Abstract: Eucalyptus planted forests contribute to maximizing lumber production but problems such as longitudinal growth strain can negatively influence the quality of the products. Knowing dendrometric variables and wood properties can help in the prediction of longitudinal growth strain, mainly with the help of artificial intelligence. Thus, the aim of this research was to evaluate the use of artificial neural networks to predict longitudinal growth strain in Eucalyptus trees based on dendrometric variables, spacing between trees and wood density. The longitudinal growth strain was measured in trees of four Eucalyptus clones planted in three spacings. The diameter and height of each tree were measured. The basic wood density was determined. Artificial neural networks were used to estimate longitudinal growth strain as a function of dendrometric variables, tree spacing and wood density. The results showed that the artificial neural networks presented good results for training and validation, with most of them resulting in high correlation coefficient values. The trained artificial neural networks showed a correlation coefficient above 0,56. Artificial neural networks showed that the variables clone and basic wood density were the ones that most contributed to the prediction of longitudinal growth strain. On the other hand, the spacing between trees, the height of the tree and the diameter at breast height were not relevant to predict growth stresses.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

The Digital Image Correlation (DIC) technique is an important method of evaluating material strain fields. Composite materials have inherently heterogeneous elastic properties, in the function of the different phases present in the composition, whereat the traditional techniques of deformation evaluation may not be sufficient to determine the mechanisms that eventually contribute to the failure of the material. The present work were evaluated, the tensile mechanical properties of polyester matrix composites loaded with an industrial residue of red mud, with a mass fraction of 20%. The properties were surveyed using the conventional technique of strain gauge and compared with the data obtained through DIC. The results showed that the DIC technique was accurate in monitoring the displacements and determining the average deformation of the tested specimens, in addition to providing ample deformation fields, for the evaluation of failure mechanisms throughout the sample request process.

ABSTRACT A considerable part of fresh plant-based food has been discarded as waste, although it could be used to make organic compost for growing plants, retaining nutrient that would be discarded without any control in the environment. The aim of this study was to produce an organic compost using fresh vegetable food discarded from restaurants and mowed grass and to evaluate it for production of lettuce. The compost was produced and mixed with the commercial substrate Tropstrato HT Hortaliças® to occupy 0, 5, 10, 15, 20 or 25% of the volume of the mixture, which was used to grow Imperial and Imperial Roxa cultivars in the first experiment, and Camila and Red Star lettuce cultivars in the second one. The experiments were conducted under protected environment, organized in a 6x2 factorial scheme, following completely randomized design with three replicates. Chemical analyses of the substrate and compost and measurements of plant size and mass were carried out. The addition of compost caused an increase in all measurements of the plant traits, with the maximum estimated increase ranging from 1.7 to 9.0 times that estimated for the absence of compost in the plant growth substrate. Maximum estimated values for size and mass were observed with compost concentrations ranging from 20.1 to 26.7% of the mixture volume. The production of organic compost and its mixture with a commercial substrate proved to be an alternative for lettuce production, giving a better destination to the organic residues and promoting a reduction in the use of industrial inputs.

RESUMO Uma parte considerável dos alimentos vegetais frescos ainda é descartada como resíduo, embora possa ser aproveitada para confecção de composto orgânico e este usado para o cultivo de plantas, retendo nutrientes que seriam dispostos sem controle no ambiente. O objetivo deste trabalho foi produzir um composto orgânico com descarte de alimentos vegetais frescos de restaurante e poda de grama e avaliá-lo para cultivo de alface. O composto foi produzido e misturado ao substrato comercial Tropstrato HT Hortaliças® de modo a ocupar 0, 5, 10, 15, 20 ou 25% do volume da mistura e ela usada para cultivo das cultivares Imperial e Imperial Roxa num primeiro experimento, e Camila e Red Star num segundo experimento. Os experimentos foram realizados em cultivo protegido em esquema fatorial 6x2, em delineamento inteiramente casualizado com três repetições. Foram realizadas análises químicas do substrato e do composto e medições de tamanho e massa das plantas. A adição de composto provocou aumento de todas as características de planta medidas, sendo que o aumento máximo estimado variou de 1,7 a 9,0 vezes aquele estimado para a ausência de composto no substrato de crescimento das plantas. Os valores máximos estimados destas características de tamanho e massa foram observados com concentrações de composto entre 20,1 e 26,7% do volume da mistura. A produção de composto orgânico e sua mistura a um substrato comercial mostrou-se uma alternativa para produção de alface, proporcionando destino adequado aos resíduos orgânicos e promovendo redução do uso de insumos industriais.

