ABSTRACT Objective: This study aimed to analyze the prognosis of women with breast cancer by molecular subtypes, sociodemographic variables, and clinical and treatment characteristics. Methods: This hospital-based retrospective cohort study analyzed 1,654 women over 18 years of age diagnosed with invasive breast cancer from 2000 to 2018. Data were extracted from Brazil’s Oncocenter Foundation of São Paulo. The variables analyzed were age, histology, molecular subtypes, clinical staging, treatment type, and diagnosis-to-treatment time. Cox regression analysis was applied to estimate death risk. Results: Women with HER-2-positive (nonluminal) and triple-negative molecular subtypes were more than twice more likely to be at risk of death, with adjusted hazard ratio — HRadj=2.30 (95% confidence interval — 95%CI 1.34–3.94) and HRadj=2.51 (95%CI 1.61–3.92), respectively. A delayed treatment associated with an advanced clinical stage at diagnosis increased fourfold the risk of death (HRadj=4.20 (95%CI 2.36–7.49). Conclusion: In summary, besides that interaction between advanced clinical stage and longer time between diagnosis and treatment, HER-2-positive (nonluminal) and triple-negative phenotypes were associated with a worse prognosis. Therefore, actions to reduce barriers in diagnosis and treatment can provide better outcome, even in aggressive phenotypes.

RESUMO Objetivo: O objetivo deste estudo foi analisar o prognóstico de mulheres com câncer de mama de acordo com os subtipos moleculares, variáveis sociodemográficas, características clínicas e de tratamento. Métodos: Este foi um estudo de coorte retrospectivo de base hospitalar. Foram analisadas 1.654 mulheres maiores de 18 anos diagnosticadas com câncer de mama invasivo entre 2000 a 2018. Os dados foram extraídos da Fundação Oncocentro de São Paulo, Brasil. As variáveis analisadas foram idade, histologia, subtipo moleculares, estadiamento clínico, tipo de tratamento e tempo entre o diagnóstico e tratamento. A análise de regressão de Cox foi aplicada para estimar o risco de morte. Resultados: As mulheres que apresentaram os subtipos moleculares HER-2-positivo (não luminal) e triplo negativo tiveram risco de morte quase duas vezes maior respectivamente, com razão de risco ajustada — HRaj=2,30 (intervalo de confiança de 95% — 95%IC 1,34–3,94) e HRaj=2,51 (95%IC 1,61–3,92). O atraso no tratamento associado ao avanço do estadiamento clínico ao diagnóstico aumentou em quatro vezes o risco de morte (HRaj=4,20 (IC95% 2,36–7,49). Conclusão: Os fenótipos HER-2-positivo (não luminal) e triplo negativo, além da interação entre estágio clínico avançado e maior tempo entre o diagnóstico e o tratamento, associaram-se a pior prognóstico. Assim, ações para reduzir as barreiras no diagnóstico e tratamento podem proporcionar melhores resultados, mesmo em fenótipos agressivos.

