Resumo Objetivos: Avaliar a anatomia do ducto nasolacrimal e a espessura do osso maxilar adjacente por meio de tomografia computadorizada multislice. Métodos: Imagens tomográficas de 92 indivíduos (184 lados) foram analisadas quanto ao sexo, lado e padrão esquelético sagital (Classe I, II e III) e vertical (mesocefálico, braquicefálico e dolicocéfalo). Os maiores diâmetros do ducto nasolacrimal e espessura do osso maxilar adjacente foram medidos quando a sutura lacrimomaxilar estava completamente visível. Além disso, as medidas foram realizadas 2 mm acima e abaixo do ponto médio. As medidas do osso maxilar e do ducto nasolacrimal foram analisadas por ANOVA de uma via com teste post hoc de Tukey. Resultados: Indivíduos do sexo feminino apresentaram ducto lacrimal significativamente mais estreito no ponto médio (p=0,026) e 2 mm acima (p=0,025). A espessura óssea maxilar foi maior nos indivíduos Classe II em comparação aos indivíduos Classe I no ponto médio (p=0,012) e 2 mm acima (p=0,027). O grupo dolicocefálico apresentou maior espessura óssea maxilar no ponto médio (p=0,014) e 2 mm abaixo (p=0,005) quando comparado ao grupo braquicefálico. A espessura óssea maxilar foi maior em indivíduos mesocefálicos em comparação com indivíduos dolicocéfalos (p=0,04). Conclusões: Indivíduos braquicefálicos Classe I apresentam menor espessura óssea maxilar adjacente ao ducto nasolacrimal, facto que aumenta o risco de lesão durante o processo de fixação óssea.

Abstract Objectives: To evaluate the anatomy of the nasolacrimal duct and the adjacent maxillary bone thickness using multislice computed tomography. Methods: Tomographic images of 92 individuals (184 sides) were analyzed according to sex, side, and sagittal (Class I, II, and III) and vertical (mesocephalic, brachycephalic, and dolichocephalic) skeletal patterns. The largest diameters of the nasolacrimal duct and the thickness of the adjacent maxillary bone were measured when the lacrimomaxillary suture was completely visible. In addition, the measurements were performed 2 mm above and below the midpoint. The maxillary bone and nasolacrimal duct measurements were analyzed by one-way ANOVA with Tukey’s post-hoc test. Results: Females had a significantly narrower lacrimal duct at the midpoint (p=0.026) and 2 mm above it (p=0.025). Maxillary bone thickness was greater in Class II individuals compared to Class I at the midpoint (p=0.012) and 2 mm above it (p=0.027). The dolichocephalic group had greater maxillary bone thickness at the midpoint (p=0.014) and 2 mm below it (p=0.005) compared to the brachycephalic group. Maxillary bone thickness was greater in mesocephalic individuals compared to dolichocephalic individuals (p=0.04). Conclusions: Brachycephalic Class I individuals have lower maxillary bone thickness adjacente to the nasolacrimal duct, which increases the risk of injury during the bone fixation process.

Research to identify plant bioactive compounds led to the evolution of extraction methods. This study optimized ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) to extract the flavonoids of Croton grewioides Baill. species contributing to characterize the polar extract profile and understand the antioxidant potential of these plant constituents. The use of experimental design and statistical treatments enabled the determination of the ideal conditions for each technique. The extracts of five accessions of C. grewioides were obtained under the optimized extraction conditions and were analyzed using ultra high-resolution mass spectrometry (FT-Orbitrap MS) operating at negative ionization mode for flavonoids detection. The accurate experimental mass obtained to the main compounds was used to attribute the molecular formula. Chemical structures of the main compounds detected were proposed using structure data bases. Chemometric analysis were performed with two FT-Orbitrap MS spectra samples using the identified metabolites and, the antioxidant activity data, showing that for this species the MAE was most effective in extracting the antioxidant compounds. It was possible to propose the structures for forty compounds in the C. grewioides extracts, demonstrating the excellent performance of the FT-Orbitrap MS in providing information on the chemical profile of polar compounds in plant extracts. methods ultrasoundassisted ultrasound assisted UAE (UAE microwaveassisted microwave (MAE Baill constituents technique C highresolution high resolution FTOrbitrap FT Orbitrap detection formula bases

