O caminho da violência pelas narrativas jornalísticas: a patologização do machismo
Este trabalho apresenta uma análise sobre a patologização do machismo por meio das narrativas dos jornais O Popular e Diário da Manhã de 2016 e 2017. Procura-se categorizar a construção e os argumentos dessas narrativas no que tange à temática da violência de gênero e do processo de revitimização. Para tanto, buscou-se articular leituras de gênero, comunicação e direitos humanos com o fito de evidenciar a ocorrência de violência de gênero no processo de revitimização das mulheres violentadas, convertidas em objeto de representações jornalísticas. A forma como as mulheres em situação de violência foram abordadas nas matérias analisadas denotou que estas apresentam conteúdos e narrativas estruturadas a partir de regimes simbólicos correntes em outros campos da vida social que naturalizam relações violentas e desiguais. Assim, as dinâmicas jornalísticas também assumem o papel de agentes de violência – numa dimensão simbólica – nesse processo, em que se encontra a dinâmica da revitimização midiática.Este trabajo analizó la patologización del machismo en las narrativas de los periódicos O Popular y Diário da Manhã en el periodo del 2016 al 2017.

Por ello, se articulan lecturas de género, comunicación y derechos humanos con el fin de resaltar la ocurrencia de violencia de género en el proceso de revictimización de mujeres violadas, convertidas en objetos de representaciones periodísticas. Los artículos periodísticos sobre las mujeres en situaciones de violencia presentan contenidos y narrativas estructuradas a partir de regímenes simbólicos vigentes en otros campos de la vida social que naturalizan las relaciones violentas y desiguales. Así, las dinámicas periodísticas también asumen el papel de agentes de violencia –en una dimensión simbólica– en este proceso, en que se encuentra la dinámica de revictimización de los medios.This work shows a general analysis on the pathologization of machismo by narratives of newspapers O Popular and Diário da Manhã from 2016 to 2017. It seeks to categorize the construction and the arguments of these narratives regarding the theme of gender violence and the re-victimization process. To this end, we sought to articulate readings of gender, communication, and human rights aiming to show the occurrence of gender violence in the process of re-victimization of abused women, converted into the object of journalistic representations. The ways in which women in situations of violence were approached in the analyzed materials showed that they present content and narratives structured from symbolic regimes current in other fields of social life which naturalize violent and unequal relationships. Thus, the journalistic dynamics also assume the role of agents of violence – in a symbolic dimension – in this process, where the dynamics of media re-victimization is found
Culpar a vítima ainda é o modus operandi da linguagem jornalística? Análise dos títulos no webjornalismo do portal G1 sobre o estupro (quadriênio 2016-2019)
Este artigo adotaa análise de discurso crítica(ADC) como caminho para analisar os títulos de webjornalismo no período de 2016 a 2019, veiculadas no G1, uma das maiores plataformas de jornalismo digital no Brasil, para verificar como os discursos midiáticos persistem nas práticas narrativas que culpabilizam as mulheres vítimas de estupro. A despeito dos progressos alcançados no ordenamento jurídico e nas políticas públicas de combate à violência, no campo da linguagem as mulheres vítimas de estupro, continuam sendo culpabilizadas. Os dados coletados indicam que os títulos das notícias digitais, no período de 2016 a 2019, utilizam expressões linguísticas que atribuem à mulher a culpa pela violência sofrida, o que contribui para a reprodução e manutenção da violência de gênero
Examination of temporomandibular disorders in the orthodontic patient: a clinical guide
