Miriam Elfström,Jonas Blomqvist,Lars Engstrand,Lars Engstrand,Lars Engstrand,Mathias Uhlén,Carina Eklund,Fredrik Boulund,Camilla Lagheden,Marica Hamsten,Sara Nordqvist-Kleppe,Maike Seifert,Cecilia Hellström,Jennie Olofsson,Eni Andersson,August Jernbom Falk,Sofia Bergström,Emilie Hultin,Elisa Pin,Ville Pimenoff,Sadaf Sakina Hassan,Anna Månberg,Peter Nilsson,My Hedhammar,Sophia Hober,Johan Mattsson,Laila Sara Arroyo Mühr,Kalle Conneryd Lundgren +28 more
TL;DR: In this paper, the authors used multinomial logistic regression to determine associations with past or future sick leave using multivariate linear regression (MLR) regression and showed that high amounts of SARS-CoV-2 virus, as determined using PCR cycle threshold values, was associated with development of sickness in the next few weeks.

TL;DR: In this paper, the surface and core microbiota in the tonsils of CT and TH patients were compared using 16S rRNA gene sequencing of V3-V4 regions, and four representable tonsillar microbial types were identified, with one consisting of a higher abundance of Haemophilus and Neisseria, exclusively detected in the TH patients.
