RESUMO As antocianinas presentes no açaí podem manchar o cimento de ionomero de vidro modificado por resina (CIVMR) devido a baixa resistencia ao manchamento do material. Objetivo O objetivo desse estudo foi avaliar se o açaí compromete a cor e a rugosidade de superficie de um CIVMR in vitro. Materials e Método Amostras (2 mm de espessura, 8 mm de diámetro) de Vitremer™ (3M ESPE, St Paul, MN, USA) foram preparadas de acordo com as instrugoes do fabricante. O materialfoi espatulado, inserido em um molde de silicone colocado entre duas tiras de poliestireno e fotopolimerizado. Após, as amostras foram randomizadas e alocadas em tres grupos (n=25) de acordo com as solugoes usadas para a degradagao química: saliva artificial (controle) e sorbet de açaí e suco de açaí. Utilizou-se o espectrofotometro CM-2600d/2500d (Konica Minolta, Tokyo, Japan) para a análise da cor (escala CIELa*b*) e o rugosímetro Surfcorder SE 1700 (Kosaka Corp, Tokyo, Japan) para a rugosidade de superficie (Ra, mm). As amostras foram submetidas a tres imersoes diárias (6 ml, 15 minutos) em cada solugao por 14 dias a 37°C, tendo sido lavadas em água destilada e mantidas em saliva fresca (30 minutos) nos intervalos. Após a terceira imersao no dia, as amostras foram mantidas em saliva renovada até o dia seguinte. As variáveis foram analisadas antes (L*, a*, b*, Ra) e depois da degradagao química (L’*, a’*, b’*, Ra’). Resultados Os valores de pH da saliva, sorbet e suco foram, respectivamente 7,0, 3,8 e 4,9. Houve diferenga significante para ΔE* entre saliva (p=0.005) e suco (p=0.002) e entre suco e sorbet (p=0.019), mas nao entre saliva e sorbet (p=0.401). Nao foi observada diferenga significante para Δb* entre as solugoes. Nao houve diferenga significante para Δa* entre suco e sorbet, mas eles foram significativamente diferentes da saliva (p<0.001). A luminosidade (L*) mostrou alteragao significante. O suco mostrou os maiores valores de ΔE* (7,8) e ΔL* (7,7)”. Nao houve mudanga significante para a rugosidade e nao foi observada diferenga significante entre as solugoes para ARa (p>0.05). Conclusao O açaí e a saliva causaram manchamento inaceitável do glaze do CIVMR e insignificante alteragao da rugosidade.

ABSTRACT Coloured compounds (anthocyanins) in açaí can stain resin-modified glass-ionomer cement (RMGIC) due to its low staining resistance. Aim The aim of this study was to assess whether açaí compromises the surface colour and roughness of RMGIC in vitro. Materials and Method Disc-shaped specimens (2 mm thick, 8 mm in diameter) of Vitremer™ (3M ESPE, St Paul, MN, USA) were prepared according to the manufacturer ’s instructions. The mixture was inserted into a silicone mouldplaced between two mylar strips, and light cured. Specimens were randomly divided into three groups (n=25) according to the solutions to be used for chemical degradation: artificial saliva (control), açaí sorbet and açaí juice. A spectrophotometer CM-2600d/2500d (Konica Minolta, Tokyo, Japan) was used to analyse the colour (CIELa*b* scale). Surface roughness (Ra, mm) was measuredusing theprofilometer Surfcorder SE 1700 (Kosaka Corp, Tokyo, Japan). The specimens were subjected to three daily soaks (6 ml, 15 minutes) for 14 days at 37°C. They were washed in distilled water and placed in fresh saliva (30 minutes in the interval). After the third soak in a day, they were stored in fresh saliva overnight. Outcomes were analysed at baseline (L*, a*, b*, Ra) and after degradation (L’*, a’*, b’*, Ra’). Results The pH values of saliva, sorbet, and juice were 7.0, 3.8, and 4.9, respectively. ΔE* values were 6.6 for saliva, 6.9 for sorbet and 7.8 for juice. There was a significant ΔE* difference between saliva (p=0.005) and juice (p=0.002), and between juice and sorbet (p=0.019), but none between saliva and sorbet (p=0.401). There was no significant Δb* difference between the solutions. No difference between juice and sorbet was observed for Δa*, but they were significantly different from saliva (p<0.001). Brightness (L*) changed significantly. Juice showed the highest ΔE* (7.8) and ΔL* (7.7). No significant change was observed for roughness and there was no difference between the solutions for ARa. Conclusions Açaí and saliva led to unacceptable staining, but no significant roughness changes in the resin-modified glass-ionomer cement.

