2013 Update in addiction medicine for the generalist.

Increasingly, patients with unhealthy alcohol and other drug use are being seen in primary care and other non-specialty addiction settings. Primary care providers are well positioned to screen, assess, and treat patients with alcohol and other drug use because this use, and substance use disorders, may contribute to a host of medical and mental health harms. We sought to identify and examine important recent advances in addiction medicine in the medical literature that have implications for the care of patients in primary care or other generalist settings. To accomplish this aim, we selected articles in the field of addiction medicine, critically appraised and summarized the manuscripts, and highlighted their implications for generalist practice. During an initial review, we identified articles through an electronic Medline search (limited to human studies and in English) using search terms for alcohol and other drugs of abuse published from January 2010 to January 2012. After this initial review, we searched for other literature in web-based or journal resources for potential articles of interest. From the list of articles identified in these initial reviews, each of the six authors independently selected articles for more intensive review and identified the ones they found to have a potential impact on generalist practice. The identified articles were then ranked by the number of authors who selected each article. Through a consensus process over 4 meetings, the authors reached agreement on the articles with implications for practice for generalist clinicians that warranted inclusion for discussion. The authors then grouped the articles into five categories: 1) screening and brief interventions in outpatient settings, 2) identification and management of substance use among inpatients, 3) medical complications of substance use, 4) use of pharmacotherapy for addiction treatment in primary care and its complications, and 5) integration of addiction treatment and medical care. The authors discuss each selected articles' merits, limitations, conclusions, and implication to advancing addiction screening, assessment, and treatment of addiction in generalist physician practice environments.

Who wrote the Second Ave maris stella of Tomás Luis de Victoria?

Contrary to what Felipe Pedrell indicates, the second Ave maris stella in his Victoria's collected works (vol. V, 1908, pp. 100-3, n° 33) doesn't appear in the collection published in 1600 in Madrid by the composer, nor in any other of the musician's books. In the 1600 edition, Victoria reissues the two first verses (plainchant followed by polyphony) of the Ave maris stella published in 1576 and then again in 1581. The earliest source of the problematic Ave maris stella is Munich, Bayerische Staatsbibliothek, Musik-Abteilung, 2 Mus. pr. 23 handschriftlicher Beiband, dating from the third quarter oft he seventeenth century. This source is a manuscrit that runs as an appendix to the 1581 edition of Victoria's hymns. No attributions are given in the manuscript. The first attributions of the piece to Victoria arise in the nineteenth century, in manuscripts copied by Johann Michael Hauber, Johann Caspar Aiblinger, August Baumgartner and Carl Proske, and preserved in Munich and Regensburg. Proske pubished the piece in his Musica divina in 1859 (Annus primus, vol. III, pp. 419-24). The most probable hypothesis ist that Pedrell had knowledge of the second Ave maris stella, under the spanish composer's name, via Proske's Musica divina. In all likelihood the piece is not by Victoria, not least because the composer has never written odd polyphonic verses of hymns. In his Studies in the Music of Tomás Luis de Victoria (2001), Eugene Casjen Cramer relies on the supposed authenticity of the work to ascribe the others pieces of Munich, Bayerische Staatsbibliothek, Musik-Abteilung, 2 Mus. pr. 23 handschriftlicher Beiband to the composer. These attributions should therefore be refuted.

Rigor metodológico e investigación filológica

In recent decades, technological advances have made extensive documentation available to us. But the philologist must be aware of the dangers of poor use of the documentary corpus in order to avoid creating dreaded ghost words. In this paper we recall the main sources of this type of error: folk etymology phenomena among speakers, copyists" errors, transcribers" errors in the interpretation of some abbreviations and graphic variants of the manuscripts, onomastic changes introduced by cartographers" ignorance of linguistic variants, gaps in the dating of some documents, confusion in the processes of lemmatization and the evaluation of texts... All these sources of error contribute, to a greater or lesser degree, to the distortion or to the masking of the data on which the research of philologists is based. Hence the importance of philological rigour in the transmission and study of ancient texts.

Catégorisation automatique de propositions textuelles en types de discours

De nombreuses méthodes de classification automatique de textes (supervisée ou non) existent. Elles se sont particulièrement développées depuis la création du web en vue d'améliorer les moteurs de recherche. Au delà de ce champs d'application, elles peuvent aussi être utiles pour « découvrir » ou « redécou­vrir » ce qui caractérise une classe de textes aussi simplement que possible. Dans l'approche statistique développée ici, il s'agira de partitionner des parties de textes en types de discours tels que narratif, explicatif, argumentatif etc. en utilisant un minimum d'information, à savoir les catégories morphosyn­taxiques (CMS). Les premiers résultats obtenus mettent en évidence des liens significatifs entre les CMS, les types de discours et des textes annotés par un expert humain ; ces relations sont toutefois encore incomplètes et difficiles à interpréter d'un point de vue linguistique.

