RESUMO Os grãos imaturos de feijão-caupi são uma rica fonte de proteínas, minerais, fibra alimentar e compostos fenólicos e também possuem alta capacidade antioxidante em comparação aos grãos secos. O seu consumo promove uma alimentação saudável e diversificada. O objetivo deste trabalho foi avaliar o tempo de cozimento e a composição química e mineral de grãos imaturos crus e cozidos de diferentes genótipos de feijão-caupi. Foram analisados quatro genótipos, duas linhagens elite (MNC00-595F-27 e MNC05847B-123) e duas cultivares comerciais (BRS-Tumucumaque e Vagem Roxa-THE). O tempo de cozimento foi avaliado utilizando-se o cozedor de Mattson. Foram determinados a composição centesimal e minerais. Adotou-se o delineamento inteiramente casualizado com três repetições em esquema fatorial 1 (genótipo) × 2 (grãos crus e cozidos), exceto para qualidade de cozimento. Os genótipos MNC05847B-123 e BRS-Tumucumaque diferiram dos demais genótipos, apresentando cozimento mais rápido do grão imaturo. O cozimento aumentou o teor de umidade e reduziu o teor de cinzas, lipídios, proteínas e carboidratos e o valor energético total. As linhagens MNC05-847B-123 e MNC00-595F-27 apresentaram teores de nutrientes da composição centesimal mais altos após o cozimento que a cultivar local Vagem Roxa-THE, exceto para o teor de umidade. O teor de minerais diminuiu após o cozimento, sendo que os teores de Fe, Zn e Mn tiveram as menores perdas com o processamento térmico. As linhagens MNC05-847B-123 e MNC00595F-27, mesmo com perdas após o processamento térmico do grão imaturo, apresentam potencial nutricional como cultivares para o mercado de feijão verde. feijãocaupi caupi secos diversificada feijãocaupi. caupi.

ABSTRACT Immature cowpea grains are a rich source of proteins, minerals, dietary fiber, and phenolic compounds and also have a high antioxidant capacity compared to dry grains. Its consumption promotes a healthy and diversified diet. The objective of this work was to evaluate the cooking time and chemical and mineral composition of the raw and cooked immature grains of different cowpea genotypes. Four genotypes, two elite lines (MNC00-595F-27 and MNC05-847B-123) and two commercial cultivars (BRSTumucumaque and Vagem Roxa-THE) were analyzed. Cooking time was evaluated using the Mattson cooker. Proximate composition and minerals were determined. A completely randomized design with three replications in factorial scheme 1 (genotype) × 2 (raw and cooked grains) was adopted, except for cooking quality. The genotypes MNC05-847B-123 and BRS-Tumucumaque differed from the other genotypes, presenting faster cooking of the immature grain. Cooking increased the moisture content and reduced ash, lipid, protein, and carbohydrates contents and total energy value. The lines MNC05-847B-123 and MNC00-595F-27 showed higher contents of the nutrients of the centesimal composition after cooking than the local cultivar Vagem Roxa-THE, except for the moisture content. The mineral content decreased after cooking, with Fe, Zn, and Mn contents having the least losses with thermal processing. The lines MNC05-847B-123 and MNC00-595F-27, even with losses after the thermal processing of the immature grain, have nutritional potential as cultivars for the green-bean market. proteins fiber diet MNC00595F27 MNCF MNC00 595F 27 MNC F (MNC00-595F-2 MNC05847B123 MNCB MNC05 847B 123 B BRSTumucumaque RoxaTHE Roxa THE Roxa-THE analyzed cooker determined genotype (genotype adopted quality MNC05-847B-12 BRS Tumucumaque grain ash lipid protein value MNC00-595F-2 RoxaTHE, THE, Fe Zn MNC00595F27, 27, greenbean green bean market MNC00595F2 MNC0 (MNC00-595F- MNC05847B12 12 MNC05-847B-1 MNC00-595F- MNC00595F (MNC00-595F MNC05847B1 MNC05-847B- MNC00-595F MNC05847B MNC05-847B

