Journal impact factors have become an important criterion to judge the quality of scientific publications over the years, influencing the evaluation of institutions and individual researchers worldwide. However, they are also subject to a number of criticisms. Here we point out that the calculation of a journal’s impact factor is mainly based on the date of publication of its articles in print form, despite the fact that most journals now make their articles available online before that date. We analyze 61 neuroscience journals and show that delays between online and print publication of articles increased steadily over the last decade. Importantly, such a practice varies widely among journals, as some of them have no delays, while for others this period is longer than a year. Using a modified impact factor based on online rather than print publication dates, we demonstrate that online-to-print delays can artificially raise a journal’s impact factor, and that this inflation is greater for longer publication lags. We also show that correcting the effect of publication delay on impact factors changes journal rankings based on this metric. We thus suggest that indexing of articles in citation databases and calculation of citation metrics should be based on the date of an article’s online appearance, rather than on that of its publication in print.

Anorectal malformations (ARMs) without fistula occur in approximately 5 % of all cases of ARM. The high frequency of Trisomy 21 associated to this type of malformation has been previously described. A review of the literature revealed only one previous publication discussing ARM without fistula with or without Trisomy 21; all other publications focused their discussion in patients with Trisomy 21. We felt that ARM without fistula has very specific characteristics and therapeutic implications that deserved a special discussion, which prompted us to review our experience.

Bibliometric and Altmetric analyses highlight key publications, which have been considered to be the most influential in their field. The hypothesis was that highly cited articles would correlate positively with levels of evidence and Altmetric scores (AS) and rank.

The scholarly publication landscape is changing rapidly. We investigated whether the introduction of an institutional publications officer might help facilitate better knowledge of publication topics and related resources, and effectively support researchers to publish.

Study publication bias and outcome reporting bias have been recognised as two threats to the validity of systematic reviews. The purpose of this research was to estimate the proportion of missing participant outcome data from randomised controlled trials (RCTs) due to lack of publication of whole studies and due to outcome data missing within study publications.

To provide clarity on the professional medical writer as author or contributor by examining what “a substantial contribution” and “accountability” mean with respect to authorship in a biomedical publication. These terms relate to criteria 1 and 4 of the International Committee of Medical Journal Editors (ICMJE) authorship guidelines.

 Plant-based test systems have been described as a useful tool for investigating possible effects of homeopathic preparations. The last reviews of this research field were published in 2009/2011. Due to recent developments in the field, an update is warranted. Publications on plant-based test systems were analysed with regard to publication quality, reproducibility and potential for further research.

Sleeping Beauties (SBs) are publications that are scarcely cited in the years immediately following publication but then suddenly become highly cited later. Such publications have unique citation patterns and can reveal important developments in the field in which they appear.

Understanding semantic relatedness and similarity between biomedical terms has a great impact on a variety of applications such as biomedical information retrieval, information extraction, and recommender systems. The objective of this study is to examine word2vec’s ability in deriving semantic relatedness and similarity between biomedical terms from large publication data. Specifically, we focus on the effects of recency, size, and section of biomedical publication data on the performance of word2vec.

Objectives (1) Evaluate peer-reviewed publications regarding education in otolaryngology since 2000. (2) Analyze publication trends as compared with overall otolaryngology publications. Study Design Bibliometric analysis. Setting Academic medical center. Subjects and Methods A search for articles regarding education in otolaryngology from 2000 to 2015 was performed with MEDLINE and EMBASE databases, yielding 1220 articles; 362 relevant publications were categorized by topic, subspecialty, subject, article type, and funding source. Impact factors for each journal by year were obtained, and trends of each category over time were analyzed. These were then compared with publication numbers and impact factors for all otolaryngology journals. Results From 2000 to 2015, publications in otolaryngology education increased more rapidly than the field of otolaryngology overall. The most published topics included operative skills training, surgical simulation, and professionalism/career development. Recently there has been a decline in publications related to residency administration and duty hours relative to other topics. Only 12.2% of publications reported a funding source, and only 12.2% of studies were controlled. Conclusion Recent trends in otolaryngology literature reflect an increasing focus on education; however, this work is underfunded and often lacks high-quality evidence.
