Imipenem and meropenem are the recommended antipseudomonal carbapenems for nosocomial pneumonia per clinical practice guidelines. However, these agents have a relatively broader spectrum of activity than other antibiotics and need to be reserved. Carbapenems might cause higher rate of superinfection. The aim of this study was to compare the rate of superinfection between patients who received imipenem or meropenem versus those who received non-carbapenem treatment. PubMed, EMBASE, Cochrane Library databases and two trial registries were searched for relevant randomized controlled trials of hospitalized adults with pneumonia through February 24, 2017 without date or language restrictions...

BACKGROUND: There is an urgent need to develop novel inhibitors against clinically widespread extended-spectrum β-lactamases (ESBLs) to meet the challenges of the ever-evolving threat of antibiotic resistances. Most existing ESBL inhibitors sharing a common chemical feature of β-lactam ring in their molecule, this structural characteristic makes them intrinsically susceptible to enzymatic breakdown by the resistance mechanisms employed by the bacteria. OBJECTIVE: The aim of this study was to screen and discover novel lead compounds by using L-proline as initial scaffold to create a "non-sulfur, non-β-lactam" new chemotypes for potential ESBL inhibitors...
