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 Objetivo. Identificar as recomendações para 2022 dos ministérios da saúde de 13 países e áreas da América do Sul referentes à vacinação contra o papilomavírus humano (HPV) e o rastreamento do câncer do colo do útero. Métodos. Uma revisão sistemática da literatura científica e de documentos oficiais foi realizada entre 7 de julho e 17 de outubro de 2022. A revisão incluiu uma pesquisa inicial em sites oficiais (por exemplo, de ministérios da saúde, institutos nacionais de câncer e departamentos de saúde) de países sul-americanos para identificar diretrizes ou recomendações atuais para a vacinação contra o HPV e o rastreamento do câncer do colo do útero. Resultados. Foram encontradas recomendações de vacinação contra o HPV em 11 países; as exceções foram a Guiana Francesa e a República Bolivariana da Venezuela. Foram encontradas recomendações de rastreamento do câncer do colo do útero em documentos oficiais de 11 países, com exceção da República Bolivariana da Venezuela, onde foi encontrado um artigo que não era uma recomendação oficial, e do Suriname, para o qual não foram encontrados documentos em sites nem em outras publicações. No total, 12 países usam citologia para rastreamento do câncer do colo do útero. Quatro países (Bolívia [Estado Plurinacional da], Colômbia, Guiana e Peru) usam inspeção visual com ácido acético e a estratégia de “Ver e Tratar”. Seis países (Argentina, Chile, Colômbia, Equador, Paraguai e Peru) estão fazendo a transição da citologia para a testagem de HPV. Conclusões. Não foram encontrados documentos sobre nenhum programa nacional de vacinação contra o HPV na Guiana Francesa e na Venezuela, e não foram encontradas diretrizes oficiais de rastreamento do câncer do colo do útero no Suriname e na Venezuela; portanto, será difícil eliminar esse problema de saúde pública nesses países. Os países da América do Sul precisam atualizar suas diretrizes de vacinação contra o HPV e de rastreamento do câncer do colo do útero à medida que surjam novas evidências. Os sites oficiais com informações sobre a vacinação contra o HPV e o rastreamento do câncer do colo do útero são fontes importantes que podem ser acessadas pelos profissionais de saúde e pela população.

RESUMEN Objetivo. Determinar las recomendaciones formuladas en el 2022 por los ministerios de salud de los 13 países y zonas de América del Sur en materia de vacunación contra el virus del papiloma humano (VPH) y detección del cáncer cervicouterino. Métodos. Entre el 7 de julio y el 17 de octubre del 2022 se llevó a cabo una revisión sistemática de publicaciones científicas y documentos oficiales. La revisión comprendió una búsqueda inicial en los sitios web oficiales (por ejemplo, de los ministerios de salud, los institutos nacionales del cáncer y los departamentos de salud) de los países de América del Sur, para determinar las directrices o recomendaciones actuales relativas a la vacunación contra el VPH y la detección del cáncer cervicouterino. Resultados. Se encontraron recomendaciones sobre la vacunación contra el VPH en 11 países, excepto Guayana Francesa y República Bolivariana de Venezuela. Se encontraron recomendaciones sobre la detección del cáncer cervicouterino en documentos oficiales de 11 países, excepto República Bolivariana de Venezuela, donde se encontró un artículo que no era una recomendación oficial, y Suriname, para el cual no se encontraron documentos ni en sitios web ni en otras publicaciones. En 12 países se utiliza la citología como método para la detección del cáncer cervicouterino. En cuatro países (Bolivia [Estado Plurinacional de], Colombia, Guyana y Perú) se utiliza la inspección visual tras la aplicación de ácido acético y la estrategia de detección y tratamiento. En seis países (Argentina, Chile, Colombia, Ecuador, Paraguay y Perú) se está llevando a cabo un proceso de transición, de la citología a la realización de pruebas de detección del VPH. Conclusiones. No se encontraron documentos sobre un programa nacional de vacunación contra el VPH en Guayana Francesa y República Bolivariana de Venezuela, y tampoco se encontraron directrices oficiales para la detección del cáncer cervicouterino en Suriname y Venezuela. En consecuencia, la eliminación de este problema de salud pública en dichos países será una tarea difícil. Los países de América del Sur deben actualizar sus directrices sobre la vacunación contra el VPH y el tamizaje del cáncer cervicouterino a medida que surja nueva evidencia al respecto. Los sitios web oficiales con información sobre la vacunación contra el VPH y la detección del cáncer cervicouterino son fuentes importantes de información que pueden consultar los profesionales de la salud y la población.

