ABSTRACT The functioning of ecosystems or agroecosystems is mainly dependent on the soil-litterfall interaction. Thus, the objective of this work was to evaluate the effect of different soil use and management systems on the dynamics of decomposition of plant residues of Azadirachta indica (neem) and Gliricidia sepium (gliricidia). The study was conducted in four land occupation systems, namely: remaining forest, agroforestry, agricultural mandala, and pasture. The decomposition rate was estimated using nylon bags (litter bags), containing 20 g of leaves of A. indica and G. sepium, which were arranged on the soil surface of each area for 18, 36, 54, 72, 90, and 108 days. A completely randomized design was used for each species, considering each area as one treatment, with four replications for each collection. The data were subjected to regression analysis and the means were compared by the Tukey's test (p<0.05). More than 85% and 90% of A. indica and G. sepium plant matters, respectively, had been decomposed after 108 days, regardless of the system evaluated, denoting that these species present high decomposition rates. The phytomass half-life time varied from 16 to 23 days for G. sepium and from 25 to 37 days for A. indica, depending on the land use system. Edaphic temperature, soil water content, and leaf physical and chemical characteristics are weight loss predictors. The results provide important information to enable forest management practices.

RESUMO O funcionamento dos ecossistemas ou agroecossistemas depende, sobretudo, da interação solo-serapilheira. Assim, objetivouse avaliar a influência de diferentes sistemas de uso e manejo do solo sobre a dinâmica de decomposição dos resíduos vegetais de Azadirachta indica e Gliricidia sepium. O estudo foi conduzido em quatro sistemas de ocupação da terra, sendo eles: remanescente florestal, sistema agroflorestal (SAF), mandala agrícola e pastagem. A taxa de decomposição foi estimada com o uso de sacolas de nylon (litter bags), contendo 20 g de folhas de A. indica e G. sepium, que foram dispostas na superfície do solo de cada área por um período de 18, 36, 54, 72, 90 e 108 dias. Adotou-se um DIC, considerando cada área como um tratamento e quatro repetições a cada coleta, para ambas as espécies. Os dados foram submetidos a uma análise de regressão e as médias foram comparadas pelo teste Tukey (p<0,05). Após 108 dias, mais de 85 e 90% da fitomassa de A. indica e G. sepium, respectivamente, havia sido decomposta, independente do sistema avaliado, indicando que estas espécies apresentam rápida taxa de decomposição. O tempo de meia-vida (T½) do material vegetal variou de 16 a 23 dias no caso da G. sepium e de 25 a 37 dias no caso da A. indica, dependendo do sistema de uso da terra. A temperatura edáfica, o conteúdo de água do solo e as características físico-químicas da fração foliar são preditores da perda de massa. Esses conhecimentos podem fornecer importantes informações que viabilizem práticas de manejo florestal.

ABSTRACT Understanding the ecological impacts of roads on mammals requires periodic monitoring of roads, and identification of both temporal and spatial distribution of roadkills (i.e., roadkill hotspots). The main aim of the study was to identify the most roadkilled mammals and evaluate the temporal and spatial distribution of roadkills in the RJ-122, a highway that crosses the threaten lowland Atlantic Forest in the state of Rio de Janeiro, southeast Brazil. Between October 2017 and January 2020, an intense monitoring study was conducted, with the carcasses of the roadkilled mammals being collected three times a week. Overall, we recorded 295 roadkilled mammals belonging to 22 species, resulting in 11 roadkills per month for the RJ-122 highway. The black-eared opossum, Didelphis aurita (N=149, 51%) stood out as the most roadkilled mammal, followed by porcupine, Coendou spinosus (N= 24, 8%), crab-eating fox, Cerdocyon thous (N= 23, 8), nine-banded armadillo, Dasypus novemcinctus (N= 23, 8%), and white-tufted marmoset, Callithrix jacchus (N= 20, 7%). Roadkills on the RJ-122 varied throughout the year, being more frequent in the rainy season (N=180) than in the dry season (N=115), and were concentrated in two hotspots, indicating some critical points with high roadkill frequency. Hotspots were associated with areas with dense natural vegetation, which can function as forest corridors in this fragmented landscape. Based on our results, several mitigation measures are recommended for the RJ-122 highway.

