ABSTRACT

Abstract This study assessed the color-matching ability and color recovery of unprepared teeth when using single-shade composites and a universal composite in large restorations. Buccal and palatine surface colors of molars were measured with a spectrophotometer (CIELAB) before preparing round cavities (6 mm in diameter, 2 mm in depth). The cavities were randomly filled with a single-shade composite (Omnichroma, Diamond One, or Vittra APS Unique) or a universal composite (Filtek Universal). Color measurements of the restored cavities were taken, and overall color differences (ΔEab and ΔE00) and differences in the whitening index for dentistry (ΔWID) from baseline were calculated. Additionally, visual assessments of a color match to the surrounding enamel were performed by forty evaluators (laypersons and undergraduate students of dentistry) in a viewing booth under illuminant D65, with rating scores from 0 (no color mismatch) to 4 (not acceptable). Data were analyzed using RM or one-way ANOVA (α = 0.05). Results showed that the restorations generally exhibited whiter colors (WID ranged from 27.9 to 41.3) than the unprepared teeth (WID ranged from 15.9 to 19.3). The composite Filtek Universal demonstrated the lowest color discrepancy (ΔWID = 8.6; ΔE00 = 10.8; and ΔE00 = 6.2), and no significant differences were observed among the evaluated single-shade composites. Furthermore, all composites showed similar and adequate color matches to the surrounding enamel. However, it is important to note that despite their ability to match the surrounding enamel reasonably, none of the composites evaluated in large restorations fully recovered the color observed in unprepared teeth.


Resumo Este estudo avaliou a habilidade de combinação de cores e recuperação de cor de dentes não preparados ao utilizar resinas compostas de única tonalidade e uma resina composta universal em grandes restaurações. As cores das superfícies bucais e palatinas de molares foram medidas com um espectrofotômetro (CIELAB) antes de preparar cavidades esféricas (6 mm de diâmetro, 2 mm de profundidade). As cavidades foram preenchidas aleatoriamente com uma resina composta de única tonalidade (Omnichroma, Diamond One ou Vittra APS Unique) ou com uma resina composta universal (Filtek Universal). Foram realizadas medições das cores das cavidades restauradas e calculadas as diferenças de cor globais (ΔEab and ΔE00)) e as diferenças no índice de clareamento para odontologia (ΔWID) em relação à cor inicial. Além disso, foram realizadas avaliações visuais da correspondência de cor com o esmalte circundante por quarenta avaliadores (leigos e estudantes de odontologia) em uma cabine de visualização sob iluminante D65, com pontuações de 0 (nenhuma discrepância de cor) a 4 (não aceitável). Os dados foram analisados usando RM ou ANOVA unidirecional (α = 0,05). Os resultados mostraram que as restaurações geralmente apresentavam cores mais brancas (WID variou de 27,9 a 41,3) do que os dentes não preparados (WID variou de 15,9 a 19,3). A resina composta Filtek Universal demonstrou a menor discrepância de cor (ΔWID = 8,6; ΔE00 = 10,8; and ΔE00 = 6,2), e não foram observadas diferenças significativas entre as resinas compostas de única tonalidade avaliadas. Além disso, todas as resinas compostas apresentaram correspondência de cor similar e adequada com o esmalte circundante. No entanto, é importante observar que, apesar de sua capacidade de corresponder razoavelmente com o esmalte circundante, nenhuma das resinas compostas avaliadas em grandes restaurações recuperou completamente a cor observada nos dentes não preparados.

ABSTRACT

Abstract Repositioning guides are commonly employed in clinical studies to ensure consistent tooth color measurements. Yet, their influence on measured color remains uncertain. Objective This study evaluated the impact of repositioning guides' color and usage on tooth color measurement using a clinical spectrophotometer. Methodology In total, 18 volunteers participated in this study, in which the color of their upper left central incisor and upper left canine was measured with or without repositioning guides (control). The guides were made from pink, blue, or translucent silicone, as well as an acetate-based bleaching tray. Tooth color was measured in triplicates using a clinical spectrophotometer based on the CIELAB system. The standard deviations of these readings were used to estimate reproducibility, and color differences (ΔE00) between the measurements with guides and the control were calculated. Results Repositioning guides had a minimal effect on L* values and no effect on b* values. The use of pink silicone increased a* values, whereas blue or translucent silicone reduced them. Irrespective of the evaluated tooth, the lowest ΔE00 values were observed for the translucent silicone and bleaching tray. The usage of guides only affected data variability for the L* color coordinate. Conclusion Using repositioning guides can significantly impact the precision of tooth color measurement with a clinical spectrophotometer.

ABSTRACT

Abstract This study analyzed the prevalence of lectures involving esthetics in the scientific program of Brazilian dental conferences and the gender distribution of speakers. All lectures presented in three dental conferences (Bahia, São Paulo, and Goiás states) held from 2016 to 2020 were evaluated. Three investigators individually divided the lectures according to the specialties recognized by the Brazilian Federal Council of Dentistry (FCD) based on their titles. The lectures were also classified as involving or not esthetics, and the speaker`s gender was recorded. Descriptive statistical analyses were performed, and Chi-square tests assessed possible associations between factors. The words most cited in the titles of the lectures were "esthetic" (13.6%), "dentistry" (9.9%), and "treatment" (8.1%). Oral diseases were barely mentioned in the titles (up to 1.3%). The highest number of lectures was observed for the specialty of Restorative Dentistry (22.3%), followed by Prosthodontics (18.5%). Approximately one-third of lectures involved some aesthetic aspect, but this percentage ranged from 71.9 to 78.6% for the two specialties with more lectures. Regarding the speaker`s gender, the inequity was higher for lectures involving esthetics (81.6% of males) than for topics unrelated to esthetics (66.7%). More male speakers than females were observed for all specialties. The highest gender gap was observed for Pediatric Dentistry with 62.4% male speakers, although only 10.6% of FCD registered specialists were men. In conclusion, the Brazilian dental conferences analyzed seemed to favor offering lectures dealing with esthetic topics and male speakers.


