Abstract Uterine leiomyosarcomas, although rare, are the most frequent histological type of uterine sarcomas, and have a poor prognosis even when diagnosed in early stages. More often they present with abnormal uterine bleeding, pelvic mass and/or pelvic pain, making the differential diagnosis with uterine leiomyomas. Due to its rarity and aggressiveness, there is no consensus regarding the treatment algorithm. We describe the case of a woman who presented a spontaneous rupture of leiomyosarcoma, a rare manifestation with few cases described in the literature.

Resumo Os leiomiossarcomas uterinos, embora raros, são o tipo histológico mais frequente de sarcomas uterinos, associados a um mau prognóstico mesmo quando diagnosticados em estadios iniciais. Mais frequentemente apresentam-se com hemorragia uterino anómala, massa pélvica e/ou dor pélvica, fazendo o diagnóstico diferencial com leiomiomas uterinos. Devido à sua raridade e agressividade, não há consenso quanto ao algoritmo de tratamento. Descrevemos o caso de uma mulher com uma rotura espontânea do leiomiossarcoma, uma manifestação rara com poucos casos descritos na literatura.

Resumo Enquadramento: O Observatório Europeu da Droga e da Toxicodependência refere um crescente número de utentes em tratamento por consumo de opiáceos e cannabis. Em Portugal, foram identificadas 72 mortes induzidas por drogas na faixa etária entre os 15 e os 64 anos. Objetivos: Caracterizar, numa amostra de adultos portugueses, os consumos de cannabis, o grau de risco e os policonsumos. Metodologia: Estudo quantitativo, descritivo, correlacional e transversal, com utilização do Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Resultados: Os resultados revelam frequências de consumo mais elevadas que os estudos epidemiológicos de âmbito nacional para todas as substâncias (com exceção do álcool). O consumo de cannabis é maioritariamente de baixo risco, mas há consumo nocivo e provável dependência. O policonsumo existe, principalmente da cannabis com o álcool e tabaco. Conclusão: O consumo de cannabis aumentou nos últimos anos. Há associação do consumo de cannabis com outras substâncias e há uma relativização dos problemas associados à utilização da cannabis, apesar de a avaliação do grau de risco apontar noutro sentido.

Abstract Background: The European Monitoring Centre for Drugs and Drug Addiction reports an increasing number of patients in treatment for opioid and cannabis use. In Portugal, 72 drug-induced deaths were identified in the 15-64 age group. Objectives: To characterize cannabis use, risk grade, and polydrug use in Portuguese adults. Methodology: Quantitative, descriptive, correlational, and cross-sectional study, using the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Results: The results reveal higher frequencies of consumption than nationwide epidemiological studies for all substances (except alcohol). Cannabis use is mostly low risk, but there is harmful use and probable dependence. Polydrug use exists, mainly of cannabis with alcohol and tobacco. Conclusion: Cannabis use has increased in recent years; there is an association of cannabis use with other substances; problems associated with cannabis use are relativized, despite the risk assessment pointing in another direction.

Resumo O cancro do pâncreas é uma das neoplasias malignas mais letais, com uma taxa de sobrevida 1 ano após o diagnóstico de 24% e 5 anos após o diagnóstico de apenas 9%. Estes dados espelham, contudo, o comportamento do subtipo histológico mais prevalente - o adenocarcinoma ductal. Porém, nem todas as neoplasias malignas do pâncreas são adenocarcinomas e nem todas estão a associadas a um prognóstico tão reservado. A Neoplasia Pseudopapilar Sólida do Pâncreas é o exemplo disso: descrita pela Organização Mundial da Saúde como uma neoplasia maligna de baixo grau, é um tumor raro associado a um excelente prognóstico, com uma taxa de sobrevida aos 5 anos de 97%. Mais que uma neoplasia com um prognostico peculiarmente favorável, é uma neoplasia única em todas as suas componentes: histogénese, epidemiologia, apresentação clínica, características imagiológicas, citológicas e imunohistoquímicas e no tratamento. Estas particularidades devem estar presentes e consolidadas no raciocínio clínico de qualquer médico, para que estas neoplasias sejam devidamente reconhecidas e tratadas. Neste sentido, foi realizado este artigo de revisão que visa sumariar os mais relevantes tópicos relacionados com esta entidade clínica.

