Aim To assess the children's perceptions of the dentist's attire and environment. The protocol is available in the PROSPERO database. Search strategies Systematic searches in the databases were performed in Cochrane, Latin American and Caribbean Health Sciences, PubMed, PsycINFO, Scopus, and Web of Science from their inception to December 12, 2019, Google Scholar, Open Grey, and ProQuest Dissertations. Selection criteria Criteria consisted of descriptive studies regarding the above matter while two authors assessed the information. The risk of bias was also performed. Results Databases showed 1,544 papers and a two-phase assessment selected 21 studies in narrative and 9 in the quantitative synthesis. A meta-analysis demonstrated no difference between white coat and child-friendly attire (OR = 0.63; 95% CI 0.16-2.49; n = 3,706) and a decorated vs plain dental clinic was the preference of the children's majority (OR = 8.75; 95% CI 1.21-63.37; n = 150). Conclusion It can be concluded that there is no difference in the children's perception, white coat vs child-friendly attire; however, children prefer a decorated dental clinic.

Malignant neoplasms may be composed of several cell groups, including cancer stem cells (CSC). These cells have been related with the capacity of metastasis, relapse and resistance to multiple drugs during chemotherapy. This study aims to identify CSC biomarkers and their expression pattern in human head and neck carcinomas. This study was conducted following the PRISMA checklist. The search for articles was carried out in five databases (PubMed, Scopus, Web of Science, Lilacs and Scielo). The articles found were selected in two phases: 1) reading the titles and / or abstract and 2) reading the full text. At the end, the selected articles were evaluated by QUADAS-2. Most studies evaluated oral neoplastic tissues and, as a control, samples of normal local mucosa. All studies performed immunohistochemistry as a method of immunolocalization and some also applied immunofluorescence. The most commonly used biomarker was CD44. However, other such as Sox2, Oct4, Nestin, Nanog, BMI1, ALDH1, CD133 and CD166 were also found. Several biomarkers were (ALDH1, Sox2, Oct4, ABCB5, AGR2 and TAZ) correlated with clinical characteristics of the tumor, such as staging, tumor size and lymph node metastasis. These data reinforce the CSC theory and favor the use of these biomarkers as possible determinants of prognosis.

Relato de pesquisa que aborda as necessidades informacionais e o uso de informação dos médicos residentes, na prática clínica. Contextualiza a pesquisa realizada no Hospital Universitário da UFSC, que teve como participantes os médicos residentes. Levanta as necessidades informacionais na prática clínica dos médicos residentes, que atuam nos ambulatórios do hospital. Mapeia o processo de escolha das fontes de informação e indica as mais utilizadas. Os resultados mostram que: durante sua prática ambulatorial, o médico residente se depara com questões classificadas como foreground, mais ligadas a aspectos clínicos do tratamento do paciente, em detrimento de questões ligadas a aspectos básicos, tais como epidemiologia e etiologia; utilizam como principais fontes de informação: periódicos, textbooks e handbooks, guidelines e preceptores, quase que de maneira equitativa; a Internet foi o meio mais utilizado na busca de informação; dentre os sistemas informatizados utilizados com frequência, destacam-se: UptoDate, Portal de Periódicos da CAPES e PubMed/Medline. Os resultados permitem inferir que os médicos residentes estão conscientes da importância do uso da informação para uma melhor prática clínica. This paper describes the study of information requirements and use of information by resident physicians in clinical practice. It contextualizes the study undertaken at UFSC University Hospital of resident physicians and outlines the information requirements in clinical practice by the resident physicians in the hospital. It then maps the process of choosing the information sources to be used and shows those most widely used. The results suggest that: in the course of their work resident physicians are faced with issues classified as foreground issues which are more connected with the clinical aspects of patient treatment, to the detriment of issues connected with basic aspects such as epidemiology and etiology; for their main sources of information they use periodicals, textbooks and handbooks, guidelines and other manuals in an almost equal way; the internet was the most used method for information searches; within those information systems the most used were: UptoDate, the CAPES journal portal and PubMed/Medline. These results suggest that the resident physicians are aware of the importance of information use for more efficient clinical practice.

Resumo Pesquisa que analisa o fluxo da informação na prática clínica dos médicos residentes. Para tal, considera os preceitos da medicina baseada em evidências (MBE) e elege como lócus de pesquisa o Hospital Universitário da UFSC e como universo os médicos residentes atuantes nos seus ambulatórios. A relevância do desenvolvimento da pesquisa está amparada em alguns argumentos: reconhecimento da MBE na prática clínica como alternativa para dar suporte à decisão clínica, através da seleção das fontes de informação de maior evidência disponíveis na literatura médica; constatação que há lacuna na literatura nacional para estudos com médicos residentes, uma vez que a maioria das pesquisas enfoca a forma como médicos e professores da área de saúde usam os sistemas e serviços de informação; convicção que o uso de informação selecionada de forma criteriosa possibilitará uma prática clínica mais eficaz. A pesquisa identificou e analisou os processos envolvidos no fluxo informacional na prática clínica do médico, sob as perspectivas de seleção, acesso, recuperação e uso das fontes de informação. Apresenta um modelo de fluxo de informação ideal na perspectiva da MBE. Palavras-chave Fluxo da informação. Medicina baseada em evidências. Acesso à informação. Information flow in the clinical practice of resident physicians: an analysis from an evidence-based medicine perspective Abstract This study analyses information flow in the clinical practice of resident physicians. To this end it considers the precepts of Evidence Based Medicine (EBM), and focuses on resident physicians at UFSC University Hospital medical clinics. The relevance of this research project is underpinned by several reasons: the recognition of EBM in clinical practice as an alternative that can support clinical decisions, through the selection of information sources of greater evidence available in medical literature; verification that there is a lack of studies on resident physicians in the national literature - the majority of studies have focused on the manner that physicians and professors in health fields use the information systems and services; the conviction that the use of information selected according to criteria encourages more efficient clinical practice. This study identifies and analyses the processes involved in information flow in clinical practice by physicians from the perspectives of selection, access, retrieval and use of information sources. It presents an ideal model of information flow from the perspective of EBM. Keywords Information flow. Evidence Based Medicine. Information access.

Background The aim of this systematic review and meta-analysis was to assess the prevalence of clinical signs of temporomandibular joint (TMJ) disorders in children and adolescents. Type of Studies Reviewed The authors selected only studies in which the investigators' primary objective was to evaluate the prevalence of signs of TMJ disorders according to the international Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) in children and adolescents. The authors performed electronic searches without language restriction in 5 databases. The authors also assessed quality. Results In this review and meta-analysis, the authors included 11 articles that described studies in which 17,051 participants had been enrolled. The overall prevalence of clinical signs of intra-articular joint disorders was 16% (95% confidence interval [CI], 11.59-19.94; n = 17,051). The prevalence of TMJ sounds (click and crepitation) was 14% (95% CI, 9.67-19.79; n = 11,316). The most prevalent sign was clicking (10.0%; 95% CI, 7.97-12.28; n = 9,665) followed by jaw locking (2.3%; 95% CI, 0.56-5.22; n = 5,735). Conclusions and Practical Implications One in 6 children and adolescents have clinical signs of TMJ disorders. The results of this systematic research study can alert dentists about the importance of looking for signs of TMD in children and adolescents.
