    [Chocolate consumption and Hungarian Nobel laureates].

      INTRODUCTION: Certain dietary items contain significant amounts of flavonoids which was shown to improve cognitive function. An earlier investigation demonstrated a strong linear correlation between chocolate consumption and the number of Nobel laureates in a given country. However, Hungary and the Hungarian Nobel laureates were not included in this analysis.AIM: In this publication, we aim to complement these data by analyzing data available for Hungary.
    METHOD: The number of Nobel laureates per country and the international data on chocolate consumption were based on the previously published results. The amount of chocolate consumption in Hungary was based on data from the Hungarian Central Statistical Office. GDP per capita and Research and Development Expenditure data for the investigated countries were derived from the World Bank.
    RESULTS: There are 11 Nobel laureates from Hungary. Based on this, Hungary ranks the 9th amongst the 24 studied countries. However, it only ranks the 19th when it comes to chocolate consumption. Correlations were found between the number of Nobel laureates and GDP per capita (r = 0.734; p = 0.001) as well as Research and Development Expenditure (r = 0.532; p = 0.01) amongst the studied countries.
    CONCLUSION: The achievements of Hungarian scholars do not support the earlier notion that there is a link between the number of Nobel laureates (cognitive function) and the chocolate consumption in a given country. Their biographies highlight the importance and more possibilities of research funding in wealthier countries. Orv Hetil. 2019; 160(1): 26-29.

    Diabetic Foot Disease Research in Gulf Cooperation Council Countries: A bibliometric analysis.
    Ibrahim S Al-Busaidi, Nadia N Abdulhadi, Kirsten J Coppell.
      Objectives: Countries in the Gulf Cooperation Council (GCC) have some of the highest prevalence rates of diabetes mellitus (DM) in the world; however, DM-related research activity in this region is limited. This study aimed to examine trends in published diabetic foot disease (DFD) research undertaken in GCC countries.Methods: This bibliometric study was conducted in December 2016. Standardised criteria were used to search the MEDLINE® database (National Library of Medicine, Bethesda, Maryland, USA) for DFD-related publications authored by GCC researchers between January 1990 and December 2015. Various details such as the type of publication, journal impact factor and number of article citations were analysed.
    Results: A total of 96 research articles were identified. The number of publications per year significantly increased from nil prior to 1991 to 15 in 2015 (P <0.01). Basic/clinical research articles accounted for 96.9% of publications, with three randomised controlled trials and no systematic reviews/meta-analyses. When adjusted for population size, Kuwait had the highest number of published papers per year, followed by Bahrain and Qatar. The number of authors per publication significantly increased during the study period (P = 0.02). However, 16 articles (16.7%) had no citations. The median journal impact factor was 0.15 ± 1.19 (range: 0-6.04).
    Conclusion: The number of publications authored by GCC researchers has risen in recent years. Increasing research funding and promoting collaboration between local and international researchers and institutes are recommended to bolster research regarding DFD prevention and management in GCC countries.

    Topics and methods in economics, finance, and business journals: A content analysis enquiry.
    Jorge Camargo, Maximiliano González, Alexander Guzmán, Enrique Ter Horst, María-Andrea Trujillo.
      This study analyzes the abstracts and titles of 33,454 business finance, economics, management, and business articles published in ISI (frequently cited) journals during 2013-14. The sample represents 46.4 percent of all papers published in ISI journals in those years, and 52.7 percent of the articles published in the selected categories. The journals were ranked in four Q categories according to their impact factors. The analysis revealed that some topics persisted in all Q groups, but others gained frequency by Q, which suggests that Q1 journals (those with higher impact factors) create trends that are followed by other publications. All Q groups have a methodological approach that is predominantly empirical rather than theoretical. In addition, while the business and management categories privileged case studies, economics studies emphasized panel data analyses. Finally, our study confirms the relevance of the English language in academia.

