OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

Resumo O estudo objetivou analisar os princípios táticos fundamentais ofensivos e a eficácia técnica de escolares praticantes de futsal. Participaram do estudo 33 alunos de uma escola no Paraná. Utilizou-se o Sistema de Avaliação Tática no Futebol (FUT-SAT) e o Sistema de Análise Notacional em Jogos Reduzidos de Futebol para análise tático-técnica. Constatou-se que o princípio tático “cobertura ofensiva” foi executado com mais frequência pelos escolares praticantes de futsal (p = 0,01) seguido pelo princípio “espaço sem bola” (p < 0,01). Correlações significativas moderadas e fortes foram identificadas entre a frequência de execução dos princípios táticos fundamentais “penetração”, “cobertura ofensiva”, “espaço com bola”, “unidade ofensiva” e a eficiência em habilidades técnicas (de r = 0,43 a r = 0,82, p < 0,05). Conclui-se que no grupo etário avaliado, existe um modelo de jogar próximo ao centro de jogo e que a eficiência de execução técnica está associada com o comportamento tático em situação de jogo.

Abstract The study aimed to analyze the core tactical offensive principles and technical efficiency of primary school futsal players. Thirty-three students from a school in Paraná participated in the study. The System of Tactical Assessment in Soccer (FUT-SAT) and the System of Notational Analysis in Small-sided Soccer Games were used for tactical-technical analysis. It was found that the tactical principle “offensive coverage" was most frequently executed by the primary school futsal players (p = 0.01), followed by "width and length" without ball (p < 0.01). Moderate and strong significant correlations were identified between the execution frequency of the core tactical principles “penetration”, “offensive coverage”, “width and length without ball”, “offensive unity” and efficiency in technical skills (from r = 0.43 to r = 0.82, p < 0.05). It is concluded that there is a model of playing near the game center in the presented age group, and that the efficiency of executing technical skills is associated with tactical behavior in game situation.

Resumo Este trabalho emprega o método comparativo com o objetivo de elucidar o desenvolvimento histórico da fonologia segmental do Paunaka, uma língua Aruaque da Bolívia. Embora o inventário vocálico do Paunaka tenha apenas uma vogal posterior arredondada, é relativamente simples mostrar que o mesmo se deriva de um inventário com duas qualidades vocálicas posteriores arredondadas, *u e *o, mas que o primeiro desses segmentos se tornou uma vogal central não arredondada ɨ. O Paunaka perdeu *r em todos os contextos, um fato que em si sugere que formas contendo r sejam empréstimos com entrada na língua em data posterior a essa mudança. O Paunaka foi sujeito a fricativização de *ts, que, assim, têm reflexos idênticos aos de *s. Embora o Paunaka e o Proto-Mojeño apresentem a coronalização *k > s, a maior parte dos desenvolvimentos fonológicos do Paunaka são recorrentes em diversas línguas da família ou possuem apenas uma similaridade superficial com desenvolvimentos ocorridos em outras línguas, não sendo, portanto, muito relevantes para o estabelecimento de uma classificação interna. Por fim, é apresentado no Apêndice um conjunto de etimologias contendo cognatos no Proto-Mojeño e no Terena de 105 morfemas lexicais e gramaticais do Paunaka.

Abstract This paper applies the comparative method to unravel the historical development of the segmental phonology of Paunaka, an Arawakan language of Bolivia. Although the Paunaka vowel system features a single back rounded vowel, it is rather simple to show that it derives from a system with two back rounded qualities *u and *o, but that the former segment shifted to a high central unrounded vowel ɨ. The language has lost *r unconditionally, implying that Paunaka items with r are probable loanwords. Paunaka underewent a spirantization of *ts, thus merging this affricate with the fricative *s. Although Paunaka shares a coronalization of *k > s with Proto-Mojeño, most of the phonological developments that affected Paunaka are either recurrent in the Arawakan language family or only superficially similar to developments in related languages, and thus provide little weight as evidence for subgrouping. An Appendix is also included, with 105 etymologies matching Paunaka lexical and grammatical morphemes with their cognates in Proto-Mojeño, the two extant Mojeño dialects (Ignaciano and Trinitario) and Terena.

