Abstract This integrative review aims to identify the mental health care measures that were produced during the COVID-19 pandemic. This research was conducted on three databases (SciELO, PubMed, and LILACS) with the following descriptors in Portuguese, English, and Spanish: “SAÚDE MENTAL” or “SALUD MENTAL” or “MENTAL HEALTH” AND “COVID-19” from 2020 to 2021. In total, 3,451 articles were found, 43 of which were analyzed. Most measures were digital, stemmed from public institutions, focused on the local perspective, and were integrated with the public health care system. This study discusses the models of care in mental health based on measures to cope with the COVID-19 pandemic. It also discusses the Brazilian health care system, reiterating its resilience. In conclusion, digital measures occurred most often. This study suggest the evaluation of the accessibility of this mental health care model for most vulnerable groups. Finally, this research reinforces the importance of the Brazilian health care system for public health and access to information to cope with the COVID-19 pandemic.

ABSTRACT The hydrodynamic conditions to which hydraulic structures such as spillways and stilling basins of dams are submitted under given conditions favor the occurrence of cavitation, damaging the concrete surfaces. This damage may be intensified by the cumulative effect of the successive hydrologic events that characterize the operational regime of these structures. Thus, the purpose of the present article is to identify the propensity for damage caused by cavitation by using SpillwayPro software to estimate the hydraulic parameters of flow (mean velocities and cavitation indices) based on information on smooth chute spillways at the Furnas, Luiz Carlos Barreto de Carvalho and Batalha hydroelectric power plants. The results shown were compared to the critical limits of cavitation defined in the literature on photographic records of inspections performed in the field. The highest mean velocities estimated coincided with the zones where the worst potential damage of the structures was identified. Nevertheless, most of the cavitation indices obtained did not present results similar to the limits presented by different authors, and thus do not favor the indication of cavitation risks due to this parameter in the spillways examined. surfaces Thus Furnas plants field identified Nevertheless authors examined

ABSTRACT: Leptospirosis, a disease of significant economic impact on livestock and public health concern, may exhibit unique epidemiological characteristics in indigenous villages, particularly those located within semiarid climates such as the Caatinga biome in Brazil. This environment often presents conditions unfavorable for leptospire survival. This study conducted serological diagnoses of livestock in indigenous villages within the Caatinga biome, Northeastern Brazil. The survey was carried out in the Mãe Maria and Santa Helena indigenous villages, home to the Xukuru de Cimbres tribe, in the county of Pesqueira, Pernambuco State, Brazil, within the Caatinga biome. Blood samples were collected from cattle (n = 42), goats (n = 41), and sheep (n = 19). Out of the 102 samples tested, 73 (71.6%; 95% CI = 62.8% - 80.3%) were seroreactive (cut-off ≥ 100). The seropositivity rates for cattle, goats, and sheep were 54.8%, 80.5%, and 89.5%, respectively. A statistically significant difference was observed in the proportion of seropositive animals between cattle and goats and cattle and sheep (P < 0.05). Icterohaemorrhagiae was identified as the most probable serogroup across all animal species. The study revealed that livestock in indigenous villages within the Caatinga biome are frequently exposed to leptospires. This finding underscores the importance of a One Health approach, emphasizing the need for comprehensive studies in areas where large human and animal populations coexist. Such studies are crucial for investigating zoonotic infections and for planning and implementing control measures against livestock-associated leptospirosis.

