The Brazilian scientific production saw more than a four-fold increase from the 1990s onwards. The aim of this study was to evaluate the evolution of scientific production by Brazilian clinical neuroscientists over the last 10 years. A search in the PubMed identified 295 clinical neuroscientists and their publications. Brazilian production corresponded to 2.37% of the papers published by the 20 indexed periodicals that regularly publish clinical neuroscience research. If only the first and last two years are compared, there was a real growth of 75.1%. More than 40% of the Brazilian papers were published in Arquivos de Neuro-Psiquiatria, the official journal of the Brazilian Academy of Neurology. When only those periodicals with impact factor higher than one are considered, the percentage falls to 0.86% in the whole 10-year period, but attains 1.23% in 2004. Epilepsy and infectious diseases were the sub-areas with the highest scientific production.

In the last few years, bibliometric studies have proliferated, seeking to provide data on world research. This study analyzes the profile of the Brazilian scientific production in the A (H1N1) influenza field between 2009 and 2011. The research was conducted in MEDLINE, SciELO and LILACS databases, selecting papers in which the term "H1N1" and "Brazil" were defined as the main topics. The data were analyzed taking into consideration the Brazilian state and institution in which the articles were produced, the impact factor of the journal and the language. The research revealed 40 documents (27 from MEDLINE, 16 from SciELO and 24 from LILACS). The journal impact factor ranged from 0.0977 to 8.1230. A similar amount of articles were written in English and Portuguese and São Paulo was the most productive state in the country, with 95% of the Brazilian production originating from the Southern and Southeastern regions. Linguistic data indicate that previous efforts made in order to improve the scientific production of Brazilian researchers making their observations attain a broader scientific audience produced results. It is necessary to assess the scientific studies, especially those conducted with public funds, in order to ensure that the results will benefit society.

Dear Readers, Having served as Editor-in-Chief of Journal of Molecular Endocrinology for seven years, I would like to take this opportunity to thank all those who have contributed to the journal's success – the Editorial Board, authors and referees.Following a great increase in the journal's impact factor in the early part of my term of office, submissions to the journal began to increase significantly, approaching a remarkable 250% of what they had been previously. This gave us the opportunity to build upon the journal's established reputation by improving its high quality standards even further. One of the ways of achieving this was to increase the rejection rate. Prior to 2000, the acceptance rate of the journal had typically been around 60% for many years. In recent years, this percentage has often been in the thirties. Despite this, the number of papers published in a year has frequently been more than it was historically, and rapid growth from one year to the next has sometimes had the effect of temporarily decreasing the journal's impact factor compared with the heights we had previously achieved, because of the way it is calculated. We have also increased the journal's online frequency to monthly, ensuring that the journal is poised ready for the rapid publication of greater numbers of higher quality papers.With this legacy, I am pleased to hand over the reins of the journal to Professor Anna Spada, and I wish her well in taking the journal to new heights.As the incoming Editor-in-Chief of the Journal of Molecular Endocrinology, I feel proud to be associated with a major international journal dedicated to publishing excellent science in the field of molecular endocrinology. Together with the new members of the Editorial Board, we are committed to continue the tradition of excellence established by our predecessors. We would like to take this opportunity to thank the outgoing Editor-in-Chief, Professor Evan Simpson, who contributed greatly to the development and prestige of the journal during his tenure. We would also like to acknowledge with gratitude the efforts of all the other members of the Editorial Board who are retiring.As we enter the year 2008, the journal begins its 20th year of serving the global endocrine community as a vital forum for research on molecular endocrinology. Moreover, the journal recently became an official journal of the European Society of Endocrinology, a fact that confirms its increasing significance and importance. The journal has an active Editorial Board who represent both the global reach of the journal and the breadth of expertise needed to build upon its current subject coverage.Journal of Molecular Endocrinology has undergone substantial developments recently, including full migration to an electronic manuscript handling system and monthly online publication, together with immediate publication of authors' accepted manuscripts. These changes, together with the hard work of the staff of the Society for Endocrinology, the journal's publisher, have had a major impact on the efficiency of manuscript handling, with rapid and careful decisions on submitted manuscripts. High-profile review articles are freely available to all on the web and the improved features of the new platform, including toll-free reference linking and ‘This article has been cited by…’ links to and from other major journals, have increased JME's online visibility.We are committed to publishing the best endocrine research at the molecular level, and we believe that the journal has a particular role in integrating basic molecular mechanisms towards understanding the physiological and pathological processes of the endocrine system. We want to encourage the submission of manuscripts that expand our knowledge of the molecular mechanisms underlying hormone action; examples of potential topics include proteomics, structural features of RNA and the impact on mRNA regulation and processing, DNA repair mechanisms underlying endocrine disorders and cancers, DNA–protein complexes and chromatin structures and the accessibility of promoter–regulatory regions, molecular chaperones, etc. Articles on molecular endocrinology with potential translational/clinical significance, methodology and bioinformatics tools are especially welcome. We also want to attract papers from leaders in other fields who are investigating endocrine-related aspects but do not traditionally publish in our journal. A series of mini-reviews will address a wide range of provocative and updated topics that we believe will extend our range of interest and will aim to anticipate the future direction of many specific research areas. As many of the mini-reviews will be invited, we welcome suggestions of topics and authors as well as outlines of potential mini-reviews from interested authors.It is with a good deal of humility that I take over the reins of the journal. It is my intention to ensure that it remains at the forefront of endocrine research and, along with the Editorial Board, we are hopeful that we can raise JME's standards even higher.