RESUMO Compreender os impactos ecológicos das estradas sobre a fauna de mamíferos requer o monitoramento periódico das estradas e a identificação da distribuição temporal e espacial dos atropelamentos (ou seja, hotspots de atropelamentos). O objetivo principal do estudo foi identificar os mamíferos mais atropelados e avaliar a distribuição temporal e espacial dos atropelamentos na RJ-122, uma rodovia que atravessa a ameaçada Mata Atlântica de baixada no estado do Rio de Janeiro, sudeste do Brasil. Entre outubro de 2017 e janeiro de 2020, foi realizado um intenso estudo de monitoramento, com a coleta três vezes por semana das carcaças dos mamíferos atropelados. Ao todo, registramos 295 mamíferos atropelados pertencentes a 22 espécies, resultando em 11 atropelamentos por mês para a rodovia RJ-122. O gambá-de-orelha-preta, Didelphis aurita (N=149, 51%) destacou-se como o mamífero mais atropelado, seguido pelo ouriço-cacheiro, Coendou spinosus (N= 24, 8%), cachorro-do-mato, Cerdocyon thous (N= 23, 8%), tatu-galinha, Dasypus novemcinctus (N= 23, 8%) e sagui-de-tufo-branco, Callithrix jacchus (N= 20, 7%). Os atropelamentos na RJ-122 variaram ao longo do ano, sendo mais frequentes na estação chuvosa (N=180) do que na estação seca (N=115), e se concentraram em duas áreas, indicando alguns pontos críticos com alta frequência de atropelamentos. Os hotspots foram associados a áreas com vegetação natural densa, que podem funcionar como corredores florestais nesta paisagem fragmentada. Com base em nossos resultados, várias medidas de mitigação são recomendadas para a rodovia RJ-122.

Abstract The construction of highways is responsible for access to previously protected areas, resulting in changes in landscape and dynamics of the animal populations that live in these areas. These enterprises are the major responsible for the mortality of wild animals, surpassing hunting and even the trafficking of animals. The objective of this study was to make a list that reflects the diversity of amphibians and reptile’s road-killed along the BR-040, a highway that crosses the threaten lowland Atlantic Forest in Southeastern region of Brazil, including the use of microhabitats, lifestyle, activity pattern, reproductive cycles, and possible rare or endangered species. The study area consists of 180,4 km of highways. Monitoring began in 2006 and continues to the present day. A total of 1,410 individuals from 60 species were recorded in this study. The reptiles were more frequent in number of individuals and species. The commonest species recorded were Crotalus durissus and Dipsas mikanii. We have registered a single endangered species: Ranacephala hogei. The highest rates of road-kill were recorded during the wet season. Road-kills of fauna is a major threat to species, studies are of great importance to define plans that seek to mitigate the effects generated by these enterprises.

Resumo A construção de rodovias é responsável pelo acesso a áreas anteriormente protegidas, resultando em alterações na paisagem e na dinâmica das populações animais que vivem nessas áreas. Esses empreendimentos são os maiores responsáveis pela mortalidade de animais silvestres, superando a caça e até mesmo o tráfico de animais. O objetivo deste estudo foi realizar uma lista que reflita a diversidade de anfíbios e répteis atropelados ao longo da BR-040, uma rodovia que atravessa a ameaçada Mata Atlântica na região Sudeste do Brasil, incluindo o uso de microhabitats, estilo de vida, padrão de atividade, ciclos reprodutivos, e possíveis espécies raras ou ameaçadas. A área de estudo é constituída por 180,4 km de rodovias. O monitoramento começou em 2006 e segue até os dias atuais. Ao todo 1.410 indivíduos de 60 espécies foram registrados nesse estudo. Os répteis foram mais frequentes, em número de indivíduos e espécies. As espécies mais comumente registradas foram Crotalus durissus e Dipsas mikanii. Registramos uma espécie ameaçada de extinção: Ranacephala hogei. A maior taxa de atropelamento foi registrada durante a estação chuvosa. O atropelamento de fauna é uma grande ameaça as espécies, sendo de grande importância estudos para definição de planos que busquem mitigar os efeitos gerados por esses empreendimentos.

