Resumen Contexto: La construcción en madera no está entre las opciones más populares debido a problemas culturales en Brasil. Los estándares y costos de la habitación en madera siguen siendo temas inciertos, y este estudio busca investigar estas brechas seculares. Método: Los costos unitarios básicos para diferentes estándares de acabado y tipos de producción se midieron a través de entrevistas cara a cara dirigidas por un cuestionario semiestructurado. Se utilizó un margen de error para validar todos los resultados. Se entrevistó aleatoriamente a empresarios de seis estados brasileños para obtener una muestra representativa. Resultados: El muestreo superó el 50% de la población del sector y proporcionó resultados significativos. Más del 40% de las técnicas de construcción en madera mostraron costos competitivos en comparación con la albañilería. Existen alternativas viables de vivienda en madera en los diferentes escenarios analizados. Conclusiones: Las casas de madera son económicamente viables en Brasil, incluso en comparación con los ejemplos tradicionales construidos en albañilería. Los costos atractivos para todas las clases sociales simbolizan un factor fuerte en la conquista de los mercados inmobiliarios.

Abstract Context: Timber construction is not among the most popular options due to cultural issues in Brazil. Timber housing standards and costs remain uncertain subjects, and this study seeks to investigate these secular gaps. Method: Basic unitary costs for different finishing standards and production types were measured through face-to-face interviews led by a semi-structured questionnaire. A margin of error was used to validate all results. Entrepreneurs from six Brazilian states were randomly interviewed to obtain a representative sample. Results: The sampling exceeded 50% of the sector population and provided significant outcomes. More than 40% of timber housing techniques showed competitive costs in comparison with masonry. There are feasible alternatives of timber housing for the different scenarios analyzed. Conclusions: Timber houses are economically viable in Brazil, even compared to traditional examples built via masonry. Attractive costs for all social classes symbolize a strong factor in conquering housing markets.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract: En | Text: En | PDF: En

Abstract Oral candidiasis is a common fungal infection that affects the oral mucosa, and happens when Candida albicans interacts with bacteria in the oral microbiota, such as Streptococcus mutans, causing severe early childhood caries. C. albicans and S. mutans mixed biofilms are challenging to treat with conventional antimicrobial therapies, thus, new anti-infective drugs are required. Objective This study aimed to test a drug delivery system based on chitosan microparticles loaded with geranium and lemongrass essential oils to inhibit C. albicans and S. mutans mixed biofilms. Methodology Chitosan microparticles loaded with essential oils (CM-EOs) were obtained by spray-drying. Susceptibility of planktonic were performed according CLSI at 4 to 2,048 µg/mL. Mixed biofilms were incubated at 37ºC for 48 h and exposed to CM-EOs at 256 to 4,096 µg/mL. The antimicrobial effect was evaluated using the MTT assay, with biofilm architectural changes analyzed by scanning electron microscopy. RAW 264.7 cell was used to evaluate compound cytotoxicity. Results CM-EOs had better planktonic activity against C. albicans than S. mutans. All samples reduced the metabolic activity of mixed C. albicans and S. mutans biofilms, with encapsulated oils showing better activity than raw chitosan or oils. The microparticles reduced the biofilm on the slides. The essential oils showed cytotoxic effects against RAW 264.7 cells, but encapsulation into chitosan microparticles decreased their toxicity. Conclusion This study demonstrates that chitosan loaded with essential oils may provide an alternative method for treating diseases caused by C. albicans and S. mutans mixed biofilm, such as dental caries.

RESUMO Os ensaios de progênies constituem estratégias de conservação genética ex situ e também de melhoramento genético, pois permitem selecionar genótipos de melhor qualidade e elevada produtividade. No entanto, o melhoramento genético florestal não tem sido devidamente aplicado para espécies nativas da região Amazônica. O objetivo deste trabalho foi investigar se progênies de Parkia multijuga possuem desempenho silvicultural diferenciado e se é possível agrupá-las em diferentes classes de desempenho. O experimento foi instalado no delineamento de blocos casualizados com 14 progênies, sendo, ao total,18 mudas por cada progênie plantadas em seis blocos (252 plantas). Três anos após o plantio foram avaliados os caracteres: diâmetro à altura do peito (DAP), altura total, altura do fuste, diâmetro da copa, comprimento da copa, área de copa, proporção de copa, grau de esbeltez (GE), índice de abrangência (IA), índice de saliência (IS), ocorrência de bifurcação, percentual de indivíduos com fuste retilíneo e o estado fitossanitário. Foram também calculados: a sobrevivência, o incremento médio anual em altura e diâmetro e o índice de resposta integrada (IRI = sobrevivência e incrementos). O IRI variou cerca de três vezes entre a melhor e a pior progênie, da qual as progênies 7, 6, 11 e 10 tiveram os maiores valores de IRI. Uma análise de componentes principais com as características silviculturais de maior interesse (IRI, DAP, GE, fuste retilíneo, bifurcação e estado fitossanitário) permitiu agrupar as progênies 6, 7 e 11 entre aquelas com melhor desempenho silvicultural. A maior parte das progênies apresentou desempenho intermediário e semelhante entre si, sendo o pior desempenho para a maioria das características relacionado à progênie 2. Progênies de Parkia multijuga divergem quanto ao desempenho silvicultural durante o estabelecimento inicial dos plantios. Logo, o agrupamento das progênies com melhores desempenhos é fundamental na seleção de materiais genéticos superiores para a composição de plantios de produção desta espécie na região Amazônica.