Abstract Pancreatic cancer is one of the most lethal malignant neoplasms, with a 1-year survival rate after diagnosis of 24%, and a 5-year survival rate of only 9%. While this illustrates the behavior of its main histologic type - ductal adenocarcinoma, there are other histologic subtypes of pancreatic cancer that can harbor excellent prognosis. Solid pseudopapillary neoplasm, described as a rare low-grade malignant neoplasm by the World Health Organization, is the best example of that, having an overall 5-year survival rate of about 97%. Not only the prognosis, but everything about this entity is unique: its histogenesis, epidemiology, presentation, imaging characteristics, cytology features, immunohistochemical profile, and treatment. This explains the urge to improve our understanding about this entity and thus our ability to accurately recognize and manage it. Having this in mind, this article aims to summarize the most relevant topics regarding this entity.

Abstract Aim: To characterize the goal-scoring patterns and investigate the goal process on match outcome during the Intercontinental Beach Soccer Cup Dubai 2019. Methods: A set of 35 goal-scoring patterns were grouped into nine macro-categories: Match-period, Court-zone, Set-play, Open-play, Touching by players before the goal, Offensive method, Goalkeeper-line, Number of passes before the goal, and Ball trajectory. Match outcome in regular time was considered the matches resulting in a loss (n=16), draw (n=8), or win (n=16). The offensive sequences that resulted in the goal were analyzed in all 20 matches during the competition (n=138 goals). Results: The most goals were scored in Open-play (69%), during the 2nd and 3rd periods (36% for each), near to goal (Zone 4; 50%), preceded by 1-touch (67%) and 0-pass (29%), using positional attack (46%), without goalkeeper-line (68%), and with high-ball trajectory (51%). In addition, won matches presented a higher number of goals in Zone 4, 1-touch, Counterattack, 4v4 goal-successful, Receiving pass, Sand-touch, and High-ball compared to draw and loss matches (p<0.001−0.03; Effect Size [ES]=1.24−2.58, large). Conclusion: In summary, winning teams scored their goals mainly in open-play situations and without a goalkeeper-line, using counterattacks to achieve zones near the opponent's goals, and implementing a direct offensive style. In addition, goals scored were usually preceded by 1-touch, both through high-ball and sand-touch ball trajectory. Coaches and practitioners may consider these goal processes to train prescription and deep understanding of the process to goal in elite Beach soccer.

Abstract The relations that argentine writer Ricardo Piglia maintained with the media and mass culture have been partially documented but have always been visible: from his classes on the Argentine novel and Borges on cultural television, film scripts and his narrative work in which he has created works between the police genre, science fiction and fantasy, passing by its proximity to other forms considered extraliterary, such as graphic novel and comic, has opened new ways of receiving his own work and that of the authors of the literary tradition that he has analyzed in his novels, essays and journal notes. Thus, and despite the enormous complexity of attentive reading of his narrative, his interventions in the mass circuits do not make concessions to a non-specialized public with literary studies but at the same time brings him closer to reading Borges, Leopoldo Marechal, Manuel Puig o Roberto Artl, for example. This paper analyzes Piglia’s relationship with the volume La Argentina en pedazos (1993a), a work that was published in a fragmentary and periodic way in Fierro magazine since 1984, and stops in particular in the cartoon versions of some works centrals of argentine literature, such as Esteban Echeverría’s “El matadero”, Cortázar’s “Las puertas del cielo” and Arlt’s Los lanzallamas. The texts selected and studied by Piglia for La Argentina en pedazos suggest, indirectly, the review that the argentine writer makes of his literary tradition; simultaneously, the encounter between two seemingly antagonistic cultural manifestations is part of an aesthetic and political operation that encourages artistic renewal and denounces the violence of the State produced in Argentina since its foundation as an independent nation.