RESUMO O objetivo deste estudo foi analisar os fatores associados à satisfação sexual pós-lesão medular. Oitenta homens com lesão medular compuseram a amostra. Utilizou-se um instrumento semiestruturado sobre prática de atividade física pós-lesão, frequência sexual semanal e satisfação sexual antes e após a lesão, além das características sociodemográficas e da lesão. Para análise estatística utilizaram-se os programas SPSS versão 20.0 e o R versão 3.3.1, considerando um nível de significância de 5%. Inicialmente, empregou-se a análise descritiva por meio de frequências relativas e absolutas. A correlação de Spearman foi utilizada para analisar a magnitude da associação entre as variáveis independentes (frequência sexual semanal, idade, nível de escolaridade, tempo de lesão) com o nível de satisfação após a lesão. Verificou-se a associação entre satisfação sexual e a prática de atividade física, tipo de lesão e parceiro sexual estável por meio da correlação policórica. Constatou-se que a satisfação sexual diminui após a lesão (p<0.001), havendo associação entre o nível de satisfação sexual após lesão com o tempo de lesão (r=0,28, ρ=0,01) e frequência sexual semanal (r=0,25, ρ=0,02) e com parceiras sexuais estáveis (r=0,26, ρ=0,01). Concluiu-se que a satisfação sexual é afetada pela lesão medular, associando-se de forma positiva com o tempo de lesão, frequência sexual e com presença de parceiros sexuais estáveis após a lesão. Sugerem-se novos estudos com classificações baseadas na escala ASIA.

ABSTRACT The aim of the study was to analyze the factors associated with sexual satisfaction after spinal cord injury. Eighty men with spinal cord injury composed the sample. We used a semi-structured questionnaire on the practice of post-injury physical activity, weekly sexual frequency and sexual satisfaction before and after the cord injury, besides the characteristics of the injury and the sociodemographic ones. The programs SPSS (version 20.0) and R (version 3.3.1) were used for statistical analysis, respecting the range of 5%. Initially, we used the descriptive analysis through absolute and relative frequencies. The Spearman correlation was used to analyze the magnitude of the association between the independent variables (weekly sexual frequency, age, education level and injury time) and the sexual satisfaction level after the injury. The association between sexual satisfaction and physical activity, and type of injury and stable sexual partner was verified by the Policoric test. We observed that the satisfaction level decreased significantly after the injury (p<0.001), and also an association between the level of sexual satisfaction after injury and its time (r=0.28, ρ =0.01) and weekly sexual frequency (r=0.25, ρ=0.02) with stable sexual partners (r=0.26, ρ=0.01). The conclusions point that sexual satisfaction is affected by spinal cord injury, associating positively with the injury time, sexual frequency and presence of stable sexual partners after injury. New studies based on the ASIA scale ratings are suggested.

RESUMEN El objetivo de este estudio fue analizar los factores asociados a la satisfacción sexual después de la lesión medular. Un total de 80 hombres con lesión medular compusieron la muestra. Se utilizó un instrumento semiestructurado sobre práctica de actividad física después de la lesión, frecuencia sexual semanal y satisfacción sexual antes y después de la lesión, además de las características sociodemográficas y de la lesión. Para el análisis estadístico, se utilizaron los programas SPSS versión 20.0 y R versión 3.3.1, considerándose un nivel de significancia del 5%. Inicialmente, se llevó a cabo el análisis descriptivo mediante frecuencias relativas y absolutas. Se utilizó la correlación de Spearman para analizar la magnitud de la asociación entre las variables independientes (frecuencia sexual semanal, edad, nivel de escolaridad, tiempo de lesión) con el nivel de satisfacción después de la lesión. Se verificó la asociación entre satisfacción sexual, práctica de actividad física, tipo de lesión y pareja sexual estable por medio de la correlación policórica. Se constató que la satisfacción sexual disminuye después de la lesión (p<0.001), con asociación entre el nivel de satisfacción sexual después de la lesión con el tiempo de lesión (r=0.28, ρ=0.01), frecuencia sexual semanal (r=0.25, ρ=0.02) y con parejas sexuales estables (r=0.26, ρ=0.01). Se concluye que la satisfacción sexual es afectada por la lesión medular, asociándose de forma positiva con el tiempo de lesión, frecuencia sexual y con presencia de parejas sexuales estables después de la lesión. Se sugieren nuevos estudios con clasificaciones basadas en la escala ASIA.

