In recent decades, waves of yellow fever virus (YFV) from the Amazon Rainforest have spread and caused outbreaks in other regions of Brazil, including the Cerrado, a savannah-like biome through which YFV usually moves before arriving at the Atlantic Forest. To identify the vectors involved in the maintenance of the virus in semiarid environments, an entomological survey was conducted after confirmation of yellow fever (YF) epizootics at the peak of the dry season in the Cerrado areas of the state of Minas Gerais. In total, 917 mosquitoes from 13 taxa were collected and tested for the presence of YFV.

Article Synopsis
- In Brazil, yellow fever virus (YFV) is primarily transmitted through wild mosquitoes and affects non-human primates, with its presence mainly in the Amazon but occasionally spreading to other regions, prompting human cases.* -
- A surveillance network was established in Minas Gerais in 2021, utilizing smartphone technology and collaboration between research and health institutions to monitor YFV in non-human primates, leading to rapid confirmation of the virus through advanced genetic sequencing.* -
- The detection of a new YFV strain in Minas Gerais reinforces the need for ongoing surveillance and quick response strategies to prevent future spillovers to humans, especially since no human cases have been reported in this instance.*
[American tegumentary leishmaniasis: a multivariate analysis of the spatial circuits for production of cases in Minas Gerais State, Brazil, 2007 to 2011].

The aim of this study was to explain the association between social-environmental factors and major land uses and the occurrence of cases of American tegumentary leishmaniasis (ATL) in the spatial circuits of production in Minas Gerais State, Brazil. This was an analytical-type ecological study based on secondary data on ATL divided by three-year period from 2007 to 2011, in which the analytical units were municipalities belonging to the spatial circuits. Two distinct stages were performed.

Research Design And Methods: This randomized multicenter trial compared the safety and efficacy of a basal-bolus insulin regimen with glargine once daily and glulisine before meals (n = 104) to sliding scale regular insulin (SSI) four times daily (n = 107) in patients with type 2 diabetes mellitus undergoing general surgery. Outcomes included differences in daily blood glucose (BG) and a composite of postoperative complications including wound infection, pneumonia, bacteremia, and respiratory and acute renal failure.
Purpose: To compare the safety and efficacy of continuous insulin infusion (CII) via a computer-guided and a standard paper form protocol in a medical intensive care unit (ICU).
Methods: Multicenter randomized trial of 153 ICU patients randomized to CII using the Glucommander (n = 77) or a standard paper protocol (n = 76). Both protocols used glulisine insulin and targeted blood glucose (BG) between 80 mg/dL and 120 mg/dL.
