Association between high-dose steroid therapy, respiratory function, and time to discharge in patients with COVID-19: Cohort study.

Objective: To analyze whether there is an association between the use glucocorticoids at high doses, and the evolution of saturation/fraction of inspired oxygen (SAFI) or time to discharge, in patients hospitalized with COVID-19.

Methods: This was an observational study on a cohort of 418 patients admitted to three regional hospitals in Catalonia, Spain. As primary outcomes, we studied the evolution of SAFI in the first 48 h of treatment and the time to discharge.

Association between COVID-19 prognosis and disease presentation, comorbidities and chronic treatment of hospitalized patients.

Importance: The rapid pandemic expansion of the disease caused by the new SARS-CoV-2 virus has compromised health systems worldwide. Knowledge of prognostic factors in affected patients can help optimize care.

Objective: The objective of this study was to analyze the relationship between the prognosis of COVID-19 and the form of presentation of the disease, the previous pathologies of patients and their chronic treatments.

Influence of walls on the migration of non-Brownian spherical particles in creeping flow: a lattice Boltzmann study.

The influence of walls on binary encounters of spherical particles under creeping flow is studied by means of the lattice Boltzmann method. Depending on the initial particle displacement different behaviours can be observed, including the 'swapping' trajectories. The domain of the swapping trajectories is identified for interacting spheres with the same diameter; some preliminary results are given for the case of two spheres with different diameters.