ABSTRACT: Several toxic diseases cause mortality in cattle in southern Rio Grande do Sul State, Brazil. The aim of this study was to carry out a comparative analysis to determine the evolution of the main intoxications that occurred in cattle in southern Rio Grande do Sul from 1979 to 1999 and from 2000 to 2020. The spatial distribution and trend of occurrence of these intoxications over the 42 years in southern Rio Grande do Sul were determined using data from the Regional Diagnostic Laboratory of the Faculty of Veterinary Medicine at the Federal University of Pelotas (LRD-UFPel), which will make it possible to predict their occurrence in the coming years. From January 1979 to December 1999, 3,753 bovine materials were received for diagnosis at LRD-UFPel, and 3,653 cases were received from 2000 to 2020. Of the total number of materials received, 394 were diagnosed as intoxications, with 140 cases from 1979 to 1999 and 252 cases from 2000 to 2020. Out of 140 cases diagnosed in the first 21 years of operation of the LRD-UFPel, 113 (80.7%) were poisoning by plants, 22 (15.7%) by fungi outbreaks, and five (3.57%) by chemical substances. From 2000 to 2020, of the 252 diagnosed outbreaks 224 (88.8%) were caused by toxic plants, 10 (3.96%) by fungi, 12 (4.76%) by chemical substances, and six (2.38%) by insects. In the temporal trend analysis, a significant linear trend was observed with values of p=0.03 and an annual percentage change (APC) of 2.5 for the increase in the number of diagnoses of poisoning in general over the 42 years of the study. When analyzing the temporal trend of poisoning by Senecio spp., there was an increase in the occurrence of the diagnosis, with different characteristics and inflection points over time, with an annual growth rate of 9% in diagnoses during the first 21 years. There was a decrease in the occurrence of poisoning by Solanum fastigiatum, Echium plantagineum, and Claviceps paspali. Furthermore, poisoning by Ramaria flavo-brunnescens and Baccharis coridifolia maintained a similar percentage throughout the study period. It is concluded that toxic diseases will likely remain important causes of cattle death in the region.

RESUMO: Na região sul do Rio Grande do Sul, dentre as principais enfermidades que causam mortalidade em bovinos estão diversas doenças tóxicas, destacando-se as intoxicações por plantas e micotoxicoses. O objetivo deste trabalho foi realizar um estudo comparativo para determinar a evolução das principais intoxicações que ocorreram em bovinos na região sul do Rio Grande do Sul de 1979 a 1999 e de 2000 a 2020, estabelecendo a distribuição espacial e a tendência de ocorrência dessas intoxicações nos 42 anos de atividades do Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas (LRD-UFPel), possibilitando prever sua ocorrência nas próximas décadas. Foram recebidos no laboratório de janeiro de 1979 a dezembro de 1999 e de janeiro de 2000 a dezembro de 2020, 3.753 e 3.653 materiais de bovinos para diagnóstico, respectivamente. Do total de materiais recebidos, 392 foram diagnosticados como intoxicações, sendo 140 entre os anos de 1979 a 1999 e 252 casos de 2000 a 2020. Dos 140 casos diagnosticados nos primeiros 21 anos de funcionamento do LRD-UFPel, 113 (80,7%) foram intoxicações por plantas, 22 (15,7%) intoxicações por fungos e cinco (3.6%) intoxicações por substâncias químicas. Entre os anos de 2000 e 2020 dos 252 casos diagnosticados 224 (88,8%) foram por plantas tóxicas, 10 (3,9%) por fungos, 12 (4,8%) por substâncias químicas e seis (2,4%) foram por insetos. Na análise de tendência temporal foi observada uma tendência linear significativa com valores de p=0,003 e mudança percentual anual (APC) de 2,5 no crescimento do número de diagnósticos de intoxicações em geral ao longo de todo o período de funcionamento do LRD-UFPel. Quando analisada a tendência temporal da intoxicação por Senecio spp. houve aumento na ocorrência do diagnóstico, com características e pontos de inflexão diferentes ao longo do tempo, sendo observado crescimento anual de 9% nos diagnósticos durante os primeiros 21 anos. Conclui-se que houve queda na ocorrência das intoxicações por Solanum fastigiatum, Echium plantagineum e Claviceps paspali e que as intoxicações por Ramaria flavo-brunnescens e Baccharis coridifolia mantiveram um percentual semelhante em todo o período. Além disso, as doenças tóxicas provavelmente permanecerão como importantes causas de morte de bovinos na região apesar de bem conhecidas, devido em parte, às dificuldades em fazer o controle das mesmas.

