BACKGROUND Adults with cyanotic congenital heart disease and elevated hematocrit levels are often phlebotomized because of an assumed risk of cerebral arterial thrombotic stroke. Whether a relation exists between hematocrit level, symptomatic erythrocytosis (hyperviscosity), and stroke remains to be established in this patient population. METHODS AND RESULTS Accordingly, 112 cyanotic patients...

BACKGROUND In recent years, the continuous noninvasive hemoglobin measurement has been offered by devices using advanced pulse oximetry technology. Accuracy has been established in healthy adults as well as in surgical and intensive care unit patients but not in the setting of acute hemorrhage. In this study, we evaluated the accuracy of such a device in the clinical setting of preoperative phl...

Abstract Aim The aim of this quality improvement project was to provide a solution improve the confidence and skill Oral Maxillofacial Dental Core Trainees (DCTs) in venepuncture by attending phlebotomy training sessions. DCTs within hospital where undertaken are dentally qualified often not taught principles during their undergraduate degree. Furthermore, they rarely gain hands-on experience c...

With this study we tested the hypothesis that 6 wk of endurance training increases maximal cardiac output (Qmax) relatively more by elevating blood volume (BV) than by inducing structural and functional changes within the heart. Nine healthy but untrained volunteers (Vo2max 47 ± 5 ml·min(-1)·kg(-1)) underwent supervised training (60 min; 4 times weekly at 65% Vo2max for 6 wk), and Qmax was dete...

Staphylococcus aureus and coagulase-negative staphylococci are the main cause of sepsis in Neonatal Intensive Care Unit (NICU). Central venous catheters (CVCs) are an important part of critical neonates' treatment and are associated with sepsis. The aim of this study was to investigate two outbreaks caused by Staphylococcus aureus and Staphylococcus epidermidis associated with CVC inserted by p...

The pharmacodynamics (PD) of the reticulocyte response resulting from phlebotomy-induced erythropoietin (EPO) was investigated in adult sheep. The anemia caused by the controlled phlebotomy (Hb < 4 g/dl, t = 0) resulted in a rapid increase in EPO with peak concentrations from 200 to 1400 mU/ml at 0.5 to 3 days generating a delayed reticulocyte response with peak levels from 9.3 to 14.1% at 2.5 ...

Thirty-five year-old Amadeus Mozart died in Vienna after an acute illness that lasted only 15 days but no consensus has been reached on the cause of his death. From many letters written by his farther it is almost certain that he experienced at least three episodes of acute rheumatic fever attack in his childhood, and a relapse of rheumatic fever was suggested to have killed Mozart, although de...

Aim. Chronic hepatitis C (CHepC) is frequently associated with hepatic iron overload, yet mechanisms underlying iron-induced liver injury have not been elucidated. We examined the significance of iron deposition in hepatocytes (HC) and reticuloendothelial cells (REC) in CHepC. Methods. Stainable hepatic iron was scored according to the iron deposition pattern in 373 patients. The levels of seru...
