Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27–52); 55.1% were female. Regarding the “creatinine” biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were “I don’t know” (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into “knows” and “does not know” the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16–8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

Resumo Introdução: A doença renal crônica costuma ser assintomática e seu diagnóstico depende da realização de exames laboratoriais, com destaque para a creatinina sérica e pesquisa de proteinúria. Objetivo: Avaliar em uma amostra da população brasileira o conhecimento sobre o papel da creatinina sérica como marcador de função renal. Método: Estudo observacional transversal realizado na cidade de São Paulo (SP, Brasil), em que foi entrevistada uma população adulta aleatória. Resultados: Foram entrevistados 1138 indivíduos, com idade mediana de 36 anos (27–52); 55,1% do sexo feminino. Com relação ao marcador “creatinina”, 40,6% afirmaram que nunca realizaram tal dosagem. Quando questionados quanto ao conhecimento sobre a utilidade desse exame, somente 19,6% sabiam a sua função. As outras respostas foram “não sei” (71,6%), avaliar o funcionamento do coração (0,9%) e fígado (7,8%). Dos que afirmaram já terem realizado o exame de creatinina, somente 29,4% acertaram a função da creatinina. Ao dividir os grupos em “sabe” e “não sabe” a função da creatinina, percebeu-se diferença estatisticamente significante (p < 0,05) em relação ao grau de escolaridade, sexo feminino, ser aluno/trabalhador da saúde, ter dosado creatinina alguma vez, conhecer alguém com doença renal e maior idade. Na análise multivariada, a principal variável relacionada com conhecer a função da creatinina foi ter realizado o exame anteriormente (OR 5,16; IC 95% 3,16–8,43, p < 0,001). Conclusão: Há grande desconhecimento sobre a creatinina e seu uso em check-ups. Os resultados indicam que é necessário maior esforço por parte dos profissionais de saúde para divulgar o papel da creatinina sérica.

ABSTRACT BACKGROUND: The effect of weight loss (WL) on histopathological aspects of non-alcoholic fatty liver disease (NAFLD) may provide further insights into the dynamics of hepatic recovery after WL. OBJECTIVE: To analyze the effects of pre-operative WL on insulin resistance- and NAFLD-related histology in individuals undergoing bariatric surgery (BS) with or without pre-operative WL. DESIGN AND SETTING: A matched cross-sectional study was conducted at a public university hospital and a private clinic in Campinas, Brazil. METHODS: An analytical, observational, cross-sectional study was conducted using prospectively collected databases of individuals who underwent BS and liver biopsy at either a public tertiary university hospital (with pre-operative WL) or a private clinic (without pre-operative WL). Random electronic matching by gender, age, and body mass index (BMI) was performed and two paired groups of 24 individuals each were selected. RESULTS: Of the 48 participants, 75% were female. The mean age was 37.4 ± 9.6. The mean BMI was 38.9 ± 2.6 kg/m2. Fibrosis was the most common histopathological abnormality (91.7%). Glucose was significantly lower in the WL group (92 ± 19.1 versus 111.8 ± 35.4 mg/dL; P = 0.02). Significantly lower frequencies of macrovesicular steatosis (58.3% versus 95.8%; P = 0.004), microvesicular steatosis (12.5% versus 87.5%; P < 0.001), and portal inflammation (50% versus 87.5%; P = 0.011) were observed in the WL group. CONCLUSION: Pre-operative WL was significantly associated with lower frequencies of macro- and mi- crovesicular steatosis, portal inflammation, and lower glycemia, indicating an association between the recent trajectory of body weight and histological aspects of NAFLD.

