Abstract Global second order effects in reinforced concrete buildings can be estimated using numerical or simplified methods, such as the γz coefficient, presented in the Brazilian standard. This paper proposes a new simplified parameter, which is deduced by the Galerkin’s Method by Weighted Residuals. In order to evaluate the accuracy of the proposed methodology, 42 planar frames (21 framed system structures and 21 dual system structures) were analysed in terms of internal forces and displacements. Such results were compared to those obtained by the γz coefficient and to the reference results obtained throughout a geometric nonlinear elastic finite element program. The precision of the results was defined by statistical analyses, which showed that the results using the proposed parameter were closer to the reference ones, even in the recommended range for using the γz coefficient.

Resumo Efeitos globais de segunda ordem em edifícios de concreto armado podem ser estimados por métodos numéricos ou procedimentos simplificados, como o coeficiente γz, apresentado na norma brasileira. Neste artigo propõe-se um novo parâmetro simplificado, que é deduzido pelo Método de Galerkin por Resíduos Ponderados. De modo a avaliar a acurácia do modelo proposto, 42 pórticos planos (21 com contraventamento por pórticos e 21 com contraventamento por elementos rígidos) foram analisados em termos de esforços internos e deslocamentos. Tais resultados foram comparados aos obtidos pelo coeficiente γz e a resultados de referência obtidos por um programa de elementos finitos com análises de não linearidade geométrica. A precisão dos resultados foi definida por parâmetros estatísticos, que mostram que os resultados obtidos utilizando o parâmetro proposto estavam mais próximos dos resultados de referência, mesmo na faixa recomendada para a utilização do parâmetro γz.

ABSTRACT: In Brazil, urea is the most used nitrogen (N) fertilizer to improve forage production. However, their excessive use can cause environmental impacts through N losses, such as ammonia (NH3) volatilization. Therefore, the current study adjusted and estimated the NH3 volatilization from urea applied on tropical pastures in three rainfall conditions using mathematical models. Data were collected from Marandu grass (Brachiaria brizantha) fertilized with 50 kg N ha-1 during wet, intermediate, and dry conditions. Ammonia volatilization was measured in five semi-open chambers for 21 days. The linear, quadratic, exponential, Gompertz, Groot, and Richards models were tested for fitting and estimating the NH3 volatilization. The Gompertz, Groot, and Richards models generated predictions similar to the observed data, with a high determination coefficient, indicating a better fit of these equations to data, with precision and accuracy. However, the Groot model was selected due to the lowest root mean square error of prediction (0.29 % total N lost as NH3). The greatest N loss as NH3 volatilization occurred in the wet, followed by intermediate and dry conditions (20.2, 17.0, and 11.3 % total N lost as NH3, respectively). Therefore, nitrogen losses as NH3 volatilization after application of 50 kg N ha-1, as urea source, are altered according to the weather conditions, reaching 20% of N added in the wet rainfall period. The Groot model is recommended for fitting and estimating the NH3 volatilization from urea applied on Marandu grass pastures in the wet and dry rainfall conditions.

RESUMO: No Brasil, a ureia é o fertilizante nitrogenado mais utilizado para melhorar a produção de forragem. No entanto, seu uso excessivo pode causar impactos ambientais por meio de perdas de nitrogênio (N), como a volatilização da amônia (NH3). Portanto, o objetivo do presente estudo foi ajustar a volatilização de NH3 da ureia aplicada em pastos tropicais em três condições de chuva utilizando modelos matemáticos. Dados foram coletados de pastos de capim-marandu (Brachiaria brizantha) adubado com 50 kg N ha-1 em condições úmidas, intermediárias e secas. A volatilização da NH3 foi medida em cinco câmaras semiabertas durante 21 dias. Os modelos, linear, quadrático, exponencial, Gompertz, Groot e Richards foram testados para ajuste e estimativa da volatilização do NH3. Os modelos de Gompertz, Groot e Richards geraram predições semelhantes aos dados observados, com alto coeficiente de determinação, indicando um melhor ajuste dessas equações aos dados, com acurácia e precisão. No entanto, o modelo Groot foi selecionado devido ao menor erro quadrático médio das predições (0,29% de N total perdido como NH3). A maior volatilização de NH3 ocorreu em condições climáticas úmida, seguido por intermediária e seca (20,2; 17,0 e 11,3% de N total perdido como NH3, respectivamente). Portanto, as perdas de N como volatilização de NH3 após a aplicação de 50 kg N ha-1, como fonte de ureia, são alteradas de acordo com as condições climáticas, atingindo a 20% do N adicionado nas condições úmidas. O modelo Groot é recomendado para ajuste e estimativa da volatilização de NH3 da ureia aplicada em pastos de capim Marandu em condições úmidas e secas.

