Abstract Introduction Provisional prostheses protect dental preparations during treatment, with conventional and digital methods available for fabrication. While 3D-printed resins show promise for durability and mechanical properties, further research is needed to clarify their advantages over conventional acrylic resins, specifically in terms of surface roughness, hardness, and resistance in provisional crowns. Objective To compare conventional acrylic resin and 3D printed resin for fabrication of provisional prostheses through an in vitro study on surface roughness, hardness, and mechanical resistance. Material and method Bars (25 x 12 x 2 mm) of heat-polymerized acrylic resin (RAT=05) and self-polymerized acrylic resin (RAA=05), as well as 3D printed resin (R3D=05), were fabricated for conducting tests on mean surface roughness (Ra), Vickers hardness, and three-point flexural strength. Subsequently, the specimens were evaluated after fracture. Surface characterization was also performed with significant specimens per experimental group (N=1) using a stereomicroscope, scanning electron microscope, and profilometer. Result Data on surface roughness, hardness, and mechanical resistance were subjected to one-way ANOVA (p < 0.05), followed by Tukey's test when a statistically significant difference was identified. Findings from surface analysis and fractography were presented qualitatively. The R3D group exhibited a surface with successive layers distinct from other resins. There was no statistical difference between groups for surface roughness (p=0.220). However, statistical differences were identified among experimental groups for hardness and mechanical resistance (p=0.000). Notably, the R3D group showed higher mean hardness (19.50 VD) and lower mean mechanical resistance (54.08 MPa). Specimens from the R3D group showed two or more fragments after fracture, whereas other groups exhibited only two fragments. Similarity was observed regarding surface roughness between conventional acrylic resins and 3D printed resin. Conclusion The 3D printed resin demonstrated both superior and inferior performance compared to conventional acrylic resins in terms of hardness and mechanical strength. treatment 3Dprinted Dprinted D properties crowns 25 (2 1 mm heatpolymerized heat polymerized RAT=05 RAT05 RAT 05 (RAT=05 selfpolymerized self RAA=05, RAA05 RAA RAA=05 , (RAA=05) R3D=05, R3D05 RD R3D=05 R (R3D=05) Ra, Ra (Ra) threepoint three point strength Subsequently fracture N=1 N1 N (N=1 stereomicroscope microscope profilometer oneway one way p 0.05, 005 0.05 0 0.05) Tukeys Tukey s qualitatively p=0.220. p0220 p=0.220 . 220 (p=0.220) However p=0.000. p0000 p=0.000 000 (p=0.000) Notably 19.50 1950 19 50 (19.5 VD 54.08 5408 54 08 (54.0 MPa.