Abstract The aim of this study was to analyze the expression of mast cell markers toluidine blue, c-kit, and tryptase and presence of mononuclear inflammatory cells in oral lichen planus (OLP) and oral lichenoid lesions related to dental amalgam. Nineteen specimens of OLP, OLLC, and healthy oral mucosa were selected. Mononuclear inflammatory cells were analyzed. Histochemical and immunohistochemical analyses were performed using toluidine blue, anti-c-kit and anti-tryptase reagents, and the results were quantified in areas A and B of connective tissue. Mast cells of all OLP and OLLC samples were positive for toluidine blue, c-kit, and tryptase. The density of toluidine blue+, c-kit+ and tryptase+ mast cells was higher in tissue with OLP and OLLC compared with healthy controls (p < 0.05). No difference was noted in mast cells density between OLP and OLLC (p > 0.05). The density of tryptase+ mast cells was higher in the subepithelial region (area A) than the region below it (Area B) in OLLC (p = 0.047). The mononuclear inflammatory cell density was higher in OLLC compared to OLP, but without statistical significance (p > 0.05). A positive statistical correlation was found between mononuclear immune cells and density of c-kit+ and tryptase+ mast cells in OLP (r = 0.943 and r = 0.886, respectively). Our data demonstrate that the etiopathogenesis process of OLP and OLLC modulates the expansion and degranulation of mast cells; mast cells density, however, was similar between OLP and OLLC. The distribution of mast cells appears to vary along the lamina propria.

ABSTRACT OBJECTIVE To evaluate, using spatial analysis, the occurrence of American Cutaneous Leishmaniasis (ACL) and analyze its association with the municipal human development index (MHDI) and deforestation in the state of Amazonas, Brazil, from 2016 to 2020. METHODS This ecological study, carried out from January 2016 to December 2020, included the 62 municipalities of the state of Amazonas. The incidence rate of ACL was determined in space and time. Using Multiple Linear Regression by Ordinary Least Squares (OLS) and Spatial Autoregressive Regression (SAR) models, the relationship between incidence rates and Human Development Index (HDI) and deforestation was analyzed., The high- and low-risk clusters were identified by employing the Getis-Ord Gi* statistic. RESULTS A total of 7,499 cases of ACL were registered in all 62 municipalities in the state. Most cases were in male (n=5,924; 79.24%), with the greatest frequency in the population aged from 20 to 39 years (n=3,356; 44.7%). The incidence rate in the state of Amazonas was 7.34 cases per 100,000 inhabitants-year, with the municipalities of Rio Preto da Eva and Presidente Figueiredo showing the highest rates (1,377.5 and 817.5 cases per 100,000 population-year, respectively). The ACL cases were clustered into specific areas related to those municipalities with the highest incidence rates. The SAR model revealed a positive relationship between ACL and deforestation. CONCLUSIONS The occurrence of ACL was evident in a variety of patterns in the state of Amazonas; the high incidence rates and persistence of this disease in this state were linked to deforestation. The temporal distribution showed variations in the incidence rates during each year. Our results can help optimize the measures needed to prevent and control this disease in the state.

ABSTRACT Salinity is one of the abiotic stresses that affect gas exchange and growth of pomegranate. In this context, the application of nitrogen fertilizer through the leaves can minimize these effects. Thus, the objective of present study was to evaluate the effect of foliar nitrogen fertilization on pomegranate seedlings irrigated with brackish water. The design used was randomized blocks, in an incomplete factorial scheme (Central Composite Design) with five electrical conductivities of irrigation water - ECw (0.50, 1.15, 2.75, 4.35, and 5.00 dS m-1) and five doses of foliar nitrogen fertilization - FNF (0, 0.33, 1.15, 1.97, and 2.30 g L-1), with four replicates and two plants per experimental plot. Plant height, number of leaves, stem diameter, and gas exchange (stomatal conductance, net photosynthesis, intercellular CO2 concentration, transpiration rate, instantaneous carboxylation efficiency, instantaneous water use efficiency, and intrinsic water use efficiency) were evaluated at 60 days after the beginning of irrigation with saline water. Salinity of irrigation water negatively affects the gas exchange of pomegranate seedlings. Foliar nitrogen fertilization up to 1.31 g L-1 improves plant height and number of leaves in pomegranate seedlings under salt stress. Foliar nitrogen fertilization up to 1.59 g L-1 increases the net photosynthesis of pomegranate seedlings.

