Gut microbiota profile of COVID-19 patients: Prognosis and risk stratification (MicroCOVID-19 study).

Background: Gut microbiota is intrinsically associated with the immune system and can promote or suppress infectious diseases, especially viral infections. This study aims to characterize and compare the microbiota profile of infected patients with SARS-CoV-2 (milder or severe symptoms), non-infected people, and recovered patients. This is a national, transversal, observational, multicenter, and case-control study that analyzed the microbiota of COVID-19 patients with mild or severe symptoms at home, at the hospital, or in the intensive care unit, patients already recovered, and healthy volunteers cohabiting with COVID-19 patients.

Neuro-Behçet, pseudotumor cerebri and ocular signs: a rare association.

Introduction: The central nervous system involvement in Behçet's disease occurs in 5-30% of cases. The diagnosis of pseudotumor cerebri is even rarer (only 22 cases reported worldwide).

Purpose: To emphasize the importance of differential diagnosis in a case of pseudotumor cerebri in the context of ocular inflammation.
