OPEN NOW – Science Challenge 2023

What is the ORCHESTRA Science Challenge?

Do you want to work with pan-european data regarding COVID-19 infection including Follow-up? Then consider applying for our Science Challenge. Work Package 2 (COVID-19 cohorts and long-term sequelae) data from 4 participating cohorts will be provided. The analysation is going to be be performed with the Federated Learning program DataSHIELD (please also see Release Notes for current version). Within the next months we will select the best applications and accompany these winners during the process of data preparation, analysis and publication.

Who won the ORCHESTRA Science Challenge?

Two winners have been selected among all applicants. We look forward to collaborate with both winners and are happy to support their research into COVID-19. Martin Brizuela (Hospital Vélez Sarsfield, Buenos Aires, Argentina) will examine the data of patients under 18 years with and without risk factors such as HIV. In this group he will analyse predictors of Long COVID/multisystemic inflammatory disease, predictors of severity and mortality of SARS-COV-2 infections, and lower respiratory infections during and after acute COVID-19 infections. The EuCARE-POSTCOVID Project (Milan, Italy) will assess persisting COVID-19 symptoms within 1 year after acute infection in outpatients/patients with mild/moderate disease treated with a 3-day course of Remdesivir or Ritonavir compared to patients with other or no drugs administered.
