Abstract Objective Evaluating job stress, job satisfaction and job motivation among operating room nurses in Brazil. Methods This was a national open-ended survey carried out between August and December 2023. The Work Satisfaction Scale (WSS), the Motivation for Work questionnaire and the Work Stress Scale (WSS) were used in an online form. Results There were a total of 385 responses, of which 160 professionals (41.6%) were nursing technicians or assistants and 225 (58.4%) were nurses. There was a high proportion of professionals with moderate to high levels of stress (72.98%), with a significant result of greater moderate to high stress in day shift professionals (p=0.01) and no difference by gender or age group. There was no statistically significant difference between the variables for technicians and nurses, nor according to the type of employment. Having two or more jobs and working daytime hours is associated with a higher perception of work-related stress. Conclusion The high proportion of nursing technicians and nurses with moderate and high stress deserves to be highlighted among the research findings.

ABSTRACT Due to the importance of grain production, and the need to work the soil under limited moisture, the aim of this study was to develop computer software to predict the tractive capacity of wheeled tractors for two types of tyre, the effect of different inflation pressures and levels of soil moisture. A mathematical model was developed to predict the tractive capacity of a 4 x 2 AFT tractor. Software was developed and tested by comparing the computational data with those from tests of a working tractor in the field. The parameters under evaluation were drawbar force and front and rear drive wheel slip. At both moisture levels, the bias tyres had the lowest front to rear slip ratio at the lower pressure; the ratios were similar when equipped with radial tyres. The bias tyres show maximum force at a slip ratio of 1.09 at the higher pressure and 1.03 at the lower, while for the radial tyres the ratio was 1.05 at the higher pressure and 1.07 at the lower. Software was developed to process data from the model, with the results used for estimating the tractive force of the tractor. The tractive force was overestimated by the model, which needs further adjustment for direct application in the field. production tyre field 109 1 09 1.0 103 03 105 05 107 07 10 0 1.

ABSTRACT A bibliometric study was undertaken to analyze the spatiotemporal distribution of works related to managing boron (B) in Eucalyptus spp. from 1970 to 2022. This analysis was based on the Web of Science and Scopus databases, and 121 documents were retrieved. The eight main aspects analyzed were (1) annual scientific production, (2) most relevant research sources, (3) world scientific production, (4) association between countries, (5) most relevant affiliations, (6) indexed terms, (7) most relevant authors, and (8) most cited documents. The results indicated that publications of studies about B in eucalyptus have increased significantly over the last decade (2010-2020). Brazil has produced the most studies relating to the nutritional management of B in eucalyptus, as is mainly reflected in the numbers of researchers, research institutions, and journals that have published on the subject. Our study found that most works have been developed regionally, with little international collaboration between countries although researchers from the United States are the most frequent partners in international collaborations. The majority of the articles analyzed focused on studying the influence of B doses on the growth and rooting of eucalyptus seedlings. Finally, one significant gap in the literature is the need for studies on sources of B via soil and leaves, and new studies on this subject should be commissioned. Thus, the bibliometric review was an efficient approach for observing the main advances in managing B in eucalyptus in recent decades and identifying the leading research groups and future opportunities for scientific advances in this area.

Se propuso el concepto de Zona de Desarrollo Próximo del Docente para describir la dinámica asimétrica que se produce entre los docentes en formación inicial y los tutores con mayor experiencia en procesos de formación. Las ZDPP han sido ampliamente mencionadas en estudios teóricos y conceptuales, pero poco exploradas empíricamente. Estudiamos cómo se da la estructuración de la ZDPP en los procesos colaborativos entre docentes y estudiantes de pregrado a partir de las discusiones en foros virtuales asociados a los cursos de formación inicial y continua. Las publicaciones se analizaron a través del análisis de contenido, centrándose en las simetrías y asimetrías existentes en los intercambios entre los diferentes participantes. Los resultados indican que participantes de todos los perfiles (estudiantes universitarios, docentes noveles o experimentados) contribuyen a la construcción del conocimiento de los demás. A partir de estos resultados, y apoyados en los conceptos de PCK y conocimiento de la práctica docente, planteamos la hipótesis interpretativa de que las ZDPP no se establecen solo como resultado de relaciones jerárquicas, sino también como resultado de los contextos específicos de las interacciones de cada grupo de participantes.

