[How to publish in pediatrics journals with impact factor: Role of open access journals]. / Cómo publicar en revistas de impacto en pediatría: papel de las revistas open access.

To publish articles in prestigious scientific journals is not a simple task, particularly because of three main reasons: the difficulty for designing and performing competitive and high quality research, the high rates of rejection in most high-impact journals, and the absence of systematized training in the methodology of biomedical publications in the curricular programs. If to this is added the progressive complexity of the instructions for authors and the formal requirements that most journals impose, it is logical that there is discouragement among potential authors. On the other hand, the pressure and the demand for authorship of scientific articles to be able to get academic and professional positions of a certain level are increasing. However, what at first glance seems a gloomy perspective, it is not so much if some key aspects related to the structure and writing of manuscripts and the systematics of the editorial process of the journals are known and applied, which, in short, continue being in force since the aphorism «publish or perish¼ became popular at the beginning of the last century. As described in this article, the steps to follow are straightforward, logical, and interrelated, so getting off to a good start and completing the various stages properly and in the right order always represents a clear advantage in ensuring the final success of having your paper accepted.

[Common and specific methodological features of checklists]. / Aspectos metodológicos comunes y específicos de las listas de comprobación.

As medical aims, diagnosis, prognosis, intervention and prevention benefit from scientific method, although they have specific characteristics requiring distinct types of design and statistical analysis. The present article aims to provide definitions of the common and differential features of checklists for the main study designs. Distinctions are made between statistical inference and decision, systematic and random error, confirmation and exploration, prediction and intervention, observation and experimentation, and random allocation and random selection. In addition, the main tools available to researchers to control random and systematic errors are described. How all of these elements are contained in the main types of design is discussed. Importantly, checklists are not a measure of the quality of a study but rather represent minimum requirements that aim to improve the quality of scientific reports.