RESUMO OBJETIVOS Explorar a estrutura interna e analisar evidências de invariância de mensuração do formulário de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan) para crianças de seis a 23 meses. MÉTODOS Utilizaram-se microdados do Sisvan de 2015 a 2019. Após análise de adequação da amostra, realizou-se análise fatorial (AF) exploratória considerando valores de cargas fatoriais (≥ 0,30 e < 0,85), comunalidade (> 0,20) e índices de ajuste do modelo – índice de Tucker-Lewis (TLI) > 0,90 e raiz do erro quadrático médio de aproximação (RMSEA) < 0,08. Empreendeu-se uma análise crítica aos itens do formulário para adequação dos parâmetros. A estabilidade de mensuração foi investigada entre grupos etários, macrorregiões e longitudinalmente por AF confirmatória multigrupo em modelos de invariância configural, métrica e escalar. A invariância configural foi aceita se RMSEA < 0,08 e TLI e índice de ajuste comparativo (CFI) > 0,90. Invariâncias métrica e escalar foram aceitas se ΔRMSEA < 0,015 e ΔCFI < 0,01, comparando-se ao modelo anterior. RESULTADOS Após análise crítica, itens do formulário foram agrupados (legumes e verduras; carnes ou ovos e fígado) e excluídos (comida de sal; mingau com leite; arroz, batata, inhame, mandioca, farinha ou macarrão). O modelo exploratório compreendeu três fatores: alimentação complementar saudável (frutas; hortaliças; vegetal ou fruta alaranjados ou folhas verdes escuras; carnes, vísceras ou ovo; feijão), ultraprocessada (iogurte; hambúrguer e/ou embutidos; bebidas adoçadas; macarrão instantâneo, salgadinhos de pacote ou biscoitos salgados; biscoito recheado, doces ou guloseimas), e láctea (leite do peito; outro leite), com cargas fatoriais, comunalidades e ajuste satisfatórios (TLI: 0,918, RMSEA: 0,071). O instrumento reformulado foi estável nos modelos de invariância testados. CONCLUSÕES Com a incorporação das modificações ao formulário do Sisvan, os marcadores subsidiam uma interpretação mais adequada da situação alimentar de crianças de seis a 23 meses.

ABSTRACT OBJECTIVE To explore the internal structure and analyze evidence of measurement invariance of the Sisvan form of food intake markers of the Food and Nutrition Surveillance System (Sisvan) for children aged six to 23 months. METHODS Sisvan microdata from 2015 to 2019 were used. After analyzing sample adequacy, exploratory factor analysis was carried out considering factor loadings (≥ 0.30 and < 0.85), communality (> 0.20), model fit indices – Tucker-Lewis index (TLI) > 0.90, and root mean square error of approximation (RMSEA) < 0.08. A critical analysis of the form items was performed to adjust the parameters. Measurement stability was investigated between age groups, macro-regions and longitudinally by multi-group confirmatory factor analysis in configural, metric, and scalar invariance models. Configural invariance was accepted if RMSEA < 0.08 and TLI and comparative fit index (CFI) > 0.90. Metric and scalar invariances were accepted if ΔRMSEA < 0.015 and ΔCFI < 0.01, compared to the previous model. RESULTS After critical analysis, items were grouped (vegetables and leafy greens; meat or eggs and liver) and excluded (salty food; porridge with milk; rice, potatoes, yams, cassava, flour, or pasta). The exploratory model comprised three factors: healthy complementary feeding (fruit; vegetables; orange or dark green leafy vegetables or fruits; meat, offal, or egg; beans), ultra-processed (yogurt; hamburger and/or sausages; sweetened drinks; instant noodles, packet snacks, or salty cookies; sandwich cookies, sweets, or treats), and milk feeding (breast milk; other milk), with satisfactory factor loadings, communalities and fit (TLI: 0.918, RMSEA: 0.071). The reformulated instrument was stable in the invariance models tested. CONCLUSIONS With the incorporation of the modifications to the Sisvan form, the food intake markers subsidize a more adequate interpretation of the feeding situation of children aged six to 23 months.

Abstract: This study aimed to investigate the association between sociodemographic and behavioral factors and obesity from 2014 to 2021 in adults in São Paulo city, Brazil. A prospective study was carried out with 1,241 adults aged 18 years or above who lived in São Paulo and participated in the São Paulo Health Survey cohort (ISA) - Physical Activity and Environment. The outcome was obesity (yes/no), classified by body mass index and specific cut-off points for each age group. The exposure variables included sex, age, education, skin color, marital status, regional health coordination, physical activity in the four domains, and sedentary behaviors. Multilevel logistic regression models were used for longitudinal analysis. This study found a significant increase (27.7%) in the prevalence of obesity (from 22.6% to 28.9%). People who practiced at least 150 minutes of leisure-time physical activity per week (OR = 0.44; 95%CI: 0.26; 0.76), between 10 and 150 minutes per week of commuting physical activity (OR = 0.49; 95%CI: 0.30; 0.80), and had no partner (OR = 0.47; 95%CI: 0.28; 0.78) were less likely to be obese. People aged from 40 to 59 years (OR = 5.00; 95%CI: 2.02; 12.38) and who were black (OR = 4.70; 95%CI: 1.85; 11.95) were more likely to be obese. This study found an increase in the prevalence of obesity during the studied period, with increased odds for middle-aged and black people and decreased odds for those without a partner and those who practice physical activities in their leisure and as a form of commuting. These results can contribute to support programs and policies to control obesity.

