ABSTRACT

Abstract Objective The present study aims to highlight the significance of the nucleic acid test (NAT) for musculoskeletal tissue donation and to compare the sensitivity of this test on the different available platforms. Method The present study is a retrospective survey in a human tissue bank database and an integrative literature review encompassing the last 10 years. The PubMed portal and the SCOPUS, CINAHL, and Web of Science databases were queried for articles. Results We found no specific studies on the use and sensitivity of NAT in braindead tissue donors. The information presented in the present study consists of specific contents intended for the Brazilian Blood Transfusion Network (Hemorrede Transfusional Nacional, in Portuguese) and internal retrospective data from a tissue bank located at a city in the state of São Paulo, Brazil. Conclusions The NAT is effective in blood samples from living patients. However, since biochemical reactions in braindead patients can be different, specific research, platforms, or both are crucial to tissue banks.


Resumo Objetivo Evidenciar a importância da realização do teste de ácido nucleico (NAT, na sigla em inglês) para doação de tecidos musculoesqueléticos, assim como comparar a sensibilidade deste exame nas diferentes plataformas existentes no mercado. Método Trata-se de um levantamento retrospectivo no banco de dados de um determinado Banco de Tecidos Humanos e de uma revisão integrativa da literatura, operacionalizada nos últimos 10 anos. As buscas de artigos ocorreram no portal PubMed e nas bases de dados SCOPUS, CINAHL e Web of Science. Resultados Não foram encontrados estudos específicos sobre a utilização e a sensibilidade do exame NAT em pacientes doadores de tecidos com morte encefálica (ME), sendo as informações apresentadas no presente estudo conteúdos específicos destinados à Hemorrede Transfusional Nacional e aos dados retrospectivos internos de um Banco de Tecidos do interior do estado de São Paulo, Brasil. Conclusões O exame NAT se apresenta efetivo em amostras de sangue de pacientes vivos. Porém, reações bioquímicas em pacientes com condições de ME podem se apresentar de formas diferenciadas, tornando-se indispensáveis a realização de pesquisas específicas e/ou a indicação de plataformas aos Bancos de Tecidos.

ABSTRACT

Resumo Durante a pandemia da Covid-19, o serviço para tratamento do fumante foi impactado. Este artigo avaliou o impacto da pandemia sobre o serviço no SUS. Trata-se de um estudo observacional descritivo ecológico utilizando o banco de dados do Programa Nacional de Controle do Tabagismo (PNCT) anos 2019, 2020 e 2021, de cinco estados (PA, PB, GO, RJ e RS) referente ao segundo quadrimestre. Foram estimadas as diferenças relativas no número de unidades que ofereceram o serviço e no número de atendimentos para avaliação clínica, primeira e quarta sessões. Para os anos de 2019 e 2020, observou-se diferença percentual no número de unidades que ofereceram o serviço em todos os estados estudados de -51,9%. Para os anos de 2019 e 2021, a diferença relativa para as unidades de saúde foi de -20,96% e, para a avaliação clínica, primeira e quarta sessões foram: -54,19%, -55,07% e -61,31%, respectivamente. Essas diferenças foram maiores para as capitais quando comparadas com os demais municípios. Apesar do impacto negativo, principalmente no primeiro ano da pandemia, o estudo mostrou que os serviços não interromperam suas atividades e mostraram alguma recuperação em 2021.Também foi importante observar que os tabagistas, apesar das recomendações, não deixaram de procurar o tratamento.


Abstract During the Covid-19 pandemic, the smoker treatment service was impacted. This article evaluated the impact of the pandemic on the service in the SUS. This is an ecological descriptive observational study using the National Tobacco Control Program (PNCT) database for the years 2019, 2020 and 2021, from five states (PA, PB, GO, RJ and RS) for the second four months. Relative differences were estimated in the number of units that offered the service and in the number of consultations for clinical evaluation, first and fourth sessions. For the years 2019 and 2020, there was a percentage difference of -51.9% in the number of units that offered the service in all states studied. For the years 2019 and 2021, the relative difference for the health units was -20.96% and, for the clinical evaluation, the first and fourth sessions were: -54.19%, -55.07% and -61 .31%, respectively. These differences were greater for the capitals when compared to the other municipalities. Despite the negative impact, especially in the first year of the pandemic, the study showed that the services did not interrupt their activities and showed some recovery in 2021. It was also important to note that smokers, despite the recommendations, did not stop seeking treatment.

