Abstract This study uses eye-tracking metrics to quantify the visual attention given to differentiation attributes in specialty coffees. Two Discrete Choice-type experiments were developed using the packaging as a stimulus to analyze visual attention and the probability of choice for each attribute. Experiment 1 (466 observations) included the evaluation of the attributes price, brand, coffee variety, organic label and origin. Experiment 2 (279 observations) tested price, score, altitude and roast. Experiments 1 and 2 revealed that the use of the Time Fixation Duration (TFD) and Visit Count (VC) metrics were efficient in evaluating the effect of visual attention on the choice of each attribute present in the packaging. In experiment 2, the Time to First Fixation (TFF) and the willingness-to-pay (WTP) metrics were also significant, the latter of which had a value higher than the highest price indicated by the retailer. The packaging label could be considered a first potential activation regarding the novelty that these attributes represent, and the findings of this study can direct the efforts of the coffee industry to educate its customers about the main quality attributes related to the consumption of specialty coffees that are still poorly understood, but which may generate future profitability.

Resumo Este estudo usa métricas de rastreamento ocular para quantificar a atenção visual dada aos atributos de diferenciação dos cafés especiais. Dois experimentos do tipo Discrete Choice foram desenvolvidos utilizando a embalagem como estímulo para analisar a atenção visual e a probabilidade de escolha de cada atributo. O experimento 1 (466 observações) incluiu a avaliação dos atributos preço, marca, variedade do café, selo orgânico e origem. O experimento 2 (279 observações) testou preço, pontuação, altitude e torra do grão. Os experimentos 1 e 2 revelaram que o uso das métricas Time Fixation Duration (TFD) e Visit Count (VC) foram eficientes na avaliação do efeito da atenção visual na escolha de cada atributo presente na embalagem. No experimento 2, o tempo para a primeira fixação (TFF) e as métricas de disposição a pagar (WTP) também foram significativas, sendo que este teve um valor superior ao preço mais alto indicado pelo varejista. O rótulo de uma embalagem pode ser considerado potencialmente uma primeira ativação em relação à novidade que esses atributos representam e, além disso, os achados deste estudo podem direcionar os esforços da indústria cafeeira para educar seus clientes sobre os principais atributos de qualidade relacionados ao consumo de cafés especiais que ainda são pouco conhecidos, mas que podem gerar lucratividade futura.

Objective: to analyze the correlation between time on target and glycated hemoglobin in people living with diabetes mellitus and carrying out continuous blood glucose monitoring or self-monitoring of capillary blood glucose. Method: systematic review of etiology and risk based on JBI guidelines and reported according to Preferred Reporting Items for Systematic Reviews and Meta- Analyses, covering six databases and grey literature. The sample included 16 studies and methodological quality was assessed using JBI tools. Protocol registered in the Open Science Framework, available at https://doi.org/10.17605/OSF.IO/NKMZB. Results: time on target (70-180 mg/dl) showed a negative correlation with glycated hemoglobin, while time above target (>180 mg/dl) showed a positive correlation. Correlation coefficients ranged between -0.310 and -0.869 for time on target, and between 0.66 and 0.934 for time above target. A study was carried out on a population that performed self-monitoring. Conclusion: there is a statistically significant correlation between time on target and time above target with glycated hemoglobin. The higher the proportion in the adequate glycemic range, the closer to or less than 7% the glycated hemoglobin will be. More studies are needed to evaluate this metric with data from self-monitoring of blood glucose.