Resumo Este estudo analisou a prevalência de palestras envolvendo estética na programação científica de congressos de Odontologia brasileiros, e a distribuição do gênero dos palestrantes. Todas as palestras apresentadas em três congressos de Odontologia (CIOBA, CIOGO, and CIOSP) entre 2016 e 2020 foram avaliadas. Três avaliadores utilizaram os títulos das palestras para dividi-las entre as especialidades reconhecidas pelo Conselho Federal de Odontologia (CFO) do Brasil. As palestras foram também classificadas como envolvendo ou não estética, e o gênero do palestrante foi registrado. Análises estatísticas descritivas foram realizadas, e testes de Qui-quadrado avaliaram possíveis interações entre fatores. A palavra mais citada nos títulos das palestras foi "estética" (13,6%), seguido por "odontologia" (9,9%) e "tratamento" (8,1%). Doenças orais foram raramente mencionadas nos títulos (até 1,3%). O maior número de palestras foi observado para a especialidade de Dentística (22,3%), seguido por Prótese Dental (18,3%). Aproximadamente um terço das palestras envolviam algum aspecto estético, com porcentagens entre 71,9 a 78,6% para as duas especialidades com mais palestras. Em relação ao gênero do palestrante, a inequidade foi maior para palestras envolvendo estética (81,6% de homens) que para tópicos não relacionadas à estética (66,7%). Mais palestrantes do sexo masculino que feminino foram observados para todas as especialidades. A maior discrepância entre os gêneros foi observada para Odontopediatria, uma especialidade com 62,4% dos palestrantes do sexo masculino, embora apenas 10,6% dos especialistas registrados no CFO eram homens. Como conclusão, os congressos de Odontologia Brasileiros parecem preferir palestras abordando tópicos de estética e palestrantes do sexo masculino.

ABSTRACT

BACKGROUND Culex quinquefasciatus, a cosmopolitan, domestic, and highly anthropophilic mosquito, is a vector of pathogenic arboviruses such as West Nile virus and Rift Valley virus, as well as lymphatic filariasis. The current knowledge on its reproductive physiology regarding vitellogenin expression in different tissues is still limited. OBJECTIVES In this study, we analysed the transcriptional profiles of vitellogenin genes in the fat body and ovaries of C. quinquefasciatus females during the first gonotrophic cycle. METHODS C. quinquefasciatus ovaries and/or fat bodies were dissected in different times during the first gonotrophic cycle and total RNA was extracted and used for reverse transcription polymerase chain reaction, quantitative real time-PCR, and in situ hybridisation. FINDINGS We confirmed the classical descriptions of the vitellogenic process in mosquitoes by verifying that vitellogenin genes are transcribed in the fat bodies of C. quinquefasciatus females. Using RNA in situ hybridisation approach, we showed that vitellogenin genes are also transcribed in developing ovaries, specifically by the follicle cells. MAIN CONCLUSIONS This is the first time that vitellogenin transcripts are observed in mosquito ovaries. Studies to determine if Vg transcripts are translated into proteins and their contribution to the reproductive success of the mosquito need to be further investigated.

ABSTRACT

Abstract This study evaluated the background and effect of surrounding colors on the color blending of a single-shade composite used in a thin layer. Disc-shaped specimens (1.0 mm thickness) were built with the Vittra APS Unique composite surrounded (dual specimens) or not surrounded (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens were also built with only control composites. The specimen color was measured against white and black backgrounds with a spectrophotometer (CIELAB system). The whiteness index for dentistry (WID) was calculated for simple specimens. Differences (ΔE00) in color and translucency parameters (ΔTP00) between the simple/dual specimens and the controls were calculated. The translucency adjustment potential (TAP) and color adjustment potential (CAP) were estimated based on the ratios between data from simple and dual specimens. The Vittra APS Unique composite showed higher WID values than the controls. No differences between ΔTP00_SIMPLE and ΔTP00_DUAL were observed for any of the shades. The composite shade did not affect TAP values. The lowest values of ΔE00_SIMPLE and ΔE00_DUAL were observed for shade A1 regardless of the background color. For the white background, ΔE00_SIMPLE values did not differ from those of ΔE00_DUAL for all shades. Only A1 showed ΔE00_DUAL values lower than ΔE00_SIMPLE when the black background was used. The highest modulus of CAP (negative values for the white background) was observed when shade A1 surrounded the Vittra APS Unique composite. The color blending ability of the single-shade resin composite used in a thin layer was affected by both the surrounding shade and background color.

ABSTRACT

Abstract This study evaluated surface roughness, color stability, whitening index, and opacity of different types of modeling liquids for resin composite coating after exposure to staining and toothbrushing. Disc-shaped resin composite (Vittra APS, FGM) specimens were fabricated and divided into four groups (n = 10 each): control group, Composite Wetting resin (Ultradent Products), Adper Scotchbond Multipurpose adhesive (3M ESPE), and Adper Universal adhesive (3M ESPE). Surface roughness (Ra) was measured using a rugosimeter, while color stability (∆E00), whitening index (WI), and opacity (%) were measured using a spectrophotometer. Assessments were made at four time points: after polishing (baseline, T1), after immersion in red wine for 24 h (T2), and after 5,000 (T3) and 10,000 (T4) cycles of toothbrushing. Scanning electron microscopy images were captured to analyze the scratches created. The data were statistically analyzed by two-way repeated-measures analysis of variance and Tukey's honestly significant difference tests (α = .05). Modeling with the Wetting resin resulted in higher surface roughness (p < 0.05) and low color stability, which were attributable to porosities. Higher color change values were observed in the control group after staining. Both adhesives showed the lowest mean ΔE00 values (p < 0.005). WI decreased after staining, except with the use of the Universal adhesive (p < 0.005). The lowest opacity values were observed at baseline for all groups (p < 0.005). The Universal and Scotchbond adhesives had lower surface roughness, better color stability, higher WI, and the lowest opacity values after staining with red wine and toothbrushing.