ABSTRACT Progeny tests are strategies for ex situ genetic conservation and genetic improvement, as they allow the selection of genotypes of better quality and high productivity. However, the tree genetic improvement has not been properly applied to native species of the Amazon region. We investigated if Parkia multijuga progenies have different silvicultural performance and if it is possible to cluster them into different performance classes. The experiment was settled in a complete random block design with 14 progenies, a total of 18 seedlings from each progeny planted in six blocks (252 plants). Three years after planting, the following variables were evaluated: diameter at breast height (DBH), total height, stem height, crown diameter, crown length, crown area, crown ratio, slenderness (S), range index (RI), salience index (SI), bifurcation occurrence, percentage of individuals with rectilinear stem and phytosanitary status. Survival, mean annual increment in height and diameter and the integrated response index (IRI = survival and increments) were also calculated. IRI varied about three times between the best and the worst progeny, of which the progenies 7, 6, 11 and 10 had the highest IRI values. The Principal Component Analysis of the most interesting silvicultural characteristics (IRI, DBH, GE, rectilinear stem, bifurcation, and phytosanitary status) allowed to group progenies 6, 7 and 11 among those with the best silvicultural performance. Most progenies showed intermediate and similar performance, being the worst performance for most traits related to the progeny 2. Progenies of Parkia multijuga diverge as to the silvicultural performance during the initial establishment of the plantations. Therefore, the grouping of progenies with better performance is fundamental in the selection of superior genetic material for the composition of productive plantations of this species in the Amazon region.

Este trabalho, de cunho quantitativo, objetivou avaliar o espaço que programas de pós-graduação stricto sensu brasileiros das áreas de engenharias dão à formação docente, que é um de seus objetivos, de acordo com a Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) e com a Lei 9.394/96 das Diretrizes e Bases da Educação (LDB). Tendo como base a análise da avaliação da pós-graduação entre 2013 e 2016, coletou-se mais de 1.600.000 dados extraídos da Plataforma Sucupira para identificar e quantificar a presença de termos chave da área de educação nos títulos de Disciplinas, Produções e Trabalhos Finais na área de engenharia. Observou-se que 0,39% das disciplinas, 0,8% da produção intelectual, 0,93% dos trabalhos finais e 0,54% da produção intelectual relevante dialogam de fato com a área pedagógica, concluindo que há uma desvalorização da formação docente nos programas analisados, reforçando estudos qualitativos prévios.

This quantitative paper aimed to evaluate the space allocated in brazilian post-graduate stricto sensu programs in engineering to teacher training, which is one of its objectives set by the brazilian law 9.394/96, of the Guidelines and Bases of Education (LDB), and the agency Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES, Coordination for the Improvement of Higher Education Personnel). Based on data analysis of the postgraduate evaluation between 2013 and 2016, more than 1,600,000 data were extracted from the Sucupira platform to identify and quantify the presence of key terms of education in the Subject titles, Intellectual Production and Major/Minor works in engineering. It was observed that 0.39% of the subjects, 0.8% of the intelectual production, 0.93% of the final papers and 0.54% of the relevant intellectual production actually work with the pedagogical area, concluding that there is a devaluation of the teaching training in the analyzed programs, reinforcing previous stud.

