ABSTRACT During the state of immune vulnerability in hematopoietic stem cell transplantation (HSCT), the patient has an increased risk of developing a vast number of complications, including severe problems in the oral cavity. These situations require professional oral care to act in the diagnosis and treatment of these conditions, as well as to develop prevention protocols to minimize patient's complications. Oral mucositis, opportunistic infections, bleeding, specific microbiota, taste, and salivary alterations are complications that can occur during HSCT and interfere with various aspects, such as pain control, oral intake, nutrition, bacteremia and sepsis, days of hospitalization and morbidity. Several guidelines have been published to address the role of professional oral care during the HSCT, we describe a consensus regarding these recommendations.

Abstract This study describes the hydrography and water masses of the Santos Basin Continental Shelf (SBCS) during two hydrographic campaigns (SANAGU, SANSED) in 2019. Coastal Water (CW) is the dominant water mass in the southern portion of the SBCS, with relatively low salinity values (S<35.5 g kg–1), and satellite data show that local precipitation and river discharge could not account for the low salinity observed during the cruises in the southern region of the domain. The low salinity observed is explained by the transport from the south influenced by Subtropical Shelf Water (STSW), which was influenced by the La Plata River discharge. In the northern region of the SBCS, the South Atlantic Central Water (SACW) dominates the bottom layers of the water column, with the wind playing a major role in the uplift of this water mass, as evidenced by a wind impulse analysis. In this part of the shelf, Tropical Water (TW) was the second water mass in volume and occupied the surface layers and offshore the shelf. CW is restricted to a thin surface layer, which reaches distances of a few kilometers from the coast. Our analysis show the differences in the hydrographic structure of the SBCS and suggests that the SBCS can be divided in two regions with distinct characteristics: 1) the area southwest of São Sebastião, where the hydrographic parameters were modulated by the presence of the Subtropical Shelf Water (STSW); 2) the area northeast of São Sebastião, where the uplifting of SACW was the dominant process.

ABSTRACT Objective: To investigate the impact of impaired pulmonary function on patient-centered outcomes after hospital discharge due to severe COVID-19 in patients without preexisting respiratory disease. Methods: This is an ongoing prospective cohort study evaluating patients (> 18 years of age) 2-6 months after hospital discharge due to severe COVID-19. Respiratory symptoms, health-related quality of life, lung function, and the six-minute walk test were assessed. A restrictive ventilatory defect was defined as TLC below the lower limit of normal, as assessed by plethysmography. Chest CT scans performed during hospitalization were scored for the presence and extent of parenchymal abnormalities. Results: At a mean follow-up of 17.2 ± 5.9 weeks after the diagnosis of COVID-19, 120 patients were assessed. Of those, 23 (19.2%) reported preexisting chronic respiratory diseases and presented with worse lung function and exertional dyspnea at the follow-up visit in comparison with their counterparts. When we excluded the 23 patients with preexisting respiratory disease plus another 2 patients without lung volume measurements, a restrictive ventilatory defect was observed in 42/95 patients (44%). This subgroup of patients (52.4% of whom were male; mean age, 53.9 ± 11.3 years) showed reduced resting gas exchange efficiency (DLCO), increased daily-life dyspnea, increased exertional dyspnea and oxygen desaturation, and reduced health-related quality of life in comparison with those without reduced TLC (50.9% of whom were male; mean age, 58.4 ± 11.3 years). Intensive care need and higher chest CT scores were associated with a subsequent restrictive ventilatory defect. Conclusions: The presence of a restrictive ventilatory defect approximately 4 months after severe COVID-19 in patients without prior respiratory comorbidities implies worse clinical outcomes.

