Abstract: En Pt | Text: En Pt | PDF: En | PDF: Pt

Abstract Erythema multiforme is a mucocutaneous disease characterized by the acute appearance of blisters and ulcers, with or without oral involvement. In this report, a 12-year-old female patient presented with extensive ulcerative lesions on the upper and lower lips, with painful symptoms and areas of bleeding and suppuration. Despite these lesions being restricted to the lips and skin around, the patient was diagnosed with erythema multiforme. Dexamethasone was then prescribed, in addition to the use of lip balm. At the first return evaluation, there was no regression of the clinical picture, and the medication was replaced by prednisone, associated with amoxicillin and 0.12% chlorhexidine mouthwash. In the second return visit, there was considerable regression of the lesion, and the process of gradual discontinuation of the corticosteroid was initiated. After 1 week, the lesions had healed, and the drug was discontinued. The oral cavity may be the only site affected by erythema multiforme, so knowledge of this disease is necessary for its correct diagnosis and treatment.

Resumo O eritema multiforme é uma doença mucocutânea, caracterizada pela ocorrência súbita de bolhas e úlceras, com ou sem envolvimento da cavidade oral. No presente relato, uma paciente do sexo feminino, com 12 anos de idade, apresentou lesões ulceradas extensas nos lábios, superior e inferior, acompanhadas de sintomas dolorosos, zonas de hemorragia e supuração. Embora essas lesões estivessem localizadas apenas nos lábios e na pele circundante, a paciente recebeu o diagnóstico de eritema multiforme. Foi então prescrita dexametasona, juntamente com a indicação de protetor labial. Na primeira avaliação de retorno, não houve regressão do estado clínico, resultando na substituição do medicamento por prednisona, em combinação com amoxicilina e colutório de clorexidina a 0,12%. Na segunda consulta de acompanhamento, houve regressão considerável da lesão, iniciando-se, assim, o processo gradual de suspensão do corticosteroide. Após 1 semana, as lesões cicatrizaram e o medicamento foi interrompido. A cavidade oral pode ser o único local afetado pelo eritema multiforme, sendo necessário o conhecimento dessa doença para o seu correto diagnóstico e tratamento.

Resumen Introducción: El Pacífico Norte de Costa Rica es una región diversa y productiva; sin embargo, tenemos un escaso conocimiento sobre el estado de los recursos marinos y la dinámica pesquera, particularmente de la pesca artesanal en el Golfo de Santa Elena, uno de los principales caladeros de la zona. Objetivo: Caracterizar la dinámica de esta pesquería. Métodos: Se analizaron los datos recopilados por el Instituto Costarricense de Pesca y Acuicultura y las facturas pesqueras de los sitios de desembarque para el período 2010-2019. Resultados: Hubo una alta variación en la biomasa desembarcada, sin embargo, la captura total por unidad de esfuerzo (CPUE; kg/día) y de las principales especies objetivo no disminuyó significativamente. En general, hubo una CPUE más baja en los meses de surgencia (diciembre-abril). De las 42 especies comerciales reportadas, la mayor biomasa provino del pargo mancha (Lutjanus guttatus; 22 % de la biomasa), el pargo seda (L. peru; 18 %), las cabrillas (Epinephelus spp.; 15 %) y el pulpo (Octopus spp., 13 %). Conclusiones: La CPUE en Santa Elena no ha disminuido significativamente de 2010 a 2019, pero disminuye en la época de surgencia.

Abstract Introduction: The North Pacific of Costa Rica is a diverse and productive region; however, we have a poor understanding of the status of marine resources and fisheries dynamics, particularly for the artisanal fishery in the Gulf of Santa Elena, one of the main fishing grounds of the area. Objective: To characterize the dynamics of this fishery. Methods: We analyzed data collected by the Instituto Costarricense de Pesca y Acuicultura, and sales invoices from landing sites for the period 2010-2019. Results: There was high variation in the landed biomass, however, total catch per unit effort (CPUE; kg/day) and of the main targeted species did not decrease significantly. Overall, there was a lower CPUE in upwelling months (December-April). For the 42 commercial species reported, most biomass was from the spotted rose snapper (Lutjanus guttatus; 22 % of biomass), the Pacific red snapper (L. peru; 18 %), groupers (Epinephelus spp.; 15 %) and octopuses (Octopus spp., 13 %). Conclusions: CPUE at Santa Elena has not declined significantly from 2010 to 2019, but it falls in the upwelling season.