RESUMO Para identificar o tempo gasto com as diferentes técnicas de construção de casas de madeira, este estudo avalia o tempo de execução de diferentes modelos disponíveis no Brasil. Utilizando entrevistas face-a-face, formulários semiestruturados foram randomicamente aplicados para coletar o tempo médio de acordo com distintos métodos de produção. As técnicas mais eficientes foram: ‘tábua e mata-junta’, ‘pilar-viga’ e ‘casa de toras ’ utilizando produção artesanal; ‘tábua e mata-junta’, ‘paliteiro com alvenaria’ e ‘pilar-viga’ em processo semi-industrial; e, ‘modular para canteiros de obras ’, ‘modular em madeira laminada colada-cruzada’ e ‘entramado leve modular’ em produção industrial. Diferentes produtores industriais não foram tão ágeis como seus concorrentes artesanais devido aos obstáculos produtivos em projetos customizados. A construção em madeira oferece um tempo produtivo mais baixo que a alvenaria, representando uma forma ágil para construir uma moradia sustentável e versátil.

ABSTRACT To identify the time spent with the different construction techniques of timber houses, this study evaluates the execution time of different models available in Brazil. Using face-to-face interviews, semi-structured questionnaires were randomly applied to collect average time according to distinct production methods. The most efficient techniques were: ‘clapboard and wainscot’, ‘post-and-beam’, and ‘log-home’ using artisanal production; ‘clapboard and wainscot’, ‘stick framing with masonry’, and ‘post-and-beam’ in semi-industrial process; and, ‘modular for building sites’, ‘modular in cross-laminated timber’ and ‘modular woodframe’ in industrial production. Different industrial developers were not as agile as artisanal competitors due to production obstacles in customized projects. Timber construction offers lower execution time than masonry, representing an agile form to build a versatile sustainable dwelling.

ABSTRACT Species of the genus Mansonia Blanchard are disease pathogen vectors in some regions of the world and can cause considerable inconvenience due to their bites when present in high numbers. However, little is known regarding their biology in Brazil. The objective of this work was to investigate some reproductive parameters of Mansonia from the western Brazilian Amazon. Females were captured in the field using human landing catches in rural areas of Porto Velho, Rondonia, Brazil. The mosquitoes were identified and separated into two groups for oviposition: forced, i.e., with wing removal, and free oviposition, without wing removal. Daily observations of oviposition and female survival were conducted until oviposition. The eggs and subsequent larvae were counted for fecundity and fertility evaluation, respectively. The species collected in this study were Mansonia amazonensis (Theobald), Mansonia humeralis Dyar & Knab and Mansonia titillans (Walker). The oviposition percentage for Ma. amazonensis was much lower than for Ma. humeralis and Ma. titillans. Forced oviposition resulted in a higher number of ovipositing females only for Ma. humeralis. Fecundity and fertility were not affected by the oviposition method. Egg and larval numbers were generally lower for Ma. amazonensis compared with the other species. Forced oviposition may be a tool to increase the number of ovipositing females depending on the Mansonia species studied in order to establish colonies in the laboratory.

Abstract This study aims to assess the psychometric properties of the instrument Modified Checklist for Autism in Toddlers (M-CHAT) in children from 24 to 36 months old with (Group 1/n = 88) and without (Group 2/n = 1116) Autism Spectrum Disorder (ASD). Internal consistency was evaluated and sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were estimated. Also, the Receiver Operating Characteristic (ROC) curve was generated. To evaluate the discriminant validity, the proportion of flaws among children with and without ASD was assessed by applying the Chi-square test or by the Exact Fisher test. The number of flaws based on sex, age group, and participant’s group was also compared with the Mann-Whitney Test. The M-CHAT showed high internal consistency (0.78 and 0.86), satisfactory reproductivity (Kappa 0.60 and 0.79 and ICC = 0.87 and 0.89), high sensibility (0.807 and 0.932), specificity (0.927 and 0.706), and NPV (0.984 and 0.992); however, PPV estimates (0.467 and 0.250) were not satisfactory. Regarding the discriminant validity, the proportion of flaws was significantly higher in the group of children with ASD. Moreover, the number of flaws was larger among boys, in the age group 25-36 months, and in the group with ASD. The Brazilian version of M-CHAT has adequate psychometric properties concerning reliability, sensitivity, specificity, NPV and discriminant validity, which makes its application recommendable to track children with ASD signs.