RESUMO Objetivou-se avaliar a capacidade combinatória de linhagens de pimentão, identificar combinações híbridas superiores quanto à produtividade e qualidade de frutos e inferir sobre os modos de ação gênica envolvidos na expressão dos caracteres agronômicos de importância econômica. Para isso, cinco linhagens de pimentão do Projeto Melhoramento Genético de Solanáceas Para Sistema de Cultivo, da Universidade Federal Rural de Pernambuco foram cruzadas, em um esquema dialélico parcial, com dois híbridos simples: Atlantis (ATL) e Valdor (VAL), utilizados como testadores. As linhagens, bem como os híbridos utilizados, foram escolhidas em função de apresentarem características morfológicas divergentes, tais como: formato, comprimento e diâmetro do fruto, espessura da polpa e produtividade. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, vinte tratamentos, constituídos pelas cinco linhagens, dois testadores, dez híbridos experimentais e três híbridos comerciais como testemunhas, os quais foram analisados através do método 2 do modelo I de Griffing, adaptado por Geraldi & Miranda Filho (1988). Detectou-se suficiente variabilidade genética a ser explorada nos componentes do dialelo para a maioria dos caracteres; os efeitos aditivos e não-aditivos foram importantes e significativos, mostrando o desempenho dos genótipos e sua contribuição para a produção de híbridos superiores, as linhagens L1B, L6 e L7 e o testador Valdor destacaram-se como bons combinadores por apresentarem maior capacidade geral de combinação para a maioria dos caracteres agronômicos; o híbrido triplo L1B x VAL destacou-se pelo melhor desempenho, com as melhores capacidades específicas de combinação.

RESUMO Objetivou-se avaliar dois sistemas de poda em genótipos de pimentão hidropônico visando maiores produtividade e qualidade de frutos. Foi utilizado o delineamento em blocos casualizados, três repetições e tratamentos arranjados em parcelas subdivididas. As parcelas corresponderam aos dois sistemas de poda 1-2-4-N e 1-2-4 e as subparcelas aos genótipos de pimentão. O primeiro sistema de poda consistiu em deixar uma haste seguida de duas brotações e mais duas brotações de cada uma destas hastes, de modo a ter a princípio uma haste, depois duas e finalmente quatro. Após a formação de quatro hastes deixou-se o livre crescimento com o número indeterminado de hastes. O segundo diferenciou-se do primeiro por não permitir o crescimento livre e manter continuamente o desenvolvimento da planta com apenas quatro hastes. A parcela experimental foi constituída por três plantas. Os dados coletados foram submetidos à análise da variância e as médias comparadas pelo teste de Scott-Knott a 5% de significância. Os híbridos apresentaram características agronômicas satisfatórias, sendo os híbridos simples Valdor (98,39 t/ha) e o híbrido triplo L6 X VAL (92,46 t/ha) os mais produtivos. Os sistemas de poda interferiram no desempenho do pimentão para os caracteres relação comprimento/diâmetro do fruto, número de lóculos, número de frutos por planta e produtividade total. Recomenda-se o sistema de poda 1-2-4-N (78,32 t/ha) por representar maior facilidade na condução das plantas e redução nos custos com mão-de-obra, tornando-se o sistema de maior produtividade e viabilidade aos produtores de pimentão em cultivo protegido e hidropônico comparado ao sistema 1-2-4 de produtividade de 68,60 t/ha.

ABSTRACT The objective was to evaluate two pruning systems in sweet pepper genotypes under hydroponic cultivation, aiming higher productivity and fruit quality. The experimental design was randomized blocks with three replications, treatments being arranged in split plots. Plots corresponded to two pruning systems (1-2-4-N and 1-2-4) and subplots corresponded to the genotypes evaluated. The first pruning system consisted of leaving the first branch with two branches and the second branch with four branches and, after that, the plant was allowed to grow freely. The second pruning treatment differed from the first one, limiting the free growing of the plant after pruning. The experimental plots consisted of three pots, one plant per pot. Data were submitted to analysis of variance (ANOVA) and compared by Scott Knott 5%. Hybrids presented satisfying agronomic characteristics, and the simple hybrid Valdor (98.39 t/ha) and the triple hybrid L6 X VAL (92.46 t/ha) were the most productive ones. The pruning systems affected sweet pepper traits, namely diameter/length ratio of fruits, number of locules, number of fruits per plant, and total yield. The 1-2-4-N (78.32 t/ha) pruning system is the most viable for local sweet pepper producers considering its simplicity and the cost reduction in labor. This system is more yielding in greenhouse and hydroponics, compared to the system 1-2-4 producing 68.60 t/ha.

