Published: March 2019

Objective: The present study assessed the fracture strength of teeth subjected to endodontic access cavity preparation on buccal surfaces, or with the aid of operating microscopy when compared to the conventional technique. Material and methods: Sixty mandibular incisors were split into four groups (n=15): conventional access cavity preparation (CCP); conservative (C); buccal surface (BS); and control. The canals were prepared and filled and the cavities were restored. A static compressive strength test was conducted until crown fracture. The force data were compiled and assessed statistically. Kolmogorov-Smirnov and Shapiro-Wilk tests were performed to assess normality, Levene’s test to assess variance homogeneity, the one-way ANOVA to compare fracture strength in the assessed groups. Tukey’s HSD test was used to determine whether the differences in the means were significant between the groups.Results: The experimental groups did not show any statistically significant differences in mean fracture strength (CCP = 585.65 N±107.64 N)(BS = 530.52 N±129.35 N) (C = 517.83 N±114.68 N). Conclusion: Therefore, the selection of surface or size of access cavity proposed did not influence the fracture strength of mandibular incisors when compared to conventional cavity preparation.

Objective: To describe and compare potential differences in systemic health characteristics and xerostomia among residents in American and Brazilian nursing facilities (NF). Material and Methods: This secondary analysis used data from a study in NF located in Iowa-USA (n=81) and Sao Paulo (SP)-Brazil (n=119). Recorded data included demographics, medications, comorbid conditions, and self-reported xerostomia. Results The Iowa group mean age was 82.1 years (±12.9), 60.5% were females, and 100% were white, whereas the SP group mean age was 76.4 years (±8.7), 47.9% females, most participants identified as either white (42.0%) or as more than one race (45.4%). The median number of comorbid conditions and medications in the Iowa were 9 and 12, respectively, as compared to 2 and 6 in SP. Most common comorbidities in Iowa were hypertension, dementia (including Alzheimer), and depression. In SP, they were hypertension, unspecified diabetes mellitus (including type 2), and Parkinson. Most common prescription medications in Iowa were acetaminophen, acetylsalicylic acid, and magnesium hydroxide, while in SP, they were omeprazole, acetylsalicylic acid, and losartan. Xerostomia was reported by 32.1% (Iowa) and 59.7% (SP) of the participants. There was no association between age and dry mouth sensation in either Iowa (p=0.480) or SP (p=0.130) samples. However, there was an association between total medications and dry mouth sensation in Iowa (p=0.040), but not in SP (p=0.075) Conclusions: Iowans presented with higher numbers of comorbidities and prescription medications, however xerostomia was reported in a greater percentage in SP. Xerostomia was associated to higher number of medications in Iowa, but not in SP. KeywordsXerostomia; Aged; frail elderly; Nursing homes.

Published: March 2019

Objective: To evaluate the fracture resistance (RF) of Class II Glass-ionomer Cement (GIC) ART restorations with and without proximal retentions. Material and Methods: 20 freshly extracted human molars were used. Forty (40) standard Mesial-Occlusal (MO) and Distal-Occlusal (DO) preparations (20 for each material) were performed with a 245 bur. The unprepared surfaces of the teeth were protected with nail polish and the specimens submerged in 0.5Mol EDTA solution, pH 7.4 for 8h under stirring. The preparations were finished with dentine spoons and 50% received proximal retention with # 3 excavators. 20 cavities were restored with Chemfil Rock (10 with retention and 10 without retention) and 20 cavities were restored with Equia Fil (10 with retention and 10 with no retention) and were stored in an oven at 37ºC and 100% relative humidity for 24h and submitted to axial compression loading in Test Machine - EMIC at a rate of 0.5 mm / minute, until restoration fracture occurred. The values were analyzed by two-way ANOVA (p<0.05). Results: ChemFil Rock presented 300.84 (69.20) (without retention) and 361.70 (81.08) (with retention) and Equia Fil showed 314.60 (69.97) (without retention) and 366.67 (103.38) (with retention). Data obtained with retention were statistically superior to those obtained with non-retained ART restorations (p=0.014). No statistical differences were detected between materials (p=0.761). Conclusion: Retentive grooves improved fracture resistance of Class II GIC ART restorations. KeywordsDental materials; ART; Glass ionomer cements.
O espaço do teatro, a cidade e a política: diálogos possíveis
Authors: Lima Evelyn Furquim Werneck 
Published: March 2019