The concept of Teacher's Proximal Development Zone was proposed to describe the asymmetric dynamics that occur between teachers in initial training and tutors more experienced in training processes. ZDPP have been widely mentioned in theoretical and conceptual studies, but little explored empirically. We study how the structuring of the ZDPP occurs in the collaborative processes between teachers and undergraduates from the discussions in virtual forums associated with initial andcontinuing education courses. The posts were analyzed through content analysis, focusing on symmetries and asymmetries existing in the exchanges between distinct participants. The results indicate that participants with all profiles (undergraduates, novice or experienced teachers) contribute to the construction of knowledge of others. Based on these results, and supported by the concepts of PCK and knowledge of teaching practice, we propose the interpretative hypothesis that ZDPPs are not established only as a result of hierarchical relationships, but also as a result of the specific contexts of the interactions of each group of participants.

O conceito de Zona de Desenvolvimento Proximal do Professor foi proposto para descrever a dinâmica assimétrica que ocorre entre docentes em formação inicial e tutores mais experientes em processos formativos. As ZDPP têm sido muito mencionadas em estudos teóricos e conceituais, mas pouco exploradas empiricamente. Estudamos como ocorre a estruturação da ZDPP nos processos colaborativos entre professores e licenciandos a partir das discussões em fóruns virtuais associados a cursos de formação inicial e continuada. As postagens foram analisadas por meio de análise de conteúdo, com foco em simetrias e assimetrias existentes nas trocas entre distintos participantes. Os resultados apontam que participantes com todos os perfis (licenciandos, professores novatos ou experientes) contribuem para a construção de conhecimentos dos demais. Com base nesses resultados, e subsidiados pelos conceitos de PCK e de saberes da prática docente, propomos a hipótese interpretativa de que as ZDPPs não se estabelecem apenas em decorrência de relações hierarquizadas, mas também em decorrência dos contextos específicos das interações de cada grupo de participantes.

Abstract Objective Individuals with Down Syndrome (DS) exhibit a higher susceptibility to infections, suggesting potential immunological alterations within this population. Consequently, this study aims to assess the immune response profile in children with DS to identify potential immune dysfunctions associated with recurrent infections. Methods The authors conducted a retrospective analysis involving 49 DS patients, examining various epidemiological, clinical, cytogenetic, and laboratory variables. The studyʼs sample comprised patients aged 2-20 years, with a predominance of males. These patients were categorized into two groups based on the presence or absence of recurrent infections, as indicated by the Jeffrey Modell Foundation alert signs. Results Immunoglobulin (Ig) A, G, and M levels were deemed normal, although individuals with DS experiencing recurrent infections exhibited significantly lower IgA levels. Additionally, CD3, CD4, CD8, and CD19 lymphocyte counts were found to be within normal ranges, with no significant differences between the two groups. While overall data indicated normal seroconversion levels of pneumococcal polysaccharide antibodies, a notable impairment in seroconversion was observed among DS patients with recurrent infections compared to those without such infections. Conclusion The deficiency of anti-polysaccharide antibodies in individuals with DS may constitute an important immunological comorbidity. Therefore, it warrants further investigation, particularly among individuals with recurrent infections.

Abstract Objectives To survey, analyze and discuss the scientific evidence supporting the use of acupuncture and related techniques in the management of chronic pain in the pediatric population. Sources A survey of databases (MEDLINE, Scopus and Scielo) was carried out with search strategies, following the PRISMA statement, without limits on publication dates and languages. Clinical studies (clinical trials, single-arm, and case series) were accepted for review if they included participants aged up to 22 years. Study quality was assessed by MMAT, and the randomized clinical trial was analyzed under the STRICTA criteria. Summary of the findings 2369 articles were retrieved. After excluding repetitions, 1335 underwent the initial selection. Only 16 articles were selected for full reading, of which 5 were included in the review, being two case series, two single-arm studies, and one randomized clinical trial. The articles were considered of good quality by the adopted criteria. Conclusion The analyzed studies showed important clinical results such as the reduction of pain intensity, and improvement in school attendance and social life. However, there are many limitations in study design and sample size. Therefore, there is weak evidence to support the use of acupuncture in the context of pediatric chronic pain, but the positive results reinforce the need for further investigation of the topic with the conduct of larger and well-designed studies, to obtain more data and greater scientific conviction of the findings. population MEDLINE, MEDLINE (MEDLINE Scielo strategies statement languages trials singlearm, singlearm single arm, arm series 2 years MMAT criteria 236 retrieved repetitions 133 selection 1 reading intensity life However size Therefore welldesigned well designed 23 13

