Abstract Cardiovascular diseases such as Acute Myocardial Infarction are one of the 3 leading causes of death worldwide, according to WHO data. Similarly, cardiac arrhythmias, such as atrial fibrillation, are very common diseases at present. The electrocardiogram (ECG) is the means of cardiac diagnosis that is used in a standardized way worldwide. Machine learning models are very helpful in classification and prediction problems. Applied to the field of health, artificial neural networks (ANN) and convolutional neural networks (CNN) together with tree-based models such as XGBoost, are of vital help in the prevention and control of heart diseases. The objective of the present study is to compare and evaluate the learning based on the ANN, CNN and XGBoost algorithms using the Physionet MIT-BIH and PTB ECG databases, which provide ECGs classified with Arrhythmias and Acute Myocardial Infarctions, respectively. The learning times and the percentage of Accuracy of the 3 algorithms on the 2 databases are compared separately, and finally the data are crossed to compare the validity and safety of the prediction.

Resumen Las enfermedades cardiovasculares, como el infarto agudo de miocardio, son una de las tres principales causas de muerte en el mundo según datos de la OMS. De forma similar, las arritmias cardíacas¸ como la fibrilación auricular, son enfermedades muy comunes en la actualidad. El electrocardiograma (ECG) es el medio de diagnóstico cardíaco que se utiliza de forma estandarizada en todo el mundo. Los modelos de aprendizaje automático son muy útiles en problemas de clasificación y predicción. Aplicadas al campo de la salud, las redes neuronales artificiales (ANN) y las redes neuronales convolucionales (CNN) en conjunto con modelos basados en árboles como XGBoost, son de vital ayuda en la prevención y control de enfermedades del corazón. El presente estudio tiene como objetivo comparar y evaluar el aprendizaje basado en los algoritmos ANN, CNN y XGBoost mediante el uso de las bases de datos de ECG Physionet MITBIH y PTB, que proporcionan ECG clasificados con arritmias e infartos agudos de miocardio, respectivamente. Se comparan por separado los tiempos de aprendizaje y el porcentaje de exactitud de los tres algoritmos en las dos bases de datos, y finalmente se cruzan los datos para comparar la validez y seguridad de la predicción.

Abstract This work aims to evaluate, at different stages, the productive performance, carcass quality, and intestinal biometry of European quails (Coturnix coturnix Coturnix), consuming diets with increasing levels of seaweed bran (Sargassum sp). A total of 240 European quail chicks (Coturnix coturnix Coturnix) were distributed in a completely randomized design, with four levels of bran inclusion (0.0, 2.5, 5.0, and 7.5%), 6 replications with 10 birds in each experimental plot. In the period from 1 to 21 days, the feed intake of the control group was higher, with lower water consumption. In the period from 22 to 42 days, feed and water consumption increased with the inclusion of seaweed, but with a reduction in weight gain. In the total period, water consumption was higher at the level of 2.5 and 7.5%, with lower consumption in the control group, with a small reduction in slaughter and carcass weight with the inclusion of bran. There was no difference (P > 0.05) in carcass quality and intestinal biometry. We recommended the inclusion of up to 7.5% of sargassum meal in the diet of European quails at all stages, without compromising its productive performance, carcass quality, and intestinal biometry.

Abstract The objective of this study was to evaluate the productive performance, egg quality and the morphometry of the organs of Japanese quails (Cotournix cotournix japônica) when kept in comfort and under thermal stress. 192 nine-week-old quail were used, distributed in a completely randomized design at two temperatures (T1 = 24 °C and T2 = 32 °C), with 12 replicates of eight birds each, with an experimental period of 63 days, divided into three 21-day periods. Feed intake (g fowl-1 day-1), water consumption (mL fowl-1 day-1), egg production (%), egg weight (g), egg mass (g fowl- 1 day-1) and feed conversion (kg kg-1 and kg dozen-1). Laying quails after their production cycle are marketed as beef animals. It is observed that the average final live weight was reduced (P = 0.0362) by 27.58 g in birds kept at a temperature of 32 oC, which can compromise its commercial value. The feed intake of the birds was reduced (P = 0.0051) by 14.75% with an increase in ambient temperature. Birds kept at a temperature of 32 oC for 12 h daily showed a reduction in feed intake, final weight, yolk, and gizzard weight, but without affecting egg production, weight and mass.