Para atestar a possibilidade de diálogo entre o teatro, a cidade e a política, este artigo analisa três eventos de natureza distinta, em diferentes momentos da história brasileira: a adaptação, durante a ditadura militar, de Na selva das cidades (1969), de Brecht, por Zé Celso, à frente do Grupo Oficina, focando a cidade de São Paulo; os espetáculos O tiro que mudou a história e Tiradentes (1992), dirigidos por Aderbal Freire-Filho, que valorizam o teatro em espaços históricos e tombados da cidade do Rio de Janeiro; e a peça BR3, verdadeiro manifesto sociopolítico, encenada em São Paulo pelo Teatro da Vertigem (2006) e dirigida por Antônio Araújo. Nesta análise, a cidade se apresenta ora como representação, ora como suporte da cena ou como a própria dramaturgia, tendo como base conceitos formulados por Patrice Pavis, Christine Boyer e Marc Augé.

Jogando com imagens: as disputas sobre os sentidos da capoeira na revista ilustrada O Cruzeiro
Authors: Pinheiro Bruno 
Published: March 2019

As fotorreportagens “Delinquência juvenil” (1 fev. 1947), assinadas pelo fotojornalista Jean Manzon e pelo jornalista David Nasser, e “Capoeira mata um!” (10 jan. 1948), do então fotojornalista Pierre Verger e do folclorista Cláudio “Tuiuti” Tavares, são analisadas como parte da continuidade dos debates em torno da descriminalização da capoeira, ocorrida em 1937. Na primeira, evidenciam-se os modos de representar o tema que eram populares no período anterior a 1937, em que ocupava quase que unicamente as páginas policiais. Na segunda, estão presentes as formas difundidas nos anos seguintes, quando a capoeira migrou para as páginas de cultura. Após delinear as filiações visuais e intelectuais dos autores nessa disputa, seus conteúdos serão aproximados às representações da capoeira que permeiam o romance Capitães da areia (1937), de Jorge Amado, tomado como referência comum a ambas as publicações, buscando explicitar os limites das narrativas jornalísticas sobre a temática.

“Eu quero frátria”: a comunidade do rap
Authors: Naves Santuza Cambraia 
Published: March 2019

O texto trata das rupturas empreendidas pelo rap com a categoria Estado-nação, ao recorrer discursiva e musicalmente à ideia de comunidade. Promove-se um deslocamento do conceito de “nação”, substituindo o espaço geográfico que corresponde às suas fronteiras por um outro, cujo limite obedece a um corte transversal no planeta marcado pela trajetória do negro. Assim, os rappers, ancorados na bandeira da negritude, reconstroem a própria genealogia. Quando adotam esta atitude, os rappers brasileiros tomam como ancestrais tanto os sambistas do partido-alto e repentistas quanto músicos norte-americanos, em busca de um legado musical e comportamental. Esse tipo de “atitude” será comparada com os pressupostos nacional-populares que nortearam a MPB na década de 1960, cujos músicos pensavam o “Brasil” e o “povo” numa perspectiva totalizante.

A janela de Carolina e o espelho de Lindoneia: duas antimusas de um mundo que se desagrega
Authors: Napolitano Marcos 
Published: March 2019

Este artigo visa analisar, a partir de uma perspectiva histórica, duas canções dos anos 60: “Carolina” (Chico Buarque, 1967) e “Lindoneia” (Caetano Veloso e Gilberto Gil, 1968). Sob uma ótica intertextual e contrapontística, sugerimos que a análise das duas composições, principalmente das suas letras (mas também de alguns aspectos musicais), revela uma configuração histórica tensa, retrato dos dilemas da modernização brasileira, potencializados pelo golpe militar de 1964.