BACKGROUND Dengue is a disease caused by dengue virus (DENV-1 through -4). Among the four serotypes, DENV-4 remains the least studied. Acute kidney injury is a potential complication of dengue generally associated with severe dengue infection. OBJECTIVES The goal of this study was to investigate the alterations caused by experimental dengue infection in the kidney of adult BALB/c mice. METHODS In this study, BALB/c mice were infected through the intravenous route with a DENV-4 strain, isolated from a human patient. The kidneys of the mice were procured and subject to histopathological and ultrastructural analysis. FINDINGS The presence of the viral antigen was confirmed through immunohistochemistry. Analysis of tissue sections revealed the presence of inflammatory cell infiltrate throughout the parenchyma. Glomerular enlargement was a common find. Necrosis of tubular cells and haemorrhage were also observed. Analysis of the kidney on a transmission electron microscope allowed a closer look into the necrotic tubular cells, which presented nuclei with condensed chromatin, and loss of cytoplasm. MAIN CONCLUSIONS Even though the kidney is probably not a primary target of dengue infection in mice, the inoculation of the virus in the blood appears to damage the renal tissue through local inflammation.

SUMMARY OBJECTIVE: The objective of this study was to evaluate possible cytogenetic changes in children and adolescents with human immunodeficiency virus on antiretroviral therapy, through the micronucleus test in oral mucosa. METHODS: This was a prospective study consisted of 40 individuals, of whom 21 comprised the human immunodeficiency virus group and 19 comprised the control group. Children and adolescents with human immunodeficiency virus were enrolled. The inclusion criteria were <18 years old and consent in participating in the study. The exclusion criteria were the presence of numerous systemic comorbidities, oral lesions, the habit of smoking, alcohol consumption, and X-rays or CT scans taken within 15 days prior to sample collection. A gentle scraping was performed on the inner portion of the jugal mucosa on both sides. A total of 2,000 cells per slide were analyzed for the determination of mutagenicity parameters as follows: micronuclei, binucleation, and nuclear buds. For measuring cytotoxicity, the following metanuclear changes were evaluated: pyknosis, karyolysis, and karyorrhexis, in a double-blind manner. The repair index was also evaluated in this setting. RESULTS: The human immunodeficiency virus group showed high frequencies of micronuclei (p=0.05), binucleated cells (p=0.001), and nuclear buds (p=0.03). In the cytotoxicity parameters, represented by the cell death phases, there was an increase with statistical difference (p≤0.05) in the karyorrhexis frequency (p=0.05). Additionally, repair index was decreased in the human immunodeficiency virus group. CONCLUSION: These results indicate that human immunodeficiency virus -infected individuals undergoing antiretroviral therapy have cytogenetic changes in oral mucosal cells.

Abstract Intimate partner violence (IPV) consists of acts that threaten to harm or actually harm to a partner within an affective-sexual relationship, regardless of the configuration or duration of the relationship or whether or not there is cohabitation between the parties. In homosexual relationships, IPV is made invisible in several ways, even though it is recognized as a serious violation of human rights. The study aimed to understand the meanings of IPV for a group of men in same sex relationships (MSSR). Eight MSSR participated in the research, selected by snowball sampling, used due to the topic’s sensitivity, considering the stigmas involved in being MSSR. Data were constructed via semi-structured interviews and analyzed using Thematic Analysis. As a result, six categories were constructed: 1) The closet persons; 2) Homophobia; 3) Racism, power, and vulnerability to IPV; 4) Sexuality; 5) Infidelity; 6) HIV, which discuss the intersectionality of various forms of oppression in the production of IPV among MSSR. Thus, the IPV experienced by this group is influenced by several factors that involve the intersectionality between different social markers, such as stereotypes of masculinity in relation to hypersexualization and infidelity, homophobia as a direct factor of minority stress, the racism that hierarchizes bodies and makes the affection of Black men and the stigma of HIV invisible in the social imaginary.

Resumen La violencia de pareja (VP) consiste en actos que amenazan con causar o de hecho causan daño a una pareja dentro de una relación afectivo-sexual, independientemente de la configuración o duración de la relación o de si existe o no cohabitación entre las partes. En las relaciones homosexuales, la VP se invisibiliza de varias formas, a pesar de que se reconoce como una grave violación de los derechos humanos. Este estudio tuvo como objetivo comprender los significados de VP para un grupo de hombres que se relacionan con hombres (HRH). Ocho HRH participaron de la investigación, seleccionados mediante la técnica de “bola de nieve”, utilizada debido a la sensibilidad del tema, considerando los estigmas de ser HRH. Los datos se construyeron mediante entrevistas semiestructuradas y se sometieron a análisis temático. Como resultado se construyeron seis categorías: 1.ª) El armario; 2.º) Homofobia; 3.º) Racismo, poder y vulnerabilidad a la VP; 4.º) Sexualidad; 5.º) Infidelidad; 6.ª) HIV; que discuten la interseccionalidad de diferentes formas de opresión en la producción de VP entre HRH. Se concluye que la VP vivida por este grupo está influida por varios factores que involucran la interseccionalidad entre distintos marcadores sociales, como los estereotipos de masculinidad en relación con la hipersexualización y la infidelidad, la homofobia como factor directo de estrés minoritario, el racismo que jerarquiza cuerpos e invisibiliza en el imaginario social el afecto de los hombres negros y el estigma del HIV en el imaginario social.