RESUMO Objetivo: Investigar o impacto do comprometimento da função pulmonar nos desfechos centrados no paciente após a alta hospitalar em pacientes sem doenças respiratórias preexistentes que foram hospitalizados em virtude de COVID-19 grave. Métodos: Trata-se de um estudo prospectivo de coorte em andamento, no qual pacientes com COVID-19 grave (com idade > 18 anos) são avaliados 2-6 meses depois da alta hospitalar. Avaliamos os sintomas respiratórios, a qualidade de vida relacionada à saúde, a função pulmonar e a distância percorrida no teste de caminhada de seis minutos. A definição de distúrbio ventilatório restritivo foi CPT abaixo do limite inferior da normalidade na pletismografia. As imagens de TC de tórax realizadas durante a hospitalização foram avaliadas quanto à presença e extensão de alterações parenquimatosas. Resultados: Em média 17,2 ± 5,9 semanas depois do diagnóstico de COVID-19, foram avaliados 120 pacientes. Destes, 23 (19,2%) relataram doenças respiratórias crônicas preexistentes e apresentaram pior função pulmonar e maior dispneia aos esforços na consulta de acompanhamento quando comparados aos outros participantes. Quando excluímos os 23 pacientes com doenças respiratórias preexistentes e mais 2 pacientes (sem medidas de volumes pulmonares), observamos distúrbio ventilatório restritivo em 42/95 pacientes (44%). Esse subgrupo de pacientes (52,4% dos quais eram do sexo masculino, com média de idade de 53,9 ± 11,3 anos) apresentou menor eficiência das trocas gasosas (DLCO), maior dispneia na vida diária e dessaturação de oxigênio ao exercício e redução da qualidade de vida relacionada à saúde em comparação com aqueles sem redução da CPT (50,9% dos quais eram do sexo masculino, com média de idade de 58,4 ± 11,3 anos). A necessidade de terapia intensiva e pontuações mais altas no escore de alterações parenquimatosas na TC de tórax apresentaram relação com distúrbio ventilatório restritivo subsequente. Conclusões: A presença de distúrbio ventilatório restritivo aproximadamente 4 meses depois da COVID-19 grave em pacientes sem comorbidades respiratórias prévias implica piores desfechos clínicos.

Abstract This study compares local ecological knowledge (LEK) of fishers from the Southwest Atlantic Ocean (SWAO), Brazil, related to the franciscana dolphin (Pontoporia blainvillei). We conducted 330 ethnographic interviews in ten fishing communities in southern and southeastern Brazil between 2012 and 2018. Boolean or Classic Logic was used to identify 95 fishers who were able to recognize the franciscana dolphin accordingly to the taxonomic entity P. blainvillei: 23 in northern Espírito Santo state, one in southern Espírito Santo, 20 in northern Rio de Janeiro state, and 51 in northern Paraná state. Among these 95 fishers, 87.4% (n = 83) reported incidental captures in fishing nets. Among these, 52 (54.7%) did not know any solution to this problem. Interviews revealed that the fishers usually discard carcasses in the sea after fat and muscle tissue are removed so that they can be used as bait for shark fishing or as food. In Southeastern Brazil, fishers LEK related to their ability to identify franciscana dolphin varied from ‘no identification’ and ‘extremely low identification’ to ‘partial’ and ‘good identification,’ while in southern Brazil, fishers mainly presented a ‘good identification’ of the dolphins. We propose comanagement actions to conserve the franciscana dolphin in the SWAO.

Abstract: Introduction: At the end of 2019, one of the great challenges of the 21st century emerged, affecting the whole world. The long period in isolation made people adapt to the way they work and study, and this same measure was taken in the medical course, bringing new methodologies and learning. Objective: To analyze, through an Integrative Review, data on how the process of adapting online medical education was carried out during the pandemic. Methods: This is an Integrative Literature Review and data search was conducted in the PubMed, Virtual Health Library (BVS), Coordination for the Improvement of Higher Education Personnel (CAPES), Scientific Electronic Library Online (SCIELO) and Latin American and Caribbean Literature on Health Sciences (LILACS) databases. The search began in July 2021. Results: Initially, with the application of the inclusion criteria, a total of 841 articles were obtained from the selected databases. After excluding duplicate articles, this number was reduced to 242 articles. After applying the exclusion criteria, 22 articles were selected for the study. Conclusion: It is known that Medicine is mostly a practical course, the physical contact of students with patients is essential to develop essential skills for a quality physician, both in medical semiology techniques and in the skills necessary to establish the doctor-patient relationship. However, the need for a way of learning arose with the pandemic and teaching could not stop. In view of the points raised in the literature research, the common sense would be the application of a hybrid teaching method - online and face-to-face - (aimed at optimizing time and breaking geographic barriers, without neglecting the importance of clinical practice), exceptionally online (when there are extraordinary situations, such as the COVID-19 pandemic) or only in person (in regions where the application of e-learning is not feasible).