Resumen: El objetivo fue investigar la asociación entre factores sociodemográficos y conductuales y la presencia de la obesidad entre 2014 y 2021 en adultos de la ciudad de São Paulo, Brasil. Se realizó un estudio prospectivo con 1.241 adultos paulistanos, con 18 años o más, participantes de la cohorte Encuesta de Salud de São Paulo (ISA) - Actividad Física y Ambiente. El resultado fue obesidad (sí/no), clasificada a través del índice de masa corporal y con puntos de corte específicos para cada grupo de edad. Las variables de exposición fueron: sexo, edad, escolaridad, color de la piel, estado civil, coordinación regional de salud, actividad física en los cuatro dominios y comportamientos sedentarios. Para los análisis longitudinales se utilizaron modelos de regresión logística multinivel. Hubo un aumento significativo del 27,7% en la prevalencia de la obesidad (del 22,6% al 28,9%). Las personas que practicaron al menos 150 minutos semanales de actividad física por ocio (OR = 0,44; IC95%: 0,26; 0,76), entre 10 y 150 minutos semanales de actividad física de desplazamiento (OR = 0,49; IC95%: 0,30; 0,80) y sin compañero(a) (OR = 0,47; IC95%: 0,28; 0,78) tuvieron menos probabilidades de tener obesidad. Las personas entre 40 y 59 años (OR = 5,00; IC95%: 2,02; 12,38) y de color de piel negra (OR = 4,70; IC95%: 1,85; 11,95) presentaron mayores probabilidades de tener obesidad. El estudio identificó un aumento en la prevalencia de la obesidad durante ese período, con un aumento en las posibilidades para las personas de mediana edad y color de la piel negra, y una disminución en las posibilidades para las personas que viven sin pareja y para las que realizan actividades físicas por ocio y como forma de desplazamiento. Estos resultados pueden contribuir a apoyar los programas y políticas para el control de la obesidad.

Resumo: O objetivo foi investigar a associação entre fatores sociodemográficos e comportamentais e a ocorrência da obesidade entre 2014 e 2021 em adultos da cidade de São Paulo, Brasil. Realizou-se estudo prospectivo com 1.241 adultos paulistanos, com 18 anos ou mais, participantes da coorte Inquérito de Saúde de São Paulo (ISA) - Atividade Física e Ambiente. O desfecho foi obesidade (sim/não), classificada por meio do índice de massa corporal e com pontos de corte específicos para cada faixa etária. As variáveis de exposição foram: sexo, idade, escolaridade, cor da pele, estado marital, coordenadoria regional de saúde, atividade física nos quatro domínios e comportamentos sedentários. Foram utilizados modelos de regressão logística multinível para a análise longitudinal. Houve aumento significativo de 27,7% na prevalência de obesidade (de 22,6% para 28,9%). Pessoas que praticavam ao menos 150 minutos semanais de atividade física no lazer (OR = 0,44; IC95%: 0,26; 0,76), entre 10 e 150 minutos semanais de atividade física de deslocamento (OR = 0,49; IC95: 0,30; 0,80) e sem companheiro(a) (OR = 0,47; IC95%: 0,28; 0,78) tiveram menos chances de ter obesidade. Pessoas entre 40 e 59 anos (OR = 5,00; IC95%: 2,02; 12,38) e de cor de pele preta (OR = 4,70; IC95%: 1,85; 11,95) apresentaram maiores chances de ter obesidade. O estudo identificou um aumento na prevalência de obesidade durante o período, com aumento nas chances para pessoas de meia idade e cor da pele preta, e diminuição nas chances para pessoas que vivem sem companheiro(a) e para praticantes de atividades físicas no lazer e como forma de deslocamento. Esses resultados podem contribuir para dar suporte a programas e políticas para o controle da obesidade.

ABSTRACT Objective: We aimed to analyze the association of diabetes and subclinical hypothyroidism with subclinical atherosclerosis measured by coronary artery calcium (CAC) in the baseline of the ELSA-Brasil study. Materials and methods: CAC was measured using a 64-detector computed tomographic scanner. The association of CAC > 0 was presented as an odds ratio (OR) and 95% confidence intervals (95%CI) in logistic models and as β (95%CI) in linear models after multivariable adjustment for confounders. Results: We analyzed 3,809 participants (mean-age (SD) 50.5 (8.8); 51.7% women). In the main analysis, we did not find an association of diabetes and subclinical hypothyroidism with CAC. However, in stratified analysis according to age strata, we found no significative interaction terms, an important heterogeneity between the groups, with the younger age strata showing an association of the group with both diseases and CAC > 0 (OR 7.16; 95%CI, 1.14; 44.89) with a wide but significative 95%CI, suggesting that the smaller number of participants in the younger group may influence the results. Our findings also showed an association of CAC > 0 and log (CAC+1) with diabetes in logistic (OR, 1.31; 95%CI, 1.05-1.63) and linear models (β, 0.24, 0.16, 0.40), respectively. Diabetes was independently associated with CAC > 0 in linear models. Discussion: In conclusion, our results showed a great heterogeneity in stratified analysis based on age in the younger age strata. Although we found no significant interaction factors, the smaller sample size for the analysis may influence the negative findings.

