Many serious bacterial infections are antibiotic-refractory due to biofilm formation. A key structural component of biofilm is extracellular DNA which is stabilized by bacterial proteins, including those from the DNABII family. TRL1068 is a high affinity human monoclonal antibody against a DNABII epitope conserved across both gram-positive and gram-negative bacterial species. In the current study, the efficacy of TRL1068 for disruption of biofilm was demonstrated in vitro in the absence of antibiotics by scanning electron microscopy...

External ventricular drainage is the most common procedure performed in daily neurosurgical practice. One devastating complication is ventriculostomy-associated infection, but the establishment of evidence-based management guidelines has been hindered by the lack of an universal definition. There is also limited data with regard to the utility of comorbidity health indices and surgery-related factors in predicting infection. This study aims to compare the incidence of infection according to five commonly used definitions and to identify risk factors for this complication...

BACKGROUND: Transthoracic intracardiac catheters are frequently inserted in children during congenital heart surgery for monitoring and vascular access purposes. Their use entails a small potential risk. AIM: We aimed to evaluate both catheter-associated morbidities related to maintenance and removal of transthoracic intracardiac catheters in pediatric cardiac patients, and predictors for catheter-associated adverse events. METHODS: Single-center retrospective cohort study of prospectively collected data of children aged 0-14 years receiving a transthoracic intracardiac catheter inserted in the operating room during 7 consecutive years at the University Children's Hospital Zurich...

BACKGROUND: Pneumococcal shunt infection is a rare event. There is no consensus on the therapeutic management of this kind of shunt infection according to literature reviews, and it seems to be different from infection with Staphylococcus epidermidis. We studied 2 shunted patients with pneumococcal meningitis, both of whom were treated with only antibiotics. The management of these cases seems to be different from that of shunt catheter infection due to these bacteria. We conducted a laboratory study to show the different behavior of pneumococcus compared to S...

Candida albicans is a commensal organism, commonly inhabiting mucosal surfaces of healthy individuals, as a part of the resident microbiota. However, in susceptible hosts, especially hospitalized and/or immunocompromised patients, it may cause a wide range of infections. The presence of abiotic substrates, such as central venous or urinary catheters, provides an additional niche for Candida attachment and persistence, particularly via biofilm development. Furthermore, Candida biofilm is poorly susceptible to most antifungals, including azoles...

Staphylococcus aureus is a common pathogen isolated from burn patients that can form biofilms on burn wounds and implanted deep vein catheters, which often leads to refractory infections or even biofilm-related sepsis. As biofilm formation is usually regulated by environmental conditions, we hypothesized that serum composition may be altered after burn injury, potentially affecting the ability of infecting bacteria to form biofilms. As predicted, we observed that serum from burn-injured rats increases biofilm formation by S...

REVIEW
Taison Bell, Naomi P O'Grady
Central venous catheters (CVCs) are commonly used in critically ill patients and offer several advantages to peripheral intravenous access. However, indwelling CVCs have the potential to lead to blood stream infections, with the risk increasing with an array of characteristics such as catheter choice, catheter location, insertion technique, and catheter maintenance. Evidence-based guidelines have led to a significant reduction in the incidence of blood stream infections associated with CVCs. The combination of guideline implementation and newer technologies has the potential to further reduce morbidity and mortality from infections related to CVCs...

BACKGROUND: Central venous catheter-related infections (CVCIs) in patients on maintenance hemodialysis (HD) have been documented due to unsafe/unsterile manipulations by nurses during HD machine deconnection and reconnection. Given the gravity of CVCIs in HD patients using catheter access, precise, safe installation of the device, and good nursing technique are crucial. AIM: To assess and compare safety performance and complications of a Y-connection (n=133) versus the usual tunneled central venous catheter (CVC) technique (n=73) among HD patients and then explore preferences between techniques among patients and frontline HD nurses...

BACKGROUND: Patients starting dialysis often have substantial residual kidney function. Incremental hemodialysis provides a hemodialysis prescription that supplements patients' residual kidney function while maintaining total (residual + dialysis) urea clearance (standard Kt/Vurea) targets. We describe our experience with incremental hemodialysis in patients using NxStage System One for home hemodialysis. CASE PRESENTATION: From 2011 to 2015, we initiated 5 incident hemodialysis patients on an incremental home hemodialysis regimen...

BACKGROUND: Peripherally inserted central catheters (PICCs) provide enormous benefit to patients. However, recent publications have highlighted relatively high PICC-associated complication rates. We report on patient and device outcomes from a nurse-led program. METHODS: We performed a retrospective analysis of a prospective cohort of consecutive patients undergoing PICC insertion at The Ottawa Hospital between Jan. 1, 2013 and Dec. 31, 2014. Of the 8314 BioFlo PASV PICCs inserted, we randomly selected a sample of 700 and obtained a complete data set for 656...

Biofilm bacteria in the Tenckhoff catheter are notoriously difficult to eradicate. They are the potential sources of relapsing or repeat peritonitis among peritoneal dialysis (PD) patients. Inadequate penetration into biofilms by standard intraperitoneal antibiotics, as well as a lack of effective adjunctive treatment, leads to a high rate of Tenckhoff catheter loss as a result of biofilm bacteria. In hemodialysis, on the other hand, catheter-related bloodstream infection caused by biofilm bacteria does not necessarily lead to a loss of catheter...

We report the case of a catheter-related bloodstream infection caused by Chryseobacterium indologenes, an uncommon and multi-resistant pathogen, in a pediatric patient with a long-term vascular access device placed for chemotherapy treatment. The infection was successfully treated with ciprofloxacin antibiotic-lock therapy. This is the first report on successful salvage of a long-term device colonized by multi-resistant Chryseobacterium indologenes.