ABSTRACT Objective. To identify the 2022 recommendations made by ministries of health in the 13 countries and areas of South America for human papillomavirus (HPV) vaccination and cervical cancer screening. Methods. A systematic review of scientific literature and official documents was conducted between July 7 and October 17, 2022. The review included an initial search on official websites (e.g. ministries of health, national cancer institutes and health departments) of South American countries to identify current guidelines or recommendations for HPV vaccination and cervical cancer screening. Results. Recommendations for HPV vaccination were found for 11 countries, with the exceptions of French Guiana and the Bolivarian Republic of Venezuela. Recommendations were found for cervical cancer screening in official documents from 11 countries, with the exceptions of the Bolivarian Republic of Venezuela, where one article was found that was not an official recommendation, and Suriname, for which no documents were found on websites or in other publications. A total of 12 countries use cytology to screen for cervical cancer. Four countries (Bolivia [Plurinational State of], Colombia, Guyana and Peru) use visual inspection with acetic acid and the screen-and-treat strategy. Six countries (Argentina, Chile, Colombia, Ecuador, Paraguay and Peru) are transitioning from cytology to HPV testing. Conclusions. No documents were found about a national HPV vaccination program in French Guiana and Venezuela, and no official guidelines for cervical cancer screening were found for Suriname and Venezuela; thus, it will be difficult to eliminate this public health problem in these countries. Countries in South America must update their guidelines for HPV vaccination and cervical cancer screening as new evidence emerges. Official websites with information about HPV vaccination and cervical cancer screening are important sources that can be accessed by health professionals and the population.

Abstract Acinetobacter spp. are one of the main pathogens responsible for healthcare-associated infections and are associated with high rates of morbidity and mortality globally, mainly because of their high capacity to present and develop resistance to antimicrobials. To identify species of the Acinetobacter and their resistance profiles from samples collected from hospitalized patients, health professionals and hospital environmental sources in the intensive care units of different public reference hospitals in Porto Velho City, Rondônia, Western Brazilian Amazon. Isolates were identified using microbiological and molecular techniques. The antimicrobial susceptibility profile was determined by disk diffusion. A total of 201 Acinetobacter spp. isolates were identified, of which 47.3% originated from hospital structures, 46.8% from patients and 6% from healthcare professionals. A. baumannii and A. nosocomialis were the most prevalent, with frequency of 58.7% and 31.8%, respectively. Regarding the susceptibility profile, it was observed that 56.3% were classified as multidrug-resistant and 76.2% of the samples belonging to A. baumannii were resistant to carbapenems. In contrast, 96.9% were susceptible to polymyxin B and 91.3% to doxycycline. The data presented here can be used to guide and strengthen the control of multidrug-resistant infections caused by Acinetobacter spp., in addition to improving providing information from a traditionally unassisted region of Brazil.

Abstract This research aimed to understand the experiences and meanings that women attributed to becoming caregivers of dependent older adults, considering the analysis of gender socialization. Qualitative study with 53 family caregivers, carried out from June to September 2019, in the cities of Belo Horizonte, Rio de Janeiro, Porto Alegre, Araranguá, Manaus, Fortaleza, and Teresina. The analysis of the information was guided by the theoretical-methodological framework of hermeneutics-dialectics. The findings were organized into four categories: the caregiver role as something “natural” for women; men absent from the act of caring and maintenance of masculinity; the marital responsibility of wives and gender identity for care; and the economy and cisheteropatriarchy as determinants to undertake care. Women exercise care due to gender socialization. This fact is reinforced by the circumstances of being single, living with the older adults, male absence from sharing care, marital responsibility, and pressure to withdraw from the job market. In conclusion, the family-centered care model is sustained by women, due to the social dynamics built in a capitalist, cisheteropatriarchal-centered society. This indicates the need for society to intervene, reflect, and propose actions for balanced care between men and women.