Resumo O objetivo é avaliar o efeito de diferentes tratamentos superficiais e do envelhecimento na resistência ao cisalhamento da zircônia ultratranslúcida. Foram confeccionados 36 blocos de zircônia ultratranslúcida (7x7x2mm) e sinterizados. Em seguida, divididos em 12 grupos de acordo com o “tratamento de superfície” (C-Primer; Al-Jateamento com Al2O3+Primer; Si-Silicato+Primer; Gl -Glaze+HF+Primer; Z-Zirlink; Zp-Zirlink+Primer) e fatores de “armazenamento” (ST-com, 150 dias/37º e sem). Após o tratamento superficial, foram construídos cinco cilindros (Ø=2mm; h=2,0mm) de cimento resinoso (n=15) em cada bloco cerâmico; ao final foi realizado o ensaio de resistência ao cisalhamento (1mm/min, 50Kgf) e análise de falhas superficiais. Foram confeccionadas 60 amostras adicionais (2x2x2mm) para análises extras (rugosidade superficial, MEV e EDS). Os dados de resistência de união e rugosidade superficial foram avaliados estatisticamente por ANOVA (2 fatores/1fator), teste de Tukey (5%) e análise de Weibull, respectivamente. ANOVA (2 fatores) revelou que todos os fatores foram estatisticamente significativos para a resistência de união. Os grupos de silicatização (SiST: 30,47AMPa; Si: 29,21AMPa) apresentaram os maiores valores de resistência de união, independente do armazenamento (Tukey). Enquanto os grupos tratados com Zirlink (ZST: 2,76FMPa; Z: 5,27EFMPa) apresentaram os valores mais baixos, apenas semelhantes ao grupo GlST (5,14EFMPa). O módulo de Weibull (m) apresentou diferença estatística entre os grupos (p=0,000). A ANOVA (1 fator) revelou que o fator “tratamento superficial” (p=0,0000) foi estatisticamente significativo para rugosidade superficial. Portanto, a aplicação de Zirlink e do Glaze na zircônia pré-sinterizada não promoveu adesão eficiente da zircônia ultratranslúcida ao cimento resinoso, mesmo quando associada a primer contendo MDP.

Abstract The objective is to evaluate the effect of different surface treatments and storage on the shear strength of ultratranslucent zirconia. 36 blocks of ultra-translucent zirconia were fabricated (7x7x2mm) and sintered. Then, divided into 12 groups according to the “surface treatment” (C -Primer; Al -Sandblasting with Al2O3 + Primer; Si -Silicate + Primer; Gl -Glaze + HF + Primer; Z -Zirlink; Zp -Zirlink + Primer) and “storage” factors (ST-with 150 days/37º and without). After surface treatment, five cylinders (Ø=2mm; h=2.0mm) of resin cement (n=15) were constructed in each ceramic block; at the end, the shear strength test was performed (1mm/min, 50Kgf), and analysis of surface failures. 60 additional samples (2x2x2mm) were made for extras analysis (surface roughness, MEV, and EDS). Bond strength and surface roughness data were statistically evaluated by ANOVA (2 factors/1 factor), Tukey test (5%), and Weibull analysis, respectively. ANOVA (2-way) revealed that all factors were statistically significant for bond strength. The silicatization groups (SiST: 30.47AMPa; Si: 29.21AMPa) showed the highest bond strength values, regardless of storage (Tukey's test). While the groups treated with Zirlink (ZST: 2.76FMPa; Z: 5.27EFMPa) showed the lowest values, just similar to the GlST group (5.14EFMPa). The Weibull modulus (m) showed a statistical difference between groups (p=0.000). ANOVA (1 factor) revealed that the "surface treatment" factor (p=0.0000) was statistically significant for surface roughness. Therefore, the application of Zirlink and Glaze on pre-sintered zirconia did not promote efficient adhesion of the ultratranslucent zirconia to the resin cement, even when associated with a primer containing MDP.

Abstract Background: The optimal amount for initial fluid resuscitation is still controversial in sepsis and the contribution of non-resuscitation fluids in fluid balance is unclear. We aimed to investigate the main components of fluid intake and fluid balance in both survivors and non-survivor patients with septic shock within the first 72 hours. Methods: In this prospective observational study in two intensive care units, we recorded all fluids administered intravenously, orally, or enterally, and losses during specific time intervals from vasopressor initiation: T1 (up to 24 hours), T2 (24 to 48 hours) and T3 (48 to 72 hours). Logistic regression and a mathematical model assessed the association with mortality and the influence of severity of illness. Results: We included 139 patients. The main components of fluid intake varied across different time intervals, with resuscitation and non-resuscitation fluids such as antimicrobials and maintenance fluids being significant contributors in T1 and nutritional therapy in T2/T3. A positive fluid balance both in T1 and T2 was associated with mortality (p = 0.049; p = 0.003), while nutritional support in T2 was associated with lower mortality (p = 0.040). The association with mortality was not explained by severity of illness scores. Conclusions: Non-resuscitation fluids are major contributors to a positive fluid balance within the first 48 hours of resuscitation. A positive fluid balance in the first 24 and 48 hours seems to independently increase the risk of death, while higher amount of nutrition seems protective. This data might inform fluid stewardship strategies aiming to improve outcomes and minimize complications in sepsis.