Objetivo: analizar la correlación entre el tiempo en rango y la hemoglobina glicosilada de personas que viven con diabetes mellitus y realizan la monitorización continua de la glucemia o el automonitoreo de la glucemia capilar Método: revisión sistemática de etiología y riesgo basada en las directrices del JBI e informada según los Preferred Reporting Items for Systematic Reviews and Meta-Analyses, abarcando seis bases de datos y la literatura gris. La muestra incluyó 16 estudios y la calidad metodológica fue evaluada utilizando las herramientas del JBI. Protocolo registrado en Open Science Framework, disponible en https://doi.org/10.17605/OSF.IO/NKMZB. Resultados: tiempo en rango (70-180 mg/dl) mostró una correlación negativa con la hemoglobina glicosilada, mientras que el tiempo por encima del rango (>180 mg/dl) mostró una correlación positiva. Los coeficientes de correlación variaron entre -0,310 y -0,869 para el tiempo en rango, y entre 0,66 y 0,934 para el tiempo por encima del rango. Un estudio se realizó en una población que hacía el automonitoreo. Conclusión: hay una correlación estadísticamente significativa entre el tiempo en rango y el tiempo por encima del rango con la hemoglobina glicosilada. Cuanto mayor sea la proporción en el rango glucémico adecuado, más cerca o por debajo del 7% estará la hemoglobina glicosilada. Se necesitan más estudios que evalúen esta métrica con datos del automonitoreo de la glucemia.

A amostra incluiu 16 estudos e a qualidade metodológica foi avaliada utilizando as ferramentas do JBI. Registrado protocolo no Open Science Framework, disponível em https://doi.org/10.17605/OSF.IO/NKMZB. Resultados: tempo no alvo (70-180 mg/dl) apresentou correlação negativa com a hemoglobina glicada, enquanto o tempo acima do alvo (>180 mg/dl) mostrou correlação positiva. Os coeficientes de correlação variaram entre -0,310 e -0,869 para o tempo no alvo, e entre 0,66 e 0,934 para o tempo acima do alvo. Um estudo foi efetuado com população que realizava a automonitorização. Conclusão: há correlação estatisticamente significativa entre o tempo no alvo e o tempo acima do alvo com a hemoglobina glicada. Quanto maior a proporção na faixa glicêmica adequada, mais próxima ou inferior a 7% estará a hemoglobina glicada. São necessários mais estudos que avaliem essa métrica com dados da automonitorização da glicemia.

Abstract Introduction Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

RESUMO Objetivo: O objetivo deste estudo foi avaliar a toxicidade dos cimentos resinosos Rely X Ultimate 2, Rely X U200 e Variolink II, bem como sua influência na expressão de genes antioxidantes em fibroblastos gengivais humanos. Materiais e Método: Corpos de prova de cada cimento foram colocados em meio de cultura por 24 h e os extratos correspondentes foram aplicados aos fibroblastos. A viabilidade celular foi avaliada após 24, 48 e 72 h de exposição pelo ensaio de exclusão do azul de tripano e MTT. A expressão gênica foi avaliada por PCR quantitativo após 24 h de exposição aos extratos. Estes parâmetros foram comparados aos das células não expostas aos cimentos. Os dados foram submetidos ao teste ANOVA, seguido pelo pós-teste de Bonferroni (a≤0.05). Resultados: Os resultados demonstraram que todos os cimentos promoveram redução do número de células viáveis e da atividade mitocondrial nos períodos de 48 e de 72 h (p < 0,01), sendo que o Variolink II apresentou o menor efeito e os cimentos Rely X Ultimate e Rely X U200 promoveram similarmente os maiores efeitos. A análise de expressão gênica evidenciou influência significativa em todos os cimentos avaliados sobre os níveis de transcritos de PRDX1, SOD1, GPX1 e GSS (p> 0,05), com um aumento considerável no Rely X U200. Conclusão: A indução de genes antioxidantes está, pelo menos em parte, associada à citotoxicidade dos cimentos testados para a experiência de estresse oxidativo.

ABSTRACT Aim: This study evaluated cytotoxicity and antioxidant gene expression of resin cements on human gingival fibroblasts (hGF). Materials and Method: RelyX Ultimate™(RXU), Variolink™II(VLII), and RelyXU200™(RXU200) resin cements were incubated with culture medium for 24 h to obtain eluates. Then, the eluates were applied over hGF to assess cell viability at 24 h, 48 h, and 72 h and antioxidant gene expression at 24 h. hGF cultures non-exposed to the eluates were used as Control. Data were submitted to ANOVA and Bonferroni tests (α≤0.05). Results: RXU and RXU200 reduced the number of viable cells in 24 h. Longer exposure to cement extracts caused cell death. Gene expression showed peroxiredoxin 1 (PRDX1) induction by all resin cement types, and superoxide dismutase 1 (SOD1) induction by RXU200 and VLII. Moreover, RXU200 induced not only PRDX1 and SOD1, but also glutathione peroxidase 1 (GPX1), catalase (CAT), and glutathione synthetase (GSS). Conclusions: All resin cements showed toxicity, and induced antioxidant genes in hGF. Antioxidant gene induction is at least partly associated with cytotoxicity of tested cements to oxidative stress experience.