Resumo Esta pesquisa tem como objetivo compreender as experiências e os sentidos atribuídos pelas mulheres para se tornarem cuidadoras de idosos dependentes, à luz da análise da socialização de gênero. Estudo qualitativo com 53 cuidadoras familiares, realizado de junho a setembro de 2019, nas cidades de Belo Horizonte, Rio de Janeiro, Porto Alegre, Araranguá, Manaus, Fortaleza e Teresina. A análise das informações guiou-se pelo referencial teórico-metodológico da hermenêutica-dialética. Os achados foram organizados em quatro categorias: a função cuidadora como algo “natural” da mulher; homens ausentes no ato de cuidar e a manutenção da masculinidade; a responsabilidade marital de esposas e a identidade de gênero para o cuidar; a economia e o cisheteropatriarcado como norteadores para assumir o cuidado. As mulheres exercem o cuidado em decorrência da socialização de gênero. Esse fato é potencializado pelas circunstâncias de estarem solteiras, residirem com a pessoa idosa, ausência masculina na partilha do cuidado, responsabilidade marital e pressão para se retirarem do mercado de trabalho. Em conclusão, o modelo de cuidado centrado na família é sustentado pelas mulheres devido as dinâmicas sociais construídas em uma sociedade capitalista e centrada no cisheteropatriarcado. Isto sinaliza para a necessidade de a sociedade intervir, refletir e propor ações para um cuidado equilibrado entre homens e mulheres.

Abstract The aim of this study is to report an original case series of synchronous jawbone diseases. Data of patients seen over 13 years were extracted from the files of three Oral Radiology and Pathology diagnostic centers in Brazil. The clinical, radiographic, and laboratory characteristics were tabulated and analyzed by the authors; the patients were described according to lesion type. Seventy-two synchronous jawbone diseases were included in this study. Florid osseous dysplasia, Gorlin-Goltz syndrome, and cherubism were the most frequent disorders reported in this case series. In addition, the posterior mandible area was the main site of manifestation. Florid osseous dysplasia and Gorlin-Goltz syndrome represented two-thirds of our samples. With the utilization of adequate demographic, clinical, and radiologic information, it is possible to diagnose most of the synchronous lesions of jawbones. Sometimes, however, we need complementary exams, such as histopathologic and biochemical analysis or dosing of calcium, phosphorus, and alkaline phosphatase.

Abstract: En | Text: En | PDF: En

Abstract Oral cancer is a public health problem worldwide with approximately 300,000 new cases diagnosed every year and more than 170,000 deaths annually. Squamous cell carcinoma (SCC) accounts for approximately 90% of all oral malignancies and it is frequently preceded by lesions known as oral potentially malignant disorders (OPMDs). Screening programs for early detection of oral lesions have been conducted. Therefore, the objective of this research was to carry out an active search in a screening program in the city of Piracicaba, Brazil. High-risk patients were identified at the city’s health center through their medical records and referred for dental consultation. Other patients who opportunistically sought dental care were also seen and if they did not present risk factors for SCC, they were considered low-risk. A total of 756 patients were examined, and 445 met the criteria for the high-risk group and 311 for the low-risk group. It was possible to diagnose 27 OPMDs and six SCCs – 21 OPMDs and six SCCs occurred in high-risk patients and six OPMDs in low-risk patients. A chi-square test was applied and a statistically significant value (p = 0.006) was obtained for the detection of OPMD and SCC in patients of the high-risk group. Screening of high-risk patients through active search proved to be an effective program for diagnosing OPMD and SCC. Therefore, we encourage its implementation on a large scale to reduce the current scenario of this disease.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

