Social distance among health professionals toward the substance dependence

The attribution of undesirable characteristics to a person may lead to rejection and social distance. This study aims to evaluate differences on desire for social distance related to dependents of marijuana, alcohol and cocaine, among health professionals from Juiz de Fora, Minas Gerais, Brazil. Relation between desire for social distance and the professionals socio-demographics characteristics was also availed. The results demonstrated greater social distance related to cocaine dependents and no significant difference between the scores for marijuana and alcohol dependents. Social distance judgements were not significantly correlated to any socio-demographics characteristics but professional level, that correlated with dependent of alcohol scores. Studying social distances may contribute to the implementation of strategies that may lead to services improvement.A atribuição de características indesejáveis a alguém pode conduzir à rejeição da pessoa rotulada, ocasionando o distanciamento social. O presente estudo teve como objetivos, avaliar as diferenças entre o desejo de distanciamento social dos profissionais de saúde da cidade de Juiz de Fora-MG, Brasil, em relação aos dependentes de álcool, maconha e cocaína, e possíveis relações entre o desejo de distanciamento social em cada um dos casos e variáveis sociodemográficas desses profissionais. Os resultados demonstraram que o distanciamento social foi maior para o dependente de cocaína, não havendo diferença significativa entre os escores das escalas para dependentes de álcool e maconha. Os julgamentos de distância social foram independentes de qualquer característica sociodemográfica da amostra, com exceção do aspecto nível profissional em relação ao dependente de álcool.

Preparation of the orgamomodified cellulose acetate membranes for adsorption of the ions Cu(II), Cd(II), Mn(II) AND Ni(II)

Cellulose acetate polymeric membranes had been prepared by a procedure of two steps, combining the method of phase inversion and the technique of hydrolysis-deposition. The first step was the preparation of the membrane, and together was organomodified with tetraethylortosilicate and 3-aminopropyltrietoxysilane. Parameters that exert influence in the complexation of the metallic ion, as pH, time of complexation, metal concentration, had been studied in laboratory using tests of metal removal. The membranes had presented resistance mechanics and reactivity to cations, being able to be an alternative for the removal, daily pay-concentration or in the study of the lability of metals complexed

Uma breve análise exegética de Nm 10,29-32

The Book of Numbers does not seem to receive the same attention as the other books of the Torah. There are good comments, but few articles. In this sense, a study on Nm 10,29-32 may bring some contribution, in particular on the subject of supplication with a promise of reward that is no stranger to the book. In the text in focus, there is the dialogue between Moses and Hobab, on the iminence of the departure from Sinai towards Canaan. Moses asks Hobab to serve as a guide in the crossing of the desert. The bond, the denomination of Moses' father-in-law and the usefulness attributed to him are relevant and crafted questions in the analysis, also asking about the divine presence as a guide through the desert by the Ark of the Covenant and the Cloud. If YHWH is already the guide, why the supplication for a member of the Raguel clan of the Madianites to direct them through desert routes? This article, adopting diachronic and sinchronic approaches, is subdivided into segmented translation and notes of textual criticism, delimitation, structure and literary genre, followed by a comment to the sections adopted. Nm 10,29-32 attests that human expertise does not nullify the divine conduction, but integrates it.O Livro de Números parece não receber a mesma atenção que os demais livros da Torá. Existem bons comentários, mas poucos artigos. Nesse sentido, um estudo sobre Nm 10,29-32 pode trazer alguma contribuição, em particular sobre o tema da súplica com promessa de recompensa que não é estranho ao livro. No texto em foco, encontra-se o diálogo entre Moisés e Hobab, na iminência da partida do Sinai rumo a Canaã. Moisés pede que Hobab sirva de guia na travessia pelo deserto. O vínculo, a denominação do sogro de Moisés e a utilidade a ele atribuída são questões relevantes e trabalhadas na análise, indagando ainda sobre a presença divina como guia pelo deserto através da Arca da Aliança e da Nuvem. Se YHWH já é o guia, por que a súplica para que um membro do clã de Raguel dos madianitas lhes direcione pelas rotas do deserto? Este artigo, adotando abordagens diacrônicas e sincrônicas, subdivide-se em tradução segmentada e notas de crítica textual, delimitação, estrutura e gênero literário, seguido de um comentário às seções adotadas. Nm 10,29-32 atesta que perícia humana não anula a condução divina, mas a integra

Effect of 2% chlorhexidine treated coronal dentin on bond strength of two self-adhesives cements

Despite advances in adhesive dentistry, lasting bonds between indirect restorations and dentin remain a challenge. Objective: Therefore, the aim of this study was to evaluate the effect of chlorhexidine on the bond strength of self-adhesive cements to dentin after storage for 24 h and 90 days. Material and methods: Forty-eight human third molars crowns were included in polyvinyl chloride matrices using acrylic resin and worn to expose a flat dentin area. The specimens were randomly distributed into 8 groups (n = 12) in accordance with the self-adhesive cement (Rely X U200 and Smart Cem 2), the dentin treatment (application or not of 2 % chlorhexidine digluconate solution for 1 min) and the storage period (24 h or 90 d). Two cylinders’ cements (1.4 x 1 mm) were constructed on the dentin surfaces of each sample, stored in distilled water for 24 h or 90 days and submitted to a micro-shear test. Subsequently, a failure analysis was performed to classify the failure into adhesive, cohesive, and mixed. Data were subjected to ANOVA and Tukey (0.05) tests. Results: There was a statistically significant difference between the materials (Rely X U200 > Smart Cem 2 – p < 0.05) regardless of the surface treatment and the storage period. Conclusion: The chlorhexidine application did not affect the immediate or delayed bond strength values, regardless of the self-adhesive cement

Surface topography and bacterial adhesion of CAD/CAM resin based materials after application of different surface finishing techniques

Aim: This study evaluated the surface topography and bacterial adhesion of a hybrid ceramic and a nano ceramic resin composite after different surface finishes. Methods: Hybrid ceramic (Vita Enamic, VITA - EN) and nano ceramic resin composite (Lava Ultimate, 3M/ESPE - LV) blocks of 12 x 14 x 18 mm were cut into 1 mm slices. Each slice was divided into four specimens (6 x 7 mm) that were randomly allocated into 4 groups (n=8) according to the surface finishing: CTL - without surface finish (control); DB - wear with a diamond bur; VT - polishing system for hybrid ceramic (VITA); and DD - polishing system for ceramics (Dedeco). The specimens were analyzed regarding surface roughness parameters (Ra, Rz, Rq), sterilized and subjected to bacterial adhesion. Representative specimens from each group were observed by SEM and Confocal Laser Scanning Microscopy. Data were submitted to two-way ANOVA and Tukey's test (α=0.05). Results: EN had lower surface roughness and bacterial adhesion than LV (p&lt;0.05), regardless of the surface finish. The highest values for all roughness parameters was observed in LVDB group, differing from the other groups, which were not significantly different. Smaller bacterial adhesion values (CFU/mL) were observed for ENDD and ENVT, which differed significantly from the other groups, except ENCTL. For LV groups there was no significant difference between the different surface finishes (p&gt;0.05). The type of material and surface finish system significantly interfered with surface roughness parameters and bacterial adhesion. The hybrid ceramic performed better after polishing than the nano-ceramic resin. Conclusion: An adequate finishing/polishing technique should always be performed after any kind of adjustment to indirect restorations made with these materials tested
