We investigate the influence of stochastic features (self-similarity, long range autocorrelation) of the input traffic on the performance of some QoS mechanisms. We model the impact of input traffic characteristics on queue distributions and packet loss probability observed at leaky bucket mechanism, at fixed priority scheduling of packets and on the RED(More)
AIM The objective of this study was to investigate the incidence, causes, the risk factors, etiologic agents and the outcomes of early-onset infections (EOIs) in very-low-birth-weight newborns in Polish neonatal intensive care units. METHODS Continuous prospective infection surveillance conducted during 2009 at 6 Polish neonatal intensive care units and(More)
BACKGROUND Late-Onset Bloodstream Infections (LO-BSI) continue to be one of the most important complications associated with hospitalization of infants born with very low birth weight (VLBW). The aims of this study were to assess the epidemiology of LO-BSI together with the risk factors and the distribution of causative pathogens at six Polish neonatal(More)
BACKGROUND The aims of our study were analysis of the occurrence of infections by members of the Enterobacteriaceae family in 6 Polish neonatal intensive care units in 2009, their drug resistance, the epidemiology of extended-spectrum β-lactamase (ESBL)-producing strains and the possibility of using modern tools of microbiology diagnosis in infection(More)
AIM OF STUDY 1. prospective record of infections; 2. prevention of nosocomial infections by providing current data about infections, which are significant for making therapeutic decisions. MATERIAL AND METHODS Recorded infections: early-onset sepsis (congenital), late-onset sepsis (acquired in hospital), necrotising enterocolitis (NEC), pneumonia.(More)
