Statins, antiretroviral therapies, and antiepileptics, followed by immunosuppressants and antithrombotic agents, were the most common therapeutic drug categories. [Implications]: Almost 60% of the generics detailed in studies indexed in MEDLINE were acting on the cardiovascul…
Residents'corner April 2014. Editorial: what's new this month?
2014
In this issue of the European Journal of Dermatology, Bircher et al.[1] revisit tolerance induction in drug hypersensitivity reactions, which is a controversial issue, particularly in delayed hypersensitivity reactions. Drug hypersensitivity may present as a mild, moderate or severe life-threatening reaction, becoming a problem for many patients when the offending drug is essential (and even irreplaceable).Determining which drug is responsible for the reaction may be challenging, especially in multiple [...]
Co-Citation Analysis of Articles Published in Substance Abuse Journals: Intellectual Structure and Research Fields (2001-2012).
2016
The purpose of this study is to introduce a new methodology in the field of substance abuse, namely, co-citation analysis, which uses the bibliographic references of publications to establish the main thematic areas being researched and to identify the seminal documents that have contributed to establishing the intellectual foundation of the discipline at the present time.We identified all bibliographic references that were cited in documents published in the substance abuse journals included in the Journal Citation Reports in the 2001-2012 period, generating a co-citation matrix. This matrix was used to perform a co-citation network analysis.The co-citation network analysis led to the iden…
Confidence Interval or P-Value?: Part 4 of a Series on Evaluation of Scientific Publications
2009
An understanding of p-values and confidence intervals is necessary for the evaluation of scientific articles. This article will inform the reader of the meaning and interpretation of these two statistical concepts.The uses of these two statistical concepts and the differences between them are discussed on the basis of a selective literature search concerning the methods employed in scientific articles.P-values in scientific studies are used to determine whether a null hypothesis formulated before the performance of the study is to be accepted or rejected. In exploratory studies, p-values enable the recognition of any statistically noteworthy findings. Confidence intervals provide informatio…

El Gran rescate de la prensa española: los anticipos reintegrables durante la Primera Guerra Mundial
2021
Resumen La crisis económica que se derivó de la Primera Guerra Mundial provocó, entre otros efectos, la caída aguda de los resultados económicos de la prensa española y una amenaza real de colapso generalizado. Reconvertida a grandes empresas, con exponentes como el primer trust periodístico español, creado en 1906, los editores de periódicos plantearon por primera vez un dilema clave para el sistema representativo: si se quería que existiese prensa, el tesoro público debía colaborar mediante subvenciones a la compra de papel. Se puso en marcha, de esta forma, el primer gran rescate de la prensa española, con una aportación millonaria de dinero público a empresas privadas que, en teoría, te…
Vaakakupissa vaarat ja vastuu: Julkisen palvelun median arvot sosiaalisen median alustojen paineessa
2021
Sosiaalisen median alustat ovat muovanneet media-alan prosesseja ja käytäntöjä merkittävästi. Alustayritysten toimintaa ohjaavat erilaiset arvot ja tavoitteet kuin mediaorganisaatioita, mikä aiheuttaa toimijoiden välille ristiriitaa. Toimintatavoistaan ja arvoistaan sosiaalisessa mediassa joutuvat neuvottelemaan erityisesti julkisen palvelun mediayhtiöt, joiden peruskivenä ovat julkisen palvelun arvot. Tarkastelemme tässä artikkelissa suomalaisen julkisen palvelun mediayhtiön Yleisradion alustasuhdetta laadullisen haastatteluaineiston avulla. Kysymme, miten Yleisradiossa kuvataan ja perustellaan suhdetta sosiaalisen median alustoihin ja minkälaiseen arvopuheeseen suhteen kuvaaminen kytkeyty…
