ABSTRACT The Brazilian Navy (BN) has its combatant force concentrated in an area with only one exit to the sea. Nevertheless, Brazil has an extensive coast that needs to be patrolled and, in case of any kind of conflict, the BN must be able to defend the sovereignty and interests of the country. For this purpose, a robust and decentralized naval force is necessary, which allows the fulfillment of its mission. This paper aims to classify the most suitable cities in Brazil to be established as naval bases by applying the ELECTRE-MOr hybrid method. Seventeen cities were analyzed, which have an opening to the sea and a pre-existing minimum port structure. The alternatives were evaluated by specialists from the BN, with more than twenty years of active service, in the light of operational, economic and strategic criteria. As a result, five alternatives were classified as the most indicated headquarters for the decentralization of the naval power: Belém/PA, São Luis/MA, Fortaleza/CE, Recife/PE and Aratu/BA. This article presents relevance to academia and society, as it represents the application of a method in the state of the art to support the decision-making process in a significant problem for the sovereignty of Brazil, presenting a methodology that can be applied in issues of tactical, operational, strategic and political levels.

ABSTRACT Military issues have great relevance worldwide since they affect the security and sovereignty of nations. In this context, the application of Multicriteria Decision Analysis (MCDA) methods is important because accurate decision-making is the deciding factor for success, which can reduce expenses and increase defense capacity. This paper aims to present a literature review on the main applications of MCDA in the military area, considering the tactical, operational and strategic spheres. The methodology includes a bibliometric study and literature review of documents from the Scopus and Web of Science databases. The bibliometric study identified the document type, language, year of publication, authors, author network, author’s publications, affiliation, keyword clusters, the field of knowledge, country and the main applied MCDA methods in military problems. The literature review allows us to verify that, as well as in other areas of knowledge, the Analytic Hierarchy Process (AHP) is the most applied MCDA method in the military area.

ABSTRACT Background: Inflammatory bowel disease (IBD) is an immune-mediated disorder that includes Crohn’s disease (CD) and ulcerative colitis. CD is characterized by a transmural intestinal involvement from the mouth to the anus with recurrent and remitting symptoms that can lead to progressive bowel damage and disability over time. Objective: To guide the safest and effective medical treatments of adults with CD. Methods: This consensus was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's disease and Colitis (GEDIIB)). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All included recommendations and statements were endorsed in a modified Delphi panel by the stakeholders and experts in IBD with an agreement of at least 80% or greater consensus rate. Results and conclusion: The medical recommendations (pharmacological and non-pharmacological interventions) were mapped according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus is targeted towards general practitioners, gastroenterologists, and surgeons interested in treating and managing adults with CD and supports the decision-making of health insurance companies, regulatory agencies, and health institutional leaders or administrators.

RESUMO Contexto: A doença inflamatória intestinal (DII) é uma doença imunomediada que inclui a doença de Crohn (DC) e a retocolite ulcerativa. A DC é caracterizada por um envolvimento intestinal transmural da boca ao ânus com sintomas recorrentes e remitentes que podem levar a danos intestinais progressivos e incapacidade ao longo do tempo. Objetivo: Orientar os tratamentos médicos mais seguros e eficazes de adultos com DC. Métodos: Este consenso foi desenvolvido por autores que representam gastroenterologistas e cirurgiões brasileiros especialistas em doenças colorretais (GEDIIB, Organização Brasileira de Doença de Crohn e Colite). Uma revisão sistemática das evidências mais recentes foi realizada para apoiar as recomendações/declarações. Todas as recomendações e declarações incluídas foram endossadas em um painel Delphi modificado pelas partes interessadas e especialistas em DII com uma concordância de pelo menos 80% ou mais. Resultados e conclusão: As recomendações médicas (intervenções farmacológicas e não farmacológicas) foram mapeadas de acordo com o estágio de tratamento e gravidade da doença em três domínios: manejo e tratamento (intervenções medicamentosas e cirúrgicas), critérios para avaliar a eficácia do tratamento médico, e acompanhamento/monitoramento do paciente após o tratamento inicial. O consenso é direcionado a clínicos gerais, gastroenterologistas e cirurgiões interessados em tratar e gerenciar adultos com DC e apoia a tomada de decisões de companhias de seguro de saúde, agências reguladoras e líderes ou administradores de instituições de saúde.

ABSTRACT Background: Inflammatory bowel diseases are immune-mediated disorders that include Crohn’s disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. Objective: This consensus aims to provide guidance on the most effective medical management of adult patients with UC. Methods: A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn’s Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. Results and conclusion: The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.

