The importance of viruses in ventilator-associated pneumonia.

Objective: Ventilator-associated pneumonia (VAP) remains a challenge. The importance of viruses in VAP is not established. We sought to determine the prevalence of viruses in VAP and the outcomes of viral VAP.

Spectrum scores: Toward a better definition of de-escalation.

Spectrum scores measure antimicrobial utilization while also quantifying the spectrum of activity. Accordingly, changes in spectrum score can be used to identify antimicrobial de-escalation. We show that spectrum-score-based de-escalation has a 95.

Impact of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers on Renal Function in Type 1 Cardiorenal Syndrome.

Introduction: Angiotensin-converting enzyme inhibitor (ACE-I) and angiotensin receptor blocker (ARB) discontinuation during acute heart failure (AHF) is associated with increased mortality following hospitalization. Although the etiology of acute kidney injury (AKI) in type 1 cardiorenal syndrome (CRS) has been linked to renal venous congestion, ACE-I/ARB withdrawal (AW) theoretically promotes renal function recovery. ACE-I/ARBs are dose-reduced or withheld in approximately half of patients with CRS, but the subsequent impact on renal function remains largely uninvestigated.