RESUMO A salinidade é um dos estresses abióticos que afeta as trocas gasosas e o crescimento de romãzeira. Neste sentido, à aplicação de adubo nitrogenado via foliar poderá minimizar estes efeitos. Com isso, o objetivo do presente estudo foi avaliar o efeito da aplicação foliar com nitrogênio em mudas de romã irrigadas com águas salobra. O delineamento utilizado foi de blocos casualizados, em esquema fatorial incompleto (Composto Central de Box), sendo cinco condutividade elétrica da água - CEa (0,50; 1,15; 2,75; 4,35 e 5,00 dS m-1) e cinco doses de adubação nitrogenada via foliar - ANF (0; 0,33; 1,15; 1,97 e 2,30 g L-1), com quatro repetições. A salinidade da água de irrigação afeta negativamente as trocas gasosas de mudas de romãzeira. A adubação nitrogenada foliar até 1,31 g L-1 melhora o crescimento em altura e no número de folhas em mudas de romãzeira sob estresse salino. Adubação nitrogenada foliar até a dose de 1,59 g L-1 aumenta a fotossíntese das mudas de romãzeira.

Abstract This paper analyzes the influence of government support on the implementation of video surveillance, one of the tools usable in smart cities, and the effect of this technology on the performance of public security in the city of Recife. With a qualitative approach, the study locus was the Integrated Center (CIODS), which encompasses the public security forces and provides the video monitoring service in Recife. Interviews were conducted with video surveillance operators. The results show that government support is essential; however, in Recife, it is understood as insufficient for the use of innovations in public security, especially concerning the technology analyzed here. It is concluded that integration between agencies in the video surveillance system favors the expansion and applicability of the concept of smart cities to Recife.

Resumo Este trabalho analisa a influência do apoio governamental na implementação da videovigilância, uma das ferramentas utilizáveis em cidades inteligentes, e o efeito desta no desempenho da segurança pública de Recife. De abordagem qualitativa, o locus foi o Centro Integrado (Ciods), que abarca as forças de segurança pública e oferta o serviço de videomonitoramento em Recife. A partir de entrevista com os operadores empregados na videovigilância, os resultados encontrados demonstram que o amparo governamental é essencial, porém, em Recife, ele é entendido como insuficiente ao emprego de inovações na segurança pública, em especial na tecnologia analisada. Ainda assim, conclui-se que a integração entre os órgãos no sistema de videovigilância favorece a expansão e a aplicabilidade do conceito de cidades inteligentes a Recife.

Abstract Background Detailed information about the electromyography practice in Brazil is largely unavailable. Objective To evaluate where and how electromyography is performed in Brazil, as well as regional disparities and the professional and academic credentials of electromyographers. Methods We conducted an internet-based survey of active Brazilian electromyographers. The websites of health insurance companies, professional academies, medical cooperatives, online search engines, and social networks in each Brazilian state were screened and we evaluated the credentials of each electromyographer listed in the Brazilian Federal Medical Board (BFMB) registration website and their online curricula vitae in the Brazilian National Council for Scientific and Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq, in Portuguese). We also evaluated the same parameters in a control group of non-electromyographer neurologists randomly matched by geographical distribution and gender. Results We found 469 electromyographers (384 neurologists and 85 non-neurologists), with a male predominance. In total, 81.9% were BFMB-certified neurologists, 49.9%, BFMB-certified clinical neurophysiologists, and 10.4%, BFMB-certified physiatrists. Among the non-neurologists, 48.2% were physiatrists. Most electromyographers practiced in states on the Southern and Southeastern regions of Brazil. When adjusted by population, the Federal District and the states of Mato Grosso do Sul and Goiás presented the highest of eletromyographers density. Electromyographers were not more likely to have current/past academic affiliations. Conclusion In Brazil, electromyography is performed predominantly by neurologists, and half of them are BFMB-certified clinical neurophysiologists. The present study highlights regional disparities and may guide government-based initiatives, for instance, to improve the diagnosis of leprosy and the management of neuromuscular disorders within the Brazilian territory.