Abstract This study aimed to identify the influence of replacing coarse natural aggregate with coarse recycled concrete aggregate on the thickness and volume of the cementitious paste under the variation of the water/cement ratio in the fresh and hardened properties of pervious concrete. The determined theoretical paste thickness was inefficient for pervious concrete dosage. However, it was found that the paste volume was the parameter that was best related to the mechanical and permeability properties of the studied material. Pervious concrete with natural aggregates showed higher compressive strength than concrete with recycled aggregates, although both met the regulations. All the concretes produced, except one with recycled aggregate of w/c ratio 0.25, reached the tensile strength in the minimum design bending. Pervious concrete with recycled aggregates showed more significant mass loss by abrasion and more porosity than concretes with natural aggregates. Finally, all pervious concretes presented permeability coefficients greater than the lower limit determined by the standard.

Resumo Este estudo teve como objetivo identificar a influência da substituição do agregado graúdo natural por agregado graúdo reciclado de concreto na espessura e no volume da pasta cimentícia sob a variação da relação água/cimento nas propriedades frescas e endurecidas do concreto permeável. A espessura teórica da pasta determinada foi ineficiente para dosagem de concreto permeável. Porém, constatou-se que o volume da pasta foi o parâmetro que melhor se relacionou com as propriedades mecânicas e de permeabilidade do material estudado. O concreto permeável com agregados naturais apresentou maior resistência à compressão que o concreto com agregados reciclados, mas ambos atenderam às normas vigentes. Todos os concretos produzidos, exceto com agregado reciclado de relação a/c 0,25, atingiram a resistência à tração na flexão mínima de projeto. O concreto permeável com agregados reciclados apresentou perda de massa mais significativa por abrasão e foi mais poroso que o concreto com agregados naturais. Por fim, todos os concretos permeáveis apresentaram coeficientes de permeabilidade superiores ao limite inferior determinado pela norma.

Resumo Este trabalho analisa as evidências atuais sobre a discriminação percebida por adultos mais velhos (> 50 anos) no uso de serviços de saúde e identifica os fatores associados a essa experiência. Trata-se de uma revisão integrativa da literatura, realizada a partir de pesquisa nos sítios eletrônicos Biblioteca Virtual de Saúde, CINAHL, Medline, Scopus e Web of Science, em junho de 2021. Foram utilizados os descritores: discriminação social ou ageismo; pessoa de meia-idade ou idoso de 80 anos ou mais ou idoso; e serviço de saúde ou serviço de saúde para idosos, incluindo sinônimos, nos idiomas português, inglês e espanhol. A estratégia de busca identificou 1.165 artigos; 19 cumpriram os critérios de elegibilidade e inclusão. O acervo inclui estudos quantitativos e qualitativos publicados entre 2002 e 2021; cerca de 60% realizados nos Estados Unidos e Austrália. A prevalência de discriminação no uso de serviços de saúde variou de 2% a 42%. O relato de práticas discriminatórias se mostrou associado a características étnico-raciais, sexo, idade, orientação sexual, aparência física e classe social. Ao dar visibilidade ao tema, este trabalho visa estimular a definição de formas concretas de enfrentamento à discriminação e interromper a perpetração de iniquidades no âmbito da atenção à saúde.

Abstract This paper analyzes the current evidence on discrimination perceived by elderly adults (> 50 years) in the use of health services and identifies factors associated with this discriminatory experience. It involved an integrative literature review, carried out on the Biblioteca Virtual de Saúde, CINAHL, Medline, Scopus, and Web of Science search websites, in June/2021. The key words used were social discrimination or ageism; middle-aged, or aged 80 and over or elderly; health services or health services for the elderly, including synonyms, in Portuguese, English, and Spanish. The search strategy identified 1,165 articles; 19 met the eligibility and inclusion criteria and were included in this integrative review. They comprise quantitative and qualitative studies published between 2002 and 2021; about 60% carried out in the United States and Australia. The prevalence of discrimination in the use of health services ranged from 2% to 42%. The report of discriminatory practices was associated with ethnic-racial characteristics, sex, age, sexual orientation, physical appearance, and social class. By giving visibility to the theme, this work aims to stimulate the definition of concrete ways to tackle discrimination, in an attempt to interrupt the perpetration of inequities in the health care area.