RESUMO Objetivo: Avaliar a síndrome do doente eutireóideo como fator prognóstico em pacientes na unidade de terapia intensiva, detectar fatores que possam influenciar a mortalidade e desenvolver uma equação para calcular a probabilidade de morte. Métodos: Este foi um estudo de coorte longitudinal, observacional e não concorrente realizado na unidade de terapia intensiva da Fundação Santa Casa de Misericórdia do Pará. Realizou-se coleta de 20mL de sangue em 100 adultos sem endocrinopatia previamente documentada para a dosagem do hormônio estimulante da tireoide, da tetraiodotironina livre, da tri-iodotironina livre e da tri-iodotironina reversa. Resultados: A maioria dos pacientes era do sexo feminino, com idades entre 20 e 29 anos. A maioria dos pacientes que morreram era mais velha (idade mediana de 48 anos), e 97,5% deles possuíam a síndrome do doente eutireóideo. A síndrome do doente eutireóideo esteve relacionada à morte, às comorbidades, à idade e ao tempo de internação (mediana de 7,5 dias) na unidade de terapia intensiva. A baixa dosagem de hormônio estimulante da tireoide estava associada à morte. Os pacientes com dosagem da tri-iodotironina livre menor que 2,9pg/mL tinham maior probabilidade de morrer e, naqueles que morreram, a dosagem de tri-iodotironina reversa era maior que 0,2ng/mL. A tri-iodotironina livre apresentou maior sensibilidade e acurácia, e a tri-iodotironina reversa teve maior especificidade para prever a mortalidade. Com base nos resultados e pontos de corte, desenvolveu-se uma fórmula de regressão logística múltipla para calcular a probabilidade de morte. Conclusão: Sugere-se verificar oportunamente a dosagem da triiodotironina livre e reversa em pacientes graves e aplicar a equação proposta.

ABSTRACT Objective: To assess euthyroid sick syndrome as a prognostic factor in patients in the intensive care unit; to detect factors that may affect mortality; and to develop an equation to calculate death probability. Methods: This was a longitudinal, observational, nonconcurrent cohort study developed in the intensive care unit of Fundação Santa Casa de Misericórdia do Pará. One hundred adults with no prior documented endocrinopathy were submitted to a 20mL blood sample collection for the measurement of thyroid stimulating hormone, free tetraiodothyronine, free triiodothyronine and reverse triiodothyronine. Results: Most patients were female, aged 20 to 29 years. Most patients who died were older (median age of 48 years), and euthyroid sick syndrome was present in 97.5% of them. Euthyroid sick syndrome was related to death, comorbidities, age and length of stay in the intensive care unit (median of 7.5 days). There was an association between lower thyroid stimulating hormone and death. Patients with free triiodothyronine levels below 2.9pg/mL were more likely to die; reverse triiodothyronine rates were above 0.2ng/mL in those who died. Free triiodothyronine had greater sensitivity and accuracy, and reverse triiodothyronine had greater specificity to predict mortality. Based on the results and cutoff points, a multiple logistic regression formula was developed to calculate the probability of death. Conclusion: The main limitation of this study is the fact that it was conducted in a reference hospital for maternal and child care; therefore, there was a greater number of female patients and, consequently, a sampling bias existed. However, opportune measurement of free and reverse triiodothyronine levels in critical patients and application of the proposed equation are suggested.

