      Background Self-rated health (SRH) is widely recognized as a clinically significant predictor of subsequent mortality risk. Although COVID-19 may impair SRH, this relationship has not been extensively examined. The ...
    • Novel oxygen desaturation parameters are associated with cardiac troponin I: Data from the Akershus Sleep Apnea Project 

      Sigurdardóttir, Fjóla Dögg; Øverby, Tonje Caroline; Nikkonen, Sami; Karhu, Tuomas; Dammen, Toril; Nordhus, Inger Hilde; Thorshov, Thea Christine; Einvik, Gunnar; Kainulainen, Samu; Leppänen, Timo; Arnardottir, Erna Sif; Töyräs, Juha; Omland, Torbjørn; Hrubos-Strøm, Harald (Journal article; Peer reviewed, 2022)
      Novel diagnostic markers for obstructive sleep apnea beyond the apnea–hypopnea index (AHI) have been introduced. There are no studies on their association with markers of subclinical myocardial injury. We assessed the ...

      Purpose: Cognitive functions in community-dwelling adults at high risk of obstructive sleep apnea have not been described and nor are associations between cognitive functions and obstructive sleep apnea severity fully ...
    • Persistent short nighttime sleep duration is associated with a greater post-COVID risk in fully mRNA-vaccinated individuals 

      Xue, Pei; Merikanto, Ilona; Chung, Frances; Morin, Charles M.; Espie, Colin; Bjorvatn, Bjørn; Cedernaes, Jonathan; Landtblom, Anne-Marie; Penzel, Thomas; De Gennaro, Luigi; Holzinger, Brigitte; Matsui, Kentaro; Hrubos-Strøm, Harald; Korman, Maria; Leger, Damien; Mota-Rolim, Sérgio; Bolstad, Courtney J.; Nadorff, Michael; Plazzi, Giuseppe; Reis, Catia; Chan, Rachel Ngan Yin; Wing, Yun Kwok; Yordanova, Juliana; Bjelajac, Adrijana Koscec; Inoue, Yuichi; Partinen, Markku; Dauvilliers, Yves; Benedict, Christian (Journal article; Peer reviewed, 2023)
      Short nighttime sleep duration impairs the immune response to virus vaccination, and long nighttime sleep duration is associated with poor health status. Thus, we hypothesized that short (<6 h) and long (>9 h) nighttime ...
    • Shift workers are at increased risk of severe COVID-19 compared with day workers: Results from the international COVID sleep study (ICOSS) of 7141 workers

      The present study had two main aims. First, to investigate whether shift/night workers had a higher prevalence and severity of COVID-19 compared with day workers. Second, to investigate whether people regularly working in ...
    • Sleep symptoms are essential features of long-COVID – Comparing healthy controls with COVID-19 cases of different severity in the international COVID sleep study (ICOSS-II)
