Resumo: Objetiva-se desvelar os motivos para hesitação vacinal de pais e/ou responsáveis de crianças e adolescentes para prevenção da COVID-19. Trata-se de um estudo descritivo, de abordagem qualitativa, que busca analisar as respostas da pergunta aberta “por que você não vai vacinar, não vacinou ou está na dúvida em vacinar as crianças e os adolescentes sob sua responsabilidade para prevenção da COVID-19?”. A pesquisa incluiu indivíduos adultos, brasileiros, residentes no país, responsáveis por crianças e adolescentes menores de 18 anos. A coleta de dados aconteceu de forma eletrônica entre os meses de novembro e dezembro de 2021. As respostas foram organizadas e processadas com suporte do software Iramuteq. O corpus textual desta pesquisa foi composto pela resposta de 1.896 participantes, constituído por 87% de hesitantes (1.650) e 13% (246) de pais que têm intenção de vacinar, mas que esboçaram algumas dúvidas e considerações a respeito da vacinação de crianças e adolescentes. São motivos pelos quais pais e/ou responsáveis não vacinaram ou estão na dúvida em vacinar as crianças e os adolescentes sob sua responsabilidade para prevenção da COVID-19: receio em razão de a vacina estar em fase experimental e medo das reações adversas e dos efeitos a longo prazo. Já os motivos para ausência de intenção de vacinar decorrem dos entendimentos dos participantes de que a COVID-19 em crianças não é grave, os riscos da vacinação são maiores do que os benefícios e o direito de escolha em não vacinar.

Resumen: El objetivo es revelar los motivos de la indecisión a las vacunas de padres y/o responsables de niños y adolescentes para la prevención de COVID-19. Se trata de un estudio descriptivo con enfoque cualitativo, que busca analizar las respuestas a la pregunta abierta “¿Por qué no va a vacunar o no vacunó o tiene dudas en vacunar a los niños y los adolescentes bajo su responsabilidad para la prevención del COVID-19?”. La investigación incluyó individuos adultos, brasileños, residentes en el país, responsables de niños y adolescentes menores de 18 años. La recolección de datos se realizó de forma electrónica entre los meses de noviembre y diciembre de 2021. Las respuestas se organizaron y procesaron con ayuda del software Iramuteq. El corpus textual de esta investigación fue compuesto por la respuesta de 1.896 participantes, siendo constituido por el 87% de indecisos (1.650) y el 13% (246) de padres que tienen la intención de vacunar, pero que esbozaron algunas dudas y consideraciones respecto a la vacunación de niños y adolescentes. Son motivos por los cuales los padres y/o responsables no vacunaron o están en duda en vacunar a los niños y adolescentes bajo su responsabilidad para prevención del COVID-19: temores con la vacunación en cuanto a la concepción de que la vacuna está en fase experimental, miedo a las reacciones adversas y los efectos a largo plazo. Los motivos de la ausencia de intención en vacunar se deben a que los participantes entienden que el COVID-19 en niños no es grave, que los riesgos de la vacunación son mayores que los beneficios y que tienen derecho a decidir no vacunarse.

Abstract: The objective is to unveil the reasons for vaccine hesitancy among parents and/or guardians of children and adolescents toward the prevention of COVID-19. This is a descriptive study, with a qualitative approach that seeks to analyze the answers to the open question “Why will you not vaccinate or have not vaccinated or are in doubt about vaccinating the children and adolescents under your responsibility, for the prevention of COVID-19?”. The research included adult individuals, Brazilians, living in the country, responsible for children and adolescents under 18 years of age. Data collection took place electronically in November and December 2021. The answers were organized and processed with the support of the software Iramuteq. The textual corpus of this research was composed of the response of 1,896 participants, consisting of 87% who were hesitant (1,650) and 13% (246) of parents who intend to vaccinate but who outlined some doubts and considerations about the vaccination of children and adolescents. These are reasons why parents and/or guardians have not vaccinated or are in doubt about vaccinating the children and adolescents under their responsibility for the prevention of COVID-19: fears about vaccination regarding the conception that the vaccine is in the experimental phase, fear of adverse reactions and long-term effects. The reasons for the lack of intention to vaccinate stem from the understanding of the participants that COVID-19 in children is not serious, the risks of vaccination are greater than the benefits, and the right of choice not to vaccinate.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