Abstract Introduction: professional codes of ethics should be updated periodically to respond to criticisms and demands arising from social, technological and scientific changes, especially in the field of human rights; Objectives: to verify the updating of the new Brazilian Code of Medical Ethics in the field of bioethics and human rights; Methods: document analysis of a document in the public domain, with previous definition of categories of analysis and registration units, with reference to the Unesco Universal Declaration of Bioethics and Human Rights. Results: the analysis showed the following most prevalent principles: dignity, autonomy, respect for human vulnerability and personal integrity, benefit and harmful effects, solidarity, privacy and confidentiality, non-discrimination and non-stigmatization; Not very well covered: people without the capacity for consent, social responsibility, protection of the environment and future generations; Absent: sharing of research benefits, equality, justice and equity, respect for cultural diversity and pluralism; Final considerations: the Brazilian Code of Medical Ethics values the maintenance of prudential autonomy in the relationship with patients and health professionals. The inclusion of broader social concerns, in a fragmentary and insufficient way, does not yet ensure the broad defense of public health, and the rights of people in vulnerability, who have historically been in a position of disparity. The application of the method in a specific context, of the pandemic, was useful for the understanding of the deontological and principlist limits applied to public health. A future revision is suggested based on Unesco's Universal Declaration of Bioethics and Human Rights and the deliberative method for interprofessional decision-making.

Resumo Introdução: os códigos profissionais de ética devem ser atualizados, periodicamente, para responder às críticas e demandas decorrentes de mudanças sociais, tecnológicas e científicas, especialmente no campo dos direitos humanos; Objetivos: verificar a atualização do novo Código de Ética Médica brasileiro ao campo da bioética e dos direitos humanos; Métodos: análise documental de documento de domínio público, com definição prévia de categorias de análise e unidades de registro, tendo como referencial teórico a Declaração Universal de Bioética e Direitos Humanos da Unesco. Resultados: a análise demonstrou como princípios mais prevalentes: dignidade, autonomia, respeito à vulnerabilidade humana e a integridade pessoal, benefício e efeitos nocivos, solidariedade, privacidade e confidencialidade, não discriminação e não estigmatização; pouco contemplados: pessoas sem capacidade de consentimento, responsabilidade social, proteção do meio ambiente e das gerações futuras; ausentes: repartição de benefícios da pesquisa, igualdade, justiça e equidade, respeito à diversidade cultural e ao pluralismo; Considerações finais: o Código de Ética Médica brasileiro preza pela manutenção de uma autonomia prudencial na relação com os pacientes e profissionais da saúde. A inclusão de preocupações sociais mais amplas, de forma fragmentária e insuficiente, não assegura ainda a ampla defesa da saúde pública, e dos direitos das pessoas em vulnerabilidade, situadas historicamente em posição de desigualdade. A aplicação do método em contexto específico, de pandemia, foi útil para a compreensão dos limites deontológicos e principialistas aplicados à saúde coletiva. Sugere-se uma futura revisão tendo como eixos a Declaração Universal de Bioética e Direitos Humanos da Unesco e o método deliberativo para tomada de decisões interprofissionais.

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12–84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19. Introdução , (DRET) COVID19.

