Introduction: Innovation and its processes, especially in the field of technology, are a focus of Information Science as a science of Human, as they determine the establishment of new habits, relevant socio-cultural indicators to understanding the history of cultures. Objective: This article reflects on the problematic: whether and how Information and Communication Technologies have impacted the lives of digital natives, whether the average individual is prepared to conscientiously experience the technological environment, how the current system can prepare future generations of professionals, and how the adults who grew up in the twentieth century, in an analogue society can prepare young people for a twenty-first century digital reality, widely different from theirs. Methodology: This paper was based on Literature Review. Results: As the sophistication of technology advances, society has to continually review the way it appropriates information to adjust to these changes. Conclusions: As for relevance of the methodologies that lead to innovative disruptive actions in hybrid realities such as the Brazilian one, with niches of poverty and prosperity, it is believed that it is in poor countries or countries with significant social differences such as Brazil where the need for a change of socio technocultural paradigm and innovative action urge to take place.

Ante a modernidade, a informação está em toda parte, tornando-se grande o desafio de separar as informações atualizadas das ultrapassadas, as confiáveis das questionáveis e as reais das imaginadas. Em relação aos medicamentos, a despeito dos inegáveis avanços terapêuticos, os produtos farmacêuticos passaram a sofrer uso indiscriminado e irracional. Não se pode negar, que o uso racional de medicamentos implica o conhecimento específico e atualizado sobre os mesmos, como também de profissionais envolvidos e compreensão dos pacientes sobre a importância do tratamento. Na expectativa de se contribuir para dirimir as frequentes dúvidas em relação aos medicamentos, reduzir as ocorrências do surgimento de doenças iatrogênicas e esclarecer ao usuário, conseguindo-se a consciência sobre os riscos da automedicação é que entram em cena os Centros de Informação sobre Medicamentos. Estes são locais, onde se acumulam, organizam, processam, avaliam e se informa sobre medicamentos, com o objetivo de melhorar a saúde. No Brasil, após cerca de 30 anos de experiência em Kentucky, EUA, alguns profissionais e acadêmicos atentaram-se à necessidade e importância da existência de tais Centros. Ante ao exposto, a partir de uma revisão não sistemática da literatura, no presente trabalho foram relatadas a importância, necessidade e desafios para se implementar um Centro de Informação sobre Medicamentos

Descoberta desde 1889 por Hite, a alta pressão hidrostática tem ganhado cada vez mais espaço na indústria de alimentos nos últimos vinte anos. Com todas as vantagens a ela atribuída, essa tecnologia vem para suprir um mercado onde o consumidor exige um alimento seguro e de qualidade cada vez maior. Uma alternativa aos tratamentos térmicos convencionais, a alta pressão hidrostática não somente se sobressai pela sua eficiência tecnológica, oferecendo conservação de atributos sensoriais e nutricionais dos alimentos, como é capaz de proporcionar alimentos seguros microbiologicamente, conferindo uma maior qualidade aos produtos quando comparada a outros tratamentos. Esta revisão sistemática de literatura teve como objetivo discutir a aplicação da alta pressão hidrostática na indústria alimentícia e seu papel como uma tecnologia promissora. A metodologia consistiu em selecionar textos científicos específicos sobre o assunto a partir da pesquisa bibliográfica em banco de dados eletrônicos e livros. Quatro livros e nove textos científicos foram selecionados, entre o período de 2002 e 2014. Conclui-se com esta revisão sistemática de literatura que a alta pressão hidrostática apresenta um futuro promissor na indústria de alimentos. No entanto, pesquisas são necessárias para um estabelecimento de padrões de valores atribuídos ao processo (como pressão, tempo e temperatura, por exemplo) especificamente para cada produto submetido à tecnologia

O exame radiográfico é um procedimento simples e relativamente barato que pode ser utilizado para observação de estruturas ósseas e tecidos moles, incluindo suas alterações, sendo muito empregado em casos de suspeita de aumento de volume ósseo devido a tumores e inflamações. Osteossarcoma e osteomielite, além de causarem a alteração radiográfica acima citada, possuem imagem radiográfica muito semelhante na maioria dos casos, como proliferação e/ou lise óssea, presença do triângulo de Codman e perda do padrão trabecular ósseo, além de sintomas clínicos similares como claudicação e possível presença de fraturas patológicas. A necessidade de se realizar outros métodos de exame complementar paralelos à radiografia é muito importante na determinação de um diagnóstico seguro, o que implica em um tratamento precoce da doença evitando-se assim grande piora no estado geral do paciente. Esta revisão sistemática de literatura visa a comparação radiográfica entre osteomielite e osteossarcoma em cães, para auxilio do médico veterinário na diferenciação de seu diagnóstico.