Abstract Objectives: To answer the question: Can sterilized pouches be used a second time while maintaining their sterility conditions? Methods: This investigation tested paper/plastic sterilization pouches divided into three groups: experimental group - twice-used pouches; negative control group - once-used pouches; and positive control group - environmentally contaminated pouches. In the experimental group, pouches were opened, a gauze dressing was placed into them, and they were sterilized again, representing the reuse of the pouches (second sterilization cycle). After the sterilization cycle, samples were stored for 1 day (T0), 7 days (T1), 31 days (T2), and 153 days (T3). Positive control group pouches were opened and exposed to contamination in the storage environment. After the specified storage period, the experimental and negative control groups’ pouches were opened, and the gauze dressings were removed aseptically. All gauze dressings of all groups, including the positive control group, were incubated in Petri dishes with nutrient agar at 37°C for 3 days. After incubation, the Petri dishes were inspected, and the microbial contamination was assessed and classified as present or absent. Results: The experimental group’s Petri dishes showed no sign of contamination. The same happened to the negative control group. The positive control group’s Petri dishes presented microbial contamination. The same results were obtained for all incubation times. Conclusions: This study showed that sterilization pouches could be used a second time while maintaining sterility and integrity conditions, even for extended periods (153 days - 5 months of storage).

Resumo Objetivos: Este estudo tinha como objetivo testar se as mangas de esterilização poderiam ser utilizadas uma segunda vez mantendo as suas condições de esterilização. Métodos: Amostras de mangas de esterilização de papel/plástico foram testadas neste trabalho sendo divididas em 3 grupos (grupo experimental - mangas reutilizadas duas vezes; grupo de controlo negativo - mangas usadas uma vez; e um grupo de controlo positivo - amostras ambientalmente contaminadas). O grupo experimental incluiu mangas que foram abertas e uma foi gaze introduzida, sendo novamente fechadas e esterilizadas, representando assim a reutilização das mangas. Após o ciclo de esterilização, todas as amostras foram armazenadas durante 1 dia (T0), 7 dias (T1), 31 dias (T2) e 153 dias (T3). Quanto às amostras do grupo de controlo positivo, após o ciclo de esterilização, estas foram abertas e expostas à contaminação presente no ambiente de armazenamento. Após cada ciclo de armazenamento, as gazes foram incubadas em placas de Petri com Agar Nutriente a 37°C durante 3 dias. Após o período de incubação, as placas de Petri foram inspecionadas e a contaminação microbiana foi verificada e classificada como presente ou ausente. Resultados: A observação das placas de Petri do grupo experimental não mostrou sinais de contaminação. O mesmo aconteceu com o grupo de controlo negativo. As restantes placas de Petri contendo os controlos positivos apresentaram contaminação microbiana. Os mesmos resultados foram obtidos para todos os períodos de incubação. Conclusões: Este estudo mostra que as mangas de esterilização podem ser utilizadas uma segunda vez, mantendo as suas condições de esterilidade e integridade mesmo para longos períodos de tempo (153 dias - 5 meses de armazenamento).

Abstract Numerous Antarctic species are recognized as reservoirs for various pathogens, and their migratory behavior allows them to reach the Brazilian coast, potentially contributing to the emergence and circulation of new infectious diseases. To address the potential zoonotic risks, we conducted surveillance of influenza A virus (IAV) and coronaviruses (CoVs) in the Antarctic Peninsula, specifically focusing on different bird and mammal species in the region. During the summer of 2021/2022, as part of the Brazilian Antarctic Expedition, we collected and examined a total of 315 fecal samples to target these respiratory viruses. Although we did not detect the viruses of interest during this particular expedition, previous research conducted by our team has shown the presence of the H11N2 subtype of influenza A virus in penguin fecal samples from the same region. Given the continuous emergence of new viral strains worldwide, it is crucial to maintain active surveillance in the area, contributing to strengthening integrated One Health surveillance efforts. pathogens coast diseases risks IAV (IAV CoVs (CoVs Peninsula region 20212022 2021 2022 2021/2022 Expedition 31 expedition HN H N H11N worldwide area efforts 2021202 202 2021/202 3 202120 20 2021/20 20212 2 2021/2 2021/