Resumen Las relaciones que el escritor argentino Ricardo Piglia mantuvo con los medios de comunicación y la cultura de masas han sido parcialmente documentadas pero siempre han sido visibles: desde sus clases sobre la novela argentina y Borges en la televisión cultural, sus guiones de cine y su narrativa, en la que ha creado obras a caballo entre el género policial, la ciencia ficción y el fantástico, pasando por sus experimentos con diversas formas -como la novela gráfica y la historieta que aún siguen siendo consideradas extraliterarias-, ha abierto nuevos caminos de recepción de su obra y la de los autores de la tradición literaria que ha analizado en sus novelas, ensayos y notas de diario. Así, y a pesar de la complejidad que supone la lectura atenta de su narrativa, sus intervenciones en los circuitos masivos no hacen concesiones a un público no especializado con los estudios literarios pero al mismo tiempo lo acerca a la lectura de Borges, Leopoldo Marechal, Manuel Puig o Roberto Artl, por ejemplo. El presente artículo analiza la relación de Piglia con La Argentina en pedazos (1993a), obra publicada de manera fragmentaria en la revista Fierro a partir de 1984, y se detiene, en particular, en las adaptaciones de algunas obras centrales de la literatura argentina: “El matadero” de Esteban Echeverría, “Las puertas del cielo” de Julio Cortázar y Los lanzallamas de Arlt. Los textos estudiados por Piglia para La Argentina en pedazos sugieren, indirectamente, una nueva revisión de la tradición literaria; simultáneamente, el encuentro entre dos manifestaciones culturales aparentemente antagónicas forma parte de una operación estética y política que fomenta la renovación artística y denuncia la violencia de Estado producida en la Argentina desde sus inicios como nación independiente.

ABSTRACT Background: Plant-origin proteins are alternatives to substitute the fishmeal in diets for aquatic organism, but their use might require the supplementation of prebiotics, non-digestible components that are metabolized by the intestine microbiota of the host. Goals: To evaluate the effects of inclusion of fructooligosaccharides (FOS) and mannanoligosaccharides (MOS) to diets with plant protein concentrates for fingerling of rainbow trout (Oncorhynchus mykiss). Methods: A basal diet with soy, rice and corn protein concentrates (234, 241 and 170 g/kg, respectively) was supplemented with FOS (D-FOS) and MOS (D-MOS) with 30 g/kg. The basal diet was the control (D-Control), and a commercial diet (Comm) was also used. Diets were fed to triplicate groups of fingerlings of an initial weight of 1.75 ± 0.03 g (mean ± standard error). After 60 days, the growth performance was determined and samples for contents protein and lipids in muscle and liver were taken, as well, samples of blood for serum contents of protein, glucose, and triglycerides. Results: No significant differences were observed in the growth performance among the treatments. Protein content in muscle did not show significant differences; significantly higher values were observed in the protein liver contents of Comm. Lipid contents in liver did not show significant differences, but significantly higher lipid content was observed in the D-MOS for muscle. Contents of serum protein were significantly lower in the Comm and serum triglycerides were significantly higher in the same diet. Conclusions: Regardless the inclusion of FOS and MOS, the results indicate the possibility to use the diets without affecting the growth and wellness of rainbow trout fingerlings, but more research is necessary regarding the possible effects of lipids on liver and muscle.

RESUMEN Antecedentes: Proteínas de origen vegetal son alternativas para sustituir la harina de pescado en alimentos para organismos acuáticos, sin embargo podrían requerir la suplementación con prebióticos, compuestos no digeribles que son metabolizados por la microbiotia del hospedero. Objetivo: Evaluar los efectos de la inclusión de fructooligosacaridos (FOS) y mananoligosacaridos (MOS) en alimentos con concentrados de proteína vegetal para crías de trucha arcoísis (Oncorhynchus mykiss). Métodos: El alimento basal con concentrados de proteína con soya, arroz y maíz (234, 241 and 170 g/kg, respectivamente) se suplementó con 30 g/kg de FOS (D-FOS) y MOS (D-MOS). El alimento basal se uso como control (D-Control) y se utilizó un alimento comercial (Comm). Se alimentaron a grupos por triplicados de crías con un peso inicial de 1.75 ± 0.03 g (promedio ± error estándar). Después de 60 días, se determinó el crecimiento y se tomaron muestras para analizar los contenidos de proteína y lípidos en músculo e hígado, además de sangre para los contenidos en suero de proteína, glucosa y trigliceridos. Resultados: No se observaron diferencias significativas en el crecimiento entre los tratamientos. El contenido de proteína en músculo no mostró diferencias significativas; valores significativamente mayores se observaron en el contenido de proteína del hígado de Comm. Los contenidos de lípidos en el hígado no mostraron diferencias significativas, pero el contenido de lípidos fue significativamente mayor en el músculo de D-MOS. Los contenidos de proteína en el suero fueron significativamente menores en Comm y los trigliceridos en el fueron significativamente mayores en el mismo alimento. Conclusiones: Independientemente de la inclusión de FOS y MOS, los resultados indicaron la posibilidad de utilizar los alimentos sin afectar el crecimiento y el bienestar de crías de trucha arcoíris, no obstante más investigación es necesaria sobre los posibles efectos en el contenido de lípidos en el hígado y el músculo.