Abstract This study evaluated the effect of heating on the physicochemical properties and surface changes of tricalcium silicate sealers. Three tricalcium silicate root canal sealers (Bio-C Sealer, BioRoot-RCS, EndoSequence BC Sealer), and one epoxy resin-based sealer (AH Plus; control) were tested. The effect of heating on setting time (ST) and flowability were assessed according to ANSI/ADA 57 and ISO 6876 standards. Solubility and dimensional change (DC) of the set sealers were evaluated at 24 hours and after 30 days; the pH of the water used in the DC testing was also measured. Tests were repeated with heated sealers in an oven at 100 °C for 1 min. SEM and EDS analysis were performed. Data were analyzed using One-Way ANOVA and Tukey post-hoc tests (α=5%). Heating decreased the ST for AH Plus and EndoSequence (p<0.05). Heating reduced flowability (p<0.05) and increased pH for AH Plus (p<0.05). The solubility of Bio-C (dried specimens) was not in accordance with the ANSI/ADA standard. The solubility of EndoSequence was significantly higher (p<0.05) when it was heated and dried after 30 days. DC of Bio-C (24 h and 30 days), BioRoot-RCS (30 days) and AH Plus (24 h and 30 days) were not in accordance with the standards. SEM and EDS analysis showed significant changes in sealer microstructure after heating. In conclusion, heating decreased the ST and increased the solubility of EndoSequence BC sealer. No significant changes in flowability, DC, and pH were identified for all three tricalcium silicate sealers after heat application. However, all sealers had significant surface changes.

Resumo Este estudo avaliou o efeito do aquecimento nas propriedades físico-químicas e nas alterações superficiais de cimentos de silicato tricálcico. Três cimentos endodônticos de silicato tricálcico (Bio-C Sealer, BioRoot-RCS, EndoSequence BC Sealer) e um cimento à base de resina epóxi (AH Plus) foram testados para avaliar o efeito do aquecimento no tempo de presa (TP) e escoamento de acordo com as normas ANSI/ADA 57 e ISO 6876. A solubilidade e alteração dimensional (AD) dos cimentos foram avaliadas após 24 horas e 30 dias. O pH da água usada no teste de AD também foi medido. Os testes foram repetidos com cimentos aquecidos em um forno a 100 °C por 1 min. Análises em MEV e EDS foram realizadas. Os dados foram analisados pelos testes de ANOVA-1 via e post hoc de Tukey (α=5%). O aquecimento diminuiu o TP para AH Plus e EndoSequence (p<0,05). O aquecimento reduziu o escoamento (p<0,05) e aumentou o pH do AH Plus (p<0,05). A solubilidade do Bio-C (amostras desidratadas) não estava de acordo com o padrão ANSI/ADA. A solubilidade da EndoSequence foi significativamente maior (p<0,05) quando aquecida e desidratada após 30 dias. As AD de Bio-C (24 h e 30 dias), BioRoot-RCS (30 dias) e AH Plus (24 h e 30 dias) não estavam de acordo com as normas ADA e ISO. A análise em MEV e EDS mostrou alterações significativas na estrutura dos cimentos após aquecimento. Em conclusão, o aquecimento diminuiu o TP e aumentou a solubilidade do cimento EndoSequence BC. Não foram identificadas mudanças significativas no escoamento, AD e pH para os cimentos de silicato tricálcico após aquecimento. Porém, todos os cimentos tiveram alterações significativas na superfície.