ABSTRACT

Resumo O desenho institucional do Sistema Nacional de Meio Ambiente (Sisnama) atribui aos municípios responsabilidades complexas e, muitas vezes, inviáveis em termos financeiros, técnicos e operacionais. Diante disso, a cooperação surge como uma alternativa para enfrentar a ausência de recursos e a incapacidade de alguns municípios executarem, de maneira isolada, as diretrizes previstas pela Política Nacional de Meio Ambiente (PNMA). Esta pesquisa examina a relação entre cooperação intermunicipal e capacidade estatais municipais na implementação da política ambiental no Brasil, visando identificar se essas capacidades, em suas diferentes dimensões, têm características relevantes para os municípios que participam de consórcios públicos na área de meio ambiente. Com o uso de dados secundários, a pesquisa empregou uma abordagem quantitativa, por meio da análise de regressão logística, investigando a incidência dos arranjos cooperativos intermunicipais para 4.479 municípios brasileiros. Os resultados encontrados demonstraram, em linhas gerais, que, na implementação em nível local da PNMA, uma alta capacidade administrativa e maior desempenho fiscal tendem a diminuir os incentivos para o município cooperar com outros, enquanto a disponibilidade de capacidade técnica, político-relacional e institucional aumenta a probabilidade de cooperação.


Resumen El diseño institucional del Sistema Nacional Ambiental asigna responsabilidades complejas a los municipios, muchas veces inviables en términos financieros, técnicos y operativos. Ante esto, la cooperación surge como una alternativa para enfrentar la falta de recursos y la incapacidad de algunos municipios para ejecutar los lineamientos previstos por la Política Nacional Ambiental (PNMA) de manera aislada. Esta investigación examina la relación entre la cooperación intermunicipal y las capacidades estatales municipales en la implementación de la política ambiental en Brasil, con el objetivo de identificar si las capacidades estatales, en sus diferentes dimensiones, tienen características relevantes para los municipios que participan en consorcios públicos en el área de medio ambiente. Con base en el uso de datos secundarios, la investigación emplea un enfoque cuantitativo, a través del análisis de regresión logística, investigando la incidencia de los arreglos cooperativos intermunicipales para 4.479 municipios brasileños. Los resultados encontrados demuestran, en términos generales, que en la implementación a nivel local de la PNMA, una alta capacidad administrativa y un mayor desempeño fiscal tienden a reducir los incentivos para que el municipio coopere con otros, mientras que la disponibilidad de recursos técnicos, la capacidad político-relacional e institucional aumenta la probabilidad de cooperación.


Abstract The institutional framework of the National Environmental System assigns complex responsibilities to municipalities, which are often unviable in financial, technical, and operational terms. Cooperation emerges as an alternative to face the lack of resources and the inability of some municipalities to execute the guidelines provided for by the National Environmental Policy in an isolated way. This research examines the relationship between intermunicipal cooperation and municipal state capacities in the implementation of the environmental policy in Brazil, aiming to identify if state capacity, in different dimensions, is a relevant characteristic for municipalities participating in environmental public consortiums. This research used secondary data to employ a quantitative approach through logistic regression analysis, investigating the occurrence of intermunicipal cooperative arrangements in 4.479 Brazilian municipalities. In general terms, the results demonstrate that high administrative capacity and greater fiscal performance tend to reduce the incentives for the municipality to cooperate with others while implementing the PNMA at the local level. Also, the findings indicate that the availability of technical, political-relational, and institutional capacity increases the probability of cooperation.

ABSTRACT

Abstract This study evaluated the effect of surrounded shade and specimens` thickness on the color adjustment potential (CAP) of a single-shade composite. The composite Vittra APS Unique was surrounded (dual specimens) or not (simple specimens) by a control composite (shade A1, A2, or A3). Simple specimens of the control composite were also confectioned. Opacity and whiteness index for dentistry (WID) were calculated for simple specimens. Color differences between the simple (ΔE*SIMPLE)/ dual specimens (ΔE*DUAL) and the controls were calculated. CAP was calculated based on the ratio between ΔE* SIMPLE and ΔE* DUAL. The tested composite presented lower opacity (53 to 62% vs. 80 to 93%) and higher WID (≈ 42 vs. 18 to 32) than controls. Irrespective of the specimens' thickness (1.0/ 1.5 mm), the lowest values of ΔE* SIMPLE (11.1/ 10.8) and ΔE*DUAL (7.2/ 6.1) were observed using the surrounding shade A1. The shade A3 yielded higher ΔE*SIMPLE (16.4/ 17.1) and ΔE* DUAL (11.3/ 12.3) than the A2 (ΔE*SIMPLE = 13.4/ 14.6; and ΔE* DUAL = 9.7/ 10.3). The specimen`s thickness significantly affected the CAP (0.35 and 0.44 for 1.0 and 1.5 mm, respectively) only for shade A1, which had the highest CAP values. The shade A3 resulted in higher CAP values (0.31) than A2 (0.27) when 1.0-mm thick specimens were used, but similar values were observed for 1.5 thick specimens (≈ 0.29). In conclusion, both surrounding shade and specimen thickness can affect the CAP of a single-shade resin composite.