RESUMO: A leptospirose causa perdas econômicas na pecuária e é um problema de saúde pública, sendo possível que existam peculiaridades na epidemiologia dessa doença em aldeias indígenas, principalmente naquelas de áreas de clima semiárido, como o bioma Caatinga no Nordeste do Brasil, onde o ambiente é frequentemente adverso à sobrevivência de leptospiras. Assim, o objetivo deste estudo foi realizar o diagnóstico sorológico em rebanhos de aldeias indígenas no bioma Caatinga. A pesquisa foi realizada nas aldeias indígenas Mãe Maria e Santa Helena, tribo Xukuru de Cimbres, município de Pesqueira, estado de Pernambuco, Brasil, dentro do bioma Caatinga. Amostras de sangue foram colhidas de bovinos (n = 42), caprinos (n = 41) e ovinos (n = 19). No geral, das 102 amostras testadas 73 (71,6%; IC 95% = 62,8% - 80,3%) foram sororreativas (ponto de corte ≥ 100). Para bovinos, caprinos e ovinos as taxas de soropositividade foram de 54,8%, 80,5% e 89,5%, respectivamente. Houve diferença estatística na proporção de animais soropositivos entre bovinos e caprinos e bovinos e ovinos (P < 0,05). Icterohaemorrhagiae foi o sorogrupo mais provável em todas as espécies animais. O estudo mostra que animais de produção de aldeias indígenas são comumente expostos a leptospiras no bioma Caatinga, o que constitui uma preocupação do ponto de vista de Saúde Única e demonstra a importância de estudos amplos em que coexistem grandes números de humanos e animais na investigação de infecções zoonóticas e no planejamento e implementação de medidas de controle da leptospirose associada a animais de produção.

ABSTRACT Purpose: The prevalence of ocular allergy varies according to the population and location of the study. Severe forms of ocular allergy are associated with compromised quality of life. In this study, we aimed to evaluate the application of the Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire to children and adolescents with different subtypes of allergic conjunctivitis. Method: A total of 48 patients (aged 5-12 years) with allergic conjunctivitis were included in this study. They were enrolled and monitored at a specialized center. After the clinical appointment, the children responded to the questionnaire on two occasions at an interval of 30 days. Individual scores (ranging from 0 to 3) of the 16 items were added. Results: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire demonstrated good translation, adaptation, and intellectual properties, with substantial internal consistency (Cronbach’s α coefficient = 0.702). There was no significant difference between the responses of the two interviews, revealing good reproducibility. The moderate/severe forms of allergic conjunctivitis had significantly higher quality of life scores (indicating a poorer quality of life) than the mild forms. Conclusions: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis proved to be quick, reliable, and reproducible for assessing the quality of life in children with allergic conjunctivitis. However, its ability to detect changes resulting from symptom aggravation or treatment needs to be further evaluated.

ABSTRACT Objectives: To analyze brain death (BD) notifications received by Central de Transplantes (CET) in the state of Roraima (RR) from 2017 to 2021. Methods: This is a cross-sectional, quantitative, and observational study, where all notifications received by CET from 2017 to 2021 were analyzed, resulting in 120 patients from health the following centers: Hospital Geral de Roraima (HGR), Hospital Confederação Nacional das Cooperativas Médicas (UNIMED), Hospital da Criança Santo Antônio (HCSA), Hospital das Clínicas (HC), and Hospital Lotty Íris (HLI). The data were collected from the center’s data management system and passed on to the collection form developed by the researcher. Results: This study analyzed 119 notifications after excluding one due to conflicting data. There was a predominance of males (58%), with traumatic brain injury being the most frequent cause of BD. Six organ harvestings were carried out, all at the HGR. This study found no significant associations between organ procurement and sex, age, place of hospitalization, and year. Conclusion: There are considerable challenges concerning organ donation in RR, with a low uptake rate over five years. Only the HGR successfully carried out organ harvesting, while other reporting hospitals were unsuccessful. Improvements are needed, highlighting the importance of more studies for a more in-depth data analysis.

RESUMO Objetivos: Analisar as notificações de morte encefálica (ME) recebidas pela Central de Transplantes (CET) do estado de Roraima (RR) de 2017 a 2021. Métodos: Trata-se de estudo transversal, quantitativo e observacional no qual foram analisadas todas as notificações recebidas pela CET no período de 2017 a 2021, resultando em 120 pacientes, dos seguintes centros de saúde: Hospital Geral de Roraima (HGR), Hospital Confederação Nacional das Cooperativas Médicas (UNIMED), Hospital da Criança Santo Antônio (HCSA), Hospital das Clínicas (HC) e Hospital Lotty Íris (HLI). Os dados foram coletados do sistema de gerenciamento de dados da central e repassados para a ficha de coleta desenvolvida pela pesquisadora. Resultados: Este estudo analisou 119 notificações após a exclusão de uma devido a dados conflitantes. Houve predominância do sexo masculino (58%), com trauma cranioencefálico sendo a causa mais frequente de ME. Ao todo, foram realizadas seis captações de órgãos, todas no HGR. Este estudo não encontrou associações significativas entre a captação de órgãos e sexo, idade, local de internação e ano. Conclusão: Há grandes desafios em relação à doação de órgãos em RR, com uma taxa de captação baixa ao longo de 5 anos. Apenas o HGR obteve sucesso em realizar captações de órgãos, diferentemente de outros hospitais notificadores. São necessárias melhorias, destacando a importância de se realizarem mais estudos para uma análise mais aprofundada dos dados.