The possible association between orthodontic treatment and temporomandibular disorders (TMD) is a topic of great interest in the current literature. The true role of orthodontic therapy on the etiology of TMD, however, is still uncertain. From the clinical prospective, a thorough examination of the stomatognathic system is always necessary in order to detect possible TMD signs and symptoms prior to the beginning of the orthodontic therapy. Caution should be exercised when planning, performing and finalizing orthodontics, especially in patients who with history of signs and symptoms of TMD. The clinician must always eliminate patient's pain and dysfunction before initiating any type of orthodontic mechanics. Muscle incoordination, unstable disc-condyle relationship and bone alterations are usual TMD conditions that can interfere with the presenting occlusal relationship. This article reviews these aspects and presents a detailed clinical guide for the examination of the orthodontic patient, considering aspects related to facial pain and dysfunction
Estabilidade a longo prazo do tratamento da mordida aberta anterior na dentadura mista: relato de caso clínico
Apresentou-se um relato de caso clínico de mordida aberta anterior, tratada em dentadura mista, demonstrando uma das possíveis formas de tratamento, capaz de interferir no crescimento e redirecionar seus vetores. Os protocolos ortodônticos e ortopédicos utilizados foram a expansão lenta da maxila, utilizando grade palatina soldada a um expansor bihélice, com tração alta na mandíbula, num período diário de 16 horas. Oito anos de estabilidade foram alcançados, explicados pelo fato de o tratamento ter sido conduzido no momento oportuno do desenvolvimento, o que estabeleceu equilíbrio entre os músculos peribucais, em conjunto com o período final do crescimento. A combinação do tratamento ortodôntico e ortopédico foi necessária para se evitar a necessidade de tratamento cirúrgico.A clinical case with anterior open-bite, treated in the mixed dentition, is presented. This approach demonstrates one of the possible approaches of treatment, which is capable of interfering with growth and redirecting its vectors. Orthodontic and orthopedic methods were used, consisting of slow maxillary expansion, through a fixed palatal crib soldered in a bi-helix appliance, and high-pull traction on the mandible for 16 hours a day. After eight years of follow-up, stable outcomes were accomplished. These results may be explained by the fact that treatments were performed at the appropriate period of development, thus establishing perioral muscular equilibrium, matching the final period of facial growth. The combination of orthodontic and orthopedic treatments was necessary to prevent the need of further orthognathic surgery treatment
Positive Effects of Extra-Virgin Olive Oil Supplementation and DietBra on Inflammation and Glycemic Profiles in Adults With Type 2 Diabetes and Class II/III Obesity: A Randomized Clinical Trial
Background: Evidence on the effects of dietary interventions on inflammatory markers in individuals with obesity and type 2 diabetes mellitus (T2DM) is scarce. Our study evaluated the effects of extra-virgin olive oil alone and in combination with a traditional Brazilian diet on inflammatory markers and glycemic profiles in adults with both T2DM and class II/III obesity. Methods: Adults aged 18-64 years with T2DM and class II/III obesity were randomized into two intervention groups: 1) extra-virgin olive oil only and 2) extra-virgin olive oil + a traditional Brazilian diet (OliveOil+DietBra). Data on sociodemographic characteristics, lifestyle, anthropometry, biochemical markers and inflammatory markers were collected. The primary outcomes were glycemic parameters and inflammatory markers. The body mass index (BMI) and weight were the secondary outcomes. Results: Forty individuals with T2DM and class II/III obesity were enrolled, and 34 (85%) completed the intervention course. The intake of olive oil was 37.88 ± 12.50 mL/day in the olive oil group and 37.71 ± 12.23 mL/day in the OliveOil+DietBra group, with no significant difference between groups (p = 0.484). Compared to the olive oil only group, the OliveOil+DietBra group had significantly lower levels of fasting insulin (p = 0.047) at the end of the intervention, whereas the other glycemic parameters were not altered. In the OliveOil+DietBra group, serum levels of inflammatory cytokines, IL-1α (p = 0.006) and adiponectin (p = 0.049) were lower and those of TNFα were higher (p = 0.037). There was a significant reduction in BMI and weight compared to the baseline values in the OliveOil+DietBra group (p = 0.015). Conclusions: The intervention with OliveOil+DietBra effectively decreased the levels of fasting insulin, IL-1α and adiponectin, suggesting its beneficial role in improving the inflammatory profiles and fasting insulin levels in adults with class II/III obesity and T2DM.