Resumo Este estudo avaliou o efeito da cor circundante e da espessura da amostra no potencial de ajuste de cor (PAC) de uma resina monocromática. O compósito Vittra APS Unique foi circundado (amostras duplas) ou não (amostras simples) com um compósito controle (cor A1, A2 ou A3). Amostras simples do compósito controle também foram confeccionadas. A opacidade e o índice de brancura para odontologia (IBO) foram calculados para as amostras simples. As diferenças de cor entre amostras simples (ΔE*SIMPLE) / duplas (ΔE*DUAL) e os controles foram calculados. PAC foi calculado baseado na razão entre ΔE* SIMPLE e ΔE* DUAL. O compósito testado apresentou menor opacidade (53 a 62% vs. 80 a 93%) e maior IBO (≈ 42 vs. 18 a 32) que os controles. Independente da espessura da amostra (1,0/ 1,5 mm), os valores mais baixos de ΔE* SIMPLE (11,1/ 10,8) e ΔE*DUAL (7,2/ 6,1) foram observadas quando a resina circundante era A1. A cor A3 resultou em maior ΔE*SIMPLE (16,4/ 17,1) e ΔE* DUAL (11,3/ 12,3) do que A2 (ΔE*SIMPLE = 13,4/ 14,6; e ΔE* DUAL = 9,7/ 10,3). A espessura das amostras afetou significativamente o PAC (0,35 e 0,44 para 1,0 e 1,5 mm, respectivamente) apenas para a cor A1, que teve os maiores valores de PAC. A cor A3 resultou nos maiores valores de PAC (0,31) que A2 (0,27) quando amostras de 1,0 mm de espessura foram usadas, mas valores similares foram observados para amostras de 1,5 mm (≈ 0,29). Como conclusão, tanto a cor circundante como a espessura das amostras podem afetar o PAC de um compósito resinoso monocromático.

ABSTRACT

Abstract Background: Due to the growing concern about work-related social and health aspects, occupational health and safety has become relevant. Objective: This work aims to develop a model to assist cardiovascular risk management in a team of haul truck operators, who work in rotating shifts at a mining company in Brazil. Methods: This longitudinal study evaluated risk factors for cardiovascular diseases of 191 mineworkers at three times points - 2010, 2012, and 2015. In addition, the risk of developing cardiovascular diseases was calculated, and the risk factors were analyzed using the chi-square test, the U Mann-Whitney test, and binary logistic regression. The significance level was set at 5%. Results: In the study period, body weight, body mass index (BMI), waist-to-height ratio (WHR), systolic (SBP), and diastolic blood pressure (DBP), total cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides levels of the study group increased. In 2015, there was a high prevalence of alcohol intake, overweight or obesity, central obesity, inadequate WHR, high blood pressure, total cholesterol above 190 mg/dL, and triglycerides above 150 mg/dL. An association was identified between increased cardiovascular risk and age, SBP, HDL-C, low-density lipoprotein cholesterol (LDL-C), and elevated glucose levels. Conclusion: Intense interventions for reduction and prevention of elevated alcohol intake, blood pressure levels, WHR, metabolic syndrome, blood glucose, and LDL-C levels, and low HDL-C levels are needed. In addition, a close monitoring of mine workers over 38 years of age who smoke, consume alcoholic beverages, and have altered blood glucose levels is important.

ABSTRACT

Resumo A partir de um estudo de caso do Rio Grande do Norte, este artigo discute o papel dos estados na coordenação da saúde durante a pandemia do novo coronavírus. A ausência de coordenação federal no enfrentamento do surto pandêmico no Brasil tem sido compreendida por diversos analistas como algo inédito na federação brasileira, rompendo com um padrão recorrente de normatização e indução nacional por diferentes governos desde a Constituição de 1988. Nesse sentido, estados e municípios passaram a adotar iniciativas próprias para o enfrentamento da pandemia. A partir de uma pesquisa qualitativa baseada em dados documentais - mídia local, boletins epidemiológicos e regulamentações estaduais - e em entrevistas semiestruturadas com gestores estaduais e municipais, foi possível identificar mudanças na relação estado-municípios durante a pandemia no Rio Grande do Norte, caso marcado, historicamente, pela ausência de cooperação estadual. A pandemia, dessa forma, funcionou como um choque exógeno, que induziu uma mudança no padrão de atuação do governo estadual na saúde. Não está claro, porém, se essas alterações são pontuais ou permanentes, na medida em que o peso do autorreforço - especificação dos efeitos do legado histórico - atua como um mecanismo que produz dinâmicas inerciais de difícil rompimento com o passado.


Abstract From a case study of the State of Rio Grande do Norte, in Brazil, this article discusses the role of states in coordinating healthcare with its local governments in the context of the new coronavirus pandemic. The absence of federal government initiatives in responding to the pandemic in Brazil have been acknowledged by several specialists as an unprecedented event in the Brazilian federation, breaking with a recurrent pattern of national coordination and regulation by different governments since the 1988 Constitution. In this sense, states and municipalities had to adopt their own initiatives to respond to the pandemic. Qualitative research based on the collection of documents (local media, epidemiological reports, and state regulations) and in-depth interviews with state and municipal managers reveals significant changes in the state-municipal relationship throughout the pandemic period in Rio Grande do Norte, a state historically characterized by the lack of state coordination. The pandemic, thus, functioned as an exogenous shock, which induced changes in the pattern of state coordination in healthcare. It is unclear, however, whether these changes are one-off or permanent since the weight of increasing returns - a specification of a path dependency process - seem to work as a mechanism producing inertial dynamics of difficult disruption with the past.

