Organ Transplantation, Risks☆

, 2008
Viruses are among the most common causes of opportunistic infection after solid organ and hematopoietic stem cell transplantation (SOT and HSCT). Viral infection is associated with both direct (invasive disease) and indirect (immune modulation) effects affecting susceptibility to other infections and promoting allograft rejection.

Organizations, Risk Translation, and the Ecology of Risks: The Discursive Construction of a Novel Risk [PDF]

Academy of Management Journal, 2020
The contemporary ‘risk society’ is associated with the emergence of a wide range of risks characterised by uncertainty and unfamiliarity. These ‘novel’ risks pose a major challenge for organizations: their negative effects may be significant, but prevailing risk assessment techniques are limited in their ability to identify them.

Dose distribution in organs at risk.

, 2015
Doses [Gy] in organs at risk of all patients for 30 treatment fractions are demonstrated. Maximum shielding of the eyeballs resulted in mean doses in the optic nerves from 1.19 Gy to 46.18 Gy (max 63.44, min 0,88 Gy).
