Cardiac function and volume status could play a critical role in the setting of weaning failure. B-type natriuretic peptide (BNP) is a powerful marker of cardiac dysfunction. We assessed the value of BNP during the weaning process. One hundred and two consecutive patients considered ready to undergo a 1-h weaning trial (T-piece or low-pressure support(More)
Isoelectric focusing on thin layer of acrylamide gel has been used for the characterization of 79 different variants of hemoglobin A. This method has replaced the cellulose acetate electrophoresis in clinical laboratories in Martinique, Guadeloupe and Creteil for the detection of abnormal hemoglobins in populations at risk. Up to now 15,000 samples from(More)
BACKGROUND Recent guidelines for use of cardiac troponin to detect cardiac damage and for cardiovascular risk stratification have made increasingly sensitive troponin assays important. Troponin assays continue to be plagued by interferences caused by heterophilic antibodies (HAs). We evaluated the performance of a revised cardiac troponin I (cTnI) assay(More)
This review primarily deals with methods for separations of hemoglobins. An introduction considers electrophoretic methods as well as those involving isoelectric focusing and chromatography. The main advantages or disadvantages of each procedure are discussed after each technical description. The chromatographic methods are mainly limited to those used in(More)
One hundred and fifty-one consecutive patients underwent allogeneic bone marrow transplantation (B.M.T.) following high-dose chemotherapy and single dose total body irradiation (T.B.I.) for hematologic malignancies between September 1980 and December 1985. All patients included in this study were treated using a 60 Co beam to deliver a prescribed dose of 10(More)
We describe how concentrations of chloride, urea, inorganic phosphate, and creatinine in urine can be measured directly, without manual sample dilution, in a discrete analyzer (the Technicon "RA-XT"). These methods were accurate for concentrations of chloride up to 280 mmol/L, urea up to 500 mmol/L, inorganic phosphate up to 50 mmol/L, and creatinine up to(More)
