Serotype 3 is one of the most often detected pneumococcal serotypes in adults and it is associated with serious disease. In contrast, the isolation of serotype 3 by bacterial culture is unusual in children with invasive pneumococcal disease (IPD). The purpose of this study was to learn the serotype distribution of IPD, including culture-negative episodes,(More)
Traditionally, invasiveness indexes have been based on culture methods. We aimed to establish a new classification of the invasive disease potential of pneumococcal serotypes causing invasive pediatric disease in the era of conjugate vaccines in Catalonia, Spain, by adding capsular typing of Streptococcus pneumoniae in direct sample. Two samples of children(More)
The problem of finding the Euclidean distance between two convex polyhedra can be reduced to the combinatorial optimization problem of finding the minimum distance between their faces. This paper presents a global optimality criterion for this problem. An algorithm (QLDPA) for the fast computation of the distance between convex and bounded polyhedra is(More)
Point of care (POC) laboratory testing is used to improve emergency department (ED) throughput but often overuses resources by duplicating formal laboratory testing. This study sought to evaluate the effect of a multimodal intervention on duplicate chemistry testing. This pre-post analysis included all visits to 2 urban EDs between June 2014 and June 2016.(More)