Resumen Ese estudio tuvo como objetivo evaluar las propiedades psicométricas del Modified Checklist for Autism in Toddlers (M-CHAT) en niños de 24 a los 36 meses de edad con (grupo 1/n=88) y sin (grupo 2/n=1116) el trastorno del espectro autista (TEA). Fueron evaluadas la consistencia interna y estimadas la sensibilidad, especificidad, valor predictivo positivo (VPP), valor predictivo negativo (VPN). Además, se construyó la curva Receiver Operating Characteristic (ROC). Para evaluar la validad discriminante se comparó la proporción de los fracasos entre los niños con y sin TEA, utilizando el examen chi-cuadrado o la prueba exacta de Fisher. Se compararon también el número de fracasos según el sexo, edad y grupo de participantes por medio del teste Mann-Whitney. El M-CHAT presentó consistencia interna elevada (0,78 y 0,86), reproductividad satisfactoria (Kappa de 0,60 a 0,79 e CCI = 0,87 e 0,89), alta sensibilidad (0,807 e 0,932), especificidad (0,927 e 0,706) y VPN (0,984 e 0,992), pero las estimativas del VPP (0,467 e 0,250) no fueron satisfactorias. Acerca de la validad discriminante, se observó que la proporción de fallas fue significativamente mayor en el grupo de niños con TEA. El número de fracasos fue mayor entre los niños varones, de 25 a 36 meses de edad y no en el grupo con TEA. La versión brasileña del M-CHAT tiene propiedades psicométricas adecuadas en lo que concierne a la confiabilidad, sensibilidad, especificidad, VPN y validad discriminante, lo que hace que su aplicación sea recomendada para rastrear los niños con señales de TEA.

Resumo O objetivo deste estudo foi avaliar as propriedades psicométricas do Modified Checklist for Autism in Toddlers (M-Chat) em crianças de 24 a 36 meses de idade com (Grupo 1/n = 88) e sem (Grupo 2/n = 1116) o transtorno do espectro do autismo (TEA). Avaliou-se a consistência interna e estimou-se a sensibilidade, especificidade, valor preditivo positivo (VPP), valor preditivo negativo (VPN). Além disso, construiu-se a curva Receiver Operating Characteristic (ROC). Para avaliar a validade discriminante, comparou-se a proporção de falhas entre as crianças com e sem o TEA, utilizando o teste qui-quadrado ou teste Exato de Fisher. Comparou-se ainda o número de falhas segundo sexo, faixa etária e grupo do participante por meio do teste de Mann-Whitney. O M-Chat apresentou consistência interna elevada (0,78 e 0,86), reprodutibilidade satisfatória (Kappa de 0,6 a 0,79 e CCI = 0,87 e 0,89), alta sensibilidade (0,807 e 0,932), especificidade (0,927 e 0,706) e VPN (0,984 e 0,992), porém as estimativas do VPP (0,467 e 0,250) não foram satisfatórias. Quanto à validade discriminante, observou-se que a proporção de falhas foi significativamente maior no grupo de crianças com TEA. Observou-se também que o número de falhas foi maior entre as crianças do sexo masculino, com faixa etária de 25-36 meses e no grupo com TEA. A versão brasileira do M-Chat tem propriedades psicométricas adequadas no que se refere à confiabilidade, sensibilidade, especificidade, VPN e validade discriminante, o que torna recomendável sua aplicação para rastrear crianças com sinais do TEA.

Resumo A importância da construção civil se relaciona com o desenvolvimento dos territórios, permeando gerações. Mas, pouco se sabe acerca dos setores produtivos da construção civil, sobretudo, do ramo direcionado às casas de madeira. Assim, este estudo identificou e caracterizou os polos empresariais brasileiros das casas de madeira, cujos fins foram relacionados ao autoconhecimento qualitativo-quantitativo-geográfico por parte de atores e potenciais parceiros desse setor. Duas fases foram conduzidas no estudo, sendo a análise das empresas efetivamente ativas para identificar as suas concentrações e o mapeamento dos polos empresariais a partir da proposta de uma escala hierárquica. A prospecção de dados foi suportada por buscas em websites e redes sociais das empresas. Os achados evidenciaram um dinamismo setorial em tempos de retração, já que o volume de empresas ativas tem crescido em comparação aos raros estudos. A maioria das empresas está ativa e apresenta atividades mais focadas à produção do que ao comércio. As concentrações e os polos empresariais se intensificaram na direção Norte-Sul do país, especificamente, nas áreas metropolitanas desenvolvidas e regiões costeiras.

Abstract The importance of civil construction is related to development of territories, permeating generations. But, little is known about civil construction production sectors, especially, in the group directed to timbered houses. Thus, this study identified and characterized those Brazilian poles of timber houses, whose purposes were related to the qualitative-quantitative-geographical self-knowledge by actors and business partners of this sector. Two phases were carried out in the study, being the analysis of companies effectively active to identify their concentrations, and the mapping of business poles from the proposal of a hierarchical scale. Data prospection was supported by the searching of company websites and social networks. Findings evinced a sectoral dynamism in times of retraction, since the volume of active companies has grown in comparison to the rare studies. Most companies are active and present activities more focused on production than market. Business concentrations and poles intensified in the North-South direction of the country, specifically, in developed metropolitan areas and coastal regions.