Resumen Introducción: La naturaleza tropical está experimentando una amenaza sin precedentes que incluye comunidades de peces costeros que requieren un constante seguimiento de la presencia de especies. El uso simultáneo de varios métodos de monitoreo debería reducir el sesgo causado por la selectividad de cada método. Objetivo: Este estudio uso cuatro diferentes métodos de muestreo a lo largo de dos años para evaluar y comparar los ensamblajes de peces en el Área Marina de Manejo Bahía Santa Elena, Pacífico de Costa Rica. Métodos: Examinamos los cambios en la riqueza y composición de especies entre épocas de afloramiento y no afloramiento entre julio de 2019 y febrero de 2020. Aplicamos censos visuales, cámaras remotas submarinas; líneas de fondo; y pesca deportiva. Resultados: Identificamos 140 especies de peces (54 familias); las cámaras submarinas remotas detectaron el 83 %, seguido por los censos visuales submarinos (65 %), la pesca deportiva (16 %) y las líneas de fondo (14 %). Solo el método de pesca deportiva detectó diferencias en la riqueza y composición de especies entre temporadas. Conclusión: Las cámaras remotas parecen ser el mejor método para el conteo de especies y la pesca deportiva para detectar diferencias estacionales en las costas tropicales similares a la aquí estudiada.

Abstract Introduction: Tropical nature is experiencing an unprecedented threat that includes coastal fish communities that requires a close monitoring of species presence. The simultaneous use of several monitoring methods should reduce the bias caused by the selectivity of each method. Objective: This study used four different sampling methods over two years to assess and compare fish assemblages in the Santa Elena Bay Marine Management Area (AMM-BSE), North Pacific of Costa Rica. Methods: We examined changes in species richness and composition between upwelling and non-upwelling seasons from July 2019 and February 2020. We applied visual censuses, underwater remote cameras; bottom lines; and sport fishing. Results: We identified 140 species of fish (54 families); remote underwater cameras detected 83 %, followed by underwater visual censuses (65 %), sport-fishing (16 %) and bottom lines (14 %). Only the sport-fishing method detected differences in species richness and composition between seasons. Conclusion: Remote cameras appear to be the best method for species counts, and sport-fishing to detect seasonal differences in tropical coasts similar to the one studied here.

Resumen Se realizó un estudio bibliométrico y un análisis detallado de las diversas variables de los proyectos finales de graduación de grado realizados en la carrera de Geografía de la Universidad de Costa Rica (UCR) y un análisis estadístico de las diversas variables de tales trabajos. Esta investigación responde a la necesidad de cuantificar y analizar las distintas aristas de la producción científica del estudiantado de la carrera del mencionado programa, lo que no se había hecho hasta el momento. El fin de la publicación es divulgar los resultados encontrados para visibilizar y demostrar la eficiencia y utilidad de estas investigaciones al programa. De igual manera, y para instar a sus dirigentes y docentes a fortalecer aquellos aspectos aún débiles e impulsar y dirigir esfuerzos hacia temas de actualidad no abordados hasta el momento y que atiendan las necesidades de contexto. La metodología incluyó la revisión documental y la consulta a la base de datos del Sistema de Bibliotecas y Documentación e Información de la Universidad de Costa Rica (SIBDI). De dicha base se extrajeron datos que fueron procesados con las herramientas de Libreoffice y QGIS. El resultado más importante reside en el desarrollo de 141 trabajos finales de graduación realizados en la Escuela de Geografía-UCR desde 1966 hasta el 2021, para un promedio anual de 2.6, los cuales no solo han consistido en un requisito académico, sino que muchos de ellos han sido insumo para la atención de problemas nacionales e internacionales.

