      Siddiqui, Tahreem Ghazal; Cheng, Socheat; Gossop, Michael; Kristoffersen, Espen Saxhaug; Grambaite, Ramune; Lundqvist, Christofer (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-27)
      <i>Objectives</i> - Central nervous system depressants (CNSDs) such as opioids, benzodiazepine and Z-hypnotics are commonly used. However, CNSDs may influence cognitive function, especially in older hospitalised patients with comorbidities. The aim was to examine the association between CNSD use and cognitive function in older patients. We assessed global and domain specific cognitive function, among ...

    • Basilar Artery Occlusion Thrombectomy Technique: An International Survey of Practice Patterns 

      Klein, Piers; Herning, Ana; Drumm, Brian; Raymond, Jean; Abdalkader, Mohamad; Siegler, James E.; Kristoffersen, Espen Saxhaug (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-18)
      Background: Two recent trials demonstrated a benefit for endovascular therapy (EVT) in the treatment of basilar artery occlusion (BAO). In light of the expected increase in the use of EVT for BAO, we sought to understand the technique preferences of neurointerventionalists performing EVT for BAO.<p> <p>Methods: We conducted an international online survey of physician opinions on the use of EVT ...

      Objective: Developmental dysplasia of the hip (DDH) is a congenital condition affecting 2-3% of all infants. DDH increases the risk of osteoarthritis, is the cause of 30% of all total hip arthroplasties (THAs) in adults <40 years of age and can result in loss of life quality. Our aim was to explore the genetic background of DDH in order to improve diagnosis, management and longterm outcome.<p><p> ...

      Migraine is three times more prevalent in people with bipolar disorder or depression. The relationship between schizophrenia and migraine is less certain although glutamatergic and serotonergic neurotransmission are implicated in both. A shared genetic basis to migraine and mental disorders has been suggested but previous studies have reported weak or non-significant genetic correlations and five ...

    • Late Window Imaging Selection for Endovascular Therapy of Large Vessel Occlusion Stroke: An International Survey 

      Nguyen, Thanh; Klein, Piers; Berberich, Anne; Nagel, Simon; Abdalkader, Mohamad; Herning, Ana; Kristoffersen, Espen Saxhaug; Sandset, Else Charlotte (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-31)
      Background - Current stroke guidelines recommend advanced imaging (computed tomography [CT] perfusion or magnetic resonance imaging) prior to endovascular therapy (EVT) in patients with late presentation of large vessel occlusion. Adherence to guidelines may be constrained by resources or timely access to imaging. We sought to understand the factors which influence late window imaging selection for ...

    • The Norwegian PraksisNett: a nationwide practice-based research network with a novel IT infrastructure 

      Kristoffersen, Espen Saxhaug; Bjorvatn, Bjørn; Halvorsen, Peder Andreas; Nilsen, Stein; Fossum, Guro Haugen; Fors, Egil Andreas; Jørgensen, Pål; Øxnevad-Gundersen, Berit; Gjelstad, Svein; Bellika, Johan Gustav; Straand, Jørund; Rørtveit, Guri (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-13)
      Clinical research in primary care is relatively scarce. Practice-based research networks (PBRNs) are research infrastructures to overcome hurdles associated with conducting studies in primary care. In Norway, almost all 5.4 million inhabitants have access to a general practitioner (GP) through a patient-list system. This gives opportunity for a PBRN with reliable information about the general ...

    • Preventing and treating medication overuse headache 

      Alstadhaug, Karl Bjørnar; Ofte, Hilde Karen; Kristoffersen, Espen Saxhaug (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-01)
      The concept that headache treatment per se may be the cause of chronification of headache is not new,3 but our understanding of this concept, and the terminology defining it, have changed throughout the years. The criteria for MOH are based on expert consensus rather than formal evidence. According to the current definition in the latest (2013) International Classification of Headache Disorders–3 ...