RESUMO Contexto: As doenças inflamatórias intestinais são doenças imunomediadas que incluem a doença de Crohn (DC) e a retocolite ulcerativa (RCU). A RCU é uma doença progressiva que acomete a mucosa colorretal causando sintomas debilitantes levando a alta morbidade e incapacidade laboral. Como consequência da inflamação crônica do cólon, a RCU também está associada a um risco aumentado de câncer colorretal. Objetivo: Este consenso visa fornecer orientações sobre o manejo médico mais eficaz de pacientes adultos com RCU. Métodos: As recomendações do consenso foram desenvolvidas por gastroenterologistas e cirurgiões colorretais referências no Brasil (membros da Organização Brasileira para Doença de Crohn e Colite [GEDIIB]). Uma revisão sistemática, incluindo as evidências mais recentes, foi conduzida para apoiar as recomendações. Todas as recomendações foram endossadas pelas partes interessadas/especialistas em doença inflamatória intestinal usando um Painel Delphi modificado. O nível de concordância para alcançar consenso foi de 80% ou mais. Resultados e conclus ão: As recomendações médicas (farmacológicas e não farmacológicas) foram mapeadas de acordo com o estágio de tratamento e gravidade da doença em três domínios: manejo e tratamento (intervenções medicamentosas e cirúrgicas), critérios para avaliar a eficácia do tratamento médico, e acompanhamento/monitoramento do paciente após o tratamento inicial. O consenso foi direcionado a clínicos gerais, gastroenterologistas e cirurgiões que tratam pacientes com RCU e apoia os processos de tomada de decisão por companhias de seguro de saúde, agências reguladoras, líderes institucionais de saúde e administradores.

Abstract Paper aims This paper aims to select the best helicopter to be acquired by the Brazilian Navy (BN), enabling greater logistical and combat capacity in marine operations. For this purpose, we applied the AHP-TOPSIS-2N, a hybrid multicriteria method composed by the Analytic Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and two normalization procedures (2N). Originality In this paper, a real military case study is conducted to support the decision-making process in BN, contributing to the better performance of the Brazilian Armed Forces. The application of the methodology resulted in two lists of ordering and prioritization of helicopters, providing transparency and simplicity to the decision-making process. Research method We analyzed six aircraft models, considering attack helicopters used by the Armed Forces of developed countries, in the light of their operational and tactical criteria. The selected helicopter would be employed in the fire support and reconnaissance, required by the Brazilian Marine Corps Amphibious Operations. Main findings After the application of the method, the AH-64E APACHE was chosen as the most suitable helicopter to be acquired by the Brazilian Navy. Implications for theory and practice This study brings valuable contribution to academia and society, since it represents the application of a Multi-criteria Decision Analysis (MCDA) method in the state of the art to contribute to the solution of a real problem of the BN. The methodology presented in this paper can notably be used to solve real problems of the most varied types – tactical, operational and strategic – thus being a very useful method for decision-making.

Este estudo teve como objetivo avaliar a atividade antifúngica de extratos de M. oleifera frente a fungos isolados de camarões, cultivados em água doce, e testar a toxicidade dos extratos em larvas de Macrobrachium amazonicum. Os extratos etanólicos de vagens, sementes, folhas, caules e flores e o extrato clorofórmico de flores de M. oleifera foram testados contra 14 cepas de Candida spp. e 10 cepas de Hortaea werneckii isolados da água de cultivo e do trato digestório de M. amazonicum. A atividade antifúngica foi determinada por microdiluição, com base nos documentos M27-A3 e M38-A2 do CLSI. A toxicidade foi avaliada por exposição das larvas de M. amazonicum a concentrações entre 10-1000 mg mL-1 dos extratos, realizando contagem de larvas mortas (CL50), após 24 horas. Os melhores resultados foram verificados com o extrato clorofórmico de flores, agindo frente a todas as cepas testadas, com concentrações inibitórias mínimas variando entre 0,019-2,5 mg mL-1. O extrato etanólico de folhas, flores e sementes agiu ante 22/24, 21/24 e 20/24 cepas, respectivamente. O extrato de vagens foi eficaz contra cepas de Candida spp. (14/24) e o extrato de caule apenas contra quatro cepas de H. werneckii (4/24). Os extratos de sementes, flores (fração clorofórmica), caules e folhas apresentaram baixa ou nenhuma toxicidade, enquanto que extratos de vagens e flores (fração etanólica) apresentaram toxicidade moderada. Assim, observou-se atividade antifúngica dos extratos em Candida spp . e H. werneckii com uma ampla margem de segurança para as larvas de M. amazonicum, demonstrando ser promissor para o manejo sustentável dos efluentes do cultivo de M. amazonicum