Abstract The authors carried out a bibliometric study and a detailed analysis of the various variables of the final graduation projects developed in the Geography Career of the University of Costa Rica (UCR). This research responds to the need to quantify and analyze the different aspects of the scientific production of the student body, which had not been done exhaustively until now. The purpose of the publication is to disclose the results found, to make visible and demonstrate the efficiency and usefulness of these investigations. Similarly, it urges their leaders to strengthen those weak aspects and promote current issues and address the needs of the context. The basic methodological steps focused on document reviewed and consulted from the database of the System of Libraries and Documentation of the University of Costa Rica (SIBDI). Data were extracted from this base and processed with the tools of the Libreoffice and QGIS software. One of the most relevant results is that the School of Geography-UCR has supported the development of 141 final graduation projects from 1966 to 2021, for an annual average of 2.6, which have not only consisted on an academic requirement, but many of them have been input for the attention of national and international problems.

Resumo O fibroblastoma desmoplásico (FD) é um tumor benigno raro de partes moles de origem fibroblástica e miofibroblástica e sua ocorrência na cavidade oral é rara. Este estudo detalha um novo caso de uma lesão elevada no rebordo alveolar de uma mulher de 59 anos, dolorosa à mastigação. O exame histopatológico mostrou proliferação de células de morfologia fusiformes a estreladas, não encapsulada, em um estroma rico em colagénio e hipocelular. As células tumorais foram forte e difusamente positivas para vimentina e algumas células foram focalmente positivas para α-actina do músculo liso, CD99 e β-catenina. Os exames foram conclusivos para o diagnóstico de FD. O paciente está no período de acompanhamento e nenhuma lesão recorrente foi detetada em um ano. O FD descrito neste relato, apesar de apresentar características clínico-patológicas-imuno-histoquímicas semelhantes aos casos descritos anteriormente, é apresentado em um local oral incomum e associado a sintomatologia dolorosa. A imuno-histoquímica é uma ferramenta importante nos casos de FD nos quais o exame histopatológico não é conclusivo.

Abstract The desmoplastic fibroblastoma (DF) is a rare benign soft-tissue tumor of fibroblastic and myofibroblastic origin, and its occurrence in the oral cavity is rare. This study details a new case of an elevated lesion in the alveolar ridge of a 59-year-old woman, painful during mastication. The histopathological exam showed non-encapsulated stellate-to-spindle cells proliferation in a hypocellular collagen-rich stroma. Tumor cells were strongly and diffusely positive for vimentin, and some cells were focally positive for α-smooth muscle actin, CD99, and β-catenin. The exams were conclusive for DF diagnosis. The patient is in the follow-up period, and no recurrent lesions were detected within one year. Despite having similar clinical, pathological, and immunohistochemical features to the cases previously described, the DF in this report is at an unusual oral site and associated with painful symptomatology. Immunohistochemistry is an important tool in DF cases where the histopathological examination is not conclusive.

Abstract Phytochemical studies of Cespedesia spathulata (Ochnaceae) leaves using 1H, 13C NMR, and GC-MS have led to the isolation of some metabolites identified for the first time in these species such as cathechin, epicatechin, vitexin, orientin, 6’’-O-acetyl-vitexin, sitosterol, stigmasterol, phytol, 4,5-dihydrovomifoliol and a mixture of aliphatic methyl esters, together with ochnaflavone, which was previously isolated from this plant. The modulating activity of some fractions and compounds from Cespedesia spathulata towards tyrosinase enzyme was assayed by spectroscopic and theoretical means/experiments. The dichloromethane fraction (133 μg mL-1) and ochnaflavone (333 μM) inhibited tyrosinase activity by 20 % and 2.0 %, respectively, whereas the ethyl acetate fraction (666 μg mL-1) and ±catechins (catechin and epicatechin - 800 μM) activated it by 104 % and 384 %, respectively. Quantum chemical calculations suggested that catechin and epicatechin are better activators than L-DOPA by interacting with Cu (II) ions. Molecular docking results suggested that hydrogen bonding and hydrophobic interactions are the main binding forces between each tyrosinase activator and the amino acid residues inside the active protein binding pocket.