Resumo: O armazenamento pós-colheita de frutos carnosos é uma estratégia usada para melhorar a qualidade das sementes. O objetivo deste estudo foi avaliar o armazenamento pós-colheita de frutos de C. baccatum var. baccatum (pimenta cumari) e relacioná-lo à atividade de enzimas antioxidantes e ao potencial fisiológico das sementes. Frutos de cor vermelha (65 dias após a antese) foram colhidos e armazenados a 20 °C por 0, 5, 10, 15 e 20 dias. As sementes foram removidas e avaliadas quanto ao grau de umidade, qualidade fisiológica, atividade de enzimas antioxidantes e conteúdo de proteínas. As médias foram ajustadas às equações de regressão e depois avaliadas por análise multivariada (PCA). A umidade e o peso de 100 sementes diminuíram com o armazenamento pós-colheita. Os períodos de armazenamento de 5 e 10 dias levaram a um aumento na germinação. A condutividade elétrica foi maior nos períodos de armazenamento de 0 e 20 dias. A matéria seca e o teor de proteína aumentaram aos 5 e 10 dias. As enzimas exibiram reduções de atividade comparando 0 e 20 dias. O armazenamento pós-colheita de frutos de C. baccatum por 5 e 10 dias melhora o potencial fisiológico das sementes e está relacionado à maturidade fisiológica. A maturação incompleta de sementes de cumari obtidas a partir de frutos não armazenados (0 dias), está relacionada a maior atividade enzimática, maior estresse oxidativo e baixa germinação e vigor. O não armazenamento pós-colheita dos frutos e o armazenamento por mais de 10 dias contribui para o menor potencial fisiológico de sementes de pimenta cumari.

Abstract: Post-harvest storage of fleshy fruit is a strategy used for improving seed quality. The aim of this study was to evaluate post-harvest storage of the fruit of C. baccatum var. baccatum (cumari pepper) and relate it to antioxidant enzyme activity and seed physiological potential. Red-colored fruit (65 days after anthesis) was gathered and stored at 20 °C for 0, 5, 10, 15, and 20 days. The seeds were removed and evaluated for moisture content, physiological quality, antioxidant enzyme activity, and protein content. The means were fitted to regression equations and then passed through multivariate analysis (PCA). Seed moisture and 100-seed weight decreased through post-harvest storage. The 5- and 10-days storage periods led to an increase in the germination. Electrical conductivity was greater for the 0- and 20-day storage periods. Dry matter and protein increased in the 5- and 10-days. Enzymes exhibited reductions of activity comparing 0 and 20 days. The post-harvest storage of C. baccatum fruit for 5 and 10 days improves seed physiological potential and is related to physiological maturity. The incomplete maturation of cumari seeds obtained from unstored fruit (0 days) is related to greater enzyme activity, greater oxidative stress, and low germination and vigor. The lack of post-harvest storage of fruit and storage of fruit for longer than 10 days contributes to a lower physiological potential of cumari pepper seeds.

Marco contextual: El ingreso en cuidados intensivos puede causar efectos adversos que conducen a situaciones de incapacidad funcional, que persisten durante mucho tiempo. La rehabilitación temprana puede prevenir o poner límite a estas situaciones. Objetivos: Caracterizar el nivel funcional y las dependencias en el alta de cuidados intensivos y verificar el momento de inicio de las intervenciones de enfermería de rehabilitación. Metodología: Estudio descriptivo/exploratorio, método cuantitativo, en una muestra de 30 pacientes. Resultados: Puntuación media del Medical Research Council de 27 (primera evaluación) y 38 (alta). El valor medio de la Medida de Independencia Funcional en autocuidado, movilidad/transferencia fue 2. La primera intervención de enfermería de rehabilitación ocurrió, de media, en el 10º día, y la primera vez que se levanta después de 13 días. Conclusión: En el momento del alta se observaron niveles altos de dependencia funcional en el autocuidado básico, así como la movilidad/transferencia, por lo que fue necesario mejorar su caracterización para la continuidad de los cuidados de rehabilitación. La movilización de los pacientes en estado crítico debe tener lugar en una fase temprana.

