Pediatricians Sound the Alarm on Trump Executive Order Targeting Childhood Vaccine Schedule | Chicago News | WTTW
“There’s no practical way to actually implement that executive order.” · The order also recommends that several vaccines, including those for hepatitis A, hepatitis B and meningitis, be given only to high-risk groups rather than all children.

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.
Research of the Day
Social Media Use and Depression in Early Adolescence: Longitudinal Analysis
This 3-year longitudinal study followed 6,500 adolescents ages 12-15, tracking social media use patterns and mental health outcomes. High social media use (>3 hours/day) was associated with increased depression risk, though the relationship was bidirectional.
Key findings: (1) 35% increased odds of elevated depressive symptoms with high use; (2) Social comparison and cyberbullying mediated the relationship; (3) Active use (creating content) showed smaller associations than passive consumption.
Screen for problematic social media use during well visits. Counsel families on media limits, encourage active over passive use, and discuss warning signs of cyberbullying and unhealthy comparison.
Popular Beliefs
Green mucus means bacterial infection requiring antibiotics
What the evidence shows: Mucus color changes naturally during viral infections and does not reliably distinguish viral from bacterial causes. Green/yellow mucus indicates immune cell activity, which occurs in both viral and bacterial infections. Antibiotics should be prescribed based on clinical criteria, not mucus color.
Letting babies walk early causes bowlegs
What the evidence shows: There is no evidence that early walking causes bowlegs. Most infants have some degree of bowing that typically resolves by age 3-4. Pathologic bowing has other causes (Blount disease, rickets). Encourage normal motor development and monitor for asymmetric or progressive bowing.
Starve a fever, feed a cold
What the evidence shows: Neither fevers nor colds benefit from restricting food. Both conditions increase metabolic demands, and adequate nutrition supports immune function. Encourage normal eating as tolerated and emphasize hydration with any illness.
Behaviors
Musical Training and Brain Development in Children: Longitudinal Neuroimaging Study
This 3-year study compared brain development in children receiving musical instrument training versus those doing sports or no organized activity. Music training was associated with enhanced auditory processing, motor coordination, and executive function networks.
Key findings: (1) Increased cortical thickness in auditory and motor regions; (2) Better performance on working memory and attention tasks; (3) Benefits correlated with practice duration.
Music education offers cognitive benefits beyond artistic development. When families ask about extracurriculars, mention music as a brain-healthy option. Benefits appear even with modest practice time.
Genetics
Genetic Testing in Hypertrophic Cardiomyopathy: Sports Participation Guidance
Updated guidelines incorporate genetic testing results into sports participation decisions for young athletes with HCM. Some genetically positive but phenotypically negative individuals may safely participate in athletics with appropriate monitoring.
Key findings: (1) Risk stratification improved with genetic markers; (2) Shared decision-making framework more nuanced than previous blanket restrictions; (3) Regular cardiac monitoring essential regardless of sport participation.
Genetic testing can refine, but not eliminate, cardiac risk assessment. Refer to cardiology for any athlete with suspected or confirmed HCM. Shared decision-making with families is appropriate.
