At admission (day 1), severity of illness was evaluated using the pediatric index of mortality 2 (PIM2) [20].
A descriptive, exploratory, quantitative design was used to explore student worry using the Pediatric Student Comfort and Worry Assessment Tool.
Clinical severity was assessed using the pediatric index of mortality 2 (PIM2) [ 12], pediatric risk of mortality (PRISM) score [ 13], and pediatric logistic organ dysfunction (PELOD) scale [ 14].
Zappitelli and colleagues also addressed the same issue in a pediatric population, using the modified pediatric RIFLE classification [ 18].
In order to classify CD in terms of its characteristics and severity, we used the Paris classification (a pediatric modification of the Montreal classification of IBD) [ 8] and the Pediatric Crohn's Disease Activity Index [ 9].
The whole body images were analyzed using pediatric software (Pediatric whole body uses QDR for Windows® 98 System, Guide Hologic Inc. 35. Bedford, MA, USA).
The modification of CNT using the plasma is presented in "Plasma Modification of CNTs".
ARDS was defined using the Berlin Criteria (1) and Pediatric ARDS PALICC criteria (2).
These values were subsequently used in the pediatric simulations.
Growth parameters were evaluated using the ABase software and North American pediatric reference values [19].
