Using Dog Scent Detection as a Point-of-Care Tool to Identify Toxigenic in Stool.

We evaluated the operating characteristics of 2 comparably trained dogs as a "point-of-care" diagnostic tool to detect toxin gene-positive . Although each dog could detect toxin gene-positive in stool specimens with sensitivities of 77.6 and 92.

Impact of two-step urine culture ordering in the emergency department: a time series analysis.

Background: Despite evidence against the use of antimicrobials for asymptomatic bacteriuria (ASB), they are frequently prescribed leading to unnecessary adverse events. Prior studies have shown that reducing unnecessary urine cultures (UCs) results in decreased antimicrobial utilisation for ASB. Emergency departments (EDs) submit the largest volume of UCs, yet efforts to limit overordering in this patient setting have had limited success.
