30-Second Takeaway
- High–delivery valved holding chambers meaningfully improved short‑term outcomes and hospitalization risk in young children with acute wheeze.
- Pediatric OHCA survival probability fell below 1% after about 15 minutes of EMS CPR, informing goals‑of‑care discussions.
- Simple in situ simulation partnerships substantially improved office‑based pediatric emergency preparedness and simulated care quality.
- Medicaid unwinding, viral LRTIs, diabetes trends, and environmental exposures highlight growing risks for already vulnerable pediatric populations.
- New neonatal tools and data address congenital anomaly detection and preterm infant outcomes, especially in resource‑limited or safety‑net settings.

New data on acute wheeze management, pediatric OHCA prognosis, outpatient preparedness, and emerging risks in vulnerable child populations
Higher–delivery valved holding chamber improves outcomes in young children with acute wheeze
In this 4‑center Finnish ED RCT, 80 children aged 6–48 months with moderate–severe acute wheeze received salbutamol via 2 different valved holding chambers (VHCs). The higher–delivery VHC produced substantially lower posttreatment RDAI scores and larger RDAI improvements than the lower‑delivery device. Hospitalization was less frequent with the higher–delivery VHC (20% vs 50%), with a number needed to treat of about 3. Children using the higher‑delivery chamber also had lower posttreatment respiratory rates, higher oxygen saturations, and needed fewer additional salbutamol doses.
Pediatric OHCA survival drops below 1% after about 15 minutes of EMS CPR
This North American cohort included 1,313 EMS‑treated, non‑traumatic pediatric out‑of‑hospital cardiac arrests from 2011–2015. Overall survival to hospital discharge was 10.4%, and 18.0% achieved prehospital ROSC, typically after about 10 minutes of CPR. Among children still receiving CPR at each minute, modeled survival probability fell from 7.9% at 1 minute to less than 1% at 14.8 minutes. The upper bound of the 95% CI for survival probability dropped below 1% at 22 minutes of EMS‑initiated CPR. These data provide time‑dependent estimates that can inform EMS termination‑of‑resuscitation protocols and real‑time counseling of families.
In situ simulation markedly improves pediatric emergency readiness in primary care offices
This multicenter prospective study partnered 21 pediatric primary care offices with academic centers to deliver an in situ simulation‑based preparedness intervention. Eighteen offices completed baseline and follow‑up preparedness assessments; 12 completed both emergency simulations. Median emergency preparedness checklist scores improved from 68% to 82%. Median performance in respiratory distress simulations rose from 50% to 82%, and seizure scenario performance improved from 42% to 85%. Results suggest that structured feedback and local academic collaboration can rapidly upgrade outpatient practices’ ability to manage acute pediatric emergencies.
Medicaid unwinding linked to sharp declines in pediatric preventive and mental health care
This national community‑health‑center EHR study followed 448,123 Medicaid‑insured children during the 2023 Medicaid coverage unwinding. Overall, 8.4% were disenrolled from Medicaid and became uninsured. Compared with continuously insured peers, disenrolled children had roughly 60% fewer preventive visits and substantially fewer evaluation and management visits. They also had fewer mental health encounters with both primary care clinicians and specialists. Age‑adjusted influenza vaccination coverage was lower in uninsured children (27.3%) than those retaining Medicaid (39.3%).