ABSTRACT The objective of this study was to determine the energy values and metabolizability of different lipid sources in the diet of Japanese quail at the laying phase. The quail were distributed in a completely randomized design with ten replications of seven poultry per treatment, totaling six treatments: basal feed (control) and basal feed containing 10% soybean oil, corn oil, canola oil, sunflower oil, and poultry fat. The values of nitrogen-corrected apparent metabolizable energy (AMEn) and the metabolizability coefficient (MC%) were evaluated. No significant difference was found between the different lipid sources for AMEn (kcal/kg) and MC (%). The value of metabolizable energy corrected for nitrogen for soybean oil was 8,790 kcal/kg; 8,773 kcal/kg for corn oil; 8,784 kcal/kg for canola oil; 8,788 kcal/kg for sunflower oil; and 8,681 kcal/kg for poultry fat in laying Japanese quail. The digestibility coefficients were 93.88% for soybean oil, 93.53% for corn oil, 93.32% for canola oil, 93.74% for sunflower oil, and 93.06% for poultry fat.

Abstract This study aims to evaluate the residual effect of different lipid sources in the diet of Japanese quails (Coturnix japonica) in the rearing phase on the performance and egg quality in the initial phase of egg-laying. In the first stage, 400 Japanese quails aged 21 days were used, being distributed in a completely randomized experimental design, with five treatments and ten replicates of eight birds/replicate Treatments consisted of basal ration (BR) with 2.5% soybean oil; BR with 2.5% corn oil; BR with 2.5% cottonseed oil; BR with 2.5% sunflower oil; and BR with 2.5% canola oil. At 42 days, maintaining the initial design, all quails received a basal ration with soybean oil, in order to evaluate the residual effect of the previous phase on the performance and egg quality in the initial phase of egg-laying (43 - 84 days). The different lipid sources did not affect the performance of quails in the initial phase of production. For egg quality, yolk height, yolk diameter, yolk index, gravity, and Haugh unit (HU) showed better results in the treatment using sunflower oil. There was a residual effect of the use of lipid sources of vegetable origin in the rearing phase diet of Japanese quails on egg quality traits. Lipid sources from soybean, corn, cottonseed, canola, and sunflower seeds can be used as energy sources in the rearing diet of egg-laying quails for not being harmful to their initial performance. The longevity in egg production of quails fed with different lipid sources in the rearing phase was similar.

Resumo A pesquisa foi conduzida com objetivo de avaliar o efeito residual de diferentes fontes lipídicas na dieta de codornas japonesas (Coturnix japonica) na fase de recria sob o desempenho e a qualidade de ovos na fase inicial de postura. Na primeira etapa foram utilizadas 400 codornas japonesas com idade de 21 dias, as aves foram distribuídas em tratamentos seguindo um delineamento inteiramente casualizado com dez repetições, de oito aves, em cinco tratamentos: ração basal (RB) com 2,5% de óleo de soja, RB com 2,5 % de óleo de milho, RB com 2,5% de óleo algodão, RB com 2,5% de óleo de girassol e RB com 2,5% de óleo de canola. Aos 42 dias mantendo o delineamento inicial, todas aves receberam ração basal com óleo de soja, para que fosse avaliado o efeito residual da fase anterior sobre o desempenho e a qualidade dos ovos na fase inicial de postura (43 - 84 dias). As diferentes fontes lipídicas não afetaram o desempenho das aves na fase inicial de produção. Para a qualidade dos ovos, os parâmetros de altura, diâmetro e índice de gema, gravidade e UH foram melhores no tratamento com utilização de óleo de girassol. Houve efeito residual da utilização de fontes lipídicas de origem vegetal na dieta em fase de recria de codornas japonesas sobre as características da qualidade dos ovos. As fontes lipídicas oriundas das sementes de soja, milho, algodão, canola e girassol podem ser utilizadas como ingredientes energéticos na dieta de recria de codornas poedeiras por nâo serem prejudiciais ao desempenho inicial das aves. A longevidade na produção dos ovos das aves alimentadas com diferentes fontes lipídicas na fase de recria foi semelhante.