Abstract: En | Text: En | PDF: En

With the urbanisation of the population in developing countries and the process of globalisation, Chagas has become an emerging disease in the urban areas of endemic and non-endemic countries. In 2006, it was estimated that the prevalence of Chagas disease among the general Bolivian population was 6.8%. The aim of the present study was to determine the prevalence of Trypanosoma cruzi infection among Bolivian immigrants living in São Paulo, Brazil. This study had a sample of 633 volunteers who were randomly selected from the clientele of primary care units located in the central districts of São Paulo, Brazil. Infection was detected by two different ELISA assays with epimastigote antigens, followed by an immunoblot with trypomastigote antigens as a confirmatory test. The prevalence of the infection was 4.4%. Risk factors independently associated with the infection were: a history of rural jobs in Bolivia, knowledge of the vector involved in transmission, and having relatives with Chagas disease. Brazil has successfully eliminated household vector transmission of T. cruzi, as well as its transmission by blood transfusion. The arrival of infected immigrants represents an additional challenge to primary care clinics to manage chronic Chagas disease, its vertical transmission, and the blood derivatives and organ transplant programs.

Abstract: En | Text: En | PDF: En

Composite resin and metallic posts are the materials most employed for reconstruction of teeth presenting partial or total destruction of crowns. Resin-based cements have been widely used for cementation of ceramic crowns. The success of cementation depends on the achievement of adequate cement curing. Objectives: To evaluate the microhardness of Variolink® II (Ivoclar Vivadent, Schaan, Liechtenstein), used for cementing ceramic crowns onto three different coronal substrate preparations (dentin, metal, and composite resin), after 7 days and 3 months of water storage. The evaluation was performed along the cement line in the cervical, medium and occlusal thirds on the buccal and lingual aspects, and on the occlusal surface. Material and Methods: Thirty molars were distributed in three groups (N=10) according to the type of coronal substrate: Group D- the prepared surfaces were kept in dentin; Groups M (metal) and R (resin)- the crowns were sectioned at the level of the cementoenamel junction and restored with metallic cast posts or resin build-up cores, respectively. The crowns were fabricated in ceramic IPS e.max® Press (Ivoclar Vivadent, Schaan, Liechtenstein) and luted with Variolink II. After 7 days of water storage, 5 specimens of each group were sectioned in buccolingual direction for microhardness measurements. The other specimens (N=5) were kept stored in deionized water at 37ºC for three months, followed by sectioning and microhardness measurements. Results: Data were first analyzed by three-way ANOVA that did not reveal significant differences between thirds and occlusal surface (p=0.231). Two-way ANOVA showed significant effect of substrates (p<0.001) and the Tukey test revealed that microhardness was significantly lower when crowns were cemented on resin cores and tested after 7 days of water storage (p=0.007). Conclusion: The type of material employed for coronal reconstruction of preparations for prosthetic purposes may influence the cement properties.

The following hypothesis was tested: direct composites additional polymerization improve the surface microhardness of direct composite resin Filtek Z250 (3M ESPE). We prepared 25 specimens (2x4 mm) with a stainless steel mold. Resin specimens were randomly assigned into 5 groups (n=5/per group): G1 - resin Filtek Z250 photoactivated 60 s; G2 - resin Filtek Z250 photoactivated 60 s + autoclave cycle to 134°C for 7 min at a pressure of 2.5 kg/cm3; G3 - resin Filtek Z250 photoactivated 60 s + oven at 125°C for 7 min; G4 - resin Filtek Z250 photoactivated 60 s + microwave for 3 min to the power of 450W; G5 - indirect resin Resilab photoactivated 60 s + supplementary furnace LUX GDS 4 min. The specimens were fabricated by a metal matrix, filled with resin in two increments and each increment polymerized according to their group. For polymerization of the last layer, we used a glass plate on a polyester strip. Then the specimens were evaluated for surface microhardness Knoop. Additional polymerization media resulted in significant differences among the groups (p<0.05) (One-way ANOVA and Dunnett test, p=0.05). The mean surface hardness Knoop (KHM) were as follows: G1: 51.71+1.73b; G2: 62.37+1.71a; G3: 50.61+1.30b; G4: 52.65+1.125b; G5: 60.15+2.02a; Conclude that the additional polymerization in autoclave increased the surface microhardness Knoop of composite resin evaluated. Hypothesis was partially confirmed.

