Despite the improved outcome associated with current treatment strategies ofpediatric acute lymphoblastic leukemia (ALL), relapse still represents a major challenge. Pediatric ALL demonstrates branched evolution in response to selective pressure exerted by therapy; relapse founder clones emerge from pre-leukemic clones or minor subclones present at diagnosis. It is hence crucial to develop biomarkers capable of tracking subclones throughout therapy. Current practices for monitoring disease response in leukemia rely on the analysis of BM biopsy sample at specific time points throughout therapy. Not only the invasiveness of the BM biopsy hinders the sequential sampling, but also, the currently implied techniques are …

Rapid molecular technology can detect the mecA resistance gene in Staphylococcus aureus (SA), predicting methicillin susceptibility in under one hour. In combination with antimicrobial stewardship program interventions in adults with SA bacteremia, rapid mecA testing decreases time to targeted therapy. This intervention has not yet been shown effective in pediatric patients or in the absence of real-time stewardship interventions. The objective of this study was to determine if time to optimal therapy decreased following implementation of GeneXpert rapid diagnostic testing (RDT) in a pediatric institution without a formal antimicrobial stewardship protocol for response. The primary outcome was time to optimal …
