BACKGROUND: Microorganisms can intraluminally access a central venous catheter via the catheter hub. The catheter hub should be appropriately disinfected to prevent central line-associated bloodstream infections (CLABSIs). However, compliance with the time-consuming manual disinfection process is low. An alternative is the use of an antiseptic barrier cap, which cleans the catheter hub by continuous passive disinfection. OBJECTIVE: To compare the effects of antiseptic barrier cap use and manual disinfection on the incidence of CLABSIs...

Survival rates of preterm infants have improved in the past few decades, and central venous catheters play an important role in the intensive medical treatment of these neonates. Unfortunately, these indwelling catheters increase the risk of intracardiac thrombosis, and they provide a nidus for microorganisms during the course of septicemia. Herein, we report a case of persistent bacteremia due to methicillin-resistant Staphylococcus aureus in an extremely low birth weight (ELBW) infant, along with vegetation observed on an echocardiogram, the findings which are compatible with a diagnosis of endocarditis...

BACKGROUND: Culture of catheter hubs and skin surrounding the catheter entry site has a negative predictive value for catheter tip colonization. However, manipulation of the hub for culture requires the hubs to be swabbed, introducing potential dislodging of biofilm and subsequent migration of microorganisms. Hubs are usually closed with needleless connectors (NCs), which are replaced regularly. Our objective was to evaluate whether culture of flushed withdrawn NCs is an alternative to hub culture when investigating central venous catheter colonization...

The rate of central venous catheter (CVC) use for patients on hemodialysis in the United States has decreased in recent years, though the rate of hospitalizations due to infections has increased. Each time a CVC hub is accessed, there is potential for microorganisms to enter the lumen and initiate a bloodstream infection. Needle-free catheter connectors provide a mechanically closed space to preventfrequent manipulation of catheter hubs. The needle-free connector may be a valuable addition to incorporate into infection prevention policies for hemodialysis units...
