Purpose: The "out-of-hours effect," which indicates hospital admittance during weekends or nighttime, has poorer outcomes for patients than for those admitted on weekdays and is widely documented in various medical conditions. However, this effect remains understudied in pediatric trauma cases, including blunt liver and spleen injuries (BLSIs).
Methods: This was a secondary analysis of a nationwide multicenter retrospective study, focusing on pediatric patients with trauma (≤ 16 years old) with BLSI admitted from 2008 to 2019.
Objectives: Hemorrhagic events are a rare but potentially fatal complication in patients with polycythemia vera (PV).
Methods: We analyzed the characteristics of hemorrhagic events in 267 patients with PV.
Results: A median follow-up of 4.