Resumo Introdução Próteses provisórias protegem os preparos dentários durante o tratamento, com métodos convencionais e digitais disponíveis para sua fabricação. Embora as resinas impressas em 3D apresentem potencial para durabilidade e propriedades mecânicas, mais pesquisas são necessárias para esclarecer suas vantagens em relação às resinas acrílicas convencionais, especificamente quanto à rugosidade de superfície, dureza e resistência em coroas provisórias. Objetivo Comparar a resina acrílica convencional e a resina impressa 3D para confecção de próteses provisórias, através de um estudo in vitro sobre rugosidade superficial, dureza e resistência mecânica. Material e método Barras (25 x 12 x 2 mm) em resina acrílica termopolimerizável (RAT=05) e autopolimerizável (RAA=05), além de resina Impressa 3D (R3D=05) foram confeccionadas para a realização dos testes de rugosidade superficial média (Ra), Dureza Vickers e resistência à flexão três pontos, em seguida os espécimes foram avaliados após a fratura. Também foi realizada a caracterização superficial com espécimes significativos por grupo experimental (N=1), por meio de estereomicroscópio, microscópio eletrônico de varredura e perfilômetro. Resultado Os dados de rugosidade superficial, dureza e resistência mecânica foram submetidos ao teste estatístico ANOVA 1 Fator (p < 0,05), seguido pelo Teste de Tukey quando tenha sido identificada diferença estatisticamente significativa. Os achados da análise superficial e da fractografia foram apresentados de forma qualitativa. O grupo R3D apresentou uma superfície com camadas sucessivas e distinta das demais resinas. Não houve diferença estatística entre grupos para a rugosidade superficial (p=0,220). Para dureza e resistência mecânica (p=0,000) foi identificada diferença estatística entre grupos experimentais. Destacando o grupo R3D com maior média de dureza (19,50 VD) e menor média de resistência mecânica (54,08 Mpa). Os espécimes do grupo R3D apresentam dois ou mais fragmentos após a fratura, já nos demais grupos havia apenas dois fragmentos. Identificou-se semelhança quanto à rugosidade superficial entre as resinas acrílicas convencionais e a resina impressa 3D. Conclusão A resina impressa 3D apresentou desempenho superior e inferior, quando comparada com as resinas acrílicas convencionais, em relação a dureza e a resistência mecânica. tratamento fabricação D mecânicas 25 (2 mm RAT=05 RAT05 RAT 05 (RAT=05 RAA=05, RAA05 RAA RAA=05 , (RAA=05) R3D=05 R3D05 RD R (R3D=05 Ra, Ra (Ra) pontos fratura N=1, N1 N N=1 (N=1) estereomicroscópio perfilômetro p 0,05, 005 0,05 0 0,05) significativa qualitativa p=0,220. p0220 p=0,220 . 220 (p=0,220) p=0,000 p0000 000 (p=0,000 experimentais 19,50 1950 19 50 (19,5 VD 54,08 5408 54 08 (54,0 Mpa.

ABSTRACT This study aims to assess COVID-19 and other respiratory viruses in pediatric patients. Between April 17 and September 30, 2020, we collected 1,566 respiratory samples from 1,044 symptomatic patients who were younger than 18 years old to assess SARS-CoV-2 infection. Of these, 919 were analyzed for other respiratory pathogens (ORP). Patients with laboratory-confirmed COVID-19 or ORP were included. We evaluated 76 pediatric COVID-19 infections and 157 other respiratory virus infections. Rhinovirus occurred in 132/157 (84%). COVID-19 patients who were significantly older, had more fevers, headaches and pneumonia than those with ORP. The median white blood cell count was lower in patients with SARS-CoV-2 than in those with ORP (6,470 versus 8,170; p=0.02). COVID-19 patients had significantly worse symptoms than those with ORP.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

OBJECTIVES: To assess the outcomes of pediatric patients with laboratory-confirmed coronavirus disease (COVID-19) with or without multisystem inflammatory syndrome in children (MIS-C). METHODS: This cross-sectional study included 471 samples collected from 371 patients (age<18 years) suspected of having severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study group comprised 66/371 (18%) laboratory-confirmed pediatric COVID-19 patients: 61 (92.5%) patients tested positive on real-time reverse transcription-polymerase chain reaction tests for SARS-CoV-2, and 5 (7.5%) patients tested positive on serological tests. MIS-C was diagnosed according to the criteria of the Center for Disease Control. RESULTS: MIS-C was diagnosed in 6/66 (9%) patients. The frequencies of diarrhea, vomiting, and/or abdominal pain (67% vs. 22%, p=0.034); pediatric SARS (67% vs. 13%, p=0.008); hypoxemia (83% vs. 23%, p=0.006); and arterial hypotension (50% vs. 3%, p=0.004) were significantly higher in patients with MIS-C than in those without MIS-C. The frequencies of C-reactive protein levels >50 mg/L (83% vs. 25%, p=0.008) and D-dimer levels >1000 ng/mL (100% vs. 40%, p=0.007) and the median D-dimer, troponin T, and ferritin levels (p<0.05) were significantly higher in patients with MIS-C. The frequencies of pediatric intensive care unit admission (100% vs. 60%, p=0.003), mechanical ventilation (83% vs. 7%, p<0.001), vasoactive agent use (83% vs. 3%, p<0.001), shock (83% vs. 5%, p<0.001), cardiac abnormalities (100% vs. 2%, p<0.001), and death (67% vs. 3%, p<0.001) were also significantly higher in patients with MIS-C. Similarly, the frequencies of oxygen therapy (100% vs. 33%, p=0.003), intravenous immunoglobulin therapy (67% vs. 2%, p<0.001), aspirin therapy (50% vs. 0%, p<0.001), and current acute renal replacement therapy (50% vs. 2%, p=0.002) were also significantly higher in patients with MIS-C. Logistic regression analysis showed that the presence of MIS-C was significantly associated with gastrointestinal manifestations [odds ratio (OR)=10.98; 95%CI (95% confidence interval)=1.20-100.86; p=0.034] and hypoxemia [OR=16.85; 95%CI=1.34-211.80; p=0.029]. Further univariate analysis showed a positive association between MIS-C and death [OR=58.00; 95%CI=6.39-526.79; p<0.0001]. CONCLUSIONS: Pediatric patients with laboratory-confirmed COVID-19 with MIS-C had a severe clinical spectrum with a high mortality rate. Our study emphasizes the importance of investigating MIS-C in pediatric patients with COVID-19 presenting with gastrointestinal involvement and hypoxemia.

