The nature of the immune responses associated with COVID-19 pathogenesis and disease severity, as well breadth vaccine coverage duration immunity, is still unclear. Given unpredictability for developing a severe/complicated disease, there an urgent need in field predictive biomarkers COVID-19. We have analyzed IgG Fc N-glycan traits 82 SARS-CoV-2+ unvaccinated patients, at diagnosis, by nano-LC-ESI-MS. determined impact glyco-variations induction NK cells activation, further evaluating...

Pediatric appendicular bone sarcomas, including osteosarcoma and Ewing's sarcoma, are rare but aggressive malignancies that have a profound impact on survival, physical function, quality of life (QoL). Treatment options usually involve either limb-salvage surgery (LSS) or amputation (AMP), although evidence about outcomes among these approaches is still limited. A retrospective cohort study was conducted involving pediatric cases treated for sarcomas between 2000 2021 at the Instituto...

ABSTRACT A large variation in the severity of disease symptoms is one key open questions COVID-19 pandemics. The fact that only a small subset people infected with SARS-CoV-2 develop severe suggests there have to be some predisposing factors, but biomarkers reliably predict not been found so far. Since overactivation immune system implicated form and IgG glycosylation known involved regulation different processes, we evaluated association inter-individual N-glycome composition COVID-19....