ABSTRACT Background: Driving pressure has been suggested to be the main driver of ventilator-induced lung injury and mortality in observational studies of acute respiratory distress syndrome. Whether a driving pressure-limiting strategy can improve clinical outcomes is unclear. Objective: To describe the protocol and statistical analysis plan that will be used to test whether a driving pressure-limiting strategy including positive end-expiratory pressure titration according to the best respiratory compliance and reduction in tidal volume is superior to a standard strategy involving the use of the ARDSNet low-positive end-expiratory pressure table in terms of increasing the number of ventilator-free days in patients with acute respiratory distress syndrome due to community-acquired pneumonia. Methods: The ventilator STrAtegy for coMmunIty acquired pNeumoniA (STAMINA) study is a randomized, multicenter, open-label trial that compares a driving pressure-limiting strategy to the ARDSnet low-positive end-expiratory pressure table in patients with moderate-to-severe acute respiratory distress syndrome due to community-acquired pneumonia admitted to intensive care units. We expect to recruit 500 patients from 20 Brazilian and 2 Colombian intensive care units. They will be randomized to a driving pressure-limiting strategy group or to a standard strategy using the ARDSNet low-positive end-expiratory pressure table. In the driving pressure-limiting strategy group, positive end-expiratory pressure will be titrated according to the best respiratory system compliance. Outcomes: The primary outcome is the number of ventilator-free days within 28 days. The secondary outcomes are in-hospital and intensive care unit mortality and the need for rescue therapies such as extracorporeal life support, recruitment maneuvers and inhaled nitric oxide. Conclusion: STAMINA is designed to provide evidence on whether a driving pressure-limiting strategy is superior to the ARDSNet low-positive end-expiratory pressure table strategy for increasing the number of ventilator-free days within 28 days in patients with moderate-to-severe acute respiratory distress syndrome. Here, we describe the rationale, design and status of the trial.

RESUMO Contexto: Em estudos observacionais sobre a síndrome do desconforto respiratório agudo, sugeriu-se que a driving pressure é o principal fator de lesão pulmonar induzida por ventilador e de mortalidade. Não está claro se uma estratégia de limitação da driving pressure pode melhorar os desfechos clínicos. Objetivo: Descrever o protocolo e o plano de análise estatística que serão usados para testar se uma estratégia de limitação da driving pressure envolvendo a titulação da pressão positiva expiratória final de acordo com a melhor complacência respiratória e a redução do volume corrente é superior a uma estratégia padrão envolvendo o uso da tabela de pressão positiva expiratória final baixa do protocolo ARDSNet, em termos de aumento do número de dias sem ventilador em pacientes com síndrome do desconforto respiratório agudo devido à pneumonia adquirida na comunidade. Métodos: O estudo STAMINA (ventilator STrAtegy for coMmunIty acquired pNeumoniA) é randomizado, multicêntrico e aberto e compara uma estratégia de limitação da driving pressure com a tabela de pressão positiva expiratória final baixa do protocolo ARDSnet em pacientes com síndrome do desconforto respiratório agudo moderada a grave devido à pneumonia adquirida na comunidade internados em unidades de terapia intensiva. Esperamos recrutar 500 pacientes de 20 unidades de terapia intensiva brasileiras e duas colombianas. Eles serão randomizados para um grupo da estratégia de limitação da driving pressure ou para um grupo de estratégia padrão usando a tabela de pressão positiva expiratória final baixa do protocolo ARDSnet. No grupo da estratégia de limitação da driving pressure, a pressão positiva expiratória final será titulada de acordo com a melhor complacência do sistema respiratório. Desfechos: O desfecho primário é o número de dias sem ventilador em 28 dias. Os desfechos secundários são a mortalidade hospitalar e na unidade de terapia intensiva e a necessidade de terapias de resgate, como suporte de vida extracorpóreo, manobras de recrutamento e óxido nítrico inalado. Conclusão: O STAMINA foi projetado para fornecer evidências sobre se uma estratégia de limitação da driving pressure é superior à estratégia da tabela de pressão positiva expiratória final baixa do protocolo ARDSnet para aumentar o número de dias sem ventilador em 28 dias em pacientes com síndrome do desconforto respiratório agudo moderada a grave.

