Comparison of a novel biodegradable polymer sirolimus-eluting stent With a durable polymer everolimus-eluting stent results of the randomized BIOFLOW-II trial

Windecker, Stephan ; Haude, Michael ; Neumann, Franz-Josef ; Stangl, karl ; Witzenbichler, Bernhard ; Slagboom, Ton ; Sabaté, Manel ; Goicolea, Javier ; Barragan, Paul ; Cook, Stéphane ; Piot, Christophe ; Richardt, Gert ; Merkely, Béla ; Schneider, Henrik ; Bilger, Johannes ; Erne, Paul ; Waksman, Ron ; Zaugg, Serge ; Jüni, Peter ; Lefèvre, Thierry

In: Circulation: Cardiovascular Interventions, 2015, vol. 8, no. 2, p. e001441

Background—Biodegradable polymers for release of antiproliferative drugs from drug-eluting stents aim to improve vascular healing. We assessed noninferiority of a novel ultrathin strut drug-eluting stent releasing sirolimus from a biodegradable polymer (Orsiro, O-SES) compared with the durable polymer Xience Prime everolimus-eluting stent (X-EES) in terms of the primary end...

Multiple colonization with highly resistant bacteria: carbapenemase-producing Enterobacteriaceae, carbapenemase-producing Pseudomonas aeruginosa, carbapenemase-producing Acinetobacter baumannii, and glycopeptide-resistant Enterococcus faecium

Girlich, Delphine ; Nordmann, Patrice ; Lécuyer, Hervé ; Berche, Patrick ; Marmorat-Khuong, Anne ; Gros, Isabelle ; Cuzon, Gaëlle ; Dortet, Laurent

In: Diagnostic Microbiology and Infectious Disease, 2015, p. -

The dissemination of carbapenemase-producing bacteria worldwide is an important source of concern because carbapenemase producers are multidrug resistant (Nordmann and Poirel, 2014). National guidelines increasingly recommend a systematic screening of at least carbapenemase-producing Enterobacteriaceae (CPE) and glycopeptide-resistant enterococci (GRE) in patients admitted to hospitals who have...

In vitro prediction of the evolution of the GES-1 β-lactamase hydrolytic activity

Bontron, Séverine ; Poirel, Laurent ; Nordmann, Patrice

In: Antimicrobial Agents and Chemotherapy, 2015, p. AAC.04450–14

Resistance to ß-lactams is constantly increasing, due to the emergence of totally new enzymes, but also to the evolution of pre-existing ß-lactamases. GES-1 is a clinically-relevant extended-spectrum β-lactamase (ESBL) hydrolyzing penicillins and broad-spectrum cephalosporins, but sparing monobactams and carbapenems. However, several GES-1 variants (i.e. GES-2 and GES-5) previously identified...

The choice of statistical methods for comparisons of dosimetric data in radiotherapy

Chaikh, Abdulhamid ; Giraud, Jean-Yves ; Perrin, Emmanuel ; Bresciani, Jean-Pierre ; Balosso, Jacques

In: Radiation Oncology, 2014, vol. 9, no. 1, p. 205

Purpose: Novel irradiation techniques are continuously introduced in radiotherapy to optimize the accuracy, the security and the clinical outcome of treatments. These changes could raise the question of discontinuity in dosimetric presentation and the subsequent need for practice adjustments in case of significant modifications. This study proposes a comprehensive approach to compare different...

IncH-type plasmid harboring the blaCTX-M-15, blaDHA-1, and qnrB4 genes recovered from animal isolates

Schlüter, Andreas ; Nordmann, Patrice ; Bonnin, Rémy A. ; Millemann, Yves ; Eikmeyer, Felix G. ; Wibberg, Daniel ; Pühler, Alfred ; Poirel, Laurent

In: Antimicrobial Agents and Chemotherapy, 2014, p. AAC.02695–14

The whole sequence of plasmid pENVA carrying the extended-spectrum ß-lactamase gene blaCTX-M-15 was determined. It has been identified from a series of clonally-related Klebsiella pneumoniae ST274 strains recovered from companion animals. This plasmid was 253,984-bp in-size and harbored, in addition to blaCTX-M-15, a large array of genes encoding...

Worldwide dissemination of the NDM-type carbapenemases in gram-negative bacteria

Dortet, Laurent ; Poirel, Laurent ; Nordmann, Patrice

In: BioMed Research International, 2014, vol. 2014, p. e249856

The emergence of one of the most recently described carbapenemases, namely, the New Delhi metallo-lactamase (NDM-1), constitutes a critical and growingly important medical issue. This resistance trait compromises the efficacy of almost all lactams (except aztreonam), including the last resort carbapenems. Therapeutical options may remain limited mostly to colistin, tigecycline, and fosfomycin....

Spread of NDM-1-producing Enterobacteriaceae in a neonatal intensive care unit in Istanbul, Turkey

Poirel, Laurent ; Yilmaz, Mesut ; Istanbullu, Ayse ; Arslan, Ferhat ; Mert, Ali ; Bernabeu, Sandrine ; Nordmann, Patrice

In: Antimicrobial Agents and Chemotherapy, 2014, vol. 58, no. 5, p. 2929–2933

Twenty-two consecutive carbapenem-resistant enterobacterial isolates were recovered from patients hospitalized between January and April 2013 in different units at a university hospital in Istanbul, Turkey. These were Klebsiella pneumoniae isolates producing the carbapenemases OXA-48, NDM-1, and KPC-2, Enterobacter cloacae isolates producing NDM-1, and Escherichia coli isolates producing OXA-48....