RESUMO Amostras de plasma rico em plaquetas de 50 cavalos saudáveis, de cinco raças diferentes (Puro Sangue de Corrida, Crioula, Brasileiro de Hipismo, Pônei Brasileiro e sem raça definida), foram investigadas quanto à concentração plaquetária em relação à raça, à idade e ao sexo. Além disso, um escore foi estabelecido para correlacionar o aspecto físico do PRP com a contagem plaquetária. A contagem celular foi realizada por um analisador hematológico automático e pelo método manual. A análise física baseou-se na cor, no aspecto e na capacidade de separar hemocomponentes. Pôneis tiveram concentração plaquetária significativamente maior que os Brasileiros de Hipismo (P<0,05), mas as demais comparações entre raças não apresentaram diferença quanto à contagem plaquetária. Não houve diferença para o gênero, mas a idade demonstrou correlação fraca com as concentrações plaquetárias do PRP (rs = -0,24). A maioria dos PRPs apresentaram coloração amarela, e a separação dos hemocomponentes não mostrou correlação com a contagem plaquetária, mas o aspecto apresentou uma correlação moderada (rs = 0,30). Os resultados deste estudo sugerem que a concentração plaquetária do PRP pode ser influenciada por fatores intrínsecos, como a raça. Além disso, a análise do aspecto do PRP pode ajudar na avaliação da qualidade do produto quando não há acesso à contagem plaquetária.

ABSTRACT Platelet rich plasma samples from 50 healthy horses of five different breeds (Thoroughbreds - TB, Brazilian Criollo Horses - BCH, Brazilian Sport Horses - BSH, Miniature Horses - MH and Crossbred Horses - CB), were investigated as to breed, age, and gender effect for platelet concentration. Moreover, a score for physical analysis was established to correlate PRP physical aspect with platelet count. Platelet count was performed by an automatic hematology analyzer and by manual count. PRP physical analysis was based on color, aspect, and capacity to separate blood components. MH showed significant higher platelet concentration than BSH (p<0.05), while the other breed comparisons showed no significant difference. There was no significant difference for gender but there was a weak correlation of age with PRP platelet concentrations (rs = -0.24). Most of the PRP presented yellow color, the separation of blood components showed no correlation, but the aspect showed a moderate correlation (rs = 0.30) with platelet count. Results suggest that PRP platelet concentration can be influenced by intrinsic factors such as breed. Additionally, the analysis of PRP aspect can help to evaluate the quality of the product when there is no access to platelet counts.

Abstract: This article aims to consolidate the regulatory sandbox as a source of normative production to address the legal regulation of the development and application of nanotechnology. The paradox that exists between nanotechnology and risk, both inherent to development, is presented as a problem for society as it must deal with limits. For this, a legal regulation is expected. But, what legal regulation is being considered? Certainly, that produced by social intervention as a factor for validating and managing the limits of this paradox. In this sense, following another Brazilian initiative, The regulatory sandbox is presented as a possibility of legal regulation of the development and application of nanotechnology. To achieve this objective, it uses the project of the Brazilian securities commission that, together with the Inter-American Development Bank, implemented the so called sandbox normative process in order to legally regulate technology-based financial companies at an early stage. In addition, meeting the needs of risk control and favoring the development of society. The methodology used is hypothetical-inductive which qualitative approach and with a systemic-constructivist approach. As a research technique, it uses data collection, document and literature review. The results suggest that in the case of nanotechnology development and given the impossibility for the constituent legislator to know such an object, the regulatory sandbox can enable a dynamic regulation and democratic norms where all actors participate in the construction of the regulatory process, therefore impacting decision-making about innovation.

