- The introduction of treatment with recombinant human erythropoietin (rhEPO) has raised the possibility of deleterious effects on early kidney graft function. Due to renal anemia, the great majority of patients waiting for kidney transplantation until now have had a low hematocrit. It has been suggested that a low hematocrit is beneficial for early kidney graft function by protecting the transplanted kidney from so-called reperfusion damage, which results in delayed onset of renal function. We have retrospectively examined the early function of 26 kidney grafts transplanted to uremic patients with rhEPO corrected anemia. Compared with a randomized control group no significant differences were seen in the rate of immediate onset of graft function, graft survival or serum levels of creatinine one year after transplantation. We conclude that the reversing of anemia by rhEPO in recipients of cadaver kidneys does not impair early graft function.

Parametric Signal Modelling using Laguerre Filters
- 1990
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Autoregressive (AR) modelling is generalized by replacing the delay operator by discrete Laguerre filters. The motivation is to reduce the number of parameters needed to obtain useful approximate models of stochastic processes, without increasing the computational complexity. Asymptotic statistical properties are investigated. Several AR model estimation results are extended to Laguerre models. In particular, it is shown how the choice of Laguerre time constant affects the resulting estimates. A Levinson-type algorithm for computing the Laguerre model estimates in an efficient way is also given. The Laguerre technique is illustrated by two simple examples.