ABSTRACT Objective: A substantial number of people with COPD suffer from exacerbations, which are defined as an acute worsening of respiratory symptoms. To minimize exacerbations, telehealth has emerged as an alternative to improve clinical management, access to health care, and support for self-management. Our objective was to map the evidence of telehealth/telemedicine for the monitoring of adult COPD patients after hospitalization due to an exacerbation. Methods: Bibliographic search was carried in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Scopus, Biblioteca Virtual de Saúde/LILACS and Cochrane Library databases to identify articles describing telehealth and telemonitoring strategies in Portuguese, English, or Spanish published by December of 2021. Results: Thirty-nine articles, using the following concepts (number of articles), were included in this review: telehealth (21); telemonitoring (20); telemedicine (17); teleconsultation (5); teleassistance (4); telehomecare and telerehabilitation (3 each); telecommunication and mobile health (2 each); and e-health management, e-coach, telehome, telehealth care and televideo consultation (1 each). All these concepts describe strategies which use telephone and/or video calls for coaching, data monitoring, and health education leading to self-management or self-care, focusing on providing remote integrated home care with or without telemetry devices. Conclusions: This review demonstrated that telehealth/telemedicine in combination with telemonitoring can be an interesting strategy to benefit COPD patients after discharge from hospitalization for an exacerbation, by improving their quality of life and reducing re-hospitalizations, admissions to emergency services, hospital length of stay, and health care costs.

RESUMO Objetivo: Um número substancial de pessoas com DPOC sofre de exacerbações, definidas como uma piora aguda dos sintomas respiratórios. Para minimizar as exacerbações, a telessaúde surgiu como alternativa para melhorar o manejo clínico, o acesso aos cuidados de saúde e o apoio à autogestão. Nosso objetivo foi mapear as evidências de telessaúde/telemedicina para o monitoramento de pacientes adultos com DPOC após hospitalização por exacerbação. Métodos: Foi realizada uma pesquisa bibliográfica nos bancos de dados PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Scopus, Biblioteca Virtual de Saúde/LILACS e Cochrane Library para identificar artigos que descrevessem estratégias de telessaúde e telemonitoramento em português, inglês, ou espanhol, publicados até dezembro de 2021. Resultados: Trinta e nove artigos, utilizando os seguintes conceitos (número de artigos), foram incluídos nesta revisão: telessaúde (21); telemonitoramento (20); telemedicina (17); teleconsulta (5); teleassistência (4); telecuidado domiciliar e telerreabilitação (3 cada); telecomunicação e saúde móvel (2 cada); e gestão de e-saúde, e-coach, teledomicílio, cuidados de telessaúde e tele/videoconsulta (1 cada). Todos esses conceitos descrevem estratégias que utilizam chamadas telefônicas e/ou de vídeo para coaching, monitoramento de dados e educação em saúde levando à autogestão ou autocuidado, com foco na prestação de cuidados domiciliares remotos integrados, com ou sem dispositivos de telemetria. Conclusões: Esta revisão demonstrou que a telessaúde/telemedicina associada ao telemonitoramento pode ser uma estratégia interessante para beneficiar pacientes com DPOC após a alta hospitalar por exacerbação, por meio da melhora da qualidade de vida e da redução das re-hospitalizações, admissões em serviços de emergência, tempo de internação hospitalar e custos de cuidados de saúde.

Abstract The large corporations cause the most significant damages, but they can contribute to achieve the Sustainable Development Goals (SDG) and its global priorities. The purpose of this research was the map the main impacts related to SDG, analysing the business sector of Brazilian civil construction, including some of the main Brazilian companies of the following segments: construction companies, factories and cement plants, analysing their sustainability reports according to the Global Reporting Initiative (GRI) model. Only four out of the seventeen SDG were found not to be directly affected by the material aspects of the Brazilian construction industry. Therefore, suggestions were made for the mitigation of the impacts caused, including mostly governmental actions for regulation and enforcement, as well as entrepreneurial action concerning the management model. Based on the Attention-Based View theory, contributions have been suggested applicable to the companies’ management model seeking to achieve the SDG.

