Professional Corner: Pediatricians Call for New Border Protections, AMA Awards $1 Million in Grants and More
The AHA opens its health tech competition, AMA awards $1 million in community grants, and pediatricians call for stronger protections for children at the US border.
Early Antiviral Therapy Linked to Reduced Risk for Influenza-Related Hospitalization in Children
Antiviral treatment started within 48 hours of symptom onset is linked to a reduced risk for hospitalization among pediatric patients with influenza.
Two unvaccinated people die of measles in Pennsylvania outbreak, health officials say
Children as young as 6 months are eligible for an early, extra dose of the MMR vaccine during outbreaks. “When enough eligible individuals receive the vaccine, the entire community develops a level of immunity that protects our most vulnerable, ...
Research of the Day
Inhaled Corticosteroid Adherence in Minority Children: Community Health Worker Intervention
This RCT evaluated community health worker (CHW) home visits to improve inhaled corticosteroid adherence in 400 minority children with persistent asthma. CHW intervention nearly doubled medication adherence rates.
Key findings: (1) Adherence improved from 45% to 82% in intervention group; (2) 50% reduction in asthma-related ED visits; (3) Culturally tailored education more effective than standard approach.
Consider CHW programs or similar support for families struggling with asthma medication adherence. Address social determinants and provide culturally appropriate education.
Popular Beliefs
Organic food is significantly more nutritious
What the evidence shows: Organic foods have lower pesticide residues, but studies show minimal nutritional differences compared to conventional foods. What matters most for health is eating a variety of fruits and vegetables, whether organic or conventional.
Teething causes high fevers and diarrhea
What the evidence shows: While teething may cause mild symptoms (gum irritation, drooling, slight temperature elevation), it does not cause high fever (>102°F/38.9°C) or diarrhea. These symptoms should prompt evaluation for other causes. Attributing significant illness to teething may delay diagnosis of serious conditions.
Wait 30 minutes after eating before swimming
What the evidence shows: There's no evidence that swimming after eating causes cramps or drowning. While digestion diverts some blood flow to the gut, it doesn't impair swimming ability in normal circumstances. Common-sense supervision is always important regardless of meal timing.

Screen Time and Executive Function in Preschoolers: A Longitudinal Analysis
This prospective cohort study followed 850 children from ages 2 to 5 years, examining the relationship between screen time exposure and executive function development. Researchers used validated parent-report measures and direct assessments of working memory, inhibitory control, and cognitive flexibility.
Children with more than 2 hours of daily screen time at age 2 showed lower scores on executive function measures at age 5. Notably, the type of screen content mattered—educational programming showed smaller associations than passive entertainment viewing. Joint parent-child viewing partially mitigated negative effects.
These findings support counseling families on the AAP recommendation of less than 1 hour per day of high-quality programming for children 2-5 years. Emphasize co-viewing and educational content when screens are used. Executive function is crucial for school readiness and later academic success.
Genetics
Genetic Predictors of Peanut Allergy Persistence
Genome-wide association study identifies genetic variants associated with peanut allergy persistence versus resolution. Children with certain variants are more likely to outgrow their allergy, informing timing of oral food challenges.
Key findings: (1) 4 genetic variants strongly associated with persistence; (2) Genetic testing could reduce unnecessary avoidance and challenges; (3) Environmental factors remain important in allergy development.
Genetic testing may soon help predict which children will outgrow allergies. For now, continue regular reassessment with IgE testing and oral challenges as clinically indicated.
