Objectives: To compare the impact of COVID-19 on the clinical status and psychological distress of patients with immune-mediated rheumatic disease (IMRD) caused by SARS-CoV-2 infection with that of noninfected IMRD controls during a 6-month follow-up period.

Methods: The ReumaCoV Brazil is a longitudinal study designed to follow IMRD patients for 6 months after COVID-19 (patients) compared with IMRD patients without COVID-19 (controls). Clinical data, disease activity measurements and current treatments regarding IMRD and COVID-19 outcomes were evaluated in all patients.

FtsZ is a bacterial protein that plays a crucial role in cytokinesis by forming the Z-ring. This ring acts as a scaffold to recruit other division proteins and guide the synthesis of septal peptidoglycan, which leads to cell constriction. In its native state, the FtsZ protein from Escherichia coli (EcFtsZ) is a multi-oligomer comprising dimers, trimers, tetramers, and hexamers in a dynamic self-association equilibrium depending on its concentration.

Biofilms are complex microbial structures that have a significant impact on human health, industry and the environment. These complex structures represent one of the main mechanisms of microbial resistance, and their development constitutes a serious health problem. Therefore, the aim of this study was to verify the potential for inhibition and eradication of bacterial biofilm by salosodine, which is a steroidal alkaloid sapogenin found in plants of the Solanum genus.

Article Synopsis
  • The study focuses on a genus of plants known for their therapeutic properties, particularly for treating conditions like tuberculosis and urinary infections, with an emphasis on a species endemic to Brazil.
  • It identifies and analyzes the main compounds in its aqueous extract, finding Arbutin, Caffeic acid 4-O-glucoside, and Dihydroformononetin to be the most abundant; the gastrointestinal absorption and ability to cross the blood-brain barrier of these compounds were evaluated.
  • The research indicates that Arbutin and Dihydroformononetin may lead to drug synthesis and shows potential for phytotherapeutic use, although some mutagenicity predictions require cautious interpretation.