Enquadramento: O internamento em cuidados intensivos pode provocar efeitos adversos que originam situações de incapacidade funcional, que persistem por tempo prolongado. A reabilitação precoce pode impedir ou limitar essas situações. Objetivos: Caracterizar o nível funcional e dependências na alta dos cuidados intensivos e verificar o momento de início das intervenções de enfermagem de reabilitação. Metodologia: Estudo descritivo/exploratório, método quantitativo, numa amostra de 30 doentes. Resultados: Valor médio do Medical Research Council de 27 (primeira avaliação) e de 38 (alta). O valor médio da Medida de Independência Funcional, nos autocuidados, mobilidade/transferências foi de 2. A primeira intervenção de enfermagem de reabilitação ocorreu, em média, ao 10º dia, e o primeiro levante após 13 dias. Conclusão: No momento da alta verificaram-se elevados níveis de dependência funcional no autocuidado básico e mobilidade/transferências, sendo necessário melhorar a sua caraterização para a continuidade de cuidados de reabilitação. A mobilização dos doentes críticos deve acontecer precocemente.

Background: Stays in the intensive care unit can cause adverse effects that lead to situations of functional disability, which persist for a long time. Early rehabilitation can prevent or limit such situations. Objectives: To characterize the functional level and dependencies at discharge from intensive care. To assay the timing for initiating rehabilitation nursing interventions. Methodology: Descriptive/exploratory study, quantitative method, in a sample of 30 patients. Results: Average of Medical Research Council value was 27 (first evaluation) and 38 (at discharge). The mean value of the Functional Independence Measure, in the area of self-care, mobility / transfers was 2. The first intervention of rehabilitation nursing occurred, on average, on the 10th day and the patient got out of bed after 13 days. Conclusion: At discharge, there were high levels of functional dependence at the level of basic self-care and mobility/transfers, and their characterization should be improved for the continuity of rehabilitation care. Early mobilization of critical patients is necessary.

Abstract: Background and Aims: Cedrela odorata (Spanish cedar) is a tropical tree native to America with an important international trade market. In this study, the morphological variation of C. odorata was compared among three conditions: logging, plantations, and natural populations, with the objective to evaluate the current condition of managed populations after harvesting and in plantations, in contrast to relatively well-preserved populations. Methods: Two sites were chosen for each condition. The population density and four morphological attributes were measured: diameter at breast height, height, angle of branch insertion and crown form. A multivariate approach was used to compare the morphological variation among conditions (generalized discriminant factors analysis) and determine total variation distributed among size classes (cluster analysis), as well as assignment of these classes to each condition (canonical correspondence analysis). Key results: Four significantly different size classes were identified among all populations with specific association to condition. Strongest correlations were between highest trees with natural populations and small trees with plantations. Forest management, including harvesting and plantation conditions, reduced the phenotypical variation and modified the dasometrical attributes of C. odorata. The logging of the better shaped phenotypes increased the smaller size trees frequency compared to commercial size individuals, and changed the forest composition favoring small categories. Conclusions: The forest exploitation generates homogenization in median height-class and the plantation in lower height-class. In both cases, the harvestable trees are scarce, even after 20 years of management; and they are non-existent in plantations of 15 years. These results suggest that the removal of the highest trees, as well as forest plantations, are not being effective to wood production since they do not reach commercial sizes in the time of recovery or projected growth.