Abstract The aim of this study was to evaluate the impact of oral conditions and health-related quality of life (HRQoL) on oral health-related quality of life (OHRQoL) in children and adolescents with blood coagulation disorders and hemoglobinopathies (BCDH). The study was cross-sectional and included 61 individuals aged 2 to 18 years with BCDH. Exams for dental caries (dmft/DMFT index), oral hygiene (simplified oral hygiene index – OHI-S), and gingival health (modified gingival index – MGI) were performed. The pediatric quality of life inventory™ (PedsQL™) generic core scale and oral health scale were used to measure HRQoL and OHRQoL. Spearman’s correlation coefficient (ρ) and the Mann-Whitney test (α = 0.05) were conducted to assess the relationship between covariates and the PedsQL™ oral health scale. The mean PedsQL™ oral health scale score was 76.66 (SD = 21.36). Worse OHRQoL was correlated with poor oral hygiene (ρ = -0.383; p: 0.004), poor gingival health (ρ = -0.327; p = 0.014), and better HRQoL (ρ = 0.488; p < 0.001). Greater untreated dental caries experience was associated with worse OHRQoL (p = 0.009). Worse oral health status in children and adolescents with BCDH negatively impacts OHRQoL, and OHRQoL and quality of life analyzed from a generic perspective are positively correlated constructs in this population. healthrelated related (HRQoL (OHRQoL .

ABSTRACT In ecotonal Cerrado areas, the addition of Amazonian and Atlantic Forest species mainly occurs through connections between forest areas and forest physiognomies. In this context, the biome is a unique region for research on the influence of geographical and historical factors on its biota. In tropical ecotonal regions, integrated communities can exist on soils that present variations in fertility, physical properties and depth, which results in heterogeneity of physiognomies. It was tested the hypothesis that edaphic conditions related to calcium availability are significantly related to species composition and structural parameters in two physiognomies. The study was conducted in the Cerrado of the Chapada das Mesas National Park (CMNP) in the city of Carolina, Northeast Brazil, and the sample universe consisted of 18 areas in two physiognomies. The initial hypothesis was confirmed. The results and inferences about the vegetation structure and physical-chemical parameters of the soil, suggest that the management for conservation of the CMNP must consider the particularities of the Cerrado physiognomies and the vegetation responses to environmental filters, such as edaphic conditions and associations with other organisms. context biota regions fertility depth (CMNP Carolina Brazil 1 confirmed physicalchemical chemical soil filters organisms

ABSTRACT Objective: To evaluate the association of TSH, free T3 (FT3), free T4 (FT4), and conversion (FT3:FT4) ratio values with incident hypertension. Materials and methods: The study included data from participants of the ELSA-Brasil study without baseline hypertension. Serum TSH, FT4 and FT3 levels, and FT3:FT4 ratio values were assessed at baseline, and incident hypertension (defined by blood pressure levels ≥ 140/90 mmHg) was estimated over a median of 8.2 years of follow-up. The risk of incident hypertension was evaluated considering a 1-unit increase in TSH, FT4, FT3, and conversion ratio values and after dividing these variables into quintiles for further analysis using Poisson regression with robust variance. The results are presented as relative risks (RR) and 95% confidence intervals (CIs) before and after adjustment for multiple variables. Results: The primary analysis incorporated data from 5,915 euthyroid individuals, and the secondary analysis combined data from all euthyroid individuals, 587 individuals with subclinical hypothyroidism, and 31 individuals with subclinical hyperthyroidism. The rate of incident hypertension was 28% (95% CI: 27%-29.3%). The FT4 levels in the first quintile (0.18-1.06 ng/dL) were significantly associated with incident hypertension (RR: 1.03, 95% CI: 1.01-1.06) at follow-up. The association between FT4 levels in the first quintile and incident hypertension was also observed in the analysis of combined data from euthyroid individuals and participants with subclinical thyroid dysfunction (RR: 1.04, 95% CI: 1.01-1.07). The associations were predominantly observed with systolic blood pressure levels in euthyroid individuals. However, in the combined analysis incorporating euthyroid participants and individuals with subclinical thyroid dysfunction, the associations were more pronounced with diastolic blood pressure levels. Conclusion: Low FT4 levels may be a mild risk factor for incident hypertension in euthyroid individuals and persons with subclinical thyroid dysfunction.