Abstract Introduction The presentation of abstracts in a congress is an important step for the dissemination of scientific information. The American Congress of Coloproctology is promoted by the American Society of Colon & Rectal Surgeons (ASCRS), and it is the largest in number of participants within the specialty, followed by the Brazilian Congress of Coloproctology. The present study aims to evaluate variables related to the quality of the scientific production of the abstracts presented in these two events and their conversion rate to published manuscripts. Materials and Methods The present bibliometric study assesses secondary data from the review of abstracts presented in these 2 important conferences in 2016, followed by a research of the publications from these congress presentations. Results The total number of abstracts evaluated was 854. The rate of articles containing statistical analyses was of 73.7% in the American congress, and of 34.1% in the Brazilian congress. Multicentric studies were more prevalent in the American congress (23.1%). Regarding study design, the most common were case reports in the Brazilian (44.8%) congress and retrospective studies in the American congress (67.7%). As for the works presented, the rate of conversion into full manuscripts in the American congress was of 24.2% compared with 10.6% in the Brazilian congress. Most papers from the American congress (93.7%) have citations compared with 68.6% of the other event evaluated. Conclusion The scientific performance demonstrated by the conversion rate of abstracts into publications is below ideal, mainly in relation to the Brazilian meeting; yet, there were significant differences between the two events in terms of the profile of the presentations and several variables analyzed.

This work describes a green synthesis, the characterization, and biological evaluation of silver nanoparticles (AgNPs). The AgNPs suspension was synthesized using aqueous leaf extract of Eucalyptus grandis, which presented a characteristic band at 407 nm in the UV-Vis spectrum. The AgNPs presented a spherical shape and size of 9.7 ± 0.3 nm. The nanoparticles were stable over a month, indicating that E. grandis’ extract is suitable for their preparation and stabilization. The X-ray analysis showed that the crystallinity of AgNPs corresponded to the centered face phase of silver. The antibacterial and leishmanicidal activities of AgNPs were evaluated. The AgNPs presented antibacterial activity on the Gram-negative bacteria Escherichia coli at 53.9 µg mL-1. The leishmanicidal activity evaluation against promastigote forms of Leishmania infantum, Leishmania amazonensis, and Leishmania braziliensis showed that the biological response is dependent on the volume of AgNP suspension. It was demonstrated that L. infantum was more sensitive to the nanoparticle’s treatment than L. amazonensis and L. braziliensis. The treatment of L infantum promastigotes with 150 µL of AgNP suspension reduced parasite growth by 67.9%, a result which was similar to the treatment with 1 (66.7%) or 2 µL (70.6%) of amphotericin B used as a positive control.

Abstract The objective of this cross-sectional study was to investigate whether total need satisfaction and three separate basic psychological needs (autonomy, competence and relatedness) predict life skills development in dual-career athletes according to sex, type of sport, type of higher education institution and financial support. Participants included 136 Brazilian university athletes (65 boys and 71 girls) aged 17–23 years. Data collection was conducted via Basic Needs Satisfaction in Sport Scale (BNSSS) and the Life Skills Scale for Sport (LSSS). Bayesian multilevel linear regression model found that total need satisfaction and three separate basic psychological needs (autonomy, competence and relatedness) influenced life skills (teamwork, social skills, leadership, goal setting and communication) and total life skills development in dual-career athletes. Total need satisfaction influenced leadership and total life skills. Competence and relatedness influenced goal seating, social skill, leadership and total life skills. Autonomy might not have a strong correlation with life skills development dimensions standardised scores and total life skills standardised score independent of sex, type of sport, type of higher education institution and financial support. Based on such findings, satisfaction of all three basic needs combined (total need satisfaction) and separate autonomy, competence and relatedness was positively associated with the development of life skills in dual-career athletes.

Abstract Purpose To analyze the effect of national and global value chains on environmental innovation and research and development in the context of Brazilian companies listed on the Ibovespa. Theoretical framework Value chain and open innovation. Design/methodology/approach This is descriptive, documentary research that uses a quantitative approach, through the analysis of secondary data extracted from Refinitiv Eikon. The research population consisted of 70 non-financial companies listed on the Ibovespa between the years 2016 and 2020. Findings The global value chain affects environmental innovation and research and development (R&D) in a positive and significant way, revealing that companies with more evidence in their reports on formalizations with suppliers and customers show improvements in their environmental products with ecological designs and carry out more R&D spending. Those companies that have, in addition to national connections, connections with companies from other countries are more likely to have greater capacity for innovation. Practical & social implications of research The research helps in understanding how organizations can improve their value chain, considering geographic aspects and interorganizational relationships, providing more assertively innovative resources. Originality/value Although a national value chain does not influence any increase in environmental innovation, it does impact higher R&D spending. As eco-innovation involves voluntary disclosure, it is inferred that companies that are limited to maintaining relationships in Brazil do not receive the same institutional pressure, when compared to companies with a global value chain, since the latter are connected with firms in countries with greater enforcement mechanisms regarding sustainable practices.

ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização, baseada em evidências científicas, sobre cada tópico relacionado ao tratamento sistêmico e a apresentar os dados e recomendações resumidas durante a reunião. Todos os painelistas se reuniram para discutir os tópicos e elaborar as recomendações atualizadas. O presente documento é a versão final do manuscrito revisado, contendo as recomendações da SBH, e seu objetivo é auxiliar os profissionais de saúde, formuladores de políticas e planejadores no Brasil e na América Latina na tomada de decisões sobre o tratamento sistêmico de pacientes com CHC.

Resumo Objetivos analisar as concepções de pessoas que vivenciam o tratamento e o diagnóstico da tuberculose pulmonar. Método trata-se de uma pesquisa descritiva e exploratória, com abordagem qualitativa, desenvolvida em um Centro de Saúde Escola de Belém (Pará) com 30 pacientes. Os dados foram coletados durante o período de setembro de 2019 a janeiro de 2020 por meio de entrevista semiestruturada com o auxílio de um roteiro contendo seis perguntas, assim como a observação das informações contidas no prontuário e no livro de controle de registro da tuberculose. Para a análise dos resultados, foi utilizada a técnica de Análise de Conteúdo segundo a perspectiva de Bardin. Resultado identificou-se que o reduzido conhecimento sobre a doença e a presença de concepções negativas influenciam, de forma significativa, a busca por cuidados ou a adesão ao tratamento, interferindo nas atividades diárias e laborais. Conclusão conclui-se que persiste a necessidade de os doentes (res)significarem a tuberculose durante o tratamento, sendo fundamental que a equipe de saúde conheça tais concepções, a fim de subsidiar cuidados que contemplem aspectos físicos e biopsicossociais ante o Programa de Controle da Tuberculose da unidade.

Abstract Objectives to analyze the conceptions of people experiencing treatment and diagnosis of pulmonary tuberculosis. Method this is a descriptive and exploratory research with a qualitative approach, developed in a School Health Center of Belém (Pará) with 30 patients. Data was collected during the period from September 2019 to January 2020 through a semi-structured interview with the aid of a script containing six questions, as well as the observation of the information contained in the medical record and in the tuberculosis record control book. For the analysis of the results, the Content Analysis technique was used according to Bardin's perspective. Result it was identified that the reduced knowledge about the disease and the presence of negative conceptions influence, in a significant way, the search for care or the adherence to treatment, interfering in daily and work activities. Conclusion it is concluded that the need for patients to (re)mean tuberculosis during treatment persists, and it is essential that the health team knows such conceptions in order to provide care that contemplates physical and bio-psychosocial aspects before the Tuberculosis Control Program of the unit.

ABSTRACT BACKGROUND: Previous studies have shown a relationship between calf circumference (CC) and outcomes in hospitalized patients. AIMS: To investigate the relationship between CC and clinical and nutritional outcomes in older in-patients (OiP) in a surgery ward. METHODS: This was a cross-sectional study with 417 OiP in a surgery ward. Clinical variables, anthropometry, and nutritional screening instruments such as subjective global assessment (SGA), mini nutritional assessment (MNA), and nutritional risk screening (NRS) were used in the investigation. The tests Pearson’s chi-square, Mann-Whitney, Kruskal-Wallis, and Spearman’s coefficient, and multiple linear regression analyses were used to review the factors associated with CC. RESULTS: Lower CC values were found in the age group 80 years and over (p<0.0001), presence of complications (p=0.0269), NRS (p<0.0001), SGA (p<0.0001), and MNA (p<0.0001). Gender (p=0.0011; partial R2=0.01151), age (p=0.0002; partial R2=0.06032), body mass index (p≤0.0001; partial R2=0.40820), and arm circumference (p≤0.0001; partial R2=0.11890) are variables that together were associated with CC. There was also a relationship between SGA (p=0.0166; partial R2=0.00605) and absence of complications during hospitalization (p=0.0047; R2=0.01154) with CC. CONCLUSIONS: Gender, age, body mass index, and arm circumference were jointly associated with CC, in addition to SGA and absence of complications. The CC is a relevant indicator for OiP in the clinical practice.