ABSTRACT

Objetivo: descrever perante a literária as ações da enfermagem no cuidado a mulheres vítimas de violência doméstica, identificando falhas nas práticas e dimensões do cuidar. Método: Trata-se de um estudo de revisão narrativa da literatura, com abordagem qualitativa exploratória, realizada em abril de 2021, no qual foram abordados artigos científicos, pesquisados através dos Descritores em Ciências da Saúde: "Cuidados de enfermagem", "Violência contra a mulher", "Violência doméstica", "Assistência à mulher", "Lei Maria da Penha", obtidos através das seguintes bases: Biblioteca Virtual Em Saúde; Literatura Latino-Americana e do Caribe em Ciências da Saúde, Scientific Eletronic Library On-line e documentos e normativas do Ministério da Saúde e do Conselho Federal de Enfermagem. Foram incluídos documentos publicados entre os anos de 2015 a 2021, que tinham ligação considerável com o tema proposto, e excluídos materiais que foram publicados antes de 2014 ou que não apresentavam ligação considerável com o tema. Resultados: Após a seleção dos documentos que atendiam aos critérios de inclusão e exclusão estabelecidos, foram selecionados 11, considerados pertinentes para o estudo. O enfermeiro se configura como o profissional que recebe as mulheres prioritariamente, tanto na atenção básica quanto nos prontos socorros, devendo, assim, proporcionar um diálogo amigável, gerando um elo de confiança entre profissional e vítima, promovendo intimidade e fornecendo segurança para que elas se sintam confortáveis para relatar o ocorrido e, por conseguinte, tomar as decisões prioritárias. Conclusão: A conduta do enfermeiro não seria possível sem a equipe multiprofissional e o auxílio da rede em saúde, frente aos cenários de violência contra a mulher.


Objective: to describe before the literary the actions of nursing in the care of women victims of domestic violence, identifying flaws in the practices and dimensions of care. Method: This is a narrative review study of the literature, with exploratory qualitative approach, carried out in April 2021, in which scientific articles were addressed, researched through the Descriptors in Health Sciences: "Nursing Care", "Violence against women", "Domestic violence", "Women's Care", "Maria da Penha Law", obtained through the following databases: Virtual Health Library; Latin American and Caribbean Literature on Health Sciences, Scientific Electronic Library Online and documents and regulations of the Ministry of Health and the Federal Council of Nursing. We included documents published between 2015 and 2021, which had considerable links with the proposed theme, and excluded materials that were published before 2014 or that were not significantly linked to the subject. Results: After the selection of documents that met the inclusion and exclusion criteria established, 11 were selected, considered relevant for the study. The nurse is configured as the professional who receives women primarily, both in primary care and in the emergency room, and should thus provide a friendly dialogue, generating a link of trust between professional and victim, promoting intimacy and providing security so that they feel comfortable to report what happened and, consequently, make priority decisions. Conclusion: The conduct of nurses would not be possible without the multidisciplinary team and the help of the health network, in view of the scenarios of violence against women.

Método: Se trata de un estudio de revisión narrativa de la literatura, con enfoque cualitativo exploratorio, realizado en abril de 2021, en el que se abordaron artículos científicos, investigados a través de los Descriptores en Ciencias de la Salud: "Cuidados de Enfermería", "Violencia contra las mujeres", "Violencia doméstica", "Cuidado de las mujeres", "Ley Maria da Penha", obtenidos a través de las siguientes bases de datos: Biblioteca Virtual de Salud; Literatura Latinoamericana y del Caribe en Ciencias de la Salud, Biblioteca Científica Electrónica en Línea y documentos y reglamentos del Ministerio de Salud y del Consejo Federal de Enfermería. Se incluyeron documentos publicados entre 2015 y 2021, que tenían vínculos considerables con el tema propuesto, y se excluyeron los materiales que se publicaron antes de 2014 o que no estaban significativamente vinculados al tema. Resultados: Tras la selección de documentos que cumplieron con los criterios de inclusión y exclusión establecidos, se seleccionaron 11, considerados relevantes para el estudio. La enfermera se configura como la profesional que recibe a las mujeres principalmente, tanto en atención primaria como en urgencias, y así debe brindar un diálogo amistoso, generando un vínculo de confianza entre profesional y víctima, promoviendo la intimidad y brindando seguridad para que se sientan cómodas para denunciar lo sucedido y, en consecuencia, tomar decisiones prioritarias. Conclusión: La conducta de las enfermeras no sería posible sin el equipo multidisciplinario y la ayuda de la red de salud, en vista de los escenarios de violencia contra las mujeres

ABSTRACT

Aim: The literature has not yet reported investigations about the effect of laser photobiomodulation (LPBM) over the cytotoxicity of drugs for endodontic treatments. Thus, the aim of this study was to evaluate, in vitro, the effect of the association between LPBM and intracanal medications on fibroblasts viability in different exposure times. Methods: Calcium hydroxide (Ca(OH)2) and iodoform (IO) were used pure or associated to LPBM. Eluates of medications were prepared and placed in contact with the cells in three different periods: 24h, 48h and 72h. Laser irradiation (emitting radiation λ 660nm, power density of 10mW, energy density of 3 J/cm²) has been performed in two sessions within a six hour interval, for 12s per well. After each experimental time, the colorimetric assay (MTT) has been performed. Statistical analysis was applied for Mann-Whitney test with 5% α error admitted test. Results: At 24h, the use of LPBM did not increase cell viability while after 72h cell proliferation was stimulated in the group without medications. LPBM application did not increase cell viability in Ca(OH)2 group and IO at any tested time. Ca(OH)2 cytotoxicity at 24h was higher than iodoform, while at 72h not difference was observed. Therefore, after 72 hours was no statistical difference between the IO and Ca(OH)2 groups. Conclusion: LPBM was able to increase cell viability in 72h in the group without medication, although no improvement was observed in the other groups. Thus, LPBM was not able to reduce the cytotoxic effects of the materials on fibroblasts in vitro

