Background. Approximately 15-25% of hospitalized patients receive a urinary catheter during their hospital stay. Among UTIs acquired in the hospital, approximately 75% are associated with a urinary catheter. Methods. Our hospital, a large tertiary-care facility with a substantial spinal cord injury population and on-site nursing care center, were experiencing significant symptomatic CAUTI rates...

OBJECTIVE To determine the potential value of measuring umbilical cord diameter (UCD) at 11-14 weeks of gestation in screening for chromosomal defects. METHODS The UCD was measured in 1323 fetuses immediately before chorionic villus sampling for karyotyping at 11-14 weeks of gestation. In the group of chromosomally normal fetuses, regression analysis was used to determine the association betw...

This paper presents the development and evaluation for a graphical user interface (GUI) of a simulation tool in crisis management, which follows a User-Centered Design (UCD) approach. UCD places the focus of the development on the needs, abilities and the background of end users, by passing iteratively through four development phases: (1) the analysis of the end users’ personal background and w...

BACKGROUND Castleman disease is an uncommon lymphoproliferative disorder characterized as either unicentric or multicentric. Unicentric Castleman disease (UCD) is localized and carries an excellent prognosis, whereas multicentric Castleman disease (MCD) is a systemic disease occurring most commonly in the setting of HIV infection and is associated with human herpesvirus 8. MCD has been associat...

The controversy whether or not the Kardar-Parisi-Zhang (KPZ) equation has an upper critical dimension (UCD) is going on for quite a long time. Some approximate integral equations for the two-point function served as an indication for the existence of a UCD, by obtaining a dimension, above which the equation does not have a strong coupling solution. A surprising aspect of these studies, however,...