RESUMEN El déficit de conocimientos entre los profesionales de la salud ha sido una barrera para la expansión e implementación de los servicios de rehabilitación pulmonar (RP) a pesar de sus beneficios comprobados para las personas con enfermedad respiratoria crónica (ERC). Este estudio de encuesta forma parte de un proyecto más amplio para implantar la RP en el sistema público sanitario brasileño mediante la evaluación de la preparación de los profesionales sanitarios de dos municipios brasileños para proporcionarla. Se utilizó un cuestionario autoadministrado para evaluar los conocimientos (19 preguntas), la formación (7 preguntas), la confianza (10 preguntas) y la experiencia clínica (8 preguntas) de los fisioterapeutas (FT) y del equipo multiprofesional (EM), aplicado previamente en un taller sobre RP. La puntuación media de los conocimientos fue de 10±3 para FT y de 6±3 para EM. Menos de un tercio de los FT afirmaron que tenían “mucha” experiencia (25%) y confianza (22,7%) para realizar la RP, así como formación suficiente para realizar la prueba de la marcha de seis minutos (27,3%). Pocos profesionales del EM declararon que tenían “mucha” experiencia (10%) y formación suficiente (4,8%) para realizar la RP, así como para planificar el programa educativo (10%) y tenían confianza para derivar a pacientes para la RP (6,5%). Este es el primer estudio que evalúa la preparación de los profesionales de la red pública de salud en Brasil para proporcionar la RP, y se observa que, en los municipios donde se realizó, tanto los FT como el EM están poco preparados para llevarla a cabo, lo que refuerza la necesidad de una formación continuada.

ABSTRACT The knowledge deficit of health professionals has been a barrier to expanding and implementing of pulmonary rehabilitation (PR) services, despite the reported benefits of PR for individuals with Chronic Respiratory Disease (CRD). This study aims to assess the preparedness of health care professionals from two Brazilian cities to perform PR in the public health system. This is survey is part of a larger project to implement PR in the Brazilian public health system. A self-administered questionnaire was used to assess the knowledge (19 questions), training (7 questions), confidence (10 questions), and clinical experience (8 questions) of physical therapists (PT) and the multiprofessional team (MT) before a PR workshop. In total, 44 PT and 231 MT answered the questionnaire. The mean total knowledge score was 10±3 for PT and 6±3 for MT. Few physical therapist reported having “a lot” of experience (25%) and confidence (22.7%) to perform PR, as well as sufficient training to conduct the six-minute walk test (27.3%).Even fewer MT reported having “a lot” of experience (10%) and sufficient training (4.8%) to perform PR, as well as to plan the educational program for patients (10%) and the confidence to refer patients to PR (6.5%). This is the first study to evaluate the preparedness of professionals from the Brazilian public health network to provide PR. Notably, both PT and MT have low preparation to perform PR in the studied cities, reinforcing the need for continuing education.

RESUMO O déficit de conhecimento dos profissionais de saúde tem sido uma barreira para a expansão e implementação dos serviços de reabilitação pulmonar (RP), apesar dos seus benefícios comprovados para indivíduos com doença respiratória crônica (DRC). Objetivo: avaliar o preparo dos profissionais de saúde de dois municípios brasileiros para fornecer a RP no sistema público de saúde. Esse estudo, do tipo survey, foi parte de um projeto maior para implementação da RP no sistema público de saúde brasileiro. Foi utilizado um questionário autoaplicável para avaliar o conhecimento (19 questões), o treinamento (7 questões), a confiança (10 questões) e a experiência clínica (8 questões) dos fisioterapeutas (FT) e da equipe multiprofissional (EM), aplicado antes de um workshop sobre RP. No total, 44 FT e 231 EM responderam o questionário. A pontuação média de conhecimento foi de 10±3 para FT e 6±3 para EM. Poucos FT referiam ter “muita” experiência (25%) e confiança (22,7%) para realizar RP, bem como treinamento suficiente para realizar o teste de caminhada de seis minutos (27,3%). Ainda menos profissionais da EM relataram ter “muita” experiência (10%) e treinamento suficiente (4,8%) para realizar RP, assim como para planejar o programa educacional dos pacientes (10%) e ter confiança para encaminhar pacientes para a RP (6,5%). Este é o primeiro estudo a avaliar o preparo dos profissionais da rede pública de saúde no Brasil para fornecer RP. Notavelmente, tanto FT quanto EM têm baixo preparo para realizar RP nos municípios estudados, reforçando a necessidade de realização de educação continuada.