ABSTRACT. The objective is to evaluate the effects of the inclusion of yerba mate in the diet on the yield and quality of chicken meat stored frozen for 120 days after slaughter. The birds were distributed in a completely randomized design, with four treatments, and eight replications with 25 birds each. The treatments consisted of providing a basal diet with 1, 2, 4, and 6 g kg-1 of ground dehydrated Yerba mate. At slaughter, temperature, pH, and carcass yield were measured. 120 days after meat freezing, measurements of pH, colorimetry, cooking weight loss (CWL), shear force, and water retention capacity were estimated. The parameters evaluated after slaughter showed regression effects on breast and drumstick temperature. Breast temperature showed a decreasing linear effect (R2=0.61). For the variable thigh temperature, there was a negative quadratic effect (R2=0.66). The quality characteristics of breast and drumstick evaluated 120 days after freezing showed an increasing linear effect of drumstick CWL (R2=0.38). Yerba mate can be included in up to 6 g kg-1 in chicken feed without changing pH, color, and meat tenderness after 120 days of freezing, maintaining carcass and cut yields.

ABSTRACT The populations of Melocactus zehntneri 'chapéu-de-frade' have shown an alarming decline due to the constant withdrawal of individuals from their natural areas. The low percentage of germination of M. zehntneri seeds, added to the slow growth, requires a system for commercial propagation of this species. This study aimed to test the influence of water, hydrochloric acid or acetic acid pre-treatments on seed germination and the influence of different substrates on the initial development of M. zehntneri seedlings. The seeds were immersed in deionized water, hydrochloric acid (5N) or glacial acetic acid (100%) for 10, 20, 30, 40 and 50 minutes and placed to germinate in a Petri dish containing filter paper moistened with 5 mL deionized water. The seedlings obtained from this germination (≡ 0.4 cm diameter) were cultivated on Carolina Soil® and vermiculite [2:1] substrates; Carolina Soil® and vermiculite [2:1] + drainage; medium-grained sand; medium-grained sand + drainage; medium-grained sand and organic compost [1:1]; medium-grained sand and organic compost [1:1] + drainage; and Carolina Soil® and medium-grained sand [1:1]. The highest percentage of germination was obtained with the pre-treatment by immersion in water, in the times of 10 and 30 minutes, totaling 55% of germinated seeds. Treatments with hydrochloric acid did not increase the percentage of germinated seeds, which were also close to 50%. In the test with the substrates, in Carolina Soil® there were the best rates of seedling survival after transplanting (87.5%) and seedling development performance. Treatments containing organic compost resulted in lower survival (69%) and seedling development. Seed germination and seedling development in Carolina Soil® substrate and sand proved to be an excellent alternative for the production of M. zehntneri seedlings.

RESUMO As populações de Melocactus zehntneri (chapéu-de-frade) têm apresentado um declínio alarmante devido à constante retirada de indivíduos de suas áreas naturais. A baixa porcentagem de germinação das sementes, somada à lentidão de crescimento, exige um sistema de propagação comercial da M. zehntneri. Este trabalho teve como objetivos testar a influência dos pré-tratamentos com água, ácido clorídrico ou ácido acético na germinação de sementes e a influência de diferentes substratos no desenvolvimento inicial de plântulas de M. zehntneri. As sementes foram imersas em água deionizada ou ácido clorídrico (5N) ou ácido acético glacial (100%) por 10, 20, 30, 40 e 50 minutos e colocadas para germinar em placas de Petri contendo papel filtro umedecido com 5 mL de água deionizada. As plântulas obtidas (≡ 0,4 cm de diâmetro) foram cultivadas em substratos Carolina Soil® e vermiculita [2:1]; Carolina Soil® e vermiculita [2:1] + drenagem; areia média; areia média + drenagem; areia média e composto orgânico [1:1]; areia média e composto orgânico [1:1] + drenagem; e Carolina Soil® e areia média [1:1]. A maior porcentagem de germinação (55%) foi obtida com o pré-tratamento por imersão em água, nos tempos de 10 e 30 minutos. Os tratamentos com ácido clorídrico não aumentaram a porcentagem de sementes germinadas, que também ficaram próximas a 50%. No teste com os substratos, em Carolina Soil® houve as melhores taxas de sobrevivência de plântulas após o transplante (87,5%) e desempenho de desenvolvimento de plântulas. Os tratamentos contendo composto orgânico resultaram em menor sobrevivência (69%) e desenvolvimento das plântulas. A germinação de sementes e o desenvolvimento de mudas em substrato Carolina Soil® e areia mostraram-se uma excelente alternativa para a produção de mudas de M. zehntneri.