ABSTRACT

Abstract Objective Similar to Human Papillomavirus (HPV) genotypes, different lineages of a genotype also have different carcinogenic capabilities. Studies have shown that specific genotype lineages of oncogenic HPV are associated with variable risks for the development of cervical intraepithelial neoplasia (CIN2/CIN3) and cervical cancer. The present study aimed to analyze the genetic diversity of the HPV16 genotype in women with CIN2/CIN3 and cervical cancer, from the northeast region of Brazil. Methods A cross-sectional multicenter study was conducted in the northeast region of Brazil, from 2014 to 2016. This study included 196 cases of HPV16 variants (59 and 137 cases of CIN2/CIN3 and cervical cancer, respectively). The difference of proportion test was used to compare patients with CIN2/CIN3 and cervical cancer, based on the prevalent HPV16 lineage (p < 0.05). Results According to the histopathological diagnosis, the percentage of lineage frequencies revealed a marginal difference in the prevalence of lineage A in CIN2/CIN3, compared with that in cervical cancer (p = 0.053). For lineage D, the proportion was higher in cancer cases (32.8%), than in CIN2/CIN3 cases (16.9%), with p = 0.023. Conclusion HPV16 lineage A was the most frequent lineage in both CIN2/CIN3 and cervical cancer samples, while lineage D was predominant in cervical cancer, suggesting a possible association between HPV16 lineage D and cervical cancer.


Resumo Objetivo Tanto os tipos quanto as linhagens do Papilomavírus Humano (HPV) parecem ter diferentes capacidades carcinogênicas e estão associados a riscos variados para o desenvolvimento de neoplasia intraepitelial cervical (NIC) e câncer de colo do útero. O presente estudo tem como objetivo analisar a diversidade genética do genótipo HPV 16 nos casos de NIC2/NIC3 e câncer de colo de útero em mulheres da região Nordeste do Brasil. Métodos Estudo transversal de base hospitalar realizado na região Nordeste do Brasil no período de 2014 a 2016. A amostra foi composta por 196 casos da variante HPV-16 (59 casos de NIC2/NIC3 e 137 de câncer do colo do útero). O teste de diferença de proporção foi usado para comparar os grupos NIC2/NIC3 e câncer de colo do útero por linhagem viral em relação à prevalência da linhagem HPV-16. Foi considerada significância estatística o valor de p < 0,05. Resultados As frequências de linhagem por diagnóstico histopatológico mostraram diferença limítrofe da linhagem A no grupo NIC2/NIC3 em relação ao grupo câncer de colo de útero (p = 0,053). Por outro lado, em relação à linhagem D, houve uma proporção maior nos casos de câncer (32,8%) quando comparado ao grupo NIC2/NIC3 (16,9%) e esta diferença se mostrou estatisticamente significante (p = 0,023). Conclusão A linhagem A do HPV-16 foi a mais frequente tanto nas amostras CIN2/CIN3 quanto nas amostras de câncer de colo de útero, enquanto a linhagem D predominou no câncer de colo do útero, sugerindo uma possível associação da linhagem D de HPV-16 com câncer de colo de útero.

ABSTRACT

ABSTRACT Objective To analyze the relationship between internet search volume and the prevalence of waterpipe use among young Brazilians in 2019. Methods This was a descriptive study with data from Brazil in 2019, using the relative search volume on waterpipes extracted from Google Trends and the proportion of waterpipe users aged between 15 and 24 years, as measured by the National Health Survey (Pesquisa Nacional de Saúde - PNS), and aged between 13 and 17 years, as measured by the National Adolescent School-based Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE). The relationship was assessed by means of Spearman's correlation. Results The point prevalence of waterpipe use across the Brazilian Federative Units (FUs) showed a moderate (r = 0.51; PNS) to strong correlation (r = 0.74 and r = 0.80; PeNSE) with the relative search volume (p-value < 0.05). Conclusion Google Trends can support the monitoring system on waterpipe use in the FUs, providing additional information to existing population-based surveys.

ABSTRACT

The objective of this study was to evaluate the effect of abrasion wear on surface roughness and microhardness of different commercially available resin composites simulating pH-challenges of the oral cavity. Methods: Three resin composites (RC) were used in this study: one conventional: Z250; and two bulk fill resin composites (BRC): Tetric N-Ceram (TNC) and Sonic Fill (SF). The RC was inserted in a prefabricated mold (15mm wide x 4mm thickness) in two layers, or in a single layer for BRC. Thirty samples were prepared and surface roughness (Ra) and Knoop microhardness (KHN) test were performed at three different time-points of evaluation: baseline (24h after sample preparation); partial (after pH cycling); and final (after simulated toothbrushing procedure). Two samples of each group were selected after different treatments and analyzed descriptively on a scanning electron microscopy (SEM). Data from Ra and KHN were analyzed by two-way repeated-measures ANOVA and Bonferroni's post-hoc test with a significance level set at 5%. Results: Ra increased for all groups (p<0.001), at the final time-point, Z250 and TNC groups present the highest values. Oppositely, KHN decreased for all groups (p<0.001), Z250 group showed the highest KHN values for all time-points (p<0.001). The SEM imagens showed a regular surface for samples cycled and irregular with inorganic particles exposed for samples toothbrushed. Conclusion: pH-cycling and simulated toothbrushing affected the superficial properties (roughness and Knoop microhardness), as observed at SEM imagens, with irregular surface with inorganic particles exposure