Plegarias iluminadas: libros de horas conservados en bibliotecas catalanas

A través de este texto, pretendemos dar a conocer los libros de horas iluminados conservados en bibliotecas públicas catalanas. Con este fin, se han analizado un total de quince manuscritos, a nuestro juicio los más interesantes desde el punto de vista artístico, localizados en la Biblioteca de Catalunya, Biblioteca de la Universidad de Barcelona, Archivo Histórico de la Ciudad de Barcelona, Museo Episcopal de Vic, Biblioteca del monasterio de Santa María de Montserrat y Biblioteca del Palacio de Perelada. Los libros de horas se han agrupado de acuerdo con su procedencia geográfica: antiguos reinos peninsulares (Corona de Aragón y de Castilla), Francia, repúblicas italianas, Inglaterra y territorios septentrionales del ducado de Borgoña. Cada uno de estos apartados se organiza en torno a una secuencia cronológica que comienza a fines del siglo XIV y concluye hacia el segundo cuarto del siglo XVI.

Evaluación de un artículo científico

El proceso de revisión y evaluación de manuscritos, conocido como arbitraje científico o peer review, supone actualmente un paso que se considera necesario para la divulgación de los avances científicos de una determinada disciplina. Cuando una revista recibe un artículo, sus editores recurren a revisores expertos que, después de la lectura detenida del manuscrito, evalúan la idoneidad de su publicación, en este trabajo se describe el proceso editorial de un artículo y se muestran los ítems por los cuales se evalúan los artículos.

Statistical Reviewers Improve Reporting in Biomedical Articles: a Randomized Trial.

Background. Although peer review is widely considered to be the most credible way of selecting manuscripts and improving the quality of accepted papers in scientific journals, there is little evidence to support its use. Our aim was to estimate the effects on manuscript quality of either adding a statistical peer reviewer or suggesting the use of checklists such as CONSORT or STARD to clinical reviewers or both. Methodology and Principal Findings. Interventions were defined as 1) the addition of a statistical reviewer to the clinical peer review process, and 2) suggesting reporting guidelines to reviewers; with"no statistical expert" and"no checklist" as controls. The two interventions were crossed in a 262 balanced factorial design including original research articles consecutively selected, between May 2004 and March 2005, by the Medicina Clinica (Barc) editorial committee. We randomized manuscripts to minimize differences in terms of baseline quality and type of study (intervention, longitudinal, cross-sectional, others). Sample-size calculations indicated that 100 papers provide an 80% power to test a 55% standardized difference. We specified the main outcome as the increment in quality of papers as measured on the Goodman Scale. Two blinded evaluators rated the quality of manuscripts at initial submission and final post peer review version. Of the 327 manuscripts submitted to the journal, 131 were accepted for further review, and 129 were randomized. Of those, 14 that were lost to follow-up showed no differences in initial quality to the followed-up papers. Hence, 115 were included in the main analysis, with 16 rejected for publication after peer review. 21 (18.3%) of the 115 included papers were interventions, 46 (40.0%) were longitudinal designs, 28 (24.3%) cross-sectional and 20 (17.4%) others. The 16 (13.9%) rejected papers had a significantly lower initial score on the overall Goodman scale than accepted papers (difference 15.0, 95% CI: 4.6- 24.4). The effect of suggesting a guideline to the reviewers had no effect on change in overall quality as measured by the Goodman scale (0.9, 95% CI: 20.3+2.1). The estimated effect of adding a statistical reviewer was 5.5 (95% CI: 4.3-6.7), showing a significant improvement in quality. Conclusions and Significance. This prospective randomized study shows the positive effect of adding a statistical reviewer to the field-expert peers in improving manuscript quality. We did not find a statistically significant positive effect by suggesting reviewers use reporting guidelines.

Historical first descriptions of Cajal-Retzius cells: from pioneer studies to current knowledge

Santiago Ramón y Cajal developed a great body of scientific research during the last decade of 19th century, mainly between 1888 and 1892, when he published more than 30 manuscripts. The neuronal theory, the structure of dendrites and spines, and fine microscopic descriptions of numerous neural circuits are among these studies. In addition, numerous cell types (neuronal and glial) were described by Ramón y Cajal during this time using this 'reazione nera' or Golgi method. Among these neurons were the special cells of the molecular layer of the neocortex. These cells were also termed Cajal cells or Retzius cells by other colleagues. Today these cells are known as Cajal-Retzius cells. From the earliest description, several biological aspects of these fascinating cells have been analyzed (e.g., cell morphology, physiological properties, origin and cellular fate, putative function during cortical development, etc). In this review we will summarize in a temporal basis the emerging knowledge concerning this cell population with specific attention the pioneer studies of Santiago Ramón y Cajal.

Belleza y elocuencia, o la rendición por los sentidos (Lucianus, Scyth. 11)

In Lucian Scythian (§11), all previous editors have corrected the word ¢p£xetai as it appears in the manuscripts to p£xetai. We aim to justify the restoration of the original text because, obviously, it is possible in terms of form, and, besides, it seems more appropriate to the context. The verb ¢p£gomai implies the notion of being moved from one place to another, while p£gomai expresses only the notion of simple attraction which does not involve actual movement. This notion of true surrendering through the senses seems to match the idea developed here by Lucian; loci paralleli in Lucian himself and other Attic authors help us to confirm this interpretation.