ABSTRACT This study aimed to identify factors associated with colonization by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in adult patients admitted to a Brazilian hospital. This is a cross-sectional study, in which patients underwent a nasal swab and were asked about hygiene behavior, habits, and clinical history. Among the 702 patients, 180 (25.6%) had S. aureus and 21 (2.9%) MRSA. The factors associated with MRSA colonization were attending a gym (OR 4.71; 95% CI; 1.42 – 15.06), smoking habit in the last year (OR 2.37; 95% CI; 0.88 – 6.38), previous hospitalization (OR 2.18; CI 95%; 0.89 – 5.25), and shared personal hygiene items (OR 1.99; 95% CI; 0.71 – 5.55). At the time of admission, colonization by CA-MRSA isolates was higher than that found in the general population. This can be an important public health problem, already endemic in hospitals, whose factors such as those associated with habits (smoking cigarettes) and behaviors (team sports practice and activities in gyms) have been strongly highlighted. These findings may help developing infection control policies, allowing targeting patients on higher-risk populations for MRSA colonization. communityassociated community methicillinresistant methicillin resistant CAMRSA CA (CA-MRSA hospital crosssectional cross sectional behavior history 70 18 25.6% 256 25 6 (25.6% S 2 2.9% 29 9 (2.9% OR 4.71 471 4 71 95 142 1 42 1.4 15.06, 1506 15.06 , 15 06 15.06) 2.37 237 37 088 0 88 0.8 6.38, 638 6.38 38 6.38) 2.18 218 089 89 5.25, 525 5.25 5 5.25) 1.99 199 99 071 0.7 5.55. 555 5.55 . 55 5.55) admission population problem hospitals cigarettes team gyms highlighted policies higherrisk risk 7 25.6 (25.6 2.9 (2.9 4.7 47 14 1. 150 15.0 2.3 23 3 08 8 0. 63 6.3 2.1 52 5.2 1.9 19 07 5.5 25.

Resumo A radiologia tem uma série de características que a torna uma disciplina médica especialmente adequada à adoção precoce da inteligência artificial (IA), incluindo um fluxo de trabalho digital bem estabelecido, protocolos padronizados para armazenamento de imagens e inúmeras atividades interpretativas bem definidas. Tal adequação é corroborada pelos mais de 200 produtos radiológicos comerciais baseados em IA recentemente aprovados pelo Food and Drug Administration (FDA) para auxiliar os radiologistas em uma série de tarefas restritas de análise de imagens, como quantificação, triagem de fluxo de trabalho e aprimoramento da qualidade das imagens. Entretanto, para o aumento da eficácia e eficiência da IA, além de uma utilização clínica bem-sucedida dos produtos que utilizam essa tecnologia, os radiologistas devem estar atualizados com as aplicações em suas áreas específicas de atuação. Assim, neste artigo, pesquisamos na literatura existente aplicações baseadas em IA em neurorradiologia, mais especificamente em condições como doenças vasculares, epilepsia, condições desmielinizantes e neurodegenerativas. Também abordamos os principais algoritmos por trás de tais aplicações, discutimos alguns dos desafios na generalização no uso desses modelos e introduzimos as soluções comercialmente disponíveis mais relevantes adotadas na prática clínica. Se cautelosamente desenvolvidos, os algoritmos de IA têm o potencial de melhorar radicalmente a radiologia, aperfeiçoando a análise de imagens, aumentando o valor das técnicas de imagem quantitativas e mitigando erros de diagnóstico. , (IA) estabelecido definidas 20 FDA (FDA quantificação Entretanto bemsucedida sucedida tecnologia atuação Assim artigo neurorradiologia vasculares epilepsia neurodegenerativas desenvolvidos diagnóstico (IA 2