Resumo A violência por parceiro íntimo (VPI) consiste em atos que ameacem causar ou efetivamente causem danos em um parceiro dentro de uma relação afetivo-sexual, independente da configuração ou tempo do relacionamento ou de haver coabitação ou não entre as partes. Nas relações homossexuais, a VPI é invisibilizada de diversas maneiras, mesmo sendo reconhecida como uma grave violação de direitos humanos. O estudo objetivou compreender os significados da VPI para um grupo de homens que se relacionam com homens (HRH). Participaram da pesquisa oito HRH, selecionados através da técnica “bola de neve”, utilizada devido à sensibilidade do tema, considerando os estigmas de ser HRH. Os dados foram obtidos através de entrevista semiestruturada e foram analisados pela Análise Temática. Como resultados, foram construídas seis categorias: 1º) O armário; 2º) Homofobia 3º) Racismo, poder e vulnerabilidade a VPI; 4º) Sexualidade; 5º) Infidelidade; 6º) HIV, que discutem a interseccionalidade de diversas formas de opressão na produção de VPI entre HRH. Conclui-se que a VPI vivenciada por esse grupo é influenciada por diversos fatores que envolvem a interseccionalidade de vários marcadores sociais, como os estereótipos de masculinidade em relação a hipersexualização e infidelidade, a homofobia como fator direto do estresse minoritário, o racismo que hierarquiza os corpos e invisibiliza o afeto de homens negros, e o estigma de HIV no imaginário social.

SUMMARY OBJECTIVE: The objective of this study was to evaluate cytogenetic changes in individuals submitted to oral human immunodeficiency virus pre-exposure prophylaxis use through the micronucleus test in oral mucosa. METHODS: This study consisted of 37 individuals, of whom 17 comprised the pre-exposure prophylaxis group and 20 comprised the control group. A total of 2,000 cells per slide were analyzed for the determination of micronuclei, binucleation, nuclear buds, and cytotoxicity parameters: pyknosis, karyolysis, and karyorrhexis (KR), in a double-blind manner. The repair index was also evaluated in this setting. RESULTS: In the mutagenicity parameters, the pre-exposure prophylaxis group showed increased frequencies of micronuclei (p=0.0001), binucleation (p=0.001), and nuclear buds (p=0.07). Regarding the cytotoxicity parameters, there was an increase with a statistical difference (p≤0.05) in the karyorrhexis frequency (p=0.001). Additionally, the repair system efficiency decreased in the pre-exposure prophylaxis group. CONCLUSION: These results indicate that individuals undergoing pre-exposure prophylaxis use have geno- and cytotoxicity in oral mucosal cells.

Abstract The aim of this systematic review was to evaluate published papers regarding the micronucleus assay in oral mucosal cells of patients undergoing orthodontic therapy (OT). A search of the scientific literature was made in the PubMed, Scopus, and Web of Science databases for all data published until November, 2021 using the combination of the following keywords: “fixed orthodontic therapy,” “genetic damage”, “DNA damage,” “genotoxicity”, “mutagenicity”, “buccal cells”, “oral mucosa cells,” and “micronucleus assay”. The systematic review was designed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Nine studies were retrieved. Some authors demonstrated that OT induces cytogenetic damage in oral mucosal cells. Out of the nine studies included, two were classified as strong, five as moderate, and two as weak, according to the quality assessment components of the Effective Public Health Practice Project (EPHPP). Meta-analysis data revealed no relationship between mutagenicity in oral cells and OT in different months of treatment. At one month, the SMD = 0.65 and p = 0.08; after three months of OT, the SMD = 1.21 and p = 0.07; and after six months of OT, the SMD = 0.56 and p = 0.11. In the analyzed months of OT, I2 values were >75%, indicating high heterogeneity. In summary, this review was not able to demonstrate that OT induces genetic damage in oral cells. The study is important for the protection of patients undergoing fixed OT, given that mutagenesis participates in the multi-step process of carcinogenesis.

