      Nieder, Carsten; Stanisavljevic, Luka; Aanes, Siv Gyda; Mannsåker, Bård; Haukland, Ellinor Christin (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-12)
      Background: Established prognostic models, such as the diagnosis-specific graded prognostic assessment, were not designed to specifically address very short survival. Therefore, a brain metastases-specific 30-day mortality model may be relevant. We hypothesized that in-depth evaluation of a carefully defined cohort with short survival, arbitrarily defined as a maximum of 3 months, may provide ...
    • Adverse events as a measure of patient safety in cancer care 

      Haukland, Ellinor Christin (Doctoral thesis; Doktorgradsavhandling, 2020-09-11)
      “First, do no harm” is a fundamental element of health care and considered indistinguishable from the delivery of quality in health care. While cancer care has become more effective, it has also become more complex consequently increasing the risk for harm. We have assessed the extent and severity of treatment related adverse events in hospitalised cancer patients and elucidated how adverse events ...

    • Independent Validation of a Unifying Prognostic Model for Intracranial and Extracranial Metastasis-directed Radiotherapy 

      Nieder, Carsten; Stanisavljevic, Luka; Mannsåker, Bård; Haukland, Ellinor Christin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-06)
      We present the first calculations of the heavy flavor diffusion coefficient using lattice QCD with light dynamical quarks corresponding to a pion mass of around 320 MeV. For temperatures 195 MeV <T< 352 MeV, the heavy quark spatial diffusion coefficient is found to be significantly smaller than previous quenched lattice QCD and recent phenomenological estimates. The result implies very fast ...

      Nieder, Carsten; Haukland, Ellinor Christin; Mannsåker, Bård; Pawinski, Adam; Yobuta, Rosalba; Norum, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      <b>Background/Aim</b>: Compared to intravenous taxane chemotherapy, newer orally-available and/or less toxic agents for metastatic castration-resistant prostate cancer (MCRPC) may be associated with higher likelihood of starting treatment in patients with adverse prognostic features and limited life expectancy. To test this hypothesis, we analyzed the rates of treatment initiation during the last ...
    • Is there a seasonal variation of survival after systemic chemotherapy for metastatic castration-resistant prostate cancer in a rural part of North Norway? 

      Nieder, Carsten; Dalhaug, Astrid; Haukland, Ellinor Christin (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-19)
      The winter darkness or polar night induces endocrine and metabolic mechanisms, which might reduce the efficacy of cancer treatment and thus contribute to shorter survival. Moreover, season-and weather-related treatment delays and irregularities might also cause reduced efficacy of anti-cancer drugs. Therefore, this study evaluated the prognostic impact of timing of chemotherapy (start during winter ...