Abstract Radiology has a number of characteristics that make it an especially suitable medical discipline for early artificial intelligence (AI) adoption. These include having a well-established digital workflow, standardized protocols for image storage, and numerous well-defined interpretive activities. The more than 200 commercial radiologic AI-based products recently approved by the Food and Drug Administration (FDA) to assist radiologists in a number of narrow image-analysis tasks such as image enhancement, workflow triage, and quantification, corroborate this observation. However, in order to leverage AI to boost efficacy and efficiency, and to overcome substantial obstacles to widespread successful clinical use of these products, radiologists should become familiarized with the emerging applications in their particular areas of expertise. In light of this, in this article we survey the existing literature on the application of AI-based techniques in neuroradiology, focusing on conditions such as vascular diseases, epilepsy, and demyelinating and neurodegenerative conditions. We also introduce some of the algorithms behind the applications, briefly discuss a few of the challenges of generalization in the use of AI models in neuroradiology, and skate over the most relevant commercially available solutions adopted in clinical practice. If well designed, AI algorithms have the potential to radically improve radiology, strengthening image analysis, enhancing the value of quantitative imaging techniques, and mitigating diagnostic errors.

RESUMO Objetivo: Analisar as coberturas vacinais (CV) da poliomielite nos municípios do Vale do Paraíba paulista. Métodos: Trata-se de um estudo ecológico e exploratório de CV em 35 municípios com abordagem espacial. Os dados de CV foram obtidos do Departamento de Informática do Sistema Único de Saúde (DATASUS), referentes aos anos de 2015 e 2019 e categorizados em baixa (CV<95%) e ideal (≥95%). Foram obtidas informações sobre Produto Interno Bruto (PIB), taxas de profissionais, número de unidades básicas de saúde (UBS) e dados maternos como idade, estado civil (EC) e escolaridade. Foram estimados índices de Moran univariados e bivariados para os anos de 2015 e 2019 e criados mapas temáticos para valores de CV. Resultados: Os valores médios de CV foram de 107,7%±27,2 em 2015 e 94,2%±27,8 em 2019 (p<0,05). Em 2015, eram dez municípios na categoria baixa e, em 2019, eram 25 municípios. Em 2015, as variáveis CV, número de UBS, idade, escolaridade e situação marital foram correlacionadas espacialmente, mas em 2019 apenas idade materna e escolaridade foram correlacionadas espacialmente. O Moran bivariado foi significativo e negativo para CV em 2019 com escolaridade materna. Houve aumento de municípios com piora nos valores de CV. Conclusões: A abordagem espacial identificou diminuição da cobertura vacinal contra a poliomielite na região estudada.

ABSTRACT Objective: To analyze vaccination coverage (VC) for polio in the municipalities of Vale do Paraíba in the State of São Paulo. Methods: This is an ecological and exploratory study of VC in 35 municipalities using a spatial approach; VC data were obtained from the IT Department of the Unified Health System (DATASUS), for the years 2015 and 2019, and categorized into Low (VC<95%) and ideal (≥95%). Information was obtained on gross domestic product (GDP), professional rates and number of basic health units (UBS) and maternal data such as age, marital status (MS) and education. Univariate and bivariate Moran indices were estimated for the years 2015 and 2019, and thematic maps were created for CV values. Results: The average VC values were 107.7%±27.2 in 2015, and 94.2%±27.8 in 2019 (p<0.05). In 2015 vs. 2019, there were 10 vs. 25 municipalities in the Low category. In 2015, the variables VC, number of UBS, age, education, and MS were spatially correlated, but in 2019 only maternal age and education were spatially correlated. The bivariate Moran was significant and negative for VC in 2019 with maternal education. There was an increase in municipalities with worsening VC values. Conclusions: The spatial approach identified a decrease in polio vaccination coverage in the studied region.