Abstract This study aimed to evaluate the influence of the addition of coconut (coir) fibers on the microstructural, hydraulic and mechanical behavior of an unsaturated compacted soil. Specimens were molded and compacted, forming composites with 0%, 0.1%, 0.5% and 1% fiber in relation to their dry mass. The characterization of pores from the soil and fiber soil mixtures was performed by the Mercury Intrusion Porosimetry tests. Suction values were obtained through the filter paper method and soil water retention curves were adjusted with the Durner model due to the bimodal behavior. Tensile strength values were obtained from the indirect tensile strength test (Brazilian tensile test) for specimens with different suction values. It was found that the increase in fiber content in the material lead to a non-linear increase in macropores, which affected both the hydraulic and mechanical behavior of the soil. Furthermore, the shape of the soil water retention curve was preserved, but there were changes in the values of first and second air entry and residual suction. The tensile strength was negatively influenced, reaching a reduction of about 30% in the situation with higher fiber content. However, for higher levels, the behavior of the soil changed from brittle to ductile, increasing the supported deformations. coir (coir microstructural 0 0% 01 1 0.1% 05 5 0.5 mass tests Brazilian nonlinear non linear macropores Furthermore preserved influenced 30 However levels ductile deformations 0.1 0. 3

This work aims to evaluate the recycling of firewood ash waste as a procedure to provide sustainable raw material for ceramic floor tiles with low water absorption. For this purpose, firewood ash waste coming from a red ceramic company in Campos dos Goytacazes-RJ (Brazil) was selected as an alternative raw material into a ceramic floor tile body, replacing natural quartz material by up to 10 wt.%. Floor tile pieces containing up to 10 wt.% of firewood ash waste were prepared by the dry process, pressed, and fired between 1190 ºC and 1250 ºC using a fast-firing cycle. The floor tile pieces were tested to determine their properties (linear shrinkage, water absorption, apparent porosity, apparent density, and flexural strength). The results showed that the partial replacement of quartz with firewood ash waste, in the range up to 10 wt.%, allows the production of ceramic floor tiles with low water absorption (WA) (BIa group - WA < 0.5% and BIb group - 0.5 < WA ≤ 3%; ABNT NBR ISO 13006:2020 Standard) in different amounts of firewood ash waste at lower firing temperatures. purpose GoytacazesRJ Goytacazes RJ Brazil (Brazil body 1 wt wt. process pressed 119 125 fastfiring fast cycle linear shrinkage porosity density strength. strength . strength) (WA BIa 05 0 5 0. 3% 3 130062020 13006 2020 13006:202 Standard temperatures 11 12 13006202 1300 202 13006:20 1300620 130 20 13006:2 130062 13 2 13006:

Abstract The objective of this study was to evaluate the drying system using a dryer with furnace automatically fed with eucalyptus chips and another dryer manually fed with eucalyptus firewood, as well as assessing the quality of corn grains. Harvest was mechanically performed and the grains were transported by trucks to the storage unit for drying. Corn grain drying was conducted in mixed-flow dryers with a nominal capacity of 100 tons per hour. For air heating, two direct-fired furnaces were used, one automatically fed with eucalyptus chips and the other manually fed with firewood. Corn grains were evaluated for moisture content, apparent specific mass, thousand-grain weight, polycyclic aromatic hydrocarbons (PAHs), electrical conductivity and color. Drying corn grains with direct fire using firewood or chips as fuel causes contamination by PAHs. In general, the use of firewood or chips did not influence the quality of thousand-grain weight, apparent specific mass and color, while the use of chips increased electrical conductivity. It is essential that research advances in this subject, prioritizing the contamination of food, with proven carcinogenic activity, which should be treated as a high risk to public health.

