BACKGROUND: Colonized patients are a reservoir for transmission of multidrug-resistant organisms (MDROs). Not many studies have examined the effectiveness of daily chlorhexidine gluconate (CHG) bathing under routine care conditions. We present a descriptive analysis of the trends of MDRO colonization following implementation of daily CHG bathing under routine clinical conditions in an intensive care unit (ICU). METHODS: From May 2010-January 2011, we screened patients admitted to a 24-bed ICU for and methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and fluoroquinolone-resistant gram-negative bacilli (FQRGNB)...

Background Treatment of the injured from war zones with wounds with multi-resistant pathogens is becoming more common in Germany, especially in German Armed Forces Hospitals. In most cases, the pre-treatment of these patients has been inadequate and they have a high load of rare pathogens. In Germany, hospitals have to evaluate these pathogens by law. The aim of this study was to review current German guidelines and data on the array of pathogens of complex trauma wounds in Germany and to compare patients with wounds and multi-resistant pathogens from war zones treated in Germany...

Our strategy to combat resistant bacteria consisted in targeting the GyrB/ParE ATP-binding sites located on bacterial DNA gyrase and topoisomerase IV and not utilized by marketed antibiotics. Screening around the minimal ethyl urea binding motif led to the identification of isoquinoline ethyl urea 13 as promising starting point for fragment evolution. The optimization was guided by structure-based design and focused on antibacterial activity in vitro and in vivo, culminating in the discovery of unprecedented substituents able to interact with conserved residues within the ATP-binding site...

Vancomycin resistance is conferred upon vancomycin-resistant enterococci (VRE) through the replacement of peptidoglycan (PG) stem terminal d-Ala-d-Ala with d-Ala-d-Lac. The d-Ala-d-Lac incorporation can affect both the fitness and virulence of VRE. Here we comprehensively investigate the changes to PG composition in vancomycin-resistant Enterococcus faecalis following the growth in presence of vancomycin using liquid chromatography-mass spectrometry. Using high-resolution mass spectrometry, 104 unique muropeptides fragments were identified and the relative abundance of each fragment was accurately quantified by integrating the ion current of a selected ion using extracted-ion chromatogram...

 Drug-resistant bacteria including methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Pseudomonas aeruginosa, and vancomycin-resistant enterococci (VRE) have been spreading; however, the development of new antibacterial drugs has not progressed accordingly. Novel antibacterial drugs or their candidate seeds need to be developed for effective antibiotic therapy. Under these conditions, the search for novel compounds and novel targets is important. In Okayama University, as a part of the Drug Discovery for Intractable Infectious Diseases project, we are proceeding with the development of antibacterial drugs for the treatment of drug-resistant bacterial infections...

BACKGROUND: When a memory is recalled, it may again exist in a labile state and stored information becomes amenable to change, a psychobiological process known as reconsolidation. Exposure therapy for anxiety disorders involves accessing a fear memory and modifying it with less fearful information. A preclinical study reported that providing a reminder of a fear memory 10 min prior to extinction training in humans decreased fear up to 1 year later (Schiller et al., 2010). METHODS: For this pilot clinical study, we used virtual reality exposure therapy (VRE) for fear of flying (FoF) to determine if using a cue to reactivate the memory of the feared stimulus 10 min prior to exposure sessions leads to fewer anxiety-related behaviors and a more durable response compared to a neutral cue...
