A recently introduced blood gas/electrolyte analyzer (SenDx 100((R)), renamed ABL70) intended for point-of-care, near-patient, or stat laboratory use was evaluated simultaneously in four different institutions and compared with three different laboratory bench analyzers with respect to imprecision, inaccuracy (assessed by tonometry), and patient-sample(More)
PURPOSE To evaluate whether cystatin C in serum (sCyC) and urine (uCyC) can predict early acute kidney injury (AKI) in a mixed heterogeneous intensive care unit (ICU), and also whether these biomarkers can predict the need for renal replacement therapy (RRT). METHODS Multicenter prospective observational cohort study in patients ≥18 years old and with(More)
Critically ill patients are at high risk for developing acute renal failure (ARF). The prevention of ARF is of outmost importance in order to improve the increased morbidity and mortality associated with ARF. Unfortunately, there is lack of adequate endogenous markers that can identify renal dysfunction early - this hampers timely application of measures to(More)
The new selective access analysis system BM/Hitachi 917 was evaluated in an international multicentre study, mainly according to the ECCLS protocol for the evaluation of analysers in clinical chemistry. Forty-three different analytes, covering 56 different methods--enzymes, substrates, electrolytes, specific proteins, drugs and urine applications--were(More)
BACKGROUND The focus during the diagnostic process for patients with acute chest pain is to discriminate patients who can be safely discharged from those who are at risk for an acute coronary syndrome (ACS). In this study the diagnostic value of the clinical examination is compared with laboratory testing of troponin. METHODS This study included 710 chest(More)
The present study aims at the role of ferritin in the regulation of syncytiotrophoblast free iron levels. The differentiated cytotrophoblast cell in culture is used as a model for this maternal-fetal interface. Cytotrophoblast cells isolated from term placentae are cultured in iron-poor (Medium 199), iron-depleted [desferrioxamine(DFO)] and(More)
INTRODUCTION Preclinical and clinical studies suggest that mechanical ventilation contributes to the development of acute kidney injury (AKI), particularly in the setting of lung-injurious ventilator strategies. OBJECTIVE To determine whether ventilator settings in critically ill patients without acute lung injury (ALI) at onset of mechanical ventilation(More)
BACKGROUND Interpretation of serial high-sensitivity cardiac troponin (hs-cTn) measurements for the diagnosis of acute myocardial infarction (AMI) assumes random fluctuation of hs-cTn around an individual's homeostatic set point. The aim of this study was to challenge this diagnostic concept. METHODS Study 1 examined the presence of a diurnal hs-cTn(More)
BACKGROUND Chronic kidney disease (CKD) is associated with an increased cardiovascular disease mortality risk. It is, however, less clear at what point in the course from normal kidney function to CKD the association with cardiovascular disease appears. Studying the associations of estimated glomerular filtration rate (eGFR) and albuminuria with biomarkers(More)
