Abstract Background Scientific publications are important for the advancement in medicine. Surgical disciplines including cardiac surgery are frequently considered not scientifically leading. However, a specific comparison between surgical and nonsurgical disciplines has not yet been performed. We thus compared scientific output of German departments of cardiac surgery with nonsurgical cardiology departments and surgical departments not addressing the heart (general surgery) of 34 universities in Germany. Methods For each university, the personnel working at the different departments were identified on the internet homepage in 2014. We searched for publications of these persons in 2011 to 2013 on PubMed, identified author position, coauthors, and type of article, as well as journal impact factor (JIF). Results There were 931 academic persons in cardiac surgery, 1,486 in general surgery, and 1,814 in cardiology with 12,096 publications related to these persons on PubMed. Cardiology published most manuscripts, including manuscripts from research conducted (first author), initiated (senior author), or both. Cardiac surgery had the least publications and had fewer authors from other departments or institutions. The average JIF was higher in cardiology compared with the two surgical disciplines. However, relating the number of publications to the number of employees in the departments, the differences were no longer apparent. Conclusion We conclude that the number of publications in German universities appears to be a function of the number of academic personnel and not of the discipline. The lower JIFs in surgery may be due to the smaller surgical fields and/or due to less high impact interdisciplinary/interinstitutional publications in surgery.

Abstract Background Research and scientific publications are important for the advancement of science but also for the individual career development. While women have become the majority of students in medicine we do not know about female presence and scientific activity in cardiac surgery. We thus aimed to compare scientific output of women and men in German University departments of cardiac surgery with cardiology departments focusing on the same organ and surgical departments not addressing the heart (general surgery) of 34 universities in Germany. Methods Personnel working at University departments was identified on the institutions internet homepage in 2014. Publications in 2011 to 2013 on PubMed were identified. Author and manuscript characteristics were determined. Results A lower proportion of women were working in cardiac surgery (25%) compared with cardiology (35%) and general (32%) surgery independent of executive function or academic degree. Scientifically active women published fewer manuscripts per capita than men both, in total and as first author. Additionally, the mean and the cumulated journal impact factor of the journals chosen was lower for women compared with men in cardiology but not in cardiac and general surgery. Conclusion We conclude that the differences in scientific activity between women and men are more pronounced in cardiology compared with general and cardiac surgery, indicating that a higher proportion of women in a field does not result in reduced differences between sexes. The low number of women together with the lower number of manuscripts in cardiac surgery may render the appointment of women as directors challenging.

Background: The aim of the research was to acquire knowledge as to how the development of scientific publications looks, while also to specify the scope of research on the area of ski tourism. The research process is concentrated on the following research questions: In what way has the scientific output developed in the field of research on ski tourism? Who is the principal participant (countries, universities, authors, titles of sources) in the accumulation of research in a particular field? Method: In the process of selecting the test sample as a source of bibliometric data the Scopus database was applied. The test sample (N=1500) consisted of publications that contained such phrases in their works as “ski tourism”, “ski hotels”, “ski resorts” in their titles or key words. A general profiling of publications was conducted in order to assess the trends in scientific output and the acknowledgement of the leading co-workers in the field of research. MS Excel was applied for the purpose of supporting the process of analysis and the visualization of results. Results: The analysis indicates that research on ski tourism is one of the aspects of great tradition. This has gained increasingly great interest among academic environments, which led to the breakthrough growth in the number of publications in 2006 indexed in the Scopus database. This publication output encompasses 26 research areas. Conclusions: The principal areas yielding the largest number of publications with regard to ski tourism are to be found in social sciences and science on the environment. The main authors and co-authors in this field are as follows: representatives from the EU and the USA, while the most productive research institution is Universität Innsbruck. The author of the greatest number of publications is Prof. Daniel Scott (University of Waterloo, Canada). The EU is one of the main sponsors.

Scientific Achievements

In recent years, there has been a significant increase in the number of scientific publications. The h-index offers a consistent estimation method about a researcher’s overall scientific achievements since it combines the total number of publications (i.e., productivity) and the number of citations (i.e., quality of those publications). In other words, the h-index is intended to measure simultaneously the quality and quantity of scientific output in a cumulative approach and does not provide data regarding the recent productivity. This editorial presents advantages and limitations of h-index that all researchers in health sciences need to be aware of, especially if this metric is used for professional progression, and discusses the simple modification indexed to “academic/scientific age”. It is obvious that no single metric is perfect, and the use of two or more metrics is more prone to success.