RESUMO Introdução: A qualidade da comunicação entre o profissional de saúde e o paciente é um importante pilar para uma atenção em saúde eficiente. O estado de Roraima caracteriza-se por possuir um alto percentual de indígenas, além de outros grupos que demandam linguagens de comunicação específicas. Objetivo: Este estudo teve como objetivo avaliar comparativamente os níveis de conhecimento dos estudantes do curso de Medicina e dos profissionais médicos recém-formados pela Universidade Federal de Roraima (UFRR) e dos discentes de outros cursos de graduação da UFRR, que não pertencem à área de saúde, acerca da Língua Brasileira de Sinais (Libras) e das línguas indígenas Macuxi, Yanomami e Wapichana. Método: Trata-se de um estudo de corte transversal, observacional e descritivo, com caráter quantitativo, envolvendo 202 participantes, o qual utilizou como ferramenta de coleta de dados um questionário estruturado aplicado de forma virtual. Resultado: O presente estudo envolveu 80 estudantes ou profissionais recém-formados em Medicina (39,6%), 47 estudantes ou profissionais recém-formados de Engenharia (23,3%) e 75 estudantes ou profissionais recém-formados de Direito (37,1%). Dentre a totalidade dos participantes, 100 eram homens (49,5%) e 102 mulheres (50,5%). Houve associação entre cursar Medicina e saber falar pelo menos uma língua indígena (p = 0,0004). Essa relação não foi evidenciada nos cursos de Direito e Engenharia Civil. Também foi identificada a associação entre estar cursando ou ter cursado Medicina e ter interesse em aprender Libras (p = 0,0159) ou ter interesse em aprender uma língua indígena (p = 0,0054). Essa associação não foi identificada entre os alunos que cursaram ou estavam cursando Direito ou Engenharia Civil. Conclusão: Apesar de os participantes de Medicina possuírem um maior nível de conhecimento a respeito de línguas indígenas e Libras, quando comparados aos outros cursos, isso não garante uma atenção em saúde efetiva em sua integralidade, uma vez que se evidenciou uma grande dificuldade no processo de comunicação entre eles com indígenas e pessoas surdas.

ABSTRACT Introduction: The quality of communication between the health professional and the patient is an important pillar for efficient health care. The state of Roraima is characterized by having a high percentage of indigenous individuals, in addition to other groups that demand specific communication languages. Objective: This study aimed to comparatively evaluate the levels of knowledge of Medical students and newly graduated medical professionals from Universidade Federal de Roraima (UFRR) and students from other undergraduate courses at UFRR, who do not belong to the health area, of the Brazilian Sign Language (LIBRAS, Língua Brasileira de Sinais) and the Macuxi, Yanomami and Wapichana indigenous languages. Method: This is a cross-sectional, observational and descriptive study, with a quantitative approach, involving 202 participants, which used a structured questionnaire applied virtually as the data collection tool. Results: The present study assessed 80 students or newly graduated doctors (39.6%), 47 engineering students or newly graduated ones (23.3%) and 75 Law students or newly graduated ones (37.1%). Of all participants, 100 were men (49.5%) and 102 were women (50.5%). There was an association between studying medicine and knowing how to speak at least one indigenous language (p = 0.0004). This relationship was not demonstrated for the Law and Civil engineering courses. An association was also identified between studying or having studied Medicine and being interested in learning LIBRAS (p = 0.0159) or being interested in learning an indigenous language (p = 0.0054). This association was not identified in students who studied or were studying Law or Civil engineering. Conclusion: Although medical participants have a higher level of knowledge about indigenous languages and LIBRAS when compared to the other courses, this does not guarantee effective health care in its entirety, since there was great difficulty related to the process of communication between them and indigenous and deaf individuals.

ABSTRACT Purpose: To evaluate, by quantitative and qualitative methods, the glomerular ultrastructure in Wistar rats fed a cafeteria diet. Methods: Male Wistar rats were divided into two groups at 21 days of age: control (C, n = 10) and cafeteria diet (CAF, n = 8). The animals were followed up until 5 months of age, followed by euthanasia. The blood, kidneys, and fat deposits––epididymal, retroperitoneal, and subcutaneous––were extracted and analyzed. Data were analyzed by Student’s t test, and p < 0.05 was considered statistically significant. Results: The cafeteria diet promoted glucose intolerance, hyperglycemia (p < 0.0001), and deposition of retroperitoneal fat (p < 0.005). Scanning electron microscopy revealed that the length of the foot process was similar in both groups. The quantitative analyses by transmission electron microscopy revealed that the cafeteria diet reduced the thickness of the glomerular basement membrane (p < 0.05). Conclusions: The intake of lipids and simple carbohydrates were found to be associated with alteration in the glomerular ultrastructure. However, more studies are needed to evaluate not only the effects of high-protein and high-fat diets on components of the glomerular filtration barrier, but also renal physiology.

BACKGROUND Monitoring and analysing the infection rates of the vector of Trypanosoma cruzi, that causes Chagas disease, helps assess the risk of transmission. OBJECTIVES A study was carried out on triatomine in the State of Paraná, Brazil, between 2012 and 2021 and a comparison was made with a previous study. This was done to assess the risk of disease transmission. METHODS Ecological niche models based on climate and landscape variables were developed to predict habitat suitability for the vectors as a proxy for risk of occurrence. FINDINGS A total of 1,750 specimens of triatomines were recorded, of which six species were identified. The overall infection rate was 22.7%. The areas with the highest risk transmission of T. cruzi are consistent with previous predictions in municipalities. New data shows that climate models are more accurate than landscape models. This is likely because climate suitability was higher in the previous period. MAIN CONCLUSION Regardless of uneven sampling and potential biases, risk remains high due to the wide presence of infected vectors and high environmental suitability for vector species throughout the state and, therefore, improvements in public policies aimed at wide dissemination of knowledge about the disease are recommended to ensure the State remains free of Chagas disease.