Resumen Las grandes corporaciones causan los daños más importantes, pero pueden contribuir al logro de los Objetivos de Desarrollo Sostenible (ODS) y sus prioridades globales. El objetivo de esta investigación fue mapear los impactos potenciales relacionados con los ODS, analizando el sector empresarial de la construcción brasileño, incluyendo algunas de las principales empresas brasileñas de los siguientes segmentos: empresas constructoras, fábricas y cementeras, analizando su Global Reporting Initiative (GRI). Identificamos que solo cuatro de los diecisiete ODS no se ven afectados directamente por los aspectos materiales del sector de construcción brasileño. Por lo tanto, hicimos sugerencias para la mitigación de los impactos causados, incluyendo especialmente medidas gubernamentales en materia de regulación e fiscalización, así como medidas empresariales relativas al modelo de gestión. Con base en la teoría de la Visión Basada en la Atención, sugerimos contribuciones aplicables al modelo de gestión de las empresas orientadas a la consecución de los ODS.

ABSTRACT Objective: to compare the effect of clinical simulation and of a lectured class on Nursing students' knowledge about the colostomy irrigation procedure. Method: a quasi-experimental study conducted in September 2019 with Nursing students attending Universidade Federal do Rio Grande do Norte in Natal, Brazil. The instruments used were a questionnaire targeted at sociodemographic issues and a knowledge analysis tool at three different moments. The Control Group had a lectured class and the Intervention Group took part in the laboratory simulation. The Chi-Square and Mann-Whitney tests were used for data analysis. Results: no statistically significant differences were observed between the groups in terms of the sociodemographic profile. In the analysis of the means of correct answers, better measures were observed in the post-test of both groups when compared to the pre-test; however, in the retention test, the students from the Intervention Group had better and statistically significant results than those from the Control Group (p-value=0.015). Conclusion: it is noticed that both teaching strategies exerted a positive effect on the students' learning process. Although both are equally important and effective, simulation showed better performance in knowledge retention. It is expected that this research enables educators to reflect on their work and allows them to use strategies that enhance their teaching practice, in order to benefit teaching and the students' development.

RESUMEN Objetivo: comparar el efecto de la simulación clínica y de una clase expositiva en los conocimientos de estudiantes de Enfermería sobre el procedimiento de irrigación de colostomía. Método: estudio cuasiexperimental realizado en septiembre de 2019 con estudiantes de Enfermería de la Universidade Federal do Rio Grande do Norte en Natal, Brasil. Como instrumentos se utilizaron un cuestionario dirigido a cuestiones sociodemográficas y una herramienta de análisis del conocimiento, en tres ocasiones diferentes. Al Grupo Control se le ofreció la clase expositiva y el Grupo Intervención participó de la simulación en laboratorio. Para el análisis de los datos se emplearon las pruebas de Chi-Cuadrado y de Mann-Whitney. Resultados: no se observaron diferencias estadísticas significativas entre los grupos en relación con el perfil sociodemográfico. En el análisis de los valores medios de respuestas correctas se observaron mejores medidas en el post-test de ambos grupos, en comparación con el pre-test; sin embargo, en el test de retención, los estudiantes del Grupo Intervención obtuvieron mejores resultados que los del Grupo Controle, además de ser estadísticamente significativos (valor p =0,015). Conclusión: se percibió que ambas estrategias de enseñanza produjeron un efecto positivo en el proceso de aprendizaje de los estudiantes. Aunque ambas son importantes y eficaces, la simulación presentó mejor desempeño en la retención de conocimientos. Se espera que este trabajo de investigación permita que los educadores reflexiones acerca de su trabajo y haga posible la utilización de estrategias que mejoren su práctica docente, a fin de beneficiar la educación y el desarrollo de los estudiantes.

RESUMO Objetivo: comparar o efeito da simulação clínica e da aula expositiva dialogada no conhecimento de estudantes de enfermagem sobre o procedimento de irrigação de colostomia. Método: estudo quase experimental, realizado em setembro de 2019 com acadêmicos de enfermagem da Universidade Federal do Rio Grande do Norte, em Natal, Brasil. Utilizaram-se como instrumentos um questionário voltado para questões sociodemográficas e um de análise de conhecimento em três diferentes ocasiões. O grupo controle teve aula expositiva dialogada e o grupo intervenção participou da simulação em laboratório. Para análise de dados foram usados os testes Qui-Quadrado e o de Mann-Whitney. Resultados: observou-se ausência de diferenças estatísticas significantes entre os grupos quanto ao perfil sociodemográfico. Na análise das médias de acertos, observaram-se melhores medidas no pós-teste dos dois grupos, quando comparado ao pré-teste, contudo, no teste de retenção os discentes do grupo intervenção tiveram resultados melhores que o grupo controle e estatisticamente significantes (p-valor=0,015). Conclusão: percebeu-se que as duas estratégias de ensino produziram efeito positivo no processo de aprendizagem dos discentes. Apesar de ambas serem importantes e eficazes, a simulação apresentou melhor desempenho na retenção do conhecimento. Espera-se que a pesquisa possibilite aos educadores a reflexão de seu trabalho e oportunize a utilização de estratégias que aprimorem sua prática docente, com vistas a beneficiar o ensino e desenvolvimento dos estudantes.