ABSTRACT

Abstract To evaluate the feasibility of using a milled polyetheretherketone (PEEK) post and core in endodontically treated teeth with or without a ferrule. Sixty bovine tooth roots were endodontically treated followed by cementation of intraradicular retainers (IR), according to each experimental group: a) non-ferrule glass fiber post (f0FP); b) 2-mm-ferrule glass fiber post (f2FP); c) non-ferrule resized glass fiber post (f0PR); d) 2-mm-ferrule resized glass fiber post (f2PR); e) non-ferrule PEEK post and core (f0PPC); and f) 2-mm-ferrule PEEK post and core (f2PPC). Metal crowns were made and cemented. A periodontal ligament was simulated using polyether. A force was applied to the palatine portion of each sample at 45°, until fracture. Fracture resistance data were submitted to two-way ANOVA and Tukey's test (α = 0.05). Three-dimensional digital models were developed to calculate the tensions formed in the root using finite element analysis. Models of glass fiber posts and PEEK posts and cores were evaluated with or without a ferrule. The results were analyzed by the Mohr-Coulomb criterion. The type of IR was not influenced by fracture strength (p = 0.243). There were significant statistical differences among the remaining factors. Ferrule groups had greater fracture resistance, and the failure mode of teeth with a ferrule was more catastrophic than the non-ferrule group. A ferrule increases fracture resistance and influences failure mode; the PEEK post and core did not modify the biomechanics of endodontically treated teeth, and resembled the glass fiber post results. The crack initiation point differed between the ferrule and non-ferrule groups.

ABSTRACT

O câncer é um problema de saúde pública mundial. Na última década, houve um aumento de 20% na incidência e espera-se que, para 2030, ocorram mais de 25 milhões de casos novos. Estimativas do número de casos novos de câncer são uma ferramenta poderosa para fundamentar políticas públicas e alocação racional de recursos para o combate ao câncer. A vigilância do câncer é um elemento crucial para planejamento, monitoramento e avaliação das ações de controle do câncer. Objetivo: Estimar e descrever a incidência de câncer no país, Regiões geográficas, Unidades da Federação, Distrito Federal e capitais, por sexo, para o triênio 2023-2025. Método: As informações foram extraídas do Sistema de Informação sobre Mortalidade e dos Registros de Câncer de Base Populacional. Foram estimados os casos novos e suas respectivas taxas de incidência pelos modelos de predição tempo-linear ou pela razão de incidência e mortalidade. Resultados: São esperados 704 mil casos novos de câncer para o triênio 2023-2025. Excetuando o câncer de pele não melanoma, ocorrerão 483 mil casos novos. O câncer de mama feminina e o de próstata foram os mais incidentes com 73 mil e 71 mil casos novos, respectivamente. Em seguida, o câncer de cólon e reto (45 mil), pulmão (32 mil), estômago (21 mil) e o câncer do colo do útero (17 mil). Conclusão: No Brasil, por suas dimensões continentais e heterogeneidade, em termos de território e população, o perfil da incidência reflete a diversidade das Regiões geográficas, coexistindo padrões semelhantes ao de países desenvolvidos e em desenvolvimento


Cancer is a worldwide public health problem, in the last decade there was an increase of 20% of the incidence and more than 25 million new cases are expected by 2030. Estimates of the number of new cancer cases are a powerful tool to support public policies and rational allocation of resources to fight cancer. Cancer surveillance is paramount for planning, monitoring and evaluating cancer control programs. Objective: To estimate and to describe the incidence of cancer in the country, geographic regions, states, Federal District and capitals, by sex, for the 2023-2025 period. Method: Cancer mortality and incidence information were extracted from the Mortality Information System and from Population-Based Cancer Registries. The number of new cases and their respective incidence rates were estimated by time-linear prediction models or by the incidence and mortality ratio. Results: 704,000 new cases of cancer are expected for the triennium 2023-2025. Except for nonmelanoma skin cancer, 483,000 new cases will occur. Female breast cancer and prostate cancer were the most frequent with 73,000 and 71,000 new cases, respectively, followed by colorectal cancer (45,000), lung (32,000) and stomach (21,000), and cervical cancer (17,000). Conclusion: In Brazil, due to its continental dimensions and heterogeneity both in terms of population and territory, the incidence profile reflects the diversity of geographic regions, and patterns similar to developed and developing countries.

ABSTRACT

Abstract Studies have consistently shown a significant increase in the risk of congenital heart defects in the offspring of diabetic mothers compared with those of nondiabetic pregnancies. Evidence points that all types of pregestational diabetes have the capacity of generating cardiac malformations in a more accentuated manner than in gestational diabetes, and there seems to be an increased risk for all congenital heart defects phenotypes in the presence of maternal diabetes. Currently, the application of some therapies is under study in an attempt to reduce the risks inherent to diabetic pregnancies; however, it has not yet been possible to fully prove their effectiveness. The present review aims to better understand the mechanisms that govern the association between pregestational diabetes and congenital heart defects and how maternal diabetes interferes with fetal cardiac development, as there is still a long way to go in the investigation of this complex process.