RESUMO O futsal é um esporte que envolve ações motoras de alta intensidade e curta duração, principalmente, saltos verticais e sprints que exigem rápida aplicação de força e velocidade. A avaliação e o treinamento dessas capacidades físicas fazem parte de uma prática rotineira de treinadores, especialmente, das categorias de base, em que há o ingresso de muitas crianças e adolescentes que pretendem seguir uma carreira profissional no futsal. Em relação ao treinamento desse público, a puberdade é um fator que deve ser considerado como um processo biológico natural envolvendo diversas transformações corporais que podem influenciar no desempenho dessas capacidades físicas, principalmente, considerando que as categorias são divididas pela idade cronológica que nem sempre corresponde à idade puberal. O objetivo desse estudo consistiu em realizar uma revisão da literatura em relação às modificações corporais durante a puberdade e como as mesmas podem afetar os aspectos que determinam o bom desempenho em saltos e sprints. Foi verificado que essa fase está associada a alterações hormonais, aumento da massa muscular e aspectos antropométricos, assim como o amadurecimento das funções neuromusculares e refinamento das atividades motoras mais complexas como a locomoção. Juntos, esses fatores podem favorecer a rápida aplicação de força e maior rendimento desses jogadores quanto às atividades motoras. Entretanto, é importante ressaltar que, embora esses fatores aumentem e favoreçam naturalmente o desempenho de força e velocidade dos jogadores, essa é uma fase em que tipos específicos de treinamento focados em aspectos que determinam o bom rendimento são fundamentais para aumentar essas capacidades e diminuir outros aspectos que também podem ocorrer com o desenvolvimento corporal, como por exemplo, a diminuição temporária da coordenação motora e equilíbrio devido ao pico de crescimento e a rigidez tecidual que, algumas vezes, podem ocorrer durante esse período. Nível de evidência V; Opinião de Especialista.

ABSTRACT Futsal is a sport that involves motor actions with high intensity and short duration, especially vertical jumps and sprints, which require fast application of strength and speed. The evaluation and training of these physical capacities is a routine practice of coaches, especially in the base categories, which are the entry point for many children and adolescents aiming for a professional career in futsal. With regard to the training of this public, puberty is a factor that must be considered, as a natural biological process involving several bodily transformations that can influence the performance of these physical capacities, especially considering that the categories are divided by chronological age, which does not always correspond to pubertal age. The objective of this study was to conduct a literature review of body modifications during puberty, and how these can affect the aspects that determine good performance in jumps and sprints. It was verified that this phase is associated with hormonal changes, an increase in muscle mass, and anthropometric aspects, as well as the maturation of the neuromuscular functions and refinement of the more complex motor activities, such as locomotion. Together, these factors can favor the fast application of force, and better performance of these players in terms of motor activities. However, it is important to emphasize that although these factors increase and naturally favor the players' performance in terms of strength and speed, it is a phase in which specific types of training focused on the aspects that determine good performance are fundamental to increase these capacities and diminish other aspects that also occur with the bodily development, such as a transient decrease in motor coordination and balance due to the rapid growth spurt, and tissue stiffness, which can sometimes occur during this period. Level of evidence V; Expert Opinion.

RESUMEN El futsal es un deporte que abarca acciones motoras de alta intensidad y corta duración, principalmente, saltos verticales y sprints, que exigen rápida aplicación de fuerza y velocidad. La evaluación y entrenamiento de estas capacidades físicas forman parte de una práctica rutinaria de entrenadores, especialmente de las categorías de base, en que hay ingreso de muchos niños y adolescentes que pretenden seguir una carrera profesional en el futsal. Con relación al entrenamiento de ese público, la pubertad es un factor que debe ser considerado como un proceso biológico natural involucrando diversas transformaciones corporales que pueden influenciar en el desempeño de esas capacidades físicas, principalmente, considerando que las categorías son divididas por la edad cronológica que no siempre corresponde a la edad puberal. El objetivo de este estudio consistió en realizar una revisión de la literatura con relación a las modificaciones corporales durante la pubertad y cómo pueden las mismas afectar los aspectos que determinan el buen desempeño en saltos y sprints. Se verificó que esta fase está asociada a alteraciones hormonales, aumento de la masa muscular y aspectos antropométricos, así como la madurez de las funciones neuromusculares y refinamiento de las actividades motoras más complejas como la locomoción. Juntos, estos factores pueden favorecer la rápida aplicación de fuerza y mayor rendimiento de estos jugadores cuanto a las actividades motoras. Entretanto, es importante resaltar que, aunque estos factores aumenten y favorezcan naturalmente el desempeño de fuerza y velocidad de los jugadores, esta es una fase en que tipos específicos de entrenamiento enfocados en aspectos que determinan el buen rendimiento son fundamentales para aumentar esas capacidades y disminuir otros aspectos que también pueden ocurrir con el desarrollo corporal, como por ejemplo, la disminución transitoria de la coordinación motora y el equilibrio debido al pico de crecimiento, además de la rigidez tisular que, algunas veces, pueden ocurrir durante ese período. Nivel de evidencia V; Opinión de Especialista.