RESUMO Crianças e adolescentes com deficiência física apresentam desafios motores e socioemocionais que interferem na qualidade de vida relacionada à saúde e os colocam em maior risco de desenvolver doenças secundárias. Além disso, estão mais sujeitos a restrições de serviços adequados que ofereçam terapias, principalmente para a população de baixa renda social. Torna-se necessário oferecer ações voltadas para a promoção da saúde em um sentido mais amplo, oferecendo não só meios de habilitação e reabilitação física, mas também de ganhos sociais e emocionais. Este objetivo pode ser atingido com esportes adaptados e atividades recreativas nos quais o condicionamento físico é acompanhado por ganhos em autoestima e benefícios sociais. Com a pandemia de COVID-19 e o isolamento social, crianças e adolescentes com deficiência física ficaram ainda mais privados de assistência. Relatamos aqui o esforço de uma organização não-governamental esportiva em manter o atendimento físico e psicológico por meio de consultas virtuais, e avaliamos as percepções das partes interessadas no processo. Nível de evidência IV; série de casos .

ABSTRACT Children and adolescents with physical disabilities have motor and social-emotional challenges that interfere with their health-related quality of life and put them at greater risk of developing secondary conditions. Moreover, services that provide them therapies are more likely to be restricted, especially for the low-income population. There must be broader actions towards health promotion, offering not only means for physical habilitation and rehabilitation but for social and emotional improvements as well. This goal is attainable by adaptive sports and recreational activities where physical conditioning is accompanied by an improvement in self-esteem and social benefits. With the COVID-19 pandemic and social isolation, children and adolescents with physical disabilities were even further deprived of assistance. Our aim was to report the efforts of a non-governmental sports organization in maintaining physical and psychological care through virtual consultations and to analyze the perceptions of those affected by the process.

Abstract The objective of this work was to evaluate the drying performance, the quality of the corn grain and the contamination by polycyclic aromatic hydrocarbons (PAHs) using a direct-fired furnace fed automatically by wood chips. Samples were collected at five-minute intervals, 12 samples before drying and 12 samples after drying. The following experimental evaluations were carried out: dryer – performance and fuel consumption; grains – moisture content, germination, electrical conductivity, apparent specific mass, mass of a thousand grains, color and PAHs. The dryer showed an average efficiency of 83.61%. The average consumption of wood chips was 0.3932 kg of chips per kilogram of evaporated water. Differences were observed in the grains after drying for the characteristics of mass of a thousand grains, apparent specific mass, germination and electrical conductivity. The average concentrations of PAHs in corn grains were higher than the maximum values allowed by the European Union legislation.

Abstract Objective To find evidence of the content, construct, and criterion validity of the LABIRINTO scale for the diagnosis of autism spectrum disorder (ASD) in children aged 24-59 months. Methods The scale was constructed in four stages: 1) items were defined based on an extensive literature review and discussions with autism and child development specialists; 2) child development specialists evaluated each item; 3) a preliminary version of the scale was applied to children diagnosed with ASD to enable any necessary adjustments; 4) the scale was then applied to 27 children with typical development and no neurodevelopmental disorder and 48 children with ASD. According to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the Childhood Autism Rating Scale (CARS), clinical diagnosis constitutes the gold standard. Results The scale’s psychometric indexes were appropriate for construct validity, with Kaiser-Meyer-Olkin = 0.94 and root mean square error of approximation = 0.000. Only one factor on the scale had a Cronbach alpha of 0.97. The receiver operating characteristic curve indicated a cutoff of 12, with a sensitivity of 100% and specificity of 100% for distinguishing children with ASD from those with typical development. Conclusion This study confirmed the validity of the LABIRINTO scale.

Resumo A literatura aponta para a existência de fragilidades na rede de atenção psicossocial, sobretudo, no tratamento de crianças e de adolescentes usuários de drogas. Este estudo teve como objetivo compreender, a partir do referencial teórico winnicottiano, como uma Unidade de Acolhimento infantojuvenil vem oferecendo cuidado a crianças e a adolescentes com necessidades decorrentes do uso de drogas e em situação de vulnerabilidade social. Foram realizadas entrevistas semiestruturadas com oito profissionais e 65 horas de observação participante. A partir da análise temática foram construídos três temas: (1)Ambiente: sobre atenção às necessidades básicas e construção de rotina; (2) Olhar: sobre empatia e ampliação de perspectivas; (3) Agressividade: sobre novas formas de se relacionar. São discutidas ações que visam à construção do cuidado para essa população específica já que essa é uma temática atual com políticas públicas recentes e fragilmente estruturadas.