ABSTRACT BACKGROUND: Social distancing has led to lifestyle changes among older adults during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVES: This study aimed to estimate the prevalence risk of sarcopenia (RS) and investigate its associated factors during the COVID-19 pandemic in older Brazilian adults. DESIGN AND SETTING: Cross-sectional observational analysis of baseline data as part of the Remobilize Study. METHODS: Participants in the study were older adults (≥ 60 years), excluding those who were bedridden or institutionalized. The data collected consisted of answers about the RS (SARC-F), functional status, walking, sedentary behavior (SB), pain, comorbidity, and life space mobility. RESULTS: A total of 1,482 older adults (70 ± 8.14 years, 74% women) participated in the study, and an RS prevalence of 17.1% was found. (95% confidence interval [CI] 15.25–19.15%). The adjusted multivariate model showed a significant association between RS and functional limitation (odds ratio [OR]: 19.05; CI 13.00–28.32), comorbidity (OR: 5.11; CI 3.44–7.81), pain (OR: 4.56; CI 3.33–6.28), total walking (OR: 0.99; CI 0.99–1.00), SB of 8–10 hours (OR: 1.85; CI 1.15–2.93), and SB of > 10 hours (OR: 3.93; CI 2.48–6.22). RS was associated with mobility during the pandemic (OR: 0.97; CI 0.96–0.98). P < 0.05. CONCLUSIONS: During the pandemic, the prevalence of RS in older Brazilians was estimated at 17.1%. Moderate to severe functional limitation, comorbidities, presence of pain, walking, longer SB period, and reduced life space mobility significantly contributed to RS in older adults during the pandemic.

Abstract This purpose of this study was to compare the efficiency of the McMaster and Mini-FLOTAC quantitative techniques in the investigation of helminths in feces of pigs. An analysis was made of 74 fecal samples from pigs raised on family farms located in Rio de Janeiro, Brazil. These were analyzed by the Mini-FLOTAC and McMaster techniques in a solution of 1,200g/mL NaCl. This investigation revealed a superiority in the frequency of all helminths detected by Mini-FLOTAC, including Ascaris suum, Trichuris suis, strongyles and Strongyloides ransomi. The Kappa index revealed substantial agreement in all comparisons made in relation to the frequency of positive samples. However, significant statistical differences in the comparison of EPGs between McMaster and Mini-FLOTAC were observed for all nematodes (p ≤0.05). Higher values of Pearson’s linear correlation coefficient (r), between the techniques in relation to EPG were observed for A. suum and T. suis, differently from what was observed for strongyles and S. ransomi. Mini-FLOTAC proved to be a more satisfactory and reliable technique both for the diagnosis of parasites and for the determination of EPG in pig feces due to the larger size of its counting chambers, thus increasing the helminth egg recovery rates.

Resumo Este estudo objetivou comparar a eficiência das técnicas quantitativas de McMaster e Mini-FLOTAC para a pesquisa de helmintos em fezes de suínos. Foram analisadas 74 amostras fecais de suínos mantidos em propriedades familiares, localizadas no Rio de Janeiro, Brasil. Estas foram analisadas pelas técnicas de Mini-FLOTAC e McMaster com solução de NaCl 1.200g/mL. Pode-se verificar uma superioridade na frequência de todos os helmintos detectados por meio do Mini-FLOTAC, incluindo-se Ascaris suum, Trichuris suis, estrongilídeos e Strongyloides ransomi. O índice Kappa mostrou uma concordância substancial em todas as comparações realizadas, em relação à frequência de amostras positivas. Entretanto, diferenças estatísticas significativas na comparação do OPG entre McMaster e Mini-FLOTAC foram observadas para todos os nematoides (p ≤0.05). Elevados valores do coeficiente de correlação de Pearson foram observados entre as técnicas, em relação ao OPG para A. suum e T. suis, diferentemente do evidenciado para estrôngilos e S. ransomi. Mini-FLOTAC mostrou-se uma técnica mais satisfatória e confiável, tanto para o diagnóstico de parasitos quanto para a determinação do OPG em fezes de suínos, devido ao maior tamanho das suas câmaras de contagem, situação que acaba aumentando a eficiência da recuperação dos ovos dos helmintos.

