Some epidemiological aspects of leishmaniasis in the municipality of Formiga, Brazil, an important touristic site, were evaluated. Those included phlebotomine sand fly vectors, canine infection, and geoprocessing analysis for determining critical transmission areas. Sand flies (224 insects) belonging to ten different species were captured. The most captured species included Lutzomyia longipalpis (35.3%), Lutzomyia cortelezzii (33.5%), and Lutzomyia whitmani (18.3%). A significant correlation between sand fly densities and climatic conditions was detected. Serological diagnosis (DPP and ELISA) was performed in 570 dogs indicating a prevalence of 5.8%. After sequencing the main species circulating in the area were Leishmania infantum and Leishmania braziliensis. Spatial analysis demonstrated that vegetation and hydrography may be related to sand fly distribution and infected dogs. The municipality of Formiga has proven leishmaniasis vectors and infected dogs indicating the circulation of the parasite in the city. Correlation of those data with environmental and human cases has identified the critical areas for control interventions (south, northeast, and northwest). In conclusion, there is current transmission of visceral and canine human cases and the city is on the risk for the appearance of cutaneous cases.

This work opens a new path to fight parasites by targeting host molecular functions by repurposing available and approved drugs. We created a novel approach to identify key proteins involved in any biological process by combining gene regulatory networks and expression profiles.

Despite the increasing number of manuscripts describing potential alternative antileishmanial compounds, little is advancing on translating these knowledges to new products to treat leishmaniasis. This is in part due to the lack of standardisations during pre-clinical drug discovery stage and also depends on the alignment of goals among universities/research centers, government and pharmaceutical industry. Inspired or not by drug repurposing, metal-based antileishmanial drugs represent a class that deserves more attention on its use for leishmaniasis chemotherapy. Together with new chemical entities, progresses have been made on the knowledge of parasite-specific drug targets specially after using CRISPR/Cas system for functional studies. In this regard, Leishmania parasites undergoe post-translational modification as key regulators in several cellular processes, which represents an entire new field for drug target elucidation, once this is poorly explored. This perspective review describes the advances on antileishmanial metallodrugs and the elucidation of drug targets based on post-translational modifications, highlighting the limitations on the drug discovery/development process and suggesting standardisations focused on products addressed to who need it most.

Objetivo: O objetivo principal deste trabalho é verificar como se dá a inclusão do aluno surdo nas instituições de ensino. Para os alcances dos objetivos propostos será realizada uma revisão narrativa da literatura. Revisão bibliográfica: A Constituição Federal de 1988 diz que todos são iguais perante a lei, não podendo haver distinção de qualquer natureza, sendo garantidos o direito à vida, à liberdade, à igualdade, à segurança e à propriedade, enfatizando também a proibição de qualquer tipo de discriminação. Dentre a legislação que permeia a comunidade surda, a Lei 10.436/2002 e o Decreto 5.626/2005, são considerados os principais marcos da luta pelos direitos desses indivíduos. A Lei 12.319/2010, que regulamenta a profissão de Tradutor e Intérprete da Língua Brasileira de Sinais (ILS), é de extrema relevância para que se promova uma inclusão efetiva do surdo nos âmbitos sociais. Considerações finais: Apesar de existirem diversas legislações que favorecem a inclusão da pessoa surda, ainda a muito que se conquistar para a efetivação dos direitos desses indivíduos, sendo o ILS um agente imprescindível no processo de inclusão e para um efetivo aprendizado.