Abstract The literature highlights the existence of weaknesses in the psychosocial care network, especially in the treatment of children and adolescents that use drugs. The study aimed to comprehend, based on the Winnicottian theoretical framework, how a Residential Care Unit has been providing care to children and adolescents with needs arising from drugs use in situations of social vulnerability. Semi-structured interviews, with eight care providers, and 65 hours of participant observation were carried out. From the thematic analysis, three themes were constructed: (1) Setting: regarding attention to basic needs and construction of a routine; (2) View: regarding empathy and expansion of perspectives; (3) Aggressiveness: regarding new ways of relating. Important actions are aimed at constructing care for this specific population, as this is a current theme with recent and weakly structured public policies.

Resumo O timo ectópico é uma anormalidade embriológica bem conhecida em crianças, apesar de ser considerado raro. Para evitar biópsias desnecessárias, os radiologistas devem estar cientes dessa condição, principalmente na população pediátrica. Este artigo descreve um paciente pediátrico com história de episódios recorrentes de amigdalite desde os 2 anos de idade. No contexto de uma mononucleose infeciosa foi realizada uma ecografia cervical, que revelou uma lesão relativamente hipoecóica no lobo direito da glândula tireóidea, semelhante à ecogenicidade normal do timo. Os testes de função tireóidea foram normais. Após 3 anos de acompanhamento, o nódulo intratiroideu mantém as características iniciais e diminuiu de tamanho de 12 mm para 8 mm.

Abstract Ectopic thymus is a well-known embryological abnormality in children, despite being considered rare. To avoid unnecessary examination or biopsy, radiologists must be aware of this condition, especially in pediatric population. This report describes a pediatric patient with history of recurrent episodes of tonsillitis since 2 years of age. In the context of infectious mononucleosis, a cervical ultrasound was performed, which revealed a relatively hypoechoic lesion in the right lobe of the thyroid gland, similar to normal thymus echogenicity. Thyroid function tests were normal. After 3 years of follow-up, the intrathyroidal nodule maintained the same characteristics, having decreased in size from 12 mm to 8 mm.

Abstract Although the conservation of tropical biodiversity depends on protected areas, there is still a very large ‘gap’ of knowledge on the flora of Brazilian reserves, especially in the Northeast region of Brazil. Field and herbarium surveys of the phanerogamic flora of the Ubajara National Park, located on the Brazilian Northeast, were made and analyses on phenology and dispersal syndromes were performed. 418 taxa (213 trees and shrubs, 100 terrestrial herbs, 68 climbing plants, 33 sub-shrubs, two epiphytes, one hemiparasite and one aquatic herb) were recorded. The most representative families were: Fabaceae, Malvaceae, Asteraceae, Rubiaceae and Euphorbiaceae. The annual flowering / fruiting peak hypothesis was not fully confirmed, therefore, the forest may be an important food resource for the fauna all year long (especially in the moister region). Zoochory was the predominant dispersal syndrome in the moister area, whereas, autochory and anemochory together, predominated in the drier area.

ABSTRACT The elderly are more at risk for developing cancer, as aging leaves cells more susceptible to malignant transformations. Identifying frailty can contribute to improved outcomes in antineoplastic treatment. The purpose of this study was to identify the prevalence and degree of frailty in elderly cancer patients undergoing chemotherapy treatment and investigate factors associated with this syndrome. Ambulatory patients> 60 years were included. Frailty was assessed from the phenotype developed by Johns Hopkins University. The significance level adopted for all tests was p<0.05. From the sample of 60 individuals, 55.0% were men, with mean age 69.8 ± 7.6. Among the patients evaluated, 66.7% presented frailty, and 33.3% pre-frailty. Women were more frail (81.5% vs 54.5%; p= 0.028) and frailty tended to be higher among cachectic patients (81.8% vs 57.9%; p= 0.051). We concluded that there was an elevated percentage of frail and pre-frail patients. Female sex and sedentarism were associated factors.