Abstract Objective: to assess the association between caregivers’ mental disorders and schoolchildren’s obesogenic eating behavior. Methods: cross-sectional study used a public school-based sample of children and their primary caregivers. Caregivers had to report depressive episodes or generalized anxiety disorder (GAD) during the Mini-International Neuropsychiatric Interview (MINI). Children’s obesogenic eating behavior were assessed using food responsiveness (FR) and emotional overeating (EOE) subscales of the Children’s Eating Behaviour Questionnaire (CEBQ). Bivariate analysis was conducted using the t-test, ANOVA, Pearson correlation, and adjusted linear regression model was used (including variables caregivers: sex, age, economic indicator, and schooling; schoolchildren: sex and nutritional status). Results: study includes 596 children-caregiver dyads (309 boys and 287 girls). Among caregivers, 24.7% had experienced current depressive episodes, 38.7% had past depressive episodes, and 17.2% had GAD. We observed, after adjusted analysis, that having a caregiver in a current depressive episode, increases schoolchildren’s obesogenic behavior of, for FR at 0.235 points (β=0.235; CI95%=0.022-0.449;) and EOE at 0.337 points (β=0.337; CI95%=0.162-0.512). Conclusion: caregivers’ current depressive episodes were associated with higher averages of obesogenic eating behavior (caregiver-reported), both in consuming palatable food without feeling hungry (FR) and in increasing food intake in response to negative emotions (EOE).

Resumo Objetivos: avaliar associação entre transtornos mentais do cuidador e comportamento alimentar obesogênico de escolares. Métodos: estudo transversal com amostra de crianças da rede pública de ensino e seu cuidador principal. Episódio depressivo atual e transtorno de ansiedade generalizada (TAG) do cuidador foi avaliado pela Mini-International Neuropsychiatric Interview (MINI). Comportamentos alimentares obesogênicos das crianças foi avaliado pelas subescalas resposta à comida (FR) e sobreingestão emocional (EOE) Children’s Eating Behaviour Questionnaire (CEBQ). Análise bivariada foi realizada por meio de teste-T, ANOVA e correlação de Pearson. Modelo de regressão linear ajustado (incluiu variáveis cuidadores: sexo, idade, indicador econômico e escolaridade; escolares: sexo e estado nutricional). Resultados: foram avaliadas 596 díades crianças-cuidadores (309 meninos e 287 meninas). Entre os cuidadores, 24,7% apresentaram episódio depressivo atual, 38,7% episódio depressivo passado e 17,2% TAG. Observamos, após análise ajustada, que ter um cuidador em episódio depressivo atual aumenta o comportamento obesogênico dos escolares, em 0,235 pontos para FR (β=0,235; IC95%=0,022-0,449) e em 0,337 pontos para EOE (β=0,337; IC95%=0,162-0,512). Conclusão: episódio depressivo atual do cuidador foi associado a maiores médias de comportamentos alimentares obesogênicos dos escolares, tanto no consumo de alimentos palatáveis mesmo sem fome (FR) quanto aumento da ingestão alimentar em resposta a emoções negativas (EOE).

ABSTRACT. There is currently a lack of information in the literature on the integrated production of macauba (Acrocomia aculeata) and soybean (Glycine max) crops, and the importance of expanding integrated production systems; therefore, the objective of this work was to identify the effects of macauba shading on growth, development, and productivity of different soybean cultivars. The experiment was carried out in a randomized block design in a factorial scheme (4 × 2), with four cultivars and two production systems (monoculture and crop-forest integration), and four replicates per treatment. All soybean cultivars in the crop-forest integration system showed plant stagnation due to the shade level of the palm trees, as well as a reduction in the leaf area index and chlorophyll content in the leaves. Regarding reproductive parameters, grain, and oil yield, the cultivars responded differently between the production systems, revealing an interaction between the genotype and the environment. Our methodology was not favorable to soybean production; therefore, the management of spacing between palm trees and the selection of soybean genotypes that are more adapted to shaded environments are strategies that can allow for the integrated production of these species.

ABSTRACT Macronyssid mites are ectoparasites of terrestrial vertebrates. We slide-mounted and re-examined mite material collected in a 1987-1989 expedition to Maracá Ecological Station, Roraima State, Brazil. The specimens were identified as Acanthonyssus proechimys Yunker and Saunders (Mesostigmata: Macronyssidae), which were collected parasitizing a South American spiny rat, Proechimys sp. This represents the first record of Acanthonyssus in Brazil.

RESUMO Os ácaros macronissídeos são ectoparasitas de vertebrados terrestres. Nós montamos e reexaminamos material de ácaros coletado em uma expedição entre 1987-1989 à Estação Ecológica de Maracá, Estado de Roraima, Brasil. Os espécimes foram identificados como Acanthonyssus proechimys Yunker e Saunders (Mesostigmata: Macronyssidae), que haviam sido coletados parasitando um echimídeo sul-americano, Proechimys sp. Este é o primeiro registro de Acanthonyssus no Brasil.