    Scientific collaboration of Cuban researchers working in Europe: understanding relations between origin and destination countries.
    Miriam Palacios-Callender, Stephen A Roberts.
      The global network of scientific collaboration created by researchers opens new opportunities for developing countries to engage in the process of knowledge creation historically lead by institutions in the developed world. The results discussed here explore how Cubans working in European science and technology might contribute to extending the scientific collaboration of the country through their ties with Cuban institutions mainly in the academic sector. A bibliometric method was used to explore the pattern of collaboration of Cuban researchers in Europe using the institutional affiliation of authors and collaborators. The records of scientific publications of the defined sample were obtained from Scopus database for the period between 1995 and 2014. The network of collaboration was generated using the affiliations of Cuban authors in Europe and co-authors with worldwide affiliations shown in the records of publications of each Cuban researcher of the study. The analysis of aggregate values of the output of Cuban researchers in Europe (1995-2014) reveals that their collaboration with Cuba correlates moderately with their performance in Europe. However, when taking into account their time publishing in Europe, the collaboration with Cuba decreases the longer they remain away from home. The network of collaborating Cuban researchers in Europe comprises 991 different affiliations from 58 countries: 698 from Europe, 118 from North America, 96 from Latin America and 79 from the rest of the world. K-core analysis of centrality shows two Cuban universities sharing the central position with another 24 institutions worldwide of which 18 belong to higher education.

    Intradepartment scientific collaboration in Journal of Research in Medical Sciences: A co-authorship study.
    Ehsan Geraei, Elaheh Mazaheri, Maryam Karimi.
      Background: This study aimed to use social network analysis (SNA) indicators and clique analysis to investigate collaboration between different departments and research centers in Journal of Research in Medical Sciences (JRMS) in 2012-2016.Materials and Methods: The study was a scientometric study using micro- and macro-indicators of SNA to investigate the performance of departments and research centers in JRMS. The population consisted of 1073 articles published in JRMS in 2012-2016. Ravar Matrix, UCINET, and VOSviewer software were used for data analysis.
    Results: According to the productivity and triple centrality indicators, "Department of Epidemiology and Biostatistics," "Department of Pathology," and Department of "Internal Medicine" allocated the first three ranks. Analyzing the cliques of co-authorship network for departments and research centers showed that this network consists of 19 cliques with at least 7 members in each clique. Furthermore, only 30 nodes (8.90% of all nodes in the network) had the presence in minimum clique size of at least 7.
    Conclusion: Given the importance and position of scientific collaboration in medical research and its effect on other performance indicators such as efficiency, effectiveness, and number of citations, it is necessary for policy-makers to propose new strategies for improving scientific collaboration.

    [The publication performance of German academic vascular surgery-journals, focal topics and impact factors].
    F Haffke, E S Debus, R T Grundmann.
      AIM: The aim of the present study was to describe the publication performance of the academic surgical management teams in Germany based on the preferred journals, their impact factors (IF) and the focal topics.METHODS: The publications of the vascular surgical management teams, consisting of chief and senior physicians, of 37 German university hospitals were analyzed. Reference date for all considerations (staffing and publications) was 1 July 2017. The publication period covered the last 10 years. The literature search was based on an evaluation of the PubMed database.
    RESULTS: A total of 1047 publications published in 197 journals were recorded. Among them were 3 German language journals with 136 (13.0%) publications but only 3.3% of all cumulative IFs. In 126 journals (64.0%) only one article was published and in 30 (15.2%) two articles. The three PubMed listed journals in which German university vascular surgeons published most frequently were the J Vasc Surg with 126 publications, Eur J Vasc Endovasc Surg with 94 and J Endovasc Ther with 88 publications. Of all 1047 publications 46.5% were published in an IF range under 2 and a total of 907/1047 publications (86.6%) in an IF range under 4. In 8.6% of the journals 44.1% of the IFs were generated. In terms of publication topics, thoracic and abdominal aorta were at the top of the list, accounting for almost half of all publications with 501 publications and with 52% of all 1252.08 accumulated IFs.
    CONCLUSION: A total of 78.6% of the publications in the 17 journals, in which more than 10 publications were made, came from independent institutions, 19.3% from the sections. None of the 91 publications in journals with an IF > 4 came from a subordinate organizational structure, indicating a gap between independent departments, sections and subordinate structures. The number of publications was based on the achievable IF of the individual topic and thus its attractiveness. Peripheral arterial disease was underrepresented in the publication topics in relation to the number of patients, with a share of 8.5.