Comparison of manual, digital and lateral CBCT cephalometric analyses
Objective: The aim of this study was to compare the reliability of three different methods of cephalometric analysis. Material and Methods: Conventional pretreatment lateral cephalograms and cone beam computed tomography (CBCT) scans from 50 subjects from a radiological clinic were selected in order to test the three methods: manual tracings (MT), digitized lateral cephalograms (DLC), and lateral cephalograms from CBCT (LC-CBCT). The lateral cephalograms were manually analyzed through the Dolphin Imaging 11.0™ software. Twenty measurements were performed under the same conditions, and retraced after a 30-day period. Paired t tests and the Dahlberg formula were used to evaluate the intra-examiner errors. The Pearson's correlation coefficient and one-way analysis of variance (ANOVA) tests were used to compare the differences between the methods. Results: Intra-examiner reliability occurred for all methods for most of the measurements. Only six measurements were different between the methods and an agreement was observed in the analyses among the 3 methods. Conclusions: The results demonstrated that all evaluated methodologies are reliable and valid for scientific research, however, the method used in the lateral cephalograms from the CBCT proved the most reliable

Tomographic evaluation of dentoskeletal effects of rapid maxillary expansion using Haas and Hyrax palatal expanders in children : a randomized clinical trial
Rapid maxillary expansion (RME) is a usual procedure for correcting the transversal maxillary deficiency. Among the most used appliances are the Haas type (tooth-tissue-borne) and Hyrax (tooth-borne) whose main difference is the design. This study aimed to evaluate the dentoskeletal effects of RME using two different expanders in children. The sample was composed of 42 children of both gender presenting unilateral or bilateral posterior crossbite with mean age 9.49 (SD± 1.35). Patients were randomized into two groups according to the type of expander: Hyrax (n= 21, 9 boys and 12 girls) and Haas (n= 21, 11 boys and 10 girls). Multiplanar coronal and axial slices obtained from cone-beam computed tomography images (i-Cat, Hartsfield, PA, USA) were used at pretreatment (T1) and after 6 months when the expander was removed (T2). Measurements were performed on Dolphin Imaging Systems 11.7 software (Chatsworth, California, USA). The following variables were evaluated: inclinations of the posterior teeth, transverse skeletal widths, length of maxillary dental arch, buccal bone thickness and level of buccal alveolar crest. Statistical analysis performed using chi-squared test to compare the sex ratios between groups and independent t test with the Bonferroni correction for multiple tests. RME increased all maxillary transverse dimensions, regardless of the type of expanders used. Subjects in the Hyrax group experienced significantly increase in the lingual bone thickness (0.94 mm) compare to Haas group (0.21 mm). The Hyrax-type expander produced greater increase in the lingual bone thickness than did the Haas-type expander, but this effect might not be clinically significant. Both appliances presented similar transversal gain and tended to produce similar orthopedic and orthodontic effects
Dredging impact on trace metal behavior in a polluted estuary: a discussion about sampling design
Studies involving coastal sediment resuspension have shown that trace metals could be released to the water column due to changes in physical-chemical conditions. Therefore, if environmental agencies adopt screening protocols with insufficient evaluations of contaminant mobilization risks for a given area, the prediction of environmental impacts caused by dredging may be limited. This work evaluates the influence of spatial variation on the geochemical mobility of trace metals (Cd, Cu, Ni, Pb, Zn) after artificial sediment resuspension, using as study case the Iguaçu River estuary (Guanabara Bay, Brazil). The Iguaçu River drains the industrial complex of the metropolitan area of Rio de Janeiro State, besides the presence of agriculture and the input of untreated domestic wastes. Surface estuarine sediments were submitted to resuspension experiments in an open system, during 1h and 24h of agitation on local water. A clear tendency of metals’ solubilization was observed after resuspension, especially considering the dissolved concentrations of Cu (average: 8.0 µg L-1) and Zn (average: 0.9 mg L-1), especially for the samples from the transects 2 and 3. However, evaluations of water quality changes due to sediment resuspension are not requested by the legislation regulating the dredging activities. In the sediments, the results suggested a higher geochemical mobility of Cu, indicated by the massive increase on the bioavailable fraction after resuspension, mainly on the transect number 3, on the river’s mouth. The effects of resuspension were distinct between samples, suggesting that even in a small scale, important differences on metals’ mobility are found. Thus, the combined assessment of changes in metal concentrations in water and in the metal partitioning linked to the solid-phase was demonstrated to be a promising tool for predicting the environmental risks of dredging due to changes in the bioavailability of metals
