BEC and APC are both effective for the therapy of bleeding telangiectasias from CRCP. There are probably no major differences between them. Although APC seemed safer than BEC in this investigation, further studies, involving a much larger population, are needed to assess the complication rates and determine the best management option.

This study analyzes research articles about open access (OA) indexed by the Scopus database, published from 2001 to 2015, in order to: (a) propose a categorization scheme about OA; (b) categorize the scientific production about OA; and (c) identify research trends on OA through disciplines at international level over time. The authors used descriptive statistical methods and deductive content analysis using an unconstrained matrix in 347 selected research articles. The most explored themes were found to be "overview, current state, and growth of OA" counting for 98 articles (28.2%), and "awareness, perceptions, and attitudes toward OA" for 75 articles (21.6%). As a conclusion, this study reveals a continuous and growing research interest by the OA community in studies focused on case studies regarding the development or evolution of OA in relation to certain groups, institutions, regions, periods, and how different actors perceive and address the OA movement.

The essential role of journals as registries of scientific activity in all areas of knowledge justifies concern about their ownership and type of access. The purpose of this research is to analyze the main characteristics of publishers with journals that have received the DOAJ Seal. The specific objectives are a) to identify publishers and journals registered with the DOAJ Seal; b) to characterize those publishers; and c) to analyze their article processing fees. The research method involved the use of the DOAJ database, the Seal option and the following indicators: publisher, title, country, number of articles, knowledge area, article processing charges in USD, time for publication in weeks, and year of indexing in DOAJ. The results reveal a fast-rising oligopoly, dominated by Springer with 35% of the titles and PLOS with more than 20% of the articles. We've identified three models of expansion: a) a few titles with hundreds of articles; b) a high number of titles with a mix of big and small journals; and c) a high number of titles with medium-size journals. We identify a high number of titles without APCs (27%) in all areas while medicine was found to be the most expensive area. Commercial publishers clearly exercise control over the scope of journals and the creation of new titles, according to the interests of their companies, which are not necessarily the same as those of the scientific community or of society in general.

<p><strong>Introdução: </strong>A presente pesquisa realiza uma analise das revistas científicas hospedadas no Portal de Periódicos UFSC e sua relação com o estrato nacional Qualis/CAPES e os índices <em>Harzing’s</em> <em>Publish or Perish</em> h e g na web.</p><p><strong>Objetivos: </strong>a) Descrever a área do conhecimento,periodicidade e ano de criação das revistas, e; b) Comparar os indicadores de qualidade Qualis e os índices <em>Harzing’s</em> <em>Publish or Perish</em> h e g das revistas. <strong></strong></p><p><strong>Metodologia: </strong>A abordagem da metodologia é exploratória e descritiva com análise quantitativa.

A periodicidade mais adotada é a semestral, representando 73,8% (31) das revistas. O período de criação das publicações que apresentou maior índice foi a década de 1990, com 42,9% (18). Em relação ao Qualis, 14% das revistas apresentam estrato A1 e A2; 57%, B1 e B2, e 29% das revistas apresentam B3, B4 e B5.</p><p class="Standard"><strong>Conclusões: </strong>Pode-se concluir que as posições das revistas podem ser diferentes se aplicadas ao sistema de avaliação Qualis/CAPES e os índices do h e g. A revista que apresenta maior coerência entre o índice nacional e o índice <em>Harzing’s</em> <em>Publish or Perish</em> é a “Estudos Feministas”, com Qualis A1, índice h 41 e g 63 e a que apresenta menor coerência é a “Outra Travessia” com Qualis A2 e índices h 5 e g 11.</p>

Este artigo trata de Portais de Periódicos Científicos Online em Acesso Livre. Faz uma breve revisão de literatura sobre publicações científicas digitais e analisa os portais de periódicos científicos brasileiros das instituições Federais e Estaduais de Ensino Superior. O objetivo da pesquisa é identificar a situação dos portais de periódicos científicos por meio da análise da inserção institucional, plataforma utilizada e políticas expressas. Com metodologia exploratório-descritiva, a pesquisa utilizou-se da técnica de pesquisa documental com abordagem quantitativa e o método envolveu levantamento, classificação, tabulação e interpretação de dados dos portais e periódicos das 53 Universidades Federais e 36 Universidades Estaduais brasileiras. Como resultado, são apresentados 17 portais, com alto grau de diversidade em suas diretrizes.

Objective: To determine the CT findings of multiple cavitary lung lesions that allow the differentiation between benign and malignant etiologies. Methods: We reviewed CT scans, including patients with two or more cavitary lung lesions. We evaluated the number of cavitary lesions, their location, cavity wall thickness, and additional findings, correlating the variables with the diagnosis of a benign or malignant lesion. Results: We reviewed the chest CT scans of 102 patients, 58 (56.9%) of whom were male. The average age was 50.5 ± 18.0 years. Benign and malignant lesions were diagnosed in 74 (72.6%) and 28 (27.4%) of the patients, respectively. On the C T scans, the mean number of cavities was 3, the mean wall thickness of the largest lesions was 6.0 mm, and the mean diameter of the largest lesions was 27.0 mm. The lesions were predominantly in the upper lobes, especially on the right (in 43.1%). In our comparison of the variables studied, a diagnosis of malignancy was not found to correlate significantly with the wall thickness of the largest cavity, lymph node enlargement, emphysema, consolidation, bronchiectasis, or bronchial obstruction. The presence of centrilobular nodules correlated significantly with the absence of malignant disease (p < 0.05). In contrast, a greater number of cavities correlated significantly with malignancy (p < 0.026). Conclusions: A larger number of cavitary lung lesions and the absence of centrilobular nodules may be characteristic of a malignant etiology. However, on the basis of our evaluation of the lesions in our sample, we cannot state that wall thickness is a good indicator of a benign or malignant etiology.

We report a new case of neuroendocrine carcinoma for which it was not possible to find the primary site until now. The recent medical literature about skin metastasis of neuroendocrine carcinoma (neuroendocrine tumor) is discussed.