RESUMO Objetivo: Definir o perfil epidemiológico e os principais determinantes de morbimortalidade dos pacientes cirúrgicos não cardíacos de alto risco no Brasil. Métodos: Estudo prospectivo, observacional e multicêntrico. Todos os pacientes cirúrgicos não cardíacos admitidos nas unidades de terapia intensiva, ou seja, considerados de alto risco, no período de 1 mês, foram avaliados e acompanhados diariamente por, no máximo, 7 dias na unidade de terapia intensiva, para determinação de complicações. As taxas de mortalidade em 28 dias de pós-operatório, na unidade de terapia intensiva e hospitalar foram avaliadas. Resultados: Participaram 29 unidades de terapia intensiva onde foram realizadas cirurgias em 25.500 pacientes, dos quais 904 (3,5%) de alto risco (intervalo de confiança de 95% - IC95% 3,3% - 3,8%), tendo sido incluídos no estudo. Dos pacientes envolvidos, 48,3% eram de unidades de terapia intensiva privadas e 51,7% de públicas. O tempo de internação na unidade de terapia intensiva foi de 2,0 (1,0 - 4,0) dias e hospitalar de 9,5 (5,4 - 18,6) dias. As taxas de complicações foram 29,9% (IC95% 26,4 - 33,7) e mortalidade em 28 dias pós-cirurgia 9,6% (IC95% 7,4 - 12,1). Os fatores independentes de risco para complicações foram Simplified Acute Physiology Score 3 (SAPS 3; razão de chance − RC = 1,02; IC95% 1,01 - 1,03) e Sequential Organ Failure Assessment Score (SOFA) da admissão na unidade de terapia intensiva (RC =1,17; IC95% 1,09 - 1,25), tempo de cirurgia (RC = 1,001; IC95% 1,000 - 1,002) e cirurgias de emergências (RC = 1,93; IC95% 1,10 - 3,38). Em adição, foram associados com mortalidade em 28 dias idade (RC = 1,032; IC95% 1,011 - 1,052) SAPS 3 (RC = 1,041; IC95% 1,107 - 1,279), SOFA (RC = 1,175; IC95% 1,069 - 1,292) e cirurgias emergenciais (RC = 2,509; IC95% 1,040 - 6,051). Conclusão: Pacientes com escores prognósticos mais elevados, idosos, tempo cirúrgico e cirurgias emergenciais estiveram fortemente associados a maior mortalidade em 28 dias e mais complicações durante permanência em unidade de terapia intensiva.