Abstract Recently, the world has coped with the challenge of the novel SARS-CoV-2 rapid spreading, causing COVID-19. This scenario has overburdened health systems, forced social isolation, and interrupted some services, changing the way how health assistance is provided. The management of chronic infectious diseases such as tuberculosis is a sensitive matter in times when the control strategies are at risk. In this sense, how could a high burden disease such as tuberculosis affect or be affected when combined with the COVID-19 pandemic? Patients with tuberculosis have a social background and lung impairment that represent risks in the pandemic scenario of another widely transmitted respiratory disease. Thus, even with several questions remaining unanswered, research and public policies should be addressed to control the effects of the current highly contagious COVID-19 without forgetting how it will affect the natural progression of patients suffering from tuberculosis.

RESUMO A alface do tipo crespa, com folhas de coloração verde clara, é a hortaliça folhosa preferida no Brasil. Contudo, é relevante avaliar características agronômicas de alface com coloração verde mais intensa considerando o aumento da demanda de consumo. Dessa forma objetivou-se avaliar genótipos de alface com diferentes teores de clorofila e correlacionar com a produção de massa verde, em sistema hidropônico. Dez linhagens de alface e duas cultivares (Vanda e Luiza) foram avaliadas para características agronômicas e teores de clorofila nas folhas, em delineamento de blocos ao acaso com quatro repetições. O teor de clorofila foi variável entre os genótipos, variando de 43,3 (Luiza) a 20,8 (Vanda). Os genótipos que apresentaram maior teor de clorofila foram os que apresentaram menor produção de massa, mas não foi encontrada correlação entre essas variáveis.

ABSTRACT Crispleaf lettuce, which is a light green leaf lettuce, is the most popular leafy vegetable in Brazil. However, it is relevant to evaluate agronomic traits of lettuce with more intense green color leaves considering the increase in consumer demand. Thus, the aim of this study was to evaluate lettuce genotypes about the different chlorophyll contents and correlate with green mass production in a hydroponic system. Ten lettuce inbred lines and two cultivars (Vanda and Luiza) were evaluated for agronomic traits and chlorophyll contents in leaves. A randomized block design with four replicates was used. The chlorophyll content was variable among the genotypes, ranging from 43.3 (Luiza) to 20.8 (Vanda). The genotypes with the highest chlorophyll content were those who showed the lowest mass production, but no correlations were found between these variables, though.

Resumo Rosa é uma das flores de corte mais importantes do mundo. A micropropagação de rosas tem sido utilizada para a produção de plântulas clonais e livres de doenças e para fins de melhoramento genético. No entanto, muitas cultivares importantes de rosas apresentaram distúrbios fisiológicos em condições in vitro como senescência foliar precoce e taxa de multiplicação muito baixa. Nossa hipótese é que esses sintomas estão associados à alta sensibilidade dessas cultivares ao acúmulo de etileno no ambiente in vitro. Para o experimento foi escolhida a cultivar de rosa chamada Sena sendo essa cultivada in vitro sob diferentes concentrações de AgNO3, um inibidor da ação do etileno, e duas fontes de luz, LED e lâmpadas fluorescentes, como forma de investigar os sintomas in vitro comumente observados nesta cultivar. O AgNO3 a 1,0-2,0 mg L-1 solucionou os principais distúrbios fisiológicos observados in vitro nesta cultivar rosa. Além disso, o AgNO3 resultou na indução da floração in vitro em 50% das brotações cultivadas in vitro, utilizando a concentração de 2,0 mg L-1. Concentrações mais altas também resultaram em indução de floração, mas com desenvolvimento imperfeito de flores, como exemplo a produção de botões florais sem pétalas.

Abstract Rose is one of the most important cut flower in the world. Rose micropropagation was used for production of clonal and disease-free plantlets and to breeding purposes. However, many important rose cultivars showed physiological disorders as early-leaf senescence and very low multiplication rate under in vitro conditions. Our hypothesis is that these symptoms were associated with high sensibility of these cultivars to ethylene accumulation on in vitro environment. The rose cv. Sena was in vitro cultivated under different concentrations of AgNO3 and two light sources, LED and fluorescent lamps, as a way to investigate in vitro similar symptoms to ethylene accumulation. AgNO3 at 1.0-2.0 mg L-1 solved the main in vitro physiological disorders observed in this rose cultivar. Also, AgNO3 stimulated induction of 50% of rose shoots to in vitro flowering at 2.0 mg L-1. Higher concentrations also resulted in flowering induction, but with imperfect flower development.

