There is a controversy as to whether the number of lumens in the central venous catheters may impact the incidence of catheter-related bloodstream infection. We performed a systematic search (MEDLINE, PREMEDLINE, Cochrane Library, EMBASE, BIOSIS Previews, CINAHL, HealthSTAR/Ovid healthstar, bibliographies, any language, to April, 2003) for full reports on randomized comparisons of single-lumen ...
BACKGROUND AND PURPOSE Central venous catheter (CVC) infection is a common problem during hospitalization and nosocomial bloodstream infection in these patients is associated with increased morbidity, mortality, and health care cost. This prospective study examined the risk factors of CVC-related infections. METHODS During a 6-month period, a total of 281 patients who underwent central venous...
Nontyphoidal salmonellae (NTS) are important causes of community-acquired bloodstream infection. We describe patterns of antimicrobial resistance among invasive NTS in the United States. We compared bloodstream NTS isolates with those from stool submitted to the National Antimicrobial Resistance Monitoring System (NARMS) from 1996 to 2007. We describe antimicrobial resistance among invasive str...
In the mammalian bloodstream, African trypanosomes express the variant surface glycoprotein (VSG), continual switching of which allows evasion of the host immune response. Bloodstream VSG genes are transcribed from polycistronic bloodstream expression sites with promoters which are located 45-60 kb upstream. These promoters are not exclusively stage-regulated, being active in the insect midgut ...
This prospective case-control study was conducted from October 2003 to June 2007 to evaluate risk factors for multidrug resistance among extended-spectrum-b-lactamase-producing Escherichia coli and Klebsiella spp. (ESBL-EK) isolates in blood cultures. All adult patients (>18 years old) whose blood cultures grew ESBL-EK during the study period were included. An ESBL-EK isolate was defined as MDR...
BACKGROUND Nurse-physician collaboration may be related to outcomes in health care-associated infections. OBJECTIVE To examine the relationship between nurse-physician collaboration and health care-associated infections in critically ill adults. METHODS A secondary analysis was done of 5 years of nurses' perception data from 671 surveys from 4 intensive care units. Ventilator-associated pneum...
In nearly all eukaryotes, cellular differentiation is governed by changes in transcription, and stabilized by chromatin and DNA modification. Gene expression control in the pathogen Trypanosoma brucei, in contrast, relies almost exclusively on post-transcriptional mechanisms, so RNA binding proteins must assume the burden that is usually borne by transcription factors. T. brucei multiply in the...
Two MOB1 genes, MOB1-A and MOB1-B, were identified in Trypanosoma brucei. MOB1-A of T. brucei was shown to form a complex with TbPK50, a functional homologue of the Schizosaccharomyces pombe protein kinase Orb6, and immune precipitated MOB1-A exhibited histone H1 protein kinase activity. MOB1-A and TbPK50 were also shown to bind p12cks1, a cyclin-dependent kinase accessory protein. Immune fluor...
BACKGROUND Candida parapsilosis is increasingly responsible for invasive candidiasis in neonates. This study investigates phenotypic and genotypic features of C. parapsilosis microbial isolates and underlying clinical conditions associated with acquisition of C. parapsilosis in a neonatal intensive care unit (NICU) in Italy. METHODS Identification of C. parapsilosis was performed by VITEK® 2 ...
OBJECTIVES To compare the safety of a conventional polyurethane transparent dressing and a novel highly permeable polyurethane dressing, as compared with standard gauze and tape, as site dressings for pulmonary artery catheters; and to rigorously determine the sources of bloodstream infections deriving from these catheters. DESIGN Prospective, randomized, clinical trial. SETTING General adu...