ABSTRACT

Abstract: This study investigated the bleaching effectiveness and the physicochemical effects on enamel of violet light and ozone, associate or not to hydrogen peroxide, compared to 35%-hydrogen peroxide. Enamel-dentin blocks from human molars were randomly allocated to receive one of the following bleaching protocols (n=15): (HP) 35%-hydrogen peroxide, (VL) violet light, (OZ) ozone, the association between hydrogen peroxide with ozone (OZ+HP) or violet light (VL+HP). All protocols were performed in two sessions with a 48h interval. Color (spectrophotometer) and mineral composition (Raman spectroscopy) were measured before and after the bleaching. Color changes were calculated by ΔEab, ΔE00, and whitening index (WI). The surface roughness was measured with an atomic force microscope. Data were analyzed by One-way or Two-way repeated measure ANOVA followed by the Tukey's test (α = 0.05). The lowest color change values (either measured by WI, ΔEab, or ΔE00) were observed for VL and OZ used with no HP. Violet light associate with HP was unable to improve the color changes observed for the peroxide alone, in combination with OZ and HP, the highest color changes were verified. Regardless of bleaching protocol, the bleached enamel presented higher contents of PO4 and CO3 -2 than those observed at baseline. All bleaching protocols resulted in similar enamel surface roughness. Both the VL and the OZ caused reduced effects on the enamel color change when used alone. The ozone therapy improved the bleaching effect in the group that received the association of HP.


Resumo O objetivo deste estudo foi avaliar o efeito clareador e físico-químico no esmalte de luz violeta e ozônio, associado ou não ao peróxido de hidrogênio, comparado a 35% de peróxido de hidrogênio. Blocos de esmalte-dentina de molares humanos foram alocados aleatoriamente para receber um dos seguintes protocolos de clareamento (n = 15): (HP) peróxido de hidrogênio a 35%, (VL) luz violeta, (OZ) ozônio, a associação entre peróxido de hidrogênio com ozônio (HP+OZ) ou luz violeta (HP+VL). Todos os protocolos foram realizados em duas sessões, com intervalo de 48 horas entre eles. A cor (espectrofotômetro) e a composição mineral (espectroscopia Raman) do dente foram medidas antes e após os procedimentos de clareamento. As alterações de cor foram calculadas por ΔEab e ΔE00, e o índice de brancura foram calculados. A rugosidade da superfície das amostras clareadas foi medida por microscópio de força atômica. Os dados foram analisados por ANOVA One way ou ANOVA two way de medidas repetidas seguida pelo teste de Tukey (α = 0,05). Os menores valores de alterações de cor (medidos por WI, ΔEab ou ΔE00) foram observados para VL e OZ usados na ausência de HP. VL associada ao HP não foi capaz de melhorar as alterações de cor observadas com o uso do HP, mas a combinação de OZ e HP produz as maiores alterações de cor. Independentemente do protocolo de clareamento, o esmalte clareado apresentou maiores teores de PO4 e CO3 -2 do que os observados inicialmente. Não foi observada diferença significativa entre os protocolos de clareamento testados em relação à rugosidade da superfície do esmalte. É possível concluir que a VL ou o OZ tiveram efeitos reduzidos na mudança de cor do esmalte quando usados sozinhos. A terapia com OZ melhorou o efeito clareador do HP.

ABSTRACT

Este estudo teve por objeto o processo de diagnóstico da soro positividade para o HIV e por objetivos: descrever processo de revelação do diagnóstico positivo para HIV e discutir a vivência do preconceito e suas consequências para vida cotidiana. Método: Entrevistas com 49 pessoas que vivem com HIV (PVHIV). Técnica de análise de conteúdo lexical, com auxílio do software Iramuteq 0.7 alpha 2. Resultados: As condições de vida de pessoas que vivem com HIV são permeadas pelo estigma, preconceito e discriminação. A revelação do diagnóstico para a sociedade não é uma tarefa fácil e nem sempre ocorre. Após impacto inicial do diagnóstico, a vida segue com mudanças cotidianas, os sentimentos de desespero e medo são aplacados com o tempo, entretanto o preconceito persiste. Conclusão: Os resultados mostram complexo cenário de se (con) viver com o vírus e /ou com a síndrome. A descoberta do diagnóstico, aceitação, decisão sobre revelação, reunir meios de enfrentamento do preconceito e prosseguir vivendo, exige que PVHIV tenham suporte e se reprogramem para enfrentar desafios diários.


This study had as its object the process of diagnosing serum positive for HIV and its objectives: to describe the process of disclosing the positive diagnosis for HIV and to discuss the experience of prejudice and its consequences for everyday life. Method: Interviews with 49 people living with HIV (PLHIV). Lexical content analysis technique, with the aid of the Iramuteq 0.7 alpha 2 software. Results: The living conditions of people living with HIV are permeated by stigma, prejudice and discrimination. Disclosing the diagnosis to society is not an easy task and does not always occur. After the initial impact of the diagnosis, life continues with daily changes, the feelings of despair and fear are appeased over time, however prejudice persists. Conclusion: The results show a complex scenario of (con) living with the virus and / or the syndrome. The discovery of diagnosis, acceptance, decision on disclosure, gathering means to face prejudice and continue living, requires that PLHIV have support and reprogram themselves to face daily challenges.

