      Background: Results showing that sera from double vaccinated individuals have minimal neutralizing activity against Omicron have been interpreted as indicating the need for a third vaccine dose for protection. However, there is little information about early immune responses to Omicron infection in double vaccinated individuals.<p> <p>Methods: We measured inflammatory mediators, antibodies to the ...
    • Cognitive rehabilitation in post-COVID-19 condition: A study protocol for a randomized controlled trial

      Background: Post-COVID-19 condition is frequently comprised of persistent cognitive sequela, including deficits in attention and executive functions (EFs), which can act as a barrier for regaining pre-illness functional levels. Goal Management Training (GMT) is a cognitive rehabilitation (CR) intervention for improving attention and EFs that has received empirical support in studies of other ...
    • A comparison of extended spectrum β-lactamase producing Escherichia coli from clinical, recreational water and wastewater samples associated in time and location 

      Jørgensen, Silje; Søraas, Arne Vasli; Arnesen, Lotte S; Arnesen, Lotte Pia Stenfors; Leegaard, Truls Michael; Sundsfjord, Arnfinn; Jenum, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-17)
      Extended spectrum β-lactamase producing Escherichia coli (ESBL-EC) are excreted via effluents and sewage into the environment where they can re-contaminate humans and animals. The aim of this observational study was to detect and quantify ESBL-EC in recreational water and wastewater, and perform a genetic and phenotypic comparative analysis of the environmental strains with geographically associated ...
    • Fecal carriage of extended spectrum β-lactamase producing Escherichia coli and Klebsiella pneumoniae after urinary tract infection - A three year prospective cohort study 

      Jørgensen, Silje; Søraas, Arne Vasli; Sundsfjord, Arnfinn; Liestøl, Knut; Leegaard, Truls Michael; Jenum, Pål (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-07)
      We have performed a prospective cohort study to investigate the duration of and risk factors for prolonged fecal carriage of ESBL-producing Escherichia coli or Klebsiella pneumoniae in patients with community acquired urinary tract infection caused by these bacteria. From 2009 to 2011, 101 Norwegian patients were recruited. Stool swabs and questionnaires were collected every three months for one ...
    • Omicron Variant Generates a Higher and More Sustained Viral Load in Nasopharynx and Saliva Than the Delta Variant of SARS-CoV-2 

      Granerud, Beathe Kiland; Ueland, Thor; Lind, Andreas; Søraas, Arne Vasli; Fevang, Børre; Steffensen, Anne Katrine; Al-Baldawi, Huda; Lund-Johansen, Fridtjof; Aukrust, Pål; Halvorsen, Bente Evy; Dahl, Tuva Børresdatter; Dudman, Susanne; Müller, Fredrik; Holter, Jan Cato (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-31)
      The Omicron variant of SARS-CoV-2 spreads more easily than earlier variants, possibly as a result of a higher viral load in the upper respiratory tract and oral cavity. Hence, we investigated whether the Omicron variant generates a higher viral load than that of the Delta variant in saliva and nasopharynx. Both specimens were collected from 52 Omicron and 17 Delta cases at two time points one week ...
    • Vaccine associated benign headache and cutaneous hemorrhage after ChAdOx1 nCoV-19 vaccine: A cohort study 

      Schultz, Nina Haagenrud; Søraas, Arne Vasli; Sørvoll, Ingvild Hausberg; Akkøk, Cigdem Ahaein; Vetlesen, Annette; Bhamra, Jagjit Singh; Ahlen, Maria Therese; Holme, Pål Andre; Aamodt, Anne Hege; Skagen, Karolina Ryeng; Skattør, Thor Håkon; Skjelland, Mona; Wiedmann, Markus (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-17)
      Objectives Fatal complications have occurred after vaccination with ChAdOx1 nCoV-19, a vaccine against Covid-19. Vaccine-induced immune thrombotic thrombocytopenia (VITT) with severe outcome is characterized by venous thrombosis, predominantly in cerebral veins, thrombocytopenia and anti-PF4/polyanion antibodies. Prolonged headaches and cutaneous hemorrhages, frequently observed after the ChAdOx1 ...