This study aimed to evaluate the antifungal activity of M. oleifera extracts against fungi isolated from farmed prawns and test the toxicity of the extracts on larvae of Macrobrachium amazonicum. The ethanol extracts of pods, seeds, leaves, stems and flowers and chloroform extract of flowers of M. oleifera were tested against 14 strains of Candida spp. and 10 strains of Hortaea werneckii isolated from farming water and the digestive tract of M. amazonicum. Antifungal activity was determined by microdilution, based on the M27-A3 and M38-A2 CLSI documents. Toxicity was evaluated by exposing larvae of M. amazonicum at concentrations between 10-1000mg mL-1, counting dead larvae (CL50) after 24 hours. The best results were verified with the chloroform extract of flowers, acting against all tested strains, with MICs ranging from 0.019 to 2.5 mg mL-1. Ethanol extracts of leaves, flowers and seeds acted against 22/24, 21/24 and 20/24 strains, respectively. The extract of pods was only effective against strains of Candida spp. (14/24) and extract of stem only against four strains of H. werneckii (4/24). Extracts of seeds, flowers (chloroform fraction), stems and leaves showed low or no toxicity, whereas extracts of pods and flowers (ethanol fraction) showed moderate toxicity. Thus, the antifungal activity of these extracts agaisnt Candida spp. and H. werneckii was observed, a wide margin of safety for larvae of M. amazonicum, demonstrating to be promising for the sustainable management of effluents from M. amazonicum farming

As relações genéticas de 105 acessos de diferentes origens geográficas do banco de germoplasma de mangueira da Embrapa foram determinadas com base no marcador AFLP, de forma a orientar trabalhos de melhoramento e manejo de recursos genéticos da espécie para a região Semi-Árida brasileira. Foram ainda incluídos dois acessos de duas espécies do gênero Mangifera, como "outgroup". O DNA dos acessos foi extraído pelo método do CTAB, as reações de AFLP foram realizadas para os iniciadores EcoRI/MseI e as bandas polimórficas foram analisadas para construção de fenograma, baseando-se no coeficiente de similaridade de Jaccard. Foram obtidas 157 e 54 bandas de AFLP polimórficas e monomórficas, respectivamente, em 13 combinações de iniciadores. O valor co-fenético do fenograma foi estimado em 0,81. Foram observados cinco grupos: 1) cultivares como Amrapali, Malika, híbridos Embrapa-Cpac e algumas variedades americanas formando um grupo; 2) grupo formado, predominantemente, por cultivares americanas, com algumas inclusões de híbridos sul-africanos e brasileiros; 3) grande grupo formado por cultivares brasileiras, com algumas inclusões de cultivares australianas, indianas e americanas; 4) grupo formado por algumas variedades tipo Espada, Rosa e acessos de diferentes origens; e 5) grupo formado por M. foetida e M. similis. Os acessos Carabao e Manilla apresentaram a maior similaridade, 97%. Os acessos estudados apresentaram similaridade superior a 51%, evidenciando a alta variabilidade genética da coleção de germoplasma de mangueira estudada.

The genetic relationship among 105 mango accessions of different geographic origins of the Embrapa germplasm collection was estimated based on AFLP marker in order to orient breeding and management of genetic resource activities of this species to the Brazilian Semi-Arid region. Two additional accessions of other species of the Mangifera genus were also included as outgroup. The DNA of the accessions was extracted according to the CTAB protocol, the AFLP reactions were performed to EcoRI/MseI primers and the polymorphic bands analyzed to built a phenogram based on the Jaccard similarity coefficient. A hundred and fifty-seven and fifty-four polymorphic and monomorphic bands, respectively, were obtained from 13 AFLP primer combinations. The phenogram cophenetic value was estimated in 0.81. Five groups were observed: 1) Amrapali, Malika, Embrapa-CPAC hybrids and some American varieties forming a group, 2) other built, predominantly, by American varieties, with some inclusions of South African and Brazilian hybrids, 3) a large group composed by Brazilian accessions, with some inclusion of Australian, Indian and American accessions, 4) a group with some accessions of Espada, Rosa and others of different origins, and 5) a group formed by M. foetida and M. similis. Carabao and Manilla presented the largest similarity, 97%. The studied accessions presented similarity greater than 51%, suggesting a high genetic variability of the studied mango germplasm collection.