ABSTRACT. Technical and secure information on the production of quality atemoya seedlings (Annona squamosa L. x Annona cherimola Mill.) are of paramount importance due to the growing interest in this crop. This study aimed to assess the formation of atemoya seedlings propagated by grafting methods and cultivars using araticum (Annona sylvatica) rootstocks. The experiment was carried out in a screened environment at the Western Paraná State University (Unioeste), Campus of Marechal Cândido Rondon, Paraná State, Brazil. Atemoya grafts (Thompson, African Pride, and Gefner) were collected from plants from the CATI seedling nursery, located in São Bento do Sapucaí, São Paulo State, Brazil. Grafting was performed using 1-year-old araticum rootstocks with 8-10 mm in diameter at a height of 15 cm from the ground and grafts measuring, on average, 8.5 cm in length, 10 mm in diameter, and three buds. The experimental design consisted of randomized blocks in a 3 × 3 factorial arrangement (three grafting methods: cleft graft, whip and tongue graft, and chip budding × three cultivars: African Pride, Thompson, and Gefner), with four replications and 10 seedlings per replication, totaling 40 seedlings per treatment. The percentage of graft success (%), percentage of sprouting (%), number of sprouts, number of leaves, and longest sprout length (cm) were assessed at 60 days after grafting. The cleft graft method is efficient for producing atemoya seedlings. The cultivar African Pride can be grafted onto rootstocks by the cleft graft and whip and tongue graft methods, as they promote a higher percentage of graft success. The Annona sylvatica rootstock has potential for the production of atemoya seedlings, but chip budding is not viable.

Abstract The objective of this work was to evaluate the effects of additives and storage time on the quality and aerobic deterioration of silages of pineapple crop waste. A completely randomized design was used, in a 3×3 factorial arrangement, with three treatments: pineapple waste silage without additives or with the addition of cornmeal or wheat bran (20% fresh matter) at three storage times (60, 90, and 120 days). After each storage time, losses and aerobic deterioration were quantified, chemical composition was analyzed, and digestibility assays were performed. The storage time of 120 days resulted in higher dry matter losses in all treatments. The additives incremented the dry matter contents of the pineapple-based silages, which went from 182.1 g kg−1 (control silage) to 298.7 and 297.6 g kg−1 (cornmeal and wheat bran, respectively). The control silage with the addition of cornmeal showed the highest dry matter digestibility (739.7 g kg−1) and lowest neutral detergent fiber content (251.9 g kg−1). The production of CO2 started to increase on the first day of air exposure in silages without additives, but only after six days in those with additives. Including cornmeal as an additive in the silage of pineapple crop waste improves its digestibility and reduces its deterioration speed.

Resumo O objetivo deste trabalho foi avaliar os efeitos de aditivos e tempos de armazenamento sobre a qualidade e a deterioração aeróbia de silagens de resíduos de cultura do abacaxi. Utilizou-se um delineamento inteiramente casualizado, em arranjo fatorial 3×3, com três tratamentos: silagem de resíduos culturais de abacaxi sem aditivo ou aditivada com fubá de milho ou farelo de trigo (20% da matéria fresca), em três tempos de armazenamento (60, 90 e 120 dias). Após cada tempo de armazenamento, realizaram-se quantificações de perdas e deterioração aeróbia, análises da composição química e ensaios de digestibilidade. O tempo de armazenamento por 120 dias resultou em maiores perdas de matéria seca em todos os tratamentos. Os aditivos incrementaram os teores de matéria seca das silagens à base de abacaxi, que passaram de 182,1 g kg−1 (silagem controle) para 298,7 e 297,6 g kg−1 (fubá de milho e farelo de trigo, respectivamente). A silagem controle adicionada de fubá de milho apresentou maior digestibilidade da matéria seca (739,7 g kg−1) e menor teor de fibra em detergente neutro (251,9 g kg−1). A produção de CO2 aumentou a partir do primeiro dia de exposição ao ar nas silagens não aditivadas, mas apenas a partir do sexto dia nas aditivadas. A inclusão do fubá de milho como aditivo na silagem de resíduos de abacaxi melhora sua digestibilidade e reduz sua velocidade de deterioração.

