Hospital mortality due to infective endocarditis: Analysis of risk factors in a developing country.

Introduction: Infective endocarditis (IE) is a disease with high mortality that, in recent decades, has experienced changes in its epidemiology, pathogenesis, and microbiology. Therefore, understanding its landscape and risk factors for mortality is essential.

Objective: To identify the epidemiological, clinical, laboratory, etiological, and echocardiographic profile of patients hospitalized with IE and to determine predictors for in-hospital mortality.

Schistosomiasis: A neglected cause of pulmonary arterial hypertension in Brazil.

Schistosomiasis is a prevalent disease in Brazil whose etiological agent is Schistosoma mansoni, the main species associated with pulmonary arterial hypertension (PAH), a serious complication. It is estimated that this complication affects up to 15% of patients with the hepatosplenic form of the disease. Despite being an endemic country, Brazil does not have a screening scheme for cases of PAH associated with schistosomiasis (PAH-Sch), nor protocols for notification and treatment of this vascular complication.
