BACKGROUND We evaluated the predictive value of immature granulocyte (IG) percentage in comparison with white blood cell counts (WBC) and C-reactive protein (CRP), for infection, its invasiveness, and severity in critically ill patients. METHODS In 46 consecutive patients, blood samples were collected at the day (0) of a clinical suspicion of microbial(More)
The diagnostic use of procalcitonin for bacterial infections remains a matter of debate. Most studies have used ambiguous outcome measures such as sepsis instead of infection. We performed a systematic review and meta-analysis to investigate the diagnostic accuracy of procalcitonin for bacteraemia, a proven bloodstream infection. We searched all major(More)
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) have increased postoperative morbidity and mortality. Epidural analgesia (EDA) improves postoperative outcome but may worsen postoperative lung function. It is unknown whether patients with COPD benefit from EDA. The objective of this study was to determine whether patients with COPD(More)
Invasive Candida spp. infections are increasingly diagnosed in critically ill patients. For initial treatment, an echinocandin is recommended with a possible step-down to fluconazole when the patients' condition is improving and the isolate appears susceptible, but there are no data to support such policy. We studied the safety and efficacy of step-down(More)
The incidence of postoperative stroke ranges from 0.08% to 0.7% in noncardiac surgery. Recently, the PeriOperative ISchemic Evaluation (POISE) study reported an incidence of postoperative stroke of 1% in patients scheduled for noncardiac surgery when beta blockers were initiated immediately before surgery. To assess the association between chronic(More)
BACKGROUND In critically ill patients the incidence of invasive fungal infections caused by Candida spp. has increased remarkably. Echinocandins are recommended as initial treatment for invasive fungal infections. The safety and efficacy of micafungin compared to caspofungin is similar, but no comparison is made between anidulafungin and micafungin(More)
BACKGROUND The prediction of infection and its severity remains difficult in the critically ill. A novel, simple biomarker derived from five blood-cell derived parameters that characterize the innate immune response in routine blood samples, the intensive care infection score (ICIS), could be helpful in this respect. We therefore compared the predictive(More)
INTRODUCTION Risk factors for postoperative pulmonary embolism can often not be modified and are patient related. The purpose of this case control study was to identify possible modifiable risk factors for postoperative pulmonary embolism. MATERIALS AND METHODS We undertook a case control study among 210,269 patients who underwent noncardiac surgery from(More)
OBJECTIVES We aimed to study the safety and efficacy of procalcitonin in guiding blood cultures taking in critically ill patients with suspected infection. METHODS We performed a cluster-randomized, multi-centre, single-blinded, cross-over trial. Patients suspected of infection in whom taking blood for culture was indicated were included. The(More)