ABSTRACT Objective: To define the epidemiological profile and the main determinants of morbidity and mortality in noncardiac high surgical risk patients in Brazil. Methods: This was a prospective, observational and multicenter study. All noncardiac surgical patients admitted to intensive care units, i.e., those considered high risk, within a 1-month period were evaluated and monitored daily for a maximum of 7 days in the intensive care unit to determine complications. The 28-day postoperative, intensive care unit and hospital mortality rates were evaluated. Results: Twenty-nine intensive care units participated in the study. Surgeries were performed in 25,500 patients, of whom 904 (3.5%) were high-risk (95% confidence interval - 95%CI 3.3% - 3.8%) and were included in the study. Of the participating patients, 48.3% were from private intensive care units, and 51.7% were from public intensive care units. The length of stay in the intensive care unit was 2.0 (1.0 - 4.0) days, and the length of hospital stay was 9.5 (5.4 - 18.6) days. The complication rate was 29.9% (95%CI 26.4 - 33.7), and the 28-day postoperative mortality rate was 9.6% (95%CI 7.4 - 12.1). The independent risk factors for complications were the Simplified Acute Physiology Score 3 (SAPS 3; odds ratio - OR = 1.02; 95%CI 1.01 - 1.03) and Sequential Organ Failure Assessment Score (SOFA) on admission to the intensive care unit (OR = 1.17; 95%CI 1.09 - 1.25), surgical time (OR = 1.001, 95%CI 1.000 - 1.002) and emergency surgeries (OR = 1.93, 95%CI, 1.10 - 3.38). In addition, there were associations with 28-day mortality (OR = 1.032; 95%CI 1.011 - 1.052), SAPS 3 (OR = 1.041; 95%CI 1.107 - 1.279), SOFA (OR = 1.175, 95%CI 1.069 - 1.292) and emergency surgeries (OR = 2.509; 95%CI 1.040 - 6.051). Conclusion: Higher prognostic scores, elderly patients, longer surgical times and emergency surgeries were strongly associated with higher 28-day mortality and more complications during the intensive care unit stay.

Abstract: En | Text: En | PDF: En

Abstract The study identifies the Canastra-3 Kimberlite magnetic anomaly as the likely primary source of the alluvial diamonds recovered by "garimpeiros" in the Santo Antônio River basin (Delfinópolis, southwestern Minas Gerais). This conclusion is based on cumulative geophysical, hydrographic, metallogenical and mineral geochemistry evidences. The study area is located within fertile ground in the border of the São Francisco craton, close to other diamond primary sources and secondary deposits. This kimberlitic target is the only known in the Santo Antônio River basin. In addition, the known mineralized gravels of this river, worked in the past by "garimpeiros", have evidence of a short transport (angular pebbles and blocks), further evidence of a nearby source. The original data collected in the "Minas Gerais Aerogeophysical Survey Program" was processed and analyzed with the Euler Deconvolution method, implemented in software Oasis Montaj. With the exception of the Canastra-3 body anomaly, all others in the study were classified as non-kimberlitic. Recent sampling work on the weathered top of the Canastra-3 Kimberlite recovered indicator minerals, notably a high proportion of pyrope garnets of the G-10 type, which is unusual among the kimberlites of the region.

ABSTRACT Fungi are ubiquitous components of soil microbial communities, generally comprise the largest proportion of soil biomass. They can occur as filamentous forms or unicellular yeasts, in both, as free-living or symbionts. Next generation sequencing has allowed greater depth of the access to soil fungal diversity complementing culture-dependent results. In Brazil, the state of Minas Gerais is recognized for its mining activity, which modifies the vegetation cover and consequently the soil microbial communities. To describe the fungal community (total fungi and yeast) in a post-mining area, comparing natural and modified ecosystems, we used environmental metabarcoding of ITS2 region. We assessed four ecosystems, with different vegetation and levels of impact, ranging from none to high impact (Atlantic forest, Iron outcrops, Eucalyptus, and Grass). Sequence data were compared with culture data obtained from previous studies. The fungal communities (total fungi and yeast) were more similar between Eucalyptus and Atlantic Forest, while Grass and Iron outcrops ecosystems showed greater dissimilarity. Despite its modified state, Grass ecosystem presented the highest alpha diversity values. Yeasts represented a proportion of fungal communities ranging from 1.7 to 17 % of fungal sequences in soil. The Ascomycota:Basidiomycota ratio was higher for the total fungi analysis, while a greater proportion of Basidiomycota was observed with the yeast analysis. Grass ecosystem was the only exception, where a higher proportion of ascomycetous yeasts was detected. The yeast communities responded to the environmental stress caused by the mining activity, resulting in changes in the composition, mainly increasing the abundance of black yeasts. Saitozyma podzolica relative abundance obtained with ITS sequencing was coherent with the findings obtained with culture data. Despite greater diversity depth obtained by metabarcoding, sequence and culture data were complementary tools in describing the fungal soil community. This study contributes significantly to the inventory of yeast species in tropical and subtropical soils.