RESUMO As doenças periodontais necrosantes são condições historicamente estabelecidas e ganharam destaque no período da primeira guerra mundial, sua etiologia estava ligada a falta de higiene oral, infecções oportunistas e quadros de estresse. De caráter grave e debilitante, a doença progride rapidamente com úlceras necróticas em tecido periodontal, gerando dor, sangramento dos tecidos e odor fétido. Em virtude de suas características e da evolução acelerada dos quadros periodontais em pacientes imunocomprometidos, pacientes portadores do vírus da imunodeficiência humana que desenvolvem a síndrome da imunodeficiência adquirida são classificados como pacientes de risco para desenvolvimento de doenças periodontais necrosantes. Dessa forma, a presente revisão busca comparar a prevalência de gengivite e periodontite necrosante em pacientes com AIDS em relação a população imunocompetente, bem com avaliar como o estado de imunossupressão altera a cavidade bucal; esclarecer a respeito do impacto da AIDS nas doenças periodontais. O presente estudo foi conduzido seguindo os protocolos metodológicos da revisão sistemática descritos no Cochrane Handbook. A estratégia de busca foi aplicada nas bases de dados: Pubmed, Cochrane Library, Scopus, Web of Science e Embase.

ABSTRACT Necrotizing periodontal diseases are historically established conditions that gained prominence during the First World War. Their etiology was linked to poor oral hygiene, opportunistic infections, and stress. Characterized by severity and debilitation, the disease progresses rapidly with necrotic ulcers in periodontal tissues, resulting in pain, tissue bleeding, and a foul odor. Due to the distinctive features and accelerated evolution of periodontal conditions in immunocompromised patients, individuals with Human Immunodeficiency Virus leading to Acquired Immunodeficiency Syndrome are classified as at-risk patients for the development of Necrotizing periodontal diseases. Thus, this review aims to compare the prevalence of gingivitis and necrotizing periodontitis in AIDS patients in comparison to the immunocompetent population. Additionally, it seeks to evaluate how the state of immunosuppression alters the oral cavity and provides clarity regarding the impact of AIDS on periodontal diseases. This study adhered to the methodological protocols of a systematic review as outlined in the Cochrane Handbook. The search strategy was implemented across the following databases: Pubmed, Cochrane Library, Scopus, Web of Science, and Embase. The association of necrotizing periodontal diseases in HIV+ individuals was investigated through a systematic analysis of the literature.

Resumo Objetivo: Avaliar os resultados da instrumentação endodôntica e o tempo de preparo de lima odontopediátrica ativada por motor (Sequence Baby File- SBF) em canais de molares decíduos prototipados. Métodos: Trinta espécimes foram escaneados em micro-CT e divididos em três grupos de acordo com o tipo de instrumentação: mecanizada odontopediátrica (SBF); mecanizada convencional; lima K manual. O tempo de instrumentação foi cronometrado. Após o preparo, os espécimes foram escaneados novamente. As imagens pré e pós-instrumentação foram sobrepostas e a quantidade de desvio do canal radicular e a espessura de resina remanescente foram mensurados. Para as análises de comparações entre os grupos foram realizados teste ANOVA seguido do teste de Tukey (p<0,05). Resultados: Não ocorreram diferenças estatisticamente significativas entre os grupos no desvio do canal radicular (p>0,05). Houve diferenças estatisticamente significativas na comparação entre terços radiculares (p<0,001), mas sem diferenças significativas na interação grupo vs. terço radicular (p>0,05). A instrumentação mecanizada apresentou desgaste estatisticamente maior do que a instrumentação manual (p<0,001), sem diferenças estatísticas entre a SBF e a lima mecanizada convencional. A instrumentação mecanizada teve menor tempo de trabalho quando comparado a instrumentação manual (p<0,001). Conclusão: A instrumentação mecanizada odontopediátrica demonstrou bons resultados em relação ao desvio do canal radicular e quantidade de estrutura remanescente, com menor tempo de instrumentação. A SBF pode ser uma alternativa adequada para a instrumentação endodôntica em molares decíduos.

Abstract Evaluate the shaping ability and preparation time using a pediatric motor-driven rotary instrumentation compared to other systems in resin prototypes of primary molars. Methods: Thirty specimens were scanned in micro-CT and divided into three groups according to the instrumentation type: pediatric motor-driven Sequence baby File (SBF); conventional motor-driven (Sequence Rotary File - SRF); manual K file. Instrumentation time was timed. After preparation, the specimens were scanned again. The pre- and post-instrumentation images were superimposed to measure the amount of root canal deviation and the resin remnant thickness. ANOVA followed by the Tukey test analyzed the comparisons between groups (p<0.05). Results: No statistically significant differences occurred in root canal deviation among groups (p>0.05). There were statistically significant differences in the comparison among root thirds (p<0.001) but without significant differences in the interaction group vs. root third (p>0.05). Both motor-driven instrumentations showed statistically greater weariness than manual instrumentation (p<0.001), without significant significant differences between SBF and SRF. Motor-driven instrumentation had a shorter working time than manual instrumentation (p<0.001). Conclusion: Pediatric motor-driven instrumentation demonstrated good outcomes in relation to root canal deviation and amount of remnant structure, with shorter instrumentation time. SBF can be a suitable alternative for endodontic instrumentation in primary molars.