Abstract This study evaluated the bioactive potential of a macro-porous chitosan scaffold incorporated with calcium hydroxide (CH-Ca) and functionalized with bioactive doses of simvastatin (SV) for bone tissue regeneration. Initially, the bioactive dose of SV in osteoblastic cells (SAOS-2) was determined. For the direct contact experiment, SAOS-2 cells were plated on scaffolds to assess cell viability and osteogenic differentiation. The second assay was performed at a distance using extracts from scaffolds incubated in culture medium to assess the effect of conditioned medium on viability and osteogenic differentiation. The initial screening showed that 1 μM SV presented the best biostimulating effects, and this dose was selected for incorporation into the CH-Ca and pure chitosan (CH) scaffolds. The cells remained viable throughout the direct contact experiment, with the greatest cell density in the CH-Ca and CH-Ca-SV scaffolds because of their higher porosity. The CH-Ca-SV scaffold showed the most intense bio-stimulating effect in assays in the presence and absence of osteogenic medium, leading to an increased deposition of mineralized matrix. There was an increase in the viability of cells exposed to the extracts for CH-Ca, CH-SV, and CH-Ca-SV during the one-day period. There was an increase in ALP activity in the CH-Ca and CH-Ca-SV; however, the CH-Ca-SV scaffold resulted in an intense increase in the deposition of mineralized nodules, approximately 56.4% at 7 days and 117% at 14 days, compared with CH (control). In conclusion, functionalization of the CH-Ca scaffold with SV promoted an increase in bioactivity, presenting a promising option for bone tissue regeneration.

ABSTRACT BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike’s Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.

ABSTRACT AIDS-related disseminated histoplasmosis (DH) can cause septic shock and multiorgan dysfunction with mortality rates of up to 80%. A 41-year-old male presented with fever, fatigue, weight loss, disseminated skin lesions, low urine output, and mental confusion. Three weeks before admission, the patient was diagnosed with HIV infection, but antiretroviral therapy (ART) was not initiated. On day 1 of admission, sepsis with multiorgan dysfunction (acute renal failure, metabolic acidosis, hepatic failure, and coagulopathy) was identified. A chest computed tomography showed unspecific findings. Yeasts suggestive of Histoplasma spp. were observed in a routine peripheral blood smear. On day 2, the patient was transferred to the ICU, where his clinical condition progressed with reduced level of consciousness, hyperferritinemia, and refractory septic shock, requiring high doses of vasopressors, corticosteroids, mechanical ventilation, and hemodialysis. Amphotericin B deoxycholate was initiated. On day 3, yeasts suggestive of Histoplasma spp. were observed in the bone marrow. On day 10, ART was initiated. On day 28, samples of peripheral blood and bone marrow cultures revealed Histoplasma spp. The patient stayed in the ICU for 32 days, completing three weeks of intravenous antifungal therapy. After progressive clinical and laboratory improvement, the patient was discharged from the hospital on oral itraconazole, trimethoprim-sulfamethoxazole, and ART. This case highlights the inclusion of DH in the differential diagnosis of patients with advanced HIV disease, septic shock and multiorgan dysfunction but without respiratory failure. In addition, it provides early in-hospital diagnosis and treatment and comprehensive management in the ICU as determining factors for a good outcome.

ABSTRACT Objective: To verify the association between sociodemographic, clinical, environmental, cognitive, and emotional factors and the decision time of people with ischemic stroke to seek a health service after the onset of symptoms or wake up stroke. Method: Cross-sectional study carried out from March to October 2019, with 304 patients, in a public hospital, a reference in neurology. Data obtained through interview and from medical records. Decision time was analyzed as a geometric mean. In the bivariate and multivariate analyses, linear regression was used and the Akaike Information Criterion was used to select the best model. Statistical significance of 5% was adopted. Results: The geometric mean of decision time was 0.30h (95% CI 0.23–0.39). The final model explained this time in 41%, showing an increase of 0.5 min for people with arterial hypertension; 10.8 min for those who waited for symptoms to improve; 1.4 min for those who were alone at the onset of symptoms; 3.9 min for those at home; 3.2 min for the ones at work; and 2.1 for those on the street/public space. Conclusion: The mean decision time for seeking a health service was high and influenced by clinical, environmental, cognitive, and emotional variables. The results guide nurses regarding health education.

