- BACKGROUND: A kidney with a single artery is preferred for donation. We wondered how often the donor is left with double or triple arteries, and whether this has any implications for long-term kidney function. METHODS: The consecutive living donors from 1984 to 1988 were reevaluated for kidney function and outcome. RESULTS: In total, 154 donor nephrectomies were performed with an open anterior technique. Ninety-eight patients were left with a single artery to the remnant kidney and 56 (36%) with more than one. Six individuals were left with 3 arteries. The mean age at donation was 48 +/- 12 years and mean age at reevaluation was 68 +/- SD 12 years. In the group with a remnant single artery, the mean preoperative serum creatinine level was 87 +/- 11 micromol/L, at 6 months it was 127 +/- 20 micromol/L, and in 2007 it was 90 +/- SD 23 micromol/L. The estimated glomerular filtration rate (GFR) was 67 +/- 18 mL/min. Thirty-three percent of donors (19/58) had developed hypertension. Among the group with multiple remnant arteries, the mean preoperative serum creatinine level was 87 +/- SD 11 micromol/L, at 6 months it was 131 +/- 21 micromol/L, and in 2007 it was 100 +/- 45 micromol/L. Estimated GFR was 64 +/- 16) mL/min. Twenty-eight percent of the donors (10/36) had developed hypertension. CONCLUSIONS: One third of kidney donors were left with double or triple arteries to the remnant kidney. The 20-year follow-up showed no significant difference in the renal function between the 2 groups.

- Scandiatransplant is the Nordic organ exchange organization having existed for almost 40 years. With close collaboration between transplant centers in the Nordic countries, it has been valuable to ensure the optimal usage of available organs. The heart is the most often exchanged organ within the collaboration. It has been decided to create a priority for hyperimmunized kidney patients for compulsory exchange of organs from deceased donors. The age of the deceased organ donors has changed from younger to older donors. The evaluation of deceased kidney transplantations and deceased liver transplantations from 1995 to 2007 is shown for 4 countries. Iceland by itself is performing living donor kidney transplantations with great intensity. Scandiatransplant will make efforts to present more data than just transplantation to yield a more complete picture of organ transplantation.

- Isoprene fluxes from a Salix viminalis (willow) plantation in western Sweden were measured using the relaxed eddy accumulation (REA) technique. Fluxes of up to 0.23 mu g m(-2) s(-1) could be observed. A standard emission factor at 303 K and a PAR flux of 1000 mu mol m(-2) s(-1) was estimated to 0.98 mu g m(-2) s(-1) by using the G93 algorithm. The chemistry of an air parcel passing over a willow coppice plantation was investigated utilising a Lagrangian box model in which the measured isoprene fluxes were used as input data. Dispersion after the field was accounted for by a procedure based on the Gaussian plume model. The calculations indicate that, in most cases, the isoprene emissions have a small effect on the local air quality.
