Clinical and Microbiological Analysis of Risk Factors for Mortality in Patients With Carbapenem-Resistant Bacteremia.

Background: Carbapenem-resistant (CRAB) infection is associated with significant mortality, causing worldwide concern, yet there are limited data on contributing microbiological factors. This study aimed to identify the clinical and microbiologic risk factors for mortality in CRAB bacteremia.

Methods: Adult patients with monomicrobial CRAB bacteremia in a 2700-bed tertiary hospital between December 2012 and December 2018 were retrospectively enrolled.

Utility of Magnetic Resonance Imaging for Differentiating Necrotizing Fasciitis from Severe Cellulitis: A Magnetic Resonance Indicator for Necrotizing Fasciitis (MRINEC) Algorithm.

We developed a new magnetic resonance indicator for necrotizing fasciitis (MRINEC) algorithm for differentiating necrotizing fasciitis (NF) from severe cellulitis (SC). All adults with suspected NF between 2010 and 2018 in a tertiary hospital in South Korea were enrolled. Sixty-one patients were diagnosed with NF and 28 with SC.

Changes in the early mortality of adult patients with carbapenem-resistant Acinetobacter baumannii bacteremia during 11 years at an academic medical center.

Background: In the past decade, carbapenem-resistant Acinetobacter baumannii (CRAB) has emerged as a major pathogen of serious infections in critically ill adult patients. Despite very limited antimicrobial options, clinicians have sought to reduce the mortality of patients with serious CRAB infections. To determine whether these long-term efforts effectively lessened the mortality of such patients, we investigated changes in the early mortality of adult patients with CRAB bacteremia and related clinical factors.

Usefulness of national respiratory virus surveillance data for clinicians who manage adult patients.

The Korean Centers for Disease Control and Prevention (KCDC) provides weekly respiratory virus (RV) surveillance reports on its website (the KCDC data). Clinicians in clinical settings wherein the use of PCR for RVs is not a routine laboratory test for adult patients with acute respiratory illness (ARI) may question the clinical utility of such a national RV surveillance dataset in predicting RV outbreaks among their adult patients. We compared the KCDC data to the RV PCR data of adult patients who visited a tertiary care center.