OBJETIVO: estimar a prevalência das formas de violência contra crianças e adolescentes, registradas nos Conselhos Tutelares, e a associação dessas violências por faixas etárias das vítimas e vínculo com agressores, em 2003-2004. MÉTODO: foram coletados dados dos prontuários e calculadas as prevalências e associação entre variáveis, através da razão de prevalência (RP), com nível crítico de 5%. RESULTADOS: totalizaram 1.293 registros de violência, sendo 1.011 (78,1%) originados no domicílio. As violências mais freqüentes foram a negligência (727), por omissão de cuidados básicos (304) e abandono (259); a violência física (455), por espancamento (392), nas faixas de 2 a 13 anos; a violência psicológica (374), por amedrontamento (219); a violência sexual (68), por abuso (58), principalmente entre adolescentes. A principal forma de denúncia foi anônima, 398 (30,8%); os agressores para negligência foram os pais; para violência física, a madrasta e "outros agressores"; para violência sexual, o padrasto, "outros familiares/ agressores"; a violência psicológica foi prevalente entre todas categorias de agressores. CONCLUSÕES: Os resultados apontam para a necessidade de divulgação do "Disque Denúncia"; a formação de conselheiros, quanto ao registro adequado, assim como a implementação de políticas de prevenção da violência contra crianças e adolescentes.

OBJECTIVE: To estimate the prevalence of violence against children and adolescents through the records of Child Protection Councils, associating this violence with the age of the victims and their links with the aggressor. METHOD: Data were collected from the records and the prevalence rates were calculated through the Prevalence Ratio (PR), together with the associations among variables, with a critical level of 5%. RESULTS: Out of 1,293 records of violence, 1,011 (78.1%), originated in the home. The most frequent types of violence were: neglect (727), failure to provide basic care (304) and abandonment (259); physical violence (455), beatings (392) between 2 and 13 years old; psychological violence (374) through threats (219); sexual violence (68) through abuse (58), mainly among adolescents. Denunciations were mainly (398) anonymous (30.8%); the aggressors through neglect were the parents; through physical violence, the stepmother and "other aggressors"; through sexual violence, the stepfather and "other relatives / aggressors"; psychological violence was prevalent among all aggressor categories. CONCLUSIONS: The findings indicate the need to extend the Anti-Violence Hot-line facilities, training Council Members in terms of keeping proper records, and implementing policies designed to prevent violence against children and adolescents.