Abstract: Abusive relationships are those permeated by violence in an institutionalized way. We aimed to understand the meanings attributed by a group of young academics from Manaus to an abusive relationship. It is qualitative research. We carried out a focus group with eight participants and eight individuals using a semi-structured interview. Data were analyzed through the analysis of meaning cores. As a result, we built four nuclei of meanings: 1st) Jealousy; 2nd) Controlling Behavior; 3rd) Violence; 4) Experiences of the Victim, which showed that gender norms sustain a violent relationship, which is mediated by jealousy, control behaviors, and attempts at social isolation.

ABSTRACT Objective To describe cerebrovascular manifestations in patients hospitalized for treatment of severe COVID-19, highlighting the comorbidities observed, and those that may play a relevant role as risk factors for severe outcomes. Methods This case series retrospective analyzed, from June to November, 2020, ten patients admitted to the emergency department, with positive nasopharyngeal swab polymerase chain reaction assay for SARS-CoV-2, presenting with neurological symptoms and positive findings at brain imaging studies. Results In this sample, the clinical severity of the symptoms varied from mild to critical. Ischemic stroke was observed in four patients, hemorrhagic events occurred in five cases. Three patients evolved with large parenchymal hemorrhage, and one presented petechial bleeding foci. In one case, we observed subarachnoid hemorrhage associated with bilateral hypodensity in both globus pallidus. Typical posterior reversible encephalopathy syndrome findings were observed in one patient on brain computed tomography. Conclusion Patients with neurovascular complications related to COVID-19 had positive findings in brain imaging and neurological symptoms. The pathological entities observed drew attention to the neurological risk of patients with SARS-CoV-2 infection, including worse outcomes in individuals whose medical history includes clinical comorbidities, especially hypertension and obesity.

Abstract Objective: To evaluate the importance of computed tomography and computed tomography angiography (CTA) in stroke protocols, as well as their impact on endovascular treatment and on the determination of the etiology. Materials and Methods Were evaluated 28 patients with acute/hyperacute stroke in the anterior circulation who underwent intracranial and cervical CTA between April 2018 and August 2019. The parameters evaluated were the degree of stenosis, plaque characteristics, type of infarct, treatment, etiology, and the Alberta Stroke Program Early CT Score (ASPECTS). Results: Of the 28 patients evaluated, 16 (57.1%) had an ASPECTS of 10 (the maximum score, indicative of normality). Four patients (14.3%) underwent thrombolytic treatment, and seven (25.0%) underwent mechanical thrombectomy. The etiology was atherosclerosis in 32.1% of the patients, cerebral small-vessel disease in 7.1%, cardioembolic in 7.1%, and undetermined in 53.6%. Regarding plaque, 17.9% of the patients presented stenosis ≥ 50%, 21.4% presented stable plaques, and 42.9% presented vulnerable plaques. Patients with a lower ASPECTS were more likely to have relevant stenosis and were more likely to have a total infarct. Conclusion: In the evaluation of patients with acute/hyperacute strokes, CTA provides important information, identifying occlusion, as well as helping define the etiology and inform decisions regarding treatment.

Resumo Objetivo: Avaliar a importância da tomografia computadorizada e angiotomografia computadorizada (ATC) no protocolo de acidente vascular encefálico (AVE) e o seu impacto no tratamento endovascular e na determinação da etiologia. Materiais e Métodos: Foram avaliados 28 pacientes com AVE agudo/hiperagudo da circulação anterior que realizaram ATC intracraniana e cervical, no período de abril de 2018 a agosto de 2019. Os parâmetros avaliados foram grau de estenose, placa, tipo do infarto, tratamento, etiologia e classificação Alberta Stroke Program Early CT Score (ASPECTS). Resultados: A maioria dos casos (16; 57,1%) apresentou ASPECTS de 10. Quatro pacientes (14,3%) realizaram tratamento trombolítico e sete (25%) foram submetidos a trombectomia mecânica. A etiologia foi aterosclerose em 32,1% dos pacientes, doença de pequenas artérias em 7,1%, cardioembólico em 7,1% e indeterminada em 53,6%. Em relação à placa, 17,9% apresentaram estenose maior que 50%, 21,4% apresentaram placas estáveis e 42,9%, placas instáveis. Pacientes com ASPECTS mais baixo apresentavam maior probabilidade de ter estenose relevante e apresentavam maior chance de ocorrência de infarto total. Conclusão: A ATC fornece informações importantes na avaliação do paciente com AVE agudo/hiperagudo, identificando a oclusão e auxiliando na definição da etiologia e no direcionamento do tratamento.