La siguiente hipótesis fue probada: evaluar si la polimerización mejora aún más la dureza de la superficie de la resina compuesta directa Filtek Z250 (3M ESPE). Se prepararon 25 muestras (2x4mm) de un molde de acero inoxidable. Las muestras de resina fueron divididas al azar en 5 grupos (n = 5): G1-resina Filtek Z250 polimerizado durante 60 s; G2-polimerizado la resina Filtek Z250 durante 60 s y ciclo de autoclave 134°C durante 7 min. a una presión de 2,5 kg/ cm3; G3-resina Filtek Z250 polimerizado durante 60 s y cura para el horno a 125°C durante 7 min; G4-resina Filtek Z250 polimerizado por 60 s y curada durante 3 min. con una potencia de microondas de 450W; G5-resina indirecta (Resilab) polimerizado 60 s y curada horno LUX/GDS durante 4 min. Las muestras fueron fabricadas por una matriz metálica, rellena con resina en dos incrementos, y cada incremento de polimerizado de acuerdo a su grupo. Para la polimerización de la última capa se utilizó una placa de vidrio y una tira de poliéster. Luego se evaluó la microdureza Knoop de la superficie de las muestras. La polimerización adicional resultó en diferencias significativas entre los grupos (p <0,05) (One-way ANOVA y prueba de Dunnett, p = 0,05). La dureza media de la superficie (KHM) fue: G1: 51,71+1,73b, G2: 62,37+1,71a; G3: 50,61+1,30b, G4: 52,65+1,125b; G5: 60,15+2,02³. Se concluye que la polimerización adicional con autoclave aumentó la microdureza de la superficie de resina evaluada. La hipótesis fue confirmada parcialmente.

Abstract: En | Text: En | PDF: En

The leishmaniases are severe parasitic diseases that occur worldwide, caused by protozoa of the genus Leishmania. Studies with medicinal plants can lead to a range of possibilities for treating and improving the patients' quality of life. Research on Azadirachta indica fractions and extracts has shown that they have excellent anti-leishmanial activity based on bioactivity-guided fractionation of ethanolic extracts of leaves and seeds and in vitro activity against promastigotes. In this research the most efficient extracts and fractions were selected for tests on intracellular amastigotes of Leishmania amazonensis. The ethanolic extract of the leaves and dichloromethane and chloroform fractions had IC50 values of 38, 3.9 and 1.2 μg/mL for promastigotes and 9.8, 1.1 and 0.6 μg/mL for amastigotes, respectively, at 72 hours. For the ethanolic extract and dichloromethane fraction from nut tegument, the IC50 was 2.7 and 2.1 μg/mL for promastigotes and 0.4 and 0.6 μg/mL for amastigotes. The cytotoxicity of the fractions presented selectivity that was between 8 to 32 times more toxic to promastigotes and 15 to 72 times to amastigotes than to macrophages. The extracts and fractions from leaves and fruits were more effective against amastigotes, and the fractionation increased activity against both promastigotes and amastigotes, enabling us to obtain potentially active fractions with low toxicity.

Abstract: En | Text: En | PDF: En

New records of Hemigrammus ora Zarske, Le Bail & Géry, 2006, previously believed to be endemic to the French Guiana drainages, are confirmed for Brazilian drainages. The species is reported from the Tocantins-Araguaia system and lower Amazon River. Morphometric and meristic data, previously undescribed morphological traits related to caudal-fin squamation and anal-fin hooks, and geographic variation are presented for the species.