Resumen: Antecedentes y Objetivos: Cedrela odorata (cedro) es un árbol tropical nativo de América con un importante mercado internacional. En el presente estudio, se comparó la variación morfológica de C. odorata en tres condiciones: bajo extracción, plantaciones y poblaciones naturales, con el objetivo de evaluar la condición actual de las poblaciones después de la extracción y en plantaciones, en contraste con las poblaciones relativamente bien conservadas. Métodos: Se eligieron dos sitios para cada condición. Se midió la densidad poblacional y cuatro atributos morfológicos: diámetro a la altura del pecho, altura, ángulo de inserción de las ramas y forma de la copa. Se usó una aproximación multivariada para comparar la variación morfológica entre condiciones (análisis de funciones discriminantes generalizado), y para determinar la variación total distribuida entre clases de talla (análisis de agrupamiento); además, se asignaron esas clases a cada condición (análisis de correspondencias canónicas). Resultados clave: En todas las poblaciones fueron identificadas cuatro clases de talla significativamente distintas. Las correlaciones más fuertes fueron entre los árboles más grandes con las poblaciones naturales y los más pequeños con las plantaciones. El manejo forestal, que incluye las condiciones bajo extracción y las plantaciones, redujo la variación fenotípica y modificó los atributos dasométricos de C. odorata. La extracción de fenotipos mejor conformados incrementa la frecuencia de árboles de menor talla, respecto a individuos de tamaño comercial, y cambia la composición del bosque favoreciendo las categorías pequeñas. Conclusiones: El aprovechamiento forestal genera homogenización en clases de talla mediana, en cambio, en las plantaciones se homogenizan las clases de menor tamaño. En ambos casos, los árboles cosechables son escasos, aún después de 20 años de manejo, y no existen en cultivos de 15 años. Estos resultados sugieren que la remoción de los árboles más grandes, así como las plantaciones forestales, no son efectivas para la producción de madera puesto que no se encontraron árboles de tallas comerciales en el tiempo de recuperación o crecimiento proyectado.

Abstract: En | Text: En | PDF: En

Superduplex stainless steels (SDSS) are frequently employed in the petrochemical industries where is required high mechanical strength, toughness, and corrosion resistance. However, these properties can be affected by deleterious phases formation due thermomechanical processes applied in the field during pipes and vessels construction. This work propose the nondestructive microstructural characterization of deleterious phases precipitated in SDSS isothermally treated in 800 and 850ºC using portable double loop electrochemical polarization reactivation tests (DL-EPR). The results obtained in this nondestructive test are quite close to those obtained by conventional test, and can be correlated with the amount of deleterious phases precipitated. It can be concluded that the microstructural degradation of superduplex stainless steel can be evaluated by portable DL-EPR test with slow sweep rates, using a special cell and a proper electrolyte at room temperature.

A casa da Comenda, situada numa das mais belas paisagens da Arrábida, sobranceira ao rio Sado, é um dos mais sublimes, mas menos conhecidos projetos do arquiteto Raul Lino. Aqui, de forma inigualável, o seu génio criador e sua profunda compreensão pela Natureza resultam numa simbiose quase perfeita entre paisagem e construção. Tão bem retratada por Artur Pastor, esta casa encerra uma história que começou vários séculos antes, e que lhe atribui, enquanto lugar de permanência humana, um significado mais vasto. Se, no dealbar do século XX, este é o lugar de implantação de uma estância de veraneio aristocrática, quinze séculos antes, em pleno domínio romano, servia de cenário a um complexo industrial. Pelo meio, foi palco de importantes episódios na história da nação, dos quais se destaca uma enigmática “reunião” convocada de urgência por D. Manuel I, como comprova um documento pouco estudado que encontramos no Arquivo Municipal de Lisboa.

The House of Comenda, located in the astonishing landscape of Arrábida, overlooking the Sado river, is one of the most sublime, but lesser-known projects of the architect Raul Lino. Here, in a unique way, his creative genius and his deep understanding about nature result in an almost perfect symbiosis between landscape and construction. Beautifully depicted by Artur Pastor, this house contains a history that began centuries earlier, which assigns it, while human establishment, a wider significance. If, at the beginning of the 20th century, this is the vacation house of an aristocratic family, fifteen centuries earlier, during the Roman Empire, it constituted a fish processing industrial complex. Meanwhile, this place witnessed remarkable episodes in Portugal's history, as, for example, an enigmatic “meeting” urgently convened by King Manuel I, described by a little known document we found in the Municipal Archives of Lisbon.