RESUMEN Objetivo: Verificar la asociación entre factores sociodemográficos, clínicos, ambientales, cognitivos, y emocionales y el tiempo de decisión de las personas con accidente cerebrovascular isquémico para buscar un servicio de salud luego del inicio de los síntomas o Wake up stroke Método: Estudio transversal realizado de marzo a octubre de 2019, con 304 pacientes, en un hospital público, referencia en neurología. Datos obtenidos por entrevista y de la historia clínica. El tiempo de decisión se analizó como una media geométrica. En los análisis bivariados y multivariados se utilizó la regresión lineal y el Criterio de Información de Akaike para seleccionar el mejor modelo. Se adoptó una significancia estadística del 5% Resultados: La media geométrica del tiempo de decisión fue de 0,30h (IC 95% 0,23-0,39). El modelo final explicó este tiempo en un 41%, mostrando un aumento de 0,5 min para las personas con hipertensión arterial, 10,8 min para las que esperaron a que los síntomas mejoraran, 1,4 min para las que estaban solas al inicio de los síntomas, 3, 9 min para las que estaban en casa, 3,2 min para los que estaban en el trabajo y 2,1 en la calle/vía pública Conclusión: El tiempo promedio de decisión para buscar un servicio de salud fue alto e influenciado por variables clínicas, ambientales, cognitivas y emocionales. Los resultados orientan a los enfermeros hacia la educación en salud.

Abstract Resolubility relates to the ability to solve health problems in services. In 1999, the Indigenous Health Care Subsystem was integrated into the Brazilian Unified Health System, following its principles and guidelines. The objective of this study was to identify and map the challenges or problems related to health practices for solving in the Indigenous Health Subsystem after integration. This is a scope review that used six national and international databases. Eligible studies were based on mnemonic PCC (P: indigenous population; C: challenges or problems for resolution; C: Brazilian indigenous health subsystem). A total of 1,748 studies were found and 33 were selected, with predominance of qualitative studies. The challenges or problems that are sensitive to the resolution process were found in the aspects that are related to health education, interculturality, universal access and management resources. Traditional knowledge is underrated by the health system. The deficiency of human and material resources, the lack of effective permanent education and capacitations to work in the intercultural context, produce barriers to access and compromise the resolubility in services, thus increasing the inequities in health.

Resumen La resolución se refiere a la capacidad de resolver problemas de salud en los servicios. En 1999, el Subsistema de Atención de Salud Indígena se integró en el Sistema Único de Salud de Brasil, siguiendo sus principios y directrices. El objetivo de este estudio fue identificar y mapear los desafíos o problemas relacionados con las prácticas de salud para resolver en el Subsistema de Salud Indígena después de la integración. Esta es una revisión de alcance que utilizó seis bases de datos nacionales e internacionales. Los estudios elegibles se basaron en PCC mnemónicos (P: población indígena; C: desafíos o problemas para la resolución; C: subsistema de salud indígena brasileño). Se encontraron 1.748 estudios y se seleccionaron 33, con predominio de estudios cualitativos. Los desafíos o problemas que son sensibles al proceso de resolución se encontraron en los aspectos que están relacionados con la educación en salud, la interculturalidad, el acceso universal y los recursos de gestión. El conocimiento tradicional es subestimado por el sistema de salud. La deficiencia de recursos humanos y materiales, la falta de educación permanente efectiva y de capacitaciones para trabajar en el contexto intercultural, producen barreras para acceder y comprometer la solubilidad en los servicios, aumentando así las desigualdades en salud.

Abstract: En | Text: En | PDF: En

ABSTRACT Purpose: this study aimed at assessing the legibility, reliability, usability and coverage of websites on cleft lip and/or palate (CL/P) in Brazilian Portuguese and providing a global comparison. Methods: in order to evaluate the obtained data, four protocols were used, i.e., the Website Coverage Protocol, the legibility (by means of the COH METRIX PORT), the reliability (Discern Protocol), and the usability (by means of the System Usability Scale). Results: 98 websites were included with average legibility scoring of 31.6±11.7, rated as a hard readability level. Coverage average scoring was 19.9±3.79 from a total of 35 points. As for reliability, average scoring was 43.2±6.51 points, rated as acceptable. The usability scoring was 24.8±2.18 points, rated as the worst imaginable one. Conclusion: therefore, the assessed Brazilian websites on CL/P were rated difficult for legibility, requiring high-school level of education, restricted coverage and acceptable reliability, in addition to the low usability. The results were similar to those of websites from other countries, except for the legibility aspect, which was lower for Brazilian websites.