ABSTRACT Objective To evaluate the predictive value of positron emission computed tomography or magnetic resonance (PET-CT and PET-MRI) using gallium-68-labeled prostate-specific membrane antigen (68Ga-PSMA) in lymph node involvement in prostate cancer. Methods A retrospective study comprising 91 patients diagnosed with prostate cancer between 2016 to 2020, who underwent 68Ga-PSMA PET-CT or PET-MRI for staging before prostatectomy. The patients were divided into Group 1, with 65 patients with satisfactory pathological lymph node analysis, and Group 2, with 91 patients representing the sum of patients with pathological lymph node analysis and those with postoperative prostate-specific antigen within 60 days after surgery. Receiver Operating Characteristic curves were used to assess accuracy of predictive capacity of imaging exams for lymph node involvement. Results Regarding local clinical staging, the groups showed similar results, and 50% were classified as staging T2a. The accuracy of 68Ga-PSMA PET-CT for prostate cancer lymph node staging was 86.5% (95%CI 0.74-0.94; p=0.06), with a sensitivity of 58.3% and specificity of 95%. The accuracy of 68Ga-PSMA PET-MRI was 84.6% (95%CI 0.69-0.94; p=0.09), with a sensitivity of 40% and specificity of 100%. Considering both 68Ga-PSMA PET-CT and PET-MRI, the accuracy was 85.7% (95%CI 0.76-0.92; p=0.015), with sensitivity of 50% and specificity of 97%. Conclusion The imaging tests 68Ga-PSMA PET-CT and PET-MRI were highly accurate to detect preoperative lymph node involvement, and could be useful tools to indicate the need for extended lymph node dissection during radical prostatectomy.

Abstract Solid residues from agroindustry often accumulate and cause environmental imbalance. An alternative to this is to use this residue as a reinforcement in polymers. The achievement of this work was to characterize a composite with a polystyrene matrix reinforced with Brazil nut shells residues. The residues were cleaned and ground to then produce the samples via injection molding with the proportions of 0%, 2.5% and 5% of load. The specimens were characterized using mechanical tensile testing and thermogravimetric analysis (TGA). The mechanical test showed that the composite with 2.5% of filler had greater stiffness and strength was improved by 5%. Thermal analysis showed an increase in the temperature for the beginning of the degradation of the M2.5 composite. The results confirm a potential application in the automotive industry for the polystyrene composite reinforced with Brazil nut shells.

RESUMO Foram realizados dois ensaios experimentais para avaliar a inclusão de biofermentado a base de plantas do semiárido na dieta de leitões na fase inicial. No ensaio I foi avaliado o valor nutricional e a digestibilidade dos nutrientes e os valores de energia digestível e metabolizável do biofermentado. Para tanto, foram utilizados oito leitões com peso médio inicial de 15,2 ± 2,7 kg, alojados em gaiolas de metabolismo, utilizou-se o método de coleta total de fezes e urina. O biofermentado apresentou 80,40% e 68,18% como coeficientes de digestibilidade para a matéria seca e fibra bruta, respectivamente; 10,08% de proteína bruta e 2.865 kcal/kg de energia metabolizável. No segundo ensaio foi avaliada a inclusão de 0; 3; 6 e 9% de biofermentado sobre o desempenho, incidência de diarreia, componentes plasmáticos, peso e comprimento de órgãos digestivos de leitões na fase inicial. Para tanto, foram utilizados 40 leitões com peso médio inicial de 12,6±3,5 kg, distribuídos em delineamento em blocos casualizados com quatro tratamentos, cinco repetições e dois animais por unidade experimental. A inclusão dos diferentes níveis de biofermentado não afetou (P>0,05) o desempenho, o peso e comprimento dos órgãos digestivos e parâmetros séricos. No entanto, a inclusão do biofermentado reduziu (P<0,01) a incidência de diarreia. Conclui-se que o biofermentado a base de plantas adaptadas ao semiárido apresenta potencial de ser utilizado em dietas para suínos na fase inicial.