Abstract The coronavirus disease 2019 (COVID-19) outbreak has created unprecedent challenges for healthcare systems worldwide. Oncology services have been reorganized to decrease the risk of nosocomial acquisition of SARS-CoV-2, but changes in treatment pathways and follow-up cancer care can result in patients receiving suboptimal or delayed care. Herein, we describe a cross-sectional nested cohort study conducted to evaluate delays in care for patients with head and neck cancer (HNC) in post-treatment follow-up or palliative care during the COVID-19 pandemic in Northeast Brazil and its impact on health outcomes. Information was extracted from medical records and supplemented by telephone interviews. We compared the following health outcomes: self-perception of anxiety or sadness, fear of COVID-19 infection, cancer-related complications during social isolation, self-medication, diagnosis of COVID-19, and death between patients with and without delayed cancer care. The Mann-Whitney U test was used to compare distributions of continuous variables and the Fisher exact test was used for categorical variables. Thirty-one HNC patients were included in the study, and no case of confirmed SARS-CoV-2 was found. Delayed cancer care due to restriction in health services was reported in 58.1% of cases, and there was no report of telemedicine use during the COVID-19 outbreak. Cancer-related complications during the COVID-19 pandemic were described for most patients (67.7%) and included pain or discomfort, swelling, and dyspnea. Eight (25.8%) patients reported use of prescribed morphine or codeine to manage pain and six (19.4%) patients reported self-medication with over-the-counter (OTC) non-steroidal anti-inflammatory drugs (NSAIDs). We found an association between delayed HNC care and the use of self-medication (p = 0.028). This study indicated that patients with delayed HNC care during the COVID-19 outbreak are more likely to use self-medication with NSAIDs for pain management. Better strategies to follow HNC patients in socioeconomically disadvantaged communities need to be discussed and implemented.

Resumo Maturação interfere em aspectos fisiológicos e mecânicos da contração muscular. O objetivo do estudo foi comparar a eficiência do ciclo alongamento-encurtamento (SSC) em diferentes estágios maturacionais. Cento e quarenta e seis jovens, sendo 72 meninos e 74 meninas, foram recrutados para participar do estudo. Maturação sexual foi mensurada e o grupo foi estratificado em adolescentes (≥ 3 e crianças (< estágio 2). Salto estático (SJ) e o salto contramovimento (CMJ) foram utilizados para mensurar a força reativa (RF), razão de utilização da excêntrica (EUR) e aumento do pré-estiramento (PSAP). As crianças não apresentaram diferença significante entre SJ e CMJ (t(55)= -1.93; ∆ = -0.61; 95% CI = -1.24 to -0.02; p = 0.058), Enquanto que os adolescentes apresentaram maior desempenho de CMJ (t(89)= -12.28; ∆ = -2.44; 95% CI = -2.84 to -2.05; p <0.001). Em adição, adolescentes apresentaram maior RF (t(144)= 5.18; p <0.0001; 95% CI = 2.53 to 1.13), PSAP (t(144)= 4.38; p <0.0001; 95% CI = 14.00 to 5.29) e EUR (t(144)= 4.38; p <0.0001; 95% CI = 0.14 to 0.05). Nós concluímos que jovens com mais maturados apresentam maior capacidade de utilização do SSC.

Abstract Maturation interferes with physiological and mechanical aspects of muscle contraction. The aim of the present study was to compare the efficiency of the stretch-shortening cycle (SSC) between different maturation stages. One hundred forty six young people, with 72 boys and 74 girls, were recruited to participate in the study. Sexual maturation was measured and the group was stratified into adolescents (> 3 auto-tanner) and children (<2 auto-tanner). Squat jump (SJ) and countermovement jump (CMJ) performance were measured to measure reactive force (RF) capacity, eccentric utilization ratio (EUR) and pre-stretch augmentation (PSAP). The children did not present statistical difference between SJ and CMJ (t(55)= -1.93; ∆ = -0.61; 95% CI = -1.24 to -0.02; p = 0.058), while the adolescents presented higher performance of CMJ (t(89)= -12.28; ∆ = -2.44; 95% CI = -2.84 to -2.05; p <0.001). In addition, adolescents had higher RF performance (t(144)= 5.18; p <0.0001; 95% CI = 2.53 to 1.13), PSAP (t(144)= 4.38; p <0.0001; 95% CI = 14.00 to 5.29) and EUR (t(144)= 4.38; p <0.0001; 95% CI = 0.14 to 0.05). We conclude that more mature young people have better SSC utilization.
