Residual blood loss in single use dialyzers: effect of different membranes and flux.

Aim/background: The aim of this study was to evaluate the residual blood loss in new type single use dialyzers under the usually prevailing conditions during hemodialysis and to investigate whether or not this loss is dependent on dialyzer membrane composition or flux characteristics.

Materials And Methods: In 158 hemodialysis (HD) patients, 158 single used dialyzers were studied in corresponding HD sessions. 52/158 dialyzers were made from modified cellulose (acetate, CA or triacetate, CTA) membrane and 106 from synthetic ones (58 with ethyl-vinyl-alcohol (EVAL), 48 with polyacrilonitrile (AN69)).

Myocardial infarction under the age of 36: prevalence of thrombophilic disorders.

It has been suggested that thrombotic tendency increases the risk of myocardial infarction (MI). To investigate the association between the risk of MI at a young age and genetic thrombogenic disorders (G20210A mutation in the prothrombin gene, G1691A mutation in the factor V gene and deficiencies of protein C, protein S and antithrombin III) we conducted a case-control study among 70 survivors of MI who had experienced the event before the age of 36 and 260 healthy subjects. The G20210A mutation in the prothrombin gene was found more often in young patients with MI than among controls (11.