RESUMO RACIONAL: Estudos anteriores mostraram uma relação entre a circunferência da panturrilha (CP) e desfechos em pacientes hospitalizados. OBJETIVOS: Investigar a relação entre CP e desfecho clínico e nutricional em pacientes idosos hospitalizados (PIH) em uma enfermaria cirúrgica. MÉTODOS: Este foi um estudo transversal com 417 PIH em uma enfermaria de cirurgia. Variáveis clínicas, antropometria e instrumentos de triagem nutricional como avaliação subjetiva global (ASG), mini avaliação nutricional (MAN) e triagem de risco nutricional (NRS) foram utilizados na investigação. Qui-quadrado, Mann-Whitney, Kruskal-Wallis, coeficiente de Spearman e análise de regressão linear múltipla foram usados para analisar os fatores associados a CP. RESULTADOS: Menores valores de CP foram encontrados na faixa etária de 80 anos (p<0,0001), complicações (p=0,0269), risco nutricional pelo NRS (p<0,0001), ASG (p<0,0001) e MAN (p<0,0001). Sexo (p=0,0011; R2 parcial=0,01151), idade (p=0,0002; R2 parcial=0,06032), IMC (p≤0,0001; R2 parcial=0,40820) e circunferência do braço (CB) (p≤0,0001; R2 parcial=0,11890) foram variáveis que juntas estiveram associadas com a CP. Também houve relação entre ASG (p=0,0166; R2 parcial=0,00605) e ausência de complicações durante a internação (p=0,0047; R2= 0,01154) com a CP. CONCLUSÕES: Sexo, idade, IMC e CB associaram-se conjuntamente com CP, ASG e ausência de complicações. CP é um indicador relevante em PIH na prática clínica.

ABSTRACT Afforestation of sites disturbed after bauxite mining is the favorite technique to restore all ecosystem functions. The nature of the tree species used for revegetation of post-mining land can accelerate the recovery of soil organic matter and nutrient cycles. This study aimed to determine the litterfall production, decomposition rate and nutrient content from three types of forest cover ( Eucalyptus , Anadenanthera peregrina , mixed plantation of 16 native species) planted in a bauxite mining area in recovery. Litterfall production was evaluated monthly over 30 months, and the litter mass was assessed twice a year (dry and rainy periods). Total nutrient content was determined from samples grouped by period (dry and rainy). The annual average values for litterfall dry mass and litter mass were higher in Eucalyptus and mixed native. The period (dry or rainy) did not influence litterfall rates in A. peregrina , but Eucalyptus and mixed native presented higher amounts for litterfall during the rainy and dry periods, respectively. Litter accumulation in Eucalyptus was not affected by the season of the year, but mixed native and A. peregrina presented higher litter accumulation in the dry season. Apparent decomposition rates of A. peregrina and mixed native were higher in the rainy season, highlighting the A. peregrina with the highest values compared with the other forest covers. The mixed native presented the highest leaf content of P, K, Ca and Mg in both the litterfall and litter mass, while Eucalyptus had the lowest P, K, Ca, S and N content and the highest C content in the litterfall. Litterfall production is important in degraded areas to ensure the nutrient return to the soil. The data obtained suggest that the cultivation of a mixed of 16 native trees contribute for produce the higher annual litterfall yields, besides produces leaf litterfall of better nutritional quality in relation to P, K, Ca, Mg and S. Therefore, mixed of native trees can be a promising option for reactivation of nutrient cycling and organic matter formation in mined area of bauxite in the Brazilian Atlantic Forest.