Resumo Estudos têm demonstrado consistentemente um aumento significativo no risco de defeitos cardíacos congênitos em filhos de mães diabéticas em comparação com os de gestações não diabéticas. Evidências apontam que todos os tipos de diabetes pré-gestacional têm capacidade de gerar malformações cardíacas mais acentuadas do que no diabetes gestacional e parece haver um risco aumentado para todos os fenótipos de cardiopatias congênitas na presença de diabetes materno. Atualmente, está em estudo a aplicação de algumas terapias na tentativa de diminuir os riscos inerentes à gravidez diabética; no entanto, ainda não foi possível comprovar totalmente a sua eficácia. A presente revisão visa compreender melhor os mecanismos que regem a associação entre diabetes pré-gestacional e cardiopatias congênitas e como o diabetes materno interfere no desenvolvimento cardíaco fetal, pois ainda há um longo caminho a percorrer na investigação deste processo complexo.

ABSTRACT

Abstract Objective To provide a survey of relevant literature on umbilical artery Doppler ultrasound use in clinical practice, technical considerations and limitations, and future perspectives. Methods Literature searches were conducted in PubMed and Medline, restricted to articles written in English. Additionally, the references of all analyzed studies were searched to obtain necessary information. Results The use of this technique as a routine surveillance method is only recommended for high-risk pregnancies with impaired placentation. Meta-analyses of randomized trials have established that obstetric management guided by umbilical artery Doppler findings can improve perinatal mortality and morbidity. The values of the indices of Umbilical artery Doppler decrease with advancing gestational age; however, a lack of consensus on reference ranges prevails. Conclusion Important clinical decisions are based on the information obtained with umbilical artery Doppler ultrasound. Future efforts in research are imperative to overcome the current limitations of the technique.

ABSTRACT

This research aimed to evaluate the bond strength by micro tensile strength (µTBS), elastic modulus (EM) and flexural strength (FS) by the three-point test using three types of composite resins: Charisma Diamond, Filtek Z350 and Tetric N-Ceram Bulk Fill; and three adhesion techniques: adhesive, silane, silane and adhesive. The combinations of each resin with the adhesive technique resulted in nine groups (n = 12). Initially, with the composites, EM and FS tests were performed. Sequentially, each fragment was repaired with the different adhesive systems. All samples were subjected to µTBS testing on a universal assay machine. Data were subjected to the normality test and the parametric ANOVA test. Charisma resin showed the highest values in EM and RF compared to the other composite resins (p <0.05). The highest µTBS value was for silane + adhesive repaired Charisma resin. The lowest µTBS values were in Bulk Fill resin, regardless of adhesive system. The EM and FS results showed that Filtek Z350 resins had the best results, while bulk fill resins had lower results. It was concluded that Charisma and Filtek Z350 resins presented better results. However, in the bulk fill group, the lowest mean values of µTBS, FS and EM were obtained, as well as the lowest value in EM. (AU)


Esta pesquisa teve como objetivo avaliar a resistência de união (RU) por resistência à microtração, módulo de elasticidade (ME) e resistência à flexão (RF) pelo teste de três pontos, utilizando três tipos de resinas compostas: Charisma Diamond, Filtek Z350 e Tetric N-Ceram Bulk Fill; e três técnicas de adesão: adesivo, silano, silano e adesivo. As combinações de cada resina com a técnica adesiva resultaram nove grupos (n = 12). Inicialmente, com os compósitos foram realizados testes de ME e RF. Sequencialmente, cada fragmento foi reparado com os diferentes sistemas adesivos. Todas as amostras foram submetidas ao teste de RU por microtração em uma máquina de ensaio universal. Os dados foram submetidos ao teste de normalidade e ao teste paramétrico ANOVA. A resina Charisma apresentou os maiores valores no ME e RF em relação às demais resinas compostas (p <0,05). O maior valor de RU foi para a resina Charisma reparada com silano + adesivo. Os menores valores de RU foram na resina Bulk Fill, independentemente do sistema adesivo. Os resultados no ME e RF mostraram que as resinas Filtek Z350 obtiveram os melhores resultados, enquanto as resinas bulk fill obtiveram resultados inferiores. Conclui-se que as resinas Charisma e Filtek Z350 apresentaram melhores resultados. Entretanto, no grupo de bulk fill obteve-se as menores médias de RU, RF e ME, bem como o menor valor no ME. (AU)

ABSTRACT

Resumo: O comércio ilícito de produtos de tabaco, ao possibilitar acesso a cigarros mais baratos, favorece a iniciação do tabagismo e dificulta sua cessação, minimizando os efeitos da política de preços e impostos sobre a redução da demanda por tabaco, sobretudo entre populações de menor renda e escolaridade, onde se concentra o tabagismo. Seu enfrentamento requer ações multissetoriais, alinhadas à Convenção-Quadro para o Controle do Tabaco da Organização Mundial da Saúde e seus protocolos, e respaldadas em estimativas de sua magnitude e na análise de suas características. O estudo pretende analisar, por meio de amostras de resíduos sólidos domiciliares coletados em 2018 no Município do Rio de Janeiro, Brasil, a conformidade das embalagens de cigarros descartadas com critérios para a sua comercialização regular no país, classificando-as como legais ou ilegais. A avaliação foi feita também para as 15 Áreas de Planejamento (AP) do município. Escolheu-se o Índice de Desenvolvimento Social (IDS) para representar as heterogeneidades entre as AP. O percentual médio de embalagens de cigarros ilegais encontrado foi de 26,79%, variando de 3,36% a 46,29% entre as AP. As AP com alta ilegalidade apresentavam menores IDS e menores percentuais de embalagens de cigarros legais com preço igual ou superior a R$ 7,25. Dentre as embalagens ilegais, 98,07% apresentavam o Paraguai como país fabricante. O estudo contribui metodologicamente para dimensionar o consumo de cigarros ilegais na segunda capital econômica do Brasil, subsidiando a Política Nacional de Controle do Tabaco no combate ao comércio ilícito de produtos de tabaco e na efetiva implementação da política de preços e impostos sobre estes produtos.


