Multicenter Study Comparative Study Observational Study
Procalcitonin as a Marker of Serious Bacterial Infections in Febrile Children Younger Than 3 Years Old.
There is no perfectly sensitive or specific test for identifying young, febrile infants and children with occult serious bacterial infections (SBIs). Studies of procalcitonin (PCT), a 116-amino-acid precursor of the hormone calcitonin, have demonstrated its potential as an acute-phase biomarker for SBI. The objective of this study was to compare performance of serum PCT with traditional screening tests for detecting SBIs in young febrile infants and children. ⋯ Procalcitonin is a more accurate biomarker than traditional screening tests for identifying young febrile infants and children with serious SBIs. Further study on a larger cohort of young febrile children is required to definitively determine the benefit of PCT over traditional laboratory screening tests for SBIs.

Does Numeracy Correlate With Measures of Health Literacy in the Emergency Department?
The objective was to quantify the correlation between general numeracy and health literacy in an emergency department (ED) setting. ⋯ Correlations between measures of general numeracy and measures of health literacy are in the low to moderate range. Performance on numeracy testing was nearly universally poor, even among patients performing well on health literacy screens, with a substantial proportion of the latter patients unable to answer half of the numeracy items correctly. Insofar as numeracy is considered a subset of health literacy, these results suggest that commonly used health literacy screening tools in ED-based studies inadequately evaluate and overestimate numeracy. This suggests the potential need for separate numeracy screening when these skills are important for health outcomes of interest. Providers should be sensitive to potential numeracy deficits among those who may otherwise have normal health literacy.
