    • Provider decision regret - a useful method for analysis of palliative thoracic re-irradiation for lung cancer? 

      Nieder, Carsten; Mannsåker, Bård; Yobuta, Rosalba; Haukland, Ellinor Christin (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-30)
      Background - The overall usefulness of palliative thoracic re-irradiation depends on the balance between efficacy, survival, and toxicity, and is difficult to judge from previous studies. In the absence of patient-reported data, we developed a method for provider decision regret that addresses the question “would we re-irradiate this patient again in light of the known outcome?” Furthermore, we ...

    • Symptom burden in patients with oligometastases at the start of palliative radiotherapy 

      Nieder, Carsten; Kämpe, Thomas A (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-04)
      Background/Aim: Recent studies suggested that patients with oligometastases have a better prognosis compared with those who have widespread dissemination. In both groups, radiotherapy is a commonly applied treatment. Patient-reported symptoms might depend on the burden of disease. Possibly, oligometastatic patients report lower scores for symptoms, such as fatigue or reduced appetite, which tend to ...

Additional precautions required in the management of children address their increased radiosensitivity, need for accompanying ...

    • BK polyomavirus evades innate immune sensing by disrupting the mitochondrial network and promotes mitophagy 

      Manzetti, Julia; Weissbach, Fabian H.; Graf, Fabrice E.; Unterstab, Gunhild; Wernli, Marion; Hopfer, Helmut; Drachenberg, Cinthia B.; Rinaldo, Christine Hanssen; Hirsch, Hans H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)
      Immune escape contributes to viral persistence, yet little is known about human polyomaviruses. BK-polyomavirus (BKPyV) asymptomatically infects 90% of humans but causes premature allograft failure in kidney transplant patients. Despite virus-specific T cells and neutralizing antibodies, BKPyV persists in kidneys and evades immune control as evidenced by urinary shedding in immunocompetent individuals. ...