ABSTRACT

Pleomorphic adenoma is a benign neoplasm of the salivary glands that affects most frequently females in the fourth and sixth decade of life. As it is usually an asymptomatic lesion, it is diagnosed upon routine physical examination. Treatment consists in surgical removal with partial or total involvement of the parotid gland. Conservative enucleation is the least invasive surgical option for this type of lesion. The present work aimed to report a case of pleomorphic adenoma of the parotid gland with eight years of evolution. The tumor was treated conservatively. Patient has been followed for sixth months, and no sensory alterations, fistulae, clinical signs of recurrence, nor any other alteration have been observed so far. Due to the benign nature of the lesion, an evolution with favorable prognosis is expected. (AU)


O Adenoma pleomórfico é uma neoplasia benigna de glândulas salivares, que acomete com maior frequência pessoas do sexo feminino entre a quarta e sexta década de vida. Por se tratar de uma lesão muitas vezes assintomática, geralmente é descoberta através do exame físico de rotina. O seu tratamento consiste em remoção cirúrgica podendo envolver ou não a glândula parótida de maneira parcial ou total. A enucleação conservadora é a modalidade cirúrgica menos invasiva para este tipo de lesão. O presente trabalho tem por objetivo relatar um caso de adenoma pleomórfico em glândula parótida com oito anos de evolução. O tumor foi tratado de maneira conservadora. A paciente está sendo acompanhada há 6 meses e não foram observados até momento alterações sensoriais, fistulas, indícios clínicos de recidiva ou qualquer outra alteração. Devido ao caráter benigno da lesão, espera-se evolução com prognóstico favorável. (AU)

ABSTRACT

Introdução: As Unidades de Pronto Atendimento (UPAs) funcionam como porta de entrada para os casos de urgência e emergência e, muitas vezes, para casos de caráter não emergencial. Objetivo: Identificar o conhecimento da população a respeito dos serviços prestados pelas UPAs em Curitiba-PR. Método: Estudo observacional transversal, avaliou 516 pessoas que estavam em espera para atendimento nas UPAs, com classificação não urgente ou pouco urgente, segundo Protocolo Internacional de Manchester. A coleta se deu por meio de questionário semiestruturado aplicado por entrevistador. Resultados: 82,8% dos entrevistados acreditavam estar no local correto para o seu atendimento, fator que foi independente estatisticamente da escolaridade ou do conhecimento sobre as Unidades Básicas de Saúde (UBS); 86,6% dos usuários foram à UPA por busca direta, e uma parcela de 24,9% cogitou ir a uma UBS antes. Dentre os motivos mais frequentes de procura pela UPA, em ordem decrescente, abrangiam questões de locomoção, desconhecimento do funcionamento do sistema de saúde, motivos pessoais, a não necessidade de marcar consulta e, por fim, considerar a própria doença como grave. Conclusão: Existe a necessidade de se fortalecer o vínculo do usuário com as UBS, assim como uma melhor estruturação da atenção primária.


Introduction: Emergency Care Units (ECU) work as a gateway for urgent and emergency cases and, often, also for non-emergency ones. Objective: Identification of the knowledge of the population regarding the services provided by the ECU in Curitiba-PR. Method: A cross-sectional observational study evaluated 516 people who were waiting for care in the ECU, classified as non-urgent or of little urgency, according to the Manchester International Protocol. Data collection occurred through a semi-structured questionnaire applied by an interviewer. Results: 82.8% of the interviewees believed they were in the correct place for their care, a factor that was statistically independent of schooling or knowledge about Basic Health Units (BHU); 86.6% of users went to the ECU by direct search, and 24.9% of users considered going to a BHU before. Among the most frequent reasons for going to the ECU, in decreasing order, ranged from locomotion, lack of knowledge about the operation of the health system, personal reasons, the possibility of just walking in, without the need to make an appointment and, finally, the fact that they considered the illness severe. Conclusion: There is a need to strengthen the user's bond with the BHU and consequently better structuring of primary care.

ABSTRACT

Abstract This study investigated the effects of oxygen inhibition and finishing/polishing procedures on the composite resin properties. One bulk-fill and two conventional composite resins (nanoparticle and microhybrid) were evaluated. Specimens were prepared using 4 surface treatments: control, no treatment; Gly, oxygen inhibition with glycerin; FP, finishing and polishing; Gly + FP, glycerin followed by finishing and polishing. The degree of conversion (DC) was measured using Fourier Transformed Infrared Spectroscopy (FTIR) immediately and after 15 days (n=5). Color stability (ΔEab, and ΔE00) and opacity were evaluated using a spectrophotometer after 15 days of immersion in coffee, using the CIELAB system (n=5). Data were analyzed by two-way ANOVA and Tukey tests (α=0.05) and opacity by two-way repeated-measures ANOVA. Glycerin usage increased significantly the DC however had no influence on the ΔEab, ΔE00 and, opacity values. Finishing and polishing reduced ΔEab and ΔE00 values, regardless of composite resins. Microhybrid showed higher opacity, followed by the nanoparticle and bulk fill, regardless of surface treatment. Post-polymerization polishing procedures resulted in lower conversion than using an oxygen inhibitor agent (Gly condition), but similar staining caused by coffee.