ABSTRACT Objective: This study investigated the acute effects of high-intensity interval (HIIE) and moderate-intensity continuous (MICE) exercise on ghrelin levels in obese men. Subjects and methods: A total of 10 obese men (age 27.6 ± 1.8 years, body mass index 35.4 ± 4.5 kg/m², body fat 39.9 ± 2.1%) performed two exercise sessions in a randomized order: HIIE (10 × 1 min intervals at 90% of the maximal heart rate [HRmax] interspersed by 1 min of active recovery) and MICE (20 min at 70% of the HRmax). Ghrelin levels were assessed pre-, post- and 1h post-exercise, and energy intake was assessed 1h post-exercise through an ad libitum meal. Results: HIIE and MICE showed a trend to decrease ghrelin levels immediately post-exercise (-14.1 ± 21.6% and −9.6 ± 23.8%, respectively, p = 0.07) and decreased 1h post-exercise (-12.7 ± 31.8% and −13.8 ± 21.7%, respectively, p < 0.05). No changes were observed for post-exercise energy intake (p > 0.05). There was a positive correlation between the change in ghrelin levels and post-exercise energy intake only for HIIE (r = 0.63, p = 0.05). Conclusion: In summary, a single session of HIIE and MICE elicits a reduction on ghrelin levels without changing post-exercise energy intake in obese men.

Abstract Background: In Central and South America, snakebite envenomation is mainly caused by Bothrops spp. snakes, whose venoms feature significant biochemical richness, including serine proteases. The available bothropic antivenoms are efficient in avoiding fatalities, but do not completely neutralize venom serine proteases, which are co-responsible for some disorders observed during envenomation. Methods: In order to search for tools to improve the antivenom’s, 6-mer peptides were designed based on a specific substrate for Bothrops jararaca venom serine proteases, and then synthesized, with the intention to selectively inhibit these enzymes. Results: Using batroxobin as a snake venom serine protease model, two structurally similar inhibitor peptides were identified. When tested on B. jararaca venom, one of the new inhibitors displayed a good potential to inhibit the activity of the venom serine proteases. These inhibitors do not affect human serine proteases as human factor Xa and thrombin, due to their selectivity. Conclusion: Our study identified two small peptides able to inhibit bothropic serine proteases, but not human ones, can be used as tools to enhance knowledge of the venom composition and function. Moreover, one promising peptide (pepC) was identified that can be explored in the search for improving Bothrops spp. envenomation treatment.

RESUMO Este trabalho investigou a influência da volatilidade cambial sobre as exportações brasileiras para os Estados Unidos entre janeiro de 1999 a fevereiro de 2017. Para tanto, empregou-se o teste de fronteira de Pesaran em uma estrutura ARDL. Adicionalmente foram construídas medidas não lineares para a volatilidade cambial a fim de verificar se choques positivos e negativos no câmbio afetam igualmente sua volatilidade. As medidas não lineares propostas indicaram que choques positivos no câmbio implicam em maior volatilidade para os períodos seguintes. Os resultados dos testes de Pesaran mostraram que a influência a longo prazo da volatilidade cambial nas exportações é similar para as diferentes medidas, contudo, os modelos considerando medidas não lineares obtiveram mais relações positivas do que os com medidas lineares. Os setores negativamente afetados foram produtos com dependência do capital externo e produtos manufaturados ou com baixo valor agregado. Os setores positivamente afetados foram produtos sem dependência do capital externo ou com demanda altamente elástica.

ABSTRACT This paper investigated the influence of exchange-rate volatility on Brazilian exports to the US from January 1999 to February 2017. For this purpose, we used Pesaran’s bound test in an ARDL framework. Moreover, we built nonlinear measures for exchange-rate volatility to verify whether positive and negative exchange rate shocks affect equally on volatility. The proposed nonlinear measures indicated that positive exchange rate shocks imply greater volatility in the following periods. The results showed that long-term exchange rate volatility affected the exports similarly for the different measures. However, we found more positive relationships in the models using nonlinear measures than in those using linear ones. The sectors negatively affected were external capital-dependent products and manufactured or low value-added products. In contrast, the ones positively affected were products with no dependence on external capital or products with highly elastic demand.