Abstract This study aimed to assess the influence of streptozotocin (STZ)-induced diabetes on the nociceptive behavior evoked by the injection of hypertonic saline (HS) into the masseter muscle of rats. Forty male rats were equally divided into four groups: a) isotonic saline control, which received 0.9% isotonic saline (IS), (Ctrl-IS); b) hypertonic saline control, which received 5% HS (Ctrl-HS); c) STZ-induced diabetic, which received IS, (STZ-IS); d) STZ-induced diabetic, which received HS (STZ-HS). Experimental diabetes was induced by a single intraperitoneal injection of STZ at dose of 60 mg/kg dissolved in 0.1 M citrate buffer, and 100 μL of HS or IS were injected into the left masseter to measure the nociceptive behavior. Later on, muscle RNA was extracted to measure the relative expression of the following cytokines: cyclooxygenase-2 (COX-2), tumor necrosis factor (TNF-α), and interleukins (IL)-1β, -2, -6, and -10. One-way analysis of variance (ANOVA) was applied to the data (p < 0.050). We observed a main effect of group on the nociceptive response (ANOVA: F = 11.60, p < 0.001), where the Ctrl-HS group presented the highest response (p < 0.001). However, nociceptive response was similar among the Ctrl-IS, STZ-IS, and STZ-HS group (p > 0.050). In addition, the highest relative gene expression of TNF-α and IL-6 was found in the masseter of control rats following experimental muscle pain (p < 0.050). In conclusion, the loss of somatosensory function can be observed in deep orofacial tissues of STZ-induced diabetic rats.

Abstract Introduction The non-carious degradation of the dentin matrix is a natural process throughout life; however, when associated with the presence of excessive acidic substances, it leads to lesions in dental structures. Objective This study developed an experimental solution based on antioxidant polyphenols from the yellow passion fruit seed (Passiflora edulis) and assessed its preventive potential on eroded dentin. The experimental polyphenolic solution was obtained from passion fruit seeds through drying and cold pressing. Material and method Thirty samples of bovine cervical root dentin were acquired and randomized into three groups (n=10): G1 – distilled water; G2 – experimental solution of phenolic antioxidants from passion fruit; G3 – Commercial anti-erosion toothpaste. Erosive cycling and treatment were conducted over 3 days. Subsequently, non-contact 3D confocal microscopy was employed to measure volumetric (Sa) and linear (Ra) roughness, as well as erosive wear. A one-way ANOVA/Tukey test was performed (α=0.05). Result The G2 group had lower Ra and Sa values compared to the other groups and demonstrated the lowest erosive wear in µm compared to G1 and G3. Conclusion: The experimental solution based on antioxidant polyphenols from Passiflora edulis showed promising performance on eroded dentin in this investigation. Nevertheless, further research is required to establish its effectiveness and potential use in developing a new product. noncarious non carious life however substances structures pressing n=10 n10 n 10 (n=10) G water antierosion anti erosion toothpaste days Subsequently noncontact contact D (Sa (Ra roughness oneway one way ANOVATukey ANOVA Tukey α=0.05. α005 α α=0.05 . 0 05 (α=0.05) Conclusion investigation Nevertheless product n=1 n1 1 (n=10 α00 α=0.0 (α=0.05 n= (n=1 α0 α=0.

Resumo Introdução A degradação não-cariosa da matriz dentinária é um processo natural ao longo da vida; no entanto, quando associada à presença de substâncias ácidas excessivas, leva a lesões nas estruturas dentárias. Objetivo Este estudo desenvolveu uma solução experimental baseada em polifenóis antioxidantes da semente do maracujá amarelo (Passiflora edulis) e avaliou seu potencial preventivo sobre a dentina erodida. A solução polifenólica experimental foi obtida a partir de sementes de maracujá através de secagem e prensagem a frio. Material e método Trinta amostras de dentina radicular cervical bovina foram adquiridas e randomizadas em três grupos (n=10): G1 – água destilada; G2 – solução experimental de antioxidantes fenólicos do maracujá; G3 – pasta de dente comercial anti-erosão. Ciclos erosivos e tratamento foram conduzidos ao longo de 3 dias. Posteriormente, microscopia confocal 3D sem contato foi empregada para medir a rugosidade volumétrica (Sa) e linear (Ra), bem como o desgaste erosivo. Um teste ANOVA/Tukey de uma via foi realizado (α=0,05).