Resumo Antecedentes Informações detalhadas sobre a prática de eletromiografia no Brasil são em grande parte indisponíveis. Objetivo Avaliar onde e como a eletromiografia é realizada no Brasil, as disparidades regionais, e as credenciais profissionais e acadêmicas dos eletromiografistas. Métodos Realizamos uma enquete via internet de eletromiografistas brasileiros ativos. Foram rastreados sites de operadoras de planos de saúde, academias profissionais médicas, cooperativas médicas, ferramentas de busca online e redes sociais em cada estado brasileiro. Em seguida, avaliamos as credenciais de cada eletromiografista listado no site de registro do Conselho Federal de Medicina (CFM) e seus curricula vitae online no Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Também avaliamos os mesmos parâmetros em um grupo controle de neurologistas não eletromiografistas pareados aleatoriamente por distribuição geográfica e gênero. Resultados Encontramos 469 eletromiografistas (384 neurologistas e 85 não neurologistas), com predominância do sexo masculino. Ao todo, 81,9% eram neurologistas com certificação confirmada pelo site do CFM, 49,9%, neurofisiologistas clínicos com certificação confirmada pelo site do CFM, e 10,4%, fisiatras com certificação confirmada pelo mesmo site. Entre os não neurologistas, 48,2% eram fisiatras. A maioria dos eletromiografistas atuava nos estados do Sul e do Sudeste. Quando ajustados pela população, o Distrito Federal e os estados de Mato Grosso do Sul e Goiás apresentaram a maior densidade de eletromiografistas. Os eletromiografistas não eram mais propensos a ter vínculos acadêmicos atuais/passados. Conclusão No Brasil, a eletromiografia é realizada predominantemente por neurologistas, e metade deles são neurofisiologistas clínicos com certificação confirmada pelo site do CFM. Este estudo destacou as disparidades regionais, e pode orientar ações governamentais para, por exemplo, melhorar o diagnóstico da hanseníase e o manejo das doenças neuromusculares no território brasileiro.

Resumo O artigo analisa a associação entre níveis de fadiga por compaixão e engajamento no trabalho com a COVID-19 em profissionais de enfermagem. Estudo longitudinal, tipo antes e depois, realizado com profissionais de enfermagem da linha de frente, nos períodos pré-pandêmico e pandêmico. Utilizou-se as versões brasileiras da Professional Quality of Life Scale e da Utrecht Work Engagement Scale. Observou-se altos níveis de satisfação por compaixão (≥43,0), baixos níveis de burnout (<23,0) e estresse traumático secundário (<23,0); e níveis altos de vigor (≥4,0 e ≤4,99), absorção (≥4,0 e ≤4,99) e escore geral (≥4,0 e ≤4,99). Houve correlação moderada, negativa e significativa do burnout com vigor (r: -0,505; p-valor: <0,001), no pré-pandemia; e com o escore geral, no pré-pandemia (r: -0,543; p-valor: <0,001) e período pandêmico (r: -0,458; p-valor: <0,001). Não houve alterações nos níveis de engajamento no trabalho. Profissionais com fadiga por compaixão tiveram redução do vigor, absorção e escore geral, classificados como médios no período pandêmico (≥2,0 e ≤3,99); e aumento da dedicação, que era baixa (≥1,0 e ≤1,99) no pré-pandemia. Concluiu-se não haver associação danosa entre fadiga por compaixão e engajamento no trabalho com a COVID-19 nos profissionais de enfermagem.

Abstract This article examines the association between levels of compassion fatigue and work engagement with COVID-19 in nursing professionals. A longitudinal, before-and-after study was conducted with nursing professionals working in the frontline in the pre-pandemic and pandemic periods. Our study applied the Brazilian versions of the Professional Quality of Life Scale and the Utrecht Work Engagement Scale. High levels of compassion satisfaction (≥43.0), low levels of burnout (<23.0) and secondary traumatic stress (<23.0), as well as high levels of vigor (≥4.0 and ≤4.99), absorption (≥4.0 and ≤4.99), and overall score (≥4.0 and ≤4.99) were observed. Moderate, negative, and significant correlations of burnout with vigor (r: -0.505; p-value: <0.001), in the pre-pandemic period; and with overall score, in the pre-pandemic (r: -0.543; p-value: <0.001) and pandemic periods (r: -0.458; p-value: <0.001), were also observed. No changes in levels of work engagement were found. Professionals with compassion fatigue showed decreased vigor, absorption, and overall score, rated as medium in the pandemic period (≥2.0 and ≤3.99), and an increased dedication, which was low (≥1.0 and ≤1.99) in the pre-pandemic period. It was concluded that there is no harmful association between compassion fatigue and work engagement with COVID-19 in nursing professionals.