ABSTRACT Integrated agricultural production systems have been improved with the introduction of Urochloa grasses aiming at obtaining straw for a no-tillage system (NTS) and the increase of legumes, which promote physicochemical improvements in soils and guarantee intensification and sustainability of production. This study aimed to evaluate the agronomic traits and yield of soybean in succession to the intercropping of corn with marandu grass and/or pigeonpea in five populations of plants harvested for silage production. The experiment was carried out in the Cerrado region of Selvíria, MS, Brazil, during the 2016/17 and 2017/18 agricultural years, in an Oxisol. The experimental design consisted of randomized blocks, with four replications. The treatments were arranged in a 2×5 factorial scheme, consisting of off-season corn intercropped with pigeonpea (Cajanus cajan (L.) Millsp.) and off-season corn intercropped with marandu grass (Urochloa brizantha) and pigeonpea, in addition to five sowing densities (0, 6, 12, 18, and 24 seeds m-1). Soybean was planted in succession aiming to evaluate the effect of remaining straw on crop performance. Soybean grown in succession to the triple intercropping of corn with marandu and pigeon pea shows increased productivity.

Mari-mari (Cassia leiandra Benth.) is an Amazonian native fruit that is highly appreciated in the northern region of Brazil, but there are few studies regarding its chemical composition and/or biological properties. A phytochemical study was conducted on the extracts of the pulp, peel and seeds; and their antioxidant, cytotoxic and antimicrobial potential were also determined. Methanol and acetone extracts from different fruit parts were subjected to total phenolic, 2,2-diphenyl-1 picrylhydrazyl (DPPH) radical scavenging and FeIII reducing capacity (FRAP) assays. From the peel extracts, the engeletin and astilbin could also be isolated and characterized based on nuclear magnetic resonance spectroscopy and high-resolution mass spectrometry. A quantification using ultra-fast liquid chromatography of acetone dry crude extracts (DCE) of the peel showed that engeletin was the main compound (532.77 mg g-1 DCE). Astilbin content was also determined (131.53 mg g-1 DCE). The antibacterial and antiproliferative activities were evaluated and the methanol extract of the peel showed higher growth inhibition activity against all tested bacteria. Engeletin showed a relevant antimicrobial effect against Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli. Acetone and methanol peel extracts exhibited a relevant inhibitory effect on the proliferation of breast carcinoma cells (MCF-7), with no toxicity to the normal cell line (NIH/3T3).

ABSTRACT Objective: To describe adverse event following immunization or vaccination in children in Minas Gerais: 2015 to 2020, resulting from immunization errors in children from zero to nine years old. Methods: An ecological, descriptive study with a quantitative approach, based on event notifications available in the National Immunization Program Information System. Results: Among the 39,903,277 doses of immunobiologicals in children aged zero to nine, administered in the state of MG, 3,259 events of types of immunization errors were recorded, around 0.008% of the total and, of these, 91.86% did not result in adverse events and 56.02% were children under one year of age. The most frequent diagnosis was application outside the recommended age (29.12%). Among the manifestations, 71.91% were local and systemic, with fever being the most common (40.85%). Conclusion: The study demonstrated that immunization errors were rare and that most of them were not associated with adverse events, which reinforces the safety of the immunization process. This undoubtedly raises reflection on the need and relevance of continuing education for health professionals.

RESUMO Objetivo: Descrever os eventos supostamente atribuíveis à imunização ou vacinação em crianças de Minas Gerais, de 2015 a 2020, decorrentes dos erros de imunização em crianças de 0 a 9 anos. Métodos: Estudo ecológico, descritivo, de abordagem quantitativa, fundamentado nas notificações de eventos disponíveis no Sistema de Informações do Programa Nacional de Imunizações. Resultados: Dentre os 39.903.277 de doses de imunobiológicos administrados em crianças de 0 a 9 anos, no estado de Minas Gerais, registraram-se 3.259 eventos do tipo erros de imunizaçõo, cerca de 0,008% do total e, destes, 91,86% não acarretaram eventos adversos e 56,02% ocorreram em crianças menores de 1 ano. O diagnóstico mais frequente foi a aplicação fora da idade recomendada (29,12%). Dentre as manifestações, 71,91% foram locais e, em relação às sistêmicas, a mais comum foi a febre (40,85%). Conclusão: O estudo demonstrou que os erros de imunização foram raros e a maioria deles não se associou aos eventos adversos, o que reitera a segurança no processo de imunização. Isso suscita, indubitavelmente, a reflexão sobre a necessidade e a relevância de educação permanente dos profissionais da saúde.
