BACKGROUND Ventilator-associated pneumonia (VAP) is the most frequent nosocomial infection in intensive care units (ICUs). Most published studies have analysed nurses' theoretical knowledge about a specific procedure; however, the transfer of this knowledge to the practice has received little attention. AIM To assess the impact of training session on nurses' knowledge regarding VAP, complianc...

The utility of procalcitonin levels to improve the accuracy of clinical and microbiological parameters in diagnosing ventilator-associated pneumonia (VAP) was evaluated. Sequential measurement of procalcitonin and C-reactive protein levels and the calculation of the simplified Clinical Pulmonary Infection Scores (CPIS) were performed in 44 patients mechanically-ventilated for >48 h with neither...

The vesicle-associated membrane protein-associated protein B (VAP-B) is a tail-anchored protein in the endoplasmic reticulum (ER). VAP-B functions as an adaptor protein to recruit target proteins to the ER and execute various cellular functions, lipid transport, membrane traffic, ER stress etc. Recently, VAP-B has been shown to regulate the nuclear envelope protein transport through the ER-Golg...

The purpose of the present study was to validate the quantitative culture and cellularity of bronchoalveolar lavage (BAL) for the diagnosis of ventilator-associated pneumonia (VAP). A prospective validation test trial was carried out between 1992 and 1997 in a general adult intensive care unit of a teaching hospital. Thirty-seven patients on mechanical ventilation with suspected VAP who died at...

Cell counts of leukocytes subpopulations are demonstrating to have an important value in predicting outcome in severe infections. We evaluated here the render of leukogram counts to predict outcome in patients with ventilator-associated pneumonia (VAP) caused by Staphylococcus aureus. Data from patients admitted to the ICU of Hospital Clínico Universitario de Valladolid from 2006 to 2011 with d...

We report a novel host-associated virulence plasmid in Rhodococcus equi, pVAPN, carried by bovine isolates of this facultative intracellular pathogenic actinomycete. Surprisingly, pVAPN is a 120-kb invertron-like linear replicon unrelated to the circular virulence plasmids associated with equine (pVAPA) and porcine (pVAPB variant) R. equi isolates. pVAPN is similar to the linear plasmid pNSL1 f...

Inflammatory leukocyte accumulation is a common feature of major ocular diseases, such as uveitis, diabetic retinopathy, and age-related macular degeneration. Vascular adhesion protein-1 (VAP-1), a cell surface and soluble molecule that possesses semicarbazide-sensitive amine oxidase (SSAO) activity, is involved in leukocyte recruitment. However, the expression of VAP-1 in the eye and its contr...

Background. A need exists for new antimicrobial agents to treat neonates, infants, and children for hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) caused by nosocomial antibiotic-resistant pathogens. Current and clear guidance on approval of new agents for all pediatric age groups is lacking. Methods. Studies on HAP and VAP in the neonatal and pediatric age groups w...

Polymorphonuclear leukocytes (PMNs) migrate from the blood into areas of inflammation by binding to the endothelial cells of blood vessels via adhesion molecules. Vascular adhesion protein-1 (VAP-1) is one of the molecules mediating leukocyte–endothelial cell interactions. It is also an endothelial cell–surface enzyme (amine oxidase) that produces reactive oxygen species during the catalytic re...

Hemodilution is one of the sequelae of cardiopulmonary bypass (CPB). Autologous blood priming (retrograde autologous priming [RAP]/venous antegrade priming [VAP]) and acute normovolemic hemodilution (ANH) may be effective techniques to minimize hemodilution. The primary objective of this study is to investigate the impact of RAP/VAP combined with ANH on changes in cerebral saturations. A retros...