Resumen: El comercio ilícito de productos del tabaco, al posibilitar el acceso a cigarrillos más baratos, favorece la iniciación del tabaquismo y dificulta la interrupción de su consumo, minimizando los efectos de la política de precios e impuestos sobre la reducción de la demanda de tabaco, sobre todo entre poblaciones de menor renta y escolaridad, donde se concentra el tabaquismo. Su combate requiere acciones multisectoriales, alineadas con la Convención-Marco para el Control del Tabaco de la Organización Mundia de la Salud, y sus protocolos, y respaldadas en estimaciones de su magnitud y en el análisis de sus características. El estudio pretende analizar, mediante muestras de residuos sólidos domiciliarios, recogidos en 2018 en el Municipio de Rio de Janeiro, Brasil, la conformidad de los paquetes de cigarrillos tirados a la basura con criterios para su comercialización regular en el país, clasificándolos como legales o ilegales. La evaluación se realizó también para las 15 Áreas de Planificación (AP) del municipio. Se escogió el Índice de Desarrollo Social (IDS) para representar heterogeneidades entre las AP. El porcentaje medio de paquetes de cigarrillos ilegales encontrado fue de un 26,79%, variando de 3,36% a 46,29% entre las AP. Las AP con alta ilegalidad presentaban menores IDS y menores porcentajes de paquetes de cigarrillos legales con un precio igual o superior a BRL 7,25. Entre los embalajes ilegales, un 98,07% presentaban Paraguay como el país fabricante. El estudio contribuye metodológicamente para dimensionar el consumo de cigarrillos ilegales en la segunda capital económica de Brasil, apoyando la Política Nacional de Control del Tabaco en el combate al comercio ilícito de productos del tabaco y en la efectiva implementación de la política de precios e impuestos sobre estos productos.


Abstract: The illicit trade of tobacco products, by enabling access to cheaper cigarettes, favors smoking initiation and hinders its cessation, minimizing the effects of price policy and taxes on reducing the demand for tobacco. This is especially the case among populations with lower income and schooling, where smoking is concentrated. Its confrontation requires multisectoral actions, aligned with the World Health Organization Framework Convention on Tobacco Control, supported by estimates of the illicit trade magnitude and the analysis of its characteristics. This study analyzes, based on samples of household solid waste collected in 2018 in the city of Rio de Janeiro, Brazil, the conformity of discarded cigarette packages with criteria for their regular commercialization in Brazil, classifying them as legal or illegal. The evaluation was also carried out for the 15 Planning Areas (PA) of the municipality. The Social Progress Index (SPI) was chosen to represent heterogeneities among PA. The average percentage of illegal cigarette packs found was 26.79%, ranging from 3.36% to 46.29% among PA. The PAs with high illegality presented lower Social Progress Index and lower percentages of legal cigarette packages with a price equal to or greater than BRL 7.25. Among the illegal packages, 98.07% were manufactured in Paraguay. The study contributes methodologically to measure the consumption of illegal cigarettes in the second economic capital of Brazil, supporting the National Tobacco Control Policy in the struggle against illicit trade of tobacco products and in the effective implementation of the pricing and tax policy on these products.

ABSTRACT

Objective: The aim of this study was to evaluate the influence of different crowns finishing line location on the crown tensile bond strength, marginal adaption and nanoleakage. Material and Methods: Sixty healthy third molars were collected. For tensile bond strength, a self-adhesive resin cement was used. For marginal adaption, epoxy resin models were prepared. Prior to tensile bond strength test, images for the epoxy resin models were measured under scanning electron microscopy (SEM). Nanoleakage was measured using same protocol. Failure mode was evaluated through SEM and classified: adhesive failure, cohesive in cement, cohesive in dentin, cohesive in resin composite, cohesive in enamel, and mixed. Statistical analysis was performed using Shapiro-Wilk and Kolmogorov Smirnov normality tests, two-way ANOVA, Bonferroni (posthoc) parametric test, with significance level of 5% (P < .05), Spearman correlation test. Results: tensile bond strength was not statistically different between the cemented groups with composite resin and ceramic. Cementation of ceramic was not statistically different between the groups (enamel, 3.28 Pa; dentin, 3.14 Pa; resin, 2.85 Pa). Marginal adaption was statistically different between resin and ceramic; finish line location varied between enamel and resin (175.91 µm vs. 433.58 µm). Nanoleakage rate was statistically different among all groups, except for resin: with resin (9.49%) and ceramic (9.35%). There was a predominance of adhesive failure in all groups. Conclusion: finish line location can be performed safely in enamel and dentin. Composite resinas substrate present an alternative, but still need to be more studied. Regarding the crown's material, it is possible to perform a satisfatory restoration in both: resin and ceramic. With ceramics presenting better results. (AU)