Biochar from slow pyrolysis under controlled conditions is favorable in the transformation of waste into materials that serve as soil conditioners, and/or environmental remediation. Thus, this work aimed to produce and characterize biochar from cassava waste under different temperature conditions and evaluate interactions with Ca2+ and Pb2+ for agricultural and environmental applications. To investigate the efficiency of the interaction of biochar with nutrients (Ca) and contaminants (Pb), the influence of pH and contact time were evaluated. There was an increase in pH, pHzpc (zero point charge), and condensed aromatic structures in BC, due to the increase in pyrolysis temperature. Also, biochar demonstrated a Pb2+ adsorbed amount of 2.03 to 2.37 mg g-1 and a Ca2+ release capacity of 0.655 to 0.765 mg g-1. In this way, biochar produced from residues of cassava waste can be a viable strategy to enhance agricultural production and reduce environmental contaminants.

Abstract This study aimed to analyze the root and root canal morphology of mandibular first and second molars using CBCT images. A total of 2,400 mandibular molars exams were selected from 600 patients aged between 18 and 75 years. The number of roots, number of root canals, and root canal configuration according to the Vertucci classification were verified. Overall, 94.92% of mandibular first molars and 90.17% of mandibular second molars had two separate roots. Among the biradicular molars, the first molars showed a greater incidence of type IV canals in the mesial root and type I in the distal root. In the second molars, the most common canal form was type IV in the mesial root and type I in the distal root. In the triradicular molars, the type IV and type I configurations were the most common in the mesial root of the first molar and second molar, respectively. In both triradicular molars, there was a prevalence of type I canal in the distal and DL roots. Statistical analysis was performed at a significance level of 0.05. The number of roots was correlated with gender (Spearman test), and the canal's configuration with gender and bilaterality (Wilcoxon test). The subpopulation studied has a high incidence of bilateral symmetry and mandibular molars with two roots with two distinct mesial canals and one distal canal. The bilateral configuration is possible to estimate the number of canals, especially in images that are difficult to visualize, such as atresic canals.

Objective: To evaluate the impact of defense mechanisms at baseline on depressive symptoms after brief psychotherapies and after 6-months of follow-up among depressed patients with and without cluster B personality disorders (PDs). Methods: This quasi-experimental study nested within a randomized clinical trial included a clinical sample of adults (18-60 years) diagnosed with major depressive disorder using the Mini-International Neuropsychiatric Interview. The Millon Clinical Multiaxial Inventory-III was applied to assess PD, the Defense Style Questionnaire 40 was used to analyze defense mechanisms, and the Beck Depression Inventory was used to measure the severity of depressive symptoms. Adjusted analysis was performed by linear regression. Results: The final sample consisted of 177 patients diagnosed with major depressive disorder, of whom 39.5% had cluster B PDs. Immature defenses at baseline significantly predicted the persistence of depressive symptoms at post-intervention and at 6-months of follow-up only in patients with PDs. Conclusion: In depressed patients with cluster B PDs, immature defenses predicted a poor response to brief therapies. The assessment of immature defenses at baseline can help identify patients at greater risk of poor therapeutic results and enable more appropriate treatment choices.

ABSTRACT The best sensorial Brown Turkey figs for the fresh market are the ones harvested soft. However, at this maturity stage, they have a very short shelf life, from two to seven days, depending on environmental conditions, which make their marketing very difficult. This research’s goal was to increase the shelf life of soft 'Roxo de Valinhos' figs, a 'Brown Turkey' plant material grown in Brazil, stored under refrigeration, by applying 1-methylcyclopropene (1-MCP), an ethylene inhibitor. Soft 'Roxo de Valinhos' figs were submitted to 1-MCP at 0; 0.5; 1.0 and 1.5 µg. L-1 for 24 h in airtight, under refrigeration at 4 ± 1 ºC. Subsequently, fruits were stored for up to 17 days at 4 ± 1 ºC. After removing from refrigerated conditions, fruits were kept for one day at room temperature (22 ºC), and then they were evaluated to determine their physical and chemical features. 1-MCP at 1.5 µg. L-1 was able to increase the soft figs shelf life to 12 days.