Objective: Clinical and biological correlates of resilience in major depressive disorder are scarce. We aimed to investigate the effect of the Val66Met polymorphism in the BDNF gene on resilience scores in major depressive disorder patients and evaluate the polymorphism’s moderation effect on resilience scores in response to cognitive therapy. Method: A total of 106 major depressive disorder patients were enrolled in this clinical randomized study. The Resilience Scale and the Hamilton Rating Scale for Depression were applied at baseline, post-treatment, and at six months of follow-up. Blood samples were obtained at baseline for molecular analysis. Results: The baseline resilience scores were higher in patients with the Met allele (114.6±17.6) than in those with the Val/Val genotype (104.04±21.05; p = 0.037). Cognitive therapy treatment increased resilience scores (p ≤ 0.001) and decreased depressive symptoms (p ≤ 0.001). In the mixed-effect model, the Val/Val genotype represented a decrease in resilience scores (t218 = -1.98; p = 0.048), and the Val66Met polymorphism interacted with sex to predict an increase in total resilience scores during cognitive treatment (t218 = 2.69; p = 0.008). Conclusion: Our results indicate that cognitive therapy intervention could improve resilience in follow-up, considering that gender and genetic susceptibility are predicted by the Val66Met polymorphism.

ABSTRACT. This study aimed to evaluate the influence of homeopathic products in diets of quails in the egg quality when submitted to different storage periods. In the trial we used 200 Japanese quails in a completely randomized design with 4 diets: reference diet, vehicle used in homeopathic products and 2 homeopathic products - Fertsigo® and Ovosigo® with ten replicates of three eggs in each. Egg quality parameters were evaluated during 3 storage periods. Data were evaluated as repeated measures in time, the effects of the interactions between treatments and time as well as their isolated effects were verified. There was the interaction between homeopathic products and storage time in the parameters of albumen and yolk height, Haugh unit, and yolk index, in which a reduction was obtained over time. For egg weight, yolk, albumen and shell, percentage of albumen, and percentage of eggshell there was a significant effect only for homeopathy. The inclusion of homeopathic additives increased egg weight. It is indicated the addition of the product with homeopathic basis Ovosigo® and FertSigo® in diets of Japanese quails in the laying phase resulting in better egg and components but did not influence the quality maintenance of eggs of Japanese quails in the periods evaluated.

RESUMO. A esquizofrenia e os transtornos mentais comuns são uma preocupação social e econômica notável em todo o mundo. Estudos epidemiológicos sobre o impacto de transtornos mentais específicos em países emergentes são escassos. Objetivos: Nosso objetivo foi caracterizar a carga demográfica, social e econômica de pacientes com esquizofrenia e transtornos mentais comuns no sistema de saúde no Brasil. Métodos: Os dados sobre essas condições no Brasil entre 2008 e 2019 foram coletados por meio do site do Departamento de Informática do Sistema Único de Saúde (DATASUS), mantido pelo Ministério da Saúde do Brasil. As internações hospitalares anuais médias foram de 154.009,67, e a incidência acumulada de 77,44 internações por 100.000 habitantes. Resultados: As despesas hospitalares médias anuais foram de US$ 67.216.056,04, com um custo médio de internação de US$ 432,58. As faixas etárias mais afetadas foram os adultos mais velhos, embora os mais jovens tenham demonstrado tendência a aumento de ocorrências nos últimos anos. Houve um número maior de admissões entre os homens em comparação às mulheres. Conclusões: Consideramos importantes os resultados obtidos para auxiliar na avaliação e orientação de políticas públicas de prevenção e tratamento nos sistemas de saúde.

ABSTRACT. Schizophrenia and common mental disorders are noteworthy social and economic concern worldwide. Epidemiologic studies on the impact of specific mental disorders in emerging countries are scarce. Objectives: We aimed to characterize the demographic, social, and economic burden of schizophrenia and common mental disorders patients in the health system in Brazil. Methods: Data on these conditions in Brazil between 2008 and 2019 were collected through the website of the Departamento de Informática do Sistema Único de Saúde (Information Technology Department of the Unified Health System - DATASUS) maintained by the Brazilian Ministry of Health. Mean annual hospital admissions were 154,009.67, and cumulative incidence of 77.44 admissions per 100,000 inhabitants. Results: Average annual hospital expenses were US$ 67,216,056.04, with an average admission cost of US$ 432.58. The most affected age groups were older adults albeit younger individuals showed a trend towards increase of occurrences in recent years. There were a higher number of admissions in men compared to women. Conclusions: We consider the results obtained important to assist in evaluating and guiding public policies regarding the prevention and treatment in health systems.