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12–84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

Resumo Introdução: A avaliação da pressão arterial (PA) tem impacto no manejo da hipertensão arterial (HA) na doença renal crônica (DRC). O portador de DRC apresenta padrão específico de comportamento da PA ao longo da monitorização ambulatorial da pressão arterial (MAPA). Objetivos: O objetivo do corrente estudo é avaliar as associações entre os estágios progressivos da DRC e alterações da MAPA. Metodologia: Trata-se de um estudo transversal com 851 pacientes atendidos nos ambulatórios de um hospital universitário que foram submetidos ao exame de MAPA no período de janeiro de 2004 a fevereiro de 2012 para avaliar a presença e o controle da HA. Os desfechos considerados foram os parâmetros de MAPA. A variável de interesse foi o estadiamento da DRC. Foram considerados como fatores de confusão idade, sexo, índice de massa corporal, tabagismo, causa da DRC e uso de anti-hipertensivos. Resultados: A PA sistólica (PAS) se associou aos estágios 3b e 5 da DRC, independentemente das variáveis de confusão. Pressão de pulso se associou apenas ao estágio 5. O coeficiente de variação da PAS se associou progressivamente aos estágios 3a, 4 e 5, enquanto o coeficiente de variação da pressão arterial diastólica (PAD) não demonstrou associação. O descenso da PAS obteve associação com estágios 2, 4 e 5, e o descenso da PAD, com os 4 e 5. Demais parâmetros da MAPA não obtiveram associação com os estágios da DRC após os ajustes. Conclusão: Estágios mais avançados da DRC associaram-se a menor descenso noturno e a maior variabilidade da pressão arterial. Introdução (PA HA (HA .

Abstract Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM). Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM. Methodology: This is a cross-sectional study with 851 patients treated in outpatient clinics of a university hospital who underwent ABPM examination from January 2004 to February 2012 in order to assess the presence and control of AH. The outcomes considered were the ABPM parameters. The variable of interest was CKD staging. Confounding factors included age, sex, body mass index, smoking, cause of CKD, and use of antihypertensive drugs. Results: Systolic BP (SBP) was associated with CKD stages 3b and 5, irrespective of confounding variables. Pulse pressure was only associated with stage 5. The SBP coefficient of variation was progressively associated with stages 3a, 4 and 5, while the diastolic blood pressure (DBP) coefficient of variation showed no association. SBP reduction was associated with stages 2, 4 and 5, and the decline in DBP with stages 4 and 5. Other ABPM parameters showed no association with CKD stages after adjustments. Conclusion: Advanced stages of CKD were associated with lower nocturnal dipping and greater variability in blood pressure. Introduction (BP AH (AH CKD. .

SUMMARY: The anatomical structure of wood from tree species found in floodplain forests can undergo alterations due to seasonal fluctuations in water levels, potentially affecting the volume of wood available for sustainable forest management in inundated areas. Thus, this study aims to characterize the anatomical features of Hura crepitans, Ocotea cymbarum and Eschweilera albiflora, assessing whether these characteristics differ from descriptions reported in previous studies of the same species conducted in other environments. Samples were collected from six adult trees of each species in two sustainable development reserves (SDR), Mamirauá and Amanã, located in the middle Solimões region, state of Amazonas, using a non-destructive method with an increment borer. Two samples were collected from three different heights (0.30, 1.30, and 2.30 m). Microscopic descriptions of the species were determined (porosity, axial parenchyma, rays, fibers, and vessel elements). Two-way factorial ANOVA followed by Tukey’s post hoc test was used to verify the differences in the anatomical elements of the wood samples collected at the three heights. The wood of H. crepitans has diffuse porosity, a predominance of solitary vessels, diffuse-in-aggregates, scarce axial parenchyma, non-storied rays, and libriform fibers. The wood of O. cymbarum has solitary vessels in radial multiples, vasicentric axial parenchyma, non-storied rays, and septate fibers. E. albiflora has a radial grouping of vessels, banded parenchyma, and non-storied rays. This study confirms previous descriptions of this species, revealing that its anatomical characteristics remain constant throughout the trunk.

