Parenteral beta-blocker therapy via continuous infusion has shown promising results for improved outcomes for patients with septic shock. As patients with septic shock may require multiple intravenous medications, compatibility is necessary to co-infuse these medications through a y-site connector. The purpose of this study was to examine the physical compatibility of select intravenous drugs used for patients with septic shock combined with various intravenous beta-blockers including esmolol, labetalol, and metoprolol through a simulated y-site infusion...

Gram-negative bacteria (GNBs) are common pathogens causing severe sepsis. Rapid evaluation of drug susceptibility would guide effective antibiotic treatment, and promote life-saving. A total of 78 clinical isolates of 13 gram-negative species collected between April 2013 and November 2013 from two medical centers in Tainan were tested. Bacterial morphology changes in different concentrations of antibiotics were observed under the electric field of a quadruple electrode array using light microscopy. The minimal inhibitory concentrations (MICs) of four antimicrobial agents, namely cefazolin, ceftazidime, cefepime, and doripenem, were determined by the dielectrophoretic antimicrobial susceptibility testing (dAST) and by the conventional broth dilution testing (BDT)...

OXA-51 is a class D β-lactamase that is thought to be the native carbapenemase of Acinetobacter baumannii. Many variants of OXA-51 containing active site substitutions have been identified from A. baumannii isolates, and some of these substitutions increase hydrolytic activity toward carbapenem antibiotics. We have determined the high-resolution structures of apo OXA-51 and OXA-51 with one such substitution (I129L) with the carbapenem doripenem trapped in the active site as an acyl-intermediate. The structure shows that acyl-doripenem adopts an orientation very similar to carbapenem ligands observed in the active site of OXA-24/40 (doripenem) and OXA-23 (meropenem)...