Resumen: Consolidar el sandbox regulatorio como fuente de producción normativa para abordar la regulación legal del desarrollo y aplicación de la nanotecnología es el objetivo de este artículo. Dada la paradoja existente entre la nanotecnología y el riesgo, ambos inherentes al desarrollo, la cual se presenta como un problema para la sociedad al tener que lidiar con límites, sería deseable conseguir una regulación legal. Pero, ¿qué regulación legal se está considerando? Ciertamente, a la producida por la intervención social como factor de validación y gestión de los límites de esta paradoja. En este sentido, y retomando otra iniciativa brasileña, el sandbox regulatorio se muestra como una posibilidad de regulación legal del desarrollo y aplicación de la nanotecnología. Para lograr este objetivo, nos basaremos en el proyecto de la Comisión de Valores de Brasil, la cual, junto con el Banco Interamericano de Desarrollo, implementó el proceso normativo denominado sandbox, para regular legalmente las empresas financieras de base tecnológica en una etapa temprana, además de atender las necesidades de control de riesgos y favorecer el desarrollo de la sociedad. La metodología utilizada es hipotético-inductiva, de naturaleza cualitativa y de enfoque sistémico-constructivista. Como técnica de investigación, se utiliza la recolección de datos, documentos, y el análisis de literatura. Los resultados indican que en el caso del desarrollo nanotecnológico y ante la imposibilidad de que el legislador constituyente conozca tal objeto, el sandbox regulatorio puede dar paso a normas dinámicas y democráticas donde todos los actores participan en la construcción del proceso regulatorio, impactando, por tanto, la toma de decisiones sobre la innovación.

This paper concentrates on whether systematic variations in pitch, intensity, and duration can be observed as a function of the focused or discourse-given status of a constituent in Kinyarwanda (Guthrie code JD.61), and a relatively recent variety of "New English" in contact with this Bantu language. Kinyarwanda is a tone language, in which the information-structural notion of focus has been reported to be expressed through changes in word order, with focus appearing clause-finally (Kimenyi 1988, Ndayiragije 1999, Ngoboka 2016). In contrast, Standard English is well-known for the prosodic boost associated with narrowly focused words and the prosodic reduction of post-focal items. Crosslinguistically, the prosodic expression of focus and givenness is progressively being considered a marked feature. Zerbian (2015a) predicts that it should not be found in a second language or a contact variety if it is not already present in the first language of a speaker or a group of speakers. Our study finds no evidence that information focus, exhaustive focus, or givenness systematically affect the prosody of Kinyarwanda. We also find no systematic effect of information structure in the variety of English spoken by our Rwandan participants, confirming that this is probably an area of English that is difficult to acquire.

RESUMO: As condenações no abatedouro de frangos podem representar uma visão geral da saúde das granjas e da eficácia dos programas de bem-estar, bem como revelar diferenças fenotípicas entre linhagens. O objetivo deste estudo foi investigar a prevalência de condenação entre quatro híbridos comerciais de frangos de corte e a oscilação de condenações em diferentes épocas em um frigorífico de aves. Os dados das condenações do Serviço Federal de Inspeção de um abatedouro foram analisados durante um ano, no qual foram observadas 12,81% de condenações parciais e 0,41% de condenações totais. Houve diferença na condenação total e parcial entre os híbridos avaliados, sendo o híbrido Hubbard o com maior número de condenações (0,67% - 17,71%), seguido por Ross 95 (0,42% - 14,21%), Cobb (0,30%). - 10,03%); e Cobb Fast (0,26% - 9,29%). A análise entre as estações do ano demonstrou uma maior taxa de condenação no inverno e menor taxa no outono para condenação total e parcial. Hubbard apresentou as maiores taxas e Cobb Fast as mais baixas para a maioria das causas de condenações. Concluímos que a causa metabólica resultou em mais perdas por condenação total, enquanto a contaminação ou tecnopatias representaram as maiores taxas em perdas parciais. A linhagem de frango de corte e a época do ano podem influenciar nas causas de condenação no abatedouro. Essas informações devem ser consideradas pela indústria e pelas granjas no planejamento sanitário, considerando o impacto financeiro devido às perdas por condenações de carcaças.