RESUMEN: La estructura anatómica de la madera de las especies de árboles que se encuentran en los bosques de llanuras aluviales puede sufrir alteraciones debido a las fluctuaciones estacionales en los niveles de agua, afectando potencialmente el volumen de madera disponible para el manejo forestal sostenible de las áreas inundadas. Así, este estudio tiene como objetivo caracterizar las características anatómicas de Hura crepitans, Ocotea cymbarum y Eschweilera albiflora, evaluando si estas características difieren de las descripciones reportadas en estudios previos de las mismas especies realizados en otros ambientes. Se recolectaron muestras de seis árboles adultos de cada especie en dos reservas de desarrollo sustentable (RDS), Mamirauá y Amanã, ubicadas en la región media de Solimões, estado de Amazonas, utilizando un método no destructivo con barrenador incremental. Se tomaron dos muestras en cada una de tres alturas diferentes (0,30, 1,30 y 2,30 m). Se determinaron descripciones microscópicas de las especies (porosidad, parénquima axial, radios, fibras y elementos de los vasos). Se utilizó ANOVA factorial de dos vías seguido de la prueba post hoc de Tukey para verificar las diferencias en los elementos anatómicos de las muestras de madera recolectadas en las tres alturas. La madera de H. crepitans tiene porosidad difusa, predominio de vasos solitarios, difusos en agregados y escaso parénquima axial, radios no estratificados y fibras libriformes. La madera de O. cymbarum tiene vasos solitarios en múltiplos radiales, parénquima axial vasicéntrico, radios sin pisos y fibras septadas. La madera de E. albiflora tiene agrupaciones radiales de vasos, parénquima bandeado y radios sin pisos. Este estudio confirma descripciones previas de la especie, revelando que las características anatómicas permanecen sustancialmente constantes en todo el tronco.

RESUMO Os percevejos-das-gramíneas [Blissus pulchellus Montandon (Hemiptera: Blissidae)] sugam a seiva de espécies forrageiras suscetíveis e injetam toxinas que destroem os vasos condutores e dificultam o transporte de água e nutrientes, levando as plantas a morte. Assim, o objetivo deste estudo foi avaliar a resistência por antixenose e tolerância em oito poáceas forrageiras à B. pulchellus e comparar as características anatômicas dos tecidos das bainhas foliares de espécies/cultivares resistentes e suscetíveis. Os ensaios foram conduzidos em laboratório e casa de vegetação, em testes com e sem chance de escolha, utilizando-se as forrageiras: Urochloa ruziziensis, U. humidicola, U. brizantha ‘Piatã’, U. brizantha ‘Paiaguás’, U. brizantha ‘Marandu’, Panicum maximum ‘Mombaça’, P. maximum ‘Zuri’, e Andropogon gayanus. Os resultados de oviposição demonstraram que no teste de escolha houve uma mudança no comportamento do percevejo em relação às gramíneas quatro horas após infestação, sendo U. humidicola, P. maximum ‘Mombaça’ e ‘Zuri’, U. brizantha ‘Marandu’ e A. gayanus menos atrativos para os insetos. Conclui-se que U. humidicola, P. maximum ‘Mombaça’ e ‘Zuri’, U. brizantha ‘Marandu’, e A. gayanus são menos atrativas a B. pulchellus. A. gayanus, e P. maximum ‘Mombaça’ e ‘Zuri’ apresentam resistência do tipo não-preferência para oviposição a B. pulchellus. A resistência de U. humidicola, P. maximum Zuri, e A. gayanus a B. pulchellus pode estar associada a maior compactação e lignificação das células dos tecidos parenquimático e esclerenquimático das bainhas foliares. percevejosdasgramíneas percevejos Blissus Hemiptera (Hemiptera Blissidae Blissidae) nutrientes morte Assim B espéciescultivares cultivares vegetação utilizandose utilizando se ruziziensis U humidicola ‘Piatã, Piatã ‘Piatã , ‘Piatã’ ‘Paiaguás, Paiaguás ‘Paiaguás ‘Paiaguás’ ‘Marandu, Marandu ‘Marandu ‘Mombaça, Mombaça ‘Mombaça P ‘Zuri, Zuri ‘Zuri infestação insetos Concluise Conclui nãopreferência não preferência