O objetivo deste trabalho foi determinar a dimensão da amostra (número de plantas) para estimar a média de caracteres de centeio, avaliados no período de colheita dos grãos. Foram conduzidos oito ensaios de uniformidade (experimentos em branco). Cinco com a cultivar ‘BRS Progresso’ e três com a cultivar ‘Temprano’. No estágio de maturação dos grãos, foram recolhidas, aleatoriamente, 780 plantas (total dos oito ensaios) e avaliados 17 caracteres em cada planta. Foram calculadas estatísticas descritivas e determinou-se a dimensão da amostra para estimar a média, para as amplitudes do intervalo de confiança de 95% (ACI95%) de 5 (maior precisão), 10, 15, 20, 25 e 30% (menor precisão) da média - por reamostragem com reposição. Há variabilidade da dimensão da amostra entre caracteres, cultivares e épocas de sementeira. A dimensão da amostra para a cultivar ‘BRS Progresso’ é menor que para a cultivar ‘Temprano’. Para a estimação da média, para todos os caracteres e épocas de sementeira, com ACI95% máxima de 15, 20, 25 e 30%, são necessárias 352, 197, 127 e 87 plantas da cultivar ‘BRS Progresso’ e 609, 341, 227 e 154 plantas da cultivar ‘Temprano’, respectivamente.

The objective of this work was to determine the sample size (number of plants) to estimate of the mean rye traits, evaluated in the grain harvest period. Eight uniformity trials (blank experiments) were conducted. Five with the cultivar ‘BRS Progresso’ and three with the cultivar ‘Temprano’. At the stage of grain maturation 780 plants (total of eight trials) were randomly collected and 17 traits were evaluated in each plant. Descriptive statistics were calculated and the sample size to estimate the mean at amplitudes of the confidence interval of 95% (ACI95%) 5 (greater precision), 10, 15, 20, 25, and 30% (lower precision) of the mean - was determined by resampling with replacement. There is variability of sample size between traits, cultivars, and sowing dates. The sample size for the cultivar ‘BRS Progresso’ is lower than for the cultivar ‘Temprano’. For the mean estimate, for all traits and sowing dates, with ACI95% maximum of 15, 20, 25, and 30% of the mean, 352, 197, 127, and 87 plants of ‘BRS Progresso’ cultivar and 609, 341, 227, and 154 plants of the ‘Temprano’ cultivar are required, respectively.

RESUMO As doenças do fígado e das vias biliares são causas comuns de morbidade e mortalidade. Procedimentos invasivos com finalidade diagnóstica e terapêutica são frequentemente recomendados nos casos de doenças hepatobiliares. O reconhecimento das indicações e limitações das técnicas comumente empregadas é crucial para uma adequada seleção dos pacientes, maximizando os resultados positivos e reduzindo o risco de complicações. Em 2018, a Sociedade Brasileira de Hepatologia (SBH), em colaboração com a Sociedade Brasileira de Radiologia Intervencionista e Cirurgia Endovascular (SOBRICE) e a Sociedade Brasileira de Endoscopia Digestiva (SOBED) realizaram um encontro exclusivamente voltado para a discussão dos procedimentos invasivos nas doenças hepatobiliares. Este texto resume as principais recomendações discutidas durante o evento, e tem a intenção de auxiliar clínicos, gastroenterologistas, hepatologistas, radiologistas e endoscopistas no uso adequado dos procedimentos invasivos para manejo de pacientes com doenças hepatobiliares.

ABSTRACT Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Society of Interventional Radiology and Endovascular surgery (SOBRICE) and the Brazilian Society of Digestive Endoscopy (SOBED) sponsored a joint single-topic meeting on invasive procedures in patients with hepatobiliary diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to guide clinicians, gastroenterologists, hepatologists, radiologists, and endoscopists for the proper use of invasive procedures for management of patients with hepatobiliary diseases.