Resumo Objetivo: Determinar se existem diferenças entre o acompanhamento por teleconsulta e o acompanhamento habitual nos doentes com patologias crónicas, nos cuidados de saúde primários e secundários, no que concerne à redução da morbilidade e mortalidade. Fontes dos dados: MEDLINE/PubMed, NHS Evidence, The Cochrane Library e Turning Research Into Practice. Métodos: Pesquisa de estudos observacionais, ensaios clínicos e revisões sistemáticas nas línguas portuguesa e inglesa, publicados entre janeiro de 2000 e agosto de 2020, utilizando os termos MeSH Chronic Disease, Telemedicine, Remote Consultation, Primary Health Care e General Practice. Para avaliação dos níveis de evidência e da força de recomendação foi aplicada a escala Strength of Recommendation Taxonomy (SORT), da American Family Physician. Resultados: Obtiveram-se 260 estudos, dos quais apenas oito cumpriram os critérios de inclusão. Cinco dos estudos revelaram benefício significativo na morbimortalidade com o recurso a teleconsulta, face aos cuidados habituais, nomeadamente: melhoria da qualidade de vida e diminuição do número de internamentos em doentes com múltiplas comorbilidades; diminuição de sintomas álgicos e depressão associados a dor músculo-esquelética crónica; diminuição da hospitalização e mortalidade por todas as causas e diminuição de recurso a cuidados de saúde adicionais no caso da insuficiência cardíaca. Dois estudos demonstraram resultados sobreponíveis entre os doentes teleconsultados e os doentes sob cuidados habituais, relativamente ao número de exacerbações e recurso a cuidados de saúde adicionais em doentes asmáticos, número e duração de reinternamento por doença pulmonar obstrutiva crónica ou insuficiência cardíaca e na mortalidade e recursos de cuidados de saúde adicionais nos doentes com múltiplas comorbilidades. Conclusão: Esta revisão demonstrou não haver um consenso claro quanto aos resultados dos indicadores de morbimortalidade em utentes com patologias crónicas, acompanhados por teleconsulta. Ainda assim, a maioria dos estudos demonstrou benefício do uso de teleconsulta nos indicadores de morbimortalidade dos doentes acompanhados por teleconsulta relativamente aos doentes acompanhados por método habitual. Embora não consonantes, os estudos encontrados demonstraram resultados pelo menos sobreponíveis, e não inferiores, na utilização da teleconsulta quando comparada com o acompanhamento habitual dos doentes. E, considerando a qualidade dos estudos encontrados, são necessários mais estudos neste âmbito para aumentar a robustez dos resultados encontrados e permitir a generalização à prática clínica diária.

Abstract Objectives: To establish if there are differences between the use of teleconsultation and the usual care in patients with one or more chronic diseases, followed in primary or secondary healthcare, in association with the reduction of morbidity and mortality. Data sources: MEDLINE/PubMed, NHS Evidence, The Cochrane Library e Turning Research Into Practice. Methods: Search of observational studies, clinical trials, systematic reviews, and meta-analyses in Portuguese and English, published between January 2000 and August 2020 with the MeSH terms ‘Chronic Disease’, ‘Telemedicine’, ‘Remote Consultation’, ‘Primary Health Care’ and ‘General Practice’. To assess the evidence levels and recommendation importance it was used the Strength of Recommendation Taxonomy (SORT) scale of the American Family Physician. Results: Two hundred and sixty articles were obtained, of which only eight met the inclusion criteria. Five of the studies showed significant benefits in morbidity and mortality criteria, with the use of teleconsultation versus the use of usual care, such as: improvement in quality of life and a decrease in the number of hospitalizations of patients with multiple comorbidities; minimization of aching symptoms and depression, associated with chronic musculoskeletal pain; decreasing of hospitalization and mortality from all causes and reduction of the use of additional health care support in case of heart failure. Two studies showed the results between patients with access to teleconsultation and patients with usual care, in relation to the number of exacerbations, the use of additional health care assistance in asthmatic patients; number and duration of re-hospitalization in patients with chronic obstructive pulmonary disease or heart failure and concerning mortality and use of additional health care support by patients with multiple comorbidities. Conclusion: This revision showed that there is no obvious consensus regarding the results of morbidity and mortality indication criteria, in patients with chronic diseases, supported by teleconsultation. Nevertheless, the majority of the studies manifested the benefit of the use of teleconsultation in such criteria, compared to the patients supported by the usual consultation methods. Although not concordant, regarded studies demonstrated results at least overlapping, and not inferior, in the use of telemedicine when compared to the usual follow-up of patients. Even so, regarding the quality of the considered studies, there are needed more studies in this area to increase the viability of the results demonstrated, and allow the consequent generalization to the daily and normalized clinical practice.