Resumo Muito se tem escrito sobre a produção arquitetónica de Ludwig Mies van der Rohe, arquiteto alemão naturalizado americano, autor de algumas das mais relevantes obras de arquitetura do século XX. Mies produziu um extenso conjunto de colagens, hoje arquivadas no Museu de Arte Moderna de Nova Iorque, que revelam uma apurada estética de representação arquitetónica. A principal investigação sobre este conjunto de colagens de Mies encontra-se explanada no livro Montage Collage, de Andreas F. Beitin, Wolf Eiermann e Brigitte Franzen, que constituiu o catálogo da mostra “Mies van der Rohe: As colagens do Museu de Arte Moderna de Nova Iorque”, apresentada a 28 de outubro de 2016, no Fórum Ludwig em Aachen na Alemanha. Esta investigação ofereceu, a seu tempo, um inegável contributo para inaugurar a reflexão sobre este tema. No entanto, neste artigo centramo-nos num elemento essencial da composição, que não tem sido suficientemente estudado: as obras de arte.

Abstract A lot has been written about the architectural production of Ludwig Mies van der Rohe, German architect naturalized American who built some of the most relevant pieces of architecture of the 20th century. Mies produced an extensive amount of collages, archived today in the MoMA - Museum of Modern Art in New York, that unveil an accurate aesthetic of architectural representation. The principal investigation about this set of collages of Mies can be found in the book Montage Collage of Andreas F. Beitin, Wolf Eiermann e Brigitte Franzen, that constituted the catalogue of the exhibition Mies van der Rohe: The collages of the Museum of Modern Art in New York, presented on October 28 of 2016, in the Ludwig Fórum in Aachen, Germany. In time, they all made an undeniable contribution to start a debate on this subject. However, in this article we focus on a crucial element of the composition that has not been sufficiently studied: the works of Art.

ABSTRACT Introduction and Objective: Annually, more than one hundred thousand new stomas are created in the United States and near 30-50% of those will develop parastomal hernia (1). Occasionally parastomal hernias may result in life threatening complications such as bowel obstruction or strangulation requiring urgent surgical intervention (2). The minimally invasive surgery for these hernias are preferred, specially when the primary case was either laparoscopic or robot-assisted. Our objective is to demonstrate a step-by-step robotic approach with and without mesh placement and their outcomes in two different scenarios: elective and emergency. Materials and Methods: We present two cases, a 56-year-old male with three years prior robot-assisted radical cystectomy with ileal conduit and a 82-year-old male with five year post operation of laparoscopic radical cystectomy with bilateral ureterostomies. Both of them had parastomal hernia, the first case was an urgency due to bowel obstruction while the second case was an elective procedure. Using three portals, we choose the primary repair for the first case and placement of a biological mesh within the keyhole technique (3) for the second one. Results: In the first case we had an operative time of 110min, total blood loss of 40cc and for the second case an operative time of 140min with total blood loss of 20cc. Both patients were discharged within 24h and had a follow-up of 2 years with no recurrence. Conclusions: The capability for complex sutures and dissection of intracorporeal structures makes the robotic platform a powerful ally (4) and we believe in its superiority over conventional laparoscopy. Although further studies are required, our initial series suggests that the robotic parastomal hernia repair is feasible and reproducible, with or without mesh placement and could be demonstrated its use for either elective or emergency situations.

Resumo O trabalho desenvolveu uma pesquisa por meio de questionários online com 55 professores de educação física da rede municipal de Fortaleza/CE, atuantes nas séries de 6° a 9° ano. Objetivou analisar o conhecimento e a aplicação das leis 10.639/03 e 11.645/08. Identificou-se que a maioria dos professores não sabe do que tratam as leis. Mesmo que os docentes não tenham conhecimento, trabalham a temática étnica na escola e afirmam que o conteúdo faz parte da disciplina. Conclui-se que é preciso remodelar as práticas pedagógicas, no que tange a temática, dar uma maior atenção à formação de professores para tal assunto, diante do desafio de construírem-se caminhos para o ensino.