Objetivo: O objetivo deste estudo foi avaliar a influência da localização do término marginal na cimentação de coroas, na resistência à tração, adaptação marginal e nanoinfiltração, de acordo com os fatores: término marginal (dentina, esmalte e resina composta), e material restaurador (resina composta e cerâmica). Material e Métodos: Foram coletados 60 terceiros molares hígidos. Para o teste de resistência à tração, todas as amostras foram praparadas com término em chanfro e um cimento resinoso autoadesivo foi utilizado para a cimentação. Para a avaliação da adaptação marginal, foram confeccionados modelos em resina epóxica da linha de cimentação das amostras, previamente ao teste de tração, e submetidas à avaliação em microscopia eletrônica de varredura (MEV), para obtenção de imagens que posteriormente foram mensuradas. Para a nanoinfiltração, foram confeccionados fragmentos dos substratos e materiais restauradores, que foram cimentados com o mesmo protocolo. As amostras/imagens foram obtidas em MEV e mensurada a área infiltrada. O padrão de fratura foi avaliado através de imagens obtidas no MEV e classificados em: falha adesiva, coesiva em cimento, coesiva em dentina, coesiva em resina composta, coesiva em esmalte e mista. A análise estatística foi realizada utilizando os testes de normalidade Shapiro-Wilk e Kolmogorov Smirnov, ANOVA a dois fatores, teste paramétrico Bonferroni (post-hoc), com nível de significância de 5% (P <0,05), teste de correlação de Spearman. Resultados: a resistência à tração não foi estatisticamente diferente entre os grupos cimentados com resina composta e cerâmica. A cimentação da cerâmica não foi estatisticamente diferente entre os grupos (esmalte, 3,28 Pa; dentina, 3,14 Pa; resina, 2,85 Pa). A adaptação marginal foi estatisticamente diferente entre resina e cerâmica; a localização da linha de chegada variou entre esmalte e resina (175,91 µm vs. 433,58 µm). Para a nanoinfiltração foi estatisticamente diferente entre todos os grupos, exceto a resina: com resina (9,49%) e cerâmica (9,35%). Houve predomínio de falha adesiva em todos os grupos. Conclusão: a localização da linha de chegada pode ser realizada com segurança no esmalte e dentina. O substrato em resina composta apresenta uma alternativa promissora, mas ainda precisa ser mais estudado. Em relação ao material da coroa, é possível realizar uma restauração satisfatória tanto em resina composta quanto em cerâmica. Sendo a cerâmica, o material que apresentou melhores resultados. (AU)

ABSTRACT

Aim: Glass fiber posts are indicated in the rehabilitation of extensively damaged teeth; their cementation represents a critical step in restorative dentistry. The aim of this study was to quantify and compare the push-out bond strength of glass fiber posts cemented by conventional technique, two-step technique with luting agent and two-step technique associating bulk-fill composite and luting agent. Methods: Eighty maxillary bovine incisors were endodontically treated and divided into eight groups (n = 10) according to the luting agent (Rely X ARC and Duo-link) and cementation technique (conventional technique; two-step technique with luting agent; and two-step technique associating bulk-fill composite ­ Filtek Bulk-fill flow or Surefil SDR flow ­ and luting agent). Samples were submitted to pushout bond strength test, and the fracture pattern was evaluated through scanning electron microscope. Data were submitted to two-way ANOVA and Tukey's test (α = 0.05). Results: When Rely X ARC was used, the conventional cementation technique obtained higher bond strength values than the twostep technique associated with Filtek Bulk-fill flow. When Duolink was used, the two-step technique associated with Filtek Bulk-fill flow presented higher bond strength values than the conventional technique. The most prevalent fracture patterns were adhesive between luting agent and dentin, and adhesive between bulk-fill composite and dentin. Conclusion: Two-step cementation technique associated with bulk-fill composite may be promising depending on the luting agent used

ABSTRACT

A obesidade é uma doença crônica que envolve diversos fatores, e a partir dela muitas outras comorbidades ocorrem. Realizar a cirurgia bariátrica se tornou uma alternativa para muitas pessoas que não tiveram sucesso com outros tratamentos para emagrecer. Contudo, essa mudança acarreta questões psicológicas relacionadas ao comportamento social. O objetivo deste artigo é apresentar como os sentimentos de autoconfiança, autoestima e a percepção do Self são produzidos e discutir como a cirurgia bariátrica pode alterar a relação da pessoa com sua comunidade verbal e produzir efeitos em sua autoconfiança, autoestima e a percepção do Self. Foram selecionadas obras que apresentam a importância da comunidade verbal na pessoa, como sendo responsável pela construção da identidade de cada um, uma vez que ela se volta para o sobrepeso, alterar esse aspecto interfere em como ele se vê. Por isso, a importância do psicólogo analista do comportamento para auxiliá-lo nessa percepção de si.


