We have shown previously that increased extracellular osmolality stimulates expression and promoter activity of the type A natriuretic peptide receptor (NPR-A) gene in rat inner medullary collecting duct (IMCD) cells through a mechanism that involves activation of p38 mitogen-activated protein kinase (MAPK). The serum and glucocorticoid inducible kinase(More)
In a comparison of 3 agar plate methods, we found that a novel chromogenic medium, Remel Spectra™ CRE, had the best overall sensitivity (97.8%) when compared to the CHROMagar™ KPC (76.6%) and a direct ertapenem disk method (83.0%) for the detection of blaKPC-positive Enterobacteriaceae from perirectal swabs.
BACKGROUND Vancomycin troughs of 15-20 mg/L are recommended in the treatment of invasive staphylococcal disease, higher levels than previously recommended. OBJECTIVE/SETTING We sought to determine if there was an association between vancomycin trough and nephrotoxicity, defined as 0.5 mg/L or 50% increase in serum creatinine, at a large Veterans Affairs(More)
OBJECTIVE To determine whether transfer from a long-term care facility (LTCF) is a risk factor for colonization with Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae upon acute care hospital admission. DESIGN Microbiologic survey and nested case-control study. SETTING Four hospitals in a metropolitan area (Chicago) with an early(More)
PURPOSE OF REVIEW Antimicrobial resistance and a paucity of new antimicrobial agents are ongoing challenges. This review focuses on the major epidemiologic trends and novel treatments, when available, for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococcus, Clostridium difficile, and multidrug-resistant Gram-negative(More)
OBJECTIVE To determine anatomic sites of colonization in patients and to assess environmental contamination with Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae. DESIGN, SETTING, AND PATIENTS We conducted a cross-sectional microbiologic survey of 33 patients and their environments at 6 long-term acute care hospitals (LTACHs) in(More)
OBJECTIVE To identify the source of a pseudo-outbreak of Mycobacterium gordonae DESIGN Outbreak investigation. SETTING University Hospital in Chicago, Ilinois. PATIENTS Hospital patients with M. gordonae-positive clinical cultures. METHODS An increase in isolation of M. gordonae from clinical cultures was noted immediately following the opening of a newly(More)
BACKGROUND Recent exposure to health care facilities is a risk factor for carriage of multidrug-resistant organisms, but identification of hospitalized patients admitted from other health care facilities is often inefficient. METHODS At an acute care hospital, we utilized a standard point of origin code from a universal billing form (UB-04) to categorize(More)
