The accurate phenotypic detection of Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae is an increasing necessity worldwide. We evaluated the performance of boronic acid combined-disk tests using as substrate imipenem or meropenem and as inhibitor of KPC production 300 μg aminophenylboronic acid (APBA), 600 μg APBA, or 400 μg phenylboronic acid (PBA). Tests were considered ...

BACKGROUND The emergence of bla(KPC)-containing Klebsiella pneumoniae (KPC-Kp) isolates is attracting significant attention. Outbreaks in the Eastern USA have created serious treatment and infection control problems. A comparative multi-institutional analysis of these strains has not yet been performed. METHODS We analysed 42 KPC-Kp recovered during 2006-07 from five institutions located in t...

The purpose of this paper is to compute of fundamental relations of hypergroups. In this regards first we study some basic properties of fundamental relation of hypergroups, then we show that any given group is isomorphic to the fundamental group of a nontrivial hypergroup. Finally we study the connections between categories of hypergroups and groups via the fundam...

OBJECTIVE To determine the effect of a bundle of infection control interventions on the horizontal transmission of Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae during an outbreak. DESIGN Quasi-experimental study. Setting. Long-term acute care hospital. Intervention. On July 23, 2008, a bundled intervention was implemented: daily 2% chlorhexidine gluconate baths for patien...

PURPOSE In a primary care context favoring group practices, we assessed the validity of 2 new continuity measures (both versions of known provider continuity, KPC) that capture the concentration of care over time from multiple physicians (multiple provider continuity, KPC-MP) or from the physician seen most often (personal provider continuity, KPC-PP). METHODS Patients with diabetes or cardio...

Pseudomonas aeruginosa strain 10265 was recovered from a patient with pneumonia in a Chinese public hospital, and it displays the carbapenem resistance phenotype due to the acquisition of a non-conjugative but mobilizable IncP-6-type plasmid p10265-KPC. p10265-KPC carries a Tn5563-borne defective mer locus, and a novel ΔISEc33-associated bla KPC-2 gene cluster without paired inverted repeats an...

Currently available data on the field of velocities Vr, Vl, Vb for open star clusters are used to perform a kinematic analysis of various samples that differ by heliocentric distance, age, and membership in individual structures (the Orion, Carina–Sagittarius, and Perseus arms). Based on 375 clusters located within 5 kpc of the Sun with ages up to 1 Gyr, we have determined the Galactic rotation...

The NucliSENS EasyQ KPC assay (bioMérieux SA, Marcy l'Etoile, France) was compared with a routinely used phenotypic method for detection of Enterobacteriaceae producing Klebsiella pneumoniae carbapenemase (KPC)-type carbapenemases, using 806 stool samples and rectal swabs. Compared with the phenotypic method, the EasyQ KPC assay had a sensitivity and specificity of 93.3% and 99.0%, respectively...

Group recommendation aims to recommend items a group of users. In this work, we study in particular scenario, namely occasional recommendation, where groups are formed ad hoc and users may just constitute for the first time—that is, historical group-item interaction records highly limited. Most state-of-the-art works have addressed challenge by aggregating members’ personal preferences learn re...

We present a unified rotation curve of the Galaxy re-constructed from the existing data by re-calculating the distances and velocities for a set of galactic constants R0 =8 kpc and V0 =200 km s . We decompose it into a bulge with de Vaucouleurs-law profile of half-mass scale radius 0.5 kpc and mass 1.8×10M⊙, an exponential disk of scale radius 3.5 kpc of 6.5× 10M⊙, and an isothermal dark halo o...
