Importance: Preterm infants are recommended to receive most vaccinations at the same postnatal age as term infants. Studies have inconsistently observed an increased risk for postvaccination apnea in preterm infants.
Objective: To compare the proportions of hospitalized preterm infants with apnea and other adverse events in the 48 hours after 2-month vaccinations vs after no vaccinations.
Objective: We aimed to determine the incidence of growth failure in infants with necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP) and whether initial laparotomy versus peritoneal drainage (PD) impacted the likelihood of growth failure.
Summary Background Data: Infants with surgical NEC and SIP have high mortality, and most have neurodevelopmental impairment and poor growth. Existing literature on growth outcomes for these infants is limited.
Objective: To assess the risk of cognitive impairment among infants born extremely preterm using the INTERGROWTH-21st standards.
Study Design: We analyzed anthropometric data at birth and 36 weeks postmenstrual age (PMA) from infants born extremely preterm (24-26 weeks of gestation) admitted to US neonatal units between 2008 and 2018. To determine INTERGROWTH-21st z-score values that indicate an increased risk of cognitive impairment at 2 years of age (Bayley cognitive score <85), we employed classification and regression trees and redefined growth failure (weight, length, and head circumference z-scores at 36 weeks PMA) and growth faltering (weight, length, and head circumference z-score declines from birth to 36 weeks PMA).
Ankyloglossia refers to a congenitally tight lingual frenulum that limits the motion of the tongue. Whether the release of a tight lingual frenulum in neonates improves breastfeeding is not clear. Because many of the symptoms of ankyloglossia overlap those of other breastfeeding difficulties, a team partnership is necessary.

- Food insecurity during pregnancy is linked to negative outcomes for mothers and newborns, and opioid use may increase the risk of food insecurity among pregnant mothers.
- The study analyzed data from 254 mothers, finding that 23% experienced food insecurity, which was notably higher among mothers who used opioids, had public insurance, faced housing instability, and experienced trauma.
- Mothers facing food insecurity were less likely to receive adequate prenatal care, emphasizing the need for targeted interventions and screenings for at-risk populations, particularly those with opioid exposure.