ABSTRACT Two experimental tests were carried out to evaluate the inclusion of a biofermented semi-arid plant mix in diets of piglets in the initial weaning phase. In the first trial, the nutritional value and digestibility of nutrients and the digestible and metabolizable energy values of the bio-fermented plants mix were evaluated. To do so, eight piglets with an initial average weight of 15.2 ± 2.7 kg were used, housed in metabolic cages, and using the total collection of feces and urine. The bio-fermented plant mix diet presented 80.40% and 68.18% as digestibility coefficients for dry matter and crude fiber, respectively; 10.08% crude protein and 2,865 kcal/kg of metabolizable energy. In the second trial, the inclusion of 0, 3, 6 and 9% of bio-fermented plant mix was evaluated on performance, diarrhea incidence, plasma components, weight, and length of digestive organs of piglets in the initial weaning phase. To do so, 40 piglets with an initial average weight of 12.6 ± 3.5 kg were used, distributed in a randomized block design with four treatments, five replicates, and two animals per experimental unit. The inclusion of different levels of bio-fermented plant mix did not affect (P>0.05) the performance, weight, and length of digestive organs or serum parameters. However, the inclusion of bio-fermented plant reduced (P<0.01) the diarrhea incidence. It is concluded that bio-fermented plants adapted to the semi-arid region has the potential to be used in diets for pigs in the initial weaning phase.

Abstract: En | Text: En | PDF: En

Fullerene is considered to be the third carbon allotrope after diamond and graphite. The study of fullerene derivatives has been growing due to their exceptional electron affinity. This work proposes th study of three different fullerene derivatives, being phenyl-C61-butyric acid methyl ester (PCBM), oligo {(phenyl-C61-butyric acid methyl ester)-alt-[1,4-bis(bromomethyl)-2,5-bis(octyloxy)benzene]} (OPCBMMB) and poly {[bispyrrolidino(phenyl-C61-butyric acid methyl ester)]-alt-[2,5-bis(octyloxy)benzene]} (PPCBMB), and their application as NH3 sensors. Experimental results showed that these materials have a reproducible response to NH3, with PCBM resulting in the highest observed current peak, followed by OPCBMMB and PPCBMB. These results imply that PCBM, OPCBMMB and PPCBMB can be used to produce NH3 sensors.

RESUMO Danos causados por doenças que ocorrem durante os estádios vegetativos no milho resultam em redução do rendimento de grãos, e o controle químico é uma das estratégias que possibilita a redução dos danos. O objetivo desse trabalho foi quantificar o dano em milho em função da redução da área foliar causada pelo complexo de doenças, associando ou não a remoção de folhas em diferentes posições da planta. O experimento foi conduzido no campo, no delineamento de blocos casualizados com quatro repetições e tratamentos dispostos em arranjo fatorial 10 x 3. O primeiro fator correspondeu a associação de dois fungicidas em diferentes doses, combinados com desfolhas artificiais realizadas nas plantas no momento da primeira aplicação. O segundo fator consistiu em diferentes estádios de aplicação (VT, R1 e R2). O híbrido utilizado foi o Fórmula TL®, suscetível à cercosporiose, ferrugem polissora e mancha-branca. Foi avaliado o progresso das doenças, índice de área foliar e o rendimentos de grãos. Aplicações preventivas (estádio fenológico VT) de fungicidas, independentemente da remoção de folhas na planta, proporcionou menor progresso das doenças e menores danos. Maiores valores significativo de massa de grãos e produtividade foram obtidos com uso de fungicidas sem a remoção de folhas, independentemente do estádio fenológico da aplicação.

ABSTRACT Damage caused by diseases that occur during the vegetative stages of corn results in decreased grain yield, and chemical control is one of the strategies to allow damage reduction. The objective of this study was to quantify the damage to corn plants as a function of leaf area reduction caused by the disease complex, associated or not with leaf removal from different positions in the plant. The experiment was carried out in the field, in a completely randomized block design with four replicates and 10 x 3 factorial arrangement of treatments. The first factor corresponded to the association of two fungicides at different doses, combined with artificial defoliation at the first fungicide spraying. The second factor consisted of application at different stages (VT, R1 and R2). The used hybrid was Formula TL®, which is susceptible to cercosporiosis, polysora rust and white spot. Disease progress, leaf area index and grain yield were evaluated. Preventive application of fungicides (phenological stage VT), regardless of leaf removal from the plant, provided less disease progress and less damage. Higher significant values of grain mass and yield were obtained with fungicide application without leaf removal, regardless of the phenological stage receiving the application.