Abstract The work developed a research through online questionnaires with 55 Physical Education teachers of the municipal network of Fortaleza/CE, acting in the grades 6 to 9. The objective was to analyze the knowledge and application of laws 10.639/03 and 11.645/08. It has been identified that most teachers do not know what the laws are about. Even teachers who are not aware of it, work on ethnic racial issues at school, and claim that content is part of the discipline. It is concluded that it is necessary to reshape the pedagogical practices, regarding the subject matter, giving greater attention to the training of teachers for this subject, facing the challenge of constructing new avenues for teaching.

El objetivo fue analizar el conocimiento y la aplicación de las leyes 10.639/03 y 11.645/08. Se identificó que la mayoría de los profesores no sabe de qué tratan las leyes. Incluso los docentes que no tienen conocimiento trabajan la temática étnico-racial en la escuela y afirman que el contenido forma parte de la disciplina. Se concluye que es necesario remodelar las prácticas pedagógicas en lo que se refiere a la temática y hacer mayor hincapié en la formación de profesores en ese tema ante el desafío de tender nuevas vías para la enseñanza.

Abstract We present a case of atypical presentation of secondary syphilis with extensive lymph node involvement and pulmonary lesions, initially suspected as lymphoma. The patient presented with weight loss, dry cough, chest pain, palpable lymph nodes in several peripheral chains, and multiple pulmonary nodules and masses on chest imaging. The key features for secondary syphilis diagnosis were a lymph node biopsy suggestive of reactive lymphadenopathy, positive serologic tests for syphilis, and complete recovery after antisyphilitic treatment.

Abstract Aims: To analyze the prevalence of risky behaviors among physical education undergraduates; to determine prevalence of risk factors for non-communicable chronic diseases (NCCD) among university, and; to determine the association between healthy life habits and physical activity. Method: A cross-sectional study with 903 undergraduate Physical Education students. The study used a self-administered questionnaire on health-related life habits. All questions were obtained from the Surveillance of Risk and Protection Factors for Chronic Diseases through Telephone Interviews. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI). Results: Of the 903 students, 57.4% were women, 67.6% were between 20-29 years of age, 68.7% consumed alcohol, 28.5% did not do physical activity, and 33.2% were overweight. Regarding the eating habits considered a risk for NCCD, women exhibited more risk factors than men, whereas 41.1% drank more full-fat milk (p = 0.01) and 31.8% ate more fatty meats, while men drank more soda (p < 0.01). Physically active students consumed more fruits (p < 0.01) and salads (p = 0.01) and drank less soda (p < 0.01). The physically inactive students had a high prevalence of getting diabetes (p < 0.01) and of suffering from hypertension (p = 0.01) and high cholesterol (p < 0.01). Conclusions: University students in our study had unhealthy lifestyles. There is an urgent need for both a formulation and implementation of public health policies to promote health and decrease risk factors for NCCD.

ABSTRACT Introduction: Breast augmentation requires planning with objective and rigorous criteria, which were standardized by the High Five system of Tebbetts. There are a many possible combinations based on access route, implant plane, and type of implant, enabling the best outcome for each patient. Method: Of 100 patients studied, 30 received anatomic implants and 70 received round implants in the retromuscular or subglandular position, with or without round block technique. All cases used periareolar access. Preoperative evaluation was performed according to the High Five system. Results: The round block technique was used more often with anatomic implants (43%). The subglandular plane was most commonly used (76.6%). Of 30 anatomic implants, 86.7% were placed in the subglandular plane. Of 70 round implants, 71.4% were placed in the subglandular plane. There were 4 cases of grade III and IV capsular contracture, which is more common with the use of round implants. The rate of rotation among anatomic implants was 10%, with 3 cases. Conclusion: There was a low complication rate, in accordance with published data. Periareolar access provided good results in all cases. The patient should be informed about the possibility of rotation with use of anatomic implants.