The changes in the world of work that, in turn, directly affect the teaching work, have expanded the processes of precariousness and intensification, contributing for deteriorating conditions which teachers use to labor. Considering that the time designated for teaching activities is an important part of work conditions, we look for, in this article, to analyze the work shift of teachers in São Paulo state educational public system. Regarding that teachers are a very heterogeneous group, we have chosen to discuss the workday those professionals who dedicate themselves in the last years of elementary and high school. Through a literature review and a research about the legislation related to the topic, in Brazil and São Paulo state, we have highlighted that the teachers’ work shifts should include not only the time for classroom activities, but also for other extra activities. Moreover, we emphasize that the state of São Paulo government has promoted, since 2012, a reformulation of the teachers’ work shift that has not properly include the appropriate length of time for extra educational activities, contrasting the parameters founded in the national legislation. Besides the legal non-compliance, that fact has accentuated the process of intensification of teaching work, contributing for the embrittlement of the collective activities.

Currently it is clear that there are several factors that can act as modifiers of diseases, without causing them directly, but having the potential to make these conditions to progress faster and more severe. There is a growing number of studies investigating the relationship between Diabetes Mellitus (DM) and Periodontal Disease (PD), including some studies focusing on the influence of genetic factors in this process. The aim of this study was to verify through a literature review, the influence of genetic polymorphisms in the development of PD in patients with DM. PubMed and BIREME were used as databases and the terms Periodontitis or Periodontal Disease, Polymorphism, Diabetes Mellitus were searched. After a refinement in the literature, five studies were selected and they were related to chronic PD with DM and polymorphisms in cytokine genes, especially interleukin 1 (IL1) e IL6. Polymorphisms were associated with a higher concentration of pro-inflammatory cytokines in the gingival crevicular fluid of diabetic patients when compared to non-diabetic. In conclusion, it is necessary to confirm this association with longitudinal studies that must investigate a larger number of cytokine genes in order to understand the cause-effect relationship between genetic polymorphisms, DM and PD.

Leishmania is a protozoan belonging to the family Trypanosomatidae, obligate intracellular parasite cells of the mononuclear phagocyte system. In the New and Old World several orders of wild mammals (natural reservoirs) and various species of sandflies (vectors) are involved in the transmission of leishmaniasis. The new settlements in rural areas, changes in the environment and unplanned urbanization increased human contact with vector and interaction with the animal reservoir. A simple prophylactic measure seems to be the vector control as well as disease reservoir. With the goal of raising the prophylactic measures that are being used in vector control, the reservoir of the disease and what the infrastructure accordingly. We conducted a literature review in July 2011 in the electronic databases of Bireme, Medline, CancerLit, Portal Capes, SciELO, PubMed and Medscape, the main texts on the subject. Thus, the development of a vaccine that is effective against various forms of leishmaniasis in the old and new world, it is necessary and has been recommended by WHO as a possible tool for effective eradication of the disease.

Introduction: A variety of hypotheses have been proposed to explain the association between temporomandibular disorders and hearing symptoms, including the many anatomical and/or neurological ways, as of a muscle or joint dysfunction, can cause such symptoms. Objective: The purpose of this study is to discuss, through a systematic review of literature, the interrelation between hearing symptoms and temporomandibular disorders. Material and Methods: We consulted the Medline/PubMed, ISI and Scielo in the period 1918 to 2008. The terms related to the research were: “temporomandibular disorders”, “signs and symptoms of temporomandibular disorders”, “otologic symptoms” and “aural symptoms”, where 19 papers were included using the pre-selected criteria for the manufacture of a meta-analysis. Results: According to the findings, the hearing symptoms most often associated with temporomandibular disorders were otalgia and tinnitus, followed by vertigo and hearing loss, respectively. Conclusions: It’s clear the correlation between hearing symptoms and temporomandibular disorders, however there is a need clinical and scientific research more complex to prove the specific cause-effect relationships between them.