ABSTRACT: Condemnations in the broilers abattoirs can represent an overview farms health and effectiveness of welfare programs, as well as predisposition between hybrids. The aim of this study was to investigate the prevalence of condemnation among four commercial broiler hybrids and the oscillation of condemnations in different seasons in a poultry abattoir. Data from condemnations of the Federal Inspection Service of a slaughterhouse were analyzed during one year, in which a total of 12.81% of partial condemnations were observed and total condemnations represented 0.41% of slaughtered broiler. There was a difference in total and partial condemnation among the hybrids evaluated, with Hubbard hybrid being the one with the highest number of condemnations (0.67% - 17.71%), followed by Ross 95 (0.42% - 14.21%), Cobb (0.30% - 10.03%); and Cobb Fast (0.26% - 9.29%). The analysis between the seasons showed a higher conviction rate in winter and a lower rate in autumn for both total and partial condemnation. Hubbard had the highest rates and Cobb Fast the lowest for most causes of condemnation. We concluded that the metabolic cause led to higher losses by total condemnation, while contamination or technopathies represented the highest rates in partial losses. The broiler hybrid and the time of year may influence the causes of condemnation in the abattoir. This information should be considered by the abattoir and the farms in sanitary planning, considering the financial impact due to losses by condemnations of carcasses.

The success of different categories of legal professionals in building positions of state power in Brazil since the end of the military regime is in line with the legitimation of models of law and international cooperation. This article focuses on the connections between Brazilian legal actors and the international ‘fight against corruption’. By looking at the international connections of Brazil’s Public Prosecutor’s Office (MPF), we aim to show how the promotion of anti-corruption models of law is the result of corporate cooperation strategies. We cite as evidence overseas travel by MPF agents and their connections with the international field in recent decades. We start by analyzing cooperation documents and then attempt to trace the MPF’s pathway towards internationalization during the 2000s.

Abstract Vasconcellea quercifolia A.St-Hil. (Caricaceae) is a non-conventional food plant (PANC) of Brazil. The aim of this study was to investigate the physical, chemical, and nutritional properties of green and ripe fruits and medullary parenchyma of V. quercifolia A.St-Hil., in order to develop functional foods. We determined humidity, pH, ash content, protein content, carbohydrate content, fibre content, carotenoid content, ascorbic acid content, and aminograms of green and ripe fruits and of medullary parenchyma from three specimens, following existing methodologies. Green fruits had higher protein and fibre contents, and ripe fruits had higher ash, carbohydrate, and carotenoid contents, higher than other most consumed fruits. On the other hand, medullary parenchyma had higher ash content and humidity. Glutamic acid, aspartic acid, and lysine were the amino acids with the highest contents, mainly in green fruits. Aside from medullary parenchyma, used as food in the past, both green and ripe fruits can be used for the development of new food products with functional properties and potential for new alternatives for consumption.

AIMS: To describe the epidemiology and injury severity of patients with extremity gunshot injuries in an area with a high rate of interpersonal violence PATIENTS AND METHODS: This is a prospective cohort study of patients who presented with an extremity gunshot injury and were recorded as part of a trauma registry at a large tertiary care hospital in Cape Town, South Africa, between June 2015 and April 2016. Patient demographics, injury severity scores, injury patterns and referral pathways were evaluated. RESULTS: Of 1 123 gunshot trauma admissions in ten months, 290 (25.8%) patients (91.5% males, n=269) with a median age of 26 years (IQR 13.0) presented with extremity injuries. Median injury severity score (ISS) was 4.0 (IQR 8.0). Only one-fifth of patients had an ISS of 15 or more (n=50, 17%). Upper extremity injuries were associated with a higher risk of fractures (Rr 2.15, p=0.05), higher number of nerve injuries (p=0.01), and a two times higher mean ISS (p=0.01). Admissions between 7pm and 7am with limited staffing at the emergency department were twice as high as the day admissions (n=169, 57.5% versus n=79, 26.9% CONCLUSION: There is a high trauma load on the emergency department and orthopaedic service due to extremity gunshot injuries. Although upper extremity gunshot wounds constituted a red flag for higher injury severity, the overall injury severity was low. Inadequate timing and selection of emergency referrals of patients with low ISS are avoidable aggravators of this burden and should be targeted to increase efficiencies in the care of these patients Level of evidence: Level 4

