    Breytingar í lungnavef á tölvusneiðmyndum sjúklinga með kórónuveirusjúkdóm 2019 (COVID-19) 
    Halldórsson, Arnljótur Björn; Axelsson, Gísli Þór; Jónsson, Helgi; Ísaksson, Jóhann Davíð; Harðardóttir, Hrönn; Guðmundsson, Gunnar; Hansdóttir, Sif (2021-10)
    Introduction Infections due to COVID-19 can lead to life threatening pneumonia. Accompanying severe disease are more prominent pulmonary changes on Computed Tomography (CT) scan of the chest. The goal of this study was to describe pulmonary CT changes ...

    Development of radiographic classification criteria for hand osteoarthritis : a methodological report (Phase 2) 
    Haugen, Ida K.; Felson, David; Abhishek, Abhishek; Berenbaum, Francis; Edwards, John James; Herrero Beaumont, Gabriel; Hermann-Eriksen, Merete; Hill, Catherine L.; Ishimori, Mariko; Jónsson, Helgi; Karjalainen, Teemu; Leung, Ying Ying; Maheu, Emmanuel; Mallen, Christian D.; Moe, Rikke Helene; Ramonda, Roberta; Ritschl, Valentin; Stamm, Tanja A.; Szekanecz, Zoltan; van der Giesen, Florus J.; Ritt, Marco J.P.F.; Wittoek, Ruth; Kjeken, Ingvild; Osteras, Nina; van de Stadt, Lotte A.; Englund, Martin; Dziedzic, Krysia S.; Marshall, M.; Bierma-Zeinstra, Sita; Hansen, Paul; Greibrokk, Elsie; Smeets, Wilma; Kloppenburg, Margreet (2022-02-04)
    ObjectivesIn Phase 1 of developing new hand osteoarthritis (OA) classification criteria, features associated with hand OA were identified in a population with hand complaints. Radiographic findings could better discriminate patients with hand OA and ...

    Do associations with hand OA vary by knee osteoarthritis phenotype? : Cross-sectional data from the Multicenter Osteoarthritis Study 
    Yau, Michelle S; Jónsson, Helgi; Lynch, John A; Lewis, Cora E.; Torner, James Corydon; Nevitt, Michael C.; Felson, David T. (2023-03)
    OBJECTIVE: Osteoarthritis (OA) is highly heterogeneous and has both biomechanical and systemic components that may not have the same etiology. We therefore aimed to identify specific knee OA phenotypes that may be more strongly associated with hand OA ...

    Meta-analysis of erosive hand osteoarthritis identifies four common variants that associate with relatively large effect 
    Styrkársdóttir, Unnur; Stefánsdóttir, Lilja; Thorleifsson, Gudmar; Andri Stefánsson, Ólafur; Sævarsdóttir, Sædís; Lund, Sigrún Helga; Rafnar, Thorunn; Hoshijima, Kazuyuki; Novak, Kendra; Oreiro, Natividad; Rego-Perez, Ignacio; Hansen, Channing; Kazmers, Nikolas; Kiemeney, Lambertus A; Blanco, Francisco J; Barker, Tyler; Kloppenburg, Margreet; Jurynec, Michael J; Gudbjartsson, Daniel F; Jónsson, Helgi; Þorsteinsdóttir, Unnur; Stefánsson, Kári (2023-06)
    OBJECTIVES: Erosive hand osteoarthritis (EHOA) is a severe subset of hand osteoarthritis (OA). It is unclear if EHOA is genetically different from other forms of OA. Sequence variants at ten loci have been associated with hand OA but none with EHOA. ...

    Respiratory function and CT abnormalities among survivors of COVID-19 pneumonia : a nationwide follow-up study 
    Axelsson, Gísli Þór; Halldorsson, Arnljotur Bjorn; Jónsson, Helgi; Eyþórsson, Elías Sæbjörn; Sigurðardóttir, Erla Sigríður; Harðardóttir, Hrönn; Guðmundsson, Gunnar; Hansdóttir, Sif (2022-10-01)
    INTRODUCTION: Considering the pulmonary burden caused by acute COVID-19, questions remain of respiratory consequences after recovery. The aim of the study was to describe respiratory function of COVID-19 pneumonia survivors at mid-term follow-up (median ...

    Using multivariable Mendelian randomization to estimate the causal effect of bone mineral density on osteoarthritis risk, independently of body mass index 
    Hartley, April; Sanderson, Eleanor; Granell, Raquel; Paternoster, Lavinia; Zheng, Jie; Smith, George Davey; Southam, Lorraine; Hatzikotoulas, Konstantinos; Boer, Cindy G.; Van Meurs, Joyce; Zeggini, Eleftheria; Gregson, Celia L.; Tobias, Jon H.; Stefánsdóttir, Lilja; Zhang, Yanfei; De Almeida, Rodrigo Coutinho; Wu, Tian T.; Teder-Laving, Maris; Skogholt, Anne Heidi; Terao, Chikashi; Zengini, Eleni; Alexiadis, George; Barysenka, Andrei; Bjornsdottir, Gyda; Gabrielsen, Maiken E.; Gilly, Arthur; Ingvarsson, Þorvaldur; Johnsen, Marianne B.; Jónsson, Helgi; Kloppenburg, Margreet G.; Luetge, Almut; Mägi, Reedik; Mangino, Massimo; Nelissen, Rob R.G.H.H.; Shivakumar, Manu; Steinberg, Julia; Takuwa, Hiroshi; Thomas, Laurent; Tuerlings, Margo; Babis, George; Cheung, Jason Pui Yin; Samartzis, Dino; Lietman, Steve A.; Slagboom, P.

Mark; Meulenbelt, Ingrid; Michael Lee, Ming Ta; Styrkársdóttir, Unnur (2022-08-01)
    Objectives: Observational analyses suggest that high bone mineral density (BMD) is a risk factor for osteoarthritis (OA); it is unclear whether this represents a causal effect or shared aetiology and whether these relationships are body mass index ...
