A special attention is paid to the possible biological effects of ionising radiations lately, an attitude which is justified by the continual increase of the exposed persons and the doses in-taken by these.

Cardiovascular events and intensity of treatment in polycythemia vera.
A b s t r ac t Background Current treatment recommendations for patients with polycythemia vera call for maintaining a hematocrit of less than 45%, but this therapeutic strategy has not been tested in a randomized clinical trial. Methods We randomly assigned 365 adults with JAK2-positive polycythemia vera who were being treated with phlebotomy, hydroxyurea, or both to receive either more intensive treatment (target hematocrit, <45%) (low-hematocrit group) or less intensive treatment (target hematocrit, 45 to 50%) (high-hematocrit group). The primary composite end point was the time until death from cardiovascular causes or major thrombotic events. The secondary end points were cardiovascula…