ABSTRACT A great challenge of scientific research with carrot in semi-arid regions is obtaining the best productive characteristics and economic conditions by optimizing the green manure amounts using spontaneous species from the Caatinga biome, such as hairy woodrose (Merremia aegyptia L.) and roostertree (Calotropis procera Ait.). Therefore, this work aimed to agronomically and economically optimize the production of carrot roots in monocropping and of their components when fertilized with equitable biomass amounts of these spontaneous species in two cropping seasons in a semi-arid environment. The experimental design was a randomized complete block design, with five treatments and five replications. The treatments consisted of equitable amounts of hairy woodrose and roostertree biomass in amounts of 16, 29, 42, 55, and 68 t ha-1 on a dry basis. In each experiment, an additional carrot treatment without fertilizer (absolute control) was planted for comparison with the other treatments to determine maximum physical and economic efficiency. Carrot fertilization was performed with the incorporation of 48.87 t ha-1 of M. aegyptia and C. procera dry biomass into the soil to obtain the maximum optimized productive efficiency (commercial productivity). The maximum optimized agroeconomic efficiency (net income) of carrot cultivation was obtained when 49.64 t ha-1 of M. aegyptia and C. procera dry biomass was added to the soil. The use of biomass from these spontaneous species from the Caatinga biome as green manure is a viable technology for tuberose producers in monocropping in semiarid environments.

RESUMO Um grande desafio na pesquisa científica com cenoura em ambiente semiárido é obter as melhores características produtivas e condições econômicas otimizando as quantidades de adubos verdes de espécies espontâneas do bioma Caatinga, como a jitirana (Merremia aegyptia L.) e a flor-de-seda (Calotropis procera Ait.). Diante disso, esse trabalho teve como objetivo otimizar agronômica e economicamente a produção de raízes de cenoura em monocultivo e de seus componentes, quando adubados com quantidades equitativas de biomassa dessas espécies espontâneas, em duas estações de cultivos em ambiente semiárido. O delineamento experimental utilizado foi em blocos completos casualizados, com cinco tratamentos e cinco repetições. Os tratamentos consistiram de quantidades equitativas de biomassa de jitirana e de flor-de-seda nas doses de 16, 29, 42, 55 e 68 t ha-1 em base seca. Em cada experimento foi plantado um tratamento adicional com cenoura sem adubo (testemunha absoluta) para efeito de comparação com os demais tratamentos para determinar a máxima eficiência física ou econômica. A adubação da cenoura foi realizada com a incorporação de 48,87 t ha-1 de biomassa seca de M. aegyptia e C. procera ao solo para obtenção da máxima eficiência produtiva otimizada (produtividade comercial). A máxima eficiência agroeconômica otimizada (renda líquida) do cultivo da cenoura foi obtida quando 49,64 t ha-1 de biomassa seca de M. aegyptia e C. procera foram adicionados ao solo. A utilização da biomassa dessas espécies espontâneas do bioma Caatinga como adubação verde é uma tecnologia viável para produtores de tuberosas em monocultivo em ambientes semiáridos.

ABSTRACT The interest in the use of wastewater has grown, due to the limitation of good quality water, especially in the semi-arid region. The objective was to analyze the chemical alterations of soil irrigated with wastewater and phosphate fertilization, in the production of seedlings of Moringa oleifera Lam. The experiment was installed in a greenhouse, in the forest nursery of the Experimental Station Prof. Ignácio Salcedo from the National Institute of the Semi-Arid Region – INSA, Campina Grande – Paraíba. A randomized block design was adopted, factorial arrangement 5 x 2, with four replications, with five percentages of treated domestic wastewater, diluted in supply water (25%; 50%; 75%; 100% and treated supply water), associated with two nutritional factors (PA – phosphorus fertilization and SA – without fertilization). At 110 days after conducting the treatments, the following soil characteristics were evaluated: hydrogen potential, electrical conductivity, calcium, magnesium, sodium, phosphorus, potassium, sum of bases, aluminum, hydrogen, sulfate, cation exchange capacity and organic matter. The use of phosphate fertilizer contributed positively to the phosphorus, carbon, organic matter and cation exchange capacity of the soil. The increasing percentiles of wastewater leveraged the sum of bases and the cation exchange capacity, simultaneously promoted the increase in Na+, Al, H+Al contents and in the electrical conductivity of the soil saturation extract.