OBJETIVO: analisar o uso de bebidas alcoólicas, cigarros, outras substâncias psicoativas - SPA e fatores de risco entre adolescentes das escolas de um município com 500 mil/hab., Bahia/Brasil. MÉTODO: estudo transversal, com amostra aleatória, estratificada por conglomerado com adolescentes de 14 a 19 anos, totalizando 10 escolas públicas e 1.409 alunos de Feira de Santana. O instrumento auto-aplicável foi elaborado segundo a OMS e outros estudos nacionais adequados à faixa adolescente, com rigoroso procedimento, garantindo anonimato e sigilo. RESULTADOS: 86,5% dos adolescentes consideravam-se bem informados sobre SPA, a maioria por TV, rádio e escola; 57,0% relataram uso de bebidas alcoólicas, principalmente cervejas e vinhos; 23,3% usavam cigarros e 5,2% outras SPA (cânabis, solventes e cocaína); 29,3% usavam bebidas uma a três vezes/mês e 13% todo final de semana. Na faixa de 10 a 14 anos, 47% experimentaram bebidas e 16,7% outras SPA. A razão de prevalência (RP) mostrou consumo de bebidas, cigarros e outras SPA significantemente maiores na faixa 17 a 19 anos e sexo masculino. A curiosidade foi a principal motivação; na companhia de amigos e pais; festas e casas de colegas. CONCLUSÕES: A Necessidade de institucionalização de atividades adequadas nas escolas à prevenção do uso das SPA entre jovens.

O presente estudo buscou identificar e descrever as ações dos senadores brasileiros, na área de saúde pública, no período de 1995 a 1996. Pretendeu-se também identificar a influência da profissão, região de origem e partido político sobre a atuação dos senadores. As ações foram divididas em três grupos: legislativas (proposição e apreciação de projetos de lei, pareceres e requerimentos), fiscalizadoras (requerimentos de informação ao Executivo e implementação de comissões parlamentares de inquérito e especiais) e parlamentares (discursos). O levantamento dos dados foi realizado em duas bases de dados mantidas pelo Senado Federal: MATE e DISC. Dos 89 parlamentares que exerceram mandato no período do estudo, 76 se envolveram com matérias de saúde. Foram estudadas 667 ações. Predominaram os discursos (43% das ações), em sua maioria respondendo a notícias veiculadas pelos meios de comunicação. Do total de ações, 60% envolveram políticas públicas (30%), drogas (9%), regulamentação das profissões de saúde (8%), controle de doenças (7%) e saúde do trabalhador (6%). A atividade fiscalizadora foi limitada (5% das ações foram requerimentos de informação). Em relação ao perfil dos senadores, predominaram os médicos, professores e jornalistas. Os parlamentares das Regiões Norte e Nordeste realizaram 62% de todas as ações e atuaram em relação a quase todos os temas. Os senadores de orientação liberal e de direita responderam por 43% de todas as ações; contudo, os de orientação socialista e trabalhista apresentaram maior participação proporcional (em termos de senadores envolvidos e de ações realizadas). É interessante notar que os senadores socialistas e trabalhistas não se envolveram com o tema "saúde do trabalhador". A predominância de discursos como ação, a proposição legislativa pontual e descontínua e, especialmente, a incipiente ação fiscalizadora, indicam a necessidade de reformular a sistemática de trabalho no âmbito das comissões técnicas e da consultoria técnica do Senado.

The objective of this study was to identify and describe the actions of Brazilian senators in the field of public health in 1995 and 1996. We also sought to determine if profession, regional background, or political party influenced the senators' actions. The actions were divided into three types: legislative (proposal and review of bills and petitions); supervisory (information requests to the executive branch and the establishment of inquiry committees and other special committees); and parliamentary (speeches). The data were collected from two databases maintained by the Senate, namely MATE and DISC. Of the 89 senators who were in office during the study period, 76 were involved with public health issues. Of the total of 667 actions studied, there was a predominance of speeches (43% of all actions), most of them responding to news reported by regional or national media. Supervisory activities were limited (5% of all actions were information requests). The subjects dealt with most frequently were health policies (30%), drugs (9%), regulation of health professions (8%), disease control (7%), and worker health (6%). Concerning the professions of the senators, the most frequent categories were physicians, teachers, and journalists. The senators representing the North and Northeast regions performed 62% of the actions and were involved with almost all the health subjects. Although 43% of the actions were carried out by liberal and right-wing senators, the senators from socialist and labor parties had a stronger proportional participation (both in terms of senators involved and actions performed). It is interesting to note that socialist and labor senators showed minimal involvement in the issue of worker health. The predominance of speeches as a prevalent type of action, the limited and disjointed scope of legislative actions, and, especially, the poor monitoring and control show the need for deep changes in the work process of the Senate's technical committees and, therefore, of the Senate's technical support unit.
