The aim of this study was to perform a systematic review of scientific papers that used spatial analysis tools in cases of leishmaniasis, in Brazil. The search for articles was carried out in PubMed, SciELO, Scopus and Web of Science databases. The keywords used in the identification of the articles were Thematic map AND Leishmaniasis, Spatial analysis AND Leishmaniasis, and Geoprocessing AND Leishmaniasis, in English language. A total of 360 articles were found, and 11 of them were analyzed after screening by title and abstract as well as reading of the full articles. The States studied were Sao Paulo, Acre, Maranhao, Piaui, Minas Gerais, Parana and Tocantins. Cutaneous leishmaniasis occurred predominantly in rural areas, with clusters in forest reserve regions or modified forest areas. Conversely, visceral leishmaniasis mainly occurred in peripheral and central urban areas associated with poorer environments and urban infrastructure, including worse sanitation. We conclude that the spatial distribution of leishmaniasis is closely related to the living environment of the risk population. The analyzed articles associated geospatial data with some risk factors for the disease, pointing out the locations where most cases occur, creating a relevant source to define control strategies.

The objective of this study was to evaluate and compare the bactericidal efficacy of2% chlorhexidine surfactant solution + 70% alcohol and 2% chlorhexidine surfactant solution + 0.5% chlorhexidine-alcohol, and standardize skin antisepsis for blood collection from donor dogs. One hundred and twenty skin swabsof the jugular regions of 20 dogs were evaluated. Swabs were distributed into six treatment(T) groups according to the disinfectant used and removal or retention of local hair: T1involved neither antisepsisnorhair removal; T2comprised 2% chlorhexidine + 0.5% chlorhexidine-alcoholwithout hair removal;T3 comprised 2% chlorhexidine + 70% alcohol without hair removal; T4comprised hair removal but no antisepsis;T5comprised 2% chlorhexidine + 0.5% chlorhexidine-alcohol withhair removal; and T6comprised 2% chlorhexidine + 70% alcohol with hair removal. Antiseptic agents were continuously applied in a single direction for a total of 3 min. Use of antiseptics was effective with or without hair removal, resulting in the absence of bacterial growth. Complete efficacy of the technique used in this study may have been due to the increased antiseptic application time. In conclusion,the antisepsis protocols tested in this study can be safely used for the collection of blood from dogs; although,removal of hair prior to antisepsis is still recommended.

O objetivo deste estudo foi demonstrar a importância de um programa de controle de qualidade em bancos de sangue veterinários. Durante todo o ciclo do sangue existem pontos críticos que podem causar a diminuição ou até a perda da qualidade dos componentes sanguíneos, levando à falta de segurança na utilização desses componentes, acarretando ineficiência da terapia ou ainda na piora do quadro do paciente receptor do sangue. O controle de qualidade é feito através de análises laboratoriais que indicam se os hemocomponentes estão dentro dos parâmetros de conformidade, verificando a qualidade dos mesmos. Na medicina, o controle de qualidade é feito de forma rigorosa, respeitando os parâmetros exigidos pela lei existente. Já na medicina veterinária, esses parâmetros não estão bem estabelecidos precisando de mais estudos nessa área.

The objective of this study was to perform a quality control assessment of red blood cells after standardization of the blood production stages. For this purpose, separation of the blood components to obtain red blood cells, the storage of the blood packets and an evaluation of blood quality were performed. The mean (± SD) volume, globular volume, hemoglobin and hemolysis percentage of the red blood cell concentrate were 299.77±30.08mL, 60.87±2.60%, 20.57±0.93g/DL and 0.09±0.07%, respectively. The means (± SD) of the volume, globular volume, total hemoglobin percentage of hemolysis and hemoglobin per unit of packed red blood cells after the storage period (8.83±6.73 days) were 57.55±3.01%, 20.30±0.89 0, 20±0.12%, and 60.90±7.65. The red blood cell packets were within the parameters of quality control established by Health Ministry legislation in humans and allow us to conclude that the standardization of blood production stages involves the selection of donors until the end of storage and is necessary to produce quality red blood cells. Quality control aims to find possible flaws in the procedures to be repaired, increasing transfusion safety.
