No full textBackground CDEUSSA is a Specific Support Action project from the Sixth Framework Programme Priority of the European Union (EU). Its aim is to bring together basic and applied research in the area of coeliac disease (CD). This paper reviews the main issues that are a result of the CDEUSSA initiative. Aim To identify the major issues in need of investigation in the areas of clinical aspects, treatment, prevention and public health. Methods Key stakeholders, representing a wide range of knowledge with crucial importance for CD research and practice, have participated in two workshops aimed at identifying and proposing to the EU, as high priority research, topics in the areas of clinical aspects, treatment, prevention and public health. Results In public health, the overall goal should be to improve quality of life of the European population by implementing primary prevention strategies, early diagnosis and improved treatments for CD. New treatment strategies need to be developed. The option of primary prevention should be fully explored, which requires combined epidemiological, clinical and basic scientific research efforts. Such studies should also consider the importance of gene–environment interactions in the development of CD. Increased knowledge is needed on the natural history of CD. Diagnostic criteria need to be revised. Conclusions To achieve these goals, a collaboration of the stakeholders is fundamental, including research and patient organizations, as well as industries within both diagnostics and food productio
Systematic review with meta-analysis: early infant feeding and celiac disease - update 2015.
No full textBACKGROUND:
New evidence emerged on early feeding practices and the risk of coeliac disease.
AIM:
To systematically update evidence on these practices to find out whether there is a need to revise current recommendations.
METHODS:
MEDLINE, EMBASE and the Cochrane Library were searched from July 2012 (end of last search) to February 2015 for studies of any design that assessed the effect of gluten consumption and breastfeeding on the development of coeliac disease and/or coeliac disease-related autoimmunity.
RESULTS:
We identified 21 publications, including two, new, large, randomised controlled trials performed in high-risk infants. Exclusive or any breastfeeding, as well as breastfeeding at the time of gluten introduction, did not reduce the risk of developing coeliac disease during childhood. For infants at high risk of developing coeliac disease, gluten introduction at 4 months of age in very small amounts, or at 6 or 12 months of age, resulted in similar rates of coeliac disease diagnosis in early childhood. Later gluten introduction was associated with later development of coeliac specific autoimmunity and coeliac disease during childhood, but not total risk reduction. Observational studies indicate that consumption of a higher amount of gluten at weaning may increase the risk for coeliac disease development.
CONCLUSIONS:
Infant feeding practices (breastfeeding, time of gluten introduction) have no effect on the risk of developing coeliac disease during childhood (at least at specific timeframes evaluated in the included studies), necessitating an update of current European recommendations
Dense genotyping identifies and localizes multiple common and rare variant association signals in celiac disease.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
