30-Second Takeaway
- Early epilepsy surgery in selected infants can markedly improve seizure control and neurodevelopmental trajectory.
- Supplemental early parenteral amino acids in ELBW infants did not improve school-age cognition and may harm strength.

Random‑effects model choice alters heterogeneity interpretation but not mean cognitive effect
Meta-analysis of 58 cohorts comparing cognitive outcomes in preterm versus term children showed similar mean effect estimates across 7 random-effects models. Between-study variance interpretations varied: asymmetric models flagged extreme studies and DP models revealed study clusters by characteristics. Authors conclude model choice aids exploration of heterogeneity and study-level features rather than changing the pooled mean. Implication: use alternative random-effects models to probe heterogeneity when synthesizing pediatric cognitive studies.
Extra 1 g/d parenteral amino acids for 5 days in ELBW infants showed no cognitive benefit
In this double-blind RCT of ELBW infants, additional 1 g/d parenteral amino acids for 5 days did not increase survival without neurocognitive impairment at school age (21% vs 23%). Children in the amino-acid arm had lower relative handgrip strength (adjusted mean difference -0.39; 95% CI, -0.65 to -0.13). There was a possible higher risk of low psychosocial functioning in the amino-acid group (26% vs 18%; aRD 10.7%; 95% CI, -1.3 to 22.6). Recommendation: do not adopt routine extra early parenteral amino acids for ELBW infants to improve long-term neurocognition.
Early neurodevelopmental impairment is common after infant cardiac surgery; genetics and diagnosis matter
Cross-sectional registry analysis of 942 assessments from 868 children found children with genetic diagnoses scored >1 SD lower on Bayley cognitive, language, and motor indexes versus those without. After adjustment, cardiac diagnosis was significantly associated with cognitive and motor indexes, with dextro-transposition having the highest scores among groups. Other risk factors included lower birth weight, male sex, older age at initial surgery, and longer hospital stay. Clinical implication: implement routine early developmental surveillance for infants undergoing cardiac surgery, and prioritize genetic evaluation when delays are found.