ABSTRACT The objective of this study was to evaluate the effects of cocoa meal in feed concentrate on the spermatogenesis in sheep. Twenty-five uncastrated males were divided into four groups and fed concentrated feed, supplemented with 0, 10, 20, and 30% cocoa meal, respectively, for 150 days. At the end of this period, the animals were slaughtered, the testicles were collected for histological slides, and testicular morphometric assessments were conducted, including cell type quantification in the seminiferous epithelium, intrinsic spermatogenesis yield, Sertoli-cell index, total number of Sertoli cells (TNSC), TNSC per testicular gram, daily sperm production (DSP), DSP per testicular gram, testicular sperm reserve (TSR), and TSR per testicular gram. Data were subjected to normality analysis using the Shapiro-Wilk test, followed by the tests for each condition, at a significance level of 5%. The administration of cocoa meal did not alter the germinal epithelial cell population, except for the number of type-A spermatogonia, which was lower in the control group than in the group that received 20% supplementation. A difference was found in the ratio between the number of type-A spermatogonia and primary spermatocytes in pre-leptotene/leptotene, and in the ratio between Sertoli cells and primary spermatocytes in pre-leptotene/leptotene, the control group and the group that received 10% cocoa meal significantly varied from each other, but not in relation to the other evaluated percentages. The TNSC, TNSC/g, DSP, and TSR levels were diminished in the group that consumed 30% cocoa meal. The TNSC, DSP, and TSR exhibited a negative quadratic tendency. Supplementation with 10% cocoa meal improved the TNSC, DSP, and TSR of sheep.

ABSTRACT In this research, we intend to study the role of art in the creative process, in engineering courses at the Universidade Tecnológica Federal do Paraná, as a technological innovation factor. This qualitative research is characterised as a method for adopting a naturalistic and descriptive perspective. The sample is composed of students and graduates (10); teachers, coordinators and directors of Education of the Pato Branco Campus (10); Dean (1); Entrepreneurs (4). In the analysis and discussion of results from semi-structured interviews, we opted for Content Analysis, having in perspective the Theory of Social Representations of Moscovici (1978). Among the main conclusions, we highlight the valorisation of creative, interpersonal and communicative skills as fundamental competences in the formation of an engineer. It is also highlighted that the role of art in engineering can enhance creativity and constitute a factor of technological innovation. This can promote the imagination and the capacity for necessary and fundamental abstraction in the design of engineering projects and the communicational plan. The integration of art in formal training, at the moment, does not constitute an institutional option, nor does it contribute to a significant dialogical relationship between curricular activities and extracurricular artistic activities.

Resumo Este estudo apresenta a síntese de cimentos de ionômero de vidro (GIC) modificados com nanopartículas de fosfato de cálcio (nCaP). Os nCaP / GIC foram submetidos a ensaios mecânicos de compressão e tração diametral. Os biocompósitos foram caracterizados por microscopia eletrônica de varredura (MEV), espectroscopia de energia dispersiva de raios-X (EDX), difração de raios-X (XRD) e espectroscopia de infravermelho com transformada de Fourier (FTIR). Os testes de citotoxicidade e viabilidade celular foram realizados em células-tronco mesenquimais da medula óssea humana usando um ensaio de 3- (4,5-dimetiltiazol-2-il) 2,5-difeniltetrazólio-brometo e ensaios LIVE / DEAD. Diferenças estatisticamente significativas foram observadas para as propriedades mecânicas (Kruskal-Wallis, p <0,001), nCaP / GIC apresentou maior resistência à compressão e tração diametral. As análises de SEM revelaram uma distribuição uniforme de nCaP na matriz do ionômero. Os resultados de EDX e DRX indicaram fases de hidroxiapatita e β-trifosfato de cálcio. Os espectros de FTIR revelaram a banda assimétrica de ν3PO4 3- entre 1100-1030cm-1 e a banda de vibração associada a ν1PO4 3- em 963cm-1 associada a nCaP. O nCaP / GIC apresentou resposta adequada à viabilidade celular e comportamento não citotóxico. Portanto, o novo compósito nCaP / GIC apresentou ótimas propriedades mecânicas, comportamento não citotóxico e resposta adequada à viabilidade celular com promissoras aplicações odontológicas.