ABSTRACT Chinch bugs [Blissus pulchellus Montandon (Hemiptera: Blissidae)] suck the phloem from susceptible forage grasses, injecting toxins that destroy plant vessels and compromise the flow of water and nutrients, leading to plant death. Thus, the aim of this study was to assess eight forage grasses for antixenosis resistance to B. pulchellus and compare the anatomical characteristics of leaf sheath tissue from resistant and susceptible species/cultivars. Experiments were conducted in a laboratory and greenhouse, using choice and no-choice tests with the following forage grasses: Urochloa ruziziensis, U. humidicola, U. brizantha ‘Piatã’, U. brizantha ‘Paiaguás’, U. brizantha ‘Marandu’, Panicum maximum ‘Mombaça’, P. maximum ‘Zuri’, and Andropogon gayanus. The oviposition results demonstrated that in the choice test there was a change in the stink bug’s behavior in relation to grasses four hours after infestation, with U. humidicola, P. maximum ‘Mombaça’ and ‘Zuri’, U. brizantha ‘Marandu’ and A. gayanus, proving to be less attractive to insects. It is concluded that U. humidicola, P. maximum ‘Mombaça’ and ‘Zuri’, U. brizantha ‘Marandu’, and A. gayanus are less attractive to B. pulchellus. A. gayanus and P. maximum ‘Mombaça’ and ‘Zuri’ showed non-preference resistance (antixenosis) to oviposition by B. pulchellus. The resistance of U. humidicola, P. maximum ‘Zuri’, and A. gayanus to B. pulchellus may be associated with greater compaction and lignification of the parenchyma and sclerenchyma cells of leaf sheaths.

Resumo O uso de preservativos pode ser influenciado por aspectos psicológicos e socioculturais, que podem ser modulados por atitudes individuais. O objetivo foi propor uma versão em português brasileiro da Short-Form Condom Attitude Scale (Short-Form CAS), descrevendo os procedimentos de tradução, adaptação transcultural e avaliação das propriedades psicométricas em uma amostra de universitários. Trata-se de estudo transversal com estudantes matriculados na Universidade de São Paulo (USP), Campus Ribeirão Preto (n = 491; 61,2% feminino; média de idade: 22 anos; desvio-padrão: quatro anos). Foi realizada análise fatorial confirmatória. O modelo unifatorial com sete itens apresentou boa validade fatorial e confiabilidade, sugerindo ser a melhor solução fatorial para a Short-Form CAS. Há poucos estudos sobre os fatores comportamentais associados ao uso de preservativos em populações-chave, o que pode ser influenciado pela falta de instrumentos. A principal contribuição deste estudo foi propor uma versão simples e adaptada transculturalmente da Short-Form CAS com algumas propriedades psicométricas verificadas. Uma vez que o uso de preservativos é um componente do comportamento sexual de risco, a escala se apresenta como uma nova opção para futuros estudos na população brasileira. socioculturais individuais ShortForm Short Form CAS, , CAS) tradução universitários Tratase Trata USP, USP (USP) n 491 612 61 2 61,2 feminino idade anos desviopadrão desvio padrão desvio-padrão anos. . anos) confirmatória confiabilidade populaçõeschave, populaçõeschave populações chave, chave populações-chave instrumentos verificadas risco brasileira (USP 49 6 61, 4

Abstract The condom use can be influenced by psychological and sociocultural aspects, which can be modulated by individual’s attitudes. The aim was to propose a Brazilian Portuguese version of the Short-Form Condom Attitude Scale (Short-Form CAS), describing all procedures of translation, transcultural adaptation, and psychometric properties evaluation when applied to undergraduate students. A cross sectional study was conducted among students enrolled at University of São Paulo (USP), Campus Ribeirão Preto (n = 491; 61.2% female; average age: 22 years; standard deviation: four years). Confirmatory factor analysis was performed. A one-factor model with seven items exhibited good factorial validity and reliability, suggesting to be a better factorial solution of the Short-Form CAS in the sample. Few studies have been carried out on the behavioral factors associated with condom use in key populations, which can be exacerbated by a lack of appropriate scales. Therefore, the main contribution of the present study was to propose a simplified and transculturally adapted version of the Short-form CAS with some psychometric properties verified. Since the use of condoms is a component of the study of sexual risk behavior, this scale might be an option to be applied in various Brazilian population segments for this purpose. aspects individuals individual s attitudes ShortForm Short Form CAS, , CAS) translation adaptation USP, USP (USP) n 491 612 61 2 61.2 female age years deviation years. . years) performed onefactor one reliability sample populations scales Therefore Shortform form verified behavior purpose (USP 49 6 61. 4