ABSTRACT Currently, facial aesthetic changes and dissatisfaction with self-image are influences that motivate the search for quick, non-surgical and less invasive cosmetic procedures. For this reason, the demand for patients looking for orofacial aesthetic procedures is increasing. The objective of this study was List the complications resulting from orofacial harmonization procedures through a systematic literature review, identifying which types of complications and areas are most affected. The following databases were searched: Medline (PubMed), SciELO, Scopus, Cochrane, Lilacs and Web of Science, from March to September 2020, selecting the studies that presented the following inclusion criteria: original studies in humans, about complications after orofacial harmonization procedures. Thirty-three studies from the literature were selected that presented reports of complications in patients after the orofacial harmonization procedure in the forehead, nose, eyes, periocular region and lips. Even the execution of less invasive facial cosmetic procedures can cause possible immediate or late complications after the procedure, especially in the periocular region and eyes. It is important to make professionals aware of this possibility beforehand.

RESUMO Atualmente, as alterações estéticas faciais e a insatisfação com a autoimagem são influências que motivam a busca por procedimentos estéticos rápidos, não cirúrgicos e menos invasivos. Por esse motivo, a procura de pacientes que procuram por procedimentos estéticos orofaciais é crescente. O objetivo deste estudo foi elencar as complicações decorrentes dos procedimentos de harmonização orofacial por meio de uma revisão sistemática da literatura, identificando quais tipos de complicações e áreas são mais acometidas. As seguintes bases de dados foram pesquisadas: Medline (PubMed), SciELO, Scopus, Cochrane, Lilacs e Web of Science, de março a setembro de 2020, selecionando os estudos que apresentavam os seguintes critérios de inclusão: estudos originais em humanos sobre complicações após procedimentos de harmonização orofacial. Foram selecionados 33 estudos da literatura que apresentavam relatos de complicações em pacientes após o procedimento de harmonização orofacial na testa, nariz, olhos, região periocular e lábios. Mesmo a execução de procedimentos estéticos faciais menos invasivos pode acarretar possíveis complicações imediatas ou tardias após o procedimento, principalmente na região periocular e nos olhos. É importante alertar previamente os profissionais para essa possibilidade.

Abstract The circular economy, as a factor of sustainable development, is an innovative practice of resource allocation that considers the production of goods and the reuse of their waste. Society values the circular economy, since it contributes to the reduction of negative externalities arising from the operation of certain industries that generate waste that is harmful to the environment. In this work, the magnitude of the negative externality represented by the accumulation of the waste called "alperujo" in the olive sector in Chile is evaluated, identifying, and validating new businesses developed from its reuse. For this purpose, a portfolio of viable options for the valorization of alperujo was constituted, based on a contextual analysis, the application of Product-Market Fit and the participation of a focus group, which allowed estimating the reduction of the negative externality, because of the use of alperujo. This industry externality comes from the generation of 120,000 t/year of waste, with an estimated value of USD 10.48 million. The alperujo, in the form of paste or extract, can be incorporated in the production of snacks, antioxidant drinks and yogurt. The sum of the NPV of the three businesses reaches USD 11.63 million, which allows compensating the estimated negative externality with a favorable margin, using 1.8% of the alperujo generated annually in Chile. This study contributes to the validation of the circular business model in a relevant sector of the Chilean export economy.

Resumen La economía circular, como factor de desarrollo sustentable constituye una práctica innovadora de asignación de recursos, que considera la producción de bienes y la reutilización de sus residuos. La sociedad valora a la economía circular, puesto que ella contribuye a la reducción de las externalidades negativas, que surgen de la operación de determinadas industrias, generadoras de residuos, dañinos para el medio ambiente. En este trabajo, se plantea la evaluación de la magnitud de la externalidad negativa que representa la acumulación del residuo denominado “alperujo” en el sector olivícola de Chile, identificando y validando nuevos negocios desarrollados a partir de su reutilización. Para este cometido, se constituyó un portafolio de opciones viables de valorización del alperujo, a partir de un análisis contextual, la aplicación del ajuste Producto-Mercado y la participación de un focus group, lo cual permitió estimar la reducción desde la externalidad negativa, por efecto del empleo del alperujo. Esta externalidad de la industria proviene de la generación de 120.000 t/año del residuo, estimándose su valor en USD 10,48 millones. El alperujo en forma de pasta o extracto puede incorporarse en la producción de snacks, bebidas antioxidantes y yogurt. La suma de los VAN de los tres negocios alcanza a USD 11,63 millones, lo cual permite compensar con margen favorable la externalidad negativa estimada, utilizando un 1,8% del alperujo generado anualmente en Chile. Este estudio contribuye a la validación del modelo de negocio circular en un sector relevante de la economía exportadora chilena.