Moenkhausia dasalmas é descrita da bacia do alto rio Tocantins, Chapada dos Veadeiros, Goiás, Brasil Central. A espécie nova difere de todas as suas congêneres pela presença de iii,9 raios na nadadeira dorsal. Ela também se distingue das suas congêneres por apresentar duas manchas umerais (a primeira verticalmente alongada e a segunda tênue), 17-19 raios ramificados na nadadeira anal, 36-37 escamas na linha lateral, quatro a cinco dentes no maxilar e uma mancha vertical e escura no final do pedúnculo caudal.

Moenkhausia dasalmas is described from the upper rio Tocantins basin, in the Chapada dos Veadeiros region, Goiás State, Central Brazil. The new species differs from all congeners by the presence of iii,9 rays in the dorsal fin. It can also be distinguished from its congeners by the presence of two humeral spots (first one vertically elongate and second one faint), by the number of branched anal-fin rays (17-19), lateral line scales (36-37), maxillary teeth (4-5), and a vertical dark spot in the caudal peduncle end.

Hasemania kalunga é descrita para a bacia do alto rio Tocantins, Chapada dos Veadeiros, Goiás, Brasil. A espécie nova distingue-se das suas congêneres pelo número de escamas perfuradas da linha lateral (11-21 vs. 5-9, exceto de H. crenuchoides e H. piatan), pela presença de uma mancha umeral preta e verticalmente alongada (vs. ausência, exceto de H. crenuchoides, H. nambiquara e H. piatan), e pela ausência de escamas na base da nadadeira anal (vs. presença, exceto de H. maxillaris e H. piatan), por 19 raios principais na nadadeira caudal (vs.18 em H. piatan). Ela também difere de H. crenuchoides por dados morfométricos.A ausência de uma bainha de escamas cobrindo a base da nadadeira anal, um caráter incomum em Characidae, e o endemismo da ictiofauna do alto rio Tocantins são discutidos.

Hasemania kalunga is described from the upper rio Tocantins basin, Chapada dos Veadeiros, Goiás State, Brazil. The new species is distinguished from its congeners by the number of perforated lateral line scales (11-21 vs. 5-9, except from H. crenuchoides and H. piatan), by the presence of a black ver tically-elongate humeral spot (vs. absent, except from H. crenuchoides, H. nambiquara, and H. piatan), and by absence of scale sheath along anal-fin base (vs. presence, except from H. maxillaris, and H. piatan), by 19 principal caudal-fin rays (vs. 18 in H. piatan). It differs also from H. crenuchoides by morphometric data. The absence of scale sheath covering the anal-fin base, an uncommon character in Characidae, and the endemism of the ichthyofauna from the upper rio Tocantins are discussed.

Astyanax goyanensis (Miranda-Ribeiro, 1944), nova combinação, é redescrita com base na série-tipo e topótipos, e A. courensis, espécie nova, é descrita. Ambas espécies foram coletadas na bacia do rio dos Couros, bacia do alto rio Tocantins, Chapada dos Veadeiros, Goiás, Brasil. Estes táxons possuem os caracteres e morfologia do corpo das espécies do complexo Astyanax scabripinnis. A transferência e nova combinação de Astyanax goyanensis devem-se a ausência de caracteres que definem Astyanacinus. Astyanax goyanensis e A. courensis diferem das congêneres por caracteres merísticos, morfométricos e padrão de colorido. Astyanax goyanensis possui apenas sete raios na nadadeira pélvica, caráter incomum nas espécies do gênero, e A. courensis possui apenas três ou quatro séries de escamas abaixo da linha lateral, menos do que típico do gênero.

Astyanax goyanensis (Miranda-Ribeiro, 1944), new combination, is redescribed based on the type series and topotypes, and A. courensis, new species, is herein described. Both species were collected in the rio dos Couros basin, upper rio Tocantins basin, Chapada dos Veadeiros, Goiás State, Brazil. These species possess the characters and general body morphology of the species of the Astyanax scabripinnis species complex. The new combination of Astyanax goyanensis is supported by the absence of characters that define Astyanacinus. Astyanax goyanensis and A. courensis differ from their congeners by meristic and morphometric characters, and color pattern. Astyanax goyanensis has only seven pelvic-fin rays, an uncommon character in the species of this genus, and A. courensis possesses only three or four scale rows below the lateral-line, fewer than typical of the genus.
