensen and colleagues propose what they call the six Ps for infants born extremely preterm: post-discharge follow-up in neurodevelopmental programs, providing enriched environments, the physical environment, parent education, parenting style, and parent wellness [3]. It is a narrative review rather than new data, but it offers a structured framework for answering the question parents so often ask at discharge, which is what they can do for their baby. And in the European Journal of Pediatrics, Bufka and colleagues review vitamin B12 in early childhood with a focus on the mother-infant dyad [4]. Their key points are that infant deficiency usually reflects low maternal status, sometimes from unrecognized malabsorption even in omnivorous mothers, that neurological signs can appear before anemia or macrocytosis, and that methylmalonic acid and homocysteine help resolve borderline results. They also note that a normal newborn screen does not exclude deficiency developing later during breastfeeding, and that an unexpectedly high B12 level should not be equated with toxicity. Again this is expert synthesis rather than trial evidence, but it is a useful corrective for a commonly misread laboratory value.

Our second theme is what infants and children are fed, and how feeding can serve as both protection and a delivery vehicle for prevention. In Pediatrics, D'Hollander and colleagues followed more than 5,000 Toronto children from birth [5]. Each additional month of exclusive or any breastfeeding was associated with slightly lower body mass index scores and lower odds of overweight, and each additional month of formula feeding with the opposite. Per month, the effects were small, but they accumulate: formula feeding through 24 months was associated with roughly three quarters higher odds of overweight or obesity compared with exclusive breastfeeding to six months and continued breastfeeding to two years. This is observational cohort data, and with children followed to about three years of age on average, residual confounding by family factors remains possible, but it adds consistent evidence to the growth-related case for breastfeeding support. Also in Pediatrics, the American Academy of Pediatrics policy statement led by Ratner addresses unpasteurized milk, which remains legal for sale in at least 27 states [6]. The statement reviews infections from Listeria, Campylobacter, Salmonella, Brucella and E. coli O157, with particular risk to pregnant people, fetuses, infants and young children, and concludes that the claimed health benefits of raw milk have no evidence base and that pasteurized milk offers equivalent nutritional value without the infection risk. Moving to global child health, Nature Medicine published a pragmatic cluster-randomized trial from Cazes and colleagues in northern Nigeria [7]. Twenty clusters were randomized to routine immunization services alone or to the same services plus a monthly ration of small-quantity lipid-based nutrient supplements for children aged six to 23 months. Children in the supplement arm had roughly double the odds of card-verified first-dose measles vaccination, corresponding to about a twenty percentage point gain in coverage relative to control, even though just under half of children in intervention clusters had ever received the supplement. This is randomized evidence, though from a single region with high malnutrition and low coverage, and its generalizability to other settings has yet to be tested.

Our final theme concerns adolescent risk and the systems that respond to it. In Pediatrics, Forrest and colleagues compared child and adolescent all-cause mortality in the United States with 13 high-income peer nations from 1935 to 2023 [8]. Mortality fell dramatically everywhere, but less steeply in the United States, which crossed over to higher mortality than its peers in 1975 and has stayed there for five decades. Since 2006 the American decline has been roughly half as fast. By 2023 the gap was largest among 15 to 19 year olds, whose mortality was nearly three times that of peers, and this age group accounted for about forty percent of excess deaths, with males contributing most of that share. The analysis is descriptive and does not break down causes of death, but it locates the problem squarely in older adolescent boys. A second Pediatrics paper, from Gable and colleagues, examines one part of the crisis response [9]. In nearly 15,000 mental and behavioral health visits to an urban tertiary pediatric emergency department, about fifteen percent of youth arrived under an emergency hold, and the vast majority of those youth were Black and publicly insured, with nearly two thirds arriving with law enforcement. Holds and physical restraint both rose year over year, and holds were associated with restraint and with longer stays. Mobile crisis involvement was not associated with restraint, which the authors cautiously suggest may mitigate it. This is a single-center retrospective study, so the racial disparities and the mobile crisis signal call for confirmation elsewhere. Finally, the Academy's new policy statement on generative artificial intelligence, led by Suresh, also in Pediatrics, notes that large language models often underperform in pediatrics compared with adult specialties and carry risks of bias from nonrepresentative training data [10]. It calls for pediatric-specific validation, human oversight, postmarket surveillance, and disclosure of AI involvement in care, a framework rather than evidence of benefit.

If you only have time for one paper this week, make it the hypothermia study for necrotizing enterocolitis in the European Journal of Pediatrics [1]. It reopens the question of whether an inexpensive, familiar neonatal intervention could change the course of a disease where medical management has had little to offer, and its effect sizes are large enough that a randomized trial now looks overdue.

Here is what this week's evidence adds up to in Pediatrics. First, adjunctive mild hypothermia for moderate necrotizing enterocolitis was associated with much less surgery and lower mortality, but the evidence is nonrandomized and single-center, and it is not yet enough to change standard care. Second, national Hungarian data show early-onset sepsis is rare while neonatal antibiotic exposure is common, and E. coli now leads as the deadliest pathogen, adding weight to stewardship efforts, though which courses were avoidable remains unsettled. Third, longer breastfeeding was associated with modestly lower childhood overweight in a large Canadian cohort, observational evidence consistent with prior work, while a Nigerian randomized trial showed nutrition supplements roughly doubled the odds of measles vaccination in a high-need setting. Fourth, the American excess in adolescent mortality is five decades old and concentrated in older boys, and single-center data link emergency holds to restraint and marked racial disparities, with mobile crisis response a hypothesis worth testing rather than a proven fix. And finally, two Academy policy statements reaffirm that raw milk offers no proven benefit over pasteurized milk and that generative AI in pediatric care still lacks real-world pediatric validation.
