| ABSTRACT Background: The impact of central venous catheter (CVC) removal on the outcome of patients with candidemia is controversial, with studies reporting discrepant results depending on the time of CVC removal (early or any time during the course of candidemia). Objective: Evaluate the effect of time to CVC removal, early (within 48 h from the diagnosis of candidemia) vs. removal at any time during the course of candidemia, on the 30-day mortality. Methods: Retrospective cohort study of 285 patients with candidemia analyzing CVC removal within 48 h (first analysis) or at any time (second analysis). Results: A CVC was in place in 212 patients and was removed in 148 (69.8%), either early (88 patients, 41.5%) or late (60 patients, 28.3%). Overall, the... |

| OBJECTIVE: To investigate the pathogenesis of bloodstream infection by Staphylococcus epidermidis, using the molecular epidemiology, in high-risk neonates. METHODS: We conducted a prospective study of a cohort of neonates with bloodstream infection using central venous catheters for more than 24 h. "National Healthcare Safety Network" surveillance was conducted. Genotyping was performed by DNA fingerprinting and mecA genes and icaAD were detected by multiplex-PCR. RESULTS: From April 2006 to April 2008, the incidence of bloodstream infection and central venous catheter-associated bloodstream infection was 15.1 and 13.0/1000 catheter days, respectively, with S. epidermidis accounting for 42.9% of episodes. Molecular analysis was used to document the... |

| Central venous catheters from intensive care unit patients were subjected to microbiological methods (semiquantitative culture) and scanning electron microscopy in order to assess microbial attachment and correlate it with blood cultures. During the period of the survey, 59 patients with inserted central venous catheters were studied. The type of catheter used was nontunneled, noncuffed, single lumen, made of polyurethane. Blood samples for cultures were collected at the moment of catheter removal. Data on the patient's age, gender, catheter insertion site, and duration of catheterization were also obtained. From 63 catheters tips analysed, 30 (47.6%) showed microbial colonization. Infection proved to be more prevalent in 26 (41.3%) patients with catheters... |

| Biofilm bacterial infections are common in patients undergoing treatment with haemodialysis. This study involved 16 patients (7 males, 9 females; ages from 22 to 81 with an average age of 50) who had had a total of 25 temporary haemodialysis polyurethane catheter insertions into the subclavian vein (22 dual-lumen and 3 triple-lumen). The catheters remained in place from 3 to 91 days, on an average of 47 days. The reasons for catheter removal were: bad functioning (44%), suspicion of catheter-related infection (20%), availability of permanent access (16%), accidental removal (12%), signs and symptoms of infection at the site of catheter insertion (4%), and exogenous contamination (4%). Positive tip cultures were observed on seven of the catheters (28%),... |