ABSTRACT Evaluation of quality and quantity of publications can be done using a set of statistical and mathematical indices called bibliometric indicators. Two major categories of indicators are (1) quantitative indicators that measure the research productivity of a researcher and (2) performance indicators that evaluate the quality of publications. Bibliometric indicators are important for both the individual researcher and organizations. They are widely used to compare the performance of the individual researchers, journals and universities. Many of the appointments, promotions and allocation of research funds are based on these indicators. This review article describes some of the currently used bibliometric indicators such as journal impact factor, crown indicator, h-index and it's variants. It is suggested that for comparison of scientific impact and scientific output of researchers due consideration should be given to various factors affecting theses indicators.

The purpose of the review is to summarize current literature data and the results of our own research on the analgesic and anti-inflammatory effects of acetylsalicylic acid, as well as the physiological mechanisms underlying them. This acid is the most studied reference representative of salicylates, which is convenient to consider the physiological effects characteristic in general for this group of chemical and medicinal products. Acetylsalicylic acid has analgesic properties against thermal pain and pain caused by electrical stimuli, as well as a pronounced anti-inflammatory effect. The realization of these properties depends on the peculiarities of aspirin metabolism in the body, ion and synaptic mechanisms for controlling the functional state of the cell, neurotransmitter systems of the сentral nervous system, and mechanisms of peripheral and сentral analgesia. Analgesic properties of acetylsalicylic acid founded not only in normal, but also in ultra-small doses. Various physical and especially chemical factors significantly change their effects. This increases the interest in studying the analgesic activity of salicylates and their physiological mechanisms, since such studies can serve as a basis for creating new non-steroidal anti-inflammatory drugs with low toxicity and high safety for patients, and improve the strategy of their practical use. Currently, the most detailed study of the physiological mechanism of analgesic and anti-inflammatory action of aspirin and its main metabolite – salicylic acid. However, it should be note that despite the abundance of existing data obtained in scientific studies of the effects of aspirin and its practical use, there are a number of unexplained aspects of the action of this drug, the mechanism of which has not yet been deciphered. The continuing interest in the effects and mechanisms of action of this drug and in connection with the expansion of its use evidenced by a consistently high number of scientific publications on aspirin in the most famous foreign and domestic publications. At the same time, the number of publications about aspirin is an order of magnitude higher than about any other drug known to humanity.

Abstract Background Antimicrobial resistance (AMR) is a global challenge that requires a “One Health” approach to achieve better public health outcomes for people, animals, and the environment. Numerous bibliometric studies were published on AMR in humans. However, none was published in food-producing animals. The current study aimed at assessing and analyzing scientific publications on AMR in food-producing animals. Method A validated search query was developed and entered in Scopus advanced search function to retrieve and quantitatively analyze relevant documents. Bibliometric indicators and mapping were presented. The study period was from 2000 to 2019. Results The search query retrieved 2852 documents. During the period from 2015 to 2019, approximately 48% of the retrieved documents were published. The article about the discovery of plasmid-mediated colistin resistance in pigs received the highest number of citations (n = 1970). The Journal of Food Protection (n = 123; 4.3%) ranked first in the number of publications while the Applied and Environmental Microbiology journal ranked first in the number of citations per document. The USA led with 576 (20.2%) documents followed by China (n = 375; 13.1%). When the number of publications was standardized by income and population size, India (n = 51.5) ranked first followed by China (n = 38.3) and Brazil (n = 13.4). The growth of publications from China exceeded that of the USA in the last 3 years of the study period. Research collaboration in this field was inadequate. Mapping author keywords showed that E. coli, Salmonella, poultry, Campylobacter, chicken, cattle, and resistant genes were most frequent. The retrieved documents existed in five research themes. The largest research theme was about AMR in Salmonella in food-producing animals. The most recent research theme was about the dissemination and molecular transfer of AMR genes into the environment and among different bacterial strains. Conclusion Hot spots of research on AMR in food-producing animals match the world regions of reported hot spots of AMR in animals. Research collaboration in this field is of great importance, especially with low- and middle-income countries. Data on AMR need to be collected nationally and internationally to implement the “One Health” approach in the fight against AMR.

