High prevalence of colistin heteroresistance in specific species and lineages of Enterobacter cloacae complex derived from human clinical specimens.

Background: Colistin (CST) is a last-line drug for multidrug-resistant Gram-negative bacterial infections. CST-heteroresistant Enterobacter cloacae complex (ECC) has been isolated. However, integrated analysis of epidemiology and resistance mechanisms based on the complete ECC species identification has not been performed.

Selective Detection of DNA from Viable Mycobacterium tuberculosis Complex Strains Using the EMA-PCR Method.

In this study, the ability to discriminate viable from dead cells of Mycobacterium tuberculosis complex (MTC), using an ethidium monoazide (EMA) treatment-dependent viable bacteria selection PCR kit was examined. Detection of dead bacteria was possible for bacterial concentrations in the range 1.5 × 10-3.

Risk Factors for Postoperative Delirium in Abdominal Surgery: A Proposal of a Postoperative Delirium Risk Score in Abdominal Surgery.

Background/aims: Despite the presence of several diagnosis scales for delirium, no prediction scale that is specific for postoperative delirium after abdominal surgery is available. We sought to create a novel delirium prediction system that is specific for abdominal surgery.

Methods: This study included 213 consecutive patients who required management in the surgical ICU following abdominal surgery.