RESUMO O interesse na utilização de águas residuárias tem crescido, devido a limitação de água de boa qualidade, em destaque para o semiárido. Este trabalho teve por objetivo analisar as alterações químicas do solo irrigado com águas residuárias e da adubação fosfatada, na produção de muda de Moringa oleifera Lam. O experimento foi instalado em estufa, do viveiro florestal da Estação Experimental Prof. Ignácio Salcedo do Instituto Nacional do Semiárido – INSA, Campina Grande – Paraíba. Adotou-se o delineamento de blocos casualizados, arranjo fatorial 5 x 2, com quatro repetições, com cinco percentuais de água residual doméstica tratada, diluída em água de abastecimento (25%; 50%; 75%; 100% e água de abastecimento tratada), associados a dois fatores nutricionais (AF – adubação fosfatada e SA – sem adubação). Aos 110 dias após condução dos tratamentos, avaliaram-se as seguintes características do solo: potencial hidrogeniônico, condutividade elétrica, cálcio, magnésio, sódio, fósforo, potássio, soma de bases, alumínio, hidrogênio, sulfato, capacidade de troca catiônica e matéria orgânica. O uso da adubação fosfatada contribuiu de maneira positiva nos teores de fósforo, carbono, matéria orgânica e capacidade de troca catiônica do solo. Os percentis crescente de água residuária alavancaram a soma de bases e a capacidade de troca catiônica, simultaneamente promoveu o aumento nos teores de Na+, Al, H+Al e na condutividade elétrica do extrato de saturação do solo.

Abstract Discrepancies between Radiology reports and their subsequent patient outcomes are not necessarily considered error or malpractice. The Portuguese College of Radiology makes some pertinent considerations on these sensitive themes, intending to frame both European and North American concepts and visions for our national reality.

Resumo Discrepâncias entre relatórios dos exames da Radiologia e seus subsequentes desfechos nos pacientes não são necessariamente considerados erro ou má prática. O Colégio de Radiologia Português tece algumas considerações pertinentes sobre estas sensíveis temáticas pretendendo enquadrar conceitos e visões quer europeias quer norte-americanas para a nossa realidade nacional.

[Objective] Our main objective was to evaluate Favolus rugulosus indoor production in different substrates and to analyze the proximal composition of cultivated basidiomata. [Methodology] The studied species was identified by morphological and phylogenetic analyses based on ITS markers. Domestication capability was evaluated in different easy-access substrates. Total phenolic content and antioxidant activities were quantified, and proximal content was analyzed on cultivated basidiomata. [Results] Eucalypts sawdust-straw mixture produced basidiomata in higher yields in an intermediate amount of time (45 days). The highest concentration of phenolic compounds (35.6 ± 2.6 mg GAE g-1) and antioxidants (13.6 ± 1.3 mg AAE g-1) were obtained in the ethyl acetate fraction. Regarding proximal composition, F. rugulosus is composed of 20 % proteins, 15,4 % carbohydrates, 25,2 % dietary fiber and 5,7 % fat. [Conclusions] Nutritional composition analyses on cultivated basidiomata revealed F. rugulosus to be high in protein, carbohydrates, dietary fiber and essential fatty acids.

[Objetivo] El objetivo del trabajo fue evaluar la producción indoor de Favolus rugulosus en distintos sustratos y realizar los análisis de composición proximal de los basidiomas cultivados. [Metodología] La especie en estudio fue identificada por análisis morfológicos y filogenéticos basados en el marcador ITS. Se evaluó la capacidad de domesticación de la especie mediante el cultivo en distintos sustratos de fácil acceso, se cuantificó el contenido de compuestos fenólicos totales, antioxidantes y se realizó el análisis proximal de los basidiomas obtenidos. [Resultados] La mezcla eucalipto-paja resultó ser el mejor sustrato para la producción de basidiomas, por producir rindes más altos en un tiempo intermedio (45 días); la mayor concentración de compuestos fenólicos (35.6 ± 2.6 mg GAE g-1) y antioxidantes (13.6 ± 1.3 mg AAE g-1) se obtuvo en la fracción de acetato de etilo; en cuanto la composición proximal, F. rugulosus contiene 20 % proteínas, 15,4 % carbohidratos, 25,2 % fibra alimentaria y 5,7 % de grasas. [Conclusiones] Los análisis de composición química y nutricional del basidioma cultivado revelan que F. rugulosus es una fuente rica en&nbsp; proteínas, carbohidratos, fibra alimentaria y ácidos grasos esenciales.&nbsp;
