Multivalvular endocarditis (MVE) is an uncommon presentation and mostly involves mitral and aortic valves. Here, we present a case of an MVE with an unusual and bizarre presentation on a Halloween night with a massive degree of valve destruction and right- and left-side involvement requiring emergent surgery. A 51-year-old male patient with intravenous drug usage presented with anorexia, fever, and dyspnea, rapidly progressing to septic shock with multiorgan dysfunction.

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.

Objective: Silicosis is a pneumoconiosis characterized by fibrosis of the lung parenchyma caused by the inhalation of silica particles. Silica dust inhalation is associated with inflammation and induction of oxidative stress in the lungs. This oxidative stress affects telomeres, which are short tandem DNA repeats that cap the end of linear chromosomes.

Despite the acknowledged role of genetic and certain lifestyle factors, comprehensive studies delineating the interactions between multiple risk factors and the mechanistic pathways involved are scarce. A greater understanding of both modifiable and non-modifiable risk factors for thyroid cancer is critical to prevent and manage the disease and could provide a scientific basis for future research into more appropriate lifestyles and living environments for people at high risk.
