A saúde indígena nas cidades: redes de atenção, cuidado tradicional e intercultural / Indigenous health in cities: care networks, traditional and intercultural care

O livro "A saúde indígena nas cidades: redes de atenção, cuidado tradicional e intercultural", se consolidou a partir de trabalhos e incursões desenvolvidos junto aos povos indígenas no Brasil, com especial atenção aos que vivem em contextos urbanizados. O conjunto da obra aborda experiências na atenção básica e especializada com populações indígenas, o trabalho em saúde indígena, promoção e educação em saúde indígena, vigilância de agravos com populações indígenas, cuidado tradicional e intercultural, ações de enfrentamento da covid-19 nos territórios na relação com as redes de atenção instituídas nos centros urbanos de cidades situadas nos estados do Amazonas, Tocantins, São Paulo, Mato Grosso, Santa Catarina. O livro concentra um conjunto de relatos e resultados de pesquisas, bem como reflexões fundamentadas sobre processos, estruturas e contextos diferenciados de produção de cuidado, na perspectiva da multiculturalidade, representativos das populações indígenas que acessam os serviços de saúde de quatro das cinco regiões brasileiras. Assim, a obra colabora com a realização de um mundo melhor, quando apresenta dispositivos, arranjos e agenciamentos para a produção do cuidado junto a populações vulneráveis socioambientalmente, contrariando um sistema social discriminatório para indígenas que gera desigualdades sociais, principalmente nos centros urbanos.

Computational Prediction of Tc-99 NMR Chemical Shifts in Technetium Complexes with Radiopharmaceutical Applications.

The Tc-99m nucleus is the most used nuclide in radiopharmaceuticals designed for imaging diagnosis. The metal can exist in nine distinct oxidation states and forms distinct coordination complexes with a variety of chelating agents and geometries. These complexes are usually characterized through Tc-99 NMR that is very sensitive to the Tc coordination sphere. Therefore, predicting Tc-99 NMR might be useful to assist experimentalists in structural characterization. In the present study, we propose three computational protocols for predicting Tc-99 NMR chemical shifts based on density functional theory calculations using relativistic and nonrelativistic Hamiltonians: the relativistic Model 1, the nonrelativistic Model 2, and the empirical nonrelativistic Model 3. In Models 2 and 3, the NMR-DKH basis set was used for all atoms, including the Tc, for which it was developed here. All models were applied for a set of 41 Tc-complexes with metal oxidation states 0, I, and V, for which the Tc-99 chemical shift was available experimentally. The mean absolute deviation and the mean relative deviation were 67 ppm and 4.8% (Model 1), 92 ppm and 6.2% (Model 2), and 65 ppm and 4.9% (Model 3), respectively. Last, the effect of the explicit solvent was evaluated for the [TcO2(en)2]+─Tc(V) complex. The calculated results for the Tc-99 NMR chemical shift at SO-ZORA-SSB-D/TZ2P-ZORA/COSMO//TPSS/def2-SVP/IEF-PCM(UFF) show that the inclusion of 14 water molecules (first solvation shell) together with the implicit solvation model leads to an absolute deviation of only 7 ppm (0.3%) from the experimental value, indicating that the solvent effects play a key role in predicting Tc-99 NMR.

Evidence of genotoxicity and cytotoxicity of X-rays in the oral mucosa epithelium of adults subjected to cone beam CT.

OBJECTIVES: To assess cytological evidence of genotoxicity and cytotoxicity of X-rays in oral exfoliated cells of adults subjected to partial and total cone beam CT (CBCT) (stitching module) by means of micronuclei frequency, associated with counting of degenerative nuclear alterations (pyknosis, karyolysis, karyorrhexis, buds and broken eggs), besides comparing the partial and total CBCT (stitching module) in search of possible differences in the nature and/or intensity of the effects. METHODS: 29 adults who were referred to total or partial CBCT were selected. All CBCT were performed with a Carestream CS 9000 3D scanner (Carestream Health Inc., Rochester, NY). Material collection was done immediately before CBCT and 10 days later, by scraping the left and right cheek mucosa with a plastic spatula. Statistical analysis was performed using the Wilcoxon test (paired data), at a significance level of 5%. RESULTS: The statistically significant difference was noted in the frequency of micronucleated cells for both partial and total acquisition (p = 0.008 and p < 0.001, respectively). Regarding to cytotoxicity, there was a statistically significant difference for both partial and total acquisition (p < 0.001 and p < 0.001, respectively). CONCLUSIONS: The partial and total CBCT seems to offer risks of inducing genetic damage. In addition both forms of CBCT acquisition have promoted the induction of cytotoxic nuclear alterations.

Valores organizacionais e suporte social no trabalho: a percepção dos colaboradores do setor bancário público e privado / Organizational values and social support at work: the perceptions of employees of public and private sector banking

Este trabalho foi desenvolvido com o propósito de compreender a influência dos valores organizacionais sobre a percepção de suporte social no trabalho, sob a perspectiva dos colaboradores do setor bancário público e privado. Através de uma survey, foram investigados 332 colaboradores do setor bancário, aos quais foram aplicados um questionário elaborado a partir dos modelos IPVO e EPSST. Os principais resultados encontrados expõem que os valores organizacionais prioritários das instituições bancárias foram o Domínio e o Prestígio, enquanto os valores Bem-estar, Autonomia e Realização ocuparam lugares inferiores na hierarquia. Em relação ao suporte social no trabalho, a maior incidência foi atribuída ao Suporte Social Informacional, enquanto a menor prioridade foi atribuída ao Suporte Social Emocional. Ainda, as análises de regressão múltipla revelaram que o modelo com maior poder de explicação foi representado pela variável Geral Suporte, cuja variância foi explicada em 45,6 por cento pelos fatores Autonomia e Realização, Prestígio e Domínio.(AU)

This work was developed with the aim of understanding the influence of organizational values on the perception of social support at work, from the perspective of employees of public and private banking. Through a survey, we investigated 332 employees from the banking sector, who were asked to answer a questionnaire developed from the models IPVO and EPSST. The main findings state that the priority organizational values of the banking institutions were Dominion and Prestige, while the values such as Wellbeing, Empowerment and Accomplishment occupied lower levels in the hierarchy. As regards social support at work, the highest incidence was attributed to Informational Social Support, and the lowest priority was assigned to Emotional Social Support. Furthermore, the multiple regression analysis revealed that the model with greater explanatory power was represented by the General Support variable, whose variance was explained in 45,6 percent by the factors Autonomy and Achievement, Prestige, and Domain(AU)