Obesity is a chronic disease that involves several factors, and from it many other comorbidities occur. Performing bariatric surgery has become an alternative for many people who have not been successful with other weight loss treatments. However, this change raises psychological issues related to social behavior. The purpose of this article is to present how feelings of self-confidence, self-esteem and the perception of the Self are produced and discuss how bariatric surgery can alter the person's relationship with his verbal community and produce effects on his self-confidence, self-esteem and the perception of the Self. Works were selected that show the importance of the verbal community in the person, as being responsible for the construction of the identity of each person, once she turns to overweight, changing this aspect interferes with how she sees herself. Therefore, the importance of the behavior analyst psychologist to assist him in this perception of himself

ABSTRACT

Abstract: Background: Urticarias are frequent diseases, with 15% to 20% of the population presenting at least one acute episode in their lifetime. Urticaria are classified in acute ( ≤ 6 weeks) or chronic (> 6 weeks). They may be induced or spontaneous. Objectives: To verify the diagnostic and therapeutic recommendations in chronic spontaneous urticaria (CSU), according to the experience of Brazilian experts, regarding the available guidelines (international and US). Methods: A questionnaire was sent to Brazilian experts, with questions concerning diagnostic and therapeutic recommendations for CSU in adults. Results: Sixteen Brazilian experts answered the questionnaire related to diagnosis and therapy of CSU in adults and data were analyzed. Final text was written, considering the available guidelines (International and US), adapted to the medical practices in Brazil. Diagnostic work up in CSU is rarely necessary. Biopsy of skin lesion and histopathology may be indicated to rule out other diseases, such as, urticarial vasculitis. Other laboratory tests, such as complete blood count, CRP, ESR and thyroid screening. Treatment of CSU includes second-generation anti-histamines (sgAH) at licensed doses, sgAH two, three to fourfold doses (non-licensed) and omalizumab. Other drugs, such as, cyclosporine, immunomodulatory drugs and immunosuppressants may be indicated (non-licensed and with limited scientific evidence). Conclusions: Most of the Brazilian experts in this study partially agreed with the diagnostic and therapeutic recommendations of the International and US guidelines. They agreed with the use of sgAH at licensed doses. Increase in the dose to fourfold of sgAH may be suggested with restrictions, due to its non-licensed dose. Sedating anti-histamines, as suggested by the US guideline, are indicated by some of the Brazilian experts, due to its availability. Adaptations are mandatory in the treatment of CSU, due to scarce or lack of other therapeutic resources in the public health system in Brazil, such as omalizumab or cyclosporine.

ABSTRACT

Abstract Nowadays, postpartum hemorrhage is the major cause of maternal mortality and morbidity worldwide. Uterine atony is its main cause; thus, prophylactic measures, as well as medical and surgical fast approaches, have been developed to manage it. The uterine compression sutures are a possible treatment that preserves the uterus and, consequently, the fertility potential. Bearing that in mind, we report two cases of postpartum hemorrhage after caesarean section, successfully treated with a new modification of Pereira suture - longitudinal and transverse uterine sutures were applied after no response was registered to the first-line therapies. Both women recovered, and the postpartum evaluation revealed a normal uterus with an adequate blood supply, suggesting potential fertility, as described in the literature regarding this kind of therapeutic approach.


Resumo Atualmente, a hemorragia pós-parto é a maior causa de morbimortalidadematerna em todo o mundo. Sua principal causa é a atonia uterina, pelo que têm sido instituídas e desenvolvidas medidas profiláticas, bem como tratamentos médicos e cirúrgicos para esta complicação. As suturas uterinas de compressão representam uma possibilidade terapêutica que permite a preservação do útero e, por conseguinte, do potencial fértil. Tendo isso por base, apresentamos dois casos de hemorragia pós-parto após cesariana, que foram tratados com sucesso com uma nova modificação da sutura de Pereira - suturas uterinas longitudinais e transversais foram efetuadas após falha das terapias de primeira linha. Ambas as pacientes se recuperaram, e na reavaliação pós-parto objetivou-se um útero normal com manutenção de uma irrigação adequada, sugerindo a preservação do seu potencial fértil, tal como vem sendo descrito na literatura em relação a este tipo de procedimento.

ABSTRACT

Abstract To investigate how the hydrofluoric acid (HF) concentrations applied to a lithium disilicate glass-ceramic (EMX) affects the surface morphology and microtensile bond strength (μTBS) of ceramics to dentin, using light-cured resin cements with or without UDMA. Sixty-three EMX square ceramic blocks were etched for 20 seconds using different HF concentrations (1%, 5% and 10%) and luted to dentin using two types of resin cement combinations: BisGMA/TEGDMA and BisGMA/TEGDMA/UDMA (n = 10). Each bonded EMX-dentin block was sectioned to obtain 1 mm2 sticks for μTBS evaluation. Half of the sticks were tested after 24 hours and the other half was assessed after 6 months of water storage. Data were statistically assessed using split-plot three-way ANOVA and multiple comparisons were performed using the Tukey's post hoc test (α = 0.05). One EMX sample from each HF concentration was analyzed using field-emission scanning electron microscope (FE-SEM) to characterize the etching pattern. According to the FE-SEM images, increasing the concentration of HF from 1 to 5 and then to 10% led to increased removal of glassy matrix and greater exposure of lithium disilicate crystals. The 10% HF concentration yielded higher μTBS when compared to 1% for BisGMA/TEGDMA formulation (p < 0.05); whereas HF 1% and 5% showed similar μTBS values when compared to 10% HF for BisGMA/TEGDMA/UDMA resin matrix (p > 0.05) at both storage times. Water aging decreased the μTBS values (p < 0.05), except when 10% HF was associated with BisGMA/TEGDMA resin cement. Resin cement formulation and hydrofluoric acid concentrations can interfere with the immediate and long-term glass-ceramic bond strength to dentin.

