An informed advisor wishes to convey her valuable information to an uninformed decision maker with identical preferences. Thus she has a current incentive to truthfully reveal her information. But if the decision maker thinks that the advisor might be biased in favor of one decision and the advisor does not wish to be thought to be biased, the advisor has a reputational incentive to lie. If the...

Abstract Background In adults with C. difficile infection (CDI), higher baseline stool concentrations of toxins A and B are associated severe disease, CDI-attributable outcomes, recurrence. We evaluated whether toxin concentration predicts these presentations in children CDI. Methods performed a prospective cohort study from 2016-2019. Participants were inpatients ≤17 years old at two pediatric...

be critical to prevent attachment of pathogen. BF production increased or remained unchanged in the presence of amikacin. Due to toxicity concerns and variation in resistance patterns, minocycline is a viable treatment option against A. baumannii. Additional studies are warranted. Disclosures. K.

Abstract Background Several methods are used to account for various hospital characteristics when comparing antimicrobial use (AU) between heterogenous hospitals. Recently, a new stewardship metric that adjusts AU by microbiological burden (a-AU) of the bacteria was proposed (Figure 1). It accounts resistant phenotypes observed at given institution, allowing more balanced comparison across This...

Notice that this means if we change variables ( x′ y′ ) = v′ = Av (the entries of A are integers) then Q(x′, y′) = (Av) QAv = v (A QA)v. Therefore, if Q represents a number then so does A QA. In particular, if A has an inverse with integer entries, then we get that Q and A QA represent all the same numbers. Clearly if A has an inverse B with integer entries, then det A detB = det AB = 1, thus d...
