      Jøraholmen, May Wenche (Doctoral thesis; Doktorgradsavhandling, 2016-02-19)
      <p>The vaginal inflammation and infection are one of the major female health issues, and unfortunately rather neglected. The anatomical structure and physiological conditions make vagina vulnerable to inflammation and infection, which if not successfully treated, can lead to deteriorating female health conditions. In pregnant patients, the pregnancy outcome can be severely affected. Although a ...
    • Modulation of Cardiometabolic Health by Dietary Supplementation with Calanus oil 

      Jansen, Kirsten Maria (Doctoral thesis; Doktorgradsavhandling, 2021-09-17)
      Obesity leads to alterations in myocardial metabolism, expressed as an increased utilization of fat for energy purposes at the expense of carbohydrate. This shift in energy metabolism is associated with impairment of ventricular function which can lead to heart failure. This thesis raises the question of whether dietary supplementation with Calanus oil, a novel marine oil derived from the marine ...

    • Hippocampal plasticity: Development of connectivity and growth hormone modulation of place cells and behavior 

      Haugland, Kamilla Gjerland (Doctoral thesis; Doktorgradsavhandling, 2021-06-17)
      The hippocampus is remarkably plastic and has the ability to modify its processes throughput the lifetime. During development, the hippocampus is exceedingly plastic as new neurons and connections are taking form. Nevertheless, the neural circuits of the hippocampus keep modifying in the adult. The factors contributing to hippocampal plasticity are still elusive. In this thesis, I present three ...
    • Combined effects of cancer and prothrombotic genotypes on the risk of venous thromboembolism 

      Skille, Hanne (Doctoral thesis; Doktorgradsavhandling, 2021-06-18)
      Venous thromboembolism (VTE), a collective term for deep vein thrombosis and pulmonary embolism, is a severe and multifactorial disease. Heritability has been found to explain up to 60% of VTE events, however, the role of genetics on VTE in cancer is scarcely studied. VTE occurs frequently in cancer patients and is a common cause of morbidity and mortality in this patient group. The aim of the present ...
    • Immunological biomarkers in prostate cancer - A retrospective cohort study utilizing immunohistochemistry on tissue microarrays for evaluation of immune biomarker expression and experimental in vitro assays 

      Ness, Nora (Doctoral thesis; Doktorgradsavhandling, 2021-06-11)
      <p><i>Background:</i> Prostate cancer is a very common, but particularly heterogenic cancer form. Whilst some patients have a very aggressive course with a fatal outcome, the majority of patients have slow-growing disease with low risk of death or significant symptoms. Unfortunately, doctors do not possess sufficient prognostic tools, and there is a high risk of overtreatment with unnecessary ...

      <p>Background: Osteoporotic fractures constitute a major health- and economic burden worldwide and because of an aging population the burden is estimated to rise. The individual consequences of fractures are severe. Norway has one of the highest fracture incidences in the world. The etiology of fracture risk at old age is less optimal bone mass accumulation in childhood and adolescence, rapid ...
    • Prediction of unfavorable outcome in Juvenile Idiopathic Arthritis (JIA) and assessment of the long-term outcomes in JIA-associated uveitis – A prospective Nordic multicenter study of JIA from childhood to adulthood 

      Rypdal, Veronika Gjertsen (Doctoral thesis; Doktorgradsavhandling, 2021-05-21)
      Juvenile idiopathic arthritis (JIA) is a chronic childhood disease with joint inflammation as the main feature. The course and outcomes are heterogeneous with a large span in disease severity. There is increasing evidence that early aggressive treatment may modify the disease course in JIA. Precise determination of disease prognosis is therefore sought to guide early decisions on which children need ...
    • Development of a prognostic model for unfavorable outcome after lumbar microdiscectomy 

      Werner, David Andreas Thomas (Doctoral thesis; Doktorgradsavhandling, 2021-05-11)
      The aim of this thesis was to develop a prognostic model for unfavorable outcome 12 months after surgical treatment of a lumbar disc herniation (lumbar microdiscectomy). While the surgical procedure is rather uniform, with little technical variation, the reported outcomes are quite heterogenous. This might be due to different expectations by patients, or due to suboptimal surgical indication as ...
    • Studies on the Chain of Survival in Out-of-Hospital Cardiac Arrest 

      Lund-Kordahl, Inger (Doctoral thesis; Doktorgradsavhandling, 2021-05-20)
      <p><i>Background:</i> Sudden death due to out-of-hospital cardiac arrest (OHCA) remains a major health issue with estimated 250-300.000 cases in Europe/year. Survival after OHCA depends on a well-functioning Chain of Survival. The Chain of Survival concept of early access, early cardiopulmonary resuscitation (CPR), early defibrillation and good post-resuscitation care is the documented and recommended ...
