This study aimed to isolate phenolic compounds with antimicrobial action from the leaves of . The ethanolic extract (VmL-Et) was submitted to sephadex column separation, and some fractions were submitted to derivatization with BSTFA and analysed by GC-MS.

Relationship between clinical-epidemiological parameters and outcomes of patients with COVID-19 admitted to the intensive care unit: a report from a Brazilian hospital.

Background: People in low-income countries, especially those with low socio-economic conditions, are likelier to test positive for SARS-CoV-2. The unequal conditions of public health systems also increase the infection rate and make early identification and treatment of at-risk patients difficult. Here, we aimed to characterize the epidemiological profile of COVID-19 patients in intensive care and identify laboratory and clinical markers associated with death.