RESUMEN Los ancianos están más expuestos al desarrollo del cáncer, pues el envejecimiento deja las células más susceptibles a la transformación maligna. Identificar la fragilidad puede contribuir a mejorar resultados en el tratamiento antineoplásico. El objetivo de este estudio fue identificar la prevalencia y grado de fragilidad en ancianos oncológicos en tratamiento con quimioterapia e investigar factores asociados al síndrome. Se incluyeron pacientes ≥60 años en nivel ambulatorio. La fragilidad se evaluó a partir del fenotipo desarrollado en la Universidad Johns Hopkins. El nivel de significancia adoptado para todas las pruebas fue menor que p<0,05. De la muestra de 60 individuos, el 55,0% era hombres, con promedio de edad 69,8±7,6. Entre los pacientes evaluados, el 66,7% presentaron fragilidad y el 33,3% pre-fragilidad. Las mujeres fueron más frágiles (81,5% vs 54,5%; p= 0,028) y la fragilidad tendió a ser mayor entre los caquécticos (81,8% vs 57,9%; p= 0,051). Concluimos que hubo un porcentaje elevado de pacientes frágiles y pre-frágiles. El sexo femenino y el sedentarismo se presentaron como factores asociados.

ABSTRACT Sarcopenia is characterized by the triad of reduced muscle mass in association with reduced muscle strength and / or physical performance. Among chronic diseases, cancer is a condition related to the development of sarcopenia because of, among other factors, inflammation, protein catabolism and loss of appetite attributed to the side effects of chemotherapy treatment. Objective: To describe the prevalence of sarcopenia in cancer patients undergoing chemotherapy. Method: A cross-sectional study was carried out with patients of both sexes, in a university hospital in Northeastern Brazil. Sarcopenia was determined by arm circumference (percentile <10); hand grip strength (<20 kg/f and <30 kg/f for women and men, respectively; lowest tertile: <28.7 kg/f and <15.6 kg/f for men and women, respectively) and gait velocity (<0.8 m/s). Sociodemographic, lifestyle, clinical and anthropometric variables were also evaluated. Results: The sample consisted of 117 patients (59.8% female), with a mean age of 60.5 ± 13.2 years. There was a prevalence of sarcopenia of 27.4% and 53.1% had severe sarcopenia. Sarcopenia was more common in older participants (p= 0.003). There was also a positive association with nutritional status (p<0.001). Conclusion: The prevalence of sarcopenia was significant and similar to other studies, being more prevalent in undernourished and elderly participants.

RESUMEN La sarcopenia se caracteriza por la tríada de reducción de masa muscular en asociación con reducción de la fuerza muscular y/o desempeño físico. Entre las enfermedades crónicas, el cáncer se configura como una condición relacionada al desarrollo de la sarcopenia, debido a la condición inflamatoria, al catabolismo proteico y a la inapetencia alimentaria atribuida a los diversos efectos colaterales del tratamiento de quimioterapia. Objetivo: Describir la prevalencia de sarcopenia en pacientes oncológicos en tratamiento quimioterapéutico. Método: Estudio transversal realizado con pacientes de ambos sexos, en un hospital universitario del nordeste brasileño. Se determinó la sarcopenia a través de la circunferencia muscular del brazo (percentil <10); fuerza de prensión palmar: <20 kg/f y < 30 kg/f para mujeres y hombres ancianos respectivamente, menor tercil: <28,7kg/f y <15,6 kg/f para hombres y mujeres adultas respectivamente y velocidad de marcha (<0.8 m/s). Se evaluaron las variables de asociación, como datos sociodemográficos, estilo de vida, clínico y antropométrico. Resultados: La muestra fue compuesta por 117 pacientes, con edad promedio 60,5 ±13,2 años con prevalencia del sexo femenino (el 59,8%). Se verificó una prevalencia de sarcopenia del 27,4%, y se observó que el 53,1% tenían sarcopenia severa. Los ancianos fueron los más sarcopénicos (p= 0,003). Se encontró también una asociación positiva con el estado nutricional (p<0,001). Conclusión: La prevalencia de la sarcopenia fue significativa y semejante a otros estados, siendo más prevalentes en los pacientes desnutridos y ancianos.