RESUMO O objetivo deste artigo é mostrar que as interpretações "tradicional" e "resoluta" não livraram o "Tractatus" da aparente autoderrota paradoxal. Argumento que essas leituras apresentam apenas uma nova roupagem ao paradoxo. A leitura "tradicional" de Hacker acaba atribuindo uma conspiração metafísica ao "Tractatus", o que é incompatível com os objetivos do livro. A leitura "resoluta" de Diamond e Conant atribui a Wittgenstein uma conspiração autoral, o que contradiz suas opiniões sobre autoria e método. Com base nas dificuldades encontradas em ambos os lados do debate atual, concluo este artigo propondo vários requisitos que a correta interpretação do "Tractatus" deve preencher.

ABSTRACT The aim of this paper is to show that "traditional" and "resolute" interpretations have not freed the "Tractatus" from the apparent paradoxical self-defeat. I argue that these readings only give it new clothing. Hacker's "traditional" reading ends up ascribing a metaphysical conspiracy to the "Tractatus", which is incompatible with the aims of the book. The "resolute" reading of Diamond and Conant ascribes an authorial conspiracy to Wittgenstein, which contradicts his views on authorship and method. Grounded in the difficulties found in both sides of the current debate, I conclude this paper by proposing several requirements that the correct interpretation of the "Tractatus" should fulfill.

RESUMO O objetivo do presente trabalho foi determinar a presença de anticorpos para Leishmania infantum, Neospora caninum e Toxoplasma gondii, por meio da reação de imunofluorescência indireta (RIFI), em cães (n=78) provenientes da região central do Rio Grande do Sul, necropsiados no Hospital Veterinário da Universidade Federal de Santa Maria (UFSM), bem como avaliar os dados epidemiológicos, sazonais e anátomo-histopatológicos. Do total de animais avaliados, 67,9% (53/78) apresentaram soropositividade para ao menos um agente. A ocorrência de anticorpos para L. infantum, N. caninum e T. gondii foi de 33,3 (26/78), 37,1 (29/78) e 43,5% (34/78), respectivamente. Detectaram-se monoinfecções em 9,4% (5/53) para L. infantum, 18,8% (10/53) para N. caninum e 20,7% (11/53) para T. gondii. As coinfecções foram observadas em 27/53 (50,9%) dos animais. As infecções ocorreram independentemente de idade, sexo, procedência ou raça (P>0,05). Não se verificaram lesões anatomo-histopatológicas relacionadas aos agentes pesquisados, caracterizando-os como animais assintomáticos. Os resultados confirmaram a exposição de cães a esses protozoários na região central do RS e, em especial, demonstraram a circulação do agente causador da leishmaniose em uma área considerada indene para a enfermidade.

ABSTRACT The present paper is aimed to determine the presence of antibodies for Leishmania infantum, Neospora caninum and Toxoplasma gondii by indirect immunofluorescence (IIF) in dogs (n=78) from the central region in the state of Rio Grande do Sul necropsied in the Veterinary Hospital from Universidade Federal de Santa Maria (UFSM). The data was evaluated regarding epidemiological, anatomic, and histopathologic findings. Of the total animals evaluated, 67.9% (53/78) showed seropositivity for at least one agent. The occurrence of antibodies to L. infantum, N. caninum and T. gondii was 33.3% (26/78) 37.1% (29/78) and 43.5% (34/78), respectively. The mono infections were detected in 9.4% (5/53) of L. infantum, 18.8% (10/53) for N. caninum and 20.7% (11/53) T. gondii. The coinfections occurred in 50.9% (27/53) of animals. There were not anatomical and histopathological lesions regarding these surveyed agents, characterizing them as subclinical animals. The results confirmed the exposition of dogs to these protozoa in the central region of the RS, highlighting the circulation of the causer agent of leishmaniasis in an area considered harmless for the disease.