Scientific production is often explored at broader scales but understanding whether regional trends follow global ones is an important issue for science and public policies. Using freshwater fish papers’ production in the Goiás State, Central Brazil, we tested two hypotheses: i) regional production of papers follows global tendencies; ii) regional production is driven by the number of authors, institutions, financial support and dissertations/thesis produced. From published papers we extracted the: year of publication, authors’ institution, journal of publication, impact factor and financial support. To test both hypotheses we performed, respectively, a Pearson correlation between papers number and year, and a multiple linear regression considering papers number or impact factor as response variable and authors, institutions, financial support and dissertations/thesis as predictors variables. We observed a positive correlation between papers number and year, whereas financial support, institutions and dissertation/thesis were the main drivers for papers number and impact factor. Regional production of fish papers follows global patterns of production (financial support and institutions number as mains drivers). However, this production remains influenced by particularities such as: an inconstant production through time and the fact that many papers are still published in journals without an impact factor.

Emotions affect our decisions, experiences, preferences, and perceptions. Understanding the neural underpinning of human emotions is a fundamental goal of neuroscience research. Moreover, EEG-based emotion recognition is a key component towards the development of affective-aware intelligent systems. However, characterizing the neural basis of emotions elicited during video viewing has been proven a challenging task. In this paper, we propose a novel machine-learning approach to isolate neural components in EEG signals that are informative of the affective content of emotionally-loaded videos. Based on these components, we define a set of neural metrics and evaluate them as potential indicators of the overall emotional content of each video. We demonstrate the predictive power of the proposed metrics, on the DEAP benchmark dataset for EEG-based emotion recognition. Our results provide novel empirical evidence that the neural components extracted by our method can serve as an informative metric in EEG-based emotion recognition during video viewing and achieving a 4-fold increase in predictive power compared to traditional frequency-based metrics. Moreover, each extracted component is associated with a spatial and a temporal profile, that allows researchers to inspect and interpret the spatiotemporal origins of the underlying neural activity. Thus, our method a framework that facilitates the study of neural correlates of emotion during video viewing.

Abstract Background: Overviews synthesising the results of multiple systematic reviews help inform evidence-based clinical practice. In this first of two companion papers, we evaluate the bibliometrics of overviews, including their prevalence and factors affecting citation rates and journal impact factor.Methods: We searched MEDLINE, Epistemonikos and Cochrane databases. We included overviews that: (a) synthesised reviews, (b) conducted a systematic search, (c) had a methods section, and (d) examined a healthcare intervention. Multivariate regression was conducted to determine the association between citation density, impact factor and 6 predictor variables. Results: We found 1218 overviews published from 2000 to 2020; the majority (73%) were published in the most recent 5-year period. We extracted a selection of these overviews (n=541; 44%) dated from 2000 to 2018. The 541 overviews were published in 307 journals; Cochrane Database (8%), PLOS ONE (3%) and Sao Paulo Medical Journal (2%) were the most prevalent. The majority (70%) were published in journals with impact factors between 0.05 and 3.97. We found a mean citation count of 10 overviews per year, published in journals with a mean impact factor of 4.4. In multivariate analysis, overviews with a high number of citations and impact factors had more authors, larger sample sizes, were open access and reported the funding source. Conclusions: An 8-fold increase in the number of overviews was found between 2009 and 2020. We identified 332 overviews published in 2020, which is equivalent to 1 overview published per day. Overviews perform above average for the journals in which they publish.