Abstract This study showed the synthesis of Glass ionomer cements (GIC) modified with calcium phosphate nanoparticles (nCaP). The nCaP/GIC were submitted to mechanical compression and diametral tensile tests. The biocomposite were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Cytotoxicity and cell viability tests were performed on the human bone marrow mesenchymal stem cells using a 3-(4,5-dimethylthiazol-2yl)2,5-diphenyl- tetrazolium-bromide assay and LIVE/DEAD assays. Statistically significant differences were observed for mechanical properties (Kruskal-Wallis, p<0.001), nCaP/GIC showed higher resistance to compression and diametral traction. The SEM analyses revealed a uniform distribution nCaP in the ionomer matrix. The EDX and XRD results indicated that hydroxyapatite and calcium β-triphosphate phases. The FTIR spectra revealed the asymmetric band of ν3PO43- between 1100-1030cm-1 and the vibration band associated with ν1PO43- in 963cm-1 associated with nCaP. The nCaP/GIC presented response to adequate cell viability and non-cytotoxic behavior. Therefore, the new nCaP/GIC composite showed great mechanical properties, non-cytotoxic behavior, and adequate response to cell viability with promising dental applications.

Abstract: En Pt

Objective: To describe the methodological and operational aspects of the Cancer Surveillance Project and its associated factors: population-based and hospital-based registry (VIGICAN), in Mato Grosso (MT). Methods: VIGICAN was divided into two projects: an extension one, which updated the data from the Population-Based Cancer Registry (RCBP) of MT in the period 2008 to 2016; and one of research, which collected primary data, through individual interviews and analysis of medical records of people with a diagnosis of cancer, aged 18 years or over, treated at reference hospitals for oncology. To analyze the factors associated with cancer, the following variables were collected: socioeconomic and demographic, social support, status and health behavior, and environmental exposure. Results: In the períod from 2008 to 2016, approximately one hundred thousand cases of cancer (incident and prevalent) were reported in the RCBP Cuiabá and Interior. After validation procedures, fifty thousand incident cases were chosen. The survey interviewed 1,012 patients, 38.2% living in the municipalities of Cuiabá and Várzea Grande, 60.4% in the interior of the state and 1.4% in other states. Preliminary data revealed that the majority were female (55.0%) and younger than 60 years (54.3%). Among those interviewed, 7.2% reported smoking tobacco, 15.5% consumed alcoholic beverages (15.5%) and 32.7% lived close to crops. Conclusion: The development of these projects allowed the integration of education with health services and will enable the recognition of specificities and different exposure scenarios and factors associated with cancer in the Mato Grosso territory.

Objetivo: Descrever os aspectos metodológicos e operacionais do Projeto Vigilância do Câncer e seus fatores associados: registro de base populacional e hospitalar (VIGICAN), em Mato Grosso (MT). Métodos: O VIGICAN se desdobrou em dois projetos: um de extensão, que atualizou os dados dos Registros de Câncer de Base Populacional (RCBP) de MT no período de 2008 a 2016; e um de pesquisa, que coletou dados primários, por meio de entrevistas individuais e análise de prontuários de pessoas com diagnóstico de câncer, com 18 anos ou mais, atendidas em hospitais de referência para oncologia. Para analisar os fatores associados ao câncer, foram coletadas as seguintes variáveis: socioeconômicas e demográficas, suporte social, situação e comportamentos de saúde e exposição ambiental. Resultados: No período de 2008 a 2016, foram notificados nos RCBP Cuiabá e Interior, aproximadamente, 100 mil casos de câncer (incidentes e prevalentes). Após procedimentos de validação, foram eleitos 50 mil casos incidentes. A pesquisa entrevistou 1.012 pacientes, sendo 38,2% residentes nos municípios de Cuiabá e Várzea Grande, 60,4% no interior do estado e 1,4% em outros estados. Os dados preliminares revelaram que a maioria era do sexo feminino (55,0%) e tinha menos de 60 anos (54,3%). Entre os entrevistados, 7,2% relataram fumar tabaco, 15,5% consumiam bebidas alcoólicas (15,5%) e 32,7% moravam próximos a lavouras. Conclusão: O desenvolvimento desses projetos permitiu a integração do ensino com os serviços de saúde e possibilitará o reconhecimento das especificidades e diferentes cenários de exposição e fatores associados ao câncer do território mato-grossense.