Resumo: Introdução: Ao final de 2019, um dos grandes desafios do século XXI veio à tona e atingiu o mundo todo. O longo período de isolamento levou as pessoas a se adaptar a uma nova forma de trabalho e estudo. A mesma medida foi adotada pelos cursos de Medicina, o que resultou em novas metodologias de aprendizagem. Objetivo: Este estudo teve como objetivo analisar, por meio de uma revisão integrativa, dados referentes ao processo de adaptação da educação médica on-line durante a pandemia. Método: Trata-se de uma revisão integrativa de literatura em que se utilizaram os dados das seguintes plataformas: PubMed, Biblioteca Virtual em Saúde (BVS), Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), Scientific Electronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). A pesquisa teve início em julho de 2021. Resultado: Inicialmente, com a aplicação dos critérios de inclusão, obteve-se um total de 841 artigos oriundos das bases de dados selecionadas. Após a exclusão de artigos duplicados, esse número foi reduzido a 242 artigos. Após a aplicação dos critérios de exclusão, chegou-se a 22 artigos selecionados para o estudo. Conclusão: Como a Medicina é um curso prático em sua maioria, é fundamental o contato físico dos estudantes com os pacientes, de modo a desenvolver habilidades essenciais para um médico de qualidade, tanto em técnicas da semiologia médica como na desenvoltura da relação médico-paciente. Porém, a necessidade de um modo de aprendizagem surgiu com a pandemia, e o ensino não podia parar. Diante dos pontos levantados na literatura pesquisada, o senso comum seria a aplicação de um método de ensino híbrido - on-line e presencial - (visando à otimização de tempo e ao rompimento de barreiras geográficas, sem deixar de lado a importância da prática clínica), excepcionalmente on-line (quando houver situações extraordinárias, a exemplo da pandemia de Covid-19) ou somente presencial (em regiões onde é inviável a aplicação do e-learning).

Abstract Objectives: Primary objectives were to analyze the prevalence of obstructive sleep apnea in (1) boys and girls, and (2) severe asthma versus moderate and mild cases. The authors hypothesized that girls and severe asthma would have a higher prevalence of obstructive sleep apnea. Methods: Cross-sectional evaluation of asthmatic children attending a tertiary Pediatric Pulmonology clinic. The authors performed a history, physical examination, pulmonary function test, and home sleep apnea test. Results: The authors studied 80 consecutive patients, 7–18 years old, mean age of 11.6 years (standard deviation 2.7), 51.3% female, and 18.5% obese. Pulmonary function tests were obtained from 80 volunteers, 45% with obstruction pattern. Home sleep apnea tests were available from 76 volunteers, with a mean obstructive respiratory index of 1.8 events/h. Obstructive sleep apnea was found in 49 volunteers (61.2%). The authors did not find associations between obstructive sleep apnea and sex or asthma severity. Conclusions: Obstructive sleep apnea was frequent among these asthmatic children. Sex and asthma severity were not risk factors. Considering the interrelationship of both diseases, it is worth keeping in mind the possibility of obstructive sleep apnea among children and teenagers with asthma.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

Abstract The objective of this work was to evaluate the application of silicate ultramafic alkaline rock, with different granulometry, as an alternative potassium source on the increase of soil fertility and on the nutritional status and biomass yield of the alfalfa and centrosema crops. The used soil was a Typic Ultisol with 27.4 mg dm-3 K and 733 g kg-1 clay. The experimental design was completely randomized, in a 4 × 2 + 1 factorial arrangement. The treatments consisted of two granulometries (<0.3 and 0.3-2.0 mm) of alkaline ultramafic rock (4.0% K2O), four K rates (0, 100, 150, and 300 mg kg-1), and an additional treatment with the application of 150 mg kg-1 K in the form of KCl (58% K2O). Both legumes were grown in a greenhouse and subjected to five successive harvests. In comparison with KCl, the application of silicate rock has the potential to increase K uptake and root and shoot dry weight yield in alfalfa and centrosema. Granulometry does not affect rock use efficiency, and alfalfa presents a better K efficiency recovery in the soil after successive harvests compared with centrosema; the inverse is observed for K use and K uptake efficiencies.

Resumo O objetivo deste trabalho foi avaliar a aplicação de rocha silicática ultramáfica alcalina com diferentes granulometrias, como fonte alternativa de potássio no aumento da fertilidade do solo e no estado nutricional e na produção de biomassa das cultura de alfafa e centrosema. O solo utilizado foi um Argissolo Amarelo distrófico com 27,4 mg dm-3 de K e 733 g kg-1 de argila. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 4 × 2 + 1. Os tratamentos consistiram em duas granulometrias (< 0,3 e 0,3-2,0 mm) da rocha ultramáfica alcalina (4,0% de K2O), na aplicação de quatro doses de K (0, 100, 150 e 300 mg kg-1) e de um tratamento adicional com a aplicação de 150 mg kg-1 de K na forma de KCl (58% de K2O). Ambas as leguminosas foram cultivadas em casa de vegetação e submetidas a cinco cortes sucessivos. Em comparação ao KCl, a aplicação da rocha silicática apresenta potencial para aumentar a absorção de K e a produção de matéria seca de raízes e da parte aérea da alfafa e da centrosema. A granulometria não altera a eficiência de uso da rocha, e a alfafa apresenta maior eficiência de recuperação de K do solo após cortes sucessivos em comparação à centrosema; o inverso é observado para eficiências de uso e absorção de K.