ABSTRACT

Abstract The aim of this study was to analyze the efficiency of experimental light-curing resin cements (ERCs) with a ternary photo-initiator system containing diphenyliodonium hexafluorphosphate (DPI) and different amines on retention of glass-fiber posts to dentin (GFP). ERCs formulations: a 1:1 mass ratio of 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phenylpropane and triethyleneglycol dimethacrylate. Camphorquinone was used as initiator. Six experimental groups were established according to the amine used: [ethyl-4-(dimethylamino)benzoate-EDMAB or 2-(dimethylamino)ethyl methacrylate-DMAEMA] and the concentration of DPI (0, 0.5 mol%, 1 mol%). The resin cements Variolink II (dual- and light-cured versions) were used as commercial reference. Eighty recently extracted bovine incisors (n = 10) were selected for this study. The roots were prepared and the fiber posts were cemented with the resin cement specified for each experimental group. Specimens from coronal, middle, and apical thirds of the root were subjected to push-out bond strength test 24 hours after bonding. Data were subjected to split-plot ANOVA and the Tukey test (p = 0.05). ERCs containing DPI showed statistically significant higher bond strengths compared with ERCs without DPI. ERCs containing DPI were statistically similar to VARIOLINK II - dual-cured and superior to VARIOLINK II - light-cured (except for EDMAB - 1DPI in the medium third and DMAEMA - 1DPI in the coronal third). Different amines did not influence post retention. The apical root region showed the lowest bond strength for the groups EDAB-0DPI, DMAEMA-0DPI and VARIOLINK II light-cured. Light-cured ERCs containing DPI were efficient for GFP retention to radicular dentin, with similar behaviour to that of dual-curing commercial resin cement.

ABSTRACT

ABSTRACT Objective: To characterize clinically all of the patients with spontaneous pneumomediastinum (SPM) admitted to an adult pulmonology ward in Lisbon, Portugal. Methods: This was a retrospective descriptive study of all adult patients (≥ 18 years of age) diagnosed with SPM between January of 2004 and September of 2015. Results: At least one predisposing factor was identified in most (88.9%) of the 18 patients who presented with SPM during the study period. With regard to precipitating factors, bouts of cough were present in 50.0% of the patients. Other precipitating factors included a sudden increase in tobacco consumption, inhaled drug use, occupational inhalation of varnish fumes, intense exercise, and vomiting. The most common complaints were dyspnea (in 83.3%) and chest pain (in 77.8%). Other complaints included cough, neck pain, dysphagia, and odynophagia. Subcutaneous emphysema was found in most of the patients. The diagnosis of SPM was based on chest X-ray findings in 61.1% of the patients. Conclusions: Although SPM is a rare condition, it should be considered in the differential diagnosis of chest pain and dyspnea. It can develop without a triggering event or conclusive findings on a chest X-ray, which is usually sufficient for diagnosis.


RESUMO Objetivo: Caracterizar clinicamente todos os pacientes com pneumomediastino espontâneo (PME) admitidos em uma enfermaria de pneumologia para adultos em Lisboa, Portugal. Métodos: Estudo descritivo retrospectivo no qual foram analisados todos os pacientes adultos (≥ 18 anos de idade) com diagnóstico de PME entre janeiro de 2004 e setembro de 2015. Resultados: Pelo menos um fator predisponente foi identificado na maioria (isto é, em 88,9%) dos 18 pacientes que apresentaram PME durante o período de estudo. No tocante a fatores precipitantes, crises de tosse ocorreram em 50,0% dos pacientes. Outros fatores precipitantes foram um aumento repentino do consumo de tabaco, uso de drogas inalatórias, inalação ocupacional de vapores de vernizes, exercício intenso e vômitos. As queixas mais comuns foram dispneia (em 83,3%) e dor torácica (em 77,8%). Outras queixas foram tosse, cervicalgia, disfagia e odinofagia. Constatou-se a presença de enfisema subcutâneo na maioria dos pacientes. O diagnóstico de PME baseou-se na radiografia de tórax em 61,1% dos pacientes. Conclusões: Embora seja uma doença rara, o PME deve ser levado em conta no diagnóstico diferencial de dor torácica e dispneia. O PME pode surgir sem um evento desencadeante e sem achados conclusivos na radiografia de tórax, que é geralmente suficiente para o diagnóstico.
