BACKGROUND Obstructive sleep apnea (OSA) and obesity are often present concomitantly. Their potential contribution to inflammation remains an ongoing debate. The objectives of this study were to investigate whether variables of sleep-disordered breathing are associated with levels of myeloid-related protein-8/14 (MRP-8/14) or C-reactive protein (CRP), and(More)
Fibrinogen in plasma includes three main fractions; high-molecular-weight (HMW)-fibrinogen, low-molecular-weight (LMW)-fibrinogen, and very-low-molecular-weight (LMW')-fibrinogen. During acute-phase conditions, plasma fibrinogen levels and the HMW-/LMW-fibrinogen ratio increase rapidly due to increased synthesis of HMW-fibrinogen. The consequences of(More)
Freeze-dried plasma standards are often used to calibrate fibrinogen assays. Little is known, however, about the effect of freeze-drying on the clotting properties of fibrinogen. If these properties are altered, the use of freeze-dried calibration standards might influence the results obtained when applying clotting assays to determine fibrinogen(More)
BACKGROUND Cardiac troponins are the most sensitive and specific biochemical markers of myocardial injury and with the new high-sensitivity troponin methods very minor injuries of the heart muscle can be detected. The introduction of high-sensitivity assays has facilitated reference range adjustments and a revised cut-off point for myocardial infarction(More)
Moderate red wine consumption has been associated with decreased risk of coronary heart disease. Reduced plasma viscosity and fibrinogen levels have been launched as possible contributors to this risk reduction. The effect of moderate red wine consumption on plasma viscosity, however, has not been investigated in a prospective, randomized trial. We wanted(More)
BACKGROUND To determine whether the use of an electronic, sensor based stethoscope affects the cardiac auscultation skills of undergraduate medical students. METHODS Forty eight third year medical students were randomized to use either an electronic stethoscope, or a conventional acoustic stethoscope during clinical auscultation training. After a training(More)
INTRODUCTION Fibrinogen is a major determinant of plasma viscosity. The increased risk of atherothrombotic disease associated with a high fibrinogen concentration may partly be attributed to its effect on viscosity. Since the ratio between the three main fibrinogen subfractions high molecular weight (HMW)-, low molecular weight (LMW)-, and very low(More)
Assays based on clotting rate are commonly used as a routine method for determining the fibrinogen concentration in plasma. However, little is known about the influence of the acute-phase reaction on this assay. In order to disclose discrepancies between the fibrinogen concentrations obtained by a clotting rate assay (as described by Clauss) and a reference(More)
BACKGROUND The present study compares the value of additional use of computer simulated heart sounds, to conventional bedside auscultation training, on the cardiac auscultation skills of 3rd year medical students at Oslo University Medical School. METHODS In addition to their usual curriculum courses, groups of seven students each were randomized to(More)