Published: March 2019

AbstractLymphadenectomy is critical in the clinical prognosis of ovarian cancer patients. Therefore, we assessed whether lymph node ratio (LNR) has predictive value on overall survival (OS) of patients with serous epithelial ovarian cancer (SEOC). A total of 7,815 eligible SEOC patients were identified from the Surveillance, Epidemiology, and End Results (SEER) database, who underwent surgical resection between 1973 and 2013. We used the time-dependent receiver operating characteristic (ROC) curve and the area under curve to determine the optimal cut-off value of LNR. The predictive role of LNR was analyzed by Cox proportional hazards regression model. The effects of LNR and positive lymph nodes (PLN) on OS were evaluated by comparing the time-dependent ROC curves. The time-dependent ROC curves showed that the optimal LNR cut-off value was 42.0% for nodal-positive SEOC. As shown in Kaplan-Meier survival curves, survival was significantly poorer for all patients with LNR≥42.0% (log-rank test: P<0.0001), regardless of the stage. In the multivariate Cox analysis, LNR≥42.0% remained a significant and independent predictor of mortality risk for all patients [hazards ratio: 1.526, 95% confidence interval: 1.415-1.647; P<0.0001], compared with those LNR<42.0%. These results suggest that LNR, rather than the number of PLN or stage, could be regarded as a promising predictor of mortality risk, particularly in stage-III SEOC patients.
When grammar clashes: Negotiation of guilt and innocence in courtroom discourse
Authors: Chaemsaithong Krisda 
Published: March 2019

AbstractAdopting a functional view of language, this study critically explores clausal patterns in lawyers’ opening address in an American criminal trial. Underpinned by the assumption that no linguistic options are value-free, the quantitative and qualitative analysis uncovers the syntactic choices employed by the opposing sides and accounts for them in terms of the presenters’ ideological positions concerning the guilt and innocence of the defendant. The findings reveal stark differences between the two sides. Such systematic differences in clausal configurations not only constitute a prime meaning-making strategy that serves to construct polarized positioning of the same people and events, but are also likely to strike a profound impact with the jurors, potentially leading them to make tentative conclusions at this initial stage of case presentation.

Published: March 2019

OBJECTIVES:Maternal smoking during pregnancy is an established risk factor for sudden unexpected infant death (SUID). Here, we aim to investigate the effects of maternal prepregnancy smoking, reduction during pregnancy, and smoking during pregnancy on SUID rates.METHODS:We analyzed the Centers for Disease Control and Prevention Birth Cohort Linked Birth/Infant Death Data Set (2007–2011: 20 685 463 births and 19 127 SUIDs). SUID was defined as deaths at &lt;1 year of age with International Classification of Diseases, 10th Revision codes R95 (sudden infant death syndrome), R99 (ill-defined or unknown cause), or W75 (accidental suffocation or strangulation in bed).RESULTS:SUID risk more than doubled (adjusted odds ratio [aOR] = 2.44; 95% confidence interval [CI] 2.31–2.57) with any maternal smoking during pregnancy and increased twofold between no smoking and smoking 1 cigarette daily throughout pregnancy. For 1 to 20 cigarettes per day, the probability of SUID increased linearly, with each additional cigarette smoked per day increasing the odds by 0.07 from 1 to 20 cigarettes; beyond 20 cigarettes, the relationship plateaued. Mothers who quit or reduced their smoking decreased their odds compared with those who continued smoking (reduced: aOR = 0.88, 95% CI 0.79–0.98; quit: aOR = 0.77, 95% CI 0.67–0.87). If we assume causality, 22% of SUIDs in the United States can be directly attributed to maternal smoking during pregnancy.CONCLUSIONS:These data support the need for smoking cessation before pregnancy. If no women smoked in pregnancy, SUID rates in the United States could be reduced substantially.
China and Latin America, from neo-colonialism to interdependence? Brazil Case
Authors: Suarez Torres Angela Piedad 
Published: March 2019

Since the eighties, the relationship that China has developed with Latinomerica has been strengthened, becoming the third most important partner in the region. This regulation is not only the opening of a new market for China but varied opportunities for Latin-American countries. However, starting from the topic of natural resources and analyzing the case of Brazil, the article seeks to present how this relationship that in principle is framed in Neocolonialism, with interests merely of extraction and use of the resources of the region, can be considered a change towards a more equitable relationship framed in interdependence, from which the two parties can benefit.Desde los años ochenta, la relación que China ha desarrollado con Latinomerica se ha ido fortaleciendo, llegando a convertirse en el tercer socio mas importante de la region.