Purpose This paper aims to answer the question of how the Polish representatives of social communication and media sciences communicate the most recent scientific findings in the media space, i.e. what types of publications are shared, what activities do they exemplify (sharing information about their own publications, leading discussions, formulating opinions), what is the form of the scientific communication created by them (publication of reference lists' descriptions, full papers, preprints and post prints) and what is the audience reception (number of downloads, displays, comments). Design/methodology/approach The authors present the results of analysis conducted on the presence of the most recent (2017–2019) publications by the Polish representatives of the widely understood social communication and media sciences in three selected social networking services for scientists: ResearchGate, Google Scholar and Academia.edu. The analyses covered 100 selected representatives of the scientific environment (selected in interval sampling), assigned, according to the OECD classification “Field of Science”, in the “Ludzie nauki” (Men of Science) database to the “media and communication” discipline. Findings The conducted analyses prove a low usage level of the potential of three analysed services for scientists by the Polish representatives of social communication and media sciences. Although 60% of them feature profiles in at least one of the services, the rest are not present there at all. From the total of 113 identified scientists' profiles, as little as 65 feature publications from 2017 to 2019. Small number of alternative metrics established in them, implies, in turn, that if these metrics were to play an important role in evaluation of the value and influence of scientific publications, then this evaluation for the researched Polish representatives of social communication and media sciences would be unfavourable. Originality/value The small presence of the Polish representatives of the communication and media sciences in three analysed services shows that these services may be – for the time being – only support the processes of managing own scientific output. Maybe this quite a pessimistic image of scientists' activities in the analysed services is conditioned by a simple lack of the need to be present in electronic channels of scientific communication or the lack of trust to the analysed services, which, in turn, should be linked to their shortcomings and flaws. However, unequivocal confirmation of these hypotheses might be brought by explorations covering a larger group of scientists, and complemented with survey studies. Thus, this research may constitute merely a starting point for further explorations, including elaboration of good practices with respect to usage of social media by scientists.

ObjectiveAuthorship and number of publications are important criteria used for making decisions about promotions and research funding awards. Given the increase in the number of author positions over the last few decades, this study sought to determine if there had been a shift in the distribution of authorship among those publishing in high-impact academic medical journals over the last 12 years.DesignThis study analysed the distribution of authorship across 312 222 original articles published in 134 medium-impact to high-impact academic medical journals between 1 January 2008 and 31 December 2019. Additionally, this study compared the trends in author distributions across nine medical specialties and a collection of cross-specialty high-impact journal articles.Primary outcome measuresThe distribution of authorship was assessed using the Gini coefficient (GC), a widely used measure of economic inequality.ResultsThe overall GC for all articles sampled across the 12-year study period was 0.49, and the GCs for the first and last authorship positions were 0.30 and 0.44, respectively. Since 2008, there was a significant positive correlation between year and GC for the overall authorship position (r=0.99, p<0.001) the first author position (r=0.75, p=0.007) and the last author position (r=0.85, p<0.001) indicating increasingly uneven distribution in authorship over time. The cross-specialty high-impact journals exhibited the greatest rate of increase in GC over the study period for the first and last author position of any specialty analysed.ConclusionOverall, these data suggest a growing inequality in authorship across authors publishing in high-impact academic medical journals, especially among the highest impact journals. These findings may have implications for processes such as promotions and allocation of research funding that use authorship metrics as key criteria for making decisions.

BACKGROUND: The qualitative and quantitative scientific output of Brazilian dermatologists in journals of high impact factor is little known. OBJECTIVE: To describe the scientific output of dermatologists from Brazilian institutions in journals of high impact factor. METHODS: The five journals with the highest impact factor in dermatology were analyzed. All articles produced from Brazilian institutions between 1986 and 2010 were compiled and the following aspects were analyzed: position of Brazilian researchers in the list of authors, selected theme, experimental design, studied disease, area of interest and year of publication. RESULTS: Seventy-four articles written with the participation of Brazilian dermatologists have been identified. Upon grouping the articles in five-year periods, an important increase was observed in the Brazilian production from the year 2006 onwards. The dermatologists were placed as second authors in the majority of cases (53.66%). According to the selected theme to be studied, the majority of the articles had a laboratory focus (45.95%). The majority of the articles reported cross-sectional studies or non-controlled clinical trials (both at 17.57%), and pemphigus foliaceus was the most studied disease (29.73%). CONCLUSION: The increase in the number of publications by Brazilian dermatologists over the last years is encouraging, but it is still small in comparison to the total number of articles published in these five periodicals.