Resumo Este estudo investigou os efeitos da inibição de oxigênio e dos procedimentos de acabamento/polimento nas propriedades das resinas compostas. Foram avaliadas uma resina composta bulk fill e duas resinas convencionais (nanoparticulada e microhíbrida). Os espécimes foram confeccionados, variando o tratamento de superfície: controle, sem tratamento; glicerina (inibidor de oxigênio); acabamento e polimento; glicerina + acabamento e polimento. O grau de conversão (GC) foi medido pela Espectroscopia de Infravermelho Transformada de Fourier (FTIR) imediatamente e após 15 dias da confecção dos espécimes (n=5). Os índices de alteração de cor ΔEab, ΔE00 e opacidade foram avaliados por meio de espectrofotômetro, após 15 dias de imersão no café, utilizando o sistema CIELAB (n=5). Os dados da alteração da cor foram analisados pelos testes ANOVA de dois fatores e Tukey (α=0,05) e a opacidade por ANOVA de medidas repetidas. O uso de glicerina aumentou significativamente o GC, no entanto, não teve influência sobre os valores ΔEab e ΔE00. O acabamento e o polimento reduziram os valores de ΔEab e ΔE00, independentemente da resina composta. A resina microhíbrida apresentou maior opacidade, seguida pela nanoparticula e bulk-fill, independentemente do tratamento de superfície. O acabamento e polimento resultou em menor grau de conversão das resinas compostas se comparado ao uso de um agente inibidor de oxigênio (glicerina), porém apresenta resultados similares para a pigmentação pelo café.

ABSTRACT

Abstract Objective To evaluate the effect of the association between external and internal tooth bleaching on color changes in dentin and enamel, individually or recombined, previously stained with triple antibiotic paste (TAP). Methodology Forty enamel-dentin specimens from bovine incisors were separated into ten blocks according to similarity in their whiteness index (WID). Three specimens within each block were stained by dentin exposure to TAP, and the remaining specimen was used as control to estimate color changes. Specimens were sectioned to separate tissues, and dentin and enamel colors were measured individually and after being recombined. Alterations in color (CIEDE2000 - ΔE00) and translucency parameter (TP) resulting from staining were estimated by color difference between stained and control specimens. The contribution of each tissue to the color change (CTCC) was also calculated. Non-sectioned stained specimens were bleached by applying sodium perborate on dentin, associated or not with 35% hydrogen peroxide on enamel. Color changes caused by bleaching procedures were estimated and data were analyzed using the paired t-test or Two-way repeated measures ANOVA. Results TAP caused more pronounced changes in dentin, but enamel color was also affected. Both protocols presented a similar ΔE00, and dentin showed the greater color change. After exposure to TAP, we observed a reduction in WID; WID values were the same for bleached and control specimens regardless of protocol. We found no significant effect of substrate and bleaching technique on TP. Enamel played a more critical role in color changes caused by either staining or bleaching procedures. Conclusion Enamel color played a greater role on tooth color changes than dentin. External and internal bleaching association did not improve bleaching effect on specimens stained with TAP.

ABSTRACT

abstract - This study aimed to identify the prevalence of excess body weight in university students from a representative state in Brazil's southern region and establish associations with the demographic, university environment, and health behavior correlates. A random sample of 5,310 university students answered an online questionnaire with demographic, university environment, and eight health behavior data. Excess body weight was identified using the body mass index (BMI ≥ 25 kg/m2). The data were processed using bivariate analysis and hierarchical multiple regression. The overall prevalence of excess body weight exposure was equivalent to 39.1% [35.7-42.6], with significantly different rates between gender, age, and marital status. Likewise, housing type and study year showed significant associations with excess body weight. Among health behavior indicators, with control of all other variables involved in the model, depressive symptoms (p = 0.031), high stress (p = 0.045), sleep duration < 6 hours/night (p < 0.001), moderate-vigorous physical activity < 150 min/week (p = 0.022) and fruit/vegetable consumption < 5 servings per day (p < 0.001) were independently associated with the outcome. However, tobacco use, binge drinking, and prescription drug misuse did not remain in the adjusted multivariate model. In conclusion, the findings emphasize the importance of proposing and implementing multifaceted preventive intervention actions to prevent health outcomes related to excess body weight, once since significant associations with modifiable factors have been identified.


resumo O objetivo do estudo foi identificar a prevalência do excesso de peso corporal em estudantes universitários de um estado representativo da região sul do Brasil e estabelecer associações com correlatos demográficos, do ambiente universitário e de condutas de saúde. Amostra aleatória de 5310 estudantes universitários respondeu questionário online com dados demográficos, do ambiente universitário e de oito condutas de saúde. O excesso de peso corporal foi identificado mediante o índice de massa corporal (IMC ≥ 25 Kg/m2). Os dados foram tratados através de análise bivariada e regressão múltipla hierarquizada. Prevalência global de exposição ao excesso de peso corporal foi equivalente a 39,1% [35,7-42,6], com taxas significativamente diferentes entre sexo, idade e situação conjugal. Da mesma forma, tipo de habitação e ano de estudo apresentaram associações significativas com o excesso de peso corporal. Entre os indicadores de conduta de saúde, com controle de todas as demais variáveis envolvidas no modelo, sintomas de depressão (p = 0,031), estresse elevado (p = 0,045), duração de sono < 6 horas/noite (p < 0,001), atividade física moderada-vigorosa < 150 min/semana (p = 0,022) e consumo de frutas/hortaliças < 5 porções/dias (p < 0,001) mostraram-se independentemente associados ao desfecho. Contudo, tabagismo, consumo nocivo de álcool e uso indevido de medicamentos controlados não permaneceram no modelo multivariado ajustado. Concluindo, os achados enfatizam a importância de propor e implementar ações de intervenção preventivas multifacetadas a fim de prevenir agravos relacionados ao excesso de peso corporal, uma vez identificada associações significativas com fatores modificáveis.