Abstract This study aimed to assess the cortisol, body and reproductive development of prepubertal Holstein and Holstein-Gir ¾ heifers at 27 months of age maintained in an integrated livestock-forest (ILF) system for 60 summer days compared to the monoculture system in full sun (FS). The ILF system promoted changes (P=0.02) in the cortisol levels of Holstein-Gir ¾ heifers and did not affect weight gain in any of the breed groups studied. Animals in ILF system presented a lower (P=0.006) vulvar development for the rima height parameter and similar for the vulva width parameter. The ovarian follicular population of Holstein-Gir ¾ heifers in the ILF system was lower (P=0.004); however, for the Holstein heifers, no statistical difference was found, and numbers were higher (P=0.08) in the ILF system. None of the other ovarian parameters studied had any changes, and we also found important racial differences. Weight gain (P=0.003), vulvar development (P<0.001), and mean follicular size (P=0.008) were higher in the Holstein-Gir ¾ animals. Based on such results, the effect of the ILF system at 27 months of age on stress and reproductive parameters in the Holstein breed is considered positive, although negative effects have been detected on reproductive parameters in the Holstein-Gir ¾ breed.

ABSTRACT The Brazilian Navy (BN) has its combatant force concentrated in an area with only one exit to the sea. Nevertheless, Brazil has an extensive coast that needs to be patrolled and, in case of any kind of conflict, the BN must be able to defend the sovereignty and interests of the country. For this purpose, a robust and decentralized naval force is necessary, which allows the fulfillment of its mission. This paper aims to classify the most suitable cities in Brazil to be established as naval bases by applying the ELECTRE-MOr hybrid method. Seventeen cities were analyzed, which have an opening to the sea and a pre-existing minimum port structure. The alternatives were evaluated by specialists from the BN, with more than twenty years of active service, in the light of operational, economic and strategic criteria. As a result, five alternatives were classified as the most indicated headquarters for the decentralization of the naval power: Belém/PA, São Luis/MA, Fortaleza/CE, Recife/PE and Aratu/BA. This article presents relevance to academia and society, as it represents the application of a method in the state of the art to support the decision-making process in a significant problem for the sovereignty of Brazil, presenting a methodology that can be applied in issues of tactical, operational, strategic and political levels.

ABSTRACT Marajoara Wrestling (MW) is a combat sport that has been not sufficiently investigated. Characterised as a grappling fight, MW demands peculiarities that are still not well known, such as the relationship between physical constitution and the use of competitive techniques. The present study aimed to analyse the technical-tactical performance of the MW in terms of techniques used and combat configuration. This was a cross-sectional observational study from a sample of three male athletes aged between 23 and 33 years. Athletes were filmed in a natural environment during simulated MW combat in order to raise some technical elements of the MW, such as: defensive attitudes, attack technique, takedown and ground fighting. The results allowed the following conclusions: there is no technical-tactical standard in MW, but a combination of elements involving technical-tactical collection, practice time and anthropometric indicators; temporal and functional elements are configured from one’s place of practice; the halter is the most frequent technique, being widely used when combined with other techniques; the defensive work is very similar among athletes, the same does not happen in relation to the ground fight, where differences were observed in the fight configuration. This study is expected to be useful in proposing training programs aimed at the technical-tactical performance of the MW.

RESUMO A Luta Marajoara (LM) é uma modalidade esportiva de combate ainda pouco investigada. Caracterizada como luta de agarre, a LM demanda peculiaridades ainda pouco conhecidas, como a relação entre a constituição física e uso de técnicas competitivas. O estudo tem como objetivo analisar o desempenho técnico-tático da LM em termos de técnicas utilizadas e configuração dos combates. Trata-se de um estudo transversal e observacional realizado a partir de uma amostra constituída por três atletas masculinos com idades entre 23 e 33 anos. Os atletas foram filmados em ambiente natural durante um combate simulado de LM na perspectiva de levantar alguns elementos técnicos da LM, tais como: atitudes defensivas, técnica de ataque, queda e luta de solo. Os resultados permitem as seguintes conclusões: Não existe um padrão técnico-tático em LM e sim uma combinação de elementos envolvendo, acervo técnico-tático, tempo de prática e indicadores antropométricos; Elementos temporais e funcionais são configurados a partir de seu local de prática; A cabeçada é a técnica mais frequente, sendo muito utilizada quando combinada com outras técnicas; O trabalho defensivo é muito similar entre os atletas, o mesmo não acontece em relação à luta de chão, onde se observou diferenças na configuração da luta. Espera-se que o estudo possa ser útil na proposição de programas de treinamento voltados ao desempenho técnico-tático da LM.
