Risk stratification of emergency department (ED) patients with upper gastrointestinal bleeding (UGIB) using preendoscopic risk scores can aid ED physicians in disposition decision-making. We conducted a systematic review to assess the predictive value of preendoscopic risk scores for 30-day serious adverse events. ⋯ The GBS with a cutoff point of 0 was superior over other cutoff points and risk scores for identifying low-risk patients but had a very low specificity. None of the risk scores identified by our systematic review were robust and, hence, cannot be recommended for use in clinical practice. Future prospective studies are needed to develop robust new scores for use in ED patients with UGIB.

Multicenter Study Observational Study
The Influence of Age on the Diagnostic Performance of White Blood Cell Count and Absolute Neutrophil Count in Suspected Pediatric Appendicitis.
White blood cell (WBC) count and absolute neutrophil count (ANC) are a standard part of the evaluation of suspected appendicitis. Specific threshold values are utilized in clinical pathways, but the discriminatory value of WBC count and ANC may vary by age. The objective of this study was to investigate whether the diagnostic value of WBC count and ANC varies across age groups and whether diagnostic thresholds should be age-adjusted. ⋯ WBC count and ANC had better diagnostic performance with increasing age. Age-adjusted values of WBC count or ANC should be considered in diagnostic strategies for suspected pediatric appendicitis.
