A IMPORTÂNCIA DE ENSINAR RESISTÊNCIA BACTERIANA NO ENSINO MÉDIO: UMA ANÁLISE DE LIVROS DIDÁTICOS DE BIOLOGIA SELECIONADOS PELO PNLEM/2018

O presente trabalho é fruto de uma pesquisa que investiga o tema da resistência bacteriana e suas relações com o campo do ensino e as discussões que tangem o tema da saúde, gerando o objetivo desta pesquisa: verificar o trato do tema resistência bacteriana, abordada em livros didáticos e sua explanação relativa a importância do uso correto de antibióticos. Para isso, lançamos mão de uma metodologia de cunho qualitativo, empreendendo um estudo descritivo de 10 (dez) livros didáticos de Biologia indicados pelo Programa Nacional do Livro Didático para o Ensino Médio (PNLEM/2018). A análise considerou a presença de quatro critérios: C1- doenças bacterianas e seu tratamento; C2- Resistência Bacteriana; C3- Problematização do tema Resistência Bacteriana; C4- Incentivo as práticas de uso correto de antibióticos. Dos livros analisados 80% estão adequados quanto ao ensino de doenças bacterianas e tratamento.  O tema resistência bacteriana apareceu em 50% dos livros com tópicos extremamente pequenos e explicações rasas. A problematização da resistência bacteriana apareceu em 70% dos livros com número de questões insignificantes. O uso correto de antibióticos apareceu somente em 40% dos livros. Concluímos que se faz necessário a criação de outras formas didáticas para o ensino destas temáticas em sala de aula

Causas gerenciais e ambientais da mortalidade de micro e pequenas empresas: um estudo com empresários de Vitória da Conquista, Bahia

Este artigo trata das causas gerenciais e ambientais da mortalidade dos micro e pequenos empreendimentos nos segmentos do comércio, indústria e serviços, buscando conhecer o perfil dos empresários no intuito de identificar possíveis causas do fechamento de empresas em Vitória da Conquista, Bahia. Foi realizado um estudo de natureza exploratório-descritivo, com abordagem quali-quantitativo. Diante dos resultados identificou-se que as principais causas do fechamento das empresas são decorrentes de deficiências no processo gerencial e de problemas externos à organização

Hyperbaric Oxygen: Therapy for Patients With Maxillofacial Implants?

Osseointegration was an innovative treatment in dentistry during the last 3 decades. The success of osseointegration is related to factors such as material biocompatibility, adequate quality of bone tissue that allows implantation, surgical technique, and macrostructure and microstructure of implant. The osseointegrated implants are successfully applied in dental clinic including oral and facial rehabilitations mainly for patients submitted to mutilating surgeries. However, patients submitted to radiation therapy present risks to treatment with implants owing to adverse effects on bone tissue. Nowadays, the literature suggests different therapies to improve the success of osseointegration such as hyperbaric oxygen therapy that aims to prepare bone and adjacent tissues to receive the implant. Therefore, the purpose of this study was to present a literature review concerning indications, contraindications, successes, and difficulties with hyperbaric oxygen therapy associated to maxillofacial implants

Anti-inflammatory effect of ethanolic extract of Ocimum basilicum L. in the healing process of incisional wounds in mice

881-887Maintaining the structural and functional integrity of the skin is critical to ensure body homeostasis. After damage, a series of cellular and molecular events occurs in this structure in order to repair the injured tissue. Imbalances in one or more repair steps are commonly related to difficulties in proceeding with healing. This has driven the search for natural molecules from plants to improve the repair process that is economical with less side effects. In this context, the common medicinal herb, Ocimum basilicum L., used globally from cooking to practices in folk medicine, has in its phytoconstitution substances with different actions such as anti-inflammatory, antioxidant, antimicrobial. Therefore, in the present study, we have evaluated the anti-inflammatory effect of intraperitoneal treatment with ethanolic extract of O. basilicum (EEOB) on wound healing in mice. Incisional wounds were induced in mice, they were divided according to treatment period and group, n=6, and received EEOB intraperitoneally (i.p.) at 150 mg/kg daily or saline solution for 5 or 7 days. At the end of this period, the animals were euthanized and the lesions underwent histopathological processing and analysis. In animals treated with EEOB injection, there was a decrease in the number of leukocytes at 5 days and mast cells at 7 days post-injury compared to the control. The observed anti-inflammatory action can be attributed to the phenolic compounds and their individual or synergistic effects on the healing process

Fracture resistance and biomechanical behavior of different access cavities of maxillary central incisors restored with different composite resins

Objectives: The aim of this study was to compare the effect of three different access cavities on the tissue removal, deflection, fracture resistance, and stress distribution of extracted maxillary central incisors. Materials and methods: Forty human maxillary central incisors were randomly assigned in four experimental group (n = 10) including conservative access cavity “CAC,” traditional access cavity “TAC,” invasive access cavity “IAC,” and without access cavity (control group). Cone-beam computed tomography “CBCT” scans were used to evaluate the tissue removal during the different access cavities. All specimens were restored with composite resin (Admira Fusion, Voco, Cuxhaven, Germany) and embedded in acrylic resin blocks after simulating the periodontal ligament using red wax, then the specimens were submitted to the deflection test applying a load of 250 N and to the load-to-fracture test after artificial aging in a mechanical cycling machine (150 N, 5 × 106 cycles, 10 Hz). Lastly, stress distribution was assessed by three-dimensional finite element analysis (3D-FEA), simulating the specimens restoration by two types of composite resins of low and high elastic modulus (8 and 18 GPa respectively) after the access cavities. The data were submitted to Shapiro–Wilk and KS normality tests. Then, they were analyzed by one-way ANOVA and Tukey tests with a significance level (α ≤ 0.05). Results: CBCT scans showed a significant difference of worn tissues in CAC and TAC when compared to the IAC (P < 0.0001). In deflection test, CAC showed lower deformation values than the TAC and IAC. Load-to-fracture test presented no significant difference among the three experimental groups (P = 0.6901). 3D-FEA showed that the more conservative the access cavity, the higher the stress magnitude. Conclusions: CAC promote less worn tissue; however, this does not improve the stress distribution or fracture resistance of endodontically treated maxillary incisors. Clinical relevance: Clinicians should reconsider the pros and cons of the conservative access cavity