RESUMO Introdução: Aumentos mamários exigem planejamento com critérios objetivos e rigorosos, que foram padronizados pelo sistema High Five, de Tebbetts. Existe um grande número de combinações possíveis, entre via de acesso, plano e tipo de implante, o que permite proporcionar o melhor resultado para cada paciente. Método: 100 pacientes operadas, 30 com implantes anatômicos e 70 com redondos, por via retromuscular ou subglandular, com a realização de roundblock ou não. Todos os casos foram operados pela via periareolar. A avaliação pré-operatória foi realizada conforme a sistematização High Five. Resultados: Roundblock foi mais utilizado no grupo de implantes anatômicos, representando 43% da amostra neste caso. O plano subglandular foi o mais utilizado, representando 76,6% da amostra total. Com relação ao implante anatômico, 86,7% dos implantes foram colocados no plano subglandular. Dos anatômicos, 71,4% foram colocados no plano subglandular. Ocorreram quatro casos de contratura capsular graus III e IV, mais comum com o uso de implante redondo. O índice de rotação do implante anatômico foi de 10%, com três casos no total. Conclusão: Ocorreu baixo índice de complicações, em conformidade com a incidência da literatura. O acesso periareolar proporcionou bons resultados em todos os casos. O paciente deve ser informado sobre a possibilidade da rotação do implante anatômico.

CONTEXTO E OBJETIVO:A torção testicular é uma emergência médica e urológica, pois pode levar à perda do órgão. A teoria da ocorrência sazonal da torção testicular é baseada em estudos de instituições localizadas em regiões frias e temperadas. O objetivo foi determinar se o clima frio está associado a uma maior incidência de torção testicular em um país tropical, como o Brasil.TIPO DE ESTUDO E LOCAL:Estudo retrospectivo, realizado em um hospital terciário e de ensino.MÉTODOS:Foram estudados pacientes com torção testicular aguda confirmada na cirurgia, durante o período de abril de 2006 a março de 2011. Informações sobre as condições climáticas no início dos sinto-mas foram coletadas.RESULTADOS:Um total de 64 casos de torção testicular foi identificado. Os meses com maiores incidên-cias foram junho (16%), julho (19%) e agosto (11%), que assinalaram as menores temperaturas médias, de 17,6 °C, 16,4 °C e 18,2 °C, respectivamente. Onze por cento dos casos ocorreram durante a primavera (outubro a dezembro), 16% no verão (janeiro a março), 34% no outono (abril a junho) e 39% no inverno (julho, agosto, setembro). Houve associação significante entre a incidência de torção testicular e a estação (outono e inverno), P < 0,001.CONCLUSÃO:Torção testicular obedece a uma predileção sazonal mesmo num país tropical, sendo mais fre-quente nos meses mais frios do ano, particularmente no outono e inverno, quando ocorrem quase três quartos dos casos. Estes achados acrescentam evidência a um papel etiológico do clima frio na torção testicular.

CONTEXT AND OBJECTIVE:Testicular torsion is a medical and urological emergency because it can lead to loss of the organ. The theory of seasonal testicular torsion occurrence is based on studies from institutions located in cold and temperate regions. The objective here was to determine whether cold weather is associated with higher incidence of testicular torsion in a tropical country, such as Brazil.DESIGN AND SETTING:Retrospective study, conducted in a tertiary and teaching hospital.METHODS:Patients with acute testicular torsion confirmed by surgery between April 2006 and March 2011 were studied. Information on weather conditions at the time of symptom onset was collected.RESULTS:A total of 64 testicular torsion cases were identified. The months with the highest incidences of testicular torsion were June (16%), July (19%) and August (11%), which had the lowest mean temperatures, of 17.6 °C, 16.4 °C and 18.2 °C, respectively. Eleven percent of cases occurred during spring (October to December), 16% occurred in summer (January to March), 34% occurred in fall (April to June) and 39% occurred in winter (July to September). There was a significant association between the incidence of testicular torsion and the season (fall and winter), P < 0.001.CONCLUSIONS:Testicular torsion follows a seasonal association even in a tropical country, and is more frequent in the colder months of the year, namely fall and winter, when almost three-quarters of the cases occurred. These observations add further evidence that cold weather has an etiologic role in testicular torsion occurrence.