Abstract: This paper evaluates the physicochemical and biological properties of experimental resin-based dual-cured calcium aluminate (CA) and calcium titanate (CTi) materials for vital pulp therapy (VPT). The experimental dual-cured materials were obtained as two pastes: a) Bis-EMA 10, PEG 400, DHEPT, EDAB, camphorquinone, and butylated hydroxytoluene; and b) fluoride ytterbium, Bis-EMA 10, Bis-EMA 30, benzoyl peroxide, and butylated hydroxytoluene. The materials were divided into six groups based on the added calcium component: MTA (MTA®, Angelus); CLQ (Clinker-Fillapex®, Angelus); CA (calcined at ,1200°C in pastes a and b); CA800 (calcined at 800°C in paste a); CA1200 (calcined at 1,200°C in paste a); and CTi (paste a). The real-time degree of conversion and rate of polymerization (n = 3), diametral tensile strength (n = 10), hydrogen potential (n = 15), calcium ion release (n = 10), water sorption and solubility (n = 10), and cell viability (n = 6) were evaluated. One- and two-way ANOVA and Tukey’s post hoc test were used in the analysis of the parametric data, and Kruskal-Wallis and Dunn’s multiple tests were used to analyze the nonparametric data (α = 0.05). CLQ, CA800 and CA1200 had the highest diametral tensile strength. The water solubility of MTA was similar to that of CA800, CA1200 and CTi. CA800 and CA1200 resulted in cell viabilities similar to those of MTA and CLQ. The experimental dual-cured CA-based material that calcined at 800°C showed physicochemical and biological properties suitable for VPT, and similar to those of MTA.

Abstract The objective of this study was to formulate an experimental light-cured periodontal dressing containing alpha-humulene and to compare its physical, antimicrobial, and cytotoxicity properties with commercial gold standards (Barricaid® and Periobond®). Two periodontal dressing formulations were developed (a and b). The formulations were divided into 5 groups according to the alpha-humulene concentration as follows: Ea - control group, Ea1 - 1%, Ea5 - 5%, Ea10 - 10%, and Ea20 - 20%; Eb - control group, Eb1 - 1%, Eb5 - 5%, Eb10 - 10%, and Eb20 - 20%. Materials characterization was performed using the degree of conversion, cohesive strength, sorption, and solubility assays. Antimicrobial assay was performed using the modified direct contact test against E. faecalis and S. aureus. Cytotoxicity was assessed by the cell viability experiment using L929 fibroblasts. In general, the cohesive strength values of materials decreased as the alpha-humulene concentration increased. All the experimental dressings showed antimicrobial activity against both bacteria tested. Cell viability results for the Ea, Ea1, Eb, and Eb1 groups showed moderate cytotoxic effect. The formulations containing alpha-humulene showed similar behavior to the commercial references. Thus, formulations containing alpha-humulene have potential to be used as periodontal dressing.

ABSTRACT This prospective cohort study aims to analyze the surveillance of COVID-19 at a single hematopoietic stem cell transplantation (HSCT) center in Brazil, in 29 patients undergoing allogeneic HSCT and 57 healthcare workers (nurses and dentists), through viral shedding of SARS-CoV-2 in saliva and plasma and seroprevalence of anti-SARS-CoV-2 IgG. In addition, we report two cases with prolonged persistent detection of SARS-CoV-2 without seroconversion. The sample collection was performed seven times for patients and five times for healthcare workers. Only two patients tested positive for SARS-CoV-2 in their saliva and plasma samples (6.9%) without seroconversion. All healthcare workers were asymptomatic and none tested positive. Two patients (6.9%) and four nurses (8%) had positive serology. No dentists had positive viral detection or positive serology. Our results reflect a low prevalence of positive RT-PCR and seroprevalence of SARS-CoV-2 in patients and healthcare workers at a single HSCT center. Results have also corroborated how the rigorous protocols adopted in transplant centers were even more strengthened in this pandemic scenario.
